     The Mortgage Loans will be sold to the Depositor by IndyMac, Inc.
('IndyMac').
 
     An election will be made to treat the Trust Fund as a 'real estate mortgage
investment conduit' (a 'REMIC') for federal income tax purposes. As described
more fully herein and in the Prospectus, the Certificates, other than the Class
A-R Certificates, will be designated as the 'regular interests' in the REMIC.
The Class A-R Certificates will constitute the beneficial ownership of the
'residual interests' in the REMIC. Prospective investors are cautioned that a
Class A-R Certificateholder's REMIC taxable income and the tax liability thereon
will exceed cash distributions in certain periods, in which event such holder
must have sufficient alternative sources of funds to pay such tax liability. See
'Certain Federal Income Tax Consequences' herein and 'Federal Income Tax
Consequences' in the Prospectus.
 
     The Class A-R Certificates will be subject to certain transfer
restrictions. See 'Description of the Certificates -- Restrictions on Transfer
of the Class A-R Certificates' herein.
 
     THE YIELD TO INVESTORS ON EACH CLASS OF OFFERED CERTIFICATES WILL BE
SENSITIVE IN VARYING DEGREES TO, AMONG OTHER THINGS, THE RATE AND TIMING OF
PRINCIPAL PAYMENTS (INCLUDING PREPAYMENTS) OF THE MORTGAGE LOANS IN THE RELATED
LOAN GROUP, WITH RESPECT TO THE SENIOR CERTIFICATES, AND ALL OF THE MORTGAGE
LOANS, WITH RESPECT TO THE SUBORDINATED CERTIFICATES. THE YIELD TO MATURITY OF A
CLASS OF OFFERED CERTIFICATES PURCHASED AT A DISCOUNT OR PREMIUM WILL BE MORE
SENSITIVE TO THE RATE AND TIMING OF PAYMENTS THEREON. HOLDERS OF THE OFFERED
CERTIFICATES SHOULD CONSIDER, IN THE CASE OF ANY SUCH CERTIFICATES PURCHASED AT
A DISCOUNT, AND PARTICULARLY THE CLASS PO CERTIFICATES, THE RISK THAT A SLOWER
THAN ANTICIPATED RATE OF PRINCIPAL PAYMENTS ON THE MORTGAGE LOANS IN THE RELATED
LOAN GROUP, WITH RESPECT TO THE THE SENIOR CERTIFICATES, AND ALL OF THE MORTGAGE
LOANS, WITH RESPECT TO THE SUBORDINATED CERTIFICATES, COULD RESULT IN AN ACTUAL
YIELD THAT IS LOWER THAN THE ANTICIPATED YIELD AND, IN THE CASE OF ANY OFFERED
CERTIFICATES PURCHASED AT A PREMIUM, AND PARTICULARLY THE NOTIONAL AMOUNT
CERTIFICATES, THE RISK THAT A FASTER THAN ANTICIPATED RATE OF PRINCIPAL PAYMENTS
ON THE MORTGAGE LOANS IN THE RELATED LOAN GROUP COULD RESULT IN AN ACTUAL YIELD
THAT IS LOWER THAN THE ANTICIPATED YIELD. HOLDERS OF THE NOTIONAL AMOUNT
CERTIFICATES SHOULD CAREFULLY CONSIDER THE RISK THAT A RAPID RATE OF PRINCIPAL
PAYMENTS ON THE MORTGAGE LOANS IN THE RELATED LOAN GROUP COULD RESULT IN THE
FAILURE OF SUCH HOLDERS TO RECOVER THEIR INITIAL INVESTMENTS. THE YIELD TO
INVESTORS IN THE INVERSE FLOATING RATE CERTIFICATES WILL BE ADVERSELY AFFECTED
BY A HIGH LEVEL OF LIBOR. THE YIELDS TO INVESTORS IN THE OFFERED CERTIFICATES,
AND PARTICULARLY THE CLASS B-1, CLASS B-2 AND CLASS B-3 CERTIFICATES, ALSO WILL
BE ADVERSELY AFFECTED BY NET INTEREST SHORTFALLS AND BY REALIZED LOSSES. NO
REPRESENTATION IS MADE AS TO THE ANTICIPATED RATE OF PREPAYMENTS ON THE MORTGAGE
LOANS, THE AMOUNT AND TIMING OF NET INTEREST SHORTFALLS OR REALIZED LOSSES, OR
THE RESULTING YIELD TO MATURITY OF ANY CLASS OF CERTIFICATES.
 
     Each Underwriter intends to make a secondary market in the Classes of
Underwritten Certificates being purchased by it, but no Underwriter has any
obligation to do so. There is currently no secondary market for the Offered
Certificates and there can be no assurance that such a market will develop or,
if it does develop, that it will continue or that it will provide
Certificateholders with a sufficient level of liquidity of investment.
 
     This Prospectus Supplement does not contain complete information about the
offering of the Offered Certificates. Additional information is contained in the
Prospectus of the Depositor dated June 25, 1998 (the 'Prospectus') and
purchasers are urged to read both this Prospectus Supplement and the Prospectus
in full. Sales of the Offered Certificates may not be consummated unless the
purchaser has received both this Prospectus Supplement and the Prospectus.
 
     UNTIL NINETY DAYS AFTER THE DATE OF THIS PROSPECTUS SUPPLEMENT, ALL DEALERS
EFFECTING TRANSACTIONS IN THE OFFERED CERTIFICATES, WHETHER OR NOT PARTICIPATING
IN THIS DISTRIBUTION, MAY BE REQUIRED TO DELIVER A PROSPECTUS SUPPLEMENT AND THE
PROSPECTUS. THIS IS IN ADDITION TO THE OBLIGATION OF DEALERS TO DELIVER A
PROSPECTUS SUPPLEMENT AND THE PROSPECTUS WHEN ACTING AS UNDERWRITERS AND WITH
RESPECT TO THEIR UNSOLD ALLOTMENTS OR SUBSCRIPTIONS.

                                      LIBOR will be determined as described herein under 'Description of the
                                      Certificates -- Determination of LIBOR.'
Distributions of Principal..........  On each Distribution Date, to the extent funds are available therefor,
                                      principal distributions in reduction of the Class Certificate Balance of
                                      each Class of Certificates (other than the Notional Amount Certificates)
                                      will be made in the order and subject to the priorities set forth herein
                                      under 'Description of the Certificates -- Principal' in an aggregate amount
                                      equal to such Class' allocable portion of the Senior Principal Distribution
                                      Amount, the Class PO Principal Distribution Amount or the Subordinated
                                      Principal Distribution Amount, as applicable. The Notional Amount
                                      Certificates do not have principal balances and are not entitled to any
                                      distributions in respect of principal. See 'Description of the
                                      Certificates -- Principal' herein.
Credit Enhancement -- General.......  Credit enhancement for the Senior Certificates will be provided by the
                                      Subordinated Certificates. Credit enhancement for each Class of
                                      Subordinated Certificates (other than the Class B-6 Certificates) will be
                                      provided by the Class or Classes of Subordinated Certificates with higher
                                      numerical Class designations, as described below. The aggregate of the
                                      initial Class Certificate Balances of the Class B-4, Class B-5 and Class
                                      B-6 Certificates, which are the only Certificates supporting the Class B-3
                                      Certificates, is expected to be approximately $10,629,241.
Subordination.......................  The rights of holders of the Subordinated Certificates to receive
                                      distributions with respect to the Mortgage Loans in the Trust Fund will be
                                      subordinated to such rights of the holders of the Senior Certificates, and
                                      the rights of the holders of each Class of Subordinated Certificates (other
                                      than the Class B-1 Certificates) to receive distributions will be further
                                      subordinated to such rights of the holders of the Class or Classes of
                                      Subordinated Certificates with lower numerical Class designations, in each
                                      case only to the extent described herein.
                                      The subordination of the Subordinated Certificates to the Senior
                                      Certificates and the further subordination within the Subordinated
                                      Certificates are each intended to increase the likelihood of timely receipt

                                      by the holders of Certificates with higher relative payment priority of the
                                      maximum amount to which they are entitled on any Distribution Date and to
                                      provide such holders protection against losses resulting from defaults on
                                      Mortgage Loans to the extent described herein. The Subordinated
                                      Certificates also provide protection to a lesser extent against Special
                                      Hazard Losses, Bankruptcy Losses and Fraud Losses. However, in certain
                                      circumstances, the amount of available subordination (including the limited
                                      subordination provided for certain types of losses) may be exhausted and
                                      shortfalls in distributions on the Certificates could result. Holders of
                                      Senior Certificates in a Senior Certificate Group will bear their
                                      proportionate share of any losses realized on the Mortgage Loans of the
                                      related Loan Group in excess of the available subordination amount. Because
                                      the Subordinated Certificates provide credit enhancement for all of the
                                      Senior Certificate Groups, it is possible that one or more of the Senior
                                      Certificate Groups could use a disproportionate amount of the credit
                                      enhancement provided by the Subordinated Certificates. See 'Description of
                                      the Certificates -- Priority of Distributions Among Certificates,'
                                      ' -- Allocation of Losses' and 'Credit Enhancement -- Subordination of
                                      Certain Classes' herein.
Advances............................  The Master Servicer is obligated to make cash advances ('Advances') with
                                      respect to delinquent payments of principal and interest on any Mortgage
                                      Loan to the extent described herein. The Trustee will be obligated to make
                                      any such Advance if the Master Servicer fails in its obligation to do so,
                                      to the extent provided in the Agreement. See 'Servicing of Mortgage
                                      Loans -- Advances' herein.
Prepayment Considerations and Risks;
  Reinvestment Risk.................  The rate of principal payments on the Offered Certificates, the aggregate
                                      amount of distributions on the Offered Certificates and the yield to
                                      maturity of the Offered Certificates will be related to the rate and timing
                                      of payments of principal on the Mortgage Loans in the related Loan Group,
                                      with respect to the Senior Certificates, and all of the Mortgage Loans,
                                      with respect to the Subordinated Certificates.
                                      Since the rate of payment of principal on the Mortgage Loans will depend on
                                      future events and a variety of other factors, no assurance can be given as
                                      to such rate or the rate of principal prepayments. The extent to which the
                                      yield to maturity of a Class of Offered Certificates may vary from the
                                      anticipated yield may depend upon the degree to which it is purchased at a
                                      discount or premium, and the degree to which the timing of payments thereon
                                      is sensitive to prepayments, liquidations and purchases of the Mortgage
                                      Loans in the related Loan Group, with respect to the Senior Certificates,
                                      and all of the Mortgage Loans, with respect to the Subordinated
                                      Certificates. Further, an investor should consider the risk that, in the
                                      case of the Class PO Certificates and any other Offered Certificates
                                      purchased at a discount, a slower than anticipated rate of principal
                                      payments (including prepayments) on such Mortgage Loans could result in an
                                      actual yield to such investor that is lower than the anticipated yield and,
                                      in the case of the Notional Amount Certificates and any other Offered
                                      Certificates purchased at a premium, a faster than anticipated rate of
                                      principal payments on such Mortgage Loans could result in an actual yield
                                      to such investor that is lower than the anticipated yield. Investors in the
                                      Notional Amount Certificates should carefully consider the risk that a
                                      rapid rate of principal payments on the Mortgage

                                      Loans in the related Loan Group could result in the failure of such
                                      investors to recover their initial investments.
                                      Because the Mortgage Loans may be prepaid at any time, it is not possible
                                      to predict the rate at which distributions of principal of the Offered
                                      Certificates will be received. Since prevailing interest rates are subject
                                      to fluctuation, there can be no assurance that investors in the Offered
                                      Certificates will be able to reinvest the distributions thereon at yields
                                      equaling or exceeding the yields on such Offered Certificates. It is
                                      possible that yields on any such reinvestments will be lower, and may be
                                      significantly lower, than the yields on the Offered Certificates. The yield
                                      to investors in the Inverse Floating Rate Certificates will be adversely
                                      affected by a high level of LIBOR. See 'Yield, Prepayment and Maturity
                                      Considerations' herein.
Optional Termination................  On any Distribution Date on which the Pool Principal Balance is less than
                                      10% of the Cut-off Date Pool Principal Balance, the Master Servicer will
                                      have the option to purchase, in whole, the Mortgage Loans and the REO
                                      Property, if any, remaining in the Trust Fund. See 'Description of the
                                      Certificates -- Optional Termination' herein.
Federal Income Tax Considerations...  An election will be made to treat the Trust Fund as a 'real estate mortgage
                                      investment conduit' (a 'REMIC') for federal tax purposes . The Regular
                                      Certificates will constitute 'regular interests' in the REMIC. The Class
                                      A-R Certificates will represent the sole class of 'residual interest' in
                                      the REMIC.
                                      The Principal Only Certificates and the Notional Amount Certificates will,
                                      and depending on their respective issue prices certain other Classes of
                                      Offered Certificates may, be issued with original issue discount ('OID')
                                      for federal income tax purposes. See 'Certain Federal Income Tax
                                      Consequences' herein and 'Federal Income Tax Consequences' in the
                                      Prospectus.
                                      The holders of the Class A-R Certificates will be subject to special
                                      federal income tax rules that may significantly reduce the after-tax yield
                                      of such Certificates. Further, significant restrictions apply to the
                                      transfer of the Class A-R Certificates. See 'Description of the
                                      Certificates -- Restrictions on Transfer of the Class A-R Certificates'
                                      herein.
ERISA Considerations................  The acquisition of an Offered Certificate by a pension or other employee
                                      benefit plan (a 'Plan') subject to the Employee Retirement Income Security
                                      Act of 1974, as amended ('ERISA'), could, in some instances, result in a
                                      prohibited transaction or other violation of the fiduciary responsibility
                                      provisions of ERISA and Section 4975 of the Internal Revenue Code of 1986,
                                      as amended (the 'Code').
                                      Subject to the considerations and conditions described under 'ERISA
                                      Considerations' herein, it is expected that the Class A Certificates (other
                                      than the Class A-R Certificates) may be purchased by a Plan.
                                      Any Plan fiduciary considering whether to purchase any Offered Certificates
                                      on behalf of a Plan should consult with its counsel regarding the
                                      applicability of the provisions of ERISA and the Code. See 'ERISA
                                      Considerations' herein.
Legal Investment....................  The Senior Certificates and the Class B-1 Certificates will constitute

                                      investments for certain entities to the extent provided for in SMMEA.
                                      It is anticipated that the Class B-2 and Class B-3 Certificates will not be
                                      rated in one of the two highest rating categories by a nationally
                                      recognized statistical rating organization and, therefore, will not

                                      or state regulatory authorities should consult with their counsel or the
                                      applicable authorities to determine whether an investment in the Offered
                                      Certificates complies with applicable guidelines, policy statements or
                                      restrictions. See 'Legal Investment' in the Prospectus.
Ratings.............................  It is a condition of the issuance of the Senior Certificates that they be
                                      rated AAA by Duff & Phelps Credit Rating Company ('DCR') and that the
                                      Senior Certificates, other than the Class PO-1, Class PO-2, Class PO-3,
                                      Class X-1, Class X-2 and Class X-3 Certificates, be rated AAA by Standard &
                                      Poor's, a division of The McGraw-Hill Companies, Inc. ('S&P' and, together
                                      with DCR, the 'Rating Agencies'). It is a condition to the issuance of the
                                      Class PO-1, Class PO-2, Class PO-3, Class X-1, Class X-2 and Class X-3
                                      Certificates that they be rated AAAr by S&P. It is a condition to the
                                      issuance of the Class B-1, Class B-2 and Class B-3 Certificates that they
                                      be rated at least AA, A and BBB, respectively, by DCR. The ratings of the
                                      Offered Certificates of any Class should be evaluated independently from
                                      similar ratings on other types of securities. A rating is not a
                                      recommendation to buy, sell or hold securities and may be subject to
                                      revision or withdrawal at any time by the Rating Agencies.
                                      The Depositor has not requested a rating of the Offered Certificates by any
                                      rating agency other than the Rating Agencies; there can be no assurance,
                                      however, as to whether any other rating agency will rate the Offered
                                      Certificates or, if it does, what rating would be assigned by such other
                                      rating agency. The rating assigned by such other rating agency to the
                                      Offered Certificates could be lower than the respective ratings assigned by
                                      the Rating Agencies. See 'Ratings' herein.

                               THE MORTGAGE POOL
 
GENERAL
 
     The Depositor will purchase the Mortgage Loans from IndyMac, Inc.
('IndyMac') pursuant to the Pooling and Servicing Agreement dated as of the
Cut-off Date among IndyMac, as Seller and Master Servicer, the Depositor and the
Trustee (the 'Agreement') and will cause the Mortgage Loans to be assigned to
the Trustee for the benefit of holders of the Certificates (the
'Certificateholders').
 
     Under the Agreement, the Seller will make certain representations,
warranties and covenants to the Depositor relating to, among other things, the
due execution and enforceability of the Agreement and certain characteristics of
the Mortgage Loans and, subject to the limitations described below under
' -- Assignment of Mortgage Loans,' will be obligated to repurchase or
substitute a similar mortgage loan for any Mortgage Loan as to which there
exists deficient documentation or as to which there has been an uncured breach
of any representation or warranty relating to the characteristics of the
Mortgage Loans that materially and adversely affects the interests of the
Certificateholders in such Mortgage Loan. The Seller will represent and warrant
to the Depositor in the Agreement that the Mortgage Loans were selected from
among the outstanding one- to four-family mortgage loans in the Seller's
portfolio as to which the representations and warranties set forth in the
Agreement can be made and that such selection was not made in a manner intended
to adversely affect the interests of the Certificateholders. See 'Loan
Program -- Representations by Sellers; Repurchases' in the Prospectus. Under the
Agreement, the Depositor will assign all its right, title and interest in and to
such representations, warranties and covenants (including the Seller's
repurchase obligation) to the Trustee for the benefit of the Certificateholders.
The Depositor will make no representations or warranties with respect to the
Mortgage Loans and will have no obligation to repurchase or substitute Mortgage
Loans with deficient documentation or which are otherwise defective. IndyMac is
selling the Mortgage Loans without recourse and will have no obligation with
respect to the Certificates in its capacity as Seller other than the repurchase
or substitution obligations described above. The obligations of IndyMac, as
Master Servicer, with respect to the Certificates are limited to the Master
Servicer's contractual servicing obligations under the Agreement.
 
     Certain information with respect to the Mortgage Loans to be included in
the Mortgage Pool is set forth below. Prior to the Closing Date, Mortgage Loans
may be removed from the Mortgage Pool and other Mortgage Loans may be
substituted therefor. The Depositor believes that the information set forth
herein with respect to the Mortgage Pool as presently constituted is
representative of the characteristics of the Mortgage Pool as it will be
constituted at the Closing Date, although certain characteristics of the
Mortgage Loans in the Mortgage Pool may vary. Unless otherwise indicated,
information presented below expressed as a percentage (other than rates of
interest) are approximate percentages based on the Stated Principal Balances of
the Mortgage Loans as of the Cut-off Date.
 
     As of the Cut-off Date, the aggregate of the Stated Principal Balances of
the Mortgage Loans is expected to be approximately $850,277,664 (the 'Cut-off
Date Pool Principal Balance'). The Mortgage Loans provide for the amortization
of the amount financed over a series of substantially equal monthly payments.
All of the Mortgage Loans provide for payments due on the first day of each
month (the 'Due Date'). The Mortgage Loans to be included in the Mortgage Pool
were acquired by the Seller in the normal course of its business and
substantially in accordance with the underwriting criteria specified herein. At
origination, substantially all of the Mortgage Loans had stated terms to
maturity of 30 years. Scheduled monthly payments made by the Mortgagors on the
Mortgage Loans ('Scheduled Payments') 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. Mortgagors may prepay
their Mortgage Loans at any time without penalty.
 
     Each Mortgage Loan in Loan Group 1 was originated on or after December 1,
1996, each Mortgage Loan in Loan Group 2 was originated on or after July 1,
1994, and each Mortgage Loan in Loan Group 3 was originated on or after May 1,
1995.
 
     The latest stated maturity date of any Mortgage Loan in Loan Group 1 is
August 1, 2028, and the earliest stated maturity date of any Mortgage Loan in
Loan Group 1 is May 1, 2018. The latest stated maturity date of any Mortgage
Loan in Loan Group 2 is August 1, 2028, and the earliest stated maturity date of
any Mortgage Loan in Loan Group 2 is April 1, 2018. The latest stated maturity
date of any Mortgage Loan in Loan Group 3 is August 1, 2028, and the earliest
stated maturity date of any Mortgage Loan in Loan Group 3 is November 1, 2026.

     As of the Cut-off Date, no Mortgage Loan will be delinquent more than 30
days.
 
     No Mortgage Loan is subject to a buydown agreement. No Mortgage Loan
provides for deferred interest or negative amortization.
 
     Except for 46 Mortgage Loans representing approximately 0.870% of the
Cut-off Date Pool Principal Balance, each of the Mortgage Loans had a
Loan-to-Value Ratio at origination of 95% or less. Except for 320 Mortgage
Loans, representing approximately 5.727% of the Cut-off Date Pool Principal
Balance, each of the Mortgage Loans with a Loan-to-Value Ratio at origination of
greater than 80% will be covered by a primary mortgage guaranty insurance policy
issued by a mortgage insurance company acceptable to the Federal National
Mortgage Association ('FNMA'), the Federal Home Loan Mortgage Corporation
('FHLMC') or any nationally recognized statistical rating organization, which
policy provides coverage of a portion of the original principal balance of the
related Mortgage Loan equal to the product of the original principal balance
thereof and a fraction, the numerator of which is the excess of the original
principal balance of the related Mortgage Loan over 75% of the lesser of the
appraised value and selling price of the related Mortgaged Property and the
denominator of which is the original principal balance of the related Mortgage
Loan, plus accrued interest thereon and related foreclosure expenses. No such
primary mortgage guaranty insurance policy will be required with respect to any
such Mortgage Loan after the date on which the related Loan-to-Value Ratio is
80% or less or, based on a new appraisal, the principal balance of such Mortgage
Loan represents 80% or less of the new appraised value. See ' -- Underwriting
Standards' herein.
 
     The 'Loan-to-Value Ratio' of a Mortgage Loan at any given time is a
fraction, expressed as a percentage, the numerator of which is the principal
balance of the related Mortgage Loan at the date of determination and the
denominator of which is (a) in the case of a purchase, the lesser of the selling
price of the Mortgaged Property and its appraised value determined in an
appraisal obtained by the originator at origination of such Mortgage Loan, or
(b) in the case of a refinance, the appraised value of the Mortgaged Property at
the time of such refinance. No assurance can be given that the value of any
Mortgaged Property has remained or will remain at the level that existed on the
appraisal or sales date. If residential real estate values generally or in a
particular geographic area decline, the Loan-to-Value Ratios might not be a
reliable indicator of the rates of delinquencies, foreclosures and losses that
could occur with respect to such Mortgage Loans.
 
     The following information sets forth in tabular format certain information,
as of the Cut-off Date, as to the Mortgage Loans in each Loan Group. Other than
with respect to rates of interest, percentages (approximate) are stated by
Stated Principal Balance of the Mortgage Loans in the related Loan Group as of
the Cut-off Date and have been rounded in order to total 100%.

ASSIGNMENT OF THE MORTGAGE LOANS
 
     Pursuant to the Agreement, the Depositor on the Closing Date will sell,
transfer, assign, set over and otherwise convey without recourse to the Trustee
in trust for the benefit of the Certificateholders all right, title and interest
of the Depositor in and to each Mortgage Loan and all right, title and interest
in and to all other assets included in the Trust Fund, including all principal
and interest received on or with respect to the Mortgage Loans, exclusive of
principal and interest due on or prior to the Cut-off Date.
 
     In connection with such transfer and assignment, the Depositor will deliver
or cause to be delivered to the Trustee, or a custodian for the Trustee, among
other things, the original promissory note (the 'Mortgage Note') (and any
modification or amendment thereto) endorsed in blank without recourse, except
that the Depositor may deliver or cause to be delivered a lost note affidavit in
lieu of any original Mortgage Note that has been lost, the original instrument
creating a first lien on the related Mortgaged Property (the 'Mortgage') with
evidence of recording indicated thereon, an assignment in recordable form of the
Mortgage, the title policy with respect to the related Mortgaged Property and,
if applicable, all recorded intervening assignments of the Mortgage and any
riders or modifications to such Mortgage Note and Mortgage (except for any such
document not returned from the public recording office, which will be delivered
to the Trustee as soon as the same is available to the Depositor) (collectively,
the 'Mortgage File'). Assignments of the Mortgage Loans to the Trustee (or its
nominee) will be recorded in the appropriate public office for real property
records, except in states such as California where, in the opinion of counsel,
such recording is not required to protect the Trustee's interest in the Mortgage
Loan against the claim of any subsequent transferee or any successor to or
creditor of the Depositor or the Seller.
 
     The Trustee will review each Mortgage File within 90 days of the Closing
Date (or promptly after the Trustee's receipt of any document permitted to be
delivered after the Closing Date) and if any document in a Mortgage File is
found to be missing or defective in a material respect and the Seller does not
cure such defect within 90 days of notice thereof from the Trustee (or within
such longer period not to exceed 720 days after the Closing Date as provided in
the Agreement in the case of missing documents not returned from the public
recording office), the Seller will be obligated to repurchase the related
Mortgage Loan from the Trust Fund. Rather than repurchase the Mortgage Loan as
provided above, the Seller may remove such Mortgage Loan (a 'Deleted Mortgage
Loan') from the Trust Fund and substitute in its place another mortgage loan (a
'Replacement Mortgage Loan'); however, such substitution is permitted only
within two years of the Closing Date and may not be made unless an opinion of
counsel is provided to the effect that such substitution will not disqualify the
REMIC or result in a prohibited transaction tax under the Code. Any Replacement
Mortgage Loan generally will, on the date of substitution, among other
characteristics set forth in the Agreement, (i) have a principal balance, after
deduction of all Scheduled Payments due in the month of substitution, not in
excess of, and not more than 10% less than, the Stated Principal Balance of the
Deleted Mortgage Loan (the amount of any shortfall to be deposited by the Seller
and held for distribution to the Certificateholders on the related Distribution
Date (a 'Substitution Adjustment Amount')), (ii) have a Mortgage Rate not lower
than, and not more than 1% per annum higher than, that of the Deleted Mortgage
Loan, (iii) have a Loan-to-Value Ratio not higher than that of the Deleted
Mortgage Loan, (iv) have a remaining term to maturity not greater than (and not
more than one year less than) that of the Deleted Mortgage Loan, and (v) comply
with all of the representations and warranties set forth in the Agreement as of
the date of substitution. This cure, repurchase or substitution obligation
constitutes the sole remedy available to Certificateholders or the Trustee for
omission of, or a material defect in, a Mortgage Loan document.
 
UNDERWRITING STANDARDS
 
     IndyMac operates a conduit program established in April 1993 to purchase
'conventional non-conforming mortgage loans' (i.e., loans which are not insured
by the FHA or partially guaranteed by the VA or which do not qualify for sale to
FNMA or FHLMC) secured by first liens on one- to four- family residential
properties. Non-conforming loans purchased by IndyMac pursuant to its
underwriting programs typically differ from those purchased pursuant to the
guidelines established by FNMA, FHLMC and the Government National Mortgage
Association ('GNMA') primarily with respect to loan-to-value ratios, borrower
income, required documentation, interest rates, borrower occupancy of the
mortgaged property and/or property types. To the extent that these programs
reflect underwriting standards different from those of FNMA, FHLMC and GNMA, the
performance of loans made thereunder may reflect higher delinquency rates and/or
credit losses.
 
                                      S-19
 

<PAGE>
<PAGE>

     IndyMac purchases mortgage loans from banks, savings and loan associations,
mortgage bankers (which may or may not be affiliated with IndyMac) and other
mortgage loan originators (each, a 'Seller/Servicer'). Each Seller/Servicer must
be an approved HUD mortgagee in good standing or a seller/servicer in good
standing and approved by either FNMA or FHLMC. IndyMac approves individual
institutions as eligible Seller/Servicers after an evaluation of certain
criteria, including the Seller/Servicer's mortgage origination and servicing
experience and financial stability.
 
     IndyMac currently operates three mortgage loan purchase programs as part of
its conduit operations:
 
          1. Prior Approval Program. Under this program, IndyMac performs a full
     credit review and analysis of each mortgage loan to be purchased to ensure
     compliance with its underwriting guidelines. Only after IndyMac issues an
     approval notice to a Seller/Servicer is a mortgage loan eligible for
     purchase pursuant to this program.
 
          2. Standard Delivery Program. Under this program, IndyMac does not
     perform a full underwriting review prior to purchase of a mortgage loan,
     but instead relies on the credit review and analysis performed by a
     mortgage pool insurer previously selected by IndyMac and its own
     post-purchase quality review. Only mortgage loans with mortgage pool
     insurance commitments are eligible for purchase pursuant to this program.
 
          3. Preferred Delegated Underwriting Program. Under this program,
     Seller/Servicers which meet certain eligibility requirements (each, a 'PDU
     Seller/Servicer') are allowed to underwrite mortgage loans for purchase
     without the need for either prior pool insurance approval or prior IndyMac
     approval. The eligibility requirements for participation in the Preferred
     Delegated Underwriting Program vary based on the net worth of the
     Seller/Servicer with more stringent requirements imposed on
     Seller/Servicers with lower net worth. Under the Preferred Delegated
     Underwriting Program, each PDU Seller/Servicer is required to underwrite
     mortgage loans in compliance with IndyMac's underwriting guidelines, as the
     same may have been modified pursuant to commitments negotiated with such
     PDU Seller/Servicer. A greater percentage of mortgage loans purchased
     pursuant to this program are selected for post-purchase quality control
     review than for the other two programs. Notwithstanding the
     Seller/Servicer's status as a PDU Seller/Servicer, certain types of
     mortgage loans are required to receive an approval notice prior to
     purchase. The majority of mortgage loans currently being purchased by
     IndyMac are originated under the Preferred Delegated Underwriting Program.
 
     All mortgage loans purchased by IndyMac must meet credit, appraisal and
underwriting standards acceptable to IndyMac. Such underwriting standards,
including negotiated modifications thereto (the 'Underwriting Standards'), are
applied to evaluate the prospective borrower's credit standing and repayment
ability and the value and adequacy of the mortgaged property as collateral.
These standards are applied in accordance with applicable federal and state laws
and regulations. Exceptions to the Underwriting Standards are permitted where
compensating factors are present or in the context of negotiated bulk purchases.
In addition, the requirements of a mortgage pool insurer may differ from the
Underwriting Standards as a result of which mortgage loans certified by such
mortgage pool insurer may not comply with the Underwriting Standards.
 
     IndyMac's Underwriting Standards for purchase money or rate/term refinance
loans secured by primary residences generally allow Loan-to-Value Ratios at
origination of up to 95% for mortgage loans with original principal balances of
up to $400,000, up to 90% for mortgage loans with original principal balances of
up to $600,000, up to 85% for mortgage loans with original principal balances of
up to $750,000 and up to 80% for mortgage loans with original principal balances
of up to $1,500,000. IndyMac also acquires mortgage loans with principal
balances up to $3,000,000 ('super jumbos') if the loan is secured by the
borrower's primary residence. The Loan-to-Value Ratio for super jumbos generally
may not exceed 80%. For cash-out refinance loans, the maximum Loan-to-Value
Ratio generally is 80%, and the maximum 'cash out' amount permitted is based in
part on the Loan-to-Value Ratio of the related mortgage loan. IndyMac generally
does not purchase cash-out refinance mortgage loans with original principal
balances in excess of $3,000,000.
 
     IndyMac's Underwriting Standards for mortgage loans secured by investor
properties generally allow Loan-to-Value Ratios at origination of up to 90% for
mortgage loans with original principal balances up to $225,000. IndyMac's
Underwriting Standards permit mortgage loans secured by investor properties to
have higher original principal balances if they have lower Loan-to-Value Ratios
at origination.
 
     For each mortgage loan with a Loan-to-Value Ratio at origination exceeding
80%, IndyMac generally requires a primary mortgage guaranty insurance policy
insuring a portion of the balance of the mortgage loan equal to the product of
the original principal balance of such mortgage loan and a fraction, the
numerator of
 
                                      S-20
 

<PAGE>
<PAGE>

which is the excess of the original principal balance of such mortgage loan over
75% of the lesser of the appraised value and selling price of the related
mortgaged property and the denominator of which is the original principal
balance of the related mortgage loan plus accrued interest thereon and related
foreclosure expenses. No such primary mortgage guaranty insurance policy will be
required with respect to any such mortgage loan after the date on which the
related Loan-to-Value Ratio decreases to 80% or less or, based upon a new
appraisal, the principal balance of such mortgage loan represents 80% or less of
the new appraised value. All of the insurers which have issued primary mortgage
guaranty insurance policies with respect to the Mortgage Loans meet FNMA's or
FHLMC's standards or are acceptable to the Rating Agencies. In certain
circumstances, however, IndyMac does not require primary mortgage guaranty
insurance on mortgage loans with principal balances up to $500,000 that have
Loan-to-Value Ratios exceeding 80% but less than or equal to 95%. All residences
except cooperatives and certain high-rise condominium dwellings are eligible for
this program. Each qualifying mortgage loan will be made at an interest rate
that is higher than the rate would be if the Loan-to-Value Ratio was 80% or less
or if primary mortgage guaranty insurance was obtained. Under such
circumstances, the Certificateholders will not have the benefit of primary
mortgage guaranty insurance coverage.
 
     In determining whether a prospective borrower has sufficient monthly income
available (i) to meet the borrower's monthly obligation on the proposed mortgage
loan and (ii) to meet monthly housing expenses and other financial obligations
including the borrower's monthly obligations on the proposed mortgage loan,
IndyMac generally considers the ratio of such amounts to the proposed borrower's
acceptable stable monthly gross income. Such ratios vary depending on a number
of underwriting criteria, including Loan-to-Value Ratios, and are determined on
a loan-by-loan basis.
 
     IndyMac purchases loans which have been originated under one of three
documentation programs: the Full/Alternate Documentation Program, the Reduced
Documentation Program and the No Income/No Asset Program.
 
     Under the Full/Alternate Documentation Program, the prospective borrower's
employment, income and assets are verified through written or telephonic
communications. All loans may be submitted under the Full/Alternate
Documentation Program. The Full/Alternate Documentation Program also provides
for alternative methods of employment verification generally using W-2 forms or
pay stubs.
 
     Under the Reduced Documentation Program, more emphasis is placed on the
value and adequacy of the mortgaged property as collateral and other assets of
the borrower than on credit underwriting. Mortgage loans underwritten under the
Reduced Documentation Program are limited to borrowers with credit histories
that demonstrate an established ability to repay indebtedness in a timely
fashion. Under the Reduced Documentation Program, certain credit underwriting
documentation concerning income or income verification and/or employment
verification is waived. For certain loans submitted under the Reduced
Documentation Program with Loan-to-Value Ratios not exceeding 80%, income ratios
for the prospective borrower are not calculated. Income ratios will not have
been calculated for Mortgage Loans expected to constitute approximately 15.74%
of the Mortgage Loans in Loan Group 1, 16.02% of the Mortgage Loans in Loan
Group 2 and 19.79% of the Mortgage Loans in Loan Group 3, in each case, of the
aggregate Stated Principal Balance of the respective Loan Group as of the
Cut-off Date.
 
     Loans acquired under the Reduced Documentation Program include cash-out
refinance loans, super jumbos and mortgage loans secured by investor-owned
properties. Permitted maximum Loan-to-Value Ratios (including secondary
financing) under the Reduced Documentation Program, which range up to 90%, are
more restrictive than under the Full/Alternate Documentation Program.
 
     Under the No Income/No Asset Program, emphasis is placed on the value and
adequacy of the mortgaged property as collateral rather than on credit
underwriting and assets of the borrower. Mortgage Loans underwritten under the
No Income/No Asset Program are limited to borrowers with excellent credit
histories. Under the No Income/No Asset Program, credit underwriting
documentation concerning income, employment verification and asset verification
is waived and income ratios are not calculated.
 
REPRESENTATIONS BY SELLER; REPURCHASES, ETC.
 
     In the event of a breach of any representation or warranty in respect of a
Mortgage Loan that materially and adversely affects the interests of the
Certificateholders, the Seller will be obligated, in accordance with the
Agreement, to cure such breach, to repurchase such Mortgage Loan at the Purchase
Price or to substitute a qualified mortgage loan for such Mortgage Loan. See
'Mortgage Loan Program -- Representations by Sellers; Repurchases' in the
Prospectus. If, however, the substance of such breach constitutes fraud in the
origination of such Mortgage Loan and the Seller, at the time of such
origination and on the Closing Date, had no actual
 
                                      S-21
 

<PAGE>
<PAGE>

knowledge of such fraud, the Seller shall have no obligation to cure such breach
or to repurchase or substitute for such Mortgage Loan.
 
                          SERVICING OF MORTGAGE LOANS
 
THE MASTER SERVICER
 
     IndyMac will act as Master Servicer. The principal executive offices of
IndyMac are located at 155 North Lake Avenue, Pasadena, California 91101.
 
     The Master Servicer will be responsible for servicing the Mortgage Loans in
accordance with the terms set forth in the Agreement employing that degree of
skill and care which it employs in servicing mortgage loans comparable to the
Mortgage Loans serviced by the Master Servicer for itself or others. The Master
Servicer intends to perform its servicing obligations under the Agreement
through one or more Seller/Servicers. Notwithstanding any such servicing
arrangement, the Master Servicer will remain liable for its servicing duties and
obligations under the Agreement as if the Master Servicer alone were servicing
the Mortgage Loans.
 
SERVICING AND COLLECTION PROCEDURES
 
     IndyMac has entered into contracts (each a 'Seller/Servicer Contract') with
Seller/Servicers to sell mortgage loans to IndyMac and, in most cases, to
perform, as independent contractors, servicing functions for IndyMac subject to
its supervision. Such servicing functions include collection and remittance of
principal and interest payments, administration of mortgage escrow accounts,
collection of certain insurance claims and, if necessary, foreclosure. IndyMac
may permit Seller/Servicers to contract with subservicers to perform some or all
of the Seller/Servicer's servicing duties, but the Seller/Servicer will not
thereby be released from its obligations under the Seller/Servicer Contract.
IndyMac also may enter into servicing contracts directly with an affiliate of a
Seller/Servicer or permit a Seller/Servicer to transfer its servicing rights and
obligations to a third party. In such instances, the affiliate or third party,
as the case may be, will perform servicing functions comparable to those
normally performed by the Seller/Servicer as described above, and the
Seller/Servicer will not be obligated to perform such servicing functions. When
used herein with respect to servicing obligations, the term Seller/Servicer
includes any such affiliate or third party. IndyMac may perform certain
supervisory functions with respect to servicing by the Seller/Servicers directly
or through an agent or independent contractor and will be responsible for
administering and servicing the Mortgage Loans pursuant to the Agreement. On or
before the Closing Date, IndyMac will establish one or more accounts (the
'Collection Account') into which each Seller/Servicer will remit collections on
the mortgage loans serviced by it (net of its related servicing compensation).
For purposes of the Agreement, IndyMac, as Master Servicer, will be deemed to
have received any amounts with respect to the Mortgage Loans that are received
by a Seller/Servicer regardless of whether such amounts are remitted by the
Seller/Servicer to IndyMac. IndyMac has reserved the right to remove the
Seller/Servicer servicing any Mortgage Loan at any time and will exercise that
right if IndyMac considers such removal to be in the best interest of the
Certificateholders. In the event that IndyMac removes a Seller/Servicer, IndyMac
will continue to be responsible for servicing the related Mortgage Loans.
 
     With respect to Loan Group 1, one Seller/Servicer will be servicing more
than 10% of the principal balance of the Mortgage Loans. It is expected that
this Seller/Servicer will be servicing approximately 75.19% of the Stated
Principal Balance of the Mortgage Loans in Loan Group 1 as of the Cut-off Date.
With respect to Loan Group 2, two Seller/Servicers will be servicing more than
10% of the principal balance of the Mortgage Loans. It is expected that these
Seller/Servicers will be servicing approximately 53.14% and 12.23%,
respectively, of the Stated Principal Balance of the Mortgage Loans in Loan
Group 2 as of the Cut-off Date. With respect to Loan Group 3, two
Seller/Servicers will be servicing more than 10% of the principal balance of the
Mortgage Loans. It is expected that these Seller/Servicers will be servicing
approximately 59.55% and 10.14%, respectively, of the Stated Principal Balance
of the Mortgage Loans in Loan Group 3 as of the Cut-off Date.
 
     In connection with the servicing of defaulted Mortgage Loans, the Master
Servicer may perform certain default management and other similar services
(including, but not limited to, appraisal services) and may act as a broker in
the sale of mortgaged properties related to such Mortgage Loans. The Master
Servicer shall be entitled to reasonable compensation for providing such
services.
 
FORECLOSURE AND DELINQUENCY EXPERIENCE
 
     The following table summarizes the delinquency and foreclosure experience,
respectively, as of December 31, 1996, December 31, 1997 and June 30, 1998 on
approximately $11.1 billion, $12.3 billion and $13.9 billion, respectively, in
outstanding principal balance of conventional mortgage loans master serviced by
 
                                      S-22

<PAGE>

the Master Servicer. IndyMac commenced master servicing conventional mortgage
loans during April 1993. The delinquency and foreclosure percentages may be
affected by the size and relative lack of seasoning of the servicing portfolio
because many of such mortgage loans were not outstanding long enough to give
rise to some or all of the indicated periods of delinquency. Accordingly, the
information should not be considered as a basis for assessing the likelihood,
amount or severity of delinquency or losses on the Mortgage Loans, and no
assurances can be given that the foreclosure and delinquency experience
presented in the table below will be indicative of such experience on the
Mortgage Loans in the future:

(1)  As a percentage of the total number of loans master serviced.
 
     There can be no assurance that factors beyond the Master Servicer's
control, such as national or local economic conditions or downturns in the real
estate markets of its lending areas, will not result in increased rates of
delinquencies and foreclosure losses in the future. For example, over the last
several years there has been a general deterioration of the real estate market
and weakening of the economy in several regions of the country. The general
deterioration of the real estate market has been reflected in increases in
delinquencies of loans secured by real estate, slower absorption rates of real
estate into the market and lower sales prices for real estate. The general
weakening of the economy has been reflected in decreases in the financial
strength of borrowers and decreases in the value of collateral serving as
collateral for loans. If the real estate market and economy continue to decline,
the Master Servicer may experience an increase in delinquencies on the loans it
services and higher net losses on liquidated loans.
 
SERVICING COMPENSATION AND PAYMENT OF EXPENSES
 
     The Expense Fees with respect to each of the respective Loan Groups are
payable out of the interest payments on each Mortgage Loan in the related Loan
Group. The Expense Fees will vary from Mortgage Loan to Mortgage Loan within a
Loan Group. The rate at which the Expense Fees accrue (the 'Expense Fee Rate')
is expected to range from 0.384% to 0.884% with respect to Loan Group 1 and is
expected to be 0.384% per annum with respect to Loan Group 2 and Loan Group 3,
in each case of the Stated Principal Balance of the related Mortgage Loan. As of
the Cut-off Date, the weighted average Expense Fee Rate is expected to equal
approximately 0.385% with respect to Loan Group 1 and 0.384% with respect to
Loan Group 2 and Loan Group 3. The Expense Fees consist of (a) master servicing
compensation payable to the Master Servicer in respect of its master servicing
activities (the 'Master Servicing Fee'), (b) servicing compensation payable to
the Seller/Servicers in respect of their servicing activities (the 'Servicing
Fee') and (c) fees payable to the Trustee in respect of its activities as
trustee under the Agreement. The Master Servicing Fee will be 0.125% per annum
of the Stated Principal Balance of each Mortgage Loan. The Servicing Fee payable
to each Seller/Servicer will vary from Mortgage Loan to Mortgage Loan and is
expected to range from 0.250% to 0.750% with respect to Loan Group 1 and is
expected to be 0.250% per annum with respect to Mortgage Loans in Loan Group 2
and Loan Group 3, in each case of the Stated Principal Balance of the related
Mortgage Loan serviced by such Seller/Servicer. The Master Servicer is obligated
to pay certain ongoing expenses associated with the Trust Fund and incurred by
the Master Servicer in connection with its responsibilities under the Agreement
and such amounts will be paid by the Master Servicer out of the Master Servicing
Fee. The amount of the Master Servicing Fee is subject to adjustment with
respect to prepaid Mortgage Loans, as described herein under ' -- Adjustment to
Master Servicing Fee in Connection with Certain Prepaid Mortgage Loans.' The
Master

<PAGE>

Servicer or the related Seller/Servicer will also be entitled to receive late
payment fees, assumption fees and other similar charges. The Master Servicer
will be entitled to receive all reinvestment income earned on amounts on deposit
in the Collection Account and the Distribution Account. The Adjusted Net
Mortgage Rate of a Mortgage Loan is the Mortgage Rate thereof minus the related
Expense Fee Rate.
 
     The Master Servicer will be entitled to reimbursement for certain expenses
incurred by it in connection with any defaulted Mortgage Loan as to which it has
determined that all recoverable liquidation and insurance proceeds have been
received (a 'Liquidated Mortgage Loan'), 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).
 
ADJUSTMENT TO MASTER SERVICING FEE IN CONNECTION WITH CERTAIN PREPAID MORTGAGE
LOANS
 
     When a borrower prepays a Mortgage Loan between Due Dates, the borrower is
required to pay interest on the amount prepaid only to the date of prepayment
and not thereafter. Principal prepayments by borrowers received during a
calendar month will be distributed to Certificateholders on the Distribution
Date in the month following the month of receipt. Pursuant to the Agreement, the
aggregate amount of the Master Servicing Fee for any month will be reduced by an
amount with respect to each such prepaid Mortgage Loan sufficient to pass
through to Certificateholders the full amount of interest to which they would be
entitled in respect of such Mortgage Loan on the related Distribution Date. If
shortfalls in interest as a result of prepayments in any month exceed the
aggregate amount of the Master Servicing Fee for such month, the amount of
interest available to be distributed to Certificateholders will be reduced by
the amount of such excess. See 'Description of the Certificates -- Interest'
herein.
 
ADVANCES
 
     Subject to the following limitations, the Master Servicer will be required
to advance prior to each Distribution Date, from its own funds, funds advanced
by the related Seller/Servicers or amounts received with respect to the Mortgage
Loans that do not constitute Available Funds for such Distribution Date, an
amount equal to the aggregate of payments of principal of and interest on the
Mortgage Loans (net of the Master Servicing Fee and the applicable Servicing Fee
with respect to the related Mortgage Loans) which were due on the related Due
Date and which were delinquent on the related Determination Date, together with
an amount equivalent to interest on each Mortgage Loan as to which the related
Mortgaged Property has been acquired by the Trust Fund through foreclosure or
deed-in-lieu of foreclosure ('REO Property') (any such advance, an 'Advance').
 
     Advances are intended to maintain a regular flow of scheduled interest and
principal payments on the Certificates rather than to guarantee or insure
against losses. The Master Servicer is obligated to make Advances with respect
to delinquent payments of principal of or interest on each Mortgage Loan to the
extent that such Advances are, in its reasonable judgment, recoverable from
future payments and collections or insurance payments or proceeds of liquidation
of the related Mortgage Loan. If the Master Servicer determines on any
Determination Date to make an Advance, such Advance will be included with the
distribution to Certificateholders on the related Distribution Date. As
described under 'The Pooling and Servicing Agreement -- Events of Default,' any
failure by the Master Servicer to make a deposit in the Certificate Account as
required under the Agreement, including any failure to make an Advance, will
constitute an Event of Default under the Agreement if such failure remains
unremedied for five days after written notice thereof. If the Master Servicer is
terminated as a result of the occurrence of an Event of Default, the Trustee or
the successor master servicer will be obligated to make any such Advance, in
accordance with the terms of the Agreement.
 
SPECIAL SERVICING AGREEMENTS
 
     The Pooling and Servicing Agreement may permit the Master Servicer to enter
into a special servicing agreement with an unaffiliated holder of one or more
Classes of Subordinated Certificates or of a class of securities representing
interests in one or more Classes of Subordinated Certificates. Pursuant to such
an agreement, such holder may instruct the Master Servicer to commence or delay
foreclosure proceedings with respect to delinquent Mortgage Loans. Such
commencement or delay at such holder's direction will be taken by the Master
Servicer only after such holder deposits a specified amount of cash with the
Master Servicer. Such cash will be available for distribution to
Certificateholders if Liquidation Proceeds are less than they otherwise may have
been had the Master Servicer acted pursuant to its normal servicing procedures.

the 'Senior Certificates') and the Class B-1, Class B-2, Class B-3, Class B-4,
Class B-5 and Class B-6 Certificates (collectively, the 'Subordinated
Certificates'). The Senior Certificates and the Subordinated Certificates are
collectively referred to herein as the 'Certificates.' Only the Senior
Certificates and Class B-1, Class B-2 and Class B-3 Certificates (collectively,
the 'Offered Certificates') are offered hereby. The Classes of Offered
Certificates will have the respective initial Class Certificate Balances or
initial Notional Amounts (subject to the permitted variance) and Pass-Through
Rates set forth on the cover page hereof or as described herein.
 
     The Class Certificate Balance of any Class of Certificates as of any
Distribution Date is the initial Class Certificate Balance thereof reduced by
the sum of (i) all amounts previously distributed to holders of Certificates of
such Class as payments of principal, (ii) the amount of Realized Losses
(including Excess Losses) allocated to such Class and (iii) in the case of any
Class of Subordinated Certificates, any amounts allocated to such Class in
reduction of its Class Certificate Balance in respect of payments of Class PO
Deferred Amounts, as described below under ' -- Allocation of Losses.' In
addition, the Class Certificate Balance of the Class of Subordinated
Certificates then outstanding with the highest numerical Class designation will
be reduced if and to the extent that the aggregate of the Class Certificate
Balances of all Classes of Certificates, following all distributions and the
allocation of Realized Losses on a Distribution Date, exceeds the Pool Principal
Balance as of the Due Date occurring in the month of such Distribution Date. The
Notional Amount Certificates do not have a principal balance and are not
entitled to any distributions in respect of principal of the Mortgage Loans.
 
     The Notional Amount of each Class of Notional Amount Certificates for any
Distribution Date will be equal to the aggregate of the Stated Principal
Balances of the Non-Discount Mortgage Loans in the related Loan Group with
respect to such Distribution Date. The initial Notional Amount of each Class of
Notional Amount Certificates will be equal to the aggregate of the Stated
Principal Balances of the Mortgage Loans in the related Loan Group as of the
Cut-off Date.
 
     The Loan Group 1 Senior Certificates will have an initial aggregate
principal balance of approximately $374,064,399 and will evidence in the
aggregate an initial beneficial ownership interest of approximately 93.50% in
the Mortgage Loans in Loan Group 1. The Loan Group 2 Senior Certificates will
have an initial aggregate principal balance of approximately $280,623,287 and
will evidence in the aggregate an initial beneficial ownership interest of
approximately 93.50% in the Mortgage Loans in Loan Group 2. The Loan Group 3
Senior Certificates will have an initial aggregate principal balance of
approximately $140,321,737 and will evidence in the aggregate an initial
beneficial ownership interest of approximately 93.50% in the Mortgage Loans in
Loan Group 3. The Class B-1, Class B-2, Class B-3, Class B-4, Class B-5 and
Class B-6 Certificates will each evidence in the aggregate an initial beneficial
ownership interest of approximately 3.05%, 1.40%, 0.80%, 0.55%, 0.25% and 0.45%,
respectively, in the Trust Fund.
 
     The Book-Entry Certificates will be issuable in book-entry form only. The
Physical Certificates will be issued in fully registered certificated form. The
Physical Certificates offered hereby, other than the Class A-R Certificates,
will be issued in minimum denominations of $25,000 and integral multiples of
$1,000 in excess thereof. A single Certificate of each Class may be issued in an
amount different than described above. The Class A-R Certificates will be issued
as a single certificate with a dollar denomination of $100.

BOOK-ENTRY CERTIFICATES
 
     Each Class of Book-Entry Certificates will be issued in one or more
certificates which equal the aggregate initial Class Certificate Balance of each
such Class of Certificates and which will be held by a nominee of The Depository
Trust Company ('DTC'). Beneficial interests in the Book-Entry Certificates will
be held indirectly by investors through the book-entry facilities of DTC, as
described herein. Investors may hold such beneficial interests in the Book-Entry
Certificates in minimum denominations representing an original principal amount
of $25,000 and integral multiples of $1,000 in excess thereof. One investor of
each Class of Book-Entry Certificates may hold a beneficial interest therein
that is not an integral multiple of $1,000. The Depositor has been informed by
DTC that its nominee will be CEDE & Co. ('CEDE'). Accordingly, CEDE is expected
to be the holder of record of the Book-Entry Certificates. Except as described
in 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 the Book-Entry Certificates will be CEDE, as
nominee of DTC. Beneficial owners of the Book-Entry Certificates will not be
Certificateholders, as that term is used in the Agreement. Beneficial owners are
only permitted to exercise the rights of Certificateholders indirectly through
Financial Intermediaries and DTC. Monthly and annual reports on the Trust Fund
provided to CEDE, as nominee of DTC, may be made available to beneficial owners
upon request, in accordance with the rules, regulations and procedures creating
and affecting DTC, and to the Financial Intermediaries to whose DTC accounts the
Book-Entry Certificates of such beneficial owners are credited.
 
     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 Trustee in writing that DTC is no longer willing,
qualified or able to discharge properly its responsibilities as nominee and
depository with respect to the Book-Entry Certificates and the Depositor or the
Trustee is unable to locate a qualified successor; (b) the Depositor, at its
sole option, elects to terminate the book-entry system through DTC; or (c) after
the occurrence of an Event of Default, beneficial owners of Certificates
representing not less than 51% of the aggregate Voting Rights evidenced by each
Class of Certificates issued as Book-Entry Certificates advise the Trustee and
DTC through the Financial Intermediaries in writing that the continuation of a
book-entry system through DTC (or a successor thereto) is no longer in the best
interests of the beneficial owners. For a description of the procedures
generally applicable to the Book-Entry Certificates, see 'Description of the
Securities -- Book-Entry Registration of Securities' in the Prospectus.
 
DETERMINATION OF LIBOR
 
     The LIBOR Certificates will bear interest during their initial Interest
Accrual Period at the applicable initial Pass-Through Rate set forth in the
table under ' -- Interest' below, and during each Interest Accrual Period
thereafter at the applicable rate determined as described in the table under
' -- Interest' below.
 
     LIBOR applicable to an Interest Accrual Period will be determined on the
second business day prior to the commencement of such Interest Accrual Period (a
'LIBOR Determination Date'). On each LIBOR Determination Date for the LIBOR
Certificates, the Trustee, as Calculation Agent, will establish LIBOR for the
related Interest Accrual Period on the basis of the British Bankers' Association
('BBA') 'Interest Settlement Rate' for one-month deposits in U.S. dollars as
found on Telerate Page 3750 as of 11:00 a.m. London time on each LIBOR
Determination Date. Interest Settlement Rates currently are based on rates
quoted by sixteen BBA designated banks as being, in the view of such banks, the
offered rate at which deposits are being quoted to prime banks in the London
interbank market. Such Interest Settlement Rates are calculated by eliminating
the four highest rates and the four lowest rates, averaging the eight remaining
rates, carrying the result (expressed as a percentage) out to six decimal
places, and rounding to five decimal places. 'Telerate Page 3750' means the
display page currently so designated on the Dow Jones Markets (formerly Telerate
Service) (or such other page as may replace that page on that service for the
purpose of displaying comparable rates or prices.)
 
     If on any LIBOR Determination Date, the Calculation Agent is unable to
calculate LIBOR in accordance with the method set forth in the immediately
preceding paragraph, LIBOR for the next Interest Accrual Period shall be
calculated in accordance with the method described in the Prospectus under
'Description of the Certificates -- Indices Applicable to Floating Rate and
Inverse Floating Rate Classes -- LIBOR.'
 
                                      S-26
 

<PAGE>
<PAGE>

     If on the initial LIBOR Determination Date, the Calculation Agent is
required but unable to determine LIBOR in the manner provided in the Prospectus,
LIBOR for the next Interest Accrual Period will be 5.65625%.
 
PAYMENTS ON MORTGAGE LOANS; ACCOUNTS
 
     On or prior to the Closing Date, the Trustee will establish an account (the
'Distribution Account'), which shall be maintained with the Trustee in trust for
the benefit of the Certificateholders. On or prior to the business day
immediately preceding each Distribution Date, the Master Servicer will withdraw
from the Certificate Account the amount of Available Funds for each Loan Group
for such Distribution Date and will deposit such Available Funds in the
Distribution Account. Funds credited to the Certificate Account or the
Distribution Account may be invested for the benefit and at the risk of the
Master Servicer in Permitted Investments, as defined in the Agreement, that are
scheduled to mature on or prior to the business day preceding the next
Distribution Date.
 
DISTRIBUTIONS
 
     Distributions on the Certificates will be made by the Trustee on the 25th
day of each month, or if such day is not a business day, on the first business
day thereafter, commencing in August 1998 (each, a 'Distribution Date'), to the
persons in whose names such Certificates are registered at the close of business
on the last business day of the month preceding the month of such Distribution
Date (the 'Record Date').
 
     Distributions on each Distribution Date will be made by check mailed to the
address of the person entitled thereto as it appears on the applicable
certificate register or, in the case of a Certificateholder who holds 100% of a
Class of Certificates or who holds a Notional Amount Certificate or who holds
Certificates with an aggregate initial Certificate Balance of $1,000,000 or more
and who has so notified the Trustee in writing in accordance with the Agreement,
by wire transfer in immediately available funds to the account of such
Certificateholder at a bank or other depository institution having appropriate
wire transfer facilities; provided, however, that the final distribution in
retirement of the Certificates will be made only upon presentment and surrender
of such Certificates at the Corporate Trust Office of the Trustee.
 
PRIORITY OF DISTRIBUTIONS AMONG CERTIFICATES
 
     As more fully described herein, on each Distribution Date distributions on
the Loan Group 1 Senior Certificates, the Loan Group 2 Senior Certificates and
the Loan Group 3 Senior Certificates will be, except as provided below, based on
the Available Funds of the related Loan Group for such Distribution Date, and
distributions on the Subordinated Certificates will be based on any remaining
Available Funds of all Loan Groups for such Distribution Date, in each case
after giving effect to distributions on all Classes of Senior Certificates and
payments in respect of Class PO Deferred Amounts, and will be made in the
following order of priority: (i) to interest on each related interest-bearing
Class or Classes of Senior Certificates; (ii) to principal of the related Class
or Classes of Senior Certificates then entitled to receive distributions of
principal, in the order and subject to the priorities set forth herein under
' -- Principal' in each case in an aggregate amount up to the maximum amount of
principal to be distributed on such Classes on such Distribution Date; (iii) to
any related Class PO Deferred Amounts with respect to the applicable Class PO
Certificates, but only from related Available Funds that would otherwise be
distributable on such Distribution Date as principal of the Subordinated
Certificates; and (iv) to interest on and then principal of each Class of
Subordinated Certificates, in the order of their numerical Class designations,
beginning with the Class B-1 Certificates, subject to certain limitations set
forth herein under ' -- Principal.'
 
     Notwithstanding the foregoing, if on any Distribution Date (i) Available
Funds for a Loan Group is insufficient to make (x) distributions of interest and
principal on the Senior Certificates of the related Senior Certificate Group or
(y) payments in respect of the related Class PO Deferred Amounts or (ii) the
aggregate Class Certificate Balance of the Senior Certificates (other than the
related Class PO Certificates) of a Senior Certificate Group exceeds the
aggregate Stated Principal Balance of the Mortgage Loans in the related Loan
Group (the 'Supported Distributions'), Available Funds from the other Loan
Groups after giving effect to all distributions on the Senior Certificate Groups
of such other Loan Groups and payments in respect of the related Class PO
Deferred Amounts will be available to make the Supported Distributions. Such
amounts will be applied in the order and priority and subject to the limitations
described above.

<PAGE>

     'Available Funds' with respect to any Distribution Date and the Mortgage
Loans in a Loan Group will be equal to the sum of (i) all scheduled installments
of interest (net of the related Expense Fees relating to such Loan Group) and
principal due on the Due Date in the month in which such Distribution Date
occurs and received prior to the related Determination Date, together with any
Advances in respect thereof; (ii) all proceeds of any primary mortgage guaranty
insurance policies and any other insurance policies with respect to such
Mortgage Loans, to the extent such proceeds are not applied to the restoration
of the related Mortgaged Property or released to the Mortgagor in accordance
with the Master Servicer's normal servicing procedures (collectively, 'Insurance
Proceeds') and all other cash amounts received and retained in connection with
the liquidation of defaulted Mortgage Loans, by foreclosure or otherwise
('Liquidation Proceeds') during the month preceding the month of such
Distribution Date (in each case, net of unreimbursed expenses incurred in
connection with a liquidation or foreclosure and unreimbursed Advances, if any);
(iii) all partial or full prepayments received during the month preceding the
month of such Distribution Date; and (iv) amounts received with respect to such
Distribution Date as the Substitution Adjustment Amount or purchase price in
respect of a Deleted Mortgage Loan or a Mortgage Loan in such Loan Group
repurchased by the Seller or the Master Servicer as of such Distribution Date,
reduced by amounts in reimbursement for Advances previously made and other
amounts as to which the Master Servicer is entitled to be reimbursed pursuant to
the Agreement.
 
INTEREST
 
     The Pass-Through Rate for each Class of Offered Certificates for each
Distribution Date (the 'Pass-Through Rate') is as set forth or described on the
cover hereof.
 
     The Pass Through Rate for the Class X-1 Certificates for any Distribution
Date will be equal to the excess of (a) the weighted average of the Adjusted Net
Mortgage Rates of the Non-Discount Mortgage Loans in Loan Group 1 over (b) 6.75%
per annum. The Pass Through Rate for the Class X-2 Certificates for any
Distribution Date will be equal to the excess of (a) the weighted average of the
Adjusted Net Mortgage Rates of the Non-Discount Mortgage Loans in Loan Group 2
over (b) 6.75% per annum. The Pass Through Rate for the Class X-3 Certificates
for any Distribution Date will be equal to the excess of (a) the weighted
average of the Adjusted Net Mortgage Rates of the Non-Discount Mortgage Loans in
Loan Group 3 over (b) 6.75% per annum. The Pass-Through Rates for the Class X-1,
Class X-2 and Class X-3 Certificates for the first Distribution Date are
expected to be approximately 0.926% per annum, 0.898% per annum and 0.942% per
annum, respectively.
 
     Each of the LIBOR Certificates will bear interest during its initial
Interest Accrual Period at the initial Pass-Through Rate set forth below, and
will bear interest during each Interest Accrual Period thereafter, subject to
the applicable Maximum and Minimum Pass-Through Rates, at the per annum rate
determined by reference to LIBOR as described below:

     On each Distribution Date, to the extent of funds available therefor, each
interest-bearing Class of Certificates will be entitled to receive an amount
allocable to interest (as to each such Class, the 'Interest Distribution
Amount') with respect to the related Interest Accrual Period. The Interest
Distribution Amount for any such Class will be equal to the sum of (i) interest
at the applicable Pass-Through Rate on the related Class Certificate Balance or
Notional Amount, as the case may be, and (ii) the sum of the amounts, if any, by
which the amount described in clause (i) above on each prior Distribution Date
exceeded the amount actually distributed as interest on such prior Distribution
Dates and not subsequently distributed ('Unpaid Interest Amounts'). The Class PO
Certificates are Principal Only Certificates and will not bear interest.
 
     With respect to each Distribution Date, the 'Interest Accrual Period' for
the Delay Certificates will be the calendar month preceding the month of such
Distribution Date. With respect to each Distribution Date, the 'Interest Accrual
Period' for the Non-Delay Certificates is the one-month period commencing on the
25th day of the month preceding the month in which such Distribution Date occurs
and ending on the 24th day of the month in which such Distribution Date occurs.
The initial Interest Accrual Period for the LIBOR Certificates will commence on
July 25, 1998.

     The interest entitlement described above for each Class of Certificates
will be reduced by the amount of 'Net Interest Shortfalls' experienced by (a)
the related Loan Group, with respect to the Senior Certificates (other than the
Class PO Certificates) and (b) all Loan Groups, with respect to the Subordinated
Certificates, in each case for such Distribution Date. With respect to any
Distribution Date, the 'Net Interest Shortfall' for a Loan Group is equal to the
sum of (i) the amount of interest which would otherwise have been received with
respect to any Mortgage Loan in such Loan Group that was the subject of (x) a
Relief Act Reduction or (y) a Special Hazard Loss, Fraud Loss, Debt Service
Reduction or Deficient Valuation, after the exhaustion of the respective amounts
of coverage provided by the Subordinated Certificates for such types of losses
and (ii) any Net Prepayment Interest Shortfalls. Net Interest Shortfalls for a
Loan Group on any Distribution Date will be allocated pro rata among all
interest-bearing Class or Classes of the related Senior Certificates and all
Classes of the Subordinated Certificates entitled to receive distributions of
interest on such Distribution Date, based on the amount of interest each such
Class of Certificates would otherwise be entitled to receive (or, in the case of
the Subordinated Certificates, deemed to be entitled to receive, as described
more fully below) from Available Funds for such Loan Group on such Distribution
Date before taking into account any reduction in such amounts resulting from
such Net Interest Shortfalls.
 
     For purposes of allocating Net Interest Shortfalls for a Loan Group to the
Subordinated Certificates on any Distribution Date, the amount of interest each
Class of Subordinated Certificates would otherwise deemed to be entitled to
receive from Available Funds for such Loan Group on such Distribution Date will
equal an amount of interest at the Pass-Through Rate on a balance equal to such
Class' pro rata share (based on the respective Class Certificate Balances) of
the Subordinated Percentage for such Distribution Date relating to such Loan
Group of the aggregate of the applicable Non-PO Percentage of the Stated
Principal Balance of each Mortgage Loan in such Loan Group as of the Due Date
occurring in the month of such Distribution Date; provided, however, on any
Distribution Date after the Senior Depletion Date for a Senior Certificate
Group, Net Interest Shortfalls for the related Loan Group will be allocated to
the Classes of Subordinated Certificates based on the amount of interest each
such Class of Subordinated Certificates would otherwise be entitled to receive
on such Distribution Date after the allocation with respect to the other Loan
Groups as provided above under ' -- Priority of Distributions Among
Certificates.'
 
     A 'Relief Act Reduction' is a reduction in the amount of monthly interest
payment on a Mortgage Loan pursuant to the Soldiers' and Sailors' Civil Relief
Act of 1940. See 'Certain Legal Aspects of Mortgage Loans -- Soldiers' and
Sailors' Civil Relief Act' in the Prospectus. With respect to any Distribution
Date, the 'Net Prepayment Interest Shortfall' for a Loan Group is the amount by
which the aggregate of Prepayment Interest Shortfalls experienced by Mortgage
Loans in such Loan Group during the calendar month preceding the month of such
Distribution Date exceeds the Master Servicing Fee for such period. A
'Prepayment Interest Shortfall' is the amount by which interest paid by a
borrower in connection with a prepayment of principal on a Mortgage Loan is less
than one month's interest at the related Mortgage Rate (net of the related
Master Servicing Fee) on the Stated Principal Balance of such Mortgage Loan.
 
     Accrued interest to be distributed on any Distribution Date will be
calculated, in the case of each Class of Certificates on the basis of the
related Class Certificate Balance or Notional Amount, as applicable, immediately
prior to such Distribution Date. Interest will be calculated and payable on the
basis of a 360-day year divided into twelve 30-day months.
 
     In the event that, on a particular Distribution Date, Available Funds for a
Loan Group and any amounts available to make Supported Distributions applied in
the order described above under ' -- Priority of Distributions Among
Certificates' are not sufficient to make a full distribution of the interest
entitlement on the Senior Certificates in a Senior Certificate Group or on the
Subordinated Certificates, interest will be distributed on each Class of Senior
Certificates in such Senior Certificate Group and each Class of Subordinated
Certificates of equal priority based on the amount of interest each such Class
would otherwise have been entitled to receive in the absence of such shortfall.
Any such unpaid amount will be carried forward and added to the amount holders
of each such Class of Certificates will be entitled to receive on the next
Distribution Date. Such a shortfall could occur, for example, if losses realized
on the Mortgage Loans for the related Loan Group, with respect to the Senior
Certificates, or all of the Mortgage Loans with respect to the Subordinated
Certificates, were exceptionally high or were concentrated in a particular
month. Any such unpaid amount will not bear interest.

PRINCIPAL
 
     General.  All payments and other amounts received in respect of principal
of the Mortgage Loans of a Loan Group will be allocated between (i) the Class or
Classes of the related Class A Certificates and the Subordinated Certificates
and (ii) the applicable Class PO Certificates in each case based on the
applicable Non-PO Percentage and the applicable PO Percentage respectively, of
such amounts.
 
     The Non-PO Percentage with respect to any Mortgage Loan with an Adjusted
Net Mortgage Rate ('ANMR') less than 6.75% (each such Mortgage Loan, a 'Discount
Mortgage Loan') will be equal to ANMR [div] 6.75%. The Non-PO Percentage with
respect to any Mortgage Loan with an Adjusted Net Mortgage Rate equal to or
greater than 6.75% (each such Mortgage Loan, a 'Non-Discount Mortgage Loan')
will be 100%. The PO Percentage with respect to any Discount Mortgage Loan will
be equal to (6.75%  - ANMR) [div] 6.75%. The PO Percentage with respect to any
Non-Discount Mortgage Loan will be 0%.
 
     Non-PO Formula Principal Amount. On each Distribution Date, the Non-PO
Formula Principal Amount for each Loan Group will be distributed as principal of
the Senior Certificates of such Loan Group (other than the related Notional
Amount Certificates and Class PO Certificates) and the Subordinated
Certificates, to the extent of the amount available from Available Funds for
such Loan Group for the distribution of principal on such respective
Certificates, as described below.
 
     The Non-PO Formula Principal Amount for any Distribution Date and Loan
Group will equal the sum of the applicable Non-PO Percentage of (a) all monthly
payments of principal due on each Mortgage Loan in such Loan Group on the
related Due Date, (b) the principal portion of the purchase price of each
Mortgage Loan in such Loan Group that was repurchased by the Seller or another
person pursuant to the Agreement as of such Distribution Date, (c) the
Substitution Adjustment Amount in connection with any Deleted Mortgage Loan in
such Loan Group received with respect to such Distribution Date, (d) any
Insurance Proceeds or Liquidation Proceeds allocable to recoveries of principal
of Mortgage Loans in such Loan Group that are not yet Liquidated Mortgage Loans
received during the calendar month preceding the month of such Distribution
Date, (e) with respect to each Mortgage Loan in such Loan Group that became a
Liquidated Mortgage Loan during the calendar month preceding the month of such
Distribution Date, the amount of the Liquidation Proceeds allocable to principal
received with respect to such Mortgage Loan and (f) all partial and full
principal prepayments by borrowers received during the calendar month preceding
the month of such Distribution Date with respect to Mortgage Loans in such Loan
Group.
 
     Components. Solely for purposes of allocating distributions of principal,
each of the Class II-A-4, Class II-A-7 and Class II-A-8 Certificates will be
comprised of multiple payment components having the related designations,
initial Component Balances and Pass-Through Rates set forth below:

     The 'Component Balance' with respect to any Component as of any
Distribution Date is the initial Component Balance thereof on the Closing Date,
less all amounts applied and losses allocated in reduction of the principal
balance of such Component on previous Distribution Dates.
 
     The Class Certificate Balance of each of the Class II-A-4, Class II-A-7 and
Class II-A-8 Certificates will be equal to the aggregate of the Component
Balances of the Components of such Class. The Components comprising a Class of
Certificates will not be separately transferable from such Class of
Certificates.
 
     Senior Principal Distribution Amount.  On each Distribution Date, prior to
the Senior Credit Support Depletion Date, the Senior Certificates of a Senior
Certificate Group (other than the related Class PO Certificates) will be
entitled to receive as principal from Available Funds applied in the order

     Group I Priority Amount for any Distribution Date will equal the sum of
(i) the product of (A) Scheduled Principal Distribution Amounts for Loan Group
1, (B) the Shift Percentage and (C) the Group I Priority Percentage and (ii) the
product of (A) Unscheduled Principal Distribution Amounts for Loan Group 1, (B)
the Prepayment Shift Percentage and (C) the Group I Priority Percentage.
 
     Group I Priority Percentage for any Distribution Date will equal the lesser
of (x) a fraction, the numerator of which is equal to the sum of (i) the
aggregate Class Certificate Balances of the Class I-A-10, Class I-A-11 and
Class I-A-12 Certificates immediately prior to such Distribution Date and (ii)
an amount equal to $33,333,000, and the denominator of which is equal to the sum
of the applicable Non-PO Percentage of the Stated Principal Balance of each
Mortgage Loan in Loan Group 1 and (y) 100%.
 
     Group II Priority Amount for any Distribution Date will equal the sum of
(i) the product of (A) Scheduled Principal Distribution Amounts for Loan Group
2, (B) the Shift Percentage and (C) the Group II Priority Percentage and (ii)
the product of (A) Unscheduled Principal Distribution Amounts for Loan Group 2,
(B) the Prepayment Shift Percentage and (C) the Group II Priority Percentage.
 
     Group II Priority Percentage for any Distribution Date will equal a
fraction, the numerator of which is equal to the aggregate of the Class
Certificate Balances of the Class II-A-1 and Class II-A-5 Certificates and the
Component Balances of the Class II-A-8a and Class II-A-4a Components immediately
prior to such Distribution Date and the denominator of which is equal to the sum
of the applicable Non-PO Percentage of the Stated Principal Balance of each
Mortgage Loan in Loan Group 2.
 
     Scheduled Principal Distribution Amounts for any Distribution Date and Loan
Group will equal the sum of the amounts described in clauses (i)(a), (i)(b),
(i)(c) and (i)(d) of the definition of Non-PO Formula Principal Distribution
Amount with respect to such Loan Group.
 
     Unscheduled Principal Distribution Amounts for any Distribution Date and
Loan Group will equal the sum of (i) with respect to each Mortgage Loan in such
Loan Group that became a Liquidated Mortgage Loan during the calendar month
preceding the month of such Distribution Date, the applicable Non-PO Percentage
of the Liquidation Proceeds allocable to principal received with respect to such
Mortgage Loan and (ii) the applicable Non-PO Percentage of all partial and full
principal prepayments by borrowers received during the calendar month preceding
the month of such Distribution Date with respect to the Mortgage Loans in such
Loan Group.
 
     Shift Percentage for any Distribution Date occurring during the five years
beginning on the first Distribution Date will equal 0%. Thereafter, the Shift
Percentage for any Distribution Date occurring on or after the fifth anniversary
of the first Distribution Date will equal 100%.
 
     Prepayment Shift Percentage for any Distribution Date occurring during the
five years beginning on the first Distribution Date will equal 0%. Thereafter,

occurring on or after the fifth anniversary of the first Distribution Date will
be as follows: for any Distribution Date in the first year thereafter, 30%; for
any Distribution Date in the second year thereafter, 40%; for any Distribution
Date in the third year thereafter, 60%; for any Distribution Date in the fourth
year thereafter, 80%; and for any Distribution Date thereafter, 100%.
 
     Notwithstanding the foregoing, on each Distribution Date on and after the
Senior Credit Support Depletion Date, the Senior Principal Distribution Amount
for each Loan Group will be distributed, concurrently, as principal of the
Classes of the related Senior Certificate Group (other than the applicable Class
PO Certificates) in each case pro rata, in accordance with their respective
Class Certificate Balances immediately prior to such Distribution Date.
 
     The Senior Credit Support Depletion Date is the date on which the Class
Certificate Balance of each Class of Subordinated Certificates has been reduced
to zero.
 
     The Senior Principal Distribution Amount for any Distribution Date and
Senior Certificate Group will equal the sum of (i) the related Senior Percentage
of the applicable Non-PO Percentage of all amounts described in clauses (a)
through (d) of the definition of 'Non-PO Formula Principal Amount', with respect
to such Loan Group for such Distribution Date, (ii) with respect to each
Mortgage Loan in the related Loan Group that became a Liquidated Mortgage Loan
during the calendar month preceding the month of such Distribution Date, the
lesser of (x) the related Senior Percentage of the applicable Non-PO Percentage
of the Stated Principal Balance of such Mortgage Loan and (y) either (A) the
related Senior Prepayment Percentage or (B) if an Excess Loss was sustained with
respect to such Liquidated Mortgage Loan during such preceding calendar month,
the related Senior Percentage of the applicable Non-PO Percentage of the amount
of the Liquidation Proceeds allocable to principal received with respect to such
Mortgage Loan, and (iii) the related Senior Prepayment Percentage of the
applicable Non-PO Percentage of amounts described in clause (f) of the
definition of 'Non-PO Formula Principal Amount', with respect to such Loan
Group, for such Distribution Date; provided, however, that if a Bankruptcy Loss
that is an Excess Loss is sustained with respect to a Mortgage Loan in the
related Loan Group that is not a Liquidated Mortgage Loan, the Senior Principal
Distribution Amount for such Senior Certificate Group will be reduced on the
related Distribution Date by the related Senior Percentage of the applicable
Non-PO Percentage of the principal portion of such Bankruptcy Loss.
Notwithstanding the foregoing, if a Senior Depletion Date occurs for one or more
Senior Certificate Groups, the 'Senior Principal Distribution Amount' for the
remaining Senior Certificate Group(s) will include the Non-PO Formula Principal
Amount for the Loan Group for which the Senior Depletion Date occurred;
provided, however, that if there are two remaining Senior Certificate Groups,
such amount shall be allocated between such Senior Certificate Groups pro rata
on the basis of the aggregate Class Certificate Balance of the Senior
Certificates (other than the related Class PO Certificates) in each such Senior
Certificate Group.
 
     The Senior Depletion Date for a Senior Certificate Group is the date on
which the Class Certificate Balances of all Classes of Senior Certificates of
such Senior Certificate Group have been reduced to zero.
 
     'Stated Principal Balance' means, as to any Mortgage Loan and Due Date, the
unpaid principal balance of such Mortgage Loan as of such Due Date, as specified
in the amortization schedule at the time relating thereto (before any adjustment
to such amortization schedule by reason of any moratorium or similar waiver or
grace period), after giving effect to any previous partial principal prepayments
and Liquidation Proceeds received and to the payment of principal due on such
Due Date and irrespective of any delinquency in payment by the related
Mortgagor. The Pool Principal Balance with respect to any Distribution Date
equals the aggregate of the Stated Principal Balances of the Mortgage Loans
outstanding on the Due Date in the month preceding the month of such
Distribution Date.
 
     The Senior Percentage of a Senior Certificate Group for any Distribution
Date is the lesser of (i) 100% and (ii) the percentage equivalent of a fraction
the numerator of which is the aggregate of the Class Certificate Balance or
Balances of the Class or Classes of Senior Certificates (other than the related
Class PO Certificates) of such Senior Certificate Group immediately prior to
such date and the denominator of which is the aggregate of the applicable Non-PO
Percentage of the Stated Principal Balance of each Mortgage Loan in the related
Loan Group as of the Due Date occurring in the month of such Distribution Date;
provided, however, that on any Distribution Date after two Senior Depletion
Dates have occurred, the Senior Percentage for the Senior Certificates of the
remaining Senior Certificate Group is the percentage equivalent of a fraction,
the numerator of which is the aggregate of the Class Certificate Balances of
each such Class of Senior Certificates (other than the Class PO Certificates)
immediately prior to such date and the denominator of which is the aggregate of
the
 
                                      S-33
 

<PAGE>
<PAGE>

Class Certificate Balances of all Classes of Certificates (other than the Class
PO Certificates), immediately prior to such date. For any Distribution Date on
and prior to the second Senior Depletion Date to occur, the Subordinated
Percentage for the portion of the Subordinated Certificates relating to a Loan
Group will be calculated as the difference between 100% and the Senior
Percentage of the Senior Certificate Group relating to such Loan Group on such
Distribution Date. After two Senior Depletion Dates have occurred the
Subordinated Percentage will represent the entire interest of the Subordinated
Certificates in the Mortgage Pool and will be calculated as the difference
between 100% and the Senior Percentage for such Distribution Date.
 
     The Senior Prepayment Percentage of a Senior Certificate Group for any
Distribution Date occurring during the five years beginning on the first
Distribution Date will equal 100%. Thereafter, such Senior Prepayment Percentage
will be, except as provided below, subject to gradual reduction as described in
the following paragraph. This disproportionate allocation of certain unscheduled
payments in respect of principal will have the effect of accelerating the
amortization of the Class or Classes of Senior Certificates of such Senior
Certificate Group (other than the related Class PO Certificates) while, in the
absence of Realized Losses, increasing the interest in the aggregate Stated
Principal Balance of the applicable Loan Group evidenced by the portion of
Subordinated Certificates related to such Loan Group. Increasing the respective
interest of such portion of the Subordinated Certificates relative to that of
the related Senior Certificates is intended to preserve the availability of the
subordination provided by such Subordinated Certificates.
 
     The Senior Prepayment Percentage of a Senior Certificate Group for any
Distribution Date occurring on or after the fifth anniversary of the first
Distribution Date will be as follows: (a) for any Distribution Date in the first
year thereafter, the related Senior Percentage plus 70% of the related
Subordinated Percentage for such Distribution Date; (b) for any distribution
date in the second year thereafter, the related Senior Percentage plus 60% of
the related Subordinated Percentage for such Distribution Date; (c) for any
Distribution Date in the third year thereafter, the related Senior Percentage
plus 40% of the related Subordinated Percentage for such Distribution date; (d)
for any Distribution Date in the fourth year thereafter, the related Senior
Percentage plus 20% of the related Subordinated Percentage for such Distribution
Date; (e) and for any Distribution Date thereafter, the related Senior
Percentage for such Distribution Date (unless on any of the foregoing
Distribution Dates the related Senior Percentage exceeds the initial Senior
Percentage for the Senior Certificates of such Senior Certificate Group, in
which case such Senior Prepayment Percentage for such Distribution Date will
once again equal 100%). Notwithstanding the foregoing, no decrease in the Senior
Prepayment Percentage of a Senior Certificate Group will occur if (i) as of the
first Distribution Date as to which any such decrease applies, more than an
average of 2% of the dollar amount of all monthly payments on the Mortgage Loans
in any Loan Group or, if such date is after the second Senior Depletion Date,
all the Mortgage Loans in the Mortgage Pool, due in each of the preceding twelve
months were delinquent 60 days or more (including for this purpose any such
Mortgage Loans in foreclosure and Mortgage Loans with respect to which the
related Mortgaged Property has been acquired by the Trust Fund) or (ii)
cumulative Realized Losses with respect to the Mortgage Loans in any Loan Group
or, if such date is after the second Senior Depletion Date, all the Mortgage
Loans in the Mortgage Pool, exceed (a) with respect to the Distribution Date on
the fifth anniversary of the first Distribution Date, 30% of (i) if such date is
on or prior to the second Senior Depletion Date, the Subordinated Percentage for
such Loan Group of the aggregate of the Stated Principal Balances of the
Mortgage Loans in such Loan Group, in each case as of the Cut-Off Date or (ii)
if such date is after the second Senior Depletion Date, the aggregate of the
Class Certificate Balances of the Subordinated Certificates as of the Cut-off
Date (in either case, the 'Original Subordinated Principal Balance'), (b) with
respect to the Distribution Date on the sixth anniversary of the first
Distribution Date, 35% of the applicable Original Subordinated Principal
Balance, (c) with respect to the Distribution Date on the seventh anniversary of
the first Distribution Date, 40% of the applicable Original Subordinated
Principal Balance, (d) with respect to the Distribution Date on the eighth
anniversary of the first Distribution Date, 45% of the applicable Original
Subordinated Principal Balance, and (e) with respect to the Distribution Date on
the ninth anniversary of the First Distribution Date, 50% of the applicable
Original Subordinated Principal Balance. The Subordinated Prepayment Percentage
of the related Loan Group for any Distribution Date will be calculated as the
difference between 100% and the related Senior Prepayment Percentage for such
date.
 
     If on any Distribution Date the allocation to any Class of Senior
Certificates of a Senior Certificate Group (other than the Class PO
Certificates) then entitled to distributions of full and partial principal
prepayments and other amounts in the percentage required above would reduce the

such amounts for such Distribution Date will be limited to the percentage
necessary to reduce the related Class Certificate Balance to zero.
 
     Subordinated Principal Distribution Amount.  On each Distribution Date, to
the extent of Available Funds therefor, an amount equal to the Subordinated
Principal Distribution Amount for such Distribution Date will be distributed as
principal of the Classes of Subordinated Certificates. Except as provided in the
next paragraph, each Class of Subordinated Certificates will be entitled to
receive its pro rata share of the Subordinated Principal Distribution Amount
(based on its respective Class Certificate Balance), in each case to the extent
of the amount available from Available Funds for all Loan Groups for
distribution of principal on such Class. Distributions of principal of the
Subordinated Certificates will be made on each Distribution Date sequentially to
the Classes of Subordinated Certificates in the order of their numerical Class
designations, beginning with the Class B-1 Certificates, until each such Class
has received its respective pro rata share for such Distribution Date.
 
     With respect to each Class of Subordinated Certificates, if on any
Distribution Date the sum of the related Class Subordination Percentages of such
Class and all Classes of Subordinated Certificates which have higher numerical
Class designations than such Class, (the 'Applicable Credit Support Percentage')
is less than the Applicable Credit Support Percentage for such Class on the date
of issuance of the Certificates (the 'Original Applicable Credit Support
Percentage'), no distribution of partial principal prepayments and principal
prepayments in full will be made to any such Classes (the 'Restricted Classes')
and the amount otherwise distributable to the Restricted Classes in respect of
such partial principal prepayments and principal prepayments in full will be
allocated among the remaining Classes of Subordinated Certificates, pro rata,
based upon their respective Class Certificate Balances, and distributed in the
order described above.
 
     The Class Subordination Percentage with respect to any Distribution Date
and each Class of Subordinated Certificates will equal the fraction (expressed
as a percentage) the numerator of which is the Class Certificate Balance of such
Class of Subordinated Certificates, immediately prior to such Distribution Date
and the denominator of which is the aggregate of the Class Certificate Balances
of all Classes of Certificates immediately prior to such Distribution Date.
 
     The approximate Original Applicable Credit Support Percentages for the
Subordinated Certificates on the date of issuance of the Certificates are
expected to be as follows:

     The Subordinated Principal Distribution Amount for any Distribution Date on
and prior to a Senior Depletion Date will equal the aggregate of the amount
calculated for each Loan Group as follows: (A) the sum of (i) the Subordinated
Percentage for such Loan Group of the applicable Non-PO Percentage of all
amounts described in clauses (a) through (d) of the definition of 'Non-PO
Formula Principal Amount', with respect to such Loan Group, for such
Distribution Date, (ii) with respect to each Mortgage Loan in such Loan Group
that became a Liquidated Mortgage Loan during the calendar month preceding the
month of such Distribution Date, the applicable Non-PO Percentage of Liquidation
Proceeds allocable to principal received with respect to such Mortgage Loan,
after application of such amounts pursuant to clause (ii) of the definition of
Senior Principal Distribution Amount for the related Senior Certificate Group
and (iii) the Subordinated Prepayment Percentage for such Loan Group of the
applicable Non-PO Percentage of amounts described in clause (f) of the
definition of 'Non-PO Formula Principal Amount', with respect to such Loan
Group, for such Distribution Date; reduced by (B) the amount of any payments in
respect of related Class PO Deferred Amounts relating to the applicable Class PO
Certificates on such Distribution Date from Available Funds for such Loan Group.
Any such payment in respect of Class PO Deferred Amounts will be deducted first
from the amounts described in clauses (i) and (ii) above and then from the
amounts described in clause (iii) above. Notwithstanding the foregoing, on any
Distribution Date after a Senior Depletion Date the Non-PO Formula Principal
Amount for the related Loan Group will be distributed as part of the Senior
Principal Distribution Amounts for the remaining Senior Certificate Groups;
provided, that if a second Senior Depletion Date occurs, the Subordinated
Principal Distribution Amount will not be calculated by Loan Group but will
equal the amount calculated pursuant to the formula set forth above based on the
applicable Subordinated Percentage for the Subordinated Certificates for
 
                                      S-35

such Distribution Date, of all of the Mortgage Loans in the Mortgage Pool, as
opposed to the Mortgage Loans in the related Loan Group.
 
     Residual Certificates.  The Class A-R Certificates will remain outstanding
for so long as the Trust Fund shall exist, whether or not they are receiving
current distributions of principal or interest. In addition to distributions of
interest and principal as described above, on each Distribution Date the holders
of the Class A-R Certificates will be entitled to receive any Available Funds
for all Loan Groups remaining after payment of interest and principal on the
Senior Certificates, Class PO Deferred Amounts on the Class PO Certificates and
interest and principal on the Subordinated Certificates for such Distribution
Date, as described above. It is not anticipated that there will be any
significant amounts remaining for any such distribution.
 
     Class PO Principal Distribution Amount. On each Distribution Date,
distributions of principal of each Class of Class PO Certificates will be made
in an amount (each a 'Class PO Principal Distribution Amount') equal to the
lesser of (x) the PO Formula Principal Amount for the related Loan Group for
such Distribution Date and (y) the product of (i) the sum of (a) Available Funds
for the related Loan Group remaining after distribution of interest on the
related Classes of Senior Certificates and (b) Available Funds for the other
Loan Groups remaining after distributions of interest and principal on the
Senior Certificates of the related Senior Certificate Groups and (ii) a
fraction, the numerator of which is such PO Formula Principal Amount and the
denominator of which is the sum of such PO Formula Principal Amount and the
related Senior Principal Distribution Amount.
 
     If a Class PO Principal Distribution Amount for a Loan Group on a
Distribution Date is calculated as provided in clause (y) above, principal
distributions to holders of the Class or Classes of Senior Certificates (other
than such Class PO Certificates) of the related Senior Certificate Group will be
in amount equal to the product of (i) the sum of (a) Available Funds for the
related Loan Group remaining after distribution of interest on such Senior
Certificates and (b) Available Funds for the other Loan Groups remaining after
distributions of interest and principal on the Senior Certificates of the
related Senior Certificate Groups and (ii) a fraction, the numerator of which is
the related Senior Principal Distribution Amount and the denominator of which is
the sum of such Senior Principal Distribution Amount and the PO Formula
Principal Amount for the related Loan Group.
 
     The PO Formula Principal Amount for any Distribution Date and Class of
Class PO Certificates will equal the sum of the applicable PO Percentage of (a)
all monthly payments of principal due on each Mortgage Loan in the related Loan
Group on the related Due Date, (b) the principal portion of the purchase price
of each Mortgage Loan in the related Loan Group that was repurchased by the
Seller or another person pursuant to the Agreement as of such Distribution Date,
(c) the Substitution Adjustment Amount in connection with any Deleted Mortgage
Loan in the related Loan Group received with respect to such Distribution Date,
(d) any Insurance Proceeds or Liquidation Proceeds allocable to recoveries of
principal of Mortgage Loans in the related Loan Group that are not yet
Liquidated Mortgage Loans received during the calendar month preceding the month
of such Distribution Date, (e) with respect to each Mortgage Loan in the related
Loan Group that became a Liquidated Mortgage Loan during the calendar month
preceding the month of such Distribution Date, the amount of Liquidation
Proceeds allocable to principal received with respect to such Mortgage Loan, and
(f) all partial and full principal prepayments by borrowers on the Mortgage
Loans in the related Loan Group received during the calendar month preceding the
month of such Distribution Date; provided, however, that if a Bankruptcy Loss
that is an Excess Loss is sustained with respect to a Discount Mortgage Loan
that is not a Liquidated Mortgage Loan, the PO Formula Principal Amount will be
reduced on the related Distribution Date by the applicable PO Percentage of the
principal portion of such Bankruptcy Loss.
 
ALLOCATION OF LOSSES
 
     On each Distribution Date, the applicable PO Percentage of any Realized
Loss, including any Excess Loss, on a Discount Mortgage Loan in a Loan Group
will be allocated to the related Class of Class PO Certificates until the Class
Certificate Balance thereof is reduced to zero. The amount of any such Realized
Loss, other than an Excess Loss, allocated on or prior to the Senior Credit
Support Depletion Date will be treated as a Class PO Deferred Amount. To the
extent funds are available on such Distribution Date or on any future
Distribution Date from amounts that would otherwise be allocable from Available
Funds of all Loan Groups to the Subordinated Principal Distribution Amount,
Class PO Deferred Amounts will be paid on the Class PO Certificates prior to
distributions of principal on the Subordinated Certificates. Any distribution of
Available Funds for a Loan Group
 
                                      S-36
 

<PAGE>
<PAGE>

in respect of unpaid Class PO Deferred Amounts will not further reduce the Class
Certificate Balance of the applicable Class of Class PO Certificates. The Class
PO Deferred Amounts will not bear interest. The Class Certificate Balance of the
Class of Subordinated Certificates then outstanding with the highest numerical
Class designation will be reduced by the amount of any payments in respect of
Class PO Deferred Amounts. After the Senior Credit Support Depletion Date, no
new Class PO Deferred Amounts will be created. On each Distribution Date, the
applicable Non-PO Percentage of any Realized Loss, other than any Excess Loss,
will be allocated first to the Subordinated Certificates, in the reverse order
of their numerical Class designations (beginning with the Class of Subordinated
Certificates then outstanding with the highest numerical Class designation), in
each case until the Class Certificate Balance of the respective Class of
Certificates has been reduced to zero, and then to the Senior Certificates of
the related Senior Certificate Group (other than the related Class PO
Certificates), pro rata, based upon their respective Class Certificate Balances.
 
     On each Distribution Date, the applicable Non-PO Percentage of Excess
Losses on the Mortgage Loans in a Loan Group will be allocated pro rata among
the Classes of Senior Certificates in the related Senior Certificate Group
(other than the Class PO and Notional Amount Certificates) and the Subordinated
Certificates based upon, with respect to the Senior Certificates, their
respective Class Certificate Balances and, with respect to the Subordinated
Certificates, their pro rata share (based on their respective Class Certificate
Balances) of the Subordinated Percentage relating to such Loan Group of the
aggregate of the applicable Non-PO Percentage of the Stated Principal Balance of
each Mortgage Loan in such Loan Group as of the Due Date occurring in the month
of such Distribution Date; provided, however, on any Distribution Date after a
Senior Depletion Date for a Senior Certificate Group, such Excess Losses on the
Mortgage Loans in the related Loan Group will be allocated to the Subordinated
Certificates based upon their respective Class Certificate Balances; and
provided, further, that after the Senior Credit Support Depletion Date, if a
Loan Group is overcollateralized (i.e., the aggregate of the Non-PO Percentages
of the Stated Principal Balances of the Mortgage Loans in such Loan Group
exceeds the aggregate Class Certificate Balance of the related Senior
Certificates, other than the related Class PO Certificates), the Non-PO
Percentage of any Realized Loss in such Loan Group will not be allocated to such
Senior Certificates until such overcollateralization is reduced to zero or
becomes negative.
 
     Because principal distributions are paid to certain Classes of Senior
Certificates of a Senior Certificate Group (other than the related Class PO
Certificates) before other Classes of such Senior Certificate Group, holders of
such Senior Certificates that are entitled to receive principal later bear a
greater risk of being allocated Realized Losses on the Mortgage Loans in the
related Loan Group than holders of Classes that are entitled to receive
principal earlier.
 
     In general, a 'Realized Loss' means, with respect to a Liquidated Mortgage
Loan, the amount by which the remaining unpaid principal balance of the Mortgage
Loan exceeds the amount of Liquidation Proceeds applied to the principal balance
of the related Mortgage Loan. 'Excess Losses' are (i) Special Hazard Losses in
excess of the Special Hazard Loss Coverage Amount, (ii) Bankruptcy Losses in
excess of the Bankruptcy Loss Coverage Amount and (iii) Fraud Losses in excess
of the Fraud Loss Coverage Amount. 'Bankruptcy Losses' are losses that are
incurred as a result of Debt Service Reductions and Deficient Valuations.
'Special Hazard Losses' are Realized Losses in respect of Special Hazard
Mortgage Loans. 'Fraud Losses' are Realized Losses sustained by reason of a
default arising from fraud, dishonesty or misrepresentation. See 'Credit
Enhancement -- Subordination of Certain Classes' herein.
 
     A 'Liquidated Mortgage Loan' is a defaulted Mortgage Loan as to which the
Master Servicer has determined that all recoverable liquidation and insurance
proceeds have been received. A 'Special Hazard Mortgage Loan' is a Liquidated
Mortgage Loan as to which the ability to recover the full amount due thereunder
was substantially impaired by a hazard not insured against under a standard
hazard insurance policy of the type described in the Prospectus under 'Credit
Enhancement -- Special Hazard Insurance Policies.' See 'Credit
Enhancement -- Subordination of Certain Classes' herein.
 
STRUCTURING ASSUMPTIONS
 
     Unless otherwise specified, the information in the tables in this
Prospectus Supplement has been prepared on the basis of the following assumed
characteristics of the Mortgage Loans and the following additional assumptions
(collectively, the 'Structuring Assumptions'): (i) Each Loan Group consists of
two Mortgage Loans with the following characteristics:

(ii) the Mortgage Loans prepay at the specified constant Prepayment Assumption,
(iii) no defaults in the payment by the Mortgagor of principal of and interest
on the Mortgage Loans are experienced, (iv) scheduled payments on the Mortgage
Loans are received on the first day of each month commencing in the calendar
month following the Closing Date and are computed prior to giving effect to
prepayments received on the last day of the prior month, (v) prepayments are
allocated as described herein without giving effect to loss and delinquency
tests, (vi) there are no Net Interest Shortfalls and prepayments represent
prepayments in full of the Mortgage Loans and are received on the last day of
each month, commencing in the calendar month of the Closing Date, (vii) the
scheduled monthly payment for the Mortgage Loans has been calculated based on
the assumed mortgage loan characteristics described in item (i) above such that
the Mortgage Loans will amortize in amounts sufficient to repay the principal
balance of each such assumed mortgage loan by its amortizing remaining term,
(viii) the initial Class Certificate Balance or Notional Amount, as applicable,
of each Class of Certificates is as set forth on the cover page hereof and under
'Summary of Terms -- Certificates other than the Offered Certificates' and the
initial Component Balances of the Components comprising the Component
Certificates are as set forth under ' -- Principal -- Components' herein, (ix)
interest accrues on each Class of Certificates at the applicable interest rate
set forth or described on the cover hereof or described herein, (x)
distributions in respect of the Certificates are received in cash on the 25th
day of each month commencing in the calendar month following the Closing Date,
(xi) the closing date of the sale of the Offered Certificates is July 30, 1998,
(xii) the Seller is not required to repurchase or substitute for any Mortgage
Loan, (xiii) the Master Servicer does not exercise any option to repurchase the
Mortgage Loan described herein under ' -- Optional Purchase of Defaulted Loans'
and ' -- Optional Termination,' (xiv) no Class of Subordinated Certificates
becomes a Restricted Class and (xv) no Available Funds from a Loan Group are
used to make distributions on Senior Certificates related to another Loan Group.
While it is assumed that the Mortgage Loans prepay at the specified constant
Prepayment Assumption, this is not likely to be the case. Moreover,
discrepancies will exist between the characteristics of the actual Mortgage
Loans which will be delivered to the Trustee and characteristics of the Mortgage
Loans assumed in preparing the tables herein.
 
     Prepayments of mortgage loans commonly are measured relative to a
prepayment standard or model. The prepayment model used in this Prospectus
Supplement (the 'Prepayment Assumption') represents an assumed rate of
prepayment each month relative to the then outstanding principal balance of a
pool of mortgage loans. A 100% Prepayment Assumption assumes a Constant
Prepayment Rate ('CPR') of 4.0% per annum of the then outstanding principal
balance of such mortgage loans in the first month of the life of the mortgage
loans and an additional 1.09090909% (precisely 12/11) per annum in each month
thereafter until the eleventh month. Beginning in the twelfth month and in each
month thereafter during the life of the mortgage loans, a 100% Prepayment
Assumption assumes a CPR of 16% per annum each month. As used in the table
below, a 50% Prepayment Assumption assumes prepayment rates equal to 50% of the
Prepayment Assumption. Correspondingly, a 200% Prepayment Assumption assumes
prepayment rates equal to 200% 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.
 
OPTIONAL PURCHASE OF DEFAULTED LOANS
 
     The Master Servicer may, at its option, purchase from the Trust Fund any
Mortgage Loan which is delinquent in payment by 91 days or more. Any such
purchase shall be at a price equal to 100% of the Stated Principal Balance of
such Mortgage Loan plus accrued interest thereon at the applicable Mortgage Rate
from the
 
                                      S-38

<PAGE>

date through which interest was last paid by the related Mortgagor or advanced
to the first day of the month in which such amount is to be distributed.
 
OPTIONAL TERMINATION
 
     The Master Servicer will have the right to repurchase all remaining
Mortgage Loans and REO Properties in the Mortgage Pool and thereby effect early
retirement of the Certificates, subject to the Pool Principal Balance of such
Mortgage Loans and REO Properties at the time of repurchase being less than 10%
of the Cut-off Date Pool Principal Balance. In the event the Master Servicer
exercises such option, the purchase price distributed with respect to each
Certificate will be 100% of its then outstanding principal balance plus any
Class PO Deferred Amounts plus any unpaid accrued interest on such principal
balance or Notional Amount, as applicable, at the applicable Pass-Through Rate
(in each case subject to reduction as provided in the Agreement if the purchase
price is based in part on the appraised value of any REO Properties and such
appraised value is less than the Stated Principal Balance of the related
Mortgage Loans). Distributions on the Certificates in respect of any such
optional termination will first be paid to the Senior Certificates and then,
except as set forth in the Agreement, to the Subordinated Certificates. The
proceeds from any such distribution may not be sufficient to distribute the full
amount to which each Class of Certificates is entitled if the purchase price is
based in part on the appraised value of any REO Property and such appraised
value is less than the Stated Principal Balance of the related Mortgage Loan.
 
THE TRUSTEE
 
     The Bank of New York will be the Trustee under the Agreement. The Depositor
and the Master Servicer may maintain other banking relationships in the ordinary
course of business with The Bank of New York. Offered Certificates may be
surrendered at the Corporate Trust Office of the Trustee located at 101 Barclay
Street, 12E, New York, New York 10286, Attention: Corporate Trust Administration
or at such other addresses as the Trustee may designate from time to time.
 
RESTRICTIONS ON TRANSFER OF THE CLASS A-R CERTIFICATES
 
     The Class A-R Certificates will be subject to the restrictions on transfer
described in the Prospectus under 'Federal Income Tax Consequences -- Taxation
of Holders of Residual Interest Securities -- Restrictions on Ownership and
Transfer of Residual Interest Securities' and ' -- Tax Treatment of Foreign
Investors.' The Agreement provides that the Class A-R Certificates (in addition
to certain other Classes of Certificates) may not be acquired by an ERISA Plan.
See 'ERISA Considerations' herein. Each Class A-R Certificate will contain a
legend describing the foregoing restrictions.
 
                 YIELD, PREPAYMENT AND MATURITY CONSIDERATIONS
 
GENERAL
 
     The effective yields to the holders of the Delay Certificates will be lower
than the yields otherwise produced by the applicable rate at which interest is
passed through to such holders and the purchase price of such Certificates
because monthly distributions will not be payable to such holders until the 25th
day (or, if such day is not a business day, the following business day) of the
month following the month in which interest accrues on the Mortgage Loans
(without any additional distribution of interest or earnings thereon in respect
of such delay).
 
     Delinquencies on the Mortgage Loans which are not advanced by or on behalf
of the Master Servicer (because amounts, if advanced, would be nonrecoverable),
will adversely affect the yield on the Certificates. Because of the priority of
distributions, shortfalls resulting from delinquencies not so advanced will be
borne first by the Subordinated Certificates (in the reverse order of their
numerical Class designations), and then by the Senior Certificates of the Senior
Certificate Group to which such shortfall relates. If, as a result of such
shortfalls, the aggregate of the Class Certificate Balances of all Classes of
Certificates exceeds the Pool Principal Balance, the Class Certificate Balance
of the Class of Subordinated Certificates then outstanding with the highest
numerical Class designation will be reduced by the amount of such excess.
 
                                      S-39
 

<PAGE>
<PAGE>

     Net Interest Shortfalls will adversely affect the yields on the Senior
Certificates of the Senior Certificate Group to which they relate and the
Subordinated Certificates. In addition, although all losses initially will be
borne by the Subordinated Certificates (either directly or indirectly through
distributions in respect of Class PO Deferred Amounts), in the reverse order of
their numerical Class designations, Excess Losses on the Mortgage Loans in a
Loan Group will be borne by all Classes of Senior Certificates in the related
Senior Certificate Group and the Subordinated Certificates in the manner set
forth herein under 'Description of the Certificates -- Allocation of Losses.'
Moreover, since the Subordinated Principal Distribution Amount for each
Distribution Date will be reduced by the amount of any distributions on such
Distribution Date in respect of Class PO Deferred Amounts, the amount
distributable as principal on each such Distribution Date to each Class of
Subordinated Certificates will be less than it otherwise would be in the absence
of such Class PO Deferred Amounts. As a result, the yields on the Offered
Certificates will depend on the rate and timing of Realized Losses, including
Excess Losses. Excess Losses could occur at a time when one or more Classes of
Subordinated Certificates are still outstanding and otherwise available to
absorb other types of Realized Losses.
 
PREPAYMENT CONSIDERATIONS AND RISKS
 
     The rate of principal payments on the Offered Certificates, the aggregate
amount of distributions on the Offered Certificates and the yields to maturity
of the Offered Certificates will be related to the rate and timing of payments
of principal on the Mortgage Loans in the related Loan Group, with respect to
the Senior Certificates, and all of the Mortgage Loans, with respect to the
Subordinated Certificates. The rate of principal payments on the Mortgage Loans
will in turn be affected by the amortization schedules of the Mortgage Loans and
by the rate of principal prepayments (including for this purpose prepayments
resulting from refinancing, liquidations of the Mortgage Loans due to defaults,
casualties, condemnations and repurchases by the Seller or Master Servicer). The
Mortgage Loans may be prepaid by the Mortgagors at any time without a prepayment
penalty. The Mortgage Loans are subject to the 'due-on-sale' provisions included
therein. However, the Master Servicer may choose not to accelerate a Mortgage
Loan upon the conveyance of the related Mortgaged Property if the Master
Servicer would make a similar decision with respect to a comparable mortgage
loan held for its own account. See 'The Mortgage Pool' herein.
 
     Prepayments, liquidations and purchases of the Mortgage Loans in a Loan
Group (including any optional purchase by the Master Servicer of a defaulted
Mortgage Loan in such Loan Group and any optional repurchase of the remaining
Mortgage Loans in connection with the termination of the Trust Fund, in each
case as described herein) will result in distributions on the Senior
Certificates of the related Senior Certificate Group and the Subordinated
Certificates of principal amounts which would otherwise be distributed over the
remaining terms of the Mortgage Loans. Since the rate of payment of principal on
the Mortgage Loans will depend on future events and a variety of other factors,
no assurance can be given as to such rate or the rate of principal prepayments.
The extent to which the yield to maturity of a Class of Offered Certificates may
vary from the anticipated yield will depend upon the degree to which such
Offered Certificate is purchased at a discount or premium, and the degree to
which the timing of payments thereon is sensitive to prepayments, liquidations
and purchases of the Mortgage Loans in the related Loan Group, with respect to
the Senior Certificates, and all of the Mortgage Loans, with respect to the
Subordinated Certificates. Further, an investor should consider the risk that,
in the case of the Class PO Certificates and any other Offered Certificate
purchased at a discount, a slower than anticipated rate of principal payments
(including prepayments) on the Mortgage Loans in the related Loan Group, with
respect to the Senior Certificates, and all of the Mortgage Loans, with respect
to the Subordinated Certificates could result in an actual yield to such
investor that is lower than the anticipated yield and, in the case of the
Notional Amount Certificates and any other Offered Certificate purchased at a
premium, a faster than anticipated rate of principal payments on the Mortgage
Loans in the related Loan Group, with respect to the Senior Certificates, and
all of the Mortgage Loans, with respect to the Subordinated Certificates, could
result in an actual yield to such investor that is lower than the anticipated
yield. Investors in the Notional Amount Certificates should carefully consider
the risk that a rapid rate of principal prepayments on the Mortgage Loans could
result in the failure of such investors to recover their initial investments.
 
     The rate of principal payments (including prepayments) on pools of mortgage
loans may vary significantly over time and may be influenced by a variety of
economic, geographic, social and other factors, including changes in mortgagors'
housing needs, job transfers, unemployment, mortgagors' net equity in the
mortgaged properties and servicing decisions (including the decision whether or
not to exercise its rights under any due-on-
 
                                      S-40

sale clause). In general, if prevailing interest rates were to fall
significantly below the Mortgage Rates on the Mortgage Loans, the Mortgage Loans
could be subject to higher prepayment rates than if prevailing interest rates
were to remain at or above the Mortgage Rates on the Mortgage Loans. Conversely,
if prevailing interest rates were to rise significantly, the rate of prepayments
on the Mortgage Loans would generally be expected to decrease. No assurances can
be given as to the rate of prepayments on the Mortgage Loans in stable or
changing interest rate environments.
 
     As described herein under 'Description of the Certificates -- Principal,'
the applicable Senior Prepayment Percentage of the applicable Non-PO Percentage
of all principal prepayments will be initially distributed to the Classes of
Senior Certificates (other than the Class I-A-10, Class I-A-11, Class I-A-12,
Class II-A-1, Class II-A-5 and Class PO Certificates) of the related Senior
Certificate Group then entitled to receive principal distributions. This may
result in all (or a disproportionate percentage) of such principal payments
being distributed to holders of certain Classes of Senior Certificates (other
than the Class I-A-10, Class I-A-11, Class I-A-12, Class II-A-1, Class II-A-5
and Class PO Certificates) and none (or less than their pro rata share) of such
principal prepayments being distributed to holders of the Class I-A-10, Class
I-A-11, Class I-A-12, Class II-A-1, Class II-A-5 and Subordinated Certificates
during the periods of time described in the definitions of 'Senior Prepayment
Percentage.' Holders of the Class I-A-10, Class I-A-11, Class I-A-12, Class
II-A-1, Class II-A-5 Certificates will generally only receive principal payments
after five years.
 
     The yields to maturity on the Senior Certificates in a Senior Certificate
Group also may be affected by the rate of principal payments on the Mortgage
Loans in the other Loan Groups to the extent that a Senior Depletion Date occurs
for one of the other Senior Certificates Groups. In such event, the Non-PO
Formula Principal Amount of the Loan Group for which the Senior Depletion Date
occurred will be included as part of the Senior Principal Distribution Amounts
for the remaining Senior Certificate Groups. As a result, the Senior
Certificates (other than the related Class PO Certificates) will amortize faster
than they otherwise would have in the absence of such Senior Depletion Date.
 
     The timing of changes in the rate of prepayments on the Mortgage Loans may
significantly affect an investor's actual yield to maturity, even if the average
rate of principal payments is consistent with an investor's expectation. In
general, the earlier a prepayment of principal on the Mortgage Loans, the
greater the effect on an investor's yield to maturity. The effect on an
investor's yield as a result of principal payments occurring at a rate higher
(or lower) than the rate anticipated by the investor during the period
immediately following the issuance of the Offered Certificates may not be offset
by a subsequent like decrease (or increase) in the rate of principal payments.
 
     The tables below indicate the sensitivity of the pre-tax corporate bond
equivalent yields to maturity of certain Classes of Certificates to various
constant Prepayment Assumptions and in the case of the Class I-A-9 Certificates
at various constant levels of LIBOR. The yields set forth in the tables were
calculated by determining the monthly discount rates that, when applied to the
assumed stream of cash flows to be paid on the applicable Class of Certificates,
would cause the discounted present value of such assumed stream of cash flows to
equal the assumed purchase price of such Classes and converting such monthly
rates to corporate bond equivalent rates. Such calculations do not take into
account variations that may occur in the interest rates at which investors may
be able to reinvest funds received by them as distributions on certain Classes
of Certificates and consequently do not purport to reflect the return on any
investment in any such Class of Certificates when such reinvestment rates are
considered.
 
SENSITIVITY OF THE INVERSE FLOATING RATE CERTIFICATES
 
     THE YIELD TO INVESTORS IN THE CLASS I-A-9 CERTIFICATES WILL BE VERY
SENSITIVE TO THE LEVEL OF LIBOR AND THE RATE AND TIMING OF PRINCIPAL PAYMENTS
(INCLUDING PREPAYMENTS) OF THE MORTGAGE LOANS IN LOAN GROUP 1, WHICH GENERALLY
CAN BE PREPAID AT ANY TIME. AS INDICATED IN THE TABLE BELOW, AN INCREASING LEVEL
OF PREPAYMENTS AND/OR LIBOR WILL HAVE A NEGATIVE EFFECT ON THE YIELD TO
INVESTORS IN THE INVERSE FLOATING RATE CERTIFICATES.
 
     Changes in the level of LIBOR may not correlate with changes in prevailing
mortgage interest rates. It is possible that lower prevailing mortgage interest
rates, which might be expected to result in faster prepayments, could occur
concurrently with an increased level of LIBOR.
 
     The information set forth in the following table was prepared on the basis
of the Structuring Assumptions and the assumptions that (i) the interest rate
applicable to the Inverse Floating Rate Certificates for each Interest

     It is highly unlikely that all of the Mortgage Loans in Loan Group 1 will
have the characteristics assumed or that the Mortgage Loans in Loan Group 1 will
prepay at the same rate until maturity or that all of the Mortgage Loans in Loan
Group 1 will prepay at the same rate or time. In addition, there can be no
assurance that LIBOR will correspond to the levels shown herein and it is highly
unlikely that the level of LIBOR will remain constant. As a result of these
factors, the pre-tax yield on the Inverse Floating Rate Certificates is likely
to differ from those shown in the table above, even if all of the Mortgage Loans
in Loan Group 1 prepay at the indicated percentages of the Prepayment Assumption
and LIBOR is at the indicated level. No representation is made as to the actual
rate of principal payments on the Mortgage Loans in Loan Group 1 or the level of
LIBOR for any period or over the lives of the Inverse Floating Rate Certificates
or as to the yield on the Inverse Floating Rate Certificates. Investors must
make their own decisions as to the appropriate combinations of prepayment
assumptions and assumptions regarding the level of LIBOR to be used in deciding
whether to purchase the Inverse Floating Rate Certificates.
 
SENSITIVITY OF THE CLASS PO CERTIFICATES
 
     THE CLASS PO CERTIFICATES WILL BE 'PRINCIPAL ONLY' CERTIFICATES AND WILL
NOT BEAR INTEREST. AS INDICATED IN THE TABLE BELOW, A LOW RATE OF PRINCIPAL
PAYMENTS (INCLUDING PREPAYMENTS) OF THE DISCOUNT MORTGAGE LOANS IN THE RELATED
LOAN GROUP WILL HAVE A NEGATIVE EFFECT ON THE YIELD TO INVESTORS IN THE CLASS PO
CERTIFICATES.
 
     As described above under 'Description of the Certificates -- Principal,'
each Class PO Principal Distribution Amount is calculated by reference to the
principal payments (including prepayments) on the Discount Mortgage Loans in the
related Loan Group. The Discount Mortgage Loans will have lower Adjusted Net
Mortgage Rates (and lower Mortgage Rates) than the other Mortgage Loans. In
general, mortgage loans with higher mortgage rates tend to prepay at higher
rates than mortgage loans with relatively lower mortgage rates in response to a
given reduction in market interest rates. As a result, the Discount Mortgage
Loans in a Loan Group may prepay at lower rates, thereby reducing the rate of
payment of principal and the resulting yield of the related Class PO
Certificates.
 
     The tables below indicate the sensitivity of the pre-tax corporate bond
equivalent yields to maturity of the Class PO Certificates to various constant
percentages of the Prepayment Assumption. The yields set forth in the table were
calculated by determining the monthly discount rates that, when applied to the
assumed stream of cash flows to be paid on the Class PO Certificates, would
cause the discounted present value of each such assumed stream of cash flows to
equal the assumed purchase price of each such Class and converting such monthly
rates to corporate bond equivalent rates. Such calculations do not take into
account variations that may occur in the interest rates at which investors may
be able to reinvest funds received by them as distributions on the Class PO
Certificates and consequently do not purport to reflect the return on any
investment in each such Class of Certificates when such reinvestment rates are
considered.

     It is highly unlikely that all of the Mortgage Loans will have the
characteristics assumed or that the Discount Mortgage Loans in a Loan Group will
prepay at the same rate until maturity or that all of the Discount Mortgage
Loans in a Loan Group will prepay at the same rate or time. As a result of these
factors, the pre-tax yield on any Class of Class PO Certificates is likely to
differ from those shown in the table above, even if all of the related Discount
Mortgage Loans prepay at the indicated percentages of the Prepayment Assumption.
No representation is made as to the actual rate of principal payments on the
Discount Mortgage Loans for any period or over the lives of any Class of Class
PO Certificates or as to the yield on any Class of Class PO Certificates.
Investors must make their own decisions as to the appropriate prepayment
assumptions to be used in deciding whether to purchase the Class PO
Certificates.
 
SENSITIVITY OF THE NOTIONAL AMOUNT CERTIFICATES
 
     AS INDICATED IN THE TABLE BELOW, THE YIELDS TO INVESTORS ON THE NOTIONAL
AMOUNT CERTIFICATES WILL BE SENSITIVE TO THE RATE OF PRINCIPAL PAYMENTS
(INCLUDING PREPAYMENTS) OF THE NON-DISCOUNT MORTGAGE LOANS IN THE RELATED LOAN
GROUP, PARTICULARLY THOSE WITH HIGH ADJUSTED NET MORTGAGE RATES. THE MORTGAGE
LOANS GENERALLY CAN BE PREPAID AT ANY TIME. ON THE BASIS OF THE ASSUMPTIONS
DESCRIBED BELOW, THE YIELD TO MATURITY ON THE CLASS X-1, CLASS X-2 AND CLASS X-3
CERTIFICATES WOULD BE APPROXIMATELY 0% IF PREPAYMENTS ON THE RELATED MORTGAGE
LOANS WERE TO OCCUR AT A CONSTANT RATE OF APPROXIMATELY 179%, 180% AND 180%,
RESPECTIVELY, OF THE PREPAYMENT ASSUMPTION. IF THE ACTUAL PREPAYMENT RATE OF THE
NON-DISCOUNT MORTGAGE LOANS IN LOAN GROUP 1, IN LOAN GROUP 2 AND LOAN GROUP 3,
AS APPLICABLE, WERE TO EXCEED THE APPLICABLE LEVEL FOR AS LITTLE AS ONE MONTH
WHILE EQUALING SUCH LEVEL FOR THE REMAINING MONTHS, THE INVESTORS IN THE
NOTIONAL AMOUNT CERTIFICATES WOULD NOT FULLY RECOUP THEIR INITIAL INVESTMENTS.
 
     As described above under 'Description of the Certificates -- General,' the
Pass-Through Rate of each Class of Notional Amount Certificates in effect from
time to time is calculated by reference to the Adjusted Net Mortgage Rates of
the Non-Discount Mortgage Loans in Loan Group 1, in Loan Group 2 and in Loan
Group 3, as applicable. In general, mortgage loans with higher mortgage rates
tend to prepay at higher rates than mortgage loans with relatively lower
mortgage rates in response to a given change in market interest rates. As a
result, the applicable Mortgage Loans may prepay at higher rates, thereby
reducing the Pass-Through Rate and Notional Amount of the Notional Amount
Certificates of the related Senior Certificate Group.
 
     The information set forth in the following table has been prepared on the
basis of the Structuring Assumptions (which assume no Realized Losses), and on
the assumption that the purchase prices (expressed as a percentage of initial
Notional Amount) of the Class X-1, Class X-2 and Class X-3 Certificates are as
follows:

     It is highly unlikely that all of the Mortgage Loans will have the
characteristics assumed or that the Non-Discount Mortgage Loans in a Loan Group
will prepay at any constant rate until maturity or that all of the Non-Discount
Mortgage Loans in a Loan Group will prepay at the same rate or time. As a result
of these factors, the pre-tax yields on any Class of Notional Amount
Certificates are likely to differ from those shown in the table above, even if
all of the related Mortgage Loans prepay at the indicated percentages of the

ADDITIONAL INFORMATION
 
     The Depositor intends to file certain additional yield tables and other
computational materials with respect to one or more Classes of Offered
Certificates with the Commission in a report on Form 8-K. Such tables and
materials were prepared by one or more of the Underwriters at the request of
certain prospective investors, based on assumptions provided by, and satisfying
the special requirements of, such prospective investors. Such tables and
assumptions may be based on assumptions that differ from the Structuring
Assumptions. Accordingly, such tables and other materials may not be relevant to
or appropriate for investors other than those specifically requesting them.
 
WEIGHTED AVERAGE LIVES OF THE OFFERED CERTIFICATES
 
     The weighted average life of an Offered Certificate is determined by (a)
multiplying the amount of the reduction, if any, of the Class Certificate
Balance of such Certificate on each Distribution Date by the number of years
from the date of issuance to such Distribution Date, (b) summing the results and
(c) dividing the sum by the aggregate amount of the reductions in Class
Certificate Balance of such Certificate referred to in clause (a).
 
     For a discussion of the factors which may influence the rate of payments
(including prepayments) of the Mortgage Loans, see ' -- Prepayment
Considerations and Risks' herein and 'Yield and Prepayment Considerations' in
the Prospectus.
 
     In general, the weighted average lives of the Offered Certificates will be
shortened if the level of prepayments of principal of the related Mortgage Loans
increases. However, the weighted average lives of the Offered Certificates will
depend upon a variety of other factors, including the timing of changes in such
rate of principal payments and the priority sequence of distributions of
principal of the Classes of Certificates. See 'Description of the
Certificates -- Principal' herein.
 
     The interaction of the foregoing factors may have different effects on
various Classes of Offered Certificates and the effects on any Class may vary at
different times during the life of such Class. Accordingly, no assurance can be
given as to the weighted average life of any Class of Offered Certificates.
Further, to the extent the prices of the Offered Certificates represent
discounts or premiums to their respective original Class Certificate Balances,
variability in the weighted average lives of such Classes of Offered
Certificates will result in variability in the related yields to maturity. For
an example of how the weighted average lives of the Classes of Offered
Certificates may be affected at various constant Prepayment Assumptions, see the
Decrement Tables below.
 
DECREMENT TABLES
 
     The following tables indicate the percentages of the initial Class
Certificate Balances of the Classes of Offered Certificates (other than the
Notional Amount Certificates) that would be outstanding after each of the dates
shown at various constant Prepayment Assumptions and the corresponding weighted
average lives of such Classes. The tables have been prepared on the basis of the
Structuring Assumptions. It is not likely that (i) all of
 
                                      S-44
 

<PAGE>
<PAGE>

the Mortgage Loans in a Loan Group will have the characteristics assumed, (ii)
all of the Mortgage Loans will prepay at the constant Prepayment Assumption
specified in the tables or at any constant rate or (iii) all of the Mortgage
Loans will prepay at the same rate. Moreover, the diverse remaining terms to
maturity of the Mortgage Loans could produce slower or faster principal
distributions than indicated in the tables at the specified constant Prepayment
Assumptions, even if the weighted average remaining term to maturity of the
Mortgage Loans in a Loan Group is consistent with the remaining terms to
maturity of the Mortgage Loans specified in the Structuring Assumptions.

LAST SCHEDULED DISTRIBUTION DATE
 
     The Last Scheduled Distribution Date for each Class of Offered Certificates
is the Distribution Date in September 2028 which is the Distribution Date in the
month immediately following the month of the latest scheduled maturity date for
any of the Mortgage Loans. Since the rate of distributions in reduction of the
Class Certificate Balance or Notional Amount of each Class of Offered
Certificates will depend on the rate of payment (including prepayments) of the
Mortgage Loans in the related Loan Group, with respect to the Senior
Certificates, and all of the Mortgage Loans, with respect to the Subordinated
Certificates, the Class Certificate Balance or Notional Amount of any such Class
could be reduced to zero significantly earlier or later than the Last Scheduled
Distribution Date. The rate of payments on the Mortgage Loans will depend on
their particular characteristics, as well as on prevailing interest rates from
time to time and other economic factors, and no assurance can be given as to the
actual payment experience of the Mortgage Loans. See ' -- Prepayment
Considerations and Risks' and ' -- Weighted Average Lives of the Offered
Certificates' herein and 'Yield and Prepayment Considerations' in the
Prospectus.
 
THE SUBORDINATED CERTIFICATES
 
     The weighted average lives of, and the yields to maturity on, the
Subordinated Certificates, in increasing order of their numerical Class
designations, will be progressively more sensitive to the rate and timing of
mortgagor defaults and the severity of ensuing losses on the Mortgage Loans. If
the actual rate and severity of losses on the Mortgage Loans is higher than
those assumed by a holder of a Subordinated Certificate, the actual yield to
maturity of such Certificate may be lower than the yield expected by such holder
based on such assumption. The timing of losses on the Mortgage Loans will also
affect an investor's actual yield to maturity, even if the rate of defaults and
severity of losses over the life of the Mortgage Pool are consistent with an
investor's expectations. In general, the earlier a loss occurs, the greater the
effect on an investor's yield to maturity. Realized Losses on the Mortgage Loans
will reduce the Class Certificate Balances of the applicable Class of
Subordinated Certificates to the extent of any losses allocated thereto (as
described under 'Description of the Certificates -- Allocation of Losses'),
without the receipt of cash attributable to such reduction. In addition,
shortfalls in cash available for distributions on the Subordinated Certificates
will result in a reduction in the Class Certificate Balance of the Class of
Subordinated Certificates then outstanding with the highest numerical Class
designation if and to the extent that the aggregate of the Class Certificate
Balances of all Classes of Certificates, following all distributions and the
allocation of Realized Losses on a Distribution Date, exceeds the Pool Principal
Balance as of the Due Date occurring in the month of such Distribution Date. As
a result of such reductions, less interest will accrue on such Class of
Subordinated Certificates than otherwise would be the case. The yields to
maturity of the Subordinated Certificates will also be affected by the
disproportionate allocation of principal prepayments to the Senior Certificates,
the allocation to the Class A Certificates of the Non-PO Formula Principal
Amount of a Loan Group for which the Senior Depletion Date has occurred, Net
Interest Shortfalls, other cash shortfalls in Available Funds and distribution
of funds to the Class PO Certificateholders otherwise available for distribution
on the Subordinated Certificates to the extent of reimbursement for Class PO
Deferred Amounts. See 'Description of the Certificates -- Principal' and
' -- Allocation of Losses' herein.
 
     If on any Distribution Date the Applicable Credit Support Percentage for
any Class of Subordinated Certificates is less than its Original Applicable
Credit Support Percentage, all partial principal prepayments and principal
prepayments in full available for distribution on the Subordinated Certificates
will be allocated solely to all other Classes of Subordinated Certificates with
lower numerical designations, thereby accelerating the amortization thereof
relative to that of the Restricted Classes and reducing the weighted average
lives of such Classes of Subordinated Certificates receiving such distributions.
Accelerating the amortization of the Classes of Subordinated Certificates with
lower numerical Class designations relative to the other Classes of Subordinated
Certificates is intended to preserve the availability of the subordination
provided by such other Classes.
 
                               CREDIT ENHANCEMENT
 
SUBORDINATION OF CERTAIN CLASSES
 
     The rights of the holders of the Subordinated Certificates to receive
distributions with respect to the Mortgage Loans will be subordinated to such
rights of the holders of the Senior Certificates, and the rights of the holders
of each Class of Subordinated Certificates (other than the Class B-1
Certificates) to receive such
 
                                      S-55
 

<PAGE>
<PAGE>

distributions will be further subordinated to such rights of the holders of the
Class or Classes of Subordinated Certificates with lower numerical Class
designations, in each case only to the extent described herein. The
subordination of the Subordinated Certificates to the Senior Certificates and
the further subordination within the Subordinated Certificates is intended to
provide holders of Certificates with a higher relative payment priority
protection against Realized Losses other than Excess Losses. In addition, the
Subordinated Certificates will provide limited protection against Special Hazard
Losses, Bankruptcy Losses and Fraud Losses up to the applicable Special Hazard
Loss Coverage Amount, Bankruptcy Loss Coverage Amount and Fraud Loss Coverage
Amount, respectively, as described below. The applicable Non-PO Percentage of
Realized Losses, other than Excess Losses, will be allocated to the Class of
Subordinated Certificates then outstanding with the highest numerical Class
designation. In addition, the Class Certificate Balance of such Class of
Subordinated Certificates will be reduced by the amount of distributions on the
Class PO Certificates in reimbursement for Class PO Deferred Amounts.
 
     Because Subordinated Certificates are available to cover losses on Mortgage
Loans in all Loan Groups, disproportionate losses in one Loan Group will deplete
the protection that would otherwise be provided to the Classes of Senior
Certificates relating to the other Senior Certificate Groups. As a result, the
protection provided to Senior Certificates of a Senior Certificate Group by the
Subordinated Certificates may be decreased even in the absence of losses in the
related Loan Group.
 
     The Subordinated Certificates will provide protection to the Classes of
Certificates of higher relative priority against (i) Special Hazard Losses in an
initial amount expected to be up to approximately $8,502,777 (the 'Special
Hazard Loss Coverage Amount'), (ii) Bankruptcy Losses in an initial amount
expected to be up to approximately $242,113 (the 'Bankruptcy Loss Coverage
Amount') and (iii) Fraud Losses in an initial amount expected to be up to
approximately $17,005,553 (the 'Fraud Loss Coverage Amount').
 
     The Special Hazard Loss Coverage Amount will be reduced, from time to time,
to be an amount equal on any Distribution Date to the lesser of (a) the greatest
of (i) 1% of the aggregate of the principal balances of the Mortgage Loans, (ii)
twice the principal balance of the largest Mortgage Loan and (iii) the aggregate
principal balances of the Mortgage Loans secured by Mortgaged Properties located
in the single California postal zip code area having the highest aggregate
principal balance of any such zip code area and (b) the Special Hazard Loss
Coverage Amount as of the Closing Date less the amount, if any, of losses
attributable to Special Hazard Mortgage Loans incurred since the Closing Date.
All principal balances for the purpose of this definition will be calculated as
of the first day of the month preceding such Distribution Date after giving
effect to scheduled installments of principal and interest on the Mortgage Loans
then due, whether or not paid.
 
     The Fraud Loss Coverage Amount will be reduced, from time to time, by the
amount of Fraud Losses allocated to the Certificates. In addition, on each
anniversary of the Cut-off Date, the Fraud Loss Coverage Amount will be reduced
as follows: (a) on the first, second, third and fourth anniversaries of the
Cut-off Date, to an amount equal to the lesser of (i) 1% of the then current
Pool Principal Balance and (ii) the excess of the Fraud Loss Coverage Amount as
of the preceding anniversary of the Cut-off Date (or, in the case of the first
such anniversary, as of the Cut-off Date) over the cumulative amount of Fraud
Losses allocated to the Certificates since such preceding anniversary or the
Cut-off Date, as the case may be, and (b) on the fifth anniversary of the
Cut-off Date, to zero.
 
     The Bankruptcy Loss Coverage Amount will be reduced, from time to time, by
the amount of Bankruptcy Losses allocated to the Certificates.
 
     The amount of coverage provided by the Subordinated Certificates for
Special Hazard Losses, Bankruptcy Losses and Fraud Losses may be cancelled or
reduced from time to time for each of the risks covered, provided that the then
current ratings of the Certificates assigned by the Rating Agencies are not
adversely affected thereby. In addition, a reserve fund or other form of credit
enhancement may be substituted for the protection provided by the Subordinated
Certificates for Special Hazard Losses, Bankruptcy Losses and Fraud Losses.
 
     As used herein, a 'Deficient Valuation' is a bankruptcy proceeding whereby
the bankruptcy court may establish the value of the Mortgaged Property at an
amount less than the then outstanding principal balance of the Mortgage Loan
secured by such Mortgaged Property or may reduce the outstanding principal
balance of a Mortgage Loan. In the case of a reduction in the value of the
related Mortgaged Property, the amount of the secured debt could be reduced to
such value, and the holder of such Mortgage Loan thus would become an unsecured
creditor to the extent the outstanding principal balance of such Mortgage Loan
exceeds the value so
 
                                      S-56

assigned to the Mortgaged Property by the bankruptcy court. In addition, certain
other modifications of the terms of a Mortgage Loan can result from a bankruptcy
proceeding, including the reduction (a 'Debt Service Reduction') of the amount
of the monthly payment on the related Mortgage Loan. Notwithstanding the
foregoing, no such occurrence shall be considered a Debt Service Reduction or
Deficient Valuation so long as the Master Servicer is pursuing any other
remedies that may be available with respect to the related Mortgage Loan and (i)
such Mortgage Loan is not in default with respect to payment due thereunder or
(ii) scheduled monthly payments of principal and interest are being advanced by
the Master Servicer without giving effect to any Debt Service Reduction or
Deficient Valuation.
 
                      THE POOLING AND SERVICING AGREEMENT
 
EVENTS OF DEFAULT
 
     Events of Default under the Agreement will consist of (i) any failure by
the Master Servicer to deposit in the Certificate Account or remit to the
Trustee any payment which continues unremedied for five days after the giving of
written notice of such failure to the Master Servicer by the Trustee or the
Depositor, or to the Master Servicer and the Trustee by the holders of
Certificates having not less than 25% of the Voting Rights evidenced by the
Certificates; (ii) any failure by the Master Servicer to observe or perform in
any material respect any of its other covenants or agreements in the Agreement
which failure materially affects the rights of Certificateholders that continues
unremedied for sixty days after the giving of written notice of such failure to
the Master Servicer by the Trustee or the Depositor, or to the Master Servicer
and the Trustee by the holders of Certificates of any Class evidencing not less
than 25% of the Voting Rights evidenced by the Certificate; and (iii) certain
events of insolvency, readjustment of debt, marshalling of assets and
liabilities or similar proceeding and certain actions by or on behalf of the
Master Servicer indicating its insolvency, reorganization or inability to pay
its obligations as described in the Agreement. 'Voting Rights' are the portion
of voting rights of all of the Certificates which is allocated to any
Certificate pursuant to the terms of the Agreement.
 
AMENDMENT OF AGREEMENT
 
     The 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 any defective provision therein or to
supplement any provision therein which may be inconsistent with any other
provision therein; (iii) to add to the duties of the Depositor, the Seller or
the Master Servicer; (iv) to add any other provisions with respect to matters or
questions arising thereunder; or (v) to modify, alter, amend, add to or rescind
any of the terms or provisions contained in the Agreement; provided, however,
that any action pursuant to clauses (iv) or (v) will not, as evidenced by an
opinion of counsel, adversely affect in any material respect the interests of
any Certificateholder; provided, further, that no such opinion of counsel will
be required if the person requesting such amendment obtains a letter from each
Rating Agency stating that such amendment will not result in the downgrading or
withdrawal of the respective ratings then assigned to such Certificates. In
addition, the Agreement may be amended without the consent of any of the
Certificateholders (i) to modify, eliminate or add to any of its provisions to
such extent as may be necessary or helpful to maintain the qualification of the
Trust Fund as a REMIC or to avoid or minimize the risk of imposition of any tax
on the REMIC, or (ii) to comply with any other requirements of the Code,
provided that the Trustee has received an opinion of counsel to the effect that
such action is necessary or helpful to maintain such qualification, avoid or
minimize such risk or comply with such requirements, as applicable. The
Agreement may also be amended by the Depositor, the Master Servicer and the
Trustee with the consent of holders of Certificates evidencing a majority in
interest 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 that no such amendment may (i) reduce in any
manner the amount of, or delay the timing of, payments that are required to be
distributed on any Certificate without the consent of the holder of such
Certificate, (ii) adversely affect in any material respect the interests of the
holders of any Class of Certificates in a manner other than as described in (i),
without the consent of the holders of Certificates of such Class evidencing, as
to such Class, percentage interests aggregating 66%, (iii) reduce the aforesaid
percentage of Certificates of any Class of holders that is required to consent
to any such amendment without the consent of the holders of all Certificates of
such Class covered by the Agreement then outstanding. The Trustee will not be
entitled to consent to an amendment to the Agreement without having first
received an
 
                                      S-57
 

<PAGE>
<PAGE>

opinion of counsel to the effect that such amendment will not cause such Trust
Fund to fail to qualify as a REMIC.
 
LIST OF CERTIFICATEHOLDERS
 
     The Agreement will provide that three or more Certificateholders may, by
written request to the Trustee, obtain access to the list of all
Certificateholders maintained by the Trustee for the purpose of communicating
with other Certificateholders with respect to their rights under the Agreement
and the Certificates.
 
                                USE OF PROCEEDS
 
     The Depositor will apply the net proceeds of the sale of the Certificates
against the purchase price of the Mortgage Loans.
 
                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     For federal income tax purposes, an election will be made to treat the
Trust Fund as a REMIC.
 
     The Regular Certificates generally will be treated as debt instruments
issued by the REMIC for federal income tax purposes. Income on the Regular
Certificates must be reported under an accrual method of accounting.
 
     The Principal Only Certificates will be treated for federal income tax
purposes as having been issued with an amount of original issue discount ('OID')
equal to the difference between their principal balance and their issue price.
Although the tax treatment is not entirely certain, Notional Amount Certificates
will be treated as having been issued with OID for federal income tax purposes
equal to the excess of all expected payments of interest on such Certificates
over their issue price. Although unclear, a holder of a Notional Amount
Certificate may be entitled to deduct a loss to the extent that its remaining
basis exceeds the maximum amount of future payments to which such
Certificateholder would be entitled if there were no further prepayments of the
Mortgage Loans. The remaining Classes of Regular Certificates, depending on
their respective issue prices (as described in the Prospectus under 'Federal
Income Tax Consequences'), may be treated as having been issued with OID for
federal income tax purposes. For purposes of determining the amount and rate of
accrual of OID and market discount, the Trust Fund intends to assume that there
will be prepayments on the Mortgage Loans at a rate equal to 100% of the
Prepayment Assumption. No representation is made as to whether the Mortgage
Loans will prepay at either of the foregoing rates or any other rate. See
'Yield, Prepayment and Maturity Considerations' herein and 'Federal Income Tax
Consequences' in the Prospectus. Computing accruals of OID in the manner
described in the Prospectus may (depending on the actual rate of prepayments
during the accrual period) result in the accrual of negative amounts of OID on
the Certificates issued with OID in an accrual period. Holders will be entitled
to offset negative accruals of OID only against future OID accrual on such
Certificates.
 
     If the holders of any Regular Certificates are treated as holding such
Certificates at a premium, such holders should consult their tax advisors
regarding the election to amortize bond premium and the method to be employed.
 
     As is described more fully under 'Federal Income Tax Consequences' in the
Prospectus, the Offered Certificates will represent qualifying assets under
Sections 856(c)(4)(A) and 7701(a)(19)(C) of the Code, and net interest income
attributable to the Offered Certificates will be 'interest on obligations
secured by mortgages on real property' within the meaning of Section
856(c)(3)(B) of the Code, to the extent the assets of the Trust Fund are assets
described in such sections. The Regular Certificates will represent qualifying
assets under Section 860G(a)(3) if acquired by a REMIC within the prescribed
time periods of the Code.
 
     The holders of the Residual Certificates must include the taxable income of
the REMIC in their federal taxable income. The resulting tax liability of the
holders may exceed cash distributions to such holders during certain periods.
All or a portion of the taxable income from a Residual Certificate recognized by
a holder may be treated as 'excess inclusion' income, which, with limited
exceptions, is subject to U.S. federal income tax.
 
     The Small Business Job Protection Act of 1996 has eliminated the special
rule permitting Section 593 institutions ('thrift institutions') to use net
operating losses and other allowable deductions to offset their excess inclusion
income from REMIC residual certificates that have 'significant value' within the
meaning of the
 
                                      S-58
 

<PAGE>
<PAGE>

REMIC Regulations, effective for taxable years beginning after December 31,
1995, except with respect to residual certificates continuously held by a thrift
institution since November 1, 1995.
 
     In addition, the Small Business Job Protection Act of 1996 provides three
rules for determining the effect on excess inclusions on the alternative minimum
taxable income of a residual holder. First, alternative minimum taxable income
for such residual holder is determined without regard to the special rule that
taxable income cannot be less than excess inclusions. Second, a residual
holder's alternative minimum taxable income for a tax year cannot be less than
the excess inclusions for the year. Third, the amount of any alternative minimum
tax net operating loss deductions must be computed without regard to any excess
inclusions. These rules are effective for tax years beginning after December
31, 1986, unless a residual holder elects to have such rules apply only to tax
years beginning after August 20, 1996.
 
     Furthermore, the Small Business Job Protection Act of 1996, as part of the
repeal of the bad debt reserve method for thrift institutions, repealed the
application of Code Section 593(d) to any taxable year beginning after December
31, 1995.
 
     Also, purchasers of a Residual Certificate should consider carefully the
tax consequences of an investment in Residual Certificates discussed in the
Prospectus and should consult their own tax advisors with respect to those
consequences. See 'Federal Income Tax Consequences -- Taxation of Holders of
Residual Interest Securities' in the Prospectus. Specifically, prospective
holders of Residual Certificates should consult their tax advisors regarding
whether, at the time of acquisition, a Residual Certificate will be treated as a
'noneconomic' residual interest, a 'non-significant value' residual interest and
a 'tax avoidance potential' residual interest. See 'Federal Income Tax
Consequences -- Taxation of Holders of Residual Interest
Securities -- Restrictions on Ownership and Transfer of Residual Interest
Securities' and 'Federal Income Tax Consequences -- Tax Treatment of Foreign
Investors' in the Prospectus. Additionally, for information regarding Prohibited
Transactions and Treatment of Realized Losses, see 'Federal Income Tax
Consequences -- Taxation of the REMIC -- Prohibited Transactions and
Contributions Tax' and 'Federal Income Tax Consequences -- Taxation of Residual
Interest Securities -- Limitations on Losses' in the Prospectus.
 
                              ERISA CONSIDERATIONS
 
     Any plan fiduciary which proposes to cause a Plan (as defined below) to
acquire any of the Offered Certificates should consult with its counsel with
respect to the potential consequences under the Employee Retirement Income
Security Act of 1974, as amended ('ERISA'), and/or the Code, of the Plan's
acquisition and ownership of such Certificates. See 'ERISA Considerations' in
the Prospectus. Section 406 of ERISA prohibits 'parties in interest' with
respect to an employee benefit plan subject to ERISA and/or the excise tax
provisions set forth under Section 4975 of the Code (a 'Plan') from engaging in
certain transactions involving such Plan and its assets unless a statutory or
administrative exemption applies to the transaction. Section 4975 of the Code
imposes certain excise taxes on prohibited transactions involving Plans and
other arrangements (including, but not limited to, individual retirement
accounts) described under that Section; ERISA authorizes the imposition of civil
penalties for prohibited transactions involving Plans not subject to the
requirements of Section 4975 of the Code.
 
     Certain employee benefit plans, including governmental plans and certain
church plans, are not subject to ERISA's requirements. Accordingly, assets of
such plans may be invested in the Offered Certificates without regard to the
ERISA considerations described herein and in the Prospectus, subject to the
provisions of other applicable federal and state law. Any such plan that is
qualified and exempt from taxation under Sections 401(a) and 501(a) of the Code
may nonetheless be subject to the prohibited transaction rules set forth in
Section 503 of the Code.
 
     Except as noted above, investments by Plans are subject to ERISA's general
fiduciary requirements, including the requirement of investment prudence and
diversification and the requirement that a Plan's investments be made in
accordance with the documents governing the Plan. A fiduciary that decides to
invest the assets of a Plan in the Offered Certificates should consider, among
other factors, the extreme sensitivity of the investment to the rate of
principal payments (including prepayments) on the Mortgage Loans.
 
     The U.S. Department of Labor has granted individual administrative
exemptions to Merrill Lynch, Pierce, Fenner & Smith Incorporated (Prohibited
Transaction Exemption 90-29, as amended, Exemption Application No. D-8012, 55
Fed. Reg. 21459 (1990)), PaineWebber Incorporated (Prohibited Transaction
Exemption 90-36, as amended, Exemption Application No. D-8069, 55 Fed. Reg.
25903 (1990)) and to Lehman Brothers Inc.
 
                                      S-59

<PAGE>

(Prohibited Transaction Exemption 91-14, as amended, Exemption Application No.
D-7958, 58 Fed. Reg. 7413 (1991)) (collectively, the 'Exemptions'), from certain
of the prohibited transaction rules of ERISA and the related excise tax
provisions of Section 4975 of the Code with respect to the initial purchase, the
holding and the subsequent resale by Plans of certificates in pass-through
trusts that consist of certain receivables, loans and other obligations that
meet the conditions and requirements of the Exemptions. The Exemptions apply to
mortgage loans such as the Mortgage Loans in the Trust Fund.
 
     For a general description of the Exemptions and the conditions that must be
satisfied for the Exemptions to apply, see 'ERISA Considerations' in the
Prospectus.
 
     It is expected that the Exemptions will apply to the acquisition and
holding by Plans of the Class A Certificates (other than the Class A-R
Certificates) and that all conditions of the Exemptions other than those within
the control of the investors will be met. In addition, as of the date hereof,
there is no single Mortgagor that is the obligor on five percent (5%) of the
Mortgage Loans included in the Trust Fund by aggregate unamortized principal
balance of the assets of the Trust Fund. Because the Class PO and Class X
Certificates are not being purchased by any Underwriter, such Classes of
Certificates do not currently meet the requirements of the Exemptions or any
comparable individual administrative exemption granted to any Underwriter.
Consequently, the sale or exchange of the Class PO and Class X Certificates may
be made only under the conditions set forth for the Class A-R, Class B-1, Class
B-2 and Class B-3 Certificates in clauses (i) or (iii) below.
 
     BECAUSE THE CHARACTERISTICS OF THE CLASS A-R, CLASS B-1, CLASS B-2 AND
CLASS B-3 CERTIFICATES WILL NOT MEET THE REQUIREMENTS OF PTCE 83-1 (AS DESCRIBED
IN THE PROSPECTUS) OR THE EXEMPTIONS AND MAY NOT MEET THE REQUIREMENTS OF ANY
OTHER ISSUED EXEMPTION UNDER ERISA, THE PURCHASE AND HOLDING OF THE CLASS A-R,
CLASS B-1, CLASS B-2 AND CLASS B-3 CERTIFICATES BY A PLAN OR BY INDIVIDUAL
RETIREMENT ACCOUNTS OR OTHER PLANS SUBJECT TO SECTION 4975 OF THE CODE MAY
RESULT IN PROHIBITED TRANSACTIONS OR THE IMPOSITION OF EXCISE TAXES OR CIVIL
PENALTIES. CONSEQUENTLY, TRANSFERS OF THE CLASS A-R, CLASS B-1, CLASS B-2 AND
CLASS B-3 CERTIFICATES WILL NOT BE REGISTERED BY THE TRUSTEE UNLESS THE TRUSTEE
RECEIVES: (I) A REPRESENTATION FROM THE TRANSFEREE OF SUCH CERTIFICATE,
ACCEPTABLE TO AND IN FORM AND SUBSTANCE SATISFACTORY TO THE TRUSTEE, TO THE
EFFECT THAT SUCH TRANSFEREE IS NOT AN EMPLOYEE BENEFIT PLAN SUBJECT TO SECTION
406 OF ERISA OR A PLAN OR ARRANGEMENT SUBJECT TO SECTION 4975 OF THE CODE, NOR A
PERSON ACTING ON BEHALF OF ANY SUCH PLAN OR ARRANGEMENT USING THE ASSETS OF ANY
SUCH PLAN OR ARRANGEMENT TO EFFECT SUCH TRANSFER; (II) IF THE PURCHASER IS AN
INSURANCE COMPANY, A REPRESENTATION THAT THE PURCHASER IS AN INSURANCE COMPANY
WHICH IS PURCHASING SUCH CERTIFICATES WITH FUNDS CONTAINED IN AN 'INSURANCE
COMPANY GENERAL ACCOUNT' (AS SUCH TERM IS DEFINED IN SECTION V(E) OF PROHIBITED
TRANSACTION CLASS EXEMPTION ('PTCE') 95-60) AND THAT THE PURCHASE AND HOLDING OF
SUCH CERTIFICATES ARE COVERED UNDER SECTIONS I AND III OF PTCE 95-60; OR (III)
AN OPINION OF COUNSEL SATISFACTORY TO THE TRUSTEE THAT THE PURCHASE OR HOLDING
OF SUCH CERTIFICATE BY A PLAN, ANY PERSON ACTING ON BEHALF OF A PLAN OR USING
SUCH PLAN'S ASSETS, WILL NOT RESULT IN THE ASSETS OF THE TRUST FUND BEING DEEMED
TO BE 'PLAN ASSETS' AND SUBJECT TO THE PROHIBITED TRANSACTION REQUIREMENTS OF
ERISA AND THE CODE AND WILL NOT SUBJECT THE TRUSTEE TO ANY OBLIGATION IN
ADDITION TO THOSE UNDERTAKEN IN THE AGREEMENT. SUCH REPRESENTATION AS DESCRIBED
ABOVE SHALL BE DEEMED TO HAVE BEEN MADE TO THE TRUSTEE BY THE TRANSFEREE'S
ACCEPTANCE OF A CLASS B-1, CLASS B-2 OR CLASS B-3 CERTIFICATE. IN THE EVENT THAT
SUCH REPRESENTATION IS VIOLATED, OR ANY ATTEMPT TO TRANSFER TO A PLAN OR TO A
PERSON ACTING ON BEHALF OF A PLAN OR USING A PLAN'S ASSETS IS ATTEMPTED WITHOUT
SUCH OPINION OF COUNSEL, SUCH ATTEMPTED TRANSFER OR ACQUISITION SHALL BE VOID
AND OF NO EFFECT.
 
     Prospective Plan investors should consult with their legal advisors
concerning the impact of ERISA and the Code, the applicability of the
Exemptions, and the potential consequences in their specific circumstances,
prior to making an investment in the Offered Certificates. Moreover, each Plan
fiduciary should determine whether under the general fiduciary standards of
investment prudence and diversification, an investment in the Offered
Certificates is appropriate for the Plan, taking into account the overall
investment policy of the Plan and the composition of the Plan's investment
portfolio.

                             METHOD OF DISTRIBUTION
 
     Subject to the terms and conditions set forth in the Underwriting Agreement
between the Depositor, Merrill Lynch, Pierce, Fenner & Smith Incorporated
('Merrill Lynch'), PaineWebber Incorporated ('PaineWebber') and Lehman Brothers
Inc. (the 'Subordinated Certificate Underwriter' and, together with Merrill
Lynch and PaineWebber, the 'Underwriters'), the Depositor has agreed to sell to
the Underwriters, and each Underwriter has agreed to purchase from the
Depositor, the Classes of Underwritten Certificates indicated on the cover page
hereof to be purchased by it. Distribution of the Merrill Lynch Underwritten
Senior Certificates will be made by Merrill Lynch, distribution of the
PaineWebber Underwritten Senior Certificates will be made by PaineWebber and
distribution of the Underwritten Subordinated Certificates will be made by the
Subordinated Certificate Underwriter, in each case from time to time in
negotiated transactions or otherwise at varying prices to be determined at the
time of sale. In connection with the sale of the Underwritten Certificates, the
Underwriters may be deemed to have received compensation from the Depositor in
the form of underwriting discounts.
 
     Merrill Lynch intends to make a secondary market in the Merrill Lynch
Underwritten Senior Certificates, PaineWebber intends to make a secondary market
in the PaineWebber Underwritten Senior Certificates and the Subordinated
Certificate Underwriter intends to make a secondary market in the Underwritten
Subordinated Certificates, but no Underwriter has any obligation to do so. There
can be no assurance that a secondary market for the Offered Certificates will
develop or, if it does develop, that it will continue or that it will provide
Certificateholders with a sufficient level of liquidity of investment.
 
     The Depositor has agreed to indemnify the Underwriters against, or make
contributions to the Underwriters with respect to, certain liabilities,
including liabilities under the Securities Act of 1933, as amended.
 
     The Class PO and Class X Certificates may be offered by the Seller from
time to time directly or through underwriters or agents (either of which may
include Countrywide Securities Corporation, an affiliate of the Depositor, the
Seller and the Master Servicer) in one or more negotiated transactions, or
otherwise, at varying prices to be determined at the time of sale, in one or
more separate transactions. Any underwriters or agents that participate in the
distribution of the Class PO and Class X Certificates may be deemed to be
'underwriters' within the meaning of the Securities Act of 1933, as amended, and
any profit on the sale of such Certificates, discounts, commissions, concessions
or other compensation received by any such underwriter or agent may be deemed to
be underwriting discounts and commissions under such Act.
 
                                 LEGAL MATTERS
 
     The validity of the Certificates, including certain federal income tax
consequences with respect thereto, will be passed upon for the Depositor by
Brown & Wood LLP, New York, New York. Stroock & Stroock & Lavan LLP, New York,
New York, will pass upon certain legal matters on behalf of the Underwriters.
 
                                    RATINGS
 
     It is a condition of the issuance of the Senior Certificates that they be
rated AAA by Duff & Phelps Credit Rating Company ('DCR') and that the Senior
Certificates, other than the Class PO-1, Class PO-2, Class PO-3, Class X-1,
Class X-2 and Class X-3 Certificates, be rated AAA by Standard & Poor's, a
division of The McGraw-Hill Companies, Inc. ('S&P') and, together with DCR, the
'Rating Agencies'). It is a condition to the issuance of the Class PO-1, Class
PO-2, Class PO-3, Class X-1, Class X-2 and Class X-3 Certificates that they be
rated AAAr by S&P. It is a condition of the issuance of the Class B-1, Class B-2
and Class B-3 Certificates that they be rated at least AA, A and BBB,
respectively, by DCR.
 
     The ratings assigned by DCR to mortgage pass-through certificates address
the likelihood of the receipt by certificateholders of all distributions to
which they are entitled under the transaction structure. DCR's ratings reflect
its analysis of the riskiness of the mortgage loans and its analysis of the
structure of the transaction as set forth in the operative documents. DCR's
ratings do not address the effect on the certificates' yield attributable to
prepayments or recoveries on the underlying mortgage loans. Further, the ratings
on the Class X-1, Class X-2 and Class X-3 Certificates do not address whether
investors will recoup their initial investment. The rating assigned by DCR to
the Class PO-1, Class PO-2 and Class PO-3 Certificates only addresses the return
of its Class Certificate Balance. The rating assigned by DCR to the Class A-R
Certificates only addresses the return of its Class Certificate Balance and
interest thereon at its stated Pass-Through Rate.
 
                                      S-61
 

<PAGE>
<PAGE>

     The ratings assigned by S&P to mortgage pass-through certificates address
the likelihood of the receipt of all distributions on the mortgage loans by the
related Certificateholders under the agreements pursuant to which such
certificates are issued. S&P's ratings take into consideration the credit
quality of the related mortgage pool, including any credit support providers,
structural and legal aspects associated with such certificates, and the extent
to which the payment stream on such mortgage pool is adequate to make payments
required by such certificates. S&P's ratings on such certificates do not,
however, constitute a statement regarding frequency of prepayments on the
related mortgage loans. The 'r' symbol is appended to the rating by S&P of those
Certificates that S&P believes may experience high volatility or high
variability in expected returns due to non-credit risks. The absence of an 'r'
symbol in the ratings of the other Offered Certificates should not be taken as
an indication that such Certificates will exhibit no volatility or variability
in total return.
 
     The ratings of the Rating Agencies do not address the possibility that, as
a result of principal prepayments, Certificateholders may receive a lower than
anticipated yield.
 
     The ratings assigned to the Offered Certificates should be evaluated
independently from similar ratings on other types of securities. A rating is not
a recommendation to buy, sell or hold securities and may be subject to revision
or withdrawal at any time by the Rating Agencies.
 
     The Depositor has not requested a rating of the Offered Certificates by any
rating agency other than the Rating Agencies; there can be no assurance,
however, as to whether any other rating agency will rate the Offered
Certificates or, if it does, what rating would be assigned by such other rating
agency. The rating assigned by such other rating agency to the Offered
Certificates could be lower than the respective ratings assigned by the Rating
Agencies.

PROSPECTUS
 
                                  CWABS, INC.
                                   Depositor
                            Asset Backed Securities
                              (Issuable in Series)
                         ------------------------------
 
     This Prospectus relates to the issuance of Asset Backed Certificates (the
'Certificates') and Asset Backed Notes (the 'Notes' and, together with the
Certificates, the 'Securities'), which may be sold from time to time in one or
more series (each, a 'Series') by CWABS, Inc. (the 'Depositor') or by a Trust
Fund (as defined below) on terms determined at the time of sale and described in
this Prospectus and the related Prospectus Supplement. The Securities of a
Series will consist of Certificates which evidence beneficial ownership of a
trust established by the Depositor (each, a 'Trust Fund'), and/or Notes secured
by the assets of a Trust Fund. As specified in the related Prospectus
Supplement, the Trust Fund for a Series of Securities will include certain
assets (the 'Trust Fund Assets') which will consist of the following types of
mortgage loans (the 'Loans'): (i) mortgage loans secured by first and/or
subordinate liens on one- to four-family residential properties, including
manufactured housing that is permanently affixed and treated as real property
under local law, or security interests in shares issued by cooperative housing
corporations (the 'Single Family Loans'), (ii) mortgage loans secured by first
and/or subordinate liens on small multifamily residential properties, such as
rental apartment buildings or projects containing five to fifty residential
units (the 'Multifamily Loans'), (iii) closed-end and/or revolving home equity

                                            As specified in the related Prospectus Supplement, the Home Equity
                                            Loans will, and the Home Improvement Contracts may, be secured by
                                            mortgages or deeds of trust or other similar security instruments
                                            creating a lien on a Mortgaged Property, which may be subordinated to

                                            in accordance with a schedule or formula or on the basis of

                                            such events occur, in each case as specified in the related
                                            Prospectus Supplement. The timing and amounts of such distributions
                                            may vary among classes or over time, as specified in the related
                                            Prospectus Supplement.
Distributions on the Securities...........  Distributions on the Securities entitled thereto will be made
                                            monthly, quarterly, semi-annually or at such other intervals and on
                                            the dates specified in the related Prospectus Supplement (each, a
                                            'Distribution Date') out of the payments received in respect of the
                                            assets of the related Trust Fund or Funds or other assets pledged for
                                            the benefit of the Securities as described under 'Credit Enhancement'
                                            herein to the extent specified in the related Prospectus Supplement.
                                            The amount allocable to payments of principal and interest on any
                                            Distribution Date will be determined as specified in the related
                                            Prospectus Supplement. The Prospectus Supplement for a Series of
                                            Securities will describe the method for allocating distributions
                                            among Securities of different classes as well as the method for
                                            allocating distributions among Securities for any particular class.
                                            Unless otherwise specified in the related Prospectus Supplement, the
                                            aggregate original principal balance of the Securities will not
                                            exceed the aggregate distributions allocable to principal that such
                                            Securities will be entitled to receive. If specified in the related
                                            Prospectus Supplement, the Securities will have an aggregate original
                                            principal balance equal to the aggregate unpaid principal balance of
                                            the Trust Fund Assets as of the related Cut-off Date and will bear
                                            interest in the aggregate at a rate equal to the interest rate borne
                                            by the underlying Loans (the 'Loan Rate') net of the aggregate
                                            servicing fees and any other amounts specified in the related
                                            Prospectus Supplement (the 'Pass-Through Rate') or at such other
                                            interest rate as may be specified in such Prospectus Supplement. If
                                            specified in the related Prospectus Supplement, the aggregate
                                            original principal balance of the Securities and interest rates on
                                            the classes of Securities will be determined based on the cash flow
                                            on the Trust Fund Assets.
                                            The rate at which interest will be passed through or paid to holders
                                            of each class of Securities entitled thereto may be a fixed rate or a
                                            rate that is subject to change from time to time from the time and
                                            for the periods, in each case, as specified in the related Prospectus
                                            Supplement. Any such rate may be calculated on a loan-by-loan,
                                            weighted average or notional amount in each case as described in the
                                            related Prospectus Supplement.
Credit Enhancement........................  The assets in a Trust Fund or the Securities of one or more classes
                                            in the related Series may have the benefit of one or more types of
                                            credit enhancement as described in the related Prospectus Supplement.
                                            The protection against losses afforded by any such credit support may
                                            be limited. The type, characteristics and amount of credit
                                            enhancement will be determined based on the characteristics of the
                                            Loans comprising the Trust Fund Assets and other factors and will be
                                            established on the basis of requirements of each Rating Agency rating
                                            the Securities of such Series. See 'Credit Enhancement.'

A. Subordination..........................  A Series of Securities may consist of one or more classes of Senior
                                            Securities and one or more classes of Subordinated Securities. The
                                            rights of the holders of the Subordinated Securities of a Series to
                                            receive distributions with respect to the assets in the related Trust
                                            Fund will be subordinated to such rights of the holders of the Senior
                                            Securities of the same Series to the extent described in the related
                                            Prospectus Supplement. This subordination is intended to enhance the
                                            likelihood of regular receipt by holders of Senior Securities of the
                                            full amount of monthly payments of principal and interest due them.
                                            The protection afforded to the holders of Senior Securities of a
                                            Series by means of the subordination feature will be accomplished by
                                            (i) the preferential right of such holders to receive, prior to any
                                            distribution being made in respect of the related Subordinated
                                            Securities, the amounts of interest and/or principal due them on each
                                            Distribution Date out of the funds available for distribution on such
                                            date in the related Security Account and, to the extent described in
                                            the related Prospectus Supplement, by the right of such holders to
                                            receive future distributions on the assets in the related Trust Fund
                                            that would otherwise have been payable to the holders of Subordinated
                                            Securities; (ii) reducing the ownership interest (if applicable) of
                                            the related Subordinated Securities; or (iii) a combination of
                                            clauses (i) and (ii) above. If so specified in the related Prospectus
                                            Supplement, subordination may apply only in the event of certain
                                            types of losses not covered by other forms of credit support, such as
                                            hazard losses not covered by standard hazard insurance policies or
                                            losses due to the bankruptcy or fraud of the borrower. The related
                                            Prospectus Supplement will set forth information concerning, among
                                            other things, the amount of subordination of a class or classes of
                                            Subordinated Securities in a Series, the circumstances in which such
                                            subordination will be applicable, and the manner, if any, in which
                                            the amount of subordination will decrease over time.
B. Reserve Account........................  One or more reserve accounts or other cash accounts (each, a 'Reserve
                                            Account') may be established and maintained for each Series of
                                            Securities. The related Prospectus Supplement will specify whether or
                                            not such Reserve Accounts will be included in the corpus of the Trust
                                            Fund for such Series and will also specify the manner of funding such
                                            Reserve Accounts and the conditions under which the amounts in any
                                            such Reserve Accounts will be used to make distributions to holders
                                            of Securities of a particular class or released from such Reserve
                                            Accounts.
C. Letter of Credit.......................  If so specified in the related Prospectus Supplement, credit support
                                            may be provided by one or more letters of credit. A letter of credit
                                            may provide limited protection against certain losses in addition to
                                            or in lieu of other credit support, such as losses resulting from
                                            delinquent payments on the Loans in the related Trust Fund, losses
                                            from risks not covered by standard hazard insurance policies, losses
                                            due to bankruptcy of a borrower and application of certain provisions
                                            of the federal Bankruptcy Code, and losses due to denial of insurance
                                            coverage due to misrepresentations made in connection with the
                                            origination or sale of a Loan. The issuer of the letter of credit
                                            (the 'L/C Bank') will be obligated to honor demands with

                                            available thereunder to provide funds under the circumstances and
                                            subject to such conditions as are specified in the related Prospectus
                                            Supplement. The liability of the L/C Bank under its letter of credit
                                            will be reduced by the amount of unreimbursed payments thereunder.
                                            The maximum liability of a L/C Bank under its letter of credit will
                                            be an amount equal to a percentage specified in the related
                                            Prospectus Supplement of the initial aggregate outstanding principal
                                            balance of the Loans in the related Trust Fund or one or more Classes
                                            of Securities of the related Series (the 'L/C Percentage'). The
                                            maximum amount available at any time to be paid under a letter of
                                            credit will be determined in the manner specified therein and in the
                                            related Prospectus Supplement.
D. Insurance Policies; Surety Bonds and

                                            for a Series may be provided by an insurance policy and/or a surety
                                            bond issued by one or more insurance companies or sureties. Such
                                            certificate guarantee insurance or surety bond will guarantee timely
                                            distributions of interest and/or full distributions of principal on
                                            the basis of a schedule of principal distributions set forth in or
                                            determined in the manner specified in the related Prospectus
                                            Supplement. If specified in the related Prospectus Supplement, one or
                                            more bankruptcy bonds, special hazard insurance policies, other
                                            insurance or third-party guarantees may be used to provide coverage
                                            for the risks of default or types of losses set forth in such
                                            Prospectus Supplement.
E. Over-Collateralization.................  If so provided in the Prospectus Supplement for a Series of
                                            Securities, a portion of the interest payment on each Loan may be
                                            applied as an additional distribution in respect of principal to
                                            reduce the principal balance of a certain class or classes of
                                            Securities and, thus, accelerate the rate of payment of principal on
                                            such class or classes of Securities.
F. Loan Pool Insurance Policy.............  A mortgage pool insurance policy or policies may be obtained and
                                            maintained for Loans relating to any Series of Securities, which
                                            shall be limited in scope, covering defaults on the related Loans in
                                            an initial amount equal to a specified percentage of the aggregate
                                            principal balance of all Loans included in the Pool as of the related
                                            Cut-off Date.
G. FHA Insurance..........................  If specified in the related Prospectus Supplement, all or a portion
                                            of the Loans in a Pool may be (i) insured by the Federal Housing
                                            Administration (the 'FHA') and/or (ii) partially guaranteed by the
                                            Department of Veterans' Affairs (the 'VA'). See 'Certain Legal
                                            Aspects of the Loans -- The Title I Program'.
H. Cross-Collateralization................  If specified in the related Prospectus Supplement, separate classes
                                            of a Series of Securities may evidence the beneficial ownership of,
                                            or be secured by, separate groups of assets included in a Trust Fund.
                                            In such case, credit support may be provided by a cross-
                                            collateralization feature which requires that distributions be made
                                            with respect to Securities evidencing a beneficial ownership interest
                                            in, or secured by, one or more asset groups prior to distributions to

                                            If specified in the related Prospectus Supplement, the coverage
                                            provided by one or more of the forms of credit enchancement described
                                            in this Prospectus may apply concurrently to two or more separate
                                            Trust Funds. If applicable, the related Prospectus Supplement will
                                            identify the Trust Funds to which such credit enchancement relates
                                            and the manner of determining the amount of coverage provided to such
                                            Trust Funds thereby and of the application of such coverage to the
                                            identified Trust Funds. See 'Credit
                                            Enhancement -- Cross-Collateralization.'
Advances..................................  The Master Servicer and, if applicable, each mortgage servicing
                                            institution that services a Loan in a Pool on behalf of the Master
                                            Servicer (each, a 'Sub-Servicer') may be obligated to advance amounts
                                            (each, an 'Advance') corresponding to delinquent interest and/or
                                            principal payments on such Loan (including, in the case of
                                            Cooperative Loans, unpaid maintenance fees or other charges under the
                                            related proprietary lease) until the date, as specified in the
                                            related Prospectus Supplement, following the date on which the
                                            related Property is sold at a foreclosure sale or the related Loan is
                                            otherwise liquidated. Any obligation to make Advances may be subject
                                            to limitations as specified in the related Prospectus Supplement. If
                                            so specified in the related Prospectus Supplement, Advances may be
                                            drawn from a cash account available for such purpose as described in
                                            such Prospectus Supplement. Advances will be reimbursable to the
                                            extent described under 'Description of the Securities -- Advances'
                                            herein and in the related Prospectus Supplement.
                                            In the event the Master Servicer or Sub-Servicer fails to make a
                                            required Advance, the Trustee may be obligated to advance such
                                            amounts otherwise required to be advanced by the Master Servicer or
                                            Sub-Servicer. See 'Description of the Securities -- Advances.'
Optional Termination......................  The Master Servicer or the party specified in the related Prospectus
                                            Supplement, including the holder of the residual interest in a REMIC,
                                            may have the option to effect early retirement of a Series of
                                            Securities through the purchase of the Trust Fund Assets. The Master
                                            Servicer will deposit the proceeds of any such purchase in the
                                            Security Account for each Trust Fund as described under 'The
                                            Agreements -- Payments on Loans; Deposit to Security Account.' Any
                                            such purchase of Trust Fund Assets and property acquired in respect
                                            of Trust Fund Assets evidenced by a Series of Securities will be made
                                            at the option of the Master Servicer, such other person or, if
                                            applicable, such holder of the REMIC residual interest, at a price
                                            specified in the related Prospectus Supplement. The exercise of such
                                            right will effect early retirement of the Securities of that Series,
                                            but the right of the Master Servicer, such other person or, if
                                            applicable, such holder of the REMIC residual interest, to so
                                            purchase is subject to the principal balance of the related Trust
                                            Fund Assets being less than the percentage specified in the related
                                            Prospectus Supplement of the aggregate principal balance of the

                                            Trust Fund Assets at the Cut-off Date for the Series. The foregoing
                                            is subject to the provision that if a REMIC election is made with
                                            respect to a Trust Fund, any repurchase pursuant to clause (ii) above
                                            will be made only in connection with a 'qualified liquidation' of the
                                            REMIC within the meaning of Section 860F(g)(4) of the Code.
Legal Investment..........................  The Prospectus Supplement for each series of Securities will specify
                                            which, if any, of the classes of Securities offered thereby
                                            constitute 'mortgage related securities' for purposes of the
                                            Secondary Mortgage Market Enhancement Act of 1984 ('SMMEA'). Classes
                                            of Securities that qualify as 'mortgage related securities' will be
                                            legal investments for certain types of institutional investors to the
                                            extent provided in SMMEA, subject, in any case, to any other
                                            regulations which may govern investments by such institutional
                                            investors. Institutions whose investment activities are subject to
                                            review by federal or state authorities should consult with their
                                            counsel or the applicable authorities to determine whether an
                                            investment in a particular class of Securities (whether or not such
                                            class constitutes a 'mortgage related security') complies with
                                            applicable guidelines, policy statements or restrictions. See 'Legal
                                            Investment.'
Federal Income Tax Consequences...........  The federal income tax consequences to Securityholders will vary
                                            depending on whether one or more elections are made to treat the
                                            Trust Fund or specified portions thereof as a REMIC under the
                                            provisions of the Internal Revenue Code of 1986, as amended (the
                                            'Code'). The Prospectus Supplement for each Series of Securities will
                                            specify whether such an election will be made.
                                            If a REMIC election is made, Securities representing regular
                                            interests in a REMIC will generally be taxable to holders in the same
                                            manner as evidences of indebtedness issued by the REMIC. Stated
                                            interest on such regular interests will be taxable as ordinary income
                                            and taken into account using the accrual method of accounting,
                                            regardless of the holder's normal accounting method. If no REMIC
                                            election is made, interest (other than original issue discount
                                            ('OID') on Securities that are characterized as indebtedness for
                                            federal income tax purposes will be includible in income by holders
                                            thereof in accordance with their usual method of accounting.
                                            Certain Classes of Securities may be issued with OID. A holder should
                                            be aware that the Code and the Treasury regulations promulgated
                                            thereunder do not adequately address certain issues relevant to
                                            prepayable securities, such as the Securities.
                                            Holders that will be required to report income with respect to the
                                            related Securities under the accrual method of accounting will do so
                                            without giving effect to delays and reductions in distributions
                                            attributable to a default or delinquency on the Loans, except
                                            possibly to the extent that it can be established that such amounts
                                            are uncollectible. As a result, the amount of income (including OID)
                                            reported by a holder of a Security in any period could significantly
                                            exceed the amount of cash distributed to such holder in that period.

                                            In the opinion of Brown & Wood LLP, if a REMIC election is made with
                                            respect to a Series of Securities, then the arrangement by which such
                                            Securities are issued will be treated as a REMIC as long as all of
                                            the provisions of the applicable Agreement are complied with and the
                                            statutory and regulatory requirements are satisfied. Securities will
                                            be designated as 'regular interests' or 'residual interests' in a
                                            REMIC. A REMIC will not be subject to entity-level tax. Rather, the
                                            taxable income or net loss of a REMIC will be taken into account by
                                            the holders of residual interests. Such holders will report their
                                            proportionate share of the taxable income of the REMIC whether or not
                                            they receive cash distributions from the REMIC attributable to such
                                            income. The portion of the REMIC taxable income consisting of 'excess
                                            inclusions' may not be offset against other deductions or losses of
                                            the holder, including the net operating losses.
                                            In the opinion of Brown & Wood LLP, if a REMIC or a partnership
                                            election is not made with respect to a Series of Securities, then the
                                            arrangement by which such Securities are issued will be classified as
                                            a grantor trust under Subpart E, Part I of Subchapter J of the Code
                                            and not as an association taxable as a corporation. If so provided in
                                            the Prospectus Supplement for a Series, there will be no separation
                                            of the principal and interest payments on the Loans. In such
                                            circumstances, the holder will considered to have purchased a pro
                                            rata undivided interest in each of the Loans. In other cases, sale of
                                            the Securities will produce a separation in the ownership of all or a
                                            portion of the principal payments from all or a portion of the
                                            interest payments on the Loans.
                                            In the opinion of Brown & Wood LLP, if a partnership election is
                                            made, the Trust Fund will not be treated as an association or a
                                            publicly traded partnership taxable as a corporation as long as all
                                            of the provisions of the applicable Agreement are complied with and
                                            the statutory and regulatory requirements are satisfied. If Notes are
                                            issued by such Trust Fund, such Notes will be treated as indebtedness
                                            for federal income tax purposes. The holders of the Certificates
                                            issued by such Trust Fund, if any, will agree to treat the
                                            Certificates as equity interests in a partnership.
                                            The Securities will be treated as assets described in section
                                            7701(a)(19)(C) of the Code and as real estate assets described in
                                            section 856(c) of the Code.
                                            Generally, gain or loss will be recognized on a sale of Securities in
                                            the amount equal to the difference between the amount realized and
                                            the seller's tax basis in the Securities sold.
                                            The material federal income tax consequences for investors associated
                                            with the purchase, ownership and disposition of the Securities are
                                            set forth herein under 'Federal Income -- Tax Consequences'. The
                                            material federal income tax consequences for investors associated
                                            with the purchase, ownership and disposition of Securities of any
                                            particular Series will be set forth under the heading 'Federal Income

                                            1974, as amended ('ERISA'), or the Code should carefully review with
                                            its legal advisors whether the purchase or holding of Securities
                                            could give rise to a transaction prohibited or not otherwise
                                            permissible under ERISA or the Code. See 'ERISA Considerations'.
                                            Certain classes of Securities may not be transferred unless the
                                            Trustee and the Depositor are furnished with a letter of

                                            transfer will not result in a violation of the prohibited transaction
                                            provisions of ERISA and the Code and will not subject the Trustee,

<PAGE>
<PAGE>

                                  RISK FACTORS
 
     Investors should consider the following factors in connection with the
purchase of the Securities.
 
LIMITED LIQUIDITY
 
     There will be no market for the Securities of any Series prior to the
issuance thereof, and there can be no assurance that a secondary market will
develop or, if it does develop, that it will provide Securityholders with
liquidity of investment or will continue for the life of the Securities of such
Series.
 
LIMITED SOURCE OF PAYMENTS -- NO RECOURSE TO SELLERS, DEPOSITOR OR MASTER
SERVICER
 
     The Depositor does not have, nor is it expected to have, any significant
assets. Unless otherwise specified in the related Prospectus Supplement, the
Securities of a Series will be payable solely from the Trust Fund for such
Securities and will not have any claim against or security interest in the Trust
Fund for any other Series. There will be no recourse to the Depositor or any
other person for any failure to receive distributions on the Securities.
Further, at the times set forth in the related Prospectus Supplement, certain
Trust Fund Assets and/or any balance remaining in the Security Account
immediately after making all payments due on the Securities of such Series,
after making adequate provision for future payments on certain classes of
Securities and after making any other payments specified in the related
Prospectus Supplement, may be promptly released or remitted to the Depositor,
the Master Servicer, any credit enhancement provider or any other person
entitled thereto and will no longer be available for making payments to
Securityholders. Consequently, holders of Securities of each Series must rely
solely upon payments with respect to the Trust Fund Assets and the other assets
constituting the Trust Fund for a Series of Securities, including, if
applicable, any amounts available pursuant to any credit enhancement for such
Series, for the payment of principal of and interest on the Securities of such
Series.
 
     The Securities will not represent an interest in or obligation of the
Depositor, the Master Servicer, any Seller or any of their respective
affiliates. The only obligations, if any, of the Depositor with respect to the
Trust Fund Assets or the Securities of any Series will be pursuant to certain
representations and warranties. The Depositor does not have, and is not expected
in the future to have, any significant assets with which to meet any obligation
to repurchase Trust Fund Assets with respect to which there has been a breach of
any representation or warranty. If, for example, the Depositor were required to
repurchase a Loan, its only sources of funds to make such repurchase would be
from funds obtained (i) from the enforcement of a corresponding obligation, if
any, on the part of the related Seller or originator of such Loan, or (ii) to
the extent provided in the related Prospectus Supplement, from a Reserve Account
or similar credit enhancement established to provide funds for such repurchases.
 
     The only obligations of the Master Servicer, other than its master
servicing obligations, with respect to the Trust Fund Assets or the Securities
of any Series will be pursuant to certain representations and warranties. The
Master Servicer may be required to repurchase or substitute for any Loan with
respect to which such representations and warranties are breached. There is no
assurance, however, that the Master Servicer will have the financial ability to
effect any such repurchase or substitution.
 
     The only obligations of any Seller with respect to Trust Fund Assets or the
Securities of any Series will be pursuant to certain representations and
warranties and certain document delivery requirements. A Seller may be required
to repurchase or substitute for any Loan with respect to which such
representations and warranties or document delivery requirements are breached.
There is no assurance, however, that such Seller will have the financial ability
to effect such repurchase or substitution.
 
CREDIT ENHANCEMENT
 
     Although credit enhancement is intended to reduce the risk of delinquent
payments or losses to holders of Securities entitled to the benefit thereof, the
amount of such credit enhancement will be limited, as set forth in the related
Prospectus Supplement, and may be subject to periodic reduction in accordance
with a schedule or formula or otherwise decline, and could be depleted under
certain circumstances prior to the payment in full of the related Series of
Securities, and as a result Securityholders of the related Series may suffer
losses. Moreover, such credit enhancement may not cover all potential losses or
risks. For example, credit enhancement may or may not cover fraud or negligence
by a loan originator or other parties. In addition, the Trustee will generally
be
 
                                       14
 

<PAGE>
<PAGE>

permitted to reduce, terminate or substitute all or a portion of the credit
enhancement for any Series of Securities, provided the applicable Rating Agency
indicates that the then-current rating of the Securities of such Series will not
be adversely affected. See 'Credit Enhancement'.
 
PREPAYMENT AND YIELD CONSIDERATIONS
 
     The timing of principal payments of the Securities of a Series will be
affected by a number of factors, including the following: (i) the extent of
prepayments (including for this purpose prepayments resulting from refinancing
or liquidations of the Loans due to defaults, casualties, condemnations and
repurchases by the Depositor or the Master Servicer) of the Loans comprising the
Trust Fund, which prepayments may be influenced by a variety of factors
including general economic conditions, prevailing interest rate levels, the
availability of alternative financing and homeowner mobility, (ii) the manner of
allocating principal and/or payments among the classes of Securities of a Series
as specified in the related Prospectus Supplement, (iii) the exercise by the
party entitled thereto of any right of optional termination and (iv) the rate
and timing of payment defaults and losses incurred with respect to the Trust
Fund Assets. The repurchase of Loans by the Depositor or the Master Servicer may
result from repurchases of Trust Fund Assets due to material breaches of the
Depositor's or the Master Servicer's representations and warranties, as
applicable. The yields to maturity and weighted average lives of the Securities
will be affected primarily by the rate and timing of prepayment of the Loans
comprising the Trust Fund Assets. In addition, the yields to maturity and
weighted average lives of the Securities will be affected by the distribution of
amounts remaining in any Pre-Funding Account following the end of the related
Funding Period. Any reinvestment risks resulting from a faster or slower
incidence of prepayment of Loans held by a Trust Fund will be borne entirely by
the holders of one or more classes of the related Series of Securities. See
'Yield and Prepayment Considerations' and 'The Agreements -- Pre-Funding
Account.'
 
     Interest payable on the Securities of a Series on a Distribution Date will
include all interest accrued during the period specified in the related
Prospectus Supplement. In the event interest accrues over a period ending two or
more days prior to a Distribution Date, the effective yield to Securityholders
will be reduced from the yield that would otherwise be obtainable if interest
payable on the Securities were to accrue through the day immediately preceding
each Distribution Date, and the effective yield (at par) to Securityholders will
be less than the indicated coupon rate. See 'Description of the
Securities -- Distributions on Securities -- Distributions of Interest'.
 
BALLOON PAYMENTS
 
     Certain of the Loans as of the related Cut-off Date may not be fully
amortizing over their terms to maturity and, thus, will require substantial
principal payments (i.e., balloon payments) at their stated maturity. Loans with
balloon payments involve a greater degree of risk because the ability of a
borrower to make a balloon payment typically will depend upon its ability either
to timely refinance the loan or to timely sell the related Property. The ability
of a borrower to accomplish either of these goals will be affected by a number
of factors, including the level of available mortgage rates at the time of sale
or refinancing, the borrower's equity in the related Property, the financial
condition of the borrower and tax laws. Losses on such Loans that are not
otherwise covered by the credit enhancement described in the applicable
Prospectus Supplement will be borne by the holders of one or more classes of
Securities of the related Series.
 
NATURE OF MORTGAGES
 
     Property Values.  There are several factors that could adversely affect the
value of Properties such that the outstanding balance of the related Loans,
together with any senior financing on the Properties, if applicable, would equal
or exceed the value of the Properties. Among the factors that could adversely
affect the value of the Properties are an overall decline in the residential
real estate market in the areas in which the Properties are located or a decline
in the general condition of the Properties as a result of failure of borrowers
to maintain adequately the Properties or of natural disasters that are not
necessarily covered by insurance, such as earthquakes and floods. In the case of
Home Equity Loans, such decline could extinguish the value of the interest of a
junior mortgagee in the Property before having any effect on the interest of the
related senior mortgagee. If such a decline occurs, the actual rates of
delinquencies, foreclosures and losses on all Loans could
 
                                       15
 

<PAGE>
<PAGE>

be higher than those currently experienced in the mortgage lending industry in
general. Losses on such Loans that are not otherwise covered by the credit
enhancement described in the applicable Prospectus Supplement will be borne by
the holder of one or more classes of Securities of the related Series.
 
     Delays Due to Liquidation.  Even assuming that the Properties provide
adequate security for the Loans, substantial delays could be encountered in
connection with the liquidation of defaulted Loans and corresponding delays in
the receipt of related proceeds by Securityholders could occur. An action to
foreclose on a Property securing a Loan is regulated by state statutes and rules
and is subject to many of the delays and expenses of other lawsuits if defenses
or counterclaims are interposed, sometimes requiring several years to complete.
Furthermore, in some states an action to obtain a deficiency judgment is not
permitted following a nonjudicial sale of a Property. In the event of a default
by a borrower, these restrictions, among other things, may impede the ability of
the Master Servicer to foreclose on or sell the Property or to obtain
liquidation proceeds sufficient to repay all amounts due on the related Loan. In
addition, the Master Servicer will be entitled to deduct from related
liquidation proceeds all expenses reasonably incurred in attempting to recover
amounts due on defaulted Loans and not yet repaid, including payments to senior
lienholders, legal fees and costs of legal action, real estate taxes and
maintenance and preservation expenses.
 
     Disproportionate Effect of Liquidation Expenses.  Liquidation expenses with
respect to defaulted loans generally do not vary directly with the outstanding
principal balance of the loan at the time of default. Therefore, assuming that a
servicer took the same steps in realizing upon a defaulted loan having a small
remaining principal balance as it would in the case of a defaulted loan having a
large remaining principal balance, the amount realized after expenses of
liquidation would be smaller as a percentage of the outstanding principal
balance of the small loan than would be the case with the defaulted loan having
a large remaining principal balance.
 
     Home Equity Loans; Junior Liens.  Since the mortgages and deeds of trust
securing the Home Equity Loans will be primarily junior liens subordinate to the
rights of the mortgagee under the related senior mortgage(s) or deed(s) of
trust, the proceeds from any liquidation, insurance or condemnation proceeds
will be available to satisfy the outstanding balance of such junior lien only to
the extent that the claims of such senior mortgagees have been satisfied in
full, including any related foreclosure costs. In addition, if a junior
mortgagee forecloses on the property securing a junior mortgage, it forecloses
subject to any senior mortgage and must either pay the entire amount due on any
senior mortgage to the related senior mortgagee at or prior to the foreclosure
sale or undertake the obligation to make payments on any such senior mortgage in
the event the mortgagor is in default thereunder in order to protect the junior
mortgagee's interest in the property. The Trust Fund will not have any source of
funds to satisfy any senior mortgages or make payments due to any senior
mortgagees and may therefore effectively be prevented from foreclosing on the
related property.
 
     Certain states have imposed statutory and judicial restrictions that limit
the remedies of a secured lender in the event that the proceeds of any sale
under a deed of trust or other foreclosure proceedings are insufficient to pay
amounts owed to such secured lender. In certain states, including California, if
a lender simultaneously originates a loan secured by a senior lien on a
particular property and a loan secured by a junior lien on the same property,
such a lender as the holder of the junior lien may be precluded from obtaining a
deficiency judgment with respect to the excess of the aggregate amount owed
under both such loans over the proceeds of any sale under a deed of trust or
other foreclosure proceedings. See 'Certain Legal Aspects of the Loans --
Anti-Deficiency Legislation; Bankruptcy Laws; Tax Liens.'
 
     Consumer Protection Laws.  Applicable state laws generally regulate
interest rates and other charges, require certain disclosures, and require
licensing of certain originators and servicers of Loans. In addition, most
states have other laws, public policy and general principles of equity relating
to the protection of consumers, unfair and deceptive practices and practices
which may apply to the origination, servicing and collection of the Loans.
Depending on the provisions of the applicable law and the specific facts and
circumstances involved, violations of these laws, policies and principles may
limit the ability of the Master Servicer to collect all or part of the principal
of or interest on the Loans, may entitle the borrower to a refund of amounts
previously paid and, in addition, could subject the Master Servicer to damages
and administrative sanctions. See 'Certain Legal Aspects of the Loans'.

MULTIFAMILY LOANS
 
     Multifamily lending may be viewed as exposing the lender to a greater risk
of loss than single family residential lending. Owners of multifamily
residential properties rely on monthly lease payments from tenants to pay for
maintenance and other operating expenses of such properties, to fund capital
improvements and to service any mortgage loan and any other debt that may be
secured by such properties. Various factors, many of which are beyond the
control of the owner or operator of such a property, may affect the economic
viability of that property.
 
     Changes in payment patterns by tenants may result from a variety of social,
legal and economic factors. Economic factors including the rate of inflation,
unemployment levels and relative rates offered for various types of housing may
be reflected in changes in payment patterns including increased risks of
defaults by tenants and higher vacancy rates. Adverse economic conditions,
either local or national, may limit the amount of rent that can be charged and
may result in a reduction in timely lease payments or a reduction in occupancy
levels. Occupancy and rent levels may also be affected by construction of
additional housing units, competition and local politics, including rent
stabilization or rent control laws and policies. In addition, the level of
mortgage interest rates may encourage tenants to purchase single family housing.
The Depositor is unable to determine and has no basis to predict whether, or to
what extent, economic, legal or social factors will affect future rental or
payment patterns.
 
     The location and construction quality of a particular building may affect
the occupancy level as well as the rents that may be charged for individual
units. The characteristics of a neighborhood may change over time or in relation
to newer developments. The effects of poor construction quality will increase
over time in the form of increased maintenance and capital improvements. Even
good construction will deteriorate over time if adequate maintenance is not
performed in a timely fashion.
 
UNSECURED HOME IMPROVEMENT AND OTHER LOANS
 
     The Trust Fund for any Series may include Home Improvement Loans that are
not secured by an interest in real estate or otherwise. The Trust Fund for any
Series may also include Home Equity Loans that were originated with
Loan-to-Value Ratios or Combined Loan-to-Value Ratios in excess of the value of
the related Mortgaged Property pledged as security therefor. Under such
circumstances, the Trust Fund for the related Series could be treated as a
general unsecured creditor as to any unsecured portion of any such Loan. In the
event of a default under a Loan that is unsecured in whole or in part, the
related Trust Fund will have recourse only against the borrower's assets
generally for the unsecured portion of the Loan, along with all other general
unsecured creditors of the borrower. In a bankruptcy or insolvency proceeding
relating to a borrower on any such Loan, the unsecured obligations of the
borrower with respect to such Loan may be discharged, even though the value of
the borrower's assets made available to the related Trust Fund as a general
unsecured creditor is insufficient to pay amounts due and owing under the
related Loan.
 
ENVIRONMENTAL RISKS
 
     Real property pledged as security to a lender may be subject to certain
environmental risks. Under the laws of certain states, contamination of a
property may give rise to a lien on the property to assure the costs of cleanup.
In several states, such a lien has priority over the lien of an existing
mortgage against such property. In addition under the laws of some states and
under the federal Comprehensive Environmental Response, Compensation and
Liability Act of 1980 ('CERCLA'), a lender may be liable, as an 'owner' or
'operator', for costs of addressing releases or threatened releases of hazardous
substances that require remedy at a property, if agents or employees of the
lender have become sufficiently involved in the operations of the borrower,
regardless of whether the environmental damage or threat was caused by a prior
owner. Such costs could result in a loss to the holders of one or more classes
of Securities of the related Series. A lender also risks such liability on
foreclosure of the related property. See 'Certain Legal Aspects of the
Loans -- Environmental Risks'.
 
CERTAIN OTHER LEGAL ASPECTS OF THE LOANS
 
     Consumer Protection Laws.  The Loans may also be subject to federal laws,
including:
 
          (i) the Federal Truth in Lending Act and Regulation Z promulgated
     thereunder, which require certain disclosures to the borrowers regarding
     the terms of the Loans;
 
                                       17
 

<PAGE>
<PAGE>

          (ii) the Equal Credit Opportunity Act and Regulation B promulgated
     thereunder, which prohibit discrimination on the basis of age, race, color,
     sex, religion, marital status, national origin, receipt of public
     assistance or the exercise of any right under the Consumer Credit
     Protection Act, in the extension of credit;
 
          (iii) the Fair Credit Reporting Act, which regulates the use and
     reporting of information related to the borrower's credit experience; and
 
          (iv) for Loans that were originated or closed after November 7, 1989,
     the Home Equity Loan Consumer Protection Act of 1988, which requires
     additional application disclosures, limits changes that may be made to the
     loan documents without the borrower's consent and restricts a lender's
     ability to declare a default or to suspend or reduce a borrower's credit
     limit to certain enumerated events.
 
     The Riegle Act.  Certain mortgage loans may be subject to the Riegle
Community Development and Regulatory Improvement Act of 1994 (the 'Riegle Act')
which incorporates the Home Ownership and Equity Protection Act of 1994. These
provisions impose additional disclosure and other requirements on creditors with
respect to non-purchase money mortgage loans with high interest rates or high
up-front fees and charges. The provisions of the Riegle Act apply on a mandatory
basis to all mortgage loans originated on or after October 1, 1995. These
provisions can impose specific statutory liabilities upon creditors who fail to
comply with their provisions and may affect the enforceability of the related
loans. In addition, any assignee of the creditor would generally be subject to
all claims and defenses that the consumer could assert against the creditor,
including, without limitation, the right to rescind the mortgage loan.
 
     Holder in Due Course Rules.  The Home Improvement Contracts are also
subject to the Preservation of Consumers' Claims and Defenses regulations of the
Federal Trade Commission and other similar federal and state statutes and
regulations (collectively, the 'Holder in Due Course Rules'), which protect the
homeowner from defective craftsmanship or incomplete work by a contractor. These
laws permit the obligor to withhold payment if the work does not meet the
quality and durability standards agreed to by the homeowner and the contractor.
The Holder in Due Course Rules have the effect of subjecting any assignee of the
seller in a consumer credit transaction to all claims and defenses which the
obligor in the credit sale transaction could assert against the seller of the
goods.
 
     Violations of certain provisions of these federal laws may limit the
ability of the Master Servicer to collect all or part of the principal of or
interest on the Loans and in addition could subject the Trust Fund to damages
and administrative enforcement. Losses on such Loans that are not otherwise
covered by the credit enhancement described in the applicable Prospectus
Supplement will be borne by the holders of one or more classes of Securities of
the related Series. See 'Certain Legal Aspects of the Loans'.
 
RATING OF THE SECURITIES
 
     It will be a condition to the issuance of a class of Securities offered
hereby that they be rated in one of the four highest rating categories by the
Rating Agency identified in the related Prospectus Supplement. Any such rating
would be based on, among other things, the adequacy of the value of the related
Trust Fund Assets and any credit enhancement with respect to such class and will
represent such Rating Agency's assessment solely of the likelihood that holders
of such class of Securities will receive payments to which such Securityholders
are entitled under the related Agreement. Such rating will not constitute an
assessment of the likelihood that principal prepayments on the related Loans
will be made, the degree to which the rate of such prepayments might differ from
that originally anticipated or the likelihood of early optional termination of
the Series of Securities. Such rating shall not be deemed a recommendation to
purchase, hold or sell Securities, inasmuch as it does not address market price
or suitability for a particular investor. Such rating will not address the
possibility that prepayment at higher or lower rates than anticipated by an
investor may cause such investor to experience a lower than anticipated yield or
that an investor purchasing a Security at a significant premium might fail to
recoup its initial investment under certain prepayment scenarios.
 
     There is also no assurance that any such rating will remain in effect for
any given period of time or that it may not be lowered or withdrawn entirely by
the Rating Agency in the future if in its judgment circumstances in the future
so warrant. In addition to being lowered or withdrawn due to any erosion in the
adequacy of the value of the Trust Fund Assets or any credit enhancement with
respect to a Series of Securities, such rating might also be lowered or
withdrawn because of, among other reasons, an adverse change in the financial or
other condition of a credit enhancement provider or a change in the rating of
such credit enhancement provider's long term debt.

     The amount, type and nature of credit enhancement, if any, established with
respect to a class of Securities will be determined on the basis of criteria
established by each Rating Agency rating classes of such Series. Such criteria
are sometimes based upon an actuarial analysis of the behavior of similar loans
in a larger group. Such analysis is often the basis upon which each Rating
Agency determines the amount of credit enhancement required with respect to each
such class. There can be no assurance that the historical data supporting any
such actuarial analysis will accurately reflect future experience nor any
assurance that the data derived from a large pool of similar loans accurately
predicts the delinquency, foreclosure or loss experience of any particular pool
of Loans. No assurance can be given that the values of any Properties have
remained or will remain at their levels on the respective dates of origination
of the related Loans. If the residential real estate markets should experience
an overall decline in property values such that the outstanding principal
balances of the Loans in a particular Trust Fund and any secondary financing on
the related Properties become equal to or greater than the value of the
Properties, the rates of delinquencies, foreclosures and losses could be higher
than those now generally experienced in the mortgage lending industry. In
addition, adverse economic conditions (which may or may not affect real property
values) may affect the timely payment by mortgagors of scheduled payments of
principal and interest on the Loans and, accordingly, the rates of
delinquencies, foreclosures and losses with respect to any Trust Fund. To the
extent that such losses are not covered by credit enhancement, such losses will
be borne, at least in part, by the holders of one or more classes of Securities
of the related Series. See 'Rating'.
 
BOOK-ENTRY REGISTRATION
 
     If issued in book-entry form, such registration may reduce the liquidity of
the Securities in the secondary trading market since investors may be unwilling
to purchase Securities for which they cannot obtain physical certificates. Since
transactions in book-entry Securities can be effected only through the
Depository Trust Company ('DTC'), participating organizations, Financial
Intermediaries and certain banks, the ability of a Securityholder to pledge a
book-entry Security to persons or entities that do not participate in the DTC
system may be limited due to lack of a physical certificate representing such
Securities. Securities Owners will not be recognized as Securityholders as such
term is used in the related Agreement, and Security Owners will be permitted to
exercise the rights of Securityholders only indirectly through DTC and its
Participants.
 
     In addition, Securityholders may experience some delay in their receipt of
distributions of interest and principal on book-entry Securities since
distributions are required to be forwarded by the Trustee to DTC and DTC will
then be required to credit such distributions to the accounts of Depository
participants which thereafter will be required to credit them to the accounts of
Securityholders either directly or indirectly through Financial Intermediaries.
See 'Description of the Securities -- Book-Entry Registration of Securities'.
 
PRE-FUNDING ACCOUNTS
 
     If so provided in the related Prospectus Supplement, on the related Closing
Date the Depositor will deposit cash in an amount (the 'Pre-Funded Amount')
specified in such Prospectus Supplement into an account (the 'Pre-Funding
Account'). In no event shall the Pre-Funded Amount exceed 50% of the initial
aggregate principal amount of the Certificates and/or Notes of the related
Series of Securities. The Pre-Funded Amount will be used to purchase Loans
('Subsequent Loans') in a period from the related Closing Date to a date not
more than one year after such Closing Date (such period, the 'Funding Period')
from the Depositor (which, in turn, will acquire such Subsequent Loans from the
Seller or Sellers specified in the related Prospectus Supplement). The
Pre-Funding Account will be maintained with the Trustee for the related Series
of Securities and is designed solely to hold funds to be applied by such Trustee
during the Funding Period to pay to the Depositor the purchase price for
Subsequent Loans. Monies on deposit in the Pre-Funding Account will not be
available to cover losses on or in respect of the related Loans. To the extent
that the entire Pre-Funded Amount has not been applied to the purchase of
Subsequent Loans by the end of the related Funding Period, any amounts remaining
in the Pre-Funding Account will be distributed as a prepayment of principal to
Certificateholders and/or Noteholders on the Distribution Date immediately
following the end of the Funding Period, in the amounts and pursuant to the
priorities set forth in the related Prospectus Supplement. Any reinvestment risk
resulting from such prepayment will be borne entirely by the holders of one or
more classes of the related Series of Certificates.
 
BANKRUPTCY AND INSOLVENCY RISKS
 
     The Seller and the Depositor will treat the transfer of the Loans by the
Seller to the Depositor as a sale for accounting purposes. The Depositor and the
Trust Fund will treat the transfer of Loans from the Depositor to the
 
                                       19
 

<PAGE>
<PAGE>

Trust Fund as a sale for accounting purposes. As a sale of the Loans by the
Seller to the Depositor, the Loans would not be part of the Seller's bankruptcy
estate and would not be available to the Seller's creditors. However, in the
event of the insolvency of the Seller, it is possible that the bankruptcy
trustee or a creditor of the Seller may attempt to recharacterize the sale of
the Loans as a borrowing by the Seller, secured by a pledge of the Loans.
Similarly, as a sale of the Loans by the Depositor to the Trust Fund, the Loans
would not be part of the Depositor's bankruptcy estate and would not be
available to the Depositor's creditors. However, in the event of the insolvency
of the Depositor, it is possible that the bankruptcy trustee or a creditor of
the Depositor may attempt to recharacterize the sale of the Loans as a borrowing
by the Depositor, secured by a pledge of the Loans. In either case, this
position, if argued before or accepted by a court, could prevent timely payments
of amounts due on the Securities and result in a reduction of payments due on
the Securities.
 
     In the event of a bankruptcy or insolvency of the Master Servicer, the
bankruptcy trustee or receiver may have the power to prevent the Trustee or the
Securityholders from appointing a successor Servicer. The time period during
which cash collections may be commingled with the Master Servicer's own funds
prior to each Distribution Date will be specified in the related Prospectus
Supplement. In the event of the insolvency of the Master Servicer and if such
cash collections are commingled with the Master Servicer's own funds for at
least ten days, the Trust Fund will likely not have a perfected interest in such
collections since such collections would not have been deposited in a segregated
account within ten days after the collection thereof, and the inclusion thereof
in the bankruptcy estate of the Master Servicer may result in delays in payment
and failure to pay amounts due on the Securities of the related Series.
 
     In addition, federal and state statutory provisions, including the federal
bankruptcy laws and state laws affording relief to debtors, may interfere with
or affect the ability of the secured mortgage lender to realize upon its
security. For example, in a proceeding under the federal Bankruptcy Code, a
lender may not foreclose on a mortgaged property without the permission of the
bankruptcy court. The rehabilitation plan proposed by the debtor may provide, if
the mortgaged property is not the debtor's principal residence and the court
determines that the value of the mortgaged property is less than the principal
balance of the mortgage loan, for the reduction of the secured indebtedness to
the value of the mortgaged property as of the date of the commencement of the
bankruptcy, rendering the lender a general unsecured creditor for the
difference, and also may reduce the monthly payments due under such mortgage
loan, change the rate of interest and alter the mortgage loan repayment
schedule. The effect of any such proceedings under the federal Bankruptcy Code,
including but not limited to any automatic stay, could result in delays in
receiving payments on the Loans underlying a Series of Securities and possible
reductions in the aggregate amount of such payments.
 
CONSEQUENCES OF OWNING ORIGINAL ISSUE DISCOUNT SECURITIES.
 
     Debt Securities that are Compound Interest Securities will be, and certain
of the other Debt Securities may be, issued with original discount for federal
income tax purposes. A holder of Debt Securities issued with original issue
discount will be required to include original issue discount in ordinary gross
income for federal income tax purposes as it accrues, in advance of receipt of
the cash attributable to such income. Accrued but unpaid interest on the Debt
Securities that are Compound Interest Securities generally will be treated as
original issue discount for this purpose. See 'Federal Income Tax
Consequences -- Taxation of Debt Securities -- Interest and Acquisition
Discount' and ' -- Market Discount' herein.
 
VALUE OF TRUST FUND ASSETS
 
     There is no assurance that the market value of the Trust Fund Assets or any
other assets relating to a Series of Securities described under 'Credit
Enhancement' herein will at any time be equal to or greater than the principal
amount of the Securities of such Series then outstanding, plus accrued interest
thereon. Moreover, upon an event of default under the Agreement for a Series of
Securities and a sale of the related Trust Fund Assets or upon a sale of the
assets of a Trust Fund for a Series of Securities, the Trustee, the Master
Servicer, the credit enhancer, if any, and any other service provider specified
in the related Prospectus Supplement generally will be entitled to receive the
proceeds of any such sale to the extent of unpaid fees and other amounts owing
to such persons under the related Agreement prior to distributions to
Securityholders. Upon any such sale, the proceeds thereof may be insufficient to
pay in full the principal of and interest on the Securities of such Series.

                                 THE TRUST FUND
 
GENERAL
 
     The Securities of each Series will represent interests in the assets of the
related Trust Fund, and the Notes of each Series will be secured by the pledge
of the assets of the related Trust Fund. The Trust Fund for each Series will be
held by the Trustee for the benefit of the related Securityholders. Each Trust
Fund will consist of certain assets (the 'Trust Fund Assets') consisting of a
pool (each, a 'Pool') comprised of Loans as specified in the related Prospectus
Supplement, together with payments in respect of such Loans, as specified in the
related Prospectus Supplement.* The Pool will be created on the first day of the
month of the issuance of the related Series of Securities or such other date
specified in the related Prospectus Supplement (the 'Cut-off Date'). The
Securities will be entitled to payment from the assets of the related Trust Fund
or Funds or other assets pledged for the benefit of the Securityholders, as
specified in the related Prospectus Supplement and will not be entitled to
payments in respect of the assets of any other trust fund established by the
Depositor.
 
     The Trust Fund Assets will be acquired by the Depositor, either directly or
through affiliates, from originators or sellers which may be affiliates of the
Depositor (the 'Sellers'), and conveyed without recourse by the Depositor to the
related Trust Fund. Loans acquired by the Depositor will have been originated in
accordance with the underwriting criteria specified below under 'Loan
Program -- Underwriting Standards' or as otherwise described in the related
Prospectus Supplement. See 'Loan Program -- Underwriting Standards'.
 
     The Depositor will cause the Trust Fund Assets to be assigned to the
Trustee named in the related Prospectus Supplement for the benefit of the
holders of the Securities of the related Series. The Master Servicer named in
the related Prospectus Supplement will service the Trust Fund Assets, either
directly or through other servicing institutions ('Sub-Servicers'), pursuant to
a Pooling and Servicing Agreement among the Depositor, the Master Servicer and
the Trustee with respect to a Series consisting of Certificates, or a master
servicing agreement (each, a 'Master Servicing Agreement') between the Trustee
and the Master Servicer with respect to a Series consisting of Certificates and
Notes, and will receive a fee for such services. See 'Loan Program' and 'The
Agreements'. With respect to Loans serviced by the Master Servicer through a
Sub-Servicer, the Master Servicer will remain liable for its servicing
obligations under the related Agreement as if the Master Servicer alone were
servicing such Loans.
 
     As used herein, 'Agreement' means, with respect to a Series consisting of
Certificates, the Pooling and Servicing Agreement, and with respect to a Series
consisting of Certificates and Notes, the Trust Agreement, the Indenture and the
Master Servicing Agreement, as the context requires.
 
     If so specified in the related Prospectus Supplement, a Trust Fund relating
to a Series of Securities may be a business trust formed under the laws of the
state specified in the related Prospectus Supplement pursuant to a trust
agreement (each, a 'Trust Agreement') between the Depositor and the trustee of
such Trust Fund.
 
     With respect to each Trust Fund, prior to the initial offering of the
related Series of Securities, the Trust Fund will have no assets or liabilities.
No Trust Fund is expected to engage in any activities other than acquiring,
managing and holding of the related Trust Fund Assets and other assets
contemplated herein specified and in the related Prospectus Supplement and the
proceeds thereof, issuing Securities and making payments and distributions
thereon and certain related activities. No Trust Fund is expected to have any
source of capital other than its assets and any related credit enhancement.
 
     Unless otherwise specified in the related Prospectus Supplement, the only
obligations of the Depositor with respect to a Series of Securities will be to
obtain certain representations and warranties from the Sellers and to assign to
the Trustee for such Series of Securities the Depositor's rights with respect to
such representations and warranties. See 'The Agreements -- Assignment of the
Trust Fund Assets'. The obligations of the Master
 
- ------------------------------
* Whenever the terms 'Pool', 'Certificates', 'Notes' and 'Securities' are used
  in this Prospectus, such terms will be deemed to apply, unless the context
  indicates otherwise, to one specific Pool and the Securities of one Series
  including the Certificates representing certain undivided interests in, and/or
  Notes secured by the assets of, a single Trust Fund consisting primarily of
  the Loans in such Pool. Similarly, the term 'Pass-Through Rate' will refer to
  the Pass-Through Rate borne by the Certificates and the term 'interest rate'
  will refer to the interest rate borne by the Notes of one specific Series, as
  applicable, and the term 'Trust Fund' will refer to one specific Trust Fund.
 
                                       21

Servicer with respect to the Loans will consist principally of its contractual
servicing obligations under the related Agreement (including its obligation to
enforce the obligations of the Sub-Servicers or Sellers, or both, as more fully
described herein under 'Loan Program -- Representations by Sellers; Repurchases'
and 'The Agreements -- Sub-Servicing By Sellers' and ' -- Assignment of the
Trust Fund Assets') and its obligation, if any, to make certain cash advances in
the event of delinquencies in payments on or with respect to the Loans in the
amounts described herein under 'Description of the Securities -- Advances'. The
obligations of the Master Servicer to make advances may be subject to
limitations, to the extent provided herein and in the related Prospectus
Supplement.
 
     The following is a brief description of the assets expected to be included
in the Trust Funds. If specific information respecting the Trust Fund Assets is
not known at the time the related Series of Securities initially is offered,
more general information of the nature described below will be provided in the
related Prospectus Supplement, and specific information will be set forth in a
report on Form 8-K to be filed with the Securities and Exchange Commission
within fifteen days after the initial issuance of such Securities (the 'Detailed
Description'). A copy of the Agreement with respect to each Series of Securities
will be attached to the Form 8-K and will be available for inspection at the
corporate trust office of the Trustee specified in the related Prospectus
Supplement. A schedule of the Loans relating to such Series will be attached to
the Agreement delivered to the Trustee upon delivery of the Securities.
 
THE LOANS
 
     General.  Loans will consist of Single Family Loans, Multifamily Loans,
Home Equity Loans or Home Improvement Contracts. For purposes hereof, 'Home
Equity Loans' includes 'Closed-End Loans' and 'Revolving Credit Line Loans'. If
so specified, the Loans may include cooperative apartment loans ('Cooperative
Loans') secured by security interests in shares issued by private, non-profit,
cooperative housing corporations ('Cooperatives') and in the related proprietary
leases or occupancy agreements granting exclusive rights to occupy specific
dwelling units in such Cooperatives' buildings. As more fully described in the
related Prospectus Supplement, the Loans may be 'conventional' loans or loans
that are insured or guaranteed by a governmental agency such as the FHA or VA.
 
     Unless otherwise specified in the related Prospectus Supplement, all of the
Loans in a Pool will have monthly payments due on the first or fifteenth day of
each month. The payment terms of the Loans to be included in a Trust Fund will
be described in the related Prospectus Supplement and may include any of the
following features (or combination thereof), all as described below or in the
related Prospectus Supplement:
 
          (a) Interest may be payable at a fixed rate, a rate adjustable from
     time to time in relation to an index (which will be specified in the
     related Prospectus Supplement), a rate that is fixed for a period of time
     or under certain circumstances and is followed by an adjustable rate, a
     rate that otherwise varies from time to time, or a rate that is convertible
     from an adjustable rate to a fixed rate. Changes to an adjustable rate may
     be subject to periodic limitations, maximum rates, minimum rates or a
     combination of such limitations. Accrued interest may be deferred and added
     to the principal of a Loan for such periods and under such circumstances as
     may be specified in the related Prospectus Supplement. Loans may provide
     for the payment of interest at a rate lower than the specified interest
     rate borne by such Loan (the 'Loan Rate') for a period of time or for the
     life of the Loan, and the amount of any difference may be contributed from
     funds supplied by the seller of the Property or another source.
 
          (b) Principal may be payable on a level debt service basis to fully
     amortize the Loan over its term, may be calculated on the basis of an
     assumed amortization schedule that is significantly longer than the
     original term to maturity or on an interest rate that is different from the
     Loan Rate or may not be amortized during all or a portion of the original
     term. Payment of all or a substantial portion of the principal may be due
     on maturity ('balloon payment'). Principal may include interest that has
     been deferred and added to the principal balance of the Loan.
 
          (c) Monthly payments of principal and interest may be fixed for the
     life of the Loan, may increase over a specified period of time or may
     change from period to period. Loans may include limits on periodic
     increases or decreases in the amount of monthly payments and may include
     maximum or minimum amounts of monthly payments.
 
                                       22
 

<PAGE>
<PAGE>

          (d) Prepayments of principal may be subject to a prepayment fee, which
     may be fixed for the life of the Loan or may decline over time, and may be
     prohibited for the life of the Loan or for certain periods ('lockout
     periods'). Certain Loans may permit prepayments after expiration of the
     applicable lockout period and may require the payment of a prepayment fee
     in connection with any such subsequent prepayment. Other Loans may permit
     prepayments without payment of a fee unless the prepayment occurs during
     specified time periods. The Loans may include 'due on sale' clauses which
     permit the mortgagee to demand payment of the entire Loan in connection
     with the sale or certain transfers of the related Property. Other Loans may
     be assumable by persons meeting the then applicable underwriting standards
     of the related Seller.
 
     A Trust Fund may contain certain Loans ('Buydown Loans') that include
provisions whereby a third party partially subsidizes the monthly payments of
the borrowers on such Loans during the early years of such Loans, the difference
to be made up from a fund (a 'Buydown Fund') contributed by such third party at
the time of origination of the Loan. A Buydown Fund will be in an amount equal
either to the discounted value or full aggregate amount of future payment
subsidies. The underlying assumption of buydown plans is that the income of the
borrower will increase during the buydown period as a result of normal increases
in compensation and inflation, so that the borrower will be able to meet the
full loan payments at the end of the buydown period. To the extent that this
assumption as to increased income is not fulfilled, the possibility of defaults
on Buydown Loans is increased. The related Prospectus Supplement will contain
information with respect to any Buydown Loan concerning limitations on the
interest rate paid by the borrower initially, on annual increases in the
interest rate and on the length of the buydown period.
 
     The real property which secures repayment of the Loans is referred to as
the 'Mortgaged Properties'. Home Improvement Contracts may, and the other Loans
will, be secured by mortgages or deeds of trust or other similar security
instruments creating a lien on a Mortgaged Property. In the case of Home Equity
Loans, such liens generally will be subordinated to one or more senior liens on
the related Mortgaged Properties as described in the related Prospectus
Supplement. As specified in the related Prospectus Supplement, Home Improvement
Contracts may be unsecured or secured by purchase money security interests in
the Home Improvements financed thereby. If so specified in the related
Prospectus Supplement, the Home Equity Loans may include Loans (primarily for
home improvement or debt consolidation purposes) that are in amounts in excess
of the value of the related Mortgaged Properties at the time of origination. The
Mortgaged Properties and the Home Improvements are collectively referred to
herein as the 'Properties'. The Properties may be located in any one of the
fifty states, the District of Columbia, Guam, Puerto Rico or any other territory
of the United States.
 
     Loans with certain Loan-to-Value Ratios and/or certain principal balances
may be covered wholly or partially by primary mortgage guaranty insurance
policies (each, a 'Primary Mortgage Insurance Policy'). The existence, extent
and duration of any such coverage will be described in the applicable Prospectus
Supplement.
 
     The aggregate principal balance of Loans secured by Properties that are
owner-occupied will be disclosed in the related Prospectus Supplement. Unless
otherwise specified in the related Prospectus Supplement, the sole basis for a
representation that a given percentage of the Loans is secured by Single Family
Properties that are owner-occupied will be either (i) the making of a
representation by the borrower at origination of the Loan either that the
underlying Property will be used by the borrower for a period of at least six
months every year or that the borrower intends to use the Property as a primary
residence or (ii) a finding that the address of the underlying Property is the
borrower's mailing address.
 
     Single Family Loans.  The Mortgaged Properties relating to Single Family
Loans will consist of detached or semi-detached one- to four-family dwelling
units, townhouses, rowhouses, individual condominium units, individual units in
planned unit developments, manufactured housing that is permanently affixed and
treated as real property under local law, and certain other dwelling units
('Single Family Properties'). Single Family Properties may include vacation and
second homes, investment properties and leasehold interests. In the case of
leasehold interests, the term of the leasehold will exceed the scheduled
maturity of the Loan by at least five years, unless otherwise specified in the
related Prospectus Supplement.
 
     Multifamily Loans.  Mortgaged Properties which secure Multifamily Loans may
include small multifamily residential properties such as rental apartment
buildings or projects containing five to fifty residential units, including
mid-rise and garden apartments. Certain of the Multifamily Loans may be secured
by apartment buildings owned by Cooperatives. In such cases, the Cooperative
owns all the apartment units in the building and all common areas. The
Cooperative is owned by tenant-stockholders who, through ownership of stock,
 
                                       23
 

<PAGE>
<PAGE>

shares or membership certificates in the corporation, receive proprietary leases
or occupancy agreements which confer exclusive rights to occupy specific
apartments or units. Generally, a tenant-stockholder of a Cooperative must make
a monthly payment to the Cooperative representing such tenant-stockholder's pro
rata share of the Cooperative's payments for its mortgage loan, real property
taxes, maintenance expenses and other capital or ordinary expenses. Those
payments are in addition to any payments of principal and interest the tenant-
stockholder must make on any loans to the tenant-stockholder secured by its
shares in the Cooperative. The Cooperative will be directly responsible for
building management and, in most cases, payment of real estate taxes and hazard
and liability insurance. A Cooperative's ability to meet debt service
obligations on a Multifamily Loan, as well as all other operating expenses, will
be dependent in large part on the receipt of maintenance payments from the
tenant-stockholders, as well as any rental income from units the Cooperative
might control. Unanticipated expenditures may in some cases have to be paid by
special assessments on the tenant-stockholders.
 
     Home Equity Loans.  The Mortgaged Properties relating to Home Equity Loans
will consist of Single Family Properties. As more fully described in the related
Prospectus Supplement, interest on each Revolving Credit Line Loan, excluding
introductory rates offered from time to time during promotional periods, is
computed and payable monthly on the average daily outstanding principal balance
of such Loan. Principal amounts on a Revolving Credit Line Loan may be drawn
down (up to a maximum amount as set forth in the related Prospectus Supplement)
or repaid under each Revolving Credit Line Loan from time to time, but may be
subject to a minimum periodic payment. Except to the extent provided in the
related Prospectus Supplement, the Trust Fund will not include any amounts
borrowed under a Revolving Credit Line Loan after the Cut-off Date. The full
amount of a Closed-End Loan is advanced at the inception of the Loan and
generally is repayable in equal (or substantially equal) installments of an
amount to fully amortize such Loan at its stated maturity. Except to the extent
provided in the related Prospectus Supplement, the original terms to stated
maturity of Closed-End Loans will not exceed 360 months. Under certain
circumstances, under either a Revolving Credit Line Loan or a Closed-End Loan, a
borrower may choose an interest only payment option and is obligated to pay only
the amount of interest which accrues on the Loan during the billing cycle. An
interest only payment option may be available for a specified period before the
borrower must begin paying at least the minimum monthly payment of a specified
percentage of the average outstanding balance of the Loan.
 
     Home Improvement Contracts.  The Trust Fund Assets for a Series of
Securities may consist, in whole or in part, of Home Improvement Contracts
originated by a home improvement contractor, a thrift or a commercial mortgage
banker in the ordinary course of business. The Home Improvements securing the
Home Improvement Contracts may include, but are not limited to, replacement
windows, house siding, new roofs, swimming pools, satellite dishes, kitchen and
bathroom remodeling goods and solar heating panels. As specified in the related
Prospectus Supplement, the Home Improvement Contracts will either be unsecured
or secured by mortgages on Single Family Properties which are generally
subordinate to other mortgages on the same Property, or secured by purchase
money security interests in the Home Improvements financed thereby. Except as
otherwise specified in the related Prospectus Supplement, the Home Improvement
Contracts will be fully amortizing and may have fixed interest rates or
adjustable interest rates and may provide for other payment characteristics as
described below and in the related Prospectus Supplement. The initial
Loan-to-Value Ratio of a Home Improvement Contract is computed in the manner
described in the related Prospectus Supplement.
 
     Additional Information.  Each Prospectus Supplement will contain
information, as of the date of such Prospectus Supplement and to the extent then
specifically known to the Depositor, with respect to the Loans contained in the
related Pool, including (i) the aggregate outstanding principal balance and the
average outstanding principal balance of the Loans as of the applicable Cut-off
Date, (ii) the type of property securing the Loan (e.g., single family
residences, individual units in condominium apartment buildings, small multi-
family properties, other real property or Home Improvements), (iii) the original
terms to maturity of the Loans, (iv) the largest principal balance and the
smallest principal balance of any of the Loans, (v) the earliest origination
date and latest maturity date of any of the Loans, (vi) the Loan-to-Value Ratios
or Combined Loan-to-Value Ratios, as applicable, of the Loans, (vii) the Loan
Rates or annual percentage rates ('APR') or range of Loan Rates or APR's borne
by the Loans, (viii) the maximum and minimum per annum Loan Rates, and (ix) the
geographical location of the Loans. If specific information respecting the Loans
is not known to the Depositor at the time the related Securities are initially
offered, more general information of the nature described above will be provided
in the related Prospectus Supplement, and specific information will be set forth
in the Detailed Description.

     The 'Loan-to-Value Ratio' of a Loan at any given time is the fraction,
expressed as a percentage, the numerator of which is the original principal
balance of the related Loan and the denominator of which is the Collateral Value
of the related Property. The 'Combined Loan-to-Value Ratio' of a Loan at any
given time is the ratio, expressed as a percentage, of (i) the sum of (a) the
original principal balance of the Loan (or, in the case of a Revolving Credit
Line Loan, the maximum amount thereof available) and (b) the outstanding
principal balance at the date of origination of the Loan of any senior mortgage
loan(s) or, in the case of any open-ended senior mortgage loan, the maximum
available line of credit with respect to such mortgage loan, regardless of any
lesser amount actually outstanding at the date of origination of the Loan, to
(ii) the Collateral Value of the related Property. The 'Collateral Value' of the
Property, other than with respect to certain Loans the proceeds of which were
used to refinance an existing mortgage loan (each, a 'Refinance Loan'), is the
lesser of (a) the appraised value determined in an appraisal obtained by the
originator at origination of such Loan and (b) the sales price for such
Property. In the case of Refinance Loans, the 'Collateral Value' of the related
Property is generally the appraised value thereof determined in an appraisal
obtained at the time of refinancing.
 
     No assurance can be given that values of the Properties have remained or
will remain at their levels on the dates of origination of the related Loans. If
the residential real estate market should experience an overall decline in
property values such that the sum of the outstanding principal balances of the
Loans and any primary or secondary financing on the Properties, as applicable,
in a particular Pool become equal to or greater than the value of the
Properties, the actual rates of delinquencies, foreclosures and losses could be
higher than those now generally experienced in the mortgage lending industry. In
addition, adverse economic conditions and other factors (which may or may not
affect real property values) may affect the timely payment by borrowers of
scheduled payments of principal and interest on the Loans and, accordingly, the
actual rates of delinquencies, foreclosures and losses with respect to any Pool.
To the extent that such losses are not covered by subordination provisions or
alternative arrangements, such losses will be borne, at least in part, by the
holders of the Securities of the related Series.
 
SUBSTITUTION OF TRUST FUND ASSETS
 
     Substitution of Trust Fund Assets will be permitted in the event of
breaches of representations and warranties with respect to any original Trust
Fund Asset or in the event the documentation with respect to any Trust Fund
Asset is determined by the Trustee to be incomplete. The period during which
such substitution will be permitted generally will be indicated in the related
Prospectus Supplement.
 
                                USE OF PROCEEDS
 
     The net proceeds to be received from the sale of the Securities will be
applied by the Depositor to the purchase of Trust Fund Assets or will be used by
the Depositor for general corporate purposes. The Depositor expects to sell
Securities in Series from time to time, but the timing and amount of offerings
of Securities will depend on a number of factors, including the volume of Trust
Fund Assets acquired by the Depositor, prevailing interest rates, availability
of funds and general market conditions.
 
                                 THE DEPOSITOR
 
     CWABS, Inc., a Delaware corporation (the 'Depositor'), was incorporated in
August 1996 for the limited purpose of acquiring, owning and transferring Trust
Fund Assets and selling interests therein or bonds secured thereby. The
Depositor is a limited purpose finance subsidiary of Countrywide Credit
Industries, Inc., a Delaware corporation. The Depositor maintains its principal
office at 4500 Park Granada, Calabasas, California 91302. Its telephone number
is (818) 225-3000.
 
     Neither the Depositor nor any of the Depositor's affiliates will insure or
guarantee distributions on the Securities of any Series.
 
                                  LOAN PROGRAM
 
     The Loans will have been purchased by the Depositor, either directly or
through affiliates, from Sellers. Unless otherwise specified in the related
Prospectus Supplement, the Loans so acquired by the Depositor will have been
originated in accordance with the underwriting criteria specified below under
'Underwriting Standards'.
 
                                       25
 

<PAGE>
<PAGE>

UNDERWRITING STANDARDS
 
     Unless otherwise specified in the related Prospectus Supplement, each
Seller will represent and warrant that all Loans originated and/or sold by it to
the Depositor or one of its affiliates 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 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 related Property as collateral. In general, a prospective borrower
applying for a Loan is required to fill out a detailed application designed to
provide to the underwriting officer pertinent credit information, including the
principal balance and payment history with respect to any senior mortgage, if
any, which, unless otherwise specified in the related Prospectus Supplement,
will be verified by the related Seller. As part of the description of the
borrower's financial condition, the borrower generally is required to provide
a current list of assets and liabilities and a statement of income and expenses,
as well as an authorization to apply for a credit report which summarizes the
borrower's credit history with local merchants and lenders and any record of
bankruptcy. In most cases, an employment verification is obtained from an
independent source (typically the borrower's employer) which verification
reports, among other things, the length of employment with that organization
and the borrower's current salary. If a prospective borrower is self-employed,
the borrower may be required to submit copies of signed tax returns. The
borrower may also be required to authorize verification of deposits at financial
institutions where the borrower has demand or savings accounts.
 
     In determining the adequacy of the property to be used as collateral, an
appraisal will generally be made of each property considered for financing. The
appraiser is generally required to inspect the property, issue a report on its
condition and, if applicable, verify construction, if new, has been completed.
The appraisal is generally based on the market value of comparable homes, the
estimated rental income (if considered applicable by the appraiser) and the cost
of replacing the home. The value of the property being financed, as indicated by
the appraisal, must be such that it currently supports, and is anticipated to
support in the future, the outstanding loan balance.
 
     The maximum loan amount will vary depending upon a borrower's credit grade
and loan program but will not generally exceed $1,000,000. Variations in maximum
loan amount limits will be permitted based on compensating factors. Compensating
factors may generally include, to the extent specified in the related Prospectus
Supplement, low loan-to-value ratio, low debt-to-income ratio, stable
employment, favorable credit history and the nature of the underlying first
mortgage loan, if applicable.
 
     Each Seller's underwriting standards will generally permit loans with
loan-to-value ratios at origination of up to 100% depending on the loan program,
type and use of the property, creditworthiness of the borrower and
debt-to-income ratio. If so specified in the related Prospectus Supplement, a
Seller's underwriting criteria may permit loans with loan-to-value ratios at
origination in excess of 100%, such as for debt consolidation or home
improvement purposes. Loan-to-value ratios may not be evaluated in the case of
Title I Loans.
 
     After obtaining all applicable employment, credit and property information,
the related Seller will use a debt-to-income ratio to assist in determining
whether the prospective borrower has sufficient monthly income available to
support the payments of principal and interest on the mortgage loan in addition
to other monthly credit obligations. The 'debt-to-income ratio' is the ratio of
the borrower's total monthly payments to the borrower's gross monthly income.
The maximum monthly debt-to-income ratio will vary depending upon a borrower's
credit grade and loan program but will not generally exceed 55%. Variations in
the monthly debt-to-income ratio limit will be permitted based on compensating
factors to the extent specified in the related Prospectus Supplement.
 
     In the case of a Loan secured by a leasehold interest in real property, the
title to which is held by a third party lessor, the related Seller will, unless
otherwise specified in the related Prospectus Supplement, represent and warrant,
among other things, that the remaining term of the lease and any sublease is at
least five years longer than the remaining term on the Loan.
 
     Certain of the types of Loans that may be included in a Trust Fund are
recently developed and may involve additional uncertainties not present in
traditional types of loans. For example, certain of such Loans may provide for
escalating or variable payments by the borrower. These types of Loans are
underwritten on the basis of a judgment that the borrowers have the ability to
make the monthly payments required initially. In some instances,
 
                                       26
 

<PAGE>
<PAGE>

a borrower's income may not be sufficient to permit continued loan payments as
such payments increase. These types of Loans may also be underwritten primarily
upon the basis of Loan-to-Value Ratios or other favorable credit factors.
 
QUALIFICATIONS OF SELLERS
 
     Each Seller will be required to satisfy the following qualifications. Each
Seller must be an institution experienced in originating and servicing loans of
the type contained in the related Pool in accordance with accepted practices and
prudent guidelines, and must maintain satisfactory facilities to originate and
service those loans. Each Seller must be a seller/servicer approved by either
the Federal National Mortgage Association ('FNMA') or the Federal Home Loan
Mortgage Corporation ('FHLMC'). Each Seller must be a mortgagee approved by the
FHA or an institution the deposit accounts of which are insured by the Federal
Deposit Insurance Corporation (the 'FDIC').
 
REPRESENTATIONS BY SELLERS; REPURCHASES
 
     Each Seller will have made representations and warranties in respect of the
Loans sold by such Seller and evidenced by all, or a part, of a Series of
Securities. Such representations and warranties may include, among other things:
(i) that title insurance (or in the case of Properties located in areas where
such policies are generally not available, an attorney's certificate of title)
and any required hazard insurance policy were effective at origination of each
Loan, other than Cooperative Loans and certain Home Equity Loans, and that each
policy (or certificate of title as applicable) remained in effect on the date of
purchase of the Loan from the Seller by or on behalf of the Depositor; (ii) that
the Seller had good title to each such Loan and such Loan was subject to no
offsets, defenses, counterclaims or rights of rescission except to the extent
that any buydown agreement may forgive certain indebtedness of a borrower; (iii)
that each Loan constituted a valid lien on, or a perfected security interest
with respect to, the Property (subject only to permissible liens disclosed, if
applicable, title insurance exceptions, if applicable, and certain other
exceptions described in the Agreement) and that the Property was free from
damage and was in acceptable condition; (iv) that there were no delinquent tax
or assessment liens against the Property; (v) that no required payment on a Loan
was delinquent more than the number of days specified in the related Prospectus
Supplement; and (vi) that each Loan was made in compliance with, and is
enforceable under, all applicable local, state and federal laws and regulations
in all material respects.
 
     If so specified in the related Prospectus Supplement, the representations
and warranties of a Seller in respect of a Loan will be made not as of the
Cut-off Date but as of the date on which such Seller sold the Loan to the
Depositor or one of its affiliates. Under such circumstances, a substantial
period of time may have elapsed between the sale date and the date of initial
issuance of the Series of Securities evidencing an interest in such Loan. Since
the representations and warranties of a Seller do not address events that may
occur following the sale of a Loan by such Seller, its repurchase obligation
described below will not arise if the relevant event that would otherwise have
given rise to such an obligation with respect to a Loan occurs after the date of
sale of such Loan by such Seller to the Depositor or its affiliates. However,
the Depositor will not include any Loan in the Trust Fund for any Series of
Securities if anything has come to the Depositor's attention that would cause it
to believe that the representations and warranties of a Seller will not be
accurate and complete in all material respects in respect of such Loan as of the
date of initial issuance of the related Series of Securities. If the Master
Servicer is also a Seller of Loans with respect to a particular Series of
Securities, such representations will be in addition to the representations and
warranties made by the Master Servicer in its capacity as a Master Servicer.
 
     The Master Servicer or the Trustee, if the Master Servicer is the Seller,
will promptly notify the relevant Seller of any breach of any representation or
warranty made by it in respect of a Loan which materially and adversely affects
the interests of the Securityholders in such Loan. Unless otherwise specified in
the related Prospectus Supplement, if such Seller cannot cure such breach within
90 days following notice from the Master Servicer or the Trustee, as the case
may be, then such Seller will be obligated either (i) to repurchase such Loan
from the Trust Fund at a price (the 'Purchase Price') equal to 100% of the
unpaid principal balance thereof as of the date of the repurchase plus accrued
interest thereon to the first day of the month following the month of repurchase
at the Loan Rate (less any Advances or amount payable as related servicing
compensation if the Seller is the Master Servicer) or (ii) substitute for such
Loan a replacement loan that satisfies the criteria specified in the related
Prospectus Supplement. If a REMIC election is to be made with respect to a Trust
Fund, unless otherwise specified in the related Prospectus Supplement, the
Master Servicer or a holder of the related residual certificate generally will
be obligated to pay any prohibited transaction tax which may arise in
 
                                       27
 

<PAGE>
<PAGE>

connection with any such repurchase or substitution and the Trustee must have
received a satisfactory opinion of counsel that such repurchase or substitution
will not cause the Trust Fund to lose its status as a REMIC or otherwise subject
the Trust Fund to a prohibited transaction tax. The Master Servicer may be
entitled to reimbursement for any such payment from the assets of the related
Trust Fund or from any holder of the related residual certificate. See
'Description of the Securities -- General'. Except in those cases in which the
Master Servicer is the Seller, the Master Servicer will be required under the
applicable Agreement to enforce this obligation for the benefit of the Trustee
and the holders of the Securities, following the practices it would employ in
its good faith business judgment were it the owner of such Loan. This repurchase
or substitution obligation will constitute the sole remedy available to holders
of Securities or the Trustee for a breach of representation by a Seller.
 
     Neither the Depositor nor the Master Servicer (unless the Master Servicer
is the Seller) will be obligated to purchase or substitute a Loan if a Seller
defaults on its obligation to do so, and no assurance can be given that Sellers
will carry out their respective repurchase or substitution obligations with
respect to Loans. However, to the extent that a breach of a representation and
warranty of a Seller may also constitute a breach of a representation made by
the Master Servicer, the Master Servicer may have a repurchase or substitution
obligation as described below under 'The Agreements -- Assignment of Trust Fund
Assets'.

                         DESCRIPTION OF THE SECURITIES
 
     Each Series of Certificates will be issued pursuant to separate agreements
(each, a 'Pooling and Servicing Agreement' or a 'Trust Agreement') among the
Depositor, the Master Servicer and the Trustee. A form of Pooling and Servicing
Agreement and Trust Agreement has been filed as an exhibit to the Registration
Statement of which this Prospectus forms a part. Each Series of Notes will be
issued pursuant to an indenture (the 'Indenture') between the related Trust Fund
and the entity named in the related Prospectus Supplement as trustee (the
'Trustee') with respect to such Series, and the related Loans will be serviced
by the Master Servicer pursuant to a Master Servicing Agreement. A form of
Indenture and Master Servicing Agreement has been filed as an exhibit to the
Registration Statement of which this Prospectus forms a part. A Series of
Securities may consist of both Notes and Certificates. Each Agreement, dated as
of the related Cut-off Date, will be among the Depositor, the Master Servicer
and the Trustee for the benefit of the holders of the Securities of such Series.
The provisions of each Agreement will vary depending upon the nature of the
Securities to be issued thereunder and the nature of the related Trust Fund. The
following are descriptions of the material provisions which may appear in each
Agreement. The descriptions are subject to, and are qualified in their entirety
by reference to, all of the provisions of the Agreement for each Series of
Securities and the applicable Prospectus Supplement. The Depositor will provide
a copy of the Agreement (without exhibits) relating to any Series without charge
upon written request of a holder of record of a Security of such Series
addressed to CWABS, Inc., 4500 Park Granada, Calabasas, California 91302,
Attention: Secretary.
 
GENERAL
 
     Unless otherwise specified in the related Prospectus Supplement, the
Securities of each Series will be issued in book-entry or fully registered form,
in the authorized denominations specified in the related Prospectus Supplement,
will, in the case of Certificates, evidence specified beneficial ownership
interests in, and in the case of Notes, be secured by, the assets of the related
Trust Fund created pursuant to each Agreement and will not be entitled to
payments in respect of the assets included in any other Trust Fund established
by the Depositor. Unless otherwise specified in the related Prospectus
Supplement, the Securities will not represent obligations of the Depositor or
any affiliate of the Depositor. Certain of the Loans may be guaranteed or
insured as set forth in the related Prospectus Supplement. Each Trust Fund will
consist of, to the extent provided in the related Agreement, (i) the Trust Fund
Assets, as from time to time are subject to the related Agreement (exclusive of
any amounts specified in the related Prospectus Supplement ('Retained
Interest')), including all payments of interest and principal received with
respect to the Loans after the Cut-off Date (to the extent not applied in
computing the principal balance of such Loans as of the Cut-off Date (the
'Cut-off Date Principal Balance')); (ii) such assets as from time to time are
required to be deposited in the related Security Account, as described below
under 'The Agreements -- Payments on Loans; Deposits to Security Account';
(iii) property which secured a Loan and which is acquired on behalf of the
Securityholders by foreclosure or deed in lieu of foreclosure and (iv) any
insurance policies or other forms of credit enhancement required to be
maintained pursuant to the related Agreement. If so specified in the related
Prospectus Supplement, a Trust Fund may also include one or more of the
following: reinvestment income on payments received on the Trust Fund Assets, a
Reserve Account, a mortgage pool insurance policy, a special hazard insurance
policy, a bankruptcy bond, one or more letters of credit, a surety bond,
guaranties or similar instruments.
 
     Each Series of Securities will be issued in one or more classes. Each class
of Certificates of a Series will evidence beneficial ownership of a specified
percentage (which may be 0%) or portion of future interest payments and a
specified percentage (which may be 0%) or portion of future principal payments
on, and each class of Notes of a Series will be secured by, the related Trust
Fund Assets. A Series of Securities may include one or more classes that are
senior in right to payment to one or more other classes of Securities of such
Series. Certain Series or classes of Securities may be covered by insurance
policies, surety bonds or other forms of credit enhancement, in each case as
described under 'Credit Enhancement' herein and in the related Prospectus
Supplement. One or more classes of Securities of a Series may be entitled to
receive distributions of principal, interest or any combination thereof.
Distributions on one or more classes of a Series of Securities may be made prior
to one or more other classes, after the occurrence of specified events, in
accordance with a schedule or formula or on the basis of collections from
designated portions of the related Trust Fund Assets, in each case as specified
in the related Prospectus Supplement. The timing and amounts of such
distributions may vary among classes or over time as specified in the related
Prospectus Supplement.
 
                                       29
 

<PAGE>
<PAGE>

     Distributions of principal and interest (or, where applicable, of principal
only or interest only) on the related Securities will be made by the Trustee on
each Distribution Date (i.e., monthly, quarterly, semi-annually or at such other
intervals and on the dates as are specified in the related Prospectus
Supplement) in proportion to the percentages specified in the related Prospectus
Supplement. Distributions will be made to the persons in whose names the
Securities are registered at the close of business on the dates specified in the
related Prospectus Supplement (each, a 'Record Date'). Distributions will be
made in the manner specified in the related Prospectus Supplement to the persons
entitled thereto at the address appearing in the register maintained for holders
of Securities (the 'Security Register'); provided, however, that the final
distribution in retirement of the Securities will be made only upon presentation
and surrender of the Securities at the office or agency of the Trustee or other
person specified in the notice to Securityholders of such final distribution.
 
     The Securities will be freely transferable and exchangeable at the
Corporate Trust Office of the Trustee as set forth in the related Prospectus
Supplement. No service charge will be made for any registration of exchange or
transfer of Securities of any Series, but the Trustee may require payment of a
sum sufficient to cover any related tax or other governmental charge.
 
     Under current law the purchase and holding of a class of Securities
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
Loans or a class of Securities entitled to receive payments of interest and
principal on the Loans only after payments to other classes or after the
occurrence of certain specified events by or on behalf of any employee benefit
plan or other retirement arrangement (including individual retirement accounts
and annuities, Keogh plans and collective investment funds in which such plans,
accounts or arrangements are invested) subject to provisions of ERISA or the
Code, may result in prohibited transactions, within the meaning of ERISA and the
Code. See 'ERISA Considerations'. Unless otherwise specified in the related
Prospectus Supplement, the transfer of Securities of such a class will not be
registered unless the transferee (i) represents that it is not, and is not
purchasing on behalf of, any such plan, account or arrangement or (ii) provides
an opinion of counsel satisfactory to the Trustee and the Depositor that the
purchase of Securities of such a class by or on behalf of such plan, account or
arrangement is permissible under applicable law and will not subject the
Trustee, the Master Servicer or the Depositor to any obligation or liability in
addition to those undertaken in the Agreements.
 
     As to each Series, an election may be made to treat the related Trust Fund
or designated portions thereof as a 'real estate mortgage investment conduit' or
'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 Master Servicer and may only be made if certain conditions are
satisfied. As to any such Series, the terms and provisions applicable to the
making of a REMIC election 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 Securities 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, the Master Servicer 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 provided in the related
Prospectus Supplement, will be entitled to reimbursement for any such payment
from the assets of the Trust Fund or from any holder of the related residual
certificate.
 
DISTRIBUTIONS ON SECURITIES
 
     General.  In general, the method of determining the amount of distributions
on a particular Series of Securities will depend on the type of credit support,
if any, that is used with respect to such Series. See 'Credit Enhancement'. Set
forth below are descriptions of various methods that may be used to determine
the amount of distributions on the Securities of a particular Series. The
Prospectus Supplement for each Series of Securities will describe the method to
be used in determining the amount of distributions on the Securities of such
Series.
 
     Distributions allocable to principal and interest on the Securities will be
made by the Trustee out of, and only to the extent of, funds in the related
Security Account, including any funds transferred from any Reserve Account (a
'Reserve Account'). As between Securities of different classes and as between
distributions of principal (and, if applicable, between distributions of
Principal Prepayments, as defined below, and scheduled payments of principal)
and interest, distributions made on any Distribution Date will be applied as
specified in
 
                                       30
 

<PAGE>
<PAGE>

the related Prospectus Supplement. The Prospectus Supplement will also describe
the method for allocating distributions among Securities of a particular class.
 
     Available Funds.  All distributions on the Securities of each Series on
each Distribution Date will be made from the Available Funds described below, in
accordance with the terms described in the related Prospectus Supplement and
specified in the Agreement. 'Available Funds' for each Distribution Date will
generally equal the amount on deposit in the related Security Account on such
Distribution Date (net of related fees and expenses payable by the related Trust
Fund) other than amounts to be held therein for distribution on future
Distribution Dates.
 
     Distributions of Interest.  Interest will accrue on the aggregate principal
balance of the Securities (or, in the case of Securities entitled only to
distributions allocable to interest, the aggregate notional amount) of each
class of Securities (the 'Class Security Balance') entitled to interest from the
date, at the Pass-Through Rate or interest rate, as applicable (which in either
case may be a fixed rate or rate adjustable as specified in such Prospectus
Supplement), and for the periods specified in such Prospectus Supplement. To the
extent funds are available therefor, interest accrued during each such specified
period on each class of Securities entitled to interest (other than a class of
Securities that provides for interest that accrues, but is not currently
payable, referred to hereafter as 'Accrual Securities') will be distributable on
the Distribution Dates specified in the related Prospectus Supplement until the
aggregate Class Security Balance of the Securities of such class has been
distributed in full or, in the case of Securities entitled only to distributions
allocable to interest, until the aggregate notional amount of such Securities is
reduced to zero or for the period of time designated in the related Prospectus
Supplement. The original Class Security Balance of each Security will equal the
aggregate distributions allocable to principal to which such Security is
entitled. Distributions allocable to interest on each Security that is not
entitled to distributions allocable to principal will be calculated based on the
notional amount of such Security. The notional amount of a Security will not
evidence an interest in or entitlement to distributions allocable to principal
but will be used solely for convenience in expressing the calculation of
interest and for certain other purposes.
 
     Interest payable on the Securities of a Series on a Distribution Date will
include all interest accrued during the period specified in the related
Prospectus Supplement. In the event interest accrues over a period ending two or
more days prior to a Distribution Date, the effective yield to Securityholders
will be reduced from the yield that would otherwise be obtainable if interest
payable on the Security were to accrue through the day immediately preceding
such Distribution Date, and the effective yield (at par) to Securityholders will
be less than the indicated coupon rate.
 
     With respect to any class of Accrual Securities, if specified in the
related Prospectus Supplement, any interest that has accrued but is not paid on
a given Distribution Date will be added to the aggregate Class Security Balance
of such class of Securities on that Distribution Date. Distributions of interest
on any class of Accrual Securities will commence only after the occurrence of
the events specified in such Prospectus Supplement. Prior to such time, the
beneficial ownership interest in the Trust Fund or the principal balance, as
applicable, of such class of Accrued Securities, as reflected in the aggregate
Class Security Balance of such class of Accrual Securities, will increase on
each Distribution Date by the amount of interest that accrued on such class of
Accrual Securities during the preceding interest accrual period but that was not
required to be distributed to such class on such Distribution Date. Any such
class of Accrual Securities will thereafter accrue interest on its outstanding
Class Security Balance as so adjusted.
 
     Distributions of Principal.  The related Prospectus Supplement will specify
the method by which the amount of principal to be distributed on the Securities
on each Distribution Date will be calculated and the manner in which such amount
will be allocated among the classes of Securities entitled to distributions of
principal. The aggregate Class Security Balance of any class of Securities
entitled to distributions of principal generally will be the aggregate original
Class Security Balance of such class of Securities specified in such Prospectus
Supplement, reduced by all distributions reported to the holders of such
Securities as allocable to principal and, (i) in the case of Accrual Securities,
unless otherwise specified in the related Prospectus Supplement, increased by
all interest accrued but not then distributable on such Accrual Securities and
(ii) in the case of adjustable rate Securities, subject to the effect of
negative amortization, if applicable.
 
     If so provided in the related Prospectus Supplement, one or more classes of
Securities will be entitled to receive all or a disproportionate percentage of
the payments of principal which are received from borrowers in advance of their
scheduled due dates and are not accompanied by amounts representing scheduled
interest due
 
                                       31
 

<PAGE>
<PAGE>

after the month of such payments ('Principal Prepayments') in the percentages
and under the circumstances or for the periods specified in such Prospectus
Supplement. Any such allocation of Principal Prepayments to such class or
classes of Securities will have the effect of accelerating the amortization of
such Securities while increasing the interests evidenced by one or more other
classes of Securities in the Trust Fund. Increasing the interests of the other
classes of Securities relative to that of certain Securities is intended to
preserve the availability of the subordination provided by such other
Securities. See 'Credit Enhancement -- Subordination'.
 
     Unscheduled Distributions.  If specified in the related Prospectus
Supplement, the Securities will be subject to receipt of distributions before
the next scheduled Distribution Date under the circumstances and in the manner
described below and in such Prospectus Supplement. If applicable, the Trustee
will be required to make such unscheduled distributions on the day and in the
amount specified in the related Prospectus Supplement if, due to substantial
payments of principal (including Principal Prepayments) on the Trust Fund
Assets, the Trustee or the Master Servicer determines that the funds available
or anticipated to be available from the Security Account and, if applicable, any
Reserve Account, may be insufficient to make required distributions on the
Securities on such Distribution Date. Unless otherwise specified in the related
Prospectus Supplement, the amount of any such unscheduled distribution that is
allocable to principal will not exceed the amount that would otherwise have been
required to be distributed as principal on the Securities on the next
Distribution Date. Unless otherwise specified in the related Prospectus
Supplement, the unscheduled distributions will include interest at the
applicable Pass-Through Rate (if any) or interest rate (if any) on the amount of
the unscheduled distribution allocable to principal for the period and to the
date specified in such Prospectus Supplement.
 
ADVANCES
 
     To the extent provided in the related Prospectus Supplement, the Master
Servicer will be required to advance on or before each Distribution Date (from
its own funds, funds advanced by Sub-Servicers or funds held in the Security
Account for future distributions to the holders of Securities of the related
Series), an amount equal to the aggregate of payments of interest and/or
principal that were delinquent on the related Determination Date (as such term
is defined in the related Prospectus Supplement) and were not advanced by any
Sub-Servicer, subject to the Master Servicer's determination that such advances
may be recoverable out of late payments by borrowers, Liquidation Proceeds,
Insurance Proceeds or otherwise. In the case of Cooperative Loans, the Master
Servicer also may be required to advance any unpaid maintenance fees and other
charges under the related proprietary leases as specified in the related
Prospectus Supplement.
 
     In making Advances, the Master Servicer will endeavor to maintain a regular
flow of scheduled interest and principal payments to holders of the Securities,
rather than to guarantee or insure against losses. If Advances are made by the
Master Servicer from cash being held for future distribution to Securityholders,
the Master Servicer will replace such funds on or before any future Distribution
Date to the extent that funds in the applicable Security Account on such
Distribution Date would be less than the amount required to be available for
distributions to Securityholders on such date. Any Master Servicer funds
advanced will be reimbursable to the Master Servicer out of recoveries on the
specific Loans with respect to which such Advances were made (e.g., late
payments made by the related borrower, any related Insurance Proceeds,
Liquidation Proceeds or proceeds of any Loan purchased by the Depositor, a
Sub-Servicer or a Seller pursuant to the related Agreement). Advances by the
Master Servicer (and any advances by a Sub-Servicer) also will be reimbursable
to the Master Servicer (or Sub-Servicer) from cash otherwise distributable to
Securityholders (including the holders of Senior Securities) to the extent that
the Master Servicer determines that any such Advances previously made are not
ultimately recoverable as described above. To the extent provided in the related
Prospectus Supplement, the Master Servicer also will be obligated to make
Advances, to the extent recoverable out of Insurance Proceeds, Liquidation
Proceeds or otherwise, in respect of certain taxes and insurance premiums not
paid by borrowers on a timely basis. Funds so advanced are reimbursable to the
Master Servicer to the extent permitted by the related Agreement. The
obligations of the Master Servicer to make advances may be supported by a cash
advance reserve fund, a surety bond or other arrangement of the type described
herein under 'Credit Enhancement', in each case as described in the related
Prospectus Supplement.
 
     Unless otherwise specified in the related Prospectus Supplement, in the
event the Master Servicer or a Sub-Servicer fails to make a required Advance,
the Trustee will be obligated to make such Advance in its capacity as successor
servicer. If the Trustee makes such an Advance, it will be entitled to be
reimbursed for such Advance

to the same extent and degree as the Master Servicer or a Sub-Servicer is
entitled to be reimbursed for Advances. See 'Description of the
Securities -- Distributions on Securities'.

                 Distribution Date;
            (x)  the book value of any real estate acquired through foreclosure or grant of a deed in lieu of
                 foreclosure;

amount per single Security of the relevant class having the Percentage Interest
specified in the related Prospectus Supplement. The report to Securityholders
for any Series of Securities may include additional or other information of a
similar nature to that specified above.
 
     In addition, within a reasonable period of time after the end of each
calendar year, the Master Servicer or the Trustee will mail to each
Securityholder of record at any time during such calendar year a report (a) as
to the aggregate of amounts reported pursuant to (i) and (ii) above for such
calendar year or, in the event such person was a Securityholder of record during
a portion of such calendar year, for the applicable portion of such year and (b)
such other customary information as may be deemed necessary or desirable for
Securityholders to prepare their tax returns.

CATEGORIES OF CLASSES OF SECURITIES
 
     The Securities of any Series may be comprised of one or more classes. Such
classes, in general, fall into different categories. The following chart
identifies and generally defines certain of the more typical categories. The
Prospectus Supplement for a series of Securities may identify the classes which
comprise such Series by reference to the following categories.
 
<TABLE>
<CAPTION>
CATEGORIES OF CLASSES                                              DEFINITION
                                                                 PRINCIPAL TYPES
<S>                             <C>
Accretion Directed............  A class that receives principal payments from the accreted interest from
                                specified Accrual classes. An Accretion Directed class also may receive principal
                                payments from principal paid on the underlying Trust Fund Assets for the related
                                Series.
Component Securities..........  A class consisting of 'Components.' The Components of a class of Component
                                Securities may have different principal and/or interest payment characteristics
                                but together constitute a single class. Each Component of a class of Component
                                Securities may be identified as falling into one or more of the categories in
                                this chart.
Notional Amount Securities....  A class having no principal balance and bearing interest on the related notional
                                amount. The notional amount is used for purposes of the determination of interest
                                distributions.
Planned Principal Class (also
  sometimes referred to as
  'PACs').....................  A class that is designed to receive principal payments using a predetermined
                                principal balance schedule derived by assuming two constant prepayment rates for
                                the underlying Trust Fund Assets. These two rates are the endpoints for the
                                'structuring range' for the Planned Principal Class. The Planned Principal
                                Classes in any Series of Securities may be subdivided into different categories
                                (e.g., Primary Planned Principal Classes, Secondary Planned Principal Classes and
                                so forth) having different effective structuring ranges and different principal
                                payment priorities. The structuring range for the Secondary Planned Principal
                                Categories of Classes Definition Class of a Series of Securities will be narrower
                                than that for the Primary Planned Principal Class of such Series.
Scheduled Principal Class.....  A class that is designed to receive principal payments using a predetermined
                                principal balance schedule but is not designated as a Planned Principal Class or
                                Targeted Principal class. In may cases, the schedule is derived by assuming two
                                constant prepayment rates for the underlying Trust Fund Assets. These two rates
                                are the endpoints for the 'structuring range' for the Scheduled Principal Class.
Sequential Pay................  Classes that receive principal payments in a prescribed sequence, that do not
                                have predetermined principal balance schedules and that under all circumstances
                                receive payments of principal continuously from the first Distribution Date on
                                which they receive principal until they are retired. A single class that receives
                                principal payments before or after all other classes in the same Series of
                                Securities may be identified as a Sequential Pay class.
Strip.........................  A class that receives a constant proportion, or 'strip,' of the principal
                                payments on the underlying Trust Fund Assets.
Support Class (also sometimes
  referred to as 'companion
  classes')...................  A class that receives principal payments on any Distribution Date only if
                                scheduled payments have been made on specified Planned Principal Classes,
                                Targeted Principal Classes and/or Scheduled Principal Classes.

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

<S>                             <C>
Fixed Rate....................  A class with an interest rate that is fixed throughout the life of the class.
Floating Rate.................  A class with an interest rate that resets periodically based upon a designated
                                index and that varies directly with changes in such index.
Inverse Floating Rate.........  A class with an interest rate that resets periodically based upon a designated
                                index and that varies inversely with changes in such index.
Variable Rate.................  A class with an interest rate that resets periodically and is calculated by
                                reference to the rate or rates of interest applicable to specified assets or
                                instruments (e.g., the Loan Rates borne by the underlying Loans).
Interest Only.................  A class that receives some or all of the interest payments made on the underlying
                                Trust Fund Assets and little or no principal. Interest Only classes have either a
                                nominal principal balance or a notional amount. A nominal principal balance
                                represents actual principal that will be paid on the class. It is referred to as
                                nominal since it is extremely small compared to other classes. A notional amount
                                is the amount used as a reference to calculate the amount of interest due on an
                                Interest Only class that is not entitled to any distributions in respect of
                                principal.
Principal Only................  A class that does not bear interest and is entitled to receive only distributions
                                in respect of principal.
Partial Accrual...............  A class that accretes a portion of the amount of accrued interest thereon, which
                                amount will be added to the principal balance of such class on each applicable
                                Distribution Date, with the remainder of such accrued interest to be distributed
                                currently as interest on such class. Such accretion may continue until a
                                specified event has occurred or until such Partial Accrual class is retired.
Accrual.......................  A class that accretes the amount of accrued interest otherwise distributable on
                                such class, which amount will be added as principal to the principal balance of
                                such class on each applicable Distribution Date. Such accretion may continue
                                until some specified event has occurred or until such Accrual class is retired.
</TABLE>
 
INDICES APPLICABLE TO FLOATING RATE AND INVERSE FLOATING RATE CLASSES
 
LIBOR
 
     Unless otherwise specified in the related Prospectus Supplement, on the
LIBOR Determination Date (as such term is defined in the related Prospectus
Supplement) for each class of Securities of a Series as to which the applicable
interest rate is determined by reference to an index denominated as LIBOR, the
Person designated in the related Agreement (the 'Calculation Agent') will
determine LIBOR by reference to the quotations, as set forth on the Reuters
Screen LIBO Page (as defined in the International Swap Dealers Association, Inc.
Code of Standard Wording, Assumptions and Provisions for Swaps, 1986 Edition),
offered by the principal London office of each of the designated reference banks
meeting the criteria set forth below (the 'Reference Banks') for making
one-month United States dollar deposits in leading banks in the London Interbank
market, as of 11:00 a.m. (London time) on such LIBOR Determination Date. In lieu
of relying on the quotations for those Reference Banks that appear at such time
on the Reuters Screen LIBO Page, the Calculation Agent will request each of the
Reference Banks to provide such offered quotations at such time.
 
     LIBOR will be established by the Calculation Agent on each LIBOR
Determination Date as follows:
 
                                       35
 

<PAGE>
<PAGE>

          (a) If on any LIBOR Determination Date two or more Reference Banks
     provide such offered quotations, LIBOR for the next Interest Accrual Period
     shall be the arithmetic mean of such offered quotations (rounded upwards if
     necessary to the nearest whole multiple of 1/32%).
 
          (b) If on any LIBOR Determination Date only one or none of the
     Reference Banks provides such offered quotations, LIBOR for the next
     Interest Accrual Period (as such term is defined in the related Prospectus
     Supplement) shall be whichever is the higher of (i) LIBOR as determined on
     the previous LIBOR Determination Date or (ii) the Reserve Interest Rate.
     The 'Reserve Interest Rate' shall be the rate per annum which the
     Calculation Agent determines to be either (i) the arithmetic mean (rounded
     upwards if necessary to the nearest whole multiple of 1/32%) of the
     one-month United States dollar lending rates that New York City banks
     selected by the Calculation Agent are quoting, on the relevant LIBOR
     Determination Date, to the principal London offices of at least two of the
     Reference Banks to which such quotations are, in the opinion of the
     Calculation Agent being so made, or (ii) in the event that the Calculation
     Agent can determine no such arithmetic mean, the lowest one-month United
     States dollar lending rate which New York City banks selected by the
     Calculation Agent are quoting on such LIBOR Determination Date to leading
     European banks.
 
          (c) If on any LIBOR Determination Date for a class specified in the
     related Prospectus Supplement, the Calculation Agent is required but is
     unable to determine the Reserve Interest Rate in the manner provided in
     paragraph (b) above, LIBOR for the next Interest Accrual Period shall be
     LIBOR as determined on the preceding LIBOR Determination Date, or, in the
     case of the first LIBOR Determination Date, LIBOR shall be deemed to be the
     per annum rate specified as such in the related Prospectus Supplement.
 
     Each Reference Bank (i) shall be a leading bank engaged in transactions in
Eurodollar deposits in the international Eurocurrency market; (ii) shall not
control, be controlled by, or be under common control with the Calculation
Agent; and (iii) shall have an established place of business in London. If any
such Reference Bank should be unwilling or unable to act as such or if
appointment of any such Reference Bank is terminated, another leading bank
meeting the criteria specified above will be appointed.
 
     The establishment of LIBOR on each LIBOR Determination Date by the
Calculation Agent and its calculation of the rate of interest for the applicable
classes for the related Interest Accrual Period shall (in the absence of
manifest error) be final and binding.
 
COFI
 
     The Eleventh District Cost of Funds Index is designed to represent the
monthly weighted average cost of funds for savings institutions in Arizona,
California and Nevada that are member institutions of the Eleventh Federal Home
Loan Bank District (the 'Eleventh District'). The Eleventh District Cost of
Funds Index for a particular month reflects the interest costs paid on all types
of funds held by Eleventh District member institutions and is calculated by
dividing the cost of funds by the average of the total amount of those funds
outstanding at the end of that month and of the prior month and annualizing and
adjusting the result to reflect the actual number of days in the particular
month. If necessary, before these calculations are made, the component figures
are adjusted by the Federal Home Loan Bank of San Francisco ('FHLBSF') to
neutralize the effect of events such as member institutions leaving the Eleventh
District or acquiring institutions outside the Eleventh District. The Eleventh
District Cost of Funds Index is weighted to reflect the relative amount of each
type of funds held at the end of the relevant month. The major components of
funds of Eleventh District member institutions are: (i) savings deposits, (ii)
time deposits, (iii) FHLBSF advances, (iv) repurchase agreements and (v) all
other borrowings. Because the component funds represent a variety of maturities
whose costs may react in different ways to changing conditions, the Eleventh
District Cost of Funds Index does not necessarily reflect current market rates.
 
     A number of factors affect the performance of the Eleventh District Cost of
Funds Index, which may cause it to move in a manner different from indices tied
to specific interest rates, such as United States Treasury bills or LIBOR.
Because the liabilities upon which the Eleventh District Cost of Funds Index is
based were issued at various times under various market conditions and with
various maturities, the Eleventh District Cost of Funds Index may not
necessarily reflect the prevailing market interest rates on new liabilities of
similar maturities. Moreover, as stated above, the Eleventh District Cost of
Funds Index is designed to represent the average cost of funds for Eleventh
District savings institutions for the month prior to the month in which it its
due to be
 
                                       36
 

<PAGE>
<PAGE>

published. Additionally, the Eleventh District Cost of Funds Index may not
necessarily move in the same direction as market interest rates at all times,
since as longer term deposits or borrowings mature and are renewed at prevailing
market interest rates, the Eleventh District Cost of Funds Index is influenced
by the differential between the prior and the new rates on those deposits or
borrowings. In addition, movements of the Eleventh District Cost of Funds Index,
as compared to other indices tied to specific interest rates, may be affected by
changes instituted by the FHLBSF in the method used to calculate the Eleventh
District Cost of Funds Index.
 
     The FHLBSF publishes the Eleventh District Cost of Funds Index in its
monthly Information Bulletin. Any individual may request regular receipt by mail
of Information Bulletins by writing the Federal Home Loan Bank of San Francisco,
P.O. Box 7948, 600 California Street, San Francisco, California 94120, or by
calling (415) 616-1000. The Eleventh District Cost of Funds Index may also be
obtained by calling the FHLBSF at (415) 616-2600.
 
     The FHLBSF has stated in its Information Bulletin that the Eleventh
District Cost of Funds Index for a month 'will be announced on or near the last
working day' of the following month and also has stated that it 'cannot
guarantee the announcement' of such index on an exact date. So long as such
index for a month is announced on or before the tenth day of the second
following month, the interest rate for each class of Securities of a Series as
to which the applicable interest rate is determined by reference to an index
denominated as COFI (each, a class of 'COFI Securities') for the Interest
Accrual Period commencing in such second following month will be based on the
Eleventh District Cost of Funds Index for the second preceding month. If
publication is delayed beyond such tenth day, such interest rate will be based
on the Eleventh District Cost of Funds Index for the third preceding month.
 
     Unless otherwise specified in the related Prospectus Supplement, if on the
tenth day of the month in which any Interest Accrual Period commences for a
class of COFI Securities the most recently published Eleventh District Cost of
Funds Index relates to a month prior to the third preceding month, the index for
such current Interest Accrual Period and for each succeeding Interest Accrual
Period will, except as described in the next to last sentence of this paragraph,
be based on the National Monthly Median Cost of Funds Ratio to SAIF-Insured
Institutions (the 'National Cost of Funds Index') published by the Office of
Thrift Supervision (the 'OTS') for the third preceding month (or the fourth
preceding month if the National Cost of Funds Index for the third preceding
month has not been published on such tenth day of an Interest Accrual Period).
Information on the National Cost of Funds Index may be obtained by writing the
OTS at 1700 G Street, N.W., Washington, D.C. 20552 or calling (202) 906-6677,
and the current National Cost of Funds Index may be obtained by calling (202)
906-6988. If on any such tenth day of the month in which an Interest Accrual
Period commences the most recently published National Cost of Funds Index
relates to a month prior to the fourth preceding month, the applicable index for
such Interest Accrual Period and each succeeding Interest Accrual Period will be
based on LIBOR, as determined by the Calculation Agent in accordance with the
Agreement relating to such Series of Securities. A change of index from the
Eleventh District Cost of Funds Index to an alternative index will result in a
change in the index level, and, particularly if LIBOR is the alternative index,
could increase its volatility.
 
     The establishment of COFI by the Calculation Agent and its calculation of
the rates of interest for the applicable classes for the related Interest
Accrual Period shall (in the absence of manifest error) be final and binding.
 
Treasury Index
 
     Unless otherwise specified in the related Prospectus Supplement, on the
Treasury Index Determination Date (as such term is defined in the related
Prospectus Supplement) for each class of Securities of a Series as to which the
applicable interest rate is determined by reference to an index denominated as a
Treasury Index, the Calculation Agent will ascertain the Treasury Index for
Treasury securities of the maturity and for the period (or, if applicable, date)
specified in the related Prospectus Supplement. Unless otherwise specified in
the related Prospectus Supplement, the Treasury Index for any period means the
average of the yield for each business day during the period specified therein
(and for any date means the yield for such date), expressed as a per annum
percentage rate, on (i) U.S Treasury securities adjusted to the 'constant
maturity' (as further described below) specified in such Prospectus Supplement
or (ii) if no 'constant maturity' is so specified, U.S. Treasury securities
trading on the secondary market having the maturity specified in such Prospectus
Supplement, in each case as published by the Federal Reserve Board in its
Statistical Release No. H.15(519). Statistical Release No.

H.15(519) is published on Monday or Tuesday of each week and may be obtained by
writing or calling the Publications Department at the Board of Governors of the
Federal Reserve System, 21st and C Streets, Washington, D.C. 20551 (202)
452-3244. If the Calculation Agent has not yet received Statistical Release No.
H.15(519) for such week, then it will use such Statistical Release from the
immediately preceding week.
 
     Yields on U.S. Treasury securities at 'constant maturity' are derived from
the U.S. Treasury's daily yield curve. This curve, which relates the yield on a
security to its time to maturity, is based on the closing market bid yields on
actively traded Treasury securities in the over-the-counter market. These market
yields are calculated from composites of quotations reported by five leading
U.S. Government securities dealers to the Federal Reserve Bank of New York. This
method provides a yield for a given maturity even if no security with that exact
maturity is outstanding. In the event that the Treasury Index is no longer
published, a new index based upon comparable data and methodology will be
designated in accordance with the Agreement relating to the particular Series of
Securities. The Calculation Agent's determination of the Treasury Index, and its
calculation of the rates of interest for the applicable classes for the related
Interest Accrual Period shall (in the absence of manifest error) be final and
binding.
 
Prime Rate
 
     Unless otherwise specified in the related Prospectus Supplement, on the
Prime Rate Determination Date (as such term is defined in the related Prospectus
Supplement) for each class of Securities of a Series as to which the applicable
interest rate is determined by reference to an index denominated as the Prime
Rate, the Calculation Agent will ascertain the Prime Rate for the related
Interest Accrual Period. Unless otherwise specified in the related Prospectus
Supplement, the Prime Rate for an Interest Accrual Period will be the 'Prime
Rate' as published in the 'Money Rates' section of The Wall Street Journal (or
if not so published, the 'Prime Rate' as published in a newspaper of general
circulation selected by the Calculation Agent in its sole discretion) on the
related Prime Rate Determination Date. If a prime rate range is given, then the
average of such range will be used. In the event that the Prime Rate is no
longer published, a new index based upon comparable data and methodology will be
designated in accordance with the Agreement relating to the particular Series of
Securities. The Calculation Agent's determination of the Prime Rate and its
calculation of the rates of interest for the related Interest Accrual Period
shall (in the absence of manifest error) be final and binding.
 
BOOK-ENTRY REGISTRATION OF SECURITIES
 
     As described in the related Prospectus Supplement, if not issued in fully
registered form, each class of Securities will be registered as book-entry
certificates (the 'Book-Entry Securities'). Persons acquiring beneficial
ownership interests in the Securities ('Security Owners') will hold their
Securities through the Depository Trust Company ('DTC') in the United States, or
CEDEL or Euroclear (in Europe) if they are participants of such systems, or
indirectly through organizations which are participants in such systems. The
Book-Entry Securities will be issued in one or more certificates which equal the
aggregate principal balance of the Securities and will initially be registered
in the name of Cede & Co., the nominee of DTC. CEDEL and Euroclear will hold
omnibus positions on behalf of their participants through customers' securities
accounts in CEDEL's and Euroclear's names on the books of their respective
depositaries which in turn will hold such positions in customers' securities
accounts in the depositaries' names on the books of DTC. Citibank, N.A., will
act as depositary for CEDEL and The Chase Manhattan Bank will act as depositary
for Euroclear (in such capacities, individually the 'Relevant Depositary' and
collectively the 'European Depositaries'). Except as described below, no person
acquiring a Book-Entry Security (each, a 'beneficial owner') will be entitled to
receive a physical certificate representing such Security (a 'Definitive
Security'). Unless and until Definitive Securities are issued, it is anticipated
that the only 'Securityholders' of the Securities will be Cede & Co., as nominee
of DTC. Security Owners are only permitted to exercise their rights indirectly
through Participants and DTC.
 
     The beneficial owner's ownership of a Book-Entry Security will be recorded
on the records of the brokerage firm, bank, thrift institution or other
financial intermediary (each, a 'Financial Intermediary') that maintains the
beneficial owner's account for such purpose. In turn, the Financial
Intermediary's ownership of such Book-Entry Security will be recorded on the
records of DTC (or of a participating firm that acts as agent for the Financial
Intermediary, whose interest will in turn be recorded on the records of DTC, if
the beneficial
 
                                       38
 

<PAGE>
<PAGE>

owner's Financial Intermediary is not a DTC participant, and on the records of
CEDEL or Euroclear, as appropriate).
 
     Security Owners will receive all distributions of principal of, and
interest on, the Securities from the Trustee through DTC and DTC participants.
While the Securities are outstanding (except under the circumstances described
below), under the rules, regulations and procedures creating and affecting DTC
and its operations (the 'Rules'), DTC is required to make book-entry transfers
among Participants on whose behalf it acts with respect to the Securities and is
required to receive and transmit distributions of principal of, and interest on,
the Securities. Participants and indirect participants with whom Security Owners
have accounts with respect to Securities are similarly required to make
book-entry transfers and receive and transmit such distributions on behalf of
their respective Security Owners. Accordingly, although Security Owners will not
possess certificates, the Rules provide a mechanism by which Security Owners
will receive distributions and will be able to transfer their interest.
 
     Security Owners will not receive or be entitled to receive certificates
representing their respective interests in the Securities, except under the
limited circumstances described below. Unless and until Definitive Securities
are issued, Security Owners who are not Participants may transfer ownership of
Securities only through Participants and indirect participants by instructing
such Participants and indirect participants to transfer Securities, by
book-entry transfer, through DTC for the account of the purchasers of such
Securities, which account is maintained with their respective Participants.
Under the Rules and in accordance with DTC's normal procedures, transfers of
ownership of Securities will be executed through DTC and the accounts of the
respective Participants at DTC will be debited and credited. Similarly, the
Participants and indirect participants will make debits or credits, as the case
may be, on their records on behalf of the selling and purchasing Security
Owners.
 
     Because of time zone differences, credits of securities received in CEDEL
or Euroclear as a result of a transaction with a Participant will be made during
subsequent securities settlement processing and dated the business day following
the DTC settlement date. Such credits or any transactions in such securities
settled during such processing will be reported to the relevant Euroclear or
CEDEL Participants on such business day. Cash received in CEDEL or Euroclear as
a result of sales of securities by or through a CEDEL Participant (as defined
herein) or Euroclear Participant (as defined herein) to a DTC Participant will
be received with value on the DTC settlement date but will be available in the
relevant CEDEL or Euroclear cash account only as of the business day following
settlement in DTC.
 
     Transfers between Participants will occur in accordance with DTC rules.
Transfers between CEDEL Participants and Euroclear Participants will occur in
accordance with their respective rules and operating procedures.
 
     Cross-market transfers between persons holding directly or indirectly
through DTC, on the one hand, and directly or indirectly through CEDEL
Participants or Euroclear Participants, on the other, will be effected in DTC in
accordance with DTC rules on behalf of the relevant European international
clearing system by the Relevant Depositary; however, such cross-market
transactions will require delivery of instructions to the relevant European
international clearing system by the counterparty in such system in accordance
with its rules and procedures and within its established deadlines (European
time). The relevant European international clearing system will, if the
transaction meets its settlement requirements, deliver instructions to the
Relevant Depositary to take action to effect final settlement on its behalf by
delivering or receiving securities in DTC, and making or receiving payment in
accordance with normal procedures for same day funds settlement applicable to
DTC. CEDEL Participants and Euroclear Participants may not deliver instructions
directly to the European Depositaries.
 
     CEDEL is incorporated under the laws of Luxembourg as a professional
depository. CEDEL holds securities for its participating organizations ('CEDEL
Participants') and facilitates the clearance and settlement of securities
transactions between CEDEL Participants through electronic book-entry changes in
accounts of CEDEL Participants, thereby eliminating the need for physical
movement of certificates. Transactions may be settled in CEDEL in any of 28
currencies, including United States dollars. CEDEL provides to its CEDEL
Participants, among other things, services for safekeeping, administration,
clearance and settlement of internationally traded securities and securities
lending and borrowing. CEDEL interfaces with domestic markets in several
countries. As a professional depository, CEDEL is subject to regulation by the
Luxembourg Monetary Institute. CEDEL participants are recognized financial
institutions around the world, including underwriters,
 
                                       39
 

<PAGE>
<PAGE>

securities brokers and dealers, banks, trust companies, clearing corporations
and certain other organizations. Indirect access to CEDEL is also available to
others, such as banks, brokers, dealers and trust companies that clear through
or maintain a custodial relationship with a CEDEL Participant, either directly
or indirectly.
 
     Euroclear was created in 1968 to hold securities for its participants
('Euroclear Participants') and to clear and settle transactions between
Euroclear Participants through simultaneous electronic book-entry delivery
against payment, thereby eliminating the need for physical movement of
certificates and any risk from lack of simultaneous transfers of securities and
cash. Transactions may be settled in any of 32 currencies, including United
States dollars. Euroclear includes various other services, including securities
lending and borrowing and interfaces with domestic markets in several countries
generally similar to the arrangements for cross-market transfers with DTC
described above. Euroclear is operated by the Brussels, Belgium office of Morgan
Guaranty Trust Company of New York ('Morgan' and in such capacity, the
'Euroclear Operator'), under contract with Euroclear Clearance Systems S.C., a
Belgian cooperative corporation (the 'Belgian Cooperative'). All operations are
conducted by Morgan, and all Euroclear securities clearance accounts and
Euroclear cash accounts are accounts with the Euroclear Operator, not the
Belgian Cooperative. The Belgian Cooperative establishes policy for Euroclear on
behalf of Euroclear Participants. Euroclear Participants include banks
(including central banks), securities brokers and dealers and other professional
financial intermediaries. Indirect access to Euroclear is also available to
other firms that clear through or maintain a custodial relationship with a
Euroclear Participant, either directly or indirectly.
 
     Morgan is the Belgian branch of a New York banking corporation which is a
member bank of the Federal Reserve System. As such, it is regulated and examined
by the Board of Governors of the Federal Reserve System and the New York State
Banking Department, as well as the Belgian Banking Commission.
 
     Securities clearance accounts and cash accounts with Morgan are governed by
the Terms and Conditions Governing Use of Euroclear and the related Operating
Procedures of the Euroclear System and applicable Belgian law (collectively, the
'Terms and Conditions'). The Terms and Conditions govern transfers of securities
and cash within Euroclear, withdrawals of securities and cash from Euroclear,
and receipts of payments with respect to securities in Euroclear. All securities
in Euroclear are held on a fungible basis without attribution of specific
certificates to specific securities clearance accounts. The Euroclear Operator
acts under the Terms and Conditions only on behalf of Euroclear Participants,
and has no record of or relationship with persons holding through Euroclear
Participants.
 
     Under a book-entry format, beneficial owners of the Book-Entry Securities
may experience some delay in their receipt of payments, since such payments will
be forwarded by the Trustee to Cede & Co., as nominee of DTC. Distributions with
respect to Securities held through CEDEL or Euroclear will be credited to the
cash accounts of CEDEL Participants or Euroclear Participants in accordance with
the relevant system's rules and procedures, to the extent received by the
Relevant Depositary. Such distributions will be subject to tax reporting in
accordance with relevant United States tax laws and regulations. See 'Federal
Income Tax Consequences -- Tax Treatment of Foreign Investors' and ' -- Tax
Consequences to Holders of the Notes -- Backup Withholding' herein. Because DTC
can only act on behalf of Financial Intermediaries, the ability of a beneficial
owner to pledge Book-Entry Securities to persons or entities that do not
participate in the Depository system may be limited due to the lack of physical
certificates for such Book-Entry Securities. In addition, issuance of the Book-
Entry Securities in book-entry form may reduce the liquidity of such Securities
in the secondary market since certain potential investors may be unwilling to
purchase Securities for which they cannot obtain physical certificates.
 
     Monthly and annual reports on the Trust will be provided to Cede & Co., as
nominee of DTC, and may be made available by Cede & Co. to beneficial owners
upon request, in accordance with the rules, regulations and procedures creating
and affecting the Depository, and to the Financial Intermediaries to whose DTC
accounts the Book-Entry Securities of such beneficial owners are credited.
 
     DTC has advised the Trustee that, unless and until Definitive Securities
are issued, DTC will take any action permitted to be taken by the holders of the
Book-Entry Securities under the applicable Agreement only at the direction of
one or more Financial Intermediaries to whose DTC accounts the Book-Entry
Securities are credited, to the extent that such actions are taken on behalf of
Financial Intermediaries whose holdings include such Book-Entry Securities.
CEDEL or the Euroclear Operator, as the case may be, will take any other action
permitted to be taken by a Securityholder under the Agreement on behalf of a
CEDEL Participant or Euroclear Participant only in accordance with its relevant
rules and procedures and subject to the ability of the Relevant
 
                                       40
 

<PAGE>
<PAGE>

Depositary to effect such actions on its behalf through DTC. DTC may take
actions, at the direction of the related Participants, with respect to some
Securities which conflict with actions taken with respect to other Securities.
 
     Upon the occurrence of any of the events described in the immediately
preceding paragraph, the Trustee will be required to notify all beneficial
owners of the occurrence of such event and the availability through DTC of
Definitive Securities. Upon surrender by DTC of the global certificate or
certificates representing the Book-Entry Securities and instructions for
re-registration, the Trustee will issue Definitive Securities, and thereafter
the Trustee will recognize the holders of such Definitive Securities as
Securityholders under the applicable Agreement.
 
     Although DTC, CEDEL and Euroclear have agreed to the foregoing procedures
in order to facilitate transfers of Securities among participants of DTC, CEDEL
and Euroclear, they are under no obligation to perform or continue to perform
such procedures and such procedures may be discontinued at any time.
 
     None of the Master Servicer, the Depositor or the Trustee will have any
responsibility for any aspect of the records relating to or payments made on
account of beneficial ownership interests of the Book-Entry Securities held by
Cede & Co., as nominee of DTC, or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.
 
                               CREDIT ENHANCEMENT
 
GENERAL
 
     Credit enhancement may be provided with respect to one or more classes of a
Series of Securities or with respect to the related Trust Fund Assets. Credit
enhancement may be in the form of a limited financial guaranty policy issued by
an entity named in the related Prospectus Supplement, the subordination of one
or more classes of the Securities of such Series, the establishment of one or
more Reserve Accounts, the use of a cross-collateralization feature, use of a
mortgage pool insurance policy, FHA Insurance, VA Guarantee, bankruptcy bond,
special hazard insurance policy, surety bond, letter of credit, guaranteed
investment contract, overcollateralization, or another method of credit
enhancement contemplated herein and described in the related Prospectus
Supplement, or any combination of the foregoing. Unless otherwise specified in
the related Prospectus Supplement, credit enhancement will not provide
protection against all risks of loss and will not guarantee repayment of the
entire principal balance of the Securities and interest thereon. If losses occur
which exceed the amount covered by credit enhancement or which are not covered
by the credit enhancement, Securityholders will bear their allocable share of
any deficiencies.
 
SUBORDINATION
 
     If so specified in the related Prospectus Supplement, protection afforded
to holders of one or more classes of Securities of a Series by means of the
subordination feature may be accomplished by the preferential right of holders
of one or more other classes of such Series (the 'Senior Securities') to
distributions in respect of scheduled principal, Principal Prepayments, interest
or any combination thereof that otherwise would have been payable to holders of
Subordinated Securities under the circumstances and to the extent specified in
the related Prospectus Supplement. Protection may also be afforded to the
holders of Senior Securities of a Series by: (i) reducing the ownership interest
(if applicable) of the related Subordinated Securities; (ii) a combination of
the immediately preceding sentence and clause (i) above; or (iii) as otherwise
described in the related Prospectus Supplement. If so specified in the related
Prospectus Supplement, delays in receipt of scheduled payments on the Loans and
losses on defaulted Loans may be borne first by the various classes of
Subordinated Securities and thereafter by the various classes of Senior
Securities, in each case under the circumstances and subject to the limitations
specified in such Prospectus Supplement. The aggregate distributions in respect
of delinquent payments on the Loans over the lives of the Securities or at any
time, the aggregate losses in respect of defaulted Loans which must be borne by
the Subordinated Securities by virtue of subordination and the amount of the
distributions otherwise distributable to the Subordinated Securityholders that
will be distributable to Senior Securityholders on any Distribution Date may be
limited as specified in the related Prospectus Supplement. If aggregate
distributions in respect of delinquent payments on the Loans or aggregate losses
in respect of such Loans were to exceed an amount specified in the related
Prospectus Supplement, holders of Senior Securities would experience losses on
the Securities.
 
                                       41
 

<PAGE>
<PAGE>

     In addition to or in lieu of the foregoing, if so specified in the related
Prospectus Supplement, all or any portion of distributions otherwise payable to
holders of Subordinated Securities on any Distribution Date may instead be
deposited into one or more Reserve Accounts established with the Trustee or
distributed to holders of Senior Securities. Such deposits may be made on each
Distribution Date, for specified periods or until the balance in the Reserve
Account has reached a specified amount and, following payments from the Reserve
Account to holders of Senior Securities or otherwise, thereafter to the extent
necessary to restore the balance in the Reserve Account to required levels, in
each case as specified in the related Prospectus Supplement. Amounts on deposit
in the Reserve Account may be released to the holders of certain classes of
Securities at the times and under the circumstances specified in such Prospectus
Supplement.
 
     If specified in the related Prospectus Supplement, various classes of
Senior Securities and Subordinated Securities may themselves be subordinate in
their right to receive certain distributions to other classes of Senior and
Subordinated Securities, respectively, through a cross-collateralization
mechanism or otherwise.
 
     As between classes of Senior Securities and as between classes of
Subordinated Securities, distributions may be allocated among such classes (i)
in the order of their scheduled final distribution dates, (ii) in accordance
with a schedule or formula, (iii) in relation to the occurrence of events, or
(iv) otherwise, in each case as specified in the related Prospectus Supplement.
As between classes of Subordinated Securities, payments to holders of Senior
Securities on account of delinquencies or losses and payments to any Reserve
Account will be allocated as specified in the related Prospectus Supplement.
 
LETTER OF CREDIT
 
     The letter of credit, if any, with respect to a Series of Securities will
be issued by the bank or financial institution specified in the related
Prospectus Supplement (the 'L/C Bank'). Under the letter of credit, the L/C Bank
will be obligated to honor drawings thereunder in an aggregate fixed dollar
amount, net of unreimbursed payments thereunder, equal to the percentage
specified in the related Prospectus Supplement of the aggregate principal
balance of the Loans on the related Cut-off Date or of one or more Classes of
Securities (the 'L/C Percentage'). If so specified in the related Prospectus
Supplement, the letter of credit may permit drawings in the event of losses not
covered by insurance policies or other credit support, such as losses arising
from damage not covered by standard hazard insurance policies, losses resulting
from the bankruptcy of a borrower and the application of certain provisions of
the federal Bankruptcy Code, or losses resulting from denial of insurance
coverage due to misrepresentations in connection with the origination of a Loan.
The amount available under the letter of credit will, in all cases, be reduced
to the extent of the unreimbursed payments thereunder. The obligations of the
L/C Bank under the letter of credit for each Series of Securities will expire at
the earlier of the date specified in the related Prospectus Supplement or the
termination of the Trust Fund. See 'The Agreements -- Termination: Optional
Termination.' A copy of the letter of credit for a Series, if any, will be filed
with the Commission as an exhibit to a Current Report on Form 8-K to be filed
within 15 days of issuance of the Securities of the related Series.
 
INSURANCE POLICIES, SURETY BONDS AND GUARANTIES
 
     If so provided in the Prospectus Supplement for a Series of Securities,
deficiencies in amounts otherwise payable on such Securities or certain classes
thereof will be covered by insurance policies and/or surety bonds provided by
one or more insurance companies or sureties. Such instruments may cover, with
respect to one or more classes of Securities of the related series, timely
distributions of interest and/or full distributions of principal on the basis of
a schedule of principal distributions set forth in or determined in the manner
specified in the related Prospectus Supplement. In addition, if specified in the
related Prospectus Supplement, a Trust Fund may also include bankruptcy bonds,
special hazard insurance policies, other insurance or guaranties for the purpose
of (i) maintaining timely payments or providing additional protection against
losses on the assets included in such Trust Fund, (ii) paying administrative
expenses or (iii) establishing a minimum reinvestment rate on the payments made
in respect of such assets or principal payment rate on such assets. Such
arrangements may include agreements under which Securityholders are entitled to
receive amounts deposited in various accounts held by the Trustee upon the terms
specified in such Prospectus Supplement. A copy of any such instrument for a
series will be filed with the Commission as an exhibit to a Current Report on
Form 8-K to be filed with the Commission within 15 days of issuance of the
Securities of the related series.

<PAGE>
<PAGE>

OVER-COLLATERALIZATION
 
     If so provided in the Prospectus Supplement for a Series of Securities, a
portion of the interest payment on each Loan may be applied as an additional
distribution in respect of principal to reduce the principal balance of a
certain class or classes of Securities and, thus, accelerate the rate of payment
of principal on such class or classes of Securities.
 
RESERVE ACCOUNTS
 
     If specified in the related Prospectus Supplement, credit support with
respect to a Series of Securities will be provided by the establishment and
maintenance with the Trustee for such Series of Securities, in trust, of one or
more Reserve Accounts for such Series. The related Prospectus Supplement will
specify whether or not any such Reserve Accounts will be included in the Trust
Fund for such Series.
 
     The Reserve Account for a Series will be funded (i) by the deposit therein
of cash, United States Treasury securities, instruments evidencing ownership of
principal or interest payments thereon, letters of credit, demand notes,
certificates of deposit or a combination thereof in the aggregate amount
specified in the related Prospectus Supplement, (ii) by the deposit therein from
time to time of certain amounts, as specified in the related Prospectus
Supplement to which the Subordinate Securityholders, if any, would otherwise be
entitled or (iii) in such other manner as may be specified in the related
Prospectus Supplement.
 
     Any amounts on deposit in the Reserve Account and the proceeds of any other
instrument upon maturity will be held in cash or will be invested in 'Permitted
Investments' which may include (i) obligations of the United States or any
agency thereof, provided such obligations are backed by the full faith and
credit of the United States; (ii) general obligations of or obligations
guaranteed by any state of the United States or the District of Columbia
receiving the highest long-term debt rating of each Rating Agency rating the
related Series of Securities, or such lower rating as will not result in the
downgrading or withdrawal of the ratings then assigned to such Securities by
each such Rating Agency; (iii) commercial paper issued by Countrywide Home
Loans, Inc. or any of its affiliates; provided that such commercial paper is
rated no lower than the rating specified in the related Prospectus Supplement;
(iv) commercial or finance company paper which is then receiving the highest
commercial or finance company paper rating of each such Rating Agency, or such
lower rating as will not result in the downgrading or withdrawal of the ratings
then assigned to such Securities by each such Rating Agency; (v) certificates of
deposit, demand or time deposits, or bankers' acceptances issued by any
depository institution or trust company incorporated under the laws of the
United States or of any state thereof and subject to supervision and examination
by federal and/or state banking authorities, provided that the commercial paper
and/or long term unsecured debt obligations of such depository institution or
trust company (or in the case of the principal depository institution in a
holding company system, the commercial paper or long-term unsecured debt
obligations of such holding company, but only if Moody's Investors Service, Inc.
('Moody's') is not a Rating Agency) are then rated one of the two highest
long-term and the highest short-term ratings of each such Rating Agency for such
securities, or such lower ratings as will not result in the downgrading or
withdrawal of the rating then assigned to such Securities by any such Rating
Agency; (vi) demand or time deposits or certificates of deposit issued by any
bank or trust company or savings institution to the extent that such deposits
are fully insured by the FDIC; (vii) guaranteed reinvestment agreements issued
by any bank, insurance company or other corporation containing, at the time of
the issuance of such agreements, such terms and conditions as will not result in
the downgrading or withdrawal of the rating then assigned to such Securities by
any such Rating Agency; (viii) repurchase obligations with respect to any
security described in clauses (i) and (ii) above, in either case entered into
with a depository institution or trust company (acting as principal) described
in clause (v) above; (ix) securities (other than stripped bonds, stripped
coupons or instruments sold at a purchase price in excess of 115% of the face
amount thereof) bearing interest or sold at a discount issued by any corporation
incorporated under the laws of the United States or any state thereof which, at
the time of such investment, have one of the two highest ratings of each Rating
Agency (except if the Rating Agency is Moody's, such rating shall be the highest
commercial paper rating of Moody's for any such securities), or such lower
rating as will not result in the downgrading or withdrawal of the rating then
assigned to such Securities by any such Rating Agency, as evidenced by a signed
writing delivered by each such Rating Agency; (x) interests in any money market
fund which at the date of acquisition of the interests in such fund and
throughout the time such interests are held in such fund has the highest
applicable rating by each such Rating Agency or such lower rating as will not
result in the downgrading or withdrawal of the ratings then assigned to
 
                                       43
 

<PAGE>
<PAGE>

such Securities by each such Rating Agency; (xi) short term investment funds
sponsored by any trust company or national banking association incorporated
under the laws of the United States or any state thereof which on the date of
acquisition has been rated by each such Rating Agency in their respective
highest applicable rating category or such lower rating as will not result in
the downgrading or withdrawal of the ratings then assigned to such Securities by
each such Rating Agency; and (xii) such other investments having a specified
stated maturity and bearing interest or sold at a discount acceptable to each
Rating Agency as will not result in the downgrading or withdrawal of the rating
then assigned to such Securities by any such Rating Agency, as evidenced by a
signed writing delivered by each such Rating Agency; provided that no such
instrument shall be a Permitted Investment if such instrument evidences the
right to receive interest only payments with respect to the obligations
underlying such instrument; and provided, further, that no investment specified
in clause (x) or clause (xi) above shall be a Permitted Investment for any
Pre-Funding Account or any related Capitalized Interest Account. If a letter of
credit is deposited with the Trustee, such letter of credit will be irrevocable.
Unless otherwise specified in the related Prospectus Supplement, any instrument
deposited therein will name the Trustee, in its capacity as trustee for the
holders of the Securities, as beneficiary and will be issued by an entity
acceptable to each Rating Agency that rates the Securities of the related
Series. Additional information with respect to such instruments deposited in the
Reserve Accounts will be set forth in the related Prospectus Supplement.
 
     Any amounts so deposited and payments on instruments so deposited will be
available for withdrawal from the Reserve Account for distribution to the
holders of Securities of the related Series for the purposes, in the manner and
at the times specified in the related Prospectus Supplement.
 
POOL INSURANCE POLICIES
 
     If specified in the related Prospectus Supplement, a separate pool
insurance policy ('Pool Insurance Policy') will be obtained for the Pool and
issued by the insurer (the 'Pool Insurer') named in such Prospectus Supplement.
Each Pool Insurance Policy will, subject to the limitations described below,
cover loss by reason of default in payment on Loans in the Pool in an amount
equal to a percentage specified in such Prospectus Supplement of the aggregate
principal balance of such Loans on the Cut-off Date which are not covered as to
their entire outstanding principal balances by Primary Mortgage Insurance
Policies. As more fully described below, the Master Servicer will present claims
thereunder to the Pool Insurer on behalf of itself, the Trustee and the holders
of the Securities of the related Series. The Pool Insurance Policies, however,
are not blanket policies against loss, since claims thereunder may only be made
respecting particular defaulted Loans and only upon satisfaction of certain
conditions precedent described below. Unless otherwise specified in the related
Prospectus Supplement, the Pool Insurance Policies will not cover losses due to
a failure to pay or denial of a claim under a Primary Mortgage Insurance Policy.
 
     Unless otherwise specified in the related Prospectus Supplement, the 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
Loan and a claim thereunder has been submitted and settled; (ii) hazard
insurance on the related 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 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 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 Loan at a price equal to the
principal balance thereof plus accrued and unpaid interest at the Loan Rate to
the date of such purchase and certain expenses incurred by the Master Servicer
on behalf of the Trustee and Securityholders, or (b) to pay the amount by which
the sum of the principal balance of the defaulted Loan plus accrued and unpaid
interest at the Loan Rate to the date of payment of the claim and the
aforementioned expenses exceeds the proceeds received from an approved sale of
the 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 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 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
Securityholders on liquidation of the Loan after reimbursement
 
                                       44

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 Pool Insurance Policy or any related Primary Mortgage Insurance
Policy.
 
     Unless otherwise specified in the related Prospectus Supplement, the Pool
Insurance Policy will not 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 Loan,
including misrepresentation by the borrower, the originator or persons involved
in the origination thereof, or (ii) failure to construct a 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 events might give rise to an
obligation on the part of such Seller to repurchase the defaulted Loan if the
breach cannot be cured by such Seller. No Pool Insurance Policy will cover (and
many Primary Mortgage Insurance Policies do not cover) a claim in respect of a
defaulted Loan occurring when the servicer of such 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 Pool Insurance Policy will be reduced
over the life of the related Securities by the aggregate dollar amount of claims
paid less the aggregate of the net amounts realized by the Pool Insurer upon
disposition of all foreclosed properties. The amount of claims paid will include
certain expenses incurred by the Master Servicer as well as accrued interest on
delinquent Loans to the date of payment of the claim, unless otherwise specified
in the related Prospectus Supplement. Accordingly, if aggregate net claims paid
under any Pool Insurance Policy reach the original policy limit, coverage under
that Pool Insurance Policy will be exhausted and any further losses will be
borne by the related Securityholders.
 
CROSS-COLLATERALIZATION
 
     If specified in the related Prospectus Supplement, the beneficial ownership
of separate groups of assets included in a Trust Fund may be evidenced by
separate classes of the related Series of Securities. In such case, credit
support may be provided by a cross-collateralization feature which requires that
distributions be made with respect to Securities evidencing a beneficial
ownership interest in, or secured by, one or more asset groups within the same
Trust Fund prior to distributions to Subordinated Securities evidencing a
beneficial ownership interest in, or secured by, one or more other asset groups
within such Trust Fund. Cross-collateralization may be provided by (i) the
allocation of certain excess amounts generated by one or more asset groups to
one or more other asset groups within the same Trust Fund or (ii) the allocation
of losses with respect to one or more asset groups to one or more other asset
groups within the same Trust Fund. Such excess amounts will be applied and/or
such losses will be allocated to the class or classes of Subordinated Securities
of the related Series then outstanding having the lowest rating assigned by any
Rating Agency or the lowest payment priority, in each case to the extent and in
the manner more specifically described in the related Prospectus Supplement. The
Prospectus Supplement for a Series which includes a cross-collateralization
feature will describe the manner and conditions for applying such
cross-collateralization feature.
 
     If specified in the related Prospectus Supplement, the coverage provided by
one or more of the forms of credit enhancement described in this Prospectus may
apply concurrently to two or more separate Trust Funds. If applicable, the
related Prospectus Supplement will identify the Trust Funds to which such credit
enhancement relates and the manner of determining the amount of coverage
provided to such Trust Funds thereby and of the application of such coverage to
the identified Trust Funds.

                      YIELD AND PREPAYMENT CONSIDERATIONS
 
     The yields to maturity and weighted average lives of the Securities will be
affected primarily by the amount and timing of principal payments received on or
in respect of the Trust Fund Assets included in the related Trust Fund. The
original terms to maturity of the Loans in a given Pool will vary depending upon
the type of Loans included therein. Each Prospectus Supplement will contain
information with respect to the type and maturities of the Loans in the related
Pool. The related Prospectus Supplement will specify the circumstances, if any,
under which the related Loans will be subject to prepayment penalties. The
prepayment experience on the Loans in a Pool will affect the weighted average
life of the related Series of Securities.
 
     The rate of prepayment on the Loans cannot be predicted. Home equity loans
and home improvement contracts have been originated in significant volume only
during the past few years and the Depositor is not aware of any publicly
available studies or statistics on the rate of prepayment of such loans.
Generally, home equity loans and home improvement contracts are not viewed by
borrowers as permanent financing. Accordingly, such Loans may experience a
higher rate of prepayment than traditional first mortgage loans. On the other
hand, because home equity loans such as the Revolving Credit Line Loans
generally are not fully amortizing, the absence of voluntary borrower
prepayments could cause rates of principal payments lower than, or similar to,
those of traditional fully-amortizing first mortgage loans. The prepayment
experience of the related Trust Fund may be affected by a wide variety of
factors, including general economic conditions, prevailing interest rate levels,
the availability of alternative financing, homeowner mobility and the frequency
and amount of any future draws on any Revolving Credit Line Loans. Other factors
that might be expected to affect the prepayment rate of a pool of home equity
mortgage loans or home improvement contracts include the amounts of, and
interest rates on, the underlying senior mortgage loans, and the use of first
mortgage loans as long-term financing for home purchase and subordinate mortgage
loans as shorter-term financing for a variety of purposes, including home
improvement, education expenses and purchases of consumer durables such as
automobiles. Accordingly, such Loans may experience a higher rate of prepayment
than traditional fixed-rate mortgage loans. In addition, any future limitations
on the right of borrowers to deduct interest payments on home equity loans for
federal income tax purposes may further increase the rate of prepayments of the
Loans. The enforcement of a 'due-on-sale' provision (as described below) will
have the same effect as a prepayment of the related Loan. See 'Certain Legal
Aspects of the Loans -- Due-on-Sale Clauses'. The yield to an investor who
purchases Securities in the secondary market at a price other than par will vary
from the anticipated yield if the rate of prepayment on the Loans is actually
different than the rate anticipated by such investor at the time such Securities
were purchased.
 
     Collections on Revolving Credit Line Loans may vary because, among other
things, borrowers may (i) make payments during any month as low as the minimum
monthly payment for such month or, during the interest-only period for certain
Revolving Credit Line Loans and, in more limited circumstances, Closed-End
Loans, with respect to which an interest-only payment option has been selected,
the interest and the fees and charges for such month or (ii) make payments as
high as the entire outstanding principal balance plus accrued interest and the
fees and charges thereon. It is possible that borrowers may fail to make the
required periodic payments. In addition, collections on the Loans may vary due
to seasonal purchasing and the payment habits of borrowers.
 
     Unless otherwise specified in the related Prospectus Supplement, all
conventional Loans will contain due-on-sale provisions permitting the mortgagee
to accelerate the maturity of the loan upon sale or certain transfers by the
borrower of the related Property. Loans insured by the FHA, and Single Family
Loans partially guaranteed by the VA, are assumable with the consent of the FHA
and the VA, respectively. Thus, the rate of prepayments on such Loans may be
lower than that of conventional Loans bearing comparable interest rates. The
Master Servicer generally will enforce any due-on-sale or due-on-encumbrance
clause, to the extent it has knowledge of the conveyance or further encumbrance
or the proposed conveyance or proposed further encumbrance of the Property and
reasonably believes that it is entitled to do so under applicable law; provided,
however, that the Master Servicer will not take any enforcement action that
would impair or threaten to impair any recovery under any related insurance
policy. See 'The Agreements -- Collection Procedures' and 'Certain Legal Aspects
of the Loans' for a description of certain provisions of each Agreement and
certain legal developments that may affect the prepayment experience on the
Loans.
 
     The rate of prepayments with respect to conventional mortgage loans has
fluctuated significantly in recent years. In general, if prevailing rates fall
significantly below the Loan Rates borne by the Loans, such Loans are
 
                                       46
 

<PAGE>
<PAGE>

more likely to be subject to higher prepayment rates than if prevailing interest
rates remain at or above such Loan Rates. Conversely, if prevailing interest
rates rise appreciably above the Loan Rates borne by the Loans, such Loans are
more likely to experience a lower prepayment rate than if prevailing rates
remain at or below such Loan Rates. However, there can be no assurance that such
will be the case.
 
     When a full prepayment is made on a Loan, the borrower is charged interest
on the principal amount of the Loan so prepaid only for the number of days in
the month actually elapsed up to the date of the prepayment, rather than for a
full month. The effect of prepayments in full will be to reduce the amount of
interest passed through or paid in the following month to holders of Securities
because interest on the principal amount of any Loan so prepaid will generally
be paid only to the date of prepayment. Partial prepayments in a given month may
be applied to the outstanding principal balances of the Loans so prepaid on the
first day of the month of receipt or the month following receipt. In the latter
case, partial prepayments will not reduce the amount of interest passed through
or paid in such month. Unless otherwise specified in the related Prospectus
Supplement, neither full nor partial prepayments will be passed through or paid
until the month following receipt.
 
     Even assuming that the Properties provide adequate security for the Loans,
substantial delays could be encountered in connection with the liquidation of
defaulted Loans and corresponding delays in the receipt of related proceeds by
Securityholders could occur. An action to foreclose on a Property securing a
Loan is regulated by state statutes and rules and is subject to many of the
delays and expenses of other lawsuits if defenses or counterclaims are
interposed, sometimes requiring several years to complete. Furthermore, in some
states an action to obtain a deficiency judgment is not permitted following a
nonjudicial sale of a property. In the event of a default by a borrower, these
restrictions among other things, may impede the ability of the Master Servicer
to foreclose on or sell the Property or to obtain liquidation proceeds
sufficient to repay all amounts due on the related Loan. In addition, the Master
Servicer will be entitled to deduct from related liquidation proceeds all
expenses reasonably incurred in attempting to recover amounts due on defaulted
Loans and not yet repaid, including payments to senior lienholders, legal fees
and costs of legal action, real estate taxes and maintenance and preservation
expenses.
 
     Liquidation expenses with respect to defaulted mortgage loans generally do
not vary directly with the outstanding principal balance of the loan at the time
of default. Therefore, assuming that a servicer took the same steps in realizing
upon a defaulted mortgage loan having a small remaining principal balance as it
would in the case of a defaulted mortgage loan having a large remaining
principal balance, the amount realized after expenses of liquidation would be
smaller as a percentage of the remaining principal balance of the small mortgage
loan than would be the case with the other defaulted mortgage loan having a
large remaining principal balance.
 
     Applicable state laws generally regulate interest rates and other charges,
require certain disclosures, and require licensing of certain originators and
servicers of Loans. In addition, most have other laws, public policy and general
principles of equity relating to the protection of consumers, unfair and
deceptive practices and practices which may apply to the origination, servicing
and collection of the Loans. Depending on the provisions of the applicable law
and the specific facts and circumstances involved, violations of these laws,
policies and principles may limit the ability of the Master Servicer to collect
all or part of the principal of or interest on the Loans, may entitle the
borrower to a refund of amounts previously paid and, in addition, could subject
the Master Servicer to damages and administrative sanctions.
 
     If the rate at which interest is passed through or paid to the holders of
Securities of a Series is calculated on a Loan-by-Loan basis, disproportionate
principal prepayments among Loans with different Loan Rates will affect the
yield on such Securities. In most cases, the effective yield to Securityholders
will be lower than the yield otherwise produced by the applicable Pass-Through
Rate or interest rate and purchase price, because while interest will accrue on
each Loan from the first day of the month (unless otherwise specified in the
related Prospectus Supplement), the distribution of such interest will not be
made earlier than the month following the month of accrual.
 
     Under certain circumstances, the Master Servicer, the holders of the
residual interests in a REMIC or any person specified in the related Prospectus
Supplement may have the option to purchase the assets of a Trust Fund thereby
effecting earlier retirement of the related Series of Securities. See 'The
Agreements -- Termination; Optional Termination'.

     The relative contribution of the various factors affecting prepayment may
vary from time to time. There can be no assurance as to the rate of payment of
principal of the Trust Fund Assets at any time or over the lives of the
Securities.
 
     The Prospectus Supplement relating to a Series of Securities will discuss
in greater detail the effect of the rate and timing of principal payments
(including prepayments), delinquencies and losses on the yield, weighted average
lives and maturities of such Securities.
 
                                 THE AGREEMENTS
 
     Set forth below is a description of the material provisions of each
Agreement which are not described elsewhere in this Prospectus. The description
is subject to, and qualified in its entirety by reference to, the provisions of
each Agreement. Where particular provisions or terms used in the Agreements are
referred to, such provisions or terms are as specified in the Agreements.
 
ASSIGNMENT OF THE TRUST FUND ASSETS
 
     Assignment of the Loans. At the time of issuance of the Securities of a
Series, the Depositor will cause the Loans comprising the related Trust Fund to
be assigned to the Trustee, without recourse, together with all principal and
interest received by or on behalf of the Depositor on or with respect to such
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 such Securities to the Depositor in exchange for the Loans. Each Loan
will be identified in a schedule appearing as an exhibit to the related
Agreement. Such schedule will include information as to the outstanding
principal balance of each Loan after application of payments due on or before
the Cut-off Date, as well as information regarding the Loan Rate or APR, the
maturity of the Loan, the Loan-to-Value Ratios or Combined Loan-to-Value Ratios,
as applicable, at origination and certain other information.
 
     Unless otherwise specified in the related Prospectus Supplement, the
Agreement will require that, within the time period specified therein, the
Depositor will also deliver or cause to be delivered to the Trustee (or to the
custodian hereinafter referred to) as to each Single Family Loan, Multifamily
Loan or Home Equity Loan, among other things, (i) the mortgage note or contract
endorsed without recourse in blank or to the order of the Trustee, (ii) the
mortgage, deed of trust or similar instrument (a 'Mortgage') with evidence of
recording indicated thereon (except for any Mortgage not returned from the
public recording office, in which case the Depositor will deliver or cause to be
delivered a copy of such Mortgage together with a certificate that the original
of such Mortgage was delivered to such recording office), (iii) an assignment of
the Mortgage to the Trustee, which assignment will be in recordable form in the
case of a Mortgage assignment, and (iv) such other security documents, including
those relating to any senior interests in the Property, as may be specified in
the related Prospectus Supplement or the related Agreement. Unless otherwise
specified in the related Prospectus Supplement, the Depositor will promptly
cause the assignments of the related Loans to be recorded in the appropriate
public office for real property records, except in states in which, 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 Loans that are Cooperative Loans, the Depositor will
cause to be delivered to the Trustee the related original cooperative note
endorsed without recourse in blank or to the order of the Trustee, the original
security agreement, the proprietary lease or occupancy agreement, the
recognition agreement, an executed financing agreement and the relevant stock
certificate, related blank stock powers and any other document specified in the
related Prospectus Supplement. The Depositor will cause to be filed in the
appropriate office an assignment and a financing statement evidencing the
Trustee's security interest in each Cooperative Loan.
 
     Unless otherwise specified in the related Prospectus Supplement, the
Depositor will as to each Home Improvement Contract, deliver or cause to be
delivered to the Trustee the original Home Improvement Contract and copies of
documents and instruments related to each Home Improvement Contract and, other
than in the case of unsecured Home Improvement Contracts, the security interest
in the Property securing such Home Improvement Contract. In order to give notice
of the right, title and interest of Securityholders to the Home Improvement
Contracts, the Depositor will cause a UCC-1 financing statement to be executed
by the Depositor
 
                                       48

<PAGE>

or the Seller identifying the Trustee as the secured party and identifying all
Home Improvement Contracts as collateral. Unless otherwise specified in the
related Prospectus Supplement, the Home Improvement Contracts will not be
stamped or otherwise marked to reflect their assignment to the Trustee.
Therefore, if, through negligence, fraud or otherwise, a subsequent purchaser
were able to take physical possession of the Home Improvement Contracts without
notice of such assignment, the interest of Securityholders in the Home
Improvement Contracts could be defeated. See 'Certain Legal Aspects of the
Loans -- The Home Improvement Contracts.'
 
     The Trustee (or the custodian hereinafter referred to) will review such
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 related Securityholders. Unless otherwise specified
in the related Prospectus Supplement, if any such document is found to be
missing or defective in any material respect, the Trustee (or such custodian)
will notify the Master Servicer and the Depositor, and the Master Servicer will
notify the related Seller. If such Seller cannot cure the omission or defect
within the time period specified in the related Prospectus Supplement after
receipt of such notice, such Seller will be obligated to either (i) purchase the
related Loan from the Trust Fund at the Purchase Price or (ii) if so specified
in the related Prospectus Supplement, remove such Loan from the Trust Fund and
substitute in its place one or more other Loans that meets certain requirements
set forth therein. There can be no assurance that a Seller will fulfill this
purchase or substitution obligation. Although the Master Servicer may be
obligated to enforce such obligation to the extent described above under 'Loan
Program -- Representations by Sellers; Repurchases', neither the Master Servicer
nor the Depositor will be obligated to purchase or replace such Loan if the
Seller defaults on its obligation, unless such breach also constitutes a breach
of the representations or warranties of the Master Servicer or the Depositor, as
the case may be. Unless otherwise specified in the related Prospectus
Supplement, this obligation to cure, purchase or substitute constitutes the sole
remedy available to the Securityholders or the Trustee for omission of, or a
material defect in, a constituent document.
 
     The Trustee will be authorized to appoint a custodian pursuant to a
custodial agreement to maintain possession of and, if applicable, to review the
documents relating to the Loans as agent of the Trustee.
 
     The Master Servicer will make certain representations and warranties
regarding its authority to enter into, and its ability to perform its
obligations under, the Agreement. Upon a breach of any such representation of
the Master Servicer which materially and adversely affects the interests of the
Securityholders in a Loan, the Master Servicer will be obligated either to cure
the breach in all material respects or to purchase (at the Purchase Price) or if
so specified in the related Prospectus Supplement, replace the Loan. Unless
otherwise specified in the related Prospectus Supplement, this obligation to
cure, purchase or substitute constitutes the sole remedy available to the
Securityholders or the Trustee for such a breach of representation by the Master
Servicer.
 
     Notwithstanding the foregoing provisions, with respect to a Trust Fund for
which a REMIC election is to be made, no purchase or substitution of a Loan will
be made if such purchase or substitution would result in a prohibited
transaction tax under the Code.
 
NO RECOURSE TO SELLERS, DEPOSITOR OR MASTER SERVICER
 
     As described above under ' -- Assignment of the Loans,' the Depositor will
cause the Loans comprising the related Trust Fund to be assigned to the Trustee,
without recourse. However, each Seller will be obligated to repurchase or
substitute for any Loan as to which certain representations and warranties are
breached or for failure to deliver certain documents relating to the Loans as
described herein under 'Assignment of the Loans' and 'Loan
Program -- Representations by Sellers; Repurchases.' In addition, the Master
Servicer and the Depositor will be obligated to purchase or substitute for any
Loan as to which certain representations and warranties are breached as
described herein under ' -- Assignment of the Loans.' These obligations to
purchase or substitute constitute the sole remedy available to the
Securityholders or the Trustee for a breach of any such representation or
failure to deliver a constituent document.
 
PAYMENTS ON LOANS; DEPOSITS TO SECURITY ACCOUNT
 
     The Master Servicer will establish and maintain or cause to be established
and maintained with respect to the related Trust Fund a separate account or
accounts for the collection of payments on the related Trust Fund Assets in the
Trust Fund (the 'Security Account') which, unless otherwise specified in the
related Prospectus
 
                                       49

Supplement, must be either (i) maintained with a depository institution the debt
obligations of which (or in the case of a depository institution that is the
principal subsidiary of a holding company, the obligations of which) are rated
in one of the two highest rating categories by the Rating Agency or Rating
Agencies that rated one or more classes of the related Series of Securities,
(ii) an account or accounts the deposits in which are fully insured by either
the Bank Insurance Fund (the 'BIF') of the FDIC or the Savings Association
Insurance Fund (as successor to the Federal Savings and Loan Insurance
Corporation ('SAIF')), (iii) an account or accounts the deposits in which are
insured by the BIF or SAIF (to the limits established by the FDIC), and the
uninsured deposits in which are otherwise secured such that, as evidenced by an
opinion of counsel, the Securityholders have a claim with respect to the funds
in the Security Account or a perfected first priority security interest against
any collateral securing such funds that is superior to the claims of any other
depositors or general creditors of the depository institution with which the
Security Account is maintained, or (iv) an account or accounts otherwise
acceptable to each Rating Agency. The collateral eligible to secure amounts in
the Security Account is limited to Permitted Investments. A Security Account may
be maintained as an interest bearing account or the funds held therein may be
invested pending each succeeding Distribution Date in Permitted Investments.
Unless otherwise specified in the related Prospectus Supplement, the Master
Servicer or its designee will be entitled to receive any such interest or other
income earned on funds in the Security Account as additional compensation and
will be obligated to deposit in the Security Account the amount of any loss
immediately as realized. The Security Account may be maintained with the Master
Servicer or with a depository institution that is an affiliate of the Master
Servicer, provided it meets the standards set forth above.
 
     The Master Servicer will deposit or cause to be deposited in the Security
Account for each Trust Fund, to the extent applicable and unless otherwise
specified in the related Prospectus Supplement and provided in the Agreement,
the following payments and collections received or advances made by or on behalf
of it subsequent to the Cut-off Date (other than payments due on or before the
Cut-off Date and exclusive of any amounts representing Retained Interest):
 
          (i) all payments on account of principal, including Principal
     Prepayments and, if specified in the related Prospectus Supplement, any
     applicable prepayment penalties, on the Loans;
 
          (ii) all payments on account of interest on the Loans, net of
     applicable servicing compensation;
 
          (iii) all proceeds (net of unreimbursed payments of property taxes,
     insurance premiums and similar items ('Insured Expenses') incurred, and
     unreimbursed Advances made, by the Master Servicer, if any) of the hazard
     insurance policies and any Primary Mortgage Insurance Policies, to the
     extent such proceeds are not applied to the restoration of the property or
     released to the Mortgagor in accordance with the Master Servicer's normal
     servicing procedures (collectively, 'Insurance Proceeds') and all other
     cash amounts (net of unreimbursed expenses incurred in connection with
     liquidation or foreclosure ('Liquidation Expenses') and unreimbursed
     Advances made, by the Master Servicer, if any) received and retained in
     connection with the liquidation of defaulted Loans, by foreclosure or
     otherwise ('Liquidation Proceeds'), together with any net proceeds received
     on a monthly basis with respect to any properties acquired on behalf of the
     Securityholders by foreclosure or deed in lieu of foreclosure;
 
          (iv) all proceeds of any Loan or property in respect thereof purchased
     by the Master Servicer, the Depositor or any Seller as described under
     'Loan Program -- Representations by Sellers; Repurchases' or
     ' -- Assignment of Trust Fund Assets' above and all proceeds of any Loan
     repurchased as described under ' -- Termination; Optional Termination'
     below;
 
          (v) all payments required to be deposited in the Security Account with
     respect to any deductible clause in any blanket insurance policy described
     under ' -- Hazard Insurance' below;
 
          (vi) any amount required to be deposited by the Master Servicer in
     connection with losses realized on investments for the benefit of the
     Master Servicer of funds held in the Security Account and, to the extent
     specified in the related Prospectus Supplement, any payments required to be
     made by the Master Servicer in connection with prepayment interest
     shortfalls; and
 
          (vii) all other amounts required to be deposited in the Security
     Account pursuant to the Agreement.
 
     The Master Servicer (or the Depositor, as applicable) may from time to time
direct the institution that maintains the Security Account to withdraw funds
from the Security Account for the following purposes:
 
                                       50
 

<PAGE>
<PAGE>

          (i) to pay to the Master Servicer the servicing fees described in the
     related Prospectus Supplement, the master servicing fees (subject to
     reduction) and, as additional servicing compensation, earnings on or
     investment income with respect to funds in the amounts in the Security
     Account credited thereto;
 
          (ii) to reimburse the Master Servicer for Advances, such right of
     reimbursement with respect to any Loan being limited to amounts received
     that represent late recoveries of payments of principal and/or interest on
     such Loan (or Insurance Proceeds or Liquidation Proceeds with respect
     thereto) with respect to which such Advance was made;
 
          (iii) to reimburse the Master Servicer for any Advances previously
     made which the Master Servicer has determined to be nonrecoverable;
 
          (iv) to reimburse the Master Servicer from Insurance Proceeds for
     expenses incurred by the Master Servicer and covered by the related
     insurance policies;
 
          (v) to reimburse the Master Servicer for unpaid master servicing fees
     and unreimbursed out-of-pocket costs and expenses incurred by the Master
     Servicer in the performance of its servicing obligations, such right of
     reimbursement being limited to amounts received representing late
     recoveries of the payments for which such advances were made;
 
          (vi) to pay to the Master Servicer, with respect to each 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 principal balance of such repurchased
     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 Security Account and
     not required to be deposited therein; and
 
          (ix) to clear and terminate the Security Account upon termination of
     the Agreement.
 
     In addition, unless otherwise specified in the related Prospectus
Supplement, on or prior to the business day immediately preceding each
Distribution Date, the Master Servicer shall withdraw from the Security Account
the amount of Available Funds, to the extent on deposit, for deposit in an
account maintained by the Trustee for the related Series of Securities.
 
PRE-FUNDING ACCOUNT
 
     If so provided in the related Prospectus Supplement, the Master Servicer
will establish and maintain a Pre-Funding Account, in the name of the related
Trustee on behalf of the related Securityholders, into which the Depositor will
deposit cash in an amount equal to the Pre-Funded Amount on the related Closing
Date. The Pre-Funding Account will be maintained with the Trustee for the
related Series of Securities and is designed solely to hold funds to be applied
by such Trustee during the Funding Period to pay to the Depositor the purchase
price for Subsequent Loans. Monies on deposit in the Pre-Funding Account will
not be available to cover losses on or in respect of the related Loans. The
Pre-Funded Amount will not exceed 50% of the initial aggregate principal amount
of the Certificates and Notes of the related Series. The Pre-Funded Amount will
be used by the related Trustee to purchase Subsequent Loans from the Depositor
from time to time during the Funding Period. The Funding Period, if any, for a
Trust Fund will begin on the related Closing Date and will end on the date
specified in the related Prospectus Supplement, which in no event will be later
than the date that is one year after the related Closing Date. Monies on deposit
in the Pre-Funding Account may be invested in Permitted Investments under the
circumstances and in the manner described in the related Agreement. Earnings on
investment of funds in the Pre-Funding Account will be deposited into the
related Security Account or such other trust account as is specified in the
related Prospectus Supplement and losses will be charged against the funds on
deposit in the Pre-Funding Account. Any amounts remaining in the Pre-Funding
Account at the end of the Funding Period will be distributed to the related
Securityholders in the manner and priority specified in the related Prospectus
Supplement, as a prepayment of principal of the related Securities.
 
     In addition, if so provided in the related Prospectus Supplement, on the
related Closing Date the Depositor will deposit in an account (the 'Capitalized
Interest Account') cash in such amount as is necessary to cover shortfalls in
interest on the related Series of Securities that may arise as a result of
utilization of the Pre-Funding Account as described above. The Capitalized
Interest Account shall be maintained with the Trustee for the
 
                                       51
 

<PAGE>
<PAGE>

related Series of Securities and is designed solely to cover the above-mentioned
interest shortfalls. Monies on deposit in the Capitalized Interest Account will
not be available to cover losses on or in respect of the related Loans. To the
extent that the entire amount on deposit in the Capitalized Interest Account has
not been applied to cover shortfalls in interest on the related Series of
Securities by the end of the Funding Period, any amounts remaining in the
Capitalized Interest Account will be paid to the Depositor.
 
SUB-SERVICING BY SELLERS
 
     Each Seller of a Loan or any other servicing entity may act as the
Sub-Servicer for such Loan pursuant to an agreement (each, a 'Sub-Servicing
Agreement'), which will not contain any terms inconsistent with the related
Agreement. While each Sub-Servicing Agreement will be a contract solely between
the Master Servicer and the Sub-Servicer, the Agreement pursuant to which a
Series of Securities is issued will provide that, if for any reason the Master
Servicer for such Series of Securities is no longer the Master Servicer of the
related Loans, the Trustee or any successor Master Servicer must recognize the
Sub-Servicer's rights and obligations under such Sub-Servicing Agreement.
Notwithstanding any such subservicing arrangement, unless otherwise provided in
the related Prospectus Supplement, the Master Servicer will remain liable for
its servicing duties and obligations under the Master Servicing Agreement as if
the Master Servicer alone were servicing the Loans.
 
COLLECTION PROCEDURES
 
     The Master Servicer, directly or through one or more Sub-Servicers, will
make reasonable efforts to collect all payments called for under the Loans and
will, consistent with each Agreement and any Pool Insurance Policy, Primary
Mortgage Insurance Policy, FHA Insurance, VA Guaranty, bankruptcy bond or
alternative arrangements, follow such collection procedures as are customary
with respect to loans that are comparable to the Loans. Consistent with the
above, the Master Servicer may, in its discretion, (i) waive any assumption fee,
late payment or other charge in connection with a Loan and (ii) to the extent
not inconsistent with the coverage of such Loan by a Pool Insurance Policy,
Primary Mortgage Insurance Policy, FHA Insurance, VA Guaranty, bankruptcy bond
or alternative arrangements, if applicable, arrange with a borrower a schedule
for the liquidation of delinquencies running for no more than 125 days after the
applicable due date for each payment. To the extent the Master Servicer is
obligated to make or cause to be made Advances, such obligation will remain
during any period of such an arrangement.
 
     In any case in which property securing a Loan has been, or is about to be,
conveyed by the mortgagor or obligor, the Master Servicer will, to the extent it
has knowledge of such conveyance or proposed conveyance, exercise or cause to be
exercised its rights to accelerate the maturity of such Loan under any
due-on-sale clause applicable thereto, but only if the exercise of such rights
is permitted by applicable law and will not impair or threaten to impair any
recovery under any Primary Mortgage Insurance Policy. If these conditions are
not met or if the Master Servicer reasonably believes it is unable under
applicable law to enforce such due-on-sale clause or if such Loan is a mortgage
loan insured by the FHA or partially guaranteed by the VA, the Master Servicer
will enter into or cause to be entered into an assumption and modification
agreement with the person to whom such property has been or is about to be
conveyed, pursuant to which such person becomes liable for repayment of the Loan
and, to the extent permitted by applicable law, the mortgagor remains liable
thereon. Any fee collected by or on behalf of the Master Servicer for entering
into an assumption agreement will be retained by or on behalf of the Master
Servicer as additional servicing compensation. See 'Certain Legal Aspects of the
Loans -- Due-on-Sale Clauses'. In connection with any such assumption, the terms
of the related Loan may not be changed.
 
     With respect to Cooperative Loans, any prospective purchaser will generally
have to obtain the approval of the board of directors of the relevant
Cooperative before purchasing the shares and acquiring rights under the related
proprietary lease or occupancy agreement. See 'Certain Legal Aspects of the
Loans'. This approval is usually based on the purchaser's income and net worth
and numerous other factors. Although the Cooperative's approval is unlikely to
be unreasonably withheld or delayed, the necessity of acquiring such approval
could limit the number of potential purchasers for those shares and otherwise
limit the Trust Fund's ability to sell and realize the value of those shares.
 
     In general a 'tenant-stockholder' (as defined in Code Section 216(b)(2) of
a corporation that qualifies as a 'cooperative housing corporation' within the
meaning of Code Section 216(b)(1) is allowed a deduction for
 
                                       52
 

<PAGE>
<PAGE>

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.
 
HAZARD INSURANCE
 
     Except as otherwise specified in the related Prospectus Supplement, the
Master Servicer will require the mortgagor or obligor on each Loan to maintain a
hazard insurance policy providing for no less than the coverage of the standard
form of fire insurance policy with extended coverage customary for the type of
Property in the state in which such Property is located. Such coverage will be
in an amount that is at least equal to the lesser of (i) the maximum insurable
value of the improvements securing such Loan or (ii) the greater of (y) the
outstanding principal balance of the Loan and (z) an amount such that the
proceeds of such policy shall be sufficient to prevent the mortgagor and/or the
mortgagee from becoming a co-insurer. All amounts collected by the Master
Servicer under any hazard policy (except for amounts to be applied to the
restoration or repair of the Property or released to the mortgagor or obligor in
accordance with the Master Servicer's normal servicing procedures) will be
deposited in the related Security Account. In the event that the Master Servicer
maintains a blanket policy insuring against hazard losses on all the Loans
comprising part of a Trust Fund, it will conclusively be deemed to have
satisfied its obligation relating to the maintenance of hazard insurance. Such
blanket policy may contain a deductible clause, in which case the Master
Servicer will be required to deposit from its own funds into the related
Security Account the amounts which would have been deposited therein but for
such clause.
 
     In general, the standard form of fire and extended coverage policy covers
physical damage to or destruction of the improvements securing a Loan by fire,
lightning, explosion, smoke, windstorm and hail, riot, strike and civil
commotion, subject to the conditions and exclusions particularized in each
policy. Although the policies relating to the Loans may have been underwritten
by different insurers under different state laws in accordance with different
applicable forms and therefore may not contain identical terms and conditions,
the basic terms thereof are dictated by respective state laws, and most such
policies typically do not cover any physical damage resulting from the
following: war, revolution, governmental actions, floods and other water-related
causes, earth movement (including earthquakes, landslides and mud flows),
nuclear reactions, wet or dry rot, vermin, rodents, insects or domestic animals,
theft and, in certain cases, vandalism and hurricanes. The foregoing list is
merely indicative of certain kinds of uninsured risks and is not intended to be
all inclusive. If the Property securing a Loan is located in a federally
designated special flood area at the time of origination, the Master Servicer
will require the mortgagor or obligor to obtain and maintain flood insurance.
 
     The hazard insurance policies covering properties securing the Loans
typically contain a clause which in effect requires the insured at all time to
carry insurance of a specified percentage of a specified percentage (generally
80% to 90%) of the full replacement value of the insured property in order to
recover the full amount of any partial loss. If the insured's coverage falls
below this specified percentage, then the insurer's liability in the event of
partial loss will not exceed the larger of (i) the actual cash value (generally
defined as replacement cost at the time and place of loss, less physical
depreciation) of the improvements damaged or destroyed or (ii) such proportion
of the loss as the amount of insurance carried bears to the specified percentage
of the full replacement cost of such improvements. Since the amount of hazard
insurance the Master Servicer may cause to be maintained on the improvements
securing the Loans declines as the principal balances owing thereon decrease,
and since improved real estate generally has appreciated in value over time in
the past, the effect of
 
                                       53
 

<PAGE>
<PAGE>

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'.
 
     The Master Servicer will not require that a standard hazard or flood
insurance policy be maintained on the cooperative dwelling relating to any
Cooperative Loan. Generally, the Cooperative itself is responsible for
maintenance of hazard insurance for the property owned by the Cooperative and
the tenant-stockholders of that Cooperative do not maintain individual hazard
insurance policies. To the extent, however, that a Cooperative and the related
borrower on a Cooperative Loan do not maintain such insurance or do not maintain
adequate coverage or any insurance proceeds are not applied to the restoration
of damaged property, any damage to such borrower's cooperative dwelling or such
Cooperative's building could significantly reduce the value of the collateral
securing such Cooperative Loan to the extent not covered by other credit
support.
 
     If the Property securing a defaulted Loan is damaged and proceeds, if any,
from the related hazard insurance policy are insufficient to restore the damaged
Property, the Master Servicer is not required to expend its own funds to restore
the damaged Property unless it determines (i) that such restoration will
increase the proceeds to Securityholders on liquidation of the Loan after
reimbursement of the Master Servicer for its expenses and (ii) that such
expenses will be recoverable by it from related Insurance Proceeds or
Liquidation Proceeds.
 
     If recovery on a defaulted Loan under any related Insurance Policy is not
available for the reasons set forth in the preceding paragraph, or if the
defaulted Loan is not covered by an Insurance Policy, the Master Servicer will
be obligated to follow or cause to be followed such normal practices and
procedures as it deems necessary or advisable to realize upon the defaulted
Loan. If the proceeds of any liquidation of the Property securing the defaulted
Loan are less than the principal balance of such Loan plus interest accrued
thereon that is payable to Securityholders, the Trust Fund will realize a loss
in the amount of such difference plus the aggregate of expenses incurred by the
Master Servicer in connection with such proceedings and which are reimbursable
under the Agreement. In the unlikely event that any such proceedings result in a
total recovery which is, after reimbursement to the Master Servicer of its
expenses, in excess of the principal balance of such Loan plus interest accrued
thereon that is payable to Securityholders, the Master Servicer will be entitled
to withdraw or retain from the Security Account amounts representing its normal
servicing compensation with respect to such Loan and, unless otherwise specified
in the related Prospectus Supplement, amounts representing the balance of such
excess, exclusive of any amount required by law to be forwarded to the related
borrower, as additional servicing compensation.
 
     If the Master Servicer or its designee recovers Insurance Proceeds which,
when added to any related Liquidation Proceeds and after deduction of certain
expenses reimbursable to the Master Servicer, exceed the principal balance of
such Loan plus interest accrued thereon that is payable to Securityholders, the
Master Servicer will be entitled to withdraw or retain from the Security Account
amounts representing its normal servicing compensation with respect to such
Loan. In the event that the Master Servicer has expended its own funds to
restore the damaged Property and such funds have not been reimbursed under the
related hazard insurance policy, it will be entitled to withdraw from the
Security Account out of related Liquidation Proceeds or Insurance Proceeds an
amount equal to such expenses incurred by it, in which event the Trust Fund may
realize a loss up to the amount so charged. Since Insurance Proceeds cannot
exceed deficiency claims and certain expenses incurred by the Master Servicer,
no such payment or recovery will result in a recovery to the Trust Fund which
exceeds the principal balance of the defaulted Loan together with accrued
interest thereon. See 'Credit Enhancement'.
 
     The proceeds from any liquidation of a Loan will be applied in the
following order of priority: first, to reimburse the Master Servicer for any
unreimbursed expenses incurred by it to restore the related Property and any
unreimbursed servicing compensation payable to the Master Servicer with respect
to such Loan; second, to reimburse the Master Servicer for any unreimbursed
Advances with respect to such Loan; third, to accrued and unpaid interest (to
the extent no Advance has been made for such amount) on such Loan; and fourth,
as a recovery of principal of such Loan.

REALIZATION UPON DEFAULTED LOANS
 
     Primary Mortgage Insurance Policies.  If so specified in the related
Prospectus Supplement, the Master Servicer will maintain or cause to be
maintained, as the case may be, in full force and effect, a Primary Mortgage
Insurance Policy with regard to each Loan for which such coverage is required.
Primary Mortgage Insurance Policies reimburse certain losses sustained by reason
of defaults in payments by borrowers. The Master Servicer will not cancel or
refuse to renew any such Primary Mortgage Insurance Policy in effect at the time
of the initial issuance of a Series of Securities that is required to be kept in
force under the applicable Agreement unless the replacement Primary Mortgage
Insurance Policy for such cancelled or nonrenewed policy is maintained with an
insurer whose claims-paying ability is sufficient to maintain the current rating
of the classes of Securities of such Series that have been rated.
 
     FHA Insurance; VA Guaranties.  Loans designated in the related Prospectus
Supplement as insured by the FHA will be insured by the FHA as authorized under
the United States Housing Act of 1937, as amended. In addition to the Title I
Program of the FHA, see 'Certain Legal Aspects of the Loans -- Title I Program',
certain Loans will be insured under various FHA programs including the standard
FHA 203(b) program to finance the acquisition of one- to four-family housing
units and the FHA 245 graduated payment mortgage program. These programs
generally limit the principal amount and interest rates of the mortgage loans
insured. Loans insured by FHA generally require a minimum down payment of
approximately 5% of the original principal amount of the loan. No FHA-insured
Loans relating to a Series may have an interest rate or original principal
amount exceeding the applicable FHA limits at the time of origination of such
loan.
 
     Loans designated in the related Prospectus Supplement as guaranteed by the
VA will be partially guaranteed by the VA under the Serviceman's Readjustment
Act of 1944, as amended (a 'VA Guaranty'). The Serviceman's Readjustment Act of
1944, as amended, permits a veteran (or in certain instances the spouse of a
veteran) to obtain a mortgage loan guaranty by the VA covering mortgage
financing of the purchase of a one- to four-family dwelling unit at interest
rates permitted by the VA. The program has no mortgage loan limits, requires no
down payment from the purchaser and permits the guaranty of mortgage loans of up
to 30 years' duration. However, no Loan guaranteed by the VA will have an
original principal amount greater than five times the partial VA guaranty for
such Loan. The maximum guaranty that may be issued by the VA under a VA
guaranteed mortgage loan depends upon the original principal amount of the
mortgage loan, as further described in 38 United States Code Section 1803(a), as
amended.
 
SERVICING AND OTHER COMPENSATION AND PAYMENT OF EXPENSES
 
     The principal servicing compensation to be paid to the Master Servicer in
respect of its master servicing activities for each Series of Securities will be
equal to the percentage per annum described in the related Prospectus Supplement
(which may vary under certain circumstances) of the outstanding principal
balance of each Loan, and such compensation will be retained by it from
collections of interest on such Loan in the related Trust Fund (the 'Master
Servicing Fee'). As compensation for its servicing duties, a Sub-Servicer or, if
there is no Sub-Servicer, the Master Servicer will be entitled to a monthly
servicing fee as described in the related Prospectus Supplement. In addition,
the Master Servicer or Sub-Servicer will retain all prepayment charges,
assumption fees and late payment charges, to the extent collected from
borrowers, and any benefit that may accrue as a result of the investment of
funds in the applicable Security Account (unless otherwise specified in the
related Prospectus Supplement).
 
     The Master Servicer will 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 expenses incurred in enforcing the obligations of Sub-Servicers and Sellers
under certain limited circumstances.
 
EVIDENCE AS TO COMPLIANCE
 
     Each Agreement will provide that on or before a specified date in each
year, a firm of independent public accountants will furnish a statement to the
Trustee to the effect that, on the basis of the examination by such
 
                                       55
 

<PAGE>
<PAGE>

firm conducted substantially in compliance with the Uniform Single Attestation
Program for Mortgage Bankers or the Audit Program for Mortgages serviced for
FHLMC, the servicing by or on behalf of the Master Servicer of mortgage loans or
private asset backed securities, or under pooling and servicing agreements
substantially similar to each other (including the related Agreement) was
conducted in compliance with such agreements except for any significant
exceptions or errors in records that, in the opinion of the firm, the Audit
Program for Mortgages serviced for FHLMC, or the Uniform Single Attestation
Program for Mortgage Bankers, it is required to report. In rendering its
statement such firm may rely, as to matters relating to the direct servicing of
Loans by Sub-Servicers, upon comparable statements for examinations conducted
substantially in compliance with the Uniform Single Attestation Program for
Mortgage Bankers or the Audit Program for Mortgages serviced for FHLMC (rendered
within one year of such statement) of firms of independent public accountants
with respect to the related Sub-Servicer.
 
     Each Agreement will also provide for delivery to the Trustee, on or before
a specified date in each year, of an annual statement signed by two officers of
the Master Servicer to the effect that the Master Servicer has fulfilled its
obligations under the Agreement throughout the preceding year.
 
     Copies of the annual accountants' statement and the statement of officers
of the Master Servicer may be obtained by Securityholders of the related Series
without charge upon written request to the Master Servicer at the address set
forth in the related Prospectus Supplement.
 
CERTAIN MATTERS REGARDING THE MASTER SERVICER AND THE DEPOSITOR
 
     The Master Servicer under each Pooling and Servicing Agreement or Master
Servicing Agreement, as applicable, will be named in the related Prospectus
Supplement. The entity serving as Master Servicer may have normal business
relationships with the Depositor or the Depositor's affiliates.
 
     Each Agreement will provide that the Master Servicer may not resign from
its obligations and duties under the Agreement except upon a determination that
its duties thereunder are no longer permissible under applicable law. The Master
Servicer may, however, be removed from its obligations and duties as set forth
in the Agreement. No such resignation will become effective until the Trustee or
a successor servicer has assumed the Master Servicer's obligations and duties
under the Agreement.
 
     Each Agreement will further provide that neither the Master Servicer, the
Depositor nor any director, officer, employee, or agent of the Master Servicer
or the Depositor will be under any liability to the related Trust Fund or
Securityholders for any action taken or for refraining from the taking of any
action in good faith pursuant to the Agreement, or for errors in judgment;
provided, however, that neither the Master Servicer, the Depositor nor any such
person will be protected against any liability which would otherwise be imposed
by reason of wilful misfeasance, bad faith or gross negligence in the
performance of duties thereunder or by reason of reckless disregard of
obligations and duties thereunder. Each Agreement will further provide that the
Master Servicer, the Depositor and any director, officer, employee or agent of
the Master Servicer or the Depositor will be entitled to indemnification by the
related Trust Fund and will be held harmless against any loss, liability or
expense incurred in connection with any legal action relating to the Agreement
or the Securities, other than any loss, liability or expense related to any
specific Loan or Loans (except any such loss, liability or expense otherwise
reimbursable pursuant to the Agreement) and any loss, liability or expense
incurred by reason of willful misfeasance, bad faith or gross negligence in the
performance of duties thereunder or by reason of reckless disregard of
obligations and duties thereunder. In addition, each Agreement will provide that
neither the Master Servicer nor the Depositor will be under any obligation to
appear in, prosecute or defend any legal action which is not incidental to its
respective responsibilities under the Agreement and which in its opinion may
involve it in any expense or liability. The Master Servicer or the Depositor
may, however, in its discretion undertake any such action which it may deem
necessary or desirable with respect to the Agreement and the rights and duties
of the parties thereto and the interests of the Securityholders thereunder. In
such event, the legal expenses and costs of such action and any liability
resulting therefrom will be expenses, costs and liabilities of the Trust Fund
and the Master Servicer or the Depositor, as the case may be, will be entitled
to be reimbursed therefor out of funds otherwise distributable to
Securityholders.
 
     Except as otherwise specified in the related Prospectus Supplement, any
person into which the Master Servicer may be merged or consolidated, or any
person resulting from any merger or consolidation to which the Master Servicer
is a party, or any person succeeding to the business of the Master Servicer,
will be the successor
 
                                       56
 

<PAGE>
<PAGE>

of the Master Servicer under each Agreement, provided that such person is
qualified to sell mortgage loans to, and service mortgage loans on behalf of,
FNMA or FHLMC and further provided that such merger, consolidation or succession
does not adversely affect the then current rating or ratings of the class or
classes of Securities of such Series that have been rated.
 
EVENTS OF DEFAULT; RIGHTS UPON EVENT OF DEFAULT
 
     Pooling and Servicing Agreement; Master Servicing Agreement.  Except as
otherwise specified in the related Prospectus Supplement, Events of Default
under each Agreement will consist of (i) any failure by the Master Servicer to
distribute or cause to be distributed to Securityholders of any class any
required payment (other than an Advance) which continues unremedied for five
days after the giving of written notice of such failure to the Master Servicer
by the Trustee or the Depositor, or to the Master Servicer, the Depositor and
the Trustee by the holders of Securities of such class evidencing not less than
25% of the total distributions allocated to such class ('Percentage Interests');
(ii) any failure by the Master Servicer 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 thirty
days after the giving of written notice of such failure to the Master Servicer
by the Trustee or the Depositor, or to the Master Servicer, the Depositor and
the Trustee by the holders of Securities of any class evidencing not less than
25% of the aggregate Percentage Interests constituting such class; and (iv)
certain events of insolvency, readjustment of debt, marshalling of assets and
liabilities or similar proceeding and certain actions by or on behalf of the
Master Servicer indicating its insolvency, reorganization or inability to pay
its obligations.
 
     If specified in the related Prospectus Supplement, the Agreement will
permit the Trustee to sell the Trust Fund Assets and the other assets of the
Trust Fund described under 'Credit Enhancement' herein in the event that
payments in respect thereto are insufficient to make payments required in the
Agreement. The assets of the Trust Fund will be sold only under the
circumstances and in the manner specified in the related Prospectus Supplement.
 
     Unless otherwise provided in the related Prospectus Supplement, so long as
an Event of Default under an Agreement remains unremedied, the Depositor or the
Trustee may, and at the direction of holders of Securities of any class
evidencing not less than 25% of the aggregate Percentage Interests constituting
such class and under such other circumstances as may be specified in such
Agreement, the Trustee shall terminate all of the rights and obligations of the
Master Servicer under the Agreement relating to such Trust Fund and in and to
the related Trust Fund Assets, whereupon the Trustee will succeed to all of the
responsibilities, duties and liabilities of the Master Servicer under the
Agreement, including, if specified in the related Prospectus Supplement, the
obligation to make Advances, and will be entitled to similar compensation
arrangements. In the event that the Trustee is unwilling or unable so to act, it
may appoint, or petition a court of competent jurisdiction for the appointment
of, a mortgage loan servicing institution with a net worth of a least
$10,000,000 to act as successor to the Master Servicer under the Agreement.
Pending such appointment, the Trustee is obligated to act in such capacity. The
Trustee and any such successor may agree upon the servicing compensation to be
paid, which in no event may be greater than the compensation payable to the
Master Servicer under the Agreement.
 
     Unless otherwise provided in the related Prospectus Supplement, no
Securityholder, solely by virtue of such holder's status as a Securityholder,
will have any right under any Agreement to institute any proceeding with respect
to such Agreement, unless such holder previously has given to the Trustee
written notice of default and unless the holders of Securities of any class of
such Series evidencing not less than 25% of the aggregate Percentage Interests
constituting such class have made written request upon the Trustee to institute
such proceeding in its own name as Trustee thereunder and have offered to the
Trustee reasonable indemnity, and the Trustee for 60 days has neglected or
refused to institute any such proceeding.
 
     Indenture.  Except as otherwise specified in the related Prospectus
Supplement, Events of Default under the Indenture for each Series of Notes
include: (i) a default in the payment of any principal of or interest on any
Note of such Series which continues unremedied for five days after the giving of
written notice of such default is given as specified in the related Prospectus
Supplement; (ii) failure to perform in any material respect any other covenant
of the Depositor or the Trust Fund in the Indenture which continues for a period
of thirty (30) days after notice thereof is given in accordance with the
procedures described in the related Prospectus Supplement; (iii) certain events
of bankruptcy, insolvency, receivership or liquidation of the Depositor or the
 
                                       57
 

<PAGE>
<PAGE>

Trust Fund; or (iv) any other Event of Default provided with respect to Notes of
that Series including but not limited to certain defaults on the part of the
issuer, if any, of a credit enhancement instrument supporting such Notes.
 
     If an Event of Default with respect to the Notes of any Series at the time
outstanding occurs and is continuing, either the Trustee or the holders of a
majority of the then aggregate outstanding amount of the Notes of such Series
may declare the principal amount (or, if the Notes of that Series have an
interest rate of 0%, such portion of the principal amount as may be specified in
the terms of that Series, as provided in the related Prospectus Supplement) of
all the Notes of such Series to be due and payable immediately. Such declaration
may, under certain circumstances, be rescinded and annulled by the holders of
more than 50% of the Percentage Interests of the Notes of such Series.
 
     If, following an Event of Default with respect to any Series of Notes, the
Notes of such Series have been declared to be due and payable, the Trustee may,
in its discretion, notwithstanding such acceleration, elect to maintain
possession of the collateral securing the Notes of such Series and to continue
to apply distributions on such collateral as if there had been no declaration of
acceleration if such collateral continues to provide sufficient funds for the
payment of principal of and interest on the Notes of such Series as they would
have become due if there had not been such a declaration. In addition, the
Trustee may not sell or otherwise liquidate the collateral securing the Notes of
a Series following an Event of Default, other than a default in the payment of
any principal or interest on any Note of such Series for five days or more,
unless (a) the holders of 100% of the Percentage Interests of the Notes of such
Series consent to such sale, (b) the proceeds of such sale or liquidation are
sufficient to pay in full the principal of and accrued interest, due and unpaid,
on the outstanding Notes of such Series at the date of such sale or (c) the
Trustee determines that such collateral would not be sufficient on an ongoing
basis to make all payments on such Notes as such payments would have become due
if such Notes had not been declared due and payable, and the Trustee obtains the
consent of the holders of 66 2/3% of the Percentage Interests of the Notes of
such Series.
 
     In the event that the Trustee liquidates the collateral in connection with
an Event of Default involving a default for five days or more in the payment of
principal of or interest on the Notes of a Series, the Indenture provides that
the Trustee will have a prior lien on the proceeds of any such liquidation for
unpaid fees and expenses. As a result, upon the occurrence of such an Event of
Default, the amount available for distribution to the Noteholders would be less
than would otherwise be the case. However, the Trustee may not institute a
proceeding for the enforcement of its lien except in connection with a
proceeding for the enforcement of the lien of the Indenture for the benefit of
the Noteholders after the occurrence of such an Event of Default.
 
     Except as otherwise specified in the related Prospectus Supplement, in the
event the principal of the Notes of a Series is declared due and payable, as
described above, the holders of any such Notes issued at a discount from par may
be entitled to receive no more than an amount equal to the unpaid principal
amount thereof less the amount of such discount which is unamortized.
 
     Subject to the provisions of the Indenture relating to the duties of the
Trustee, in case an Event of Default shall occur and be continuing with respect
to a Series of Notes, the Trustee shall be under no obligation to exercise any
of the rights or powers under the Indenture at the request or direction of any
of the holders of Notes of such Series, unless such holders offered to the
Trustee security or indemnity satisfactory to it against the costs, expenses and
liabilities which might be incurred by it in complying with such request or
direction. Subject to such provisions for indemnification and certain
limitations contained in the Indenture, the holders of a majority of the then
aggregate outstanding amount of the Notes of such Series shall have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee or exercising any trust or power conferred on the
Trustee with respect to the Notes of such Series, and the holders of a majority
of the then aggregate outstanding amount of the Notes of such Series may, in
certain cases, waive any default with respect thereto, except a default in the
payment of principal or interest or a default in respect of a covenant or
provision of the Indenture that cannot be modified without the waiver or consent
of all the holders of the outstanding Notes of such Series affected thereby.
 
AMENDMENT
 
     Except as otherwise specified in the related Prospectus Supplement, each
Agreement may be amended by the Depositor, the Master Servicer and the Trustee,
without the consent of any of the Securityholders, (i) to cure
 
                                       58
 

<PAGE>
<PAGE>

any ambiguity; (ii) to correct or supplement any provision therein which may be
defective or inconsistent with any other provision therein; or (iii) to make any
other revisions with respect to matters or questions arising under the Agreement
which are not inconsistent with the provisions thereof, provided that such
action will not adversely affect in any material respect the interests of any
Securityholder. An amendment will be deemed not to adversely affect in any
material respect the interests of the Securityholders if the person requesting
such amendment obtains a letter from each Rating Agency requested to rate the
class or classes of Securities of such Series stating that such amendment will
not result in the downgrading or withdrawal of the respective ratings then
assigned to such Securities. In addition, to the extent provided in the related
Agreement, an Agreement may be amended without the consent of any of the
Securityholders, to change the manner in which the Security Account is
maintained, provided that any such change does not adversely affect the then
current rating on the class or classes of Securities 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. Except as otherwise specified in the related
Prospectus Supplement, each Agreement may also be amended by the Depositor, the
Master Servicer and the Trustee with consent of holders of Securities of such
Series evidencing not less than 66% of the aggregate Percentage Interests of
each class affected thereby for the purpose of adding any provisions to or
changing in an manner or eliminating any of the provisions of the Agreement or
of modifying in any manner the rights of the holders of the related Securities;
provided, however, that no such amendment may (i) reduce in any manner the
amount of or delay the timing of, payments received on Loans which are required
to be distributed on any Security without the consent of the holder of such
Security, or (ii) reduce the aforesaid percentage of Securities of any class the
holders of which are required to consent to any such amendment without the
consent of the holders of all Securities of such class covered by such Agreement
then outstanding. If a REMIC 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
 
     Pooling and Servicing Agreement; Trust Agreement.  Unless otherwise
specified in the related Agreement, the obligations created by each Pooling and
Servicing Agreement and Trust Agreement for each Series of Securities will
terminate upon the payment to the related Securityholders of all amounts held in
the Security Account or by the Master Servicer and required to be paid to them
pursuant to such Agreement following the later of (i) the final payment of or
other liquidation of the last of the Trust Fund Assets subject thereto or the
disposition of all property acquired upon foreclosure of any such Trust Fund
Assets remaining in the Trust Fund and (ii) the purchase by the Master Servicer
or, if REMIC treatment has been elected and if specified in the related
Prospectus Supplement, by the holder of the residual interest in the REMIC (see
'Federal Income Tax Consequences' below), from the related Trust Fund of all of
the remaining Trust Fund Assets and all property acquired in respect of such
Trust Fund Assets.
 
     Unless otherwise specified by the related Prospectus Supplement, any such
purchase of Trust Fund Assets and property acquired in respect of Trust Fund
Assets evidenced by a Series of Securities will be made at the option of the
Master Servicer, such other person or, if applicable, such holder of the REMIC
residual interest, at a price specified in the related Prospectus Supplement.
The exercise of such right will effect early retirement of the Securities of
that Series, but the right of the Master Servicer, such other person or, if
applicable, such holder of the REMIC residual interest, to so purchase is
subject to the principal balance of the related Trust Fund Assets being less
than the percentage specified in the related Prospectus Supplement of the
aggregate principal balance of the Trust Fund Assets at the Cut-off Date for the
Series. The foregoing is subject to the provision that if a REMIC election is
made with respect to a Trust Fund, any repurchase pursuant to clause (ii) above
will be made only in connection with a 'qualified liquidation' of the REMIC
within the meaning of Section 860F(g)(4) of the Code.
 
     Indenture.  The Indenture will be discharged with respect to a Series of
Notes (except with respect to certain continuing rights specified in the
Indenture) upon the delivery to the Trustee for cancellation of all the
 
                                       59
 

<PAGE>
<PAGE>

Notes of such Series or, with certain limitations, upon deposit with the Trustee
of funds sufficient for the payment in full of all of the Notes of such Series.
 
     In addition to such discharge with certain limitations, the Indenture will
provide that, if so specified with respect to the Notes of any Series, the
related Trust Fund will be discharged from any and all obligations in respect of
the Notes of such Series (except for certain obligations relating to temporary
Notes and exchange of Notes, to register the transfer of or exchange Notes of
such Series, to replace stolen, lost or mutilated Notes of such Series, to
maintain paying agencies and to hold monies for payment in trust) upon the
deposit with the Trustee, in trust, of money and/or direct obligations of or
obligations guaranteed by the United States of America which through the payment
of interest and principal in respect thereof in accordance with their terms will
provide money in an amount sufficient to pay the principal of and each
installment of interest on the Notes of such Series on the last scheduled
Distribution Date for such Notes and any installment of interest on such Notes
in accordance with the terms of the Indenture and the Notes of such Series. In
the event of any such defeasance and discharge of Notes of such Series, holders
of Notes of such Series would be able to look only to such money and/or direct
obligations for payment of principal and interest, if any, on their Notes until
maturity.
 
THE TRUSTEE
 
     The Trustee under each Agreement will be named in the applicable Prospectus
Supplement. The commercial bank or trust company serving as Trustee may have
normal banking relationships with the Depositor, the Master Servicer and any of
their respective affiliates.
 
                       CERTAIN LEGAL ASPECTS OF THE LOANS
 
     The following discussion contains summaries, which are general in nature,
of certain legal matters relating to the Loans. Because such legal aspects are
governed primarily by applicable state law (which laws may differ
substantially), the descriptions do not, except as expressly provided below,
reflect the laws of any particular state, nor encompass the laws of all states
in which the security for the Loans is situated. The descriptions are qualified
in their entirety by reference to the applicable federal laws and the
appropriate laws of the states in which Loans may be originated.
 
GENERAL
 
     The Loans for a Series may be secured by deeds of trust, mortgages,
security deeds or deeds to secure debt, depending upon the prevailing practice
in the state in which the property subject to the loan is located. Deeds of
trust are used almost exclusively in California instead of mortgages. A mortgage
creates a lien upon the real property encumbered by the mortgage, which lien is
generally not prior to the lien for real estate taxes and assessments. Priority
between mortgages depends on their terms and generally on the order of recording
with a state or county office. There are two parties to a mortgage, the
mortgagor, who is the borrower and owner of the mortgaged property, and the
mortgagee, who is the lender. Under the mortgage instrument, the mortgagor
delivers to the mortgagee a note or bond and the mortgage. Although a deed of
trust is similar to a mortgage, a deed of trust formally has three parties, the
borrower-property owner called the trustor (similar to a mortgagor), a lender
(similar to a mortgagee) called the beneficiary, and a third-party grantee
called the trustee. Under a deed of trust, the borrower grants the property,
irrevocably until the debt is paid, in trust, generally with a power of sale, to
the trustee to secure payment of the obligation. A security deed and a deed to
secure debt are special types of deeds which indicate on their face that they
are granted to secure an underlying debt. By executing a security deed or deed
to secure debt, the grantor conveys title to, as opposed to merely creating a
lien upon, the subject property to the grantee until such time as the underlying
debt is repaid. The trustee's authority under a deed of trust, the mortgagee's
authority under a mortgage and the grantee's authority under a security deed or
deed to secure debt are governed by law and, with respect to some deeds of
trust, the directions of the beneficiary.
 
     Cooperatives.  Certain of the Loans may be Cooperative Loans. The
Cooperative owns all the real property that comprises the project, including the
land, separate dwelling units and all common areas. The Cooperative is directly
responsible for project management and, in most cases, payment of real estate
taxes and hazard and liability insurance. If there is a blanket mortgage on the
Cooperative and/or underlying land, as is generally the case, the Cooperative,
as project mortgagor, is also responsible for meeting these mortgage
 
                                       60
 

<PAGE>
<PAGE>

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 proprietary lease and in the related
Cooperative shares. The lender takes possession of the share certificate and a
counterpart of the proprietary lease or occupancy agreement, and a financing
statement covering the proprietary lease or occupancy agreement and the
Cooperative shares is filed in the appropriate state and local offices to
perfect the lender's interest in its collateral. Subject to the limitations
discussed below, upon default of the tenant-stockholder, the lender may sue for
judgment on the promissory note, dispose of the collateral at a public or
private sale or otherwise proceed against the collateral or tenant-stockholder
as an individual as provided in the security agreement covering the assignment
of the proprietary lease or occupancy agreement and the pledge of Cooperative
shares.
 
FORECLOSURE
 
     Deed of Trust.  Foreclosure of a deed of trust is generally accomplished by
a non-judicial sale under a specific provision in the deed of trust which
authorizes the trustee to sell the property at public auction upon any default
by the borrower under the terms of the note or deed of trust. In certain states,
such foreclosure also may be accomplished by judicial action in the manner
provided for foreclosure of mortgages. In addition to any notice requirements
contained in a deed of trust, in some states (such as California), the trustee
must record a notice of default and send a copy to the borrower-trustor, to any
person who has recorded a request for a copy of any notice of default and notice
of sale, to any successor in interest to the borrower-trustor, to the
beneficiary of any junior deed of trust and to certain other persons. In some
states (including California), the borrower-trustor has the right to reinstate
the loan at any time following default until shortly before the trustee's sale.
In general, the borrower, or any other person having a junior encumbrance on the
real estate, may, during a statutorily prescribed reinstatement period, cure a
monetary default by paying the entire amount in arrears plus other designated
costs and expenses incurred in enforcing the obligation. Generally, state law
controls the amount of foreclosure expenses and costs, including attorney's
fees, which may be recovered by a lender. After the reinstatement period has
expired without the default having been cured, the borrower or junior lienholder
no longer has the right to reinstate the loan and must pay the loan in full to
prevent the scheduled foreclosure sale. If the deed of trust is not reinstated
within any applicable cure period, a notice of sale must be posted in a public
place and, in most states (including California), published for a specific
period of time in one or more newspapers. In addition, some state laws require
that a copy of the notice of sale be posted on the property and sent to all
parties having an interest of record in the real property. In California, the
entire process from recording a notice of default to a non-judicial sale usually
takes four to five months.
 
     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
 
                                       61
 

<PAGE>
<PAGE>

proceedings are often 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 some
states, mortgages may also be foreclosed by advertisement, pursuant to a power
of sale provided in the mortgage.
 
     Although foreclosure sales are typically public sales, frequently no third
party purchaser bids in excess of the lender's lien because of the difficulty of
determining the exact status of title to the property, the possible
deterioration of the property during the foreclosure proceedings and a
requirement that the purchaser pay for the property in cash or by cashier's
check. Thus the foreclosing lender often purchases the property from the trustee
or referee for an amount equal to the principal amount outstanding under the
loan, accrued and unpaid interest and the expenses of foreclosure in which event
the mortgagor's debt will be extinguished or the lender may purchase for a
lesser amount in order to preserve its right against a borrower to seek a
deficiency judgment in states where such judgment is available. Thereafter,
subject to the right of the borrower in some states to remain in possession
during the redemption period, the lender will assume the burden of ownership,
including obtaining hazard insurance and making such repairs at its own expense
as are necessary to render the property suitable for sale. The lender will
commonly obtain the services of a real estate broker and pay the broker's
commission in connection with the sale of the property. Depending upon market
conditions, the ultimate proceeds of the sale of the property may not equal the
lender's investment in the property. Any loss may be reduced by the receipt of
any mortgage guaranty insurance proceeds.
 
     Courts have imposed general equitable principles upon foreclosure, which
are generally designed to mitigate the legal consequences to the borrower of the
borrower's defaults under the loan documents. Some courts have been faced with
the issue of whether federal or state constitutional provisions reflecting due
process concerns for fair notice require that borrowers under deeds of trust
receive notice longer than that prescribed by statute. For the most part, these
cases have upheld the notice provisions as being reasonable or have found that
the sale by a trustee under a deed of trust does not involve sufficient state
action to afford constitutional protection to the borrower.
 
     When the beneficiary under a junior mortgage or deed of trust cures the
default and reinstates or redeems by paying the full amount of the senior
mortgage or deed of trust, the amount paid by the beneficiary so to cure or
redeem becomes a part of the indebtedness secured by the junior mortgage or deed
of trust. See 'Junior Mortgages; Rights of Senior Mortgagees' below.
 
     Cooperative Loans.  The Cooperative shares owned by the tenant-stockholder
and pledged to the lender are, in almost all cases, subject to restrictions on
transfer as set forth in the Cooperative's certificate of incorporation and
bylaws, as well as the proprietary lease or occupancy agreement, and may be
cancelled by the Cooperative for failure by the tenant-stockholder to pay rent
or other obligations or charges owed by such tenant-stockholder, including
mechanics' liens against the cooperative apartment building incurred by such
tenant-stockholder. The proprietary lease or occupancy agreement generally
permits the Cooperative to terminate such lease or agreement in the event an
obligor fails to make payments or defaults in the performance of covenants
required thereunder. Typically, the lender and the Cooperative enter into a
recognition agreement which establishes the rights and obligations of both
parties in the event of a default by the tenant-stockholder on its obligations
under the proprietary lease or occupancy agreement. A default by the
tenant-stockholder under the proprietary lease or occupancy agreement will
usually constitute a default under the security agreement between the lender and
the tenant-stockholder.
 
     The recognition agreement generally provides that, in the event that the
tenant-stockholder has defaulted under the proprietary lease or occupancy
agreement, the Cooperative will take no action to terminate such lease or
agreement until the lender has been provided with an opportunity to cure the
default. The recognition agreement typically provides that if the proprietary
lease or occupancy agreement is terminated, the Cooperative will recognize the
lender's lien against proceeds form the sale of the Cooperative apartment,
subject, however, to the Cooperative's right to sums due under such proprietary
lease or occupancy agreement. The total amount owed to the Cooperative by the
tenant-stockholder, which the lender generally cannot restrict and does not
monitor, could reduce the value of the collateral below the outstanding
principal balance of the Cooperative Loan and accrued and unpaid interest
thereon.
 
     Recognition agreements also provide that in the event of a foreclosure on a
Cooperative Loan, the lender must obtain the approval or consent of the
Cooperative as required by the proprietary lease before transferring
 
                                       62
 

<PAGE>
<PAGE>

the Cooperative shares or assigning the proprietary lease. Generally, the lender
is not limited in any rights it may have to dispossess the tenant-stockholders.
 
     In some states, foreclosure on the Cooperative shares is accomplished by a
sale in accordance with the provisions of Article 9 of the Uniform Commercial
Code (the 'UCC') and the security agreement relating to those shares. Article 9
of the UCC requires that a sale be conducted in a 'commercially reasonable'
manner. Whether a foreclosure sale has been conducted in a 'commercially
reasonable' manner will depend on the facts in each case. In determining
commercial reasonableness, a court will look to the notice given the debtor and
the method, manner, time, place and terms of the foreclosure. Generally, a sale
conducted according to the usual practice of banks selling similar collateral
will be considered reasonably conducted.
 
     Article 9 of the UCC provides that the proceeds of the sale will be applied
first to pay the costs and expenses of the sale and then to satisfy the
indebtedness secured by the lender's security interest. The recognition
agreement, however, generally provides that the lender's right to reimbursement
is subject to the right of the Cooperative to receive sums due under the
proprietary lease or occupancy agreement. If there are proceeds remaining, the
lender must account to the tenant-stockholder for the surplus. Conversely, if a
portion of the indebtedness remains unpaid, the tenant-stockholder is generally
responsible for the deficiency. See 'Anti-Deficiency Legislation and Other
Limitations on Lenders' below.
 
     In the case of foreclosure on a building which was converted from a rental
building to a building owned by a Cooperative under a non-eviction plan, some
states require that a purchaser at a foreclosure sale take the property subject
to rent control and rent stabilization laws which apply to certain tenants who
elected to remain in the building but who did not purchase shares in the
Cooperative when the building was so converted.
 
ENVIRONMENTAL RISKS
 
     Real property pledged as security to a lender may be subject to unforeseen
environmental risks. Under the laws of certain states, contamination of a
property may give rise to a lien on the property to assure the payment of the
costs of clean-up. In several states such a lien has priority over the lien of
an existing mortgage against such property. In addition, under the federal
Comprehensive Environmental Response, Compensation and Liability Act of 1980
('CERCLA'), the United States Environmental Protection Agency ('EPA') may impose
a lien on property where EPA has incurred clean-up costs. However, a CERCLA lien
is subordinate to pre-existing, perfected security interests.
 
     Under the laws of some states, and under CERCLA, it is conceivable that a
secured lender may be held liable as an 'owner' or 'operator' for the costs of
addressing releases or threatened releases of hazardous substances at a
Property, even though the environmental damage or threat was caused by a prior
or current owner or operator. CERCLA imposes liability for such costs on any and
all 'responsible parties,' including owners or operators. However, CERCLA
excludes from the definition of 'owner or operator' a secured creditor who holds
indicia of ownership primarily to protect its security interest (the 'secured
creditor exclusion') but without 'participating in the management' of the
Property. Thus, if a lender's activities begin to encroach on the actual
management of a contaminated facility or property, the lender may incur
liability as an 'owner or operator' under CERCLA. Similarly, if a lender
forecloses and takes title to a contaminated facility or property, the lender
may incur CERCLA liability in various circumstances, including, but not limited
to, when it holds the facility or property as an investment (including leasing
the facility or property to third party), or fails to market the property in a
timely fashion.
 
     Whether actions taken by a lender would constitute participation in the
management of a mortgaged property, or the business of a borrower, so as to
render the secured creditor exemption unavailable to a lender has been a matter
of judicial interpretation of the statutory language, and court decisions have
been inconsistent. In 1990, the Court of Appeals for the Eleventh Circuit
suggested that the mere capacity of the lender to influence a borrower's
decisions regarding disposal of hazardous substances was sufficient
participation in the management of the borrower's business to deny the
protection of the secured creditor exemption to the lender.
 
     This ambiguity appears to have been resolved by the enactment of the Asset
Conservation, Lender Liability and Deposit Insurance Protection Act of 1996,
which was signed into law by President Clinton on September 30, 1996. This
legislation provides that in order to be deemed to have participated in the
management of a mortgaged property, a lender must actually participate in the
operational affairs of the property or the borrower. The legislation also
provides that participation in the management of the property does not include
 
                                       63
 

<PAGE>
<PAGE>

'merely having the capacity to influence, or unexercised right to control'
operations. Rather, a lender will lose the protection of the secured creditor
exemption only if it exercises decision-making control over the borrower's
environmental compliance and hazardous substance handling and disposal
practices, or assumes day-to-day management of all operational functions of the
mortgaged property.
 
     If a lender is or becomes liable, it can bring an action for contribution
against any other 'responsible parties,' including a previous owner or operator,
who created the environmental hazard, but those persons or entities may be
bankrupt or otherwise judgment proof. The costs associated with environmental
cleanup may be substantial. It is conceivable that such costs arising from the
circumstances set forth above would result in a loss to Certificateholders.
 
     CERCLA does not apply to petroleum products, and the secured creditor
exclusion does not govern liability for cleanup costs under federal laws other
than CERCLA, in particular Subtitle I of the federal Resource Conservation and
Recovery Act ('RCRA'), which regulates underground petroleum storage tanks
(except heating oil tanks). The EPA has adopted a lender liability rule for
underground storage tanks under Subtitle I of RCRA. Under such rule, a holder of
a security interest in an underground storage tank or real property containing
an underground storage tank is not considered an operator of the underground
storage tank as long as petroleum is not added to, stored in or dispensed from
the tank. In addition, under the Asset Conservation, Lender Liability and
Deposit Insurance Protection Act of 1996, the protections accorded to lenders
under CERCLA are also accorded to the holders of security interests in
underground storage tanks. It should be noted, however, that liability for
cleanup of petroleum contamination may be governed by state law, which may not
provide for any specific protection for secured creditors, or alternatively, may
not impose liability on secured creditors at all.
 
     Except as otherwise specified in the related Prospectus Supplement, at the
time the Loans were originated, no environmental assessment or a very limited
environmental assessment of the Properties was conducted.
 
RIGHTS OF REDEMPTION
 
     In some states, after sale pursuant to a deed of trust or foreclosure of a
mortgage, the borrower and foreclosed junior lienors are given a statutory
period in which to redeem the property from the foreclosure sale. In certain
other states (including California), this right of redemption applies only to
sales following judicial foreclosure, and not to sales pursuant to a
non-judicial power of sale. In most states where the right of redemption is
available, statutory redemption may occur upon payment of the foreclosure
purchase price, accrued interest and taxes. In other states, redemption may be
authorized if the former borrower pays only a portion of the sums due. The
effect of a statutory right of redemption is to diminish the ability of the
lender to sell the foreclosed property. The exercise of a right of redemption
would defeat the title of any purchaser from the lender subsequent to
foreclosure or sale under a deed of trust. Consequently, the practical effect of
the redemption right is to force the lender to retain the property and pay the
expenses of ownership until the redemption period has run. In some states, there
is no right to redeem property after a trustee's sale under a deed of trust.
 
ANTI-DEFICIENCY LEGISLATION; BANKRUPTCY LAWS; TAX LIENS
 
     Certain states have imposed statutory and judicial restrictions that limit
the remedies of a beneficiary under a deed of trust or a mortgagee under a
mortgage. In some states, including California, statutes and case law limit the
right of the beneficiary or mortgagee to obtain a deficiency judgment against
borrowers financing the purchase of their residence or following sale under a
deed of trust or certain other foreclosure proceedings. A deficiency judgment is
a personal judgment against the borrower equal in most cases to the difference
between the amount due to the lender and the fair market value of the real
property at the time of the foreclosure sale. In certain states, including
California, if a lender simultaneously originates a loan secured by a senior
lien on a particular property and a loan secured by a junior lien on the same
property, such a lender as the holder of the junior lien may be precluded from
obtaining a deficiency judgment with respect to the excess of the aggregate
amount owed under both such loans over the proceeds of any sale under a deed of
trust or other foreclosure proceedings. As a result of these prohibitions, it is
anticipated that in most instances the Master Servicer will utilize the
non-judicial foreclosure remedy and will not seek deficiency judgments against
defaulting borrowers.
 
                                       64
 

<PAGE>
<PAGE>

     Some state statutes require the beneficiary or mortgagee to exhaust the
security afforded under a deed of trust or mortgage by foreclosure in an attempt
to satisfy the full debt before bringing a personal action against the borrower.
In certain other states, the lender has the option of bringing a personal action
against the borrower on the debt without first exhausting such security;
however, in some of these states, the lender, following judgment on such
personal action, may be deemed to have elected a remedy and may be precluded
from exercising remedies with respect to the security. Consequently, the
practical effect of the election requirement, when applicable, is that lenders
will usually proceed first against the security rather than bringing a personal
action against the borrower. In some states, exceptions to the anti-deficiency
statutes are provided for in certain instances where the value of the lender's
security has been impaired by acts or omissions of the borrower, for example, in
the event of waste of the property. Finally, other statutory provisions limit
any deficiency judgment against the former borrower following a foreclosure sale
to the excess of the outstanding debt over the fair market value of the property
at the time of the public sale. The purpose of these statutes is generally to
prevent a beneficiary or a mortgagee from obtaining a large deficiency judgment
against the former borrower as a result of low or no bids at the foreclosure
sale.
 
     Generally, Article 9 of the UCC governs foreclosure on Cooperative shares
and the related proprietary lease or occupancy agreement. Some courts have
interpreted section 9-504 of the UCC to prohibit a deficiency award unless the
creditor establishes that the sale of the collateral (which, in the case of a
Cooperative Loan, would be the shares of the Cooperative and the related
proprietary lease or occupancy agreement) was conducted in a commercially
reasonable manner.
 
     In addition to anti-deficiency and related legislation, numerous other
federal and state statutory provisions, including the federal bankruptcy laws,
and state laws affording relief to debtors, may interfere with or affect the
ability of the secured mortgage lender to realize upon its security. For
example, in a proceeding under the federal Bankruptcy Code, a lender may not
foreclose on a mortgaged property without the permission of the bankruptcy
court. The rehabilitation plan proposed by the debtor may provide, if the
mortgaged property is not the debtor's principal residence and the court
determines that the value of the mortgaged property is less than the principal
balance of the mortgage loan, for the reduction of the secured indebtedness to
the value of the mortgaged property as of the date of the commencement of the
bankruptcy, rendering the lender a general unsecured creditor for the
difference, and also may reduce the monthly payments due under such mortgage
loan, change the rate of interest and alter the mortgage loan repayment
schedule. The effect of any such proceedings under the federal Bankruptcy Code,
including but not limited to any automatic stay, could result in delays in
receiving payments on the Loans underlying a Series of Securities and possible
reductions in the aggregate amount of such payments.
 
     The federal tax laws provide priority to certain tax liens over the lien of
a mortgage or secured party.
 
DUE-ON-SALE CLAUSES
 
     Unless otherwise specified in the related Prospectus Supplement, each
conventional Loan will contain a due-on-sale clause which will generally provide
that if the mortgagor or obligor sells, transfers or conveys the Property, the
loan or contract may be accelerated by the mortgagee or secured party. Court
decisions and legislative actions have placed substantial restriction on the
right of lenders to enforce such clauses in many states. For instance, the
California Supreme Court in August 1978 held that due-on-sale clauses were
generally unenforceable. However, the Garn-St Germain Depository Institutions
Act of 1982 (the 'Garn-St Germain Act'), subject to certain exceptions, preempts
state constitutional, statutory and case law prohibiting the enforcement of
due-on-sale clauses. As a result, due-on-sale clauses have become generally
enforceable except in those states whose legislatures exercised their authority
to regulate the enforceability of such clauses with respect to mortgage loans
that were (i) originated or assumed during the 'window period' under the Garn-St
Germain Act which ended in all cases not later than October 15, 1982, and (ii)
originated by lenders other than national banks, federal savings institutions
and federal credit unions. FHLMC has taken the position in its published
mortgage servicing standards that, out of a total of eleven 'window period
states,' five states (Arizona, Michigan, Minnesota, New Mexico and Utah) have
enacted statutes extending, on various terms and for varying periods, the
prohibition on enforcement of due-on-sale clauses with respect to certain
categories of window period loans. Also, the Garn-St Germain Act does
'encourage' lenders to permit assumption of loans at the original rate of
interest or at some other rate less than the average of the original rate and
the market rate.
 
                                       65

     As to loans secured by an owner-occupied residence, the Garn-St Germain Act
sets forth nine specific instances in which a mortgagee covered by the Act may
not exercise its rights under a due-on-sale clause, notwithstanding the fact
that a transfer of the property may have occurred. The inability to enforce a
due-on-sale clause may result in transfer of the related Property to an
uncreditworthy person, which could increase the likelihood of default or may
result in a mortgage bearing an interest rate below the current market rate
being assumed by a new home buyer, which may affect the average life of the
Loans and the number of Loans which may extend to maturity.
 
     In addition, under federal bankruptcy law, due-on-sale clauses may not be
enforceable in bankruptcy proceedings and may, under certain circumstances, be
eliminated in any modified mortgage resulting from such bankruptcy proceeding.
 
ENFORCEABILITY OF PREPAYMENT AND LATE PAYMENT FEES
 
     Forms of notes, mortgages and deeds of trust used by lenders may contain
provisions obligating the borrower to pay a late charge if payments are not
timely made, and in some circumstances may provide for prepayment fees or
penalties if the obligation is paid prior to maturity. In certain states, there
are or may be specific limitations upon the late charges which a lender may
collect from a borrower for delinquent payments. Certain states also limit the
amounts that a lender may collect from a borrower as an additional charge if the
loan is prepaid. Under certain state laws, prepayment charges may not be imposed
after a certain period of time following the origination of mortgage loans with
respect to prepayments on loans secured by liens encumbering owner-occupied
residential properties. Since many of the Properties will be owner-occupied, it
is anticipated that prepayment charges may not be imposed with respect to many
of the Loans. The absence of such a restraint on prepayment, particularly with
respect to fixed rate Loans having higher Loan Rates, may increase the
likelihood of refinancing or other early retirement of such loans or contracts.
Late charges and prepayment fees are typically retained by servicers as
additional servicing compensation.
 
APPLICABILITY OF USURY LAWS
 
     Title V of the Depository Institutions Deregulation and Monetary Control
Act of 1980, enacted in March 1980 ('Title V') provides that state usury
limitations shall not apply to certain types of residential first mortgage loans
originated by certain lenders after March 31, 1980. The Office of Thrift
Supervision, as successor to the Federal Home Loan Bank Board, is authorized to
issue rules and regulations and to publish interpretations governing
implementation of Title V. The statute authorized the states to reimpose
interest rate limits by adopting, before April 1, 1983, a law or constitutional
provision which expressly rejects an application of the federal law. Fifteen
states adopted such a law prior to the April 1, 1983 deadline. In addition, even
where Title V is not so rejected, any state is authorized by the law to adopt a
provision limiting discount points or other charges on mortgage loans covered by
Title V. Certain states have taken action to reimpose interest rate limits
and/or to limit discount points or other charges.
 
THE HOME IMPROVEMENT CONTRACTS
 
     General.  The Home Improvement Contracts, other than those Home Improvement
Contracts that are unsecured or secured by mortgages on real estate (such Home
Improvement Contracts are hereinafter referred to in this section as
'contracts') generally are 'chattel paper' or constitute 'purchase money
security interests' each as defined in the UCC. Pursuant to the UCC, the sale of
chattel paper is treated in a manner similar to perfection of a security
interest in chattel paper. Under the related Agreement, the Depositor will
transfer physical possession of the contracts to the Trustee or a designated
custodian or may retain possession of the contracts as custodian for the
Trustee. In addition, the Depositor will make an appropriate filing of a UCC-1
financing statement in the appropriate states to, among other things, give
notice of the Trust Fund's ownership of the contracts. Unless otherwise
specified in the related Prospectus Supplement, the contracts will not be
stamped or otherwise marked to reflect their assignment from the Depositor to
the Trustee. Therefore, if through negligence, fraud or otherwise, a subsequent
purchaser were able to take physical possession of the contracts without notice
of such assignment, the Trust Fund's interest in the contracts could be
defeated.
 
     Security Interests in Home Improvements.  The contracts that are secured by
the Home Improvements financed thereby grant to the originator of such contracts
a purchase money security interest in such Home
 
                                       66
 

<PAGE>
<PAGE>

Improvements to secure all or part of the purchase price of such Home
Improvements and related services. A financing statement generally is not
required to be filed to perfect a purchase money security interest in consumer
goods. Such purchase money security interests are assignable. In general, a
purchase money security interest grants to the holder a security interest that
has priority over a conflicting security interest in the same collateral and the
proceeds of such collateral. However, to the extent that the collateral subject
to a purchase money security interest becomes a fixture, in order for the
related purchase money security interest to take priority over a conflicting
interest in the fixture, the holder's interest in such Home Improvement must
generally be perfected by a timely fixture filing. In general, a security
interest does not exist under the UCC in ordinary building material incorporated
into an improvement on land. Home Improvement Contracts that finance lumber,
bricks, other types of ordinary building material or other goods that are deemed
to lose such characterization upon incorporation of such materials into the
related property, will not be secured by a purchase money security interest in
the Home Improvement being financed.
 
     Enforcement of Security Interest in Home Improvements.  So long as the Home
Improvement has not become subject to the real estate law, a creditor can
repossess a Home Improvement securing a contract by voluntary surrender, by
'self-help' repossession that is 'peaceful' (i.e., without breach of the peace)
or, in the absence of voluntary surrender and the ability to repossess without
breach of the peace, by judicial process. The holder of a contract must give the
debtor a number of days' notice, which varies from 10 to 30 days depending on
the state, prior to commencement of any repossession. The UCC and consumer
protection laws in most states place restrictions on repossession sales,
including requiring prior notice to the debtor and commercial reasonableness in
effecting such a sale. The law in most states also requires that the debtor be
given notice of any sale prior to resale of the unit that the debtor may redeem
at or before such resale.
 
     Under the laws applicable in most states, a creditor is entitled to obtain
a deficiency judgment from a debtor for any deficiency on repossession and
resale of the property securing the debtor's loan. However, some states impose
prohibitions or limitations on deficiency judgments, and in many cases the
defaulting borrower would have no assets with which to pay a judgment.
 
     Certain other statutory provisions, including federal and state bankruptcy
and insolvency laws and general equitable principles, may limit or delay the
ability of a lender to repossess and resell collateral or enforce a deficiency
judgment.
 
     Consumer Protection Laws.  The so-called 'Holder-in-Due Course' rule of the
Federal Trade Commission is intended to defeat the ability of the transferor of
a consumer credit contract which is the seller of goods which gave rise to the
transaction (and certain related lenders and assignees) to transfer such
contract free of notice of claims by the debtor thereunder. The effect of this
rule is to subject the assignee of such a contract to all claims and defenses
which the debtor could assert against the seller of goods. Liability under this
rule is limited to amounts paid under a contract; however, the obligor also may
be able to assert the rule to set off remaining amounts due as a defense against
a claim brought by the Trustee against such obligor. Numerous other federal and
state consumer protection laws impose requirements applicable to the origination
and lending pursuant to the contracts, including the Truth in Lending Act, the
Federal Trade Commission Act, the Fair Credit Billing Act, the Fair Credit
Reporting Act, the Equal Credit Opportunity Act, the Fair Debt Collection
Practices Act and the Uniform Consumer Credit Code. In the case of some of these
laws, the failure to comply with their provisions may affect the enforceability
of the related contract.
 
     Applicability of Usury Laws.  Title V of the Depository Institutions
Deregulation and Monetary Control Act of 1980, as amended ('Title V'), provides
that, subject to the following conditions, state usury limitations shall not
apply to any contract which is secured by a first lien on certain kinds of
consumer goods. The contracts would be covered if they satisfy certain
conditions governing, among other things, the terms of any prepayments, late
charges and deferral fees and requiring a 30-day notice period prior to
instituting any action leading to repossession of the related unit.
 
     Title V authorized any state to reimpose limitations on interest rates and
finance charges by adopting before April 1, 1983 a law or constitutional
provision which expressly rejects application of the federal law. Fifteen states
adopted such a law prior to the April 1, 1983 deadline. In addition, even where
Title V was not so rejected, any state is authorized by the law to adopt a
provision limiting discount points or other charges on loans covered by Title V.

INSTALLMENT CONTRACTS
 
     The Loans may also consist of installment contracts. Under an installment
contract ('Installment Contract') the seller (hereinafter referred to in this
section as the 'lender') retains legal title to the property and enters into an
agreement with the purchaser hereinafter referred to in this section as the
'borrower') for the payment of the purchase price, plus interest, over the term
of such contract. Only after full performance by the borrower of the contract is
the lender obligated to convey title to the property to the purchaser. As with
mortgage or deed of trust financing, during the effective period of the
Installment Contract, the borrower is generally responsible for maintaining the
property in good condition and for paying real estate taxes, assessments and
hazard insurance premiums associated with the property.
 
     The method of enforcing the rights of the lender under an Installment
Contract varies on a state-by-state basis depending upon the extent to which
state courts are willing, or able pursuant to state statute, to enforce the
contract strictly according to its terms. The terms of Installment Contracts
generally provide that upon a default by the borrower, the borrower loses his or
her right to occupy the property, the entire indebtedness is accelerated, and
the buyer's equitable interest in the property is forfeited. The lender in such
a situation does not have to foreclose in order to obtain title to the property,
although in some cases a quiet title action is in order if the borrower has
filed the Installment Contract in local land records and an ejectment action may
be necessary to recover possession. In a few states, particularly in cases of
borrower default during the early years of an Installment Contract, the courts
will permit ejectment of the buyer and a forfeiture of his or her interest in
the property. However, most state legislatures have enacted provisions by
analogy to mortgage law protecting borrowers under Installment Contracts from
the harsh consequences of forfeiture. Under such statutes, a judicial or
nonjudicial foreclosure may be required, the lender may be required to give
notice of default and the borrower may be granted some grace period during which
the Installment Contract may be reinstated upon full payment of the default
amount and the borrower may have a post-foreclosure statutory redemption right.
In other states, courts in equity may permit a borrower with significant
investment in the property under an Installment Contract for the sale of real
estate to share in the proceeds of sale of the property after the indebtedness
is repaid or may otherwise refuse to enforce the forfeiture clause.
Nevertheless, generally speaking, the lender's procedures for obtaining
possession and clear title under an Installment Contract in a given state are
simpler and less time-consuming and costly than are the procedures for
foreclosing and obtaining clear title to a property subject to one or more
liens.
 
SOLDIERS' AND SAILORS' CIVIL RELIEF ACT
 
     Generally, under the terms of the Soldiers' and Sailors' Civil Relief Act
of 1940, as amended (the 'Relief Act'), a borrower who enters military service
after the origination of such borrower's Loan (including a borrower who is a
member of the National Guard or is in reserve status at the time of the
origination of the Loan and is later called to active duty) may not be charged
interest above an annual rate of 6% during the period of such borrower's active
duty status, unless a court orders otherwise upon application of the lender. It
is possible that such interest rate limitation could have an effect, for an
indeterminate period of time, on the ability of the Master Servicer to collect
full amounts of interest on certain of the Loans. Unless otherwise provided in
the related Prospectus Supplement, any shortfall in interest collections
resulting from the application of the Relief Act could result in losses to
Securityholders. The Relief Act also imposes limitations which would impair the
ability of the Master Servicer to foreclose on an affected Loan during the
borrower's period of active duty status. Moreover, the Relief Act permits the
extension of a Loan's maturity and the re-adjustment of its payment schedule
beyond the completion of military service. Thus, in the event that such a Loan
goes into default, there may be delays and losses occasioned by the inability to
realize upon the Property in a timely fashion.
 
JUNIOR MORTGAGES; RIGHTS OF SENIOR MORTGAGEES
 
     To the extent that the Loans comprising the Trust Fund for a Series are
secured by mortgages which are junior to other mortgages held by other lenders
or institutional investors, the rights of the Trust Fund (and therefore the
Securityholders), as mortgagee under any such junior mortgage, are subordinate
to those of any mortgagee under any senior mortgage. The senior mortgagee has
the right to receive hazard insurance and condemnation proceeds and to cause the
property securing the Loan to be sold upon default of the mortgagor, thereby
extinguishing thejunior mortgagee's lien unless the junior mortgagee asserts its
subordinate interest in the property in foreclosure litigation and, possibly,
satisfies the defaulted senior mortgage. A junior mortgagee
 
                                       68
 

<PAGE>
<PAGE>

may satisfy a defaulted senior loan in full and, in some states, may cure a
default and bring the senior loan current, in either event adding the amounts
expended to the balance due on the junior loan. In most states, absent a
provision in the mortgage or deed of trust, no notice of default is required to
be given to a junior mortgagee.
 
     The standard form of the mortgage used by most institutional lenders
confers on the mortgagee the right both to receive all proceeds collected under
any hazard insurance policy and all awards made in connection with condemnation
proceedings, and to apply such proceeds and awards to any indebtedness secured
by the mortgage, in such order as the mortgagee may determine. Thus, in the
event improvements on the property are damaged or destroyed by fire or other
casualty, or in the event the property is taken by condemnation, the mortgagee
or beneficiary under senior mortgages will have the prior right to collect any
insurance proceeds payable under a hazard insurance policy and any award of
damages in connection with the condemnation and to apply the same to the
indebtedness secured by the senior mortgages. Proceeds in excess of the amount
of senior mortgage indebtedness, in most cases, may be applied to the
indebtedness of a junior mortgage.
 
     Another provision sometimes found in the form of the mortgage or deed of
trust used by institutional lenders obligates the mortgagor to pay before
delinquency all taxes and assessments on the property and, when due, all
encumbrances, charges and liens on the property which appear prior to the
mortgage or deed of trust, to provide and maintain fire insurance on the
property, to maintain and repair the property and not to commit or permit any
waste thereof, and to appear in and defend any action or proceeding purporting
to affect the property or the rights of the mortgagee under the mortgage. Upon a
failure of the mortgagor to perform any of these obligations, the mortgagee is
given the right under certain mortgages to perform the obligation itself, at its
election, with the mortgagor agreeing to reimburse the mortgagee for any sums
expended by the mortgagee on behalf of the mortgagor. All sums so expended by
the mortgagee become part of the indebtedness secured by the mortgage.
 
     The form of credit line trust deed or mortgage generally used by most
institutional lenders which make Revolving Credit Line Loans typically contains
a 'future advance' clause, which provides, in essence, that additional amounts
advanced to or on behalf of the borrower by the beneficiary or lender are to be
secured by the deed of trust or mortgage. Any amounts so advanced after the
Cut-off Date with respect to any Mortgage will not be included in the Trust
Fund. The priority of the lien securing any advance made under the clause may
depend in most states on whether the deed of trust or mortgage is called and
recorded as a credit line deed of trust or mortgage. If the beneficiary or
lender advances additional amounts, the advance is entitled to receive the same
priority as amounts initially advanced under the trust deed or mortgage,
notwithstanding the fact that there may be junior trust deeds or mortgages and
other liens which intervene between the date of recording of the trust deed or
mortgage and the date of the future advance, and notwithstanding that the
beneficiary or lender had actual knowledge of such intervening junior trust
deeds or mortgages and other liens at the time of the advance. In most states,
the trust deed or mortgage lien securing mortgage loans of the type which
includes home equity credit lines applies retroactively to the date of the
original recording of the trust deed or mortgage, provided that the total amount
of advances under the home equity credit line does not exceed the maximum
specified principal amount of the recorded trust deed or mortgage, except as to
advances made after receipt by the lender of a written notice of lien from a
judgment lien creditor of the trustor.
 
THE TITLE I PROGRAM
 
     General.  Certain of the Loans contained in a Trust Fund may be loans
insured under the FHA Title I Credit Insurance program created pursuant to
Sections 1 and 2(a) of the National Housing Act of 1934 (the 'Title I Program').
Under the Title I Program, the FHA is authorized and empowered to insure
qualified lending institutions against losses on eligible loans. The Title I
Program operates as a coinsurance program in which the FHA insures up to 90% of
certain losses incurred on an individual insured loan, including the unpaid
principal balance of the loan, but only to the extent of the insurance coverage
available in the lender's FHA insurance coverage reserve account. The owner of
the loan bears the uninsured loss on each loan.
 
     The types of loans which are eligible for insurance by the FHA under the
Title I Program include property improvement loans ('Property Improvement Loans'
or 'Title I Loans'). A Property Improvement Loan or Title I Loan means a loan
made to finance actions or items that substantially protect or improve the basic
livability or utility of a property and includes single family improvement
loans.
 
                                       69
 

<PAGE>
<PAGE>

     There are two basic methods of lending or originating such loans which
include a 'direct loan' or a 'dealer loan'. With respect to a direct loan, the
borrower makes application directly to a lender without any assistance from a
dealer, which application may be filled out by the borrower or by a person
acting at the direction of the borrower who does not have a financial interest
in the loan transaction, and the lender may disburse the loan proceeds solely to
the borrower or jointly to the borrower and other parties to the transaction.
With respect to a dealer loan, the dealer, who has a direct or indirect
financial interest in the loan transaction, assists the borrower in preparing
the loan application or otherwise assists the borrower in obtaining the loan
from lender and the lender may distribute proceeds solely to the dealer or the
borrower or jointly to the borrower and the dealer or other parties. With
respect to a dealer Title I Loan, a dealer may include a seller, a contractor or
supplier of goods or services.
 
     Loans insured under the Title I Program are required to have fixed interest
rates and, generally, provide for equal installment payments due weekly,
biweekly, semi-monthly or monthly, except that a loan may be payable quarterly
or semi-annually in order to correspond with the borrower's irregular flow of
income. The first or last payments (or both) may vary in amount but may not
exceed 150% of the regular installment payment, and the first scheduled payment
may be due no later than two months from the date of the loan. The note must
contain a provision permitting full or partial prepayment of the loan. The
interest rate may be established by the lender and must be fixed for the term of
the loan and recited in the note. Interest on an insured loan must accrue from
the date of the loan and be calculated on a simple interest basis. The lender
must assure that the note and all other documents evidencing the loan are in
compliance with applicable federal, state and local laws.
 
     Each insured lender is required to use prudent lending standards in
underwriting individual loans and to satisfy the applicable loan underwriting
requirements under the Title I Program prior to its approval of the loan and
disbursement of loan proceeds. Generally, the lender must exercise prudence and
diligence to determine whether the borrower and any co-maker is solvent and an
acceptable credit risk, with a reasonable ability to make payments on the loan
obligation. The lender's credit application and review must determine whether
the borrower's income will be adequate to meet the periodic payments required by
the loan, as well as the borrower's other housing and recurring expenses, which
determination must be made in accordance with the expense-to-income ratios
published by the Secretary of HUD.
 
     Under the Title I Program, the FHA does not review or approve for
qualification for insurance the individual loans insured thereunder at the time
of approval by the lending institution (as is typically the case with other
federal loan programs). If, after a loan has been made and reported for
insurance under the Title I Program, the lender discovers any material
misstatement of fact or that the loan proceeds have been misused by the
borrower, dealer or any other party, it shall promptly report this to the FHA.
In such case, provided that the validity of any lien on the property has not
been impaired, the insurance of the loan under the Title I Program will not be
affected unless such material misstatements of fact or misuse of loan proceeds
was caused by (or was knowingly sanctioned by) the lender or its employees.
 
     Requirements for Title I Loans.  The maximum principal amount for Title I
Loans must not exceed the actual cost of the project plus any applicable fees
and charges allowed under the Title I Program; provided that such maximum amount
does not exceed $25,000 (or the current applicable amount) for a single family
property improvement loan. Generally, the term of a Title I Loan may not be less
than six months nor greater than 20 years and 32 days. A borrower may obtain
multiple Title I Loans with respect to multiple properties, and a borrower may
obtain more than one Title I Loan with respect to a single property, in each
case as long as the total outstanding balance of all Title I Loans in the same
property does not exceed the maximum loan amount for the type of Title I Loan
thereon having the highest permissible loan amount.
 
     Borrower eligibility for a Title I Loan requires that the borrower have at
least a one-half interest in either fee simple title to the real property, a
lease thereof for a term expiring at least six months after the final maturity
of the Title I Loan or a recorded land installment contract for the purchase of
the real property, and that the borrower have equity in the property being
improved at least equal to the amount of the Title I Loan if such loan amount
exceeds $15,000. Any Title I Loan in excess of $7,500 must be secured by a
recorded lien on the improved property which is evidenced by a mortgage or deed
of trust executed by the borrower and all other owners in fee simple.
 
     The proceeds from a Title I Loan may be used only to finance property
improvements which substantially protect or improve the basic livability or
utility of the property as disclosed in the loan application. The Secretary of
HUD has published a list of items and activities which cannot be financed with
proceeds from any
 
                                       70
 

<PAGE>
<PAGE>

Title I Loan and from time to time the Secretary of HUD may amend such list of
items and activities. With respect to any dealer Title I Loan, before the lender
may disburse funds, the lender must have in its possession a completion
certificate on a HUD approved form, signed by the borrower and the dealer. With
respect to any direct Title I Loan, the borrower is required to submit to the
lender, promptly upon completion of the improvements but not later than six
months after disbursement of the loan proceeds with one six month extension if
necessary, a completion certificate, signed by the borrower. The lender or its
agent is required to conduct an on-site inspection on any Title I Loan where the
principal obligation is $7,500 or more, and on any direct Title I Loan where the
borrower fails to submit a completion certificate.
 
     FHA Insurance Coverage.  Under the Title I Program the FHA establishes an
insurance coverage reserve account for each lender which has been granted a
Title I insurance contract. The amount of insurance coverage in this account is
10% of the amount disbursed, advanced or expended by the lender in originating
or purchasing eligible loans registered with FHA for Title I insurance, with
certain adjustments. The balance in the insurance coverage reserve account is
the maximum amount of insurance claims the FHA is required to pay. Loans to be
insured under the Title I Program will be registered for insurance by the FHA
and the insurance coverage attributable to such loans will be included in the
insurance coverage reserve account for the originating or purchasing lender
following the receipt and acknowledgment by the FHA of a loan report on the
prescribed form pursuant to the Title I regulations. The FHA charges a fee of
0.50% per annum of the net proceeds (the original balance) of any eligible loan
so reported and acknowledged for insurance by the originating lender. The FHA
bills the lender for the insurance premium on each insured loan annually, on
approximately the anniversary date of the loan's origination. If an insured loan
is prepaid during the year, FHA will not refund the insurance premium, but will
abate any insurance charges falling due after such prepayment.
 
     Under the Title I Program the FHA will reduce the insurance coverage
available in the lender's FHA insurance coverage reserve account with respect to
loans insured under the lender's contract of insurance by (i) the amount of the
FHA insurance claims approved for payment relating to such insured loans and
(ii) the amount of insurance coverage attributable to insured loans sold by the
lender. The balance of the lender's FHA insurance coverage reserve account will
be further adjusted as required under Title I or by the FHA, and the insurance
coverage therein may be earmarked with respect to each or any eligible loans
insured thereunder, if a determination is made by the Secretary of HUD that it
is in its interest to do so. Originations and acquisitions of new eligible loans
will continue to increase a lender's insurance coverage reserve account balance
by 10% of the amount disbursed, advanced or expended in originating or acquiring
such eligible loans registered with the FHA for insurance under the Title I
Program. The Secretary of HUD may transfer insurance coverage between insurance
coverage reserve accounts with earmarking with respect to a particular insured
loan or group of insured loans when a determination is made that it is in the
Secretary's interest to do so.
 
     The lender may transfer (except as collateral in a bona fide loan
transaction) insured loans and loans reported for insurance only to another
qualified lender under a valid Title I contract of insurance. Unless an insured
loan is transferred with recourse or with a guaranty or repurchase agreement,
the FHA, upon receipt of written notification of the transfer of such loan in
accordance with the Title I regulations, will transfer from the transferor's
insurance coverage reserve account to the transferee's insurance coverage
reserve account an amount, if available, equal to 10% of the actual purchase
price or the net unpaid principal balance of such loan (whichever is less).
However, under the Title I Program not more than $5,000 in insurance coverage
shall be transferred to or from a lender's insurance coverage reserve account
during any October 1 to September 30 period without the prior approval of the
Secretary of HUD.
 
     Claims Procedures Under Title I.  Under the Title I Program the lender may
accelerate an insured loan following a default on such loan only after the
lender or its agent has contacted the borrower in a face-to-face meeting or by
telephone to discuss the reasons for the default and to seek its cure. If the
borrower does not cure the default or agree to a modification agreement or
repayment plan, the lender will notify the borrower in writing that, unless
within 30 days the default is cured or the borrower enters into a modification
agreement or repayment plan, the loan will be accelerated and that, if the
default persists, the lender will report the default to an appropriate credit
agency. The lender may rescind the acceleration of maturity after full payment
is due and reinstate the loan only if the borrower brings the loan current,
executes a modification agreement or agrees to an acceptable repayment plan.
 
     Following acceleration of maturity upon a secured Title I Loan, the lender
may either (a) proceed against the property under any security instrument, or
(b) make a claim under the lender's contract of insurance. If the
 
                                       71

lender chooses to proceed against the property under a security instrument (or
if it accepts a voluntary conveyance or surrender of the property), the lender
may file an insurance claim only with the prior approval of the Secretary of
HUD.
 
     When a lender files an insurance claim with the FHA under the Title I
Program, the FHA reviews the claim, the complete loan file and documentation of
the lender's efforts to obtain recourse against any dealer who has agreed
thereto, certification of compliance with applicable state and local laws in
carrying out any foreclosure or repossession, and evidence that the lender has
properly filed proofs of claims, where the borrower is bankrupt or deceased.
Generally, a claim for reimbursement for loss on any Title I Loan must be filed
with the FHA no later than nine months after the date of default of such loan.
Concurrently with filing the insurance claim, the lender shall assign to the
United States of America the lender's entire interest in the loan note (or a
judgment in lieu of the note), in any security held and in any claim filed in
any legal proceedings. If, at the time the note is assigned to the United
States, the Secretary has reason to believe that the note is not valid or
enforceable against the borrower, the FHA may deny the claim and reassign the
note to the lender. If either such defect is discovered after the FHA has paid a
claim, the FHA may require the lender to repurchase the paid claim and to accept
a reassignment of the loan note. If the lender subsequently obtains a valid and
enforceable judgment against the borrower, the lender may resubmit a new
insurance claim with an assignment of the judgment. The FHA may contest any
insurance claim and make a demand for repurchase of the loan at any time up to
two years from the date the claim was certified for payment and may do so
thereafter in the event of fraud or misrepresentation on the part of the lender.
 
     Under the Title I Program the amount of an FHA insurance claim payment,
when made, is equal to the Claimable Amount, up to the amount of insurance
coverage in the lender's insurance coverage reserve account. For the purposes
hereof, the 'Claimable Amount' means an amount equal to 90% of the sum of: (a)
the unpaid loan obligation (net unpaid principal and the uncollected interest
earned to the date of default) with adjustments thereto if the lender has
proceeded against property securing such loan; (b) the interest on the unpaid
amount of the loan obligation from the date of default to the date of the
claim's initial submission for payment plus 15 calendar days (but not to exceed
9 months from the date of default), calculated at the rate of 7% per annum; (c)
the uncollected court costs; (d) the attorney's fees not to exceed $500; and (e)
the expenses for recording the assignment of the security to the United States.
 
CONSUMER PROTECTION LAWS
 
     Numerous federal and state consumer protection laws impose substantive
requirements upon mortgage lenders in connection with the origination, servicing
and enforcement of loans secured by Single Family Properties. These laws include
the federal Truth-in-Lending Act and Regulation Z promulgated thereunder, Real
Estate Settlement Procedures Act and Regulation B promulgated thereunder, Equal
Credit Opportunity Act, Fair Credit Billing Act, Fair Credit Reporting Act and
related statutes and regulations. In particular, Regulation Z, requires certain
disclosures to the borrowers regarding the terms of the Loans; the Equal Credit
Opportunity Act and Regulation B promulgated thereunder prohibit discrimination
on the basis of age, race, color, sex, religion, marital status, national
origin, receipt of public assistance or the exercise of any right under the
Consumer Credit Protection Act, in the extension of credit; the Fair Credit
Reporting Act regulates the use and reporting of information relatedto the
borrower's credit experience. Certain provisions of these laws impose specific
statutory liabilities upon lenders who fail to comply therewith. In addition,
violations of such laws may limit the ability of the Sellers to collect all or
part of the principal of or interest on the Loans and could subject the Sellers
and in some cases their assignees to damages and administrative enforcement.

                        FEDERAL INCOME TAX CONSEQUENCES
 
GENERAL
 
     The following is a summary of the anticipated material federal income tax
consequences of the purchase, ownership, and disposition of the Securities and
is based on advice of Brown & Wood LLP, special counsel to the Depositor. The
summary is based upon the provisions of the Code, the regulations promulgated
thereunder, including, where applicable, proposed regulations, and the judicial
and administrative rulings and decisions now in effect, all of which are subject
to change or possible differing interpretations. The statutory provisions,
regulations, and interpretations on which this interpretation is based are
subject to change, and such a change could apply retroactively.
 
     The summary does not purport to deal with all aspects of federal income
taxation that may affect particular investors in light of their individual
circumstances, nor with certain types of investors subject to special treatment
under the federal income tax laws. This summary focuses primarily upon investors
who will hold Securities as 'capital assets' (generally, property held for
investment) within the meaning of Section 1221 of the Code, but much of the
discussion is applicable to other investors as well. Prospective Investors are
advised to consult their own tax advisers concerning the federal, state, local
and any other tax consequences to them of the purchase, ownership and
disposition of the Securities.
 
     The federal income tax consequences to Holders will vary depending on
whether (i) the Securities of a Series are classified as indebtedness; (ii) an
election is made to treat the Trust Fund relating to a particular Series of
Securities as a real estate mortgage investment conduit ('REMIC') under the
Internal Revenue Code of 1986, as amended (the 'Code'); (iii) the Securities
represent an ownership interest in some or all of the assets included in the
Trust Fund for a Series; or (iv) an election is made to treat the Trust Fund
relating to a particular Series of Certificates as a partnership. The Prospectus
Supplement for each Series of Securities will specify how the Securities will be
treated for federal income tax purposes and will discuss whether a REMIC
election, if any, will be made with respect to such Series. Prior to issuance of
each Series of Securities, the Depositor shall file with the Commission a Form
8-K on behalf of the related Trust Fund containing an opinion of Brown & Wood
LLP with respect to the validity of the information set forth under 'Federal
Income Tax Consequences' herein and in the related Prospectus Supplement.
 
TAXATION OF DEBT SECURITIES
 
     Interest and Acquisition Discount. Securities representing regular
interests in a REMIC ('Regular Interest Securities') are generally taxable to
holders in the same manner as evidences of indebtedness issued by the REMIC.
Stated interest on the Regular Interest Securities will be taxable as ordinary
income and taken into account using the accrual method of accounting, regardless
of the Holder's normal accounting method. Interest (other than original issue
discount) on Securities (other than Regular Interest Securities) that are
characterized as indebtedness for federal income tax purposes will be includible
in income by holders thereof in accordance with their usual methods of
accounting. Securities characterized as debt for federal income tax purposes and
Regular Interest Securities will be referred to hereinafter collectively as
'Debt Securities.'
 
     Debt Securities that are Compound Interest Securities will, and certain of
the other Debt Securities may, be issued with 'original issue discount' ('OID').
The following discussion is based in part on the rules governing OID which are
set forth in Sections 1271-1275 of the Code and the Treasury regulations issued
thereunder on February 2, 1994, as amended on June 11, 1996, (the 'OID
Regulations'). A Holder should be aware, however, that the OID Regulations do
not adequately address certain issues relevant to prepayable securities, such as
the Debt Securities.
 
     In general, OID, if any, will equal the difference between the stated
redemption price at maturity of a Debt Security and its issue price. A holder of
a Debt Security must include such OID in gross income as ordinary interest
income as it accrues under a method taking into account an economic accrual of
the discount. In general, OID must be included in income in advance of the
receipt of the cash representing that income. The amount of OID on a Debt
Security will be considered to be zero if it is less than a de minimis amount
determined under the Code.
 
     The issue price of a Debt Security is the first price at which a
substantial amount of Debt Securities of that class are sold to the public
(excluding bond houses, brokers, underwriters or wholesalers). If less than a
 
                                       73
 

<PAGE>
<PAGE>

substantial amount of a particular class of Debt Securities is sold for cash on
or prior to the related Closing Date, the issue price for such class will be
treated as the fair market value of such class on such Closing Date. The issue
price of a Debt Security also includes the amount paid by an initial Debt
Security holder for accrued interest that relates to a period prior to the issue
date of the Debt Security. The stated redemption price at maturity of a Debt
Security includes the original principal amount of the Debt Security, but
generally will not include distributions of interest if such distributions
constitute 'qualified stated interest.'
 
     Under the OID Regulations, qualified stated interest generally means
interest payable at a single fixed rate or qualified variable rate (as described
below) provided that such interest payments are unconditionally payable at
intervals of one year or less during the entire term of the Debt Security. The
OID Regulations state that interest payments are unconditionally payable only if
a late payment or nonpayment is expected to be penalized or reasonable remedies
exist to compel payment. Certain Debt Securities may provide for default
remedies in the event of late payment or nonpayment of interest. The interest on
such Debt Securities will be unconditionally payable and constitute qualified
stated interest, not OID. However, absent clarification of the OID Regulations,
where Debt Securities do not provide for default remedies, the interest payments
will be included in the Debt Security's stated redemption price at maturity and
taxed as OID. Interest is payable at a single fixed rate only if the rate
appropriately takes into account the length of the interval between payments.
Distributions of interest on Debt Securities with respect to which deferred
interest will accrue, will not constitute qualified stated interest payments, in
which case the stated redemption price at maturity of such Debt Securities
includes all distributions of interest as well as principal thereon. Where the
interval between the issue date and the first Distribution Date on a Debt
Security is either longer or shorter than the interval between subsequent
Distribution Dates, all or part of the interest foregone, in the case of the
longer interval, and all of the additional interest, in the case of the shorter
interval, will be included in the stated redemption price at maturity and tested
under the de minimis rule described below. In the case of a Debt Security with a
long first period which has non-de minimis OID, all stated interest in excess of
interest payable at the effective interest rate for the long first period will
be included in the stated redemption price at maturity and the Debt Security
will generally have OID. Holders of Debt Securities should consult their own tax
advisors to determine the issue price and stated redemption price at maturity of
a Debt Security.
 
     Under the de minimis rule, OID on a Debt Security will be considered to be
zero if such OID is less than 0.25% of the stated redemption price at maturity
of the Debt Security multiplied by the weighted average maturity of the Debt
Security. For this purpose, the weighted average maturity of the Debt Security
is computed as the sum of the amounts determined by multiplying the number of
full years (i.e., rounding down partial years) from the issue date until each
distribution in reduction of stated redemption price at maturity is scheduled to
be made by a fraction, the numerator of which is the amount of each distribution
included in the stated redemption price at maturity of the Debt Security and the
denominator of which is the stated redemption price at maturity of the Debt
Security. Holders generally must report de minimis OID pro rata as principal
payments are received, and such income will be capital gain if the Debt Security
is held as a capital asset. However, accrual method holders may elect to accrue
all de minimis OID as well as market discount under a constant interest method.
 
     Debt Securities may provide for interest based on a qualified variable
rate. Under the OID Regulations, interest is treated as payable at a qualified
variable rate and not as contingent interest if, generally, (i) such interest is
unconditionally payable at least annually, (ii) the issue price of the debt
instrument does not exceed the total noncontingent principal payments and (iii)
interest is based on a 'qualified floating rate,' an 'objective rate,' or a
combination of 'qualified floating rates' that do not operate in a manner that
significantly accelerates or defers interest payments on such Debt Security. In
the case of Compound Interest Securities, certain Interest Weighted Securities
(as defined herein), and certain of the other Debt Securities, none of the
payments under the instrument will be considered qualified stated interest, and
thus the aggregate amount of all payments will be included in the stated
redemption price.
 
     The Internal Revenue Services (the 'IRS') recently issued final regulations
(the 'Contingent Regulations') governing the calculation of OID on instruments
having contingent interest payments. The Contingent Regulations specifically do
not apply for purposes of calculating OID on debt instruments subject to Code
Section 1272(a)(6), such as the Debt Security. Additionally, the OID Regulations
do not contain provisions specifically interpreting Code Section 1272(a)(6).
Until the Treasury issues guidance to the contrary, the Trustee intends to base
its computation on Code Section 1272(a)(6) and the OID Regulations as described
in this
 
                                       74
 

<PAGE>
<PAGE>

Prospectus. However, because no regulatory guidance currently exists under Code
Section 1272(a)(6), there can be no assurance that such methodology represents
the correct manner of calculating OID.
 
     The holder of a Debt Security issued with OID must include in gross income,
for all days during its taxable year on which it holds such Debt Security, the
sum of the 'daily portions' of such original issue discount. The amount of OID
includible in income by a holder will be computed by allocating to each day
during a taxable year a pro rata portion of the original issue discount that
accrued during the relevant accrual period. In the case of a Debt Security that
is not a Regular Interest Security and the principal payments on which are not
subject to acceleration resulting from prepayments on the Loans, the amount of
OID includible in income of a Holder for an accrual period (generally the period
over which interest accrues on the debt instrument) will equal the product of
the yield to maturity of the Debt Security and the adjusted issue price of the
Debt Security, reduced by any payments of qualified stated interest. The
adjusted issue price is the sum of its issue price plus prior accruals or OID,
reduced by the total payments made with respect to such Debt Security in all
prior periods, other than qualified stated interest payments.
 
     The amount of OID to be included in income by a holder of a debt
instrument, such as certain Classes of the Debt Securities, that is subject to
acceleration due to prepayments on other debt obligations securing such
instruments (a 'Pay-Through Security'), is computed by taking into account the
anticipated rate of prepayments assumed in pricing the debt instrument (the
'Prepayment Assumption'). The amount of OID that will accrue during an accrual
period on a Pay-Through Security is the excess (if any) of the sum of (a) the
present value of all payments remaining to be made on the Pay-Through Security
as of the close of the accrual period and (b) the payments during the accrual
period of amounts included in the stated redemption price of the Pay-Through
Security, over the adjusted issue price of the Pay-Through Security at the
beginning of the accrual period. The present value of the remaining payments is
to be determined on the basis of three factors: (i) the original yield to
maturity of the Pay-Through Security (determined on the basis of compounding at
the end of each accrual period and properly adjusted for the length of the
accrual period), (ii) events which have occurred before the end of the accrual
period and (iii) the assumption that the remaining payments will be made in
accordance with the original Prepayment Assumption. The effect of this method is
to increase the portions of OID required to be included in income by a Holder to
take into account prepayments with respect to the Loans at a rate that exceeds
the Prepayment Assumption, and to decrease (but not below zero for any period)
the portions of original issue discount required to be included in income by a
Holder of a Pay-Through Security to take into account prepayments with respect
to the Loans at a rate that is slower than the Prepayment Assumption. Although
original issue discount will be reported to Holders of Pay-Through Securities
based on the Prepayment Assumption, no representation is made to Holders that
Loans will be prepaid at that rate or at any other rate.
 
     The Depositor may adjust the accrual of OID on a Class of Regular Interest
Securities (or other regular interests in a REMIC) in a manner that it believes
to be appropriate, to take account of realized losses on the Loans, although the
OID Regulations do not provide for such adjustments. If the IRS were to require
that OID be accrued without such adjustments, the rate of accrual of OID for a
Class of Regular Interest Securities could increase.
 
     Certain classes of Regular Interest Securities may represent more than one
class of REMIC regular interests. Unless otherwise provided in the related
Prospectus Supplement, the Trustee intends, based on the OID Regulations, to
calculate OID on such Securities as if, solely for the purposes of computing
OID, the separate regular interests were a single debt instrument.
 
     A subsequent holder of a Debt Security will also be required to include OID
in gross income, but such a holder who purchases such Debt Security for an
amount that exceeds its adjusted issue price will be entitled (as will an
initial holder who pays more than a Debt Security's issue price) to offset such
OID by comparable economic accruals of portions of such excess.
 
     Effects of Defaults and Delinquencies.  Holders will be required to report
income with respect to the related Securities under an accrual method without
giving effect to delays and reductions in distributions attributable to a
default or delinquency on the Loans, except possibly to the extent that it can
be established that such amounts are uncollectible. As a result, the amount of
income (including OID) reported by a holder of such a Security in any period
could significantly exceed the amount of cash distributed to such holder in that
period. The holder will eventually be allowed a loss (or will be allowed to
report a lesser amount of income) to the extent that the aggregate amount of
distributions on the Securities is deducted as a result of a Loan default.
 
                                       75
 

<PAGE>
<PAGE>

However, the timing and character of such losses or reductions in income are
uncertain and, accordingly, holders of Securities should consult their own tax
advisors on this point.
 
     Interest Weighted Securities.  It is not clear how income should be accrued
with respect to Regular Interest Securities or Stripped Securities (as defined
under ' -- Tax Status as a Grantor Trust; General' herein) the payments on which
consist solely or primarily of a specified portion of the interest payments on
qualified mortgages held by the REMIC or on Loans underlying Pass-Through
Securities ('Interest Weighted Securities'). The Issuer intends to take the
position that all of the income derived from an Interest Weighted Security
should be treated as OID and that the amount and rate of accrual of such OID
should be calculated by treating the Interest Weighted Security as a Compound
Interest Security. However, in the case of Interest Weighted Securities that are
entitled to some payments of principal and that are Regular Interest Securities
the Internal Revenue Service could assert that income derived from an Interest
Weighted Security should be calculated as if the Security were a security
purchased at a premium equal to the excess of the price paid by such holder for
such Security over its stated principal amount, if any. Under this approach, a
holder would be entitled to amortize such premium only if it has in effect an
election under Section 171 of the Code with respect to all taxable debt
instruments held by such holder, as described below. Alternatively, the Internal
Revenue Service could assert that an Interest Weighted Security should be
taxable under the rules governing bonds issued with contingent payments. Such
treatment may be more likely in the case of Interest Weighted Securities that
are Stripped Securities as described below. See ' -- Tax Status as a Grantor
Trust -- Discount or Premium on Pass-Through Securities.'
 
     Variable Rate Debt Securities.  In the case of Debt Securities bearing
interest at a rate that varies directly, according to a fixed formula, with an
objective index, it appears that (i) the yield to maturity of such Debt
Securities and (ii) in the case of Pay-Through Securities, the present value of
all payments remaining to be made on such Debt Securities, should be calculated
as if the interest index remained at its value as of the issue date of such
Securities. Because the proper method of adjusting accruals of OID on a variable
rate Debt Security is uncertain, holders of variable rate Debt Securities should
consult their own tax advisers regarding the appropriate treatment of such
Securities for federal income tax purposes.
 
     Market Discount.  A purchaser of a Security may be subject to the market
discount rules of Sections 1276-1278 of the Code. A Holder that acquires a Debt
Security with more than a prescribed de minimis amount of 'market discount'
(generally, the excess of the principal amount of the Debt Security over the
purchaser's purchase price) will be required to include accrued market discount
in income as ordinary income in each month, but limited to an amount not
exceeding the principal payments on the Debt Security received in that month
and, if the Securities are sold, the gain realized. Such market discount would
accrue in a manner to be provided in Treasury regulations but, until such
regulations are issued, such market discount would in general accrue either (i)
on the basis of a constant yield (in the case of a Pay-Through Security, taking
into account a prepayment assumption) or (ii) in the ratio of (a) in the case of
Securities (or in the case of a Pass-Through Security (as defined herein), as
set forth below, the Loans underlying such Security) not originally issued with
original issue discount, stated interest payable in the relevant period to total
stated interest remaining to be paid at the beginning of the period or (b) in
the case of Securities (or, in the case of a Pass-Through Security, as described
below, the Loans underlying such Security) originally issued at a discount, OID
in the relevant period to total OID remaining to be paid.
 
     Section 1277 of the Code provides that, regardless of the origination date
of the Debt Security (or, in the case of a Pass-Through Security, the Loans),
the excess of interest paid or accrued to purchase or carry a Security (or, in
the case of a Pass-Through Security, as described below, the underlying Loans)
with market discount over interest received on such Security is allowed as a
current deduction only to the extent such excess is greater than the market
discount that accrued during the taxable year in which such interest expense was
incurred. In general, the deferred portion of any interest expense will be
deductible when such market discount is included in income, including upon the
sale, disposition, or repayment of the Security (or in the case of a
Pass-Through Security, an underlying Loan). A holder may elect to include market
discount in income currently as it accrues, on all market discount obligations
acquired by such holder during the taxable year such election is made and
thereafter, in which case the interest deferral rule will not apply.
 
     Premium.  A holder who purchases a Debt Security (other than an Interest
Weighted Security to the extent described above) at a cost greater than its
stated redemption price at maturity, generally will be considered to have
purchased the Security at a premium, which it may elect to amortize as an offset
to interest income on such
 
                                       76
 

<PAGE>
<PAGE>

Security (and not as a separate deduction item) on a constant yield method.
Although no regulations addressing the computation of premium accrual on
securities similar to the Securities have been issued, the legislative history
of the 1986 Act indicates that premium is to be accrued in the same manner as
market discount. Accordingly, it appears that the accrual of premium on a Class
of Pay-Through Securities will be calculated using the prepayment assumption
used in pricing such Class. If a holder makes an election to amortize premium on
a Debt Security, such election will apply to all taxable debt instruments
(including all REMIC regular interests and all pass-through certificates
representing ownership interests in a trust holding debt obligations) held by
the holder at the beginning of the taxable year in which the election is made,
and to all taxable debt instruments acquired thereafter by such holder, and will
be irrevocable without the consent of the IRS. Purchasers who pay a premium for
the Securities should consult their tax advisers regarding the election to
amortize premium and the method to be employed.
 
     On December 30, 1997 the IRS issued final regulations (the 'Amortizable
Bond Premium Regulations') dealing with amortizable bond premium. These
regulations specifically do not apply to prepayable debt instruments subject to
Code Section 1272(a)(6) such as the Securities. Absent further guidance from the
IRS, the Trustee intends to account for amortizable bond premium in the manner
described above. Prospective purchasers of the Securities should consult their
tax advisors regarding the possible application of the Amortizable Bond Premium
Regulations.
 
     Election to Treat All Interest as Original Issue Discount.  The OID
Regulations permit a holder of a Debt Security to elect to accrue all interest,
discount (including de minimis market or original issue discount) and premium in
income as interest, based on a constant yield method for Debt Securities
acquired on or after April 4, 1994. If such an election were to be made with
respect to a Debt Security with market discount, the holder of the Debt Security
would be deemed to have made an election to include in income currently market
discount with respect to all other debt instruments having market discount that
such holder of the Debt Security acquires during the year of the election or
thereafter. Similarly, a holder of a Debt Security that makes this election for
a Debt Security that is acquired at a premium will be deemed to have made an
election to amortize bond premium with respect to all debt instruments having
amortizable bond premium that such holder owns or acquires. The election to
accrue interest, discount and premium on a constant yield method with respect to
a Debt Security is irrevocable.
 
TAXATION OF THE REMIC AND ITS HOLDERS
 
     General.  In the opinion of Brown & Wood LLP, special counsel to the
Depositor, if a REMIC election is made with respect to a Series of Securities,
then the arrangement by which the Securities of that Series are issued will be
treated as a REMIC as long as all of the provisions of the applicable Agreement
are complied with and the statutory and regulatory requirements are satisfied.
Securities will be designated as 'Regular Interests' or 'Residual Interests' in
a REMIC, as specified in the related Prospectus Supplement.
 
     Except to the extent specified otherwise in a Prospectus Supplement, if a
REMIC election is made with respect to a Series of Securities, (i) Securities
held by a domestic building and loan association will constitute 'a regular or a
residual interest in a REMIC' within the meaning of Code Section
7701(a)(19)(C)(xi) (assuming that at least 95% of the REMIC's assets consist of
cash, government securities, 'loans secured by an interest in real property,'
and other types of assets described in Code Section 7701(a)(19)(C)); and (ii)
Securities held by a real estate investment trust will constitute 'real estate
assets' within the meaning of Code Section 856(c)(5)(B), and income with respect
to the Securities will be considered 'interest on obligations secured by
mortgages on real property or on interests in real property' within the meaning
of Code Section 856(c)(3)(B) (assuming, for both purposes, that at least 95% of
the REMIC's assets are qualifying assets). If less than 95% of the REMIC's
assets consist of assets described in (i) or (ii) above, then a Security will
qualify for the tax treatment described in (i), (ii) or (iii) in the proportion
that such REMIC assets are qualifying assets.
 
     The Small Business Job Protection Act of 1996, as part of the repeal of the
bad debt reserve method for thrift institutions, repealed the application of
Code Section 593(d) to any taxable year beginning after December 31, 1995.
 
                                       77

REMIC EXPENSES; SINGLE CLASS REMICS
 
     As a general rule, all of the expenses of a REMIC will be taken into
account by holders of the Residual Interest Securities. In the case of a 'single
class REMIC,' however, the expenses will be allocated, under Treasury
regulations, among the holders of the Regular Interest Securities and the
holders of the Residual Interest Securities (as defined herein) on a daily basis
in proportion to the relative amounts of income accruing to each Holder on that
day. In the case of a holder of a Regular Interest Security who is an individual
or a 'pass-through interest holder' (including certain pass-through entities but
not including real estate investment trusts), such expenses will be deductible
only to the extent that such expenses, plus other 'miscellaneous itemized
deductions' of the Holder, exceed 2% of such Holder's adjusted gross income. In
addition, for taxable years beginning after December 31, 1990, the amount of
itemized deductions otherwise allowable for the taxable year for an individual
whose adjusted gross income exceeds the applicable amount (which amount will be
adjusted for inflation for taxable years beginning after 1990) will be reduced
by the lesser of (i) 3% of the excess of adjusted gross income over the
applicable amount, or (ii) 80% of the amount of itemized deductions otherwise
allowable for such taxable year. The reduction or disallowance of this deduction
may have a significant impact on the yield of the Regular Interest Security to
such a Holder. In general terms, a single class REMIC is one that either (i)
would qualify, under existing Treasury regulations, as a grantor trust if it
were not a REMIC (treating all interests as ownership interests, even if they
would be classified as debt for federal income tax purposes) or (ii) is similar
to such a trust and which is structured with the principal purpose of avoiding
the single class REMIC rules. Unless otherwise specified in the related
Prospectus Supplement, the expenses of the REMIC will be allocated to holders of
the related residual interest securities.
 
TAXATION OF THE REMIC
 
     General.  Although a REMIC is a separate entity for federal income tax
purposes, a REMIC is not generally subject to entity-level tax. Rather, the
taxable income or net loss of a REMIC is taken into account by the holders of
residual interests. As described above, the regular interests are generally
taxable as debt of the REMIC.
 
     Calculation of REMIC Income.  The taxable income or net loss of a REMIC is
determined under an accrual method of accounting and in the same manner as in
the case of an individual, with certain adjustments. In general, the taxable
income or net loss will be the difference between (i) the gross income produced
by the REMIC's assets, including stated interest and any original issue discount
or market discount on loans and other assets, and (ii) deductions, including
stated interest and original issue discount accrued on Regular Interest
Securities, amortization of any premium with respect to Loans, and servicing
fees and other expenses of the REMIC. A holder of a Residual Interest Security
that is an individual or a 'pass-through interest holder' (including certain
pass-through entities, but not including real estate investment trusts) will be
unable to deduct servicing fees payable on the loans or other administrative
expenses of the REMIC for a given taxable year, to the extent that such
expenses, when aggregated with such holder's other miscellaneous itemized
deductions for that year, do not exceed two percent of such holder's adjusted
gross income.
 
     For purposes of computing its taxable income or net loss, the REMIC should
have an initial aggregate tax basis in its assets equal to the aggregate fair
market value of the regular interests and the residual interests on the Startup
Day (generally, the day that the interests are issued). That aggregate basis
will be allocated among the assets of the REMIC in proportion to their
respective fair market values.
 
     The OID provisions of the Code apply to loans of individuals originated on
or after March 2, 1984, and the market discount provisions apply to loans
originated after July 18, 1984. Subject to possible application of the de
minimis rules, the method of accrual by the REMIC of OID income on such loans
will be equivalent to the method under which holders of Pay-Through Securities
accrue original issue discount (i.e., under the constant yield method taking
into account the Prepayment Assumption). The REMIC will deduct OID on the
Regular Interest Securities in the same manner that the holders of the Regular
Interest Securities include such discount in income, but without regard to the
de minimis rules. See 'Taxation of Debt Securities' above. However, a REMIC that
acquires loans at a market discount must include such market discount in income
currently, as it accrues, on a constant interest basis.
 
     To the extent that the REMIC's basis allocable to loans that it holds
exceeds their principal amounts, the resulting premium, if attributable to
mortgages originated after September 27, 1985, will be amortized over the
 
                                       78
 

<PAGE>
<PAGE>

life of the loans (taking into account the Prepayment Assumption) on a constant
yield method. Although the law is somewhat unclear regarding recovery of premium
attributable to loans originated on or before such date, it is possible that
such premium may be recovered in proportion to payments of loan principal.
 
     Prohibited Transactions and Contributions Tax.  The REMIC will be subject
to a 100% tax on any net income derived from a 'prohibited transaction.' For
this purpose, net income will be calculated without taking into account any
losses from prohibited transactions or any deductions attributable to any
prohibited transaction that resulted in a loss. In general, prohibited
transactions include: (i) subject to limited exceptions, the sale or other
disposition of any qualified mortgage transferred to the REMIC; (ii) subject to
a limited exception, the sale or other disposition of a cash flow investment;
(iii) the receipt of any income from assets not permitted to be held by the
REMIC pursuant to the Code; or (iv) the receipt of any fees or other
compensation for services rendered by the REMIC. It is anticipated that a REMIC
will not engage in any prohibited transactions in which it would recognize a
material amount of net income. In addition, subject to a number of exceptions, a
tax is imposed at the rate of 100% on amounts contributed to a REMIC after the
close of the three-month period beginning on the Startup Day. The holders of
Residual Interest Securities will generally be responsible for the payment of
any such taxes imposed on the REMIC. To the extent not paid by such holders or
otherwise, however, such taxes will be paid out of the Trust Fund and will be
allocated pro rata to all outstanding classes of Securities of such REMIC.
 
TAXATION OF HOLDERS OF RESIDUAL INTEREST SECURITIES
 
     The holder of a Security representing a residual interest (a 'Residual
Interest Security') will take into account the 'daily portion' of the taxable
income or net loss of the REMIC for each day during the taxable year on which
such holder held the Residual Interest Security. The daily portion is determined
by allocating to each day in any calendar quarter its ratable portion of the
taxable income or net loss of the REMIC for such quarter, and by allocating that
amount among the holders (on such day) of the Residual Interest Securities in
proportion to their respective holdings on such day.
 
     The holder of a Residual Interest Security must report its proportionate
share of the taxable income of the REMIC whether or not it receives cash
distributions from the REMIC attributable to such income or loss. The reporting
of taxable income without corresponding distributions could occur, for example,
in certain REMIC issues in which the loans held by the REMIC were issued or
acquired at a discount, since mortgage prepayments cause recognition of discount
income, while the corresponding portion of the prepayment could be used in whole
or in part to make principal payments on REMIC Regular Interests issued without
any discount or at an insubstantial discount (if this occurs, it is likely that
cash distributions will exceed taxable income in later years). Taxable income
may also be greater in earlier years of certain REMIC issues as a result of the
fact that interest expense deductions, as a percentage of outstanding principal
on REMIC Regular Interest Securities, will typically increase over time as lower
yielding Securities are paid, whereas interest income with respect to loans will
generally remain constant over time as a percentage of loan principal.
 
     In any event, because the holder of a residual interest is taxed on the net
income of the REMIC, the taxable income derived from a Residual Interest
Security in a given taxable year will not be equal to the taxable income
associated with investment in a corporate bond or stripped instrument having
similar cash flow characteristics and pretax yield. Therefore, the after-tax
yield on the Residual Interest Security may be less than that of such a bond or
instrument.
 
     Limitation on Losses.  The amount of the REMIC's net loss that a holder may
take into account currently is limited to the holder's adjusted basis at the end
of the calendar quarter in which such loss arises. A holder's basis in a
Residual Interest Security will initially equal such holder's purchase price,
and will subsequently be increased by the amount of the REMIC's taxable income
allocated to the holder, and decreased (but not below zero) by the amount of
distributions made and the amount of the REMIC's net loss allocated to the
holder. Any disallowed loss may be carried forward indefinitely, but may be used
only to offset income of the REMIC generated by the same REMIC. The ability of
holders of Residual Interest Securities to deduct net losses may be subject to
additional limitations under the Code, as to which such holders should consult
their tax advisers.
 
     Distributions.  Distributions on a Residual Interest Security (whether at
their scheduled times or as a result of prepayments) will generally not result
in any additional taxable income or loss to a holder of a Residual Interest
Security. If the amount of such payment exceeds a holder's adjusted basis in the
Residual Interest
 
                                       79
 

<PAGE>
<PAGE>

Security, however, the holder will recognize gain (treated as gain from the sale
of the Residual Interest Security) to the extent of such excess.
 
     Sale or Exchange.  A holder of a Residual Interest Security will recognize
gain or loss on the sale or exchange of a Residual Interest Security equal to
the difference, if any, between the amount realized and such holder's adjusted
basis in the Residual Interest Security at the time of such sale or exchange.
Except to the extent provided in regulations, which have not yet been issued,
any loss upon disposition of a Residual Interest Security will be disallowed if
the selling holder acquires any residual interest in a REMIC or similar mortgage
pool within six months before or after such disposition.
 
     Excess Inclusions.  The portion of the REMIC taxable income of a holder of
a Residual Interest Security consisting of 'excess inclusion' income may not be
offset by other deductions or losses, including net operating losses, on such
holder's federal income tax return. Further, if the holder of a Residual
Interest Security is an organization subject to the tax on unrelated business
income imposed by Code Section 511, such holder's excess inclusion income will
be treated as unrelated business taxable income of such holder. In addition,
under Treasury regulations yet to be issued, if a real estate investment trust,
a regulated investment company, a common trust fund, or certain cooperatives
were to own a Residual Interest Security, a portion of dividends (or other
distributions) paid by the real estate investment trust (or other entity) would
be treated as excess inclusion income. If a Residual Security is owned by a
foreign person excess inclusion income is subject to tax at a rate of 30% which
may not be reduced by treaty, is not eligible for treatment as 'portfolio
interest' and is subject to certain additional limitations. See 'Tax Treatment
of Foreign Investors.' The Small Business Job Protection Act of 1996 has
eliminated the special rule permitting Section 593 institutions ('thrift
institutions') to use net operating losses and other allowable deductions to
offset their excess inclusion income from REMIC residual certificates that have
'significant value' within the meaning of the REMIC Regulations, effective for
taxable years beginning after December 31, 1995, except with respect to residual
certificates continuously held by a thrift institution since November 1, 1995.
 
     In addition, the Small Business Job Protection Act of 1996 provides three
rules for determining the effect on excess inclusions of the alternative minimum
taxable income of a residual holder. First, alternative minimum taxable income
for such residual holder is determined without regard to the special rule that
taxable income cannot be less than excess inclusions. Second, a residual
holder's alternative minimum taxable income for a tax year cannot be less than
excess inclusions for the year. Third, the amount of any alternative minimum tax
net operating loss deductions must be computed without regard to any excess
inclusions. These rules are effective for tax years beginning after December 31,
1986, unless a residual holder elects to have such rules apply only to tax years
beginning after August 20, 1996.
 
     The excess inclusion portion of a REMIC's income is generally equal to the
excess, if any, of REMIC taxable income for the quarterly period allocable to a
Residual Interest Security, over the daily accruals for such quarterly period of
(i) 120% of the long term applicable federal rate on the Startup Day multiplied
by (ii) the adjusted issue price of such Residual Interest Security at the
beginning of such quarterly period. The adjusted issue price of a Residual
Interest at the beginning of each calendar quarter will equal its issue price
(calculated in a manner analogous to the determination of the issue price of a
Regular Interest), increased by the aggregate of the daily accruals for prior
calendar quarters, and decreased (but not below zero) by the amount of loss
allocated to a holder and the amount of distributions made on the Residual
Interest Security before the beginning of the quarter. The long-term federal
rate, which is announced monthly by the Treasury Department, is an interest rate
that is based on the average market yield of outstanding marketable obligations
of the United States government having remaining maturities in excess of nine
years.
 
     Under the REMIC Regulations, in certain circumstances, transfers of
Residual Securities may be disregarded. See ' -- Restrictions on Ownership and
Transfer of Residual Interest Securities' and ' -- Tax Treatment of Foreign
Investors' below.
 
     Restrictions on Ownership and Transfer of Residual Interest Securities.  As
a condition to qualification as a REMIC, reasonable arrangements must be made to
prevent the ownership of a REMIC residual interest by any 'Disqualified
Organization.' Disqualified Organizations include the United States, any State
or political subdivision thereof, any foreign government, any international
organization, or any agency or instrumentality of any of the foregoing, a rural
electric or telephone cooperative described in Section 1381(a)(2)(C) of the
Code, or any entity exempt from the tax imposed by Sections 1-1399 of the Code,
if such entity is not subject to tax on its unrelated business income.
Accordingly, the applicable Pooling and Servicing Agreement will prohibit
 
                                       80
 

<PAGE>
<PAGE>

Disqualified Organizations from owning a Residual Interest Security. In
addition, no transfer of a Residual Interest Security will be permitted unless
the proposed transferee shall have furnished to the Trustee an affidavit
representing and warranting that it is neither a Disqualified Organization nor
an agent or nominee acting on behalf of a Disqualified Organization.
 
     If a Residual Interest Security is transferred to a Disqualified
Organization after March 31, 1988 (in violation of the restrictions set forth
above), a substantial tax can be imposed on the transferor of such Residual
Interest Security at the time of the transfer. In addition, if a Disqualified
Organization holds an interest in a pass-through entity after March 31, 1988
(including, among others, a partnership, trust, real estate investment trust,
regulated investment company, or any person holding as nominee), that owns a
Residual Interest Security, the pass-through entity will be required to pay an
annual tax on its allocable share of the excess inclusion income of the REMIC.
 
     For taxable years beginning after December 31, 1997, all partners of
certain electing partnerships having 100 or more partners ('electing large
partnerships') will be treated as Disqualified Organizations for purposes of the
tax imposed on pass-through entities if such electing large partnerships hold
Residual Interest Securities. However, the electing large partnership would be
entitled to exclude the excess inclusion income from gross income for purposes
of determining the taxable income of the partners.
 
     Under the REMIC Regulations, if a Residual Interest Security is a
'noneconomic residual interest,' as described below, a transfer of a Residual
Interest Security to a United States person will be disregarded for all Federal
tax purposes unless no significant purpose of the transfer was to impede the
assessment or collection of tax. A Residual Interest Security is a 'noneconomic
residual interest' unless, at the time of the transfer (i) the present value of
the expected future distributions on the Residual Interest Security at least
equals the product of the present value of the anticipated excess inclusions and
the highest rate of tax for the year in which the transfer occurs, and (ii) the
transferor reasonably expects that the transferee will receive distributions
from the REMIC at or after the time at which the taxes accrue on the anticipated
excess inclusions in an amount sufficient to satisfy the accrued taxes. If a
transfer of a Residual Interest is disregarded, the transferor would be liable
for any Federal income tax imposed upon taxable income derived by the transferee
from the REMIC. The REMIC Regulations provide no guidance as to how to determine
if a significant purpose of a transfer is to impede the assessment or collection
of tax. A similar type of limitation exists with respect to certain transfers of
residual interests by foreign persons to United States persons. See ' -- Tax
Treatment of Foreign Investors.'
 
     Mark to Market Rules.  Prospective purchasers of a REMIC Residual Interest
Security should be aware that a REMIC Residual Interest Security acquired after
January 3, 1995 cannot be marked-to-market.
 
ADMINISTRATIVE MATTERS
 
     The REMIC's books must be maintained on a calendar year basis and the REMIC
must file an annual federal income tax return. The REMIC will also be subject to
the procedural and administrative rules of the Code applicable to partnerships,
including the determination of any adjustments to, among other things, items of
REMIC income, gain, loss, deduction, or credit, by the IRS in a unified
administrative proceeding.
 
TAX STATUS AS A GRANTOR TRUST
 
     General.  As specified in the related Prospectus Supplement if a REMIC or
partnership election is not made, in the opinion of Brown & Wood LLP, special
counsel to the Depositor, the Trust Fund relating to a Series of Securities will
be classified for federal income tax purposes as a grantor trust under Subpart
E, Part I of Subchapter J of the Code and not as an association taxable as a
corporation (the Securities of such Series, 'Pass-Through Securities'). In some
Series there will be no separation of the principal and interest payments on the
Loans. In such circumstances, a Holder will be considered to have purchased a
pro rata undivided interest in each of the Loans. In other cases ('Stripped
Securities'), sale of the Securities will produce a separation in the ownership
of all or a portion of the principal payments from all or a portion of the
interest payments on the Loans.
 
     Each Holder must report on its federal income tax return its share of the
gross income derived from the Loans (not reduced by the amount payable as fees
to the Trustee and the Servicer and similar fees (collectively, the 'Servicing
Fee')), at the same time and in the same manner as such items would have been
reported under the Holder's tax accounting method had it held its interest in
the Loans directly, received directly its share of the
 
                                       81
 

<PAGE>
<PAGE>

amounts received with respect to the Loans, and paid directly its share of the
Servicing Fees. In the case of Pass-Through Securities other than Stripped
Securities, such income will consist of a pro rata share of all of the income
derived from all of the Loans and, in the case of Stripped Securities, such
income will consist of a pro rata share of the income derived from each stripped
bond or stripped coupon in which the Holder owns an interest. The holder of a
Security will generally be entitled to deduct such Servicing Fees under Section
162 or Section 212 of the Code to the extent that such Servicing Fees represent
'reasonable' compensation for the services rendered by the Trustee and the
Servicer (or third parties that are compensated for the performance of
services). In the case of a noncorporate holder, however, Servicing Fees (to the
extent not otherwise disallowed, e.g., because they exceed reasonable
compensation) will be deductible in computing such holder's regular tax
liability only to the extent that such fees, when added to other miscellaneous
itemized deductions, exceed 2% of adjusted gross income and may not be
deductible to any extent in computing such holder's alternative minimum tax
liability. In addition, for taxable years beginning after December 31, 1990, the
amount of itemized deductions otherwise allowable for the taxable year for an
individual whose adjusted gross income exceeds the applicable amount (which
amount will be adjusted for inflation in taxable years beginning after 1990)
will be reduced by the lesser of (i) 3% of the excess of adjusted gross income
over the applicable amount or (ii) 80% of the amount of itemized deductions
otherwise allowable for such taxable year. For taxable years beginning after
December 31, 1997, in the case of a partnership that has 100 or more partners
and elects to be treated as an 'electing large partnership,' 70 percent of such
partnership's miscellaneous itemized deductions will be disallowed, although the
remaining deductions will generally be allowed at the partnership level and will
not be subject to the 2 percent floor that would otherwise be applicable to
individual partners. Moreover, a Pass-Through Security Holder that is not a
corporation cannot deduct such expenses for purposes of the alternative minimum
tax (if applicable). An individiual's deductions may also limited by Code
Section 68 if the individual's adjusted gross income exdceeds certain limits.
Such deductions will include servicing, guarantee and administrative fees paid
to the servicer of the Loans. As a result, certain holders of Pass-Through
Securities may have taxable income in excess of the cash received.
 
     Discount or Premium on Pass-Through Securities.  The holder's purchase
price of a Pass-Through Security is to be allocated among the Loans in
proportion to their fair market values, determined as of the time of purchase of
the Securities. In the typical case, the Trustee (to the extent necessary to
fulfill its reporting obligations) will treat each Loan as having a fair market
value proportional to the share of the aggregate principal balances of all of
the Loans that it represents, since the Securities, unless otherwise specified
in the related Prospectus Supplement, will have a relatively uniform interest
rate and other common characteristics. To the extent that the portion of the
purchase price of a Pass-Through Security allocated to a Loan (other than to a
right to receive any accrued interest thereon and any undistributed principal
payments) is less than or greater than the portion of the principal balance of
the Loan allocable to the Security, the interest in the Loan allocable to the
Pass-Through Security will be deemed to have been acquired at a discount or
premium, respectively.
 
     The treatment of any discount will depend on whether the discount
represents OID or market discount. In the case of a Loan with OID in excess of a
prescribed de minimis amount or a Stripped Security, a holder of a Security will
be required to report as interest income in each taxable year its share of the
amount of OID that accrues during that year in the manner described above. OID
with respect to a Loan could arise, for example, by virtue of the financing of
points by the originator of the Loan, or by virtue of the charging of points by
the originator of the Loan in an amount greater than a statutory de minimis
exception, in circumstances under which the points are not currently deductible
pursuant to applicable Code provisions. Any market discount or premium on a Loan
will be includible in income, generally in the manner described above, except
that in the case of Pass-Through Securities, market discount is calculated with
respect to the Loans underlying the Certificate, rather than with respect to the
Security. A Holder that acquires an interest in a Loan originated after July 18,
1984 with more than a de minimis amount of market discount (generally, the
excess of the principal amount of the Loan over the purchaser's allocable
purchase price) will be required to include accrued market discount in income in
the manner set forth above. See ' -- Taxation of Debt Securities; Market
Discount' and ' -- Premium' above.
 
     In the case of market discount on a Pass-Through Security attributable to
Loans originated on or before July 18, 1984, the holder generally will be
required to allocate the portion of such discount that is allocable to a loan
among the principal payments on the Loan and to include the discount allocable
to each principal payment in ordinary income at the time such principal payment
is made. Such treatment would generally result in discount being included in
income at a slower rate than discount would be required to be included in income
using the method described in the preceding paragraph.
 
                                       82

     Stripped Securities.  A Stripped Security may represent a right to receive
only a portion of the interest payments on the Loans, a right to receive only
principal payments on the Loans, or a right to receive certain payments of both
interest and principal. Certain Stripped Securities ('Ratio Strip Securities')
may represent a right to receive differing percentages of both the interest and
principal on each Loan. Pursuant to Section 1286 of the Code, the separation of
ownership of the right to receive some or all of the interest payments on an
obligation from ownership of the right to receive some or all of the principal
payments results in the creation of 'stripped bonds' with respect to principal
payments and 'stripped coupons' with respect to interest payments. Section 1286
of the Code applies the OID rules to stripped bonds and stripped coupons. For
purposes of computing original issue discount, a stripped bond or a stripped
coupon is treated as a debt instrument issued on the date that such stripped
interest is purchased with an issue price equal to its purchase price or, if
more than one stripped interest is purchased, the ratable share of the purchase
price allocable to such stripped interest.
 
     Servicing fees in excess of reasonable servicing fees ('excess servicing')
will be treated under the stripped bond rules. If the excess servicing fee is
less than 100 basis points (i.e., 1% interest on the Loan principal balance) or
the Securities are initially sold with a de minimis discount (assuming no
prepayment assumption is required), any non-de minimis discount arising from a
subsequent transfer of the Securities should be treated as market discount. The
IRS appears to require that reasonable servicing fees be calculated on a Loan by
Loan basis, which could result in some Loans being treated as having more than
100 basis points of interest stripped off.
 
     The Code.  OID Regulations and judicial decisions provide no direct
guidance as to how the interest and original issue discount rules are to apply
to Stripped Securities and other Pass-Through Securities. Under the method
described above for Pay-Through Securities (the 'Cash Flow Bond Method'), a
prepayment assumption is used and periodic recalculations are made which take
into account with respect to each accrual period the effect of prepayments
during such period. However, the 1986 Act does not, absent Treasury regulations,
appear specifically to cover instruments such as the Stripped Securities which
technically represent ownership interests in the underlying Loans, rather than
being debt instruments 'secured by' those loans. For tax years beginning after
August 5, 1997 the Taxpayer Relief Act of 1997 may allow use of the Cash Flow
Bond Method with respect to Stripped Securities and other Pass-Through
Securities because it provides that such method applies to any pool of debt
instruments the yield on which may be affected by prepayments. Nevertheless, it
is believed that the Cash Flow Bond Method is a reasonable method of reporting
income for such Securities, and it is expected that OID will be reported on that
basis unless otherwise specified in the related Prospectus Supplement. In
applying the calculation to Pass-Through Securities, the Trustee will treat all
payments to be received by a holder with respect to the underlying Loans as
payments on a single installment obligation. The IRS could, however, assert that
original issue discount must be calculated separately for each Loan underlying a
Security.
 
     Under certain circumstances, if the Loans prepay at a rate faster than the
Prepayment Assumption, the use of the Cash Flow Bond Method may accelerate a
Holder's recognition of income. If, however, the Loans prepay at a rate slower
than the Prepayment Assumption, in some circumstances the use of this method may
decelerate a Holder's recognition of income.
 
     In the case of a Stripped Security that is an Interest Weighted Security,
the Trustee intends, absent contrary authority, to report income to Security
holders as OID, in the manner described above for Interest Weighted Securities.
 
     Possible Alternative Characterizations.  The characterizations of the
Stripped Securities described above are not the only possible interpretations of
the applicable Code provisions. Among other possibilities, the IRS could contend
that (i) in certain Series, each non-Interest Weighted Security is composed of
an unstripped undivided ownership interest in Loans and an installment
obligation consisting of stripped principal payments; (ii) the non-Interest
Weighted Securities are subject to the contingent payment provisions of the
Contingent Regulations; or (iii) each Interest Weighted Stripped Security is
composed of an unstripped undivided ownership interest in Loans and an
installment obligation consisting of stripped interest payments.
 
     Given the variety of alternatives for treatment of the Stripped Securities
and the different federal income tax consequences that result from each
alternative, potential purchasers are urged to consult their own tax advisers
regarding the proper treatment of the Securities for federal income tax
purposes.
 
                                       83

<PAGE>

     Character as Qualifying Loans.  In the case of Stripped Securities, there
is no specific legal authority existing regarding whether the character of the
Securities, for federal income tax purposes, will be the same as the Loans. The
IRS could take the position that the Loans' character is not carried over to the
Securities in such circumstances. Pass-Through Securities will be, and, although
the matter is not free from doubt, Stripped Securities should be considered to
represent 'real estate assets' within the meaning of Section 856(c)(5)(B) of the
Code and 'loans secured by an interest in real property' within the meaning of
Section 7701(a)(19)(C)(v) of the Code; and interest income attributable to the
Securities should be considered to represent 'interest on obligations secured by
mortgages on real property or on interests in real property' within the meaning
of Section 856(c)(3)(B) of the Code. Reserves or funds underlying the Securities
may cause a proportionate reduction in the above-described qualifying status
categories of Securities.
 
SALE OR EXCHANGE
 
     Subject to the discussion below with respect to Trust Funds as to which a
partnership election is made, a Holder's tax basis in its Security is the price
such holder pays for a Security, plus amounts of original issue or market
discount included in income and reduced by any payments received (other than
qualified stated interest payments) and any amortized premium. Gain or loss
recognized on a sale, exchange, or redemption of a Security, measured by the
difference between the amount realized and the Security's basis as so adjusted,
will generally be capital gain or loss, assuming that the Security is held as a
capital asset. In the case of a Security held by a bank, thrift, or similar
institution described in Section 582 of the Code, however, gain or loss realized
on the sale or exchange of a Regular Interest Security will be taxable as
ordinary income or loss. In addition, gain from the disposition of a Regular
Interest Security that might otherwise be capital gain will be treated as
ordinary income to the extent of the excess, if any, of (i) the amount that
would have been includible in the holder's income if the yield on such Regular
Interest Security had equaled 110% of the applicable federal rate as of the
beginning of such holder's holding period, over the amount of ordinary income
actually recognized by the holder with respect to such Regular Interest
Security. In general, the maximum tax rate on ordinary income for individual
taxpayers is 39.6% and the maximum tax rate on long-term capital gains for such
taxpayers is 28%. The maximum tax rate on both ordinary income and long-term
capital gains of corporate taxpayers is 35%.
 
     The Taxpayer Relief Act of 1997 reduces the maximum rates on long-term
capital gains recognized on capital assets held by individual taxpayers for more
than eighteen months as of the date of disposition (and would further reduce the
maximum rates on such gains in the year 2001 and thereafter for certain
individual taxpayers who meet specified conditions). Prospective investors
should consult their own tax advisors concerning these tax law changes.
 
MISCELLANEOUS TAX ASPECTS
 
     Backup Withholding.  Subject to the discussion below with respect to Trust
Funds as to which a partnership election is made, a Holder, other than a holder
of a REMIC Residual Security, may, under certain circumstances, be subject to
'backup withholding' at a rate of 31% with respect to distributions or the
proceeds of a sale of certificates to or through brokers that represent interest
or original issue discount on the Securities. This withholding generally applies
if the holder of a Security (i) fails to furnish the Trustee with its taxpayer
identification number ('TIN'); (ii) furnishes the Trustee an incorrect TIN;
(iii) fails to report properly interest, dividends or other 'reportable
payments' as defined in the Code; or (iv) under certain circumstances, fails to
provide the Trustee or such holder's securities broker with a certified
statement, signed under penalty of perjury, that the TIN provided is its correct
number and that the holder is not subject to backup withholding. Backup
withholding will not apply, however, with respect to certain payments made to
Holders, including payments to certain exempt recipients (such as exempt
organizations) and to certain Nonresidents (as defined below). Holders should
consult their tax advisers as to their qualification for exemption from backup
withholding and the procedure for obtaining the exemption.
 
     Treasury regulations (the 'Final Withholding Regulations'), which are
generally effective with respect to payments made after December 31, 1999,
consolidate and modify the current requirements and means by which a holder may
claim exemptions from United States federal income tax withholding and provide
certain presumptious regarding the status of holders when payments to the
holders cannot be reliably associated documentation provided to the payor. All
holders should consult their tax advisors regarding the application of the Final
Withholding Regulations.

     The Trustee will report to the Holders and to the Servicer for each
calendar year the amount of any 'reportable payments' during such year and the
amount of tax withheld, if any, with respect to payments on the Securities.
 
TAX TREATMENT OF FOREIGN INVESTORS
 
     Subject to the discussion below with respect to Trust Funds as to which a
partnership election is made, under the Code, unless interest (including OID)
paid on a Security (other than a Residual Interest Security) is considered to be
'effectively connected' with a trade or business conducted in the United States
by a nonresident alien individual, foreign partnership or foreign corporation
('Nonresidents'), such interest will normally qualify as portfolio interest
(except where (i) the recipient is a holder, directly or by attribution, of 10%
or more of the capital or profits interest in the issuer, or (ii) the recipient
is a controlled foreign corporation to which the issuer is a related person) and
will be exempt from federal income tax. Upon receipt of appropriate ownership
statements, the issuer normally will be relieved of obligations to withhold tax
from such interest payments. These provisions supersede the generally applicable
provisions of United States law that would otherwise require the issuer to
withhold at a 30% rate (unless such rate were reduced or eliminated by an
applicable tax treaty) on, among other things, interest and other fixed or
determinable, annual or periodic income paid to Nonresidents. Holders of
Pass-Through Securities and Stripped Securities, including Ratio Strip
Securities, however, may be subject to withholding to the extent that the Loans
were originated on or before July 18, 1984.
 
     Interest and OID of Holders who are foreign persons are not subject to
withholding if they are effectively connected with a United States business
conducted by the Holder. They will, however, generally be subject to the regular
United States income tax.
 
     The Final Withholding Regulations consolidate and modify the current
certification requirements and means by which a non-United States person may
claim exemption from United States federal income tax withholding. All Foreign
Investors should consult their tax advisors regarding the application of the
Final Withholding Regulations, which are generally effective with respect to
payments made after December 31, 1999.
 
     Payments to holders of Residual Interest Securities who are foreign persons
will generally be treated as interest for purposes of the 30% (or lower treaty
rate) United States withholding tax. Holders should assume that such income does
not qualify for exemption from United States withholding tax as 'portfolio
interest.' It is clear that, to the extent that a payment represents a portion
of REMIC taxable income that constitutes excess inclusion income, a holder of a
Residual Interest Security will not be entitled to an exemption from or
reduction of the 30% (or lower treaty rate) withholding tax rule. If the
payments are subject to United States withholding tax, they generally will be
taken into account for withholding tax purposes only when paid or distributed
(or when the Residual Interest Security is disposed of). The Treasury has
statutory authority, however, to promulgate regulations which would require such
amounts to be taken into account at an earlier time in order to prevent the
avoidance of tax. Such regulations could, for example, require withholding prior
to the distribution of cash in the case of Residual Interest Securities that do
not have significant value. Under the REMIC Regulations, if a Residual Interest
Security has tax avoidance potential, a transfer of a Residual Interest Security
to a Nonresident will be disregarded for all federal tax purposes. A Residual
Interest Security has tax avoidance potential unless, at the time of the
transfer the transferor reasonably expects that the REMIC will distribute to the
transferee residual interest holder amounts that will equal at least 30% of each
excess inclusion, and that such amounts will be distributed at or after the time
at which the excess inclusions accrue and not later than the calendar year
following the calendar year of accrual. If a Nonresident transfers a Residual
Interest Security to a United States person, and if the transfer has the effect
of allowing the transferor to avoid tax on accrued excess inclusions, then the
transfer is disregarded and the transferor continues to be treated as the owner
of the Residual Interest Security for purposes of the withholding tax provisions
of the Code. See ' -- Excess Inclusions.'
 
TAX CHARACTERIZATION OF THE TRUST FUND AS A PARTNERSHIP
 
     Brown & Wood LLP, special counsel to the Depositor, will deliver its
opinion that a Trust Fund for which a partnership election is made will not be
an association (or publicly traded partnership) taxable as a corporation for
federal income tax purposes. This opinion will be based on the assumption that
the terms of the Trust Agreement and related documents will be complied with,
and on counsel's conclusions that the nature of the
 
                                       85
 

<PAGE>
<PAGE>

income of the Trust Fund will exempt it from the rule that certain publicly
traded partnerships are taxable as corporations or the issuance of the
Securities has been structured as a private placement under an IRS safe harbor,
so that the Trust Fund will not be characterized as a publicly traded
partnership taxable as a corporation.
 
     If the Trust Fund were taxable as a corporation for federal income tax
purposes, the Trust Fund would be subject to corporate income tax on its taxable
income. The Trust Fund's taxable income would include all its income, possibly
reduced by its interest expense on the Notes. Any such corporate income tax
could materially reduce cash available to make payments on the Notes and
distributions on the Certificates, and Certificateholders could be liable for
any such tax that is unpaid by the Trust Fund.
 
TAX CONSEQUENCES TO HOLDERS OF THE NOTES
 
     Treatment of the Notes as Indebtedness.  The Trust Fund will agree, and the
Noteholders will agree by their purchase of Notes, to treat the Notes as debt
for federal income tax purposes. Special counsel to the Depositor will, except
as otherwise provided in the related Prospectus Supplement, advise the Depositor
that the Notes will be classified as debt for federal income tax purposes. The
discussion below assumes this characterization of the Notes is correct.
 
     OID, Indexed Securities, etc.  The discussion below assumes that all
payments on the Notes are denominated in U.S. dollars, and that the Notes are
not Indexed Securities or Strip Notes. Moreover, the discussion assumes that the
interest formula for the Notes meets the requirements for 'qualified stated
interest' under the OID regulations, and that any OID on the Notes (i.e., any
excess of the principal amount of the Notes over their issue price) does not
exceed a de minimis amount (i.e., 0.25% of their principal amount multiplied by
the number of full years included in their term), all within the meaning of the
OID regulations. If these conditions are not satisfied with respect to any given
series of Notes, additional tax considerations with respect to such Notes will
be disclosed in the applicable Prospectus Supplement.
 
     Interest Income on the Notes.  Based on the above assumptions, except as
discussed in the following paragraph, the Notes will not be considered issued
with OID. The stated interest thereon will be taxable to a Noteholder as
ordinary interest income when received or accrued in accordance with such
Noteholder's method of tax accounting. Under the OID regulations, a holder of a
Note issued with a de minimis amount of OID must include such OID in income, on
a pro rata basis, as principal payments are made on the Note. It is believed
that any prepayment premium paid as a result of a mandatory redemption will be
taxable as contingent interest when it becomes fixed and unconditionally
payable. A purchaser who buys a Note for more or less than its principal amount
will generally be subject, respectively, to the premium amortization or market
discount rules of the Code.
 
     A holder of a Note that has a fixed maturity date of not more than one year
from the issue date of such Note (a 'Short-Term Note') may be subject to special
rules. An accrual basis holder of a Short-Term Note (and certain cash method
holders, including regulated investment companies, as set forth in Section 1281
of the Code) generally would be required to report interest income as interest
accrues on a straight-line basis over the term of each interest period. Other
cash basis holders of a Short-Term Note would, in general, be required to report
interest income as interest is paid (or, if earlier, upon the taxable
disposition of the Short-Term Note). However, a cash basis holder of a
Short-Term Note reporting interest income as it is paid may be required to defer
a portion of any interest expense otherwise deductible on indebtedness incurred
to purchase or carry the Short-Term Note until the taxable disposition of the
Short-Term Note. A cash basis taxpayer may elect under Section 1281 of the Code
to accrue interest income on all nongovernment debt obligations with a term of
one year or less, in which case the taxpayer would include interest on the
Short-Term Note in income as it accrues, but would not be subject to the
interest expense deferral rule referred to in the preceding sentence. Certain
special rules apply if a Short-Term Note is purchased for more or less than its
principal amount.
 
     Sale or Other Disposition.  If a Noteholder sells a Note, the holder will
recognize gain or loss in an amount equal to the difference between the amount
realized on the sale and the holder's adjusted tax basis in the Note. The
adjusted tax basis of a Note to a particular Noteholder will equal the holder's
cost for the Note, increased by any market discount, acquisition discount, OID
and gain previously included by such Noteholder in income with respect to the
Note and decreased by the amount of bond premium (if any) previously amortized
and by the amount of principal payments previously received by such Noteholder
with respect to such Note. Any such gain or loss will be capital gain or loss if
the Note was held as a capital asset, except for gain
 
                                       86
 

<PAGE>
<PAGE>

representing accrued interest and accrued market discount not previously
included in income. Capital losses generally may be used only to offset capital
gains.
 
     Foreign Holders.  Interest payments made (or accrued) to a Noteholder who
is a nonresident alien, foreign corporation or other non-United States person (a
'foreign person') generally will be considered 'portfolio interest', and
generally will not be subject to United States federal income tax and
withholding tax, if the interest is not effectively connected with the conduct
of a trade or business within the United States by the foreign person and the
foreign person (i) is not actually or constructively a '10 percent shareholder'
of the Trust Fund or the Seller (including a holder of 10% of the outstanding
Certificates) or a 'controlled foreign corporation' with respect to which the
Trust Fund or the Seller is a 'related person' within the meaning of the Code
and (ii) provides the Owner Trustee or other person who is otherwise required to
withhold U.S. tax with respect to the Notes with an appropriate statement (on
Form W-8 or a similar form), signed under penalties of perjury, certifying that
the beneficial owner of the Note is a foreign person and providing the foreign
person's name and address. If a Note is held through a securities clearing
organization or certain other financial institutions, the organization or
institution may provide the relevant signed statement to the withholding agent;
in that case, however, the signed statement must be accompanied by a Form W-8 or
substitute form provided by the foreign person that owns the Note. If such
interest is not portfolio interest, then it will be subject to United States
federal income and withholding tax at a rate of 30 percent, unless reduced or
eliminated pursuant to an applicable tax treaty.
 
     Any capital gain realized on the sale, redemption, retirement or other
taxable disposition of a Note by a foreign person will be exempt from United
States federal income and withholding tax, provided that (i) such gain is not
effectively connected with the conduct of a trade or business in the United
States by the foreign person and (ii) in the case of an individual foreign
person, the foreign person is not present in the United States for 183 days or
more in the taxable year.
 
     Backup Withholding.  Each holder of a Note (other than an exempt holder
such as a corporation, tax-exempt organization, qualified pension and
profit-sharing trust, individual retirement account or nonresident alien who
provides certification as to status as a nonresident) will be required to
provide, under penalties of perjury, a certificate containing the holder's name,
address, correct federal taxpayer identification number and a statement that the
holder is not subject to backup withholding. Should a nonexempt Noteholder fail
to provide the required certification, the Trust Fund will be required to
withhold 31 percent of the amount otherwise payable to the holder, and remit the
withheld amount to the IRS as a credit against the holder's federal income tax
liability.
 
     Possible Alternative Treatments of the Notes.  If, contrary to the opinion
of special counsel to the Company, the IRS successfully asserted that one or
more of the Notes did not represent debt for federal income tax purposes, the
Notes might be treated as equity interests in the Trust Fund. If so treated, the
Trust Fund might be taxable as a corporation with the adverse consequences
described above (and the taxable corporation would not be able to reduce its
taxable income by deductions for interest expense on Notes recharacterized as
equity). Alternatively, and most likely in the view of special counsel to the
Depositor, the Trust Fund might be treated as a publicly traded partnership that
would not be taxable as a corporation because it would meet certain qualifying
income tests. Nonetheless, treatment of the Notes as equity interests in such a
publicly traded partnership could have adverse tax consequences to certain
holders. For example, income to certain tax-exempt entities (including pension
funds) would be 'unrelated business taxable income', income to foreign holders
generally would be subject to U.S. tax and U.S. tax return filing and
withholding requirements, and individual holders might be subject to certain
limitations on their ability to deduct their share of the Trust Fund's expenses.
 
TAX CONSEQUENCES TO HOLDERS OF THE CERTIFICATES
 
     Treatment of the Trust Fund as a Partnership.  The Trust Fund and the
Master Servicer will agree, and the Certificateholders will agree by their
purchase of Certificates, to treat the Trust Fund as a partnership for purposes
of federal and state income tax, franchise tax and any other tax measured in
whole or in part by income, with the assets of the partnership being the assets
held by the Trust Fund, the partners of the partnership being the
Certificateholders, and the Notes being debt of the partnership. However, the
proper characterization of the arrangement involving the Trust Fund, the
Certificates, the Notes, the Trust Fund and the Servicer is not clear because
there is no authority on transactions closely comparable to that contemplated
herein.
 
                                       87
 

<PAGE>
<PAGE>

     A variety of alternative characterizations are possible.  For example,
because the Certificates have certain features characteristic of debt, the
Certificates might be considered debt of the Trust Fund. Any such
characterization would not result in materially adverse tax consequences to
Certificateholders as compared to the consequences from treatment of the
Certificates as equity in a partnership, described below. The following
discussion assumes that the Certificates represent equity interests in a
partnership.
 
     Indexed Securities, etc.  The following discussion assumes that all
payments on the Certificates are denominated in U.S. dollars, none of the
Certificates are Indexed Securities or Strip Certificates, and that a Series of
Securities includes a single class of Certificates. If these conditions are not
satisfied with respect to any given Series of Certificates, additional tax
considerations with respect to such Certificates will be disclosed in the
applicable Prospectus Supplement.
 
     Partnership Taxation.  As a partnership, the Trust Fund will not be subject
to federal income tax. Rather, each Certificateholder will be required to
separately take into account such holder's allocated share of income, gains,
losses, deductions and credits of the Trust Fund. The Trust Fund's income will
consist primarily of interest and finance charges earned on the Loans (including
appropriate adjustments for market discount, OID and bond premium) and any gain
upon collection or disposition of Loans. The Trust Fund's deductions will
consist primarily of interest accruing with respect to the Notes, servicing and
other fees, and losses or deductions upon collection or disposition of Loans.
 
     The tax items of a partnership are allocable to the partners in accordance
with the Code, Treasury regulations and the partnership agreement (here, the
Trust Agreement and related documents). The Trust Agreement will provide, in
general, that the Certificateholders will be allocated taxable income of the
Trust Fund for each month equal to the sum of (i) the interest that accrues on
the Certificates in accordance with their terms for such month, including
interest accruing at the Pass-Through Rate for such month and interest on
amounts previously due on the Certificates but not yet distributed; (ii) any
Trust Fund income attributable to discount on the Loans that corresponds to any
excess of the principal amount of the Certificates over their initial issue
price (iii) prepayment premium payable to the Certificateholders for such month;
and (iv) any other amounts of income payable to the Certificateholders for such
month. Such allocation will be reduced by any amortization by the Trust Fund of
premium on Loans that corresponds to any excess of the issue price of
Certificates over their principal amount. All remaining taxable income of the
Trust Fund will be allocated to the Company. Based on the economic arrangement
of the parties, this approach for allocating Trust Fund income should be
permissible under applicable Treasury regulations, although no assurance can be
given that the IRS would not require a greater amount of income to be allocated
to Certificateholders. Moreover, even under the foregoing method of allocation,
Certificateholders may be allocated income equal to the entire Pass-Through Rate
plus the other items described above even though the Trust Fund might not have
sufficient cash to make current cash distributions of such amount. Thus, cash
basis holders will in effect be required to report income from the Certificates
on the accrual basis and Certificateholders may become liable for taxes on Trust
Fund income even if they have not received cash from the Trust Fund to pay such
taxes. In addition, because tax allocations and tax reporting will be done on a
uniform basis for all Certificateholders but Certificateholders may be
purchasing Certificates at different times and at different prices,
Certificateholders may be required to report on their tax returns taxable income
that is greater or less than the amount reported to them by the Trust Fund.
 
     All of the taxable income allocated to a Certificateholder that is a
pension, profit sharing or employee benefit plan or other tax-exempt entity
(including an individual retirement account) will constitute 'unrelated business
taxable income' generally taxable to such a holder under the Code.
 
     An individual taxpayer's share of expenses of the Trust Fund (including
fees to the Servicer but not interest expense) would be miscellaneous itemized
deductions. Such deductions might be disallowed to the individual in whole or in
part and might result in such holder being taxed on an amount of income that
exceeds the amount of cash actually distributed to such holder over the life of
the Trust Fund.
 
     The Trust Fund intends to make all tax calculations relating to income and
allocations to Certificateholders on an aggregate basis. If the IRS were to
require that such calculations be made separately for each Loan, the Trust Fund
might be required to incur additional expense but it is believed that there
would not be a material adverse effect on Certificateholders.
 
                                       88
 

<PAGE>
<PAGE>

     Discount and Premium.  It is believed that the Loans were not issued with
OID, and, therefore, the Trust Fund should not have OID income. However, the
purchase price paid by the Trust Fund for the Loans may be greater or less than
the remaining principal balance of the Loans at the time of purchase. If so, the
Loan will have been acquired at a premium or discount, as the case may be. (As
indicated above, the Trust Fund will make this calculation on an aggregate
basis, but might be required to recompute it on a Loan by Loan basis.)
 
     If the Trust Fund acquires the Loans at a market discount or premium, the
Trust Fund will elect to include any such discount in income currently as it
accrues over the life of the Loans or to offset any such premium against
interest income on the Loans. As indicated above, a portion of such market
discount income or premium deduction may be allocated to Certificateholders.
 
     Section 708 Termination.  Pursuant to final regulations issued on May 9,
1997 under Code Section 708, a sale or exchange of 50% or more of the capital
and profits in a partnership would cause a deemed contribution of assets of the
partnership (the 'old partnership') to a new partnership (the 'new partnership')
in exchange for interests in the new partnership. Such interests would be deemed
distributed to the partners of the old partnership in liquidation thereof, which
would not constitute a sale or exchange. Accordingly under these new
regulations, if the Trust Fund were characterized as a partnership and a sale of
Certificates terminated the partnership under Code Section 708, the purchaser's
basis in its ownership interest would not change.
 
     Disposition of Certificates.  Generally, capital gain or loss will be
recognized on a sale of Certificates in an amount equal to the difference
between the amount realized and the seller's tax basis in the Certificates sold.
A Certificateholder's tax basis in a Certificate will generally equal the
holder's cost increased by the holder's share of Trust Fund income (includible
in income) and decreased by any distributions received with respect to such
Certificate. In addition, both the tax basis in the Certificates and the amount
realized on a sale of a Certificate would include the holder's share of the
Notes and other liabilities of the Trust Fund. A holder acquiring Certificates
at different prices may be required to maintain a single aggregate adjusted tax
basis in such Certificates, and, upon sale or other disposition of some of the
Certificates, allocate a portion of such aggregate tax basis to the Certificates
sold (rather than maintaining a separate tax basis in each Certificate for
purposes of computing gain or loss on a sale of that Certificate).
 
     Any gain on the sale of a Certificate attributable to the holder's share of
unrecognized accrued market discount on the Loans would generally be treated as
ordinary income to the holder and would give rise to special tax reporting
requirements. The Trust Fund does not expect to have any other assets that would
give rise to such special reporting requirements. Thus, to avoid those special
reporting requirements, the Trust Fund will elect to include market discount in
income as it accrues.
 
     If a Certificateholder is required to recognize an aggregate amount of
income (not including income attributable to disallowed itemized deductions
described above) over the life of the Certificates that exceeds the aggregate
cash distributions with respect thereto, such excess will generally give rise to
a capital loss upon the retirement of the Certificates.
 
     Allocations Between Transferors and Transferees.  In general, the Trust
Fund's taxable income and losses will be determined monthly and the tax items
for a particular calendar month will be apportioned among the Certificateholders
in proportion to the principal amount of Certificates owned by them as of the
close of the last day of such month. As a result, a holder purchasing
Certificates may be allocated tax items (which will affect its tax liability and
tax basis) attributable to periods before the actual transaction.
 
     The use of such a monthly convention may not be permitted by existing
regulations. If a monthly convention is not allowed (or only applies to
transfers of less than all of the partner's interest), taxable income or losses
of the Trust Fund might be reallocated among the Certificateholders. The Trust
Fund's method of allocation between transferors and transferees may be revised
to conform to a method permitted by future regulations.
 
     Section 754 Election.  In the event that a Certificateholder sells its
Certificates at a profit (loss), the purchasing Certificateholder will have a
higher (lower) basis in the Certificates than the selling Certificateholder had.
The tax basis of the Trust Fund's assets will not be adjusted to reflect that
higher (or lower) basis unless the Trust Fund were to file an election under
Section 754 of the Code. In order to avoid the administrative complexities that
would be involved in keeping accurate accounting records, as well as potentially
onerous information reporting requirements, the Trust Fund will not make such
election. As a result, Certificateholders
 
                                       89
 

<PAGE>
<PAGE>

might be allocated a greater or lesser amount of Trust Fund income than would be
appropriate based on their own purchase price for Certificates.
 
     Administrative Matters.  The Owner Trustee is required to keep or have kept
complete and accurate books of the Trust Fund. Such books will be maintained for
financial reporting and tax purposes on an accrual basis and the fiscal year of
the Trust Fund will be the calendar year. The Trustee will file a partnership
information return (IRS Form 1065) with the IRS for each taxable year of the
Trust Fund and will report each Certificateholder's allocable share of items of
Trust Fund income and expense to holders and the IRS on Schedule K-1. The Trust
Fund will provide the Schedule K-l information to nominees that fail to provide
the Trust Fund with the information statement described below and such nominees
will be required to forward such information to the beneficial owners of the
Certificates. Generally, holders must file tax returns that are consistent with
the information return filed by the Trust Fund or be subject to penalties unless
the holder notifies the IRS of all such inconsistencies.
 
     Under Section 6031 of the Code, any person that holds Certificates as a
nominee at any time during a calendar year is required to furnish the Trust Fund
with a statement containing certain information on the nominee, the beneficial
owners and the Certificates so held. Such information includes (i) the name,
address and taxpayer identification number of the nominee and (ii) as to each
beneficial owner (x) the name, address and identification number of such person,
(y) whether such person is a United States person, a tax-exempt entity or a
foreign government, an international organization, or any wholly owned agency or
instrumentality of either of the foregoing, and (z) certain information on
Certificates that were held, bought or sold on behalf of such person throughout
the year. In addition, brokers and financial institutions that hold Certificates
through a nominee are required to furnish directly to the Trust Fund information
as to themselves and their ownership of Certificates. A clearing agency
registered under Section 17A of the Exchange Act is not required to furnish any
such information statement to the Trust Fund. The information referred to above
for any calendar year must be furnished to the Trust Fund on or before the
following January 31. Nominees, brokers and financial institutions that fail to
provide the Trust Fund with the information described above may be subject to
penalties.
 
     The Depositor will be designated as the tax matters partner in the related
Trust Agreement and, as such, will be responsible for representing the
Certificateholders in any dispute with the IRS. The Code provides for
administrative examination of a partnership as if the partnership were a
separate and distinct taxpayer. Generally, the statute of limitations for
partnership items does not expire before three years after the date on which the
partnership information return is filed. Any adverse determination following an
audit of the return of the Trust Fund by the appropriate taxing authorities
could result in an adjustment of the returns of the Certificateholders, and,
under certain circumstances, a Certificateholder may be precluded from
separately litigating a proposed adjustment to the items of the Trust Fund. An
adjustment could also result in an audit of a Certificateholder's returns and
adjustments of items not related to the income and losses of the Trust Fund.
 
     Tax Consequences to Foreign Certificateholders.  It is not clear whether
the Trust Fund would be considered to be engaged in a trade or business in the
United States for purposes of federal withholding taxes with respect to non-U.S.
Persons because there is no clear authority dealing with that issue under facts
substantially similar to those described herein. Although it is not expected
that the Trust Fund would be engaged in a trade or business in the United States
for such purposes, the Trust Fund will withhold as if it were so engaged in
order to protect the Trust Fund from possible adverse consequences of a failure
to withhold. The Trust Fund expects to withhold on the portion of its taxable
income, as calculated for this purpose which may exceed the distributions to
Certificateholders, that is allocable to foreign Certificateholders pursuant to
Section 1446 of the Code, as if such income were effectively connected to a U.S.
trade or business, at a rate of 35% for foreign holders that are taxable as
corporations and 39.6% for all other foreign holders. Subsequent adoption of
Treasury regulations or the issuance of other administrative pronouncements may
require the Trust Fund to change its withholding procedures. In determining a
holder's withholding status, the Trust Fund may rely on IRS Form W-8, IRS Form
W-9 or the holder's certification of nonforeign status signed under penalties of
perjury.
 
     The term 'U.S. Person' means a citizen or resident of the United States, a
corporation, partnership or other entity created or organized in or under the
laws of the United States or any state thereof or the District of Columbia
(other than a partnership that is not treated as a United States person under
any applicable Treasury regulations), or an estate whose income is subject to
U.S. federal income tax regardless of its source of income, or a trust if a
court within the United States is able to exercise primary supervision of the
administration of the trust and one or more United States persons have the
authority to control all substantial decisions of the trust.

Notwithstanding the preceding sentence, to the extent provided in regulations,
certain trusts in existence on August 20, 1996 and treated as United States
persons prior to such date that elect to continue to be so treated also shall be
considered U.S. Persons.
 
     Each foreign holder might be required to file a U.S. individual or
corporate income tax return (including, in the case of a corporation, the branch
profits tax) on its share of the Trust Fund's income. Each foreign holder must
obtain a taxpayer identification number from the IRS and submit that number to
the Trust Fund on Form W-8 in order to assure appropriate crediting of the taxes
withheld. A foreign holder generally would be entitled to file with the IRS a
claim for refund with respect to taxes withheld by the Trust Fund taking the
position that no taxes were due because the Trust Fund was not engaged in a U.S.
trade or business. However, interest payments made (or accrued) to a
Certificateholder who is a foreign person generally will be considered
guaranteed payments to the extent such payments are determined without regard to
the income of the Trust Fund. If these interest payments are properly
characterized as guaranteed payments, then the interest will not be considered
'portfolio interest.' As a result, Certificateholders will be subject to United
States federal income tax and withholding tax at a rate of 30 percent, unless
reduced or eliminated pursuant to an applicable treaty. In such case, a foreign
holder would only be entitled to claim a refund for that portion of the taxes in
excess of the taxes that should be withheld with respect to the guaranteed
payments.
 
     Backup Withholding.  Distributions made on the Certificates and proceeds
from the sale of the Certificates will be subject to a 'backup' withholding tax
of 31% if, in general, the Certificateholder fails to comply with certain
identification procedures, unless the holder is an exempt recipient under
applicable provisions of the Code.
 
                            STATE TAX CONSIDERATIONS
 
     In addition to the federal income tax consequences described in 'Federal
Income Tax Consequences,' potential investors should consider the state and
local income tax consequences of the acquisition, ownership, and disposition of
the Securities. State and local income tax law may differ substantially from the
corresponding federal law, and this discussion does not purport to describe any
aspect of the income tax laws of any state or locality. Therefore, potential
investors should consult their own tax advisors with respect to the various
state and local tax consequences of an investment in the Securities.
 
                              ERISA CONSIDERATIONS
 
     The following describes certain considerations under ERISA and the Code,
which apply only to Securities of a Series that are not divided into subclasses.
If Securities are divided into subclasses the related Prospectus Supplement will
contain information concerning considerations relating to ERISA and the Code
that are applicable to such Securities.
 
     ERISA imposes requirements on employee benefit plans subject to ERISA (and
the Code imposes requirements on certain other retirement plans and
arrangements, including individual retirement accounts and annuities, Keogh
plans and collective investment funds and separate accounts in which such plans,
accounts or arrangements are invested) (collectively 'Plans') and on persons who
are fiduciaries with respect to such Plans. Among other things, ERISA requires
that the assets of Plans be held in trust and that the trustee, or other duly
authorized fiduciary, have exclusive authority and discretion to manage and
control the assets of such Plans. ERISA also imposes certain duties on persons
who are fiduciaries of Plans. Under ERISA, any person who exercises any
authority or control respecting the management or disposition of the assets of a
Plan is considered to be a fiduciary of such Plan (subject to certain exceptions
not here relevant). Certain employee benefit plans, such as governmental plans
(as defined in ERISA Section 3(32)) and, if no election has been made under
Section 410(d) of the Code, church plans (as defined in ERISA Section 3(33)),
are not subject to ERISA requirements. Accordingly, assets of such plans may be
invested in Securities without regard to the ERISA considerations described
above and below, subject to the provisions of applicable state law. Any such
plan which is qualified and exempt from taxation under Code Sections 401(a) and
501(a), however, is subject to the prohibited transaction rules set forth in
Code Section 503.
 
     On November 13, 1986, the United States Department of Labor (the 'DOL')
issued final regulations concerning the definition of what constitutes the
assets of a Plan. (Labor Reg. Section 2510.3-101) Under this regulation, the
underlying assets and properties of corporations, partnerships and certain other
entities in which a
 
                                       91

<PAGE>

Plan makes an 'equity' investment could be deemed for purposes of ERISA to be
assets of the investing Plan in certain circumstances. However, the regulation
provides that, generally, the assets of a corporation or partnership in which a
Plan invests will not be deemed for purposes of ERISA to be assets of such Plan
if the equity interest acquired by the investing Plan is a publicly-offered
security. A publicly-offered security, as defined in the Labor Reg. Section
2510.3-101, is a security that is widely held, freely transferable and
registered under the Securities Exchange Act of 1934, as amended.
 
     In addition to the imposition of general fiduciary standards of investment
prudence and diversification, ERISA and the Code prohibit a broad range of
transactions involving Plan assets and persons ('Parties in Interest') having
certain specified relationships to a Plan and impose additional prohibitions
where Parties in Interest are fiduciaries with respect to such Plan. Because the
Loans may be deemed Plan assets of each Plan that purchases Securities, an
investment in the Securities by a Plan might be a prohibited transaction under
ERISA Sections 406 and 407 and subject to an excise tax under Code Section 4975
unless a statutory, regulatory or administrative exemption applies.
 
     In Prohibited Transaction Exemption 83-1 ('PTE 83-1'), which amended
Prohibited Transaction Exemption 81-7, the DOL exempted from ERISA's prohibited
transaction rules and from the excise tax imposed under 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. PTE
83-1 permits, subject to certain conditions, transactions which might otherwise
be prohibited between Plans and Parties in Interest with respect to those Plans
related to the origination, maintenance and termination of mortgage pools
consisting of mortgage loans secured by first or second mortgages or deeds of
trust on single-family residential property, and the acquisition and holding of
certain mortgage pool pass-through certificates representing an interest in such
mortgage pools by Plans. If the general conditions (discussed below) of PTE 83-1
are satisfied, investments by a Plan in Securities that represent interests in a
Pool consisting of Loans ('Single Family Securities') will be exempt from the
prohibitions of ERISA Sections 406(a) and 407 (relating generally to
transactions with Parties in Interest who are not fiduciaries) if the Plan
purchases the Single Family Securities at no more than fair market value and
will be exempt from the prohibitions of ERISA Sections 406(b)(1) and (2)
(relating generally to transactions with fiduciaries) if, in addition, the
purchase is approved by an independent fiduciary, no sales commission is paid to
the pool sponsor, the Plan does not purchase more than 25% of all Single Family
Securities, and at least 50% of all Single Family Securities are purchased by
persons independent of the pool sponsor or pool trustee. PTE 83-1 does not
provide an exemption for transactions involving Subordinate Securities or
Securities representing interests in a pool containing loans secured by shares
in a cooperative. Accordingly, unless otherwise provided in the related
Prospectus Supplement, no transfer of a Subordinate Security or a Security which
is not a Single Family Security may be made to a Plan.
 
     The discussion in this and the next succeeding paragraph applies only to
Single Family Securities. The Depositor believes that, for purposes of PTE 83-1,
the term 'mortgage pass-through certificate' would include: (i) Securities
issued in a Series consisting of only a single class of Securities; and (ii)
Securities issued in a Series in which there is only one class of such
Securities; provided that the Securities in the case of clause (i), or the
Securities in the case of clause (ii), evidence the beneficial ownership of both
a specified percentage of future interest payments (greater than 0%) and a
specified percentage (greater than 0%) of future principal payments on the
Loans. It is not clear whether a class of Securities that evidences the
beneficial ownership in a Trust Fund divided into Loan groups, beneficial
ownership of a specified percentage of interest payments only or principal
payments only, or a notional amount of either principal or interest payments, or
a class of Securities entitled to receive payments of interest and principal on
the Loans only after payments to other classes or after the occurrence of
certain specified events would be a 'mortgage pass-through certificate' for
purposes of PTE 83-1.
 
     PTE 83-1 sets forth three general conditions which must be satisfied for
any transaction to be eligible for exemption: (i) the maintenance of a system of
insurance or other protection for the pooled mortgage loans and property
securing such loans, and for indemnifying Securityholders against reductions in
pass-through payments due to property damage or defaults in loan payments in an
amount not less than the greater of one percent of the aggregate principal
balance of all covered pooled mortgage loans or the principal balance of the
largest covered pooled mortgage loan; (ii) the existence of a pool trustee who
is not an affiliate of the pool sponsor; and (iii) a limitation on the amount of
the payment retained by the pool sponsor, together with other funds inuring to
its
 
                                       92
 

<PAGE>
<PAGE>

benefit, to not more than adequate consideration for selling the mortgage loans
plus reasonable compensation for services provided by the pool sponsor to the
Pool. The Depositor believes that the first general condition referred to above
will be satisfied with respect to the Securities in a Series issued without a
subordination feature, or the Senior Securities only in a Series issued with a
subordination feature, provided that the subordination and Reserve Account,
subordination by shifting of interests, the pool insurance or other form of
credit enhancement described under 'Credit Enhancement' herein (such
subordination, pool insurance or other form of credit enhancement being the
system of insurance or other protection referred to above) with respect to a
Series of Securities is maintained in an amount not less than the greater of one
percent of the aggregate principal balance of the Loans or the principal balance
of the largest Loan. See 'Description of the Securities' herein. In the absence
of a ruling that the system of insurance or other protection with respect to a
Series of Securities satisfies the first general condition referred to above,
there can be no assurance that these features will be so viewed by the DOL. The
Trustee will not be affiliated with the Depositor.
 
     Each Plan fiduciary who is responsible for making the investment decisions
whether to purchase or commit to purchase and to hold Single Family Securities
must make its own determination as to whether the first and third general
conditions, and the specific conditions described briefly in the preceding
paragraph, of PTE 83-1 have been satisfied, or as to the availability of any
other prohibited transaction exemptions. Each Plan fiduciary should also
determine whether, under the general fiduciary standards of investment prudence
and diversification, an investment in the Securities is appropriate for the
Plan, taking into account the overall investment policy of the Plan and the
composition of the Plan's investment portfolio.
 
     The DOL has granted to certain underwriters individual administrative
exemptions (the 'Underwriter Exemptions') from certain of the prohibited
transaction rules of ERISA and the related excise tax provisions of Section 4975
of the Code with respect to the initial purchase, the holding and the subsequent
resale by Plans of certificates in pass-through trusts that consist of certain
receivables, loans and other obligations that meet the conditions and
requirements of the Underwriter Exemptions.
 
     While each Underwriter Exemption is an individual exemption separately
granted to a specific underwriter, the terms and conditions which generally
apply to the Underwriter Exemptions are substantially identical, and include the
following:
 
          (1) the acquisition of the certificates by a Plan is on terms
     (including the price for the certificates) that are at least as favorable
     to the Plan as they would be in an arm's-length transaction with an
     unrelated party;
 
          (2) the rights and interest evidenced by the certificates acquired by
     the Plan are not subordinated to the rights and interests evidenced by
     other certificates of the trust fund;
 
          (3) the certificates acquired by the Plan have received a rating at
     the time of such acquisition that is one of the three highest generic
     rating categories from Standard & Poor's, a Division of The McGraw-Hill
     Companies ('S&P'), Moody's Investors Service, Inc. ('Moody's'), Duff &
     Phelps Credit Rating Co. ('DCR') or Fitch IBCA, Inc. ('Fitch') (S&P,
     Moody's, DCR and Fitch, together, the 'Exemption Rating Agencies');
 
          (4) the trustee is not an affiliate of any other member of the
     Restricted Group as defined below;
 
          (5) the sum of all payments made to and retained by the underwriters
     in connection with the distribution of the certificates represents not more
     than reasonable compensation for underwriting the certificates; the sum of
     all payments made to and retained by the seller pursuant to the assignment
     of the loans to the trust fund represents not more than the fair market
     value of such loans; the sum of all payments made to and retained by the
     servicer and any other servicer represents not more than reasonable
     compensation for such person's services under the agreement pursuant to
     which the loans are pooled and reimbursements of such person's reasonable
     expenses in connection therewith; and
 
          (6) the Plan investing in the certificates is an 'accredited investor'
     as defined in Rule 501(a)(1) of Regulation D of the Securities and Exchange
     Commission under the Securities Act of 1933 as amended.
 
     The trust fund must also meet the following requirements:
 
           (i)  the corpus of the trust fund must consist solely of assets of
                the type that have been included in other investment pools;
 
                                       93
 

<PAGE>
<PAGE>

          (ii)  certificates in such other investment pools must have been rated
                in one of the three highest rating categories by one of the
                Exemption Rating Agencies for at least one year prior to the
                Plan's acquisition of certificates; and
         (iii)  certificates evidencing interests in such other investment pools
                must have been purchased by investors other than Plans for at
                least one year prior to any Plan's acquisition of certificates.
 
     On July 21, 1997, the DOL published in the Federal Register an amendment to
the Underwriter Exemption, which extends exemptive relief to certain
mortgage-backed and asset-backed securities transactions using pre-funding
accounts for trusts issuing pass-through certificates. The amendment generally
allows mortgage loans or other secured receivables (the 'Obligations')
supporting payments to certificateholders, and having a value equal to no more
than twenty-five percent (25%) of the total principal amount of the certificates
being offered by the trust, to be transferred to the trust within a 90-day or
three-month period following the closing date (the 'Pre-Funding Period'),
instead of requiring that all such Obligations be either identified or
transferred on or before the Closing Date. The relief is available when the
following conditions are met:
 
          (1) The ratio of the amount allocated to the pre-funding account to
     the total principal amount of the certificates being offered (the
     'Pre-Funding Limit') must not exceed twenty-five percent (25%).
 
          (2) All Obligations transferred after the Closing Date (the
     'Additional Obligations') must meet the same terms and conditions for
     eligibility as the original Obligations used to create the trust, which
     terms and conditions have been approved by an Exemption Rating Agency.
 
          (3) The transfer of such Additional Obligations to the trust during
     the Pre-Funding Period must not result in the certificates to be covered by
     the Exemption receiving a lower credit rating from an Exemption Rating
     Agency upon termination of the Pre-Funding Period than the rating that was
     obtained at the time of the initial issuance of the certificates by the
     trust.
 
          (4) Solely as a result of the use of pre-funding, the weighted average
     annual percentage interest rate for all of the Obligations in the trust at
     the end of the Pre-Funding Period must not be more than 100 basis points
     lower than the average interest rate for the Obligations transferred to the
     trust on the Closing Date.
 
          (5) In order to insure that the characteristics of the Additional
     Obligations are substantially similar to the original Obligations which
     were transferred to the Trust Fund:
 
             (i) the characteristics of the Additional Obligations must be
        monitored by an insurer or other credit support provider that is
        independent of the depositor; or
 
             (ii) an independent accountant retained by the depositor must
        provide the depositor with a letter (with copies provided to each
        Exemption Rating Agency rating the certificates, the related underwriter
        and the related trustee) stating whether or not the characteristics of
        the Additional Obligations conform to the characteristics described in
        the related prospectus or prospectus supplement and/or pooling and
        servicing agreement. In preparing such letter, the independent
        accountant must use the same type of procedures as were applicable to
        the Obligations transferred to the trust as of the Closing Date.
 
          (6) The Pre-Funding Period must end no later than three months or 90
     days after the Closing Date or earlier in certain circumstances if the
     pre-funding account falls below the minimum level specified in the pooling
     and servicing agreement or an Event of Default occurs.
 
          (7) Amounts transferred to any pre-funding account and/or capitalized
     interest account used in connection with the pre-funding may be invested
     only in certain permitted investments ('Permitted Investments').
 
          (8) The related prospectus or prospectus supplement must describe:
 
             (i) any pre-funding account and/or capitalized interest account
        used in connection with a pre-funding account;
 
             (ii) the duration of the Pre-Funding Period;
 
             (iii) the percentage and/or dollar amount of the Pre-Funding Limit
        for the trust; and
 
             (iv) that the amounts remaining in the pre-funding account at the
        end of the Pre-Funding Period will be remitted to certificateholders as
        repayments of principal.
 
                                       94
 

<PAGE>
<PAGE>

          (9) The related pooling and servicing agreement must describe the
     Permitted Investments for the pre-funding account and/or capitalized
     interest account and, if not disclosed in the related prospectus or
     prospectus supplement, the terms and conditions for eligibility of
     Additional Obligations.
 
     Moreover, the Underwriter Exemptions generally provide relief from certain
self-dealing/conflict of interest prohibited transactions that may occur when
the Plan fiduciary causes a Plan to acquire certificates in a trust as to which
the fiduciary (or its affiliate) is an obligor on the receivables held in the
trust provided that, among other requirements: (i) in the case of an acquisition
in connection with the initial issuance of certificates, at least fifty percent
(50%) of each class of certificates in which Plans have invested is acquired by
persons independent of the Restricted Group, (ii) such fiduciary (or its
affiliate) is an obligor with respect to five percent (5%) or less of the fair
market value of the obligations contained in the trust; (iii) the Plan's
investment in certificates of any class does not exceed twenty-five percent
(25%) of all of the certificates of that class outstanding at the time of the
acquisition; and (iv) immediately after the acquisition, no more than
twenty-five percent (25%) of the assets of any Plan with respect to which such
person is a fiduciary is invested in certificates representing an interest in
one or more trusts containing assets sold or serviced by the same entity. The
Underwriter Exemptions do not apply to Plans sponsored by the Seller, the
related Underwriter, the Trustee, the Master Servicer, any insurer with respect
to the Loans, any obligor with respect to Loans included in the Trust Fund
constituting more than five percent (5%) of the aggregate unamortized principal
balance of the assets in the Trust Fund, or any affiliate of such parties (the
'Restricted Group').
 
     The Prospectus Supplement for each Series of Securities will indicate the
classes of Securities, if any, offered thereby as to which it is expected that
an Underwriter Exemption will apply.
 
     The Underwriter Exemption contains several requirements, some of which
differ from those in PTE 83-l. The Underwriter Exemption contains an expanded
definition of 'certificate' which includes an interest which entitles the holder
to pass-through payments of principal, interest and/or other payments. The
Underwriter Exemption contains an expanded definition of 'trust' which permits
the trust corpus to consist of secured consumer receivables, and to include a
pre-funding account that meets certain requirements. The definition of 'trust',
however, does not include any investment pool unless, inter alia, (i) the
investment pool consists only of assets of the type which have been included in
other investment pools, (ii) certificates evidencing interests in such other
investment pools have been purchased by investors other than Plans for at least
one year prior to the Plan's acquisition of certificates pursuant to the
Underwriter Exemption, and (iii) certificates in such other investment pools
have been rated in one of the three highest generic rating categories of the
four credit rating agencies noted below. Generally, the Underwriter Exemption
holds that the acquisition of the certificates by a Plan must be on terms
(including the price for the certificates) that are at least as favorable to the
Plan as they would be in an arm's length transaction with an unrelated party.
The Underwriter Exemption requires that the rights and interests evidenced by
the certificates not be 'subordinated' to the rights and interests evidenced by
other certificates of the same trust. The Underwriter Exemption requires that
certificates acquired by a Plan have received a rating at the time of their
acquisition that is in one of the three highest generic rating categories of an
Exemption Rating Agency. The Underwriter Exemption specifies that the pool
trustee must not be an affiliate of the pool sponsor, nor an affiliate of the
Underwriter, the pool servicer, any obligor with respect to mortgage loans
included in the trust constituting more than five percent of the aggregate
unamortized principal balance of the assets in the trust, or any affiliate of
such entities. Finally, the Underwriter Exemption stipulates that any Plan
investing in the certificates must be an 'accredited investor' as defined in
Rule 501(a)(1) of Regulation D of the Securities and Exchange Commission under
the Securities Act of 1933.
 
     Any Plan fiduciary which proposes to cause a Plan to purchase Securities
should consult with its counsel concerning the impact of ERISA and the Code, the
applicability of PTE 83-1 and the Underwriter Exemption, and the potential
consequences in their specific circumstances, prior to making such investment.
Moreover, each Plan fiduciary should determine whether under the general
fiduciary standards of investment procedure and diversification an investment in
the Securities is appropriate for the Plan, taking into account the overall
investment policy of the Plan and the composition of the Plan's investment
portfolio.
 
                                LEGAL INVESTMENT
 
     The Prospectus Supplement for each series of Securities will specify which,
if any, of the classes of Securities offered thereby constitute 'mortgage
related securities' for purposes of the Secondary Mortgage Market Enhancement
Act of 1984 ('SMMEA'). Classes of Securities that qualify as 'mortgage related
 
                                       95
 

<PAGE>
<PAGE>

securities' will be legal investments for persons, trusts, corporations,
partnerships, associations, business trusts, and business entities (including
depository institutions, life insurance companies and pension funds) created
pursuant to or existing under the laws of the United States or of any state
(including the District of Columbia and Puerto Rico) whose authorized
investments are subject to state regulations to the same extent as, under
applicable law, obligations issued by or guaranteed as to principal and interest
by the United States or any such entities. Under SMMEA, if a state enacts
legislation prior to October 4, 1991 specifically limiting the legal investment
authority of any such entities with respect to 'mortgage related securities',
securities will constitute legal investments for entities subject to such
legislation only to the extent provided therein. Approximately twenty-one states
adopted such legislation prior to the October 4, 1991 deadline. SMMEA provides,
however, that in no event will the enactment of any such legislation affect the
validity of any contractual commitment to purchase, hold or invest in
securities, or require the sale or other disposition of securities, so long as
such contractual commitment was made or such securities were acquired prior to
the enactment of such legislation.
 
     SMMEA also amended the legal investment authority of federally-chartered
depository institutions as follows: federal savings and loan associations and
federal savings banks may invest in, sell or otherwise deal in Securities
without limitations as to the percentage of their assets represented thereby,
federal credit unions may invest in mortgage related securities, and national
banks may purchase securities for their own account without regard to the
limitations generally applicable to investment securities set forth in 12 U.S.C.
24 (Seventh), subject in each case to such regulations as the applicable federal
authority may prescribe. In this connection, federal credit unions should review
the National Credit Union Administration ('NCUA') Letter to Credit Unions No.
96, as modified by Letter to Credit Unions No. 108, which includes guidelines to
assist federal credit unions in making investment decisions for mortgage related
securities and the NCUA's regulation 'Investment and Deposit Activities' (12
C.F.R. Part 703), which sets forth certain restrictions on investment by federal
credit unions in mortgage related securities (in each case whether or not the
class of Securities under consideration for purchase constituted a 'mortgage
related security'). The NCUA issued final regulations effective December 2, 1991
that restrict and in some instances prohibit the investment by Federal Credit
Unions in certain types of mortgage related securities.
 
     All depository institutions considering an investment in the Securities
(whether or not the class of Securities under consideration for purchase
constitutes a 'mortgage related security') should review the Federal Financial
Institutions Examination Council's Supervisory Policy Statement on the
Securities Activities (to the extent adopted by their respective regulators)
(the 'Policy Statement') setting forth, in relevant part, certain securities
trading and sales practices deemed unsuitable for an institution's investment
portfolio, and guidelines for (and restrictions on) investing in mortgage
derivative products, including 'mortgage related securities', which are
'high-risk mortgage securities' as defined in the Policy Statement. According to
the Policy Statement, such 'high-risk mortgage securities' include securities
such as Securities not entitled to distributions allocated to principal or
interest, or Subordinated Securities. Under the Policy Statement, it is the
responsibility of each depository institution to determine, prior to purchase
(and at stated intervals thereafter), whether a particular mortgage derivative
product is a 'high-risk mortgage security', and whether the purchase (or
retention) of such a product would be consistent with the Policy Statement.
 
     The foregoing does not take into consideration the applicability of
statutes, rules, regulations, orders guidelines or agreements generally
governing investments made by a particular investor, including, but not limited
to 'prudent investor' provisions, percentage-of-assets limits and provisions
which may restrict or prohibit investment in securities which are not 'interest
bearing' or 'income paying,' or in securities which are issued in book-entry
form.
 
     There may be other restrictions on the ability of certain investors,
including depository institutions, either to purchase Securities or to purchase
Securities representing more than a specified percentage of the investor's
assets. Investors should consult their own legal advisors in determining whether
and to what extent the Securities constitute legal investments for such
investors.
 
                             METHOD OF DISTRIBUTION
 
     Securities are being offered hereby in Series from time to time (each
Series evidencing or relating to a separate Trust Fund) through any of the
following methods:
 
          1. By negotiated firm commitment underwriting and public reoffering by
     underwriters;
 
                                       96
 

<PAGE>
<PAGE>

          2. By agency placements through one or more placement agents primarily
     with institutional investors and dealers; and
 
          3. By placement directly by the Depositor with institutional
     investors.
 
     A Prospectus Supplement will be prepared for each Series which will
describe the method of offering being used for that Series and will set forth
the identity of any underwriters thereof and either the price at which such
Series is being offered, the nature and amount of any underwriting discounts or
additional compensation to such underwriters and the proceeds of the offering to
the Depositor, or the method by which the price at which the underwriters will
sell the Securities will be determined. Each Prospectus Supplement for an
underwritten offering will also contain information regarding the nature of the
underwriters' obligations, any material relationship between the Depositor and
any underwriter and, where appropriate, information regarding any discounts or
concessions to be allowed or reallowed to dealers or others and any arrangements
to stabilize the market for the Securities so offered. In firm commitment
underwritten offerings, the underwriters will be obligated to purchase all of
the Securities of such Series if any such Securities are purchased. Securities
may be acquired by the underwriters for their own accounts and may be resold
from time to time in one or more transactions, including negotiated
transactions, at a fixed public offering price or at varying prices determined
at the time of sale.
 
     Underwriters and agents may be entitled under agreements entered into with
the Depositor to indemnification by the Depositor against certain civil
liabilities, including liabilities under the Securities Act of 1933, as amended,
or to contribution with respect to payments which such underwriters or agents
may be required to make in respect thereof.
 
     If a Series is offered other than through underwriters, the Prospectus
Supplement relating thereto will contain information regarding the nature of
such offering and any agreements to be entered into between the Depositor and
purchasers of Securities of such Series.
 
                                 LEGAL MATTERS
 
     The validity of the Securities of each Series, including certain federal
income tax consequences with respect thereto, will be passed upon for the
Depositor by Brown & Wood LLP, One World Trade Center, New York, New York 10048.
 
                             FINANCIAL INFORMATION
 
     A new Trust Fund will be formed with respect to each Series of Securities
and no Trust Fund will engage in any business activities or have any assets or
obligations prior to the issuance of the related Series of Securities.
Accordingly, no financial statements with respect to any Trust Fund will be
included in this Prospectus or in the related Prospectus Supplement.
 
                                     RATING
 
     It is a condition to the issuance of the Securities of each Series offered
hereby and by the Prospectus Supplement that they shall have been rated in one
of the four highest rating categories by the nationally recognized statistical
rating agency or agencies (each, a 'Rating Agency') specified in the related
Prospectus Supplement.
 
     Any such rating would be based on, among other things, the adequacy of the
value of the Trust Fund Assets and any credit enhancement with respect to such
class and will reflect such Rating Agency's assessment solely of the likelihood
that holders of a class of Securities of such class will receive payments to
which such Securityholders are entitled under the related Agreement. Such rating
will not constitute an assessment of the likelihood that principal prepayments
on the related Loans will be made, the degree to which the rate of such
prepayments might differ from that originally anticipated or the likelihood of
early optional termination of the Series of Securities. Such rating should not
be deemed a recommendation to purchase, hold or sell Securities, inasmuch as it
does not address market price or suitability for a particular investor. Each
security rating should be evaluated independently of any other security rating.
Such rating will not address the possibility that prepayment at higher or lower
rates than anticipated by an investor may cause such investor to experience a

lower than anticipated yield or that an investor purchasing a Security at a
significant premium might fail to recoup its initial investment under certain
prepayment scenarios.
 
     There is also no assurance that any such rating will remain in effect for
any given period of time or that it may not be lowered or withdrawn entirely by
the Rating Agency in the future if in its judgment circumstances in the future
so warrant. In addition to being lowered or withdrawn due to any erosion in the
adequacy of the value of the Trust Fund Assets or any credit enhancement with
respect to a Series, such rating might also be lowered or withdrawn among other
reasons, because of an adverse change in the financial or other condition of a
credit enhancement provider or a change in the rating of such credit enhancement
provider's long term debt.
 
     The amount, type and nature of credit enhancement, if any, established with
respect to a Series of Securities will be determined on the basis of criteria
established by each Rating Agency rating classes of such Series. Such criteria
are sometimes based upon an actuarial analysis of the behavior of mortgage loans
in a larger group. Such analysis is often the basis upon which each Rating
Agency determines the amount of credit enhancement required with respect to each
such class. There can be no assurance that the historical data supporting any
such actuarial analysis will accurately reflect future experience nor any
assurance that the data derived from a large pool of mortgage loans accurately
predicts the delinquency, foreclosure or loss experience of any particular pool
of Loans. No assurance can be given that values of any Properties have remained
or will remain at their levels on the respective dates of origination of the
related Loans. If the residential real estate markets should experience an
overall decline in property values such that the outstanding principal balances
of the Loans in a particular Trust Fund and any secondary financing on the
related Properties become equal to or greater than the value of the Properties,
the rates of delinquencies, foreclosures and losses could be higher than those
now generally experienced in the mortgage lending industry. In additional,
adverse economic conditions (which may or may not affect real property values)
may affect the timely payment by mortgagors of scheduled payments of principal
and interest on the Loans and, accordingly, the rates of delinquencies,
foreclosures and losses with respect to any Trust Fund. To the extent that such
losses are not covered by credit enhancement, such losses will be borne, at
least in part, by the holders of one or more classes of the Securities of the
related Series.
