(1) Subject to the permitted variance described herein.
(2) The Class PO Certificates will be  Principal Only Certificates and will  not
    bear interest.
(3) The Class A-8 and Class X Certificates will be Notional Amount Certificates,
    will  have no principal  balance and will bear  interest on their respective
    Notional Amounts  (initially expected  to be  approximately $20,000,000  and
    $186,557,327, respectively).
(4) The Pass-Through Rate for the Class X 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 over (b) 7.625% per annum.
    The  Pass-Through  Rate  for  the   Class  X  Certificates  for  the   first
    Distribution Date is expected to be approximately 1.183% per annum.
     The  Senior Certificates, other than the Class PO and Class X Certificates,
and the Class B-1  and Class B-2  Certificates (collectively, the  'Underwritten
Certificates')  will be  purchased by  Lehman Brothers  Inc. (the 'Underwriter')
from the Depositor and will be offered  by the Underwriter from time to time  in
negotiated  transactions or otherwise at varying  prices to be determined at the
time of sale. The Class A-9 Certificates will also be offered by Edward D. Jones
& Co. (the 'Dealer') from time  to time in negotiated transactions or  otherwise
at  varying  prices  to be  determined  at the  time  of sale.  Proceeds  to the
Depositor from the  sale of  the Underwritten  Certificates are  expected to  be
approximately   96.63%  of  the  aggregate  principal  balance  of  the  Offered
Certificates plus accrued interest,  before deducting issuance expenses  payable
by  the Depositor.  The Class  B-3, Class  PO and  Class X  Certificates will be
transferred to the Seller on or  about August 29, 1996 as partial  consideration
for the sale of the Mortgage Loans to the Depositor.
     The  Underwritten Certificates are  offered by the  Underwriter, subject to
prior sale, when, as  and if delivered  to and accepted  by the Underwriter  and
subject  to its right to reject orders in  whole or in part. It is expected that
delivery  of  the   Underwritten  Certificates,   other  than   the  Class   A-R
Certificates, will be made in book-entry form only through the facilities of The
Depository  Trust Company and that the  Class A-R Certificates will be delivered
at the offices of Lehman Brothers Inc. in New York, New York, in each case on or
about August 29, 1996.

     The  Mortgage Loans will  be sold to the  Depositor by Independent National
Mortgage Corporation ('Indy Mac').
 
     An election will be made to treat the Trust Fund as a 'real estate mortgage
investment conduit' (the 'REMIC') for federal income tax purposes. As  described
more  fully herein and  in the Prospectus, the  Offered Certificates, other than
the Class A-R Certificates,  will constitute 'regular  interests' in the  REMIC.
The Class A-R Certificates will constitute the sole class of 'residual interest'
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 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 WHICH MAY VARY
SIGNIFICANTLY  OVER  TIME.  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  PRINCIPAL  ONLY CERTIFICATES,  THE  RISK THAT  A  SLOWER  THAN
ANTICIPATED  RATE OF PRINCIPAL PAYMENTS COULD RESULT  IN AN ACTUAL YIELD THAT IS
LOWER THAN THE ANTICIPATED  YIELD AND, IN THE  CASE OF ANY OFFERED  CERTIFICATES
PURCHASED  AT A PREMIUM, AND PARTICULARLY  THE NOTIONAL AMOUNT CERTIFICATES, THE
RISK THAT A FASTER THAN ANTICIPATED  RATE OF PRINCIPAL PAYMENTS 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 COULD RESULT IN THE FAILURE OF
SUCH HOLDERS TO RECOVER  THEIR INITIAL INVESTMENTS. 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.
 
     THE  CLASS  A-9 CERTIFICATES  ARE SUBJECT  TO  SPECIAL RULES  REGARDING THE
PROCEDURES,  PRACTICES  AND  LIMITATIONS  APPLICABLE  TO  THE  DISTRIBUTION   OF
PRINCIPAL  OF SUCH CLASS. THE  CLASS A-9 CERTIFICATES MAY  NOT BE AN APPROPRIATE
INVESTMENT FOR ANY INVESTOR WHO REQUIRES  A DISTRIBUTION OF A PARTICULAR  AMOUNT
OF  PRINCIPAL  ON A  PREDETERMINED DATE  OR AN  OTHERWISE PREDICTABLE  STREAM OF
PRINCIPAL DISTRIBUTIONS. THERE IS NO ASSURANCE THAT ANY INVESTOR IN A CLASS  A-9
CERTIFICATE WILL RECEIVE A DISTRIBUTION IN REDUCTION OF ITS PRINCIPAL BALANCE ON
ANY  PARTICULAR  DISTRIBUTION  DATE.   SEE  'DESCRIPTION   OF  THE  CERTIFICATES
- -- DISTRIBUTIONS IN REDUCTION OF THE CLASS A-9 CERTIFICATES.'
 
     The  Class  A-9  Certificates  will  be  entitled  to  the  benefit  of  an
irrevocable financial guaranty insurance policy  (the 'Policy') to be issued  by
Financial  Security  Assurance  Inc.  (the  'Insurer'  or  'Financial Security')
pursuant to which the Insurer will unconditionally and irrevocably guarantee the
payment  of  the  Guaranteed  Distributions  on  the  Class  A-9   Certificates,
respectively on each Distribution Date. See 'Credit Enhancement -- The Financial
Guaranty Insurance Policy.'
 
     The  Underwriter intends  to make  a secondary  market in  the Underwritten
Certificates, but has no  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 November  23,  1994 (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.

                                      permitted variance of plus or minus 5%. Variances in the Class  Certificate
                                      Balances  may result  in variances in  the Notional Amount  of the Notional
                                      Amount Certificates.
                                      The Notional Amount of the Class A-8 Certificates for any Distribution Date

                                      The Notional Amount of the Class  X Certificates for any Distribution  Date

                                      Non-Discount Mortgage Loans  with respect  to such  Distribution Date.  The
                                      initial  Notional Amount of the  Class X Certificates will  be equal to the
                                      aggregate of the  Stated Principal  Balances of  the Non-Discount  Mortgage
                                      Loans as of the Cut-off Date.

                                      Under  certain circumstances described herein, distributions from Available
                                      Funds for  a  Distribution  Date  that  would  otherwise  be  made  on  the
                                      Subordinated   Certificates  may  be  distributed  instead  on  the  Senior
                                      Certificates. See 'Description of the Certificates -- Allocation of Losses'
                                      herein.
Distributions of Interest...........  To the extent funds are available therefor, each interest-bearing Class  of
                                      Certificates  will be  entitled to  receive interest  in the  amount of the
                                      Interest Distribution Amount for such Class. The Class PO Certificates  are
                                      Principal Only Certificates and will not bear interest. See 'Description of
                                      the Certificates -- Interest' herein.
  A. Interest Distribution Amount...  For  each interest-bearing  Class of  Certificates, the  amount of interest
                                      accrued during the related Interest Accrual Period at the applicable  Pass-
                                      Through  Rate on the related Class  Certificate Balance or Notional Amount,
                                      as the case may be.
  B. Pass-Through Rate..............  The  Pass-Through  Rate   for  each  interest-bearing   Class  of   Offered
                                      Certificates  for each Distribution Date will  be as set forth or described
                                      on the cover page hereof.
                                      With respect to each Distribution  Date, the 'Interest Accrual Period'  for
                                      each  interest bearing  Class of  Certificates will  be the  calendar month
                                      preceding the month of such Distribution Date.
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  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.
                                      The  receipt  by  any  Class  A-9  Certificateholder  of  distributions  of
                                      principal is  also dependent  upon a  special procedure  for allocation  of
                                      principal  distributions among the Class  A-9 Certificates described herein
                                      under 'Description of the Certificates -- Distributions in Reduction of the
                                      Class A-9 Certificates.'
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 $2,896,658.
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  will  bear their  proportionate  share of  any  losses
                                      realized  on the  Mortgage Loans in  excess of  the available subordination
                                      amount; provided, that with respect  to the Class A-9 Certificates,  losses
                                      realized  on the  Mortgage Loans in  excess of  the available subordination
                                      amount  will  be   covered  by   the  Policy.  See   'Description  of   the
                                      Certificates    --   Priority   of   Distributions   Among   Certificates,'

Financial Guaranty Insurance Pol-
  icies.............................  In addition to the credit enhancement provided by the subordination of  the
                                      Subordinated Certificates, the Class A-9 Certificates will have the benefit
                                      of  the  Policy pursuant  to which  Financial  Security will  guarantee the
                                      payment of the Guaranteed Distributions on the Class A-9 Certificates.  See
                                      'Credit  Enhancement  --  The  Financial  Guaranty  Insurance  Policy'  and
                                      ' -- Financial Security Assurance Inc.' 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.
                                      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. Further, an investor should consider  the risk that, in the case  of
                                      the   Principal  Only  Certificates  and  any  other  Offered  Certificates
                                      purchased at  a  discount, a  slower  than anticipated  rate  of  principal
                                      payments  (including prepayments) on the 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
                                      Certificate  purchased  at a  premium, a  faster  than anticipated  rate of
                                      principal payments on the 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 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.  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' ('REMIC') for federal income tax purposes. The Regular
                                      Certificates will  constitute  'regular interests'  in  the REMIC  and  the
                                      Residual Certificates will constitute the sole class of 'residual interest'
                                      in  the REMIC. The Class  A-8, Class PO and  Class X 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 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 Senior Certificates (other
                                      than the Class PO, Class X and 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
                                      'mortgage related securities' for purposes of the Secondary Mortgage Market
                                      Enhancement Act of 1984 ('SMMEA') so long  as they are rated in one of  the
                                      two  highest  rating  categories  by  at  least  one  nationally recognized
                                      statistical rating organization  and, as  such, are  legal 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
                                      constitute 'mortgage related securities' for purposes of SMMEA.
                                      Institutions  whose investment activities are  subject to review by federal
                                      or state regulatory authorities  should consult with  their counsel or  the
                                      applicable  authorities to determine  whether an investment  in the Offered

                                      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 Fitch  Investors Service, Inc. ('Fitch')  and that the  Senior
                                      Certificates,  other than the Class A-8, Class PO and Class X Certificates,
                                      be rated AAA by Standard &  Poor's Ratings Group ('S&P' and, together  with
                                      Fitch,  the 'Rating Agencies').  It is a  condition to the  issuance of the
                                      Class A-8, Class PO  and Class X  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 Fitch.  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 Independent National
Mortgage  Corporation  ('Indy  Mac')  pursuant  to  the  Pooling  and  Servicing
Agreement  dated as  of the Cut-off  Date among  Indy Mac, 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  an uncured  material  breach  of  any such
representation, warranty or covenant. 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  that would  adversely
affect   the   interests   of  the   Certificateholders.   See   'Mortgage  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. Indy Mac 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  Indy Mac, 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 $193,103,849 (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 was originated on or after May 1, 1994.
 
     The  latest stated maturity date of any  Mortgage Loan is September 1, 2026
and the earliest stated maturity date of any Mortgage Loan is July 1, 2017.
 
     As of the Cut-off Date,  no Mortgage Loan will  be delinquent more than  30
days.
 
     One  of the Mortgage Loans  is subject to a  buydown agreement. No Mortgage
Loan provides for deferred interest or negative amortization.
 
     No Mortgage Loan had a Loan-to-Value Ratio at origination of more than 95%.
Except for ten Mortgage Loans,  representing approximately 0.91% of the  Cut-off
Date  Pool Principal Balance,  each Mortgage Loan with  a Loan-to-Value Ratio at
origination of greater than 80% will  be covered by a primary mortgage  guaranty
 
                                      S-9

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. Other  than with respect to
rates of  interest, percentages  (approximate) are  stated by  Stated  Principal
Balance  of the Mortgage Loans  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,  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
Trust Fund as a 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
 
     Indy Mac 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  Indy  Mac  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.
 
     Indy   Mac  purchases   mortgage  loans   from  banks,   savings  and  loan
associations, mortgage bankers  (which may or  may not be  affiliated with  Indy
Mac)   and  other   mortgage  loan  originators   (each,  a  'Seller/Servicer').
 
                                      S-12
 

<PAGE>
<PAGE>

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. Indy Mac
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.
 
     Indy Mac currently operates three  mortgage loan purchase programs as  part
of its conduit operations:
 
          1.  Prior Approval  Program. Under this  program, Indy  Mac performs a
     full credit review and  analysis of each mortgage  loan to be purchased  to
     ensure  compliance with  its underwriting  guidelines. Only  after Indy Mac
     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,  Indy Mac 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  Indy  Mac  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 Indy Mac
     approval.  The  Preferred  Delegated Underwriting  Program  is specifically
     designed  for  those  Seller/Servicers  that  meet  higher  financial   and
     performance  criteria than those  applicable to Seller/Servicers generally.
     Under   the   Preferred   Delegated   Underwriting   Program,   each    PDU
     Seller/Servicer is required to underwrite mortgage loans in compliance with
     Indy  Mac'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 Indy  Mac are originated  under the Preferred Delegated
     Underwriting  Program.  Indy  Mac  also  operates  a  restricted  delegated
     underwriting  program that is available to  substantially all of Indy Mac's
     Seller/Servicers. The only mortgage loans that may be submitted under  this
     program are Indy Mac's standard loan products with loan-to-value ratios and
     outstanding  balance requirements that are more restrictive than Indy Mac's
     standard guidelines.
 
     All mortgage loans purchased  by Indy Mac must  meet credit, appraisal  and
underwriting  standards  acceptable to  Indy  Mac. 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.
 
     Indy Mac'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.  Indy  Mac 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. Indy Mac generally
does not  purchase cash-out  refinance mortgage  loans with  original  principal
balances in excess of $1,000,000.
 
     Indy  Mac'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 $200,000.  Indy Mac'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%,  Indy Mac 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  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,  Indy Mac  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, Indy
Mac  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.
 
     Indy Mac  purchases loans  which have  been originated  under one  of  four
documentation   programs:  the  Full   Documentation  Program,  the  Alternative
Documentation Program, the  Reduced Documentation Program  and the No  Income/No
Asset Program.
 
     Under   the   Full  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 Documentation Program.
The  Alternative  Documentation  Program  provides  for  alternative  methods of
employment verification  generally  using W-2  forms  or pay  stubs.  Generally,
mortgage  loans  submitted  under  the  Alternative  Documentation  Program have
maximum Loan-to-Value Ratios which are the same as those described above.
 
     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 20.37%
of the Cut-off Date Pool Principal Balance.
 
     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 Documentation  Program or the  Alternative
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.
 
     No  Seller/Servicers  will  be servicing  more  than 10%  of  the principal
balance of the Mortgage Pool.

                          SERVICING OF MORTGAGE LOANS
 
THE MASTER SERVICER
 
     Indy Mac will act  as Master Servicer. The  principal executive offices  of
Indy Mac are located at 35 North Lake Avenue, Pasadena, California 91101-7139.
 
     The Master Servicer will be responsible for servicing the Mortgage Loans in
accordance  with  the terms  set  forth in  the  Agreement. 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
 
     Indy Mac has  entered into  contracts (each  a 'Seller/Servicer  Contract')
with  Seller/Servicers to sell mortgage loans to Indy Mac and, in most cases, to
perform, as independent contractors, servicing functions for Indy Mac 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. Indy  Mac
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.
Indy Mac 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.  Indy Mac  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, Indy  Mac 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, Indy Mac,  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 Indy  Mac. Indy  Mac has  reserved the  right to  remove the
Seller/Servicer servicing any Mortgage Loan at  any time and will exercise  that
right  if Indy  Mac considers  such removal to  be in  the best  interest of the
Certificateholders. In the event that  Indy Mac removes a Seller/Servicer,  Indy
Mac will continue to be responsible for servicing the related Mortgage Loans.
 
FORECLOSURE AND DELINQUENCY EXPERIENCE
 
     The  following table summarizes the delinquency and foreclosure experience,
respectively, as of December 31,  1994, December 31, 1995  and June 30, 1996  on
approximately  $6.8 billion,  $9.4 billion  and $10.4  billion, respectively, in
outstanding principal balance of conventional mortgage loans master serviced  by
the  Master Servicer. Indy Mac  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
 
                                      S-15

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  many  regions  of  the  country, including
California. 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 the  Mortgage Pool are payable out of the
interest payments  on  each Mortgage  Loan.  The  Expense Fees  will  vary  from
Mortgage  Loan to Mortgage Loan. The rate  at which the Expense Fees accrue (the
'Expense Fee Rate') is  expected to range  from 0.384% to  0.759% per annum,  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   0.386%.  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 0.625% per annum, 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 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.
 
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
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
 
                                      S-16
 

<PAGE>
<PAGE>

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 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.
Any such reduction allocated to the Class A-9 Certificates will be covered first
by the Class A-9 Reserve Fund and thereafter by the Policy. See 'Description  of
the  Certificates -- Interest' and 'Credit Enhancement -- The Financial Guaranty
Insurance Policy' 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. Any failure
by  the Master Servicer to make an  Advance as required under the Agreement with
respect to the Certificates will constitute  an Event of Default thereunder,  in
which  case 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.
 
                        DESCRIPTION OF THE CERTIFICATES
 
GENERAL
 
     The Certificates will be issued pursuant to the Agreement. Set forth  below
are  summaries  of  the specific  terms  and  provisions pursuant  to  which the
Certificates will  be issued.  The  following summaries  do  not purport  to  be
complete  and are subject to,  and are qualified in  their entirety by reference
to, the provisions of the Agreement. When particular provisions or terms used in
the Agreement are referred to,  the actual provisions (including definitions  of
terms) are incorporated by reference.
 
     The  Mortgage Pass-Through Certificates, Series  1996-J will consist of the
Class A-1, Class A-2,  Class A-3, Class  A-4, Class A-5,  Class A-6, Class  A-7,
Class  A-8, Class A-9, Class  A-10, Class A-11, Class PO,  Class X and Class A-R
Certificates (collectively, 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  the 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
 
                                      S-17
 

<PAGE>
<PAGE>

Certificate  Balances  or initial  Notional  Amounts (subject  to  the permitted
variance) and Pass-Through Rates set forth or described on the cover hereof.
 
     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 the Class A-8 Certificates for any Distribution Date
will  be equal to  the Class Certificate  Balance of the  Class A-9 Certificates
with respect  to such  Distribution Date.  The Notional  Amount of  the Class  X
Certificates  for any Distribution  Date will be  equal to the  aggregate of the
Stated Principal Balances  of the  Non-Discount Mortgage Loans  with respect  to
such  Distribution Date. The initial Notional Amount of the Class X Certificates
will be  equal  to  the  aggregate  of the  Stated  Principal  Balances  of  the
Non-Discount Mortgage Loans as of the Cut-off Date.
 
     The Senior Certificates will have an initial aggregate principal balance of
approximately  $176,207,190  and  will  evidence  in  the  aggregate  an initial
beneficial ownership interest  of approximately  91.25% in the  Trust Fund.  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 4.00%, 2.00%, 1.25%, 0.75%, 0.20% and 0.55%, 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.  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 (together with any successor depository selected by the Depositor,
the 'Depository'). Beneficial interests in  the Book-Entry Certificates will  be
held   indirectly  by  investors  through   the  book-entry  facilities  of  the
Depository, as described herein. Investors may hold such beneficial interests in
the Book-Entry Certificates (other than  the Class A-9 Certificates) in  minimum
denominations  representing an original principal amount of $25,000 and integral
multiples of $1,000 in excess  thereof. Investors may hold beneficial  interests
in  the Class A-9 Certificates in minimum denominations representing an original
principal amount of $1,000 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 the Depository  that its nominee will  be CEDE & Co. ('CEDE').
Accordingly, CEDE  is expected  to be  the holder  of record  of the  Book-Entry
Certificates.  Except as described  in the Prospectus  under 'Description of the
Certificates --  Book-Entry  Certificates,'  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 the Depository. 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  the Depository.  Monthly and
annual reports on the Trust Fund provided to CEDE, as nominee of the Depository,
may be made available to beneficial owners upon request, in accordance with  the
rules, regulations and
 
                                      S-18

procedures   creating  and  affecting  the  Depository,  and  to  the  Financial
Intermediaries to whose Depository accounts the Book-Entry Certificates of  such
beneficial owners are credited.
 
     For  a description of the procedures generally applicable to the Book-Entry
Certificates, see 'Description of  the Certificates -- Book-Entry  Certificates'
in the Prospectus.
 
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 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 September  1996 (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,  distributions  will  be  made  on  each
Distribution  Date from Available Funds in  the following order of priority: (i)
to payment  of the  monthly  premium for  the Policy  to  the Insurer;  (ii)  to
interest  on  each  interest-bearing  Class  of  Senior  Certificates;  (iii) to
principal of  the  Classes  of  Senior Certificates  then  entitled  to  receive
distributions of principal, in the order and subject to the priorities set forth
herein under ' -- Principal'; (iv) to any Class PO Deferred Amounts with respect
to  the Class  PO Certificates,  but only from  amounts that  would otherwise be
distributable on  such  Distribution  Date  as  principal  of  the  Subordinated
Certificates;  and  (v) 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.'
 
     'Available Funds' with respect  to any Distribution Date  will be equal  to
the  sum  of (i)  all scheduled  installments  of interest  (net of  the related
Expense Fees) 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 the Mortgage Loans,  to the extent such  proceeds are not applied  to
the  restoration of the related Mortgaged  Property or released to the Mortgagor
in  accordance   with  the   Master  Servicer's   normal  servicing   procedures
(collectively,  'Insurance Proceeds')  and all  other cash  amounts received and
retained in  connection with  the liquidation  of defaulted  Mortgage Loans,  by
foreclosure 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
repurchased by the Seller or the
 
                                      S-19

<PAGE>

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.
 
     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 interest-bearing 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
each interest bearing Class of Certificates will be the calendar month preceding
the month of such Distribution Date.
 
     The interest entitlement  described above  for each  Class of  Certificates
will be reduced by the amount of 'Net Interest Shortfalls' for such Distribution
Date.  With respect  to any Distribution  Date, the 'Net  Interest Shortfall' is
equal to the sum of (i) the  amount of interest which would otherwise have  been
received  with respect to any Mortgage Loan that was the subject of (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  on any
Distribution Date will be allocated pro  rata among all Classes of  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  on such Distribution  Date before taking  into account any
reduction in such amounts resulting from such Net Interest Shortfalls. A 'Relief
Act Reduction' is a  reduction in the  amount of monthly  interest payment on  a
Mortgage  Loan pursuant to the Soldiers' and  Sailors' Civil Relief Act of 1940.
See 'Certain Legal  Aspects of Mortgage  Loans -- Soldiers'  and Sailors'  Civil
Relief  Act' in the Prospectus. With respect  to any Distribution Date, the 'Net
Prepayment  Interest  Shortfall'  is  the  amount  by  which  the  aggregate  of
Prepayment  Interest Shortfalls 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.
 
     In order to provide protection to the holders of the Class A-9 Certificates
against  the allocation thereto of Net Prepayment Interest Shortfalls, a reserve
fund (the  'Class A-9  Reserve Fund')  will  be established  for such  Class  of
Certificates  into  which $24,000  will  be deposited  on  the Closing  Date. No
additional amounts will be deposited into  the Class A-9 Reserve Fund after  the
Closing  Date. If  any Net Prepayment  Interest Shortfalls are  allocated to the
Class A-9 Certificates on any Distribution Date, the amount of such  shortfalls,
to  the  extent of  funds on  deposit in  the  Class A-9  Reserve Fund,  will be
withdrawn therefrom and  will be distributed  on such Distribution  Date to  the
holders of the Class A-9 Certificates. No assurance can be given that the amount
on  deposit  in the  Class  A-9 Reserve  Fund will  be  sufficient to  cover Net
Prepayment Interest Shortfalls allocated to the Class A-9 Certificates under all
circumstances. However, after  the amount on  deposit in the  Class A-9  Reserve
Fund is exhausted, Net Prepayment Interest Shortfalls allocated to the Class A-9
Certificates will be covered by the Policy. The Policy will not cover Relief Act
Reductions allocable to the Class A-9 Certificates on any Distribution Date. See
'Credit Enhancement -- The Financial Guaranty Insurance Policy.'
 
     Accrued  interest  to  be  distributed on  any  Distribution  Date  will be
calculated, in the case of each  interest-bearing 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
applied in the order described above under ' -- Priority of Distributions  Among
Certificates'   are  not  sufficient   to  make  a   full  distribution  of  the
 
                                      S-20
 

<PAGE>
<PAGE>

interest entitlement on the Certificates,  interest will be distributed on  each
Class  of 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 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 will  be allocated  between (i)  the Senior Certificates
(other than the Class PO Certificates and the Notional Amount Certificates)  and
the  Subordinated Certificates and (ii) the  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 7.625%  (each  such  Mortgage  Loan,  a
'Discount   Mortgage  Loan')  will  be  equal  to  ANMR[div]7.625%.  The  Non-PO
Percentage with respect to any  Mortgage Loan with an  ANMR equal to or  greater
than  7.625% (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 (7.625%-ANMR)[div] 7.625%. 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  will  be  distributed  as  principal  of  the Senior
Certificates (other  than  the  Class  PO  Certificates)  and  the  Subordinated
Certificates, to the extent of the amount available from Available Funds for the
distribution of principal on such respective Classes, as described below.
 
     The  Non-PO Formula Principal  Amount for any  Distribution Date will equal
the sum  of the  applicable Non-PO  Percentage of  (a) all  monthly payments  of
principal  due on each Mortgage Loan on  the related Due Date, (b) the principal
portion of the purchase price of each Mortgage Loan that was repurchased by  the
Seller or another person pursuant to the Agreement as of such Distribution Date,
(c)  the Substitution Adjustment Amount in  connection with any Deleted Mortgage
Loan received with respect to such Distribution Date, (d) any Insurance Proceeds
or Liquidation Proceeds allocable to  recoveries of principal of Mortgage  Loans
that  are not yet  Liquidated Mortgage Loans received  during the calendar month
preceding the month of such Distribution Date, (e) with respect to each Mortgage
Loan 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.
 
     Senior  Principal Distribution Amount.  On  each Distribution Date prior to
the Senior Credit Support Depletion Date, the Non-PO Formula Principal Amount up
to the amount of the Senior Principal Distribution Amount for such  Distribution
Date,  will  be distributed  as  principal of  the  following Classes  of Senior
Certificates in the following order of priority:
 
          (i) to the  Class A-11  Certificates, the Priority  Amount, until  the
     Class Certificate Balances thereof have been reduced to zero;
 
          (ii)  if such Distribution Date is on or after September 25, 1999, the
     lesser of  $20,000  and  the Senior  Principal  Distribution  Amount  after
     distributions  pursuant to (i) above, to  the Class A-9 Certificates, until
     the Class Certificate Balance thereof has been reduced to zero;
 
          (iii) concurrently, 68.75% to the Class A-1 Certificates and 31.25% to
     the Class A-10  Certificates, until  the Class Certificate  Balance of  the
     Class A-1 Certificates has been reduced to zero;
 
          (iv) concurrently, 85.9375% to the Class A-2 Certificates and 14.0625%
     to  the Class A-10  Certificates, until an  aggregate amount of $16,256,000
     has been paid pursuant to this step (iv);
 
          (v)  concurrently,  30.8906124632%  to  the  Class  A-2  Certificates,
     64.0545600428% to the Class A-3 Certificates and 5.0548274940% to the Class
     A-10  Certificates, until the Class  Certificate Balances thereof have been
     reduced to zero;
 
          (vi) concurrently, 69.6214836867%  to the Class  A-4 Certificates  and
     30.3785163133%  to the Class A-6  Certificates, until the Class Certificate
     Balance of the Class A-4 Certificates has been reduced to zero;
 
                                      S-21

          (vii) concurrently, 69.6214836867% to  the Class A-5 Certificates  and
     30.3785163133%  to the Class A-6  Certificates, until the Class Certificate
     Balances thereof have been reduced to zero; and
 
          (viii) sequentially, to the Class A-7, Class A-R, Class A-9 and  Class
     A-11  Certificates, in that  order, until the  respective Class Certificate
     Balances thereof have been reduced to zero.
 
     The capitalized terms used herein shall have the following meanings:
 
     Priority Amount for  any Distribution Date  will equal the  sum of (i)  the
product   of  (A)  Scheduled  Principal  Distribution  Amounts,  (B)  the  Shift
Percentage and  (C)  the  Priority  Percentage  and  (ii)  the  product  of  (A)
Unscheduled  Principal Distribution Amounts, (B) the Prepayment Shift Percentage
and (C) the Priority Percentage.
 
     Scheduled Principal  Distribution Amounts  for any  Distribution Date  will
equal  the Non-PO Percentage of all amounts described in clauses (a) through (d)
of the definition  of 'Non-PO  Formula Principal Amount'  for such  Distribution
Date;  provided, however, that  if a Bankruptcy  Loss that is  an Excess Loss is
sustained with respect  to a  Mortgage Loan that  is not  a Liquidated  Mortgage
Loan,  the  Scheduled  Principal Distribution  Amounts  will be  reduced  on the
related Distribution Date by the  applicable Non-PO Percentage of the  principal
portion of such Bankruptcy Loss.
 
     Unscheduled  Principal Distribution Amounts for  any Distribution Date will
equal the sum of (i) with respect to each Mortgage Loan that became a Liquidated
Mortgage Loan during the calendar month preceding the month of such Distribution
Date, the 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 the amount  described in clause (f)  of the definition of  'Non-PO
Formula Principal Amount' for such Distribution Date.
 
     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%.
 
     Priority  Percentage for any Distribution Date  shall equal a fraction, the
numerator of which is equal to the  Class Certificate Balance of the Class  A-11
Certificates  on such Distribution Date and the denominator of which is equal to
the aggregate Class Certificate Balances  of all Classes of Certificates  (other
than the Class PO Certificates) on such Distribution Date.
 
     Prepayment Shift Percentage for any Distribution Date occurring during five
years  beginning on the  first Distribution Date will  equal 0%. Thereafter, the
Prepayment Shift Percentage for any Distribution Date occurring on or after  the
fifth  anniversary of the  first Distribution Date  will be as  follows: for any
Distribution Date in the first year  thereafter, 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,  Available Funds  after payment  of  the
premium  for the Policy and distribution  of interest on the Senior Certificates
will be  distributed,  concurrently,  as  principal of  the  Classes  of  Senior
Certificates   (other  than  the   PO  Certificates  and   the  Notional  Amount
Certificates) 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 will
equal the sum of (i) the  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' for such Distribution Date, (ii) with respect to each
Mortgage Loan that became a Liquidated  Mortgage Loan during the calendar  month
preceding  the month  of such  Distribution Date, the  lesser of  (x) the Senior
Percentage of the applicable Non-PO  Percentage of the Stated Principal  Balance
of such Mortgage Loan and (y) either (A) the Senior Prepayment Percentage or (B)
if  an Excess Loss was  sustained with respect to  such Liquidated Mortgage Loan
during such preceding calendar  month, the Senior  Percentage of the  applicable
Non-PO  Percentage of the  Liquidation Proceeds allocable  to principal received
with respect to such Mortgage Loan,  and (iii) the Senior Prepayment  Percentage
of  the applicable Non-PO Percentage  of the amounts described  in clause (f) of
the definition of Non-PO  Formula Principal Amount  for such Distribution  Date;
provided,   however,   that   if   a  Bankruptcy   Loss   that   is   an  Excess
 
                                      S-22

Loss is sustained  with respect  to a  Mortgage Loan  that is  not a  Liquidated
Mortgage  Loan, the Senior Principal Distribution  Amount will be reduced on the
related Distribution  Date by  the Senior  Percentage of  the applicable  Non-PO
Percentage of the principal portion of such Bankruptcy Loss.
 
     '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  for  any  Distribution  Date  is  the  percentage
equivalent of a fraction the  numerator of which is  the aggregate of the  Class
Certificate  Balances of each Class of Senior Certificates (other than the Class
PO Certificates) immediately prior to such date and the denominator of which  is
the  aggregate of the Class Certificate  Balances of all Classes of Certificates
(other than  the Class  PO Certificates)  immediately prior  to such  date.  The
Subordinated  Percentage for  any Distribution  Date will  be calculated  as the
difference between 100% and the Senior Percentage for such date.
 
     The Senior Prepayment Percentage for any Distribution Date occurring during
the five  years  beginning on  the  first  Distribution Date  will  equal  100%.
Thereafter, the Senior Prepayment Percentage will, except as described below, be
subject  to  gradual reduction  as described  in  the following  paragraph. This
disproportionate allocation  of  certain  unscheduled  payments  in  respect  of
principal  will have the  effect of accelerating the  amortization of the Senior
Certificates while, in the absence  of Realized Losses, increasing the  interest
in  the  Pool  Principal  Balance evidenced  by  the  Subordinated Certificates.
Increasing the respective interest of the Subordinated Certificates relative  to
that  of the Senior Certificates is intended to preserve the availability of the
subordination provided by the Subordinated Certificates.
 
     The Senior Prepayment Percentage for any Distribution Date occurring on  or
after  the fifth anniversary of the first  Distribution Date will be as follows:
for any Distribution Date  in the first year  thereafter, the Senior  Percentage
plus  70% of  the Subordinated  Percentage for  such Distribution  Date; for any
Distribution Date in the second year thereafter, the Senior Percentage plus  60%
of  the Subordinated Percentage for such Distribution Date; for any Distribution
Date in  the  third year  thereafter,  the Senior  Percentage  plus 40%  of  the
Subordinated Percentage for such Distribution Date; for any Distribution Date in
the  fourth year thereafter, the Senior  Percentage plus 20% of the Subordinated
Percentage for such Distribution Date; and for any Distribution Date thereafter,
the Senior Percentage for such Distribution Date (unless on any of the foregoing
Distribution Dates the Senior Percentage exceeds the initial Senior  Percentage,
in  which case the Senior Prepayment  Percentage for such Distribution Date will
once again equal 100%). Notwithstanding the foregoing, no decrease in the Senior
Prepayment Percentage will  occur if  as of the  first Distribution  Date as  to
which  any such decrease  applies, (i) the outstanding  principal balance of all
Mortgage Loans delinquent 60 days or more (averaged over the preceding six month
period), as a percentage of the aggregate principal balance of the  Subordinated
Certificates  (averaged over  the preceding  six month  period), is  equal to or
greater than  50%,  or (ii)  cumulative  Realized  Losses with  respect  to  the
Mortgage  Loans exceed (a)  with respect to  the Distribution Date  on the fifth
anniversary of the first  Distribution Date, 30% of  the aggregate of the  Class
Certificate  Balances of  the Subordinated Certificates  as of  the Closing Date
(the 'Original  Subordinated  Principal  Balance'),  (b)  with  respect  to  the
Distribution  Date on the sixth anniversary  of the first Distribution Date, 35%
of the  Original  Subordinated  Principal  Balance,  (c)  with  respect  to  the
Distribution Date on the seventh anniversary of the first Distribution Date, 40%
of  the  Original  Subordinated  Principal  Balance,  (d)  with  respect  to the
Distribution Date on the eighth anniversary of the first Distribution Date,  45%
of  the Original  Subordinated Principal  Balance, and  (e) with  respect to the
Distribution Date on the ninth anniversary  of the first Distribution Date,  50%
of  the  Original Subordinated  Principal  Balance. The  Subordinated Prepayment
Percentage as of  any Distribution  Date will  be calculated  as the  difference
between 100% and the Senior Prepayment Percentage for such date.
 
     If  on  any  Distribution  Date  the  allocation  to  any  Class  of Senior
Certificates then  entitled  to  distributions of  full  and  partial  principal
prepayments  and other amounts in the percentage required above would reduce the
outstanding Class Certificate Balance of such Class below zero, the distribution
to such Class of Certificates of

the Senior Prepayment Percentage of such amounts for such Distribution Date will
be limited to the percentage necessary  to reduce the related Class  Certificate
Balance to zero.
 
     Subordinated  Principal Distribution Amount.  On each Distribution Date, to
the extent of Available Funds therefor, the Non-PO Formula Principal Amount,  up
to  the  amount  of  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 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
will equal (A)  the sum  of (i) the  Subordinated 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' for such Distribution Date, (ii)
with respect to each Mortgage Loan 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,  after application of  amounts pursuant to
clause (ii) of the  definition of Senior Principal  Distribution Amount and  the
Priority  Amount, up  to the  Subordinated Percentage  of the  applicable Non-PO
Percentage of the Stated Principal Balance  of such Mortgage Loan and (iii)  the
Subordinated  Prepayment Percentage of  the applicable Non-PO  Percentage of the
amounts described in clause (f) of  the definition of 'Non-PO Formula  Principal
Amount'  for such Distribution Date reduced by  (B) the amount of any payment in
respect of Class PO Deferred Amounts on the related Distribution Date.
 
     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
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 the  Class PO  Certificates will  be made  in an
amount (the 'Class PO Principal Distribution Amount') equal to the lesser of (x)
the PO Formula Principal Amount for  such Distribution Date and (y) the  product
of (i) Available Funds remaining after payment of the premium for the Policy and
distribution  of interest  on the Senior  Certificates and (ii)  a fraction, the
numerator of which  is the PO  Formula Principal Amount  and the denominator  of
which  is the sum  of the PO  Formula Principal Amount  and the Senior Principal
Distribution Amount.
 
     If the Class  PO Principal Distribution  Amount on a  Distribution Date  is
calculated  as provided in clause (y)  above, principal distributions to holders
of the Senior Certificates (other than the Class PO Certificates) will be in  an
amount  equal to the product  of (i) Available Funds  remaining after payment of
the  premium  for  the  Policy  and  distribution  of  interest  on  the  Senior
Certificates and (ii) a fraction, the numerator of which is the Senior Principal
Distribution  Amount and the denominator  of which is the  sum of the PO Formula
Principal Amount and the Senior Principal Distribution Amount.
 
     The PO Formula Principal  Amount for any Distribution  Date will equal  the
sum of the applicable PO Percentage of (a) all monthly payments of principal due
on  each Mortgage Loan on the related Due Date, (b) the principal portion of the
purchase price  of each  Mortgage Loan  that was  repurchased by  the Seller  or
another  person pursuant to the Agreement as  of such Distribution Date, (c) the
Substitution Agreement  Amount  in connection  with  any Deleted  Mortgage  Loan
received  with respect to such Distribution  Date, (d) any Insurance Proceeds or
Liquidation Proceeds allocable to recoveries of principal of Mortgage Loans that
are not  yet  Liquidated  Mortgage  Loans received  during  the  calendar  month
preceding the month of such Distribution Date, (e) with respect to each Mortgage
Loan  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 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.
 
DISTRIBUTIONS IN REDUCTION OF THE CLASS A-9 CERTIFICATES
 
     General.    As   to   distributions   of    principal   among   Class   A-9
Certificateholders, Deceased  Holders (as  defined below)  will be  entitled  to
first  priority,  and beneficial  owners  other than  Deceased  Holders ('Living
Holders') will be entitled to a second priority. Beneficial owners of the  Class
A-9  Certificates have the  right to request that  distributions of principal be
made with respect to their Class  A-9 Certificates on each Distribution Date  on
which  distributions  of  principal  are  made with  respect  to  the  Class A-9
Certificates. All such  requested distributions  are subject  to the  priorities
described  below under ' -- Priority of Requested Distributions' and are further
subject to the limitations that they be made (i) only in lots equal to $1,000 of
initial principal balance (each, an 'Individual Class A-9 Certificate') and (ii)
only to the extent that the portion of the Senior Principal Distribution  Amount
allocated  to the  Class A-9  Certificates on  the applicable  Distribution Date
(plus any amounts available from the Rounding Account) provides sufficient funds
for such  requested distributions.  To  the extent  that amounts  available  for
distributions  of principal  on the Class  A-9 Certificates  on any Distribution
Date exceed the aggregate  requests by Deceased Holders  and Living Holders  for
principal  distributions  applicable  to  such  Distribution  Date,  such excess
amounts will be distributed to the  beneficial owners of Class A-9  Certificates
by  random lot, as described under '  -- Mandatory Distributions of Principal on
Class A-9 Certificates.'
 
     On each Distribution Date on which amounts are available for  distributions
of  principal on the  Class A-9 Certificates, the  aggregate amount allocable to
such distributions  will be  rounded, as  necessary, to  an amount  equal to  an
integral  multiple of $1,000,  except as provided below,  in accordance with the
priorities and limitations set forth herein. Such rounding will be  accomplished
on  the first Distribution Date on which distributions of principal on the Class
A-9 Certificates are made by withdrawing, from a non-interest bearing account to
be established on the Closing Date with a $1,000 deposit by the Underwriter (the
'Rounding Account'), the  amount of funds,  if any, needed  to round the  amount
otherwise  available for  such distribution upward  to the  next higher integral
multiple of $1,000. On each succeeding Distribution Date on which  distributions
of  principal on the Class A-9 Certificates are to be made, the aggregate amount
allocable to the Class A-9 Certificates will be applied first to repay any funds
withdrawn from the Rounding Account for the
 
                                      S-25
 

<PAGE>
<PAGE>

Class A-9 Certificates on the prior Distribution Date, and then the remainder of
such allocable amount, if any, will be similarly rounded upward through  another
withdrawal  from the Rounding Account and  distributed as principal on the Class
A-9 Certificates. This  process will continue  on succeeding Distribution  Dates
until  the outstanding principal balance of  the Class A-9 Certificates has been
reduced to  zero. Thus,  the aggregate  distribution made  in reduction  of  the
principal balance of the Class A-9 Certificates on each Distribution Date may be
slightly  more or less  than would be the  case in the  absence of such rounding
procedures,  but  such  difference  will  be  no  more  than  $999.99  on   such
Distribution  Date. Under no circumstances will  the sum of all distributions of
principal on the Class  A-9 Certificates through any  Distribution Date be  less
than  the  sum  that  would  have  resulted  in  the  absence  of  such rounding
procedures.
 
     There is no assurance  that a beneficial owner  of a Class A-9  Certificate
who has submitted a request for a distribution will receive such distribution at
any  particular time after such distribution is requested, since there can be no
assurance that funds  will be  available for  making such  distributions on  any
particular  Distribution Date, or,  even if funds are  available for making such
distributions,  that  such   distributions  with  respect   to  the  Class   A-9
Certificates owned by any particular beneficial owner will be made. Also, due to
the  procedure  for mandatory  distributions described  below,  there can  be no
assurance that  on  any Distribution  Date  on  which the  funds  available  for
distribution  of principal  on the Class  A-9 Certificates  exceed the aggregate
amount of  distributions  requested  by  beneficial  owners  of  the  Class  A-9
Certificates,   any  particular  beneficial  owner   will  receive  a  principal
distribution from  such  excess funds.  Thus,  the timing  of  distributions  of
principal  with  respect  to  any particular  Class  A-9  Certificate  is highly
uncertain, and such  distributions may be  made earlier or  later than the  date
that may be desired by a beneficial owner of a Class A-9 Certificate.
 
     Notwithstanding any provisions herein to the contrary, on each Distribution
Date  on and  after the Senior  Credit Support Depletion  Date, distributions of
principal on the Class A-9 Certificates  (including amounts paid, if any,  under
the  Class A-9 Policy) will be made pro  rata among the holders of the Class A-9
Certificates and will not be made in integral multiples of $1,000 or pursuant to
requested distributions or mandatory distributions by random lot.
 
     Priority of Requested Distributions.  Subject to the limitations  described
herein,  including the order of the receipt  of the request for distributions as
described below under  ' -- Procedure  for Requested Distributions,'  beneficial
owners   of  the  Class  A-9  Certificates   have  the  right  to  request  that
distributions of  principal on  the  Class A-9  Certificates  be made.  On  each
Distribution  Date  on  which  distributions  of  principal  on  the  Class  A-9
Certificates are made, such distributions will be made in the following order of
priority: (i) any  request by  a Deceased  Holder, in an  amount up  to but  not
exceeding  an aggregate principal  amount of $100,000 per  request, and (ii) any
request by a Living Holder,  in an amount up to  but not exceeding an  aggregate
principal  amount of $10,000 per request. Thereafter, distributions will be made
as provided in clause (i)  and (ii) above up to  a second $100,000 and  $10,000,
respectively.  This sequence of priorities will be repeated for each request for
principal  distributions  made  by  the  beneficial  owners  of  the  Class  A-9
Certificates until all such requests have been honored.
 
     Procedure  for Requested Distributions. A beneficial owner may request that
distributions of principal on such beneficial owner's Class A-9 Certificates  be
made  on a  Distribution Date  by delivering a  written request  therefor to the
Participant or  Indirect  Participant  that maintains  such  beneficial  owner's
account  in the Class A-9 Certificates so that the request for such distribution
is received by the Trustee  on or before the  Record Date for such  Distribution
Date.  In the case of a request on behalf of a Deceased Holder, a certified copy
of the death certificate  and any additional appropriate  evidence of death  and
any  tax waivers  are required  to be  forwarded to  the Trustee  under separate
cover. Furthermore, such requests  of Deceased Holders  that are incomplete  may
not  be honored by the Trustee and, if not honored, will lose their priority and
must be rerequested.  The Participant  should in turn  make the  request of  the
Depository  (or, in the case  of an Indirect Participant,  such firm must notify
the related  Participant of  such  request, which  Participant should  make  the
request  of the Depository) on a form required by the Depository and provided to
the Participant. Upon receipt of such request, the Depository will date and time
stamp such request and forward such  request to the Trustee. The Depository  may
establish  such procedures as it deems fair and equitable to establish the order
of receipt of requests for  such distributions received by  it on the same  day.
Neither  the Master Servicer nor the Trustee will be liable for any delay by the
Depository, any  Participant or  any  Indirect Participant  in the  delivery  of
requests  for  distributions  to  the  Trustee.  Requests  for  distributions in
reduction of  principal balance  forwarded to  the Trustee  from the  Depository
after  the Record Date for such Distribution Date and requests for distributions
received in a timely manner but not
 
                                      S-26

accepted with respect to a given Distribution Date, will be treated as  requests
for  distributions on the next succeeding  Distribution Date and each succeeding
Distribution Date thereafter until each request  is accepted or is withdrawn  as
described  below. Each  request for  distributions of  principal on  a Class A-9
Certificate submitted by a beneficial owner  of a Class A-9 Certificate will  be
held  by the Trustee until such request  has been accepted or has been withdrawn
in writing. Each Individual Class A-9  Certificate covered by such request  will
continue  to bear interest  at the related Pass-Through  Rate through the Record
Date for such Distribution Date.
 
     With respect to Class A-9 Certificates  as to which beneficial owners  have
requested distributions on a particular Distribution Date on which distributions
of  principal on  the Class  A-9 Certificates are  being made,  the Trustee will
notify the  Depository and  its  Participants prior  to such  Distribution  Date
whether, and the extent to which, such Class A-9 Certificates have been accepted
for  distributions.  Participants and  Indirect  Participants holding  Class A-9
Certificates are required to  forward such notices to  the beneficial owners  of
such Certificates. Individual Class A-9 Certificates that have been accepted for
a  distribution will be due and payable  on the applicable Distribution Date and
will cease to bear interest after the Record Date for such Distribution Date.
 
     Any beneficial  owner of  a  Class A-9  Certificate  that has  requested  a
distribution   may  withdraw  such  request  by  so  notifying  in  writing  the
Participant or  Indirect  Participant  that maintains  such  beneficial  owner's
account.  The Participant should  forward the withdrawal, on  a form required by
the Depository, to the Trustee. In the event that such account is maintained  by
an  Indirect  Participant, such  Indirect  Participant must  notify  the related
Participant, which in turn must forward  the withdrawal of such request on  such
form  to the Trustee. If such notice of withdrawal of a request for distribution
has not been  received by  the Trustee  on or before  the Record  Date for  such
Distribution  Date,  the  previously  made  request  for  distribution  will  be
irrevocable with respect  to the  making of  distributions of  principal on  the
Class A-9 Certificates on the applicable Distribution Date.
 
     For  purposes of the  foregoing discussion, an  'Indirect Participant' is a
broker,  dealer,  bank,  financial  institution  or  other  person  that  clears
securities  transactions through  or maintains  a custodial  relationship with a
Participant either  directly or  indirectly  and a  'Participant' is  a  broker,
dealer,  bank, financial  institution or  other person  that is  a participating
organization of the Depository.
 
     Mandatory Distributions  of Principal  on Class  A-9 Certificates.  To  the
extent, if any, that distributions of principal on the Class A-9 Certificates on
a  Distribution Date exceed the outstanding  principal balance of the Individual
Class A-9 Certificates  with respect  to which distribution  requests have  been
received by the applicable date, additional Class A-9 Certificates in lots equal
to  Individual  Class A-9  Certificates will  be  selected to  receive principal
distributions in  accordance with  the  then-applicable established  random  lot
procedures  of the Depository, and the then-applicable established procedures of
the Participants and Indirect  Participants, which may or  may not be by  random
lot.  Investors  may  ask  such  Participants  or  Indirect  Participants  which
allocation procedures they use.  Participants and Indirect Participants  holding
Class  A-9 Certificates  selected for  mandatory distributions  of principal are
required to  provide notice  of  such mandatory  distributions to  the  affected
beneficial owners.
 
     Payments to Requesting Beneficial Owners. On any Distribution Date on which
principal  distributions are  made on  the Class  A-9 Certificates,  priority of
payment on the  Class A-9 Certificates  will be given  to beneficial owners  for
whom  Class  A-9  Certificate  principal payment  requests  are  in  effect. The
Depository will honor requests in the following order of priority:
 
          First, the  Depository  will honor  requests  submitted on  behalf  of
     Deceased  Holders in  the order of  their receipt by  the Depository, until
     such requests  have been  honored in  an  amount up  to $100,000  for  such
     requesting Deceased Holder; and
 
          Second,  the  Depository will  honor requests  submitted on  behalf of
     Living Holders  in the  order of  priority established  by the  Depository,
     until  such requests have been honored in  an amount up to $10,000 for each
     requesting Living Holder.
 
     Thereafter, the Depository will honor requests submitted on behalf of  each
Deceased  Holder as provided in step First  up to a second $100,000 and requests
submitted on behalf of  each Living Holder  as provided in step  Second up to  a
second $10,000. This sequence of priorities will be repeated until all Class A-9
Certificate  principal  payment  requests have  been  honored to  the  extent of
amounts available in reduction of the Class A-9 Certificates.

     If the  amount  of  principal  available  for  payment  on  the  Class  A-9
Certificates on a given Distribution Date is insufficient to honor all requests,
such  requests will  be honored  on succeeding  Distribution Dates  as principal
becomes available. In  the case  of requests on  behalf of  Living Holders,  the
Depository  will establish a  new order of priority  for each Distribution Date.
This order will  apply both to  previously unsatisfied payment  requests and  to
newly  submitted  requests. A  Class A-9  Certificate principal  payment request
submitted on behalf of a  Living Holder who later  dies will become entitled  to
the  priority of a newly submitted request  on behalf of a Deceased Holder. Such
priority will  be  effective  for  each  subsequent  Distribution  Date  if  the
Depository  has  received a  certified copy  of the  death certificate  for such
Deceased Holder  and  any  additional  appropriate evidence  of  death  and  any
requested tax waivers by the last Business Day of the preceding calendar month.
 
     Payments  to Non-Requesting Beneficial  Owners. If the  amount of principal
available for payments  on the Class  A-9 Certificates on  a given  Distribution
Date  exceeds the  amount needed  to honor  all Class  A-9 Certificate principal
payment requests, the  Depository will  determine which  Class A-9  Certificates
will  be paid,  using its  established random  lot procedures.  Each Participant
receiving such  payments, and  each Indirect  Participant in  the chain  to  the
beneficial owners, will remit payments to their customers according to their own
procedures,  which may or  may not be  by random lot.  A Participant or Indirect
Participant could decide to  allot Class A-9  Certificate principal payments  to
certain customers (which could include such Participant or Indirect Participant)
without  allotting payments  to others.  Investors should  ask their  brokers or
other intermediaries what allocation procedures they use.
 
     Definition of 'Deceased Holder.' A 'Deceased Holder' is a beneficial  owner
of a Class A-9 Certificate who was living at the time such interest was acquired
and  whose executor or other authorized representative causes to be furnished to
the Trustee a certified copy of  the death certificate for such Deceased  Holder
and  any additional evidence  of death satisfactory  to the Trustee  and any tax
waivers requested by the Trustee.  Class A-9 Certificates beneficially owned  by
tenants  by the entirety, joint tenants or  tenants in common will be considered
to be  beneficially owned  by a  single  owner. The  death of  a tenant  by  the
entirety, joint tenant or tenant in common will be deemed to be the death of the
beneficial  owner, and the Class A-9  Certificates so beneficially owned will be
eligible for priority with respect to distributions of principal, subject to the
limitations stated herein. Class A-9 Certificates beneficially owned by a  trust
will  be considered to be beneficially owned by each beneficiary of the trust to
the extent of such  beneficiary's beneficial interest therein,  but in no  event
will a trust's beneficiaries collectively be deemed to be beneficial owners of a
number  of  Individual  Class  A-9  Certificates  greater  than  the  number  of
Individual Class A-9 Certificates of which such trust is the owner. The death of
a beneficiary of a trust will be deemed to be the death of a beneficial owner of
the Class A-9 Certificates beneficially owned by the trust to the extent of such
beneficiary's beneficial interest in such trust. The death of an individual  who
was a tenant by the entirety, joint tenant or tenant in common in a tenancy that
is  the beneficiary of a trust will be deemed to be the death of the beneficiary
of the  trust. The  death of  a  person who,  during his  or her  lifetime,  was
entitled  to substantially all  of the beneficial ownership  interest in a Class
A-9 Certificate will be deemed to be  the death of the beneficial owner of  such
Class  A-9 Certificates  regardless of  the registration  of ownership,  if such
beneficial ownership  interest can  be established  to the  satisfaction of  the
Trustee;  expenses  incurred  by  the  Trustee in  an  effort  to  determine the
beneficial ownership interest,  including without  limitation, attorney's  fees,
shall  be paid by the beneficial owner.  Such beneficial interest will be deemed
to exist in typical cases  of street name or  nominee ownership, ownership by  a
trustee,  ownership under the Uniform Gifts to Minors Act and community property
or other joint  ownership arrangements  between a husband  and wife.  Beneficial
interest  shall include the  power to sell,  transfer or otherwise  dispose of a
Class A-9 Certificate and the right  to receive the proceeds therefrom, as  well
as  interest and  distributions in reduction  of principal  balance payable with
respect thereto.  As  used  in  this Prospectus  Supplement,  a  request  for  a
distribution  of principal of a Class A-9 Certificate by a Deceased Holder shall
mean a request by the personal representative, surviving tenant by the entirety,
surviving joint tenant or surviving tenant in common of the Deceased Holder.
 
ALLOCATION OF LOSSES
 
     On each Distribution  Date, the  applicable PO Percentage  of any  Realized
Loss,  including any Excess Loss, on a  Discount Mortgage Loan will be allocated
to the 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
 
                                      S-28


<PAGE>
<PAGE>

funds are available on such Distribution Date or on any future Distribution Date
from  amounts that  would otherwise be  allocable 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 in respect of unpaid Class  PO
Deferred  Amounts will not  further reduce the Class  Certificate Balance of the
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 (other than the Notional Amount Certificates and
the  Class  PO  Certificates)  pro  rata,  based  upon  their  respective  Class
Certificate Balances.
 
     On  each  Distribution Date,  the  applicable Non-PO  Percentage  of Excess
Losses will  be allocated  pro rata  among the  Classes of  Senior  Certificates
(other  than the Notional Amount Certificates and the Class PO Certificates) and
the Subordinated  Certificates based  upon  their respective  Class  Certificate
Balances.
 
     Any  Realized Loss, including  any Excess Loss, allocable  to the Class A-9
Certificates will  be covered  by the  Policy. See  'Credit Enhancement  --  The
Financial Guaranty Insurance Policies' herein.
 
     Because  principal  distributions are  paid  to certain  Classes  of Senior
Certificates (other than the Notional Amount Certificates) before other  Classes
of Senior Certificates, holders of such Senior Certificates that are entitled to
receive  principal later bear a greater  risk of being allocated Realized Losses
on the  Mortgage Loans  than holders  of Classes  that are  entitled to  receive
principal earlier.
 
     In  general, a 'Realized Loss' means, with respect to a Liquidated Mortgage
Loan, the amount by which the remaining unpaid principal balance of the Mortgage
Loan exceeds the amount of Liquidation Proceeds applied to the principal balance
of the 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) the Mortgage Pool consists of
two Mortgage Loans with the following characteristics:

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  individual 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 each  Mortgage Loan has
been calculated based on the assumed mortgage loan characteristics described  in
item  (i) above such that the mortgage  loan will amortize in amounts sufficient
to repay the principal  balance of such assumed  mortgage loan by its  remaining
term  to  maturity, (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'  herein, (ix)  interest accrues  on each  interest-bearing
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 August 29, 1996, (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 any Mortgage Loans described herein
under ' -- Optional Purchase of Defaulted Loans' and ' -- Optional  Termination'
and  (xiv) no  Class of  Subordinated Certificates  becomes a  Restricted Class.
While it is assumed  that each of  the Mortgage Loans  prepays at the  specified
constant  Prepayment Assumption,  this is not  likely to be  the case. Moreover,
discrepancies 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%  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  0.666667% (precisely  2/3%) per  annum in  each  month
thereafter  until the nineteenth month. Beginning in the nineteenth 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 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 or
equal to 10% of the  Cut-off Date Pool Principal  Balance. Any such purchase  of
Mortgage  Loans and termination  of the Trust  Fund requires the  consent of the
Insurer if it  would result in  a draw on  the Policy. In  the event the  Master
Servicer  exercises such option and the Insurer  did not withhold its consent to
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 in the case of the Class PO Certificates and, in the case of an
interest-bearing Certificate,  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
 
                                      S-30

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.  Unless  covered  by  the  Policy,  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   'Certain    Federal   Income   Tax
Consequences -- REMIC Certificates --  Tax-Related Restrictions on Transfers  of
Residual  Certificates -- Disqualified Organizations,' ' -- Noneconomic Residual
Interests' and ' --  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 interest bearing 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.  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.
 
     Net  Interest Shortfalls which are not covered by the Policy will adversely
affect the yield on the Class A-9 Certificates, and Net Interest Shortfalls will
adversely affect the  yields on the  other Classes of  Offered Certificates.  In
addition,  although  all  losses initially  will  be borne  by  the Subordinated
Certificates, in the reverse order of their numerical Class designations (either
directly or through distributions in respect of Class PO Deferred Amounts on the
Class  PO  Certificates),  Excess  Losses  will  be  borne  by  all  Classes  of
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 Certificate then entitled to  a
distribution of principal 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.
 
                                      S-31
 

<PAGE>
<PAGE>

     Notwithstanding the foregoing, any Realized Loss allocated to the Class A-9
Certificates   will  be  covered   by  the  Policy.   See  'Description  of  the
Certificates --  Interest' and  'Credit Enhancement  -- The  Financial  Guaranty
Insurance Policies.'
 
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.  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. See 'The Mortgage Pool' herein.
 
     Prepayments,  liquidations and  purchases of the  Mortgage Loans (including
any optional purchase by  the Master Servicer of  a defaulted Mortgage Loan  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 Offered  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.
Further, an investor should consider the risk that, in the case of the Principal
Only  Certificates and any other Offered  Certificate purchased at a discount, a
slower than anticipated  rate of principal  payments (including prepayments)  on
the  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 Certificate purchased at a premium, a faster
than anticipated rate of principal payments  on the 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 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. 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 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  PO Certificates) then  entitled to  receive
principal   distributions.  This  may  result  in  all  (or  a  disproportionate
percentage) of  such  principal  prepayments being  distributed  to  holders  of
certain  Classes of Senior  Certificates (other than  the Class PO Certificates)
and none (or less than their pro rata share) of such principal prepayments being
distributed to holders of  the Subordinated Certificates  during the periods  of
time described in the definitions of 'Senior Prepayment Percentage.'
 
     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.
 
                                      S-32

     As described herein under 'Description of the Certificates -- Distributions
in  Reduction of  the Class  A-9 Certificates,'  the timing  of distributions of
principal with  respect  to  any  particular Class  A-9  Certificate  is  highly
uncertain.  Such  uncertainty  arises  from  the  unpredictability  of principal
payments (including prepayments)  as well  as the special  method of  allocating
among  the  beneficial  owners  of  the Class  A-9  Certificates  the  amount of
principal available for distribution on the Class A-9 Certificates.
 
     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.  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  Classes  of
Certificates, would cause the discounted present value of such assumed stream of
cash  flows to equal the assumed purchase  prices 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
such  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 PRINCIPAL ONLY 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 WILL  HAVE A
NEGATIVE EFFECT ON THE YIELD TO INVESTORS IN THE PRINCIPAL ONLY CERTIFICATES.
 
     As described above  under 'Description of  the Certificates --  Principal,'
the  Class PO  Principal Distribution Amount  is calculated by  reference to the
principal payments (including prepayments) on  the Discount Mortgage Loans.  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 may  prepay at lower
rates, thereby reducing the rate of payment of principal and the resulting yield
of the Class PO Certificates.
 
     The information set forth in the  following table has been prepared on  the
basis  of the Structuring  Assumptions and on the  assumption that the aggregate
purchase price of the Principal Only Certificates (expressed as a percentage  of
initial Class Certificate Balance) is as follows:

     It is highly unlikely that all of the Discount Mortgage Loans will have the
characteristics  assumed or that the Discount  Mortgage Loans will prepay at any
constant rate until maturity or  that all of the  Mortgage Loans will prepay  at
the  same rate or time. As  a result of these factors,  the pre-tax yield on the
Principal Only Certificates is  likely to differ from  those shown in the  table
above,  even  if all  of the  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 life of  the Certificates or as to  the yield on the Principal  Only
Certificates.  Investors must  make their  own decisions  as to  the appropriate
prepayment assumptions to be used in deciding whether to purchase the  Principal
Only Certificates.
 
SENSITIVITY OF THE NOTIONAL AMOUNT CERTIFICATES
 
     AS  INDICATED IN THE  TABLE BELOW, THE  YIELD TO INVESTORS  ON THE NOTIONAL
AMOUNT CERTIFICATES  WILL  BE  SENSITIVE  TO  THE  RATE  OF  PRINCIPAL  PAYMENTS
(INCLUDING  PREPAYMENTS)  OF THE  MORTGAGE LOANS,  PARTICULARLY THOSE  WITH HIGH
ADJUSTED NET MORTGAGE RATES, WHICH GENERALLY CAN BE PREPAID AT ANY TIME. ON  THE
BASIS OF THE ASSUMPTIONS DESCRIBED BELOW, THE YIELD TO MATURITY ON THE CLASS A-8
CERTIFICATES WOULD BE
 
                                      S-33

<PAGE>

APPROXIMATELY   0%  IF  PREPAYMENTS  WERE  TO   OCCUR  AT  A  CONSTANT  RATE  OF
APPROXIMATELY 168% OF THE PREPAYMENT ASSUMPTION AND THE YIELD TO MATURITY ON THE
CLASS X CERTIFICATES WOULD BE APPROXIMATELY 0% IF PREPAYMENTS WERE TO OCCUR AT A
CONSTANT RATE OF APPROXIMATELY 187% OF THE PREPAYMENT ASSUMPTION. IF THE  ACTUAL
PREPAYMENT RATE OF THE MORTGAGE LOANS 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 the  Class X Certificates  in effect from  time to time  is
calculated  by reference to the Adjusted  Net Mortgage Rates of the Non-Discount
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  change in  market interest  rates.  As a  result,  the
Non-Discount  Mortgage Loans  may prepay at  higher rates,  thereby reducing the
Pass-Through Rate and Notional Amount of the Class X Certificate.
 
     The information set forth in the  following table has been prepared on  the
basis  of the Structuring  Assumptions, and on the  assumption that the purchase
price (expressed as  a percentage  of initial Notional  Amount) of  the Class  X
Certificates is as follows:

     It is  highly  unlikely  that all  of  the  Mortgage Loans  will  have  the
characteristics  assumed or that the Mortgage  Loans will prepay at any constant

Certificates. Investors  must make  their own  decisions as  to the  appropriate

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 to be dated August  26,
1996.  Such tables and materials were prepared by the Underwriter 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  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.
 
                                      S-35

DECREMENT TABLES
 
     The  following  tables  indicate  the  percentages  of  the  initial  Class
Certificate Balances  of the  Classes of  Offered Certificates  (other than  the
Class  A-8 and Class X 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  the
Mortgage  Loans 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 Prepayment Assumption 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  is
consistent  with the remaining terms to maturity of the Mortgage Loans specified
in the Structuring Assumptions.
 
     With respect  to the  Class  A-9 Certificates,  the following  tables  also
indicate  the percentages of the initial  Class Certificate Balance of the Class
A-9 Certificates that  would be  outstanding after each  of the  dates shown  at
various constant percentages of SPA and the corresponding weighted average lives
of such Classes.
 
     The  Standard Prepayment Assumption  ('SPA') represents an  assumed rate of
prepayment each month of the then outstanding principal balance of a pool of new
mortgage loans. SPA does not purport  to be either an historical description  of
the  prepayment experience of any pool of  mortgage loans or a prediction of the
anticipated rate of  prepayment of  any pool  of mortgage  loans, including  the
Mortgage  Loans. 100% SPA assumes prepayment rates of 0.2% per annum of the then
unpaid principal balance of such  pool of mortgage loans  in the first month  of
the  life of such mortgage loans and an  additional 0.2% per annum in each month
thereafter (for example,  0.4% per  annum in the  second month)  until the  30th
month.  Beginning in the 30th month and in each month thereafter during the life
of such mortgage loans, 100%  SPA assumes a constant  prepayment rate of 6%  per
annum.  Multiples  may be  calculated from  this  prepayment rate  sequence. For
example, 300% SPA assumes prepayment rates will be 0.60% per annum in month one,
1.20% per annum in month two, and  increasing by 0.60% in each succeeding  month
until  reaching a rate of 18.00% per annum in month 30 and remaining constant at
18.00% per  annum  thereafter.  0%  SPA assumes  no  prepayments.  There  is  no
assurance  that prepayments will occur at any  SPA rate or at any other constant
rate.
 
     The weighted average life of the Class A-9 Certificates shown in the  table
below  applies to such  Class taken as a  whole. Because principal distributions
may be requested  by the  beneficial owners of  the Class  A-9 Certificates  and
because  beneficial  owners of  Class  A-9 Certificates  will  receive principal
distributions by  random  lot,  the  weighted average  life  of  any  Class  A-9
Certificate  beneficially owned by an individual investor may vary significantly
from the weighted average life of the  Class A-9 Certificates taken as a  whole.
There can be no assurance with respect to any particular scenario of the rate of
principal  distributions on the Class  A-9 Certificates, any particular weighted
average life for the Class  A-9 Certificates or the date  or dates on which  any
particular  beneficial  owner will  receive  distributions in  reduction  of the
principal balance of  its Class  A-9 Certificates.  Investors in  the Class  A-9
Certificates  should understand  that they are  assuming all  risks and benefits
associated with the  rate of  principal distributions on  such Certificates  and
variations in such rate from time to time.

*  The  weighted average life of a Certificate of any class is determined by (i)
   multiplying the net reduction, if  any, of the Certificate Principal  Balance
   by  the number of years  from the date of issuance  of the Certificate to the
   related Distribution Date, (ii)  adding the results,  and (iii) dividing  the
   sum  by  the aggregate  of the  net reductions  of the  certificate principal
   balance described in (i) above.

*  The weighted average life of a Certificate of any class is determined by  (i)
   multiplying  the net reduction, if any,  of the Certificate Principal Balance
   by the number of years  from the date of issuance  of the Certificate to  the
   related  Distribution Date, (ii)  adding the results,  and (iii) dividing the
   sum by  the aggregate  of the  net reductions  of the  certificate  principal
   balance described in (i) above.

*  The  weighted average life of a Certificate of any class is determined by (i)
   multiplying the net reduction, if  any, of the Certificate Principal  Balance
   by  the number of years  from the date of issuance  of the Certificate to the
   related Distribution Date, (ii)  adding the results,  and (iii) dividing  the
   sum  by  the aggregate  of the  net reductions  of the  certificate principal
   balance described in (i) above.

LAST SCHEDULED DISTRIBUTION DATE
 
     The Last Scheduled Distribution Date for each Class of Offered Certificates
is the Distribution Date in September 2026 which is the Distribution Date in 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,  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,
Net  Interest  Shortfalls  and  other cash  shortfalls  in  Available  Funds and
distributions 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.
 
     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 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
 
                                      S-42

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.
 
     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 $1,931,038  (the  'Special
Hazard  Loss  Coverage Amount'),  (ii) Bankruptcy  Losses  in an  initial amount
expected to  be up  to  approximately $125,000  (the 'Bankruptcy  Loss  Coverage
Amount')  and  (iii) Fraud  Losses in  an initial  amount expected  to be  up to
approximately $5,793,115 (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 anniversary of the Cut-off Date, to an amount equal
to  the lesser of (i) 2% of the then current Pool Principal Balance and (ii) the
excess of  the Fraud  Loss  Coverage Amount  as of  the  Cut-off Date  over  the
cumulative  amount  of  Fraud Losses  allocated  to the  Certificates  since the
Cut-off Date; (b) on the second,  third and fourth anniversaries of the  Cut-off
Date,  to an  amount equal  to the  lesser of  (i) 1%  of the  then current Pool
Principal Balance and (ii) the  excess of the Fraud  Loss Coverage Amount as  of
the  preceding anniversary  of the  Cut-off Date  over the  cumulative amount of
Fraud Losses allocated to the Certificates since such preceding anniversary, and
(c) 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,  without regard to  the guarantees  provided by the
Policy. 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 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
 
                                      S-43

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 FINANCIAL GUARANTY INSURANCE POLICY
 
THE POLICY
 
     The following summary of the provisions of the financial guaranty insurance
policy  to be issued by Financial Security (the 'Policy') does not purport to be
complete and is qualified in its entirety by reference to the Policy, copies  of
which  may be  obtained from the  Trustee upon request.  Simultaneously with the
issuance of the Certificates, Financial Security will deliver the Policy to  the
Trustee  for the benefit of each holder of the Class A-9 Certificates. Under the
Policy, Financial  Security unconditionally  and irrevocably  guarantees to  the
Trustee  for the benefit of  each holder of the  Class A-9 Certificates the full
and complete payment on each Distribution Date of: (i) the Interest Distribution
Amount for the Class A-9 Certificates for such Distribution Date reduced by  the
amount  of Net  Interest Shortfalls allocated  to such  Certificate arising from
Relief Act  Reductions and  Net Prepayment  Interest Shortfalls,  and; (ii)  Net
Prepayment  Interest Shortfalls allocated to the  Class A-9 Certificates on such
Distribution Date that are not covered by the Class A-9 Reserve Fund; and  (iii)
the  amount of any  Realized Loss, including  any Excess Loss,  allocated to the
Class A-9 Certificates on such  Distribution Date (collectively the  'Guaranteed
Distributions').  In addition, Guaranteed Distributions  shall include the Class
Certificate Balance of the  Class A-9 Certificates to  the extent unpaid on  the
Last  Scheduled  Distribution  Date or  earlier  termination of  the  Trust Fund
pursuant to the terms of the Agreement.  In addition, the Policy will cover  the
amount  of any  payment of principal  or interest to  any holder of  a Class A-9
Certificate which  payment subsequently  is avoided  in whole  or in  part as  a
preference  payment under  applicable law.  THE POLICY  WILL NOT  PROVIDE CREDIT
ENHANCEMENT FOR ANY CLASS OF CERTIFICATES OTHER THAN THE CLASS A-9 CERTIFICATES.
 
     If, by  the  close  of business  on  the  second Business  Day  before  any
Distribution  Date,  the Trustee  determines that  funds expected  to be  in the
Distribution Account on such Distribution Date will be insufficient to make  the
Guaranteed  Distributions on  the Class  A-9 Certificates  for that Distribution
Date, the Trustee is required to make a claim under the Policy in the amount  of
such  deficiency. Payment of claims  under the Policy will  be made by Financial
Security following  Receipt (as  defined  below) by  Financial Security  of  the
appropriate  notice for payment  on the latter  to occur of  (a) 12:00 noon, New
York City time, on the second Business Day following Receipt of such notice  for
payment  and (b)  12:00 noon,  New York  City time,  on the  date on  which such
Guaranteed Distribution is due on the Class A-9 Certificates.
 
     If  payment  of  any  amount  avoided  as  a  preference  under  applicable
bankruptcy, insolvency, receivership or similar law is required to be made under
the Policy, Financial Security shall cause such payment to be made on the latter
of  (a) the date when due to be paid  pursuant to the Order referred to below or
(b) the first  to occur  of (i)  the fourth  Business Day  following Receipt  by
Financial  Security from the Trustee  of (A) a certified  copy of the order (the
'Order') of the court or other governmental body which exercised jurisdiction to
the effect  that  the  Class  A-9  Certificateholders  are  required  to  return
principal  or interest paid with respect to such Certificates during the Term of
the Policy, because such  payments were avoidable  as preference payments  under
applicable bankruptcy law, (B) a certificate of each Class A-9 Certificateholder
that  the Order  has been  entered and  is not  subject to  any stay  and (C) an
assignment duly executed and delivered  by each Class A-9 Certificateholder,  in
such  form as is reasonably  required by Financial Security  and provided to the
Class A-9  Certificateholder by  Financial  Security, irrevocably  assigning  to
Financial  Security all  rights and  claims of  the Class  A-9 Certificateholder
relating to or arising under the Class  A-9 Certificates held by such Class  A-9
Certificateholder  against  the  debtor  that made  such  preference  payment or
otherwise with respect to such preference payment or (ii) the date of Receipt by
Financial Security from the Trustee of the items referred to in clauses (A), (B)
and (C) of  (i) above  if, at least  four Business  Days prior to  such date  of
Receipt,  Financial Security shall have Received written notice from the Trustee
that such items were to be delivered on such date and such date was specified in
such notice.  Such payment  shall  be disbursed  to the  reciever,  conservator,
debtor-in-possession  or trustee in bankruptcy named in the Order and not to the
Trustee   or   any   Class   A-9   Certificateholder   directly   (unless   such
Certificateholder  has previously paid such amount to the receiver, conservator,
debtor-in-possession or trustee in bankruptcy named in the Order, in which  case
such  payment  shall  be  disbursed  to the  Trustee  for  distribution  to such
Certificateholder  upon  proof  of  such  payment  reasonably  satisfactory   to
Financial Security).

In  connection with the foregoing, Financial  Security shall have certain rights
of subrogation, as described in the Agreement.
 
     The terms 'Receipt' and 'Received,' with respect to the Policy, mean actual
delivery to Financial Security and to Financial Security's fiscal agent, if any,
prior to 5:00 p.m., New York City time, on a Business Day; delivery to either on
a day that is not a Business Day  or after 5:00 p.m., New York City time,  shall
be  deemed to be Received on the next  succeeding Business Day. If any notice or
certificate given under the Policies by the Trustee is not in proper form or  is
not  properly completed, executed or  delivered, it shall be  deemed not to have
been Received, and  Financial Security  or its  fiscal agent  shall promptly  so
advise the Trustee and the Trustee may submit an amended notice.
 
     Under the Policy, 'Business Day' means any day other than (i) a Saturday or
Sunday  or (ii) a day on which banking institutions in the City of New York, New
York are authorized or obligated by law or executive order to be closed.
 
     'Term of  the  Policy' mean  the  period from  and  including the  date  of
issuance  of  the  Policy to  and  including the  date  on which  (i)  the Class
Certificate Balance  of all  of the  Class A-9  Certificates is  zero, (ii)  any
payment  on the Class  A-9 Certificates could  have been avoided  in whole or in
part  as  a   preference  payment  under   applicable  bankruptcy,   insolvency,
receivership  or similar law has expired, and (iii) if any proceedings requisite
to avoidance as a preference payment have been commenced prior to the occurrence
of (i) and  (ii), a final  and nonappealable  order in resolution  of each  such
proceeding has been entered.
 
     Financial  Security's  obligations  under  the  Policy  in  respect  of the
Guaranteed Distributions shall be discharged to the extent funds are transferred
to the Trustee as provided in the Policy whether or not such funds are  properly
applied by the Trustee.
 
     Pursuant  to the terms of the Agreement, unless Financial Security fails to
make a required payment under the Policy, a proceeding in bankruptcy shall  have
been instituted by Financial Security or a decree or order for relief shall have
been  issued in respect of a proceeding in bankruptcy against Financial Security
and shall  remain unstayed  for a  period of  60 consecutive  days (together,  a

FINANCIAL SECURITY ASSURANCE INC.
 
     The following information set  forth in this section  has been provided  by
the  Insurer.  Accordingly, neither  the Depositor  nor  the Servicer  makes any
representation as to the accuracy and completeness of such information.
 
     General. Financial  Security Assurance  Inc. (the  'Insurer' or  'Financial
Security')  is a monoline insurance company  incorporated in 1984 under the laws
of the State of  New York. The  Insurer is licensed to  engage in the  financial
guaranty  insurance  business in  all 50  states, the  District of  Columbia and
Puerto Rico.
 
     The Insurer and its subsidiaries are engaged exclusively in the business of
writing financial  guaranty  insurance,  principally in  respect  of  securities
offered  in  domestic  and  foreign  markets.  In  general,  financial  guaranty
insurance consists of  the issuance of  a guaranty of  scheduled payments of  an
issuer's   securities  --   thereby  enhancing   the  credit   rating  of  those
securities -- in consideration for the payment of a premium to the insurer.  The
Insurer and its subsidiaries principally insure asset-backed, collateralized and
municipal   securities.  Asset-backed  securities  are  generally  supported  by
residential mortgage loans, consumer or  trade receivables, securities or  other
assets  having  an  ascertainable  cash  flow  or  market  value. Collateralized
securities include  public  utility  first  mortgage  bonds  and  sale/leaseback
obligation  bonds. Municipal  securities consist  largely of  general obligation
bonds, special revenue bonds  and other special obligations  of state and  local
governments.  The  Insurer  insures both  newly  issued securities  sold  in the
primary market  and outstanding  securities sold  in the  secondary market  that
satisfy the Insurer's underwriting criteria.
 
     The  Insurer is a  wholly owned subsidiary  of Financial Security Assurance
Holdings Ltd.  ('Holdings'), a  New York  Stock Exchange  listed company.  Major
shareholders  of Holdings include Fund American  Enterprises Holdings, Inc., U S
WEST Capital Corporation and  the Tokio Marine and  Fire Insurance Co., Ltd.  No

shareholder of Holdings is obligated to pay any debt of the Insurer or any claim
under  any insurance  policy issued  by the  Insurer or  to make  any additional
contribution to the capital of the Insurer.
 
     The principal executive  offices of  the Insurer  are located  at 350  Park
Avenue,  New York, New York 10022, and  its telephone number at that location is
(212) 826-0100.
 
     Reinsurance.  Pursuant  to  an   intercompany  agreement,  liabilities   on
financial  guaranty insurance  written or  reinsured from  third parties  by the
Insurer or  any of  its domestic  operating insurance  company subsidiaries  are
reinsured  among  such  companies  on  an  agreed-upon  percentage substantially
proportional to  their  respective capital,  surplus  and reserves,  subject  to
applicable  statutory  risk limitations.  In addition,  the Insurer  reinsures a
portion of its  liabilities under  certain of its  financial guaranty  insurance
policies  with  other reinsurers  under various  quota share  treaties and  on a
transaction-by-transaction basis. Such reinsurance is utilized by the Insurer as
a risk management device and to comply with certain statutory and rating  agency
requirements;  it does  not alter or  limit the Insurer's  obligations under any
financial guaranty insurance policy.
 
     Rating of  Claims-Paying Ability.  The Insurer's  claims-paying ability  is
rated  'Aaa' by  Moody's and  'AAA' by  S&P, Nippon  Investors Service  Inc. and
Standard & Poor's (Australia) Pty. Ltd.  Such ratings reflect only the views  of
the  respective rating  agencies, are not  recommendations to buy,  sell or hold
securities and are subject to revision or withdrawal at any time by such  rating
agencies.
 
     Capitalization.  The following table  sets forth the  capitalization of the
Insurer and its  wholly owned subsidiaries  on the basis  of generally  accepted
accounting principles as of June 30, 1996 (in thousands):

     Insurance  Regulation. The Insurer is licensed and subject to regulation as
a financial guaranty insurance  corporation under the laws  of the State of  New
York,  its  state  of  domicile.  In addition,  the  Insurer  and  its insurance
subsidiaries are subject to  regulation by insurance laws  of the various  other
jurisdictions in which they are licensed to do business. As a financial guaranty
insurance    corporation   licensed   to   do   business   in   the   State   of
 
                                      S-46
 

<PAGE>
<PAGE>

New York, the Insurer  is subject to  Article 69 of the  New York Insurance  Law
which, among other things, limits the business of each such insurer to financial
guaranty insurance and related lines, requires that each such insurer maintain a
minimum  surplus to  policyholders, establishes  contingency, loss  and unearned
premium reserve  requirements for  each such  insurer, and  limits the  size  of
individual   transactions  ('single  risks')  and  the  volume  of  transactions
('aggregate risks')  that  may  be  underwritten by  each  such  insurer.  Other
provisions  of  the New  York Insurance  Law,  applicable to  non-life insurance
companies,  such  as  the  Insurer,  regulate,  among  other  things,  permitted
investments,  payment  of  dividends,  transactions  with  affiliates,  mergers,
consolidations, acquisitions or  sales of assets  and incurrence of  liabilities
for borrowings.
 
     The  Policy. Financial Security  shall be subrogated to  the rights of each
holder of a Class A-9 Certificate to receive distributions on such  Certificates
to the extent of any payment by Financial Security under the Policy.
 
     To  the  fullest extent  permitted  by applicable  law,  Financial Security
agrees under the Policy not to assert, and waives, for the benefit of each Class
A-9 Certificateholder  all  its  rights  (whether  by  counterclaim,  setoff  or
otherwise)  and defenses (including, without  limitation, the defense of fraud),
whether acquired by  subrogation, assignment  or otherwise, to  the extent  that
such rights and defenses may be available to Financial Security to avoid payment
of  its obligations under the Policy in accordance with the express provision of
the Policy.
 
     Claims under the  Policy will  rank equally  with any  other unsecured  and
unsubordinated  obligations of Financial Security except for certain obligations
in respect  of tax  and other  payments to  which preference  is or  may  become
afforded  by statute.  Claims against  Financial Security  under the  Policy and
claims against Financial Security under each other financial guaranty  insurance
policy issued thereby constitute pari passu claims against the general assets of
Financial Security. The terms of the Policy cannot be modified or altered by any
other agreement or instrument, or by the merger, consolidation or dissolution of
the  Seller. The Policy may not be cancelled or revoked prior to payment in full
of the Class A-9 Certificates, as appropriate. The Policy is not covered by  the
property/casualty  insurance security  fund specified in  Article 76  of the New
York Insurance Law. The Policy is governed by the laws of the State of New York.
 
     Financial Security does not accept  any responsibility for the accuracy  or
completeness  of  this Prospectus  Supplement or  any information  or disclosure
contained herein, or omitted herefrom, other  than with respect to the  accuracy
of  information  regarding  Financial  Security  set  forth  under  the  heading
' -- Financial Security Assurance Inc.'
 
                                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 will  constitute the  regular
interests in the REMIC. The Residual Certificates will constitute the sole class
of 'residual interest' in the 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 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  'Certain  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%
 
                                      S-47
 

<PAGE>
<PAGE>

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 'Certain  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.
 
     The Internal Revenue Service (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 Regular  Certificates. Additionally,  Treasury
regulations  issued on January 27, 1994  which provide rules for calculating OID
(the 'OID Regulations') do not contain provisions specifically interpreting Code
Section 1272(a)(6). The Trustee intends to base its computations on Code Section
1272(a)(6) and  the OID  Regulations as  described in  the Prospectus  and  this
Prospectus  Supplement. 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.
 
     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 'Certain Federal Income Tax Consequences'
in the Prospectus,  the Offered  Certificates will  represent qualifying  assets
under  Sections 593(d),  856(c)(5)(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.
 
     Prospective  purchasers of a Residual Certificate  should be aware that the
IRS  recently  released  proposed  regulations  (the  'Proposed   Mark-to-Market
Regulations')  which provide that a  Residual Certificate acquired after January
3, 1995  cannot be  marked-to-market.  The Proposed  Mark-to-Market  Regulations
change  the temporary  regulations discussed in  the Prospectus  which allowed a
Residual Certificate to be marked-to-market provided that it was not a 'negative
value' residual  interest  and  did not  have  the  same economic  effect  as  a
'negative  value' residual interest. 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 'Certain  Federal Income  Tax
Consequences   --  REMIC  Certificates  --  b.  Residual  Certificates'  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 'Certain Federal  Income Tax Consequences --  Tax-Related
Restrictions  on  Transfer  of  Residual  Certificates  --  Noneconomic Residual
Certificates,'  'Certain  Federal  Income   Tax  Consequences  --  b.   Residual
Certificates  -- Mark  to Market  Rules,' '  -- Excess  Inclusions' and 'Certain
Federal Income  Tax Consequences  -- Tax-Related  Restrictions on  Transfers  of
Residual Certificates -- Foreign Investors' in the Prospectus. Additionally, for
information  regarding Prohibited Transactions and Treatment of Realized Losses,
see 'Certain  Federal Income  Tax Consequences  -- Prohibited  Transactions  and
Other Taxes' and ' -- REMIC Certificates -- a. Regular Certificates -- Treatment
of Realized 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
 
                                      S-48
 

<PAGE>
<PAGE>

'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  an  individual administrative
exemption to  Lehman  Brothers  Inc. (Prohibited  Transaction  Exemption  91-14,
Exemption  Application No. D-7958,  56 Fed. Reg.  7413 (1991) (the 'Exemption'),
from certain of the prohibited transaction rules of ERISA and the related excise
tax provisions of Section 4975 of the Code with respect to the initial purchase,
the holding and the subsequent resale  by Plans of certificates in  pass-through
trusts  that consist  of certain receivables,  loans and  other obligations that
meet the conditions and requirements of the Exemption. The Exemption applies  to
mortgage loans such as the Mortgage Loans in the Trust Fund.
 
     For  a general description of the Exemption and the conditions that must be
satisfied for  the  Exemption  to  apply,  see  'ERISA  Considerations'  in  the
Prospectus.
 
     It is expected that the Exemption will apply to the acquisition and holding
by  Plans of the Senior Certificates (other than the Class PO, Class X and Class
A-R Certificates) and  that all  conditions of  the Exemption  other than  those
within  the control of  the investors will be  met. In addition,  as of the date
hereof, there is no single Mortgagor that is the obligor on 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  the  Underwriter,  such  Classes of
Certificates do not  currently meet  the requirements  of the  Exemption or  any
comparable  individual  administrative  exemption  granted  to  the 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  B-1, Class B-2 and
Class B-3 Certificates below.
 
     BECAUSE THE CHARACTERISTICS  OF THE  CLASS A-R,  CLASS B-1,  CLASS B-2  AND
CLASS B-3 CERTIFICATES MAY NOT MEET THE REQUIREMENTS OF PTCE 83-1, THE EXEMPTION
OR 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 NOR 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  95-60 ('PTCE  95-60'))  AND  THAT  THE
PURCHASE AND HOLDING OF SUCH CERTIFICATES ARE COVERED UNDER 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
 
                                      S-49
 

<PAGE>
<PAGE>

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 PERSON ACTING ON BEHALF OF A PLAN OR USING SUCH  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 PTCE 83-1 as
described in the Prospectus and the Exemption, and the potential consequences in
their specific  circumstances, prior  to  making an  investment in  the  Offered
Certificates.  Moreover, each Plan fiduciary  should determine whether under the
general fiduciary  standards  of  investment prudence  and  diversification,  an
investment  in the Offered Certificates is appropriate for the Plan, taking into
account the overall  investment policy of  the Plan and  the composition of  the
Plan's investment portfolio.
 
                             METHOD OF DISTRIBUTION
 
     Subject to the terms and conditions set forth in the Underwriting Agreement
between  the Depositor and the Underwriter, the  Depositor has agreed to sell to
the Underwriter, and the Underwriter has agreed to purchase from the  Depositor,
the  Underwritten  Certificates. Distribution  of the  Underwritten Certificates
will be made by the Underwriter  and distribution of the Class A-9  Certificates
will  also be made by the  Dealer, 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
Underwriter may be deemed  to have received compensation  from the Depositor  in
the form of underwriting discounts.
 
     The  Underwriter intends  to make  a secondary  market in  the Underwritten
Certificates, but has no obligation to do  so. There can be no assurance that  a
secondary  market  for the  Offered  Certificates will  develop  or, if  it does
develop, that it will continue or that it will provide Certificateholders with a

                                    RATINGS
 
     It is a condition of the issuance  of the Senior Certificates that they  be
rated  AAA by Fitch and that the  Senior Certificates, other than the Class A-8,
Class PO and Class X Certificates, be rated AAA by S&P (Fitch and S&P, together,
the 'Rating Agencies').  It is a  condition to  the issuance of  the Class  A-8,
Class  PO and  Class X  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 Fitch.
 
     The ratings assigned by Fitch 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. Fitch'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 the  mortgage pool  is  adequate to  make the
payments required by such  certificates. Fitch ratings  on such certificates  do
not,  however, constitute a statement regarding  frequency of prepayments of the
mortgage loans.
 
     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
 
                                  CWMBS, INC.
                                   Depositor
                       Mortgage Pass-Through Certificates
                              (Issuable in Series)
                         ------------------------------
 
    This   Prospectus  relates   to  Mortgage   Pass-Through  Certificates  (the
'Certificates'), which may  be sold  from time  to time  in one  or more  Series
(each,  a 'Series') by CWMBS, Inc. (the  'Depositor') on terms determined at the
time of  sale  and described  in  this  Prospectus and  the  related  Prospectus
Supplement. The Certificates of a Series will evidence beneficial ownership of a
trust  fund (a 'Trust Fund'). As specified in the related Prospectus Supplement,
the Trust  Fund for  a  Series of  Certificates  will include  certain  mortgage
related  assets (the  'Mortgage Assets') consisting  of (i)  first lien mortgage
loans (or  participation  interests  therein) secured  by  one-  to  four-family
residential properties ('Mortgage Loans'), (ii) mortgage pass-through securities
(the  'Agency  Securities')  issued  or guaranteed  by  the  Government National
Mortgage  Association  ('GNMA'),  the  Federal  National  Mortgage   Association
('FNMA')  or  the  Federal Home  Loan  Mortgage Corporation  ('FHLMC')  or (iii)
Private Mortgage-Backed Securities (defined herein). The Mortgage Assets will be
acquired by  the Depositor,  either directly  or indirectly,  from one  or  more
institutions  (each, a 'Seller'), which may  be affiliates of the Depositor, and
conveyed by the  Depositor to  the related  Trust Fund.  A Trust  Fund also  may
include  insurance  policies,  cash accounts,  reinvestment  income, guaranties,
letters of  credit  or other  assets  to the  extent  described in  the  related
Prospectus Supplement.
 
    Each  Series of  Certificates will  be issued in  one or  more classes. Each
class of  Certificates of  a  Series will  evidence  beneficial ownership  of  a
specified  percentage (which may  be 0%) or portion  of future interest payments
and a specified  percentage (which  may be 0%)  or portion  of future  principal
payments  on  the  Mortgage  Assets  in the  related  Trust  Fund.  A  Series of
Certificates may include one or more classes that are senior in right of payment
to one or more other classes of Certificates of such Series. One or more classes
of Certificates  of  a  Series  may be  entitled  to  receive  distributions  of
principal,  interest  or any  combination  thereof prior  to  one or  more other
classes of Certificates  of such  Series or  after the  occurrence of  specified
events, in each case as specified in the related Prospectus Supplement.
 
    Distributions  to holders of Certificates (the 'Certificateholders') will be
made monthly, quarterly,  semi-annually or at  such other intervals  and on  the
dates  specified  in the  related  Prospectus Supplement.  Distributions  on the
Certificates of a Series will be made from the assets of the related Trust  Fund
or  Funds or other assets  pledged for the benefit  of the Certificateholders as
specified in the related Prospectus Supplement.
 
    The Certificates of  any Series  will not be  insured or  guaranteed by  any
governmental  agency or  instrumentality or,  unless otherwise  specified in the
related Prospectus Supplement, by any  other person. Unless otherwise  specified
in the related Prospectus Supplement, the only obligations of the Depositor with
respect  to a Series  of Certificates will be  to obtain certain representations
and warranties from each  Seller and to  assign to the  Trustee for the  related
Series   of   Certificates  the   Depositor's  rights   with  respect   to  such
representations and warranties. The principal obligations of the Master Servicer
named in the related Prospectus Supplement with respect to the related Series of
Certificates will be limited to obligations pursuant to certain  representations
and  warranties  and to  its  contractual servicing  obligations,  including any
obligation it may have to advance delinquent payments on the Mortgage Assets  in
the related Trust Fund.
 
    The  yield on each  class of Certificates  of a Series  will be affected by,
among other things, the rate of payment of principal (including prepayments)  on
the  Mortgage Assets in the related Trust Fund and the timing of receipt of such
payments as described herein and in  the related Prospectus Supplement. A  Trust
Fund  may  be subject  to early  termination  under the  circumstances described
herein and in the related Prospectus Supplement.
 
    If specified in a Prospectus Supplement,  one or more elections may be  made
to  treat the related Trust Fund or specified portions thereof as a 'real estate
mortgage investment  conduit' ('REMIC')  for federal  income tax  purposes.  See
'Certain Federal Income Tax Consequences' herein.

THESE  SECURITIES HAVE  NOT BEEN APPROVED  OR DISAPPROVED BY  THE SECURITIES AND
   EXCHANGE COMMISSION  OR  ANY  STATE  SECURITIES  COMMISSION  NOR  HAS  THE
     SECURITIES   AND   EXCHANGE   COMMISSION  OR   ANY   STATE  SECURITIES
       COMMISSION  PASSED  UPON   THE  ACCURACY  OR   ADEQUACY  OF   THIS
         PROSPECTUS   OR   THE  RELATED   PROSPECTUS   SUPPLEMENT.  ANY
             REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.
                         ------------------------------
 
    Prior to issuance there will have been no market for the Certificates of any
Series, and  there  can  be  no  assurance  that  a  secondary  market  for  any
Certificates  will develop or, if  it does develop, that  it will continue. This
Prospectus may  not be  used to  consummate sales  of a  Series of  Certificates
unless accompanied by a Prospectus Supplement.
 
    Offers  of  the  Certificates may  be  made  through one  or  more different
methods, including offerings through underwriters, as more fully described under
'Method of Distribution' herein and 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. The loan agreement or promissory note (the  'Mortgage
                                                Note')  in respect of a Mortgage Loan may provide for the payment
                                                of interest at a rate lower than the interest rate (the 'Mortgage
                                                Rate') specified in such  Mortgage Note 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 a third party.
                                            (b)  Principal may be payable on a  level debt service basis to fully
                                                amortize the loan over its term,  may be calculated on the  basis
                                                of  an assumed amortization schedule that is significantly longer
                                                than the original term to maturity or on an interest rate that is
                                                different from the interest rate on the Mortgage Loan or may  not
                                                be  amortized  during  all or  a  portion of  the  original term.
                                                Payment of all or a substantial  portion of the principal may  be
                                                due  on  maturity  ('balloon  payments').  Principal  may include
                                                interest that  has  been  deferred and  added  to  the  principal
                                                balance of the Mortgage Loan.
                                            (c)  Monthly payments of principal and  interest may be fixed for the
                                                life of the loan, may increase over a specified period of time or
                                                may change  from period  to period.  Mortgage Loans  may  include
                                                limits  on  periodic  increases  or decreases  in  the  amount of
                                                monthly payments and  may include maximum  or minimum amounts  of
                                                monthly payments.
                                            (d) The  Mortgage Loans generally may be  prepaid at any time without
                                                payment of any  prepayment fee.  If so specified  in the  related
                                                Prospectus Supplement, prepayments of principal may be subject to
                                                a  prepayment fee, which  may be fixed  for the life  of any such
                                                Mortgage Loan or may decline over time, and may be prohibited for
                                                the life  of  any  such  Mortgage Loan  or  for  certain  periods
                                                ('lockout   periods').   Certain   Mortgage   Loans   may  permit
                                                prepayments after expiration of the applicable lockout period and
                                                may require the payment  of a prepayment  fee in connection  with
                                                any  such subsequent prepayment. Other  Mortgage Loans may permit
                                                prepayments without payment of a fee unless the prepayment occurs
                                                during specified  time periods.  The Mortgage  Loans may  include
                                                'due-on-sale' clauses which

                                            The rights  of the  holders  of the  Subordinated Certificates  of  a
                                            Series    (the   'Subordinated    Certificateholders')   to   receive

                                            afforded to the Senior Certificateholders of a Series by means of the

                                            of  principal and interest due them  on each Distribution Date out of
                                            the funds  available for  distribution on  such date  in the  related
                                            Certificate  Account  and, to  the  extent described  in  the related

                                            otherwise  have been payable  to the Subordinated Certificateholders;
                                            (ii) reducing  the ownership  interest  of the  related  Subordinated
                                            Certificates;  (iii) a combination of clauses  (i) and (ii) above; or
                                            (iv) as otherwise described in the related Prospectus Supplement.  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

                                            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 Certificates (whether or not such
                                            class  constitutes  a  'mortgage  related  security')  complies  with
                                            applicable guidelines, policy statements or restrictions. See  'Legal

                                            depending on whether  one or  more elections  are made  to treat  the
                                            Trust  Fund or specified portions thereof  as a 'real estate mortgage
                                            investment conduit' ('REMIC')  under the provisions  of the  Internal
                                            Revenue  Code  of  1986,  as  amended  (the  'Code').  The Prospectus
                                            Supplement for each Series of Certificates will specify whether  such
                                            an   election  will  be   made.  See  'Certain   Federal  Income  Tax

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

                                            of  counsel to  the effect  that such transfer  will not  result in a
                                            violation of the prohibited transaction  provisions of ERISA and  the
                                            Code  and will not  subject the Trustee, the  Depositor or the Master

                                THE TRUST FUND*
 
     The  Trust Fund for each Series will be held by the Trustee for the benefit
of the  related Certificateholders.  Each  Trust Fund  will consist  of  certain
mortgage-related  assets (the  'Mortgage Assets')  consisting of  (A) a mortgage
pool (a 'Mortgage Pool') comprised of  Mortgage Loans, (B) Agency Securities  or
(C) Private Mortgage-Backed Securities, in each case as specified in the related
Prospectus Supplement, together with payments in respect of such Mortgage Assets
and certain other accounts, obligations or agreements, in each case as specified
in the related Prospectus Supplement.
 
     The Certificates will be entitled to payment from the assets of the related
Trust  Fund  or other  assets pledged  for the  benefit of  the holders  of such
Certificates (the 'Certificateholders') as  specified in the related  Prospectus
Supplement  and will not be entitled to payments in respect of the assets of any
other trust fund established by the Depositor. Unless otherwise specified in the
related Prospectus  Supplement,  the Mortgage  Assets  of any  Trust  Fund  will
consist   of  Mortgage  Loans,  Agency  Securities  or  Private  Mortgage-Backed
Securities but not a combination thereof.
 
     The Mortgage Assets may  be acquired by the  Depositor, either directly  or
through  affiliates, from originators  or sellers that may  be affiliates of the
Depositor (the 'Sellers')  and conveyed by  the Depositor to  the related  Trust
Fund.  Mortgage Loans  acquired by  the Depositor  will have  been originated in
accordance with the underwriting criteria  specified below under 'Mortgage  Loan
Program  --  Underwriting  Standards' or  as  otherwise described  in  a related
Prospectus Supplement.
 
     The following is a brief description of the Mortgage Assets expected to  be
included  in the  Trust Funds. If  specific information  respecting the Mortgage
Assets is not known at the time the related Series of Certificates initially  is
offered, more general information of the nature described below will be provided
in the related Prospectus Supplement, and 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  Certificates  (the
'Detailed  Description'). A  schedule of  the Mortgage  Assets relating  to such
Series will be attached to the Agreement delivered to the Trustee upon  delivery
of the Certificates.
 
THE MORTGAGE LOANS -- GENERAL
 
     For  purposes  hereof,  the real  property  that secures  repayment  of the
Mortgage Loans  is  referred  to collectively  as  'Mortgaged  Properties'.  The
Mortgaged Properties may be located in any one of the fifty states, the District
of  Columbia, Guam,  Puerto Rico  or any other  territory of  the United States.
Mortgage Loans  with  certain  Loan-to-Value  Ratios  and/or  certain  principal
balances  may  be  covered  wholly or  partially  by  primary  mortgage guaranty
insurance policies (each, a 'Primary Mortgage Insurance Policy'). The existence,
extent and duration  of any such  coverage will be  described in the  applicable
Prospectus Supplement.
 
     Unless otherwise specified in the related Prospectus Supplement, all of the
Mortgage  Loans in a Mortgage  Pool will have monthly  payments due on the first
day of each month. The payment terms of  the Mortgage Loans to be included in  a
Trust  Fund  will be  described  in the  related  Prospectus Supplement  and may
include any of the following features  or combination thereof or other  features
described in the related Prospectus Supplement:
 
          (a)  Interest may be payable  at a fixed rate,  a rate adjustable from
     time to  time in  relation to  an index  (which will  be specified  in  the
     related  Prospectus Supplement), a rate that is  fixed for a period of time
     or under certain  circumstances and is  followed by an  adjustable rate,  a
     rate that otherwise varies from time to time, or a rate that is convertible
     from  an adjustable rate to a fixed rate. Changes to an adjustable rate may
     be subject  to periodic  limitations,  maximum rates,  minimum rates  or  a
     combination 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. A Mortgage Note may
     provide for the payment of interest at a rate lower than the Mortgage  Rate
     specified in such Mortgage Note 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 Mortgaged Property or another source.
 
                         ------------------------------
 
* Whenever the  terms  'Mortgage  Pool'  and 'Certificates'  are  used  in  this
  Prospectus,  such terms will be deemed  to apply, unless the context indicates
  otherwise, to one  specific Mortgage  Pool and  the Certificates  representing
  certain  undivided interests, as described below,  in a single trust fund (the
  'Trust Fund') consisting  primarily of  the Mortgage Assets  in such  Mortgage
  Pool.  Similarly, the term 'Pass-Through Rate'  will refer to the Pass-Through
  Rate borne by  the Certificates  of one specific  Series and  the term  'Trust
  Fund' will refer to one specific Trust Fund.

          (b)  Principal may be payable  on a level debt  service basis to fully
     amortize the Mortgage 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
     Mortgage  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  payments'). Principal  may include  interest
     that  has been deferred and added to  the principal balance of the Mortgage
     Loan.
 
          (c) Monthly payments of  principal and interest may  be fixed for  the
     life  of the Mortgage Loan, may increase over a specified period of time or
     may change from period to period. The terms of a Mortgage Loan may  include
     limits on periodic increases or decreases in the amount of monthly payments
     and may include maximum or minimum amounts of monthly payments.
 
          (d)  The Mortgage Loans  generally may be prepaid  at any time without
     the payment  of  any  prepayment  fee.  If  so  specified  in  the  related
     Prospectus  Supplement, some prepayments  of principal may  be subject to a
     prepayment fee, which may be fixed for  the life of any such Mortgage  Loan
     or  may  decline over  time, and  may be  prohibited for  the life  of such
     Mortgage Loan or for certain periods ('lockout periods'). Certain  Mortgage
     Loans  may permit  prepayments after  expiration of  the applicable lockout
     period and may require the payment  of a prepayment fee in connection  with
     any such subsequent prepayment. Other Mortgage Loans may permit prepayments
     without payment of a fee unless the prepayment occurs during specified time
     periods.  The  loans  may  include 'due-on-sale'  clauses  that  permit the
     mortgagee to demand payment of the entire Mortgage Loan in connection  with
     the  sale or  certain transfers  of the  related Mortgaged  Property. Other
     Mortgage Loans  may be  assumable by  persons meeting  the then  applicable
     underwriting standards of the Seller.
 
     A  Trust Fund  may contain  certain Mortgage  Loans ('Buydown  Loans') that
include provisions  whereby  a  third party  partially  subsidizes  the  monthly
payments of the obligors on such Mortgage Loans (each, a 'Mortgagor') during the
early  years of such Mortgage Loans, the difference to be made up from a fund (a
'Buydown Fund') contributed by  such third party at  the time of origination  of
the  Mortgage Loan.  A Buydown  Fund will be  in an  amount equal  either to the
discounted value  or full  aggregate  amount of  future payment  subsidies.  The
underlying  assumption of buydown plans is that the income of the Mortgagor will
increase  during  the  buydown  period  as  a  result  of  normal  increases  in
compensation  and inflation, so that the Mortgagor will be able to meet the full
mortgage payments at  the end of  the buydown  period. To the  extent that  this
assumption  as to increased income is not fulfilled, the possibility of defaults
on Buydown Loans is  increased. The related  Prospectus Supplement will  contain
information  with  respect to  any Buydown  Loan  concerning limitations  on the
interest rate  paid by  the  Mortgagor initially,  on  annual increases  in  the
interest rate and on the length of the buydown period.
 
     Each Prospectus Supplement will contain information, as of the date of such
Prospectus  Supplement  and  to  the  extent  then  specifically  known  to  the
Depositor, with respect to the Mortgage Loans contained in the related  Mortgage
Pool,  including (i) the aggregate outstanding principal balance and the average
outstanding principal balance of the Mortgage Loans as of the applicable Cut-off
Date, (ii) the  type of  property securing  the Mortgage  Loans (e.g.,  separate
residential  properties, individual units in  condominium apartment buildings or
in buildings owned  by Cooperatives, vacation  and second homes,  or other  real
property),  (iii) the original terms to maturity of the Mortgage Loans, (iv) the
largest principal  balance and  the smallest  principal balance  of any  of  the
Mortgage  Loans, (v) the  earliest origination date and  latest maturity date of
any of the  Mortgage Loans,  (vi) the  aggregate principal  balance of  Mortgage
Loans  having  Loan-to-Value  Ratios  at origination  exceeding  80%,  (vii) the
maximum and  minimum  per  annum  Mortgage Rates  and  (viii)  the  geographical
distribution  of  the Mortgage  Loans.  If specific  information  respecting the
Mortgage  Loans  is  not  known  to  the  Depositor  at  the  time  the  related
Certificates  are  initially offered,  more  general information  of  the nature
described above will be provided in the Detailed Description.
 
     The 'Loan-to-Value  Ratio' of  a Mortgage  Loan at  any given  time is  the
fraction,  expressed as  a percentage,  the numerator  of which  is the original
principal balance of the related Mortgage  Loan and the denominator of which  is
the  Collateral  Value  of  the  related  Mortgaged  Property.  Unless otherwise
specified in  the related  Prospectus Supplement,  the 'Collateral  Value' of  a
Mortgaged  Property is the  lesser of (a)  the appraised value  determined in an
appraisal obtained by the  originator at origination of  such Mortgage Loan  and
(b) the sales price for such property.
 
     No  assurance can  be given  that values  of the  Mortgaged Properties have
remained or will  remain at  their levels  on the  dates of  origination of  the
related  Mortgage Loans. If the residential real estate market should experience
an overall  decline  in property  values  such that  the  outstanding  principal
balances of the Mortgage
 
                                       12

Loans,  and any secondary financing on the Mortgaged Properties, in a particular
Mortgage Pool  become  equal to  or  greater than  the  value of  the  Mortgaged
Properties,  the actual rates of delinquencies, foreclosures and losses could be
higher than those now generally experienced in the mortgage lending industry. In
addition, adverse economic conditions  and other factors (which  may or may  not
affect  real property  values) may  affect the  timely payment  by Mortgagors of
scheduled payments  of  principal  and  interest  on  the  Mortgage  Loans  and,
accordingly,  the actual  rates of  delinquencies, foreclosures  and losses with
respect to any Mortgage 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 Certificates of the related Series.
 
     The  Depositor will cause the Mortgage  Loans comprising each Mortgage Pool
to be assigned to the Trustee named in the related Prospectus Supplement for the
benefit of the  Certificateholders of  the related Series.  The Master  Servicer
named  in the  related Prospectus  Supplement will  service the  Mortgage Loans,
either   directly   or   through    other   mortgage   servicing    institutions
('Sub-Servicers'),  pursuant  to a  Pooling  and Servicing  Agreement  (each, an
'Agreement'), and  will receive  a fee  for such  services. See  'Mortgage  Loan
Program'  and  'The Pooling  and Servicing  Agreement'  herein. With  respect to
Mortgage Loans  serviced by  the  Master Servicer  through a  Sub-Servicer,  the
Master  Servicer  will remain  liable for  its  servicing obligations  under the
related Agreement as if the Master  Servicer alone were servicing such  Mortgage
Loans.
 
     Unless  otherwise specified in the  related Prospectus Supplement, the only
obligations of the Depositor with respect to a Series of Certificates will be to
obtain certain representations and warranties from the Sellers and to assign  to
the  Trustee for such Series of Certificates the Depositor's rights with respect
to  such  representations  and  warranties.  See  'The  Pooling  and   Servicing
Agreement  --  Assignment of  Mortgage Assets'  herein.  The obligations  of the
Master Servicer with respect to the  Mortgage Loans will consist principally  of
its contractual servicing obligations under the related Agreement (including its
obligation  to enforce the obligations of the Sub-Servicers or Sellers, or both,
as more fully described herein  under 'Mortgage Loan Program --  Representations
by Sellers; Repurchases' and its obligation to make certain cash advances (each,
an  'Advance') in the event  of delinquencies in payments  on or with respect to
the Mortgage Loans  in the amounts  described herein under  'Description of  the
Certificates  --  Advances'.  The obligations  of  the Master  Servicer  to make
Advances may be subject to limitations, to the extent provided herein and in the
related Prospectus Supplement.
 
     Unless otherwise specified in  the related Prospectus Supplement,  Mortgage
Loans  will consist of mortgage loans, deeds of trust or participations or other
beneficial interests  therein, secured  by first  liens on  one- to  four-family
residential  properties.  If  so  specified,  the  Mortgage  Loans  may  include
cooperative apartment loans ('Cooperative Loans') secured by security  interests
in  shares  issued  by  private,  non-profit,  cooperative  housing corporations
('Cooperatives') and in the related  proprietary leases or occupancy  agreements
granting   exclusive  rights   to  occupy   specific  dwelling   units  in  such
Cooperatives' buildings. If so specified  in the related Prospectus  Supplement,
the Mortgage Assets of the related Trust Fund may include mortgage participation
certificates   evidencing  interests  in  Mortgage  Loans.  Such  loans  may  be
conventional loans  (i.e., loans  that  are not  insured  or guaranteed  by  any
governmental  agency) or loans insured by the FHA or partially guaranteed by the
VA, as specified in the related Prospectus Supplement.
 
     The Mortgaged  Properties  relating  to  Mortgage  Loans  will  consist  of
detached  or  semi-detached  one-family  dwelling  units,  two-  to  four-family
dwelling units, townhouses, rowhouses, individual condominium units,  individual
units  in  planned  unit developments  and  certain other  dwelling  units. Such
Mortgaged  Properties  may  include   vacation  and  second  homes,   investment
properties and leasehold interests. In the case of leasehold interests, the term
of  the leasehold will exceed the scheduled  maturity of the Mortgage Loan by at
least  five  years,  unless  otherwise  specified  in  the  related   Prospectus
Supplement.
 
AGENCY SECURITIES
 
     Government National Mortgage Association.  GNMA is a wholly-owned corporate
instrumentality  of  the  United States  with  the United  States  Department of
Housing and  Urban Development.  Section  306(g) of  Title  II of  the  National
Housing  Act  of  1934,  as  amended (the  'Housing  Act'),  authorizes  GNMA to
guarantee the timely payment  of the principal of  and interest on  certificates
(the 'GNMA Certificates') that represent an interest in a pool of mortgage loans
insured  by the FHA under the Housing Act or  Title V of the Housing Act of 1949
('FHA Loans'),  or  partially  guaranteed  by  the  VA  under  the  Servicemen's
Readjustment  Act of 1944, as amended, or  Chapter 37 of Title 38, United States
Code ('VA Loans').
 
     Section 306(g) of the Housing Act provides that 'the full faith and  credit
of  the United  States is  pledged to the  payment of  all amounts  which may be
required to be paid under any guaranty under this subsection.' In order to  meet
its  obligations under any such guaranty, GNMA  may, under Section 306(d) of the
Housing Act,
 
                                       13

borrow from the United States  Treasury in an unlimited  amount which is at  any
time sufficient to enable GNMA to perform its obligations under its guarantee.
 
     GNMA  Certificates.  Each GNMA Certificate held  in a Trust Fund (which may
be issued under  either the GNMA  I program  (each such certificate,  a 'GNMA  I
Certificate')  or  the  GNMA  II  program (each  such  certificate,  a  'GNMA II
Certificate'))  will  be   a  'fully   modified  pass-through'   mortgage-backed
certificate issued and serviced by a mortgage banking company or other financial
concern  ('GNMA Issuer') approved by GNMA or by FNMA as a seller-servicer of FHA
Loans and/or VA Loans. The mortgage loans underlying the GNMA Certificates  will
consist  of FHA Loans and/or  VA Loans. Each such mortgage  loan is secured by a
one-to four-family or  multifamily residential property.  GNMA will approve  the
issuance  of each such GNMA Certificate  in accordance with a guaranty agreement
(a 'Guaranty  Agreement') between  GNMA and  the GNMA  Issuer. Pursuant  to  its
Guaranty  Agreement, a GNMA Issuer will be  required to advance its own funds in
order to make timely payments of all  amounts due on each such GNMA  Certificate
if  the  payments received  by the  GNMA Issuer  on  the FHA  Loans or  VA Loans
underlying each such GNMA Certificate are less than the amounts due on each such
GNMA Certificate.
 
     The full  and timely  payment of  principal of  and interest  on each  GNMA
Certificate  will be guaranteed by GNMA, which  obligation is backed by the full
faith and credit of the United States.  Each such GNMA Certificate will have  an
original maturity of not more than 30 years (but may have original maturities of
substantially  less than 30 years). Each such  GNMA Certificate will be based on
and backed by a  pool of FHA Loans  or VA Loans secured  by one- to  four-family
residential  properties and will provide for the  payment by or on behalf of the
GNMA Issuer  to the  registered holder  of such  GNMA Certificate  of  scheduled
monthly  payments of  principal and  interest equal  to the  registered holder's
proportionate interest  in the  aggregate amount  of the  monthly principal  and
interest  payment on each FHA Loan or  VA Loan underlying such GNMA Certificate,
less the  applicable  servicing  and  guaranty fee,  which  together  equal  the
difference  between the interest on the FHA Loan or VA Loan and the pass-through
rate  on  the  GNMA  Certificate.   In  addition,  each  payment  will   include
proportionate  pass-through payments of any prepayments  of principal on the FHA
Loans or VA Loans underlying such  GNMA Certificate and liquidation proceeds  in
the  event of  a foreclosure or  other disposition of  any such FHA  Loans or VA
Loans.
 
     If a GNMA Issuer is unable to make the payments on a GNMA Certificate as it
becomes due, it must promptly notify GNMA and request GNMA to make such payment.
Upon notification and  request, GNMA  will make  such payments  directly to  the
registered holder of such GNMA Certificate. In the event no payment is made by a
GNMA  Issuer and the GNMA  Issuer fails to notify and  request GNMA to make such
payment, the holder  of such GNMA  Certificate will have  recourse only  against
GNMA to obtain such payment. The Trustee or its nominee, as registered holder of
the  GNMA Certificates  held in  a Trust  Fund, will  have the  right to proceed
directly against GNMA  under the terms  of the Guaranty  Agreements relating  to
such GNMA Certificates for any amounts that are not paid when due.
 
     All mortgage loans underlying a particular GNMA I Certificate must have the
same  interest rate (except for pools  of mortgage loans secured by manufactured
homes) over the term of the loan.  The interest rate on such GNMA I  Certificate
will  equal the  interest rate  on the  mortgage loans  included in  the pool of
mortgage loans  underlying such  GNMA I  Certificate, less  one-half  percentage
point per annum of the unpaid principal balance of the mortgage loans.
 
     Mortgage  loans underlying  a particular GNMA  II Certificate  may have per
annum interest rates that vary  from each other by  up to one percentage  point.
The  interest  rate  on  each  GNMA  II  Certificate  will  be  between one-half
percentage point and one and one-half  percentage points lower than the  highest
interest  rate on  the mortgage  loans included  in the  pool of  mortgage loans
underlying such GNMA II Certificate (except for pools of mortgage loans  secured
by manufactured homes).
 
     Regular  monthly installment  payments on each  GNMA Certificate  held in a
Trust Fund  will  be  comprised  of  interest due  as  specified  on  such  GNMA
Certificate  plus the scheduled principal payments on  the FHA Loans or VA Loans
underlying such GNMA Certificate due on the first day of the month in which  the
scheduled  monthly installments on  such GNMA Certificate  are due. Such regular
monthly installments on each  such GNMA Certificate are  required to be paid  to
the  Trustee as registered holder by the 15th day of each month in the case of a
GNMA I Certificate and are required to be mailed to the Trustee by the 20th  day
of each month in the case of a GNMA II Certificate. Any principal prepayments on
any  FHA Loans or VA Loans underlying a GNMA Certificate held in a Trust Fund or
any other early recovery of  principal on such loans  will be passed through  to
the Trustee as the registered holder of such GNMA Certificate.
 
                                       14

     GNMA  Certificates may be backed by  graduated payment mortgage loans or by
Buydown Loans for which funds will have been provided (and deposited into escrow
accounts) for application to the payment of a portion of the borrowers'  monthly
payments  during  the  early  years  of such  mortgage  loan.  Payments  due the
registered holders of GNMA Certificates backed by pools containing Buydown Loans
will be  computed  in  the same  manner  as  payments derived  from  other  GNMA
Certificates and will include amounts to be collected from both the borrower and
the  related escrow account.  The graduated payment  mortgage loans will provide
for graduated interest payments  that, during the early  years of such  mortgage
loans,  will be less than the amount  of stated interest on such mortgage loans.
The interest  not so  paid will  be added  to the  principal of  such  graduated
payment  mortgage loans  and, together  with interest  thereon, will  be paid in
subsequent years. The obligations of GNMA and of a GNMA Issuer will be the  same
irrespective  of whether the  GNMA Certificates are  backed by graduated payment
mortgage  loans  or  Buydown  Loans.  No  statistics  comparable  to  the  FHA's
prepayment  experience  on  level  payment,  non-'buydown'  mortgage  loans  are
available in respect of  graduated payment or  Buydown Loans. GNMA  Certificates
related to a Series of Certificates may be held in book-entry form.
 
     The  GNMA Certificates included in a Trust Fund, and the related underlying
mortgage  loans,  may  have  characteristics  and  terms  different  from  those
described  above. Any such different characteristics and terms will be described
in the related Prospectus Supplement.
 
     Federal  Home   Loan  Mortgage   Corporation.     FHLMC  is   a   corporate
instrumentality  of  the United  States  created pursuant  to  Title III  of the
Emergency Home Finance  Act of 1970,  as amended (the  'FHLMC Act'). The  common
stock  of FHLMC is owned by the Federal  Home Loan Banks and its preferred stock
is owned by stockholders of the  Federal Home Loan Banks. FHLMC was  established
primarily  for the purpose of increasing the availability of mortgage credit for
the financing of urgently needed housing. It seeks to provide an enhanced degree
of liquidity for residential mortgage investments primarily by assisting in  the
development  of  secondary  markets for  conventional  mortgages.  The principal
activity of FHLMC currently consists of the purchase of first lien  conventional
mortgage loans or participation interests in such mortgage loans and the sale of
the  mortgage  loans or  participations  so purchased  in  the form  of mortgage
securities, primarily FHLMC  Certificates. FHLMC is  confined to purchasing,  so
far as practicable, mortgage loans that it deems to be of such quality, type and
class   as  to  meet  generally  the   purchase  standards  imposed  by  private
institutional mortgage investors.
 
     FHLMC  Certificates.    Each  FHLMC  Certificate  represents  an  undivided
interest in a pool of mortgage loans that may consist of first lien conventional
loans,  FHA Loans or VA Loans  (a 'FHLMC Certificate group'). FHLMC Certificates
are sold under the  terms of a Mortgage  Participation Certificate Agreement.  A
FHLMC  Certificate may be issued under  either FHLMC's Cash Program or Guarantor
Program.
 
     Mortgage loans underlying the FHLMC Certificates held by a Trust Fund  will
consist  of mortgage loans with original terms  to maturity of between 10 and 40
years. Each such mortgage loan must  meet the applicable standards set forth  in
the  FHLMC Act. A FHLMC Certificate group may include whole loans, participation
interests  in  whole  loans  and  undivided  interests  in  whole  loans  and/or
participations  comprising another FHLMC Certificate  group. Under the Guarantor
Program, any  such FHLMC  Certificate  group may  include  only whole  loans  or
participation interests in whole loans.
 
     FHLMC  guarantees  to each  registered holder  of  a FHLMC  Certificate the
timely payment of interest on the underlying mortgage loans to the extent of the
applicable certificate interest rate on  the registered holder's pro rata  share
of  the unpaid principal balance outstanding on the underlying mortgage loans in
the FHLMC Certificate group  represented by such  FHLMC Certificate, whether  or
not  received.  FHLMC  also guarantees  to  each  registered holder  of  a FHLMC
Certificate collection  by  such  holder  of all  principal  on  the  underlying
mortgage  loans, without any offset or deduction, to the extent of such holder's
pro rata share thereof, but does not,  except if and to the extent specified  in
the  related Prospectus Supplement  for a Series  of Certificates, guarantee the
timely payment  of scheduled  principal. Under  FHLMC's Gold  PC Program,  FHLMC
guarantees  the timely payment of principal  based on the difference between the
pool factor published in the month  preceding the month of distribution and  the
pool factor published in such month of distribution. Pursuant to its guaranties,
FHLMC  indemnifies  holders  of  FHLMC Certificates  against  any  diminution in
principal  by  reason   of  charges  for   property  repairs,  maintenance   and
foreclosure.  FHLMC  may remit  the amount  due  on account  of its  guaranty of
collection of principal  at any  time after  default on  an underlying  mortgage
loan,  but not later than  (i) 30 days following  foreclosure sale, (ii) 30 days
following payment  of  the  claim by  any  mortgage  insurer or  (iii)  30  days
following the expiration of any right of redemption, whichever occurs later, but
in  any  event no  later  than one  year  after demand  has  been made  upon the
mortgagor for accelerated payment of principal. In taking actions regarding  the
collection  of principal  after default on  the mortgage  loans underlying FHLMC
Certificates, including the  timing of demand  for acceleration, FHLMC  reserves
the  right to exercise  its judgment with  respect to the  mortgage loans in the
same manner as for mortgage loans that it has purchased but not sold. The length
of
 
                                       15
 

<PAGE>
<PAGE>

time necessary for FHLMC to determine that a mortgage loan should be accelerated
varies with the particular  circumstances of each mortgagor,  and FHLMC has  not
adopted  standards which  require that the  demand be made  within any specified
period.
 
     FHLMC Certificates  are not  guaranteed  by the  United  States or  by  any
Federal  Home Loan Bank and do not constitute debts or obligations of the United
States or  any  Federal Home  Loan  Bank. The  obligations  of FHLMC  under  its
guaranty  are obligations solely of FHLMC and are not backed by, or entitled to,
the full faith and credit of the United States. If FHLMC were unable to  satisfy
such  obligations, distributions to holders  of FHLMC Certificates would consist
solely of payments and  other recoveries on the  underlying mortgage loans  and,
accordingly,  monthly distributions  to holders  of FHLMC  Certificates would be
affected by delinquent payments and defaults on such mortgage loans.
 
     Registered holders  of FHLMC  Certificates are  entitled to  receive  their
monthly  pro rata  share of  all principal  payments on  the underlying mortgage
loans received by FHLMC,  including any scheduled  principal payments, full  and
partial  prepayments of principal  and principal received by  FHLMC by virtue of
condemnation, insurance,  liquidation or  foreclosure,  and repurchases  of  the
mortgage  loans by FHLMC or the seller  thereof. FHLMC is required to remit each
registered FHLMC certificateholder's pro rata share of principal payments on the
underlying mortgage loans, interest at the FHLMC pass-through rate and any other
sums such as prepayment fees, within 60 days of the date on which such  payments
are deemed to have been received by FHLMC.
 
     Under  FHLMC's Cash Program, there is no  limitation on the amount by which
interest rates on the mortgage loans  underlying a FHLMC Certificate may  exceed
the  pass-through  rate  on the  FHLMC  Certificate. Under  such  program, FHLMC
purchases groups of whole mortgage  loans from sellers at specified  percentages
of  their unpaid principal  balances, adjusted for  accrued or prepaid interest,
which when applied to the interest rate of the mortgage loans and participations
purchased results in the  yield (expressed as a  percentage) required by  FHLMC.
The  required  yield, which  includes a  minimum servicing  fee retained  by the
servicer, is calculated using  the outstanding principal  balance. The range  of
interest  rates on the mortgage loans  and participations in a FHLMC Certificate
group under the Cash Program will  vary since mortgage loans and  participations
are  purchased and assigned to a FHLMC  Certificate group based upon their yield
to FHLMC rather  than on  the interest rate  on the  underlying mortgage  loans.
Under FHLMC's Guarantor Program, the pass-through rate on a FHLMC Certificate is
established  based  upon the  lowest interest  rate  on the  underlying mortgage
loans, minus a minimum  servicing fee and the  amount of FHLMC's management  and
guaranty income as agreed upon between the seller and FHLMC.
 
     FHLMC  Certificates  duly presented  for  registration of  ownership  on or
before the last business day of a month are registered effective as of the first
day of  the month.  The  first remittance  to a  registered  holder of  a  FHLMC
Certificate will be distributed so as to be received normally by the 15th day of
the  second month following the month in which the purchaser became a registered
holder  of  such  FHLMC  Certificate.   Thereafter,  such  remittance  will   be
distributed  monthly to the registered  holder so as to  be received normally by
the 15th day  of each  month. The  Federal Reserve  Bank of  New York  maintains
book-entry accounts with respect to FHLMC Certificates sold by FHLMC on or after
January  2, 1985, and makes payments of principal and interest each month to the
registered holders thereof in accordance with such holders' instructions.
 
     Federal National Mortgage Association.   FNMA is a federally chartered  and
privately  owned corporation organized  and existing under  the Federal National
Mortgage Association Charter Act, as amended. FNMA was originally established in
1938 as a United States government  agency to provide supplemental liquidity  to
the   mortgage  market  and   was  transformed  into   a  stockholder-owned  and
privately-managed corporation by legislation enacted in 1968.
 
     FNMA provides funds to the mortgage market primarily by purchasing mortgage
loans from lenders,  thereby replenishing  their funds  for additional  lending.
FNMA  acquires  funds  to  purchase  mortgage  loans  from  many  capital market
investors that may  not ordinarily  invest in mortgages,  thereby expanding  the
total amount of funds available for housing. Operating nationwide, FNMA helps to
redistribute mortgage funds from capital-surplus to capital-short areas.
 
     FNMA  Certificates.  FNMA Certificates are Guaranteed Mortgage Pass-Through
Certificates representing fractional undivided interests  in a pool of  mortgage
loans  formed by FNMA. Each mortgage loan  must meet the applicable standards of
the FNMA purchase program. Mortgage loans comprising a pool are either  provided
by FNMA from its own portfolio or purchased pursuant to the criteria of the FNMA
purchase program.
 
     Mortgage  loans  underlying FNMA  Certificates held  by  a Trust  Fund will
consist of  conventional  mortgage  loans,  FHA  Loans  or  VA  Loans.  Original
maturities   of   substantially   all  of   the   conventional,   level  payment
 
                                       16
 

<PAGE>
<PAGE>

mortgage loans underlying a FNMA Certificate are expected to be between either 8
to 15 years or 20 to 40  years. The original maturities of substantially all  of
the fixed rate, level payment FHA Loans or VA Loans are expected to be 30 years.
 
     Mortgage loans underlying a FNMA Certificate may have annual interest rates
that  vary by  as much  as two percentage  points from  each other.  The rate of
interest payable on a FNMA Certificate is  equal to the lowest interest rate  of
any  mortgage  loan  in  the  related  pool,  less  a  specified  minimum annual
percentage representing servicing compensation and FNMA's guaranty fee. Under  a
regular servicing option (pursuant to which the mortgagee or each other servicer
assumes the entire risk of foreclosure losses), the annual interest rates on the
mortgage loans underlying a FNMA Certificate will be between 50 basis points and
250  basis  points greater  than is  its  annual pass-through  rate and  under a
special servicing option  (pursuant to which  FNMA assumes the  entire risk  for
foreclosure  losses), the annual interest rates on the mortgage loans underlying
a FNMA  Certificate will  generally be  between 55  basis points  and 255  basis
points  greater than the annual FNMA Certificate pass-through rate. If specified
in the  related  Prospectus  Supplement,  FNMA Certificates  may  be  backed  by
adjustable rate mortgages.
 
     FNMA  guarantees to  each registered holder  of a FNMA  Certificate that it
will distribute  amounts  representing  such  holder's  proportionate  share  of
scheduled  principal and interest  payments at the  applicable pass-through rate
provided for by such FNMA Certificate on the underlying mortgage loans,  whether
or  not received,  and such holder's  proportionate share of  the full principal
amount of any foreclosed or other  finally liquidated mortgage loan, whether  or
not  such principal amount is actually  recovered. The obligations of FNMA under
its guaranties are obligations solely of FNMA and are not backed by, or entitled
to, the full faith and  credit of the United  States. Although the Secretary  of
the Treasury of the United States has discretionary authority to lend FNMA up to
$2.25  billion outstanding at any time, neither the United States nor any agency
thereof is obligated to finance FNMA's operations or to assist FNMA in any other
manner. If FNMA were unable to satisfy its obligations, distributions to holders
of FNMA Certificates would  consist solely of payments  and other recoveries  on
the underlying mortgage loans and, accordingly, monthly distributions to holders
of  FNMA Certificates would  be affected by delinquent  payments and defaults on
such mortgage loans.
 
     FNMA Certificates evidencing interests in pools of mortgage loans formed on
or after May 1,  1985 (other than FNMA  Certificates backed by pools  containing
graduated  payment  mortgage  loans  or mortgage  loans  secured  by multifamily
projects) are available in book-entry form only. Distributions of principal  and
interest  on each FNMA Certificate will be made  by FNMA on the 25th day of each
month to the persons in whose name the FNMA Certificate is entered in the  books
of  the Federal Reserve Banks (or registered on the FNMA Certificate register in
the case of fully registered FNMA Certificates)  as of the close of business  on
the last day of the preceding month. With respect to FNMA Certificates issued in
book-entry form, distributions thereon will be made by wire, and with respect to
fully registered FNMA Certificates, distributions thereon will be made by check.
 
     The  FNMA Certificates included in a Trust Fund, and the related underlying
mortgage  loans,  may  have  characteristics  and  terms  different  from  those
described  above. Any such different characteristics and terms will be described
in the related Prospectus Supplement.
 
     Stripped Mortgage-Backed Securities.  Agency Securities may consist of  one
or more stripped mortgage-backed securities, each as described herein and in the
related  Prospectus  Supplement. Each  such  Agency Security  will  represent an
undivided interest in all or part of either the principal distributions (but not
the interest distributions) or the interest distributions (but not the principal
distributions), or  in some  specified  portion of  the principal  and  interest
distributions (but not all of such distributions) on certain FHLMC, FNMA or GNMA
Certificates.  The underlying securities will be held under a trust agreement by
FHLMC, FNMA or GNMA, each as trustee, or by another trustee named in the related
Prospectus Supplement. FHLMC, FNMA or  GNMA will guarantee each stripped  Agency
Security  to the same extent as such entity guarantees the underlying securities
backing such stripped Agency Security, unless otherwise specified in the related
Prospectus Supplement.
 
     Other  Agency  Securities.    If   specified  in  the  related   Prospectus
Supplement,  a Trust Fund  may include other  mortgage pass-through certificates
issued or guaranteed  by GNMA, FNMA  or FHLMC. The  characteristics of any  such
mortgage   pass-through  certificates  will  be  described  in  such  Prospectus
Supplement. If  so  specified,  a  combination  of  different  types  of  Agency
Securities may be held in a Trust Fund.
 
PRIVATE MORTGAGE-BACKED SECURITIES
 
     Private Mortgage-Backed Securities may consist of (a) mortgage pass-through
certificates or participation certificates evidencing an undivided interest in a
pool of mortgage loans or (b) collateralized mortgage
 
                                       17

obligations  secured by  mortgage loans. Private  Mortgage-Backed Securities may
include stripped mortgage-backed securities  representing an undivided  interest
in  all or a  part of either  the principal distributions  (but not the interest
distributions)  or   the  interest   distributions   (but  not   the   principal
distributions)  or  in  some specified  portion  of the  principal  and interest
distributions (but not  all of  such distributions) on  certain mortgage  loans.
Private  Mortgage-Backed Securities will have been  issued pursuant to a pooling
and servicing agreement, an indenture or similar agreement (a 'PMBS Agreement').
Unless  otherwise   specified  in   the  related   Prospectus  Supplement,   the
seller/servicer of the underlying mortgage loans will have entered into the PMBS
Agreement  with the trustee under such  PMBS Agreement (the 'PMBS Trustee'). The
PMBS Trustee  or its  agent, or  a custodian,  will possess  the mortgage  loans
underlying  such Private  Mortgage-Backed Security. Mortgage  loans underlying a
Private Mortgage-Backed  Security will  be  serviced by  a servicer  (the  'PMBS
Servicer')  directly or by  one or more  subservicers who may  be subject to the
supervision of the PMBS Servicer.
 
     The issuer of  the Private Mortgage-Backed  Securities (the 'PMBS  Issuer')
will  be  a  financial institution  or  other  entity engaged  generally  in the
business of mortgage  lending, a public  agency or instrumentality  of a  state,
local  or federal government, or a limited purpose corporation organized for the
purpose of, among other  things, establishing trusts  and acquiring and  selling
housing loans to such trusts and selling beneficial interests in such trusts. If
so  specified in the  related Prospectus Supplement,  the PMBS Issuer  may be an
affiliate of the Depositor. The obligations of the PMBS Issuer will generally be
limited to certain  representations and  warranties with respect  to the  assets
conveyed  by it  to the  related Trust Fund.  Unless otherwise  specified in the
related Prospectus Supplement, the PMBS Issuer  will not have guaranteed any  of
the   assets  conveyed  to  the  related  Trust  Fund  or  any  of  the  Private
Mortgage-Backed  Securities  issued  under  the  PMBS  Agreement.  Additionally,
although  the mortgage  loans underlying the  Private Mortgage-Backed Securities
may be guaranteed  by an  agency or instrumentality  of the  United States,  the
Private Mortgage-Backed Securities themselves will not be so guaranteed.
 
     Distributions  of  principal  and  interest will  be  made  on  the Private
Mortgage-Backed Securities  on the  dates specified  in the  related  Prospectus
Supplement.  The Private Mortgage-Backed  Securities may be  entitled to receive
nominal or no principal distributions  or nominal or no interest  distributions.
Principal and interest distributions will be made on the Private Mortgage-Backed
Securities by the PMBS Trustee or the PMBS Servicer. The PMBS Issuer or the PMBS
Servicer  may  have  the  right  to  repurchase  assets  underlying  the Private
Mortgage-Backed Securities after  a certain  date or  under other  circumstances
specified in the related Prospectus Supplement.
 
     The  mortgage loans  underlying the Private  Mortgage-Backed Securities may
consist of  fixed  rate, level  payment,  fully amortizing  loans  or  graduated
payment  mortgage loans, Buydown Loans, adjustable  rate mortgage loans or loans
having balloon or  other special payment  features. Such mortgage  loans may  be
secured by single family property or multifamily property or by an assignment of
the  proprietary lease  or occupancy agreement  relating to  a specific dwelling
within a Cooperative and the related shares issued by such Cooperative.
 
     The Prospectus Supplement for  a Series for which  the Trust Fund  includes
Private  Mortgage-Backed Securities  will specify (i)  the aggregate approximate
principal amount  and  type of  the  Private Mortgage-Backed  Securities  to  be
included  in the Trust Fund; (ii)  certain characteristics of the mortgage loans
that comprise the underlying assets  for the Private Mortgage-Backed  Securities
including  (A) the payment features of  such mortgage loans, (B) the approximate
aggregate principal balance, if known,  of underlying mortgage loans insured  or
guaranteed by a governmental entity, (C) the servicing fee or range of servicing
fees  with respect to the mortgage loans  and (D) the minimum and maximum stated
maturities of the underlying  mortgage loans at  origination; (iii) the  maximum
original term-to-stated maturity of the Private Mortgage-Backed Securities; (iv)
the  weighted  average term-to-stated  maturity  of the  Private Mortgage-Backed
Securities;  (v)  the   pass-through  or   certificate  rate   of  the   Private
Mortgage-Backed   Securities;   (vi)  the   weighted  average   pass-through  or
certificate rate  of  the Private  Mortgage-Backed  Securities; (vii)  the  PMBS
Issuer,  the PMBS Servicer (if other than  the PMBS Issuer) and the PMBS Trustee
for such Private Mortgage-Backed  Securities; (viii) certain characteristics  of
credit support, if any, such as reserve funds, insurance policies, surety bonds,
letters  of credit or  guaranties relating to the  mortgage loans underlying the
Private Mortgage-Backed Securities or to such Private Mortgage-Backed Securities
themselves; (ix)  the terms  on which  the underlying  mortgage loans  for  such
Private  Mortgage-Backed Securities may, or are  required to, be purchased prior
to their stated maturity or the  stated maturity of the Private  Mortgage-Backed
Securities;  and (x) the  terms on which  mortgage loans may  be substituted for
those originally underlying the Private Mortgage-Backed Securities.

SUBSTITUTION OF MORTGAGE ASSETS
 
     Substitution of Mortgage Assets will be permitted in the event of  breaches
of representations and warranties with respect to any original Mortgage Asset or
in  the event the documentation with respect to any Mortgage Asset is determined
by the Trustee to be incomplete. The period during which such substitution  will
be  permitted generally will be indicated  in the related Prospectus Supplement.
The related Prospectus Supplement will describe any other conditions upon  which
Mortgage Assets may be substituted for Mortgage Assets initially included in the
Trust Fund.
 
                                USE OF PROCEEDS
 
     The  net proceeds to be received from  the sale of the Certificates will be
applied by the Depositor to the purchase  of Mortgage Assets or will be used  by
the  Depositor for  general corporate  purposes. The  Depositor expects  to sell
Certificates in Series from time to time, but the timing and amount of offerings
of Certificates will  depend on  a number of  factors, including  the volume  of
Mortgage   Assets  acquired   by  the  Depositor,   prevailing  interest  rates,
availability of funds and general market conditions.
 
                                 THE DEPOSITOR
 
     CWMBS, Inc., a Delaware corporation (the 'Depositor'), was organized on May
27, 1993 for the limited purpose of acquiring, owning and transferring  Mortgage
Assets  and selling interests therein or bonds secured thereby. The Depositor is
a subsidiary of Countrywide Credit Industries, Inc., a Delaware corporation. The
Depositor maintains its  principal office  at 155 North  Lake Avenue,  Pasadena,
California 91101-7139. Its telephone number is (818) 584-3547.
 
     Neither  the Depositor nor any of the Depositor's affiliates will ensure or
guarantee distributions on the Certificates of any Series.
 
                             MORTGAGE LOAN PROGRAM
 
     The Mortgage  Loans  will have  been  purchased by  the  Depositor,  either
directly  or through affiliates, from Sellers. Unless otherwise specified in the
related Prospectus Supplement, the Mortgage  Loans so acquired by the  Depositor
will have been originated in accordance with the underwriting criteria specified
below under 'Underwriting Standards'.
 
UNDERWRITING STANDARDS
 
     Unless  otherwise  specified  in the  related  Prospectus  Supplement, each
Seller will represent and warrant that all Mortgage 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
Mortgage Loan insured by the FHA or  partially guaranteed by the VA, the  Seller
will represent that it has complied with underwriting policies of the FHA or the
VA, as the case may be.
 
     Underwriting  standards are applied by or on behalf of a lender to evaluate
the borrower's credit standing and repayment ability, and the value and adequacy
of the  mortgaged property  as collateral.  In general,  a prospective  borrower
applying  for a  mortgage loan  is required to  fill out  a detailed application
designed to provide to the underwriting officer pertinent credit information. As
part of  the description  of the  borrower's financial  condition, the  borrower
generally  is required to provide a current list of assets and liabilities and a
statement of income and  expenses, as well  as an authorization  to apply for  a
credit  report  which  summarizes  the  borrower's  credit  history  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  the  length  of  employment  with that
organization, the borrower's current salary and whether it is expected that  the
borrower  will continue such employment in the future. If a prospective borrower
is self-employed, the borrower  may be required to  submit copies of signed  tax
returns. The borrower may also be required to authorize verification of deposits
at financial institutions where the borrower has demand or savings accounts.
 
     In  determining the  adequacy of the  mortgaged property  as collateral, an
appraisal is made of  each property considered for  financing. The appraiser  is
required  to inspect the property and verify that  it is in good repair and that
construction, if new, has been completed.  The appraisal is based on the  market
value of comparable homes, the estimated rental income (if considered applicable
by the appraiser) and the cost of replacing the home.
 
                                       19
 

<PAGE>
<PAGE>

     Once   all  applicable  employment,  credit  and  property  information  is
received, a  determination  generally is  made  as to  whether  the  prospective
borrower  has sufficient  monthly income  available (i)  to meet  the borrower's
monthly obligations on the proposed  mortgage loan (generally determined on  the
basis of the monthly payments due in the year of origination) and other expenses
related  to the mortgaged property (such as property taxes and hazard insurance)
and (ii) to meet  monthly housing expenses and  other financial obligations  and
monthly   living  expenses.  The  underwriting  standards  applied  by  Sellers,
particularly with respect to the level of loan documentation and the mortgagor's
income and credit history, may be varied in appropriate cases where factors such
as low Loan-to-Value Ratios or other favorable credit exist.
 
     In the case  of a Mortgage  Loan secured  by a leasehold  interest in  real
property,  the title to which  is held by a third  party lessor, the Seller will
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
Mortgage Note.
 
     Certain of the types of Mortgage Loans that may be included in a Trust Fund
are recently developed and may  involve additional uncertainties not present  in
traditional  types of  loans. For  example, certain  of such  Mortgage Loans may
provide for escalating  or variable payments  by the Mortgagor.  These types  of
Mortgage  Loans are underwritten on the basis  of a judgment that the Mortgagors
have the  ability to  make  the monthly  payments  required initially.  In  some
instances,  however,  a  Mortgagor's  income may  not  be  sufficient  to permit
continued loan payments as such payments increase. These types of Mortgage Loans
may also be  underwritten primarily upon  the basis of  Loan-to-Value Ratios  or
other favorable credit factors.
 
QUALIFICATIONS OF SELLERS
 
     Unless  otherwise  specified  in the  related  Prospectus  Supplement, each
Seller will be  required to satisfy  the qualifications set  forth herein.  Each
Seller  must be an institution experienced in originating and servicing mortgage
loans of the  type contained  in the related  Mortgage Pool  in accordance  with
accepted  practices  and  prudent  guidelines,  and  must  maintain satisfactory
facilities to originate and service those mortgage loans. Each Seller must be  a
seller/servicer  approved  by  either  FNMA  or FHLMC.  Each  Seller  must  be a
mortgagee approved by the  FHA or an institution  the deposit accounts in  which
are  insured by the Federal Deposit  Insurance Corporation. The Resolution Trust
Corporation, acting in its capacity as  conservator or receiver of a  depository
institution,  may  be  a  Seller  if  so  specified  in  the  related Prospectus
Supplement.
 
REPRESENTATIONS BY SELLERS; REPURCHASES
 
     Each Seller will have made representations and warranties in respect of the
Mortgage Loans sold by  such Seller and evidenced  by a Series of  Certificates.
Such  representations and  warranties unless  otherwise provided  in the related
Prospectus Supplement  generally include,  among other  things: (i)  that  title
insurance  (or in the case  of Mortgaged Properties located  in areas where such
policies are generally not  available, an attorney's  certificate of title)  and
any  required hazard insurance policy and Primary Mortgage Insurance Policy were
effective at the origination of each Mortgage Loan other than Cooperative Loans,
and that each policy (or certificate of title as applicable) remained in  effect
on  the date of purchase of the Mortgage Loan from the Seller by or on behalf of
the Depositor; (ii) that the  Seller had good title  to each such Mortgage  Loan
and  such Mortgage  Loan was subject  to no offsets,  defenses, counterclaims or
rights of rescission except to the  extent that any buydown agreement  described
herein may forgive certain indebtedness of a Mortgagor; (iii) that each Mortgage
Loan  constituted a valid first lien on,  or a first perfected security interest
with respect  to, the  Mortgaged  Property (subject  only to  permissible  title
insurance  exceptions, if applicable, and  certain other exceptions described in
the Agreement) and that the Mortgaged Property  was free from damage and was  in
good  repair; (iv) that there were no delinquent tax or assessment liens against
the Mortgaged Property; (v) that no required payment on a Mortgage Loan was more
than 31  days delinquent  at any  time during  the twelve  months prior  to  the
Cut-off  Date; and (vi) that each Mortgage 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 Mortgage Loan will be made not as  of
the  Cut-off Date but as of the date on which such Seller sold the Mortgage Loan
to the  Depositor  or  one  of  its  affiliates.  Under  such  circumstances,  a
substantial  period of time may  have elapsed between such  date and the date of
initial issuance of the  Series of Certificates evidencing  an interest in  such
Mortgage  Loan.  Since the  representations and  warranties of  a Seller  do not
address events that  may occur following  the sale  of a Mortgage  Loan by  such
Seller, its repurchase obligation described below will not arise if the relevant
event that would otherwise have given rise to such an obligation with respect to
a  Mortgage Loan  occurs after the  date of sale  of such Mortgage  Loan by such
Seller to  the Depositor  or its  affiliates. However,  the Depositor  will  not
include   any   Mortgage   Loan  in   the   Trust   Fund  for   any   Series  of
 
                                       20
 

<PAGE>
<PAGE>

Certificates 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 Mortgage  Loan
as of the date of initial issuance of the related Series of Certificates. If the
Master  Servicer is also a Seller of Mortgage Loans with respect to a particular
Series, such  representations will  be in  addition to  the representations  and
warranties made by the Master Servicer in its capacity as the Master Servicer.
 
     The  Master Servicer or the Trustee, if  the Master Servicer is the Seller,
will promptly notify the relevant Seller of any breach of any representation  or
warranty  made by it in respect of a Mortgage Loan that materially and adversely
affects the interests of  the Certificateholders in  such Mortgage Loan.  Unless
otherwise  specified in the related Prospectus Supplement, if such Seller cannot
cure such breach within  90 days after  notice from the  Master Servicer or  the
Trustee,  as the case may  be, then such Seller  will be obligated to repurchase
such Mortgage Loan from the Trust Fund  at a price (the 'Purchase Price')  equal
to  100% of  the outstanding  principal balance  thereof as  of the  date of the
repurchase plus accrued interest thereon to the first day of the month in  which
the  Purchase  Price  is  to  be distributed  at  the  Mortgage  Rate  (less any
unreimbursed Advances or amount payable as related servicing compensation if the
Seller is the Master Servicer  with respect to such  Mortgage Loan). If a  REMIC
election  is to be made with respect  to a Trust Fund, unless otherwise provided
in the related  Prospectus Supplement, the  Master Servicer or  a holder of  the
related residual certificate will be obligated to pay any prohibited transaction
tax  that may arise in connection with any such repurchase. The Master Servicer,
unless otherwise  specified  in  the  related  Prospectus  Supplement,  will  be
entitled  to reimbursement for any  such payment from the  assets of the related
Trust Fund  or  from  any  holder  of  the  related  residual  certificate.  See
'Description  of  the  Certificates  --  General'  herein  and  in  the  related
Prospectus Supplement. 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
Certificateholders, following the practices  it would employ  in its good  faith
business  judgment  were it  the owner  of such  Mortgage Loan.  This repurchase
obligation will constitute  the sole remedy  available to Certificateholders  or
the Trustee for a breach of representation by a Seller.
 
     Neither  the Depositor nor the Master  Servicer (unless the Master Servicer
is the  Seller) will  be  obligated to  purchase a  Mortgage  Loan if  a  Seller
defaults  on its obligation to do so, and no assurance can be given that Sellers
will carry out their respective repurchase obligations with respect to  Mortgage
Loans.  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 obligation  as described
below under  'The Pooling  and  Servicing Agreement  -- Assignment  of  Mortgage
Assets'.
 
                        DESCRIPTION OF THE CERTIFICATES
 
     Each  Series of Certificates will be issued pursuant to an Agreement, dated
as of the related Cut-off Date, among the Depositor, the Master Servicer and the
Trustee for the benefit of the holders  of the Certificates of such Series.  The
provisions  of  each  Agreement  will  vary depending  upon  the  nature  of the
Certificates to be issued thereunder and the nature of the related Trust Fund. A
form of an Agreement is an exhibit  to the Registration Statement of which  this
Prospectus  is a part. The following  summaries describe certain provisions that
may appear  in  each  Agreement.  The Prospectus  Supplement  for  a  Series  of
Certificates  will  describe any  provision of  the  Agreement relating  to such
Series that materially differs  from the description  thereof contained in  this
Prospectus.  The summaries do not purport to be complete and are subject to, and
are qualified in their entirety  by reference to, all  of the provisions of  the
Agreement  for  each  Series  of  Certificates  and  the  applicable  Prospectus
Supplement. The  Depositor  will  provide  a  copy  of  the  Agreement  (without
exhibits) relating to any Series without charge upon written request of a holder
of  record of a Certificate  of such Series addressed  to CWMBS, Inc., 155 North
Lake Avenue, Pasadena, California 91101-7139, Attention: Secretary.
 
GENERAL
 
     Unless otherwise specified in  the Prospectus Supplement, the  Certificates
of  each Series will be issued in  either fully registered or book-entry form in
the authorized  denominations specified  in the  related Prospectus  Supplement,
will evidence specified beneficial ownership interests in the related Trust Fund
created  pursuant to the related Agreement and  will not be entitled to payments
in respect of the  assets included in  any other Trust  Fund established by  the
Depositor.  The Certificates will not represent  obligations of the Depositor or
any affiliate  of the  Depositor. The  Mortgage Assets  will not  be insured  or
guaranteed  by  any  governmental  entity  or  other  person,  unless  otherwise
specified in the related Prospectus Supplement. Each Trust Fund will consist of,
to the extent provided  in the related Agreement,  (i) the Mortgage Assets  that
from time to time are subject to the related Agreement (exclusive of any amounts
specified    in    the    related   Prospectus    Supplement    (the   'Retained
 
                                       21

Interest')); (ii) such assets as from time to time are required to be  deposited
in  the related Certificate Account; (iii) property that secured a Mortgage Loan
and that is acquired on behalf of the Certificateholders by foreclosure or  deed
in  lieu of foreclosure;  and (iv) any Primary  Mortgage Insurance Policies, FHA
Insurance and VA Guaranties, and any other 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 Mortgage  Assets, a  reserve fund, a  mortgage pool  insurance policy,  a
special  hazard  insurance policy,  a bankruptcy  bond, one  or more  letters of
credit, a surety bond, guaranties or similar instruments or other agreements.
 
     Each Series of  Certificates will be  issued in one  or more classes.  Each
class  of  Certificates of  a  Series will  evidence  beneficial ownership  of a
specified percentage (which may  be 0%) or portion  of future interest  payments
and  a specified  percentage (which  may be 0%)  or portion  of future principal
payments on  the  Mortgage  Assets  in  the related  Trust  Fund.  A  Series  of
Certificates may include one or more classes that are senior in right to payment
to  one or more other classes of  Certificates of such Series. Certain Series or
classes of Certificates may  be covered by insurance  policies, surety bonds  or
other  forms of credit enhancement, in each  case as described herein and in the
related Prospectus Supplement. One or more  classes of Certificates of a  Series
may  be  entitled  to  receive  distributions  of  principal,  interest  or  any
combination thereof.  Distributions  on one  or  more  classes of  a  Series  of
Certificates  may  be  made  prior  to one  or  more  other  classes,  after the
occurrence of specified events, in accordance with a schedule or formula, on the
basis of collections  from designated  portions of  the Mortgage  Assets in  the
related  Trust Fund, or on  a different basis, in each  case as specified in the
related Prospectus Supplement. The timing and amounts of such distributions  may
vary  among  classes  or  over  time  as  specified  in  the  related Prospectus
Supplement.
 
     Unless  otherwise   specified  in   the  related   Prospectus   Supplement,
distributions of principal and interest (or, where applicable, of principal only
or  interest only) on  the related Certificates  will be made  by the Trustee on
each Distribution Date (i.e., monthly, quarterly, semi-annually or at such other
intervals and on  the dates as  are specified in  the Prospectus Supplement)  in
proportion  to the percentages  specified in the  related Prospectus Supplement.
Distributions will be made  to the persons in  whose names the Certificates  are
registered  at  the close  of business  on  the dates  specified in  the related
Prospectus Supplement (each,  a 'Record  Date'). Distributions will  be made  by
check  or money  order mailed  to the  persons entitled  thereto at  the address
appearing  in  the  register  maintained   for  holders  of  Certificates   (the
'Certificate  Register') or, if specified  in the related Prospectus Supplement,
in the case  of Certificates that  are of a  certain minimum denomination,  upon
written  request by  the Certificateholder,  by wire  transfer or  by such other
means as are described therein;  provided, however, that the final  distribution
in  retirement  of the  Certificates  will be  made  only upon  presentation and
surrender of the Certificates at  the office or agency  of the Trustee or  other
person specified in the notice to Certificateholders of such final distribution.
 
     The  Certificates  will  be  freely transferable  and  exchangeable  at the
Corporate Trust Office  of the Trustee  as set forth  in the related  Prospectus
Supplement.  No service charge will be made  for any registration of exchange or
transfer of Certificates of any Series, but the Trustee may require payment of a
sum sufficient to cover any related tax or other governmental charge.
 
     Under current law the purchase and holding by or on behalf of any  employee
benefit  plan or  other retirement arrangement  (including individual retirement
accounts and annuities,  Keogh plans  and collective investment  funds in  which
such  plans, accounts  or arrangements  are invested)  subject to  provisions of
ERISA or  the Code  of a  class of  Certificates entitled  only to  a  specified
percentage  of payments of either interest or  principal or a notional amount of
either interest  or principal  on the  related  Mortgage Assets  or a  class  of
Certificates  entitled  to receive  payments of  interest  and principal  on the
Mortgage Assets only after payments to other classes or after the occurrence  of
certain  specified  events may  result in  'prohibited transactions'  within the
meaning of  ERISA  and  the  Code. See  'ERlSA  Considerations'  herein.  Unless
otherwise   specified  in   the  related  Prospectus   Supplement,  transfer  of
Certificates of such a  class will not be  registered unless the transferee  (i)
represents  that it is not,  and is not purchasing on  behalf of, any such plan,
account or arrangement or  (ii) provides an opinion  of counsel satisfactory  to
the  Trustee and the Depositor that the purchase of Certificates of such a class
by or  on behalf  of such  plan,  account or  arrangement is  permissible  under
applicable  law and  will not  subject the Trustee,  the Master  Servicer or the
Depositor to any obligation or liability in addition to those undertaken in  the
Agreement.
 
     As  to each Series, an election may be made to treat the related Trust Fund
or designated portions thereof as 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
 
                                       22

may be made only if certain conditions are satisfied. As to any such Series, the
terms  and provisions applicable to  the making of a  REMIC election, as well as
any material federal income tax consequences to Certificateholders not otherwise
described herein, will  be set forth  in the related  Prospectus Supplement.  If
such  an election is made with  respect to a Series, one  of the classes will be
designated as evidencing the sole class  of 'residual interests' in the  related
REMIC,  as defined  in the  Code. All  other classes  of Certificates  in such a
Series will constitute 'regular interests' in  the related REMIC, as defined  in
the  Code. As to  each Series with  respect to which  a REMIC election  is to be
made, 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 specified in the related Prospectus
Supplement,  will be  entitled to  reimbursement for  any such  payment from the
assets of the Trust Fund or from any holder of the related residual certificate.
 
DISTRIBUTIONS ON CERTIFICATES
 
     General.  In general, the method of determining the amount of distributions
on a  particular  Series of  Certificates  will depend  on  the type  of  credit
support,  if  any,  that  is  used with  respect  to  such  Series.  See 'Credit
Enhancement' herein and in  the related Prospectus  Supplement. Set forth  below
are  descriptions of various methods that may be used to determine the amount of
distributions on  the  Certificates  of  a  particular  Series.  The  Prospectus
Supplement  for each Series of Certificates will  describe the method to be used
in determining the amount of distributions on the Certificates of such Series.
 
     Distributions allocable to  principal of and  interest on the  Certificates
will  be made by  the Trustee out  of, and only  to the extent  of, funds in the
related Certificate Account,  including any funds  transferred from any  Reserve
Fund.  As between Certificates of different classes and as between distributions
of principal (and, if applicable, between distributions of Principal Prepayments
and scheduled payments  of principal)  and interest, distributions  made on  any
Distribution  Date  will  be  applied as  specified  in  the  related Prospectus
Supplement. Unless  otherwise specified  in the  related Prospectus  Supplement,
distributions  to  any  class of  Certificates  will  be made  pro  rata  to all
Certificateholders of that class.
 
     Available Funds.  All distributions on  the Certificates of each Series  on
each Distribution Date will be made from the Available Funds, in accordance with
the  terms described in  the related Prospectus Supplement  and specified in the
Agreement. Unless  otherwise  provided  in the  related  Prospectus  Supplement,
'Available  Funds' for each Distribution Date will generally equal the amount on
deposit in the  related Certificate 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.   Unless  otherwise  specified in  the  related
Prospectus Supplement, interest will accrue on the aggregate Certificate Balance
(or,  in the  case of Certificates  entitled only to  distributions allocable to
interest, the  aggregate notional  amount) of  each class  of Certificates  (the
'Class  Certificate  Balance') entitled  to  interest at  the  Pass-Through Rate
(which may be a fixed rate or a rate adjustable as specified in such  Prospectus
Supplement)  from  the date  and for  the periods  specified in  such Prospectus
Supplement. To the extent funds are available therefor, interest accrued  during
each  such specified period  on each class of  Certificates entitled to interest
(other than a class of Certificates that provides for interest that accrues, but
is not currently payable, referred to hereafter as 'Accrual Certificates')  will
be  distributable on the Distribution Dates  specified in the related Prospectus
Supplement  until  the  Class  Certificate  Balance  of  such  class  has   been
distributed   in  full  or,  in  the  case  of  Certificates  entitled  only  to
distributions allocable to interest, until the aggregate notional amount of such
Certificates is reduced  to zero or  for the  period of time  designated in  the
related   Prospectus  Supplement.  The  original  Certificate  Balance  of  each
Certificate will equal  the aggregate  distributions allocable  to principal  to
which  such Certificate is  entitled. Unless otherwise  specified in the related
Prospectus Supplement, distributions allocable  to interest on each  Certificate
that  is not entitled to distributions allocable to principal will be calculated
based on  the notional  amount of  such Certificate.  The notional  amount of  a
Certificate  will not  evidence an interest  in or  entitlement to distributions
allocable to principal but will be used solely for convenience in expressing the
calculation of interest and for certain other purposes.
 
     With respect to any  class of Accrual Certificates,  any interest that  has
accrued  but is not paid on a given Distribution Date will be added to the Class
Certificate Balance of  such class  of Certificates on  that Distribution  Date.
Unless  otherwise specified in the  related Prospectus Supplement, distributions
of interest on each class of  Accrual Certificates will commence only after  the
occurrence  of the events specified in  such Prospectus Supplement and, prior to
such  time,  the  beneficial  ownership  interest  of  such  class  of   Accrual
Certificates in the Trust Fund, as reflected in the Class Certificate Balance of
such  class of Accrual Certificates, will  increase on each Distribution Date by
the amount of interest that accrued on such class of Accrual Certificates during
the
 
                                       23
 

<PAGE>
<PAGE>

preceding interest accrual period but that was not required to be distributed to
such class on  such Distribution Date.  Any such class  of Accrual  Certificates
will  thereafter accrue interest on its outstanding Class Certificate Balance as
so adjusted.
 
     Distributions of  Principal.   Unless otherwise  specified in  the  related
Prospectus   Supplement,  the  Class   Certificate  Balance  of   any  class  of
Certificates entitled to distributions of  principal will be the original  Class
Certificate  Balance of such class of  Certificates specified in such Prospectus
Supplement, reduced  by  all  distributions  reported to  the  holders  of  such
Certificates  as  allocable  to  principal  and  (i)  in  the  case  of  Accrual
Certificates, unless otherwise specified  in the related Prospectus  Supplement,
increased  by all  interest accrued but  not then distributable  on such Accrual
Certificates and  (ii)  in the  case  of adjustable  rate  Certificates,  unless
otherwise  specified in the related Prospectus Supplement, subject to the effect
of negative amortization.  The related  Prospectus Supplement  will specify  the
method by which the amount of principal to be distributed on the Certificates on
each  Distribution Date will be  calculated and the manner  in which such amount
will be allocated among the classes of Certificates entitled to distributions of
principal.
 
     If so provided in the related Prospectus Supplement, one or more classes of
Senior Certificates  will  be entitled  to  receive all  or  a  disproportionate
percentage  of the  payments of  principal that  are received  from borrowers in
advance of  their  scheduled  due  dates and  are  not  accompanied  by  amounts
representing scheduled interest due after the month of such payments ('Principal
Prepayments')  in the percentages and under the circumstances or for the periods
specified in  such  Prospectus  Supplement. Any  such  allocation  of  Principal
Prepayments  to such class  or classes of  Certificates will have  the effect of
accelerating the amortization of such  Senior Certificates while increasing  the
interests  evidenced  by  the  Subordinated  Certificates  in  the  Trust  Fund.
Increasing the interests of  the Subordinated Certificates  relative to that  of
the  Senior  Certificates  is  intended  to  preserve  the  availability  of the
subordination  provided   by   the  Subordinated   Certificates.   See   'Credit
Enhancement -- Subordination' herein and 'Credit Enhancement -- Subordination of
the Subordinated Certificates' in the related Prospectus Supplement.
 
     Unscheduled   Distributions.    If  specified  in  the  related  Prospectus
Supplement, the Certificates will be subject to receipt of distributions  before
the  next scheduled Distribution Date under  the circumstances and in the manner
described below and in  such Prospectus Supplement.  If applicable, the  Trustee
will  be required to make  such unscheduled distributions on  the day and in the
amount specified in  the related  Prospectus Supplement if,  due to  substantial
payments  of principal (including Principal Prepayments) on the Mortgage Assets,
the Trustee  or the  Master  Servicer determines  that  the funds  available  or
anticipated to be available from the Certificate Account and, if applicable, any
Reserve  Fund,  may  be  insufficient  to  make  required  distributions  on the
Certificates on  such  Distribution  Date. Unless  otherwise  specified  in  the
related  Prospectus Supplement, the amount  of any such unscheduled distribution
that is allocable to principal will  not exceed the amount that would  otherwise
have  been required to  be distributed as  principal on the  Certificates on the
next Distribution Date.  Unless otherwise  specified in  the related  Prospectus
Supplement,   all  unscheduled  distributions  will   include  interest  at  the
applicable  Pass-Through  Rate  (if  any)  on  the  amount  of  the  unscheduled
distribution  allocable to principal for the period and to the date specified in
such Prospectus Supplement.
 
     Unless otherwise  specified  in  the  related  Prospectus  Supplement,  all
distributions  allocable to  principal in  any unscheduled  distribution will be
made in  the same  priority and  manner  as distributions  of principal  on  the
Certificates  would  have been  made  on the  next  Distribution Date,  and with
respect  to  Certificates  of  the  same  class,  unscheduled  distributions  of
principal  will  be  made  on  a  pro  rata  basis.  Notice  of  any unscheduled
distribution  will  be  given  by  the  Trustee  prior  to  the  date  of   such
distribution.
 
ADVANCES
 
     Unless  otherwise 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 Certificate
Account for future distributions to Certificateholders), an amount equal to  the
aggregate  of payments  of principal  and interest  that were  delinquent on the
related Determination Date, subject to the Master Servicer's determination  that
such  advances  will be  recoverable out  of  late payments  by obligors  on the
Mortgage Assets, Liquidation Proceeds, Insurance  Proceeds or otherwise. In  the
case  of Cooperative Loans, the Master Servicer also will be required to advance
any unpaid  maintenance fees  and other  charges under  the related  proprietary
leases as specified in the related Prospectus Supplement.
 
     In making Advances, the Master Servicer will endeavor to maintain a regular
flow  of scheduled interest and principal payments to Certificateholders, rather
than to guarantee or insure against losses.  If Advances are made by the  Master
Servicer from cash being held for future distribution to Certificateholders, the
Master Servicer
 
                                       24
 

<PAGE>
<PAGE>

will  replace such funds on or before any future Distribution Date to the extent
that funds in the applicable Certificate Account on such Distribution Date would
be  less  than  the  amount  required  to  be  available  for  distributions  to
Certificateholders on such date. Any Advances will be reimbursable to the Master
Servicer out of recoveries on the specific Mortgage Assets with respect to which
such  Advances were made (e.g., late payments  made by the related obligors, any
related Insurance Proceeds,  Liquidation Proceeds  or proceeds  of any  Mortgage
Loan  repurchased by the Depositor,  a Sub-Servicer or a  Seller pursuant to the
related Agreement).  In  addition, 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 Certificateholders (including
Senior  Certificateholders) to  the extent  that the  Master Servicer determines
that any  such  Advances  previously  made are  not  ultimately  recoverable  as
described  in the immediately preceding sentence.  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 Mortgagors  on a timely basis. Funds so  advanced
are  reimbursable  to  the  Master  Servicer  to  the  extent  permitted  by the
Agreement. If specified in the related Prospectus Supplement, the obligations of
the Master Servicer to make Advances may be supported by a cash advance  reserve
fund,  a surety  bond or other  arrangement, in  each case as  described in such
Prospectus Supplement.
 
REPORTS TO CERTIFICATEHOLDERS
 
     Prior to or concurrently with each distribution on a Distribution Date  and
except as otherwise set forth in an applicable Prospectus Supplement, the Master
Servicer  or the Trustee will furnish to each Certificateholder of record of the
related Series  a statement  setting forth,  to the  extent applicable  to  such
Series of Certificates, among other things:
 
          (i) the amount of such distribution allocable to principal, separately

          (viii) the related  amount of the  servicing compensation retained  or
     withdrawn  from the  Certificate Account  by the  Master Servicer,  and the
     amount of additional servicing compensation received by the Master Servicer
     attributable to  penalties, fees,  excess  Liquidation Proceeds  and  other
     similar charges and items;
 
          (ix) the number and aggregate principal balances of Mortgage Loans (A)
     delinquent  (exclusive of Mortgage Loans in  foreclosure) (1) 1 to 30 days,

<PAGE>

          (xiv) any amounts remaining under letters of credit, pool policies  or
     other forms of credit enhancement.
 
     Where  applicable, any amount set forth above  may be expressed as a dollar
amount per  single  Certificate of  the  relevant class  having  the  Percentage
Interest   specified  in  the  related  Prospectus  Supplement.  The  report  to
Certificateholders for  any Series  of Certificates  may include  additional  or
other information of a similar nature to that specified above.
 
     In  addition, within  a reasonable  period of  time after  the end  of each
calendar  year,  the  Master  Servicer  or   the  Trustee  will  mail  to   each
Certificateholder  of record at any time during  such calendar year a report (a)
as to  the aggregate  of amounts  reported pursuant  to (i)  and (ii)  for  such
calendar  year or, in  the event such  person was a  Certificateholder of record
during a portion of such calendar year, for the applicable portion of such  year
and (b) such other customary information as may be deemed necessary or desirable
for Certificateholders to prepare their tax returns.
 
CATEGORIES OF CLASSES OF CERTIFICATES
 
     In  general,  classes  of  pass-through  certificates  fall  into different
categories. The following chart identifies and generally defines certain of  the
more  typical categories. The Prospectus Supplement for a series of Certificates
may identify  the  classes  which  comprise such  Series  by  reference  to  the
following categories.

                                                                 PRINCIPAL TYPES
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 Mortgage Assets or other assets of
                                the Trust Fund for the related Series.
Component Certificates........  A class  consisting of  'Components.'  The Components  of  a class  of  Component
                                Certificates may have different principal and/or interest payment characteristics
                                but  together constitute a single  class. Each Component of  a class of Component
                                Certificates may be identified as falling into  one or more of the categories  in
                                this chart.
Notional Amount
  Certificates................  A  class having no principal balance and bearing interest on the related notional
                                amount. The notional amount is used for purposes of the determination of interest
                                distributions.
Planned Principal Class (also
  sometimes referred to as
  'PACs').....................  A class that  is designed  to receive  principal payments  using a  predetermined
                                principal  balance schedule derived by assuming two constant prepayment rates for
                                the underlying  Mortgage  Assets. These  two  rates  are the  endpoints  for  the
                                'structuring  range'  for  the  Planned Principal  Class.  The  Planned Principal
                                Classes in any Series of Certificates may be subdivided into different categories
                                (e.g., Primary Planned Principal Classes, Secondary Planned Principal Classes and
                                so forth) having different effective  structuring ranges and different  principal
                                payment  priorities. The  structuring range  for the  Secondary Planned Principal
                                Class of a  Series of Certificates  will be  narrower than that  for the  Primary
                                Planned Principal Class of such Series.
Scheduled Principal Class.....  A  class that  is designed  to receive  principal payments  using a predetermined
                                principal balance schedule but is not designated as a Planned Principal Class  or
                                Targeted  Principal Class. In many cases, the schedule is derived by assuming two
                                constant prepayment rates for the underlying Mortgage Assets. These two rates are
                                the endpoints for the 'structuring range' for the Scheduled Principal Class.

<S>                             <C>
Sequential Pay................  Classes that receive  principal payments in  a prescribed sequence,  that do  not
                                have  predetermined principal balance schedules  and that under all circumstances
                                receive payments of principal  continuously from the  first Distribution Date  on
                                which they receive principal until they are retired. A single class that receives
                                principal  payments  before or  after all  other  classes in  the same  Series of
                                Certificates may be identified as a Sequential Pay Class.
Strip.........................  A class  that  receives a  constant  proportion,  or 'strip,'  of  the  principal
                                payments on the underlying Mortgage Assets or other assets of the Trust Fund.
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 Mortgage Assets.
 
                                                                 INTEREST TYPES
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 Mortgage Rates borne by the underlying Mortgage Loans).
Interest Only.................  A class that receives some or all of the interest payments made on the underlying
                                Mortgage  Assets or other  assets of the  Trust Fund 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.

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 herein (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:
 
          (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 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 is
due to be 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.
 
     Listed below are historical values of  the Eleventh District Cost of  Funds
Index since January 1989 as reported by the FHLBSF:

- ------------------------------
 
(1)  The  Eleventh District  Cost of Funds  Index reflects  the weighted average
     cost of  funds  of the  members  of the  Eleventh  District for  the  month
     indicated. It is usually announced by the FHLBSF on the last working day of
     the month following the month in which the cost of funds was incurred.
 
     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 Certificates 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 Certificates')  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 Certificates 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
 
                                       29

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  Certificates.
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 for each class of Certificates 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
Certificates.  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 for each class  of Certificates 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 Certificates. 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 CERTIFICATES
 
     If so specified in the related  Prospectus Supplement, one or more  classes
of  the Certificates of any Series  (each, a class of 'Book-Entry Certificates')
may be  initially issued  through the  book-entry facilities  of The  Depository
Trust Company (together with any successor depository selected by the Depositor,
the  'Depository'). Each  class of Book-Entry  Certificates of a  Series will be
issued in  one or  more certificates  which equal  the aggregate  initial  Class
Certificate  Balance (as defined  herein) of each  such class and  which will be
held by a nominee  of the Depository. Unless  otherwise provided in the  related
Prospectus  Supplement, the  following generally  describes the  procedures that
will be applicable to any class of Book-Entry Certificates.
 
     Beneficial interests in  the Book-Entry  Certificates of a  Series will  be
held   indirectly  by  investors  through   the  book-entry  facilities  of  the
Depository, as described herein. Investors may hold such beneficial interests in
the Book-Entry Certificates  in minimum denominations  representing an  original
principal   amount  of  $1,000   and  integral  multiples   in  excess  thereof.
Accordingly, the  Depository or  its nominee  is expected  to be  the holder  of
record  of the  Book-Entry Certificates.  Except as  described below,  no person
acquiring a Book-Entry Certificate (each, a 'beneficial owner') will be entitled
to receive a physical certificate  representing such Certificate (a  'Definitive
Certificate').
 
     The  beneficial  owner's  ownership  of a  Book-Entry  Certificate  will be
recorded on the records of the brokerage firm, bank, thrift institution or other
financial intermediary  (each, a  'Financial Intermediary')  that maintains  the
beneficial   owner's  account   for  such   purpose.  In   turn,  the  Financial
Intermediary's ownership of such Book-Entry Certificate will be recorded on  the
records of the Depository (or of a participating firm that acts as agent for the
Financial  Intermediary, whose interest will in  true be recorded on the records
of the Depository,  if the beneficial  owner's Financial Intermediary  is not  a
Depository  participant).  Therefore,  the  beneficial owner  must  rely  on the
foregoing procedures  to  evidence  its beneficial  ownership  of  a  Book-Entry
Certificate.  Beneficial  ownership  of  a Book-Entry  Certificate  may  only be
transferred by compliance with the  procedures of such Financial  Intermediaries
and Depository participants.
 
     In  accordance with  its normal procedures,  the Depository  is expected to
record the  positions held  by  each Depository  participant in  the  Book-Entry
Certificates,  whether held  for its  own account  or as  a nominee  for another
person. In  general, beneficial  ownership of  Book-Entry Certificates  will  be
subject  to the rules,  regulations and procedures  governing the Depository and
Depository participants as in effect from time to time.
 
     Distributions  on  the  Book-Entry  Certificates  will  be  made  on   each
Distribution  Date  by the  Trustee to  the Depository.  The Depository  will be
responsible for crediting  the amount of  such payments to  the accounts of  the
applicable  Depository participants  in accordance with  the Depository's normal
procedures. Each Depository participant will be responsible for disbursing  such
payments  to  the  beneficial  owners of  the  Book-Entry  Certificates  that it
represents and to each Financial Intermediary  for which it acts as agent.  Each
such  Financial Intermediary  will be  responsible for  disbursing funds  to the
beneficial owners of the Book-Entry Certificates that it represents.
 
     Under a book-entry format, beneficial owners of the Book-Entry Certificates
may experience some delay in their  receipt of payments, since payments will  be
forwarded  by the Trustee to the Depository or  its nominee, as the case may be,
as holder of record of the  Book-Entry Certificates. Because the Depository  can
act  only on  behalf of  Financial Intermediaries,  the ability  of a beneficial
owner to  pledge Book-Entry  Certificates to  persons or  entities that  do  not
participate  in the Depository  system, or otherwise take  actions in respect of
such Book-Entry  Certificates,  may be  limited  due  to the  lack  of  physical
certificates  for  such Book-Entry  Certificates. In  addition, issuance  of the
Book-Entry Certificates  in book-entry  form may  reduce the  liquidity of  such
Certificates  in the secondary  market since certain  potential investors may be
unwilling to  purchase  Certificates  for  which  they  cannot  obtain  physical
certificates.
 
     Unless and until Definitive Certificates are issued, it is anticipated that
the  only  'Certificateholder'  of  the  Book-Entry  Certificates  will  be  the
Depository or its nominee. Beneficial owners of the Book-Entry Certificates will
not be Certificateholders, as that term  will be used in the Agreement  relating
to such series of Certificates. Beneficial owners are only permitted to exercise
the rights of Certificateholders indirectly through Financial Intermediaries and
the Depository. Monthly and annual reports on the related Trust Fund provided to
the  Depository or its nominee, as  the case may be, as  holder of record of the
Book-Entry Certificates,  may  be  made  available  to  beneficial  owners  upon
request,  in accordance with the rules,  regulations and procedures creating and
affecting  the  Depository,  and  to  the  Financial  Intermediaries  to   whose
Depository  accounts the Book-Entry  Certificates of such  beneficial owners are
credited.

     Unless otherwise specified in the related Prospectus Supplement, unless and
until Definitive Certificates are  issued, the Depository  will take any  action
permitted  to  be taken  by  the holders  of  the Book-Entry  Certificates  of a
particular Series under the  related Agreement only at  the direction of one  or
more  Financial  Intermediaries  to whose  Depository  accounts  such Book-Entry
Certificates are credit to the extent that  such actions are taken on behalf  of
Financial Intermediaries whose holdings include such Book-Entry Certificates.
 
     Unless otherwise specified in the related Prospectus Supplement, Definitive
Certificates  will be issued to beneficial owners of Book-Entry Certificates, or
their nominees, rather than to the Depository, only if (a) the Depository or the
Depositor advises  the Trustee  in  writing that  the  Depository is  no  longer
willing, qualified or able to discharge properly its responsibilities as nominee
and  depository with respect to the Book-Entry Certificates and the 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 the  Depository;
or  (c)  after the  occurrence  of an  Event  of Default,  beneficial  owners of
Certificates  representing  not  less  than  51%  of  the  aggregate  Percentage
Interests  evidenced by each class of  Certificates of the related Series issued
as Book-Entry Certificates  advise the  Trustee and the  Depository through  the
Financial Intermediaries in writing that the continuation of a book-entry system
through  the  Depository (or  a  successor thereto)  is  no longer  in  the best
interests of the beneficial owners.
 
     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  of  Definitive
Certificates.  Upon surrender  by the  Depository of  the global  certificate or
certificates representing  the  Book-Entry  Certificates  and  instructions  for
re-registration,  the  Trustee  will  issue  the  Definitive  Certificates,  and
thereafter  the  Trustee   will  recognize  the   holders  of  such   Definitive
Certificates  as Certificateholders under the  Agreement relating to such Series
of Certificates.
 
                               CREDIT ENHANCEMENT
 
GENERAL
 
     Credit enhancement may be provided with respect to one or more classes of a
Series of Certificates  or with respect  to the Mortgage  Assets in the  related
Trust  Fund.  Credit enhancement  may  be in  the  form of  a  limited financial
guaranty policy issued by an entity named in the related Prospectus  Supplement,
the subordination of one or more classes of the Certificates of such Series, the
establishment  of one or more reserve funds, the use of a cross-support feature,
use of  a  mortgage  pool  insurance policy,  bankruptcy  bond,  special  hazard
insurance  policy, surety bond, letter of credit, guaranteed investment contract
or other  method  of credit  enhancement  described in  the  related  Prospectus
Supplement,  or any combination of the  foregoing. Unless otherwise specified in
the related Prospectus Supplement, no credit enhancement will provide protection
against all risks of loss or guarantee repayment of the entire principal balance
of the  Certificates and  interest thereon.  If losses  occur which  exceed  the
amount  covered by  credit enhancement  or which are  not covered  by the credit
enhancement,  Certificateholders  will  bear   their  allocable  share  of   any
deficiencies.
 
SUBORDINATION
 
     If so specified in the related Prospectus Supplement, the rights of holders
of   one  or  more  classes  of  Subordinated  Certificates  (the  'Subordinated
Certificateholders') will be subordinate to the rights of holders of one or more
other classes of Senior Certificates  (the 'Senior Certificateholders') of  such
Series   to  distributions   in  respect   of  scheduled   principal,  Principal
Prepayments, interest or any combination thereof that otherwise would have  been
payable  to holders of Subordinated Certificates  under the circumstances and to
the extent specified in the related  Prospectus Supplement. If specified in  the
related  Prospectus Supplement, delays  in receipt of  scheduled payments on the
Mortgage Assets and  losses with respect  to the Mortgage  Assets will be  borne
first  by the various classes of Subordinated Certificates and thereafter by the
various classes of Senior Certificates, in each case under the circumstances and
subject to the limitations specified in such related Prospectus Supplement.  The
aggregate distributions in respect of delinquent payments on the Mortgage Assets
over  the lives  of the  Certificates or  at any  time, the  aggregate losses in
respect of Mortgage Assets which must be borne by the Subordinated  Certificates
by  virtue  of  subordination  and the  amount  of  the  distributions otherwise
distributable to the Subordinated Certificateholders that will be  distributable
to  Senior  Certificateholders  on  any  Distribution  Date  may  be  limited as
specified in the  related Prospectus Supplement.  If aggregate distributions  in
respect  of delinquent  payments on the  Mortgage Assets or  aggregate losses in
respect of such
 
                                       32
 

<PAGE>
<PAGE>

Mortgage Assets were to  exceed the amount specified  in the related  Prospectus
Supplement,   Senior   Certificateholders   would  experience   losses   on  the
Certificates.
 
     If specified  in  the related  Prospectus  Supplement, various  classes  of
Senior  Certificates and Subordinated Certificates may themselves be subordinate
in their right to receive certain  distributions to other classes of Senior  and
Subordinated  Certificates, respectively,  through a cross  support mechanism or
otherwise.
 
     As between  classes  of  Senior  Certificates and  as  between  classes  of
Subordinated Certificates, distributions may be allocated among such classes (i)
in  the order  of their scheduled  final distribution dates,  (ii) in accordance
with a schedule or  formula, (iii) in  relation to the  occurrence of events  or
(iv)  otherwise, in each case as specified in the related Prospectus Supplement.
As  between   classes  of   Subordinated   Certificates,  payments   to   Senior
Certificateholders  on account  of delinquencies or  losses and  payments to the
Reserve  Fund  will  be  allocated  as  specified  in  the  related   Prospectus
Supplement.
 
MORTGAGE POOL INSURANCE POLICIES
 
     If  specified in the  related Prospectus Supplement  relating to a Mortgage
Pool, a  separate  mortgage  pool insurance  policy  ('Mortgage  Pool  Insurance
Policy')  will be obtained for the Mortgage  Pool and issued by the insurer (the
'Pool  Insurer')  named  in  such  Prospectus  Supplement.  Each  Mortgage  Pool
Insurance Policy will, subject to the limitations described below, cover loss by
reason of default in payment on Mortgage Loans in the Mortgage Pool in an amount
equal  to a percentage specified in  such Prospectus Supplement of the aggregate
principal balance  of such  Mortgage Loans  on the  Cut-off Date  which are  not
covered  as to their  entire outstanding principal  balances by Primary Mortgage
Insurance Policies.  As more  fully described  below, the  Master Servicer  will
present  claims thereunder to the Pool Insurer  on behalf of itself, the Trustee
and the Certificateholders. The Mortgage  Pool Insurance Policies, however,  are
not  blanket policies  against loss,  since claims  thereunder may  be made only
respecting particular defaulted  Mortgage Loans  and only  upon satisfaction  of
certain  conditions precedent described below. Unless otherwise specified in the
related Prospectus Supplement,  the Mortgage  Pool Insurance  Policies will  not
cover  losses due  to a  failure to  pay or  denial of  a claim  under a Primary
Mortgage Insurance Policy.
 
     Unless otherwise  specified  in  the related  Prospectus  Supplement,  each
Mortgage  Pool  Insurance Policy  will  provide that  no  claims may  be validly
presented unless (i) any required Primary Mortgage Insurance Policy is in effect
for the defaulted Mortgage  Loan and a claim  thereunder has been submitted  and
settled;  (ii) hazard insurance on the  related Mortgaged Property has been kept
in force and real  estate taxes and other  protection and preservation  expenses
have been paid; (iii) if there has been physical loss or damage to the Mortgaged
Property,  it has been  restored to its physical  condition (reasonable wear and
tear excepted) at the time of issuance  of the policy; and (iv) the insured  has
acquired good and merchantable title to the Mortgaged Property free and clear of
liens   except  certain  permitted  encumbrances.  Upon  satisfaction  of  these
conditions, the Pool  Insurer will have  the option either  (a) to purchase  the
Mortgaged  Property at  a price  equal to the  principal balance  of the related
Mortgage Loan plus accrued and unpaid interest at the Mortgage Rate to the  date
of  such purchase and certain expenses incurred by the Master Servicer on behalf
of the Trustee and Certificateholders or (b) to pay the amount by which the  sum
of  the principal balance of the defaulted Mortgage Loan plus accrued and unpaid
interest at  the Mortgage  Rate to  the date  of payment  of the  claim and  the
aforementioned  expenses exceeds the proceeds received  from an approved sale of
the Mortgaged Property, in either case net of certain amounts paid or assumed to
have been  paid under  the related  Primary Mortgage  Insurance Policy.  If  any
Mortgaged  Property is  damaged, and proceeds,  if any, from  the related hazard
insurance  policy  or  the  applicable  Special  Hazard  Insurance  Policy   are
insufficient to restore the damaged property to a condition sufficient to permit
recovery  under the Mortgage Pool Insurance Policy, the Master Servicer will not
be required to expend its  own funds to restore  the damaged property unless  it
determines   that   (i)  such   restoration  will   increase  the   proceeds  to
Certificateholders on liquidation  of the Mortgage  Loan after reimbursement  of
the  Master Servicer for its expenses and (ii) such expenses will be recoverable
by it through proceeds of the sale of the Mortgaged Property or proceeds of  the
related Mortgage Pool Insurance Policy or any related Primary Mortgage Insurance
Policy.
 
     Unless  otherwise  specified  in  the  related  Prospectus  Supplement,  no
Mortgage Pool Insurance Policy will insure (and many Primary Mortgage  Insurance
Policies  do not insure) against  loss sustained by reason  of a default arising
from, among  other  things,  (i)  fraud or  negligence  in  the  origination  or
servicing  of a Mortgage Loan, including misrepresentation by the Mortgagor, the
originator or persons involved  in the origination thereof,  or (ii) failure  to
construct  a Mortgaged Property  in accordance with  plans and specifications. A
failure of coverage attributable to one of the foregoing events might result  in
a breach of the related Seller's
 
                                       33
 

<PAGE>
<PAGE>

representations  described  above and,  in  such event,  might  give rise  to an
obligation on the part of such Seller to repurchase the defaulted Mortgage  Loan
if  the breach cannot be cured by such Seller. No Mortgage Pool Insurance Policy
will cover (and many Primary Mortgage  Insurance Policies do not cover) a  claim
in  respect of  a defaulted  Mortgage Loan occurring  when the  servicer of such
Mortgage Loan, at the  time of default  or thereafter, was  not approved by  the
applicable insurer.
 
     Unless  otherwise  specified  in  the  related  Prospectus  Supplement, the
original amount of coverage  under each Mortgage Pool  Insurance Policy will  be
reduced over the life of the related Certificates by the aggregate dollar amount
of  claims  paid less  the aggregate  of the  net amounts  realized by  the Pool
Insurer upon disposition of all foreclosed properties. The amount of claims paid
will include certain expenses incurred by the Master Servicer as well as accrued
interest on  delinquent Mortgage  Loans to  the date  of payment  of the  claim,
unless otherwise specified in the related Prospectus Supplement. Accordingly, if
aggregate  net claims  paid under any  Mortgage Pool Insurance  Policy reach the
original policy limit, coverage under  that Mortgage Pool Insurance Policy  will
be exhausted and any further losses will be borne by the Certificateholders.
 
SPECIAL HAZARD INSURANCE POLICIES
 
     If  specified  in the  related  Prospectus Supplement,  a  separate Special
Hazard Insurance  Policy will  be obtained  for the  Mortgage Pool  and will  be
issued  by the insurer  (the 'Special Hazard Insurer')  named in such Prospectus
Supplement. Each Special  Hazard Insurance Policy  will, subject to  limitations
described  below, protect holders  of the related Certificates  from (i) loss by
reason of damage to  Mortgaged Properties caused  by certain hazards  (including
earthquakes and, to a limited extent, tidal waves and related water damage or as
otherwise  specified in the  related Prospectus Supplement)  not insured against
under the standard form of hazard insurance policy for the respective states  in
which  the Mortgaged Properties are located or under a flood insurance policy if
the Mortgaged Property is located in a federally designated flood area and  (ii)
loss  caused by reason of the application of the coinsurance clause contained in
hazard insurance policies. See  'The Pooling and  Servicing Agreement --  Hazard
Insurance'.  No Special Hazard Insurance Policy  will cover losses occasioned by
fraud or conversion by the Trustee or Master Servicer, war, insurrection,  civil
war,  certain  governmental  action,  errors in  design,  faulty  workmanship or
materials (except under  certain circumstances), nuclear  or chemical  reaction,
flood  (if the  Mortgaged Property  is located  in a  federally designated flood
area), nuclear or chemical contamination and certain other risks. The amount  of
coverage  under any  Special Hazard  Insurance Policy  will be  specified in the
related Prospectus Supplement. Each Special Hazard Insurance Policy will provide
that no claim may be paid unless  hazard and, if applicable, flood insurance  on
the  property  securing the  Mortgage Loan  have  been kept  in force  and other
protection and preservation expenses have been paid.
 
     Subject to the foregoing limitations, and unless otherwise specified in the
related Prospectus Supplement, each Special Hazard Insurance Policy will provide
that where there has been damage to property securing a foreclosed Mortgage Loan
(title to which has been acquired by the insured) and to the extent such  damage
is not covered by the hazard insurance policy or flood insurance policy, if any,
maintained  by the Mortgagor or the  Master Servicer, the Special Hazard Insurer
will pay the lesser of (i) the cost of repair or replacement of such property or
(ii) upon transfer  of the property  to the Special  Hazard Insurer, the  unpaid
principal  balance of  such Mortgage  Loan at  the time  of acquisition  of such
property by foreclosure or deed in lieu of foreclosure, plus accrued interest to
the date  of  claim settlement  and  certain  expenses incurred  by  the  Master
Servicer  with respect to  such property. If  the unpaid principal  balance of a
Mortgage Loan plus accrued interest and certain expenses is paid by the  Special
Hazard  Insurer, the amount of further coverage under the related Special Hazard
Insurance Policy will be reduced by such  amount less any net proceeds from  the
sale  of the property.  Any amount paid as  the cost of  repair of such property
will further  reduce  coverage  by such  amount.  So  long as  a  Mortgage  Pool
Insurance Policy remains in effect, the payment by the Special Hazard Insurer of
the  cost of repair or  of the unpaid principal  balance of the related Mortgage
Loan plus  accrued interest  and  certain expenses  will  not affect  the  total
insurance  proceeds  paid to  Certificateholders, but  will affect  the relative
amounts of coverage remaining under the related Special Hazard Insurance  Policy
and Mortgage Pool Insurance Policy.
 
     To  the extent specified in the  Prospectus Supplement, the Master Servicer
may deposit  cash, an  irrevocable  letter of  credit  or any  other  instrument
acceptable  to each nationally recognized  rating agency rating the Certificates
of the related Series in a special  trust account to provide protection in  lieu
of  or in addition  to that provided  by a Special  Hazard Insurance Policy. The
amount of any Special Hazard Insurance Policy  or of the deposit to the  special
trust  account in lieu thereof  relating to such Certificates  may be reduced so
long as any such  reduction will not  result in a downgrading  of the rating  of
such Certificates by any such rating agency.

BANKRUPTCY BONDS
 
     If  specified in the related Prospectus  Supplement, a bankruptcy bond (the
'Bankruptcy Bond') to cover losses resulting from proceedings under the  federal
Bankruptcy  Code with respect  to a Mortgage  Loan will be  issued by an insurer
named in such  Prospectus Supplement. Each  Bankruptcy Bond will  cover, to  the
extent  specified in the related Prospectus Supplement, certain losses resulting
from a reduction by  a bankruptcy court of  scheduled payments of principal  and
interest on a Mortgage Loan or a reduction by such court of the principal amount
of  a Mortgage Loan and will cover certain unpaid interest on the amount of such
a principal reduction from the date of the filing of a bankruptcy petition.  The
required  amount of coverage under each Bankruptcy Bond will be set forth in the
related Prospectus Supplement. Coverage under a Bankruptcy Bond may be cancelled
or reduced by the  Master Servicer if such  cancellation or reduction would  not
adversely affect the then current rating or ratings of the related Certificates.
See  'Certain Legal Aspects of the Mortgage Loans -- Anti-Deficiency Legislation
and Other Limitations on Lenders' herein.
 
     To the extent specified in  the Prospectus Supplement, the Master  Servicer
may  deposit  cash, an  irrevocable  letter of  credit  or any  other instrument
acceptable to each nationally recognized  rating agency rating the  Certificates
of  the related Series in a special  trust account to provide protection in lieu
of or in  addition to  that provided  by a Bankruptcy  Bond. The  amount of  any
Bankruptcy  Bond or of the deposit to  the special trust account in lieu thereof
relating to such Certificates may be reduced so long as any such reduction  will
not  result in  a downgrading  of the  rating of  such Certificates  by any such
rating agency.
 
RESERVE FUND
 
     If so specified in the  related Prospectus Supplement, credit support  with
respect  to a Series  of Certificates may  be provided by  the establishment and
maintenance with the Trustee for such  Series of Certificates, in trust, of  one
or  more  reserve  funds  (the  'Reserve Fund')  for  such  Series.  The related
Prospectus Supplement  will  specify whether  or  not  a Reserve  Fund  will  be
included in the Trust Fund for such Series.
 
     The  Reserve Fund for a Series will be funded (i) by the deposit therein of
cash, U.S. Treasury securities or instruments evidencing ownership of  principal
or  interest payments thereon, letters of  credit, demand notes, certificates of
deposit or  a combination  thereof  in the  aggregate  amount specified  in  the
related  Prospectus Supplement, (ii) by the deposit therein from time to time of
certain amounts, as specified in the related Prospectus Supplement, to which the
Subordinated Certificateholders, if any, would otherwise be entitled or (iii) in
such other manner as may be specified in the related Prospectus Supplement.
 
     Any amounts on deposit in  the Reserve Fund and  the proceeds of any  other
instrument  deposited therein  upon maturity  will be  held in  cash or  will be
invested in 'Permitted  Investments' which,  unless otherwise  specified in  the
related Prospectus Supplement, will include obligations of the United States and
certain  agencies thereof,  certificates of  deposit, certain  commercial paper,
time deposits  and bankers  acceptances sold  by eligible  commercial banks  and
certain  repurchase  agreements  of  United  States  government  securities with
eligible commercial banks. If a letter of credit is deposited with the  Trustee,
such  letter of  credit will be  irrevocable. Unless otherwise  specified in the
related Prospectus Supplement,  any instrument deposited  therein will name  the
Trustee,  in its capacity as trustee  for the Certificateholders, as beneficiary
and will be issued by an entity acceptable to each rating agency that rates  the
Certificates.  Additional information with respect to such instruments deposited
in the Reserve Funds will be set forth in the related Prospectus Supplement.
 
     Any amounts so deposited and payments  on instruments so deposited will  be
available  for  withdrawal  from  the  Reserve  Fund  for  distribution  to  the
Certificateholders for the purposes, in the manner and at the times specified in
the related Prospectus Supplement.
 
CROSS SUPPORT
 
     If specified in the related Prospectus Supplement, the beneficial ownership
of separate  groups of  assets included  in a  Trust Fund  may be  evidenced  by
separate  classes of  the related Series  of Certificates. In  such case, credit
support may  be  provided  by  a  cross  support  feature  which  requires  that
distributions  be  made with  respect  to Certificates  evidencing  a beneficial
ownership interest in other asset groups within the same Trust Fund. The related
Prospectus Supplement for a  Series that includes a  cross support feature  will
describe the manner and conditions for applying such cross support feature.
 
     If specified in the related Prospectus Supplement, the coverage provided by
one  or  more forms  of credit  support may  apply concurrently  to two  or more
related Trust Funds. If applicable, the related Prospectus
 
                                       35
 

<PAGE>
<PAGE>

Supplement will identify the  Trust Funds to which  such credit support  relates
and the manner of determining the amount of the coverage provided thereby and of
the application of such coverage to the identified Trust Funds.
 
OTHER INSURANCE, SURETY BONDS, GUARANTIES, LETTERS OF CREDIT AND SIMILAR
INSTRUMENTS OR AGREEMENTS
 
     If  specified in the  related Prospectus Supplement, a  Trust Fund may also
include insurance,  guaranties,  surety  bonds, letters  of  credit  or  similar
arrangements  for the  purpose of (i)  maintaining timely  payments or providing
additional protection against losses on the assets included in such 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
Certificateholders are entitled to receive amounts deposited in various accounts
held by the Trustee upon the terms specified in such Prospectus Supplement.
 
                      YIELD AND PREPAYMENT CONSIDERATIONS
 
     The yields to maturity and weighted average lives of the Certificates  will
be affected primarily by the amount and timing of principal payments received on
or  in respect of  the Mortgage Assets  included in the  related Trust Fund. The
original terms to maturity of the underlying mortgage loans with respect to  the
Mortgage  Assets in a given  Mortgage Pool will vary  depending upon the type of
mortgage loans included  therein, and  each Prospectus  Supplement will  contain
information  with respect  to the  type and  maturities of  such mortgage loans.
Unless otherwise specified  in the related  Prospectus Supplement, the  mortgage
loans  may  be prepaid  without penalty  in full  or  in part  at any  time. The
prepayment experience  on the  underlying  mortgage loans  with respect  to  the
Mortgage Assets will affect the life of the related Series of Certificates.
 
     A number of factors, including homeowner mobility, economic conditions, the
presence  and enforceability  of due-on-sale  clauses, mortgage  market interest
rates and  the  availability  of  mortgage  funds,  may  affect  the  prepayment
experience of mortgage loans.
 
     Unless  otherwise  provided  in  the  related  Prospectus  Supplement,  all
conventional Mortgage Loans will  contain due-on-sale provisions permitting  the
mortgagee  to accelerate the maturity of the loan upon sale or certain transfers
by the Mortgagor of the underlying Mortgaged Property. Mortgage Loans insured by
the FHA and Mortgage Loans partially guaranteed by the VA are assumable with the
consent of the FHA and  the VA, respectively. Thus,  the rate of prepayments  on
such  Mortgage  Loans may  be  lower than  that  on conventional  Mortgage Loans
bearing comparable  interest rates.  Unless otherwise  provided in  the  related
Prospectus   Supplement,  the   Master  Servicer  generally   will  enforce  any
due-on-sale or due-on-encumbrance clause, to the extent it has knowledge of  the
conveyance or further encumbrance or the proposed conveyance or proposed further
encumbrance  of  the  Mortgaged  Property and  reasonably  believes  that  it is
entitled to  do so  under applicable  law; provided,  however, 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 Pooling  and
Servicing Agreement  -- Collection Procedures' and 'Certain Legal Aspects of the
Mortgage Loans' herein for a description of certain provisions of each Agreement
and  certain legal developments that may affect the prepayment experience on the
Mortgage Loans.
 
     The rate of  prepayments with  respect to conventional  mortgage loans  has
fluctuated  significantly in recent years. In  general, if prevailing rates fall
significantly below the Mortgage Rates borne by the Mortgage Loans, the Mortgage
Loans are likely  to be subject  to higher prepayment  rates than if  prevailing
interest rates remain at or above such Mortgage Rates. Conversely, if prevailing
interest  rates rise appreciably above the  Mortgage Rates borne by the Mortgage
Loans, the Mortgage Loans are likely to experience a lower prepayment rate  than
if  prevailing rates remain at or below  such Mortgage Rates. However, there can
be no assurance that such will be the case.
 
     When a full prepayment is made on a Mortgage Loan, the Mortgagor is charged
interest on the principal amount  of the Mortgage Loan  so prepaid only for  the
number  of days in the  month actually elapsed up to  the date of the prepayment
rather than  for  a  full  month. Unless  otherwise  specified  in  the  related
Prospectus  Supplement, the effect of prepayments in  full will be to reduce the
amount of interest passed through  in the following month to  Certificateholders
because interest on the principal amount of any Mortgage Loan so prepaid will be
paid only to the date of prepayment. Partial prepayments in a given month may be
applied  to the outstanding principal balances  of the Mortgage Loans so prepaid
on the first day of the month of receipt or the month following receipt. In  the
latter  case, partial prepayments will not  reduce the amount of interest passed
 
                                       36
 

<PAGE>
<PAGE>

through in  such month.  Unless otherwise  specified in  the related  Prospectus
Supplement,  both full and partial prepayments  will not be passed through until
the month following receipt.
 
     The effective yield to Certificateholders  will be slightly lower than  the
yield  otherwise produced by the applicable Pass-Through Rate and purchase price
because while interest will accrue on each  Mortgage Loan from the first day  of
the  month (unless otherwise provided in the related Prospectus Supplement), the
distribution of such interest will not be made earlier than the month  following
the month of accrual.
 
     Under  certain circumstances,  the Master  Servicer or  the holders  of the
residual interests in a REMIC  may have the option to  purchase the assets of  a
Trust  Fund  thereby  effecting  earlier retirement  of  the  related  Series of
Certificates. See 'The Pooling and Servicing Agreement -- Termination;  Optional
Termination' herein.
 
     Factors  other than those  identified herein and  in the related Prospectus
Supplement could significantly affect principal prepayments at any time and over
the lives of the Certificates. The relative contribution of the various  factors
affecting  prepayment may also vary from time to time. There can be no assurance
as to the rate  of payment of principal  of the Mortgage Assets  at any time  or
over the lives of the Certificates.
 
     The Prospectus Supplement relating to a Series of Certificates will discuss
in  greater  detail the  effect of  the  rate and  timing of  principal payments
(including Principal  Prepayments),  delinquencies  and  losses  on  the  yield,
weighted average lives and maturities of such Certificates.

                      THE POOLING AND SERVICING AGREEMENT
 
     Set  forth below is a summary of  certain provisions of the Agreement which
are not described elsewhere in  this Prospectus. Where particular provisions  or
terms  used in the  Agreement are referred  to, such provisions  or terms are as
specified in the related Agreement.
 
ASSIGNMENT OF MORTGAGE ASSETS
 
     Assignment of  the  Mortgage  Loans.    At the  time  of  issuance  of  the
Certificates of a Series, the Depositor will cause the Mortgage Loans comprising
the  related  Trust  Fund to  be  assigned  to the  Trustee,  together  with all
principal and interest  received by or  on behalf  of the Depositor  on or  with
respect  to such Mortgage Loans after the Cut-off Date, other than principal and
interest due on or before the Cut-off Date and other than any Retained  Interest
specified  in the related Prospectus  Supplement. The Trustee will, concurrently
with such assignment, deliver the Certificates to the Depositor in exchange  for
the  Mortgage  Loans.  Each  Mortgage  Loan will  be  identified  in  a schedule
appearing as an  exhibit to the  related Agreement. Such  schedule will  include
information  as to the outstanding principal balance of each Mortgage Loan after
application of  payments  due  on  the Cut-off  Date,  as  well  as  information
regarding  the Mortgage Rate, the current scheduled monthly payment of principal
and interest, the maturity of the  loan, the Loan-to-Value Ratio at  origination
and certain other information.
 
     In  addition, the Depositor  will deliver or  cause to be  delivered to the
Trustee (or to the custodian hereinafter referred to) as to each Mortgage  Loan,
among  other things, (i) the Mortgage Note endorsed without recourse in blank or
to the  order of  the  Trustee, (ii)  the mortgage,  deed  of trust  or  similar
instrument (the 'Mortgage') with evidence of recording indicated thereon (except
for  any Mortgage not returned  from the public recording  office, in which case
the Depositor  will,  unless  otherwise  specified  in  the  related  Prospectus
Supplement,  deliver or cause to  be delivered a copy  of such Mortgage together
with a certificate  that the  original of such  Mortgage was  delivered to  such
recording  office), (iii)  an assignment of  the Mortgage to  the Trustee, which
assignment will be in recordable form and (iv) such other security documents  as
may  be specified in the related Prospectus Supplement or the related Agreement.
Unless otherwise specified in the  related Prospectus Supplement, the  Depositor
will  promptly cause the assignments of the  related loans to be recorded in the
appropriate public office for real property records, except in states in  which,
in  the opinion  of counsel  acceptable to  the Trustee,  such recording  is not
required to protect the  Trustee's interest in such  loans against the claim  of
any  subsequent transferee or any  successor to or creditor  of the Depositor or
the originator of such loans.
 
     With respect  to  any  Mortgage  Loans  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.
 
     The Trustee (or  the custodian  hereinafter referred to)  will review  such
Mortgage  Loan  documents  within  the  time  period  specified  in  the related
Prospectus Supplement  after receipt  thereof, and  the Trustee  will hold  such
documents  in trust for the benefit  of the Certificateholders. Unless otherwise
specified in the related Prospectus Supplement, if any such document is found to
be missing or defective in any material respect, the Trustee (or such custodian)
will notify the Master Servicer and the Depositor, and the Master Servicer  will
notify  the related  Seller. If  the Seller cannot  cure the  omission or defect
within the  time period  specified in  the related  Prospectus Supplement  after
receipt  of such notice,  the Seller will  be obligated to  purchase the related
Mortgage Loan from the Trustee at the Purchase Price or, if so specified in  the
related  Prospectus Supplement, replace such Mortgage Loan with another mortgage
loan that  meets  certain  requirements  set forth  therein.  There  can  be  no
assurance  that a  Seller will  fulfill this  purchase obligation.  Although the
Master Servicer  may be  obligated  to enforce  such  obligation to  the  extent
described  above  under 'Mortgage  Loan Program  -- Representations  by Sellers;
Repurchases,' neither the Master Servicer nor the Depositor will be obligated to
purchase such Mortgage Loan if the  Seller defaults on its purchase  obligation,
unless  such  breach  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  purchase
obligation constitutes the  sole remedy available  to the Certificateholders  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 Mortgage Loans as agent of the Trustee.

     Notwithstanding  the foregoing provisions, with respect to a Trust Fund for
which a REMIC election is to  be made, unless the related Prospectus  Supplement
otherwise provides, no purchase of a Mortgage Loan will be made if such purchase
would result in a prohibited transaction tax under the Code.
 
     Assignment  of  Agency Securities.   The  Depositor  will cause  the Agency
Securities to be registered in the name  of the Trustee or its nominee, and  the
Trustee  concurrently will  execute, countersign  and deliver  the Certificates.
Each Agency Security will be identified in a schedule appearing as an exhibit to
the Agreement,  which will  specify  as to  each  Agency Security  the  original
principal  amount and outstanding principal balance  as of the Cut-off Date, the
annual pass-through rate (if any) and the maturity date.
 
     Assignment of Private Mortgage-Backed Securities.  The Depositor will cause
the Private  Mortgage-Backed Securities  to be  registered in  the name  of  the
Trustee. The Trustee (or the custodian) will have possession of any certificated
Private  Mortgage-Backed Securities.  Unless otherwise specified  in the related
Prospectus Supplement, the Trustee will not  be in possession of or be  assignee
of  record of any underlying assets  for a Private Mortgage-Backed Security. See
'The Trust  Fund --  Private Mortgage-Backed  Securities' herein.  Each  Private
Mortgage-Backed  Security  will  be identified  in  a schedule  appearing  as an
exhibit to  the related  Agreement  which will  specify the  original  principal
amount,   outstanding  principal  balance   as  of  the   Cut-off  Date,  annual
pass-through rate or interest rate and maturity date and certain other pertinent
information for each Private Mortgage-Backed Security conveyed to the Trustee.
 
PAYMENTS ON MORTGAGE ASSETS; DEPOSITS TO CERTIFICATE ACCOUNT
 
     The Master Servicer will establish and maintain or cause to be  established
and  maintained with  respect to  the related Trust  Fund a  separate account or
accounts for the collection  of payments on the  related Mortgage Assets in  the
Trust  Fund (the 'Certificate Account'), which unless otherwise specified in the
related Prospectus Supplement, must be  either (i) maintained with a  depository
institution  the  short-term debt  obligations of  which  (or in  the case  of a
depository institution that is  the principal subsidiary  of a holding  company,
the  short-term debt obligations  of which) are rated  in the highest short-term
rating category by the nationally recognized statistical rating  organization(s)
that  rated one or more  classes of the related  Series of Certificates (each, a
'Rating Agency'), (ii) an  account or accounts the  deposits in which are  fully
insured  by either the BIF or SAIF, (iii) an account or accounts the deposits in
which are insured by the BIF or SAIF to the limits established by the FDIC,  and
the uninsured deposits in which are otherwise secured such that, as evidenced by
an  opinion of counsel, the Certificateholders have  a claim with respect to the
funds in the Certificate 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  Certificate  Account  is  maintained,  (iv)  a  trust  account  or accounts
maintained with  the  trust  department  of  a  federal  or  a  state  chartered
depository  institution or trust company, acting  in a fiduciary capacity or (v)
an  account  or  accounts  otherwise  acceptable  to  each  Rating  Agency.  The
collateral  eligible to secure amounts in  the Certificate Account is limited to
Permitted Investments. A Certificate  Account may be  maintained as an  interest
bearing  account  or  the  funds  held  therein  may  be  invested  pending each
succeeding  Distribution  Date  in   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  Certificate  Account  as  additional  compensation  and  will  be
obligated  to  deposit  in  the  Certificate  Account  the  amount  of  any loss
immediately as  realized. The  Certificate Account  may be  maintained with  the
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
Certificate  Account  for  each Trust  Fund  on  a daily  basis,  to  the extent
applicable and unless otherwise specified  in the related Prospectus  Supplement
and  provided in the Agreement, the  following payments and collections received
or Advances made by  or on behalf  of it subsequent to  the Cut-off Date  (other
than  payments due on  or before the  Cut-off Date and  exclusive of any amounts
representing Retained Interest):
 
          (i)  all  payments  on  account  of  principal,  including   Principal
     Prepayments  and,  if  specified  in  the  related  Prospectus  Supplement,
     prepayment penalties, on the Mortgage Loans;
 
          (ii) all payments on account of interest on the Mortgage Loans, net of
     applicable servicing compensation;
 
          (iii) 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
 
                                       39

     of  unreimbursed  expenses  incurred  in  connection  with  liquidation  or
     foreclosure ('Liquidation  Expenses') and  unreimbursed Advances,  if  any)
     received  and  retained in  connection  with the  liquidation  of defaulted
     Mortgage 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 Certificateholders by  foreclosure
     or deed in lieu of foreclosure;
 
          (iv)  all proceeds of any Mortgage Loan or property in respect thereof
     purchased by the Master Servicer, the Depositor or any Seller as  described
     under 'Mortgage Loan Program -- Representations by Sellers; Repurchases' or
     'The  Pooling  and Servicing  Agreement --  Assignment of  Mortgage Assets'
     above and all proceeds of any Mortgage Loan repurchased as described  under
     'The  Pooling and Servicing Agreement -- Termination; Optional Termination'
     below;
 
          (v) all payments required to  be deposited in the Certificate  Account
     with  respect  to any  deductible clause  in  any blanket  insurance policy
     described under ' -- Hazard Insurance' 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 Certificate 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 Certificate
     Account pursuant to the Agreement.
 
     The Master Servicer (or the Depositor, as applicable) may from time to time
direct the institution that maintains the Certificate Account to withdraw  funds
from the Certificate Account for the following purposes:
 
          (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  Certificate
     Account credited thereto;
 
          (ii)  to reimburse  the Master  Servicer for  Advances, such  right of
     reimbursement with respect to  any Mortgage Loan  being limited to  amounts
     received  that represent  late recoveries  of payments  of principal and/or
     interest on  such  Mortgage  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 Mortgage Loan
     or property acquired  in respect  thereof that  has been  purchased by  the
     Master Servicer pursuant to the Agreement, all amounts received thereon and
     not  taken  into  account  in determining  the  principal  balance  of such
     repurchased Mortgage Loan;
 
          (vii) to reimburse the Master  Servicer or the Depositor for  expenses
     incurred and reimbursable pursuant to the Agreement;
 
          (viii) to withdraw any amount deposited in the Certificate Account and
     not required to be deposited therein; and
 
          (ix)  to clear and terminate  the Certificate 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  Certificate
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 Certificates.
 
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 Mortgage
Loans and will, consistent with each  Agreement and any Mortgage Pool  Insurance
Policy,  Primary  Mortgage  Insurance  Policy, FHA  Insurance,  VA  Guaranty and
Bankruptcy Bond or alternative  arrangements, follow such collection  procedures
as  are customary  with respect  to mortgage  loans that  are comparable  to the
Mortgage Loans.  Consistent with  the above,  the Master  Servicer may,  in  its
 
                                       40
 

<PAGE>
<PAGE>

discretion,  (i)  waive any  assumption  fee, late  payment  or other  charge in
connection with a Mortgage Loan and (ii) to the extent not inconsistent with the
coverage of such  Mortgage Loan  by a  Mortgage Pool  Insurance Policy,  Primary
Mortgage  Insurance Policy,  FHA Insurance,  VA Guaranty  or Bankruptcy  Bond or
alternative arrangements, if applicable, arrange with a Mortgagor a schedule for
the liquidation of  delinquencies 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 to cause to  be made Advances, such obligation will  remain
during any period of such an arrangement.
 
     Unless  otherwise specified  in the  related Prospectus  Supplement, in any
case in which  property securing a  conventional Mortgage Loan  has been, or  is
about  to be, conveyed by the Mortgagor, the Master Servicer will, to the extent
it has knowledge of such conveyance or proposed conveyance, exercise or cause to
be exercised its rights to accelerate  the maturity of such Mortgage Loan  under
any  due-on-sale clause  applicable thereto,  but only  if the  exercise of such
rights is permitted by applicable law and will not impair or threaten to  impair
any  recovery  under any  related 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
Mortgage Loan is  insured by  the FHA  or partially  guaranteed by  the VA,  the
Master  Servicer will enter into  or cause to be  entered into an assumption 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  Mortgage Loan  and,  to the  extent  permitted by  applicable  law, the
Mortgagor also 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 Mortgage Loans -- Due-on-Sale Clauses' herein.  In
connection  with any such assumption, the terms of the related Mortgage 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
Mortgage Loans' herein. This approval is usually based on the purchaser's income
and net worth and numerous other factors. Although the Cooperative's approval is
unlikely to be unreasonably withheld or delayed, the necessity of acquiring such
approval  could limit  the number of  potential purchasers for  those shares and
otherwise limit the Trust Fund's ability to sell and realize the value of  those
shares.
 
     In  general, a 'tenant-stockholder' (as  defined in Code Section 216(b)(2))
of a corporation that  qualifies as a  'cooperative housing corporation'  within
the meaning of Code Section 216(b)(1) is allowed a deduction for amounts paid or
accrued   within  his   taxable  year   to  the   corporation  representing  his
proportionate share of certain interest  expenses and certain real estate  taxes
allowable as a deduction under Code Section 216(a) to the corporation under Code
Sections  163 and 164. In order for  a corporation to qualify under Code Section
216(b)(1) for its taxable year in which such items are allowable as a  deduction
to the corporation, such Section requires, among other things, that at least 80%
of  the gross income of the  corporation be derived from its tenant-stockholders
(as defined  in Code  Section 216(b)(2)).  By virtue  of this  requirement,  the
status  of  a  corporation  for  purposes  of  Code  Section  216(b)(1)  must be
determined on a year-to-year basis. Consequently, there can be no assurance that
Cooperatives relating to the Cooperative  Loans will qualify under such  Section
for  any particular year. In the event  that such a Cooperative fails to qualify
for one  or  more  years, the  value  of  the collateral  securing  any  related
Cooperative  Loans could be significantly impaired because no deduction would be
allowable to tenant-stockholders under Code Section 216(a) with respect to those
years.  In   view   of  the   significance   of  the   tax   benefits   accorded
tenant-stockholders   of  a  corporation  that   qualifies  under  Code  Section
216(b)(1), the likelihood  that such a  failure would be  permitted to  continue
over a period of years appears remote.
 
HAZARD INSURANCE
 
     The  Master Servicer  will require the  Mortgagor on each  Mortgage Loan to
maintain a hazard insurance  policy providing for no  less than the coverage  of
the  standard form of fire insurance policy with extended coverage customary for
the type of Mortgaged Property in the state in which such Mortgaged Property  is
located. Such coverage will be in an amount that is at least equal to the lesser
of  (i) the maximum  insurable value of the  improvements securing such Mortgage
Loan or  (ii)  the greater  of  (y) the  outstanding  principal balance  of  the
Mortgage  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 Mortgaged
Property or released to the Mortgagor  in accordance with the Master  Servicer's
normal  servicing  procedures)  will  be deposited  in  the  related Certificate
Account.  In  the   event  that   the  Master  Servicer   maintains  a   blanket
 
                                       41
 

<PAGE>
<PAGE>

policy  insuring against hazard losses on all the Mortgage Loans comprising part
of a Trust Fund, it will conclusively be deemed to have satisfied its obligation
relating to the maintenance of hazard insurance. Such blanket policy may contain
a deductible  clause, in  which case  the Master  Servicer will  be required  to
deposit from its own funds into the related Certificate Account the amounts that
would have been deposited therein but for such clause.
 
     In  general, the standard form of  fire and extended coverage policy covers
physical damage to or destruction of  the improvements securing a Mortgage  Loan
by fire, lightning, explosion, smoke, windstorm and hail, riot, strike and civil
commotion,  subject  to the  conditions  and exclusions  particularized  in each
policy. Although  the policies  relating to  the Mortgage  Loans may  have  been
underwritten by different insurers under different state laws in accordance with
different  applicable forms  and therefore may  not contain  identical terms and
conditions, the basic terms thereof are  dictated by the respective state  laws,
and most such policies typically do not cover any physical damage resulting from
the  following: war, revolution,  governmental actions, floods  and other water-
related causes,  earth  movement  (including  earthquakes,  landslides  and  mud
flows),  nuclear reactions, wet or dry rot, vermin, rodents, insects or domestic
animals, theft and, in  certain cases, vandalism. The  foregoing list is  merely
indicative  of certain kinds  of uninsured risks  and is not  intended to be all
inclusive. If the Mortgaged  Property securing a Mortgage  Loan is located in  a
federally  designated special flood area at  the time of origination, the Master
Servicer will require the Mortgagor to obtain and maintain flood insurance.
 
     The hazard  insurance policies  covering properties  securing the  Mortgage
Loans  typically contain a  clause which in  effect requires the  insured at all
times to carry insurance of a specified percentage (generally 80% to 90%) of the
full replacement value  of the  insured property in  order to  recover the  full
amount of any partial loss. If the insured's coverage falls below this specified
percentage,  then the insurer's liability in the  event of partial loss will not
exceed the larger of (i) the actual cash value (generally defined as replacement
cost at  the  time  and  place  of loss,  less  physical  depreciation)  of  the
improvements  damaged or destroyed  or (ii) such  proportion of the  loss as the
amount of  insurance carried  bears  to the  specified  percentage of  the  full
replacement  cost of such improvements. Since the amount of hazard insurance the
Master Servicer may  cause to  be maintained  on the  improvements securing  the
Mortgage  Loans declines as  the principal balances  owing thereon decrease, and
since improved real estate generally has  appreciated in value over time in  the
past,  the effect of this  requirement in the event of  partial loss may be that
hazard insurance  proceeds will  be insufficient  to restore  fully the  damaged
property.  If specified in  the related Prospectus  Supplement, a special hazard
insurance policy will  be obtained to  insure against certain  of the  uninsured
risks  described  above. See  'Credit  Enhancement --  Special  Hazard Insurance
Policies' herein  and  'Credit  Enhancements  --  Insurance  --  Special  Hazard
Insurance Policy' in the related Prospectus Supplement.
 
     The  Master  Servicer will  not  require that  a  standard hazard  or flood
insurance policy  be maintained  on  the cooperative  dwelling relating  to  any
Cooperative   Loan.  Generally,  the  Cooperative   itself  is  responsible  for
maintenance of hazard insurance  for the property owned  by the Cooperative  and
the  tenant-stockholders of that  Cooperative do not  maintain individual hazard
insurance policies. To the extent, however,  that a Cooperative and the  related
borrower on a Cooperative Loan do not maintain such insurance or do not maintain
adequate  coverage or any insurance proceeds  are not applied to the restoration
of damaged property, any damage to such borrower's cooperative dwelling or  such
Cooperative's  building could significantly  reduce the value  of the collateral
securing such  Cooperative  Loan to  the  extent  not covered  by  other  credit
support.
 
REALIZATION UPON DEFAULTED MORTGAGE LOANS
 
     Primary  Mortgage Insurance Policies.  The Master Servicer will maintain or
cause to be maintained,  as the case may  be, in full force  and effect, to  the
extent  specified  in  the  related Prospectus  Supplement,  a  Primary Mortgage
Insurance Policy with regard  to each Mortgage Loan  for which such coverage  is
required.  The  Master Servicer  will not  cancel  or refuse  to renew  any such
Primary Mortgage Insurance Policy in effect at the time of the initial  issuance
of  a Series  of Certificates  that is required  to be  kept in  force under the
applicable Agreement unless  the replacement Primary  Mortgage Insurance  Policy
for  such cancelled  or nonrenewed  policy is  maintained with  an insurer whose
claims-paying ability  is  sufficient to  maintain  the current  rating  of  the
classes of Certificates of such Series that have been rated.
 
     Although  the terms and conditions of  primary mortgage insurance vary, the
amount of  a  claim for  benefits  under  a Primary  Mortgage  Insurance  Policy
covering  a Mortgage Loan will  consist of the insured  percentage of the unpaid
principal amount of the  covered Mortgage Loan and  accrued and unpaid  interest
thereon  and  reimbursement of  certain expenses,  less (i)  all rents  or other
payments collected or received by the insured (other than the proceeds of hazard
insurance) that  are  derived  from or  in  any  way related  to  the  Mortgaged
Property,  (ii) hazard  insurance proceeds in  excess of the  amount required to
restore the Mortgaged Property and which have not been applied to the payment of
the  Mortgage   Loan,  (iii)   amounts  expended   but  not   approved  by   the
 
                                       42
 

<PAGE>
<PAGE>

issuer of the related Primary Mortgage Insurance Policy (the 'Primary Insurer'),
(iv)  claim  payments previously  made  by the  Primary  Insurer and  (v) unpaid
premiums.
 
     Primary Mortgage Insurance Policies  reimburse certain losses sustained  by
reason of defaults in payments by borrowers. Primary Mortgage Insurance Policies
will  not insure against, and exclude from  coverage, a loss sustained by reason
of a default arising from or  involving certain matters, including (i) fraud  or
negligence  in  origination  or  servicing  of  the  Mortgage  Loans,  including
misrepresentation by the originator, Mortgagor or other persons involved in  the
origination  of  the  Mortgage Loan;  (ii)  failure to  construct  the Mortgaged
Property subject to the Mortgage Loan in accordance with specified plans;  (iii)
physical damage to the Mortgaged Property; and (iv) the related Sub-Servicer not
being approved as a servicer by the Primary Insurer.
 
     Recoveries  Under  a  Primary  Mortgage Insurance  Policy.    As conditions
precedent to  the filing  of or  payment of  a claim  under a  Primary  Mortgage
Insurance  Policy covering a Mortgage Loan, the  insured will be required to (i)
advance or  discharge  (a) all  hazard  insurance  policy premiums  and  (b)  as
necessary  and  approved in  advance  by the  Primary  Insurer, (1)  real estate
property taxes,  (2) all  expenses required  to maintain  the related  Mortgaged
Property  in at least  as good a condition  as existed at  the effective date of
such Primary Mortgage  Insurance Policy,  ordinary wear and  tear excepted,  (3)
Mortgaged Property sales expenses, (4) any outstanding liens (as defined in such
Primary Mortgage Insurance Policy) on the Mortgaged Property and (5) foreclosure
costs,  including court costs and reasonable  attorneys' fees; (ii) in the event
of any physical  loss or damage  to the Mortgaged  Property, have the  Mortgaged
Property restored and repaired to at least as good a condition as existed at the
effective date of such Primary Mortgage Insurance Policy, ordinary wear and tear
excepted; and (iii) tender to the Primary Insurer good and merchantable title to
and possession of the Mortgaged Property.
 
     The   Master  Servicer,   on  behalf  of   itself,  the   Trustee  and  the
Certificateholders, will  present  claims  to the  insurer  under  each  Primary
Mortgage  Insurance Policy, and will take such reasonable steps as are necessary
to receive payment or  to permit recovery thereunder  with respect to  defaulted
Mortgage  Loans. As  set forth  above, all  collections by  or on  behalf of the
Master Servicer  under  any Primary  Mortgage  Insurance Policy  and,  when  the
Mortgaged Property has not been restored, the hazard insurance policy, are to be
deposited  in  the  Certificate  Account, subject  to  withdrawal  as heretofore
described.
 
     If the Mortgaged Property securing a defaulted Mortgage Loan is damaged and
proceeds, if any, from the related  hazard insurance policy are insufficient  to
restore  the  damaged Mortgaged  Property to  a  condition sufficient  to permit
recovery under the related Primary Mortgage Insurance Policy, if any, the Master
Servicer is  not  required  to expend  its  own  funds to  restore  the  damaged
Mortgaged  Property unless it determines (i) that such restoration will increase
the proceeds to  Certificateholders on  liquidation of the  Mortgage Loan  after
reimbursement  of  the  Master Servicer  for  its  expenses and  (ii)  that such
expenses  will  be  recoverable  by  it  from  related  Insurance  Proceeds   or
Liquidation Proceeds.
 
     If recovery on a defaulted Mortgage Loan under any related Primary Mortgage
Insurance  Policy is not  available for the  reasons set forth  in the preceding
paragraph, or  if  the defaulted  Mortgage  Loan is  not  covered by  a  Primary
Mortgage  Insurance Policy, the  Master Servicer will be  obligated to follow or
cause to be followed such normal practices and procedures as it deems  necessary
or advisable to realize upon the defaulted Mortgage Loan. If the proceeds of any
liquidation  of the Mortgaged Property securing  the defaulted Mortgage Loan are
less than the  principal balance  of such  Mortgage Loan  plus interest  accrued
thereon  that is  payable to Certificateholders,  the Trust Fund  will realize a
loss in the amount of such difference plus the aggregate of expenses incurred by
the Master Servicer in  connection with such  proceedings that 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 Mortgage Loan plus interest
accrued thereon that is payable to Certificateholders, the Master Servicer  will
be  entitled  to  withdraw  or  retain  from  the  Certificate  Account  amounts
representing its normal  servicing compensation  with respect  to such  Mortgage
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  Mortgagor,  as additional
servicing compensation.
 
     If the Master Servicer or  its designee recovers Insurance Proceeds  which,
when  added to any  related Liquidation Proceeds and  after deduction of certain
expenses reimbursable to the Master Servicer, exceed the principal balance of  a
Mortgage   Loan   plus   interest   accrued   thereon   that   is   payable   to
Certificateholders, the Master Servicer will  be entitled to withdraw or  retain
from   the  Certificate  Account  amounts   representing  its  normal  servicing
compensation with respect to  such Mortgage Loan. In  the event that the  Master
Servicer  has expended its  own funds to restore  the damaged Mortgaged Property
and such  funds have  not been  reimbursed under  the related  hazard  insurance
policy,  it will  be entitled  to withdraw from  the Certificate  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
 
                                       43
 

<PAGE>
<PAGE>

deficiency  claims and certain expenses incurred by the Master Servicer, no such
payment or recovery will result in a recovery to the Trust Fund that exceeds the
principal balance of the defaulted Mortgage Loan together with accrued  interest
thereon.   See  'Credit  Enhancement'  herein  and  in  the  related  Prospectus
Supplement.
 
     Unless otherwise  specified in  the related  Prospectus Supplement  or  the
related  Agreement, the proceeds from any liquidation of a Mortgage 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
Mortgaged Property and  any unreimbursed servicing  compensation payable to  the
Master  Servicer with  respect to such  Mortgage Loan; second,  to reimburse the
Master Servicer  for any  unreimbursed Advances  with respect  to such  Mortgage
Loan;  third, to accrued and unpaid interest  (to the extent no Advance has been
made for  such amount)  on such  Mortgage Loan;  and fourth,  as a  recovery  of
principal of such Mortgage Loan.
 
     FHA  Insurance; VA  Guaranties.  Mortgage  Loans designated  in the related
Prospectus Supplement  as insured  by the  FHA will  be insured  by the  FHA  as
authorized  under  the  United States  Housing  Act  of 1937,  as  amended. Such
Mortgage Loans will be insured under various FHA programs including the standard
FHA 203(b)  program to  finance the  acquisition of  one-to four-family  housing
units  and  the  FHA  245 graduated  payment  mortgage  program.  These programs
generally limit the principal  amount and interest rates  of the mortgage  loans
insured.  Mortgage Loans  insured by  the FHA  generally require  a minimum down
payment of approximately  5% of the  original principal amount  of the loan.  No
FHA-insured  Mortgage Loans relating  to a Series  may have an  interest rate or
original principal amount  exceeding the applicable  FHA limits at  the time  of
origination of such loan.
 
     The  insurance premiums for Mortgage Loans insured by the FHA are collected
by lenders approved by the Department  of Housing and Urban Development  ('HUD')
or  by the  Master Servicer or  any Sub-Servicers and  are paid to  the FHA. The
regulations governing FHA single-family mortgage insurance programs provide that
insurance benefits are payable either upon foreclosure (or other acquisition  of
possession)  and conveyance of the mortgaged  premises to HUD or upon assignment
of the defaulted Mortgage Loan to  HUD. With respect to a defaulted  FHA-insured
Mortgage Loan, the Master Servicer or any Sub-Servicer is limited in its ability
to initiate foreclosure proceedings. When it is determined, either by the Master
Servicer  or any Sub-Servicer  or HUD, that default  was caused by circumstances
beyond the  Mortgagor's control,  the  Master Servicer  or any  Sub-Servicer  is
expected  to make an effort to avoid  foreclosure by entering, if feasible, into
one of a number of available forms of forbearance plans with the Mortgagor. Such
plans may involve the reduction or suspension of regular mortgage payments for a
specified period, with such  payments to be  made up on  or before the  maturity
date  of the mortgage, or the recasting of payments due under the mortgage up to
or beyond  the  maturity  date. In  addition,  when  a default  caused  by  such
circumstances  is accompanied by certain other  criteria, HUD may provide relief
by making payments to the Master Servicer or any Sub-Servicer in partial or full
satisfaction of amounts due  under the Mortgage Loan  (which payments are to  be
repaid  by the Mortgagor to HUD) or by accepting assignment of the loan from the
Master Servicer or  any Sub-Servicer.  With certain exceptions,  at least  three
full monthly installments must be due and unpaid under the Mortgage Loan and HUD
must  have rejected any request for relief  from the Mortgagor before the Master
Servicer or any Sub-Servicer may initiate foreclosure proceedings.
 
     HUD has the option, in  most cases, to pay insurance  claims in cash or  in
debentures  issued by HUD. Currently, claims are  being paid in cash, and claims
have  not  been  paid  in  debentures  since  1965.  HUD  debentures  issued  in
satisfaction  of  FHA  insurance  claims bear  interest  at  the  applicable HUD
debentures interest  rate.  The Master  Servicer  of any  Sub-Servicer  of  each
FHA-insured  Mortgage  Loan will  be obligated  to  purchase any  such debenture
issued in satisfaction of such Mortgage Loan upon default for an amount equal to
the principal amount of any such debenture.
 
     The amount of insurance benefits generally paid by the FHA is equal to  the
entire  unpaid  principal  amount of  the  defaulted Mortgage  Loan  adjusted to
reimburse the Master Servicer or Sub-Servicer for certain costs and expenses and
to deduct  certain  amounts received  or  retained  by the  Master  Servicer  or
Sub-Servicer  after default. When entitlement to insurance benefits results from
foreclosure (or  other acquisition  of possession)  and conveyance  to HUD,  the
Master  Servicer or Sub-Servicer  is compensated for no  more than two-thirds of
its foreclosure costs, and is compensated for interest accrued and unpaid  prior
to  such date but  in general only  to the extent  it was allowed  pursuant to a
forbearance plan approved by HUD. When entitlement to insurance benefits results
from assignment of the Mortgage Loan to HUD, the insurance payment includes full
compensation for  interest  accrued  and  unpaid to  the  assignment  date.  The
insurance  payment  itself, upon  foreclosure of  an FHA-insured  Mortgage Loan,
bears interest  from a  date 30  days after  the Mortgagor's  first  uncorrected
failure  to perform any  obligation to make  any payment due  under the Mortgage
Loan and, upon assignment, from the date of assignment to the date of payment of
the claim,  in  each case  at  the same  interest  rate as  the  applicable  HUD
debenture interest rate as described above.

     Mortgage   Loans  designated  in  the   related  Prospectus  Supplement  as
guaranteed by  the  VA  will  be  partially  guaranteed  by  the  VA  under  the
Serviceman's  Readjustment  Act  of  1944, as  amended  (a  'VA  Guaranty'). 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
guarantee  of mortgage loans of  up to 30 years'  duration. However, no Mortgage
Loan guaranteed by the  VA will have an  original principal amount greater  than
five times the partial VA guaranty for such Mortgage 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. As of
January  1, 1990, the maximum guaranty  that may be issued by  the VA under a VA
guaranteed mortgage loan  of more  than $144,000  is the  lesser of  25% of  the
original principal amount of the mortgage loan and $46,000. The liability on the
guaranty  is reduced or increased pro rata with any reduction or increase in the
amount of indebtedness, but in no event will the amount payable on the  guaranty
exceed  the  amount of  the original  guaranty. The  VA may,  at its  option and
without regard  to the  guaranty, make  full  payment to  a mortgage  holder  of
unsatisfied indebtedness on a mortgage upon its assignment to the VA.
 
     With  respect  to  a  defaulted VA  guaranteed  Mortgage  Loan,  the Master
Servicer or  Sub-Servicer is,  absent exceptional  circumstances, authorized  to
announce  its intention  to foreclose  only when  the default  has continued for
three months. Generally, a claim for the guaranty is submitted after liquidation
of the Mortgaged Property.
 
     The amount  payable  under the  guaranty  will  be the  percentage  of  the
VA-insured   Mortgage  Loan   originally  guaranteed   applied  to  indebtedness
outstanding as  of  the applicable  date  of  computation specified  in  the  VA
regulations.  Payments under the guaranty will  be equal to the unpaid principal
amount of the loan, interest  accrued on the unpaid balance  of the loan to  the
appropriate  date of computation  and limited expenses of  the mortgagee, but in
each case only to the extent that  such amounts have not been recovered  through
liquidation of the Mortgaged Property. The amount payable under the guaranty may
in no event exceed the amount of the original guaranty.
 
SERVICING AND OTHER COMPENSATION AND PAYMENT OF EXPENSES
 
     The  principal servicing compensation to be  paid to the Master Servicer in
respect of its master servicing activities for each Series of Certificates  will
be  equal  to  the percentage  per  annum  described in  the  related Prospectus
Supplement (which  may  vary under  certain  circumstances) of  the  outstanding
principal  balance of each Mortgage Loan, and such compensation will be retained
by it from collections of  interest on such Mortgage  Loan in the related  Trust
Fund  (the 'Master  Servicing Fee'). Unless  otherwise specified  in the related
Prospectus Supplement, as compensation for its servicing duties, 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 a  Sub-Servicer  will retain  all prepayment
charges, assumption fees and late payment charges, to the extent collected  from
Mortgagors,  and any benefit  that may accrue  as a result  of the investment of
funds in the applicable Certificate  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. In addition, as indicated in the preceding
section, the  Master Servicer  will  be entitled  to reimbursement  for  certain
expenses  incurred by it  in connection with  any defaulted Mortgage  Loan as to
which it has determined that all recoverable Liquidation Proceeds and  Insurance
Proceeds  have been received  (a 'Liquidated Mortgage'),  and in connection with
the restoration of Mortgaged Properties, such right of reimbursement being prior
to the rights of Certificateholders to receive any related Liquidation  Proceeds
(including Insurance Proceeds).
 
EVIDENCE AS TO COMPLIANCE
 
     Each  Agreement will  provide that  on or before  a specified  date in each
year, 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 firm
conducted substantially in compliance with the Uniform Single Audit Program  for
Mortgage  Bankers or  the Audit  Program for  Mortgages serviced  for FHLMC, the
servicing by or on behalf of the Master Servicer of
 
                                       45
 

<PAGE>
<PAGE>

Mortgage Loans, Private Mortgage-Backed  Securities or Agency Securities,  under
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 Audit Program for
Mortgage Bankers requires it to report. In rendering its statement such firm may
rely,  as to matters relating to the direct servicing of Mortgage Loans, Private
Mortgage-Backed  Securities  or   Agency  Securities   by  Sub-Servicers,   upon
comparable  statements  for examinations  conducted substantially  in compliance
with the Uniform Single Audit 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 Certificateholders  of the  related
Series without charge upon written request to the Master Servicer at the address
set forth in the related Prospectus Supplement.
 
LIST OF CERTIFICATEHOLDERS
 
     Each  Agreement will provide that three  or more holders of Certificates of
any Series 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.
 
CERTAIN MATTERS REGARDING THE MASTER SERVICER AND THE DEPOSITOR
 
     The  Master  Servicer under  each Agreement  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
the  performance by it of  its duties thereunder is  no longer permissible under
applicable law. No such resignation will become effective until the Trustee or a
successor servicer  has assumed  the Master  Servicer's obligations  and  duties
under the Agreement.
 
     Each  Agreement will further provide that  neither the Master Servicer, the
Depositor nor any director, officer, employee,  or agent of the Master  Servicer
or  the  Depositor will  be under  any liability  to the  related Trust  Fund or
Certificateholders for any action taken or for refraining from the taking of any
action in  good faith  pursuant to  the Agreement,  or for  errors in  judgment;
provided,  however, that neither the Master Servicer, the Depositor nor any such
person will be protected against any  liability that would otherwise be  imposed
by  reason of willful misfeasance, bad faith or 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  Certificates,
other than any loss, liability or expense related to any specific Mortgage Asset
or  Mortgage  Assets  (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 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 Certificateholders thereunder.
In such event, the  legal expenses and  costs of such  action and any  liability
resulting  therefrom will be expenses, costs  and liabilities of the Trust Fund,
and the Master Servicer or the Depositor,  as the case may be, will be  entitled
to   be   reimbursed  therefor   out   of  funds   otherwise   distributable  to
Certificateholders.
 
     Any person into which the Master Servicer may be merged or consolidated, or
any person  resulting from  any  merger or  consolidation  to which  the  Master
Servicer  is a  party, or any  person succeeding  to the business  of the Master
Servicer, will be  the successor of  the Master Servicer  under each  Agreement,
provided  that such person is  qualified to sell mortgage  loans to, and service
mortgage loans on behalf of, FNMA or FHLMC and
 
                                       46
 

<PAGE>
<PAGE>

further  provided  that  such  merger,  consolidation  or  succession  does  not
adversely  affect the then current rating or  ratings of the class or classes of
Certificates of such Series that have been rated.
 
EVENTS OF DEFAULT
 
     Unless 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 Certificateholders of  any
class  any required payment  (other than an  Advance) which continues unremedied
for five business days after the giving of written notice of such failure to the
Master Servicer by the Trustee or the Depositor, or to the Master Servicer,  the
Depositor  and  the  Trustee  by  the  holders  of  Certificates  of  such class
evidencing the right to not less  than 25% of the total distributions  allocated
to  such  class (the  'Percentage  Interest'); (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
Certificates  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 Mortgage Assets and the other assets of the Trust
Fund in the  event that  payments in respect  thereto are  insufficient to  make
payments  required in the Agreement.  The assets of the  Trust Fund will be sold
only under  the  circumstances  and  in the  manner  specified  in  the  related
Prospectus Supplement.
 
RIGHTS UPON EVENT OF DEFAULT
 
     So  long as an Event of Default  under an Agreement remains unremedied, the
Depositor or the Trustee  may, and at the  direction of holders of  Certificates
having 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
Mortgage  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  at 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  to  the successor  servicer, which  in no  event may  be greater  than the
compensation payable to the Master Servicer under the Agreement.
 
     No Certificateholder,  solely  by  virtue  of such  holder's  status  as  a
Certificateholder,  will have  any right  under any  Agreement to  institute any
proceeding with respect  to such  Agreement, unless such  holder previously  has
given  to the Trustee  written notice of  default and unless  the holders of any
class of  Certificates  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.
 
AMENDMENT
 
     Unless otherwise  specified  in  the related  Prospectus  Supplement,  each
Agreement  may be amended by the Depositor, the Master Servicer and the Trustee,
without the consent of any of the Certificateholders, (i) to cure any ambiguity;
(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  that
are not inconsistent with the provisions thereof, provided that such action will
not   adversely  affect   in  any   material  respect   the  interests   of  any
Certificateholder. An amendment will  be deemed to not  adversely affect in  any
material   respect  the  interests  of  the  Certificateholders  if  the  person
requesting such amendment obtains a letter from each rating agency requested  to
rate  the class  or classes  of Certificates  of such  Series stating  that such
amendment will not  result in the  downgrading or withdrawal  of the  respective
ratings  then assigned to such Certificates. In addition, to the extent provided
in the related Agreement, an Agreement may be amended without the consent of any
of   the   Certificateholders    to   change   the    manner   in   which    the
 
                                       47
 

<PAGE>
<PAGE>

Certificate  Account  is  maintained, provided  that  any such  change  does not
adversely affect the then current rating of the class or classes of Certificates
of such Series that have  been rated. In addition, if  a REMIC election is  made
with  respect to a Trust  Fund, the related Agreement  may be amended to modify,
eliminate or add to any of its provisions to such extent as may be necessary  to
maintain  the qualification of the related Trust  Fund as a REMIC, provided that
the Trustee has received an opinion of counsel to the effect that such action is
necessary or helpful to maintain such qualification. Unless otherwise  specified
in  the related Prospectus Supplement, each Agreement may also be amended by the
Depositor, the Master Servicer  and the Trustee with  the consent of holders  of
Certificates  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 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  received on
Mortgage Assets that are required to  be distributed on any Certificate  without
the  consent of  the holder  of such  Certificate or  (ii) reduce  the aforesaid
percentage of Certificates of any class  of holders that is required to  consent
to  any such amendment without the consent of the holders of all Certificates of
such class covered by  such Agreement then outstanding.  If a REMIC election  is
made  with respect to a Trust Fund, the  Trustee will not be entitled to consent
to an  amendment to  the  related Agreement  without  having first  received  an
opinion  of counsel to the effect that  such amendment will not cause such Trust
Fund to fail to qualify as a REMIC.
 
TERMINATION; OPTIONAL TERMINATION
 
     Unless otherwise  specified  in  the  related  Agreement,  the  obligations
created  by each Agreement  for each Series of  Certificates will terminate upon
the payment  to  the related  Certificateholders  of  all amounts  held  in  the
Certificate  Account or by the  Master Servicer and required  to be paid to them
pursuant to such Agreement following the later of (i) the final payment or other
liquidation  of  the  last  of  the  Mortgage  Assets  subject  thereto  or  the
disposition  of  all property  acquired upon  foreclosure  of any  such Mortgage
Assets remaining in the Trust Fund and (ii) the purchase by the Master  Servicer
or,  if  REMIC  treatment has  been  elected  and if  specified  in  the related
Prospectus Supplement, by the holder of the residual interest in the REMIC  (see
'Certain  Federal Income Tax  Consequences' below and  in the related Prospectus
Supplement), from the related Trust Fund of all of the remaining Mortgage Assets
and all property acquired in respect of such Mortgage Assets.
 
     Unless otherwise  specified  in  the  related  Prospectus  Supplement,  any
purchase  of Mortgage Assets and property acquired in respect of Mortgage Assets
evidenced by a Series of Certificates will  be made at the option of the  Master
Servicer  or, if  applicable, the  holder of the  REMIC residual  interest, at a
price,  and  in  accordance  with  the  procedures,  specified  in  the  related
Prospectus  Supplement. The exercise of such  right will effect early retirement
of the Certificates of that Series, but the right of the Master Servicer or,  if
applicable,  such  holder of  the  REMIC residual  interest,  to so  purchase is
subject to the principal balance of the related Mortgage Assets being less  than
the  percentage specified in the related  Prospectus Supplement of the aggregate
principal balance of the Mortgage Assets at the Cut-off Date for the Series. The
foregoing is subject  to the provision  that if  a REMIC election  is made  with
respect  to a Trust Fund,  any repurchase pursuant to  clause (ii) above will be
made only in connection with a  'qualified liquidation' of the REMIC within  the
meaning of Section 860F(g)(4) of the Code.
 
THE TRUSTEE
 
     The Trustee under each Agreement will be named in the applicable Prospectus
Supplement.  The commercial  bank or trust  company serving as  Trustee may have
normal banking relationships with the Depositor, the Master Servicer and any  of
their respective affiliates.
 
                  CERTAIN LEGAL ASPECTS OF THE MORTGAGE LOANS
 
     The  following discussion contains summaries,  which are general in nature,
of certain legal  matters relating  to the  Mortgage Loans.  Because such  legal
aspects  are governed primarily  by applicable state law  (which laws may differ
substantially), the summaries do  not purport to be  complete or to reflect  the
laws of any particular state or to encompass the laws of all states in which the
security  for the  Mortgage Loans  is situated.  The summaries  are qualified in
their entirety  by reference  to the  appropriate laws  of the  states in  which
Mortgage Loans may be originated.
 
GENERAL
 
     The  Mortgage Loans will be secured  by deeds of trust, mortgages, security
deeds or deeds  to secure debt,  depending upon the  prevailing practice in  the
state  in  which  the  property  subject  to  the  loan  is  located.  Deeds  of
 
                                       48
 

<PAGE>
<PAGE>

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 Mortgage Loans may be Cooperative Loans. The
Cooperative owns all the real property that comprises the project, including the
land, separate dwelling units and all common areas. The Cooperative is  directly
responsible  for project management  and, in most cases,  payment of real estate
taxes and hazard and liability insurance. If there is a blanket mortgage on  the
Cooperative  and/or underlying land, as is  generally the case, the Cooperative,
as  project  mortgagor,   is  also  responsible   for  meeting  these   mortgage
obligations.  A blanket  mortgage is ordinarily  incurred by  the Cooperative in
connection with  the construction  or purchase  of the  Cooperative's  apartment
building.  The interest  of the occupant  under proprietary  leases or occupancy
agreements to which that Cooperative is a party are generally subordinate to the
interest of  the  holder  of the  blanket  mortgage  in that  building.  If  the
Cooperative  is unable to meet the payment obligations arising under its blanket
mortgage, the mortgagee  holding the  blanket mortgage could  foreclose on  that
mortgage   and  terminate  all  subordinate  proprietary  leases  and  occupancy
agreements. In  addition, the  blanket  mortgage on  a Cooperative  may  provide
financing  in  the  form of  a  mortgage that  does  not fully  amortize  with a
significant portion of principal  being due in one  lump sum at final  maturity.
The  inability of the Cooperative to  refinance this mortgage and its consequent
inability to make such final payment could lead to foreclosure by the  mortgagee
providing  the financing.  A foreclosure  in either event  by the  holder of the
blanket mortgage  could eliminate  or significantly  diminish the  value of  any
collateral  held  by  the lender  who  financed  the purchase  by  an individual
tenant-stockholder of  Cooperative  shares or,  in  the  case of  a  Trust  Fund
including Cooperative Loans, the collateral securing the Cooperative Loans.
 
     The  Cooperative is owned by  tenant-stockholders who, through ownership of
stock, shares or membership certificates in the corporation, receive proprietary
leases or occupancy agreements which confer exclusive rights to occupy  specific
units.  Generally, a  tenant-stockholder of  a Cooperative  must make  a monthly
payment to the Cooperative representing such tenant-stockholder's pro rata share
of the Cooperative's  payments for  its blanket mortgage,  real property  taxes,
maintenance  expenses  and  other  capital or  ordinary  expenses.  An ownership
interest in  a  Cooperative  and  accompanying  rights  is  financed  through  a
Cooperative  share loan evidenced by a promissory note and secured by a security
interest in the  occupancy agreement  or 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/REPOSSESSION
 
     Deed of Trust.  Foreclosure of a deed of trust is generally accomplished by
a  non-judicial  sale under  a specific  provision  in the  deed of  trust which
authorizes the trustee to sell the  property at public auction upon any  default
by the borrower under the terms of the note or deed of trust. In certain states,
such  foreclosure  also may  be accomplished  by judicial  action in  the manner
provided for foreclosure of mortgages. In  some states, such as California,  the
trustee  must record a notice of default and send a copy to the borrower-trustor
and to any person who has recorded a request for a copy of any notice of default
and notice of sale. In addition, the trustee must
 
                                       49
 

<PAGE>
<PAGE>

provide notice in  some states  to any other  individual having  an interest  of
record  in the real property,  including any junior lienholders.  If the deed of
trust is not reinstated within any applicable cure period, a notice of sale must
be posted in a public place and, in most states, including California, published
for a specified period  of time in  one or more  newspapers. In addition,  these
notice  provisions require that  a copy of the  notice of sale  be posted on the
property and sent to all parties having  an interest of record in the  property.
In  California,  the entire  process from  recording  a notice  of default  to a
non-judicial sale usually takes four to five months.
 
     In some states, including California, the borrower-trustor has the right to
reinstate the  loan at  any  time following  default  until shortly  before  the
trustee's  sale. In general, the  borrower, or any other  person having a junior
encumbrance on the  real estate, may,  during a reinstatement  period, cure  the
default  by paying  the entire  amount in  arrears plus  the costs  and expenses
incurred in enforcing the obligation. Certain  state laws control the amount  of
foreclosure  expenses  and  costs,  including  attorney's  fees,  which  may  be
recoverable by a lender.
 
     Mortgages.  Foreclosure of a mortgage is generally accomplished by judicial
action. The  action is  initiated by  the service  of legal  pleadings upon  all
parties  having an interest  in the real  property. Delays in  completion of the
foreclosure may  occasionally result  from  difficulties in  locating  necessary
parties.  Judicial foreclosure proceedings 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 general, the borrower, or any other person having a
junior  encumbrance on  the real  estate, may,  during a  statutorily prescribed
reinstatement period, cure  a monetary default  by paying the  entire amount  in
arrears  plus  other designated  costs and  expenses  incurred in  enforcing the
obligation. Generally, state law controls the amount of foreclosure expenses and
costs, including attorney's fees, which may be recovered by a lender. After  the
reinstatement  period has  expired without  the default  having been  cured, the
borrower or junior lienholder no longer has the right to reinstate the loan  and
must pay the loan in full to prevent the scheduled foreclosure sale. If the deed
of  trust is not reinstated, a  notice of sale must be  posted in a public place
and, in most  states, published for  a specific period  of time in  one or  more
newspapers.  In addition, some state  laws require that a  copy of the notice of
sale be posted on the property and sent to all parties having an interest in the
real property.
 
     Although foreclosure sales are typically public sales, frequently no  third
party purchaser bids in excess of the lender's lien because of the 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. Thereafter,
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.
 
     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.
 
     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.
 
                                       50
 

<PAGE>
<PAGE>

     The recognition agreement generally  provides that, in  the event that  the
tenant-stockholder  has  defaulted  under  the  proprietary  lease  or occupancy
agreement, the  Cooperative will  take  no action  to  terminate such  lease  or
agreement  until the lender  has been provided  with an opportunity  to cure the
default. The recognition  agreement typically provides  that if the  proprietary
lease  or occupancy agreement is terminated,  the Cooperative will recognize the
lender's lien  against proceeds  from  the sale  of the  Cooperative  apartment,
subject,  however, to the Cooperative's right to sums due under such proprietary
lease or occupancy agreement.  The total amount owed  to the Cooperative by  the
tenant-stockholder,  which  the lender  generally cannot  restrict and  does not
monitor, could  reduce  the  value  of  the  collateral  below  the  outstanding
principal  balance  of  the Cooperative  Loan  and accrued  and  unpaid interest
thereon.
 
     Recognition agreements also provide that in the event of a foreclosure on a
Cooperative Loan,  the  lender  must  obtain the  approval  or  consent  of  the
Cooperative  as  required  by  the  proprietary  lease  before  transferring the
Cooperative shares or assigning the proprietary lease. Generally, the lender  is
not limited in any rights it may have to dispossess the tenant-stockholders.
 
     In  some states, foreclosure on the Cooperative shares is accomplished by a
sale in accordance with  the provisions of Article  9 of the Uniform  Commercial
Code  (the 'UCC') and the security agreement relating to those shares. Article 9
of the UCC  requires that  a sale be  conducted in  a 'commercially  reasonable'
manner.  Whether  a  foreclosure  sale has  been  conducted  in  a 'commercially
reasonable' manner  will  depend on  the  facts  in each  case.  In  determining
commercial  reasonableness, a court will look to the notice given the debtor and
the method, manner, time, place and terms of the foreclosure. Generally, a  sale
conducted  according to the  usual practice of  banks selling similar collateral
will be considered reasonably conducted.
 
     Article 9 of the UCC provides that the proceeds of the sale will be applied
first to  pay the  costs  and expenses  of  the sale  and  then to  satisfy  the
indebtedness   secured  by  the  lender's  security  interest.  The  recognition
agreement, however, generally provides that the lender's right to  reimbursement
is  subject  to the  right  of the  Cooperative to  receive  sums due  under the
proprietary lease or occupancy agreement.  If there are proceeds remaining,  the
lender  must account to the tenant-stockholder for the surplus. Conversely, if a
portion of the indebtedness remains unpaid, the tenant-stockholder is  generally
responsible  for  the  deficiency. See  'Anti-Deficiency  Legislation  and Other
Limitations on Lenders' below.
 
     In the case of foreclosure on a building which was converted from a  rental
building  to a building owned  by a Cooperative under  a non-eviction plan, some
states require that a purchaser at a foreclosure sale take the property  subject
to  rent control and rent stabilization laws  which apply to certain tenants who
elected to  remain in  the  building but  who did  not  purchase shares  in  the
Cooperative when the building was so converted.
 
RIGHTS OF REDEMPTION
 
     In  some states after sale pursuant to a  deed of trust or foreclosure of a
mortgage, the  borrower  and  certain  foreclosed junior  lienors  are  given  a
statutory  period in which to redeem the  property from the foreclosure sale. In
certain other states,  including California,  this right  of redemption  applies
only  to sales following  judicial foreclosure, and  not to sales  pursuant to a
non-judicial power of  sale. In  most states where  the right  of redemption  is
available,  statutory  redemption  may  occur upon  payment  of  the foreclosure
purchase price, accrued interest and taxes. In some states, the right to  redeem
is  an equitable right. The  effect of a right of  redemption is to diminish the
ability of the lender to sell the  foreclosed property. The exercise of a  right
of  redemption would defeat the title of any purchaser at a foreclosure sale, or
of any purchaser  from the  lender subsequent  to judicial  foreclosure or  sale
under  a deed  of trust.  Consequently, the  practical effect  of the redemption
right is to  force the lender  to retain the  property and pay  the expenses  of
ownership until the redemption period has run.
 
ANTI-DEFICIENCY LEGISLATION AND OTHER LIMITATIONS ON LENDERS
 
     Certain  states have imposed statutory restrictions that limit the remedies
of a beneficiary under a deed of trust or a mortgagee under a mortgage. In  some
states,  including California,  statutes limit the  right of  the beneficiary or
mortgagee to  obtain  a  deficiency  judgment  against  the  borrower  following
foreclosure  or sale under a deed of  trust. A deficiency judgment is a personal
judgment against the borrower equal in most cases to the difference between  the
amount  due to the lender  and the current fair market  value of the property at
the time of  the foreclosure  sale. 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 Mortgagors.
 
     Some state statutes may require the beneficiary or mortgagee to exhaust the
security afforded under a deed of trust or mortgage by foreclosure in an attempt
to satisfy the full debt before bringing a personal action against the borrower.
In certain other states, the lender has the option of bringing a personal action
against the borrower
 
                                       51
 

<PAGE>
<PAGE>

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.
 
     In addition  to anti-deficiency  and  related legislation,  numerous  other
federal  and state statutory provisions,  including the federal bankruptcy laws,
the federal  Soldiers' and  Sailors' Civil  Relief Act  of 1940  and state  laws
affording  relief to debtors,  may interfere with  or affect the  ability of the
secured mortgage  lender  to  realize  upon its  security.  For  example,  in  a
proceeding  under the federal Bankruptcy  Code, a lender may  not foreclose on 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  Mortgage
Loans  underlying  a  Series  of Certificates  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. Numerous federal and state consumer protection laws
impose substantive requirements  upon mortgage  lenders in  connection with  the
origination, servicing and enforcement of mortgage loans. These laws include the
federal  Truth-in-Lending  Act,  Real Estate  Settlement  Procedures  Act, Equal
Credit Opportunity Act, Fair Credit Billing  Act, Fair Credit Reporting Act  and
related  statutes and regulations. These federal  and state laws impose specific
statutory liabilities upon lenders who fail to comply with the provisions of the
law. In  some  cases,  this liability  may  affect  assignees of  the  loans  or
contracts.
 
     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.
 
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 the EPA has incurred clean-up costs. However, a CERCLA
lien is subordinate to pre-existing, perfected security interests.
 
     Under the laws of some states, and  under CERCLA, it is conceivable that  a
lender  may be held liable, as an 'owner' or 'operator', for costs of addressing
releases or threatened releases of hazardous substances at a Mortgaged Property,
regardless of whether or not the environmental damage or threat was caused by  a
prior  owner or operator.  CERCLA imposes liability on  any and all 'responsible
parties' (which includes, inter alia, the  property owner and operator) for  the
cost  of clean-up of releases of  hazardous substances. However, CERCLA excludes
from the definition of 'owner or operator' secured creditors who hold indicia of
ownership for the purpose  of protecting their  security interest, but  'without
participating   in  the  management   of  the  facility.'   That  exclusion  was
substantially narrowed by  a May  1990 decision of  the United  States Court  of
Appeals  for the Eleventh Circuit in United States v. Fleet Factors Corp., which
held that a lender need not have involved itself in the day-to-day operations of
the facility or participated in decisions relating to hazardous waste management
in order to  be liable;  rather, liability  could attach  to the  lender if  its
involvement  with the management of the facility  is broad enough to support the
inference that the lender could  affect hazardous waste management practices  if
it  so  chose.  The court  added  that  a lender's  capacity  to  influence such
decisions could be inferred from the extent of its involvement in the facility's
financial  management.  In  response  to  Fleet  Factors,  the  EPA  promulgated
regulations  designed to clarify the range of  activities a lender may engage in
without losing the
 
                                       52
 

<PAGE>
<PAGE>

benefit of the statutory exclusion. Under the regulations, which took effect  in
April  1992,  a  lender is  permitted  to monitor  the  borrower's environmental
practices in order to determine if the facility is in compliance with applicable
law, and  to require  the borrower  to  take measures  necessary to  achieve  or
maintain compliance or conduct necessary clean-ups. The lender may not, however,
exercise  control over or assume responsibility for the borrower's environmental
practices. Such actions would be considered 'participation in the management  of
the facility'. Also, if the lender takes title to or possession of the property,
it  might be deemed to  have obviated the security  interest exclusion and to be
liable for clean-up costs pursuant to CERCLA. The EPA regulations allow  lenders
to  take certain actions with respect  to foreclosure without losing the benefit
of the statutory  exclusion. Essentially,  the regulations allow  the lender  to
take  actions consistent with protecting its  security interest, but not actions
which demonstrate  an intent  to exercise  long-term ownership  interest in  the
property. While the EPA regulations offer some protection to lenders, it must be
noted  that such  protection may  not be  available under  applicable state law.
Furthermore, the regulations  are binding only  on the EPA  with respect to  the
EPA's  enforcement  powers  and  cost  recovery  rights.  It  has  not  yet been
determined whether  the  federal  courts  will apply  the  regulations  in  cost
recovery  actions brought against lenders by other responsible parties, although
the regulations may well be considered  persuasive by the courts. (Two  judicial
challenges  have been brought  against the EPA regulations  in the United States
Court of  Appeals for  the District  of Columbia  Circuit. The  challenges  both
allege  that the regulations are inconsistent with the statutory requirements of
CERCLA and, therefore, should be invalidated. The challenges were filed on  July
28,  1992 and are still pending.) If a lender is or becomes liable, it can bring
an action for contribution against any other 'responsible parties', including  a
previous  owner or  operator, who  created the  environmental hazard,  but those
persons or  entities may  be bankrupt  or otherwise  judgment proof.  The  costs
associated  with environmental  clean-up may  be substantial.  It is conceivable
that such remedial costs  arising from the circumstances  set forth above  would
become a liability of the Trust Fund and occasion a loss to Certificateholders.
 
     Except  as otherwise specified in  the applicable Prospectus Supplement, at
the time the Mortgage  Loans were originated, no  environmental assessment or  a
very limited environmental assessment of the Mortgage Properties was conducted.
 
DUE-ON-SALE CLAUSES
 
     Unless  otherwise  provided  in  the  related  Prospectus  Supplement, each
conventional  Mortgage  Loan  will  contain  a  due-on-sale  clause  which  will
generally  provide that if the mortgagor  or obligor sells, transfers or conveys
the Mortgaged Property, the loan may be accelerated by the mortgagee. In  recent
years,   court  decisions  and  legislative   actions  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 to loans secured by an owner-occupied
residence, the Garn-St Germain Act sets forth nine specific instances in which a
mortgagee covered by the Garn-St Germain Act may not exercise its rights under a
due-on-sale clause, notwithstanding the fact that a transfer of the property may
have  occurred.  The inability  to enforce  a due-on-sale  clause may  result in
transfer of the related  Mortgaged Property to  an uncreditworthy person,  which
could  increase the likelihood of default or may result in a mortgage bearing an
interest rate below the current market rate  being assumed by a new home  buyer,
which  may  affect the  average life  of the  Mortgage Loans  and the  number of
Mortgage Loans which may extend to maturity.
 
PREPAYMENT CHARGES
 
     Under certain state  laws, prepayment charges  may not be  imposed after  a
certain  period of time following the origination of mortgage loans with respect
to prepayments on loans secured by liens encumbering owner-occupied  residential
properties. Since many of the Mortgaged Properties will be owner-occupied, it is
anticipated  that prepayment charges may not be  imposed with respect to many of
the Mortgage Loans. The absence of such a restraint on prepayment,  particularly
with  respect to  fixed rate  Mortgage Loans  having higher  Mortgage Rates, may
increase the likelihood of refinancing or  other early retirement of such  loans
or contracts.
 
APPLICABILITY OF USURY LAWS
 
     Title  V of the  Depository Institutions Deregulation  and Monetary Control
Act of  1980, enacted  in March  1980  ('Title V'),  provides that  state  usury
limitations shall not apply to certain types of residential first mortgage loans
originated  by  certain  lenders after  March  31,  1980. The  Office  of Thrift
Supervision, as successor to the Federal Home Loan Bank Board, is authorized  to
issue   rules  and   regulations  and   to  publish   interpretations  governing
implementation of  Title  V.  The  statute authorized  the  states  to  reimpose
interest rate
 
                                       53
 

<PAGE>
<PAGE>

limits  by adopting,  before April  1, 1983,  a law  or constitutional provision
which expressly rejects  an application of  the federal law.  In addition,  even
where  Title V is not so rejected, any state is authorized by the law to adopt a
provision limiting discount points or other charges on mortgage loans covered by
Title V.  Certain states  have taken  action to  reimpose interest  rate  limits
and/or to limit discount points or other charges.
 
SOLDIERS' AND SAILORS' CIVIL RELIEF ACT
 
     Generally,  under the terms of the  Soldiers' and Sailors' Civil Relief Act
of 1940, as amended (the 'Relief  Act'), a borrower who enters military  service
after the origination of such borrower's mortgage loan (including a borrower who
is  a member of the  National Guard or is  in reserve status at  the time of the
origination of the mortgage loan and is later called to active duty) may not  be
charged interest above an annual rate of 6% during the period of such borrower's
active  duty status,  unless a  court orders  otherwise upon  application of the
lender. It is possible that such interest rate limitation could have an  effect,
for  an indeterminate period of  time, on the ability  of the Master Servicer to
collect full  amounts of  interest  on certain  of  the Mortgage  Loans.  Unless
otherwise  provided in  the applicable  Prospectus Supplement,  any shortfall in
interest collections  resulting from  the application  of the  Relief Act  could
result in losses to the holders of the Certificates. In addition, the Relief Act
imposes  limitations which  would impair the  ability of the  Master Servicer to
foreclose on an affected  Mortgage Loan during the  borrower's period of  active
duty  status. Thus, in  the event that  such a Mortgage  Loan goes into default,
there may be delays and losses occasioned  by the inability to realize upon  the
Mortgaged Property in a timely fashion.

                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     The  following  summary  of  the anticipated  material  federal  income tax
consequences of the purchase, ownership and disposition of Certificates is based
on the advice of Brown & Wood,  counsel to the Depositor. This summary is  based
on  laws,  regulations,  including  the  REMIC  regulations  promulgated  by the
Treasury Department on December 23, 1992 and generally effective for REMICs with
start-up dates on or after November 12, 1991 (the 'REMIC Regulations'),  rulings
and  decisions now in effect  or (with respect to  regulations) proposed, all of
which are subject to change either prospectively or retroactively. This  summary
does  not  address  the federal  income  tax  consequences of  an  investment in
Certificates applicable  to all  categories  of investors,  some of  which  (for
example,  banks  and  insurance  companies) may  be  subject  to  special rules.
Prospective investors should consult their  tax advisors regarding the  federal,
state,  local and any other tax consequences  to them of the purchase, ownership
and disposition of Certificates.
 
GENERAL
 
     The  federal  income  tax  consequences  to  Certificateholders  will  vary
depending  on whether an election is made to  treat the Trust Fund relating to a
particular Series of  Certificates as  a REMIC  under the  Code. The  Prospectus
Supplement for each Series of Certificates will specify whether a REMIC election
will be made.
 
NON-REMIC CERTIFICATES
 
     If a REMIC election is not made, Brown & Wood will deliver its opinion that
the Trust Fund will not be classified as an association taxable as a corporation
and  that  each such  Trust Fund  will be  classified as  a grantor  trust under
subpart E, Part  I of subchapter  J of the  Internal Revenue Code  of 1986  (the
'Code'  referred to in  this section unless otherwise  indicated). In this case,
owners of Certificates will be treated for federal income tax purposes as owners
of a portion of the Trust Fund's assets as described below.
 
A. SINGLE CLASS OF CERTIFICATES
 
     Characterization.   The  Trust  Fund  may be  created  with  one  class  of
Certificates.  In this case, each Certificateholder will be treated as the owner
of a pro rata undivided interest in  the interest and principal portions of  the
Trust  Fund represented by the Certificates and will be considered the equitable
owner of a  pro rata undivided  interest in each  of the Mortgage  Loans in  the
Pool.  Any amounts received by  a Certificateholder in lieu  of amounts due with
respect to any  Mortgage Loans because  of a default  or delinquency in  payment
will  be treated for federal income tax purposes as having the same character as
the payments they replace.
 
     Each Certificateholder will be required to report on its federal income tax
return in accordance with such Certificateholder's method of accounting its  pro
rata  share  of the  entire income  from the  Mortgage Loans  in the  Trust Fund
represented  by  Certificates,  including  interest,  original  issue   discount
('OID'),  if any, prepayment fees, assumption  fees, any gain recognized upon an
assumption and late payment charges received by the Master Servicer. Under  Code
Sections  162 or 212 each  Certificateholder will be entitled  to deduct its pro
rata share  of  servicing  fees,  prepayment fees,  assumption  fees,  any  loss
recognized  upon an assumption  and late payment charges  retained by the Master
Servicer, provided that  such amounts are  reasonable compensation for  services
rendered  to the Trust Fund. Certificateholders that are individuals, estates or
trusts will be entitled  to deduct their  share of expenses  only to the  extent
such  expenses plus such taxpayer's  other miscellaneous itemized deductions (as
defined in  the  Code)  exceed two  percent  of  its adjusted  gross  income.  A
Certificateholder using the cash method of accounting must take into account its
pro  rata share of income and deductions as and when collected by or paid to the
Master Servicer. A Certificateholder using an accrual method of accounting  must
take into account its pro rata share of income and deductions as they become due
(or  received if received prior to when due)  or are paid (or accrued if accrued
prior to payment)  to the Master  Servicer. If  the servicing fees  paid to  the
Master  Servicer  are deemed  to exceed  reasonable servicing  compensation, the
amount of such excess could be  considered as an ownership interest retained  by
the  Master Servicer  (or any  person to whom  the Master  Servicer assigned for
value all or  a portion  of the  servicing fees) in  a portion  of the  interest
payments  on the Mortgage Loans. The Mortgage Loans would then be subject to the
'coupon stripping' rules of the Code discussed below.
 
     Unless otherwise specified in the related Prospectus Supplement, as to each
Series of Certificates Brown & Wood will have advised the Depositor that:
 
          (i) a Certificate owned by a 'domestic building and loan  association'
     within  the meaning of Code  Section 7701(a)(19) representing principal and
     interest   payments   on   Mortgage    Loans   will   be   considered    to
 
                                       55

     represent 'loans . . . secured by an interest in real property which is . .
     .    residential   property'   within   the   meaning   of   Code   Section
     7701(a)(19)(C)(v), to the  extent that  the Mortgage  Loans represented  by
     that Certificate are of a type described in such Code section;
 
          (ii)  a Certificate owned by a financial institution described in Code
     Section 593(a)  representing principal  and interest  payments on  Mortgage
     Loans  will  be considered  to represent  'qualifying real  property loans'
     within the  meaning of  Code Section  593(d) and  the Treasury  regulations
     under  Code Section 593, to the  extent that the Mortgage Loans represented
     by that Certificate are of a type described in such Code section;
 
          (iii)  a  Certificate  owned  by   a  real  estate  investment   trust
     representing  an interest in Mortgage Loans will be considered to represent
     'real estate assets' within the  meaning of Code Section 856(c)(5)(A),  and
     interest  income  on the  Mortgage Loans  will  be considered  'interest on
     obligations secured by mortgages  on real property'  within the meaning  of
     Code   Section  856(c)(3)(B),  to  the   extent  that  the  Mortgage  Loans
     represented by  that Certificate  are  of a  type  described in  such  Code
     section; and
 
          (iv)  a Certificate owned by a REMIC will represent an 'obligation . .
     . which is principally secured, directly  or indirectly, by an interest  in
     real property' within the meaning of Code Section 860G(a)(3).
 
     Buydown  Loans.   The assets constituting  certain Trust  Funds may include
Buydown Loans.  The characterization  of any  investment in  Buydown Loans  will
depend  upon the  precise terms  of the  related buydown  agreement, but  to the
extent that such Buydown Loans  are secured in part by  a bank account or  other
personal property, they may not be treated in their entirety as assets described
in  the  foregoing  sections  of  the Code.  There  are  no  directly applicable
precedents  with  respect   to  the   federal  income  tax   treatment  or   the
characterization of investments in Buydown Loans. Accordingly,
Certificateholders  should consult  their own tax  advisors with  respect to the
characterization of investments  in Certificates representing  an interest in  a
Trust Fund that includes Buydown Loans.
 
     Premium.  The price paid for a Certificate by a holder will be allocated to
such  holder's undivided interest  in each Mortgage Loan  based on each Mortgage
Loan's relative fair market value, so  that such holder's undivided interest  in
each  Mortgage  Loan  will have  its  own  tax basis.  A  Certificateholder that
acquires an  interest in  Mortgage Loans  at  a premium  may elect,  under  Code
section 171, to amortize such premium under a constant interest method, provided
that  the underlying  mortgage loans  with respect  to such  Mortgage Loans were
originated after  September  27,  1985.  Premium  allocable  to  mortgage  loans
originated  on  or  before September  27,  1985  should be  allocated  among the
principal payments on such mortgage loans  and allowed as an ordinary  deduction
as  principal payments are made. Amortizable bond  premium will be treated as an
offset to interest income  on such Certificate. The  basis for such  Certificate
will  be reduced  to the  extent that amortizable  premium is  applied to offset
interest payments. It is  not clear whether  a reasonable prepayment  assumption
should be used in computing amortization of premium allowable under Code Section
171.
 
     If  a premium is not subject  to amortization using a reasonable prepayment
assumption, the holder of a Certificate acquired at a premium should recognize a
loss if  a Mortgage  Loan (or  an underlying  mortgage loan  with respect  to  a
Mortgage  Loan) prepays in full, equal to  the difference between the portion of
the prepaid principal amount of such Mortgage Loan (or underlying mortgage loan)
that is allocable to the  Certificate and the portion  of the adjusted basis  of
the  Certificate that is allocable to such Mortgage Loan (or underlying mortgage
loan). If a reasonable prepayment assumption  is used to amortize such  premium,
it  appears that such a loss would be  available, if at all, only if prepayments
have occurred at a rate faster  than the reasonable assumed prepayment rate.  It
is  not  clear  whether  any  other adjustments  would  be  required  to reflect
differences  between  an  assumed  prepayment  rate  and  the  actual  rate   of
prepayments.
 
     Original  Issue Discount.   The  Internal Revenue  Service (the  'IRS') has
stated in published rulings  that, in circumstances  similar to those  described
herein,  the special  rules of  the Code  relating to  'original issue discount'
(currently Code Sections  1271 through 1273  and 1275) will  be applicable to  a
Certificateholder's  interest  in those  Mortgage  Loans meeting  the conditions
necessary for  these  sections to  apply.  OID  generally must  be  reported  as
ordinary  gross  income as  it  accrues under  a  constant interest  method. See
' -- Multiple Classes of Certificates -- Certificates Representing Interests  in
Loans Other Than ARM Loans' below.
 
     Market  Discount.  A Certificateholder  that acquires an undivided interest
in Mortgage Loans may be subject to  the market discount rules of Code  Sections
1276  through 1278  to the extent  an undivided  interest in a  Mortgage Loan is
considered to have been purchased at a 'market discount.' Generally, the  amount
of market discount is equal to the excess of the portion of the principal amount
of such Mortgage Loan allocable to such
 
                                       56
 

<PAGE>
<PAGE>

holder's  undivided  interest over  such holder's  tax  basis in  such interest.
Market discount with respect to a Certificate  will be considered to be zero  if
the  amount allocable to the Certificate is less than 0.25% of the Certificate's
stated redemption price at maturity multiplied by the weighted average  maturity
remaining  after  the date  of purchase.  Treasury regulations  implementing the
market discount  rules have  not yet  been issued;  therefore, investors  should
consult  their own tax advisors regarding the application of these rules and the
advisability of making  any of the  elections allowed under  Code Sections  1276
through 1278.
 
     The  Code provides that any principal  payment (whether a scheduled payment
or a prepayment) or any gain on  disposition of a market discount bond  acquired
by  the taxpayer after October 22, 1986,  shall be treated as ordinary income to
the extent that it does  not exceed the accrued market  discount at the time  of
such  payment. The amount of accrued market discount for purposes of determining
the tax treatment of subsequent principal payments or dispositions of the market
discount bond is to be reduced by the amount so treated as ordinary income.
 
     The Code also grants the Treasury Department authority to issue regulations
providing for the computation  of accrued market  discount on debt  instruments,
the  principal of which  is payable in  more than one  installment. Although the
Treasury Department  has not  yet  issued regulations,  rules described  in  the
relevant  legislative history describes how market discount should be accrued on
such instruments. According to such legislative history, the holder of a  market
discount  bond may  elect to  accrue market  discount either  on the  basis of a
constant interest  rate or  according to  one  of the  following methods.  If  a
Certificate  is  issued with  OID, the  amount of  market discount  that accrues
during any  accrual period  would  be equal  to the  product  of (i)  the  total
remaining market discount and (ii) a fraction, the numerator of which is the OID
accruing  during the period and the denominator  of which is the total remaining
OID at the beginning of the accrual period. For Certificates issued without OID,
the amount of  market discount  that accrues  during a  period is  equal to  the
product  of (i)  the total  remaining market discount  and (ii)  a fraction, the
numerator of which  is the  amount of stated  interest paid  during the  accrual
period  and the  denominator of  which is  the total  amount of  stated interest
remaining to be paid  at the beginning  of the accrual  period. For purposes  of
calculating  market  discount under  any of  the  above methods  in the  case of
instruments that  provide for  payments that  may be  accelerated by  reason  of
prepayments  of  other  obligations  (which  technically  does  not  include the
Certificates)  securing  such  instruments,   the  same  prepayment   assumption
applicable to calculating the accrual of OID will apply. Because the regulations
described  above have not been  issued, it is impossible  to predict what effect
those regulations might have on the tax treatment of a Certificate purchased  at
a discount or premium in the secondary market.
 
     A  holder  who acquired  a Certificate  at  a market  discount also  may be
required to defer, until  the maturity date of  such Certificate or its  earlier
disposition  in a taxable transaction, the deduction  of a portion of the amount
of interest  that  the  holder  paid  or accrued  during  the  taxable  year  on
indebtedness  incurred or  maintained to purchase  or carry  such Certificate in
excess of the aggregate  amount of interest (including  OID) includible in  such
holder's gross income for the taxable year with respect to such Certificate. The
amount  of such net interest  expense deferred in a  taxable year may not exceed
the amount of market discount accrued on the Certificate for the days during the
taxable year on which the holder held the Certificate and, in general, would  be
deductible  when such market discount is includible in income. The amount of any
remaining deferred deduction is to be taken into account in the taxable year  in
which the Certificate matures or is disposed of in a taxable transaction. In the
case  of a disposition  in which gain or  loss is not recognized  in whole or in
part, any remaining  deferred deduction will  be allowed to  the extent of  gain
recognized  on  the  disposition.  This  deferral rule  does  not  apply  if the
Certificateholder elects to include such market discount in income currently  as
it accrues on all market discount obligations acquired by such Certificateholder
in that taxable year or thereafter.
 
     Election  to  Treat  All Interest  as  OID.  The OID  Regulations  permit a
Certificateholder to  elect  to  accrue all  interest,  discount  (including  de
minimis  market or original  issue discount) and premium  in income as interest,
based on a constant yield method for Certificates acquired on or after April  4,
1994.  If such an  election were to be  made with respect  to a Certificate with
market discount, the Certificateholder would be deemed to have made an  election
to  include in income currently  market discount with respect  to all other debt
instruments having market discount  that such Certificateholder acquires  during
the  year of  the election  or thereafter.  Similarly, a  Certificateholder that
makes this election  for a Certificate  that is  acquired at a  premium will  be
deemed  to have made  an election to  amortize bond premium  with respect to all
debt instruments  having amortizable  bond premium  that such  Certificateholder
owns  or acquires. See ' -- Single Class of Certificates -- Premium' herein. The
election to accrue  interest, discount and  premium on a  constant yield  method
with  respect to  a Certificate  cannot be  revoked without  the consent  of the
Internal Revenue Service ('IRS').

B. MULTIPLE CLASSES OF CERTIFICATES
 
     1. Stripped Bonds and Stripped Coupons
 
     Pursuant to Code Section 1286, the separation of ownership of the right  to
receive  some or all of the interest payments on an obligation from ownership of
the right  to receive  some or  all of  the principal  payments results  in  the
creation  of 'stripped bonds'  with respect to  principal payments and 'stripped
coupons' with respect to interest payments.  For purposes of Code Sections  1271
through  1288, Code Section 1286 treats a  stripped bond or a stripped coupon as
an obligation issued on the  date that such stripped  interest is created. If  a
Trust   Fund  is  created  with  two  classes  of  Certificates,  one  class  of
Certificates may represent  the right  to principal and  interest, or  principal
only,   on  all  or  a  portion  of  the  Mortgage  Loans  (the  'Stripped  Bond
Certificates'), while the second class  of Certificates may represent the  right
to  some  or  all  of  the  interest  on  such  portion  (the  'Stripped  Coupon
Certificates').
 
     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 Mortgage Loan  principal
balance)  or  the Certificates  are initially  sold with  a de  minimis discount
(which amount may  be calculated  without a prepayment  assumption), any  non-de
minimis  discount arising from a subsequent  transfer of the Certificates should
be treated  as market  discount.  The IRS  appears  to require  that  reasonable
servicing  fees be calculated on  a Mortgage Loan by  Mortgage Loan basis, which
could result in some Mortgage Loans being treated as having more than 100  basis
points  of interest stripped off. See ' -- Non-REMIC Certificates' and 'Multiple
Classes of Senior Certificates -- Stripped Bonds and Stripped Coupons' herein.
 
     Although not entirely clear, a  Stripped Bond Certificate generally  should
be  treated as an interest in Mortgage  Loans issued on the day such Certificate
is purchased for purposes of calculating any OID. Generally, if the discount  on
a  Mortgage Loan is larger than a  de minimis amount (as calculated for purposes
of the OID rules) a purchaser of  such a Certificate will be required to  accrue
the  discount under the OID rules of  the Code. See ' -- Non-REMIC Certificates'
and '  -- Single  Class  of Certificates  --  Original Issue  Discount'  herein.
However,  a purchaser of a Stripped Bond Certificate will be required to account
for any discount on  the Mortgage Loans  as market discount  rather than OID  if
either  (i) the amount  of OID with respect  to the Mortgage  Loan is treated as
zero under the OID de minimis rule when the Certificate was stripped or (ii)  no
more  than 100 basis points (including any amount of servicing fees in excess of
reasonable servicing fees) is stripped off of the Trust Fund's Mortgage Loans.
 
     The precise tax treatment of Stripped Coupon Certificates is  substantially
uncertain.  The Code could be read literally to require that OID computations be
made for each payment from each Mortgage Loan. However, based on the recent  IRS
guidance,  it  appears  that all  payments  from  a Mortgage  Loan  underlying a
Stripped Coupon Certificate should be treated as a single installment obligation
subject to the  OID rules of  the Code, in  which case, all  payments from  such
Mortgage  Loan would be included in  the Mortgage Loan's stated redemption price
at maturity for purposes of calculating income on such certificate under the OID
rules of the Code.
 
     It is unclear under what circumstances, if any, the prepayment of  Mortgage
Loans  will give  rise to a  loss to the  holder of a  Stripped Bond Certificate
purchased at a premium or a Stripped Coupon Certificate. If such Certificate  is
treated  as a  single instrument (rather  than an interest  in discrete mortgage
loans) and the effect  of prepayments is taken  into account in computing  yield
with respect to such Certificate, it appears that no loss will be available as a
result  of any particular  prepayment unless prepayments occur  at a rate faster
than the assumed prepayment rate. However, if such Certificate is treated as  an
interest  in discrete  Mortgage Loans, or  if no prepayment  assumption is used,
then when a Mortgage Loan is prepaid,  the holder of such Certificate should  be
able to recognize a loss equal to the portion of the unrecovered premium of such
Certificate that is allocable to such Mortgage Loan.
 
     Holders  of Stripped Bond Certificates and Stripped Coupon Certificates are
urged to consult with their own  tax advisors regarding the proper treatment  of
these Certificates for federal income tax purposes.
 
     2. Certificates Representing Interests in Loans Other Than ARM Loans
 
     The  original issue discount rules of  Code Sections 1271 through 1275 will
be applicable to a  Certificateholder's interest in those  Mortgage Loans as  to
which  the  conditions for  the  application of  those  sections are  met. Rules
regarding periodic inclusion of original issue discount in income are applicable
to mortgages  of  corporations  originated  after May  27,  1969,  mortgages  of
noncorporate mortgagors (other than
 
                                       58
 

<PAGE>
<PAGE>

individuals)  originated  after  July  1,  1982,  and  mortgages  of individuals
originated after March 2, 1984. Under  the OID Regulations, such original  issue
discount could arise by the charging of points by the originator of the mortgage
in  an  amount greater  than  the statutory  de  minimis exception,  including a
payment of points that is currently deductible by the borrower under  applicable
Code  provisions, or  under certain circumstances,  by the  presence of 'teaser'
rates (i.e., the initial rates on  the Mortgage Loans are lower than  subsequent
rates on the Mortgage Loans) on the Mortgage Loans.
 
     OID on each Certificate must be included in the owner's ordinary income for
federal  income  tax  purposes as  it  accrues,  in accordance  with  a constant
interest method that takes into account the compounding of interest, in  advance
of  receipt of the cash attributable to  such income. The amount of OID required
to be  included in  an owner's  income in  any taxable  year with  respect to  a
Certificate representing an interest in Mortgage Loans other than Mortgage Loans
with  interest  rates  that adjust  periodically  ('ARM Loans')  likely  will be
computed as described below under ' -- Accrual of Original Issue Discount.'  The
following  discussion is based in part on Treasury regulations issued on January
27, 1994, under Code Sections 1271 through 1273 and 1275 (the 'OID Regulations')
and in part on the  provisions of the Tax Reform  Act of 1986 (the '1986  Act').
The  OID Regulations generally  are effective for debt  instruments issued on or
after April 4, 1994, but  may be relied upon as  authority with respect to  debt
instruments  issued after  December 21,  1992. Alternatively,  proposed Treasury
regulations issued  December 21,  1992  may be  treated  as authority  for  debt
instruments  issued after  December 21,  1992 and  prior to  April 4,  1994, and
proposed Treasury  regulations  issued  in  1986 and  1991  may  be  treated  as
authority  for instruments  issued before December  21, 1992.  In applying these
dates, the issued date of the Mortgage Loans should be used, or, in the case  of
Stripped  Bond  Certificates  or  Stripped Coupon  Certificates,  the  date such
Certificates are acquired. The holder of a Certificate should be aware, however,
that neither the  proposed OID  Regulations nor the  OID Regulations  adequately
address certain issues relevant to prepayable securities.
 
     Under  the Code,  the Mortgage  Loans underlying  the Certificates  will be
treated as having been issued on the date the were originated with an amount  of
OID  equal to  the excess  of such  Mortgage Loan's  stated redemption  price at
maturity over its issue price. The issue  price of a Mortgage Loan is  generally
the  amount lent to  the mortgagee, which  may be adjusted  to take into account
certain loan origination  fees. The  stated redemption  price at  maturity of  a
Mortgage  Loan is the sum of all payments to be made on such Mortgage Loan other
than payments  that  are treated  as  qualified stated  interest  payments.  The
accrual  of this OID,  as described below  under ' --  Accrual of Original Issue
Discount,'  will,  unless   otherwise  specified  in   the  related   Prospectus
Supplement,   utilize  the  original  yield  to  maturity  of  the  Certificates
calculated based on a reasonable assumed prepayment rate for the mortgage  loans
underlying  the Certificates (the  'Prepayment Assumption'), and  will take into
account  events  that  occur  during  the  calculation  period.  The  Prepayment
Assumption  will be determined in the manner prescribed by regulations that have
not yet been issued. The legislative  history of the 1986 Act (the  'Legislative
History')  provides,  however,  that  the  regulations  will  require  that  the
Prepayment Assumption be the prepayment  assumption that is used in  determining
the  offering  price of  such Certificate.  No representation  is made  that any
Certificate will prepay at the Prepayment  Assumption or at any other rate.  The
prepayment  assumption  contained in  the Code  literally  only applies  to debt
instruments collateralized  by  other  debt  instruments  that  are  subject  to
prepayment rather than direct ownership interests in such debt instruments, such
as  the  Certificates  represent.  However, no  other  legal  authority provides
guidance with regard to the proper  method for accruing OID on obligations  that
are  subject to  prepayment, and, until  further guidance is  issued, the Master
Servicer intends to calculate and report OID under the method described below.
 
     Accrual of Original Issue Discount.  Generally, the owner of a  Certificate
must  include in gross income the sum of the 'daily portions,' as defined below,
of the OID on such Certificate for  each day on which it owns such  Certificate,
including  the date of  purchase but excluding  the date of  disposition. In the
case of  an original  owner, the  daily portions  of OID  with respect  to  each
component generally will be determined as set forth under the OID Regulations. A
calculation  will be made by the Master  Servicer or such other entity specified
in the related Prospectus Supplement of  the portion of OID that accrues  during
each  successive  monthly accrual  period (or  shorter period  from the  date of
original issue) that ends on the day in the calendar year corresponding to  each
of  the Distribution Dates  on the Certificates  (or the day  prior to each such
date). This will  be done, in  the case of  each full month  accrual period,  by
adding  (i) the present  value at the  end of the  accrual period (determined by
using as a  discount factor  the original yield  to maturity  of the  respective
component  under  the Prepayment  Assumption) of  all  remaining payments  to be
received under the Prepayment  Assumption on the  respective component and  (ii)
any  payments received  during such  accrual period,  and subtracting  from that
total
 
                                       59
 

<PAGE>
<PAGE>

the 'adjusted issue price' of the respective component at the beginning of  such
accrual  period. The adjusted issue  price of a Certificate  at the beginning of
the first accrual  period is  its issue  price; the  adjusted issue  price of  a
Certificate  at the  beginning of  a subsequent  accrual period  is the adjusted
issue price at the  beginning of the immediately  preceding accrual period  plus
the  amount of OID allocable to that accrual period reduced by the amount of any
payment made at  the end  of or  during that  accrual period.  The OID  accruing
during  such accrual period  will then be divided  by the number  of days in the
period to determine the daily  portion of OID for each  day in the period.  With
respect to an initial accrual period shorter than a full monthly accrual period,
the  daily  portions  of OID  must  be  determined according  to  an appropriate
allocation under any reasonable method.
 
     Original issue discount generally must be reported as ordinary gross income
as it  accrues under  a constant  interest method  that takes  into account  the
compounding  of interest as  it accrues rather than  when received. However, the
amount of original issue  discount includible in  the income of  a holder of  an
obligation is reduced when the obligation is acquired after its initial issuance
at  a price greater than the sum of  the original issue price and the previously
accrued original issue discount, less prior payments of principal.  Accordingly,
if  such Mortgage Loans acquired by a Certificateholder are purchased at a price
equal to the  then unpaid principal  amount of such  Mortgage Loan, no  original
issue  discount attributable to  the difference between the  issue price and the
original principal amount of  such Mortgage Loan (e.g.,  due to points) will  be
includible  by such holder. Other original  issue discount on the Mortgage Loans
(e.g., that arising from a 'teaser' rate) would still need to be accrued.
 
     3. Certificates Representing Interests in ARM Loans
 
     The OID Regulations do  not address the treatment  of instruments, such  as
the  Certificates, which represent interests in ARM Loans. Additionally, the IRS
has not issued guidance under the Code's coupon stripping rules with respect  to
such  instruments. In  the absence  of any  authority, the  Master Servicer will
report  OID  on   Certificates  attributable   to  ARM   Loans  ('Stripped   ARM
Obligations')  to holders in a  manner it believes is  consistent with the rules
described above under the  heading ' --  Certificates Representing Interests  in
Loans  Other  Than  ARM  Loans'  and  with  the  OID  Regulations.  In  general,
application of these  rules may require  inclusion of income  on a Stripped  ARM
Obligation  in  advance of  the  receipt of  cash  attributable to  such income.
Further, the addition of  interest deferred by  reason of negative  amortization
('Deferred  Interest') to the principal  balance of an ARM  Loan may require the
inclusion of such amount in the income of the Certificateholder when such amount
accrues. Furthermore, the  addition of  Deferred Interest  to the  Certificate's
principal  balance  will result  in  additional income  (including  possibly OID
income) to the Certificateholder over the remaining life of such Certificates.
 
     Because the treatment of Stripped  ARM Obligations is uncertain,  investors
are  urged to consult their tax advisors regarding how income will be includible
with respect to such Certificates.
 
C. SALE OR EXCHANGE OF A CERTIFICATE
 
     Sale or exchange of a Certificate prior to its maturity will result in gain
or loss equal to  the difference, if  any, between the  amount received and  the
owner's  adjusted basis in  the Certificate. Such  adjusted basis generally will
equal the seller's  purchase price  for the  Certificate, increased  by the  OID
included  in  the seller's  gross income  with respect  to the  Certificate, and
reduced by  principal payments  on the  Certificate previously  received by  the
seller.  Such gain or loss will be capital gain  or loss to an owner for which a
Certificate is a 'capital  asset' within the meaning  of Code Section 1221,  and
will  be long-term or  short-term depending on whether  the Certificate has been
owned for the  long-term capital gain  holding period (currently  more than  one
year).
 
     The  Certificates will be 'evidences of indebtedness' within the meaning of
Code Section 582(c)(1),  so that  gain or  loss recognized  from the  sale of  a
Certificate by a bank or a thrift institution to which such section applies will
be ordinary income or loss.
 
D. NON-U.S. PERSONS
 
     Generally,  to  the  extent  that  a  Certificate  evidences  ownership  in
underlying Mortgage Loans that were issued on or before July 18, 1984,  interest
or  OID paid by the  person required to withhold tax  under Code Section 1441 or
1442 to (i) an  owner that is  not a U.S.  Person (as defined  below) or (ii)  a
Certificateholder  holding on behalf of an owner  that is not a U.S. Person will
be subject to federal income tax, collected by withholding, at a rate of 30%  or
such  lower rate as  may be provided  for interest by  an applicable tax treaty.
Accrued OID  recognized  by  the  owner  on the  sale  or  exchange  of  such  a
Certificate also will be subject to
 
                                       60
 

<PAGE>
<PAGE>

federal  income tax  at the  same rate.  Generally, such  payments would  not be
subject to withholding to the extent  that a Certificate evidences ownership  in
Mortgage  Loans  issued  after  July  18,  1984,  by  natural  persons  if  such
Certificateholder complies with  certain identification requirements  (including
delivery  of a  statement, signed  by the  Certificateholder under  penalties of
perjury, certifying  that  such  Certificateholder  is not  a  U.S.  Person  and
providing   the  name   and  address  of   such  Certificateholder).  Additional
restrictions apply to Mortgage Loans where the mortgagor is not a natural person
in order to qualify for the exemption from withholding.
 
     As used herein, a 'U.S. Person' means  a citizen or resident of the  United
States,  a corporation or  a partnership organized  in or under  the laws of the
United States or any  political subdivision thereof or  an estate or trust,  the
income  of which from sources  outside the United States  is includible in gross
income for federal  income tax purposes  regardless of its  connection with  the
conduct of a trade or business within the United States.
 
E. INFORMATION REPORTING AND BACKUP WITHHOLDING
 
     The  Master Servicer  will furnish or  make available,  within a reasonable
time  after  the  end  of  each  calendar  year,  to  each  person  who  was   a
Certificateholder  at  any time  during such  year, such  information as  may be
deemed necessary or  desirable to assist  Certificateholders in preparing  their
federal  income  tax returns,  or  to enable  holders  to make  such information
available to  beneficial  owners  or financial  intermediaries  that  hold  such
Certificates as nominees on behalf of beneficial owners. If a holder, beneficial
owner,  financial intermediary or  other recipient of  a payment on  behalf of a
beneficial owner fails to supply  a certified taxpayer identification number  or
if  the Secretary of the  Treasury determines that such  person has not reported
all interest and dividend income required to be shown on its federal income  tax
return, 31% backup withholding may be required with respect to any payments. Any
amounts  deducted  and withheld  from  a distribution  to  a recipient  would be
allowed as a credit against such recipient's federal income tax liability.
 
REMIC CERTIFICATES
 
     The Trust Fund relating to a Series of Certificates may elect to be treated
as a REMIC. Qualification  as a REMIC requires  ongoing compliance with  certain
conditions.  Although a  REMIC is  not generally  subject to  federal income tax
(see, however  ' --  Residual Certificates'  and '  -- Prohibited  Transactions'
below),  if a Trust Fund with respect to which a REMIC election is made fails to
comply with one or more of the ongoing requirements of the Code for REMIC status
during any taxable  year, including  the implementation of  restrictions on  the
purchase  and transfer of the  residual interests in a  REMIC as described below
under 'Residual Certificates,' the Code provides  that a Trust Fund will not  be
treated  as a REMIC for such year and thereafter. In that event, such entity may
be taxable as a separate corporation,  and the related Certificates (the  'REMIC
Certificates')  may  not  be accorded  the  status  or given  the  tax treatment
described below.  While the  Code authorizes  the Treasury  Department to  issue
regulations  providing relief in the event  of an inadvertent termination of the
status of a trust  fund as a  REMIC, no such regulations  have been issued.  Any
such  relief, moreover, may be accompanied  by sanctions, such as the imposition
of a corporate tax on all or a  portion of the REMIC's income for the period  in
which  the requirements for such status are  not satisfied. With respect to each
Trust Fund  that elects  REMIC status,  Brown &  Wood will  deliver its  opinion
generally  to the effect  that, under then existing  law and assuming compliance
with all provisions of the related Agreement, such Trust Fund will qualify as  a
REMIC,  and the related Certificates will  be considered to be regular interests
('Regular Certificates') or residual interests ('Residual Certificates') in  the
REMIC.  The related Prospectus  Supplement for each  Series of Certificates will
indicate whether the Trust Fund will make  a REMIC election and whether a  class
of Certificates will be treated as a regular or residual interest in the REMIC.
 
     In  general, with respect to each Series  of Certificates for which a REMIC
election is  made, (i)  Certificates held  by a  thrift institution  taxed as  a
'mutual savings bank' or 'domestic building and loan association' will represent
interests in 'qualifying real property loans' within the meaning of Code Section
593(d)(1);  (ii) Certificates held by a  thrift institution taxed as a 'domestic
building and loan association' will constitute assets described in Code  Section
7701(a)(19)(C);  (iii) Certificates held by a  real estate investment trust will
constitute 'real estate assets' within the meaning of Code Section 856(c)(5)(A);
and (iv) interest on Certificates held by a real estate investment trust will be
considered 'interest  on  obligations secured  by  mortgages on  real  property'
within the meaning of Code Section 856(c)(3)(B). If less than 95% of the REMIC's
assets  are  assets qualifying  under any  of the  foregoing Code  sections, the
Certificates will  be qualifying  assets only  to the  extent that  the  REMIC's
assets  are  qualifying assets.  In addition,  payments  on Mortgage  Loans held
pending distribution on the
 
                                       61
 

<PAGE>
<PAGE>

REMIC Certificates will be considered to  be qualifying real property loans  for
purposes  of Code Section 593(d)(1) and real  estate assets for purposes of Code
Section 856(c).
 
     In some instances the Mortgage Loans may not be treated entirely as  assets
described  in the  foregoing sections.  See, in  this regard,  the discussion of
Buydown Loans  contained in  '  -- Non-REMIC  Certificates  -- Single  Class  of
Certificates'  above. REMIC Certificates held by  a real estate investment trust
will not constitute 'Government Securities'  within the meaning of Code  Section
856(c)(5)(A), and REMIC Certificates held by a regulated investment company will
not  constitute  'Government  Securities'  within the  meaning  of  Code Section
851(b)(4)(A)(ii). REMIC Certificates held by certain financial institutions will
constitute 'evidences  of  indebtedness'  within the  meaning  of  Code  Section
582(c)(1).
 
     A  'qualified  mortgage' for  REMIC purposes  is any  obligation (including
certificates of participation in such an obligation) that is principally secured
by an interest in real  property and that is transferred  to the REMIC within  a
prescribed  time period  in exchange  for regular  or residual  interests in the
REMIC. The REMIC Regulations provide  that manufactured housing or mobile  homes
(not  including  recreational vehicles,  campers or  similar vehicles)  that are
'single family residences'  under Code  Section 25(e)(10) will  qualify as  real
property  without  regard  to  state  law  classifications.  Under  Code Section
25(e)(10), a single family residence includes  any manufactured home that has  a
minimum  of 400 square feet of living space and a minimum width in excess of 102
inches and that is of a kind customarily used at a fixed location.
 
     Tiered REMIC Structures.  For certain Series of Certificates, two  separate
elections  may be made to treat designated portions of the related Trust Fund as
REMICs (respectively, the 'Subsidiary REMIC' and the 'Master REMIC') for federal
income tax purposes. Upon the issuance of any such Series of Certificates, Brown
& Wood, counsel  to the  Depositor, will deliver  its opinion  generally to  the
effect  that, assuming compliance with all  provisions of the related Agreement,
the Master REMIC as well as any  Subsidiary REMIC will each qualify as a  REMIC,
and  the REMIC Certificates issued by the Master REMIC and the Subsidiary REMIC,
respectively, will be considered to  evidence ownership of Regular  Certificates
or  Residual Certificates in the  related REMIC within the  meaning of the REMIC
provisions.
 
     Only REMIC Certificates, other than the residual interest in the Subsidiary
REMIC, issued by  the Master  REMIC will  be offered  hereunder. The  Subsidiary
REMIC  and the Master REMIC will be treated  as one REMIC solely for purposes of
determining whether the REMIC Certificates will be (i) 'qualifying real property
loans' under Section 593(d)  of the Code; (ii)  'real estate assets' within  the
meaning of Section 856(c)(5)(A) of the Code; (iii) 'loans secured by an interest
in real property' under Section 7701(a)(19)(C) of the Code; and (iv) whether the
income on such Certificates is interest described in Section 856(c)(3)(B) of the
Code.
 
A. REGULAR CERTIFICATES
 
     General.     Except  as  otherwise   stated  in  this  discussion,  Regular
Certificates will be treated for federal income tax purposes as debt instruments
issued by the REMIC and not as  ownership interests in the REMIC or its  assets.
Moreover,  holders of Regular Certificates that  otherwise report income under a
cash method of  accounting will  be required to  report income  with respect  to
Regular Certificates under an accrual method.
 
     Original  Issue  Discount and  Premium.   The  Regular Certificates  may be
issued with original issue discount ('OID').  Generally, such OID, if any,  will
equal  the difference  between the  'stated redemption  price at  maturity' of a
Regular Certificate and its 'issue price.' Holders of any class of  Certificates
issued with OID will be required to include such OID in gross income for federal
income tax purposes as it accrues, in accordance with a constant interest method
based  on the compounding  of interest as  it accrues rather  than in accordance
with receipt of the interest payments. The following discussion is based in part
on Treasury regulations  issued on January  27, 1994, under  Code Sections  1271
through  1273 and 1275 (the 'OID Regulations')  and in part on the provisions of
the Tax Reform Act of 1986 (the  '1986 Act'). The OID Regulations generally  are
effective  for debt  instruments issued  on or after  April 4,  1994. Holders of
Regular  Certificates  (the  'Regular  Certificateholders')  should  be   aware,
however,  that  the OID  Regulations do  not  adequately address  certain issues
relevant to prepayable securities, such as the Regular Certificates.
 
     Rules governing OID are  set forth in Code  Sections 1271 through 1273  and
1275.  These  rules  require that  the  amount and  rate  of accrual  of  OID be
calculated based on the Prepayment  Assumption and the anticipated  reinvestment
rate,  if any, relating to  the Regular Certificates and  prescribe a method for
adjusting the  amount and  rate of  accrual of  such discount  where the  actual
prepayment  rate differs  from the  Prepayment Assumption.  Under the  Code, the
Prepayment  Assumption  must   be  determined  in   the  manner  prescribed   by
regulations,
 
                                       62
 

<PAGE>
<PAGE>

which  regulations have not  yet been issued.  The Legislative History provides,
however, that Congress intended the  regulations to require that the  Prepayment
Assumption  be the prepayment assumption that is used in determining the initial
offering price of such Regular Certificates. The Prospectus Supplement for  each
Series of Regular Certificates will specify the Prepayment Assumption to be used
for  the  purpose of  determining  the amount  and rate  of  accrual of  OID. No
representation is  made  that  the  Regular  Certificates  will  prepay  at  the
Prepayment Assumption or at any other rate.
 
     In   general,  each  Regular  Certificate  will  be  treated  as  a  single
installment obligation issued with an amount of  OID equal to the excess of  its
'stated redemption price at maturity' over its 'issue price.' The issue price of
a  Regular  Certificate is  the first  price  at which  a substantial  amount of
Regular Certificates of that class are first sold to the public (excluding  bond
houses,  brokers, underwriters  or wholesalers).  The issue  price of  a Regular
Certificate also includes the  amount paid by  an initial Certificateholder  for
accrued interest that relates to a period prior to the issue date of the Regular
Certificate.  The stated redemption  price at maturity  of a Regular Certificate
includes the original principal amount of the Regular Certificate, but generally
will not  include distributions  of interest  if such  distributions  constitute
'qualified  stated interest.' Qualified stated interest generally means interest
payable at a single fixed rate  or qualified variable rate (as described  below)
provided that such interest payments are unconditionally payable at intervals of
one  year or less during the entire term of the Regular Certificate. Interest is
payable at a single fixed rate only if the rate appropriately takes into account
the length  of  the interval  between  payments. Distributions  of  interest  on
Regular  Certificates with respect  to which Deferred  Interest will accrue will
not constitute qualified  stated interest  payments, and  the stated  redemption
price  at maturity  of such Regular  Certificates includes  all distributions of
interest as well as principal thereon.
 
     Where the interval between the issue  date and the first Distribution  Date
on  a  Regular  Certificate  is  longer  than  the  interval  between subsequent
Distribution Dates, the greater of any original issue discount disregarding  the
rate  in the first period  and any interest foregone  during the first period is
treated as the amount  by which the stated  redemption price of the  Certificate
exceeds its issue price for purposes of the de minimis rule described below. The
OID  Regulations suggest that all  or a portion of the  interest on a long first
period Regular  Certificate that  is  issued with  non-de  minimis OID  will  be
treated  as  OID.  Where the  interval  between  the issue  date  and  the first
Distribution Date on a Regular Certificate is shorter than the interval  between
subsequent  Distribution Dates, interest  due on the  first Distribution Date in
excess of the amount that accrued during the first period would be added to  the
Certificates  stated  redemption price  at maturity.  Regular Certificateholders
should consult their own  tax advisors to determine  the issue price and  stated
redemption  price  at maturity  of a  Regular  Certificate. Additionally,  it is
possible that the IRS could assert that the stated Pass-Through Rate of interest
on the Regular Certificates is not unconditionally payable because late payments
or nonpayments on the Mortgage Loans are not penalized nor are there  reasonable
remedies  in place to compel  payment on such Mortgage  Loans. Such position, if
successful, would require all holders  of Regular Certificates to accrue  income
on such certificates under the OID Regulations.
 
     Under  the de minimis rule, OID on a Regular Certificate will be considered
to be zero  if such OID  is less than  0.25% of the  stated redemption price  at
maturity  of the Regular Certificate multiplied by the weighted average maturity
of the Regular Certificate. For this  purpose, the weighted average maturity  of
the  Regular Certificate  is computed  as the sum  of the  amounts determined by
multiplying the number of  full years (i.e., rounding  down partial years)  from
the  issue date until each distribution  in reduction of stated redemption price
at maturity is scheduled to be made by a fraction, the numerator of which is the
amount of each distribution included in the stated redemption price at  maturity
of the Regular Certificate and the denominator of which is the stated redemption
price  at maturity  of the Regular  Certificate. Although  currently unclear, it
appears that  the  schedule  of  such  distributions  should  be  determined  in
accordance  with  the  Prepayment  Assumption.  The  Prepayment  Assumption with
respect to a Series  of Regular Certificates  will be set  forth in the  related
Prospectus  Supplement. Holders generally must report de minimis OID pro rata as
principal payments are  received, and such  income will be  capital gain if  the
Regular  Certificate is held as a capital asset. However, accrual method holders
may elect  to accrue  all de  minimis OID  as well  as market  discount under  a
constant interest method.
 
     The  Prospectus Supplement  with respect  to a  Trust Fund  may provide for
certain Regular  Certificates to  be issued  at prices  significantly  exceeding
their   principal  amounts  or   based  on  notional   principal  balances  (the
'Super-Premium  Certificates').  The  income  tax  treatment  of  such   Regular
Certificates  is not entirely  certain. For information  reporting purposes, the
Trust Fund intends  to take  the position that  the stated  redemption price  at
 
                                       63
 

<PAGE>
<PAGE>

maturity  of such Regular Certificates is the sum  of all payments to be made on
such Regular Certificates determined under  the Prepayment Assumption, with  the
result  that such Regular Certificates would be issued with OID. The calculation
of income in this manner could result in negative original issue discount (which
delays future accruals  of OID  rather than being  immediately deductible)  when
prepayments  on the Mortgage  Loans exceed those  estimated under the Prepayment
Assumption. The  IRS might  contend, however,  that certain  contingent  payment
rules  contained  in regulations  proposed  on April  8,  1986, with  respect to
original issue discount should apply to such Certificates. Under those rules,  a
Super-Premium Certificate would not be required to report income on the basis of
a  yield based on the Prepayment Assumption,  but rather would use a yield equal
to  the  applicable  Federal  rate  (which  is  an  average  yield  on  Treasury
obligations),   until  the   initial  price  of   the  respective  Super-Premium
Certificate is fully recovered.  The IRS recently proposed  and then withdrew  a
revised   set  of   proposed  contingent  payment   regulations  which  differed
substantially from the contingent  payment regulation proposed  in 1986. If  the
Super-Premium Certificates were treated as contingent payment obligations, it is
unclear  how holders of those Certificates  would report income or recover their
basis. In the alternative, the IRS could assert that the stated redemption price
at maturity of such  Regular Certificates should be  limited to their  principal
amount   (subject  to  the   discussion  below  under   '  --  Accrued  Interest
Certificates'), so  that  such  Regular Certificates  would  be  considered  for
federal  income tax purposes to be issued at  a premium. If such a position were
to   prevail,    the    rules   described    below    under   '    --    Regular
Certificates  -- Premium' would apply. It is  unclear when a loss may be claimed
for any unrecovered basis for a Super-Premium Certificate. It is possible that a
holder of a Super-Premium Certificate may  only claim a loss when its  remaining
basis  exceeds  the  maximum  amount of  future  payments,  assuming  no further
prepayments or  when  the  final  payment  is  received  with  respect  to  such
Super-Premium Certificate.
 
     Under  the REMIC Regulations,  if the issue price  of a Regular Certificate
(other than those based on a notional amount) does not exceed 125% of its actual
principal amount, the interest rate  is not considered disproportionately  high.
Accordingly,  such  Regular Certificate  generally should  not  be treated  as a
Super-Premium Certificate  and the  rules  described below  under '  --  Regular
Certificates -- Premium' should apply. However, it is possible that certificates
issued  at a premium, even if the premium is less than 25% of such Certificate's
actual principal balance,  will be  required to  amortize the  premium under  an
original  issue discount  method or  contingent interest  method even  though no
election under Code section 171 is made to amortize such premium.
 
     Generally, a Regular  Certificateholder must  include in  gross income  the
'daily  portions,' as  determined below,  of the OID  that accrues  on a Regular
Certificate for  each day  a Certificateholder  holds the  Regular  Certificate,
including  the  purchase  date but  excluding  the disposition  date.  The daily
portions of OID are determined  by allocating to each  day in an accrual  period
the  ratable portion of OID allocable to the accrual period. Accrual periods may
be of  any  length  and  may  vary  in length  over  the  term  of  the  Regular
Certificates, provided that each accrual period (i) is not longer than one year,
(ii)  begins or ends on a Distribution Date (except for the first accrual period
which begins on the issue date) and (iii) begins on the day after the  preceding
accrual period ends. This will be done, in the case of each full accrual period,
by (i) adding (a) the present value at the end of the accrual period (determined
by  using as  a discount factor  the original  yield to maturity  of the Regular
Certificates as calculated  under the  Prepayment Assumption)  of all  remaining
payments  to  be  received  on the  Regular  Certificates  under  the Prepayment
Assumption and  (b) any  payments included  in the  stated redemption  price  at
maturity  received during  such accrual period,  and (ii)  subtracting from that
total the adjusted issue price of  the Regular Certificates at the beginning  of
such  accrual period. The adjusted  issue price of a  Regular Certificate at the
beginning of the  first accrual period  is its issue  price; the adjusted  issue
price  of a Regular Certificate at the  beginning of a subsequent accrual period
is the  adjusted issue  price  at the  beginning  of the  immediately  preceding
accrual  period plus  the amount  of OID  allocable to  that accrual  period and
reduced by the amount of  any payment other than  a payment of qualified  stated
interest  made at  the end  of or  during that  accrual period.  The OID accrued
during an accrual  period will  then be  divided by the  number of  days in  the
period to determine the daily portion of OID for each day in the accrual period.
The  calculation of OID under the method  described above will cause the accrual
of OID to either increase or decrease (but never below zero) in a given  accrual
period  to reflect the fact that prepayments are occurring faster or slower than
under the  Prepayment Assumption.  With  respect to  an initial  accrual  period
shorter  than a full accrual period, the daily portions of OID may be determined
according to an appropriate allocation under any reasonable method.
 
     A subsequent  purchaser  of  a  Regular Certificate  issued  with  OID  who
purchases  the  Regular Certificate  at a  cost less  than the  remaining stated
redemption price at maturity  will also be required  to include in gross  income
 
                                       64
 

<PAGE>
<PAGE>

the  sum of the daily portions of  OID on that Regular Certificate. In computing
the daily portions of OID for such a purchaser (as well as an initial  purchaser
that purchases at a price higher than the adjusted issue price but less than the
stated  redemption price at maturity), however,  the daily portion is reduced by
the amount that would be the daily portion for such day (computed in  accordance
with the rules set forth above) multiplied by a fraction, the numerator of which
is  the amount, if any, by which the  price paid by such holder for that Regular
Certificate exceeds the following  amount: (a) the sum  of the issue price  plus
the  aggregate amount of OID that would have been includible in the gross income
of an original Regular Certificateholder (who purchased the Regular  Certificate
at  its  issue  price), less  (b)  any  prior payments  included  in  the stated
redemption price at maturity,  and the denominator  of which is  the sum of  the
daily  portions for that Regular Certificate for  all days beginning on the date
after the  purchase date  and ending  on the  maturity date  computed under  the
Prepayment  Assumption. A  holder who  pays an  acquisition premium  instead may
elect to accrue OID by treating the purchase as a purchase at original issue.
 
     Variable Rate Regular Certificates.   Regular Certificates may provide  for
interest  based on a variable rate. Interest is treated as payable at a variable
rate and not as contingent interest if, generally, (i) the issue price does  not
exceed  the original principal balance by more  than a specified amount and (ii)
the interest compounds  or is  payable at least  annually at  current values  of
certain  objective rates matured by or based on lending rates for newly borrowed
funds. The variable interest generally will be qualified stated interest to  the
extent  it  is unconditionally  payable  at least  annually  and, to  the extent
successive variable rates are used, interest is not significantly accelerated or
deferred.
 
     The amount of OID with respect to a Regular Certificate bearing a  variable
rate  of interest will accrue in the  manner described above under ' -- Original
Issue Discount and Premium'  by assuming generally that  the index used for  the
variable  rate  will  remain  fixed  throughout  the  term  of  the Certificate.
Appropriate adjustments are made for the actual variable rate.
 
     Although unclear  at  present,  the  Depositor  intends  to  treat  Regular
Certificates  bearing an  interest rate  that is a  weighted average  of the net
interest rates on Mortgage  Loans as variable rate  certificates. In such  case,
the  weighted average rate used to compute  the initial pass-through rate on the
Regular Certificates will be deemed to be  the index in effect through the  life
of  the Regular Certificates.  It is possible,  however, that the  IRS may treat
some or all of the interest on Regular Certificates with a weighted average rate
as taxable  under the  rules relating  to obligations  providing for  contingent
payments.  Such  treatment may  effect  the timing  of  income accruals  on such
Regular Certificates. Additionally,  if some or  all of the  Mortgage Loans  are
subject  to 'teaser rates'  (i.e., the initial  rates on the  Mortgage Loans are
less than subsequent rates on the Mortgage  Loans) the interest paid on some  or
all of the Regular Certificates may be subject to accrual using a constant yield
method  notwithstanding the fact that such Certificates may not have been issued
with 'true' non-de minimis original issue discount.
 
     Election to  Treat  All Interest  as  OID.  The OID  Regulations  permit  a
Certificateholder  to  elect  to  accrue all  interest,  discount  (including de
minimus market or original  issue discount) and premium  in income as  interest,
based  on a constant yield method for Certificates acquired on or after April 4,
1994. If such an election were to be made with respect to a Regular  Certificate
with  market discount,  the Certificateholder  would be  deemed to  have made an
election to include  in income  currently market  discount with  respect to  all
other  debt  instruments  having  market  discount  that  such Certificateholder
acquires  during  the  year  of   the  election  or  thereafter.  Similarly,   a
Certificateholder that makes this election for a Certificate that is acquired 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
Certificateholder  owns or acquires.  See ' --  Regular Certificates -- Premium'
herein. The election  to accrue  interest, discount  and premium  on a  constant
yield method with respect to a Certificate cannot be revoked without the consent
of the IRS.
 
     Market  Discount.  A purchaser of a Regular Certificate may also be subject
to the market  discount provisions  of Code  Sections 1276  through 1278.  Under
these  provisions and the OID Regulations,  'market discount' equals the excess,
if any, of (i) the Regular Certificate's stated principal amount or, in the case
of a Regular Certificate with OID, the adjusted issue price (determined for this
purpose as  if the  purchaser had  purchased such  Regular Certificate  from  an
original  holder) over (ii) the  price for such Regular  Certificate paid by the
purchaser. A Certificateholder that purchases a Regular Certificate at a  market
discount  will recognize income  upon receipt of  each distribution representing
stated redemption price. In  particular, under Section 1276  of the Code such  a
holder  generally will be required to  allocate each such principal distribution
first to  accrued market  discount not  previously included  in income,  and  to
recognize ordinary income to that extent. A
 
                                       65

Certificateholder may elect to include market discount in income currently as it
accrues  rather than  including it  on a deferred  basis in  accordance with the
foregoing. If  made, such  election  will apply  to  all market  discount  bonds
acquired  by  such Certificateholder  on or  after  the first  day of  the first
taxable year to which such election applies.
 
     Market discount with respect to a Regular Certificate will be considered to
be zero if the amount allocable to the Regular Certificate is less than 0.25% of
such Regular Certificate's  stated redemption  price at  maturity multiplied  by
such Regular Certificate's weighted average maturity remaining after the date of
purchase.  If market discount on a Regular  Certificate is considered to be zero
under this rule, the actual amount of  market discount must be allocated to  the
remaining  principal payments on the Regular Certificate, and gain equal to such
allocated amount will be recognized when the corresponding principal payment  is
made.  Treasury regulations implementing the market  discount rules have not yet
been  issued;  therefore,  investors  should  consult  their  own  tax  advisors
regarding  the application of these rules and  the advisability of making any of
the elections allowed under Code Sections 1276 through 1278.
 
     The Code provides that any  principal payment (whether a scheduled  payment
or  a prepayment) or any gain on  disposition of a market discount bond acquired
by the taxpayer after October 22, 1986,  shall be treated as ordinary income  to
the  extent that it does  not exceed the accrued market  discount at the time of
such payment. The amount of accrued market discount for purposes of  determining
the tax treatment of subsequent principal payments or dispositions of the market
discount bond is to be reduced by the amount so treated as ordinary income.
 
     The  Code  also  grants  authority  to  the  Treasury  Department  to issue
regulations providing for  the computation  of accrued market  discount on  debt
instruments,  the principal  of which is  payable in more  than one installment.
Until such time as  regulations are issued by  the Treasury, rules described  in
the  Legislative History will apply.  Under those rules, the  holder of a market
discount bond may  elect to  accrue market  discount either  on the  basis of  a
constant interest rate or according to one of the following methods. For Regular
Certificates  issued with OID, the amount of market discount that accrues during
a period is equal to the product of (i) the total remaining market discount  and
(ii)  a fraction, the numerator  of which is the  OID accruing during the period
and the denominator of which is the total remaining OID at the beginning of  the
period.  For  Regular  Certificates issued  without  OID, the  amount  of market
discount that accrues during a period is  equal to the product of (a) the  total
remaining  market discount  and (b)  a fraction, the  numerator of  which is the
amount of stated interest paid during the accrual period and the denominator  of
which  is  the total  amount  of stated  interest remaining  to  be paid  at the
beginning of the period. For purposes  of calculating market discount under  any
of  the  above  methods  in  the  case  of  instruments  (such  as  the  Regular
Certificates) that provide  for payments that  may be accelerated  by reason  of
prepayments  of other obligations securing such instruments, the same Prepayment
Assumption applicable to calculating the accrual of OID will apply.
 
     A holder of a Regular Certificate that acquires such Regular Certificate at
a market discount also may be required to defer, until the maturity date of such
Regular Certificate or  its earlier  disposition in a  taxable transaction,  the
deduction of a portion of the amount of interest that the holder paid or accrued
during  the taxable year  on indebtedness incurred or  maintained to purchase or
carry the Regular  Certificate in  excess of  the aggregate  amount of  interest
(including  OID) includible in  such holder's gross income  for the taxable year
with respect  to such  Regular  Certificate. The  amount  of such  net  interest
expense  deferred in a taxable year may not exceed the amount of market discount
accrued on the Regular Certificate for the days during the taxable year on which
the holder held  the Regular Certificate  and, in general,  would be  deductible
when  such market discount is includible in  income. The amount of any remaining
deferred deduction is to be taken into account in the taxable year in which  the
Regular  Certificate matures or is disposed of  in a taxable transaction. In the
case of a disposition  in which gain or  loss is not recognized  in whole or  in
part,  any remaining deferred  deduction will be  allowed to the  extent of gain
recognized on the disposition. This deferral rule does not apply if the  Regular
Certificateholder  elects to include such market discount in income currently as
it  accrues  on  all  market  discount  obligations  acquired  by  such  Regular
Certificateholder in that taxable year or thereafter.
 
     Premium.   A purchaser of a  Regular Certificate that purchases the Regular
Certificate at a cost (not including accrued qualified stated interest)  greater
than  its remaining  stated redemption price  at maturity will  be considered to
have purchased the Regular  Certificate at a premium  and may elect to  amortize
such  premium  under  a constant  yield  method.  It is  not  clear  whether the
Prepayment Assumption would be taken into account in determining the life of the
Regular Certificate for  this purpose. However,  the Legislative History  states
that  the  same rules  that apply  to  accrual of  market discount  (which rules
require use of a Prepayment Assumption in
 
                                       66
 

<PAGE>
<PAGE>

accruing market discount with respect to Regular Certificates without regard  to
whether  such Certificates have OID) will  also apply in amortizing bond premium
under Code Section 171. The Code provides that amortizable bond premium will  be
allocated  among the interest payments on  such Regular Certificates and will be
applied as an offset against such interest payment.
 
     Deferred Interest.   Certain classes of  Regular Certificates will  provide
for  the accrual of Deferred Interest with respect to one or more ARM Loans. Any
Deferred Interest that accrues with respect  to a class of Regular  Certificates
will  constitute income to  the holders of  such Certificates prior  to the time
distributions of cash  with respect to  such Deferred Interest  are made. It  is
unclear,  under  the  OID  Regulations,  whether any  of  the  interest  on such
Certificates will  constitute qualified  stated  interest or  whether all  or  a
portion  of the interest  payable on such  Certificates must be  included in the
stated redemption price at maturity of the Certificates and accounted for as OID
(which could accelerate such inclusion).  Interest on Regular Certificates  must
in  any event be  accounted for under an  accrual method by  the holders of such
Certificates and, therefore, applying the latter  analysis may result only in  a
slight  difference in the timing of the  inclusion in income of interest on such
Regular Certificates.
 
     Effects of Defaults and Delinquencies.  Certain Series of Certificates  may
contain one or more classes of Subordinated Certificates, and in the event there
are  defaults  or  delinquencies  on  the  Mortgage  Loans,  amounts  that would
otherwise be  distributed  on  the  Subordinated  Certificates  may  instead  be
distributed  on the  Certificates. Subordinated  Certificateholders nevertheless
will be required  to report income  with respect to  such Certificates under  an
accrual  method without giving effect to  delays and reductions in distributions
on such Subordinated Certificates attributable to defaults and delinquencies  on
the  Mortgage Loans, except to  the extent that it  can be established that such
amounts are  uncollectible. As  a result,  the amount  of income  reported by  a
Subordinated  Certificateholder  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
Subordinated Certificate is reduced as a result of defaults and delinquencies on
the  Mortgage Loans. However, the timing  and characterization of such losses or
reductions   in   income   are   uncertain,   and,   accordingly,   Subordinated
Certificateholders should consult their own tax advisors on this point.
 
     Sale,  Exchange or Redemption. If a Regular Certificate is sold, exchanged,
redeemed or  retired,  the seller  will  recognize gain  or  loss equal  to  the
difference  between the  amount realized on  the sale,  exchange, redemption, or
retirement and  the seller's  adjusted basis  in the  Regular Certificate.  Such
adjusted  basis generally will equal the cost  of the Regular Certificate to the
seller, increased by any OID and market discount included in the seller's  gross
income with respect to the Regular Certificate, and reduced (but not below zero)
by  payments  included in  the stated  redemption  price at  maturity previously
received by the  seller and by  any amortized premium.  Similarly, a holder  who
receives  a payment that is part of the stated redemption price at maturity of a
Regular Certificate will  recognize gain  equal to the  excess, if  any, of  the
amount  of  the  payment  over  the  holder's  adjusted  basis  in  the  Regular
Certificate. A Regular Certificateholder  who receives a  final payment that  is
less  than the holder's adjusted basis in the Regular Certificate will generally
recognize a loss. Except as provided in the following paragraph and as  provided
under  'Market Discount' above,  any such gain  or loss will  be capital gain or
loss, provided  that  the Regular  Certificate  is  held as  a  'capital  asset'
(generally,  property held  for investment) within  the meaning  of Code Section
1221.
 
     Gain from the sale or other disposition of a Regular Certificate that might
otherwise be capital gain will be treated as ordinary income to the extent  that
such  gain does not exceed the excess, if any, of (i) the amount that would have
been includible in such holder's income with respect to the Regular  Certificate
had income accrued thereon at a rate equal to 110% of the AFR as defined in Code
Section  1274(d)  determined  as  of  the  date  of  purchase  of  such  Regular
Certificate, over (ii) the amount actually includible in such holder's income.
 
     The Regular Certificates  will be  'evidences of  indebtedness' within  the
meaning of Code Section 582(c)(1), so that gain or loss recognized from the sale
of a Regular Certificate by a bank or a thrift institution to which such section
applies will be ordinary income or loss.
 
     The Regular Certificate information reports will include a statement of the
adjusted issue price of the Regular Certificate at the beginning of each accrual
period.  In addition, the reports will  include information necessary to compute
the accrual of  any market  discount that may  arise upon  secondary trading  of
Regular  Certificates.  Because  exact  computation  of  the  accrual  of market
discount on a constant  yield method would require  information relating to  the
holder's  purchase  price which  the REMIC  may  not have,  it appears  that the
 
                                       67
 

<PAGE>
<PAGE>

information reports will only require information pertaining to the  appropriate
proportionate method of accruing market discount.
 
     Accrued  Interest  Certificates.    Certain  of  the  Regular  Certificates
('Payment Lag Certificates')  may provide for  payments of interest  based on  a
period that corresponds to the interval between Distribution Dates but that ends
prior  to each such Distribution  Date. The period between  the Closing Date for
Payment Lag Certificates and their first Distribution Date may or may not exceed
such interval.  Purchasers of  Payment  Lag Certificates  for which  the  period
between  the Closing Date and  the first Distribution Date  does not exceed such
interval could pay upon purchase of the Regular Certificates accrued interest in
excess of the accrued interest  that would be paid if  the interest paid on  the
Distribution  Date were interest accrued  from Distribution Date to Distribution
Date. If a portion  of the initial  purchase price of  a Regular Certificate  is
allocable  to interest that  has accrued prior to  the issue date ('pre-issuance
accrued interest') and the Regular Certificate provides for a payment of  stated
interest  on the first  payment date (and  the first payment  date is within one
year of the issue date)  that equals or exceeds  the amount of the  pre-issuance
accrued  interest, then the Regular Certificates' issue price may be computed by
subtracting from the issue  price the amount  of pre-issuance accrued  interest,
rather  than as  an amount  payable on the  Regular Certificate.  However, it is
unclear under this method how the OID Regulations treat interest on Payment  Lag
Certificates.  Therefore, in  the case of  a Payment Lag  Certificate, the Trust
Fund intends to include accrued interest in the issue price and report  interest
payments  made on  the first  Distribution Date as  interest to  the extent such
payments represent interest for  the number of  days that the  Certificateholder
has held such Payment Lag Certificate during the first accrual period.
 
     Investors  should consult their  own tax advisors  concerning the treatment
for federal income tax purposes of Payment Lag Certificates.
 
     Non-Interest  Expenses  of  the  REMIC.    Under  the  temporary   Treasury
regulations,  if the REMIC is considered to be a 'single-class REMIC,' a portion
of the REMIC's servicing, administrative and other non-interest expenses will be
allocated as  a  separate item  to  those Regular  Certificateholders  that  are
'pass-through   interest  holders.'  Certificateholders  that  are  pass-through
interest holders should consult their own tax advisors about the impact of these
rules on  an  investment  in  the Regular  Certificates.  See  'Pass-Through  of
Non-Interest Expenses of the REMIC' under 'Residual Certificates' below.
 
     Treatment  of Realized Losses. Although not entirely clear, it appears that
holders of  Regular Certificates  that  are corporations  should in  general  be
allowed to deduct as an ordinary loss any loss sustained during the taxable year
on  account of any such Certificates becoming wholly or partially worthless, and
that, in general, holders  of Certificates that are  not corporations should  be
allowed  to deduct as  a short-term capital  loss any loss  sustained during the
taxable year  on account  of any  such Certificates  becoming wholly  worthless.
Although  the matter  is unclear, non-corporate  holders of  Certificates may be
allowed a bad debt deduction at such time that the principal balance of any such
Certificate is reduced to reflect realized losses resulting from any  liquidated
Mortgage  Loans. The Internal Revenue Service,  however, could take the position
that non-corporate  holders will  be allowed  a bad  debt deduction  to  reflect
realized  losses only  after all Mortgage  Loans remaining in  the related Trust
Fund have been liquidated  or the Certificates of  the related Series have  been
otherwise retired. Potential investors and Holders of the Certificates are urged
to  consult their own tax advisors  regarding the appropriate timing, amount and
character of any loss sustained with respect to such Certificates, including any
loss resulting  from  the failure  to  recover previously  accrued  interest  or
discount  income.  Special  loss  rules  are  applicable  to  banks  and  thrift
institutions, including rules regarding reserves  for bad debts. Such  taxpayers
are  advised to consult their tax advisors  regarding the treatment of losses on
Certificates.
 
     Non-U.S. Persons.  Generally, payments  of interest (including any  payment
with  respect  to  accrued  OID)  on  the  Regular  Certificates  to  a  Regular
Certificateholder who is  not a U.S.  Person and is  not engaged in  a trade  or
business within the United States will not be subject to federal withholding tax
if   such  Regular   Certificateholder  complies   with  certain  identification
requirements  (including  delivery  of  a  statement,  signed  by  the   Regular
Certificateholder  under  penalties  of perjury,  certifying  that  such Regular
Certificateholder is a foreign person and providing the name and address of such
Regular Certificateholder). If  a Regular Certificateholder  is not exempt  from
withholding,  distributions of  interest, including distributions  in respect of
accrued OID, such holder  may be subject  to a 30%  withholding tax, subject  to
reduction under any applicable tax treaty.
 
                                       68

     Further, it appears that a Regular Certificate would not be included in the
estate  of a non-resident  alien individual and  would not be  subject to United
States estate  taxes. However,  Certificateholders  who are  non-resident  alien
individuals should consult their tax advisors concerning this question.
 
     Regular  Certificateholders who are not U.S. Persons and persons related to
such holders  should  not acquire  any  Residual Certificates,  and  holders  of
Residual  Certificates (the 'Residual Certificateholder') and persons related to
Residual Certificateholders should not acquire any Regular Certificates  without
consulting  their tax  advisors as to  the possible adverse  tax consequences of
doing so.
 
     Information Reporting and  Backup Withholding.   The  Master Servicer  will
furnish  or  make available,  within a  reasonable  time after  the end  of each
calendar year, to each  person who was a  Regular Certificateholder at any  time
during  such year, such information  as may be deemed  necessary or desirable to
assist Regular Certificateholders in preparing their federal income tax returns,
or to enable holders to make such information available to beneficial owners  or
financial  intermediaries  that  hold  such Regular  Certificates  on  behalf of
beneficial owners.  If a  holder, beneficial  owner, financial  intermediary  or
other  recipient of a payment on behalf of  a beneficial owner fails to supply a
certified taxpayer identification  number or  if the Secretary  of the  Treasury
determines  that such person  has not reported all  interest and dividend income
required to be shown  on its federal income  tax return, 31% backup  withholding
may  be required with respect to any payments. Any amounts deducted and withheld
from a distribution to  a recipient would  be allowed as  a credit against  such
recipient's federal income tax liability.
 
B. RESIDUAL CERTIFICATES
 
     Allocation  of the Income of  the REMIC to the  Residual Certificates.  The
REMIC will not be subject  to federal income tax  except with respect to  income
from prohibited transactions and certain other transactions. See ' -- Prohibited
Transactions and Other Taxes' below. Instead, each original holder of a Residual
Certificate  will report on  its federal income tax  return, as ordinary income,
its share of the  taxable income of  the REMIC for each  day during the  taxable
year  on which such holder owns any Residual Certificates. The taxable income of
the REMIC for each day  will be determined by  allocating the taxable income  of
the  REMIC for each calendar quarter ratably to  each day in the quarter. Such a
holder's share of the taxable income of the REMIC for each day will be based  on
the  portion of the  outstanding Residual Certificates that  such holder owns on
that day. The taxable income  of the REMIC will  be determined under an  accrual
method  and  will be  taxable to  the holders  of Residual  Certificates without
regard to the  timing or amounts  of cash distributions  by the REMIC.  Ordinary
income  derived  from  Residual  Certificates  will  be  'portfolio  income' for
purposes of  the  taxation  of  taxpayers subject  to  the  limitations  on  the
deductibility   of  'passive  losses.'  As   residual  interests,  the  Residual
Certificates will be  subject to tax  rules, described below,  that differ  from
those  that would  apply if the  Residual Certificates were  treated for federal
income tax purposes as direct ownership interests in the Certificates or as debt
instruments issued by the REMIC.
 
     A Residual Certificateholder may be required to include taxable income from
the Residual  Certificate in  excess of  the cash  distributed. For  example,  a
structure  where principal distributions are  made serially on regular interests
(that is, a  fast-pay, slow-pay structure)  may generate such  a mismatching  of
income  and cash distributions (that is, 'phantom income'). This mismatching may
be caused by the use  of certain required tax  accounting methods by the  REMIC,
variations  in the prepayment rate of  the underlying Mortgage Loans and certain
other factors. Depending  upon the  structure of a  particular transaction,  the
aforementioned  factors  may  significantly  reduce  the  after-tax  yield  of a
Residual Certificate to a  Residual Certificateholder. Investors should  consult
their own tax advisors concerning the federal income tax treatment of a Residual
Certificate  and the impact  of such tax  treatment on the  after-tax yield of a
Residual Certificate.
 
     A subsequent Residual  Certificateholder also  will report  on its  federal
income  tax return amounts representing  a daily share of  the taxable income of
the REMIC for each day that  such Residual Certificateholder owns such  Residual
Certificate.  Those daily amounts  generally would equal  the amounts that would
have been reported for the same days by an original Residual  Certificateholder,
as  described above. The Legislative  History indicates that certain adjustments
may be appropriate to reduce (or increase) the income of a subsequent holder  of
a  Residual  Certificate that  purchased such  Residual  Certificate at  a price
greater than (or less than) the  adjusted basis such Residual Certificate  would
have  in the hands of  an original Residual Certificateholder.  See ' -- Sale or
Exchange of Residual Certificates' below. It is not clear, however, whether such
adjustments will in fact be permitted or required and, if so, how they would  be
made. The REMIC Regulations do not provide for any such adjustments.
 
                                       69

     Taxable  Income  of  the REMIC  Attributable  to Residual  Interests.   The
taxable income of the REMIC  will reflect a netting of  (i) the income from  the
Mortgage  Loans and the REMIC's other assets  and (ii) the deductions allowed to
the REMIC  for interest  and OID  on  the Regular  Certificates and,  except  as
described  above under ' -- Regular Certificates -- Non-Interest Expenses of the
REMIC,' other expenses. REMIC taxable income is generally determined in the same
manner as  the taxable  income of  an  individual using  the accrual  method  of
accounting,  except  that (i)  the  limitations on  deductibility  of investment
interest expense and expenses  for the production of  income do not apply,  (ii)
all bad loans will be deductible as business bad debts, and (iii) the limitation
on  the deductibility of  interest and expenses related  to tax-exempt income is
more restrictive  than with  respect  to individual.  The REMIC's  gross  income
includes  interest, original issue discount  income, and market discount income,
if any,  on  the  Mortgage Loans,  as  well  as, income  earned  from  temporary
investments on reverse assets, reduced by the amortization of any premium on the
Mortgage  Loans.  In  addition,  a  Residual  Certificateholder  will  recognize
additional income  due to  the  allocation of  realized  losses to  the  Regular
Certificates  due to defaults, delinquencies and realized losses on the Mortgage
Loans. The timing of the inclusion of such income by Residual Certificateholders
may  differ  from  the  time  the  actual  loss  is  allocated  to  the  Regular
Certificates.  The  REMIC's  deductions  include  interest  and  original  issue
discount expense on  the Regular  Certificates, servicing fees  on the  Mortgage
Loans,  other administrative  expenses of the  REMIC and realized  losses on the
Mortgage Loans. The  requirement that Residual  Certificateholders report  their
pro  rata share of taxable  income or net loss of  the REMIC will continue until
there are no Certificates of any class of the related Series outstanding.
 
     For purposes of  determining its  taxable income,  the REMIC  will have  an
initial  aggregate tax basis in its assets equal  to the sum of the issue prices
of the Regular  Certificates and the  Residual Certificates (or,  if a class  of
Certificates is not sold initially, its fair market value). Such aggregate basis
will  be allocated  among the Mortgage  Loans and  other assets of  the REMIC in
proportion to their respective fair market value. A Mortgage Loan will be deemed
to have been acquired with  discount or premium to  the extent that the  REMIC's
basis  therein is less than or greater than its principal balance, respectively.
Any such discount  (whether market discount  or OID) will  be includible in  the
income  of  the  REMIC  as  it  accrues,  in  advance  of  receipt  of  the cash
attributable to such  income, under  a method  similar to  the method  described
above  for accruing OID on the Regular  Certificates. The REMIC expects to elect
under Code Section 171 to amortize any premium on the Mortgage Loans. Premium on
any Mortgage Loan  to which  such election applies  would be  amortized under  a
constant  yield method.  It is not  clear whether  the yield of  a Mortgage Loan
would be  calculated for  this purpose  based on  scheduled payments  or  taking
account  of the Prepayment Assumption. Additionally,  such an election would not
apply to the yield with respect to any underlying mortgage loan originated on or
before September 27, 1985. Instead, premium with respect to such a mortgage loan
would be allocated among the principal payments thereon and would be  deductible
by the REMIC as those payments become due.
 
     The  REMIC will be allowed a deduction  for interest and OID on the Regular
Certificates. The amount  and method of  accrual of OID  will be calculated  for
this  purpose in  the same  manner as  described above  with respect  to Regular
Certificates except that the 0.25% per annum de minimis rule and adjustments for
subsequent holders described therein will not apply.
 
     A Residual Certificateholder will not be permitted to amortize the cost  of
the  Residual  Certificate as  an offset  to  its share  of the  REMIC's taxable
income. However, that taxable income will not include cash received by the REMIC
that represents a recovery of the REMIC's basis in its assets, and, as described
above, the issue price of the Residual  Certificates will be added to the  issue
price  of the Regular  Certificates in determining the  REMIC's initial basis in
its assets. See '  -- Sale or  Exchange of Residual  Certificates' below. For  a
discussion  of  possible  adjustments to  income  of  a subsequent  holder  of a
Residual Certificate to reflect any difference  between the actual cost of  such
Residual  Certificate  to  such  holder and  the  adjusted  basis  such Residual
Certificate would have in the  hands of an original Residual  Certificateholder,
see  ' -- Allocation  of the Income  of the REMIC  to the Residual Certificates'
above.
 
     Net Losses of the REMIC.  The REMIC  will have a net loss for any  calendar
quarter  in which its deductions exceed its gross income. Such net loss would be
allocated among  the  Residual Certificateholders  in  the same  manner  as  the
REMIC's  taxable income. The net loss allocable to any Residual Certificate will
not be deductible by the  holder to the extent that  such net loss exceeds  such
holder's  adjusted basis in such Residual Certificate.  Any net loss that is not
currently deductible  by reason  of this  limitation may  only be  used by  such
Residual  Certificateholder to offset its share of the REMIC's taxable income in
future periods (but not
 
                                       70
 

<PAGE>
<PAGE>

otherwise). The ability of Residual  Certificateholders that are individuals  or
closely  held corporations  to deduct  net losses  may be  subject to additional
limitations under the Code.
 
     Mark to Market  Rules.   Prospective purchasers of  a Residual  Certificate
should be aware that on December 28, 1993, the Internal Revenue Service released
temporary  Treasury  regulations (the  'Temporary  Mark to  Market Regulations')
relating to the requirement that  a securities dealer mark-to-market  securities
held  for  sale to  customers. This  mark-to-market  requirement applies  to all
securities of a dealer,  except to the extent  that the dealer has  specifically
identified  a  security as  held for  investment. The  Temporary Mark  to Market
Regulations provide  that for  purposes of  this mark-to-market  requirement,  a
'negative  value' REMIC residual interest is not  treated as a security and thus
may not be marked to market. In  addition, a dealer is not required to  identify
such  Residual  Certificate  as  held for  investment.  In  general,  a Residual
Certificate has  negative value  if, as  of  the date  a taxpayer  acquires  the
Residual  Certificate, the present value of  the tax liabilities associated with
holding the Residual Certificate exceeds the sum of (i) the present value of the
expected future distributions on the Residual Certificate, and (ii) the  present
value  of  the  anticipated tax  savings  associated with  holding  the Residual
Certificate as the REMIC generates losses. The amounts and present values of the
anticipated tax liabilities, expected  future distributions and anticipated  tax
savings  are  all to  be determined  using (i)  the prepayment  and reinvestment
assumptions adopted under Section  1272(a)(6), or that  would have been  adopted
had the REMIC's regular interests been issued with original issue discount, (ii)
any  required or  permitted clean  up calls,  or required  qualified liquidation
provided for in the REMIC's organizational  documents and (iii) a discount  rate
equal  to the 'applicable Federal rate' (as specified in Section 1274(d)(1) that
would apply  to a  debt instrument  issued on  the date  of acquisition  of  the
Residual  Certificate.  Furthermore, the  Temporary  Mark to  Market Regulations
provide the IRS  with the  authority to  treat any  Residual Certificate  having
substantially  the same economic effect as  a 'negative value' residual interest
as a  'negative  value'  residual  interest.  The  IRS  could  issue  subsequent
regulations,  which could apply retroactively, providing additional or different
requirements with  respect to  such deemed  negative value  residual  interests.
Prospective  purchasers  of  a  Residual Certificate  should  consult  their tax
advisors regarding  the possible  application of  the Temporary  Mark to  Market
Regulations.
 
     Pass-Through of Non-Interest Expenses of the REMIC.  As a general rule, all
of the fees and expenses of a REMIC will be taken into account by holders of the
Residual  Certificates.  In  the case  of  a  single class  REMIC,  however, the
expenses and a  matching amount of  additional income will  be allocated,  under
temporary  Treasury regulations,  among the  Regular Certificateholders  and the
Residual Certificateholders  on a  daily  basis in  proportion to  the  relative
amounts  of income  accruing to each  Certificateholder on that  day. In general
terms, a single class REMIC is one that either (i) would qualify, under existing
Treasury regulations, as a grantor  trust if it were  not a REMIC (treating  all
interests  as ownership interests, even if they  would be classified as debt for
federal income  tax  purposes)  or (ii)  is  similar  to such  a  trust  and  is
structured  with the principal purpose of avoiding the single class REMIC rules.
Unless otherwise stated in the applicable Prospectus Supplement, the expenses of
the REMIC will be allocated to  holders of the related Residual Certificates  in
their entirety and not to holders of the related Regular Certificates.
 
     In  the  case of  individuals  (or trusts,  estates  or other  persons that
compute their income in the same manner as individuals) who own an interest in a
Regular Certificate or a Residual Certificate directly or through a pass-through
interest holder  that  is required  to  pass miscellaneous  itemized  deductions
through  to its owners or beneficiaries (e.g. a partnership, an S corporation or
a grantor trust), such expenses will be deductible under Code Section 67 only to
the extent that such expenses, plus other 'miscellaneous itemized deductions' of
the individual,  exceed  2%  of  such individual's  adjusted  gross  income.  In
addition,  Code  Section  68 provides  that  the amount  of  itemized deductions
otherwise allowable  for an  individual whose  adjusted gross  income exceeds  a
certain amount (the 'Applicable Amount') will be reduced by the lesser of (i) 3%
of  the excess  of the  individual's adjusted  gross income  over the Applicable
Amount or (ii) 80% of the amount of itemized deductions otherwise allowable  for
the taxable year. The amount of additional taxable income recognized by Residual
Certificateholders  who are subject to the limitations of either Code Section 67
or  Code  Section  68   may  be  substantial.   Further,  holders  (other   than
corporations)   subject  to   the  alternative   minimum  tax   may  not  deduct
miscellaneous itemized  deductions  in  determining  such  holders'  alternative
minimum  taxable income.  The REMIC is  required to report  to each pass-through
interest holder and to  the IRS such  holder's allocable share,  if any, of  the
REMIC's non-interest expenses. The term 'pass-through interest holder' generally
refers  to individuals, entities  taxed as individuals  and certain pass-through
entities, but does not include real estate

investment trusts. Residual  Certificateholders that  are pass-through  interest
holders should consult their own tax advisors about the impact of these rules on
an investment in the Residual Certificates.
 
     Excess  Inclusions.   A  portion of  the income  on a  Residual Certificate
(referred to in  the Code  as an 'excess  inclusion') for  any calendar  quarter
will,  with an  exception discussed  below for  certain thrift  institutions, be
subject to  federal income  tax in  all  events. Thus,  for example,  an  excess
inclusion  (i) may not,  except as described  below, be offset  by any unrelated
losses, deductions or loss carryovers of a Residual Certificateholder; (ii) will
be treated as  'unrelated business taxable  income' within the  meaning of  Code
Section  512 if the  Residual Certificateholder is  a pension fund  or any other
organization that  is subject  to tax  only on  its unrelated  business  taxable
income (see ' -- Tax-Exempt Investors' below); and (iii) is not eligible for any
reduction   in  the  rate  of  withholding  tax   in  the  case  of  a  Residual
Certificateholder that is a foreign investor. See ' -- Non-U.S. Persons'  below.
The  exception  for thrift  institutions is  available  only to  the institution
holding the Residual Certificate  and not to any  affiliate of the  institution,
unless  the affiliate is a subsidiary all  the stock of which, and substantially
all the  indebtedness  of  which, is  held  by  the institution,  and  which  is
organized  and  operated exclusively  in  connection with  the  organization and
operation of one or more REMICs.
 
     Except as  discussed  in  the  following paragraph,  with  respect  to  any
Residual  Certificateholder, the excess  inclusions for any  calendar quarter is
the excess, if  any, of (i)  the income of  such Residual Certificateholder  for
that  calendar quarter from  its Residual Certificate  over (ii) the  sum of the
'daily accruals' (as defined below) for all days during the calendar quarter  on
which  the Residual Certificateholder holds  such Residual Certificate. For this
purpose,  the  daily  accruals  with  respect  to  a  Residual  Certificate  are
determined by allocating to each day in the calendar quarter its ratable portion
of  the product of the 'adjusted issue price' (as defined below) of the Residual
Certificate at the  beginning of  the calendar quarter  and 120  percent of  the
'Federal  long-term  rate' in  effect at  the time  the Residual  Certificate is
issued. For this purpose, the 'adjusted  issue price' of a Residual  Certificate
at  the beginning of any calendar quarter equals the issue price of the Residual
Certificate, increased by the amount of  daily accruals for all prior  quarters,
and  decreased (but not below zero) by  the aggregate amount of payments made on
the Residual  Certificate before  the beginning  of such  quarter. The  'federal
long-term  rate' is an average  of current yields on  Treasury securities with a
remaining term of greater than nine years, computed and published monthly by the
IRS.
 
     As  an  exception  to  the  general  rule  described  above,  the  Treasury
Department has authority to issue regulations that would treat the entire amount
of  income  accruing  on a  Residual  Certificate  as excess  inclusions  if the
Residual Certificates in the aggregate  are considered not to have  'significant
value.' Under the REMIC Regulations, Residual Certificateholders that are thrift
institutions  described in  Code Section 593  can offset  excess inclusions with
unrelated  deductions,  losses  and   loss  carryovers  provided  the   Residual
Certificates  have  'significant value.'  For  purposes of  applying  this rule,
thrift  institutions  that  are  members   of  an  affiliated  group  filing   a
consolidated  return, together with  their subsidiaries formed  to issue REMICs,
are treated as  separate corporations. Residual  Certificates have  'significant
value'  if: (i) the Residual Certificates have  an aggregate issue price that is
at least equal to 2% of the  aggregate issue price of all Residual  Certificates
and  Regular Certificates  with respect  to the  REMIC and  (ii) the anticipated
weighted average  life of  the Residual  Certificates  is at  least 20%  of  the
anticipated  weighted  average  life  of  the  REMIC  based  on  the anticipated
principal payments to  be received  with respect thereto  (using the  Prepayment
Assumption  and any required or permitted clean up calls or required liquidation
provided  for  in  the  REMIC's  organizational  documents),  except  that   all
anticipated  distributions are to be used to calculate the weighted average life
of Regular Certificates that are not  entitled to any principal payments or  are
entitled  to a  disproportionately small  principal amount  relative to interest
payments thereon and all anticipated distributions  are to be used to  calculate
the  weighted average  life of the  Residual Certificates.  The principal amount
will be considered disproportionately small if  the issue price of the  Residual
Certificates  exceeds  125%  of  their  initial  principal  amount.  Finally, an
ordering rule under the REMIC Regulations provides that a thrift institution may
only offset  its excess  inclusion income  with deductions  after it  has  first
applied its deductions against income that is not excess inclusion income.
 
     In  the case of any Residual Certificates  held by a real estate investment
trust,  the  aggregate   excess  inclusions  with   respect  to  such   Residual
Certificates,  reduced (but not below zero)  by the real estate investment trust
taxable income (within the meaning of Code Section 857(b)(2), excluding any  net
capital  gain),  will  be allocated  among  the  shareholders of  such  trust in
proportion to the dividends received by  such shareholders from such trust,  and
any amount so allocated will be treated as an excess inclusion with respect to a
Residual  Certificate  as  if  held  directly  by  such  shareholder.  Regulated
investment companies, common trust funds and certain cooperatives are subject to
similar rules.
 
                                       72

     Payments.  Any distribution  made on a Residual  Certificate to a  Residual
Certificateholder  will be  treated as  a non-taxable  return of  capital to the
extent it does  not exceed  the Residual Certificateholder's  adjusted basis  in
such  Residual Certificate. To  the extent a  distribution exceeds such adjusted
basis, it will be treated as gain from the sale of the Residual Certificate.
 
     Sale or Exchange of  Residual Certificates.  If  a Residual Certificate  is
sold or exchanged, the seller will generally recognize gain or loss equal to the
difference  between the amount realized on the sale or exchange and its adjusted
basis in the Residual  Certificate (except that the  recognition of loss may  be
limited  under the 'wash sale' rules described below). A holder's adjusted basis
in a Residual Certificate generally equals the cost of such Residual Certificate
to such Residual Certificateholder, increased by the taxable income of the REMIC
that was included in the income of such Residual Certificateholder with  respect
to  such Residual  Certificate, and  decreased (but not  below zero)  by the net
losses that have been allowed  as deductions to such Residual  Certificateholder
with  respect to  such Residual  Certificate and  by the  distributions received
thereon by such Residual  Certificateholder. In general, any  such gain or  loss
will  be capital  gain or loss  provided the  Residual Certificate is  held as a
capital  asset.   However,  Residual   Certificates   will  be   'evidences   of
indebtedness' within the meaning of Code Section 582(c)(1), so that gain or loss
recognized  from sale of a Residual Certificate  by a bank or thrift institution
to which such section applies would be ordinary income or loss.
 
     Except as provided in Treasury regulations yet to be issued, if the  seller
of  a Residual Certificate reacquires such Residual Certificate, or acquires any
other Residual Certificate, any  residual interest in  another REMIC or  similar
interest  in  a 'taxable  mortgage pool'  (as defined  in Code  Section 7701(i))
during the period beginning six months before, and ending six months after,  the
date  of such sale, such sale  will be subject to the  'wash sale' rules of Code
Section 1091. In that event, any loss realized by the Residual Certificateholder
on the sale will  not be deductible, but,  instead, will increase such  Residual
Certificateholder's adjusted basis in the newly acquired asset.
 
PROHIBITED TRANSACTIONS AND OTHER TAXES
 
     The  Code imposes a  tax on REMICs equal  to 100 percent  of the net income
derived from 'prohibited transactions'  (the 'Prohibited Transactions Tax').  In
general, subject to certain specified exceptions, a prohibited transaction means
the  disposition of a Mortgage  Loan, the receipt of  income from a source other
than a Mortgage  Loan or  certain other  permitted investments,  the receipt  of
compensation  for services, or  gain from the disposition  of an asset purchased
with the  payments  on  the  Mortgage Loans  for  temporary  investment  pending
distribution  on the Certificates. It is not anticipated that the Trust Fund for
any Series of Certificates will engage  in any prohibited transactions in  which
it would recognize a material amount of net income.
 
     In  addition, certain contributions to a Trust Fund as to which an election
has been made to treat such  Trust Fund as a REMIC  made after the day on  which
such  Trust Fund issues all of its interests could result in the imposition of a
tax on the Trust  Fund equal to  100% of the value  of the contributed  property
(the  'Contributions Tax').  No Trust Fund  for any Series  of Certificates will
accept contributions that would subject it to such tax.
 
     In addition, a Trust Fund  as to which an election  has been made to  treat
such  Trust Fund as  a REMIC may  also be subject  to federal income  tax at the
highest corporate rate on 'net income from foreclosure property,' determined  by
reference  to the rules applicable to  real estate investment trusts 'Net income
from foreclosure  property' generally  means  income from  foreclosure  property
other than qualifying income for a real estate investment trust.
 
     Where any Prohibited Transactions Tax, Contributions Tax, tax on net income
from  foreclosure property or state or local income or franchise tax that may be
imposed on a  REMIC relating to  any Series  of Certificates arises  out of,  or
results  from,  (i) a  breach  of the  related  Master Servicer's,  Trustee's or
Seller's obligations, as the case may  be, under the related Agreement for  such
Series,  such tax will be  borne by such Master  Servicer, Trustee or Seller, as
the case  may be,  out of  its  own funds  or (ii)  the Seller's  obligation  to
repurchase  a Mortgage Loan, such tax will be  borne by the Seller. In the event
that such Master Servicer, Trustee or Seller,  as the case may be, fails to  pay
or  is not  required to pay  any such  tax as provided  above, such  tax will be
payable out of the Trust Fund for such Series and will result in a reduction  in
amounts available to be distributed to the Certificateholders of such Series.

LIQUIDATION AND TERMINATION
 
     If  the REMIC adopts a plan of  complete liquidation, within the meaning of
Code Section 860F(a)(4)(A)(i), which may  be accomplished by designating in  the
REMIC's  final tax return a date on which  such adoption is deemed to occur, and
sells all of its assets  (other than cash) within  a 90-day period beginning  on
such  date, the REMIC  will not be  subject to any  Prohibited Transactions Tax,
provided that the REMIC  credits or distributes in  liquidation all of the  sale
proceeds  plus its  cash (other  than the  amounts retained  to meet  claims) to
holders of Regular and Residual Certificates within the 90-day period.
 
     The REMIC will terminate  shortly following the  retirement of the  Regular
Certificates.  If a Residual Certificateholder's  adjusted basis in the Residual
Certificate  exceeds  the   amount  of   cash  distributed   to  such   Residual
Certificateholder  in final  liquidation of its  interest, then  it would appear
that the Residual  Certificateholder would be  entitled to a  loss equal to  the
amount  of such excess. It is unclear whether such a loss, if allowed, will be a
capital loss or an ordinary loss.
 
ADMINISTRATIVE MATTERS
 
     Solely for the purpose  of the administrative provisions  of the Code,  the
REMIC   generally  will   be  treated   as  a   partnership  and   the  Residual
Certificateholders will be treated as the partners. Certain information will  be
furnished  quarterly  to each  Residual  Certificateholder who  held  a Residual
Certificate on any day in the previous calendar quarter.
 
     Each Residual Certificateholder is  required to treat  items on its  return
consistently  with their  treatment on the  REMIC's return,  unless the Residual
Certificateholder either  files a  statement  identifying the  inconsistency  or
establishes  that the inconsistency resulted from incorrect information received
from the REMIC.  The IRS may  assert a  deficiency resulting from  a failure  to
comply  with the  consistency requirement without  instituting an administrative
proceeding at the REMIC level.  The REMIC does not intend  to register as a  tax
shelter  pursuant to Code  Section 6111 because  it is not  anticipated that the
REMIC will have  a net  loss for  any of  the first  five taxable  years of  its
existence. Any person that holds a Residual Certificate as a nominee for another
person  may be  required to  furnish the REMIC,  in a  manner to  be provided in
Treasury regulations,  with  the name  and  address  of such  person  and  other
information.
 
TAX-EXEMPT INVESTORS
 
     Any  Residual Certificateholder that is a pension fund or other entity that
is subject to federal  income taxation only on  its 'unrelated business  taxable
income'  within the meaning of  Code Section 512 will be  subject to such tax on
that portion of  the distributions received  on a Residual  Certificate that  is
considered  an  excess  inclusion.  See '  --  Residual  Certificates  -- Excess
Inclusions' above.
 
NON-U.S. PERSONS
 
     Amounts paid to Residual Certificateholders  who are not U.S. persons  (see
'  -- Regular Certificates  -- Non-U.S.  Persons' above) are treated as interest
for purposes of the  30% (or lower treaty  rate) United States withholding  tax.
Amounts  distributed  to  holders  of Residual  Certificates  should  qualify as
'portfolio interest,'  subject  to the  conditions  described in  '  --  Regular
Certificates'  above, but only to the  extent that the underlying mortgage loans
were originated after July 18, 1984. Furthermore, the rate of withholding on any
income on a  Residual Certificate that  is excess inclusion  income will not  be
subject  to  reduction under  any  applicable tax  treaties.  See '  -- Residual
Certificates -- Excess Inclusions' above. If the portfolio interest exemption is
unavailable, such amount will be subject  to United States withholding tax  when
paid  or otherwise distributed (or when the Residual Certificate is disposed of)
under  rules  similar  to  those  for  withholding  upon  disposition  of   debt
instruments  that have  OID. The Code,  however, grants  the Treasury Department
authority to  issue  regulations requiring  that  those amounts  be  taken  into
account  earlier than otherwise provided where necessary to prevent avoidance of
tax (for  example,  where the  Residual  Certificates do  not  have  significant
value).  See  ' --  Residual Certificates  -- Excess  Inclusions' above.  If the
amounts paid  to  Residual Certificateholders  that  are not  U.S.  persons  are
effectively  connected  with their  conduct of  a trade  or business  within the
United States,  the 30%  (or  lower treaty  rate)  withholding will  not  apply.
Instead,  the amounts  paid to  such non-U.S.  Person will  be subject  to U. S.
federal income taxation at regular graduated rates. For special restrictions  on
the  transfer of  Residual Certificates,  see '  -- Tax-Related  Restrictions on
Transfers of Residual Certificates' below.

     Regular Certificateholders and persons related  to such holders should  not
acquire  any Residual Certificates, and  Residual Certificateholders and persons
related  to  Residual   Certificateholders  should  not   acquire  any   Regular
Certificates,  without consulting their tax advisors  as to the possible adverse
tax consequences of such acquisition.
 
TAX-RELATED RESTRICTIONS ON TRANSFERS OF RESIDUAL CERTIFICATES
 
     Disqualified Organizations.  An  entity may not qualify  as a REMIC  unless
there  are reasonable arrangements designed to ensure that residual interests in
such entity are  not held  by 'disqualified organizations'  (as defined  below).
Further, a tax is imposed on the transfer of a residual interest in a REMIC to a
'disqualified  organization.' The amount of the tax equals the product of (A) an
amount (as determined under the REMIC Regulations) equal to the present value of
the total  anticipated 'excess  inclusions' with  respect to  such interest  for
periods  after the transfer and (B) the highest marginal federal income tax rate
applicable to corporations.  The tax  is imposed  on the  transferor unless  the
transfer  is through  an agent  (including a  broker or  other middleman)  for a
disqualified organization, in which event the  tax is imposed on the agent.  The
person  otherwise liable for the tax shall  be relieved of liability for the tax
if the transferee furnished to such  person an affidavit that the transferee  is
not  a disqualified organization and,  at the time of  the transfer, such person
does not have  actual knowledge  that the  affidavit is  false. A  'disqualified
organization'  means (A) the  United States, any  State, possession or political
subdivision thereof, any foreign  government, any international organization  or
any  agency or instrumentality of any of  the foregoing (provided that such term
does not include  an instrumentality if  all its activities  are subject to  tax
and,  except for FHLMC, a majority of its  board of directors is not selected by
any such governmental agency), (B) any organization (other than certain farmers'
cooperatives)  generally   exempt  from   federal  income   taxes  unless   such
organization  is subject to  the tax on 'unrelated  business taxable income' and
(C) a rural electric or telephone cooperative.
 
     A tax is imposed  on a 'pass-through entity'  (as defined below) holding  a
residual  interest in  a REMIC  if at any  time during  the taxable  year of the
pass-through entity  a disqualified  organization  is the  record holder  of  an
interest  in such entity. The amount  of the tax is equal  to the product of (A)
the amount of excess inclusions for  the taxable year allocable to the  interest
held  by  the disqualified  organization and  (B)  the highest  marginal federal
income tax rate  applicable to corporations.  The pass-through entity  otherwise
liable for the tax, for any period during which the disqualified organization is
the  record holder of an interest in  such entity, will be relieved of liability
for the tax if  such record holder  furnishes to such  entity an affidavit  that
such  record holder is not a disqualified organization and, for such period, the
pass-through entity does not have actual knowledge that the affidavit is  false.
For  this  purpose, a  'pass-through entity'  means  (i) a  regulated investment
company, real estate investment trust or common trust fund, (ii) a  partnership,
trust  or estate and  (iii) certain cooperatives.  Except as may  be provided in
Treasury regulations not yet issued, any  person holding an interest in a  pass-
through  entity as a nominee for another will, with respect to such interest, be
treated as a pass-through entity. The tax on pass-through entities is  generally
effective for periods after March 31, 1988, except that in the case of regulated
investment  companies,  real estate  investment trusts,  common trust  funds and
publicly-traded partnerships the tax shall apply  only to taxable years of  such
entities  beginning after December  31, 1988. Under  proposed legislation, large
partnerships (generally with  250 or more  partners) will be  taxable on  excess
inclusion income as if all partners were disqualified organizations.
 
     In  order to comply  with these rules,  the Agreement will  provide that no
record or  beneficial  ownership  interest  in a  Residual  Certificate  may  be
purchased,  transferred  or sold,  directly or  indirectly, without  the express
written consent of  the Master  Servicer. The  Master Servicer  will grant  such
consent  to  a proposed  transfer  only if  it  receives the  following:  (i) an
affidavit from  the  proposed  transferee  to  the  effect  that  it  is  not  a
disqualified  organization and  is not acquiring  the Residual  Certificate as a
nominee or agent  for a  disqualified organization and  (ii) a  covenant by  the
proposed  transferee to  the effect  that the  proposed transferee  agrees to be
bound by and to  abide by the transfer  restrictions applicable to the  Residual
Certificate.
 
     Noneconomic  Residual Certificates.   The REMIC  Regulations disregard, for
federal income tax purposes, any transfer of a Noneconomic Residual  Certificate
to  a 'U.S.  Person,' as  defined in the  following section  of this discussion,
unless no significant  purpose of the  transfer is to  enable the transferor  to
impede  the assessment or collection of  tax. A Noneconomic Residual Certificate
is any Residual Certificate  (including a Residual  Certificate with a  positive
value  at issuance)  unless, at  the time of  transfer, taking  into account the
Prepayment Assumption and any required or  permitted clean up calls or  required
liquidation  provided  for  in  the REMIC's  organizational  documents,  (i) the
present value of the expected  future distributions on the Residual  Certificate
at
 
                                       75
 

<PAGE>
<PAGE>

least  equals  the  product  of  the present  value  of  the  anticipated excess
inclusions and the highest corporate income tax  rate in effect for the year  in
which  the transfer occurs  and (ii) the transferor  reasonably expects that the
transferee will receive  distributions from the  REMIC at or  after the time  at
which  taxes accrue on the anticipated excess inclusions in an amount sufficient
to satisfy the accrued taxes. A significant purpose to impede the assessment  or
collection  of tax exists if the transferor, at the time of the transfer, either
knew or should have known  that the transferee would  be unwilling or unable  to
pay  taxes due on its share of the  taxable income of the REMIC. A transferor is
presumed not to have such knowledge if (i) the transferor conducted a reasonable
investigation of  the transferee  and (ii)  the transferee  acknowledges to  the
transferor  that the residual interest may generate tax liabilities in excess of
the cash flow and the  transferee represents that it  intends to pay such  taxes
associated  with the residual  interest as they  become due. If  a transfer of a
Noneconomic Residual Certificate is  disregarded, the transferor would  continue
to  be treated as the owner of the Residual Certificate and would continue to be
subject to tax on its allocable portion of the net income of the REMIC.
 
     Foreign Investors.  The  REMIC Regulations provide that  the transfer of  a
Residual  Certificate that has a 'tax avoidance potential' to a 'foreign person'
will be disregarded for federal income tax purposes. This rule appears to  apply
to  a transferee  who is not  a U.S.  Person unless such  transferee's income in
respect of the Residual Certificate is effectively connected with the conduct of
a United States trade or  business. A Residual Certificate  is deemed to have  a
tax  avoidance  potential  unless,  at  the  time  of  transfer,  the transferor
reasonably expects that the REMIC will distribute to the transferee amounts that
will equal at least 30 percent of  each excess inclusion, and that such  amounts
will  be distributed at or  after the time the  excess inclusion accrues and not
later than the end of  the calendar year following the  year of accrual. If  the
non-U.S.  Person  transfers  the  Residual Certificate  to  a  U.S.  Person, the
transfer will be  disregarded, and the  foreign transferor will  continue to  be
treated  as the owner, if the transfer has the effect of allowing the transferor
to avoid  tax  on  accrued  excess  inclusions.  The  provisions  in  the  REMIC
Regulations regarding transfers of Residual Certificates that have tax avoidance
potential  to foreign  persons are  effective for  all transfers  after June 30,
1992. The Agreement will provide that no record or beneficial ownership interest
in a  Residual Certificate  may be  transferred, directly  or indirectly,  to  a
non-U.S.  Person unless such  person provides the Trustee  with a duly completed
I.R.S. Form 4224 and the Trustee consents to such transfer in writing.
 
     Any attempted transfer or pledge in violation of the transfer  restrictions
shall  be absolutely  null and void  and shall  vest no rights  in any purported
transferee. Investors in Residual Certificates are advised to consult their  own
tax  advisors with  respect to  transfers of  the Residual  Certificates and, in
addition, pass-through entities are  advised to consult  their own tax  advisors
with respect to any tax which may be imposed on a pass-through entity.
 
                            STATE TAX CONSIDERATIONS
 
     In  addition to the  federal income tax  consequences described in 'Certain
Federal Income  Tax Considerations,'  potential  investors should  consider  the
state  and  local income  tax consequences  of  the acquisition,  ownership, and
disposition of  the Certificates.  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 tax consequences of investments in the Certificates.
 
                              ERISA CONSIDERATIONS
 
     The following describes  certain considerations under  ERISA and the  Code,
which  apply  only  to  Certificates  of a  Series  that  are  not  divided into
subclasses. If Certificates are divided  into subclasses the related  Prospectus
Supplement  will contain information concerning considerations relating to ERISA
and the Code that are applicable to such Certificates.
 
     ERISA imposes requirements on employee benefit plans (and 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')
subject to ERISA and on persons who are fiduciaries with respect to such  Plans.
Generally, ERISA applies to investments made by 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
 
                                       76

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 Senior Certificates 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  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  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  prohibits a  broad range  of transactions
involving Plan  assets  and  persons  ('Parties  in  Interest')  having  certain
specified  relationships  to a  Plan and  imposes additional  prohibitions where
Parties in  Interest are  fiduciaries with  respect to  such Plan.  Because  the
Mortgage   Loans  may  be  deemed  Plan  assets  of  each  Plan  that  purchases
Certificates, an investment in the Certificates 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 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 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  that 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  certificates  that  represent
interests in a mortgage pool consisting of mortgage loans representing loans for
single  family  homes ('Single  Family Certificates')  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 Certificates 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 twenty-five percent (25%)
of all Single Family Certificates and at least fifty percent (50%) of all Single
Family  Certificates are purchased by persons independent of the pool sponsor or
pool trustee. PTE 83-1 does not provide an exemption for transactions  involving
Subordinated Certificates. Accordingly, unless otherwise provided in the related
Prospectus  Supplement, no transfer of a Subordinated Certificate may be made to
a Plan.
 
     The discussion in this  and the next succeeding  paragraph applies only  to
Single  Family Certificates.  The Depositor believes  that, for  purposes of PTE
83-1,  the  term   'mortgage  pass-through  certificate'   would  include:   (i)
Certificates   issued  in  a  Series  consisting  of  only  a  single  class  of
Certificates; and (ii) Senior Certificates issued in a Series in which there  is
only  one class  of Senior Certificates;  provided that the  Certificates in the
case of clause  (i), or  the Senior  Certificates in  the case  of clause  (ii),
evidence  the  beneficial ownership  of both  a  specified percentage  of future
interest payments (greater than  zero percent (0%))  and a specified  percentage
(greater  than zero  percent(0%)) of future  principal payments  on the Mortgage
Loans. It  is not  clear whether  a  class of  Certificates that  evidences  the
beneficial  ownership  in  a  Trust  Fund  divided  into  mortgage  loan groups,
beneficial ownership  of a  specified percentage  of interest  payments only  or
principal  payments only, or  a notional amount of  either principal or interest
payments,  or  a  class  of   Certificates  entitled  to  receive  payments   of
 
                                       77

<PAGE>

interest  and  principal on  the  Mortgage Loans  only  after payments  to other
classes or after the occurrence of certain specified events would be a 'mortgage
pass-through certificate' for purposes of 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 certificateholders 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  (1%) 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  benefit,  to not  more  than adequate  consideration for
selling the mortgage loans plus reasonable compensation for services provided by
the pool sponsor  to the mortgage  pool. The Depositor  believes that the  first
general  condition  referred to  above  will be  satisfied  with respect  to the
Certificates in a Series issued without  a subordination feature, or the  Senior
Certificates only in a Series issued with a subordination feature, provided that
the  subordination and Reserve Fund, subordination by shifting of interests, the
pool insurance  or  other form  of  credit enhancement  described  herein  (such
subordination,  pool insurance  or other  form of  credit enhancement  being the
system of insurance  or other protection  referred to above)  with respect to  a
Series  of Certificates is maintained in an  amount not less than the greater of
one percent of  the aggregate  principal balance of  the Mortgage  Loans or  the
principal  balance  of  the  largest  Mortgage  Loan.  See  'Description  of the
Certificates' herein. In the absence of a ruling that the system of insurance or
other protection with respect  to a Series of  Certificates satisfies the  first
general  condition  referred to  above,  there can  be  no assurance  that these
features will be so viewed by 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 Certificates
must make  its own  determination as  to  whether the  first and  third  general
conditions,  and  the specific  conditions  described briefly  in  the preceding
paragraph, of 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 Certificates  is appropriate for the
Plan, taking into  account the  overall investment policy  of the  Plan and  the
composition of the Plan's investment portfolio.
 
     The  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 the following:
 
          (1)  the  acquisition  of  the  certificates by  a  Plan  is  on terms
     (including the price for the certificates)  that are at least as  favorable
     to  the  Plan as  they  would be  in an  arm's  length transaction  with an
     unrelated party;
 
          (2) the rights and interest evidenced by the certificates acquired  by
     the  Plan are  not subordinated  to the  rights and  interests evidenced by
     other certificates of the trust fund;
 
          (3) the certificates required  by the Plan have  received a rating  at
     the  time of  such acquisition  that is  one of  the three  highest generic
     rating categories  from Standard  &  Poor's Ratings  Group, a  division  of
     McGraw-Hill,  Inc.  ('S&P'), Moody's  Investors Service,  Inc. ('Moody's'),
     Duff & Phelps Credit  Rating Co. ('D&P') or  Fitch Investors Service,  Inc.
     ('Fitch');
 
          (4)  the trustee must not  be an affiliate of  any other member of the
     Restricted Group;
 
          (5) the sum of all payments  made to and retained by the  underwriters
     in connection with the distribution of the certificates represents not more
     than  reasonable compensation for underwriting the certificates; the sum of
     all payments made to and retained by the seller pursuant to the  assignment
     of  the loans to  the trust fund  represents not more  than the fair market
     value of such loans; the  sum of all payments made  to and retained by  the
     servicer  and  any  other  servicer  represents  not  more  than reasonable
     compensation for such  person's services  under the  agreement pursuant  to
     which  the loans are pooled and  reimbursements of such person's reasonable
     expenses in connection therewith; and
 
          (6) the Plan investing in the certificates is an 'accredited investor'
     as defined in Rule 501(a)(1) of Regulation D of the Securities and Exchange
     Commission under the Securities Act of 1933 as amended.
 
                                       78

     The trust fund must also meet the following requirements:
 
          (i) the corpus of the trust fund must consist solely of assets of  the
     type that have been included in other investment pools;
 
          (ii)  certificates in such other investment pools must have been rated
     in one of the three highest rating categories of S&P, Moody's, Fitch or D&P
     for at least one year prior to the Plan's acquisition of certificates; and
 
          (iii) certificates evidencing interests in such other investment pools
     must have been  purchased by investors  other than Plans  for at least  one
     year prior to any Plan's acquisition of certificates.
 
     Moreover,  the Underwriter Exemptions generally provide relief from certain
self-dealing/conflict of interest  prohibited transactions that  may occur  when
the  Plan fiduciary causes a Plan to acquire certificates in a trust as to which
the fiduciary (or its affiliate)  is an obligor on  the receivables held in  the
trust provided that, among other requirements: (i) in the case of an acquisition
in  connection with the initial issuance of certificates, at least fifty percent
(50%) of each class of certificates in which Plans have invested is acquired  by
persons  independent  of  the  Restricted Group,  (ii)  such  fiduciary  (or its
affiliate) is an obligor with respect to  five percent (5%) or less of the  fair
market  value  of  the obligations  contained  in  the trust;  (iii)  the Plan's
investment in  certificates of  any class  does not  exceed twenty-five  percent
(25%)  of all of the  certificates of that class outstanding  at the time of the
acquisition;  and  (iv)  immediately  after   the  acquisition,  no  more   than
twenty-five  percent (25%) of the assets of  the Plan with respect to which such
person is a fiduciary  is invested in certificates  representing an interest  in
one  or more trusts containing  assets sold or serviced  by the same entity. The
Underwriter Exemptions  do not  apply  to Plans  sponsored  by the  Seller,  the
related  Underwriter, the Trustee, the Master Servicer, any insurer with respect
to the Mortgage Loans,  any obligor with respect  to Mortgage Loans included  in
the  Trust  Fund  constituting more  than  five  percent (5%)  of  the aggregate
unamortized principal balance of the assets in the Trust Fund, or any  affiliate
of such parties.
 
     The Prospectus Supplement for each Series of Certificates will indicate the
classes of Certificates, if any, offered thereby as to which it is expected that
an Underwriter Exemption will apply.
 
     Any  Plan fiduciary which proposes to cause a Plan to purchase Certificates
should consult with its counsel concerning the impact of ERISA and the Code, the
applicability of PTE 83-1, the availability and applicability of any Underwriter
Exemption or any other exemptions from the prohibited transaction provisions  of
ERISA   and  the  Code   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 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.
 
                                LEGAL INVESTMENT
 
     The Prospectus  Supplement for  each Series  of Certificates  will  specify
which,  if any, of  the classes of Certificates  offered thereby will constitute
'mortgage related securities'  for purposes  of SMMEA.  Classes of  Certificates
that  qualify as  'mortgage related  securities' will  be legal  investments for
persons, trusts, corporations, partnerships,  associations, business trusts  and
business  entities (including depository  institutions, life insurance companies
and pension funds) created pursuant to or existing under the laws of the  United
States  or of  any state  (including the District  of Columbia  and Puerto Rico)
whose authorized investments are subject to state regulation to the same  extent
as,  under applicable law,  obligations issued by or  guaranteed as to principal
and interest by the United States or any such entities. Under SMMEA, if a  state
enacts  legislation prior  to October  4, 1991  specifically limiting  the legal
investment authority  of any  such entities  with respect  to 'mortgage  related
securities,'  the Certificates  will constitute  legal investments  for entities
subject to such legislation only  to the extent provided therein.  Approximately
twenty-one  states  adopted  such  legislation  prior  to  the  October  4, 1991
deadline. SMMEA provides, however,  that in no event  will the enactment of  any
such  legislation affect the validity of any contractual commitment to purchase,
hold or invest  in Certificates,  or require the  sale or  other disposition  of
Certificates,   so  long  as  such  contractual  commitment  was  made  or  such
Certificates acquired prior to the enactment of such legislation.
 
     SMMEA also amended  the legal investment  authority of  federally-chartered
depository  institutions as follows:  federal savings and  loan associations and
federal savings banks  may invest  in, sell  or otherwise  deal in  Certificates
without  limitations as to  the percentage of  their assets represented thereby,
federal credit unions may  invest in mortgage  related securities, and  national
banks    may   purchase    Certificates   for   their    own   account   without
 
                                       79

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), (whether  or not  the class  of
Certificates  under consideration  for purchase constitutes  a 'mortgage related
security').
 
     All depository institutions considering  an investment in the  Certificates
(whether  or  not the  class of  certificates  under consideration  for purchase
constitutes a 'mortgage  related security' should  review the Federal  Financial
Institutions  Examination Council's  Supervisory Policy  Statement on 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' that are 'high-risk mortgage securities'
as  defined in  the Policy  Statement. According  to the  Policy Statement, such
'high-risk mortgage  securities' include  securities  such as  Certificates  not
entitled  to distributions allocated  to principal or  interest, or Subordinated
Certificates. Under  the Policy  Statement,  it is  the responsibility  of  each
depository  institution to determine, prior to purchase (and at stated intervals
thereafter), whether a  particular mortgage derivative  product is a  'high-risk
mortgage  security', and whether  the purchase (or retention)  of such a product
would be consistent with the Policy Statement.
 
     The foregoing  does  not  take  into  consideration  the  applicability  of
statutes,  rules,  regulations,  orders,  guidelines,  or  agreements  generally
governing investments made by a particular investor, including, but not  limited
to,  'prudent investor'  provisions, percentage-of-assets  limits and provisions
that may restrict or  prohibit investment in securities  that are not  'interest
bearing' or 'income paying.'
 
     There  may  be  other restrictions  on  the ability  of  certain investors,
including  depository  institutions,  either  to  purchase  Certificates  or  to
purchase  Certificates  representing more  than  a specified  percentage  of the
investor's  assets.  Investors  should  consult  their  own  legal  advisors  in
determining  whether  and  to  what  extent  the  Certificates  constitute legal
investments for such investors.
 
                             METHOD OF DISTRIBUTION
 
     Certificates are being  offered hereby in  Series from time  to time  (each
Series evidencing a separate Trust Fund) through any of the following methods:
 
          1. By negotiated firm commitment underwriting and public reoffering by
     underwriters;
 
          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 Certificates  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 Certificates  so offered.  In firm commitment
underwritten offerings, the underwriters  will be obligated  to purchase all  of
the  Certificates  of  such  Series  if  any  such  Certificates  are purchased.
Certificates may be acquired by the underwriters for their own accounts and  may
be  resold from time to  time in one or  more transactions, including negotiated
transactions, at a fixed public offering  price or at varying prices  determined
at the time of sale.
 
     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.
 
                                       80
 

<PAGE>
<PAGE>

     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 Certificates of such Series.
 
                                 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, One World Trade Center, New York, New York 10048.
 
                             FINANCIAL INFORMATION
 
     A new Trust Fund will be formed with respect to each Series of Certificates
and  no Trust Fund will engage in any  business activities or have any assets or
obligations prior  to  the  issuance  of the  related  Series  of  Certificates.
Accordingly,  no financial  statements with  respect to  any Trust  Fund will be
included in this Prospectus or in the related Prospectus Supplement.
 
                                     RATING
 
     It is  a condition  to the  issuance  of the  Certificates of  each  Series
offered  hereby and by the Prospectus Supplement that they shall have been rated
in one  of the  four  highest rating  categories  by the  nationally  recognized
statistical  rating  agency  or  agencies specified  in  the  related Prospectus
Supplement.
 
     Ratings on  mortgage pass-through  certificates address  the likelihood  of
receipt  by certificateholders of  all distributions on  the underlying mortgage
loans. These ratings  address the structural,  legal and issuer-related  aspects
associated  with such certificates, the nature  of the underlying mortgage loans
and the credit quality of the credit  enhancer or guarantor, if any. Ratings  on
mortgage  pass-through  certificates  do  not represent  any  assessment  of the
likelihood of principal prepayments by mortgagors or of the degree by which such
prepayments might  differ  from  those  originally  anticipated.  As  a  result,
certificateholders  might  suffer  a  lower  than  anticipated  yield,  and,  in
addition, holders of stripped pass-through  certificates in extreme cases  might
fail to recoup their underlying investments.
 
     A  security rating is not a recommendation  to buy, sell or hold securities
and may be subject to revision or withdrawal at any time by the assigning rating
organization. Each  security rating  should be  evaluated independently  of  any
other security rating.
