(1) Subject to the permitted variance described herein.
(2) The Class A-4 and Class A-5 Certificates will bear interest based on 'LIBOR'
    as described under 'Description of the Certificates -- Interest' herein.
(3) The Class A-5 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 $31,059,000  and
    $124,088,814, respectively).
(4) The  Class PO Certificates will be  Principal Only Certificates and will not
    bear interest.
(5) 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 Net  Mortgage
    Rates  of  the Non-Discount  Mortgage Loans  over (b)  7.75% per  annum. The
    Pass-Through Rate for the  Class X Certificates  for the first  Distribution
    Date is expected to be approximately 0.5029% per annum.

     The  Senior Certificates, other than the  Class PO and Class X Certificates
(the 'Underwritten Senior Certificates'), and the Class B-1, Class B-2 and Class
B-3 Certificates  (together  with  the  Underwritten  Senior  Certificates,  the
'Underwritten  Certificates')  offered  hereby  will  be  purchased  by  Salomon
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. Proceeds to the Depositor from the
sale  of  the  Underwritten  Certificates  are  expected  to  be   approximately
$156,924,000,  plus accrued interest, before deducting issuance expenses payable
by the Depositor. The Class  PO and Class X Certificates  will be issued to  the
Depositor on or about July 30, 1996 as partial consideration for the sale of the
Mortgage Loans to the Trust Fund.

     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 their 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 Salomon Brothers Inc in  New York, New York, on or about July
30, 1996.

     The Mortgage Loans will be sold to the Depositor by Countrywide Home Loans,
Inc. (formerly known as Countrywide Funding Corporation) ('Countrywide').
 
     For federal income tax purposes, the Trust Fund will include two segregated
asset pools, with respect  to which elections  will be made to  treat each as  a
'real  estate mortgage investment conduit' (a  'REMIC'). See 'Description of the
Certificates -- Separate REMIC Structure' herein. As described more fully herein
and in the Prospectus, the Certificates, other than the Class A-R  Certificates,
will be designated as the 'regular interests' in the Master REMIC. The Class A-R
Certificates   will  constitute  the  beneficial   ownership  of  the  'residual
interests' in  both  the Master  REMIC  and the  Subsidiary  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.'
 
     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 ON THE MORTGAGE LOANS 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 INTEREST  ONLY
CERTIFICATES, THE RISK THAT A FASTER THAN ANTICIPATED RATE OF PRINCIPAL PAYMENTS
ON  THE MORTGAGE LOANS  COULD RESULT IN AN  ACTUAL YIELD THAT  IS LOWER THAN THE
ANTICIPATED YIELD. HOLDERS  OF THE INTEREST  ONLY 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  YIELD  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
AS TO THE RESULTING YIELD TO MATURITY OF ANY CLASS OF CERTIFICATES.
 
     THE  YIELDS ON  THE LIBOR  CERTIFICATES WILL BE  SENSITIVE TO  THE LEVEL OF
LIBOR (DETERMINED AS DESCRIBED HEREIN).
 
     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

EFFECTING TRANSACTIONS IN THE OFFERED CERTIFICATES, WHETHER OR NOT PARTICIPATING
IN THIS DISTRIBUTION, MAY BE REQUIRED TO DELIVER A PROSPECTUS SUPPLEMENT AND THE

                                         occurs.
 
  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

                                         Each  Class of  LIBOR Certificates will  bear interest  during its initial
                                         Interest Accrual Period at the initial Pass-Through Rate set forth  below,
                                         and  will bear  interest during  each Interest  Accrual Period thereafter,

                                         first Distribution Date is expected to be approximately 0.5029% per annum.
 
Distributions of Principal.............  On  each Distribution  Date, to the  extent funds  are available therefor,
                                         principal distributions in reduction of the Class Certificate Balances  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  A-9/Class  A-10  Principal Distribution
                                         Amount, the Class  PO Principal  Distribution Amount  or the  Subordinated
                                         Principal   Distribution  Amount,  as   applicable.  The  Notional  Amount
                                         Certificates do not have  principal balances and are  not entitled to  any
                                         distributions   in  respect  of  principal  of  the  Mortgage  Loans.  See
                                         'Description of the Certificates -- Principal' herein.
 
Credit Enhancement -- General..........  Credit enhancement for  the Senior  Certificates will be  provided by  the
                                         Subordinated  Certificates  and  credit  enhancement  for  each  Class  of
                                         Subordinated 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 $1,790,932.
 
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 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  Class  or  Classes  of
                                         Subordinated Certificates with lower numerical Class designations, in each
                                         case only to the extent described herein.
 
                                         The  subordination  of  the   Subordinated  Certificates  to  the   Senior
                                         Certificates,  and  the  further  subordination  within  the  Subordinated
                                         Certificates, is intended to 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 on  the 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 the Senior Certificates will
                                         bear their  proportionate share  of any  losses realized  on the  Mortgage
                                         Loans  in excess of the available  subordination amount, provided, that on
                                         and after  the  Senior Credit  Support  Depletion Date,  Realized  Losses,
                                         including Excess Losses, otherwise allocable to the Class A-6 or Class A-8
                                         Certificates  will be allocated  to the Class  A-10 Certificates until the
                                         Class  Certificate  Balance  thereof  has   been  reduced  to  zero.   See
                                         'Description  of  the  Certificates  --  Priority  of  Distributions Among
                                         Certificates,'   '    --    Allocation    of    Losses,'    and    'Credit

Advances...............................  The  Master Servicer is obligated to  make cash advances ('Advances') with
                                         respect to  delinquent  payments  of  principal of  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

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 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  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  Interest Only Certificates and any other  Offered
                                         Certificate  purchased at  a premium,  a faster  than anticipated  rate of
                                         principal payments could result in an  actual yield to such investor  that
                                         is  lower  than  the anticipated  yield.  Investors in  the  Interest Only
                                         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......  For  federal  income  tax  purposes,  the  Trust  Fund  will  include  two
                                         segregated asset pools, with  respect to which elections  will be made  to
                                         treat  each  as  a  separate  'real  estate  mortgage  investment conduit'
                                         ('REMIC'). The Regular Certificates will constitute 'regular interests' in
                                         the Master REMIC. The Class A-R Certificates will represent the beneficial
                                         ownership of the sole class of 'residual interest' in the Master REMIC and
                                         the sole class of  residual interest in the  Subsidiary REMIC and will  be
                                         the class of Residual Certificates, as described in the Prospectus.
 
                                         The  Interest Only Certificates and  the Principal Only Certificates will,
                                         and certain  other Classes  of Offered  Certificates may,  be issued  with
                                         original  issue  discount for  federal income  tax purposes.  See 'Certain
                                         Federal Income Tax Consequences' herein and in the Prospectus.
 
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

                                         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
                                         Certificates  complies  with applicable  guidelines, policy  statements or
                                         restrictions. See 'Legal Investment' in the Prospectus.
 
Ratings................................  It is a condition to the issuance of the Senior Certificates that they  be
                                         rated  AAA by Fitch Investors Service,  L.P. ('Fitch') and, other than the
                                         Class A-5, Class  PO and Class  X Certificates, AAA  by Standard &  Poor's
                                         Ratings Group ('S&P' and, together with Fitch, the 'Rating Agencies'). The
                                         Class  A-5, Class PO and  Class X Certificates will  be rated AAAr by S&P.
                                         See 'Ratings' herein. 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
                                         either of the Rating Agencies. See 'Ratings' herein.

                               THE MORTGAGE POOL
 
GENERAL
 
     The Depositor will purchase the Mortgage Loans from Countrywide pursuant to
the  Pooling  and  Servicing  Agreement  dated  as  of  the  Cut-off  Date among
Countrywide, 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 the 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  the 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 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. Countrywide
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
obligation described above. The obligations of Countrywide, 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 expected  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  herein 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 $162,688,276 (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 the Mortgage  Loans provide for  payments due as  of the first  day of  each
month  (the 'Due Date'). 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.  The
Mortgagors may prepay their Mortgage Loans at any time without penalty.
 

     Each Mortgage Loan was originated after April 1, 1992.

 
     The latest stated maturity date of any Mortgage Loan is August 1, 2026. The
earliest stated maturity date of any Mortgage Loan is May 1, 2016.
 
     As of the Cut-off Date, no Mortgage Loan was delinquent more than 30 days.
 
     No  more  than  8  of the  Mortgage  Loans  will be  subject  to  a buydown
agreement.  No  Mortgage  Loan  provides  for  deferred  interest  or   negative
amortization.
 
     As  of the Cut-off Date, 4 Mortgage Loans, representing approximately 0.58%
of the Cut-off Date Pool Principal  Balance, were originated as adjustable  rate
mortgage  loans  but  converted to  fixed  rate  Mortgage Loans  prior  to their
inclusion in the Mortgage Pool.
 
     No Mortgage Loan had a Loan-to-Value Ratio at origination of more than 95%.
Each Mortgage Loan with a Loan-to-Value Ratio at origination of greater than 80%
is covered by a primary mortgage guaranty insurance
 
                                      S-9

<PAGE>
policy issued by a mortgage insurance company acceptable to the Federal National
Mortgage Association  ('FNMA') or  the Federal  Home Loan  Mortgage  Corporation
('FHLMC'),  which policy provides coverage  in an amount equal  to the excess of
the original principal  balance of  the related Mortgage  Loan over  75% of  the
value  of  the related  Mortgaged Property,  plus  accrued interest  thereon and
related  foreclosure  expenses.   With  respect  to   33  Mortgage  Loans   with
Loan-to-Value Ratios at origination of greater than 80%, the lender (rather than
the  borrower) acquired the primary mortgage  guaranty insurance and charged the
related borrower an  interest premium equal  to the lender's  cost of  obtaining
such  insurance (such Mortgage  Loans, the 'Lender  PMI Mortgage Loans'). Except
with respect to the Lender PMI Mortgage Loans, 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. With respect to the Lender PMI Mortgage Loans,
the primary mortgage guaranty insurance policy  will be maintained for the  life
of such Mortgage Loans.
 
     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 or its  appraised value at the time of sale,  or
(b) in the case of a refinance, the appraised value of the Mortgaged Property at
the  time of such refinance, except in  the case of a Mortgage Loan underwritten
pursuant to  Countrywide's  Streamlined  Refinance  Documentation  Program  (the
'Streamlined Documentation Program') as described herein under ' -- Underwriting
Standards.'   With  respect  to  Mortgage   Loans  originated  pursuant  to  the
Streamlined Documentation Program (a) if the loan-to-value ratio at the time  of
the  origination of  the mortgage  loan being  refinanced was  60% or  less, the
'Loan-to-Value Ratio' will be the ratio of the principal amount of the  Mortgage
Loan  outstanding at the date of determination divided by the appraised value of
the related mortgaged property  at the time of  the origination of the  mortgage
loan  being refinanced  or (b)  if the  loan-to-value ratio  at the  time of the
origination of the mortgage loan being refinanced was greater than 60%, then the
'Loan-to-Value Ratio' will be the ratio of the principal amount of the  Mortgage
Loan  outstanding at the date of determination divided by the appraised value as
determined by an appraisal at the time of the origination of such Mortgage Loan.
See ' --  Underwriting Standards'  herein. 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%.

'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  documents 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
interests 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 Trustee to the effect that such substitution will not
disqualify the REMIC or result in  a prohibited transaction tax under the  Code.
Any Replacement Mortgage Loan generally will, on the date of substitution, among
other  characteristics set forth in the Agreement, (i) have a principal balance,
after deduction of all Scheduled Payments due in the month of substitution,  not
in  excess of, and not more than 10%  less than, the Stated Principal Balance of
the Deleted Mortgage Loan (the  amount of any shortfall  to be deposited by  the
Seller   in  the   Certificate  Account  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
 
     All mortgage loans must meet  credit, appraisal and underwriting  standards
acceptable  to Countrywide. Such 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.
Such  underwriting  procedures are  generally  consistent with  those identified
under 'Mortgage Loan Program -- Underwriting Standards' in the Prospectus except
as otherwise provided herein.
 
     Each  prospective  mortgagor  completes   an  application  which   includes
information  with respect to the applicant's assets, liabilities, income, credit
history, employment history  and other personal  information. In addition,  each
applicant  is required to have sufficient  cash resources to pay the downpayment
and closing costs. Countrywide requires a credit report on each applicant from a
credit reporting company. The report typically contains information relating  to
such  matters as credit  history with local and  national merchants and lenders,
 
                                      S-13
 
<PAGE>
<PAGE>
installment debt payments and any record of defaults, bankruptcy, dispossession,
suits or judgments. All adverse information in the credit report is required  to
be  explained by  the prospective  borrower to  the satisfaction  of the lending
officer. Self-employed individuals  are generally required  to submit their  two
most  recent federal  income tax returns.  In determining  whether a prospective
borrower has  sufficient monthly  income available  (i) to  meet the  borrower's
monthly  obligations relating to the  proposed mortgage loan (including property
taxes,  hazard  insurance  premiums,  and  where  applicable,  primary  mortgage
guaranty  insurance premiums and homeowners' association  dues) and (ii) to meet
monthly housing  expenses described  in  clause (i)  above and  other  financial
obligations   of  the  borrower  (including   consumer  and  installment  debt),
Countrywide generally applies ratios with  respect to fixed rate mortgage  loans
of up to 33% and 38%, respectively, of the proposed borrower's acceptable stable
monthly  gross income. Exceptions to the underwriting standards described herein
are made in certain circumstances where compensating factors are demonstrated by
a prospective borrower.
 
     Except as described  below with  respect to  its Streamlined  Documentation
Program,  Countrywide's  underwriting  standards  generally  allow Loan-to-Value
Ratios at origination of  up to 95% for  mortgage loans with original  principal
balances of up to $300,000, up to 90% for mortgage loans with original principal
balances of up to $400,000, up to 80% for mortgage loans with original principal
balances of up to $500,000, up to 75% for Mortgage Loans with original principal
balances of up to $650,000, up to 70% for mortgage loans with original principal
balances  of  up to  $750,000 and  up to  60% for  mortgage loans  with original
principal balances of up to $1,000,000. Countrywide generally does not originate
cash-out refinance mortgage loans with original principal balances in excess  of
$650,000.  A  refinance  mortgage loan  is  classified as  a  cash-out refinance
mortgage loan by Countrywide  if the borrower retains  greater than 1.0% of  the
entire  amount of  the proceeds  from the  refinancing of  the existing mortgage
loan.
 
     Except as described  below with  respect to  its Streamlined  Documentation
Program, Countrywide obtains appraisals from independent appraisers or appraisal
services  for  properties that  are to  secure  mortgage loans.  Such appraisers
inspect and appraise the  subject property and verify  that such property is  in
acceptable  condition. Following each appraisal, the appraiser prepares a report
which includes a market data analysis based on recent sales of comparable  homes
in  the area and, when deemed appropriate,  a replacement cost analysis based on
the current cost of constructing a similar home. All appraisals are required  to
conform  to FNMA or FHLMC appraisal  standards then in effect. Every independent
appraisal is reviewed by a Countrywide underwriter before the loan is funded.
 
     Countrywide requires title insurance on  all of its mortgage loans  secured
by  liens on  real property.  Countrywide also  requires that  fire and extended
coverage casualty insurance be maintained on  the secured property in an  amount
at least equal to the principal balance of the related single-family loan or the
replacement cost of the property, whichever is less.
 
     Countrywide   also  originates  or  acquires  mortgage  loans  pursuant  to
alternative sets of  underwriting criteria under  its Alternative  Documentation
Loan   Program   (the   'Alternative   Documentation   Program'),   its  Reduced
Documentation  Loan  Program  (the  'Reduced  Documentation  Program')  and  its
Streamlined Documentation Program. The Alternative Documentation Program permits
a  borrower to provide W-2 forms instead of tax returns covering the most recent
two years, permits  bank statements  in lieu  of verifications  of deposits  and
permits  alternative  methods  of  employment  verification.  Under  the Reduced
Documentation  Program,  relatively   more  emphasis  is   placed  on   property
underwriting  than  on  credit  underwriting  and  certain  credit  underwriting
documentation concerning income and employment verification therefore is waived.
However, under  the  Reduced  Documentation Program,  Countrywide  obtains  from
prospective  borrowers either a verification of  deposits or bank statements for
the most recent two-month period preceding the loan application. Mortgage  loans
underwritten  under the Reduced  Documentation Program generally  are limited to
self-employed borrowers with  credit histories that  demonstrate an  established
ability   to  repay  indebtedness   in  a  timely   fashion.  Permitted  maximum
Loan-to-Value  Ratios  (including   secondary  financing)   under  the   Reduced
Documentation  Program, which range  up to 70%, are  more restrictive than under
Countrywide's  standard  underwriting  criteria.  Mortgage  loans   underwritten
pursuant  to  the Reduced  Documentation Program  generally  must be  secured by
owner-occupied primary residences. The Streamlined Documentation Program  allows
a  borrower to  refinance an existing  Countrywide mortgage  loan provided that,
among other things, such mortgage loan has not been more than 30 days delinquent
in payment  during  the  previous twelve-month  period.  Under  the  Streamlined
Documentation Program, appraisals are obtained only if the loan being refinanced
had  a  loan-to-value ratio  at the  time of  origination in  excess of  60%. In
addition,   under   the    Streamlined   Documentation    Program,   a    credit
 
                                      S-14
 
<PAGE>
<PAGE>
report  is obtained but only a limited  credit review is conducted, no income or
asset verification is  required, and  telephonic verification  of employment  is
permitted.   Permitted  maximum  Loan-to-Value   Ratios  under  the  Streamlined
Documentation Program range up to 100%.
 
     Countrywide does not maintain separate records regarding the delinquency or
foreclosure rates of mortgage  loans underwritten under  any of the  Alternative
Documentation  Program,  the Reduced  Documentation  Program or  the Streamlined
Documentation Program, as  compared to mortgage  loans underwritten pursuant  to
its  standard underwriting criteria. However,  Countrywide does not believe that
there are material differences regarding  the delinquency and foreclosure  rates
of  mortgage loans underwritten under the Alternative Documentation Program, the
Reduced Documentation  Program  and  the Streamlined  Documentation  Program  as
compared   to  mortgage  loans  underwritten  under  its  standard  underwriting
criteria.
 
                          SERVICING OF MORTGAGE LOANS
 
GENERAL
 
     The Master Servicer will service the Mortgage Loans in accordance with  the
terms  set forth in  the Agreement. The  Master Servicer may  perform any of its
obligations  under   the   Agreement   through   one   or   more   subservicers.
Notwithstanding  any  such subservicing  arrangement,  the Master  Servicer will
remain liable for its servicing duties and obligations under the Agreement as if
the Master Servicer alone were servicing the Mortgage Loans.
 
THE MASTER SERVICER
 
     Countrywide  Home  Loans,  Inc.  (formerly  known  as  Countrywide  Funding
Corporation)  ('Countrywide'),  a  New  York  corporation  and  a  subsidiary of
Countrywide Credit  Industries,  Inc.,  will  act as  Master  Servicer  for  the
Mortgage  Loans pursuant to  the Agreement. Countrywide  is engaged primarily in
the mortgage banking  business, and  as such, originates,  purchases, sells  and
services  mortgage loans. Countrywide originates mortgage loans through a retail
branch system and through mortgage  loan brokers and correspondents  nationwide.
Countrywide's  mortgage loans  are principally  first-lien, fixed  or adjustable
rate mortgage loans secured by single-family residences.
 

     At June 30, 1996, Countrywide  provided servicing for approximately  $145.6
billion aggregate principal amount of mortgage loans, substantially all of which
are being serviced for unaffiliated persons.

 
     The  principal executive  offices of Countrywide  are located  at 155 North
Lake Avenue, Pasadena, California 91101-7139.
 
     Countrywide initially services substantially all  of the mortgage loans  it
originates  or  acquires.  In  addition,  Countrywide  maintains  a  program  of
purchasing in bulk  the rights  to service  mortgage loans  originated by  other
lenders.  Servicing includes collecting and  remitting loan payments, accounting
for principal and interest, holding escrow (impound) funds for payment of  taxes
and  insurance,  making  inspections  as  required  of  the  mortgaged premises,
contacting delinquent  mortgagors,  supervising  foreclosures in  the  event  of
unremedied defaults and generally administering the loans, for which Countrywide
receives  servicing fees. Countrywide has in the past and may in the future sell
to other mortgage bankers a portion  of its portfolio of loan servicing  rights.
In  addition,  see  'The  Pooling  and Servicing  Agreement  --  Evidence  as to
Compliance' in the Prospectus for a  description of the annual servicing  report
and  the report of the independent public accountants required to be provided by
Countrywide in its capacity as Master Servicer under the Agreement.

FORECLOSURE AND DELINQUENCY EXPERIENCE
 
     Historically, a  variety of  factors, including  the appreciation  of  real
estate   values,  have  limited  the  Master  Servicer's  loss  and  delinquency
experience on  its  portfolio  of  serviced mortgage  loans.  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.
 
     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 security 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.
 

     The following table summarizes the delinquency and foreclosure  experience,
respectively, on the dates indicated, of conventional mortgage loans serviced or
master  serviced  by  the  Master  Servicer.  The  delinquency  and  foreclosure
percentages may be affected by  the size and relative  lack of seasoning of  the
servicing portfolio which increased from approximately $54.4 billion at February
28,  1993 to approximately $84.6 billion  at February 28, 1994, to approximately
$113.1 billion at February 28, 1995 to approximately $136.8 billion at  February
29,  1996 and to approximately $145.6 billion at June 30, 1996. Accordingly, the
information should not be  considered as a basis  for assessing the  likelihood,
amount  or  severity of  delinquency  or losses  on  the Mortgage  Loans  and no
assurances  can  be  given  that  the  foreclosure  and  delinquency  experience
presented  in  the table  below will  be  indicative of  such experience  on the
Mortgage Loans:

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  be 0.259% per
annum of the Stated  Principal Balance of each  Mortgage Loan. The Expense  Fees
consist  of (a) servicing compensation payable to the Master Servicer in respect
of its master  servicing activities (the  'Master Servicing Fee')  and (b)  fees
payable  to  the Trustee  in  respect of  its  activities as  trustee  under the
Agreement. The  Master Servicing  Fee will  be  0.25% per  annum of  the  Stated
Principal Balance of each Mortgage Loan. 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  is  also   entitled  to  receive,   as  additional  servicing
compensation, all late payment fees,  assumption fees and other similar  charges
and  all reinvestment  income earned  on amounts  on deposit  in the Certificate
Account and Distribution Account.  The Net Mortgage Rate  of a Mortgage Loan  is
the  Mortgage Rate thereof minus the Expense  Fees with respect to such Mortgage
Loan (expressed  as a  per  annum percentage  of  the Stated  Principal  Balance
thereof).
 
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. Except  with respect  to  the month  of the  Cut-off Date,
principal prepayments  by borrowers  received by  the Master  Servicer from  the
first  day through the fifteenth day of  a calendar month will be distributed to
Certificateholders on the  Distribution Date  in the  same month  in which  such
prepayments  are  received  and,  accordingly, no  shortfall  in  the  amount of
interest to be  distributed to  Certificateholders with respect  to the  prepaid
Mortgage  Loans results. Conversely, principal prepayments by borrowers received
by the Master  Servicer from the  sixteenth day (or,  in the case  of the  first
Distribution  Date, from the  Cut-off Date) through  the last day  of a calendar
month will be distributed to Certificateholders on the Distribution Date in  the
month following the month of receipt and, accordingly, a shortfall in the amount
of interest to be distributed to Certificateholders with respect to such prepaid
Mortgage Loans would result. Pursuant to the Agreement, the Master Servicing Fee
for  any month  will be reduced,  but not by  more than one-half  of such Master
Servicing Fee, by an amount sufficient to pass through to Certificateholders the
full amount of interest to which they would be entitled in respect of each  such
prepaid  Mortgage  Loan  on  the related  Distribution  Date.  If  shortfalls in
interest as a result  of prepayments in any  Prepayment Period exceed an  amount
equal  to one-half of the Master Servicing  Fee otherwise payable on the related
Distribution Date,  the  amount  of  interest available  to  be  distributed  to
Certificateholders   will  be  reduced  by  the   amount  of  such  excess.  See
'Description of the Certificates -- Interest' herein.
 
ADVANCES
 
     Subject to the following limitations, the Master Servicer will be  required
to  advance prior to each Distribution Date, from  its own funds or funds in the
Certificate Account that do not constitute Available Funds for such Distribution
Date, an amount equal to the aggregate of payments of principal and interest  on
the  Mortgage Loans (net of the Master 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.

                        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  1996-2 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  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  Subordinated
Certificates are collectively referred to herein as the 'Certificates.' Only the
Classes of  Certificates listed  on  the cover  page hereof  (collectively,  the
'Offered  Certificates') are offered hereby. The Classes of Offered Certificates
will have the respective initial Class Certificate Balances or initial  Notional
Amounts  (subject to the permitted variance) and Pass-Through Rates set forth 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 principal balances and are not entitled
to any distributions in respect of principal of the Mortgage Loans.
 
     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 Balance  of  the Non-Discount  Mortgage  Loans as  of  the
Cut-off Date.
 
     The Notional Amount of the Class A-5 Certificates for any Distribution Date
will  be equal to  the Class Certificate  Balance of the  Class A-4 Certificates
with respect to such Distribution Date.
 

     The Senior Certificates will have an initial aggregate principal balance of
approximately $153,333,344  and  will  evidence  in  the  aggregate  an  initial
beneficial  ownership interest  of approximately 94.25%  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 2.00%, 1.75%, 0.90%, 0.60%, 0.15%, and 0.35%, respectively, in the
Trust Fund.

 

     The  Book-Entry Certificates will be issuable  in book-entry form only. The
Physical Certificates will be issued in fully registered certificated form.  The
Class  A-R Certificates will be issued as a single Certificate in a denomination
of $100.

 
SEPARATE REMIC STRUCTURE
 
     For federal income tax purposes, the Trust Fund will include two segregated
asset pools, each of which  will be treated as a  separate REMIC. The assets  of
the Subsidiary REMIC will generally consist of the Mortgage Loans. The assets of
the  Master REMIC will generally consist of uncertified regular interests issued
by the  Subsidiary  REMIC,  which  in  the  aggregate  will  correspond  to  the
Certificates.
 
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
 
                                      S-18
 
<PAGE>
<PAGE>
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  in minimum  denominations
representing  an original principal amount of  $25,000 and integral multiples of
$1,000 in excess thereof. One investor of each Class of Book-Entry  Certificates
may  hold a  beneficial interest  therein that  is not  an integral  multiple of
$1,000. The Depositor has been informed by 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 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.
 
DETERMINATION OF LIBOR
 
     The  LIBOR Certificates  will bear  interest during  their initial Interest
Accrual Period at  the applicable  initial Pass-Through  Rate set  forth in  the
table  under  ' --  Interest'  below, and  during  each Interest  Accrual Period
thereafter at the  applicable rate determined  as described in  the table  under
' -- Interest' below.
 
     LIBOR  applicable to an  Interest Accrual Period will  be determined on the
second business day prior to the commencement of such Interest Accrual Period (a
'LIBOR Determination  Date'). On  each LIBOR  Determination Date  for the  LIBOR
Certificates,  the Trustee, as  Calculation Agent, will  establish LIBOR for the
related Interest Accrual Period in the manner described in the Prospectus  under
'Description  of the  Certificates --  Indices Applicable  to Floating  Rate and
Inverse Floating Rate Classes -- LIBOR.'
 
     If on  the  Initial LIBOR  Determination  Date, the  Calculation  Agent  is
required but unable to determine LIBOR in the manner provided in the Prospectus,
LIBOR for the next Interest Accrual Period will be 5.4375%.
 
PAYMENTS ON MORTGAGE LOANS; ACCOUNTS
 
     On  or prior  to the  Closing Date, the  Master Servicer  will establish an
account (the 'Certificate Account'), which will  be maintained in trust for  the
benefit of the Certificateholders. Funds credited to the Certificate 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. 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 and  will deposit  such  Available Funds  in  an account  established  and
maintained   with  the  Trustee   on  behalf  of   the  Certificateholders  (the
'Distribution Account').
 
DISTRIBUTIONS
 
     Distributions on the Certificates will be  made by the Trustee on the  25th
day  of each month, or if such day is  not a business day, on the first business
day thereafter, commencing in August 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  Certificates with  an  aggregate  initial
Certificate Balance of $1,000,000 or
 
                                      S-19

more  or who  holds an  Interest Only  Certificate 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 interest  on each  interest bearing  Class of  Senior Certificates;  (ii)  to
principal  on  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,' in  each case in  an aggregate amount  up to  the
maximum  amount  of  principal  to  be  distributed  on  such  Classes  on  such
Distribution Date; (iii) to  any Class PO Deferred  Amounts with respect to  the
Class PO Certificates, but only from amounts that would otherwise be distributed
on  such Distribution  Date as principal  of the  Subordinated Certificates; and
(iv)  to  interest  on  and  then  principal  of  each  Class  of   Subordinated
Certificates, in the order of their numerical Class designations, beginning with
the  Class B-1 Certificates, in  each case subject to  the limitations set forth
herein under 'Description of the Certificates -- 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  calendar 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 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 from the
Certificate Account pursuant to the Agreement.
 
INTEREST
 
     The Classes of Offered Certificates  will have the respective  Pass-Through
Rates set forth or described on the cover hereof.
 
     Each  of  the  LIBOR Certificates  will  bear interest  during  its initial
Interest Accrual Period at  the initial Pass-Through Rate  set forth below,  and
will  bear interest during  each Interest Accrual  Period thereafter, subject to
the applicable Maximum  and Minimum Pass-Through  Rates, at the  per annum  rate
determined by reference to LIBOR as described below:
 

<TABLE>
<CAPTION>
            INITIAL
             PASS-            MAXIMUM/MINIMUM        FORMULA FOR CALCULATION OF
CLASS     THROUGH RATE       PASS-THROUGH RATE            PASS-THROUGH RATE

</TABLE>

 

     The  Pass-Through Rate  for the Class  X Certificates  for any Distribution
Date will be equal to the excess of (a) the average of the Net Mortgage Rates of
the Non-Discount Mortgage Loans, weighted on  the basis of the Stated  Principal
Balances  thereof, over (b) 7.75% per annum. The Pass-Through Rate for the Class
X Certificates for the first Distribution  Date is expected to be  approximately
0.5029%  per annum. The Net Mortgage Rate for each Mortgage Loan is the Mortgage
Rate thereof (net of  the interest premium charged  by the related lenders  with
respect  to the Lender  PMI Mortgage Loans)  less the Expense  Fee Rate for such
Mortgage Loan.

     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
the  Delay Certificates will be  the calendar month preceding  the month of such
Distribution Date. With respect to each Distribution Date, the 'Interest Accrual
Period' for the  LIBOR Certificates is  the one-month period  commencing on  the
25th day of the month preceding the month in which such Distribution Date occurs
and  ending on the 24th day of the month in which such Distribution Date occurs.
The initial Interest Accrual Period for the LIBOR Certificates will commence  on
July 25, 1996.
 

     The interest entitlement described above for each Class of Certificates for
any Distribution Date 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 (i) the amount of interest that 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  with  respect  to  such
Distribution Date. 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 the  Mortgage
Loans  --  Soldiers' and  Sailors'  Civil Relief  Act'  in the  Prospectus. With
respect to any Distribution Date, a  'Net Prepayment Interest Shortfall' is  the
amount  by  which the  aggregate of  Prepayment  Interest Shortfalls  during the
portion of the Prepayment Period occurring  in the calendar month preceding  the
month  of such  Distribution Date exceeds  the aggregate amount  payable on such
Distribution Date  by  the Master  Servicer  as described  under  'Servicing  of
Mortgage  Loans -- Adjustment to Master Servicing Fee in Connection with Certain
Prepaid Mortgage  Loans.' 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 on the Stated Principal Balance of such Mortgage Loan. Each Class' pro rata
share  of such Net Interest  Shortfalls will be based  on the amount of interest
such Class otherwise would  have been entitled to  receive on such  Distribution
Date.

 
     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 in
the Certificate Account applied in the order described above under ' -- Priority
of  Distributions  Among  Certificates'  are  not  sufficient  to  make  a  full
distribution  of the interest entitlement on  the 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 Unpaid Interest 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 Unpaid Interest Amount so carried
forward 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 Notional  Amount Certificates and  the Class PO  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 a Net Mortgage
Rate  ('NMR') less  than 7.75%  (each such  Mortgage Loan,  a 'Discount Mortgage
Loan') will be equal to NMR [div] 7.75%. The Non-PO
 
                                      S-21
 
<PAGE>
<PAGE>
Percentage with respect to any Mortgage Loan  with a Net Mortgage Rate equal  to
or  greater than 7.75% (each such Mortgage Loan, a 'Non-Discount Mortgage Loan')
will be 100%. The PO Percentage with respect to any Discount Mortgage Loan  will
be  equal to (7.75%  - NMR) [div] 7.75%.  The PO Percentage  with respect to any
Non-Discount Mortgage Loan will be 0%.
 
     Non-PO Formula  Principal Amount.  On each  Distribution Date,  the  Non-PO
Formula  Principal  Amount  will  be  distributed  as  principal  of  the Senior
Certificates (other  than the  Notional  Amount Certificates  and 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 related
Prepayment Period.
 
     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-R Certificates, until the Class Certificate Balance
     thereof has been reduced to zero;

 

          (ii) concurrently,  12.83794449765%  to the  Class  A-1  Certificates,
     54.47628468897%  to the Class  A-2 Certificates and  32.68577081338% to the
     Class A-4 Certificates, until  the Class Certificate  Balance of the  Class
     A-2 Certificates has been reduced to zero;

 

          (iii)  concurrently,  12.83794449765% to  the Class  A-1 Certificates,
     54.47628468897% to the  Class A-3 Certificates  and 32.68577081338% to  the
     Class  A-4 Certificates, until the  Class Certificate Balances thereof have
     been reduced to zero; and

 

          (iv)  sequentially,  to  the  Class  A-6,  Class  A-7  and  Class  A-8
     Certificates,  in each case until the Class Certificate Balance thereof has
     been reduced to zero.

 
     Notwithstanding the foregoing, on each  Distribution Date on and after  the
Senior  Credit Support Depletion Date, the  Non-PO Formula Principal Amount will
be distributed, concurrently as principal of the Classes of Senior  Certificates
(other than the Notional Amount Certificates and the Class PO 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, if
the Senior Prepayment Percentage is less than 100%, or, if the Senior Prepayment
Percentage  equals  100%,  the  percentage  obtained  by  dividing  the   Senior
Percentage  by the  sum of  the Senior Percentage  and the  Class A-9/Class A-10
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 amount 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
amounts described in clause (f) of  the definition of 'Non-PO Formula  Principal
Amount' for such Distribution Date; provided, however, that

 
                                      S-22
 
<PAGE>
<PAGE>
if  a Bankruptcy  Loss that  is an Excess  Loss is  sustained with  respect to a
Mortgage Loan  that is  not a  Liquidated Mortgage  Loan, the  Senior  Principal
Distribution  Amount will  be reduced  on the  related Distribution  Date by the
Senior Percentage of the 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  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
A-9,  Class A-10 and 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  sum  of  the Senior
Percentage and the Class A-9/Class A-10 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 (other  than  the Class  A-9  and Class  A-10  Certificates)  which
receive  these  unscheduled  payments  of principal  (other  than  the  Class PO
Certificates) while, in the absence of Realized Losses, increasing the  interest
in  the  Pool  Principal Balance  evidenced  by  the Class  A-9  and  Class A-10
Certificates and 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 sum of the Class A-9/Class A-10 Percentage and the  Subordinated
Percentage  for such Distribution Date; for  any Distribution Date in the second
year thereafter,  the  Senior  Percentage plus  60%  of  the sum  of  the  Class
A-9/Class  A-10 Percentage and the Subordinated Percentage for such Distribution
Date; for  any  Distribution Date  in  the  third year  thereafter,  the  Senior
Percentage  plus 40% of the  sum of the Class  A-9/Class A-10 Percentage and the
Subordinated Percentage for such Distribution Date; for any Distribution Date in
the fourth year thereafter,  the Senior Percentage  plus 20% of  the sum of  the
Class  A-9/Class  A-10  Percentage  and  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 unless  one of the  following conditions  (the
'Step  Down Conditions') is satisfied: (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 on such  Distribution Date, does  not equal or  exceed
50%,  or (ii) cumulative Realized  Losses with respect to  the Mortgage Loans do
not exceed (a) with respect to the Distribution Date on the fifth anniversary of
the first Distribution Date, 30% of  the aggregate of the principal balances  of
the Subordinated Certificates as of the Cut-off 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  Combined Prepayment  Percentage as  of any  Distribution Date  will be
calculated as the difference between  100% and the Senior Prepayment  Percentage
for  such date. Except on  and after the Trigger  Date (as described below), the
Class A-9/Class A-10 Prepayment Percentage as  of any Distribution Date will  be
calculated  as the  product of  (i) a fraction,  expressed as  a percentage, the
numerator of which  is the aggregate  of the Class  Certificate Balances of  the
Class  A-9 and  Class A-10 Certificates  immediately prior  to such Distribution
Date and the  denominator of  which is the  aggregate of  the Class  Certificate
Balances  of  the Class  A-9 and  Class A-10  Certificates and  the Subordinated
Certificates immediately prior to such  Distribution Date and (ii) the  Combined
Prepayment   Percentage.  The  Subordinated  Prepayment  Percentage  as  of  any
Distribution Date  will be  calculated as  the difference  between the  Combined
Prepayment  Percentage and  the Class  A-9/Class A-10  Prepayment Percentage for
such date.
 

     If on  any Distribution  Date the  allocation to  the Class  or Classes  of
Senior  Certificates (other than the Class  A-9 or Class A-10 Certificates) then
entitled to distributions of principal of full and partial principal prepayments
and other amounts in the percentage required above would reduce the  outstanding
Class  Certificate Balance of such Class or Classes below zero, the distribution
to such Class or Classes 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(s) to zero.

 
     Class A-9/Class A-10  Principal Distribution Amount.  On each  Distribution
Date  prior to  the Senior  Credit Support  Depletion Date,  the Available Funds
remaining  after  distribution   of  interest   with  respect   to  the   Senior
Certificates,   up  to  the  amount  of   the  Class  A-9/Class  A-10  Principal
Distribution Amount for such Distribution Date, will be distributed as principal
of the Class A-9 and Class A-10 Certificates on a pro rata basis until the Class
Certificate Balances thereof have been reduced to zero.
 
     The Class A-9/Class A-10 Principal Distribution Amount for any Distribution
Date will  equal the  sum of  (i) the  Class A-9/Class  A-10 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 Class  A-9/Class A-10 Percentage of the applicable  Non-PO
Percentage  of the Stated Principal Balance of such Mortgage Loan and (y) either
(A) the Class A-9/Class A-10 Prepayment Percentage, if the Class A-9/Class  A-10
Prepayment  Percentage  is greater  than  0%, or,  if  the Class  A-9/Class A-10
Prepayment Percentage equals 0%, the  percentage obtained by dividing the  Class
A-9/Class  A-10 Percentage  by the  sum of the  Senior Percentage  and the Class
A-9/Class A-10 Percentage or (B) if an Excess Loss was sustained with respect to
such Liquidated Mortgage Loan  during such preceding  calendar month, the  Class
A-9/Class   A-10  Percentage,  of  the   applicable  Non-PO  Percentage  of  the
Liquidation Proceeds  allocable  to  principal received  with  respect  to  such
Mortgage  Loan, and (iii) the Class  A-9/Class A-10 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 Loss is sustained
with respect to  a Mortgage Loan  that is  not a Liquidated  Mortgage Loan,  the
Class  A-9/Class  A-10  Principal Distribution  Amount  will be  reduced  on the
related Distribution  Date  by  the  Class  A-9/Class  A-10  Percentage  of  the
applicable Non-PO Percentage of the principal portion of such Bankruptcy Loss.
 
     The  Class  A-9/Class  A-10 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  the Class  A-9 and  Class A-10 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.
 

     As used herein,  the Trigger  Date is the  Distribution Date  on which  the
Class  A-9 and Class A-10 Certificates are  the only remaining Classes of Senior
Certificates (other than the Class PO Certificates) outstanding.

 

     After the Trigger  Date has  occurred but prior  to the  occurrence of  the
Senior  Credit  Support  Depletion  Date, the  Class  A-9/Class  A-10 Prepayment
Percentage will equal: (i)  on any Distribution Date  prior to the  Distribution
Date  occurring in August 2001 on which  the Subordinated Percentage is equal to
or greater than twice the  initial Subordinated Percentage before giving  effect
to  distributions on such Distribution Date and  one of the Step Down Conditions
is satisfied, (A) which also occurs prior to the Distribution Date occurring  in
August  1999, an amount equal to 100% minus one-half the Subordinated Percentage
or (B) which also occurs

 
                                      S-24
 
<PAGE>
<PAGE>

on or following the Distribution Date  occurring in August 1999, the product  of
the  Class A-9/Class A-10 Percentage and  the Combined Prepayment Percentage and
(ii) on  any Distribution  Date (A)  occurring prior  to the  Distribution  Date
occurring in August 2001 on which the Subordinated Percentage is less than twice
the  initial Subordinated  Percentage before  giving effect  to distributions on
such Distribution Date, (B) occurring on or  after August 2001 and prior to  the
Distribution  Date occurring  in August  2005 on  which (1)  the aggregate Class
Certificate Balance of  the Subordinated Certificates  is less than  50% of  the
aggregate Class Certificate Balance of the Class A-9 and Class A-10 Certificates
or  (2) the  outstanding principal balance  of all Mortgage  Loans delinquent 60
days or more is greater than one-half of the aggregate Class Certificate Balance
of the Subordinated Certificates immediately prior to such Distribution Date  or
(C)  occurring on  or after  the Distribution Date  occurring in  August 2005 on
which  the  Subordinated  Percentage  is  less  than  the  initial   Subordinate
Percentage, 100%.

 

     If  on any Distribution  Date following the Trigger  Date the allocation to
the Class A-9 and Class A-10 Certificates would reduce the aggregate outstanding
Class Certificate Balance  of the Class  A-9 and Class  A-10 Certificates  below
zero, the distribution to the Class A-9 and Class A-10 Certificates of the Class
A-9/Class  A-10 Prepayment Percentage of such amounts for such Distribution Date
will be limited  to the  percentage necessary  to reduce  the Class  Certificate
Balance of the Class A-9 and Class A-10 Certificates 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  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. Distributions of principal of the
Subordinated   Certificates  will  be  made   sequentially  to  the  Classes  of
Subordinated Certificates in  the order of  their numerical Class  designations,
beginning   with  the  Class  B-1   Certificates,  until  the  respective  Class
Certificate Balances thereof are reduced to zero.
 
     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  of partial  principal prepayments and  principal prepayments  in
full  otherwise distributable to the Restricted  Classes will be allocated among
the remaining Classes of Subordinated  Certificates, pro rata, based upon  their
respective  Class Certificate Balances, and  distributed in the sequential 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 such  amounts
pursuant  to  clause (ii)  of the  definition  of Senior  Principal Distribution
Amount and pursuant  to clause (ii)  of the definition  of Class A-9/Class  A-10
Principal  Distribution  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  payments  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  and Class  PO Deferred  Amounts on  the Class  PO Certificates and
interest and principal on the Subordinated Certificates, 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 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,  the  Senior  Principal  Distribution  Amount  and  the  Class
A-9/Class A-10 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 A-9,  Class A-10 and Class PO
Certificates) will be in an amount equal  to the product of (i) Available  Funds
remaining  after 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 Senior Principal Distribution Amount,
the  PO  Formula  Principal  Amount  and  the  Class  A-9/Class  A-10  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 Class A-9 and Class A-10 Certificates  will be in an amount equal to the
product of (i) Available Funds remaining  after distribution of interest on  the
Senior  Certificates and (ii)  a fraction, the  numerator of which  is the Class
A-9/Class A-10 Principal Distribution Amount and the denominator of which is the
sum of the PO Formula Principal Amount, the Senior Principal Distribution Amount
and the Class A-9/Class A-10 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 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  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  related
Prepayment  Period;  provided, however,  that if  a Bankruptcy  Loss that  is an
Excess Loss is sustained with respect to a Discount Mortgage Loan that is not  a
Liquidated Mortgage Loan, the PO Formula Principal Amount will be reduced on the
related  Distribution  Date by  the applicable  PO  Percentage of  the principal
portion of such Bankruptcy Loss.
 
ALLOCATION OF LOSSES
 
     On each Distribution  Date, the  applicable PO Percentage  of any  Realized
Loss,  including any Excess Loss, on a  Discount Mortgage Loan 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-26
 
<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, except  that the  pro rata  portion of  any such Realized
Loss, including an Excess  Loss, otherwise allocable to  the Class A-6 or  Class
A-8  Certificates, will be  allocated to the Class  A-10 Certificates, until the
Class Certificate Balance thereof is reduced to zero.

 
     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. Realized Losses allocated  to the Class  A-4 Certificates will  reduce
the Notional Amount of the Class A-5 Certificates.
 
     Because principal distributions are paid to certain Classes of Certificates
(other  than the  Class PO Certificates)  before other  Classes of Certificates,
holders of such 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  losses sustained on  a Liquidated  Mortgage
Loan by reason of a default arising from fraud, dishonesty or misrepresentation.
See 'Credit Enhancement -- Subordination of Certain Classes' herein.

 
     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:

(ii)  the Mortgage  Loans prepay at  the specified constant  percentages of SPA,
(iii) no defaults in the payment by  Mortgagors of principal of and interest  on
the  Mortgage Loans  are experienced,  (iv) scheduled  payments on  the Mortgage
Loans are received on  the first day  of each month  commencing in the  calendar
month  following the  Closing Date  and are computed  prior to  giving effect to
prepayments received on  the last day  of the prior  month, (v) prepayments  are
allocated  as described  herein without  giving effect  to loss  and delinquency
tests, (vi)  there are  no  Net Interest  Shortfalls and  prepayments  represent
prepayments  in full of 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 such
that each Mortgage Loan will amortize in amounts sufficient to repay the current
balance of such  Mortgage Loan  by its  respective 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,'  (ix)
interest  accrues  on  each  interest  bearing  Class  of  Certificates  at  the
applicable interest  rate set  forth or  described on  the cover  hereof and  as
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 the date set forth under 'Summary of Terms -- Closing Date,' (xii) the Seller
is  not required to repurchase  or substitute for any  Mortgage Loan, (xiii) the
Master Servicer does not  exercise the option to  repurchase the Mortgage  Loans
described   herein  under  '  --  Optional  Purchase  of  Defaulted  Loans'  and
' --  Optional  Termination'  and  (xiv) no  Class  of  Certificates  becomes  a
Restricted Class. While it is assumed that each of the Mortgage Loans prepays at
the  specified constant percentages of  SPA, this is not  likely to be the case.
Moreover, discrepancies  may exist  between the  characteristics of  the  actual
Mortgage Loans which will be delivered to the Trustee and characteristics of the
Mortgage Loans used in preparing the tables herein.

 
     Prepayments   of  mortgage  loans  commonly  are  measured  relative  to  a
prepayment standard or model.  The model used in  this Prospectus Supplement  is
the  Standard Prepayment Assumption ('SPA'), which 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 a 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, 225% SPA assumes prepayment rates will be 0.45% per annum in month one,
0.90% per annum in month two, and  increasing by 0.45% in each succeeding  month
until  reaching a rate of 13.5% per annum  in month 30 and remaining constant at
13.5% 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.
 
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 (and not reimbursed) 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. In the event the Master
Servicer exercises such option, the  purchase price distributed with respect  to
each Certificate will be 100% of its then outstanding principal balance plus any
Class  PO Deferred Amounts in the case of  the Class PO Certificates and, in the
case of an interest bearing Certificate, any unpaid accrued interest thereon  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
 
                                      S-28

<PAGE>
and  such  appraised value  is less  than  the Stated  Principal Balance  of the
related Mortgage Loans).  Distributions on  the Certificates in  respect of  any
such optional termination will first be paid to the Senior Certificates and then
to  the Subordinated Certificates.  The proceeds from  any such distribution may
not be  sufficient  to  distribute  the  full amount  to  which  each  Class  of
Certificates is entitled if the purchase price is based in part on the appraised
value  of any  REO Property  and such  appraised value  is less  than the Stated
Principal Balance of the related Mortgage Loan.
 
THE TRUSTEE
 
     The Bank of New York will be the Trustee under the Agreement. The Depositor
and the Master Servicer may maintain other banking relationships in the ordinary
course of  business with  The Bank  of  New York.  Offered Certificates  may  be
surrendered  at the Corporate Trust Office of the Trustee located at 101 Barclay
Street, 12E, New York, New York 10286, Attention: Corporate Trust Administration
or at such other addresses as the Trustee may designate from time to time.
 
RESTRICTIONS ON TRANSFER OF THE CLASS A-R CERTIFICATES
 
     The Class A-R Certificates will be subject to the restrictions on  transfer
described    in   the    Prospectus   under   '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 yield to the holders of the Delay Certificates will be lower
than the yield 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  will adversely affect  the yields  on the 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 (other than  the Notional Amount Certificates) on  a
pro  rata basis, except that the pro  rata portion of Excess Losses allocated to
the Class A-6  or Class A-8  Certificates will  be allocated to  the Class  A-10
Certificates,  until the Class  Certificate Balance thereof  is reduced to zero.
Moreover,  since  the  Subordinated  Principal  Distribution  Amount  for   each
Distribution  Date will be  reduced by the  amount of any  distributions on such
Distribution  Date  in  respect  of  Class  PO  Deferred  Amounts,  the   amount
distributable  as  principal on  each such  Distribution Date  to each  Class of
Subordinated Certificates 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.

PREPAYMENT CONSIDERATIONS AND RISKS
 
     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. 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 of  the Mortgage Loans  will depend on future
events and a variety of  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 Interest Only Certificates
and any  other  Offered  Certificate  purchased at  a  premium,  a  faster  than
anticipated  rate of principal payments could result  in an actual yield to such
investor that is  lower than the  anticipated yield. Investors  in the  Interest
Only  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.
 
     The rate of principal payments (including prepayments) on pools of mortgage
loans  may vary  signifiantly 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  addition,  Countrywide's
Streamlined Documentation  Program may  affect the  rate of  prepayments on  the
Mortgage   Loans.  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 A-9, Class A-10  and Class PO Certificates)
then entitled to receive principal prepayment distributions. This may result  in
all  (or  a disproportionate  percentage)  of such  principal  prepayments being
distributed to holders of such Classes of Senior Certificates and none (or  less
than  their pro rata  share) of such principal  prepayments being distributed to
holders of  the Class  A-9  and Class  A-10  Certificates and  the  Subordinated
Certificates  during the periods of time  described in the definition of 'Senior
Prepayment Percentage.'

 

     Except upon the  occurrence of the  Trigger Date, the  Class A-9 and  Class
A-10  Certificates  will  be entitled  to  receive distributions  in  respect of
principal prepayments  only if,  as  and to  the  extent that  the  Subordinated
Certificates  are  entitled to  receive such  distributions. Thus,  the weighted
average lives of the Class A-9 and  Class A-10 Certificates will be longer  than
would  be the case if such Certificates  were to receive such distributions with
the other Classes of Senior Certificates.  In addition, on and after the  Senior
Credit  Support  Depletion  Date,  Realized  Losses,  including  Excess  Losses,
otherwise allocable to the Class A-6  or Class A-8 Certificates will instead  be
allocated  to the Class A-10 Certificates. Due to the relatively longer weighted
average life of  the Class  A-10 Certificates, such  Class will  have a  greater
possibility of being allocated Realized Losses.

     The  timing of changes in the rate of prepayments on the Mortgage Loans may
significantly affect an investor's actual yield to maturity, even if the average
rate of  principal payments  is consistent  with an  investor's expectation.  In
general,  the  earlier a  prepayment  of principal  on  the Mortgage  Loans, the
greater the  effect  on  an investor's  yield  to  maturity. The  effect  on  an
investor's  yield as a result  of principal payments occurring  at a rate higher
(or lower)  than  the  rate  anticipated  by  the  investor  during  the  period
immediately following the issuance of the Offered Certificates may not be offset
by a subsequent like decrease (or increase) in the rate of principal payments.
 
     The  tables below  indicate the sensitivity  of the  pre-tax corporate bond
equivalent yields  to maturity  of certain  Classes of  Certificates to  various
constant  percentages of SPA. The yields set forth in the tables were calculated
by determining the  monthly discount  rates that,  when applied  to the  assumed
streams  of cash  flows to  be paid on  the applicable  Classes of Certificates,
would cause the discounted present value  of such assumed streams of cash  flows
to  equal the assumed  aggregate 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  Certificate when such  reinvestment rates  are
considered.
 
SENSITIVITY OF THE CLASS X CERTIFICATES
 

     AS  INDICATED IN  THE TABLE BELOW,  THE YIELD  TO INVESTORS IN  THE CLASS X
CERTIFICATES WILL  BE SENSITIVE  TO THE  RATE OF  PRINCIPAL PAYMENTS  (INCLUDING
PREPAYMENTS)  OF THE NON-DISCOUNT  MORTGAGE LOANS (PARTICULARLY  THOSE WITH HIGH
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  X
CERTIFICATES  WOULD  BE  APPROXIMATELY 0%  IF  PREPAYMENTS  WERE TO  OCCUR  AT A
CONSTANT RATE OF APPROXIMATELY  660% SPA. IF THE  ACTUAL PREPAYMENT RATE OF  THE
NON-DISCOUNT  MORTGAGE LOANS WERE TO EXCEED THE FOREGOING LEVEL FOR AS LITTLE AS
ONE MONTH WHILE EQUALING SUCH LEVEL  FOR THE REMAINING MONTHS, THE INVESTORS  IN
THE CLASS X 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 Net  Mortgage Rates of the Non-Discount Mortgage
Loans. The Non-Discount Mortgage Loans will have higher Net Mortgage Rates  (and
higher 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 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 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  purchase
price of the Class X Certificates (expressed as a percentage of initial Notional
Amount) is as follows:

     It is unlikely that the Non-Discount  Mortgage Loans will have the  precise
characteristics  described herein or  that the Non-Discount  Mortgage Loans will
all prepay at  the same  rate until  maturity or  that all  of the  Non-Discount
Mortgage  Loans will  prepay at  the same  rate or  time. As  a result  of these
factors, the pre-tax  yields on the  Class X Certificates  are likely to  differ
from those shown in the table above, even if all of the Mortgage Loans prepay at
the  indicated percentages of  SPA. No representation  is made as  to the actual
rate of principal  payments on the  Mortgage Loans  for any period  or over  the
lives  of  the  Class  X  Certificates  or  as  to  the  yield  on  the  Class X

prepayment  assumptions to be used  in deciding whether to  purchase the Class X

SENSITIVITY OF THE INVERSE FLOATING RATE CERTIFICATES
 
     THE YIELDS  TO  INVESTORS  IN  THE CLASS  A-5  CERTIFICATES  WILL  BE  VERY
SENSITIVE  TO THE LEVEL OF  LIBOR AND THE RATE  AND TIMING OF PRINCIPAL PAYMENTS
(INCLUDING PREPAYMENTS) OF THE MORTGAGE LOANS, WHICH GENERALLY CAN BE PREPAID AT
ANY TIME. AS INDICATED  IN THE TABLE  BELOW, AN INCREASING  LEVEL OF LIBOR  WILL
HAVE  A NEGATIVE EFFECT ON  THE YIELD TO INVESTORS  IN THE INVERSE FLOATING RATE
CERTIFICATES.
 
     Changes in the level of LIBOR may not correlate with changes in  prevailing
mortgage  interest rates. It is possible that lower prevailing mortgage interest
rates, which might  be expected  to result  in faster  prepayments, could  occur
concurrently with an increased level of LIBOR.
 
     The  information set forth in the following table was prepared on the basis
of the Structuring Assumptions  and the assumptions that  (i) the interest  rate
applicable  to the Inverse Floating Rate  Certificates for each Interest Accrual
Period subsequent to their initial Interest Accrual Period will be based on  the
indicated  level of LIBOR and  (ii) the aggregate purchase  price of the Inverse
Floating Rate Certificates  (expressed as  percentages of  its initial  Notional
Amount) is as follows:

* The pre-tax yield to maturity will be less than (99.9)%.
 
     It is  highly  unlikely  that all  of  the  Mortgage Loans  will  have  the
characteristics  assumed or that the Mortgage Loans will prepay at the same rate
until maturity or that all of the Mortgage Loans will prepay at the same rate or
time. In addition, there can be no  assurance that LIBOR will correspond to  the
levels  shown herein  and it  is highly  unlikely that  the level  of LIBOR will
remain constant. As a result of these factors, the pre-tax yield on the  Inverse
Floating  Rate Certificates is  likely to differ  from those shown  in the table
above, even if all of the Mortgage Loans prepay at the indicated percentages  of
SPA  and LIBOR is  at the indicated level.  No representation is  made as to the
actual rate of principal payments  on the Mortgage Loans  or the level of  LIBOR
for any period or over the lives of the Inverse Floating Rate Certificates or as
to  the yield  on the  Inverse Floating  Rate Certificates.  Investors must make
their own decisions as to the appropriate combinations of prepayment assumptions
and assumptions regarding the level of LIBOR  to be used in deciding whether  to
purchase the Inverse Floating Rate Certificates.
 
SENSITIVITY OF THE PRINCIPAL ONLY CERTIFICATES
 
     THE  CLASS PO CERTIFICATES  WILL BE 'PRINCIPAL  ONLY' CERTIFICATES AND WILL
NOT BEAR INTEREST.  AS INDICATED IN  THE TABLE BELOW,  A LOWER THAN  ANTICIPATED
RATE  OF  PRINCIPAL PAYMENTS  (INCLUDING PREPAYMENTS)  ON 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  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 change 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.

     It  is  unlikely that  the Discount  Mortgage Loans  will have  the precise
characteristics described herein or  that the Discount  Mortgage Loans will  all
prepay  at the same  rate until maturity  or that all  of such Discount 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  Mortgage Loans  prepay at  the
indicated percentages of SPA. No representation is made as to the actual rate of
principal  payments on the Mortgage Loans for any period or over the life of the
Principal  Only  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.
 
WEIGHTED AVERAGE LIVES OF THE OFFERED CERTIFICATES
 
     The  weighted average life  of an Offered Certificate  is determined by (a)
multiplying the amount of  the net 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 net  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 percentages of  SPA, see  the
Decrement Tables below.

DECREMENT TABLES
 
     The  following  tables  indicate  the  percentages  of  the  initial  Class
Certificate Balances or Notional Amount, as the  case may be, of the Classes  of
Offered  Certificates  (other  than  the Class  X  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 tables  have
been prepared on the basis of the Structuring Assumptions. It is not likely that
(i) the Mortgage Loans will have the precise characteristics described herein or
(ii)  all of  the Mortgage Loans  will prepay  at a constant  percentage of SPA.
Moreover, the diverse remaining  terms to maturity of  the Mortgage Loans  could
produce  slower or faster principal distributions  than indicated in the tables,
which have been prepared using the  specified constant percentages of SPA,  even
if  the 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.

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 following the month of the  latest scheduled maturity date for any  of
the  Mortgage Loans. Since the  rate of distributions in  reduction of the Class
Certificate Balance or  Notional Amount  of each Class  of Offered  Certificates
will  depend  on the  rate of  payment (including  prepayments) of  the Mortgage
Loans, 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  'Yield, Prepayment  and
Maturity   Considerations   --   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  life  of,  and  the  yield  to  maturity  on,  the
Subordinated  Certificates,  in  increasing  order  of  their  numerical   Class
designation,  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  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  yield  to
maturity  of  the  Subordinated  Certificates  will  also  be  affected  by  the
disproportionate allocation of principal prepayments to the Senior Certificates,
Net  Interest  Shortfalls,  other  cash   shortfalls  in  Available  Funds   and
distribution  of funds  to Class  PO Certificateholders  otherwise available for
distribution on the Subordinated Certificates to the extent of reimbursement for
Class PO Deferred Amounts. See 'Description of the Certificates -- Allocation of
Losses' herein.
 
     If on any Distribution Date,  the Applicable Credit Support Percentage  for
any  Class of  Subordinated Certificates  is less  than its  Original Applicable
Credit Support  Percentage,  all  partial principal  prepayments  and  principal
prepayments  in full available for distribution on the Subordinated Certificates
will be allocated  solely to such  Class and all  other Classes of  Subordinated
Certificates  with lower numerical Class  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   Class   or  Classes   of   Subordinated   Certificates   with
 
                                      S-37
 
<PAGE>
<PAGE>
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 subordination of  the Classes of Subordinated Certificates
with higher numerical  Class designations  to those with  lower numerical  Class
designations is intended to increase the likelihood of receipt, respectively, by
the  Senior Certificateholders and the holders of Subordinated Certificates with
lower numerical  Class designations  of the  maximum amount  to which  they  are
entitled on any Distribution Date and to provide such holders protection against
Realized  Losses,  other  than  Excess  Losses.  In  addition,  the Subordinated
Certificates will  provide limited  protection  against Special  Hazard  Losses,
Bankruptcy  Losses  and Fraud  Losses  up to  the  Special Hazard  Loss Coverage
Amount,  Bankruptcy  Loss  Coverage  Amount  and  Fraud  Loss  Coverage  Amount,
respectively,  as described below. 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  limited  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 $2,232,193 (the
'Special Hazard Loss  Coverage Amount'),  (ii) Bankruptcy Losses  in an  initial
amount  expected  to  be  up to  approximately  $100,000  (the  'Bankruptcy Loss
Coverage Amount') and (iii) Fraud Losses in an initial amount expected to be  up
to approximately $3,253,766 (the 'Fraud Loss Coverage Amount').

 
     The Special Hazard Loss Coverage Amount will be reduced, from time to time,
to be an amount equal on any Distribution Date to the lesser of (a) the greatest
of (i) 1% of the aggregate of the principal balances of the Mortgage Loans, (ii)
twice the principal balance of the largest Mortgage Loan and (iii) the aggregate
principal balances of the Mortgage Loans secured by Mortgaged Properties located
in  the  single California  postal zip  code area  having the  highest aggregate
principal balance of  any such zip  code area  and (b) the  Special Hazard  Loss
Coverage  Amount  as of  the Closing  Date less  the amount,  if any,  of losses
attributable to Special Hazard Mortgage  Loans incurred since the Closing  Date.
All  principal balances for the purpose of this definition will be calculated as
of the first  day of  the month preceding  such Distribution  Date after  giving
effect to scheduled installments of principal and interest on the Mortgage Loans
then due, whether or not paid.
 
     The  Fraud Loss Coverage Amount will be  reduced, from time to time, by the
amount of  Fraud Losses  allocated to  the Certificates.  In addition,  on  each
anniversary  of the Cut-off Date, the Fraud Loss Coverage Amount will be reduced
as follows: (a)  on the  first, second, third  and fourth  anniversaries of  the
Cut-off  Date, to an  amount equal to the  lesser of (i) 1%  of the then current
Pool Principal Balance and (ii) the excess of the Fraud Loss Coverage Amount  as
of  the preceding anniversary of the Cut-off  Date over the cumulative amount of
Fraud Losses allocated to the Certificates since such preceding anniversary  and
(b) on the fifth anniversary of the Cut-off Date, to zero.
 
     The  Bankruptcy Loss Coverage Amount will be reduced, from time to time, by
the amount of Bankruptcy Losses allocated to the Certificates.
 
     The amount  of  coverage  provided by  the  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 guaranty  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
 
                                      S-38
 
<PAGE>
<PAGE>
the  Master Servicer is pursuing  any other remedies that  may be available with
respect to  the related  Mortgage Loan  and (i)  such Mortgage  Loan is  not  in
default  with  respect  to  payment due  thereunder  or  (ii)  scheduled monthly
payments of principal  and interest are  being advanced by  the Master  Servicer
without giving effect to any Debt Service Reduction or Deficient Valuation.
 
                                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, the Trust Fund will include two segregated
asset pools, with respect  to which elections  will be made to  treat each as  a
separate   REMIC.  One  REMIC  (the   'Subsidiary  REMIC')  will  issue  several
uncertificated subclasses  of  nonvoting interests  ('Subsidiary  REMIC  Regular
Interests'), which will be designated as the regular interests in the Subsidiary
REMIC. The assets of the Subsidiary REMIC will consist of the Mortgage Loans and
all  other property in the Trust Fund except  for the property in the Trust Fund
allocated to the second REMIC (the 'Master REMIC'). The Master REMIC will  issue
the  Regular Certificates, which will be  designated as the regular interests in
the Master  REMIC. The  Class  A-R Certificates  will represent  the  beneficial
ownership  of the  residual interest  in the  Subsidiary REMIC  and the residual
interest in the Master REMIC. The assets of the Master REMIC will consist of the
Subsidiary REMIC Regular  Interests. Aggregate distributions  on the  Subsidiary
REMIC  Regular Interests will  equal the aggregate  distributions on the Regular
Certificates  issued   by   the   Master  REMIC.   See   'Description   of   the
Certificates -- Separate REMIC Structure' herein.
 
     The  Regular  Certificates generally  will be  treated as  debt instruments
issued by  the REMIC  for federal  income tax  purposes. Income  on the  Regular
Certificates must be reported under an accrual method of accounting.
 

     The  Principal Only  Certificates will  be treated  for federal  income tax
purposes as having been issued with an amount of Original Issue Discount ('OID')
equal to the difference between their  principal balance and their issue  price.
Although the tax treatment is not entirely certain, Notional Amount Certificates
will  be treated as having been issued  with OID for federal income tax purposes
equal to the excess  of all expected payments  of interest on such  Certificates
over  their  issue  price.  Although  unclear, a  holder  of  a  Notional Amount
Certificate may be entitled to  deduct a loss to  the extent that its  remaining
basis   exceeds  the   maximum  amount   of  future   payments  to   which  such
Certificateholder would be entitled if there were no further prepayments of  the
Mortgage  Loans.  The remaining  Classes of  Regular Certificates,  depending on
their respective issue  prices (as  described in the  Prospectus under  '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 225% SPA (the
'Prepayment Assumption'). No representation is  made as to whether the  Mortgage
Loans  will  prepay  at  the  foregoing rate  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   proposed
regulations (the 'Proposed Contingent Regulations') governing the calculation of
OID  on instruments having contingent interest payments. The Proposed Contingent
Regulations, although not effective until 60 days after finalized, represent the
only guidance regarding the views of the IRS with respect to contingent interest
instruments and specifically  do not apply  for purposes of  calculating OID  on
debt  instruments  subject  to  Code Section  1272(a)(6),  such  as  the Regular
Certificates. Additionally,  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). Until the Treasury
issues guidance to the contrary, 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
 
                                      S-39
 
<PAGE>
<PAGE>
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
each 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 --  Residual  Certificates --  Mark  to Market  Rules  --  Residual
Certificates  -- Excess Inclusions and  -- 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 '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 Salomon Brothers  Inc (Prohibited Transaction  Exemption 89-89, as
amended, Exemption Application No. D-6446,  54 Fed. Reg. 42,589 (1989)  (Salomon
Brothers)  (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 A-10, 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 A-10
CLASS B-1, CLASS B-2 AND CLASS B-3 CERTIFICATES BELOW.
 
     BECAUSE THE CHARACTERISTICS OF THE CLASS A-10, CLASS B-1, CLASS B-2,  CLASS
B-3  AND CLASS A-R 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-10, CLASS B-1, CLASS B-2, CLASS B-3 AND CLASS A-R 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-10, CLASS  B-1,
CLASS  B-2, CLASS B-3 AND  CLASS A-R 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  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 A-10,  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
described in the Prospectus and the Exemption, and the potential consequences in
their specific  circumstances, prior  to  making an  investment  in any  of  the
Offered  Certificates. Moreover,  each Plan  fiduciary should  determine whether
under the general fiduciary standards of investment
 
                                      S-41
 
<PAGE>
<PAGE>
prudence and diversification, an investment  in any of 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 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
sufficient level of liquidity of investment.
 

     The  Depositor has  agreed to  indemnify the  Underwriter against,  or make
contributions to the Underwriter with respect to, certain liabilities, including
liabilities under the Securities Act of 1933, as amended.

 
     The Class X and Class PO Certificates may be offered by the Depositor  from
time  to time directly  or through underwriters  or agents (either  of which may
include Countrywide Securities  Corporation, an affiliate  of the Depositor  and
the  Master Servicer) in  one or more negotiated  transactions, or otherwise, at
varying prices to be  determined at the  time of sale, in  one or more  separate
transactions  at prices to be  negotiated at the time  of each sale. Proceeds to
the Depositor from any sale of the  Class X or Class PO Certificates will  equal
the purchase price paid by the purchaser thereof, net of any expenses payable by
the Depositor and any compensation payable to any such underwriter or agent. Any
underwriters  or agents that participate  in the distribution of  the Class X or
Class PO Certificates may be deemed  to be 'underwriters' within the meaning  of
the  Securities Act of 1933  and any profit on the  sale of such Certificates by
them and any discounts, commissions, concessions or other compensation  received
by  any such underwriter or agent may be deemed to be underwriting discounts and
commissions under such Act.
 
                                 LEGAL MATTERS
 

     The validity  of the  Certificates, including  certain federal  income  tax
consequences  with respect  thereto, will  be passed  upon for  the Depositor by
Brown & Wood LLP, New York, New York.  Stroock & Stroock & Lavan, New York,  New
York, will pass upon certain legal matters on behalf of the Underwriter.

 
                                    RATINGS
 
     It  is a condition to the issuance  of the Senior Certificates that they be
rated AAA by  Fitch Investors Service,  L.P. (Fitch) and,  other than the  Class
A-5,  Class PO and Class X Certificates,  AAA by Standard & Poor's Ratings Group
('S&P' and, together with Fitch, the 'Rating Agencies'). The Class A-5, Class PO
and Class X Certificates  will 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 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 payments  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
 
                                      S-42
 
<PAGE>
<PAGE>
prepayments on the  related mortgage loans.  The 'r' symbol  is appended to  the
rating  by  S&P  of the  Class  PO and  Class  X Certificates  because  they are
principal only  or  interest only  mortgage  securities that  S&P  believes  may
experience  high  volatility  or high  variability  in expected  returns  due to
non-credit risks created by  the terms of such  Certificates. The absence of  an
'r'  symbol in the ratings of the other Offered Certificates should not be taken
as an indication 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  security  ratings  assigned  to  the  Offered  Certificates  should be
evaluated independently from  similar ratings  on other types  of securities.  A
security  rating is not a recommendation to buy, sell or hold securities and may
be subject to revision or withdrawal at any time by the 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

       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

                                                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.

                                                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.
                                            (d) The  Mortgage Loans generally may be  prepaid at any time without
                                                payment of any  prepayment fee.  If so specified  in the  related

                                                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

                                            The rights  of the  holders  of the  Subordinated Certificates  of  a
                                            Series    (the   'Subordinated    Certificateholders')   to   receive
                                            distributions with respect to  the assets in  the related Trust  Fund
                                            will  be subordinated  to such  rights of  the holders  of the Senior

                                            the  extent  described  in the  related  Prospectus  Supplement. This
                                            subordination is  intended  to  enhance  the  likelihood  of  regular
                                            receipt  by  Senior Certificateholders  of the  full amount  of their
                                            scheduled monthly payments of principal and interest. The  protection
                                            afforded to the Senior Certificateholders of a Series by means of the
                                            subordination  feature will  be accomplished by  (i) the preferential
                                            right of such  holders to  receive, prior to  any distribution  being
                                            made in respect of the related Subordinated Certificates, the amounts
                                            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
                                            Prospectus Supplement, by the right of such holders to receive future
                                            distributions on  the assets  in the  related Trust  Fund that  would
                                            otherwise  have been payable  to the 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
                                            forth  information  concerning,  among other  things,  the  amount of
                                            subordination of a class or classes of Subordinated Certificates in a
                                            Series,  the  circumstances  in  which  such  subordination  will  be
                                            applicable   and  the  manner,  if  any,   in  which  the  amount  of
                                            subordination will decrease over time.
B. Reserve Fund...........................  One or more reserve funds (the 'Reserve Fund') may be established and
                                            maintained for each  Series. The related  Prospectus Supplement  will

                                            of  counsel to  the effect  that such transfer  will not  result in a

                                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
 
- ------------------------------
* 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.
 
                                       11

     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.
 
          (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
 
                                       12
 
<PAGE>
<PAGE>
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 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
 
                                       13
 
<PAGE>
<PAGE>
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, 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).
 
                                       14
 
<PAGE>
<PAGE>
     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.
 
     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,
 
                                       15

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 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
 
                                       16
 
<PAGE>
<PAGE>
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  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  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'.
 
                                       19
 
<PAGE>
<PAGE>
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.
 
     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 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 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 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
 
                                       23
 
<PAGE>
<PAGE>
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  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.
 
                                       24
 
<PAGE>
<PAGE>
     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 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
 
                                       25
 
<PAGE>
<PAGE>
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
     identifying  the aggregate amount  of any Principal  Prepayments and, if so
     specified  in  the  related  Prospectus  Supplement,  prepayment  penalties
     included therein;
 
          (ii) the amount of such distribution allocable to interest;
 
          (iii) the amount of any Advance;
 
          (iv)  the aggregate amount (a) otherwise allocable to the Subordinated
     Certificateholders on such  Distribution Date  and (b)  withdrawn from  the
     Reserve  Fund, if any, that  is included in the  amounts distributed to the
     Certificateholders;
 
          (v) the Class Certificate Balance or notional amount of each class  of
     the  related Series after giving effect to the distribution of principal on
     such Distribution Date;
 
          (vi) the  percentage  of principal  payments  on the  Mortgage  Assets
     (excluding  prepayments), if any, which each such class will be entitled to
     receive on the following Distribution Date;
 
          (vii) the  percentage of  Principal Prepayments  with respect  to  the
     Mortgage  Assets, if any, which each such class will be entitled to receive
     on the following Distribution Date;
 
          (viii) the related  amount of the  servicing compensation retained  or
     withdrawn  from the  Certificate Account  by the  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,
     (2) 31 to 60 days,  (3) 61 to 90  days and (4) 91 or  more days and (B)  in
     foreclosure  and delinquent (1) 1 to 30 days,  (2) 31 to 60 days, (3) 61 to
     90 days and (4) 91 or  more days, as of the  close of business on the  last
     day of the calendar month preceding such Distribution Date;
 
          (x)  the book value of any real estate acquired through foreclosure or
     grant of a deed in lieu of foreclosure;
 
          (xi) the Pass-Through  Rate, if  adjusted from  the date  of the  last
     statement,  of  any  such  class  expected to  be  applicable  to  the next
     distribution to such class;
 
          (xii) if applicable, the amount remaining  in the Reserve Fund at  the
     close of business on the Distribution Date;
 
          (xiii)  the Pass-Through Rate  as of the day  prior to the immediately
     preceding Distribution Date; and
 
          (xiv) any amounts remaining under letters of credit, pool policies  or
     other forms of credit 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
 
                                       26
 
<PAGE>
<PAGE>
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.

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.
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.

INDICES APPLICABLE TO FLOATING RATE AND INVERSE FLOATING RATE CLASSES
 
LIBOR
 
     Unless otherwise specified  in the  related Prospectus  Supplement, on  the
LIBOR  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  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
 
                                       28

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
 
                                       29
 
<PAGE>
<PAGE>
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.

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  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).

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.

     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
 
                                       32
 
<PAGE>
<PAGE>
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
 
                                       33
 
<PAGE>
<PAGE>
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 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.
 
                                       34
 
<PAGE>
<PAGE>
     Unless  otherwise  specified  in  the  related  Prospectus  Supplement,  no
Mortgage  Pool Insurance Policy will insure (and many Primary Mortgage Insurance
Policies do not insure)  against loss sustained by  reason of a default  arising
from,  among  other  things,  (i)  fraud or  negligence  in  the  origination or
servicing of a Mortgage Loan, including misrepresentation by the Mortgagor,  the
originator  or persons involved  in the origination thereof,  or (ii) failure to
construct a Mortgaged Property  in accordance with  plans and specifications.  A
failure  of coverage attributable to one of the foregoing events might result in
a breach of the  related Seller's representations described  above and, in  such
event, might give rise to an obligation on the part of such Seller to 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
 
                                       35
 
<PAGE>
<PAGE>
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.
 
                                       36
 
<PAGE>
<PAGE>
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  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
 
                                       37
 
<PAGE>
<PAGE>
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
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.
 
                                       39
 
<PAGE>
<PAGE>
     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;
 
                                       40
 
<PAGE>
<PAGE>
          (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 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.
 
                                       41

<PAGE>
     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
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
 
                                       42
 
<PAGE>
<PAGE>
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  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
 
                                       43

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 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.
 
                                       44

     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 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
 
                                       45
 
<PAGE>
<PAGE>
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
 
                                       46
 
<PAGE>
<PAGE>
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  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
 
                                       47
 
<PAGE>
<PAGE>
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  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
 
                                       48
 
<PAGE>
<PAGE>
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 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
 
                                       49
 
<PAGE>
<PAGE>
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 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
 
                                       50
 
<PAGE>
<PAGE>
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 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
 
                                       51
 
<PAGE>
<PAGE>
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
 
                                       52
 
<PAGE>
<PAGE>
the  proprietary lease or occupancy agreement  will usually constitute a default
under the security agreement between the lender and the tenant-stockholder.
 
     The recognition agreement generally  provides that, in  the event that  the
tenant-stockholder  has  defaulted  under  the  proprietary  lease  or occupancy
agreement, the  Cooperative will  take  no action  to  terminate such  lease  or
agreement  until the lender  has been provided  with an opportunity  to cure the
default. The recognition  agreement typically provides  that if the  proprietary
lease  or occupancy agreement is terminated,  the Cooperative will recognize the
lender's lien  against proceeds  from  the sale  of the  Cooperative  apartment,
subject,  however, to the Cooperative's right to sums due under such proprietary
lease or occupancy agreement.  The total amount owed  to the Cooperative by  the
tenant-stockholder,  which  the lender  generally cannot  restrict and  does not
monitor, could  reduce  the  value  of  the  collateral  below  the  outstanding
principal  balance  of  the Cooperative  Loan  and accrued  and  unpaid interest
thereon.
 
     Recognition agreements also provide that in the event of a foreclosure on a
Cooperative Loan,  the  lender  must  obtain the  approval  or  consent  of  the
Cooperative  as  required  by  the  proprietary  lease  before  transferring the
Cooperative shares or assigning the proprietary lease. Generally, the lender  is
not limited in any rights it may have to dispossess the tenant-stockholders.
 
     In  some states, foreclosure on the Cooperative shares is accomplished by a
sale in accordance with  the provisions of Article  9 of the Uniform  Commercial
Code  (the 'UCC') and the security agreement relating to those shares. Article 9
of the UCC  requires that  a sale be  conducted in  a 'commercially  reasonable'
manner.  Whether  a  foreclosure  sale has  been  conducted  in  a 'commercially
reasonable' manner  will  depend on  the  facts  in each  case.  In  determining
commercial  reasonableness, a court will look to the notice given the debtor and
the method, manner, time, place and terms of the foreclosure. Generally, a  sale
conducted  according to the  usual practice of  banks selling similar collateral
will be considered reasonably conducted.
 
     Article 9 of the UCC provides that the proceeds of the sale will be applied
first to  pay the  costs  and expenses  of  the sale  and  then to  satisfy  the
indebtedness   secured  by  the  lender's  security  interest.  The  recognition
agreement, however, generally provides that the lender's right to  reimbursement
is  subject  to the  right  of the  Cooperative to  receive  sums due  under the
proprietary lease or occupancy agreement.  If there are proceeds remaining,  the
lender  must account to the tenant-stockholder for the surplus. Conversely, if a
portion of the indebtedness remains unpaid, the tenant-stockholder is  generally
responsible  for  the  deficiency. See  'Anti-Deficiency  Legislation  and Other
Limitations on Lenders' below.
 
     In the case of foreclosure on a building which was converted from a  rental
building  to a building owned  by a Cooperative under  a non-eviction plan, some
states require that a purchaser at a foreclosure sale take the property  subject
to  rent control and rent stabilization laws  which apply to certain tenants who
elected to  remain in  the  building but  who did  not  purchase shares  in  the
Cooperative when the building was so converted.
 
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
 
                                       53
 
<PAGE>
<PAGE>
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  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,
 
                                       54
 
<PAGE>
<PAGE>
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  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 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.

<PAGE>
     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 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.
 
                                       58

<PAGE>
     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 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
 
                                       59
 
<PAGE>
<PAGE>
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 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
 
                                       61
 
<PAGE>
<PAGE>
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 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.
 
                                       62
 
<PAGE>
<PAGE>
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 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
 
                                       63
 
<PAGE>
<PAGE>
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 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
 
                                       64
 
<PAGE>
<PAGE>
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, 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
 
                                       65
 
<PAGE>
<PAGE>
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
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
 
                                       66
 
<PAGE>
<PAGE>
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
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  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
 
                                       68
 
<PAGE>
<PAGE>
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 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
 
                                       69
 
<PAGE>
<PAGE>
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
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.
 
     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.
 
     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
 
                                       72
 
<PAGE>
<PAGE>
the  actual cost of  such Residual Certificate  to such holder  and the adjusted
basis such Residual Certificate would have in the hands of an original  Residual
Certificateholder,  see  ' --  Allocation  of the  Income  of the  REMIC  to the
Residual Certificates' above.
 
     Net Losses of the REMIC.  The REMIC  will have a net loss for any  calendar
quarter  in which its deductions exceed its gross income. Such net loss would be
allocated among  the  Residual Certificateholders  in  the same  manner  as  the
REMIC's  taxable income. The net loss allocable to any Residual Certificate will
not be deductible by the  holder to the extent that  such net loss exceeds  such
holder's  adjusted basis in such Residual Certificate.  Any net loss that is not
currently deductible  by reason  of this  limitation may  only be  used by  such
Residual  Certificateholder to offset its share of the REMIC's taxable income in
future periods (but not otherwise).  The ability of Residual  Certificateholders
that  are individuals or closely  held corporations to deduct  net losses may be
subject to additional limitations under the Code.
 
     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
 
                                       73
 
<PAGE>
<PAGE>
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
 
                                       74
 
<PAGE>
<PAGE>
REMIC Regulations provides that a thrift institution may only offset its  excess
inclusion  income  with deductions  after it  has  first applied  its deductions
against income that is not excess inclusion income.
 
     In the case of any Residual  Certificates held by a real estate  investment
trust,   the  aggregate  excess   inclusions  with  respect   to  such  Residual
Certificates, reduced (but not below zero)  by the real estate investment  trust
taxable  income (within the meaning of Code Section 857(b)(2), excluding any net
capital gain),  will  be allocated  among  the  shareholders of  such  trust  in
proportion  to the dividends received by  such shareholders from such trust, and
any amount so allocated will be treated as an excess inclusion with respect to a
Residual  Certificate  as  if  held  directly  by  such  shareholder.  Regulated
investment companies, common trust funds and certain cooperatives are subject to
similar rules.
 
     Payments.   Any 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
 
                                       75
 
<PAGE>
<PAGE>
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
 
                                       76
 
<PAGE>
<PAGE>
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
 
                                       77

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 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
 
                                       78

<PAGE>
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  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 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');
 
                                       80
 
<PAGE>
<PAGE>
          (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.
 
     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
 
                                       81
 
<PAGE>
<PAGE>
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  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
 
                                       82

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.
 
     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.
