THE PRUDENTIAL HOME MORTGAGE SECURITIES COMPANY, INC. [LOGO]
 
                                     SELLER
 
               MORTGAGE PASS-THROUGH CERTIFICATES, SERIES 1992-14
         PRINCIPAL AND INTEREST PAYABLE MONTHLY, COMMENCING IN MAY 1996
 
                    VARIABLE RATE(1) CLASS A-14 CERTIFICATES
                     (1) ON THE CLASS A-14 NOTIONAL AMOUNT
                              -------------------
 
    The  Series 1992-14 Mortgage Pass-Through  Certificates (the "Series 1992-14
Certificates") are the Series 1992-14 Certificates described in the accompanying
Prospectus Supplement dated April 21, 1992 (the "Prospectus Supplement") and the
accompanying Prospectus  dated  April 8,  1992  (the "Prospectus").  The  Series
1992-14  Certificates consist of one class  of senior certificates (the "Class A
Certificates") and  two  classes  of subordinated  certificates  (the  "Class  M
Certificates"   and  "Class   B  Certificates,"   respectively).  The   Class  A
Certificates consist of fifteen subclasses (each, a "Subclass") of  Certificates
designated  as the Class A-1, Class A-2,  Class A-3, Class A-4, Class A-5, Class
A-6, Class A-7, Class A-8, Class A-9, Class A-10, Class A-11, Class A-12,  Class
A-13,  Class A-14 and Class  A-R Certificates. The Class  M Certificates are not
divided into subclasses. The Class B Certificates consist of four subclasses  of
certificates  designated as the  Class B-1, Class  B-2, Class B-3  and Class B-4
Certificates. Only the  Class A-14  Certificates are being  offered hereby.  The
Series  1992-14  Certificates evidence  in the  aggregate the  entire beneficial
ownership interest  in a  trust fund  (the "Trust  Estate") established  by  The
Prudential  Home Mortgage Securities Company, Inc. (the "Seller") and consisting
of a pool of fixed interest  rate, conventional, monthly pay, fully  amortizing,
one-  to four-family, residential first mortgage  loans having original terms to
stated maturity of approximately 30 years (the "Mortgage Loans"), together  with
certain related property. The Mortgage Loans are serviced by The Prudential Home
Mortgage  Company, Inc. (in its capacity  as servicer, the "Servicer," otherwise
"PHMC"). See "Description of  the Mortgage Loans" herein  and in the  Prospectus
Supplement and "Risk Factors and Special Considerations" herein.
 
    PROSPECTIVE  INVESTORS IN  THE CLASS  A-14 CERTIFICATES  SHOULD CONSIDER THE
FACTORS DISCUSSED UNDER "RISK FACTORS AND SPECIAL CONSIDERATIONS" HEREIN ON PAGE
S1-3.
 
    The credit  enhancement  for the  Series  1992-14 Certificates  is  provided
through  the  use of  a "shifting  interest" type  subordination, which  has the
effect of allocating all or  a disproportionate amount of principal  prepayments
and  other unscheduled receipts of principal to  the Class A Certificates for at
least nine  years  beginning  on  the  first  Distribution  Date.  See  "Summary
Information--Credit  Enhancement"  and "--Effects  of Prepayments  on Investment
Expectations," "Description  of  the  Certificates" and  "Prepayment  and  Yield
Considerations" in the Prospectus Supplement.
 
    THE  YIELD  TO  MATURITY  OF  THE CLASS  A-14  CERTIFICATES  WILL  BE HIGHLY
SENSITIVE TO THE RATE AND  TIMING OF PRINCIPAL PAYMENTS (INCLUDING  PREPAYMENTS)
ON  THE  MORTGAGE LOANS,  WHICH  MAY BE  PREPAID  AT ANY  TIME  WITHOUT PENALTY.
INVESTORS SHOULD CONSIDER THE  ASSOCIATED RISKS THAT  A FASTER THAN  ANTICIPATED
RATE  OF  PRINCIPAL  PAYMENTS  (INCLUDING PREPAYMENTS)  ON  THE  MORTGAGE LOANS,
PARTICULARLY THOSE MORTGAGE LOANS WITH A  HIGHER RATE OF INTEREST, COULD  RESULT
IN  AN ACTUAL  YIELD THAT  IS LOWER THAN  ANTICIPATED AND  THAT A  RAPID RATE OF
PAYMENTS IN RESPECT  OF PRINCIPAL  (INCLUDING PREPAYMENTS) COULD  RESULT IN  THE
FAILURE   OF  INVESTORS  TO   FULLY  RECOVER  THEIR   INITIAL  INVESTMENTS.  See
"Sensitivity of the Pre-Tax  Yield and Weighted Average  Life of the Class  A-14
Certificates"  herein and "Description of the Certificates--Principal (Including
Prepayments)" and  "Prepayment  and  Yield  Considerations"  in  the  Prospectus
Supplement and in the Prospectus.

the  Seller from the sale  of the Class A-14  Certificates will be approximately
1.91% of the Pool Scheduled Principal Balance as of the Distribution Date in May
1996 without  giving effect  to  partial principal  prepayments or  net  partial
liquidation  proceeds received on or after the Determination Date in April 1996,
plus accrued interest from April 1, 1996  to (but not including) April 4,  1996,

(CONTINUED FROM PREVIOUS PAGE)
 
    The   Class  A-14  Certificates  may  not  be  appropriate  investments  for
individual investors.  The  Class  A-14  Certificates  are  offered  in  minimum
denominations  of $119,089,000 initial  Class A-14 Notional  Amount as described
herein under "Description of the Certificates." Except as set forth below, it is
intended that the Class A-14 Certificates not be directly or indirectly held  or
beneficially   owned  by  any   person  in  amounts   lower  than  such  minimum
denomination. The  Class A-14  Certificates  may be  transferred to  persons  in
amounts lower than the minimum denomination but only if any such person delivers
to  the Trustee an affidavit concerning certain matters related to the financial
sophistication  and  net  worth  of   such  person.  See  "Description  of   the
Certificates"and  "Restrictions  on  Transfer of  the  Class  A-14 Certificates"
herein.
 
    There is currently no secondary market  for the Class A-14 Certificates  and
there  can be no assurance  that a secondary market will  develop or, if it does
develop, that it will provide Certificateholders with liquidity of investment at
any particular  time  or  for the  life  of  the Class  A-14  Certificates.  The
Underwriter  intends to act  as a market  maker in the  Class A-14 Certificates,
subject to applicable provisions of federal and state securities laws and  other
regulatory requirements, but is under no obligation to do so and any such market
making  may be  discontinued at  any time.  There can  be no  assurance that any
investor will be able to  sell a Class A-14 Certificate  at a price equal to  or
greater than the price at which such Certificate was purchased.
 
    Distributions  in respect of interest and of  principal are made on the 25th
day of each month, or if such 25th day  of the month is not a business day,  the
next  succeeding  business  day to  the  holders  of record  of  the  Class A-14
Certificates on the last business day of the preceding month, to the extent that
their allocable portion of the Pool  Distribution Amount (as defined herein)  is
sufficient therefor. Interest will accrue monthly on the Class A-14 Certificates
at  a per annum rate equal to the  weighted average of the Net Mortgage Interest
Rates (as defined  herein) of the  Mortgage Loans as  of the first  day of  such
period  minus 8.00%, on the Class A-14 Notional Amount (as defined herein), less
any Non-Supported  Interest  Shortfall  (as defined  herein)  and  other  losses
allocable  to  the  Class  A-14  Certificates  as  described  in  the Prospectus
Supplement under  "Description  of  the  Certificates--Interest."  The  Class  A
Subclass   Principal  Balance  of   the  Class  A-14   Certificates  as  of  the
Determination Date  in  April 1996  will  be  approximately $172.  The  Class  A
Subclass  Principal Balance  as of  the Determination Date  in May  1996 will be
equal to such balance as of the Determination Date in April 1996 reduced by  the
amount of any distributions or other reductions of principal on the Distribution
Date  in April 1996. Distributions in reduction  of the principal balance of the
Class A  Certificates will  be made  monthly  on each  Distribution Date  in  an
aggregate  amount equal to the Class A Principal Distribution Amount (as defined
in the  Prospectus  Supplement). Distributions  in  reduction of  the  principal
balance  of the  Class A  Certificates each  month will  be allocated  among the
Subclasses of Class  A Certificates in  the manner described  in the  Prospectus
Supplement   under  "Description   of  the   Certificates--Principal  (Including
Prepayments)." Distributions on  the Class  A-14 Certificates will  be made  pro
rata  among  Certificateholders  of  such  Subclass  based  on  their Percentage
Interests (as defined in the Prospectus Supplement).
 
    This Supplement does  not contain complete  information regarding the  Class
A-14  Certificates and  should be read  only in conjunction  with the Prospectus
Supplement and the Prospectus. Sales of  the Class A-14 Certificates may not  be
consummated  unless the purchaser  has received this  Supplement, the Prospectus
Supplement and  the  Prospectus. Capitalized  terms  used herein  that  are  not
otherwise  defined shall  have the meanings  ascribed thereto  in the Prospectus
Supplement or the Prospectus, as applicable.

                                    GENERAL
 
    The  following is  qualified in  its entirety  by reference  to the detailed
information appearing in the Prospectus  Supplement and in the Prospectus,  each
of  which should be read in  conjunction with this Supplement. Capitalized terms
used in  this Supplement  and not  otherwise defined  herein have  the  meanings
assigned  in  the Prospectus  Supplement  or in  the  Prospectus. See  "Index of
Significant Prospectus Supplement Definitions" in the Prospectus Supplement  and
"Index of Significant Definitions" in the Prospectus.
 
    The  Series 1992-14 Certificates were issued on May 27, 1992. The Class A-14
Certificates were not offered to the public  at the time of the issuance of  the
Series 1992-14 Certificates.
 
                    RISK FACTORS AND SPECIAL CONSIDERATIONS
 
YIELD CONSIDERATIONS
 
    The  yield  to maturity  of  the Class  A-14  Certificates will  be directly
related to the rate of payments of principal on the Mortgage Loans in the  Trust
Estate,  particularly with respect to those  Mortgage Loans with higher rates of
interest. The rate of principal payments on  the Mortgage Loans will in turn  be
affected  by  the amortization  schedules  of the  Mortgage  Loans, the  rate of
principal prepayments (including  partial prepayments and  those resulting  from
refinancing)  thereon by  mortgagors, liquidations of  defaulted Mortgage Loans,
repurchases  by  the  Seller  of  Mortgage  Loans  as  a  result  of   defective
documentation or breaches of representations and warranties, optional repurchase
by  the Seller of defaulted Mortgage Loans and optional purchase by the Servicer
of all of the  Mortgage Loans in  connection with the  termination of the  Trust
Estate. See "Description of the Mortgage Loans--Optional Repurchase of Defaulted
Mortgage  Loans" and "Pooling and  Servicing Agreement--Optional Termination" in
the Prospectus Supplement and "The Trust Estates--Mortgage Loans--Assignment  of
Mortgage  Loans to the  Trustee," "--Optional Repurchases"  and "The Pooling and
Servicing Agreement--Termination; Purchase of Mortgage Loans" in the Prospectus.
Mortgagors are permitted to prepay the Mortgage  Loans, in whole or in part,  at
any time without penalty.
 
    The  rate of payments (including prepayments)  on pools of mortgage loans is
influenced by a variety  of economic, geographic, social  and other factors.  If
prevailing  rates for  similar mortgage loans  fall below  the Mortgage Interest
Rates on the Mortgage Loans, the rate of prepayment would generally be  expected
to  increase. Conversely, if interest rates on similar mortgage loans rise above
the Mortgage Interest Rates on the Mortgage Loans, the rate of prepayment  would
generally be expected to decrease.
 
    The  yield to maturity on the Class A-14 Certificates may be affected by the
geographic concentration  of  the  Mortgaged Properties  securing  the  Mortgage
Loans.  As  of March  15, 1996,  Mortgaged Properties  located in  the following
states secured at least 5.00% of  the Aggregate Unpaid Principal Balance of  the
Mortgage  Loans: California (54.96%), New York  (11.53%) and New Jersey (9.35%).
In recent years, California and several other regions in the United States  have
experienced  significant declines in housing prices. In addition, California, as
well as  certain other  regions, has  experienced natural  disasters,  including
earthquakes,  hurricanes  and  flooding,  which  may  adversely  affect property
values. Any direct damage to the Mortgaged Properties caused by such  disasters,
deterioration  in housing prices in California (and to a lesser extent the other
states in which the  Mortgaged Properties are located)  or the deterioration  of
economic  conditions  in such  regions which  adversely  affects the  ability of
borrowers to make payments on the Mortgage Loans may increase the likelihood  of
losses  on the  Mortgage Loans.  Such losses,  if they  occur, may  increase the
likelihood of liquidations and prepayments which  may have an adverse effect  on
the  yield to maturity of  the Class A-14 Certificates.  See "Description of the
Mortgage Loans" herein.
 
    AN INVESTOR THAT PURCHASES CLASS A-14 CERTIFICATES, WHICH ARE EXPECTED TO BE
OFFERED AT A SUBSTANTIAL  PREMIUM, SHOULD CONSIDER THE  RISK THAT A FASTER  THAN
ANTICIPATED  RATE OF PRINCIPAL PAYMENTS ON THE  MORTGAGE LOANS WILL RESULT IN AN
ACTUAL YIELD THAT IS LOWER THAN SUCH INVESTOR'S EXPECTED YIELD AND MAY RESULT IN
THE FAILURE  OF SUCH  INVESTOR  TO FULLY  RECOVER  ITS INITIAL  INVESTMENT.  See
"Sensitivity  of the Pre-Tax Yield  and Weighted Average Life  of the Class A-14
Certificates" herein and "Prepayment and Yield Considerations" in the Prospectus
Supplement.

RECENT DEVELOPMENTS AFFECTING THE SELLER AND SERVICER
 
    The Seller and  the Servicer are  each either a  direct or indirect,  wholly
owned  subsidiary of  Residential Services  Corporation of  America, which  is a
direct, wholly owned subsidiary of The Prudential Insurance Company of  America,
a  mutual insurance company organized under the  laws of the State of New Jersey
("Prudential Insurance"). On  January 29, 1996,  Prudential Insurance  announced
that it had entered into a definitive agreement (the "Sale Agreement") to sell a
substantial  portion of its residential mortgage operations to Norwest Mortgage,
Inc., a California corporation ("Norwest Mortgage"), and Norwest Bank  Minnesota
National  Association,  a  national  banking  association  ("Norwest  Bank" and,
collectively with Norwest Mortgage, "Norwest"). In connection therewith, on  the
closing  date specified pursuant to the  Sale Agreement (the "Sale Date"), which
is currently expected to be  on or about April  30, 1996, Norwest Mortgage  will
acquire  from the Servicer substantially all of its assets and businesses, other
than certain mortgage loans and the  Servicer's right to service mortgage  loans
underlying  series of mortgage  pass-through certificates representing interests
in trusts formed by the Seller or by Securitized Asset Sales, Inc., an affiliate
of the Seller  and the Servicer  ("SASI"), including the  Mortgage Loans in  the
Trust  Estate, and certain  other mortgage servicing  rights (all such servicing
rights collectively, the "Retained Servicing").  It is the present intention  of
the  Servicer  to sell  the  Retained Servicing,  from  time to  time  as market
conditions warrant, in one or more transactions to one or more purchasers, which
may include  Norwest  Mortgage,  and  to  effectively  exit  the  mortgage  loan
origination and servicing business as of the Sale Date.
 
    In order to assure the performance of the Servicer's obligations as servicer
under  the Pooling and  Servicing Agreement as  well as under  other pooling and
servicing agreements pursuant to which  various series of the Seller's  mortgage
pass-through certificates were issued and other agreements pursuant to which the
Servicer  performs Retained Servicing with  respect to mortgage loans underlying
series of mortgage  pass-through certificates representing  interests in  trusts
formed  by the  Seller or  SASI (each, a  "Servicing Agreement")  and under each
other agreement pursuant to which the Servicer performs Retained Servicing  with
respect  to  mortgage  loans  not  underlying  series  of  mortgage pass-through
certificates representing  interests in  trusts  formed by  the Seller  or  SASI
(each,  an "Other Servicing Agreement"),  the Servicer, Prudential Insurance and
Norwest intend to enter into the following arrangements:
 
    1.  SUBSERVICING AGREEMENT.  The Servicer, Prudential Insurance and  Norwest
Mortgage   will  enter   into  a   subservicing  agreement   (the  "Subservicing
Agreement"), pursuant to which the  Servicer will delegate to Norwest  Mortgage,
and  Norwest Mortgage will  agree to perform,  all of the  Servicer's duties and
obligations as mortgage loan servicer under the Pooling and Servicing  Agreement
and  each  Servicing Agreement  and Other  Servicing  Agreement, other  than the
Servicer's duties with  respect to  the administration and  disposition of  real
estate   acquired  upon  foreclosure,  which   latter  duties  will  remain  the
responsibility of the Servicer with the particular functions to be delegated  by
the Servicer to Prudential Asset Recovery, Inc., an affiliate of the Seller, the
Servicer,  SASI and Prudential Insurance, or other third party contractors. With
respect to the Series  1992-14 Certificates, such  duties include collection  of
mortgage  payments,  maintenance of  tax  and insurance  escrows,  advancing for
borrower delinquencies and unpaid taxes, to  the extent required by the  Pooling
and  Servicing  Agreement, and  foreclosure or  other realization  activities in
connection with defaulted Mortgage Loans.
 
    Under the Subservicing Agreement, Norwest Mortgage will be obligated to make
any principal and interest or other advances required to be made by the Servicer
under the  Pooling and  Servicing  Agreement as  well  as under  each  Servicing
Agreement or Other Servicing Agreement, provided that the aggregate unreimbursed
amount  of such advances at any time  does not exceed $100 million. The Servicer
will be  obligated to  reimburse Norwest  Mortgage for  the amount  of any  such
advances,  plus interest, from its own funds. The Servicer will remain obligated
under the Pooling and Servicing Agreement and each Servicing Agreement and Other
Servicing Agreement for  all required  advances which  are not  made by  Norwest
Mortgage for any reason. In order to provide for its obligation to make advances
after  the  Sale  Date, the  Servicer  will  enter into  a  Loan  Agreement with
Prudential Funding Corporation, an affiliate  of the Seller, the Servicer,  SASI
and Prudential Insurance ("Funding"), pursuant to which Funding will provide the
Servicer  with a committed borrowing line (the "Loan Facility") in the amount of
$40 million for the sole purpose of supporting advances required of the Servicer
under the Pooling and Servicing Agreement and Servicing Agreements. Although the
Servicer  expects   that  the   combination   of  Norwest   Mortgage's   advance
 
                                      S1-4
<PAGE>
obligation  under  the  Subservicing Agreement  and  the Loan  Facility  will be
adequate to provide for the continuation of  all such advances, there can be  no
assurance  that such mechanisms will be sufficient,  or that after the Sale Date
the Servicer will  have sufficient  other assets,  to ensure  that all  required
advances will be made.
 
    The Servicer will pay Norwest Mortgage a portion of the Servicer's servicing
compensation  under the  Pooling and Servicing  Agreement for  its activities as
subservicer. The Subservicing Agreement will have an initial term of five  years
from  the Sale Date and may be extended  for consecutive three year terms by the
Servicer, at its option, provided that the Servicer and Norwest Mortgage  agree,
in  the exercise of good  faith, on the subservicing  compensation for each such
renewal term. The  Subservicing Agreement  will be terminable  by the  Servicer,
from  time to time, with respect to any  Mortgage Loans as to which the Servicer
arranges to sell the Retained Servicing.
 
    2.  CERTIFICATE  ADMINISTRATION AGREEMENT.   The Servicer  and Norwest  Bank
will  enter  into  an agreement  (the  "Certificate  Administration Agreement"),
pursuant to which the Servicer will  delegate to Norwest Bank, and Norwest  Bank
will  agree  to  perform, all  of  the  Servicer's obligations  with  respect to
administrative  and  reporting  functions   under  the  Pooling  and   Servicing
Agreement.  Such duties  include calculation  of distributions,  preparation and
filing of tax returns, preparation of  reports to investors and preparation  and
filing  of  periodic  reports under  the  Securities  Exchange Act  of  1934, as
amended.
 
    The Subservicing Agreement and the Certificate Administration Agreement will
collectively provide for the delegation  of substantially all of the  Servicer's
duties  and obligations  under the  Pooling and  Servicing Agreement.  While the
Pooling and Servicing Agreement  provides that the  Servicer will remain  liable
for   its  obligations  thereunder  until  the  related  Retained  Servicing  is
transferred in the manner  permitted thereby, from and  after the Sale Date  the
Servicer  is not  expected to  have any  servicing capability  or employees with
which to perform such obligations.
 
    Under the  Pooling and  Servicing Agreement,  the Seller  is required,  with
respect to any Mortgage Loan found to have defective documentation or in respect
of  which  the  Seller has  breached  a  representation or  warranty,  either to
repurchase such Mortgage  Loan or to  substitute a new  mortgage loan  therefor.
Each  such Mortgage Loan was, in turn,  acquired by the Seller from the Servicer
pursuant to an agreement under which  the Servicer is required to repurchase  or
substitute  for any such Mortgage Loan so  repurchased or substituted for by the
Seller. Although  after the  Sale Date  the Servicer  will continue  to own  the
Retained  Servicing,  the Servicer  intends to  sell  the Retained  Servicing as
expeditiously  as  market  conditions  permit.  Accordingly,  there  can  be  no
assurance  that  at any  time after  the Sale  Date the  Servicer will  have any
material assets with which  to satisfy such obligations  to the Seller. In  such
event,  the Seller  would be  unable to  fulfill its  repurchase or substitution
obligations under the Pooling and  Servicing Agreement. However with respect  to
any Mortgage Loan subserviced pursuant to the Subservicing Agreement, Prudential
Insurance  will  agree in  the Subservicing  Agreement to  provide the  funds to
repurchase such Mortgage Loan.
 
    According to information provided by Norwest Mortgage, at December 31, 1995,
Norwest Mortgage  was  the  nation's  largest  mortgage  originator  and  had  a
servicing  portfolio  of  more  than $107  billion.  In  1995,  Norwest Mortgage
originated over $33 billion of residential mortgage loans. Headquartered in  Des
Moines,  Iowa, Norwest Mortgage has more than 700 loan production offices in all
50 states.  While derived  from sources  believed to  be reliable,  neither  the
Seller,  the Servicer nor  the Underwriter makes  any representation or warranty
regarding the  accuracy or  completeness of  the information  contained in  this
paragraph.

                        DESCRIPTION OF THE CERTIFICATES
 
    The   Class  A-14  Certificates   will  be  offered   in  fully  registered,
certificated form in  minimum denominations of  $119,089,000 initial Class  A-14
Notional  Amount; provided,  however, that  the Class  A-14 Certificates  may be
issued in minimum denominations of $5,539,000 initial Class A-14 Notional Amount
to persons who  deliver to the  Trustee an affidavit  stating that such  person:
(a)(i)  is a substantial, sophisticated, institutional investor having knowledge
and experience in  financial and  business matters,  and in  particular in  such
matters  related to securities similar to the Class A-14 Certificates, such that
such investor is capable of evaluating the merits and risks of an investment  in

reductions of principal on the Distribution Date in April 1996.
 
    Distributions of interest and in  reduction of principal balance to  holders
of Class A-14 Certificates will be made monthly, to the extent of such Subclass'
entitlement  thereto, on the  25th day of  each month or,  if such day  is not a
business day,  on the  succeeding business  day (each,  a "Distribution  Date"),
beginning in May 1996.
 
    Distributions  (other than the final distribution in retirement of the Class
A-14 Certificates, as described  in the Prospectus Supplement)  will be made  by
check  mailed to the address of the person entitled thereto as it appears on the
Certificate Register.  However,  with  respect  to  any  holder  of  Class  A-14
Certificates  evidencing at least a  25% Percentage Interest, distributions will
be made  on the  Distribution Date  by wire  transfer in  immediately  available
funds,  provided that the Servicer, or the  paying agent acting on behalf of the
Servicer, shall have  been furnished  with appropriate  wiring instructions  not
less than seven business days prior to the related Distribution Date.
 
    The Class A-14 Certificates will be entitled to a distribution in respect of
interest  each month in an amount up to such Subclass' Class A Subclass Interest
Accrual Amount. The Class A Subclass Interest Accrual Amount for the Class  A-14
Certificates  will equal the product of (i) 1/12th of the difference between (a)
the weighted average of  the Net Mortgage Interest  Rates of the Mortgage  Loans
(based  on the  Scheduled Principal  Balances of the  Mortgage Loans  as of such
Distribution Date) and (b) 8.00% and (ii) the Class A-14 Notional Amount.
 
    The Class A Subclass Interest Accrual Amount for the Class A-14 Certificates
will be  reduced by  the portion  of (i)  any Non-Supported  Interest  Shortfall
allocable  to  such Subclass  and (ii)  the interest  portion of  Excess Special
Hazard Losses, Excess  Fraud Losses  and Excess Bankruptcy  Losses allocable  to
such  Subclass as described under "Description of the Certificates--Interest" in
the Prospectus Supplement.
 
    The "Net  Mortgage Interest  Rate" on  each Mortgage  Loan is  equal to  the
Mortgage  Interest Rate on such Mortgage Loan  as stated in the related Mortgage
Note minus the Servicing Fee rate of 0.25% per annum. See "Pooling and Servicing
Agreement--Servicing Compensation  and Payment  of Expenses"  in the  Prospectus
Supplement.
 
    The "Class A-14 Notional Amount" with respect to each Distribution Date will
be  equal to the Pool Scheduled Principal Balance, as defined under "Description
of  the  Certificates--Principal  (Including  Prepayments)"  in  the  Prospectus
Supplement,  as of such  Distribution Date. The Class  A-14 Notional Amount with
respect to the Distribution Date  in March 1996 was approximately  $115,237,609.
The Class A-14 Notional Amount with respect to the Distribution Date in May 1996
will be equal to the Class A-14 Notional Amount with respect to the Distribution
Date  in March  1996, less the  difference between the  Pool Scheduled Principal
Balance with  respect  to the  Distribution  Date in  March  1996 and  the  Pool
Scheduled Principal Balance with respect to the Distribution Date in May 1996. A
notional  amount does not entitle a holder to receive distributions of principal
on the basis  of such notional  amount, but is  solely used for  the purpose  of
computing  the amount of interest accrued on  a Subclass. The initial Class A-14
Notional Amount was approximately $476,354,867.
 
    Notwithstanding anything  contained  in  the Prospectus  Supplement  or  the
Prospectus  to the contrary,  the "Pool Distribution  Amount" for a Distribution
Date will be the sum of all previously undistributed payments or other  receipts
on  account  of  principal  (including  principal  prepayments  and  Liquidation
Proceeds in respect of principal,
 
                                      S1-6

if any) and  interest on or  in respect of  the Mortgage Loans  received by  the
Servicer  after the  Cut-Off Date  (except for  amounts due  on or  prior to the
Cut-Off Date), or received by the Servicer  on or prior to the Cut-Off Date  but
due  after the Cut-Off Date, in either case received on or prior to the business
day preceding the  Determination Date in  the month in  which such  Distribution
Date  occurs, plus (i) all  Periodic Advances made by  the Servicer and (ii) all
other amounts required to be placed  in the Certificate Account by the  Servicer
pursuant to the Pooling and Servicing Agreement, but excluding the following:
 
        (a)   amounts  received  as  late  payments  of  principal  or  interest
    respecting which the Servicer previously  has made one or more  unreimbursed
    Periodic Advances;
 
        (b) any unreimbursed Periodic Advances with respect to Liquidated Loans;
 
        (c)  those portions of each payment of interest on a particular Mortgage
    Loan which represent the applicable Servicing Fee, as adjusted in respect of
    Prepayment Interest  Shortfalls  as  described  under  "Description  of  the
    Certificates--Interest" in the Prospectus Supplement;
 
        (d)  all  amounts  representing  scheduled  payments  of  principal  and
    interest due  after  the Due  Date  occurring in  the  month in  which  such
    Distribution Date occurs;
 
        (e)  all principal prepayments in full  and all proceeds of any Mortgage
    Loans, or  property acquired  in  respect thereof,  liquidated,  foreclosed,
    purchased  or repurchased pursuant  to the Pooling  and Servicing Agreement,
    received on or  after the  Due Date  occurring in  the month  in which  such
    Distribution  Date occurs, and all partial principal prepayments received by
    the Servicer on or  after the Determination Date  occurring in the month  in
    which such Distribution Date occurs, and all related payments of interest on
    such amounts;
 
         (f)  to the  extent permitted by  the Pooling  and Servicing Agreement,
    that portion of Liquidation Proceeds or insurance proceeds with respect to a
    Mortgage Loan  which  represents  any  unpaid Servicing  Fee  to  which  the
    Servicer is entitled;
 
        (g)  all  amounts  representing  certain  expenses  reimbursable  to the
    Servicer and  other amounts  permitted to  be retained  by the  Servicer  or
    withdrawn  by  the Servicer  from the  Certificate  Account pursuant  to the
    Pooling and Servicing Agreement;
 
        (h) all amounts in the nature of late fees, assumption fees,  prepayment
    fees and similar fees which the Servicer is entitled to retain as additional
    servicing compensation;
 
         (i)  reinvestment  earnings  on  payments received  in  respect  of the
    Mortgage Loans; and
 
         (j) Net Foreclosure Profits.
 
    Notwithstanding anything  contained  in  the Prospectus  Supplement  or  the
Prospectus to the contrary, if, on any Determination Date, payments of principal
and  interest due on  any Mortgage Loan in  the Trust Estate  on the related Due
Date have not  been received as  of the close  of business on  the business  day
preceding  such  Determination  Date, the  Servicer  will be  obligated  to make
Periodic Advances on or before the related Distribution Date for the benefit  of
holders of the Series 1992-14 Certificates.
 
    Notwithstanding  anything in the Prospectus  Supplement or the Prospectus to
the contrary, "Prepayment Interest Shortfalls"  will consist of both  shortfalls
in  collections of  interest as  a result  of principal  prepayments in  full of
Mortgage Loans and as a result of the timing of partial prepayments.  Prepayment
Interest Shortfalls will be offset to the extent of the aggregate Servicing Fees
relating  to mortgagor payments  or other recoveries  distributed on the related
Distribution  Date.  To  the  extent  that  the  aggregate  Prepayment  Interest
Shortfalls  with respect to  a Distribution Date  exceed the aggregate Servicing
Fees relating  to mortgagor  payments or  other recoveries  distributed on  such
Distribution Date, the resulting interest shortfall (the "Non-Supported Interest
Shortfall")   will  be  allocated   as  described  under   "Description  of  the
Certificates--Interest" in the Prospectus Supplement.
 
    As described under "Pooling  and Servicing Agreement--Optional  Termination"
in  the Prospectus Supplement, the Servicer has  the right, but is not required,
to purchase from  the Trust  Estate all  remaining Mortgage  Loans, and  thereby
effect  early retirement of the Series 1992-14 Certificates, on any Distribution
Date when the Pool Scheduled Principal Balance  is less than 10% of the  Cut-Off
Date Aggregate Principal Balance (as defined in the
 
                                      S1-7
<PAGE>
Prospectus Supplement). However, the Servicer will agree that for so long as the
Class  A-14  Certificates are  outstanding, without  the  consent of  holders of
66 2/3% Percentage Interest  of the Class A-14  Certificates, the Servicer  will
not  exercise  such right  unless the  Pool Scheduled  Principal Balance  of the
Mortgage Loans  is equal  to  or less  than 1%  of  the Cut-Off  Date  Aggregate
Principal Balance.
 
    The  Prospectus Supplement and the Prospectus contain significant additional
information concerning  the  characteristics  of the  Class  A-14  Certificates.
Investors  are urged to read "Description of the Certificates" in the Prospectus
Supplement and in the Prospectus.

                       DESCRIPTION OF THE MORTGAGE LOANS
 
    As  of March 15, 1996,  the Mortgage Loans in  the Trust Estate consisted of
fixed interest  rate,  conventional,  monthly pay,  fully  amortizing,  one-  to
four-family, residential first mortgage loans originated or acquired by PHMC for
its  own account  or for the  account of  an affiliate having  original terms to
stated maturity of approximately 30 years.  The "Unpaid Principal Balance" of  a
Mortgage  Loan as of March  15, 1996 is its unpaid  principal balance as of such
date assuming no delinquencies and no prepayments in full. As of March 15, 1996,
the Mortgage Loans  included 532  promissory notes, having  an aggregate  Unpaid
Principal  Balance (the  "Aggregate Unpaid Principal  Balance") of approximately
$113,353,836, secured by first  liens (the "Mortgages")  on one- to  four-family
residential  properties (the  "Mortgaged Properties"). As  of March  15, 1996 no
such Mortgage Loans have prepaid in full. Prepayments in full occurring in March
1996 will reduce the Class A-14 Notional Amount with respect to the Distribution
Date in  May  1996.  The  Mortgage Loans  have  the  additional  characteristics
described below and in the Prospectus.
 
    No Mortgage Loan is a Buy-Down Loan. See "The Trust Estates--Mortgage Loans"
in the Prospectus. No Mortgage Loan was originated pursuant to PHMC's Relocation
Mortgage   Program.  See   "PHMC--Mortgage  Loan  Production   Sources"  in  the
Prospectus.
 
    Each of the Mortgage Loans is subject to a due-on-sale clause. See  "Certain
Legal Aspects of the Mortgage Loans--'Due-on-Sale' Clause" and "Servicing of the
Mortgage  Loans--Enforcement of Due-on-Sale  Clauses; Realization Upon Defaulted
Mortgage Loans" in the Prospectus.
 
    As of March 15, 1996, each Mortgage Loan had an Unpaid Principal Balance  of
not  less than $20,030 or more than $1,421,009, and the average Unpaid Principal
Balance of  the Mortgage  Loans was  approximately $213,071.  The latest  stated
maturity  date of  any of  the Mortgage  Loans was  April 1,  2023; however, the
actual date on which any Mortgage Loan is  paid in full may be earlier than  the
stated  maturity  date  due  to  unscheduled  payments  of  principal.  Based on
information  supplied  by   the  mortgagors  in   connection  with  their   loan
applications  at  origination, 479  of  the Mortgaged  Properties,  which secure
approximately 94.64% of the Aggregate  Unpaid Principal Balance of the  Mortgage
Loans,   were  owner  occupied  primary  residences  and  53  of  the  Mortgaged
Properties, which secure approximately 5.36%  of the Aggregate Unpaid  Principal
Balance  of the  Mortgage Loans,  were non-owner  occupied or  second homes. See
"PHMC--Mortgage Loan Underwriting" in the Prospectus.
 
    As of March 15, 1996,  no Mortgage Loan was a  Subsidy Loan. See "The  Trust
Estates--Mortgage   Loans"  and   "PHMC--Mortgage  Loan   Underwriting"  in  the
Prospectus.

As  of  March  15,  1996,  the  minimum  and  maximum  Loan-to-Value  Ratios  at
origination  of the Mortgage  Loans were 20.1% and  90.0%, respectively, and the
weighted average Loan-to-Value Ratio  at origination of  the Mortgage Loans  was
approximately  72.1%. The Loan-to-Value  Ratio of a  Mortgage Loan is calculated
using the lesser of (i) the  appraised value of the related Mortgaged  Property,
as  established by an appraisal obtained by  the originator from an appraiser at
the time of  origination and  (ii) the  sale price  for such  property. In  some
instances,  the  Loan-to-Value  Ratio may  be  based  on an  appraisal  that was
obtained by the originator more than four months prior to origination,  provided
that  (i) a recertification of  the original appraisal is  obtained and (ii) the
original appraisal was obtained no more than twelve months prior to origination.
For the purpose of calculating the Loan-to-Value Ratio of any Mortgage Loan that
is the result of the refinancing (including a refinancing for "equity  take-out"
purposes)  of  an existing  mortgage loan,  the appraised  value of  the related
Mortgaged Property is generally determined by reference to an appraisal obtained
in connection  with the  origination of  the replacement  loan. See  "The  Trust
Estates--Mortgage  Loans" in the Prospectus.  As of March 15,  1996, nine of the
Mortgage Loans  having Loan-to-Value  Ratios at  origination in  excess of  80%,
representing  approximately 1.68% of  the Aggregate Unpaid  Principal Balance of
the Mortgage  Loans, were  originated without  primary mortgage  insurance.  See
"PHMC--Mortgage Loan Underwriting" in the Prospectus.

Documentation levels vary depending upon several factors, including loan amount,
Loan-to-Value Ratio and the type and purpose of the Mortgage Loan. Asset, income
and mortgage verifications were obtained for Mortgage Loans processed with "full
documentation." In the case of "preferred processing," neither asset, income nor
mortgage  verifications were obtained.  However, for all  of the Mortgage Loans,
verification of the borrower's employment, a credit report on the borrower and a
property appraisal were obtained. See "PHMC--Mortgage Loan Underwriting" in  the
Prospectus.

In general,  in the  case of  a  Mortgage Loan  made for  "rate/term"  refinance
purposes,  substantially  all  of the  proceeds  are  used to  pay  in  full the
principal balance of a previous mortgage loan of the mortgagor with respect to a
Mortgaged Property and to pay origination and closing costs associated with such
refinancing. However, in the case of a Mortgage Loan made for "equity take  out"
refinance  purposes, all or a portion of  the proceeds are generally retained by
the mortgagor for uses unrelated to  the Mortgaged Property. The amount of  such
proceeds   retained  by  the  mortgagor  may  be  substantial.  See  "The  Trust
Estates--Mortgage  Loans"  and   "PHMC--Mortgage  Loan   Underwriting"  in   the
Prospectus.

    principal balances of such Mortgage Loans based on information available  to
    the Servicer as of March 15, 1996.
 
(2) As of March 15, 1996.
 
The  indicated periods of delinquency are based  on the number of days past due,
based on a  30-day month. No  Mortgage Loan is  considered delinquent for  these
purposes until one month has passed since its contractual due date.
 
    On  January  17, 1994,  southern California  experienced an  earthquake (the
"Earthquake") and  thereafter  a number  of  aftershocks.  As a  result  of  the
Earthquake,  Los Angeles and  Ventura Counties (the  "Earthquake Counties") were
declared federal disaster  areas eligible  for federal  disaster assistance.  In
addition  to the Earthquake  Counties, other counties may  have been affected by
the Earthquake. As  of March  15, 1996,  approximately 27.37%  of the  Aggregate
Unpaid  Principal  Balance  of  the  Mortgage  Loans  was  secured  by Mortgaged
Properties

physical  inspection of any Mortgaged  Properties. As a result,  there can be no
assurance that material damage to any Mortgaged Property in the affected  region
has not occurred.
 
    As  of January 16, 1995 and March 16,  1995, as a result of flooding, 38 and
49 counties in California, respectively, (the "January 1995 Flood Counties"  and
"March  1995  Flood  Counties,"  respectively,  and  together,  the  "1995 Flood
Counties") were declared  federal disaster areas  eligible for federal  disaster
assistance.  As of March 15, 1996,  approximately 53.14% of the Aggregate Unpaid
Principal Balance of the Mortgage Loans was secured by Mortgaged Properties that
are located in the January 1995  Flood Counties and approximately 49.08% of  the
Aggregate  Unpaid  Principal  Balance  of  the  Mortgage  Loans  was  secured by
Mortgaged Properties that  are located  in the  March 1995  Flood Counties.  The
Seller  has not undertaken the physical  inspection of any Mortgaged Properties.
As a result, there  can be no  assurance that material  damage to any  Mortgaged
Property in the affected region has not occurred.
 
    As  of  October 12,  1995, as  a  result of  a hurricane  affecting Georgia,
Alabama and  Florida (the  "Hurricane"), 28,  20 and  11 counties,  in  Georgia,
Alabama  and  Florida, respectively  (the  "Hurricane Counties"),  were declared
federal disaster areas eligible for federal disaster assistance. As of March 15,
1996, 2.02% of the Aggregate Unpaid Principal Balance of the Mortgage Loans  was
secured  by Mortgage Properties that are  located in the Hurricane Counties. The
Seller has not undertaken the  physical inspection of any Mortgaged  Properties.
As  a result, there  can be no  assurance that material  damage to any Mortgaged
Property in the affected region has not occurred.
 
    As of  March  8,  1996, as  a  result  of recent  flooding  (the  "Northeast
Floods"),  all counties in the Commonwealth of Pennsylvania, all counties in the
State of Maryland, 28 counties in the State of West Virginia, 28 counties in the
State of New York, 13 counties in  the Commonwealth of Virginia and 12  counties
in  the State  of Ohio  (the "Northeast  Flood Counties")  were declared federal
disaster areas eligible for federal disaster  assistance. As of March 15,  1996,
approximately  6.66% of the  Aggregate Unpaid Principal  Balance of the Mortgage
Loans was secured  by Mortgaged  Properties that  are located  in the  Northeast
Flood  Counties.  In  addition, other  counties  may  have been  and  may become
affected by the  Northeast Floods. The  Seller has not  undertaken the  physical
inspection  of any Mortgaged Properties. As a  result, there can be no assurance
that material damage to  any Mortgaged Property in  the affected region has  not
occurred.
 
    As  of February  28, 1996,  as a result  of recent  flooding (the "Northwest
Floods"), 26  counties in  the State  of Oregon,  21 counties  in the  State  of
Washington  and  10  counties  in  the  State  of  Idaho  (the  "Northwest Flood
Counties") were declared  federal disaster areas  eligible for federal  disaster
assistance.  As of March  15, 1996, approximately 0.62%  of the Aggregate Unpaid
Principal Balance of the Mortgage Loans was secured by Mortgage Properties  that
are  located in  the Northwest Flood  Counties. In addition,  other counties may
have been and may become  affected by the Northwest  Floods. The Seller has  not
undertaken  the physical  inspection of any  Mortgaged Properties.  As a result,
there can be no assurance that material damage to any Mortgaged Property in  the
affected region has not occurred.
 
    Based on information available to the Servicer as of March 15, 1996, sixteen
of  the delinquent  Mortgage Loans  shown in  the preceding  table, representing
approximately 4.75% of the  Aggregate Unpaid Principal  Balance of the  Mortgage
Loans  or approximately $5,386,963, were secured by Mortgaged Properties located
in the Earthquake Counties, the Hurricane Counties, the 1995 Flood Counties, the
Northeast Flood Counties or the Northwest Flood Counties.

              ORIGINATION, DELINQUENCY AND FORECLOSURE EXPERIENCE
 
    During the years ended December 31, 1993, December 31, 1994 and December 31,
1995, PHMC originated or purchased, for its own account or for the account of an
affiliate, conventional mortgage loans having an aggregate principal balance  of
approximately $35,805,498,813, $16,201,648,701 and $11,488,362,184,
respectively.
 
    The   following  tables  reflect  delinquency,  foreclosure  and  loan  loss
experience of mortgage loans serviced by PHMC. As described under "Risk  Factors
and  Special Considerations--Recent Developments," PHMC  intends, as of the Sale
Date, to cease  its mortgage  loan origination and  servicing business.  Norwest
Mortgage,   as  subservicer  for  PHMC,   will  perform  foreclosure  and  other
realization  activities  in  connection   with  defaulted  Mortgage  Loans   and
Prudential   Asset  Recovery,  Inc.  or  another  third  party  contractor  will
administer and dispose of real estate acquired upon foreclosure.
 
    Certain information concerning PHMC's delinquency, foreclosure and loan loss
experience on  certain  categories of  the  mortgage loans  included  in  PHMC's
mortgage  loan  servicing  portfolio  for the  years  ended  December  31, 1990,
December 31, 1991  and the three  months ended March  31, 1992 is  set forth  in
"Origination,    Delinquency   and   Foreclosure   Experience--Delinquency   and
Foreclosure Experience" in the Prospectus  Supplement. The following tables  set
forth  such information as of December 31,  1993, December 31, 1994 and December

                             HISTORICAL PREPAYMENTS
 
    The prepayment  model used  in  the Prospectus  Supplement is  the  Standard
Prepayment  Assumption ("SPA"). See "Prepayment and Yield Considerations" in the
Prospectus Supplement. An alternative  model is a conditional  (also known as  a
constant)  prepayment  rate  ("CPR").  CPR  represents  a  rate  of  payment  of
unscheduled principal on mortgage loans,  expressed as an annualized  percentage
of  the outstanding principal balance of such mortgage loans at the beginning of
each period. CPR DOES NOT PURPORT  TO BE A HISTORICAL DESCRIPTION OF  PREPAYMENT
EXPERIENCE  OR A PREDICTION OF THE ANTICIPATED RATE OF PREPAYMENT OF ANY POOL OF
MORTGAGE LOANS, INCLUDING THE MORTGAGE LOANS.
 
    The Series 1992-14 Certificates were issued on May 27, 1992. Set forth below
are the approximate annualized prepayment rates of the Mortgage Loans underlying
the Series 1992-14 Certificates  as a percentage of  CPR as of the  Distribution
Dates occurring in the indicated months.

</TABLE>
 
    The prepayment rates described above were calculated based upon the weighted
average  Mortgage Interest Rate  of the Mortgage Loans  for the applicable month
and an assumed  weighted average  remaining term  to maturity  for the  Mortgage
Loans  equal to the weighted  average remaining term to  maturity at the date of
the initial issuance  of the Series  1992-14 Certificates with  respect to  June
1992,  reduced by one month for each month thereafter. The prepayment history of
the Mortgage  Loans underlying  the Series  1992-14 Certificates  is  relatively
short  and cannot be relied  upon as an indicator of  the rate of prepayments on
the  Mortgage  Loans  to  be  experienced  over  the  life  of  the  Class  A-14
Certificates. Further, the rate of prepayment of a pool of mortgage loans during
any period should be considered in light of the amount of time elapsed since the
origination  of such mortgage loans and the  absolute levels of, and changes in,
prevailing market interest rates during such period. For a further discussion of
the factors affecting the rate of prepayments on mortgage loans, see "Prepayment
and Yield Considerations" in the  Prospectus Supplement. INVESTORS ARE URGED  TO
MAKE  AN INDEPENDENT DECISION AS TO THE APPROPRIATE PREPAYMENT ASSUMPTIONS TO BE
USED IN DECIDING WHETHER TO PURCHASE A CLASS A-14 CERTIFICATE.

concerning factors that will affect the  yield and weighted average life of  the
Class  A-14  Certificates. Investors  are urged  to  read "Prepayment  and Yield
Considerations" in the Prospectus Supplement and the Prospectus.
 
    THE YIELD TO INVESTORS IN THE CLASS A-14 CERTIFICATES, WHICH ARE EXPECTED TO
BE OFFERED AT A SUBSTANTIAL PREMIUM, WILL BE HIGHLY SENSITIVE TO BOTH THE TIMING
OF RECEIPT OF PREPAYMENTS  AND THE OVERALL RATE  OF PRINCIPAL PREPAYMENT ON  THE
MORTGAGE  LOANS, PARTICULARLY WITH  RESPECT TO THOSE  MORTGAGE LOANS WITH HIGHER
RATES OF INTEREST, WHICH OVERALL RATE  MAY FLUCTUATE SIGNIFICANTLY FROM TIME  TO
TIME.  AN  INVESTOR IN  THE CLASS  A-14 CERTIFICATES  SHOULD FULLY  CONSIDER THE
ASSOCIATED RISKS, INCLUDING  THE RISK THAT  A RAPID RATE  OF PRINCIPAL  PAYMENTS
(INCLUDING  PREPAYMENTS) COULD RESULT  IN THE FAILURE OF  SUCH INVESTOR TO FULLY
RECOVER ITS INITIAL INVESTMENT.
 
    For purposes of the table  set forth below, the  weighted average life of  a
Class A-14 Certificate is the average amount of time that will elapse from April
4,  1996 until each dollar  in reduction of the  principal balance of the Series
1992-14 Certificates is distributed to the holders thereof. The weighted average
life of the Class A-14 Certificates  will be influenced by, among other  things,
the rate and timing of principal payments on the Mortgage Loans, which may be in
the form of scheduled amortization or prepayments.
 
    The following table has been prepared on the basis of the characteristics of
the  Mortgage  Loans included  in  the Trust  Estate as  of  March 15,  1996, as
described above under "Description of  the Mortgage Loans," adjusted to  reflect
calculated payments of principal on April 1, 1996 assuming a constant prepayment
rate equal to 0% CPR for the month of March 1996. This adjustment has the effect
of  reducing the remaining terms to stated maturity of each Mortgage Loan by one
month from the table shown on page S1-11. The table indicates the sensitivity to
various rates  of prepayment  on the  Mortgage  Loans of  the pre-tax  yield  to
maturity,  on a  corporate bond  equivalent ("CBE")  basis, and  of the weighted
average life of the Class A-14 Certificates at various percentages of CPR.  Such
calculations  are based on distributions made in accordance with "Description of
the Certificates" herein and  in the Prospectus  Supplement, on the  assumptions
described  in clauses (i), (iii) and (v)  of the fourth full paragraph beginning
on page S-50 of the Prospectus  Supplement, and on the further assumptions  that
(i)  the  Class A-14  Certificates will  be purchased  on April  4, 1996  for an
aggregate purchase  price  equal  to approximately  $2,209,247,  which  includes
accrued  interest from April 1, 1996 to  (but not including) April 4, 1996, (ii)
distributions to holders of Class A-14 Certificates will be made on the 25th day
of each  month commencing  in  May 1996,  (iii)  scheduled monthly  payments  of
principal  and interest  on the  Mortgage Loans will  be timely  received on the
first day  of  each  month (with  no  defaults)  commencing in  May  1996,  (iv)
principal  prepayments on the Mortgage Loans will be received on the last day of
each month commencing  in April 1996  at the respective  percentages of CPR  set
forth  in the  table and  there are no  Prepayment Interest  Shortfalls, (v) the
Class A-14 Notional Amount applicable to the Distribution Date occurring in  May
1996  will be approximately $113,262,596 and (vi) the Class A Subclass Principal
Balance of the Class A-14 Certificates as of the Determination Date occurring in
May 1996 will be approximately $171.
 
           SENSITIVITY OF THE PRE-TAX YIELD AND WEIGHTED AVERAGE LIFE

</TABLE>
 
    The pre-tax yields set forth in  the preceding table were calculated by  (i)
determining the monthly discount rates which, when applied to the assumed stream
of  cash  flows to  be  paid on  the Class  A-14  Certificates, would  cause the
discounted present  value of  such assumed  stream  of cash  flows to  equal  an
assumed  purchase  price  for  the  Class  A-14  Certificates  of  approximately
$2,209,247 which  includes accrued  interest  from April  1,  1996 to  (but  not
including)  April 4, 1996,  and (ii) converting such  monthly rates to corporate
bond equivalent rates. Such calculation
 
                                     S1-22
<PAGE>
does not take into account the interest  rates at which an investor may be  able
to  reinvest funds received by such investor  as distributions on the Class A-14
Certificates and consequently  does not  purport to  reflect the  return on  any
investment  in  the Class  A-14 Certificates  when  such reinvestment  rates are
considered.
 
    The weighted average lives of the  Class A-14 Certificates set forth in  the
preceding   table  were  determined  by  (i)  multiplying  the  amount  of  each
distribution in  reduction  of  the  principal balance  of  the  Series  1992-14
Certificates  by  the  number  of  years  from  April  4,  1996  to  the related
Distribution Date, (ii)  adding the results  and (iii) dividing  the sum by  the
aggregate  distributions in  reduction of  the principal  balance of  the Series
1992-14 Certificates referred to in clause (i).
 
    NOTWITHSTANDING THE  ASSUMED PREPAYMENT  RATES  REFLECTED IN  THE  PRECEDING
TABLE, IT IS HIGHLY UNLIKELY THAT THE MORTGAGE LOANS WILL PREPAY AT ANY CONSTANT
RATE,  THAT THE MORTGAGE LOANS WILL PREPAY AT THE SAME RATE OR THAT THE MORTGAGE
LOANS WILL NOT EXPERIENCE ANY LOSSES. As a result of these factors, the  pre-tax
yield  and weighted average  life of the  Class A-14 Certificates  are likely to
differ from those shown in such table, even if all of the Mortgage Loans  prepay
at the indicated percentages of CPR.
 
                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
    An election has been made to treat the Trust Estate as a REMIC (the "REMIC")
for federal income tax purposes. The Class A-1, Class A-2, Class A-3, Class A-4,
Class  A-5, Class A-6, Class A-7, Class  A-8, Class A-9, Class A-10, Class A-11,
Class A-12, Class A-13 and Class A-14 Certificates, the Class M Certificates and
the Class B-1, Class B-2, Class B-3 and Class B-4 Certificates are designated as
the regular interests in the REMIC  and the Class A-R Certificate is  designated
as  the residual interest in the REMIC. The Proposed REMIC Regulations discussed
in  the   Prospectus   under   the   heading   "Certain   Federal   Income   Tax
Consequences--Federal  Income  Tax  Consequences  for  REMIC  Certificates" were
finalized in substantially the same form on December 23, 1992.
 
    The Class A-14 Certificates are treated as "qualifying real property  loans"
for  mutual savings banks and domestic  building and loan associations, "regular
interests in a  REMIC" for  domestic building  and loan  associations and  "real
estate assets" for real estate investment trusts, to the extent described in the
Prospectus.
 
    The  Class  A-14  Certificates  generally are  treated  as  debt instruments
originated on the date of original  issuance of the Series 1992-14  Certificates
for  federal income tax purposes. Holders of the Class A-14 Certificates will be
required to  report income  thereon in  accordance with  the accrual  method  of
accounting.  The  Proposed  OID  Regulations discussed  in  the  Prospectus were
withdrawn by subsequently  proposed Treasury regulations  on December 22,  1992.
Final  and temporary Treasury regulations regarding original issue discount (the
"OID Regulations")  were  issued on  February  2,  1994. Although  there  is  no
directly applicable authority with respect to the issuance of the Series 1992-14
Certificates,  the Seller  believes that the  Class A-14  Certificates should be
considered to have been issued with  original issue discount in an amount  equal
to  the excess  of all  distributions of principal  and interest  expected to be
received thereon  over  their issue  price  (including accrued  interest).  This
treatment  is consistent  with the  OID Regulations.  Any "negative"  amounts of
original issue discount  on the  Class A-14 Certificates  attributable to  rapid
prepayments  will not be deductible currently,  but may be offset against future
positive accruals of original issue discount, if any. The holder of a Class A-14
Certificate may be entitled to a loss deduction to the extent it becomes certain
that such holder will not  recover a portion of  its basis in such  Certificate,
assuming  no further prepayments.  The Seller makes no  representation as to the
timing or amount of such losses, if any, or how any such losses will be reported
to the holders. See "Certain Federal Income Tax Consequences--Federal Income Tax
Consequences for REMIC Certificates--Taxation of Regular  Certificates--Original
Issue  Discount" in  the Prospectus.  The adjusted issue  price of  a Class A-14
Certificate as of  the date of  purchase by  an investor is  its original  issue
price,  plus original issue discount accrued since the date of original issuance
of the Series 1992-14 Certificates, less distribution made, and losses, if  any,
incurred,  on the Class A-14 Certificates since the date of original issuance of
the Series 1992-14 Certificates. A purchase  price for a Class A-14  Certificate
that  is less than or  greater than the adjusted issue  price of such Class A-14
Certificate will result in market discount or acquisition premium, respectively,
to the beneficial owner thereof, as  discussed in the Prospectus under  "Certain
Federal  Income  Tax  Consequences--Federal Income  Tax  Consequences  for REMIC
Certificates--Taxation of Regular Certificates."

    The Prepayment Assumption  that is  to be used  in determining  the rate  of
accrual  of original  issue discount is  set forth in  the Prospectus Supplement
under   "Federal   Income   Tax   Considerations--Regular   Certificates."    No
representation  is made as to  the actual rate at  which the Mortgage Loans will
prepay.
 
    See "Summary Information--Federal Income Tax Status" and "Federal Income Tax
Considerations" in the  Prospectus Supplement  and "Certain  Federal Income  Tax
Consequences--Federal  Income Tax  Consequences for  REMIC Certificates"  in the
Prospectus.
 
                                  UNDERWRITING
 
    Subject to the terms and conditions of an underwriting agreement and a terms
agreement (together, the  "Underwriting Agreement") among  the Seller, PHMC  and
PaineWebber  Incorporated,  as underwriter  (the "Underwriter")  and, as  to the
terms agreement,  Prudential  Insurance,  the Class  A-14  Certificates  offered
hereby  are being purchased from the Seller by the Underwriter on or about April
4, 1996.  The  Underwriter  is committed  to  purchase  all of  the  Class  A-14
Certificates  offered hereby if  any Class A-14  Certificates are purchased. The
Underwriter has advised  the Seller  that it proposes  to offer  the Class  A-14
Certificates,  from  time  to  time,  for  sale  in  negotiated  transactions or
otherwise at prices determined at the time of sale. Proceeds to the Seller  from
the  sale of the Class A-14 Certificates  are expected to be approximately 1.91%
of the Pool Scheduled Principal Balance as of the Distribution Date in May  1996
without   giving  effect  to  partial   principal  prepayments  or  net  partial
liquidation proceeds received on or after the Determination Date in April  1996,
plus  accrued interest from April 1, 1996  to (but not including) April 4, 1996.
The Underwriter and  any dealers that  participate with the  Underwriter in  the
distribution  of the Class  A-14 Certificates may be  deemed to be underwriters,
and any discounts or commissions received by  them and any profit on the  resale
of Class A-14 Certificates by them may be deemed to be underwriting discounts or
commissions under the Securities Act of 1933, as amended (the "Securities Act").
 
    The  Underwriting Agreement  provides that  the Seller,  PHMC and Prudential
Insurance will indemnify the Underwriter against certain civil liabilities under
the Securities  Act or  contribute  to payments  which  the Underwriter  may  be
required to make in respect thereof.
 
                                SECONDARY MARKET
 
    There  will  not be  any secondary  market for  the Class  A-14 Certificates
offered hereby prior to the offering thereof. The Underwriter intends to act  as
a  market maker in the Class A-14 Certificates, subject to applicable provisions
of federal and state securities laws  and other regulatory requirements, but  is
under  no obligation to do so. There can be no assurance that a secondary market
in the Class A-14 Certificates will develop  or, if such a market does  develop,
that  it  will provide  holders  of Class  A-14  Certificates with  liquidity of
investment  at  any  particular  time  or  for  the  life  of  the  Class   A-14
Certificates.
 
                              ERISA CONSIDERATIONS
 
    As  described in the Prospectus under  "ERISA Considerations," ERISA and the
Code impose certain duties and restrictions  on any person which is an  employee
benefit  plan  within the  meaning of  Section 3(3)  of the  Employee Retirement
Income Security Act of 1974, as amended  ("ERISA"), or Code Section 4975 or  any
person  utilizing the assets of such employee benefit plan (an "ERISA Plan") and
certain persons  who perform  services for  ERISA Plans.  Comparable duties  and
restrictions may exist under federal, state or local laws ("Similar Law"), which
are,  to a material  extent, similar to  the foregoing sections  of ERISA or the
Code, on governmental  plans and  on certain  persons who  perform services  for
governmental plans. For example, unless exempted, investment by an ERISA Plan in
the Class A-14 Certificates may constitute a prohibited transaction under ERISA,
the  Code or  Similar Law.  There are  certain exemptions  issued by  the United
States Department of Labor (the "DOL")  that may be applicable to an  investment
by  an  ERISA Plan  in  the Class  A-14  Certificates, including  the individual
administrative
 
                                     S1-24
<PAGE>
exemption described below and Prohibited Transaction Class Exemption 83-1  ("PTE
83-1"). For a further discussion of PTE 83-1, including the necessary conditions
to  its applicability, and other important factors  to be considered by an ERISA
Plan  contemplating  investing  in  the  Class  A-14  Certificates,  see  "ERISA
Considerations" in the Prospectus.
 
    On  June  25,  1990,  the  DOL  issued  to  the  Underwriter  an  individual
administrative exemption, Prohibited Transaction  Exemption 90-36, 55 Fed.  Reg.
25903  (the "Exemption"),  from certain of  the prohibited  transaction rules of
ERISA with  respect to  the initial  purchase, the  holding and  the  subsequent
resale  by an ERISA  Plan of certificates  in pass-through trusts  that meet the
considerations and requirements of the  Exemption. The Exemption might apply  to
the  acquisition, holding and resale of the  Class A-14 Certificates by an ERISA
Plan, provided that specified conditions are met.
 
    Among the conditions which would have  to be satisfied for the Exemption  to
apply to the acquisition by an ERISA Plan of the Class A-14 Certificates, is the
condition  that the ERISA  Plan investing in  the Class A-14  Certificates be an
"accredited investor"  as defined  in  Rule 501(a)(1)  of  Regulation D  of  the
Securities and Exchange Commission under the Securities Act.
 
    Before  purchasing a  Class A-14 Certificate,  a fiduciary of  an ERISA Plan
should make its own determination as to the availability of the exemptive relief
provided  in  the  Exemption  or  the  availability  of  any  other   prohibited
transaction  exemptions (including PTE 83-1), and  whether the conditions of any
such exemption will be applicable to the Class A-14 Certificates. Any  fiduciary
of an ERISA Plan considering whether to purchase a Class A-14 Certificate should
also  carefully  review with  its own  legal advisors  the applicability  of the
fiduciary duty and prohibited  transaction provisions of ERISA  and the Code  to
such investment. See "ERISA Considerations" in the Prospectus.
 
                                LEGAL INVESTMENT
 
    The  Class A-14  Certificates will constitute  "mortgage related securities"
for purposes  of the  Secondary Mortgage  Market Enhancement  Act of  1984  (the
"Enhancement  Act") so long as  they are rated in one  of the two highest rating
categories  by   at  least   one   nationally  recognized   statistical   rating
organization.  As such,  the Class A-14  Certificates are  legal investments for
certain entities  to  the  extent  provided in  the  Enhancement  Act.  However,
institutions subject to the jurisdiction of the Office of the Comptroller of the
Currency,  the Board  of Governors  of the  Federal Reserve  System, the Federal
Deposit Insurance Corporation,  the Office of  Thrift Supervision, the  National
Credit  Union Administration  or state  banking or  insurance authorities should
review applicable rules, supervisory policies  and guidelines of these  agencies
before  purchasing a Class A-14 Certificate,  as such Certificates may be deemed
to be unsuitable  investments under  one or more  of these  rules, policies  and
guidelines  and certain restrictions may apply  to investments in the Class A-14
Certificates. It should also be noted that certain states recently have enacted,
or have proposed enacting, legislation  limiting to varying extents the  ability
of  certain entities (in  particular insurance companies)  to invest in mortgage
related securities. Investors should  consult with their  own legal advisors  in
determining  whether and to  what extent the  Class A-14 Certificates constitute
legal investments for such investors. See "Legal Investment" in the Prospectus.
 
                                 LEGAL MATTERS
 
    The validity of  the Class A-14  Certificates and certain  tax matters  with
respect  thereto will be passed upon for  the Seller by Cadwalader, Wickersham &
Taft, New York,  New York. Certain  legal matters  will be passed  upon for  the
Underwriter by Brown & Wood, New York, New York.
 
                                USE OF PROCEEDS
 
    The net proceeds to be received from the sale of the Class A-14 Certificates
will  be applied by  the Seller to the  purchase from an  affiliate of the Class
A-14 Certificates.
 
                                     S1-25
<PAGE>
                                    RATINGS
 
    The Class A-14  Certificates have been  rated "AAA" by  Fitch and "AAAr"  by
S&P.  See "Ratings" in the Prospectus Supplement for a further discussion of the
ratings of  the  Certificates. S&P  assigns  the  additional rating  of  "r"  to
highlight classes of securities that S&P believes may experience high volatility
or high variability in expected returns due to non-credit risks.
 
    The  ratings  of Fitch  on  mortgage pass-through  certificates  address the
likelihood of the receipt  by certificateholders of  all distributions to  which
such  certificateholders  are  entitled.  Fitch's  rating  opinions  address the
structural and legal  aspects associated  with the  certificates, including  the
nature  of  the  underlying  mortgage  loans.  Fitch's  ratings  on pass-through
certificates do  not represent  any  assessment of  the  likelihood or  rate  of
principal  prepayments and  consequently any adverse  effect the  timing of such
prepayments could have on an investor's anticipated yield.
 
    S&P's ratings on mortgage  pass-through certificates address the  likelihood
of  receipt by  certificateholders of timely  payments of  interest and ultimate
return of principal. S&P's ratings take into consideration the credit quality of
the mortgage pool including any  credit support providers, structural and  legal
aspects  associated with the  certificates, and the extent  to which the payment
stream of  the mortgage  pool is  adequate to  make payment  required under  the
certificates.  S&P's ratings on  the certificates do  not, however, constitute a
statement regarding the frequency  of prepayments on  the mortgage loans.  S&P's
rating  does not address the possibility that  investors may suffer a lower than
anticipated yield as  a result of  prepayments of the  underlying mortgages.  In
addition,  it should be noted that in some structures a default on a mortgage is
treated as a prepayment and may have the same effect on yield as a prepayment.
 
    The ratings of  Fitch and  S&P do  not address  the possibility  that, as  a
result  of principal  prepayments, Certificateholders  may receive  a lower than
anticipated yield or the possibility that, as a result of prepayments, investors
in  the  Class  A-14  Certificates  may  fail  to  fully  recoup  their  initial
investment.
 
               INCORPORATION OF CERTAIN INFORMATION BY REFERENCE
 
    There  are incorporated herein by reference  all documents and reports filed
or caused to be filed by the Seller with respect to the Trust Estate pursuant to

    The Series 1992-14 Certificates  will evidence in  the aggregate the  entire
beneficial ownership interest in a trust fund (the "Trust Estate") consisting of
a pool of fixed interest rate, conventional, monthly pay, fully amortizing, one-
to four-family, residential first mortgage loans having original terms to stated
maturity of approximately 30 years (the "Mortgage Loans"), together with certain
related  property, sold by The Prudential Home Mortgage Securities Company, Inc.
(the "Seller") and serviced  by The Prudential Home  Mortgage Company, Inc.  (in
its  capacity  as  servicer,  the "Servicer,"  otherwise  "PHMC").  The  Class A
Certificates will  initially evidence  in the  aggregate an  approximate  91.50%
undivided  interest in the principal balance of  the Mortgage Loans. The Class M
Certificates will  initially  evidence in  the  aggregate an  approximate  3.25%
undivided interest in the principal balance of the Mortgage Loans. The remaining
approximate  5.25% undivided interest  in the principal  balance of the Mortgage
Loans will be evidenced by the Class B Certificates.
 
    Distributions in respect of interest  will be made on  the 25th day of  each
month  or the  next succeeding  business day,  commencing in  June 1992,  to the
holders of Offered  Certificates, other  than the Accrual  Certificates, to  the
extent  described herein. Distributions in respect of interest to the holders of
the Accrual Certificates will not commence until the Accretion Termination Date.
Prior to such time, interest otherwise available for distribution to the Accrual
Certificates will be added to the  principal balance thereof. The rights of  the
holders of the Class M Certificates to receive distributions of interest will be
subordinated to the rights of the holders of the Class A Certificates to receive
distributions  of  interest and  principal as  described  herein. The  amount of
interest accrued  on any  Subclass  or Class  of  Offered Certificates  will  be
reduced by the amount of (i) any Non-Supported Interest Shortfall and (ii) other
losses   allocable  to  such  Subclass  or   Class  as  described  herein  under
"Description of the Certificates--Interest."  Distributions in reduction of  the
principal  balance of  the Class  A Certificates  will be  made monthly  on each
Distribution Date  in  an  aggregate  amount equal  to  the  Class  A  Principal
Distribution  Amount. Distributions in reduction of the principal balance of the
Class M  Certificates will  be made  monthly  on each  Distribution Date  in  an
aggregate  amount equal to  the Class M Principal  Distribution Amount after the
Class A Certificates have received the Class A Distribution Amount and the Class
M Certificates have received their amount  of interest due with respect to  such
Distribution  Date. Distributions in  reduction of the  principal balance of the
Class A  Certificates on  any  Distribution Date  will  be allocated  among  the
Subclasses  of  Class  A  Certificates  in  the  manner  described  herein under
"Description   of   the   Certificates--Principal   (Including    Prepayments)."
Distributions to each Subclass or Class of Offered Certificates will be made pro
rata among Certificateholders of such Subclass or Class.
 
    THE  YIELD  TO MATURITY  OF THE  OFFERED CERTIFICATES  WILL BE  SENSITIVE IN
VARYING DEGREES  TO  THE  RATE  AND  TIMING  OF  PRINCIPAL  PAYMENTS  (INCLUDING
PREPAYMENTS)  ON THE MORTGAGE  LOANS, WHICH MAY  BE PREPAID AT  ANY TIME WITHOUT
PENALTY. INVESTORS IN  THE OFFERED CERTIFICATES  SHOULD CONSIDER THE  ASSOCIATED
RISKS,  INCLUDING, IN THE CASE OF  OFFERED CERTIFICATES PURCHASED AT A DISCOUNT,
THE RISK THAT A SLOWER THAN ANTICIPATED RATE OF PAYMENTS IN RESPECT OF PRINCIPAL
(INCLUDING PREPAYMENTS) ON THE  MORTGAGE LOANS COULD RESULT  IN AN ACTUAL  YIELD
THAT  IS  LOWER  THAN  ANTICIPATED  AND, IN  THE  CASE  OF  OFFERED CERTIFICATES
PURCHASED AT  A PREMIUM,  THAT A  FASTER THAN  ANTICIPATED RATE  OF PAYMENTS  IN
RESPECT  OF PRINCIPAL (INCLUDING PREPAYMENTS) ON THE MORTGAGE LOANS COULD RESULT
IN AN  ACTUAL YIELD  THAT IS  LOWER THAN  ANTICIPATED. SEE  "DESCRIPTION OF  THE
CERTIFICATES--INTEREST"  AND  "--PRINCIPAL (INCLUDING  PREPAYMENTS)"  HEREIN AND
"PREPAYMENT AND YIELD CONSIDERATIONS" HEREIN AND IN THE PROSPECTUS.
 
    THE YIELD TO MATURITY OF THE CLASS M CERTIFICATES WILL BE MORE SENSITIVE  TO
LOSSES  DUE TO LIQUIDATIONS OF THE MORTGAGE  LOANS (AND THE TIMING THEREOF) THAN
THE CLASS A CERTIFICATES, TO THE EXTENT  THAT THE CLASS B PRINCIPAL BALANCE  HAS
BEEN REDUCED TO ZERO. SEE "DESCRIPTION OF THE CERTIFICATES--PRINCIPAL (INCLUDING
PREPAYMENTS)" AND "--SUBORDINATION OF CLASS M AND CLASS B CERTIFICATES" HEREIN.
 
    The Offered Certificates (other than the Class A-R and Class M Certificates)
will  be  issued only  in book-entry  form  (the "Book-Entry  Certificates") and
purchasers thereof  will  not be  entitled  to receive  definitive  certificates
except   in  the  limited   circumstances  set  forth   herein.  The  Book-Entry
Certificates will be registered  in the name  of Cede & Co.,  as nominee of  The
Depository  Trust Company, which will be  the "holder" or "Certificateholder" of
such Certificates,  as such  terms  are used  herein.  See "Description  of  the
Certificates" herein.
 
    There  is currently  no secondary  market for  the Offered  Certificates and
there can be no assurance  that a secondary market will  develop or, if it  does
develop, that it will provide Certificateholders with liquidity of investment at
any particular time or for the life of the Offered Certificates. The Underwriter
intends  to  act as  a  market maker  in  the Offered  Certificates,  subject to
applicable provisions of federal and state securities laws and other  regulatory
requirements,  but is under no obligation to do so. THE CLASS M CERTIFICATES MAY
NOT BE PURCHASED BY OR TRANSFERRED TO AN ERISA PLAN EXCEPT UPON THE DELIVERY  OF
AN OPINION OF COUNSEL AS PROVIDED HEREIN. IN ADDITION, THE CLASS A-R CERTIFICATE
MAY  NOT BE PURCHASED BY OR TRANSFERRED  TO (I) A "DISQUALIFIED ORGANIZATION" OR
"BOOK-ENTRY NOMINEE," (II) EXCEPT  UNDER CERTAIN LIMITED CIRCUMSTANCES,  PERSONS
WHO ARE NOT "U.S. PERSONS," (III) AN ERISA PLAN OR (IV) ANY PERSON OR ENTITY WHO
THE  TRANSFEROR  HAS  REASON TO  BELIEVE  INTENDS  TO IMPEDE  THE  ASSESSMENT OR
COLLECTION OF ANY FEDERAL, STATE OR LOCAL TAXES LEGALLY REQUIRED TO BE PAID WITH
RESPECT  THERETO.   See  "ERISA   Considerations"   and  "Description   of   the
Certificates--Restrictions   on  Transfer   of  the   Class  A-R   and  Class  M
Certificates" herein,  and  "Certain Federal  Income  Tax  Consequences--Federal
Income   Tax   Consequences   for  REMIC   Certificates--Taxation   of  Residual
Certificates--Tax-Related Restrictions on Transfer of Residual Certificates"  in
the Prospectus.
 
    An election will be made to treat the Trust Estate as a real estate mortgage
investment  conduit (the "REMIC") for federal  income tax purposes. As described
more fully herein and in  the Prospectus, the Class  A-1, Class A-2, Class  A-3,
Class  A-4, Class A-5, Class  A-6, Class A-7, Class  A-8, Class A-9, Class A-10,
Class A-11, Class A-12, Class A-13, Class A-14 and Class M Certificates and each
subclass of the Class B Certificates will constitute "regular interests" in  the
REMIC  and the Class A-R Certificate  will constitute the "residual interest" in
the  REMIC.   PROSPECTIVE   INVESTORS  ARE   CAUTIONED   THAT  THE   CLASS   A-R
CERTIFICATEHOLDER'S REMIC TAXABLE INCOME AND SUCH HOLDER'S TAX LIABILITY THEREON
WILL  EXCEED CASH DISTRIBUTIONS TO SUCH  HOLDER DURING CERTAIN PERIODS, IN WHICH
EVENT THE HOLDER THEREOF  MUST HAVE SUFFICIENT ALTERNATIVE  SOURCES OF FUNDS  TO
PAY SUCH TAX LIABILITY. See "Summary Information--Federal Income Tax Status" and
"Federal  Income  Tax Considerations"  herein  and "Certain  Federal  Income Tax
Consequences--Federal Income  Tax Consequences  for REMIC  Certificates" in  the
Prospectus.
 
    The  Class A Certificates (other than the Class A-14 Certificates) represent
fourteen Subclasses of a Class and the Class M Certificates represent a Class of
a separate Series of  Certificates being offered by  the Seller pursuant to  the
Prospectus  dated  April 8,  1992 accompanying  this Prospectus  Supplement. Any
prospective investor  should not  purchase  any Offered  Certificates  described
herein  unless  it  shall  have  received  the  Prospectus  and  this Prospectus
Supplement. The  Prospectus  shall  not  be  considered  complete  without  this
Prospectus  Supplement. The Prospectus  contains important information regarding
this offering which is not contained herein, and prospective investors are urged
to read, in full, the Prospectus and this Prospectus Supplement.
                           --------------------------
    UNTIL AUGUST  10, 1992  ALL DEALERS  EFFECTING TRANSACTIONS  IN THE  OFFERED
CERTIFICATES, WHETHER OR NOT PARTICIPATING IN THIS DISTRIBUTION, MAY BE REQUIRED
TO  DELIVER A PROSPECTUS SUPPLEMENT  AND PROSPECTUS. THIS IS  IN ADDITION TO THE
OBLIGATION OF DEALERS  TO DELIVER  A PROSPECTUS SUPPLEMENT  AND PROSPECTUS  WHEN

Title of Securities...  Mortgage  Pass-Through Certificates, Series 1992-14 (the

Seller................  The Prudential  Home Mortgage  Securities Company,  Inc.
                        (the "Seller"). See "The Seller" in the Prospectus.
Servicer..............  The  Prudential  Home  Mortgage  Company,  Inc.  (in its
                        capacity  as   servicer,  the   "Servicer;"   otherwise,
                        "PHMC").  See  "Servicing  of  the  Mortgage  Loans" and
                        "PHMC--General" in the Prospectus.

Rating of
  Certificates........  It is  a  condition  to  the issuance  of  the  Class  A
                        Certificates  offered by this  Prospectus Supplement and
                        the Prospectus that they shall have been rated "AAA"  by
                        Standard   &  Poor's   Corporation  ("S&P")   and  Fitch
                        Investors Service, Inc. ("Fitch"). It is a condition  to
                        the issuance of the Class M Certificates that they shall
                        have  been rated "AA"  by S&P and  Fitch. The ratings by
                        S&P and Fitch  are not recommendations  to buy, sell  or
                        hold such Certificates and may be subject to revision or
                        withdrawal  at any time by  the assigning rating agency.
                        The ratings do  not address the  possibility that, as  a
                        result   of  principal  prepayments,   holders  of  such
                        Certificates may receive a lower than anticipated yield.
                        See   "--Effects    of   Prepayments    on    Investment
                        Expectations"  below  and "Ratings"  in  this Prospectus
                        Supplement.
Description of
  Certificates........  The Series 1992-14 Certificates will consist of Class  A
                        Certificates,   Class   M  Certificates   and   Class  B
                        Certificates. The Class A Certificates represent a  type
                        of  interest referred  to in  the Prospectus  as "Senior
                        Certificates;" and the Class M and Class B Certificates,
                        a  type  of  interest   referred  to  as   "Subordinated
                        Certificates."  As these designations suggest, the Class
                        A Certificates  are  entitled  to  a  certain  priority,
                        relative  to the  Class M  and Class  B Certificates, in
                        right of distributions on the mortgage loans  underlying
                        the  Series 1992-14 Certificates (the "Mortgage Loans").
                        As between  the Class  M Certificates  and the  Class  B
                        Certificates, the Class M Certificates are entitled to a
                        certain  priority  in  right  of  distributions  on  the
                        Mortgage Loans.  See "--Distributions  of Principal  and
                        Interest" below.
                        Initially, the Class A Certificates will evidence in the
                        aggregate    an   approximate    91.50%   (approximately
                        $435,864,000)  undivided   interest   in   the   initial
                        aggregate  principal balance of  the Mortgage Loans; the
                        Class M Certificates will  evidence in the aggregate  an
                        approximate  3.25% (approximately $15,481,000) undivided
                        interest in the initial  aggregate principal balance  of
                        the  Mortgage Loans;  and the Class  B Certificates will
                        evidence  in   the   aggregate  an   approximate   5.25%

                        the  Mortgage Loans represented by  the Class A, Class M

                        because of  the disproportionate  allocation of  certain
                        unscheduled   principal   payments   to   the   Class  A
                        Certificates and the allocation of certain losses  first
                        to   the  Class  B   Certificates  until  the  aggregate
                        principal balance thereof has  been reduced to zero  and
                        then  to the  Class M  Certificates until  the aggregate
                        principal balance  thereof  has been  reduced  to  zero,
                        prior  to the allocation  of such losses  to the Class A
                        Certificates, as discussed in "--Distributions of  Prin-
                        cipal and of Interest" and "--Credit Enhancement" below.
                        The   Class  A  Certificates  will  consist  of  fifteen
                        subclasses, designated  as  the Class  A-1,  Class  A-2,
                        Class  A-3, Class A-4, Class  A-5, Class A-6, Class A-7,
                        Class A-8,  Class A-9,  Class  A-10, Class  A-11,  Class
                        A-12, Class A-13, Class A-14 and Class A-R Certificates.
                        The  Class A-10 Certificates are also referred to herein
                        as  "Accrual  Certificates"  because  the  interest  due
                        holders  of such subclass will  not be paid currently on
                        any Distribution Date but, instead, will be added to the
                        principal balance of such  subclass until the  Accretion
                        Termination  Date, which  is described on  page S-9. The
                        Class A-11, Class A-12 and Class A-13 Certificates  will
                        receive,   prior  to  the  Accretion  Termination  Date,
                        principal payments equal to the accrued interest on  the
                        Accrual   Certificates,  and  are   referred  to  herein
                        collectively as the  "Accretion Directed  Certificates."
                        The  Class  M  Certificates  will  not  be  divided into
                        subclasses. The  Class B  Certificates will  consist  of
                        four subclasses, designated as the Class B-1, Class B-2,
                        Class B-3 and Class B-4 Certificates.
                        The  Class  A Certificates  (other  than the  Class A-14
                        Certificates) and Class M Certificates are being offered
                        for  sale  by   this  Prospectus   Supplement  and   the
                        Prospectus  and  are  referred  to  in  this  Prospectus
                        Supplement as the "Offered Certificates." References  to
                        the  "Subordinated Certificates" are to  the Class M and
                        Class B Certificates.  The Class  A-14 Certificates  and
                        one  or more of  the subclasses of  Class B Certificates
                        may be retained or sold by the Seller.
                        The Offered Certificates have the approximate  aggregate
                        initial  principal balances  set forth  on the  cover of
                        this Prospectus Supplement.  Any difference between  the
                        aggregate  principal balance of the  Class A and Class M
                        Certificates as of  the date of  issuance of the  Series
                        1992-14   Certificates   and  the   approximate  initial
                        aggregate principal balance of the  Class A and Class  M
                        Certificates   as  of   the  date   of  this  Prospectus
                        Supplement  will  not,  with  respect  to  the  Class  A
                        Certificates  (other than the  Class A-14 Certificates),
                        exceed 5% of the initial aggregate principal balance  of
                        such  Class A Certificates  stated on the  cover of this
                        Prospectus Supplement and, with  respect to the Class  M
                        Certificates,  will  depend on  the  final subordination
                        levels  for   the  Series   1992-14  Certificates.   Any
                        difference allocated to the Class A Certificates will be
                        allocated  among the subclasses  of Class A Certificates
                        other than the Class A-14 and Class A-R Certificates.

Forms of Certificates;
  Denominations.......  BOOK-ENTRY FORM.  The  Offered Certificates (other  than
                        the  Class A-R and Class  M Certificates) will be issued
                        in  book-entry  form,  through  the  facilities  of  The
                        Depository Trust Company ("DTC"). These Certificates are
                        referred to, collectively, in this Prospectus Supplement
                        as  the  "Book-Entry  Certificates."  An  investor  in a
                        subclass of Book-Entry Certificates  will not receive  a
                        physical certificate representing its ownership interest
                        in    such   Book-Entry   Certificates,   except   under
                        extraordinary  circumstances,  which  are  discussed  in
                        "Description of the Certificates--Definitive
                        Certificates"  in  this Prospectus  Supplement. Instead,
                        DTC will effect payments and  transfers by means of  its
                        electronic   recordkeeping   services,   acting  through
                        certain participating organizations. This may result  in
                        certain   delays  in  receipt  of  distributions  by  an
                        investor and  may  restrict  an  investor's  ability  to
                        pledge  its securities.  The rights of  investors in the
                        Book-Entry Certificates may generally only be  exercised
                        through  DTC  and its  participating  organizations. See
                        "Description of the Certificates--Book-Entry
                        Registration" in this Prospectus Supplement.
                        The Book-Entry Certificates,  other than  the Class  A-8
                        Certificates, will be issued in minimum denominations of
                        $100,000   initial  principal  balance.  The  Class  A-8
                        Certificates will be issued in minimum denominations  of
                        $1,000  initial principal balance. Any amounts in excess
                        of $100,000,  or $1,000  in the  case of  the Class  A-8
                        Certificates,  will be  in integral  multiples of $1,000
                        initial principal balance.
                        CERTIFICATED  FORM.     The  Class  A-R   and  Class   M
                        Certificates   will  be  offered  in  fully  registered,
                        certificated form. Accordingly, an investor in any  such
                        subclass  or class will be issued a physical certificate
                        representing its ownership interest.
                        The Class  M  Certificates  will be  issued  in  minimum
                        denominations of $100,000 initial principal balance. Any
                        amounts  in  excess  of  $100,000  will  be  in integral
                        multiples of $1,000 initial principal balance. The Class
                        A-R Certificate will be  issued in a single  certificate
                        with  a  denomination  of  $1,090,000  initial principal
                        balance. See "Description of the  Certificates--General"

Mortgage Loans........  MORTGAGE  LOAN DATA.  The  Mortgage Loans, which are the
                        source of distributions to holders of the Series 1992-14
                        Certificates, are expected  to consist of  conventional,
                        fixed interest rate, monthly pay, fully amortizing, one-
                        to four-family, residential first mortgage loans, having
                        original  terms to  stated maturity  of approximately 30
                        years. The  Mortgage  Loans  are expected  to  have  the
                        further  specifications set forth in the table appearing
                        below and under the heading "Description of the Mortgage

                        CHANGES  TO POOL.  A number of Mortgage Loans may be re-
                        moved from the pool, or  a substitution may be made  for
                        certain  Mortgage Loans,  in advance of  the issuance of
                        the Series 1992-14  Certificates (which  is expected  to
                        occur  on or  about May  27, 1992).  This may  result in
                        changes in certain of the pool characteristics set forth
                        in the  table above  and  elsewhere in  this  Prospectus
                        Supplement.  See "Description of  the Mortgage Loans" in
                        this Prospectus Supplement.
                        Subsequent  to  the  issuance  of  the  Series   1992-14
                        Certificates, certain Mortgage Loans may be removed from
                        the   pool   through   repurchase   or,   under  certain
                        circumstances,  substitution  by  the  Seller,  if   the
                        Mortgage   Loans  are   discovered  to   have  defective
                        documentation or if they otherwise do not conform to the
                        standards established  by the  Seller's  representations
                        and   warranties  concerning  the  Mortgage  Loans.  See
                        "Description of the Mortgage Loans--Mandatory Repurchase
                        or Substitution of  Mortgage Loans"  in this  Prospectus
                        Supplement.  The  Seller may  also  repurchase defaulted
                        Mortgage  Loans.  See   "Description  of  the   Mortgage
                        Loans--Optional  Repurchase of Defaulted Mortgage Loans"

                        purchase all outstanding Mortgage Loans in the pool  and

Distributions of
  Principal and
  Interest............  DISTRIBUTIONS  IN GENERAL.  Distributions on  the Series
                        1992-14 Certificates will  be made  on the  25th day  of
                        each month or, if such day is not a business day, on the
                        succeeding  business day (each such  date is referred to
                        in this Prospectus Supplement as a "Distribution Date"),
                        to holders of  record at  the close of  business on  the
                        last business day of the preceding month. In the case of
                        the  Book-Entry Certificates, the  holder of record will
                        be DTC.
                        On  any  Distribution  Date,  holders  of  the  Class  A
                        Certificates will be entitled to receive all amounts due
                        them before any distributions are made to holders of the
                        Class  M and  Class B Certificates  on that Distribution
                        Date. The amount that is available to be distributed  on
                        any  Distribution Date  will be  allocated first  to pay
                        interest due  holders of  the Class  A Certificates  and
                        then,  if the amount  available for distribution exceeds
                        the amount  of  interest  due holders  of  the  Class  A
                        Certificates,   to  reduce   the  outstanding  principal
                        balance of  the  Class  A  Certificates.  Prior  to  the
                        Accretion  Termination  Date,  interest  accrued  on the
                        Accrual  Certificates   will  be   distributed  to   the
                        Accretion   Directed  Certificates  as  a  reduction  of
                        principal. The likelihood that a holder of a  particular
                        subclass  of  the  Class  A  Certificates  will  receive
                        principal distributions  on any  Distribution Date  will
                        depend  on  the  priority  in  which  such  subclass  is
                        entitled to principal distributions, as set forth  under
                        the  heading "Description of the Certificates--Principal
                        (Including  Prepayments)--Allocation  of  Amount  to  be
                        Distributed to the Class A and Class M Certificates," in
                        this Prospectus Supplement.
                        After  all amounts due  on the Class  A Certificates for
                        any  Distribution  Date  have  been  paid,  the   amount
                        remaining  will  be allocated  to  (i) pay  interest due
                        holders of  the Class  M Certificates,  (ii) reduce  the
                        outstanding   principal   balance   of   the   Class   M
                        Certificates, (iii) pay interest  due to the holders  of
                        the Class B Certificates and (iv) reduce the outstanding
                        principal  balance  of  the  Class  B  Certificates. The
                        amount available  for distribution  on any  Distribution
                        Date  is primarily a function  of the amount remitted by
                        mortgagors of  the Mortgage  Loans in  payment of  their
                        scheduled  installments  of principal  and  interest, as
                        well as the amount of prepayments by the mortgagors  and
                        proceeds from liquidations of defaulted Mortgage Loans.
                        If  any  mortgagor  is  delinquent  in  the  payment  of
                        principal or interest on a  Mortgage Loan in any  month,
                        the  Servicer will advance such payment, if the Servicer

                        for such subclass or class multiplied by the outstanding
                        principal  balance of such  subclass or class  as of the
                        related Distribution  Date.  The pass-through  rate  for
                        each  such subclass or class is the percentage set forth
                        on the cover of this Prospectus Supplement.
                        The amount of interest to which the holder of the  Class
                        A-R  Certificate  is entitled  each month  is calculated
                        based on a "notional amount,"  which is an amount  other
                        than  the actual  outstanding principal  balance of such
                        subclass. The method of determining the notional  amount
                        of   the  Class  A-R   Certificate  is  described  under
                        "Description  of  the  Certificates--Interest"  in  this
                        Prospectus Supplement. Interest will accrue on the Class
                        A-R  Certificate each  month in  an amount  equal to the
                        product of (i)  1/12th of  8.00% and  (ii) the  notional
                        amount of the Class A-R Certificate.
                        Holders   of   each   subclass  or   class   of  Offered
                        Certificates, other than the Accrual Certificates,  will
                        be entitled to receive distributions of interest on each
                        Distribution  Date. Holders of  the Accrual Certificates
                        will  not  be  entitled  to  receive  distributions   of
                        interest  until the "Accretion  Termination Date," which
                        is defined as the earlier  of (i) the Distribution  Date
                        on  which  the  principal  balance  of  the  Class  A-13
                        Certificates has been reduced to zero and (ii) the  date
                        on  which  the  principal  balance  of  the Subordinated
                        Certificates has been reduced to zero. See  "Description

                        Supplement. Before that time, the amount of interest  to
                        which  the  holders  of  the  Accrual  Certificates  are
                        entitled will  not be  distributed  as interest  to  the
                        holders of the Accrual Certificates but will be added to
                        the  principal balance of  the Accrual Certificates. The
                        amount  of  interest  which  has  accrued  but  is   not
                        currently distributable on the Accrual Certificates will
                        be distributed to the Accretion Directed Certificates as
                        a  reduction  of  principal.  See  "Description  of  the

                        interest  for  the month  of  payment may  not  be paid,
                        resulting in  interest shortfalls.  Any such  shortfalls
                        that  result from the timing of principal prepayments IN
                        FULL will  be paid  from aggregate  servicing fees  that
                        would  otherwise  be  payable  to  the  Servicer  on any
                        Distribution Date, but only  to the extent of  servicing
                        fees payable with respect to that Distribution Date. Any
                        such  shortfalls that result from  the timing of PARTIAL
                        principal prepayments will reduce the amount of interest

                        interest resulting from  principal prepayments in  full,
                        to  the extent they exceed the aggregate servicing fees,
                        and shortfalls resulting  from partial prepayments  will

                        Certificates are entitled each month will be composed of
                        a  percentage of the scheduled  payments of principal on
                        the  Mortgage  Loans   and  a   percentage  of   certain
                        unscheduled payments of principal on the Mortgage Loans.
                        The  percentage of scheduled payments  will be equal, on
                        each Distribution Date, to the fraction that  represents
                        the  ratio of the  then-outstanding principal balance of

                        percentage of certain unscheduled payments will be equal
                        to  the percentage  described in  the preceding sentence

                        receive distributions will be subordinated to the rights
                        of the holders  of the Class  A Certificates to  receive
                        distributions,  to  the  extent  described  herein.  The
                        rights of the  holders of  the Class  B Certificates  to
                        receive distributions will be subordinated to the rights
                        of  the holders of the Class  A and Class M Certificates
                        to receive distributions to the extent described herein.
                        This  subordination   provides  a   certain  amount   of
                        protection  to the  holders of the  Class A Certificates
                        (to the extent of the  subordination of the Class M  and
                        Class  B Certificates) and the  Class M Certificates (to
                        the  extent  of  the   subordination  of  the  Class   B

                        payments  of interest  and principal  and against losses
                        associated with  the liquidation  of defaulted  Mortgage

                        mortgagor. The protection  afforded the  holders of  the
                        Class A Certificates by means of this subordination will
                        be  effected in two ways:  (i) by the preferential right
                        of the holders of the  Class A Certificates to  receive,
                        prior to any distribution being made on any Distribution
                        Date in respect of the Class M and Class B Certificates,
                        the amounts of interest and principal due the holders of
                        the Class A Certificates on such date and, if necessary,
                        by   the  right  of  such   holders  to  receive  future
                        distributions on the Mortgage Loans that would otherwise
                        have been allocated to  the holders of  the Class M  and
                        Class  B Certificates; and (ii) by the allocation to the
                        holders of  the  Class M  and  Class B  Certificates  of
                        certain  amounts and types of  losses resulting from the
                        liquidation of the Mortgage  Loans or the bankruptcy  of
                        the mortgagor.
                        The  protection  afforded  the holders  of  the  Class M
                        Certificates by means of this subordination will also be
                        effected in two ways:

                        Class   M   Certificates  to   receive,  prior   to  any
                        distribution being  made  on any  Distribution  Date  in

                        the  Mortgage  Loans  that  would  otherwise  have  been
                        allocated  to the  holders of the  Class B Certificates;

                        Certificates of  certain  amounts and  types  of  losses
                        resulting  from the liquidation of the Mortgage Loans or
                        the bankruptcy of the mortgagor.
                        In  order  to  increase  the  period  during  which  the
                        principal   balance  of  the  Subordinated  Certificates
                        remains  available  to   absorb  losses  on   liquidated
                        Mortgage Loans, a disproportionate amount of prepayments
                        and  certain unscheduled recoveries  with respect to the
                        Mortgage  Loans  will  be  allocated  to  the  Class   A
                        Certificates.   This  allocation   has  the   effect  of
                        accelerating   the   amortization   of   the   Class   A
                        Certificates  while, in the absence of losses in respect
                        of liquidations of  Mortgage Loans  or losses  resulting
                        from  the  bankruptcy of  the mortgagor,  increasing the

                        EXTENT OF LOSS  COVERAGE.  Realized  losses on  Mortgage
                        Loans,  other than  losses that are  (i) attributable to
                        "special hazards" not insured  against under a  standard
                        hazard  insurance  policy,  (ii)  incurred  on defaulted
                        Mortgage Loans  as  to  which there  was  fraud  in  the
                        origination of such Mortgage Loans or (iii) attributable
                        to  certain actions which  may be taken  by a bankruptcy
                        court in connection  with a Mortgage  Loan, including  a
                        reduction by a bankruptcy court of the principal balance
                        of  or  the  interest  rate on  a  Mortgage  Loan  or an
                        extension of its maturity, will not be allocated to  the
                        Class  A  Certificates  until  the  date  on  which  the
                        aggregate principal balance of the  Class M and Class  B
                        Certificates   (which  aggregate   balance  is  expected
                        initially to  be  approximately  $40,490,867)  has  been
                        reduced to zero and will not be allocated to the Class M
                        Certificates  until  the  date  on  which  the aggregate
                        principal balance  of the  Class B  Certificates  (which

                        $25,009,867) has been reduced to zero. Such losses  will
                        be  allocated first among the  subclasses of the Class B
                        Certificates, in reverse numerical  order, to the  Class

                        and Class  M  Certificates  to  absorb  losses  will  be
                        affected   by  the  prior  reduction  of  the  principal
                        balances of  the  Class  M  and  Class  B  Certificates.
                        Reduction  of  the  principal  balance  of  the  Class M

                        Certificates  will result from  (i) the prior allocation
                        of losses on  liquidation of  defaulted Mortgage  Loans,
                        including losses due to special hazards and fraud losses
                        up  to  the  limit  referred to  below,  (ii)  the prior
                        allocation of bankruptcy losses up to the limit referred

                        distributions  by the holders of such class or subclass.

                        bankruptcy that will be  absorbed solely by the  holders
                        of  the  Class B  Certificates  and then  solely  by the
                        holders  of   the   Class   M   Certificates   will   be
                        approximately  1.28%, 2.00% and  0.11%, respectively, of
                        the aggregate principal balance of the Mortgage Loans as
                        of   the   Cut-Off   Date   (approximately   $6,097,342,
                        $9,527,097  and  $504,237, respectively).  These amounts
                        may be reduced  as described under  "Description of  the
                        Certificates--Subordination  of the Class  M and Class B
                        Certificates--Allocation of Losses"  in this  Prospectus
                        Supplement.  If losses due to  special hazards, fraud or
                        bankruptcy exceed  any  of  such amounts  prior  to  the
                        principal   balances  of   the  Class  M   and  Class  B
                        Certificates being reduced to zero, such losses will  be
                        shared   pro  rata   by  the   subclasses  of   Class  A
                        Certificates and the Class  M and Class B  Certificates.
                        After  the principal balances of the Class M and Class B
                        Certificates have been reduced to zero, such losses will
                        be  shared  pro  rata  by  the  subclasses  of  Class  A
                        Certificates  based on  their principal  balances, or in
                        the case  of  the Accrual  Certificates,  their  initial
                        principal balance, if lower.
                        THE  YIELD TO MATURITY ON  THE CLASS M CERTIFICATES WILL
                        BE MORE SENSITIVE TO LOSSES  DUE TO LIQUIDATIONS OF  THE
                        MORTGAGE LOANS (AND THE TIMING THEREOF) THAN THE CLASS A
                        CERTIFICATES,  TO THE EXTENT  THAT THE PRINCIPAL BALANCE
                        OF THE CLASS B CERTIFICATES HAS BEEN REDUCED TO ZERO.

Effects of Prepayments
  on Investment
  Expectations........  The actual  rate  of  prepayment  of  principal  on  the
                        Mortgage  Loans  can  not be  predicted.  The investment
                        performance  of  the   Offered  Certificates  may   vary
                        materially    and   adversely    from   the   investment
                        expectations of  investors  due to  prepayments  on  the
                        Mortgage  Loans being higher  or lower than anticipated.
                        It is possible that the actual yield to the holder of an
                        Offered Certificate  may  not  be  equal  to  the  yield
                        anticipated  at the time of  purchase of the Certificate
                        or, notwithstanding that  the actual yield  is equal  to
                        the  yield  anticipated  at that  time,  that  the total
                        return on  investment expected  by the  investor or  the
                        expected  weighted average  life of  the Certificate may
                        not be realized. These effects are summarized below.  IN
                        DECIDING  WHETHER TO PURCHASE  ANY OFFERED CERTIFICATES,
                        AN INVESTOR SHOULD  MAKE AN INDEPENDENT  DECISION AS  TO
                        THE APPROPRIATE PREPAYMENT ASSUMPTIONS TO BE USED.
                        YIELD.   If an investor purchases an Offered Certificate
                        at an amount equal to its unpaid principal balance (that
                        is, at  "par"), the  effective  yield to  that  investor
                        (assuming  that all  interest shortfalls  are covered by
                        servicing fees  otherwise payable  to the  Servicer  and
                        assuming  the  full return  of the  purchaser's invested
                        principal) will  approximate  the pass-through  rate  on
                        that  Certificate. If an investor pays less or more than
                        the unpaid principal  balance of  the Certificate  (that
                        is,  buys the Certificate at  a "discount" or "premium,"
                        respectively), then, based on the assumptions set  forth
                        in  the preceding  sentence, the effective  yield to the
                        investor will be higher or lower, respectively, than the
                        stated

                        interest rate on the Certificate, because such  discount
                        or  premium  will  be  amortized over  the  life  of the
                        Certificate.  Any  deviation  in  the  actual  rate   of
                        prepayments  on the Mortgage Loans from the rate assumed
                        by the  investor will  affect the  period of  time  over
                        which,  or the  rate at  which, the  discount or premium
                        will be  amortized and,  consequently, will  change  the
                        investor's   actual  yield  from  that  anticipated.  AN
                        INVESTOR THAT PURCHASES  ANY OFFERED  CERTIFICATES AT  A
                        DISCOUNT  SHOULD  CAREFULLY  CONSIDER  THE  RISK  THAT A
                        SLOWER THAN ANTICIPATED  RATE OF  PRINCIPAL PAYMENTS  ON
                        THE  MORTGAGE LOANS WILL RESULT  IN AN ACTUAL YIELD THAT
                        IS LOWER  THAN  THE  EXPECTED YIELD.  AN  INVESTOR  THAT
                        PURCHASES  ANY OFFERED CERTIFICATES  AT A PREMIUM SHOULD
                        CONSIDER THE RISK THAT A FASTER THAN ANTICIPATED RATE OF
                        PRINCIPAL PAYMENTS ON THE MORTGAGE LOANS WILL RESULT  IN
                        AN ACTUAL YIELD THAT IS LOWER THAN THE EXPECTED YIELD.
                        REINVESTMENT RISK.  As stated above, if a Certificate is
                        purchased  at an  amount equal  to its  unpaid principal
                        balance, fluctuations in  the rate  of distributions  of
                        principal   will  generally  not  affect  the  yield  to
                        maturity of that Certificate. However, the total  return
                        on any purchaser's investment, including an investor who
                        purchases  at par,  will be  reduced to  the extent that
                        principal distributions received on its Certificate  can
                        not  be  reinvested  at a  rate  as high  as  the stated
                        interest rate  of  the  Certificate.  Investors  in  the
                        Offered Certificates should consider the risk that rapid
                        rates  of prepayments on the Mortgage Loans may coincide
                        with periods of  low prevailing  market interest  rates.
                        During  periods of low prevailing market interest rates,
                        mortgagors  may  be  expected  to  prepay  or  refinance
                        Mortgage  Loans that carry  interest rates significantly
                        higher than  then-current  interest rates  for  mortgage
                        loans.  Consequently, the amount  of principal distribu-
                        tions available to an investor for reinvestment at  such
                        low  prevailing interest rates  may be relatively large.
                        Conversely, slow rates  of prepayments  on the  Mortgage
                        Loans  may  coincide  with  periods  of  high prevailing
                        market interest rates. During  such periods, it is  less
                        likely that mortgagors will elect to prepay or refinance
                        Mortgage  Loans and, therefore,  the amount of principal
                        distributions available to an investor for  reinvestment
                        at such high prevailing interest rates may be relatively
                        small.
                        WEIGHTED AVERAGE LIFE VOLATILITY.  One indication of the
                        impact of varying prepayment speeds on a security is the
                        change  in  its  weighted  average  life.  The "weighted
                        average life" of an  Offered Certificate is the  average
                        amount  of  time that  will elapse  between the  date of
                        issuance  of  the  Certificate  until  each  dollar   in
                        reduction of the principal balance of the Certificate is
                        distributed to the investor. Low rates of prepayment may
                        result  in extension of  the weighted average  life of a
                        Certificate; high  rates,  in  the  shortening  of  such
                        weighted  average  life.  In  general,  if  the weighted
                        average life  of  a  Certificate  purchased  at  par  is
                        extended   beyond   that  initially   anticipated,  such
                        Certificate's market  value  may be  adversely  affected
                        even  though the yield to maturity on the Certificate is
                        unaffected. The weighted  average lives  of the  Offered
                        Certificates,  under  various prepayment  scenarios, are
                        displayed in  the  tables appearing  under  the  heading
                        "Prepayment and Yield Considerations."

                        and each subclass  of the Class  B Certificates will  be
                        designated  as the  regular interests in  the REMIC, and
                        the Class  A-R Certificate  will  be designated  as  the
                        residual interest in the REMIC.
                        Beneficial   owners  of  the  Regular  Certificates  (as
                        defined  herein)  will  be  required  to  report  income

                        accounting. The Class A-10  Certificates will be  issued
                        with  original  issue  discount for  federal  income tax
                        purposes in  an  amount  equal  to  the  excess  of  all
                        distributions of principal and interest thereon (whether
                        current  or accrued)  over their  issue price (including
                        accrued interest). It is anticipated that the Class A-7,
                        Class A-8, Class A-9 and Class A-13 Certificates and the
                        Class M Certificates will be issued with original  issue

                        The holder of the Class A-R Certificate will be required
                        to include the taxable  income or loss  of the REMIC  in
                        determining   its   federal   taxable   income.   It  is
                        anticipated that
                        all of the taxable income of the REMIC includible by the
                        Class A-R Certificateholder will  be treated as  "excess
                        inclusion"  income  subject to  special  limitations for
                        federal  income  tax   purposes.  FURTHER,   SIGNIFICANT

                        DESCRIPTION OF THE CERTIFICATES
 
GENERAL
 
    The  Book-Entry Certificates  will be  issued only  in book-entry  form. The
Book-Entry Certificates, other than the  Class A-8 Certificates, will be  issued
in  minimum  denominations of  $100,000 initial  principal balance  and integral
multiples of $1,000 initial principal balance  in excess thereof. The Class  A-8
Certificates will be issued in minimum denominations of $1,000 initial principal
balance  and integral  multiples of $1,000  initial principal  balance in excess
thereof. Offered Certificates issued in fully registered, certificated form  are
referred  to herein as "Definitive Certificates."  The Class M Certificates will
be issued  as  Definitive  Certificates in  minimum  denominations  of  $100,000
initial  principal balance  and integral  multiples of  $1,000 initial principal
balance in excess thereof. The Class A-R Certificate will be issued as a  single
Definitive  Certificate  with  a denomination  of  $1,090,000  initial principal
balance.
 
    Each Subclass of Book-Entry Certificates initially will be represented by  a
single  physical certificate registered in  the name of Cede  & Co. ("Cede"), as
nominee of  DTC, which  will  be the  "holder"  or "Certificateholder"  of  such
Certificates,  as such terms are used herein. No person acquiring an interest in
the Book-Entry Certificates (a "Beneficial Owner") will be entitled to receive a
certificate representing such person's interest in the Book-Entry  Certificates,
except  as set forth  below under "--Definitive  Certificates." Unless and until
Definitive Certificates  are issued  under the  limited circumstances  described
herein,  all references to actions taken by Certificateholders or holders shall,
in the case of the Book-Entry Certificates,  refer to actions taken by DTC  upon
instructions from its Participants (as defined below), and all references herein
to  distributions,  notices,  reports and  statements  to  Certificateholders or
holders  shall,  in  the   case  of  the   Book-Entry  Certificates,  refer   to
distributions, notices, reports and statements to DTC or Cede, as the registered
holder  of the Book-Entry Certificates, as the  case may be, for distribution to
Beneficial  Owners  in  accordance   with  DTC  procedures.  See   "--Book-Entry
Registration" below.
 
BOOK-ENTRY REGISTRATION
 
    DTC is a limited purpose trust company organized under the laws of the State
of  New York, a member  of the Federal Reserve  System, a "clearing corporation"
within the  meaning of  the New  York  UCC and  a "clearing  agency"  registered
pursuant  to Section 17A of the Securities Exchange Act of 1934, as amended. DTC
was  created   to   hold   securities  for   its   participating   organizations
("Participants")  and to facilitate  the clearance and  settlement of securities
transactions  among  Participants   through  electronic  book-entries,   thereby
eliminating the need for physical movement of certificates. Participants include
securities  brokers  and  dealers  (including  the  Underwriter),  banks,  trust
companies and clearing corporations. Indirect access  to the DTC system also  is
available  to banks,  brokers, dealers,  trust companies  and other institutions
that clear  through or  maintain a  custodial relationship  with a  Participant,
either directly or indirectly ("Indirect Participants").
 
    Under  the rules, regulations and procedures  creating and affecting DTC and
its operations (the "Rules"),  DTC is required to  make book-entry transfers  of
Book-Entry  Certificates among Participants on whose behalf it acts with respect
to the  Book-Entry Certificates  and to  receive and  transmit distributions  of
principal  of  and interest  on  the Book-Entry  Certificates.  Participants and
Indirect Participants with which Beneficial Owners have accounts with respect to
the Book-Entry Certificates similarly are required to make book-entry  transfers
and  receive and transmit such payments on behalf of their respective Beneficial
Owners.
 
    Beneficial Owners that  are not  Participants or  Indirect Participants  but
desire  to purchase, sell or otherwise transfer ownership of, or other interests
in, Book-Entry Certificates  may do  so only through  Participants and  Indirect
Participants.  In addition, Beneficial Owners  will receive all distributions of
principal and interest from  the Servicer, or  a paying agent  on behalf of  the
Servicer,  through DTC Participants. DTC will  forward such distributions to its
Participants, which thereafter  will forward  them to  Indirect Participants  or
Beneficial  Owners. Beneficial Owners will not be recognized by the Trustee, the
 
                                      S-18
<PAGE>
Servicer or any paying agent as Certificateholders, as such term is used in  the
Pooling  and Servicing  Agreement, and  Beneficial Owners  will be  permitted to
exercise the rights of  Certificateholders only indirectly  through DTC and  its
Participants.
 
    Because  DTC can  only act  on behalf  of Participants,  who in  turn act on
behalf of Indirect Participants and certain  banks, the ability of a  Beneficial
Owner  to  pledge Book-Entry  Certificates to  persons or  entities that  do not
participate in  the  DTC  system, or  to  otherwise  act with  respect  to  such
Book-Entry  Certificates,  may  be  limited  due  to  the  lack  of  a  physical
certificate for such  Book-Entry Certificates. In  addition, under a  book-entry
format,  Beneficial Owners may  experience delays in  their receipt of payments,
since distributions will be made by the Servicer, or a paying agent on behalf of
the Servicer, to Cede, as nominee for DTC.
 
    DTC has advised  the Seller that  it will  take any action  permitted to  be
taken  by a Certificateholder under the  Pooling and Servicing Agreement only at
the direction  of  one or  more  Participants to  whose  accounts with  DTC  the
Book-Entry  Certificates are credited. Additionally,  DTC has advised the Seller
that it will take such actions  with respect to specified Voting Interests  only
at  the direction of and on behalf  of Participants whose holdings of Book-Entry
Certificates evidence such specified Voting Interests. DTC may take  conflicting
actions  with respect to Voting Interests  to the extent that Participants whose
holdings of  Book-Entry Certificates  evidence such  Voting Interests  authorize
divergent action.
 
    Neither   the  Seller,   the  Servicer  nor   the  Trustee   will  have  any
responsibility for any  aspect of the  records relating to  or payments made  on
account of beneficial ownership interests of the Book-Entry Certificates held by
Cede,  as  nominee for  DTC, or  for maintaining,  supervising or  reviewing any
records relating to such beneficial ownership interests.
 
DEFINITIVE CERTIFICATES
 
    The Class A-R  Certificate and the  Class M Certificates  will be issued  as
Definitive  Certificates. Further, Book-Entry Certificates  will be converted to
Definitive Certificates and  re-issued to Beneficial  Owners or their  nominees,
rather  than to DTC or its nominee, only if (i) the Servicer advises the Trustee
in writing that  DTC is  no longer  willing or  able to  discharge properly  its
responsibilities  as depository with respect  to the Book-Entry Certificates and
the Servicer is unable  to locate a qualified  successor, (ii) the Servicer,  at
its option, elects to terminate the book-entry system through DTC or (iii) after
the  occurrence of a dismissal or resignation  of the Servicer under the Pooling
and Servicing Agreement, Beneficial Owners representing not less than 51% of the
Voting Interests of each outstanding class of Book-Entry Certificates advise the
Trustee through DTC, in  writing, that the continuation  of a book-entry  system
through DTC (or a successor thereto) is no longer in the Beneficial Owners' best
interest.
 
    Upon  the occurrence  of any  event described  in the  immediately preceding
paragraph, the Trustee will be required to notify all Beneficial Owners  through
Participants  of the availability of  Definitive Certificates. Upon surrender by
DTC of the definitive certificates representing the Book-Entry Certificates  and
receipt  of  instructions  for  re-registration, the  Trustee  will  reissue the
Book-Entry  Certificates  as  Definitive  Certificates  to  Beneficial   Owners.
Distributions of principal of, and interest on, the Book-Entry Certificates will
thereafter be made by the Servicer, or a paying agent on behalf of the Servicer,
directly to holders of Definitive Certificates in accordance with the procedures
set forth in the Pooling and Servicing Agreement.
 
    Definitive Certificates will be transferable and exchangeable at the offices
of  the Trustee or the certificate registrar.  No service charge will be imposed
for any  registration of  transfer  or exchange,  but  the Trustee  may  require
payment  of  a sum  sufficient to  cover  any tax  or other  governmental charge
imposed in connection therewith.
 
DISTRIBUTIONS
 
    Distributions of interest and in  reduction of principal balance to  holders
of  Class A Certificates of each Subclass will be made monthly, to the extent of
each Subclass' entitlement thereto, on  the 25th day of  each month or, if  such
day is not a business day, on the succeeding business day (each, a "Distribution
Date"),  beginning in  June 1992, in  an aggregate  amount equal to  the Class A
Distribution Amount.
 
                                      S-19
<PAGE>
Distributions of interest and  in reduction of principal  balance to holders  of
Class  M  Certificates  will be  made  monthly, to  the  extent of  the  Class M
Certificates' entitlement thereto,  on each  Distribution Date  in an  aggregate
amount  equal to the Class M Distribution Amount after all amounts in respect of
interest and principal  due on the  Class A Certificates  for such  Distribution
Date including all previously unpaid Class A Subclass Interest Shortfall Amounts
with  respect  to any  Subclass  of Class  A  Certificates have  been  paid. The
"Determination Date" with respect to each Distribution Date will be the 17th day
of each month, or if such day is not a business day, the preceding business day.
Distributions will  be made  on  each Distribution  Date  to holders  of  record
(which, in the case of the Book-Entry Certificates, will be Cede, as nominee for
DTC)  at the close of business  on the last day of  the preceding month (each, a
"Record Date"), except that  the final distribution in  respect of each Class  A
Certificate  of any Subclass and each Class M Certificate will only be made upon
presentation and surrender of such Class A or Class M Certificate at the  office
or  agency  appointed  by the  Trustee  and  specified in  the  notice  of final
distribution in respect  of such  Subclass of Class  A Certificates  or Class  M
Certificate.
 
    The  aggregate amount  available for  distribution to  Certificateholders on
each  Distribution  Date  will  be  the  Pool  Distribution  Amount.  The  "Pool
Distribution  Amount" for a Distribution Date will  be the sum of all previously
undistributed payments  or other  receipts on  account of  principal  (including
principal  prepayments and Liquidation Proceeds in respect of principal, if any)
and interest on or  in respect of  the Mortgage Loans  received by the  Servicer
after the Cut-Off Date (except for amounts due on or prior to the Cut-Off Date),
or  received by the Servicer on  or prior to the Cut-Off  Date but due after the
Cut-Off Date, in either case received on  or prior to the Determination Date  in
the month in which such Distribution Date occurs, plus (i) all Periodic Advances
made  by the Servicer  and (ii) all other  amounts required to  be placed in the

    On  each Distribution Date,  the Pool Distribution  Amount will be allocated
among the Classes  of Certificates  and distributed  to the  holders thereof  of
record  as of the related Record Date  as follows (the "Pool Distribution Amount
Allocation"):
 
        FIRST, to each Subclass of Class A Certificates, pro rata based on their
    respective Class A Subclass Interest Accrual Amounts, in an aggregate amount
    up to the sum of the Class A Subclass Interest Accrual Amounts with  respect
    to such Distribution Date; provided, that prior to the Accretion Termination
    Date,  the amount of  interest that would otherwise  be distributable to the
    Accrual Certificates will instead be distributed in reduction of the Class A
    Subclass Principal  Balance  of  the Subclass  or  Subclasses  of  Accretion
    Directed Certificates then entitled to receive distributions in reduction of
    principal  balance in accordance  with the priorities  set forth below under
    "--Principal (Including Prepayments)--Allocation of Amount to be Distributed
    to the Class A and Class M Certificates;"
 
        SECOND, to each  Subclass of  Class A  Certificates, pro  rata based  on
    their  respective unpaid Class A Subclass  Interest Shortfall Amounts, in an
    aggregate amount up  to the sum  of the previously  unpaid Class A  Subclass
    Interest   Shortfall  Amounts;   provided,  that  prior   to  the  Accretion
    Termination Date, the amount  that would otherwise  be distributable to  the
    Accrual  Certificates pursuant to this provision will instead be distributed
    in reduction of the  Class A Subclass Principal  Balance of the Subclass  or
    Subclasses  of  Accretion  Directed Certificates  then  entitled  to receive
    distributions in  reduction  of principal  balance  in accordance  with  the
    priorities set forth below under "--Principal (Including
    Prepayments)--Allocation  of Amount  to be  Distributed to  the Class  A and
    Class M Certificates;"
 
        THIRD, to each Subclass of Class A Certificates, in an aggregate  amount
    up  to  the  Class  A  Optimal Principal  Amount,  such  distribution  to be
    allocated among such Subclasses in accordance with the priorities set  forth
    below under "--Principal (Including Prepayments)--Allocation of Amount to be
    Distributed to the Class A and Class M Certificates;"
 
        FOURTH, to the Class M Certificates in amount up to the Class M Interest
    Accrual Amount with respect to such Distribution Date;
 
        FIFTH,  to the Class  M Certificates in  an amount up  to the previously
    unpaid Class M Interest Shortfall Amount;
 
        SIXTH, to  the Class  M Certificates  in an  amount up  to the  Class  M
    Optimal Principal Amount; and
 
        SEVENTH,  sequentially to the Class B-1,  Class B-2, Class B-3 and Class
    B-4 Certificates so that each subclass  shall receive first an amount up  to
    its   Class  B  Subclass  Interest  Accrual  Amount  with  respect  to  such
    Distribution Date, second  an amount  up to its  previously unpaid  subclass
    interest  shortfall amount  and then  an amount  up to  its subclass optimal
    principal amount before any subclasses of Class B Certificates with a higher
    numerical designation  receive  any  payments  in  respect  of  interest  or
    principal.
 
    The "Class A Distribution Amount" for any Distribution Date will be equal to
the  sum of the amounts distributed  in accordance with priorities FIRST through
THIRD of the Pool Distribution Amount Allocation set forth above.
 
    The "Class M Distribution Amount" for any Distribution Date will be equal to
the sum of the amounts distributed in accordance with priorities FOURTH  through
SIXTH of the Pool Distribution Amount Allocation set forth above.
 
    The undivided percentage interest (the "Percentage Interest") represented by
any Class A Certificate of a Subclass or Class M Certificate in distributions to
such  Subclass or Class will be equal to the percentage obtained by dividing the
initial principal balance of such Certificate by the aggregate initial principal
balance of all Certificates of such Subclass or Class, as the case may be.

    No holder of  an Offered Certificate  will have any  right to request  early
distributions  in reduction of principal balance  and/or interest of any Offered
Certificate for  any  reason  whatsoever  (including the  death  of  the  holder
thereof), and neither the Trustee, the Seller nor the Servicer will be permitted
to  honor any  such request  received. Distributions  in reduction  of principal
balance of  each Subclass  and Class  of Offered  Certificates will  be made  as
described  herein.  No Offered  Certificates of  any Subclass  or Class  will be
selected to receive distributions by random lot.
 
INTEREST
 
    The amount  of  interest which  will  accrue on  each  Subclass of  Class  A
Certificates  during each month is  referred to herein as  the "Class A Subclass
Interest Accrual  Amount"  for such  Subclass.  The Class  A  Subclass  Interest
Accrual  Amount for each Subclass of  Offered Certificates, other than the Class
A-R Certificate, will equal the product  of (i) 1/12th of the Pass-Through  Rate
for such Subclass and (ii) the outstanding Class A Subclass Principal Balance of
such  Subclass. The Pass-Through  Rate for each such  Subclass is the percentage
set forth  on the  cover of  this Prospectus  Supplement. The  Class A  Subclass
Interest  Accrual Amount for the Class A-R Certificate will equal the product of
(i) 1/12th of 8.00% and (ii) the Class A-R Notional Amount. The Class A Subclass
Interest Accrual Amount for the Class  A-14 Certificates will equal the  product
of (i) 1/12th of (a) the weighted average of the Net Mortgage Interest Rates (as
defined  below) of the Mortgage  Loans as of the first  day of such period minus
(b) 8.00%  and  (ii) the  Class  A-14 Notional  Amount.  Each Class  A  Subclass
Interest  Accrual Amount will be reduced by the portion of (i) any Non-Supported
Interest Shortfall allocable to such Subclass  and (ii) the interest portion  of
Excess  Special Hazard Losses, Excess Fraud  Losses and Excess Bankruptcy Losses
allocable to such Subclass.
 
    The amount of interest which will accrue on the Class M Certificates  during
each  month is referred to herein as  the "Class M Interest Accrual Amount." The
Class M Interest Accrual Amount  will equal the product  of (i) 1/12th of  8.00%
and (ii) the outstanding Class M Principal Balance. The Class M Interest Accrual
Amount  will  be  reduced  by  (i) the  portion  of  any  Non-Supported Interest
Shortfall allocable to the Class M Certificates and (ii) the interest portion of
Excess Special Hazard Losses, Excess  Fraud Losses and Excess Bankruptcy  Losses
allocable to the Class M Certificates.
 
    Each subclass of Class B Certificates will accrue interest during each month
at  a Pass-Through Rate  of 8.00% per  annum. The amount  of interest accrued on
each subclass during each month (the "Class B Subclass Interest Accrual Amount")
will equal the product of (i) 1/12th  of 8.00% and (ii) the outstanding Class  B
Subclass  Principal Balance  of such  subclass. Each  Class B  Subclass Interest
Accrual Amount will be reduced by (i) the portion of any Non-Supported  Interest
Shortfalls  allocable to such  subclass and (ii) the  interest portion of Excess
Special  Hazard  Losses,  Excess  Fraud  Losses  and  Excess  Bankruptcy  Losses
allocable to such subclass as described below.
 
    The  "Class  A  Subclass  Principal  Balance"  of  a  Subclass  of  Class  A
Certificates as of any Determination Date will be the principal balance of  such
Subclass  on the date of  initial issuance of the  Class A Certificates plus, in
the case of the  Accrual Certificates, the portion  of the Accrual  Distribution
Amount,   as  described  under   "--Principal  (Including  Prepayments)"  below,
previously added  to the  Class  A Subclass  Principal  Balance of  the  Accrual
Certificates,  less  (i)  all  amounts  previously  distributed  to  holders  of
Certificates of such  Subclass in  reduction of  the principal  balance of  such
Subclass  and (ii)  such Subclass'  pro rata share  of the  principal portion of
Excess Special Hazard Losses, Excess  Fraud Losses and Excess Bankruptcy  Losses
previously  allocated  to the  holders  of Class  A  Certificates in  the manner
described   herein   under   "--Subordination   of   Class   M   and   Class   B
Certificates--Allocation  of  Losses." After  the Cross-Over  Date, the  Class A
Subclass Principal Balance of a Subclass may be subject to further reduction  in
an  amount equal  to such Subclass'  pro rata  share of the  difference, if any,
between (a) the Class A Principal Balance as of such Determination Date  without
regard  to this  provision and  (b) the Adjusted  Pool Amount  for the preceding
Distribution Date.  Any pro  rata allocation  among the  Subclasses of  Class  A
Certificates  described in this  paragraph will be made  among the Subclasses of
 
                                      S-22
<PAGE>
Class A Certificates  on the basis  of their then-outstanding  Class A  Subclass
Principal  Balances immediately prior to the applicable Distribution Date, or in
the case of the Accrual Certificates,  their initial Class A Subclass  Principal
Balance, if lower.
 
    The  "Class A Principal Balance" as of  any Determination Date will be equal
to the sum of the Class A Subclass Principal Balances of the Subclasses of Class
A Certificates as of such date.
 
    The "Class M  Principal Balance" as  of any Determination  Date will be  the
lesser  of (a) the principal balance of the  Class M Certificates on the date of
initial issuance of  the Class M  Certificates less (i)  all amounts  previously
distributed  to holders  of Class M  Certificates in reduction  of the principal
balance thereof and (ii) the principal portion of Excess Special Hazard  Losses,
Excess  Fraud Losses  and Excess Bankruptcy  Losses previously  allocated to the
holders of  the  Class M  Certificates  in  the manner  described  herein  under
"--Subordination  of Class M and Class B Certificates--Allocation of Losses" and
(b) the Adjusted  Pool Amount  as of the  preceding Distribution  Date less  the
Class A Principal Balance as of such Determination Date.
 
    The  "Class  B  Subclass  Principal  Balance"  of  a  subclass  of  Class  B
Certificates as of any Determination Date will be the lesser of (a) the  initial
principal  balance of such subclass on the date of initial issuance of the Class
B Certificates less (i)  all amounts previously distributed  to holders of  such
subclass  in reduction of  the principal balance thereof  and (ii) the principal
portion of  Excess  Special  Hazard  Losses,  Excess  Fraud  Losses  and  Excess
Bankruptcy  Losses previously allocated  to the holders of  such subclass in the
manner described under "--Subordination  of Class M  and Class B  Certificates--
Allocation  of Losses"  and (b)  the Adjusted  Pool Amount  as of  the preceding
Distribution Date less the  sum of the  Class A Principal  Balance, the Class  M
Principal  Balance and the Class B Subclass Principal Balances of the subclasses
of Class B Certificates with lower numerical designations.
 
    The "Class B Principal Balance" as of any  date will be equal to the sum  of
the Class B Subclass Principal Balance of the subclasses of Class B Certificates
as of such date.
 
    With respect to any Distribution Date, The "Adjusted Pool Amount" will equal
the Cut-Off Date Aggregate Principal Balance of the Mortgage Loans minus the sum
of  (i) all amounts in respect of  principal received in respect of the Mortgage
Loans (including amounts  received as Periodic  Advances, principal  prepayments
and  Liquidation Proceeds in respect of principal) and distributed to holders of
the Series  1992-14  Certificates  on  such  Distribution  Date  and  all  prior
Distribution  Dates  and  (ii)  the principal  portion  of  all  Realized Losses
incurred on the  Mortgage Loans from  the Cut-Off  Date through the  end of  the
month preceding such Distribution Date.
 
    The  "Net Mortgage Interest Rate" on each Mortgage Loan will be equal to the
Mortgage Interest Rate on such Mortgage  Loan as stated in the related  mortgage
note minus the Servicing Fee rate of 0.25% per annum. See "Pooling and Servicing
Agreement--Servicing Compensation and Payment of Expenses" herein.
 
    The "Class A-14 Notional Amount" with respect to each Distribution Date will
be  equal to the Pool Scheduled Principal Balance, as defined under "--Principal
(Including Prepayments)" below,  as of  such Distribution Date.  The Class  A-14
Notional   Amount  with  respect   to  the  first   Distribution  Date  will  be
approximately $476,354,867.
 
    The "Class A-R Notional Amount" with respect to each Distribution Date  will
be  equal to the sum of the Class  A Subclass Principal Balance of the Class A-R
Certificate and  the  Class A  Subclass  Principal  Balance of  the  Class  A-14
Certificates.   The  Class  A-R  Notional  Amount  with  respect  to  the  first
Distribution Date will be $1,091,000.
 
    Shortfalls in collections of interest  as a result of principal  prepayments
in  full of Mortgage Loans ("Prepayment  Interest Shortfalls") will be offset to
the extent of  the aggregate Servicing  Fees relating to  mortgagor payments  or
other  recoveries distributed  on the  related Distribution  Date. Shortfalls in
collections of interest as a result of the timing of partial prepayments on  the
Mortgage  Loans will not be so offset. To the extent of any such shortfalls as a
result   of    partial    prepayments   and    to    the   extent    that    the
 
                                      S-23
<PAGE>
aggregate  Prepayment Interest  Shortfalls with  respect to  a Distribution Date
exceed the  aggregate Servicing  Fees relating  to mortgagor  payments or  other
recoveries  distributed  on  such  Distribution  Date,  the  resulting  interest
shortfall (the "Non-Supported Interest Shortfall") will be allocated to (i)  the
Class  A Certificates according to  the Class A Percentage  and (ii) the Class M
Certificates  according   to   the   percentage   obtained   by   dividing   the
then-outstanding  Class M Principal  Balance by the  sum of the then-outstanding
Class A  Principal Balance,  Class M  Principal Balance  and Class  B  Principal
Balance.  Such allocation of  Non-Supported Interest Shortfalls  will reduce the
amount of interest due to be distributed to holders of the Class A  Certificates
and  Class  M  Certificates,  respectively, then  entitled  to  distributions in
respect of  interest and,  in the  case  of Accrual  Certificates prior  to  the
Accretion  Termination Date,  will reduce  the amount  accrued and  added to the
Class A Subclass  Principal Balance thereof.  Any such reduction  in respect  of
interest will be allocated among the Subclasses of Class A Certificates pro rata
on  the basis of their respective Class  A Subclass Interest Accrual Amounts for
such Distribution  Date. See  "Servicing of  the Mortgage  Loans--Adjustment  to
Servicing  Fee in Connection with Prepaid  and Liquidated Mortgage Loans" in the
Prospectus.
 
    The interest  portion of  any  Excess Special  Hazard Losses,  Excess  Fraud
Losses  or Excess Bankruptcy Losses will be allocated among the Class A, Class M
and Class B Certificates  pro rata based  on the interest  accrued on each  such
Class  and among the Subclasses of Class A Certificates pro rata on the basis of
their respective Class A Subclass Interest Accrual Amounts for such Distribution
Date.
 
    Allocations of the interest  portion of Realized  Losses (other than  Excess
Special Hazard Losses, Excess Fraud Losses or Excess Bankruptcy Losses) first to
the  Class B Certificates and then to  the Class M Certificates will result from
the priority of distributions first to  the Class A Certificateholders and  then
to  the Class M Certificateholders of  the Pool Distribution Amount as described
above under "-- Distributions."
 
    On each Distribution Date  on which the Pool  Distribution Amount equals  or
exceeds  the sum of the Class A Subclass Interest Accrual Amounts, distributions
in respect of interest to each Subclass  of Class A Certificates other than  the
Accrual Certificates will equal such Subclass' Class A Subclass Interest Accrual
Amount. On each such Distribution Date, interest in an amount equal to its Class
A  Subclass Interest Accrual Amount will accrue on the Accrual Certificates, but
such amount will  not be  distributed as  interest to  the Accrual  Certificates
until  the Accretion Termination Date. "The  Accretion Termination Date" will be
the earlier of (i) the Distribution Date on which the Class A Subclass Principal
Balance of the Class  A-13 Certificates has  been reduced to  zero and (ii)  the
Cross-Over  Date. Prior to  such time, an  amount equal to  the Class A Subclass
Interest Accrual Amount for the Accrual Certificates will not be distributed  as
interest  to  the  holders of  the  Accrual  Certificates, but  will  instead be
distributed in  reduction of  the  Class A  Subclass  Principal Balance  of  the
Subclass  or  Subclasses of  Accretion  Directed Certificates  then  entitled to
receive distributions  in  reduction of  principal  balance as  described  under
"--Principal  (Including Prepayments)" below, and the Class A Subclass Principal
Balance of the Accrual Certificates will be increased by a corresponding amount.
 
    If, on any Distribution Date, the Pool Distribution Amount is less than  the
sum  of the Class  A Subclass Interest  Accrual Amounts, the  amount of interest
currently  distributed  on  the  Class  A  Certificates  will  equal  the   Pool
Distribution  Amount  and will  be  allocated among  the  Subclasses of  Class A
Certificates pro rata in  accordance with each such  Subclass' Class A  Subclass
Interest  Accrual Amount. Amounts so allocated will be distributed in respect of
interest to each  Subclass of Class  A Certificates, with  the exception of  the
Accrual Certificates prior to the Accretion Termination Date. In the case of the
Accrual  Certificates  prior  to  the  Accretion  Termination  Date,  amounts so
allocated will be added to the Class A Subclass Principal Balance of the Accrual
Certificates and  distributed as  principal  to the  Subclass or  Subclasses  of
Accretion  Directed  Certificates  then  entitled  to  receive  distributions in
reduction of principal balance. See "--Principal (Including Prepayments)" below.
Any difference between the portion  of the Pool Distribution Amount  distributed
in  respect of current interest to each  Subclass of Class A Certificates or, in
the case of the  Accrual Certificates prior to  the Accretion Termination  Date,
accrued  on and added to the Class A Subclass Principal Balance thereof, and the
Class A Subclass Interest Accrual Amounts for such Subclass with respect to  the
related Distribution Date (as to each
 
                                      S-24
<PAGE>
Subclass,  the "Class A  Subclass Interest Shortfall Amount"),  will be added to
the amount to be distributed on subsequent Distribution Dates to the extent that
the Pool Distribution Amount is sufficient therefor. No interest will accrue  on
the unpaid Class A Subclass Interest Shortfall Amounts. In the event that on any
Distribution  Date prior to the Accretion Termination Date the Pool Distribution
Amount is less than the  sum of the Class  A Subclass Interest Accrual  Amounts,
resulting in Class A Subclass Interest Shortfall Amounts, as described above, an
amount  equal to  the Accrual  Distribution Amount  would be  distributed to the
Subclass or  Subclasses  of Accretion  Directed  Certificates then  entitled  to
receive  distributions in  reduction of principal  balance, notwithstanding that
the  holders  of  Certificates  of  the  Subclasses  then  entitled  to  receive
distributions  of  interest have  received less  than  their respective  Class A
Subclass Interest Accrual Amounts with respect to such Distribution Date.
 
    On each Distribution Date on which the Pool Distribution Amount exceeds  the
sum  of the Class A  Subclass Interest Accrual Amounts,  any excess will then be
allocated first to  pay previously  unpaid Class A  Subclass Interest  Shortfall
Amounts.  Such  amounts  will  be  allocated among  the  Subclasses  of  Class A
Certificates pro rata in accordance with the respective unpaid Class A  Subclass
Interest Shortfall Amounts immediately prior to such Distribution Date. Prior to
the  Accretion  Termination  Date,  the  amount  so  allocated  to  the  Accrual
Certificates will not be distributed as  interest to the holders of the  Accrual
Certificates,  but  will instead  be  distributed in  reduction  of the  Class A
Subclass Principal Balance of the  Subclass or Subclasses of Accretion  Directed
Certificates  then entitled to  receive distributions in  reduction of principal
balance, and the Class A Subclass Principal Balance of the Accrual  Certificates
will be increased by a corresponding amount.
 
    On  each Distribution Date  on which the Pool  Distribution Amount equals or
exceeds the sum  of (i) the  Class A Distribution  Amount and (ii)  the Class  M
Interest  Accrual Amount,  distributions in respect  of current  interest to the
Class M Certificates will equal the Class M Interest Accrual Amount.
 
    If, on any Distribution Date, the Pool Distribution Amount is less than  the
sum of (i) the Class A Distribution Amount and (ii) the Class M Interest Accrual
Amount,  the amount of current interest  distributed on the Class M Certificates
will equal the  Pool Distribution Amount  minus the amounts  distributed to  the
Class  A Certificates  with respect  to such  Distribution Date.  Any difference
between the portion of  the Pool Distribution Amount  distributed in respect  of
current  interest to the Class  M Certificates and the  Class M Interest Accrual
Amount with respect to such Distribution  Date (the "Class M Interest  Shortfall
Amount"),  will  be  added  to  the  amount  to  be  distributed  on  subsequent
Distribution Dates to the extent that the Pool Distribution Amount is sufficient
therefor. No  interest will  accrue on  the unpaid  Class M  Interest  Shortfall
Amount.
 
    On  each Distribution Date on which the Pool Distribution Amount exceeds the
sum of the Class A Distribution Amount and the Class M Interest Accrual  Amount,
any  excess will be  allocated first to  pay previously unpaid  Class M Interest
Shortfall Amounts and then to make distributions in respect of principal on  the
Class  M  Certificates and  in respect  of  interest and  then principal  on the
subclasses of Class B Certificates.
 
    On any Distribution Date on which the Pool Distribution Amount is less  than
the  Class A Distribution Amount, the Class M Certificates and the subclasses of
Class B Certificates will  not be entitled to  any distributions of interest  or
principal.
 
PRINCIPAL (INCLUDING PREPAYMENTS)
 
    The  principal balance of  a Class A  Certificate of any  Subclass or of any
Class M Certificate at any time is equal to the product of the Class A  Subclass
Principal Balance of such Subclass or the Class M Principal Balance, as the case
may  be, and such Certificate's Percentage  Interest, and represents the maximum
specified dollar amount (exclusive of (i)  any interest that may accrue on  such
Class A Certificate (other than interest added to the Class A Subclass Principal
Balance of the Accrual Certificates) or Class M Certificate and (ii) in the case
of  the Class A-R Certificate,  any additional amounts to  which a holder of the
Class A-R Certificate  may be  entitled as described  below under  "--Additional
Rights  of  the Class  A-R Certificateholder")  to which  the holder  thereof is
entitled from the cash flow on
 
                                      S-25
<PAGE>
the Mortgage Loans at such time, and will decline to the extent of distributions
in reduction of  the principal balance  of, and allocations  of losses to,  such
Certificate.  The approximate initial Class A Subclass Principal Balance of each
Subclass of Class A  Certificates (other than the  Class A-14 Certificates)  and
the  approximate initial Class M Principal Balance are set forth on the cover of
this Prospectus Supplement. The  initial Class A  Subclass Principal Balance  of
the Class A-14 Certificates is $1,000.
 
  CALCULATION OF AMOUNT TO BE DISTRIBUTED TO THE CLASS A CERTIFICATES
 
    Distributions  in  reduction  of  the  principal  balance  of  the  Class  A
Certificates will be made on each Distribution Date in an aggregate amount equal
to  the  Class  A  Principal   Distribution  Amount.  The  "Class  A   Principal
Distribution  Amount" with respect to any Distribution Date will be equal to the
sum of  (i)  the Accrual  Distribution  Amount, if  any,  with respect  to  such
Distribution  Date and (ii)  the Class A  Principal Amount with  respect to such
Distribution Date.  The  "Accrual  Distribution  Amount"  with  respect  to  any
Distribution  Date will  be equal  to the  sum of  (i) the  portion, if  any, of
current interest allocated but  not distributed to  the Accrual Certificates  on
such   Distribution  Date  in  accordance  with   priority  FIRST  of  the  Pool
Distribution Amount Allocation and (ii) the portion, if any, of the unpaid Class
A Interest  Shortfall  Amount  allocated  but not  distributed  to  the  Accrual
Certificates on such Distribution Date in accordance with priority SECOND of the
Pool Distribution Amount Allocation. The "Class A Principal Amount" with respect
to  any Distribution Date  will be equal  to the amount  distributed pursuant to
priority THIRD  of the  Pool  Distribution Amount  Allocation, in  an  aggregate
amount up to the Class A Optimal Principal Amount.
 
    The  "Class A  Optimal Principal Amount"  with respect  to each Distribution
Date will be an amount equal to the sum of (i) the Class A Percentage of (A) all
scheduled payments of principal due on each outstanding Mortgage Loan (including
each defaulted Mortgage  Loan, other  than a  Liquidated Loan,  with respect  to
which  the related Mortgaged Property has been  acquired by the Trust Estate) on
the first day of the  month in which the Distribution  Date occurs, less (B)  if
the  Bankruptcy Coverage Termination Date has occurred, the principal portion of
Debt Service Reductions, (ii) the Class A Prepayment Percentage of the Scheduled
Principal Balance of each  Mortgage Loan which, during  the month preceding  the
month  of such  Distribution Date  was repurchased  by the  Seller, as described
under the heading "The Trust  Estates--Mortgage Loans" in the Prospectus,  (iii)
the  Class A Prepayment Percentage of  the aggregate net Liquidation Proceeds on
all Mortgage  Loans that  became Liquidated  Loans during  such preceding  month
(excluding  the portion thereof, if  any, constituting Net Foreclosure Profits),
less the amounts allocable  to principal of  any unreimbursed Periodic  Advances
previously  made by the Servicer  with respect to such  Liquidated Loans and the
portion of the net Liquidation Proceeds allocable to interest, (iv) the Class  A
Prepayment  Percentage of an  amount equal to the  principal portion of Realized
Losses (other than Bankruptcy Losses due to Debt Service Reductions) incurred in
such preceding  month other  than  Excess Special  Hazard Losses,  Excess  Fraud
Losses  and Excess Bankruptcy  Losses, (v) the Class  A Prepayment Percentage of
the Scheduled Principal Balance of each Mortgage Loan which was the subject of a
principal prepayment  in full  during  the month  preceding  the month  of  such
Distribution  Date,  (vi)  the  Class A  Prepayment  Percentage  of  all partial
principal prepayments  applied  by  the  Servicer in  reduction  of  the  unpaid
principal  balance  of any  Mortgage  Loan on  or  after the  Determination Date
occurring in  the month  preceding the  month in  which such  Distribution  Date
occurs  and prior to the Determination Date occurring in the month in which such
Distribution Date occurs  and (vii)  the Class  A Percentage  of the  difference
between  the unpaid  principal balance  of any  Mortgage Loan  substituted for a
defective Mortgage  Loan during  the month  preceding the  month in  which  such
Distribution  Date occurs  and the  unpaid principal  balance of  such defective
Mortgage Loan,  less the  amounts  allocable to  principal of  any  unreimbursed
Periodic  Advances with respect to such  defective Mortgage Loan. See "The Trust
Estates--Mortgage Loans--Assignment of  Mortgage Loans  to the  Trustee" in  the
Prospectus. In addition, in the event that there is any recovery of an amount in
respect  of principal which had previously been  allocated as a Realized Loss to
the Class  A  Certificates, each  Subclass  of  the Class  A  Certificates  then
outstanding will be entitled to its pro rata share of such recovery in an amount
up  to  the amount  by  which the  Class A  Subclass  Principal Balance  of such
Subclass was reduced as a result of such Realized Loss.

    The "Scheduled Principal Balance" of a Mortgage Loan as of any  Distribution
Date  is the unpaid principal balance of  such Mortgage Loan as specified in the
amortization schedule at  the time  relating thereto (before  any adjustment  to
such  schedule  by  reason  of  bankruptcy  (other  than  Deficient Valuations),
moratorium or similar waiver or  grace period) as of  the Due Date occurring  in
the  month preceding  the month  in which  such Distribution  Date occurs, after
giving effect to any  principal prepayments or  other unscheduled recoveries  of
principal previously received, to any partial prepayments applied as of such Due
Date,  Deficient Valuations occurring prior to such  Due Date and to the payment
of principal  due on  such Due  Date,  and irrespective  of any  delinquency  in
payment by the mortgagor.
 
    A  "Liquidated Loan" is a  defaulted Mortgage Loan as  to which the Servicer
has determined that all recoverable liquidation and insurance proceeds have been
received. A "Liquidated Loan Loss" on a Liquidated Loan is equal to the  excess,
if  any,  of (i)  the unpaid  principal  balance of  such Liquidated  Loan, plus
interest thereon  in  accordance  with  the amortization  schedule  at  the  Net
Mortgage  Interest Rate through the last day of the month in which such Mortgage
Loan was  liquidated,  over  (ii)  net Liquidation  Proceeds.  For  purposes  of
calculating the amount of any Liquidated Loan Loss, all net Liquidation Proceeds
(after  reimbursement to the  Servicer for any  previously unreimbursed advance)
will be  applied first  to accrued  interest and  then to  the unpaid  principal
balance  of the Liquidated  Loan. A "Special  Hazard Loss" is  a Liquidated Loan
Loss occurring as  a result of  a hazard  not insured against  under a  standard
hazard insurance policy of the type described in the Prospectus under "The Trust
Estates--  Mortgage Loans--Insurance Policies".  A "Fraud Loss"  is a Liquidated
Loan Loss incurred  on a  Liquidated Loan  as to which  there was  fraud in  the
origination of such Mortgage Loan. A "Bankruptcy Loss" is a loss attributable to
certain  actions which may be  taken by a bankruptcy  court in connection with a
Mortgage Loan, including  a reduction  by a  bankruptcy court  of the  principal
balance  of or  the interest  rate on  a Mortgage  Loan or  an extension  of its
maturity. A "Debt Service Reduction" means a reduction in the amount of  monthly
payments  due  to  certain  bankruptcy proceedings,  but  does  not  include any
permanent forgiveness of principal.  A "Deficient Valuation"  with respect to  a
Mortgage  Loan means  a valuation  by a  court of  the Mortgaged  Property in an
amount less than  the outstanding indebtedness  under the Mortgage  Loan or  any
reduction  in  the  amount  of  monthly payments  that  results  in  a permanent
forgiveness of principal, which valuation or reduction results from a bankruptcy
proceeding. Liquidated Loan  Losses (including Special  Hazard Losses and  Fraud
Losses) and Bankruptcy Losses are referred to herein as "Realized Losses."
 
    The  "Class A Percentage"  for any Distribution Date  occurring prior to the
Cross-Over Date is the percentage (subject to rounding), which in no event  will
exceed  100%, obtained by dividing the Class A Principal Balance as of such date
(before taking into account distributions  in reduction of principal balance  on
such  date) by the aggregate Scheduled  Principal Balances of all Mortgage Loans
for such Distribution Date (the "Pool Scheduled Principal Balance"). The Class A
Percentage for the  first Distribution  Date will be  approximately 91.50%.  The
Class  A  Percentage will  decrease as  a  result of  the allocation  of certain
unscheduled  payments  in  respect  of  principal  at  the  Class  A  Prepayment
Percentage  for a specified period to the Class A Certificates and will increase
as a result of the allocation of Realized Losses to the Class B and the Class  M
Certificates.  The Class A Percentage for each Distribution Date occurring on or
after the Cross-Over Date will be 100%.
 
    The "Class  A Prepayment  Percentage" for  any Distribution  Date  occurring
during  the five years beginning on the  first Distribution Date will, except as
provided below, equal 100%. Thereafter,  the Class A Prepayment Percentage  will
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 Class A
Certificates while, in the absence of Realized Losses, increasing the respective
interest in the principal balance of the Mortgage Loans evidenced by the Class M
and Class B Certificates. Increasing the respective interest of the Class M  and
Class B Certificates relative to that of the Class A Certificates is intended to
preserve the availability of the subordination provided by the Class M and Class
B Certificates. See "--Subordination of Class M and Class B Certificates" below.

    The  Class A 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  subsequent  to  May  1997  to  and  including  the
Distribution Date in May 1998, the Class A Percentage for such Distribution Date
plus 70% of  the Subordinated  Percentage for  such Distribution  Date; for  any
Distribution  Date subsequent to May 1998 to and including the Distribution Date
in May 1999, the Class A Percentage  for such Distribution Date plus 60% of  the
Subordinated  Percentage for such  Distribution Date; for  any Distribution Date
subsequent to May 1999 to and including  the Distribution Date in May 2000,  the
Class  A  Percentage for  such Distribution  Date plus  40% of  the Subordinated
Percentage for such Distribution Date;  for any Distribution Date subsequent  to
May  2000  to and  including  the Distribution  Date in  May  2001, the  Class A
Percentage for such Distribution  Date plus 20%  of the Subordinated  Percentage
for  such Distribution Date; and for any Distribution Date thereafter, the Class
A Percentage  for  such  Distribution  Date (unless  on  any  of  the  foregoing
Distribution   Dates  the  Class  A  Percentage  exceeds  the  initial  Class  A
Percentage,  in  which  case  the   Class  A  Prepayment  Percentage  for   such
Distribution  Date  will  once  again equal  100%).  See  "Prepayment  and Yield
Considerations" herein and in the Prospectus. Notwithstanding the foregoing,  no
reduction of the Class A Prepayment Percentage will occur if (i) as of the first
Distribution  Date as to which any such  reduction applies, more than an average
of 2% of the dollar amount of all monthly payments on the Mortgage Loans due  in
each  of the preceding twelve months were  delinquent 60 days or more (including
for this  purpose any  Mortgage Loans  in foreclosure  and Mortgage  Loans  with
respect  to which the related Mortgaged Property  has been acquired by the Trust
Estate), or (ii) Realized Losses with  respect to the Mortgage Loans exceed  (a)
with respect to the Distribution Date in June 1997, 30% of the principal balance
of  the  Subordinated  Certificates  as  of  the  Cut-Off  Date  (the  "Original
Subordinated Principal Balance"), (b) with  respect to the Distribution Date  in
June  1998, 35% of the Original Subordinated Principal Balance, (c) with respect
to the  Distribution  Date  in  June 1999,  40%  of  the  Original  Subordinated
Principal  Balance, (d) with respect to the  Distribution Date in June 2000, 45%
of the Original  Subordinated Principal  Balance, and  (e) with  respect to  the
Distribution  Date  in June  2001, 50%  of  the Original  Subordinated Principal
Balance. The  "Subordinated  Percentage"  for  any  Distribution  Date  will  be
calculated  as the difference between  100% and the Class  A Percentage for such
date. The "Subordinated Prepayment Percentage" for any Distribution Date will be
calculated as the difference between 100% and the Class A Prepayment  Percentage
for  such  date. If  on  any Distribution  Date the  allocation  to the  Class A
Certificates of full and partial principal prepayments and other amounts in  the
percentage required above would reduce the outstanding Class A Principal Balance
below zero, the Class A Prepayment Percentage for such Distribution Date will be
limited  to the percentage necessary to reduce  the Class A Principal Balance to
zero.  See  "Description  of   the  Certificates--Distributions  to   Percentage
Certificateholders--Shifting Interest Certificates" in the Prospectus.
 
  CALCULATION OF AMOUNT TO BE DISTRIBUTED TO THE CLASS M CERTIFICATES
 
    Distributions  in  reduction  of  the  principal  balance  of  the  Class  M
Certificates will be made on each Distribution Date, pursuant to priority  SIXTH
of the Pool Distribution Amount Allocation, in an aggregate amount (the "Class M
Principal Distribution Amount"), up to the Class M Optimal Principal Amount.
 
    The  "Class M  Optimal Principal Amount"  with respect  to each Distribution
Date will be an amount equal to the sum of (i) the Class M Percentage of (A) all
scheduled payments of principal due on each outstanding Mortgage Loan (including
each defaulted Mortgage  Loan, other  than a  Liquidated Loan,  with respect  to
which  the related Mortgaged Property has been  acquired by the Trust Estate) on
the first day of the  month in which the Distribution  Date occurs, less (B)  if
the  Bankruptcy Coverage Termination Date has occurred, the principal portion of
Debt Service Reductions, (ii) the Class M Prepayment Percentage of the Scheduled
Principal Balance of each  Mortgage Loan which, during  the month preceding  the
month  of such  Distribution Date  was repurchased  by the  Seller, as described
under the heading "The Trust  Estates--Mortgage Loans" in the Prospectus,  (iii)
the  Class M Prepayment Percentage of  the aggregate net Liquidation Proceeds on
all Mortgage  Loans that  became Liquidated  Loans during  such preceding  month
(excluding the portion thereof, if any, constituting Net Foreclosure Profits, as
defined  under "--Additional Rights of  the Class A-R Certificateholder" below),
less the amounts allocable  to principal of  any unreimbursed Periodic  Advances
previously made by the Servicer with
 
                                      S-28
<PAGE>
respect to such Liquidated Loans and the portion of the net Liquidation Proceeds
allocable  to Interest, (iv) on each Distribution Date prior to the reduction of
the Class B Principal Balance to zero,  the Class M Prepayment Percentage of  an
amount  equal to the principal portion of Realized Losses (other than Bankruptcy
Losses due to Debt  Service Reductions) incurred in  such preceding month  other
than  Excess Special  Hazard Losses, Excess  Fraud Losses  and Excess Bankruptcy
Losses, (v) the Class M Prepayment Percentage of the Scheduled Principal Balance
of each Mortgage Loan which  was the subject of  a principal prepayment in  full
during the month preceding the month of such Distribution Date, (vi) the Class M
Prepayment  Percentage  of  all  partial principal  prepayments  applied  by the
Servicer in reduction of the unpaid principal balance of any Mortgage Loan on or
after the Determination Date occurring in the month preceding the month in which
such Distribution Date occurs and prior  to the Determination Date occurring  in
the  month  in  which  such  Distribution Date  occurs  and  (vii)  the  Class M
Percentage of  the  difference  between  the unpaid  principal  balance  of  any
Mortgage  Loan  substituted  for  a defective  Mortgage  Loan  during  the month
preceding the  month in  which  such Distribution  Date  occurs and  the  unpaid
principal balance of such defective Mortgage Loan, less the amounts allocable to
principal  of any unreimbursed Periodic Advances  with respect to such defective
Mortgage Loan. See  "The Trust Estates--Mortgage  Loans--Assignment of  Mortgage
Loans to the Trustee" in the Prospectus. In addition, in the event that there is
any  recovery of  an amount  in respect of  principal which  had previously been
allocated as  a  Realized  Loss  to  the  Class  M  Certificates,  the  Class  M
Certificates will be entitled to their pro rata share of such recovery up to the
amount  by which the Class  M Principal Balance was reduced  as a result of such
Realized Loss.
 
    The "Class  M  Percentage"  and  "Class M  Prepayment  Percentage"  for  any
Distribution  Date will  equal that portion  of the  Subordinated Percentage and
Subordinated Prepayment  Percentage, as  the  case may  be, represented  by  the
fraction  the  numerator  of which  is  the then-outstanding  Class  M Principal
Balance and the denominator of which is the sum of the Class M Principal Balance
and the  Class B  Subclass  Principal Balances  of  the subclasses  entitled  to
principal   distributions  for  such  Distribution  Date  as  described  in  the
succeeding paragraph.
 
    In  the  event  that  on  any   Distribution  Date,  the  Current  Class   M
Subordination  Level is less than the  Original Class M Subordination Level, the
Class B-1, Class B-2, Class B-3 and Class B-4 Certificates will not be  entitled
to  distributions in  respect of  principal and  the Class  B Subclass Principal
Balances of such subclasses will not be used to determine the Class M Percentage
and  Class  M  Prepayment  Percentage  for  such  Distribution  Date.  For  such
Distribution Date, the Class M Percentage and Class M Prepayment Percentage will
equal  the Subordinated  Percentage and the  Subordinated Prepayment Percentage,
respectively. In the event that the  Current Class M Subordination Level  equals
or  exceeds the Original Class  M Subordination Level but  the Current Class B-1
Subordination Level is less than the Original Class B-1 Subordination Level, the
Class B-2,  Class  B-3  and Class  B-4  Certificates  will not  be  entitled  to
distributions  in  respect  of  principal and  the  Class  B  Subclass Principal
Balances of such subclasses will not be used to determine the Class M Percentage
and the Class M Prepayment Percentage  for such Distribution Date. In the  event
that  each of the Current Class M  Subordination Level and the Current Class B-1
Subordination Level equal or exceed the Original Class M Subordination Level and
the Original Class B-1 Subordination Level, respectively, but the Current  Class
B-2 Subordination Level is less than the Original Class B-2 Subordination Level,
the  Class B-3 and Class B-4 Certificates  will not be entitled to distributions
in respect of  principal and  the Class B  Subclass Principal  Balances of  such
subclasses  will not be used to determine the Class M Percentage and the Class M
Prepayment Percentage for such Distribution Date. Neither the Class B-3 nor  the
Class  B-4 Certificates will have original or current subordination levels which
are required to be maintained as described above.
 
    The "Original Class  M Subordination  Level" is the  percentage obtained  by
dividing the sum of the initial Class B Subclass Principal Balances of the Class
B-1,  Class  B-2, Class  B-3  and Class  B-4  Certificates by  the  Cut-Off Date
Aggregate Principal  Balance  of  the  Mortgage  Loans.  The  Original  Class  M
Subordination  Level is expected to be approximately 5.25%. The "Current Class M
Subordination Level" for  any Distribution  Date is the  percentage obtained  by
dividing the sum of the then-
 
                                      S-29
<PAGE>
outstanding  Class B  Subclass Principal Balances  of the Class  B-1, Class B-2,
Class B-3  and Class  B-4  Certificates by  the sum  of  the Class  A  Principal
Balance, the Class M Principal Balance and the Class B Principal Balance.
 
    The  "Original Class B-1 Subordination Level"  is the percentage obtained by
dividing the sum of the initial Class B Subclass Principal Balances of the Class
B-2, Class  B-3  and  Class  B-4 Certificates  by  the  Cut-Off  Date  Aggregate
Principal  Balance of the  Mortgage Loans. The  Original Class B-1 Subordination
Level  is  expected  to   be  approximately  3.75%.   The  "Current  Class   B-1
Subordination  Level" for  any Distribution Date  is the  percentage obtained by
dividing the sum of the then-outstanding Class B Subclass Principal Balances  of
the  Class B-2, Class B-3 and  Class B-4 Certificates by the  sum of the Class A
Principal Balance,  the Class  M Principal  Balance and  the Class  B  Principal
Balance.
 
    The  "Original Class B-2 Subordination Level"  is the percentage obtained by
dividing the sum of the initial Class B Subclass Principal Balances of the Class
B-3 and Class B-4 Certificates by  the Cut-Off Date Aggregate Principal  Balance
of the Mortgage Loans. The Original Class B-2 Subordination Level is expected to
be  approximately 2.75%.  The "Current  Class B-2  Subordination Level"  for any
Distribution Date  is  the  percentage  obtained by  dividing  the  sum  of  the
then-outstanding  Class B Subclass Principal Balances of the Class B-3 and Class
B-4 Certificates  by the  sum of  the Class  A Principal  Balance, the  Class  M
Principal Balance and the Class B Principal Balance.
 
  ALLOCATION OF AMOUNT TO BE DISTRIBUTED TO THE CLASS A AND CLASS M CERTIFICATES
 
    On  each Distribution Date occurring prior to the Cross-Over Date, an amount
equal to the Accrual  Distribution Amount will  be allocated sequentially  among
and  distributed in reduction of the principal balances of the Class A-11, Class
A-12 and Class A-13 Certificates, until the Class A Subclass Principal  Balances
thereof have been reduced to zero.
 
    On  each Distribution Date occurring prior to the Cross-Over Date, a portion
of the  remaining  Class A  Principal  Distribution Amount  (after  the  Accrual
Distribution  Amount has  been distributed),  calculated by  multiplying (x) the
fraction equal to $1,000 (I.E., the aggregate initial Class A Subclass Principal
Balance of the Class A-14 Certificates) divided by the initial Class A Principal
Balance  (which  fraction,  expressed  as  a  percentage,  is  expected  to   be
approximately 0.000229%) by (y) the Class A Principal Distribution Amount (other
than  the Accrual Distribution Amount), will  be distributed in reduction of the
Class A Subclass Principal Balance of the Class A-14 Certificates. The remainder
of  the  Class  A  Principal   Distribution  Amount  (other  than  the   Accrual
Distribution Amount) on each Distribution Date occurring prior to the Cross-Over
Date  will  be allocated  among and  distributed in  reduction of  the principal
balances of the Subclasses of Class A Certificates as follows:
 
        FIRST, to  the  Class  A-R  Certificate,  until  the  Class  A  Subclass
    Principal Balance thereof has been reduced to zero;
 
        SECOND,   concurrently,  approximately  93.252043%   to  the  Class  A-1
    Certificates and  approximately 6.747957%  to  the Class  A-4  Certificates,
    until  the Class A Subclass Principal  Balance of the Class A-1 Certificates
    has been reduced to zero;
 
        THIRD, to  the  Class  A-2  Certificates, until  the  Class  A  Subclass
    Principal Balance thereof has been reduced to zero;
 
        FOURTH,   concurrently,  approximately  70.141603%   to  the  Class  A-3
    Certificates and  approximately 29.858397%  to the  Class A-4  Certificates,
    until  the Class A Subclass Principal  Balances thereof have been reduced to
    zero;
 
        FIFTH, sequentially, to the Class A-5,  Class A-6, Class A-7, Class  A-8
    and  Class A-9 Certificates,  until the Class  A Subclass Principal Balances
    thereof have been reduced to zero;
 
        SIXTH, sequentially,  to  the Class  A-11,  Class A-12  and  Class  A-13
    Certificates,  until the  Class A  Subclass Principal  Balances thereof have
    been reduced to zero;  and vSEVENTH, to the  Class A-10 Certificates,  until
    the Class A Subclass Principal Balance thereof has been reduced to zero.
 
                                      S-30
<PAGE>
    On  each Distribution  Date occurring on  or after the  Cross-Over Date, the
Class A Principal Distribution Amount  will be distributed among the  Subclasses
of Class A Certificates pro rata in accordance with their respective outstanding
Class A Subclass Principal Balances.
 
    Amounts  distributed on  each Distribution  Date to  the holders  of Class A
Certificates in  reduction of  principal  balance will  be allocated  among  the
holders  of Class A  Certificates of each  Subclass pro rata  in accordance with
their respective Percentage Interests.
 
    Amounts distributed  on any  Distribution Date  to the  holders of  Class  M
Certificates  in  reduction of  principal balance  will  be allocated  among the
holders of Class  M Certificates pro  rata in accordance  with their  respective
Percentage Interests.
 
ADDITIONAL RIGHTS OF THE CLASS A-R CERTIFICATEHOLDER
 
    The  Class A-R Certificate will remain outstanding  for as long as the Trust
Estate shall exist,  whether or  not it  is receiving  current distributions  of
principal  or interest. The holder of the Class A-R Certificate will be entitled
to receive the proceeds of the remaining assets of the Trust Estate, if any,  on
the   final  Distribution  Date  for  the  Series  1992-14  Certificates,  after
distributions in  respect of  any  accrued but  unpaid  interest on  the  Series
1992-14  Certificates and after distributions  in reduction of principal balance
have reduced the principal balances of the Series 1992-14 Certificates to  zero.
It  is not  anticipated that  there will  be any  assets remaining  in the Trust
Estate on the final  Distribution Date following  the distributions of  interest
and in reduction of principal balance made on the Series 1992-14 Certificates on
such date.
 
    In  addition,  the  Class A-R  Certificateholder  will be  entitled  on each
Distribution Date to receive  any Pool Distribution  Amount remaining after  all
distributions pursuant to the Pool Distribution Amount Allocation have been made
and  any  Net Foreclosure  Profits after  the Servicer  has been  reimbursed for
unpaid Servicing  Fees. See  "Servicing of  the Mortgage  Loans--Fixed  Retained
Yield,  Servicing Compensation and Payment of  Expenses" in the Prospectus. "Net
Foreclosure Profits" means, with respect  to any Distribution Date, the  excess,
if  any, of (i) the aggregate profits  on Liquidated Loans in the related period
with respect  to which  net  Liquidation Proceeds  exceed the  unpaid  principal
balance thereof plus accrued interest thereon at the Mortgage Interest Rate over
(ii)  the aggregate  realized losses on  Liquidated Loans in  the related period
with respect  to  which  net  Liquidation Proceeds  are  less  than  the  unpaid
principal balance thereof plus accrued interest thereon at the Mortgage Interest
Rate.  It is not anticipated that there will be any such Net Foreclosure Profits
or such undistributed Pool Distribution Amounts.
 
PERIODIC ADVANCES
 
    If, on any Determination Date, payments of principal and interest due on any
Mortgage Loan  in  the Trust  Estate  on the  related  Due Date  have  not  been
received,  the Servicer will  be obligated to  advance on or  before the related
Distribution Date for the benefit of holders of the Series 1992-14  Certificates
an amount in cash equal to all delinquent payments of principal and interest due
on  each  Mortgage Loan  in  the Trust  Estate  (with interest  adjusted  to the
applicable Net Mortgage Interest Rate) not previously advanced, but only to  the
extent  that the Servicer believes  that such amounts will  be recoverable by it
from liquidation proceeds or other recoveries in respect of the related Mortgage
Loan.
 
    The Pooling and Servicing  Agreement provides that any  advance of the  kind
described  in the preceding paragraph  may be reimbursed to  the Servicer at any
time from funds available in the Certificate Account to the extent that (i) such
funds represent receipts on, or  liquidation, insurance, purchase or  repurchase
proceeds  in respect of, the Mortgage Loans to which the advance relates or (ii)
the Servicer has determined in good faith that it will be unable to recover such
advance from funds of the type referred to in clause (i) above.
 
RESTRICTIONS ON TRANSFER OF THE CLASS A-R AND CLASS M CERTIFICATES
 
    The Class A-R Certificate will be  subject to the following restrictions  on
transfer,  and the Class  A-R Certificate will contain  a legend describing such
restrictions.
 
                                      S-31
<PAGE>
    The Technical  and  Miscellaneous Revenue  Act  of 1988  amended  the  REMIC
provisions  of the Code  to impose a  tax on transfers  of residual interests to
Disqualified Organizations (as  defined in the  Prospectus). These changes  will
apply  to transferors  of the Class  A-R Certificate  as well as  holders of the
Class A-R  Certificate  that  are  Pass-Through  Entities  (as  defined  in  the
Prospectus).  The Pooling and Servicing Agreement  will provide that no legal or
beneficial interest  in the  Class  A-R Certificate  may  be transferred  to  or
registered  in the name of any person unless (i) the proposed purchaser provides
to the  Trustee  an  affidavit to  the  effect  that, among  other  items,  such
transferee  is not a Disqualified Organization,  is not purchasing the Class A-R
Certificate as an  agent for  a Disqualified  Organization (I.E.,  as a  broker,
nominee,  or  other  middleman thereof)  and  is  not an  entity  (a "Book-Entry
Nominee") that  holds REMIC  residual securities  as nominee  to facilitate  the
clearance  and  settlement  of  such  securities  through  electronic book-entry
changes in  accounts  of participating  organizations  and (ii)  the  transferor
states  in writing  to the  Trustee that  it has  no actual  knowledge that such
affidavit is false. Further,  such affidavit requires  the transferee to  affirm
that  it understands that it must take  into account the taxable income relating
to the Class A-R Certificate, that it has no intention to impede the  assessment
or collection of any federal, state or local income taxes legally required to be
paid with respect to the Class A-R Certificate and that it will not transfer the
Class  A-R Certificate to any person or entity that it has reason to believe has
the intention to impede the assessment or collection of such taxes.
 
    In  addition,  the  Class  A-R  Certificate  may  not  be  purchased  by  or
transferred  to any person that  is not a "U.S.  Person," unless (i) such person
holds the Class A-R  Certificate in connection  with the conduct  of a trade  or
business  within the United States and  furnishes the transferor and the Trustee
with an effective  Internal Revenue  Service Form  4224 or  (ii) the  transferee
delivers  to both  the transferor  and the  Trustee an  opinion of  a nationally
recognized tax counsel to  the effect that such  transfer is in accordance  with
the requirements of the Code and the regulations promulgated thereunder and that
such  transfer of the Class A-R Certificate  will not be disregarded for federal
income tax purposes. The term "U.S. Person"  means a citizen or resident of  the
United  States, a corporation, partnership or  other entity created or organized
in or under the laws of the United States or any political subdivision  thereof,
or  an estate or trust that is subject  to U.S. federal income tax regardless of
the source of its income.
 
    The Pooling  and Servicing  Agreement  will provide  that any  attempted  or
purported  transfer in violation of these transfer restrictions will be null and
void and will  vest no  rights in any  purported transferee.  Any transferor  or
agent  to whom the Trustee provides information as to any applicable tax imposed
on such transferor or  agent may be  required to bear the  cost of computing  or
providing such information. See "Certain Federal Income Tax
Consequences--Federal  Income Tax Consequences  for REMIC Certificates--Taxation
of Residual Certificates--Restrictions on Transfer of the Residual Certificates:

    The Class A-R Certificate may not be purchased by or transferred to an ERISA
Plan. Because  the  Class  M  Certificates  are  subordinated  to  the  Class  A
Certificates, the Class M Certificates may not be purchased by or transferred to
an  ERISA Plan except  upon the delivery  of an opinion  of counsel as described
herein under "ERISA  Considerations." See "ERISA  Considerations" herein and  in
the Prospectus.

Agreement--Trustee" herein.
 
SUBORDINATION OF CLASS M AND CLASS B CERTIFICATES
 
    The  rights  of  the  holders  of  the  Class  M  Certificates  to   receive
distributions  with respect to  the Mortgage Loans  in the Trust  Estate will be
subordinated to such rights of the holders  of the Class A Certificates and  the
rights  of the holders of the Class B Certificates to receive distributions with
respect to the Mortgage Loans in the  Trust Estate will be subordinated to  such
rights of the holders of the Class A and Class M Certificates, all to the extent
described  below. This  subordination is intended  to enhance  the likelihood of
timely receipt by the holders of the Class A Certificates (to the extent of  the
subordination  of the Class M  and Class B Certificates)  and the holders of the
Class M  Certificates  (to  the extent  of  the  subordination of  the  Class  B
Certificates) of the full amount of their scheduled monthly payments of interest
and  principal and  to afford the  holders of  the Class A  Certificates (to the
extent of the subordination  of the Class  M and Class  B Certificates) and  the
holders  of the Class M Certificates (to  the extent of the subordination of the
Class  B  Certificates)  protection  against  Realized  Losses,  as  more  fully
described  below. If Realized Losses exceed  the credit support provided through
subordination to  the Class  A and  Class M  Certificates or  if Excess  Special
Hazard  Losses, Excess Fraud Losses or Excess  Bankruptcy Losses occur, all or a
portion of such losses will be borne by the Class A and Class M Certificates.
 
    The protection afforded to the holders  of Class A Certificates by means  of
the subordination feature will be accomplished by the preferential right of such
holders  to receive, prior to any distribution being made on a Distribution Date
in respect of the Class M and Class B Certificates, the amounts of principal and
interest due the Class A Certificateholders on each Distribution Date out of the
Pool Distribution Amount  with respect to  such date and,  if necessary, by  the
right of such holders to receive future distributions on the Mortgage Loans that
would  otherwise  have  been payable  to  the holders  of  Class M  and  Class B
Certificates. The application  of this  subordination to  cover Realized  Losses
experienced  in periods  prior to  the periods  in which  a Subclass  of Class A
Certificates is entitled to distributions in reduction of principal balance will
decrease the protection provided by the subordination to any such Subclass.
 
    The protection afforded to the holders  of Class M Certificates by means  of
the subordination feature will be accomplished by the preferential right of such
holders  to receive, prior to any distribution being made on a Distribution Date
in respect of the  Class B Certificates, the  amounts of principal and  interest
due  the  Class M  Certificateholders on  each Distribution  Date from  the Pool
Distribution Amount with respect  to such date (after  all required payments  on
the Class A Certificates have been made) and, if necessary, by the right of such
holders  to  receive  future  distributions on  the  Mortgage  Loans  that would
otherwise have been payable to the holders of the Class B Certificates.
 
                                      S-33
<PAGE>
    The Class B Certificates will be entitled, on each Distribution Date, to the
remaining portion, if  any, of  the applicable Pool  Distribution Amount,  after
payment  of the Class A Distribution Amount  and the Class M Distribution Amount
for such date. Amounts so distributed to Class B Certificateholders will not  be
available  to cover  delinquencies or Realized  Losses in  respect of subsequent
Distribution Dates.
 
  ALLOCATION OF LOSSES
 
    Realized Losses  (other  than Excess  Special  Hazard Losses,  Excess  Fraud
Losses  or Excess Bankruptcy Losses) will not be allocated to the holders of the
Class A Certificates until the date on which the amount of principal payments on
the Mortgage Loans  to which the  holders of the  Subordinated Certificates  are
entitled has been reduced to zero as a result of the allocation of losses to the
Subordinated  Certificates, I.E., the date  on which the Subordinated Percentage
has been  reduced to  zero (the  "Cross-Over Date").  Prior to  such time,  such
Realized   Losses  will  be  allocated  first  to  the  subclasses  of  Class  B
Certificates sequentially in their  reverse numerical order,  until the Class  B
Subclass Principal Balances of each such subclass have been reduced to zero, and
then  to the Class M  Certificates until the Class  M Principal Balance has been
reduced to zero.
 
    The allocation of  the principal portion  of a Realized  Loss (other than  a
Debt  Service Reduction, Excess Special Hazard Loss, Excess Fraud Loss or Excess
Bankruptcy Loss)  will  be effected  through  the adjustment  of  the  principal
balance  of the  most subordinate  Class then-outstanding  in such  amount as is
necessary to cause the sum of the Class A Subclass Principal Balances, the Class
M Principal Balance  and the Class  B Subclass Principal  Balances to equal  the
Adjusted Pool Amount.
 
    Allocations  to the Class M Certificates or  Class B Certificates of (i) the
principal portion  of Debt  Service  Reductions, (ii)  the interest  portion  of
Realized  Losses (other than  Excess Special Hazard  Losses, Excess Fraud Losses
and Excess Bankruptcy Losses) and  (iii) any interest shortfalls resulting  from
delinquencies  for which  the Servicer  does not  advance, will  result from the
priority of distributions first  to the Class A  Certificateholders and then  to
the  Class M  Certificateholders of  the Pool  Distribution Amount  as described
above under "--Distributions."
 
    The principal  portion  of any  Realized  Loss  occurring on  or  after  the
Cross-Over  Date will be  allocated among the outstanding  Subclasses of Class A
Certificates pro rata in accordance with their then outstanding Class A Subclass
Principal Balances or, in  the case of the  Accrual Certificates, their  initial
Class  A Subclass Principal Balance, if lower, and among the outstanding Class A
Certificates within each Subclass pro  rata in accordance with their  respective
Percentage Interests.
 
    Any  Excess Special Hazard Losses, Excess  Fraud Losses or Excess Bankruptcy
Losses will be  allocated on a  pro rata basis  among the Class  A, Class M  and
Class  B Certificates (any such losses so  allocated to the Class A Certificates
will be allocated among the outstanding  Subclasses of Class A Certificates  pro
rata  in  accordance  with their  then  outstanding Class  A  Subclass Principal
Balances or, in  the case  of the Accrual  Certificates, their  initial Class  A
Subclass  Principal Balance, if  lower,with respect to  the principal portion of
such losses and their Class A Subclass Interest Accrual Amounts with respect  to
the  interest  portion  of  such  losses,  and  among  the  outstanding  Class A
Certificates within each Subclass pro  rata in accordance with their  respective
Percentage  Interests). An allocation of a loss  on a "pro rata basis" among two
or more Classes of Certificates means an allocation on a pro rata basis to  each
such  Class of  Certificates on  the basis  of their  then outstanding principal
balances in the case of the principal portion of a loss or based on the  accrued
interest thereon in the case of an interest portion of a loss.
 
    The  interest portion of  Excess Special Hazard  Losses, Excess Fraud Losses
and Excess Bankruptcy Losses will be allocated by reducing the applicable  Class
B  Subclass Interest Accrual Amount, Class M  Interest Accrual Amount or Class A
Interest Accrual Amount.
 
    As described above, the Pool  Distribution Amount for any Distribution  Date
will  include  current  receipts  (other than  certain  unscheduled  payments in
respect of principal) from  the Mortgage Loans otherwise  payable to holders  of
the  Class M and  Class B Certificates.  If the Pool  Distribution Amount is not
sufficient to cover the amount of principal payable to the holders of the  Class
A Certificates on a
 
                                      S-34
<PAGE>
particular  Distribution Date (other  than any portion  thereof representing the
difference between the Class A Percentage of the Scheduled Principal Balances of
Liquidated Loans and the  Class A Prepayment Percentage  of such amounts),  then
the  percentage of principal payments on the Mortgage Loans to which the holders
of the Class A Certificates will be  entitled (I.E., the Class A Percentage)  on
and  after the next Distribution Date will be proportionately increased, thereby
reducing, as a relative matter, the respective interest of the Class M and Class
B Certificates in  future payments  of principal on  the Mortgage  Loans in  the
Trust  Estate.  Such a  shortfall could  occur, for  example, if  a considerable
number of Mortgage Loans were to become Liquidated Loans in a particular month.
 
    Special Hazard Losses will be allocated solely to the Class B  Certificates,
or  following the reduction of the Class  B Principal Balance to zero, solely to
the Class M Certificates, but only prior to the Special Hazard Termination Date.
The "Special Hazard Termination Date" will  be the date on which Special  Hazard
Losses  exceed the  Special Hazard Loss  Amount (or, if  earlier, the Cross-Over
Date). Upon initial issuance  of the Series  1992-14 Certificates, the  "Special
Hazard  Loss Amount" with  respect thereto will be  equal to approximately 1.28%
(approximately $6,097,342) of  the Cut-Off Date  Aggregate Principal Balance  of
the  Mortgage Loans. As of any Distribution Date, the Special Hazard Loss Amount
will equal  the initial  Special Hazard  Loss Amount  less the  sum of  (A)  any
Special  Hazard Losses allocated solely  to the Class B  or Class M Certificates
and (B) the Adjustment  Amount. The "Adjustment Amount"  on each anniversary  of
the  Cut-Off Date  will be  equal to the  amount, if  any, by  which the Special
Hazard Amount, without giving effect to  the deduction of the Adjustment  Amount
for  such anniversary,  exceeds the  greater of (i)  1.00% (or,  if greater than
1.00%, the highest  percentage of  Mortgage Loans  by principal  balance in  any
California  zip code) times the aggregate  principal balance of all the Mortgage
Loans on such  anniversary and (ii)  twice the principal  balance of the  single
Mortgage  Loan having  the largest principal  balance. Special  Hazard Losses in
excess of the Special Hazard Loss Amount are "Excess Special Hazard Losses".
 
    Fraud Losses  will be  allocated  solely to  the  Class B  Certificates,  or
following  the reduction of the Class B Principal Balance to zero, solely to the
Class M Certificates but only prior to the Fraud Coverage Termination Date.  The
"Fraud  Coverage Termination Date" will be the date on which Fraud Losses exceed
the Fraud  Loss Amount  (or,  if earlier,  the  Cross-Over Date).  Upon  initial
issuance  of  the  Series 1992-14  Certificates,  the "Fraud  Loss  Amount" with
respect thereto will be equal to approximately 2.00% (approximately  $9,527,097)
of  the Cut-Off Date Aggregate Principal Balance  of the Mortgage Loans. On each
Distribution Date thereafter, the Fraud Loss Amount will equal (X) prior to  the
first  anniversary of the Cut-Off Date an amount equal to the initial Fraud Loss
Amount minus the aggregate amount of Fraud Losses allocated solely to the  Class
B or the Class M Certificates up to the related Determination Date, and (Y) from
the  first through fifth anniversary of the Cut-Off Date, an amount equal to (1)
the lesser of (a) the Fraud Loss Amount as of the most recent anniversary of the
Cut-Off Date and  (b) 1.00% of  the aggregate  principal balance of  all of  the
Mortgage  Loans as of the most recent  anniversary of the Cut-Off Date minus (2)
the  aggregate  amounts  allocated  solely  to  the  Class  B  or  the  Class  M
Certificates  with respect to Fraud Losses  since the most recent anniversary of
the Cut-Off  Date  up  to  the  related  Determination  Date.  After  the  fifth
anniversary  of  the  Cut-Off Date,  the  Fraud  Loss Amount  will  be  zero and
thereafter any Fraud Losses will be shared  pro rata among the Class A, Class  M
and  Class B Certificates. Fraud  Losses in excess of  the Fraud Loss Amount are
"Excess Fraud Losses."
 
    Bankruptcy Losses will be allocated solely  to the Class B Certificates,  or
following  the reduction of the  Class B Principal Balance  to zero, the Class M
Certificates but only  prior to  the Bankruptcy Coverage  Termination Date.  The
"Bankruptcy  Coverage Termination  Date" will  be the  date on  which Bankruptcy
Losses exceed the Bankruptcy Loss Amount (or, if earlier, the Cross-Over  Date).
Upon  initial issuance of the Series  1992-14 Certificates, the "Bankruptcy Loss
Amount" with respect thereto will be equal to approximately 0.11% (approximately
$504,237) of the Cut-Off Date Aggregate Principal Balance of the Mortgage Loans.
As of any Distribution Date prior to the first anniversary of the Cut-Off  Date,
the  Bankruptcy Loss Amount will equal  the initial Bankruptcy Loss Amount minus
the aggregate amount of  Bankruptcy Losses allocated solely  to the Class B  and
Class   M  Certificates  up  to  the  related  Determination  Date.  As  of  any
Distribution Date on  or after the  first anniversary of  the Cut-Off Date,  the
Bankruptcy
 
                                      S-35
<PAGE>
Loss  Amount  will equal  the  excess, if  any,  of (1)  the  lesser of  (a) the
Bankruptcy Loss Amount  as of the  business day next  preceding the most  recent
anniversary  of the Cut-Off  Date and (b)  an amount calculated  pursuant to the
terms of the Pooling  and Servicing Agreement, which  amount as calculated  will
provide  for a reduction in  the Bankruptcy Loss Amount,  over (2) the aggregate
amount of Bankruptcy  Losses allocated  solely to  the Class  B Certificates  or
Class  M Certificates since such anniversary. The Bankruptcy Loss Amount and the
related coverage levels described above may be reduced or modified upon  written
confirmation  from S&P  and Fitch that  such reduction or  modification will not
adversely affect the then-current  ratings assigned to the  Class A and Class  M
Certificates  by S&P and  Fitch. Such a reduction  or modification may adversely
affect the coverage provided by subordination with respect to Bankruptcy Losses.
Bankruptcy Losses in excess of the Bankruptcy Loss Amount are "Excess Bankruptcy
Losses."
 
    Notwithstanding the foregoing, the provisions relating to subordination will
not be applicable in connection with a  Bankruptcy Loss so long as the  Servicer
has notified the Trustee in writing that the Servicer is diligently pursuing any
remedies  that may exist  in connection with  the representations and warranties
made regarding the related Mortgage Loan and when (A) the related Mortgage  Loan
is  not in default with regard to  the payments due thereunder or (B) delinquent
payments of  principal and  interest under  the related  Mortgage Loan  and  any
premiums  on any  applicable Standard  Hazard Insurance  Policy and  any related
escrow payments in respect of such Mortgage Loan are being advanced on a current
basis by the Servicer, in either case without giving effect to any Debt  Service
Reduction.
 
    Since  the  initial principal  balance of  the Class  B Certificates  in the
aggregate will be approximately $25,009,867, the risk of Special Hazard  Losses,
Fraud  Losses and Bankruptcy Losses will be borne by the Class B Certificates to
a lesser extent (I.E.,  only up to  the Special Hazard  Loss Amount, Fraud  Loss
Amount and Bankruptcy Loss Amount, respectively) than the risk of other Realized
Losses,  which they  will bear  to the  full extent  of their  initial principal
balance.  See   "The  Trust   Estates--Mortgage  Loans--   Representations   and
Warranties"  and "--Insurance Policies," "Certain  Legal Aspects of the Mortgage
Loans--Environmental   Considerations"   and   "Servicing   of   the    Mortgage
Loans--Enforcement  of Due-on-Sale Clauses;  Realization Upon Defaulted Mortgage
Loans" in the Prospectus.

                      DESCRIPTION OF THE MORTGAGE LOANS(1)
 
    The Mortgage Loans to be included in the Trust Estate will be fixed interest
rate,  conventional,  monthly  pay,  fully  amortizing,  one-  to   four-family,
residential  first mortgage  loans originated  or acquired  by PHMC  for its own
account or  for the  account of  an affiliate  having original  terms to  stated
maturity  of approximately 30 years. The  Mortgage Loans are expected to include
1,811 promissory notes, to have an aggregate unpaid principal balance as of  the
Cut-Off  Date (the "Cut-Off Date  Aggregate Principal Balance") of approximately
$476,354,867, to be secured  by first liens (the  "Mortgages") on one- to  four-
family  residential  properties (the  "Mortgaged  Properties") and  to  have the
additional characteristics described below and in the Prospectus.
 
    No Mortgage  Loan is  a Buy-Down  Loan or  a Subsidy  Loan. See  "The  Trust
Estates--Mortgage  Loans"  in the  Prospectus. No  Mortgage Loan  was originated
pursuant  to  PHMC's  relocation  mortgage  program.  See  "PHMC--Mortgage  Loan
Production Sources" in the Prospectus.
 
    Each  of the Mortgage Loans is subject to a due-on-sale clause. See "Certain
Legal Aspects of  the Mortgage Loans--'Due-on-Sale'  Clauses" and "Servicing  of
the   Mortgage  Loans--Enforcement  of  Due-on-Sale  Clauses;  Realization  Upon
Defaulted Mortgage Loans" in the Prospectus.
 
    As of the Cut-Off  Date, each Mortgage  Loan is expected  to have an  unpaid
principal  balance of  not less  than $24,986 or  more than  $1,490,377, and the
average unpaid  principal  balance of  the  Mortgage  Loans is  expected  to  be
approximately  $263,034. The latest stated maturity  date of any of the Mortgage
Loans is expected  to be  May 1,  2022; however, the  actual date  on which  any
Mortgage  Loan is paid in full may be  earlier than the stated maturity date due
to unscheduled  payments of  principal.  Based on  information supplied  by  the
mortgagors  in connection with their loan  applications at origination, 1,699 of
the Mortgaged Properties, which secure approximately 96.16% of the Cut-Off  Date
Aggregate  Principal Balance  of the  Mortgage Loans,  are expected  to be owner
occupied primary residences and  112 of the  Mortgaged Properties, which  secure
approximately  3.84%  of the  Cut-Off Date  Aggregate  Principal Balance  of the
Mortgage Loans,  are expected  to be  non-owner occupied  or second  homes.  See
"PHMC--Mortgage Loan Underwriting" in the Prospectus.
 
- ------------------------
(1) The  descriptions in this Prospectus Supplement  of the Trust Estate and the
    properties securing the Mortgage  Loans to be included  in the Trust  Estate
    are  based upon  the expected characteristics  of the Mortgage  Loans at the
    close of  business  on the  Cut-Off  Date,  as adjusted  for  the  scheduled
    principal   payments  due  on  or  before  such  date.  Notwithstanding  the
    foregoing, any of such Mortgage Loans may be excluded from the Trust  Estate
    (i)  as a result  of principal prepayment thereof  in full or  (ii) if, as a
    result of  delinquencies  or  otherwise, the  Seller  otherwise  deems  such
    exclusion  necessary or desirable. In either event, other Mortgage Loans may
    be included in the  Trust Estate. The Seller  believes that the  information
    set  forth  herein  with  respect to  the  expected  characteristics  of the
    Mortgage Loans on the Cut-Off Date is representative of the  characteristics
    as  of the Cut-Off  Date of the Mortgage  Loans to be  included in the Trust
    Estate as it will be constituted at the time the Series 1992-14 Certificates
    are issued, although the Cut-Off Date Aggregate Principal Balance, the range
    of Mortgage Interest Rates and maturities, and certain other characteristics
    of the Mortgage Loans in the Trust Estate may vary. In the event that any of
    the characteristics  as of  the  Cut-Off Date  of  the Mortgage  Loans  that
    constitute  the Trust Estate on  the date of initial  issuance of the Series
    1992-14 Certificates vary  materially from those  described herein,  revised
    information   regarding  the  Mortgage  Loans  will  be  made  available  to
    purchasers of the Class A Certificates, on or before such issuance date, and
    a Current Report on Form 8-K containing such information will be filed  with
    the Securities and Exchange Commission within 15 days following such date.

As  of the  Cut-Off Date,  the weighted  average Mortgage  Interest Rate  of the
Mortgage Loans  is  expected to  be  approximately  9.038% per  annum.  The  Net
Mortgage  Interest Rate  of each  Mortgage Loan  will be  equal to  the Mortgage
Interest Rate of such Mortgage  Loan minus the Servicing  Fee rate of 0.25%  per
annum.  As of the Cut-Off Date, the  weighted average Net Mortgage Interest Rate
of the Mortgage Loans is expected to be approximately 8.788% per annum.

As  of  the  Cut-Off  Date,  the minimum  and  maximum  Loan-to-Value  Ratios at
origination of  the  Mortgage  Loans  are expected  to  be  15.74%  and  90.00%,
respectively, and the weighted average Loan-to-Value Ratio at origination of the
Mortgage Loans is expected to be approximately 71%. The Loan-to-Value Ratio of a
Mortgage  Loan is calculated using the lesser  of (i) the appraised value of the
related Mortgaged  Property, as  established  by an  appraisal obtained  by  the
originator  from an appraiser at the time of origination and (ii) the sale price
for such property. See "The Trust Estates--Mortgage Loans" in the Prospectus. It
is expected  that  36 of  the  Mortgage  Loans having  Loan-to-Value  Ratios  at
origination  in excess of  80%, representing approximately  1.77% of the Cut-Off
Date Aggregate Principal Balance of the Mortgage Loans, were originated  without
primary  mortgage  insurance.  See  "PHMC--Mortgage  Loan  Underwriting"  in the
Prospectus.

Documentation levels vary depending upon several factors, including loan amount,
Loan-to-Value Ratio and the type and purpose of the Mortgage Loan. Asset, income
and mortgage verifications were obtained for Mortgage Loans processed with "full
documentation." In the case of "preferred processing," neither asset, income nor
mortgage verifications were obtained.  However, for all  of the Mortgage  Loans,
verification of the borrower's employment, a credit report on the borrower and a
property  appraisal were obtained. See "PHMC--Mortgage Loan Underwriting" in the
Prospectus.

In  general,  in the  case of  a  Mortgage Loan  made for  "rate/term" refinance
purposes, substantially  all  of  the proceeds  are  used  to pay  in  full  the
principal balance of a previous mortgage loan of the mortgagor with respect to a
Mortgaged Property and to pay origination and closing costs associated with such
refinancing.  However, in the case of a Mortgage Loan made for "equity take out"
refinance purposes, all or a portion  of the proceeds are generally retained  by
the  mortgagor for uses unrelated to the  Mortgaged Property. The amount of such
proceeds  retained  by  the  mortgagor  may  be  substantial.  See  "The   Trust
Estates--Mortgage   Loans"  and   "PHMC--Mortgage  Loan   Underwriting"  in  the
Prospectus.
 
MANDATORY REPURCHASE OR SUBSTITUTION OF MORTGAGE LOANS
 
    The Seller is required, with respect to Mortgage Loans that are found by the
Trustee to have defective documentation, or  in respect of which the Seller  has
breached  a representation or warranty, either to repurchase such Mortgage Loans
or, if within two years  of the date of initial  issuance of the Series  1992-14
Certificates,  to substitute new  Mortgage Loans therefor.  Any Mortgage Loan so
substituted must, among other things, have an unpaid principal balance equal  to
or  less than the Scheduled Principal Balance  of the Mortgage Loan for which it
is being substituted (after giving effect to the scheduled principal payment due
in the month of substitution on the Mortgage Loan for which a new Mortgage  Loan
is  being  substituted), a  Loan-to-Value Ratio  less  than or  equal to,  and a
Mortgage Interest Rate  no less than,  and no  more than one  percent per  annum
greater  than, that of the Mortgage Loan  for which it is being substituted. Any
such substitution may be made only upon receipt by the Trustee of an opinion  of
counsel   or  other  satisfactory  evidence   that,  among  other  things,  such
substitution will not subject the Trust Estate to tax or cause the Trust  Estate
to  fail to qualify as a REMIC. See "Prepayment and Yield Considerations" herein
and "The  Trust Estates--Mortgage  Loans--Assignment of  Mortgage Loans  to  the
Trustee" in the Prospectus.
 
OPTIONAL REPURCHASE OF DEFAULTED MORTGAGE LOANS
 
    The  Seller may, in  its sole discretion,  repurchase any defaulted Mortgage
Loan from the Trust Estate at a  price equal to the unpaid principal balance  of
such Mortgage Loan, together with accrued interest at
 
                                      S-43
<PAGE>
a  rate equal to the Mortgage Interest Rate through the last day of the month in
which such repurchase occurs.  See "The Trust Estates--Mortgage  Loans--Optional
Repurchases"  in the Prospectus. The Servicer may, in its sole discretion, allow
the assumption  of  a defaulted  Mortgage  Loan  by a  borrower  meeting  PHMC's
underwriting  guidelines or  encourage the  refinancing of  a defaulted Mortgage
Loan. See "Prepayment  and Yield  Considerations" herein and  "Servicing of  the
Mortgage  Loans--Enforcement of Due-on-Sale  Clauses; Realization Upon Defaulted
Mortgage Loans" in the Prospectus.
 
              ORIGINATION, DELINQUENCY AND FORECLOSURE EXPERIENCE
 
LOAN ORIGINATION
 
    During the years ended  December 31, 1990, December  31, 1991 and the  three
months  ended March 31, 1992, PHMC originated  or purchased, for its own account
or for the account of an affiliate, conventional mortgage loans having aggregate
principal  balances   of   approximately  $5,837,566,957,   $9,742,858,764   and
$4,497,908,446, respectively.
 
DELINQUENCY AND FORECLOSURE EXPERIENCE
 
    The  following  tables  set  forth  certain  information  concerning  recent
delinquency, foreclosure and loan loss  experience on the conventional  mortgage
loans included in PHMC's mortgage loan servicing portfolio which were originated
by  PHMC for its own account  or for the account of  an affiliate or acquired by
PHMC for its own account or for the account of an affiliate and underwritten  to
PHMC's  underwriting standards (the "Program Loans"), on the Program Loans which
are fixed interest rate  mortgage loans ("Fixed  Program Loans"), including,  in
both  cases,  mortgage  loans originated  in  connection with  the  purchases of
residences by  relocated employees  ("Relocation Mortgage  Loans"), and  on  the
Fixed Program Loans, other than Relocation Mortgage Loans ("Fixed Non-relocation
Program  Loans"). See "Description of the  Mortgage Loans" herein and "The Trust
Estates--Mortgage Loans" and  "PHMC-- General,"  "--Mortgage Loan  Underwriting"
and  "--Servicing" in the Prospectus. The delinquency, foreclosure and loan loss
experience represents the recent experience of PHMC and The Prudential  Mortgage
Capital  Company, Inc.,  an affiliate of  PHMC which serviced  the Program Loans
prior to  June  30,  1989. There  can  be  no assurance  that  the  delinquency,
foreclosure  and loan  loss experience  set forth  with respect  to PHMC's total
servicing portfolio of Program Loans,  which includes both fixed and  adjustable
interest  rate mortgage loans  and loans having  a variety of  original terms to
stated maturity including Relocation Mortgage Loans and non-relocation  mortgage
loans,  and  PHMC's  servicing  portfolios  of  Fixed  Program  Loans  or  Fixed
Non-relocation Program Loans, each of which  includes loans having a variety  of
payment  characteristics,  such as  Subsidy  Loans, Buy-Down  Loans  and Balloon
Loans, will  be representative  of  the results  that  may be  experienced  with
respect to the Mortgage Loans included in the Trust Estate.
 
    Historically,  Relocation  Mortgage  Loans, which  constitute  a significant
percentage of the Mortgage Loans currently serviced by PHMC, have experienced  a
significantly  lower  rate of  delinquency and  foreclosure than  other mortgage
loans included in the portfolios of total Program Loans and Fixed Program Loans.
There can  be no  assurance that  the future  experience on  the Mortgage  Loans
contained  in the Trust  Estate, all of  which are fixed  interest rate mortgage
loans having original terms to stated  maturity of 30 years, will be  comparable
to  that  of the  total  Program Loans,  the Fixed  Program  Loans or  the Fixed
Non-relocation Program Loans.

- --------------------------
(1) The indicated periods of  delinquency are based on  the number of days  past

    these purposes until one month has passed since its contractual due date.  A

    proceedings have commenced.
 
(2) Includes loans in the applicable portfolio for which foreclosure proceedings
    had been instituted or with respect  to which the related property had  been
    acquired as of the dates indicated.
 
(3) Foreclosures  as a percentage of total  loans in the applicable portfolio at

(4) Does not  include gain  or loss  with  respect to  loans in  the  applicable
    portfolio  for  which foreclosure  proceedings had  been instituted  but not
    completed as of  the dates indicated,  or for which  the related  properties
    have been acquired in foreclosure proceedings but not yet sold.
 
(5) Net  gain (loss) as a percentage of  total loans in the applicable portfolio
    at the end of each period.
 
    The likelihood that a mortgagor will become delinquent in the payment of his
or her mortgage loan, the rate of any subsequent foreclosures, and the  severity
of any loan loss experience, may be affected by a number of factors related to a
borrower's  personal circumstances, including, but  not limited to, unemployment
or change  in  employment  (or  in  the  case  of  self-employed  mortgagors  or
mortgagors  relying  on  commission  income,  fluctuations  in  income), marital
separation and  the mortgagor's  equity in  the related  mortgaged property.  In
addition,  delinquency, foreclosure and loan loss experience may be sensitive to
adverse economic  conditions,  either  nationally  or  regionally,  may  exhibit
seasonal  variations and may  be influenced by  the level of  interest rates and
servicing  decisions  on  the  applicable  mortgage  loans.  Regional   economic
conditions  (including  declining real  estate  values) may  particularly affect
delinquency, foreclosure  and loan  loss  experience on  mortgage loans  to  the
extent  that mortgaged properties are  concentrated in certain geographic areas.
The Seller believes that  the changes in the  delinquency, foreclosure and  loan
loss experience of PHMC's respective servicing portfolios during the periods set
forth  in the  preceding tables  may be  attributable to  factors such  as those
described above,
 
                                      S-47
<PAGE>
although the Seller is  unable to assess  to what extent  these changes are  the
result  of any particular  factor or a combination  of factors. The delinquency,
foreclosure and loan  loss experience  on the  Mortgage Loans  contained in  the
Trust  Estate  may be  particularly affected  to the  extent that  the Mortgaged
Properties  are  concentrated  in   areas  which  experience  adverse   economic
conditions  or declining  real estate values.  See "Description  of the Mortgage
Loans."
 
                      PREPAYMENT AND YIELD CONSIDERATIONS
 
    The rate  of distributions  in reduction  of the  principal balance  of  any
Subclass of the Class A Certificates and the Class M Certificates, the aggregate
amount  of distributions  on any  Subclass of the  Class A  Certificates and the
Class M Certificates and the  yield to maturity of any  Subclass of the Class  A
Certificates  and the  Class M Certificates  purchased at a  discount or premium
will be directly related to  the rate of payments  of principal on the  Mortgage
Loans  in  the Trust  Estate and  the  amount and  timing of  mortgagor defaults
resulting in Realized  Losses. The rate  of principal payments  on the  Mortgage
Loans  will in turn  be affected by  the amortization schedules  of the Mortgage
Loans, the  rate of  principal prepayments  (including partial  prepayments  and
those  resulting  from  refinancing)  thereon  by  mortgagors,  liquidations  of
defaulted Mortgage  Loans, repurchases  by the  Seller of  Mortgage Loans  as  a
result of defective documentation or breaches of representations and warranties,
optional  repurchase  by the  Seller of  defaulted  Mortgage Loans  and optional
purchase by the Servicer  of all of  the Mortgage Loans  in connection with  the
termination   of   the  Trust   Estate.   See  "Description   of   the  Mortgage
Loans--Optional  Repurchase  of  Defaulted  Mortgage  Loans"  and  "Pooling  and
Servicing    Agreement--Optional    Termination"   herein    and    "The   Trust
Estates--Mortgage  Loans--Assignment  of   Mortgage  Loans   to  the   Trustee,"
"--Optional  Repurchases" and "The Pooling and Servicing Agreement--Termination;
Purchase of  Mortgage Loans"  in  the Prospectus.  Mortgagors are  permitted  to
prepay  the Mortgage Loans, in whole or in part, at any time without penalty. As
described  under   "Description   of  the   Certificates--Principal   (Including
Prepayments)"   herein,  all  or  a  disproportionate  percentage  of  principal
prepayments on the  Mortgage Loans  (including liquidations  and repurchases  of
Mortgage  Loans) will be distributed to the holders of Class A Certificates then
entitled to  distributions  in  respect  of  principal  during  the  nine  years
beginning  on the first  Distribution Date. Prepayments  (which, as used herein,
include all unscheduled payments of principal, including payments as the  result
of  liquidations, purchases and repurchases) of  the Mortgage Loans in the Trust
Estate will  result  in distributions  to  Certificateholders then  entitled  to
distributions  in  respect  of principal  of  amounts which  would  otherwise be
distributed over the remaining terms of  such Mortgage Loans. Since the rate  of
prepayment  on the Mortgage Loans will depend  on future events and a variety of
factors (as described more fully below  and in the Prospectus under  "Prepayment
and  Yield Considerations"), no  assurance can be  given as to  such rate or the
rate of principal payments on  any Subclass of the  Class A Certificates or  the
Class M Certificates or the aggregate amount of distributions on any Subclass of
Class A Certificates or the Class M Certificates.
 
    The  rate of payments (including prepayments)  on pools of mortgage loans is
influenced by a variety  of economic, geographic, social  and other factors.  If
prevailing  rates  for  similar  mortgage  loans  fall  significantly  below the
Mortgage Interest Rates  on the  Mortgage Loans,  the rate  of prepayment  would
generally  be expected  to increase.  Conversely, if  interest rates  on similar
mortgage loans  rise significantly  above  the Mortgage  Interest Rates  on  the
Mortgage Loans, the rate of prepayment would generally be expected to decrease.
 
    Other  factors  affecting prepayment  of mortgage  loans include  changes in
mortgagors' housing  needs,  job transfers,  unemployment  or, in  the  case  of
self-employed mortgagors or mortgagors relying on commission income, substantial
fluctuations  in income, significant declines in  real estate values and adverse
economic  conditions  either  generally  or  in  particular  geographic   areas,
mortgagors'  equity  in the  Mortgaged  Properties and  servicing  decisions. In
addition, all  of the  Mortgage  Loans contain  due-on-sale clauses  which  will
generally  be  exercised  upon the  sale  of the  related  Mortgaged Properties.
Consequently, acceleration of  mortgage payments as  a result of  any such  sale
will  affect the level of prepayments on the Mortgage Loans. The extent to which
defaulted Mortgage Loans  are assumed  by transferees of  the related  Mortgaged
Properties  will  also  affect  the  rate of  principal  payments.  The  rate of
 
                                      S-48
<PAGE>
prepayment and, therefore,  the yield to  maturity of  the Class A  and Class  M
Certificates  will be affected by  the extent to which  (i) the Seller elects to
repurchase, rather than substitute  for, Mortgage Loans which  are found by  the
Trustee  to have defective documentation or with respect to which the Seller has
breached a representation or warranty or  (ii) the Servicer elects to  encourage
the  refinancing  of  any  defaulted  Mortgage Loan  rather  than  to  permit an
assumption  thereof  by   a  mortgagor  meeting   the  Servicer's   underwriting
guidelines.  See "Servicing  of the  Mortgage Loans--Enforcement  of Due-on-Sale
Clauses; Realization Upon Defaulted Mortgage Loans" in the Prospectus. There can
be no certainty as to the rate  of prepayments on the Mortgage Loans during  any
period  or over the life of the Series 1992-14 Certificates. See "Prepayment and
Yield Considerations" in the Prospectus.
 
    The timing of changes in  the rate of prepayment  on the Mortgage Loans  may
significantly affect the actual yield to maturity experienced by an investor who
purchases  a Class A or Class  M Certificate at a price  other than par, even if
the average rate of principal payments experienced over time is consistent  with
such  investor's expectation. In general, the  earlier a prepayment of principal
on the underlying  Mortgage Loans,  the greater  the effect  on such  investor's
yield to maturity. As a result, the effect on such investor's yield 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 Class A and
Class M Certificates would  not be fully offset  by a subsequent like  reduction
(or increase) in the rate of principal payments.
 
    The  yield to maturity  on the Class  M Certificates will  be more sensitive
than the Class A Certificates  to losses due to  defaults on the Mortgage  Loans
(and the timing thereof), to the extent not covered by the Class B Certificates,
because  the  entire amount  of such  losses will  be allocable  to the  Class M
Certificates prior to  the Class  A Certificates, except  as otherwise  provided
herein.  To  the  extent  not covered  by  Periodic  Advances,  delinquencies on
Mortgage Loans  may  also have  a  relatively greater  effect  on the  yield  to
investors  in  the  Class  M Certificates.  Amounts  otherwise  distributable to
holders of  the Class  M Certificates  will  be made  available to  protect  the
holders  of the Class A Certificates  against interruptions in distributions due
to certain  mortgagor  delinquencies.  Such delinquencies,  to  the  extent  not
covered  by the Class B Certificates, even if subsequently cured, may affect the
timing of the receipt of distributions  by the holders of Class M  Certificates,
because  the entire amount of those delinquencies  would be borne by the Class M
Certificates prior to the Class A Certificates.
 
    No representation  is made  as to  the  rate of  principal payments  on  the
Mortgage  Loans  or as  to the  yield to  maturity  of any  Subclass of  Class A
Certificates or  the Class  M Certificates.  An  investor is  urged to  make  an
investment  decision with respect to any Subclass of Class A Certificates or the
Class M Certificates based on the anticipated yield to maturity to such Subclass
of Class A Certificates or the Class M Certificates resulting from its  purchase
price  and such  investor's own  determination as  to anticipated  Mortgage Loan
prepayment rates under a variety of scenarios. The extent to which any  Subclass
of  Class A Certificates or the Class M Certificates are purchased at a discount
or a premium, the  degree to which  the timing of payments  on such Subclass  or
Class  is sensitive to prepayments will determine  the extent to which the yield
to maturity of such Subclass  or Class may vary  from the anticipated yield.  An
investor  should carefully consider the associated risks, including, in the case
of any Class A or Class M Certificates purchased at a discount, the risk that  a
slower  than anticipated rate of principal  payments on the Mortgage Loans could
result in an actual yield  to such investor that  is lower than the  anticipated
yield  and, in the  case of any Class  A or Class M  Certificates purchased at a
premium, the risk  that a  faster than  anticipated rate  of principal  payments
could  result  in  an actual  yield  to such  investor  that is  lower  than the
anticipated yield.
 
    An investor should consider the risk that rapid rates of prepayments on  the
Mortgage Loans, and therefore of amounts distributable in reduction of principal
balance of the Class A or Class M Certificates, may coincide with periods of low
prevailing  interest rates. During such periods, the effective interest rates on
securities in which an  investor may choose to  reinvest amounts distributed  in
reduction  of  the principal  balance  of such  investor's  Class A  or  Class M
Certificate may  be lower  than the  applicable Pass-Through  Rate.  Conversely,
slower  rates of  prepayments on  the Mortgage  Loans, and  therefore of amounts
distributable in  reduction of  principal balance  of  the Class  A or  Class  M
Certificates, may
 
                                      S-49
<PAGE>
coincide  with periods of  high prevailing interest  rates. During such periods,
the amount of principal distributions available to an investor for  reinvestment
at such high prevailing interest rates may be relatively small.
 
    As indicated under "Federal Income Tax Considerations" herein, the Class A-R
Certificateholder's  REMIC  taxable income  and the  tax liability  thereon will
exceed cash distributions to such holder during certain periods. There can be no
assurance as to the amount  by which such taxable  income or such tax  liability
will  exceed cash distributions  in respect of the  Class A-R Certificate during
any such period  and no representation  is made with  respect thereto under  any
principal  prepayment scenario or otherwise. DUE TO THE SPECIAL TAX TREATMENT OF
RESIDUAL INTERESTS, THE  AFTER-TAX RETURN OF  THE CLASS A-R  CERTIFICATE MAY  BE
SIGNIFICANTLY  LOWER THAN WOULD  BE THE CASE  IF THE CLASS  A-R CERTIFICATE WERE
TAXED AS A DEBT INSTRUMENT.
 
    As referred to herein, the  weighted average life of  a Subclass of Class  A
Certificates  and the Class M Certificates refers  to the average amount of time
that will elapse from the date of issuance of such Subclass or Class until  each
dollar  in  reduction of  the principal  balance  of such  Subclass or  Class is
distributed to the investor. The weighted  average life of each Subclass of  the
Class  A Certificates and the Class M  Certificates will be influenced by, among
other things, the rate and timing  of principal payments on the Mortgage  Loans,
which may be in the form of scheduled amortization or prepayments.
 
    Prepayments on mortgage loans are commonly measured relative to a prepayment
standard  or model. The  model used in this  Prospectus Supplement, the Standard
Prepayment Assumption ("SPA"),  represents an  assumed rate  of prepayment  each
month  relative  to the  then outstanding  principal  balance of  a pool  of new
mortgage loans. A prepayment assumption of 100% SPA assumes constant  prepayment
rates  of  0.2% per  annum of  the  then outstanding  principal balance  of such
mortgage loans in  the first  month of  the life of  the mortgage  loans and  an
additional  0.2% per annum  in each month thereafter  until the thirtieth month.
Beginning in the thirtieth month and in each month thereafter during the life of
the mortgage loans, 100% SPA assumes a constant prepayment rate of 6% per  annum
each  month. As used in the table below, "0% SPA" assumes prepayment rates equal
to  0%  of  SPA,  i.e.,  no  prepayments.  Correspondingly,  "75%  SPA"  assumes
prepayment rates equal to 75% of SPA, and so forth. SPA DOES NOT PURPORT TO BE A
HISTORICAL   DESCRIPTION  OF  PREPAYMENT  EXPERIENCE  OR  A  PREDICTION  OF  THE
ANTICIPATED RATE OF  PREPAYMENT OF  ANY POOL  OF MORTGAGE  LOANS, INCLUDING  THE
MORTGAGE LOANS.
 
    The  tables  set  forth  below  have  been  prepared  on  the  basis  of the
characteristics of the Mortgage  Loans that are expected  to be included in  the
Trust  Estate, as described above under "Description of the Mortgage Loans." The
tables assume, among other things, that (i) the scheduled payment in each  month
for each Mortgage Loan has been based on its outstanding balance as of the first
day of the month preceding the month of such payment, its Mortgage Interest Rate
and its remaining term to stated maturity, so that such scheduled payments would
amortize  the  remaining balance  by its  stated  maturity date,  (ii) scheduled
monthly payments of principal and interest on the Mortgage Loans will be  timely
received  on the first day of each  month (with no defaults), commencing June 1,
1992, (iii) the Seller does not repurchase any Mortgage Loan, as described under
"The Trust Estates--Mortgage Loans" in the Prospectus, and the Servicer does not
exercise its  option  to  purchase  the  Mortgage  Loans  and  thereby  cause  a
termination  of the  Trust Estate,  (iv) principal  prepayments on  the Mortgage
Loans will be received on the last day of each month commencing May 31, 1992  at
the respective constant percentages of SPA set forth in the tables and there are
no  Prepayment Interest  Shortfalls and (v)  each Mortgage Loan  has an original
term to maturity of 30 years. IT IS HIGHLY UNLIKELY THAT THE MORTGAGE LOANS WILL
PREPAY AT ANY CONSTANT RATE OR THAT ALL OF THE MORTGAGE LOANS WILL PREPAY AT THE
SAME RATE. In addition, there may be differences between the characteristics  of
the  mortgage loans  ultimately included  in the  Trust Estate  and the Mortgage
Loans which are expected to be included, as described herein. Any difference may
have an effect upon the actual percentages of initial Class A Subclass Principal
Balance of the Subclasses of Class A Certificates and initial principal  balance
of  the Class M  Certificates outstanding, the actual  weighted average lives of
the Subclasses of Class A Certificates and the Class M Certificates and the date
on which the  Class A  Subclass Principal  Balance of  any Subclass  of Class  A
Certificates  and the principal balance of  the Class M Certificates are reduced
to zero.

    Based upon  the foregoing  assumptions, the  following tables  indicate  the
weighted  average life of  each Subclass and Class  of Offered Certificates, and
set forth the percentages of the  initial Class A Subclass Principal Balance  of
each such Subclass, and, in the case of the Class M Certificates, of the initial
principal  balance of the  Class M Certificates that  would be outstanding after
each of the dates shown at various constant percentages of SPA.

(1) The  weighted average  life of an  Offered Certificate is  determined by (i)
    multiplying the  amount  of  each distribution  in  reduction  of  principal
    balance  by  the number  of  years from  the date  of  the issuance  of such
    Certificate to the related  Distribution Date, (ii)  adding the results  and
    (iii)  dividing  the  sum by  the  aggregate distributions  in  reduction of
    principal balance referred to in clause (i).

    Interest on Mortgage  Loans prepaid  in full, Liquidated  Loans and  partial
principal  prepayments (to the extent not applied on a Due Date) is accrued only
to the date of  prepayment or liquidation,  although any corresponding  interest
shortfall  with respect to  prepayments in full (but  not partial prepayments or
liquidations) in the month of  prepayment will be offset,  to the extent of  the
aggregate  of  the  Servicing  Fees  relating  to  mortgagor  payments  or other
recoveries distributed on the related Distribution Date. Interest accrued on the
Class A and Class M Certificates will  be reduced by the amount of any  interest
portions  of Realized Losses  allocated to such  Certificates as described under
"Description of the  Certificates--Interest" herein.  The yield on  the Class  A
Certificates  and the Class M Certificates will be less than the yield otherwise
produced by their  respective Pass-Through  Rates and  the prices  at which  the
Class  A  and Class  M  Certificates are  purchased  because the  interest which
accrues on the Mortgage Loans  during each month will  not be passed through  to
Certificateholders  until the 25th  day of the  month following the  end of such
month (or if such 25th day is  not a business day, the following business  day).
See "Description of the Certificates--Interest" herein and "Prepayment and Yield
Considerations" in the Prospectus.
 
                        POOLING AND SERVICING AGREEMENT
 
GENERAL
 
    The  Series 1992-14  Certificates will be  issued pursuant to  a Pooling and
Servicing Agreement to be dated as of the date of initial issuance of the Series
1992-14 Certificates (the "Pooling and  Servicing Agreement") among the  Seller,
the  Servicer and the Trustee. Reference is made to the Prospectus for important
additional information regarding  the terms  and conditions of  the Pooling  and
Servicing Agreement and the Series 1992-14 Certificates. See "Description of the
Certificates,"  "Servicing of the Mortgage Loans" and "The Pooling and Servicing
Agreement" in the Prospectus. Distributions  (other than the final  distribution
in  retirement of the Class  A Certificates of each Subclass  and of the Class M
Certificates) will be made by check mailed to the address of the person entitled
thereto as it appears on the Certificate Register. However, with respect to  any
holder  of  an  Offered Certificate  evidencing  at least  a  $5,000,000 initial
principal balance, distributions will be made  on the Distribution Date by  wire
transfer  in immediately  available funds,  provided that  the Servicer,  or the
paying agent acting on  behalf of the Servicer,  shall have been furnished  with
appropriate  wiring instructions not less than  seven business days prior to the
related Distribution Date. The final distribution in respect of each Class A and
Class M Certificate will  be made only upon  presentation and surrender of  such
Class  A or Class M Certificate at the office or agency appointed by the Trustee
specified in  the notice  of  final distribution  with  respect to  the  related
Subclass or Class.
 
    Unless  Definitive Certificates are issued  as described above, the Servicer
and the Trustee will treat DTC as the Holder of the Book-Entry Certificates  for
all  purposes, including  making distributions  thereon and  taking actions with
respect thereto. DTC will make book-entry transfers among its participants  with
respect  to the Book-Entry  Certificates; it will  also receive distributions on
the Book-Entry Certificates from the  Trustee and transmit them to  participants
for distribution to Beneficial Owners or their nominees.
 
VOTING
 
    With  respect  to  any provisions  of  the Pooling  and  Servicing Agreement
providing for  the action,  consent or  approval of  the holders  of all  Series
1992-14  Certificates evidencing specified Voting Interests in the Trust Estate,
the holders of  the Class A  Certificates will collectively  be entitled to  the
then  applicable Class A Percentage, and the holders of the Class M Certificates
will collectively be entitled to the then applicable percentage of the aggregate
Voting Interest  represented  by all  Series  1992-14 Certificates  obtained  by
dividing  the then-outstanding Class M Principal Balance by the sum of the then-
outstanding Class A  Principal Balance, Class  M Principal Balance  and Class  B
Principal  Balance and the holders of the Class B Certificates will collectively
be entitled to the balance of  the aggregate Voting Interest represented by  all
Series  1992-14  Certificates. The  aggregate Voting  Interests  of the  Class A
Certificates other than the Class A-14 Certificates, on any date will be 97%  of
the  Class A Percentage on such date. The aggregate Voting Interest of the Class
A-10 Certificates on any date will be 3% of the
 
                                      S-56
<PAGE>
Class A Percentage on such date. The aggregate Voting Interests of each Subclass
of Class A Certificates other than the Class A-14 Certificates on any date  will
be  equal to the product of  (a) 97% of the Class  A Percentage on such date and
(b) the fraction obtained by dividing the Class A Subclass Principal Balance  of
such  Subclass on such date by the  aggregate Class A Subclass Principal Balance
of the Class A Certificates other than the Class A-14 Certificates on such date.
The aggregate Voting Interests of the Class  M Certificates on any date will  be
100%  of the  percentage described  above for the  Class M  Certificates on such
date. Each Certificateholder of a Class or Subclass will have a Voting  Interest
equal  to the product of the Voting Interest  to which such Class or Subclass is
collectively entitled  and the  Percentage Interest  in such  Class or  Subclass
represented by such holder's Certificates. With respect to any provisions of the
Pooling  and Servicing  Agreement providing for  action, consent  or approval of
each Class or  Subclass of Certificates  or specified Classes  or Subclasses  of
Certificates,  each Certificateholder of a Subclass  will have a Voting Interest
in such Subclass equal  to such holder's Percentage  Interest in such  Subclass.
Unless  Definitive Certificates are issued as described above, Beneficial Owners
of Book-Entry  Certificates  may  exercise  their  voting  rights  only  through
Participants.
 
TRUSTEE
 
    The Trustee for the Series 1992-14 Certificates will be First Trust National
Association,  a national banking association. The  Corporate Trust Office of the
Trustee  is  located  at  First  Bank  Place  East,  220  South  Sixth   Street,
Minneapolis,  Minnesota 55402.  See "The  Pooling and  Servicing Agreement-- The
Trustee" in the Prospectus.
 
SERVICING COMPENSATION AND PAYMENT OF EXPENSES
 
    The Servicing Fee paid to the Servicer with respect to the servicing of each
Mortgage Loan  included  in  the  Trust Estate  underlying  the  Series  1992-14
Certificates  and administrative services provided by it will be 0.25% per annum
of the  outstanding principal  balance  of each  such  Mortgage Loan.  No  Fixed
Retained  Yield (as defined in the Prospectus)  will be retained with respect to
any of the Mortgage Loans. See "Servicing of the Mortgage Loans--Fixed  Retained
Yield,  Servicing Compensation  and Payment of  Expenses" in  the Prospectus for
information regarding other possible compensation to the Servicer. The  Servicer
will  pay all routine expenses incurred  in connection with its responsibilities
under the  Pooling  and  Servicing  Agreement,  subject  to  certain  rights  of
reimbursement  as  described in  the Prospectus.  The  servicing fees  and other
expenses of  the  REMIC  will be  allocated  to  the holder  of  the  Class  A-R
Certificate  who is an individual, estate, or trust (whether such Certificate is
held directly  or through  certain pass-through  entities) as  additional  gross
income  without a corresponding distribution of  cash, and any such investor (or
its owners, in the case of a pass-through entity) may be limited in its  ability
to  deduct such expenses for regular tax purposes  and may not be able to deduct
such expenses to any extent for  alternative minimum tax purposes. See  "Certain
Federal  Income  Tax  Consequences--Federal Income  Tax  Consequences  for REMIC
Certificates--Limitations on Deduction of Certain Expenses" in the Prospectus.
 
OPTIONAL TERMINATION
 
    At its option, the Servicer may purchase from the Trust Estate all remaining
Mortgage Loans,  and  thereby effect  early  retirement of  the  Series  1992-14
Certificates, on any Distribution Date when the Pool Scheduled Principal Balance
is  less than  10% of  the Cut-Off  Date Aggregate  Principal Balance.  Any such
purchase will be made only in  connection with a "qualified liquidation" of  the
REMIC  within the  meaning of  Section 860F(a)(4)(A)  of the  Code. The purchase
price will,  generally, be  equal to  the greater  of (i)  the unpaid  principal
balance  of each Mortgage Loan  plus the fair market  value of other property in
the Trust Estate and  (ii) the fair  market value of  the Trust Estate's  assets
plus,   in  each  case,  accrued  interest.   See  "The  Pooling  and  Servicing
Agreement--Termination; Purchase of Mortgage Loans" in the Prospectus.
 
                       FEDERAL INCOME TAX CONSIDERATIONS
 
    An election will be  made to treat  the Trust Estate,  and the Trust  Estate
will  qualify, as  a REMIC  for federal income  tax purposes  (the "REMIC"). The
Class A-1, Class A-2,  Class A-3, Class  A-4, Class A-5,  Class A-6, Class  A-7,
Class A-8, Class A-9, Class A-10, Class A-11, Class A-12, Class A-13 and Class M
 
                                      S-57
<PAGE>
Certificates  (collectively, the  "Regular Certificates") will  be designated as
regular interests in the REMIC and the Class A-R Certificate will be  designated
as  the residual interest in the REMIC. The Class A-R Certificate is a "Residual
Certificate" for purposes  of the  Prospectus. The Class  A-14 Certificates  and
each  subclass of the  Class B Certificates  will also be  designated as regular
interests in the  REMIC. See "Certain  Federal Income Tax  Consequences" in  the
Prospectus.
 
    The Offered Certificates will be treated as "qualifying real property loans"
for  mutual savings banks and domestic  building and loan associations, "regular
or residual interests in a REMIC"  for domestic building and loan  associations,
and  "real  estate assets"  for  real estate  investment  trusts, to  the extent
described in the Prospectus.
 
REGULAR CERTIFICATES
 
    The Regular Certificates generally will  be treated as debt instruments  for
federal  income  tax  purposes.  Holders of  the  Regular  Certificates  will be
required to report income  on such Certificates in  accordance with the  accrual
method  of accounting. The Class A-10  Certificates will be issued with original
issue discount  in  an  amount equal  to  the  excess of  all  distributions  of
principal  and interest  thereon (whether current  or accrued)  over their issue
price (including accrued interest). It is anticipated that the Class A-7,  Class
A-8,  Class A-9 and Class A-13 Certificates and the Class M Certificates will be
issued with original  issue discount in  an amount  equal to the  excess of  the
initial principal balances of such Subclasses (plus two days of accrued interest
at  the Pass-Through Rates  thereon) over their  issue prices (including accrued
interest). It is  also anticipated  that the Class  A-1, Class  A-2, Class  A-3,
Class A-4, Class A-5, Class A-11 and Class A-12 Certificates will be issued at a
premium  and that  the Class  A-6 Certificates  will be  issued with  DE MINIMIS
original issue discount for federal income tax purposes.
 
    The Prepayment Assumption (as defined in the Prospectus) that is to be  used
in  determining the rate of  accrual of original issue  discount and whether the
original issue discount  is considered DE  MINIMIS, and  that may be  used by  a
holder  of a Regular  Certificate to amortize premium,  will be calculated using
235% SPA. No representation is made as to the actual rate at which the  Mortgage
Loans will prepay.
 
RESIDUAL CERTIFICATE
 
    The  holder of the Class A-R Certificate  must include the taxable income or
loss of  the REMIC  in determining  its federal  taxable income.  The Class  A-R
Certificate  will remain outstanding for federal income tax purposes until there
are no Certificates of  any other Class  outstanding. PROSPECTIVE INVESTORS  ARE
CAUTIONED  THAT THE CLASS  A-R CERTIFICATEHOLDER'S REMIC  TAXABLE INCOME AND THE
TAX LIABILITY  THEREON WILL  EXCEED  CASH DISTRIBUTIONS  TO SUCH  HOLDER  DURING
CERTAIN  PERIODS,  IN  WHICH  EVENT  THE  HOLDER  THEREOF  MUST  HAVE SUFFICIENT
ALTERNATIVE SOURCES  OF FUNDS  TO PAY  SUCH TAX  LIABILITY. Furthermore,  it  is
anticipated that all of the taxable income of the REMIC includible by the holder
of  the  Class A-R  Certificate will  be treated  as "excess  inclusion" income,
resulting in (i) the  inability of such  holder to use  net operating losses  to
offset  such income,  (ii) the treatment  of such income  as "unrelated business
taxable income" to certain holders who  are otherwise tax-exempt, and (iii)  the
treatment  of such income as subject to  30% withholding tax to certain non-U.S.
investors, with no exemption or treaty reduction.
 
    Under proposed  Treasury  regulations  (the  "Proposed  REMIC  Regulations")
released  by the Internal Revenue Service on  September 27, 1991, since the fair
market value of the Class A-R Certificate will not exceed 2% of the fair  market
value of the REMIC, the Class A-R Certificate will not have "significant value,"
and  thrift institutions  will not  be permitted  to offset  their net operating
losses against such  excess inclusion  income. In addition,  under the  Proposed
REMIC  Regulations,  the  Class  A-R  Certificate will  be  considered  to  be a
"noneconomic residual interest," with the result that transfers thereof will  be
disregarded  for federal income  tax purposes if any  significant purpose of the
transfer was to  impede the assessment  or collection of  tax. Accordingly,  the
transferee  affidavit  used  for transfers  of  the Class  A-R  Certificate will
require the transferee to state, among other things, that it has no intention to
impede the assessment or collection of any federal, state or local income  taxes
legally  required to be paid with respect to a Class A-R Certificate and that it
will   not   transfer   the   Class   A-R   Certificate   to   any   person   or
 
                                      S-58
<PAGE>
entity  that it has reason to believe has the intention to impede the assessment
or collection of such  taxes. Finally, the Class  A-R Certificate generally  may
not  be transferred to persons who are not U.S. Persons (as defined herein). See
"Description of  the Certificates--Restrictions  on Transfer  of the  Class  A-R
Certificate" herein and "Certain Federal Income Tax Consequences--Federal Income
Tax    Consequences   for   REMIC   Certificates--Taxation   of   the   Residual
Certificates--Limitations  on  Offset   or  Exemption  of   REMIC  Income"   and
"--Tax-Related  Restrictions on Transfer  of Residual Certificates-- Noneconomic
Residual Interests" in the Prospectus.
 
    An individual, trust or estate that  holds a Class A-R Certificate  (whether
such  Certificate is  held directly  or indirectly  through certain pass-through
entities) also may  have additional  gross income with  respect to,  but may  be
subject  to limitations on the deductibility  of, Servicing Fees on the Mortgage
Loans and other administrative expenses of the REMIC in computing such  holder's
regular  tax liability, and may  not be able to deduct  such fees or expenses to
any extent  in computing  such holder's  alternative minimum  tax liability.  In
addition,  some portion of a purchaser's basis  in the Class A-R Certificate may
not be recovered until termination of the REMIC. Furthermore, the federal income
tax consequences of any consideration paid to a transferee on a transfer of  the
Class   A-R  Certificate  are  unclear;   any  such  transferee  receiving  such
consideration should consult its tax advisors.
 
    Legislation has been proposed that would  generally treat all partners in  a
"large   partnership"  as   Disqualified  Organizations   (as  defined   in  the
Prospectus),  thus  subjecting  such  a   partnership  to  tax  annually  as   a
Pass-Through  Entity  (as  defined  in  the Prospectus)  on  all  of  its excess
inclusion income  at the  highest  corporate rate.  The legislation  would  also
disallow  70%  of  any large  partnership's  miscellaneous  itemized deductions,
including the deductions  for Servicing  Fees on  the Mortgage  Loans and  other
administrative expenses properly allocable to the Class A-R Certificate although
the  remaining deductions would not be  subject to the applicable limitations at
the partner level. A "large  partnership" generally would include a  partnership
having  250  or  more  partners.  This proposed  legislation,  which  was  to be
effective for taxable years ending on or after December 31, 1992 was included in
a Bill that  was passed by  Congress but vetoed  by the President  on March  20,
1992.  No  prediction can  be made  regarding whether  such legislation  will be
reintroduced or,  if reintroduced,  whether  it will  be enacted.  See  "Certain
Federal  Income  Tax  Consequences--Federal Income  Tax  Consequences  for REMIC
Certificates--Taxation of  Residual  Certificates--Tax-Related  Restrictions  on
Transfer  of Residual  Certificates" and  "--imitations on  Deduction of Certain
Expenses" in the Prospectus.
 
    DUE TO  THE  SPECIAL TAX  TREATMENT  OF RESIDUAL  INTERESTS,  THE  EFFECTIVE
AFTER-TAX  RETURN OF THE  CLASS A-R CERTIFICATE MAY  BE SIGNIFICANTLY LOWER THAN
WOULD BE THE CASE IF THE CLASS A-R CERTIFICATE WERE TAXED AS A DEBT INSTRUMENT.
 
                              ERISA CONSIDERATIONS
 
    The Class A-R  Certificate may  not be purchased  by or  transferred to  any
person  which is an employee benefit plan within the meaning of Section 3(3) of,
and which is subject to  the fiduciary duty rules  of Title 1, Sections  401-414
of,  the Employee Retirement Income Security  Act of 1974, as amended ("ERISA"),
or Code Section 4975 or any person utilizing the assets of such employee benefit
plan (an "ERISA Plan"). Accordingly,  the following discussion does not  purport
to  discuss the considerations under ERISA or  Code Section 4975 with respect to
the purchase, acquisition or resale of the Class A-R Certificate.
 
    In addition,  under current  law the  purchase and  holding of  the Class  M
Certificates  by  or  on behalf  of  an  ERISA Plan  may  result  in "prohibited
transactions" within the meaning of ERISA and Code Section 4975. Transfer of the
Class M  Certificates will  not be  made unless  the transferee  (i) executes  a
representation  letter in form and substance satisfactory to the Trustee stating
that it is not, and is not acting on behalf of, any such ERISA Plan or using the
assets of  any such  ERISA Plan  to effect  such purchase  or (ii)  provides  an
opinion  of counsel in form  and substance satisfactory to  the Trustee that the
purchase or holding of the  Class M Certificates by or  on behalf of such  ERISA
Plan  will not result in the assets of the Trust Estate being deemed to be "plan
assets"   and   subject   to   the   prohibited   transaction   provisions    of
 
                                      S-59
<PAGE>
ERISA  and the Code and will not subject the Servicer, the Seller or the Trustee
to any obligation in addition to  those undertaken in the Pooling and  Servicing
Agreement.  The  Class  M Certificates  will  contain a  legend  describing such
restrictions on transfer and  the Pooling and  Servicing Agreement will  provide
that  any  attempted  or  purported  transfer  in  violation  of  these transfer
restrictions will be  null and void  and will  vest no rights  in any  purported
transferee.  Accordingly, the following  discussion does not  purport to discuss
the considerations  under  ERISA  or  Code Section  4975  with  respect  to  the
purchase, acquisition or resale of the Class A-R or Class M Certificates.
 
    As  described in the Prospectus under  "ERISA Considerations," ERISA and the
Code impose certain duties and restrictions  on ERISA Plans and certain  persons
who  perform services for ERISA Plans.  For example, unless exempted, investment
by an  ERISA  Plan in  the  Offered  Certificates may  constitute  a  prohibited
transaction  under ERISA or the Code. There are certain exemptions issued by the
United States  Department of  Labor (the  "DOL") that  may be  applicable to  an
investment  by  an  ERISA  Plan  in  the  Offered  Certificates,  including  the
individual administrative exemption described  below and Prohibited  Transaction
Class  Exemption 83-1 ("PTE  83-1"). For a further  discussion of the individual
administrative exemption and  PTE 83-1,  including the  necessary conditions  to
their  applicability, and other  important factors to be  considered by an ERISA
Plan  contemplating   investing  in   the  Offered   Certificates,  see   "ERISA
Considerations" in the Prospectus.
 
    On  October  17,  1989, the  DOL  issued  to the  Underwriter  an individual
administrative exemption, Prohibited Transaction  Exemption 89-90, 54 Fed.  Reg.
42597  (the "Exemption"),  from certain of  the prohibited  transaction rules of
ERISA with  respect to  the initial  purchase, the  holding and  the  subsequent
resale  by an ERISA  Plan of certificates  in pass-through trusts  that meet the
conditions and requirements of the Exemption.  The Exemption might apply to  the
acquisition,  holding and  resale of  the Offered  Certificates, other  than the
Class A-R or  Class M Certificates,  by an ERISA  Plan, provided that  specified
conditions are met.
 
    Among  the conditions which would have to  be satisfied for the Exemption to
apply to the  acquisition by an  ERISA Plan of  the Offered Certificates,  other
than  the Class A-R  and Class M  Certificates, is the  condition that the ERISA
Plan investing  in  the Offered  Certificates  be an  "accredited  investor"  as
defined  in  Rule  501(a)(1) of  Regulation  D  of the  Securities  and Exchange
Commission under the Securities Act.
 
    Before purchasing an Offered Certificate, other than the Class A-R or  Class
M  Certificates, a fiduciary of an ERISA  Plan should make its own determination
as to the availability of the exemptive relief provided in the Exemption or  the
availability  of  any  other prohibited  transaction  exemptions  (including PTE
83-1), and whether the  conditions of any such  exemption will be applicable  to
the Offered Certificates, other than the Class A-R and Class M Certificates. Any
fiduciary   of  an  ERISA  Plan  considering  whether  to  purchase  an  Offered
Certificate, other than  the Class  A-R and  Class M  Certificates, should  also
carefully  review with its own legal advisors the applicability of the fiduciary
duty and  prohibited  transaction provisions  of  ERISA  and the  Code  to  such
investment. See "ERISA Considerations" in the Prospectus.
 
                                LEGAL INVESTMENT
 
    The  Offered  Certificates  constitute  "mortgage  related  securities"  for
purposes  of  the  Secondary  Mortgage  Market  Enhancement  Act  of  1984  (the
"Enhancement  Act") and, as such, are  legal investments for certain entities to
the extent provided in the Enhancement Act. However, institutions subject to the
jurisdiction of the  Office of  the Comptroller of  the Currency,  the Board  of
Governors   of  the  Federal  Reserve  System,  the  Federal  Deposit  Insurance
Corporation, the  Office  of  Thrift  Supervision,  the  National  Credit  Union
Administration   or  state  banking  or   insurance  authorities  should  review
applicable rules, supervisory policies and  guidelines of these agencies  before
purchasing any of the Offered Certificates, as certain Subclasses of the Class A
Certificates  or  the  Class  M  Certificates may  be  deemed  to  be unsuitable
investments under  one or  more  of these  rules,  policies and  guidelines  and
certain restrictions may apply to investments in other Subclasses of the Class A
Certificates  or the Class M Certificates. It  should also be noted that certain
states recently have enacted, or have proposed
 
                                      S-60
<PAGE>
enacting, legislation  limiting  to  varying  extents  the  ability  of  certain
entities  (in  particular insurance  companies)  to invest  in  mortgage related
securities.  Investors  should  consult  with   their  own  legal  advisors   in
determining  whether and  to what  extent Offered  Certificates constitute legal
investments for such investors. See "Legal Investment" in the Prospectus.
 
                                SECONDARY MARKET
 
    There will not  be any market  for the Offered  Certificates offered  hereby
prior  to the issuance thereof. The Underwriter intends to act as a market maker
in the Offered  Certificates, subject  to applicable provisions  of federal  and
state  securities  laws  and  other regulatory  requirements,  but  is  under no
obligation to do so. There  can be no assurance that  a secondary market in  the
Offered  Certificates will develop  or, if such  a market does  develop, that it
will provide holders of Offered Certificates with liquidity of investment at any
particular time or for the life of the Offered Certificates.
 
                                  UNDERWRITING
 
    Subject to the terms and conditions  of the underwriting agreement dated  as
of  April 21, 1992 (the "Underwriting Agreement") among the Seller, PHMC and The
First Boston  Corporation,  as  underwriter  (the  "Underwriter"),  the  Offered
Certificates  offered  hereby  are  being  purchased  from  the  Seller  by  the
Underwriter upon issuance. The Underwriter is  committed to purchase all of  the
Offered  Certificates if any Offered Certificates are purchased. The Underwriter
has advised the Seller that it proposes to offer the Offered Certificates,  from
time  to  time,  for sale  in  negotiated  transactions or  otherwise  at prices
determined at the  time of sale.  Proceeds to the  Seller from the  sale of  the
Offered  Certificates will be approximately  97.328125% of the initial aggregate
principal balance of the Offered Certificates, plus accrued interest thereon and
on the aggregate initial principal balance of the Class A-14 Certificates at the
rate of 8.00% per annum  from May 1, 1992 to  (but not including) May 27,  1992,
before  deducting expenses payable by the  Seller. The Underwriter, which is not
an affiliate of the Seller, has advised the Seller that the Underwriter has  not
allocated  the purchase price paid to the Seller among the Subclasses or Classes
of Offered Certificates. The Underwriter  and any dealers that participate  with
the Underwriter in the distribution of the Offered Certificates may be deemed to
be  underwriters,  and any  discounts or  commissions received  by them  and any
profit on  the resale  of  Offered Certificates  by them  may  be deemed  to  be
underwriting  discounts or  commissions, under  the Securities  Act of  1933, as
amended (the "Securities Act").
 
    The Underwriting Agreement provides that the Seller and PHMC will  indemnify
the  Underwriter against certain  civil liabilities under  the Securities Act or
contribute to payments which the Underwriter may be required to make in  respect
thereof.
 
                                 LEGAL MATTERS
 
    Certain  legal matters in  connection with the  Offered Certificates offered
hereby will be passed upon for the Seller by Cadwalader, Wickersham & Taft,  New
York, New York, and for the Underwriter by Brown & Wood, New York, New York.
 
                                USE OF PROCEEDS
 
    The  net proceeds to be  received from the sale  of the Offered Certificates
offered hereby will be applied  by the Seller to the  purchase from PHMC of  the
Mortgage  Loans represented by  the Series 1992-14  Certificates. It is expected
that PHMC will  use the  proceeds from  the sale of  the Mortgage  Loans to  the
Seller  for its  general business  purposes, including,  without limitation, the
origination or acquisition of new mortgage loans and the repayment of borrowings
incurred to  finance  the  origination  or acquisition  of  the  Mortgage  Loans
underlying the Series 1992-4 Certificates.

                                    RATINGS
 
    It  is a  condition to the  issuance of  the Class A  Certificates that each
Subclass will have been rated "AAA" by S&P  and Fitch. It is a condition to  the
issuance of the Class M Certificates that they shall have been rated "AA" by S&P
and  Fitch.  A security  rating is  not a  recommendation to  buy, sell  or hold
securities and may  be subject  to revision  or withdrawal  at any  time by  the
assigning  rating agency. Each security rating should be evaluated independently
of any other security rating.
 
    The ratings  of  S&P  on  mortgage  pass-through  certificates  address  the
likelihood  of the receipt by certificateholders  of payments required under the
related pooling and servicing agreement.  S&P's ratings take into  consideration
the credit quality of the mortgage pool, including any credit support providers,
structural and legal aspects associated with the certificates, and the extent to
which  the payment  stream on  the mortgage  pool is  adequate to  make payments
required under  the certificates.  S&P's ratings  on such  certificates do  not,
however,  constitute  a  statement  regarding frequency  of  prepayments  on the
mortgages.
 
    The ratings  of  Fitch on  mortgage  pass-through certificates  address  the
likelihood  of the receipt  by certificateholders of  all distributions to which
such certificateholders  are  entitled.  Fitch's  rating  opinions  address  the
structural  and legal  aspects associated  with the  certificates, including the
nature of  the  underlying  mortgage  loans.  Fitch's  ratings  on  pass-through
certificates  do  not represent  any  assessment of  the  likelihood or  rate of
principal prepayments.
 
    The ratings of  S&P and  Fitch do  not address  the possibility  that, as  a
result  of principal  prepayments, Certificateholders  may receive  a lower than
anticipated yield.
 
    The Seller has  not requested a  rating on the  Offered Certificates of  any
Subclass  or Class  by any rating  agency other than  S&P and Fitch  and has not
provided any information with respect to the Mortgage Loans to any other  rating
agency.  There can be no assurance that  any rating assigned by any other rating
agency to the Offered Certificates will be as high as those assigned by S&P  and
Fitch.

THE PRUDENTIAL HOME MORTGAGE SECURITIES COMPANY, INC.
                                     SELLER
                       MORTGAGE PASS-THROUGH CERTIFICATES
                              (ISSUABLE IN SERIES)
                               -----------------
 
    The  Prudential  Home Mortgage  Securities  Company, Inc.  (the  "Seller" or
"PHMSC") may sell from time to time under this Prospectus and related Prospectus
Supplements Mortgage Pass-Through Certificates (the "Certificates"), issuable in
series (each, a "Series") consisting of one or more classes (each, a "Class") of
Certificates.
 
    The Certificates of a Series  will represent beneficial ownership  interests
in  a separate  trust formed  by the Seller.  Unless otherwise  specified in the
applicable Prospectus  Supplement, the  property of  each such  trust (for  each
Series,  the "Trust Estate") will be  comprised primarily of fixed or adjustable
interest rate, conventional, monthly pay, fully-amortizing first mortgage  loans
(the  "Mortgage Loans"), secured by  one- to four-family residential properties.
Unless otherwise specified in the applicable prospectus supplement, the Mortgage
Loans will have been acquired by  the Seller from its affiliate, The  Prudential
Home  Mortgage Company, Inc. ("PHMC"), and will have been underwritten to PHMC's
underwriting standards. Unless otherwise specified in the applicable  prospectus
supplement,  all of  the Mortgage Loans  will be  serviced by PHMC  (PHMC in its
capacity as servicer being referred to hereafter as the "Servicer").
 
    The Certificates of  a Series will  consist of  (i) one or  more Classes  of
Certificates  representing fractional  undivided interests in  all the principal
payments and the interest  payments, to the extent  of the related Net  Mortgage
Interest  Rate (as  defined herein),  on the  related Mortgage  Loans ("Standard
Certificates"), (ii) one or more Classes of Certificates representing fractional
undivided interests  in all  or  specified portions  of the  principal  payments
and/or  interest payments,  to the extent  of the related  Net Mortgage Interest
Rate, on the related Mortgage Loans  ("Stripped Certificates"), or (iii) two  or
more Classes of Certificates ("Multi-Class Certificates"), each of which will be
assigned  a principal balance  (a "Stated Amount"),  and each of  which may bear
interest on the Stated Amount at a fixed rate (which may be zero) specified  in,
or  a  variable  rate  determined as  specified  in,  the  applicable Prospectus
Supplement (the "Interest Rate"). Any Class of Certificates may be divided  into
two or more subclasses (each, a "Subclass").
 
    Each  Series of Certificates may include one or more Classes of Certificates
(the "Subordinated Certificates") that are subordinate in right of distributions
to such rights of one or more of  the other Classes of such Series (the  "Senior
Certificates").  If  specified  in  the  applicable  Prospectus  Supplement, the
relative interests of the Senior Certificates and the Subordinated  Certificates
of  a Series in the Trust Estate may  be subject to adjustment from time to time
on the basis of distributions received  in respect thereof. Any Class of  Senior
Certificates  or Subordinated Certificates  may, as described  above, be divided
into two or more Subclasses. If  specified in the Prospectus Supplement,  credit
support  may also be  provided for any Series  of Certificates in  the form of a
guarantee, letter of  credit, mortgage pool  insurance policy or  other form  of
credit enhancement as described herein or therein.
 
    Except  for  the  Seller's  limited obligation  in  connection  with certain
breaches of its  representations and warranties  and certain other  undertakings
and  PHMC's obligations as  Servicer, neither the Seller,  the Servicer, nor any
affiliate of the Seller or the Servicer, will have any obligations with  respect
to  the Certificates. In the event of  delinquencies in payments on the Mortgage
Loans, the Servicer will be obligated to make advances which it determines  will
be recoverable from future payments and collections on the Mortgage Loans.
 
    An election will be made to treat each Trust Estate (or a segregated pool of
assets  therein) underlying a Series of  Multi-Class Certificates or a Series of
Certificates in which the relative interests in the Trust Estate of the  Classes
of  Senior Certificates and Subordinated  Certificates are subject to adjustment
as a "real estate  mortgage investment conduit" (a  "REMIC") for federal  income
tax  purposes. Such an election may also be made with respect to any other Trust
Estate. See "Certain Federal Income Tax Consequences."
 
    There will have  been no public  market for the  Certificates of any  Series
prior to the offering thereof. No assurance can be given that such a market will
develop,   or   that  if   such  a   market  does   develop,  it   will  provide
Certificateholders with liquidity of investment or will continue for the life of
the Certificates.
                             ---------------------
 
   THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES
     AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE
      SECURITIES  AND  EXCHANGE  COMMISSION   OR  ANY  STATE   SECURITIES
       COMMISSION   PASSED  UPON  THE  ACCURACY   OR  ADEQUACY  OF  THIS
        PROSPECTUS. ANY REPRESENTATION TO  THE CONTRARY IS A  CRIMINAL
                                    OFFENSE.
                              -------------------
 
    The Certificates may be sold from time to time by the Seller through dealers
or  agents,  through  underwriting  syndicates  led  by  one  or  more  managing
underwriters or through  one or  more underwriters  acting alone.  See "Plan  of
Distribution."  Affiliates of the Seller may from  time to time act as agents or
underwriters in connection  with the sale  of the Certificates.  The terms of  a
particular  offering will be set forth  in the Prospectus Supplement relating to
such offering.
 
    THIS PROSPECTUS MAY NOT BE USED  TO CONSUMMATE SALES OF CERTIFICATES  UNLESS
ACCOMPANIED  BY  THE  PROSPECTUS SUPPLEMENT  RELATING  TO THE  OFFERING  OF SUCH
CERTIFICATES.

Loans--Evidence  as to Compliance." Copies of  the monthly and annual statements
provided by the Servicer to the Trustee will be furnished to  Certificateholders
of  each Series upon request  addressed to the Servicer  c/o The Prudential Home

                        to receive current distributions on the related Mortgage
                        Loans and (if so specified in the applicable  Prospectus
                        Supplement)  by the establishment of a reserve fund (the
                        "Subordination  Reserve  Fund")  with  respect  to  each
                        Series   of  Certificates  that   includes  a  Class  of
                        Subordinated  Certificates.  Any  Subordination  Reserve
                        Fund  may be  funded initially with  the Initial Deposit
                        (as defined  herein)  in  an  amount  specified  in  the
                        applicable Prospectus Supplement, and may be funded from

                        otherwise distributable to the Subordinated
                        Certificateholders in  the  manner  and  to  the  extent
                        specified  in the applicable  Prospectus Supplement. The

                        intended   to   provide   liquidity,   but   in  certain
                        circumstances the  Subordination Reserve  Fund could  be
                        depleted   and,   if   other   amounts   available   for
                        distribution are insufficient, shortfalls in
                        distributions to  the  Senior  Certificateholders  could
                        result.  Until  the  Subordinated Amount  is  reduced to
                        zero, Senior  Certificateholders  will  be  entitled  to
                        receive  the amount of any such shortfall, together with

                        next   Distribution  Date   (as  defined   herein).  The
                        Subordinated  Amount  is  intended  to  protect   Senior
                        Certificateholders  against  losses, however,  if losses
                        realized on the  Mortgage Loans  in a  Trust Estate  are
                        exceptionally  high Senior  Certificateholders will bear
                        their proportionate share of any losses realized on  the
                        related  Mortgage  Loans  in  excess  of  the applicable
                        Subordinated Amount.

                               THE TRUST ESTATES
 
GENERAL
 
    The  Trust Estate for  each Series of Certificates  will consist of Mortgage
Loans evidenced by promissory notes (the "Mortgage Notes") secured by mortgages,
deeds of trust or  other instruments creating first  liens (the "Mortgages")  on
some  or all of the  following types of property  (as so secured, the "Mortgaged
Properties"), to the extent set  forth in the applicable Prospectus  Supplement:
(i)  one- to four-family detached residences, (ii) townhouses, (iii) condominium
units, (iv) units within  planned unit developments,  (v) long-term leases  with
respect  to any of the  foregoing, and (vi) shares  issued by private non-profit
housing corporations  ("cooperatives") and  the  related proprietary  leases  or
occupancy agreements granting exclusive rights to occupy specified units in such
cooperatives'  buildings.  In addition,  a Trust  Estate  will also  include (i)
amounts held from  time to  time in the  related Certificate  Account, (ii)  the
Seller's  interest in  any primary  mortgage insurance,  hazard insurance, title
insurance or other  insurance policies relating  to a Mortgage  Loan, (iii)  any
property  which initially secured a Mortgage Loan and which has been acquired by
foreclosure or trustee's sale or deed in lieu of foreclosure or trustee's  sale,
(iv)  if applicable, and  to the extent  set forth in  the applicable Prospectus
Supplement, any Subordination Reserve Fund and/or any other reserve fund, (v) if
applicable, and to the extent set forth in the applicable Prospectus Supplement,
contractual obligations of any person to make payments in respect of any form of
credit enhancement or any interest subsidy agreement, and (vi) such other assets
as may be specified  in the applicable  Prospectus Supplement. Unless  otherwise
specified  in the  applicable Prospectus Supplement,  the Trust  Estate will not
include,  however,  the  portion  of  interest  on  the  Mortgage  Loans   which
constitutes  the Fixed  Retained Yield, if  any. See "Servicing  of the Mortgage
Loans--Fixed Retained Yield; Servicing Compensation and Payment of Expenses."
 
MORTGAGE LOANS
 
    The Mortgage Loans will have been acquired by the Seller from its  affiliate
PHMC  or another affiliate. The Mortgage Loans will have been originated by PHMC
for its  own account  or for  the  account of  an affiliate  or will  have  been
acquired  by PHMC for  its own account or  for the account  of an affiliate from
other mortgage loan originators. Each Mortgage Loan will have been  underwritten
to   PHMC's  standards.  See  "PHMC--  Mortgage  Loan  Production  Sources"  and
"--Mortgage Loan Underwriting." The Prospectus  Supplement for each Series  will
set  forth the  respective number  and principal  amounts of  Mortgage Loans (i)
originated by PHMC for its own account or for the account of its affiliates  and
(ii)  purchased by PHMC for its own account or for the account of its affiliates
from other  mortgage  loan originators  through  PHMC's mortgage  loan  purchase
programs.
 
    Each  of the  Mortgage Loans will  be secured  by a Mortgage  on a Mortgaged
Property located in any of the 50 states or the District of Columbia. Generally,
the land underlying a Mortgaged Property will consist of five acres or less  but
may  consist of greater acreage in PHMC's  discretion. The Mortgage Loans may be
secured by leases on real property  under circumstances that PHMC determines  in
its  discretion  are commonly  acceptable  to institutional  mortgage investors.
Generally, a  Mortgage Loan  will be  secured  by a  lease only  if the  use  of
leasehold  estates as security for mortgage loans  is customary in the area, the
lease is not subject to any prior  lien that could result in termination of  the
lease  and the term  of the lease ends  at least five  years beyond the maturity
date of the related Mortgage Loan. The Prospectus Supplement will set forth  the
geographic  distribution of  Mortgaged Properties  and the  number and aggregate
unpaid principal  balances  of  the  Mortgage Loans  by  category  of  Mortgaged
Property.
 
    The  Prospectus Supplement for each Series will  also set forth the range of
original terms  to maturity  of the  Mortgage  Loans in  the Trust  Estate,  the
weighted  average remaining term to stated maturity  at the Cut-Off Date of such
Mortgage Loans, the earliest and latest  months of origination of such  Mortgage
Loans,  the range  of Mortgage  Interest Rates  and Net  Mortgage Interest Rates
borne by such Mortgage Loans, if  such Mortgage Loans have varying Net  Mortgage
Interest Rates, the weighted average Net Mortgage Interest
 
                                       12
<PAGE>
Rate  at the  Cut-Off Date  of such Mortgage  Loans, the  range of Loan-to-Value
Ratios at  the  time of  origination  of such  Mortgage  Loans and  the  highest
outstanding principal balance at origination of any such Mortgage Loan.
 
    Unless  otherwise specified in the  applicable Prospectus Supplement, all of
the Mortgage Loans in a Trust Estate will have monthly payments due on the first
of each month (each, a "Due Date") and will be fully-amortizing Mortgage  Loans,
each  with a fixed rate of interest and  level monthly payments over the term of
the Mortgage Loan. If  so specified in the  applicable Prospectus Supplement,  a
Trust  Estate may include fully amortizing,  adjustable rate Mortgage Loans with
Mortgage Interest Rates adjusted  periodically, in the  manner specified in  the
related  Prospectus  Supplement. Unless  otherwise  specified in  the applicable
Prospectus Supplement, no adjustable interest rate Mortgage Loan will be subject
to a  possibility  of negative  amortization.  If specified  in  the  applicable
Prospectus Supplement, fixed rates on certain Mortgage Loans may be converted to
adjustable rates and adjustable rates on certain Mortgage Loans may be converted
to  fixed rates, in each case after  origination of such Mortgage Loans and upon
the satisfaction  of other  conditions specified  in the  applicable  Prospectus
Supplement.  Unless otherwise specified in the applicable Prospectus Supplement,
in either  such event,  the Pooling  and Servicing  Agreement will  require  the
Servicer  to repurchase each such converted Mortgage Loan at the price set forth
in  the  applicable  Prospectus  Supplement.  If  specified  in  the  applicable
Prospectus  Supplement, a  Trust Estate  may contain  convertible Mortgage Loans
which have converted prior to  the formation of the  Trust Estate and which  are
subject to no further conversions.
 
    Unless  otherwise  specified  in the  applicable  Prospectus  Supplement, no
Mortgage Loan will have  had at origination a  Loan-to-Value Ratio in excess  of
90%.  The Loan-to-Value Ratio  is the ratio,  expressed as a  percentage, of the
principal amount of the Mortgage  Loan at origination to  the lesser of (i)  the
appraised  value  of  the  related  Mortgaged  Property,  as  established  by an
appraisal obtained by the originator generally no more than four months prior to
origination, or  (ii) the  sale price  for  such property.  For the  purpose  of
calculating  the Loan-to-Value Ratio of any Mortgage  Loan that is the result of
the refinancing (including a refinancing for  "equity take out" purposes) of  an
existing mortgage loan, the appraised value of the related Mortgaged Property is
generally  determined by reference  to an appraisal  obtained in connection with
the origination  of the  replacement  loan. Unless  otherwise specified  in  the
related  Prospectus Supplement,  with respect  to a  Mortgage Loan  secured by a
second home,  an  owner-occupied  cooperative,  a high  rise  condominium  or  a
non-owner  occupied property, the  Loan-to-Value Ratio will  not exceed 80%, and
with respect to a Mortgage Loan which is made to refinance, for equity take  out
purposes,  an  existing  mortgage loan  on  a non-owner  occupied  property, the
Loan-to-Value Ratio  will generally  not  exceed 75%.  Mortgage Loans  having  a
Loan-to-Value  Ratio in excess  of 80% will  not be covered  by primary mortgage
insurance,  except  to  the  extent  specified  in  the  applicable   Prospectus
Supplement. See "PHMC--Mortgage Loan Underwriting."
 
    No  assurance  can be  given that  values of  the Mortgaged  Properties have
remained or will remain at  the levels which existed  on the dates of  appraisal
(or,  where applicable, recertification of value) of the related Mortgage Loans.
If residential real estate  values generally or  in particular geographic  areas
decline  such  that  the outstanding  balances  of  the Mortgage  Loans  and any
secondary financing on  the Mortgaged  Properties in a  particular Trust  Estate
become  equal to or greater than the values of the related Mortgaged Properties,
the actual rates of delinquencies, foreclosures and losses could be higher  than
those  now generally experienced in the  mortgage lending industry and those now
experienced  in  PHMC's  servicing  portfolio.  In  addition,  adverse  economic
conditions generally, in particular geographic areas or industries, or affecting
particular  segments of the  borrowing community (such  as mortgagors relying on
commission income and self-employed mortgagors)  and other factors which may  or
may  not  affect real  property  values, including  the  purposes for  which the
Mortgage Loans were made  and the uses of  the Mortgaged Properties, 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
 
                                       13
<PAGE>
any Trust Estate. See "PHMC--Mortgage Loan Underwriting" and "Description of the
Certificates--Weighted Average Life of Certificates" herein. To the extent  that
such  losses are not covered  by the methods of  credit support or the insurance
policies described herein, they will be borne by holders of the Certificates  of
the Series evidencing interests in such Trust Estate.
 
    Unless  otherwise  provided  in the  applicable  Prospectus  Supplement, all
Mortgage Loans will  be covered by  an appropriate standard  form American  Land
Title  Association ("ALTA") title  insurance policy, or  a substantially similar
policy or  form  of  insurance  acceptable  to  the  Federal  National  Mortgage
Association ("FNMA") or the Federal Home Loan Mortgage Corporation ("FHLMC").
 
    If  so specified in the applicable Prospectus Supplement, a Trust Estate may
contain  Mortgage  Loans  subject  to  temporary  interest  subsidy   agreements
("Subsidy  Loans") pursuant  to which the  monthly payments made  by the related
mortgagors will be  less than the  scheduled monthly payments  on such  Mortgage
Loans  with the present  value of the resulting  difference in payment ("Subsidy
Payments") being provided  by the  employer of  the mortgagor,  generally on  an
annual   basis.  Unless   otherwise  specified  in   the  applicable  Prospectus
Supplement, Subsidy Payments  will be  placed in a  custodial account  ("Subsidy
Account")  by  the  Servicer. Despite  the  existence  of a  subsidy  program, a
mortgagor remains  primarily  liable for  making  all scheduled  payments  on  a
Subsidy  Loan and for all other obligations provided for in the related Mortgage
Note and Mortgage Loan.
 
    Subsidy Loans are offered by employers generally through either a  graduated
or  fixed  subsidy loan  program, or  a  combination thereof.  The terms  of the
subsidy agreements relating  to Subsidy Loans  generally range from  one to  ten
years.  The subsidy agreements relating to  Subsidy Loans made under a graduated
program generally will  provide for  subsidy payments that  result in  effective
subsidized  interest rates between  three percentage points  and five percentage
points below  the Mortgage  Interest  Rates specified  in the  related  Mortgage
Notes.  Generally, under a graduated program, the subsidized rate for a Mortgage
Loan will increase approximately one percentage  point per year until it  equals
the full Mortgage Interest Rate. For example, if the initial subsidized interest
rate is five percentage points below the Mortgage Interest Rate in year one, the
subsidized  rate  will increase  to four  percentage  points below  the Mortgage
Interest Rate in year two, and likewise until year six, when the subsidized rate
will equal the Mortgage Interest Rate. Where the subsidy agreements relating  to
Subsidy  Loans are in effect for longer than five years, the subsidized interest
rates generally increase  at smaller  percentage increments for  each year.  The
subsidy  agreements  relating  to  Subsidy  Loans  made  under  a  fixed program
generally will  provide  for  subsidized interest  rates  at  fixed  percentages
(generally  one percentage  point to two  percentage points)  below the Mortgage
Interest Rates for  specified periods,  generally not  in excess  of ten  years.
Subsidy Loans are also offered pursuant to combination fixed/graduated programs.
The subsidy agreements relating to such Subsidy Loans generally will provide for
an  initial fixed  subsidy of  up to  five percentage  points below  the related
Mortgage Interest Rate for up  to five years, and  then a periodic reduction  in
the  subsidy for up to  five years, at an equal  fixed percentage per year until
the subsidized rate equals the Mortgage Interest Rate.
 
    Generally, employers may terminate subsidy programs in the event of (i)  the
mortgagor's  death, retirement,  resignation or termination  of employment, (ii)
the full prepayment  of the Subsidy  Loan by  the mortgagor, (iii)  the sale  or
transfer by the mortgagor of the related Mortgaged Property as a result of which
the  mortgagee  is  entitled to  accelerate  the  Subsidy Loan  pursuant  to the
"due-on-sale" clause  contained in  the Mortgage,  or (iv)  the commencement  of
foreclosure  proceedings or the acceptance of a  deed in lieu of foreclosure. In
addition, some  subsidy programs  provide  that if  prevailing market  rates  of
interest  on mortgage loans similar to a Subsidy Loan are less than the Mortgage
Interest Rate of such Subsidy Loan, the employer may request that the  mortgagor
refinance  such Subsidy Loan and may  terminate the related subsidy agreement if
the mortgagor fails to refinance such  Subsidy Loan. In the event the  mortgagor
refinances  such Subsidy Loan,  the new loan  will not be  included in the Trust
Estate. See "Prepayment and Yield Considerations" herein. In the event a subsidy
agreement is terminated,  the amount remaining  in the Subsidy  Account will  be
returned  to the employer, and the mortgagor  will be obligated to make the full
 
                                       14
<PAGE>
amount of  all remaining  scheduled payments,  if any.  The mortgagor's  reduced
monthly  housing expense as a consequence  of payments under a subsidy agreement
is used  by PHMC  in determining  certain expense-to-income  ratios utilized  in
underwriting a Subsidy Loan. See "PHMC--Mortgage Loan Underwriting."
 
    If  so specified in the applicable Prospectus Supplement, a Trust Estate may
contain Mortgage Loans  subject to temporary  buy-down plans ("Buy-Down  Loans")
pursuant  to which the monthly  payments made by the  mortgagor during the early
years of the Mortgage Loan will be  less than the scheduled monthly payments  on
the  Mortgage Loan. The resulting difference  in payment will be compensated for
from an amount contributed  by the seller of  the related Mortgaged Property  or
another  source, including the  originator of the Mortgage  Loan (generally on a
present value basis) and, if so specified in the related Prospectus  Supplement,
placed  in a  custodial account  (the "Buy-Down Fund")  by the  Servicer. If the
mortgagor on a  Buy-Down Loan  prepays such Mortgage  Loan in  its entirety,  or
defaults on such Mortgage Loan and the Mortgaged Property is sold in liquidation
thereof,  during the period when  the mortgagor is not  obligated, on account of
the buy-down plan, to pay the full  monthly payment otherwise due on such  loan,
the  unpaid  principal balance  of such  Buy-Down  Loan will  be reduced  by the
amounts remaining in the Buy-Down Fund  with respect to such Buy-Down Loan,  and
such  amounts will be deposited in  the Certificate Account (as defined herein),
net of any  amounts paid  with respect  to such  Buy-Down Loan  by any  insurer,
guarantor or other person pursuant to a credit enhancement arrangement described
in the applicable Prospectus Supplement.
 
    If  so specified in the applicable Prospectus Supplement, a Trust Estate may
include Mortgage Loans which are amortized over 30 years but which have  shorter
terms  to maturity (each such  Mortgage Loan, a "Balloon  Loan") that causes the
outstanding principal balance of the related Mortgage Loan to be due and payable
at the  end  of  a  certain specified  period  (the  "Balloon  Period").  Unless
otherwise  specified in  the applicable  Prospectus Supplement,  the borrower of
such Balloon Loan  will be  obligated to  pay the  entire outstanding  principal
balance  of the Balloon  Loan at the end  of the related  Balloon Period. In the
event PHMC refinances a mortgagor's Balloon Loan at maturity, the new loan  will
not  be included in the Trust  Estate. See "Prepayment and Yield Considerations"
herein. A Trust Estate  may also include  other types of  Mortgage Loans to  the
extent set forth in the applicable Prospectus Supplement.
 
  INSURANCE POLICIES
 
    The Pooling and Servicing Agreement will require the Servicer to cause to be
maintained for each Mortgage Loan a standard hazard insurance policy issued by a
generally acceptable insurer insuring the improvements on the Mortgaged Property
underlying  such Mortgage Loan  against loss by fire,  with extended coverage (a
"Standard Hazard Insurance  Policy"). The Pooling  and Servicing Agreement  will
require  that such  Standard Hazard  Insurance Policy be  in an  amount at least
equal to the lesser of  100% of the insurable value  of the improvements on  the
Mortgaged  Property or  the principal balance  of such  Mortgage Loan; provided,
however, that such insurance may not be less than the minimum amount required to
fully compensate  for  any damage  or  loss on  a  replacement cost  basis.  The
Servicer  will also maintain  on property acquired upon  foreclosure, or deed in
lieu of foreclosure, of any Mortgage Loan, a Standard Hazard Insurance Policy in
an amount that is at least equal to the lesser of 100% of the insurable value of
the improvements which are a part of  such property or the principal balance  of
such  Mortgage Loan  plus accrued  interest and  liquidation expenses; provided,
however, that such insurance may not be less than the minimum amount required to
fully compensate for any damage or loss on a replacement cost basis. Any amounts
collected under  any such  policies (other  than amounts  to be  applied to  the
restoration  or repair of the Mortgaged Property  or released to the borrower in
accordance  with  normal  servicing  procedures)   will  be  deposited  in   the
Certificate Account.
 
    The Standard Hazard Insurance Policies covering the Mortgage Loans generally
will  cover  physical damage  to,  or destruction  of,  the improvements  on the
Mortgaged Property caused by fire, lightning, explosion, smoke, windstorm, hail,
riot, strike  and civil  commotion,  subject to  the conditions  and  exclusions
particularized  in each policy.  Because the Standard  Hazard Insurance Policies
relating to such Mortgage Loans will  be underwritten by different insurers  and
will  cover Mortgaged Properties  located in various  states, such policies will
not contain identical terms and conditions. The most significant terms  thereof,
 
                                       15
<PAGE>
however,  generally  will  be determined  by  state  law and  generally  will be
similar. Most  such  policies  typically  will 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  mudflows), nuclear  reaction, wet or  dry rot, vermin,  rodents, insects or
domestic animals,  hazardous  wastes  or hazardous  substances,  theft  and,  in
certain  cases, vandalism.  The foregoing list  is merely  indicative of certain
kinds of uninsured risks and is not all-inclusive.
 
    The Servicer may maintain a blanket policy insuring against hazard losses on
all of the  Mortgaged Properties in  lieu of maintaining  the required  Standard
Hazard  Insurance Policies. The  Servicer will be  liable for the  amount of any
deductible under a blanket policy  if such amount would  have been covered by  a
required Standard Hazard Insurance Policy, had it been maintained.
 
    In  general, if the improvements  on a Mortgaged Property  are located in an
area identified  in the  Federal Register  by the  Federal Emergency  Management
Agency  as having special flood hazards (and  such flood insurance has been made
available) the  Pooling and  Servicing Agreement  will require  the Servicer  to
cause  to be maintained a flood insurance policy meeting the requirements of the
current guidelines  of the  Federal Insurance  Administration with  a  generally
acceptable  insurance carrier.  Generally, the  Pooling and  Servicing Agreement
will require that such flood insurance be  in an amount not less than the  least
of  (i) the outstanding  principal balance of  the Mortgage Loan,  (ii) the full
insurable value of the  improvements, or (iii) the  maximum amount of  insurance
which  is available under the Flood Disaster Protection Act of 1973, as amended.
PHMC does not provide financing for flood zone properties located in communities
not participating  in  the National  Flood  Insurance Program  or  if  available
insurance coverage is, in its judgment, unrealistically low.
 
    Any  losses incurred with  respect to Mortgage Loans  due to uninsured risks
(including earthquakes,  mudflows,  floods  and hazardous  wastes  or  hazardous
substances) or insufficient hazard insurance proceeds could affect distributions
to the Certificateholders.
 
  ACQUISITION OF THE MORTGAGE LOANS FROM PHMC
 
    The  Seller will  have acquired  the Mortgage  Loans included  in each Trust
Estate from PHMC. In connection with the conveyance of the Mortgage Loans to the
Seller, PHMC will (i) agree to deliver to the Seller all of the documents  which
the   Seller  is  required  to  deliver   to  the  Trustee;  (ii)  make  certain
representations and warranties to the Seller which will be the basis of  certain
of  the Seller's representations and warranties  to the Trustee; and (iii) agree
to repurchase or substitute for any Mortgage Loan for which any document is  not
delivered  or is  found to  be defective  in any  material respect,  or which is
discovered at any  time not to  be in conformance  with the representations  and
warranties  PHMC has made to the Seller, if PHMC cannot deliver such document or
cure such defect or breach within  60 days after notice thereof. Such  agreement
will  inure to  the benefit of  the Trustee and  is intended to  help ensure the
Seller's performance of its limited  obligation to repurchase or substitute  for
Mortgage  Loans. See "The Trust  Estates--Mortgage Loans--Assignment of Mortgage
Loans to the Trustee," and "--Representations and Warranties."
 
  ASSIGNMENT OF MORTGAGE LOANS TO THE TRUSTEE
 
    At the time of issuance of  each Series of Certificates, the Mortgage  Loans
in  the  related  Trust Estate  will,  pursuant  to the  applicable  Pooling and
Servicing Agreement, be assigned to the Trustee, together with all principal and
interest received on or with respect to such Mortgage Loans after the applicable
Cut-Off Date other than principal and interest due and payable on or before such
Cut-Off Date  and interest  attributable to  the Fixed  Retained Yield  on  such
Mortgage  Loans, if  any. See "Servicing  of the  Mortgage Loans--Fixed Retained
Yield, Servicing Compensation and Payment of Expenses." The Trustee or its agent
will,  concurrently  with   such  assignment,  authenticate   and  deliver   the
Certificates  evidencing such Series to the  Seller in exchange for the Mortgage
Loans. Each  Mortgage Loan  will be  identified in  a schedule  appearing as  an
exhibit  to the applicable  Pooling and Servicing  Agreement. Each such schedule
will include, among other things, the  unpaid principal balance as of the  close
of  business on the applicable Cut-Off Date,  the maturity date and the Mortgage
Interest Rate for each Mortgage Loan in the related Trust Estate.
 
                                       16
<PAGE>
    In addition,  with respect  to each  Mortgage Loan  in a  Trust Estate,  the
mortgage or other promissory note, any assumption, modification or conversion to
fixed  interest rate agreement, a mortgage assignment in recordable form and the
recorded Mortgage (or other  documents as are required  under applicable law  to
create  a perfected security interest in the  Mortgaged Property in favor of the
Trustee) will  be delivered  to  the Trustee  (or  to a  designated  custodian);
provided  that, in instances where recorded documents cannot be delivered due to
delays in connection with recording, copies thereof, certified by the Seller  to
be  true  and complete  copies  of such  documents  sent for  recording,  may be
delivered and the original  recorded documents will  be delivered promptly  upon
receipt. As to each Mortgage Loan for which there is primary mortgage insurance,
the  certificate of primary mortgage insurance will be delivered to the Trustee.
The assignment of  each Mortgage  will be  recorded promptly  after the  initial
issuance  of Certificates for the related  Trust Estate, except in states where,
in the  opinion of  counsel acceptable  to the  Trustee, such  recording is  not
required  to protect  the Trustee's  interest in  the Mortgage  Loan against the
claim of  any subsequent  transferee or  any  successor to  or creditor  of  the
Seller, PHMC or the originator of such Mortgage Loan.
 
    The   Trustee  will  hold  such  documents  in  trust  for  the  benefit  of
Certificateholders of the related Series  and will review such documents  within
45  days of the date  of the applicable Pooling  and Servicing Agreement. If any
document is not delivered or is found  to be defective in any material  respect,
or  if the  Seller is  in breach  of any  of its  representations and warranties
contained in such Pooling  and Servicing Agreement,  and such breach  materially
and  adversely affects  the interests  of the  Certificateholders in  a Mortgage
Loan, and the Seller cannot deliver such document or cure such defect or  breach
within  60 days after written notice thereof, the Seller will, within 60 days of
such notice, either repurchase the related  Mortgage Loan from the Trustee at  a
price  equal  to the  then unpaid  principal balance  thereof, plus  accrued and
unpaid interest  at  the applicable  Mortgage  Interest Rate  (minus  any  Fixed
Retained Yield) through the last day of the month in which such repurchase takes
place,  or (in the  case of a  Series for which  a REMIC election  will be made,
unless the  maximum  period  as  may  be provided  by  the  Code  or  applicable
regulations  of the  Department of  the Treasury  ("Treasury Regulations") shall
have elapsed  since  the  execution  of the  applicable  Pooling  and  Servicing
Agreement)  substitute  for  such  Mortgage  Loan  a  new  mortgage  loan having
characteristics such that the representations and warranties of the Seller  made
pursuant   to  the  applicable  Pooling  and  Servicing  Agreement  (except  for
representations and warranties as to the correctness of the applicable  schedule
of  mortgage loans) would  not have been incorrect  had such substitute Mortgage
Loan originally been  a Mortgage  Loan. In the  case of  a repurchased  Mortgage
Loan,  the  purchase  price will  be  deposited  by the  Seller  in  the related
Certificate Account. In  the case of  a substitute Mortgage  Loan, the  mortgage
file  relating thereto will be  delivered to the Trustee  (or the custodian) and
the Seller will deposit in the Certificate Account an amount equal to the excess
of (i) the unpaid  principal balance of the  Mortgage Loan which is  substituted
for,  over (ii)  the unpaid principal  balance of the  substitute Mortgage Loan,
together with interest on such excess at  the Net Mortgage Interest Rate to  the
next  scheduled Due  Date of  the Mortgage Loan  which is  being substituted for
(adjusted, in the case of a Series for  which a REMIC election will be made,  as
set  forth in the applicable Pooling and Servicing Agreement, to ensure that the
Trustee will not recognize gain). In no event will any substitute Mortgage  Loan
have  an unpaid principal  balance greater than  the Scheduled Principal Balance
(as defined herein)  of the  Mortgage Loan for  which it  is substituted  (after
giving   effect  to  the  scheduled  principal  payment  due  in  the  month  of
substitution on the Mortgage  Loan substituted for), or  a term greater than,  a
Mortgage Interest Rate less than, a Mortgage Interest Rate more than one percent
per  annum greater than or  a Loan-to-Value greater than,  the Mortgage Loan for
which it is substituted. If  substitution is to be  made for an adjustable  rate
Mortgage  Loan,  the  substitute Mortgage  Loan  will have  an  unpaid principal
balance no greater than the Scheduled Principal Balance of the Mortgage Loan for
which it is substituted (after giving effect to the scheduled principal  payment
due  in  the month  of substitution  on  the Mortgage  Loan substituted  for), a
Loan-to-Value Ratio less than or equal to, and a Mortgage Interest Rate at least
equal to, that of the Mortgage Loan  for which it is substituted, and will  bear
interest  based on  the same  index, margin and  frequency of  adjustment as the
substituted  Mortgage  Loan.  Unless  otherwise  specified  in  the   applicable
Prospectus  Supplement, the repurchase obligation  and the mortgage substitution
referred  to  above  will  constitute   the  sole  remedies  available  to   the
Certificateholders or the Trustee with respect to
 
                                       17
<PAGE>
missing  or defective  documents or breach  of the  Seller's representations and
warranties. Notwithstanding the above, if an election is made to treat the Trust
Estate (or a  segregated pool of  assets therein)  with respect to  a Series  of
Certificates  as  a  REMIC  (see  "Certain  Federal  Income  Tax Consequences"),
substitutions will be made  only upon receipt  by the Trustee  of an opinion  of
counsel  or other evidence satisfactory  to the Trustee to  the effect that such
substitution will not cause the Trust  Estate (or segregated pool of assets)  to
be  subject  to the  tax on  "prohibited transactions"  imposed by  Code Section
860F(a), otherwise subject the  Trust Estate (or segregated  pool of assets)  to
tax,  cause any replacement mortgage not  to constitute a "qualified replacement
mortgage" within the  meaning of  Code Section  860G(a)(4), or  cause the  Trust
Estate  (or segregated pool of  assets) to fail to qualify  as a REMIC. See "The
Trust Estates--Mortgage Loans" with  respect to certain  obligations of PHMC  in
connection  with  defective documentation  and  breaches of  representations and
warranties as to the Mortgage Loans.
 
    The Trustee will be authorized to appoint a custodian to maintain possession
of the documents relating  to the Mortgage  Loans and to  conduct the review  of
such  documents  described  above.  The  custodian  will  keep  and  review such
documents as the Trustee's agent under a custodial agreement.
 
  REPRESENTATIONS AND WARRANTIES
 
    Unless otherwise provided in the applicable Pooling and Servicing  Agreement
for  a Series, the Seller will represent and warrant to the Trustee, among other
things, that as of the date of execution of the Pooling and Servicing Agreement,
with respect to the Mortgage Loans, or each Mortgage Loan, as the case may be:
 
        (i)   the  information set  forth  in  the schedule  of  Mortgage  Loans

    information is furnished as specified therein;
 
        (ii)  immediately prior to  the transfer and  assignment contemplated by
    the Pooling and Servicing Agreement, the Seller is the sole owner and holder

    or security interests of any nature and has full right and authority to sell
    and assign the same;
 
        (iii)  the Mortgage is a valid, subsisting and enforceable first lien on
    the related Mortgaged Property, and the Mortgaged Property is free and clear

    yet
    due and payable and liens or interests  arising under or as a result of  any
    federal,  state or local law, regulation  or ordinance relating to hazardous
    wastes or  hazardous  substances;  and,  if  the  Mortgaged  Property  is  a
    condominium  unit, any lien for common charges permitted by statute; and any
    security agreement, chattel mortgage or equivalent document related to,  and

    valid first lien on the property  described therein and the Seller has  full
    right to sell and assign the same to the Trustee;
 
        (iv)  neither the  Seller nor  any prior holder  of the  Mortgage or the
    related Mortgage Note  has modified  the Mortgage in  any material  respect;
    satisfied,  cancelled or subordinated  the Mortgage or  the related Mortgage
    Note in whole or in part; or released the Mortgaged Property in whole or  in
    part  from the lien of the Mortgage;  or executed any instrument of release,

    Seller  has not advanced funds  or received any advance  of funds by a party
    other than the  mortgagor, directly  or indirectly (except  pursuant to  any
    Buy-Down  Loan or Subsidy  Loan arrangement), for the  payment of any amount
    required by the Mortgage, except for interest accruing from the date of  the
    related Mortgage Note or date of disbursement of the Mortgage Loan proceeds,
    whichever is later, to the date which precedes by 30 days the first Due Date
    under the related Mortgage Note;
 
                                       18

        (vi)  to  the best  of the  Seller's knowledge,  there is  no proceeding
    pending or threatened for the total or partial condemnation of the Mortgaged
    Property and the Mortgaged Property is undamaged by water, fire,  earthquake
    or  earth movement, windstorm, flood, tornado or similar casualty (excluding
    casualty from the presence of  hazardous wastes or hazardous substances,  as
    to  which the Seller makes no representation), so as to affect adversely the
    value of the Mortgaged Property as security for the Mortgage Loan or the use
    for which the premises were intended;
 
        (vii) the Mortgaged  Property is free  and clear of  all mechanics'  and
    materialmen's  liens or liens in the nature thereof; provided, however, that
    this warranty shall  be deemed  not to  have been made  at the  time of  the

    received)  is covered by  an ALTA mortgagee title  insurance policy or other
    generally
 
                                       19
<PAGE>
    acceptable form of policy or insurance  acceptable to FNMA or FHLMC,  issued
    by  a title insurer acceptable to FNMA or FHLMC insuring the originator, its
    successors and assigns, as to the first priority lien of the Mortgage in the
    original principal amount of the Mortgage  Loan and subject only to (A)  the
    lien of current real property taxes and assessments not yet due and payable,
    (B)  covenants,  conditions and  restrictions, rights-of-way,  easements and
    other matters of public record as of the date of recording of such  Mortgage
    acceptable  to  mortgage  lending  institutions in  the  area  in  which the

    performed  in connection with the origination  of the related Mortgage Loan,
    (C) liens created pursuant to any federal, state or local law, regulation or
    ordinance affording liens for the costs of clean-up of hazardous  substances
    or  hazardous wastes or for other  environmental protection purposes and (D)
    such other matters to  which like properties are  commonly subject which  do
    not  individually,  or  in  the  aggregate,  materially  interfere  with the
    benefits of the security intended to be provided by the Mortgage; the Seller
    is the sole insured of such mortgagee title insurance policy, the assignment
    to the Trustee of  the Seller's interest in  such mortgagee title  insurance
    policy  does not require any consent of or notification to the insurer which
    has not been obtained or made,  such mortgagee title insurance policy is  in
    full  force and effect and will be in full force and effect and inure to the
    benefit of the  Trustee and no  claims have been  made under such  mortgagee
    title  insurance  policy,  and  no prior  holder  of  the  related Mortgage,

    as are covered under a standard extended coverage endorsement, in an  amount
    which  is not  less than the  lesser of 100%  of the insurable  value of the
    Mortgaged Property and  the outstanding  principal balance  of the  Mortgage
    Loan,  but  in no  event less  than  the minimum  amount necessary  to fully
    compensate for  any damage  or loss  on  a replacement  cost basis;  if  the
    Mortgaged  Property is a condominium unit, it is included under the coverage
    afforded by a  blanket policy for  the project; if  upon origination of  the
    Mortgage  Loan, the improvements  on the Mortgaged Property  were in an area
    identified in  the  Federal Register  by  the Federal  Emergency  Management
    Agency as having special flood hazards, a flood insurance policy meeting the
    requirements   of   the  current   guidelines   of  the   Federal  Insurance
    Administration is in effect with  a generally acceptable insurance  carrier,
    in  an  amount representing  coverage not  less  than the  least of  (A) the
    outstanding principal balance of the  Mortgage Loan, (B) the full  insurable
    value  and (C) the maximum amount of insurance which was available under the
    Flood Disaster  Protection Act  of  1973; and  each Mortgage  obligates  the
    mortgagor  thereunder to maintain all such insurance at the mortgagor's cost
    and expense;
 
        (xvii) to  the best  of the  Seller's knowledge,  there is  no  default,
    breach,  violation or event  of acceleration existing  under any Mortgage or
    the related Mortgage Note and  no event which, with  the passage of time  or
    with notice and the expiration of any grace or cure period, would constitute
    a  default, breach, violation  or event of acceleration;  and the Seller has
    not waived  any default,  breach,  violation or  event of  acceleration;  no
    foreclosure  action is threatened or has  been commenced with respect to the
    Mortgage Loan;
 
        (xviii) no  Mortgage  Note  or  Mortgage is  subject  to  any  right  of
    rescission,  set-off,  counterclaim  or defense,  including  the  defense of
    usury, nor will the operation  of any of the terms  of the Mortgage Note  or
    Mortgage,  or the  exercise of  any right  thereunder, render  such Mortgage
    unenforceable, in  whole  or  in  part,  or  subject  it  to  any  right  of
    rescission,  set-off,  counterclaim  or defense,  including  the  defense of
    usury, and no such right of rescission, set-off, counterclaim or defense has
    been asserted with respect thereto;
 
        (xix) each Mortgage Note  is payable in  monthly payments, resulting  in
    complete  amortization of the Mortgage Loan over a term of not more than 360
    months;
 
        (xx) each Mortgage contains customary and enforceable provisions such as
    to render the  rights and remedies  of the holder  thereof adequate for  the
    realization against the Mortgaged Property of the
 
                                       20
<PAGE>
    benefits  of  the security,  including  realization by  judicial foreclosure
    (subject to any limitation arising from any bankruptcy, insolvency or  other
    law for the relief of debtors), and there is no homestead or other exemption
    available  to  the  mortgagor  which  would  interfere  with  such  right of
    foreclosure;
 
        (xxi) to the best of the Seller's knowledge, no mortgagor is a debtor in
    any state or federal bankruptcy or insolvency proceeding;
 
        (xxii) each  Mortgaged Property  is  located in  the United  States  and
    consists of a one- to four-unit single family residential property which may
    include a detached home, townhouse, condominium unit, unit in a planned unit
    development or a leasehold interest with respect to any of the foregoing or,
    in  the case of Mortgage Loans secured  by shares of cooperatives, leases or
    occupancy agreements;
 
        (xxiii) no payment required under any Mortgage Loan is more than 30 days
    past due and no Mortgage Loan had more than one delinquency in the preceding
    13 months; and
 
        (xxiv) with respect to  each Buy-Down Loan, the  funds deposited in  the
    Buy-Down Fund, if any, will be sufficient, together with interest thereon at
    the  rate  customarily  received by  the  Seller on  such  funds, compounded
    monthly, and adding  the amounts required  to be paid  by the mortgagor,  to
    make  the scheduled payments stated in the Mortgage Note for the term of the
    buy-down agreement.
 
    No representations or warranties are made by the Seller as to the absence or
effect of  hazardous wastes  or hazardous  substances on  any of  the  Mortgaged
Properties  or on the lien of any  Mortgage, and any loss or liability resulting
from the presence  or effect of  such hazardous wastes  or hazardous  substances
will  be borne solely  by Certificateholders. See "Certain  Legal Aspects of the
Mortgage Loans--Environmental Considerations" below.
 
    See "The Trust  Estates--Mortgage Loans"  for a description  of the  limited
remedies  available in connection with breaches of the foregoing representations
and warranties.
 
  OPTIONAL REPURCHASES
 
    The Seller may, at its option, repurchase any defaulted Mortgage Loan if, in
the Seller's judgment,  the related default  is not  likely to be  cured by  the
borrower,  at a price equal to the unpaid principal balance thereof plus accrued
interest thereon and under the conditions set forth in the applicable Prospectus
Supplement.
 
                        DESCRIPTION OF THE CERTIFICATES
 
GENERAL
 
    Each Series  of  Certificates will  be  issued  pursuant to  a  Pooling  and
Servicing  Agreement (the "Pooling and Servicing Agreement") between the Seller,
the Servicer, and  the Trustee  named in the  applicable Prospectus  Supplement.
Each  Pooling and Servicing Agreement will  contain substantially the same terms
and conditions, except  for revisions  of defined terms  and certain  provisions
regarding  distributions to Certificateholders, credit support and other similar
matters. Illustrative forms of Pooling  and Servicing Agreement have been  filed
as  exhibits to the Registration  Statement of which this  Prospectus is a part.
The following summaries describe certain  provisions common to the  Certificates
and  to each Pooling and Servicing Agreement. The summaries do not purport to be
complete and are subject  to, and are qualified  in their entirety by  reference
to, all of the provisions of the Pooling and Servicing Agreement for each Series
of  Certificates and  the applicable Prospectus  Supplement. Wherever particular
sections or defined terms  of the Pooling and  Servicing Agreement are  referred
to,  such sections or defined terms are thereby incorporated herein by reference
from the  forms of  Pooling and  Servicing Agreement  filed as  exhibits to  the
Registration Statement.
 
    Each  Series  of  Certificates  will represent  ownership  interests  in the
related Trust Estate. An election  may be made to treat  the Trust Estate (or  a
segregated pool of assets therein) with respect to a Series of Certificates as a
REMIC.  If such  an election is  made, such Series  will consist of  one or more
Classes of  Certificates  that will  represent  "regular interests"  within  the
meaning of Code Section 860G(a)(1) (such
 
                                       21
<PAGE>
Class or Classes collectively referred to as the "Regular Certificates") and one
Class  or  Subclass of  Certificates with  respect  to each  REMIC that  will be
designated as "residual interests" within the meaning of Code Section 860G(a)(2)
(the "Residual Certificates") representing the right to receive distributions as
specified in the  Prospectus Supplement  for such Series.  See "Certain  Federal
Income Tax Consequences" herein.
 
    The  Seller may sell certain Classes or  Subclasses of the Certificates of a
Series, including one or more Classes of Subordinated Certificates, in privately
negotiated transactions  exempt  from  registration under  the  Securities  Act.
Alternatively,  if  so specified  in a  Prospectus  Supplement relating  to such
Subordinated Certificates,  the Seller  may offer  one or  more Classes  of  the
Subordinated  Certificates  of a  Series by  means of  this Prospectus  and such
Prospectus Supplement.
 
    Unless otherwise  specified in  the  applicable Prospectus  Supplement  with
respect  to a Series of Certificates, each Certificate offered hereby and by the
applicable Prospectus Supplement will  be issued in  fully registered form.  The
Certificates  of  a  Series  offered  hereby  and  by  means  of  the applicable
Prospectus Supplements will be  transferable and exchangeable  at the office  or
agency maintained by the Trustee or such other entity for such purpose set forth
in  the related Prospectus  Supplement. No service  charge will be  made for any
transfer or exchange of Certificates, but  the Trustee or such other entity  may
require  payment of  a sum  sufficient to  cover any  tax or  other governmental
charge in  connection with  such transfer  or  exchange. In  the event  that  an
election  is made  to treat  the Trust  Estate (or  a segregated  pool of assets
therein) as a REMIC, no  legal or beneficial interest in  all or any portion  of
the  "residual interest" thereof  may be transferred without  the receipt by the
transferor of an affidavit signed by the transferee stating that the  transferee
is not a disqualified organization within the meaning of Code Section 860E(e) or
an  agent (including  a broker, nominee,  or middleman) thereof  or a Book-Entry
Nominee   (as    defined   herein).    See   "Certain    Federal   Income    Tax
Consequences--Federal  Income Tax Consequences for REMIC Certificates-- Taxation
of Residual  Certificates--Tax-Related  Restrictions  on  Transfer  of  Residual
Certificates."  In the  event that an  election is  not made to  treat the Trust
Estate (or a  segregated pool  of assets therein)  as a  REMIC, no  Subordinated
Certificate  may be  transferred unless  an appropriate  ruling of  the Internal
Revenue Service  or  opinion of  counsel  is obtained  to  the effect  that  the
transfer  will not result in the  arrangement contemplated under the Pooling and
Servicing Agreement being  treated as  an association taxable  as a  corporation
under the Code.
 
    Unless   otherwise  specified  in   the  applicable  Prospectus  Supplement,
distributions  to  Certificateholders  of  all  Series  (other  than  the  final
distribution  in retirement of the Certificates) will be made by check mailed to
the address of  the person  entitled thereto as  it appears  on the  certificate
register,  except that, with  respect to any holder  of a Certificate evidencing
not less  than  a certain  minimum  denomination  set forth  in  the  applicable
Prospectus   Supplement,  distributions  will  be   made  by  wire  transfer  in
immediately available funds,  provided that  the Servicer, or  the Paying  Agent
acting  on behalf  of the Servicer,  shall have been  furnished with appropriate
wiring instructions  not less  than three  business days  prior to  the  related
Distribution  Date. The final distribution in retirement of Certificates will be
made only upon presentation and surrender  of the Certificates at the office  or
agency  maintained by the Trustee or other entity for such purpose, as specified
in the final distribution notice to Certificateholders.
 
    A Series of  Certificates will consist  of one or  more Classes of  Standard
Certificates   or  Stripped  Certificates  (referred  to  hereinafter  sometimes
collectively as "Percentage Certificates") or two or more Classes of Multi-Class
Certificates (each as described below).
 
PERCENTAGE CERTIFICATES
 
    Each Series of Percentage  Certificates may include one  or more Classes  of
Standard  Certificates  or  Stripped Certificates,  any  Class of  which  may be
divided into two  or more Subclasses.  The Standard Certificates  of each  Class
will  evidence  fractional  undivided  interests in  all  of  the  principal and
interest (to  the extent  of the  Net Mortgage  Interest Rate)  payments on  the
Mortgage  Loans comprising the Trust Estate  related to such Series. Each holder
of  a  Standard  Certificate  of  a  Class  will  be  entitled  to  receive  its
Certificate's percentage interest of the portion of the Pool Distribution Amount
(as  defined below)  allocated to  such Class.  The percentage  interest of each
Standard   Certificate   will    be   equal   to    the   percentage    obtained
 
                                       22
<PAGE>
by  dividing  the  aggregate  unpaid principal  balance  of  the  Mortgage Loans
represented by such Standard Certificate as of the Cut-Off Date by the aggregate
unpaid principal balance of the Mortgage  Loans represented by all the  Standard
Certificates of the same Class as of the Cut-Off Date.
 
    The  Stripped Certificates of each  Class will evidence fractional undivided
interests in specified portions of the principal and/or interest payments on the
Mortgage Loans comprising the Trust Estate  related to such Series. The  holders
of the Stripped Certificates of each Class will be entitled to receive a portion
(which  may be zero) as specified in the applicable Prospectus Supplement of the
principal distributions comprising the Pool  Distribution Amount, and a  portion
(which  may be zero) as specified in the applicable Prospectus Supplement of the
interest  distributions  comprising  the   Pool  Distribution  Amount  on   each
Distribution Date.
 
    In  the case of  Classes of Stripped  Certificates representing interests in
interest distributions on the Mortgage Loans and not in principal  distributions
on  the  Mortgage  Loans,  such Certificates  will  be  denominated  in notional
amounts. The aggregate original notional amount for a Class of such Certificates
will be equal to the aggregate unpaid principal balance (or a specified  portion
thereof)  of  the  Mortgage  Loans  as of  the  Cut-Off  Date  specified  in the
applicable Prospectus  Supplement. The  notional amount  of each  such  Stripped
Certificate  will  be used  to  calculate the  holder's  pro rata  share  of the
interest distributions on the Mortgage Loans allocated to that Class and for the
determination of  certain other  rights of  holders of  such Class  of  Stripped
Certificates  and will not represent an interest  in, or entitle any such holder
to any distribution with respect to, any principal distributions on the Mortgage
Loans. Each such Certificate's  pro rata share of  the interest distribution  on
the  Mortgage Loans on each Distribution  Date will be calculated by multiplying
the interest distributions  on the Mortgage  Loans allocated to  its Class by  a
fraction,  the  numerator  of which  is  the  original notional  amount  of such
Stripped Certificate  and the  denominator of  which is  the aggregate  original
notional amount of all the Stripped Certificates of its Class.
 
    The  interest of a Class of Percentage Certificates representing an interest
in a Trust Estate (or a segregated pool of assets therein) with respect to which
an election to be  treated as a REMIC  has been made may  be fixed as  described
above  or may  vary over  time as  a result  of prepayments  received and losses
realized on the underlying Mortgage  Loans. A Series of Percentage  Certificates
comprised  of Classes whose percentage interests in the Trust Estate may vary is
referred  to  herein   as  a   Series  of   "Shifting  Interest   Certificates."
Distributions  on,  and  subordination arrangements  with  respect  to, Shifting
Interest Certificates are discussed below under the headings "Description of the
Certificates--Distributions to Percentage Certificateholders--Shifting  Interest
Certificates" and "Credit Support--Subordination--Shifting Interest
Certificates."
 
MULTI-CLASS CERTIFICATES
 
    Each  Series may  include two or  more Classes  of Multi-Class Certificates.
Each Multi-Class Certificate will be assigned a Stated Amount. The Stated Amount
may be based on an  amount of principal of the  underlying Mortgage Loans or  on
the  value of  an amount  of future  cash flows  from the  related Trust Estate,
without distinction as to principal and interest received on the Mortgage Loans.
The initial  Stated  Amount  of  each  Class  within  a  Series  of  Multi-Class
Certificates will be specified in the applicable Prospectus Supplement. Interest
on the Classes of Multi-Class Certificates will be paid at rates specified in or
determined as specified in the applicable Prospectus Supplement, and will accrue
in  the manner  specified therein. Each  Series of  Multi-Class Certificates may
include one or more Classes of Certificates on which interest accrues but is not
payable until such  time as  specified in the  applicable Prospectus  Supplement
("Compound  Interest Certificates"), and interest accrued on any such Class will
be added to the Stated Amount thereof in the manner described therein.
 
DISTRIBUTIONS TO PERCENTAGE CERTIFICATEHOLDERS
 
  CERTIFICATES OTHER THAN SHIFTING INTEREST CERTIFICATES
 
    Except as otherwise specified in the applicable Prospectus Supplement, on or
about the  17th day  of each  month in  which a  Distribution Date  occurs  (the
"Determination  Date"), the Servicer will determine  the amount of the principal
and interest payments on the Mortgage Loans which will be distributed to holders
of each  Class  and  Subclass  of  Percentage  Certificates  on  the  succeeding
Distribution Date. Such amounts will
 
                                       23
<PAGE>
be  distributed,  pro rata,  to holders  of  a Class  or Subclass  of Percentage
Certificates (other than Shifting Interest Certificates) except, in the case  of
Subordinated  Certificateholders, for  any amounts  required to  be paid  to the
holders  of  the  related  Senior  Certificates  or  deposited  in  the  related
Subordination  Reserve Fund, if any. If the  Certificates of a Class include two
or more Subclasses, the  allocation of distributions  of principal and  interest
among such Subclasses will be as specified in the related Prospectus Supplement.
 
    CALCULATION  OF  DISTRIBUTABLE AMOUNTS.    On each  Determination  Date, the
Servicer  will   calculate  the   "Distributable  Amount"   for  the   following
Distribution  Date for each Class of Certificates. Unless otherwise specified in
the applicable Prospectus Supplement,  the Distributable Amount  for a Class  of
Senior  Certificates (a "Senior Class") of a  Series on a Distribution Date (the
"Senior Class Distributable Amount") will be an amount equal to the sum of:
 
         (i) the aggregate  undivided interest,  expressed as  a percentage  and
    specified   in  the  applicable  Prospectus  Supplement,  evidenced  by  all
    Certificates of such Senior Class (the "Senior Class Principal Portion") of:
 
           (a) all scheduled payments of principal on each outstanding  Mortgage
       Loan  that  became  due  on  the  Due  Date  immediately  preceding  such
       Distribution Date in  accordance with the  amortization schedules of  the
       related  Mortgage  Loans  (as adjusted  to  give effect  to  any previous
       prepayments), whether or not such payments were actually received by  the
       Servicer  (the aggregate of  such scheduled payments due  on any such Due
       Date being referred to herein as "Scheduled Principal"), and all  partial
       principal  prepayments applied by the Servicer in reduction of the unpaid
       principal balance of any Mortgage Loan on or after the Determination Date
       in the month preceding  the month in which  the Distribution Date  occurs
       (or  after the Cut-Off Date, in the  case of the first Distribution Date)
       and prior to the Determination Date  occurring in the month in which  the
       Distribution Date occurs ("Curtailments");
 
           (b) all principal prepayments in full received by the Servicer during
       the month preceding the month in which such Distribution Date occurs; and
 
           (c)  the  unpaid principal  balance,  less any  amounts  with respect
       thereto constituting Late  Payments (as herein  defined) attributable  to
       principal,  and  less  any unreimbursed  Periodic  Advances  with respect
       thereto, of each  Mortgage Loan which  was repurchased by  the Seller  or
       purchased by the Servicer, as the case may be (as described in "The Trust
       Estates--Mortgage  Loans--Assignment of  Mortgage Loans  to the Trustee",
       "--Optional   Repurchases,"    and    "The    Pooling    and    Servicing
       Agreement--Termination;  Purchase of Certificates"), and of each Mortgage
       Loan in respect of which property was acquired, liquidated or foreclosed,
       and with respect to which  Liquidation Proceeds (as defined herein)  were
       received, during the month preceding the month in which such Distribution
       Date  occurs,  determined as  of  the date  each  such Mortgage  Loan was
       repurchased or purchased, as the case may be, or as of the date each such
       related property was acquired, liquidated or foreclosed, as the case  may
       be; and
 
        (ii)  interest  at  the  applicable Pass-Through  Rate  from  the second
    preceding Due Date to the  Due Date immediately preceding such  Distribution
    Date  on  the  Senior Class  Principal  Portion of  the  aggregate principal
    balance of  the  Mortgage Loans  as  of  the Cut-Off  Date,  less  scheduled
    amortization of principal thereon and any principal prepayments with respect
    thereto  through  the second  preceding Due  Date (the  "Scheduled Principal
    Balance"), whether  or  not  such  interest was  actually  received  by  the
    Servicer;  provided that interest attributable to the accrual of interest on
    any prepaid or liquidated  Mortgage Loan at the  Net Mortgage Interest  Rate
    for  such  Mortgage  Loan  from  the  date  of  its  prepayment  in  full or
    liquidation through the last  day of the month  in which such prepayment  in
    full  or liquidation occurred ("Prepayment  Interest Shortfall") is included
    only to the extent  that funds for  such purposes are  available out of  the
    aggregate   Servicing  Fees   and,  provided   further,  that   interest  on
    Curtailments applied other than on a Due Date, at the Net Mortgage  Interest
    Rate  for the related Mortgage Loan from the date of application through the
    end of the month in which applied ("Curtailment Interest Shortfall"), is not
    included; and
 
                                       24
<PAGE>
        (iii) the sum of (a) the portion  that was included in the Senior  Class
    Distributable  Amount on  a prior  Distribution Date  of the  amount of each
    scheduled payment of principal and interest  on a Mortgage Loan not paid  by
    the  mortgagor  when  due, net  of  any unreimbursed  Periodic  Advance with
    respect thereto that was included in the Distributable Amount of each  Class
    on  a prior Distribution Date but was  not included in the Pool Distribution
    Amount until  the  current  Distribution  Date (such  net  amount,  a  "Late
    Payment"),  less the  aggregate amount, if  any, received by  the holders of
    such Senior  Certificates  on any  prior  Distribution Date  or  Dates  with
    respect  to such  Late Payment from  amounts otherwise  distributable to the
    holders  of  Subordinated  Certificates  and  from  any  credit  enhancement
    available for the benefit of the Senior Certificateholders, and (b) interest
    on  the amount set forth  in clause (a) above  at the Pass-Through Rate from
    the Distribution Date on which such  Late Payment was first included in  the
    Distributable   Amount  for   such  Senior   Certificates  to   the  current
    Distribution Date (the "Late Payment  Period"); provided that the  foregoing
    amount  will  be included  in  the Senior  Class  Distributable Amount  on a
    Distribution Date only  to the extent  such amount is  included in the  Pool
    Distribution Amount with respect to such Distribution Date.
 
    Unless  otherwise  specified in  the  applicable Prospectus  Supplement, the
Distributable Amount for a Class of  Subordinated Certificates of a Series on  a
Distribution  Date (the  "Subordinated Class  Distributable Amount")  will be an
amount equal to the sum of:
 
         (i) the aggregate  undivided interest,  expressed as  a percentage  and
    specified   in  the  applicable  Prospectus  Supplement,  evidenced  by  all
    Subordinated Certificates (the "Subordinated Class Principal Portion") of:
 
           (a) all Scheduled Principal and all Curtailments;
 
           (b) all principal prepayments in full received by the Servicer during
       the month preceding the month in which such Distribution Date occurs; and
 
           (c) the  unpaid  principal balance,  less  any amounts  with  respect
       thereto  constituting Late  Payments attributable to  principal, and less
       any unreimbursed Periodic Advances with respect thereto, of each Mortgage
       Loan which was repurchased  by the Seller or  purchased by the  Servicer,
       and  of each  Mortgage Loan  in respect  of which  property was acquired,
       liquidated or foreclosed, and with respect to which Liquidation  Proceeds
       were  received,  during  the  month preceding  the  month  in  which such
       Distribution Date occurs, determined  as of the  date each such  Mortgage
       Loan  was repurchased or purchased, as the case may be, or as of the date
       each such related property was acquired, liquidated or foreclosed, as the
       case may be; and
 
        (ii) interest  at  the  applicable Pass-Through  Rate  from  the  second
    preceding  Due Date to the Due  Date immediately preceding such Distribution
    Date on the Subordinated Class Principal Portion of the Scheduled  Principal
    Balance  of the Mortgage  Loans as of the  Determination Date preceding such
    Distribution Date, whether or not  such interest was actually received  with
    respect  to the Mortgage Loans;  provided that Prepayment Interest Shortfall
    is included only to  the extent that funds  for such purposes are  available
    from  the aggregate Servicing  Fees and, provided  further, that Curtailment
    Interest Shortfall is not included; and
 
        (iii) the  sum  of  (a) each  Late  Payment  that was  included  in  the
    Subordinated  Class Distributable Amount  on a prior  Distribution Date plus
    the aggregate amount, if any,  received by the Senior Certificateholders  on
    any  prior Distribution Date or Dates with respect to such Late Payment from
    amounts  otherwise   available   for  distribution   to   the   Subordinated
    Certificateholders  on such  prior Distribution Date  or Dates,  or from the
    Subordination Reserve Fund and not attributable to the Initial Deposit,  and
    (b) interest on the amount set forth in clause (a) above at the Pass-Through
    Rate during the Late Payment Period; provided that the foregoing amount will
    be   included  in  the  Subordinated  Class  Distributable  Amount  on  such
    Distribution Date only  to the extent  such amount is  included in the  Pool
    Distribution Amount with respect to such Distribution Date.
 
                                       25
<PAGE>
    DETERMINATION  OF AMOUNTS TO BE DISTRIBUTED.   Unless otherwise specified in
the applicable  Prospectus  Supplement,  funds  available  for  distribution  to
Certificateholders  of a Series of Percentage  Certificates with respect to each
Distribution Date for such Series (the  "Pool Distribution Amount") will be  the
sum  of all  previously undistributed payments  or other receipts  on account of
principal (including principal prepayments and Liquidation Proceeds, if any) and
interest on or in respect of the related Mortgage Loans received by the Servicer
after the Cut-Off Date (except for amounts due on or prior to the Cut-Off Date),
or received by the Servicer  on or prior to the  Cut-Off Date but due after  the
Cut-Off  Date, in either case received on  or prior to the Determination Date in
the month in  which such Distribution  Date occurs, plus  all Periodic  Advances
made by the Servicer with respect to payments due to be received on the Mortgage
Loans  on  the Due  Date  preceding such  Distribution  Date, but  excluding the
following:
 
        (a)  amounts  received  as  late  payments  of  principal  or   interest
    respecting  which the Servicer previously has  made one or more unreimbursed
    Periodic Advances;
 
        (b) unreimbursed Periodic Advances  with respect to liquidated  Mortgage
    Loans;
 
        (c)  those portions of each payment of interest on a particular Mortgage
    Loan which represent  (i) the  Fixed Retained Yield,  if any,  and (ii)  the
    applicable Servicing Fee, as adjusted in respect of principal prepayments in
    full  and Liquidation  Proceeds as described  in "Servicing  of the Mortgage
    Loans--Adjustment to Servicing Fee in Connection with Prepaid and Liquidated
    Mortgage Loans" below;
 
        (d)  all  amounts  representing  scheduled  payments  of  principal  and
    interest  due  after the  Due  Date occurring  in  the month  in  which such
    Distribution Date occurs;
 
        (e) all  principal  prepayments  in full  and  all  proceeds  (including
    Liquidation Proceeds) of any Mortgage Loans, or property acquired in respect
    thereof,  liquidated, foreclosed,  purchased or repurchased  pursuant to the
    applicable Pooling and  Servicing Agreement,  received on or  after the  Due
    Date  occurring in the month in which  such Distribution Date occurs and all
    Curtailments applied  by the  Servicer on  or after  the Determination  Date
    occurring  in  the month  in which  such Distribution  Date occurs,  and all
    related payments of interest on such amounts;
 
        (f)  that portion  of Liquidation Proceeds  which represents any  unpaid
    Servicing  Fee  to  which the  Servicer  is  entitled and  any  unpaid Fixed
    Retained Yield;
 
        (g) if an election has been made to treat the applicable Trust Estate as
    a REMIC, any Net Foreclosure Profits with respect to such Distribution Date.
    "Net Foreclosure Profits" with  respect to a Distribution  Date will be  the
    excess  of  (i)  the portion  of  aggregate net  Liquidation  Proceeds which
    represents the amount by  which aggregate profits  on Liquidated Loans  with
    respect  to  which  net  Liquidation Proceeds  exceed  the  unpaid principal
    balance thereof plus accrued interest thereon at the Mortgage Interest  Rate
    over  (ii) aggregate  realized losses  on Liquidated  Loans with  respect to
    which net Liquidation Proceeds  are less than  the unpaid principal  balance
    thereof plus accrued interest at the Mortgage Interest Rate.
 
        (h)  all  amounts  representing  certain  expenses  reimbursable  to the
    Servicer and other amounts  permitted to be withdrawn  by the Servicer  from
    the Certificate Account, in each case pursuant to the applicable Pooling and
    Servicing Agreement;
 
        (i)  all amounts in the nature of late fees, assumption fees, prepayment
    fees  and similar fees which the Servicer  is entitled to retain pursuant to
    the applicable Pooling and Servicing Agreement; and
 
        (j)   reinvestment  earnings on  payments  received in  respect  of  the
    Mortgage Loans.
 
    The Servicer will calculate the portion of the Distributable Amount for each
Class  of the Series that  is available to be paid  out of the Pool Distribution
Amount on such  date. The portion  so available  on a Distribution  Date to  the
Senior   Certificateholders   and   to   the   Subordinated   Certificateholders
(respectively, the "Senior Class Pro Rata Share" and the "Subordinated Class Pro
Rata Share")  will  be  the  amount  equal  to  the  product  of  (a)  the  Pool
Distribution  Amount for such date and (b)  a fraction the numerator of which is
the Distributable Amount  for such  Class on such  date and  the denominator  of
which is the sum of the Distributable Amounts for such Series on such date.
 
                                       26
<PAGE>
    On  each Distribution  Date for a  Series of  Percentage Certificates (other
than Shifting Interest Certificates), the holders of the Senior Certificates  of
such  Series will be entitled to receive the Senior Class Pro Rata Share of such
Class on such Distribution Date. In  addition, to the extent credit  enhancement
is  available on such  Distribution Date, the  Senior Certificateholders will be
entitled to receive the  amount by which the  Senior Class Distributable  Amount
plus   any  Senior  Class  Carryover  Shortfall   (as  defined  below)  on  such
Distribution Date exceeds the Senior Class  Pro Rata Share on such  Distribution
Date  (such excess  being referred to  herein as the  "Senior Class Shortfall").
Such credit  support  includes:  (a)  amounts  otherwise  distributable  to  the
Subordinated  Certificateholders on such Distribution Date and amounts available
for such  purpose in  the Subordination  Reserve Fund  as described  below;  (b)
amounts   held  in   the  Certificate   Account  for   future  distributions  to
Certificateholders;  and  (c)  amounts  available  under  any  form  of   credit
enhancement  (other  than subordination)  which is  specified in  the applicable
Prospectus Supplement.  See "Credit  Support"  below. The  manner in  which  any
available  credit support will  be allocated among Subclasses  of a Senior Class
will be set forth in the  applicable Prospectus Supplement. With respect to  any
Distribution  Date, the "Senior Class Carryover  Shortfall" means the excess, if
any, of (a) the amount the Senior Certificateholders were entitled to receive on
the prior  Distribution  Date  less the  amount  the  Senior  Certificateholders
received  on such prior Distribution Date, together with interest thereon at the
Pass-Through Rate of such Senior Class from such prior Distribution Date through
the current Distribution Date, over (b)  the portion of the amount specified  in
clause (a) constituting Late Payments, together with interest on such portion at
the  applicable Pass-Through Rate from such  prior Distribution Date through the
current Distribution Date, to the extent such Late Payments and interest thereon
are included  in  the Pool  Distribution  Amount  with respect  to  the  current
Distribution Date.
 
    With  respect to  a Series of  Percentage Certificates  (other than Shifting
Interest Certificates) including a Class of Subordinated Certificates, once  the
Subordinated  Amount is  reduced to zero,  any remaining  Senior Class Shortfall
with respect to a  Class of Senior  Certificates will cease  to be payable  from
amounts  otherwise distributable to the  Subordinated Certificateholders and the
amounts in  the related  Subordination Reserve  Fund, if  any, except  that  the
portion  of such Senior Class Shortfall which  is attributable to the accrual of
interest on the Senior  Class Carryover Shortfall  (the "Senior Class  Shortfall
Accruals")  shall continue to bear interest at the applicable Pass-Through Rate,
and the Senior Certificateholders shall continue to have a preferential right to
be paid such amounts from distributions otherwise available to the  Subordinated
Certificateholders   until  such  amount  (including  interest  thereon  at  the
applicable   Pass-Through    Rate)    is    paid   in    full.    See    "Credit
Support--Subordination" below.
 
    The  Subordinated  Certificateholders will  be  entitled to  receive  on any
Distribution Date an amount equal to the Subordinated Class Pro Rata Share less:
(a) any  amounts required  to be  distributed to  the Senior  Certificateholders
pursuant   to   the   subordination   of   the   rights   of   the  Subordinated
Certificateholders as described below; and (b) any amounts necessary to fund the
Subordination Reserve Fund as described below. See "Credit
Support--Subordination" below.
 
  SHIFTING INTEREST CERTIFICATES
 
    On each Distribution Date  for a series  of Shifting Interest  Certificates,
the  Servicer will distribute on behalf of the Trustee or cause the Paying Agent
to distribute, as the case may be, to  the holders of record on the Record  Date
of a Class of Senior Certificates, to the extent of the Pool Distribution Amount
with  respect to such  Distribution Date (as  determined by the  Servicer on the
related Determination Date in the same manner as described above with respect to
Percentage Certificates other than Shifting Interest Certificates) and prior  to
any  distribution being made on the related Subordinated Certificates, an amount
equal to the  Senior Class  Distribution Amount. The  Senior Class  Distribution
Amount  will  (except  as  otherwise  set  forth  in  the  applicable Prospectus
Supplement) be calculated  for any Distribution  Date as the  lesser of (x)  the
Pool Distribution Amount for such Distribution Date and (y) the sum of:
 
         (i)  one month's interest  at the applicable  Pass-Through Rate on such
    Class's outstanding principal balance (less, if specified in the  applicable
    Prospectus  Supplement,  (a) the  amount by  which the  aggregate Prepayment
    Interest Shortfall with respect to the preceding month exceeds the aggregate
    Servicing Fees, in each case allocated to such Class on the basis set  forth
    in the related Prospectus Supplement, (b) the aggregate Curtailment Interest
    Shortfall with respect to the preceding
 
                                       27
<PAGE>
    month  allocated  to  such Class  and/or  (c)  one month's  interest  at the
    applicable Net Mortgage Interest Rate on such Class's percentage,  specified
    in  the applicable Prospectus Supplement, of the Scheduled Principal Balance
    of each Special Hazard  Mortgage Loan (as defined  below) covered by  clause
    (iv) below);
 
        (ii)  if distribution of  the amount of  interest calculated pursuant to
    clause (i) above on any prior Distribution Date was not made in full on such
    prior Distribution Date, an amount equal  to (a) the difference between  (x)
    the  amount of interest which the holders  of such Class would have received
    on the prior Distribution Date if there had been sufficient funds  available
    in  the  Certificate  Account  and  (y)  the  amount  of  interest  actually
    distributed to such holders on  such prior Distribution Date, together  with
    interest  on such difference (to the  extent permitted by applicable law) at
    the applicable  Pass-Through  Rate  of  such  Class  (the  "Unpaid  Interest
    Shortfall")  less (b) the aggregate amount distributed on Distribution Dates
    subsequent to  such  prior Distribution  Date  with respect  to  the  Unpaid
    Interest Shortfall;
 
        (iii)  such Class's percentage, calculated as provided in the applicable
    Prospectus Supplement, of  (a) all  scheduled payments of  principal due  on
    each  outstanding Mortgage Loan, on  the Due Date occurring  in the month in
    which the Distribution  Date occurs, (b)  all partial principal  prepayments
    applied by the Servicer in reduction of the unpaid principal of any Mortgage
    Loan  on or after the Determination Date in the month preceding the month in
    which the Distribution Date occurs (or  after the Cut-Off Date, in the  case
    of  the  first  Distribution  Date)  and  prior  to  the  Determination Date
    occurring in the month in which the Distribution Date occurs, and (c) except
    for Special  Hazard  Mortgage  Loans  covered  by  clause  (iv)  below,  the
    Scheduled  Principal  Balance  of  each  Mortgage  Loan  which,  during such
    preceding month, (i) was the subject of a principal prepayment in full, (ii)
    became a liquidated Mortgage Loan, or (iii) was repurchased by the Seller or
    purchased by the person  or persons specified  in the applicable  Prospectus
    Supplement pursuant to the Pooling and Servicing Agreement; and
 
        (iv)  such Class's specified percentage  of the net Liquidation Proceeds
    from any Mortgage  Loan that became  a Special Hazard  Mortgage Loan  during
    such  preceding month (but  only if the Special  Hazard Termination Date (as
    defined below) has occurred);
 
provided that, if such Distribution Date  falls on or after the Cross-Over  Date
(i.e.,  the date on which the amount of principal payments on the Mortgage Loans
to which the holders of the  related Subordinated Certificates are entitled  has
been reduced to zero as a result of the allocation of losses to the Subordinated
Certificates),  then the Senior Class Distribution Amount will instead equal the
lesser of (x) the Pool Distribution Amount and (y) the sum of the items referred
to above plus the amount by which such Class's outstanding principal balance  as
of  such Distribution  Date exceeds the  Pool Scheduled Principal  Balance as of
such  Distribution  Date.  The  Pool  Scheduled  Principal  Balance  as  of  any
Distribution  Date is the  aggregate of the Scheduled  Principal Balances of all
Mortgage Loans in a Trust Estate that  were outstanding on the first day of  the
month prior to the month in which such Distribution Date falls.
 
    If  so provided in the applicable Prospectus Supplement, one or more Classes
of Senior  Certificates  will also  be  entitled to  receive,  as its  or  their
specified  percentage(s) referred  to in clauses  (y)(iii)(b) and (y)(iii)(c)(i)
above, all partial principal prepayments  and all principal prepayments in  full
on the Mortgage Loans in the related Trust Estate under the circumstances or for
the period of time specified therein, which will have the effect of accelerating
the  amortization  of the  Senior Certificates  while increasing  the respective
interest evidenced by the Subordinated Certificates in the related Trust Estate.
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.
 
    If the Special Hazard Termination Date would occur on any Distribution  Date
under  the circumstances  referred to in  "Credit Support--Subordination" below,
the Senior Class Distribution  Amount for each Class  of Senior Certificates  of
such  Series calculated  as set  forth in the  two preceding  paragraphs will be
modified to the extent described in such section.
 
                                       28
<PAGE>
    Amounts distributed to a Class of Senior Certificates on a Distribution Date
will be deemed to be applied first  to the payment of current interest, if  any,
due  on such Class (i.e., the amount calculated pursuant to clause (y)(i) of the
third preceding  paragraph),  second  to  the payment  of  any  Unpaid  Interest
Shortfall  (i.e.,  the  amount calculated  pursuant  to clause  (y)(ii)  of such
paragraph) and third  to the payment  of principal,  if any, due  on such  Class
(i.e.,  the aggregate of the amounts calculated pursuant to clauses (y)(iii) and
(y)(iv) of such paragraph).
 
    As indicated above, in  the event that the  Pool Distribution Amount on  any
Distribution  Date is  not sufficient to  make the full  distribution of current
interest to the holders of a  Class of Senior Certificates entitled to  payments
of  interest, the  difference between the  amount of current  interest which the
holders of such Class would have received on such Distribution Date if there had
been sufficient  funds available  and the  amount actually  distributed will  be
added  to the amount of interest which the holders of such Class are entitled to
receive on  the  next  Distribution  Date. Unless  otherwise  specified  in  the
applicable  Prospectus Supplement, the amount of  any such interest shortfall so
carried forward will bear interest (to  the extent permitted by applicable  law)
at the Pass-Through Rate applicable to such Class.
 
    If  the Pool Distribution Amount is insufficient on any Distribution Date to
make the full distribution of principal  due on a Class of Senior  Certificates,
the  percentage  of  principal  payments  to which  the  holders  of  the Senior
Certificates would be entitled on  the immediately succeeding Distribution  Date
will be increased. This increase will have the effect of reducing, as a relative
matter,  the respective interest of the holders of the Subordinated Certificates
in future  payments of  principal on  the related  Mortgage Loans.  If the  Pool
Distribution  Amount is not sufficient to make full distribution described above
to the holders of  all Classes of Senior  Certificates on any Distribution  Date
(assuming  that more  than one  Class or  Subclass of  Senior Certificates  of a
Series has been issued), unless otherwise specified in the applicable Prospectus
Supplement, the holders of each such Class  or Subclass will share in the  funds
actually  available in proportion to the respective amounts that each such Class
or Subclass would have received had the Pool Distribution Amount been sufficient
to make the full distribution of interest  and principal due to each such  Class
or Subclass.
 
    Unless  otherwise  provided in  the related  Prospectus Supplement,  on each
Distribution Date the holders of  the related Subordinated Certificates will  be
entitled  to receive (in the amounts specified therein if there is more than one
Class of Subordinated Certificates), out of funds available for distribution  in
the  related  Certificate  Account on  such  date, all  amounts  remaining after
deduction of  the amounts  required to  be  distributed to  the holders  of  all
Classes of Senior Certificates of the same Series.

EXAMPLE OF DISTRIBUTION TO PERCENTAGE CERTIFICATEHOLDERS
 
    The  following  chart  sets  forth  an example  of  the  application  of the
foregoing provisions  to the  first two  months of  the related  Trust  Estate's
existence,  assuming the Certificates are issued in the month of January, with a
Distribution Date on the 25th of each month and a Determination Date on the 17th
of each month:
 
<TABLE>
<S>                         <C>
January 1(A)..............  Cut-Off Date.
January 2-January 31(B)...  The Servicer receives  any principal prepayments  in
                            full  (including prepayments due to liquidation) and
                            interest thereon to date of prepayment.
January 31(C).............  Record Date.
February 1-February         The  Servicer   receives   scheduled   payments   of
  17(D)...................  principal and interest due on February 1.
February 17(E)............  Determination Date.
February 25(F)............  Distribution Date.
</TABLE>
 
- ------------------------
(A) The initial unpaid principal balance of the Mortgage Loans in a Trust Estate
    would be the aggregate unpaid principal balance of the Mortgage Loans at the
    close of business on January 1, after deducting principal payments due on or
    before  such date. Those principal  payments due on or  before January 1 and
    the related interest  payments, would not  be part of  the Trust Estate  and
    would be remitted by the Servicer to the Seller when received.
 
(B)  Principal prepayments in full received during this period would be credited
    to the Certificate  Account for  distribution to  Certificateholders on  the
    February  25 Distribution Date. When  a Mortgage Loan is  prepaid in full or
    liquidated or an insurance claim with respect to a Mortgage Loan is settled,
    interest on  the amount  prepaid, liquidated  or received  in settlement  is
    collected  only from the last scheduled Due  Date to the date of prepayment,
    liquidation or settlement. In addition, when  a Mortgage Loan is prepaid  in
    part  and  such payment  is applied  as of  a  date other  than a  Due Date,
    interest is charged on such payment only to the date applied. To the  extent
    funds  are available from the aggregate Servicing Fees relating to mortgagor
    payments or  other  recoveries  distributed  to  Certificateholders  on  the
    related  Distribution Date, the Servicer would make an additional payment to
    Certificateholders with respect to any Mortgage Loan that prepaid in full or
    became a liquidated Mortgage Loan in January equal to the amount of interest
    on such Mortgage Loan  at the Net Mortgage  Interest Rate for such  Mortgage
    Loan from the date of such prepayment in full or liquidation through January
    31.
 
(C) Distributions in the month of February will be made to Certificateholders of
    record at the close of business on this date.
 
(D)  Scheduled monthly  payments on  the Mortgage Loans  due on  February 1, and
    partial principal prepayments applied  by the Servicer  in reduction of  the
    unpaid  principal balance of any Mortgage Loan prior to February 17, will be
    deposited in the Certificate Account as received by the Servicer and will be
    distributed to  Certificateholders on  the  February 25  Distribution  Date.
    Principal  prepayments  in  full,  liquidation  proceeds  and  proceeds with
    respect to the repurchase or purchase of any of the Mortgage Loans, in  each
    case  received during this period, and partial principal prepayments applied
    on or after February  17, will be deposited  in the Certificate Account  but
    will   not  be  distributed   to  Certificateholders  on   the  February  25
    Distribution Date. Instead, such amounts will be credited to the Certificate
    Account for distribution to Certificateholders on the March 25  Distribution
    Date.
 
(E)  As of the close of business on February 17, the Servicer will determine the
    amounts of Periodic Advances and the amounts of principal and interest which
    will be distributed to the Certificateholders, including scheduled  payments
    due  on or before February 1 which  have been received on or before February
    17, partial principal prepayments  applied by the  Servicer in reduction  of
    the  unpaid principal balance of any Mortgage  Loan prior to February 17 and
    principal prepayments  in  full,  liquidation proceeds,  and  proceeds  with
    respect to the repurchase or purchase of any of the Mortgage Loans, received
    during  the  period commencing  January  2 and  ending  on January  31. With
    respect to  each  Series of  Percentage  Certificates, other  than  Shifting
    Interest  Certificates, the Servicer will calculate the Distributable Amount
    and  the  Pro  Rata  Share  for   each  Class,  and  the  amount   otherwise
    distributable  to the Subordinated Class, together  with amounts, if any, in
    the Subordination Reserve  Fund, will  be available,  to the  extent of  the
    Subordinated   Amount,  to   increase  the   amount  distributable   to  the
 
                                         (FOOTNOTES CONTINUED ON FOLLOWING PAGE)

    Succeeding monthly periods  follow the  pattern of (B)  through (F),  except
that the period in (B) begins on the first of the month.
 
DISTRIBUTIONS TO MULTI-CLASS CERTIFICATEHOLDERS
 
    The following description of distributions to Multi-Class Certificateholders
is  one  example of  how such  distributions may  be determined.  The Prospectus
Supplement  for  a  Series  may  provide   for  a  different  manner  in   which
distributions  to  Multi-Class Certificateholders  will  be determined  for such
Series so long as such Multi-Class  Certificates are rated upon issuance in  one
of the two highest rating categories by at least one Rating Agency.
 
    Except  as  otherwise set  forth  in the  applicable  Prospectus Supplement,
distributions of interest and distributions in reduction of the Stated Amount of
Multi-Class Certificates  will be  made from  the Pool  Distribution Amount  (as
determined  by the Servicer on the related Determination Date in the same manner
as described above with  respect to Series of  Percentage Certificates) on  each
Distribution  Date for such Series to the holders of each Class then entitled to
receive such distributions until the aggregate amount of such distributions have
reduced  the  Stated  Amount  of  each  such  Class  of  Certificates  to  zero.
Distributions  in reduction of Stated Amount will be allocated among the Classes
of such  Certificates  in the  manner  specified in  the  applicable  Prospectus
Supplement.  Unless otherwise specified in the applicable Prospectus Supplement,
all distributions in reduction  of the Stated Amount  of a Class of  Multi-Class
Certificates will be made pro rata among the Certificates of such Class.
 
    Unless otherwise specified in the Prospectus Supplement relating to a Series
of  Certificates, the aggregate amount that  will be distributed in reduction of
Stated Amount to holders of Multi-Class  Certificates of a Series then  entitled
thereto on any Distribution Date for such Series will equal, to the extent funds
are  available, the sum  of (i) the  Multi-Class Certificate Distribution Amount
(as defined herein)  and (ii)  if and  to the  extent specified  in the  related
Prospectus Supplement, the applicable percentage of the Spread specified in such
Prospectus Supplement.
 
    Unless  otherwise  specified in  the  applicable Prospectus  Supplement, the
"Multi-Class Certificate  Distribution Amount"  with respect  to a  Distribution
Date  for a Series of Multi-Class Certificates will equal the amount, if any, by
which the Stated Amount  of the Multi-Class Certificates  of such Series  (after
taking  into account the amount of interest to  be added to the Stated Amount of
any Class of Compound Interest Certificates on such Distribution Date and before
giving effect  to  any distributions  in  reduction  of Stated  Amount  on  such
Distribution  Date) exceeds the  Pool Value (as defined  herein) of the Mortgage
Loans included in the Trust Estate for such  Series as of the end of the  period
(a "Due Period") specified in the related Prospectus Supplement. For purposes of
determining  the Multi-Class Certificate  Distribution Amount with  respect to a
Distribution Date for  a Series of  Certificates having one  or more Classes  of
Multi-Class  Certificates, the Pool Value of  the Mortgage Loans included in the
Trust Estate for  such Certificates  will be reduced  to take  into account  all
distributions thereon received by the Trustee during the applicable Due Period.
 
    Unless otherwise specified in the applicable Prospectus Supplement, "Spread"
with  respect to  a Distribution Date  for a Series  of Multi-Class Certificates
will be the excess of (a) the sum of (i) all payments of principal and  interest
received on the related Mortgage Loans (net of the Fixed Retained Yield, if any,
and the
 
- --------------------------------------------------------------------------------
(FOOTNOTES CONTINUED FROM PRECEDING PAGE)
    Senior  Class or Classes up to the Senior Class Shortfall in respect of such
    Classes. With respect to each Series of Shifting Interest Certificates,  the
    Servicer will calculate the Senior Class Distribution Amount for each Senior
    Class and will determine the percentage interests of each Senior Class to be
    used  in connection with calculating  Senior Class Distribution Amounts with
    respect to the March 25 Distribution Date. If applicable, the Servicer  will
    calculate  the  amounts  payable in  respect  of  any other  form  of credit
    enhancement.
 
(F) Unless  otherwise so  specified in  the related  Prospectus Supplement,  the
    Servicer  or the Paying Agent  will make distributions to Certificateholders
    on the 25th day of each month, or if such 25th day is not a business day, on
    the next business day.

applicable Servicing Fee with respect to such Mortgage Loans) in the Due  Period
applicable  to such Distribution Date and, in  the case of the first Due Period,
any amount deposited  by the Seller  in the Certificate  Account on the  Closing
Date,  (ii) income from  reinvestment thereof, if  any, and (iii)  to the extent
specified in the applicable Prospectus Supplement, the amount of cash  withdrawn
from  any reserve fund or  available under any other  form of credit enhancement
for such  Series, over  (b)  the sum  of (i)  all  interest distributed  on  the
Multi-Class  Certificates of  such Series  on such  Distribution Date,  (ii) the
Multi-Class Certificate Distribution Amount for such Series with respect to such
Distribution Date, (iii) if applicable to such Series, any Special Distributions
(as described  below) in  reduction  of the  Stated  Amount of  the  Multi-Class
Certificates  of such Series made since the preceding Distribution Date for such
Series (or since the Closing Date in the case of the first Distribution Date for
such Series),  including  any accrued  interest  distributed with  such  Special
Distributions,  (iv) all administrative and other expenses relating to the Trust
Estate payable during  the Due  Period preceding such  Distribution Date,  other
than such expenses which are payable by the Servicer, and any amount required to
be  deposited  into any  reserve fund  from funds  allocable to  the Multi-Class
Certificates in the Certificate Account. Reinvestment income on any reserve fund
will not be included in Spread except to the extent that reinvestment income  is
taken into account in calculating the initial amount required to be deposited in
such reserve fund, if any.
 
  VALUATION OF MORTGAGE LOANS
 
    If   specified  in  the  Prospectus  Supplement  relating  to  a  series  of
Multi-Class Certificates, for purposes of  establishing the principal amount  of
Mortgage  Loans that will  be included in  a Trust Estate  for such Series, each
Mortgage Loan to be included  in such Trust Estate  will be assigned an  initial
"Pool   Value."  Unless   otherwise  specified  in   the  applicable  Prospectus
Supplement, the Pool  Value of  each Mortgage  Loan in  the Trust  Estate for  a
Series  is the Stated  Amount of Multi-Class Certificates  of such Series which,
based upon  certain  assumptions  and  regardless of  any  prepayments  on  such
Mortgage  Loans, can  be supported  by the  scheduled payments  of principal and
interest on  such  Mortgage Loans  (net  of the  Fixed  Retained Yield  on  such
Mortgage  Loans,  if  any,  and the  applicable  Servicing  Fee),  together with
reinvestment earnings thereon, if any, at the Assumed Reinvestment Rate for  the
period  specified in the related Prospectus  Supplement and amounts available to
be withdrawn  (if applicable)  from any  reserve fund  for such  Series, all  as
specified in the applicable Prospectus Supplement. In calculating the Pool Value
of  a Mortgage Loan included  in the Trust Estate,  future distributions on such
Mortgage Loan will be  determined based on scheduled  payments on such  Mortgage
Loan.  Any similar  Mortgage Loans  may be  aggregated into  one or  more groups
(each, a "Pool Value Group"), each of  which will be assigned an aggregate  Pool
Value  calculated  as  if  all  such Mortgage  Loans  in  the  Pool  Value Group
constituted a single  mortgage loan  having the  highest mortgage  rate and  the
longest  maturity of any such mortgage loan for such Pool Value Group. There are
a number of alternative means of determining  the Pool Value of a Mortgage  Loan
or  Pool Value Group,  including determinations based  on the discounted present
value of the remaining scheduled payments of principal and interest thereon  and
determinations  based on  the relationship  between the  Mortgage Interest Rates
borne thereby and  the Interest  Rates of  the Multi-Class  Certificates of  the
related  Series. The  Prospectus Supplement  for each  Series will  describe the
method or methods (and related assumptions) used to determine the Pool Values of
the Mortgage Loans or the  Pool Value Groups for such  Series. In any event,  on
each  Distribution Date, after  making the distributions  in reduction of Stated
Amount on  such Distribution  Date, the  aggregate  of the  Pool Values  of  all
Mortgage  Loans and all the Pool Value Groups included in the Trust Estate for a
Series of Certificates will be at least equal to the aggregate Stated Amount  of
the Multi-Class Certificates of such Series.
 
    The  "Assumed Reinvestment  Rate" for  a Series  of Multi-Class Certificates
will be  the highest  rate permitted  by the  Rating Agency  or Rating  Agencies
rating  such Series of Multi-Class Certificates or  a rate insured by means of a
surety bond, guaranteed investment contract or similar arrangement  satisfactory
to such Rating Agency or Rating Agencies. If the Assumed Reinvestment Rate is so
insured,  the related  Prospectus Supplement  will set  forth the  terms of such
arrangement.

  SPECIAL DISTRIBUTIONS
 
    To the extent specified in the Prospectus Supplement relating to a Series of
Multi-Class Certificates which have other  than monthly Distribution Dates,  any
such  Classes  having  Stated  Amounts  may  receive  special  distributions  in
reduction of Stated Amount, together with accrued interest on the amount of such
reduction ("Special Distributions") in any month, other than a month in which  a
Distribution  Date  occurs, if,  as  a result  of  principal prepayments  on the
Mortgage Loans  in the  related  Trust Estate  and/or reinvestment  yields  then
available,  the  Trustee  determines,  based  on  assumptions  specified  in the
applicable Pooling and Servicing Agreement, that the amount of cash  anticipated
to  be available on the next Distribution Date for such Series to be distributed
to the holders of such Multi-Class Certificates may be less than the sum of  (i)
the  interest scheduled to be distributed to such holders and (ii) the amount to
be distributed in reduction of Stated Amount of such Multi-Class Certificates on
such Distribution Date. Any such Special Distributions will be made in the  same
priority and manner as distributions in reduction of Stated Amount would be made
on the next Distribution Date.
 
    To  the extent specified  in the related Prospectus  Supplement, one or more
Classes of Certificates of a Series  of Multi-Class Certificates may be  subject
to special distributions in reduction of the Stated Amount thereof at the option
of  the  holders of  such  Certificates, or  to  mandatory distributions  by the
Servicer. Any such distributions with respect  to a Series will be described  in
the applicable Prospectus Supplement and will be on such terms and conditions as
described  therein and specified in the Pooling and Servicing Agreement for such
Series.
 
  LAST SCHEDULED DISTRIBUTION DATE
 
    The "Last  Scheduled  Distribution  Date"  for  each  Class  of  Multi-Class
Certificates  of a Series having  a Stated Amount, to  the extent Last Scheduled
Distribution Dates are specified in the applicable Prospectus Supplement, is the
latest date on  which (based upon  the assumptions set  forth in the  applicable
Prospectus Supplement) the Stated Amount of such Class is expected to be reduced
to  zero. Since the rate of distributions  in reduction of Stated Amount of each
such Class of Multi-Class Certificates will depend upon, among other things, the
rate of payment (including prepayments) of  the principal of the Mortgage  Loans
in  the Trust Estate for such Series,  the actual last Distribution Date for any
such  Class  could   occur  significantly  earlier   than  its  Last   Scheduled
Distribution  Date. To  the extent  of any  delays in  receipt of  any payments,
insurance proceeds or liquidation  proceeds with respect  to the Mortgage  Loans
included  in any  Trust Estate,  the last Distribution  Date for  any such Class
could occur  later  than its  Last  Scheduled  Distribution Date.  The  rate  of
payments  on  the  Mortgage  Loans  in  the  Trust  Estate  for  any  Series  of
Certificates will depend upon  their particular characteristics,  as well as  on
the  prevailing level  of interest  rates from time  to time  and other economic
factors, and no assurance can be given as to the actual prepayment experience of
the Mortgage Loans. See "Prepayment and Yield Considerations" below.

SUBORDINATION
 
  CERTIFICATES OTHER THAN SHIFTING INTEREST CERTIFICATES
 
    If so  specified  in the  Prospectus  Supplement  relating to  a  Series  of
Certificates,  other than a Series of Shifting Interest Certificates, the rights
of the holders of a Class of Subordinated Certificates to receive  distributions
will  be  subordinated  to  the rights  of  the  holders of  a  Class  of Senior
Certificates, to  the  extent  of  the Subordinated  Amount  specified  in  such
Prospectus  Supplement. The  Subordinated Amount  will be  reduced by  an amount
equal to  Aggregate Losses  and will  be further  reduced in  accordance with  a
schedule  described in the applicable Prospectus Supplement. Aggregate Losses as
defined in the applicable Pooling and  Servicing Agreement for any given  period
will  equal the aggregate amount of delinquencies, losses and other deficiencies
("Payment Deficiencies") in  the amounts  due to  the Senior  Certificateholders
paid or borne by the Subordinated Certificateholders (but excluding any payments
of  Senior Class  Shortfall Accruals  or interest  thereon) during  such period,
whether  such  aggregate  amount  results   by  way  of  withdrawals  from   the
Subordination  Reserve Fund (including, prior to  the time that the Subordinated
Amount
 
                                       33
<PAGE>
is reduced to zero, any such  withdrawal of amounts attributable to the  Initial
Deposit,  if  any),  reductions  in  amounts  that  would  otherwise  have  been
distributable to the Subordinated  Certificateholders on any Distribution  Date,
or  otherwise;  less  the  aggregate  amount  of  previous  Payment Deficiencies
recovered by  the related  Trust Estate  during such  period in  respect of  the
Mortgage  Loans giving  rise to  such previous  Payment Deficiencies, including,
without limitation, such  recoveries resulting  from the  receipt of  delinquent
principal  or  interest payments,  Liquidation  Proceeds and  insurance proceeds
(net, in  each case,  of any  applicable  Fixed Retained  Yield and  any  unpaid
Servicing  Fee to  which the Servicer  is entitled, foreclosure  costs and other
servicing costs, expenses and advances relating to such Mortgage Loans).
 
    The  protection   afforded  to   the   Senior  Certificateholders   by   the
subordination  feature described above will be effected both by the preferential
right, to the extent specified in the applicable Prospectus Supplement, of  such
Senior  Certificateholders  to  receive  current  distributions  on  the related
Mortgage Loans that would otherwise have been distributable to the  Subordinated
Certificateholders  and (unless otherwise specified in the applicable Prospectus
Supplement) by the establishment and maintenance of a Subordination Reserve Fund
for such  Series.  Unless  otherwise  specified  in  the  applicable  Prospectus
Supplement,  the Subordination  Reserve Fund  will not  be a  part of  the Trust
Estate. The Subordination Reserve Fund may  be funded initially with an  initial
deposit  by the  Seller (the "Initial  Deposit") in  an amount set  forth in the
applicable  Prospectus  Supplement.  Following  the  initial  issuance  of   the
Certificates of a Series and until the balance of the Subordination Reserve Fund
(without  taking into account the amount of the Initial Deposit) first equals or
exceeds the  Specified  Subordination Reserve  Fund  Balance set  forth  in  the
applicable   Prospectus  Supplement,  and  unless  otherwise  specified  in  the
applicable Prospectus Supplement,  the Servicer will  withhold all amounts  that
would  otherwise have been distributable  to the Subordinated Certificateholders
and deposit such amounts (less any  portions thereof required to be  distributed
to  Senior Certificateholders as  described below) in  the Subordination Reserve
Fund. The time necessary for the Subordination Reserve Fund of a Series to reach
the applicable  Specified Subordination  Reserve Fund  Balance for  such  Series
after  the initial issuance of  the Certificates, and the  period for which such
balance is  maintained, will  be affected  by the  delinquency, foreclosure  and
prepayment  experience of  the Mortgage  Loans in  the related  Trust Estate and
cannot be accurately  predicted. Unless  otherwise specified  in the  applicable
Prospectus  Supplement,  after  the  amount in  the  Subordination  Reserve Fund
(without taking into  account the amount  of the Initial  Deposit) for a  Series
first  equals  or exceeds  the applicable  Specified Subordination  Reserve Fund
Balance, the Servicer will withhold from the Subordinated Certificateholders and
will deposit in  the Subordination Reserve  Fund such portion  of the  principal
payments  on  the Mortgage  Loans  otherwise distributable  to  the Subordinated
Certificateholders as may  be necessary  to maintain  the Subordination  Reserve
Fund  (without taking  into account  the amount of  the Initial  Deposit) at the
Specified Subordination Reserve Fund Balance. The Prospectus Supplement for each
Series will set  forth the amount  of the Specified  Subordination Reserve  Fund
Balance  applicable  from time  to time  and the  extent, if  any, to  which the
Specified Subordination Reserve Fund Balance may be reduced.
 
    In no event  will the  Specified Subordination  Reserve Fund  Balance for  a
Series  ever be  required to  exceed the Subordinated  Amount. In  the event the
Subordination Reserve Fund is depleted before the Subordinated Amount is reduced
to zero,  the Senior  Certificateholders will  continue to  have a  preferential
right,  to  the extent  specified in  the  applicable Prospectus  Supplement, to
receive  current  distributions  of  amounts  that  would  otherwise  have  been
distributable  to the Subordinated Certificateholders to  the extent of the then
Subordinated Amount.
 
    After  the   Subordinated   Amount   is  reduced   to   zero,   the   Senior
Certificateholders   of  a  Series  will,  unless  otherwise  specified  in  the
applicable Prospectus  Supplement,  nonetheless  have a  preferential  right  to
receive  payment  of  Senior Class  Shortfall  Accruals and  interest  which has
accrued thereon from amounts that would otherwise have been distributable to the
Subordinated Certificateholders.  The Senior  Certificateholders will  otherwise
bear  their proportionate share  of any losses  realized on the  Trust Estate in
excess of the Subordinated Amount.
 
                                       34
<PAGE>
    Amounts held  from time  to time  in the  Subordination Reserve  Fund for  a
Series  will be held  for the benefit  of the Senior  Certificateholders of such
Series until withdrawn from the Subordination Reserve Fund as described below.
 
    If on  any Distribution  Date while  the Subordinated  Amount exceeds  zero,
there  is a Senior Class Shortfall,  the Senior Class Certificateholders will be
entitled to  receive from  current payments  on the  Mortgage Loans  that  would
otherwise  have been distributable to Subordinated Certificateholders the amount
of such Senior Class  Shortfall. If such current  payments are insufficient,  an
amount  equal  to  the  lesser of:  (i)  the  entire amount  on  deposit  in the
Subordination Reserve  Fund  available for  such  purpose; or  (ii)  the  amount
necessary  to  cover  the Senior  Class  Shortfall  will be  withdrawn  from the
Subordination Reserve Fund. Amounts representing investment earnings on  amounts
held in the Subordination Reserve Fund will not be available to make payments to
the  Senior Certificateholders.  If current payments  on the  Mortgage Loans and
amounts available in the Subordination Reserve Fund are insufficient to pay  the
entire  Senior Class Shortfall, then amounts held in the Certificate Account for
future  distributions  will   be  distributed   as  necessary   to  the   Senior
Certificateholders.
 
    Amounts  withdrawn  from the  Subordination Reserve  Fund  for a  Series and
deposited in  the Certificate  Account for  such Series  will be  charged  first
against amounts in the Subordination Reserve Fund other than the Initial Deposit
for such Series, and thereafter against such Initial Deposit.
 
    Any amounts in the Subordination Reserve Fund for a Series on a Distribution
Date  in excess of the Specified Subordination Reserve Fund Balance on such date
prior to the time the  Subordinated Amount for such  Series is reduced to  zero,
and any amounts remaining in the Subordination Reserve Fund for such Series upon
termination  of  the  trust  created by  the  applicable  Pooling  and Servicing
Agreement, will be paid, unless otherwise specified in the applicable Prospectus
Supplement, to the Subordinated Certificateholders of such Series in  accordance
with  their pro rata ownership thereof, or, in the case of a Series with respect
to which an election has  been made to treat the  Trust Estate (or a  segregated
pool of assets therein) as a REMIC, first to the Residual Certificateholders (to
the  extent of  any portion  of the Initial  Deposit, if  any, and undistributed
reinvestment earnings  attributable thereto),  and  second to  the  Subordinated
Certificateholders  of such  Series, in each  case in accordance  with their pro
rata  ownership  thereof.   Amounts  permitted  to   be  distributed  from   the
Subordination  Reserve Fund for a Series will no longer be subject to any claims
or rights of the Senior Certificateholders of such Series.
 
    Funds in the  Subordination Reserve Fund  for a Series  will be invested  as
provided  in the applicable Pooling and  Servicing Agreement in certain types of
eligible investments ("Eligible Investments"). If  an election has been made  to
treat  the Trust Estate (or a segregated pool  of assets therein) as a REMIC, no
more than 30% of  the income or  gain of the Subordination  Reserve Fund in  any
taxable  year may be derived  from the sale or  other disposition of investments
held for less than three months in the Subordination Reserve Fund. The  earnings
on   such  investments   will  be  withdrawn   and  paid   to  the  Subordinated
Certificateholders  of  such  Series   or  to  the   holders  of  the   Residual
Certificates,  in the event  that an election  has been made  to treat the Trust
Estate (or a segregated pool of assets therein) with respect to such Series as a
REMIC, in accordance with their  respective interests. Investment income  earned
on  amounts held  in the  Subordination Reserve Fund  will not  be available for
distribution to the Senior Certificateholders or otherwise subject to any claims
or rights of the Senior Certificateholders.
 
    Eligible Investments for monies deposited in the Subordination Reserve  Fund
will  be specified in the applicable Pooling and Servicing Agreement and, unless
otherwise provided in the applicable Prospectus Supplement, will mature no later
than the next Distribution Date.
 
    Holders of Subordinated  Certificates of a  Series will not  be required  to
refund  any amounts which have been  properly distributed to them, regardless of
whether there are  sufficient funds to  distribute to Senior  Certificateholders
the amounts to which they are later entitled.
 
                                       35
<PAGE>
    If   specified  in  the  Prospectus  Supplement  relating  to  a  Series  of
Certificates, the Subordination Reserve Fund may  be funded in any other  manner
acceptable  to the  Rating Agency  and consistent with  an election,  if any, to
treat the Trust Estate (or a segregated pool of assets therein) for such  Series
as a REMIC, as will be more fully described in such Prospectus Supplement.
 
  SHIFTING INTEREST CERTIFICATES
 
    If  specified in  the applicable  Prospectus Supplement,  the rights  of the
holders of  the  Subordinated Certificates  of  a Series  of  Shifting  Interest
Certificates  to receive distributions with respect to the Mortgage Loans in the
related Trust Estate will be subordinated to  such rights of the holders of  the
Senior  Certificates of the same Series to the extent described below, except as
otherwise set  forth  in  such  Prospectus  Supplement.  This  subordination  is
intended  to  enhance the  likelihood of  regular receipt  by holders  of Senior
Certificates of the full amount of  scheduled monthly payments of principal  and
interest due them and to provide limited protection to the holders of the Senior
Certificates against losses due to mortgagor defaults.
 
    The protection afforded to the holders of Senior Certificates of a Series of
Shifting Interest Certificates by the subordination feature described above will
be  effected by the preferential right of  such holders to receive, prior to any
distribution being made in respect  of the related Subordinated Certificates  on
each  Distribution Date, current distributions on  the related Mortgage Loans 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 below,  by the right of  such holders to receive  future
distributions  on the Mortgage  Loans that would otherwise  have been payable to
the holders of Subordinated Certificates.
 
    Losses realized on liquidated Mortgage Loans (other than certain  liquidated
Mortgage  Loans that are Special Hazard  Mortgage Loans as described below) will
be allocated to the holders of Subordinated Certificates through a reduction  of
the amount of principal payments on the Mortgage Loans to which such holders are
entitled.  Prior to the Cross-Over Date,  holders of Senior Certificates of each
Class entitled to  a percentage of  principal payments on  the related  Mortgage
Loans  will be  entitled to  receive, as part  of their  respective Senior Class
Distribution Amounts  payable  on each  Distribution  Date in  respect  of  each
Mortgage  Loan that  became a  liquidated Mortgage  Loan in  the preceding month
(subject to the additional limitation  described below applicable to  liquidated
Mortgage  Loans that are Special Hazard Mortgage Loans), their respective shares
of the  Scheduled  Principal Balance  of  each such  liquidated  Mortgage  Loan,
together  with interest  accrued at the  applicable Net  Mortgage Interest Rate,
irrespective of whether net Liquidation Proceeds realized thereon are sufficient
to cover such amount.  For a description of  the full Senior Class  Distribution
Amount   payable  to  holders  of  Senior   Certificates  of  each  Series,  see
"Description of the Certificates--Distributions to Percentage
Certificateholders--Shifting Interest Certificates."
 
    On each Distribution Date occurring on or after the Cross-Over Date, holders
of Senior  Certificates of  each Class  entitled to  a percentage  of  principal
payments  will  generally  receive, as  part  of their  respective  Senior Class
Distribution Amounts,  only  their  respective shares  of  the  net  Liquidation
Proceeds  actually  realized in  respect of  the applicable  liquidated Mortgage
Loans after  reimbursement  to  the  Servicer  of  any  previously  unreimbursed
Periodic  Advances  made  in  respect of  such  liquidated  Mortgage  Loans. See
"Description of the Certificates--Distributions to Percentage
Certificateholders--Shifting Interest Certificates."
 
    In the event that a  Mortgage Loan becomes a  liquidated Mortgage Loan as  a
result  of a hazard not insured against under a standard hazard insurance policy
of the type described herein (a "Special Hazard Mortgage Loan"), the holders  of
Senior Certificates of each Class entitled to a percentage of principal payments
on  the related Mortgage  Loans will be  entitled to receive  in respect of each
Mortgage Loan  which became  a Special  Hazard Mortgage  Loan in  the  preceding
month,  as part of their respective Senior Class Distribution Amounts payable on
each Distribution  Date prior  to  the Special  Hazard Termination  Date,  their
respective  shares of  the Scheduled  Principal Balance  of such  Mortgage Loan,
together with interest  accrued at  the applicable Net  Mortgage Interest  Rate,
rather  than  their  respective  shares  of  net  Liquidation  Proceeds actually
realized. The Special Hazard Termination Date for a Series of Certificates  will
be  the earlier  to occur  of (i)  the date  on which  cumulative net  losses in
respect of Special Hazard Mortgage Loans exceed the
 
                                       36
<PAGE>
Special Hazard Loss Amount specified in the applicable Prospectus Supplement  or
(ii) the Cross-Over Date. Since the amount of the Special Hazard Loss Amount for
a  Series of Certificates  is expected to  be less than  the amount of principal
payments on  the  Mortgage  Loans  to which  the  holders  of  the  Subordinated
Certificates of such Series are initially entitled (such amount being subject to
reduction,  as described  above, as  a result of  allocation of  losses on other
liquidated Mortgage Loans as well as Special Hazard Mortgage Loans), the holders
of Subordinated Certificates of such Series will bear the risk of losses in  the
case  of Special Hazard  Mortgage Loans to  a lesser extent  than they will bear
losses on other liquidated Mortgage  Loans. Once the Special Hazard  Termination
Date  has occurred,  holders of  Senior Certificates  of each  Class entitled to
payments of principal will be entitled  to receive, as part of their  respective
Senior   Class  Distribution  Amounts,  only  their  respective  shares  of  net
Liquidation Proceeds realized on Special  Hazard Mortgage Loans (less the  total
amount  of  delinquent  installments  in respect  of  each  such  Special Hazard
Mortgage Loan that were previously the  subject of distributions to the  holders
of  Senior  Certificates  paid out  of  amounts otherwise  distributable  to the
holders of  the  Subordinated  Certificates of  such  Series).  The  outstanding
principal  balance of each such Class will,  however, be reduced by such Class's
specified percentage of  the Scheduled  Principal Balance of  each such  Special
Hazard  Mortgage Loan.  See "Description  of the  Certificates--Distributions to
Percentage Certificateholders--Shifting Interest Certificates."
 
    If the cumulative net losses  on all Mortgage Loans  in a Trust Estate  that
have  become Special Hazard Mortgage  Loans in the months  prior to the month in
which a Distribution Date occurs would exceed the Special Hazard Loss Amount for
a Series of Certificates, that portion  of the Senior Class Distribution  Amount
as  of such  Distribution Date  for each  Class of  Senior Certificates  of such
Series entitled to a percentage of  principal payments on the Mortgage Loans  in
the  related Trust  Estate attributable to  Mortgage Loans  which became Special
Hazard Mortgage Loans in the month preceding the month of such Distribution Date
will be calculated not on the basis of the Scheduled Principal Balances of  such
Special  Hazard Mortgage Loans but rather will be computed as an amount equal to
the sum of (i) the excess of the Special Hazard Loss Amount over the  cumulative
net  losses on all Mortgage  Loans that became Special  Hazard Mortgage Loans in
the months prior to the month of  such Distribution Date and (ii) the excess  of
(a)  the product of the percentage of  principal payments to which such Class is
entitled multiplied by the  aggregate net Liquidation  Proceeds of the  Mortgage
Loans  which became  Special Hazard  Mortgage Loans  in the  month preceding the
month of  such  Distribution  Date  over (b)  the  total  amount  of  delinquent
installments  in  respect  of  such  Special  Hazard  Mortgage  Loans  that were
previously the  subject of  distributions  to such  Class  paid out  of  amounts
otherwise distributable to the holders of the related Subordinated Certificates.
 
    Although  the subordination feature  described above is  intended to enhance
the likelihood of  timely payment of  principal and interest  to the holders  of
Senior  Certificates,  shortfalls  could result  in  certain  circumstances. For
example, a shortfall in  the payment of principal  otherwise due the holders  of
Senior  Certificates could occur if  losses realized on the  Mortgage Loans in a
Trust Estate  were exceptionally  high  and were  concentrated in  a  particular
month.   See  "Description  of  the  Certificates--Distributions  to  Percentage
Certificateholders--Shifting Interest  Certificates" for  a description  of  the
consequences of any shortfall of principal or interest.
 
    The  holders of Subordinated Certificates will not be required to refund any
amounts previously properly distributed to them, regardless of whether there are
sufficient funds on a subsequent Distribution  Date to make a full  distribution
to holders of each Class of Senior Certificates of the same Series.
 
OTHER CREDIT ENHANCEMENT
 
    In  addition to subordination as discussed  above, credit enhancement may be
provided with respect to  any Series of Certificates  in any other manner  which
may  be described  in the applicable  Prospectus Supplement,  including, but not
limited to,  credit enhancement  through an  alternative form  of  subordination
and/or one or more of the methods described below.
 
  LIMITED GUARANTEE
 
    If  so specified in  the Prospectus Supplement  with respect to  a Series of
Certificates, credit  enhancement may  be  provided in  the  form of  a  limited
guarantee issued by a guarantor named therein.
 
                                       37
<PAGE>
  LETTER OF CREDIT
 
    Alternative  credit support with respect to  a Series of Certificates may be
provided by  the  issuance of  a  letter of  credit  by the  bank  or  financial
institution  specified in  the applicable  Prospectus Supplement.  The coverage,
amount and frequency of any reduction in coverage provided by a letter of credit
issued with  respect to  a  Series of  Certificates will  be  set forth  in  the
Prospectus Supplement relating to such Series.
 
  POOL INSURANCE POLICIES
 
    If  so  specified  in the  Prospectus  Supplement  relating to  a  Series of
Certificates, the Seller will  obtain a pool insurance  policy for the  Mortgage
Loans in the related Trust Estate. The pool insurance policy will cover any loss
(subject  to the  limitations described in  a related  Prospectus Supplement) by
reason of default to the  extent a related Mortgage Loan  is not covered by  any
primary  mortgage insurance policy.  The amount and principal  terms of any such
coverage will be set forth in the Prospectus Supplement.
 
  SPECIAL HAZARD INSURANCE POLICIES
 
    If so specified in the applicable Prospectus Supplement, for each Series  of
Certificates  as to which a  pool insurance policy is  provided, the Seller will
also obtain a special  hazard insurance policy for  the related Trust Estate  in
the amount set forth in such Prospectus Supplement. The special hazard insurance
policy  will, subject to the limitations  described in the applicable Prospectus
Supplement, protect against  loss by  reason of damage  to Mortgaged  Properties
caused  by certain hazards not insured against under the standard form of hazard
insurance policy for the respective states in which the Mortgaged Properties are
located. The amount and principal terms of  any such coverage will be set  forth
in the Prospectus Supplement.
 
  MORTGAGOR BANKRUPTCY BOND
 
    If  so specified in  the applicable Prospectus  Supplement, losses resulting
from a  bankruptcy proceeding  relating to  a mortgagor  affecting the  Mortgage
Loans in a Trust Estate with respect to a Series of Certificates will be covered
under  a mortgagor bankruptcy bond (or any other instrument that will not result
in a downgrading of  the rating of  the Certificates of a  Series by the  Rating
Agency or Rating Agencies that rated such Series). Any mortgagor bankruptcy bond
or  such other  instrument will  provide for coverage  in an  amount meeting the
criteria of the Rating Agency or Rating Agencies rating the Certificates of  the
related  Series,  which  amount will  be  set  forth in  the  related Prospectus
Supplement. The amount  and principal  terms of any  such coverage  will be  set
forth in the Prospectus Supplement.
 
                      PREPAYMENT AND YIELD CONSIDERATIONS
 
PASS-THROUGH RATES AND INTEREST RATES
 
    Any  Class of Certificates of a Series may have a fixed Pass-Through Rate or
Interest Rate, or  a Pass-Through Rate  or Interest Rate  which varies based  on
changes  in an index or based on changes with respect to the underlying Mortgage
Loans (such as, for  example, varying on  the basis of  changes in the  weighted
average Net Mortgage Interest Rate of the underlying Mortgage Loans).
 
    The  Prospectus Supplement  for each Series  will specify the  range and the
weighted average of the Mortgage Interest Rates and, if applicable, Net Mortgage
Interest Rates for the Mortgage Loans  underlying such Series as of the  Cut-Off
Date.  If the Trust  Estate includes adjustable-rate  Mortgage Loans or includes
Mortgage Loans with different Net Mortgage Interest Rates, the weighted  average
Net  Mortgage Interest Rate may  vary from time to time  as set forth below. See
"The Trust Estates." The  Prospectus Supplement for a  Series will also  specify
the  initial weighted average Pass-Through Rate  or Interest Rate for each Class
of Certificates of such Series and  will specify whether each such  Pass-Through
Rate or Interest Rate is fixed or is variable.
 
    The  Net Mortgage Interest  Rate for any adjustable  rate Mortgage Loan will
change with  any  changes in  the  index  specified in  the  related  Prospectus
Supplement  on which such Mortgage Interest  Rate adjustments are based, subject
to any applicable periodic or aggregate  caps or floors on the related  Mortgage
Interest  Rate. The weighted average Net  Mortgage Interest Rate with respect to
any Series may vary due to
 
                                       38
<PAGE>
changes in the Net Mortgage Interest Rates of adjustable rate Mortgage Loans, to
the timing of the  Mortgage Interest Rate readjustments  of such Mortgage  Loans
and  to different  rates of  payment of  principal of  fixed or  adjustable rate
Mortgage Loans bearing  different Mortgage Interest  Rates. See "Prepayment  and
Yield Considerations."
 
SCHEDULED DELAYS IN DISTRIBUTIONS
 
    At  the date of initial issuance of  the Certificates of each Series offered
hereby, the initial purchasers  of a Class of  Certificates (other than  certain
Classes  of Residual Certificates)  will be required to  pay accrued interest at
the applicable  Pass-Through Rate  or  Interest Rate  for  such Class  from  the
Cut-Off  Date for such Series to, but  not including, the date of issuance. With
respect to Standard Certificates or  Stripped Certificates, the effective  yield
to  Certificateholders  will  be  below  the  yield  otherwise  produced  by the
applicable Pass-Through Rate because the distribution of principal and  interest
which  is due on each Due  Date will not be made until  the 25th day (or if such
25th day is not a business day, the business day immediately following such 25th
day) of  the  month  in  which  such  Due  Date  occurs  (or  until  such  other
Distribution  Date specified  in the  applicable Prospectus  Supplement). To the
extent set forth in the related Prospectus Supplement, Multi-Class  Certificates
may provide for distributions of interest accrued during periods ending prior to
the  related Distribution Date. In any such  event, the nature of such scheduled
delays in  distribution  and  the  impact  on  the  yield  of  such  Multi-Class
Certificates will be set forth in the related Prospectus Supplement.
 
EFFECT OF PRINCIPAL PREPAYMENTS
 
    When  a Mortgage Loan is prepaid in full, the mortgagor pays interest on the
amount prepaid only to  the date of prepayment  and not thereafter.  Liquidation
Proceeds  (as defined  herein) and amounts  received in  settlement of insurance
claims are  also likely  to include  interest only  to the  time of  payment  or
settlement.  When a  Mortgage Loan  is prepaid in  part, and  such prepayment is
applied as of a date other than the  Due Date occurring in the month of  receipt
or  the Due Date occurring in the month following the month of receipt, interest
is paid on the amount prepaid only to the date of prepayment and not thereafter.
The effect of the foregoing is to reduce the aggregate amount of interest  which
would  otherwise be passed  through to Certificateholders  if such Mortgage Loan
were outstanding or such partial prepayment  were applied on the succeeding  Due
Date.  To partially mitigate this reduction  in yield, the Pooling and Servicing
Agreement relating to a Series will  provide, unless otherwise specified in  the
applicable  Prospectus Supplement, that with respect to any principal prepayment
in full or liquidation of any Mortgage Loan underlying the Certificates of  such
Series,  the Servicer will pay  into the Certificate Account  for such Series to
the extent funds  are available for  such purpose from  the aggregate  Servicing
Fees  (or portion  thereof as  specified in  the related  Prospectus Supplement)
which the Servicer  is entitled  to receive  relating to  mortgagor payments  or
other  recoveries distributed to Certificateholders  on the related Distribution
Date, the amount, if any, of interest at the Net Mortgage Interest Rate for such
Mortgage Loan  for the  period  from the  date of  such  prepayment in  full  or
liquidation  to and including the  end of the month  in which such prepayment in
full or  liquidation  occurs.  Unless  otherwise  specified  in  the  applicable
Prospectus Supplement, no comparable yield support will be provided with respect
to  partial prepayments, and any interest  shortfall arising from application by
the Servicer of  partial prepayments  other than  on a  Due Date  will be  borne
solely  by the Certificateholders  of the related Series.  See "Servicing of the
Mortgage Loans--Adjustment  to  Servicing Fee  in  Connection with  Prepaid  and
Liquidated Mortgage Loans."
 
    A  lower  rate of  principal prepayments  than anticipated  would negatively
affect the total return to  investors in any Certificates  of a Series that  are
offered  at a discount to their principal  amount and a higher rate of principal
prepayments than  anticipated  would  negatively  affect  the  total  return  to
investors in the Certificates of a Series that are offered at a premium to their
principal  amount.  The  yield  on  Stripped  Certificates  may  be particularly
sensitive to prepayment rates, and further information with respect to yield  on
such  Stripped  Certificates  will  be  included  in  the  applicable Prospectus
Supplement.
 
                                       39
<PAGE>
WEIGHTED AVERAGE LIFE OF CERTIFICATES
 
    The Mortgage Loans may  be prepaid in  full or in part  at any time.  Unless
otherwise  specified in the  applicable Prospectus Supplement,  no Mortgage Loan
will provide  for  a  prepayment  penalty. Unless  otherwise  specified  in  the
applicable  Prospectus Supplement,  all fixed  rate Mortgage  Loans will contain
due-on-sale clauses permitting the mortgagee to accelerate the maturities of the
Mortgage Loans  upon conveyance  of the  related Mortgaged  Properties, and  all
adjustable-rate  Mortgage Loans will permit creditworthy borrowers to assume the
then-outstanding indebtedness on the Mortgage Loans.
 
    Prepayments on Mortgage Loans are commonly measured relative to a prepayment
standard or  model.  The  Prospectus  Supplement for  each  Series  of  Stripped
Certificates  may, and the Prospectus Supplement  for each Series of Multi-Class
Certificates will, describe one or more such prepayment standards or models  and
contain  tables setting forth the projected yields  to maturity on each Class or
Subclass of Certificates of a Series  of Stripped Certificates or, with  respect
to a Series of Multi-Class Certificates, the weighted average life of each Class
and  the percentage of the  original aggregate Stated Amount  of each Class that
would be outstanding on  specified Distribution Dates for  such Series based  on
the assumptions stated in such Prospectus Supplement, including assumptions that
prepayments  on the  Mortgage Loans are  made at rates  corresponding to various
percentages of  the  prepayment  standard  or model  specified  in  the  related
Prospectus Supplement.
 
    There  is no  assurance that prepayment  of the Mortgage  Loans underlying a
Series of Certificates will conform to  any level of the prepayment standard  or
model  specified  in the  related Prospectus  Supplement.  A number  of factors,
including  homeowner  mobility,  economic  conditions,  changes  in  mortgagors'
housing  needs, job transfers, unemployment or, in the case of borrowers relying
on commission income  and self-employed borrowers,  significant fluctuations  in
income  or adverse economic conditions, mortgagors' net equity in the properties
securing the  mortgages,  servicing  decisions,  enforceability  of  due-on-sale
clauses,  mortgage  market interest  rates,  mortgage recording  taxes,  and the
availability of mortgage  funds, may affect  prepayment experience. In  general,
however,  if  prevailing interest  rates fall  significantly below  the Mortgage
Interest Rates on the  Mortgage Loans underlying a  Series of Certificates,  the
prepayment  rates  of  such Mortgage  Loans  are  likely to  be  higher  than if
prevailing rates remain at or above the  rates borne by such Mortgage Loans.  It
should  be noted  that Certificates of  a Series  may evidence an  interest in a
Trust Estate with different Mortgage Interest Rates. Accordingly, the prepayment
experience of such Certificates will to some extent be a function of the mix  of
interest  rates of the Mortgage Loans. In addition, the terms of the Pooling and
Servicing Agreement will require the Servicer to enforce any due-on-sale  clause
to  the extent it has knowledge of  the conveyance or the proposed conveyance of
the underlying  Mortgaged  Property;  provided, however,  that  any  enforcement
action  that the Servicer in  good faith determines may  be restricted by law or
that would impair or threaten to impair any recovery under any related insurance
policy will not be required and provided, further, that the Servicer may  permit
the  assumption  of defaulted  Mortgage Loans.  See  "Servicing of  the Mortgage
Loans--Enforcement of Due-on-Sale Clauses;  Realization Upon Defaulted  Mortgage
Loans"  and "Certain Legal Aspects of the Mortgage Loans--'Due-On-Sale' Clauses"
for a description of certain provisions of each Pooling and Servicing  Agreement
and  certain legal developments that may affect the prepayment experience on the
Mortgage Loans.
 
    At the request of the mortgagor, the Servicer may allow the refinancing of a
Mortgage  Loan  in  any  Trust  Estate  by  accepting  prepayments  thereon  and
permitting  a new  loan secured by  a Mortgage  on the same  property. Upon such
refinancing, the new loan will not be included in the Trust Estate. A  mortgagor
may be legally entitled to require the Servicer to allow such a refinancing. Any
such  refinancing  will have  the same  effect as  a prepayment  in full  of the
related Mortgage Loan.  In this regard  PHMC may, from  time to time,  implement
programs  designed  to encourage  refinancing  through PHMC,  including  but not
limited to general or  targeted solicitations, or  the offering of  pre-approved
applications,  reduced  origination fees  or closing  costs, or  other financial
incentives. The Servicer  may also encourage  refinancing of defaulted  Mortgage
Loans,  including  Mortgage Loans  that would  permit creditworthy  borrowers to
assume the outstanding indebtedness.

    The Seller will  be obligated,  under certain  circumstances, to  repurchase
certain  of  the Mortgage  Loans. In  addition, if  specified in  the applicable
Prospectus Supplement, the Pooling and Servicing Agreement will permit, but  not
require, the Seller, and the terms of certain insurance policies relating to the
Mortgage  Loans may  permit the applicable  insurer, to  purchase any delinquent
Mortgage Loan. The proceeds of any such purchase or repurchase will be deposited
in the related Certificate Account and such purchase or repurchase will have the
same effect as a prepayment in full of the related Mortgage Loan. See "The Trust
Estates--Mortgage Loans--Assignment  of  the  Mortgage  Loans  to  the  Trustee"
and"--Optional  Repurchases."  In addition,  if so  specified in  the applicable
Prospectus Supplement, the Servicer  will have the option  to purchase all,  but
not  less than all, of the Mortgage Loans  in any Trust Estate under the limited
conditions  specified  in  such  Prospectus   Supplement.  For  any  Series   of
Certificates for which an election has been made to treat the Trust Estate (or a
segregated  pool of assets therein) as a  REMIC, any such purchase or repurchase
may be effected only pursuant to  a "qualified liquidation," as defined in  Code
Section  860F(a)(4)(A). See  "The Pooling  and Servicing Agreement--Termination;
Purchase of Mortgage Loans."

Mortgage  Securities  Company,  a  limited  purpose  general  partnership formed
pursuant to the Partnership Law  of the State of New  York on December 30,  1987
("PHMSCo.").  The Seller was incorporated in the State of Delaware on August 21,
1985 under the name Dryden Guaranty Corporation, but did not actively engage  in
business  prior  to December  28, 1988.  On  July 18,  1988, the  Certificate of
Incorporation of the Seller was amended to, among other things, change the  name

                                      PHMC
 
GENERAL
 
    PHMC is the successor in interest to The Prudential Home Mortgage Company, a
joint  venture which  was formed  under the  laws of  the State  of New  York on
November 7, 1984 ("PHMCo."). Immediately prior to November 1987, the partners of
PHMCo., each  of which  owned a  50% interest  in the  joint venture,  were  The
Prudential  Mortgage  Capital Company,  Inc., a  New  Jersey corporation  and an
indirect, wholly owned
 
                                       41
<PAGE>
subsidiary of Prudential Insurance ("PMCC") and TR Venture Corporation ("TRVC"),
a Delaware corporation indirectly,  wholly owned by  Salomon Inc and  affiliated
with  Salomon  Brothers  Inc.  During November  1987,  PMCC  transferred  a 0.1%
interest in PHMCo. to  its affiliate, PIC  Realty Corporation, and,  immediately
thereafter,  the  interest  of TRVC  in  PHMCo.  was retired.  As  a consequence
thereof, PHMCo. became indirectly, wholly owned by Prudential Insurance,  which,
in turn, also indirectly, wholly owns the Seller.
 
    PHMC was incorporated in the State of New Jersey on September 18, 1978 under
the  name Newark Rehabilitation,  Inc., but did not  actively engage in business
prior to October 31, 1988. On March 3, 1988, Newark Rehabilitation, Inc. changed
its name to  The Prudential  Home Mortgage Company,  Inc., and,  on October  31,
1988,  PHMC acquired  all of the  assets and  assumed all of  the liabilities of
PHMCo. As used herein and in each Prospectus Supplement, references to PHMC that
relate to activities  occurring prior  to October 31,  1988 are  to PHMCo.  From
October  31,  1988  to  December  19, 1989,  PHMC  was  a  direct,  wholly owned
subsidiary of PMCC. On December  19, 1989, all of the  common stock of PHMC  was
transferred   to,  and  PHMC  became  a  direct,  wholly  owned  subsidiary  of,
Residential Services Corporation of America,  a direct, wholly owned  subsidiary
of Prudential Insurance.
 
    PHMC  is engaged principally in the  business of originating and purchasing,
for its own account and for the account of its affiliates, residential  mortgage
loans  secured by one- to four-family homes located throughout the United States
and made in order to purchase those homes or to refinance prior loans secured by
such homes. PHMC  also processes  loans for other  originators. See  "--Mortgage
Origination Processing" below. The executive offices of PHMC are located at 8000
Maryland  Avenue, Suite 1400, Clayton, Missouri  63105, and its telephone number
is (314) 726-3900.
 
    PHMC is  an affiliate  of  Lender's Service,  Inc., a  Delaware  corporation
("LSI"),  formerly known as Lender's Service Acquisition Corporation, which is a
wholly owned subsidiary of  Residential Services Corporation  of America and  an
indirect  wholly  owned subsidiary  of Prudential  Insurance,  and which  is the
successor in interest to Lender's Service, Inc., a Pennsylvania corporation. LSI
maintains  a  relationship  with  a  nationwide  network  of  appraisers;  these
appraisers  perform work for LSI on an independent-contractor basis. Appraisals,
review appraisals  and recertifications  obtained  in connection  with  mortgage
loans  originated  or  acquired  by  PHMC  may  be  obtained  through  LSI.  See
"--Mortgage Loan Underwriting"  below. LSI  may also  act as  a title  insurance
agent  for various title insurance companies, and  as a vendor of credit reports
for UCB  Services,  a  national  mortgage reporting  company,  with  respect  to
mortgage  loans,  including the  Mortgage Loans.  PHMC is  also an  affiliate of
Prudential Property and  Casualty Insurance  Company, a  wholly owned,  indirect
subsidiary   of  Prudential  Insurance,  which  offers  casualty  insurance  for
residential properties, which may include  the Mortgaged Properties. PHMC is  an
affiliate  of The Prudential Bank  and Trust Company, a  Georgia bank, for which
PHMC processes  applications  for  home  equity  loans  secured  by  residential
properties,  which  may  include  the  Mortgaged  Properties.  PHMC  is  also an
affiliate of The Prudential Real Estate Affiliates, Inc., which may, directly or
through real estate brokers,  refer loan originations to  PHMC. PHMC is also  an
affiliate  of The Prudential Savings Bank, a savings and loan association, which
may offer services  to the mortgagors  of the  Mortgage Loans. PHMC  is also  an
affiliate  of  Prudential  Residential  Services  Limited  Partnership  and  The
Prudential Real  Estate Affiliates,  Inc. (collectively,  "PRR"). PRR  primarily
offers  relocation  services to  corporate  employees and  residential brokerage
services to the public. PRR may, directly or through real estate brokers,  refer
loan  originations  to PHMC.  PHMC is  also an  affiliate of  a number  of other
insurance providers (including providers of life, health, disability, automobile
and personal catastrophe insurance) and financial services providers  (including
providers  of annuities,  mutual funds, retirement  accounts, financial planning
services,  credit  cards,  securities   and  commodities  brokerage  and   asset
management),  all of which may offer services  to the mortgagors of the Mortgage
Loans.
 
    PHMC conducts its  mortgage loan processing  through centralized  production
offices  located in Costa Mesa, California, Frederick, Maryland and Minneapolis,
Minnesota. At  these locations,  PHMC receives  applications for  home  mortgage
loans  on toll-free telephone  numbers that can  be called from  anywhere in the
United  States.  In  addition,  PHMC   maintains  marketing  offices  in   major
metropolitan centers in the United
 
                                       42
<PAGE>
States.  While the manner in  which it conducts its  business does not generally
entail face-to-face interactions  with borrowers,  PHMC has  varying degrees  of
direct  contact with  borrowers under  the mortgage  origination and acquisition
programs described below. Since PHMC takes a more active role in loan processing
in connection  with those  programs  that involve  the referral  of  applicants,
rather  than the purchase of completed  loan packages, borrower contact tends to
be more frequent where PHMC functions as the originator of the mortgage loans.
 
    On May 31, 1991, PHMC acquired  certain assets and operations of A  Mortgage
Company,  formerly America's  Mortgage Company ("AMC"),  located in Springfield,
Illinois. AMC's business consisted primarily of the origination and  acquisition
of  mortgage loans insured  or guaranteed by  the Federal Housing Administration
and the  United States  Department  of Veterans  Affairs ("FHA/VA  loans"),  the
issuance  and sale of securities guaranteed  by the Government National Mortgage
Association ("GNMA"), which securities were backed by pools of FHA/VA loans, and
the servicing of such mortgage loans.  These activities are now being  conducted
by  PHMC  from the  Springfield, Illinois  location.  The description  of PHMC's
activities elsewhere in this  Prospectus relate to  conventional rather than  to
FHA/VA  loans, since the Mortgage  Loans to be included  in the Trust Estate for
any Series of Certificates will be comprised exclusively of conventional loans.
 
MORTGAGE LOAN PRODUCTION SOURCES
 
    Unless otherwise specified in  the applicable Prospectus Supplement,  PHMC's
primary  sources  of mortgage  loans are  (i)  selected corporate  clients, (ii)
mortgage brokers and similar  entities, and (iii)  other originators. The  first
two  categories involve  the origination of  mortgage loans by  PHMC through the
referral of applicants  to PHMC by  the respective sources;  the third  category
involves  the acquisition by PHMC of qualifying mortgage loans presented to PHMC
by such third  parties. The relative  contribution of each  of these sources  to
PHMC's  business, measured by the volume  of loans generated, tends to fluctuate
over time.
 
    Mortgage loans generated  through contacts  with corporate  clients or  with
mortgage  brokers and similar entities typically  involve the referral of a loan
applicant  to  PHMC;  the  gathering  of  credit-related  and  property-specific
information  by PHMC; and  the decision by  PHMC, based on  its analysis of such
information, as to the suitability of its making the loan. It is  characteristic
of PHMC's practice with respect to loans generated as a result of referrals from
these  two sources  that PHMC, itself,  orders appraisals  (most frequently, the
original appraisals, but in some  cases, review appraisals) and credit  reports.
The  level of involvement  by PHMC in  other aspects of  the processing of these
loans varies considerably; whereas, PHMC typically assists the borrower referred
by corporate clients through the application  stage, PHMC tends to have  limited
contact  with those borrowers whose applications  are processed on PHMC's behalf
by certain mortgage brokers or similar entities, as discussed below. Taken as  a
whole, however, PHMC's processing role in connection with loans generated either
as  a result of  referrals from corporate  clients or from  mortgage brokers and
similar entities generally exceeds the  more limited processing role  associated
with  loans acquired from PHMC's third  production source, other originators. It
is PHMC's  practice  to review  the  loan file  submitted  to it  by  the  other
originator;  order  a new  credit report;  under certain  limited circumstances,
order a review appraisal;  and, on the  basis of its analysis  of both the  data
that  it has received  and the data  that it has  gathered, determine whether to
accept or reject the loan. For each  loan purchased by PHMC, the seller, or  the
other originator that previously sold the loan to PHMC's seller, will have taken
the  borrower's loan application,  obtained the initial  credit reports, ordered
the original appraisal and provided  all necessary documentation and  disclosure
relating  to compliance with federal, state  or local law applicable to mortgage
loan origination and servicing.
 
    A majority of PHMC's corporate clients are companies that sponsor relocation
programs for their employees and in connection with which PHMC provides mortgage
financing. Eligibility  for  a relocation  loan  is  based, in  general,  on  an
employer's   providing  financial  assistance  to  the  relocating  employee  in
connection with a job-required  move. Although all  Subsidy Loans are  generated
through  such  corporate-sponsored  programs,  the  assistance  extended  by the
employer need  not  necessarily  take the  form  of  a loan  subsidy.  (Not  all
relocation  loans are  generated by  PHMC through  referrals from  its corporate
clients: some relocation
 
                                       43
<PAGE>
loans are generated as a result  of referrals from mortgage brokers and  similar
entities; others are generated through PHMC's acquisition of mortgage loans from
other originators.) Also among PHMC's corporate clients are various professional
associations.  These  associations,  as  well as  the  other  corporate clients,
promote the availability  of a broad  range of PHMC  mortgage products to  their
members   or  employees,  including  refinance   loans,  second-home  loans  and
investment-property loans.
 
    Mortgage brokers, realtors (including  affiliates of Prudential  Insurance),
mortgage  bankers, commercial bankers, developers,  and builders also refer loan
applicants to PHMC.  Although the extent  to which mortgage  brokers or  similar
entities  will assist borrowers in  the application process varies considerably,
PHMC's role in the processing of  loans originated under this program  typically
involves the ordering of credit reports, as well as the ordering of the property
appraisal.  PHMC  may,  however,  permit certain  mortgage  brokers  and similar
entities to make  an initial determination  as to compliance  of mortgage  loans
with  PHMC's underwriting  guidelines. Under such  circumstances, the applicable
third parties take the loan  applications, obtain the borrowers' credit  reports
and  order  the property  appraisals from  qualified  appraisers. In  advance of
reaching a financing decision  with respect to such  loans, PHMC will  typically
order both review appraisals and additional credit reports.
 
    In  order  to qualify  for participation  in  PHMC's mortgage  loan purchase
programs, lending institutions must (i) meet and maintain certain net worth  and
other   financial   standards,  (ii)   demonstrate  experience   in  originating
residential  mortgage  loans,  (iii)  meet  and  maintain  certain   operational
standards,  (iv) evaluate each loan offered  to PHMC for consistency with PHMC's
underwriting guidelines and  (v) utilize the  services of qualified  appraisers.
The   contractual  arrangements  with  eligible   originators  may  involve  the
commitment by PHMC  to accept delivery  of a certain  dollar amount of  mortgage
loans over a period of time; this commitment may be satisfied either by delivery
of  mortgage loans  one at  a time or  in multiples  as aggregated  by the other
originator. In all instances, however, acceptance by PHMC is contingent upon the
loans being found  to satisfy PHMC's  program standards. PHMC  may also  acquire
portfolios of seasoned loans in negotiated transactions.
 
MORTGAGE LOAN UNDERWRITING
 
    In  determining  whether to  lend to  a particular  mortgage borrower  or to
purchase a mortgage loan, PHMC makes an assessment of the applicant's ability to
repay the loan, as well as an assessment  of the value of the property to  which
the  financing relates. The underwriting  standards that guide the determination
represent a balancing of several factors  that may affect the ultimate  recovery
of  the loan amount, including, among others,  the amount of the loan, the ratio
of the loan amount to the property value (i.e., the lower of the appraised value
of the  mortgaged property  and the  purchase price),  the borrower's  means  of
support  and the borrower's  credit history. PHMC's  guidelines for underwriting
may vary according  to the nature  of the borrower  or the type  of loan,  since
differing  characteristics may  be perceived  as presenting  different levels of
risk.
 
    PHMC's underwriting of  a mortgage  loan may be  based on  data obtained  by
parties  other than  PHMC that  are involved at  various stages  in the mortgage
origination or acquisition process. This typically occurs under circumstances in
which loans are subject to more  than one approval process, as when  third-party
lenders, certain mortgage brokers or similar entities that have been approved by
PHMC to process loans on its behalf, or independent contractors hired by PHMC to
perform  underwriting  services  on its  behalf  ("contract  underwriters") make
initial determinations as  to the  consistency of loans  with PHMC  underwriting
guidelines.   In  such  instances,   certain  information  may,   but  need  not
necessarily, be resolicited by PHMC in connection with its approval process. For
example, in connection with a mortgage loan that is presented to PHMC by another
originator for purchase, PHMC will typically  order a second credit report,  but
it  will only order  a review appraisal under  certain limited circumstances, in
advance of reaching a  purchase decision. However,  in connection with  mortgage
loans that are processed on PHMC's behalf by certain mortgage brokers or similar
entities,  PHMC will customarily order both a  second credit report and a review
appraisal. When contract underwriters  are used, PHMC  will generally not  order
any  supplemental  documentation but  will review  the information  collected by
these   providers,   who   are   trained    by   PHMC   personnel   in    PHMC's
 
                                       44
<PAGE>
underwriting  practices and are required to  review all loans in accordance with
PHMC's underwriting guidelines. In all cases, PHMC makes the final determination
to approve or deny the funding or purchase of a particular mortgage loan.
 
    The loan application elicits pertinent information about the applicant, with
particular emphasis on  the applicant's financial  health (assets,  liabilities,
income  and expenses), the property being financed and the type of loan desired.
A self-employed  applicant may  be required  to submit  his or  her most  recent
signed  federal  income tax  returns. With  respect  to every  applicant, credit
reports  are  obtained  from  commercial  reporting  services,  summarizing  the
applicant's  credit history with merchants  and lenders. Significant unfavorable
credit information reported by the applicant  or a credit reporting agency  must
be  explained by the applicant. The type of credit report that PHMC obtains, and
that  it  authorizes   parties  referring   loans  to   it  to   obtain,  is   a
computer-generated  report that  electronically merges  the information gathered
from  the  data  bases  of   two  major  consumer  credit  repositories   (these
repositories produce what are commonly referred to as "in-file" credit reports).
In  connection  with  its underwriting  procedure,  PHMC will,  with  the single
exception of the use of contract  underwriters, itself order a credit report  of
the  type described, whether  or not a  report has previously  been ordered with
respect to an applicant for whom another party has processed or approved of  the
loan. Certain of the credit reports that PHMC obtains may be purchased through a
credit reporting service with which LSI has a contractual relationship.
 
    Verifications  of employment,  income, assets  or mortgages  may be  used to
supplement  the  loan  application   and  the  credit   report  in  reaching   a
determination  as  to  the  applicant's  ability  to  meet  his  or  her monthly
obligations on the proposed mortgage loan, as well as his or her other  mortgage
payments  (if  any),  living  expenses  and  financial  obligations.  A mortgage
verification involves  obtaining information  regarding the  borrower's  payment
history  with  respect to  any existing  mortgage the  applicant may  have. This
verification is  accomplished by  either having  the present  lender complete  a
verification  of mortgage form, evaluating the  information on the credit report
concerning  the  applicant's   payment  history  for   the  existing   mortgage,
communicating,  either  verbally or  in  writing, with  the  applicant's present
lender or analyzing cancelled checks provided by the applicant. Verifications of
income, assets or  mortgages may  be waived  under certain  programs offered  by
PHMC, but PHMC's practice is to obtain verification of employment for every loan
applicant.   Waivers  limit  the   amount  of  documentation   required  for  an
underwriting decision and have the effect of increasing the relative  importance
of  the credit report  and the appraisal.  Such waivers or reduced-documentation
options are, in general, available for owner-occupied properties where the ratio
of the loan amount to the property value does not exceed 80%. The interest  rate
may  be higher with  respect to a loan  which has been  processed according to a
reduced documentation program than a loan which has been processed under a  full
documentation  program. Documentation requirements  vary based upon  a number of
factors, including the purpose of the loan, the amount of the loan and the ratio
of  the   loan   amount  to   the   property  value.   The   least   restrictive
reduced-documentation  programs apply to the applicant for a relocation loan and
to the borrower whose  loan amount does not  exceed $600,000 and whose  Loan-to-
Value  Ratio  is not  in  excess of  75%.  PHMC accepts  alternative  methods of
verification,  in  those   instances  where  verifications   are  part  of   the
underwriting  decision; for example, salaried income may be substantiated either
by means of a form independently prepared and signed by the applicant's employer
or by means of the applicant's most  recent paystub and W-2. In cases where  two
or  more persons have jointly applied for a mortgage loan, the gross incomes and
expenses of  all of  the applicants,  including nonoccupant  co-mortgagors,  are
combined and considered as a unit.
 
    All borrowers applying for relocation loans, as well as borrowers affiliated
with professional associations applying for loans with Loan-to-Value Ratios less
than  or  equal to  80%,  and all  other  borrowers applying  for non-relocation
mortgage loans with respect to which  the Loan-to-Value Ratios are less than  or
equal  to 75%, generally must demonstrate that  the ratio of their total monthly
housing debt to their  monthly gross income  does not exceed  33%, and that  the
ratio  of their total monthly debt to their monthly gross income does not exceed
38%;  borrowers   affiliated  with   professional  associations   applying   for
non-relocation  mortgage loans with  Loan-to-Value Ratios in  excess of 80%, and
all  other   borrowers  applying   for   non-relocation  mortgage   loans   with
Loan-to-Value  Ratios  in excess  of  75%, generally  must  satisfy 28%  and 36%
ratios, respectively.
 
                                       45
<PAGE>
These calculations are based on the amortization schedule and the interest  rate
of the related loan, with each ratio being computed on the basis of the proposed
monthly  mortgage payment.  In the case  of adjustable-rate  mortgage loans, the
interest rate used to  determine a mortgagor's monthly  payment for purposes  of
the  foregoing ratios is the initial  mortgage interest rate, which is generally
lower than the sum of the index  that would have been applicable at  origination
plus  the applicable  margin. In evaluating  applications for  Subsidy Loans and
Buy-Down Loans,  the  foregoing  ratios  are  determined  by  including  in  the
applicant's  total monthly housing  expense and total  monthly debt the proposed
monthly mortgage  payment reduced  by the  amount expected  to be  applied on  a
monthly  basis under the related subsidy  agreement or buy-down agreement or, in
certain cases, the  mortgage payment  that would  result from  an interest  rate
approximately  2.50%  lower  than the  Mortgage  Interest Rate.  See  "The Trust
Estates--Mortgage Loans." These ratios may  be exceeded if, in PHMC's  judgment,
certain  compensating  factors are  identified and  proved to  its satisfaction,
including a  large downpayment,  a  large equity  position  on a  refinance,  an
excellent  credit history,  substantial liquid net  worth, the  potential of the
borrower for continued employment advancement  or income growth, or the  ability
of the borrower to accumulate assets or to devote a greater portion of income to
basic  needs  such  as  housing expense.  Secondary  financing  is  permitted on
mortgage  loans  under  certain  circumstances.  In  those  cases,  the  payment
obligations  under  both primary  and secondary  financing  are included  in the
computation of  the  debt-to-income ratios  described  above, and  the  combined
amount   of  primary  and  secondary  loans   will  be  used  to  calculate  the
Loan-to-Value Ratio.  Any secondary  financing permitted  will generally  mature
prior  to  the maturity  date of  the  related mortgage  loan. In  evaluating an
application with respect to a "non-owner-occupied" property, which PHMC  defines
as  a property leased to a third party  by its owner (as distinct from a "second
home," which PHMC defines as an owner-occupied, non-rental property that is  not
the  owner's principal residence), PHMC will permit projected rental income from
such property  to  be  included  in the  applicant's  monthly  gross  income  if
necessary  to satisfy the foregoing ratios. A mortgage loan secured by a two- to
four-family Mortgaged Property is considered to be an owner-occupied property if
the borrower occupies  one of the  units; rental  income on the  other units  is
generally  taken into account in evaluating  the borrower's ability to repay the
mortgage loan.
 
    Property value  is established  in connection  with the  origination of  any
mortgage  loan  (whether  the loan  is  originated for  purchase  or refinancing
purposes) by means  of an  appraisal, which is  typically ordered  by the  party
originating  the  related  mortgage  loan. Consistent  with  this  practice, the
appraisals with respect  to the  loans generated through  corporate contacts  or
through  referrals from mortgage  brokers or other  similar entities (other than
those certain mortgage brokers or  similar entities that process mortgage  loans
on  PHMC's  behalf) are  generally ordered  by PHMC,  while the  appraisals with
respect to the loans sold  to PHMC by third-party  lenders are ordered by  those
other originators. PHMC may, however, at it discretion, order a review appraisal
with  respect to any loan  generated by a third-party  lender; in addition, PHMC
typically orders review appraisals with  respect to loans that certain  mortgage
brokers  or similar entities process on its behalf. A review appraisal, like the
original appraisal,  involves  the  making  of  a  site  visit,  the  taking  of
photographs, and the gathering of data on comparable properties. Unlike original
appraisals,  however,  review appraisals  do not  include  an inspection  of the
interior of the  house. A  review appraisal is  generally used  to validate  the
decision  made based  upon the original  appraisal. If the  variance between the
original and the review appraisal is significant, an explanation will be  sought
and  the underwriting decision  may be reevaluated.  In certain instances, which
most frequently  involve the  postponement  of the  closing  with respect  to  a
mortgage   loan  on  a  newly  built   home  due  to  construction  delays,  the
recertification of an appraisal  may be required.  A recertification includes  a
physical  inspection  of the  exterior of  the  property and  a statement  by an
appraiser that the present value of the property is no lower than that reflected
on the original appraisal.
 
    There can be no assurance that the values determined by the appraisers as of
the dates  of appraisal  represent the  prices at  which the  related  Mortgaged
Properties  can be sold, either as of  the dates of appraisal or at foreclosure.
The appraisal  of any  Mortgaged Property  reflects the  individual  appraiser's
judgment as to value, based on the market values of comparable homes sold within
the  recent past in comparable nearby locations and on the estimated replacement
cost. The appraisal relates both  to the land and to  the structure; in fact,  a
significant  portion  of the  appraised  value of  a  Mortgaged Property  may be
 
                                       46
<PAGE>
attributable to the value of the land  rather than to the residence. Because  of
the  unique  locations and  special  features of  certain  Mortgaged Properties,
identifying comparable  properties in  nearby locations  may be  difficult.  The
appraised  values of such Mortgaged Properties will be based to a greater extent
on adjustments made  by the  appraisers to  the appraised  values of  reasonably
similar  properties rather than  on objectively verifiable  sales data. See "The
Trust Estates--Mortgage Loans" herein.
 
    In connection with  all mortgage  loans that it  originates, PHMC  currently
obtains appraisals through LSI. Review appraisals with respect to mortgage loans
that  PHMC acquires, or with respect to  mortgage loans that PHMC originates but
that certain mortgage  brokers or similar  entities process on  its behalf,  are
also  likely  to be  obtained through  LSI.  LSI also  provides its  services to
third-party lenders which sell mortgage loans to PHMC.
 
    Most residential mortgage  lenders have not  originated mortgage loans  with
Loan-to-Value  Ratios in  excess of  80% unless  primary mortgage  insurance was
obtained. PHMC, however, does not require primary mortgage insurance on loans up
to $400,000 that have Loan-to-Value Ratios exceeding 80% but less than or  equal
to  90%.  Only owner-occupied,  primary  residences (excluding  cooperatives and
certain high-rise condominium  dwellings) are  eligible for  this program.  Each
qualifying  loan will be made  at an interest rate that  is higher than the rate
would be if  the Loan-to-Value  Ratio was  80% or  less or  if primary  mortgage
insurance  was  obtained. Loans  that do  not  qualify for  such program  may be
approved if  primary mortgage  insurance is  obtained from  an approved  primary
mortgage  insurance company. In such cases, the  excess over 75% will be covered
by primary mortgage insurance until the unpaid principal balance of the Mortgage
Loan is reduced to an amount that will result in a Loan-to-Value Ratio less than
or equal to 80%.
 
    Where permitted by law, PHMC generally  requires that a borrower include  in
each  monthly payment a  portion of the real  estate taxes, assessments, primary
mortgage insurance  (if applicable),  and hazard  insurance premiums  and  other
similar items with respect to the related mortgage loan. PHMC may, however, on a
case-by-case  basis, in  its discretion  not require  such advance  payments for
certain Mortgage Loans, based on an evaluation of the borrowers' ability to  pay
such taxes and charges as they become due.
 
MORTGAGE ORIGINATION PROCESSING
 
    PHMC,  or  an  affiliate  of PHMC,  may  provide  loan  processing services,
including document preparation, underwriting analysis and closing functions,  to
other  loan originators. It is  possible that PHMC may  purchase loans from such
loan originators,  or  from mortgage  sellers  that purchased  loans  from  such
originators,  that PHMC itself processed. Any  such loans purchased by PHMC will
meet PHMC's underwriting guidelines.
 
SERVICING
 
    Prior to  June  30,  1989,  all residential  mortgage  loans  originated  or
purchased by PHMC for its own account or for the account of Prudential Insurance
were  serviced by its affiliate, PMCC. On June 30, 1989, PHMC assumed all of the
residential mortgage servicing activities then  being performed by PMCC. On  May
31,  1991, PHMC entered into a Subservicing Agreement with AMC pursuant to which
PHMC  will  sub-service  AMC's  current   servicing  portfolio  of  FHA/VA   and
conventional  loans. PHMC is an approved servicer of FNMA, FHLMC and GNMA. As of
December 31,  1991, PHMC  had a  net worth  of approximately  $213 million.  See
"Servicing of the Mortgage Loans--The Servicer" below.
 
                                USE OF PROCEEDS
 
    The  net proceeds from the sale of  each Series of Certificates will be used
by the  Seller  for  the purchase  of  the  Mortgage Loans  represented  by  the
Certificates  of such Series  from PHMC. It  is expected that  PHMC will use the
proceeds from the  sale of  the Mortgage  Loans to  the Seller  for its  general
business purposes, including, without limitation, the origination or acquisition
of  new mortgage loans and  the repayment of borrowings  incurred to finance the
origination or  acquisition  of mortgage  loans,  including the  Mortgage  Loans
underlying the Certificates of such Series.

                        SERVICING OF THE MORTGAGE LOANS
 
THE SERVICER
 
    The  Servicer with  respect to  a Series of  Certificates will  be PHMC. See
"PHMC--Servicing" above. The Servicer may subcontract its servicing  obligations
under  any Pooling and  Servicing Agreement. The  Servicer will remain primarily
liable for any such subservicer's performance in accordance with the  applicable
Pooling  and  Servicing  Agreement.  The  Servicer  may  be  released  from  its
obligations  in   certain  circumstances.   See  "Servicing   of  the   Mortgage
Loans--Certain Matters Regarding the Servicer."
 
    Each Prospectus Supplement relating to a Series of Certificates will contain
information  concerning recent delinquency, foreclosure and loan loss experience
on the  mortgage  loans  included  in  PHMC's  servicing  portfolio  which  were
originated  or acquired by  PHMC for its own  account or for  the account of its
affiliates ("Program Loans"), and, if  available, on those Program Loans  having
payment  terms generally similar to  those of the Mortgage  Loans in the related
Trust Estate. PHMC's total servicing portfolio  of Program Loans as of any  date
may  include  loans  having  a  variety  of  payment  characteristics, including
adjustable rate mortgage loans and loans subject to subsidy agreements, and  the
overall  delinquency, foreclosure and loan loss  experience of the Program Loans
taken as a whole  may differ from  that of the Mortgage  Loans contained in  any
given Trust Estate and from that of mortgage servicers generally.
 
PAYMENTS ON MORTGAGE LOANS
 
    The Servicer will, as to each Series of Certificates, establish and maintain
a  separate  trust  account  or  accounts  in  the  name  of  the  Trustee  (the
"Certificate Account"), which must be  maintained with a depository  institution
(the "Depository") acceptable to the Rating Agency or Rating Agencies rating the
Certificates  of  such  Series. Such  account  or  accounts will  be  either (i)
maintained with a Depository whose long-term debt obligations at the time of any
deposit therein are rated  not lower than  the rating on  the related Series  of
Certificates  at the time of the initial  issuance thereof or (ii) fully insured
by the Federal  Deposit Insurance  Corporation (the "FDIC")  through either  the
Bank  Insurance Fund or the Savings Association Insurance Fund, (iii) insured by
the FDIC (to the limit established by the FDIC), the uninsured deposits in which
accounts are otherwise secured such that, as evidenced by an opinion of counsel,
the Trustee of  the related  Series has  a claim with  respect to  funds in  the
Certificate  Account for  such Series, or  a perfected security  interest in any
collateral securing such  funds, that  is superior to  the claims  of any  other
depositor  or  general creditor  of the  Depository  with which  the Certificate
Account is  maintained or  (iv) such  other account  that is  acceptable to  the
Rating  Agency or Rating Agencies rating the Certificates of such Series and, if
a REMIC election has been  made, that would not  cause the related Trust  Estate
(or a segregated pool of assets therein) to fail to qualify as a REMIC.
 
    The  Servicer will  deposit in  the Certificate  Account for  each Series of
Certificates any  amounts  representing  scheduled  payments  of  principal  and
interest  on  the  Mortgage Loans  due  after  the applicable  Cut-Off  Date but
received on or prior thereto, and, on a daily basis, except as specified in  the
applicable   Pooling  and  Servicing  Agreement,   the  following  payments  and
collections received or made by it with respect to the Mortgage Loans subsequent
to the applicable Cut-Off Date (other than payments due on or before the Cut-Off
Date):
 
         (i) all payments  on account of  principal, including prepayments,  and
    interest;
 
        (ii)  all  amounts  received  by the  Servicer  in  connection  with the
    liquidation of  defaulted Mortgage  Loans or  property acquired  in  respect
    thereof,  whether through foreclosure sale  or otherwise, including payments
    in connection  with defaulted  Mortgage Loans  received from  the  mortgagor
    other  than amounts  required to  be paid to  the mortgagor  pursuant to the
    terms  of  the  applicable  Mortgage  Loan  or  otherwise  pursuant  to  law
    ("Liquidation  Proceeds") less, to the extent permitted under the applicable
    Pooling and  Servicing Agreement,  the amount  of any  expenses incurred  in
    connection with the liquidation of such Mortgage Loans;
 
                                       48
<PAGE>
        (iii)  all proceeds received by the  Servicer under any title, hazard or
    other insurance policy covering any such Mortgage Loan, other than  proceeds
    to  be applied to the  restoration or repair of  the property subject to the
    related Mortgage  or  released  to  the mortgagor  in  accordance  with  the
    applicable Pooling and Servicing Agreement;
 
        (iv)  all  amounts required  to be  deposited  therein from  any related
    Reserve  Fund,  and  amounts  available  under  any  other  form  of  credit
    enhancement applicable to such Series;
 
        (v) all Periodic Advances made by the Servicer;
 
        (vi) all amounts withdrawn from Buy-Down Funds or Subsidy Funds, if any,
    with  respect to such  Mortgage Loans, in  accordance with the  terms of the
    respective agreements applicable thereto;
 
       (vii) all proceeds  of any such  Mortgage Loans or  property acquired  in
    respect  thereof  purchased  or  repurchased  pursuant  to  the  Pooling and
    Servicing Agreement; and
 
       (viii) all other amounts required to be deposited therein pursuant to the
    applicable Pooling and Servicing Agreement.
 
    Notwithstanding the  foregoing,  the  Servicer  will  be  entitled,  at  its
election,  either (a)  to withhold and  pay itself the  applicable Servicing Fee
and/or to withhold and  pay to the  owner thereof the  Fixed Retained Yield,  if
any,  from any payment or other recovery  on account of interest as received and
prior to deposit in  the Certificate Account or  (b) to withdraw the  applicable
Servicing  Fee and/or  the Fixed  Retained Yield,  if any,  from the Certificate
Account after  the  entire  payment  or recovery  has  been  deposited  therein;
provided,  however, that with respect to each Trust Estate (or a segregated pool
of assets therein)  as to which  a REMIC  election has been  made, the  Servicer
will, in each instance, withhold and pay to the owner thereof the Fixed Retained
Yield  prior to deposit  of the related  payment or recovery  in the Certificate
Account.
 
    Periodic Advances,  amounts  withdrawn from  any  Buy-Down Fund  or  Subsidy
Account,  amounts withdrawn from  any reserve fund,  and amounts available under
any other  form of  credit enhancement,  will be  deposited in  the  Certificate
Account not later than the business day preceding the Distribution Date on which
such amounts are required to be distributed. All other amounts will be deposited
in  the Certificate Account not  later than the business  day next following the
day of receipt and posting by the Servicer.
 
    If the Servicer deposits in the Certificate Account for a Series any  amount
not  required to be deposited  therein, it may at  any time withdraw such amount
from such Certificate Account. Funds on  deposit in the Certificate Account  may
be  invested in certain Eligible Investments  maturing in general not later than
the business day  preceding the  next Distribution Date.  In the  event that  an
election has been made to treat the Trust Estate (or a segregated pool of assets
therein)  with respect to a Series as a REMIC, no such Eligible Investments will
be sold or  disposed of  at a  gain prior to  maturity unless  the Servicer  has
received  an opinion of counsel  or other evidence satisfactory  to it that such
sale or  disposition will  not cause  the Trust  Estate (or  segregated pool  of
assets)  to be subject to  the tax on "prohibited  transactions" imposed by Code
Section 860F(a)(1), otherwise subject  the Trust Estate  (or segregated pool  of
assets) to tax, or cause the Trust Estate (or segregated pool of assets) to fail
to  qualify  as  a  REMIC.  Except  as  otherwise  specified  in  the applicable
Prospectus Supplement, all  income and  gain realized from  any such  investment
will be for the account of the Servicer as additional servicing compensation and
all  losses from any such investment will  be deposited by the Servicer into the
Certificate Account immediately as realized.
 
    The Servicer is permitted, from time  to time, to make withdrawals from  the
Certificate  Account for the following purposes,  to the extent permitted in the
applicable Pooling and Servicing Agreement:
 
         (i) to reimburse itself for Periodic Advances;
 
        (ii) to  reimburse  itself  for liquidation  expenses  and  for  amounts
    expended by it in connection with the restoration of damaged property;
 
                                       49
<PAGE>
        (iii) to pay to itself the applicable Servicing Fee and/or pay the owner
    thereof any Fixed Retained Yield, in the event the Servicer is not required,
    and  has elected not, to  withhold such amounts out  of any payment or other
    recovery with respect to a particular Mortgage Loan prior to the deposit  of
    such payment or recovery in the Certificate Account;
 
        (iv)  to reimburse itself for certain  expenses (including taxes paid on
    behalf of the Trust Estate) incurred  by and recoverable by or  reimbursable
    to it;
 
        (v)  to pay to the Seller with respect to each Mortgage Loan or property
    acquired in respect  thereof that has  been repurchased by  the Seller,  all
    amounts  received thereon and not distributed as of the date as of which the
    purchase price of such Mortgage Loan was determined;
 
        (vi) to pay itself  any interest earned on  or investment income  earned
    with  respect  to funds  in the  Certificate Account  (all such  interest or
    income to be withdrawn not later than the next Distribution Date);
 
       (vii) to pay itself from net Liquidation Proceeds allocable to  interest,
    the amount of any unpaid Servicing Fees and any unpaid assumption fees, late
    payment charges or other mortgagor charges on the related Mortgage Loan;
 
       (viii)  to withdraw from the Certificate  Account any amount deposited in
    the Certificate Account that was not required to be deposited therein;
 
        (ix) to make withdrawals from the  Certificate Account in order to  make
    distributions to Certificateholders; and
 
        (x) to clear and terminate the Certificate Account.
 
    The  Servicer  will be  authorized to  appoint a  paying agent  (the "Paying
Agent") to make distributions, as agent for the Servicer, to  Certificateholders
of  a Series. If  the Paying Agent for  a Series is the  Trustee of such Series,
such Paying Agent will  be authorized to make  withdrawals from the  Certificate
Account  in order  to make  distributions to  Certificateholders. If  the Paying
Agent for a Series is not the Trustee for such Series, the Servicer will,  prior
to  each Distribution Date, deposit in immediately available funds in an account
designated by the  Paying Agent  the amount required  to be  distributed to  the
Certificateholders on such Distribution Date.
 
    The Servicer will cause any Paying Agent which is not the Trustee to execute
and  deliver to the Trustee an instrument in which such Paying Agent agrees with
the Trustee that such Paying Agent will:
 
        (1) hold all amounts deposited with it by the Servicer for  distribution
    to  Certificateholders in trust for  the benefit of Certificateholders until
    such amounts are distributed to Certificateholders or otherwise disposed  of
    as provided in the applicable Pooling and Servicing Agreement;
 
        (2) give the Trustee notice of any default by the Servicer in the making
    of such deposit; and
 
        (3) at any time during the continuance of any such default, upon written
    request  of the Trustee,  forthwith pay to  the Trustee all  amounts held in
    trust by such Paying Agent.
 
PERIODIC ADVANCES AND LIMITATIONS THEREON
 
    With respect  to each  Series,  the Servicer  will  agree to  make  Periodic
Advances in the amounts specified in the applicable Prospectus Supplement. Funds
of  the Servicer  so advanced  are recoverable  by the  Servicer out  of amounts
received on Mortgage Loans  with respect to which  such funds were advanced  and
which  represent late recoveries  of principal and/or  interest respecting which
any such Periodic  Advance was  made, or, if  the Servicer  determines that  any
Periodic  Advance may not be so recoverable, out of any funds in the Certificate
Account. The Servicer  will make Periodic  Advances only if  it determines  that
funds  will  ultimately  be  available  to reimburse  it.  If  specified  in the
applicable Prospectus Supplement, a reserve fund
 
                                       50
<PAGE>
may be  established with  respect to  any  Series of  Certificates in  order  to
provide  a source of liquidity  for Periodic Advances by  the Servicer. Any such
reserve fund will be funded by a deposit made by the Servicer in such an  amount
specified,  and will  otherwise be  as described,  in the  applicable Prospectus
Supplement.
 
ADJUSTMENT TO SERVICING FEE IN CONNECTION WITH PREPAID AND LIQUIDATED MORTGAGE
LOANS
 
    When a mortgagor prepays all of a Mortgage Loan, the mortgagor pays interest
on the amount prepaid only to the date on which the principal prepayment in full
is made.  Similarly, Liquidation  Proceeds from  a Mortgaged  Property will  not
include  interest for any  period after the  date on which  the liquidation took
place, and  insurance  proceeds  may  include  interest  only  to  the  date  of
settlement  of the related claims.  Further, when a Mortgage  Loan is prepaid in
part, and  such prepayment  is applied  as of  a date  other than  the Due  Date
occurring  in  the month  of  receipt or  the Due  Date  occurring in  the month
following the  month of  receipt,  the mortgagor  pays  interest on  the  amount
prepaid  only to  the date  of prepayment  and not  thereafter. Unless otherwise
specified in  the applicable  Prospectus Supplement,  in order  to mitigate  the
adverse  effect to Certificateholders of a  Series resulting from the prepayment
in full or liquidation of  a Mortgage Loan or  settlement of an insurance  claim
with  respect thereto, the amount of the aggregate Servicing Fees will be offset
by an amount equal to the accrual of interest on any fully prepaid or liquidated
Mortgage Loan at the Net Mortgage Interest Rate for such Mortgage Loan from  the
date  of its prepayment or liquidation or  the date of such insurance settlement
to but not including  the next Due Date  (the "Prepayment Interest  Shortfall").
Such  reductions in the  aggregate Servicing Fees  will be made  by the Servicer
with respect to the  Mortgage Loans under the  applicable Pooling and  Servicing
Agreement,  but  only  to  the extent  that  the  aggregate  Prepayment Interest
Shortfall does not exceed the aggregate amount of the Servicing Fee relating  to
mortgagor  payments or other recoveries  distributed on the related Distribution
Date. The amount  of the  offset against the  aggregate Servicing  Fees will  be
included  in the distributions to Certificateholders on the Distribution Date on
which the  related  principal  prepayments  in  full,  Liquidation  Proceeds  or
insurance  proceeds are  passed through to  Certificateholders. Unless otherwise
specified in  the  applicable  Prospectus  Supplement,  any  interest  shortfall
arising  from application by the Servicer of partial prepayments other than on a
Due Date will be borne solely  by Certificateholders of the related Series.  See
"Prepayment  and  Yield  Considerations." Payments  of  the  Prepayment Interest
Shortfall or Curtailment Interest Shortfall will not be obtained by means of any
subordination of  the rights  of Subordinated  Certificateholders or  any  other
credit enhancement arrangement.
 
REPORTS TO CERTIFICATEHOLDERS
 
    Unless  otherwise specified or modified in the related Pooling and Servicing
Agreement for each Series, the Servicer will include, or, in the event a  Paying
Agent  has been  appointed with  respect to such  Series, will  cause the Paying
Agent to include, with each distribution to Certificateholders of record of such
Series a statement setting forth the following information, if applicable:
 
         (i)  to  each  holder  of  a  Certificate  other  than  a   Multi-Class
    Certificate,  the amount of such distribution  allocable to principal of the
    related Mortgage Loans, separately identifying  the aggregate amount of  any
    principal  prepayments  included therein,  the  amount of  such distribution
    allocable to interest on the related Mortgage Loans and the aggregate unpaid
    principal balance of the Mortgage Loans evidenced by each Class after giving
    effect to the principal distributions on such Distribution Date;
 
        (ii) to each holder  of a Multi-Class Certificate  on which an  interest
    distribution and a distribution in reduction of Stated Amount are then being
    made, the amount of such interest distribution and distribution in reduction
    of Stated Amount, and the Stated Amount of each Class after giving effect to
    the  distribution in  reduction of Stated  Amount made  on such Distribution
    Date;
 
        (iii)  to  each  holder  of   a  Multi-Class  Certificate  on  which   a
    distribution  of  interest only  is then  being  made, the  aggregate Stated
    Amount of Certificates outstanding of each Class after giving effect to  the
    distribution  in reduction of  Stated Amount made  on such Distribution Date
    and on any Special Distribution Date  occurring subsequent to the last  such
    report and after including in the aggregate Stated
 
                                       51
<PAGE>

    outstanding and  the amount  of any  accrued interest  added to  the  Stated
    Amount of such Compound Interest Certificates on such Distribution Date;
 
        (iv)  to each  holder of a  Multi-Class Certificate which  is a Compound
    Interest Certificate (but  only if  such holder  shall not  have received  a
    distribution  of interest equal to the  entire amount of interest accrued on
    such Certificate with respect to such Distribution Date):
 
           (a) the information  contained in  the report  delivered pursuant  to
       clause (ii) above;
 
           (b)   the  interest  accrued  on  such  Class  of  Compound  Interest
       Certificates with  respect to  such Distribution  Date and  added to  the
       Stated Amount of such Compound Interest Certificate; and
 
           (c) the Stated Amount of such Class of Compound Interest Certificates
       after  giving  effect to  the addition  thereto  of all  interest accrued
       thereon;
 
        (v)  to  each  holder  of   a  Certificate,  the  amount  of   servicing
    compensation  with  respect  to  the related  Trust  Estate  and  such other
    customary information as the Servicer deems necessary or desirable to enable
    Certificateholders to prepare their tax returns;
 
        (vi) to each holder of a Certificate, the amount by which the  Servicing
    Fee  has been reduced by the aggregate Prepayment Interest Shortfall for the

       (vii) the  aggregate amount  of  any Periodic  Advances by  the  Servicer
    included in the amounts actually distributed to the Certificateholders;
 
       (viii)  to each holder of each  Senior Certificate (other than a Shifting
    Interest Certificate):
 
           (a)  the  amount  of  funds,  if  any,  otherwise  distributable   to
       Subordinated Certificateholders and the amount of any withdrawal from the
       Subordination  Reserve Fund  included in amounts  actually distributed to
       Senior Certificateholders;
 
           (b)  the  Subordinated  Amount  remaining  and  the  balance  in  the
       Subordination Reserve Fund following such distribution; and
 
           (c) the amount of any Senior Class Shortfall with respect to, and the
       amount of any Senior Class Carryover Shortfall outstanding prior to, such
       Distribution Date;
 
        (ix)  to  each  holder of  a  Certificate  entitled to  the  benefits of
    payments under any form of credit enhancement or from any reserve fund other
    than the Subordination Reserve Fund:
 
           (a) the  amounts  so  distributed  under  any  such  form  of  credit
       enhancement  or from any such reserve fund on the applicable Distribution
       Date; and
 
           (b) the amount of  coverage remaining under any  such form of  credit
       enhancement  and the balance in any such fund, after giving effect to any
       payments thereunder and other amounts charged thereto on the Distribution
       Date;
 
        (x) in the case of a Series of Certificates with a variable Pass-Through
    Rate, such Pass-Through Rate;
 
        (xi) the  book value  of any  collateral acquired  by the  Trust  Estate
    through foreclosure or otherwise;
 
        (xii)  the unpaid principal balance of any Mortgage Loan as to which the

       (xiii) the number and  aggregate principal amount  of Mortgage Loans  one
    month, two months and three or more months delinquent.

    In  addition,  within a  reasonable period  of  time after  the end  of each
calendar year, the Servicer will furnish either directly, or through the  Paying
Agent,  if any, a report to each  Certificateholder of record at any time during
such calendar year (a) as to the  aggregate of amounts reported pursuant to  (i)
and  (ii) above,  as applicable, 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  information  as
required  by the Code and applicable  regulations thereunder and as the Servicer
deems necessary or desirable to  enable Certificateholders to prepare their  tax
returns.  (Section 4.02.) In the  event that an election  has been made to treat
the Trust  Estate (or  a segregated  pool of  assets therein)  as a  REMIC,  the
Trustee  will be required  to sign the  Federal income tax  returns of the REMIC
(which will  be prepared  by  the Servicer).  See  "Certain Federal  Income  Tax
Consequences--Federal  Income Tax Consequences for REMIC Certificates-- Taxation
of Residual Certificates--Administrative Matters."
 
REPORTS TO THE TRUSTEE
 
    No later  than  15 days  after  each Distribution  Date  for a  Series,  the
Servicer will provide the Trustee of such Series with a report setting forth the
status  of the related Certificate Account and the related Subordination Reserve
Fund and any other reserve fund as of the close of business on such Distribution
Date, stating that all distributions required  to be made by the Servicer  under
the  applicable  Pooling  and Servicing  Agreement  have  been made  (or  if any
required distribution has not been made  by the Servicer, specifying the  nature
and  status thereof) and showing, for the  period covered by such statement, the
aggregate of deposits to and withdrawals  from the Certificate Account for  each
category  of deposits  and withdrawals  specified in  the Pooling  and Servicing
Agreement. Such statement shall also include information as to (i) the aggregate
unpaid principal balances of all the Mortgage Loans as of the close of  business
on the last day of the month preceding the month in which such Distribution Date
occurs;  and (ii)  the amount  of any Subordination  Reserve Fund  and any other
reserve fund,  as  of  such  Distribution  Date  (after  giving  effect  to  the
distributions on such Distribution Date). Copies of such reports may be obtained
by Certificateholders upon request in writing addressed to the Servicer, c/o The
Prudential  Home  Mortgage Company,  Inc., 7470  New Technology  Way, Frederick,
Maryland 21701. If the Servicer should fail to provide such copies, they may  be
obtained from the Trustee. (Section 3.12).
 
COLLECTION AND OTHER SERVICING PROCEDURES
 
    The Servicer will make reasonable efforts to collect all payments called for
under  the Mortgage Loans  and will, consistent with  the applicable Pooling and
Servicing Agreement and any  applicable agreement governing  any form of  credit
enhancement,  follow such  collection procedures as  it follows  with respect to
mortgage loans  serviced  by it  that  are  comparable to  the  Mortgage  Loans.
Consistent  with the above, the  Servicer may, in its  discretion, (i) waive any
prepayment charge, assumption fee,  late payment charge or  any other charge  in
connection  with  the prepayment  of a  Mortgage  Loan and  (ii) arrange  with a
mortgagor a schedule for  the liquidation of deficiencies  running for not  more
than 180 days after the applicable Due Date.
 
    Under  the  Pooling and  Servicing Agreement,  the  Servicer, to  the extent
permitted by law, will establish and  maintain one or more escrow accounts  (the
"Servicing  Account")  in which  the Servicer  will be  required to  deposit any
payments made by mortgagors in advance for taxes, assessments, primary  mortgage
(if   applicable)  and  hazard  insurance  premiums  and  other  similar  items.
Withdrawals from the Servicing Account may  be made to effect timely payment  of
taxes,  assessments,  mortgage and  hazard  insurance, to  refund  to mortgagors
amounts determined to be overages, to pay interest to mortgagors on balances  in
the Servicing Account, if required, and to clear and terminate such account. The
Servicer  will be responsible for the  administration of each Servicing Account.
The Servicer will be obligated to  advance certain amounts which are not  timely
paid  by the mortgagors, to  the extent that it  determines, in good faith, that
they will be  recoverable out  of insurance proceeds,  liquidation proceeds,  or
otherwise.  Alternatively,  in lieu  of  establishing a  Servicing  Account, the
Servicer may procure a performance bond or other form of insurance coverage,  in
an  amount  acceptable  to  the  Rating  Agency  rating  the  related  Series of
Certificates, covering loss occasioned  by the failure  to escrow such  amounts.
(Section 3.06.)

ENFORCEMENT OF DUE-ON-SALE CLAUSES; REALIZATION UPON DEFAULTED MORTGAGE LOANS
 
    With  respect to  each Mortgage  Loan having  a fixed  interest rate, unless
otherwise specified in  the applicable Prospectus  Supplement, each Pooling  and
Servicing  Agreement will provide that, when  any Mortgaged Property is about to
be conveyed by the mortgagor, the Servicer will, to the extent it has  knowledge
of  such prospective conveyance, exercise its  rights to accelerate the maturity
of such Mortgage Loan under the "due-on-sale" clause applicable thereto, if any,
unless it is  not exercisable  under applicable law  or if  such exercise  would
result  in loss  of insurance  coverage with  respect to  such Mortgage  Loan or
would, in the Servicer's judgment, be reasonably likely to result in  litigation
by  the mortgagor. In either  case, the Servicer is  authorized to take or enter
into an assumption and  modification agreement from or  with the person to  whom
such  Mortgaged Property has been or is  about to be conveyed, pursuant to which
such person becomes  liable under the  Mortgage Note and,  unless prohibited  by
applicable  state law, the  mortgagor remains liable  thereon, provided that the
Mortgage Loan will continue to be covered  by any pool insurance policy and  any
related  primary mortgage insurance  policy and the  Mortgage Interest Rate with
respect to such Mortgage Loan and the payment terms shall remain unchanged.  The
Servicer  will also be authorized,  with the prior approval  of the pool insurer
and the  primary mortgage  insurer, if  any,  to enter  into a  substitution  of
liability  agreement with such person, pursuant  to which the original mortgagor
is released  from liability  and such  person is  substituted as  mortgagor  and
becomes liable under the Mortgage Note. (Section 3.08)
 
    The Servicer is obligated under the Pooling and Servicing Agreement for each
Series  to realize upon  defaulted Mortgage Loans in  accordance with its normal
servicing practices, which will conform  generally to those of prudent  mortgage
lending  institutions which service mortgage loans of  the same type in the same
jurisdictions. Notwithstanding the foregoing,  the Servicer is authorized  under
the  Pooling and  Servicing Agreement  to permit  the assumption  of a defaulted
Mortgage Loan rather than to foreclose  or accept a deed-in-lieu of  foreclosure
if,  in the  Servicer's judgment, the  default is  unlikely to be  cured and the
assuming borrower meets PHMC's underwriting  guidelines. In connection with  any
such assumption, the Mortgage Interest Rate and the payment terms of the related
Mortgage  Note  will  not  be changed.  See  also  "The  Trust Estates--Mortgage
Loans--Optional Repurchases,"  above,  with respect  to  the Seller's  right  to
repurchase  defaulted Mortgage  Loans. Further,  the Servicer  may encourage the
refinancing of  such defaulted  Mortgage Loans,  including Mortgage  Loans  that
would  permit creditworthy borrowers to  assume the outstanding indebtedness. In
the case of foreclosure or of damage  to a Mortgaged Property from an  uninsured
cause,  the Servicer  is not required  to expend  its own funds  to foreclose or
restore any  damaged property,  unless it  reasonably determines  (i) that  such
foreclosure  or restoration will increase  the proceeds to Certificateholders of
such Series  of liquidation  of the  Mortgage Loan  after reimbursement  of  the
Servicer  for its expenses and (ii) that such expenses will be recoverable to it
through Liquidation Proceeds. In  the event that the  Servicer has expended  its
own funds for foreclosure or to restore damaged property, it will be entitled to
charge  the Certificate Account for such Series an amount equal to all costs and
expenses incurred by it. (Sections 3.03 and 3.09).
 
    The Servicer is not obligated to  foreclose on any Mortgaged Property  which
it  believes  may  be  contaminated  with or  affected  by  hazardous  wastes or
hazardous   substances.   See   "Certain   Legal   Aspects   of   the   Mortgage
Loans--Environmental  Considerations." If the  Servicer does not  foreclose on a
Mortgaged Property, the Certificateholders of the related Series may  experience
a  loss on  the related Mortgage  Loan. The Servicer  will not be  liable to the
Certificateholders if it  fails to foreclose  on a Mortgaged  Property which  it
believes may be so contaminated or affected, even if such Mortgaged Property is,
in  fact, not so contaminated or affected.  Conversely, the Servicer will not be
liable  to  the  Certificateholders  if,  based  on  its  belief  that  no  such
contamination  or effect exists, the Servicer forecloses on a Mortgaged Property
and takes  title  to such  Mortgaged  Property, and  thereafter  such  Mortgaged
Property is determined to be so contaminated or affected.
 
    The  Servicer may foreclose  against property securing  a defaulted Mortgage
Loan either by foreclosure, by sale or by strict foreclosure and in the event  a
deficiency  judgment is  available against  the mortgagor  or other  person (see
"Certain Legal Aspects  of the Mortgage  Loans--Anti-Deficiency Legislation  and
Other
 
                                       54
<PAGE>
Limitations  on  Lenders" for  a discussion  of  the availability  of deficiency
judgments), may proceed for the deficiency. It is anticipated that in most cases
the Servicer  will  not seek  deficiency  judgments,  and the  Servicer  is  not
required under the Pooling and Servicing Agreement to seek deficiency judgments.
 
    With  respect to a Trust Estate (or  a segregated pool of assets therein) as
to which a REMIC election  has been made, if  the trustee acquires ownership  of
any  Mortgaged Property  as a  result of  a default  or imminent  default of any
Mortgage Loan secured by such Mortgaged  Property, the Trustee will be  required
to  dispose of such property  within two years following  its acquisition by the
Trust Estate. The  Servicer also will  be required to  administer the  Mortgaged
Property  in a  manner which does  not cause  the Mortgaged Property  to fail to
qualify as "foreclosure property" within the meaning of Code Section  860G(a)(8)
or result in the receipt by the Trust Estate of any "net income from foreclosure
property"  within  the  meaning  of Code  Section  860G(c)(2),  respectively. In
general, this would preclude  the holding of the  Mortgaged Property by a  party
acting as a dealer in such property or the receipt of rental income based on the
profits  of  the  lessee  of  such property.  See  "Certain  Federal  Income Tax
Consequences."
 
FIXED RETAINED YIELD, SERVICING COMPENSATION AND PAYMENT OF EXPENSES
 
    Fixed Retained Yield with respect to  any Mortgage Loan is that portion,  if
any,  of interest  at the  Mortgage Interest  Rate that  is not  included in the
related Trust  Estate.  The Prospectus  Supplement  for a  Series  will  specify
whether  there is any Fixed Retained Yield with respect to the Mortgage Loans of
such Series.  If  so,  the  Fixed  Retained  Yield  will  be  established  on  a
loan-by-loan  basis  and will  be specified  in the  schedule of  Mortgage Loans
attached as an exhibit  to the applicable Pooling  and Servicing Agreement.  The
Servicer may deduct the Fixed Retained Yield from mortgagor payments as received
and prior to deposit of such payments in the Certificate Account for such Series
or  may  (unless an  election has  been made  to  treat the  Trust Estate  (or a
segregated pool of assets therein) as a REMIC) withdraw the Fixed Retained Yield
from the Certificate Account after the entire payment has been deposited in  the
Certificate  Account. Notwithstanding the foregoing, with respect to any payment
of interest received by the Servicer  relating to a Mortgage Loan (whether  paid
by  the mortgagor  or received  as Liquidation  Proceeds, insurance  proceeds or
otherwise) which is less than the full amount of interest then due with  respect
to  such Mortgage Loan,  the owner of  the Fixed Retained  Yield with respect to
such Mortgage Loan will receive  as its Fixed Retained  Yield only its pro  rata
share of such interest payment.
 
    For  each Series of Certificates,  the Servicer will be  entitled to be paid
the Servicing  Fee  on the  related  Mortgage  Loans until  termination  of  the
applicable  Pooling and Servicing Agreement, subject, unless otherwise specified
in the  applicable  Prospectus  Supplement, to  adjustment  as  described  under
"Adjustment  to Servicing Fee in Connection with Prepaid and Liquidated Mortgage
Loans." The Servicer, at its election, will  pay itself the Servicing Fee for  a
Series  with respect to each Mortgage Loan  by (a) withholding the Servicing Fee
from any scheduled payment of interest prior  to deposit of such payment in  the
Certificate  Account for such  Series or (b) withdrawing  the Servicing Fee from
the Certificate Account after the entire interest payment has been deposited  in
the Certificate Account. The Servicer may also pay itself out of the Liquidation
Proceeds  of  a  Mortgage Loan  or  other  recoveries with  respect  thereto, or
withdraw from the Certificate Account, or if such Liquidation Proceeds or  other
recoveries  are insufficient, from  Net Foreclosure Profits  with respect to the
related Distribution Date the Servicing Fee in respect of such Mortgage Loan  to
the  extent  provided in  the applicable  Pooling  and Servicing  Agreement. The
Servicing Fee with respect to the Mortgage Loans underlying the Certificates  of
a  Series will be specified in  the applicable Prospectus Supplement. Additional
servicing compensation in the form of prepayment charges, assumption fees,  late
payment charges or otherwise will be retained by the Servicer.
 
    The Servicer will pay all expenses incurred in connection with the servicing
of  the  Mortgage  Loans  underlying a  Series,  including,  without limitation,
payment of  the hazard  insurance  policy premiums  and  fees or  other  amounts
payable  pursuant  to  any  applicable agreement  for  the  provision  of credit
enhancement for  such Series,  payment  of the  fees  and disbursements  of  the
Trustee  and any custodian, fees due to the independent accountants and expenses
incurred in  connection with  distributions and  reports to  Certificateholders.
Certain  of these expenses may  be reimbursable to the  Servicer pursuant to the
terms of the applicable Pooling and Servicing Agreement.
 
                                       55
<PAGE>
    As set forth in  the preceding paragraph, the  Servicer will be entitled  to
reimbursement  for  certain  expenses  incurred by  it  in  connection  with the
liquidation of defaulted Mortgage Loans. In the event that claims are either not
made or are not fully paid from  any applicable form of credit enhancement,  the
related Trust Estate will suffer a loss to the extent that Liquidation Proceeds,
after  reimbursement of the Servicing Fee and  the expenses of the Servicer, are
less than the principal  balance of the related  Mortgage Loan. The Servicer  is
also  entitled  to  reimbursement  from  the  Certificate  Account  of  Periodic
Advances, of advances made  by it to pay  taxes, insurance premiums and  similar
items  with respect to any Mortgaged Property, of expenditures incurred by it in
connection with the restoration of any Mortgaged Property and of certain  losses
against which it is indemnified by the Trust Estate. (Section 3.03).
 
EVIDENCE AS TO COMPLIANCE
 
    The  Servicer will deliver  to the Trustee  annually, on or  before the date
specified in  the  Pooling and  Servicing  Agreement, an  Officer's  Certificate
stating that (i) a review of the activities of the Servicer during the preceding
calendar  year and of performance under  the Pooling and Servicing Agreement has
been made under the supervision  of such officer, and (ii)  to the best of  such
officer's  knowledge, based on  such review, the Servicer  has fulfilled all its
obligations under the Pooling and Servicing Agreement throughout such year,  or,
if  there  has  been  a  default in  the  fulfillment  of  any  such obligation,
specifying each such  default known to  such officer and  the nature and  status
thereof.  Such Officer's  Certificate shall be  accompanied by a  statement of a
firm of independent public accountants  to the effect that,  on the basis of  an
examination  of certain  documents and  records relating  to the  mortgage loans
being serviced by the Servicer,  conducted substantially in compliance with  the
Uniform  Single  Audit  Program  for Mortgage  Bankers,  the  servicing  of such
mortgage loans was conducted  in compliance with the  provisions of the  Pooling
and  Servicing  Agreement  and other  similar  agreements, except  for  (i) such
exceptions as such firm believes to be immaterial and (ii) such other exceptions
as are set forth in such statement. (Sections 3.13, 3.14).
 
CERTAIN MATTERS REGARDING THE SERVICER
 
    The Servicer  may not  resign  from its  obligations  and duties  under  the
Pooling  and  Servicing Agreement  for  each Series  (other  than its  duties as
Certificate Registrar for such Series, if it is acting as such), except upon its
determination that  its  duties  thereunder  are  no  longer  permissible  under
applicable  law or are in material conflict by reason of applicable law with any
other activities of a type and nature carried on by it. No such resignation will
become effective until the Trustee for  such Series or a successor servicer  has
assumed  the Servicer's obligations  and duties under  the Pooling and Servicing
Agreement. (Section 6.04).  If the  Servicer resigns  for any  of the  foregoing
reasons  and the  Trustee is  unable or  unwilling to  assume responsibility for
servicing the Mortgage  Loans, it  may appoint another  institution as  mortgage
loan servicer, as described under "Rights Upon Event of Default" below.
 
    The  Pooling  and Servicing  Agreement will  also  provide that  neither the
Servicer, any subservicer, nor any partner, director, officer, employee or agent
of either  of them  (or of  any  partner of  the Servicer),  will be  under  any
liability  to the Trust Estate or the  Certificateholders, for the taking of any
action or for refraining from the taking of any action in good faith pursuant to
the Pooling  and  Servicing Agreement,  or  for errors  in  judgment;  provided,
however, that neither the Servicer, any subservicer, nor any such person will be
protected  against any  liability that would  otherwise be imposed  by reason of
willful misfeasance, bad faith or gross negligence in the performance of his  or
its  duties or  by reason of  reckless disregard  of his or  its obligations and
duties thereunder. The Pooling and Servicing Agreement will further provide that
the Servicer, any subservicer, and  any partner, director, officer, employee  or
agent of either of them (or of any partner of the Servicer) shall be entitled to
indemnification  by the Trust Estate and will be held harmless against any loss,
liability or expense incurred  in connection with any  legal action relating  to
the  Pooling and Servicing  Agreement or the Certificates,  other than any loss,
liability or expense  incurred by reason  of willful misfeasance,  bad faith  or
gross negligence in the performance of his or its duties thereunder or by reason
of  reckless  disregard of  his  or its  obligations  and duties  thereunder. In
addition, the Pooling  and Servicing  Agreement will provide  that the  Servicer
will  not be under  any obligation to  appear in, prosecute  or defend any legal
action that is  not incidental  to its duties  under the  Pooling and  Servicing
Agreement  and that in its  opinion may involve it  in any expense or liability.
The   Servicer    may,   however,    in    its   discretion,    undertake    any
 
                                       56
<PAGE>
such  action deemed by it necessary or desirable with respect to the Pooling and
Servicing 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  Estate and the  Servicer will be
entitled to be reimbursed therefor out of the Certificate Account, and any  loss
to  the Trust Estate arising from such  right of reimbursement will be allocated
pro rata among the various Classes of Certificates unless otherwise specified in
the applicable Pooling and Servicing Agreement. (Section 6.03).
 
    Any person into  which the Servicer  may be merged  or consolidated, or  any
person  resulting  from any  merger, conversion  or  consolidation to  which the
Servicer is  a party,  or any  person  succeeding to  the business  through  the
transfer  of substantially all of its assets, or otherwise, of the Servicer will
be the successor of the Servicer  under the Pooling and Servicing Agreement  for
each  Series provided  that such successor  or resulting entity  is qualified to
service mortgage loans for FNMA  or FHLMC and has a  net worth of not less  than
$15,000,000.
 
    The Servicer also has the right to assign its rights and delegate its duties
and  obligations  under the  Pooling and  Servicing  Agreement for  each Series;
provided that  (i) the  purchaser  or transferee  accepting such  assignment  or
delegation  is  qualified  to  service  mortgage loans  for  FNMA  or  FHLMC, is
satisfactory to the Trustee for such  Series, in the exercise of its  reasonable
judgment,  and executes and  delivers to the  Trustee an agreement,  in form and
substance reasonably satisfactory to the  Trustee, which contains an  assumption
by  such  purchaser  or  transferee  of the  due  and  punctual  performance and
observance of each  covenant and condition  to be performed  or observed by  the
Servicer  under the Pooling and  Servicing Agreement from and  after the date of
such  agreement;  and  (ii)  each  applicable  Rating  Agency's  rating  of  any
Certificates  for such  Series in effect  immediately prior  to such assignment,
sale or  transfer  is not  reasonably  likely  to be  qualified,  downgraded  or
withdrawn  as a result of such assignment, sale or transfer and the Certificates
are not reasonably  likely to  be placed  on credit  review status  by any  such
Rating  Agency. The  Servicer will  be released  from its  obligations under the
Pooling and Servicing Agreement upon any such assignment and delegation,  except
that  the  Servicer  will  remain liable  for  all  liabilities  and obligations
incurred by it prior to  the time that the  conditions contained in clauses  (i)
and (ii) above are met. (Section 6.02).
 
                      THE POOLING AND SERVICING AGREEMENT
 
EVENTS OF DEFAULT
 
    Events  of Default under the Pooling and Servicing Agreement for each Series
include (i) any failure by the Servicer to distribute to Certificateholders  any
required  payment which  continues unremedied  for 10  days after  the giving of
written notice of such failure to the  Servicer by the Trustee for such  Series,
or to the Servicer and the Trustee by the holders of Certificates of such Series
having  voting  rights  allocated  to  such  Certificates  ("Voting  Interests")
aggregating not  less  than  25%  of  the  Voting  Interests  allocated  to  all
Certificates  for such Series; (ii) any failure  by the Servicer duly to observe
or perform in any material respect any  other of its covenants or agreements  in
the  Pooling and Servicing Agreement which  continues unremedied for 60 days (or
30 days in the case of a failure to maintain any pool insurance policy  required
to  be maintained  pursuant to  the Pooling  and Servicing  Agreement) after the
giving of written notice of such failure  to the Servicer by the Trustee, or  to
the  Servicer and  Trustee by the  holders of Certificates  aggregating not less
than  25%  of  the  Voting  Interests;  (iii)  certain  events  in   insolvency,
readjustment   of  debt,  marshalling  of  assets  and  liabilities  or  similar
proceedings and  certain  action  by the  Servicer  indicating  its  insolvency,
reorganization  or inability to  pay its obligations and  (iv) both the Servicer
and any subservicer  appointed by it  to become ineligible  to service for  both
FNMA and FHLMC (unless remedied within 90 days). (Section 7.01).
 
RIGHTS UPON EVENT OF DEFAULT
 
    So  long as  an Event  of Default remains  unremedied under  the Pooling and
Servicing Agreement for  a Series,  the Trustee for  such Series  or holders  of
Certificates of such Series evidencing not less than 25% of the Voting Interests
in  the  Trust  Estate for  such  Series may  terminate  all of  the  rights and
obligations of the
 
                                       57
<PAGE>
Servicer under the Pooling  and Servicing Agreement and  in and to the  Mortgage
Loans  (other than the Servicer's  right to recovery of  any Initial Deposit for
such Series, the aggregate Servicing Fees due prior to the date of  termination,
and other expenses and amounts advanced pursuant to the terms of the Pooling and
Servicing   Agreement,  which  rights   the  Servicer  will   retain  under  all
circumstances), whereupon the Trustee will succeed to all the  responsibilities,
duties and liabilities of the Servicer under the Pooling and Servicing Agreement
and  will  be  entitled to  monthly  servicing  compensation not  to  exceed the
aggregate Servicing Fees together with  the other servicing compensation in  the
form  of assumption fees, late  payment charges or otherwise  as provided in the
Pooling and Servicing Agreement. In the  event that the Trustee is unwilling  or
unable  so to act, it may select, pursuant to the public bid procedure described
in the  applicable Pooling  and  Servicing Agreement,  or  petition a  court  of
competent  jurisdiction to appoint, a housing and home finance institution, bank
or mortgage servicing institution  with a net worth  of at least $10,000,000  to
act  as  successor to  the  Servicer under  the  provisions of  the  Pooling and
Servicing Agreement relating  to the  servicing of  the Mortgage  Loans. In  the
event  such public  bid procedure is  utilized, the successor  servicer would be
entitled to servicing compensation in an amount equal to the aggregate Servicing
Fees, together with the other servicing  compensation in the form of  assumption
fees,  late  payment  charges  or  otherwise, as  provided  in  the  Pooling and
Servicing Agreement,  and the  Servicer would  be entitled  to receive  the  net
profits,  if any, realized from the sale of its servicing rights and obligations
under the Pooling and Servicing Agreement. (Sections 7.01 and 7.05).
 
    During the  continuance  of any  Event  of  Default under  the  Pooling  and
Servicing  Agreement for  a Series,  the Trustee for  such Series  will have the
right to take  action to  enforce its  rights and  remedies and  to protect  and
enforce  the rights and  remedies of the Certificateholders  of such Series, and
holders of Certificates evidencing not less than 25% of the Voting Interests for
such Series may direct the time,  method and place of conducting any  proceeding
for  any  remedy available  to  the Trustee  or  exercising any  trust  or power
conferred upon  the  Trustee.  However,  the  Trustee  will  not  be  under  any
obligation to pursue any such remedy or to exercise any of such trusts or powers
unless  such Certificateholders have offered  the Trustee reasonable security or
indemnity against the cost,  expenses and liabilities which  may be incurred  by
the  Trustee thereby. Also, the Trustee may decline to follow any such direction
if the Trustee  determines that  the action or  proceeding so  directed may  not
lawfully  be taken  or would  involve it  in personal  liability or  be unjustly
prejudicial to the non-assenting Certificateholders. (Sections 7.02 and 7.03).
 
    No Certificateholder of a Series, solely  by virtue of such holder's  status
as  a Certificateholder,  will have  any right  under the  Pooling and Servicing
Agreement for  such Series  to  institute any  proceeding  with respect  to  the
Pooling  and Servicing Agreement, unless such holder previously has given to the
Trustee for such  Series written  notice of default  and unless  the holders  of
Certificates  evidencing  not less  than 25%  of the  Voting Interests  for such
Series 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. (Section 10.03).
 
AMENDMENT
 
    Each Pooling  and Servicing  Agreement may  be amended  by the  Seller,  the
Servicer  and the Trustee without the  consent of the Certificateholders, (i) to
cure any ambiguity, (ii) to correct or supplement any provision therein that may
be inconsistent with any other provision therein, (iii) to modify, eliminate  or
add  to any of its  provisions to such extent as  shall be necessary to maintain
the qualification of the Trust Estate  (or a segregated pool of assets  therein)
as  a REMIC at  all times that any  Certificates are outstanding  or to avoid or
minimize the risk of the imposition of  any tax on the Trust Estate pursuant  to
the  Code that  would be  a claim  against the  Trust Estate,  provided that the
Trustee has received an  opinion of counsel  to the effect  that such action  is
necessary  or desirable to  maintain such qualification or  to avoid or minimize
the risk  of the  imposition  of any  such  tax and  such  action will  not,  as
evidenced  by such opinion of counsel,  adversely affect in any material respect
the interests of any Certificateholder, (iv) to change the timing and/or  nature
of deposits into the Certificate Account, provided that such change will not, as
evidenced by an opinion of counsel, adversely affect in any material respect the
interests  of  any Certificateholder  and that  such  change will  not adversely

letter from
 
                                       58
<PAGE>
each  Rating  Agency to  such effect,  (v) to  add to,  modify or  eliminate any
provisions therein  restricting transfers  of residual  Certificates to  certain
disqualified  organizations described  below under  "Certain Federal  Income Tax
Consequences--Federal Income Tax  Consequences for REMIC  Certificates--Taxation
of  Residual  Certificates--Tax-Related  Restrictions  on  Transfer  of Residual
Certificates," or (vi) to make any  other provisions with respect to matters  or
questions  arising  under  such Pooling  and  Servicing Agreement  that  are not
inconsistent with the provisions thereof, provided that such action will not, as
evidenced by an opinion of counsel, adversely affect in any material respect the
interests of  the Certificateholders  of  the related  Series. The  Pooling  and
Servicing  Agreement may  also be  amended by the  Seller, the  Servicer and the
Trustee with the  consent of  the holders of  Certificates evidencing  interests
aggregating  not less  than 66  2/3% of  the Voting  Interests evidenced  by the
Certificates of each  Class or  Subclass affected  thereby, for  the purpose  of
adding  any provisions to  or changing in  any manner or  eliminating any of the
provisions of such Pooling and Servicing Agreement or of modifying in any manner
the rights of the Certificateholders; provided, however, that no such  amendment
may (i) reduce in any manner the amount of, or delay the timing of, any payments
received  on  or  with  respect  to  Mortgage  Loans  that  are  required  to be
distributed on  any Certificates,  without the  consent of  the holder  of  such
Certificate,  (ii) adversely affect in any material respect the interests of the
holders of a Class  or Subclass of  Certificates of a Series  in a manner  other
than  that  set  forth  in (i)  above  without  the consent  of  the  holders of
Certificates aggregating not less than 66 2/3% of the Voting Interests evidenced
by such  Class  or  Subclass,  or  (iii)  reduce  the  aforesaid  percentage  of
Certificates  of any  Class or  Subclass, the holders  of which  are required to
consent  to  such  amendment,  without  the  consent  of  the  holders  of   all
Certificates   of   such   Class   or   Subclass   affected   then  outstanding.
Notwithstanding the  foregoing,  the  Trustee  will  not  consent  to  any  such
amendment if such amendment would subject the Trust Estate (or a segregated pool
of  assets therein)  to tax  or cause  the Trust  Estate (or  segregated pool of
assets therein) to fail to qualify as a REMIC.
 
TERMINATION; PURCHASE OF MORTGAGE LOANS
 
    The obligations created by the Pooling and Servicing Agreement for a  Series
of  Certificates will  terminate on  the Distribution  Date following  the final
payment or other liquidation of the  last Mortgage Loan subject thereto and  the
disposition of all property acquired upon foreclosure of any such Mortgage Loan.
In  no  event, however,  will the  trust  created by  the Pooling  and Servicing
Agreement continue beyond the expiration of 21 years from the death of the  last
survivor  of certain persons named in  such Pooling and Servicing Agreement. For
each Series of Certificates, the Trustee will give written notice of termination
of the Pooling and Servicing Agreement to each Certificateholder, and the  final
distribution   will  be  made  only  upon  surrender  and  cancellation  of  the
Certificates at an office or agency appointed by the Seller and specified in the
notice of termination.
 
    If so  provided  in  the  related Prospectus  Supplement,  the  Pooling  and
Servicing  Agreement  for  each  Series of  Certificates  will  permit,  but not
require, the  person  or persons  specified  in such  Prospectus  Supplement  to
purchase  from the Trust Estate for such  Series all remaining Mortgage Loans at
the time subject to the Pooling and Servicing Agreement at a price specified  in
such  Prospectus  Supplement. In  the  event that  the  Servicer has  caused the
related Trust Estate (or a segregated pool of assets therein) to be treated as a
REMIC, any  such  purchase  will  be effected  only  pursuant  to  a  "qualified
liquidation"  as defined  in Code Section  860F(a)(4)(A) and the  receipt by the
Trustee of an opinion of counsel that  such purchase will not (i) result in  the
imposition  of a tax on "prohibited transactions" under Code Section 860F(a)(1),
(ii) otherwise subject the REMIC to tax,  or (iii) cause the Trust Estate (or  a
segregated  pool of assets) to fail to qualify  as a REMIC. The exercise of such
right will effect early retirement of  the Certificates of that Series, but  the
right so to purchase may be exercised only after the aggregate principal balance
of  the Mortgage Loans  for such Series at  the time of purchase  is less than a
specified percentage of the aggregate principal balance at the Cut-Off Date  for
the Series, or after the date set forth in the related Prospectus Supplement.
 
THE TRUSTEE
 
    The  Trustee under each Pooling and Servicing Agreement (the "Trustee") will
be named in the applicable Prospectus  Supplement. The commercial bank or  trust
company serving as Trustee may have normal banking relationships with the Seller
or any of its affiliates.
 
                                       59
<PAGE>
    The  Trustee may  resign at any  time, in  which event the  Servicer will be
obligated to  appoint a  successor trustee.  The Servicer  may also  remove  the
Trustee if the Trustee ceases to be eligible to act as Trustee under the Pooling
and  Servicing Agreement, if the Trustee becomes insolvent or in order to change
the situs of the Trust Estate for state tax reasons. Upon becoming aware of such
circumstances, the  Servicer  will  become  obligated  to  appoint  a  successor
trustee.  The  Trustee  may  also be  removed  at  any time  by  the  holders of
Certificates evidencing not less than 51%  of the Voting Interests in the  Trust
Estate,  except that, any Certificate registered in  the name of the Seller, the
Servicer or any affiliate thereof will not be taken into account in  determining
whether  the requisite Voting  Interest in the Trust  Estate necessary to effect
any such removal has been obtained. Any resignation and removal of the  Trustee,
and  the appointment  of a  successor trustee,  will not  become effective until
acceptance of such appointment  by the successor trustee.  The Trustee, and  any
successor  trustee,  will  have  a  combined capital  and  surplus  of  at least
$50,000,000, or  will  be a  member  of a  bank  holding system,  the  aggregate
combined capital and surplus of which is at least $50,000,000, provided that the
Trustee's and any such successor trustee's separate capital and surplus shall at
all  times be at  least the amount  specified in Section  310(a)(2) of the Trust
Indenture Act of  1939, and  will be subject  to supervision  or examination  by
federal or state authorities.
 
                  CERTAIN LEGAL ASPECTS OF THE MORTGAGE LOANS
 
    The  following  discussion contains  summaries of  certain legal  aspects of
mortgage loans  which are  general in  nature. Because  such legal  aspects  are
governed  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, nor to encompass  the laws of  all states in which  the security for  the
Mortgage  Loans is  situated. The summaries  are qualified in  their entirety by
reference to the applicable federal and state laws governing the Mortgage Loans.
 
GENERAL
 
    The Mortgage Loans will, in general, be secured by either first mortgages or
first deeds of  trust, depending upon  the prevailing practice  in the state  in
which  the underlying property  is located. A  mortgage creates a  lien upon the
real property described in  the mortgage. There are  two parties to a  mortgage:
the  mortgagor, who is the borrower; and the  mortgagee, who is the lender. In a
mortgage state instrument,  the mortgagor delivers  to the mortgagee  a note  or
bond  evidencing the loan and the mortgage.  Although a deed of trust is similar
to a mortgage, a deed of trust has three parties: a borrower called the  trustor
(similar  to  a  mortgagor),  a  lender called  the  beneficiary  (similar  to a
mortgagee), and a third-party grantee called the trustee. Under a deed of trust,
the borrower grants the property, irrevocably until the debt is paid, in  trust,
generally  with a power of  sale, to the trustee to  secure payment of the loan.
The trustee's authority  under a  deed of  trust and  the mortgagee's  authority
under  a mortgage are governed by the express provisions of the deed of trust or
mortgage, applicable law, and, in some cases, with respect to the deed of trust,
the directions of the beneficiary.
 
FORECLOSURE
 
    Foreclosure of  a mortgage  is generally  accomplished by  judicial  action.
Generally,  the action is initiated  by the service of  legal pleadings upon all
parties having an interest of record in the real property. Delays in  completion
of  the  foreclosure  occasionally  may  result  from  difficulties  in locating
necessary parties  defendant.  When  the mortgagee's  right  of  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  may  issue a  judgment of  foreclosure  and appoint  a receiver  or other
officer to conduct the sale of the property. In some states, mortgages may  also
be  foreclosed by  advertisement, pursuant  to a power  of sale  provided in the
mortgage. Foreclosure of a mortgage  by advertisement is essentially similar  to
foreclosure of a deed of trust by non-judicial power of sale.
 
    Foreclosure  of a deed of trust  is generally accomplished by a non-judicial
trustee's sale under a specific provision  in the deed of trust that  authorizes
the  trustee to  sell the  property to  a third  party upon  any default  by the
borrower under the terms of the note  or deed of trust. In certain states,  such
foreclosure also
 
                                       60
<PAGE>
may be accomplished by judicial action in the manner provided for foreclosure of
mortgages.  In some states, 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 a notice of default and notice of sale. In addition, the trustee must
provide notice in  some states  to any other  individual having  an interest  of
record  in the real property,  including any junior lienholders.  If the deed of
trust is not reinstated within any applicable cure period, a notice of sale must
be posted in  a public  place and,  in most  states, published  for a  specified
period  of time in one or more  newspapers. In addition, some state laws require
that a copy of  the notice of  sale be posted  on the property  and sent to  all
parties having an interest of record in the property.
 
    In  some states, 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 attorneys' fees, which may be recovered by a lender.
 
    In  case of foreclosure under either a mortgage or a deed of trust, the sale
by the receiver  or other designated  officer, or  by the trustee,  is a  public
sale.  However, because of  the difficulty a  potential buyer at  the sale would
have in determining the exact status of title and because the physical condition
of the property may have deteriorated during the foreclosure proceedings, it  is
uncommon  for a third  party to purchase  the property at  the foreclosure sale.
Rather, it is common for the lender to purchase the property from the trustee or
receiver for an amount equal to the unpaid principal amount of the note, accrued
and unpaid interest and the expenses of foreclosure. Thereafter, subject to  the
right  of  the  borrower in  some  states  to remain  in  possession  during the
redemption period, the lender  will assume the  burdens 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 commonly  will
obtain  the services of a real estate broker  and pay the broker a commission in
connection with the sale of the property. Depending upon market conditions,  the
ultimate  proceeds  of the  sale  of the  property  may not  equal  the lender's
investment in the property. Any loss may  be reduced by the receipt of  mortgage
insurance  proceeds, if any, or by judicial  action against the borrower for the
deficiency,  if  such  action  is  permitted  by  law.  See   "--Anti-Deficiency
Legislation and Other Limitations on Lenders" below.
 
FORECLOSURE ON SHARES OF COOPERATIVES
 
    The  cooperative shares owned  by the tenant-stockholder  and pledged to the
lender are, in  almost all  cases, subject to  restrictions on  transfer as  set
forth  in the cooperative's Certificate of Incorporation and By-laws, as well as
in the proprietary  lease or occupancy  agreement, and may  be cancelled by  the
cooperative  for  failure  by  the  tenant-stockholder  to  pay  rent  or  other
obligations or  charges owed  by such  tenant-stockholder, including  mechanics'
liens  against  the  cooperative  apartment building  incurred  by  such tenant-
stockholder. The proprietary lease or occupancy agreement generally permits  the
cooperative  to terminate such lease or agreement  in the event an obligor fails
to  make  payments  or  defaults  in  the  performance  of  covenants   required
thereunder.  Typically, the lender and the  cooperative enter into a recognition
agreement which establishes the  rights and obligations of  both parties in  the
event  of  a default  by  the tenant-stockholder  on  its obligations  under the
proprietary lease or  occupancy agreement. A  default by the  tenant-stockholder
under  the proprietary  lease or occupancy  agreement will  usually constitute a
default  under   the   security   agreement   between   the   lender   and   the
tenant-stockholder.
 
    The  recognition agreement  generally provides that,  in the  event that the
tenant-stockholder has  defaulted  under  the  proprietary  lease  or  occupancy
agreement,  the  cooperative will  take  no action  to  terminate such  lease or
agreement until the lender has been provided an opportunity to cure the default.
The recognition agreement typically  provides that if  the proprietary lease  or
occupancy  agreement is terminated, the  cooperative will recognize the lender's
lien against  proceeds  from  a  sale of  the  cooperative  apartment,  subject,
however,  to the cooperative's right to sums due under such proprietary lease or
occupancy
 
                                       61
<PAGE>
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  by the  agreement  in any  rights it  may  have to  dispossess the
tenant-stockholders.
 
    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 corporation to receive sums due under
the proprietary lease or occupancy  agreement. If there are proceeds  remaining,
the  lender must account to the  tenant-stockholder for the surplus. Conversely,
if a  portion of  the  indebtedness remains  unpaid, the  tenant-stockholder  is
generally  responsible for the deficiency.  See "Anti-Deficiency Legislation and
Other Limitations on Lenders" below.
 
RIGHTS OF REDEMPTION
 
    In some states, after sale pursuant to a deed of trust and/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
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 delay  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 maintain  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, 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  former
borrower  equal in most  cases to the  difference between the  amount due to the
lender and the net amount realized upon the foreclosure sale.
 
    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.
 
                                       62
<PAGE>
    Other  statutory provisions  may limit  any deficiency  judgment against the
former borrower following a  foreclosure sale to the  excess of the  outstanding
debt  over the fair market value  of the property at the  time of such sale. The
purpose of  these statutes  is to  prevent  a beneficiary  or a  mortgagee  from
obtaining a large deficiency judgment against the former borrower as a result of
low or no bids at the foreclosure sale.
 
    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.
 
    Generally, Article 9 of  the UCC governs  foreclosure on cooperative  shares
and  the related proprietary lease or occupancy agreement and foreclosure on the
beneficial interest in a land trust. Some courts have interpreted Section  9-504
of  the UCC to prohibit a deficiency  award unless the creditor establishes that
the sale of the  collateral (which, in  the case of a  Mortgage Loan secured  by
shares  of a cooperative, would be such shares and the related proprietary lease
or occupancy agreement) was conducted in a commercially reasonable manner.
 
    The Servicer is not  required under the Pooling  and Servicing Agreement  to
pursue deficiency judgments on the Mortgage Loans even if permitted by law.
 
    In  addition  to  anti-deficiency and  related  legislation,  numerous other
federal and state  statutory provisions, including  the federal bankruptcy  laws
and  state laws affording  relief to debtors,  may interfere with  or affect the
ability of a secured mortgage lender to realize upon its security. For  example,
in  a Chapter  13 proceeding  under the  federal Bankruptcy  Code, when  a court
determines that the value of  a home is less than  the principal balance of  the
loan,  the court may prevent a lender from foreclosing on the home, and, as part
of the rehabilitation plan, reduce the amount of the secured indebtedness to the
value of the home as it exists at the time of the proceeding, leaving the lender
as a general unsecured  creditor for the difference  between that value and  the
amount  of outstanding indebtedness.  A bankruptcy court may  grant the debtor a
reasonable time to cure a  payment default, and in the  case of a mortgage  loan
not  secured by  the debtor's principal  residence, also may  reduce the monthly
payments due under such mortgage loan,  change the rate of interest, reduce  the
principal balance of the loan to the then-current appraised value of the related
Mortgaged Property and alter the mortgage loan repayment schedule. Certain court
decisions  have applied such relief to  claims secured by the debtor's principal
residence. If  a  court  relieves  a  borrower's  obligation  to  repay  amounts
otherwise  due on a Mortgage Loan, the  Servicer will not be required to advance
such  amounts,  and  any  loss  in   respect  thereof  will  be  borne  by   the
Certificateholders.
 
    The  Internal Revenue Code of 1986, as amended, provides priority to certain
tax liens over  the lien  of the mortgage  or deed  of trust. The  laws of  some
states  provide priority to certain  tax liens over the  lien of the mortgage or
deed of trust. Numerous federal and  some 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 laws  and state  laws  impose
specific  statutory liabilities upon  lenders who originate  or service mortgage
loans and who fail to comply with the provisions of the law. In some cases, this
liability may affect assignees of the mortgage loans.
 
SOLDIERS' AND SAILORS' CIVIL RELIEF ACT AND SIMILAR LAWS
 
    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  action  could  have  an  effect,  for  an
indeterminate  period of time,  on the ability  of the Servicer  to collect full
amounts of interest  on certain of  the Mortgage  Loans in a  Trust Estate.  Any
shortfall  in interest collections resulting from  the application of the Relief
Act could result in  losses to the  holders of the  Certificates of the  related
Series.  Further,  the Relief  Act imposes  limitations  which would  impair the
ability of the  Servicer to foreclose  on an affected  Mortgage Loan during  the
borrower's   period   of  active   duty  status.   Thus,   in  the   event  that
 
                                       63
<PAGE>
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 states have enacted comparable legislation which may  interfere
with  or  affect the  ability  of the  Servicer  to timely  collect  payments of
principal and interest on,  or to foreclose on,  Mortgage Loans of borrowers  in
such states who are active or reserve members of the armed services.
 
ENVIRONMENTAL CONSIDERATIONS
    Under  the  federal  Comprehensive Environmental  Response  Compensation and
Liability Act, as  amended, and  under state law  in certain  states, a  secured
party  which takes a deed in lieu of foreclosure, purchases a mortgaged property
at a foreclosure  sale or  operates a mortgaged  property may  become liable  in
certain  circumstances for  the costs  of remedial  action ("Cleanup  Costs") if
hazardous wastes or hazardous  substances have been released  or disposed of  on
the  property. Such Cleanup Costs  may be substantial. It  is possible that such
Cleanup Costs  could become  a liability  of  the Trust  Estate and  reduce  the
amounts  otherwise  distributable  to  the  Certificateholders  if  a  Mortgaged
Property securing a  Mortgage Loan became  the property of  the Trust Estate  in
certain circumstances and if such Cleanup Costs were incurred. Moreover, certain
states  by statute impose a lien for any Cleanup Costs incurred by such state on
the property that  is the  subject of such  Cleanup Costs  (a "Superlien").  All
subsequent  liens on  such property are  subordinated to such  Superlien and, in
some states, even prior recorded liens  are subordinated to such Superliens.  In
the  latter states, the security  interest of the Trustee  in a property that is
subject to such a Superlien could be adversely affected.
 
    Traditionally, residential mortgage lenders have not taken steps to evaluate
whether hazardous wastes or hazardous substances are present with respect to any
mortgaged property prior  to the origination  of the mortgage  loan or prior  to
foreclosure or accepting a deed-in-lieu of foreclosure. Accordingly, neither the
Seller  nor  PHMC has  made such  evaluations  prior to  the origination  of the
Mortgage Loans,  nor  does either  require  that  such evaluations  be  made  by
originators  who have sold  the Mortgage Loans  to PHMC. Neither  the Seller nor
PHMC is  required to  undertake any  such evaluations  prior to  foreclosure  or
accepting  a deed-in-lieu of  foreclosure. Neither the  Seller, the Servicer nor
PHMC makes  any representations  or  warranties or  assumes any  liability  with
respect  to the absence or effect of hazardous wastes or hazardous substances on
any Mortgaged Property or any casualty resulting from the presence or effect  of
hazardous  wastes  or  hazardous substances.  See  "The  Trust Estates--Mortgage
Loans--Representations  and   Warranties"  and   "Servicing  of   the   Mortgage
Loans--Enforcement  of Due-on-Sale Clauses;  Realization Upon Defaulted Mortgage
Loans" above.
 
"DUE-ON-SALE" CLAUSES
    The forms  of note,  mortgage and  deed of  trust relating  to  conventional
Mortgage Loans may contain a "due-on-sale" clause permitting acceleration of the
maturity  of a loan if  the borrower transfers its  interest in the property. In
recent  years,  court  decisions  and  legislative  actions  placed  substantial
restrictions  on the right  of lenders to  enforce such clauses  in many states.
However, effective  October  15,  1982, Congress  enacted  the  Garn-St  Germain
Depository  Institutions Act of 1982 (the  "Garn Act") which purports to preempt
state laws which prohibit the enforcement of "due-on-sale" clauses by  providing
among  other matters, that  "due-on-sale" clauses in  certain loans (which loans
may include the Mortgage Loans)  made after the effective  date of the Garn  Act
are enforceable, within certain limitations as set forth in the Garn Act and the
regulations  promulgated thereunder. "Due-on-sale" clauses contained in mortgage
loans originated by  federal savings  and loan associations  or federal  savings
banks  are fully  enforceable pursuant  to regulations  of the  Office of Thrift
Supervision ("OTS"), as successor to the Federal Home Loan Bank Board ("FHLBB"),
which preempt  state  law  restrictions  on the  enforcement  of  such  clauses.
Similarly,  "due-on-sale" clauses in  mortgage loans made  by national banks and
federal  credit  unions  are  now  fully  enforceable  pursuant  to   preemptive
regulations  of the  Comptroller of the  Currency and the  National Credit Union
Administration, respectively.
 
    The  Garn  Act  created  a  limited  exemption  from  its  general  rule  of
enforceability  for  "due-on-sale" clauses  in  certain mortgage  loans ("Window
Period Loans") which were originated by non-federal lenders and made or  assumed
in  certain states ("Window Period States")  during the period, prior to October
15, 1982,  in  which that  state  prohibited the  enforcement  of  "due-on-sale"
clauses by constitutional provision,
 
                                       64

statute  or statewide court  decision (the "Window  Period"). Though neither the
Garn Act nor the  OTS regulations actually names  the Window Period States,  the
Federal  Home Loan Mortgage  Corporation has taken  the position, in prescribing
mortgage loan servicing standards  with respect to mortgage  loans which it  has
purchased,  that the Window  Period States were:  Arizona, Arkansas, California,
Colorado, Georgia, Iowa, Michigan, Minnesota,  New Mexico, Utah and  Washington.
Under  the Garn  Act, unless a  Window Period  State took action  by October 15,
1985, the  end  of  the  Window  Period,  to  further  regulate  enforcement  of
"due-on-sale" clauses in Window Period Loans, "due-on-sale" clauses would become
enforceable  even  in Window  Period  Loans. Five  of  the Window  Period States
(Arizona, Minnesota, Michigan,  New Mexico  and Utah) have  taken actions  which
restrict  the  enforceability of  "due-on-sale" clauses  in Window  Period Loans
beyond October 15, 1985. The actions taken vary among such states.
 
    By virtue  of the  Garn Act,  the  Servicer may  generally be  permitted  to
accelerate  any conventional Mortgage Loan which contains a "due-on-sale" clause
upon transfer of an interest in the property subject to the mortgage or deed  of
trust.  With respect to any Mortgage Loan  secured by a residence occupied or to
be occupied  by the  borrower, this  ability  to accelerate  will not  apply  to
certain  types of transfers, including (i)  the granting of a leasehold interest
which has a term of three years or less and which does not contain an option  to
purchase,  (ii) a transfer to a relative resulting from the death of a borrower,
or a transfer where the  spouse or children become an  owner of the property  in
each  case where  the transferee(s) will  occupy the property,  (iii) a transfer
resulting from a decree of  dissolution of marriage, legal separation  agreement
or  from an incidental property settlement agreement by which the spouse becomes
an owner of  the property,  (iv) the  creation of  a lien  or other  encumbrance
subordinate  to  the lender's  security instrument  which does  not relate  to a
transfer of rights  of occupancy  in the property  (provided that  such lien  or
encumbrance  is not created pursuant to a  contract for deed), (v) a transfer by
devise, descent or operation of law on the death of a joint tenant or tenant  by
the  entirety, and  (vi) other transfers  as set forth  in the Garn  Act and the
regulations thereunder. The extent of the effect of the Garn Act on the  average
lives  and  delinquency rates  of the  Mortgage Loans  cannot be  predicted. See
"Prepayment and Yield Considerations."
 
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 OTS as successor to the
FHLBB  is   authorized  to   issue  rules   and  regulations   and  to   publish
interpretations  governing implementation of Title V. The statute authorized any
state to reimpose interest rate limits by  adopting before April 1, 1983, a  law
or  constitutional provision which expressly  rejects application of the federal
law. Fifteen  states have  adopted laws  reimposing or  reserving the  right  to
reimpose  interest  rate limits.  In  addition, even  where  Title V  is  not so
rejected, any state is  authorized to adopt a  provision limiting certain  other
loan charges.

    The Seller will represent and warrant in the Pooling and Servicing Agreement
to the Trustee for the benefit of Certificateholders that all Mortgage Loans are
originated  in full compliance with applicable state laws, including usury laws.
See "The Pooling and  Servicing Agreement--Assignment of  Mortgage Loans to  the
Trustee."
 
ENFORCEABILITY OF CERTAIN PROVISIONS
 
    Standard  forms  of  note,  mortgage and  deed  of  trust  generally contain
provisions obligating the  borrower to  pay a late  charge if  payments are  not
timely  made  and  in some  circumstances  may  provide for  prepayment  fees or
penalties if the obligation is paid prior to maturity. In certain states,  there
are  or may be specific limitations upon late charges which a lender may collect
from a borrower for delinquent payments.  Certain states also limit the  amounts
that a lender may collect from a borrower as an additional charge if the loan is
prepaid.  Under the Pooling and Servicing Agreement, late charges and prepayment
fees (to the extent  permitted by law  and not waived by  the Servicer) will  be
retained by the Servicer as additional servicing compensation.
 
    Courts  have imposed  general equitable  principles upon  foreclosure. These
equitable principles are  generally designed  to relieve the  borrower from  the
legal effect of defaults under the loan documents. Examples of judicial remedies
that  may be fashioned  include judicial requirements  that the lender undertake
affirmative and expensive  actions to  determine the causes  for the  borrower's
default and the likelihood that the borrower will be able to reinstate the loan.
In  some cases, courts have substituted their judgment for the lender's judgment
and have required  lenders to  reinstate loans  or recast  payment schedules  to
accommodate  borrowers who are suffering from temporary financial disability. In
some cases, courts have limited the right of lenders to foreclose if the default
under the mortgage instrument is not  monetary, such as the borrower failing  to
adequately  maintain the property or the borrower executing a second mortgage or
deed of trust  affecting the  property. In other  cases, some  courts have  been
faced  with  the  issue  whether  federal  or  state  constitutional  provisions
reflecting due process concerns for adequate notice require that borrowers under
the deeds of  trust receive  notices in addition  to the  statutorily-prescribed
minimum  requirements. For  the most  part, these  cases have  upheld the notice
provisions as being reasonable or have found that the sale by a trustee under  a
deed  of trust  or under  a mortgage  having a  power of  sale does  not involve
sufficient state action to afford constitutional protections to the borrower.
 
                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
    The following is a  general discussion of  the anticipated material  federal
income   tax  consequences  of  the  purchase,  ownership,  and  disposition  of
Certificates, which may consist of REMIC Certificates, Standard Certificates  or
Stripped Certificates, as described below. The discussion below does not purport
to  address  all  federal income  tax  consequences  that may  be  applicable to
particular categories of  investors, some  of which  may be  subject to  special
rules.  The authorities on which this discussion  is based are subject to change
or differing interpretations, and any such change or interpretation could  apply
retroactively.  This discussion reflects the enactment  of the Tax Reform Act of
1986 (the "1986 Act")  and the Technical and  Miscellaneous Revenue Act of  1988
("TAMRA"),  as well as  proposed regulations (the  "Proposed REMIC Regulations")
promulgated by  the U.S.  Department  of the  Treasury  on September  27,  1991.
Investors  should be  aware that the  Proposed REMIC Regulations  are subject to
change and  are  not binding  authority  until  adopted as  final  or  temporary
regulations.  However, to the extent adopted  as currently drafted, the Proposed
REMIC Regulations may apply to  the REMIC Certificates retroactively as  binding
authority.  Investors should consult  their own tax  advisors in determining the
federal, state, local, and any other  tax consequences to them of the  purchase,
ownership, and disposition of Certificates, particularly with respect to federal
income  tax  changes effected  by the  1986  Act, TAMRA  and the  Proposed REMIC
Regulations.

    For purposes of this discussion, where the applicable Prospectus  Supplement
provides  for a  Fixed Retained Yield  with respect  to the Mortgage  Loans of a
Series of Certificates, references to the Mortgage Loans will be deemed to refer
to that portion of the  Mortgage Loans held by the  Trust Estate which does  not
include the Fixed Retained Yield.
 
             FEDERAL INCOME TAX CONSEQUENCES FOR REMIC CERTIFICATES
 
GENERAL
 
    With respect to a particular Series of Certificates, an election may be made
to  treat the Trust Estate or one or  more segregated pools of assets therein as
one or more REMICs within the meaning of Code Section 860D. A Trust Estate or  a
portion or portions thereof as to which one or more REMIC elections will be made
will  be  referred  to as  a  "REMIC  Pool." For  purposes  of  this discussion,
Certificates of a Series as to which one or more REMIC elections are made, which
will include all Multi-Class Certificates and may include Standard  Certificates
or  Stripped Certificates or  both, are referred to  as "REMIC Certificates" and
will consist of one or more Classes  of "Regular Certificates" and one Class  of
"Residual Certificates" in the case of each REMIC Pool. Qualification as a REMIC
requires ongoing compliance with certain conditions. With respect to each Series
of REMIC Certificates, Cadwalader, Wickersham & Taft, counsel to the Seller, has
advised  the Seller that  in the firm's  opinion, assuming (i)  the making of an
appropriate election, (ii) compliance with the Pooling and Servicing  Agreement,
and  (iii) compliance with any  changes in the law,  including any amendments to
the Code or  applicable Treasury  regulations thereunder, each  REMIC Pool  will
qualify as a REMIC. In such case, the Regular Certificates will be considered to
be  "regular interests"  in the  REMIC Pool  and generally  will be  treated for
federal income tax purposes as if  they were newly originated debt  instruments,
and  the Residual Certificates will be  considered to be "residual interests" in
the REMIC Pool. The Prospectus Supplement  for each Series of Certificates  will
indicate  whether one or more REMIC elections  with respect to the related Trust
Estate will be made, in which event references to "REMIC" or "REMIC Pool" herein
shall be deemed to refer to each such REMIC Pool.
 
STATUS OF REMIC CERTIFICATES
 
    REMIC Certificates held by a mutual savings bank or a domestic building  and
loan  association will  constitute "qualifying  real property  loans" within the
meaning of Code Section 593(d)(1) in the same proportion that the assets of  the
REMIC  Pool would be so treated. REMIC  Certificates held by a domestic building
and loan association will constitute "a regular or residual interest in a REMIC"
within the meaning  of Code  Section 7701(a)(19)(C)(xi) in  the same  proportion
that  the assets of  the REMIC Pool  would be treated  as "loans...secured by an
interest in real property" within the meaning of Code Section  7701(a)(19)(C)(v)
or  as other assets described in Code Section 7701(a)(19)(C). REMIC Certificates
held by a  real estate  investment trust  will constitute  "real estate  assets"
within  the  meaning of  Code Section  856(c)(5)(A), and  interest on  the REMIC
Certificates will be considered "interest on obligations secured by mortgages on
real property  or on  interests in  real property"  within the  meaning of  Code
Section  856(c)(3)(B) in the same proportion that, for both purposes, the assets
of the REMIC Pool would be so treated. If at all times 95% or more of the assets
of the  REMIC Pool  qualify for  each  of the  foregoing treatments,  the  REMIC
Certificates  will qualify for  the corresponding status  in their entirety. The
Proposed REMIC Regulations provide that, for purposes of Code Sections 593(d)(1)
and 856(c)(5)(A), payments of principal and interest on the Mortgage Loans  that
are reinvested pending distribution to holders of REMIC Certificates qualify for
such treatment. Where two REMIC Pools are a part of a tiered structure they will
be  treated as one  REMIC for purposes  of the tests  described above respecting
asset ownership of  more or less  than 95%. In  addition, if the  assets of  the
REMIC  include Buy-Down Loans, it is possible that the percentage of such assets
constituting "qualifying real property loans" or "loans...secured by an interest
in real property" for purposes of Code Sections 593(d)(1) and 7701(a)(19)(C)(v),
respectively, may  be  required to  be  reduced by  the  amount of  the  related
Buy-Down  Funds. REMIC Certificates held by  a regulated investment company will
not constitute "Government
 
                                       67
<PAGE>
securities"  within  the   meaning  of  Code   Section  851(b)(4)(A)(i).   REMIC
Certificates held by certain financial institutions will constitute an "evidence
of indebtedness" within the meaning of Code Section 582(c)(1).
 
QUALIFICATION AS A REMIC
 
    In  order for the  REMIC Pool to qualify  as a REMIC,  there must be ongoing
compliance on the part of the REMIC Pool with the requirements set forth in  the
Code.  The REMIC Pool  must fulfill an  asset test, which  requires that no more
than a DE MINIMIS portion of  the assets of the REMIC  Pool, as of the close  of
the  third calendar month beginning after  the "Startup Day" (which for purposes
of this discussion is the date of issuance of the REMIC Certificates) and at all
times thereafter, may  consist of  assets other than  "qualified mortgages"  and
"permitted  investments."  The Proposed  REMIC Regulations  provide that  the DE
MINIMIS requirement is met if at all  times the aggregate adjusted basis of  the
nonqualified  assets is less than 1% of  the aggregate adjusted basis of all the
REMIC Pool's  assets.  An  entity  that  fails  to  meet  the  safe  harbor  may
nevertheless  demonstrate that  it holds  no more  than a  DE MINIMIS  amount of
nonqualified assets.
 
    A qualified mortgage  is any obligation  that is principally  secured by  an
interest  in real property and  that is either transferred  to the REMIC Pool on
the Startup Day or is  purchased by the REMIC  Pool within a three-month  period
thereafter  pursuant to  a fixed  price contract in  effect on  the Startup Day.
Qualified mortgages include whole  mortgage loans, such  as the Mortgage  Loans,
and,  generally, certificates  of beneficial  interest in  a grantor  trust that
holds mortgage  loans  and  regular  interests in  another  REMIC.  A  qualified
mortgage  includes a qualified replacement mortgage,  which is any property that
would have been treated as  a qualified mortgage if  it were transferred to  the
REMIC  Pool on the Startup  Day and that is received  either (i) in exchange for
any qualified  mortgage  within  a  three-month period  thereafter  or  (ii)  in
exchange  for a  "defective obligation" within  a two-year  period thereafter. A
"defective obligation" includes (i) a mortgage in default or as to which default
is  reasonably  foreseeable,   (ii)  a   mortgage  as  to   which  a   customary
representation  or warranty made at  the time of transfer  to the REMIC Pool has
been breached, (iii) a mortgage that was fraudulently procured by the mortgagor,
and (iv) a mortgage that  was not in fact  principally secured by real  property
(but  only  if such  mortgage is  disposed of  within 90  days of  discovery). A
Mortgage Loan that is "defective" as described  in clause (iv) that is not  sold
or,  if  within  two years  of  the Startup  Day,  exchanged within  90  days of
discovery, ceases to be a qualified mortgage after such 90-day period.
 
    Permitted investments  include  cash  flow  investments,  qualified  reserve
assets,  and foreclosure  property. A cash  flow investment is  an investment of
amounts received  on or  with respect  to qualified  mortgages for  a  temporary
period,  not  exceeding  13 months,  until  the next  scheduled  distribution to
holders of interests in the REMIC Pool,  and such investment must earn a  return
in  the nature of interest. A qualified reserve asset is any intangible property
held for investment that is part  of any reasonably required reserve  maintained
by  the REMIC Pool to provide  for payments of expenses of  the REMIC Pool or to
provide additional  security  for  payments  due  on  the  regular  or  residual
interests  that otherwise  may be delayed  or defaulted upon  because of default
(including delinquencies)  on the  qualified mortgages  or lower  than  expected
reinvestment  returns. It is  currently unclear whether  reserve funds for other
purposes (such as a reserve fund in connection with the use of graduated payment
mortgages) constitute  qualified  reserve  assets.  The  reserve  fund  will  be
disqualified  if more than 30% of the gross  income from the assets in such fund
for the year is derived from the sale or other disposition of property held  for
less  than three  months, unless  required to prevent  a default  on the regular
interests caused by a default on one or more qualified mortgages. A reserve fund
must be reduced "promptly and appropriately"  as payments on the Mortgage  Loans
are  received. Foreclosure property is real  property acquired by the REMIC Pool
in connection with the default or  imminent default of a qualified mortgage  and
generally held for not more than two years, with possible extensions.
 
    In  addition to the foregoing requirements, the various interests in a REMIC
Pool also must meet certain requirements. All  of the interests in a REMIC  Pool
must be either of the following: (i) one or more
 
                                       68
<PAGE>
classes  of regular interests  or (ii) a  single class of  residual interests on
which distributions,  if  any, are  made  pro rata.  A  regular interest  is  an
interest  in a REMIC Pool that is issued on the Startup Day with fixed terms, is
designated as a  regular interest,  and unconditionally entitles  the holder  to
receive  a specified  principal amount (or  other similar  amount), and provides
that interest payments (or other similar amounts), if any, at or before maturity
either are  payable based  on a  fixed rate  or a  qualified variable  rate,  or
consist of a specified, nonvarying portion of the interest payments on qualified
mortgages.  Under the Proposed REMIC Regulations, the specified principal amount
of a  regular interest  that  provides for  interest  payments consisting  of  a
specified, nonvarying portion of interest payments on qualified mortgages may be
zero.  A residual interest is  an interest in a REMIC  Pool other than a regular
interest that is issued on the Startup Day and that is designated as a  residual
interest.  The Proposed  REMIC Regulations provide  that an interest  in a REMIC
Pool may be treated  as a regular  interest even if  payments of principal  with
respect to such interest are subordinated to payments on other regular interests
or  the residual interest in the REMIC Pool, and are dependent on the absence of
defaults or delinquencies on qualified mortgages or permitted investments, lower
than reasonably expected returns on permitted investments, expenses incurred  by
the  REMIC  Pool or  prepayment  interest shortfalls.  Accordingly,  the Regular
Certificates of  a  Series  will  constitute one  or  more  classes  of  regular
interests,  and  the  Residual Certificates  with  respect to  that  Series will
constitute a single class of residual interests on which distributions are  made
pro rata.
 
    If  an entity, such as the  REMIC Pool, fails to comply  with one or more of
the ongoing requirements of the Code  for REMIC status during any taxable  year,
the  Code provides that the entity will not  be treated as a REMIC for such year
and thereafter. In  this event,  an entity  with multiple  classes of  ownership
interests  may be  treated as  a separate  association taxable  as a corporation
under Treasury  regulations, and  the  Regular Certificates  may be  treated  as
equity  interests therein. The Code, however, authorizes the Treasury Department
to issue regulations that address situations  where failure to meet one or  more
of the requirements for REMIC status occurs inadvertently and in good faith, and
disqualification  of  the  REMIC  Pool  would  occur  absent  regulatory relief.
Investors should be aware, however, that the Conference Committee Report to  the
1986  Act indicates that the relief may be accompanied by sanctions, such as the
imposition of a corporate tax on all or a portion of the REMIC Pool's income for
the period of time in which the requirements for REMIC status are not satisfied.
 
TAXATION OF REGULAR CERTIFICATES
 
  GENERAL
 
    In general,  interest, original  issue discount,  and market  discount on  a
Regular  Certificate  will be  treated as  ordinary  income to  a holder  of the
Regular Certificate (the "Regular Certificateholder"), and principal payments on
a Regular Certificate will be  treated as a return of  capital to the extent  of
the  Regular  Certificateholder's  basis in  the  Regular  Certificate allocable
thereto. Regular Certificateholders  must use the  accrual method of  accounting
with  regard to  Regular Certificates,  regardless of  the method  of accounting
otherwise used by such Regular Certificateholders.
 
  ORIGINAL ISSUE DISCOUNT
 
    Compound Interest  Certificates  will  be,  and  other  classes  of  Regular
Certificates may be, issued with "original issue discount" within the meaning of
Code  Section 1273(a). Holders of any  Class or Subclass of Regular Certificates
having original issue discount generally must include original issue discount in
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
following  discussion is  based in part  on proposed  Treasury regulations under
Code Sections 1271 through 1273 and 1275 (the "Proposed OID Regulations") and in
part on the  provisions of the  1986 Act. Regular  Certificateholders should  be
aware,  however, that  the Proposed  OID Regulations  do not  adequately address
certain   issues   relevant    to   prepayable   securities,    such   as    the
 
                                       69
<PAGE>
Regular  Certificates, and are  subject to change and  are not binding authority
before being adopted as final or  temporary regulations. However, to the  extent
adopted  as currently  drafted, the  Proposed OID  Regulations may  apply to the
Regular Certificates retroactively as binding authority.
 
    Under the Proposed OID Regulations, each Regular Certificate will be treated
as a  single installment  obligation for  purposes of  determining the  original
issue  discount includible  in a  Regular Certificateholder's  income. The total
amount of original issue discount on a Regular Certificate is the excess of  the
"stated redemption price at maturity" of the Regular Certificate over its "issue
price."  The  issue price  of  a Regular  Certificate is  the  price at  which a
substantial amount of Regular Certificates of  that Class are first sold to  the
public.  The issue price of a Regular  Certificate also includes the amount paid
by an initial Regular Certificateholder for  accrued interest that relates to  a
period prior to the issue date of the Regular Certificate. The stated redemption
price  at  maturity  of  a  Regular  Certificate  always  includes  the original
principal amount  of (in  the  case of  Standard  or Stripped  Certificates)  or
initial  Stated Amount of (in the  case of Multi-Class Certificates) the Regular
Certificate, but generally will not include distributions of stated interest  if
such  interest distributions constitute  "qualified periodic interest payments."
Under the  Proposed  OID  Regulations, a  qualified  periodic  interest  payment
generally  means interest payable at a single fixed rate or a qualified variable
rate (as described below) provided that such interest payments are actually  and
unconditionally  payable at fixed, periodic intervals of one year or less during
the entire  term of  the Regular  Certificate. Distributions  of interest  on  a
Compound  Interest Certificate, or on other Regular Certificates with respect to
which deferred  interest  will accrue,  may  not constitute  qualified  periodic
interest payments, in which case the stated redemption price at maturity of such
Regular Certificates includes all distributions of interest as well as principal
thereon.  Moreover,  if  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 Internal  Revenue Service could contend that
the initial interval should be divided into a short accrual period followed by a
period corresponding to the interval between subsequent Distribution Dates,  and
that  because no  distribution of interest  is made  on the date  that the short
accrual  period  ends,  the  stated  interest  distributions  on  such   Regular
Certificate do not constitute qualified periodic interest payments. Accordingly,
the  Internal  Revenue  Service could  contend  that all  distributions  on such
Regular Certificate  should be  includible  in the  stated redemption  price  at
maturity,  or that some other adjustment  should be made. Furthermore, a portion
of the interest  distributed on the  first Distribution Date  may be treated  as
nonqualified  periodic  interest includible  in the  stated redemption  price at
maturity to the extent such interest distribution is attributable to a period in
excess of the number of days between the issue date and such first  Distribution
Date.  Regular  Certificateholders  should  consult their  own  tax  advisors to
determine the issue price and stated  redemption price at maturity of a  Regular
Certificate.
 
    Under  a DE MINIMIS  rule, original issue discount  on a Regular Certificate
will be considered to be zero if such original issue discount is less than 0.25%
of the stated redemption price at maturity of the Regular Certificate multiplied
by the weighted average maturity of  the Regular Certificate. For this  purpose,
the  weighted average maturity of the Regular Certificate is computed as the sum
of the  amounts  determined by  multiplying  the  number of  full  years  (I.E.,
rounding  down partial  years) from  the issue  date until  each distribution in
reduction of stated redemption price  at maturity is scheduled  to be made by  a
fraction,  the numerator of which is the amount of each distribution included in
the stated  redemption price  at maturity  of the  Regular Certificate  and  the
denominator  of which is the stated redemption  price at maturity of the Regular
Certificate. Although currently unclear,  it appears that  the schedule of  such
distributions  should  be  determined in  accordance  with the  assumed  rate of
prepayment of the Mortgage Loans and the anticipated reinvestment rate, if  any,
relating   to  the  Regular  Certificates  (the  "Prepayment  Assumption").  The
Prepayment Assumption with respect to a  Series of Regular Certificates will  be
set forth in the related Prospectus Supplement.
 
    A  Regular Certificateholder generally must include  in gross income for any
taxable year the sum of the "daily portions," as defined below, of the  original
issue  discount on the Regular Certificate  accrued during an accrual period for
each day  on which  it holds  the  Regular Certificate,  including the  date  of
 
                                       70
<PAGE>
purchase  but excluding the  date of disposition. Although  not free from doubt,
the Seller intends to treat the monthly period ending on each Distribution  Date
as the accrual period, rather than the monthly period corresponding to the prior
calendar  month. With respect to each Regular Certificate, a calculation will be
made of the  original issue discount  that accrues during  each successive  full
accrual  period (or shorter period from the date of original issue) that ends on
the related  Distribution  Date  on  the  Regular  Certificate.  The  Conference
Committee  Report to the  1986 Act states  that the rate  of accrual of original
issue discount  is  intended to  be  based  on the  Prepayment  Assumption.  The
original  issue discount accruing in a full  accrual period would be the excess,
if any,  of (i)  the  sum of  (a) the  present  value of  all of  the  remaining
distributions  to  be made  on the  Regular Certificate  as of  the end  of that
accrual period that are included in the Regular Certificate's stated  redemption
price  at maturity,  and (b) the  distributions made on  the Regular Certificate
during the accrual period that are included in the Regular Certificate's  stated
redemption  price at maturity, over (ii) the adjusted issue price of the Regular
Certificate at the  beginning of the  accrual period. The  present value of  the
remaining  distributions  referred to  in the  preceding sentence  is calculated
based on (i) the yield to maturity of the Regular Certificate at the issue date,
(ii) events (including actual prepayments) that  have occurred prior to the  end
of  the accrual period, and (iii) the Prepayment Assumption. For these purposes,
the adjusted  issue price  of a  Regular  Certificate at  the beginning  of  any
accrual  period equals the issue price  of the Regular Certificate, increased by
the aggregate amount  of original  issue discount  with respect  to the  Regular
Certificate  that accrued in all prior accrual periods and reduced by the amount
of distributions included in the  Regular Certificate's stated redemption  price
at maturity that were made on the Regular Certificate in such prior periods. The
original  issue discount  accruing during any  accrual period  (as determined in
this paragraph) will  then be divided  by the number  of days in  the period  to
determine  the daily  portion of  original issue  discount for  each day  in the
period. With respect to  an initial accrual period  shorter than a full  accrual
period,  the  daily  portions  of original  issue  discount  must  be determined
according to  an appropriate  allocation under  either an  exact or  approximate
method  set  forth in  the  Proposed OID  Regulations  or some  other reasonable
method, provided  that  such  method  is consistent  with  the  method  used  to
determine the yield to maturity of the Regular Certificate.
 
    Under  the  method described  above, the  daily  portions of  original issue
discount required  to  be included  in  income by  a  Regular  Certificateholder
generally  will  increase  to  take  into  account  prepayments  on  the Regular
Certificates as a result  of prepayments on the  Mortgage Loans that exceed  the
Prepayment  Assumption, and generally will decrease  (but not below zero for any
period) if the  prepayments are slower  than the Prepayment  Assumption. To  the
extent  specified  in  the  applicable  Prospectus  Supplement,  an  increase in
prepayments  on  the  Mortgage  Loans  with  respect  to  a  Series  of  Regular
Certificates  can result in both a change  in the priority of principal payments
with respect to certain Classes of  Regular Certificates and either an  increase
or  decrease in the  daily portions of  original issue discount  with respect to
such Regular Certificates.
 
    A purchaser of a  Regular Certificate at a  price greater than its  "revised
issue  price," as defined below, will be required to include in gross income the
daily portions of the original issue discount on the Regular Certificate reduced
pro rata by a  fraction, the numerator  of which is the  excess of its  purchase
price  over  such  revised issue  price  and  the denominator  of  which  is the
remaining original  issue  discount.  The  revised  issue  price  of  a  Regular
Certificate  is  the sum  of its  original  issue price  and the  original issue
discount that would have been previously accrued by an original holder less  any
prior distributions included in the stated redemption price at maturity.
 
  VARIABLE RATE REGULAR CERTIFICATES
 
    Regular  Certificates may  provide for  interest based  on a  variable rate.
Under the  Proposed  OID  Regulations, a  qualified  periodic  interest  payment
includes any one of a series of payments equal to the product of the outstanding
principal  balance of a Regular Certificate and a variable rate tied to a single
objective index of market interest  rates, provided that such interest  payments
are  actually and  unconditionally payable at  fixed, periodic  intervals of one
year or less during the entire term of the Regular Certificate. In the case of a
Regular Certificate,  however, that  pays  interest based  on a  combination  of
 
                                       71
<PAGE>
fixed  or qualifying variable rates or at a variable rate that is subject to one
or more maximum rate ceilings or certain other adjustments, it is unclear  under
the  Proposed  OID  Regulations  whether interest  payments  on  such  a Regular
Certificate constitute  qualified periodic  interest  payments, or  instead  are
either  includible in  the stated  redemption price  at maturity  of the Regular
Certificate or treated as contingent  interest payments includible in income  as
they  become fixed.  Further, the  Proposed REMIC  Regulations generally provide
that a Regular  Certificate (i)  bearing a floating  rate tied  to an  objective
index  (or the highest, lowest  or average of two  or more objective indices) of
market interest rates (including a  rate based on the  average cost of funds  of
one  or more  financial institutions) or  that represents a  weighted average of
rates on some or all of  the Mortgage Loans that bear  either a fixed rate or  a
qualifying  variable rate, including such a rate  that is subject to one or more
caps or floors, or (ii) bearing one  or more such qualifying variable rates  for
one  or  more periods,  or one  or more  fixed  rates for  one or  more periods,
qualifies as a regular interest in a REMIC.
 
    The amount of original issue discount with respect to a Regular  Certificate
bearing  a variable rate of  interest will accrue in  the manner described above
under "Original Issue Discount," with the yield to maturity and future  payments
on  such Regular Certificate to be determined by assuming that the interest rate
index applicable to the first Distribution Date remains constant throughout  the
life  of the Regular Certificate. Ordinary income reportable for any period will
be adjusted based on subsequent changes  in the applicable interest rate  index.
Where  the issue price  of a Regular Certificate  exceeds the original principal
amount or Stated Amount  of the Regular Certificate,  it appears appropriate  to
reduce the ordinary income reportable for an accrual period by a portion of such
excess  in a manner  similar to the  amortization of premium  on the level yield
method. Absent clarification, original  issue discount will  be reported to  the
Internal Revenue Service and to holders of variable rate Regular Certificates in
the manner described in this paragraph using the Prepayment Assumption.
 
    In  the case  of Regular  Certificates bearing  an interest  rate that  is a
weighted average of the net interest  rates on Mortgage Loans having  adjustable
rates,  the applicable index used  to compute interest on  the Mortgage Loans in
effect on the issue date (or possibly the pricing date) will be deemed to be  in
effect  beginning with the period in which the first weighted average adjustment
date occurring after the issue date occurs. If the Pass-Through Rate for one  or
more  periods is less  than it would be  based upon the  fully indexed rate, the
excess of the  interest payments projected  at the assumed  index over  interest
projected  at such initial  rate may be  treated as original  issue discount. In
such case, a  Regular Certificateholder may  have ordinary income  in excess  of
interest  received at the initial Pass-Through Rate. An adjustment would be made
in each period  either increasing or  decreasing the amount  of ordinary  income
reportable  to reflect the actual Pass-Through  Rate on the Regular Certificate.
Unless and until clarified by  applicable Treasury regulations, the Seller  does
not intend to report such excess as original issue discount.
 
  MARKET DISCOUNT
 
    A  purchaser of  a Regular  Certificate also  may be  subject to  the market
discount rules of Code Sections 1276 through 1278. Under these sections and  the
principles  applied by the  Proposed OID Regulations in  the context of original
issue discount,  "market  discount"  is  the amount  by  which  the  purchaser's
original  basis in the  Regular Certificate (i) is  exceeded by the then-current
principal amount of the Regular  Certificate, or (ii) in  the case of a  Regular
Certificate  having original  issue discount, is  exceeded by  the revised issue
price of such Regular Certificate at  the time of purchase, as described  above.
Such  purchaser generally will  be required to recognize  ordinary income to the
extent of accrued market discount  on such Regular Certificate as  distributions
includible  in the stated redemption price  at maturity thereof are received, in
an amount not exceeding any such distribution. Such market discount would accrue
in a manner to be provided in Treasury regulations and should take into  account
the  Prepayment  Assumption. The  Conference Committee  Report  to the  1986 Act
provides that  until such  regulations are  issued, such  market discount  would
accrue either (i) on the basis of a constant interest rate, or (ii) in the ratio
of  stated interest allocable to the relevant  period to the sum of the interest
for such period plus the remaining interest as of the end of such period, or  in
the case of a Regular Certificate
 
                                       72
<PAGE>
issued  with original  issue discount, in  the ratio of  original issue discount
accrued for  the relevant  period to  the  sum of  the original  issue  discount
accrued for such period plus the remaining original issue discount as of the end
of  such  period. Such  purchaser also  generally  will be  required to  treat a
portion of any gain on a sale or exchange of the Regular Certificate as ordinary
income to the extent of the market  discount accrued to the date of  disposition
under  one of the foregoing methods, less any accrued market discount previously
reported as ordinary income as partial distributions in reduction of the  stated
redemption  price at maturity were received.  Such purchaser will be required to
defer deduction of a portion  of the excess of the  interest paid or accrued  on
indebtedness  incurred  to  purchase or  carry  a Regular  Certificate  over the
interest distributable thereon. The deferred portion of such interest expense in
any taxable year generally  will not exceed the  accrued market discount on  the
Regular  Certificate for  such year. Any  such deferred interest  expense is, in
general, allowed as a  deduction not later  than the year  in which the  related
market  discount income is recognized or the Regular Certificate is disposed of.
As an alternative to the inclusion of market discount in income on the foregoing
basis, the Regular  Certificateholder may  elect to include  market discount  in
income  currently as it  accrues on all market  discount instruments acquired by
such Regular Certificateholder in that taxable year or thereafter, in which case
the interest deferral rule will not apply.
 
    By analogy to the Proposed OID Regulations, market discount with respect  to
a  Regular Certificate will be considered to  be zero if such market discount is
less than 0.25%  of the remaining  stated redemption price  at maturity of  such
Regular  Certificate multiplied by the weighted  average maturity of the Regular
Certificate (determined  as  described  above  in  the  fourth  paragraph  under
"Original  Issue  Discount")  remaining  after the  date  of  purchase. Treasury
regulations implementing the market discount rules have not yet been issued, and
therefore  investors  should  consult  their  own  tax  advisors  regarding  the
application  of these  rules as well  as the  advisability of making  any of the
elections with respect thereto.
 
  PREMIUM
 
    A Regular Certificate purchased at a cost greater than its remaining  stated
redemption  price  at maturity  generally  is considered  to  be purchased  at a
premium. If the Regular  Certificateholder holds such  Regular Certificate as  a
"capital   asset"  within  the  meaning  of   Code  Section  1221,  the  Regular
Certificateholder may  elect under  Code Section  171 to  amortize such  premium
under  the constant interest method. The Conference Committee Report to the 1986
Act indicates a Congressional intent that the same rules that will apply to  the
accrual  of  market  discount  on installment  obligations  will  also  apply to
amortizing bond premium under Code  Section 171 on installment obligations  such
as  the Regular Certificates, although it is unclear whether the alternatives to
the constant  interest  method  described  above  under  "Market  Discount"  are
available.  Amortizable bond  premium will be  treated as an  offset to interest
income on a Regular Certificate, rather than as a separate deduction item.
 
  SALE OR EXCHANGE OF REGULAR CERTIFICATES
 
    If a Regular Certificateholder sells or exchanges a Regular Certificate, the
Regular Certificateholder will recognize gain  or loss equal to the  difference,
if  any,  between the  amount received  and  its adjusted  basis in  the Regular
Certificate. The adjusted basis  of a Regular  Certificate generally will  equal
the  cost of the  Regular Certificate to  the seller, increased  by any original
issue discount  or market  discount previously  included in  the seller's  gross
income  with respect to the Regular  Certificate and reduced by amounts included
in the stated redemption price at maturity of the Regular Certificate that  were
previously received by the seller and by any amortized premium.
 
    Except  as described  above with respect  to market discount,  and except as
provided in  this paragraph,  any gain  or loss  on the  sale or  exchange of  a
Regular Certificate realized by an investor who holds the Regular Certificate as
a capital asset will be capital gain or loss and will be long-term or short-term
depending  on whether  the Regular Certificate  has been held  for the long-term
capital gain  holding period  (currently, more  than one  year). Gain  from  the
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
 
                                       73
<PAGE>
the  excess, if any,  of (i) the amount  that would have  been includible in the
gross income of the holder if his yield on such Regular Certificate were 110% of
the applicable  Federal  rate under  Code  Section 1274(d)  as  of the  date  of
purchase, over (ii) the amount of income actually includible in the gross income
of  such holder with  respect to the  Regular Certificate. In  addition, gain or
loss recognized  from the  sale of  a Regular  Certificate by  certain banks  or
thrift  institutions will be treated as ordinary income or loss pursuant to Code
Section 582(c). The  preferential rates  applicable to  long-term capital  gains
were eliminated by the 1986 Act. However, the Revenue Reconciliation Act of 1990
restored  a preferential rate applicable to long-term capital gains with respect
to certain individuals.
 
TAXATION OF RESIDUAL CERTIFICATES
 
  TAXATION OF REMIC INCOME
 
    Generally, the "daily portions" of REMIC taxable income or net loss will  be
includible  as ordinary income or loss in determining the federal taxable income
of holders of Residual Certificates ("Residual Holders"), and will not be  taxed
separately  to the REMIC Pool. The daily portions of REMIC taxable income or net
loss of a Residual Holder are determined by allocating the REMIC Pool's  taxable
income or net loss for each calendar quarter ratably to each day in such quarter
and by allocating such daily portion among the Residual Holders in proportion to
their  respective holdings  of Residual Certificates  in the REMIC  Pool on such
day. 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 limitation  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 will apply. REMIC taxable
income generally  means  the  REMIC Pool's  gross  income,  including  interest,
original  issue  discount income,  and market  discount income,  if any,  on the
Mortgage Loans, plus income  on reinvestment of cash  flows and reserve  assets,
minus  deductions, including interest and original issue discount expense on the
Regular  Certificates,  servicing   fees  on  the   Mortgage  Loans  and   other
administrative  expenses of the REMIC Pool, and amortization of premium, if any,
with respect to the Mortgage Loans. The requirement that Residual Holders report
their pro  rata share  of taxable  income or  net loss  of the  REMIC Pool  will
continue  until there  are no  Certificates of any  class of  the related Series
outstanding.
 
    The taxable income recognized by a Residual Holder in any taxable year  will
be  affected by,  among other  factors, the  relationship between  the timing of
recognition of interest and original issue discount or market discount income or
amortization of premium with respect to the Mortgage Loans, on the one hand, and
the timing of deductions for interest (including original issue discount) on the
Regular Certificates, on the other  hand. In the event  that an interest in  the
Mortgage  Loans is acquired by the REMIC Pool  at a discount, and one or more of
such Mortgage Loans is prepaid, the Residual Holder may recognize taxable income
without being entitled to receive a corresponding amount of cash because (i) the
prepayment may be used in whole or in part to make distributions in reduction of
principal or Stated Amount on the Regular Certificates, and (ii) the discount on
the Mortgage  Loans which  is  includible in  income  may exceed  the  deduction
allowed  upon such distributions on those Regular Certificates on account of any
unaccrued original issue discount relating  to those Regular Certificates.  When
there  is more than one Class  of Regular Certificates that distribute principal
or payments  in reduction  of Stated  Amount sequentially,  this mismatching  of
income  and  deductions  is particularly  likely  to  occur in  the  early years
following issuance of the Regular  Certificates when distributions in  reduction
of  principal or Stated Amount  are being made in  respect of earlier Classes of
Regular Certificates  to  the extent  that  such  Classes are  not  issued  with
substantial  discount. If taxable  income attributable to  such a mismatching is
realized, in general, losses would be allowed in later years as distributions on
the later Classes of Regular Certificates  are made. Taxable income may also  be
greater  in earlier  years than  in later  years as  a result  of the  fact that
interest expense  deductions,  expressed  as a  percentage  of  the  outstanding
principal  amount of  such a Series  of Regular Certificates,  may increase over
time as distributions in reduction of principal or Stated Amount are made on the
lower yielding Classes  of Regular  Certificates, whereas  interest income  with
respect to any given Mortgage Loan will remain
 
                                       74
<PAGE>
constant  over time as a percentage of  the outstanding principal amount of that
loan. Consequently, Residual Holders must have sufficient other sources of  cash
to  pay  any federal,  state, or  local income  taxes  due as  a result  of such
mismatching or unrelated deductions against which to offset such income, subject
to the discussion of "excess inclusions"  below under "Limitations on Offset  or
Exemption  of  REMIC  Income." The  timing  of  such mismatching  of  income and
deductions described in this paragraph, if  present with respect to a Series  of
Certificates,  may have a significant adverse  effect upon the Residual Holder's
after-tax rate of return. In addition, a Residual Holder's taxable income during
certain periods may exceed the income reflected by such Residual Holder for such
periods in accordance with  generally accepted accounting principles.  Investors
should  consult  their own  accountants concerning  the accounting  treatment of
their investment in Residual Certificates.
 
  BASIS AND LOSSES
 
    The amount of any net loss of the REMIC Pool that may be taken into  account
by  the  Residual  Holder is  limited  to  the adjusted  basis  of  the Residual
Certificate as  of the  close of  the quarter  (or time  of disposition  of  the
Residual Certificate if earlier), determined without taking into account the net
loss  for the quarter. The  initial adjusted basis of  a purchaser of a Residual
Certificate is  the amount  paid for  such Residual  Certificate. Such  adjusted
basis  will  be increased  by the  amount of  taxable income  of the  REMIC Pool
reportable by the Residual  Holder and will be  decreased (but not below  zero),
first,  by a cash distribution from the REMIC Pool and, second, by the amount of
loss of the  REMIC Pool  reportable by  the Residual  Holder. Any  loss that  is
disallowed  on account of this limitation  may be carried over indefinitely with
respect to the Residual Holder  as to whom such loss  was disallowed and may  be
used  by such Residual  Holder only to  offset any income  generated by the same
REMIC Pool.
 
    A Residual Holder will not be permitted to amortize directly the cost of its
Residual Certificate as  an offset to  its share  of the taxable  income of  the
related  REMIC Pool. However, that taxable income will not include cash received
by the REMIC Pool that  represents a recovery of the  REMIC Pool's basis in  its
assets.  Such  recovery of  basis  by the  REMIC Pool  will  have the  effect of
amortization of the issue  price of the Residual  Certificates over their  life.
However,  in view of the possible acceleration of the income of Residual Holders
described above under "Taxation of REMIC Income," the period of time over  which
such  issue price is effectively amortized may  be longer than the economic life
of the Residual Certificates.
 
    A Residual Certificate may have a negative value if the net present value of
anticipated tax liabilities exceeds the present value of anticipated cash flows.
In such event, it is unclear whether  its issue price would be considered to  be
zero  or such negative amount for purposes of determining the REMIC Pool's basis
in its assets. The  Proposed REMIC Regulations do  not address whether  residual
interests  could have a negative basis and  a negative issue price. However, the
preamble to the Proposed  REMIC Regulations indicates  that, while existing  tax
rules  do  not  accommodate  such  concepts,  the  Internal  Revenue  Service is
considering the tax treatment  of these types  of residual interests,  including
whether  such residual interests may  have a negative basis  or a negative issue
price. The Seller does not intend to  treat a Class of Residual Certificates  as
having  a value of less  than zero for purposes of  determining the basis of the
related REMIC Pool in its assets.
 
    Further, to the extent that the initial adjusted basis of a Residual  Holder
(other  than an original holder) in the Residual Certificate is greater than the
corresponding portion  of the  REMIC Pool's  basis in  the Mortgage  Loans,  the
Residual  Holder will not recover  a portion of such  basis until termination of
the REMIC Pool unless Treasury regulations yet to be issued provide for periodic
adjustments to  the  REMIC  income  otherwise reportable  by  such  holder.  The
Proposed REMIC Regulations do not so provide. See "Treatment of Certain Items of
REMIC Income and Expense--Market Discount" below regarding the basis of Mortgage
Loans  to the REMIC Pool and "Sale  or Exchange of a Residual Certificate" below
regarding possible treatment of a loss upon  termination of the REMIC Pool as  a
capital loss.
 
                                       75
<PAGE>
  TREATMENT OF CERTAIN ITEMS OF REMIC INCOME AND EXPENSE
 
    ORIGINAL  ISSUE  DISCOUNT.    Generally,  the  REMIC  Pool's  deductions for
original issue discount will be determined in the same manner as original  issue
discount  income on Regular  Certificates as described  above under "Taxation of
Regular Certificates--Original  Issue  Discount" and  "--Variable  Rate  Regular
Certificates," without regard to the DE MINIMIS rule described therein.
 
    MARKET DISCOUNT.  The REMIC Pool will have market discount income in respect
of  Mortgage Loans if, in general, the basis  of the REMIC Pool in such Mortgage
Loans is exceeded by their unpaid principal balances. The REMIC Pool's basis  in
such  Mortgage Loans is  generally the fair  market value of  the Mortgage Loans
immediately after the  transfer thereof to  the REMIC Pool.  The Proposed  REMIC
Regulations  provide that  such basis  is equal  in the  aggregate to  the issue
prices of all regular and  residual interests in the  REMIC Pool. In respect  of
Mortgage Loans that have market discount to which Code Section 1276 applies, the
accrued portion of such market discount would be recognized currently as an item
of ordinary income. Market discount income generally should accrue in the manner
described  above  under  "Taxation  of  Regular  Certificates--Market Discount."
However, the rules of Code Section  1276 concerning market discount income  will
not apply in the case of Mortgage Loans originated on or prior to July 18, 1984,
if  any.  With respect  to  such Mortgage  Loans,  market discount  is generally
includible in  REMIC  taxable  income  or ordinary  gross  income  pro  rata  as
principal  payments are  received. The  deduction of  a portion  of the interest
expense on the Regular Certificates allocable  to such discount may be  deferred
until  such discount is included in income, and any gain on the sale or exchange
thereof will  be  treated as  ordinary  income to  the  extent of  the  deferred
interest deductible at that time.
 
    PREMIUM.   Generally, if the  basis of the REMIC  Pool in the Mortgage Loans
exceeds the unpaid principal balances thereof, the REMIC Pool will be considered
to have acquired such Mortgage  Loans at a premium equal  to the amount of  such
excess.  As stated above, the  REMIC Pool's basis in  Mortgage Loans is the fair
market value of the Mortgage Loans, based  on the aggregate of the issue  prices
of  the regular and residual  interests in the REMIC  Pool immediately after the
transfer thereof to  the REMIC  Pool. In a  manner analogous  to the  discussion
above  under "Taxation of Regular Certificates--Premium,"  a person that holds a
Mortgage Loan as a capital  asset under Code Section  1221 may elect under  Code
Section 171 to amortize premium on Mortgage Loans originated after September 27,
1985  under a constant interest method. Amortizable bond premium will be treated
as an offset to interest income on the Mortgage Loans, rather than as a separate
deduction item.  Because substantially  all of  the mortgagors  on the  Mortgage
Loans are expected to be individuals, Code Section 171 will not be available for
premium  on Mortgage Loans originated on or prior to September 27, 1985. Premium
with respect  to such  Mortgage Loans  may be  deductible in  accordance with  a
reasonable  method regularly employed  by the holder  thereof. The allocation of
such premium pro rata among principal payments should be considered a reasonable
method; however, the Internal Revenue Service may argue that such premium should
be allocated in a different manner, such as allocating such premium entirely  to
the final payment of principal.
 
  LIMITATIONS ON OFFSET OR EXEMPTION OF REMIC INCOME
 
    The  Code  provides that,  to  the extent  provided  in regulations,  if the
aggregate value of the Residual Certificates relative to the aggregate value  of
the   Regular  Certificates  and  Residual  Certificates  is  considered  to  be
"significant," as described  below, then a  portion (but not  all) of the  REMIC
taxable  income includible in determining the  federal income tax liability of a
Residual Holder will be subject to special treatment. That portion, referred  to
as  the "excess inclusion," is  equal to the excess  of REMIC taxable income for
the calendar quarter allocable to a Residual Certificate over the daily accruals
for such quarterly period of (i)  120% of the long-term applicable Federal  rate
that  would  have  applied  to  the Residual  Certificate  (if  it  were  a debt
instrument) on the Startup  Day under Code Section  1274(d), multiplied by  (ii)
the  adjusted issue price of such Residual  Certificate at the beginning of such
quarterly period.  For this  purpose, the  adjusted issue  price of  a  Residual
Certificate  at the beginning  of a quarter  is the issue  price of the Residual
Certificate,  plus  the  amount   of  such  daily   accruals  of  REMIC   income
 
                                       76
<PAGE>
described   in  this  paragraph  for  all   prior  quarters,  decreased  by  any
distributions made  with  respect to  such  Residual Certificate  prior  to  the
beginning  of such quarterly period. Although the Conference Committee Report to
the 1986 Act  indicates that  the value of  all Residual  Certificates would  be
considered significant in cases where such value is at least 2% of the aggregate
value  of the Regular Certificates and Residual Certificates, the Proposed REMIC
Regulations do not adopt  such a general rule.  Accordingly, the portion of  the
REMIC  Pool's taxable income that  will be treated as  excess inclusions will be
determined by the preceding formula, with the effect that such excess inclusions
will be a larger portion  of such income as the  relative value of the  Residual
Certificates diminishes.
 
    The  portion of a  Residual Holder's REMIC taxable  income consisting of the
excess inclusions generally may not be offset by other deductions, including net
operating loss carryforwards, on such Residual Holder's return. Further, if  the
Residual  Holder is  an organization  subject to  the tax  on unrelated business
income imposed by Code Section 511, the Residual Holder's excess inclusions will
be treated as  unrelated business  taxable income  of such  Residual Holder  for
purposes  of Code Section 511.  In addition, REMIC taxable  income is subject to
30% withholding tax with respect to certain persons who are not U.S. Persons (as
defined  below  under   "Tax-Related  Restrictions  on   Transfer  of   Residual
Certificates--Foreign  Investors"),  and  the  portion  thereof  attributable to
excess inclusions is not eligible for  any reduction in the rate of  withholding
tax   (by   treaty   or   otherwise).   See   "Taxation   of   Certain   Foreign
Investors--Residual Certificates" below. Finally, under Treasury regulations yet
to be issued, if a real estate  investment trust owns a Residual Certificate,  a
portion  of dividends  paid by  the real  estate investment  trust could  not be
offset by net operating losses  of its shareholders, would constitute  unrelated
business taxable income for tax-exempt shareholders, and would be ineligible for
reduction  of  withholding to  certain persons  who are  not U.S.  Persons. This
treatment may be  extended under  Treasury regulations  to regulated  investment
companies, common trust funds, and certain cooperatives.
 
    An  exception  to  the  inability  of a  Residual  Holder  to  offset excess
inclusions with unrelated deductions  and net operating  losses applies to  Code
Section  593 institutions ("thrift institutions"). For purposes of applying this
rule, all  members of  an  affiliated group  filing  a consolidated  return  are
treated  as one taxpayer, except that  thrift institutions to which Code Section
593 applies,  together  with their  subsidiaries  formed to  issue  REMICs,  are
treated   as  separate   corporations.  Furthermore,  the   Code  provides  that
regulations may disallow the ability of  a thrift institution to use  deductions
to offset excess inclusions if necessary or appropriate to prevent the avoidance
of tax. The Proposed REMIC Regulations provide that a thrift institution may not
so   offset  its  excess  inclusions   unless  the  Residual  Certificates  have
"significant value," which requires that  (i) the Residual Certificates have  an
issue price that is at least equal to 2% of the aggregate of the issue prices of
all  Residual Certificates  and Regular Certificates  with respect  to the REMIC
Pool,  and  (ii)  the  anticipated   weighted  average  life  of  the   Residual
Certificates  is at least 20% of the  anticipated life (I.E., final maturity) of
the  REMIC  Pool.  The  anticipated  weighted  average  life  of  the   Residual
Certificates  is based on the anticipated principal payments to be recieved with
respect thereto (using the Prepayment  Assumption), except that all  anticipated
distributions  are to be used if the Residual Certificate is not entitled to any
principal payments,  or  is entitled  to  a disproportionately  small  principal
amount  relative  to interest  payments thereon.  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 Proposed  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. If applicable, the Prospectus Supplement  with respect to a Series  will
set  forth whether the  Residual Certificates are  expected to have "significant
value" within the meaning of the Proposed REMIC Regulations.
 
  TAX-RELATED RESTRICTIONS ON TRANSFER OF RESIDUAL CERTIFICATES
 
    DISQUALIFIED ORGANIZATIONS.    If any  legal  or beneficial  interest  in  a
Residual  Certificate is transferred to  a Disqualified Organization (as defined
below), a tax  would be imposed  in an amount  equal to the  product of (i)  the
present  value of the  total anticipated excess inclusions  with respect to such
Residual Certificate  for  periods  after  the transfer  and  (ii)  the  highest
marginal federal income tax rate applicable to
 
                                       77
<PAGE>
corporations. The Proposed REMIC Regulations provide that the anticipated excess
inclusions are based on actual prepayment experience to the date of the transfer
and  projected payments  based on the  Prepayment Assumption.  The present value
rate equals the  applicable federal rate  under Code Section  1274(d) as of  the
date  of the transfer for a  term equal to the remaining  term of the REMIC, and
such rate is applied to  the anticipated excess inclusions  from the end of  the
remaining  calendar quarters in  which they arise  to the date  of the transfer.
Such a  tax  generally  would be  imposed  on  the transferor  of  the  Residual
Certificate,  except that where  such transfer is through  an agent (including a
broker, nominee, or other  middleman) for a  Disqualified Organization, the  tax
would  instead be  imposed on  such agent. However,  a transferor  of a Residual
Certificate would in no event be liable for such tax with respect to a  transfer
if  the transferee furnishes to the  transferor an affidavit that the transferee
is not a  Disqualified Organization and,  as of  the time of  the transfer,  the
transferor  does not have actual knowledge that such affidavit is false. The tax
also may be waived by the  Treasury Department if the Disqualified  Organization
promptly disposes of the residual interest and the transferor pays income tax at
the  highest corporate rate on the excess  inclusion for the period the Residual
Certificate is actually held by the Disqualified Organization.
 
    In addition,  if  a "Pass-Through  Entity"  (as defined  below)  has  excess
inclusion  income with respect  to a Residual Certificate  during a taxable year
and a Disqualified Organization  is the record holder  of an equity interest  in
such  entity, then a tax is  imposed on such entity equal  to the product of (i)
the amount  of excess  inclusions that  are  allocable to  the interest  in  the
Pass-Through Entity during the period such interest is held by such Disqualified
Organization,  and (ii) the highest marginal  federal corporate income tax rate.
Such tax would be deductible from the ordinary gross income of the  Pass-Through
Entity  for the taxable  year. The Pass-Through  Entity would not  be liable for
such tax if it has received an affidavit from such record holder that it is  not
a  Disqualified Organization  or stating  such holder's  taxpayer identification
number and, during the period such person  is the record holder of the  Residual
Certificate,  the Pass-Through Entity  does not have  actual knowledge that such
affidavit is false.
 
    For these purposes, (i) "Disqualified Organization" means the United States,
any  state  or  political  subdivision  thereof,  any  foreign  government,  any
international  organization,  any  agency  or  instrumentality  of  any  of  the
foregoing (provided, that such term does  not include an instrumentality if  all
of its activities are subject to tax and a majority of its board of directors is
not  selected  by any  such governmental  entity), any  cooperative organization
furnishing electric energy or  providing telephone service  to persons in  rural
areas  as described in  Code Section 1381(a)(2)(C),  and any organization (other
than a farmers' cooperative described in  Code Section 521) that is exempt  from
taxation  under  the Code  unless such  organization  is subject  to the  tax on
unrelated business income imposed  by Code Section  511, and (ii)  "Pass-Through
Entity"  means any regulated  investment company, real  estate investment trust,
common trust  fund,  partnership,  trust  or  estate  and  certain  corporations
operating  on  a  cooperative  basis.  Except as  may  be  provided  in Treasury
regulations, any  person holding  an  interest in  a  Pass-Through Entity  as  a
nominee  for  another will,  with  respect to  such  interest, be  treated  as a
Pass-Through Entity.
 
    The Pooling and Servicing  Agreement with respect to  a Series will  provide
that  no  legal  or  beneficial  interest  in  a  Residual  Certificate  may  be
transferred or registered  unless (i)  the proposed transferee  provides to  the
Seller  and the Trustee an affidavit to the effect that such transferee is not a
Disqualified Organization,  is  not  purchasing such  Residual  Certificates  on
behalf  of a Disqualified Organization (I.E., as a broker, nominee, or middleman
thereof) and is not an entity that holds REMIC residual securities as nominee to
facilitate the clearance  and settlement of  such securities through  electronic
book-entry  changes  in accounts  of participating  organizations, and  (ii) the
transferor provides a statement in writing to the Seller and the Trustee that it
has no actual knowledge that such affidavit is false. Moreover, the Pooling  and
Servicing  Agreement will  provide that any  attempted or  purported transfer in
violation of these transfer restrictions will be null and void and will vest  no
rights  in any purported transferee. Each Residual Certificate with respect to a
Series will bear a legend referring  to such restrictions on transfer, and  each
Residual  Holder will  be deemed  to have  agreed, as  a condition  of ownership
thereof, to  any  amendments to  the  related Pooling  and  Servicing  Agreement
required  under the  Code or applicable  Treasury regulations  to effectuate the
foregoing
 
                                       78
<PAGE>
restrictions. Information necessary to compute an applicable excise tax must  be
furnished  to the Internal Revenue Service and to the requesting party within 60
days of  the request,  and  the Seller  or  the Trustee  may  charge a  fee  for
computing and providing such information.
 
    NONECONOMIC  RESIDUAL  INTERESTS.    The  Proposed  REMIC  Regulations would
disregard  certain  transfers  of  Residual  Certificates,  in  which  case  the
transferor   would  continue  to  be  treated  as  the  owner  of  the  Residual
Certificates and  thus would  continue to  be subject  to tax  on its  allocable
portion  of  the  net  income  of  the  REMIC  Pool.  Under  the  Proposed REMIC
Regulations, a transfer of a "noneconomic residual interest" (defined below)  to
a  Residual Holder (other  than a Residual Holder  who is not  a U.S. Person, as
defined below under "Foreign Investors")  is disregarded for all federal  income
tax  purposes unless  no significant  purpose of the  transfer is  to impede the
assessment or collection  of tax. A  residual interest in  a REMIC (including  a
residual  interest with a positive value at issuance) is a "noneconomic residual
interest" unless, at  the time of  the transfer,  (i) the present  value of  the
expected  future  distributions on  the residual  interest  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. The anticipated excess inclusions and the present value rate are
determined  in  the  same  manner   as  set  forth  above  under   "Disqualified
Organizations." The Proposed REMIC Regulations do not explain when a substantial
purpose  of  a  transfer  will be  deemed  to  be to  impede  the  assessment or
collection of tax.  While complete  assurance as to  how to  meet this  standard
cannot  be provided,  the Indenture  will require  the transferee  of a Residual
Certificate to state as part of the affidavit described above under the  heading
"Disqualified Organizations" that such transferee has no intention to impede the
assessment or collection of any federal, state or local income taxes required to
be  paid with respect to the Residual  Certificate, and the transferor must have
no reason to believe that such statement is untrue.
 
    FOREIGN INVESTORS.  The Proposed REMIC Regulations provide that the transfer
of a  Residual Certificate  that has  "tax avoidance  potential" to  a  "foreign
person"  will be  disregarded for  all federal  tax purposes.  This rule appears
intended to apply to a transferee who is not a "U.S. Person" (as defined below),
unless such transferee's income is effectively  connected with the conduct of  a
trade  or business within the United States. A Residual Certificate is deemed to
have tax avoidance potential unless, at the time of the transfer, (i) the future
value of expected distributions  equals at least 30%  of the anticipated  excess
inclusions  after the transfer, and (ii)  the transferor reasonably expects that
the transferee will receive sufficient distributions  from the REMIC Pool at  or
after  the  time  at which  the  excess  inclusions accrue  for  the accumulated
withholding  tax  liability  to  be   paid,  even  if  such  distributions   are
"substantially   deferred."  If  the  non-U.S.  Person  transfers  the  Residual
Certificate back to  a U.S.  Person, the transfer  will be  disregarded and  the
foreign  transferor will continue to be treated as the owner unless arrangements
are made  so  that  the transfer  does  not  have the  effect  of  allowing  the
transferor to avoid tax on accrued excess inclusions.
 
    The  Prospectus  Supplement relating  to the  Certificates  of a  Series may
provide that a Residual  Certificate may not be  purchased by or transferred  to
any  person that  is not  a U.S.  Person or  may describe  the circumstances and
restrictions pursuant  to which  such a  transfer may  be made.  The term  "U.S.
Person"  means  a  citizen or  resident  of  the United  States,  a corporation,
partnership or other entity  created or organized  in or under  the laws of  the
United  States or any political subdivision thereof,  or an estate or trust that
is subject to U.S. federal income tax regardless of the source of its income.
 
  SALE OR EXCHANGE OF A RESIDUAL CERTIFICATE
 
    Upon the sale  or exchange of  a Residual Certificate,  the Residual  Holder
will  recognize gain or loss equal to the excess, if any, of the amount realized
over the  adjusted  basis  (as  described  above  under  "Taxation  of  Residual
Certificates--Basis  and  Losses")  of  such Residual  Holder  in  such Residual
Certificate at the time of  the sale or exchange.  In addition to reporting  the
taxable  income of the REMIC Pool, a Residual Holder will have taxable income to
the extent that any cash  distribution to him from  the REMIC Pool exceeds  such
adjusted  basis on that Distribution  Date. Such income will  be treated as gain
from the sale or exchange
 
                                       79
<PAGE>
of the Residual Certificate.  It is possible that  the termination of the  REMIC
Pool  may  be treated  as a  sale or  exchange of  a Residual  Holder's Residual
Certificate, in which case, if the Residual Holder has an adjusted basis in  his
Residual  Certificate remaining when his interest  in the REMIC Pool terminates,
and if he holds such Residual Certificate as a capital asset under Code  Section
1221,  then he will recognize a capital loss  at that time in the amount of such
remaining adjusted basis.
 
    The Conference Committee  Report to the  1986 Act provides  that, except  as
provided  in Treasury regulations yet to be  issued, the wash sale rules of Code
Section 1091  will apply  to  dispositions of  Residual Certificates  where  the
seller  of  the Residual  Certificate, during  the  period beginning  six months
before the sale or disposition of the Residual Certificate and ending six months
after such sale or disposition, acquires  (or enters into any other  transaction
that  results in the application of Code  Section 1091) any residual interest in
any REMIC or  any interest in  a "taxable  mortgage pool" (such  as a  non-REMIC
owner trust) that is economically comparable to a Residual Certificate.
 
  TAXES THAT MAY BE IMPOSED ON THE REMIC POOL
 
    PROHIBITED  TRANSACTIONS.   Income  from certain  transactions by  the REMIC
Pool, called prohibited  transactions, will not  be part of  the calculation  of
income or loss includible in the federal income tax returns of Residual Holders,
but  rather will be taxed directly to the  REMIC Pool at a 100% rate. Prohibited
transactions generally include (i) the disposition of a qualified mortgage other
than for (a) substitution within  two years of the  Startup Day for a  defective
(including  a defaulted) obligation (or repurchase  in lieu of substitution of a
defective (including a defaulted) obligation at  any time) or for any  qualified
mortgage  within three months  of the Startup Day,  (b) foreclosure, default, or
imminent default of a  qualified mortgage, (c) bankruptcy  or insolvency of  the
REMIC  Pool,  or (d)  a qualified  (complete) liquidation,  (ii) the  receipt of
income from assets that are  not the type of  mortgages or investments that  the
REMIC Pool is permitted to hold, (iii) the receipt of compensation for services,
or (iv) the receipt of gain from disposition of cash flow investments other than
pursuant  to a qualified liquidation. Notwithstanding (i)  and (iv), it is not a
prohibited transaction  to sell  REMIC Pool  property to  prevent a  default  on
Regular  Certificates as  a result  of a  default on  qualified mortgages  or to
facilitate  a  clean-up  call  (generally,  an  optional  termination  to   save
administrative costs when no more than a small percentage of the Certificates is
outstanding). The Proposed REMIC Regulations indicate that the modification of a
Mortgage Loan generally will not be treated as a disposition if it is occasioned
by  a default or  reasonably foreseeable default, an  assumption of the Mortgage
Loan, the waiver of a due-on-sale clause, or the conversion of an interest  rate
by  a mortgagor pursuant to the terms  of a convertible adjustable rate Mortgage
Loan.
 
    CONTRIBUTIONS TO THE  REMIC POOL  AFTER THE STARTUP  DAY.   In general,  the
REMIC  Pool will be subject to a tax at a 100% rate on the value of any property
contributed to the REMIC Pool after the Startup Day. Exceptions are provided for
cash contributions to the REMIC Pool  (i) during the three months following  the
Startup  Day, (ii) made to a qualified  reserve fund by a Residual Holder, (iii)
in the nature of a guarantee, (iv) made to facilitate a qualified liquidation or
clean-up call, and (v) as otherwise permitted in Treasury regulations yet to  be
issued.
 
    NET  INCOME FROM FORECLOSURE  PROPERTY.  The  REMIC Pool will  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. Generally, property acquired by  deed in lieu of foreclosure
would be  treated as  "foreclosure property"  for a  period of  two years,  with
possible  extensions. Net income from  foreclosure property generally means gain
from the sale  of a foreclosure  property that is  inventory property and  gross
income   from  foreclosure  property  other  than  qualifying  rents  and  other
qualifying income for a real estate investment trust.
 
  LIQUIDATION OF THE REMIC POOL
 
    If a REMIC Pool and the Trustee adopt a plan of complete liquidation, within
the meaning of Code Section 860F(a)(4)(A)(i), and sell all of its assets  (other
than  cash) within a 90-day period beginning on  the date of the adoption of the
plan of liquidation, then the REMIC Pool  will recognize no gain or loss on  the
sale
 
                                       80
<PAGE>
of  its  assets,  provided  that  the  REMIC  Pool  credits  or  distributes  in
liquidation all of the sale proceeds plus its cash (other than amounts  retained
to  meet claims) to holders of  Regular Certificates and Residual Holders within
the 90-day period.
 
  ADMINISTRATIVE MATTERS
 
    The REMIC Pool will  be required to  maintain its books  on a calendar  year
basis  and to file federal income tax returns for federal income tax purposes in
a manner similar to a partnership. The  form for such income tax return is  Form
1066,  U.S. Real  Estate Mortgage  Investment Conduit  Income Tax  Return. Under
TAMRA, the Trustee will be required  to sign the REMIC Pool's returns.  Treasury
regulations  provide that, except where there is a single Residual Holder for an
entire taxable  year, the  REMIC Pool  will  be subject  to the  procedural  and
administrative  rules  of the  Code  applicable to  partnerships,  including the
determination by the Internal Revenue Service of any adjustments to, among other
things, items of  REMIC income, gain,  loss, deduction, or  credit in a  unified
administrative proceeding. The Servicer will be obligated to act as "tax matters
person,"  as defined  in applicable  Treasury regulations,  with respect  to the
REMIC Pool, in its capacity as either  Residual Holder or agent of the  Residual
Holders.  If  the Code  or  applicable Treasury  regulations  do not  permit the
Servicer to act as tax matters person  in its capacity as agent of the  Residual
Holders, the Residual Holder chosen by the Residual Holders or such other person
specified  pursuant  to Treasury  regulations  will be  required  to act  as tax
matters person.
 
LIMITATIONS ON DEDUCTION OF CERTAIN EXPENSES
 
    An investor  who is  an individual,  estate,  or trust  will be  subject  to
limitation with respect to certain itemized deductions described in Code Section
67, to the extent that such itemized deductions, in the aggregate, do not exceed
2%  of  the  investor's adjusted  gross  income.  In addition,  Code  Section 68
provides that itemized deductions otherwise allowable  for a taxable year of  an
individual  taxpayer will be reduced  by the lesser of (i)  3% of the excess, if
any, of adjusted gross income  over $100,000 ($50,000 in  the case of a  married
individual  filing a  separate return),  or (ii) 80%  of the  amount of itemized
deductions otherwise allowable for such year. In the case of a REMIC Pool,  such
deductions  may include deductions under Code  Section 212 for the Servicing Fee
and all administrative  and other expenses  relating to the  REMIC Pool, or  any
similar  expenses allocated to the REMIC Pool with respect to a regular interest
it holds in  another REMIC. Such  investors who hold  REMIC Certificates  either
directly  or indirectly through certain pass-through entities may have their pro
rata share of such  expenses allocated to them  as additional gross income,  but
may  be subject to such limitation on deductions. In addition, such expenses are
not deductible at all for purposes of computing the alternative minimum tax, and
may cause such investors to be subject to significant additional tax  liability.
Temporary  Treasury  regulations provide  that the  additional gross  income and
corresponding amount of expenses generally are  to be allocated entirely to  the
holders  of Residual  Certificates in the  case of  a REMIC Pool  that would not
qualify as a fixed investment trust in the absence of a REMIC election. However,
such additional gross  income and  limitation on  deductions will  apply to  the
allocable  portion of such expenses to  holders of Regular Certificates, as well
as holders of Residual Certificates, where such Regular Certificates are  issued
in  a manner that is similar to  pass-through certificates in a fixed investment
trust. In general, such allocable portion will be determined based on the  ratio
that  a REMIC Certificateholder's income, determined  on a daily basis, bears to
the income of all holders of Regular Certificates and Residual Certificates with
respect to a  REMIC Pool. As  a result, individuals,  estates or trusts  holding
REMIC  Certificates  (either directly  or  indirectly through  a  grantor trust,
partnership, S  corporation,  REMIC,  or  certain  other  pass-through  entities
described  in  the foregoing  temporary Treasury  regulations) may  have taxable
income in excess  of the  interest income at  the pass-through  rate on  Regular
Certificates  that are issued  in a single class  or otherwise consistently with
fixed investment trust status or in excess of cash distributions for the related
period on Residual Certificates.
 
TAXATION OF CERTAIN FOREIGN INVESTORS
 
  REGULAR CERTIFICATES
 
    Interest,  including  original  issue  discount,  distributable  to  Regular
Certificateholders  who are non-resident aliens,  foreign corporations, or other
Non-U.S. Persons (as defined below), will be considered
 
                                       81
<PAGE>
"portfolio interest" and, therefore, generally will not be subject to 30% United
States withholding  tax,  provided  that  such Non-U.S.  Person  (i)  is  not  a
"10-percent  shareholder" within the  meaning of Code  Section 871(h)(3)(B) or a
controlled foreign corporation described in  Code Section 881(c)(3)(C) and  (ii)
provides  the Trustee, or the person who would otherwise be required to withhold
tax from such distributions under Code Section 1441 or 1442, with an appropriate
statement, signed under penalties of  perjury, identifying the beneficial  owner
and  stating,  among other  things,  that the  beneficial  owner of  the Regular
Certificate is  a Non-U.S.  Person. If  such statement,  or any  other  required
statement,  is  not  provided,  30% withholding  will  apply  unless  reduced or
eliminated pursuant to an  applicable tax treaty or  unless the interest on  the
Regular  Certificate is  effectively connected  with the  conduct of  a trade or
business within the United States by  such Non-U.S. Person. In the latter  case,
such  Non-U.S. Person  will be  subject to United  States federal  income tax at
regular rates. Investors who are Non-U.S.  Persons should consult their own  tax
advisors  regarding the  specific tax consequences  to them of  owning a Regular
Certificate. The  term "Non-U.S.  Person" means  any person  who is  not a  U.S.
Person.
 
  RESIDUAL CERTIFICATES
 
    The  Conference Committee Report to the 1986 Act indicates that amounts paid
to Residual  Holders  who are  Non-U.S.  Persons  are treated  as  interest  for
purposes  of  the 30%  (or  lower treaty  rate)  United States  withholding tax.
Treasury regulations provide  that amounts distributed  to Residual Holders  may
qualify as "portfolio interest", subject to the conditions described in "Regular
Certificates"  above, but only  to the extent  that (i) the  Mortgage Loans were
issued after July  18, 1984  and (ii)  the Trust  Estate or  segregated pool  of
assets  therein (as to which  a separate REMIC election  will be made), to which
the Residual Certificate relates, consists of obligations issued in  "registered
form"  within the meaning  of Code Section  163(f)(1). Generally, Mortgage Loans
will not be,  but regular interests  in another REMIC  Pool will be,  considered
obligations  issued in registered form. Furthermore,  a Residual Holder will not
be entitled to any exemption from the 30% withholding tax (or lower treaty rate)
to the  extent of  that portion  of  REMIC taxable  income that  constitutes  an
"excess  inclusion."  See  "Taxation  of  Residual  Certificates--Limitations on
Offset or Exemption of  REMIC Income." If the  amounts paid to Residual  Holders
who  are Non-U.S. Persons are effectively connected  with the conduct of a trade
or business within  the United States  by such Non-U.S.  Persons, 30% (or  lower
treaty  rate)  withholding will  not apply.  Instead, the  amounts paid  to such
Non-U.S. Persons will be subject to United States federal income tax at  regular
rates.  If 30%  (or lower treaty  rate) withholding is  applicable, such amounts
generally will be taken into account for purposes of withholding only when  paid
or otherwise distributed (or when the Residual Certificate is disposed of) under
rules  similar to  withholding upon  disposition of  debt instruments  that have
original issue discount. See "Tax-Related  Restrictions on Transfer of  Residual
Certificates--Foreign  Investors"  above  concerning  the  disregard  of certain
transfers having "tax avoidance potential."  Investors who are Non-U.S.  Persons
should consult their own tax advisors regarding the specific tax consequences to
them of owning Residual Certificates.
 
BACKUP WITHHOLDING
 
    Distributions  made on the Regular Certificates,  and proceeds from the sale
of the Regular Certificates to or through  certain brokers, may be subject to  a
"backup" withholding tax under Code Section 3406 of 20% on "reportable payments"
(including  interest distributions, original issue  discount, and, under certain
circumstances, principal  distributions)  unless the  Regular  Certificateholder
complies  with certain reporting and/or  certification procedures, including the
provision of its taxpayer identification number to the Trustee, its agent or the
broker  who   effected  the   sale   of  the   Regular  Certificate,   or   such
Certificateholder  is otherwise an exempt  recipient under applicable provisions
of the  Code.  Any amounts  to  be withheld  from  distribution on  the  Regular
Certificates  would be refunded by the Internal  Revenue Service or allowed as a
credit against the Regular Certificateholder's federal income tax liability.
 
REPORTING REQUIREMENTS
 
    Reports of  accrued  interest  and  original issue  discount  will  be  made
annually to the Internal Revenue Service and to individuals, estates, non-exempt
and  non-charitable trusts, and partnerships who are either holders of record of
Regular Certificates or beneficial owners who own Regular Certificates through a
broker or middleman as nominee. All  brokers, nominees and all other  non-exempt
holders of record of Regular
 
                                       82
<PAGE>
Certificates (including corporations, non-calendar year taxpayers, securities or
commodities dealers, real estate investment trusts, investment companies, common
trust  funds,  thrift  institutions  and  charitable  trusts)  may  request such
information for any calendar  quarter by telephone or  in writing by  contacting
the  person designated in Internal Revenue  Service Publication 938 with respect
to a particular Series  of Regular Certificates.  Holders through nominees  must
request  such information  from the  nominee. Treasury  regulations provide that
information necessary  to compute  the accrual  of any  market discount  on  the
Regular Certificates must be furnished for calendar years beginning after 1990.
 
    The  Internal Revenue  Service's Form 1066  has an  accompanying Schedule Q,
Quarterly Notice to  Residual Interest Holders  of REMIC Taxable  Income or  Net
Loss  Allocation. Treasury regulations  require that Schedule  Q be furnished by
the REMIC Pool to  each Residual Holder  by the end of  the month following  the
close  of  each calendar  quarter  (41 days  after the  end  of a  quarter under
proposed Treasury regulations) in which the REMIC Pool is in existence.
 
    Treasury  regulations   require  that,   in   addition  to   the   foregoing
requirements,  information  must  be furnished  quarterly  to  Residual Holders,
furnished annually, if applicable, to holders of Regular Certificates, and filed
annually with the Internal Revenue  Service concerning Code Section 67  expenses
(see  "Limitations on  Deduction of Certain  Expenses" above)  allocable to such
holders. Furthermore,  under such  regulations,  information must  be  furnished
quarterly  to  Residual  Holders,  furnished  annually  to  holders  of  Regular
Certificates, and filed  annually with the  Internal Revenue Service  concerning
the  percentage of  the REMIC  Pool's assets  meeting the  qualified asset tests
described above under "Status of REMIC Certificates."
 
                FEDERAL INCOME TAX CONSEQUENCES FOR CERTIFICATES
                     AS TO WHICH NO REMIC ELECTION IS MADE
 
STANDARD CERTIFICATES
 
  GENERAL
 
    In the  event that  no  election is  made  to treat  a  Trust Estate  (or  a
segregated  pool  of  assets  therein)  with respect  to  a  Series  of Standard
Certificates as a REMIC, the Trust Estate will be classified as a grantor  trust
under  subpart E, Part 1 of  subchapter J of the Code  and not as an association
taxable as a corporation. Where there is no Fixed Retained Yield with respect to
the Mortgage  Loans underlying  the Certificates  of a  Series, and  where  such
Certificates  are not designated  as "Stripped Certificates"  the holder of each
such Certificate in  such Series  will be  treated as the  owner of  a pro  rata
undivided  interest  in the  ordinary income  and corpus  portions of  the Trust
Estate represented  by  his Standard  Certificate  and will  be  considered  the
beneficial owner of a pro rata undivided interest in each of the Mortgage Loans,
subject  to the discussion  below under "Recharacterization  of Servicing Fees."
Accordingly, the holder of a Standard Certificate of a particular Series will be
required to report on its  federal income tax return its  pro rata share of  the
entire  income from the Mortgage Loans  represented by his Standard Certificate,
including interest at  the coupon rate  on such Mortgage  Loans, original  issue
discount  (if any), prepayment  fees, assumption fees,  and late payment charges
received by the Servicer, in  accordance with such Standard  Certificateholder's
method  of accounting.  A Standard Certificateholder  generally will  be able to
deduct its share of the Servicing Fee and all administrative and other  expenses
of  the Trust Estate in accordance with  its method of accounting, provided that
such amounts are  reasonable compensation  for services rendered  to that  Trust
Estate.  However,  investors  who are  individuals,  estates or  trusts  who own
Standard  Certificates,   either   directly  or   indirectly   through   certain
pass-through  entities, will  be subject to  limitation with  respect to certain
itemized deductions described  in Code  Section 67,  including deductions  under
Code  Section 212 for  the Servicing Fee  and all such  administrative and other
expenses of  the  Trust Estate,  to  the extent  that  such deductions,  in  the
aggregate,  do not exceed two percent of an investor's adjusted gross income. In
addition, Code Section 68 provides that itemized deductions otherwise  allowable
for  a taxable year of  an individual taxpayer will be  reduced by the lesser of
(i) 3% of the excess, if any, of adjusted gross income over $100,000 ($50,000 in
the case of a married individual filing  a separate return), or (ii) 80% of  the
amount  of itemized deductions  otherwise allowable for such  year. As a result,
such investors holding Standard Certificates, directly or
 
                                       83
<PAGE>
indirectly through a pass-through entity,  may have aggregate taxable income  in
excess  of the aggregate  amount of cash received  on such Standard Certificates
with respect to interest at the pass-through rate or as discount income on  such
Standard  Certificates. In addition, such expenses are not deductible at all for
purposes of computing the alternative minimum tax, and may cause such  investors
to  be subject to significant additional tax liability. Moreover, where there is
Fixed Retained Yield with respect to  the Mortgage Loans underlying a Series  of
Standard  Certificates or where  the servicing fees are  in excess of reasonable
servicing compensation, the transaction  will be subject  to the application  of
the  "stripped bond" and "stripped coupon" rules of the Code, as described below
under  "Stripped  Certificates"  and  "Recharacterization  of  Servicing  Fees,"
respectively.
 
  TAX STATUS
 
    Cadwalader, Wickersham & Taft has advised the Seller that:
 
        1.    A Standard  Certificate  owned by  a  "domestic building  and loan
    association"  within  the  meaning  of  Code  Section  7701(a)(19)  will  be
    considered  to represent "loans...secured  by an interest  in real property"
    within the meaning of Code Section 7701(a)(19)(C)(v), provided that the real
    property  securing  the   Mortgage  Loans  represented   by  that   Standard
    Certificate is of the type described in such section of the Code.
 
        2.  A Standard Certificate owned by a financial institution described in
    Code  Section  593(a)  will  be  considered  to  represent  "qualifying real
    property loans" within the meaning of Code Section 593(d)(1), provided  that
    the  real property securing the Mortgage  Loans represented by that Standard
    Certificate is of the type described in such section of the Code.
 
        3.  A Standard Certificate owned by a real estate investment trust  will
    be  considered to represent "real estate  assets" within the meaning of Code
    Section 856(c)(5)(A) to  the extent  that the  assets of  the related  Trust
    Estate  consist of qualified assets, and interest income on such assets will
    be  considered  "interest  on  obligations  secured  by  mortgages  on  real
    property" within the meaning of Code Section 856(c)(3)(B).
 
        4.    A Standard  Certificate owned  by  a REMIC  will be  considered to
    represent an  "obligation (including  any  participation or  certificate  of
    beneficial ownership therein) which is principally secured by an interest in
    real  property"  within the  meaning of  Code  Section 860G(a)(3)(A)  to the
    extent that the  assets of the  related Trust Estate  consist of  "qualified
    mortgages" within the meaning of Code Section 860G(a)(3).
 
    An  issue arises as to whether Buy-Down  Loans may be characterized in their
entirety under the Code provisions cited in the immediately preceding paragraph.
Code Section 593(d)(1)(C) provides that the term "qualifying real property loan"
does not include a loan "to the extent  secured by a deposit in or share of  the
taxpayer."  The application of  this provision to a  Buy-Down Fund is uncertain,
but may require that a  taxpayer's investment in a  Buy-Down Loan be reduced  by
the  Buy-Down Fund. As  to the treatment  of Buy-Down Loans  as "qualifying real
property loans" under Code  Section 593(d)(1) if the  exception of Code  Section
593(d)(1)(C)  is  inapplicable,  as  "loans...secured  by  an  interest  in real
property" under Code  Section 7701(a)(19)(C)(v), as  "real estate assets"  under
Code Section 856(c)(5)(A), and as "obligation[s] . . . principally secured by an
interest  in real property" under Code  Section 860G(a)(3)(A), there is indirect
authority supporting treatment of an investment  in a Buy-Down Loan as  entirely
secured  by real property if the fair market value of the real property securing
the loan exceeds the  principal amount of  the loan at the  time of issuance  or
acquisition,  as  the case  may be.  There  is no  assurance that  the treatment
described above is proper. Accordingly, Standard Certificateholders are urged to
consult their own tax  advisors concerning the effects  of such arrangements  on
the characterization of such Standard Certificateholder's investment for federal
income tax purposes.
 
                                       84

  PREMIUM AND DISCOUNT
 
    Standard  Certificateholders are advised to  consult with their tax advisors
as to the federal  income tax treatment of  premium and discount arising  either
upon initial acquisition of Standard Certificates or thereafter.
 
    PREMIUM.   The treatment of premium incurred upon the purchase of a Standard
Certificate will  be  determined generally  as  described above  under  "Federal
Income   Tax   Consequences   for  REMIC   Certificates--Taxation   of  Residual
Certificates--Premium."
 
    ORIGINAL ISSUE  DISCOUNT.    The  Internal Revenue  Service  has  stated  in
published  rulings that, in circumstances similar to those described herein, the
original   issue   discount   rules   will   be   applicable   to   a   Standard
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 income  are  applicable to  mortgages of
corporations originated after May 27, 1969, mortgages of noncorporate mortgagors
(other than  individuals)  originated  after  July 1,  1982,  and  mortgages  of
individuals  originated after March 2, 1984.  Such original issue discount could
arise by the charging of points by the originator of the mortgages in an  amount
greater than a statutory DE MINIMIS exception, to the extent that the points are
not  currently  deductible  under  applicable Code  provisions  or  are  not for
services provided by the lender. It is generally not anticipated that adjustable
rate Mortgage Loans  will be  treated as  issued with  original issue  discount.
However, the application of the Proposed Regulations to adjustable rate mortgage
loans  with incentive interest rates or annual or lifetime interest rate caps is
unclear and may result in original issue discount if not further clarified.
 
    Original issue discount must generally be reported as ordinary gross  income
as  it accrues  under a  constant interest  method that  takes into  account the
compounding of interest,  in advance of  the cash attributable  to such  income.
However,  Code Section 1272 provides  for a reduction in  the amount of original
issue discount  includible in  the income  of  a holder  of an  obligation  that
acquires  the obligation 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 Standard Certificateholder are  purchased at a price equal to  the
then  unpaid principal amount of such Mortgage Loans, no original issue discount
attributable to  the  difference  between  the  issue  price  and  the  original
principal  amount of  such Mortgage Loans  (I.E., points) will  be includible by
such holder.
 
    MARKET DISCOUNT.  Standard  Certificateholders also will  be subject to  the
market discount rules to the extent that the conditions for application of those
sections  are met. Market discount on the  Mortgage Loans will be determined and
will be reported  as ordinary  income generally  in the  manner described  above
under  "Federal  Income  Tax Consequences  for  REMIC  Certificates--Taxation of
Residual Certificates--Market Discount."
 
    RECHARACTERIZATION OF SERVICING  FEES.  If  the servicing fees  paid to  the
Servicer  were deemed to exceed reasonable servicing compensation, the amount of
such excess  would be  nondeductible under  Code  Section 162  or 212.  In  this
regard, there are no authoritative guidelines for federal income tax purposes as
to  either the maximum  amount of servicing compensation  that may be considered
reasonable in the  context of this  or similar transactions  or whether, in  the
case  of the Standard Certificate,  the reasonableness of servicing compensation
should be determined on a weighted average or loan-by-loan basis. If a  loan-by-
loan  basis  is  appropriate,  the  likelihood  that  such  amount  would exceed
reasonable servicing compensation  as to  some of  the Mortgage  Loans would  be
increased.  Recently issued Internal  Revenue Service guidance  indicates that a
servicing fee in  excess of  reasonable compensation  ("excess servicing")  will
cause  the Mortgage Loans  to be treated  under the "stripped  bond" rules. Such
guidance provides  safe  harbors  for  servicing deemed  to  be  reasonable  and
requires  taxpayers to demonstrate that the value of servicing fees in excess of
such amounts is not greater than the value of the services provided.
 
    Accordingly, if  the  Internal  Revenue  Service's  approach  is  upheld,  a
Servicer  who receives a servicing fee in excess of such amounts would be viewed
as  retaining   an   ownership  interest   in   a  portion   of   the   interest
 
                                       85
<PAGE>
payments  on  the Mortgage  Loans. Under  the  rules of  Code Section  1286, the
separation of ownership  of the right  to receive  some or all  of the  interest
payments on an obligation from the right to receive some or all of the principal
payments  on the obligation would result in  treatment of such Mortgage Loans as
"stripped coupons" and "stripped bonds."  Each stripped bond or stripped  coupon
could be considered for this purpose as a non-interest bearing obligation issued
on  the  date of  issue of  the  Standard Certificates,  and the  original issue
discount rules of  the Code would  apply to the  holder thereof. While  Standard
Certificateholders would still be treated as owners of beneficial interests in a
grantor trust for federal income tax purposes, the corpus of such trust could be
viewed  as excluding the portion of the Mortgage Loans the ownership of which is
attributed to the Servicer, or  as including such portion  as a second class  of
equitable interest. Applicable Treasury regulations treat such an arrangement as
a  fixed investment trust, since the  multiple classes of trust interests should
be treated as merely facilitating direct investments in the trust assets and the
existence of  multiple classes  of  ownership interests  is incidental  to  that
purpose.  In general, such a recharacterization  should not have any significant
effect  upon  the   timing  or  amount   of  income  reported   by  a   Standard
Certificateholder,  except that the income reported  by a cash method holder may
be slightly  accelerated.  See  "Stripped  Certificates"  below  for  a  further
description  of the federal income tax  treatment of stripped bonds and stripped
coupons.
 
    In the alternative, the amount, if any, by which the servicing fees paid  to
the Servicer are deemed to exceed reasonable compensation for servicing could be
treated   as   deferred   payments   of   purchase   price   by   the   Standard
Certificateholders to  the Seller  to  purchase its  undivided interest  in  the
Mortgage  Loans. In  such event, the  present value of  such additional payments
might be included in  the Standard Certificateholder's  basis in such  undivided
interests  for  purposes of  determining  whether the  Standard  Certificate was
acquired at  a  discount, at  par,  or at  a  premium. Under  this  alternative,
Standard  Certificateholders may  also be entitled  to a  deduction for unstated
interest with respect to each deferred payment. The Internal Revenue Service may
take the position that  the specific statutory provisions  of Code Section  1286
described  above override the alternative  described in this paragraph. Standard
Certificateholders are advised to  consult their tax advisors  as to the  proper
treatment  of the amounts paid to the  Servicer as set forth herein as servicing
compensation or under either of the alternatives set forth above.
 
  SALE OR EXCHANGE OF STANDARD CERTIFICATES
 
    Upon  sale   or   exchange   of   a   Standard   Certificate,   a   Standard
Certificateholder  will recognize gain  or loss equal  to the difference between
the amount realized on the sale and its aggregate adjusted basis in the Mortgage
Loans and other assets represented by the Standard Certificate. In general,  the
aggregate  adjusted basis will  equal the Standard  Certificateholder's cost for
the Standard  Certificate, increased  by  the amount  of any  income  previously
reported with respect to the Standard Certificate and decreased by the amount of
any  losses previously reported with respect to the Standard Certificate and the
amount of  any distributions  received thereon.  Except as  provided above  with
respect  to  market  discount on  any  Mortgage  Loans, and  except  for certain
financial institutions subject  to the  provisions of Code  Section 582(c),  any
such  gain or loss would be capital gain or loss if the Standard Certificate was
held as a capital asset. The preferential rates applicable to long-term  capital
gains  were eliminated by the  Tax Reform Act of 1986,  but were restored by the
Revenue Reconciliation Act of 1990 with respect to certain individuals.
 
STRIPPED CERTIFICATES
 
  GENERAL
 
    Pursuant to Code Section 1286, the  separation of ownership of the right  to
receive some or all of the principal payments on an obligation from ownership of
the  right  to receive  some  or all  of the  interest  payments results  in the
creation of "stripped bonds"  with respect to  principal payments and  "stripped
coupons"  with respect  to interest payments.  For purposes  of this discussion,
Certificates that are subject  to those rules will  be referred to as  "Stripped
Certificates." The Certificates will be subject to those rules if (i) the Seller
or  any  of its  affiliates  retains (for  its own  account  or for  purposes of
resale), in the form of Fixed Retained Yield or otherwise, an ownership interest
in a portion of the  payments on the Mortgage Loans,  (ii) the Seller or any  of
its  affiliates is treated as having an ownership interest in the Mortgage Loans
to the
 
                                       86
<PAGE>
extent it is paid (or retains) servicing compensation in an amount greater  than
reasonable  consideration  for  servicing  the  Mortgage  Loans  (see  "Standard
Certificates--Recharacterization of  the Servicing  Fees"  above), and  (iii)  a
Class  of  Certificates  are  issued  in  two  or  more  Classes  or  Subclasses
representing the right to non-pro-rata percentages of the interest and principal
payments on the Mortgage Loans.
 
    In general, a  holder of a  Stripped Certificate will  be considered to  own
"stripped  bonds" with respect to its pro rata  share of all or a portion of the
principal payments on each Mortgage Loan and/or "stripped coupons" with  respect
to  its pro  rata share of  all or  a portion of  the interest  payments on each
Mortgage Loan,  including  the Stripped  Certificate's  allocable share  of  the
servicing  fees paid  to the  Servicer, to the  extent that  such fees represent
reasonable compensation  for  services  rendered.  See  discussion  above  under
"Standard  Certificates--Recharacterization of Servicing Fees." For this purpose
the servicing fees will be allocated to the Stripped Certificates in  proportion
to  the  respective  offering price  of  each  Class (or  Subclass)  of Stripped
Certificates. The holder of a Stripped Certificate generally will be entitled to
a deduction each year in respect of the servicing fees, as described above under
"Standard Certificates-- General," subject to the limitation described therein.
 
    Code Section 1286 treats a stripped  bond or a stripped coupon generally  as
an  obligation  issued at  an  original issue  discount  on the  date  that such
stripped interest is purchased. Although the treatment of Stripped  Certificates
for  federal income tax purposes is not  clear in certain respects at this time,
particularly where  such Stripped  Certificates  are issued  with respect  to  a
Mortgage  Pool  containing variable-rate  Mortgage  Loans, the  Seller  has been
advised by counsel that (i) the Trust Estate will be treated as a grantor  trust
under  subpart E, Part I of  subchapter J of the Code  and not as an association
taxable as a corporation, and (ii)  each Stripped Certificate should be  treated
as  a single installment  obligation for purposes  of calculating original issue
discount and  gain  or loss  on  disposition. This  treatment  is based  on  the
interrelationship of Code Section 1286, Code Sections 1272 through 1275, and the
Proposed  OID  Regulations.  While  under Code  Section  1286  computations with
respect to Stripped  Certificates arguably  should be made  in one  of the  ways
described  below under "Taxation  of Stripped Certificates--Possible Alternative
Characterizations," the Proposed  OID Regulations  state, in  general, that  all
debt  instruments issued in connection with the same transaction must be treated
as a single debt instrument. The  Pooling and Servicing Agreement requires  that
the  Trustee  make  and  report  all  computations  described  below  using this
aggregate approach, unless substantial legal authority requires otherwise.
 
    Furthermore, proposed Treasury regulations issued August 8, 1991 support the
treatment of a Stripped  Certificate as a single  debt instrument issued on  the
date  it is originated for purposes  of calculating any original issue discount.
In addition,  under  these proposed  regulations,  a Stripped  Certificate  that
represents  a right  to payments  of both interest  and principal  may be viewed
either as issued with original issue  discount or market discount (as  described
below),  at a DE MINIMIS original issue  discount, or, presumably, at a premium.
This  treatment  suggests  that  the  interest  component  of  such  a  Stripped
Certificate  would be treated as qualified  periodic interest under the Proposed
OID Regulations. Further, the August 1991 proposed regulations provide that  the
purchaser  of such a  Stripped Certificate will  be required to  account for any
discount as market discount  rather than original issue  discount if either  (i)
the  initial discount  with respect to  the Stripped Certificate  was treated as
zero under the DE MINIMIS rule, or (ii) no more than 100 basis points in  excess
of  reasonable servicing  is stripped off  the related Mortgage  Loans. Any such
market discount would be reportable as described above under "Federal Income Tax
Consequences for  REMIC Certificates--Taxation  of Regular  Certificates--Market
Discount,"  without regard to  the DE MINIMIS rule  therein. Pursuant to Revenue
Procedure 91-49, issued August 8, 1991,  investors using a method of  accounting
inconsistent with the above treatment must change their method of accounting and
request  the  consent  to the  Internal  Revenue  Service to  such  change  on a
statement attached to  their first timely  federal income tax  returned for  the
first tax year ending after August 8, 1991.
 
  STATUS OF STRIPPED CERTIFICATES
 
    No  specific  legal authority  exists  as to  whether  the character  of the
Stripped Certificates, for federal income tax purposes, will be the same as that
of   the   Mortgage   Loans.   Although    the   issue   is   not   free    from
 
                                       87
<PAGE>
doubt,  counsel  has  advised the  Seller  that Stripped  Certificates  owned by
applicable holders should be considered  to represent "qualifying real  property
loans" within the meaning of Code Section 593(d)(1), "real estate assets" within
the  meaning  of Code  Section 856(c)(5)(A),  "obligation[s]  . .  . principally
secured by an  interest in  real property" within  the meaning  of Code  Section
860G(a)(3)(A),  and "loans...secured by an interest in real property" within the
meaning of  Code Section  7701(a)(19)(C)(v),  and interest  (including  original
issue   discount)  income  attributable  to   Stripped  Certificates  should  be
considered to represent "interest  on obligations secured  by mortgages on  real
property" within the meaning of Code Section 856(c)(3)(B), provided that in each
case  the Mortgage Loans  and interest on  such Mortgage Loans  qualify for such
treatment. The  application  of  such  Code  provisions  to  Buy-Down  Loans  is
uncertain. See "Standard Certificates--Tax Status" above.
 
  TAXATION OF STRIPPED CERTIFICATES
 
    ORIGINAL  ISSUE DISCOUNT.   Except as described  above under "General," each
Stripped Certificate will be considered to have been issued at an original issue
discount for federal income tax  purposes. Original issue discount with  respect
to  a Stripped Certificate must be included in ordinary income as it accrues, in
accordance  with  a  constant  interest  method  that  takes  into  account  the
compounding  of  interest,  which  may  be prior  to  the  receipt  of  the cash
attributable to such income. Based in  part on the Proposed OID Regulations  and
the  amendments to the original issue discount  sections of the Code made by the
1986 Act,  counsel has  advised the  Seller that  the amount  of original  issue
discount  required  to be  included  in the  income of  a  holder of  a Stripped
Certificate (referred to in this  discussion as a "Stripped  Certificateholder")
in  any taxable year likely will be  computed generally as described above under
"Federal Income  Tax Consequences  for REMIC  Certificates--Taxation of  Regular
Certificates--Original Issue Discount" and
"--Variable  Rate Regular Certificates." However, with the apparent exception of
a Stripped  Certificate  issued  with  DE MINIMIS  original  issue  discount  as
described  above under "General," the issue price of a Stripped Certificate will
be the purchase  price paid by  each holder thereof,  and the stated  redemption
price  at maturity will include the aggregate  amount of the payments to be made
on the Stripped Certificate to such Stripped Certificateholder, presumably under
the Prepayment Assumption.
 
    If the Mortgage Loans  prepay at a  rate either faster  or slower than  that
under  the Prepayment Assumption, a  Stripped Certificateholder's recognition of
original issue discount will be either accelerated or decelerated and the amount
of such original issue discount will be either increased or decreased  depending
on  the  relative interests  in  principal and  interest  on each  Mortgage Loan
represented by such Stripped Certificateholder's Stripped Certificate. While the
matter is not free from  doubt, the holder of  a Stripped Certificate should  be
entitled  in the year that it  becomes certain (assuming no further prepayments)
that the  holder will  not  recover a  portion of  its  adjusted basis  in  such
Stripped  Certificate to  recognize an  ordinary loss  equal to  such portion of
unrecoverable basis.
 
    As an alternative to the method described  above, the fact that some or  all
of  the interest payments with respect to  the Stripped Certificates will not be
made if the  Mortgage Loans are  prepaid could lead  to the interpretation  that
such  interest payments are "contingent" within  the meaning of the Proposed OID
Regulations. If the rules of the Proposed OID Regulations relating to contingent
payments apply, treatment of a Stripped Certificate under such rules depends  on
whether  the aggregate amount of  principal payments, if any,  to be made on the
Stripped Certificate  is less  than or  greater  than its  issue price.  If  the
aggregate  principal payments are greater than or  equal to the issue price, the
principal payments would be treated as a separate installment obligation  issued
at  a price equal  to the purchase  price for the  Stripped Certificate. In such
case, original issue discount would be  calculated and accrued under the  method
described  above without consideration of the  interest payments with respect to
the Stripped Certificate. Such payments of  interest would be includible in  the
Stripped  Certificateholder's  gross income  in the  taxable  year in  which the
amounts become fixed. If the aggregate  amount of principal payments to be  made
on  the  Stripped Certificate  is less  than  its issue  price, each  payment of
principal would be treated as a return of basis. Each payment of interest  would
be treated as includible in gross income to the extent of the applicable Federal
rate  under  Code Section  1274(d),  as applied  to  the adjusted  basis  of the
Stripped Certificate, while amounts
 
                                       88
<PAGE>
received in excess of  the applicable Federal rate,  as applied to the  adjusted
basis  of the Stripped Certificate, would be  characterized as a return of basis
until the  total  amount of  interest  payments treated  as  a return  of  basis
equalled  the excess of  the purchase price over  the aggregate stated principal
payments. Any  additional  interest  payments thereafter  would  be  treated  as
ordinary income. While not free from doubt, counsel for the Seller believes that
uncertainty as to the payment of interest arising as a result of the possibility
of  prepayment of  the Mortgage  Loans should  not cause  the contingent payment
rules under the Proposed  OID Regulations to apply  to interest with respect  to
the Stripped Certificates.
 
    SALE  OR EXCHANGE OF STRIPPED CERTIFICATES.   Sale or exchange of a Stripped
Certificate prior to  its maturity  will result  in gain  or loss  equal to  the
difference,   if   any,   between   the  amount   received   and   the  Stripped
Certificateholder's adjusted basis  in such Stripped  Certificate, as  described
above under "Federal Income Tax Consequences for REMIC Certificates--Taxation of
Regular  Certificates--Sale or Exchange of  Regular Certificates." To the extent
that a  subsequent  purchaser's purchase  price  is exceeded  by  the  remaining
payments  on  the  Stripped  Certificates,  such  subsequent  purchaser  will be
required for federal income tax purposes to accrue and report such excess as  if
it  were original issue discount in the  manner described above. It is not clear
for this purpose whether the assumed prepayment  rate that is to be used in  the
case   of  a  Stripped   Certificateholder  other  than   an  original  Stripped
Certificateholder should be the Prepayment Assumption or a new rate based on the
circumstances at the date of subsequent purchase.
 
    PURCHASE OF MORE THAN ONE CLASS OF STRIPPED CERTIFICATES.  Where an investor
purchases more than one Class of Stripped Certificates, it is currently  unclear
whether  for federal income  tax purposes such  Classes of Stripped Certificates
should be treated separately or aggregated  for purposes of the rules  described
above.
 
    POSSIBLE  ALTERNATIVE  CHARACTERIZATIONS.    The  characterizations  of  the
Stripped Certificates discussed above are not the only possible  interpretations
of  the applicable Code provisions.  For example, the Stripped Certificateholder
may be treated as the owner of (i) one installment obligation consisting of such
Stripped Certificate's pro rata share of the payments attributable to  principal
on  each Mortgage  Loan and a  second installment obligation  consisting of such
Stripped Certificate's pro rata share  of the payments attributable to  interest
on  each Mortgage Loan, (ii) as many stripped bonds or stripped coupons as there
are scheduled payments of  principal and/or interest on  each Mortgage Loan,  or
(iii) a separate installment obligation for each Mortgage Loan, representing the
Stripped  Certificate's pro rata share of  payments of principal and/or interest
to be  made with  respect thereto.  Alternatively,  the holder  of one  or  more
Classes  of Stripped  Certificates may  be treated  as the  owner of  a pro rata
fractional undivided interest  in each  Mortgage Loan  to the  extent that  such
Stripped  Certificate,  or Classes  of Stripped  Certificates in  the aggregate,
represent the  same pro  rata portion  of principal  and interest  on each  such
Mortgage  Loan, and  a stripped bond  or stripped  coupon (as the  case may be),
treated as an installment obligation or contingent payment obligation, as to the
remainder.
 
    Because of these possible varying characterizations of Stripped Certificates
and  the  resultant   differing  treatment  of   income  recognition,   Stripped
Certificateholders  are urged  to consult their  own tax  advisors regarding the
proper treatment of Stripped Certificates for federal income tax purposes.
 
REPORTING REQUIREMENTS AND BACKUP WITHHOLDING
 
    The Trustee will  furnish, within a  reasonable time after  the end of  each
calendar  year, to each Standard Certificateholder or Stripped Certificateholder
at any time during such year, such information (prepared on the basis  described
above)  as  the  Trustee deems  to  be  necessary or  desirable  to  enable such
Certificateholders to prepare their federal income tax returns. Such information
will include the amount of original issue discount accrued on Certificates  held
by   persons  other   than  Certificateholders   exempted  from   the  reporting
requirements. The amount required to be reported by the Trustee may not be equal
to the  proper amount  of original  issue discount  required to  be reported  as
taxable income by a Certificateholder, other than an original Certificateholder.
The  Trustee will  also file such  original issue discount  information with the
Internal Revenue Service.  If a  Certificateholder fails to  supply an  accurate
taxpayer  identification number or  if the Secretary  of the Treasury determines
that  a  Certificateholder   has  not   reported  all   interest  and   dividend

income  required  to be  shown  on his  federal  income tax  return,  20% backup
withholding may be required in respect of any reportable payments, as  described
above  under  "Federal Income  Tax  Consequences for  REMIC Certificates--Backup
Withholding."
 
TAXATION OF CERTAIN FOREIGN INVESTORS
 
    To the extent that a Standard Certificate or Stripped Certificate  evidences
ownership in Mortgage Loans that are issued on or before July 18, 1984, interest
or  original issue discount  paid by the  person required to  withhold tax under
Code Section 1441 or 1442 to nonresident aliens, foreign corporations, or  other
non-U.S.  persons ("foreign  persons") generally will  be subject  to 30% United
States withholding tax, or such lower rate as may be provided for interest by an
applicable tax  treaty.  Accrued  original  issue  discount  recognized  by  the
Standard Certificateholder or Stripped Certificateholder on the sale or exchange
of  such a Certificate  also will be subject  to federal income  tax at the same
rate.
 
    Treasury regulations provide that interest  or original issue discount  paid
by  the  Trustee  or other  withholding  agent  to a  foreign  person evidencing
ownership interest  in  Mortgage  Loans  issued after  July  18,  1984  will  be
"portfolio interest" and will be treated in the manner, and such persons will be
subject  to the same  certification requirements described  above under "Federal
Income Tax  Consequences for  REMIC  Certificates--Taxation of  Certain  Foreign
Investors--Regular Certificates."
 
                              ERISA CONSIDERATIONS
 
GENERAL
 
    The  Employee Retirement Income Security Act  of 1974, as amended ("ERISA"),
imposes certain requirements on those employee benefit plans to which it applies
("Plans") and on those persons who  are fiduciaries with respect to such  Plans.
The  following  is  a  general  discussion  of  such  requirements,  and certain
applicable exceptions to and  administrative exemptions from such  requirements.
For  purposes of this discussion, a person  investing on behalf of an individual
retirement account established under Code Section 408 (an "IRA") is regarded  as
a fiduciary and the IRA as a Plan.
 
    Before purchasing any Certificates, a Plan fiduciary should consult with its
counsel  and determine  whether there  exists any  prohibition to  such purchase
under the requirements of ERISA, whether prohibited transaction exemptions  such
as  PTE 83-1  or any  individual administrative  exemption (as  described below)
applies, including whether the appropriate conditions set forth therein would be
met, or whether  any statutory prohibited  transaction exemption is  applicable,
and further should consult the applicable Prospectus Supplement relating to such
Series of Certificates.
 
CERTAIN REQUIREMENTS UNDER ERISA
 
    GENERAL.   In  accordance with  ERISA's general  fiduciary standards, before
investing in a Certificate a Plan fiduciary should determine whether to do so is
permitted under the governing Plan instruments  and is appropriate for the  Plan
in view of its overall investment policy and the composition and diversification
of  its  portfolio.  A  Plan  fiduciary  should  especially  consider  the ERISA
requirement of investment  prudence and  the sensitivity  of the  return on  the
Certificates  to the rate of principal repayments (including prepayments) on the
Mortgage Loans, as discussed in "Prepayment and Yield Considerations" herein.
 
    PARTIES IN INTEREST/DISQUALIFIED  PERSONS.  Other  provisions of ERISA  (and
corresponding  provisions of  the Code) prohibit  certain transactions involving
the assets of a Plan and persons who have certain specified relationships to the
Plan  (so-called  "parties  in  interest"   within  the  meaning  of  ERISA   or
"disqualified persons" within the meaning of the Code). The Seller, the Servicer
or the Trustee or certain affiliates thereof might be considered or might become
"parties  in interest" or "disqualified persons" with  respect to a Plan. If so,
the acquisition or holding of Certificates by or on behalf of such Plan could be
considered to give  rise to  a "prohibited  transaction" within  the meaning  of
ERISA  and the Code  unless an administrative exemption  described below or some
other exemption is available.
 
                                       90
<PAGE>
    Special caution should be exercised before the assets of a Plan are used  to
purchase a Certificate if, with respect to such assets, the Seller, the Servicer
or  the Trustee  or an affiliate  thereof either: (a)  has investment discretion
with respect to the investment of such assets of such Plan; or (b) has authority
or responsibility to give, or regularly gives, investment advice with respect to
such assets for a fee  and pursuant to an  agreement or understanding that  such
advice  will serve as a  primary basis for investment  decisions with respect to
such assets and  that such  advice will be  based on  the particular  investment
needs of the Plan.
 
    DELEGATION  OF FIDUCIARY DUTY.   Further, if the assets  included in a Trust
Estate were  deemed to  constitute Plan  assets, it  is possible  that a  Plan's
investment in the Certificates might be deemed to constitute a delegation, under
ERISA,  of the duty to manage Plan assets by the fiduciary deciding to invest in
the Certificates,  and certain  transactions involved  in the  operation of  the
Trust  Estate might be deemed to  constitute prohibited transactions under ERISA
and the Code. Neither ERISA nor the Code define the term "plan assets."
 
    The U.S. Department of Labor (the "Department") has issued regulations  (the
"Regulations")  concerning whether  or not  a Plan's  assets would  be deemed to
include an interest  in the  underlying assets  of an  entity (such  as a  Trust
Estate)  for  purposes of  the reporting  and  disclosure and  general fiduciary
responsibility provisions of ERISA,  as well as  for the prohibited  transaction
provisions  of ERISA  and the  Code, if the  Plan acquires  an "equity interest"
(such as a Certificate) in such an entity.
 
    Certain exceptions  are provided  in the  Regulations whereby  an  investing
Plan's assets would be deemed merely to include its interest in the Certificates
instead  of being deemed to include an interest in the assets of a Trust Estate.
However, it  cannot be  predicted in  advance nor  can there  be any  continuing
assurance  whether such exceptions may be met,  because of the factual nature of
certain of the  rules set  forth in  the Regulations.  For example,  one of  the
exceptions  in the  Regulations states that  the underlying assets  of an entity
will not  be considered  "plan assets"  if less  than 25%  of the  value of  all
classes  of equity  interests are  held by  "benefit plan  investors," which are
defined as Plans,  IRAs, and employee  benefit plans not  subject to ERISA  (for
example,  governmental plans),  but this  exception is  tested immediately after
each acquisition  of an  equity  interest in  the  entity whether  upon  initial
issuance or in the secondary market.
 
ADMINISTRATIVE EXEMPTIONS
 
    INDIVIDUAL    ADMINISTRATIVE   EXEMPTIONS.       Several   underwriters   of
mortgage-backed securities  have  applied  for  and  obtained  ERISA  prohibited
transaction  exemptions (each, an  "Underwriter's Exemption") which  are in some
respects broader  than Prohibited  Transaction Class  Exemption 83-1  (described
below).  Such  exemptions can  only apply  to mortgage-backed  securities which,
among other  conditions, are  sold in  an offering  with respect  to which  such
underwriter  serves as the  sole or a  managing underwriter, or  as a selling or
placement agent. If  such an Underwriter's  Exemption might be  applicable to  a
Series  of Certificates,  the related Prospectus  Supplement will  refer to such
possibility.
 
    Among the conditions that must  be satisfied for an Underwriter's  Exemption
to apply are the following:
 
        (1) The acquisition of 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 interests  evidenced by Certificates acquired by  the
    Plan  are not  subordinated to the  rights and interests  evidenced by other
    Certificates of the Trust Estate;
 
        (3) The Certificates acquired by the Plan have received a rating at  the
    time  of such acquisition  that is one  of the three  highest generic rating
    categories  from  either  Standard  &  Poors  Corporation  ("S&P"),  Moody's
    Investors  Service, Inc.  ("Moody's"), Duff &  Phelps Rating  Co. ("D&P") or
    Fitch Investors Service, Inc. ("Fitch");
 
                                       91
<PAGE>
        (4) The Trustee  must not be  an affiliate  of any other  member of  the
    Restricted Group (as defined below);
 
        (5)  The sum of all payments made  to and retained by the underwriter in
    connection with the  distribution of 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  Mortgage Loans to  the Trust Estate  represents not more  than the fair
    market value of such  Mortgage 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 Pooling  and
    Servicing  Agreement and reimbursement 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.
 
    The Trust Estate must also meet the following requirements:
 
            (i) the assets of the Trust Estate must consist solely of assets  of
       the  type  that  have been  included  in  other investment  pools  in the
       marketplace;
 
           (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 the
       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 the Certificates.
 
    If  the conditions to an  Underwriter's Exemption are met,  whether or not a
Plan's assets would be deemed to  include an ownership interest in the  Mortgage
Loans   in  a  mortgage  pool,  the  acquisition,  holding  and  resale  of  the
Certificates by Plans would be exempt from the prohibited transaction provisions
of ERISA and the Code.
 
    Moreover,  an  Underwriter's  Exemption  can  provide  relief  from  certain
self-dealing/conflict  of interest prohibited  transactions that may  occur if a
Plan fiduciary causes a Plan to acquire Certificates in a Trust Estate in  which
the fiduciary (or its affiliate) is an obligor on the Mortgage Loans held in the
Trust  Estate provided  that, among  other requirements: (i)  in the  case of an
acquisition in connection with  the initial issuance  of Certificates, at  least
fifty  percent of  each class  of Certificates in  which Plans  have invested is
acquired by  persons independent  of the  Restricted Group  and at  least  fifty
percent  of the aggregate  interest in the  Trust Estate is  acquired by persons
independent of the Restricted Group (as defined below); (ii) such fiduciary  (or
its  affiliate) is an obligor  with respect to five percent  or less of the fair
market value of  the Mortgage  Loans contained in  the Trust  Estate; (iii)  the
Plan's  investment  in Certificates  of any  Class  does not  exceed twenty-five
percent 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 of  the assets  of the  Plan  with respect  to which  such person  is  a
fiduciary  are invested in Certificates representing  an interest in one or more
trusts containing assets sold or served by the same entity.
 
    An Underwriter's Exemption does not apply to Plans sponsored by the  Seller,
the  underwriter specified in the applicable Prospectus Supplement, the Trustee,
the Servicer, any obligor with respect  to Mortgage Loans included in the  Trust
Estate  constituting  more  than  five  percent  of  the  aggregate  unamortized
principal balance of the assets  in the Trust Estate,  or any affiliate of  such
parties (the "Restricted Group").
 
    PTE   83-1.    Prohibited  Transaction  Class  Exemption  83-1  for  Certain
Transactions Involving  Mortgage Pool  Investment  Trusts ("PTE  83-1")  permits
certain  transactions  involving the  creation,  maintenance and  termination of
certain residential mortgage pools  and the acquisition  and holding of  certain
residential
 
                                       92
<PAGE>
mortgage  pool pass-through  certificates by  Plans, whether  or not  the Plan's
assets would be deemed to include an ownership interest in the mortgages in such
mortgage pools,  and  whether  or  not  such  transactions  would  otherwise  be
prohibited under ERISA.
 
    The  term "mortgage pool pass-through certificate" is defined in PTE 83-1 as
"a certificate  representing a  beneficial undivided  fractional interest  in  a
mortgage  pool and  entitling the holder  of such a  certificate to pass-through
payment of principal and interest from the pooled mortgage loans, less any  fees
retained  by the pool sponsor."  It appears that, for  purposes of PTE 83-1, the
term "mortgage pool pass-through certificate" would include Certificates  issued
in  a single Class or in multiple Classes that evidence the beneficial ownership
of both  a specified  percentage of  future interest  payments (after  permitted
deductions)  and a specified percentage of  future principal payments on a Trust
Estate.
 
    However, it appears that PTE  83-1 does or might  not apply to the  purchase
and holding of (a) Certificates that evidence the beneficial ownership only of a
specified percentage of future interest payments (after permitted deductions) on
a Trust Estate or only of a specified percentage of future principal payments on
a Trust Estate, (b) Residual Certificates, (c) Certificates evidencing ownership
interests in a Trust Estate which includes Mortgage Loans secured by multifamily
residential  properties or shares issued by cooperative housing corporations, or
(d) Certificates which are subordinated to other Classes of Certificates of such
Series. Accordingly, unless exemptive relief other than PTE 83-1 applies,  Plans
should not purchase any such Certificates.
 
    PTE  83-1 sets forth  "general conditions" and  "specific conditions" to its
applicability.  Section  II  of  PTE  83-1  sets  forth  the  following  general
conditions  to the application of the exemption: (i) the maintenance of a system
of insurance or other protection for  the pooled mortgage loans or the  property
securing  such loans, and for indemnifying certificateholders against reductions
in pass-through payments due  to property damage or  defaults in loan  payments;
(ii)  the  existence of  a pool  trustee who  is  not an  affiliate of  the pool
sponsor; and  (iii) a  requirement that  the sum  of all  payments made  to  and
retained  by the pool sponsor, and all funds  inuring to the benefit of the pool
sponsor as a result of the  administration of the mortgage pool, must  represent
not  more  than  adequate  consideration for  selling  the  mortgage  loans plus
reasonable compensation for services provided by  the pool sponsor to the  pool.
The  system of  insurance or  protection referred  to in  clause (i)  above must
provide such protection and  indemnification up to an  amount not less than  the
greater  of one percent of the aggregate  unpaid principal balance of the pooled
mortgages or the unpaid principal balance  of the largest mortgage in the  pool.
It  should be noted that in promulgating PTE 83-1 (and a predecessor exemption),
the Department did not  have under its consideration  interests in pools of  the
exact nature as some of the Certificates described herein.
 
EXEMPT PLANS
 
    Employee  benefit plans which are governmental  plans (as defined in Section
3(32) of ERISA), and certain church plans (as defined in Section 3(33) of ERISA)
are not subject to ERISA requirements and  assets of such plans may be  invested
in  Certificates without regard to the  ERISA considerations described above but
such plans may  be subject  to the provisions  of other  applicable federal  and
state law.
 
UNRELATED BUSINESS TAXABLE INCOME--RESIDUAL CERTIFICATES
 
    The  purchase  of  a  Residual  Certificate  by  any  employee  benefit plan
qualified under Code Section 401(a) and exempt from taxation under Code  Section
501(a),  including most  varieties of ERISA  Plans, may give  rise to "unrelated
business taxable  income"  as  described  in Code  Sections  511-515  and  860E.
Further,   prior  to  the  purchase  of  Residual  Certificates,  a  prospective
transferee may be required to  provide an affidavit to  a transferor that it  is
not,  nor is it purchasing a Residual  Certificate on behalf of, a "Disqualified
Organization," which term as defined above includes certain tax-exempt  entities
not subject to Code Section 511 such as certain governmental plans, as discussed
above under the caption "Certain Federal Income Tax Consequences--Federal Income
Tax Consequences for REMIC Certificates--Taxation of Residual
Certificates--Tax-elated Restrictions on Transfer of Residual
Certificates--isqualified Organizations."
 
                                       93
<PAGE>
    DUE  TO THE COMPLEXITY OF THESE RULES AND THE PENALTIES IMPOSED UPON PERSONS
INVOLVED IN PROHIBITED TRANSACTIONS, IT IS PARTICULARLY IMPORTANT THAT POTENTIAL
INVESTORS WHO  ARE PLAN  FIDUCIARIES CONSULT  WITH THEIR  COUNSEL REGARDING  THE
CONSEQUENCES UNDER ERISA OF THEIR ACQUISITION AND OWNERSHIP OF CERTIFICATES.
 
    THE  SALE OF CERTIFICATES TO A PLAN IS IN NO RESPECT A REPRESENTATION BY THE
SELLER OR THE  APPLICABLE UNDERWRITER  THAT THIS INVESTMENT  MEETS ALL  RELEVANT
LEGAL  REQUIREMENTS  WITH  RESPECT  TO INVESTMENTS  BY  PLANS  GENERALLY  OR ANY
PARTICULAR PLAN, OR THAT THIS INVESTMENT  IS APPROPRIATE FOR PLANS GENERALLY  OR
ANY PARTICULAR PLAN.
 
                                LEGAL INVESTMENT
 
    Except  for Standard  Certificates which are  not rated,  as discussed below
under "Rating", the  Certificates other  than Residual Certificates  (and if  so
specified  in the related Prospectus Supplement, the Residual Certificates) will
constitute "mortgage related securities" for purposes of the Secondary  Mortgage
Market Enhancement Act of 1984 (the "Enhancement Act") and as such will be legal
investments  for  persons,  trusts,  corporations,  partnerships,  associations,
business  trusts  and   business  entities   (including  but   not  limited   to
state-chartered  savings banks, commercial banks,  savings and loan associations
and insurance  companies, as  well  as trustees  and state  government  employee
retirement systems) 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
that,  under applicable law, obligations issued by or guaranteed as to principal
and interest  by the  United States  or any  agency or  instrumentality  thereof
constitute legal investments for such entities. Pursuant to the Enhancement Act,
a number of states enacted legislation, on or before the October 3, 1991 cut-off
for such enactments, limiting to varying extents the ability of certain entities
(in particular insurance companies) to invest in mortgage related securities, in
most  cases by  requiring the  affected investors  to rely  solely upon existing
state law, and not the Enhancement  Act. Accordingly, the investors affected  by
such  legislation will be authorized  to invest in the  Certificates only to the
extent provided in such legislation.
 
    The Enhancement Act 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
with mortgage  related securities  without limitation  as to  the percentage  of
their  assets represented thereby, federal credit  unions may invest in mortgage
related securities, and national banks may purchase mortgage related  securities
for  their own account without regard to the limitations generally applicable to
investment securities set forth in 12 U.S.C. 24 (Seventh), subject in each  case
to   such  regulations  as  the  applicable  federal  regulatory  authority  may
prescribe. In  this connection,  federal credit  unions should  review  National
Credit  Union  Administration 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.
The National Credit Union Administration  has adopted rules, effective  December
2,  1991, that prohibit federal credit unions from investing in certain mortgage
related  securities  such  as  the   Residual  Certificates  and  the   Stripped
Certificates, except under limited circumstances.
 
    All  depository institutions  considering an investment  in the Certificates
should review the "Supervisory Policy Statement on Securities Activities"  dated
January  28, 1992 (the "Policy Statement") of the Federal Financial Institutions
Examination Council. The Policy Statement, which  has been adopted by the  Board
of  Governors  of  the Federal  Reserve  System, the  Federal  Deposit Insurance
Corporation,  the  Comptroller  of  the  Currency  and  the  Office  of   Thrift
Supervision, effective February 10, 1992, prohibits depository institutions from
investing  in certain "high-risk mortgage securities" (including securities such
as certain  series  and  classes  of the  Certificates),  except  under  limited
circumstances,  and  sets  forth  certain  investment  practices  deemed  to  be
unsuitable for regulated institutions.
 
    Institutions whose  investment  activities  are  subject  to  regulation  by
federal  or state authorities should review policies and guidelines adopted from
time  to   time   by   such   authorities   before   purchasing   any   of   the
 
                                       94
<PAGE>
Certificates,   as   certain  Series   or   Classes  (in   particular,  Stripped
Certificates)  may  be  deemed  unsuitable  investments,  or  may  otherwise  be
restricted, under such policies or guidelines (in certain instances irrespective
of the Enhancement Act).
 
    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, provisions which
may  restrict   or   prohibit   investment   in   securities   which   are   not
"interest-bearing"  or  "income-paying," and,  with  regard to  any Certificates
issued in book-entry form, provisions which may restrict or prohibit investments
in securities which are issued in book-entry form.
 
    All investors should consult  with their own  legal advisors in  determining
whether  and to  what extent the  Certificates constitute  legal investments for
such investors.
 
                              PLAN OF DISTRIBUTION
 
    The Certificates are being offered hereby  in Series through one or more  of
the  methods  described below.  The  applicable Prospectus  Supplement  for each
Series will describe the method of  offering being utilized for that Series  and
will  state the public offering or purchase  price of each Class of Certificates
of such Series, or the method by which  such price is to be determined, and  the
net proceeds to the Seller from such sale.
 
    The  Certificates will be offered through the following methods from time to
time and  offerings may  be made  concurrently through  more than  one of  these
methods  or  an offering  of a  particular  Series of  Certificates may  be made
through a combination of two or more of these methods:
 
        1.  By negotiated firm commitment underwriting and public re-offering by
    underwriters specified in the applicable Prospectus Supplement;
 
        2.  By placements by the Seller with investors through dealers; and
 
        3.  By direct placements by the Seller with investors.
 
    If underwriters are used  in a sale of  any Certificates, such  Certificates
will  be acquired by  the underwriters for  their own account  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  to be
determined at the  time of  sale or  at the  time of  commitment therefor.  Firm
commitment  underwriting  and  public  reoffering by  underwriters  may  be done
through underwriting syndicates or through one  or more firms acting alone.  The
specific managing underwriter or underwriters, if any, with respect to the offer
and  sale of a particular Series of Certificates  will be set forth on the cover
of the Prospectus Supplement  applicable to such Series  and the members of  the
underwriting syndicate, if any, will be named in such Prospectus Supplement. The
Prospectus  Supplement will describe any discounts and commissions to be allowed
or paid  by  the  Seller  to the  underwriters,  any  other  items  constituting
underwriting  compensation and  any discounts and  commissions to  be allowed or
paid to the  dealers. The  obligations of the  underwriters will  be subject  to
certain  conditions precedent.  The underwriters with  respect to a  sale of any
Class of Certificates will be obligated to purchase all such Certificates if any
are purchased. The Seller  and PHMC will  indemnify the applicable  underwriters
against  certain civil  liabilities, including liabilities  under the Securities
Act of 1933, as amended (the "Act").
 
    The Prospectus Supplement with respect to any Series of Certificates offered
other than through underwriters will contain information regarding the nature of
such offering  and any  agreements to  be entered  into between  the Seller  and
dealers and/or the Seller and purchasers of Certificates of such Series.
 
    Purchasers  of Certificates, including dealers,  may, depending on the facts
and circumstances of such purchases, be  deemed to be "underwriters" within  the
meaning   of  the  Act  in  connection  with  reoffers  and  sales  by  them  of
Certificates. Certificateholders  should consult  with their  legal advisors  in
this regard prior to any such reoffer or sale.
 
                                       95
<PAGE>
    If   specified  in  the  Prospectus  Supplement  relating  to  a  Series  of
Certificates, the Seller or  any affiliate thereof may  purchase some or all  of
one  or more  Classes of  Certificates of  such Series  from the  underwriter or
underwriters at a price  specified or described  in such Prospectus  Supplement.
Such purchaser may thereafter from time to time offer and sell, pursuant to this
Prospectus,  some or all of such Certificates so purchased directly, through one
or more  underwriters to  be designated  at the  time of  the offering  of  such
Certificates  or through dealers acting as agent and/or principal. Such offering
may be restricted in  the matter specified in  such Prospectus Supplement.  Such
transactions may be effected at market prices prevailing at the time of sale, at
negotiated prices or at fixed prices. The underwriters and dealers participating
in  such purchaser's offering  of such Certificates  may receive compensation in
the form of underwriting discounts or  commissions from such purchaser and  such
dealers  may receive commissions from the investors purchasing such Certificates
for whom they may act as agent  (which discounts or commissions will not  exceed
those  customary  in  those types  of  transactions involved).  Any  dealer that
participates in the  distribution of such  Certificates may be  deemed to be  an
"underwriter"  within the meaning of the  Act, and any commissions and discounts
received by such dealer  and any profit  on the resale  of such Certificates  by
such  dealer might be deemed to  be underwriting discounts and commissions under
the Act.
 
    One  or  more  affiliates  of   the  Seller  and  the  Servicer,   including
Prudential-Bache Securities Inc. (which conducts its corporate, governmental and
institutional business under the name Prudential-Bache Capital Funding), may act
as  underwriter or dealer with  respect to Certificates of  any Series. Any such
affiliate will be identified in the applicable Prospectus Supplement.
 
                                 LEGAL MATTERS
 
    Certain legal matters  will be  passed upon  for the  Seller by  Cadwalader,
Wickersham  & Taft, New York, New York and for any underwriters by Brown & Wood,
New York, New York.
 
                                     RATING
 
    It is  a condition  to the  issuance of  the Stripped  Certificates and  the
Multi-Class  Certificates of  any Series that  they be  rated in one  of the two
highest categories by at least one  Rating Agency. Standard Certificates may  or
may not be rated by a Rating Agency.
 
    A  securities rating is not a recommendation to buy, sell or hold securities
and may be subject to revision or withdrawal at any time by the assigning Rating
Agency. Each securities rating  should be evaluated  independently of any  other
