THE PRUDENTIAL HOME MORTGAGE SECURITIES COMPANY, INC.                     [LOGO]
 
                                     SELLER
               MORTGAGE PASS-THROUGH CERTIFICATES, SERIES 1993-11
        PRINCIPAL AND INTEREST PAYABLE MONTHLY, COMMENCING IN APRIL 1996
 
                    VARIABLE RATE(1) CLASS A-11 CERTIFICATES
                     (1) ON THE CLASS A-11 NOTIONAL AMOUNT
                               ------------------
 
    The  Series 1993-11 Mortgage Pass-Through  Certificates (the "Series 1993-11
Certificates") are the Series 1993-11 Certificates described in the accompanying
Prospectus Supplement dated March 11, 1993 (the "Prospectus Supplement") and the
accompanying Prospectus dated  February 5, 1993  (the "Prospectus"). The  Series
1993-11  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 thirteen 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-R and
Class A-LR Certificates. The  Class M and Class  B Certificates are not  divided
into  subclasses. Only the Class A-11 Certificates are being offered hereby. The
Series 1993-11  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. Certain of the Mortgage Loans may be secured primarily
by shares issued  by cooperative  housing corporations. 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.
 
    PROSPECTIVE  INVESTORS IN  THE CLASS  A-11 CERTIFICATES  SHOULD CONSIDER THE
FACTORS DISCUSSED UNDER "RISK FACTORS AND SPECIAL CONSIDERATIONS" HEREIN ON PAGE
S1-3.
 
    The credit  enhancement  for the  Series  1993-11 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-11  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-11
Certificates"  herein and "Description of the Certificates--Principal (Including
Prepayments)" and  "Prepayment  and  Yield  Considerations"  in  the  Prospectus
Supplement and in the Prospectus.

   THESE SECURITIES NOR THE UNDERLYING MORTGAGE LOANS WILL BE INSURED OR

                        CONTRARY IS A CRIMINAL OFFENSE.
                              --------------------
 
    The  Class A-11 Certificates are being offered by Greenwich Capital Markets,
Inc. (the  "Underwriter")  from  time  to  time  to  the  public  in  negotiated
transactions  or otherwise  at varying  prices to be  determined at  the time of
sale. Proceeds to the Seller from the  sale of the Class A-11 Certificates  will
be  approximately  0.80%  of the  Pool  Scheduled  Principal Balance  as  of the
Distribution Date  in April  1996  without giving  effect to  partial  principal
prepayments  or  net  partial  liquidation proceeds  received  on  or  after the
Determination Date in March  1996, plus accrued interest  from March 1, 1996  to
(but  not including)  March 14, 1996,  before deducting expenses  payable by the
Seller estimated to be $45,000. See "Underwriting" herein.
 
    The Class A-11 Certificates are offered by the Underwriter subject to  prior
sale,  when, as and if delivered to  and accepted by the Underwriter and subject
to approval of certain legal matters by counsel. It is expected that delivery of
the Class A-11 Certificates will be made at the offices of the Underwriter,  600
Steamboat Road, Greenwich, Connecticut 06830 on or about March 14, 1996.

(CONTINUED FROM PREVIOUS PAGE)
 
    The   Class  A-11  Certificates  may  not  be  appropriate  investments  for
individual investors.  The  Class  A-11  Certificates  are  offered  in  minimum
denominations  of $162,000,000 initial  Class A-11 Notional  Amount as described
herein under "Description of the Certificates." Except as set forth below, it is
intended that the Class A-11 Certificates not be directly or indirectly held  or
beneficially   owned  by  any   person  in  amounts   lower  than  such  minimum
denomination. The  Class A-11  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-11 Certificates"
herein.
 
    There is currently no secondary market  for the Class A-11 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-11  Certificates.  The
Underwriter  intends to act  as a market  maker in the  Class A-11 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-11 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 the next  succeeding business day to the holders of  record
of  the Class A-11 Certificates on the last business day of the preceding month,
to the extent that their allocable  portion of the Pool Distribution Amount  (as
defined   in  the  Prospectus  Supplement)   is  sufficient  therefor.  On  each
Distribution Date  (as  defined  herein),  to the  extent  funds  are  available
therefor,  the  amount of  interest  distributed in  respect  of the  Class A-11
Certificates will  equal  the interest  accrued  during the  applicable  Regular
Interest Accrual Period (as defined in the Prospectus Supplement). Interest will
accrue   during  each  Regular  Interest  Accrual   Period  on  the  Class  A-11
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-11  Notional Amount  (as
defined  herein), less any  Non-Supported Interest Shortfall  (as defined in the
Prospectus Supplement) and other losses allocable to the Class A-11 Certificates
as  described  in   the  Prospectus   Supplement  under   "Description  of   the
Certificates--Interest."  The Class  A Subclass  Principal Balance  of the Class
A-11  Certificates  as  of  the  Determination  Date  in  March  1996  will   be
approximately   $369.  The  Class  A  Subclass   Principal  Balance  as  of  the
Determination Date  in April  1996  will be  equal to  such  balance as  of  the
Determination  Date in March 1996 reduced by  the amount of any distributions or
other  reductions  of  principal  on  the  Distribution  Date  in  March   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-11  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-11  Certificates and  should be read  only in conjunction  with the Prospectus
Supplement and the Prospectus. Sales of  the Class A-11 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,  both
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 1993-11  Certificates were issued  on March 19,  1993. The Class
A-11 Certificates were not offered to the public at the time of the issuance  of
the Series 1993-11 Certificates.
 
                    RISK FACTORS AND SPECIAL CONSIDERATIONS
 
YIELD CONSIDERATIONS
 
    The  yield  to maturity  of  the Class  A-11  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-11 Certificates may be affected by the
geographic concentration  of  the  Mortgaged Properties  securing  the  Mortgage
Loans.  As of February  16, 1996, Mortgaged Properties  located in the following
states secured at least 5.00% of  the Aggregate Unpaid Principal Balance of  the
Mortgage  Loans: California (65.20%), New York  (10.35%) and New Jersey (5.85%).
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-11 Certificates.  See "Description of the
Mortgage Loans" herein.
 
    AN INVESTOR THAT PURCHASES CLASS A-11 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-11
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  1993-11 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
orginated 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-11  Certificates   will  be  offered   in  fully  registered,
certificated form in  minimum denominations of  $162,000,000 initial Class  A-11
Notional  Amount;  provided, however  that the  Class  A-11 Certificates  may be
issued in minimum denominations of $8,000,000 initial Class A-11 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-11 Certificates, such that
such investor is capable of evaluating the merits and risks of an investment  in
the  Class A-11 Certificates, and (ii) has  a net worth of at least $10,000,000;
or (b) will  hold the Class  A-11 Certificates  solely as nominee  for a  person
meeting the criteria set forth in clause (a). The Class A-11 Certificates may be

Subclass  Principal  Balance  of   the  Class  A-11   Certificates  as  of   the
Determination  Date  in April  1996  will be  equal to  such  balance as  of the
Determination Date in March 1996 reduced by the amount of distributions or other
reductions of principal on the Distribution Date in March 1996.
 
    Distributions of interest and in  reduction of principal balance to  holders
of Class A-11 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 April 1996.
 
    Distributions  (other than the final distribution in retirement of the Class
A-11 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-11
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-11 Certificates will be entitled to a distribution in respect of
interest  accrued during each Regular Interest Accrual Period in an amount up to
such Subclass' Class A  Subclass Interest Accrual Amount.  The Class A  Subclass
Interest  Accrual Amount for the Class  A-11 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-11 Notional Amount.
 
    The Class A Subclass Interest Accrual Amount for the Class A-11 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 0.20% per annum. See "Pooling and Servicing
Agreement--Servicing  Compensation and  Payment of  Expenses" in  the Prospectus
Supplement.
 
    The "Class A-11 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-11 Notional Amount  with
respect   to  the   Distribution  Date   in  February   1996  was  approximately
$137,490,498. The Class A-11  Notional Amount with  respect to the  Distribution
Date  in April 1996 will be equal to the Class A-11 Notional Amount with respect
to the Distribution Date in February 1996, less the difference between the  Pool
Scheduled  Principal Balance with  respect to the  Distribution Date in February
1996 and the Pool Scheduled Principal  Balance with respect to the  Distribution
Date  in April  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-11 Notional Amount was approximately $325,867,093.
 
    The Prospectus Supplement and the Prospectus contain significant  additional
information  concerning  the  characteristics of  the  Class  A-11 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 February 16, 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 February 16, 1996 is its unpaid principal balance as of such
date assuming no  delinquencies and  no prepayments  in full  since February  1,
1996. As of February 16, 1996, the Mortgage Loans included 572 promissory notes,
having  an aggregate Unpaid  Principal Balance (the  "Aggregate Unpaid Principal
Balance")  of   approximately  $135,609,465,   secured  by   first  liens   (the
"Mortgages")  on  one-  to four-family  residential  properties  (the "Mortgaged
Properties"). However, as  of February 16,  1996, three of  such Mortgage  Loans
having  an  aggregate Unpaid  Principal Balance  of approximately  $472,610 have
prepaid in full. Prepayments in full occurring in February 1996 will reduce  the
Class  A-11 Notional Amount with respect to the Distribution Date in April 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 February 16, 1996, each Mortgage Loan had an Unpaid Principal  Balance
of not less than $37,693 or more than $976,413, and the average Unpaid Principal
Balance  of the  Mortgage Loans  was approximately  $237,079. The  latest stated
maturity date of any of  the Mortgage Loans was  November 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, all of the Mortgaged Properties were owner occupied
primary residences. See "PHMC--Mortgage Loan Underwriting" in the Prospectus.
 
    As of February 16, 1996, none of the Mortgage Loans were Subsidy Loans.  See
"The  Trust Estates--Mortgage  Loans" and "PHMC--Mortgage  Loan Underwriting" in
the Prospectus.

</TABLE>
 
As  of  February  16, 1996,  the  minimum  and maximum  Loan-to-Value  Ratios at
origination of the Mortgage  Loans were 16.6% and  90.0%, respectively, and  the
weighted  average Loan-to-Value Ratio  at origination of  the Mortgage Loans was
approximately 71.8%. 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 February 16, 1996, 12 of  the
Mortgage  Loans having  Loan-to-Value Ratios  at origination  in excess  of 80%,
representing approximately 2.47%  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.

As of February 16,  1996, the average Unpaid  Principal Balance of the  Mortgage
Loans  was approximately $237,079. As of February 16, 1996, the weighted average
Loan-to-Value Ratio  at  origination  and the  maximum  Loan-to-Value  Ratio  at
origination  of  the Mortgage  Loans which  had  original principal  balances in
excess of $600,000 were  approximately 62.6% and  70.0%, respectively. See  "The
Trust  Estates--Mortgage Loans"  and "PHMC--Mortgage  Loan Underwriting"  in the

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.

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 February 16,  1996, approximately 29.98% of the  Aggregate

    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.  A
    mortgage   loan  is   no  longer  considered   delinquent  once  foreclosure
    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

                             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 1993-11  Certificates were issued  on March 19,  1993. Set  forth
below  are the  approximate annualized  prepayment rates  of the  Mortgage Loans
underlying the Series  1993-11 Certificates  as a percentage  of CPR  as of  the

</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 1993-11 Certificates  with respect to  April
1993,  reduced by one month for each month thereafter. The prepayment history of
the Mortgage  Loans underlying  the Series  1993-11 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-11
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-11 CERTIFICATE.

                 SENSITIVITY OF THE PRE-TAX YIELD AND WEIGHTED
                  AVERAGE LIFE OF THE CLASS A-11 CERTIFICATES
 
    The  Prospectus Supplement and the  Prospectus contain important information
concerning factors that will affect the  yield and weighted average life of  the
Class  A-11  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-11 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-11 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-11 Certificate is the average amount of time that will elapse from March
14,  1996 until each dollar in reduction  of the principal balance of the Series
1993-11 Certificates is distributed to the holders thereof. The weighted average
life of the Class A-11 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 February  16, 1996, as
described above under "Description of  the Mortgage Loans," adjusted to  reflect
calculated payments of principal on March 1, 1996 assuming a constant prepayment
rate  equal to 0%  CPR for the month  of February 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  S1-8. 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-11 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  first full
paragraph beginning  on page  S-55  of the  Prospectus  Supplement, and  on  the
further  assumptions that (i)  the Class A-11 Certificates  will be purchased on
March  14,  1996  for  an  aggregate  purchase  price  equal  to   approximately
$1,109,248,  which  includes accrued  interest from  March 1,  1996 to  (but not
including)  March  14,  1996,  (ii)  distributions  to  holders  of  Class  A-11
Certificates  will be  made on the  25th day  of each month  commencing in April
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 April 1996, (iv) principal prepayments on the Mortgage Loans will
be received  on the  last day  of each  month commencing  in March  1996 at  the
respective percentages of CPR set forth in the table and there are no Prepayment
Interest  Shortfalls,  (v)  the Class  A-11  Notional Amount  applicable  to the
Distribution Date occurring in April 1996 will be approximately $135,502,755 and
(vi) the Class A Subclass Principal Balance of the Class A-11 Certificates as of
the Determination Date occurring in April 1996 will be approximately $369.

</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-11  Certificates, would  cause the
discounted present  value of  such assumed  stream  of cash  flows to  equal  an
assumed  purchase  price  for  the  Class  A-11  Certificates  of  approximately
$1,109,248 which  includes accrued  interest  from March  1,  1996 to  (but  not
including)  March 14, 1996, and (ii)  converting such monthly rates to corporate
bond equivalent rates. Such
 
                                     S1-19
<PAGE>
calculation 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-11 Certificates and consequently does not purport to reflect the  return
on  any investment in  the Class A-11 Certificates  when such reinvestment rates
are considered.
 
    The weighted average lives of the  Class A-11 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  1993-11
Certificates  by  the  number  of  years from  March  14,  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
1993-11 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-11 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  two REMICs (the
"Upper-Tier REMIC" and the "Lower-Tier 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  and  Class A-11  Certificates, the  Class M
Certificates and  the  Class  B  Certificates  are  designated  as  the  regular
interests  in the Upper-Tier REMIC and the Class A-R and Class A-LR Certificates
are designated as the residual interests in the Upper-Tier REMIC and  Lower-Tier
REMIC, respectively.
 
    The  Class A-11 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-11  Certificates  generally are  treated  as  debt  instruments
originated  on the date of original  issuance of the Series 1993-11 Certificates
for federal income tax purposes. Holders of the Class A-11 Certificates will  be
required  to  report income  thereon in  accordance with  the accrual  method of
accounting. Final and  temporary Treasury regulations  regarding original  issue
discount  (the "OID  Regulations") were issued  on February  2, 1994, indicating
that either the OID Regulations or the Proposed OID Regulations (as defined  and
discussed  in the Prospectus)  may be relied  upon as authority  with respect to
debt instruments issued on the date  of original issuance of the Series  1993-11
Certificates. Although not free from doubt, the Seller believes that, under both
the   OID  Regulations  and  the  Proposed   OID  Regulations,  the  Class  A-11
Certificates are 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).  Any "negative" amounts of original  issue discount on the Class A-11
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-11  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-11 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  1993-11
Certificates,  less distributions  made, and  losses, if  any, incurred,  on the
Class A-11  Certificates since  the  date of  original  issuance of  the  Series
1993-11 Certificates. A purchase price for a Class A-11 Certificate that is less
than  or greater than  the adjusted issue  price of such  Class A-11 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.

                                  UNDERWRITING
 
    Subject to the terms and conditions of an underwriting agreement and a terms
agreement  (together, the "Underwriting  Agreement") among the  Seller, PHMC and
Greenwich Capital Markets, Inc., as  underwriter (the "Underwriter"), the  Class
A-11  Certificates offered  hereby are  being purchased  from the  Seller by the
Underwriter on or about March 14, 1996. The Underwriter is committed to purchase
all of the Class A-11 Certificates offered hereby if any Class A-11 Certificates
are purchased. The Underwriter has advised the Seller that it proposes to  offer
the  Class  A-11  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-11  Certificates are  expected to be
approximately  0.80%  of  the  Pool  Scheduled  Principal  Balance  as  of   the
Distribution  Date  in April  1996 without  giving  effect to  partial principal
prepayments or  net  partial  liquidation  proceeds received  on  or  after  the
Determination  Date in March 1996,  plus accrued interest from  March 1, 1996 to
(but not  including)  March 14,  1996.  The  Underwriter and  any  dealers  that
participate  with  the  Underwriter  in  the  distribution  of  the  Class  A-11
Certificates may be deemed to be underwriters, and any discounts or  commissions
received by them and any profit on the resale of Class A-11 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.
 
                                SECONDARY MARKET
 
    There  will  not be  any secondary  market for  the Class  A-11 Certificates
offered hereby prior to the offering thereof. The Underwriter intends to act  as
a  market maker in the Class A-11 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-11 Certificates will develop  or, if such a market does  develop,
that  it  will provide  holders  of Class  A-11  Certificates with  liquidity of
investment  at  any  particular  time  or  for  the  life  of  the  Class   A-11
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-11 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-11  Certificates, including  the individual
administrative  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-11
Certificates, see "ERISA Considerations" in the Prospectus.
 
    On  September  6, 1990,  the  DOL issued  to  the Underwriter  an individual
administrative exemption, Prohibited Transaction  Exemption 90-59, 55 Fed.  Reg.
36724  (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
 
                                     S1-21
<PAGE>
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-11  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-11 Certificates, is the
condition  that the ERISA  Plan investing in  the Class A-11  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-11 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-11 Certificates. Any  fiduciary
of an ERISA Plan considering whether to purchase a Class A-11 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-11  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-11  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-11 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-11
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-11 Certificates constitute
legal investments for such investors. See "Legal Investment" in the Prospectus.
 
                                 LEGAL MATTERS
 
    The validity of  the Class A-11  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-11 Certificates
will  be applied by  the Seller to the  purchase from an  affiliate of the Class
A-11 Certificates.
 
                                    RATINGS
 
    The Class A-11 Certificates have been  rated "Aaa" by Moody's 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  Moody's on  mortgage pass-through  certificates address the
likelihood  of  the  receipt  by  certificateholders  of  all  distributions  of
principal  and interest to  which such certificateholders  are entitled. Moody's
rating opinions address the structural, legal and issuer aspects associated with
the certificates, including the nature of the underlying mortgage loans and  the
credit  quality of the credit support provider, if any. Moody's ratings on pass-
 
                                     S1-22
<PAGE>
through certificates  do not  represent any  assessment of  the likelihood  that
principal   prepayments  may  differ  from   those  originally  anticipated  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 payments  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 Moody's  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-11  Certificates  may  fail  to  fully  recoup  their  initial
investment.

               MORTGAGE PASS-THROUGH CERTIFICATES, SERIES 1993-11
        PRINCIPAL AND INTEREST PAYABLE MONTHLY, COMMENCING IN APRIL 1993
                             ----------------------
 
    The  Series 1993-11 Mortgage Pass-Through  Certificates (the "Series 1993-11
Certificates") will 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,  and  together,  the
"Subordinated Certificates"). 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. 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.  The  Class  A
Certificates will  consist  of  thirteen  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-R and Class A-LR  Certificates. The Class M  Certificates will not be  divided
into subclasses. For the purpose of determining distributions of interest to the
Class  A-10 Certificates, the Class A-10  Certificates will be deemed to consist
of two components. However, the holder of a Class A-10 Certificate will not have
a severable interest in any one  component, but will have an undivided  interest
in  the entire  Subclass. The  Class A Certificates  (other than  the Class A-11
Certificates) and the Class M  Certificates are referred to herein  collectively
as the "Offered Certificates" and are the only Series 1993-11 Certificates being
offered hereby.

(1) Approximate. The initial Subclass or Class Principal Balances are subject to
    adjustment as described herein.
 
(2) During the initial LIBOR Based Interest Accrual Period, interest will accrue
    on  the Class A-3 Certificates at the  rate of 3.725% per annum. During each
    LIBOR Based Interest Accrual Period thereafter, interest will accrue on  the
    Class  A-3 Certificates at a per annum rate equal to the lesser of (i) 0.60%
    plus the arithmetic mean of the London interbank offered rate quotations for
    one-month  Eurodollar  deposits  determined  monthly  as  set  forth  herein
    ("LIBOR")  and (ii) 10.00%. See  "Description of the Certificates--Interest"
    herein.
 
(3) During the initial LIBOR Based Interest Accrual Period, interest will accrue
    on the Class A-9 Certificates at the  rate of 3.925% per annum. During  each
    LIBOR  Based Interest Accrual Period thereafter, interest will accrue on the
    Class A-9 Certificates at a per annum rate equal to the lesser of (i)  0.80%
    plus  LIBOR and (ii) 10.00%. See "Description of the Certificates--Interest"
    herein.
 
(4) The Class  A-10 Certificates  are  interest only  certificates and  have  no
    principal  balance. For  purposes of determining  distributions of interest,
    the Class A-10 Certificates will be deemed to consist of two components: the
    "Class A-10A Component"  and the  "Class A-10B Component."  The Class  A-10A
    Component  and the  Class A-10B  Component will  bear interest  on the Class
    A-10A Component Notional  Amount (initially  $57,011,000 (approximate))  and
    the   Class   A-10B   Component  Notional   Amount   (initially  $40,813,000
    (approximate)), respectively, as described herein under "Description of  the
    Certificates -- Interest."
 
(5) During the initial LIBOR Based Interest Accrual Period, interest will accrue
    on  the Class A-10A Component  at the rate of  6.275% per annum. During each
    LIBOR Based Interest Accrual Period thereafter, interest will accrue on  the
    Class  A-10A Component  at a per  annum rate,  subject to a  minimum rate of
    0.00% and a maximum rate of 9.40%, equal to 9.40% minus LIBOR, on the  Class
    A-10A  Component Notional  Amount. During  the initial  LIBOR Based Interest
    Accrual Period, interest  will accrue on  the Class A-10B  Component at  the
    rate  of 6.075% per  annum. During each LIBOR  Based Interest Accrual Period
    thereafter, interest will accrue on the Class A-10B Component at a per annum
    rate, subject to a minimum rate of 0.00% and a maximum rate of 9.20%,  equal
    to  9.20% minus  LIBOR, on  the Class  A-10B Component  Notional Amount. See
    "Description of the Certificates-- Interest" herein.
 
(6) On the Class A-LR Notional Amount.
 
    The Offered  Certificates will  be  purchased by  the Underwriter  from  the
Seller and will be offered by the Underwriter from time to time to the public in
negotiated  transactions or otherwise at varying  prices to be determined at the
time of sale. Proceeds to the Seller  from the sale of the Offered  Certificates
will  be 103.21875%  of the aggregate  initial principal balance  of the Offered
Certificates, plus  accrued interest  thereon  and on  an  amount equal  to  the
aggregate  initial principal balance of the  Class A-11 Certificates at the rate
of 8.00% per annum  from March 1,  1993 to (but not  including) March 19,  1993,
before  deducting expenses payable  by the Seller estimated  to be $365,000. The
price to  be  paid to  the  Seller has  not  been allocated  among  the  Offered
Certificates. See "Underwriting" herein.
 
    The  Offered Certificates  are offered by  the Underwriter  subject to prior
sale, when,  as  and if  accepted  by the  Underwriter  and subject  to  certain
conditions.  It is expected that the  Offered Certificates will be available for
delivery through the facilities of The Depository Trust Company or, in the  case
of  the  Class A-10,  Class A-R,  Class A-LR  and Class  M Certificates,  at the
offices of Smith Barney, Harris Upham & Co. Incorporated, New York, New York, in
each case, on or about March 19, 1993.

    The Series 1993-11 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, which may include  loans secured by shares
issued by cooperative housing corporations (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").
See  "Description of the  Mortgage Loans" herein. The  Class A Certificates will
initially evidence in the aggregate an approximate 92.25% undivided interest  in
the  principal  balance of  the Mortgage  Loans. The  Class M  Certificates will
initially evidence in the aggregate  an approximate 2.00% undivided interest  in
the  principal balance  of the Mortgage  Loans. The  remaining approximate 5.75%
undivided interest  in the  principal  balance of  the  Mortgage Loans  will  be
evidenced by the Class B Certificates.
 
    Distributions  in respect of interest and principal 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  a "Distribution  Date"), commencing  in April  1993, to the
holders of Offered  Certificates, as  described herein. The  amount of  interest
accrued  on any Subclass or Class of Offered Certificates will be reduced by any
prepayment interest shortfalls and certain other shortfalls in the collection of
interest from mortgagors, as well as  certain losses, as described herein  under
"Description  of  the  Certificates--Interest." On  any  Distribution  Date, the
holders of the Class M Certificates will receive distributions of interest  only
if the holders of the Class A Certificates have received all amounts of interest
and  of principal  to which  they are  entitled on  such date.  Distributions of
principal to holders of  the Class M  Certificates will be  made only after  the
Class  M Certificates have received the amount of interest due them 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 undivided  Class of Offered Certificates will
be made pro rata among Certificateholders  of such Subclass or Class. The  Class
A-10 Certificates are not entitled to any distributions of principal.
 
    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,  OR IN THE  CASE OF THE  CLASS A-10 CERTIFICATES,  WHICH
HAVE  NO PRINCIPAL BALANCE, 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. INVESTORS IN THE CLASS A-10
CERTIFICATES SHOULD ALSO  CONSIDER THE  RISK THAT A  RAPID RATE  OF PAYMENTS  IN
RESPECT OF PRINCIPAL (INCLUDING PREPAYMENTS) COULD RESULT IN THE FAILURE OF SUCH
INVESTORS  TO FULLY RECOVER THEIR INITIAL INVESTMENTS. THE YIELD TO INVESTORS IN
THE CLASS A-10 CERTIFICATES WILL BE HIGHLY  SENSITIVE TO THE LEVEL OF LIBOR  AND
RELATIVELY  SMALL INCREASES IN THE LEVEL OF  LIBOR WILL HAVE A MATERIAL NEGATIVE
EFFECT ON THE YIELD TO INVESTORS IN THE CLASS A-10 CERTIFICATES AND COULD RESULT
IN THE FAILURE OF SUCH INVESTORS TO FULLY RECOVER THEIR INITIAL INVESTMENTS. THE
YIELD TO MATURITY  OF THE CLASS  M CERTIFICATES  WILL BE MORE  SENSITIVE TO  THE
AMOUNT  AND TIMING OF LOSSES DUE TO  LIQUIDATIONS OF THE MORTGAGE LOANS THAN THE
CLASS A CERTIFICATES, IN THE EVENT THAT  THE CLASS B PRINCIPAL BALANCE HAS  BEEN
REDUCED  TO ZERO. SEE "DESCRIPTION  OF THE CERTIFICATES--INTEREST", "--PRINCIPAL
(INCLUDING  PREPAYMENTS)"  AND  "--  SUBORDINATION  OF  CLASS  M  AND  CLASS   B
CERTIFICATES" HEREIN AND "PREPAYMENT AND YIELD CONSIDERATIONS" HEREIN AND IN THE
PROSPECTUS.
 
    The  Offered Certificates, other than the  Class A-10, Class A-R, Class A-LR
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.
 
    The Offered Certificates may not be an appropriate investment for individual
investors. 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 and any such market
making may be  discontinued at  any time.  There can  be no  assurance that  any
investor  will be  able to sell  an Offered Certificate  at a price  equal to or
greater than the  price at  which such Certificate  was purchased.  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  AND CLASS A-LR CERTIFICATES MAY NOT BE PURCHASED BY OR TRANSFERRED TO (I) A
"DISQUALIFIED ORGANIZATION," (II) EXCEPT UNDER CERTAIN LIMITED CIRCUMSTANCES,  A
PERSON  WHO IS NOT  A "U.S. PERSON," (III)  AN ERISA PLAN OR  (IV) ANY PERSON OR
ENTITY WHO THE  TRANSFEROR KNOWS  OR HAS  REASON TO  KNOW WILL  BE UNWILLING  OR
UNABLE  TO PAY WHEN DUE FEDERAL, STATE  OR LOCAL TAXES WITH RESPECT THERETO. See
"ERISA Considerations"  and "Description  of the  Certificates--Restrictions  on
Transfer  of the  Class A-R,  Class A-LR 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.
 
    For  federal income tax purposes, the Trust  Estate will consist of two real
estate mortgage investment conduits (each a "REMIC" or, in the alternative,  the
"Lower-Tier  REMIC" and the "Upper-Tier REMIC," respectively). 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 and Class
A-11  Certificates, the Class  M Certificates and the  Class B Certificates will
constitute the "regular interests" in the Upper-Tier REMIC and the Class A-R and
Class  A-LR  Certificates  will  constitute  the  "residual  interests"  in  the
Upper-Tier  REMIC and Lower-Tier REMIC,  respectively. PROSPECTIVE INVESTORS ARE
CAUTIONED THAT THE CLASS  A-R CERTIFICATEHOLDER'S REMIC  TAXABLE INCOME AND  THE
TAX LIABILITY THEREON WILL, AND THE CLASS A-LR CERTIFICATEHOLDER'S REMIC TAXABLE
INCOME  AND THE  TAX LIABILITY  THEREON MAY,  EXCEED CASH  DISTRIBUTIONS TO SUCH
HOLDERS DURING CERTAIN PERIODS, IN WHICH EVENT SUCH HOLDERS 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-11 Certificates) represent
twelve 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 February 5, 1993  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.

    THE  FOLLOWING IS  QUALIFIED IN  ITS ENTIRETY  BY REFERENCE  TO THE DETAILED
INFORMATION APPEARING  ELSEWHERE  IN  THIS  PROSPECTUS  SUPPLEMENT  AND  IN  THE
ACCOMPANYING  PROSPECTUS  (THE  "PROSPECTUS"). CAPITALIZED  TERMS  USED  IN THIS
PROSPECTUS SUPPLEMENT  AND  NOT  OTHERWISE  DEFINED  HEREIN  HAVE  THE  MEANINGS
ASSIGNED  IN  THE PROSPECTUS.  SEE "INDEX  OF SIGNIFICANT  PROSPECTUS SUPPLEMENT
DEFINITIONS" HEREIN AND "INDEX OF SIGNIFICANT DEFINITIONS" IN THE PROSPECTUS.

Title of Securities....  Mortgage Pass-Through Certificates, Series 1993-11 (the
                         "Series 1993-11 Certificates" or the "Certificates").
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.
Trustee................  First Trust  National Association,  a national  banking
                         association (the "Trustee"). See "Pooling and Servicing
                         Agreement-- Trustee" in this Prospectus Supplement.
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
                         Moody's  Investors Service, Inc.  ("Moody's") and "AAA"
                         by Standard  &  Poor's  Corporation ("S&P").  It  is  a
                         condition  to the issuance of  the Class M Certificates
                         that they shall  have been rated  "Aa2" by Moody's  and
                         "AA"  by S&P.  The ratings by  Moody's and  S&P 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 1993-11 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
                         represent  a type of  interest referred to  in the Pro-
                         spectus  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  1993-11
                         Certificates. 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  92.25%  (approximately
                         $300,650,000)   undivided  interest  in  the  aggregate
                         initial principal balance  of the  Mortgage Loans;  the
                         Class  M Certificates will evidence in the aggregate an
                         approximate 2.00% (approximately $6,518,000)  undivided
                         interest  in the aggregate initial principal balance of
                         the Mortgage

                         Loans; and the  Class B Certificates  will evidence  in
                         the   aggregate  an  approximate  5.75%  (approximately
                         $18,739,891)  undivided  interest   in  the   aggregate
                         initial  principal balance  of the  Mortgage Loans. The
                         relative  interests   in  the   aggregate   outstanding
                         principal  balance of the Mortgage Loans represented by
                         the Class  A,  Class M  and  Class B  Certificates  are
                         subject   to   change   over   time   because   of  the
                         disproportionate  allocation  of  certain   unscheduled
                         principal  payments to  the Class A  Certificates for a
                         specified period and the  allocation of certain  losses
                         and   certain   shortfalls   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 and shortfalls to the Class A
                         Certificates,  as  discussed  in  "--Distributions   of
                         Principal and Interest" and
                         "--Credit Enhancement" below.
                         The  Class  A  Certificates  will  consist  of thirteen
                         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-R
                         and Class A-LR Certificates.  The Class M  Certificates
                         will  not  be  divided  into  subclasses.  The  Class A
                         Certificates (other than  the Class A-11  Certificates)
                         and  Class  M  Certificates  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-11
                         and Class B Certificates are not offered hereby and may
                         be retained or sold by the Seller.
                         For  purposes of determining distributions of interest,
                         the Class A-10 Certificates  will be deemed to  consist
                         of  two components: the "Class A-10A Component" and the
                         "Class A-10B Component." HOWEVER, THE OWNER OF A  CLASS
                         A-10  CERTIFICATE WILL NOT HAVE A SEVERABLE INTEREST IN
                         ANY ONE COMPONENT, BUT WILL HAVE AN UNDIVIDED  INTEREST
                         IN THE ENTIRE SUBCLASS.
                         The Offered Certificates have the approximate aggregate
                         initial  principal balances  set forth on  the cover of
                         this Prospectus Supplement, except that the Class  A-10
                         Certificates   will  have  no  principal  balance.  Any
                         difference between the  aggregate principal balance  of
                         the  Class A and Class M Certificates as of the date of
                         issuance of  the Series  1993-11 Certificates  and  the
                         approximate  aggregate initial 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-11
                         Certificates),  exceed  5%  of  the  aggregate  initial
                         principal  balance of such  Class A Certificates stated

Forms of Certificates;
  Denominations........  BOOK-ENTRY  FORM.  The Offered Certificates, other than
                         the Class  A-10,  Class A-R,  Class  A-LR 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

                         The  Book-Entry 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.  See

                         registered, certificated form. Accordingly, an investor
                         in any such subclass or class will be issued a physical
                         certificate representing its ownership interest.
                         The Class A-10 Certificates  will be issued in  minimum
                         denominations  of  $5,148,000 initial  notional amount.

                         multiples of $1,000 initial notional amount. The  Class
                         A-R  and Class A-LR Certificates will each be issued as
                         a single  certificate  with a  denomination  of  $1,000
                         initial  principal  balance. The  Class  M Certificates
                         will be  issued in  minimum denominations  of  $100,000

                         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 1993-11 Certificates  (which is expected to
                         occur on or about March  19, 1993). This may result  in
                         changes  in  certain  of the  pool  characteristics set
                         forth  in  the  table  above  and  elsewhere  in   this

                         Certificates, certain  Mortgage  Loans may  be  removed
                         from  the  pool  through repurchase  or,  under certain
                         circumstances,  substitution  by  the  Seller,  if  the

Distributions of
  Principal and
  Interest.............  DISTRIBUTIONS  IN GENERAL. Distributions  on the Series
                         1993-11 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"),  commencing in April 1993, 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.
 
                         The  amount   available   for   distribution   on   any
                         Distribution  Date is  primarily a function  of (i) the
                         amount remitted by mortgagors of the Mortgage Loans  in
                         payment  of their  scheduled installments  of principal
                         and interest, (ii)  the amount of  prepayments made  by
                         the  mortgagors and (iii) proceeds from liquidations of
                         defaulted Mortgage Loans.
 
                         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. The
                         likelihood that a  holder of a  particular subclass  of
                         the  Class A  Certificates (other  than the  Class A-10
                         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

                         any  Distribution  Date  have  been  paid,  the  amount
                         remaining  will be distributed, in the following order,
                         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

                         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  unless the
                         Servicer determines that the delinquent amount will not

                         according to  the  following  formula:  1/12th  of  the
                         pass-through rate for such subclass or class multiplied
                         by  the outstanding principal  balance of such subclass
                         or class as of the related Distribution Date. The pass-

                         The amount of interest to which the holder of the Class
                         A-LR  Certificate  and the  holders  of the  Class A-10
                         Certificates,  with  respect  to  its  components,  are
                         entitled  during  each one-month  period  is calculated
                         based on a  "notional amount." A  notional amount  does
                         not  entitle holders to  receive distributions of prin-
                         cipal on the basis of such notional amount, but is used
                         for the  purpose of  computing the  amount of  interest
                         accrued  on each such subclass. The notional amounts of
                         the Class A-10A Component and the Class A-10B Component
                         correspond to the outstanding principal balances of the
                         Class A-3 Certificates and the Class A-9  Certificates,
                         respectively.   In   the   case  of   the   Class  A-LR
                         Certificate, the  notional amount  is an  amount  other
                         than its actual outstanding principal balance. Interest
                         will  accrue on the Class  A-LR Certificate during each
                         one-month period in an amount  equal to the product  of
                         (i) 1/12th of 8.00% and (ii) the notional amount of the
                         Class  A-LR  Certificate. Interest  will accrue  on the
                         Class A-10A Component and Class A-10B Component  during
                         each one-month period in an amount equal to the product
                         of  (i) 1/12th of the interest  rate then in effect for
                         such component determined as  described below and  (ii)
                         the notional amount of such component.

                         Class A-3 Certificates will be 3.725% per annum. During
                         each  subsequent LIBOR  Based Interest  Accrual Period,
                         the pass-through rate  for the  Class A-3  Certificates

                         During the initial LIBOR Based Interest Accrual Period,
                         interest  will accrue  on the Class  A-10A Component at
                         the rate of  6.275% per annum.  During each  subsequent
                         LIBOR  Based  Interest  Accrual  Period,  interest will
                         accrue on  the Class  A-10A Component  at a  per  annum
                         rate,  subject to a minimum rate of 0.00% and a maximum
                         rate of 9.40%, equal to  9.40% minus LIBOR. During  the
                         initial  LIBOR Based Interest  Accrual Period, interest
                         will accrue on the Class A-10B Component at the rate of
                         6.075% per annum.  During each  subsequent LIBOR  Based
                         Interest  Accrual Period,  interest will  accrue on the
                         Class A-10B Component at a per annum rate, subject to a
                         minimum rate  of 0.00%  and a  maximum rate  of  9.20%,
                         equal to 9.20% minus LIBOR.
 
                         As a result of these calculations, increasing levels of
                         LIBOR  will produce reduced  interest rates (subject to
                         the applicable minimum  rate) for the  Class A-10A  and
                         Class  A-10B  Components,  while  decreasing  levels of
                         LIBOR will produce increased interest rates (subject to
                         the applicable maximum rates).
 
                         Interest will  accrue on  the Class  A-3  Certificates,

                         A-10B Component during each one-month period commencing
                         on  the 25th day  of each month and  ending on the 24th
                         day of  the  following  month  (each,  a  "LIBOR  Based

                         Date  as  a  distribution of  principal  is  the amount
                         remaining   after    all   interest    and    principal
                         distributions  due  on  the  Class  A  Certificates and

                         the original subordination level as protection  against
                         losses  on  the  Class  M  Certificates,  the  Class  B

                         on  certain  Distribution  Dates  to  distributions  of
                         principal.

Credit Enhancement.....  DESCRIPTION  OF "SHIFTING-INTEREST" SUBORDINATION.  The
                         rights of the  holders of the  Class M Certificates  to
                         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 Certificates) against delays in the receipt  of
                         scheduled   payments  of  interest  and  principal  and
                         against  losses  associated  with  the  liquidation  of
                         defaulted  Mortgage Loans and  certain losses resulting
                         from the bankruptcy of a 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  losses  resulting  from  the
                         liquidation   of  defaulted   Mortgage  Loans   or  the
                         bankruptcy of  mortgagors prior  to the  allocation  of
                         such losses to the holders of the Class A Certificates.
 
                         The  protection  afforded the  holders  of the  Class M
                         Certificates by means of  this subordination will  also
                         be  effected in two ways: (i) by the preferential right
                         of the holders of the Class M

                         being  made on any Distribution  Date in respect of the
                         Class B  Certificates,  the  amounts  of  interest  and
                         principal  due the holders of  the Class M 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 B  Certificates and  (ii) by  the
                         allocation  to the holders of  the Class B Certificates
                         of certain  losses resulting  from the  liquidation  of
                         defaulted   Mortgage   Loans  or   the   bankruptcy  of
                         mortgagors prior to  the allocation of  such losses  to
                         the holders of the Class M Certificates.
 
                         In  addition, in  order to  increase the  period during
                         which the principal balances of the Class M and Class B
                         Certificates remain available as credit enhancement  to
                         the  Class A Certificates, 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  Certifi-
                         cates while, in the absence of losses in respect of the
                         liquidation  of  defaulted  Mortgage  Loans  or  losses
                         resulting from the bankruptcy of mortgagors, increasing
                         the respective  percentage  interest in  the  principal
                         balance   of  the  Mortgage   Loans  evidenced  by  the
                         Subordinated Certificates.
 
                         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 $25,257,891) 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  aggregate balance  is expected  initially to be
                         approximately $18,739,891) has been reduced to zero.
 
                         With respect to any Distribution Date subsequent to the
                         first Distribution Date, the availability of the credit
                         enhancement  provided  by  the  Class  M  and  Class  B
                         Certificates 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 and the Class B Certificates  will
                         result  from (i) the prior  allocation of losses due to
                         the liquidation of defaulted Mortgage Loans,  including
                         losses  due to special  hazards and fraud  losses up to
                         the respective limits referred to below, (ii) the prior
                         allocation of bankruptcy losses

                         up to the limit referred  to below and (iii) the  prior
                         receipt  of principal  distributions by  the holders of
                         such class or subclasses. As of the date of issuance of
                         the Series 1993-11 Certificates,  the amount of  losses
                         attributable  to special hazards,  fraud and 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  2.00%,
                         2.00%   and  0.20%,  respectively,   of  the  aggregate
                         principal balance  of  the  Mortgage Loans  as  of  the
                         Cut-Off  Date (approximately $6,526,779, $6,518,158 and
                         $659,136,  respectively).  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,  the Class M Certificates and the 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 then-outstanding
                         principal balances.  Losses that  reduce the  principal
                         balance  of the Class A-3 Certificates will result in a
                         corresponding reduction of the  notional amount of  the
                         Class A-10A Component. Losses that reduce the principal
                         balance  of the Class A-9 Certificates will result in a
                         corresponding reduction of the  notional amount of  the
                         Class   A-10B  Component.   See  "Description   of  the
                         Certificates--Interest" in this Prospectus  Supplement.
                         Under certain circumstances, the limits set forth above
                         may  be reduced as described  under "Description of the

                         BE  MORE SENSITIVE TO LOSSES DUE TO LIQUIDATIONS OF THE
                         MORTGAGE LOANS (AND THE TIMING THEREOF) THAN THE  CLASS
                         A CERTIFICATES, IN THE EVENT 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  cannot  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
                         by  investors.  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, 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

                         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   there  are   no   interest
                         shortfalls and assuming the full return of the purchas-
                         er'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 SUCH INVESTOR'S
                         EXPECTED YIELD. AN INVESTOR THAT PURCHASES ANY  OFFERED
                         CERTIFICATES  AT A PREMIUM, OR THAT PURCHASES ANY CLASS
                         A-10 CERTIFICATES,  WHICH  HAVE NO  PRINCIPAL  BALANCE,
                         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.
 
                         The  yield to investors in the Class A-10 Certificates,
                         which have no principal  balance, will be sensitive  to
                         both  the  timing  of receipt  of  prepayments  and the
                         overall rate of prepayment  on the Mortgage Loans.  The
                         yield  to investors in the Class A-10 Certificates will
                         also be  highly sensitive  to the  level of  LIBOR  and
                         relatively  small increases in the  level of LIBOR will
                         have  a  material  negative  effect  on  the  yield  to
                         investors   in   the  Class   A-10   Certificates.  The
                         particular sensitivities of the Class A-10 Certificates
                         are separately displayed in  the table appearing  under
                         the  heading "Prepayment  and Yield  Considerations" in
                         this Prospectus Supplement. INVESTORS IN THE CLASS A-10
                         CERTIFICATES SHOULD CONSIDER THE RISK THAT A RAPID RATE
                         OF PRINCIPAL PAYMENTS ON THE  MORTGAGE LOANS OR A  HIGH
                         LEVEL  OF  LIBOR COULD  RESULT IN  THE FAILURE  OF SUCH
                         INVESTORS TO FULLY RECOVER THEIR INITIAL INVESTMENTS.
 
                         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 cannot 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 distributions  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 rates on a security is
                         the change in its weighted average life. The  "weighted
                         average life" of an Offered Certificate (other than the
                         Class  A-10 Certificates) is the average amount of time
                         that will elapse  between the date  of issuance of  the
                         Certificate  and  the  date  on  which  each  dollar in
                         reduction of the principal  balance of the  Certificate
                         is  distributed to  the investor.  The weighted average
                         life of a Class A-10 Certificate is the average  amount
                         of  time that will elapse  between the date of issuance
                         of the  Series 1993-11  Certificates  and the  date  on
                         which   each  dollar  in  reduction  of  the  principal
                         balances of the  Class A-3 and  Class A-9  Certificates
                         (which  balances comprise  the notional  amounts of the
                         Class A-10A and  Class A-10B Components,  respectively)
                         is  distributed to the  investors in the  Class A-3 and
                         Class A-9  Certificates. Low  rates of  prepayment  may
                         result in the extension of the weighted average life of
                         a  Certificate; high rates may result 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"   in   this

                         Certificates  will   be  designated   as  the   regular

                         The Regular Certificates (as defined herein)  generally
                         will  be treated  as newly  originated debt instruments
                         for federal income tax  purposes. Beneficial owners  of
                         the  Regular  Certificates will  be required  to report
                         income thereon in accordance with the accrual method of
                         accounting. It is anticipated that the Class A-1, Class

                         A-8  and  Class  M  Certificates will  be  issued  at a

                         Certificates  will be  issued with  DE MINIMIS original
                         issue discount  for federal  income tax  purposes.  The
                         Class A-10 Certificates will be considered to be issued
                         with  original issue discount in an amount equal to the
                         excess of all  distributions of  interest thereon  over
                         their  issue price. The  Class A-11 Certificates, which
                         are not offered hereby, also will be treated as  issued
                         with  original  issue discount  for federal  income tax
                         purposes.

                         of the  Upper-Tier  REMIC  and  the  Lower-Tier  REMIC,
                         respectively,  in  determining  their  federal  taxable
                         income. It  is anticipated  that all  or a  substantial
                         portion  of the taxable income  of the Upper-Tier REMIC
                         and Lower-Tier REMIC  includible by the  Class A-R  and
                         Class  A-LR  Certificateholders, respectively,  will be
                         treated as "excess inclusion" income subject to special

integral multiples of $1,000 initial principal balance in excess thereof.
 
    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-20
<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. In the  event of the
insolvency of  DTC  or a  Participant  or  Indirect Participant  in  whose  name
Book-Entry  Certificates are registered, the ability of the Beneficial Owners of
such Book  Entry Certificates  to  obtain timely  payment  may be  impaired.  In
addition,  in such event, if the limits  of applicable insurance coverage by the
Securities Investor Protection Corporation are  exceeded or if such coverage  is
otherwise unavailable, ultimate payment of amounts distributable with respect to
such Book-Entry Certificates may be impaired.
 
DEFINITIVE CERTIFICATES
 
    The  Class A-10,  Class A-R,  Class A-LR  and 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.
 
                                      S-21
<PAGE>
    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 April  1993, in an  aggregate amount equal  to the Class A
Distribution Amount. 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  business 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 business day preceding
the Determination Date in the month in which such Distribution Date occurs, plus
(i) all Periodic Advances  made by the Servicer,  (ii) all withdrawals from  any
reserve  fund established  to provide support  for the  Servicer's obligation to
make advances,  as described  under "--Periodic  Advances" below  and (iii)  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 or an unreimbursed advance has been made from the  Reserve
    Fund, if established;
 
        (b) any unreimbursed Periodic Advances or unreimbursed advances from the
    Reserve Fund, if established, 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 "--Interest" 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 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
 
                                      S-22
<PAGE>
    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;
 
         (j) Net Foreclosure Profits; and
 
        (k)  any  recovery  of  an  amount in  respect  of  principal  which had
    previously been allocated as  a Realized Loss to  any of the Series  1993-11
    Certificates.
 
    On  each Distribution Date,  the Pool Distribution  Amount will be allocated
among the Classes of  Certificates and distributed to  the holders of record  of
such  Certificates  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  the
    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;
 
        SECOND, to each Subclass of Class A Certificates, pro rata based on  the
    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;
 
        THIRD,  to each Subclass of Class  A Certificates (except the Class A-10
    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  an 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, to the  Class B  Certificates first in  an amount  up to  their
    Class  B Interest  Accrual Amount  with respect  to such  Distribution Date,
    second in an amount up to their previously unpaid interest shortfall  amount
    and then in an amount up to their optimal principal amount.
 
    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
 
                                      S-23
<PAGE>
percentage   obtained  by  dividing  the   initial  principal  balance  of  such
Certificate (or in the  case of the Class  A-10 Certificates, the initial  Class
A-10  Notional Amount of  such Class A-10 Certificate)  by the aggregate initial
principal balance of all Certificates of such Subclass or Class (or in the  case
of the Class A-10 Certificates, the aggregate initial Class A-10 Notional Amount
of the Class A-10 Certificates), as the case may be.
 
INTEREST
    Interest  will accrue on  each Subclass of Class  A Certificates (other than
the Class  A-3, Class  A-9, and  Class A-10  Certificates) and  on the  Class  M
Certificates at their respective Pass-Through Rates during each one-month period
ending  on  the  last  day  of  the month  preceding  the  month  in  which each
Distribution Date  occurs  (each,  a "Regular  Interest  Accrual  Period").  The
initial  Regular Interest  Accrual Period  will be  deemed to  have commenced on
March 1, 1993. Interest which accrues on such Subclasses of Class A Certificates
and on  the Class  M Certificates  will  be calculated  on the  assumption  that
distributions  in reduction of the principal  balances thereof on a Distribution
Date are made  on the  first day  of the month  of such  Distribution Date.  For
purposes  of determining distributions of  interest, the Class A-10 Certificates
will be deemed to consist of two components: the "Class A-10A Component" and the
"Class A-10B Component" (each,  a "Component"). However, the  holder of a  Class
A-10  Certificate will not have  a severable interest in  any one Component, but
will have an undivided interest in the entire Subclass. Interest will accrue  on
the  Class A-3 Certificates,  Class A-9 Certificates,  Class A-10A Component and
Class A-10B  Component  at the  applicable  Pass-Through Rates  described  below
during each one-month period commencing on the 25th day of each month and ending
on  the 24th day of  the following month (each,  a "LIBOR Based Interest Accrual
Period"). The initial LIBOR Based Interest Accrual Period will commence on March
25, 1993.  No interest  will accrue  on the  Class A-3  Certificates, Class  A-9
Certificates,  Class  A-10A Component  and Class  A-10B  Component prior  to the
commencement of the  initial LIBOR  Based Interest Accrual  Period. Interest  on
each  Subclass of Class A  Certificates and on the  Class M Certificates will be
calculated on the basis of a 360-day year consisting of twelve 30-day months.
 
    The amount  of  interest which  will  accrue on  each  Subclass of  Class  A
Certificates  during each Regular Interest Accrual Period or, in the case of the
Class A-3, Class  A-9 and  Class A-10  Certificates, each  LIBOR Based  Interest
Accrual  Period, is referred to herein as the "Class A Subclass Interest Accrual
Amount" for such Subclass. The amount of interest that will accrue on the  Class
A-10A  Component and the Class A-10B  Component during each LIBOR Based Interest
Accrual Period will  be referred to  herein as the  "Component Interest  Accrual
Amount"  for such Component and will be determined as described below. The Class
A Subclass Interest Accrual Amount for the Class A-10 Certificates will be equal
to the sum of the Component Interest Accrual Amounts of its Components.
 
    The Class A Subclass  Interest Accrual Amount for  each Subclass of  Offered
Certificates,  other than the  Class A-10 and the  Class A-LR Certificates, 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 of Offered Certificates, other than the
Class A-3 and Class A-9 Certificates, is  the percentage set forth on the  cover
of  this Prospectus  Supplement. The  Pass-Through Rates  for the  Class A-3 and
Class A-9 Certificates will be determined as described below.
 
    The Class A Subclass Interest Accrual Amount for the Class A-LR  Certificate
will  equal the product of (i) 1/12th of  8.00% and (ii) the Class A-LR Notional
Amount. The  Class  A  Subclass  Interest Accrual  Amount  for  the  Class  A-11
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 as
of the first day of  such month and (b) 8.00%  and (ii) the Class A-11  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.
 
    During  the initial  LIBOR Based  Interest Accrual  Period, the Pass-Through
Rate for  the Class  A-3 Certificates  will  be 3.725%  per annum.  During  each
subsequent LIBOR Based Interest Accrual Period,
 
                                      S-24
<PAGE>
the  Pass-Through Rate for the Class A-3  Certificates will be a per annum rate,
determined on the second business day  preceding the commencement of such  LIBOR
Based  Interest Accrual Period (each, a "Rate Determination Date"), equal to the
lesser of (i)  0.60% plus the  arithmetic mean of  the London interbank  offered
rate  quotations for one-month Eurodollar  deposits ("LIBOR") prevailing on such
Rate Determination Date, determined as described below under "--Determination of
LIBOR" and (ii) 10.00%.
 
    During the initial  LIBOR Based  Interest Accrual  Period, the  Pass-Through
Rate  for  the Class  A-9 Certificates  will  be 3.925%  per annum.  During each
subsequent LIBOR Based Interest  Accrual Period, the  Pass-Through Rate for  the
Class A-9 Certificates will be a per annum rate equal to the lesser of (i) 0.80%
plus  LIBOR, as  determined on the  applicable Rate Determination  Date and (ii)
10.00%.
 
    During the initial LIBOR Based Interest Accrual Period, interest will accrue
on the  Class A-10A  Component at  the rate  of 6.275%  per annum.  During  each
subsequent  LIBOR Based  Interest Accrual  Period, interest  will accrue  on the
Class A-10A Component at a  per annum rate, subject to  a minimum rate of  0.00%
and  a maximum rate of  9.40%, equal to 9.40% minus  LIBOR, as determined on the
applicable Rate  Determination  Date,  on the  Class  A-10A  Component  Notional
Amount.  During the initial  LIBOR Based Interest  Accrual Period, interest will
accrue on the Class A-10B Component at the rate of 6.075% per annum. During each
subsequent LIBOR  Based Interest  Accrual Period,  interest will  accrue on  the
Class  A-10B Component at a  per annum rate, subject to  a minimum rate of 0.00%
and a maximum rate of  9.20%, equal to 9.20% minus  LIBOR, as determined on  the
applicable  Rate  Determination  Date,  on the  Class  A-10B  Component Notional
Amount.
 
    As a result of these calculations,  increasing levels of LIBOR will  produce
reduced  interest rates (subject  to the applicable minimum  rate) for the Class
A-10A and Class A-10B Components, while decreasing levels of LIBOR will  produce
increased interest rates (subject to the applicable maximum rates) for the Class
A-10A and Class A-10B Components.
 
    The  yields  to  investors  in  the Class  A-3,  Class  A-9  and  Class A-10
Certificates will be  affected by  changes in LIBOR.  Levels of  LIBOR may  have
little  or no correlation to levels  of prevailing mortgage loan interest rates.
It is possible that lower prevailing  mortgage loan interest rates (which  might
be  expected to result  in faster prepayments) could  occur concurrently with an
increased level  of LIBOR.  Conversely, it  is possible  that higher  prevailing
mortgage  loan  interest rates  (which  might be  expected  to result  in slower
prepayments) could  occur concurrently  with  a decreased  level of  LIBOR.  See
"Prepayment and Yield Considerations" herein and in the Prospectus.
 
    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 as described below.
 
    The amount of  interest which  will accrue on  the Class  B Certificates  is
referred  to  herein as  the  "Class B  Interest  Accrual Amount."  The  Class B
Interest Accrual Amount will equal the product  of (i) 1/12th of 8.00% and  (ii)
the  outstanding Class B Principal Balance.  The Class B Interest Accrual Amount
will be reduced  by (i)  the portion  of any  Non-Supported Interest  Shortfalls
allocable  to the Class B  Certificates and (ii) the  interest portion of Excess
Special  Hazard  Losses,  Excess  Fraud  Losses  and  Excess  Bankruptcy  Losses
allocable to the Class B Certificates 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 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
 
                                      S-25
<PAGE>
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
Class  A Certificates  on the basis  of their then-outstanding  Class A Subclass
Principal Balances immediately prior to the preceding Distribution Date.
 
    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  Principal Balance" as  of any Determination  Date will be  the
lesser  of (a) the initial principal balance  on the date of initial issuance of
the Class B Certificates less (i) all amounts previously distributed to  holders
of  the Class B 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 B
Certificates 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 and the Class M Principal Balance.
 
    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  1993-11  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 0.20% per annum. See "Pooling and Servicing
Agreement--Servicing Compensation and Payment of Expenses" herein.
 
    The Class  A-10 Certificates  are  interest only  certificates and  have  no
principal  balance. The "Class A-10A Component  Notional Amount" with respect to
each Distribution Date will be equal  to the Class A Subclass Principal  Balance
of  the Class A-3  Certificates. The Class A-10A  Component Notional Amount with
respect to the first  Distribution Date will  be $57,011,000 (approximate).  The
"Class  A-10B Component Notional Amount" with  respect to each Distribution Date
will be  equal to  the  Class A  Subclass Principal  Balance  of the  Class  A-9
Certificates.  The Class  A-10B Component  Notional Amount  with respect  to the
first Distribution  Date  will be  $40,813,000  (approximate). The  "Class  A-10
Notional Amount" with respect to each Distribution Date will be equal to the sum
of  the  Class A-10A  Component Notional  Amount and  the Class  A-10B Component
Notional Amount.
 
    Accordingly, any distributions in respect of principal made to, or losses in
respect of principal allocated in reduction  of, the Class A Subclass  Principal
Balances  of the Class A-3 Certificates will result in a corresponding reduction
in the Class A-10A Component Notional Amount and any distributions in respect of
principal made to, or losses in respect of principal allocated in reduction  of,
the Class A
 
                                      S-26
<PAGE>
Subclass  Principal  Balance of  the  Class A-9  Certificates  will result  in a
corresponding reduction  in  the  Class A-10B  Component  Notional  Amount.  See
"--Principal  (Including Prepayments)" and "--Subordination of Class M and Class
B Certificates--Allocation of Losses" herein.
 
    The "Class A-11 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-11  Notional Amount  with respect  to the first
Distribution Date will be approximately $325,907,891 less any partial  principal
prepayments received in March 1993.
 
    The "Class A-LR 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-LR
Certificate and  the  Class A  Subclass  Principal  Balance of  the  Class  A-11
Certificates.  The  Class  A-LR  Notional  Amount  with  respect  to  the  first
Distribution Date will be $2,000.
 
    Interest shortfalls resulting from 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.  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 to  (i)  the  Class  A
Certificates   according   to   the   percentage   obtained   by   dividing  the
then-outstanding Class A Principal  Balance by the  sum of the  then-outstanding
Class  A  Principal Balance,  Class M  Principal Balance  and Class  B Principal
Balance, (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  and  (iii)  the Class  B  Certificates  according  to the
percentage obtained by dividing the  then-outstanding Class B 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  then  entitled  to distributions  in  respect of
interest. Such allocation of Non-Supported Interest Shortfalls will also  reduce
the  amount of  interest due  to be distributed  to the  holders of  the Class M
Certificates and the  Class B  Certificates. 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 Mortgage  Loans" in  the Prospectus.
Interest shortfalls  resulting  from  the  timing  of  the  receipt  of  partial
principal  prepayments will not  be offset by  Servicing Fees and  will, on each
Distribution Date occurring prior to the Cross-Over Date, be allocated first  to
the Class B Certificates and then to the Class M Certificates before being borne
by  the Class A  Certificates. See "--Subordination  of the Class  M and Class B
Certificates" below.  On  each  Distribution  Date occurring  on  or  after  the
Cross-Over  Date,  any  interest shortfalls  resulting  from the  timing  of the
receipt of  partial  principal  prepayments  will  be  considered  Non-Supported
Interest  Shortfalls  and  will be  allocated  to  the Class  A  Certificates as
described above.
 
    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 will equal  such
Subclass' Class A Subclass Interest Accrual Amount.
 
                                      S-27
<PAGE>
    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.  Any difference between the
portion of  the  Pool Distribution  Amount  distributed in  respect  of  current
interest  to each  Subclass of  Class A  Certificates and  the Class  A Subclass
Interest  Accrual  Amount  for  such  Subclass  with  respect  to  the   related
Distribution Date (as to each 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.
 
    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 Amount immediately prior to such Distribution Date.
 
    On each Distribution Date  on which the Pool  Distribution Amount equals  or
exceeds  the sum for such Distribution Date of (A) the sum of (i) the sum of the
Class A Subclass Interest Accrual Amounts with respect to each Subclass of Class
A Certificates, (ii) the sum of  the unpaid Class A Subclass Interest  Shortfall
Amounts  with respect  to each  Subclass of Class  A Certificates  and (iii) the
Class A Optimal  Principal Amount  (collectively with the  amounts described  in
clauses (i) and (ii), the "Class A Optimal Amount") and (B) 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  Optimal 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 Optimal 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  Class
B  Certificates. With  respect to each  Distribution Date, the  "Class M Optimal
Amount" will equal the sum of (i) the Class M Interest Accrual Amount, (ii)  the
unpaid Class M Interest Shortfall Amount and (iii) the Class M Optimal Principal
Amount.
 
    On  any Distribution Date on which the Pool Distribution Amount is less than
the  Class  A  Optimal  Amount,  the  Class  M  Certificates  and  the  Class  B
Certificates will not be entitled to any distributions of interest or principal.
 
DETERMINATION OF LIBOR
 
    On  each Rate Determination  Date, the Trustee will  determine LIBOR for the
succeeding LIBOR Based Interest Accrual Period on the basis of the offered LIBOR
quotations of  the Reference  Banks,  as such  quotations  are provided  to  the
Trustee  as of 11:00 a.m. (London time) on such Rate Determination Date. As used
herein with respect to a Rate Determination Date, "business day" means a day  on
which  banks are open for dealing in foreign currency and exchange in London and
New  York  City;  "Reference  Banks"   means  four  leading  banks  engaged   in
transactions in Eurodollar deposits in the International Eurocurrency market (i)
with  an established place  of business in London,  (ii) whose quotations appear
 
                                      S-28
<PAGE>
on the Reuters Screen LIBO Page on  the Rate Determination Date in question  and
(iii) which have been designated as such by the Trustee and are able and willing
to  provide such quotations to the Trustee  on each Rate Determination Date; and
"Reuters Screen LIBO Page"  means the display designated  as page "LIBO" on  the
Reuters  Monitor Money Rates Service (or such other page as may replace the LIBO
page on that service for the purpose of displaying London Interbank offered rate
quotations of major  banks). If any  Reference Bank should  be removed from  the
Reuters Screen LIBO Page or in any other way fails to meet the qualifications of
a  Reference  Bank,  the  Trustee  may, in  its  sole  discretion,  designate an
alternative Reference Bank.
 
    On each Rate Determination Date, LIBOR  for the next succeeding LIBOR  Based
Interest Accrual Period will be established by the Trustee as follows:
 
        (i)   If  on any Rate  Determination Date  two or more  of the Reference
    Banks provide  such  offered quotations,  LIBOR  for the  next  LIBOR  Based
    Interest  Accrual  Period  will  be  the  arithmetic  mean  of  such offered
    quotations (rounding  such  arithmetic  mean upwards  if  necessary  to  the
    nearest whole multiple of 1/16%).
 
        (ii) If on any Rate Determination Date only one or none of the Reference
    Banks  provides  such offered  quotations, LIBOR  for  the next  LIBOR Based
    Interest Accrual Period will be the higher of (x) LIBOR as determined on the
    previous Rate  Determination Date  or  (y) the  Reserve Interest  Rate.  The
    "Reserve  Interest  Rate"  will be  the  rate  per annum  which  the Trustee
    determines to be either  (A) the arithmetic  mean (rounding such  arithmetic
    mean  upwards if necessary  to the nearest  whole multiple of  1/16%) of the
    one-month Eurodollar lending rate that New  York City banks selected by  the
    Trustee  are  quoting,  on  the relevent  Rate  Determination  Date,  to the
    principal London  offices  of at  least  two  leading banks  in  the  London
    Interbank  market or (B) in the event that the Trustee can determine no such
    arithmetic mean, the lowest one-month  Eurodollar lending rate that the  New
    York   City  banks  selected  by  the  Trustee  are  quoting  on  such  Rate
    Determination Date to leading European banks.
 
        (iii) If on any Rate Determination  Date the Trustee is required but  is
    unable  to determine  the Reserve  Interest Rate  in the  manner provided in
    paragraph (ii) above, LIBOR for the next LIBOR Based Interest Accrual Period
    will be LIBOR as determined on the previous Rate Determination Date, or,  in
    the case of the first Rate Determination Date, 3.125%.
 
    The  establishment  of LIBOR  by the  Trustee  and the  Trustee's subsequent
calculation of the rates of interest  applicable to the Class A-3  Certificates,
Class  A-9 Certificates, Class A-10A Component and Class A-10B Component for the
relevant LIBOR Based Interest Accrual Period, in the absence of manifest  error,
will  be final and binding. The Pass-Through Rates on the Class A-3 Certificates
and Class A-9 Certificates, and the interest rates on the Class A-10A  Component
and  Class A-10B Component  for any LIBOR  Based Interest Accrual  Period may be
obtained by telephoning the Trustee at (612) 223-7900.
 
PRINCIPAL (INCLUDING PREPAYMENTS)
 
    The principal balance of a Class A Certificate of any Subclass (other than a
Class A-10 Certificate) 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 or Class M Certificate
and (ii)  in  the  case of  the  Class  A-R and  Class  A-LR  Certificates,  any
additional  amounts to which a holder of the Class A-R or Class A-LR Certificate
may be entitled as described below  under "--Additional Rights of the Class  A-R
and Class A-LR Certificateholders") to which the holder thereof is entitled from
the cash flow on 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-10 and
Class A-11 Certificates) and the
 
                                      S-29
<PAGE>
approximate initial Class M Principal Balance are set forth on the cover of this
Prospectus Supplement. The Class A-10 Certificates will have no Class A Subclass
Principal Balance. The initial Class A  Subclass Principal Balance of the  Class
A-11 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 (other  than the  Class A-10  Certificates) will  be made  on  each
Distribution  Date pursuant  to priority THIRD  of the  Pool Distribution Amount
Allocation, in an aggregate amount (the "Class A Principal Distribution 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, as
defined  under  "--Additional   Rights  of   the  Class  A-R   and  Class   A-LR
Certificateholders"  below),  less the  amounts  allocable to  principal  of any
unreimbursed  Periodic  Advances  previously  made  by  the  Servicer  and   any
unreimbursed  advances from  the Reserve Fund  (if established)  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  received by the Servicer 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 and  any unreimbursed advances
from the Reserve Fund (if established)  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 principal 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.
 
                                      S-30
<PAGE>
    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 92.25%. The
Class A  Percentage will  decrease as  a  result of  the allocation  of  certain
unscheduled payments in respect of principal according to 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 March  1998  to  and  including the
Distribution Date in March  1999, the Class A  Percentage for such  Distribution
Date plus 70% of the Subordinated Percentage for such Distribution Date; for any
Distribution  Date subsequent  to March 1999  to and  including the Distribution
Date in March 2000, the Class A  Percentage for such Distribution Date plus  60%
of  the Subordinated Percentage for such Distribution Date; for any Distribution
Date subsequent to March  2000 to and including  the Distribution Date in  March
2001,  the  Class  A Percentage  for  such  Distribution Date  plus  40%  of the
Subordinated Percentage for  such Distribution Date;  for any Distribution  Date
subsequent  to  March  2001 to  and  including  the Distribution  Date  in March
 
                                      S-31
<PAGE>
2002, 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) cumulative Realized Losses  with respect to the Mortgage  Loans
exceed  (a) with  respect to  the Distribution  Date in  April 1998,  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 April 1999, 35% of the Original Subordinated Principal Balance, (c) with
respect to the Distribution Date in April 2000, 40% of the Original Subordinated
Principal  Balance, (d) with respect to the Distribution Date in April 2001, 45%
of the Original  Subordinated Principal  Balance, and  (e) with  respect to  the
Distribution  Date in  April 2002,  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

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),
less the amounts allocable  to principal of  any unreimbursed Periodic  Advances
previously  made by the Servicer and  any unreimbursed advances from the Reserve
Fund (if established) with 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    received    by    the   Servicer    on    or    after
 
                                      S-32
<PAGE>
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 and  any unreimbursed advances  from the Reserve
Fund (if established)  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,  if the  Class B Certificates  are entitled to  principal distributions for
such Distribution Date  as described in  the succeeding paragraph,  the Class  B
Principal Balance.
 
    In   the  event  that  on  any   Distribution  Date,  the  Current  Class  M
Subordination Level is less than the Original Class M Subordination Level,  then
the  Class B Certificates  will not be  entitled to distributions  in respect of
principal and the Class B  Principal Balance 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.
 
    The  "Original Class  M Subordination Level"  is the  percentage obtained by
dividing the initial  Class B  Subclass Principal  Balance by  the Cut-Off  Date
Aggregate  Principal  Balance  of  the  Mortgage  Loans.  The  Original  Class M
Subordination Level is expected to be approximately 5.75%. The "Current Class  M
Subordination  Level" for  any Distribution Date  is the  percentage obtained by
dividing the sum of the then-outstanding Class B Principal Balance 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
 
    The  Class A-10 Certificates have no  principal balance and are not entitled
to principal distributions.
 
    On each Distribution Date occurring prior to the Cross-Over Date, a  portion
of  the Class A Principal Distribution Amount, calculated by multiplying (x) the
fraction equal to $1,000 (I.E., the  initial Class A Subclass Principal  Balance
of  the  Class  A-11 Certificates)  divided  by  the initial  aggregate  Class A
Principal Balance of the  Class A Certificates (which  fraction, expressed as  a
percentage,  is  expected to  be  approximately 0.000333%)  by  (y) the  Class A
Principal Distribution Amount, will be distributed  in reduction of the Class  A
Subclass  Principal Balance of the Class A-11 Certificates. The remainder of the
Class A Principal 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  other Subclasses  of  Class A  Certificates  as
follows:
 
    FIRST,  to the Class A-1 Certificates,  until the Class A Subclass Principal
Balance thereof has been reduced to zero;
 
    SECOND,  concurrently,  (i)  approximately  33.766507%  to  the  Class   A-2
Certificates,  (ii) approximately 45.338255%  to the Class  A-3 Certificates and
(iii) approximately 20.895238% to the Class A-4 Certificates, until the Class  A
Subclass  Principal Balances  of the Class  A-2 and Class  A-3 Certificates have
been reduced to zero;
 
                                      S-33
<PAGE>
    THIRD,  concurrently,  (i)  approximately   59.701559%  to  the  Class   A-4
Certificates  and (ii) approximately  40.298441% to the  Class A-9 Certificates,
until the Class A Subclass Principal  Balance of the Class A-4 Certificates  has
been reduced to zero;
 
    FOURTH,   concurrently,  (i)  approximately  64.516192%  to  the  Class  A-5
Certificates and (ii)  approximately 35.483808% to  the Class A-9  Certificates,
until  the Class A Subclass Principal Balance  of the Class A-5 Certificates has
been reduced to zero;
 
    FIFTH,  concurrently,  (i)  approximately   75.471749%  to  the  Class   A-6
Certificates  and (ii) approximately  24.528251% to the  Class A-9 Certificates,
until the Class  A Subclass  Principal Balance of  each such  Subclass has  been
reduced to zero;
 
    SIXTH,  sequentially, to the Class A-7 and Class A-8 Certificates, until the
Class A Subclass Principal Balances thereof have been reduced to zero; and
 
    SEVENTH, concurrently, to  the Class  A-R and Class  A-LR Certificates,  pro
rata, until the Class A Subclass Principal Balances thereof have been reduced to
zero.
 
    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  (other than  the Class A-10
Certificates) 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 AND CLASS A-LR CERTIFICATEHOLDERS
 
    The  Class A-R  and Class A-LR  Certificates will remain  outstanding for as
long as the Trust Estate shall exist, whether or not they are receiving  current
distributions  of principal or interest. The holders  of the Class A-R and Class
A-LR Certificates 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 1993-11 Certificates, after distributions  in respect of any accrued  but
unpaid  interest on the  Series 1993-11 Certificates  and after distributions in
reduction of principal balance have reduced the principal balances of the Series
1993-11 Certificates (or in the case  of the Class A-10 Certificates, the  Class
A-10  Notional Amount)  to zero. It  is not  anticipated that there  will be any
assets remaining in  the REMICs  on the  final Distribution  Date following  the
distributions  of interest  and in  reduction of  principal balance  made on the
Series 1993-11 Certificates on such date.
 
    In addition,  the Class  A-LR  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
as  of the close  of business on  the business day  preceding such Determination
Date, the  Servicer  will be  obligated  to advance  on  or before  the  related
Distribution  Date for the benefit of holders of the Series 1993-11 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.
 
    In the event that, at some future date, Moody's should revise its assessment
of  the ability  of the Servicer  to make  Periodic Advances, and  so notify the
Trustee in  writing (the  date on  which such  notification is  received by  the
Servicer being referred to herein as the "Reserve Fund Trigger Date"), a reserve
fund (the "Reserve Fund") will be established by the Servicer in accordance with
the provisions of the Pooling and Servicing Agreement to provide limited support
for  the Servicer's obligation to make Periodic Advances, as described above. In
the event that, with respect to  any Distribution Date occurring after the  date
on  which the Reserve  Fund is funded,  the Servicer fails  to make any Periodic
Advance required  to  be  made by  it  pursuant  to the  Pooling  and  Servicing
Agreement,  the Trustee  will cause  to be  withdrawn from  the Reserve  Fund an
advance in an amount equal to the least of (i) the Periodic Advance required  to
be  made by the Servicer  which the Servicer failed to  make, (ii) the excess of
(A) the Class  A Optimal Amount  for such  Distribution Date over  (B) the  Pool
Distribution  Amount (determined without regard to  any advance from the Reserve
Fund on such Distribution Date) and (iii) an amount equal to the amount then  in
the  Reserve Fund, less any reinvestment income  or gain to be released from the
Reserve Fund  as  described  in  the  following  paragraph  (the  "Reserve  Fund
Available  Advance Amount").  The Pooling  and Servicing  Agreement will provide
that any such  advance made  from the  Reserve Fund  will be  reimbursed to  the
Reserve  Fund if and  to the extent  that such reimbursement  would be permitted
under the Pooling and  Servicing Agreement if such  advance had been a  Periodic
Advance  made by the Servicer.  The Reserve Fund, if  established, will not be a
part of the Trust Estate.
 
    The Reserve  Fund, if  required,  will be  established  as a  trust  account
pursuant  to a depository agreement (the  "Depository Agreement") by and among a
depository institution (the  "Reserve Fund  Depository"), the  Servicer and  the
Trustee  and will be held by the  Reserve Fund Depository. Following the Reserve
Fund Trigger Date, should such  date occur, the Reserve  Fund will be funded  by
the  deposit with the Reserve Fund Depository of  an amount in cash equal to (i)
0.50% of the outstanding principal balance of the Mortgage Loans as of the close
of business on  the Reserve  Fund Trigger  Date or  (ii) such  lesser amount  as
Moody's may specify (the "Reserve Fund Required Amount"). After the Reserve Fund
Required  Amount has been deposited in the Reserve Fund, no person will have any
further obligation to  deposit amounts in  the Reserve Fund  or to maintain  the
amounts in the Reserve Fund at that level even if at some future date amounts in
the  Reserve Fund  fall below the  Reserve Fund  Required Amount as  a result of
unreimbursed advances made  from the  Reserve Fund or  withdrawals permitted  by
Moody's.  The amounts in  the Reserve Fund  may be invested  in investments that
will not  cause the  then current  ratings of  the Class  A Certificates  to  be
lowered  by Moody's,  and reinvestment  income or gain  will be  released to the
Servicer (or  its designee)  on each  Distribution Date  free and  clear of  any
interest  of the Trustee, the Reserve Fund Depository or any other person. After
the Class A  Principal Balance  has been  reduced to  zero, any  amounts in  the
Reserve Fund will be released to the Servicer (or its designee).
 
                                      S-35

    An  alternative method of  limited support for  the Servicer's obligation to
make Periodic Advances may be provided, if  such change does not cause the  then
current ratings of the Class A Certificates to be lowered by Moody's.
 
RESTRICTIONS ON TRANSFER OF THE CLASS A-R, CLASS A-LR AND CLASS M CERTIFICATES
 
    The  Class A-R and Class A-LR Certificates  will be subject to the following
restrictions on transfer, and each of the Class A-R and Class A-LR  Certificates
will contain a legend describing such restrictions.
 
    The  REMIC provisions of the Code impose certain taxes on (i) transferors of
residual interests to, or agents that  acquire residual interests on behalf  of,
Disqualified  Organizations  (as defined  in  the Prospectus)  and  (ii) certain
Pass-Through Entities  (as defined  in the  Prospectus) that  have  Disqualified
Organizations  as beneficial  owners. The  Pooling and  Servicing Agreement will
provide that no legal or  beneficial interest in either  the Class A-R or  Class
A-LR  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  things,  such  transferee  is  not  a  Disqualified
Organization and is not purchasing such  Class A-R or Class A-LR Certificate  as
an  agent for a Disqualified Organization (I.E.,  as a broker, nominee, or other
middleman thereof) 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 (i) historically has paid its debts as
they have come due and intends to do so in the future, (ii) understands that  it
may  incur  tax  liabilities  with  respect  to  the  Class  A-R  or  Class A-LR
Certificate in excess of any cash flows generated thereby, (iii) intends to  pay
taxes  associated with holding the  Class A-R or Class  A-LR Certificate as such
taxes become  due  and (iv)  will  not transfer  the  Class A-R  or  Class  A-LR
Certificate  to any person or entity that  does not provide a similar affidavit.
The transferor must certify in  writing to the Trustee that,  as of the date  of
the  transfer, it had no knowledge or  reason to know that the affirmations made
by the transferee pursuant to the preceding sentence were false.
 
    In addition, the Class A-R and Class A-LR Certificates 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  or Class A-LR  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 or Class  A-LR
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--Tax-Related Restrictions on  Transfer of the Residual
Certificates" in the Prospectus.
 
    Neither the Class  A-R Certificate  nor the  Class A-LR  Certificate may  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.
 
REPORTS
 
    In  addition to the applicable information  specified in the Prospectus, the
Servicer will include in the statement delivered to holders of Class A and Class
M Certificates with respect to each Distribution Date
 
                                      S-36
<PAGE>
the following  information: (i)  the amount  of such  distribution allocable  to
interest,  the  amount  of  interest  currently  distributable  on  the  Class A
Certificates allocated to  each Subclass and  to the Class  M Certificates,  any
Class A Subclass Interest Shortfall Amount arising with respect to each Subclass
or  any  Class  M  Interest  Shortfall Amount  on  such  Distribution  Date, any
remaining unpaid Class A Subclass Interest Shortfall Amount with respect to each
Subclass, or  any remaining  unpaid  Class M  Interest Shortfall  Amount,  after
giving  effect to such distribution and  any Non-Supported Interest Shortfall or
the interest portion of Realized Losses allocable to such Subclass or Class with
respect to  such  Distribution  Date,  (ii)  the  amount  of  such  distribution
allocable  to  principal,  (iii) the  Class  A  Principal Balance,  the  Class M
Principal Balance, the Class  A Subclass Principal Balance  of each Subclass  of
Class  A Certificates after  giving effect to the  distribution of principal and
the allocation of Excess Special Hazard  Losses, Excess Fraud Losses and  Excess
Bankruptcy  Losses, if any, (iv) the Adjusted Pool Amount and the Pool Scheduled
Principal Balance of  the Mortgage  Loans for  such Distribution  Date, (v)  the
Class  A Percentage and Class M  Percentage for the following Distribution Date,
and (vi) the amount of the remaining Special Hazard Loss Amount, the Fraud  Loss
Amount  and  the Bankruptcy  Loss Amount  as of  the close  of business  on such
Distribution Date. The statement delivered to  the holders of the Class A-3  and
Class  A-9 Certificates will also include the applicable Pass-Through Rates with
respect to such Distribution Date. The statement delivered to the holders of the
Class A-10 Certificates will also include the applicable interest rates for  the
Class  A-10A and  Class A-10B  Components and  the Class  A-10A and  Class A-10B
Component Notional Amounts. The statement delivered to holders of the Class A-11
Certificates will also include the Class  A-11 Notional Amount and the  weighted
average  Net Mortgage  Interest Rate  of the  Mortgage Loans  applicable to such
Distribution Date minus  8.00%. The  statement delivered  to the  holder of  the
Class  A-LR Certificate  will also include  the Class A-LR  Notional Amount. See
"Servicing  of  the  Mortgage  Loans--Reports  to  Certificateholders"  in   the
Prospectus.
 
    Copies  of the foregoing  reports are available upon  written request to the
Trustee  at  the  Corporate  Trust  Office.  See  "The  Pooling  and   Servicing
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 Certificates and  the 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.
 
                                      S-37
<PAGE>
    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.
 
    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  Optimal Amount and the Class  M Optimal 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  Class B Certificates until  the
Class  B Principal  Balance has 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 Principal Balance 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),  (iii) any  interest shortfalls  resulting from
delinquencies for which  the Servicer  does not  advance and  (iv) any  interest
shortfalls  resulting  from the  timing of  partial principal  prepayments, 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 and the interest 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 Class A Subclass Interest
Accrual Amounts. Any such losses will be allocated among the outstanding Class A
Certificates  within each Subclass pro rata  in accordance with their respective
Percentage Interests. Losses that reduce the principal balances of the Class A-3
Certificates will  result  in  a  corresponding reduction  of  the  Class  A-10A
Component Notional Amount. Losses that reduce the principal balance of the Class
A-9  Certificates will  result in a  corresponding reduction of  the Class A-10B
Component Notional Amount.
 
    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 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).  Losses  that  reduce  the  principal  balances  of  the  Class  A-3
Certificates

will result in a corresponding reduction  of the Class A-10A Component  Notional
Amount.  Losses that reduce the principal  balance of the Class A-9 Certificates
will result in a corresponding reduction  of the Class A-10B Component  Notional
Amount.  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 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 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  1993-11 Certificates, the "Special
Hazard Loss Amount" with  respect thereto will be  equal to approximately  2.00%
(approximately  $6,526,779) 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 (ii)  twice  the  principal balance  of  the single
Mortgage Loan having  the largest  principal balance,  and (iii)  that which  is
necessary  to  maintain  the  original  ratings  on  the  Class  A  and  Class M
Certificates, as evidenced by a  letter to that effect  delivered by S&P to  the
Servicer  and the Trustee. 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 1993-11  Certificates,  the "Fraud  Loss  Amount"  with
respect  thereto will be equal to approximately 2.00% (approximately $6,518,158)
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  Fraud
Loss  Amount will equal 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.  As of any Distribution  Date from the first
through fifth anniversary of the Cut-Off Date, the Fraud Loss Amount will be  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
 
                                      S-39
<PAGE>
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, solely to 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 1993-11 Certificates, the
"Bankruptcy Loss Amount"  with respect  thereto will be  equal to  approximately
0.20%  (approximately $659,136) 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 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
Moody's and S&P that  such reduction or modification  will not adversely  affect
the  then-current ratings assigned  to the Class  A and Class  M Certificates by
Moody's and  S&P. 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 $18,739,891, the risk of Special Hazard Losses,
Fraud Losses  and Bankruptcy  Losses will  separately 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 which  may include loans  secured by  shares
("Co-op   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. The Mortgage Loans are expected to include 1,178 promissory notes, to
have an aggregate unpaid principal balance as of the Cut-Off Date (the  "Cut-Off
Date  Aggregate Principal Balance") of approximately $325,907,891, 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. 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  $34,686  or more  than $999,425,  and the
average unpaid  principal  balance of  the  Mortgage  Loans is  expected  to  be
approximately  $276,662. The latest stated maturity  date of any of the Mortgage
Loans is expected to  be March 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, 1,135 of
the Mortgaged Properties, which secure approximately 97.13% of the Cut-Off  Date
Aggregate  Principal Balance  of the  Mortgage Loans,  are expected  to be owner
occupied primary residences  and 43  of the Mortgaged  Properties, which  secure
approximately  2.87%  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.
 
    It  is expected that  one of the  Mortgage Loans, representing approximately
0.06% of the  Cut-Off Date Aggregate  Principal Balance of  the Mortgage  Loans,
will   be  a  Subsidy  Loan.  See  "The  Trust  Estates--  Mortgage  Loans"  and
"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 1993-11 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
    1993-11  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 minimum  and  maximum  Loan-to-Value  Ratios  at
origination  of  the  Mortgage  Loans  are expected  to  be  16.67%  and 90.00%,
respectively, and the weighted average Loan-to-Value Ratio at origination of the
Mortgage Loans is expected to be approximately 70%. 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. 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. It is expected that
17 of the Mortgage Loans having Loan-to-Value Ratios at origination in excess of
80%, representing approximately  1.61% 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  1993-11
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. 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 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 December 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 $24,516,257,276, 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
    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.  A
    mortgage   loan  is   no  longer  considered   delinquent  once  foreclosure
    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
    the end of each period.
 
(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.

(1) 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.  A
    mortgage   loan  is   no  longer  considered   delinquent  once  foreclosure
    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
    the end of each period.
 
(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
 
                                      S-51
<PAGE>
periods set forth in the preceding tables may be attributable to factors such as
those described above, 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 (other than  the Class A-10  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.
The  rate of prepayment on the Mortgage Loans may also be influenced by programs
offered by mortgage loan originators  (including PHMC) to encourage  refinancing
through  such  originators, including  but not  limited  to general  or targeted
solicitations, reduced origination  fees or  closing costs,  or other  financial
incentives.
 
    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
 
                                      S-52
<PAGE>
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 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 1993-11 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 of 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 and, in the case of the Class A-3,
Class  A-9 and  Class A-10  Certificates, such  investor's own  determination of
LIBOR. 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 such
Subclass or Class is sensitive to the timing of prepayments and, in the case  of
the  Class A-3, Class A-9 and Class A-10 Certificates, the degree to which LIBOR
varies from the level anticipated by  an investor, 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,  or  in  the  case  of  the  Class A-10
Certificates, which  have no  principal balance,  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.
 
                                      S-53
<PAGE>
    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  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.
 
    Investors in the Class A-3 and Class A-9 Certificates should understand that
at levels of  LIBOR greater than  9.40% and 9.20%  per annum, respectively,  the
Pass-Through  Rate  of such  Subclasses  will remain  at  their maximum  rate of
10.00%. Investors  in the  Class  A-3 and  Class  A-9 Certificates  should  also
consider  the risk that lower  than anticipated levels of  LIBOR could result in
actual yields to  such investors  that are  lower than  the anticipated  yields.
Conversely,  investors in the  Class A-10 Certificates  should consider the risk
that higher than anticipated  levels of LIBOR could  result in actual yields  to
such  investors that are significantly  lower than anticipated yields. Investors
in the Class A-10 Certificates should also understand that interest will  accrue
on  the Class A-10A and Class  A-10B Components at a rate  of 0.00% at levels of
LIBOR in  excess  of  9.40%  and 9.20%,  respectively.  Further,  based  on  the
assumptions  set forth in the first paragraph on page S-60, high constant levels
of LIBOR, especially when combined with certain high constant prepayment  rates,
are  expected  to  produce a  negative  yield  to investors  in  the  Class A-10
Certificates. See "--Sensitivity of the Class A-10 Certificates" below.
 
    Investors in the  Class A-3, Class  A-9 and Class  A-10 Certificates  should
understand  that the  timing of  changes in  the level  of LIBOR  may affect the
actual yields to  such investors even  if the average  level is consistent  with
such investors' expectations. Each investor must make an independent decision as
to  the appropriate LIBOR assumptions to be used in deciding whether to purchase
a Class A-3, Class A-9 or Class A-10 Certificate.
 
    As indicated under "Federal Income Tax Considerations" herein, the Class A-R
Certificateholder's REMIC taxable income and the tax liability thereon will, and
the Class A-LR Certificateholder's  REMIC taxable income  and the tax  liability
thereon  may, exceed cash distributions to  such holders 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 and the
Class  A-LR Certificates  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 AND THE CLASS A-LR CERTIFICATES MAY BE SIGNIFICANTLY LOWER THAN  WOULD
BE  THE CASE  IF THE CLASS  A-R AND CLASS  A-LR CERTIFICATES WERE  TAXED AS DEBT
INSTRUMENTS.
 
    As referred to herein, the  weighted average life of  a Subclass of Class  A
Certificates   (other  than  the  Class  A-10  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 a Class A-10 Certificate is the average amount of  time
that will elapse between the date of issuance of the Series 1993-11 Certificates
and  the date on which each dollar in reduction of the principal balances of the
Class A-3  and Class  A-9  Certificates (which  balances comprise  the  notional
amounts  of  the  Class  A-10A  and  Class  A-10B  Components,  respectively) is
distributed to the investors  in the Class A-3  and Class A-9 Certificates.  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
 
                                      S-54
<PAGE>
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, "100% SPA" assumes prepayment rates  equal to 100% 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 in April
1993, (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 in March 1993 at
the respective constant percentages of SPA set forth in the tables and there are
no Prepayment Interest Shortfalls, (v) each  Mortgage Loan has an original  term
to  maturity of 30 years and (vi) the Series 1993-11 Certificates will be issued
on March 19, 1993. 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 (or, in the case of the Class A-10 Certificates, the initial Class
A-10 Notional Amount)  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) With respect to the  Class A-10 Certificates,  percentages are expressed  as
    percentages of the initial Class A-10 Notional Amount.
 
(2) The  weighted average  life of an  Offered Certificate is  determined by (i)
    multiplying the  amount  of  each distribution  in  reduction  of  principal
    balance  or notional amount, as the case may be, 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 or notional amount, as  the
    case may be, referred to in clause (i).

    Interest  on Mortgage Loans prepaid  in full is accrued  only to the date of
such prepayment in full. Any interest  shortfall with respect to prepayments  in
full  will be offset only  to the extent of the  aggregate of the Servicing Fees
relating to mortgagor payments  or other recoveries  distributed on the  related
Distribution  Date. Any excess of such shortfall above the Servicing Fees in any
month will  result in  a pro  rata reduction  of interest  distributable to  the
holders  of each Subclass  of Class A  Certificates, the holders  of the Class M
Certificates and the holders  of the Class  B Certificates. Interest  shortfalls
resulting from the timing of the receipt of partial principal prepayments on the
Mortgage  Loans or from net liquidation  proceeds in respect of Liquidated Loans
will not be offset by Servicing Fees but will be allocated first to the Class  B
Certificates  until  the Class  B Principal  Balance has  been reduced  to zero,
second to the Class M Certificates until the Class M Principal Balance has  been
reduced  to zero  and finally  to the  Subclasses of  Class A  Certificates. See
"Description of  the Certificates--Interest"  herein and  "Prepayment and  Yield
Considerations" in the Prospectus.
 
    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 (other than the Class A-3,  Class
A-9  and Class A-10 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).
 
SENSITIVITY OF THE CLASS A-10 CERTIFICATES
 
    THE  YIELD TO  AN INVESTOR  IN THE  CLASS A-10  CERTIFICATES WILL  BE HIGHLY
SENSITIVE TO THE LEVEL OF LIBOR AND TO THE RATE AND TIMING OF PRINCIPAL PAYMENTS
(INCLUDING  PREPAYMENTS)  OF  THE  MORTGAGE  LOANS,  WHICH  RATE  MAY  FLUCTUATE
SIGNIFICANTLY FROM TIME TO TIME. IN PARTICULAR, THERE MAY BE A MATERIAL NEGATIVE
EFFECT ON THE YIELD TO AN INVESTOR IN THE CLASS A-10 CERTIFICATES AS A RESULT OF
SMALL  INCREASES IN THE LEVEL OF LIBOR OR AS A RESULT OF FASTER THAN ANTICIPATED
PRINCIPAL PREPAYMENTS ON THE MORTGAGE  LOANS. AN INVESTOR SHOULD FULLY  CONSIDER
THE  ASSOCIATED RISKS,  INCLUDING THE  RISK THAT AN  INVESTOR IN  THE CLASS A-10
CERTIFICATES MAY NOT FULLY RECOVER ITS INITIAL INVESTMENT.
 
    Since there can be no assurance that the level of LIBOR will correlate  with
the  levels of  prevailing mortgage  interest rates,  it is  possible that lower
prevailing  mortgage  rates,  which  might  be  expected  to  result  in  faster
prepayments, could occur concurrently with an increased level of LIBOR. However,
if,  as  generally  expected,  higher  mortgage  rates  and,  accordingly, lower
prepayment rates, were to occur concurrently  with an increased level of  LIBOR,
interest  would accrue on the Class A-10A Component and Class A-10B Component at
a reduced rate at the same time  that the rate of distributions in reduction  of
the  principal  balances of  the  Class A-3  and  Class A-9  Certificates (which
principal balances  correspond to  the  Class A-10A  and Class  A-10B  Component
Notional  Amounts,  respectively)  may  be reduced.  In  such  circumstances, an
investor in  the  Class  A-10  Certificates could  have  a  significantly  lower
yielding instrument with a longer weighted average life than anticipated.
 
    To  illustrate  the  significance  of  changes in  the  level  of  LIBOR and
prepayments on the Class  A-10 Certificates, the  following table indicates  the
pre-tax  yields to  maturity (on  a corporate  bond equivalent  basis) under the
assumptions specified  in  the following  paragraph  at the  different  constant
percentages  of SPA and the constant levels of LIBOR indicated. It is not likely
that the Mortgage Loans will prepay at  a CONSTANT level of SPA until  maturity,
that all of the Mortgage Loans will prepay at the same rate or that the level of
LIBOR  will remain constant.  As discussed above,  the timing of  changes in the
rate of prepayments may significantly  affect the total distributions  received,
the date of receipt of such distributions and the actual yield to maturity to an
investor  in a  Class A-10  Certificate, even if  the average  rate of principal
prepayments is  consistent  with  such investor's  expectations.  Moreover,  the
timing  of changes in the level of LIBOR may affect the actual yield to maturity
to an  investor  in a  Class  A-10 Certificate  even  if the  average  level  is
consistent with such investor's expectation.

    The  following table has been  prepared on the basis  of the assumptions set
forth in clauses  (i) through  (vi) of  the first  full paragraph  on page  S-55
hereof, and the additional assumptions that (i) the aggregate purchase price for
the  Class A-10 Certificates is $9,858,411.00,  (ii) such purchase price is paid
on March 19, 1993, (iii) during the initial LIBOR Based Interest Accrual Period,
interest will accrue on the Class A-10A  and Class A-10B Components at the  rate
of  6.275% and 6.075% per annum, respectively and (iv) on the Rate Determination
Date occurring in April 1993 and each Rate Determination Date thereafter,  LIBOR
is  at  the  level  specified. The  Mortgage  Loans  will not  have  all  of the
characteristics assumed above and  there can be no  assurance that the  Mortgage
Loans  will prepay at  any of the  constant rates shown  in the table  or at any
other particular rate,  that the pre-tax  yields to maturity  on the Class  A-10
Certificates  will correspond to any of the  yields shown herein, that the level
of LIBOR  will correspond  to the  levels  shown herein  or that  the  aggregate
purchase price of the Class A-10 Certificates will be as assumed. The table does
not constitute a representation as to the correlation of any level of LIBOR with
any  rate  of prepayments  on the  Mortgage  Loans. Each  investor must  make an
independent decision as to the appropriate prepayment assumptions to be used and
the appropriate levels  of LIBOR to  be assumed  in deciding whether  or not  to
purchase a Class A-10 Certificate.
 
    The  pre-tax yields set forth in the  following 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-10 Certificates  would  cause  the
discounted  present  value of  such assumed  stream  of cash  flows to  equal an
assumed  aggregate  purchase   price  of  $9,858,411.00   for  the  Class   A-10
Certificates and (ii) converting such monthly rates to corporate bond equivalent
rates.  Such calculation does not take into  account the interest rates at which
investors may be able to reinvest funds received by them as distributions on the
Class A-10 Certificates and consequently does not purport to reflect the  return
on  any investment in  Class A-10 Certificates when  such reinvestment rates are
considered.

                        POOLING AND SERVICING AGREEMENT
 
GENERAL
 
    The Series 1993-11  Certificates will be  issued pursuant to  a Pooling  and
Servicing Agreement to be dated as of the date of initial issuance of the Series
1993-11  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 1993-11 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
 
                                      S-60
<PAGE>
the  Certificate Register.  However, with  respect to  any holder  of an Offered
Certificate (other  than  a  Class  A-10  Certificate)  evidencing  at  least  a
$5,000,000  initial principal balance or any  holder of a Class A-10 Certificate
evidencing a $48,000,000 initial Class A-10 Notional Amount, 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
1993-11 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 1993-11  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 1993-11  Certificates. The  aggregate  Voting Interests  of the  Class  A
Certificates  other than the Class A-10 and Class A-11 Certificates, on any date
will be 96% of the Class A Percentage  on such date. The Voting Interest of  the
Class A-10 Certificates on any date will be 3% of the Class A Percentage on such
date.  The aggregate Voting Interest of the  Class A-11 Certificates on any date
will be  1%  of the  Class  A Percentage  on  such date.  The  aggregate  Voting
Interests of each Subclass of Class A Certificates other than the Class A-10 and
Class  A-11 Certificates on any date will be  equal to the product of (a) 96% 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-11 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 1993-11 Certificates will be First Trust National
Association,  a national banking association. The  Corporate Trust Office of the
Trustee is located at 180 East Fifth Street, St. Paul, Minnesota 55101. 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  1993-11
Certificates  and administrative services provided by it will be 0.20% 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
 
                                      S-61
<PAGE>
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 Upper-Tier REMIC  and
the  Lower-Tier  REMIC  will  be  allocated to  the  holders  of  the  Class A-R
Certificate and  Class  A-LR  Certificate, respectively,  who  are  individuals,
estates,  or  trusts (whether  such Certificates  are  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. Unless  and until  applicable
authority  provides otherwise, the Seller intends  to treat all such expenses as
incurred by the Lower-Tier REMIC and,  therefore, as allocable to the holder  of
the    Class    A-LR   Certificate.    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  1993-11
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
Upper-Tier  REMIC  and  the  Lower-Tier  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
 
    For  federal  income tax  purposes,  the Trust  Estate  will consist  of two
segregated asset groupings, each  of which will qualify  as a REMIC for  federal
income  tax  purposes. One  REMIC (the  "Lower-Tier  REMIC") will  issue certain
uncertificated interests (each, a "Lower-Tier REMIC Regular Interest"), each  of
which  will be designated as a regular interest in the Lower-Tier REMIC, and the
Class A-LR Certificate, which will be designated as the residual interest in the
Lower-Tier REMIC. The assets of the  Lower-Tier REMIC will include the  Mortgage
Loans,  together with the amounts held by  the Servicer in a separate account in
which collections  on the  Mortgage Loans  will be  deposited (the  "Certificate
Account"),   the  hazard  insurance  policies  and  primary  mortgage  insurance
policies, if any, relating to the Mortgage Loans and any property which  secured
a Mortgage Loan which is acquired by foreclosure or deed in lieu of foreclosure.
 
    The  second REMIC (the "Upper-Tier REMIC")  will issue all Subclasses of the
Class A  Certificates (other  than  the Class  A-LR  Certificate), the  Class  M
Certificates  and the Class B Certificates. 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 and Class  A-10
Certificates   and  the   Class  M  Certificates   (collectively,  the  "Regular
Certificates"), together  with  the Class  A-11  Certificates and  the  Class  B
Certificates,  will be  designated as  the regular  interests in  the Upper-Tier
REMIC, and the Class A-R Certificate will be designated as the residual interest
in the Upper-Tier REMIC. The regular interests and the residual interest in  the
Upper-Tier  REMIC  are  referred  to  herein  collectively  as  the  "Upper-Tier
Certificates."  The  Class  A-R  and  Class  A-LR  Certificates  are   "Residual
Certificates" for purposes of the Prospectus. The assets of the Upper-Tier REMIC
will  include  the  uncertificated  Lower-Tier  REMIC  Regular  Interests  and a
separate account in which distributions  on the uncertificated Lower-Tier  REMIC
Regular  Interests will  be deposited. The  aggregate amount  distributed to the
holders of the Upper-Tier Certificates, payable from such separate account, will
be equal to the aggregate distributions in respect of the Mortgage Loans on  the
uncertificated Lower-Tier REMIC Regular Interests.
 
                                      S-62
<PAGE>
    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 newly originated  debt
instruments  for federal income tax purposes.  Beneficial owners (or in the case
of Definitive  Certificates,  holders)  of  the  Regular  Certificates  will  be
required  to report income  on such Certificates in  accordance with the accrual
method of accounting.  It is anticipated  that the Class  A-1, Class A-2,  Class
A-4, Class A-5, Class A-6, Class A-7, Class A-8 and Class M Certificates will be
issued  at a premium and  that the Class A-3 and  Class A-9 Certificates will be
issued with DE MINIMIS original issue discount for federal income tax purposes.
 
    The Class A-10 Certificates  will be considered to  be issued with  original
issue discount in an amount equal to the excess of all distributions of interest
thereon  over  their  issue  price. Any  "negative"  amounts  of  original issue
discount on the Class A-10  Certificates attributable to rapid prepayments  with
respect  to the  Class A-3  and Class  A-9 Certificates  will not  be deductible
currently, but may be offset against future positive accruals of original  issue
discount,  if  any. Finally,  the  holder of  a  Class A-10  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 Class  A-11 Certificates, which  are not  offered hereby, also
will be treated as  issued with 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 to
amortize premium, will be calculated using  325% SPA. No representation is  made
as to the actual rate at which the Mortgage Loans will prepay.
 
RESIDUAL CERTIFICATES
 
    The  holders of the Class  A-R and Class A-LR  Certificates must include the
taxable income  or  loss of  the  Upper-Tier  REMIC and  the  Lower-Tier  REMIC,
respectively,  in determining  their federal taxable  income. The  Class A-R and
Class A-LR Certificates 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,   AND   THE   CLASS  A-LR
CERTIFICATEHOLDER'S REMIC  TAXABLE INCOME  AND THE  TAX LIABILITY  THEREON  MAY,
EXCEED CASH DISTRIBUTIONS TO SUCH HOLDERS DURING CERTAIN PERIODS, IN WHICH EVENT
THE  HOLDERS THEREOF  MUST HAVE SUFFICIENT  ALTERNATIVE SOURCES OF  FUNDS TO PAY
SUCH TAX LIABILITY.  Furthermore, it is  anticipated that all  or a  substantial
portion  of  the taxable  income of  the Upper-Tier  REMIC and  Lower-Tier REMIC
includible by  the  holders  of  the Class  A-R  and  Class  A-LR  Certificates,
respectively, will be treated as "excess inclusion" income, resulting in (i) the
inability  of such holder to use net operating losses to offset such income from
the respective REMIC, (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  the REMIC Regulations, because the fair market value of the Class A-R
and Class A-LR Certificates will not exceed  2% of the fair market value of  the
Upper-Tier  REMIC and  Lower-Tier REMIC, respectively,  the Class  A-R and Class
A-LR Certificates 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  REMIC Regulations,  the  Class  A-R
Certificate will, and the Class A-LR Certificate may, be considered "noneconomic
residual interests," with the result that transfers thereof would be disregarded
for federal income tax purposes if any significant purpose of the transferor was
to  impede  the assessment  or collection  of  tax. Accordingly,  the transferee
affidavit used for transfers of the  Class A-R and Class A-LR Certificates  will
require  the transferee to affirm that it (i) historically has paid its debts as
they have come due and intends to do so in the future, (ii) understands that  it
may incur tax
 
                                      S-63
<PAGE>
liabilities with respect to the Class A-R or Class A-LR Certificate in excess of
any  cash flows  generated thereby, (iii)  intends to pay  taxes associated with
holding the Class A-R  or Class A-LR  Certificate as such  taxes become due  and
(iv)  will not transfer the Class A-R or Class A-LR Certificate to any person or
entity that does not provide a similar affidavit. The transferor must certify in
writing to the Trustee that, as of the date of the transfer, it had no knowledge
or reason to know that the affirmations  made by the transferee pursuant to  the
preceding   sentence  were  false.  Finally,  the   Class  A-R  and  Class  A-LR
Certificates generally may  not be transferred  to a  person who is  not a  U.S.
Person  (as defined herein). See  "Description of the Certificates--Restrictions
on Transfer of the Class  A-R, Class A-LR and  Class M Certificates" 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.
 
    Under proposed Treasury regulations relating to original issue discount, the
Lower-Tier  REMIC Regular Interests would be treated as a single debt instrument
for original issue  discount purposes because  they will be  issued in a  single
transaction  to a single holder (the Upper-Tier REMIC). Although there can be no
assurance that  final  regulations  will  apply this  aggregation  rule  to  the
Lower-Tier  REMIC  Regular  Interests,  the Servicer  intends  to  calculate the
taxable income (or net loss) of  the Upper-Tier REMIC and Lower-Tier REMIC  (and
to  report to the Class  A-R and Class A-LR  Certificateholders) by treating the
Lower-Tier REMIC Regular Interests as a single debt instrument. A failure of the
Lower-Tier REMIC Regular Interests  to qualify as a  single debt instrument  for
original  issue discount  purposes could have  a material adverse  impact on the
timing of taxable income to the Class A-LR Certificateholder.
 
    An individual,  trust or  estate that  holds  the Class  A-R or  Class  A-LR
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 properly allocable
to the Upper-Tier REMIC or the Lower-Tier REMIC, respectively, 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, if  any, in  the
Class  A-R or Class A-LR  Certificate may not be  recovered until termination of
the respective REMIC. Furthermore,  the federal income  tax consequences of  any
consideration  paid to a transferee  on a transfer of a  Class A-R or Class A-LR
Certificate are unclear. The  preamble to the  REMIC Regulations indicates  that
the  Internal Revenue Service anticipates providing guidance with respect to the
federal  tax  treatment   of  such  consideration.   Any  transferee   receiving
consideration  with respect  to the Class  A-R or Class  A-LR Certificate should
consult its tax advisors.
 
    DUE TO  THE  SPECIAL TAX  TREATMENT  OF RESIDUAL  INTERESTS,  THE  EFFECTIVE
AFTER-TAX   RETURN  OF  THE  CLASS  A-R  AND  CLASS  A-LR  CERTIFICATES  MAY  BE
SIGNIFICANTLY LOWER THAN  WOULD BE  THE CASE  IF THE  CLASS A-R  AND CLASS  A-LR
CERTIFICATES WERE TAXED AS DEBT INSTRUMENTS.
 
                              ERISA CONSIDERATIONS
 
    Neither  the Class  A-R Certificate  nor the  Class A-LR  Certificate may be
purchased by or  transferred to  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"),  and which  is  subject to  the  fiduciary
responsibility  rules of Sections 401-414 of 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 or Class A-LR 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
 
                                      S-64
<PAGE>
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 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 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  or give rise to 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 PTE
83-1 and other important factors to be considered by an ERISA Plan contemplating
investing in  the  Offered  Certificates,  see  "ERISA  Considerations"  in  the
Prospectus.
 
    On  April  18,  1991,  the  DOL  issued  to  the  Underwriter  an individual
administrative exemption, Prohibited Transaction  Exemption 91-23, 56 Fed.  Reg.
15936  (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  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 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 of 1933, as  amended
(the "Securities Act").
 
    Before  purchasing  an Offered  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 Offered Certificates. Any fiduciary  of
an ERISA Plan considering whether to purchase an Offered 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  Offered  Certificates  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  Offered 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 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
whether   certain   restrictions   may    apply   to   investments   in    other
 
                                      S-65
<PAGE>
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
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 February 18, 1993 (the "Underwriting  Agreement") among the Seller, PHMC  and
Smith   Barney,   Harris  Upham   &  Co.   Incorporated,  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  103.21875% of the
aggregate initial principal balance of  the Offered Certificates, plus  interest
thereon and on an amount equal to the aggregate initial principal balance of the
Class  A-11 Certificates at  the rate of 8.00%  per annum from  March 1, 1993 to
(but not including)  March 19, 1993,  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.
 
    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 1993-11  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 1993-11 Certificates.

                                    RATINGS
 
    It  is a  condition to the  issuance of  the Class A  Certificates that each
Subclass will  have been  rated "Aaa"  by  Moody's and  "AAA" by  S&P. It  is  a
condition  to the issuance of the Class M Certificates that they shall have been
rated  "Aa2"  by  Moody's  and  "AA"  by  S&P.  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  Moody's on  mortgage pass-through  certificates address  the
likelihood  of the receipt  by certificateholders of  all distributions to which
such certificateholders  are  entitled.  Moody's  rating  opinions  address  the
structural,   legal,  issuer   and  tax-related  aspects   associated  with  the
certificates, including  the nature  of the  underlying mortgage  loans and  the
credit  quality  of the  credit  support provider,  if  any. Moody's  ratings on
pass-through certificates do not represent any assessment of the likelihood that
principal prepayments may differ from those originally anticipated.
 
    The ratings  of  S&P  on  mortgage  pass-through  certificates  address  the
likelihood  of the receipt  by certificateholders of  all distributions to which
such  certificateholders  are  entitled.  S&P's  rating  opinions  address   the
structural  and legal  aspects associated  with the  certificates, including the
nature  of  the  underlying  mortgage  loans.  S&P's  ratings  on   pass-through
certificates  do  not represent  any  assessment of  the  likelihood or  rate of
principal prepayments.
 
    The ratings of Moody's  and S&P do  not address the  possibility that, as  a
result  of principal  prepayments, Certificateholders  may receive  a lower than
anticipated yield or that the holders of the Class A-10 Certificates may fail to
fully recover their initial investments.
 
    The Seller has  not requested a  rating on the  Offered Certificates of  any
Subclass or Class by any rating agency other than Moody's and S&P, although data
with  respect to  the Mortgage  Loans may have  been provided  to other agencies
solely for their  informational purposes.  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 Moody's and S&P.

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.

                                    then entitled to  receive such  distributions until  the

                                    Supplement.  This subordination  is intended  to enhance
                                    the likelihood  of  the  timely receipt  by  the  Senior
                                    Certificateholders   of  their  proportionate  share  of
                                    scheduled monthly principal and interest payments on the
                                    related Mortgage  Loans  and  to  protect  them  against
                                    losses.   This  protection  will   be  effected  by  the
                                    preferential right of  the Senior Certificateholders  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
                                    time  to  time  from  payments  on  the  Mortgage  Loans
                                    otherwise distributable to the Subordinated
                                    Certificateholders in  the  manner  and  to  the  extent
                                    specified  in the applicable  Prospectus Supplement. The
                                    maintenance  of  any   Subordination  Reserve  Fund   is
                                    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
                                    interest at  the applicable  Pass-Through Rate,  on  the
                                    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.
                                    If so specified in the applicable Prospectus Supplement,

                                    rights  of holders of  Subordinated Certificates of such

                                    may  be effected by  a method other  than that described
                                    above, such as, in the  event that the applicable  Trust
                                    Estate  (or a segregated pool  of assets therein) elects
                                    to be treated as a REMIC, the reallocation from time  to
                                    time, on the basis of distributions previously received,
                                    of  the  respective percentage  interests of  the Senior
                                    Certificates and  the Subordinated  Certificates in  the

                               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.
 
    The  information with respect to the Mortgage Loans and Mortgaged Properties
described in the  preceding two paragraphs  may be presented  in the  Prospectus
Supplement  for a Series as  ranges in which the  actual characteristics of such
Mortgage Loans and Mortgaged Properties are expected to fall. In all such cases,
information as to the final characteristics of the Mortgage Loans and  Mortgaged
Properties will be available in a Current Report on Form 8-K which will be filed
with  the  Commission within  15 days  of  the initial  issuance of  the related
Series.
 
    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
 
                                       13
<PAGE>
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 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
 
                                       14
<PAGE>
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 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.
 
                                       15
<PAGE>
    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,
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
 
                                       16
<PAGE>
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.
 
    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 Ratio 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
 
                                       17
<PAGE>
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 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  while any Certificates of the Series are
outstanding. 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

    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,

    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

    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;
 
        (vi)  to  the best  of the  Seller's knowledge,  there is  no proceeding

    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

    from the appropriate authorities;

        (xv) the Mortgage Loan  (except any Mortgage  Loan secured by  Mortgaged
    Property  located in  Iowa, as to  which an  opinion of counsel  of the type
    customarily rendered in  such State in  lieu of title  insurance is  instead
    received)  is covered by  an ALTA mortgagee title  insurance policy or other
    generally 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 Mortgaged Property is located  or specifically referred to in the
    appraisal performed  in  connection  with the  origination  of  the  related
    Mortgage  Loan, (C)  liens created pursuant  to any federal,  state or local

    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

    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
 
                                       20
<PAGE>
    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 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 or  with respect to  the absence  or
effect  of  fraud in  the  origination of  any Mortgage  Loan,  and any  loss or
liability resulting  from  the presence  or  effect of  such  hazardous  wastes,
hazardous  substances or fraud  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.

<PAGE>
                        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 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  and the  Trustee of an  affidavit signed by  the transferee stating,
among other things, that the transferee  (i) is not a disqualified  organization
within  the meaning  of Code  Section 860E(e) or  an agent  (including a broker,
nominee, or  middleman) thereof  and  (ii) understands  that  it may  incur  tax
liabilities  in excess  of any  cash flows  generated by  the residual interest.
Further, the transferee must state in the affidavit that it (x) historically has
paid its debts as they have come due, (y) intends to pay its debts as they  come
due  in the  future and  (z) intends  to pay  taxes associated  with holding the
residual interest as they become due. The transferor must certify to the Trustee
that, as of the time of the transfer, it has no actual knowledge that any of the
statements made in the transferee affidavit are false and no reason to know that
the statements made by the  transferee pursuant to clauses  (x), (y) and (z)  of
the   preceding   sentence  are   false.   See  "Certain   Federal   Income  Tax
Consequences--Federal Income Tax

<PAGE>
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 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 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  received  by  the   Servicer  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");
 
                                       24
<PAGE>
           (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  Mortgage  Loan at  the  Net  Mortgage Interest  Rate  for  such
    Mortgage  Loan from the date of its  prepayment in full through the last day
    of the month in which such prepayment in full occurred ("Prepayment Interest
    Shortfall") is included only to the extent that funds for such purposes  are
    available out of the aggregate Servicing Fees; and
 
        (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
 
                                       25
<PAGE>
       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
 
        (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.
 
    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 business day preceding
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 as  described  in  "Servicing  of  the  Mortgage  Loans--Adjustment  to
    Servicing Fee in Connection with Prepaid 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  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;
 
                                       26
<PAGE>
        (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.
 
    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
 
                                       27
<PAGE>
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 and/or (b) 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 (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
    received  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
 
                                       28
<PAGE>
        (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.  The Pool
Scheduled  Principal  Balance  is  determined  after  taking  into  account  all
Curtailments applied by the Servicer on such first day of the month prior to the
month  in  which  such  Distribution Date  falls.  Under  its  current servicing
practices, Curtailments received  in any month  are applied by  the Servicer  in
reduction of the unpaid principal balance of the related Mortgage Loan as of the
first day of such month.
 
    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.
 
    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 not bear interest.
 
    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
 
                                       29
<PAGE>
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 16(D).......  The  Servicer receives scheduled payments of 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 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 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 received 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 received
    on or after

    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 four 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. If so specified  in the related  Prospectus Supplement, such  Series
may include Classes designed to receive principal payments using a predetermined
schedule   such  as   planned  amortization  class   certificates  and  targeted
amortization class certificates and Classes that receive principal payments only
if other designated Classes receive  their scheduled payments. 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
 
- --------------------------------------------------------------------------------
(FOOTNOTES CONTINUED FROM PRECEDING PAGE)
    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 the  close
    of  business on February  16, partial principal  prepayments received 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  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.
 
                                       31
<PAGE>
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 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
 
                                       32
<PAGE>
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
 
                                       33
<PAGE>
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.
 
                                 CREDIT SUPPORT
 
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 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
 
                                       34
<PAGE>
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.
 
    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
 
                                       35
<PAGE>
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.
 
    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."
 
                                       36
<PAGE>
    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 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.
 
                                       37
<PAGE>
    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.
 
  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
 
                                       38
<PAGE>
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 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, an interest shortfall  may
result  depending on the timing of the receipt of the partial prepayment and the
timing of when those  prepayments are passed  through to Certificateholders.  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
 
                                       39
<PAGE>
respect  to any principal prepayment in full 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  to  and including  the  end  of the  month  in  which such
prepayment  in  full  occurs.  Unless  otherwise  specified  in  the  applicable
Prospectus  Supplement, no comparable  offset against the  Servicing Fee will be
provided with respect  to partial  prepayments or liquidations  of any  Mortgage
Loans  and  any  interest shortfall  arising  from partial  prepayments  or from
liquidations either will be covered by means of the subordination of the  rights
of Subordinated Certificateholders or any other credit support arrangements. See
"Servicing of the Mortgage Loans--Adjustment to Servicing Fee in Connection with
Prepaid 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.
 
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
 
                                       40
<PAGE>
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."
 
                                   THE SELLER
 
    The  Prudential  Home Mortgage  Securities Company,  Inc. (the  "Seller"), a
direct, wholly-owned subsidiary  of The Prudential  Home Mortgage Company,  Inc.
("PHMC")  and  an  indirect,  wholly-owned  subsidiary  of  Residential Services
Corporation of America and The Prudential Insurance Company of America, a mutual
insurance  company  organized  under  the  laws  of  the  State  of  New  Jersey
("Prudential  Insurance"), is the  successor in interest  to The Prudential Home
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
of Dryden  Guaranty  Corporation  to The  Prudential  Home  Mortgage  Securities
Company,  Inc. and  to limit the  purposes for  which the Seller  exists and, on
December 28, 1988, the Seller acquired all of the assets and assumed all of  the
liabilities of PHMSCo., including but not limited to all of PHMSCo.'s rights and
obligations  under the  Pooling and Servicing  Agreements relating  to series of
mortgage pass-through certificates previously sold by it.
 
                                       41
<PAGE>
    The limited purposes of the Seller are, in general, to acquire, own and sell
mortgage loans;  to issue,  acquire, own,  hold and  sell mortgage  pass-through
securities  which represent  ownership interests in  mortgage loans, collections
thereon and related properties; and to  engage in any acts which are  incidental
to, or necessary, suitable or convenient to accomplish, the foregoing.
 
    The  Seller  maintains  its principal  office  at 7470  New  Technology Way,
Frederick, Maryland 21701. Its telephone number is (301) 846-8199.
 
    At the time of  the formation of  any Trust Estate, the  Seller will be  the
sole  owner of all the related Mortgage Loans. The Seller will have acquired the
Mortgage Loans included in any Trust Estate from PHMC or another affiliate.  The
Seller's  only obligation with respect to the Certificates of any Series will be
to repurchase or substitute for Mortgage Loans in a Trust Estate in the event of
defective documentation  or  upon the  failure  of certain  representations  and
warranties  made by the Seller. See  "The Trust Estates-- Assignment of Mortgage
Loans to the Trustee."
 
                                      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  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 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
 
                                       43
<PAGE>
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 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  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
 
                                       45
<PAGE>
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 with Loan-to-Value Ratios  less
than  or  equal  to  90%,  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.  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
 
                                       46
<PAGE>
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
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%.
 
                                       47
<PAGE>
    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.

    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 presently intends to subcontract
certain  of  its  administrative  functions  under  the  Pooling  and  Servicing
Agreements  to Securitized  Asset Services  Corporation ("SASCOR").  SASCOR is a
direct, wholly-owned subsidiary of  Residential Services Corporation of  America
and  an affiliate of the Seller and the Servicer. SASCOR was formed on September
23, 1992 to master service residential mortgage loans and to provide  securities
administration   services   in   connection   with   mortgage-backed  securities
transactions. 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") either (i) whose long-term debt obligations (or, in the  case
of  a depository institution which  is part of a  holding company structure, the
long term debt obligations  of which) are,  at the time  of any deposit  therein
rated   at  least  "AA"  (or  the  equivalent)  by  each  nationally  recognized
statistical rating organization that rated  the related Series of  Certificates,
or  (ii) that is  otherwise 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. To the extent that the portion of  funds
deposited  in the Certificate Account at any time exceeds the limit of insurance
coverage established by the Federal Deposit Insurance Corporation (the  "FDIC"),
such  excess  will  be subject  to  loss in  the  event  of the  failure  of the
Depository. Such insurance coverage  will be based on  the number of holders  of
Certificates,  rather than the  number of underlying  mortgagors. Holders of the
Subordinated Certificates of  a Series  of Shifting  Interest Certificates  will
bear  any  such loss  up  to the  amount of  principal  payments on  the related
Mortgage Loans to which such holders are entitled.
 
    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;
 
        (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
 
                                       49
<PAGE>
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  while any Certificates  of the  Series are  outstanding.
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;
 
        (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;
 
                                       50
<PAGE>
       (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 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 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. 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  of a  Mortgage Loan  the amount  of the  aggregate
Servicing  Fees will be offset by an amount  equal to the accrual of interest on
any fully  prepaid Mortgage  Loan at  the Net  Mortgage Interest  Rate for  such
Mortgage  Loan from the date of its prepayment 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 are passed  through to Certificateholders. Unless  otherwise
specified  in  the  applicable  Prospectus  Supplement,  any  interest shortfall
arising from partial  prepayments or  liquidations will  not be  so offset.  See
"Prepayment and
 
                                       51
<PAGE>
Yield Considerations." Payments of the Prepayment 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;

    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 Amount the Stated  Amount
    of the Compound Interest Certificates, if any, 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
    related Distribution Date;
 
       (vii)  the  aggregate amount  of any  Periodic  Advances by  the Servicer
    included in the amounts actually distributed to the Certificateholders;

<PAGE>
       (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
    Servicer  has determined  not to foreclose  because it  believes the related
    Mortgaged Property may be contaminated with or affected by hazardous  wastes
    or hazardous substances; and
 
       (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
 
                                       53
<PAGE>
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)
 
                                       54
<PAGE>
    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 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
 
                                       55
<PAGE>
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.
 
    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,
 
                                       56
<PAGE>
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 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.
 
                                       57
<PAGE>
    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 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;  provided however, that until such  a successor Servicer is appointed and
 
                                       58
<PAGE>
has assumed the responsibilities, duties  and liabilities of the Servicer  under
the Pooling and Servicing Agreement, the Trustee shall continue as the successor
to  the Servicer as described  above. 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
affect the then current rating assigned  to any Certificates, as evidenced by  a
letter  from  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
 
                                       59
<PAGE>
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.
 
    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
 
                                       60
<PAGE>
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

                  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 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
 
                                       61
<PAGE>
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   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.
 
                                       62
<PAGE>
    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.
 
    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.
 
                                       63
<PAGE>
    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 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
 
                                       64
<PAGE>
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,
 
                                       65
<PAGE>
1982, in which that state prohibited the enforcement of "due-on-sale" clauses by
constitutional  provision,  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.
 
                                       66
<PAGE>
    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 regulations (the  "REMIC Regulations") promulgated by the
U.S. Department of the  Treasury on December 23,  1992, and generally  effective
for  REMICs with startup  days on or  after November 12,  1991. 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 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
 
                                       67
<PAGE>
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. 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  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 REMIC Regulations provide a safe harbor pursuant to
which  the DE  MINIMIS requirement  will be  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  REMIC  Pool also  must  provide  "reasonable
arrangements" to prevent its residual interests from being held by "disqualified
organizations"  or agents thereof and must furnish applicable tax information to
transferors or agents that violate  this requirement. See "Taxation of  Residual
Certificates--Tax-Related Restrictions on Transfer of Residual
Certificates--Disqualified Organizations."
 
    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.  The  REMIC
Regulations
 
                                       68
<PAGE>
specify that loans secured  by timeshare interests and  shares held by a  tenant
stockholder  in a cooperative housing corporation  can be qualified mortgages. 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,
earning a return  in the  nature of  interest, 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.
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  amounts due on  the regular or
residual interests in  the event  of defaults (including  delinquencies) on  the
qualified  mortgages,  lower  than  expected  reinvestment  returns,  prepayment
interest shortfalls and certain  other contingencies. 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  extensions granted  by the
Internal Revenue Service.
 
    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 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. Such  a specified  portion  may
consist  of a  fixed number  of basis  points, a  fixed percentage  of the total
interest, or a qualified variable or inverse variable rate on some or all of the
qualified mortgages. 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. 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
 
                                       69
<PAGE>
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 issued on
December 21, 1992 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 Regular  Certificates, and  are subject  to change  and are  not binding
authority before being adopted as  final or temporary regulations. The  Proposed
OID  Regulations are proposed to be effective  for debt instruments issued 60 or
more days after the date the  Proposed OID Regulations are finalized, and  prior
proposed regulations have been withdrawn.
 
    Under  the Proposed OID Regulations, each Regular Certificate (except to the
extent described below with respect to a Regular Certificate on which  principal
is distributed in a single installment or by lots of specified principal amounts
upon  the  request of  a Certificateholder  or  by random  lot (a  "Retail Class
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  offered  pursuant  to  this  Prospectus is  the  price  at  which a
substantial amount of such Class is 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 (in the
case of Standard or Stripped Certificates) or initial Stated Amount (in the case
of Multi-Class Certificates) of the Regular Certificate, but generally will  not
include  distributions of  interest if such  distributions constitute "qualified
stated interest." Under the Proposed OID Regulations, qualified stated  interest
generally  means interest payable at a single fixed rate or a qualified variable
rate  (as   described  below)   provided  that   such  interest   payments   are
unconditionally  payable at intervals of one year or less during the entire term
of the Regular  Certificate. Distributions  of interest on  a Compound  Interest
Certificate,  or on  other Regular Certificates  with respect  to which deferred
 
                                       70
<PAGE>
interest will accrue, will not constitute qualified stated interest payments, in
which case the stated redemption price at maturity of such Regular  Certificates
includes  all distributions of interest as  well as principal thereon. Where the
interval between the  issue date and  the first Distribution  Date on a  Regular
Certificate  is either  longer or shorter  than the  interval between subsequent
Distribution Dates, all or  part of the  interest foregone, in  the case of  the
longer  interval, and all of the additional interest, in the case of the shorter
interval, will be included in the stated redemption price at maturity and tested
under the DE MINIMIS rule described below. The Proposed OID Regulations  suggest
that all interest on a long first period Regular Certificate that is issued with
non-DE  MINIMIS OID will  be treated as OID,  but the Seller  does not intend to
follow  this  approach  unless  and  until  required  to  do  so  by  final  OID
regulations. 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. Holders generally must report DE
MINIMIS OID pro rata as principal payments are received, and such income will be
capital gain if the Regular  Certificate is held as  a capital asset. Under  the
Proposed  OID Regulations, however,  accrual method holders  may elect to accrue
all DE  MINIMIS OID  as  well as  market discount  and  market premium  under  a
constant  interest  method.  Holders  should  consult  their  own  tax  advisors
regarding the method of  making such an  election and the  effect on other  debt
instruments acquired by such holder at a market discount or market premium.
 
    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
purchase  but  excluding the  date  of disposition.  The  Seller will  treat the
monthly period ending  on each  Distribution Date  as the  accrual period.  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. Other than as discussed below
with respect to a Retail Class Certificate, 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, 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
 
                                       71
<PAGE>
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 any reasonable method.
 
    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.
 
    In the case of a Retail Class Certificate, although not entirely clear,  the
yield  to  maturity of  such  Certificate should  be  determined based  upon the
anticipated payment characteristics of the Class as a whole under the Prepayment
Assumption. In  general, the  original issue  discount accruing  on each  Retail
Class  Certificate in a full accrual period  would be its allocable share of the
original issue  discount with  respect to  the entire  Class, as  determined  in
accordance  with the preceding paragraph. However, in the case of a distribution
in retirement  of  the entire  unpaid  principal  balance of  any  Retail  Class
Certificate  (or portion  of such unpaid  principal balance),  (a) the remaining
unaccrued original  issue discount  allocable to  such Certificate  (or to  such
portion)  will accrue at the  time of such distribution,  and (b) the accrual of
original issue discount allocable  to each remaining  Certificate of such  Class
(or  the remaining unpaid principal balance of a partially redeemed Retail Class
Certificate after  a  distribution  of  principal has  been  received)  will  be
adjusted  by reducing the present value of  the remaining payments on such Class
and the adjusted issue  price of such  Class to the  extent attributable to  the
portion of the unpaid principal balance thereof that was distributed.
 
    A  purchaser of a Regular  Certificate at a price  greater than its adjusted
issue price will be required  to include in gross  income the daily portions  of
the  original issue discount  on the Regular  Certificate reduced pro  rata by a
fraction, the numerator of which is the  excess of its purchase price over  such
adjusted issue price and the denominator of which is the excess of the remaining
stated redemption price at maturity over the adjusted issue price.
 
  VARIABLE RATE REGULAR CERTIFICATES
 
    Regular  Certificates may  provide for  interest based  on a  variable rate.
Under the Proposed OID Regulations, interest is treated as payable at a variable
rate and not as contingent interest if, generally, (i) the issue price does  not
exceed  the original  principal balance, and  (ii) the interest  compounds or is
payable at least annually at current values of certain objective rates  measured
by  or  based on  lending rates  for newly  borrowed  funds or  on the  price of
actively traded  property  or an  index  of the  prices  of such  property.  The
variable  interest generally will be qualified  stated interest to the extent it
is unconditionally  payable at  least  annually and,  to the  extent  successive
qualified  floating rates or a fixed rate  followed by a qualified floating rate
are used,  interest is  not significantly  accelerated or  deferred. Because  of
effective  date rules, qualified variable rates for REMIC purposes do not appear
to be  as broad  as for  OID  purposes without  further clarification  from  the
Internal  Revenue Service. The Internal Revenue Service has provided guidance in
Notice 93-11  that  a  rate  that  meets the  definition  in  the  Proposed  OID
Regulations of a "qualified floating rate" (I.E., a floating rate, variations in
which  can reasonably be  expected to measure  contemporaneous variations in the
cost of newly borrowed funds) is  a qualified variable rate for REMIC  purposes.
Accordingly,  under the REMIC  Regulations, a Regular  Certificate (i) bearing a
variable rate  tied to  current values  of  a qualified  floating rate  (or  the
highest,  lowest or average of two or more qualified floating rates, including a
rate based on the average cost of  funds of one or more financial  institutions)
or that represents a weighted
 
                                       72
<PAGE>
average  of rates on some or all of  the Mortgage Loans that bear either a fixed
rate or a qualified floating rate, including such a rate that is subject to  one
or  more caps or floors, or (ii) bearing one or more such variable rates for one
or more periods, or one or more  fixed rates for one or more periods,  qualifies
as a regular interest in a REMIC.
 
    The  Proposed OID  Regulations indicate  that 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  interest will be payable for the
life of the  Regular Certificate at  a reasonable fixed  rate that, taking  into
account  any  actual  discount  from  par, provides  a  yield  to  maturity that
approximates the applicable Federal rate under Code Section 1274(d). The Seller,
however,  unless  and  until  required   to  do  otherwise  by  final   Treasury
regulations,  intends  to  determine  original issue  discount  with  respect to
variable rate Regular Certificates based on the assumption that future  interest
payments  will be  based on  the initial rate  for the  relevant Class. Ordinary
income reportable for any period will be adjusted based on subsequent changes in
the applicable interest rate index.
 
    Although  unclear  at   present,  the  Seller   intends  to  treat   Regular
Certificates  bearing an  interest rate  that is a  weighted average  of the net
interest rates on  Mortgage Loans  having adjustable rates  as having  qualified
stated  interest. In such case, 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 will be tested under
the DE  MINIMIS rules  as described  above.  Adjustments will  be made  in  each
accrual  period either  increasing or decreasing  the amount  of ordinary income
reportable to reflect the actual Pass-Through Rate on the Regular Certificate.
 
  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 adjusted  issue
price  of  such Regular  Certificate  at the  time  of purchase.  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  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
 
                                       73
<PAGE>
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.  Investors should  also consult  Revenue Procedure
92-67 concerning the elections  to include market  discount in income  currently
and to accrue market discount on the basis of a constant interest rate.
 
  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). Such gain will be
treated as  ordinary income  if there  was an  "intention to  call" the  Regular
Certificate  prior  to maturity.  The Proposed  OID  Regulations state  that the
presence of  a sinking  fund or  optional call  does not  give rise  to such  an
intention,  and the Seller does not believe  such an intention will otherwise be
present with respect to  a Series of Certificates,  although the application  of
these rules to Retail Class Certificates is unclear. In addition, such gain will
be  treated as ordinary income to the extent  that such gain does not exceed the
excess, if any, of (i) the amount  that would have been includible in 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, to the extent the REMIC
Pool  consists of fixed rate Mortgage Loans, interest income with respect to any
given Mortgage  Loan will  remain 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  a  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
 
                                       75
<PAGE>
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.
The REMIC  Regulations  appear to  treat  the issue  price  of such  a  residual
interest  as zero rather  than such negative amount  for purposes of determining
the REMIC Pool's  basis in  its assets. The  preamble to  the REMIC  Regulations
states  that the  Internal Revenue  Service may  provide future  guidance on the
proper tax  treatment  of payments  made  by a  transferor  of such  a  residual
interest  to induce the transferee to acquire the interest, and Residual Holders
should consult their own tax advisors in this regard.
 
    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  future  Treasury  regulations  provide  for   periodic
adjustments  to the REMIC income otherwise  reportable by such holder. The REMIC
Regulations currently in  effect 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.
 
  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 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
 
                                       76
<PAGE>
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 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  REMIC Regulations have not  adopted
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
 
                                       77
<PAGE>
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, if  a real  estate investment  trust or  a regulated  investment
company  owns  a  Residual  Certificate,  a  portion  (allocated  under Treasury
regulations yet to be  issued) of dividends paid  by the real estate  investment
trust  or  regulated investment  company 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.
 
    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. 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
weighted average life of the REMIC  Pool. The anticipated weighted average  life
of  the Residual  Certificates is based  on all distributions  anticipated to be
received with respect thereto (using the Prepayment Assumption). The anticipated
weighted average life of the REMIC  Pool is the aggregate weighted average  life
of   all  classes   of  interests   therein  (computed   using  all  anticipated
distributions on a regular interest with  nominal or no principal). Finally,  an
ordering rule under the REMIC Regulations provides that a thrift institution may
only  offset  its excess  inclusion income  with deductions  after it  has first
applied its deductions against  income that is not  excess inclusion income.  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 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  corporations.  The   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  ending  with the  last  calendar quarter  in  which excess  inclusions are
expected to accrue. 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 stating 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 Internal Revenue
Service 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.
 
                                       78
<PAGE>
    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 furnishes to the
Seller and the Trustee an affidavit providing its taxpayer identification number
and stating  that  such transferee  is  the  beneficial owner  of  the  Residual
Certificate  and is not  a Disqualified Organization and  is not purchasing such
Residual Certificate  on  behalf of  a  Disqualified Organization  (I.E.,  as  a
broker,  nominee,  or  middleman thereof)  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
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 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 REMIC Regulations,  a transfer of a "noneconomic  residual
interest"  (as 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 if a significant purpose of the
transferor 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
 
                                       79
<PAGE>
anticipated  excess inclusions  in an amount  sufficient to  satisfy the accrued
taxes on  each  excess inclusion.  The  anticipated excess  inclusions  and  the
present  value rate are determined  in the same manner  as set forth above under
"Disqualified Organizations." The REMIC  Regulations explain that a  significant
purpose  to impede the assessment or collection of tax exists if the transferor,
at the  time  of  the transfer,  either  knew  or should  have  known  that  the
transferee  would be unwilling  or unable to pay  taxes due on  its share of the
taxable income of the  REMIC. A safe  harbor is provided  if (i) the  transferor
conducted,  at  the time  of  the transfer,  a  reasonable investigation  of the
financial condition of the transferee and found that the transferee historically
had paid  its debts  as  they came  due and  found  no significant  evidence  to
indicate  that the transferee would  not continue to pay  its debts as they came
due in the future, and (ii) the transferee represents to the transferor that  it
understands  that,  as the  holder of  the  non-economic residual  interest, the
transferee may incur tax  liabilities in excess of  any cash flows generated  by
the  interest  and that  the  transferee intends  to  pay taxes  associated with
holding the residual  interest as  they become  due. The  Pooling and  Servicing
Agreement  with  respect  to  each  Series  of  Certificates  will  require  the
transferee of a Residual Certificate to certify to the matters in the  preceding
sentence   as  part  of   the  affidavit  described   above  under  the  heading
"Disqualified Organizations."
 
    FOREIGN INVESTORS.   The 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 and prior to the end of the next
succeeding taxable  year for  the accumulated  withholding tax  liability to  be
paid.  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  it from the  REMIC Pool exceeds  such
adjusted  basis on that Distribution  Date. Such income will  be treated as gain
from the sale or exchange 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 its  Residual Certificate remaining when  its interest in  the
REMIC  Pool terminates, and if  it holds such Residual  Certificate as a capital
asset under Code Section  1221, then it  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
 
                                       80
<PAGE>
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 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 or  due-on-encumbrance 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 adopts a plan of complete liquidation, within the meaning of
Code Section 860F(a)(4)(A)(i), which may  be accomplished by designating in  the
REMIC  Pool's final tax return a date on which such adoption is deemed to occur,
and sells all of its assets (other  than cash) within a 90-day period  beginning
on  such date, the REMIC Pool will recognize no  gain or loss on the sale 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
 
                                       81
<PAGE>
income  tax return  is Form 1066,  U.S. Real Estate  Mortgage Investment Conduit
Income Tax  Return.  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 "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
 
                                       82
<PAGE>
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 31% 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,  original  issue  discount  and  information
necessary to compute the accrual of market 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 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
 
                                       83
<PAGE>
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.
 
    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 or a "taxable mortgage pool" within the meaning of Code
Section  7701(i). 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) (in  each case,  as adjusted  for
inflation), or (ii) 80% of the amount of itemized deductions otherwise allowable
for  such  year.  As a  result,  such investors  holding  Standard Certificates,
directly or 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
 
                                       84
<PAGE>
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.
 
  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.
 
                                       85
<PAGE>
    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 original issue discount rules of Code Sections
1271  through 1275 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.
Under the Proposed OID Regulations, such original issue discount could arise  by
the  charging of points by the originator  of the mortgages in an amount greater
than the statutory DE MINIMIS exception,  including a payment of points that  is
currently  deductible by the borrower under applicable Code provisions or, under
certain circumstances, by the presence of "teaser" rates on the Mortgage Loans.
 
    Original issue discount generally must be reported as ordinary gross  income
as  it accrues  under a  constant interest  method that  takes into  account the
compounding of interest,  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 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."  Subject to the DE  MINIMIS rule discussed below
under "--Stripped Certificates," 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
 
                                       86
<PAGE>
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  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 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.
 
                                       87
<PAGE>
    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 or a "taxable mortgage pool" within the meaning of Code
Section  7701(i),  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 two or
more debt instruments issued by a single issuer to a single investor in a single
transaction should be treated as a single debt instrument. Accordingly, for  OID
purposes,  all payments  on any Stripped  Certificates should  be aggregated and
treated as though they were  made on a single  debt instrument. The Pooling  and
Servicing   Agreement  will  require  that  the  Trustee  make  and  report  all
computations described below using  this aggregate approach, unless  substantial
legal authority requires otherwise.
 
    Furthermore,  Treasury  regulations  issued December  28,  1992  provide for
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 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
indicates that the interest  component of such a  Stripped Certificate would  be
treated  as  qualified  stated  interest  under  the  Proposed  OID Regulations.
Further, these final 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 doubt, counsel  has
advised the Seller that Stripped Certificates owned by applicable holders should
be
 
                                       88
<PAGE>
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 proposed Treasury
regulations issued April 8, 1986 (the "Prior Proposed OID Regulations"). If  the
rules  of the  Prior 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
 
                                       89
<PAGE>
applied  to  the  adjusted  basis of  the  Stripped  Certificate,  while amounts
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.  When 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.  Final  regulations issued  on December  28, 1992  regarding original
issue discount on stripped obligations  make the foregoing interpretations  less
likely  to be applicable. The preamble to those regulations states that they are
premised on  the assumption  that  an aggregation  approach is  appropriate  for
determining  whether  original issue  discount on  a  stripped bond  or stripped
coupon is DE MINIMIS, and solicits comments on appropriate rules for aggregating
stripped bonds and stripped coupons under Code Section 1286.
 
    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
 
                                       90
<PAGE>
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, 31%
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.
 
                                       91
<PAGE>
    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.
 
    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.
 
                                       92
<PAGE>
    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");
 
        (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
 
                                       93
<PAGE>
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 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.
 
                                       94

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-Related Restrictions on Transfer of Residual
Certificates--Disqualified Organizations."
 
    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
 
    Standard Certificates which are not rated, as discussed below under "Rating"
will  not constitute "mortgage related securities" for purposes of the Secondary
Mortgage  Market  Enhancement  Act  of  1984  (the  "Enhancement  Act").  Unless
otherwise specified in the related Prospectus Supplement, 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 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. Section  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
 
                                       95
<PAGE>
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, and  by  the National  Credit Union
Administration (with certain modifications), effective June 26, 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 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
 
                                       96
<PAGE>
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.
 
    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
Securities Incorporated,  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 four
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
rating.
