THE PRUDENTIAL HOME MORTGAGE SECURITIES COMPANY, INC. [LOGO]
 
                                     SELLER
 
               MORTGAGE PASS-THROUGH CERTIFICATES, SERIES 1996-6
         PRINCIPAL AND INTEREST PAYABLE MONTHLY, COMMENCING IN MAY 1996
                             ---------------------
 
    The  Series 1996-6  Mortgage Pass-Through  Certificates (the  "Series 1996-6
Certificates") will consist of  one class of senior  certificates (the "Class  A
Certificates")  and  one  class  of  subordinated  certificates  (the  "Class  B
Certificates"). The Class  A Certificates  are entitled to  a certain  priority,
relative  to the Class B Certificates, in right of distributions on the Mortgage
Loans. The Class A Certificates will consist of eight subclasses 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-R and  Class  A-LR Certificates.  The  Class B  Certificates will
consist of six  subclasses of Certificates  designated as the  Class B-1,  Class
B-2,  Class B-3, Class B-4, Class B-5  and Class B-6 Certificates, none of which
is offered hereby. Each subclass of Class A and Class B Certificates is referred
to herein as a "Subclass."  The Class A Certificates,  other than the Class  A-4
Certificates,  are the only Series 1996-6  Certificates being offered hereby and
are referred to herein collectively as the "Offered Certificates."
 
    The Class  A-1 and  Class A-2  Certificates are  planned amortization  class
certificates and are referred to herein as the "PAC Certificates." The Class A-3
Certificates  are targeted amortization  class certificates and  are referred to
herein as the "TAC Certificates." The  Class A-3 Certificates are also  referred
to  herein as the "Accretion Directed  Certificates." The Class A-5 Certificates
are companion  certificates  and  are  referred  to  herein  as  the  "Companion
Certificates." The Class A-4 Certificates, which are not offered hereby, will be
deemed  to consist of six components  (each, a "Component" and collectively, the
"Components" or the "Class A-4  Components"): two interest only components  (the
"Class  A-4 IO A Component" and the  "Class A-4 IO B Component"), three targeted
amortization class components (the "Class A-4  TAC A Component," the "Class  A-4
TAC  B Component" and  the "Class A-4 TAC  Accrual Component," and collectively,
the "TAC  Components")  and  a  principal only  component  (the  "Class  A-4  PO
Component"). The Class A-4 TAC A Component and the Class A-4 TAC B Component are
referred  to herein as the "Accretion Directed Components." The beneficial owner
of a Class A-4 Certificate will not have a severable interest in any  Component,
but will have an undivided interest in the entire Subclass.

    PROSPECTIVE INVESTORS  IN  THE  OFFERED  CERTIFICATES  SHOULD  CONSIDER  THE
FACTORS  DISCUSSED  UNDER  "RISK  FACTORS AND  SPECIAL  CONSIDERATIONS"  IN THIS
PROSPECTUS SUPPLEMENT ON PAGE S-22 AND IN THE PROSPECTUS ON PAGE 12.
                            ------------------------
 
    The Offered  Certificates  will  be  purchased from  the  Seller  by  Lehman
Brothers  Inc. (the "Underwriter")  and will be offered  by the Underwriter from
time to time  in negotiated transactions  or otherwise at  varying prices to  be
determined, in each case, at the time of sale.
 
    Proceeds  to  the Seller  are  expected to  be  approximately 98.04%  of the
aggregate initial principal  balance of  the Offered  Certificates plus  accrued
interest  thereon from  April 1,  1996 to  (but not  including) April  29, 1996,
before deducting expenses payable  by the Seller estimated  to be $315,000.  The
price  to  be paid  to  the Seller  for the  Offered  Certificates has  not been
allocated among  the  Subclasses  of Offered  Certificates.  See  "Underwriting"
herein.
 
    The  Offered  Certificates are  offered  when, as  and  if delivered  to and
accepted by the Underwriter, subject  to prior sale, withdrawal or  modification
of the offer without notice, the approval of counsel and other conditions. It is
expected  that the Offered Certificates will be delivered through the facilities
of The Depository Trust Company, or in the case of the Class A-R and Class  A-LR
Certificates,  at the offices  of Lehman Brothers  Inc., New York,  New York, in
each case, on or about April 29, 1996.

    The credit  enhancement  for  the Series  1996-6  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 (other
than the Class A-4 Certificates with respect  to the Class A-4 PO Component)  in
the  aggregate 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" herein.
 
    The Series 1996-6  Certificates will  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 20 or 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  servicing  of the  Mortgage Loans  will be  performed by  various servicers
identified herein (each, a "Servicer"),  including The Prudential Home  Mortgage
Company,  Inc. ("PHMC"), an  affiliate of both the  Seller and Securitized Asset
Services Corporation (in its capacity as master servicer, the "Master Servicer,"
otherwise "SASCOR"), and will be supervised by the Master Servicer. The Mortgage
Loans will be  acquired by  the Seller  on the date  of issuance  of the  Series
1996-6 Certificates from PHMC, and will have been originated by PHMC or acquired
by  PHMC from various entities (each, a  "PHMC Loan Seller"). The Mortgage Loans
not originated by PHMC were originated by  the PHMC Loan Sellers or acquired  by
the  PHMC Loan Sellers  pursuant to mortgage loan  purchase programs operated by
such PHMC Loan  Sellers. See  "Description of  the Mortgage  Loans" herein.  The
Class  A Certificates  will initially evidence  in the  aggregate an approximate
93.75% undivided interest in  the principal balance of  the Mortgage Loans.  The
remaining  approximate 6.25% undivided interest in  the principal balance of the
Mortgage Loans will be evidenced by the Class B Certificates.
 
    Distributions in respect of  interest and of 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  May 1996,  to  the
holders of Offered Certificates, as described herein.
 
    The  Class  A-4 TAC  Accrual Component  will  accrete interest  as described
herein. Holders of the  Class A-4 Certificates will  not be entitled to  current
distributions  of interest with  respect to the Class  A-4 TAC Accrual Component
until the  Cross-Over Date.  Instead, on  each Distribution  Date prior  to  the
Cross-Over Date, an amount equal to the accrued and unpaid interest on the Class
A-4  TAC  Accrual Component  will be  added to  the Component  Principal Balance
thereof and will be distributed in reduction of the Component Principal  Balance
thereof  and of  the principal balance  and Component Principal  Balances of the
Accretion Directed Certificates and Accretion Directed Components, as  described
herein    under   "Description   of   the   Certificates--Principal   (Including
Prepayments)--Allocation of Amount  to be Distributed."  The amount of  interest
accrued  on  any  Subclass  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." 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 (other than the Class A-4
Certificates)  and among the Class A-4 Components in the manner described herein
under "Description  of  the  Certificates--Principal  (Including  Prepayments)."
Distributions  to each  Subclass of Offered  Certificates will be  made pro rata
among Certificateholders of such Subclass.
 
    THE YIELD  TO MATURITY  OF THE  OFFERED CERTIFICATES  WILL BE  SENSITIVE  IN
VARYING  DEGREES  TO  THE  RATE  AND  TIMING  OF  PRINCIPAL  PAYMENTS (INCLUDING
PREPAYMENTS, WHICH MAY  BE MADE  AT ANY TIME  WITHOUT PENALTY)  ON THE  MORTGAGE
LOANS.  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. 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 FOR  INVESTORS  PURCHASING
OFFERED  CERTIFICATES AT A PREMIUM. INVESTORS PURCHASING OFFERED CERTIFICATES AT
A PREMIUM SHOULD ALSO CONSIDER THE RISK THAT A RAPID RATE OF PAYMENTS IN RESPECT
OF PRINCIPAL (INCLUDING PREPAYMENTS) ON THE  MORTGAGE LOANS COULD RESULT IN  THE
FAILURE  OF  SUCH  INVESTORS TO  FULLY  RECOVER THEIR  INITIAL  INVESTMENTS. SEE
"DESCRIPTION  OF   THE  CERTIFICATES--INTEREST"   AND  "--PRINCIPAL   (INCLUDING
PREPAYMENTS)" HEREIN AND "PREPAYMENT AND YIELD CONSIDERATIONS" HEREIN AND IN THE
PROSPECTUS.
 
    THE  WEIGHTED  AVERAGE LIFE  OF THE  COMPANION  CERTIFICATES WILL  BE HIGHLY
SENSITIVE TO THE RATE OF PREPAYMENTS ON THE MORTGAGE LOANS. AT RATES AT OR ABOVE
CERTAIN  PREPAYMENT   LEVELS,   PAYMENTS   OF   PRINCIPAL   ALLOCATED   TO   THE
 
                                                        (CONTINUED ON NEXT PAGE)

<PAGE>
(CONTINUED FROM PREVIOUS PAGE)
 
CLASS  A CERTIFICATES IN EXCESS OF AMOUNTS RESULTING FROM SUCH PREPAYMENT LEVELS
WILL BE PAID TO THE HOLDERS OF THE COMPANION CERTIFICATES PRIOR TO BEING PAID TO
THE HOLDERS OF THE TAC CERTIFICATES, THE CLASS A-4 CERTIFICATES WITH RESPECT  TO
THE  TAC COMPONENTS AND  THE PAC CERTIFICATES,  RESULTING IN A  REDUCTION IN THE
WEIGHTED AVERAGE  LIFE. AT  OR BELOW  CERTAIN PREPAYMENT  LEVELS, THE  COMPANION
CERTIFICATES  MAY RECEIVE  NO PRINCIPAL  PAYMENTS FOR  EXTENDED PERIODS  OF TIME
RESULTING IN AN  EXTENSION OF  THE WEIGHTED  AVERAGE LIFE.  SEE "PREPAYMENT  AND
YIELD CONSIDERATIONS" HEREIN.
 
    The   Offered  Certificates,  other  than  the  Class  A-R  and  Class  A-LR
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 a
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. Each  Subclass of  Offered  Certificates is  offered in  the  minimum
denominations    described   herein   under   "Summary   Information--Forms   of
Certificates; Denominations." It is intended  that the Offered Certificates  not
be  directly or indirectly held or beneficially owned in amounts lower than such
minimum denominations.
 
    There is  currently no  secondary market  for the  Offered Certificates  and
there  can be no  assurance that a secondary  market will develop  or, if such a
market 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  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) A 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 and Class A-LR Certificates" herein and "Certain Federal Income
Tax Consequences--Federal  Income  Tax  Consequences  for  REMIC  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
"Upper-Tier  REMIC" and the "Lower-Tier REMIC," respectively). As described more
fully herein and  in the  Prospectus, the  Class A-1,  Class A-2  and Class  A-3
Certificates,  the Class A-4 TAC A Component, the Class A-4 TAC B Component, the
Class A-4 TAC Accrual Component, the Class A-4 IO A Component, the Class A-4  IO
B  Component,  the  Class  A-4  PO  Component,  the  Class  A-5  and  Class  A-6
Certificates and the Class B-1, Class B-2,  Class B-3, Class B-4, Class B-5  and
Class  B-6 Certificates  will constitute  "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  AND  CLASS  A-LR
CERTIFICATEHOLDERS' REMIC TAXABLE INCOME AND  THE LIABILITY THEREON MAY  EXCEED,
AND  MAY SUBSTANTIALLY 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-4 Certificates,  represent
seven  Subclasses of  a Class,  all of which  are part  of a  separate Series of
Certificates being  offered  by the  Seller  pursuant to  the  Prospectus  dated
February  15,  1996  accompanying this  Prospectus  Supplement.  Any prospective
investor should not purchase any Offered Certificates described herein unless it
shall  have  received  the  Prospectus  and  this  Prospectus  Supplement.   The
Prospectus  shall not be considered complete without this Prospectus Supplement.
The Prospectus contains important information  regarding this offering which  is
not  contained herein, and prospective investors are urged to read, in full, the
Prospectus and this Prospectus Supplement.
                             ---------------------
 
    UNTIL JULY  23, 1996,  ALL  DEALERS EFFECTING  TRANSACTIONS IN  THE  OFFERED

Title of Securities...  Mortgage  Pass-Through   Certificates,   Series   1996-6
                        Certificates  (the "Series  1996-6 Certificates"  or the

Seller................  The Prudential  Home Mortgage  Securities Company,  Inc.
                        (the  "Seller"). The Mortgage Loans  will be sold to the
                        Seller by  The Prudential  Home Mortgage  Company,  Inc.
                        ("PHMC") and will either have been originated by PHMC or
                        acquired  by PHMC  from various entities  (each, a "PHMC
                        Loan Seller"),  which  either  originated  the  Mortgage

Servicing/Servicers...  PHMC will service approximately 86.39% (by Cut-Off  Date
                        Aggregate  Principal Balance) of  the Mortgage Loans and

                        Cut-Off   Date  Aggregate  Principal   Balance)  of  the
                        Mortgage Loans, each  pursuant to  a separate  servicing
                        agreement  (with  respect  to  Mortgage  Loans initially
                        serviced by PHMC, the  "PHMC Servicing Agreement,"  with

                        Servicer  under each Servicing Agreement with respect to
                        the related  Mortgage  Loans  will be  assigned  to  the
                        Trustee  for the benefit of the Certificateholders. Each
                        Servicing Agreement will require the related Servicer to
                        perform certain servicing functions with respect to  the
                        related  Mortgage  Loans;  however,  the  scope  of such
                        obligations may vary among  the Servicing Agreements  as
                        described  herein. Among other  things, each Servicer is
                        obligated  under   certain  circumstances   to   advance
                        delinquent  payments  of  principal  and  interest  with
                        respect to the  Mortgage Loans serviced  by it. Each  of

                        Principal Balance of such Mortgage Loan on the first day
                        of  the  preceding  month  and  (ii)  other   additional

Rating of
  Certificates........  It is  a  condition  to  the  issuance  of  the  Offered
                        Certificates  that they  shall have been  rated "AAA" by
                        Fitch Investors Service, L.P.  ("Fitch") and Standard  &
                        Poor's  ("S&P"). The  ratings of  S&P on  mortgage pass-
                        through certificates address  the likelihood of  receipt
                        by  the certificateholders of timely payment of interest
                        and the  ultimate return  of principal.  The ratings  of
                        Fitch  on mortgage pass-through certificates address the
                        likelihood of the receipt  by the certificateholders  of
                        all  distributions  of principal  and interest  to which
                        such certificateholders are entitled. The ratings by S&P
                        and Fitch are not recommendations  to buy, sell or  hold
                        such  Certificates  and may  be  subject to  revision or
                        withdrawal at any time  by the assigning rating  agency.
                        The  ratings do not  address the possibility  that, as a
                        result  of  principal   prepayments,  holders  of   such
                        Certificates may receive a lower than anticipated yield.
                        See    "--Effects    of   Prepayments    on   Investment
                        Expectations" below  and  "Ratings" in  this  Prospectus
                        Supplement.
Description of
  Certificates........  The Series 1996-6 Certificates will consist of the Class
                        A Certificates and the Class B Certificates. The Class A
                        Certificates represent a type of interest referred to in
                        the  Prospectus as "Senior Certificates" and the Class B
                        Certificates represent a type of interest referred to in
                        the Prospectus as "Subordinated Certificates." As  these
                        designations  suggest,  the  Class  A  Certificates  are
                        entitled to a certain priority, relative to the Class  B
                        Certificates,  in right of distributions on the mortgage
                        loans underlying  the  Series 1996-6  Certificates  (the
                        "Mortgage Loans"). See "--Distributions of Principal and
                        Interest" below.
                        The  Class A Certificates will initially evidence in the
                        aggregate  an   approximate  93.75%   interest  in   the
                        principal  balance of the  Mortgage Loans. The remaining
                        approximate 6.25% interest in  the principal balance  of
                        the  Mortgage  Loans will  be evidenced  by the  Class B
                        Certificates. The Class A-4

                        Certificates, which are not  offered hereby, consist  in
                        part  of the Class A-4  PO Component (as defined below),
                        The Class A-4 PO Component will evidence an interest  in
                        portions  of  the principal  balances of  Mortgage Loans
                        that have  Net Mortgage  Interest Rates,  as defined  on
                        page  S-32,  less  than  7.25%  (the  "Discount Mortgage
                        Loans"),  such   initial  interest   in  the   aggregate
                        representing   an  approximate  0.86%  interest  in  the
                        principal balance  of  the  Mortgage  Loans  (the  "Pool
                        Balance  (PO Portion)").  In addition, the  Class A-4 PO
                        Component will  represent an  approximate 2.79%  initial
                        interest  in  the  principal  balance  of  the  Discount
                        Mortgage Loans. By  virtue of the  subordination of  the
                        Class  B Certificates, it is possible that the Class A-4
                        PO Component  may  also  receive  support  from  certain
                        payments  made with respect to  the other Mortgage Loans
                        in the  Trust Estate.  The Class  A Certificates  (other
                        than  the  Class  A-4  PO  Component  of  the  Class A-4
                        Certificates) and the Class B Certificates will evidence
                        the entire remaining interest  in the principal  balance
                        of   the  Mortgage  Loans  (the  "Pool  Balance  (Non-PO
                        Portion)"). Initially, the  Class A Certificates  (other
                        than  the  Class  A-4  PO  Component  of  the  Class A-4
                        Certificates)  will   evidence  in   the  aggregate   an
                        approximate 93.70% (approximately $197,314,000)
                        undivided  interest in the  initial Pool Balance (Non-PO
                        Portion) and the Class  B Certificates will evidence  in
                        the   aggregate  an   approximate  6.30%  (approximately
                        $13,277,250) undivided  interest  in  the  initial  Pool
                        Balance  (Non-PO Portion). The relative interests in the
                        initial Pool Balance (Non-PO Portion) represented by the
                        Class A  Certificates  (other  than  the  Class  A-4  PO
                        Component of the Class A-4 Certificates) and the Class B
                        Certificates  are subject to change over time because of
                        the disproportionate allocation  of certain  unscheduled
                        principal  payments to  the Class  A Certificates (other
                        than the  Class  A-4  PO  Component  of  the  Class  A-4
                        Certificates)  for a specified period and the allocation
                        of certain losses and certain shortfalls to the Class  B
                        Certificates  prior to the allocation of such losses and
                        shortfalls to the Class  A Certificates (other than  the
                        Class  A-4 PO Component of  the Class A-4 Certificates),
                        as  discussed  in  "--Distributions  of  Principal   and
                        Interest" and "--Credit Enhancement" below.
                        The   Class  A   Certificates  will   consist  of  eight
                        subclasses designated as the Class A-1, Class A-2, Class
                        A-3, Class  A-4, Class  A-5, Class  A-6, Class  A-R  and
                        Class  A-LR Certificates. The  Class B Certificates will
                        consist of six subclasses, designated as the Class  B-1,
                        Class B-2, Class B-3, Class B-4, Class B-5 and Class B-6
                        Certificates. The Class A-4 and Class B Certificates are
                        not  offered hereby and  may be retained  or sold by the
                        Seller. The Class A  Certificates (other than the  Class
                        A-4  Certificates)  are referred  to in  this Prospectus
                        Supplement collectively as the "Offered Certificates."
                        The  Class  A-4  Certificates,  which  are  not  offered
                        hereby, will be deemed to consist of six components: two
                        interest only components (the "Class A-4 IO A Component"
                        and  the  "Class A-4  IO  B Component"),  three targeted
                        amortization class  components  (the "Class  A-4  TAC  A
                        Component,"  the  "Class A-4  TAC  B Component"  and the
                        "Class A-4 TAC Accrual Component," and collectively, the
                        "TAC Components") and  a principal  only component  (the
                        "Class  A-4 PO Component").  The initial component prin-
                        cipal balances of  the Class  A-4 TAC  A Component,  the
                        Class  A-4 TAC  B Component,  the Class  A-4 TAC Accrual
                        Component  and  the  Class  A-4  PO  Component  will  be
                        approximately  $24,144,000, $8,666,000,  $35,451,000 and
                        $1,829,414, respectively.  Each of  the Class  A-4 IO  A

                        the  Class  A-4  IO  B  Component  is  an  interest only
                        component and has  no component  principal balance.  The
                        principal  balance of the Class  A-4 Certificates at any
                        time will  equal  the  sum of  the  component  principal
                        balances of the Class A-4 TAC A Component, the Class A-4
                        TAC B Component, the Class A-4 TAC Accrual Component and
                        the  Class A-4 PO  Component. The holder  of a Class A-4
                        Certificate will not  have a severable  interest in  any
                        component  but will  have an  undivided interest  in the
                        entire subclass. Unless the aggregate principal  balance
                        of  the Class B  Certificates has been  reduced to zero,
                        the interest  that accrues  on the  component  principal
                        balance  of the Class A-4 TAC Accrual Component will not
                        be paid  currently as  interest to  the holders  of  the
                        Class  A-4  Certificates on  any Distribution  Date but,
                        instead, such  amounts will  be added  to the  component
                        principal   balance   of   such   component.   On   each
                        Distribution  Date,  unless   the  aggregate   principal
                        balance  of the Class B Certificates has been reduced to
                        zero, an amount equal to the accrued and unpaid interest
                        on  the  Class  A-4   TAC  Accrual  Component  will   be

                        described  under   the  heading   "Description  of   the
                        Certificates--Principal (Including Prepayments)--

                        The Class  A-1 and  Class A-2  Certificates are  planned
                        amortization  class certificates (referred  to herein as
                        the  "PAC  Certificates")  because,  based  on   certain
                        assumptions  described in  the second  paragraph on page
                        S-72, if prepayments on the Mortgage Loans occur at  any
                        CONSTANT rate between approximately 100% SPA (as defined
                        herein  under "Prepayment and Yield Considerations") and
                        approximately  600%  SPA,  it  is  expected  that  their
                        principal  balances would be  reduced to the percentages
                        of   their   initial   principal   balances   for   each
                        Distribution  Date indicated in  the tables beginning on
                        page S-42.  The  Class  A-3  Certificates  are  targeted
                        amortization  class certificates (referred  to herein as
                        the  "TAC  Certificates")  and  the  Class  A-4  TAC   A
                        Component,  the Class A-4 TAC  B Component and the Class
                        A-4 TAC Accrual  Component are  TAC Components  because,
                        based  on  certain assumptions  described in  the second
                        paragraph on page S-72,  at a constant prepayment  level
                        of  approximately 250%  SPA, it  is expected  that their
                        principal balance or component principal balances  would
                        be reduced to the percentages of their initial principal
                        balance  or component principal balance indicated in the
                        tables beginning  on page  S-42. HOWEVER,  IT IS  HIGHLY
                        UNLIKELY  THAT  PRINCIPAL  PREPAYMENTS  ON  THE MORTGAGE
                        LOANS WILL  OCCUR  AT  ANY CONSTANT  RATE  OR  THAT  THE
                        MORTGAGE  LOANS WILL PREPAY AT  THE SAME RATE. The Class
                        A-5 Certificates are companion certificates (referred to
                        herein as the "Companion Certificates") because payments
                        of principal allocated  to the Class  A Certificates  in
                        excess  of  amounts  resulting  from  certain prepayment
                        levels  will  be  paid  first  to  the  holders  of  the
                        Companion Certificates, for so long as such Certificates
                        remain  outstanding, prior to being  paid to the holders
                        of the TAC Certificates, the Class A-4 Certificates with
                        respect to the TAC Components and the PAC  Certificates.

                        issued in book-entry form, through the facilities of The

                        "Underwriting   of   the   Mortgage   Loans--PHMC   Loan

                        Approximately 0.54% (by Cut-Off Date Aggregate Principal
                        Balance)  of the Mortgage Loans (the "Pool Certification
                        Underwritten Loans") will have  been reviewed by  United
                        Guaranty  Residential  Insurance  Company  ("UGRIC")  to
                        ensure  compliance  with   its  credit,  appraisal   and
                        underwriting   standards.  Neither   the  Series  1996-6
                        Certificates nor  the  Mortgage  Loans  are  insured  or
                        guaranteed under a mortgage pool insurance policy issued
                        by UGRIC. The Pool Certification Underwritten Loans were
                        evaluated  by PHMC using enhanced credit scoring ("ECS")
                        as described  in  the Prospectus  under  "PHMC--Mortgage
                        Loan  Underwriting" and, based on the ECS scores of such
                        Mortgage  Loans,  some  of  such  Mortgage  Loans   were
                        re-underwritten by PHMC. The remaining approximate 3.35%
                        (by  Cut-Off  Date Aggregate  Principal Balance)  of the
                        Mortgage Loans (the "Bulk Purchase Underwritten  Loans")
                        were  purchased  by  PHMC  from one  or  more  PHMC Loan
                        Sellers  and   were  underwritten   using   underwriting
                        standards   which  may  vary  from  PHMC's  underwriting
                        standards. However, PHMC has  in each case reviewed  the
                        underwriting  standards applied and determined that such
                        variances  did   not  depart   materially  from   PHMC's
                        underwriting standards. See "Description of the Mortgage
                        Loans--Mortgage    Underwriting   Standards"   in   this

                        INTEREST DISTRIBUTIONS.  The amount of interest to which
                        holders of each subclass of Offered Certificates will be
                        entitled   each  month   is  calculated   based  on  the
                        outstanding principal balance of such subclass as of the
                        related Distribution  Date.  Interest will  accrue  each
                        month  on each such subclass  according to the following
                        formula:  1/12th  of  the  Pass-Through  Rate  for  such
                        subclass multiplied by the outstanding principal balance
                        of  such subclass  as of the  related Distribution Date.
                        The "Pass-Through  Rate" for  each subclass  of  Offered
                        Certificates is the percentage set forth on the cover of
                        this Prospectus Supplement.
                        Interest  will accrue on the Class A-4 Certificates each
                        month in  an amount  equal to  the sum  of the  interest
                        accrued  on the Class A-4 TAC A Component, the Class A-4
                        TAC B Component,  the Class A-4  TAC Accrual  Component,
                        the  Class A-4  IO A  Component and  the Class  A-4 IO B
                        Component. Interest will accrue on  the Class A-4 TAC  A
                        Component,  the Class A-4 TAC  B Component and the Class
                        A-4 TAC Accrual Component at  the rate of 1/12th of  the
                        Component  Rate  for such  component on  the outstanding
                        component principal balance of such component.  Interest
                        will  accrue on the Class A-4 IO A Component at the rate
                        of 1/12th of  the Component Rate  for such component  on
                        the  notional  amount for  such component.  The notional
                        amount for the Class A-4 IO  A Component on any date  is
                        equal to the product of (i) (a) the excess of 7.25% over
                        the  weighted average  of the pass-through  rates of the
                        Class A-1 Certificates  and the  Class A-2  Certificates
                        divided  by (b) 7.25% and (ii)  the sum of the principal
                        balances of the Class A-1 Certificates and the Class A-2
                        Certificates. The "Component Rate" for each of the Class
                        A-4 Components (other  than the Class  A-4 PO  Component
                        and  the Class  A-4 IO  B Component)  is 7.25%. Interest
                        will accrue on the Class A-4 IO B Component as described
                        on page S-30.
                        Holders of each subclass of Certificates, other than the
                        Class A-4 Certificates with respect to the Class A-4 TAC
                        Accrual Component and the  Class A-4 PO Component,  will
                        be entitled to receive distributions of interest on each
                        Distribution Date. Holders of the Class A-4 Certificates
                        with respect to the Class A-4 TAC Accrual Component will
                        not  be  entitled to  receive distributions  of interest
                        until the  aggregate principal  balance of  the Class  B
                        Certificates  has been reduced to zero. See "Description

                        a percentage  (the "Class  A Percentage")  of  scheduled
                        payments  of principal on each  Mortgage Loan and (ii) a

                        of the holders  of the Class  A 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  B  Certificates)

                        thereof has  been reduced  to  zero, of  certain  losses
                        resulting  from  the liquidation  of  defaulted Mortgage
                        Loans or  the  bankruptcy  of mortgagors  prior  to  the

                        respect  to the Class A-4 PO Component). This allocation
                        has the effect of  accelerating the amortization of  the
                        Class   A  Certificates   (other  than   the  Class  A-4
                        Certificates with respect to the Class A-4 PO Component)
                        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 interests  in  the principal

                        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 B Certificates
                        (which aggregate  balance is  expected initially  to  be
                        approximately  $13,277,250)  has been  reduced  to zero.
                        Such losses will  be allocated among  the subclasses  of
                        Class  B Certificates  in reverse  numerical order (that
                        is, to the Class B-6,  Class B-5, Class B-4, Class  B-3,
                        Class B-2 and Class B-1 Certificates, respectively).
                        With  respect to any Distribution Date subsequent to the
                        first Distribution Date, the availability of the  credit
                        enhancement provided by the Class B Certificates will be
                        affected by the prior reduction of the principal balance
                        of  the Class B Certificates. Reduction of the principal
                        balance of 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  spe-
                        cial  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 Certificates.
                        As  of  the  date  of  issuance  of  the  Series  1996-6
                        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  will  be  approximately  1.01%,  2.00% and

                        Principal  Balance of the  Mortgage Loans (approximately
                        $2,143,632, $4,248,413 and  $100,000, respectively).  If
                        losses  due  to  special  hazards,  fraud  or bankruptcy

                        zero, (a)  the  principal  portion of  any  such  excess
                        losses with respect to the Mortgage Loans will generally
                        be  shared  pro rata  by  (i) the  Class  A Certificates
                        (other than the Class  A-4 Certificates with respect  to
                        the Class A-4 PO Component) and the Class B Certificates
                        and (ii) to the extent such losses arise with respect to
                        Discount  Mortgage Loans, the Class  A-4 PO Component of
                        the Class A-4  Certificates, in each  case according  to
                        their  respective interests  in such  Mortgage Loans and
                        (b) the interest portion of any such losses with respect
                        to the Mortgage Loans will generally be shared pro  rata
                        by  the Class A and Class  B Certificates based on their
                        respective interest accrual amounts. After the principal
                        balance of the Class B Certificates has been reduced  to
                        zero,  the principal  portion of all  losses (other than
                        the portion attributable to  the Class A-4 PO  Component
                        of the Class A-4 Certificates, if any) will be allocated

                        Component). To the extent such losses arise with respect
                        to  Discount Mortgage Loans, such  losses will be shared
                        among the  Class  A  Certificates,  according  to  their
                        respective  interests  in such  Mortgage Loans,  and the
                        interest portion of  such losses  will be  borne by  the
                        Class  A  Certificates.  The  principal  portion  of any
                        losses borne  by the  Class A  Certificates (other  than
                        losses  borne by the Class A-4 Certificates with respect
                        to the Class A-4 PO  Component) will be shared pro  rata
                        by the subclasses of Class A Certificates based on their
                        then-outstanding  principal balances or,  in the case of
                        the   Class   A-4   Certificates,   the   sum   of   the

                        the Class  A-4  TAC  Accrual Component,  if  lower.  The
                        interest  portion of  such losses  borne by  the Class A
                        Certificates will be shared  pro rata by the  subclasses
                        of   Class  A  Certificates.  See  "Description  of  the

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.  In addition, the Class A Certificates in the
                        aggregate will be more  sensitive to prepayments on  the
                        Mortgage  Loans than the Class B Certificates due to the
                        disproportionate  allocation  of  such  prepayments   to
                        investors  in the  Class A Certificates  (other than the
                        Class A-4 Certificates with respect to the Class A-4  PO
                        Component)  then  entitled  to  principal  distributions
                        during  the   nine   years  beginning   on   the   first
                        Distribution  Date. 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
                        PREPAYMENT ASSUMPTIONS TO BE USED.
                        YIELD.   If an investor purchases an Offered Certificate
                        at an amount equal to its unpaid principal balance (that
                        is,  at  "par"), the  effective  yield to  that investor
                        (assuming that  there  are no  interest  shortfalls  and
                        assuming  the  full  return of  the  investor'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 an Offered  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.  The
                        timing  of receipt  of prepayments  may also  affect the
                        investor's actual yield. AN INVESTOR THAT PURCHASES  ANY
                        OFFERED  CERTIFICATES AT A  DISCOUNT SHOULD 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 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 SHOULD CONSIDER THE
                        RISK THAT  A RAPID  RATE OF  PRINCIPAL PAYMENTS  ON  THE
                        MORTGAGE  LOANS  COULD  RESULT IN  THE  FAILURE  OF SUCH
                        INVESTOR TO FULLY RECOVER ITS INITIAL INVESTMENT.
                        REINVESTMENT RISK.    As  stated above,  if  an  Offered
                        Certificate  is  purchased  at an  amount  equal  to its
                        unpaid  principal   balance   (that   is,   at   "par"),
                        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 investor'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 speeds on a security is the
                        change in  its  weighted  average  life.  The  "weighted
                        average  life" of an Offered  Certificate is the average

                        amount of  time that  will elapse  between the  date  of
                        issuance  of the Certificate and  the date on which each
                        dollar in  reduction of  the  principal balance  of  the
                        Certificate is distributed to the investor. Low rates of
                        prepayment  may result in the  extension of the weighted
                        average life  of  a  Certificate;  high  rates,  in  the
                        shortening of such weighted average life. In general, if
                        the  weighted average life of a Certificate purchased at
                        par is extended beyond that initially anticipated,  such
                        Certificate's  market  value may  be  adversely affected
                        even though the yield to maturity on the Certificate  is

Federal Income Tax
  Status..............  For  federal income tax purposes,  the Trust Estate will
                        consist of two real estate mortgage investment  conduits
                        (the  "Upper-Tier  REMIC"  and  the  "Lower-Tier REMIC,"
                        respectively). The Class  A-1, Class A-2  and Class  A-3
                        Certificates,  the Class A-4 TAC  A Component, the Class
                        A-4  TAC  B  Component,   the  Class  A-4  TAC   Accrual
                        Component,  the Class A-4 IO  A Component, the Class A-4
                        IO B Component,  the Class A-4  PO Component, the  Class
                        A-5  and Class A-6 Certificates and the Class B-1, Class
                        B-2, Class  B-3,  Class B-4,  Class  B-5 and  Class  B-6
                        Certificates  will constitute "regular interests" in the
                        Upper-Tier REMIC  and  the  Class  A-R  and  Class  A-LR
                        Certificates  will constitute the "residual interest" in
                        the Upper-Tier REMIC and Lower-Tier REMIC, respectively.
                        The Class A-1, Class A-2, Class A-3, Class A-5 and Class
                        A-6 Certificates (the "Regular Certificates")  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  and
                        Class  A-5  Certificates  will be  issued  with original
                        issue discount in an amount equal to the excess of their
                        initial principal balances (plus  four days of  interest
                        at  the Pass-Through Rate thereon) over their respective
                        issue prices (including accrued interest). In  addition,
                        it  is  anticipated that  the  Class A-2  and  Class A-3
                        Certificates will be  issued at a  premium and that  the
                        Class  A-6 Certificates  will be issued  with DE MINIMIS
                        original issue discount for federal income tax purposes.
                        Holders of  the Class  A-R and  Class A-LR  Certificates
                        will  be required to include  the taxable income or loss
                        of  the   Upper-Tier   REMIC   and   Lower-Tier   REMIC,
                        respectively,   in  determining  their  federal  taxable
                        incomes. 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
                        limitations  for  federal  income  tax  purposes.  AS  A
                        RESULT, THE EFFECTIVE AFTER-TAX RETURN OF THE CLASS  A-R

                        (collectively,  a "Plan"), should  carefully review with
                        its legal advisors  whether the purchase  or holding  of
                        Offered  Certificates could  give rise  to a transaction
                        prohibited or not otherwise permissible under ERISA, the
                        Code or Similar Law.  NEITHER THE CLASS A-R  CERTIFICATE

                        TRANSFERRED TO  A PLAN.  See "ERISA  Considerations"  in
                        this Prospectus Supplement and in the Prospectus.
Legal Investment......  The   Offered  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 Offered Certificates are legal investments
                        for certain entities to the extent provided in such act.
                        However,   there   are   regulatory   requirements   and
                        considerations   applicable   to   regulated   financial
                        institutions and  restrictions on  the ability  of  such
                        institutions  to  invest  in certain  types  of mortgage
                        related  securities.  Prospective   purchasers  of   the
                        Offered Certificates should consult their own legal, tax
                        and  accounting advisors in  determining the suitability
                        of and consequences to  them of the purchase,  ownership
                        and  disposition of the Offered Certificates. See "Legal

                    RISK FACTORS AND SPECIAL CONSIDERATIONS
 
GENERAL
 
    The  rate  of distributions  in reduction  of the  principal balance  of any
Subclass of  Offered  Certificates, the  aggregate  amount of  distributions  of
principal  and interest on any Subclass of Offered Certificates and the yield to
maturity of any Subclass of Offered Certificates 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  for breaches  of
representations  and warranties and optional purchase  by the Master Servicer of
all of  the Mortgage  Loans in  connection  with the  termination of  the  Trust
Estate.  See "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.
 
    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.
 
    An investor that  purchases any  Offered Certificates at  a discount  should
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 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.   See  "Prepayment  and   Yield
Considerations" herein.
 
BOOK-ENTRY SYSTEM FOR CERTAIN SUBCLASSES OF CLASS A CERTIFICATES
 
    Since transactions in the Offered Certificates (other than the Class A-R and
Class  A-LR  Certificates)  (the  "Book-Entry  Certificates")  generally  can be
effected only through DTC, DTC  Participants and Indirect DTC Participants,  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 Master Servicer, or a  paying
agent  on behalf  of the  Master Servicer,  to Cede,  as nominee  for DTC. Also,
issuance of  the  Book-Entry Certificates  in  book-entry form  may  reduce  the
liquidity  thereof in  any secondary  trading market  that may  develop therefor
because investors may be unwilling to purchase securities for which they  cannot
obtain   delivery   of   physical   certificates.   See   "Description   of  the
Certificates--Book-Entry Form" herein.
 
RECENT DEVELOPMENTS
 
    The Seller, SASCOR  and PHMC 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 PHMC  substantially all of  its assets and  businesses, other than
certain mortgage loans  and PHMC'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  PHMC ("SASI"),  including the  Mortgage Loans  in the  Trust Estate
serviced
 
                                      S-22
<PAGE>
by PHMC, and certain other mortgage servicing rights (all such servicing  rights
collectively,  the "Retained Servicing"). It is the present intention of PHMC 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  addition, pursuant  to the  Sale Agreement,
Norwest Bank  will also,  on the  Sale Date,  acquire substantially  all of  the
assets  and  succeed  to  all  of  the  obligations  of  SASCOR,  including  the
obligations of  SASCOR, as  Master  Servicer, under  the Pooling  and  Servicing
Agreement.
 
    In  order to assure the performance  of PHMC's obligations as servicer under
the PHMC Servicing  Agreement as  well as  under certain  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
PHMC  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 "Mortgage Loan Servicing Agreement") and
under each other agreement  pursuant to which  PHMC 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 Mortgage Loan Servicing Agreement"), PHMC, Prudential Insurance
and  Norwest intend  to enter into  a subservicing  agreement (the "Subservicing
Agreement"), pursuant  to which  PHMC  will delegate  to Norwest  Mortgage,  and
Norwest  Mortgage will agree to perform, all of PHMC's duties and obligations as
mortgage loan servicer under the PHMC Servicing Agreement and each Mortgage Loan
Servicing Agreement  and Other  Mortgage Loan  Servicing Agreement,  other  than
PHMC's  duties with respect to the administration and disposition of real estate
acquired upon foreclosure, which latter duties will remain the responsibility of
PHMC with the particular functions to  be delegated by PHMC to Prudential  Asset
Recovery,  Inc., an affiliate  of the Seller, PHMC,  SASCOR, SASI and Prudential
Insurance, or other third party contractors.  With respect to the Series  1996-6
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 PHMC Servicing Agreement and foreclosure or
other  realization  activities  in  connection  with  defaulted  Mortgage  Loans
serviced under the PHMC Servicing Agreement.
 
    Under the Subservicing Agreement, Norwest Mortgage will be obligated to make
any principal and interest or other advances  required to be made by PHMC  under
the  PHMC  Servicing Agreement  as well  as under  each Mortgage  Loan Servicing
Agreement  or  Other  Mortgage  Loan  Servicing  Agreement,  provided  that  the
aggregate  unreimbursed amount of such advances at any time does not exceed $100
million. PHMC will be obligated to reimburse Norwest Mortgage for the amount  of
any such advances, plus interest, from its own funds. PHMC will remain obligated
under  the PHMC Servicing  Agreement and each  Mortgage Loan Servicing Agreement
and Other Mortgage Loan 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, PHMC will  enter into a  Loan
Agreement with Prudential Funding Corporation, an affiliate of the Seller, PHMC,
SASCOR,  SASI and  Prudential Insurance  ("Funding"), pursuant  to which Funding
will provide PHMC with a committed  borrowing line (the "Loan Facility") in  the
amount  of $40 million, for the sole  purpose of supporting advances required of
PHMC under the PHMC Servicing Agreement and Mortgage Loan Servicing  Agreements.
Although  PHMC  expects  that  the  combination  of  Norwest  Mortgage's advance
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 mechanism  will be sufficient, or  that after the Sale  Date
PHMC  will have  sufficient other assets,  to ensure that  all required advances
will be made.
 
    PHMC will pay Norwest  Mortgage a portion  of PHMC's servicing  compensation
under  the  PHMC  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 PHMC,  at its
option, provided that PHMC 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  PHMC, from  time to  time,  with
respect  to any Mortgage  Loans as to  which PHMC arranges  to sell the Retained
Servicing.
 
    The Subservicing Agreement will provide for the delegation of  substantially
all  of PHMC's duties and obligations  under the PHMC Servicing Agreement. While
the   PHMC    Servicing   Agreement    provides    that   PHMC    will    remain
 
                                      S-23
<PAGE>
liable  for its obligations  thereunder until the  related Retained Servicing is
transferred in the manner permitted thereby,  from and after the Sale Date  PHMC
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 PHMC pursuant
to an agreement under which PHMC is required to repurchase or substitute for any
such Mortgage Loan  so repurchased or  substituted for by  the Seller.  Although
after  the Sale  Date PHMC  will continue  to own  the Retained  Servicing, PHMC
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 PHMC 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 serviced  under the PHMC
Servicing Agreement  and subserviced  pursuant  to the  Subservicing  Agreement,
Prudential  Insurance will  agree in the  Subservicing Agreement  to provide the
funds to repurchase such Mortgage Loan.
 
    According to information provided by Norwest Mortgage, at December 31, 1995,
Norwest Mortgage  was  the  nation's  largest  mortgage  originator  and  had  a
servicing  portfolio  of  more  than $107  billion.  In  1995,  Norwest Mortgage
originated over $33 billion of residential mortgage loans. Headquartered in  Des
Moines,  Iowa, Norwest Mortgage has more than 700 loan production offices in all
50 states.  While derived  from sources  believed to  be reliable,  neither  the
Seller,  PHMC, SASCOR nor  the Underwriter makes  any representation or warranty
regarding the  accuracy or  completeness of  the information  contained in  this
paragraph.

    Each  Subclass of the Book-Entry  Certificates initially will be represented
by one 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
Definitive  Certificate representing  such person's  interest in  the Book-Entry
Certificates,  except  as   set  forth  below.   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  DTC 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.
 
    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  ("DTC
Participants")  and  to facilitate  the clearance  and settlement  of securities
transactions among  DTC Participants  through electronic  book-entries,  thereby
eliminating  the need  for physical  movement of  certificates. DTC 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 DTC  Participant,
either directly or indirectly ("Indirect DTC 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  DTC 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. DTC  Participants
and  Indirect DTC 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 DTC Participants or Indirect DTC Participants
but  desire  to purchase,  sell  or otherwise  transfer  ownership of,  or other
interests in, Book-Entry Certificates  may do so  only through DTC  Participants
and  Indirect DTC Participants. In addition,  Beneficial Owners will receive all
distributions of principal and  interest from the Master  Servicer, or a  paying
agent  on  behalf of  the Master  Servicer, through  DTC Participants.  DTC will
forward such  distributions  to  its DTC  Participants,  which  thereafter  will
forward  them  to Indirect  DTC  Participants or  Beneficial  Owners. Beneficial
Owners will  not be  recognized by  the Trustee,  the Trust  Administrator,  the
Master
 
                                      S-25
<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
DTC Participants.
 
    Because DTC can only act on behalf  of DTC Participants, who in turn act  on
behalf  of  Indirect  DTC  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 Master Servicer,  or a paying agent on
behalf of the Master 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 DTC  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 DTC  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 DTC
Participants whose  holdings of  Book-Entry  Certificates evidence  such  Voting
Interests authorize divergent action.
 
    Neither  the Seller,  the Master Servicer,  the Trust  Administrator 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, a DTC Participant or an Indirect DTC Participant
in  whose  name  Book-Entry  Certificates are  registered,  the  ability  of the
Beneficial Owners of such Book-Entry Certificates to obtain timely payment  and,
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.
 
    The 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  Master Servicer  advises the  Trust Administrator 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 Master Servicer is unable to  locate a qualified successor, (ii) the  Master
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  Master
Servicer   under  the   Pooling  and  Servicing   Agreement,  Beneficial  Owners
representing not  less than  51%  of the  Voting  Interests of  the  outstanding
Book-Entry  Certificates advise the Trust Administrator 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 Trust  Administrator will  be required to  notify all  Beneficial
Owners  through DTC Participants of the availability of Definitive Certificates.
Upon surrender by DTC of  the physical certificates representing the  Book-Entry
Certificates   and  receipt  of  instructions  for  re-registration,  the  Trust
Administrator  will   reissue   the  Book-Entry   Certificates   as   Definitive
Certificates  to Beneficial  Owners. The procedures  relating to  payment on and
transfer of  Certificates  initially  issued  as  Definitive  Certificates  will
thereafter  apply to  those Book-Entry Certificates  that have  been reissued as
Definitive Certificates.
 
DISTRIBUTIONS
 
    Distributions of interest and in  reduction of principal balance to  holders
of  each Subclass of Class  A and Class B Certificates  will be made monthly, to
the extent of each Subclass's entitlement thereto, on the 25th day of each month
or, if such day is not a business  day, on the succeeding business day (each,  a
"Distribution  Date"),  beginning  in May  1996.  With  respect to  the  Class A
Certificates (other than the  Class A-4 Certificates with  respect to the  Class
A-4  PO  Component), such  distributions will  be  made, to  the extent  of each
Subclass's entitlement thereto,  in an  aggregate amount  equal to  the Class  A
Non-PO  Distribution Amount. With respect  to the Class A-4  PO Component of the
Class A-4 Certificates, such  distributions will be made,  to the extent of  the
Class  A-4 PO Component's  entitlement thereto, on each  Distribution Date in an
amount equal to the Class A-4  PO Component Principal Distribution Amount  after
all  amounts in  respect of interest  due on  the Class A  Certificates for such
Distribution Date including all previously
 
                                      S-26
<PAGE>
unpaid Class A Subclass Interest Shortfall Amounts with respect to any  Subclass
of   Class   A   Certificates  have   been   paid.  See   "Description   of  the
Certificates--Interest" herein.  The  "Remittance  Date"  with  respect  to  any
Distribution  Date will be the 18th  day of each month, or  if such day is not a
business day, the preceding business day. The "Determination Date" with  respect
to  each Distribution Date will be the 17th day of each month, or if each 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 any Certificate  will
only  be made upon presentation and surrender  of such Certificate at the office
or agency appointed by  the Trust Administrator and  specified in the notice  of
final distribution in respect of such 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 (net of related  Servicing Fees) on or  in respect of the Mortgage
Loans received by the Master Servicer, including without limitation any  related
insurance  proceeds and the proceeds of any  purchase of a related Mortgage Loan
for breach of a representation or warranty  or the sale of a Mortgaged  Property
by a Servicer in connection with the liquidation of the related Mortgage Loan on
or  prior to the  Remittance Date in  the month in  which such Distribution Date
occurs, plus (i) all Periodic Advances made by any Servicer, the Master Servicer
or the Trust Administrator and (ii)  all other amounts (including any  insurance
proceeds)  placed in the Master Servicer Custodial Account by any Servicer on or
before the  Remittance  Date  or  by  the  Master  Servicer  on  or  before  the
Distribution Date pursuant to the Pooling and Servicing Agreement, but excluding
the following:
 
    (a)  amounts received as  late payments of  principal or interest respecting
which one or more unreimbursed Periodic Advances has been made;
 
    (b) to the  extent permitted by  the Pooling and  Servicing Agreement,  that
portion  of Liquidation Proceeds with respect to a Mortgage Loan that represents
any unreimbursed Periodic Advances of such Servicer;
 
    (c) those portions of each payment of interest on a particular Mortgage Loan
which represent  (i) the  applicable Servicing  Fee as  adjusted in  respect  of
Prepayment   Interest  Shortfalls  and,   if  applicable,  Curtailment  Interest
Shortfalls as described under "Description of the Certificates--Interest"  below
and (ii) the Master Servicing Fee;
 
    (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 partial principal prepayments
on Mortgage Loans serviced under an  Other Servicing Agreement and all  proceeds
of  any Mortgage  Loans, or  property acquired  in respect  thereof, liquidated,
purchased or repurchased pursuant to the Pooling and Servicing Agreement  (other
than  Partial Liquidation Proceeds with respect to Mortgage Loans serviced under
the PHMC Servicing Agreement), received by  Servicers or the Master Servicer  on
or  after the Due  Date occurring in  the month in  which such Distribution Date
occurs, and all principal prepayments in full, partial principal prepayments and
Partial Liquidation Proceeds on Mortgage Loans serviced under the PHMC Servicing
Agreement, received by PHMC 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  or  proceeds of  any Mortgaged  Property  held by  the Trust  Estate which
represents any  unpaid Servicing  Fee  or Master  Servicing  Fee to  which  such
Servicer  or the Master Servicer, respectively,  is entitled, and the portion of
net Liquidation Proceeds  used to reimburse  any unreimbursed Periodic  Advances
made by the Master Servicer or the Trust Administrator;
 
    (g)  all amounts  representing certain  expenses reimbursable  to the Master
Servicer and other amounts  permitted to be retained  by the Master Servicer  or
withdrawn  by the  Master Servicer  from the  Master Servicer  Custodial Account
pursuant to the Pooling and Servicing Agreement;
 
                                      S-27
<PAGE>
    (h) reinvestment earnings on  payments received in  respect of the  Mortgage
Loans or on other amounts on deposit in the Master Servicer Custodial Account;
 
     (i) proceeds received in connection with the liquidation of a Mortgage Loan
serviced  under an Other Servicing Agreement in  any month prior to the month in
which such Mortgage Loan becomes a Liquidated Loan (other than any such proceeds
with respect to a Mortgage Loan that became a Liquidated Loan in the month prior
to the month in which such Distribution Date occurs);
 
     (j) Net Foreclosure Profits; and
 
    (k) the  amount  of  any  recoveries  in  respect  of  principal  which  had
previously  been allocated as a loss to one or more Classes or Subclasses of the
Certificates.
 
    Each Servicer  is  required to  deposit  in the  Master  Servicer  Custodial
Account  on the Remittance Date certain amounts in respect of the Mortgage Loans
as set forth herein under "Servicing of the Mortgage Loans--Custodial Accounts."
The Master Servicer is required to remit to the Trust Administrator on or before
the Distribution Date any  payments constituting part  of the Pool  Distribution
Amount  that are received by the Master Servicer or are required to be made with
the Master Servicer's own funds. Except as described below under "Description of
the Certificates--Periodic Advances"  the Master  Servicer is  not obligated  to
remit  to the Trust Administrator any amounts  which a Servicer was required but
failed to deposit in the Master Servicer Custodial Account.
 
    On each Distribution Date,  the Pool Distribution  Amount will be  allocated
among  the Classes or Subclasses of  Certificates and distributed to the holders
thereof of  record  as  of  the  related  Record  Date  as  follows  (the  "Pool
Distribution Amount Allocation"):
 
    FIRST,  to the Subclasses of  Class A Certificates, pro  rata based on their
respective Class A Subclass Interest Accrual Amounts, in an aggregate amount  up
to the sum of the Class A Subclass Interest Accrual Amounts with respect to such
Distribution  Date; provided, that prior to the Cross-Over Date, an amount equal
to the amount that  would otherwise be distributable  in respect of interest  to
the  Class A-4  Certificates by  virtue of the  Class A-4  TAC Accrual Component
pursuant to  this provision  will be  distributed in  reduction of  the Class  A
Subclass  Principal Balance  and Component  Principal Balances  of the Accretion
Directed Certificates, the Accretion Directed  Components and the Class A-4  TAC
Accrual   Component   as   set  forth   below   under   "--Principal  (Including
Prepayments)-- Allocation of Amount to be Distributed;"
 
    SECOND, to the Subclasses of Class  A Certificates, pro rata based on  their
respective  unpaid Class A Subclass Interest  Shortfall Amounts, in an aggregate
amount up  to  the  sum of  the  previously  unpaid Class  A  Subclass  Interest
Shortfall  Amounts; provided, that prior to the Cross-Over Date, an amount equal
to the  amount that  would otherwise  be distributable  in respect  of  interest
shortfalls  to the Class A-4 Certificates by virtue of the Class A-4 TAC Accrual
Component pursuant to  this provision will  be distributed in  reduction of  the
Class  A  Subclass Principal  Balance and  Component  Principal Balances  of the
Accretion Directed Certificates, the Accretion Directed Components and the Class
A-4 TAC  Accrual Component  as  set forth  below under  "--Principal  (Including
Prepayments)-- Allocation of Amount to be Distributed;"
 
    THIRD,  concurrently, to the Class A  Certificates (other than the Class A-4
Certificates with  respect to  the Class  A-4 PO  Component) and  the Class  A-4
Certificates  with respect to the Class A-4 PO Component, pro rata, based on the
Class A Non-PO Optimal Principal Amount  and the Class A-4 PO Component  Optimal
Principal  Amount, (A) to the Subclasses of Class A Certificates (other than the
Class A-4  Certificates with  respect to  the  Class A-4  PO Component),  in  an
aggregate  amount  up  to the  Class  A  Non-PO 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"  and (B) to the Class A-4
Certificates with respect to the Class A-4  PO Component in an amount up to  the
Class A-4 PO Component Optimal Principal Amount;
 
    FOURTH,  to the  Class A-4  Certificates with  respect to  the Class  A-4 PO
Component in an amount  up to the  Class A-4 PO  Component Deferred Amount,  but
only  from amounts otherwise distributable (without  regard to this priority) to
the subclasses of Class B Certificates pursuant to priority FIFTH clause (C)  of
this Pool Distribution Amount Allocation; and
 
                                      S-28
<PAGE>
    FIFTH,  sequentially, to  the Class  B-1, Class  B-2, Class  B-3, Class B-4,
Class B-5 and Class  B-6 Certificates so that  each such subclass shall  receive
(A) an amount up to its Class B Subclass Interest Accrual Amount with respect to
such Distribution Date, (B) then, an amount up to its previously unpaid interest
shortfall amount and (C) finally, an amount up to its subclass optimal principal
amount  before  any subclasses  of Class  B  Certificates with  higher numerical
designations receive any payments in respect of interest or principal; provided,
however, that the amount  distributable pursuant to  this priority FIFTH  clause
(C)  to any subclasses of Class B Certificates will be reduced by the amount, if
any, otherwise distributable as principal hereunder used to pay the Class A-4 PO
Component Deferred Amount in accordance with priority FOURTH.
 
    The "Class A Non-PO Distribution Amount"  for any Distribution Date will  be
equal to the sum of the amounts distributed in accordance with priorities FIRST,
SECOND and THIRD clause (A) of the Pool Distribution Amount Allocation set forth
above.
 
    The undivided percentage interest (the "Percentage Interest") represented by
any  Offered Certificate of a Subclass in distributions to such Subclass will be
equal to the percentage  obtained by dividing the  initial principal balance  of
such  Certificate by the aggregate initial principal balance of all Certificates
of such Subclass.
 
INTEREST
 
    The amount  of  interest  that will  accrue  on  each Subclass  of  Class  A
Certificates  during  each month,  after taking  into account  any Non-Supported
Interest Shortfalls and the interest portion of certain losses allocated to such
Subclass, is  referred to  herein  as the  "Class  A Subclass  Interest  Accrual
Amount" for such Subclass. The Class A Subclass Interest Accrual Amount for each
Subclass  of Class A  Certificates, other than the  Class A-4 Certificates, will
equal the difference between (a) 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  and (b)  the sum  of (i)  any Non-Supported  Interest
Shortfall  allocable to such  Subclass, (ii) the interest  portion of any Excess
Special  Hazard  Losses,  Excess  Fraud  Losses  and  Excess  Bankruptcy  Losses
allocable  to  such Subclass  and  (iii) the  interest  portion of  any Realized
Losses, other than  the interest portion  of any Excess  Special Hazard  Losses,
Excess  Fraud Losses and Excess Bankruptcy Losses, allocable to such Subclass on
or after the Cross-Over Date. The pass-through rate for each Subclass of Class A
Certificates (other than the Class  A-4 Certificates) (the "Pass-Through  Rate")
is the percentage set forth on the cover of this Prospectus Supplement.
 
    The  Class A Subclass Interest Accrual Amount for the Class A-4 Certificates
will equal the sum of the Component  Interest Accrual Amounts for the Class  A-4
TAC  A Component, Class  A-4 TAC B  Component, Class A-4  TAC Accrual Component,
Class A-4 IO A Component  and Class A-4 IO B  Component. The amount of  interest
that  will accrue on  each such Component  during each month,  after taking into
account any  Non-Supported  Interest  Shortfalls and  the  interest  portion  of
certain  losses  allocated  to such  Component,  is  referred to  herein  as the
"Component Interest Accrual Amount" for such Component.
 
    The Component Interest Accrual Amount for the Class A-4 TAC A Component, the
Class A-4 TAC B Component and the Class A-4 TAC Accrual Component will equal the
difference between (a) the product of (i) 1/12th of the Component Rate for  such
Component and (ii) the outstanding Component Principal Balance of such Component
and  (b) the sum of such Component's pro rata share based on interest accrued of
(i)  any  Non-Supported   Interest  Shortfall   allocable  to   the  Class   A-4
Certificates,  (ii) the  interest portion of  any Excess  Special Hazard Losses,
Excess Fraud Losses  and Excess  Bankruptcy Losses  allocable to  the Class  A-4
Certificates  and (iii) the interest portion  of any Realized Losses, other than
the interest portion of  any Excess Special Hazard  Losses, Excess Fraud  Losses
and  Excess Bankruptcy  Losses, allocable  to the  Class A-4  Certificates on or
after the Cross-Over Date.
 
    The Component Interest Accrual Amount for the Class A-4 IO A Component  will
equal the difference between (a) the product of (i) 1/12th of the Component Rate
for such Component and (ii) the Class A-4 IO A Component Notional Amount and (b)
the  sum of such Component's pro rata share based on interest accrued of (i) any
Non-Supported Interest Shortfall allocable to  the Class A-4 Certificates,  (ii)
the  interest portion of  any Excess Special Hazard  Losses, Excess Fraud Losses
and Excess Bankruptcy Losses allocable to  the Class A-4 Certificates and  (iii)
the  interest portion of any Realized Losses, other than the interest portion of
any Excess  Special Hazard  Losses, Excess  Fraud Losses  and Excess  Bankruptcy
Losses, allocable to the Class A-4 Certificates on or after the Cross-Over Date.
 
                                      S-29
<PAGE>
    The  Component Interest Accrual Amount for the Class A-4 IO B Component will
equal the  difference between  (a) the  product of  (i) 1/12  of the  difference
between  (A) the  weighted average  of the  Net Mortgage  Interest Rates  of the
Mortgage Loans that have Net Mortgage  Interest Rates (as defined on page  S-32)
greater  than 7.25% (the  "Premium Mortgage Loans")  as of the  first day of the
month preceding the month in which  the applicable Distribution Date occurs  and
(B)  7.25% and (ii) the Class A-4 IO B Component Notional Amount and (b) the sum
of such  Component's pro  rata share  based  upon interest  accrued of  (i)  any
Non-Supported  Interest Shortfall allocable to  the Class A-4 Certificates, (ii)
the interest portion of  any Excess Special Hazard  Losses, Excess Fraud  Losses
and  Excess Bankruptcy Losses allocable to  the Class A-4 Certificates and (iii)
the interest portion of any Realized Losses, other than the interest portion  of
any  Excess Special  Hazard Losses,  Excess Fraud  Losses and  Excess Bankruptcy
Losses, allocable to the Class A-4 Certificates on or after the Cross-Over Date.
 
    The "Component Rate" for  each of the Class  A-4 Components (other than  the
Class A-4 IO B Component and the Class A-4 PO Component) is 7.25%.
 
    The  Class A-4 IO A  Component of the Class  A-4 Certificates is an interest
only Component  and has  no principal  balance. The  "Class A-4  IO A  Component
Notional  Amount" with respect  to each Distribution  Date will be  equal to the
product of  (i)  (a) the  excess  of 7.25%  over  the weighted  average  of  the
Pass-Through  Rates of the Class  A-1 and Class A-2  Certificates divided by (b)
7.25% and (ii) the sum of the  Class A Subclass Principal Balances of the  Class
A-1  and Class  A-2 Certificates. Accordingly,  any distributions  in respect of
principal made to, or losses in respect of principal allocated in reduction  of,
the  Class  A  Subclass  Principal  Balance  of  the  Class  A-1  or  Class  A-2
Certificates will result in a reduction in the Class A-4 IO A Component Notional
Amount. See "--Principal (Including Prepayments)" and "--Subordination of  Class
B  Certificates--Allocation  of Losses"  herein. The  Class  A-4 IO  A Component
Notional  Amount  with  respect   to  the  first   Distribution  Date  will   be
approximately $8,625,000.
 
    The  Class A-4 IO B  Component of the Class  A-4 Certificates is an interest
only Component  and has  no principal  balance. The  "Class A-4  IO B  Component
Notional  Amount" with respect  to each Distribution  Date will be  equal to the
aggregate Scheduled Principal Balance of the  Premium Mortgage Loans as of  such
Distribution  Date. The Class A-4 IO B Component Notional Amount with respect to
the first Distribution Date will be approximately $146,859,946.
 
    No interest will  accrue on  the Class  A-4 PO  Component of  the Class  A-4
Certificates.
 
    The  amount  of  interest that  will  accrue  on each  Subclass  of  Class B
Certificates during  each month,  after taking  into account  any  Non-Supported
Interest Shortfalls and the interest portion of certain losses allocated to such
Subclass,  is  referred to  herein  as the  "Class  B Subclass  Interest Accrual
Amount." The Class B Subclass Interest Accrual Amount will equal the  difference
between  (a) the product of (i) 1/12th of 7.25% and (ii) the outstanding Class B
Subclass Principal Balance  and (b) the  sum of (i)  any Non-Supported  Interest
Shortfall allocable to such Subclass and (ii) the interest portion of any Excess
Special  Hazard  Losses,  Excess  Fraud  Losses  and  Excess  Bankruptcy  Losses
allocable to such Subclass.
 
    The  "Class  A  Subclass  Principal  Balance"  of  a  Subclass  of  Class  A
Certificates  (other than  the Class A-4  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's  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 (other than the  Class A-4 Certificates with  respect to the  Class
A-4 PO Component) in the manner described herein under "--Subordination of Class
B  Certificates--Allocation of Losses."  After the Cross-Over  Date, the Class A
Subclass Principal Balance of a Subclass may be subject to further reduction  in
an  amount equal to  such Subclass's pro  rata share of  the difference, if any,
between (a) the Class A Non-PO  Principal Balance as of such Determination  Date
without regard to this provision and (b) the difference between (i) the Adjusted
Pool  Amount  for the  preceding Distribution  Date and  (ii) the  Adjusted Pool
Amount (PO Portion) 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  (other than  the Class  A-4
Certificates),  the Class A-4 TAC A Component, the Class A-4 TAC B Component and
the Class A-4 TAC

Principal  Balances or Component Principal Balances or, in the case of the Class
A-4 TAC Accrual Component,  its initial Component  Principal Balance, if  lower,
immediately prior to the preceding Distribution Date.
 
    The  Class A Subclass Principal Balance of  the Class A-4 Certificates as of
any Determination Date will  be the sum of  the Component Principal Balances  of
the  Class A-4 TAC A Component, the Class A-4 TAC B Component, the Class A-4 TAC
Accrual Component and the Class A-4 PO Component.
 
    The "Component Principal Balance"  of each Component  (other than the  Class
A-4  PO Component) as of any Determination Date will be the principal balance of
such Component on the date of initial issuance of the Class A Certificates plus,
in the case of the  Class A-4 TAC Accrual Component,  the Class A-4 TAC  Accrual
Component  Distribution  Amount,  as  described  under  "--Principal  (Including
Prepayments)" below, previously added to the Component Principal Balance of  the
Class  A-4 TAC Accrual Component, less (i) all amounts previously distributed to
holders of the Class A-4 Certificates  in reduction of the principal balance  of
such Component and (ii) such Component's pro rata share of the principal portion
of  Excess  Special Hazard  Losses, Excess  Fraud  Losses and  Excess Bankruptcy
Losses previously allocated to  the Class A Certificates  (other than the  Class
A-4  Certificates with  respect to  the Class  A-4 PO  Component) in  the manner
described herein under "--Subordination  of Class B Certificates--Allocation  of
Losses."  After the  Cross-Over Date,  the Component  Principal Balance  of each
Component may  be  subject to  further  reduction in  an  amount equal  to  such
Component's  pro rata share of  the difference, if any,  between (a) the Class A
Non-PO Principal Balance as  of such Determination Date  without regard to  this
provision  and (b) the difference  between (i) the Adjusted  Pool Amount for the
preceding Distribution Date and (ii) the  Adjusted Pool Amount (PO Portion)  for
the  preceding  Distribution Date.  Any pro  rata  allocation described  in this
paragraph will be made among the Subclasses of Class A Certificates (other  than
the  Class A-4 Certificates), the Class A-4 TAC A Component, the Class A-4 TAC B
Component and  the  Class  A-4 TAC  Accrual  Component  on the  basis  of  their
then-outstanding  Class  A Subclass  Principal  Balances or  Component Principal
Balances or, in the  case of the  Class A-4 TAC  Accrual Component, its  initial
Component  Principal  Balance,  if  lower, immediately  prior  to  the preceding
Distribution Date.
 
    The "Component Principal Balance"  of the Class A-4  PO Component as of  any
Determination  Date will be the principal balance  of such Component on the date
of initial issuance of the Class A Certificates less (i) all amounts  previously
distributed to the holders of the Class A-4 Certificates in respect of the Class
A-4  PO Component pursuant to priorities THIRD clause (B) and FOURTH of the Pool
Distribution Amount Allocation and (ii) the principal portion of Excess  Special
Hazard  Losses,  Excess Fraud  Losses  and Excess  Bankruptcy  Losses previously
allocated to the  Class A-4 PO  Component in the  manner described herein  under
"--Subordination  of  Class  B Certificates--Allocation  of  Losses."  After the
Cross-Over Date, the Component Principal Balance  of the Class A-4 PO  Component
will  be subject to further reduction in an  amount equal to the excess, if any,
of (a) the Component Principal Balance of the Class A-4 PO Component as of  such
Determination  Date without regard to this  provision over (b) the Adjusted Pool
Amount (PO Portion) for the preceding Distribution Date.
 
    The "Class A Non-PO 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 (other than the  Class A-4 Certificates) and the Component
Principal Balances of  the Class  A-4 Components (other  than the  Class A-4  PO
Component) as of such date.
 
    The  "Class  B  Subclass  Principal  Balance"  of  a  Subclass  of  Class  B
Certificates as  of  any  Determination Date  will  be  the lesser  of  (a)  the
principal  balance of such Subclass on the date of initial issuance of the Class
B Certificates less (i)  all amounts previously distributed  to holders of  such
Subclass  in reduction of  the principal balance thereof  and (ii) the principal
portion of  Excess  Special  Hazard  Losses,  Excess  Fraud  Losses  and  Excess
Bankruptcy  Losses previously allocated  to the holders of  such subclass in the
manner described under "--Subordination  of Class B Certificates--Allocation  of
Losses"  and (b) the Adjusted Pool Amount  as of the preceding Distribution Date
less the  sum  of (i)  Class  A Non-PO  Principal  Balance, (ii)  the  Component
Principal  Balance of the Class A-4 PO  Component and (iii) the Class B Subclass
Principal Balances  of  the  Subclasses  of  Class  B  Certificates  with  lower
numerical designations, each as of such Determination Date.
 
    The  "Class B Principal Balance" as of any  date will be equal to the sum of
the  Class  B  Subclass  Principal  Balances  of  the  Subclasses  of  Class   B
Certificates as of such date.

    With respect to any Distribution Date, the "Adjusted Pool Amount" will equal
the Cut-Off Date Aggregate Principal Balance of the Mortgage Loans minus the sum
of  (i) all amounts in respect of  principal received in respect of the Mortgage
Loans (including amounts  received as Periodic  Advances, principal  prepayments
and  Liquidation Proceeds in respect of principal) and distributed to holders of
the  Series  1996-6  Certificates  on  such  Distribution  Date  and  all  prior
Distribution  Dates and (ii) the principal portion of all Realized Losses (other
than Debt Service Reductions)  incurred on the Mortgage  Loans from the  Cut-Off
Date through the end of the month preceding such Distribution Date.
 
    With  respect  to  any  Distribution Date,  the  "Adjusted  Pool  Amount (PO
Portion)" will equal the sum as to each Mortgage Loan outstanding at the Cut-Off
Date of the product of  (A) the PO Fraction for  such Mortgage Loan and (B)  the
principal  balance of such Mortgage Loan as of  the Cut-Off Date less the sum of
(i) all amounts  in respect of  principal received in  respect of such  Mortgage
Loan (including amounts received as Periodic Advances, principal prepayments and
Liquidation  Proceeds in respect of principal) and distributed to holders of the
Series 1996-6 Certificates on such Distribution Date and all prior  Distribution
Dates  and (ii) the  principal portion of  any Realized Loss  (other than a Debt
Service Reduction) incurred on such Mortgage Loan from the Cut-Off Date  through
the end of the month preceding the month in which such Distribution Date occurs.
 
    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 sum of (i) the Servicing  Fee Rate ranging from 0.200% to 0.250%
per annum and (ii) the Master Servicing Fee Rate as set forth in the Pooling and
Servicing Agreement  for  such  Mortgage  Loan.  The  initial  weighted  average
Servicing  Fee Rate of the Mortgage Loans is approximately 0.207% per annum. See
"Servicing  of  the  Mortgage  Loans--Servicing  Compensation  and  Payment   of
Expenses" herein.
 
    When  mortgagors  prepay principal  or when  principal is  recovered through
foreclosures or other liquidations of  defaulted Mortgage Loans, a full  month's
interest  for the  month of payment  or recovery  may not be  paid or recovered,
resulting in interest shortfalls.  Interest shortfalls resulting from  principal
prepayments  in full are referred to herein as "Prepayment Interest Shortfalls."
Prepayment Interest Shortfalls occurring with respect to Mortgage Loans serviced
under the PHMC Servicing Agreement will be offset to the extent of the aggregate
Servicing Fees  due thereunder  in  respect of  the related  Distribution  Date.
Interest  shortfalls  resulting  from  the  timing  of  the  receipt  of partial
principal prepayments and of  net Partial Liquidation  Proceeds with respect  to
Mortgage Loans serviced under the PHMC Servicing Agreement will not be offset by
Servicing  Fees payable thereunder, but instead will be borne first by the Class
B Certificates and  then by the  Class A Certificates.  See "Description of  the
Certificates--   Subordination  of  Class  B  Certificates"  herein.  Prepayment
Interest Shortfalls occurring with respect to the Mortgage Loans serviced  under
the  Other Servicing Agreements  and interest shortfalls  resulting from partial
prepayments occurring  with respect  to the  Mortgage Loans  serviced under  the
Other  Servicing Agreements ("Curtailment Interest  Shortfalls"), will be offset
to the extent of the aggregate Servicing Compensation, including Servicing  Fees
(or,  in the  case of the  Countrywide Servicing  Agreement, aggregate Servicing
Fees), due under the related Other Servicing Agreement in respect of the related
Distribution  Date.  As  to  any  Distribution  Date,  (A)  Prepayment  Interest
Shortfalls  occurring with  respect to  Mortgage Loans  serviced under  the PHMC
Servicing Agreement to the extent that they exceed the aggregate Servicing  Fees
payable  thereunder  on  such  Distribution  Date  and  (B)  Prepayment Interest
Shortfalls and  Curtailment Interest  Shortfalls with  respect to  the  Mortgage
Loans  serviced  under  the  Other  Servicing  Agreements  to  the  extent  such
shortfalls exceed the aggregate Servicing Compensation  (or, in the case of  the
Countrywide  Servicing  Agreement,  aggregate  Servicing  Fees)  payable  to the
related Servicer under the  respective Other Servicing  Agreement in respect  of
such  Distribution  Date  are  referred  to  herein  as  "Non-Supported Interest
Shortfalls" and will be allocated to  (i) the Class A Certificates according  to
the  percentage  obtained  by  dividing  the  then-outstanding  Class  A  Non-PO
Principal Balance by the  sum of the then-outstanding  Class A Non-PO  Principal
Balance  and  Class B  Principal  Balance and  (ii)  the Subclasses  of  Class B
Certificates  according   to   the   percentage   obtained   by   dividing   the
then-outstanding Class B Subclass Principal Balance of each such Subclass by the
sum  of  the  then-outstanding Class  A  Non-PO  Principal Balance  and  Class B
Principal Balance. Such allocation of the Non-Supported Interest Shortfall  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 or, in  the
case  of the Class  A-4 Certificates with  respect to the  Class A-4 TAC Accrual
Component prior  to the  Cross-Over Date,  will reduce  the amount  of  interest
accrued on and added to the Component Principal Balance thereof. Such allocation
of the Non-
 
                                      S-32
<PAGE>
Supported  Interest Shortfall will also reduce the  amount of interest due to be
distributed to  the  holders of  the  Class B  Certificates.  Any  Non-Supported
Interest Shortfall allocated to the Class A Certificates will be allocated among
the Subclasses of Class A Certificates pro rata on the basis of their respective
Class  A  Subclass Interest  Accrual Amounts,  without  regard to  any reduction
pursuant to  this  paragraph,  for such  Distribution  Date.  Any  Non-Supported
Interest  Shortfall allocated  to the Class  A-4 Certificates  will be allocated
among the Class A-4 Components (other than the Class A-4 PO Component) pro  rata
on  the basis  of their respective  Component Interest  Accrual Amounts, without
regard to any reduction pursuant to this paragraph, for such Distribution  Date.
See  "Servicing of the Mortgage Loans--Adjustment to Servicing Fee in Connection
with Prepaid Mortgage Loans" in the Prospectus.
 
    The interest  portion of  any  Excess Special  Hazard Losses,  Excess  Fraud
Losses  or Excess Bankruptcy  Losses will be  allocated between the  Class A and
Class B Certificates pro rata based on  the interest accrued on each such  Class
and among the Subclasses of Class A or Class B Certificates, as the case may be,
pro  rata on  the basis  of their respective  Class A  Subclass Interest Accrual
Amounts or Class  B Subclass  Interest Accrual  Amounts, without  regard to  any
reduction  pursuant to  this paragraph, for  such Distribution  Date. Any amount
allocated to the Class  A-4 Certificates will be  allocated among the Class  A-4
Components  (other than  the Class A-4  PO Component)  pro rata on  the basis of
their respective  Component  Interest Accrual  Amounts,  without regard  to  any
reduction pursuant to this paragraph, 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 will result from the priority of distributions first to
the holders  of the  Class A  Certificates of  the Pool  Distribution Amount  as
described above under "Description of the Certificates--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's Class A Subclass Interest Accrual Amount. On each Distribution  Date,
interest  in an  amount equal  to the Component  Interest Accrual  Amount of the
Class A-4 TAC Accrual Component will accrue thereon, but such amount will not be
distributed as interest to the Class A-4 Certificates until the Cross-Over Date.
Prior to such time, an amount equal to the Component Interest Accrual Amount for
the Class A-4 TAC Accrual Component will instead be distributed in reduction  of
the  Class A Subclass Principal Balance  and Component Principal Balances of the
Accretion Directed Certificates, Accretion Directed Components and the Class A-4
TAC Accrual Component as  described under "--Principal (Including  Prepayments)"
below,  and  the  Component  Principal  Balance of  the  Class  A-4  TAC Accrual
Component will be increased by a corresponding amount.
 
    If, on any Distribution Date, the Pool Distribution Amount is less than  the
sum  of the Class  A Subclass Interest  Accrual Amounts, the  amount of interest
currently  distributed  on  the  Class  A  Certificates  will  equal  the   Pool
Distribution  Amount  and will  be  allocated among  the  Subclasses of  Class A
Certificates pro rata in accordance with  each such Subclass's Class A  Subclass
Interest  Accrual Amount. Amounts so allocated will be distributed in respect of
interest to each  Subclass of  Class A Certificates  with the  exception of  the
Class  A-4 Certificates in respect of the  Class A-4 TAC Accrual Component prior
to the  Cross-Over  Date.  Any  difference  between  the  portion  of  the  Pool
Distribution  Amount distributed in respect of current interest to each Subclass
of Class A  Certificates or,  in the  case of  the Class  A-4 Certificates  with
respect  to the Class  A-4 TAC Accrual  Component prior to  the Cross-Over Date,
accrued on and added to the Component Principal Balance thereof, 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. The Class A Subclass  Interest Shortfall Amount of the Class
A-4 Certificates with respect to any  Distribution Date will be allocated  among
the  Class A-4 Components (other than the Class A-4 PO Component) based on their
Component Interest Accrual Amounts (such  shortfall allocated to any  Component,
the   "Component  Interest  Shortfall  Amount").  In   the  event  that  on  any
Distribution Date prior to the Cross-Over  Date the Pool Distribution Amount  is
less than the sum of the Class A Subclass Interest Accrual Amounts, resulting in
Class A Subclass Interest Shortfall Amounts, as described above, an amount equal
to  the Class A-4 TAC Accrual Component Distribution Amount would be distributed
to the Accretion Directed Certificates,
 
                                      S-33
<PAGE>
the Accretion  Directed Components  and  the Class  A-4 TAC  Accrual  Component,
notwithstanding  that the holders of the  Class A Certificates of the Subclasses
then entitled to receive distributions of interest have received less than their
respective Class  A  Subclass Interest  Accrual  Amounts with  respect  to  such
Distribution Date.
 
    On  each Distribution Date on which the Pool Distribution Amount exceeds the
sum of the Class A  Subclass Interest Accrual Amounts,  any excess will then  be
allocated  first to  pay previously unpaid  Class A  Subclass Interest Shortfall
Amounts. Such  amounts  will  be  allocated among  the  Subclasses  of  Class  A
Certificates  pro rata in accordance with the respective unpaid Class A Subclass
Interest Shortfall  Amounts immediately  prior to  such Distribution  Date.  Any
amount allocated to the Class A-4 Certificates will be allocated among the Class
A-4  Components (other than  the Class A-4  PO Component) based  on their unpaid
Component Interest Shortfall Amounts. Prior  to the Cross-Over Date, the  amount
so  allocated to the Class A-4 TAC  Accrual Component will not be distributed as
interest to  the holders  of the  Class A-4  Certificates, but  will instead  be
distributed in reduction of the Class A Subclass Principal Balance and Component
Principal  Balances  of  the  Accretion  Directed  Certificates,  the  Accretion
Directed Components and the Class A-4  TAC Accrual Component as described  under
"--Principal (Including Prepayments)" below, and the Component Principal Balance
of  the Class  A-4 TAC  Accrual Component will  be increased  by a corresponding
amount.
 
    Subject to the  payment of any  Class A-4 PO  Component Deferred Amount,  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 Non-PO Optimal Principal Amount (collectively with the amounts described
in clauses (i) and (ii), the "Class A Non-PO Optimal Amount") and (B) the  Class
A-4  PO  Component  Optimal  Principal  Amount  (collectively  with  the  amount
described in  clause (A),  the  "Senior Optimal  Amount"),  any excess  will  be
allocated to make distributions in respect of interest and then principal on the
Subclasses of Class B Certificates.
 
    On  any Distribution Date on which the Pool Distribution Amount is less than
the Senior Optimal Amount,  the Subclasses of Class  B Certificates will not  be
entitled to any distributions of interest or principal.
 
PRINCIPAL (INCLUDING PREPAYMENTS)
 
    The  principal balance of a Class A  Certificate of any Subclass at any time
is equal  to the  product of  the Class  A Subclass  Principal Balance  of  such
Subclass  and such Certificate's Percentage Interest, and represents the maximum
specified dollar amount (exclusive of (i)  any interest that may accrue on  such
Class  A  Certificate,  other than  interest  added to  the  Component Principal
Balance of the Class A-4 TAC Accrual Component and (ii) in the case of the Class
A-R and Class A-LR Certificates, any additional amounts to which the holders  of
such  Certificates 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 Offered Certificates is set forth
on the  cover  of this  Prospectus  Supplement.  The initial  Class  A  Subclass
Principal   Balance  of  the  Class   A-4  Certificates  will  be  approximately
$70,090,414.
 
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-4 Certificates with  respect to the Class
A-4 PO Component) will  be made on each  Distribution Date pursuant to  priority
THIRD  clause (A)  of the  Pool Distribution  Amount Allocation  in an aggregate
amount equal  to  the  Class  A Principal  Distribution  Amount.  The  "Class  A
Principal  Distribution Amount"  with respect to  any Distribution  Date will be
equal to the sum of (i) the Class A-4 TAC Accrual Component Distribution Amount,
if any, with respect to  such Distribution Date and  (ii) the Class A  Principal
Amount  with  respect to  such  Distribution Date.  The  "Class A-4  TAC Accrual
Component Distribution Amount"  with respect  to any Distribution  Date will  be
equal  to the sum of (i) the portion,  if any, of current interest allocated but
not distributed  to  the  Class A-4  TAC  Accrual  Component of  the  Class  A-4
Certificates  on such Distribution Date in accordance with priority FIRST of the
Pool Distribution Amount Allocation and (ii) the portion, if any, of the  unpaid
Class A Interest Shortfall Amount allocated but not distributed to the Class A-4
TAC Accrual Component of the Class A-4 Certificates on such Distribution Date in
accordance with
 
                                      S-34
<PAGE>
priority  SECOND  of  the  Pool Distribution  Amount  Allocation.  The  "Class A
Principal Amount" with  respect to any  Distribution Date will  be equal to  the
amount   distributed  pursuant  to  priority  THIRD   clause  (A)  of  the  Pool
Distribution Amount Allocation, in an aggregate amount up to the Class A  Non-PO
Optimal Principal Amount.
 
    The  "Class  A  Non-PO  Optimal  Principal  Amount"  with  respect  to  each
Distribution Date  will be  an amount  equal  to the  sum for  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) of the  product of (A) the  Non-PO Fraction for such Mortgage
Loan and (B) the sum of:
 
         (i) the Class A  Percentage of (A) the  scheduled payment of  principal
    due  on  such Mortgage  Loan on  the first  day  of the  month in  which the
    Distribution Date occurs, less  (B) if the Bankruptcy  Loss Amount is  zero,
    the  principal  portion  of Debt  Service  Reductions with  respect  to such
    Mortgage Loan,
 
        (ii) the  Class  A  Prepayment Percentage  of  the  Scheduled  Principal
    Balance of such Mortgage Loan which, during the month preceding the month of
    such Distribution Date was repurchased by the Seller, as described under the
    heading   "Description  of  the   Mortgage  Loans--Mandatory  Repurchase  or
    Substitution of Mortgage Loans" herein,
 
        (iii) The  Class  A  Prepayment  Percentage of  (a)  the  aggregate  net
    Liquidation  Proceeds (other than, with respect  to a Mortgage Loan serviced
    under the PHMC Servicing Agreement, net Partial Liquidation Proceeds) on any
    such Mortgage Loan that became a Liquidated Loan 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, the
    Master Servicer or the Trust  Administrator with respect to such  Liquidated
    Loan  and the portion of such net Liquidation Proceeds allocable to interest
    and (b) with respect  to a Mortgage Loan  serviced under the PHMC  Servicing
    Agreement,  the  aggregate  net  Partial Liquidation  Proceeds  on  any such
    Mortgage Loan received by PHMC, as  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  Determination  Date  occurs,  less  the  amounts  allocable  to
    principal of any unreimbursed Periodic Advances previously made by PHMC,  as
    Servicer,  the Master Servicer or the Trust Administrator and the portion of
    the net Partial Liquidation Proceeds allocable to interest,
 
        (iv) the  Class  A  Prepayment Percentage  of  the  Scheduled  Principal
    Balance  of  each  Mortgage  Loan  which  was  the  subject  of  a principal
    prepayment in full (a)  during the month preceding  the month in which  such
    Distribution Date occurs with respect to any Mortgage Loan serviced under an
    Other  Servicing Agreement or  (b) during the period  from and including the
    Determination Date in  the month  preceding the month  of such  Distribution
    Date up to (but not including) the Determination Date occurring in the month
    of  such Distribution Date with respect  to any Mortgage Loan serviced under
    the PHMC Servicing Agreement,
 
        (v)  the  Class  A  Prepayment  Percentage  of  all  partial   principal
    prepayments (a) received by any Other Servicer with respect to such Mortgage
    Loan  during the month  preceding the month in  which such Distribution Date
    occurs and (b) received  by PHMC with  respect to such  Mortgage Loan on  or
    after  the Determination Date occurring in  the month preceding the month in
    which such  Distribution Date  occurs and  prior to  the Determination  Date
    occurring in the month in which such Distribution Date occurs, and
 
        (vi)  the  Class  A  Percentage of  the  difference  between  the unpaid
    principal balance  of any  such 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 amount allocable  to the principal  portion of any
    unreimbursed advances in respect of such defective Mortgage Loan.
 
    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  (other than  the Class  A-4 Certificates)  or to  any  Component
(other  than  the  Class  A-4  PO Component),  each  such  Subclass  of  Class A
Certificates or Component  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 or  Component Principal Balance  of such Subclass  or
Component was reduced as a result of such Realized Loss.

    The  "Non-PO Fraction" with respect to any  Mortgage Loan will equal the Net
Mortgage Interest Rate for such Mortgage Loan divided by 7.25%, but shall not be
greater than 1.0.
 
    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  and
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  and, with respect  to Mortgage Loans  serviced under the  PHMC
Servicing   Agreement,  any  partial  principal   prepayments  and  net  Partial
Liquidation Proceeds applied as of such  Due Date and any principal  prepayments
in full received prior to the Determination Date in the month of such Due Date.
 
    "Partial Liquidation Proceeds" are Liquidation Proceeds received by PHMC, as
Servicer,  on a Mortgage Loan prior to  such Mortgage Loan becoming a Liquidated
Loan and "net  Partial Liquidation  Proceeds" are  Partial Liquidation  Proceeds
less  expenses incurred with respect to such liquidation. 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 accrued 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 any Servicer,  the Master Servicer  or the Trust  Administrator
for  any  previously unreimbursed  Periodic 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) a  Liquidated Loan  Loss suffered  by a
Mortgaged Property on account of direct physical loss exclusive of (i) any  loss
covered  by a standard hazard insurance policy  or, if the Mortgaged Property is
located in an area identified in  the Federal Register by the Federal  Emergency
Management  Agency as having special flood hazards, a flood insurance policy, of
the types  described  in  the  Prospectus  under  "The  Trust  Estates--Mortgage
Loans--Insurance  Policies" and  (ii) any loss  caused by or  resulting from (a)
normal  wear  and  tear,   (b)  dishonest  acts  of   the  Trustee,  the   Trust
Administrator,  the Master Servicer or the  applicable Servicer or (c) errors in
design, faulty  workmanship or  faulty  materials, unless  the collapse  of  the
property  or a part thereof ensues or (B) a Liquidated Loan Loss arising from or
relating to the presence or suspected presence of hazardous wastes or substances
on a Mortgaged Property. 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 Debt Service Reduction or a Deficient  Valuation.
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 on or 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 Pool Balance (Non-PO  Portion). The "Pool Balance  (Non-PO
Portion)"  is the sum for  each outstanding Mortgage Loan  of the product of (i)
the Non-PO Fraction  for such  Mortgage Loan  and (ii)  the Scheduled  Principal
Balance  of  such  Mortgage Loan  as  of  such Distribution  Date.  The  Class A
Percentage for the  first Distribution  Date will be  approximately 93.70%.  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 (other than  the
Class  A-4 Certificates  with respect  to the Class  A-4 PO  Component) and will
increase as  a result  of  the allocation  of Realized  Losses  to the  Class  B
Certificates.  The Class A Percentage for each Distribution Date occurring after
the Cross-Over Date will be 100%.

    The "Class A Prepayment  Percentage" for any Distribution  Date will be  the
percentage indicated below:

May 2004 through April 2005..............  the Class A Percentage, plus 20% of
                                           the Class B Percentage; and
May 2005 and thereafter..................  the Class A Percentage;
</TABLE>
 
    PROVIDED,  HOWEVER, that if  on any of the  foregoing Distribution Dates the
Class A  Percentage  exceeds  the  initial  Class  A  Percentage,  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 on any Distribution  Date if (i) as of  such Distribution Date as  to
which  any such reduction applies, the  average outstanding principal balance on
such Distribution Date  and for  the preceding  five Distribution  Dates on  the
Mortgage  Loans that 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) is greater
than or equal to 50% of the then-outstanding Class B Principal Balance, or  (ii)
cumulative  Realized Losses with respect to the Mortgage Loans exceed (a) 30% of
the principal balance of the  Class B Certificates as  of the Cut-Off Date  (the
"Original  Subordinated  Principal Balance")  if  such Distribution  Date occurs
between and  including  May  2001  and  April 2002,  (b)  35%  of  the  Original
Subordinated  Principal  Balance if  such Distribution  Date occurs  between and
including May  2002  and  April  2003, (c)  40%  of  the  Original  Subordinated
Principal  Balance if  such Distribution Date  occurs between  and including May
2003 and April 2004, (d) 45%  of the Original Subordinated Principal Balance  if
such Distribution Date occurs between and including May 2004 and April 2005, and
(e) 50% of the Original Subordinated Principal Balance if such Distribution Date
occurs  during or  after May 2005.  This disproportionate  allocation of certain
unscheduled  payments  in  respect  of   principal  will  have  the  effect   of
accelerating  the amortization of the Class A Certificates (other than the Class
A-4 Certificates  with respect  to the  Class A-4  PO Component)  while, in  the
absence  of Realized Losses, increasing the interest in the principal balance of
the Mortgage  Loans  evidenced  by  the Class  B  Certificates.  Increasing  the
respective  interest of the Class B Certificates relative to that of the Class A
Certificates (other than the  Class A-4 Certificates with  respect to the  Class
A-4  PO Component) is intended to preserve the availability of the subordination
provided  by  the  Class  B  Certificates.  See  "--Subordination  of  Class   B
Certificates"  below. The "Class B Percentage" for any Distribution Date will be
calculated as the difference  between 100% and the  Class A Percentage for  such
date.  The "Class  B 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 (other than the  Class A-4 Certificates with  respect to the  Class
A-4 PO Component) of full and partial principal prepayments and other amounts in
the  percentage  required  above would  reduce  the outstanding  Class  A Non-PO
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   Non-PO  Principal   Balance  to   zero.  See   "Description  of   the
Certificates--Distributions  to Percentage Certificateholders--Shifting Interest
Certificates" in the Prospectus.
 
  CALCULATION OF AMOUNT TO BE DISTRIBUTED TO THE CLASS A-4 PO COMPONENT
 
    Distributions in reduction of the  Component Principal Balance of the  Class
A-4  PO Component will be made on  each Distribution Date in an aggregate amount
equal to the Class  A-4 PO Component Principal  Distribution Amount. The  "Class
A-4 PO Component Principal Distribution Amount" with respect to any Distribution
Date will be equal to the sum of (i) the amount distributed pursuant to priority
THIRD clause (B) of the Pool Distribution Amount
 
                                      S-37
<PAGE>
Allocation,  in an  aggregate amount  up to the  Class A-4  PO Component Optimal
Principal Amount and (ii) the amount distributed pursuant to priority FOURTH  of
the  Pool Distribution Amount Allocation, in an aggregate amount up to the Class
A-4 PO Component Deferred Amount.
 
    The "Class A-4 PO Component Optimal  Principal Amount" with respect to  each
Distribution  Date  will be  an amount  equal  to the  sum for  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) of the product of  (A) the PO Fraction for such Mortgage  Loan
and (B) the sum of:
 
         (i) the scheduled payment of principal due on such Mortgage Loan on the
    first  day of the month in which  the Distribution Date occurs, less, if the
    Bankruptcy Loss  Amount  is zero,  the  principal portion  of  Debt  Service
    Reductions with respect to such Mortgage Loan,
 
        (ii) the Scheduled Principal Balance of such Mortgage Loan which, during
    the  month preceding the month of  such Distribution Date was repurchased by
    the Seller,  as described  under the  heading "Description  of the  Mortgage
    Loans--Mandatory Repurchase or Substitution of Mortgage Loans" herein,
 
        (iii) the sum of (a) the aggregate net Liquidation Proceeds (other than,
    with respect to a Mortgage Loan serviced under the PHMC Servicing Agreement,
    net  Partial Liquidation Proceeds)  on any such Mortgage  Loan that became a
    Liquidated Loan 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, the Master  Servicer or  the Trust Administrator  with respect  to
    such  Liquidated  Loan  and the  portion  of such  net  Liquidation Proceeds
    allocable to interest and (b) with respect to a Mortgage Loan serviced under
    the PHMC Servicing Agreement, the aggregate net Partial Liquidation Proceeds
    on any such Mortgage  Loan received by  PHMC, as 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, less the amounts allocable
    to  principal of any unreimbursed Periodic Advances previously made by PHMC,
    as Servicer, the Master Servicer or the Trust Administrator and the  portion
    of the net Partial Liquidation Proceeds allocable to interest,
 
        (iv) the Scheduled Principal Balance of such Mortgage Loan which was the
    subject of a principal prepayment in full (a) during the month preceding the
    month  in which such  Distribution Date occurs with  respect to any Mortgage
    Loan serviced under an  Other Servicing Agreement or  (b) during the  period
    from  and including the Determination Date  in the month preceding the month
    of such Distribution Date up to  (but not including) the Determination  Date
    occurring in the month of such Distribution Date, with respect to a Mortgage
    Loan serviced under the PHMC Servicing Agreement,
 
        (v)  all partial principal prepayments (a) received by an Other Servicer
    with respect to such Mortgage Loan  during the month preceding the month  in
    which  such Distribution  Date occurs or  (b) 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 with respect to a Mortgage Loan serviced
    under the PHMC Servicing Agreement, and
 
        (vi) the difference  between the  unpaid principal balance  of any  such
    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 amount allocable
    to  the principal  portion of any  unreimbursed advances in  respect of such
    defective Mortgage Loan. See "The Trust Estates-- Mortgage Loans--Assignment
    of Mortgage Loans to the Trustee" in the Prospectus.
 
    The "Class A-4 PO Component Deferred Amount" for any Distribution Date prior
to the Cross-Over Date will equal the difference between (A) the sum of (i)  the
amount  by which  the Class  A-4 PO Component  Optimal Principal  Amount for all
prior Distribution Dates  exceeds the amounts  distributed on the  Class A-4  PO
Component  on such prior  Distribution Dates pursuant  to priority THIRD, clause
(B) of the  Pool Distribution  Amount Allocation, but  only to  the extent  such
shortfall  is not attributable to Realized Losses  allocated to the Class A-4 PO
Component as described in  "--Subordination of Class B  Certificates--Allocation
of Losses" below and (ii) the sum of the product for each Discount Mortgage Loan
which  became a Liquidated Loan in any  month preceding the month of the current
Distribution Date of (a) the PO Fraction for such Discount Mortgage Loan and (b)
an amount equal to the
 
                                      S-38
<PAGE>
principal portion of Realized Losses (other  than Bankruptcy Losses due to  Debt
Service  Reductions) incurred with respect to  such Discount Mortgage Loan other
than Excess Special  Hazard Losses,  Excess Fraud Losses  and Excess  Bankruptcy
Losses and (B) amounts distributed on the Class A-4 PO Component Certificates on
prior  Distribution Dates pursuant  to priority FOURTH  of the Pool Distribution
Amount Allocation. On or after the  Cross-Over Date, the Class A-4 PO  Component
Deferred  Amount  will be  zero. No  interest will  accrue on  any Class  A-4 PO
Component Deferred Amount.
 
    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-4 PO Component, such Component if outstanding will be entitled to its share of
such recovery in an  amount up to  the amount by  which the Component  Principal
Balance  of the Class A-4 PO Component was  reduced as a result of such Realized
Loss.
 
    The "PO Fraction" with respect to any Discount Mortgage Loan will equal  the
difference  between 1.0 and the  Non-PO Fraction for such  Mortgage Loan. The PO
Fraction with respect to each Mortgage Loan that is not a Discount Mortgage Loan
will be zero.
 
    The "Pool Balance (PO Portion)" is  the sum for each Discount Mortgage  Loan
of  the product of the Scheduled Principal Balance of such Mortgage Loan and the
PO Fraction for such Mortgage Loan.
 
ALLOCATION OF AMOUNT TO BE DISTRIBUTED
 
    On each Distribution Date occurring prior to the Cross-Over Date, an  amount
equal  to the Class A-4  TAC Accrual Component Distribution  Amount, if any, for
such Distribution Date will be allocated as follows:
 
    FIRST, concurrently, to  the Class  A-4 TAC A  Component and  the Class  A-3
Certificates,  pro rata, until the Component  Principal Balance of the Class A-4
TAC A Component  and the Class  A Subclass  Principal Balance of  the Class  A-3
Certificates have been reduced to zero;
 
    SECOND,  to  the Class  A-4 TAC  B Component  until the  Component Principal
Balance thereof has been reduced to zero; and
 
    THIRD, to the Class A-4 TAC Accrual Component until the Component  Principal
Balance thereof has been reduced to zero.
 
    On  each Distribution Date occurring prior to the Cross-Over Date, the Class
A Principal Distribution Amount (other than the Class A-4 TAC Accrual  Component
Distribution Amount) will be allocated among and distributed in reduction of the
Class  A  Subclass  Principal  Balances  of  the  other  Subclasses  of  Class A
Certificates as follows:
 
    FIRST, to the Class A-6 Certificates up to the Class A-6 Priority Amount;
 
    SECOND, to the Class A-1 Certificates  up to their PAC Principal Amount  for
such Distribution Date;
 
    THIRD,  to the Class A-2  Certificates up to their  PAC Principal Amount for
such Distribution Date;
 
    FOURTH, concurrently, to  the Class A-4  TAC A Component  and the Class  A-3
Certificates,  pro rata, up  to their respective TAC  Principal Amounts for such
Distribution Date;
 
    FIFTH, to the Class A-4 TAC B  Component up to its TAC Principal Amount  for
such Distribution Date;
 
    SIXTH, to the Class A-4 TAC Accrual Component up to its TAC Principal Amount
for such Distribution Date;
 
    SEVENTH,   concurrently,  to  the  Class  A-5,  Class  A-R  and  Class  A-LR
Certificates, pro rata,  until the Class  A Subclass Principal  Balance of  each
such Subclass has been reduced to zero;
 
    EIGHTH,  concurrently, to the  Class A-4 TAC  A Component and  the Class A-3
Certificates, pro rata, without regard to their TAC Principal Amounts, until the
Component Principal Balance of  the Class A-4  TAC A Component  and the Class  A
Subclass  Principal Balance of  the Class A-3 Certificates  have been reduced to
zero;
 
    NINTH, to the Class A-4 TAC B Component, without regard to its TAC Principal
Amount, until the Component Principal Balance thereof has been reduced to zero;
 
                                      S-39
<PAGE>
    TENTH, to the  Class A-4 TAC  Accrual Component, without  regard to its  TAC
Principal Amount, until the Component Principal Balance thereof has been reduced
to zero;
 
    ELEVENTH,  to  the  Class  A-1 Certificates,  without  regard  to  their PAC
Principal Amount, until the Class A Subclass Principal Balance thereof has  been
reduced to zero;
 
    TWELFTH,  to  the  Class  A-2  Certificates,  without  regard  to  their PAC
Principal Amount, until the Class A Subclass Principal Balance thereof has  been
reduced to zero; and
 
    THIRTEENTH,  to  the  Class  A-6 Certificates  until  the  Class  A Subclass
Principal Balance thereof has been reduced to zero.
 
    The "Class A-6 Priority Amount" for  any Distribution Date means the  lesser
of  (i) the Class A Subclass Principal Balance of the Class A-6 Certificates and
(ii) the sum  of (A) the  product of (1)  the Class A-6  Percentage and (2)  the
Scheduled  Principal Amount and (B) the product of (1) the Class A-6 Percentage,
(2) the Class A-6 Prepayment Shift Percentage, and (3) the Unscheduled Principal
Amount.
 
    The "Class A-6 Percentage" means the  Class A Subclass Principal Balance  of
the Class A-6 Certificates divided by the Pool Balance (Non-PO Portion).
 
    The "Scheduled Principal Amount" means the sum for 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) of the product of (A) the Non-PO Fraction for such Mortgage Loan and (B)
the sum of the amounts described in clauses B(i) and B(vi) of the definition  of
"Class  A Non-PO Optimal Principal Amount" on page S-35, but without that amount
being multiplied by the Class A Percentage.
 
    The "Unscheduled  Principal  Amount"  means the  sum  for  each  outstanding
Mortgage  Loan (including each defaulted Mortgage  Loan, other than a Liquidated
Loan, with respect to which the  related Mortgage Property has been acquired  by
the  Trust Estate) of the  product of (A) the  Non-PO Fraction for such Mortgage
Loan and (B) the sum  of the amounts described  in clauses B(ii), B(iii),  B(iv)
and  B(v) of the definition of "Class A Non-PO Optimal Principal Amount" on page
S-35, but  without  that amount  being  multiplied  by the  Class  A  Prepayment
Percentage.
 
    The  "Class A-6 Prepayment Shift Percentage"  for any Distribution Date will
be the percentage indicated below:

    As used above, the "PAC Principal Amount" for any Distribution Date and  for
any Subclass of PAC Certificates means the amount, if any, that would reduce the
Class  A Subclass Principal  Balance of such  Subclass to the  percentage of its
initial Class A Subclass  Principal Balance shown in  the following tables  with
respect to such Distribution Date.
 
    As  used above, the "TAC Principal Amount" for any Distribution Date and for
the TAC Certificates and each TAC Component means the amount, if any, that would
reduce the Class A Subclass Principal Balance of such Subclass or the  Component
Principal  Balance of such  Component to the  percentage of its  initial Class A
Subclass Principal Balance or initial  Component Principal Balance, as the  case
may be, shown in the following tables with respect to such Distribution Date.
 
    Notwithstanding  the foregoing,  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 (other than the Class
A-4 Certificates)  and the  TAC Components  pro rata  in accordance  with  their
respective  outstanding  Class  A  Subclass  Principal  Balances  and  Component
Principal Balances without regard to the priorities set forth above.

  PRINCIPAL   PAYMENT  CHARACTERISTICS   OF  THE   PAC  CERTIFICATES,   THE  TAC
   CERTIFICATES, THE TAC COMPONENTS AND THE COMPANION CERTIFICATES
 
    The percentages  of the  initial  Class A  Subclass Principal  Balances  and
Component  Principal Balances of the PAC  Certificates, the TAC Certificates and
the TAC Components set forth in  the preceding tables were calculated using  the
assumptions described in the second paragraph on page S-72 herein. Based on such
assumptions,  the Class  A Subclass  Principal Balance  of each  Subclass of PAC
Certificates would be reduced to the percentage of its initial Class A  Subclass
Principal  Balance indicated in the preceding  tables for each Distribution Date
if prepayments  on  the  Mortgage  Loans occur  at  any  CONSTANT  rate  between
approximately   100%  SPA  (as  defined   herein  under  "Prepayment  and  Yield
Considerations") and  approximately 600%  SPA. Based  on such  assumptions,  the
Class  A Subclass Principal  Balance and Component Principal  Balance of the TAC
Certificates and each TAC  Component would be reduced  to the percentage of  its
Class   A  Subclass  Principal  Balance   or  Component  Principal  Balance,  as
applicable, indicated  in the  preceding tables  for each  Distribution Date  if
prepayments on the Mortgage Loans occur at a CONSTANT rate of approximately 250%
SPA.  However, IT IS HIGHLY UNLIKELY  THAT PRINCIPAL PREPAYMENTS ON THE MORTGAGE
LOANS WILL OCCUR AT ANY CONSTANT RATE OR THAT THE MORTGAGE LOANS WILL PREPAY  AT
THE  SAME RATE. In  addition, even if  principal prepayments were  to occur at a
constant rate,  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. Therefore, there can  be
no  assurance that the Class A Subclass Principal Balance of any Subclass of PAC
Certificates or TAC Certificates or the  Component Principal Balance of any  TAC
Component,  after  the  application  of  the distributions  to  be  made  on any
Distribution Date, will  be equal to  the applicable percentage  of the  initial
Class   A  Subclass  Principal  Balance   or  Component  Principal  Balance,  as
applicable, for such Distribution Date specified in the preceding tables.
 
    As  discussed  under  "Prepayment  and  Yield  Considerations"  herein,  the
weighted  average  life of  a  Subclass of  Offered  Certificates refers  to the
average amount  of time  that will  elapse from  the date  of issuance  of  such
Subclass  until  each  dollar in  reduction  of  the principal  balance  of such
Subclass is distributed to investors. The weighted average life of each Subclass
of Class A Certificates  will be affected,  to varying degrees,  by the rate  of
principal  payments (including prepayments) on the Mortgage Loans, the timing of
changes in such rate of payment  and the priority of distributions in  reduction
of  principal of the  Class A Certificates  and the timing  of reductions of the
principal balances and Component Principal Balances of the PAC Certificates, the
TAC Certificates and the  TAC Components to  their respective planned  principal
balances,  targeted principal balance and targeted Component Principal Balances.
The interaction of these factors may have different effects on the Subclasses of
Class A Certificates, including the  PAC Certificates, the TAC Certificates  and
the  Class A-4 Certificates by virtue of  the TAC Components, and the effects on
any Subclass  may vary  at different  times during  the life  of such  Subclass.
Further,  to the extent that the purchase prices paid by investors for the Class
A Certificates, including  the PAC  Certificates, the TAC  Certificates and  the
Class  A-4  Certificates, represent  discounts or  premiums to  their respective
initial principal balances, variability  in the weighted  average lives of  such
Certificates  could result in variability in the related yields to maturity. See
"Prepayment and Yield Considerations" herein.
 
    The weighted average lives of the  Subclasses of PAC Certificates will  vary
under  different prepayment scenarios. To  the extent that principal prepayments
occur at a CONSTANT rate that is slower than approximately 100% SPA with respect
to the PAC Certificates, the Class A Principal Amount on each Distribution  Date
may be insufficient to make distributions in reduction of the principal balances
of  one or both of the Subclasses of  the PAC Certificates in amounts that would
reduce their principal balances to  their respective planned principal  balances
for  such Distribution Date. The weighted average lives of the Subclasses of PAC
Certificates may therefore be extended,  as illustrated by the tables  beginning
on page S-73.
 
    To  the extent that such principal prepayments occur at a CONSTANT rate that
is higher than approximately 600% SPA with respect to the PAC Certificates,  the
weighted  average lives of the Subclasses  of PAC Certificates may be shortened,
as illustrated by the tables beginning on page S-73.
 
                                      S-45

    To the extent that principal prepayments are made at a CONSTANT rate that is
slower than  approximately  250% SPA,  the  Class  A Principal  Amount  on  each
Distribution  Date may be insufficient to make distributions in reduction of the
principal balance and Component  Principal Balances of  the TAC Certificates  or
some  or all of the TAC Components  in amounts that would reduce their principal
balance and Component Principal Balances to their respective targeted  principal
balance  and targeted Component  Principal Balances for  such Distribution Date.
The  weighted  average  lives  of  the  TAC  Certificates  and  the  Class   A-4
Certificates  by  virtue of  the TAC  Components may  therefore be  extended, as
illustrated, in the  case of the  TAC Certificates, by  the tables beginning  on
page  S-73. To the  extent that such  principal prepayments occur  at a CONSTANT
rate that is higher than approximately  250% SPA, the weighted average lives  of
the  TAC  Certificates and  the  Class A-4  Certificates  by virtue  of  the TAC
Components  may  be  shortened,  as  illustrated,   in  the  case  of  the   TAC
Certificates, by the tables beginning on page S-73.
 
    The  weighted  average life  of the  Companion  Certificates will  be highly
sensitive to  the rate  of  principal payments  (including prepayments)  on  the
Mortgage Loans. See "Prepayment and Yield Considerations" herein.
 
    The  extent to which the planned principal balances will be achieved and the
sensitivity of the  PAC Certificates  to principal prepayments  on the  Mortgage
Loans  will depend, in part, upon the  period of time during which the Companion
Certificates, the TAC Certificates and the TAC Components remain outstanding. On
each Distribution Date,  the excess  of the Class  A Principal  Amount over  the
Class  A-6  Priority Amount  and the  PAC  Principal Amounts  ("Excess Principal
Payments") for  such Distribution  Date  will be  distributed to  the  Companion
Certificates,   the  TAC  Certificates  and  the  TAC  Components  before  being
distributed to  the PAC  Certificates  in accordance  with the  proportions  and
priorities  set forth  above under "--Allocation  of Amount  to be Distributed."
This is intended to decrease the  likelihood that the principal balances of  the
PAC Certificates and will be reduced below their planned principal balances on a
given  Distribution  Date.  As  such,  and  in  accordance  with  the priorities
described above, the Companion  Certificates, the TAC  Certificates and the  TAC
Components  support the PAC Certificates. However, under certain relatively fast
prepayment scenarios, one or both Subclasses of PAC Certificates may continue to
be outstanding when the Subclasses of  Class A Certificates and Components  that
support   such  Subclass  or  Subclasses  of  PAC  Certificates  are  no  longer
outstanding. Under such  circumstances, all  Excess Principal  Payments will  be
applied  to the  remaining PAC  Certificates in  accordance with  the priorities
described  herein.  Thus,   when  the  principal   balances  of  the   Companion
Certificates,  the TAC Certificates and the  TAC Components have been reduced to
zero, any Subclasses of  PAC Certificates then  outstanding will, in  accordance
with  the proportions and  priorities set forth above,  become more sensitive to
the rate of prepayment on the Mortgage Loans as such Subclass or Subclasses will
receive all Excess Principal  Payments until the principal  balances of the  PAC
Certificates  have been  reduced to  zero. Conversely,  under certain relatively
slow prepayment scenarios, the Class A Principal Amount may not be sufficient to
pay the PAC Principal Amounts for the related Subclasses of PAC Certificates  on
a  given Distribution Date. In such cases, the Class A Principal Amount for each
subsequent Distribution Date will be  applied in accordance with the  priorities
described  herein such that the Companion Certificates, the TAC Certificates and
the TAC Components  will not  receive any  distributions in  reduction of  their
principal  balances  or  Component  Principal  Balances  until  the  outstanding
principal balance of  each such  Subclass of  PAC Certificates  has reached  its
planned  principal balance for such Distribution Date. As a result, the weighted
average life  of  any Subclass  of  PAC Certificates  may  be extended  if  such
Subclass does not receive its PAC Principal Amount on a Distribution Date.
 
    The  extent to which the targeted  principal balances and targeted Component
Principal Balances will be achieved and the sensitivity of the TAC  Certificates
and  the  TAC Components  to principal  prepayments on  the Mortgage  Loans will
depend, in part, upon the period of time during which the Companion Certificates
remain outstanding. On  each Distribution Date,  Excess Principal Payments  over
the  TAC Principal Amounts for such Distribution Date will be distributed to the
Companion Certificates, before being distributed to the TAC Certificates and the
TAC Components,  in  accordance  with  the  priorities  set  forth  above  under
"--Allocation  of Amount  to be Distributed."  This is intended  to decrease the
likelihood that the principal  balance and Component  Principal Balances of  the
TAC  Certificates and  the TAC Components  will be reduced  below their targeted
principal balance and targeted Component Principal Balance on such  Distribution
Date.  As  such, and  in  accordance with  the  priorities described  above, the
Companion Certificates  support the  TAC Certificates  and the  TAC  Components.
However,   under  certain   relatively  fast   prepayment  scenarios,   the  TAC
Certificates or one or more of the TAC Components may continue to be outstanding
when   the   Companion   Certificates   are   no   longer   outstanding.   Under
 
                                      S-46
<PAGE>
such  circumstances, all  Excess Principal Payments  will be applied  to the TAC
Certificates and the  TAC Components. Thus,  when the principal  balance of  the
Companion  Certificates  has  been reduced  to  zero, the  TAC  Certificates, if
outstanding, and the TAC  Components then outstanding  will, in accordance  with
the  proportions and priorities  set forth herein, become  more sensitive to the
rate of prepayment on  the Mortgage Loans as  such Subclass and Components  will
receive  all Excess Principal Payments until the principal balance and Component
Principal Balances of  the TAC  Certificates and  the TAC  Components have  been
reduced to zero. Conversely, under certain relatively slow prepayment scenarios,
Excess  Principal  Payments,  if any,  may  not  be sufficient  to  pay  the TAC
Principal Amounts for  the TAC Certificates  and the TAC  Components on a  given
Distribution  Date. In such cases, Excess Principal Payments for such subsequent
Distribution Date  will  be  applied  in accordance  with  the  proportions  and
priorities  described  herein  such  that the  Companion  Certificates  will not
receive any  distributions in  reduction of  their principal  balance until  the
outstanding  principal  balance  and  Component Principal  Balances  of  the TAC
Certificates and each of the TAC  Components has reached its targeted  principal
balance  or  targeted  Component  Principal  Balance,  as  applicable,  for such
Distribution  Date.  As  a  result,  the  weighted  average  life  of  the   TAC
Certificates,  or of the Class A-4 Certificates by virtue of the TAC Components,
may be extended if such Subclass or any such Component does not receive its  TAC
Principal Amount on such Distribution Date.
 
    Because  any Excess  Principal Payments  for any  Distribution Date  will be
distributed to  Certificateholders on  such Distribution  Date, the  ability  to
distribute   the  PAC  Principal  Amounts  and  TAC  Principal  Amounts  on  any
Distribution Date  will  not  be enhanced  by  the  averaging of  high  and  low
principal  prepayment  rates on  the  Mortgage Loans  over  several Distribution
Dates, as might be the case if any such Excess Principal Payments were held  for
future  applications and  not distributed monthly.  There is  no assurance that,
with respect to the Class A  Principal Amount (i) distributions in reduction  of
the  Class A Subclass Principal  Balance of any Subclass  of PAC Certificates or
the TAC Certificates  or the Component  Principal Balance of  any TAC  Component
(other  than the Class  A-1 and Class A-3  Certificates and the  Class A-4 TAC A
Component) will not commence significantly  earlier than the first  Distribution
Date  shown in the preceding tables relating to such Subclass or Component, (ii)
distributions in reduction  of the  Class A  Subclass Principal  Balance of  any
Subclass  of PAC  Certificates or  the TAC  Certificates or  Component Principal
Balances of any  TAC Component will  not commence significantly  later than  the
first  Distribution Date shown in the preceding tables relating to such Subclass
or Component or (iii) the Class A Subclass Principal Balance of any Subclass  of
PAC  Certificates or the TAC Certificates or Component Principal Balances of any
TAC Component will not be reduced to zero significantly earlier or significantly
later than the last Distribution Date shown in the preceding tables.
 
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  either such Subclass is
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 1996-6 Certificates,  after distributions in respect of any
accrued but  unpaid  interest  on  the  Series  1996-6  Certificates  and  after
distributions  in  reduction of  principal  balance have  reduced  the principal
balances of the Series 1996-6 Certificates  to zero. It is not anticipated  that
there will be any assets remaining in the Trust Estate on the final Distribution
Date  following  the distributions  of interest  and  in reduction  of principal
balance made on the Series 1996-6 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.  "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  undistributed portion of the  Pool
Distribution Amounts.

PERIODIC ADVANCES
 
    If, on any Determination Date, payments of principal and interest due on any
Mortgage  Loan  in  the Trust  Estate  on the  related  Due Date  have  not been
received, the Servicer of  the Mortgage Loan or,  upon such Servicer's  default,
the Master Servicer will, in certain circumstances, be required to advance on or
before  the related Distribution Date  for the benefit of  holders of the Series
1996-6 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 advancing party  believes that such
amounts will be recoverable by it from liquidation proceeds or other  recoveries
in  respect of the  related Mortgage Loan  (each, a "Periodic  Advance"). In the
event that both  the related Servicer  and the  Master Servicer fail  to make  a
Periodic  Advance, the  Trust Administrator  is required  to make  such Periodic
Advance from its own funds.
 
    The Servicing Agreements  and the  Pooling and  Servicing Agreement  provide
that  any  advance of  the  kind described  in  the preceding  paragraph  may be
reimbursed  to  the  related  Servicer,   the  Master  Servicer  or  the   Trust
Administrator,  as applicable, at any time from funds available in the Custodial
Account or the Master  Servicer Custodial Account,  as the case  may be, 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,  the  Master  Servicer  or  the Trust
Administrator, as applicable, has  determined in good  faith that the  advancing
party  will be unable to recover such advance from funds of the type referred to
in clause (i) above.
 
RESTRICTIONS ON TRANSFER OF THE CLASS A-R AND CLASS A-LR 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 and (ii) certain Pass-Through Entities (as defined in
the Prospectus) that  have Disqualified Organizations  as beneficial owners.  No
tax  will be imposed on  a Pass-Through Entity with respect  to the Class A-R or
Class A-LR Certificate to the extent it has received an affidavit from the owner
thereof that such owner is  not a Disqualified Organization  or a nominee for  a
Disqualified Organization. The Pooling and Servicing Agreement will provide that
no  legal or beneficial interest in 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 Trust Administrator an affidavit (or, to the
extent acceptable to  the Trust  Administrator, a  representation letter  signed
under penalty of perjury) to the effect that, among other items, such transferee
is  not a Disqualified  Organization (as defined  in the Prospectus)  and is not
purchasing  the  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 Trust  Administrator
that  it has  no actual  knowledge that such  affidavit is  false. Further, such
affidavit (or letter) 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 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 (or  letter). The  transferor must  certify in  writing to  the  Trust
Administrator  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 such 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  Trust  Administrator with  an  effective  Internal Revenue
Service Form 4224 or (ii) the transferee delivers to both the transferor and the
Trust Administrator 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.
 
                                      S-48
<PAGE>
    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 Trust Administrator 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  Residual
Certificates" in the Prospectus.
 
    Neither  the Class  A-R Certificate  nor the  Class A-LR  Certificate may be
purchased by or transferred to a Plan. See "ERISA Considerations" herein and  in
the Prospectus.
 
REPORTS
 
    In  addition to the applicable information  specified in the Prospectus, the
Master Servicer will include  in the statement delivered  to holders of  Offered
Certificates  with respect to each  Distribution Date the following information:
(i) the  amount  of such  distribution  allocable  to interest,  the  amount  of
interest  currently distributable to each Subclass  of Class A Certificates, any
Class A  Subclass  Interest  Shortfall  Amount  arising  with  respect  to  each
Subclass,  any remaining unpaid Class A  Subclass Interest Shortfall Amount with
respect to  each Subclass  after  giving effect  to  such distribution  and  any
Non-Supported  Interest  Shortfall or  the interest  portion of  Realized Losses
allocable to such  Subclass with  respect to  such Distribution  Date, (ii)  the
amount  of such  distribution allocable to  principal, (iii) the  Class A Non-PO
Principal Balance,  the  Component  Principal  Balances  of  the  Class  A-4  PO
Component,  the Class A-4 TAC A Component, the Class A-4 TAC B Component and the
Class A-4 TAC Accrual Component, 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 the principal portion of Realized Losses to such
Subclass with respect to such Distribution Date, (iv) the Adjusted Pool  Amount,
the  Adjusted Pool Amount (PO Portion)  and the Pool Scheduled Principal Balance
of the  Mortgage Loans  and the  aggregate Scheduled  Principal Balance  of  the
Discount  Mortgage Loans for such Distribution  Date, (v) the Class A Percentage
for  the  following  Distribution  Date   (without  giving  effect  to   partial
prepayments  and  net Partial  Liquidation Proceeds  received on  Mortgage Loans
serviced under the PHMC Servicing Agreement after the Determination Date in  the
current  month that are applied as of the  Due Date occurring in such month) 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
Certificates will also include the Class A-4 IO A Component Notional Amount, the
Class  A-4 IO B Component Notional Amount  and the weighted average Net Mortgage
Interest Rates of  the Premium  Mortgage Loans applicable  to such  Distribution
Date   minus   7.25%.  See   "Servicing  of   the  Mortgage   Loans--Reports  to
Certificateholders" in the Prospectus.
 
    Copies of the foregoing  reports are available upon  written request to  the
Trust  Administrator at its  corporate trust office.  See "Pooling and Servicing
Agreement--Trust Administrator" herein.
 
SUBORDINATION OF CLASS B CERTIFICATES
 
    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 Certificates 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 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  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 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 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 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  B  Certificates. The
application of this subordination to cover Realized
 
                                      S-49
<PAGE>
Losses experienced in periods prior to the periods in which a Subclass of  Class
A  Certificates is entitled  to distributions in  reduction of principal balance
will decrease the protection provided by the subordination to any such Subclass.
 
    The 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 Senior  Optimal Amount and  the Class A-4  PO Component Deferred
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 Class B Certificates are entitled
has been reduced to zero as a result of the allocation of losses to the Class  B
Certificates, i.e., the date on which the Class B Percentage has been reduced to
zero  (the "Cross-Over Date"). Prior to such  time, such Realized Losses will be
allocated to  the Subclasses  of Class  B Certificates  sequentially in  reverse
numerical  order,  until the  Class B  Subclass Principal  Balance of  each such
Subclass 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  Subclass  of  Class  B  Certificates  then
outstanding in such  amount as  is necessary  to cause the  sum of  the Class  A
Subclass Principal Balances and the Class B Subclass Principal Balances to equal
the Adjusted Pool Amount.
 
    Allocations to the 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,  the Master Servicer or the Trust Administrator does not advance, (iv)
any interest  shortfalls  or  losses  resulting  from  the  application  of  the
Soldiers'  and Sailors' Civil Relief Act of  1940, as more fully described under
"Certain Legal  Aspects  of the  Mortgage  Loans--Soldiers' and  Sailors'  Civil
Relief Act" in the Prospectus and (v) any interest shortfalls resulting from the
timing  of  the  receipt  of  partial  principal  prepayments  and  net  Partial
Liquidation Proceeds  with respect  to Mortgage  Loans serviced  under the  PHMC
Servicing  Agreement will result from the  priority of distributions of the Pool
Distribution Amount first  to the  the holders of  the Class  A Certificates  as
described above under "--Distributions."
 
    The allocation of the principal portion of Realized Losses in respect of the
Mortgage  Loans  allocated on  or  after the  Cross-Over  Date will  be effected
through the adjustment on any Determination Date of the Class A Non-PO Principal
Balance and the Component Principal Balance  of the Class A-4 PO Component  such
that  (i) the Class A  Non-PO Principal Balance equals  the Adjusted Pool Amount
less the Adjusted Pool Amount (PO Portion) as of the preceding Distribution Date
and (ii) the Component  Principal Balance of the  Class A-4 PO Component  equals
the Adjusted Pool Amount (PO Portion) as of the preceding Distribution Date. The
principal  portion of such Realized Losses allocated to the Class A Certificates
(other than the  Class A-4  Certificates), the Class  A-4 TAC  A Component,  the
Class  A-4  TAC B  Component and  the Class  A-4 TAC  Accrual Component  will be
allocated to  such  outstanding Subclasses  of  Class A  Certificates  and  such
Components pro rata in accordance with their Class A Subclass Principal Balances
or  Component Principal Balances  or, in the  case of the  Class A-4 TAC Accrual
Component, the  initial  Component Principal  Balance,  if lower.  The  interest
portion  of any Realized Loss allocated on  or after the Cross-Over Date will be
allocated among the outstanding Subclasses of  Class A Certificates pro rata  in
accordance  with  their respective  Class A  Subclass Interest  Accrual Amounts,
without regard to any reduction pursuant to this sentence. Any amount  allocated
to  the Class A-4 Certificates will be  allocated among the Class A-4 Components
(other than  the Class  A-4 PO  Component)  pro rata  in accordance  with  their
respective  Component Interest Accrual Amounts,  without regard to any reduction
pursuant to  this  sentence.  Any  such  losses  will  be  allocated  among  the
outstanding  Class A  Certificates within each  Subclass pro  rata in accordance
with their respective Percentage Interests.
 
    Any Excess Special Hazard Losses,  Excess Fraud Losses or Excess  Bankruptcy
Losses  will be  allocated (i)  with respect  to the  principal portion  of such
losses (a)  to  the  outstanding  Subclasses  of  Class  A  Certificates  (other
 
                                      S-50
<PAGE>
than  the Class A-4 Certificates with respect to the Class A-4 PO Component) and
the Class B Certificates pro rata based on their outstanding principal  balances
in  proportion  to the  Non-PO Fraction  of such  losses and  (b) in  respect of
Discount Mortgage Loans, to the Class A-4 Certificates with respect to the Class
A-4 PO Component in proportion to the  PO Fraction of such losses and (ii)  with
respect  to the interest portion of the such  losses, to the Class A and Class B
Certificates pro  rata  based on  the  interest  accrued. (Any  such  losses  so
allocated  to the  Class A Certificates  (other than the  Class A-4 Certificates
with respect  to  the  Class A-4  PO  Component)  will be  allocated  among  the
outstanding  Subclasses  of  Class  A Certificates  (other  than  the  Class A-4
Certificates) and  the  Class  A-4  Components (other  than  the  Class  A-4  PO
Component)  pro rata in accordance with  their then-outstanding Class A Subclass
Principal Balances or Component Principal Balances or, in the case of the  Class
A-4  TAC Accrual Component,  the initial Component  Principal Balance, if lower,
with respect to the principal portion of such losses and their Class A  Subclass
Interest  Accrual  Amounts, without  regard to  any  reduction pursuant  to this
sentence, 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).
 
    The interest portion of  Excess Special Hazard  Losses, Excess Fraud  Losses
and  Excess Bankruptcy Losses will be allocated by reducing the Class A Subclass
Interest Accrual Amounts and Class B Subclass Interest Accrual Amounts.
 
    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 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 then  the percentage of principal payments  on
the  Mortgage Loans to which the holders of the Class A Certificates (other than
the Class A-4 Certificates) and the Class A-4 Certificates to the extent of  the
Class  A-4 TAC A Component, the Class A-4  TAC B Component and the Class A-4 TAC
Accrual Component 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 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,  other than  Excess Special  Hazard Losses,  will be
allocated solely to the Class B Certificates until the Class B Principal Balance
has been reduced to zero. Special Hazard Losses in excess of the Special  Hazard
Loss  Amount are  "Excess Special Hazard  Losses." Excess  Special Hazard Losses
will be allocated among (i) the Class  A Certificates (other than the Class  A-4
PO Component of the Class A-4 Certificates) and Class B Certificates and (ii) to
the  extent such  Excess Special  Hazard Losses  arise with  respect to Discount
Mortgage Loans, the Class A-4 PO Component of the Class A-4 Certificates. If the
aggregate of all Special Hazard Losses incurred in the month preceding the month
of the related Distribution Date (the "Aggregate Current Special Hazard Losses")
is less than  or equal  to the then-applicable  Special Hazard  Loss Amount,  no
Special  Hazard  Losses will  be regarded  as Excess  Special Hazard  Losses. If
Aggregate Current  Special  Hazard  Losses exceed  the  then-applicable  Special
Hazard Loss Amount, a portion of each Special Hazard Loss will be regarded as an
"Excess Special Hazard Loss" in proportion to the ratio of (a) the excess of (i)
Aggregate  Current Special Hazard  Losses over (ii)  the then-applicable Special
Hazard Loss  Amount,  to  (b)  the  Aggregate  Current  Special  Hazard  Losses.
Thereafter,  when the  Special Hazard  Loss Amount  is zero,  all Special Hazard
Losses will be regarded as Excess  Special Hazard Losses. Upon initial  issuance
of the Series 1996-6 Certificates, the "Special Hazard Loss Amount" with respect
thereto  will be equal to approximately  1.01% (approximately $2,143,632) 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  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
 
                                      S-51
<PAGE>
ratings on the  Offered Certificates,  as evidenced  by letters  to that  effect
delivered  by S&P and Fitch to the  Master Servicer and the Trust Administrator.
On and after the Cross-Over Date, the Special Hazard Loss Amount will be zero.
 
    Fraud Losses, other than  Excess Fraud Losses, will  be allocated solely  to
the Class B Certificates until the Class B Principal Balance has been reduced to
zero. Fraud Losses in excess of the Fraud Loss Amount are "Excess Fraud Losses."
Excess  Fraud Losses will be allocated among (i) the Class A Certificates (other
than the Class  A-4 PO  Component of  the Class  A-4 Certificates)  and Class  B
Certificates  and (ii) to the extent such Excess Fraud Losses arise with respect
to Discount  Mortgage  Loans,  the Class  A-4  PO  Component of  the  Class  A-4
Certificates.  If  the  aggregate of  all  Fraud  Losses incurred  in  the month
preceding the month  of the  related Distribution Date  (the "Aggregate  Current
Fraud  Losses") is less than or equal  to the then-applicable Fraud Loss Amount,
no Fraud Losses will  be regarded as Excess  Fraud Losses. If Aggregate  Current
Fraud  Losses exceed  the then-applicable Fraud  Loss Amount, a  portion of each
Fraud Loss will be regarded as an "Excess Fraud Loss" in proportion to the ratio
of (a)  the  excess  of  (i)  Aggregate  Current  Fraud  Losses  over  (ii)  the
then-applicable  Fraud Loss Amount,  to (b) the  Aggregate Current Fraud Losses.
Thereafter, when  the  Fraud Loss  Amount  is zero,  all  Fraud Losses  will  be
regarded  as Excess  Fraud Losses.  Upon initial  issuance of  the Series 1996-6
Certificates, the "Fraud  Loss Amount"  with respect  thereto will  be equal  to
approximately  2.00% (approximately  $4,248,413) 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 Certificates through 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
most recent anniversary  of the  Cut-Off Date  minus (2)  the aggregate  amounts
allocated  solely to the Class B Certificates with respect to Fraud Losses since
the  most  recent  anniversary   of  the  Cut-Off   Date  through  the   related
Determination  Date.  On  and  after  the Cross-Over  Date  or  after  the fifth
anniversary of the Cut-Off Date, the Fraud Loss Amount will be zero.
 
    Bankruptcy Losses, other  than Excess Bankruptcy  Losses, will be  allocated
solely  to the Class B Certificates until the Class B Principal Balance has been
reduced to zero. Bankruptcy losses in  excess of the Bankruptcy Loss Amount  are
"Excess Bankruptcy Losses." Excess Bankruptcy Losses will be allocated among (i)
the Class A Certificates (other than the Class A-4 PO Component of the Class A-4
Certificates)  and  Class B  Certificates  and (ii)  to  the extent  such Excess
Bankruptcy Losses arise with respect to  Discount Mortgage Loans, the Class  A-4
PO  Component of the Class A-4 Certificates.  If the aggregate of all Bankruptcy
Losses incurred in  the month preceding  the month of  the related  Distribution
Date  (the "Aggregate Current Bankruptcy  Losses") is less than  or equal to the
then applicable Bankruptcy Loss Amount, no Bankruptcy Losses will be regarded as
Excess Bankruptcy  Losses. If  Aggregate Current  Bankruptcy Losses  exceed  the
then-applicable  Bankruptcy Loss Amount, a portion  of each Bankruptcy Loss will
be regarded as an "Excess Bankruptcy Loss" in proportion to the ratio of (a) the
excess of (i) Aggregate Current Bankruptcy Losses over (ii) the  then-applicable
Bankruptcy  Loss  Amount,  to  (b)  the  Aggregate  Current  Bankruptcy  Losses.
Thereafter, when the Bankruptcy Loss Amount is zero, all Bankruptcy Losses  will
be  regarded as  Excess Bankruptcy Losses.  Upon initial issuance  of the Series
1996-6 Certificates, the "Bankruptcy Loss  Amount" with respect thereto will  be
equal  to  approximately  0.05%  (approximately $100,000)  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 Certificates  through 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,  if any,  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   Certificates  since  such
anniversary.  The  Bankruptcy  Loss  Amount  and  the  related  coverage  levels
described  above may be  reduced or modified upon  written confirmation from S&P
and Fitch that  such reduction  or modification  will not  adversely affect  the
then-current ratings assigned to the Offered Certificates by S&P and Fitch. Such
a  reduction  or  modification may  adversely  affect the  coverage  provided by
subordination with respect  to Bankruptcy  Losses. On and  after the  Cross-Over
Date, the Bankruptcy Loss Amount will be zero.

    Notwithstanding the foregoing, the provisions relating to subordination will
not be applicable in connection with a Bankruptcy Loss so long as the applicable
Servicer has notified the Trust Administrator and the Master Servicer in writing
that  such  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 such 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 $13,277,250, the risk of Special Hazard Losses,
Fraud Losses  and Bankruptcy  Losses will  be separately  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

Realization Upon Defaulted Mortgage Loans" in the Prospectus.

                      DESCRIPTION OF THE MORTGAGE LOANS(1)
 
GENERAL
 
    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 having  original terms to  stated maturity  of
approximately  20 to 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  809  promissory notes,  to  have an  aggregate unpaid
principal balance as of the Cut-Off Date (the "Cut-Off Date Aggregate  Principal
Balance")  of  approximately  $212,420,663 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.
 
    As of the  Cut-Off Date, it  is expected  that five of  the Mortgage  Loans,
representing approximately 0.16% of the Cut-Off Date Aggregate Principal Balance
of  the Mortgage  Loans, will be  secured by  Co-op Shares. It  is expected that
three of the  Mortgage Loans,  representing approximately 0.31%  of the  Cut-Off
Date  Aggregate Principal Balance of the Mortgage Loans, will be Buy-Down Loans.
No Mortgage Loan was originated pursuant to PHMC's relocation mortgage  program.
See "The Trust Estates--Mortgage Loans" 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.
 
    It is expected that four Mortgage Loans, representing approximately 0.49% of
the Cut-Off Date  Aggregate Principal  Balance of  the Mortgage  Loans, will  be
Subsidy  Loans. See "The Trust Estates--Mortgage Loans" and "PHMC--Mortgage Loan
Underwriting" in the Prospectus.
 
    As of the Cut-Off  Date, each Mortgage  Loan is expected  to have an  unpaid
principal   balance  of  not  less  than  approximately  $24,985  or  more  than
approximately $1,071,817  and  the  average  unpaid  principal  balance  of  the
Mortgage  Loans  is expected  to be  approximately  $262,572. The  latest stated
maturity date of  any of the  Mortgage Loans is  expected to be  April 1,  2026;
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,  769 of  the  Mortgaged Properties,  which  secure
approximately  95.60% of  the Cut-Off  Date Aggregate  Principal Balance  of the
Mortgage Loans, are expected to be  owner occupied primary residences and 40  of
the  Mortgaged Properties, which secure approximately  4.40% of the Cut-Off Date
Aggregate Principal Balance of the Mortgage Loans, are expected to be  non-owner
occupied  or  second  homes.  See  "PHMC--Mortgage  Loan  Underwriting"  in  the
Prospectus.
 
- ------------
(1)  The descriptions in this Prospectus Supplement of the Trust Estate and  the
     properties  securing the Mortgage Loans to  be included in the Trust Estate
     are based upon the  expected characteristics of the  Mortgage Loans at  the
     close  of  business on  the  Cut-Off Date,  as  adjusted for  the scheduled
     principal  payments  due  on  or  before  such  date.  Notwithstanding  the
     foregoing, any of such Mortgage Loans may be excluded from the Trust Estate
     (i)  as a result of  principal prepayment thereof in full  or (ii) if, as a
     result of  delinquencies  or otherwise,  the  Seller otherwise  deems  such
     exclusion necessary or desirable. In either event, other Mortgage Loans may
     be  included in the Trust Estate.  The Seller believes that the information
     set forth  herein  with respect  to  the expected  characteristics  of  the
     Mortgage Loans on the Cut-Off Date is representative of the characteristics
     as  of the Cut- Off Date of the  Mortgage Loans to be included in the Trust
     Estate as it will be constituted at the time the Series 1996-6 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  1996-6  Certificates vary  materially  from those
     described herein, revised information regarding the Mortgage Loans will  be
     made available to purchasers of the Offered 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.
 
                                      S-54

    As of the  Cut-Off Date, there  were 224 Discount  Mortgage Loans having  an
aggregate  unpaid  principal balance  of approximately  $65,560,717, a  range of
unpaid principal balances of approximately $51,571 to approximately $649,506, an
average unpaid principal balance of approximately $292,682, a range of  interest
rates  from 6.750%  to 7.500%  per annum,  a weighted  average interest  rate of
approximately 7.273% per annum, a range of remaining terms to stated maturity of
239 months to 360 months, a  weighted average remaining term to stated  maturity
of  approximately 353 months, a range of original Loan-to-Value Ratios of 33.11%
to 95.00%,  a weighted  average original  Loan-to-Value Ratio  of  approximately
74.33%  and  the  following  geographic  concentration  of  Mortgaged Properties
securing Mortgage Loans  in excess of  5.00% of the  aggregate unpaid  principal
balance  of  the Discount  Mortgage Loans:  approximately 35.31%  in California,
approximately 8.77% in New Jersey, approximately 7.48% in Hawaii,  approximately
6.47% in Connecticut, and approximately 5.21% in Maryland.
 
    As  of the  Cut-Off Date,  there were 585  Premium Mortgage  Loans having an
aggregate unpaid principal  balance of  approximately $146,859,946,  a range  of
unpaid  principal balances of approximately $24,985 to approximately $1,071,817,
an average  unpaid  principal balance  of  approximately $251,043,  a  range  of
interest  rates from 7.50% to 11.25% per annum, a weighted average interest rate
of approximately 7.941% per annum, a range of remaining terms to stated maturity
of 233  months  to 360  months,  a weighted  average  remaining term  to  stated
maturity  of approximately 356 months, a  range of original Loan-to-Value Ratios
of 15.38%  to  95.00%,  a  weighted  average  original  Loan-to-Value  Ratio  of
approximately  75.82% and  the following  geographic concentration  of Mortgaged
Properties securing Mortgage Loans  in excess of 5.00%  of the aggregate  unpaid
principal  balance of  the Mortgage  Loans other  than Discount  Mortgage Loans:
approximately  37.19%   in  California;   approximately  8.60%   in  New   York,
approximately 6.73% in New Jersey and approximately 5.11% in Florida.
 
    The  Mortgage Loans have been acquired by the Seller from PHMC. The Mortgage
Loans that PHMC sells to the Seller  will have been either orginated by PHMC  or
acquired by PHMC from various entities (each, a "PHMC Loan Seller") which either
originated  the  Mortgage  Loans  or acquired  the  Mortgage  Loans  pursuant to
mortgage  loan  purchase   programs  operated   by  such   PHMC  Loan   Sellers.
Approximately  96.11%  (by  Cut-Off  Date Aggregate  Principal  Balance)  of the
Mortgage Loans  (the "PHMC  Underwritten Loans")  were generally  originated  in
conformity  with  PHMC's underwriting  standards applied  either  by PHMC  or by
eligible originators to whom PHMC  had delegated all underwriting functions.  In
certain  instances, exceptions  to PHMC's  underwriting standards  may have been
granted by PHMC to such  originators. See "PHMC--Mortgage Loan Underwriting"  in
the  Prospectus.  Approximately  0.54%  (by  Cut-Off  Date  Aggregate  Principal
Balance) of the  Mortgage Loans  (the "Pool  Certification Underwritten  Loans")
will  have  been reviewed  by  UGRIC to  ensure  compliance with  such company's
credit,  appraisal  and  underwriting  standards.  Neither  the  Series   1996-6
Certificates  nor the Mortgage Loans are  insured or guaranteed under a mortgage
pool insurance policy issued by UGRIC. The Pool Certification Underwritten Loans
were evaluated by PHMC using enhanced credit scoring ("ECS") as described in the
Prospectus under  "PHMC-- Mortgage  Loan  Underwriting" and,  based on  the  ECS
scores  of such Mortgage Loans, some of such Mortgage Loans were re-underwritten
by PHMC. The remaining  approximate 3.35% (by  Cut-Off Date Aggregate  Principal
Balance)  of the  Mortgage Loans (the  "Bulk Purchase  Underwritten Loans") will
have been  underwritten under  varying standards  which have  been reviewed  and
accepted  by PHMC. Neither the Seller nor  PHMC has underwritten any of the Bulk
Purchase Underwritten Loans. See  "--Mortgage Underwriting Standards" below  and
"PHMC-- Mortgage Loan Underwriting" in the Prospectus.
 
    As  of  March  8, 1996,  as  a  result of  recent  flooding  (the "Northeast
Floods"), all counties in the Commonwealth of Pennsylvania, all counties in  the
State of Maryland, 28 counties in the State of West Virginia, 28 counties in the
State  of New York, 13 counties in  the Commonwealth of Virginia and 12 counties
in the State  of Ohio  (the "Northeast  Flood Counties")  were declared  federal
disaster  areas eligible for federal disaster assistance. It is expected that 48
Mortgage Loans, representing approximately 6.42%  of the Cut-Off Date  Aggregate
Principal Balance of the Mortgage Loans, will be secured by Mortgaged Properties
that  are located in  the Northeast Flood Counties.  In addition, other counties
may have been affected by the Northeast Floods. Neither the Seller nor PHMC  has
undertaken  the physical  inspection of any  Mortgaged Properties.  As a result,
there can be no assurance that material damage to any Mortgaged Property in  the
affected region has not occurred.
 
    As  of February  28, 1996,  as a result  of recent  flooding (the "Northwest
Floods"), 26  counties in  the State  of Oregon,  21 counties  in the  State  of
Washington  and  10  counties  in  the  State  of  Idaho  (the  "Northwest Flood
Counties") were declared  federal disaster areas  eligible for federal  disaster
assistance. It is expected that 17
 
                                      S-55
<PAGE>
Mortgage  Loans, representing approximately 1.91%  of the Cut-Off Date Aggregate
Principal Balance of the Mortgage Loans, will be secured by Mortgaged Properties
that are located in  the Northwest Flood Counties.  In addition, other  counties
may  have been affected by the Northwest Floods. Neither the Seller nor PHMC has
undertaken the physical  inspection of  any Mortgaged Properties.  As a  result,
there  can be no assurance that material damage to any Mortgaged Property in the
affected region has not occurred.
 
    In the  Pooling  and Servicing  Agreement,  the Seller  will  represent  and
warrant that, as of the date of issuance of the Certificates, each Mortgage Loan
is  undamaged by  flood, water, fire,  earthquake or  earth movement, windstorm,
tornado or similar casualty (excluding  casualty from the presence of  hazardous
wastes  or hazardous substances, as to which the Seller makes no representation)
so as to adversely affect the value  of such Mortgaged Property as security  for
such  Mortgage Loan  or the use  for which  such premises were  intended. In the
event of a breach of such  representation with respect to a Mortgaged  Property,
including  by  virtue  of  the  Northeast  Floods  and  Northwest  Floods, which
materially and  adversely affects  the interests  of Certificateholders  in  the
related  Mortgage Loan, the Seller will be obligated to repurchase or substitute
for  such  Mortgage  Loan,  as  described  under  "The  Trust  Estates--Mortgage
Loans--Representations and Warranties" in the Prospectus. Repurchase of any such
Mortgage  Loan will  affect in varying  degrees the yields  and weighted average
lives of the  Subclasses of Offered  Certificates and may  adversely affect  the
yield of any Offered Certificates purchased at a premium.

    As  of the Cut-Off Date, the weighted  average Mortgage Interest Rate of the
Mortgage Loans  is  expected to  be  approximately  7.735% per  annum.  The  Net
Mortgage  Interest Rate  of each  Mortgage Loan  will be  equal to  the Mortgage
Interest Rate  for  such Mortgage  Loan  minus the  sum  of (a)  the  applicable
Servicing  Fee Rate and  (b) the Master Servicing  Fee Rate as  set forth in the
Pooling and Servicing Agreement.  As of the Cut-Off  Date, the weighted  average
Net Mortgage Interest Rate of the Mortgage Loans is expected to be approximately
7.508% per annum.

    As of the  Cut-Off Date,  the minimum  and maximum  Loan-to-Value Ratios  at
origination  of  the  Mortgage  Loans  are expected  to  be  15.38%  and 95.00%,
respectively, and the weighted average Loan-to-Value Ratio at origination of the
Mortgage Loans is expected to  be approximately 75.36%. The Loan-to-Value  Ratio
of  a Mortgage Loan is calculated using the lesser of (i) the appraised value of
the related Mortgaged Property, as established  by an appraisal obtained by  the
originator  from an appraiser at the time of origination and (ii) the sale price
for such property. See "The Trust Estates--Mortgage Loans" in the Prospectus. It
is expected  that  65 of  the  Mortgage  Loans having  Loan-to-Value  Ratios  at
origination  in excess of 80%, representing approximately 8.41% (by Cut-Off Date
Aggregate Principal  Balance) of  the Mortgage  Loans, were  originated  without
primary mortgage insurance.

    As of the Cut-Off Date, the average unpaid principal balance of the Mortgage
Loans is expected  to be  approximately $262,572. As  of the  Cut-Off Date,  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 are expected to be approximately 64.37%
and  75.46%,  respectively.  See  "The  Trust  Estates--Mortgage  Loans"  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 1996-6
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 equal to 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 Master Servicer 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 Purchases"
in the Prospectus. A Servicer may, in its sole discretion, allow the  assumption
of  a defaulted Mortgage  Loan serviced by  such Servicer 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.
 
MORTGAGE UNDERWRITING STANDARDS
 
    Approximately  96.11% (by Cut-Off  Date Aggregate Principal  Balance) of the
Mortgage Loans  (the "PHMC  Underwritten Loans")  were generally  originated  in
conformity  with PHMC's underwriting standards. In  the case of certain Mortgage
Loans underwritten  pursuant to  a  Delegated Underwriting  (as defined  in  the
Prospectus  under "PHMC--Mortgage Loan Underwriting") arrangement, exceptions to
PHMC's  underwriting   standards   may  have   been   approved  by   PHMC.   See
"PHMC--Mortgage Loan Underwriting" in the Prospectus.
 
    Approximately  0.54% (by  Cut-Off Date  Aggregate Principal  Balance) of the
Mortgage Loans will have been reviewed  by UGRIC to ensure compliance with  such
company's  credit, appraisal and underwriting  standards generally to assess the
eligibility of  such Mortgage  Loans for  inclusion  in a  mortgage pool  to  be
insured   by  such  company.  See  "PHMC--Mortgage  Loan  Underwriting"  in  the
Prospectus.
 
    Neither the Series 1996-6 Certificates nor the Mortgage Loans are insured or
guaranteed under a mortgage pool insurance policy issued by UGRIC.
 
    The Pool  Certification  Underwritten Loans  were  evaluated by  PHMC  using
enhanced   credit  scoring  ("ECS")   as  described  in   the  Prospectus  under
"PHMC--Mortgage Loan Underwriting" and, based on the ECS scores of such Mortgage
Loans, some of such Mortgage Loans were re-underwritten by PHMC.
 
    The  remaining  approximate  3.35%  (by  Cut-Off  Date  Aggregate  Principal
Balance)  of the  Mortgage Loans (the  "Bulk Purchase  Underwritten Loans") will
have been underwritten under varying standards. A certain percentage of the Bulk
Purchase Underwritten  Loans might  not have  qualified initially  under  PHMC's
underwriting   standards,   in   most  cases   because   the   loan-to-value  or
debt-to-income ratio exceeded PHMC's thresholds. However, PHMC has in each  case
reviewed  the underwriting standards applied  and determined that such variances
were  justifiable  or  did  not  depart  materially  from  PHMC's   underwriting
standards.
 
                  PHMC 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")  and 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
"PHMC--Mortgage  Loan Production Sources" and  "--Mortgage Loan Underwriting" 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
Buy-Down Loans and Balloon Loans, will be representative of the results that may
be experienced with  respect to  the Mortgage  Loans generally  or the  Mortgage
Loans  serviced by PHMC. Furthermore, there can  be no assurance that the future
experience on the Mortgage  Loans generally (or the  Mortgage Loans serviced  by
PHMC), all of which are fixed interest rate mortgage loans having original terms
to  stated maturity  of approximately 20  or 30 years,  approximately 13.61% (by
Cut-Off Date  Aggregate  Principal  Balance)  of which  are  serviced  by  Other
Servicers  and approximately 0.54% (by Cut-Off Date Aggregate Principal Balance)
of which were underwritten to a pool insurer's standards, will be comparable  to
that of the total Program Loans or Fixed Program Loans.

    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
serviced  by PHMC contained in the Trust Estate, all of which are fixed interest
rate mortgage loans having original terms to stated maturity of approximately 20
or 30 years and none of which are Relocation Mortgage Loans, will be  comparable
to  that  of the  total  Program Loans,  the Fixed  Program  Loans or  the Fixed
Non-relocation Program Loans.
 
    The  following  tables  reflect  delinquency,  foreclosure  and  loan   loss
experience  of mortgage loans serviced by PHMC. As described under "Risk Factors
and Special Considerations--Recent Developments," PHMC  intends, as of the  Sale
Date,  to cease  its mortgage loan  origination and  servicing business. Norwest
Mortgage,  as  subservicer  for  PHMC,   will  perform  foreclosure  and   other
realization   activities  in  connection  with   defaulted  Mortgage  Loans  and
Prudential  Asset  Recovery,  Inc.  or  another  third  party  contractor   will
administer and dispose of real estate acquired upon foreclosure.
 
    In addition, the following tables reflect rapid growth during recent periods
in  PHMC's mortgage  loan servicing portfolio  as a result  of the substantially
higher volume of new loan  originations and acquisitions of recently  originated
mortgage  loans.  Delinquencies,  foreclosures  and  loan  losses  generally are
expected to occur  more frequently  after the  first full  year of  the life  of
mortgage  loans. Accordingly, because a large  number of mortgage loans serviced
by PHMC  have been  originated  recently, the  current level  of  delinquencies,
foreclosures  and loan losses may not be  representative of the levels which may
be experienced over the lives of such  mortgage loans. Because on the Sale  Date
PHMC  intends to cease  the mortgage loan  origination and acquisition business,
the levels  of delinquencies,  foreclosures and  loan losses  as percentages  of
PHMC's  total  servicing  portfolio  could rise  significantly  above  the rates
indicated in the following tables.

(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

    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.
Furthermore, the level  of foreclosures reported  is affected by  the length  of
time  legally required to complete the foreclosure process and take title to the
related property, which varies from jurisdiction to jurisdiction. The changes in
the delinquency,  foreclosure  and  loan loss  experience  of  PHMC's  servicing
portfolio   during  the  periods  set  forth  in  the  preceding  table  may  be
attributable to factors such as those described above, although there can be  no
assurance as to whether 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  serviced by  PHMC may  be particularly  affected to  the
extent  that the  related Mortgaged Properties  are concentrated  in areas which
experience adverse  economic conditions  or declining  real estate  values.  See
"Description of the Mortgage Loans" in the Prospectus Supplement.
 
                      PREPAYMENT AND YIELD CONSIDERATIONS
 
    The  rate  of distributions  in reduction  of the  principal balance  of any
Subclass of Offered Certificates, the  aggregate amount of distributions on  any
Subclass  of Offered Certificates and  the yield to maturity  of any Subclass of
Offered Certificates purchased at a discount or premium will be directly related
to the rate of payments  of principal on the Mortgage  Loans 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  and optional purchases by the Master Servicer of all of the Mortgage
Loans in connection with the termination  of the Trust Estate. See  "Description
of  the Mortgage Loans--Mandatory Repurchase  or Substitution of Mortgage Loans"
and "Pooling  and Servicing  Agreement--Optional  Termination" herein  and  "The
Trust  Estates--Mortgage Loans--Assignment of Mortgage Loans to the Trustee" and
"--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 extent  of the Non-PO Fraction,  to
the  holders of the Class A Certificates  (other than the Class A-4 Certificates
with respect to the  Class A-4 PO Component)  then entitled to distributions  in
respect  of principal during the nine  years beginning on the first Distribution
Date, and, to the extent that such principal prepayments are made in respect  of
a  Discount Mortgage Loan,  to the Class  A-4 Certificates in  proportion to the
interest of the Class  A-4 PO Component  of the Class  A-4 Certificates in  such
Discount  Mortgage Loan represented  by the PO  Fraction. 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 Offered  Certificates
or   the  aggregate  amount   of  distributions  on   any  Subclass  of  Offered
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 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
 
                                      S-69
<PAGE>
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), servicers  (including PHMC) and
mortgage  loan  brokers  to  encourage  refinancing  through  such  originators,
servicers  and  brokers,  including, but  not  limited to,  general  or targeted
solicitations (which may be based on characteristics including, but not  limited
to,  the  mortgage loan  interest  rate or  payment  history and  the geographic
location of the Mortgaged Property), reduced origination fees or closing  costs,
pre-approved  applications, waiver of pre-closing  interest accrued with respect
to a refinanced  loan prior  to the  pay-off of  such loan,  or other  financial
incentives.  See "Prepayment and Yield  Considerations--Weighted Average Life of
Certificates" in the Prospectus.  In addition, PHMC or  third parties may  enter
into  agreements with borrowers providing for the bi-weekly payment of principal
and interest on the related mortgage  loan, thereby accelerating payment of  the
mortgage loan resulting in partial prepayments.
 
    Other  factors  affecting prepayment  of mortgage  loans include  changes in
mortgagors' housing  needs,  job transfers,  unemployment  or, in  the  case  of
self-employed mortgagors or mortgagors relying on commission income, substantial
fluctuations  in income, significant declines in  real estate values and adverse
economic  conditions  either  generally  or  in  particular  geographic   areas,
mortgagors'  equity in the Mortgaged Properties,  including the use of second or
"home equity"  mortgage loans  by mortgagors  or the  use of  the properties  as
second  or  vacation homes,  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 Offered 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 1996-6 Certificates.  See "Prepayment  and Yield  Considerations" in  the
Prospectus.
 
    THE  YIELD  TO MATURITY  OF THE  OFFERED CERTIFICATES  WILL BE  SENSITIVE IN
VARYING DEGREES  TO  THE  RATE  AND  TIMING  OF  PRINCIPAL  PAYMENTS  (INCLUDING
PREPAYMENTS,  WHICH MAY  BE MADE  AT ANY TIME  WITHOUT PENALTY)  ON THE MORTGAGE
LOANS. 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.  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 FOR  INVESTORS PURCHASING
OFFERED CERTIFICATES AT A PREMIUM. INVESTORS PURCHASING OFFERED CERTIFICATES  AT
A PREMIUM SHOULD ALSO CONSIDER THE RISK THAT A RAPID RATE OF PAYMENTS IN RESPECT
OF  PRINCIPAL (INCLUDING PREPAYMENTS) ON THE  MORTGAGE LOANS COULD RESULT IN THE
FAILURE OF SUCH INVESTORS TO FULLY RECOVER THEIR INITIAL INVESTMENTS.
 
    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  an Offered 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 Offered 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  Offered Certificates may  be affected by  the
geographic  concentration  of  the Mortgaged  Properties  securing  the Mortgage
Loans. In recent  periods, California and  several other regions  in the  United
States  have experienced  significant declines  in housing  prices. In addition,
California  and  several  other  regions  have  experienced  natural  disasters,
including  earthquakes,  floods  and  hurricanes,  which  may  adversely  affect
property values. Any deterioration in housing  prices in California, as well  as
New York, New Jersey and the
 
                                      S-70
<PAGE>
other   states  in  which   the  Mortgaged  Properties   are  located,  and  any
deterioration of economic conditions in such states 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 have
an adverse effect on the yield to maturity of the Offered 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 Offered
Certificates. An investor is urged to  make an investment decision with  respect
to  any  Subclass of  Offered  Certificates based  on  the anticipated  yield to
maturity of such Subclass  of Offered Certificates  resulting from its  purchase
price  and such  investor's own  determination as  to anticipated  Mortgage Loan
prepayment rates under a variety of scenarios. The extent to which any  Subclass
of  Offered Certificates are purchased at a discount or a premium and the degree
to which such Subclass is sensitive to the timing of prepayments will  determine
the  extent to which  the yield to maturity  of such Subclass  may vary from the
anticipated yield. An investor should  carefully consider the associated  risks,
including,  in the case of  any Subclass of Offered  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 Subclass of  Offered
Certificates purchased at a premium the risk that a faster than anticipated rate
of  principal payments could result in an  actual yield to such investor that is
lower than the anticipated yield.
 
    An investor should consider the risk that rapid rates of prepayments on  the
Mortgage Loans, and therefore of amounts distributable in reduction of principal
balance of the Offered 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  Offered 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  Offered  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.
 
    As indicated under "Federal Income Tax Considerations" herein, the Class A-R
and  Class A-LR Certificateholders'  REMIC taxable income  and the tax liability
thereon may exceed,  and may  substantially 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  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 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, OR MAY BE NEGATIVE.
 
    As  referred to herein, the  weighted average life of  a Subclass of Offered
Certificates refers to the average amount of time that will elapse from the date
of issuance of  such Subclass until  each dollar in  reduction of the  principal
balance  of such Subclass  is distributed to the  investor. The weighted average
life of each Subclass of Offered 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, prepayments or other recoveries of
principal.
 
    THE  WEIGHTED  AVERAGE LIFE  OF THE  COMPANION  CERTIFICATES WILL  BE HIGHLY
SENSITIVE TO  THE RATE  OF  PRINCIPAL PAYMENTS  (INCLUDING PREPAYMENTS)  ON  THE
MORTGAGE  LOANS.  Specifically, if  prepayments result  in  a Class  A Principal
Amount equal to or less than the sum  of the Class A-6 Priority Amount, the  PAC
Principal  Amounts and the  TAC Principal Amounts on  any Distribution Date, the
Companion Certificates will receive no  distributions in reduction of  principal
on  such  Distribution  Date.  Further,  on each  Distribution  Date  up  to and
including the Distribution Date on which the Class A Subclass Principal  Balance
of  the Companion Certificates is reduced to zero, any Excess Principal Payments
over the TAC Principal Amounts for such Distribution Date will be applied to the
Companion Certificates before being distributed to the TAC Certificates, the TAC
Components and the PAC Certificates in the proportions and priorities set  forth
above    under   "Description   of    the   Certificates--Principal   (Including
Prepayments)."  See  "Description  of  the  Certificates--Principal   (Including
Prepayments)--Principal Payment Characteristics of the PAC Certificates, the TAC
Certificates, the TAC Components and the Companion Certificates" herein.

    Prepayments on mortgage loans are commonly measured relative to a prepayment
standard  or model. The  model used in this  Prospectus Supplement, the Standard
Prepayment Assumption ("SPA"),  represents an  assumed rate  of prepayment  each
month  relative  to the  then outstanding  principal  balance of  a pool  of new
mortgage loans. A prepayment assumption of 100% SPA assumes constant  prepayment
rates  of  0.2% per  annum of  the  then outstanding  principal balance  of such
mortgage loans in  the first  month of  the life of  the mortgage  loans and  an
additional  0.2% per annum  in each month thereafter  until the thirtieth month.
Beginning in the thirtieth month and in each month thereafter during the life of
the mortgage loans, 100% SPA assumes a constant prepayment rate of 6% per  annum
each month. As used in the tables below, "0% SPA" assumes prepayment rates equal
to  0%  of  SPA,  I.E.,  no  prepayments.  Correspondingly,  "175%  SPA" assumes
prepayment rates equal to 175% 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 remaining term to maturity, (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  May
1996, (iii) the Seller does not repurchase any Mortgage Loan, as described under
"Description  of the  Mortgage Loans--  Mandatory Repurchase  or Substitution of
Mortgage Loans" herein, and the Master Servicer does not exercise its option  to
purchase the Mortgage Loans and thereby cause a termination of the Trust Estate,
(iv) principal prepayments in full on the Mortgage Loans will be received on the
last  day of  each month  commencing in  April 1996  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 20 or 30
years, (vi) the Series 1996-6 Certificates will be issued on April 29, 1996  and
(vii)  distributions to Certificateholders will be made  on the 25th day of each
month, commencing in  May 1996. IT  IS HIGHLY UNLIKELY  THAT THE MORTGAGE  LOANS
WILL  PREPAY AT ANY CONSTANT RATE, THAT ALL OF THE MORTGAGE LOANS WILL PREPAY AT
THE SAME RATE  OR THAT THE  MORTGAGE LOANS  WILL NOT EXPERIENCE  ANY LOSSES.  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
assumed  to be included, as  described above. Any difference  may have an effect
upon the actual percentages of initial Class A Subclass Principal Balance of the
Subclasses of Class  A Certificates, the  actual weighted average  lives of  the
Subclasses  of Class A Certificates  and the date on  which the Class A Subclass
Principal Balance of any Subclass of Class A Certificates is reduced to zero.
 
    Based upon  the foregoing  assumptions, the  following tables  indicate  the
weighted  average life of  each Subclass of Offered  Certificates, and set forth
the percentages of the initial Class  A Subclass Principal Balance of each  such
Subclass  that would be  outstanding after each  of the dates  shown at constant
percentages of SPA presented.

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

    Interest accrued on the Class A  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 Offered Certificates will be less than the yield otherwise produced by their
respective Pass-Through  Rates and  the prices  at which  such 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).
 
                        POOLING AND SERVICING AGREEMENT
 
GENERAL
 
    The  Series 1996-6  Certificates will  be issued  pursuant to  a Pooling and
Servicing Agreement to be dated as of the date of initial issuance of the Series
1996-6 Certificates (the  "Pooling and Servicing  Agreement") among the  Seller,
the  Master Servicer, the Trust Administrator 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 1996-6
Certificates. See "Description of the Certificates," "Servicing of the  Mortgage
Loans" and "The Pooling and Servicing Agreement" in the Prospectus.
 
    The  Trust Estate  created pursuant to  the Pooling  and Servicing Agreement
will consist of (i)  the Mortgage Loans as  described under "Description of  the
Mortgage  Loans,"  (ii) such  assets  as from  time  to time  are  identified as
deposited in any account held for  the benefit of the Certificateholders,  (iii)
any  Mortgaged  Properties  acquired  on  behalf  of  the  Certificateholders by
foreclosure or  by  deed in  lieu  of foreclosure  after  the date  of  original
issuance  of the Certificates and (iv) the  rights of the Trust Administrator to
receive the proceeds of  all insurance policies and  performance bonds, if  any,
required to be maintained pursuant to the Pooling and Servicing Agreement.
 
DISTRIBUTIONS
 
    Distributions  (other than the final distribution in retirement of the Class
A Certificates of each Subclass) will be made by check mailed to the address  of
the  person entitled thereto as it appears on the Certificate Register. However,
with respect  to any  holder of  an Offered  Certificate evidencing  at least  a
$5,000,000  initial  principal  balance,  distributions  will  be  made  on  the
Distribution Date by wire transfer in immediately available funds, provided that
the Master  Servicer,  or  the paying  agent  acting  on behalf  of  the  Master
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 Subclass  or Class of Offered Certificates will
be made only upon presentation and  surrender of the related Certificate at  the
office or agency appointed by the Trust Administrator specified in the notice of
final distribution with respect to the related Subclass or Class.
 
    Unless  Definitive Certificates  are issued  as described  above, the Master
Servicer and  the  Trust Administrator  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   Trust
Administrator  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
1996-6 Certificates evidencing specified Voting  Interests in the Trust  Estate,
the  holders of  the Class  A Certificates  will collectively  be entitled  to a
percentage (the  "Class A  Voting Interest")  of the  aggregate Voting  Interest
represented  by  all Series  1996-6 Certificates  equal  to the  sum of  (A) the
product of  (i)  the then  applicable  Class A  Percentage  and (ii)  the  ratio
obtained  by dividing the Pool  Balance (Non-PO Portion) by  the sum of the Pool
Balance (Non-PO Portion) and the Pool  Balance (PO Portion) (the "Non-PO  Voting
Interest")  and (B) the Pool Balance (PO Portion) divided by the sum of the Pool
Balance (Non-PO Portion) and  the Pool Balance (PO  Portion) and the holders  of
the  Class B Certificates  will collectively be  entitled to the  balance of the
aggregate Voting Interest  represented by  all Series  1996-6 Certificates.  The
aggregate  Voting Interests of each Subclass of Class A Certificates on any date
will be equal to  the product of (a)  99% of the portion  of the Class A  Voting
Interest  on such  date represented  by clause  (A) above  and (b)  the fraction
obtained by dividing  the Class A  Subclass Principal Balance  of such  Subclass
less, in the case of the Class A-4 Certificates, the Component Principal Balance
of  the Class  A-4 PO  Component on such  date by  the Class  A Non-PO Principal
Balance on such date. In addition to
 
                                      S-75
<PAGE>
the Voting Interest of the Class A-4 Certificates determined in accordance  with
the  preceding  sentence  the Class  A-4  Certificates  will be  entitled  to an
additional 1% of the Class A Voting Interest represented by clause (A) above and
the  Class   A  Voting   Interest  represented   by  clause   (B)  above.   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  1996-6 Certificates  will  be  Firstar  Trust
Company,  a  banking  corporation organized  under  the laws  of  Wisconsin. The
Trustee is  located  at 615  East  Michigan  Street, Lewis  Center,  4th  Floor,
Milwaukee,  Wisconsin 53202. The Trustee will  be responsible for monitoring the
compliance of  the  Master Servicer  and  each  Servicer with  the  Pooling  and
Servicing Agreement and the Servicing Agreements. See "The Pooling and Servicing
Agreement--The Trustee" in the Prospectus.
 
TRUST ADMINISTRATOR
 
    First Bank National Association, a national banking association, will act as
Trust  Administrator  for the  Series 1996-6  Certificates. The  corporate trust
office of the Trust Administrator is located at 180 East Fifth Street, St. Paul,
Minnesota 55101.  The Trust  Administrator will  perform certain  administrative
functions  on behalf of  the Trustee and  will act as  the initial paying agent,
certificate registrar and custodian. In addition, the Trust Administrator  will,
in  certain circumstances, be required to make certain advances on or before the
related Distribution Date for  the benefit of the  holders of the Series  1996-6
Certificates. See "Description of the Certificates--Periodic Advances" herein.
 
MASTER SERVICER
 
    SASCOR  will act  as "Master  Servicer" of the  Mortgage Loans  and, in that
capacity, will supervise the  servicing of the  Mortgage Loans, provide  certain
reports  to  the  Trust  Administrator  regarding  the  Mortgage  Loans  and the
Certificates, make Periodic Advances to the limited extent described herein with
respect to the Mortgage  Loans if a  Servicer fails to  make a Periodic  Advance
required  by the related Servicing Agreement,  and service Mortgage Loans in the
event a Servicer is  terminated and a successor  servicer is not appointed.  The
Master  Servicer will  be entitled to  a "Master Servicing  Fee" payable monthly
equal to the product of (i) 1/12th of a fixed percentage per annum as set  forth
in  the Pooling  and Servicing Agreement  (the "Master Servicing  Fee Rate") and
(ii) the aggregate Scheduled Principal Balances of the Mortgage Loans as of  the
first  day  of  each month.  The  Master  Servicer will  pay  all administrative
expenses of  the  Trust  Estate  subject to  reimbursement  as  described  under
"Servicing of the Mortgage Loans" in the Prospectus.
 
    On  the Sale  Date Norwest Bank  will succeed  to all of  the obligations of
SASCOR, as Master Servicer. See "Risk Factors and Special Considerations--Recent
Developments."
 
SPECIAL SERVICING AGREEMENTS
 
    The Pooling and Servicing Agreement may permit the Master Servicer to  enter
into  a special servicing agreement with an unaffiliated holder of a Subclass of
Class B Certificates or of a  class of securities representing interests in  the
Class   B   Certificates   and/or  other   subordinated   mortgage  pass-through
certificates. Pursuant to such an agreement, such holder may instruct the Master
Servicer to instruct  the Servicers, to  the extent provided  in the  applicable
Servicing Agreement to commence or delay foreclosure proceedings with respect to
delinquent Mortgage Loans. Such commencement or delay at such holder's direction
will be taken by the Master Servicer only after such holder deposits a specified
amount  of  cash with  the  Master Servicer.  Such  cash will  be  available for
distribution to Certificateholders  if Liquidation Proceeds  are less than  they
otherwise  may  have  been had  the  Servicers  acted pursuant  to  their normal
servicing procedures.
 
                                      S-76
<PAGE>
OPTIONAL TERMINATION
 
    At its option, the Master Servicer may purchase from the Trust Estate all of
the Mortgage Loans,  and thereby effect  early retirement of  the Series  1996-6
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   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 (including any Mortgaged Property title to  which
has  been acquired by the Trust Estate ("REO Property")) in the Trust Estate and
(ii) the aggregate fair market value of the Trust Estate's assets plus, in  each
case, accrued interest. In the event the Trust Estate is liquidated as described
above,  holders of  the Certificates,  to the  extent funds  are available, will
receive the unpaid principal balance of  their Certificates and any accrued  and
unpaid  interest  thereon.  The amount,  if  any, remaining  in  the Certificate
Account after the payment of all principal and interest on the Certificates  and
expenses of the Upper-Tier REMIC and Lower-Tier REMIC will be distributed to the
holders   of  the  Class  A-R  Certificate   and  the  Class  A-LR  Certificate,
respectively. See  "Description of  the Certificates--Additional  Rights of  the
Class  A-R  and  Class  A-LR Certificateholders"  herein  and  "The  Pooling and
Servicing Agreement--Termination; Purchase of Mortgage Loans" in the Prospectus.
 
                        SERVICING OF THE MORTGAGE LOANS
 
    PHMC will service approximately 86.39% (by Cut-Off Date Aggregate  Principal
Balance)  of  the Mortgage  Loans  and the  servicers  listed below  (the "Other
Servicers", and  collectively  with  PHMC, the  "Servicers")  will  service  the
balance  of  the  Mortgage Loans,  as  indicated,  each pursuant  to  a separate
Servicing Agreement. The  rights to enforce  the related Servicer's  obligations
under  each Servicing Agreement with respect  to the related Mortgage Loans will
be assigned to the  Trustee for the benefit  of Certificateholders. Among  other
things,  the  Servicers are  obligated  under certain  circumstances  to advance
delinquent payments  of principal  and  interest with  respect to  the  Mortgage
Loans. See "Servicing of the Mortgage Loans" in the Prospectus.

CUSTODIAL ACCOUNTS
 
    Each Servicer is required to establish and maintain a custodial account  for
principal and interest (each such account, a "Custodial Account"), into which it
will  deposit all collections of  principal (including principal prepayments and
Liquidation Proceeds in respect of principal, if any) on any Mortgage Loan  that
such  Servicer services, interest  (net of Servicing Fees)  on any Mortgage Loan
that such Servicer services, related insurance proceeds, advances made from  the
Servicer's own funds and the proceeds of any purchase of a related Mortgage Loan
for  breach of a representation or warranty  or the sale of a Mortgaged Property
in connection  with liquidation  of  the related  Mortgage Loan.  All  Custodial
Accounts are required to be held in a depository institution and invested in the
manner  specified in  the related  Servicing Agreement.  Funds in  such accounts
generally must be held separate  and apart from the  assets of the Servicer  and
generally  may not be commingled  with funds held by  a Servicer with respect to
mortgage loans other than the Mortgage Loans.
 
    Not later than the Remittance Date, the Servicers are obligated to remit  to
the  Master Servicer Custodial  Account all amounts on  deposit in the Custodial
Accounts as  of  the  close  of  business on  the  business  day  preceding  the
Remittance Date other than the following:
 
        (a)   amounts  received  as  late  payments  of  principal  or  interest
    respecting which such Servicer previously has made one or more  unreimbursed
    Periodic Advances;
 
        (b)  any unreimbursed Periodic Advances of such Servicer 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 where
    applicable in respect of Prepayment  Interest Shortfalls as described  under
    "Description of the Certificates--Interest";
 
        (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  partial  principal
    prepayments on Mortgage Loans serviced  by Other Servicers 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  (other than Partial Liquidation Proceeds with respect to Mortgage
    Loans serviced by PHMC), received by such Servicer on or after the Due  Date
    occurring in the month in which such Distribution Date occurs, all principal
    prepayments  in full, partial principal  prepayments and Partial Liquidation
    Proceeds on Mortgage Loans  serviced by PHMC, received  by PHMC 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)   all amounts  representing certain  expenses reimbursable  to  such
    Servicer  and any other amounts permitted to be retained by such Servicer or
    withdrawn by  such  Servicer from  the  Custodial Account  pursuant  to  the
    applicable Servicing Agreement;
 
        (g)  all amounts in the nature of late fees, assumption fees, prepayment
    fees and  similar  fees  which  such  Servicer  is  entitled  to  retain  as
    additional servicing compensation;
 
        (h)  reinvestment  earnings  on  payments  received  in  respect  of the
    Mortgage Loans  or on  other amounts  on deposit  in the  related  Custodial
    Account; and
 
        (i)   proceeds received in connection with the liquidation of a Mortgage
    Loan serviced by any Other Servicer in any month prior to the month in which
    such Mortgage Loan becomes a Liquidated  Loan (other than any such  proceeds
    with  respect to a Mortgage Loan that  became a Liquidated Loan in the month
    prior to the month in which such Remittance Date occurs).
 
SERVICING COMPENSATION AND PAYMENT OF EXPENSES
 
    The primary compensation payable to each  of the Servicers is the  aggregate
of  the Servicing Fees  applicable to the related  Mortgage Loans. The Servicing
Fee applicable to  each Mortgage Loan  is expressed as  a fixed percentage  (the
"Servicing  Fee Rate") of the Scheduled  Principal Balance of such Mortgage Loan
as of the first day of each month. The Servicing Fee Rate for each Mortgage Loan
will be a fixed  percentage rate per  annum. The Servicing Fee  Rate, as of  the
Cut-Off  Date,  is expected  to range  from approximately  0.200% to  0.250% per
annum.
 
                                      S-78
<PAGE>
In addition to the Servicing Fees,  late payment fees, loan assumption fees  and
prepayment  fees with respect to  the Mortgage Loans, and  any interest or other
income earned  on  collections  with  respect  to  the  Mortgage  Loans  pending
remittance to the Master Servicer Custodial Account, will be paid to or retained
by  the  Servicers  as  additional Servicing  Compensation.  The  Servicing Fees
payable to PHMC with respect to the Mortgage Loans serviced by PHMC are  subject
to  reduction in any month to  cover Prepayment Interest Shortfalls with respect
to such Mortgage  Loans. The servicing  compensation, including Servicing  Fees,
payable  to any  Other Servicer is  subject to  reduction in any  month to cover
Prepayment Interest Shortfalls and Curtailment Interest Shortfalls with  respect
to  the Mortgage Loans serviced by such Servicer. See "Servicing of the Mortgage
Loans--Fixed Retained Yield, Servicing Compensation and Payment of Expenses"  in
the  Prospectus  for  information  regarding other  possible  compensation  to a
Servicer. No  Fixed  Retained Yield  (as  defined  in the  Prospectus)  will  be
retained with respect to any of the Mortgage Loans. The Master Servicer will pay
all  routine expenses, including fees of the Trustee 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  holders  of  the  Class  A-R  Certificate  and  the  Class   A-LR
Certificate,  respectively, who are individuals, estates or trusts (whether such
Certificate is  held  directly  or through  certain  pass-through  entities)  as
additional  gross income without  a corresponding distribution  of cash, and any
such investor (or  its owners,  in the  case of  a pass-through  entity) may  be
limited  in its ability to deduct such expenses for regular tax purposes and may
not be able to deduct  such expenses to any  extent for alternative minimum  tax
purposes.  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.
 
SERVICER DEFAULTS
 
    The Trustee will  have the  right pursuant  to the  Servicing Agreements  to
terminate a Servicer in certain events, including the breach by such Servicer of
any  of its material obligations under its  Servicing Agreement. In the event of
such termination,  (i)  the  Trustee  may  enter  into  a  substitute  Servicing
Agreement  with the  Master Servicer  or, at  the Master  Servicer's nomination,
another servicing institution acceptable to the Trustee and each Rating  Agency;
and  (ii) the Master  Servicer shall assume certain  of the Servicer's servicing
obligations under such  Servicing Agreement,  including the  obligation to  make
Periodic  Advances (limited  as provided herein  under the  heading "Pooling and
Servicing  Agreement--Periodic  Advances"),  until  such  time  as  a  successor
servicer  is appointed. Any successor Servicer, including the Master Servicer or
the Trustee,  will be  entitled to  compensation arrangements  similar to  those
provided  to the Servicer. See "Servicing  of the Mortgage Loans--Fixed Retained
Yield, Servicing Compensation and Payment of Expenses" in the Prospectus.
 
                       FEDERAL INCOME TAX CONSIDERATIONS
 
    The following discussion represents the opinion of Cadwalader, Wickersham  &
Taft  as  to the  anticipated material  federal income  tax consequences  of the
purchase, ownership and disposition of the Offered Certificates.
 
    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 Master Servicer in  a separate account in which collections
on the  Mortgage  Loans  will  be  deposited  (the  "Master  Servicer  Custodial
Account"),   the  hazard  insurance  policies  and  primary  mortgage  insurance
policies, if any, relating to the Mortgage Loans and any property that secured a
Mortgage Loan that 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) and all Subclasses
of the Class B Certificates. The Class A-1, Class A-2, Class A-3, Class A-5  and
Class A-6 Certificates (collectively, the "Regular Certificates"), together with
the  Class A-4 TAC A Component, the Class A-4 TAC B Component, the Class A-4 TAC
Accrual Component, the Class A-4 IO A
 
                                      S-79
<PAGE>
Component, the Class  A-4 IO B  Component, the  Class A-4 PO  Component and  the
Class   B-1,  Class  B-2,  Class  B-3,  Class  B-4,  Class  B-5  and  Class  B-6
Certificates, will be designated as  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.
 
    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 and  Class A-5  Certificates will be
issued with original issue discount  in an amount equal  to the excess of  their
initial  principal balances (plus four days of interest at the Pass-Through Rate
thereon) over their respective issue prices (including accrued interest). It  is
also anticipated that the Class A-2 and Class A-3 Certificates will be issued at
a  premium and that  the Class A-6  Certificates will be  issued with DE MINIMIS
original  issue  discount  for  federal  income  tax  purposes.  It  is  further
anticipated  that the  Class A-4,  Class B-1, Class  B-2, Class  B-3, Class B-4,
Class B-5 and  Class B-6  Certificates, which are  not offered  hereby, will  be
issued with original issue discount for federal income tax purposes.
 
    The  Prepayment Assumption  (as defined in  the Prospectus)  that the Master
Servicer intends to  use in determining  the rate of  accrual of original  issue
discount  will be calculated using 250% 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  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  AND CLASS A-LR CERTIFICATEHOLDERS'
REMIC TAXABLE  INCOME  AND  THE  TAX  LIABILITY  THEREON  MAY  EXCEED,  AND  MAY
SUBSTANTIALLY 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  holder 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 holders 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, the Class  A-R Certificate will,  and the  Class
A-LR  Certificate may, be considered a "noneconomic residual interest," 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
transfer  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
 
                                      S-80
<PAGE>
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
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 Trust Administrator 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. Additionally, the Class A-R and
Class A-LR Certificates generally may not be transferred to certain persons  who
are   not  U.S.   Persons  (as   defined  herein).   See  "Description   of  the
Certificates--Restrictions  on  Transfer  of  the  Class  A-R  and  Class   A-LR
Certificates"  herein  and  "Certain  Federal  Income  Tax Consequences--Federal
Income Tax  Consequences  For  REMIC Certificates,"  "--  Taxation  of  Residual
Certificates--Limitations   on  Offset   or  Exemption  of   REMIC  Income"  and
"--Tax-Related Restrictions  on Transfer  of Residual  Certificates--Noneconomic
Residual Interests" in the Prospectus.
 
    An  individual,  trust or  estate that  holds  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 applicable REMIC  in computing such holder's  regular tax liability, and
may not be able to deduct such fees or expenses to any extent in computing  such
holder's  alternative  minimum tax  liability. In  addition,  some portion  of a
purchaser's basis, 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 the 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, OR MAY BE NEGATIVE.
 
    See "Certain Federal Income Tax Consequences" in the Prospectus.
 
                              ERISA CONSIDERATIONS
 
    Neither  the  Class A-R  Certificate or  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 (an
"ERISA Plan") or which is  a governmental plan, as  defined in Section 3(32)  of
ERISA, subject to any federal, state or local law ("Similar Law") which is, to a
material  extent,  similar to  the  foregoing provisions  of  ERISA or  the Code
(collectively, with an ERISA Plan, a "Plan"), or any person utilizing the assets
of such Plan. Accordingly, the following discussion does not purport to  discuss
the considerations under ERISA, Code Section 4975 or Similar Law with respect to
the  purchase, acquisition or resale of the  Class A-R or Class A-LR Certificate
and for  purposes of  the following  discussion all  references to  the  Offered
Certificates are deemed to exclude the Class A-R and Class A-LR 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 an ERISA  Plan. Comparable duties and restrictions may
exist under Similar Law on governmental plans and on certain persons who perform
services for governmental plans. For example, unless exempted, investment by  an
ERISA  Plan in the Offered 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  Offered  Certificates,  including  the
individual administrative exemption described  below and Prohibited  Transaction
Class  Exemption 83-1 ("PTE  83-1"). For a further  discussion of the individual
administrative exemption and  PTE 83-1,  including the  necessary conditions  to
their  applicability, and other  important factors to be  considered by an ERISA
Plan  contemplating   investing  in   the  Offered   Certificates,  see   "ERISA
Considerations" in the Prospectus.
 
    On  February  22, 1991,  the  DOL issued  to  the Underwriter  an individual
administrative exemption, Prohibited Transaction  Exemption 91-14, 56 Fed.  Reg.
7413   (the   "Exemption"),   from  certain   of   the   prohibited  transaction
 
                                      S-81
<PAGE>
rules of  ERISA  with respect  to  the initial  purchase,  the holding  and  the
subsequent  resale by an ERISA Plan  of certificates in pass-through trusts that
meet the conditions and requirements of the Exemption. The Exemption might apply
to the acquisition, holding and resale  of the Offered Certificates, other  than
the  Class A-R  and Class  A-LR 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 and a fiduciary of
a governmental plan should  make its own  determination as to  the need for  and
availability  of any  exemptive relief  under Similar  Law. 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, the Code and Similar Law to
such investment. See "ERISA Considerations" in the Prospectus.
 
                                LEGAL INVESTMENT
 
    The Offered 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  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
Offered  Certificates may  be deemed to  be unsuitable investments  under one or
more of these rules, policies and guidelines and certain restrictions may  apply
to  investments in other  Subclasses of Offered 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.  The
appropriate  characterization of  the Offered  Certificates under  various legal
investment restrictions,  and thus  the ability  of investors  subject to  these
restrictions  to purchase  Offered Certificates,  may be  subject to significant
interpretive uncertainties.  Investors  should  consult  with  their  own  legal
advisors  in determining  whether and  to what  extent the  Offered Certificates
constitute legal investments for such investors.
 
                                SECONDARY MARKET
 
    There will  not be  any market  for the  Offered Certificates  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. As  a source  of
information  concerning  the Certificates  and  the Mortgage  Loans, prospective
investors in Certificates may obtain copies  of the reports included in  monthly
statements    to    Certificateholders   described    under    "Description   of
Certificates--Reports" upon  written request  to the  Trustee at  the  Corporate
Trust Office.
 
                                  UNDERWRITING
 
    Subject  to the terms and conditions  of the underwriting agreement dated as
of March  21,  1996  (the  "Underwriting Agreement")  among  the  Seller,  PHMC,
Prudential   Insurance   and   Lehman  Brothers   Inc.,   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
 
                                      S-82
<PAGE>
are  purchased. The Underwriter has advised the Seller that it proposes to offer
the Offered  Certificates, from  time  to time,  in negotiated  transactions  or
otherwise  at prices determined at the time of sale. Proceeds to the Seller from
the sale of the Offered Certificates are expected to be approximately 98.04%  of
the  aggregate  initial  principal  balance of  the  Offered  Certificates, plus
accrued interest thereon  from April 1,  1996 to (but  not including) April  29,
1996, 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 for the Offered Certificates
among the Offered Certificates. The Underwriter, the Dealer 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,  PHMC and  Prudential
Insurance will indemnify the Underwriter against certain civil liabilities under
the  Securities  Act or  contribute  to payments  which  the Underwriter  may be
required to make in respect thereof.
 
                                 LEGAL MATTERS
 
    The validity  of  the Offered  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 Offered Certificates
will be applied by the  Seller to the purchase from  PHMC of the Mortgage  Loans
underlying the Series 1996-6 Certificates.
 
                                    RATINGS
 
    It  is a  condition to  the issuance of  the Offered  Certificates that each
Subclass will have been rated "AAA" by Fitch and "AAA" 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 Fitch  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. Fitch's
rating opinions address  the structural  and legal aspects  associated with  the
certificates,  including the  nature of  the underlying  mortgage loans. Fitch's
ratings on  pass-through certificates  do not  represent any  assessment of  the
likelihood  or rate of principal prepayments and consequently any adverse effect
the timing of such prepayments could have on an investor's anticipated yield.
 
    S&P's ratings on mortgage  pass-through certificates address the  likelihood
of  receipt by  certificateholders of timely  payments of  interest and ultimate
return of principal. S&P's ratings take into consideration the credit quality of
the mortgage pool including any  credit support providers, structural and  legal
aspects  associated with the  certificates, and the extent  to which the payment
stream of the  mortgage pool  is adequate to  make 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 Seller has  not requested a  rating on the  Offered Certificates of  any
Subclass  by any  rating agency  other than  Fitch 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 if a rating is
assigned to any Subclass of Offered Certificates by any other rating agency such
rating will be as high as those assigned by Fitch and S&P.

THE PRUDENTIAL HOME MORTGAGE SECURITIES COMPANY, INC.                     [LOGO]
                                     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 either to
PHMC's underwriting  standards,  to  the  extent  specified  in  the  applicable
prospectus  supplement,  to the  underwriting standards  of  a Pool  Insurer (as
defined herein) or to  such other standards as  are described in the  applicable
Prospectus  Supplement. Unless otherwise specified  in the applicable prospectus
supplement, all of  the Mortgage Loans  will be serviced  either solely by  PHMC
(which in such capacity is referred to herein as the "Sole Servicer") or by PHMC
together  with one or more other servicers (each, a "Servicer") specified in the
Prospectus  Supplement  who  will  be  supervised  by  an  affiliate  of  PHMSC,
Securitized  Asset  Services Corporation  ("SASCOR," and  in such  capacity, the
"Master 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 Sole  Servicer  or SASCOR's  obligations  as Master
Servicer, neither the  Seller, the  Sole Servicer  or Master  Servicer, nor  any
affiliate  of the Seller or the Sole  Servicer or Master Servicer, will have any
obligations with respect to the Certificates.
 
    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.
                           --------------------------

                         be offered only in fully-registered form.
  A.  Standard

                         fractional undivided beneficial interest in the related

                         holder  thereof to interest payments on the outstanding
                         Stated Amount thereof  at a  fixed rate  (which may  be

                         specified in, the applicable Prospectus Supplement, and
                         distributions  in  reduction  of  such  Stated   Amount
                         determined  in the  manner and applied  in the priority
                         set forth in the applicable Prospectus Supplement.  The
                         aggregate  Stated  Amount  of a  Series  of Multi-Class
                         Certificates may be less  than the aggregate  principal
                         balance of the related Mortgage Loans.

                         with  the  month  following  the  month  in  which  the
                         applicable  Cut-Off Date occurs  (each, a "Distribution
                         Date"). Distributions on Multi-Class Certificates  will
                         be  made monthly,  quarterly, or  semi-annually, on the
                         dates   specified   in   the   applicable    Prospectus
                         Supplement.

                         Certificateholders  of record at  the close of business
                         on  (unless  a  different  date  is  specified  in  the
                         applicable Prospectus Supplement) the last business day
                         of   the  month  preceding  the  month  in  which  such

                         ble  pass-through rate for each Class and Subclass (the
                         "Pass-Through Rate"), as  set forth  in the  applicable
                         Prospectus Supplement, will be passed

                         through  monthly to holders thereof, in accordance with
                         the particular terms of each such Certificate.  Holders
                         of  Multi-Class Certificates will receive distributions
                         of interest on the  Stated Amount of such  Certificate,
                         without regard to the Net Mortgage Interest Rate on the
                         underlying  Mortgage Loans.  The Net  Mortgage Interest
                         Rate for  each Mortgage  Loan in  a given  period  will
                         equal the mortgage interest rate for such Mortgage Loan
                         in  such period,  as specified in  the related mortgage
                         note (the "Mortgage Interest Rate"), less the  retained
                         yield,  if any  (the "Fixed Retained  Yield"), and less
                         amounts reserved for  servicing the  Mortgage Loan  and
                         administration  of the related Trust Estate and related
                         expenses (the  "Servicing  Fee" and  "Master  Servicing
                         Fee," as applicable).
Principal (Including
  Prepayments).........  With  respect to  a Series of  Standard Certificates or
                         Stripped Certificates,  unless otherwise  specified  in
                         the   applicable   Prospectus   Supplement,   principal
                         payments (including  prepayments  in full  and  partial
                         prepayments  received by  a Servicer  (other than PHMC)
                         during  the   month  preceding   the  month   of   such
                         Distribution   Date,   or   by   PHMC   prior   to  the
                         Determination Date  preceding such  Distribution  Date)
                         will  be passed through to holders on such Distribution
                         Date.
Distributions in
  Reduction of Stated
  Amount...............  With respect to a  Series of Multi-Class  Certificates,
                         distributions  in  reduction of  Stated Amount  will be
                         made on each Distribution Date  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.   See   "Description   of   the    Certifi-
                         cates--Distributions to Multi-Class
                         Certificateholders."
Credit Enhancement.....  A  Series  of  Certificates  may  include  one  or more
                         Classes of Senior Certificates and one or more  Classes
                         of Subordinated Certificates. The rights of the holders
                         of  Subordinated  Certificates of  a Series  to receive
                         distributions with  respect  to  the  related  Mortgage
                         Loans  will  be  subordinated  to  such  rights  of the
                         holders of the Senior  Certificates of the same  Series
                         to  the extent (the "Subordinated Amount") specified in
                         the applicable Prospectus 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  "Subor-
                         dination  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  Subordi-
                         nated    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,  the  protection  afforded  to  holders  of
                         Senior Certificates of a Series by the subordination of
                         certain  rights of holders of Subordinated Certificates
                         of such Series to distributions on the related Mortgage
                         Loans 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 related Trust Estate.
                         See "Description of the Certificates--Distributions  to
                         Percentage Certificateholders--Shifting Interest
                         Certificates."
                         The  Certificates  of any  Series, or  any one  or more
                         Classes thereof, may be entitled  to the benefits of  a
                         guarantee,  letter of  credit, mortgage  pool insurance
                         policy or other form of credit enhancement as specified
                         in   the   applicable   Prospectus   Supplement.    See
                         "Description of the Certificates" and "Credit Support."
Periodic Advances......  In  the  event  of  delinquencies  in  payments  on any
                         Mortgage Loan,  the  Servicer servicing  such  Mortgage
                         Loan  will make advances  of cash ("Periodic Advances")
                         to the Custodial Account (as defined herein) or, if the
                         Sole Servicer, to the  Certificate Account (as  defined
                         herein)  to the extent  that such Servicer  or the Sole
                         Servicer determines  such  Periodic Advances  would  be
                         recoverable  from  future payments  and  collections on
                         such Mortgage Loan. Any such Periodic Advances will  be
                         reimbursable  to such Servicer or  the Sole Servicer as
                         described  herein  and  in  the  applicable  Prospectus
                         Supplement.  In cases involving  more than one Servicer
                         and  to  the   extent  described   in  the   Prospectus
                         Supplement,  the Master Servicer or the Trustee may, in
                         certain circumstances,  be  required to  make  Periodic
                         Advances upon a Servicer default. See "Servicing of the
                         Mortgage   Loans--Periodic  Advances   and  Limitations
                         Thereon."
Optional Purchase of
  Mortgage
  Loans................  The Seller,  the  Sole  Servicer, or  with  respect  to
                         Series  having a Master  Servicer, the Master Servicer,
                         may subject to the terms of the applicable Pooling  and
                         Servicing  Agreement  purchase  any  defaulted Mortgage
                         Loan from  the related  Trust  Estate. See  "The  Trust
                         Estates--Mortgage  Loans-- Optional Repurchases." If so
                         specified in the Prospectus Supplement with respect  to
                         a  Series, all, but not less  than all, of the Mortgage
                         Loans in  the related  Trust  Estate and  any  property
                         acquired  in  respect  thereof  at  the  time,  may  be
                         purchased by the  person or persons  specified in  such
                         Prospectus  Supplement in  the manner and  at the price
                         specified in such Prospectus  Supplement. In the  event
                         that  an election  is made  to treat  the related Trust
                         Estate (or a  segregated pool of  assets therein) as  a
                         REMIC, any such purchase will be effected only pursuant
                         to  a "qualified liquidation," as defined under Section
                         860F(a)(4)(A) of the Internal Revenue Code of 1986,  as

                         amended (the "Code"). Exercise of the right of purchase
                         will effect the early retirement of the Certificates of
                         that Series. See "Prepayment and Yield Considerations."
ERISA Limitations......  A fiduciary of any employee benefit plan subject to the
                         fiduciary  responsibility  provisions  of  the Employee
                         Retirement Income  Security  Act of  1974,  as  amended
                         ("ERISA"), including the "prohibited transaction" rules
                         thereunder,  and to the corresponding provisions of the
                         Code,  should  carefully  review  with  its  own  legal
                         advisors   whether   the   purchase   or   holding   of
                         Certificates  could   give   rise  to   a   transaction
                         prohibited  or otherwise  impermissible under  ERISA or
                         the Code. See "ERISA Considerations."
Tax Status.............  The treatment of  the Certificates  for federal  income
                         tax  purposes will be determined (i) by whether a REMIC
                         election  is  made   with  respect  to   a  Series   of
                         Certificates  and,  if  a REMIC  election  is  made, by
                         whether  the  Certificates  are  Regular  Interests  or
                         Residual  Interests  and (ii)  by  whether, if  a REMIC
                         election is not made,  the Certificates of such  Series
                         are Standard Certificates or Stripped Certificates. See
                         "Certain Federal Income Tax Consequences."
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
                         rating categories by at least one nationally recognized
                         statistical rating  organization (a  "Rating  Agency").
                         Standard  Certificates  may or  may not  be rated  by a
                         Rating Agency.

                    RISK FACTORS AND SPECIAL CONSIDERATIONS
 
    Investors  should  consider, among  other things,  the following  factors in
connection with the purchase of Offered Certificates.
 
LIMITED LIQUIDITY
 
    There can be no  assurance that a secondary  market for the Certificates  of
any  Series  will  develop  or,  if  it  does  develop,  that  it  will  provide
Certificateholders with liquidity of investment or that it will continue for the
life of the Certificates of any Series. The Prospectus Supplement for any Series
of Certificates may indicate  that an underwriter  specified therein intends  to
establish  a secondary market in such  Certificates, however no underwriter will
be obligated to do  so. The Certificates  will not be  listed on any  securities
exchange.
 
LIMITED OBLIGATIONS
 
    Except  for any  related insurance policies  and any reserve  fund or credit
enhancement described in  the applicable Prospectus  Supplement, Mortgage  Loans
included  in the related Trust Estate will be the sole source of payments on the
Certificates of a Series. The Certificates  of any Series will not represent  an
interest  in or obligation of  PHMSC, PHMC, SASCOR, the  Trustee or any of their
affiliates, except  for  PHMSC's limited  obligations  with respect  to  certain
breaches  of its representations  and warranties and  PHMC's obligations as Sole
Servicer or SASCOR's obligations as Master Servicer. Neither the Certificates of
any Series nor the related Mortgage Loans  will be guaranteed or insured by  any
governmental agency or instrumentality, PHMSC, PHMC, SASCOR, the Trustee, any of
their  affiliates or any other person.  Consequently, in the event that payments
on the Mortgage  Loans are  insufficient or  otherwise unavailable  to make  all
payments required on the Certificates, there will be no recourse to PHMSC, PHMC,
SASCOR,  the  Trustee  or,  except as  specified  in  the  applicable Prospectus
Supplement, any other entity.
 
LIMITATIONS, REDUCTION AND SUBSTITUTION OF CREDIT ENHANCEMENT
 
    With respect  to each  Series  of Certificates,  credit enhancement  may  be
provided  in limited amounts to cover certain  types of losses on the underlying
Mortgage Loans. Credit enhancement will be provided in one or more of the  forms
referred  to  herein,  including, but  not  limited to:  subordination  of other
Classes of Certificates  of the same  Series; a limited  guarantee; a letter  of
credit;  a pool insurance policy; a special hazard insurance policy; a mortgagor
bankruptcy bond;  a  reserve fund;  and  any combination  thereof.  See  "Credit
Support"  herein. Regardless  of the  form of  credit enhancement  provided, the
amount of coverage will be limited in  amount and in most cases will be  subject
to  periodic reduction  in accordance with  a schedule  or formula. Furthermore,
such credit enhancements may  provide only very limited  coverage as to  certain
types  of  losses, and  may provide  no coverage  as to  certain other  types of
losses.  All  or  a  portion  of  the  credit  enhancement  for  any  Series  of
Certificates   will  generally  be  permitted   to  be  reduced,  terminated  or
substituted for,  if  each applicable  rating  agency indicates  that  the  then
current rating thereof will not be adversely affected. See "Credit Support."
 
RISKS OF THE MORTGAGE LOANS
 
    An  investment  in  securities  such  as  the  Certificates  which generally
represent interests in mortgage loans may be affected by, among other things,  a
decline  in  real  estate  values  and  changes  in  the  mortgagor's  financial
condition. No assurance can be given that the values of the Mortgaged Properties
(as defined  herein)  securing  the  Mortgage Loans  underlying  any  Series  of
Certificates  have  remained or  will remain  at  their levels  on the  dates of
origination of the related Mortgage Loans. If the residential real estate market
should  experience  an  overall  decline  in  property  values  such  that   the
outstanding balances of the Mortgage Loans comprising a particular Trust Estate,
and  any secondary  financing on  the Mortgaged  Properties, become  equal to or
greater than  the  value  of  the Mortgaged  Properties,  the  actual  rates  of
delinquencies,  foreclosures and losses could be higher than those now generally
experienced in the mortgage lending industry and those experienced in PHMC's  or
other  Servicers' servicing portfolios. In addition, adverse economic conditions
generally, in particular geographic areas or industries, or affecting particular
segments of the borrowing  community (such as  mortgagors relying on  commission
income  and self-employed  mortgagors) and  other factors  which may  or may not
affect real property values, including the purposes for which the Mortgage Loans
were made  and the  uses of  the  Mortgaged Properties,  may affect  the  timely
payment  by mortgagors  of scheduled payments  of principal and  interest on the
Mortgage Loans and, accordingly, the actual rates of delinquencies, foreclosures
and  losses  with  respect  to  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
applicable  credit enhancement, holders of Certificates of the Series evidencing
interests  in  the   related  Trust   Estate  will   bear  all   risk  of   loss
 
                                       12
<PAGE>
resulting  from default  by mortgagors  and will have  to look  primarily to the
value of the Mortgaged Properties for recovery of the outstanding principal  and
unpaid  interest on the defaulted Mortgage  Loans. In addition to the foregoing,
certain geographic  regions  of  the  United  States  from  time  to  time  will
experience   weaker  regional  economic  conditions  and  housing  markets  and,
consequently, will experience higher rates  of loss and delinquency on  mortgage
loans  generally. The Mortgage  Loans underlying certain  Series of Certificates
may be concentrated in  these regions, and such  concentration may present  risk
considerations   in   addition   to   those   generally   present   for  similar
mortgage-backed  securities   without  such   concentration.  See   "The   Trust
Estates--Mortgage Loans" and "PHMC--Mortgage Loan Underwriting."
 
YIELD AND PREPAYMENT CONSIDERATIONS
 
    The  yield of  the Certificates of  each Series  will depend on  the rate of
principal payment  (including  prepayments,  liquidations due  to  defaults  and
repurchases)  on the  Mortgage Loans and  the price  paid by Certificateholders.
Such yield may be adversely affected by a higher or lower than anticipated  rate
of  prepayments on  the related  Mortgage Loans.  In addition,  unless otherwise
specified in the related  Prospectus Supplement, the yield  to investors may  be
adversely affected by shortfalls which may result from the timing of the receipt
of  partial prepayments  or liquidations  as well  as shortfalls  not covered by
aggregate Servicing Fees  related to  a particular Distribution  Date and  which
shortfalls  result from the timing of the receipt of full prepayments. The yield
on Certificates  entitling  the  holders thereof  primarily  or  exclusively  to
payments  of interest on the  Mortgage Loans will be  extremely sensitive to the
rate of prepayments  on the related  Mortgage Loans. In  addition, the yield  on
certain  other types of Classes of Certificates may be relatively more sensitive
to the rate of prepayment  of the related Mortgage  Loans than other Classes  of
Certificates.  Prepayments  are influenced  by  a number  of  factors, including
prevailing  mortgage  market  interest   rates,  local  and  national   economic
conditions and homeowner mobility. See "Prepayment and Yield Considerations."

                               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. The Mortgage Loans will have been originated by PHMC for it own account or
will  have  been acquired  by PHMC  from other  mortgage loan  originators. Each
Mortgage Loan will  have been underwritten  either to PHMC's  standards, to  the
extent  specified in the applicable Prospectus Supplement, to the standards of a
Pool Insurer or to such other  standards set forth in the applicable  Prospectus
Supplement.  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 and  (ii)  purchased  by PHMC  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 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.
 
                                       14
<PAGE>
    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  Sole
Servicer  and  the  Underlying  Servicing Agreements  require  the  Servicers 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.  For  purposes of  this  Prospectus, with  respect  to any
discussion relating to the servicing of Mortgage Loans by a Servicer  (including
PHMC) under an Underlying Servicing Agreement or PHMC as the Sole Servicer under
a  Pooling and Servicing Agreement, each of such Underlying Servicing Agreements
and Pooling and Servicing Agreements are referred to as a "Servicing  Agreement"
and  any Servicer (including PHMC as  Sole Servicer) under a Servicing Agreement
is referred to herein as the "Applicable Servicer."
 
    Unless otherwise  specified  in  the applicable  Prospectus  Supplement,  no
Mortgage  Loan will have had  at origination a Loan-to-Value  Ratio in excess of
95%. 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.  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. 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  or other  Servicers' servicing  portfolios. In  addition,
adverse  economic  conditions  generally,  in  particular  geographic  areas  or
industries, or affecting particular segments of the borrowing community (such as
mortgagors relying on commission income and self-employed mortgagors) and  other
factors which may or may not affect real property values, including the purposes
for which the Mortgage Loans were made and the uses of the Mortgaged Properties,
may  affect the timely payment by  mortgagors of scheduled payments of principal
and interest  on  the Mortgage  Loans  and,  accordingly, the  actual  rates  of
delinquencies,  foreclosures and  losses with respect  to 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.
 
                                       15
<PAGE>
    Unless  otherwise  provided  in the  applicable  Prospectus  Supplement, all
Mortgage Loans will  be covered by  an appropriate standard  form American  Land
Title  Association ("ALTA") title  insurance policy, or  a substantially similar
policy or  form  of  insurance  acceptable  to  the  Federal  National  Mortgage
Association ("FNMA") or the Federal Home Loan Mortgage Corporation ("FHLMC").
 
    If  so specified in the applicable Prospectus Supplement, a Trust Estate may
contain  Mortgage  Loans  subject  to  temporary  interest  subsidy   agreements
("Subsidy  Loans") pursuant  to which the  monthly payments made  by the related
mortgagors will be  less than the  scheduled monthly payments  on such  Mortgage
Loans  with the present  value of the resulting  difference in payment ("Subsidy
Payments") being provided  by the  employer of  the mortgagor,  generally on  an
annual   basis.  Unless   otherwise  specified  in   the  applicable  Prospectus
Supplement, Subsidy Payments  will be  placed in a  custodial account  ("Subsidy
Account")  by  the  Servicer. Despite  the  existence  of a  subsidy  program, a
mortgagor remains  primarily  liable for  making  all scheduled  payments  on  a
Subsidy  Loan and for all other obligations provided for in the related Mortgage
Note and Mortgage Loan.
 
    Subsidy Loans are offered by employers generally through either a  graduated
or  fixed  subsidy loan  program, or  a  combination thereof.  The terms  of the
subsidy agreements relating  to Subsidy Loans  generally range from  one to  ten
years.  The subsidy agreements relating to  Subsidy Loans made under a graduated
program generally will  provide for  subsidy payments that  result in  effective
subsidized  interest rates between  three percentage points  and five percentage
points below  the Mortgage  Interest  Rates specified  in the  related  Mortgage
Notes.  Generally, under a graduated program, the subsidized rate for a Mortgage
Loan will increase approximately one percentage  point per year until it  equals
the full Mortgage Interest Rate. For example, if the initial subsidized interest
rate is five percentage points below the Mortgage Interest Rate in year one, the
subsidized  rate  will increase  to four  percentage  points below  the Mortgage
Interest Rate in year two, and likewise until year six, when the subsidized rate
will equal the Mortgage Interest Rate. Where the subsidy agreements relating  to
Subsidy  Loans are in effect for longer than five years, the subsidized interest
rates generally increase  at smaller  percentage increments for  each year.  The
subsidy  agreements  relating  to  Subsidy  Loans  made  under  a  fixed program
generally will  provide  for  subsidized interest  rates  at  fixed  percentages
(generally  one percentage  point to two  percentage points)  below the Mortgage
Interest Rates for  specified periods,  generally not  in excess  of ten  years.
Subsidy Loans are also offered pursuant to combination fixed/graduated programs.
The subsidy agreements relating to such Subsidy Loans generally will provide for
an  initial fixed  subsidy of  up to  five percentage  points below  the related
Mortgage Interest Rate for up  to five years, and  then a periodic reduction  in
the  subsidy for up to  five years, at an equal  fixed percentage per year until
the subsidized rate equals the Mortgage Interest Rate.
 
    Generally, employers may terminate subsidy programs in the event of (i)  the
mortgagor's  death, retirement,  resignation or termination  of employment, (ii)
the full prepayment  of the Subsidy  Loan by  the mortgagor, (iii)  the sale  or
transfer by the mortgagor of the related Mortgaged Property as a result of which
the  mortgagee  is  entitled to  accelerate  the  Subsidy Loan  pursuant  to the
"due-on-sale" clause  contained in  the Mortgage,  or (iv)  the commencement  of
foreclosure  proceedings or the acceptance of a  deed in lieu of foreclosure. In
addition, some  subsidy programs  provide  that if  prevailing market  rates  of
interest  on mortgage loans similar to a Subsidy Loan are less than the Mortgage
Interest Rate of such Subsidy Loan, the employer may request that the  mortgagor
refinance  such Subsidy Loan and may  terminate the related subsidy agreement if
the mortgagor fails to refinance such  Subsidy Loan. In the event the  mortgagor
refinances  such Subsidy Loan,  the new loan  will not be  included in the Trust
Estate. See "Prepayment and Yield Considerations" herein. In the event a subsidy
agreement is terminated,  the amount remaining  in the Subsidy  Account will  be
returned  to the employer, and the mortgagor  will be obligated to make the full
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
 
                                       16
<PAGE>
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
 
    Any  Servicing Agreement will require the Applicable 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  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 Applicable
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 by the Sole Servicer or the Custodial Account for remittance
to the Master Servicer Custodial Account by a Servicer.
 
    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  Applicable  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 Applicable  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 Servicing Agreement will require the Applicable 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 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
 
                                       17
<PAGE>
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 pursuant  to  an agreement  (the  "PHMC Sale  Agreement").  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
"--Assignment  of  Mortgage Loans  to the  Trustee," and  "--Representations and
Warranties" below.
 
  ASSIGNMENT OF MORTGAGE LOANS TO THE TRUSTEE
 
    At the time of issuance of  each Series of Certificates, the Mortgage  Loans
in  the  related  Trust Estate  will,  pursuant  to the  applicable  Pooling and
Servicing Agreement, be assigned to the Trustee, together with all principal and
interest received on or with respect to such Mortgage Loans after the applicable
Cut-Off Date other than principal and interest due and payable on or before such
Cut-Off Date  and interest  attributable to  the Fixed  Retained Yield  on  such
Mortgage  Loans, if  any. See "Servicing  of the  Mortgage Loans--Fixed Retained
Yield, Servicing Compensation and Payment of Expenses." The Trustee or its agent
will,  concurrently  with   such  assignment,  authenticate   and  deliver   the
Certificates  evidencing such Series to the  Seller in exchange for the Mortgage
Loans. Each  Mortgage Loan  will be  identified in  a schedule  appearing as  an
exhibit  to the applicable  Pooling and Servicing  Agreement. Each such schedule
will include, among other things, the  unpaid principal balance as of the  close
of  business on the applicable Cut-Off Date,  the maturity date and the Mortgage
Interest Rate for each Mortgage Loan in the related Trust Estate.
 
    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.  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,  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
 
                                       18
<PAGE>
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 or Master Servicer Custodial Account, as applicable. 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  or Master  Servicer Custodial  Account, as  applicable, 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
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.
 
    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.

    Buy-Down  Loan or Subsidy  Loan arrangement), for the  payment of any amount
    required by the Mortgage, except for interest accruing from the date of  the
    related Mortgage Note or date of disbursement of the Mortgage Loan proceeds,
    whichever is later, to the date which precedes by 30 days the first Due Date
    under the related Mortgage Note;
 
        (vi)  the Mortgaged Property is undamaged  by water, fire, earthquake or

  OPTIONAL PURCHASES
 
    Subject to the provisions of the applicable Pooling and Servicing Agreement,
the  Seller, the Servicer or the Master  Servicer may, at its option, repurchase

interest thereon and under the conditions set forth in the applicable Prospectus

<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") among the  Seller,
the  Sole Servicer or Master  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  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 Sole Servicer or Master Servicer,
or  the Paying Agent acting  on behalf of the  Sole Servicer or Master 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."

<PAGE>
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
 
    The    discussion   in   this   section   "--Distributions   to   Percentage
Certificateholders" with respect  to the receipt  and distribution of  principal
(including prepayments) and interest focuses on the practices observed currently
by  PHMC,  as Sole  Servicer and,  with  respect to  any Series  of Certificates
involving more than one Servicer, SASCOR as Master Servicer. With respect to any
Series of  Certificates involving  PHMC and  one or  more other  Servicers,  the
following discussion assumes that the other Servicers service the Mortgage Loans
in accordance with PHMC's practices, and the treatment of principal and interest
payments by such other Servicers, to the extent that such treatments differ from
that of PHMC, will be specified in the applicable Prospectus Supplement.
 
  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 Sole Servicer  or Master 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 Sole
Servicer or Master 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
       Applicable 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 ("Curtailments")  and all  prepayments in
       full received by the  Applicable 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;
 
           (b)  (A) 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 Sole Servicer  or Master Servicer, as  the case may be,
       during the  month preceding  the month  in which  such Distribution  Date
 
                                       25
<PAGE>
       occurs, determined as of the date each such Mortgage Loan was repurchased
       or   purchased,  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   (B)   the
       Liquidation  Proceeds (as defined herein) other than Liquidation Proceeds
       which were received prior to the Applicable Servicer's determination that
       no further recoveries on  a defaulted Mortgage  Loan will be  forthcoming
       ("Partial  Liquidation Proceeds") during the month preceding the month in
       which such Distribution Date occurs with respect to each Mortgage Loan in
       respect of which property was acquired, liquidated or foreclosed; and
 
           (c) all  Partial  Liquidation  Proceeds received  by  the  Applicable
       Servicer  on or after  the Determination Date in  the month preceding the
       month  in  which  the   Distribution  Date  occurs   and  prior  to   the
       Determination  Date occurring in the month in which the Distribution Date
       occurs; 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 and after giving effect to any
    partial principal prepayments and Partial Liquidation Proceeds applied as of
    such  Due  Date  and  any  prepayments   in  full  received  prior  to   the
    Determination  Date in the month of  such Due Date (the "Scheduled Principal
    Balance"), whether  or  not  such  interest was  actually  received  by  the
    Applicable  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 prepaid on or after  the Determination Date in the month
    preceding the month in which such Distribution Date occurs 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 of the Applicable Servicer; 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  prepayments  in  full   and
       Curtailments  received  by  the  Applicable  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;
 
           (b) (A) the unpaid principal  balance, less any amounts with  respect
       thereto  constituting Late  Payments attributable to  principal, and less
       any unreimbursed Periodic Advances with respect thereto, of each Mortgage
       Loan which was  repurchased by  the Representing Party  during the  month
       preceding the month in which such
 
                                       26
<PAGE>
       Distribution  Date occurs, determined  as of the  date each such Mortgage
       Loan was  repurchased or  purchased, as  the  case may  be, and  (B)  the
       Liquidation Proceeds (other than Partial Liquidation Proceeds) which were
       received  during the month preceding the month in which such Distribution
       Date occurs  with respect  to  each Mortgage  Loan  in respect  of  which
       property was acquired, liquidated or foreclosed; and
 
           (c)  all  Partial  Liquidation Proceeds  received  by  the Applicable
       Servicer on or after  the Determination Date in  the month preceding  the
       month   in  which  the   Distribution  Date  occurs   and  prior  to  the
       Determination Date occurring in the month in which the Distribution  Date
       occurs; 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 of the Applicable Servicer; 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
Applicable  Servicer after the Cut-Off Date (except  for amounts due on or prior
to the Cut-Off Date), or received by the Applicable 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 Applicable Servicer
or the  Master 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 Applicable Servicer or  the Master Servicer previously has
    made one or more unreimbursed Periodic Advances;
 
        (b) that portion of Liquidation Proceeds with respect to a Mortgage Loan
    which represents any unreimbursed Periodic Advances;
 
        (c) those portions of each payment of interest on a particular  Mortgage
    Loan  which  represent  (i)  the  Fixed Retained  Yield,  if  any,  (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, and (iii)
    with respect to any Series of Certificates involving more than one Servicer,
    the applicable Master Servicing Fee (with respect to such Distribution Date,
    together with the  amounts described in  clause (i), the  "Amounts Held  for
    Future Distribution");
 
        (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  proceeds (including  Liquidation  Proceeds other  than Partial
    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
    principal prepayments in full, Curtailments and Partial Liquidation Proceeds
    received  by  the Applicable  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;
 
                                       27
<PAGE>
        (f)   that portion  of Liquidation Proceeds  which represents any unpaid
    Servicing Fees or any Master Servicing Fee to which the Applicable  Servicer
    or  the  Master Servicer,  respectively, 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 Sole
    Servicer or Master Servicer or any  Servicer and other amounts permitted  to
    be  withdrawn by the  Sole Servicer or Master  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  and  payments  of  interest  related  to principal
    prepayments received on  or after  the first  day of  the month  in which  a
    Distribution Date occurs and prior to the Determination Date in the month of
    such  Distribution Date which the Applicable  Servicer is entitled to retain
    pursuant to the applicable Servicing Agreement;
 
        (j)   reinvestment  earnings on  payments  received in  respect  of  the
    Mortgage Loans; and
 
        (k)  any  recovery  of  an  amount in  respect  of  principal  which had
    previously been allocated as a realized loss to such Series of Certificates.
 
    The Sole  Servicer or  Master 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 distributable to the  Subordinated Certificateholders and the
amounts in  the related  Subordination Reserve  Fund, if  any, except  that  the
 
                                       28
<PAGE>
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 Sole Servicer or Master 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 Sole Servicer or Master 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 of the  Applicable Servicer, 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
    and Partial  Liquidation Proceeds  received by  the Applicable  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)  the Scheduled
    Principal Balance  of each  Mortgage Loan  which (i)  was the  subject of  a
    principal prepayment in full received by the Applicable 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, or (ii) 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 during
    such preceding month; and
 
        (iv)  such Class's specified percentage  of the net Liquidation Proceeds
    (other than net Partial  Liquidation Proceeds) from  any Mortgage Loan  that
    became a liquidated Mortgage Loan during such preceding month;
 
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
 
                                       29
<PAGE>
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
principal prepayments and Partial Liquidation Proceeds applied by the Applicable
Servicer  on  such first  day of  the month  prior  to the  month in  which such
Distribution Date  falls.  Under  its  current  servicing  practices,  principal
prepayments  and Partial Liquidation Proceeds 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,  holders of 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  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 discussion  in this  section "--Example  of Distribution  to  Percentage
Certificateholders"  with respect to  the receipt and  distribution of principal
including prepayments and  interest payments focuses  on the practices  observed
currently  by  PHMC  as  Sole  Servicer  and,  with  respect  to  any  Series of
Certificates involving more than one  Servicer, SASCOR as Master Servicer.  With
respect  to any  Series of  Certificates involving  PHMC and  one or  more other
Servicers, the following discussion assumes that the other Servicers service the
Mortgage Loans  in  accordance with  PHMC's  practices, and  the  treatments  of
principal  prepayments  by  such  other  Servicers,  to  the  extent  that  such
treatments differ  from  that of  PHMC,  will  be specified  in  the  applicable
Prospectus Supplement.
 
    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        The  Applicable  Servicer   receives  any   liquidation
  31(B)................  proceeds  for  liquidated Mortgage  Loans  and interest
                         thereon to date of liquidation.
January 31(C)..........  Record Date.
February 1-February      The Applicable Servicer receives scheduled payments  of
  16(D)................  principal and interest due on February 1.
February 17(E).........  Determination Date.
February 18(F).........  Remittance Date.
February 25(G).........  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 Applicable Servicer to the Seller when received.
 
(B) Liquidation  Proceeds 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 liquidated  or an insurance
    claim with respect  to a Mortgage  Loan is settled,  interest on the  amount
    liquidated  or  received  in  settlement is  collected  only  from  the last
    scheduled Due Date to the date of liquidation or settlement.
 
(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
    principal  prepayments  and  Partial Liquidation  Proceeds  received  by the
    Applicable Servicer  in reduction  of the  unpaid principal  balance of  any
    Mortgage  Loan  prior to  February 17,  will be  deposited in  the Custodial
    Account as received  by the Servicer  or in the  Certificate Account in  the
    case  of the Sole Servicer and  will be distributed to Certificateholders on
    the February 25 Distribution Date. Liquidation proceeds (other than  Partial
    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 principal prepayments and Partial Liquidation Proceeds received
    on or after February  17, will be deposited  in the Certificate Account  but
    will   not  be  distributed   to  Certificateholders  on   the  February  25
    Distribution Date. Instead, such amounts will be credited to the Certificate
    Account for distribution to Certificateholders on the March 25  Distribution
    Date. 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
    Applicable Servicer would make  an additional payment to  Certificateholders
    with  respect to  any Mortgage  Loan that  prepaid in  full on  or after the
    Determination  Date  in  the  month  preceding  the  month  in  which   such
    Distribution  Date occurs 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 the end of the month preceding the month
    in which such Distribution Date occurs.
 
                                         (FOOTNOTES CONTINUED ON FOLLOWING PAGE)
 
                                       31

    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.
 
- --------------------------------------------------------------------------------
(FOOTNOTES CONTINUED FROM PRECEDING PAGE)
 
(E) As of the close  of business on February  17, each Applicable Servicer  will
    determine  the amounts  of Periodic Advances  to be made  by such Applicable
    Servicer in respect of Mortgage Loans serviced thereby and the Sole Servicer
    or the Master Servicer will determine 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,  principal prepayments  and Partial
    Liquidation Proceeds received  by each Applicable  Servicer in reduction  of
    the  unpaid principal balance of any Mortgage  Loan prior to February 17 and
    liquidation proceeds (other than Partial 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 Sole Servicer  or Master 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 Sole Servicer or Master 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 Sole Servicer or Master Servicer will
    calculate the  amounts  payable in  respect  of  any other  form  of  credit
    enhancement.
 
(F) With respect to any Series of Certificates involving more than one Servicer,
    unless  otherwise specified in the Prospectus Supplement, each Servicer will
    be required  to  remit to  the  Master  Servicer Custodial  Account  on  the
    February  18  Remittance  Date  all amounts  on  deposit  in  the respective
    Custodial Account  (other than  Amounts Held  for Future  Distribution).  In
    addition,  if at  any time  the amount on  deposit in  any Custodial Account
    (other than  any Eligible  Custodial Account)  exceeds $100,000  or  another
    amount specified in the Prospectus Supplement, the Servicer will be required
    to  remit such excess amount to the Master Servicer Custodial Account within
    one business day thereafter.
 
(G) Unless otherwise so specified in the related Prospectus Supplement, the Sole
    Servicer or Master 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.

    Unless otherwise specified in the Prospectus Supplement relating to a Series
of  Certificates, the aggregate amount that  will be distributed in reduction of
Stated Amount to holders of Multi-Class  Certificates of a Series then  entitled
thereto on any Distribution Date for such Series will equal, to the extent funds
are  available, the sum  of (i) the  Multi-Class Certificate Distribution Amount
(as defined herein)  and (ii)  if and  to the  extent specified  in the  related
Prospectus Supplement, the applicable percentage of the Spread specified in such
Prospectus Supplement.
 
    Unless  otherwise  specified in  the  applicable Prospectus  Supplement, the
"Multi-Class Certificate  Distribution Amount"  with respect  to a  Distribution
Date  for a Series of Multi-Class Certificates will equal the amount, if any, by
which the Stated Amount  of the Multi-Class Certificates  of such Series  (after
taking  into account the amount of interest to  be added to the Stated Amount of
any Class of Compound Interest Certificates on such Distribution Date and before
giving effect  to  any distributions  in  reduction  of Stated  Amount  on  such
Distribution  Date) exceeds the  Pool Value (as defined  herein) of the Mortgage
Loans included in the Trust Estate for such  Series as of the end of the  period
(a "Due Period") specified in the related Prospectus Supplement. For purposes of
determining  the Multi-Class Certificate  Distribution Amount with  respect to a
Distribution Date for  a Series of  Certificates having one  or more Classes  of
Multi-Class  Certificates, the Pool Value of  the Mortgage Loans included in the
Trust Estate for  such Certificates  will be reduced  to take  into account  all
distributions thereon received by the Trustee during the applicable Due Period.
 
    Unless otherwise specified in the applicable Prospectus Supplement, "Spread"
with  respect to  a Distribution Date  for a Series  of Multi-Class Certificates
will be the excess of (a) the sum of (i) all payments of principal and  interest
received on the related Mortgage Loans (net of the Fixed Retained Yield, if any,
and  the applicable  Master Servicing Fee  and/or 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 Applicable Servicer or  the Master Servicer, and  any amount required to  be
deposited  into  any  reserve  fund  from  funds  allocable  to  the Multi-Class
Certificates in the Certificate Account. Reinvestment income on any reserve fund
will not be included in Spread except to the extent that reinvestment income  is
taken into account in calculating the initial amount required to be deposited in
such reserve fund, if any.
 
  VALUATION OF MORTGAGE LOANS
 
    If   specified  in  the  Prospectus  Supplement  relating  to  a  series  of
Multi-Class Certificates, for purposes of  establishing the principal amount  of
Mortgage  Loans that will  be included in  a Trust Estate  for such Series, each
Mortgage Loan to be included  in such Trust Estate  will be assigned an  initial
"Pool   Value."  Unless   otherwise  specified  in   the  applicable  Prospectus
Supplement, the Pool  Value of  each Mortgage  Loan in  the Trust  Estate for  a
Series  is the Stated  Amount of Multi-Class Certificates  of such Series which,
based upon  certain  assumptions  and  regardless of  any  prepayments  on  such
Mortgage  Loans, can  be supported  by the  scheduled payments  of principal and
interest on  such  Mortgage Loans  (net  of the  Fixed  Retained Yield  on  such
Mortgage  Loans,  if  any,  and the  applicable  Servicing  Fee),  together with
reinvestment earnings thereon, if any, at the Assumed Reinvestment Rate for  the
period  specified in the related Prospectus  Supplement and amounts available to
be withdrawn  (if applicable)  from any  reserve fund  for such  Series, all  as
specified in the applicable Prospectus Supplement. In calculating the Pool Value
of  a Mortgage Loan included  in the Trust Estate,  future distributions on such
Mortgage Loan will be  determined based on scheduled  payments on such  Mortgage
Loan.  Any similar  Mortgage Loans  may be  aggregated into  one or  more groups
(each, a "Pool Value Group"), each of  which will be assigned an aggregate  Pool
Value  calculated  as  if  all  such Mortgage  Loans  in  the  Pool  Value Group
constituted a single  mortgage loan  having the  highest mortgage  rate and  the
longest  maturity of any such mortgage loan for such Pool Value Group. There are
a number of alternative means of determining  the Pool Value of a Mortgage  Loan
or  Pool Value Group,  including determinations based  on the discounted present
value of the remaining scheduled payments of principal and interest thereon  and
determinations based on the relationship between the
 
                                       33
<PAGE>
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  Sole
Servicer  or Master  Servicer. Any such  distributions with respect  to a Series
will be described in  the applicable Prospectus Supplement  and will be on  such
terms  and  conditions as  described therein  and specified  in the  Pooling and
Servicing Agreement for such Series.
 
  LAST SCHEDULED DISTRIBUTION DATE
 
    The "Last  Scheduled  Distribution  Date"  for  each  Class  of  Multi-Class
Certificates  of a Series having  a Stated Amount, to  the extent Last Scheduled
Distribution Dates are specified in the applicable Prospectus Supplement, is the
latest date on  which (based upon  the assumptions set  forth in the  applicable
Prospectus Supplement) the Stated Amount of such Class is expected to be reduced
to  zero. Since the rate of distributions  in reduction of Stated Amount of each
such Class of Multi-Class Certificates will depend upon, among other things, the
rate of payment (including prepayments) of  the principal of the Mortgage  Loans
in  the Trust Estate for such Series,  the actual last Distribution Date for any
such  Class  could   occur  significantly  earlier   than  its  Last   Scheduled
Distribution  Date. To  the extent  of any  delays in  receipt of  any payments,
insurance proceeds or liquidation  proceeds with respect  to the Mortgage  Loans
included  in any  Trust Estate,  the last Distribution  Date for  any such Class
could occur  later  than its  Last  Scheduled  Distribution Date.  The  rate  of
payments  on  the  Mortgage  Loans  in  the  Trust  Estate  for  any  Series  of
Certificates will depend upon  their particular characteristics,  as well as  on
the  prevailing level  of interest  rates from time  to time  and other economic
factors, and no assurance can be given as to the actual prepayment experience of
the Mortgage Loans. See "Prepayment and Yield Considerations" below.

SUBORDINATION
 
  CERTIFICATES OTHER THAN SHIFTING INTEREST CERTIFICATES
 
    If so  specified  in the  Prospectus  Supplement  relating to  a  Series  of
Certificates,  other than a Series of Shifting Interest Certificates, the rights
of the holders of a Class of Subordinated Certificates to receive  distributions
will  be  subordinated  to  the rights  of  the  holders of  a  Class  of Senior
Certificates, to  the  extent  of  the Subordinated  Amount  specified  in  such
Prospectus  Supplement. The  Subordinated Amount  will be  reduced by  an amount
equal to  Aggregate Losses  and will  be further  reduced in  accordance with  a
schedule  described in the applicable  Prospectus Supplement. "Aggregate Losses"
as defined  in the  applicable Pooling  and Servicing  Agreement for  any  given
period  will  equal  the aggregate  amount  of delinquencies,  losses  and other
deficiencies  ("Payment  Deficiencies")  in  the  amounts  due  to  the   Senior
Certificateholders  paid or  borne by  the Subordinated  Certificateholders (but
excluding any payments of Senior  Class Shortfall Accruals or interest  thereon)
during  such period, whether such aggregate amount results by way of withdrawals
from the  Subordination Reserve  Fund (including,  prior to  the time  that  the
Subordinated  Amount  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  Sole Servicer  or Master  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  Sole  Servicer  or Master
Servicer will withhold from the Subordinated Certificateholders and will deposit
in the Subordination Reserve Fund such portion of the principal payments on  the
Mortgage Loans otherwise distributable to the Subordinated Certificateholders as
may be necessary to maintain the Subordination Reserve Fund (without taking into
account  the  amount  of the  Initial  Deposit) at  the  Specified Subordination
Reserve Fund Balance. The Prospectus Supplement  for each Series will set  forth
the  amount of the Specified Subordination  Reserve Fund Balance applicable from
time to  time and  the extent,  if  any, to  which the  Specified  Subordination
Reserve Fund Balance may be reduced.
 
    In  no event  will the  Specified Subordination  Reserve Fund  Balance for a
Series ever be  required to  exceed the Subordinated  Amount. In  the event  the
Subordination Reserve Fund is depleted before the Subordinated Amount is reduced
to  zero, the  Senior Certificateholders  will continue  to have  a preferential
right, to  the extent  specified  in the  applicable Prospectus  Supplement,  to
receive  current  distributions  of  amounts  that  would  otherwise  have  been
distributable to the Subordinated Certificateholders  to the extent of the  then
Subordinated Amount.
 
                                       35
<PAGE>
    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  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.
 
                                       36
<PAGE>
    If   specified  in  the  Prospectus  Supplement  relating  to  a  Series  of
Certificates, the Subordination Reserve Fund may  be funded in any other  manner
acceptable  to the  Rating Agency  and consistent with  an election,  if any, to
treat the Trust Estate (or a segregated pool of assets therein) for such  Series
as a REMIC, as will be more fully described in such Prospectus Supplement.
 
  SHIFTING INTEREST CERTIFICATES
 
    If  specified in  the applicable  Prospectus Supplement,  the rights  of the
holders of  the  Subordinated Certificates  of  a Series  of  Shifting  Interest
Certificates  to receive distributions with respect to the Mortgage Loans in the
related Trust Estate will be subordinated to  such rights of the holders of  the
Senior  Certificates of the same Series to the extent described below, except as
otherwise set  forth  in  such  Prospectus  Supplement.  This  subordination  is
intended  to  enhance the  likelihood of  regular receipt  by holders  of Senior
Certificates of the full amount of  scheduled monthly payments of principal  and
interest due them and to provide limited protection to the holders of the Senior
Certificates against losses due to mortgagor defaults.
 
    The protection afforded to the holders of Senior Certificates of a Series of
Shifting Interest Certificates by the subordination feature described above will
be  effected by the preferential right of  such holders to receive, prior to any
distribution being made in respect  of the related Subordinated Certificates  on
each  Distribution Date, current distributions on  the related Mortgage Loans of
principal and  interest due  them on  each Distribution  Date out  of the  funds
available  for distribution on such date in the related Certificate Account and,
to the extent described below,  by the right of  such holders to receive  future
distributions  on the Mortgage  Loans that would otherwise  have been payable to
the holders of Subordinated Certificates.
 
    Losses realized on liquidated Mortgage Loans (other than certain  liquidated
Mortgage  Loans that are Special Hazard  Mortgage Loans as described below) will
be allocated to the holders of Subordinated Certificates through a reduction  of
the amount of principal payments on the Mortgage Loans to which such holders are
entitled.
 
    On  each Distribution  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, 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."
 
    A Mortgage Loan that  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  is  referred to  as  a  "Special Hazard  Mortgage  Loan".  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, the outstanding
principal balance of each Class of  Senior Certificates will be reduced by  such
Class's  specified percentage of the loss  on each Special Hazard Mortgage Loan.
See   "Description    of   the    Certificates--Distributions   to    Percentage
Certificateholders--Shifting Interest Certificates."
 
    Although  the subordination feature  described above is  intended to enhance
the likelihood of  timely payment of  principal and interest  to the holders  of
Senior  Certificates,  shortfalls  could result  in  certain  circumstances. For
example, a shortfall in  the payment of principal  otherwise due the holders  of
Senior  Certificates could occur if  losses realized on the  Mortgage Loans in a
Trust Estate  were exceptionally  high  and were  concentrated in  a  particular
month.   See  "Description  of  the  Certificates--Distributions  to  Percentage
Certificateholders--Shifting Interest  Certificates" for  a description  of  the
consequences of any shortfall of principal or interest.
 
    The  holders of Subordinated Certificates will not be required to refund any
amounts previously properly distributed to them, regardless of whether there are
sufficient funds on a subsequent Distribution  Date to make a full  distribution
to holders of each Class of Senior Certificates of the same Series.

OTHER CREDIT ENHANCEMENT
 
    In  addition to subordination as discussed  above, credit enhancement may be
provided with respect to  any Series of Certificates  in any other manner  which
may  be described  in the applicable  Prospectus Supplement,  including, but not
limited to,  credit enhancement  through an  alternative form  of  subordination
and/or one or more of the methods described below.
 
  LIMITED GUARANTEE
 
    If  so specified in  the Prospectus Supplement  with respect to  a Series of
Certificates, credit  enhancement may  be  provided in  the  form of  a  limited
guarantee issued by a guarantor named therein.
 
  LETTER OF CREDIT
 
    Alternative  credit support with respect to  a Series of Certificates may be
provided by  the  issuance of  a  letter of  credit  by the  bank  or  financial
institution  specified in  the applicable  Prospectus Supplement.  The coverage,
amount and frequency of any reduction in coverage provided by a letter of credit
issued with  respect to  a  Series of  Certificates will  be  set forth  in  the
Prospectus Supplement relating to such Series.
 
  POOL INSURANCE POLICIES
 
    If  so  specified  in the  Prospectus  Supplement  relating to  a  Series of
Certificates, the Seller will  obtain a pool insurance  policy for the  Mortgage
Loans in the related Trust Estate. The pool insurance policy will cover any loss
(subject  to the  limitations described in  a related  Prospectus Supplement) by
reason of default to the  extent a related Mortgage Loan  is not covered by  any
primary  mortgage insurance policy.  The amount and principal  terms of any such
coverage will be set forth in the Prospectus Supplement.
 
  SPECIAL HAZARD INSURANCE POLICIES
 
    If so specified in the applicable Prospectus Supplement, for each Series  of
Certificates  as to which a  pool insurance policy is  provided, the Seller will
also obtain a special  hazard insurance policy for  the related Trust Estate  in
the amount set forth in such Prospectus Supplement. The special hazard insurance
policy  will, subject to the limitations  described in the applicable Prospectus
Supplement, protect against  loss by  reason of damage  to Mortgaged  Properties
caused  by certain hazards not insured against under the standard form of hazard
insurance policy for the respective states in which the Mortgaged Properties are
located. The amount and principal terms of  any such coverage will be set  forth
in the Prospectus Supplement.
 
  MORTGAGOR BANKRUPTCY BOND
 
    If  so specified in  the applicable Prospectus  Supplement, losses resulting
from a  bankruptcy proceeding  relating to  a mortgagor  affecting the  Mortgage
Loans in a Trust Estate with respect to a Series of Certificates will be covered
under  a mortgagor bankruptcy bond (or any other instrument that will not result
in a downgrading of  the rating of  the Certificates of a  Series by the  Rating
Agency or Rating Agencies that rated such Series). Any mortgagor bankruptcy bond
or  such other  instrument will  provide for coverage  in an  amount meeting the
criteria of the Rating Agency or Rating Agencies rating the Certificates of  the
related  Series,  which  amount will  be  set  forth in  the  related Prospectus
Supplement. The amount  and principal  terms of any  such coverage  will be  set
forth in the Prospectus Supplement.
 
                                       38
<PAGE>
                      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  full or in  part, an  interest
shortfall  may result depending on  the timing of the  receipt of the prepayment
and  the   timing   of   when   those  prepayments   are   passed   through   to
Certificateholders. To partially mitigate this reduction in yield, the Servicing
Agreement  relating to a  Series may provide, unless  otherwise specified in the
applicable Prospectus Supplement, that with respect to any principal  prepayment
in  full on or after the Determination Date  in the month preceding the month in
which the related  Distribution Date occurs  and prior  to the Due  Date in  the
month in which such Distribution Date occurs of any Mortgage Loan underlying the
Certificates  of such  Series, the Sole  Servicer will pay  into the Certificate
Account, or  any  other  Servicer  will  pay  into  the  Custodial  Account  for
remittance  to the  Master Servicer  Custodial 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
such 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
 
                                       39
<PAGE>
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, including  the use of second  or "home equity" mortgage
loans by mortgagors or the  use of the properties  as second or vacation  homes,
servicing  decisions,  enforceability  of due-on-sale  clauses,  mortgage market
interest rates,  mortgage  recording  taxes,  competition  among  mortgage  loan
originators  resulting in reduced refinancing  costs, reduction in documentation
requirements and  willingness to  accept higher  loan-to-value ratios,  and  the
availability  of mortgage funds,  may affect prepayment  experience. In general,
however, if prevailing  interest rates  fall below the  Mortgage Interest  Rates
borne  by 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.  Conversely, if
prevailing interest rates rise  above the Mortgage Interest  Rates borne by  the
Mortgage  Loans, the Mortgage Loans are  likely to experience a lower prepayment
rate than if prevailing rates remain  at or below such Mortgage Interest  Rates.
However,  there can be no assurance that prepayments will rise or fall according
to such changes in  interest rates. It  should be noted  that Certificates of  a
Series  may  evidence an  interest  in a  Trust  Estate with  different Mortgage
Interest Rates. Accordingly, the prepayment experience of such Certificates will
to some extent be a function of the mix of interest rates of the Mortgage Loans.
In addition, the terms  of the Servicing Agreement  will require the  Applicable
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, a  Servicer, including PHMC, may allow the
refinancing of a Mortgage Loan in any Trust Estate serviced by such Servicer  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 a Servicer may,
from time to time, implement programs designed to encourage refinancing  through
such  Servicer, 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. A  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, Sole Servicer or Master Servicer, 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
Mortgage Loans to the Trustee"  and"--Optional Repurchases." In addition, if  so
specified  in the applicable Prospectus Supplement,  the Sole Servicer or Master
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.
 
    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 5325 Spectrum Drive, 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--Mortgage
Loans--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
Private Label Mortgage Services Corporation ("PLMSC"), a wholly owned subsidiary
of Residential  Services Corporation  of America  and an  indirect wholly  owned
subsidiary  of  Prudential Insurance,  which processes  loans for  mortgage loan
originators. PLMSC does  not process  loans for  PHMC but  may process  Mortgage
Loans  acquired by  PHMC from  other originators. 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
 
                                       42
<PAGE>
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 certain  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  or the acquisition of  mortgage loans directly  from
mortgage  brokers, 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  and
prospective   borrowers  (including  borrowers  with  mortgage  loans  currently
serviced by  PHMC  or  borrowers  referred  by  borrowers  with  mortgage  loans
currently  serviced by  PHMC), (ii) mortgage  brokers and  similar entities, and
(iii) other originators.  The first  two categories involve  the origination  of
mortgage  loans by PHMC through either direct  contact with the applicant or 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,
prospective borrowers or mortgage brokers and similar entities typically involve
either  direct contact with the applicant or the referral of a loan applicant to
PHMC; the gathering of credit-related and property-specific information by PHMC;
and the decision by PHMC, based on  its analysis of such information, as to  the
suitability of its making the loan. It is characteristic of PHMC's practice with
respect  to  loans generated  as  a result  of  direct contact  with prospective
borrowers or referrals from these  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 who is directly contacted by PHMC or referred to PHMC by a borrower
with a mortgage loan currently serviced by PHMC or 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
direct  contact with  prospective borrowers  or referrals  generally exceeds the
more limited processing role associated with  loans acquired by PHMC from  other
originators. It is PHMC's
 
                                       43
<PAGE>
general  practice to review  and evaluate 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.
 
    PHMC's  direct contacts with prospective borrowers (including borrowers with
mortgage loans currently serviced by PHMC) are made through general and targeted
solicitations. Such  solicitations are  made through  direct mailings,  mortgage
loan  statement inserts  and television, radio  and print  advertisements and by
telephone. PHMC targeted solicitations may  be based on characteristics such  as
the borrower's mortgage loan interest rate or payment history and the geographic
location  of the mortgaged  property. See "Prepayment  and Yield Considerations"
herein.
 
    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 or the  standards of a Pool  Insurer and represent  that
each loan was underwritten in accordance with PHMC standards or the standards of
a  Pool  Insurer, 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.  The
contractual   arrangements  with  eligible  originators  may  also  involve  the
delegation  of  all  underwriting  functions  to  such  originators  ("Delegated
Underwriting"),  which  will  result  in PHMC  not  performing  any underwriting
functions prior  to  acquisition  of  the  loan  but  instead  relying  on  such
originators'  representations, and PHMC's post-purchase  reviews of samplings of
mortgage  loans  acquired  from  such  originators  regarding  the  originators'
compliance  with  PHMC's  underwriting  standards.  In  all  instances, however,
acceptance by PHMC is  contingent upon the loans  being found to satisfy  PHMC's
program  standards or  the standards  of a Pool  Insurer. PHMC  may also acquire
portfolios of seasoned loans in negotiated transactions.
 
MORTGAGE LOAN UNDERWRITING
 
    PHMC's underwriting  standards  are applied  by  or  on behalf  of  PHMC  to
evaluate  the applicant's credit standing and ability to repay the loan, as well
as the  value  and  adequacy  of  the  mortgaged  property  as  collateral.  The
underwriting  standards that  guide the  determination represent  a balancing of
several factors that may affect the ultimate
 
                                       44
<PAGE>
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. With respect to certain Mortgage Loans, the originators of  such
loans  may  have  contracted  with unaffiliated  third  parties  to  perform the
underwriting process.
 
    In November 1994, PHMC implemented enhanced credit scoring ("ECS") as a tool
to supplement the mortgage  loan underwriting process. ECS  assists PHMC in  the
mortgage  loan approval process  by providing consistent,  objective measures of
borrower credit and  loan attributes.  An "ECS Score"  is a  combination of  two
parts, the first being a credit score and the second being an application score.
The  credit  score assists  in  a determination  of  the credit  quality  of the
borrower. The application score, which incorporates certain loan application and
borrower characteristics (such as Loan-to-Value Ratio and borrower  occupation),
reflects risk attributes specific to the proposed loan and the borrower. The ECS
Score  is used to determine the type  of underwriting process and which level of
underwriter will review the loan file. For transactions which are determined  to
be  low-risk  transactions,  based  upon  the  ECS  Score  and  other parameters
(including  the  mortgage  loan  production  source),  the  lowest  underwriting
authority  is  generally required.  For moderate  and higher  risk transactions,
higher level underwriters and a full  review of the mortgage file are  generally
required.  Borrowers who have a satisfactory  ECS Score (based upon the mortgage
loan production  source)  are subject  generally  to streamlined  credit  review
(which  automates  various elements  of  the underwriting  process)  and limited
documentation  requirements  and  are  permitted  a  greater  latitude  in   the
application of borrower debt-to-income ratios.
 
    With respect to all mortgage loans underwritten by PHMC, 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, 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 or  funding
decision. 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.
 
    The underwriting of mortgage loans acquired by PHMC pursuant to a  Delegated
Underwriting  arrangement  with  another  originator is  not  reviewed  prior to
acquisition of the  mortgage loan  by PHMC although  the mortgage  loan file  is
reviewed  by PHMC to  confirm that certain  documents are included  in the file.
Instead, PHMC relies on (i) the originator's representations that such  mortgage
loan  was underwritten in accordance with PHMC's underwriting standards and (ii)
a post-purchase review of  a sampling of all  mortgage loans acquired from  such
originator.  In addition, in order to be eligible to sell mortgage loans to PHMC
pursuant to  a  Delegated Underwriting  arrangement,  the originator  must  meet
certain requirements including, among other things, certain quality, operational
and financial guidelines.
 
    A  prospective borrower applying for a mortgage loan is required to complete
a detailed application. 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
obtained by or on behalf of PHMC, and that PHMC authorizes parties referring  or
selling   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 exception of the use of contract underwriters and
Delegated  Underwriting arrangements  obtained by or  on behalf  of PHMC, itself
order a  credit report  of  the type  described, whether  or  not a  report  has
previously been ordered with
 
                                       45
<PAGE>
respect  to an applicant  for whom another  party has processed  or approved the
loan. Certain of  the credit reports  obtained by or  on behalf of  PHMC may  be
purchased  through a credit  reporting service with which  LSI has a contractual
relationship. The credit review process  generally is streamlined for  borrowers
with a qualifying ECS Score.
 
    Verifications  of employment,  income, assets  or mortgages  may be  used to
supplement  the  loan  application   and  the  credit   report  in  reaching   a
determination  as  to  the  applicant's  ability  to  meet  his  or  her monthly
obligations on the proposed mortgage loan, as well as his or her other  mortgage
payments  (if  any),  living  expenses  and  financial  obligations.  A mortgage
verification involves  obtaining information  regarding the  borrower's  payment
history  with  respect to  any existing  mortgage the  applicant may  have. This
verification is  accomplished by  either having  the present  lender complete  a
verification  of mortgage form, evaluating the  information on the credit report
concerning  the  applicant's   payment  history  for   the  existing   mortgage,
communicating,  either  verbally or  in  writing, with  the  applicant's present
lender or analyzing cancelled checks provided by the applicant. Verifications of
income, assets or  mortgages may  be waived  under certain  programs offered  by
PHMC, but PHMC's underwriting guidelines require, in most instances, a verbal or
written  verification  of  employment  to be  obtained.  In  addition,  the loan
applicant may  be  eligible  for  a loan  approval  process  permitting  limited
documentation.  The above  referenced reduced documentation  options and 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, the ratio of the loan amount to the
property value and the  mortgage loan production  source. The least  restrictive
reduced-documentation  programs apply to the applicant for a relocation loan and
to  the  borrower  whose  loan  amount  does  not  exceed  $500,000  and   whose
Loan-to-Value Ratio is not in excess of 70%. 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.
 
    In general, all borrowers applying for loans with Loan-to-Value Ratios  less
than or equal to 90%, other than borrowers applying for loans that are not loans
with respect to a principal residence, 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%; all other borrowers 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 generally
the initial mortgage interest rate, which is generally lower than the sum of the
index rate 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 certain compensating  factors are  identified,
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. Borrowers with an ECS Score which qualifies
for streamlined credit review generally may  have a ratio of total monthly  debt
to  monthly gross income significantly in excess  of 38%, and the ratio of total
monthly housing debt to monthly  gross income may not  be considered by PHMC  in
the  underwriting of a loan to such a borrower. 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  housing  debt-to-income ratios  described  above,  and  the
combined  amount of primary  and secondary loans  will be used  to calculate the
combined loan-to-value ratio. Any  secondary financing permitted will  generally
mature  prior to the maturity  date of the related  mortgage loan. In evaluating
 
                                       46
<PAGE>
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  include projected  rental
income  net of certain mortgagor obligations  and other assumed expenses or loss
from such property  to be included  in the applicant's  monthly gross income  or
total  monthly debt in calculating the foregoing ratios. A mortgage loan secured
by  a  two-  to   four-family  Mortgaged  Property  is   considered  to  be   an
owner-occupied property if the borrower occupies one of the units; rental income
on  the other units is generally taken into account in evaluating the borrower's
ability to repay the mortgage loan.
 
    Property value  is established  in connection  with the  origination of  any
mortgage  loan  (whether  the loan  is  originated for  purchase  or refinancing
purposes) by means  of an  appraisal, which is  typically ordered  by the  party
originating  the  related  mortgage  loan. Consistent  with  this  practice, the
appraisals with respect  to the  loans generated through  corporate contacts  or
through  referrals from mortgage  brokers or other  similar entities (other than
those certain mortgage brokers or  similar entities that process mortgage  loans
on  PHMC's  behalf) are  generally ordered  by PHMC,  while the  appraisals with
respect to the  loans sold to  PHMC by third-party  lenders or certain  mortgage
brokers  are  ordered by  those  other originators.  PHMC  may, however,  at its
discretion, order a  review appraisal with  respect to any  loan generated by  a
third-party lender or mortgage broker; 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,
typically 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,  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 some
third-party lenders and mortgage brokers which  sell or refer mortgage loans  to
PHMC.
 
    Many  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   $500,000  that  have  Loan-to-Value  Ratios  exceeding  80%.  Only  primary
residences  (excluding  cooperatives)  are  eligible  for  this  program.   Each
qualifying  loan will be made  at an interest rate that  is higher than the rate
would be if  the Loan-to-Value  Ratio was  80% or  less or  if primary  mortgage
insurance  was  obtained. Loans  that do  not  qualify for  such program  may be
approved if  primary mortgage  insurance is  obtained from  an approved  primary
mortgage  insurance company. In such cases, the  excess over 75% will be covered
by primary mortgage insurance until the unpaid principal balance of the Mortgage
Loan is reduced to an amount that will result in a Loan-to-Value Ratio less than
or equal to 80%.
 
    Where permitted by law, PHMC generally  requires that a borrower include  in
each  monthly payment a  portion of the real  estate taxes, assessments, primary
mortgage insurance  (if applicable),  and hazard  insurance premiums  and  other
 
                                       47
<PAGE>
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.
 
    If  specified  in  the  applicable  Prospectus  Supplement,  certain  of the
Mortgage Loans will have  been reviewed by  General Electric Mortgage  Insurance
Corporation  ("GEMICO"), United Guaranty Residential Insurance Company ("UGRIC")
or a similar entity (collectively, the "Pool Insurers") to determine conformity,
in  the  aggregate,  with  such  company's  respective  credit,  appraisal   and
underwriting  guidelines. PHMC will  not have underwritten  such Mortgage Loans.
Neither GEMICO  nor  UGRIC have  underwritten  any  of the  Mortgage  Loans  for
compliance with any investor guidelines.
 
    Based  on information  provided by the  relevant company, as  a condition to
eligibility of a Mortgage Loan for inclusion in a mortgage pool to be insured by
GEMICO or UGRIC, the loan originator  generally will be required to comply  with
the  following procedures, although exceptions may  be made if permitted by such
company.
 
    Initially, a  prospective  borrower must  fill  out a  detailed  application
providing  pertinent credit  information. The  loan originator  obtains a credit
report,  which  summarizes  the  prospective  borrower's  credit  history   with
merchants  and lenders  and any record  of bankruptcy, or  other pertinent legal
history. In addition,  a verification of  employment for the  last two years  is
made  from either the applicant's employer or a Form W-2 for the most recent two
years  and  the  applicant's   most  recent  pay  stub.   If  an  applicant   is
self-employed,  such applicant  submits copies  of signed  tax returns  with all
schedules for the prior  two years together with  a current year-to-date  profit
and  loss statement and any other  documentation deemed necessary. Rental income
used to qualify the applicant  is verified by lease  agreements. In the case  of
refinancings,  the loan originator must require,  among other things, that there
has not been more than one delinquency in  the prior 12 months nor, in the  case
of mortgage loans reviewed by GEMICO, any delinquency in the past 90 days on the
prior mortgage loan.
 
    In  determining the  adequacy of  the Mortgaged  Property as  collateral, an
independent appraisal must be  made of each  property considered for  financing.
Each  appraiser  must be  selected in  accordance with  predetermined guidelines
established for appraisers. The  appraiser is required  to inspect the  property
and  verify that it is in good condition and that construction, if new, has been
completed. The appraisal is  based on the market  value of comparable homes.  No
appraisal  more than six months old will  be accepted by GEMICO and no appraisal
more than 120 days old will be accepted by UGRIC.
 
    Once all applicable employment, credit and property information is received,
a determination must be made by the loan originator (and confirmed on review  by
GEMICO  or UGRIC) as to whether  the prospective borrower has sufficient monthly
income to meet (i) the monthly payment obligations on the proposed mortgage loan
(including principal and interest payments, real estate taxes, insurance on  the
subject  property, and homeowners' association  dues and secondary financing, if
any),  and  (ii)  the  aggregate  of  the  foregoing  and  all  other  financial
obligations  not expected  to be fully  repaid within  the next 10  months. As a
general rule, GEMICO  and UGRIC require  the ratio of  a prospective  borrower's
debt,  as described in clauses (i) and  (ii) above, to such borrower's income to
be 33% and  38%, respectively for  fixed rate, fixed  payment loans. The  ratios
required  for adjustable rate loans are slightly  lower. The general rule may be
varied, and higher debt-to-income ratios may be permitted, in appropriate  cases
characterized by lower Loan-to-Value Ratios or other favorable factors.
 
    In  some  special  cases, GEMICO  and  UGRIC  may underwrite  loans  under a
"limited  documentation"   program.  With   respect  to   such  loans,   limited
investigation   into  the  borrower's  credit  history  and  income  profile  is
undertaken by the originator and such loans may be underwritten primarily on the
basis of  an appraisal  of the  mortgaged property  and Loan-to-Value  Ratio  on
origination.  Thus,  if  the Loan-to-Value  Ratio  is less  than  the percentage
required under standard guidelines, the originator may forego certain aspects of
the review  relating to  monthly income,  and,  in the  case of  mortgage  loans
reviewed  by GEMICO,  traditional ratios of  monthly or total  expenses to gross
income may not be  applied. At a minimum,  a limited documentation program  must
require  a  loan  application,  a  credit  report,  an  appraisal  acceptable to
FNMA/FHLMC  performed  by  an  independent  appraiser,  and  a  verification  of
downpayment  or three months of bank statements. The maximum Loan-to-Value Ratio
allowed under any limited documentation program underwritten by GEMICO and UGRIC
is 70%. UGRIC's "limited documentation" program is limited exclusively to  self-
employed borrowers.
 
                                       48
<PAGE>
    For  any rate  or term  refinance of  a mortgage  loan, or  conversion of an
adjustable rate mortgage  loan, where GEMICO  or UGRIC has  already insured  the
prior  loan, GEMICO or  UGRIC may have determined  a loan's insurability without
reviewing updated  credit or  collateral information.  In the  case of  seasoned
loans, GEMICO or UGRIC may have determined a loan's insurability by performing a
more limited credit and collateral review.
 
    The  foregoing should not be taken as  a full and complete discussion of all
of the procedures undertaken in connection with a particular underwriting.  Both
GEMICO  and UGRIC consider various other  factors including, but not limited to,
reviewing sales contracts,  verifying deposits  and other  assets and  examining
additional supporting documentation in certain instances such as divorce decrees
and   separation  agreements.  Investors  should  consult  the  particular  Pool
Insurer's underwriting guidelines  for more specific  and complete  requirements
regarding  underwriting standards.  Furthermore, the  underwriting process often
results in certain compensating factors being considered to offset the existence
of other negative factors in a loan file.
 
    Neither the Certificates nor  the Mortgage Loans  are insured or  guaranteed
under a mortgage pool insurance policy issued by GEMICO or UGRIC.
 
MORTGAGE ORIGINATION PROCESSING
 
    PHMC  or  PLMSC 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  or PLMSC 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. PHMC  is
an  approved servicer of FNMA, FHLMC and GNMA. As of December 31, 1994, PHMC had
a net  worth of  approximately  $524 million.  See  "Servicing of  the  Mortgage
Loans--The Servicers" below.
 
                                USE OF PROCEEDS
 
    The  net proceeds from the sale of  each Series of Certificates will be used
by the  Seller  for  the purchase  of  the  Mortgage Loans  represented  by  the
Certificates  of such Series  from PHMC. It  is expected that  PHMC will use the
proceeds from the  sale of  the Mortgage  Loans to  the Seller  for its  general
business purposes, including, without limitation, the origination or acquisition
of  new mortgage loans and  the repayment of borrowings  incurred to finance the
origination or  acquisition  of mortgage  loans,  including the  Mortgage  Loans
underlying the Certificates of such Series.
 
                        SERVICING OF THE MORTGAGE LOANS
 
    The  following  is a  summary  of certain  provisions  of the  forms  of the
Underlying Servicing Agreement  and the  Pooling and  Servicing Agreements  that
have  been  filed  as  exhibits  to the  Registration  Statement  of  which this
Prospectus forms a part.  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  Underlying  Servicing  Agreements  and/or  the  Pooling  and
Servicing   Agreement  for  each  Series  of  Certificates  and  the  applicable
Prospectus Supplement.
 
THE MASTER SERVICER
 
    Unless otherwise specified in the related Prospectus Supplement, the  Master
Servicer  with respect to a Series of Certificates for which there are more than
one Servicer will be SASCOR. See  "SASCOR" above. Unless otherwise specified  in
the  related Prospectus Supplement, the Master  Servicer will (a) be responsible
under each Pooling and Servicing Agreement for providing general  administrative
services  for  the Trust  Estate  for any  such  Series, including,  among other
things, (i) oversight of  payments received on  Mortgage Loans, (ii)  monitoring
the  amounts  on deposit  in various  trust accounts,  (iii) calculation  of the
amounts  payable  to   Certificateholders  on  each   Distribution  Date,   (iv)
preparation  of periodic reports  to the Trustee  or the Certificateholders with
respect to the foregoing matters, (v)  preparation of federal and state tax  and
information  returns and (vi) preparation of reports, if any, required under the
Securities and Exchange Act  of 1934, as amended;  (b) administer and  supervise
the  performance by the Servicers of their duties and responsibilities under the
Underlying Servicing  Agreements;  (c)  maintain  any  mortgage  pool  insurance
 
                                       49
<PAGE>
policy, mortgagor bankruptcy bond, special hazard insurance policy or other form
of credit support that may be required; (d) make advances of delinquent payments
of  principal and interest on the Mortgage Loans to the limited extent described
herein under the  heading "Servicing  of Mortgage  Loans--Periodic Advances  and
Limitations  Thereon," if such amounts  are not advanced by  a Servicer; and (e)
perform certain  of  the  servicing  obligations of  a  terminated  Servicer  as
described  below under "Servicing of  Mortgage Loans--The Servicers." The Master
Servicer will be entitled to receive a  portion of the interest payments on  the
Mortgage  Loans included in the Trust Estate for such a Series to cover its fees
as Master Servicer. The Master Servicer  may subcontract with PHMC or any  other
entity  the administrative obligations of the  Master Servicer under any Pooling
and Servicing Agreement. The  Master Servicer will  remain primarily liable  for
any  such contractor's performance in accordance with the applicable Pooling and
Servicing Agreement. The Master Servicer may be released from its obligations in
certain circumstances.  See "Servicing  of the  Mortgage Loans--Certain  Matters
Regarding the Sole Servicer or Master Servicer."
 
THE SOLE SERVICER
 
    PHMC,  with  respect to  a Series  of  Certificates where  PHMC is  the only
Servicer of  the related  Mortgage Loans,  is referred  to herein  as the  "Sole
Servicer."  See "PHMC--Servicing" above.  The Sole Servicer  may subcontract its
servicing obligations  under  any  Pooling and  Servicing  Agreement.  The  Sole
Servicer  will remain primarily liable for any such subservicer's performance in
accordance with  the  applicable  Pooling  and  Servicing  Agreement.  The  Sole
Servicer   presently  intends  to  subcontract  certain  of  its  administrative
functions under the  Pooling and  Servicing Agreements to  SASCOR. See  "SASCOR"
above.  The  Sole  Servicer may  be  released  from its  obligations  in certain
circumstances. See "Servicing of  the Mortgage Loans--Certain Matters  Regarding
the Sole Servicer or Master Servicer."
 
    Each  Prospectus Supplement relating  to such 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.
 
    Except as  otherwise  specified  herein,  the  Sole  Servicer  will  perform
customary servicing functions as described under "--The Servicers" below.
 
THE SERVICERS
 
    For  each Series other  than those Series  where PHMC is  the Sole Servicer,
PHMC and one or  more other Servicers will  provide certain customary  servicing
functions  with  respect  to  Mortgage  Loans  pursuant  to  separate  servicing
agreements ("Underlying Servicing Agreements") with  the Seller or an  affiliate
thereof.  The  rights  of the  Seller  or  such affiliate  under  the applicable
Underlying Servicing Agreements in respect of the Mortgage Loans included in the
Trust Estate for any  such Series will be  assigned (directly or indirectly)  to
the  Trustee for such  Series. The Servicers  may be entitled  to withhold their
Servicing Fees and certain other fees  and charges from remittances of  payments
received on Mortgage Loans serviced by them.
 
    Each  Servicer generally will be approved by  FNMA or FHLMC as a servicer of
mortgage loans  and must  be approved  by the  Master Servicer.  In  determining
whether to approve a Servicer, the Master Servicer will review the credit of the
Servicer,  including capitalization  ratios, liquidity,  profitability and other
similar items that  indicate financial  ability to perform  its obligations.  In
addition,  the Master  Servicer's mortgage  servicing personnel  will review the
Servicer's servicing record and evaluate the ability of the Servicer to  conform
with  required  servicing procedures.  Generally, the  Master Servicer  will not
approve a Servicer unless the Servicer has serviced conventional mortgage  loans
for  a minimum  of three years  and maintains  a loan servicing  portfolio of at
least $500,000,000.  Servicers  approved by  the  Master Servicer  must  have  a
tangible  net worth (total  net worth less  good will) of  at least $10,000,000.
Once a Servicer is approved, the Master Servicer will continue to monitor on  an
annual basis the financial position and servicing performance of the Servicer.
 
    The  duties  to  be  performed  by  each  Servicer  include  collection  and
remittance  of  principal   and  interest  payments   on  the  Mortgage   Loans,
administration  of  mortgage escrow  accounts,  collection of  insurance claims,
foreclosure
 
                                       50
<PAGE>
procedures, and,  if necessary,  the  advance of  funds  to the  extent  certain
payments  are not  made by  the mortgagor  and have  not been  determined by the
Servicer to  be not  recoverable under  the applicable  insurance policies  with
respect  to such Series, from proceeds of  liquidation of such Mortgage Loans or
otherwise. Each  Servicer  also  will  provide  such  accounting  and  reporting
services  as are  necessary to  enable the  Master Servicer  to provide required
information to the Trustee  with respect to the  Mortgage Loans included in  the
Trust  Estate for such Series. Each Servicer is entitled to a periodic Servicing
Fee equal to a specified percentage of the outstanding principal balance of each
Mortgage Loan  serviced  by  such  Servicer. With  the  consent  of  the  Master
Servicer,  certain  servicing  obligations of  a  Servicer may  be  delegated to
another person approved by the Master Servicer.
 
    The Master Servicer or the Trustee  may terminate a Servicer who has  failed
to comply with its covenants or breached one of its representations contained in
the  Underlying  Servicing Agreement  or  in certain  other  circumstances. Upon
termination of  a Servicer  by the  Master Servicer,  the Master  Servicer  will
assume  certain servicing  obligations of  the terminated  Servicer, or,  at its
option, may  appoint a  substitute  Servicer acceptable  to the  Trustee  (which
substitute  Servicer may  be PHMC)  to assume  the servicing  obligations of the
terminated Servicer.  The Master  Servicer's obligations  to act  as a  servicer
following  the  termination  of  an  Underlying  Servicing  Agreement  will not,
however, require the Master  Servicer to (i) purchase  a Mortgage Loan from  the
Trust  due  to a  breach by  such Servicer  of a  representation or  warranty in
respect of  such Mortgage  Loan,  (ii) purchase  from  the Trust  any  converted
mortgage  loan  or  (iii)  advance  payments  of  principal  and  interest  on a
delinquent Mortgage Loan in excess of the Master Servicer's independent  advance
obligation under the Pooling and Servicing Agreement.
 
PAYMENTS ON MORTGAGE LOANS
 
    The   Sole  Servicer  or  Master  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")  and, in the case of the  Master
Servicer,  a separate trust account in the name of the Master Servicer on behalf
of the Trustee (the  "Master Servicer Custodial  Account"). The Master  Servicer
may  designate the Certificate Account as  the Master Servicer Custodial Account
for any  Series.  Each  such  account  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 in at  least one of the  two highest rating categories  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 or  the
Master  Servicer Custodial  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.
 
    Pursuant to the applicable Underlying Servicing Agreements with respect to a
Series having  more  than  one  Servicer, each  Servicer  will  be  required  to
establish  and  maintain  one  or more  accounts  (collectively,  the "Custodial
Account") into which the Servicer will be  required to deposit on a daily  basis
amounts  received  with  respect to  Mortgage  Loans serviced  by  such Servicer
included in the  Trust Estate for  such Series, as  more fully described  below.
Each  Custodial  Account must  be a  separate custodial  account insured  to the
available limits  by the  FDIC  and limited  to funds  held  with respect  to  a
particular  Series, unless the  Underlying Servicing Agreement  specifies that a
Servicer may establish an account which is either (i) an Eligible Account,  (ii)
maintained as a trust account or accounts with the trust department of a federal
or  state  chartered  depository  institution or  trust  company  acting  in its
fiduciary capacity or (iii) such other account that is acceptable to the  Master
Servicer  ("Eligible Custodial Account") to serve as a unitary Custodial Account
both for such Series and  for other Series of  Certificates for which SASCOR  is
the  Master Servicer and having the same financial institution as Trustee and to
be maintained  in the  name of  such financial  institution, in  its  respective
capacities as Trustee for each such Series.
 
    Each  Servicer will be required to  deposit in the Master Servicer Custodial
Account for each  Series of Certificates  having more than  one Servicer on  the
date  the Certificates are issued any amounts representing scheduled payments of
principal and interest on the Mortgage Loans serviced by such Servicer due after
the applicable Cut-Off Date but
 
                                       51
<PAGE>
received on or prior thereto, and except as specified in the applicable  Pooling
and  Servicing Agreement or Underlying Servicing  Agreement, will deposit in the
Custodial Account on receipt and, thereafter,  not later than the 18th  calendar
day  of  each month  or such  other day  as  may be  specified in  the Servicing
Agreement (the "Remittance Date"), will remit to the Master Servicer for deposit
in the Master Servicer Custodial Account, the following payments and collections
received or made by such Servicer with respect to the Mortgage Loans serviced by
such Servicer subsequent to the applicable Cut-Off Date (other than (x) payments
due on or before the Cut-Off Date and (y) amounts held for future distribution).
In the case  of a Series  having a single  Servicer, the Sole  Servicer will  be
required to deposit such amounts in the Certificate Account on a daily basis:
 
         (i)  all payments on  account of principal,  including prepayments, and
    interest;
 
        (ii) all amounts received by the Applicable 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
    Servicing  Agreement, the amount of any expenses incurred in connection with
    the liquidation of such Mortgage Loans;
 
        (iii) all proceeds received by the Applicable 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
    Servicing Agreement;
 
        (iv) all Periodic Advances made by the Applicable Servicer;
 
        (v)  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;
 
        (vi)  all proceeds  of any such  Mortgage Loans or  property acquired in
    respect thereof  purchased  or  repurchased  pursuant  to  the  Pooling  and
    Servicing Agreement or the Underlying Servicing Agreement; and
 
       (vii)  all other amounts required to be deposited therein pursuant to the
    applicable Pooling  and  Servicing  Agreement or  the  Underlying  Servicing
    Agreement.
 
    Notwithstanding  the foregoing, if at any time the sums in (x) any Custodial
Account other than  any Eligible Custodial  Account exceed $100,000  or (y)  any
Custodial  Account,  in  certain  circumstances, exceed  such  amount  less than
$100,000 as shall have been specified by the Master Servicer, the Servicer  will
be  required within  one business  day to withdraw  such excess  funds from such
account and remit such amounts to the Master Servicer Custodial Account.
 
    Notwithstanding the foregoing, each Applicable 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 Custodial Account, or Certificate Account in the case of
the Sole Servicer, or (b) to withdraw from the Custodial Account, or Certificate
Account in the case  of the Sole Servicer,  the applicable Servicing Fee  and/or
the  Fixed Retained Yield, if any, after the entire payment or recovery has been
deposited in such account;  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, each Applicable 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 Custodial Account, or Certificate Account in the case
of the Sole Servicer.
 
    The  Master Servicer will  deposit in the  Master Servicer Custodial Account
any Periodic Advances made  by the Master  Servicer in the  event of a  Servicer
default, amounts withdrawn from any reserve fund and amounts available under any
other  form of credit enhancement not later  than the Distribution Date on which
such amounts are required to be distributed. All other amounts will be deposited
in the Master Servicer  Custodial Account not later  than the business day  next
following  the day of receipt  and posting by the  Master Servicer. On or before
each Distribution  Date,  the Master  Servicer  will withdraw  from  the  Master
Servicer  Custodial Account  and remit  to the  Certificate Account  all amounts
allocable to the Pool Distribution Amount for such Distribution Date.
 
    If the Master Servicer or Sole Servicer or a Servicer deposits in the Master
Servicer Custodial Account or  the Certificate Account for  a Series any  amount
not  required  to be  deposited therein,  the Master  Servicer or  Sole Servicer
 
                                       52
<PAGE>
may at  any time  withdraw  such amount  from such  account  for itself  or  for
remittance  to  such Servicer,  as applicable.  Funds on  deposit in  the Master
Servicer Custodial Account or 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 Master  Servicer or  Sole
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
Master  Servicer or Sole Servicer as additional compensation and all losses from
any such investment will  be deposited by the  Master Servicer or Sole  Servicer
out of its own funds to the Master Servicer Custodial Account or the Certificate
Account, as applicable, immediately as realized.
 
    The  Master Servicer  is permitted, from  time to time,  to make withdrawals
from the Master Servicer  Custodial Account or the  Certificate Account and  the
Sole  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 (and,  in  the  case  of Servicer
reimbursements by  the  Master  Servicer,  only  to  the  extent  funds  in  the
respective Custodial Account are not sufficient therefor):
 
         (i) to reimburse itself in the case of the Sole Servicer or itself, the
    Trustee or any Servicer in the case of the Master Servicer for Advances;
 
        (ii)  to reimburse itself in the case  of the Sole Servicer or itself or
    any Servicer in the case of the Master Servicer for liquidation expenses and
    for amounts expended by itself or any Servicer, as applicable, in connection
    with the restoration of damaged property;
 
        (iii) to pay to itself the applicable Master Servicing Fee or  Servicing
    Fee and any other amounts constituting additional servicing compensation; or
    to  pay to  the owner  thereof any  Fixed Retained  Yield, in  the event the
    Servicer, including the Sole 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  Master  Servicer  Custodial  Account  or  the  Certificate
    Account;
 
        (iv)  to reimburse itself in the case  of the Sole Servicer or itself or
    any Servicer  in  the case  of  the  Master Servicer  for  certain  expenses
    (including  taxes  paid  on behalf  of  the  Trust Estate)  incurred  by and
    recoverable by or reimbursable to itself or the Servicer, as applicable;
 
        (v) to pay to the  Seller, the Sole Servicer  or itself with respect  to
    each  Mortgage Loan  or property acquired  in respect thereof  that has been
    repurchased by the Seller  or purchased by the  Sole Servicer or the  Master
    Servicer,  respectively, 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 to itself any interest earned on or investment income earned
    with  respect  to funds  in  the Master  Servicer  Custodial Account  or the
    Certificate Account (all such interest or  income to be withdrawn not  later
    than the next Distribution Date);
 
       (vii)  to pay to itself in the case of the Sole Servicer or itself or the
    Servicer in  the  case of  the  Master  Servicer, as  applicable,  from  net
    Liquidation  Proceeds allocable to interest, the amount of any unpaid Master
    Servicing Fee or Servicing Fees and any unpaid assumption fees, late payment
    charges or other mortgagor charges on the related Mortgage Loan;
 
       (viii) to  withdraw from  the Master  Servicer Custodial  Account or  the
    Certificate  Account  any  amount deposited  in  such 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 Master Servicer Custodial Account or the
    Certificate Account.
 
                                       53
<PAGE>
    The Master Servicer or Sole Servicer will be authorized to appoint a  paying
agent  (the  "Paying Agent")  to  make distributions,  as  agent for  the Master
Servicer or Sole  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 Master Servicer  or Sole 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 Master Servicer or  Sole 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 Master Servicer or  Sole
    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  Master Servicer or
    Sole 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 involving  the Sole Servicer, the Sole Servicer
will agree to make Periodic Advances in the amounts specified in the  applicable
Prospectus Supplement. Funds of the Sole Servicer so advanced are recoverable by
the  Sole 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
Sole Servicer determines that  any Periodic Advance may  not be so  recoverable,
out  of  any funds  in  the Certificate  Account.  The Sole  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 Sole Servicer.  Any
such  reserve fund will be funded by a deposit made by the Sole Servicer in such
an amount  specified, and  will otherwise  be as  described, in  the  applicable
Prospectus Supplement.
 
    Generally,  in the case of  a Series involving more  than one Servicer, each
Servicer will be  required to  make (i)  Periodic Advances  to cover  delinquent
payments of principal and interest on such Mortgage Loan and (ii) other advances
of  cash ("Other Advances") to cover (x) delinquent payments of taxes, insurance
premiums,  and  other  escrowed  items  and  (y)  rehabilitation  expenses   and
foreclosure  costs, including reasonable attorneys'  fees, in either case unless
such Servicer has determined that any subsequent payments on that Mortgage  Loan
or from the borrower will ultimately not be available to reimburse such Servicer
for  such amounts.  The failure  of the Servicer  to make  any required Periodic
Advances or Other Advances under an Underlying Servicing Agreement constitutes a
default under such  agreement for which  the Servicer will  be terminated.  Upon
default  by the Servicer, the Master Servicer  or Trustee may, if so provided in
the Pooling and Servicing  Agreement, be required to  make Periodic Advances  to
the  extent necessary to make required  distributions on certain Certificates or
certain Other Advances, provided that the Master Servicer or Trustee  determines
that  funds  will  ultimately be  available  to  reimburse it.  In  the  case of
Certificates of any Series for which credit enhancement is provided in the  form
of a mortgage pool insurance policy, the Seller may obtain an endorsement to the
mortgage  pool  insurance policy  which obligates  the  Pool Insurer  to advance
delinquent payments of principal  and interest. The Pool  Insurer would only  be
obligated  under such endorsement to the extent the mortgagor fails to make such
payment and  the  Servicer and  the  Master Servicer  fail  to make  a  required
advance.
 
    The  Advance obligation of the Master Servicer or the Trustee may be further
limited to an amount specified by the Rating Agency rating the Certificates. Any
such Periodic Advances by the Servicers, the Master Servicer or the Trustee,  as
the case may be, must be deposited into the applicable Custodial Account or into
the Master Servicer Custodial Account or the Certificate Account and will be due
no  later  than the  business day  before  the Distribution  Date to  which such
delinquent payment relates. Advances  by the Servicers,  the Master Servicer  or
the  Trustee, as the case may be, will be reimbursable out of insurance proceeds
or Liquidation Proceeds of, or, except  for Other Advances, future payments  on,
the Mortgage Loans for which such amounts were advanced. If an Advance made by a
Servicer, the
 
                                       54
<PAGE>
Master Servicer or the Trustee later proves, or is deemed by the Master Servicer
or  the Trustee, to be unrecoverable, such  Servicer, the Master Servicer or the
Trustee, as the case may be, will be entitled to reimbursement from funds in the
Certificate  Account   prior   to   the  distribution   of   payments   to   the
Certificateholders   to  the  extent  provided  in  the  Pooling  and  Servicing
Agreement.
 
    If specified in the applicable Prospectus Supplement, a reserve fund  (which
may  be held outside the Trust) may be established with respect to any Series of
Certificates in order to provide a source of liquidity for Periodic Advances  by
a  Servicer, the Master Servicer  or the Trustee. Any  such reserve fund will be
funded by a  deposit made by  such Servicer or  the Master Servicer  in such  an
amount  specified,  and  will  otherwise  be  as  described,  in  the applicable
Prospectus Supplement.
 
    Any Periodic Advances made by a Servicer or the Master Servicer with respect
to Mortgage Loans included in  the Trust Estate for  any Series are intended  to
enable  the Trustee  to make  timely payment  of the  scheduled distributions of
principal and interest on the Certificate  of such Series. However, neither  the
Master  Servicer,  the Trustee  nor any  Servicer will  insure or  guarantee the
Certificates of any Series  or the Mortgage Loans  included in the Trust  Estate
for any Certificates.
 
ADJUSTMENT TO SERVICING FEE IN CONNECTION WITH PREPAID MORTGAGE LOANS
 
    When  a mortgagor prepays all or part of a Mortgage Loan, the mortgagor pays
interest on  the  amount  prepaid  only  to the  date  on  which  the  principal
prepayment  is applied to the principal balance thereof. To the extent specified
in the applicable Prospectus Supplement, in order to mitigate the adverse effect
to Certificateholders of a  Series resulting from the  prepayment of a  Mortgage
Loan  or a portion  thereof, the amount  of the aggregate  Servicing Fees may be
offset by an amount equal to the related interest shortfall. Any such reductions
in the aggregate  Servicing Fees will  be made by  the Applicable Servicer  with
respect to the Mortgage Loans under the applicable Servicing Agreement, but only
to  the  extent  of the  aggregate  amount  of any  Servicing  Fees  relating to
mortgagor payments or other recoveries  distributed on the related  Distribution
Date.  The amount  of any  offset against the  aggregate Servicing  Fees will be
included in the distributions to Certificateholders on the Distribution Date  on
which    the   related    principal   prepayments   are    passed   through   to
Certificateholders.
 
    Unless such  an offset  against  Servicing Fees  with respect  to  principal
prepayments  or another form of offset is specified in the applicable Prospectus
Supplement, any interest shortfall arising  from full or partial prepayments  or
liquidations will not be so offset. See "Prepayment and Yield Considerations."
 
REPORTS TO CERTIFICATEHOLDERS
 
    Unless  otherwise specified or modified in the related Pooling and Servicing
Agreement for each Series,  the Sole Servicer or  Master 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:

    Certificate,  the amount of such distribution  allocable to principal of the
    related Mortgage Loans, separately identifying  the aggregate amount of  any
    principal  prepayments  included therein,  the  amount of  such distribution
    allocable to interest on the related Mortgage Loans and the aggregate unpaid
    principal balance of the Mortgage Loans evidenced by each Class after giving
    effect to the principal distributions on such Distribution Date;
 
        (ii) to each holder  of a Multi-Class Certificate  on which an  interest
    distribution and a distribution in reduction of Stated Amount are then being
    made, the amount of such interest distribution and distribution in reduction
    of Stated Amount, and the Stated Amount of each Class after giving effect to
    the  distribution in  reduction of Stated  Amount made  on such Distribution
    Date;
 
        (iii)  to  each  holder  of   a  Multi-Class  Certificate  on  which   a
    distribution  of  interest only  is then  being  made, the  aggregate Stated
    Amount of Certificates outstanding of each Class after giving effect to  the
    distribution  in reduction of  Stated Amount made  on such Distribution Date
    and on any Special Distribution Date  occurring subsequent to the last  such
    report  and after including in the aggregate Stated 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;
 
                                       55
<PAGE>
        (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  Sole  Servicer  or  Master  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

       (vii) the aggregate amount  of any Periodic Advances  by the Servicer  or
    the  Master  Servicer  or Sole  Servicer  included in  the  amounts actually

    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;

    through foreclosure or otherwise;
 
        (xii) the unpaid principal balance of any Mortgage Loan as to which  the
    Servicer has notified the Master Servicer that such Servicer, or as to which
    the  Sole 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  Sole  Servicer  or  Master  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
 
                                       56
<PAGE>
regulations  thereunder  and  as  the Sole  Servicer  or  Master  Servicer deems
necessary or  desirable  to  enable  Certificateholders  to  prepare  their  tax
returns.  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 Sole Servicer or  Master Servicer). See "Certain Federal  Income
Tax Consequences-- Administrative Matters."

    No  later than 15 days  after each Distribution Date  for a Series, the Sole
Servicer or  Master 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 Sole Servicer or Master Servicer under the applicable Pooling and
Servicing Agreement have been made (or if any required distribution has not been
made  by the Sole Servicer or Master  Servicer, specifying the nature and status
thereof) and showing, for the period covered by such statement, the aggregate of
deposits to and withdrawals  from the Certificate Account  for each category  of
deposits  and withdrawals specified in the Pooling and Servicing Agreement. Such
statement shall  also  include  information  as  to  (i)  the  aggregate  unpaid
principal  balances of all the Mortgage Loans as of the close of business on the
last day  of the  month preceding  the  month in  which such  Distribution  Date
occurs;  and (ii)  the amount  of any Subordination  Reserve Fund  and any other
reserve fund,  as  of  such  Distribution  Date  (after  giving  effect  to  the
distributions on such Distribution Date). Copies of such reports may be obtained
by  Certificateholders upon request  in writing addressed  to the Sole Servicer,
c/o The Prudential Home Mortgage Company, Inc., 5325 Spectrum Drive,  Frederick,
Maryland 21701 or the Master Servicer, 7485 New Horizon Way, Frederick, Maryland
20701.  If the  Sole Servicer  or Master  Servicer should  fail to  provide such
copies, they may be obtained from the Trustee, as applicable.
 
COLLECTION AND OTHER SERVICING PROCEDURES
 
    Each Applicable  Servicer  will  make  reasonable  efforts  to  collect  all
payments  called  for under  the Mortgage  Loans and  will, consistent  with the
applicable 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  Applicable  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  Servicing  Agreement, each  Applicable  Servicer, to  the  extent
permitted  by law, will establish and maintain  one or more escrow accounts (the
"Servicing Account") in which each such 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.
Each Applicable  Servicer will  be  responsible for  the administration  of  its
Servicing Account. A 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,  a Servicer may procure  a performance bond or  other form of insurance
coverage, in  an amount  acceptable to  the Master  Servicer and  Rating  Agency
rating  the  related Series  of Certificates,  covering  loss occasioned  by the
failure to escrow such amounts.
 
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,  the applicable
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 Applicable Servicer's judgment, be reasonably likely to result in
litigation by the mortgagor and such Servicer (other than the Sole Servicer) has
not obtained the Master Servicer's consent to such exercise. In either case, the
Servicer is authorized  to take  or enter  into an  assumption and  modification
 
                                       57
<PAGE>
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  Applicable  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.
 
    Each Underlying Servicing Agreement and Pooling and Servicing Agreement with
respect  to a Series  will require the  Servicer or the  Master Servicer or Sole
Servicer, as  the case  may  be, to  present claims  to  the insurer  under  any
insurance  policy applicable to the Mortgage  Loans included in the Trust Estate
for such Series and  to take such  reasonable steps as  are necessary to  permit
recovery under such insurance policies with respect to defaulted Mortgage Loans,
or losses on the Mortgaged Property securing the Mortgage Loans.
 
    Each  Applicable  Servicer  is  obligated  under  the  applicable  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 applicable 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 Applicable Servicer's  judgment, the default is unlikely
to be  cured and  the  assuming borrower  meets PHMC's  applicable  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, an
Applicable 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 Applicable Servicer will not
be 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 to the Applicable Servicer
for its expenses and (ii) that such  expenses will be recoverable to it  through
Liquidation  Proceeds  or any  applicable insurance  policy  in respect  of such
Mortgage Loan. In  the event that  an Applicable Servicer  has expended its  own
funds  for foreclosure or to restore damaged property, it will be entitled to be
reimbursed from the Master Servicer Custodial Account or the Certificate Account
for such Series an amount equal to all costs and expenses incurred by it.
 
    The Sole  Servicer is  not obligated  to, and  any other  Servicer will  not
(except  with the express written approval of the Master Servicer), 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 an  Applicable Servicer does
not foreclose on  a Mortgaged  Property, the Certificateholders  of the  related
Series  may  experience  a loss  on  the  related Mortgage  Loan.  An Applicable
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,  an Applicable 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  Applicable 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 and will not be
required under the applicable 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
 
                                       58
<PAGE>
Mortgage  Loan  secured by  such Mortgaged  Property or  if the  Master Servicer
determines at any  time that  any Mortgage Loan  is not  a "Qualified  Mortgage"
under  Code Section  860G, the  Trustee or Master  Servicer will  be required to
dispose of such property within two years following its acquisition by the Trust
Estate unless the Trustee (a) receives an opinion of counsel to the effect  that
the  holding of the  Mortgaged Property by  the Trust Estate  will not cause the
Trust Estate to be  subject to the tax  on "prohibited transactions" imposed  by
Code  Section 860F(a)(1) or  cause the Trust  Estate (or any  segregated pool of
assets therein as to which a REMIC election  has been made or would be made)  to
fail to qualify as a REMIC or (b) applies for and is granted an extension of the
two-year  period  in  the manner  contemplated  by Code  Section  856(e)(3). The
Applicable Servicer also will be  required to administer the Mortgaged  Property
in  a manner which does  not cause the Mortgaged Property  to fail to qualify as
"foreclosure property" within the meaning  of Code Section 860G(a)(8) or  result
in the receipt by the Trust Estate of any "net income from foreclosure property"
within  the meaning of  Code Section 860G(c)(2),  respectively. In general, this
would preclude the  holding of the  Mortgaged Property  by a party  acting as  a
dealer  in such property or the receipt of rental income based on the profits of
the lessee of such property. See "Certain Federal Income Tax Consequences."
 
FIXED RETAINED YIELD, SERVICING COMPENSATION AND PAYMENT OF EXPENSES
 
    Fixed Retained Yield with respect to  any Mortgage Loan is that portion,  if
any,  of interest  at the  Mortgage Interest  Rate that  is not  included in the
related Trust  Estate.  The Prospectus  Supplement  for a  Series  will  specify
whether  there is any Fixed Retained Yield with respect to the Mortgage Loans of
such Series.  If  so,  the  Fixed  Retained  Yield  will  be  established  on  a
loan-by-loan  basis  and will  be specified  in the  schedule of  Mortgage Loans
attached as  an  exhibit to  the  applicable Pooling  and  Servicing  Agreement.
Servicers  other than PHMC will be required  to deposit in the Custodial Account
for remittance  to the  Master Servicer  the Fixed  Retained Yield,  if any,  as
received.  PHMC as Servicer or Sole Servicer may deduct the Fixed Retained Yield
from mortgagor payments as received and prior to deposit of such payments in the
Custodial Account or Certificate  Account for such Series  or may withdraw  from
the  Custodial Account or Certificate Account, or request the Master Servicer to
withdraw from the Master Servicer  Custodial Account or Certificate Account  for
remittance  to PHMC as Servicer or Sole Servicer, the Fixed Retained Yield after
the  entire   payment   has  been   deposited   in  the   Certificate   Account.
Notwithstanding  the foregoing, with respect to any payment of interest received
by PHMC as Servicer or Sole 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, each  Applicable Servicer will be entitled
to be paid  the Servicing Fee  on the  related Mortgage Loans  serviced by  such
Servicer  until  termination  of the  applicable  Servicing  Agreement, subject,
unless  otherwise  specified  in   the  applicable  Prospectus  Supplement,   to
adjustment  as described under  "Adjustment to Servicing  Fee in Connection with
Prepaid Mortgage  Loans." A  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 Custodial Account or Certificate Account for such Series  or
(b)  withdrawing the  Servicing Fee  from the  Custodial Account  or Certificate
Account after the entire interest payment has been deposited in such account.  A
Servicer  may also pay itself out of the Liquidation Proceeds of a Mortgage Loan
or other recoveries with respect thereto, or withdraw from the Custodial Account
or Certificate  Account or  request the  Master Servicer  to withdraw  from  the
Master  Servicer Custodial Account or the  Certificate Account for remittance to
the Servicer such amounts after the deposit thereof in such accounts, 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.
 
    Each  Servicer  will  pay  all  expenses  incurred  in  connection  with the
servicing of the Mortgage Loans serviced  by such Servicer underlying a  Series,
including,  without limitation, payment of the hazard insurance policy premiums.
The Servicer will be entitled,  in certain circumstances, to reimbursement  from
the  Master Servicer  Custodial Account or  the Certificate  Account of Periodic
Advances, of Other  Advances made  by it to  pay taxes,  insurance premiums  and
similar
 
                                       59
<PAGE>
items  with respect to any Mortgaged Property or for expenditures incurred by it
in connection with the restoration or foreclosure of any Mortgaged Property  (to
the  extent of Liquidation  Proceeds or insurance policy  proceeds in respect of
such Mortgaged Property) and of certain  losses against which it is  indemnified
by the Trust Estate.
 
    As  set forth  in the  preceding paragraph,  a Servicer  may 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  Master  Servicer or  Sole Servicer  will pay  all expenses  incurred in
connection with  the  administration of  the  Trust Estate,  including,  without
limitation,  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
Master Servicer or Sole Servicer pursuant to the terms of the applicable Pooling
and Servicing Agreement.
 
EVIDENCE AS TO COMPLIANCE
 
    The  Sole Servicer or each Servicer will  deliver annually to the Trustee or
Master Servicer,  as  applicable,  on  or  before  the  date  specified  in  the
applicable  Servicing  Agreement, an  Officer's Certificate  stating that  (i) a
review of the activities of such Servicer during the preceding calendar year and
of performance under the applicable 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, such Servicer has fulfilled all its obligations under  the
applicable  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  such
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 applicable  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.
 
    Each  year the Master Servicer will review each Servicer's performance under
its Underlying  Servicing Agreement  and the  status of  any fidelity  bond  and
errors and omissions policy required to be maintained by such Servicer under the
Underlying Servicing Agreement.
 
CERTAIN MATTERS REGARDING THE SOLE SERVICER OR MASTER SERVICER
 
    The Sole Servicer or Master 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  Sole  Servicer's  or  Master  Servicer's
obligations and duties under  the Pooling and Servicing  Agreement. If the  Sole
Servicer  or Master 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  "The Pooling  and  Servicing Agreement--Rights  Upon  Event of
Default" below.
 
    The Pooling and Servicing Agreement will also provide that neither the  Sole
Servicer  or  Master  Servicer,  any  subservicer,  nor  any  partner, director,
officer, employee or agent of either of them, 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 Sole  Servicer or  Master 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 Sole Servicer or Master Servicer, any subservicer,  and
any  partner, director, officer,  employee or agent  of either of  them shall be
entitled  to   indemnification  by   the   Trust  Estate   and  will   be   held
 
                                       60
<PAGE>
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 Sole Servicer  or Master 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 Sole Servicer  or
Master  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 Sole Servicer or Master Servicer will be
entitled  to be  reimbursed therefor  out of  the Certificate  Account or Master
Servicer Custodial 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.
 
    Any  person into which the Sole Servicer or Master Servicer may be merged or
consolidated,  or  any   person  resulting  from   any  merger,  conversion   or
consolidation  to which the Sole Servicer or  Master Servicer is a party, or any
person succeeding to the business through  the transfer of substantially all  of
its  assets, or otherwise, of  the Sole Servicer or  Master Servicer will be the
successor of  the  Sole  Servicer  or Master  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 in the  case
of  a  successor  to  the  Sole  Servicer has  a  net  worth  of  not  less than
$15,000,000.
 
    The Sole Servicer or Master 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
reasonable exercise of its 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 Sole Servicer or Master 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 would not be qualified, downgraded or
withdrawn as a result of such assignment, sale or transfer and the  Certificates
would  not be placed on credit review status by any such Rating Agency. The Sole
Servicer or Master  Servicer will  be released  from its  obligations under  the
Pooling  and Servicing Agreement upon any such assignment and delegation, except
that the Sole Servicer or Master 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.
 
                      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 Sole Servicer or Master Servicer to distribute to
Certificateholders any  required payment  which continues  unremedied for  three
business  days after the  giving of written  notice of such  failure to the Sole
Servicer or Master  Servicer by  the Trustee  for such  Series, or  to the  Sole
Servicer  or Master 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  Sole
Servicer  or Master Servicer by  the Trustee, or to  the Sole Servicer or Master
Servicer and the  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  Sole  Servicer  or  Master  Servicer
 
                                       61
<PAGE>
indicating its insolvency,  reorganization or inability  to pay its  obligations
and (iv) both the Sole Servicer or Master 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 Sole  Servicer  or Master  Servicer  under the  Pooling and
Servicing Agreement  and in  and to  the  Mortgage Loans  (other than  the  Sole
Servicer's  or Master  Servicer's right to  recovery of any  Initial Deposit for
such Series, the aggregate Servicing Fees or Master 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 Sole Servicer or
Master 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 or  Master
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 Sole Servicer or Master 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 Sole Servicer or Master Servicer
is appointed and 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 Sole Servicer or Master 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 or Master 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 Sole  Servicer or Master 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  Sole
Servicer  or  Master  Servicer  and  the  Trustee  without  the  consent  of the
Certificateholders, (i) to  cure any ambiguity  or mistake, (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
 
                                       62
<PAGE>
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,"
(vi) to make certain  provisions with respect to  the denominations of, and  the
manner  of payments on, certain Classes  or Subclasses of Certificates initially
retained by the Seller or  an affiliate, or (vii)  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  Sole Servicer or  Master Servicer and  the Trustee with  the consent of the
holders of Certificates evidencing interests  aggregating not less than 66  2/3%
of  the Voting Interests evidenced by the Certificates of each Class or Subclass
affected thereby, for the purpose of adding any provisions to or changing in any
manner or  eliminating any  of  the provisions  of  such Pooling  and  Servicing
Agreement  or of modifying  in any manner the  rights of the Certificateholders;
provided, however,  that no  such amendment  may (i)  reduce in  any manner  the
amount  of, or delay the timing of, any  payments received on or with respect to
Mortgage Loans that are required to be distributed on any Certificates,  without
the  consent of  the holder  of such Certificate,  (ii) adversely  affect in any
material respect  the  interests  of the  holders  of  a Class  or  Subclass  of
Certificates  of a  Series in a  manner other than  that set forth  in (i) above
without the consent  of the holders  of Certificates aggregating  not less  than
66  2/3% of the Voting  Interests evidenced by such  Class or Subclass, or (iii)
reduce the aforesaid percentage  of Certificates of any  Class or Subclass,  the
holders  of which are required to consent to such amendment, without the consent
of the  holders of  all Certificates  of such  Class or  Subclass affected  then
outstanding.  Notwithstanding the foregoing, the Trustee will not consent to any
such amendment if such amendment would subject the Trust Estate (or a segregated
pool of assets therein) to tax or  cause the Trust Estate (or a 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  Sole Servicer  or  Master
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 or other evidence  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  Trust
Estate  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
 
                                       63
<PAGE>
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  Sole Servicer  or
Master  Servicer  will be  obligated to  appoint a  successor trustee.  The Sole
Servicer or Master 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  Sole
Servicer  or  Master  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
Sole Servicer or Master Servicer or any affiliate thereof will not be taken into
account in determining whether the requisite Voting Interest in the Trust Estate
necessary  to effect  any such  removal has  been obtained.  Any resignation and
removal of the  Trustee, and the  appointment of a  successor trustee, will  not
become  effective until acceptance of such appointment by the successor trustee.
The Trustee, and any successor trustee, will have a combined capital and surplus
of at least  $50,000,000, or  will be  a member of  a bank  holding system,  the
aggregate  combined  capital  and  surplus of  which  is  at  least $50,000,000,
provided that the Trustee's  and any such  successor trustee's separate  capital
and  surplus shall  at all  times be  at least  the amount  specified in Section
310(a)(2) of the Trust Indenture Act of 1939, and will be subject to supervision
or examination by federal or state authorities.
 
                  CERTAIN LEGAL ASPECTS OF THE MORTGAGE LOANS
 
    The following  discussion contains  summaries of  certain legal  aspects  of
mortgage  loans  which are  general in  nature. Because  such legal  aspects are
governed by  applicable state  law (which  laws may  differ substantially),  the
summaries do not purport to be complete or to reflect the laws of any particular
state,  nor to encompass  the laws of all  states in which  the security for the
Mortgage Loans is  situated. The summaries  are qualified in  their entirety  by
reference to the applicable federal and state laws governing the Mortgage Loans.
 
GENERAL
 
    The Mortgage Loans will, in general, be secured by either first mortgages or
first  deeds of trust,  depending upon the  prevailing practice in  the state in
which the underlying  property is located.  A mortgage creates  a lien upon  the
real  property described in the  mortgage. There are two  parties to a mortgage:
the mortgagor, who is the borrower; and  the mortgagee, who is the lender. In  a
mortgage  state instrument,  the mortgagor delivers  to the mortgagee  a note or
bond evidencing the loan and the mortgage.  Although a deed of trust is  similar
to  a mortgage, a deed of trust has three parties: a borrower called the trustor
(similar to  a  mortgagor),  a  lender called  the  beneficiary  (similar  to  a
mortgagee), and a third-party grantee called the trustee. Under a deed of trust,
the  borrower grants the property, irrevocably until the debt is paid, in trust,
generally with a power of  sale, to the trustee to  secure payment of the  loan.
The  trustee's authority  under a  deed of  trust and  the mortgagee's authority
under a mortgage are governed by the express provisions of the deed of trust  or
mortgage, applicable law, and, in some cases, with respect to the deed of trust,
the directions of the beneficiary.
 
FORECLOSURE
 
    Foreclosure  of  a mortgage  is generally  accomplished by  judicial action.
Generally, the action is  initiated by the service  of legal pleadings upon  all
parties  having an interest of record in the real property. Delays in completion
of the  foreclosure  occasionally  may  result  from  difficulties  in  locating
necessary  parties  defendant.  When  the mortgagee's  right  of  foreclosure is
contested,  the  legal  proceedings  necessary  to  resolve  the  issue  can  be
time-consuming.  After the completion of  a judicial foreclosure proceeding, the
court may  issue a  judgment of  foreclosure  and appoint  a receiver  or  other
officer  to conduct the sale of the property. In some states, mortgages may also
be foreclosed by  advertisement, pursuant  to a power  of sale  provided in  the
mortgage.  Foreclosure of a mortgage by  advertisement is essentially similar to
foreclosure of a deed of trust by non-judicial power of sale.
 
                                       64
<PAGE>
    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 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.
 
                                       65
<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.
 
    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.
 
                                       66
<PAGE>
    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.
 
    A Servicer generally  will not  be required under  the applicable  Servicing
Agreement,  and the  Sole Servicer  will not be  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,
numerous statutory provisions under the United States Bankruptcy Code, 11 U.S.C.
SectionSection101 ET. SEQ., (the "Bankruptcy Code") may interfere with or affect
the  ability of the Seller to obtain payment of a Mortgage Loan, to realize upon
collateral and/or  enforce a  deficiency judgment.  For example,  under  federal
bankruptcy  law,  virtually  all  actions  (including  foreclosure  actions  and
deficiency judgment proceedings) are automatically  stayed upon the filing of  a
bankruptcy petition, and often no interest or principal payments are made during
the  course of the bankruptcy  proceeding. In a case  under the Bankruptcy Code,
the secured party is precluded  from foreclosing without authorization from  the
bankruptcy  court. In addition, a court with federal bankruptcy jurisdiction may
permit a debtor  through his  or her Chapter  11 or  Chapter 13 plan  to cure  a
monetary  default in respect  of a Mortgage  Loan by paying  arrearages within a
reasonable time  period  and  reinstating the  original  mortgage  loan  payment
schedule even though the lender accelerated the mortgage loan and final judgment
of foreclosure had been entered in state court (provided no foreclosure sale had
yet  occurred) prior to  the filing of  the debtor's petition.  Some courts with
federal bankruptcy jurisdiction  have approved  plans, based  on the  particular
facts of the case, that effected the curing of a mortgage loan default by paying
arrearages over a number of years.
 
    If  a Mortgage  Loan is  secured by  property NOT  consisting solely  of the
debtor's principal residence,  the Bankruptcy  Code also  permits such  Mortgage
Loan  to be modified. Such modifications may include reducing the amount of each
monthly payment, changing the rate of interest, altering the repayment schedule,
and reducing the lender's security interest  to the value of the property,  thus
leaving  the lender  in the  position of  a general  unsecured creditor  for the
difference between the value of the property and the outstanding balance of  the
Mortgage  Loan. Some courts have permitted  such modifications when the Mortgage
Loan is  secured  both by  the  debtor's  principal residence  and  by  personal
property.
 
    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
 
                                       67
<PAGE>
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  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 ("CERCLA"), 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. Under the
laws of certain states, failure to perform the remediation required or  demanded
by  the state of any condition or circumstance  that (i) may pose an imminent or
substantial endangerment to  the public  health or welfare  or the  environment,
(ii)  may result in a release or threatened release of any hazardous substances,
or (iii) may give rise to any environmental  claim or demand may give rise to  a
lien   on  the  property  to  ensure  the  reimbursement  of  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.
 
    The state of  the law  is currently  unclear as  to whether  and under  what
circumstances  Cleanup Costs, or the obligation  to take remedial actions, could
be imposed on a secured lender such as the Trust Estate. Under the laws of  some
states  and under CERCLA, a  lender may be liable as  an "owner or operator" for
costs of addressing releases or threatened releases of hazardous substances on a
mortgaged property if such lender or  its agents or employees have  participated
in   the  management  of  the  operations  of  the  borrower,  even  though  the
environmental damage or threat was caused by  a prior owner or current owner  or
operator  or other third  party. Excluded from CERCLA's  definition of "owner or
operator," however, is a person "who without participating in the management  of
the  facility,  holds indicia  of ownership  primarily  to protect  his security
interest" (the "secured-creditor  exemption"). This exemption  for holders of  a
security interest such as a secured lender applies only when the lender seeks to
protect its security interest in the contaminated facility or property. Thus, if
a  lender's  activities  begin to  encroach  on  the actual  management  of such
facility or  property, the  lender faces  potential liability  as an  "owner  or
operator" under CERCLA. Similarly, when a lender forecloses and takes title to a
contaminated  facility  or  property,  the  lender  may  incur  potential CERCLA
liability in various circumstances,  including among others,  when it holds  the
facility  or  property  as  an investment  (including  leasing  the  facility or
property to a third party), fails to market the property in a timely fashion  or
fails to properly address environmental conditions at the property or facility.
 
    A  decision  in May  1990  of the  United States  Court  of Appeals  for the
Eleventh Circuit in UNITED STATES V. FLEET FACTORS CORP. very narrowly construed
CERCLA's secured-creditor exemption. The court's opinion suggests that a  lender
need  not have involved itself  in the day-to-day operations  of the facility or
participated in decisions relating to hazardous waste to be liable under CERCLA;
rather, liability  could  attach  to  a  lender  if  its  involvement  with  the
management  of the facility  is broad enough  to support the  inference that the
lender had  the capacity  to  influence the  borrower's treatment  of  hazardous
waste.  The court  added that  a lender's  capacity to  influence such decisions
could be inferred from the extent of its involvement in the facility's financial
management. A subsequent decision by the United States Court of Appeals for  the
Ninth Circuit in IN RE BERGSOE METAL CORP., apparently disagreeing with, but not
expressly contradicting, the FLEET FACTORS court, held that a secured lender had
no  liability absent "some actual management of the facility" on the part of the
lender. On April  29, 1992,  the United States  Environmental Protection  Agency
(the   "EPA")  issued  a  final   rule  interpreting  and  delineating  CERCLA's
secured-creditor exemption  and the  range of  permissible actions  that may  be
undertaken  by a holder of a  contaminated facility without exceeding the bounds
of the secured-creditor exemption. On February 4, 1994, the United States  Court
of Appeals for the District of Columbia Circuit in KELLEY V. EPA invalidated the
EPA  rule. As a result of the KELLEY case,  the state of the law with respect to
the secured creditor  exemption remains unclear.  In addition, even  if the  EPA
rule  or a replacement  were to be  reinstated, the EPA  rule or its replacement
would not necessarily affect the potential for liability in actions by either  a
state or a private party under CERCLA or in actions under other federal or state
laws   which  may  impose  liability  on   "owners  or  operators"  but  do  not
 
                                       68
<PAGE>
incorporate the secured-creditor exemption. 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,  nor  the  Sole  Servicer  or  Master  Servicer  makes  any
representations  or  warranties or  assumes any  liability  with respect  to the
absence or effect of hazardous wastes  or hazardous substances on any  Mortgaged
Property  or any  casualty resulting  from the  presence or  effect of hazardous
wastes  or   hazardous   substances.   See   "The   Trust   Estates--   Mortgage
Loans--Representations   and   Warranties"  and   "Servicing  of   the  Mortgage
Loans--Enforcement of Due-on-Sale Clauses;  Realization Upon Defaulted  Mortgage
Loans" above.
 
"DUE-ON-SALE" CLAUSES
 
    The  forms  of note,  mortgage and  deed of  trust relating  to conventional
Mortgage Loans may contain a "due-on-sale" clause permitting acceleration of the
maturity of a loan if  the borrower transfers its  interest in the property.  In
recent  years,  court  decisions  and  legislative  actions  placed  substantial
restrictions on the  right of lenders  to enforce such  clauses in many  states.
However,  effective  October  15,  1982, Congress  enacted  the  Garn-St Germain
Depository Institutions Act of 1982 (the  "Garn Act") which purports to  preempt
state  laws which prohibit the enforcement of "due-on-sale" clauses by providing
among other matters, that  "due-on-sale" clauses in  certain loans (which  loans
may  include the Mortgage Loans)  made after the effective  date of the Garn Act
are enforceable, within certain limitations as set forth in the Garn Act and the
regulations promulgated thereunder. "Due-on-sale" clauses contained in  mortgage
loans  originated by  federal savings and  loan associations  or federal savings
banks are fully  enforceable pursuant  to regulations  of the  Office of  Thrift
Supervision ("OTS"), as successor to the Federal Home Loan Bank Board ("FHLBB"),
which  preempt  state  law  restrictions on  the  enforcement  of  such clauses.
Similarly, "due-on-sale" clauses in  mortgage loans made  by national banks  and
federal   credit  unions  are  now  fully  enforceable  pursuant  to  preemptive
regulations of the  Comptroller of the  Currency and the  National Credit  Union
Administration, respectively.
 
    The  Garn  Act  created  a  limited  exemption  from  its  general  rule  of
enforceability for  "due-on-sale" clauses  in  certain mortgage  loans  ("Window
Period  Loans") which were originated by non-federal lenders and made or assumed
in certain states ("Window Period States")  during the period, prior to  October
15,  1982,  in  which that  state  prohibited the  enforcement  of "due-on-sale"
clauses by constitutional  provision, 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,  a  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, (vi) a transfer into an inter vivos trust in which the borrower is
the beneficiary and which does not
 
                                       69
<PAGE>
relate  to a transfer of  rights of occupancy; and  (vii) other transfers as set
forth in the Garn Act and the  regulations thereunder. The extent of the  effect
of the Garn Act on the average lives and delinquency rates of the Mortgage Loans
cannot be predicted. See "Prepayment and Yield Considerations."
 
APPLICABILITY OF USURY LAWS
 
    Title V of the Depository Institutions Deregulation and Monetary Control Act
of  1980,  enacted  in  March  1980  ("Title  V"),  provides  that  state  usury
limitations shall not apply to certain types of residential first mortgage loans
originated by certain lenders after March 31, 1980. The OTS as successor to  the
FHLBB   is  authorized   to  issue   rules  and   regulations  and   to  publish
interpretations governing implementation of Title V. The statute authorized  any
state  to reimpose interest rate limits by  adopting before April 1, 1983, a law
or constitutional provision which expressly  rejects application of the  federal
law.  Fifteen  states have  adopted laws  reimposing or  reserving the  right to
reimpose interest  rate  limits. In  addition,  even where  Title  V is  not  so
rejected,  any state is  authorized to adopt a  provision limiting certain other
loan charges.
 
    The Seller will represent and warrant in the Pooling and Servicing Agreement
to the Trustee for the benefit of Certificateholders that all Mortgage Loans are
originated in full compliance with applicable state laws, including usury  laws.
See  "The Pooling and  Servicing Agreement--Assignment of  Mortgage Loans to the
Trustee."
 
ENFORCEABILITY OF CERTAIN PROVISIONS
 
    Standard forms  of  note,  mortgage  and deed  of  trust  generally  contain
provisions  obligating the  borrower to  pay a late  charge if  payments are not
timely made  and  in some  circumstances  may  provide for  prepayment  fees  or
penalties  if the obligation is paid prior to maturity. In certain states, there
are or may be specific limitations upon late charges which a lender may  collect
from  a borrower for delinquent payments.  Certain states also limit the amounts
that a lender may collect from a borrower as an additional charge if the loan is
prepaid. Under the Pooling and Servicing Agreement, late charges and  prepayment
fees  (to the extent  permitted by law and  not waived by  the Servicer) will be
retained by the Servicer as additional servicing compensation.
 
    Courts have  imposed general  equitable principles  upon foreclosure.  These
equitable  principles are  generally designed to  relieve the  borrower from the
legal effect of defaults under the loan documents. Examples of judicial remedies
that may be fashioned  include judicial requirements  that the lender  undertake
affirmative  and expensive  actions to determine  the causes  for the borrower's
default and the likelihood that the borrower will be able to reinstate the loan.
In some cases, courts have substituted their judgment for the lender's  judgment
and  have required  lenders to  reinstate loans  or recast  payment schedules to
accommodate borrowers who are suffering from temporary financial disability.  In
some cases, courts have limited the right of lenders to foreclose if the default
under  the mortgage instrument is not monetary,  such as the borrower failing to
adequately maintain the property or the borrower executing a second mortgage  or
deed  of trust  affecting the  property. In other  cases, some  courts have been
faced with  the issue  of  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  general  discussion represents  the  opinion  of Cadwalader,
Wickersham & Taft as to 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  applicable provisions of the Code,
as well  as  regulations  (the  "REMIC Regulations")  promulgated  by  the  U.S.
Department  of the Treasury on December 23, 1992. 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.

    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 that does  not
include    the   Fixed   Retained   Yield.   References   to   a   "Holder"   or
"Certificateholder" in this discussion generally mean the beneficial owner of  a
Certificate.
 
             FEDERAL INCOME TAX CONSEQUENCES FOR REMIC CERTIFICATES
 
GENERAL
 
    With respect to a particular Series of Certificates, an election may be made
to  treat the Trust Estate or one or  more segregated pools of assets therein as
one or more REMICs within the meaning of Code Section 860D. A Trust Estate or  a
portion or portions thereof as to which one or more REMIC elections will be made
will  be  referred  to as  a  "REMIC  Pool." For  purposes  of  this discussion,
Certificates of a Series as to which one or more REMIC elections are made, which
will include all Multi-Class Certificates and may include Standard  Certificates
or  Stripped Certificates or  both, are referred to  as "REMIC Certificates" and
will consist of one or more Classes  of "Regular Certificates" and one Class  of
"Residual Certificates" in the case of each REMIC Pool. Qualification as a REMIC
requires ongoing compliance with certain conditions. With respect to each Series
of REMIC Certificates, Cadwalader, Wickersham & Taft, counsel to the Seller, has
advised  the Seller that  in the firm's  opinion, assuming (i)  the making of an
appropriate election, (ii) compliance with the Pooling and Servicing  Agreement,
and  (iii) compliance with any  changes in the law,  including any amendments to
the Code or  applicable Treasury  regulations thereunder, each  REMIC Pool  will
qualify as a REMIC. In such case, the Regular Certificates will be considered to
be  "regular interests"  in the  REMIC Pool  and generally  will be  treated for
federal income tax purposes as if  they were newly originated debt  instruments,
and  the Residual Certificates will be  considered to be "residual interests" in
the REMIC Pool. The Prospectus Supplement  for each Series of Certificates  will
indicate  whether one or more REMIC elections  with respect to the related Trust
Estate will be made, in which event references to "REMIC" or "REMIC Pool" herein
shall be deemed to refer to each such REMIC Pool.
 
STATUS OF REMIC CERTIFICATES
 
    REMIC Certificates held by a mutual savings bank or a domestic building  and
loan  association will  constitute "qualifying  real property  loans" within the
meaning of Code Section 593(d)(1) in the same proportion that the assets of  the
REMIC  Pool would be so treated. REMIC  Certificates held by a domestic building
and loan association will constitute "a regular or residual interest in a REMIC"
within the meaning  of Code  Section 7701(a)(19)(C)(xi) in  the same  proportion
that  the assets of  the REMIC Pool  would be treated  as "loans...secured by an
interest in real property" within the meaning of Code Section  7701(a)(19)(C)(v)
or  as other assets described in Code Section 7701(a)(19)(C). REMIC Certificates
held by a  real estate  investment trust  will constitute  "real estate  assets"
within  the meaning  of Code Section  856(c)(5)(A), and interest  on the Regular
Certificates and income with respect to Residual 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
 
                                       71
<PAGE>
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, such as  lower-tier
regular  interests in a  tiered REMIC. The REMIC  Regulations 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  rate, inverse  variable rate  or difference
between two fixed or qualified  variable rates 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
 
                                       72
<PAGE>
dependent on the absence of defaults or delinquencies on qualified mortgages  or
permitted  investments,  lower  than reasonably  expected  returns  on permitted
investments, unanticipated expenses  incurred by  the REMIC  Pool or  prepayment
interest  shortfalls.  Accordingly, the  Regular Certificates  of a  Series will
constitute  one  or  more  classes  of  regular  interests,  and  the   Residual
Certificates  with  respect to  that Series  will constitute  a single  class of
residual interests on which distributions are made pro rata.
 
    If an entity, such as  the REMIC Pool, fails to  comply with one or more  of
the  ongoing requirements of the Code for  REMIC status during any taxable year,
the Code provides that the entity will not  be treated as a REMIC for such  year
and  thereafter. In  this event,  an entity  with multiple  classes of ownership
interests may be  treated as  a separate  association taxable  as a  corporation
under  Treasury  regulations, and  the Regular  Certificates  may be  treated as
equity interests therein. The Code, however, authorizes the Treasury  Department
to  issue regulations that address situations where  failure to meet one or more
of the requirements for REMIC status occurs inadvertently and in good faith, and
disqualification of  the  REMIC  Pool  would  occur  absent  regulatory  relief.
Investors  should be aware, however, that the Conference Committee Report to the
Tax Reform  Act of  1986  (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  temporary  and  final   Treasury
regulations  issued on  February 2,  1994 (the  "OID Regulations")  and proposed
Treasury  regulations  issued   on  December   16,  1994   (the  "Proposed   OID
Regulations")  under Code Sections 1271 through 1273 and 1275 and in part on the
provisions of the 1986 Act. Regular Certificateholders should be aware, however,
that the OID  Regulations and  the Proposed  OID Regulations  do not  adequately
address  certain issues relevant  to prepayable securities,  such as the Regular
Certificates. To the extent such issues  are not addressed in such  regulations,
the  Seller  intends  to  apply  the  methodology  described  in  the Conference
Committee Report to the 1986 Act. No assurance can be provided that the Internal
Revenue Service  will not  take a  different position  as to  those matters  not
currently  addressed by  the OID Regulations  and the  Proposed OID Regulations.
Moreover, the OID Regulations include  an anti-abuse rule allowing the  Internal
Revenue  Service to apply or depart from  the OID Regulations where necessary or
appropriate to  ensure  a reasonable  tax  result  in light  of  the  applicable
statutory provisions. A tax result will not be considered unreasonable under the
anti-abuse rule in the absence of a substantial effect on the present value of a
taxpayer's  tax  liability.  Investors  are advised  to  consult  their  own tax
advisors as to the  discussion herein and the  appropriate method for  reporting
interest and original issue discount with respect to the Regular Certificates.
 
    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 "Non-Pro  Rata 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  Class  of Regular  Certificates  offered
pursuant  to this Prospectus generally is the first price at which a substantial
amount of such Class is sold to  the public (excluding bond houses, brokers  and
underwriters). Although unclear under the OID Regulations, the Seller intends to
treat  the issue price of a Class as to which there is no substantial sale as of
the issue  date or  that is  retained by  the Seller  as the  fair market  value
 
                                       73
<PAGE>
of  that Class as  of the issue date.  The issue price  of a Regular Certificate
also includes  any  amount paid  by  an initial  Regular  Certificateholder  for
accrued interest that relates to a period prior to the issue date of the Regular
Certificate,  unless the Regular Certificateholder  elects on its federal income
tax return to exclude such amount from the issue price and to recover it on  the
first  Distribution Date. 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 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.  Because  there is  no penalty  or  default remedy  in the  case of
nonpayment of interest  with respect to  a Regular Certificate,  it is  possible
that  no  interest on  any  Class of  Regular  Certificates will  be  treated as
qualified stated interest. However,  except as provided  in the following  three
sentences  or in  the applicable  Prospectus Supplement,  because the underlying
Mortgage Loans provide for remedies in the event of default, the Seller  intends
to  treat interest with respect to  the Regular Certificates as qualified stated
interest. Distributions of interest  on a Compound  Interest Certificate, or  on
other  Regular Certificates with respect to which deferred interest will accrue,
will not  constitute  qualified  stated  interest,  in  which  case  the  stated
redemption   price  at  maturity  of  such  Regular  Certificates  includes  all
distributions of interest  as well  as principal thereon.  Likewise, the  Seller
intends  to  treat  an interest-only  Class  or  a Class  on  which  interest is
substantially  disproportionate   to   its   principal   amount   (a   so-called
"super-premium"  Class)  as  having  no  qualified  stated  interest.  Where the
interval between the  issue date and  the first Distribution  Date on a  Regular
Certificate  is shorter than the interval between subsequent Distribution Dates,
the interest attributable to the additional days will be included in the  stated
redemption price at maturity.
 
    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. The Conference Committee Report to  the 1986 Act provides that  the
schedule  of  such distributions  should be  determined  in accordance  with the
assumed rate of prepayment of  the Mortgage Loans (the "Prepayment  Assumption")
and  the  anticipated  reinvestment  rate,  if  any,  relating  to  the  Regular
Certificates. 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 original  issue discount 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  OID Regulations,  however,
Regular  Certificateholders may  elect to accrue  all DE  MINIMIS original issue
discount as well as market discount and market premium, under the constant yield
method. See "Election to Treat All Interest Under the Constant Yield Method."
 
    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 the  day before 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  day
before  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  Non-Pro Rata  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
 
                                       74
<PAGE>
period, and (iii) the  Prepayment Assumption. For  these purposes, the  adjusted
issue  price of  a Regular  Certificate at the  beginning of  any accrual period
equals the issue price  of the Regular Certificate,  increased by the  aggregate
amount  of original issue discount with  respect to the Regular Certificate that
accrued in all prior accrual periods and reduced by the amount of  distributions
included  in the Regular Certificate's stated  redemption price at maturity that
were made on the Regular Certificate  in such prior periods. The original  issue
discount  accruing during any  accrual period (as  determined in this paragraph)
will then be divided by the number of days in the period to determine the  daily
portion  of original issue discount for each  day in the period. With respect to
an initial accrual period shorter than a full accrual period, the daily portions
of original  issue  discount must  be  determined according  to  an  appropriate
allocation under 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.  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 Non-Pro Rata  Certificate, the Seller intends to determine
the yield to  maturity of such  Certificate 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 Non-Pro Rata  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  Non-Pro Rata 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 Non-Pro  Rata 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. The Seller  believes that  the
foregoing  treatment is consistent  with the "pro rata  prepayment" rules of the
OID Regulations,  but  with the  rate  of  accrual of  original  issue  discount
determined  based  on  the  Prepayment  Assumption for  the  Class  as  a whole.
Investors are advised to consult their tax advisors as to this treatment.
 
  ACQUISITION PREMIUM
 
    A purchaser of a  Regular Certificate at a  price greater than its  adjusted
issue  price  but less  than its  stated  redemption price  at maturity  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. Alternatively,  such
a subsequent purchaser may elect to treat all such acquisition premium under the
constant  yield method, as described below  under the heading "Election to Treat
All Interest Under the Constant Yield Method."
 
  VARIABLE RATE REGULAR CERTIFICATES
 
    Regular Certificates  may provide  for interest  based on  a variable  rate.
Under the OID Regulations, interest is treated as payable at a variable rate if,
generally, (i) the issue price does not exceed the original principal balance by
more  than a specified amount  and (ii) the interest  compounds or is payable at
least annually at current values of (a) one or more "qualified floating  rates,"
(b)  a single fixed rate and one or  more qualified floating rates, (c) a single
"objective rate," or (d) a single fixed rate and a single objective rate that is
a "qualified inverse  floating rate." A  floating rate is  a qualified  floating
rate   if  variations  in  the  rate  can  reasonably  be  expected  to  measure
contemporaneous variations in the cost of newly borrowed funds, where such  rate
is subject to a multiple of not less than zero nor more than 1.35. Such rate may
also  be increased or decreased by  a fixed spread or subject  to a fixed cap or
floor, or a cap or floor that is not reasonably expected as of the issue date to
affect the yield of the instrument  significantly. An objective rate includes  a
rate  determined using a single  fixed formula and that is  based on one or more
qualified floating rates or the yield or changes in the price of actively traded
personal property. The Proposed OID  Regulations would expand the definition  of
 
                                       75
<PAGE>
objective  rate to include any rate (other  than a qualified floating rate) that
is determined  using a  single fixed  formula  and that  is based  on  objective
financial  or economic  information, provided that  such information  is not (i)
within the  control of  the issuer  or a  related party  or (ii)  unique to  the
circumstances  of the  issuer or a  related party. A  qualified inverse floating
rate is  a rate  equal to  a fixed  rate minus  a qualified  floating rate  that
inversely  reflects  contemporaneous variations  in the  cost of  newly borrowed
funds; an inverse floating  rate that is not  a qualified inverse floating  rate
may  nevertheless be an objective  rate. A Class of  Regular Certificates may be
issued under  this Prospectus  that does  not  have a  variable rate  under  the
foregoing  rules, for example,  a Class that bears  different rates at different
times  during  the  period  it  is  outstanding  such  that  it  is   considered
significantly  "front-loaded"  or "back-loaded"  within the  meaning of  the OID
Regulations. It  is  possible  that such  a  Class  may be  considered  to  bear
"contingent interest" within the meaning of the OID Regulations and the Proposed
OID  Regulations. The Proposed OID Regulations,  as they relate to the treatment
of  contingent  interest,  are  by   their  terms  not  applicable  to   Regular
Certificates.  However, if  final regulations  dealing with  contingent interest
with respect to Regular Certificates apply  the same principles as the  Proposed
OID  Regulations,  such  regulations  may lead  to  different  timing  of income
inclusion than  would  be  the  case under  the  OID  Regulations.  Furthermore,
application of such principles could lead to the characterization of gain on the
sale  of contingent interest Regular  Certificates as ordinary income. Investors
should consult their  tax advisors  regarding the appropriate  treatment of  any
Regular  Certificate that does not pay interest at a fixed rate or variable rate
as described in this paragraph.
 
    Under the REMIC Regulations, a Regular  Certificate (i) bearing a rate  that
qualifies  as a variable rate under the  OID Regulations that is tied to current
values of a  variable rate (or  the highest, lowest  or average of  two or  more
variable  rates, including a rate  based on the average cost  of funds of one or
more financial institutions), or a positive or negative multiple of such a  rate
(plus  or  minus a  specified  number of  basis  points), or  that  represents a
weighted average of rates on some or all of the Mortgage Loans, 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, and a different variable rate or fixed rate for other  periods,
qualifies  as  a  regular interest  in  a REMIC.  Accordingly,  unless otherwise
indicated in the applicable Prospectus  Supplement, the Seller intends to  treat
Regular  Certificates that qualify  as regular interests under  this rule in the
same manner as obligations bearing a  variable rate for original issue  discount
reporting purposes.
 
    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 generally to be determined by assuming that interest
will be payable for  the life of  the Regular Certificate  based on the  initial
rate  (or, if  different, the value  of the  applicable variable rate  as of the
pricing date)  for  the  relevant  Class.  Unless  otherwise  specified  in  the
applicable  Prospectus  Supplement, the  Seller intends  to treat  such variable
interest as  qualified  stated interest,  other  than variable  interest  on  an
interest-only  or super-premium  Class, which  will be  treated as non-qualified
stated interest includible in the stated redemption price at maturity.  Ordinary
income reportable for any period will be adjusted based on subsequent changes in
the applicable interest rate index.
 
    Although  unclear under the  OID Regulations, unless  otherwise specified in
the applicable  Prospectus  Supplement,  the Seller  intends  to  treat  Regular
Certificates  bearing an  interest rate  that is a  weighted average  of the net
interest rates on Mortgage Loans as having qualified stated interest, except  to
the extent that initial "teaser" rates cause sufficiently "back-loaded" interest
to  create  more than  DE MINIMIS  original  issue discount.  The yield  on such
Regular Certificates for purposes of accruing original issue discount will be  a
hypothetical  fixed rate  based on the  fixed rates,  in the case  of fixed rate
Mortgage Loans, and initial "teaser rates"  followed by fully indexed rates,  in
the  case of  adjustable rate  Mortgage Loans.  In the  case of  adjustable rate
Mortgage Loans, the applicable  index used to compute  interest on the  Mortgage
Loans  in effect on the pricing date (or possibly the issue 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. 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
Certificates.
 
  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  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
 
                                       76
<PAGE>
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 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.  See "Election to Treat All Interest
Under the Constant Yield Method" below regarding an alternative manner in  which
such election may be deemed to be made.
 
    By analogy to the 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  third  paragraph  under
"Original Issue Discount") remaining after the date of purchase. It appears that
DE  MINIMIS market discount would be reported  in a manner similar to DE MINIMIS
original  issue  discount.  See   "Original  Issue  Discount"  above.   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 the constant yield method.
 
  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  yield  method.  Such  election  will  apply  to  all  debt
obligations acquired by the Regular Certificateholder at a premium held in  that
taxable  year or thereafter, unless revoked  with the permission of the Internal
Revenue Service. The  Conference Committee Report  to the 1986  Act indicates  a
Congressional  intent that the  same rules that  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. See "Election to
Treat  All  Interest  Under  the  Constant  Yield  Method"  below  regarding  an
alternative  manner in which the  Code Section 171 election  may be deemed to be
made.
 
  ELECTION TO TREAT ALL INTEREST UNDER THE CONSTANT YIELD METHOD
 
    A holder of a  debt instrument such  as a Regular  Certificate may elect  to
treat  all  interest that  accrues on  the instrument  using the  constant yield
method, with none of  the interest being treated  as qualified stated  interest.
For  purposes of applying the constant yield method to a debt instrument subject
to such an  election, (i)  "interest" includes stated  interest, original  issue
discount,  DE MINIMIS  original issue discount,  market discount  and DE MINIMIS
market discount,  as adjusted  by any  amortizable bond  premium or  acquisition
premium and (ii) the debt instrument is treated
 
                                       77
<PAGE>
as  if the instrument were issued on the holder's acquisition date in the amount
of the  holder's adjusted  basis immediately  after acquisition.  It is  unclear
whether,  for this purpose, the initial  Prepayment Assumption would continue to
apply or  if  a  new prepayment  assumption  as  of the  date  of  the  holder's
acquisition  would apply.  A holder  generally may make  such an  election on an
instrument by instrument  basis or  for a class  or group  of debt  instruments.
However,  if the holder makes such an election with respect to a debt instrument
with amortizable bond premium or with  market discount, the holder is deemed  to
have made elections to amortize bond premium or to report market discount income
currently  as it accrues under the  constant yield method, respectively, for all
premium bonds held or market discount bonds  acquired by the holder in the  same
taxable  year or thereafter. The election is made on the holder's federal income
tax return  for  the year  in  which the  debt  instrument is  acquired  and  is
irrevocable  except with the approval of the Internal Revenue Service. Investors
should consult their own tax advisors regarding the advisability of making  such
an election.
 
  TREATMENT OF LOSSES
 
    Regular Certificateholders will be required to report income with respect to
Regular  Certificates on the accrual method of accounting, without giving effect
to  delays  or   reductions  in  distributions   attributable  to  defaults   or
delinquencies  on the Mortgage Loans, except to the extent it can be established
that such  losses  are  uncollectible.  Accordingly, the  holder  of  a  Regular
Certificate,  particularly a Subordinated  Certificate, may have  income, or may
incur a diminution in cash flow as a result of a default or delinquency, but may
not be  able to  take a  deduction (subject  to the  discussion below)  for  the
corresponding  loss until a  subsequent taxable year.  In this regard, investors
are cautioned that while they may  generally cease to accrue interest income  if
it  reasonably appears  that the  interest will  be uncollectible,  the Internal
Revenue Service may take the position that original issue discount must continue
to be accrued  in spite  of its uncollectibility  until the  debt instrument  is
disposed of in a taxable transaction or becomes worthless in accordance with the
rules of Code Section 166.
 
    To  the  extent  the rules  of  Code  Section 166  regarding  bad  debts are
applicable, it appears that Regular Certificateholders that are corporations  or
that  otherwise  hold the  Regular Certificates  in connection  with a  trade or
business should in general be  allowed to deduct as  an ordinary loss such  loss
with  respect to principal sustained  during the taxable year  on account of any
such Regular Certificates becoming wholly  or partially worthless, and that,  in
general,  Regular Certificateholders that  are not corporations  and do not hold
the Regular  Certificates in  connection  with a  trade  or business  should  be
allowed  to deduct as a  loss, which may be a  short-term capital loss, any loss
sustained during the taxable year  on account of a  portion of any such  Regular
Certificates  becoming wholly  worthless. Although the  matter is  not free from
doubt, such non-corporate  Regular Certificateholders  should be  allowed a  bad
debt   deduction  at  such  time  as  the  principal  balance  of  such  Regular
Certificates is reduced to reflect losses resulting from any liquidated Mortgage
Loans. The Internal Revenue Service, however, could take the position that  such
non-corporate  holders  will be  allowed a  bad debt  deduction to  reflect such
losses only after all the Mortgage Loans remaining in the Trust Estate have been
liquidated or the applicable  Class of Regular  Certificates has been  otherwise
retired.  The  Internal Revenue  Service could  also assert  that losses  on the
Regular Certificates are deductible  based on some other  method that may  defer
such  deductions for all holders, such as reducing future cash flow for purposes
of computing  original issue  discount. This  may have  the effect  of  creating
"negative" original issue discount which would be deductible only against future
positive  original issue  discount or otherwise  upon termination  of the Class.
Regular Certificateholders are urged to consult their own tax advisors regarding
the appropriate timing, amount and character of any loss sustained with  respect
to  such Regular Certificates. While  losses attributable to interest previously
reported as income should be deductible as ordinary losses by both corporate and
non-corporate holders, the Internal Revenue  Service may take the position  that
losses  attributable to accrued original issue  discount may only be deducted as
short-term capital losses  by non-corporate holders  not engaged in  a trade  or
business.  Special loss rules  are applicable to  banks and thrift institutions,
including rules regarding reserves for bad debts. Such taxpayers are advised  to
consult  their  tax  advisors  regarding  the  treatment  of  losses  on Regular
Certificates.
 
  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,  by  any  amortized  premium  and  by any
recognized losses.

    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  (i) if a  Regular Certificate is held  as part of  a
"conversion transaction" as defined in Code Section 1258(c), up to the amount of
interest  that  would  have  accrued  on  the  Regular  Certificateholder's  net
investment in the conversion transaction  at 120% of the appropriate  applicable
Federal  rate under  Code Section  1274(d) in  effect at  the time  the taxpayer
entered into the  transaction minus  any amount previously  treated as  ordinary
income  with respect to any prior disposition  of property that was held as part
of such transaction, (ii) in the case of a non-corporate taxpayer, to the extent
such taxpayer has  made an  election under Code  Section 163(d)(4)  to have  net
capital  gains taxed as investment income at  ordinary income rates, or (iii) to
the extent that such gain does not exceed the excess, if any, of (a) the  amount
that  would have been includible in the gross  income of the holder if its yield
on such Regular Certificate were 110% of  the applicable Federal rate as of  the
date of purchase, over (b) the amount of income actually includible in the gross
income  of such  holder with respect  to such 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). Pursuant to the Revenue Reconciliation Act of 1993, capital
gains of certain non-corporate taxpayers are subject to a lower maximum tax rate
than ordinary income of such taxpayers. The maximum tax rate for corporations is
the same with respect to both ordinary income and capital gains.
 
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  limitations on  deductibility of investment  interest expense  and
expenses  for the production of income do not  apply, (ii) all bad loans will be
deductible as business bad debts, and (iii) the limitation on the  deductibility
of  interest and  expenses related  to tax-exempt  income will  apply. The REMIC
Pool's gross  income  includes interest,  original  issue discount  income,  and
market  discount income, if any, on  the Mortgage Loans, reduced by amortization
of any premium  on the Mortgage  Loans, plus income  from amortization of  issue
premium,  if any,  on the Regular  Certificates, plus income  on reinvestment of
cash flows and reserve assets, plus any cancellation of indebtedness income upon
allocation of  realized losses  to the  Regular Certificates.  The REMIC  Pool's
deductions  include interest and original issue  discount expense on the Regular
Certificates,  servicing  fees  on  the  Mortgage  Loans,  other  administrative
expenses  of  the REMIC  Pool and  realized  losses on  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)  or
income  from amortization of  issue premium 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  or are issued at  a premium. If taxable  income attributable to such a
mismatching is realized, in general, losses  would be allowed in later years  as
distributions  on the later  maturing Classes of  Regular Certificates are made.
Taxable income
 
                                       79
<PAGE>
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 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
 
    Although  the  Seller  intends  to  compute  REMIC  income  and  expense  in
accordance with the Code and  applicable regulations, the authorities  regarding
the  determination  of  specific items  of  income  and expense  are  subject to
differing interpretations. The Seller makes no representation as to the specific
method that it will use for reporting income with respect to the Mortgage  Loans
and  expenses with  respect to  the Regular  Certificates and  different methods
could result in different timing of reporting  of taxable income or net loss  to
Residual Holders or differences in capital gain versus ordinary income.
 
                                       80
<PAGE>
    ORIGINAL ISSUE DISCOUNT AND PREMIUM.  Generally, the REMIC Pool's deductions
for  original issue discount and income  from amortization of issue premium 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,  and
"--Premium."
 
    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.  The accrued portion of  such
market discount would be recognized currently as an item of ordinary income in a
manner  similar  to original  issue discount.  Market discount  income generally
should  accrue  in  the  manner  described  above  under  "Taxation  of  Regular
Certificates--Market Discount."
 
    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 the constant yield 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
 
    Except in the case of certain thrift institutions, a portion (or 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. Accordingly, the portion of the REMIC Pool's taxable income that will be
treated as excess  inclusions will be  a larger  portion of such  income as  the
adjusted issue price of the Residual Certificates diminishes.
 
    The  portion of a  Residual Holder's REMIC taxable  income consisting of the
excess inclusions generally may not be offset by other deductions, including net
operating loss carryforwards, on such Residual Holder's return. Further, if  the
Residual  Holder is  an organization  subject to  the tax  on unrelated business
income imposed by Code Section 511, the Residual Holder's excess inclusions will
be treated as  unrelated business  taxable income  of such  Residual Holder  for
purposes  of Code Section 511.  In addition, REMIC taxable  income is subject to
30% withholding tax with respect to certain persons who are not U.S. Persons (as
defined  below  under   "Tax-Related  Restrictions  on   Transfer  of   Residual
Certificates--Foreign  Investors"),  and  the  portion  thereof  attributable to
excess inclusions is not eligible for  any reduction in the rate of  withholding
tax   (by   treaty   or   otherwise).   See   "Taxation   of   Certain   Foreign
Investors--Residual Certificates" below.  Finally, 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
 
                                       81
<PAGE>
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
Certificate and the transferor pays income tax at the highest corporate rate  on
the excess inclusion for the period the Residual Certificate is actually held by
the Disqualified Organization.
 
    In  addition,  if  a "Pass-Through  Entity"  (as defined  below)  has excess
inclusion income with respect  to a Residual Certificate  during a taxable  year
and  a Disqualified Organization is  the record holder of  an equity interest in
such entity, then a tax  is imposed on such entity  equal to the product of  (i)
the  amount  of excess  inclusions that  are  allocable to  the interest  in the
Pass-Through Entity during the period such interest is held by such Disqualified
Organization, and (ii) the highest  marginal federal corporate income tax  rate.
Such  tax would be deductible from the ordinary gross income of the Pass-Through
Entity for the  taxable year. The  Pass-Through Entity would  not be liable  for
such  tax if it has received an affidavit from such record holder that it is not
a Disqualified  Organization or  stating such  holder's taxpayer  identification
number  and, during the period such person  is the record holder of the Residual
Certificate, the Pass-Through Entity  does not have  actual knowledge that  such
affidavit is false.
 
    For these purposes, (i) "Disqualified Organization" means the United States,
any  state  or  political  subdivision  thereof,  any  foreign  government,  any
international  organization,  any  agency  or  instrumentality  of  any  of  the
foregoing  (provided, that such term does  not include an instrumentality if all
of   its   activities   are   subject   to   tax   and   a   majority   of   its
 
                                       82
<PAGE>
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 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
 
                                       83
<PAGE>
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.
 
    Any gain on the sale of a  Residual Certificate will be treated as  ordinary
income  (i)  if  a  Residual  Certificate  is  held  as  part  of  a "conversion
transaction" as defined in  Code Section 1258(c), up  to the amount of  interest
that  would have accrued  on the Residual  Certificateholder's net investment in
the conversion transaction at 120% of the appropriate applicable Federal rate in
effect at the time  the taxpayer entered into  the transaction minus any  amount
previously  treated as ordinary income with  respect to any prior disposition of
property that was held as a  part of such transaction or  (ii) in the case of  a
non-corporate  taxpayer, to the extent such  taxpayer has made an election under
Code Section 163(d)(4) to have net  capital gains taxed as investment income  at
ordinary  income rates. In addition, gain or  loss recognized from the sale of a
Residual Certificate by certain banks or thrift institutions will be treated  as
ordinary income or loss pursuant to Code Section 582(c).
 
    The  Conference Committee  Report to the  1986 Act provides  that, except as
provided in Treasury regulations yet to be  issued, the wash sale rules of  Code
Section  1091  will apply  to dispositions  of  Residual Certificates  where the
seller of  the Residual  Certificate,  during the  period beginning  six  months
before the sale or disposition of the Residual Certificate and ending six months
after  such sale or disposition, acquires  (or enters into any other transaction
that results in the application of  Code Section 1091) any residual interest  in
any  REMIC or  any interest in  a "taxable  mortgage pool" (such  as a non-REMIC
owner trust) that is economically comparable to a Residual Certificate.
 
  MARK TO MARKET REGULATIONS
 
    Prospective purchasers of the Residual Certificates should be aware that  on
January 3, 1995, the Internal Revenue Service released proposed regulations (the
"Proposed  Mark to Market  Regulations") under Code Section  475 relating to the
requirement that a securities dealer mark to market securities held for sale  to
customers.  This  mark-to-market  requirement  applies to  all  securities  of a
dealer, except  to the  extent that  the dealer  has specifically  identified  a
security as held for investment. The Proposed Mark to Market Regulations provide
that, for purposes of this mark-to-market requirement, a Residual Certificate is
not  treated as a  security and thus may  not be marked  to market. The Proposed
Mark to Market  Regulations apply to  all Residual Certificates  acquired on  or
after January 4, 1995.
 
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
 
                                       84
<PAGE>
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  not be subject to the prohibited  transaction
rules  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 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  Sole  Servicer  or  Master  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 Sole Servicer  or Master 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
 
                                       85
<PAGE>
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) (subject  to adjustment for inflation), 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.  Unless   indicated
otherwise  in the  applicable Prospectus Supplement,  all such  expenses will be
allocable to the Residual Certificates. 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 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  generally should  be 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--
 
                                       86
<PAGE>
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 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
 
                                       87
<PAGE>
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  its
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  its 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 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" to such extent 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 clauses  1,  2  and  3  of  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."
 
                                       88
<PAGE>
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) or as "real estate assets"  under
Code  Section 856(c)(5)(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.
 
    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  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.
Unless  indicated  otherwise  in   the  applicable  Prospectus  Supplement,   no
prepayment  assumption will  be assumed for  purposes of  such accrual. 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
Regular Certificates--Market Discount," except that the ratable accrual  methods
described therein will not apply. Rather, the holder will accrue market discount
pro  rata over the life of the  Mortgage Loans, unless the constant yield method
is elected. Unless indicated otherwise in the applicable Prospectus  Supplement,
no prepayment assumption will be assumed for purposes of such accrual.
 
  RECHARACTERIZATION OF SERVICING FEES
 
    If  the servicing fees paid  to a Servicer were  deemed to exceed reasonable
servicing compensation, the amount of such excess would represent neither income
nor  a  deduction  to   Certificateholders.  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
 
                                       89
<PAGE>
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
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.
 
  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  generally would  be capital  gain or  loss if  the Standard
Certificate was held as a capital asset. However, gain on the sale of a Standard
Certificate will be treated as ordinary income (i) if a Standard Certificate  is
held  as part of a "conversion transaction"  as defined in Code Section 1258(c),
up  to  the  amount  of  interest  that  would  have  accrued  on  the  Standard
Certificateholder's  net investment in the conversion transaction at 120% of the
appropriate applicable Federal rate in effect  at the time the taxpayer  entered
into the transaction minus any amount previously treated as ordinary income with
respect  to any prior  disposition of property that  was held as  a part of such
transaction or (ii) in the case of a non-corporate taxpayer, to the extent  such
taxpayer  has made an election under Code  Section 163(d)(4) to have net capital
gains taxed  as investment  income at  ordinary income  rates. Pursuant  to  the
Revenue  Reconciliation  Act  of  1993  capital  gains  of  certain noncorporate
taxpayers are subject to a lower maximum  tax rate than ordinary income of  such
taxpayers.  The maximum tax  rate for corporations  is the same  with respect to
both ordinary income and capital gains.
 
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
 
                                       90
<PAGE>
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.
 
    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  a Servicer,  to  the extent  that such  fees represent
reasonable compensation for  services rendered. See  the discussion above  under
"Standard Certificates--Recharacterization of Servicing Fees." Although not free
from  doubt,  for  purposes  of reporting  to  Stripped  Certificateholders, the
servicing fees will be allocated to  the Stripped Certificates in proportion  to
the  respective entitlements  to distributions  of each  Class (or  Subclass) of
Stripped Certificates  for  the related  period  or  periods. 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
OID  Regulations.  Although it  is possible  that  computations with  respect to
Stripped Certificates could  be made in  one of the  ways described below  under
"Taxation of Stripped Certificates--Possible Alternative Characterizations," the
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 purchased 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 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, assuming that a prepayment assumption is employed in such computation.
 
  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  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
 
                                       91
<PAGE>
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  OID Regulations  and  the
amendments  to the original issue discount sections of the Code made by the 1986
Act, 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 a loss (which may be a capital loss) equal  to
such portion of unrecoverable basis.
 
    As  an alternative to the method described  above, the fact that some or all
of the interest payments with respect  to the Stripped Certificates will not  be
made  if the Mortgage  Loans are prepaid  could lead to  the interpretation that
such  interest  payments  are  "contingent"  within  the  meaning  of  the   OID
Regulations  and the Proposed OID Regulations.  The Proposed OID Regulations, as
they relate to  the treatment  of contingent interest,  are by  their terms  not
applicable  to prepayable securities such as the Stripped Certificates. However,
if final  regulations  dealing with  contingent  interest with  respect  to  the
Stripped Certificates apply the same principles as the Proposed OID Regulations,
such  regulations may lead to different timing of income inclusion than would be
the case under the OID Regulations. Furthermore, application of such  principles
could  lead to the characterization  of gain on the  sale of contingent interest
Stripped Certificates as  ordinary income.  Investors should  consult their  tax
advisors regarding the appropriate tax treatment of 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
 
                                       92
<PAGE>
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 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
that  purchased  at the  issue price.  In  particular, in  the case  of Stripped
Certificates, unless provided otherwise in the applicable Prospectus Supplement,
such reporting will  be based upon  a representative initial  offering price  of
each  Class of Stripped  Certificates. 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
 
                                       93
<PAGE>
such  Plans. The  following is  a general  discussion of  such requirements, and
certain  applicable  exceptions  to  and  administrative  exemptions  from  such
requirements.  For purposes of this discussion,  a person investing on behalf of
an individual retirement account established  under Code Section 408 (an  "IRA")
is regarded as a fiduciary and the IRA as a Plan.
 
    Before purchasing any Certificates, a Plan fiduciary should consult with its
counsel  and determine  whether there  exists any  prohibition to  such purchase
under the requirements of ERISA, whether prohibited transaction exemptions  such
as  PTE 83-1  or any  individual administrative  exemption (as  described below)
applies, including whether the appropriate conditions set forth therein would be
met, or whether  any statutory prohibited  transaction exemption is  applicable,
and further should consult the applicable Prospectus Supplement relating to such
Series of Certificates.
 
CERTAIN REQUIREMENTS UNDER ERISA
 
    GENERAL.   In  accordance with  ERISA's general  fiduciary standards, before
investing in a Certificate a Plan fiduciary should determine whether to do so is
permitted under the governing Plan instruments  and is appropriate for the  Plan
in view of its overall investment policy and the composition and diversification
of  its  portfolio.  A  Plan  fiduciary  should  especially  consider  the ERISA
requirement of investment  prudence and  the sensitivity  of the  return on  the
Certificates  to the rate of principal repayments (including prepayments) on the
Mortgage Loans, as discussed in "Prepayment and Yield Considerations" herein.
 
    PARTIES IN INTEREST/DISQUALIFIED  PERSONS.  Other  provisions of ERISA  (and
corresponding  provisions of  the Code) prohibit  certain transactions involving
the assets of a Plan and persons who have certain specified relationships to the
Plan  (so-called  "parties  in  interest"   within  the  meaning  of  ERISA   or
"disqualified  persons" within  the meaning of  the Code). The  Seller, the Sole
Servicer or Master 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 (including
assets that may be held in  an insurance company's separate or general  accounts
where  assets in such accounts may be  deemed Plan assets for purposes of ERISA)
are used to purchase a Certificate if, with respect to such assets, the  Seller,
the  Sole Servicer  or Master  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,
 
                                       94
<PAGE>
IRAs, and employee benefit plans not subject to ERISA (for example, governmental
plans),  but this exception  is tested immediately after  each acquisition of an
equity interest in the entity whether upon initial issuance or in the  secondary
market.
 
ADMINISTRATIVE EXEMPTIONS
 
    INDIVIDUAL    ADMINISTRATIVE   EXEMPTIONS.       Several   underwriters   of
mortgage-backed securities  have  applied  for  and  obtained  ERISA  prohibited
transaction  exemptions (each, an  "Underwriter's Exemption") which  are in some
respects broader  than Prohibited  Transaction Class  Exemption 83-1  (described
below).  Such  exemptions can  only apply  to mortgage-backed  securities which,
among other  conditions, are  sold in  an offering  with respect  to which  such
underwriter  serves as the  sole or a  managing underwriter, or  as a selling or
placement agent. If  such an Underwriter's  Exemption might be  applicable to  a
Series  of Certificates,  the related Prospectus  Supplement will  refer to such
possibility.
 
    Among the conditions that must  be satisfied for an Underwriter's  Exemption
to apply are the following:
 
        (1) The acquisition of Certificates by a Plan is on terms (including the
    price  for the Certificates) that  are at least as  favorable to the Plan as
    they would be in an arm's length transaction with an unrelated party;
 
        (2) The rights and interests  evidenced by Certificates acquired by  the
    Plan  are not  subordinated to the  rights and interests  evidenced by other
    Certificates of the Trust Estate;
 
        (3) The Certificates acquired by the Plan have received a rating at  the
    time  of such acquisition  that is one  of the three  highest generic rating
    categories from either Standard & Poors ("S&P"), Moody's Investors  Service,
    Inc. ("Moody's"), Duff & Phelps Credit Rating Co. ("DCR") or Fitch Investors
    Service, L.P. ("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
       DCR 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
 
                                       95
<PAGE>
and  at least  fifty percent of  the aggregate  interest in the  Trust Estate is
acquired by persons independent of the Restricted Group (as defined below); (ii)
such fiduciary (or its affiliate) is an obligor with respect to five percent  or
less  of the  fair market  value of  the Mortgage  Loans contained  in the Trust
Estate; (iii) the Plan's investment in Certificates of any Class does not exceed
twenty-five percent of all of the Certificates of that Class outstanding at  the
time  of the acquisition and (iv) immediately after the acquisition no more than
twenty-five percent of the assets of the Plan with respect to which such  person
is  a fiduciary are invested in Certificates  representing an interest in one or
more trusts containing assets sold or served by the same entity.
 
    An Underwriter's Exemption does not apply to Plans sponsored by the  Seller,
the  underwriter specified in the applicable Prospectus Supplement, the Trustee,
the Servicer, any obligor with respect  to Mortgage Loans included in the  Trust
Estate  constituting  more  than  five  percent  of  the  aggregate  unamortized
principal balance of the assets  in the Trust Estate,  or any affiliate of  such
parties (the "Restricted Group").
 
    PTE   83-1.    Prohibited  Transaction  Class  Exemption  83-1  for  Certain
Transactions Involving  Mortgage Pool  Investment  Trusts ("PTE  83-1")  permits
certain  transactions  involving the  creation,  maintenance and  termination of
certain residential mortgage pools  and the acquisition  and holding of  certain
residential mortgage pool pass-through certificates by Plans, whether or not the
Plan's  assets would be deemed to include an ownership interest in the mortgages
in such mortgage pools, and whether or not such transactions would otherwise  be
prohibited under ERISA.
 
    The  term "mortgage pool pass-through certificate" is defined in PTE 83-1 as
"a certificate  representing a  beneficial undivided  fractional interest  in  a
mortgage  pool and  entitling the holder  of such a  certificate to pass-through
payment of principal and interest from the pooled mortgage loans, less any  fees
retained  by the pool sponsor."  It appears that, for  purposes of PTE 83-1, the
term "mortgage pool pass-through certificate" would include Certificates  issued
in  a single Class or in multiple Classes that evidence the beneficial ownership
of both  a specified  percentage of  future interest  payments (after  permitted
deductions)  and a specified percentage of  future principal payments on a Trust
Estate.
 
    However, it appears that PTE  83-1 does or might  not apply to the  purchase
and holding of (a) Certificates that evidence the beneficial ownership only of a
specified percentage of future interest payments (after permitted deductions) on
a Trust Estate or only of a specified percentage of future principal payments on
a Trust Estate, (b) Residual Certificates, (c) Certificates evidencing ownership
interests in a Trust Estate which includes Mortgage Loans secured by multifamily
residential  properties or shares issued by cooperative housing corporations, or
(d) Certificates which are subordinated to other Classes of Certificates of such
Series. Accordingly, unless exemptive relief other than PTE 83-1 applies,  Plans
should not purchase any such Certificates.
 
    PTE  83-1 sets forth  "general conditions" and  "specific conditions" to its
applicability.  Section  II  of  PTE  83-1  sets  forth  the  following  general
conditions  to the application of the exemption: (i) the maintenance of a system
of insurance or other protection for  the pooled mortgage loans or the  property
securing  such loans, and for indemnifying certificateholders against reductions
in pass-through payments due  to property damage or  defaults in loan  payments;
(ii)  the  existence of  a pool  trustee who  is  not an  affiliate of  the pool
sponsor; and  (iii) a  requirement that  the sum  of all  payments made  to  and
retained  by the pool sponsor, and all funds  inuring to the benefit of the pool
sponsor as a result of the  administration of the mortgage pool, must  represent
not  more  than  adequate  consideration for  selling  the  mortgage  loans plus
reasonable compensation for services provided by  the pool sponsor to the  pool.
The  system of  insurance or  protection referred  to in  clause (i)  above must
provide such protection and  indemnification up to an  amount not less than  the
greater  of one percent of the aggregate  unpaid principal balance of the pooled
mortgages or the unpaid principal balance  of the largest mortgage in the  pool.
It  should be noted that in promulgating PTE 83-1 (and a predecessor exemption),
the Department did not  have under its consideration  interests in pools of  the
exact nature as some of the Certificates described herein.
 
EXEMPT PLANS
 
    Employee  benefit plans which are governmental  plans (as defined in Section
3(32) of ERISA), and certain church plans (as defined in Section 3(33) of ERISA)
are not subject to ERISA requirements and  assets of such plans may be  invested
in  Certificates without regard to the  ERISA considerations described above but
such plans may  be subject  to the provisions  of other  applicable federal  and
state law.

UNRELATED BUSINESS TAXABLE INCOME--RESIDUAL CERTIFICATES
 
    The  purchase  of  a  Residual  Certificate  by  any  employee  benefit plan
qualified under Code Section 401(a) and exempt from taxation under Code  Section
501(a),  including most  varieties of ERISA  Plans, may give  rise to "unrelated
business taxable  income"  as  described  in Code  Sections  511-515  and  860E.
Further,   prior  to  the  purchase  of  Residual  Certificates,  a  prospective
transferee may be required to  provide an affidavit to  a transferor that it  is
not,  nor is it purchasing a Residual  Certificate on behalf of, a "Disqualified
Organization," which term as defined above includes certain tax-exempt  entities
not subject to Code Section 511 such as certain governmental plans, as discussed
above under the caption "Certain Federal Income Tax Consequences--Federal Income
Tax Consequences for REMIC Certificates--Taxation of Residual
Certificates--Tax-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  investment decisions for  mortgage related securities.
The National  Credit Union  Administration  has adopted  rules, codified  as  12
C.F.R. Section 703.5(f)-(k), which 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, and the April 15, 1994 Interim Revision thereto. 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
 
                                       97
<PAGE>
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 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, unless  otherwise  specified  in  the related
Prospectus Supplement, 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.
 
                                       98
<PAGE>
    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, the  Sole Servicer  and the  Master
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.
