                         5% SUBORDINATED NOTES DUE 2014

                  Mellon Funding Corporation, a corporation duly organized and
existing under the laws of the Commonwealth of Pennsylvania (herein called the
"Company", which term includes any successor corporation under the Indenture
hereinafter referred to), for value received, hereby promises to pay to Cede &
Co., or registered assigns, the principal sum of THREE HUNDRED MILLION DOLLARS
($300,000,000) on December 1, 2014, and to pay interest thereon from November
25, 2002, or from the most recent Interest Payment Date to which interest has
been paid or duly provided for, semi-annually on June 1 and December 1 in each

that the payment of such interest shall be legally enforceable) at the rate of
5% per annum on any overdue principal and premium and on any overdue installment
of interest. The interest so payable, and punctually paid or duly provided for,
on any Interest Payment Date will, as provided in such Indenture, be paid to the
Person in whose name this Security (or one or more Predecessor Securities) is
registered at the close of business on the Regular Record Date for such
interest, which shall be the May 15 or November 15 whether or not a Business

                                                                    Exhibit 4.11

Payment Date. Any such interest not so punctually paid or duly provided for will
forthwith cease to be payable to the Holder on such Regular Record Date and may
either be paid to the Person in whose name this Security (or one or more
Predecessor Securities) is registered at the close of business on a Special
Record Date for the payment of such Defaulted Interest to be fixed by the
Trustee, notice whereof shall be given to Holders of Securities of this series
not less than 10 days prior to such Special Record Date, or be paid at any time
in any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Securities of this series may be listed, and
upon such notice as may be required by such exchange, all as more fully provided
in said Indenture.

                  If this Security is a Global Security (as specified on the
face hereof), this Security is exchangeable in whole for definitive Securities
of this series in registered form ("Registered Securities") of like tenor and of
an equal aggregate principal amount only if (i) the Depositary notifies the
Company that it is unwilling or unable or no longer qualifies to continue as
Depositary for this Global Security and the Company does not appoint another
institution to act as Depositary, (ii) the Company executes and delivers to the
Trustee a Company Order providing that this Global Security shall be
exchangeable for definitive Registered Securities or (iii) any event shall have
happened and be continuing which, after notice or lapse of time, or both, would
become an Event of Default with respect to the Securities of the series of which
this Global Security is a part. In the event this Global Security is
exchangeable pursuant to the preceding sentence, it shall be exchanged in whole
for definitive Registered Securities of this series, of like tenor and of an
equal aggregate principal amount in denominations of U.S. $1,000 and integral
multiples thereof; PROVIDED that, in the case of clauses (ii) and (iii) above,
definitive Registered Securities of this series will be issued in exchange for
this Global Security only if such definitive Registered Securities were
requested by written notice to the Security Registrar by or on behalf of a
Person who is a beneficial owner of an interest herein given through the Holder
hereof. Any definitive Registered Securities of this series issued in exchange
for this Global Security shall be registered in the name or names of such Person
or Persons as the Holder hereof shall instruct the Security Registrar. Except as
provided above, owners of beneficial interests in this Global Security will not
be entitled to receive physical delivery of Securities in definitive form and
will not be considered the Holders thereof for any purpose under the Indenture.

                  If this Security is a Global Security, except as provided in
the next paragraph, no beneficial owner of any portion of this Global Security
shall be entitled to receive payment of accrued interest hereon until this
Global Security has been exchanged for one or more definitive Registered
Securities of this series, as provided herein and in the Indenture.

                  If this Security is a Global Security and if a definitive
Registered Security or Registered Securities of this series are issued in
exchange for this Global Security after the close of business at the office or
agency where such exchange occurs on (i) any Regular Record Date and before the
opening of business at such office or agency on the related Interest Payment
Date, or (ii) any Special Record Date and before the opening of business at such
office or agency on the related proposed date for payment of Defaulted Interest
or interest on Defaulted Interest, as the case may be, accrued interest will not
be payable on such Interest Payment Date or proposed date for payment, as the
case may be, in respect of such Registered Security, but will be payable on such
Interest Payment Date or proposed date for payment, as the case may be, only to
the Holder hereof, and the Holder hereof will undertake in such circumstances to
credit such interest

to the account or accounts of the Persons who were the beneficial owners of any
portion of this Global Security on such Regular Record Date or Special Record
Date, as the case may be.

                  If this Security is a Global Security, payment of the
principal of and any premium or interest hereon will be made on each Interest
Payment Date and at the Maturity Date, as the case may be, by the Trustee by
wire transfer of immediately available funds, in such coin or currency of the
United States of America as at the time of payment is legal tender for payment
of public and private debts, to an account of the registered Holder hereof at
the Federal Reserve Bank of New York, PROVIDED, that, payment at the Maturity
Date hereof shall be made against presentation of this Security at the office of
the Trustee, currently located at 1 Bank One Plaza, Chicago, IL 60670.

                    If this Security is not a Global Security, (i) the principal
of and any interest and premium hereon payable at the Maturity Date hereof will
be paid in immediately available funds, in such coin or currency of the United
States of America as at the time of payment is legal tender for payment of
public and private debts, against presentation of this Security at the
aforementioned office of the Trustee, and (ii) all interest payments hereon
other than interest due at the Maturity Date hereof will be made by check drawn
on the Trustee and mailed by the Trustee to the person entitled thereto as
provided herein, PROVIDED, that Holders of $10,000,000 or more in aggregate
principal amount of Securities of this series shall be entitled to receive such
payments by wire transfer of immediately available funds if appropriate wire
transfer instructions have been received in writing by the Trustee not less than
16 days prior to the applicable Interest Payment Date.

                  Reference is hereby made to the further provisions of this
Security set forth on the reverse hereof, which further provisions shall for all
purposes have the same effect as if set forth at this place.

                  This Security is not a deposit and is not insured by any
federal agency.

                  Unless the certificate of authentication hereon has been
executed by the Trustee referred to on the reverse hereof, or an Authenticating
Agent, by manual signature, neither this Security nor the Guarantee endorsed
hereon shall be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

                                                                    Exhibit 4.11

                  This Security is one of a duly authorized series of Securities
of the Company (herein called the "Securities"), of the series hereinafter
specified, issued and to be issued under an Indenture, dated as of June 12,
2000, as supplemented by the First Supplemental Indenture, dated as of April 30,
2001 (herein called the "Indenture"), among the Company, the Guarantor and Bank
One Trust Company, N.A., as Trustee (herein called the "Trustee", which term
includes any successor trustee under the Indenture), to which Indenture and all
indentures supplemental thereto reference is hereby made for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of
the Company, the Guarantor, the Trustee, the Holders of the Senior Indebtedness
of the Company and the Guarantor and the Holders of the Securities and of the
terms upon which the Securities are, and are to be, authenticated and delivered.
The Securities may be issued in different series, as in the Indenture provided.
This Security is one of the series designated on the face hereof, issued under
and entitled to the benefits of the Indenture and issued in an aggregate
principal amount of $300,000,000.

                  The Securities of this series are redeemable at the option of
the Company, upon not less than 30 days nor more than 60 days' notice by mail,
at any time, at a Redemption Price equal to the greater of (i) 100% of the
principal amount of the Securities redeemed or (ii) the sum of the present
values of the Remaining Scheduled Payments on this Security, discounted to such
redemption date on a semiannual basis, assuming a 360-day year consisting of
twelve 30-day months, at the Treasury Rate plus 20 basis points. In either case,
the Redemption Price shall also include interest accrued to the date of
redemption on the principal balance of this Security to be redeemed.

                  "Treasury Rate" means an annual rate equal to the semiannual
                  equivalent yield to maturity of the Comparable Treasury Issue
                  (as defined below), assuming a price for the Comparable
                  Treasury Issue (expressed as a percentage of its principal
                  amount) equal to the Comparable Treasury Price for the
                  redemption date. The semiannual equivalent yield to maturity
                  will be computed as of the second Business Day immediately
                  preceding the redemption date.

                  "Comparable Treasury Issue" means the United States Treasury
                  security selected by an independent investment banking firm
                  that would be used, at the time of selection and in accordance
                  with customary financial practice, in pricing new issues of
                  corporate debt securities of comparable maturity to the
                  remaining term of the Securities. The term "independent
                  investment banking firm" means one of the Reference Treasury
                  Dealers that the Company appoints.

                  "Comparable Treasury Price" means, with respect to any
                  redemption date, (i) the average of the bid and asked prices
                  for the Comparable Treasury Issue (expressed in each case as a
                  percentage of its principal amount) on the third Business Day
                  preceding such redemption date, as set forth in the daily
                  statistical release (or any successor release) published by
                  the Federal Reserve Bank of New York and designated "Composite
                  3:30 p.m. Quotations for U.S. Government Securities" or (ii)
                  if such release (or any successor release) is not published or
                  does not contain such prices on such business day, (A) the
                  average of the Reference Treasury

<PAGE>
                                   [SPECIMEN]

                                                                    Exhibit 4.11

                  Dealer Quotations for such redemption date, after excluding
                  the highest and lowest of such Reference Treasury Dealer
                  Quotations, or (B) if the Trustee obtains fewer than four such
                  Reference Treasury Dealer Quotations, the average of all such
                  Quotations.

                  "Reference Treasury Dealer" means each of Credit Suisse First
                  Boston Corporation (and its successors), and any three other
                  nationally recognized investment banking firms that the
                  Company shall appoint from time to time that are primary
                  dealers of U.S. government securities in New York City (each,
                  a "Reference Treasury Dealer"). If any of the firms named in
                  the preceding sentence ceases to be a primary dealer of U.S.
                  government securities in New York City, the Company shall
                  appoint another nationally recognized investment banking firm
                  as a substitute.

                  "Reference Treasury Dealer Quotation" means, with respect to
                  any Redemption Date, the average, as determined by the
                  Trustee, of the bid and asked prices for the Comparable
                  Treasury Issue, expressed in each case as a percentage of its
                  principal amount, quoted in writing to the Trustee by a
                  Reference Treasury Dealer as of 3:30 p.m., New York time, on
                  the third Business Day preceding that redemption date. The
                  Trustee shall seek Reference Treasury Dealer Quotations in
                  respect of any Redemption Date from each of the then-existing
                  Reference Treasury Dealers.

                  "Remaining Scheduled Payments" means, with respect to each
                  Security being redeemed, the remaining scheduled payments of
                  principal and interest on that Security that would be due
                  after the related Redemption Date but for the redemption. If,
                  however, the Redemption Date is not an Interest Payment Date
                  with respect to that Security, the amount of the next
                  succeeding scheduled interest payment on that Security that
                  would have been due will be deemed reduced by the amount of
                  interest accrued on the Security to the redemption date.

                  The Company reserves the right from time to time, without
notice to or the consent of the Holders of the Securities, to create and issue
further notes ranking equally and ratably with the Securities in all respects,
or in all respects except for the payment of interest accruing prior to the
issue date or except for the first payment of interest following the issue date
of those further securities. Any further securities will be consolidated and
form a single series with the Securities and will have the same terms as to
status, redemption or otherwise as the Securities. Any further securities may be
issued pursuant to a resolution of the board of directors of the Company, a
supplement to the Indenture, or under an officers' certificate pursuant to the
Indenture.

                  If an Event of Default with respect to Securities of this
series shall occur and be continuing, the principal of the Securities of this
series may be declared due and payable in the manner and with the effect
provided in the Indenture. Upon payment (i) of the amount of principal so
declared due and payable and (ii) of interest on any overdue principal and
overdue interest (in each case to the extent that the payment of such interest
shall be legally enforceable),

                                                                    Exhibit 4.11

all of the Company's obligations in respect of the payment of the principal of
and interest on the Securities of this series shall terminate.

                  The indebtedness evidenced by this Security is, to the extent
provided in the Indenture, subordinate and subject in right of payment to the
prior payment in full of all Senior Indebtedness of the Company, and this
Security is issued subject to the provisions of the Indenture with respect
thereto. Each Holder of this Security, by accepting the same, (a) agrees to and
shall be bound by such provisions, (b) authorizes and directs the Trustee on his
behalf to take such action as may be necessary or appropriate to effectuate the
subordination so provided and (c) appoints the Trustee his attorney-in-fact for
any and all such purposes.

                  The Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and
obligations of the Company and the Guarantor and the rights of the Holders of
the Securities of each series to be affected under the Indenture at any time by
the Company, the Guarantor and the Trustee with the consent of the Holders of
not less than 66 2/3% in aggregate principal amount of the Securities at the
time Outstanding of each series to be affected. The Indenture also contains
provisions permitting the Holders of specified percentages in aggregate
principal amount of the Securities of each series at the time Outstanding, on
behalf of the Holders of all Securities of such series, to waive compliance by
the Company or the Guarantor with certain provisions of the Indenture and
certain past defaults under the Indenture and their consequences. Any such
consent or waiver by the Holder of this Security shall be conclusive and binding
upon such Holder and upon all future Holders of this Security and of any
Security issued upon the registration of transfer hereof or in exchange herefor
or in lieu hereof, whether or not notation of such consent or waiver is made
upon this Security.

                  The Guarantor, or a Subsidiary thereof, may directly assume,
by a supplemental indenture, the due and punctual payment of the principal of
(and premium, if any) and interest on all the Securities, in which case the
Company shall be released from its liability as obligor on the Securities.

                  No reference herein to the Indenture and no provision of this
Security or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of (and
premium, if any) and interest on this Security at the times, places and rate,
and in the coin or currency, herein prescribed.

                  As provided in the Indenture and subject to certain
limitations therein set forth, the transfer of this Security is registrable in
the Security Register, upon surrender of this Security for registration of
transfer at the office or agency of the Company, in the place referred to on the
face hereof, where the principal of (and premium, if any) and interest on this
Security are payable, duly endorsed by, or accompanied by a written instrument
of transfer in form satisfactory to the Company and the Security Registrar duly
executed by, the Holder hereof or his attorney duly authorized in writing, and
thereupon one or more new Securities of this series and of like tenor, of
authorized denominations and for the same aggregate principal amount, will be
issued to the designated transferee or transferees.

                  The Securities of this series are issuable only in registered
form without coupons in denominations of $1,000 and any integral multiple
thereof. As provided in the Indenture and subject to certain limitations therein
set forth, Securities of this series are exchangeable for a like aggregate
principal amount of Securities of this series and of like tenor and of a
different authorized denomination, as requested by the Holder surrendering the
same.

                  No service charge shall be made for any such registration of
transfer or exchange, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

                  Prior to due presentment of this Security for registration of
transfer, the Company, the Guarantor and the Trustee and any agent of the
Company, the Guarantor or the Trustee may treat the Person in whose name this
Security is registered as the owner hereof for all purposes, whether or not this
Security be overdue, and neither the Company, the Guarantor, the Trustee nor any
such agent shall be affected by notice to the contrary.

                  All terms used in this Security which are defined in the
Indenture shall have the meanings assigned to them in the Indenture.

          (a) The Depositor, concurrently with the execution and delivery
hereof, hereby sells, transfers, assigns, sets over and otherwise conveys to the

the Mortgage Loans, including all interest and principal received on or with
respect to the Mortgage Loans (other than payments of principal and interest due
and payable on the Mortgage Loans on or before the Cut-Off Date). The foregoing
sale, transfer, assignment and set over does not and is not intended to result
in a creation of an assumption by the Trustee of any obligation of the Depositor
or any other Person in connection with the Mortgage Loans or any agreement or
instrument relating thereto, except as specifically set forth herein.

          (b) In connection with such transfer and assignment, the Depositor has

     Trustee, without recourse," with all necessary intervening endorsements
     showing a complete chain of endorsement from the originator to the Trustee

     interest of the party so endorsing, as noteholder or assignee thereof, in
     and to that Mortgage Note);

          (ii)    except as provided below, the original recorded Mortgage with
     evidence of a recording thereon, or if any such Mortgage has not been
     returned from the applicable recording office or has been lost, or if such
     public recording office retains the original recorded Mortgage, a copy of
     such Mortgage certified by the Depositor as being a true and correct copy
     of the Mortgage;

          (iii)   subject to the provisos at the end of this paragraph, a duly
     executed Assignment of Mortgage to "          , as trustee for the holders

     or assignments), together with, except as provided below, originals of all
     interim recorded assignments of such mortgage or a copy of such interim
     assignment certified by the Depositor as being a true

                                      -24-

<PAGE>

     and complete copy of the original recorded intervening assignments of
     Mortgage (each such assignment, when duly and validly completed, to be in
     recordable form and sufficient to effect the assignment of and transfer to
     the assignee thereof, under the Mortgage to which the assignment relates);
     provided that, if the related Mortgage has not been returned from the
     applicable public recording office, such Assignment of Mortgage may exclude
     the information to be provided by the recording office; and provided,
     further, if the related Mortgage has been recorded in the name of Mortgage
     Electronic Registration Systems, Inc. ("MERS") or its designee, no
     Assignment of Mortgage in favor of the Trustee will be required to be
     prepared or delivered and instead, the Servicer shall take all actions as
     are necessary to cause the Trust to be shown as the owner of the related
     Mortgage Loan on the records of MERS for purposes of the system of
     recording transfers of beneficial ownership of mortgages maintained by
     MERS;

          (iv)    the originals of all assumption, modification, consolidation
     or extension agreements, if any, with evidence of recording thereon, if
     any;

          (v)     the original or duplicate original mortgagee title insurance
     policy and all riders thereto;

     indicated thereon, or, if the lease is in the process of being recorded, a
     photocopy of the lease, certified by an officer of the respective prior
     owner of such Mortgage Loan or by the applicable title insurance company,
     closing/settlement/escrow agent or company or closing attorney to be a true
     and correct copy of the lease transmitted for recordation;

          (viii)  the original of any security agreement, chattel mortgage or
     equivalent document executed in connection with the Mortgage; and

          (ix)    for each Mortgage Loan secured by Co-op Shares, the originals
     of the following documents or instruments:

                  (B) The stock power executed in blank;

          recording thereon; and

                                      -25-

<PAGE>

                  (G) Executed UCC-3 financing statements or other appropriate
          UCC financing statements required by state law, evidencing a complete
          and unbroken line from the mortgagee to the Trustee with evidence of
          recording thereon (or in a form suitable for recordation).

provided, however, that on the Closing Date, with respect to item (iii), the
Depositor has delivered to the Trustee a copy of such Assignment of Mortgage in
blank and has caused the Servicer to retain the completed Assignment of Mortgage
for recording as described below, unless such Mortgage has been recorded in the
name of MERS or its designee. In addition, if the Depositor is unable to deliver
or cause the delivery of any original Mortgage Note due to the loss of such
original Mortgage Note, the Depositor may deliver a copy of such Mortgage Note,
together with a lost note affidavit, and shall thereby be deemed to have
satisfied the document delivery requirements of this Section 2.01(b). As set
forth on Exhibit L attached hereto is a list of all states where recordation is
required by either Rating Agency to obtain the initial ratings of the
Certificates. The Trustee may rely and shall be protected in relying upon the
information contained in such Exhibit L.

          If in connection with any Mortgage Loans, the Depositor cannot deliver
(A) the Mortgage, (B) all interim recorded assignments, (C) all assumption,
modification, consolidation or extension agreements, if any, or (D) the lender's
title policy (together with all riders thereto) satisfying the requirements of
clause (ii), (iii), (iv) or (v) above, respectively, concurrently with the
execution and delivery hereof because such document or documents have not been
returned from the applicable public recording office in the case of clause (ii),
(iii) or (iv) above, or because the title policy has not been delivered to
either the Servicer or the Depositor by the applicable title insurer in the case
of clause (v) above, the Depositor shall promptly deliver or cause to be
delivered to the Trustee or the Custodian on behalf of the Trustee, in the case
of clause (ii), (iii) or (iv) above, such Mortgage, such interim assignment or
such assumption, modification, consolidation or extension agreement, as the case
may be, with evidence of recording indicated thereon upon receipt thereof from
the public recording office, but in no event shall any such delivery of any such
documents or instruments be made later than one year following the Closing Date,
unless, in the case of clause (ii), (iii) or (iv) above, there has been a
continuing delay at the applicable recording office or, in the case of clause
(v), there has been a continuing delay at the applicable insurer and the
Depositor has delivered the Officer's Certificate to such effect to the Trustee.
The Depositor shall forward or cause to be forwarded to the Trustee (1) from
time to time additional original documents evidencing an assumption or
modification of a Mortgage Loan and (2) any other documents required to be
delivered by the Depositor or the Servicer to the Trustee or the Custodian on
the Trustee's behalf. In the event that the original Mortgage is not delivered
and in connection with the payment in full of the related Mortgage Loan the
public recording office requires the presentation of a "lost instruments
affidavit and indemnity" or any equivalent document, because only a copy of the
Mortgage can be delivered with the instrument of satisfaction or reconveyance,
the Servicer shall prepare, execute and deliver or cause to be prepared,
executed and delivered, on behalf of the Trust, such a document to the public
recording office.

          As promptly as practicable subsequent to such transfer and assignment,
and in any event, within 30 days thereafter, the Servicer shall (except for any
Mortgage which has been recorded in the name of MERS or its designee) (I) cause
each Assignment of Mortgage to be in

                                      -26-

<PAGE>

proper form for recording in the appropriate public office for real property
records within 30 days of the Closing Date and (II) at the Depositor's expense,
cause to be delivered for recording in the appropriate public office for real
property records the Assignments of the Mortgages to the Trustee, except that,
with respect to any Assignment of a Mortgage as to which the Servicer has not
received the information required to prepare such assignment in recordable form,
the Servicer's obligation to do so and to deliver the same for such recording
shall be as soon as practicable after receipt of such information and in any
event within 30 days after the receipt thereof and, no recording of an
Assignment of Mortgage will be required in a state if either (i) the Depositor
furnishes to the Trustee an unqualified Opinion of Counsel reasonably acceptable
to the Trustee to the effect that recordation of such assignment is not
necessary under applicable state law to preserve the Trustee's interest in the
related Mortgage Loan against the claim of any subsequent transferee of such
Mortgage Loan or any successor to, or creditor of, the Depositor or the
originator of such Mortgage Loan or (ii) the recordation of an Assignment of
Mortgage in such state is not required by either Rating Agency in order to
obtain the initial ratings on the Certificates on the Closing Date.

          In the case of Mortgage Loans that have been prepaid in full as of the
Closing Date, the Depositor, in lieu of delivering the above documents to the
Trustee, or the Custodian on the Trustee's behalf, will cause the Servicer to
deposit in the Servicer Custodial Account the portion of such payment that is
required to be deposited in the Servicer Custodial Account pursuant to Section
3.08.

          Section 2.02 Acceptance by the Trustee of the Mortgage Loans. Subject
to the provisions of the following paragraph, the Trustee declares that it, or
the Custodian as its agent, will hold the documents referred to in Section 2.01
and the other documents delivered to it constituting the Mortgage Files, and
that it will hold such other assets as are included in the Trust Estate, in
trust for the exclusive use and benefit of all present and future
Certificateholders.

          Within 90 days after the execution and delivery of this Agreement, the
Trustee shall review, or cause the Custodian to review, the Mortgage Files in
its possession. If, in the course of such review, the Trustee or the Custodian
finds any document constituting a part of a Mortgage File which does not meet
the requirements of Section 2.01 or is omitted from such Mortgage File, the
Trustee shall promptly so notify the Servicer and the Depositor, or shall cause
the Custodian to promptly so notify the Servicer and the Depositor. In
performing any such review, the Trustee or the Custodian may conclusively rely
on the purported genuineness of any such document and any signature thereon. It
is understood that the scope of the Trustee's or the Custodian's review of the
Mortgage Files is limited solely to confirming that the documents listed in
Section 2.01 have been received and further confirming that any and all
documents delivered pursuant to Section 2.01 appear on their face to have been
executed and relate to the Mortgage Loans identified in the Mortgage Loan
Schedule. Neither the Trustee nor the Custodian shall have any responsibility
for determining whether any document is valid and binding, whether the text of
any assignment or endorsement is in proper or recordable form, whether any
document has been recorded in accordance with the requirements of any applicable
jurisdiction, or whether a blanket assignment is permitted in any applicable
jurisdiction. The Depositor hereby covenants and agrees that it will promptly
correct or cure such defect within 90 days from the date it was so notified of
such defect and, if the Depositor does not correct or cure such defect within
such period, the Depositor will either (a) substitute for the related Mortgage

                                      -27-

<PAGE>

Loan a Substitute Mortgage Loan, which substitution shall be accomplished in the
manner and subject to the conditions set forth below or (b) purchase such
Mortgage Loan from the Trustee at the Repurchase Price for such Mortgage Loan;
provided, however, that in no event shall such a substitution occur more than
two years from the Closing Date; provided, further, that such substitution or
repurchase shall occur within 90 days of when such defect was discovered if such
defect will cause the Mortgage Loan not to be a "qualified mortgage" within the
meaning of Section 860G(a)(3) of the Code.

          With respect to each Substitute Mortgage Loan the Depositor shall
deliver to the Trustee, for the benefit of the Certificateholders, the Mortgage
Note, the Mortgage, the related Assignment of Mortgage (except for any Mortgage
which has been recorded in the name of MERS or its designee), and such other
documents and agreements as are otherwise required by Section 2.01, with the
Mortgage Note endorsed and the Mortgage assigned as required by Section 2.01. No
substitution is permitted to be made in any calendar month after the
Determination Date for such month. Monthly Payments due with respect to any such
Substitute Mortgage Loan in the month of substitution shall not be part of the
Trust Estate and will be retained by the Depositor. For the month of
substitution, distributions to Certificateholders will include the Monthly
Payment due for such month on any Defective Mortgage Loan for which the
Depositor has substituted a Substitute Mortgage Loan.

          The Servicer shall amend the Mortgage Loan Schedule for the benefit of
the Certificateholders to reflect the removal of each Mortgage Loan that has
become a Defective Mortgage Loan and the substitution of the Substitute Mortgage
Loan or Loans and the Servicer shall deliver the amended Mortgage Loan Schedule
to the Trustee and the Custodian. Upon such substitution, each Substitute
Mortgage Loan shall be subject to the terms of this Agreement in all respects,
and the Depositor shall be deemed to have made to the Trustee with respect to
such Substitute Mortgage Loan, as of the date of substitution, the
representations and warranties made pursuant to Section 2.04. Upon any such
substitution and the deposit to the Servicer Custodial Account of any required
Substitution Adjustment Amount (as described in the next paragraph) and receipt
of a Request for Release, the Trustee shall release, or shall direct the
Custodian to release, the Mortgage File relating to such Defective Mortgage Loan
to the Depositor and shall execute and deliver at the Depositor's direction such
instruments of transfer or assignment prepared by the Depositor, in each case
without recourse, as shall be necessary to vest title in the Depositor, or its
designee, to the Trustee's interest in any Defective Mortgage Loan substituted
for pursuant to this Section 2.02.

          For any month in which the Depositor substitutes one or more
Substitute Mortgage Loans for one or more Defective Mortgage Loans, the amount
(if any) by which the aggregate principal balance of all such Substitute
Mortgage Loans as of the date of substitution is less than the aggregate Stated
Principal Balance of all such Defective Mortgage Loans (after application of the
principal portion of the Monthly Payments due in the month of substitution) (the
"Substitution Adjustment Amount") plus an amount equal to the aggregate of any
unreimbursed Advances with respect to such Defective Mortgage Loans shall be
deposited into the Certificate Account by the Depositor on or before the
Remittance Date for the Distribution Date in the month succeeding the calendar
month during which the related Mortgage Loan is required to be purchased or
replaced hereunder.

                                      -28-

<PAGE>

          The Trustee shall retain or shall cause the Custodian to retain
possession and custody of each Mortgage File in accordance with and subject to
the terms and conditions set forth herein. The Servicer shall promptly deliver
to the Trustee, upon the execution or, in the case of documents requiring
recording, receipt thereof, the originals of such other documents or instruments
constituting the Mortgage File as come into the Servicer's possession from time
to time.

          It is understood and agreed that the obligation of the Depositor to
substitute for or to purchase any Mortgage Loan which does not meet the
requirements of Section 2.01 shall constitute the sole remedy respecting such
defect available to the Trustee and any Certificateholder against the Depositor.

          The Trustee or the Custodian, on behalf of the Trustee, shall be under
no duty or obligation (i) to inspect, review or examine any such documents,
instruments, certificates or other papers to determine that they are genuine,
enforceable, or appropriate for the represented purpose or that they are other
than what they purport to be on their face or (ii) to determine whether any
Mortgage File should include any of the documents specified in Section
2.01(b)(iv), (vi), (vii) and (viii).

          Section 2.03 Representations, Warranties and Covenants of the
Servicer.

          The Servicer hereby makes the following representations and warranties
to the Depositor and the Trustee, as of the Closing Date:

          (i)     The Servicer is a national banking association duly organized,
     validly existing, and in good standing under the federal laws of the United
     States of America and has all licenses necessary to carry on its business
     as now being conducted and is licensed, qualified and in good standing in
     each of the states where a Mortgaged Property is located if the laws of
     such state require licensing or qualification in order to conduct business
     of the type conducted by the Servicer. The Servicer has power and authority
     to execute and deliver this Agreement and to perform in accordance
     herewith; the execution, delivery and performance of this Agreement
     (including all instruments of transfer to be delivered pursuant to this
     Agreement) by the Servicer and the consummation of the transactions
     contemplated hereby have been duly and validly authorized. This Agreement,
     assuming due authorization, execution and delivery by the other parties
     hereto, evidences the valid, binding and enforceable obligation of the
     Servicer, subject to applicable law except as enforceability may be limited
     by (A) bankruptcy, insolvency, liquidation, receivership, moratorium,
     reorganization or other similar laws affecting the enforcement of the
     rights of creditors and (B) general principles of equity, whether
     enforcement is sought in a proceeding in equity or at law. All requisite
     corporate action has been taken by the Servicer to make this Agreement
     valid and binding upon the Servicer in accordance with its terms.

          (ii)    No consent, approval, authorization or order is required for
     the transactions contemplated by this Agreement from any court,
     governmental agency or body, or federal or state regulatory authority
     having jurisdiction over the Servicer is required or, if

                                      -29-

<PAGE>

     required, such consent, approval, authorization or order has been or will,
     prior to the Closing Date, be obtained.

          (iii)   The consummation of the transactions contemplated by this
     Agreement are in the ordinary course of business of the Servicer and will
     not result in the breach of any term or provision of the charter or by-laws
     of the Servicer or result in the breach of any term or provision of, or
     conflict with or constitute a default under or result in the acceleration
     of any obligation under, any agreement, indenture or loan or credit
     agreement or other instrument to which the Servicer or its property is
     subject, or result in the violation of any law, rule, regulation, order,
     judgment or decree to which the Servicer or its property is subject.

          (iv)    There is no action, suit, proceeding or investigation pending
     or, to the best knowledge of the Servicer, threatened against the Servicer
     which, either individually or in the aggregate, would result in any
     material adverse change in the business, operations, financial condition,
     properties or assets of the Servicer, or in any material impairment of the
     right or ability of the Servicer to carry on its business substantially as
     now conducted or which would draw into question the validity of this
     Agreement or the Mortgage Loans or of any action taken or to be taken in
     connection with the obligations of the Servicer contemplated herein, or
     which would materially impair the ability of the Servicer to perform under
     the terms of this Agreement.

          The representations and warranties made pursuant to this Section 2.03
shall survive delivery of the respective Mortgage Files to the Trustee for the
benefit of the Certificateholders.

          Section 2.04 Representations and Warranties of the Depositor as to the
Mortgage Loans.

          The Depositor hereby represents and warrants to the Trustee with
respect to the Mortgage Loans or each Mortgage Loan, as the case may be, as of
the date hereof or such other date set forth herein that as of the Closing Date:

          (i)       The information set forth in the Mortgage Loan Schedule is
     true and correct in all material respects.

          (ii)      There are no delinquent taxes, ground rents, governmental
     assessments, insurance premiums, leasehold payments, including assessments
     payable in future installments or other outstanding charges affecting the
     lien priority of the related Mortgaged Property.

          (iii)     The terms of the Mortgage Note and the Mortgage have not
     been impaired, waived, altered or modified in any respect, except by
     written instruments, recorded in the applicable public recording office if
     necessary to maintain the lien priority of the Mortgage, and which have
     been delivered to the Trustee; the substance of any such waiver, alteration
     or modification has been approved by the insurer under the Primary
     Insurance Policy, if any, the title insurer, to the extent required by the
     related policy, and is reflected on the Mortgage Loan Schedule. No
     instrument of waiver, alteration or

                                      -30-

<PAGE>

     modification has been executed, and no Mortgagor has been released, in
     whole or in part, except in connection with an assumption agreement
     approved by the insurer under the Primary Insurance Policy, if any, the
     title insurer, to the extent required by the policy, and which assumption
     agreement has been delivered to the Trustee.

          (iv)      The Mortgage Note and the Mortgage are not subject to any
     right of rescission, set-off, counterclaim or defense, including the
     defense of usury, nor will the operation of any of the terms of the
     Mortgage Note and the Mortgage, or the exercise of any right thereunder,
     render either the Mortgage Note or the Mortgage unenforceable, in whole or
     in part, or subject to any right of rescission, set-off, counterclaim or
     defense, including the defense of usury and no such right of rescission,
     set-off, counterclaim or defense has been asserted with respect thereto.

          (v)       All buildings upon the Mortgaged Property are insured by an
     insurer generally acceptable to prudent mortgage lending institutions
     against loss by fire, hazards of extended coverage and such other hazards
     as are customary in the area the Mortgaged Property is located, pursuant to
     insurance policies conforming to the requirements of Customary Servicing
     Procedures and this Agreement. All such insurance policies contain a
     standard mortgagee clause naming the originator of the Mortgage Loan, its
     successors and assigns as mortgagee and all premiums thereon have been
     paid. If the Mortgaged Property is in an area identified on a flood hazard
     map or flood insurance rate map issued by the Federal Emergency Management
     Agency as having special flood hazards (and such flood insurance has been
     made available), a flood insurance policy meeting the requirements of the
     current guidelines of the Federal Insurance Administration is in effect
     which policy conforms to the requirements of FNMA or FHLMC. The Mortgage
     obligates the Mortgagor thereunder to maintain all such insurance at the
     Mortgagor's cost and expense, and on the Mortgagor's failure to do so,
     authorizes the holder of the Mortgage to maintain such insurance at
     Mortgagor's cost and expense and to seek reimbursement therefor from the
     Mortgagor.

          (vi)      Any and all requirements of any federal, state or local law
     including, without limitation, usury, truth in lending, real estate
     settlement procedures, consumer credit protections, equal credit
     opportunity or disclosure laws applicable to the origination and servicing
     of Mortgage Loan have been complied with.

          (vii)     The Mortgage has not been satisfied, canceled, subordinated
     or rescinded, in whole or in part (other than as to Principal Prepayments
     in full which may have been received prior to the Closing Date), and the
     Mortgaged Property has not been released from the lien of the Mortgage, in
     whole or in part, nor has any instrument been executed that would effect
     any such satisfaction, cancellation, subordination, rescission or release.

          (viii)    The Mortgage is a valid, existing and enforceable first lien
     on the Mortgaged Property, including all improvements on the Mortgaged
     Property subject only to (A) the lien of current real property taxes and
     assessments not yet due and payable, (B) covenants, conditions and
     restrictions, rights of way, easements and other matters of the public
     record as of the date of recording being acceptable to mortgage lending
     institutions generally and specifically referred to in the lender's title
     insurance policy delivered to the

                                      -31-

<PAGE>

     originator of the Mortgage Loan and which do not adversely affect the
     Appraised Value of the Mortgaged Property, (C) if the Mortgaged Property
     consists of Co-op Shares, any lien for amounts due to the cooperative
     housing corporation for unpaid assessments or charges or any lien of any
     assignment of rents or maintenance expenses secured by the real property
     owned by the cooperative housing corporation, and (D) other matters to
     which like properties are commonly subject which do not materially
     interfere with the benefits of the security intended to be provided by the
     Mortgage or the use, enjoyment, value or marketability of the related
     Mortgaged Property. Any security agreement, chattel mortgage or equivalent
     document related to and delivered in connection with the Mortgage Loan
     establishes and creates a valid, existing and enforceable first lien and
     first priority security interest on the property described therein and the
     Depositor has the full right to sell and assign the same to the Trustee.

          (ix)      The Mortgage Note and the related Mortgage are genuine and
     each is the legal, valid and binding obligation of the maker thereof,
     enforceable in accordance with its terms except as enforceability may be
     limited by (A) bankruptcy, insolvency, liquidation, receivership,
     moratorium, reorganization or other similar laws affecting the enforcement
     of the rights of creditors and (B) general principles of equity, whether
     enforcement is sought in a proceeding in equity or at law.

          (x)       All parties to the Mortgage Note and the Mortgage had legal
     capacity to enter into the Mortgage Loan and to execute and deliver the
     Mortgage Note and the Mortgage, and the Mortgage Note and the Mortgage have
     been duly and properly executed by such parties.

          (xi)      The proceeds of the Mortgage Loan have been fully disbursed
     to or for the account of the Mortgagor and there is no obligation for the
     Mortgagee to advance additional funds thereunder and any and all
     requirements as to completion of any on-site or off-site improvements and
     as to disbursements of any escrow funds therefor have been complied with.
     All costs fees and expenses incurred in making or closing the Mortgage Loan
     and the recording of the Mortgage have been paid, and the Mortgagor is not
     entitled to any refund of any amounts paid or due to the Mortgagee pursuant
     to the Mortgage Note or Mortgage.

          (xii)     To the best of the Depositor's knowledge, all parties which
     have had any interest in the Mortgage Loan, whether as mortgagee, assignee,
     pledgee or otherwise, are (or, during the period in which they held and
     disposed of such interest, were) in compliance with any and all applicable
     "doing business" and licensing requirements of the laws of the state
     wherein the Mortgaged Property is located.

          (xiii)    The Mortgage Loan is covered by an ALTA lender's title
     insurance policy, acceptable to FNMA or FHLMC, issued by a title insurer
     acceptable to FNMA or FHLMC and qualified to do business in the
     jurisdiction where the Mortgaged Property is located, insuring (subject to
     the exceptions contained in (viii)(A) and (B) above) the Seller, its
     successors and assigns as to the first priority lien of the Mortgage in the
     original principal amount of the Mortgage Loan. The Depositor is the sole
     insured of such lender's title insurance policy, and such lender's title
     insurance policy is in full force

                                      -32-

<PAGE>

     and effect and will be in full force and effect upon the consummation of
     the transactions contemplated by this Agreement. No claims have been made
     under such lender's title insurance policy, and the Depositor has not done,
     by act or omission, anything which would impair the coverage of such
     lender's title insurance policy.

          (xiv)     There is no default, breach, violation or event of
     acceleration existing under the Mortgage or the Mortgage Note and no event
     which, with the passage of time or with notice and the expiration of any
     grace or cure period, would constitute a default, breach, violation or
     event of acceleration, and the Seller has not waived any default, breach,
     violation or event of acceleration.

          (xv)      As of the date of origination of the Mortgage Loan, there
     had been no mechanics' or similar liens or claims filed for work, labor or
     material (and no rights are outstanding that under law could give rise to
     such lien) affecting the relating Mortgaged Property which are or may be
     liens prior to, or equal or coordinate with, the lien of the related
     Mortgage.

          (xvi)     All improvements which were considered in determining the
     Appraised Value of the related Mortgaged Property lay wholly within the
     boundaries and building restriction lines of the Mortgaged Property, and no
     improvements on adjoining properties encroach upon the Mortgaged Property.

          (xvii)    The Mortgage Loan was originated by a commercial bank or
     similar banking institution which is supervised and examined by a federal
     or state authority, or by a mortgagee approved by the Secretary of HUD.

          (xviii)   Principal payments on the Mortgage Loan commenced no more
     than sixty days after the proceeds of the Mortgaged Loan were disbursed.
     The Mortgage Loans are 30-year fixed rate mortgage loans having an original
     term to maturity of not more than 30 years, with interest payable in
     arrears on the first day of the month. Each Mortgage Note requires a
     monthly payment which is sufficient to fully amortize the original
     principal balance over the original term thereof and to pay interest at the
     related Mortgage Interest Rate. The Mortgage Note does not permit negative
     amortization.

          (xix)     There is no proceeding pending or, to the Depositor's
     knowledge, threatened for the total or partial condemnation of the
     Mortgaged Property and such property is in good repair and is undamaged by
     waste, fire, earthquake or earth movement, windstorm, flood, tornado or
     other casualty, so as to affect adversely the value of the Mortgaged
     Property as security for the Mortgage Loan or the use for which the
     premises were intended.

          (xx)      The Mortgage and related Mortgage Note contain customary and
     enforceable provisions such as to render the rights and remedies of the
     holder thereof adequate for the realization against the Mortgaged Property
     of the benefits of the security provided thereby, including (A) in the case
     of a Mortgage designated as a deed of trust, by trustee's sale, and (B)
     otherwise by judicial foreclosure. To the best of the Depositor's
     knowledge, following the date of origination of the Mortgage Loan, the

                                      -33-

<PAGE>

     Mortgaged Property has not been subject to any bankruptcy proceeding or
     foreclosure proceeding and the Mortgagor has not filed for protection under
     applicable bankruptcy laws. There is no homestead or other exemption or
     right available to the Mortgagor or any other person which would interfere
     with the right to sell the Mortgaged Property at a trustee's sale or the
     right to foreclose the Mortgage.

          (xxi)     The Mortgage Note and Mortgage are on forms acceptable to
     FNMA or FHLMC.

          (xxii)    The Mortgage Note is not and has not been secured by any
     collateral except the lien of the corresponding Mortgage on the Mortgaged
     Property and the security interest of any applicable security agreement or
     chattel mortgage referred to in (viii) above.

          (xxiii)   The Mortgage File contains an appraisal of the related
     Mortgaged Property, in a form acceptable to FNMA or FHLMC and such
     appraisal complies with the requirements of FIRREA, and was made and
     signed, prior to the approval of the Mortgage Loan application, by a
     Qualified Appraiser.

          (xxiv)    In the event the Mortgage constitutes a deed of trust, a
     trustee, duly qualified under applicable law to serve as such, has been
     properly designated and currently so serves, and no fees or expenses are or
     will become payable by the Trustee to the trustee under the deed of trust,
     except in connection with a trustee's sale after default by the Mortgagor.

          (xxv)     No Mortgage Loan is a graduated payment mortgage loan, no
     Mortgage Loan has a shared appreciation or other contingent interest
     feature, and no Mortgage Loan contains any "buydown" provision.

          (xxvi)    The Mortgagor has received all disclosure materials required
     by applicable law with respect to the making of mortgage loans of the same
     type as the Mortgage Loan and rescission materials required by applicable
     law if the Mortgage Loan is a Refinance Mortgage Loan.

          (xxvii)   Each Mortgage Loan with a Loan-to-Value Ratio at origination
     in excess of 80% will be subject to a Primary Insurance Policy, issued by
     an insurer acceptable to FNMA or FHLMC, which insures that portion of the
     Mortgage Loan in excess of the portion of the Appraised Value of the
     Mortgaged Property required by FNMA. All provisions of such Primary
     Insurance Policy have been and are being complied with, such policy is in
     full force and effect, and all premiums due thereunder have been paid. Any
     Mortgage subject to any such Primary Insurance Policy obligates the
     Mortgagor thereunder to maintain such insurance and to pay all premiums and
     charges in connection therewith at least until Loan-to-Value Ratio of such
     Mortgage Loan is reduced to less than 80%. The Mortgage Interest Rate for
     the Mortgage Loan does not include any such insurance premium.

          (xxviii)  To the best of the Depositor's knowledge as of the date of
     origination of the Mortgage Loan, (A) the Mortgaged Property is lawfully
     occupied under applicable

                                      -34-

<PAGE>

     law, (B) all inspections, licenses and certificates required to be made or
     issued with respect to all occupied portions of the Mortgaged Property and,
     with respect to the use and occupancy of the same, including but not
     limited to certificates of occupancy, have been made or obtained from the
     appropriate authorities and (C) no improvement located on or part of the
     Mortgaged Property is in violation of any zoning law or regulation.

          (xxix)    The Assignment of Mortgage (except with respect to any
     Mortgage that has been recorded in the name of MERS or its designee) is in
     recordable form and is acceptable for recording under the laws of the
     jurisdiction in which the Mortgaged Property is located.

          (xxx)     All payments required to be made prior to the Cut-Off Date
     for such Mortgage Loan under the terms of the Mortgage Note have been made
     and no Mortgage Loan has been more than 30 days delinquent more than once
     in the twelve month period immediately prior to the Cut-Off Date.

          (xxxi)    With respect to each Mortgage Loan, the Depositor or
     Servicer is in possession of a complete Mortgage File except for the
     documents which have been delivered to the Trustee or which have been
     submitted for recording and not yet returned.

          (xxxii)   Immediately prior to the transfer and assignment
     contemplated herein, the Depositor was the sole owner and holder of the
     Mortgage Loans. The Mortgage Loans were not assigned or pledged by the
     Depositor and the Depositor had good and marketable title thereto, and the
     Depositor had full right to transfer and sell the Mortgage Loans to the
     Trustee free and clear of any encumbrance, participation interest, lien,
     equity, pledge, claim or security interest and had full right and authority
     subject to no interest or participation in, or agreement with any other
     party to sell or otherwise transfer the Mortgage Loans.

          (xxxiii)  Any future advances made prior to the Cut-Off Date have been
     consolidated with the outstanding principal amount secured by the Mortgage,
     and the secured principal amount, as consolidated, bears a single interest
     rate and single repayment term. The lien of the Mortgage securing the
     consolidated principal amount is expressly insured as having first lien
     priority by a title insurance policy, an endorsement to the policy insuring
     the mortgagee's consolidated interest or by other title evidence acceptable
     to FNMA and FHLMC. The consolidated principal amount does not exceed the
     original principal amount of the Mortgage Loan.

          (xxxiv)   The Mortgage Loan was underwritten in accordance with the
     applicable Underwriting Guidelines in effect at the time of origination
     with exceptions thereto exercised in a reasonable manner.

          (xxxv)    If the Mortgage Loan is secured by a long-term residential
     lease, (1) the lessor under the lease holds a fee simple interest in the
     land; (2) the terms of such lease expressly permit the mortgaging of the
     leasehold estate, the assignment of the lease without the lessor's consent
     and the acquisition by the holder of the Mortgage of the rights of the
     lessee upon foreclosure or assignment in lieu of foreclosure or provide the

                                      -35-

<PAGE>

     holder of the Mortgage with substantially similar protections; (3) the
     terms of such lease do not (a) allow the termination thereof upon the
     lessee's default without the holder of the Mortgage being entitled to
     receive written notice of, and opportunity to cure, such default, (b) allow
     the termination of the lease in the event of damage or destruction as long
     as the Mortgage is in existence, (c) prohibit the holder of the Mortgage
     from being insured (or receiving proceeds of insurance) under the hazard
     insurance policy or policies relating to the Mortgaged Property or (d)
     permit any increase in the rent other than pre-established increases set
     forth in the lease; (4) the original term of such lease in not less than 15
     years; (5) the term of such lease does not terminate earlier than five
     years after the maturity date of the Mortgage Note; and (6) the Mortgaged
     Property is located in a jurisdiction in which the use of leasehold estates
     in transferring ownership in residential properties is a widely accepted
     practice.

          (xxxvi)   The Mortgaged Property is located in the state identified in
     the Mortgage Loan Schedule and consists of a parcel of real property with a
     detached single family residence erected thereon, or a two- to four-family
     dwelling, or an individual condominium unit, or an individual unit in a
     planned unit development, or, in the case of Mortgage Loans secured by
     Co-op Shares, leases or occupancy agreements; provided, however, that any
     condominium project or planned unit development generally conforms with the
     applicable Underwriting Guidelines regarding such dwellings, and no
     residence or dwelling is a mobile home or a manufactured dwelling.

          (xxxvii)  The Depositor used no adverse selection procedures in
     selecting the Mortgage Loan for inclusion in the Trust Estate.

          (xxxviii) Each Mortgage Loan is a "qualified mortgage" within Section
     860G(a)(3) of the Code.

          (xxxix)   With respect to each Mortgage where a lost note affidavit
     has been delivered to the Trustee in place of the related Mortgage Note,
     the related Mortgage Note is no longer in existence.

          Notwithstanding the foregoing, no representations or warranties are
made by the Depositor as to the environmental condition of any Mortgaged
Property; the absence, presence or effect of hazardous wastes or hazardous
substances on any Mortgaged Property; any casualty resulting from the presence
or effect of hazardous wastes or hazardous substances on, near or emanating from
any Mortgaged Property; the impact on Certificateholders of any environmental
condition or presence of any hazardous substance on or near any Mortgaged
Property; or the compliance of any Mortgaged Property with any environmental
laws, nor is any agent, Person or entity otherwise affiliated with the Depositor
authorized or able to make any such representation, warranty or assumption of
liability relative to any Mortgaged Property. In addition, no representations or
warranties are made by the Depositor with respect to the absence or effect of
fraud in the origination of any Mortgage Loan.

          It is understood and agreed that the representations and warranties
set forth in this Section 2.04 shall survive delivery of the respective Mortgage
Files to the Trustee or the

                                      -36-

<PAGE>

Custodian and shall inure to the benefit of the Trustee, notwithstanding any
restrictive or qualified endorsement or assignment.

          Upon discovery by either the Depositor, the Servicer, the Trustee or
the Custodian that any of the representations and warranties set forth in this
Section 2.04 is not accurate (referred to herein as a "breach") and that such
breach materially and adversely affects the interests of the Certificateholders
in the related Mortgage Loan, the party discovering such breach shall give
prompt written notice to the other parties (any Custodian being so obligated
under a Custodial Agreement); provided that any such breach that causes the
Mortgage Loan not to be a "qualified mortgage" within the meaning of Section
860G(a)(3) of the Code shall be deemed to materially and adversely affect the
interests of the Certificateholders. Within 90 days of its discovery or its
receipt of notice of any such breach, the Depositor shall cure such breach in
all material respects or shall either (i) repurchase the Mortgage Loan or any
property acquired in respect thereof from the Trustee at a price equal to the
Repurchase Price or (ii) if within two years of the Closing Date, substitute for
such Mortgage Loan in the manner described in Section 2.02; provided that if the
breach would cause the Mortgage Loan to be other than a "qualified mortgage" as
defined in Section 860G(a)(3) of the Code, any such repurchase or substitution
must occur within 90 days from the date the breach was discovered. The
Repurchase Price of any repurchase described in this paragraph and the
Substitution Adjustment Amount, if any, shall be deposited in the Certificate
Account. It is understood and agreed that the obligation of the Depositor to
repurchase or substitute for any Mortgage Loan or Mortgaged Property as to which
such a breach has occurred and is continuing shall constitute the sole remedy
respecting such breach available to Certificateholders, or to the Trustee on
behalf of Certificateholders, and such obligation shall survive until
termination of the Trust hereunder.

          Section 2.05 Designation of Interests in the REMIC. The Depositor
hereby designates the Classes of Class A Certificates (other than the Class A-R
and Class A-LR Certificates) and the Classes of Class B Certificates as classes
of "regular interests" and the Class A-R Certificate as the single class of
"residual interest" in the Upper-Tier REMIC for the purposes of Code Sections
860G(a)(1) and 860G(a)(2), respectively. The Depositor hereby further designates
the Class A-L1 Interest, Class A-L3 Interest, Class A-L4 Interest, Class A-LPO
Interest, Class A-LUR Interest, Class B-L1 Interest, Class B-L2 Interest, Class
B-L3 Interest, Class B-L4 Interest, Class B-L5 Interest and Class B-L6 Interest
as classes of "regular interests" and the Class A-LR Certificate as the single
class of "residual interest" in the Lower-Tier REMIC for the purposes of Code
Sections 860G(a)(1) and 860G(a)(2), respectively.

          Section 2.06 Designation of Start-up Day. The Closing Date is hereby
designated as the "start-up day" of each of the Upper-Tier REMIC and Lower-Tier
REMIC within the meaning of Section 860G(a)(9) of the Code.

          Section 2.07 REMIC Certificate Maturity Date. Solely for purposes of
satisfying Section 1.860G-1(a)(4)(iii) of the Treasury Regulations, the "latest
possible maturity date" of the regular interests in the Upper-Tier REMIC and
Lower-Tier REMIC is          , 20 .

          Section 2.08 Execution and Delivery of Certificates. The Trustee (i)
acknowledges the issuance of and hereby declares that it holds the
Uncertificated Lower-Tier

                                      -37-

<PAGE>

Interests on behalf of the Upper-Tier REMIC and the Certificateholders and (ii)
has executed and delivered to or upon the order of the Depositor, in exchange
for the Mortgage Loans and Uncertificated Lower-Tier Interests together with all
other assets included in the definition of "Trust Estate," receipt of which is
hereby acknowledged, Certificates in authorized denominations which, together
with the Uncertificated Lower-Tier Interests, evidence ownership of the entire
Trust Estate.

                                   ARTICLE III

                          ADMINISTRATION AND SERVICING
                                OF MORTGAGE LOANS

          Section 3.01 Servicer to Service Mortgage Loans. For and on behalf of
the Certificateholders, the Servicer shall service and administer the Mortgage
Loans, all in accordance with the terms of this Agreement, Customary Servicing
Procedures, applicable law and the terms of the Mortgage Notes and Mortgages. In
connection with such servicing and administration, the Servicer shall have full
power and authority, acting alone and/or through Subservicers as provided in
Section 3.02, to do or cause to be done any and all things that it may deem
necessary or desirable in connection with such servicing and administration
including, but not limited to, the power and authority, subject to the terms
hereof, (a) to execute and deliver, on behalf of the Certificateholders and the
Trustee, customary consents or waivers and other instruments and documents, (b)
to consent, with respect to the Mortgage Loans it services, to transfers of any
Mortgaged Property and assumptions of the Mortgage Notes and related Mortgages
(but only in the manner provided in this Agreement), (c) to collect any
Insurance Proceeds and other Liquidation Proceeds relating to the Mortgage Loans
it services, and (d) to effectuate foreclosure or other conversion of the
ownership of the Mortgaged Property securing any Mortgage Loan it services. The
Servicer shall represent and protect the interests of the Trust in the same
manner as it protects its own interests in mortgage loans in its own portfolio
in any claim, proceeding or litigation regarding a Mortgage Loan and shall not
make or permit any modification, waiver or amendment of any term of any Mortgage
Loan, except as provided pursuant to Section 3.21. Without limiting the
generality of the foregoing, the Servicer, in its own name or in the name of any
Subservicer or the Depositor and the Trustee, is hereby authorized and empowered
by the Depositor and the Trustee, when the Servicer or any Subservicer, as the
case may be, believes it appropriate in its reasonable judgment, to execute and
deliver, on behalf of the Trustee, the Depositor, the Certificateholders or any
of them, any and all instruments of satisfaction or cancellation, or of partial
or full release or discharge, and all other comparable instruments, with respect
to the Mortgage Loans it services, and with respect to the related Mortgaged
Properties held for the benefit of the Certificateholders. The Servicer shall
prepare and deliver to the Depositor and/or the Trustee such documents requiring
execution and delivery by either or both of them as are necessary or appropriate
to enable the Servicer to service and administer the Mortgage Loans it services
to the extent that the Servicer is not permitted to execute and deliver such
documents pursuant to the preceding sentence. Upon receipt of such documents,
the Depositor and/or the Trustee, upon the direction of the Servicer, shall
promptly execute such documents and deliver them to the Servicer.

                                      -38-

<PAGE>

          In accordance with the standards of the preceding paragraph, the
Servicer shall advance or cause to be advanced funds as necessary for the
purpose of effecting the payment of taxes and assessments on the Mortgaged
Properties relating to the Mortgage Loans it services, which Servicing Advances
shall be reimbursable in the first instance from related collections from the
Mortgagors pursuant to Section 3.09, and further as provided in Section 3.11.
The costs incurred by the Servicer, if any, in effecting the timely payments of
taxes and assessments on the Mortgaged Properties and related insurance premiums
shall not, for the purpose of calculating monthly distributions to the
Certificateholders, be added to the Stated Principal Balances of the related
Mortgage Loans, notwithstanding that the terms of such Mortgage Loans so permit.

          The relationship of the Servicer (and of any successor to the Servicer
as servicer under this Agreement) to the Trustee under this Agreement is
intended by the parties to be that of an independent contractor and not that of
a joint venturer, partner or agent.

          Section 3.02 Subservicing; Enforcement of the Obligations of Servicer.

          (a) The Servicer may arrange for the subservicing of any Mortgage Loan
it services by a Subservicer pursuant to a Subservicing Agreement; provided,
however, that such subservicing arrangement and the terms of the related
Subservicing Agreement must provide for the servicing of such Mortgage Loan in a
manner consistent with the servicing arrangements contemplated hereunder.
Notwithstanding the provisions of any Subservicing Agreement, any of the
provisions of this Agreement relating to agreements or arrangements between the
Servicer and a Subservicer or reference to actions taken through a Subservicer
or otherwise, the Servicer shall remain obligated and liable to the Depositor,
the Trustee and the Certificateholders for the servicing and administration of
the Mortgage Loans it services in accordance with the provisions of this
Agreement without diminution of such obligation or liability by virtue of such
Subservicing Agreements or arrangements or by virtue of indemnification from the
Subservicer and to the same extent and under the same terms and conditions as if
the Servicer alone were servicing and administering those Mortgage Loans. All
actions of each Subservicer performed pursuant to the related Subservicing
Agreement shall be performed as agent of the Servicer with the same force and
effect as if performed directly by the Servicer.

          (b) For purposes of this Agreement, the Servicer shall be deemed to
have received any collections, recoveries or payments with respect to the
Mortgage Loans it services that are received by a Subservicer regardless of
whether such payments are remitted by the Subservicer to the Servicer.

          (c) As part of its servicing activities hereunder, the Servicer, for
the benefit of the Trustee and the Certificateholders, shall use its best
reasonable efforts to enforce the obligations of each Subservicer engaged by the
Servicer under the related Subservicing Agreement, to the extent that the
non-performance of any such obligation would have a material and adverse effect
on a Mortgage Loan. Such enforcement, including, without limitation, the legal
prosecution of claims, termination of Subservicing Agreements and the pursuit of
other appropriate remedies, shall be in such form and carried out to such an
extent and at such time as the Servicer, in its good faith business judgment,
would require were it the owner of the related Mortgage Loans. The Servicer
shall pay the costs of such enforcement at its own expense, and shall be
reimbursed therefor only (i) from a general recovery resulting from such
enforcement to the extent, if any,

                                      -39-

<PAGE>

that such recovery exceeds all amounts due in respect of the related Mortgage
Loan or (ii) from a specific recovery of costs, expenses or attorneys fees
against the party against whom such enforcement is directed.

          (d) Any Subservicing Agreement entered into by the Servicer shall
provide that it may be assumed or terminated by the Trustee, if the Trustee has
assumed the duties of the Servicer, or any successor Servicer, at the Trustee's
or successor Servicer's option, as applicable, without cost or obligation to the
assuming or terminating party or the Trust Estate, upon the assumption by such
party of the obligations of the Servicer pursuant to Section 8.05.

          Any Subservicing Agreement, and any other transactions or services
relating to the Mortgage Loans involving a Subservicer, shall be deemed to be
between the Servicer and such Subservicer alone, and the Trustee and the
Certificateholders shall not be deemed parties thereto and shall have no claims
or rights of action against, rights, obligations, duties or liabilities to or
with respect to the Subservicer or its officers, directors or employees, except
as set forth in Section 3.01.

          Section 3.03 Fidelity Bond; Errors and Omissions Insurance.

          The Servicer shall maintain, at its own expense, a blanket fidelity
bond and an errors and omissions insurance policy, with broad coverage on all
officers, employees or other persons acting in any capacity requiring such
persons to handle funds, money, documents or papers relating to the Mortgage
Loans it services. These policies must insure the Servicer against losses
resulting from dishonest or fraudulent acts committed by the Servicer's
personnel, any employees of outside firms that provide data processing services
for the Servicer, and temporary contract employees or student interns. Such
fidelity bond shall also protect and insure the Servicer against losses in
connection with the release or satisfaction of a Mortgage Loan without having
obtained payment in full of the indebtedness secured thereby. No provision of
this Section 3.03 requiring such fidelity bond and errors and omissions
insurance shall diminish or relieve the Servicer from its duties and obligations
as set forth in this Agreement. The minimum coverage under any such bond and
insurance policy shall be at least equal to the corresponding amounts required
by FNMA in the FNMA Servicing Guide or by FHLMC in the FHLMC Sellers' &
Servicers' Guide, as amended or restated from time to time, or in an amount as
may be permitted to the Servicer by express waiver of FNMA or FHLMC.

          Section 3.04 Access to Certain Documentation.

          The Servicer shall provide to the OTS and the FDIC and to comparable
regulatory authorities supervising Holders of Subordinate Certificates and the
examiners and supervisory agents of the OTS, the FDIC and such other
authorities, access to the documentation required by applicable regulations of
the OTS and the FDIC with respect to the Mortgage Loans. Such access shall be
afforded without charge, but only upon reasonable and prior written request and
during normal business hours at the offices designated by the Servicer. Nothing
in this Section 3.04 shall limit the obligation of the Servicer to observe any
applicable law and the failure of the Servicer to provide access as provided in
this Section 3.04 as a result of such obligation shall not constitute a breach
of this Section 3.04.

          Section 3.05 Maintenance of Primary Mortgage Insurance Policy; Claims.

          With respect to each Mortgage Loan with a Loan-to-Value Ratio in
excess of 80% or such other Loan-to-Value Ratio as may be required by law, the
Servicer responsible for servicing such Mortgage Loan shall, without any cost to
the Trust Estate, maintain or cause the Mortgagor to maintain in full force and
effect a Primary Insurance Policy insuring that portion of the Mortgage Loan in
excess of a percentage in conformity with FNMA requirements. The Servicer shall
pay or shall cause the Mortgagor to pay the premium thereon on a timely basis,
at least until the Loan-to-Value Ratio of such Mortgage Loan is reduced to 80%
or such other Loan-to-Value Ratio as may be required by law. If such Primary
Insurance Policy is terminated, the Servicer shall obtain from another insurer a
comparable replacement policy, with a total coverage equal to the remaining
coverage of such terminated Primary Insurance Policy. If the insurer shall cease
to be an insurer acceptable to FNMA, the Servicer shall notify the Trustee in
writing, it being understood that the Servicer shall not have any responsibility
or liability for any failure to recover under the Primary Insurance Policy for
such reason. If the Servicer determines that recoveries under the Primary
Insurance Policy are jeopardized by the financial condition of the insurer, the
Servicer shall obtain from another insurer which meets the requirements of this
Section 3.05 a replacement insurance policy. The Servicer shall not take any
action that would result in noncoverage under any applicable Primary Insurance
Policy of any loss that, but for the actions of the Servicer, would have been
covered thereunder. In connection with any assumption or substitution agreement
entered into or to be entered into pursuant to Section 3.13, the Servicer shall
promptly notify the insurer under the related Primary Insurance Policy, if any,
of such assumption or substitution of liability in accordance with the terms of
such Primary Insurance Policy and shall take all actions which may be required
by such insurer as a condition to the continuation of coverage under such
Primary Insurance Policy. If such Primary Insurance Policy is terminated as a
result of such assumption or substitution of liability, the Servicer shall
obtain a replacement Primary Insurance Policy as provided above.

          In connection with its activities as servicer, the Servicer agrees to
prepare and present, on behalf of itself, the Trustee and the
Certificateholders, claims to the insurer under any Primary Insurance Policy in
a timely fashion in accordance with the terms of such Primary Insurance Policy
and, in this regard, to take such action as shall be necessary to permit
recovery under any Primary Insurance Policy respecting a defaulted Mortgage
Loan. Pursuant to Section 3.09(a), any amounts collected by the Servicer under
any Primary Insurance Policy shall be deposited in the related Escrow Account,
subject to withdrawal pursuant to Section 3.09(b).

          The Servicer will comply with all provisions of applicable state and
federal law relating to the cancellation of, or collection of premiums with
respect to, Primary Mortgage Insurance, including, but not limited to, the
provisions of the Homeowners Protection Act of 1998, and all regulations
promulgated thereunder, as amended from time to time.

          Section 3.06 Rights of the Depositor and the Trustee in Respect of the
Servicer.

          The Depositor may, but is not obligated to, enforce the obligations of
the Servicer hereunder and may, but is not obligated to, perform, or cause a
designee to perform, any defaulted obligation of the Servicer hereunder and in
connection with any such defaulted obligation to exercise the related rights of
the Servicer hereunder; provided that the Servicer shall

                                      -41-

<PAGE>

not be relieved of any of its obligations hereunder by virtue of such
performance by the Depositor or its designee. Neither the Trustee nor the
Depositor shall have any responsibility or liability for any action or failure
to act by the Servicer nor shall the Trustee or the Depositor be obligated to
supervise the performance of the Servicer hereunder or otherwise.

          Any Subservicing Agreement that may be entered into and any
transactions or services relating to the Mortgage Loans involving a Subservicer
in its capacity as such shall be deemed to be between the Subservicer and the
Servicer alone, and the Trustee and Certificateholders shall not be deemed
parties thereto and shall have no claims, rights, obligations, duties or
liabilities with respect to the Subservicer except as set forth in Section 3.07.
The Servicer shall be solely liable for all fees owed by it to any Subservicer,
irrespective of whether the Servicer's compensation pursuant to this Agreement
is sufficient to pay such fees.

          Section 3.07 Trustee to Act as Servicer.

          If the Servicer shall for any reason no longer be the Servicer
hereunder (including by reason of an Event of Default), the Trustee shall
thereupon assume, if it so elects, or shall appoint a successor Servicer to
assume, all of the rights and obligations of the Servicer hereunder arising
thereafter (except that the Trustee shall not be (a) liable for losses of the
Servicer pursuant to Section 3.12 or any acts or omissions of the predecessor
Servicer hereunder, (b) obligated to make Advances if it is prohibited from
doing so by applicable law or (c) deemed to have made any representations and
warranties of the Servicer hereunder). Any such assumption shall be subject to
Section 7.02. If the Servicer shall for any reason no longer be the Servicer
(including by reason of any Event of Default), the Trustee or the successor
Servicer may elect to succeed to any rights and obligations of the Servicer
under each Subservicing Agreement or may terminate each Subservicing Agreement.
If it has elected to assume the Subservicing Agreement, the Trustee or the
successor Servicer shall be deemed to have assumed all of the Servicer's
interest therein and to have replaced the Servicer as a party to any
Subservicing Agreement entered into by the Servicer as contemplated by Section
3.02 to the same extent as if the Subservicing Agreement had been assigned to
the assuming party except that the Servicer shall not be relieved of any
liability or obligations under any such Subservicing Agreement.

          The Servicer that is no longer the Servicer hereunder shall, upon
request of the Trustee, but at the expense of the Servicer, deliver to the
assuming party all documents and records relating to each Subservicing Agreement
or substitute servicing agreement and the Mortgage Loans then being serviced
thereunder and an accounting of amounts collected or held by it and otherwise
use its best efforts to effect the orderly and efficient transfer of such
substitute Subservicing Agreement to the assuming party.

          Section 3.08 Collection of Mortgage Loan Payments; Servicer Custodial
Account; Certificate Account; and Upper-Tier Certificate Account.

          (a) Continuously from the date hereof until the principal and interest
on all Mortgage Loans are paid in full, the Servicer will proceed diligently, in
accordance with this Agreement, to collect all payments due under each of the
Mortgage Loans it services when the same shall become due and payable. Further,
the Servicer will in accordance with all applicable law and Customary Servicing
Procedures ascertain and estimate taxes, assessments, fire and

                                      -42-

<PAGE>

hazard insurance premiums, mortgage insurance premiums and all other charges
with respect to the Mortgage Loans it services that, as provided in any
Mortgage, will become due and payable to the end that the installments payable
by the Mortgagors will be sufficient to pay such charges as and when they become
due and payable. Consistent with the foregoing, the Servicer may in its
discretion (i) waive any late payment charge or any prepayment charge or penalty
interest in connection with the prepayment of a Mortgage Loan it services and
(ii) extend the due dates for payments due on a Mortgage Note for a period not
greater than 120 days; provided, however, that the Servicer cannot extend the
maturity of any such Mortgage Loan past the date on which the final payment is
due on the latest maturing Mortgage Loan as of the Cut-Off Date. In the event of
any such arrangement, the Servicer shall make Periodic Advances on the related
Mortgage Loan in accordance with the provisions of Section 3.20 during the
scheduled period in accordance with the amortization schedule of such Mortgage
Loan without modification thereof by reason of such arrangements. The Servicer
shall not be required to institute or join in litigation with respect to
collection of any payment (whether under a Mortgage, Mortgage Note or otherwise
or against any public or governmental authority with respect to a taking or
condemnation) if it reasonably believes that enforcing the provision of the
Mortgage or other instrument pursuant to which such payment is required is
prohibited by applicable law.

          (b) The Servicer shall establish and maintain the Servicer Custodial
Account. The Servicer shall deposit or cause to be deposited into the Servicer
Custodial Account, all on a daily basis within one Business Day of receipt,
except as otherwise specifically provided herein, the following payments and
collections remitted by Subservicers or received by the Servicer in respect of
the Mortgage Loans subsequent to the Cut-Off Date (other than in respect of
principal and interest due on the Mortgage Loans on or before the Cut-Off Date)
and the following amounts required to be deposited hereunder with respect to the
Mortgage Loans it services:

          (i)     all payments on account of principal of the Mortgage Loans,
including Principal Prepayments;

          (ii)    all payments on account of interest on the Mortgage Loans, net
of the Servicing Fee;

          (iii)   (A) all Insurance Proceeds and Liquidation Proceeds, other
than Insurance Proceeds to be (1) applied to the restoration or repair of the
Mortgaged Property, (2) released to the Mortgagor in accordance with Customary
Servicing Procedures or (3) required to be deposited to an Escrow Account
pursuant to Section 3.09(a) and (B) any Insurance Proceeds released from an
Escrow Account pursuant to Section 3.09(b)(iv);

          (iv)    any amount required to be deposited by the Servicer pursuant
to Section 3.08(d) in connection with any losses on Permitted Investments with
respect to the Servicer Custodial Account;

          (v)     any amounts required to be deposited by the Servicer pursuant
to Section 3.14;

                                      -43-

<PAGE>

          (vi)    all Repurchase Prices and all Substitution Adjustment Amounts
received by the Servicer;

          (vii)   Periodic Advances made by the Servicer pursuant to Section
3.20 and any payments of Compensating Interest; and

          (viii)  any other amounts required to be deposited hereunder.

          The foregoing requirements for deposits to the Servicer Custodial
Account by the Servicer shall be exclusive, it being understood and agreed that,
without limiting the generality of the foregoing, payments in the nature of
prepayment penalties, late payment charges or assumption fees, if collected,
need not be deposited by the Servicer. If the Servicer shall deposit in the
Servicer Custodial Account any amount not required to be deposited, it may at
any time withdraw or direct the institution maintaining the Servicer Custodial
Account to withdraw such amount from the Servicer Custodial Account, any
provision herein to the contrary notwithstanding. The Servicer Custodial Account
may contain funds that belong to one or more trust funds created for mortgage
pass-through certificates of other series and may contain other funds respecting
payments on mortgage loans belonging to the Servicer or serviced by the Servicer
on behalf of others. Notwithstanding such commingling of funds, the Servicer
shall keep records that accurately reflect the funds on deposit in the Servicer
Custodial Account that have been identified by it as being attributable to the
Mortgage Loans it services. The Servicer shall maintain adequate records with
respect to all withdrawals made pursuant to this Section 3.08. All funds
required to be deposited in the Servicer Custodial Account shall be held in
trust for the Certificateholders until withdrawn in accordance with Section
3.11.

          (c) The Trustee shall establish and maintain, on behalf of the
Certificateholders, the Certificate Account. The Trustee shall, promptly upon
receipt, deposit in the Certificate Account and retain therein the following:

          (i)     the aggregate amount remitted by the Servicer to the Trustee
pursuant to Section 3.11(a)(viii);

          (ii)    any amount paid by the Trustee pursuant to Section 3.08(d) in
connection with any losses on Permitted Investments with respect to the
Certificate Account; and

          (iii)   any other amounts deposited hereunder which are required to be
deposited in the Certificate Account.

          If the Servicer shall remit any amount not required to be remitted, it
may at any time direct the Trustee to withdraw such amount from the Certificate
Account, any provision herein to the contrary notwithstanding. Such direction
may be accomplished by delivering an Officer's Certificate to the Trustee which
describes the amounts deposited in error in the Certificate Account. All funds
required to be deposited in the Certificate Account shall be held by the Trustee
in trust for the Certificateholders until disbursed in accordance with this
Agreement or withdrawn in accordance with Section 3.11. In no event shall the
Trustee incur liability for withdrawals from the Certificate Account at the

          (d) Each institution at which the Servicer Custodial Account or the
Certificate Account is maintained shall invest the funds therein as directed in
writing by the Servicer in Permitted Investments, which shall mature not later
than (i) in the case of the Servicer Custodial Account, the Business Day next
preceding the related Remittance Date (except that if such Permitted Investment
is an obligation of the institution that maintains such account, then such
Permitted Investment shall mature not later than such Remittance Date) and (ii)
in the case of the Certificate Account, the Business Day next preceding the
Distribution Date (except that if such Permitted Investment is an obligation of
the institution that maintains such account, then such Permitted Investment
shall mature not later than such Distribution Date) and, in each case, shall not
be sold or disposed of prior to its maturity. All such Permitted Investments
shall be made in the name of the Trustee, for the benefit of the
Certificateholders. All income or gain (net of any losses) realized from any
such investment of funds on deposit in the Servicer Custodial Account shall be
for the benefit of the Servicer as servicing compensation and shall be retained
by it monthly as provided herein. All income or gain (net of any losses)
realized from any such investment of funds on deposit in the Certificate Account
shall be for the benefit of the Trustee as additional compensation and shall be
retained by it monthly as provided herein. The amount of any losses realized in
the Servicer Custodial Account or the Certificate Account incurred in any such
account in respect of any such investments shall promptly be deposited by the
Servicer in the Servicer Custodial Account or by the Trustee in the Certificate
Account, as applicable.

          (e) The Servicer shall give notice to the Trustee of any proposed
change of the location of the Servicer Custodial Account maintained by the
Servicer not later than 30 days and not more than 45 days prior to any change
thereof. The Trustee shall give notice to the Servicer, each Rating Agency and
the Depositor of any proposed change of the location of the Certificate Account
not later than 30 days and not more than 45 days prior to any change thereof.
The creation of the Servicer Custodial Account shall be evidenced by a
certification substantially in the form of Exhibit F hereto. A copy of such
certification shall be furnished to the Trustee.

          (f) The Trustee shall establish and maintain the Upper-Tier
Certificate Account. On each Distribution Date (other than the Final
Distribution Date, if such Final Distribution Date is in connection with a
purchase of the assets of the Trust Estate by the Depositor), the Trustee shall,
from funds available on deposit in the Certificate Account, deposit, in
immediately available funds, by wire transfer or otherwise, into the Upper-Tier
Certificate Account, the Lower-Tier Distribution Amount.

          Section 3.09 Collection of Taxes, Assessments and Similar Items;
Escrow Accounts.

          (a) To the extent required by the related Mortgage Note and not
violative of current law, the Servicer shall segregate and hold all funds
collected and received pursuant to each Mortgage Loan which constitute Escrow
Payments in trust separate and apart from any of its own funds and general
assets and for such purpose shall establish and maintain one or more escrow
accounts (collectively, the "Escrow Account"), titled "[Insert name of
Servicer], in trust for registered holders of BA Residential Securities, Inc.
Mortgage Pass-Through Certificates, Series 200 - and various Mortgagors." The
Escrow Account shall be established with a commercial bank, a savings bank or a
savings and loan association that meets the guidelines set forth by FNMA or
FHLMC as an eligible institution for escrow accounts and which is a member

                                      -45-

<PAGE>

of the Automated Clearing House. In any case, the Escrow Account shall be
insured by the FDIC to the fullest extent permitted by law. The Servicer shall
deposit in the appropriate Escrow Account on a daily basis, and retain therein:
(i) all Escrow Payments collected on account of the Mortgage Loans, (ii) all
amounts representing proceeds of any hazard insurance policy which are to be
applied to the restoration or repair of any related Mortgaged Property and (iii)
all amounts representing proceeds of any Primary Insurance Policy. Nothing
herein shall require the Servicer to compel a Mortgagor to establish an Escrow
Account in violation of applicable law.

          (b) Withdrawals of amounts so collected from the Escrow Accounts may
be made by the Servicer only (i) to effect timely payment of taxes, assessments,
mortgage insurance premiums, fire and hazard insurance premiums, condominium or
PUD association dues, or comparable items constituting Escrow Payments for the
related Mortgage, (ii) to reimburse the Servicer out of related Escrow Payments
made with respect to a Mortgage Loan for any Servicing Advance made by the
Servicer pursuant to Section 3.09(c) with respect to such Mortgage Loan, (iii)
to refund to any Mortgagor any sums determined to be overages, (iv) for transfer
to the Servicer Custodial Account upon default of a Mortgagor or in accordance
with the terms of the related Mortgage Loan and if permitted by applicable law,
(v) for application to restore or repair the Mortgaged Property, (vi) to pay to
the Mortgagor, to the extent required by law, any interest paid on the funds
deposited in the Escrow Account, (vii) to pay to itself any interest earned on
funds deposited in the Escrow Account (and not required to be paid to the
Mortgagor), (viii) to the extent permitted under the terms of the related
Mortgage Note and applicable law, to pay late fees with respect to any Monthly
Payment which is received after the applicable grace period, (ix) to withdraw
suspense payments that are deposited into the Escrow Account, (x) to withdraw
any amounts inadvertently deposited in the Escrow Account or (xi) to clear and
terminate the Escrow Account upon the termination of this Agreement in
accordance with Section 10.01. Any Escrow Account shall not be a part of the
Trust Estate.

          (c) With respect to each Mortgage Loan, the Servicer shall maintain
accurate records reflecting the status of taxes, assessments and other charges
which are or may become a lien upon the Mortgaged Property and the status of
Primary Insurance Policy premiums and fire and hazard insurance coverage. The
Servicer shall obtain, from time to time, all bills for the payment of such
charges (including renewal premiums) and shall effect payment thereof prior to
the applicable penalty or termination date and at a time appropriate for
securing maximum discounts allowable, employing for such purpose deposits of the
Mortgagor in the Escrow Account, if any, which shall have been estimated and
accumulated by the Servicer in amounts sufficient for such purposes, as allowed
under the terms of the Mortgage. To the extent that a Mortgage does not provide
for Escrow Payments, the Servicer shall determine that any such payments are
made by the Mortgagor. The Servicer assumes full responsibility for the timely
payment of all such bills and shall effect timely payments of all such bills
irrespective of each Mortgagor's faithful performance in the payment of same or
the making of the Escrow Payments. The Servicer shall advance any such payments
that are not timely paid, but the Servicer shall be required so to advance only
to the extent that such Servicing Advances, in the good faith judgment of the
Servicer, will be recoverable by the Servicer out of Insurance Proceeds,
Liquidation Proceeds or otherwise.

          Section 3.10 Access to Certain Documentation and Information Regarding
the Mortgage Loans.

                                      -46-

<PAGE>

          The Servicer shall afford the Trustee reasonable access to all records
and documentation regarding the Mortgage Loans and all accounts, insurance
information and other matters relating to this Agreement, such access being
afforded without charge, but only upon reasonable request and during normal
business hours at the office designated by the Servicer.

          Upon reasonable advance notice in writing, the Servicer will provide
to each Certificateholder which is a savings and loan association, bank or
insurance company certain reports and reasonable access to information and
documentation regarding the Mortgage Loans sufficient to permit such
Certificateholder to comply with applicable regulations of the OTS or other
regulatory authorities with respect to investment in the Certificates; provided
that the Servicer shall be entitled to be reimbursed by each such
Certificateholder for actual expenses incurred by the Servicer in providing such
reports and access.

          Section 3.11 Permitted Withdrawals from the Servicer Custodial
Account; Certificate Account and Upper-Tier Certificate Account.

          (a) The Servicer may from time to time make withdrawals from the
Servicer Custodial Account, for the following purposes:

          (i)     to pay to the Servicer (to the extent not previously
     retained), the servicing compensation to which it is entitled pursuant to
     Section 3.17, and to pay to the Servicer, as additional servicing
     compensation, earnings on or investment income with respect to funds in or
     credited to the Servicer Custodial Account;

          (ii)    to reimburse the Servicer for unreimbursed Advances made by
     it, such right of reimbursement pursuant to this clause (ii) being limited
     to amounts received on the Mortgage Loan(s) in respect of which any such
     Advance was made;

          (iii)   to reimburse the Servicer for any Nonrecoverable Advance
     previously made;

          (iv)    to reimburse the Servicer for Insured Expenses from the
     related Insurance Proceeds;

          (v)     to pay to the purchaser, with respect to each Mortgage Loan or
     REO Property that has been purchased pursuant to Section 2.02 or 2.04, all
     amounts received thereon after the date of such purchase;

          (vi)    to reimburse the Servicer or the Depositor for expenses
     incurred by any of them and reimbursable pursuant to Section 7.03;

          (vii)   to withdraw any amount deposited in the Servicer Custodial
     Account and not required to be deposited therein;

          (viii)  on or prior to the Remittance Date, to withdraw an amount
     equal to the related Pool Distribution Amount, the related Trustee Fee and
     any other amounts due to the Trustee under this Agreement for such
     Distribution Date, to the extent on deposit, and

                                      -47-

<PAGE>

     remit such amount in immediately available funds to the Trustee for deposit
     in the Certificate Account; and

          (ix)    to clear and terminate the Servicer Custodial Account upon
     termination of this Agreement pursuant to Section 10.01.

          The Servicer shall keep and maintain separate accounting, on a
Mortgage Loan by Mortgage Loan basis, for the purpose of justifying any
withdrawal from the Servicer Custodial Account pursuant to clauses (i), (ii),
(iv) and (v). Prior to making any withdrawal from the Servicer Custodial Account
pursuant to clause (iii), the Servicer shall deliver to the Trustee an Officer's
Certificate of a Servicing Officer indicating the amount of any previous Advance
determined by the Servicer to be a Nonrecoverable Advance and identifying the
related Mortgage Loan(s) and their respective portions of such Nonrecoverable
Advance.

          (b) The Trustee shall withdraw funds from the Certificate Account for
distributions to Certificateholders in the manner specified in this Agreement.
In addition, the Trustee may from time to time make withdrawals from the
Certificate Account for the following purposes:

          (i)     to pay to itself the Trustee Fee and any other amounts due to
     the Trustee under this Agreement for the related Distribution Date;

          (ii)    to pay to itself as additional compensation earnings on or
     investment income with respect to funds in the Certificate Account;

          (iii)   to withdraw and return to the Servicer any amount deposited in
     the Certificate Account and not required to be deposited therein; and

          (iv)    to clear and terminate the Certificate Account upon
     termination of the Agreement pursuant to Section 10.01.

          (c) Notwithstanding anything herein to the contrary, the Regular
Certificates and the Class A-R Certificate shall not receive distributions
directly from the Certificate Account. On each Distribution Date, funds on
deposit in the Upper-Tier Certificate Account shall be used to make payments on
the Regular Certificates and the Class A-R Certificate as provided in Sections
5.01 and 5.02. The Upper-Tier Certificate Account shall be cleared and
terminated upon termination of this Agreement pursuant to Section 10.01.

          Section 3.12 Maintenance of Hazard Insurance.

          The Servicer shall cause to be maintained for each Mortgage Loan, fire
and hazard insurance with extended coverage customary in the area where the
Mortgaged Property is located in an amount which is at least equal to the lesser
of (a) the full insurable value of the Mortgaged Property or (b) the greater of
(i) the outstanding principal balance owing on the Mortgage Loan and (ii) an
amount such that the proceeds of such insurance shall be sufficient to avoid the
application to the Mortgagor or loss payee of any coinsurance clause under the
policy. If the Mortgaged Property is in an area identified in the Federal
Register by the Federal Emergency Management Agency as having special flood
hazards (and such flood insurance has

                                      -48-

<PAGE>

been made available) the Servicer will cause to be maintained a flood insurance
policy meeting the requirements of the current guidelines of the Federal
Insurance Administration and the requirements of FNMA or FHLMC. The Servicer
shall also maintain on REO Property, fire and hazard insurance with extended
coverage in an amount which is at least equal to the maximum insurable value of
the improvements which are a part of such property, liability insurance and, to
the extent required, flood insurance in an amount required above. Any amounts
collected by the Servicer under any such policies (other than amounts to be
deposited in an Escrow Account and applied to the restoration or repair of the
property subject to the related Mortgage or property acquired in liquidation of
the Mortgage Loan, or to be released to the Mortgagor in accordance with
Customary Servicing Procedures) shall be deposited in the Servicer Custodial
Account, subject to withdrawal pursuant to Section 3.11(a). It is understood and
agreed that no earthquake or other additional insurance need be required by the
Servicer of any Mortgagor or maintained on REO Property, other than pursuant to
such applicable laws and regulations as shall at any time be in force and as
shall require such additional insurance. All policies required hereunder shall
be endorsed with standard mortgagee clauses with loss payable to the Servicer,
and shall provide for at least 30 days prior written notice of any cancellation,
reduction in amount or material change in coverage to the Servicer.

          The hazard insurance policies for each Mortgage Loan secured by a unit
in a condominium development or planned unit development shall be maintained
with respect to such Mortgage Loan and the related development in a manner which
is consistent with FNMA requirements.

          Notwithstanding the foregoing, the Servicer may maintain a blanket
policy insuring against hazard losses on all of the Mortgaged Properties
relating to the Mortgage Loans in lieu of maintaining the required hazard
insurance policies for each Mortgage Loan and may maintain a blanket policy
insuring against special flood hazards in lieu of maintaining any required flood
insurance. Any such blanket policies shall (A) be consistent with prudent
industry standards, (B) name the Servicer as loss payee, (C) provide coverage in
an amount equal to the aggregate unpaid principal balance on the related
Mortgage Loans without co-insurance, and (D) otherwise comply with the
requirements of this Section 3.12. Any such blanket policy may contain a
deductible clause; provided that if any Mortgaged Property is not covered by a
separate policy otherwise complying with this Section 3.12 and a loss occurs
with respect to such Mortgaged Property which loss would have been covered by
such a policy, the Servicer shall deposit in the Servicer Custodial Account the
difference, if any, between the amount that would have been payable under a
separate policy complying with this Section 3.12 and the amount paid under such
blanket policy.

          Section 3.13 Enforcement of Due-On-Sale Clauses; Assumption
Agreements.

          (a) Except as otherwise provided in this Section 3.13, when any
Mortgaged Property subject to a Mortgage has been conveyed by the Mortgagor, the
Servicer shall use reasonable efforts, to the extent that it has actual
knowledge of such conveyance, to enforce any due-on-sale clause contained in any
Mortgage Note or Mortgage, to the extent permitted under applicable law and
governmental regulations, but only to the extent that such enforcement will not
adversely affect or jeopardize coverage under any Required Insurance Policy.
Notwithstanding the foregoing, the Servicer is not required to exercise such
rights with respect to

                                      -49-

<PAGE>

a Mortgage Loan if the Person to whom the related Mortgaged Property has been
conveyed or is proposed to be conveyed satisfies the terms and conditions
contained in the Mortgage Note and Mortgage related thereto and the consent of
the mortgagee under such Mortgage Note or Mortgage is not otherwise required
under such Mortgage Note or Mortgage as a condition to such transfer. If (i) the
Servicer is prohibited by law from enforcing any such due-on-sale clause, (ii)
coverage under any Required Insurance Policy would be adversely affected, (iii)
the Mortgage Note does not include a due-on-sale clause or (iv) nonenforcement
is otherwise permitted hereunder, the Servicer is authorized, subject to Section
3.13(b), to take or enter into an assumption and modification agreement from or
with the Person to whom such Mortgaged Property has been or is about to be
conveyed, pursuant to which such Person becomes liable under the Mortgage Note
and, unless prohibited by applicable state law, the Mortgagor remains liable
thereon; provided that the Mortgage Loan shall continue to be covered (if so
covered before the Servicer enters such agreement) by the applicable Required
Insurance Policies. The Servicer, subject to Section 3.13(b), is also authorized
with the prior approval of the insurers under any Required Insurance Policies 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.
Notwithstanding the foregoing, the Servicer shall not be deemed to be in default
under this Section 3.13 by reason of any transfer or assumption which the
Servicer reasonably believes it is restricted by law from preventing, for any
reason whatsoever.

          (b) Subject to the Servicer's duty to enforce any due-on-sale clause
to the extent set forth in Section 3.13(a), in any case in which a Mortgaged
Property has been conveyed to a Person by a Mortgagor, and such Person is to
enter into an assumption agreement or modification agreement or supplement to
the Mortgage Note or Mortgage that requires the signature of the Trustee, or if
an instrument of release signed by the Trustee is required releasing the
Mortgagor from liability on the Mortgage Loan, the Servicer shall prepare and
deliver or cause to be prepared and delivered to the Trustee for signature and
shall direct, in writing, the Trustee to execute the assumption agreement with
the Person to whom the Mortgaged Property is to be conveyed and such
modification agreement or supplement to the Mortgage Note or Mortgage or other
instruments as are reasonable or necessary to carry out the terms of the
Mortgage Note or Mortgage or otherwise to comply with any applicable laws
regarding assumptions or the transfer of the Mortgaged Property to such Person.
In no event shall the Trustee incur liability for executing any document under
this Section 3.13 at the direction of the Servicer. In connection with any such
assumption, no material term of the Mortgage Note may be changed. In addition,
the substitute Mortgagor and the Mortgaged Property must be acceptable to the
Servicer in accordance with its underwriting standards as then in effect.
Together with each such substitution, assumption or other agreement or
instrument delivered to the Trustee for execution by it, the Servicer shall
deliver an Officer's Certificate signed by a Servicing Officer stating that the
requirements of this subsection have been met. The Servicer shall notify the
Trustee that any such substitution or assumption agreement has been completed by
forwarding to the Trustee (or at the direction of the Trustee, the Custodian)
the original of such substitution or assumption agreement, which in the case of
the original shall be added to the related Mortgage File and shall, for all
purposes, be considered a part of such Mortgage File to the same extent as all
other documents and instruments constituting a part thereof. Any fee collected
by the Servicer for entering into an assumption or substitution of liability
agreement may be retained by the Servicer as additional master servicing
compensation. Notwithstanding

                                      -50-

<PAGE>

the foregoing, to the extent permissible under applicable law and at the request
of the Servicer, the Trustee shall execute and deliver to the Servicer any
powers of attorney and other documents prepared by the Servicer that are
reasonably necessary or appropriate to enable the Servicer to execute any
assumption agreement or modification agreement required to be executed by the
Trustee under this Section 3.13.

          Section 3.14 Realization Upon Defaulted Mortgage Loans; REO Property.

          (a) The Servicer shall use reasonable efforts to foreclose upon or
otherwise comparably convert the ownership of Mortgaged Properties securing such
of the Mortgage Loans as come into and continue in default and as to which no
satisfactory arrangements can be made for collection of delinquent payments. In
connection with such foreclosure or other conversion, the Servicer shall follow
Customary Servicing Procedures and shall meet the requirements of the insurer
under any Required Insurance Policy; provided, however, that the Servicer may
enter into a special servicing agreement with an unaffiliated Holder of 100%
Percentage Interest of a Class of Class B Certificates or a holder of a class of
securities representing interests in the Class B Certificates alone or together
with other subordinated mortgage pass-through certificates. Such agreement shall
be substantially in the form attached hereto as Exhibit K or subject to each
Rating Agency's acknowledgment that the ratings of the Certificates in effect
immediately prior to the entering into such agreement would not be qualified,
downgraded or withdrawn and the Certificates would not be placed on credit
review status (except for possible upgrading) as a result of such agreement. Any
such agreement may contain provisions whereby such holder may instruct the
Servicer to commence or delay foreclosure proceedings with respect to delinquent
Mortgage Loans and will contain provisions for the deposit of cash by the holder
that would be available for distribution to Certificateholders if Liquidation
Proceeds are less than they otherwise may have been had the Servicer acted in
accordance with its normal procedures. Notwithstanding the foregoing, the
Servicer shall not be required to expend its own funds in connection with any
foreclosure or towards the restoration of any Mortgaged Property unless it shall
determine (i) that such restoration and/or foreclosure will increase the
proceeds of liquidation of the Mortgage Loan after reimbursement to itself of
such expenses and (ii) that such expenses will be recoverable to it through
proceeds of the liquidation of the Mortgage Loan (respecting which it shall have
priority for purposes of withdrawals from the Servicer Custodial Account). Any
such expenditures shall constitute Servicing Advances for purposes of this
Agreement.

          The decision of the Servicer to foreclose on a defaulted Mortgage Loan
shall be subject to a determination by the Servicer that the proceeds of such
foreclosure would exceed the costs and expenses of bringing such a proceeding.

          With respect to any REO Property, the deed or certificate of sale
shall be taken in the name of the Trustee for the benefit of the
Certificateholders, or its nominee, on behalf of the Certificateholders. The
Trustee's name shall be placed on the title to such REO Property solely as the
Trustee hereunder and not in its individual capacity. The Servicer shall ensure
that the title to such REO Property references this Agreement and the Trustee's
capacity hereunder. Pursuant to its efforts to sell such REO Property, the
Servicer shall either itself or through an agent selected by the Servicer
manage, conserve, protect and operate such REO Property in the same manner that
it manages, conserves, protects and operates other foreclosed property for its

                                      -51-

<PAGE>

own account and in the same manner that similar property in the same locality as
the REO Property is managed. Incident to its conservation and protection of the
interests of the Certificateholders, the Servicer may rent the same, or any part
thereof, as the Servicer deems to be in the best interest of the
Certificateholders for the period prior to the sale of such REO Property. The
Servicer shall prepare for and deliver to the Trustee a statement with respect
to each REO Property that has been rented, if any, showing the aggregate rental
income received and all expenses incurred in connection with the management and
maintenance of such REO Property at such times as is necessary to enable the
Trustee to comply with the reporting requirements of the REMIC Provisions;
provided, however, that the Servicer shall have no duty to rent any REO Property
on behalf of the Trust. The net monthly rental income, if any, from such REO
Property shall be deposited in the Servicer Custodial Account no later than the
close of business on each Determination Date. The Servicer shall perform, with
respect to the Mortgage Loans, the tax reporting and withholding required by
Sections 1445 and 6050J of the Code with respect to foreclosures and
abandonments, the tax reporting required by Section 6050H of the Code with
respect to the receipt of mortgage interest from individuals and, if required by
Section 6050P of the Code with respect to the cancellation of indebtedness by
certain financial entities, by preparing such tax and information returns as may
be required, in the form required. The Servicer shall deliver copies of such
reports to the Trustee.

          If the Trust acquires any Mortgaged Property as described above or
otherwise in connection with a default or a default which is reasonably
foreseeable on a Mortgage Loan, the Servicer shall dispose of such Mortgaged
Property prior to the end of the third calendar year following the year of its
acquisition by the Trust (such period, the "REO Disposition Period") unless (A)
the Trustee shall have been supplied by the Servicer with an Opinion of Counsel
to the effect that the holding by the Trust of such Mortgaged Property
subsequent to the REO Disposition Period will not result in the imposition of
taxes on "prohibited transactions" (as defined in Section 860F of the Code) on
either the Upper-Tier REMIC or the Lower-Tier REMIC or cause either REMIC to
fail to qualify as a REMIC at any time that any Certificates are outstanding, or
(B) the Trustee (at the Servicer's expense) or the Servicer shall have applied
for, prior to the expiration of the REO Disposition Period, an extension of the
REO Disposition Period in the manner contemplated by Section 856(e)(3) of the
Code. If such an Opinion of Counsel is provided or such an exemption is
obtained, the Trust may continue to hold such Mortgaged Property (subject to any
conditions contained in such Opinion of Counsel) for the applicable period.
Notwithstanding any other provision of this Agreement, no Mortgaged Property
acquired by the Trust shall be rented (or allowed to continue to be rented) or
otherwise used for the production of income by or on behalf of the Trust in such
a manner or pursuant to any terms that would (i) cause such Mortgaged Property
to fail to qualify as "foreclosure property" within the meaning of Section
860G(a)(8) of the Code or (ii) subject either REMIC to the imposition of any
federal, state or local income taxes on the income earned from such Mortgaged
Property under Section 860G(c) of the Code or otherwise, unless the Servicer has
agreed to indemnify and hold harmless the Trust with respect to the imposition
of any such taxes. The Servicer shall identify to the Trustee any Mortgaged
Property relating to a Mortgage Loan held by the Trust for 30 months for which
no plans to dispose of such Mortgaged Property by the Servicer have been made.
After delivery of such identification, the Servicer shall proceed to dispose of
any such Mortgaged Property by holding a commercially reasonable auction for
such property.

                                      -52-

<PAGE>

          The income earned from the management of any REO Properties, net of
reimbursement to the Servicer for expenses incurred (including any property or
other taxes) in connection with such management and net of unreimbursed
Servicing Fees, Periodic Advances and Servicing Advances, shall be applied to
the payment of principal of and interest on the related defaulted Mortgage Loans
(solely for the purposes of allocating principal and interest, interest shall be
treated as accruing as though such Mortgage Loans were still current) and all
such income shall be deemed, for all purposes in this Agreement, to be payments
on account of principal and interest on the related Mortgage Notes and shall be
deposited into the Servicer Custodial Account. To the extent the net income
received during any calendar month is in excess of the amount attributable to
amortizing principal and accrued interest at the related Mortgage Interest Rate
on the related Mortgage Loan for such calendar month, such excess shall be
considered to be a partial prepayment of principal of the related Mortgage Loan.

          The proceeds from any liquidation of a Mortgage Loan, as well as any
income from an REO Property, will be applied in the following order of priority:
first, to reimburse the Servicer for any related unreimbursed Servicing Advances
and Servicing Fees; second, to reimburse the Servicer for any unreimbursed
Periodic Advances and to reimburse the Servicer Custodial Account for any
Nonrecoverable Advances (or portions thereof) that were previously withdrawn by
the Servicer pursuant to Section 3.11(a)(iii) that related to such Mortgage
Loan; third, to accrued and unpaid interest (to the extent no Periodic Advance
has been made for such amount or any such Periodic Advance has been reimbursed)
on the Mortgage Loan or related REO Property, at the Mortgage Rate to the Due
Date occurring in the month in which such amounts are required to be
distributed; and fourth, as a recovery of principal of the Mortgage Loan. Excess
Proceeds, if any, from the liquidation of a Liquidated Mortgage Loan will be
retained by the Servicer as additional servicing compensation pursuant to
Section 3.17.

          (b) The Servicer shall promptly notify the Depositor of any Mortgage
Loan which comes into default. The Depositor shall be entitled, at its option,
to repurchase (i) any such defaulted Mortgage Loan from the Trust Estate if (a)
in the Depositor's judgment, the default is not likely to be cured by the
Mortgagor and (b) such Mortgage Loan is 180 days or more delinquent or (ii) any
Mortgage Loan in the Trust Estate which pursuant to Section 4(b) of the Mortgage
Loan Purchase Agreement the Seller requests the Depositor to repurchase and to
sell to the Seller to facilitate the exercise of the Seller's rights against the
originator or prior holder of such Mortgage Loan. The purchase price for any
such Mortgage Loan shall be 100% of the unpaid principal balance of such
Mortgage Loan plus accrued interest thereon at the Mortgage Interest Rate (less
the Servicing Fee Rate for such Mortgage Loan) through the last day of the month
in which such repurchase occurs. Upon the receipt of such purchase price, the
Servicer shall provide to the Trustee the notification required by Section 3.15
and the Trustee or the Custodian shall promptly release to the Depositor the
Mortgage File relating to the Mortgage Loan being repurchased.

          Section 3.15 Trustee to Cooperate; Release of Mortgage Files.

          Upon the payment in full of any Mortgage Loan, or the receipt by the
Servicer of a notification that payment in full will be escrowed in a manner
customary for such purposes, the Servicer will immediately notify the Trustee
(or, at the direction of the Trustee, the Custodian) by delivering, or causing
to be delivered, two copies (one of which will be returned to the

                                      -53-

Servicer with the Mortgage File) of a Request for Release (which may be
delivered in an electronic format acceptable to the Trustee and the Servicer).
Upon receipt of such request, the Trustee or the Custodian, as applicable, shall
within seven Business Days release the related Mortgage File to the Servicer.
The Trustee shall at the Servicer's direction execute and deliver to the
Servicer the request for reconveyance, deed of reconveyance or release or
satisfaction of mortgage or such instrument releasing the lien of the Mortgage,
in each case provided by the Servicer, together with the Mortgage Note with
written evidence of cancellation thereon. If the Mortgage has been recorded in
the name of MERS or its designee, the Servicer shall take all necessary action
to reflect the release of the Mortgage on the records of MERS. Expenses incurred
in connection with any instrument of satisfaction or deed of reconveyance shall
be chargeable to the related Mortgagor. From time to time and as shall be
appropriate for the servicing or foreclosure of any Mortgage Loan, including for
such purpose collection under any policy of flood insurance, any fidelity bond
or errors or omissions policy, or for the purposes of effecting a partial
release of any Mortgaged Property from the lien of the Mortgage or the making of
any corrections to the Mortgage Note or the Mortgage or any of the other
documents included in the Mortgage File, the Trustee or the Custodian, as
applicable, shall, upon delivery to the Trustee (or, at the direction of the
Trustee, the Custodian) of a Request for Release signed by a Servicing Officer,
release the Mortgage File within seven Business Days to the Servicer. Subject to
the further limitations set forth below, the Servicer shall cause the Mortgage
File so released to be returned to the Trustee or the Custodian, as applicable,
when the need therefor by the Servicer no longer exists, unless the Mortgage
Loan is liquidated and the proceeds thereof are deposited in the Servicer
Custodial Account, in which case the Servicer shall deliver to the Trustee or
the Custodian, as applicable, a Request for Release, signed by a Servicing
Officer.

          The Trustee shall execute and deliver to the Servicer any powers of
attorney and other documents prepared by the Servicer that are reasonably
necessary or appropriate to enable the Servicer to carry out its servicing and
administrative duties under this Agreement, upon the request of the Servicer. In
addition, upon prepayment in full of any Mortgage Loan or the receipt of notice
that funds for such purpose have been placed in escrow, the Servicer is
authorized to give, as attorney-in-fact for the Trustee and the mortgagee under
the Mortgage, an instrument of satisfaction (or Assignment of Mortgage without
recourse) regarding the Mortgaged Property relating to such Mortgage Loan, which
instrument of satisfaction or Assignment of Mortgage, as the case may be, shall
be delivered to the Person entitled thereto against receipt of the prepayment in
full. If the Mortgage is registered in the name of MERS or its designee, the
Servicer shall take all necessary action to reflect the release on the records
of MERS. In lieu of executing such satisfaction or Assignment of Mortgage, or if
another document is required to be executed by the Trustee, the Servicer may
deliver or cause to be delivered to the Trustee, for signature, as appropriate,
any court pleadings, requests for trustee's sale or other documents necessary to
effectuate such foreclosure or any legal action brought to obtain judgment
against the Mortgagor on the Mortgage Note or the Mortgage or to obtain a
deficiency judgment or to enforce any other remedies or rights provided by the
Mortgage Note or the Mortgage or otherwise available at law or in equity.

          Section 3.16 Documents, Records and Funds in Possession of the
Servicer to be Held for the Trustee.

                                      -54-

<PAGE>

          The Servicer shall transmit to the Trustee or, at the direction of the
Trustee, the Custodian as required by this Agreement all documents and
instruments in respect of a Mortgage Loan coming into the possession of the
Servicer from time to time and shall account fully to the Trustee for any funds
received by the Servicer or which otherwise are collected by the Servicer as
Liquidation Proceeds or Insurance Proceeds in respect of any Mortgage Loan. The
documents constituting the Servicing File shall be held by the Servicer as
custodian and bailee for the Trustee. All Mortgage Files and funds collected or
held by, or under the control of, the Servicer in respect of any Mortgage Loans,
whether from the collection of principal and interest payments or from
Liquidation Proceeds, including but not limited to, any funds on deposit in the
Servicer Custodial Account, shall be held by the Servicer for and on behalf of
the Trustee and shall be and remain the sole and exclusive property of the
Trustee, subject to the applicable provisions of this Agreement. The Servicer
also agrees that it shall not knowingly create, incur or subject any Mortgage
File or any funds that are deposited in the Servicer Custodial Account,
Certificate Account or any Escrow Account, or any funds that otherwise are or
may become due or payable to the Trustee for the benefit of the
Certificateholders, to any claim, lien, security interest, judgment, levy, writ
of attachment or other encumbrance created by the Servicer, or assert by legal
action or otherwise any claim or right of setoff against any Mortgage File or
any funds collected on, or in connection with, a Mortgage Loan, except, however,
that the Servicer shall be entitled to set off against and deduct from any such
funds any amounts that are properly due and payable to the Servicer under this
Agreement.

          Section 3.17 Servicing Compensation.

          The Servicer shall be entitled out of each payment of interest on a
Mortgage Loan (or portion thereof) and included in the Trust Estate to retain or
withdraw from the Servicer Custodial Account an amount equal to the Servicing
Fee for such Distribution Date.

          Additional servicing compensation in the form of Excess Proceeds,
prepayment penalties, assumption fees, late payment charges and all income and
gain net of any losses realized from Permitted Investments and all other
customary and ancillary income and fees shall be retained by the Servicer to the
extent not required to be deposited in the Servicer Custodial Account pursuant
to Section 3.08(b). The Servicer shall be required to pay all expenses incurred
by it in connection with its servicing activities hereunder and shall not be
entitled to reimbursement therefor except as specifically provided in this
Agreement.

          Notwithstanding the foregoing, with respect to the payment of the
Servicing Fee on any Distribution Date, the aggregate Servicing Fee for the
Servicer for such Distribution Date shall be reduced (but not below zero) by an
amount equal to the lesser of (a) the Prepayment Interest Shortfall for such
Distribution Date relating to the Mortgage Loans and (b) one-twelfth of 0.25% of
the aggregate Stated Principal Balance of such Mortgage Loans for such
Distribution Date (any such reduction, "Compensating Interest").

          Section 3.18 Annual Statement as to Compliance.

          The Servicer shall deliver to the Trustee and each Rating Agency on or
before 90 days after the end of the Servicer's fiscal year, commencing with its
           fiscal year, an Officer's Certificate stating, as to the signer
thereof, that (a) a review of the activities of the

                                      -55-

<PAGE>

Servicer during the preceding calendar year and of the performance of the
Servicer under this Agreement has been made under such officer's supervision,
and (b) to the best of such officer's knowledge, based on such review, the
Servicer has fulfilled all its obligations under this 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.

          Section 3.19 Annual Independent Public Accountants' Servicing
Statement; Financial Statements.

          The Servicer shall, at its own expense, on or before 90 days after the
end of the Servicer's fiscal year, commencing with its 2002 fiscal year, cause a
firm of independent public accountants (who may also render other services to
the Servicer or any affiliate thereof) which is a member of the American
Institute of Certified Public Accountants to furnish a statement to the Trustee
to the effect that such firm has with respect to the Servicer's overall
servicing operations, examined such operations in accordance with the
requirements of the Uniform Single Attestation Program for Mortgage Bankers,
stating such firm's conclusions relating thereto.

          Section 3.20 Advances.

          The Servicer shall determine on or before each Servicer Advance Date
whether it is required to make a Periodic Advance pursuant to the definition
thereof. If the Servicer determines it is required to make a Periodic Advance,
it shall, on or before the Servicer Advance Date, either (a) deposit into the
Servicer Custodial Account an amount equal to the Advance and/or (b) make an
appropriate entry in its records relating to the Servicer Custodial Account that
any portion of the Amount Held for Future Distribution in the Servicer Custodial
Account has been used by the Servicer in discharge of its obligation to make any
such Periodic Advance. Any funds so applied shall be replaced by the Servicer by
deposit in the Servicer Custodial Account no later than the close of business on
the Business Day preceding the next Servicer Advance Date. The Servicer shall be
entitled to be reimbursed from the Servicer Custodial Account for all Advances
of its own funds made pursuant to this Section 3.20 as provided in Section
3.11(a). The obligation to make Periodic Advances with respect to any Mortgage
Loan shall continue until the ultimate disposition of the REO Property or
Mortgaged Property relating to such Mortgage Loan. The Servicer shall inform the
Trustee of the amount of the Periodic Advance to be made by the Servicer on each
Servicer Advance Date no later than the related Remittance Date.

          The Servicer shall deliver to the Trustee on the related Servicer
Advance Date an Officer's Certificate of a Servicing Officer indicating the
amount of any proposed Periodic Advance determined by the Servicer to be a
Nonrecoverable Advance. Notwithstanding anything to the contrary, the Servicer
shall not be required to make any Periodic Advance or Servicing Advance that
would be a Nonrecoverable Advance.

          Section 3.21 Modifications, Waivers, Amendments and Consents.

          (a) Subject to this Section 3.21, the Servicer may agree to any
modification, waiver, forbearance, or amendment of any term of any Mortgage Loan
without the consent of the

                                      -56-

<PAGE>

Trustee or any Certificateholder. All modifications, waivers, forbearances or
amendments of any Mortgage Loan shall be in writing and shall be consistent with
Customary Servicing Procedures.

          (b) The Servicer shall not agree to enter into, and shall not enter
into, any modification, waiver (other than a waiver referred to in Section 3.13,
which waiver, if any, shall be governed by Section 3.13), forbearance or
amendment of any term of any Mortgage Loan if such modification, waiver,
forbearance, or amendment would:

          (i)     affect the amount or timing of any related payment of
     principal, interest or other amount payable thereunder;

          (ii)    in the Servicer's judgment, materially impair the security for
     such Mortgage Loan or reduce the likelihood of timely payment of amounts
     due thereon; or

          (iii)   otherwise constitute a "significant modification" within the
     meaning of Treasury Regulations Section 1.860G-2(b);

unless, in either case, (A) such Mortgage Loan is 90 days or more past due or
(B) the Servicer delivers to the Trustee an Opinion of Counsel to the effect
that such modification, waiver, forbearance or amendment would not affect the
REMIC status of either the Upper-Tier REMIC or the Lower-Tier REMIC and, in
either case, such modification, waiver, forbearance or amendment is reasonably
likely to produce a greater recovery with respect to such Mortgage Loan than
would liquidation. Subject to Customary Servicing Procedures, the Servicer may
permit a forbearance for a Mortgage Loan which in the Servicer's judgment is
subject to imminent default.

          (c) Any payment of interest, which is deferred pursuant to any
modification, waiver, forbearance or amendment permitted hereunder, shall not,
for purposes hereof, including, without limitation, calculating monthly
distributions to Certificateholders, be added to the unpaid principal balance of
the related Mortgage Loan, notwithstanding that the terms of such Mortgage Loan
or such modification, waiver or amendment so permit.

          (d) The Servicer may, as a condition to granting any request by a
Mortgagor for consent, modification, waiver, forbearance or amendment, the
granting of which is within the Servicer's discretion pursuant to the Mortgage
Loan and is permitted by the terms of this Agreement, require that such
Mortgagor pay to the Servicer, as additional servicing compensation, a
reasonable or customary fee for the additional services performed in connection
with such request, together with any related costs and expenses incurred by the
Servicer, which amount shall be retained by the Servicer as additional servicing
compensation.

          (e) The Servicer shall notify the Trustee, in writing, of any
modification, waiver, forbearance or amendment of any term of any Mortgage Loan
and the date thereof, and shall deliver to the Trustee (or, at the direction of
the Trustee, the Custodian) for deposit in the related Mortgage File, an
original counterpart of the agreement relating to such modification, waiver,
forbearance or amendment, promptly (and in any event within ten Business Days)
following the execution thereof; provided, however, that if any such
modification, waiver, forbearance or amendment is required by applicable law to
be recorded, the Servicer (i) shall deliver to the

                                      -57-

<PAGE>

Trustee a copy thereof and (ii) shall deliver to the Trustee such document, with
evidence of notification upon receipt thereof from the public recording office.

          Section 3.22 Reports to the Securities and Exchange Commission.

          The Trustee shall, on behalf of the Trust, cause to be filed with the
Securities and Exchange Commission any periodic reports required to be filed
under the provisions of the Securities Exchange Act of 1934, as amended, and the
rules and regulations of the Securities and Exchange Commission thereunder, for
so long as any Certificates registered under the 1933 Act are outstanding (other
than the Current Report on Form 8-K to be filed by the Depositor in connection
with computational materials and the initial Current Report on Form 8-K to be
filed by the Depositor in connection with the issuance of the Certificates).
Upon the request of the Trustee, the Servicer and the Depositor shall cooperate
with the Trustee in the preparation of any such report and shall provide to the
Trustee in a timely manner all such information or documentation as the Trustee
may reasonably request in connection with the performance of its duties and
obligations under this Section.

                             SERVICER'S CERTIFICATE

          Section 4.01 Servicer's Certificate.

          Each month, not later than 12:00 noon Eastern time on the Business Day
following each Determination Date, the Servicer shall deliver to the Trustee, a
Servicer's Certificate (in substance and format mutually acceptable to the
Servicer and the Trustee) certified by a Servicing Officer setting forth the
information necessary in order for the Trustee to perform its obligations under
this Agreement. The Trustee may conclusively rely upon the information contained
in a Servicer's Certificate for all purposes hereunder and shall have no duty to
verify or re-compute any of the information contained therein.

          Each such statement shall be provided by the Trustee to any Holder of
a Certificate upon request and shall also, to the extent available, include
information regarding delinquencies on Mortgage Loans providing such statement,
indicating the number and aggregate principal amount of Mortgage Loans which are
either one, two, three or more than three months delinquent and the book value
of any REO Property.

          Section 5.01 Distributions. On each Distribution Date, based solely on
the information in the Servicer's Certificate, the Trustee shall distribute out
of the Upper-Tier Certificate Account or the Certificate Account, as applicable,

on the related Record Date (other than as provided in Section 10.01 respecting
the final distribution) (a) by check mailed to such Certificateholder

entitled to receive a distribution on such Distribution Date at the address
appearing in the Certificate Register, or (b) upon written request by the Holder
of a Regular Certificate (in the event such Certificateholder owns of record
100% of a Class of Certificates or holds Certificates of any Class having
denominations aggregating $1,000,000 or more), by wire transfer or by such other
means of payment as such Certificateholder and the Trustee shall agree upon,
such Certificateholder's Percentage Interest in the amount to which the related
Class of Certificates is entitled in accordance with the priorities set forth
below in Section 5.02.

          None of the Holders of any Class of Certificates, the Depositor, the
Servicer or the Trustee shall in any way be responsible or liable to Holders of
any Class of Certificates in respect of amounts properly previously distributed
on any such Class.

          Amounts distributed with respect to any Class of Certificates shall be
applied first to the distribution of interest thereon and then to principal
thereon.

          Section 5.02 Priorities of Distributions.

          (a) On each Distribution Date, based solely on the information
contained in the Servicer's Certificate, the Trustee shall withdraw from the
Certificate Account (to the extent funds are available therein) (1) the amounts
payable to the Trustee pursuant to Sections 3.11(b)(i) and 3.11(b)(ii) and shall
pay such funds to itself, and (2) the Pool Distribution Amount, in an amount as
specified in written notice received by the Trustee from the Servicer no later
than the related Determination Date, and shall apply such funds, first, to
distributions in respect of the Uncertificated Lower-Tier Interests as specified
in this Section 5.02(a) for deposit in the Upper-Tier Certificate Account and to
the Class A-LR Certificate, and then from the Upper-Tier Certificate Account to
distributions on the Certificates in the following order of priority and to the
extent of such funds:

          (i)     to each Class of Senior Certificates (other than the Class
     A-PO and Class A-LR Certificates), an amount allocable to interest equal to
     the Interest Distribution Amount for such Class and any shortfall being
     allocated among such Classes in proportion to the amount of the Interest
     Distribution Amount that would have been distributed in the absence of such
     shortfall;

          (ii)    concurrently to the Class A Certificates (other than the Class
     A-PO and Class A-LR Certificates) and the Class A-PO Certificates, pro
     rata, based on their respective Senior Principal Distribution Amount and PO
     Principal Amount, (A) to the Class A Certificates (other than the Class
     A-PO Certificates), in an aggregate amount up to the Senior Principal

     in accordance with Section 5.02(b) and (B) to the Class A-PO Certificates
     in an aggregate amount up to the PO Principal Amount;

          interest equal to the Interest Distribution Amount for such Class for
          such Distribution Date;

                  (B)     to the Class B-1 Certificates, an amount allocable to

          clause (iii) above until the Class Certificate Balance thereof has
          been reduced to zero;

                  (C)     to the Class B-2 Certificates, an amount allocable to
          interest equal to the Interest Distribution Amount for such Class for

          been reduced to zero;

                  (E)     to the Class B-3 Certificates, an amount allocable to

                  (K)     to the Class B-6 Certificates, an amount allocable to
          interest equal to the Interest Distribution Amount for such Class for
          such Distribution Date; and

                                      -60-

<PAGE>

                  (L)     to the Class B-6 Certificates, an amount allocable to
          principal equal to its Pro Rata Share for such Distribution Date less
          any amount used to pay the Class A-PO Deferred Amount pursuant to
          clause (iii) above until the Class Certificate Balance thereof has
          been reduced to zero; and

          (v)     to the Holder of the Class A-R Certificate, any amounts
     remaining in the Upper-Tier Certificate Account, and to the Holder of the
     Class A-LR Certificate, any remaining Pool Distribution Amount.

          On any Distribution Date, amounts distributed in respect of Class A-PO
Deferred Amounts will not reduce the Class Certificate Balance of the Class A-PO
Certificates.

          All distributions in respect of the Interest Distribution Amount for a
Class will be applied first with respect to the amount payable pursuant to
clause (i) of the definition of "Interest Distribution Amount," and second with
respect to the amount payable pursuant to clause (ii) of such definition.

          On each Distribution Date, each Uncertificated Lower-Tier Interest
shall receive distributions in respect of principal in an amount equal to the
amount of principal distributed to their respective Corresponding Upper-Tier
Class or Classes as provided herein. On each Distribution Date, each
Uncertificated Lower-Tier Interest shall receive distributions in respect of
interest in an amount equal to the Interest Distribution Amounts in respect of
its Corresponding Upper-Tier Class or Classes, in each case to the extent
actually distributed thereon. Such amounts distributed to the Uncertificated
Lower-Tier Interests in respect of principal and interest with respect to any
Distribution Date are referred to herein collectively as the "Lower-Tier
Distribution Amount."

          As of any date, the principal balance of each Uncertificated
Lower-Tier Interest equals the aggregate of the Class Certificate Balances of
the respective Corresponding Upper-Tier Class or Classes. The initial principal
balance of each Uncertificated Lower-Tier Interest equals the aggregate of the
Initial Class Certificate Balances (or notional amount) of the respective
Corresponding Upper-Tier Class or Classes.

          The pass-through rate with respect to the Class A-L1 Interest, Class
A-LUR Interest, Class B-L1 Interest, Class B-L2 Interest, Class B-L3 Interest,
Class B-L4 Interest, Class B-L5 Interest and Class B-L6 Interest shall be      %
per annum. The pass-through rate with respect to the Class A-L3 Interest shall
be      % per annum. The pass-through rate with respect to the Class A-L4
Interest shall be      % per annum. The Class A-LPO Interest is a principal-only
interest and is not entitled to distributions of interest. Any Non-Supported
Interest Shortfalls will be allocated to each Uncertificated Lower-Tier Interest
in the same relative proportions as interest is allocated to such Uncertificated
Lower-Tier Interest.

          (b) (i) On each Distribution Date prior to the Senior Credit Support
Depletion Date, the amount distributable to the Class A Certificates (other than
the Class A-PO Certificates) pursuant to Section 5.02(a)(ii) for such
Distribution Date, will be distributed in the following order of priority:

                  [To Be Provided]

                                      -61-

<PAGE>

          On each Distribution Date on or after the Senior Credit Support
Depletion Date, notwithstanding the allocation and priority set forth above, the
portion of the Pool Distribution Amount available to be distributed as principal
of the Class A Certificates (other than the Class A-PO Certificates) shall be
distributed concurrently, as principal, on such Classes, pro rata, on the basis
of their respective Class Certificate Balances, until the Class Certificate
Balances thereof are reduced to zero.

          (c) On each Distribution Date, Accrued Certificate Interest for each
Class of Certificates for such Distribution Date shall be reduced by such
Class's pro rata share, based on such Class's Interest Distribution Amount for
such Distribution Date, without taking into account the allocation made by this
Section 5.02(c), of (A) Non-Supported Interest Shortfalls, (B) any Excess Losses
allocable to interest, (C) on and after the Senior Credit Support Depletion
Date, any other Realized Loss allocable to interest and (D) each Relief Act
Reduction incurred during the calendar month preceding the month of such
Distribution Date.

          (d) Notwithstanding the priority and allocation contained in Section
5.02(a)(iv), if with respect to any Class of Subordinate Certificates on any
Distribution Date, (i) the aggregate of the Class Certificate Balances
immediately prior to such Distribution Date of all Classes of Subordinate
Certificates which have a higher numerical Class designation than such Class,
divided by (ii) the aggregate Class Certificate Balance of all the Certificates
(other than the Class A-PO Certificates) immediately prior to such Distribution
Date (the "Fractional Interest") is less than the Original Fractional Interest
for such Class, no distribution of principal will be made to any Classes junior
to such Class (the "Restricted Classes") and the Class Certificate Balances of
the Restricted Classes will not be used in determining the Pro Rata Share for
the Subordinate Certificates that are not Restricted Classes. Any funds
remaining will be distributed in the order provided in Section 5.02(a)(iv).

          Section 5.03 Allocation of Losses.

          (a) On or prior to each Determination Date, the Servicer shall inform
the Trustee in writing with respect to each Mortgage Loan: (1) whether any
Realized Loss is a Deficient Valuation or a Debt Service Reduction, (2) of the
amount of such loss or Deficient Valuation, or of the terms of such Debt Service
Reduction and (3) of the total amount of Realized Losses. Based on such
information, the Trustee shall determine the total amount of Realized Losses
with respect to the related Distribution Date.

          The principal portion of Realized Losses with respect to any
Distribution Date shall be allocated as follows:

          (i)     the applicable PO Percentage of the principal portion of any
     Realized Loss with respect to a Discount Mortgage Loan shall be allocated
     to the Class A-PO Certificates until the Class Certificate Balance thereof
     is reduced to zero; and

          (ii)    the applicable Non-PO Percentage of the principal portion of
     any Realized Loss shall be allocated first to the Subordinate Certificates
     in reverse order of their respective numerical Class designations
     (beginning with the Class of Subordinate Certificates then outstanding with
     the highest numerical Class designation) until the

                                      -62-

<PAGE>

     respective Class Certificate Balance of each such Class is reduced to zero,
     and second to the Senior Certificates (other than the Class A-PO
     Certificates), pro rata, on the basis of their respective Class Certificate
     Balances immediately prior to the related Distribution Date, until the
     Class Certificate Balances thereof have been reduced to zero; and

          (b) The Class Certificate Balance of the Class A-PO Certificates shall
be reduced on each Distribution Date by the amount, if any, by which the Class
Certificate Balance of the Class A-PO Certificates (after giving effect to the
amount to be distributed as a distribution of principal and the allocation of
Realized Losses on such Distribution Date) exceeds the Adjusted Pool Amount (PO
Portion) for such Distribution Date.

          The Class Certificate Balance of the Class of Subordinate Certificates
then outstanding with the highest numerical Class designation shall be reduced
on each Distribution Date by the amount, if any, by which the aggregate of the
Class Certificate Balances of all outstanding Classes of Certificates (after
giving effect to the amount to be distributed as a distribution of principal and
the allocation of Realized Losses and Class A-PO Deferred Amounts on such
Distribution Date) exceeds the Adjusted Pool Amount for such Distribution Date.

          After the Senior Credit Support Depletion Date, the Class Certificate
Balances of the Senior Certificates in the aggregate (other than the Class
Certificate Balance of the Class A-PO Certificates) shall be reduced on each
Distribution Date by the amount, if any, by which the aggregate of the Class
Certificate Balances of all outstanding Classes of Senior Certificates (other
than Class A-PO Certificates) (after giving effect to the amount to be
distributed as a distribution of principal and the allocation of Realized Losses
on such Distribution Date) exceeds the difference between (i) the Adjusted Pool
Amount for such Distribution Date and (ii) the Adjusted Pool Amount (PO Portion)
for such Distribution Date.

          Any such reduction shall be allocated among the Senior Certificates
(other than the Class A-PO Certificates) based on the Class Certificate Balances
immediately prior to such Distribution Date.

          (c) Any Realized Loss allocated to a Class of Certificates or any
reduction in the Class Certificate Balance of a Class of Certificates pursuant
to Section 5.03(b) above shall be allocated among the Certificates of such Class
in proportion to their respective Percentage Interests.

          (d) Any allocation of Realized Losses to a Class of Certificates or
any reduction in the Class Certificate Balance of a Class pursuant to Section
5.03(b) above shall be accomplished by reducing the Class Certificate Balance
thereof prior to the distributions made on the related Distribution Date in
accordance with the definition of "Class Certificate Balance."

          (e) With respect to any Distribution Date, Realized Losses allocated
pursuant to this Section 5.03 will be allocated to each Uncertificated
Lower-Tier Interest in an amount equal to the amount allocated to its respective
Corresponding Upper-Tier Class or Classes as provided above.

(ix) of Section 5.04(a), the amounts shall be expressed as a dollar amount per
Certificate with a $1,000 denomination.

          On each Distribution Date, the Trustee shall prepare and furnish to
each Financial Market Service, in electronic or such other format and media
mutually agreed upon by the Trustee, the Financial Market Service and the
Depositor, the information contained in the statement described in Section
5.04(a) for such Distribution Date.

          The Trustee may make available each month, to any interested party,
the monthly statement to Certificateholders via the Trustee's website.

          Within a reasonable period of time after the end of each calendar
year, the Trustee shall furnish to each Person who at any time during the
calendar year was the Holder of a Certificate, if requested in writing by such
Person, a statement containing the information set forth in clauses (i), (ii)
and (vii) of Section 5.04(a), in each case aggregated for such calendar year or
applicable portion thereof during which such Person was a Certificateholder.
Such obligation of the Trustee shall be deemed to have been satisfied to the
extent that substantially comparable information shall be provided by the
Trustee pursuant to any requirements of the Code as from time to time in force.

          The Trustee shall deliver to the Holders of Certificates any reports
or information the Trustee is required by this Agreement or the Code, Treasury
Regulations or REMIC Provisions to deliver to the Holders of Certificates, and
the Trustee shall prepare and provide to the Certificateholders (by mail,
telephone, or publication as may be permitted by applicable Treasury
Regulations) such other reasonable information as the Trustee deems necessary or
appropriate or is required by the Code, Treasury Regulations, and the REMIC
Provisions including, but not limited to, (i) information to be reported to the
Holders of the Residual Certificates for quarterly notices on Schedule Q (Form
1066) (which information shall be forwarded to the Holders of the Residual
Certificates by the Trustee), (ii) information to be provided to the Holders of
Certificates with respect to amounts which should be included as interest and
original issue discount in such Holders' gross income and (iii) information to
be provided to all Holders of Certificates setting forth the percentage of each
REMIC's assets, determined in accordance with Treasury Regulations using a

                                      -65-

<PAGE>

assets under Section 856 of the Code, and assets described in Section
7701(a)(19)(C) of the Code; provided, however, that in setting forth the
percentage of such assets of each REMIC, nothing contained in this Agreement,
including without limitation Section 7.03 hereof, shall be interpreted to
require the Trustee periodically to appraise the fair market values of the
assets of the Trust Estate or to indemnify the Trust Estate or any
Certificateholders from any adverse federal, state or local tax consequences
associated with a change subsequently required to be made in the Depositor's
initial good faith determinations of such fair market values (if subsequent
determinations are required pursuant to the REMIC Provisions) made from time to
time.

          Section 5.05 Tax Returns and Reports to Certificateholders.

          (a) For federal income tax purposes, each REMIC shall have a calendar
year taxable year and shall maintain its books on the accrual method of
accounting.

          (b) The Trustee shall prepare or cause to be prepared, shall execute
and shall file or cause to be filed with the Internal Revenue Service and
applicable state or local tax authorities income tax information returns for
each taxable year with respect to each REMIC containing such information at the
times and in the manner as may be required by the Code, the Treasury Regulations
or state or local tax laws, regulations, or rules, and shall furnish or cause to
be furnished to each REMIC and the Certificateholders the schedules, statements
or information at such times and in such manner as may be required thereby.
Within 30 days of the Closing Date, the Trustee shall furnish or cause to be
furnished to the Internal Revenue Service, on Form 8811 or as otherwise required
by the Code or the Treasury Regulations, the name, title, address and telephone
number of the person that Holders of the Certificates may contact for tax
information relating thereto, together with such additional information at the
time or times and in the manner required by the Code or the Treasury
Regulations. Such federal, state, or local income tax or information returns
shall be signed by the Trustee, or such other Person as may be required to sign
such returns by the Code, the Treasury Regulations or state or local tax laws,
regulations, or rules.

          (c) In the first federal income tax return of each REMIC for its short
taxable year ending December 31, 20 , REMIC status shall be elected for such
taxable year and all succeeding taxable years.

          (d) The Trustee will maintain or cause to be maintained such records
relating to each REMIC, including but not limited to records relating to the
income, expenses, assets and liabilities of the Trust Estate, and the initial
fair market value and adjusted basis of the Trust Estate property and assets
determined at such intervals as may be required by the Code or the Treasury
Regulations, as may be necessary to prepare the foregoing returns, schedules,
statements or information.

          Section 5.06 Tax Matters Person. The Tax Matters Person shall have the
same duties with respect to each REMIC as those of a "tax matters partner" under
Subchapter C of Chapter 63 of Subtitle F of the Code. The Holder of the Class
A-R Certificate is hereby designated as the Tax Matters Person for the
Upper-Tier REMIC. The Holder of the Class A-LR Certificate is hereby designated
as the Tax Matters Person for the Lower-Tier REMIC. By their

                                      -66-

<PAGE>

acceptance of the Class A-R or Class A-LR Certificate, as applicable, each such
Holder irrevocably appoints the Trustee as its agent to perform all of the
duties of the Tax Matters Person for the Upper-Tier REMIC and the Lower-Tier
REMIC.

          Section 5.07 Rights of the Tax Matters Person in Respect of the
Trustee. The Trustee shall afford the Tax Matters Person, upon reasonable notice
during normal business hours, access to all records maintained by the Trustee in
respect of its duties hereunder and access to officers of the Trustee
responsible for performing such duties. Upon request, the Trustee shall furnish
the Tax Matters Person with its most recent report of condition published
pursuant to law or to the requirements of its supervisory or examining authority
publicly available. The Trustee shall make available to the Tax Matters Person
such books, documents or records relating to the Trustee's services hereunder as
the Tax Matters Person shall reasonably request. The Tax Matters Person shall
not have any responsibility or liability for any action or failure to act by the
Trustee and is not obligated to supervise the performance of the Trustee under
this Agreement or otherwise.

          Section 5.08 REMIC Related Covenants. For as long as the Trust shall
exist, the Trustee, the Depositor and the Servicer shall act in accordance
herewith to assure continuing treatment of the Upper-Tier REMIC and the
Lower-Tier REMIC as REMICs and avoid the imposition of tax on either REMIC. In
particular:

          (a) The Trustee shall not create, or permit the creation of, any
"interests" in either REMIC within the meaning of Code Section 860D(a)(2) other
than the interests represented by the Regular Certificates, the Residual
Certificates and the Uncertificated Lower-Tier Interests.

          (b) Except as otherwise provided in the Code, (i) the Depositor and
the Servicer shall not contribute to the Trust Estate and the Trustee shall not
accept property unless substantially all of the property held in each REMIC
constitutes either "qualified mortgages" or "permitted investments" as defined
in Code Sections 860G(a)(3) and (5), respectively, and (ii) no property shall be
contributed to each REMIC after the start-up day unless such contribution would
not subject the Trust Estate to the 100% tax on contributions to a REMIC after
the start-up day of the REMIC imposed by Code Section 860G(d).

          (c) The Trustee shall not accept on behalf of either REMIC any fee or
other compensation for services and neither the Trustee nor the Servicer shall
knowingly accept, on behalf of the Trust Estate any income from assets other
than those permitted to be held by a REMIC.

          (d) The Trustee shall not sell or permit the sale of all or any
portion of the Mortgage Loans (other than in accordance with Sections 2.02, 2.04
or 3.14(b)), unless such sale is pursuant to a "qualified liquidation" of the
applicable REMIC as defined in Code Section 860F(a)(4)(A) and in accordance with
Article X.

          (e) The Trustee shall maintain books with respect to the Trust and
each REMIC on a calendar year taxable year and on an accrual basis.

          Neither the Servicer nor the Trustee shall engage in a "prohibited
transaction" (as defined in Code Section 860F(a)(2)), except that, with the
prior written consent of the Servicer

                                      -67-

<PAGE>

and the Depositor, the Trustee may engage in the activities otherwise prohibited
by the foregoing paragraphs (b), (c) and (d); provided that the Servicer shall
have delivered to the Trustee an Opinion of Counsel to the effect that such
transaction will not result in the imposition of a tax on either REMIC and will
not disqualify the Trust Estate from treatment as two REMICs; and, provided
further, that the Servicer shall have demonstrated to the satisfaction of the
Trustee that such action will not adversely affect the rights of the Holders of
the Certificates and the Trustee and that such action will not adversely impact
the rating of the Certificates.

                                   ARTICLE VI

                                THE CERTIFICATES

          Section 6.01 The Certificates. The Classes of Senior Certificates and

B-6 and C (reverse of all Certificates) and shall, on original issue, be
executed by the Trustee and shall be countersigned and delivered by the Trustee
to or upon the order of the Depositor upon receipt by the Trustee of the
documents specified in Section 2.01. The Senior Certificates (other than the
Class A-PO and Class A-R Certificates) shall be available to investors in
interests representing minimum dollar Certificate Balances (or notional amounts)
of $ and integral multiples of $ in excess thereof. The Subordinate Certificates
and the Class A-PO Certificates shall be available to investors in interests
representing minimum dollar Certificate Balances of $ and integral dollar
multiples of $1 in excess thereof (except one Certificate of such Class may be
issued with a different Certificate Balance. The Class A-R and Class A-LR
Certificates shall be in a minimum denomination of $ . The Senior Certificates
(other than the Class A-R and Class A-LR Certificates) and the Class B-1, Class

Depository's instructions on behalf of the Depository to, and deposited with,
the Certificate Custodian, and all other Classes of Certificates shall initially
be issued in definitive, fully-registered form.

          The Certificates shall be executed by manual or facsimile signature on
behalf of the Trustee by an authorized officer or signatory. Certificates
bearing the manual or facsimile signatures of individuals who were, at the time
when such signatures were affixed, authorized to sign on behalf of the Trustee
shall bind the Trustee, notwithstanding that such individuals or any of them
have ceased to be so authorized prior to the execution and delivery of such
Certificates or did not hold such offices or positions at the date of such
Certificate. No Certificate shall be entitled to any benefit under this
Agreement, or be valid for any purpose, unless such Certificate shall have been
manually countersigned by the Trustee substantially in the form provided for
herein, and such countersignature upon any Certificate shall be conclusive
evidence, and the only evidence, that such Certificate has been duly
authenticated and delivered hereunder. All Certificates shall be dated the date
of their countersignature.

          Section 6.02 Registration of Transfer and Exchange of Certificates.

          (a) The Trustee shall cause to be kept at an office or agency in the
city in which the Corporate Trust Office of the Trustee is located a Certificate
Register in which, subject to

                                      -68-

<PAGE>

such reasonable regulations as it may prescribe, the Trustee shall provide for
the registration of Certificates and of transfers and exchanges of Certificates
as herein provided. The Trustee shall initially serve as Certificate Registrar
for the purpose of registering Certificates and transfers and exchanges of
Certificates as herein provided.

          (b) At the option of the Certificateholders, Certificates may be
exchanged for other Certificates of authorized denominations of a like Class,
tenor and aggregate Percentage Interest, upon surrender of the Certificates to
be exchanged at any such office or agency. Whenever any Certificates are so
surrendered for exchange, the Trustee shall execute and the Trustee shall
authenticate, countersign and deliver the Certificates which the
Certificateholder making the exchange is entitled to receive. Every Certificate
presented or surrendered for transfer or exchange shall (if so required by the
Trustee or the Certificate Registrar) be duly endorsed by, or be accompanied by
a written instrument of transfer in form satisfactory to the Trustee and the
Certificate Registrar duly executed by, the Holder thereof or its attorney duly
authorized in writing.

          (c) (i) Except as provided in paragraph (c)(iii) below, the Book-Entry
     Certificates shall at all times remain registered in the name of the
     Depository or its nominee and at all times: (A) registration of the
     Certificates may not be transferred by the Trustee except to another
     Depository; (B) the Depository shall maintain book-entry records with
     respect to the Certificate Owners and with respect to ownership and
     transfers of such Book-Entry Certificates; (C) ownership and transfers of
     registration of the Book-Entry Certificates on the books of the Depository
     shall be governed by applicable rules established by the Depository; (D)
     the Depository may collect its usual and customary fees, charges and
     expenses from its Depository Participants; (E) the Trustee shall deal with
     the Depository as the representative of the Certificate Owners of the
     Book-Entry Certificates for purposes of exercising the rights of Holders
     under this Agreement, and requests and directions for and votes of the
     Depository shall not be deemed to be inconsistent if they are made with
     respect to different Certificate Owners; and (F) the Trustee may rely and
     shall be fully protected in relying upon information furnished by the
     Depository with respect to its Depository Participants and furnished by the
     Depository Participants with respect to indirect participating firms and
     persons shown on the books of such indirect participating firms as direct
     or indirect Certificate Owners.

          (ii)    All transfers by Certificate Owners of Book-Entry Certificates
     shall be made in accordance with the procedures established by the
     Depository Participant or brokerage firm representing such Certificate
     Owner. Each Depository Participant shall only transfer Book-Entry
     Certificates of Certificate Owners it represents or of brokerage firms for
     which it acts as agent in accordance with the Depository's normal
     procedures.

          (iii)   If (A) (1) the Depository or the Depositor advises the Trustee
     in writing that the Depository is no longer willing or able to properly
     discharge its responsibilities as Depository, and (2) the Trustee or the
     Depositor is unable to locate a qualified successor, (B) the Depositor at
     its option advises the Trustee in writing that it elects to terminate the
     book-entry system through the Depository or (C) after the occurrence of an
     Event of Default, Certificate Owners representing at least 51% of the
     aggregate Class Certificate Balances of the Book-Entry Certificates
     together advise the Trustee and the

                                      -69-

<PAGE>

     Depository through the Depository Participants in writing that the
     continuation of a book-entry system through the Depository is no longer in
     the best interests of the Certificate Owners, the Trustee shall notify all
     Certificate Owners, through the Depository, of the occurrence of any such
     event and of the availability of definitive, fully-registered Certificates
     (the "Definitive Certificates") to Certificate Owners requesting the same.
     Upon surrender to the Trustee of the related Class of Certificates by the
     Depository (or by the Certificate Custodian, if it holds such Class on
     behalf of the Depository), accompanied by the instructions from the
     Depository for registration, the Trustee shall issue the Definitive
     Certificates. None of the Servicer, the Depositor or the Trustee shall be
     liable for any delay in delivery of such instruction and may conclusively
     rely on, and shall be protected in relying on, such instructions. The
     Depositor shall provide the Trustee with an adequate inventory of
     certificates to facilitate the issuance and transfer of Definitive
     Certificates. Upon the issuance of Definitive Certificates, the Trustee
     shall recognize the Holders of the Definitive Certificates as
     Certificateholders hereunder.

          (d) No transfer of a Private Certificate shall be made unless such
transfer is exempt from the registration requirements of the 1933 Act and any
applicable state securities laws or is made in accordance with the 1933 Act and
such laws. In the event of any such transfer, (i) unless such transfer is made
in reliance on Rule 144A under the 1933 Act, the Trustee or the Depositor may
require a written Opinion of Counsel (which may be in-house counsel) acceptable
to and in form and substance reasonably satisfactory to the Trustee and the
Depositor that such transfer may be made pursuant to an exemption, describing
the applicable exemption and the basis therefor, from the 1933 Act and such laws
or is being made pursuant to the 1933 Act and such laws, which Opinion of
Counsel shall not be an expense of the Trustee or the Depositor and (ii) the
Trustee shall require a certificate from the Certificateholder desiring to
effect such transfer substantially in the form attached hereto as Exhibit G-1
and a certificate from such Certificateholder's prospective transferee
substantially in the form attached hereto either as Exhibit G-2A or as Exhibit
G-2B, which certificates shall not be an expense of the Trustee or the
Depositor; provided that the foregoing requirements under clauses (i) and (ii)
shall not apply to a transfer of a Private Certificate between or among the
Depositor, the Seller, their affiliates or both. The Depositor shall provide to
any Holder of a Private Certificate and any prospective transferees designated
by any such Holder, information regarding the related Certificates and the
Mortgage Loans and such other information as shall be necessary to satisfy the
condition to eligibility set forth in Rule 144A(d)(4) for transfer of any such
certificate without registration thereof under the 1933 Act pursuant to the
registration exemption provided by Rule 144A. The Holder of a Private
Certificate desiring to effect such transfer shall, and does hereby agree to,
indemnify the Trustee and the Depositor against any liability that may result if
the transfer is not so exempt or is not made in accordance with such federal and
state laws.

          (e) No transfer of an ERISA Restricted Certificate shall be made
unless the transferee delivers to the Trustee either (i) a representation letter
in the form of Exhibit H from the transferee of such Certificate, which
representation letter shall not be an expense of the Depositor, the Trustee or
the Servicer, or (ii) in the case of any ERISA Restricted Certificate presented
for registration in the name of an employee benefit plan or arrangement,
including an individual retirement account, subject to ERISA, the Code, or any
federal, state or local law ("Similar Law") which is similar to ERISA or the
Code (collectively, a "Plan"), or a trustee or custodian of any of the
foregoing, an Opinion of Counsel in form and substance satisfactory to

                                      -70-

<PAGE>

the Trustee and the Servicer to the effect that the purchase or holding of such
ERISA Restricted Certificate by or on behalf of such Plan will not result in the
assets of the Trust Estate being deemed to be "plan assets" and subject to the
prohibited transaction provisions of ERISA, the Code or Similar Law and will not
subject the Trustee, the Depositor or the Servicer to any obligation in addition
to those undertaken in this Agreement, which Opinion of Counsel shall not be an
expense of the Trustee or the Servicer. Any transferee of an ERISA Restricted
Certificate that does not comply with either clause (i) or (ii) of the preceding
sentence will be deemed to have made one of the representations set forth in
Exhibit H. Notwithstanding anything else to the contrary herein, any purported
transfer of an ERISA Restricted Certificate to or on behalf of a Plan without
the delivery to the Trustee and the Servicer of an Opinion of Counsel
satisfactory to the Trustee and the Servicer as described above shall be void
and of no effect.

          Neither the Trustee nor the Certificate Registrar shall have any
liability for transfers of Book-Entry Certificates made through the book-entry
facilities of the Depository or between or among any Depository Participants or
Certificate Owners, made in violation of applicable restrictions. The Trustee
may rely and shall be fully protected in relying upon information furnished by
the Depository with respect to its Depository Participants and furnished by the
Depository Participants with respect to indirect participating firms and Persons
shown on the books of such indirect participating firms as direct or indirect
Certificate Owners.

          To the extent permitted under applicable law (including, but not
limited to, ERISA), the Trustee shall be under no liability to any Person for
any registration of transfer of any ERISA Restricted Certificate that is in fact
not permitted by this Section 6.02 or for making any payments due on such
Certificate to the Holder thereof or taking any other action with respect to
such Holder under the provisions of this Agreement so long as the transfer was
registered by the Trustee in accordance with the foregoing requirements.

          (f) Each Person who has or who acquires any Ownership Interest in a
Residual Certificate shall be deemed by the acceptance or acquisition of such
Ownership Interest to have agreed to be bound by the following provisions, and
the rights of each Person acquiring any Ownership Interest in a Residual
Certificate are expressly subject to the following provisions:

          (i)     Each Person holding or acquiring any Ownership Interest in a
     Residual Certificate shall be a Permitted Transferee and shall promptly
     notify the Trustee of any change or impending change in its status as a
     Permitted Transferee.

          (ii)    No Person shall acquire an Ownership Interest in a Residual
     Certificate unless such Ownership Interest is a pro rata undivided
     interest.

          (iii)   In connection with any proposed transfer of any Ownership
     Interest in a Residual Certificate, the Trustee shall require delivery to
     it, in form and substance satisfactory to it, of an affidavit in the form
     of Exhibit I hereto from the proposed transferee.

          (iv)    Notwithstanding the delivery of an affidavit by a proposed
     transferee under clause (iii) above, if a Responsible Officer of the
     Trustee has actual knowledge that the

                                      -71-

<PAGE>

     proposed transferee is not a Permitted Transferee, no transfer of any
     Ownership Interest in a Residual Certificate to such proposed transferee
     shall be effected.

          (v)     No Ownership Interest in a Residual Certificate may be
     purchased by or transferred to any Person that is not a U.S. Person, unless
     (A) such Person holds such Residual Certificate in connection with the
     conduct of a trade or business within the United States and furnishes the
     transferor and the Trustee with an effective Internal Revenue Service Form
     W-8ECI (or successor thereto) or (B) the transferee delivers to both the
     transferor and the Trustee an Opinion of Counsel from 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 a Residual Certificate
     will not be disregarded for federal income tax purposes.

          (vi)    Any attempted or purported transfer of any Ownership Interest
     in a Residual Certificate in violation of the provisions of this Section
     6.02 shall be absolutely null and void and shall vest no rights in the
     purported transferee. If any purported transferee shall, in violation of
     the provisions of this Section 6.02, become a Holder of a Residual
     Certificate, then the prior Holder of such Residual Certificate that is a
     Permitted Transferee shall, upon discovery that the registration of
     transfer of such Residual Certificate was not in fact permitted by this
     Section 6.02, be restored to all rights as Holder thereof retroactive to
     the date of registration of transfer of such Residual Certificate. The
     Trustee shall be under no liability to any Person for any registration of
     transfer of a Residual Certificate that is in fact not permitted by this
     Section 6.02 or for making any distributions due on such Residual
     Certificate to the Holder thereof or taking any other action with respect
     to such Holder under the provisions of the Agreement so long as the
     transfer was registered in accordance with this Section 6.02. The Trustee
     shall be entitled to recover from any Holder of a Residual Certificate that
     was in fact not a Permitted Transferee at the time such distributions were
     made all distributions made on such Residual Certificate. Any such
     distributions so recovered by the Trustee shall be distributed and
     delivered by the Trustee to the prior Holder of such Residual Certificate
     that is a Permitted Transferee.

          (vii)   If any Person other than a Permitted Transferee acquires any
     Ownership Interest in a Residual Certificate in violation of the
     restrictions in this Section 6.02, then the Trustee, based on information
     provided to the Trustee by the Servicer, will provide to the Internal
     Revenue Service, and to the Persons specified in Section 860E(e)(3) and (6)
     of the Code, information needed to compute the tax imposed under Section
     860E(e) of the Code on transfers of residual interests to disqualified
     organizations. The expenses of the Trustee under this clause (vii) shall be
     reimbursable by the Trust.

          (viii)  No Ownership Interest in a Residual Certificate shall be
     acquired by a Plan or any Person acting on behalf of a Plan.

          (g) [Reserved]

          (h) No service charge shall be imposed for any transfer or exchange of
Certificates of any Class, but the Trustee may require payment of a sum
sufficient to cover any

                                      -72-

<PAGE>

tax or governmental charge that may be imposed in connection with any transfer
or exchange of Certificates.

          (i) All Certificates surrendered for transfer and exchange shall be
destroyed by the Certificate Registrar.

          Section 6.03 Mutilated, Destroyed, Lost or Stolen Certificates. If (a)
any mutilated Certificate is surrendered to the Certificate Registrar or the
Certificate Registrar receives evidence to its satisfaction of the destruction,
loss or theft of any Certificate, and (b) there is delivered to the Trustee, the
Depositor and the Certificate Registrar such security or indemnity reasonably
satisfactory to each, to save each of them harmless, then, in the absence of
actual notice to the Trustee or the Certificate Registrar that such Certificate
has been acquired by a bona fide purchaser, the Trustee shall countersign and
deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or
stolen Certificate, a new Certificate of like tenor, Class and Percentage
Interest but bearing a number not contemporaneously outstanding. Upon the
issuance of any new Certificate under this Section, the Trustee may require the
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in relation thereto and any other expenses (including the fees
and expenses of the Trustee and the Certificate Registrar) connected therewith.
Any duplicate Certificate issued pursuant to this Section shall constitute
complete and indefeasible evidence of ownership in the Trust, as if originally
issued, whether or not the lost, stolen or destroyed Certificate shall be found
at any time.

          Section 6.04 Persons Deemed Owners. Prior to due presentation of a
Certificate for registration of transfer, the Depositor, the Servicer, the
Trustee, the Certificate Registrar and any agent of the Depositor, the Servicer,
the Trustee or the Certificate Registrar may treat the Person in whose name any
Certificate is registered as the owner of such Certificate for the purpose of
receiving distributions pursuant to Section 5.01 and for all other purposes
whatsoever, and none of the Depositor, the Servicer, the Trustee, the
Certificate Registrar or any agent of the Servicer, the Trustee or the
Certificate Registrar shall be affected by notice to the contrary.

                                  ARTICLE VII

                         THE DEPOSITOR AND THE SERVICER

          Section 7.01 Respective Liabilities of the Depositor and the Servicer.
The Depositor and the Servicer shall each be liable in accordance herewith only
to the extent of the obligations specifically and respectively imposed upon and
undertaken by the Depositor and the Servicer herein. By way of illustration and
not limitation, the Depositor is not liable for the servicing and administration
of the Mortgage Loans, nor is it obligated by Section 8.01 to assume any
obligations of the Servicer or to appoint a designee to assume such obligations,
nor is it liable for any other obligation hereunder that it may, but is not
obligated to, assume unless it elects to assume such obligation in accordance
herewith.

          Section 7.02 Merger or Consolidation of the Depositor or the Servicer.
The Depositor and the Servicer will each keep in full effect its existence,
rights and franchises as a separate entity under the laws governing its
organization, and will each obtain and preserve its qualification to do business
as a foreign corporation in each jurisdiction in which such

                                      -73-

<PAGE>

qualification is or shall be necessary to protect the validity and
enforceability of this Agreement, the Certificates or any of the Mortgage Loans
and to perform its respective duties under this Agreement.

          Any Person into which the Depositor or the Servicer may be merged or
consolidated, or any corporation resulting from any merger or consolidation to
which the Depositor or the Servicer shall be a party, or any Person succeeding
to the business of the Depositor or the Servicer, shall be the successor of the
Depositor or the Servicer, as the case may be, hereunder, without the execution
or filing of any paper or any further act on the part of any of the parties
hereto, anything herein to the contrary notwithstanding; provided, however, that
the successor or surviving Person to the Servicer shall be qualified to service
mortgage loans on behalf of FNMA or FHLMC.

          Section 7.03 Limitation on Liability of the Depositor, the Servicer
and Others. None of the Depositor, the Servicer or any of the directors,
officers, employees or agents of the Depositor or of the Servicer shall be under
any liability to the Trust Estate or the Certificateholders for any action taken
or for refraining from the taking of any action in good faith pursuant to this
Agreement, or for errors in judgment; provided, however, that this provision
shall not protect the Depositor, the Servicer or any such Person against any
breach of warranties or representations made herein or any liability which would
otherwise be imposed by reason of willful misfeasance, bad faith or gross
negligence in the performance of duties or by reason of reckless disregard of
obligations and duties hereunder. The Depositor, the Servicer and any director,
officer, employee or agent of the Depositor or the Servicer may rely in good
faith on any document of any kind prima facie properly executed and submitted by
any Person respecting any matters arising hereunder. The Depositor, the Servicer
and any director, officer, employee or agent of the Depositor or the Servicer
shall be indemnified by the Trust Estate and held harmless against any loss,
liability or expense incurred in connection with any legal action relating to
this Agreement or the Certificates, other than any loss, liability or expense
related to any specific Mortgage Loan or Mortgage Loans (except as any such
loss, liability or expense shall be otherwise reimbursable pursuant to this
Agreement) and any loss, liability or expense incurred by reason of willful
misfeasance, bad faith or gross negligence in the performance of duties
hereunder or by reason of reckless disregard of obligations and duties
hereunder. Neither of the Depositor nor the Servicer shall be under any
obligation to appear in, prosecute or defend any legal action which is not
incidental to its respective duties under this Agreement and which in its
opinion may involve it in any expense or liability; provided, however, that the
Depositor or the Servicer may in its discretion undertake any such action which
it may deem necessary or desirable in respect to this Agreement and the rights
and duties of the parties hereto and the interests of the Certificateholders
hereunder. In such event, the legal expenses and costs of such action and any
liability resulting therefrom shall be expenses, costs and liabilities of the
Trust Estate, and the Depositor and the Servicer shall be entitled to be
reimbursed therefor out of amounts attributable to the Mortgage Loans on deposit
in the Servicer Custodial Account as provided by Section 3.11.

          Section 7.04 Depositor and Servicer Not to Resign. Subject to the
provisions of Section 7.02, neither the Depositor nor the Servicer shall resign
from its respective obligations and duties hereby imposed on it except upon
determination that its duties hereunder are no longer permissible under
applicable law. Any such determination permitting the resignation of

                                      -74-

<PAGE>

the Depositor or the Servicer shall be evidenced by an Opinion of Counsel to
such effect delivered to the Trustee. No such resignation by the Servicer shall
become effective until the Trustee or a successor Servicer shall have assumed
the Servicer's responsibilities and obligations in accordance with Section 8.05
hereof.

                                  ARTICLE VIII

                                     DEFAULT

          Section 8.01 Events of Default. If any one of the following events
("Events of Default") shall occur and be continuing:

          (a) any failure by the Servicer to deposit amounts in the Servicer
Custodial Account in the amount and manner provided herein so as to enable the
Trustee to distribute to Holders of Certificates any payment required to be made
under the terms of such Certificates and this Agreement (other than the payments
required to be made under Section 3.20) which continues unremedied for a period
of five days; or

          (b) failure on the part of the Servicer duly to observe or perform in
any material respect any other covenants or agreements of the Servicer set forth
in the Certificates or in this Agreement, which covenants and agreements
continue unremedied for a period of 30 days after the date on which written
notice of such failure, requiring the same to be remedied, shall have been given
to the Servicer by the Trustee or the Depositor, or to the Servicer, the
Depositor and the Trustee by the Holders of Certificates evidencing Voting
Rights aggregating not less than 25% of all Certificates affected thereby; or

          (c) the entry of a decree or order by a court or agency or supervisory
authority having jurisdiction in the premises for the appointment of a
conservator, receiver or liquidator in any insolvency, readjustment of debt,
marshalling of assets and liabilities or similar proceedings against the
Servicer, or for the winding up or liquidation of the Servicer's affairs, and
the continuance of any such decree or order unstayed and in effect for a period
of 60 consecutive days; or

          (d) the consent by the Servicer to the appointment of a conservator or
receiver or liquidator in any insolvency, readjustment of debt, marshalling of
assets and liabilities or similar proceedings of or relating to the Servicer or
of or relating to substantially all of its property; or the Servicer shall admit
in writing its inability to pay its debts generally as they become due, file a
petition to take advantage of any applicable insolvency or reorganization
statute, make an assignment for the benefit of its creditors, or voluntarily
suspend payment of its obligations; or

          (e) the failure of the Servicer to remit any Periodic Advance required
to be remitted by the Servicer pursuant to Section 3.20 which failure continues
unremedied at 3:00 p.m. on the related Distribution Date;

then, and in each and every such case, so long as an Event of Default shall not
have been remedied by the Servicer, either the Trustee or the Depositor may, and
at the direction of the Holders of Certificates evidencing Voting Rights
aggregating not less than 51% of all

                                      -75-

<PAGE>

Certificates affected thereby shall, by notice then given in writing to the
Servicer (and to the Trustee, if given by the Depositor, and to the Depositor,
if given by the Trustee), terminate all of the rights and obligations of the
Servicer under this Agreement. If an Event of Default described in clause (e)
hereof shall occur, the Trustee shall, by notice to the Servicer, terminate all
of the rights and obligations of the Servicer under this Agreement and in and to
the Mortgage Loans and proceeds thereof and the Trustee or a successor Servicer
appointed pursuant to Section 8.05 shall make the Advance which the Servicer
failed to make. On or after the receipt by the Servicer of such written notice,
all authority and power of the Servicer under this Agreement, whether with
respect to the Certificates or the Mortgage Loans or otherwise, shall pass to
and be vested in the Trustee pursuant to and under this Section 8.01, unless and
until such time as the Trustee shall appoint a successor Servicer pursuant to
Section 8.05, and, without limitation, the Trustee is hereby authorized and
empowered to execute and deliver, on behalf of the Servicer, as attorney-in-fact
or otherwise, any and all documents and other instruments, and to do or
accomplish all other acts or things necessary or appropriate to effect the
purposes of such notice of termination, whether to complete the transfer and
endorsement of the Mortgage Loans and related documents, or otherwise,
including, without limitation, the recordation of the assignments of the
Mortgage Loans to it. The Servicer agrees to cooperate with the Trustee in
effecting the termination of the responsibilities and rights of the Servicer
hereunder, including, without limitation, the transfer to the Trustee for the
administration by it of all cash amounts that have been deposited by the
Servicer in the Servicer Custodial Account or thereafter received by the
Servicer with respect to the Mortgage Loans. Upon obtaining notice or knowledge
of the occurrence of any Event of Default, the Person obtaining such notice or
knowledge shall give prompt written notice thereof to Certificateholders at
their respective addresses appearing in the Certificate Register and to each
Rating Agency. All costs and expenses (including attorneys' fees) incurred in
connection with transferring the Mortgage Files to the successor Servicer and
amending this Agreement to reflect such succession as Servicer pursuant to this
Section 8.01 shall be paid by the predecessor Servicer. Notwithstanding the
termination of the Servicer pursuant hereto, the Servicer shall remain liable
for any causes of action arising out of any Event of Default occurring prior to
such termination.

          Section 8.02 Remedies of Trustee. During the continuance of any Event
of Default, so long as such Event of Default shall not have been remedied, the
Trustee, in addition to the rights specified in Section 8.01, shall have the
right, in its own name as trustee of an express trust, to take all actions now
or hereafter existing at law, in equity or by statute to enforce its rights and
remedies and to protect the interests, and enforce the rights and remedies, of
the Certificateholders (including the institution and prosecution of all
judicial, administrative and other proceedings and the filing of proofs of claim
and debt in connection therewith). Except as otherwise expressly provided in
this Agreement, no remedy provided for by this Agreement shall be exclusive of
any other remedy, and each and every remedy shall be cumulative and in addition
to any other remedy and no delay or omission to exercise any right or remedy
shall impair any such right or remedy or shall be deemed to be a waiver of any
Event of Default.

          Section 8.03 Directions by Certificateholders and Duties of Trustee
During Event of Default. During the continuance of any Event of Default, Holders
of Certificates evidencing Voting Rights aggregating not less than 25% of each
Class of Certificates affected thereby 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 under this

                                      -76-

<PAGE>

Agreement; provided, however, that the Trustee shall be under no obligation to
pursue any such remedy, or to exercise any of the trusts or powers vested in it
by this Agreement (including, without limitation, (a) the conducting or
defending of any administrative action or litigation hereunder or in relation
hereto, and (b) the terminating of the Servicer or any successor Servicer from
its rights and duties as servicer hereunder) at the request, order or direction
of any of the Certificateholders, unless such Certificateholders shall have
offered to the Trustee reasonable security or indemnity against the costs,
expenses and liabilities which may be incurred therein or thereby and, provided
further, that, subject to the provisions of Section 9.01, the Trustee shall have
the right to decline to follow any such direction if the Trustee, based upon an
Opinion of Counsel, determines that the action or proceeding so directed may not
lawfully be taken or if the Trustee in good faith determines that the action or
proceeding so directed would involve it in personal liability or be unjustly
prejudicial to the non-assenting Certificateholders.

          Section 8.04 Action upon Certain Failures of the Servicer and upon
Event of Default. In the event that the Trustee shall have actual knowledge of
any failure of the Servicer specified in Section 8.01(a) or (b) which would
become an Event of Default upon the Servicer's failure to remedy the same after
notice, the Trustee shall give notice thereof to the Servicer. If the Trustee
shall have knowledge of an Event of Default, the Trustee shall give prompt
written notice thereof to the Certificateholders.

          Section 8.05 Trustee to Act; Appointment of Successor.

          (a) On and after the time the Servicer receives a notice of
termination pursuant to Section 8.01, the Trustee shall be the successor in all
respects to the Servicer in its capacity as servicer under this Agreement and
the transactions set forth or provided for herein and shall be subject to all
the responsibilities, duties and liabilities relating thereto placed on the
Servicer by the terms and provisions hereof or shall appoint a successor
pursuant to Section 3.07. Notwithstanding anything provided herein to the
contrary, under no circumstances shall any provision of this Agreement be
construed to require the Trustee, acting in its capacity as successor to the
Servicer in its obligation to make Advances, to advance, expend or risk its own
funds or otherwise incur any financial liability in the performance of its
duties hereunder if it shall have reasonable grounds for believing that such
funds are non-recoverable. Subject to Section 8.05(b), as compensation therefor,
the Trustee shall be entitled to such compensation as the terminated Servicer
would have been entitled to hereunder if no such notice of termination had been
given. Notwithstanding the above, the Trustee may, if it shall be unwilling so
to act, or shall, if it is legally unable so to act, appoint, or petition a
court of competent jurisdiction to appoint, any established housing and home
finance institution having a net worth of not less than $10,000,000 as the
successor to the terminated Servicer hereunder in the assumption of all or any
part of the responsibilities, duties or liabilities of the Servicer hereunder;
provided, however, that any such institution appointed as successor Servicer
shall not, as evidenced in writing by each Rating Agency, adversely affect the
then current rating of any Class of Certificates immediately prior to the
termination of the terminated Servicer. The appointment of a successor Servicer
shall not affect any liability of the predecessor Servicer which may have arisen
under this Agreement prior to its termination as Servicer, nor shall any
successor Servicer be liable for any acts or omissions of the predecessor
Servicer or for any breach by the Servicer of any of its representations or
warranties contained herein or in any related document or agreement. Pending
appointment of a successor to the terminated Servicer hereunder, unless the
Trustee is prohibited

                                      -77-

<PAGE>

by law from so acting, the Trustee shall act in such capacity as provided above.
The Trustee and such successor shall take such action, consistent with this
Agreement, as shall be necessary to effectuate any such succession.

          (b) In connection with the appointment of a successor Servicer or the
assumption of the duties of the Servicer, as specified in Section 8.05(a), the
Trustee may make such arrangements for the compensation of such successor out of
payments on Mortgage Loans serviced by the predecessor Servicer as it and such
successor shall agree; provided, however, that any Person assuming the duties of
the Servicer shall pay to such predecessor an amount equal to the market value
of the portion of the Servicing Fee that will accrue in the future due to the
Servicing Fee Rate exceeding     % per annum with respect to any Mortgage Loan.
The "market value" of such portion of the Servicing Fee shall be determined by
Bank of America, N.A., on the basis of at least two quotations from third
parties actively engaged in the servicing of single-family mortgage loans. If
the successor Servicer does not agree that such market value is a fair price,
such successor shall obtain two quotations of market value from third parties
actively engaged in the servicing of single-family mortgage loans. The market
value of the excess portion of the Servicing Fee will then be equal to the
average of (i) the lowest figure obtained by Bank of America, N.A., and (ii) the
highest figure obtained by the successor Servicer. Payment of the amount
calculated above shall be made to Bank of America, N.A., by the successor
Servicer no later than the last Business Day of the month in which such
successor Servicer becomes entitled to receive the Servicing Fee under this
Agreement. In no event will any portion of the Trust Estate be used to pay
amounts due to Bank of America, N.A. under this Section 8.05(b).

          (c) Any successor, including the Trustee, to the Servicer as servicer
shall during the term of its service as servicer maintain in force (i) a policy
or policies of insurance covering errors and omissions in the performance of its
obligations as servicer hereunder and (ii) a fidelity bond in respect of its
officers, employees and agents to the same extent as the Servicer is so required
pursuant to Section 3.03.

          Section 8.06 Notification to Certificateholders. Upon any termination
or appointment of a successor to the Servicer pursuant to this Article VIII, the
Trustee shall give prompt written notice thereof to Certificateholders at their
respective addresses appearing in the Certificate Register and to each Rating
Agency.

                                   ARTICLE IX

                                   THE TRUSTEE

          Section 9.01 Duties of Trustee.

          (a) The Trustee, prior to the occurrence of an Event of Default and
after the curing or waiver of all Events of Default which may have occurred,
undertakes to perform such duties and only such duties as are specifically set
forth in this Agreement. In case an Event of Default has occurred of which a
Responsible Officer of the Trustee shall have actual knowledge (which has not
been cured or waived), the Trustee shall exercise such of the rights and powers
vested in it by this Agreement, and use the same degree of care and skill in
their exercise as a

                                      -78-

<PAGE>

reasonably prudent investor would exercise or use under the circumstances in the
conduct of such investor's own affairs.

          The Trustee, upon receipt of all resolutions, certificates,
statements, opinions, reports, documents, orders or other instruments furnished
to the Trustee which are specifically required to be furnished pursuant to any
provision of this Agreement, shall examine them to determine whether they
conform to the requirements of this Agreement.

          (b) No provision of this Agreement shall be construed to relieve the
Trustee from liability for its own grossly negligent action, its own grossly
negligent failure to act or its own willful misfeasance; provided, however,
that:

          (i)     Prior to the occurrence of an Event of Default, and after the
     curing or waiver of all such Events of Default which may have occurred, the
     duties and obligations of the Trustee shall be determined solely by the
     express provisions of this Agreement, the Trustee shall not be liable
     except for the performance of such duties and obligations as are
     specifically set forth in this Agreement, no implied covenants or
     obligations shall be read into this Agreement against the Trustee and, in
     the absence of bad faith on the part of the Trustee, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon any certificates or opinions furnished
     to the Trustee by the Depositor or the Servicer and which on their face, do
     not contradict the requirements of this Agreement;

          (ii)    The Trustee (in its individual capacity) shall not be
     personally liable for an error of judgment made in good faith by a
     Responsible Officer or Responsible Officers of the Trustee, unless it shall
     be proved that the Trustee was grossly negligent in ascertaining the
     pertinent facts;

          (iii)   The Trustee (in its individual capacity) shall not be
     personally liable with respect to any action taken, suffered or omitted to
     be taken by it in good faith in accordance with the direction of
     Certificateholders as provided in Section 8.03;

          (iv)    The Trustee shall not be charged with knowledge of any default
     (other than a default in payment to the Trustee) specified in clauses (a)
     and (b) of Section 8.01 or an Event of Default under clauses (c), (d) and
     (e) of Section 8.01 unless a Responsible Officer of the Trustee assigned to
     and working in the Corporate Trust Office obtains actual knowledge of such
     failure or event or any officer of the Trustee receives written notice of
     such failure or event at its Corporate Trust Office from the Servicer, the
     Depositor or any Certificateholder; and

          (v)     Except to the extent provided in Section 8.05, no provision in
     this Agreement shall require the Trustee to expend or risk its own funds
     (including, without limitation, the making of any Advance as successor
     Servicer) or otherwise incur any personal financial liability in the
     performance of any of its duties as Trustee hereunder, or in the exercise
     of any of its rights or powers, if the Trustee shall have reasonable
     grounds for believing that repayment of funds or adequate indemnity against
     such risk or liability is not reasonably assured to it.

          Section 9.02 Certain Matters Affecting the Trustee.

          Except as otherwise provided in Section 9.01:

          (i)     The Trustee may request and rely upon and shall be protected
     in acting or refraining from acting upon any resolution, Officer's
     Certificate, certificate of auditors or any other certificate, statement,
     instrument, opinion, report, notice, request, consent, order, appraisal,
     bond or other paper or document believed by it to be genuine and to have
     been signed or presented by the proper party or parties;

          (ii)    The Trustee may consult with counsel and any Opinion of
     Counsel shall be full and complete authorization and protection in respect
     of any action taken or suffered or omitted by it hereunder in good faith
     and in accordance with such Opinion of Counsel;

          (iii)   The Trustee shall be under no obligation to exercise any of
     the trusts or powers vested in it by this Agreement or to institute,
     conduct or defend any litigation hereunder or in relation hereto at the
     request, order or direction of any of the Certificateholders, pursuant to
     the provisions of this Agreement, unless such Certificateholders shall have
     offered to the Trustee reasonable security or indemnity against the costs,
     expenses and liabilities which may be incurred therein or thereby; nothing
     contained herein shall, however, relieve the Trustee of the obligation,
     upon the occurrence of an Event of Default (which has not been cured or
     waived), to exercise such of the rights and powers vested in it by this
     Agreement, and to use the same degree of care and skill in their exercise
     as a prudent investor would exercise or use under the circumstances in the
     conduct of such investor's own affairs;

          (iv)    The Trustee shall not be personally liable for any action
     taken, suffered or omitted by it in good faith and believed by it to be
     authorized or within the discretion or rights or powers conferred upon it
     by this Agreement;

          (v)     Prior to the occurrence of an Event of Default hereunder and
     after the curing or waiving of all Events of Default which may have
     occurred, the Trustee shall not be bound to make any investigation into the
     facts or matters stated in any resolution, certificate, statement,
     instrument, opinion, report, notice, request, consent, order, approval,
     bond or other paper or document, unless requested in writing so to do by
     Holders or Certificate or any Class evidencing, as to such Class,
     Percentage Interests, aggregating not less than 50%; provided, however,
     that if the payment within a reasonable time to the Trustee of the costs,
     expenses or liabilities likely to be incurred by it in the making of such
     investigation is, in the opinion of the Trustee, not reasonably assured to
     the Trustee by the security afforded to it by the terms of this Agreement,
     the Trustee may require reasonable indemnity against such expense or
     liability or payment of such estimated expenses as a condition to so
     proceeding; and

          (vi)    The Trustee may execute any of the trusts or powers hereunder
     or perform any duties hereunder either directly or by or through agents or
     attorneys.

          Section 9.03 Trustee Not Liable for Certificates or Mortgage Loans.
The recitals contained herein and in the Certificates (other than the execution
of, and the counter-

                                      -80-

<PAGE>

signature on the Certificates) shall be taken as the statements of the Depositor
or Servicer, as applicable, and the Trustee assumes no responsibility for their
correctness. The Trustee makes no representations as to the validity or
sufficiency of this Agreement or of the Certificates or any Mortgage Loans save
that the Trustee represents that, assuming due execution and delivery by the
other parties hereto, this Agreement has been duly authorized, executed and
delivered by it and constitutes its legal, valid and binding obligation,
enforceable against it in accordance with its terms, subject, as to enforcement
of remedies, to applicable insolvency, receivership, moratorium and other laws
affecting the rights of creditors generally, and to general principles of equity
and the discretion of the court (regardless of whether enforcement of such
remedies is considered in a proceeding in equity or at law). The Trustee shall
not be accountable for the use or application by the Depositor of funds paid to
the Depositor in consideration of the assignment of the Mortgage Loans hereunder
by the Depositor, or for the use or application of any funds paid to
Subservicers or the Servicer in respect of the Mortgage Loans or deposited into
the Servicer Custodial Account, or any other account hereunder (other than the
Certificate Account) by the Servicer.

          The Trustee shall at no time have any responsibility or liability for
or with respect to the legality, validity and enforceability of any Mortgage or
any Mortgage Loan, or the perfection and priority of any Mortgage or the
maintenance of any such perfection and priority or for or with respect to the
sufficiency of the Trust or its ability to generate the payments to be
distributed to Certificateholders under this Agreement, including, without
limitation: the existence, condition and ownership of any Mortgaged Property;
the existence and enforceability of any hazard insurance thereon (other than if
the Trustee shall assume the duties of the Servicer pursuant to Section 8.05 and
thereupon only for the acts or omissions of the successor Servicer); the
validity of the assignment of any Mortgage Loan to the Trustee or of any
intervening assignment; the completeness of any Mortgage Loan; the performance
or enforcement of any Mortgage Loan (other than if the Trustee shall assume the
duties of the Servicer pursuant to Section 8.05 and thereupon only for the acts
or omissions of the Trustee as successor Servicer); the compliance by the
Depositor or the Servicer with any warranty or representation made under this
Agreement or in any related document or the accuracy of any such warranty or
representation; any investment of monies by or at the direction of the Servicer
or any loss resulting therefrom, it being understood that the Trustee shall
remain responsible for any Trust property that it may hold in its individual
capacity; the acts or omissions of any of the Depositor, the Servicer (other
than if the Trustee shall assume the duties of the Servicer pursuant to Section
8.05 and thereupon only for the acts or omissions of the Trustee as successor
Servicer), any Subservicer or any Mortgagor; any action of the Servicer (other
than if the Trustee shall assume the duties of the Servicer pursuant to Section
8.05 and thereupon only for the acts or omissions of the Trustee as successor
Servicer) or any Subservicer taken in the name of the Trustee; the failure of
the Servicer or any Subservicer to act or perform any duties required of it as
agent of the Trustee hereunder; or any action by the Trustee taken at the
instruction of the Servicer (other than if the Trustee shall assume the duties
of the Servicer pursuant to Section 8.05 and thereupon only for the acts or
omissions of the Trustee as successor Servicer); provided, however, that the
foregoing shall not relieve the Trustee of its obligation to perform its duties
under this Agreement, including, without limitation, the Trustee's review of the
Mortgage Files pursuant to Section 2.02. The Trustee shall file any financing or
continuation statement in any public office at any time required to maintain the
perfection of any security interest or lien granted to it hereunder.

          Section 9.04 Trustee May Own Certificates. The Trustee in its
individual or any other capacity may become the owner or pledgee of Certificates
with the same rights it would have if it were not Trustee and may otherwise deal
with the Servicer, any Subservicer or any of their respective affiliates with
the same right it would have if it were not the Trustee.

          Section 9.05 Eligibility Requirements for Trustee. The Trustee
hereunder shall at all times be (a) an institution the deposits of which are
fully insured by the FDIC and (b) a corporation or banking association organized
and doing business under the laws of the United States of America or of any
State, authorized under such laws to exercise corporate trust powers, having a
combined capital and surplus of not less than $50,000,000 and subject to
supervision or examination by Federal or State authority and (c) with respect to
every successor trustee hereunder either an institution (i) the long-term
unsecured debt obligations of which are rated at least "  " by      and      or
(ii) whose serving as Trustee hereunder would not result in the lowering of the
ratings originally assigned to any Class of Certificates. The Trustee shall not
be an affiliate of the Depositor or the Servicer. If such corporation or banking
association publishes reports of condition at least annually, pursuant to law or
to the requirements of the aforesaid supervising or examining authority, then
for the purposes of this Section 9.05, the combined capital and surplus of such
corporation or banking association shall be deemed to be its combined capital
and surplus as set forth in its most recent report of condition so published. In
case at any time the Trustee shall cease to be eligible in accordance with the
provision of this Section 9.05, the Trustee shall resign immediately in the
manner and with the effect specified in Section 9.06.

          Section 9.06 Resignation and Removal of Trustee. The Trustee may at
any time resign and be discharged from the trust hereby created by giving
written notice thereof to the Servicer and mailing a copy of such notice to all
Holders of record. The Trustee shall also mail a copy of such notice of
resignation to each Rating Agency. Upon receiving such notice of resignation,
the Servicer shall use their best efforts to promptly appoint a mutually
acceptable successor Trustee by written instrument, in duplicate, one copy of
which instrument shall be delivered to the resigning Trustee and one copy to the
successor Trustee. If no successor Trustee shall have been so appointed and
shall have accepted appointment within 30 days after the giving of such notice
of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee.

          If at any time the Trustee shall cease to be eligible in accordance
with the provisions of Section 9.05 and shall fail to resign after written
request therefor by the Servicer, or if at any time the Trustee shall become
incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver
of the Trustee or of its property shall be appointed, or any public officer
shall take charge or control of the Trustee or of its property or affairs for
the purpose of rehabilitation, conservation or liquidation, then the Servicer
may remove the Trustee and appoint a successor trustee by written instrument, in
duplicate, one copy of which instrument shall be delivered to the Trustee so
removed and one copy to the successor.

          The Holders of Certificates evidencing not less than 50% of the Voting
Rights may at any time remove the Trustee by written instrument or instruments
delivered to the Servicer and the Trustee; the Servicer shall thereupon use
their best efforts to appoint a mutually acceptable successor Trustee in
accordance with this Section 9.06.

                                      -82-

<PAGE>

          Any resignation or removal of the Trustee and appointment of a
successor Trustee pursuant to any of the provisions of this Section 9.06 shall
become effective upon acceptance of appointment by the successor Trustee as
provided in Section 9.07.

          Section 9.07 Successor Trustee. Any successor Trustee appointed as
provided in Section 9.06 shall execute, acknowledge and deliver to the Servicer
and to its predecessor Trustee an instrument accepting such appointment
hereunder, and thereupon the resignation or removal of the predecessor Trustee
shall become effective and such successor Trustee, without any further act, deed
or conveyance, shall become fully vested with all the rights, powers, duties and
obligations of its predecessor hereunder, with like effect as if originally
named as Trustee herein. The predecessor Trustee shall duly assign, transfer,
deliver and pay over to the successor Trustee the whole of the Mortgage Files
and related documents and statements held by it hereunder, together with all
instruments of transfer and assignment or other documents properly executed as
may be reasonably required to effect such transfer and such of the records or
copies thereof maintained by the predecessor Trustee in the administration
hereof as may be reasonably requested by the successor Trustee and shall
thereupon be discharged from all duties and responsibilities under this
Agreement; provided, however, that if the predecessor Trustee has been
terminated pursuant to the third paragraph of Section 9.06, all reasonable
expenses of the predecessor Trustee incurred in complying with this Section 9.07
shall be reimbursed by the Trust.

          No successor Trustee shall accept appointment as provided in this
Section 9.07 unless at the time of such appointment such successor Trustee shall
be eligible under the provisions of Section 9.05.

          Upon acceptance of appointment by a successor Trustee as provided in
this Section 9.07, the Servicer shall cooperate to mail notice of the succession
of such Trustee hereunder to all Holders of Certificates at their addresses as
shown in the Certificate Register and to each Rating Agency. If the Servicer
fail to mail such notice within ten days after acceptance of appointment by the
successor Trustee, the successor Trustee shall cause such notice to be mailed at
the expense of the Servicer.

          Section 9.08 Merger or Consolidation of Trustee. Any corporation or
banking association into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation or banking association
resulting from any merger, conversion or consolidation to which the Trustee
shall be a party, or any corporation or banking association succeeding to all or
substantially all of the corporate trust business of the Trustee, shall be the
successor of the Trustee hereunder, if such corporation or banking association
is eligible under the provisions of Section 9.05, without the execution or
filing of any paper or any further act on the part of any of the parties hereto,
anything herein to the contrary notwithstanding.

          Section 9.09 Appointment of Co-Trustee or Separate Trustee.
Notwithstanding any of the provisions hereof, at any time, for the purpose of
meeting any legal requirements of any jurisdiction in which any Mortgaged
Property may at the time be located or for any other reason, the Servicer and
the Trustee acting jointly shall have the power and shall execute and deliver
all instruments to appoint one or more Persons approved by the Trustee as
co-trustee or separate trustee of all or any part of the Trust Estate, and to
vest in such Person or Persons, in

                                      -83-

<PAGE>

such capacity, such title to the Trust Estate, or any part thereof, and, subject
to the other provision of this Section 9.09, such powers, duties, obligations,
rights and trusts as the Servicer and the Trustee may consider necessary or
desirable. If the Servicer shall not have joined in such appointment within ten
days after the receipt by it of a request to do so, the Trustee alone shall have
the power to make such appointment. No co-trustee or separate trustee hereunder
shall be required to meet the terms of eligibility as a successor Trustee under
Section 9.05 and no notice to Holders of Certificates of the appointment of
co-trustee(s) or separate trustee(s) shall be required under Section 9.07.

          In the case of any appointment of a co-trustee or separate trustee
pursuant to this Section 9.09, all rights, powers, duties and obligations
conferred or imposed upon the Trustee shall be conferred or imposed upon and
exercised or performed by the Trustee and such separate trustee or co-trustee
jointly, except to the extent that under any law of any jurisdiction in which
any particular act or acts are to be performed (whether as Trustee hereunder or
as successor to the Servicer hereunder), the Trustee shall be incompetent or
unqualified to perform such act or acts, in which event such rights, powers,
duties and obligations (including the holding of title to the Trust Estate or
any portion thereof in any such jurisdiction) shall be exercised and performed
by such separate trustee or co-trustee at the direction of the Trustee. No
trustee hereunder shall be held personally liable by reason of any act or
omission of any other trustee hereunder; provided, however, that no appointment
of a co-trustee or separate trustee hereunder shall relieve the Trustee of its
obligations hereunder.

          Any notice, request or other writing given to the Trustee shall be
deemed to have been given to each of the then separate trustees and co-trustees,
as effectively as if given to each of them. Every instrument appointing any
separate trustee or co-trustee shall refer to this Agreement and the conditions
of this Article IX. Each separate trustee and co-trustee, upon its acceptance of
the trusts conferred, shall be vested with the estates or property specified in
its instrument of appointment, either jointly with the Trustee or separately, as
may be provided therein, subject to all the provisions of this Agreement,
specifically including every provision of this Agreement relating to the conduct
of, affecting the liability of, or affording protection to, the Trustee. Every
such instrument shall be filed with the Trustee.

          Any separate trustee or co-trustee may, at any time, constitute the
Trustee, its agent or attorney-in-fact, with full power and authority, to the
extent not prohibited by law, to do any lawful act under or in respect of this
Agreement on its behalf and in its name. If any separate trustee or co-trustee
shall become incapable of acting, resign or be removed, or shall be adjudged a
bankrupt or insolvent, or a receiver of its property shall be appointed, or any
public officer shall take charge or control of such trustee or co-trustee or of
its property or affairs for the purpose of rehabilitation, conservation or
liquidation, all of its estates, properties, rights, remedies and trusts shall
vest in and be exercised by the Trustee, to the extent permitted by law, without
the appointment of a new or successor trustee.

          Section 9.10 Authenticating Agents. The Trustee may appoint one or
more authenticating agents ("Authenticating Agents") which shall be authorized
to act on behalf of the Trustee in authenticating or countersigning
Certificates. Initially, the Authenticating Agent shall be      . Wherever
reference is made in this Agreement to the authentication or

                                      -84-

<PAGE>

countersigning of Certificates by the Trustee or the Trustee's certificate of
authentication or countersigning, such reference shall be deemed to include
authentication or countersigning on behalf of the Trustee by an Authenticating
Agent and a certificate of authentication or countersignature executed on behalf
of the Trustee by an Authenticating Agent. Each Authenticating Agent must be
acceptable to the Servicer and must be a corporation or banking association
organized and doing business under the laws of the United States of America or
of any State, having a principal office and place of business in New York, New
York, having a combined capital and surplus of at least $15,000,000, authorized
under such laws to do a trust business and subject to supervision or examination
by Federal or State authorities.

          Any corporation or banking association into which any Authenticating
Agent may be merged or converted or with which it may be consolidated, or any
corporation or banking association resulting from any merger, conversion or
consolidation to which any Authenticating Agent shall be a party, or any
corporation or banking association succeeding to the corporate agency business
of any Authenticating Agent, shall continue to be the Authenticating Agent
without the execution or filing of any paper or any further act on the part of
the Trustee or the Authenticating Agent.

          Any Authenticating Agent may at any time resign by giving written
notice of resignation to the Trustee and to the Servicer. The Trustee may at any
time terminate the agency of any Authenticating Agent by giving written notice
of termination to such Authenticating Agent and to the Servicer. Upon receiving
a notice of resignation or upon such a termination, or in case, at any time any
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section 9.10, the Trustee may appoint a successor
Authenticating Agent, shall give written notice of such appointment to the
Servicer and shall mail notice of such appointment to all Certificateholders.
Any successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers, duties and responsibilities of
its predecessor hereunder, with like effect as if originally named as
Authenticating Agent.

          Section 9.11 Trustee's Fees and Expenses. The Trustee, as compensation
for its activities hereunder, shall be entitled to receive on each Distribution
Date an amount equal to the Trustee Fee for such Distribution Date pursuant to
Section 5.02(a). The Trustee and any director, officer, employee or agent of the
Trustee shall be indemnified by the Trust and held harmless against any loss,
liability or expense (including reasonable attorney's fees) (a) incurred in
connection with any claim or legal action relating to (i) this Agreement, (ii)
the Certificates, or (iii) the performance of any of the Trustee's duties
hereunder, other than any loss, liability or expense incurred by reason of
willful misfeasance, bad faith or gross negligence in the performance of any of
the Trustee's duties hereunder, (b) resulting from any tax or information return
which was prepared by, or should have been prepared by, the Servicer and (c)
arising out of the transfer of any Private Certificate not in compliance with
ERISA. Such indemnity shall survive the termination of this Agreement or the
resignation or removal of the Trustee hereunder. Without limiting the foregoing,
except as otherwise agreed upon in writing by the Depositor and the Trustee, and
except for any such expense, disbursement or advance as may arise from the
Trustee's gross negligence, bad faith or willful misconduct, the Trust shall
reimburse the Trustee for all reasonable expenses, disbursements and advances
incurred or made by the Trustee in accordance with any of the provisions of this
Agreement to the extent permitted by Treasury Regulations Section
1.860G-1(b)(3)(ii) and (iii); provided, however, that the Depositor and the

                                      -85-

<PAGE>

Trustee intend to enter into a separate agreement for custody-related services.
Except as otherwise provided herein, the Trustee shall not be entitled to
payment or reimbursement for any routine ongoing expenses incurred by the
Trustee in the ordinary course of its duties as Trustee, Certificate Registrar
or Paying Agent hereunder or for any other expenses.

          Section 9.12 Appointment of Custodian. The Trustee may at any time on
or after the Closing Date, with the consent of the Depositor and the Servicer,
appoint one or more Custodians to hold all or a portion of the Mortgage Files as
agent for the Trustee, by entering into a custodial agreement in a form
acceptable to the Depositor and the Servicer. Subject to this Article IX, the
Trustee agrees to comply with the terms of each Custodial Agreement and to
enforce the terms and provisions thereof against the Custodian for the benefit
of the Certificateholders. Each Custodian shall be a depository institution
subject to supervision by federal or state authority, shall have a combined
capital and surplus of at least $10,000,000 and shall be qualified to do
business in the jurisdiction in which it holds any Mortgage File.

          Section 9.13 Paying Agents. The Trustee may appoint one or more Paying
Agents (each, a "Paying Agent") which shall be authorized to act on behalf of
the Trustee in making withdrawals from the Certificate Account and distributions
to Certificateholders as provided in Section 3.08 and Section 5.02. Wherever
reference is made in this Agreement to the withdrawal from the Certificate
Account by the Trustee, such reference shall be deemed to include such a
withdrawal on behalf of the Trustee by a Paying Agent. Initially, the Paying
Agent shall be               . Whenever reference is made in this Agreement to a
distribution by the Trustee or the furnishing of a statement to
Certificateholders by the Trustee, such reference shall be deemed to include
such a distribution or furnishing on behalf of the Trustee by a Paying Agent.
Each Paying Agent shall provide to the Trustee such information concerning the
Certificate Account as the Trustee shall request from time to time. Each Paying
Agent must be reasonably acceptable to the Servicer and must be a corporation or
banking association organized and doing business under the laws of the United
States of America or of any state, having (except in the case of the Trustee) a
principal office and place of business in New York, New York, having a combined
capital and surplus of at least $15,000,000, authorized under such laws to do a
trust business and subject to supervision or examination by federal or state
authorities.

          Any corporation into which any Paying Agent may be merged or converted
or with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which any Paying Agent shall be a party,
or any corporation succeeding to the corporate agency business of any Paying
Agent, shall continue to be the Paying Agent provided that such corporation
after the consummation of such merger, conversion, consolidation or succession
meets the eligibility requirements of this Section 9.13.

          Any Paying Agent may at any time resign by giving written notice of
resignation to the Trustee and to the Servicer; provided that the Paying Agent
has returned to the Certificate Account or otherwise accounted, to the
reasonable satisfaction of the Trustee, for all amounts it has withdrawn from
the Certificate Account. The Trustee may, upon prior written approval of the
Servicer, at any time terminate the agency of any Paying Agent by giving written
notice of termination to such Paying Agent and to the Servicer. Upon receiving a
notice of resignation or upon such a termination, or in case at any time any
Paying Agent shall cease to be eligible in

                                      -86-

<PAGE>

accordance with the provisions of the first paragraph of this Section 9.13, the
Trustee may appoint, upon prior written approval of the Servicer, a successor
Paying Agent, shall give written notice of such appointment to the Servicer and
shall mail notice of such appointment to all Certificateholders. Any successor
Paying Agent upon acceptance of its appointment hereunder shall become vested
with all rights, powers, duties and responsibilities of its predecessor
hereunder, with like effect as if originally named as Paying Agent. The Trustee
shall remain liable for any duties and obligations assumed by its appointed
Paying Agent.

          Section 9.14 Limitation of Liability. The Certificates are executed by
the Trustee, not in its individual capacity but solely as Trustee of the Trust,
in the exercise of the powers and authority conferred and vested in it by this
Agreement. Each of the undertakings and agreements made on the part of the
Trustee in the Certificates is made and intended not as a personal undertaking
or agreement by the Trustee but is made and intended for the purpose of binding
only the Trust.

          Section 9.15 Trustee May Enforce Claims Without Possession of
Certificates. All rights of action and claims under this Agreement or the
Certificates may be prosecuted and enforced by the Trustee without the
possession of any of the Certificates or the production thereof in any
proceeding relating thereto, and such preceding instituted by the Trustee shall
be brought in its own name or in its capacity as Trustee. Any recovery of
judgment shall, after provision for the payment of the reasonable compensation,
expenses, disbursement and advances of the Trustee, its agents and counsel, be
for the ratable benefit of the Certificateholders in respect of which such
judgment has been recovered.

          Section 9.16 Suits for Enforcement. In case an Event of Default or
other default by the Servicer or the Depositor hereunder shall occur and be
continuing, the Trustee, in its discretion, may proceed to protect and enforce
its rights and the rights of the Holders of Certificates under this Agreement by
a suit, action or proceeding in equity or at law or otherwise, whether for the
specific performance of any covenant or agreement contained in this Agreement or
in aid of the execution of any power granted in this Agreement or for the
enforcement of any other legal, equitable or other remedy, as the Trustee, being
advised by counsel, shall deem most effectual to protect and enforce any of the
rights of the Trustee and the Certificateholders.

          Section 9.17 Waiver of Bond Requirement. The Trustee shall be relieved
of, and each Certificateholder hereby waives, any requirement of any
jurisdiction in which the Trust, or any part thereof, may be located that the
Trustee post a bond or other surety with any court, agency or body whatsoever.

          Section 9.18 Waiver of Inventory, Accounting and Appraisal
Requirement. The Trustee shall be relieved of, and each Certificateholder hereby
waives, any requirement of any jurisdiction in which the Trust, or any part
thereof, may be located that the Trustee file any inventory, accounting or
appraisal of the Trust with any court, agency or body at any time or in any
manner whatsoever.

any Mortgage Loan as to which REO Property has been acquired and whose fair
market value is included pursuant to clause (ii) below) and (ii) the fair market
value of such REO Property (as determined by the Depositor as of the close of
business on the third Business Day next preceding the date upon which notice of
any such termination is furnished to Certificateholders pursuant to the fourth
paragraph of this Article X), plus any Class Unpaid Interest Shortfall for any
Class of Certificates as well as one month's interest at the related Mortgage
Rate on the Stated Principal Balance of each Mortgage Loan (including any
Mortgage Loan as to which REO Property has been acquired) or (b) the final
payment or other liquidation (or any advance with respect thereto) of the last
Mortgage Loan remaining in the Trust Estate or the disposition of all REO
Property.

          Regardless of the foregoing, in no event shall the Trust created
hereby continue beyond the expiration of 21 years from the death of the last
survivor of the descendants of Joseph P. Kennedy, the late ambassador of the
United States to the Court of St. James, living on the date hereof.

          The right of the Depositor to repurchase all of the Mortgage Loans is
conditioned upon the Pool Stated Principal Balance as of the Final Distribution
Date being less than 1% of the Cut-off Date Pool Principal Balance. If such
right is exercised, the Trustee shall, promptly following payment of the
purchase price, release to the Depositor or its designee the Mortgage Files
pertaining to the Mortgage Loans being purchased.

          Notice of any termination, specifying the Final Distribution Date
(which shall be a date that would otherwise be a Distribution Date) upon which
the Certificateholders may surrender their Certificates to the Trustee for
payment of the final distribution and for cancellation, shall be given promptly
by the Depositor (if exercising its right to purchase the assets of the Trust)
or by the Trustee (in any other case) by letter to Certificateholders mailed not
earlier than the 15th day and not later than the 20th day of the month next
preceding the month of such final distribution specifying (1) the Final
Distribution Date upon which final payment of the Certificates will be made upon
presentation and surrender of Certificates at the office or agency of the
Trustee therein designated, (2) the amount of any such final payment and (3)
that the Record Date otherwise applicable to such Distribution Date is not
applicable, payments being made only upon presentation and surrender of the
Certificates at the office or agency of the Trustee therein specified. If the
Depositor is obligated to give notice to Certificateholders as aforesaid, it
shall give such notice to the Trustee and the Certificate Registrar at the time
such

                                      -88-

<PAGE>

notice is given to Certificateholders. In the event such notice is given by the
Depositor, the Depositor shall deposit in the Certificate Account on or before
the Final Distribution Date in immediately available funds an amount equal to
the amount necessary to make the amount, if any, on deposit in the Certificate
Account on the Final Distribution Date equal to the purchase price for the
related assets of the Trust computed as above provided together with a statement
as to the amount to be distributed on each Class of Certificates pursuant to the
next succeeding paragraph.

          Upon presentation and surrender of the Certificates, the Trustee shall
cause to be distributed to Certificateholders of each Class, in the order set
forth in Section 5.02 hereof, on the Final Distribution Date and in proportion
to their respective Percentage Interests, with respect to Certificateholders of
the same Class, an amount equal to (I) as to each Class of Certificates, the
Class Certificate Balance thereof plus (a) accrued interest thereon in the case
of an interest bearing Certificate and (b) the Class A-PO Deferred Amount with
respect to the Class A-PO Certificates, and (II) as to the Class A-R and A-LR
Certificates, the amounts, if any, which remain on deposit in the Upper-Tier
Certificate Account and the Certificate Account, respectively (other than the
amounts retained to meet claims) after application pursuant to clause (I) above.
An amount shall be distributed in respect of interest and principal to the
Uncertificated Lower-Tier Interests in the same amounts as distributed to their
Corresponding Upper-Tier Class or Classes.

          If all of the Certificateholders do not surrender their Certificates
for final payment and cancellation on or before the Final Distribution Date, the
Trustee shall on such date cause all funds in the Certificate Account not
distributed in final distribution to Certificateholders to continue to be held
by the Trustee in an Eligible Account for the benefit of such Certificateholders
and the Depositor (if it exercised its right to purchase the assets of the Trust
Estate) or the Trustee (in any other case) shall give a second written notice to
the remaining Certificateholders to surrender their Certificates for
cancellation and receive the final distribution with respect thereto. If within
one year after the second notice all the Certificates shall not have been
surrendered for cancellation, the Trustee may take appropriate steps, or may
appoint an agent to take appropriate steps, to contact the remaining
Certificateholders concerning surrender of their Certificates, and the cost
thereof shall be paid out of the funds on deposit in such Eligible Account.

          Section 10.02 Additional Termination Requirements.

          (a) If the Depositor exercises its purchase option as provided in
Section 10.01, the Trust shall be terminated in accordance with the following
additional requirements, unless the Trustee has received an Opinion of Counsel
to the effect that the failure of the Trust to comply with the requirements of
this Section 10.02 will not (i) result in the imposition of taxes on "prohibited
transactions" of the Trust as defined in Section 860F of the Code, or (ii) cause
the Trust Estate to fail to qualify as two separate REMICs at any time that any
Certificates are outstanding:

          (i)     within 90 days prior to the Final Distribution Date set forth
     in the notice given by the Depositor under Section 10.01, the Trustee shall
     sell all of the assets of the Trust Estate to the Depositor for cash; and

                                      -89-

<PAGE>

          (ii)    the notice given by the Depositor or the Trustee pursuant to
     Section 10.01 shall provide that such notice constitutes the adopting of a
     plan of complete liquidation of the Upper-Tier REMIC and the Lower-Tier
     REMIC as of the date of such notice (or, if earlier, the date on which such
     notice was mailed to Certificateholders). The Trustee shall also specify
     such date in the final tax return of the Upper-Tier REMIC and Lower-Tier
     REMIC.

          (b) By their acceptance of the Residual Certificates, the Holders
thereof hereby agree to take such other action in connection with such plan of
complete liquidation as may be reasonably requested by the Depositor.

                                   ARTICLE XI

                            MISCELLANEOUS PROVISIONS

          Section 11.01 Amendment. This Agreement may be amended from time to
time by the Depositor, the Servicer and the Trustee without the consent of any
of the Certificateholders, (i) to cure any ambiguity or mistake, (ii) to correct
or supplement any provisions herein or therein which may be inconsistent with
any other provisions of this Agreement, any amendment to this Agreement or the
related Prospectus Supplement, (iii) to modify, eliminate or add to any of its
provisions to such extent as shall be necessary to maintain the qualification of
the Upper-Tier REMIC and the Lower-Tier REMIC as REMICs at all times that any
Certificates are outstanding or to avoid or minimize the risk of the imposition
of any tax on the REMIC pursuant to the Code that would be a claim against the
Trust Estate, provided that (a) 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 (b) such action shall 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 (a) such change shall not, as evidenced by an Opinion of Counsel,
adversely affect in any material respect the interests of any Certificateholder
and (b) such change shall not adversely affect the then-current rating of the
Senior Certificates, the Class B-1 Certificates, the Class B-2 Certificates, the
Class B-3 Certificates, the Class B-4 Certificates or the Class B-5 Certificates
as evidenced by a letter from each Rating Agency rating such Certificates to
such effect, (v) to reduce the percentage of the Pool Principal Balance at which
the Depositor will have the option to purchase all the remaining Mortgage Loans
in accordance with Section 10.01, provided that such reduction is considered
necessary by the Depositor, as evidenced by an Officer's Certificate delivered
to the Trustee, to preserve the treatment of the transfer of the Mortgage Loans
to the Depositor by the Seller or to the Trust by the Depositor as sale for
accounting purposes, and (vi) to make any other provisions with respect to
matters or questions arising under this Agreement which shall not be materially
inconsistent with the provisions of this Agreement, provided that such action
shall not, as evidenced by an Opinion of Counsel, adversely affect in any
material respect the interests of any Certificateholder, provided that the
amendment shall not be deemed to adversely affect in any material respect the
interests of the Certificateholders and no Opinion of Counsel to that effect
shall be required if the Person requesting the amendment obtains a letter from
each Rating

                                      -90-

<PAGE>

Agency stating that the amendment would not result in the downgrading or
withdrawal of the respective ratings then assigned to the Certificates.

          This Agreement may also be amended from time to time by the Depositor,
the Servicer and the Trustee, with the consent of the Holders of Certificates of
each Class of Certificates which is affected by such amendment, evidencing, as
to each such Class of Certificates, Percentage Interests aggregating not less
than 66-2/3%, for the purpose of adding any provisions to or changing in any
manner or eliminating any of the provisions of this Agreement or of modifying in
any manner the rights of the Holders of such Certificates; provided, however,
that no such amendment shall (A) reduce in any manner the amount of, or delay
the timing of, collections of payments on Mortgage Loans or distributions which
are required to be made on any Certificate without the consent of the Holder of
such Certificate or (B) reduce the aforesaid percentage required to consent to
any such amendment, without the consent of the Holders of all Certificates then
Outstanding.

          Prior to the solicitation of consent of Certificateholders in
connection with any such amendment, the party seeking such amendment shall
furnish the Trustee with an Opinion of Counsel stating whether such amendment
would adversely affect the qualification of the Upper-Tier REMIC or the
Lower-Tier REMIC as REMICs and notice of the conclusion expressed in such
Opinion of Counsel shall be included with any such solicitation. An amendment
made with the consent of all Certificateholders and executed in accordance with
this Section 11.01 shall be permitted or authorized by this Agreement
notwithstanding that such Opinion of Counsel may conclude that such amendment
would adversely affect the qualification of the Upper-Tier REMIC or the
Lower-Tier REMIC as REMICs.

          Promptly after the execution of any such amendment or consent the
Trustee shall furnish written notification of the substance of or a copy of such
amendment to each Certificateholder and to each Rating Agency.

          It shall not be necessary for the consent of Certificateholders under
this Section 11.01 to approve the particular form of any proposed amendment, but
it shall be sufficient if such consent shall approve the substance thereof. The
manner of obtaining such consents and of evidencing the authorization of the
execution thereof by Certificateholders shall be subject to such reasonable
requirements as the Trustee may prescribe.

          Section 11.02 Recordation of Agreement. This Agreement is subject to
recordation in all appropriate public offices for real property records in all
the counties or other comparable jurisdictions in which any or all of the
properties subject to the Mortgages are situated, and in any other appropriate
public recording office or elsewhere, such recordation to be effected by the
Servicer and at its expense on direction by the Trustee, who will act at the
direction of Holders of Certificates evidencing not less than 50% of all Voting
Rights, but only upon direction of the Trustee accompanied by an Opinion of
Counsel to the effect that such recordation materially and beneficially affects
the interests of Certificateholders.

          For the purpose of facilitating the recordation of this Agreement as
herein provided and for other purposes, this Agreement may be executed
simultaneously in any number

                                      -91-

<PAGE>

of counterparts, each of which counterparts shall be deemed to be an original,
and such counterparts shall constitute but one and the same instrument.

          Section 11.03 Limitation on Rights of Certificateholders. The death or
incapacity of any Certificateholder shall not operate to terminate this
Agreement or the Trust, nor entitle such Certificateholder's legal
representatives or heirs to claim an accounting or to take any action or
commence any proceeding in any court for a partition or winding up of the Trust,
nor otherwise affect the rights, obligations and liabilities of the parties
hereto or any of them.

          No Certificateholder shall have any right to vote (except as provided
herein) or in any manner otherwise control the operation and management of the
Trust, or the obligations of the parties hereto, nor shall anything herein set
forth, or contained in the terms of the Certificates, be construed so as to
constitute the Certificateholders from time to time as partners or members of an
association; nor shall any Certificateholder be under any liability to any third
person by reason of any action taken by the parties to this Agreement pursuant
to any provision hereof.

          No Certificateholder shall have any right by virtue or by availing
itself of any provisions of this Agreement to institute any suit, action or
proceeding in equity or at law upon or under or with respect to this Agreement,
unless such Holder previously shall have given to the Trustee a written notice
of default and of the continuance thereof, as provided herein, and unless also
the Holders of Certificates evidencing Percentage Interests aggregating not less
than 25% of each Class of Certificates affected thereby shall have made written
request upon the Trustee to institute such action, suit or proceeding in its own
name as Trustee hereunder and shall have offered to the Trustee such reasonable
indemnity as it may require against the costs, expenses and liabilities to be
incurred therein or thereby, and the Trustee, for 60 days after its receipt of
such notice, request and offer of indemnity, shall have neglected or refused to
institute any such action, suit or proceeding; it being understood and intended,
and being expressly covenanted by each Certificateholder with every other
Certificateholder and the Trustee, that no one or more Holders of Certificates
shall have any right in any manner whatever by virtue or by availing itself or
themselves of any provisions of this Agreement to affect, disturb or prejudice
the rights of the Holders of any other of the Certificates, or to obtain or seek
to obtain priority over or preference to any other such Holder, or to enforce
any right under this Agreement, except in the manner herein provided and for the
equal, ratable and common benefit of all Certificateholders. For the protection
and enforcement of the provisions of this Section 11.03, each and every
Certificateholder and the Trustee shall be entitled to such relief as can be
given either at law or in equity.

          Section 11.04 Governing Law. THIS AGREEMENT SHALL BE CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT APPLICATION OF THE
CONFLICTS OF LAWS PROVISIONS THEREOF, AND THE OBLIGATIONS, RIGHTS AND REMEDIES
OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

shall be given by first class mail, postage prepaid, at the address of such
Holder as shown in the Certificate Register. Any notice so mailed within the
time prescribed in this Agreement shall be conclusively presumed to have been
duly given, whether or not the Certificateholder receives such notice.

          Section 11.06 Severability of Provisions. If any one or more of the
covenants, agreements, provisions or terms of this Agreement shall be for any
reason whatsoever held invalid, then such covenants, agreements, provisions or
terms shall be deemed severable from the remaining covenants, agreements,
provisions or terms of this Agreement and shall in no way affect the validity or
enforceability of the other provisions of this Agreement or of the Certificates
or the rights of the Holders thereof.

          Section 11.07 Certificates Nonassessable and Fully Paid. It is the
intention of the Trustee that Certificateholders shall not be personally liable
for obligations of the Trust Estate, that the beneficial ownership interests
represented by the Certificates shall be nonassessable for any losses or
expenses of the Trust Estate or for any reason whatsoever, and that Certificates
upon execution, countersignature and delivery thereof by the Trustee pursuant to
Section 6.01 are and shall be deemed fully paid.

          Section 11.08 Access to List of Certificateholders. The Certificate
Registrar will furnish or cause to be furnished to the Trustee, within 15 days
after the receipt of a request by the Trustee in writing, a list, in such form
as the Trustee may reasonably require, of the names and addresses of the
Certificateholders as of the most recent Record Date for payment of
distributions to Certificateholders.

          If three or more Certificateholders apply in writing to the Trustee,
and such application states that the applicants desire to communicate with other
Certificateholders with respect to their rights under this Agreement or under
the Certificates and is accompanied by a copy of the communication which such
applicants propose to transmit, then the Trustee shall, within five Business
Days after the receipt of such application, afford such applicants access during
normal business hours to the most recent list of Certificateholders held by the
Trustee. If such a list is as of a date more than 90 days prior to the date of
receipt of such applicants' request, the Trustee shall promptly request from the
Certificate Registrar a current list as provided above, and shall afford such
applicants access to such list promptly upon receipt.

                                      -93-

<PAGE>

          Every Certificateholder, by receiving and holding such list, agrees
with the Certificate Registrar and the Trustee that neither the Certificate
Registrar nor the Trustee shall be held accountable by reason of the disclosure
of any such information as to the names and addresses of the Certificateholders
hereunder, regardless of the source from which such information was derived.

          Section 11.09 Recharacterization. The parties to this Agreement intend
the conveyance by the Depositor to the Trustee of all of its right, title and
interest in and to the Mortgage Loans pursuant to this Agreement to constitute a
purchase and sale and not a loan. Notwithstanding the foregoing, to the extent
that such conveyance is held not to constitute a sale under applicable law, it
is intended that this Agreement shall constitute a security agreement under
applicable law and that the Depositor shall be deemed to have granted to the
Trustee a first priority security interest in all of the Depositor's right,
title and interest in and to the Mortgage Loans.

                                      -94-

set forth in the Pooling and Servicing Agreement. Accordingly, the Certificate
Balance of this Certificate at any time may be less than the Certificate Balance
as set forth herein. This Certificate does not evidence an obligation of, or an

referred to below or any of their respective affiliates. Neither this
Certificate nor the Mortgage Loans are guaranteed or insured by any governmental
agency or instrumentality.

          No transfer of a Certificate of this Class shall be made unless such
transfer is exempt from the registration requirements of the Securities Act of
1933, as amended (the "1933 Act"), and any applicable state securities laws or
is made in accordance with the 1933 Act and such laws. In the event of any such
transfer, (i) unless the transfer is made in reliance on Rule 144A under the
1933 Act, the Trustee or the Depositor may require a written Opinion of Counsel
(which may be in-house counsel) acceptable to and in form and substance
reasonably satisfactory to the Trustee and the Depositor that such transfer may
be made pursuant to an exemption, describing the applicable exemption and the
basis therefor, from the 1933 Act and such laws or is being made pursuant to the
1933 Act and such laws, which Opinion of Counsel shall not be an expense of the
Trustee or the Depositor and (ii) the Trustee shall require a certificate from
the Certificateholder desiring to effect such transfer substantially in the form
attached to the Pooling and Servicing Agreement as Exhibit G-1 and a certificate
from such Certificateholder's prospective transferee substantially in the form
attached to the Pooling and Servicing Agreement either as Exhibit G-2A or as
Exhibit G-2B, which certificates shall not be an expense of the Trustee or the
Depositor; provided that the foregoing requirements under clauses (i) and (ii)
shall not apply to a transfer of a Private Certificate between or among the
Depositor, the Seller, their affiliates or both. The Holder of a Private
Certificate desiring to effect such transfer shall, and does hereby agree to,
indemnify the Trustee and the Depositor against any liability that may result if
the transfer is not so exempt or is not made in accordance with such federal and
state laws.

          Reference is hereby made to the further provisions of this Certificate
set forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

          This Certificate shall not be entitled to any benefit under the
Pooling and Servicing Agreement or be valid for any purpose unless manually
countersigned by an authorized signatory of the Trustee.

                      [FORM OF REVERSE OF ALL CERTIFICATES]

                         BA RESIDENTIAL SECURITIES, INC.
                       Mortgage Pass-Through Certificates

          This Certificate is one of a duly authorized issue of Certificates
designated as BA Residential Securities, Inc. Mortgage Pass-Through
Certificates, of the Series specified on the face hereof (collectively, the
"Certificates"), and representing a beneficial ownership interest in the Trust
created by the Pooling and Servicing Agreement.

          The Certificateholder, by its acceptance of this Certificate, agrees
that it will look solely to the funds on deposit in the Certificate Account for
payment hereunder and that the Trustee is not liable to the Certificateholders
for any amount payable under this Certificate or the Pooling and Servicing
Agreement or, except as expressly provided in the Pooling and Servicing
Agreement, subject to any liability under the Pooling and Servicing Agreement.

          This Certificate does not purport to summarize the Pooling and
Servicing Agreement and reference is made to the Pooling and Servicing Agreement
for the interests, rights and limitations of rights, benefits, obligations and
duties evidenced thereby, and the rights, duties and immunities of the Trustee.

          Pursuant to the terms of the Pooling and Servicing Agreement, a
distribution will be made on the 25th day of each calendar month (or, if such
day is not a Business Day, the next Business Day) (each, a "Distribution Date"),
commencing on the first Distribution Date specified on the face hereof, to the
Person in whose name this Certificate is registered at the close of business on
the applicable Record Date in an amount required pursuant to the Pooling and
Servicing Agreement. The Record Date applicable to each Distribution Date is the
last Business Day of the month next preceding the month of such Distribution
Date.

          On each Distribution Date, the Trustee shall distribute out of the
Certificate Account to each Certificateholder of record on the related Record
Date (other than respecting the final distribution) (a) by check mailed to such
Certificateholder entitled to receive a distribution on such Distribution Date
at the address appearing in the Certificate Register, or (b) upon written
request by the Holder of a Regular Certificate (in the event such
Certificateholder owns of record 100% of a Class of Certificates or holds
Certificates of any Class having denominations aggregating $1,000,000 or more),
by wire transfer or by such other means of payment as such Certificateholder and
the Trustee shall agree upon, such Certificateholder's Percentage Interest in
the amount to which the related Class of Certificates is entitled in accordance
with the priorities set forth in Section 5.02 of the Pooling and Servicing
Agreement; provided, however, that in the case of the Class A-4 and Class A-5
Certificates, distributions of principal to which such Class is entitled will be
made to the Holders of such Class as described in Section 5.09 of the Pooling
and Servicing Agreement. The final distribution on each Certificate will be made
in like manner, but only upon presentation and

<PAGE>

surrender of such Certificate to the Trustee as contemplated by Section 10.01 of
the Pooling and Servicing Agreement.

          The Pooling and Servicing Agreement permits, with certain exceptions
therein provided, the amendment thereof and the modification of the rights and
obligations of the Trustee and the rights of the Certificateholders under the
Pooling and Servicing Agreement at any time by the Depositor, the Servicer and
the Trustee with the consent of the Holders of Certificates affected by such
amendment evidencing the requisite Percentage Interest, as provided in the
Pooling and Servicing Agreement. Any such consent by the Holder of this
Certificate shall be conclusive and binding on such Holder and upon all future
Holders of this Certificate and of any Certificate issued upon the transfer
hereof or in exchange therefor or in lieu hereof whether or not notation of such
consent is made upon this Certificate. The Pooling and Servicing Agreement also
permits the amendment thereof, in certain limited circumstances, without the
consent of the Holders of any of the Certificates.

          As provided in the Pooling and Servicing Agreement and subject to
certain limitations therein set forth, the transfer of this Certificate is
registrable in the Certificate Register of the Trustee upon surrender of this
Certificate for registration of transfer at the Corporate Trust Office
accompanied by a written instrument of transfer in form satisfactory to the
Trustee and the Certificate Registrar duly executed by the Holder hereof or such
Holder's attorney duly authorized in writing, and thereupon one or more new
Certificates of the same Class in authorized denominations and evidencing the
same aggregate Percentage Interest in the Trust will be issued to the designated
transferee or transferees.

          The Certificates are issuable only as registered Certificates without
coupons in denominations specified in the Pooling and Servicing Agreement. As
provided in the Pooling and Servicing Agreement and subject to certain
limitations therein set forth, Certificates are exchangeable for new
Certificates of the same Class in authorized denominations and evidencing the
same aggregate Percentage Interest, as requested by the Holder surrendering the
same.

          No service charge will be made for any such registration of transfer
or exchange, but the Trustee may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith.

          The Depositor, the Servicer, the Certificate Registrar and the Trustee
and any agent of the Depositor, the Servicer, the Certificate Registrar or the
Trustee may treat the Person in whose name this Certificate is registered as the
owner hereof for all purposes, and none of the Depositor, the Servicer, the
Certificate Registrar, the Trustee or any such agent shall be affected by any
notice to the contrary.

          On any Distribution Date on which the aggregate Stated Principal
Balance is less than 1% of the aggregate aggregate Cut-Off Date Principal
Balance, the Depositor will have the option to repurchase, in whole, from the
Trust all remaining Mortgage Loans and all property acquired in respect of such
Mortgage Loans at a purchase price determined as provided in the Pooling and
Servicing Agreement. The 10% may be reduced by an amendment to the Pooling and
Servicing Agreement without Certificateholder consent under certain conditions
set forth in the Pooling

                                       C-2

<PAGE>

and Servicing Agreement. In the event that no such optional repurchase occurs,
the obligations and responsibilities created by the Pooling and Servicing
Agreement will terminate upon the later of the maturity or other liquidation (or
any advance with respect thereto) of the last Mortgage Loan remaining in the
Trust or the disposition of all property in respect thereof and the distribution
to Certificateholders of all amounts required to be distributed pursuant to the
Pooling and Servicing Agreement. In no event shall the Trust created by the
Pooling and Servicing Agreement continue beyond the expiration of 21 years from
the death of the last survivor of the descendants of Joseph P. Kennedy, the late
ambassador of the United States to the Court of St. James, living on the date
thereof.

          Any term used herein that is defined in the Pooling and Servicing
Agreement shall have the meaning assigned in the Pooling and Servicing
Agreement, and nothing herein shall be deemed inconsistent with that meaning.

Ladies and Gentlemen:

          This letter is delivered to you in connection with the transfer by
[______________] (the "Transferor") to [______________] (the "Transferee") of
the captioned Certificates (the "Transferred Certificates"), pursuant to Section
6.02 of the Pooling and Servicing Agreement (the "Pooling and Servicing

the respective meanings set forth in the Pooling and Servicing Agreement. The
Transferor hereby certifies, represents and warrants to you, as Trustee, that:

               1.   The Transferor is the lawful owner of the Transferred
          Certificates with the full right to transfer such Certificates free
          from any and all claims and encumbrances whatsoever.

               2.   Neither the Transferor nor anyone acting on its behalf has
          (a) offered, transferred, pledged, sold or otherwise disposed of any
          Transferred Certificate, any interest in a Transferred Certificate or
          any other similar security to any person in any manner, (b) solicited
          any offer to buy or accept a transfer, pledge or other disposition of
          any Transferred Certificate, any interest in a Transferred Certificate
          or any other similar security from any person in any manner, (c)
          otherwise approached or negotiated with respect to any Transferred
          Certificate, any interest in a Transferred Certificate or any other
          similar security with any person in any manner, (d) made any general
          solicitation with respect to any Transferred Certificate, any interest
          in a Transferred Certificate or any other similar security by means of

          Transferred Certificate or any other similar security, which (in the
          case of any of the acts described in clauses (a) through (e) hereof)
          would constitute a distribution of the Transferred Certificates under
          the Securities Act of 1933, as amended (the "1933 Act"), would render
          the disposition of the Transferred Certificates a violation of Section

<PAGE>

of those securities has been published, in which case the securities were valued
at market. Further, in determining such aggregate amount, the Transferee may
have included securities owned by subsidiaries of the Transferee, but only if
such subsidiaries are consolidated with the Transferee in its financial
statements prepared in accordance with generally accepted accounting principles
and if the investments of such subsidiaries are managed under the Transferee's

amended.

          5.   The Transferee is familiar with Rule 144A and understands that
the Transferor and other parties related to the Transferred Certificates are
relying and will continue to rely on the statements made herein because one or
more sales to the Transferee may be in reliance on Rule 144A.

                 ____     ____        Will the Transferee be purchasing the
                 Yes      No          Transferred Certificates only for the
                                      Transferee's own account?

          6.   If the answer to the foregoing question is "no," then in each
case where the Transferee is purchasing for an account other than its own, such
account belongs to a third party that is itself a "qualified institutional
buyer" within the meaning of Rule 144A, and the "qualified institutional buyer"
status of such third party has been established by the Transferee through one or
more of the appropriate methods contemplated by Rule 144A.

          7.   The Transferee will notify each of the parties to which this
certification is made of any changes in the information and conclusions herein.
Until such notice is given, the Transferee's purchase of the Transferred
Certificates will constitute a reaffirmation of this certification as of the
date of such purchase. In addition, if the Transferee is a bank or savings and
loan as provided above, the Transferee agrees that it will furnish to such
parties any updated annual financial statements that become available on or
before the date of such purchase, promptly after they become available.

            QUALIFIED INSTITUTIONAL BUYER STATUS UNDER SEC RULE 144A

           [For Transferees That Are Registered Investment Companies]

          The undersigned hereby certifies as follows to [_________________]
(the "Transferor") and ____________________, as Trustee, with respect to the
mortgage pass-through certificates (the "Transferred Certificates") described in
the Transferee certificate to which this certification relates and to which this
certification is an Annex:

          1.   As indicated below, the undersigned is the chief financial
officer, a person fulfilling an equivalent function, or other executive officer
of the entity purchasing the Transferred Certificates (the "Transferee") or, if
the Transferee is a "qualified institutional buyer" as that term is defined in
Rule 144A ("Rule 144A") under the Securities Act of 1933, as amended, because
the Transferee is part of a Family of Investment Companies (as defined below),
is an executive officer of the investment adviser (the "Adviser").

          2.   The Transferee is a "qualified institutional buyer" as defined in
Rule 144A because (i) the Transferee is an investment company registered under
the Investment Company Act of 1940, and (ii) as marked below, the Transferee
alone owned and/or invested on a discretionary basis, or the Transferee's Family
of Investment Companies owned, at least $100,000,000 in securities (other than
the excluded securities referred to below) as of the end of the Transferee's
most recent fiscal year. For purposes of determining the amount of securities
owned by the Transferee or the Transferee's Family of Investment Companies, the
cost of such securities was used, unless the Transferee or any member of the
Transferee's Family of Investment Companies, as the case may be, reports its
securities holdings in its financial statements on the basis of their market
value, and no current information with respect to the cost of those securities
has been published, in which case the securities of such entity were valued at
market.

          .    The Transferee owned and/or invested on a discretionary basis
               $____________________ in securities (other than the excluded
               securities referred to below) as of the end of the Transferee's
               most recent fiscal year (such amount being calculated in
               accordance with Rule 144A).

          .    The Transferee is part of a Family of Investment Companies which
               owned in the aggregate $__________________ in securities (other
               than the excluded securities referred to below) as of the end of
               the Transferee's most recent fiscal year (such amount being
               calculated in accordance with Rule 144A).

          3.   The term "Family of Investment Companies" as used herein means
two or more registered investment companies (or series thereof) that have the
same investment adviser or

                                     G-2A-7

<PAGE>

investment advisers that are affiliated (by virtue of being majority owned
subsidiaries of the same parent or because one investment adviser is a majority
owned subsidiary of the other).

          4.   The term "securities" as used herein does not include (i)
securities of issuers that are affiliated with the Transferee or are part of the
Transferee's Family of Investment Companies, (ii) bank deposit notes and
certificates of deposit, (iii) loan participations, (iv) repurchase agreements,
(v) securities owned but subject to a repurchase agreement and (vi) currency,
interest rate and commodity swaps. For purposes of determining the aggregate
amount of securities owned and/or invested on a discretionary basis by the
Transferee, or owned by the Transferee's Family of Investment Companies, the
securities referred to in this paragraph were excluded.

          5.   The Transferee is familiar with Rule 144A and understands that
the Transferor and other parties related to the Transferred Certificates are
relying and will continue to rely on the statements made herein because one or
more sales to the Transferee will be in reliance on Rule 144A.

                 ____     ____        Will the Transferee be purchasing the
                 Yes      No          Transferred Certificates only for the
                                      Transferee's own account?

          6.   If the answer to the foregoing question is "no," then in each
case where the Transferee is purchasing for an account other than its own, such
account belongs to a third party that is itself a "qualified institutional
buyer" within the meaning of Rule 144A, and the "qualified institutional buyer"
status of such third party has been established by the Transferee through one or
more of the appropriate methods contemplated by Rule 144A.

          7.   The undersigned will notify the parties to which this
certification is made of any changes in the information and conclusions herein.
Until such notice, the Transferee's purchase of the Transferred Certificates
will constitute a reaffirmation of this certification by the undersigned as of
the date of such purchase.

Ladies and Gentlemen:

          This letter is delivered to you in connection with the transfer by
[_______________________] (the "Transferor") to [_______________________________
__] (the "Transferee") of the captioned Certificates (the "Transferred
Certificates"), pursuant to Section 6.02 of the Pooling and Servicing Agreement
(the "Pooling and Servicing Agreement"), dated , 200 , among BA Residential
Securities, Inc., as Depositor, Bank of America, N.A., as Servicer, and
____________________, as Trustee. All capitalized terms used herein and not
otherwise defined shall have the respective meanings set forth in the Pooling
and Servicing Agreement. The Transferor hereby certifies, represents and
warrants to you, as Trustee, that:

          1.   Transferee is acquiring the Transferred Certificates for its own
account for investment and not with a view to or for sale or transfer in
connection with any distribution thereof, in whole or in part, in any manner
which would violate the Securities Act of 1933, as amended (the "1933 Act"), or
any applicable state securities laws.

          2.   Transferee understands that (a) the Transferred Certificates have
not been and will not be registered under the 1933 Act or registered or
qualified under any applicable state securities laws, (b) neither the Depositor
nor the Trustee is obligated so to register or qualify the Transferred
Certificates and (c) neither the Transferred Certificates nor any security
issued in exchange therefor or in lieu thereof may be resold or transferred
unless such resale or transfer is exempt from the registration requirements of
the 1933 Act and any applicable state securities laws or is made in accordance
with the 1933 Act and laws, in which case (i) unless the transfer is made in
reliance on Rule 144A under the 1933 Act, the Trustee or the Depositor may
require a written Opinion of Counsel (which may be in-house counsel) acceptable
to and in form and substance reasonably satisfactory to the Trustee and the
Depositor that such transfer may be made pursuant to an exemption, describing
the applicable exemption and the basis therefor, from the 1933 Act and such laws
or is being made pursuant to the 1933 Act and such laws, which Opinion of
Counsel shall not be an expense of the Trustee or the Depositor and (ii) the
Trustee shall require a

          AN INTEREST IN SUCH GENERAL ACCOUNT ARE PLANS TO WHICH PTE 95-60
          APPLIES, OR (II) AN OPINION OF COUNSEL, IN FORM AND SUBSTANCE

          UNDERTAKEN IN THE POOLING AND SERVICING AGREEMENT. EACH PERSON WHO
          ACQUIRES THIS CERTIFICATE OR ANY INTEREST THEREIN SHALL BE DEEMED TO

          AGREEMENT PROVIDES 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.

          4.   Neither the Transferee nor anyone acting on its behalf has (a)

Transferred Certificate, any interest in a Transferred Certificate or any other
similar security with any person in any manner, (d) made any general
solicitation by means of general advertising or in any other manner, or (e)
taken any other action, that (in the case of any of the acts described in
clauses (a) through (e) above) would constitute a distribution of the
Transferred Certificates under the 1933 Act, would render the disposition of the
Transferred Certificates a violation of Section 5 of the 1933 Act or any state
securities law or would require registration or qualification of the Transferred
Certificates pursuant thereto. The Transferee will not act, nor has it
authorized nor will it authorize any person to act, in any manner set forth in
the foregoing sentence with respect to the Transferred Certificates, any
interest in the Transferred Certificates or any other similar security.

          5.   The Transferee has been furnished with all information regarding

Ladies and Gentlemen:

          This letter is delivered to you in connection with the transfer by
[_______________________] (the "Transferor") to [______________________________]
(the "Transferee") of the captioned Certificates (the "Transferred
Certificates"), pursuant to Section 6.02 of the Pooling and Servicing Agreement
(the "Pooling and Servicing Agreement"), dated     , 200 , among BA Residential
Securities, Inc., as Depositor, Bank of America, N.A., as Servicer, and
____________________, as Trustee. All capitalized terms used herein and not
otherwise defined shall have the respective meanings set forth in the Pooling
and Servicing Agreement.

          The Transferee hereby certifies, represents and warrants to you, as
Trustee, either that:

          (a)  it is not, and is not acting on behalf of, an employee benefit
plan or arrangement, including an individual retirement account, subject to the
Employee Retirement Income Security Act of 1974, as amended ("ERISA"), the
Internal Revenue Code of 1986, as amended (the "Code"), or any federal, state or
local law ("Similar Law") which is similar to ERISA or the Code (collectively, a
"Plan"), and it is not using the assets of any such Plan to effect the purchase
of the Transferred Certificates; or

          (b)  it is an insurance company and the source of funds used to
purchase the Transferred Certificates is an "insurance company general account"
(as defined in Section V(e) of Prohibited Transaction Class Exemption 95-60
("PTE 95-60"), 60 Fed. Reg. 35925 (July 12, 1995)), there is no Plan with
respect to which the amount of such general account's reserves and liabilities
for the contract(s) held by or on behalf of such Plan and all other Plans
maintained by the same employer (or affiliate thereof as defined in Section
V(a)(1) of PTE 95-60) or by the same employee organization exceeds 10% of the
total of all reserves and liabilities of such general account (as such amounts
are determined under Section I(a) of PTE 95-60) at the date of acquisition and
all Plans that have an interest in such general account are Plans to which PTE
95-60 applies.

                  RESIDUAL CERTIFICATE PURSUANT TO SECTION 6.02

                       Mortgage Pass-Through Certificates,

STATE OF              )
                      )  ss:
COUNTY OF             )

          The undersigned, being first duly sworn, deposes and says as follows:

          1.   The undersigned is an officer of _______________________________,
the proposed transferee (the "Transferee") of the Class A-R or Class A-LR
Certificate (the "Certificate") issued pursuant to the Pooling and Servicing
Agreement, dated     , 200 , (the "Agreement"), relating to the above-referenced
Series, by and among BA Residential Securities, Inc., as depositor (the
"Depositor"), Bank of America, N.A., as servicer, and ____________________, as
trustee. Capitalized terms used but not defined herein shall have the meanings
ascribed to such terms in the Agreement. The Transferee has authorized the
undersigned to make this affidavit on behalf of the Transferee.

          2.   The Transferee is, as of the date hereof, and will be, as of the
date of the transfer, a Permitted Transferee. The Transferee is acquiring the
Certificate either (i) for its own account or (ii) as nominee, trustee or agent
for another Person who is a Permitted Transferee and has attached hereto an
affidavit from such Person in substantially the same form as this affidavit. The
Transferee has no knowledge that any such affidavit is false.

          3.   The Transferee has been advised of, and understands that (i) a
tax will be imposed on Transfers of the Certificate to Persons that are not
Permitted Transferees; (ii) such tax will be imposed on the transferor, or, if
such transfer is through an agent (which includes a broker, nominee or
middleman) for a Person that is not a Permitted Transferee, on the agent; and
(iii) the Person otherwise liable for the tax shall be relieved of liability for
the tax if the subsequent Transferee furnished to such Person an affidavit that
such subsequent Transferee is a Permitted Transferee and, at the time of
transfer, such Person does not have actual knowledge that the affidavit is
false.

          4.   The Transferee has been advised of, and understands that a tax
will be imposed on a "pass-through entity" holding the Certificate if at any
time during the taxable year of the pass-through entity a Person that is not a
Permitted Transferee is the record Holder of an interest in such entity. The
Transferee understands that, other than in the case of an "electing large
partnership" under Section 775 of the Code, such tax will not be imposed for any
period with respect to which the record Holder furnishes to the pass-through
entity an affidavit that such

<PAGE>

record Holder is a Permitted Transferee and the pass-through entity does not
have actual knowledge that such affidavit is false. (For this purpose, a
"pass-through entity" includes a regulated investment company, a real estate
investment trust or common trust fund, a partnership, trust or estate, and
certain cooperatives and, except as may be provided in Treasury Regulations,
persons holding interests in pass-through entities as a nominee for another
Person.)

          5.   The Transferee has reviewed the provisions of Section 6.02 of the
Agreement and understands the legal consequences of the acquisition of the
Certificate including, without limitation, the restrictions on subsequent
Transfers and the provisions regarding voiding the transfer and mandatory sales.
The Transferee expressly agrees to be bound by and to abide by the provisions of
Section 6.02 of the Agreement and the restrictions noted on the face of the
Certificate. The Transferee understands and agrees that any breach of any of the
representations included herein shall render the transfer to the Transferee
contemplated hereby null and void.

          6.   The Transferee agrees to require a transfer affidavit in the form
of this Affidavit from any Person to whom the Transferee attempts to transfer
the Certificate, and in connection with any transfer by a Person for whom the
Transferee is acting as nominee, trustee or agent, and the Transferee will not
transfer the Certificate or cause the Certificate to be transferred to any
Person that the Transferee knows is not a Permitted Transferee.

          7.   The Transferee historically has paid its debts as they have
become due.

          8.   The Transferee does not have the intention to impede the
assessment or collection of any tax legally required to be paid with respect to
the Certificate.

          9.   The Transferee's taxpayer identification number is ______________
__________.

          10.  The Transferee is a U.S. Person as defined in Code Section
7701(a)(30).

          11.  The Transferee is aware that the Certificate may be a
"noneconomic residual interest" within the meaning of proposed Treasury
Regulations promulgated pursuant to the Code and that the transferor of a
noneconomic residual interest will remain liable for any taxes due with respect
to the income on such residual interest, unless no significant purpose of the
transfer was to impede the assessment or collection of tax. The Transferee
understands that it may incur tax liabilities with respect to the Certificate in
excess of cash flows generated thereby, and agrees to pay taxes associated with
holding the Certificate as such taxes become due.

                                       I-2

<PAGE>

          12.  The Transferee is not an employee benefit plan or arrangement,
including an individual retirement account, subject to ERISA, the Code or any
federal, state or local law which is similar to ERISA or the Code, and the
Transferee is not acting on behalf of such a plan or arrangement.

          below the most recent market valuation of that property obtained by
          the Servicer (or if no such valuation has been obtained, the appraisal
          used in connection with the originating of the related Mortgage Loan),
          the Servicer shall notify the Loss Mitigation Advisor of such offer
          and shall provide a justification for accepting such offer, if that is
          the Servicer's recommendation.

               (vi) Within five (5) business days of receipt by the Servicer

provided that the Servicer shall only be required to provide information that is
readily accessible to their servicing personnel.

          (c) In addition to the foregoing, the Servicer shall provide to the
Loss Mitigation Advisor such information as the Loss Mitigation Advisor may
reasonably request concerning each Mortgage Loan that is at least sixty days
delinquent and each Mortgage Loan which has become real estate owned, provided
that the Servicer shall only be required to provide information that is readily
accessible to its servicing personnel.

          (d) With respect to all Mortgage Loans which are serviced at any time
by the Servicer through a subservicer, the Servicer shall be entitled to rely
for all purposes hereunder, including for purposes of fulfilling its reporting
obligations under this Section 2.01, on the accuracy and completeness of any
information provided to it by the applicable subservicer.

               Section 2.02. Loss Mitigation Advisor's Recommendations With
Respect to Defaulted Loans.

          (a) All parties to this Agreement acknowledge that the Loss Mitigation
Advisor's advice is made in the form of recommendations, and that the Loss
Mitigation Advisor does not have the right to direct the Servicer in performing
its duties under the Pooling and Servicing Agreement. The Servicer may, after
review and analysis of the Loss Mitigation Advisor's recommendation, accept or
reject it, in the Servicer's sole discretion, subject to the standards of the
Servicer to protect the interest of the Certificateholders set forth in the
Pooling and Servicing Agreement.

          (b) Within two (2) business days of receipt of a notice of a
foreclosure delay, the Loss Mitigation Advisor shall provide the Servicer with a
recommendation regarding the delay, provided, however, that if additional
information is required on which to base a recommendation, the Loss Mitigation
Advisor shall notify the Servicer of the additional information needed within
the allotted time, and the Servicer shall promptly provide such information and
the Loss Mitigation Advisor shall then submit to the Servicer its
recommendation. The Loss Mitigation Advisor may recommend that additional
procedures be undertaken to further analyze the property, the borrower, or
issues related to the default or foreclosure. Such additional procedures may
include asset searches, property valuations, legal analysis or other procedures
that are

                                       K-4

<PAGE>

warranted by the circumstances of the property, borrower or foreclosure. The
Loss Mitigation Advisor may recommend such other actions as are warranted by the
circumstances of the property, borrower or foreclosure.

          (c) Within two (2) business days of receipt of a notice of a proposed
Short Payoff, the Loss Mitigation Advisor shall provide the Servicer with a
recommendation regarding the proposed Short Payoff, provided, however, that if
additional information is required on which to base a recommendation, the Loss
Mitigation Advisor shall notify the Servicer of the additional information
needed within two business days, and the Servicer shall promptly provide such
information and the Loss Mitigation Advisor shall then submit to the Servicer
its recommendation. The Loss Mitigation Advisor's recommendation may take the
form of concurring with the proposed Short Payoff, recommending against such
Short Payoff, with a justification provided, or proposing a counteroffer.

          (d) Within two (2) business days of receipt of a notice of an REO sale
at an amount that is more than 15% below the recent market valuation of that
property, the Loss Mitigation Advisor shall provide the Servicer with its
recommendation. The Loss Mitigation Advisor's recommendation may take the form
of concurring with the proposed below-market sale, recommending against such
below-market sale, or proposing a counteroffer.

               Section 2.03. Termination.

          (a) With respect to all Mortgage Loans included in a trust fund, the
Servicer's obligations under Section 2.01 and Section 2.02 shall terminate at
such time as the Certificate Principal Balances of the related Class B
Certificates have been reduced to zero.

          (b) The Loss Mitigation Advisor's responsibilities under this
Agreement shall terminate upon the termination of the fee agreement between the
Purchaser or its successor and the Loss Mitigation Advisor. The Loss Mitigation
Advisor shall promptly notify the Servicer of the date of termination of such
fee agreement, but in no event later than 5:00 P.M., EST, on the effective date
thereof.

          (c) Neither the Servicer nor any of its directors, officers, employees
or agents shall be under any liability for any action taken or for refraining
from the taking of any action in good faith pursuant to this Agreement, or for
errors in judgment; provided, however, that this provision shall not protect the
Servicer or any such Person against any liability which would otherwise be
imposed by reason of willful misfeasance, bad faith or gross negligence in the
performance of duties or by reason of reckless disregard of obligations and
duties hereunder. The Servicer and the Loss Mitigation Advisor and any director,
officer, employee or agent thereof may rely in good faith on any document of any
kind prima facie properly executed and submitted by any Person respecting any
matters arising hereunder. Neither the Loss Mitigation Advisor, its directors,
officers, employees or agents shall be under any liability for any actions taken
by the Servicer based upon the recommendation pursuant to this Agreement,
provided they are made in good faith.
