         This Pooling and Servicing Agreement, dated and effective as of April
1, 2001 (this "Agreement"), is executed by and among ABN AMRO Mortgage
Corporation, as depositor (the "Depositor"), Washington Mutual Mortgage
Securities Corp., as servicer (the "Servicer"), and State Street Bank and Trust
Company, as trustee (the "Trustee"). Capitalized terms used in this Agreement
and not otherwise defined have the meanings ascribed to such terms in Article I
hereof.

                              PRELIMINARY STATEMENT

         The Depositor at the Closing Date is the owner of the Loans and the
other property being conveyed by it to the Trustee for inclusion in the Trust
Fund. On the Closing Date, the Depositor will acquire the Certificates from the
Trust Fund as consideration for its transfer to the Trust Fund of the Loans and
certain other assets and will be the owner of the Certificates. The Depositor
has duly authorized the execution and delivery of this Agreement to provide for
the conveyance to the Trustee of the Loans and the issuance to the Depositor of
the Certificates representing in the aggregate the entire beneficial ownership
of the Trust Fund. All covenants and agreements made by the Depositor, the
Servicer and the Trustee herein with respect to the Loans and the other property
constituting the Trust Fund are for the benefit of the Holders from time to time
of the Certificates. The Depositor and the Servicer are entering into this
Agreement, and the Trustee is accepting the trust created hereby, for good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged.

         The Certificates issued hereunder, other than the Class B-3, Class B-4
and Class B-5 Certificates have been offered for sale pursuant to a Prospectus,
dated October 12, 1999, and a Prospectus Supplement, dated April 27, 2001 of the
Depositor (together, the "Prospectus"). The Class B-3, Class B-4 and Class B-5
Certificates have been offered for sale pursuant to a Private Placement
Memorandum dated April 27, 2001. The Trust Fund created hereunder is intended to
be the "Trust" as described in the Prospectus and the Private Placement
Memorandum and the Certificates are intended to be the "Certificates" described
therein.

         As provided herein, the Trustee will elect to treat the segregated pool
of assets consisting of the Loans and other related assets in the Trust Fund
subject to this Agreement as a REMIC for federal income tax purposes, and such
segregated pool of assets will be designated as "REMIC I." Component R-1 of the
Class R Certificates will represent the sole class of "residual interests" in
REMIC I for purposes of the REMIC Provisions under federal income tax law.

         As provided herein, the Trustee will elect to treat the segregated pool
of assets consisting of the REMIC I Regular Interests as a REMIC for federal
income tax purposes, and such segregated pool of assets will be designated as
"REMIC II." Component R-2 of the Class R Certificates will represent the sole
class of "residual interests" in REMIC II for purposes of the REMIC Provisions
under federal income tax law. The following table irrevocably sets forth the
designations, the Remittance Rate and initial Class Principal Balance for each
Class of Certificates which, together with the Class R-2 Component, constitute
the entire beneficial interests in REMIC II. Determined solely for purposes of
satisfying Treasury regulation section 1.860G-1(a)(4)(iii), the "latest possible
maturity date" for each of the REMIC I Regular Interests and for each Class of
Certificates shall be the first Distribution Date that is at least two years
after the end of the remaining amortization schedule of the Loan in the Mortgage
Pool that has,

                                       1

irrespective of its scheduled maturity. The following table sets forth the

<PAGE>

         office, with evidence of recording thereon, or certified by a
         title insurance company or escrow company to be a true copy thereof;
         provided, that if such original assignment or power of attorney cannot
         be delivered with evidence of recording thereon on or prior to the
         Closing Date because of a delay caused by the public recording office
         where such original assignment has been delivered for recordation or
         because such original Assignment has been lost, the Depositor shall
         deliver or cause to be delivered to the Trustee a true and correct copy
         of such Assignment, together with (a) in the case of a delay caused by
         the public recording office, an Officer's Certificate signed by a
         Responsible Officer of the Seller or by the originator of the related
         Loan stating that such original assignment has been dispatched to the
         appropriate public recording official for recordation or (b) in the
         case of an original assignment that has been lost, a certificate by the
         appropriate county recording office where such assignment is recorded
         or from a title insurance company or escrow company indicating that
         such original was lost and the copy of the original assignment is a
         true and correct copy;

               (v) The original mortgagee policy of title insurance (including,
         if applicable, the endorsement relating to the negative amortization of
         the Loans) or in the event such original title policy is unavailable,
         any one of an original title binder, an original preliminary title
         report or an original title commitment or a copy thereof certified by
         the title company with the original policy of title insurance to follow
         within 180 days of the Closing Date;

               (vi) The mortgage insurance certificate;

               (vii) Hazard insurance certificates and copies of the hazard
         insurance policy and, if applicable, flood insurance policy; and

               (viii) Any and all other documents, opinions and certificates
         executed and/or delivered by the related Mortgagor and/or its counsel
         in connection with the origination of such Mortgage Loan, which may
         include truth-in-lending statements and other legal statements, an
         appraisal and a survey.

The documents and instruments set forth in clauses (i) - (viii) above shall be
called, collectively, the "Mortgage File".

         If the Depositor cannot deliver the original Mortgage with evidence of
recording thereon concurrently with the execution and delivery of this Agreement
because of a delay caused by the public recording office where such original
Mortgage has been delivered for recordation, the Depositor shall deliver to the
Trustee an Officer's Certificate, with a photocopy of such Mortgage attached
thereto, stating that such original Mortgage has been delivered to the
appropriate public recording official for recordation. The Depositor shall
promptly deliver to the Trustee such original Mortgage with evidence of
recording indicated thereon upon receipt thereof from the public recording
official.

         The Depositor shall, at its own expense, promptly record or cause to be
recorded in the appropriate public real property or other records each
Assignment referred to in Section 2.1(ii), unless the Depositor delivers to the
Trustee an Independent opinion of counsel admitted to

                                       34

<PAGE>

practice law in the state in which such Mortgaged Property is located to the
effect that such recordation is not necessary to secure the interest in the
related Mortgaged Properties against any other transferee or creditor of the
Depositor, in which case such Assignments shall be delivered to the Trustee for
the benefit of the Certificateholders in recordable form. If the Depositor
cannot deliver the original Assignment concurrently with the execution and
delivery of this Agreement solely because it is in the process of being prepared
and recorded or because of a delay caused by the public recording office where
such original Assignment has been delivered for recordation, the Depositor shall
deliver a blanket Officer's Certificate covering all such Assignments stating
that such original Assignment is in the process of being prepared and recorded
or it has been delivered to the appropriate public recording official for
recordation. Any such original recorded Assignment shall be delivered to the
Trustee within 180 days following the execution of this Agreement.

         If the Depositor cannot deliver the original title insurance policy
concurrently with the execution and delivery of this Agreement, the Depositor
shall promptly deliver each such original title insurance policy as soon as such
policy becomes available but in no event later than 120 days following the
execution of this Agreement.

         All rights arising out of Loans including, without limitation, all
funds received on or in connection with a Loan shall be held by the Depositor in
trust for the benefit of the Certificateholders. The Depositor shall maintain a
complete set of books and records for each Loan which shall be clearly marked to
reflect the ownership of each Loan by the Certificateholders.

         It is the express intent of this Agreement that the conveyance of the
Loans by the Depositor to the Trustee as provided in this Section 2.1 be, and be
construed as, a sale of the Loans by the Depositor to the Trustee and that the
sale of the Certificates to the Certificateholders, if they are sold, be, and be
construed as, a sale of a 100% interest in the Loans and the Trust Fund to such
Certificateholders. It is, further, not the intention of this Agreement that
such conveyance be deemed a pledge of the Loans by the Depositor to the Trustee
to secure a debt or other obligation of the Depositor. However, in the event
that, notwithstanding the intent of this Agreement, the Loans are held to be
property of the Depositor, or if for any other reason this Agreement is held or
deemed to create a security interest in the Loans, then (a) this Agreement shall
also be deemed to be a security agreement within the meaning of Articles 8 and 9
of the New York Uniform Commercial Code; (b) the conveyance provided for in this
Section 2.1 shall be deemed to be a grant by the Depositor to the Trustee for
the benefit of the Certificateholders of a security interest in all of the
Depositor's right, title and interest in and to the Loans and all amounts
payable to the holders of the Loans in accordance with the terms thereof and all
proceeds of the conversion, voluntary or involuntary, of the foregoing into
cash, instruments, securities or other property, including without limitation
all amounts, other than investment earnings, from time to time held or invested
in the Certificate Account, whether in the form of cash, instruments, securities
or other property; (c) the possession by the Trustee or any Custodian of
Mortgage Notes and such other items of property as constitute instruments,
money, negotiable documents or chattel paper shall be deemed to be "in
possession by the secured party" for purposes of perfecting the security
interest pursuant to Section 9-305 of the New York Uniform Commercial Code; and
(d) notifications to persons holding such property, and acknowledgments,
receipts or confirmations from persons holding such property, shall be

                                       35

<PAGE>

deemed notifications to, or acknowledgments, receipts or confirmations from,
financial intermediaries, bailees or agents (as applicable) of the Trustee for
the benefit of the Certificateholders for the purpose of perfecting such
security interest under applicable law (except that nothing in this clause (d)
shall cause any person to be deemed to be an agent of the Trustee for any
purpose other than for perfection of such security interest unless, and then
only to the extent, expressly appointed and authorized by the Trustee in
writing). The Depositor and the Trustee, upon directions from the Depositor,
shall, to the extent consistent with this Agreement, take such actions as may be
necessary to ensure that, if this Agreement were deemed to create a perfected
security interest in Loans, such security interest would be deemed to be a
perfected security interest of first priority under applicable law and will be
maintained as such throughout the term of this Agreement.

         The Trustee is authorized to appoint any bank or trust company approved
by the Depositor as Custodian of the documents or instruments referred to under
(i) through (viii) above, and to enter into a Custodial Agreement for such
purpose and any documents delivered thereunder shall be delivered to the
Custodian and any Officer's Certificates delivered with respect thereto shall be
delivered to the Trustee and the Custodian.

         Section 2.2 Acceptance by Trustee. The Trustee acknowledges, subject to
the provisions of Section 2.1 and to any document exceptions reported pursuant
to the Trustee's reviews as described below, receipt of the Mortgage Notes (or
lost note affidavits and indemnities), the Mortgages, the assignments of the
Mortgages and the Officer's Certificates referred to in Section 2.1 above, and
declares that it holds and will hold such documents and the other documents
constituting a part of the Mortgage Files delivered to it as Trustee in trust,
upon the trusts herein set forth, for the use and benefit of all present and
future Certificateholders. The Trustee acknowledges that, as of the date of the
execution of this Agreement, the Mortgage Files have been delivered to the
Trustee and the Trustee has conducted a preliminary review of the Mortgage
Files. The Trustee further acknowledges that such review included a review of
the Mortgage Notes (or lost note affidavits and indemnities) to determine that
the appropriate Mortgage Notes (or lost note affidavits and indemnities) have
been delivered and endorsed in the manner set forth in Section 2.1(i). In
connection with such review, the Trustee shall have delivered an exceptions
report indicating any discrepancies relating to such review. In addition, the
Trustee agrees, for the benefit of Certificateholders, to review each Mortgage
File within 45 days, or with respect to assignments which must be recorded,
within 180 days, after execution of this Agreement to ascertain that all
required documents set forth in items (i), (ii), (v), (vi) and, to the extent
delivered to the Trustee, items (iii), (iv), (vii) and (viii) of Section 2.1
have been executed and received, and that such documents relate to the Loans
identified in Exhibit D annexed hereto, and in so doing the Trustee may rely on
the purported due execution and genuineness of any such document and on the
purported genuineness of any signature thereon. The Trustee shall have no duty
to verify or determine whether any Mortgage File should contain documents
described in Sections 2.1(iii), (iv), (vii) and (viii). The Trustee shall be
under no duty or obligation to inspect, review or make any independent
examination of any documents contained in each Mortgage File beyond the review
specifically required herein. The Trustee makes no representations as to (i) the
validity, legality, sufficiency, enforceability or genuineness of any of the
documents contained in each Mortgage File or any of the Loans identified on the
Loan Schedule, or (ii) the collectability, insurability, effectiveness or
suitability of any such Loan. If at the conclusion of such 45-day period or
180-day period the Trustee finds any

                                       36

<PAGE>

document constituting a part of a Mortgage File not to have been executed or
received or to be unrelated to the Loans identified in said Exhibit D (each such
finding, a "material defect"), the Trustee shall promptly notify the Depositor,
which shall have a period of 90 days after the REMIC has received notice to
correct or cure any such material defect; provided, however, that if the Trustee
shall not have received a document by reason of the fact that such document
shall not have been returned by the appropriate recording office then the
Depositor shall have until a date one year later from the Cut-Off Date to
correct or cure such defect. The Depositor hereby covenants and agrees that, if
any such material defect as defined above is not corrected or cured, the
Depositor will, within 90 days of the REMIC having received notice, either (i)
repurchase the related Loan at a price equal to 100% of the Principal Balance of
such Loan (or any property acquired in respect thereof) plus accrued interest on
such Principal Balance at the applicable Pass-Through Rate to the next scheduled
Due Date of such Loan or (ii) substitute for any Loan to which such material
defect relates a different mortgage loan (a "Substitute Loan") maturing no later
than and not more than two years earlier than the Loan being substituted for and
having a principal balance equal to or less than and a Mortgage Interest Rate
equal to or greater than the Mortgage Interest Rate of the Loan being
substituted for, a Loan-to-Value Ratio equal to or less than the Loan-to-Value
Ratio of the Loan being substituted for and otherwise having such
characteristics so that the representations and warranties of the Depositor set
forth in Section 2.3 hereof would not have been incorrect had such Substitute
Loan originally been a Loan; provided, however, that if the Principal Balance of
the original Loan exceeds the principal balance of the Substitute Loan, an
amount equal to that difference shall be deposited by the Depositor in the
Certificate Account; provided, further, however, that no such substitution may
occur after 90 days of the Closing Date unless the Trustee shall have received
from the Depositor an Opinion of Counsel to the effect that such substitution
will not adversely affect the REMIC status of REMIC I or REMIC II or constitute
a prohibited transaction or substitution under the REMIC provisions of the Code,
and, if applicable, within the meaning of the REMIC Provisions of the particular
State, if any, which would impose a tax on the Trust Fund. Monthly Payments due
with respect to Substitute Loans in the month of substitution are not a part of
the Trust Fund and will be retained by the Servicer. The Depositor shall notify
each Rating Agency of any such substitution. For the month of substitution,
distributions to Certificateholders will include the Monthly Payment due on the
Loan being substituted for in such month. The purchase price for the repurchased
Loan or property shall be deposited by the Depositor in the Certificate Account
and in the case of a Substitute Loan, the Mortgage File relating thereto shall
be delivered to the Trustee or the Custodian. Upon receipt by the Trustee of
written notification of such deposit signed by a Servicing Officer or the new
Mortgage File, as the case may be, and an Officer's Certificate that such
repurchase or substitution is in accordance with this Agreement, the Trustee
shall release or cause to be released to the Depositor the related Mortgage File
for the Loan being repurchased or substituted for, as the case may be, and shall
execute and deliver or cause to be executed and delivered such instrument of
transfer or assignment presented to it by the Depositor, in each case without
recourse, as shall be necessary to transfer to the Depositor the Trustee's
interest in such original or repurchased Loan or property and the Trustee shall
have no further responsibility with regard to such Loan. It is understood and
agreed that the obligation of the Depositor to substitute a new Loan for or
repurchase any Loan or property as to which such a material defect in a
constituent document exists shall constitute the sole remedy respecting such
defect available to Certificateholders or the Trustee on behalf of
Certificateholders, but such obligation shall survive termination of this
Agreement. Neither the Trustee nor the Custodian

                                       37

<PAGE>

shall be responsible for determining whether any assignment or mortgage
delivered pursuant to Section 2.1(ii) is in recordable form or, if recorded,
has been properly recorded.

Depositor hereby represents and warrants to the Trustee as of the Closing Date:

         (c) such other matters to which like properties are commonly subject
         which do not individually, or in the aggregate, materially interfere

              (x) that as of the initial issuance of the Certificates, neither

         the best of the Depositor's knowledge, there is no default, breach,
         violation or event of acceleration existing under the Mortgage or the
         related Mortgage Note and no event which, with the passage of time or
         with notice and the expiration of any grace or cure period, would
         constitute a default, breach, violation or event of acceleration; and

         excess of 95%;

               (xvii) the Loans were not selected in manner to adversely affect
         the interests of the Certificateholders and the Depositor knows of no
         conditions which reasonably would cause it to expect any Loan to become
         delinquent or otherwise lose value;

               (xviii) each Loan was either (A) originated directly by or closed
         in the name of either: (i) a savings and loan association, savings

         institution which is supervised and examined by a federal or state

         Section 860G of the Code without regard to ss. 1.860G-2(f) of the REMIC
         Provisions or any similar rule;

               (xx) each Loan that has a Loan-to-Value Ratio in excess of 80% is
         covered by a primary mortgage insurance policy; and

               (xxi) that no Loan permits negative amortization or the deferral
         of accrued interest.

         It is understood and agreed that the representations and warranties set
forth in this Section 2.3 shall survive delivery of the respective Mortgage
Files to the Trustee, or to a Custodian, as the case may be. Upon discovery by
the Depositor, Servicer, the Trustee or any Custodian of a breach of any of the
foregoing representations and warranties (referred to herein as a "breach"),
without regard to any limitation set forth in such representation or warranty
concerning the knowledge of the Depositor as to the facts stated therein, which
breach materially and adversely affects the interests of the Certificateholders
in the related Loan, the party discovering such breach shall give prompt written
notice to the others and to each Rating Agency.

         Within 90 days of its discovery or its receipt of notice of breach, the
Depositor shall cure or shall cause such breach to be cured in all material
respects or shall repurchase the Loan or any property acquired in respect
thereof from the Trustee at a repurchase price equal to 100% of the Principal
Balance of such Loan plus accrued interest on such Principal Balance at the
Mortgage Interest Rate to the next scheduled Installment Due Date of such Loan
or remove such Loan from the Trust Fund and substitute in its place a Substitute
Loan or Loans with the characteristics set forth in Section 2.2 above for
Substitute Loans; provided, however, that if such breach would cause the Loan to
be other than a "qualified mortgage" as defined in Section 860G(a)(3) of the
Code, any such cure, repurchase or substitution must occur within 90 days from
the date such

                                       40

<PAGE>

breach was discovered; provided, further, that no substitution (or cure which
would constitute a loan modification for federal income tax purposes) may be
effected any later than two years after the Closing Date; provided, further,
that as a pre-condition to any substitution (or cure which would constitute
a loan modification for federal income tax purposes) to be effected
later than 90 days after the Closing Date (and within two years of the Closing
Date), the Trustee shall receive from the Depositor an Opinion of Counsel to the
effect that such substitution (or cure which would constitute a loan
modification for federal income tax purposes) will not adversely affect the
REMIC status of REMIC I or REMIC II or constitute a prohibited transaction under
the REMIC Provisions of the Code and, if applicable, the REMIC provisions of the
relevant State. Except as expressly set forth herein, neither the Trustee nor
the Servicer is under any obligation to discover any breach of the above
mentioned representations and warranties. It is understood and agreed that the
obligation of the Depositor to repurchase or substitute any Loan or property as
to which a breach has occurred and is continuing shall constitute the sole
remedy respecting such breach available to Certificateholders or the Trustee on
behalf of Certificateholders, and such obligation shall survive as the
obligation of the Depositor or its respective successors.

         Section 2.4 Authentication and Delivery of Certificates; Designation of
Certificates as REMIC Regular and Residual Interests.

         (a) The Trustee acknowledges the transfer to the extent provided herein
and assignment to it of the Trust Fund and, concurrently with such transfer and
assignment, has caused to be authenticated and delivered to or upon the order of
the Depositor, in exchange for the Trust Fund, Certificates evidencing the
entire ownership of the Trust Fund.

         (b) This Agreement shall be construed so as to carry out the intention
of the parties that each of REMIC I and REMIC II be treated as a REMIC at all
times prior to the date on which the Trust Fund is terminated. The "regular
interests" (within the meaning of Section 860G(a)(1) of the Code) in REMIC II
shall consist of the Class A Certificates and the Subordinate Certificates. The
"residual interest" (within the meaning of Section 860G(a)(2) of the Code) in
REMIC II shall consist of Component R-2 of the Class R Certificates. The
"regular interests" (within the meaning of Section 860G(a)(1) of the Code) of
REMIC I shall consist of Class A-1 Regular Interest, the Class A-2 Regular
Interest, the Class A-3 Regular Interest, the Class A-4 Regular Interest, the
Class A-5 Regular Interest, the Class A-6 Regular Interest, the Class A-7
Regular Interest, the Class A-8 Regular Interest, the Class A-9 Regular
Interest, the Class A-X Regular Interest, the Class A-P Regular Interest, the
Class M Regular Interest, the Class B-1 Regular Interest, the Class B-2 Regular
Interest, the Class B-3 Regular Interest, the Class B-4 Regular Interest and the

the Class R Certificates.

         (c) All payments with respect to each of the A-1, A-2, A-3, A-4, A-5,
A-6, A-7, A-8, A-9, A-X, A-P, M, B-1, B-2, B-3, B-4 and B-5 Certificates shall
each be considered to have been made solely from the Regular Interest of REMIC I
having the same designation. All principal payments with respect to each such
Class of Certificates (other than the Class A-X Certificates) shall be
considered to have been made solely from the principal payments of the
corresponding Regular Interests of REMIC I, and the Class Principal Balance of
each such Class of Certificate (other than the Class A-X Certificates) shall be
equal at all times to the principal balance of each

                                       41

<PAGE>

such corresponding Regular Interest of REMIC I. All interest payments
with respect to the Class A-X Certificates shall be considered to have been made
solely from the interest payments of the Class A-X Regular Interest of REMIC I,
and the notional principal amount of the Class A-X Regular Interest shall be
equal at all times to the Class A-X Notional Amount. The interest rate of each
REMIC I Regular Interest Class A-1, A-2, A-3, A-4, A-5, A-6, A-7, A-8, A-9, A-X,
M, B-1, B-2, B-3, B-4 and B-5 shall be 6.75%. The Class A-P Regular Interest
Class shall not bear interest, but will receive principal only in respect of the
Loans.

         (d) The Class A-10 Certificates shall be considered for federal income
tax purposes to have two component notional principal amounts: (i) the principal
balance of the Class A-1 Regular Interest, bearing interest at 0.75%, and (ii)
the principal balance of the Class A-5 Regular Interest, bearing interest at
0.25%.

         Section 2.5 Designation of Startup Day. The Closing Date is hereby
designated as the "startup day" of each of REMIC I and REMIC II within the
meaning of Section 860G(a)(9) of the Code.

         Section 2.6 No Contributions. The Trustee shall not accept or make any
contribution of cash to the Trust Fund after 90 days of the Closing Date, and
shall not accept or make any contribution of other assets to the Trust Fund
unless, in either case, it shall have received an Opinion of Counsel to the
effect that the inclusion of such assets in the Trust Fund will not cause either
REMIC I or REMIC II to fail to qualify as a REMIC at any time that any Class A
or Subordinate Certificates are outstanding or subject the Trust Fund to any tax
on contributions to the REMIC under Section 860G(d) of the Code.

         Section 2.7 Representations and Warranties of the Servicer. The
Servicer hereby represents, warrants and covenants to the Trustee for the
benefit of Certificateholders that, as of the date of execution of this
Agreement:

               (a) the Servicer is a corporation duly formed and validly
         existing under the laws of the State of Delaware;

               (b) the execution and delivery of this Agreement by the Servicer
         and its performance of and compliance with the terms of this Agreement
         will not violate the Servicer's corporate charter or by-laws or
         constitute a default (or an event which, with notice or lapse of time,
         or both, would constitute a default) under, or result in the breach of,
         any material contract, agreement or other instrument to which the
         Servicer is a party or which may be applicable to the Servicer or any
         of its assets;

               (c) this Agreement, assuming due authorization, execution and
         delivery by the Trustee and the Depositor, constitutes a valid, legal
         and binding obligation of the Servicer, enforceable against it in
         accordance with the terms hereof subject to applicable bankruptcy,
         insolvency, reorganization, moratorium and other laws affecting the
         enforcement of creditors' rights generally and to general principles of
         equity, regardless of whether such enforcement is considered in a
         proceeding in equity or at law;

               (d) the Servicer is not in default with respect to any order or
         decree of any court or any order, regulation or demand of any federal,
         state, municipal or governmental

                                       42

<PAGE>

         agency, which default might have consequences that would
         materially and adversely affect the condition (financial or other) or
         operations of the Servicer or its properties or might have consequences
         that would affect its performance hereunder; and

               (e) no litigation is pending or, to the best of the Servicer's
         knowledge, threatened against the Servicer which would prohibit its
         entering into this Agreement or performing its obligations under this
         Agreement.

         It is understood and agreed that the representations and warranties set
forth in this Section 2.7 shall survive delivery of the respective Mortgage
Files to the Trustee, or to a Custodian, as the case may be.

                                  ARTICLE III

                      ADMINISTRATION AND SERVICING OF LOANS

         Section 3.1 Servicer to Act as Servicer; Administration of the Loans.

         (a) The Servicer shall service and administer the Loans on behalf of
the Trust Fund solely in the best interests of and for the benefit of the
Certificateholders (as determined by the Servicer in its reasonable judgment)
and the Trustee (as trustee for Certificateholders) in accordance with the terms
of this Agreement and the respective Loans and, to the extent consistent with
such terms, in the same manner in which, and with the same care, skill, prudence
and diligence with which, it services and administers similar mortgage loans for
other portfolios, giving due consideration to customary and usual standards of
practice of prudent institutional residential mortgage lenders and loan
servicers, and taking into account its other obligations hereunder, but without
regard to:

               (i) any relationship that the Servicer, any sub-servicer, any
         special servicer or any Affiliate of the Servicer, any sub-servicer or
         any special servicer may have with the related Mortgagor;

               (ii) the ownership of any Certificate by the Servicer, any
         special servicer or any Affiliate of the Servicer, any sub-servicer or
         any special servicer;

               (iii) the Servicer's, any sub-servicer's or any special
         servicer's right to receive compensation for its services hereunder or
         with respect to any particular transaction; or

               (iv) the ownership, or servicing or management for others, by the
         Servicer, any sub-servicer or any special servicer, of any other
         mortgage loans or property.

In addition, the Servicer shall have full power and authority to do or cause to
be done any and all things in connection with such servicing and administration
which it may deem necessary or desirable, including, without limitation, the
power and authority to bring actions and defend the Trust Fund on behalf of the
Trustee in order to enforce the terms of the Mortgage Notes. The Servicer may
perform its servicing responsibilities through agents or independent
contractors, but shall not thereby be released from any of its responsibilities
hereunder and the Servicer shall diligently pursue all of its rights against
such agents or independent contractors.

                                       43
<PAGE>

         To the extent consistent with the foregoing and subject to any express
limitations set forth in this Agreement, the Servicer shall seek to maximize the
timely and complete recovery of principal and interest on the Mortgage Notes;
provided, however, that nothing herein contained shall be construed as an
express or implied guarantee by the Servicer of the collectability of the Loans.
Subject only to the above-described servicing standards and the terms of this
Agreement and of the respective Loans, the Servicer, as an independent
contractor, shall service and administer the Loans and shall have full power and
authority, acting alone or through one or more subservicers, special servicers
or agents (subject to paragraph (c) of this Section 3.1), to do any and all
things in connection with such servicing and administration which it may deem
necessary or desirable for the purpose of conserving the assets of the Trust
Fund. Without limiting the generality of the foregoing, the Servicer shall and
is hereby authorized and empowered by the Trustee to continue to execute and
deliver, on behalf of itself, the Certificateholders and the Trustee or any of
them, any and all financing statements, continuation statements and other
documents or instruments necessary to maintain the lien on each Mortgaged
Property and related collateral; and modifications, waivers, consents or
amendments to or with respect to any documents contained in the related Mortgage
File; and any and all instruments of satisfaction or cancellation, or of partial
or full release or discharge, assignments of Mortgages and endorsements of Notes
in connection with refinancings (in jurisdictions where such assignments are the
customary and usual standard of practice of mortgage lenders) and all other
comparable instruments, with respect to the Loans and with respect to the
related Mortgaged Properties. Notwithstanding the foregoing, the Servicer
(whether acting alone or through one or more subservicers, special servicers or
agents) shall not modify, amend, waive or otherwise consent to the change of the
terms of any of the Loans (including without limitation extending the stated
maturity date of any Loan or forgiving principal of or interest on any Loan),
except as permitted by Section 3.2 hereof. The Servicer shall service and
administer the Loans in accordance with applicable law and shall provide to the
Mortgagors any reports required to be provided to them thereby. To enable the
Servicer to carry out its servicing and administrative duties hereunder, upon
the Servicer's written request accompanied by the forms of any documents
requested, the Trustee shall execute and deliver to the Servicer any powers of
attorney and other documents necessary or appropriate and the Trustee shall not
be responsible for releasing such powers of attorney. The Trustee shall not be
responsible for, and the Servicer shall indemnify the Trustee for, any action
taken by the Servicer pursuant to the application of any such power of attorney.
The relationship of the Servicer (and of any successor thereto) 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.

         In connection with the servicing and administration of each Loan, the
Servicer and any affiliate of the Servicer (i) may perform services such as
appraisals, default management and brokerage services that are not customarily
provided by servicers of mortgage loans, and shall be entitled to reasonable
compensation therefore not in excess of market rates for such services and (ii)
may, at its own discretion and on behalf of the Trustee, obtain credit
information in the form of a "credit score" from a credit repository.

         (b) The Servicer, Trustee and Depositor intend that REMIC I and REMIC
II formed hereunder shall constitute, and that the Servicer shall perform its
duties and obligation hereunder so as to qualify each of them as, a "real estate
mortgage investment conduit" as defined in and in accordance with the REMIC
Provisions. The Tax Matters Person, or the Person acting as

                                       44

<PAGE>

attorney-in-fact and agent therefor, shall: (a) prepare and file, or
cause to be prepared and filed, federal tax returns (as well as any other
federal and state information and other returns) using a calendar year as the
taxable year when and as required by the REMIC Provisions; (b) make (or cause to
be made) an election, on behalf of each of REMIC I and REMIC II, to be treated
as a REMIC on the Federal tax return and any applicable state or local returns
for the first taxable year, in accordance with the REMIC Provisions; (c) prepare
and forward, or cause to be prepared and forwarded, to the Certificateholders
all information reports (including, without limitation, the information required
in connection with the computation of the present value of anticipated excess
inclusions as required by ss. 1.860E-2(a)(5) of the REMIC Provisions) as and
when required to be provided to them in accordance with the REMIC Provisions;
(d) conduct the affairs of the Trust Fund at all times that REMIC I Regular
Interests or REMIC II Certificates are outstanding so as to maintain the status
of each of REMIC I and REMIC II as a REMIC under the REMIC Provisions; and (e)
not knowingly or intentionally take any action or omit to take any action that
would cause the termination of the REMIC status of either REMIC I or REMIC II.

         The Servicer may enter into sub-servicing agreements with third parties
with respect to any of its respective obligations hereunder, provided, that any
such agreement shall be consistent with the provisions of this Agreement. Any
such sub-servicing agreement may permit the sub-servicer to delegate its duties
to agents or subcontractors so long as the related agreements or arrangements
with such agents or subcontractors are consistent with the provisions of this
Section 3.1(c).

         Any sub-servicing agreement, and any other transactions or services
relating to the Loans involving a sub-servicer, including (if applicable) the
Depositor in its capacity as sub-servicer under a sub-servicing agreement and
not in its capacity as a party to this Agreement, shall be deemed to be between
the Servicer and such sub-servicer (including the Depositor) alone, and the
Trustee and the Certificateholders shall not be deemed parties thereto and shall
have no claims, rights, obligations, duties or liabilities with respect to the
sub-servicer, except as set forth in Section 3.1(d).

         In the event that the Trustee assumes the servicing obligations of the
Servicer (including by reason of an Event of Default which is not cured by the
Servicer within the time permitted hereunder), upon request of the Trustee, the
Servicer shall at its own expense deliver to the Trustee all documents and
records relating to any sub-servicing agreement and the Loans then being
serviced thereunder and an accounting of amounts collected and held by it, if
any, and will otherwise use its best efforts to effect the orderly and efficient
transfer of any sub-servicing agreement to the Trustee.

         (c) Costs incurred by the Servicer in effectuating the timely payment
of taxes and assessments on the Mortgaged Property securing a Mortgage Note
shall be recoverable by the Servicer pursuant to Section 3.3. The Servicer shall
ensure all such taxes and assessments are timely paid.

         The Servicer, as initial servicer, shall pay all of its costs and
proven damages incurred with respect to or arising out of any allegation of
impropriety in its servicing of the Loans. Further, the Servicer shall not be
entitled to reimbursement or indemnification from either the Trust Fund or the
Certificateholders with respect to any such costs, claims and damages.

                                       45

<PAGE>

         (d) Notwithstanding any sub-servicing agreement, any of the provisions
of this Agreement relating to agreements or arrangements between the Servicer
and any Person (including the Depositor) acting as sub-servicer (or its agents
or subcontractors) or any reference to actions taken through any Person
(including the Depositor) acting as sub-servicer or otherwise, the Servicer
shall remain obligated and primarily liable to the Trustee and
Certificateholders for the servicing and administering of the Loans in
accordance with the provisions of this Agreement without diminution of such
obligation or liability by virtue of such sub-servicing agreements or
arrangements or by virtue of indemnification from the Depositor or any other
Person acting as sub-servicer (or its agents or subcontractors) to the same
extent and under the same terms and conditions as if the Servicer alone were
servicing and administering the Loans. The Servicer shall be entitled to enter
into an agreement with any sub-servicer providing for indemnification of the
Servicer by such sub-servicer (including the Depositor and the Trustee), and
nothing contained in this Agreement shall be deemed to limit or modify such
indemnification, but no such agreement for indemnification shall be deemed to
limit or modify this Agreement.

         Section 3.2 Collection of Certain Loan Payments; Custodial Account for
                     P&I.

         (a) The Servicer shall make reasonable efforts to collect all payments
called for under the terms and provisions of the Loans, and shall, to the extent
such procedures shall be consistent with this Agreement, follow such collection
procedures as it follows with respect to conventional mortgage loans it services
for itself and any of its Affiliates; provided, however, that the Servicer
agrees not to permit any modification with respect to any Loan that would change
the manner in which the Mortgage Interest Rate is computed, forgive any
principal or interest or change the term of such Loan. Consistent with the
foregoing, the Servicer may in its discretion (i) waive any assumption fee, late
payment charge or other charge in connection with a Loan, and (ii) arrange a
schedule, running for no more than 180 days after the scheduled Due Date, for
payment of any installment on any Mortgage Note or after the due date of any
other payment due under the related Mortgage Note for the liquidation of
delinquent items, provided, that the Servicer shall continue to be obligated to
make Advances in accordance with Section 4.3 during the continuance of such
period. With respect to any Loans which provide for the right of the holder
thereof to call for early repayment thereof at times specified therein, neither
the Trustee nor the Servicer shall exercise any such right, except that the
Trustee shall exercise such right at the written direction of the Servicer set
forth in an Officer's Certificate in connection with a default under the related
Note. Notwithstanding anything herein to the contrary, neither the Servicer nor
any other party may take any action that would cause a "significant
modification" of any Loan within the meaning of the REMIC Provisions that would
cause REMIC I or REMIC II to fail to qualify as a REMIC at any time or cause a
tax to be imposed on the Trust Fund under the REMIC Provisions.

         (b) The Servicer shall establish and maintain a separate account as set
forth in Article I (the "Custodial Account for P&I"), and shall on the Closing
Date credit any amounts representing scheduled payments of principal and
interest due after the Cut-off Date but received by the Servicer on or before
the Closing Date, and thereafter on a daily basis the following payments and
collections received or made by it (other than in respect of principal of and
interest on the Loans due on or before the Cut-off Date):

                                       46
<PAGE>

               (i) All Mortgagor payments on account of principal, including
         Principal Prepayments on the Loans;

               (ii) All Mortgagor payments on account of interest on the Loans,
         which may be net of that portion thereof which the Servicer is entitled
         to retain as Servicing Fees (adjusted for any amounts related to
         Compensating Interest) pursuant to Section 3.9, as adjusted pursuant to
         Section 4.6;

               (iii) All net Liquidation Proceeds;

               (iv) All Insurance Proceeds received by the Servicer, other than
         proceeds to be applied to the restoration or repair of the property
         subject to the related Mortgage or released to the Mortgagor in
         accordance with the Servicer's normal servicing procedures, and all
         amounts deposited by the Servicer with respect to the failure to
         maintain flood or fire and hazard insurance policies, pursuant to
         Section 3.5;

               (v) All repurchase proceeds from the repurchase of a Loan
         pursuant to a Purchase Obligation;

               (vi) any amounts required to be deposited pursuant to Section
         3.2(c) in connection with net losses realized on Eligible Investments
         with respect to funds held in the Custodial Account for P&I;

               (vii) all income and gain realized from any investment of the
         funds in the Custodial Account for P&I in Eligible Investments;

               (viii) all net income from the renting of REO Property pursuant
         to Section 3.7(c); and

               (ix) All other amounts required to be deposited in the Custodial
         Account for P&I pursuant to this Agreement.

         (c) The Servicer may invest the funds in the Custodial Account for P&I
in Eligible Investments which shall mature not later than the Business Day
preceding the next Distribution Date unless the Custodial Account for P&I is
maintained with the Trustee in which case they may mature on the Distribution
Date. The Eligible Investments may not be sold or disposed of prior to their
maturity. All such Eligible Investments shall be made in the name of the
Servicer (in its capacity as such) or its nominee. All income and gain realized
from any such investment shall be for the benefit of the Servicer, and shall be
payable to the Servicer. The amount of any losses incurred in respect of any
such investments shall be deposited in the Custodial Account for P&I by the
Servicer, out of its own funds immediately as realized without right to
reimbursement therefor.

         (d) The foregoing requirements for deposit in the Custodial Account for
P&I shall be exclusive, it being understood and agreed that, without limiting
the generality of the foregoing, payments in the nature of those described in
the last paragraph of this Section 3.2 and payments in the nature of late
payment charges or assumption fees need not be deposited by the Servicer in the
Custodial Account for P&I. All funds deposited by the Servicer in the Custodial
Account for

                                       47

<PAGE>

P&I shall be held by it in trust in the Custodial Account for P&I until
disbursed in accordance with Section 4.1 or withdrawn in accordance with
Section 3.3; provided, however, that the Servicer shall withdraw such funds and
deposit them in such manner as to not result in a downgrading or withdrawal of
the rating then assigned to the Certificates by each Rating Agency. If the
Servicer deposits in the Custodial Account for P&I any amount not required to be
deposited therein, it may at any time withdraw such amount from the Custodial
Account for P&I pursuant to Section 3.3(i) of this Agreement.

         Certain of the Loans may provide for payment by the Mortgagor of
amounts to be used for payment of taxes, assessments, hazard or other insurance
premiums or comparable items for the account of the Mortgagor. The Servicer may
deal with these amounts in accordance with its normal servicing procedures.

         Section 3.3 Permitted Withdrawals from the Custodial Account for P&I.
The Servicer may, from time to time, make withdrawals from the Custodial Account
for P&I and the Certificate Account for the following purposes:

             (a)  to reimburse itself for Advances made by or on behalf of it
         pursuant to Section 3.4 or 4.3, the Servicer's right to reimburse
         itself pursuant to this subclause (a) being limited to (i) amounts
         received on or in respect of particular Loans (including, for this
         purpose, Liquidation Proceeds and Insurance Proceeds which represent
         late recoveries of payments of principal and/or interest respecting
         which any such Advance was made and any net income received from the
         renting of REO Property pursuant to Section 3.7(c)) and (ii) amounts in
         the Custodial Account for P&I held for future distribution or
         withdrawal, such amounts referred to in clause (ii) of this subclause
         (a) to be replaced by the Servicer to the extent that funds in the
         Custodial Account for P&I on a future Withdrawal Date are less than the
         payment required to be made to the Certificate Account therefrom as of
         such future Distribution Date;

             (b) (i) to reimburse itself from Liquidation Proceeds for
         Liquidation Expenses, (ii) for amounts expended by it pursuant to
         Section 3.7 in good faith in connection with the restoration of damaged
         property and (iii) to the extent that Liquidation Proceeds after such
         reimbursement are in excess of the Principal Balance of the related
         Loan together with accrued and unpaid interest thereon at the
         applicable Pass-Through Rate to the date of such liquidation, net of
         any related Advances which were unreimbursed prior to the receipt of
         such Liquidation Proceeds, to pay to itself any unpaid Servicing Fees,
         and any assumption fees, late payment charges or other Mortgage charges
         on the related Loan;

             (c) to pay to itself from any Mortgagor payment as to interest or
         other recovery with respect to a particular Loan, to the extent
         permitted by this Agreement, that portion of any payment as to interest
         in excess of interest at the applicable Pass-Through Rate which the
         Servicer is entitled to retain as Servicing Fees pursuant to Section
         3.9 or otherwise;

             (d) to reimburse itself for expenses incurred by and recoverable
         by or reimbursable to it pursuant to Section 3.1 or 3.5 after the
         related Mortgagor has

                                       48

<PAGE>
         reimbursed the Trust Fund for such expenses or following
         liquidation of the related Loan, or pursuant to Section 6.3;

               (e) to pay to itself with respect to each Loan or property
         acquired in respect thereof that has been repurchased pursuant to
         Section 2.2 or 2.3 or purchased by the Class R Certificateholders
         pursuant to Section 9.1 all amounts received thereon and not
         distributed as of the date on which the related Principal Balance is
         determined;

               (f) to reimburse itself for any Nonrecoverable Advances;

               (g) to disburse to the Trustee in order that the Trustee may make
         payments to Certificateholders in the amounts and in the manner
         provided for in Section 4.1;

               (h) to pay itself any net interest or other income earned and
         received on or investment income received with respect to funds in the
         Custodial Account for P&I; and

               (i) to make payments to itself or others pursuant to any
         provision of this Agreement and to remove any amounts not required to
         be deposited therein and to clear and terminate the Custodial Account
         for P&I pursuant to Section 9.1.

         Since in connection with withdrawals pursuant to subclauses (a), (b),
(c) and (e) the Servicer's entitlement thereto is limited to collections or
other recoveries on the related Loan, the Servicer shall keep and maintain a
separate accounting for each Loan for the purpose of justifying any withdrawal
from the Custodial Account for P&I pursuant to such subclauses.

         The Servicer shall make the withdrawal referred to in subclause (g)
above and shall deposit the amount so withdrawn into the Certificate Account
prior to 4:00 P.M. New York City time on each related Withdrawal Date.

         The Servicer may establish, or cause to be established, two or more
Custodial Accounts for P&I into which funds collected by the Servicer or its
subservicers in connection with the Loans may be deposited. Funds collected in
connection with mortgage loans other than the Loans may also be deposited in the
Custodial Accounts for P&I and co-mingled with collections on the Loans. The
Servicer may, in its discretion, withdraw funds from one Custodial Account for
P&I and deposit such funds into another Custodial Account for P&I prior to the
date such funds must be deposited in the Certificate Account.

Section 3.4       Taxes, Assessments and Similar Items; Escrow Accounts.

         (a) The Servicer shall establish and maintain one or more accounts
(each, an "Escrow Account") into which all Escrow Payments shall be deposited
and in which all Escrow Payments shall be retained. Escrow Accounts shall be
Eligible Accounts, and funds in the Escrow Account may be invested in Eligible
Investments. Withdrawals of amounts from an Escrow Account may be made only to:
(i) effect payment of taxes, assessments, insurance premiums and comparable
items; (ii) refund to Mortgagors any sums that are determined to be overages;
(iii) reimbursement to the Servicer for any cost incurred in paying taxes,
insurance premiums and assessments or comparable items; (iv) pay interest, if
required and as described below, to Mortgagors on balances in the Escrow
Account; (v) withdraw interest or other income which may lawfully be

                                       49

<PAGE>

retained by the Trust Fund, for deposit into the Certificate Account;
or (vi) clear and terminate the Escrow Account at the termination of this
Agreement in accordance with Section 9.1. Unless otherwise required by
applicable law, any interest earned on funds in Escrow Accounts shall be
remitted to the related Mortgagors if required by the related Mortgage Note or
otherwise to the Servicer as additional servicing compensation.

         (b) With respect to each Loan, the Servicer shall maintain, or cause to
be maintained, accurate records with respect to each related Mortgaged Property
reflecting the status of taxes, assessments and other similar items that are or
may become a lien on the related Mortgaged Property and the status of insurance
premiums payable with respect thereto. The Servicer shall require that payments
for taxes, assessments, insurance premiums and other similar items be made by
the Mortgagor at the time they first become due. If a Mortgagor fails to make
any such payment on a timely basis, the Servicer shall advance, or cause to be
advanced, the amount of any shortfall unless the Servicer determines in its good
faith judgment that such advance would not be ultimately recoverable from future
payments and collections on the related Loan (including without limitation
Insurance Proceeds and Liquidation Proceeds), or otherwise. The Servicer shall
be entitled to reimbursement of advances made pursuant to the preceding
sentence, together with interest thereon at the Federal Funds Rate, from amounts
received on or in respect of the related Loan respecting which such advance was
made or if such advance has become nonrecoverable, in either case to the extent
permitted by Section 3.3 of this Agreement. No costs incurred by the Servicer in
effecting the payment of taxes and assessments on the Mortgaged Properties
shall, for the purpose of calculating distributions to Certificateholders, be
added to the amount owing under the related Loans, notwithstanding that the
terms of such Loans so permit.

         The Servicer may establish, or cause to be established, two or more
Escrow Accounts into which funds collected by the Servicer or its subservicers
in connection with the Loans may be deposited. Funds collected in connection
with mortgage loans other than the Loans may also be deposited in the Escrow
Accounts and co-mingled with collections on the Loans. The Servicer may, in its
discretion, withdraw funds from one Escrow Account and deposit such funds into
another Escrow Account prior to the date such funds must be used to make Escrow
Payments.

         Section 3.5 Maintenance of Insurance. The Servicer shall also cause to
be maintained for each Loan fire and hazard insurance with extended coverage as
is customary in the area where the Mortgaged Property is located in an amount
which is at least equal to the lesser of (i) the Principal Balance of such Loan
or (ii) the replacement value costs of improvements securing such Loan. The
Servicer shall cause to be maintained fire and hazard insurance with extended
coverage on each REO Property in an amount which is at least equal to the
greater of (i) an amount not less than is necessary to avoid the application of
any co-insurance clause contained in the related fire and hazard insurance
policy or (ii) the replacement cost of the improvements which are a part of such
property. The Servicer shall also cause to be maintained for each Loan with a
Loan-to-Value Ratio greater than 80% a primary mortgage insurance policy which
will cover at least 75% of the original fair market value of the related
Mortgaged Property until such time as the principal balance of such Loan is
reduced to 80% of the current fair market value or otherwise in accordance with
applicable law. The Servicer on behalf of the Trustee as Mortgagee shall
maintain or cause the related Mortgagor to maintain for each Loan such other
insurance on the related Mortgaged Property as may be required by the terms of
the related

                                       50

<PAGE>

Mortgage Note. If the Mortgaged Property is in an area identified in the
Federal Register by the Flood Emergency Management Agency as having special
flood hazards the Servicer will cause to be maintained a flood insurance policy
meeting the requirements of the current guidelines of the Federal Insurance
Administration with a generally acceptable insurance carrier, in an amount
representing coverage not less than the least of (i) the full insurable value,
(ii) the maximum amount of insurance which is available under the Flood Disaster
Protection Act of 1973, and (iii) the Principal Balance of the related Loan. The
Servicer shall also maintain fire and hazard insurance with extended coverage
and, if applicable, flood insurance on property acquired upon foreclosure, or by
deed in lieu of foreclosure, of any Loan in an amount that is at least equal to
the lesser of (i) the maximum insurable value of the improvements which are a
part of such property and (ii) the principal balance owing on such Loan at the
time of such foreclosure or grant of deed in lieu of foreclosure plus accrued
interest and related Liquidation Expenses. If an REO Property was located at the
time of origination of the related Loan in a federally designated special flood
hazard area, the Servicer will obtain flood insurance in respect thereof
providing substantially the same coverage as described in the preceding
sentence. If at any time during the term of this Agreement a recovery under a
flood or fire and hazard insurance policy in respect of an REO Property is not
available but would have been available if such insurance were maintained
thereon in accordance with the standards applied to Mortgaged Properties
described herein, the Servicer shall either (i) immediately deposit into the
Custodial Account for P&I from its own funds the amount that would have been
recovered or (ii) apply to the restoration and repair of the property from its
own funds the amount that would have been recovered, if such application would
be consistent with the servicing standard set forth in Section 3.1. It is
understood and agreed that such insurance shall be with insurers approved by the
Servicer and that no earthquake or other additional insurance is to be required
of any Mortgagor, other than pursuant to such applicable laws and regulations or
policies of the Servicer as shall at any time be in force and as shall require
such additional insurance. Pursuant to Section 3.2, any amounts collected by the
Servicer under any insurance policies maintained pursuant to this Section 3.5
(other than amounts to be applied to the restoration or repair of the property
subject to the related Mortgage or released to the Mortgagor in accordance with
the Servicer's normal servicing procedures) shall be deposited into the
Custodial Account for P&I, subject to withdrawal pursuant to Section 3.3. Any
cost incurred by the Servicer in maintaining any such insurance shall be
recoverable by the Servicer pursuant to Section 3.3. In the event that the
Servicer shall obtain and maintain a blanket policy issued by an insurer that
qualifies under the guidelines set forth for the Servicer by FNMA or FHLMC,
insuring against hazard losses on all of the Loans, then, to the extent such
policy provides coverage in an amount equal to the unpaid principal balance on
the Loans without co-insurance and otherwise complies with all other
requirements set forth in the first paragraph of this Section 3.5, it shall
conclusively be deemed to have satisfied its obligation as set forth in such
first paragraph, it being understood and agreed that such policy may contain a
deductible clause, in which case the Servicer shall, in the event that there
shall not have been maintained on the related mortgaged or acquired property an
insurance policy complying with the first paragraph of this Section 3.5 and
there shall have been a loss which would have been covered by such a policy had
it been maintained, be required to deposit from its own funds into the Custodial
Account for P&I or apply to the restoration of the property the amount not
otherwise payable under the blanket policy because of such deductible clause.

         The Servicer shall obtain and maintain at its own expense throughout
the term of this Agreement a blanket fidelity bond and an errors and omissions
insurance policy with broad

                                       51

<PAGE>

coverage with responsible companies covering the Servicer's officers and
employees and other persons acting on behalf of the Servicer in connection
with its activities under this Agreement. Any such fidelity bond and errors and
omissions insurance shall provide an amount of coverage and will maintain such
coverage at a level which will permit the Servicer to continue to be a FNMA or a
FHLMC-qualified Servicer and shall protect and insure the Servicer against
losses, including forgery, theft, embezzlement, fraud, errors and omissions and
negligent acts of such persons. No provision of this Section 3.5 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.

         Section 3.6 Enforcement of Due-on-Sale Clauses; Assumption and
Substitution Agreements. In any case in which property subject to a Mortgage is
conveyed by the Mortgagor, the Servicer will enforce any due-on-sale clause
contained in the related 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
related insurance policy or result in legal action by the Mortgagor. Subject to
the foregoing, the Servicer is authorized to take or enter into an assumption or
substitution agreement from or with the Person to whom such property has been or
is about to be conveyed. The Servicer is also authorized to release the original
Mortgagor from liability upon the Loan and substitute the new Mortgagor as
obligor thereon. In connection with such assumption or substitution, the
Servicer shall apply such underwriting standards and follow such practices and
procedures as shall be normal and usual and as it applies to mortgage loans
owned solely by it or any of its Affiliates. The Servicer shall notify the
Trustee that any such assumption or substitution agreement has been completed by
forwarding to the Trustee the original copy of such assumption or substitution
agreement, which copy shall be added by the Trustee 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.
In connection with any such assumption or substitution agreement, the interest
rate of the related Mortgage Note shall not be changed. Any fee collected by the
Servicer for entering into an assumption or substitution of liability agreement
will be retained by the Servicer as servicing compensation.

         Notwithstanding the foregoing paragraph or any other provision of this
Agreement, the Servicer shall not be deemed to be in default, breach or any
other violation of its obligations hereunder by reason of any conveyance by the
Mortgagor of the Mortgaged Property or any assumption of a Loan by operation of
law which the Servicer in good faith determines it may be restricted by law from
preventing, for any reason whatsoever.

Section 3.7       Realization upon Defaulted Loans.

         (a) Consistent with the servicing standard set forth in Section 3.1 and
with a view to the best economic interest of the Trust Fund, the Servicer shall
foreclose upon or otherwise comparably convert (which may include acquisition of
an REO Property) the Mortgaged Properties securing such of the Loans as come
into and continue in default and as to which no satisfactory arrangements can be
made for collection of delinquent payments pursuant to Section 3.2. In
connection with such foreclosure or other conversion, the Servicer shall follow
such practices and procedures as it shall deem necessary or advisable and as
shall be normal and usual in its general mortgage servicing activities. The
foregoing is subject to the proviso that the

                                       52

<PAGE>

Servicer shall not be required to expend its own funds in connection with
any foreclosure or to restore any damaged property unless it shall
determine (i) that such foreclosure and/or restoration expenses will increase
the Liquidation Proceeds to Certificateholders after reimbursement to itself for
such expenses and (ii) that such expenses will be recoverable to it through
Liquidation Proceeds (respecting which it shall have priority for purposes of
withdrawal from the Custodial Account for P&I pursuant to Section 3.3). Any gain
on foreclosure or other conversion of a Liquidated Loan shall be distributed to
the Class R Certificateholders, but only to the extent that such gain is not
necessary to make distributions to the Certificateholders of the other Classes
of Certificates. The Servicer shall be responsible for all other costs and
expenses incurred by it in any such proceedings; provided, however, that it
shall be entitled to reimbursement thereof (as well as any Servicing Fees and
other amounts due it, if any), to the extent, but only to the extent, that
withdrawals from the Custodial Account for P&I with respect thereto are
permitted under Section 3.3.

         (b) Prior to any such foreclosure, the Servicer may, at its option,
repurchase any Loan which is 90 days or more delinquent and which the Servicer
determines in good faith would otherwise become subject to foreclosure
proceedings or any Loan as to which the Mortgagor tenders a deed in lieu of
foreclosure at a price equal to the outstanding Principal Balance of the Loan
plus accrued interest at the applicable Pass-Through Rate to the next Due Date.
Any such repurchase shall be deemed a Principal Prepayment for purposes of this
Agreement and all amounts in respect thereof shall be deposited into the
Custodial Account for P&I pursuant to Section 3.2(b).

         (c) The Trust Fund shall not acquire any real property (or personal
property incident to such real property) except in connection with a default or
imminent default of a Loan. Based on a report prepared by an Independent Person
who regularly conducts environmental audits that the Mortgaged Property for
which foreclosure proceedings are contemplated is not in compliance with
applicable environmental laws, or there are circumstances present at such
Mortgaged Property relating to the use, management or disposal of any hazardous
materials, wastes, or petroleum based materials for which investigation,
testing, monitoring, containment, clean-up or remediation could be required
under any federal, state or local law or that it would not be in the best
economic interest of the Trust Fund to acquire title to such Mortgaged Property
and further to take such actions as would be necessary and appropriate to effect
such compliance and/or respond to such circumstances, the Servicer will not
conduct such foreclosure proceedings. If the Servicer otherwise becomes aware,
under its customary servicing procedures, of an environmental hazard with
respect to a Loan for which foreclosure proceedings are contemplated, the
Servicer will not conduct such foreclosure proceedings unless it determines in
good faith that the liability associated with the environmental hazard will be
less than the Liquidation Proceeds to be realized from the sale of the related
Mortgaged Property. In the event that the Trust Fund acquires any real property
(or personal property incident to such real property) in connection with a
default or imminent default of a Loan, such REO Property shall be disposed of by
the Trust Fund within three years after its acquisition by the Trust Fund unless
the Trustee shall have received from the Servicer an Opinion of Counsel to the
effect that the holding by the Trust Fund of such REO Property subsequent to
three years after its acquisition will not cause either REMIC I or REMIC II to
fail to qualify as a REMIC under the REMIC Provisions at any time that any REMIC
I Regular Interests or Certificates are outstanding, in which case such REO
Property shall be disposed of as soon as possible by the Trust Fund but in

                                       53

<PAGE>

no event shall be held longer than the maximum period of time during which the
Trust Fund is then permitted to hold such REO Property and allow REMIC I and
REMIC II to remain qualified as REMICs under the REMIC Provisions. The Servicer
shall manage, conserve, protect and operate each such REO Property for the
Certificateholders solely for the purpose of its prompt disposition and sale in
a manner which does not cause such REO Property to fail to qualify as
"foreclosure property" within the meaning of Section 860G(a)(8) of the Code.
Pursuant to its efforts to sell such REO Property, the Servicer shall either
itself or through an agent selected by the Servicer protect and conserve such
REO Property in the same manner and to such extent as is customary in the
locality where such property is located and may, incident to its conservation
and protection of the interests of the Certificateholders, rent the same, or any
part thereof, as the Servicer deems to be in the best interest of the Servicer
and the Certificateholders for the period prior to the sale of such REO
Property. All proceeds from the renting of such REO Property shall, net of any
costs or expenses of the Servicer in connection therewith, be deposited into the
Custodial Account for P&I pursuant to Section 3.3(b)(ix).

         (d) In the event that title to any Mortgaged Property is acquired in
foreclosure or by deed in lieu of foreclosure, the deed or certificate of sale
shall be issued to the Trustee, or to its nominee on behalf of
Certificateholders. Notwithstanding any such acquisition of title and
cancellation of the related Loan, such Loan shall (except for purposes of
Section 9.1) be considered to be a Loan held in the Trust Fund until such time
as the related REO Property shall be sold by the Trust Fund and shall be reduced
only by collections net of expenses. Consistent with the foregoing, for purposes
of all calculations hereunder, so long as such Loan shall be considered to be an
outstanding Loan, it shall be assumed that, notwithstanding that the
indebtedness evidenced by the related Mortgage Note shall have been discharged,
such Mortgage Note and, for purposes of determining the Scheduled Principal
Balance thereof, the related amortization schedule in effect at the time of any
such acquisition of title remain in effect.

         (e) The Servicer shall not acquire for the benefit of the Trust Fund
any personal property pursuant to this Section 3.7 unless either:

               (i) such personal property is incident to real property (within
         the meaning of Section 856(e)(1) of the Code) so acquired by the
         Servicer for the benefit of the Trust Fund; or

               (ii) the Servicer shall have requested and received an Opinion of
         Counsel (which opinion shall be an expense of the Trust Fund) to the
         effect that the holding of such personal property by the Trust Fund
         will not cause the imposition of a tax on the Trust Fund under the
         REMIC Provisions or cause either REMIC I or REMIC II of the Trust Fund
         to fail to qualify as a REMIC at any time that any Certificate is
         outstanding.

         Section 3.8 Trustee to Cooperate; Release of Mortgage Files. Upon the
payment in full of any Loan, or the receipt by the Servicer of a notification
that the payment in full will be escrowed in a manner customary for such
purposes, the Servicer will immediately notify the Trustee (and the Custodian)
by an Officer's Certificate (which Officer's Certificate shall include a
statement to the effect that all amounts received in connection with such
payment which are required to be deposited in the Custodial Account for P&I
pursuant to Section 3.2 have been or will be so deposited) and shall by such
Officer's Certificate request delivery to it of the Mortgage

                                       54

<PAGE>

File. Upon receipt of such Officer's Certificate and request, the Trustee
shall, not later than the 5th succeeding Business Day, release or cause
to be released the related Mortgage File to the Servicer. From time to time and
as appropriate for the servicing or foreclosure of any Loan, the Trustee shall,
upon written request of the Servicer and delivery to the Trustee of a trust
receipt signed by a Servicing Officer, release or cause to be released, not
later than the 5th succeeding Business Day, the related Mortgage File to the
Servicer and shall execute such documents furnished to it as shall be necessary
to the prosecution of any such proceedings. Such trust receipt shall obligate
the Servicer to return each and every document previously requested from the
Mortgage File to the Trustee when the need therefor by the Servicer no longer
exists unless the Loan shall be liquidated, in which case, upon receipt of a
certificate of a Servicing Officer similar to that hereinabove specified, the
trust receipt shall be released by the Trustee to the Servicer by delivery to a
Servicing Officer and the Trustee shall have no further responsibility with
respect to such Mortgage Files.

         Section 3.9 Servicing Compensation. The Servicer shall be entitled to
retain or, if not retained, to withdraw from the Certificate Account or the
Custodial Account for P&I as servicing compensation its Servicing Fee out of
each payment on account of interest on each Loan, subject to adjustment as
provided in Section 4.6. The Servicer shall also be entitled to payment of
unpaid Servicing Fees with respect to a delinquent Loan out of Liquidation
Proceeds with respect to such Loan, to the extent permitted by Section 3.3(b).
Servicing compensation in the form of assumption fees, late payment charges or
otherwise shall be retained by the Servicer and need not be deposited in the
Custodial Account for P&I. The Servicer shall also be entitled to additional
servicing compensation out of Liquidation Proceeds to the extent provided in
Section 3.3(b). The Servicer shall be required to pay all expenses incurred by
it in connection with its servicing activities hereunder (including maintenance
of the blanket fidelity bond and errors and omissions policy required by Section
3.5) and shall not be entitled to reimbursement therefor except as specifically
provided in Sections 3.1, 3.3, 3.5 and 3.7.

         Section 3.10 Reports to the Trustee; Custodial Account for P&I
Statements. On or before 12:00 noon (New York City time) on the second Business
Day prior to each Distribution Date, the Servicer shall deliver or cause to be
delivered to the Trustee or its designee a statement in electronic or written
form as may be agreed upon by the Servicer and the Trustee containing the
information described in Section 4.2 and such other information as may be
necessary for the Trustee to compute the amounts to be distributed to the
Certificateholders by the Trustee (the "Servicer's Section 3.10 Report"). Not
later than 25 days after each Distribution Date, the Servicer shall forward or
cause to be forwarded to the Trustee a statement, certified by a Servicing
Officer, setting forth the status of the Custodial Account for P&I as of the
close of business on the related Distribution Date, stating that all
distributions from the Custodial Account for P&I required to be made by this
Agreement have been made for the period covered by such statement (or if any
required distribution has not been made, specifying the nature and status
thereof) and showing, for the period covered by such statement, the aggregate of
deposits into and withdrawals from the Custodial Account for P&I for each
category of deposit specified in Section 3.2 and each category of withdrawal
specified in Section 3.3. Such statement shall also include information as to
the aggregate Principal Balance of all of the Loans as of the last day of the
calendar month immediately preceding such Distribution Date. Copies of such
statement shall be provided to any Certificateholder upon request by the
Servicer, or by the

                                       55

<PAGE>

Trustee so long as the Trustee has received the report as stipulated
above at the Servicer's expense if the Servicer shall fail to provide such
copies.

         Section 3.11 Annual Statement as to Compliance. The Servicer will
deliver to the Trustee, on or before April 30 of each year, beginning April 30,
2002, an Officer's Certificate stating as to each signer thereof, that (i) a
review of the activities of the Servicer during the preceding calendar year and
of performance under this Agreement has been made under such officer's
supervision, and (ii) to the best of such officer's knowledge, based on such
review, the Servicer has fulfilled all of 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. Copies of such statement shall be provided to each
Rating Agency and to any Certificateholder upon request by the Servicer, or by
the Trustee at the Servicer's expense.

         Section 3.12 Annual Independent Public Accountants' Servicing Report.
On or before April 30 of each year, beginning April 30, 2002, the Servicer, at
its expense, shall cause a firm of independent public accountants who are
members of the American Institute of Certified Public Accountants to furnish a
statement to the Trustee to the effect that, in connection with the firm's
examination of the financial statements as of the previous December 31 of the
Servicer's parent corporation (which shall include a limited examination of the
Servicer's financial statements), nothing came to their attention that indicated
that the Servicer was not in compliance with Section 3.02, Section 3.03, Section
3.04, Section 3.05, Section 3.11, Section 3.12 and Section 3.13 of this
Agreement, except for (i) such exceptions as such firm believes to be
immaterial, and (ii) such other exceptions as are set forth in such statement.
Copies of such statement shall be provided to Certificateholders upon request by
the Servicer, or by the Trustee at the Servicer's expense.

         Section 3.13 Access to Certain Documentation and Information Regarding
the Loans. The Servicer shall provide access to the Trustee or to its designees
at its request, and to Certificateholders which are savings and loan
associations, banks or insurance companies, the OTS, the FDIC and the
supervisory agents and examiners of the OTS and the FDIC or examiners of any
other federal or state banking or insurance regulatory authority to the
documentation regarding the Loans if so required by applicable regulations of
the OTS or other regulatory authority, such access to be afforded without charge
but only upon reasonable request and during normal business hours at the offices
of the Servicer designated by it. The Trustee or its designee may without charge
copy any document or electronic record maintained by the Servicer hereunder.

         Section 3.14 [Reserved].

         Section 3.15 Sale of Defaulted Loans and REO Properties.

         (a) The Servicer may then offer to sell to any Person any Defaulted
Loan or any REO Property or, subject to the following sentence, purchase any
such Defaulted Loan or REO Property (in each case at the Repurchase Price
therefor), but shall in any event, so offer to sell any REO Property no later
than the time determined by the Servicer to be sufficient to result in the sale
of such REO Property within the period specified in Section 3.7(c). The Servicer
shall

                                       56

<PAGE>

accept the highest bid received from any Person for any Defaulted Loan or
any REO Property in an amount at least equal to the Purchase Price therefor or,
at its option, if it has received no bid at least equal to the Purchase Price
therefor, purchase the Defaulted Loan or REO Property at the Purchase Price.

         In the absence of any such bid or purchase by the Servicer, the
Servicer shall accept the highest bid received from any Person that is
determined by the Servicer to be a fair price for such Defaulted Loan or REO
Property, if the highest bidder is a Person other than an Interested Person, or
is determined to be such a price by the Trustee, if the highest bidder is an
Interested Person. Notwithstanding anything to the contrary herein, neither the
Trustee, in its individual capacity, nor any of its Affiliates may bid for or
purchase any Defaulted Loan or any REO Property pursuant hereto.

         The Servicer shall not be obligated by either of the foregoing
paragraphs or otherwise to accept the highest bid if the Servicer determines, in
accordance with the servicing standard stated in Section 3.1, that rejection of
such bid would be in the best interests of the Certificateholders. In addition,
the Servicer may accept a lower bid if it determines, in accordance with the
servicing standard stated in Section 3.1, that acceptance of such bid would be
in the best interests of the Certificateholders (for example, if the prospective
buyer making the lower bid is more likely to perform its obligations, or the
terms offered by the prospective buyer making the lower bid are more favorable).
In the event that the Servicer determines with respect to any REO Property that
the bids being made with respect thereto are not in the best interests of the
Certificateholders and that the end of the period referred to in Section 3.7(c)
with respect to such REO Property is approaching, the Servicer shall seek an
extension of such period in the manner described in Section 3.7(c).

         (b) In determining whether any bid received from an Interested Person
represents a fair price for any Defaulted Loan or any REO Property, the Trustee
may conclusively rely on the opinion of an Independent appraiser or other expert
in real estate matters retained by the Trustee the expense of which shall be an
expense of the Trust Fund. In determining whether any bid constitutes a fair
price for any Defaulted Loan or any REO Property, the Servicer or the Trustee
(or, if applicable, such appraiser) shall take into account, and any appraiser
or other expert in real estate matters shall be instructed to take into account,
as applicable, among other factors, the period and amount of any delinquency on
the affected Defaulted Loan, the physical condition of the related Mortgaged
Property or such REO Property, the state of the local economy and the Trust
Fund's obligation to dispose of any REO Property within the time period
specified in Section 3.7(c).

         (c) The Servicer shall act on behalf of the Trust Fund in negotiating
and taking any other action reasonably necessary or appropriate in connection
with the sale of any Defaulted Loan or REO Property, including the collection of
all amounts payable in connection therewith. Any sale of a Defaulted Loan or any
REO Property shall be without recourse to, or representation or warranty by, the
Trustee, the Depositor, the Servicer or the Trust Fund (except that any contract
of sale and assignment and conveyance documents may contain customary warranties
of title, so long as the only recourse for breach thereof is to the Trust Fund),
and, if consummated in accordance with the terms of this Agreement, neither the
Servicer, the

                                       57

<PAGE>

Depositor nor the Trustee shall have any liability to the Trust
Fund or any Certificateholder with respect to the purchase price therefor
accepted by the Servicer or the Trustee.

         (d) The proceeds of any sale after deduction of the expenses of such
sale incurred in connection therewith shall be promptly deposited in the
Custodial Account for P&I in accordance with Section 3.2(b).

         Section 3.16 Delegation of Duties. In the ordinary course of business,
the Servicer or the Trustee may at any time delegate any duties hereunder to any
Person who agrees to conduct such duties in accordance with the applicable terms
of this Agreement. In case of such delegation, the Servicer or the Trustee shall
supervise, administer, monitor and oversee the activities of such Person
hereunder to insure that such Person performs such duties in accordance herewith
and shall be responsible for the acts and omissions of such Person to the same
extent as it is responsible for its own actions or omissions hereunder. Any such
delegations shall not relieve the Servicer or the Trustee of its liability and
responsibility with respect to such duties, and shall not constitute a
resignation within the meaning of Section 6.4 hereof and shall be revocable by
any successor Servicer or the Trustee.

         Section 3.17 [Reserved].

         Section 3.18 [Reserved].

         Section 3.19 Appointment of a Special Servicer. The Servicer may enter
into a special servicing agreement with an unaffiliated holder of Subordinate
Certificates or a holder of a class of securities representing interests in such
Class of Subordinate Certificates, such agreement to be (i) substantially in the
form of Exhibit R hereto or (ii) subject to each Rating Agency's acknowledgment
that the ratings of the Certificates in effect immediately prior to the entering
into of 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 Loans and may 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.

         Section 3.20 Allocation of Realized Losses. Prior to each Distribution
Date, the Servicer shall determine the amount of Realized Losses, if any, with
respect to each Loan. All Realized Losses, except for Excess Losses, will be
allocated as follows: (i) for losses allocable to principal (a) first, to the
Subordinate Certificates in reverse order of seniority until each of their Class
Principal Balances have been reduced to zero and (b) second, to the Senior
Certificates, by Pro Rata Allocation, until the Certificate Principal Balances
thereof have been reduced to zero; and (ii) for losses allocable to interest (a)
first, to the Subordinate Certificates in reverse order of seniority, in
reduction of accrued but unpaid interest thereon and then in reduction of the
Class Principal Balance of such Certificates and (b) second, to the Senior
Certificates, by Pro Rata Allocation, until the Certificate Principal Balances
thereof have been reduced to zero.

                                       58

<PAGE>

         Excess Losses shall be allocated among the Senior Certificates and the
Subordinate Certificates by Pro Rata Allocation.

         On each Distribution Date, after giving effect to the principal
distributions and allocations and reimbursement of losses as provided in this
Agreement (without regard to this paragraph), if the Aggregate Certificate
Principal Balance of all outstanding Classes of Certificates exceeds the
aggregate principal balance of the Loans, after deduction of (i) all principal
payments due on or before the Cut-Off Date in respect of each such Loan whether
or not paid and (ii) all amounts of principal in respect of each such Loan that
have been received or advanced and included in the Available Distribution
Amount, and all losses in respect of such Loans that have been allocated to the
Certificates, on such Distribution Date or prior Distribution Dates, then such
excess will be deemed a principal loss and will be allocated (i) first, to the
Subordinate Certificates in reverse order of seniority until each of their Class
Principal Balances has been reduced to zero, and (ii) second, to the Senior
Certificates, other than the Interest Only Certificates, pro rata according to
their Certificate Principal Balances or, in the case of the Accrual
Certificates, the Certificate Principal Balance of that Accrual Certificate on
the Closing Date, if lower in reduction thereof.

                    PAYMENTS TO CERTIFICATEHOLDERS; ADVANCES;
                             STATEMENTS AND REPORTS

         Section 4.1 Distributions to Certificateholders. (a) The Trustee shall
establish and maintain a separate account as set forth in Article I (the
"Certificate Account"), the purpose of which is to accept deposits from the
Servicer and to make distributions to the Certificateholders of the amounts set
forth in this Section 4.1.

         (b) On each Distribution Date, the Trustee or the Paying Agent, if any,
shall (i) withdraw from the Certificate Account the Available Distribution
Amount for such Distribution Date and shall distribute to each
Certificateholder, from the amount so withdrawn and to the extent of the
Available Distribution Amount, such Certificateholder's share (based on the
aggregate Percentage Interests represented by the Certificates of the applicable
Class held by such Certificateholder) of the amounts and in the order of
priority as set forth in the definition of "Certificate Distribution Amount",
and (ii) distribute Excess Liquidation Proceeds to the Class R
Certificateholders by wire transfer in immediately available funds for the
account of the Certificateholder, or by any other means of payment acceptable to
each Certificateholder of record on the immediately preceding Record Date (other
than as provided in Section 9.1 respecting the final distribution), as specified
by each such Certificateholder and at the address of such Holder appearing in
the Certificate Register; provided, that such distributions in (i) and (ii)
above shall be made in accordance with written statements received from the
Servicer pursuant to Section 4.2.

         (c) All reductions in the Certificate Principal Balance of a
Certificate effected by distributions of principal or allocations of Realized
Losses with respect to Loans made on any Distribution Date shall be binding upon
all Holders of such Certificate and of any Certificate issued upon the
registration of transfer or exchange therefor or in lieu thereof, whether or not

                                       59

<PAGE>

such distribution is noted on such Certificate. The final distribution of
principal of each Certificate (and the final distribution with respect to the
Class R Certificates upon termination of the Trust Fund) shall be payable in the
manner provided above only upon presentation and surrender thereof on or after
the Distribution Date therefor at the office or agency of the Trustee specified
in the notice delivered pursuant to Section 4.1(d) or Section 9.1.

         (d) Whenever, on the basis of Curtailments, Payoffs and Monthly
Payments on the Loans and Insurance Proceeds and Liquidation Proceeds received
and expected to be received during the applicable Prepayment Period, the Trustee
believes, or the Servicer has notified the Trustee that it believes, that the
entire remaining unpaid Class Principal Balance of any Class of Certificates
will become distributable on the next Distribution Date, the Trustee shall, no
later than the Determination Date of the month of such Distribution Date, mail
or cause to be mailed to each Person in whose name a Certificate to be so
retired is registered at the close of business on the Record Date, to the
Underwriters and to each Rating Agency a notice to the effect that:

               (i) it is expected that funds sufficient to make such final
         distribution will be available in the Certificate Account on such
         Distribution Date, and

               (ii) if such funds are available, (A) such final distribution
         will be payable on such Distribution Date, but only upon presentation
         and surrender of such Certificate at the office or agency of the
         Certificate Registrar maintained for such purpose (the address of which
         shall be set forth in such notice), and (B) no interest shall accrue on
         such Certificate after such Distribution Date.

         Section 4.2 Statements to Certificateholders. (a) Not later than three
(3) days prior to each Distribution Date, the Servicer shall forward to the
Trustee the Servicer's Section 3.10 Report setting forth certain information
with respect to the Loans. With each distribution from the Certificate Account
on a Distribution Date, the Trustee shall make available to each
Certificateholder, through the Trustee's Corporate Trust home page on the world
wide web which is currently located at "corporatetrust.statestreet.com", a
statement (each a "Certificateholders' Report") prepared by the Servicer based
on the information set forth in the Servicer's Section 3.10 Report, setting
forth, to the extent applicable, the amount of the distribution payable to the
applicable Class that represents principal, separately identifying the aggregate
amount of any Principal prepayments included in such distribution, and the
amount that represents interest, and the applicable Class Principal Balance
after giving effect to such distribution.

         In addition, not later than each Distribution Date, the Trustee shall
forward to such Certificateholder and the Depositor an additional report which
sets forth with respect to the Loans:

               (i) The number and aggregate Principal Balance of the Loans
         delinquent one, two and three months or more;

               (ii) The (A) number and aggregate Principal Balance of Loans with
         respect to which foreclosure proceedings have been initiated, and (B)
         the number and aggregate book value of Mortgaged Properties acquired
         through foreclosure, deed in lieu of

                                       60

         security interest in the Loans;

               (iii) The aggregate Principal Balance of the Loans as of the
         close of business on the last day of the related Prepayment Period;

               (iv) The amount of the Servicing Fee retained or withdrawn by the
         Servicer from the Certificate Account and the amount of any Excess
         Liquidation Proceeds received by the Servicer during the related
         Prepayment Period;

               (v) The amount of Special Hazard Coverage available to the Senior
         Certificates remaining as of the close of business on the applicable
         Determination Date;

               (vi) The amount of Bankruptcy Coverage available to the Senior

         Certificates remaining as of the close of business on the applicable
         Determination Date;

               (viii) The amount of Realized Losses allocable to the related
         Certificates on the related Distribution Date and the cumulative amount
         of Realized Losses incurred allocated to such Certificates since the
         Cut-Off Date; and

               (ix) The weighted average Pass-Through Rates as of the first day
         of the month immediately preceding the month of the Distribution Date.

         Upon request by any Certificateholder, the Servicer, as soon as
reasonably practicable, shall provide the requesting Certificateholder with such
information as is necessary and appropriate, in Servicer's sole discretion, for
purposes of satisfying applicable reporting requirements under Rule 144A of the
Securities Act.

         The Servicer may make available any reports, statements or other
information to Certificateholders through the Servicer's home page on the world
wide web. Such web page is located at "www.wamumsc.com" and information is
available by clicking on "Investor Information."

         The Trustee may make available any reports, statements or other
information to Certificateholders through the Trustee's home page on the world
wide web. Such web page is currently located at
"corporatetrust.statestreet.com".

         (b) Upon request to the Trustee by any Certificateholder who is a
Holder thereof at the time of making such request (an "Eligible
Certificateholder"), the Servicer shall provide in electronic format loan by
loan data with respect to the payment experience of the Loans containing at
least the fields of information listed on Exhibit E hereto (based on information
provided by the Servicer). In addition, upon the written request of any Eligible
Certificateholder, the Trustee shall provide similar loan by loan data with
respect to any prior monthly remittance report to the Certificateholders
pursuant to this Agreement (as and when such information

                                       61

<PAGE>

becomes available). The expense of providing any tape or disk pursuant to this
subsection shall be an expense of the Eligible Certificateholder.

         Section 4.3 Advances by the Servicer; Distribution Reports to the
Trustee. To the extent described below, the Servicer is obligated to advance its
own funds to the Certificate Account to cover any shortfall between (i) payments
scheduled to be received in respect of Loans serviced by such Servicer, and (ii)
the amounts actually deposited in the Certificate Account on account of such
payments. The Servicer's obligation to make any Advance or Advances described in
this Section 4.3 is effective only to the extent that such Advance is, in the
good faith judgment of the Servicer, reimbursable from Insurance Proceeds or
Liquidation Proceeds of the related Loans or recoverable as late Monthly
Payments with respect to the related Loans or otherwise.

         Prior to the close of business on the second Business Day prior to each
Distribution Date, the Servicer shall determine whether or not it will make an
Advance on the next Withdrawal Date and shall furnish a statement to the
Trustee, the Paying Agent, if any, and to any Certificateholder requesting the
same, setting forth the aggregate amount to be distributed on the next
succeeding Distribution Date on account of principal and interest in respect of
the Loans, stated separately. In the event that full scheduled amounts of
principal and interest in respect of the related Loans shall not have been
received by or on behalf of the Servicer prior to the Determination Date
preceding such Distribution Date and the Servicer shall have determined that an
Advance shall be made in accordance with this Section 4.3, the Servicer shall so
specify and shall specify the aggregate amount of such Advance.

         In the event that the Servicer shall be required to make an Advance, it
shall on the Business Day prior to the Distribution Date either (i) deposit in
the Certificate Account an amount equal to such Advance, (ii) direct the Trustee
to make an appropriate entry in the records of the Certificate Account, or the
Servicer shall make an appropriate entry in the records for the Custodial
Account for P&I, that funds in such account being held for future distribution
or withdrawal have been, as permitted by this Section 4.3, used by such Servicer
to make such Advance, or (iii) make advances in the form of any combination of
(i) and (ii) aggregating the amount of such Advance. Any funds being held for
future distribution to Certificateholders and so used shall be replaced by the
Servicer by deposit in the Certificate Account on any future Distribution Date
to the extent that funds in the Certificate Account on such Distribution Date
with respect to the related Loans shall be less than payments to
Certificateholders required to be made on such date with respect to such Loans.

         The Servicer shall be entitled to reimbursement for any Advance as
provided in Section 3.3 of this Agreement.

         Prior to 5:00 P.M. New York City time on the second Business Day prior
to each Distribution Date, the Servicer shall provide the Trustee with a
statement regarding the amount of principal and interest, the Residual
Distribution Amount and the Excess Liquidation Proceeds to be distributed to
each Class of Certificates on such Distribution Date (such amounts to be
determined in accordance with the definition of "Certificate Distribution
Amount", Section 4.1 hereof and other related definitions set forth in Article I
hereof).

                                       62
<PAGE>

         Section 4.4 Nonrecoverable Advances. Any Advance previously made by or
on behalf of the Servicer with respect to a Loan that the Servicer shall
determine in its good faith judgment not to be ultimately recoverable from
Insurance Proceeds or Liquidation Proceeds or otherwise with respect to such
Loan or recoverable as late Monthly Payments with respect to such Loan shall be
a Nonrecoverable Advance. The determination by the Servicer that it has made a
Nonrecoverable Advance or that any advance would constitute a Nonrecoverable
Advance, shall be evidenced by an Officer's Certificate of the Servicer
delivered to the Trustee on the Withdrawal Date and detailing the reasons for
such determination. Notwithstanding any other provision of this Agreement, any
insurance policy relating to the Loans, or any other agreement relating to the
Loans to which the Depositor or the Servicer is a party, (a) the Servicer shall
not be obligated to, and shall not, make any advance that, after reasonable
inquiry and in its sole discretion, it determines would be a Nonrecoverable
Advance, and (b) the Servicer shall be entitled to reimbursement for any
Nonrecoverable Advance as provided in Section 3.3 of this Agreement.

         Section 4.5 Foreclosure Reports. Each year beginning in 2002 the
Servicer shall make any reports of foreclosures and abandonments of any
Mortgaged Property required by Section 6050J of the Code. In order to facilitate
this reporting process, the Servicer, on or before February 28th of each year,
commencing with 2002, shall provide to the Internal Revenue Service and the
Trustee reports relating to each instance occurring during the previous calendar
year in which the Servicer (i) on behalf of the Trustee acquires an interest in
a Mortgaged Property through foreclosure or other comparable conversion in full
or partial satisfaction of a Loan, or (ii) knows or has reason to know that a
Mortgaged Property has been abandoned. The reports from the Servicer shall be in
form and substance sufficient to meet the reporting requirements imposed by such
Section 6050J.

         Section 4.6 Adjustment of Servicing Fees with Respect to Payoffs. The
aggregate amount of the Servicing Fee subject to retention from deposit into or
withdrawal from the Certificate Account by the Servicer, in any month of
distribution shall be decreased by any Compensating Interest due and owing with
respect to any Loan with respect to which a Payoff has occurred in the related
Prepayment Period. The Servicer shall include the amount of any such
Compensating Interest with the deposits into the Certificate Account on the
related Withdrawal Date. Notwithstanding the foregoing, the amount by which the
Servicing Fee may be reduced with respect to the related Prepayment Period
pursuant to this Section 4.6 shall not exceed an amount greater than the amount
described in clause (i) of the definition of Compensating Interest for all Loans
as to which Payoffs have occurred and the rights of the Certificateholders to
such portion of the Servicing Fee shall not be cumulative.

         Section 4.7 Prohibited Transactions Taxes and Other Taxes. In the event
that any tax (including a tax on "prohibited transactions" as defined in Section
860F(a)(2) of the Code and including any and all interest, penalties, fines and
additions to tax, as well as any and all reasonable counsel fees and
out-of-pocket expenses incurred in contesting the imposition of such tax) is
imposed on the Trust Fund and is not otherwise paid pursuant to Section 4.7(b)
hereof, the Servicer shall pay such taxes when and as the same shall be due and
payable (but such obligation shall not prevent the Servicer, the Trustee or any
other appropriate Person from contesting any such tax in appropriate proceedings
and shall not prevent the Servicer from withholding payment of such tax, if
permitted by law, pending the outcome of such proceedings); provided, that the

                                       63

<PAGE>

Servicer shall be entitled to be indemnified for any such taxes (excluding taxes
referred to in Section 4.7(b)) to the extent set forth in Section 6.3 hereof so
long as the Servicer's failure to exercise reasonable care with respect to the
performance of its duties hereunder was not the primary cause of the imposition
of such taxes. If the Servicer is indemnified for such taxes pursuant to this
Section 4.7(a), such amount shall be first charged against amounts otherwise
distributable to the Holders of Component R-1 of the Class R Certificates (or,
if the tax relates to REMIC II, Component R-2 of the Class R Certificates) on a
pro rata basis, then against amounts otherwise distributable with respect to the
REMIC I Regular Interests (or, if the tax relates to REMIC II, to the Holders of
the REMIC II Certificates) on a pro rata basis. The Trustee is hereby authorized
to retain from amounts otherwise distributable to the Certificateholders
sufficient funds to reimburse the Servicer for the payment of such tax for which
the Servicer is entitled to indemnification.

         Section 4.8 Tax Administration. The Servicer is hereby appointed as
attorney-in-fact and agent for the initial Tax Matters Person.

         Section 4.9 Equal Status of Servicing Fee. The right of the Servicer to
receive its Servicing Fee will be equal and not subordinate to the right of the
Certificateholders to receive principal and interest payments based on their
interests as provided herein. The Servicer's Servicing Fee may be collected from
Monthly Payments as received pursuant to Section 3.2 without deposit into the
Certificate Account, whereas the Certificateholders' distributions shall be made
on a delayed basis as set forth in the terms of the Certificates.

         Section 4.10 Appointment of Paying Agent. The Trustee may appoint an
Eligible Institution to act as a paying agent (the "Paying Agent") in order to
delegate to such Eligible Institution any of its duties under this Agreement to
administer the issuance, transfer and exchange of the Certificates, administer
payments to Certificateholders or prepare information related to the
Certificates; provided, that the Trustee shall remain primarily responsible for
any duties so delegated; provided, further, that the Trustee shall receive no
additional compensation in connection with such appointment and delegation.

         Initially, the Trustee will be the Paying Agent. If the Trustee ceases
to serve as Paying Agent, the Trustee shall send written notice to all
Certificateholders (i) indicating that it is no longer serving in such capacity
and (ii) setting forth its replacement, if any, appointed pursuant to this
Section 4.10.

                                   ARTICLE V

officers of the Trustee. Certificates bearing the manual or facsimile
signatures of individuals who were at the time of execution the proper officers
of the Trustee shall bind the Trust Fund, notwithstanding that such individuals
or any of them have ceased to hold such offices prior to the authentication and
delivery of such Certificates or did not hold such offices at the date of such
Certificates. No Certificate shall be entitled to any benefit under this
Agreement, or be valid for any purpose, unless there appears on such Certificate
a certificate of authentication substantially in the form provided for herein
executed by the Trustee or any Authenticating Agent by manual signature, and
such certificate 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 authentication.

         (b) The following definitions apply for purposes of this Section 5.1:
"Disqualified Organization" means any Person which is not a Permitted

               change in its status as a Permitted Transferee.

                     (B) In connection with any proposed Transfer of any
               Ownership Interest in a Residual Certificate to a U.S. Person,

               Agreement from any other Person to whom such Person attempts to
               transfer its Ownership Interest and to provide a certificate to
               the Trustee or the Certificate Registrar if not the same Person
               as the Trustee in the form attached hereto as Exhibit J; (ii) to
               obtain the express written consent of the Depositor prior to any
               transfer of such Ownership Interest, which consent may be
               withheld in the Depositor's sole discretion; and (iii) to provide
               a certificate to the Trustee or the Certificate Registrar if not
               the same Person as the Trustee in the form attached hereto as
               Exhibit I.

               (ii) The Trustee or the Certificate Registrar if not the same
         Person as the Trustee shall register the Transfer of any Residual
         Certificate only if it shall have received the Transferee Affidavit and
         Agreement, a certificate of the Holder requesting such transfer in the
         form attached hereto as Exhibit J and all of such other documents as
         shall have been reasonably required by the Trustee or the Certificate
         Registrar if not the same Person as the Trustee as a condition to such
         registration.

               (iii) (A) If any Disqualified Organization shall become a Holder
         of a Residual Certificate, then the last preceding Permitted Transferee
         shall be restored, to the extent permitted by law, to all rights and
         obligations as Holder thereof retroactive to the date of registration
         of such Transfer of such Residual Certificate. If any Non-U.S. Person
         shall become a Holder of a Residual Certificate, then the last
         preceding Holder which is a U.S. Person shall be restored, to the
         extent permitted by law, to all rights and obligations as

                                       66

<PAGE>

         Holder thereof retroactive to the date of registration of the
         Transfer to such Non-U.S. Person of such Residual Certificate. If a
         transfer of a Residual Certificate is disregarded pursuant to the
         provisions of Treasury Regulations Section 1.860E-1 or Section
         1.860G-3, then the last preceding Permitted Transferee shall be
         restored, to the extent permitted by law, to all rights and obligations
         as Holder thereof retroactive to the date of registration of such
         Transfer of such Residual Certificate. The Trustee, the Servicer, the
         Certificate Registrar and the Paying Agent 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 5.1(c) or for
         making any payments due on such Certificate to the Holder thereof or
         for taking any other action with respect to such Holder under the
         provisions of this Agreement.

                     (B) If any purported Transferee shall become a Holder of a
               Residual Certificate in violation of the restrictions in this
               Section 5.1(c) and to the extent that the retroactive restoration
               of the rights of the Holder of such Residual Certificate as
               described in clause (iii)(A) above shall be invalid, illegal or
               unenforceable, then the Depositor shall have the right, without
               notice to the Holder or any prior Holder of such Residual
               Certificate, to sell such Residual Certificate to a purchaser
               selected by the Depositor on such terms as the Depositor may
               choose. Such purported Transferee shall promptly endorse and
               deliver such Residual Certificate in accordance with the
               instructions of the Depositor. Such purchaser may be the
               Depositor itself or any affiliate of the Depositor. The proceeds
               of such sale, net of the commissions (which may include
               commissions payable to the Depositor or its affiliates), expenses
               and taxes due, if any, shall be remitted by the Depositor to such
               purported Transferee. The terms and conditions of any sale under
               this clause (iii)(B) shall be determined in the sole discretion
               of the Depositor, and the Depositor shall not be liable to any
               Person having an Ownership Interest in a Residual Certificate as
               a result of its exercise of such discretion.

               (iv) The Depositor, on behalf of the Trustee, shall make
         available, upon written request from the Trustee, or the Servicer all
         information necessary to compute any tax imposed (A) as a result of the
         Transfer of an Ownership Interest in a Residual Certificate to any
         Person who is not a Permitted Transferee, including the information
         regarding "excess inclusions" of such Residual Certificate required to
         be provided to the Internal Revenue Service and certain Persons as
         described in Treasury Regulation Section 1.860D-1(b)(5), and (B) as a
         result of any regulated investment company, real estate investment
         trust, common trust fund, partnership, trust, estate or organizations
         described in Section 1381 of the Code having as among its record
         holders at any time any Person who is not a Permitted Transferee.
         Reasonable compensation for providing such information may be required
         by the Depositor from such Person.

               (v) The provisions of this Section 5.1 set forth prior to this
         Section 5.1(c)(v) may be modified, added to or eliminated, provided,
         that there shall have been delivered to the Trustee and the Servicer
         the following:

<PAGE>

                     (A) written notification from each Rating Agency to the
               effect that the modification, addition to or elimination of such
               provisions will not cause such Rating Agency to downgrade its
               then-current Ratings of the Certificates; and

                     (B) an Opinion of Counsel, in form and substance
               satisfactory to the Depositor (as evidenced by a certificate of
               the Depositor), to the effect that such modification, addition to
               or absence of such provisions will not cause the Trust Fund to
               cease to qualify as a REMIC and will not create a risk that (1)
               the Trust Fund may be subject to an entity-level tax caused by
               the Transfer of any Residual Certificate to a Person which is not
               a Permitted Transferee or (2) a Certificateholder or another
               Person will be subject to a REMIC-related tax caused by the
               Transfer of a Residual Certificate to a Person which is not a
               Permitted Transferee.

               (vi) The following legend shall appear on all Residual
         Certificates:

Securities Act, as follows: In the event that a transfer is to be made
in reliance upon an exemption from the Securities Act, the Trustee or the
Certificate Registrar, if not the same Person as the Trustee, shall require, in
order to assure compliance with the Securities Act, that the Certificateholder
desiring to effect such transfer certify to the Trustee and the Certificate
Registrar in writing, in substantially the form attached hereto as Exhibit F,
the facts surrounding the transfer, with such modifications to such Exhibit F as
may be appropriate to reflect the actual facts of the proposed transfer, and
that the Certificateholder's proposed transferee certify to the Trustee and the
Certificate Registrar in writing, in substantially the form attached hereto as
Exhibit G, the facts surrounding the transfer, with such modifications to such
Exhibit G as may be appropriate to reflect the actual facts of the proposed
transfer. If such certificate of the proposed transferee does not contain
substantially the substance of Exhibit G, the Trustee or the Certificate
Registrar, if not the same Person as the Trustee, shall require an Opinion of
Counsel satisfactory to it that such transfer may be made without registration,
which Opinion of Counsel shall not be obtained at the expense of the Trustee,
the Servicer, the Certificate Registrar, the Trust Fund or the Depositor. Such
Opinion of Counsel shall allow for the forwarding, and the Trustee shall
forward, a copy thereof to each Rating Agency. Notwithstanding the foregoing,
any Class of Junior Subordinate Certificates may be transferred, sold, pledged
or otherwise disposed of in accordance with the requirements set forth in
Section 5.1(f).

         (f) Transfers of the Junior Subordinate Certificates may be made in
accordance with this Section 5.1(f). To effectuate a Certificate transfer in
accordance with this Section 5.1(f), the proposed transferee of such Certificate
must provide the Trustee, the Certificate Registrar and the Depositor with an
investment letter substantially in the form of Exhibit L attached hereto, which
investment letter shall not be an expense of the Trustee, the Servicer, the
Certificate Registrar or the Depositor, and which investment letter states that,
among other things, such transferee (i) is a "qualified institutional buyer" as

"qualified institutional buyers" as defined under Rule 144A, and (ii) is aware
that the proposed transferor intends to rely on the exemption from registration
requirements under the Securities Act provided by Rule 144A. Notwithstanding the
foregoing, the proposed transferee of such Certificate shall not be required to
provide the Trustee, the Certificate Registrar or the Depositor with Annex 1 or
Annex 2 to the form of Exhibit L attached hereto if the Depositor so consents
prior to each such transfer. Such transfers shall be deemed to have complied
with the requirements of this Section 5.1(f). The Holder of a Certificate
desiring to effect such transfer does hereby agree to indemnify the Trustee, the
Servicer, the Depositor, and the Certificate Registrar against any liability
that may result if transfer is not made in accordance with this Agreement.

         (g) None of the Trustee, the Servicer, the Certificate Registrar or the
Paying Agent shall have any liability to the Trust Fund arising from a
registration or transfer of a Certificate in reliance upon a certification,
Officer's Certificate, affidavit, ruling or Opinion of Counsel described in this
Section 5.1.

Certificates authenticated and delivered upon registration of transfer of, or in

                                       70

aggregate principal amount shall be allocated among one or more Classes having
designations, types of interests, initial per annum Remittance Rates, initial
Class Principal Balances and last scheduled Distribution Dates as specified in

of each Class of Certificates of which the Class Principal Balance equals zero
as of the Cut-Off Date that may be authenticated and delivered under this
Agreement is limited to 100%. Certificates shall be issued in Authorized
Denominations.

         Section 5.3 Registration of Transfer and Exchange of Certificates. The
Trustee shall cause to be maintained at one of its offices or at its designated
Certificate Registrar, a Certificate Register in which there shall be recorded
the name and address of each Certificateholder. Subject to such reasonable rules
and regulations as the Trustee may prescribe, the Certificate Register shall be
amended from time to time by the Trustee or its agent to reflect notice of any
changes received by the Trustee or its agent pursuant to Section 10.5. The
Trustee hereby appoints itself as the initial Certificate Registrar. The Trustee
may appoint an Eligible Institution to act as its agent in order to delegate to
such Eligible Institution its duties as Certificate Registrar under this
Agreement.

         Upon surrender for registration of transfer of any Certificate to the
Trustee at its Corporate Trust Office or at the office of State Street Bank and
Trust Company, N.A., 61 Broadway, New York, New York 10006, or such other
address or agency as may hereafter be provided to the Servicer in writing by the
Trustee, the Trustee shall execute, and the Trustee or any Authenticating Agent
shall authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Certificates of Authorized Denominations of like
Percentage Interest. At the option of the Certificateholders, Certificates may
be exchanged for other Certificates in Authorized Denominations of like
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, or any Authenticating
Agent, shall authenticate and deliver, the Certificates which the
Certificateholder making the exchange is entitled to receive. Every Certificate
presented or surrendered for transfer shall (if so required by the Trustee or
any Authenticating Agent) be duly endorsed by, or be accompanied by a written
instrument of transfer in form satisfactory to the Trustee or any Authenticating
Agent and duly executed by, the Holder thereof or such Holder's attorney duly
authorized in writing.

         A reasonable service charge may be made for any such exchange or
transfer of Certificates, and the Trustee or an Authenticating Agent may require
payment of a sum sufficient to cover any tax or governmental charge that may be
imposed in connection with any exchange or transfer of Certificates.

         All Certificates surrendered for exchange or transfer shall be canceled
by the Trustee or any Authenticating Agent.

         Section 5.4 Mutilated, Destroyed, Lost or Stolen Certificates. If (i)
any mutilated Certificate is surrendered to the Trustee or any Authenticating
Agent, or (ii) the Trustee or any Authenticating Agent receives evidence to
their satisfaction of the destruction, loss or theft of any Certificate, and
there is delivered to the Trustee or any Authenticating Agent such security or

                                       71

<PAGE>

indemnity as may be required by them to save each of them harmless, then, in the
absence of notice to the Trustee or any Authenticating Agent that such
Certificate has been acquired by a bona fide purchaser, the Trustee shall
execute and the Trustee or any Authenticating Agent shall authenticate and
deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or
stolen Certificate, a new Certificate of like Percentage Interest. Upon the
issuance of any new Certificate under this Section 5.4, the Trustee or any
Authenticating Agent 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 or any
Authenticating Agent) connected therewith. Any replacement Certificate issued
pursuant to this Section 5.4 shall constitute complete and indefeasible evidence
of ownership in the Trust Fund, as if originally issued, whether or not the lost
or stolen Certificate shall be found at any time.

         Section 5.5 Persons Deemed Owners. The Depositor, the Servicer, the
Trustee and any agent of any of them 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 4.1 and for all other purposes
whatsoever, and neither the Depositor, the Servicer, the Trustee, the
Certificate Registrar nor any agent of the Depositor, the Servicer or the
Trustee shall be affected by notice to the contrary.

         Section 5.6 Temporary Certificates. Upon the initial issuance of the
Certificates, the Trustee may execute, and the Trustee or any Authenticating
Agent shall authenticate and deliver, temporary Certificates which are printed,
lithographed, typewritten or otherwise produced, in any Authorized Denomination,
of the tenor of the definitive Certificates in lieu of which they are issued and
with such variations in form from the forms of the Certificates set forth as
Exhibits A and B hereto as the Trustee's officers executing such Certificates
may determine, as evidenced by their execution of the Certificates.
Notwithstanding the foregoing, the Certificates may remain in the form set forth
in this Section.

         If temporary Certificates are issued, the Trustee shall cause
definitive Certificates to be prepared within ten Business Days of the Closing
Date or as soon as practicable thereafter. After preparation of definitive
Certificates, the temporary Certificates shall be exchangeable for definitive
Certificates upon surrender of the temporary Certificates at the office or
agency of the Trustee to be maintained as provided in Section 5.10 hereof,
without charge to the Holder. Any tax or governmental charge that may be imposed
in connection with any such exchange shall be borne by the Depositor. Upon
surrender for cancellation of any one or more temporary Certificates, the
Trustee shall execute and the Trustee or any Authenticating Agent shall
authenticate and deliver in exchange therefor a like principal amount of
definitive Certificates of Authorized Denominations. Until so exchanged, the
temporary Certificates shall in all respects be entitled to the same benefits
under this Agreement as definitive Certificates.

         Section 5.7 Book-Entry for Book-Entry Certificates. Notwithstanding the
foregoing, the Book-Entry Certificates, upon original issuance, shall be issued
in the form of one or more typewritten Certificates of Authorized Denomination
representing the Book-Entry Certificates, to be delivered to DTC, the initial
Clearing Agency, by, or on behalf of, the Depositor. The Book-Entry Certificates
shall initially be registered on the Certificate Register in the name of Cede &
Co., the nominee of DTC, as the initial Clearing Agency, and no Beneficial
Holder shall receive a definitive certificate representing such Beneficial
Holder's interest in any Class of Book-Entry

                                       72

Certificate, except as provided above and in Section 5.9. Each Book-Entry
Certificate shall bear the following legend:

                  Unless this Certificate is presented by an authorized
         representative of The Depository Trust Company, a New York corporation
         ("DTC"), to the Trustee or its agent for registration of transfer,
         exchange, or payment, and any Certificate issued is registered in the
         name of Cede & Co. or such other name as is requested by an authorized
         representative of DTC (and any payment is made to Cede & Co. or to such
         other entity as is requested by an authorized representative of DTC),
         ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR
         TO ANY PERSON IS WRONGFUL inasmuch as the registered owner hereof, Cede
         & Co., has an interest herein.

Unless and until definitive, fully registered Book-Entry Certificates (the
"Definitive Certificates") have been issued to the Beneficial Holders pursuant
to Section 5.9:

               (a) the provisions of this Section 5.7 shall be in full force and
         effect with respect to the Book-Entry Certificates;

               (b) the Trustee may deal with the Clearing Agency for all
         purposes with respect to the Book-Entry Certificates (including the
         making of distributions on the Book-Entry Certificates) as the sole
         Certificateholder;

               (c) to the extent that the provisions of this Section 5.7
         conflict with any other provisions of this Agreement, the provisions of
         this Section 5.7 shall control; and

               (d) the rights of the Beneficial Holders shall be exercised only
         through the Clearing Agency and the DTC Participants and shall be
         limited to those established by law and agreements between such
         Beneficial Holders and the Clearing Agency and/or the DTC Participants.
         Pursuant to the Depositary Agreement, unless and until Definitive
         Certificates are issued pursuant to Section 5.9, the initial Clearing
         Agency will make book-entry transfers among the DTC Participants and
         receive and transmit distributions of principal and interest on the
         related Class of Book-Entry Certificates to such DTC Participants.

         For purposes of any provision of this Agreement requiring or permitting
actions with the consent of, or at the direction of, Holders of Book-Entry
Certificates evidencing a specified Percentage Interest, such direction or
consent may be given by the Clearing Agency at the direction of Beneficial
Holders owning Book-Entry Certificates evidencing the requisite Percentage
Interest represented by the Book-Entry Certificates. The Clearing Agency may
take conflicting actions with respect to the Book-Entry Certificates to the
extent that such actions are taken on behalf of the Beneficial Holders.

         Section 5.8 Notices to Clearing Agency. Whenever notice or other
communication to the Certificateholders is required under this Agreement, unless
and until Definitive Certificates shall have been issued to the related
Certificateholders pursuant to Section 5.9, the Trustee shall give all such
notices and communications specified herein to be given to Holders of the Book-

                                       73

<PAGE>

Entry Certificates to the Clearing Agency which shall give such notices and
communications to the related DTC Participants in accordance with its applicable
rules, regulations and procedures.

         Section 5.9 Definitive Certificates. If (a) the Clearing Agency
notifies the Trustee that it is no longer willing or able to discharge properly
its responsibilities under the Depositary Agreement with respect to the
Book-Entry Certificates and the Trustee 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 with respect to the Book-Entry
Certificates through the Clearing Agency or (c) after the occurrence of an Event
of Default, Certificateholders holding Book-Entry Certificates evidencing
Percentage Interests aggregating not less than 66% of the aggregate Class
Principal Balance of such Certificates advise the Trustee and the Clearing
Agency through DTC Participants in writing that the continuation of a book-entry
system with respect to the Book-Entry Certificates through the Clearing Agency
is no longer in the best interests of the Certificateholders with respect to
such Certificates, the Trustee shall notify or cause to be notified all
Certificateholders of Book-Entry Certificates of the occurrence of any such
event and of the availability of Definitive Certificates. Upon surrender to the
Trustee of the Book-Entry Certificates by the Clearing Agency, accompanied by
registration instructions from the Clearing Agency for registration, the Trustee
shall execute and the Trustee or any Authenticating Agent shall authenticate and
deliver the Definitive Certificates. Neither the Depositor, the Authenticating
Agent nor the Trustee shall be liable for any delay in delivery of such
instructions and may conclusively rely on, and shall be protected in relying on,
such instructions. Upon the issuance of Definitive Certificates for all of the
Certificates all references herein to obligations imposed upon or to be
performed by the Clearing Agency shall be deemed to be imposed upon and
performed by the Trustee, and the Trustee, the Certificate Registrar and the
Paying Agent shall recognize the Holders of Definitive Certificates as
Certificateholders hereunder.

         Section 5.10 Office for Transfer of Certificates. The Trustee shall
maintain in New York, New York, an office or agency where Certificates may be
surrendered for registration of transfer or exchange. State Street Bank and
Trust Company, N.A., 61 Broadway, New York, New York 10006, Attn: Corporate
Trust Window, is initially designated for said purposes. The Trustee will give
prompt written notice to the Certificateholders of any change in such location
of any such office or agency.

                                   ARTICLE VI

                         THE DEPOSITOR AND THE SERVICER

         Section 6.1 Liability 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 imposed by this Agreement and undertaken
hereunder by the Depositor and the Servicer herein.

         Section 6.2 Merger or Consolidation of the Depositor or the Servicer.
Subject to the following paragraph, the Depositor and the Servicer each will
keep in full effect its existence, rights and franchises as corporations, each
under the laws of the jurisdiction of its incorporation, and will obtain and
preserve its qualification to do business as a foreign corporation in each
jurisdiction in which such qualification is or shall be necessary to protect the
validity and

                                       74

<PAGE>

enforceability of this Agreement, the Certificates or any of the Loans
and to perform its respective duties under this Agreement.

         The Depositor or the Servicer may be merged or consolidated with or
into any Person, or transfer all or substantially all of its assets to any
Person, in which case any Person resulting from any merger or consolidation to
which the Depositor or Servicer shall be a party, or any Person succeeding to
the business of the Depositor or Servicer, shall be the successor of the
Depositor or Servicer 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.

         Section 6.3 Limitation on Liability of the Servicer and Others. Neither
the Servicer nor any of the directors, officers, employees or agents of the
Servicer shall be under any liability to the Trust Fund 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 any director, officer,
employee or agent of the Servicer 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 any director, officer, employee or agent of
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 Servicer and any director, officer, employee or agent of the
Servicer shall be indemnified by the Trust Fund 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, in the case of the Servicer and any director, officer, employee or
agent of the Servicer, 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. The Servicer shall not be under
any obligation to appear in, prosecute or defend any legal action which is not
incidental to its duties to service the Loans in accordance with this Agreement
and which in its opinion may involve it in any expense or liability; provided,
however, that the Servicer may in its discretion undertake any such action which
it may deem necessary or desirable in respect of 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 Fund, and the Servicer shall be entitled to be reimbursed therefor out of
the Custodial Account for P&I as provided by Section 3.3.

         Section 6.4 Servicer Not to Resign. The Servicer shall not resign from
the 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 the Servicer shall be evidenced by
an Opinion of Counsel to such effect delivered to the Trustee. The Servicer
shall notify each Rating Agency of any such resignation. No such resignation
shall become effective until a successor servicer shall have assumed the
Servicer's responsibilities and obligations in accordance with Section 7.5
hereof.

         Section 6.5 Trustee Access The Servicer shall afford the Depositor and
the Trustee, upon reasonable notice, during normal business hours access to all
records maintained by the Servicer, in respect of its rights and obligations
hereunder and access to such of its officers as are

                                       75

<PAGE>

responsible for such obligations. Upon reasonable request, the Servicer, shall
furnish the Depositor and the Trustee with its most recent
financial statements (or, for so long as Washington Mutual Mortgage Securities
Corp. is Servicer hereunder, the most recent consolidated financial statements
of Washington Mutual, Inc., or the entity with whose financial statements the
financial statements of the Servicer are consolidated) and such other
information as it possesses, and which it is not prohibited by law or, to the
extent applicable, binding obligations to third parties with respect to
confidentiality from disclosing, regarding its business, affairs, property and
condition, financial or otherwise.

                                  ARTICLE VII

                                     DEFAULT

         Section 7.1 Events of Default. In case one or more of the following
Events of Default by the Servicer shall occur and be continuing, that is to say:

               (i) any failure by the Servicer to distribute or cause to be
         distributed to the Trustee or its delegate on the Withdrawal Date any
         payment required to be made to the Trustee under the terms of this
         Agreement which continues unremedied for a period of five days after
         the date upon which written notice of such failure, requiring the same
         to be remedied, shall have been given to the Servicer by the Trustee or
         to the Servicer and the Trustee by the Holders of Certificates
         evidencing Percentage Interests aggregating not less than 25% of the
         Trust Fund or 51% of the aggregate Percentage Interests of any Class of
         Certificates;

               (ii) any failure on the part of the Servicer duly to observe or
         perform in any material respect any other of the covenants or
         agreements on the part of the Servicer in the Certificates or in this
         Agreement which continues unremedied for a period of 60 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 to
         the Servicer and the Trustee by the Holders of Certificates evidencing,
         in aggregate, not less than 25% of the Trust Fund or 51% of the
         aggregate Percentage Interests of any Class of Certificates;

               (iii) a decree or order of a court or agency or supervisory
         authority having jurisdiction in the premises for the appointment of a
         conservator or receiver or liquidator in any insolvency, readjustment
         of debt, marshaling of assets and liabilities or similar proceedings,
         or for the winding-up or liquidation of its affairs, shall have been
         entered against the Servicer and such decree or order shall have
         remained in force undischarged or unstayed for a period of 60 days;

               (iv) the Servicer shall consent to the appointment of a
         conservator or receiver or liquidator or liquidating committee in any
         insolvency, readjustment of debt marshaling of assets and liabilities,
         voluntary liquidation or similar proceedings of or relating to the
         Servicer or of or relating to all or substantially all of its property;

               (v) 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

                                       76

<PAGE>

         reorganization statute, make an assignment for the benefit of its
         creditors or voluntarily suspend payment of its obligations; or

               (vi) any failure of the Servicer to make any Advance required to
         be made from its own funds pursuant to Section 4.3 which continues
         unremedied for a period of one Business Day after the date upon which
         such Advance was to have been made;

then, if an Event of Default described in clauses (i)-(v) of this Section 7.1
shall occur, and in each and every such case, subject to applicable law, so long
as an Event of Default shall not have been remedied, either the Trustee or the
Holders of Certificates evidencing, in aggregate, not less than 25% of the Trust
Fund or 51% of the aggregate Percentage Interests of any Class of Certificates
by notice in writing to the Servicer (and to the Trustee if given by the
Certificateholders) may terminate all of the rights and obligations of the
Servicer under this Agreement, but without prejudice to any rights it may have
to reimbursement of expenses, Advances and other advances of its own funds as
Servicer to the extent permitted by this Agreement, other than the Depositor's
(or its successors') obligation to repurchase any Loans pursuant to Section 2.2
or 2.3 shall survive any such termination. If an Event of Default described in
clause (vi) hereof shall occur, the Trustee shall, by notice in writing to the
Servicer, which shall be telecopied to the Servicer, immediately terminate all
of the rights and obligations of the Servicer, under this Agreement and in and
to the Loans and the proceeds thereof. 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 Loans or otherwise,
shall pass to and be vested in the Trustee pursuant to and under this Section
7.1 (subject to the provisions of Section 7.5); 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 or assignment of the Loans and related
documents or otherwise at the expense of the Servicer. The Servicer agrees to
cooperate with the Trustee in effecting the termination of the Servicer's
responsibilities and rights hereunder and shall promptly provide the Trustee all
documents and records whether in written or electronic form reasonably requested
by it to enable it to assume the Servicer's functions hereunder and shall
promptly also transfer to the Trustee of this Agreement all amounts which then
have been or should have been deposited in the Custodial Account for P&I by the
Servicer or which are thereafter received with respect to the Loans as well as
any escrowed funds held by it or in connection with its servicing activities
hereunder. The Servicer and the Trustee shall give each Rating Agency notice of
any Event of Default. If the Servicer shall within two Business Days following
such suspension remit to the Trustee the amount of any Advance the nonpayment of
which by the Servicer was an Event of Default described in clause (vi) of this
Section 7.1, the Trustee, subject to the last sentence of this paragraph, shall
permit the Servicer to resume its rights and obligations as Servicer hereunder.
The Servicer agrees that it will reimburse the Trustee for actual, necessary and
reasonable costs incurred by the Trustee because of action taken pursuant to
clause (vi) of this Section 7.1. The Servicer agrees that if an Event of Default
as described in clause (vi) of this Section 7.1 shall occur more than two times
in any twelve month period, the Trustee shall be under no obligation to permit
the Servicer to resume its rights and obligations as Servicer hereunder.

         Section 7.2 Other 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 7.1, 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 7.3 Directions by Certificateholders and Duties of Trustee
During Event of Default. During the continuance of any Event of Default, Holders
of Certificates evidencing, in aggregate, not less than 25% of the Trust Fund or
51% of the aggregate Percentage Interests of any Class of Certificates 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 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, (i) the
conducting or defending of any administrative action or litigation hereunder or
in relation hereto and (ii) 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 8.1, the Trustee
shall have the right to decline to follow any such direction if the Trustee, in
accordance with 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 or if the
Trustee has received contrary directions pursuant to this Section 7.3.

         Section 7.4 Action upon Certain Failures of Servicer and upon Event of
Default. In the event that the Trustee shall have knowledge of any failure of
the Servicer specified in Section 7.1(i) or (ii) 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. In the event that the Trustee shall
have knowledge of an Event of Default, the Trustee shall give prompt written
notice thereof to the Certificateholders and to each Rating Agency. For all
purposes of this Agreement, in the absence of actual knowledge by a Responsible
Officer of the Trustee, the Trustee shall not be deemed to have knowledge of any
failure of the Servicer as specified in Section 7.1 or any Event of Default
unless notified thereof in writing by the Servicer or by a Certificateholder.

         Section 7.5 Appointment of Successor Servicer.

         (a) When the Servicer receives a notice of termination pursuant to
Section 7.1 or the Trustee receives the resignation of the Servicer evidenced by
an Opinion of Counsel pursuant to Section 6.4, the Trustee shall become the
successor in all respects to the Servicer in its capacity

                                       78

<PAGE>

as Servicer under this Agreement and the transactions set forth or provided
for herein, provided, however, that the Trustee's obligation to make
any Advances shall be no greater than set forth in Section 4.3 of this
Agreement, and the Trustee shall have all the rights and powers and be subject
to all the responsibilities, duties and liabilities relating thereto placed on
the Servicer by the terms and provisions hereof and in its capacity as such
successor shall have the same limitation of liability herein granted to the
Servicer and provided, further, that the Trustee shall not be required to make
an Advance from its own funds if such Advance would be prohibited by law. As
compensation therefor, the Trustee shall be entitled to receive monthly an
amount not to exceed the Servicing Fee as agreed by the Trustee and the
Depositor, together with such other servicing compensation in the form of
assumption fees, late charges, prepayment fees or otherwise provided in Section
3.9. If the agreed amount is less than the Servicing Fee, the excess shall be
paid to the Class R Certificateholders. If the Trustee and the Depositor shall
not agree on the amount of such compensation, the Trustee shall solicit bids for
a successor servicer as described in Section 7.5(b), provided, however, if no
successor servicer is obtained through the bidding process, the Trustee may act
as such, or may pursuant to Section 7.5(b) appoint a successor servicer to act
as such, for the Servicing Fee together with such other servicing compensation
as provided in Section 3.9. In no event shall the Trustee's assumption of or
succession to the obligations of the Servicer make the Trustee liable for any
actions or omissions of the Servicer in its capacity as Servicer.

         (b) Notwithstanding the above, the Trustee may and shall, if it is
unable (or unwilling due to disagreement on compensation as provided in Section
7.5 (a)) to act as Servicer, appoint, or petition a court of competent
jurisdiction to appoint, any established housing and home finance institution,
bank or mortgage servicing institution which is an approved FNMA or FHLMC
servicer having a net worth of not less than $15,000,000 and meeting such other
standards as are set forth in Section 6.4 hereof for a successor to the Servicer
hereunder in the assumption of all or any part of the responsibilities, duties
or liabilities of the Servicer hereunder (except the repurchase obligations set
forth in Sections 2.2 and 2.3 hereof, which shall remain obligations of the
Depositor); provided, however, that until such appointment and assumption, the
Trustee will continue to perform the servicing obligations pursuant to this
Agreement (and until such time shall be entitled to receive the Servicing Fees
pursuant to Section 3.9); provided, further, that prior to the appointment of
any successor servicer, the Rating Agencies confirm that the appointment of such
successor servicer would not result in the downgrade of the Rating assigned to
any Class of Certificates. The compensation of any successor servicer so
appointed shall be equal to the Servicing Fees specified in Section 3.9 together
with such other compensation as is provided in said Section 3.9. In the event
the Trustee is required to solicit bids as provided above, the Trustee shall
solicit, by public announcement, bids from housing and home finance
institutions, banks and mortgage servicing institutions acceptable to the
Trustee and meeting the qualifications set forth above in this Section 7.5(b)
for the purchase of the servicing functions. Such public announcement shall
specify that the successor servicer shall be entitled to the full amount of the
Servicing Fee on the aggregate unpaid principal balance of the Loans as
servicing compensation for servicing the Loans, together with the other
servicing compensation in the form of assumption fees, late payment charges,
prepayment fees or otherwise as provided in Section 3.9. Within 45 days after
any such public announcement, the Trustee shall negotiate and effect the sale,
transfer and assignment of the servicing rights and responsibilities hereunder
(except the repurchase obligations set forth in Sections 2.2 and 2.3 hereof,
which shall remain obligations of the Depositor) to the qualified party
submitting the

                                       79

<PAGE>

highest qualifying bid. The Trustee shall deduct all costs and expenses of any
public announcement and of any sale, transfer and assignment of the servicing
rights and responsibilities hereunder from any sum received by the Trustee
from the successor to the Servicer in respect of such sale, transfer and
assignment. After such deductions, the remainder of such sum shall be paid by
the Trustee to the Class R Certificateholders at the time of such sale, transfer
and assignment to the Servicer's successor.

         (c) In the event that the Servicer resigns or is terminated in
accordance with the terms of this Agreement, the Servicer agrees to cooperate
with the Trustee and any successor servicer in effecting the termination of the
Servicer's servicing responsibilities and rights hereunder and shall promptly
provide the Trustee or such successor servicer, as applicable, all documents and
records reasonably requested by it to enable it to assume the Servicer's
functions hereunder and shall promptly also transfer to the Trustee or such
successor servicer, as applicable, all amounts which then have been or should
have been deposited in the Custodial Account for P&I by the Servicer or which
are thereafter received with respect to the Loans. Neither the Trustee nor any
other successor servicer shall be deemed to be in default hereunder by reason of
any failure to make, or any delay in making, any distribution hereunder or any
portion thereof caused by the failure of the Servicer to deliver, or any delay
in delivering, cash, documents or records to it.

         Section 7.6 Notification to Certificateholders. Upon any termination of
the Servicer or appointment of a successor to the Servicer, in each case as
provided herein, the Trustee shall as soon as practicable give written notice
thereof to Certificateholders at their respective addresses appearing in the
Certificate Register and each Rating Agency.

                                  ARTICLE VIII

                             CONCERNING THE TRUSTEE

         Section 8.1 Duties of Trustee. The Trustee, prior to the occurrence of
an Event of Default and after the curing 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 (which has not been cured), the Trustee, subject to the provisions of
Sections 7.1, 7.3, 7.4 and 7.5, 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 prudent person would exercise or use under the circumstances
in the conduct of such person's own affairs. Any permissive right of the Trustee
enumerated in this Agreement shall not be construed as a duty.

         Subject to Sections 8.2(i), 8.3 and 8.4, 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 are in the form required by this Agreement; provided,
however, that the Trustee shall not be responsible for the accuracy or content
of any resolution, certificate, statement, opinion, report, document, order or
other instrument furnished by any party hereunder. If any such instrument is
found not to conform to the requirements of this Agreement in a material manner,
the Trustee shall take action as it deems appropriate to have the instrument
corrected, and if the instrument is not corrected to the

                                       80

<PAGE>

Trustee's reasonable satisfaction, the Trustee will provide notice thereof to
the Certificateholders and each Rating Agency.

         No provision of this Agreement shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act or its own willful misconduct or in the event the Trustee is acting as
successor servicer pursuant to Section 7.5, to the standard imposed on the
Servicer pursuant to Section 6.3 of this Agreement; provided, however, that:

               (i) Prior to the occurrence of an Event of Default and after the
         curing 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 and conforming to the requirements of
         this Agreement;

               (ii) The Trustee 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 this Agreement or at the direction of
         Certificateholders holding Certificates which have an aggregate
         Certificate Principal Balance aggregating not less than 25% of the
         aggregate Certificate Principal Balance of all Certificates relating to
         the time, method and place of conducting any proceeding for any remedy
         available to the Trustee, or exercising or omitting to exercise any
         trust or power conferred upon the Trustee, under this Agreement;

               (iii) The Trustee shall not be liable in its individual capacity
         for any error of judgment made in good faith by any Responsible
         Officer, unless it shall be proved that the Trustee or such Responsible
         Officer was negligent in ascertaining the pertinent facts;

               (iv) The Trustee shall not be liable for any act or omission of
         the Depositor or the Servicer (except for its own acts or omissions as
         Servicer hereunder) or for any but its own acts or omissions;

               (v) The Trustee shall not be deemed to take notice or be deemed
         to have knowledge of any matter, including without limitation any
         default or Event of Default, unless written notice thereof, referring
         to the Certificates, the Depositor, the Trust Fund or this Agreement is
         received by a Responsible Officer of the Trustee at its Corporate Trust
         Office;

               (vi) Subject to the other provisions of this Agreement and
         without limiting the generality of this Section 8.1, the Trustee shall
         have no duty (A) to see to any recording, filing, or depositing of this
         Agreement or any agreement referred to herein or any financing
         statement or continuation statement evidencing a security interest, or
         to see to the maintenance of any such recording or filing or depositing
         or to any rerecording, refiling or redepositing of any thereof, (B) to
         see any insurance, (C) to see to the payment or discharge of any tax,

         encumbrance of any kind owing with respect to, assessed or levied
         against, any part of the Trust Fund other than from funds available in
         the Certificate Account, and (D) to confirm or verify the contents of
         any reports or certificates of the Servicer delivered to the Trustee
         pursuant to this Agreement believed by the Trustee to be genuine and to
         have been signed or presented by the proper party or parties;

               (vii) No provision of this Agreement shall require the Trustee to
         expend or risk its own funds or otherwise incur any financial liability
         in the performance of its duties hereunder (except for the giving of
         required notices), or in the exercise of any of its rights and powers,
         if it shall have reasonable grounds for believing the repayment of such
         funds or adequate indemnity against such risk or liability is not
         reasonably assured to it; and

               (viii) When the Trustee is acting as the Servicer pursuant to
         Section 7.5, and to the extent permitted under applicable law, the
         Trustee is hereby authorized, in making or disposing of any investment
         permitted hereunder, to deal with itself (in its individual capacity)
         or with any one or more of its Affiliates, whether its Affiliate is
         acting as an agent of the Trustee or of any third person or dealing as
         principal for its own account.

         None of the provisions contained in this Agreement shall require the
Trustee to expend or risk its own funds or otherwise incur 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 there is reasonable ground for believing that
repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it, and none of the provisions contained in this
Agreement shall in any event require the Trustee to perform, or be responsible
for the manner of performance of, any of the obligations of the Servicer under
this Agreement except during such time, if any, as the Trustee shall be the
successor to, and be vested with the rights, duties, powers and privileges of,
the Servicer in accordance with the terms of this Agreement.

          Section 8.2 Certain Matters Affecting Trustee. Except as
otherwise provided in Section 8.1:

               (i) Before acting or refraining from acting the Trustee may
         request or require an Officer's Certificate; the Trustee may rely and
         shall be protected in acting or refraining from acting upon any
         resolution, Officer's Certificate, opinion of counsel, 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 advice or
         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 advice or Opinion
         of Counsel;

               (iii) 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;

                                       82
<PAGE>

               (iv) The right of the Trustee to perform any discretionary act
         enumerated in this Agreement shall not be construed as a duty, and the
         Trustee shall not be answerable for other than its negligence or
         willful misconduct in the performance of such act;

               (v) The Trustee shall not be required to give any bond or surety
         in respect of the execution of the Trust Fund created hereby or the
         powers granted hereunder; 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, attorneys or custodians, and the Trustee shall not be
         responsible for any misconduct or negligence on the part of any such
         agent, attorney or custodian appointed by the Trustee with care. Any
         such agents, attorneys or custodians shall be entitled to all
         indemnities and protection afforded to the Trustee. Any designee of the
         Trustee shall be considered its "agent" hereunder whether performing it
         as an independent contractor or otherwise.

         Section 8.3 Trustee Not Required to Make Investigation. Prior to the
occurrence of an Event of Default hereunder and after the curing of all Events
of Default which may have occurred, the Trustee shall not be bound to ascertain
or inquire as to the performance or observance of any of the terms, conditions,
covenants or agreements herein or to make any investigation into the facts or
matters stated in any resolution, certificate, statement, instrument, opinion,
report, notice, request, consent, order, approval, bond, Mortgage, Mortgage Note
or other paper or document, unless requested in writing so to do by Holders of
Certificates having a Percentage Interest not less than 51% of the Trust Fund;
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
as a condition to such proceeding. The reasonable expense of every such
examination shall be paid by the Depositor or, if paid by the Trustee, shall be
repaid by the Depositor upon demand.

         Section 8.4 Trustee Not Liable for Certificates or Loans. The recitals
contained herein and in the Certificates (other than the certificate of
authentication on the Certificates) shall be taken as the statements of the
Depositor, and the Trustee assumes no responsibility for the correctness of the
same. The Trustee makes no representations or warranties as to the validity or
sufficiency of this Agreement or of the Certificates or of any Loan or related
document. The Trustee shall not be accountable for the use or application by the
Depositor of any of the Certificates or of the proceeds of such Certificates or
for the use or application of any funds paid to the Servicer in respect of the
Loans or deposited in or withdrawn from the Custodial Account for P&I by the
Servicer or for investment of any such amounts. The Trustee shall not be
responsible for the legality or validity of this Agreement or the validity,
priority, perfection or sufficiency of the security for the Certificates issued
or intended to be issued hereunder. The Trustee shall have no responsibility for
filing any financing or continuation statement in any public office at any time
or to otherwise perfect or maintain the perfection of any security interest or
lien granted to it hereunder or to record this Agreement.

         Neither the Trustee nor any of the directors, officers, employees or
agents of the Trustee shall be under any liability to the Trust Fund or the
Certificateholders for any action taken or for

                                       83

<PAGE>

refraining from the taking of any action in good faith pursuant to this
Agreement, or for errors in judgment while an Event of Default exists; provided,
however, that this provision shall not protect the Trustee or any such person
against any liability which would otherwise be imposed by reason of willful
misfeasance, bad faith or negligence in the performance of duties. The Depositor
hereby agrees to indemnify and hold harmless the Trustee and any director,
officer, employee or agent of the Trustee against any loss, liability or
expense, including reasonable attorneys' fees, incurred in connection with or
related to the Trustee's performance of its powers and duties under this
Agreement (including, without limitation, performance under Section 8.1 hereof),
or any action relating to this Agreement or the Certificates, or the performance
of the Trustee's duties hereunder, or, for so long as the Custodian is LaSalle
Bank National Association, relating to any acts or omissions of the Custodian
under the Custodial Agreement (other than any acts of the Custodian caused by
its own negligence) other than any loss, liability or expense incurred by any
such Person by reason of willful misfeasance, bad faith or negligence in the
performance of duties. Any such losses, liabilities and expenses resulting
therefrom shall be losses, liabilities and expenses of the Depositor. The
indemnification provided hereunder shall survive termination of this Agreement.

         Section 8.5 Trustee May Own Certificates. The Trustee and any agent of
the Trustee in its individual or any other capacity may become the owner of or a
pledgee of the Certificates with the same rights it would have if it were not
Trustee or such agent, and may otherwise deal with the parties hereto.

         Section 8.6 Servicer to Pay Trustee's Fees and Expenses. The Servicer
covenants and agrees to pay to the Trustee monthly (or as otherwise agreed), and
the Trustee shall be entitled to receive, reasonable compensation (which shall
not be limited by any provision of law in regard to the compensation of a
trustee of an express trust) for all services rendered by it in the execution of
the trusts hereby created and in the exercise and performance of any of the
powers and duties hereunder of the Trustee (including any custodial services),
and the Servicer shall pay or reimburse the Trustee upon its request for all
reasonable and usual expenses, disbursements and advances, including reasonable
attorneys' fees, incurred or made by the Trustee in accordance with any of the
provisions of this Agreement (including the reasonable compensation and the
expenses and disbursements of its counsel and of all persons not regularly in
its employ) except any such expense, disbursement or advance as may arise from
its negligence or bad faith. The Tax Matters Person (or Person acting as its
attorney-in-fact or agent) shall indemnify the Trustee for any liability of or
assessment against the Trustee resulting from any error in any tax or tax
information returns prepared or caused to be prepared by such Person. In the
event that (i) the Servicer does not pay to the Trustee any compensation owed to
the Trustee pursuant to this Agreement or (ii) the Trustee is not reimbursed for
any expense, disbursement or advance incurred or made by the Trustee pursuant to
this Agreement, the Trustee shall be entitled to withdraw and retain such amount
from the Certificate Account. In the event the Trustee incurs expenses or
renders services in any proceedings which result from an Event of Default under
Section 7.1, subsections (iii), (iv) or (v) of this Agreement, or from any
default which, with the passage of time, would become an Event of Default, the
expenses so incurred and compensation for services so rendered are intended to
constitute expenses of administration under the United States Bankruptcy Code or
equivalent law.

         Section 8.7 Eligibility Requirements for Trustee. The Trustee hereunder
shall at all times be a corporation or association organized and doing business
under the laws of any state of the United States of America, authorized under
such laws to exercise corporate trust powers, having a combined capital and
surplus of at least $50,000,000 and subject to supervision or examination by
federal or state authority. The Trustee shall not control the Servicer nor be a
parent of or a subsidiary of the Servicer. If such corporation or 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 8.7 the combined capital and surplus of such
corporation or 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
provisions of this Section 8.7, the Trustee shall resign immediately in the
manner and with the effect specified in Section 8.8.

         Section 8.8 Resignation and Removal of Trustee. The Trustee may at any
time resign and be discharged from the trusts hereby created by giving written
notice of resignation to the Servicer. Such notice shall also be furnished to
each Rating Agency. Upon receiving such notice of resignation, the Servicer
shall promptly appoint a 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 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 at the expense of the
Depositor.

         If at any time the Trustee shall cease to be eligible in accordance
with the provisions of Section 8.7 and shall fail to resign after written
request for the Trustee's resignation by the Servicer, or if at any time the
Trustee shall become incapable of acting, or shall be adjudged 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, with or without cause, 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 trustee.

         The Holders of Certificates having a Percentage Interest aggregating
not less than 51% of the aggregate Denomination of all Certificates may at any
time remove the Trustee and appoint a successor trustee by written instrument or
instruments, in triplicate, signed by such holders or their attorneys-in-fact
duly authorized, one complete set of which instrument or instruments shall be
delivered to the Servicer, one complete set to the Trustee so removed and one
complete set to the successor trustee so appointed.

         Any resignation or removal of the Trustee and appointment of successor
trustee pursuant to any of the provisions of this Section 8.8 shall become
effective only upon acceptance of appointment by the successor trustee as
provided in Section 8.9.

         Section 8.9 Successor Trustee. Any successor trustee appointed as
provided in Section 8.8 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

                                       85

<PAGE>

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 deliver or cause to be delivered to the successor
trustee all Mortgage Files and related documents and statements held by it
hereunder (other than any Mortgage Files at the time held by the Custodian, if
it shall agree to become the agent of any successor trustee hereunder), and the
Servicer and the predecessor trustee shall execute and deliver such instruments
and do such other things as may reasonably be required for more fully and
certainly vesting and confirming in the successor trustee all such rights,
powers, duties and obligations.

         No successor trustee shall accept appointment as provided in this
Section 8.9 unless at the time of such acceptance such successor trustee shall
be eligible under the provisions of Section 8.7.

         Upon acceptance of appointment by a successor trustee as provided in
this Section 8.9, the Servicer shall 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 fails 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 8.10 Merger or Consolidation of Trustee. Any Person into which
the Trustee may be merged or converted or with which it may be consolidated, or
any Person resulting from any merger, conversion or consolidation to which the
Trustee shall be a party, or any Person succeeding to all or substantially all
of the corporate trust business of the Trustee, shall be the successor of the
Trustee hereunder, provided, that such Person shall be eligible under the
provisions of Section 8.7, 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 8.11 Appointment of Co-Trustee or Separate Trustee.
Notwithstanding any other provisions hereof, at any time, for the purpose of
meeting any legal requirements of any jurisdiction in which any part of the
Trust Fund or property securing the same may at the time be located, 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 to act as co-trustee or co-trustees, jointly with the Trustee, or
separate trustee or separate trustees, of all or any part of the Trust Fund, and
to vest in such Person or Persons, in such capacity, such title to the Trust
Fund, or any part thereof, and, subject to the other provisions of this Section
8.11, 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 15 days after the receipt by it of a request
so to do, or in case an Event of Default shall have occurred and be continuing,
the Trustee alone shall have the power to make such appointment. Each co-trustee
separate trustee hereunder shall not be required to meet the terms of
eligibility as a successor trustee under Section 8.7 hereunder and no notice to
holders of Certificates of the appointment of co-trustee(s) or separate
trustee(s) shall be required under Section 8.9 hereof.

                                       86
<PAGE>

         In the case of any appointment of a co-trustee or separate trustee
pursuant to this Section 8.11, 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 Fund or a
portion thereof in any such jurisdiction) shall be exercised and performed by
such separate trustee or co-trustee at the direction of the Trustee.

         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 VIII. 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. The Trustee shall not be responsible
for any action or inaction of any such separate trustee or co-trustee. If any
separate trustee or co-trustee shall die, become incapable of acting, resign or
be removed, 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.

         The Trustee may appoint one or more Eligible Institutions to act as its
agent or agents to perform any or all of its duties and obligations under this
Agreement. Each such agent shall be subject to all of 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.

         Section 8.12 Appointment of Custodians. The Trustee may, with the
consent of the Servicer, appoint one or more Custodians, not affiliated with the
Depositor, to review, pursuant to Section 2.2 hereof, and hold all or a portion
of the Mortgage Files as agent for the Trustee provided, however, that such
appointed Custodian may be LaSalle Bank National Association. Any Custodian
appointed shall be an institution subject to supervision by federal or state
authority, shall have combined capital and surplus of at least $50,000,000 and
shall be qualified to do business in the jurisdiction in which it holds any
Mortgage File.

         Section 8.13 Authenticating Agent.

         (a) The Trustee may appoint from time to time an authenticating agent
(the "Authenticating Agent") which shall be authorized to act on behalf of the
Trustee in authenticating Certificates. Wherever reference is made in this
Agreement to the authentication

                                      87

<PAGE>

of Certificates by the Trustee or the Trustee's certificate of
authentication, such reference shall be deemed to include authentication on
behalf of the Trustee by the Authenticating Agent and a certificate of
authentication executed on behalf of the Trustee by the Authenticating Agent.
Any successor Authenticating Agent must be acceptable to the Servicer and have a
principal office and place of business in Boston, Massachusetts, New York, New
York or Chicago, Illinois, have a combined capital and surplus of at least
$50,000,000, and be authorized to do a trust business and subject to supervision
or examination by federal or state authorities.

         (b) Any corporation into which the Authenticating 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 the Authenticating Agent
shall be a party, or any corporation succeeding to all or substantially all of
the corporate agency business of the 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.

         (c) The Authenticating Agent may at any time resign by giving at least
30 days' advance written notice of resignation to the Trustee and to the
Servicer. The Trustee may at any time terminate the agency of the Authenticating
Agent by giving written notice of termination to the Authenticating Agent and to
the Servicer. Upon receiving a notice of resignation or upon such a termination,
or in case at any time the Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section 8.13, the Trustee promptly shall
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 herein. No successor Authenticating
Agent shall be appointed unless eligible under the provisions of this Section
8.13.

         (d) The Authenticating Agent shall have no responsibility or liability
for any action taken by it as such at the direction of the Trustee. Any
reasonable compensation paid to the Authenticating Agent shall be a reimbursable
expense under Section 8.6.

         Section 8.14 Bloomberg. As soon as practicable after the Closing Date,
the Servicer will arrange with Bloomberg to have the Depositor set up on
Bloomberg to provide the information set forth on Exhibit Q (the "Data") with
respect to the Loans on a monthly basis in a format acceptable to Bloomberg and
acceptable to the Underwriters. During the term of this Agreement, the Servicer
will provide updated Data to Bloomberg on or before each Distribution Date.

         Section 8.15 Reports to Securities and Exchange Commission. Unless
otherwise directed by the Depositor in writing, the Servicer shall prepare, sign
and file with the Securities and Exchange Commission, on behalf of the
Depositor, (i) no later than ten days after each Distribution Date, the
Certificateholders' Report on the appropriate form and in the appropriate medium
authorized or prescribed therefor under the

                                       88

Exchange Act, (ii) no later than March 25 of each calendar year, an
annual report meeting the requirements of the Exchange Act on the appropriate
form and in the appropriate medium authorized or prescribed therefor under the
Exchange Act. The Servicer shall promptly forward copies of all filings made
pursuant to this Section 8.15 to the Depositor.

         Section 8.16 [Reserved].

                                   ARTICLE IX

The Trustee or its agent shall give such notice to the Certificate Registrar and
each Rating Agency at the time such notice is given to the Certificateholders.
Upon any such termination, the duties of the Certificate Registrar shall also
terminate. In the event such notice is given in connection with Servicer's
election to purchase,

                                       89

<PAGE>

the Servicer shall deposit in the Certificate Account on the related Withdrawal
Date an amount equal to the above-described purchase price and upon such deposit
Certificateholders will be entitled to the amount of such purchase price but not
amounts in excess thereof, all as provided herein. With respect to the
Certificates, upon presentation and surrender of the Certificates pursuant to
any termination under this Section 9.1, the Trustee or Paying Agent shall cause
to be distributed to Certificateholders an amount equal to (a) the amount
otherwise distributable on such Distribution Date, if not in connection with a
purchase; or (b) if the Servicer elected to so purchase, the purchase price
calculated as above provided. Upon any termination pursuant to clause (iii)
above, or upon certification to the Trustee by a Servicing Officer following
such final deposit, the Trustee and any Custodian shall promptly release to the
Servicer the Mortgage Files for the remaining Loans, and the Trustee shall
execute all assignments, endorsements and other instruments necessary to
effectuate such transfer.

         In the event that all of the Certificateholders shall not surrender
their Certificates for cancellation within three months after the time specified
in the above-mentioned written notice, the Trustee or its agent 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 three months after the second notice all the Certificates
shall not have been surrendered for cancellation, the Trustee or its agent shall
take appropriate and reasonable steps as directed by the Servicer, to contact
the remaining Certificateholders concerning surrender of their Certificates, and
the cost thereof shall be paid out of the funds and other assets which remain in
trust hereunder.

         Section 9.2 Trusts Irrevocable. Except as expressly provided herein,
all trusts created hereby are irrevocable.

         Section 9.3 Additional Termination Requirements.

         (a) In the event the Servicer exercises its purchase option as provided
in Section 9.1, the Trust Fund 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 Fund to comply with the
requirements of this Section 9.3 will not (i) result in the imposition of taxes
on "prohibited transactions" of REMIC I or REMIC II of the Trust Fund as
described in Section 860F(a)(2) of the Code, or (ii) cause either REMIC I or
REMIC II of the Trust Fund to fail to qualify as a REMIC at any time that any
Certificates are outstanding:

               (A) Within 90 days prior to the final Distribution Date set forth
         in the notice given by the Depositor under Section 9.1, the Tax Matters
         Person shall prepare the documents associated with and shall adopt a
         plan of complete liquidation of each of REMIC I and REMIC II of the
         Trust Fund; and

               (B) At or after the time of adoption of such a plan of complete
         liquidation and at or prior to the final Distribution Date, the
         Servicer as agent of the Trustee shall sell all of the assets of the
         Trust Fund to the Depositor for cash in accordance with such plan of
         liquidation; provided, however, that in the event that a calendar
         quarter ends after the time of adoption of such a plan of complete

                                       90

<PAGE>

         liquidation but prior to the final Distribution Date, the Servicer
         shall not sell any of the assets of the Trust Fund prior to the close
         of that calendar quarter.

         (b) The Tax Matters Person hereby agrees to adopt such a plan of
complete liquidation and to take such other action in connection therewith as
may be reasonably requested by the Servicer.

                            MISCELLANEOUS PROVISIONS

         Section 10.1 Amendment. This Agreement may be amended from time to time
by the Depositor, Servicer and the Trustee, without the consent of any of the
Certificateholders, (a) to cure any ambiguity, to correct or supplement any
provision herein which may be inconsistent with any other provision herein, or
to make any other provisions with respect to matters or questions arising under
this Agreement, (b) to modify, eliminate or add to any provisions to such extent
as shall be necessary to maintain the qualification of the Trust Fund as a REMIC
at all times that any Class A or Subordinate Certificates are outstanding,
provided, that the Trustee has received an Opinion of Counsel to the effect that
such action is necessary or desirable to maintain such qualification, provided,
that such action under clauses (a) and (b) above shall not adversely affect in
any material respect the interests of any Certificateholder or (c) such
amendment is made to conform the terms of this Agreement to the terms described
in the Prospectus dated October 12, 1999, together with the Prospectus
Supplement dated April 27, 2001.

         This Agreement may also be amended from time to time by the Depositor,
Servicer and the Trustee with the consent of the Holders of Certificates
evidencing, in aggregate, not less than 50% of the Trust Fund for the purpose of
adding any provisions 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 Certificates; provided, however, that no such amendment shall (a)
reduce in any manner the amount of, or delay the timing of, payments received on
Loans which are required to be distributed in respect of any Certificate without
the consent of the Holder of such Certificate; (b) adversely affect in any
material respect the interest of the Holders of the Class A Certificates in a
manner other than as described in (a) above without the consent of the Holders
of Class A Certificates aggregating not less than 66-2/3% of the aggregate
Percentage Interest evidenced by all Class A Certificates; (c) adversely affect
in any material respect the interest of the Holders of the Subordinate
Certificates in a manner other than as described in clause (a) above without the
consent of the Holders of Subordinate Certificates aggregating not less than

Certificates; (d) adversely affect in any material respect the interest of the
Class R Certificateholders without the consent of the Holder of the Class R

the Servicer or successor Servicer under this Agreement without the prior
written consent of such party; or (f) reduce the aforesaid percentage of the
Certificates the Holders of which are required to consent to any such amendments
without the consent of the Holders of all Certificates then outstanding;
provided, that for the purposes of this Agreement, the Holders of the Class R
Certificates shall have no right to vote at all times that any Class A
Certificates or Subordinate

                                       91

<PAGE>

Certificates are outstanding if such amendment relates to the modification,
elimination or addition of any provision necessary to maintain the qualification
of the Trust Fund as a REMIC.

         Notwithstanding any contrary provision of this Agreement, the Trustee
shall not consent to any amendment to this Agreement unless it shall have first
received an Opinion of Counsel to the effect that such amendment will not cause
either REMIC I or REMIC II of the Trust Fund to fail to qualify as a REMIC at
any time that any REMIC I Regular Interests or REMIC II Certificates are
outstanding.

         As soon as practicable after the execution of any such amendment, the
Trustee shall furnish written notification of the substance of such amendment to
each Certificateholder and each Rating Agency.

         It shall not be necessary for the consent of the Certificateholders
under this Section 10.1 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 regulations as the Trustee may prescribe.

         Prior to the execution of any amendment to this Agreement, the Trustee
shall be entitled to receive and rely upon an Opinion of Counsel stating that
the execution of such amendment is authorized or permitted by this Agreement.
The Trustee may, but shall not be obligated to, enter into any such amendment
which affects the Trustee's own rights, duties or immunities under this
Agreement.

         Section 10.2 Recordation of Agreement. This Agreement (or an abstract
hereof, if acceptable by the applicable recording office) 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 at its expense, but only after the Depositor has delivered to the
Trustee an Opinion of Counsel to the effect that such recordation materially and
beneficially affects the interests of the Certificateholders. Without limiting
the foregoing, the Trustee shall make the filings required by Chapter 182 of the
Massachusetts General Laws.

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

         Except as otherwise expressly provided herein no Certificateholder,
solely by virtue of its status as Certificateholder, shall have any right to
vote or in any manner otherwise control the

                                       92

<PAGE>

operation and management of the Trust Fund, 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, solely by virtue of its status as
Certificateholder, shall have any right by virtue or by availing of any
provision 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 hereinbefore provided, and unless all of the
Holders of Certificates evidencing, in aggregate, not less than 25% of the Trust
Fund 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 of any provision of this Agreement to affect, disturb
or prejudice the rights of the Holders of any other of such 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 benefit of all Certificateholders. For the protection and
enforcement of the provisions of this Section 10.3, each and every
Certificateholder and the Trustee shall be entitled to such relief as can be
given either at law or in equity.

         Section 10.4 Governing Law; Jurisdiction. THIS AGREEMENT SHALL BE
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK (WITHOUT REGARD
TO CONFLICTS OF LAWS PRINCIPLES), AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF

         Section 2. Representations and Warranties of the Purchaser. In
connection with the proposed transfer, the Purchaser represents and warrants to
AAMC, the Servicer, the Certificate Registrar and the Trustee that:

         (a) The Purchaser is duly organized, validly existing and in good
standing under the laws of the jurisdiction in which the Purchaser is organized,
is authorized to invest in the Purchased Certificates, and to enter into this
Agreement, and duly executed and delivered this Agreement;

         (b) The Purchaser is acquiring the Purchased Certificates for its own
account as principal and not with a view the distribution thereof, in whole or
in part;

         (c) The Purchaser is an "accredited investor" as such term is defined
in paragraph (a)(1), (a)(2), (a)(3), (a)(7) or (a)(8) of Section 501 of

<PAGE>

Securities Act of 1933, as amended (the "Act"), has knowledge of financial and
business matters and is capable of evaluating the merits and risks of an
investment in the Purchased Certificates; the Purchaser has sought such
accounting, legal and tax advice as it has considered necessary to make an
informed investment decision; and the Purchaser is able to bear the economic
risk of an investment in the Purchased Certificates and can afford a complete
loss of such investment;

         (d) The Purchaser is not affiliated with the Trustee;

         (e) The Purchaser confirms that AAMC has made available to the

         (f) If applicable, the Purchaser has complied, and will continue to

expense of the Trustee, the Certificate Registrar or AAMC. Any such
Certificateholder desiring to effect such transfer shall, and does hereby agree
to, indemnify the Trustee and AAMC 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.

transferee provides AAMC, the Certificate Registrar and the Trustee with (i) a
Transferee's Agreement, substantially in the form of this Agreement, and (ii) an
affidavit substantially in the form of Exhibit A hereto that the proposed

reasonable investigation of the financial condition of the Purchaser and, as a
result of the investigation, found that the Purchaser has historically paid its
debts as they came due, and found no significant evidence to indicate that the
Purchaser will not continue to pay its debts as they come due in the future, and

                                      I-1
<PAGE>

(ii) either (A) the Seller both (1) has determined all of the following (I) at
the time of the transfer, and at the close of each of the Purchaser's two fiscal
years preceding the year of transfer, the Purchaser's gross assets for financial
reporting purposes exceed $100 million and its net assets for such purposes
exceed $10 million (disregarding, for purposes of determining gross or net
assets, the obligation of any person related to the Purchaser within the meaning
of section 860L(g) of the Code or any other asset if a principal purpose for
holding or acquiring that asset is to permit the Purchaser to satisfy this
minimum gross asset or net asset requirement), (II) the Purchaser is a domestic
C corporation for United States federal income tax purposes that is not for such
purposes an exempt corporation, a regulated investment company, a real estate
investment trust, a REMIC, or a cooperative organization to which part I of
subchapter T of the Code applies, (III) there are no facts or circumstances on
or before the date of transfer (or anticipated) which would reasonably indicate
that the taxes associated with the Certificates will not be paid, (IV) the
Purchaser is not a foreign branch of a domestic corporation, and (V) the
transfer does not involve a transfer or assignment to a foreign branch of a
domestic corporation (or any other arrangement by which any Certificate is at
any time subject to net tax by a foreign country or U.S. possession) and the
Purchaser will not hereafter engage in any such transfer or assignment (or any
such arrangement), and (2) does not know or have reason to know that the
Purchaser will not honor the restrictions on subsequent transfers of any Class R
Certificate described in paragraph 12 and 13 of the Transferee's Transfer
Affidavit, or (B) the Seller has determined that the present value of the
anticipated tax liabilities associated with the holding of the Certificates do
not exceed the sum of (1) the present value of any consideration given to the
Purchaser to acquire the Certificates, (2) the present value of the expected
future distributions on the Certificates, and (3) the present value of the
anticipated tax savings associated with holding the Certificates as the REMIC
generates losses (having made such determination by (I) assuming that the
Purchaser pays tax at a rate equal to the highest rat of tax specified in
Section 11(b)(1) of the Code, and (II) utilizing a discount rate for present
valuation purposes equal to the applicable Federal rate prescribed by Section
1274(d) of the Code compounded semi-annually (or a lower discount rate based on
the Purchaser having demonstrated that it regularly borrows, in the course of
its trade or business, substantial funds at such lower rate from unrelated third
parties)).

         6. The Purchaser has represented to the Seller that, if the
Certificates constitute a noneconomic residual interest, it (i) understands that
as holder of a noneconomic residual interest it may incur tax liabilities in
excess of any cash flows generated by the interest, and (ii) intends to pay
taxes associated with its holding of the Certificates as they become due.

         7. The Seller understands that the transfer of the Certificates may not
be respected by for United States income tax purposes (and the Seller may
continue to be liable for United States income taxes associated therewith)
unless there is compliance with the standards of paragraph 5 above as to any
transfer.

                                           Very truly yours,

                                           [Seller]

STATE OF ________    )
                     )   ss.
COUNTY OF _______    )

         [NAME OF OFFICER], being first duly sworn, deposes and says:

         1. That he is [Title of Officer] of [Name of Owner] (record or
beneficial owner of a Class R Certificate (the "Owner")), a [savings
institution] [corporation] duly organized and existing under the laws of [the
State of              ] [the United States], on behalf of which he makes this
affidavit and agreement.

         2. That the Owner (i) is not and will not be a "disqualified
organization" as of the [date of transfer] within the meaning of Section
860E(e)(5) of the Internal Revenue Code of 1986, as amended (the "Code") and
will endeavor to remain other than a disqualified organization for so long as it
retains its ownership interest in the Class R Certificate, and (ii) is acquiring
a Class R Certificate for its own account or for the account of another Owner
from which it has received an affidavit and agreement in substantially the same
form as this affidavit and agreement. (For this purpose, a "disqualified
organization" means the United States, any state or political subdivision
thereof, or any agency or instrumentality of any of the foregoing (other than an
instrumentality all of the activities of which are subject to tax and, except
for the Federal Home Loan Mortgage Corporation, a majority of whose board of
directors is not selected by any such governmental entity, or any foreign
government or international organization, or any agency or instrumentality of
such foreign government or organization, any rural electric or telephone
cooperative, or any organization (other than certain farmers' cooperatives) that
is generally exempt from federal income tax unless such organization is subject
to the tax on unrelated business taxable income).

         3. That the Owner is aware (i) of the tax that would be imposed on
transfers of the Class R Certificate; (ii) that such tax would be on the
transferor, or, if such transfer is through an agent (which person includes a
broker, nominee or middleman) for a disqualified organization, on the agent;
(iii) that the person otherwise liable for the tax shall be relieved of
liability for the tax if the transferee furnished to such person an affidavit
that the transferee is not a disqualified organization and, at the time of
transfer, such person does not have actual knowledge that the affidavit is
false; and (iv) that a Class R Certificate may represent "noneconomic residual
interests" within the meaning of 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,
if a significant purpose of the transfer was to enable the transferor to impede
the assessment or collection of tax.

         4. That the Owner is aware of the tax imposed on a "pass-through
entity" holding a Class R Certificate if at any time during the taxable year of
the pass-through entity a disqualified organization is the record holder of an
interest in such entity. (For this purpose, a "pass-through

                                      J-1
<PAGE>

entity" includes a regulated investment company, a real estate investment trust
or common trust fund, a partnership, trust or estate, and certain cooperatives.)

         5. That the Owner is aware that the Trustee and the Certificate
Registrar will not register the transfer of a Class R Certificate unless the
transferee, or other transferee's agent, delivers to each of them an affidavit
and agreement, among other things, in substantially the same form as this
affidavit and agreement. The Owner expressly agrees that it will not consummate
any such transfer if it knows or believes that any of the representations
contained in such affidavit and agreement are false.

         6. That the Owner has reviewed the restrictions set forth on the face
of each Class R Certificate and the provisions of Section 5.1 of the Pooling and
Servicing Agreement under which the Class R Certificates were issued. The Owner
expressly agrees to be bound by and to comply with such restrictions and
provisions.

         7. That the Owner consents to any additional restrictions or
arrangements that shall be deemed necessary upon advice of counsel to constitute
a reasonable arrangement to ensure that such Class R Certificate will only be
owned, directly or indirectly, by an Owner that is not a disqualified
organization.

         8. The Owner's Taxpayer Identification Number is ___________________.

         9. That no purpose of the Owner relating to the purchase of such Class
R Certificate by the Owner is or will be to enable the transferor to impede the
assessment or collection of tax.

         10. That the Owner has no present knowledge or expectation that it will
be unable to pay any United States taxes owed by it so long as any of the
Certificates remain outstanding.

         11. That the Owner has no present knowledge or expectation that it will
become insolvent or subject to a bankruptcy proceeding for so long as any of the
Certificates remain outstanding.

         12. The Owner will, in connection with any transfer that it makes of
the Class R Certificate, deliver to the Certificate Registrar a representation
letter substantially in the form of Exhibit I to the Pooling and Servicing
Agreement. [The Owner hereby agrees that it will not make any transfer of any
Class R Certificate unless (i) the transfer is to an entity which is a domestic
C corporation (other than an exempt corporation, a regulated investment company,
a real estate investment trust, a REMIC, or a cooperative organization to which
part I of Subchapter T of the Code applies) for federal income tax purposes, and
(ii) the transfer is in compliance with the conditions set forth in paragraph 5
of Exhibit I of the Pooling and Servicing Agreement.](1)/

compliance with the "Asset Test Safe Harbor" (which is generally described as
the second "safe harbor" in the Prospectus Supplement) rather then the "Formula

the Prospectus Supplement). See "Federal Income Tax

         13. The Owner (i) is a citizen or resident of the United States, a
corporation or partnership (including an entity treated as a corporation or
partnership for federal income tax purposes) created or organized in, or under
the laws of, the United States or any state thereof or the District of Columbia
(except, in the case of a partnership, to the extent provided in regulations) or
an estate whose income is subject to United States federal income tax regardless
of its source, or a trust if a court within the United States is able to
exercise primary supervision over the administration of the trust and one or
more such U.S. Persons have the authority to control all substantial decisions
of the trust, and (ii) if the Owner is a partnership for U.S. federal income tax
purposes, each person or entity which holds an interest (directly or indirectly,
through a pass-through entity) is a person or entity described in (i). To the
extent prescribed in regulations by the Secretary of the Treasury, which have
not yet been issued, a trust which was in existence on August 20, 1996 (other
than a trust treated as owned by the grantor under subpart E of part 1 of
subchapter J of chapter 1 of the Code), and which was treated as a U.S. Person
on August 20, 1996 may elect to continue to be treated as a U.S. Person
notwithstanding the previous sentence.

         14. The Owner hereby agrees to cooperate with the Depositor and to take
any action required of it by the Code or Treasury regulations thereunder
(whether now or hereafter promulgated) in order to create or maintain the REMIC
status of the REMIC I or the REMIC II.

         15. The Owner hereby agrees that it will not take any action that could
endanger the REMIC status of the REMIC I or the REMIC II, as applicable, or
result in the imposition of tax on the REMIC I or the REMIC II unless counsel
for, or acceptable to, the Depositor has provided an opinion that such action
will not result in the loss of such REMIC status or the imposition of such tax,
as applicable.

         16. The Owner as transferee of such Class R Certificate has represented
to their transferor that, if a Class R Certificate represents noneconomic
residual interests, the Owner (i) understands that as holder of a noneconomic
residual interest it may incur tax liabilities in excess of any cash flows
generated by the interest, and (ii) intends to pay taxes associated with its
holding of a Class R Certificate as they become due.

         [17. The Owner hereby represents to and for the benefit of the
transferor that (i) at the time of the transfer, and at the close of each of the
Owners's two fiscal years preceding the year of transfer, the Owners's gross
assets for financial reporting purposes exceed $100 million and its net assets
for such purposes exceed $10 million (disregarding, for purposes of determining
gross or net assets, the obligation of any person related to the Owner within
the meaning of section 860L(g) of the Code or any other asset if a principal
purpose for holding or acquiring that asset is to permit the Owner to satisfy
this minimum gross asset or net asset requirement), (ii) the Owner is a domestic
C corporation for United States federal income tax purposes that is not for such
purposes an exempt corporation, a regulated investment company, a real estate
investment trust, a REMIC, or a cooperative organization to which part I of
subchapter T of the Code applies, (iii) there are no facts or circumstances on
or before the date of transfer (or anticipated)

which would reasonably indicate that the taxes associated with the Class R
Certificate will not be paid, and (iv) the Owner is not a foreign branch of a
domestic corporation, the transfer does not involve a transfer or assignment to
a foreign branch of a domestic corporation (or any other arrangement by which
any Class R Certificate is at any time subject to net tax by a foreign country
or U.S. possession), and the Owner will not hereafter engage in any such
transfer or assignment (or any such arrangement).](2)

                     FORM OF ADDITIONAL MATTER INCORPORATED

                        INTO THE FORM OF THE CERTIFICATES

         This Certificate does not represent an obligation of or interest in ABN
AMRO Mortgage Corporation or any of its affiliates. Neither this Certificate nor
the underlying Loans are guaranteed by any agency or instrumentality of the
United States.

         This certifies that the above-mentioned Registered Owner is the
registered owner of certain interests in a trust fund (the "Certificate Trust
Fund") whose assets consist of, among other things, of a pool (the "Mortgage
Pool") of conventional one- to four-family mortgage loans (the "Loans"), formed
by ABN AMRO Mortgage Corporation (the "Depositor"). The Loans were originated or
acquired by various financial institutions and subsequently acquired by the
Depositor. The Mortgage Pool was created pursuant to a Pooling and Servicing
Agreement, dated as of the Cut-Off Date stated above (the "Pooling Agreement"),
between the Depositor, Washington Mutual Mortgage Securities Corp., as Servicer
(the "Servicer"), and State Street Bank and Trust Company, as Trustee (the
"Trustee"), a summary of certain of the pertinent provisions of which is set
forth hereafter. To the extent not defined herein, the capitalized terms used
herein have the meanings assigned in the Pooling Agreement. Nothing herein shall
be deemed inconsistent with such meanings, and in the event of any conflict
between the Pooling Agreement and the terms of this Certificate, the Pooling
Agreement shall control. This Certificate is issued under and is subject to the
terms, provisions and conditions of the Pooling Agreement, to which Pooling
Agreement the Holder of this Certificate, by virtue of the acceptance hereof,
assents and by which such Holder is bound.

         Distributions will be made, pursuant to the Pooling Agreement, on the
25th day of each month or, if such 25th day is not a Business Day, the Business
Day immediately following (the "Distribution Date"), commencing on the first
Distribution Date specified above, to the Person in whose name this Certificate
is registered at the close of business on the last Business Day of the month
immediately preceding the month of such distribution (the "Record Date"), to the
extent of such Certificateholder's Percentage Interest represented by this
Certificate in the portion of the Certificate Distribution Amount for such
Distribution Date then distributable on the Certificates of this Class, as
specified in Section 4.1 of the Pooling Agreement.

         Distributions on this Certificate will be made by the Trustee or its
Paying Agent by wire transfer or by other means of payment acceptable to each
Certificateholder of record on the immediately preceding Record Date.
Notwithstanding the above, the final distribution on this Certificate will be
made after due notice by the Trustee or its Paying Agent of the pendency of such
distribution and only upon presentation and surrender of this Certificate to the
Certificate Registrar.

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

                        MORTGAGE PASS-THROUGH CERTIFICATE

         This Certificate is one of a duly authorized issue of Certificates
designated as Mortgage Pass-Through Certificates of the Series and Class
specified hereon (herein called the "Certificates") and representing certain
interests in the Certificate Trust Fund.

         The Certificates do not represent an obligation of, or an interest in,
the Depositor or any of its affiliates and are not insured or guaranteed by any
governmental agency. The Certificates are limited in right of payment to certain
collections and recoveries respecting the Loans, all as more specifically set
forth herein and in the Pooling Agreement. To the extent described in the
Pooling Agreement, the Servicer is obligated to advance its own funds to cover
certain shortfalls with respect to payments on the Loans. In the event Servicer
funds are advanced with respect to any Loan, such advance is reimbursable to the
Servicer from the related recoveries on such Loan or from other cash deposited
in the Custodial Account for P&I to the extent that such advance is not
otherwise recoverable.

         As provided in the Pooling Agreement, withdrawals from the Custodial
Account for P&I may be made by the Servicer from time to time for purposes other
than distributions to Certificateholders, such purposes including reimbursement
to the Servicer of advances made, or certain expenses incurred, by it.

         The Pooling Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor and the Servicer, and the rights of the
Certificateholders under the Pooling Agreement at any time by the Depositor and
the Trustee, with the consent of the Holders of the Certificates aggregating not
less than 66-2/3% of the aggregate Percentage Interest evidenced by all of the
Certificates of the Trust Fund. For the purposes of such provision and except as
provided below, voting rights related to 100% of the Aggregate Certificate
Principal Balance of any Class will be allocated pro rata (by Certificate
Principal Balance) among the Certificates of such Class. 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 hereof or in lieu hereof whether or not
notation of such consent is made upon this Certificate. The Pooling 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 Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar or the office maintained by
the Trustee in the City and State of New York, duly endorsed by, or accompanied
by an assignment in the form below or other written instrument of transfer in
form satisfactory to the Trustee or any Authenticating Agent duly executed by,
the Holder hereof or such Holder's attorney duly authorized in writing, and
thereupon one or more new Certificates of Authorized Denominations evidencing
the same Percentage Interest set forth hereinabove will be issued to the
designated transferee or transferees.

         No transfer of a Certificate will be made unless such transfer is
exempt from or is made in accordance with the registration requirements of the
Securities Act of 1933, as amended (the "Securities Act") and any applicable
state securities laws. No transfer, sale, pledge or other disposition of a
Junior Subordinate Certificate shall be made unless such transfer, sale, pledge
or other disposition is made in accordance with Section 5.1(e) or Section 5.1(f)
of the Pooling Agreement. Each Person who, at any time, acquires any ownership
interest in any Junior Subordinate Certificate shall be deemed by the acceptance
or acquisition of such ownership interest to have agreed to be bound by the
provisions of such Section 5.1(e) and Section 5.1(f), as applicable. No transfer
of a Junior Subordinate Certificate shall be deemed to be made in accordance
with such Section 5.1(e) unless such transfer is made pursuant to an effective
registration statement under the Securities Act or unless the Trustee and the
Certificate Registrar are provided with the certificates and an Opinion of
Counsel, if required, on which the Trustee and the Certificate Registrar may
conclusively rely, which establishes or establish to the Trustee's and the
Certificate Registrar's satisfaction that such transfer is exempt from the
registration requirements under the Securities Act, as follows: In the event
that a transfer is to be made in reliance upon an exemption from the Securities
Act, the Trustee and the Certificate Registrar shall require, in order to assure
compliance with the Securities Act, that the Certificateholder desiring to
effect such transfer certify to the Trustee and the Certificate Registrar in
writing, in substantially the form attached as Exhibit F to the Pooling
Agreement, the facts surrounding the transfer, with such modifications to such
Exhibit F as may be appropriate to reflect the actual facts of the proposed
transfer, and that the Certificateholder's proposed transferee certify to the
Trustee and the Certificate Registrar in writing, in substantially the form
attached as Exhibit G to the Pooling Agreement, the facts surrounding the
transfer, with such modifications to such Exhibit G as may be appropriate to
reflect the actual facts of the proposed transfer. If such certificate of the
proposed transferee does not contain substantially the substance of Exhibit G,
the Trustee and the Certificate Registrar shall require an Opinion of Counsel
satisfactory to it that such transfer may be made without registration, which
Opinion of Counsel shall not be obtained at the expense of the Trustee, the
Certificate Registrar, the Trust Fund or the Depositor.

         Transfers of the Junior Subordinate Certificates may also be made in
accordance with Section 5.1(f) of the Pooling Agreement. To effectuate a
Certificate transfer in accordance with such Section 5.1(f), the proposed
transferee of such Certificate must provide the Trustee, the Certificate
Registrar and the Depositor with an investment letter substantially in the form
of Exhibit L attached to the Pooling Agreement, which investment letter shall
not be an expense of the Trustee, the Certificate Registrar or the Depositor,
and which investment letter states that, among other things, such transferee (i)
is a "qualified institutional buyer" as defined under Rule 144A, acting for its
own account or the accounts of other "qualified institutional buyers" as defined
under Rule 144A, and (ii) is aware that the proposed transferor intends to rely
on the exemption from registration requirements under the Securities Act
provided by Rule 144A. Notwithstanding the foregoing, the proposed transferee of
such Certificate shall not be required to provide the Trustee, the Certificate
Registrar or the Depositor with Annex 1 or Annex 2 to the form of such Exhibit L
if the Depositor so consents prior to each such transfer. Such transfers shall
be deemed to have complied with the requirements of Section 5.1(f) of the
Pooling Agreement. The Holder of a Certificate desiring to effect such transfer
does hereby agree to indemnify the Trustee, and the Certificate Registrar, the
Depositor, and the Certificate Registrar

                                      K-5

against any liability that may result if transfer is not made in accordance with
the Pooling Agreement.

         The Certificates are issuable only as registered Certificates without
coupons in Authorized Denominations specified in the Pooling Agreement. As
provided in the Pooling Agreement and subject to certain limitations therein set
forth, Certificates are exchangeable for new Certificates of Authorized
Denominations evidencing the same aggregate interest in the portion of the
Available Distribution Amount distributable on this Class of Certificate, as
requested by the Holder surrendering the same.

         A reasonable service charge may be made for any such registration of
transfer or exchange, and the Trustee or the Certificate Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith.

         The Depositor, the Certificate Registrar, the Servicer, the Trustee and
any agent of any of them may treat the Person in whose name this Certificate is
registered as the owner hereof for all purposes, and neither the Depositor, the
Certificate Registrar, the Servicer, the Trustee nor any such agent shall be
affected by notice to the contrary.

         The respective obligations and responsibilities of the Servicer and the
Trustee created under the Pooling Agreement (other than the obligation to make
payments to Certificateholders as set forth therein) shall terminate upon the
earlier of (i) the later of the final payment or other liquidation (or any
Advance with respect thereto) of the last Loan remaining in the Trust Fund and
the disposition of all property acquired in respect of any Loan or (ii) the
purchase by the Class R Certificateholders of all Loans at a price established
pursuant to the Pooling Agreement; provided, however, that in no event shall the
trust created hereby continue beyond 21 years from the death of the survivor of
certain persons identified in the Pooling Agreement.

                       FORM OF SPECIAL SERVICING AGREEMENT

         This SPECIAL SERVICING AGREEMENT (the "Agreement") is made and entered

identified on Schedule I (the "Class B Holder") and _______________, [an
affiliate of the Class B Holder,] as special servicer (the "Special Servicer").

                              PRELIMINARY STATEMENT

         WHEREAS, the Class B Holder is the holder of at least 75% of each the
classes of Mortgage Pass-Through Certificates (each a "Class B Certificate") of
the series of issuances (each a "Series") issued by the Company identified on
Schedule I attached hereto (such Schedule I, as may be modified or amended to
reflect (i) the purchase from time to time by the Class B Holder of interests in
any class of Class B Certificates of a Series such that the Class B Holder owns
not less than 75% of the then outstanding Certificate Principal Balance of such
Class B Certificates and (ii) the sale from time to time of the Class B Holder
of interests in any class of Class B Certificates of a Series such that the
Class B Holder owns less than 75% of the then outstanding Certificate Principal
Balance of such Class B Certificates, the "Schedule I").

         WHEREAS, each of the Class B Certificates was issued by the Company
pursuant to the Pooling and Servicing Agreement or Agreements (each a "Pooling
and Servicing Agreement") identified on Schedule I and evidences an ownership
interest in a pool of Mortgage Loans.

         WHEREAS, the Company is the Master Servicer of the Mortgage Loans
related to each Series and the Mortgage Loans are serviced in accordance with
the applicable Pooling and Servicing Agreement [and the Company's [Servicer
Guide] (the "Servicer Guide")].

         WHEREAS, in connection with the purchase by Class B Holder of a Series
of Class B Certificates (whether owned by the Class B Holder on the date hereof
or purchased by the Class B Holder at any time in the future), the Class B
Holder and the Company have agreed that (i) the Class B Holder, if it owns 75%
of the most subordinate outstanding class of Class B Certificates of a Series
(calculated by dividing the then outstanding Certificate Principal Balance of
such Class B Certificates by the then outstanding Certificate Principal Balance
of all certificates of the same class) may elect to have certain Mortgage Loans
with respect to the related Series that become 90 or more days delinquent (each
such Mortgage Loan, a "Delinquent Mortgage Loan") serviced by the Special
Servicer (each such Delinquent Mortgage Loan, a "Specially Serviced Mortgage
Loan"), and (ii) with respect to Delinquent Mortgage Loans other than Specially
Serviced Mortgage Loans, the Company will provide to the Class B Holder such
information as is generated [pursuant to the terms of the Servicer Guide] by the
Company or a subservicer with respect to such Delinquent Loan.

         NOW THEREFORE, in consideration of the premises and mutual agreements
hereinafter set forth, the Company, the Class B Holder and the Special Servicer
hereby agree as follows:

                                   ARTICLE I

                                   DEFINITIONS

         Section 1.01 Definitions Incorporated by Reference. Capitalized terms
used but not otherwise defined in this Agreement shall have the respective
meaning ascribed thereto as set forth in the related Pooling and Servicing
Agreement [or the Servicer Guide, as the context may require].

                                   ARTICLE II

          DESIGNATION OF SPECIALLY SERVICED MORTGAGE LOANS AND SPECIAL
                              SERVICING PROCEDURES

         Section 2.02 Specially Serviced Mortgage Loans. To the extent and for
so long as the Class B Certificates of a Series are outstanding and the Class B
Holder owns at least 75% of the most subordinate outstanding class of the Class
B Certificates of such Series (calculated by dividing the then outstanding
Certificate Principal Balance of such Class B Certificates by the then
outstanding Certificate Principal Balance of all certificates of the same
class), Delinquent Mortgage Loans of the related Series may, at the option of
the Class B Holder, be designated in writing by the Class B Holder as Specially
Serviced Mortgage Loans and transferred to the Special Servicer for servicing.
The Special Servicer shall service the Specially Serviced Mortgage Loans in
accordance with the terms of the related Pooling and Servicing Agreement [and
the Servicer Guide].

         Following the designation of a Delinquent Mortgage Loan as a Specially
Serviced Loan, the Company shall transfer servicing of such Delinquent Mortgage
Loan to the Special Servicer substantially in the manner set forth herein and in
Schedule II hereto. [The parties hereto agree that any fees resulting from the
transfer of the servicing of a Delinquent Mortgage Loan from the Company or a
subservicer to the Special Servicer (or any successor thereto) shall be the
obligation of the Company.]

         As of the Effective Date (as defined below) of each Specially Serviced
Mortgage Loan, the Special Servicer shall succeed to and undertake all rights,
duties and obligations of the prior servicer (including, without limitation, the
making of advances, any right to purchase such Specially Serviced Mortgage Loan
at the purchase price set forth in the related Pooling and Servicing Agreement
and the right to receive the servicing fee with respect to such Specially
Serviced Mortgage Loan) pursuant to and in accordance with the terms of the
related Pooling and Servicing Agreement [and the terms and conditions of the
Servicer Guide].

         With respect to each Specially Serviced Mortgage Loan, the effective
date (the "Effective Date") shall be the first day of the month immediately
following the month of designation of such Specially Serviced Mortgage Loan as
such, provided that such written designation is received by the Company on or
prior to the 15th calendar day of such month.

         Once a Delinquent Mortgage Loan becomes a Specially Serviced Mortgage
Loan, such Delinquent Mortgage Loan shall remain a Specially Serviced Mortgage
Loan, and shall continue to be serviced by the Special Servicer, until the
earlier of the liquidation or other disposition of such Specially Serviced
Mortgage Loan or the termination of this Agreement, regardless of delinquency
status, whether the related Mortgaged Property becomes an REO Property or
otherwise; provided, however, that if the Company exercises its right as Master
Servicer to purchase all of the Mortgage Loans in a Trust Fund pursuant to an
optional termination provision under the related Pooling and Servicing
Agreement, the servicing of any related Specially Serviced Mortgage Loans with
respect to which foreclosure proceedings have not been commenced shall be
transferred promptly by the Special Servicer in accordance with written
instructions from the Company.

         If the Class B Holder (i) transfers such percentage interest in any
Class B Certificates of a Series such that the Class B Holder owns less than 75%
of the then outstanding Certificate Principal Balance of such class, or (ii)
purchases such percentage interest in any Class B Certificates of a Series such
that the Class B Holder owns 75% or more of the then outstanding Certificate
Principal Balance of such class, the Class B Holder shall promptly notify the
Company and the Special Servicer in writing of any such transfer or acquisition.
Upon receipt of written notice from the Class B Holder, the Company or the Class
B Holder shall revise Schedule I hereto to reflect any such transfer or
acquisition and shall forward promptly a copy of such revised schedule to the
Company or the Class B Holder, as applicable, and the Special Servicer. With
respect to the purchase of at least 75% of the Class B Certificates of any
Series by the Class B Holder after the date hereof, this Agreement shall be
effective as of the date such written notice of acquisition is received by the
Company.

         If and to the extent the Company is permitted to purchase Delinquent
Mortgage Loans under the related Pooling and Servicing Agreement, the Class B
Holder may direct the Company to purchase any Specially Serviced Mortgage Loan
and to promptly resell such Mortgage Loan to the Class B Holder at the price and
on the terms set forth in such Pooling and Servicing Agreement. In the event the
Class B Holder directs the Company to purchase a Specially Serviced Mortgage
Loan as permitted under this Section, the Company shall promptly take all action
necessary under the terms of the related Pooling and Servicing Agreement in
order to accomplish such purchase (i.e. provide notification to the Trustee
and/or Custodian) and to resell such Specially Serviced Mortgage Loan to the
Class B Holder. The Class B Holder, and not the Company, shall be required to
remit the purchase price for such Specially Serviced Mortgage Loan to the
related Trustee. The Company will inform the Trustee in writing of the purchase
of such Specially Serviced Mortgage Loan by the Class B Holder and further shall
promptly take all actions necessary or desirable to effect the conveyance of
such Mortgage Loan and the related servicing rights to the Class B Holder or its
designee, time being of the essence.

         Notwithstanding any provision herein to the contrary, the Special
Servicer shall (i) in no event be obligated to effect any cure or remedy in
connection with a deficiency in the documentation for any Specially Serviced
Mortgage Loan to the extent such deficiency existed at the time such Mortgage
Loan became a Specially Serviced Mortgage Loan or (ii) have any responsibility
for any obligations, duties, or liabilities of the Company with respect to the
servicing of a Specially Serviced Mortgage Loan that arose prior to the related
Effective Date for such Specially Serviced Mortgage Loan, other than those which
would customarily be assumed after the Effective Date.

         Section 2.03 Termination of Special Servicer for Default. The Company
shall have the right, immediately upon written notice, to terminate the Special
Servicer's right and obligation to subservice all of the Specially Serviced
Mortgage Loans hereunder in the event (each such event, an "Event of Default")
of:

         (i) any failure by the Special Servicer to remit to the Company for
distribution to the Certificateholders of a Series any payment (including
without limitation, any failure to make any required Advance) required to be
made under the terms of this Agreement or the related Pooling and Servicing
Agreement which continues unremedied for a period of one day after the date upon
which written notice of such failure, requiring the same to be remedied, shall
have been given to the Special Servicer by the Company; or

         (ii) any failure on the part of the Special Servicer duly to observe or
perform in any material respect any other of the covenants or agreements on the
part of the Special Sub-Servicer contained in this Agreement (including any
breach of the Special Servicer's representations and warranties contained in
Section 4.03 hereof, which materially and adversely affects the interests of the
Certificateholders of a Series) which continues 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 Special Servicer by the Company; or

         (iii) a decree or order of a court or agency or supervisory authority
having jurisdiction in an involuntary case under any present or future federal
or state bankruptcy, insolvency or similar law or the appointment of a
conservator or receiver or liquidator in any insolvency, readjustment of debt,
marshalling of assets and liabilities or similar proceedings, or for the
winding-up or liquidation of its affairs, shall have been entered against the
Special Servicer and such decree or order shall have remained in force
undischarged or unstayed for a period of 60 consecutive days; or

         (iv) the Special Servicer shall consent 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 Special Servicer or of or relating to all or substantially all of its
property; or

         (v) the Special Servicer shall admit in writing its inability to pay
its debts generally as they become due, file a petition to take advantage of or
otherwise voluntarily commence a case or proceeding under any applicable
bankruptcy, insolvency, reorganization or other similar statute, make an
assignment for the benefit of its creditors, or voluntarily suspend payment of
its obligations.

         If an Event of Default shall occur, then, and in each and every such
case, upon receipt of written notice from the Company, the Special Servicer
shall immediately remit to the Company all amounts in the Collection Accounts
and the Escrow Accounts and all rights of the Special Servicer to service the
Specially Serviced Mortgage Loans shall terminate. Following the receipt of
written notice from the Company as provided above, all authority and power of
the Special Sub-Servicer to subservice all the Specially Serviced Mortgage Loans
shall pass to and be vested in the Company pursuant to and under this Section
2.03, and the Special Servicer shall do all things necessary to effect a
transfer of the servicing rights back to the Company. In this regard, the
Company is hereby authorized and empowered to execute and deliver, on behalf of
the Special Servicer, as attorney-in-fact or otherwise, any and all documents
and other instruments, and to do or accomplish all other acts or things

         Section 3.01 Reporting of Delinquent Mortgage Loans.

         (a) To the extent and for so long as the Class B Certificates of a

         Mortgage Loan, the (i) Principal Balance of each such Mortgage Loan

         (b) If requested by the Class B Holder, the Company shall make its
servicing personnel available to respond to reasonable inquiries, by phone or in
writing by facsimile, electronic, or overnight mail transmission, in connection
with any Mortgage Loan identified in any report or document provided pursuant to
clause (a) above; provided, that the Company shall only be required to provide
information that is reasonably accessible to its servicing personnel (or its
subservicers).

         (c) In addition to the information described above, the Company shall
provide to the Class B Holder such information as the Class B Holder may
reasonably request; provided, however, that the Mortgage Loans are Delinquent
Mortgage Loans or the Mortgaged Property has been foreclosed upon. The Class B
Holder will reimburse the Company for any reasonable out-of-pocket expenses
incurred by it in providing such information.

         Section 3.02 Servicing of Delinquent Mortgage Loans.

         (a) Prior to the Commencement of Foreclosure of any Mortgage Loan, the
Company shall provide, or cause the related servicer to provide, the Class B
Holder with a notice (sent by telecopier) of such proposed and imminent
foreclosure, stating the loan number and the aggregate amount due under the
Mortgage Note.

         For purposes of this Agreement, "Commencement of Foreclosure" shall
mean the first official action required under local law in order to commence
foreclosure proceedings or to schedule a trustee's sale under a deed of trust,
including (i) in the case of a mortgage, any filing or service of process
necessary to commence an action to foreclosure, or (ii) in the case of a deed of
trust, posting, the publishing, filing or delivery of a notice of sale, but not
including in either case (x) any notice of default, notice of intent to
foreclose or sell or any other action prerequisite to the actions specified in
(i) or (ii) above, (y) the acceptance of a deed-in-lieu of foreclosure (whether
in connection with a sale of the related property or otherwise) or (z)
initiation and completion of a short pay-off.

         (b) In connection with any Delinquent Mortgage Loan with respect to
which a notice under clause (a) above has been delivered to the Class B Holder,
the Class B Holder shall provide the Company with written direction as to the
action to be taken with respect to such Delinquent Mortgage Loan, including,
without limitation, to proceed with foreclosure, to accept a deed-in-lieu of
foreclosure, to consent to a pre-foreclosure sale of Mortgaged Property at a
loss, or, if permitted under the terms of the related Pooling and Servicing
Agreement, to purchase Delinquent Mortgage Loans. Such written direction must be
received by the Company within two (2) Business Days of transmission of the
notice provided by the Company under clause (a) above. Such two (2) Business Day
period shall be extended for no longer than an additional three (3) Business
Days after the receipt of additional information requested if the Class B Holder
requests additional information related to such Delinquent Mortgage Loan;
provided, however that the Class B Holder will have at least one Business Day to
provide written direction after receipt of any requested additional information.
Any such additional information shall be provided only to the extent it is
obtainable by the Company from existing reports, certificates or statements or
otherwise be reasonably accessible to its servicing personnel (or subservicing
personnel). The Company shall as promptly as practicable carry out, or cause the
relevant servicer to carry out, the instruction of the Class B Holder in the
manner prescribed in such written direction. The Class B Holder agrees that it
has no right to negotiate directly with the Mortgagor during such period.

         In the event the Class B Holder fails to provide any written direction
as provided above, the Company may take any such action as would be consistent
with customary servicing practices of prudent mortgage loan servicers and the
Company's normal policies and practice.

         (c) With respect to any Delinquent Mortgage Loan for which the Company
has not provided a notice as contemplated in clause (a) above, the Class B
Holder may, at any time, provide the Company with written direction as to the
action to be taken with respect to such Delinquent Mortgage Loan, including,
without limitation, to commence foreclosure proceedings, to accept a
deed-in-lieu of foreclosure, to consent to a sale of Mortgaged Property at a
loss, or, if permitted under the terms of the related Pooling and Servicing
Agreement, to purchase Delinquent Mortgage Loans. To the extent such action is
not inconsistent with the terms of the related Pooling and Servicing Agreement
or the Company's duties thereunder as master servicer, the Company shall as
promptly as practicable carry out, or cause the relevant servicer to carry out,
the instruction of the Class B Holder in the manner prescribed in such written
direction.

         (d) Any foreclosure of a Delinquent Mortgage Loan that has been
initiated in accordance with clauses (b) or (c) above may be discontinued if (i)
the Mortgage Loan has been brought current or if a refinancing or prepayment
occurs with respect to the Mortgage Loan (including by means of a short payoff
approved by the Class B Holder), (ii) the Company has agreed to the terms of a
forbearance agreement with the Mortgagor and such forbearance agreement has been
approved by the Class B Holder, or (iii) if and to the extent permitted under
the related Pooling and Servicing Agreement, Class B Holder directs the Company
to purchase such Delinquent Mortgage Loan at the price and on the terms set
forth in the related Pooling and Servicing Agreement.

         (e) In the event the Class B Holder directs the Company to purchase a
Delinquent Mortgage Loan as permitted under Sections 2.02 and 3.02 (b), (c) and
(d), the Class B Holder may direct the Company to purchase any Delinquent
Mortgage Loan and to promptly resell such Mortgage Loan to the Class B Holder at
the price and on the terms set forth in the applicable Pooling and Servicing
Agreement. In the event the Class B Holder directs the Company to purchase a
Delinquent Mortgage Loan as permitted under this Section, the Company shall
promptly take all action necessary under the terms of the related Pooling and
Servicing Agreement in order to accomplish such purchase (i.e. provide
notification to the Trustee and/or Custodian) and to resell such Delinquent
Mortgage Loan to the Class B Holder. The Class B Holder, and not the Company,
shall be required to remit the purchase price for such Delinquent Mortgage Loan
to the related Trustee. The Company will inform the Trustee in writing of the
purchase of such Delinquent Mortgage Loan by the Class B Holder and further
shall promptly take all actions necessary or desirable to effect the conveyance
of such Mortgage Loan and the related servicing rights to the Class B Holder or
its designee, time being of the essence. [The parties hereto agree that, in
connection with a purchase of a Delinquent Mortgage Loan as provided above, any
fees resulting from the transfer of the servicing of such purchased Delinquent
Mortgage Loan from the Company or a subservicer to a servicer designated by the
Class B Holder shall be the obligation of the Company.]

         Section 3.03 Review of the Company's Procedures. The Company and the
Class B Holder hereby agree that the Class B Holder shall have the right, at its
own expense and during normal business hours, to review any and all of the
books, records, or other information of the Company which may be relevant to the
Company's direct collection, loss mitigation foreclosure and REO management
procedures currently in place in order to confirm that the procedures used by
the Company and its subservicers are in accordance with the customary servicing
practices of prudent mortgage loan servicers. In order to discuss such books,
records or other information, the Company shall make personnel available who are
knowledgeable about such matters.

duly organized, validly existing, and in good standing under the laws of its
state of incorporation or formation or the laws of the United States.

         (ii) No Violation. Neither the execution and delivery by the Class B
Holder of this Agreement, nor the consummation by the Class B Holder of the
transactions contemplated hereby, nor the performance of and compliance by the
Class B Holder with the provisions of this Agreement, will conflict with or
result in a breach or violation of, or constitute a default (or an event which,
with notice or the lapse of time, or both, would constitute a default) under,
the organizational documents (its articles of incorporation or charter or
by-laws) of the Class B Holder, or any of the provisions of any law, rule,
regulation, judgment, decree, demand, or order (of any federal, state, or local
governmental or regulatory authority or court) binding on the Class B Holder, or
any of its respective properties, or any of the provisions of any indenture,
mortgage, contract, instrument, or other document to which the Class B Holder is
a party or by which it is bound, or result in the creation or imposition of any
lien, charge, or encumbrance upon any of their respective properties pursuant to
the terms of any indenture, mortgage, contract, instrument, or other document.
The Class B Holder is not otherwise in violation of any law, rule, regulation,
judgment, decree, demand, or order (of any federal, state or local governmental
or regulatory authority or court), which violation, in the Class B Holder's,
good faith and reasonable judgment, is likely to affect materially and adversely
its ability to perform its obligations hereunder.

         (iii) Authorization and Enforceability. The execution and delivery by
the Class B Holder of this Agreement, the consummation of the transactions
contemplated hereby, and the performance and compliance by the Class B Holder

Holder, enforceable against it in accordance with its terms, subject to
applicable bankruptcy, insolvency, reorganization, moratorium, and other similar
laws affecting creditors' rights generally, and to general principles of equity,
regardless of whether such enforcement is considered in a proceeding in equity
or at law. The Class B Holder has not failed to obtain any consent, approval,
authorization, or order of, or failed to cause any registration or qualification
with, any court or regulatory authority or other governmental body having
jurisdiction over it, which consent, approval, authorization, order,
registration, or qualification is required for, and the absence of which would
materially adversely affect, the legal and valid execution, delivery, and
performance of this Agreement by the Class B Holder.

         (iv) No Litigation or Adverse Conditions. No litigation is pending or,
to the best of the Class B Holder's knowledge, threatened against it, which, if
determined adversely to the Class B Holder would prohibit the Class B Holder

                        Mortgage Loan Purchase Agreement

                  Mortgage Loan Purchase Agreement (the "Agreement"), dated as
of April 27, 2001 between Washington Mutual Mortgage Securities Corp. (the
"Seller") and ABN AMRO Mortgage Corporation (the "Purchaser").

                  Subject to the terms and conditions of this Agreement, the
Seller agrees to sell and the Purchaser agrees to purchase certain mortgage
loans (the "Mortgage Loans") as described herein and as identified on the
Mortgage Loan Schedule defined in Section 2 hereof. The Mortgage Loans will be
purchased on a servicing released basis.

                  Now, therefore, in consideration of the premises and the
mutual agreements set forth herein, the parties agree as follows:

         SECTION 1. Purchase and Sale of the Mortgage Loans.

         (a) Pursuant to the terms hereof and upon satisfaction of the
conditions set forth herein, the Seller agrees to sell and the Purchaser agrees
to purchase, Mortgage Loans having the general characteristics set forth in this
Agreement and specifically identified on the Mortgage Loan Schedule, for the
Purchase Price set forth below in Section 3(a) hereof and having an aggregate
principal balance on and as of the date of such Mortgage Loan Schedule (the
"Cut-Off Date") of approximately $237,316,463.23 after deduction of principal
payments due on or before the Cut-Off Date (which amount may vary plus or minus
5% thereof), or such other aggregate principal balance as agreed by the
Purchaser and the Seller as evidenced by the actual aggregate principal balance
of the Mortgage Loans accepted by the Purchaser on the Closing Date (as defined
below).

         (b) Subject to mutual agreement between the Purchaser and the Seller,
the closing for the purchase and sale of the Mortgage Loans shall take place on
April 27, 2001 (the "Closing Date") at the office of Purchaser's counsel in
Chicago, Illinois or such other place as the parties shall agree.

         SECTION 2. Mortgage Loan Schedule. Attached to this Agreement as
Schedule 1 is a listing of the Mortgage Loans evidenced by promissory notes,
mortgage notes or other evidence of indebtedness (the "Mortgage Notes")
evidencing the indebtedness of an obligor (the "Mortgagor") under the mortgages,
deeds of trust or other instruments securing a Mortgage Loan (the "Mortgages")
to be purchased by and delivered to the Purchaser on the Closing Date (as such
may be amended prior to the Closing Date by mutual agreement of the parties)
(the "Mortgage Loan Schedule"). The "Mortgage Loan Schedule" as of the Closing
Date shall refer to the Mortgage Loan Schedule as delivered on the Cut-Off Date
related to such Mortgage Loans to be purchased by or on behalf of the Purchaser
pursuant to the terms of this Agreement. The Mortgage Loan Schedule shall
contain as to each Mortgage Loan listed thereon, at a minimum, the Mortgage Loan
information indicated on Schedule 2 hereto.

<PAGE>

         SECTION 3. Purchase Price.

         (a) In exchange for the Mortgage Loans, on the Closing Date, the
Purchaser shall transfer to the Seller by wire transfer in immediately available
funds the purchase price (the "Purchase Price") which is equal to the sum of (a)
the product of 101.119952% and the principal balance thereof as of the Cut-Off
Date and (b) interest on the principal balance of the Mortgage Loans as of the
Cut-Off Date at the Pass-Through Rate from the Cut-Off Date through the day
prior to the Closing Date. With respect to each Mortgage Loan, the "Pass-Through
Rate" shall be the mortgage interest rate on such Mortgage Loan less the per
annum servicing fee payable to the Seller pursuant to the Pooling Agreement (as
defined below).

         (b) The Purchaser shall be entitled to all scheduled payments of
principal and interest due with respect to the Mortgage Loans after the Cut-Off
Date, and all other recoveries of principal and interest collected after the
Cut-Off Date (other than in respect of principal and interest on the Mortgage
Loans due on or before the Cut-Off Date). The Seller shall be entitled to all
scheduled payments of principal and interest due with respect to the Mortgage
Loans on or before the Cut-Off Date, and all other recoveries of principal and
interest collected on or before the Cut-Off Date (other than in respect of
principal and interest on the Mortgage Loans due after the Cut-Off Date). The
principal balance of each Mortgage Loan as of the Cut-Off Date is determined
after deduction of payments of principal due on or before the Cut-Off Date
whether or not collected. Therefore, payments of scheduled principal and
interest prepaid for a date due following the Cut-Off Date shall not be deducted
from the principal balance as of the Cut-Off Date but such prepaid amounts shall
belong to and be promptly remitted to the Purchaser.

         SECTION 4. Examination of Mortgage Files.

         Prior to the Closing Date, the Seller will have made files for each
Mortgage Loan, that consist at least of the documents listed on Schedule 3
attached hereto (with respect to each Mortgage Loan, a "Mortgage File", and
collectively, the "Mortgage Files"), available to the Purchaser or its agents,
for examination at the Seller's offices or such other location as shall
otherwise be agreed upon by the Purchaser and the Seller. The Purchaser may
purchase all or part of the Mortgage Loans with or without conducting any
partial or complete examination. The fact that the Purchaser or its agents have
conducted or have failed to conduct any partial or complete examination of the
Mortgage Files shall not affect the Purchaser's rights under this Agreement,
including, but not limited to, the rights to demand repurchase, substitution or
other relief as provided in this Agreement.

         SECTION 5.    Transfer of Mortgage Loans; Possession of Mortgage Files.

         (a) On the Closing Date, subject to the satisfaction of the terms and
conditions hereof, the Seller shall sell, transfer, assign, set over and
otherwise convey to the Purchaser, without recourse, but subject to the terms of
this Agreement, all right, title and interest of the Seller in and to the
Mortgage Loans and all proceeds thereof, wherever located, including without
limitation, all amounts in respect of principal and interest received or
receivable with respect to Mortgage Loan

                                       -2-

payments due after the Cut-Off Date (and including scheduled payments of
principal and interest due after the Cut-Off Date but received by the Seller on
or before the Cut-Off Date, but not including payments of principal and interest
due on the Mortgage Loans on or before the Cut-Off Date), together with the
proceeds of any related mortgage insurance policies. Such transfer shall be made
directly to the Purchaser in accordance with the letter delivered to the Seller
by the Purchaser attached hereto as Exhibit A (the "Instruction Letter"). The
Seller's records will accurately reflect the sale of each Mortgage Loan to the
Purchaser.

         (b) The ownership of each Mortgage Loan and the related Mortgage Note,
the Mortgage and the contents of the related Mortgage File shall be, upon
satisfaction of subsection 5(a) hereof, vested in the Purchaser and the
ownership of all records and documents with respect to such Mortgage Loan
prepared by or which come into the possession of the Seller shall immediately
vest in the Purchaser and shall be retained and maintained by the Seller at the
will and for the benefit of the Purchaser in a custodial capacity only. The
Seller shall deliver to the Purchaser or its agent in accordance with the
instructions set forth in Exhibit A, simultaneously with the execution and
delivery of this Agreement or prior to the Closing Date, all of the documents
pertaining to each Mortgage Loan previously delivered to the Seller by ABN AMRO
Mortgage Group, Inc. ("AAMGI") pursuant to that certain Mortgage Loan Purchase
Agreement, dated as of April 17, 2001, between the Seller, as purchaser, and
AAMGI, as seller.

         (c) The transfer of the Mortgage Loans as described herein shall be
absolute and is intended by the parties to be a sale. In the event that a court
deems the conveyance set forth herein not to constitute a sale, the Seller shall
have granted to the Purchaser a first priority security interest in the Mortgage
Loans and in the proceeds thereof of any kind or nature whatsoever, and in the
proceeds of any related insurance policies, subject to the satisfaction or
waiver of the conditions set forth in Section 11 hereof, and shall take, or
shall cause to have been taken, all steps necessary prior to the Closing Date to
perfect such security interest in the Purchaser.

         SECTION 6. Books and Records.

         On the Closing Date, following the sale of the Mortgage Loans to the
Purchaser, title to each Mortgage and the related Mortgage Note shall be
transferred to the Purchaser or its assignee in accordance with this Agreement.
All rights arising out of the Mortgage Loans after the Cut-Off Date including,
but not limited to, any and all funds received on or in connection with a
Mortgage Loan and due after the Cut-Off Date shall be received and held by the
Seller in a custodial capacity for the benefit of the Purchaser or its assignee
as the owner of the Mortgage Loans in accordance herewith and shall be delivered
or caused to be delivered by the Seller to the Purchaser or its assignee on or
immediately following the Closing Date. Any funds received by the Seller or the
Purchaser after the Cut-Off Date but due prior to the Cut-Off Date shall remain
the property of the Seller and shall be promptly remitted to the Seller. As
additional consideration for the Mortgage Loans, the Purchaser shall enter into,
and shall cause State Street Bank and Trust Company, as trustee, to enter into,
a Pooling and Servicing Agreement (the "Pooling Agreement") with the Seller,
which Pooling Agreement shall be reasonably satisfactory to the Seller in form
and substance, pursuant to which

                                       -3-

<PAGE>

the Seller shall have the right to service each Mortgage Loan for a servicing
fee ranging from 0.29% to 0.99% per annum, with a weighted average of 0.7895%
per annum. The Pooling Agreement shall be executed simultaneously with the
execution of this Agreement.

         SECTION 7. Further Actions; Financing Statements.

         (a) In furtherance of the provisions of Section 5(c) hereof, the Seller
agrees to take or cause to be taken such further actions to execute, deliver and
file or cause to be executed, delivered and filed, such further documents and
instruments (including, without limitation, any UCC financing statements) as the
Purchaser may reasonably request, in order to perfect and maintain the security
interest created pursuant to said section and to otherwise fully effectuate the
purposes, terms and conditions of this Agreement, and the Purchaser shall
cooperate in any such action.

         (b) The Seller shall: (i) promptly execute, deliver, and file any
financing statements, amendments, continuation statements, assignments,
certificates and other documents with respect to such security interest as the
Purchaser may reasonably request to perfect or to maintain the perfection of
such security interest, each in form and substance satisfactory to the
Purchaser; and (ii) notify the Purchaser within five (5) days after the

name or any trade name; (B) any change in the Seller's location of its chief

                  as described in subclause (A)(i) or (A)(ii) above;

                           (t) each Mortgage Loan is a "qualified mortgage"
                  within the meaning of Section 860G of the Internal Revenue
                  Code of 1986, without regard to ss.1.860 G-2(f) of the REMIC
                  provisions or any similar rule;

                           (u) each Mortgage Loan that has a Loan-to-Value Ratio
                  at origination in excess of 80% is covered by a primary
                  mortgage insurance policy; and

                           (v) that no Mortgage Loan permits negative
                  amortization or the deferral of accrued interest.

                  It is understood and agreed that the representations and
         warranties set forth in this Section 8 shall survive the sale of the
         Mortgage Loans to the Purchaser and shall inure to the benefit of the
         Purchaser, notwithstanding any restrictive or qualified endorsement on
         any Mortgage Note (or lost note affidavit and indemnity) or assignment
         of Mortgage or the examination of any Mortgage File.

                  Upon discovery by either the Seller, the Purchaser or its
         designees of a breach of any of the foregoing representations or
         warranties of the Seller which materially and adversely affects (1) the
         value of any of the Mortgage Loans actually delivered or (2) the
         interests of the Purchaser therein, the party discovering such breach
         shall give prompt written notice to the other. Within 90 (ninety) days
         of its discovery or its receipt of notice of any such breach of a
         representation or warranty, the Seller shall, with respect to the
         Mortgage Loan(s) to which such breach relates, either (i) cure such
         breach in all material respects, (ii) repurchase such Mortgage Loan or
         Mortgage Loans (or any property acquired in respect thereof) from the
         Purchaser at the Purchase Price, as adjusted for the then current
         principal balance or (iii) within the 90 (ninety)-day period following
         the Closing Date substitute another mortgage loan for such Mortgage
         Loan. Such substitute mortgage loan shall on the date of substitution,
         (a) have a principal balance not in excess of the principal balance of
         the defective Mortgage Loan, (b) be accruing interest at a rate of
         interest at least equal to that of the defective Mortgage Loan, (c)
         have a remaining term to stated maturity not greater than, and not more
         than two years less than, that of the Mortgage Loan so substituted, (d)
         have an original loan-to-value ratio not higher than that of the
         Mortgage Loan so substituted and a current loan-to-value ratio not
         higher than that of the Mortgage Loan so substituted, and (e) comply
         with all the representations and warranties relating to Mortgage Loans
         set forth herein, as of the date of substitution (such mortgage loan
         being referred to herein as a "Qualifying Substitute Mortgage Loan").
         Except as set forth in Section 12 hereof, it is understood and agreed
         that the obligations of the Seller set forth in this Section 8 to cure,
         substitute for or repurchase a defective Mortgage Loan constitute the
         sole remedies of the Purchaser respecting a breach of the foregoing
         representations and warranties.

                  The Purchaser, upon receipt by it of the full amount of the
         then current principal balance for a Mortgage Loan that is repurchased,
         or upon receipt of the Mortgage File for a Qualifying Substitute
         Mortgage Loan for a Mortgage Loan that is substituted or repurchased,
         shall release or cause to be released and reassign to the Seller the
         related Mortgage File for the Mortgage Loan that is substituted and
         shall execute and deliver such instruments of transfer or assignment,
         in each case without recourse, representation, or warranty, as shall be
         necessary to vest in the Seller or its designee or assignee title to
         any such substituted Mortgage Loan released pursuant hereto or Mortgage
         Loan purchased pursuant hereto, free and clear of all security
         interests, liens and other encumbrances, which instruments shall be
         prepared by the Seller at its expense and shall be reasonably
         acceptable to the Purchaser, and the Purchaser shall have no further
         responsibility with respect to the Mortgage File relating to such
         Mortgage Loan that is substituted.

                  Any cause of action against the Seller or relating to or
         arising out of the breach of any representations and warranties made in
         this Section 8 shall accrue as to any Mortgage Loan upon (i) discovery
         of such breach by the Purchaser or notice thereof by the Seller to the
         Purchaser, (ii) failure by the Seller to cure such breach, repurchase
         such Mortgage Loan or substitute a Qualifying Substitute Mortgage Loan
         as specified above, and (iii) demand upon the Seller by the Purchaser
         for all amounts payable in respect of such Mortgage Loan.

         provisions of, or constitute a default under, any indenture, mortgage,
         deed of trust, loan agreement or other material agreement or instrument
         to which the Purchaser is a party or by which the Purchaser or to which
         any property or assets of the Purchaser is subject;

                  (iii) This Agreement, assuming due authorization, execution
         and delivery by the Seller, constitutes a valid and legally binding
         obligation of the Purchaser, enforceable against the Purchaser in
         accordance with its terms, subject, as to enforcement, to bankruptcy,
         insolvency, reorganization and other similar laws of general
         applicability relating to or affecting creditors' rights and to general
         equity principles, regardless of whether such enforcement is considered
         in a proceeding in equity or at law;

         or decree of any court or any order, regulation or demand of any
         federal, state, municipal or governmental agency, which the Purchaser
         default might have consequences that would materially and adversely
         affect the condition (financial or other) or operations of the
         Purchaser or its properties or might have consequences that would
         affect its performance hereunder; and

                  (v) No litigation is pending or, to the best of the
         Purchaser's knowledge, threatened against the Purchaser which would
         prohibit its entering into this Agreement or performing its obligations
         under this Agreement;

         (c) The Seller will furnish to the Purchaser such other certificates of

against any and all losses, claims, expenses, damages or liabilities to which
Purchaser may become subject, insofar as such losses, claims, expenses, damages
or liabilities (or actions in respect thereof) arise out of or are

                                      -11-

<PAGE>

based upon any representation or warranty made by the Seller in Section 8(a)(i)
through Section 8(a)(vi) hereof on which Purchaser has relied, being, or alleged
to be, materially untrue or incorrect. This indemnity will be in addition to any
liability which the Seller may otherwise have.

         (b) The Purchaser agrees to indemnify and hold harmless the Seller
solely in its capacity as seller of the Mortgage Loans against any and all
losses, claims, expenses, damages or liabilities to which the Seller may become
subject, insofar as such losses, claims, expenses, damages or liabilities (or
actions in respect thereof) arise out of or are based upon any representation or
warranty made by the Purchaser in Section 9 hereof on which the Seller has
relied, being, or alleged to be, materially untrue or incorrect (notwithstanding
the Purchaser's lack of knowledge with respect to the substance of any
representation or warranty to which Section 9 applies which is made to the best
of the Purchaser's knowledge). This indemnity will be in addition to any
liability which the Purchaser may otherwise have.

         (c) Promptly after receipt by either the Purchasers or the Seller of
notice of the commencement of any action or proceeding in any way relating to or
arising from this Agreement, such party will notify the other party of the
commencement thereof; but the omission so to notify the party from whom
indemnification is sought (the "Indemnifying Party") will not relieve the
Indemnifying Party from any liability which it may have to the party seeking
indemnification (the "Indemnified Party") except to the extent that the
Indemnifying Party is adversely affected by the lack of notice. In case any such
action is brought against the Indemnified Party, and it notifies the
Indemnifying Party of the commencement thereof, the Indemnifying Party will be
entitled to participate in the defense (with the consent of the Indemnified
Party which shall not be unreasonably withheld) of such action at the
Indemnifying Party's expense.

         SECTION 13. Notices. All demands, notices and communications hereunder

mutual consent of the parties hereto, or (b) by the Purchaser if the conditions
to the Purchaser's obligations to closing set forth under Section 10 hereof are
not fulfilled as and when required to be fulfilled or (c) by the Seller if the
Purchaser's obligations under Section 11 hereof are not fulfilled as and when
required. In the event of a termination pursuant to Section 14(b), the Seller
agrees that it will pay the out-of-pocket fees and expenses of the Purchaser in
connection with the transactions contemplated by this Agreement and in the event
of a termination pursuant to Section 14(c), the Purchaser agrees that it

                                      -12-

will pay the out-of-pocket fees and expenses of the Seller in connection with
the transactions contemplated by this Agreement.

         SECTION 15. Representations, Warranties and Agreements to Survive

Agreement, or in certificates of officers of the Seller and the Purchaser
submitted pursuant hereto, shall remain operative and in full force and effect
and shall survive transfer and sale of the Mortgage Loans to the Purchaser.

         SECTION 16. Severability. If any provision of this Agreement shall be
prohibited or invalid under applicable law, the Agreement shall be ineffective
only to such extent, without invalidating the remainder of this Agreement.

         SECTION 17. Counterparts. This Agreement may be executed in any number
of counterparts, each of which shall be an original, but both of which together
shall constitute one and the same agreement.

made in the State of New York and shall be interpreted in accordance with the
laws of such state without regard to the principles of conflicts of law of such
state.

         SECTION 19. Further Assurances. The Seller and the Purchaser agree to
execute and deliver such instruments and take such actions as the other party
may, from time to time, reasonably request in order to effectuate the purpose
and to carry out the terms of this Agreement.

         SECTION 20. Successors and Assigns. This Agreement shall be binding
upon and inure to the benefit of and be enforceable by the Seller and the
Purchaser and their permitted successors and assigns. The Seller acknowledges
and agrees that the Purchaser may assign its rights under this Agreement. Any
person into which the Seller may be merged or consolidated (or any person
resulting from any merger or consolidation involving the Seller), or any person
succeeding to the business of the Seller shall be considered the "successor" of
the Seller hereunder. Except as provided in the two preceding sentences, this
Agreement cannot be assigned, pledged or hypothecated by any party hereto
without the written consent of the other party to this Agreement.
Notwithstanding anything to the contrary in this Section 20, the parties hereto
agree that the Purchaser has the right to assign its rights and interest in, to
and under Section 8 hereof.

         SECTION 21. Amendments. No term or provision of this Agreement may be
waived or modified unless such waiver or modification is in writing and signed
by a duly authorized officer of the party against whom such waiver or
modification is sought to be enforced.

                  where such original Mortgage has been delivered for
                  recordation or because such original Mortgage has been lost,
                  the Seller shall deliver or cause to be delivered to the
                  Purchaser (with a copy to the Trustee (as defined in the

                  such Mortgage, together with (1) in the case of a delay caused
                  by the public recording office, a certificate signed by an
                  Authorized Officer of the Seller stating that such original
                  Mortgage has been dispatched to the appropriate public
                  recording official for recordation or (2) in the case of an
                  original Mortgage that has been lost, a certificate by the
                  appropriate county recording office where such Mortgage is
                  recorded or from a title insurance company or escrow company
                  indicating that such original was lost and the copy of the
                  original mortgage is a true and correct copy;

                  (b) the original assignment to "State Street Bank and Trust

                  Seller as a true and correct copy of the original assignment
                  which has been sent for recordation. Subject to the foregoing,
                  such assignments may, if permitted by law, be by blanket
                  assignments for Mortgage Loans covering Mortgaged Properties
                  situated within the same county. If the assignment is in

         Re: ABN AMRO Mortgage Corporation Purchase of Mortgage Loans

Ladies and Gentlemen:

         As General Counsel to Washington Mutual Mortgage Securities Corp., a
Delaware Corporation ("Seller"), I and attorneys working under my supervision
have acted as counsel to Seller in connection with the sale of Mortgage Loans by
Seller to ABN AMRO Mortgage Corporation (the "Purchaser") pursuant to a Mortgage
Loan Purchase Agreement, dated as of April 27, 2001 (the "Purchase Agreement"),
between the Purchaser and Seller. This opinion is being delivered to the
Purchaser pursuant to Section 10(b)(iv) of the Purchase Agreement. All
capitalized terms not otherwise defined herein have the meanings given them in
the Purchase Agreement.

         In rendering the opinions set forth below, we have examined and relied
upon originals or copies, certified or otherwise identified to our satisfaction,
of the charter and by-laws of Seller, the Purchase Agreement and such corporate
records, agreements or other instruments of Seller, and such certificates,
records and other documents, agreements and instruments, including, among other
things, certain documents delivered on the Closing Date, as we have deemed
necessary and proper as the basis for our opinions. In connection with such
examination, we have assumed the genuineness of all signatures, the authenticity
of all documents, agreements and instruments submitted to us as originals, the
conformity to original documents, agreements and instruments of all documents,
agreements and instruments submitted to us as copies or specimens, the
authenticity of the originals of such documents, agreements and instruments
submitted to us as copies or specimens, the conformity to executed original
documents of all documents submitted to us in draft and the accuracy of the
matters set forth in the documents we reviewed. We have also assumed that all
documents, agreements and instruments have been duly authorized, executed and
delivered by all parties thereto. As to any facts material to such opinions that
we did not independently establish

<PAGE>

ABN AMRO Mortgage Corporation
__________ __, 200_
Page 2

or verify, we have relied upon statements and representations of officers and
other representatives of Seller as we have deemed necessary and proper as the
basis for our opinions, including, among other things, the representations and
warranties of Seller in the Purchase Agreement.

         Based upon the foregoing, I am of the opinion that:

         1. Seller is a ______________, duly organized, validly existing and in
good standing under the laws of _____________ and either is not required to be
qualified to do business under the laws of any states where such qualification
is necessary to transact the business contemplated by the Purchase Agreement, or
is qualified to do business under the laws of any states where such
qualification is necessary to transact the business contemplated by the Purchase
Agreement, and Seller is duly authorized and has full corporate power and
authority to transact the business contemplated by the Purchase Agreement.

         2. The Purchase Agreement has been duly authorized, executed and
delivered by Seller and is a legal, valid and binding obligation of and is
enforceable against Seller in accordance with its terms, except that the
enforceability thereof may be subject to (A) bankruptcy, insolvency,
receivership, conservatorship, reorganization, moratorium or other laws, now or
hereafter in effect, relating to creditors' rights generally, (B) general
principles of equity (regardless of whether enforcement is sought in a
proceeding in equity or at law) and (C) limitations of public policy under
applicable securities laws as to rights of indemnity and contribution under the
Purchase Agreement.

         3. No consent, approval, authorization or order of any court or
supervisory, regulatory, administrative or governmental agency or body is
required for the execution, delivery and performance by Seller of or compliance
by Seller with the Purchase Agreement, the sale of the Mortgage Loans or the
consummation of the transactions contemplated by the Purchase Agreement.

         4. Neither the execution and delivery by Seller of the Purchase
Agreement, nor the consummation by Seller of the transactions contemplated
therein, nor the compliance by Seller with the provisions thereof, will conflict
with or result in a breach of any of the terms, conditions or provisions of
Seller's charter or by-laws or board or shareholder's resolutions, or any
agreement or instrument to which Seller is now a party or by which it is bound,
or constitute a default or result in an acceleration under any of the foregoing,
or result in the violation of any law, rule, regulation, order, judgment or
decree to which Seller or its property is subject, which, in any of the above
cases, would materially and adversely affect Seller's ability to perform its
obligations under the Purchase Agreement.

         5. There is not an action, suit, proceeding or investigation pending,
or, to the best of my knowledge, threatened against Seller which, either in any
one instance or in the aggregate, would

<PAGE>

__________ __, 200_
Page 3

draw into question the validity of the Purchase Agreement or the Mortgage Loans
or of any action taken or to be taken in connection with the obligations of
Seller contemplated therein, or which would be likely to materially impair the
ability of Seller to perform under the terms of the Purchase Agreement.
