         This Pooling and Servicing Agreement, dated and effective as of May 1,
2003 (this "Agreement"), is executed by and among ABN AMRO Mortgage Corporation,
as depositor (the "Depositor"), ABN AMRO Mortgage Group, Inc., as a servicer
("AAMG"), Washington Mutual Mortgage Securities Corp., as a servicer ("WMMSC"
and together with AAMG, the "Servicers"), and JPMorgan Chase Bank, 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
Servicers 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 Servicers 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 January 23, 2003, and a Prospectus Supplement, dated May 27, 2003 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 May 28, 2003. 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 Group I 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 Certificate 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 Group II 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 II." Component R-2
of the Class R Certificate will represent the sole class of "residual interest"
in REMIC II 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 and REMIC II Regular
Interests as a REMIC for federal income tax

purposes, and such segregated pool of assets will be designated as "REMIC III".
Component R-3 of the Class R Certificate will represent the sole class of
"residual interests" in REMIC III for purposes of the REMIC Provisions under
federal income tax law. The following table irrevocably sets forth the
designations, the Remittance Rate, initial Class Principal Balance and Last

Regular Interests, REMIC II 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,
as of the Closing Date, the longest remaining amortization schedule,
irrespective of its scheduled maturity.

                                        +
           4.729954229% multiplied by the Group II Subordinate Amount
           ----------------------------------------------------------
            Group I Subordinate Amount + Group II Subordinate Amount

         SUBORDINATE LIQUIDATION AMOUNT: For each Loan Group, the excess, if
any, of the aggregate of Liquidation Principal for all Loans which became
Liquidated Loans during the Prepayment Period, over the related Senior
Liquidation Amount for such Distribution Date.

         SUBORDINATE PERCENTAGE: As of the Closing Date, as determined
separately for each Loan Group, approximately 2.26% for Loan Group I and 2.26%
for Loan Group II, and thereafter, with respect to any Distribution Date, the
excess of 100% over the applicable Senior Percentage for such date.

         SUBORDINATE PREPAYMENT PERCENTAGE: As of the Closing Date, determined
separately for each Loan Group, 0% for both Loan Group I and Loan Group II, and
thereafter, with respect to any Distribution Date, the excess of 100% over the
applicable Senior Prepayment Percentage.

         SUBORDINATE PRINCIPAL AMOUNT: For each Loan Group on any Distribution
Date, will be equal to the sum of:

         (1)    the applicable Subordinate Percentage of the related Principal
                Payment Amount (exclusive of the portion thereof attributable
                to the sum of the Group I Discount Fractional Principal

         (2)    the applicable Subordinate Principal Prepayment Amount; and
         (3)    the applicable Subordinate Liquidation Amount;

         PROVIDED, HOWEVER, that the Subordinate Principal Amount applicable to
         Group I Loans shall be reduced by the amounts required to be
         distributed to the Class IA-P Certificates with respect to Group I
         Discount Fractional Principal Shortfall on such Distribution Date and
         the Subordinate Principal Amount applicable to Group II Loans shall be
         reduced by the amounts required to be distributed to the Class IIA-P
         Certificates with respect to the Group II Discount Fractional Principal
         Shortfall on such Distribution Date; PROVIDED, FURTHER, that the

         Subordinate Principal Amount for any Distribution Date for either Loan

         distributed to the Senior Certificates relating to the other Loan Group
         pursuant to the provisions described in the definition of "Certificate
         Distribution Amount" herein.

Any reduction in the applicable Subordinate Principal Amount pursuant to the
proviso above shall offset the amount calculated pursuant to clause (1), clause
(3) and clause (2), in such order of priority. On any Distribution Date, the
applicable Subordinate Principal Amount shall be allocated pro rata, by Class
Principal Balance, among the Classes of Subordinate Certificates and paid in the
order of distribution to such Classes pursuant to clauses (I)(B)(i)(b) and
(I)(D)(i)(b) of the definition of "Certificate Distribution Amount" herein,
except as otherwise stated in such definition. Notwithstanding the foregoing, on
any Distribution Date prior to distributions on such date, if the applicable
Subordination Level for any Class of Subordinate Certificates is less than such
percentage as of the Closing Date, the pro rata portion of the applicable
Subordinate Principal Prepayment Amount otherwise allocable to the Class or
Classes junior to such Class will be distributed to the most senior Class of the
Subordinate Certificates for which the Subordination Level is less than such
percentage as of the Closing Date, and to the Classes of Subordinate
Certificates senior thereto, pro rata according to the Class Principal Balances
of such Classes.

         SUBORDINATE PRINCIPAL PREPAYMENT AMOUNT: For each Loan Group on any
Distribution Date, the applicable Subordinate Prepayment Percentage of the

Loans, of the portion thereof attributable to the sum of the Group I Discount
Fractional Principal Amounts and with respect to the Group II Loans, of the
portion thereof attributable to the sum of the Group II Discount Fractional
Principal Amounts as applicable for such Distribution Date).

         SUBORDINATION LEVEL: On any specified date, with respect to any Class
of Subordinate Certificates, the percentage obtained by dividing: (1) the sum of
the Class Principal Balances of all Classes of Certificates which are
subordinate in right of payment to such Class as of such date before giving
effect to distributions or allocations of Realized Losses on the Loans on such
date; by (2) the sum of the Class Principal Balances of all Classes of
Certificates as of such date before giving effect to distributions or
allocations of Realized Losses on the Loans on such date.

         SUBSTITUTE LOAN: As defined in Section 2.2.

         deliver or cause to be delivered to the Trustee a true and correct copy
         of such Mortgage, together with (1) in the case of a delay

         Officer's Certificate signed by a Responsible Officer of the Seller

The documents and instruments set forth in clauses (i) - (v) 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 to the effect that such recordation is
not necessary to protect the Trustee's and the Certificateholders' interest in
the related Mortgage Loans, 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

                                      -54-

<PAGE>

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 9-313 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 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 LaSalle Bank National Association,
Standard Federal Bank, N.A. or any bank or trust company approved by the
Depositor as Custodian of the documents or instruments referred to under (i)
through (v) 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.

         (a) 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

                                      -55-

<PAGE>

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.

         (b) No later than 90 days after the Closing Date, the Trustee agrees,
for the benefit of the Certificateholders, to review each Mortgage File
delivered to it and to execute and deliver, or cause to be executed and
delivered, to the Depositor and the Trustee an Interim Certification
substantially in the form attached hereto as Exhibit C-1. In conducting such
review, the Trustee agrees to ascertain that all required documents set forth in
items (i), (ii) and (v) and, to the extent delivered to the Trustee, items (iii)
and (iv) 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) and (iv). Neither the Trustee
nor the Custodian 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. 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 90-day period the Trustee finds
any document constituting part of the Mortgage File not to have been executed or
received, or to be unrelated to the Loans identified in 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 such 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 Mortgage Interest 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 the Loan
being substituted for 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

                                      -56-

<PAGE>

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, that if the defect
would cause the Loan to be other than a "qualified mortgage" as defined in
Section 860(G)(a)(3) of the Code such cure, repurchase or substitution must
occur within 90 days from the date such material defect was discovered, unless
the Trustee shall have received from the Depositor an Opinion of Counsel to the
effect that such cure, repurchase or substitution will not adversely affect the
REMIC status of REMIC I, REMIC II or REMIC III 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.

         (c) In addition, the Trustee agrees, for the benefit of
Certificateholders, to review each Mortgage File delivered to it within 180 days
after the Closing Date, or with respect to assignments which must be recorded,
within 180 days, after execution of this Agreement and to execute and deliver,
or cause to be executed and delivered, to the Depositor and the Trustee a Final
Certification substantially in the form attached hereto as Exhibit C-2. In
conducting such review, the Trustee agrees that if at the conclusion of such
180-day period the Trustee finds a material defect, the Trustee shall promptly
notify the Depositor, which shall have a period of 90 days after the REMIC has
received such notice to correct or cure any such material 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 such notice, either repurchase the related Loan or substitute
for any Loan to which such material defect relates in accordance with this
Agreement.

         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
related 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.

                  (ii) that as of the date of the transfer of the Loans to the

         and clear of all liens, pledges, charges or security interests of any
         nature and has full right and authority, subject to no interest or
         participation of, or agreement with, any other party, to sell and
         assign the same;

                  (iii) that as of the date of initial issuance of the
         Certificates, no payment of principal of or interest on or in respect
         of any Loan is 30 days or more past due from the Due Date of such Loan;

                  (iv) that to the best of the Depositor's knowledge, as of the
         date of the transfer of the Loans to the Trustee, there is no valid
         offset, defense or counterclaim to any Mortgage Note or Mortgage;

                  (v) that as of the date of the initial issuance of the
         Certificates, there is no proceeding pending, or to the best of the
         Depositor's knowledge, threatened for the total or partial condemnation
         of any of the Mortgaged Property and, to the best of the Depositor's
         knowledge the Mortgaged Property is free of material damage and is in
         good repair and neither the Mortgaged Property nor any improvement
         located on or being part of the Mortgaged Property is in violation of
         any applicable zoning law or regulation;

                  (vi) that each Loan complies in all material respects with
         applicable state or federal laws, regulations and other requirements,
         pertaining to usury, equal credit opportunity and disclosure laws, and
         each Loan was not usurious at the time of origination;

                  (vii) that to the best of the Depositor's knowledge, as of the
         date of the initial issuance of the Certificates, all insurance
         premiums previously due and owing with respect to the Mortgaged
         Property have been paid and all taxes and governmental assessments
         previously due and owing, and which may become a lien against the
         Mortgaged Property, with respect to the Mortgaged Property have been
         paid;

                  (viii) that each Mortgage Note and the related Mortgage are
         genuine and each is the legal, valid and binding obligation of the
         maker thereof, enforceable in accordance with its terms except as such
         enforcement may be limited by bankruptcy, insolvency, reorganization or
         other similar laws affecting the enforcement of creditors' rights
         generally and by general equity principles (regardless of whether such
         enforcement is considered in a proceeding in

                                      -58-

<PAGE>

         equity or at law); all parties to the Mortgage Note and the Mortgage
         had legal capacity to execute the Mortgage Note and the Mortgage; and
         each Mortgage Note and Mortgage have been duly and properly executed by
         the Mortgagor;

                  (ix) that each Mortgage is a valid and enforceable first lien
         on the property securing the related Mortgage Note, and that each Loan
         is covered by an ALTA mortgagee title insurance policy or other form of
         policy or insurance generally acceptable to FNMA or FHLMC, issued by,
         and is a valid and binding obligation of, a title insurer acceptable to
         FNMA or FHLMC insuring the originator, its successor and assigns, as to
         the lien of the Mortgage in the original principal amount of the Loan
         subject only to (a) the lien of current real property taxes and
         assessments not yet due and payable, (b) covenants, conditions and
         restrictions, rights of way, easements and other matters of public
         record as of the date of recording of such Mortgage acceptable to
         mortgage lending institutions in the area in which the Mortgaged
         Property is located or specifically referred to in the appraisal
         performed in connection with the origination of the related Loan and
         (c) such other matters to which like properties are commonly subject
         which do not individually, or in the aggregate, materially interfere
         with the benefits of the security intended to be provided by the
         Mortgage;

                  (x) that as of the initial issuance of the Certificates,
         neither the Depositor nor any prior holder of any Mortgage has, except
         as the Mortgage File may reflect, modified the Mortgage in any material
         respect; satisfied, canceled or subordinated such Mortgage in whole or
         part; released such Mortgaged Property in whole or in part from the
         lien of the Mortgage; or executed any instrument of release,
         cancellation, modification or satisfaction;

                  (xi)     that each Mortgaged Property consists of a fee simple
         estate or a condominium form of ownership in real property;

                  (xii) no foreclosure action is threatened or has been
         commenced (except for the filing of any notice of default) with respect
         to the Loan; and except for payment delinquencies not in excess of 30
         days, to 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 the Depositor has not waived any default, breach, violation or
         event of acceleration;

                  (xiii) that each Loan was originated on FNMA or FHLMC uniform
         instruments for the state in which the Mortgaged Property is located;

                  (xiv) that based upon a representation by each Mortgagor at
         the time of origination or assumption of the applicable Loan, 95.63% of
         the Group I Loans and 95.52% of the Group II Loans, measured by
         Principal Balance, were to be secured by primary residences and no

                                      -59-

<PAGE>

         more than 4.37% of the Group I Loans and 4.48% of the Group II Loans,
         measured by Principal Balance, were to be secured by second homes;

                  (xv) that an appraisal of each Mortgaged Property was
         conducted at the time of origination of the related Loan, and that each
         such appraisal was conducted in accordance with FNMA or FHLMC criteria,
         on FNMA or FHLMC forms and comparables on at least three properties
         were obtained;

                  (xvi)  that no Loan had a Loan-to-Value Ratio at origination
         in 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,

         similar institution which is supervised and examined by a federal or
         state authority or (ii) a mortgagee approved by the Secretary of
         Housing and Urban Development pursuant to Sections 203 and 211 of the
         National Housing Act or (B) originated or underwritten by an entity
         employing underwriting standards consistent with the underwriting
         standards of an institution as described in subclause (A)(i) or (A)(ii)
         above;

                  (xix) each Loan is a "qualified mortgage" within the meaning
         of 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;

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

                  (xxii) No Loan is a "high-cost home loan" as defined in the
         Georgia Fair Lending Act, as amended, or in the New York Predatory
         Lending Law, codified as N.Y. Banking Law ss. 6-l, N.Y. Gen. Bus.
         Lawss.771-a, and N.Y. Real Prop. Acts Lawss.1302.

         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, any 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.

                                      -60-

<PAGE>

         Within 90 days of its discovery or its receipt or any Seller's receipt
of notice of breach, the Depositor shall or shall cause such Seller to cure such
breach 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 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 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, REMIC II or REMIC III 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 Servicers are 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 or the related Seller 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, the related Seller
or their 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, REMIC II and REMIC III 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 III 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 III shall consist of Component R-3 of the Class R
Certificate, which component shall have $100 principal balance. The following
table irrevocably sets forth the designation, the Uncertificated REMIC I
Pass-Through Rate and the initial Uncertificated Principal Balances for each
REMIC I Regular Interest, each of which is hereby designated as a "regular
interest" (within the meaning of

                                      -61-

<PAGE>

Section 860G(a)(1) of the Code) in REMIC I. 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 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, as of the Closing Date, the
longest remaining amortization schedule, irrespective of its scheduled maturity.
None of the REMIC I Regular Interests will be certificated.

(1)      REMIC I Regular Interest LTI-I-IO will not have an Uncertificated
         Principal Balance and is not entitled to receive distributions of
         principal. Instead, interest will accrue on an Uncertificated Notional
         Balance equal to the aggregate Stated Principal Balance of the Premium
         Mortgage Loans in Loan Group I.
(2)      REMIC I Regular Interests LTI-I-IO will accrue interest at a per annum
         rate equal to the excess of the Pass-Through Rate on each Group
         I Premium Loan less 5.50%.
(3)      REMIC I Regular Interests LTI-I-PO is a principal only interest and
         will not be entitled to distributions of interest.

         (c) Distributions on REMIC I Regular Interests LTI-I-IO shall be made
from the Group I Premium Loans so that such REMIC I Regular Interest receives
interest in excess of 5.50% of such Loans. REMIC I Regular Interest LTI-I-PO
shall receive a portion of the principal received on the Group I Discount Loans
equal to the Group I Discount Fraction multiplied by the principal balance of
each such Loan. With respect to each remaining REMIC I Regular Interest, on each
Distribution Date the Trustee shall be deemed to distribute in respect of each
such REMIC I Regular Interest: (i) Uncertificated Accrued Interest for such
REMIC I Regular Interest for such Distribution Date, plus any Uncertificated
Accrued Interest thereon remaining unpaid from any previous Distribution Date,
and (ii) principal in an amount equal to that distributed in respect of the
Corresponding Class. Realized Losses allocated to the Group I Certificates shall
be allocated to each REMIC I Regular Interest in amounts equal to the amounts
allocated to the Corresponding Class.

         (d) The following table irrevocably sets forth the designation, the
Uncertificated REMIC II Pass-Through Rate and the initial Uncertificated
Principal Balance for each REMIC II Regular Interest, each of which is hereby
designated as a "regular interest" (within the meaning of Section 860G(a)(1) of
the Code) in REMIC II. Solely for purposes of satisfying Treasury regulation
Section 1.860G-1(a)(4)(iii) the "latest possible maturity date" for each of the
REMIC II Regular Interests 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, as of the Closing Date, the longest remaining
amortization schedule, irrespective of its scheduled maturity. None of the REMIC
II Regular Interests will be certificated.

Fund to any tax on contributions to the REMIC under Section 860G(d) of the Code.

         Section 2.7 REPRESENTATIONS AND WARRANTIES OF THE SERVICERS. Each
Servicer hereby represents, warrants and covenants to the Trustee for the
benefit of Certificateholders that, as of the date of execution of this
Agreement, solely as to itself:

                                      -64-

<PAGE>

         (a) such 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 such Servicer and
its performance of and compliance with the terms of this Agreement will not
violate such 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 such Servicer is a party or which may be applicable to
such 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 such 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) such 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 agency, which default might have consequences that would
materially and adversely affect the condition (financial or other) or operations
of such 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 such Servicer's
knowledge, threatened against such Servicer which would prohibit its entering
into this Agreement or performing its obligations under this Agreement.

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.

                      ADMINISTRATION AND SERVICING OF LOANS

         Section 3.1 SERVICERS TO ACT AS SERVICERS; ADMINISTRATION OF THE LOANS.

         (a) Each Servicer shall service and administer the related Loans on
behalf of the Trust Fund solely in the best interests of and for the benefit of
the Certificateholders (as determined by each 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 a related Servicer, any
         sub-servicer, any special servicer or any Affiliate of such Servicer,
         any sub-servicer or any special servicer may have with the related
         Mortgagor;

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

                  (iii) a 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
         a related Servicer, any sub-servicer or any special servicer, of any
         other mortgage loans or property.

         In addition, each 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.
Each Servicer may perform its servicing responsibilities through agents or
independent contractors, but shall not thereby be released from any of its
responsibilities hereunder and each such Servicer shall diligently pursue all of
its rights against such agents or independent contractors.

         To the extent consistent with the foregoing and subject to any express
limitations set forth in this Agreement, each 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 related 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, each Servicer, as an independent
contractor, shall service and administer the

                                      -66-

<PAGE>

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, each 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 Mortgage Notes in connection with
refinancings (in jurisdictions where such assignments are 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, a 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. Each 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 a Servicer to carry out its servicing and
administrative duties hereunder, upon a Servicer's written request accompanied
by the forms of any documents requested, the Trustee shall execute and deliver
to the related 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 related Servicer
shall indemnify the Trustee for, any action taken by such Servicer pursuant to
the application of any such power of attorney. The relationship of each 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, each
Servicer and any affiliate of a Servicer (i) may with respect to defaulted
mortgage loans 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) Each Servicer, Trustee and Depositor intend that REMIC I, REMIC II
and REMIC III formed hereunder shall constitute, and that each 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
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

                                      -67-

<PAGE>

to be made) an election, on behalf of each of REMIC I, REMIC II and REMIC III,
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, REMIC II Regular Interests, or REMIC III Certificates
are outstanding so as to maintain the status of each of REMIC I, REMIC II and
REMIC III 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 any of REMIC I, REMIC II or REMIC III.

         (c) Each Servicer may enter into sub-servicing agreements with third
parties with respect to any of its respective rights and 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 rights and 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). As long as the related
Servicer has any obligations to service the Loans hereunder (and it has not
assigned such obligations pursuant to Section 3.1(c)), the Loans shall be
serviced by a FNMA approved lender or a FHLMC seller/servicer in good standing.

         Any sub-servicing agreement entered into by AAMG with a Person other
than the Depositor shall provide that it may be assumed or terminated by the
Trustee if the Trustee has assumed the duties of AAMG as Servicer, without cost
or obligation to the assuming or terminating party or the Trust Fund, upon the
assumption by such party of the obligations of such Servicer pursuant to Section
7.5. The Trustee shall not be obligated to assume any sub-servicing agreement
entered into by WMMSC and a third party.

         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 applicable 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 a
Servicer (including by reason of an Event of Default which is not cured by the
related Servicer within the time permitted hereunder), upon request of the
Trustee, such 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.

                                      -68-

<PAGE>

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

         Each Servicer, as an 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, such 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.

         (e) Notwithstanding any sub-servicing agreement, any of the provisions
of this Agreement relating to agreements or arrangements between a 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, such 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
such Servicer alone were servicing and administering the Loans. Each Servicer
shall be entitled to enter into an agreement with any sub-servicer providing for
indemnification of such 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.

         (f) Notwithstanding anything in this Agreement to the contrary, the
purchase of any of WMMSC-serviced Mortgage Loan by any Person shall be subject
to the rights of WMMSC to continue servicing such Mortgage Loan for the same
servicing fee substantially in accordance with the terms of this Agreement.

         Section 3.2 COLLECTION OF CERTAIN LOAN PAYMENTS; CUSTODIAL ACCOUNT FOR
                     P&I.

         (a) Each 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 Servicers
agree 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, each 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 such Servicer shall continue

                                      -69-

<PAGE>

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 a Servicer shall exercise any such
right, except that the Trustee shall exercise such right at the written
direction of a 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 Servicers 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, REMIC II or REMIC III 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) Each Servicer shall establish and maintain one or more separate
accounts as set forth in Article I (collectively, 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 related 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):

                  (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 related
         Servicer is entitled to retain as Servicing Fees (adjusted for any
         amounts related to Compensating Interest) or other servicing
         compensation (including any prepayment penalties) pursuant to Section
         3.9, as adjusted pursuant to Section 4.6;

                  (iii) All net Liquidation Proceeds;

                  (iv) All Insurance Proceeds received by a 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 related Servicer's normal servicing procedures, and
         all amounts deposited by a 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;

                                      -70-

<PAGE>

                  (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) Each 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. 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 such 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 related Servicer, and shall be payable to such Servicer. The amount of any
losses incurred in respect of any such investments shall be deposited in the
Custodial Account for P&I by such 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 a Servicer in the
Custodial Account for P&I. All funds deposited by a Servicer in the Custodial
Account for 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 Servicers 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
related 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. Each 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.
Each Servicer may, from time to time, make withdrawals from the Custodial
Account for P&I 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, each 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

                                      -71-

<PAGE>

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 a 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 a 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 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 a Servicer 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 or its designee in order that the
Trustee or its designee 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) each Servicer's entitlement thereto is limited to collections or
other recoveries on the related Loan, the

                                      -72-

<PAGE>

Servicers 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.

         Each 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.

         Each Servicer may establish, or cause to be established, two or more
Custodial Accounts for P&I into which funds collected by such Servicer or its
subservicers in connection with the related Loans may be deposited. Funds
collected in connection with mortgage loans other than the related Loans may
also be deposited in the Custodial Accounts for P&I and co-mingled with
collections on the related Loans. Each 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) Each Servicer shall establish and maintain one or more accounts
(each, an "Escrow Account") into which all Escrow Payments shall be promptly
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. Each Servicer shall notify the Trustee in writing of the
location and account number of each Escrow Account it establishes and shall
notify the Trustee prior to any subsequent change thereof. 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 related
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 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 related Servicer as additional servicing compensation.

         (b) With respect to each Loan, the related 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. Each 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 related Servicer shall advance,
or cause to be advanced, the amount of any shortfall unless such 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

                                      -73-

<PAGE>

limitation Insurance Proceeds and Liquidation Proceeds), or otherwise. Each
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 a
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.

         Each Servicer may establish, or cause to be established, two or more
Escrow Accounts into which funds collected by such 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. Each 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. Each 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. Each
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. Each 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. Each 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 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 each 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.
Each 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

                                      -74-

<PAGE>

federally designated special flood hazard area, the related 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 related 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 related 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 related
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 a 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 related
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 a Servicer in maintaining any such insurance shall be recoverable by
such Servicer pursuant to Section 3.3. In the event that a Servicer shall obtain
and maintain a blanket policy issued by an insurer that qualifies under the
guidelines set forth for such 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 such 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.

         Each 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 coverage with responsible companies covering such
Servicer's officers and employees and other persons acting on behalf of such
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
related Servicer to continue to be a FNMA or a FHLMC-qualified Servicer and
shall protect and insure such 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 a 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 related 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,
each 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. Each 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 related
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 related 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 related Servicer for entering into an assumption or
substitution of liability agreement will be retained by such Servicer as
servicing compensation.

         Notwithstanding the foregoing paragraph or any other provision of this
Agreement, a 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 a 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 related
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, such
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 a 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

                                      -76-

<PAGE>

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 Certificateholder, but only
to the extent that such gain is not necessary to make distributions to the
Certificateholders of the other Classes of Certificates. Each 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. Within 30 days after
receipt of Liquidation Proceeds in respect of a Liquidated Loan, the related
Servicer shall provide to the Trustee a statement of accounting for the related
Liquidated Loan, including without limitation (i) the Loan number, (ii) the date
the Loan was acquired in foreclosure or deed in lieu, and the date the Loan
became a Liquidated Loan, (iii) the gross sales price and the related selling
and other expenses, (iv) accrued interest calculated from the foreclosure date
to the liquidation date, and (v) such other information as the Trustee may
reasonably specify.

         (b) Prior to any such foreclosure, with respect to (a) any Group I
Loan, WMMSC may, at its option, repurchase any Group I Loan which is 90 days or
more delinquent and which WMMSC determines in good faith would otherwise become
subject to foreclosure proceedings or any Group I 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; and (b) any Group II Loan, AAMG may, at
its option, repurchase any Group II Loan which is 30 days or more delinquent;
provided that any such repurchase shall only be made if (i) the related Servicer
has a contractual right to require the third party seller of such delinquent
Loan to repurchase such Loan, (ii) such repurchase is made to facilitate a
repurchase by such third party seller and (iii) such repurchase is made at a
price equal to the Purchase Price. 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 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 not be necessary and appropriate to effect
such compliance and/or respond to such circumstances, the related Servicer will
not conduct such foreclosure proceedings. If a Servicer otherwise becomes aware,
under its customary servicing procedures, of an environmental hazard with
respect to a Loan for which foreclosure proceedings are contemplated, such
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

                                      -77-

<PAGE>

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 related 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 any of REMIC I, REMIC II or
REMIC III 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 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, REMIC II and REMIC III to remain qualified as REMICs under the REMIC
Provisions. The related 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
related Servicer shall either itself or through an agent selected by such
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 such Servicer deems
to be in the best interest of such 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 related Servicer in
connection therewith, be deposited into the Custodial Account for P&I pursuant
to Section 3.3(b)(viii).

         (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 Servicers 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 a
         Servicer for the benefit of the Trust Fund; or

                                      -78-

<PAGE>

                  (ii) the related 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 any of REMIC I, REMIC II or REMIC
         III 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 related
Servicer of a notification that the payment in full will be escrowed in a manner
customary for such purposes, such Servicer will immediately notify the Trustee
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 File. Upon receipt
of such Officer's Certificate and request, the Trustee, the Custodian or any
such sub-custodian, as applicable, shall not later than the 5th Business Day
release or cause to be released the related Mortgage File to the related
Servicer. Upon the Trustee's receipt of any release or reconveyance documents or
instruments relating to the Loan paid in full, the Trustee shall, not later than
the 5th succeeding Business Day, execute and return such documents and
instruments to such Servicer. From time to time and as appropriate for the
servicing or foreclosure of any Loan, the Trustee shall, upon written request of
the related 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 related 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
related Servicer to return each and every document previously requested from the
Mortgage File to the Trustee when the need therefor by such 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 related 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.

         Each 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. Each
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
related Servicer and need not be deposited in the Custodial Account for P&I.
Each Servicer shall also be entitled to additional servicing compensation out of
Liquidation Proceeds to the extent provided in Section 3.3(b). Each Servicer
shall be required to pay all expenses incurred by it in connection with its

respects, subject to such exceptions and other qualifications that may be
appropriate. In connection with such letter of representation, such Servicer
shall disclose to such firm of independent public accountants all significant
deficiencies relating to such Servicer's compliance with the minimum servicing
standards set forth in this Agreement. In rendering its report such firm may

public accountants who are members of the American Institute of Certified Public
Accountants to furnish a statement to the Trustee, the Certificate Administrator
and each Rating Agency to the effect that such firm has examined certain
documents and records relating to the servicing of the Group II Loans and that,
either (a) on the basis of such examination conducted substantially in
compliance with the audit program for mortgages serviced for FHLMC, such firm is
of the opinion that such servicing has been conducted in compliance with the
manner of servicing set forth in agreements substantially similar to this
Agreement except for (i) such exceptions as such firm shall believe to be
immaterial and (ii) such other exceptions as shall be set forth in such
statement or, (b) that their examination conducted substantially in compliance
with the uniform single audit program for mortgage bankers disclosed no
exceptions or errors in records relating to mortgage loans serviced for others
that in their opinion are material and that Paragraph 4 of that program requires
them to report. Copies of the statements required above shall be provided to
Certificateholders upon request by the related Servicer, or by the Trustee at
the related Servicer's expense.

         Section 3.13 ACCESS TO CERTAIN DOCUMENTATION AND INFORMATION REGARDING
THE LOANS. Each 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 related Servicer designated by it. The Trustee or its designee may

Servicer hereunder.

         Section 3.14 [RESERVED].

         Section 3.15 SALE OF DEFAULTED LOANS AND REO PROPERTIES.

         (a) With respect to any Defaulted Loan or REO Property which a Servicer
has determined to sell in accordance with the standards set forth in Section
3.7, such Servicer shall deliver to the Trustee an Officer's Certificate to the
effect that no satisfactory arrangements can be made for collection of
delinquent payments thereon pursuant to Section 3.2, and, consistent with the
servicing standard set forth in Section 3.1 and with a view to the best economic
interest of the Trust Fund, such Servicer has determined to sell such Defaulted
Loan or REO Property in accordance with this Section 3.15. The related 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 Purchase Price therefor), but shall in any event,
so offer to sell any REO Property no later than the time determined by such
Servicer to be sufficient to result in the sale of such REO Property within the
period specified in Section 3.7(c). The related Servicer shall 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.

                                      -82-

<PAGE>

         In the absence of any such bid or purchase by the related Servicer,
such Servicer shall accept the highest bid received from any Person that is
determined by such 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 related Servicer shall not be obligated by either of the foregoing
paragraphs or otherwise to accept the highest bid if such 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 related 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 related 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 related 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 related Servicer 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 related
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) Each 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 related 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 related Servicer, the 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 related Servicer or the Trustee.

                                      -83-

         (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 related 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 related
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
related 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. Each 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 related 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 related Servicer acted in accordance with its
normal procedures.

         Section  3.20     ALLOCATION OF REALIZED LOSSES.

         Prior to each Distribution Date, the related Servicer shall determine
the amount of Realized Losses, if any, with respect to each Loan.

         The amount of Realized Losses shall be evidenced by an Officer's
Certificate signed by a Responsible Officer of the related Servicer. 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, for losses on Group I Loans, to the Class
IA Certificates (other than the Class IA-2 Certificates and Class IA-X
Certificates), by Pro Rata Allocation, and for losses on Group II Loans,

                                      -84-

<PAGE>

to the Class IIA Certificates (other than the Class IIA-6 Certificates and Class
IIA-X Certificates) and the Class R Certificate, by Pro Rata Allocation, until
the Certificate Principal Balances thereof have been reduced to zero; PROVIDED,
HOWEVER, that prior to the Credit Support Depletion Date if the loss is
recognized (a) with respect to a Group I Discount Loan, the Group I Discount
Fraction of such loss shall be allocated to the Class IA-P Certificates and the
remainder of such loss will be allocated as described in clause (i) above, and
(b) with respect to a Group II Discount Loan, the Group II Discount Fraction of
such loss shall be allocated to the Class IIA-P Certificates and the remainder
of such loss will be allocated as described in clause (i) above 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, for losses on Group I Loans, to the Class IA Certificates (other
than the Class IA-P Certificates), by Pro Rata Allocation, and for losses on
Group II Loans to the Class IIA Certificates and the Class R Certificate (other
than the Class IIA-P Certificates), by Pro Rata Allocation, until the
Certificate Principal Balances thereof have been reduced to zero.

         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 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 in both Loan Groups, 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 related 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 such Accrual Certificate on
the Closing Date, if lower in reduction thereof.

information that is in the possession of the Depositor and the Servicers and is
not, to the best of the Depositor's or the related Servicer's knowledge, in the
possession of the Trustee or the Certificate Administrator and which is required
to be included in such reports. Neither the Trustee or the Certificate
Administrator, as applicable, nor the Servicers shall have any liability with
respect to the Trustee's or the Certificate Administrator's failure to properly
prepare or file such periodic reports resulting from or relating to the
Trustee's or the Certificate Administrator's inability or failure to obtain any
information not resulting from the Trustee's or the Certificate Administrator's
own negligence or willful misconduct. Prior to January 30 of the first year in
which the Certificate Administrator or the Trustee, as applicable, is able to do
so under applicable law, the Certificate Administrator or the Trustee shall file
a Form 15 Suspension Notification with respect to the Trust Fund. Any Form 10-K
that is filed with the Commission in connection with this clause (c) shall
include a certification, signed by the senior officer in charge of the servicing
functions of AAMG, in the form attached as Exhibit S hereto or such other form
as may be required or permitted by the Commission (the "Form 10-K
Certification"), in compliance with Rule 13a-14 and 15d-14 under the Exchange
Act and any additional directives of the Commission. In connection with the Form
10-K Certification, the Certificate Administrator or the Trustee, as applicable,
and WMMSC shall each provide AAMG with a back-up certification substantially in
the form attached hereto as Exhibit T in the case of the Certificate
Administrator or the Trustee and Exhibit U in the case of WMMSC (each, a
"Back-up Certification"). This Section 4.2(c) may be amended in accordance with
this Agreement without the consent of the Certificateholders.

         WMMSC agrees to indemnify and hold harmless each of AAMG, the
Depositor, the Certificate Administrator and the Trustee and each Person, if
any, who "controls" AAMG, the Depositor, the Certificate Administrator or the
Trustee within the meaning of the 1933 Act and their respective officers and
directors against any and all losses, penalties, fines, forfeitures, legal fees
and related costs, judgments and any other costs, fees and expenses that such
Person may sustain arising out of third party claims based on (i) the failure of
WMMSC to deliver or cause to be delivered when

                                      -89-

<PAGE>

required any related Back-up Certification required pursuant to this Section
4.2(c) or (ii) any material misstatement or omission contained in any related
Back-up Certification provided pursuant to this Section 4.2(c). If an event
occurs that would otherwise result in an indemnification obligation under
clauses (i) or (ii) above, but the indemnification provided for in this Section
4.2(c) by WMMSC is unavailable or insufficient to hold harmless such Persons,
then WMMSC shall contribute to the amount paid or payable by such Persons as a
result of the losses, claims, damages or liabilities of such Persons in such
proportion as is appropriate to reflect the relative fault of AAMG, the
Depositor, Certificate Administrator or Trustee on the one hand and WMMSC on the
other. WMMSC acknowledges that AAMG, the Depositor, the Certificate
Administrator and the Trustee are relying on WMMSC's performance of its
obligations under this Agreement in order to perform their respective
obligations under this Section 4.2(c).

         The Certificate Administrator agrees to indemnify and hold harmless
each of the Depositor, the Trustee and the Servicers and each Person, if any,
who "controls" the Depositor, the Trustee and the Servicers within the meaning
of the 1933 Act and their respective officers and directors against any and all
losses, penalties, fines, forfeitures, legal fees and related costs, judgments
and any other costs, fees and expenses that such Person may sustain arising out
of third party claims based on (i) the failure of the Certificate Administrator
to deliver or cause to be delivered when required any related Back-up
Certification required pursuant to this Section 4.2(c) or (ii) any material
misstatement or omission contained in any related Back-up Certification provided
pursuant to this Section 4.2(c). If an event occurs that would otherwise result
in an indemnification obligation under clauses (i) or (ii) above, but the
indemnification provided for in this Section 4.2(c) by the Certificate
Administrator is unavailable or insufficient to hold harmless such Persons, then
the Certificate Administrator shall contribute to the amount paid or payable by
such Persons as a result of the losses, claims, damages or liabilities of such
Persons in such proportion as is appropriate to reflect the relative fault of
the Depositor, Servicers or Trustee on the one hand and the Certificate
Administrator on the other. The Certificate Administrator acknowledges that the
Depositor, the Servicers and the Trustee are relying on the Certificate
Administrator's performance of its obligations under this Agreement in order to
perform their respective obligations under this Section 4.2(c).

         Section 4.3 ADVANCES BY THE SERVICER; DISTRIBUTION REPORTS TO THE
TRUSTEE. To the extent described below, each 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. Each 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 related 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.

         With respect to WMMSC, prior to the close of business on the second
Business Day following the 18th day of the month in which each Distribution Date
occurs, and with respect to AAMG, prior to the close of business on or before
each Determination Date, such Servicer shall determine whether or not it will
make an Advance on the next Withdrawal Date and shall furnish

                                      -90-

<PAGE>

a statement to the Certificate Administrator, if any, 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 related
Servicer prior to the Withdrawal Date preceding such Distribution Date and the
related Servicer shall have determined that an Advance shall be made in
accordance with this Section 4.3, the related Servicer shall so specify and
shall specify the aggregate amount of such Advance.

         In the event that a Servicer shall be required to make an Advance, it
shall on the Withdrawal Date either (i) deposit in the Certificate Account an
amount equal to such Advance, (ii) direct the Trustee or the Certificate
Administrator (if so appointed by the Trustee) to make an appropriate entry in
the records of the Certificate Account or such 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 related Servicer by
deposit in the Certificate Account on any future Withdrawal Date to the extent
that funds in the Certificate Account on the related 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.

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

         In the event that the Trustee has appointed a Certificate
Administrator, prior to 5:00 P.M. New York City time on the Withdrawal Date, the
Certificate Administrator 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).

         Section 4.4 NONRECOVERABLE ADVANCES. Any Advance previously made by or
on behalf of a Servicer with respect to a Loan that such 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 a 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 such Servicer
delivered to the Trustee on the Determination 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 related Servicer is a party, (a) the related
Servicer shall not be obligated to, and shall not, make any advance that, after
reasonable inquiry and in its sole discretion, it

                                      -91-

<PAGE>

determines would be a Nonrecoverable Advance, and (b) the related 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 2004 each
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, each Servicer, on or before February 28th of each year,
commencing with 2004, shall provide to the Internal Revenue Service, the Trustee
and the Certificate Administrator, if any, reports relating to each instance
occurring during the previous calendar year in which each 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 each 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 related 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 related 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.

         (a) 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 the primary cause of
such tax was a breach of such Servicer's duties under (x) Section 3.2 of this
Agreement to not make any modification, waiver or amendment of any Mortgage Loan
which would cause any REMIC created hereunder to fail to qualify as a REMIC or
result in the imposition of any tax under Section 860F(a) or Section 860G(d) of
the Code or (y) Section 3.7(c) of this Agreement to not cause any REO Property
to fail to qualify as "foreclosure property" within the meaning of Section
860G(a)(8) of the Code or to subject any REMIC created hereunder to the
imposition of any federal, state or local income taxes on the income earned from
such Mortgaged Property under Section 860G(c) of the Code or otherwise, then
such Servicer shall (A) pay such taxes when and as the same shall be due and
payable (but such obligation shall not prevent the related Servicer, the
Trustee, the Certificate Administrator, if any, or any other appropriate Person
from contesting any such tax in appropriate proceedings and shall not prevent
the related Servicer from withholding payment of such tax, if

                                      -92-

<PAGE>

permitted by law, pending the outcome of such proceedings), and (B) indemnify
and hold harmless the Trust Fund from and against, such taxes imposed on the
Trust Fund to the extent not paid under clause (A).

         (b) In the event that any tax is imposed on the Trust Fund and neither
Servicer is obligated to pay or indemnify the Trust Fund for such tax under
Section 4.7 (a), then the Trustee or Certificate Administrator shall pay such
tax, and the amount of such tax shall be first charged against amounts otherwise
distributable to the Holders of Component R-1 of the Class R Certificate (or, if
the tax relates to REMIC II, Component R-2 of the Class R Certificate or, if the
tax relates to REMIC III, Component R-3 of the Class R Certificate) 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 Regular Interests) on a pro rata basis. The Trustee or the
Certificate Administrator is hereby authorized to retain from amounts otherwise
distributable to the Certificateholders sufficient funds for the payment of such
tax pursuant to this Section 4.7(b).

         Section 4.8 TAX ADMINISTRATION.

         (a) The Trustee is hereby appointed as attorney-in-fact and agent for
the initial Tax Matters Person; provided, that the Trustee may appoint, and
hereby does so appoint, the Certificate Administrator as attorney-in-fact and
agent for the Tax Matters Person. The Trustee may, by written notice delivered
to the Certificate Administrator, revoke the appointment of the Certificate
Administrator as attorney-in-fact and agent for the Tax Matters Person, in which
case the Trustee shall act in such capacity.

         (b) In order to enable the Trustee or the Certificate Administrator, as
applicable, to perform its duties as set forth in this Section 4.8 and Section
3.1(b), AAMG agrees to provide any tax forms, instruments or other documents
related thereto, as the Trustee or the Certificate Administrator, as applicable,
may reasonably request, including, without limitation, any tax forms,
instruments or other documents prepared by AAMG pursuant to this Section 4.8. In
order to enable the Trustee or the Certificate Administrator, as applicable, to
perform its duties as set forth in this Section 4.8 and Section 3.1(b), each
Servicer shall use its best efforts to cause to be delivered to the Trustee or
the Certificate Administrator, as applicable, within ten (10) days after the
Closing Date all loan level information or data that the Trustee or the
Certificate Administrator, as applicable, determines to be relevant for tax
purposes to the valuations and offering prices of the Certificates, including,
without limitation, the price, yield, prepayment assumption and projected cash
flows. Thereafter, each Servicer shall use its best efforts to provide to the
Trustee or the Certificate Administrator, as applicable, promptly upon request
therefor, any such additional loan level information or data that the Trustee or
the Certificate Administrator, as applicable, may, from time to time, request in
order to enable the Trustee or the Certificate Administrator, as applicable, to
perform its duties as set forth in this Section 4.8 and Section 3.1(b).

         Section 4.9 EQUAL STATUS OF SERVICING FEE. The right of the related
Servicer to receive its applicable Servicing Fee will be equal and not
subordinate to the right of the Certificateholders to

                                      -93-

<PAGE>

receive principal and interest payments based on their interests as provided
herein. Each 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 AND CERTIFICATE ADMINISTRATOR.
The Trustee may appoint an Eligible Institution to act as a paying agent (the
"Paying Agent") or a certificate administrator (the "Certificate
Administrator"), as the case may be, 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, LaSalle Bank National Association will be the Certificate
Administrator and Paying Agent. If LaSalle Bank National Association ceases to
serve as Certificate Administrator or Paying Agent, the Trustee shall send
written notice to all Certificateholders (i) indicating that LaSalle Bank
National Association is no longer in such capacity and (ii) setting forth its
replacement, if any, appointed pursuant to this Section 4.10.

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.

         in a Residual Certificate shall be deemed by the acceptance or
         acquisition of such Ownership Interest to have agreed to be bound by
         the following provisions and to have irrevocably authorized the
         Trustee, the Certificate Administrator or the Paying Agent under clause
         (iii)(A) below to deliver payments to a Person other than such Person
         and to negotiate the terms of any

                           Permitted Transferee and shall promptly notify the
                           Trustee or the Certificate Registrar if not the same
                           Person as the Trustee of any change or impending
                           change in its status as a Permitted Transferee.

                  (2)      In connection with any proposed Transfer of any

                           satisfactory to the Depositor, representing and
                           warranting, among other things, that it is not a
                           Non-U.S. Person, that such transferee is a Permitted
                           Transferee, that it is not acquiring its Ownership
                           Interest in the Residual Certificate that is the
                           subject of the proposed Transfer as a nominee,
                           trustee or agent for any Person who is not a
                           Permitted Transferee, that for so long as it retains
                           its Ownership Interest in a Residual Certificate, it
                           will endeavor to remain a Permitted Transferee, and
                           that it has reviewed the provisions of this Section
                           5.1(c) and agrees to be bound by them, and (2) a
                           certificate, attached hereto as Exhibit I, from the
                           Holder wishing to transfer the Residual Certificate,
                           in form and substance satisfactory to the Depositor,
                           representing and warranting, among other things, that
                           no purpose of the proposed Transfer is to allow such
                           Holder to impede the assessment or collection of tax.

                  (3)      Notwithstanding the delivery of a Transferee
                           Affidavit and Agreement by a proposed Transferee
                           under clause (B) above, if the Trustee or the
                           Certificate Registrar if not the same Person as the
                           Trustee has actual knowledge that the proposed
                           Transferee is not a Permitted Transferee, no Transfer
                           of an Ownership Interest in a Residual Certificate to
                           such proposed Transferee shall be effected.

                  (4)      Each Person holding or acquiring any Ownership
                           Interest in a Residual Certificate agrees by holding
                           or acquiring such Ownership Interest (i) to require a
                           Transferee Affidavit and 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

                           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 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, any Servicer, the Certificate
         Administrator, 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 the 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 the 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

                                      -97-

<PAGE>

                  Person having an Ownership Interest in the 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 Certificate
         Administrator all information necessary to compute any tax imposed (A)
         as a result of the Transfer of an Ownership Interest in the 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 Certificate
         Administrator the following:

                  (1)      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

                  (2)      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:

                  ANY RESALE, TRANSFER OR OTHER DISPOSITION OF THIS
                  CERTIFICATE MAY BE MADE ONLY IF THE PROPOSED
                  TRANSFEREE PROVIDES A TRANSFEREE AFFIDAVIT AND
                  AGREEMENT TO THE DEPOSITOR, THE TRUSTEE AND THE
                  CERTIFICATE REGISTRAR THAT (1) SUCH TRANSFEREE IS

                  THE CODE (ANY SUCH PERSON DESCRIBED IN THE FOREGOING
                  CLAUSES (A), (B), OR (C) BEING HEREINAFTER REFERRED
                  TO AS A "DISQUALIFIED ORGANIZATION"), OR (D) AN
                  AGENT OF A DISQUALIFIED ORGANIZATION AND (2) NO
                  PURPOSE OF SUCH TRANSFER IS TO ENABLE THE TRANSFEROR
                  TO IMPEDE THE ASSESSMENT OR COLLECTION OF TAX. SUCH
                  AFFIDAVIT SHALL INCLUDE CERTAIN REPRESENTATIONS AS
                  TO THE FINANCIAL CONDITION OF THE PROPOSED
                  TRANSFEREE. NOTWITHSTANDING THE REGISTRATION IN THE
                  CERTIFICATE REGISTER OF ANY TRANSFER, SALE OR OTHER
                  DISPOSITION OF THIS CLASS R CERTIFICATE TO A
                  DISQUALIFIED ORGANIZATION OR AN AGENT OF A
                  DISQUALIFIED ORGANIZATION, SUCH REGISTRATION SHALL
                  BE DEEMED TO BE OF NO LEGAL FORCE OR EFFECT
                  WHATSOEVER AND SUCH PERSON SHALL NOT BE DEEMED TO BE
                  A CERTIFICATEHOLDER FOR ANY PURPOSE HEREUNDER
                  INCLUDING, BUT NOT LIMITED TO, THE RECEIPT OF
                  DISTRIBUTIONS ON THIS CERTIFICATE. EACH HOLDER OF
                  THE CLASS R CERTIFICATE BY ACCEPTANCE OF THIS
                  CERTIFICATE SHALL BE DEEMED TO HAVE CONSENTED TO THE
                  PROVISIONS OF THIS PARAGRAPH.

                  (vii) The Holder of the Class R Certificate issued hereunder,
         while not a Disqualified Organization, is the Tax Matters Person.

         (d) (i) No purchase or transfer of a Senior Certificate or a Senior
Subordinate Certificate or any interest therein shall be made by or to any
"employee benefit plan" subject to ERISA or any "plan" described by Section
4975(e)(1) of the Code, or any entity deemed to hold plan assets of any of the
foregoing by reason of a plan's investment in such entity (each, a "Plan")
unless (A) in the case of any such Class of Certificates (other than the Class R
Certificate), such Plan qualifies as an accredited investor as defined in Rule
501(a)(1) of Regulation D under the Securities Act and either (1) at the time of
such transfer, the Certificates are rated in one of the top four rating
categories by at least one Rating Agency, or (2) the purchaser is an insurance
company general account that is eligible for, and satisfies all of the
requirements of, Sections I and III of Prohibited Transaction Class

Exemption 95-60 ("PTCE 95-60") and (B) in the case of a Class R Certificate, the
Trustee receives an Opinion of Counsel acceptable to and in form and substance
satisfactory to and on which the Trustee, the Depositor, the Certificate
Registrar, the Certificate Administrator, if any, and the Servicers may rely, to
the effect that the purchase or holding of such Class R Certificate is
permissible under applicable law, will not constitute or result in any
non-exempt prohibited transaction under Section 406 of ERISA, or Section 4975 of
the Code (or comparable provisions of any subsequent enactments), and will not
subject the Trustee, the Certificate Registrar, the Certificate Administrator,
if any, the Depositor or the Servicers to any obligation or liability (including
obligations or liabilities under ERISA or Section 4975 of the Code) in addition
to those undertaken in this Agreement, which Opinion of Counsel shall not be an
expense of the Trustee, the Certificate Registrar, the Certificate
Administrator, if any, the Depositor or the Servicers. Each Person who acquires
a Senior Certificate or a Senior Subordinate Certificate shall be deemed to
certify that it meets the foregoing conditions, and that it will not transfer
such Certificate in violation of the foregoing.

         (ii) No purchase or transfer of a Junior Subordinate Certificate shall
be made by or to a Plan unless such purchaser or transferee is an "insurance
company general account" (within the meaning of PTCE 95-60) and is eligible for,
and satisfies all of the requirements for exemptive relief under Sections I and
III of PTCE 95-60. Each Person who acquires a Junior Subordinate Certificate or
any interest therein shall be deemed to certify and shall be required by the
Certificate Registrar to provide an Officer's Certificate (substantially in the
form of Exhibit L attached hereto) signed by a Responsible Officer of such
Person, which Officer's Certificate shall not be an expense of any Servicer, the
Trustee, the Certificate Administrator, if any, the Certificate Registrar or the
Depositor) that it meets the foregoing conditions, and that it will not transfer
such Certificate in violation of the foregoing.

         (e) 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 this Section 5.1(e) or Section
5.1(f). 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 following
provisions of this 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 this Section 5.1(e) unless such transfer is made pursuant to an effective
registration statement under the Securities Act or unless the Trustee or the
Certificate Registrar, if not the same Person as the Trustee, is 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 or the Certificate Registrar's, as applicable,
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 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

                                      -100-

<PAGE>

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,
any Servicer, the Certificate Administrator, 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, any Servicer, the
Certificate Administrator, 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 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, any Servicer, the Certificate Administrator, if
any, 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, any Servicer, the Certificate Administrator,
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.

         Section 5.2 CERTIFICATES ISSUABLE IN CLASSES; DISTRIBUTIONS OF
PRINCIPAL AND INTEREST; AUTHORIZED DENOMINATIONS. The aggregate principal amount
of Certificates that may be authenticated and delivered under this Agreement is
limited to the aggregate Principal Balance of the Loans as of the Cut-Off Date,
as specified in the Preliminary Statement to this Agreement, except for
Certificates authenticated and delivered upon registration of transfer of, or in
exchange for, or in lieu of, other Certificates pursuant to Section 5.3. Such
aggregate principal amount shall be allocated among one or more Classes having
designations, types of interests, initial per annum

                                      -101-

<PAGE>

Remittance Rates, initial Class Principal Balances and last scheduled
Distribution Dates as specified in the Preliminary Statement to this Agreement.
The aggregate Percentage Interest 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 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. The Trustee hereby appoints LaSalle Bank National Association as
the initial Certificate Registrar.

         Upon surrender for registration of transfer of any Certificate to the
Trustee at the office of First Trust of New York, National Association, 100 Wall
Street, Suite 1600, New York, New York 10005, or such other address or agency as
may hereafter be provided to the Certificate Administrator, if any, and the
related 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

                                      -102-

<PAGE>

Certificate, and there is delivered to the Trustee or any Authenticating Agent
such security or 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 Certificate
Administrator, the Servicers, 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
Certificate Administrator, if any, the Servicers, the Trustee, the Certificate
Registrar, nor any agent of the Depositor, the Certificate Administrator, if
any, the Servicers 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 or Authenticating Agent'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 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 Certificate Administrator, if any, and 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

                                      -104-

<PAGE>

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-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 Certificate Administrator, if any, or 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
or the Certificate Administrator is unable to locate a qualified successor, (b)
the Depositor, at its option, advises the Certificate Administrator, if any, or
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
Certificate Administrator, if any, or 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 Certificate
Administrator, if any, 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, the Certificate
Administrator, if any, and the Trustee, the Certificate Administrator, the
Certificate Registrar and the Paying Agent shall recognize the Holders of
Definitive Certificates as Certificateholders hereunder.

                         THE DEPOSITOR AND THE SERVICERS

         Section 6.1 LIABILITY OF THE DEPOSITOR AND THE SERVICERS. The Depositor
and the Servicers 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 related Servicer herein.

         Section 6.2 MERGER OR CONSOLIDATION OF THE DEPOSITOR OR THE SERVICERS.
Subject to the following paragraph, the Depositor and the Servicers 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 enforceability of this Agreement, the Certificates or any of the
Loans and to perform its respective duties under this Agreement.

         The Depositor or each 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 the related Servicer shall be a party, or any Person
succeeding to the business of the Depositor or the related Servicer, shall be
the successor of the Depositor or the related 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; provided,
however, that the successor or surviving Person to the related Servicer to the
extent the related Servicer has any obligations to service the Loans hereunder
(and it has not assigned such obligations pursuant to Section 3.1(c)), the Loans
shall be serviced by a FNMA approved lender or a FHLMC seller/servicer in good
standing; and provided further that the then-current rating of the Class A
Certificates will not be reduced as a result of such merger or consolidation.

         Section 6.3 LIMITATION ON LIABILITY OF THE SERVICERS AND OTHERS.
Neither the Servicers nor any of the directors, officers, employees or agents of
the Servicers 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 related 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. Each Servicer and any director, officer,
employee or agent of such 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. Each Servicer and any director, officer, employee or
agent of such 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 related Servicer and any director,
officer, employee or agent of the related 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

                                      -106-

<PAGE>

obligations and duties hereunder. Each 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 related 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 related 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 SERVICERS NOT TO RESIGN. Each Servicer agrees not to resign
from the obligations and duties hereby imposed on it, except upon determination
that its duties hereunder are no longer permissible under applicable law or are
in material conflict by reason of applicable law with any other activities
carried on by it, the other activities of the related Servicer so causing such a
conflict being of a type and nature carried on by the related Servicer at the
date of this Agreement. Any such determination permitting the resignation of a
Servicer shall be evidenced by an Opinion of Counsel to such effect delivered to
the Trustee. The related Servicer shall notify each Rating Agency of any such
resignation. No such resignation shall become effective until a successor
servicer shall have assumed the related Servicer's responsibilities and
obligations in accordance with Section 7.5 hereof.

         Notwithstanding the limitations stated above, each Servicer may
transfer its obligations, duties and rights hereunder without the consent of the
Certificateholders, provided, that (i) the related Servicer obtains the prior
written consent of each Rating Agency, (ii) the transferee is a FNMA or
FHLMC-approved servicer having a net worth of not less than $15,000,000, (iii)
the successor servicer assumes all of the related Servicer's responsibilities
and obligations in accordance with Section 7.5 hereof, (iv) the then-current
rating of the Class A Certificates will not be reduced as a result of such
transfer, and (v) the successor servicer has, in the reasonable opinion of the
Trustee, the qualifications, resources and experience to properly carry out,
observe and perform the duties, obligations and responsibilities of the related
Servicer hereunder; provided, that the foregoing clause (v) is intended solely
for the benefit of (and may be exercised or waived at the sole discretion of)
the Trustee, to enable the Trustee to assure itself that any successor Servicer
has such acceptable qualifications, resources and experience, and such clause
(v) is not intended to be for the benefit of, and shall not be relied upon or
enforced by, any Certificateholder, and provided, further, that any consent to
such transfer will not be unreasonably withheld by the Trustee. The foregoing
shall not limit the ability of each Servicer to enter into sub-servicing
agreements with third parties.

         Section  6.5      TRUSTEE ACCESS.

         Each Servicer shall afford the Depositor and the Trustee, upon
reasonable notice, during normal business hours access to all records maintained
by the related Servicer, in respect of its rights and obligations hereunder and
access to such of its officers as are responsible for such obligations. Upon
reasonable request, the related Servicer, shall furnish the Depositor and the
Trustee with its

                                      -107-

<PAGE>

most recent financial statements (or, for so long as WMMSC is a Servicer
hereunder, the most recent consolidated financial statements of Washington
Mutual, Inc., or the entity with whose financial statements the financial
statements of WMMSC 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.

                                     DEFAULT

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

                  (i) any failure by such 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 such Servicer by the Trustee
         or to such 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 such Servicer duly to observe
         or perform in any material respect any other of the covenants or
         agreements on the part of such 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 such Servicer by the Trustee, or to
         such 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 related Servicer and such decree or order shall
         have remained in force undischarged or unstayed for a period of 60
         days;

                  (iv) such 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 such
         Servicer or of or relating to all or substantially all of its property;

                  (v) such Servicer shall admit in writing its inability to pay
         its debts generally as they become due, file a petition to take
         advantage of any applicable insolvency or reorganization statute, make
         an assignment for the benefit of its creditors or voluntarily suspend
         payment of its obligations; or

                                      -109-

<PAGE>

                  (vi) any failure of such 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 related Servicer (and to the Trustee if given by the
Certificateholders) may terminate all of the rights and obligations of such
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 a
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 which 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 related Servicer, which shall be telecopied to such Servicer,
immediately terminate all of the rights and obligations of such Servicer, under
this Agreement and in and to the Loans and the proceeds thereof. On or after the
receipt by such Servicer of such written notice, all authority and power of such
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 such 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 such Servicer.
Each Servicer agrees to cooperate with the Trustee in effecting the termination
of such 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 all amounts which then
have been or should have been deposited in the Custodial Account for P&I by the
related 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 related Servicer and the Trustee shall give each
Rating Agency notice of any Event of Default. If a Servicer shall within two
Business Days following such suspension remit to the Trustee the amount of any
Advance the nonpayment of which by such 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 related Servicer to resume its
rights and obligations as a Servicer hereunder. Each 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. Each 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 related Servicer
to resume its rights and obligations as a 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 related 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 A SERVICER AND UPON EVENT
OF DEFAULT. In the event that the Trustee shall have knowledge of any failure of
a Servicer specified in Section 7.1(i) or (ii) which would become an Event of
Default upon the related Servicer's failure to remedy the same after notice, the
Trustee shall give notice thereof to such 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 related Servicer as specified in Section 7.1(i)
and (ii) or any Event of Default unless notified thereof in writing by the
related Servicer or by a Certificateholder.

         Section  7.5      APPOINTMENT OF SUCCESSOR SERVICER.

                                      -111-

<PAGE>

         (a) When a Servicer receives a notice of termination pursuant to
Section 7.1 or the Trustee receives the resignation of a Servicer evidenced by
an Opinion of Counsel pursuant to Section 6.4, the Trustee shall become the
successor in all respects to the related Servicer in its capacity as a 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 related Servicer by the
terms and provisions hereof and in its capacity as such successor shall have the
same limitation of liability herein granted to such 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
applicable Servicing Fee as agreed by the Trustee and the related Servicer,
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 applicable Servicing Fee, the excess shall be
paid to the Class R Certificateholder. If the Trustee and the related Servicer
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 applicable 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 related Servicer
make the Trustee liable for any actions or omissions of such Servicer in its
capacity as a 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 a 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
applicable Servicer hereunder in the assumption of all or any part of the
responsibilities, duties or liabilities of the related 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
applicable Servicing Fee 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

                                      -112-

<PAGE>

announcement shall specify that the successor servicer shall be entitled to the
full amount of the applicable 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 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 related 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
Certificateholder at the time of such sale, transfer and assignment to the
related Servicer's successor.

         (c) In the event that a Servicer resigns or is terminated in accordance
with the terms of this Agreement, such Servicer agrees to cooperate with the
Trustee and any successor servicer in effecting the termination of such
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 such 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 such 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 related Servicer to deliver, or any
delay in delivering, cash, documents or records to it.

         Section 7.6 NOTIFICATION TO CERTIFICATEHOLDERS. Upon any termination of
a Servicer or appointment of a successor to such 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.

                             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 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
related 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

                                      -114-

         Balance of all Certificates or 51% of the aggregate Certificate
         Principal Balance of any Class of 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 either Servicer (except for its own acts or
         omissions as successor 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; and

                  (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,
         assessment, or other governmental charge or any lien or 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 a 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.

         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 a 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, a
Servicer in accordance with the terms of this Agreement.

         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;

                  (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 or non-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

                                      -116-

<PAGE>

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 related Servicer in respect
of the Loans or deposited in or withdrawn from the Custodial Account for P&I by
the related 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 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 Trustee and any director, officer, employee or
agent of the Trustee shall be indemnified by the Depositor and held harmless
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, 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 Affiliate
or 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.

                                      -117-

<PAGE>

         Section 8.6 SERVICER TO PAY TRUSTEE'S FEES AND EXPENSES. Each 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, and the related Servicer shall pay
or reimburse the Trustee upon its request for all reasonable 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 related 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 Servicers nor be a
parent of or a subsidiary of a 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 a Servicer. Such notice shall also be furnished to each
Rating Agency. Upon receiving such notice of resignation, a 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

                                      -118-

<PAGE>

petition any court of competent jurisdiction for the appointment of a successor
trustee at the expense of the related Servicer.

         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 a 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, a 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 related 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 each Servicer
and to its predecessor trustee an instrument accepting such appointment
hereunder, and thereupon the resignation or removal of the predecessor trustee
shall become effective, and such successor trustee, without any further act,
deed or conveyance, shall become fully vested with all the rights, powers,
duties and obligations of its predecessor hereunder, with like effect as if
originally named as trustee herein. The predecessor trustee shall 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 each 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, each 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 a Servicer fails

                                      -119-

<PAGE>

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 related 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, each
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 related
Servicer and the Trustee may consider necessary or desirable. If the related
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 and 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.

         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 any 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

                                      -120-

<PAGE>

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 related 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 or Standard
Federal Bank, N.A. Any Custodian appointed shall be (i) LaSalle Bank National
Association or (ii) Standard Federal Bank, N.A., or (iii) (a) an institution
subject to supervision by federal or state authority, (b) shall have combined
capital and surplus of at least $50,000,000 and (c) 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 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
each Servicer and have a principal office and place of business in 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

                                      -121-

<PAGE>

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
Servicers. 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 Servicers. 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
Servicers 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 Trustee or the Certificate Administrator, if any, 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 Trustee will provide updated Data to Bloomberg
on or before each Distribution Date.

         Section 8.15 CALCULATION OF LIBOR. Until the Certificate Principal
Balance of each of the Adjustable Rate Certificates has been reduced to zero,
LIBOR for the initial Interest Accrual Period shall be 1.32%, and for any
Interest Accrual Period thereafter, the Trustee, if any, shall establish LIBOR
on each LIBOR Determination Date as follows:

         (a) If on such LIBOR Determination Date a rate for United States dollar
deposits for one month appears on the Dow Jones Telerate System, page 3750,
LIBOR for the next Interest Accrual Period shall be equal to such rate as of
11:00 a.m., London time;

         (b) If such rate does not appear on such page (or such other page as
may replace that page on that service, or if such service is no longer offered,
such other service for displaying LIBOR or comparable rates as may be selected
by the Trustee, if any, after consultation with the Servicers), the rate shall
be determined as follows:

                  (i) The Trustee on the LIBOR Determination Date will request
         the principal London offices of each of four major reference banks in
         the London interbank market, as

                                      -122-

<PAGE>

         selected by the Trustee, to provide the Trustee with its offered
         quotation for deposits in United States dollars for the upcoming
         one-month period, commencing on the second LIBOR Business Day
         immediately following such LIBOR Determination Date, to prime banks in
         the London interbank market at approximately 11:00 a.m. London time on
         such LIBOR Determination Date and in a principal amount that is
         representative for a single transaction in United States dollars in
         such market at such time. If at least two such quotations are provided,
         LIBOR determined on such LIBOR Determination Date will be the
         arithmetic mean of such quotations.

                  (ii) If fewer than two quotations are provided, LIBOR
         determined on such LIBOR Determination Date will be the arithmetic mean
         of the rates quoted at approximately 11:00 a.m. in New York City on
         such LIBOR Determination Date by three major banks in New York City
         selected by the Trustee for one-month United States dollar loans to
         leading European banks, in a principal amount that is representative
         for a single transaction in United States dollars in such market at
         such time; PROVIDED, HOWEVER, that if the banks so selected by the
         Trustee are not quoting as mentioned in this sentence, LIBOR determined

                                   TERMINATION

         Section 9.1 TERMINATION UPON PURCHASE BY THE SERVICERS OR LIQUIDATION
OF ALL LOANS. The respective obligations and responsibilities of the Servicers
and the Trustee created hereby (other than the obligation to make payments to
Certificateholders as hereafter set forth in this Section 9.1 and obligations to
the Trustee in Sections 8.4 and 8.6) 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 related
Servicer of all related Loans at a price equal to the sum of (a) the principal
balance of each Loan plus accrued interest thereon at the applicable Mortgage
Interest Rate to, but not including, the next scheduled Due Date, and (b) the
fair market value of all acquired property in respect of Loans, such fair market
value to be determined by an appraiser selected by the Trustee; PROVIDED,
HOWEVER, that in no event shall the trust created hereby continue beyond the
expiration of 21 years from the death of the last survivor of the descendants of
Joseph P. Kennedy, the late ambassador of the United States to the Court of St.
James, living on the date hereof; and provided, further, that a "plan of
liquidation" of each of REMIC I, REMIC II and REMIC III in accordance with
Section 860F of the Code must be adopted in conjunction with any termination
effected pursuant to subclauses (i) or (ii) of this Section 9.1.

         WMMSC and AAMG are hereby granted the right to purchase the Group I
Loans and Group II Loans, respectively, pursuant to clause (ii) above, PROVIDED,
HOWEVER, that such right shall be conditioned upon (a) the Principal Balances of
such Group I Loans or Group II Loans, as applicable, at the time of any such
purchase, aggregating an amount less than 5% of the aggregate Principal Balance
of the Group I Loans and Group II Loans, respectively, on the Cut-off Date,
after deduction of payments due on or before such date, and (b) the aggregate
price in clause (ii) above must be not greater than the aggregate fair market
value of the related Loans and all such acquired property.

         Notice of any termination pursuant to clause (i) or (ii) above,
specifying the Distribution Date upon which all Certificateholders may surrender
their Certificates to the Trustee or its agent for payment and cancellation,
shall be given promptly by the Trustee or its agent (upon direction by the
related Servicer no less than 10 days prior to the date such notice is to be
mailed) by letter to Certificateholders and each Rating Agency mailed by first
class mail no later than the 25th day of the month preceding the month of such
final distribution specifying (i) the Distribution Date upon which final payment
on the Certificates will be made upon presentation and surrender of Certificates
at the office or agency of the Trustee or the Certificate Registrar therein
designated, (ii) the amount of any such final payment and (iii) that the Record
Date otherwise applicable to such Distribution Date is not applicable, payments
being made only upon presentation and surrender of the Certificates at the
office or agency of the Trustee or the Certificate Registrar therein specified.
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 the related

                                      -124-

<PAGE>

Servicer's election to purchase, such 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 related 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 related 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 related 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 a related Servicer or both Servicers, as applicable,
exercises its purchase option as provided in Section 9.1 to repurchase all of
the Loans in a related Loan Group, REMIC I, REMIC II or the Trust Fund and each
of REMIC I, REMIC II and REMIC III, as applicable, shall be terminated in
accordance with the following additional requirements, unless the Trustee and
the Certificate Administrator have 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, REMIC II or REMIC III of the Trust Fund as described
in Section 860F(a)(2) of the Code, or (ii) cause any of REMIC I, REMIC II or
REMIC III of the Trust Fund to fail to qualify as a REMIC at any time that any
Certificates are outstanding:

                  (i) Within 90 days prior to the final Distribution Date set
         forth in the notice given by the Depositor under Section 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, REMIC II and
         REMIC III in the case of a repurchase of all of the Loans, or shall
         adopt a plan of complete liquidation of REMIC I in the case of a
         repurchase of all of the Group I Loans, or

                                      -125-

<PAGE>

         shall adopt a plan of complete liquidation of REMIC II in the case of a
         repurchase of all the Group II Loans (a plan of complete liquidation of
         REMIC III shall be adopted at the time of the repurchase of the second
         of the Loan Groups to be repurchased); and

                  (ii) At or after the time of adoption of such a plan of
         complete liquidation and at or prior to the final Distribution Date,
         the related Servicer as agent of the Trustee shall sell all of the
         assets of REMIC I, REMIC II or the Trust Fund, as applicable, 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 liquidation but prior
         to the final Distribution Date, such 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 plans of
complete liquidation and to take such other action in connection therewith as
may be reasonably requested by the related Servicer.

                            MISCELLANEOUS PROVISIONS

         Section 10.1 AMENDMENT. This Agreement may be amended from time to time
by the Depositor, any 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 three
REMICs 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 January 23, 2003,
together with the Prospectus Supplement dated May 27, 2003.

         This Agreement may also be amended from time to time by the Depositor,
any Servicer and the Trustee with the consent of the Holders of Certificates
evidencing, in aggregate, not less than 66- 2/3% of each Class of Certificates
affected thereby 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 of such Class; 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

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 Holder of the Class R Certificate shall have no right to vote at
all times that any Class A Certificates or Subordinate 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 three REMICs.

         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

                                      -127-

<PAGE>

effect that such amendment will not cause any of REMIC I, REMIC II or REMIC III
of the Trust Fund to fail to qualify as a REMIC at any time that any REMIC I
Regular Interests or REMIC II Regular Interests or REMIC III 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

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 a
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.

         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 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

                                      -128-

<PAGE>

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.

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

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

Transfer is not so exempt or is not made in accordance with such federal and
state laws.

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
transferee (x) is not an employee benefit plan or other plan or arrangement
subject to the prohibited transaction provisions of ERISA or Section 4975 of the

legend setting forth the applicable restrictions on transfer.

         Re:   ABN AMRO Mortgage Corporation Mortgage Pass-Through Certificates,
               Series 2003-6 Class R

         This letter is delivered to you in connection with the sale by
_______________________ (the "Seller") to _______________________ (the
"Purchaser") of $_______________________ initial Certificate Principal Balance
of Mortgage Pass-Through Certificates, Series 2003-6, Class R (the
"Certificate"), pursuant to Section 5.1 of the Pooling and Servicing Agreement
(the "Pooling and Servicing Agreement"), dated as of May 1, 2003 among ABN AMRO
Mortgage Corporation, as depositor (the "Company"), ABN AMRO Mortgage Group,
Inc., as a servicer ("AAMG"), Washington Mutual Mortgage Securities Corp. as a
servicer ("WMMSC" and together with AAMG, the "Servicers"), and JPMorgan Chase
Bank, as trustee (the "Trustee"). All terms used herein and not otherwise
defined shall have the meanings set forth in the Pooling and Servicing
Agreement. The Seller hereby certifies, represents and warrants to, and
covenants with the Depositor, the Servicers, the Certificate Registrar and the
Trustee that:

         1. No purpose of the Seller relating to the sale of the Certificate by
the Seller to the Purchaser is or will be to enable the Seller to impede the
assessment or collection of tax.

         2. The Seller understands that the Purchaser has delivered to the
Trustee, the Servicers, the Certificate Registrar and the Depositor a transferee
affidavit and agreement in the form attached to the Pooling and Servicing
Agreement as Exhibit J. The Seller does not know or believe that any
representation contained therein is false.

         3. The Seller has no actual knowledge that the Proposed Transferee is
not a Permitted Transferee.

         4. The Seller has no actual knowledge that the Purchaser would be
unwilling or unable to pay taxes due on its share of the taxable income
attributable to the Certificates.

<PAGE>

         5. At the time of this transfer (i) the Seller has conducted a
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
(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 rate 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 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]

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 the 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
the 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 the 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 the 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

<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 the 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 the Class R Certificate and the provisions of Section 5.1 of the Pooling and
Servicing Agreement under which the Class R Certificate was 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 the 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 the 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/

1/Bracketed text to be included if the Owner is relying on the transferee's
compliance with the "Asset Test Safe Harbor" (which is generally described as
the second "safe harbor" in the Prospectus Supplement) rather than the "Formula
Test Safe Harbor" (which is generally described as the first "safe harbor" in
the Prospectus Supplement). See "Federal Income Tax Consequences--Special Tax
Considerations Applicable to the Residual Certificate" in the

<PAGE>

         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, REMIC II or the REMIC III.

         15. The Owner hereby agrees that it will not take any action that could
endanger the REMIC status of the REMIC I, REMIC II or the REMIC III, as
applicable, or result in the imposition of tax on the REMIC I, REMIC II or the
REMIC III 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 the Class R Certificate has represented
to their transferor that, if the 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 the 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/

         IN WITNESS WHEREOF, the Owner has caused this instrument to be executed
on its behalf, pursuant to the authority of its Board of Directors, by its
[Title of Officer] and its corporate seal to be hereunto attached, attested by

                     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, 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, ABN AMRO Mortgage Group, Inc., as a servicer ("AAMG"),
Washington Mutual Mortgage Securities Corp. as a servicer ("WMMSC" and together
with AAMG, the "Servicers"), and JPMorgan Chase Bank, 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.

         Unless the certificate of authentication hereon has been executed by or

                          ABN AMRO MORTGAGE CORPORATION
                        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 related Servicer is obligated to advance its own funds to
cover certain shortfalls with respect to payments on the related Loans. In the
event Servicer funds are advanced with respect to any Loan, such advance is
reimbursable to the related 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 related Servicer from time to time for
purposes other than distributions to Certificateholders, such purposes including
reimbursement to such 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 applicable 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.

<PAGE>

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

<PAGE>

         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 Certificate
Administrator, the Servicers, 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
Certificate Administrator, the Servicers, the Trustee nor any such agent shall
be affected by notice to the contrary.

         The respective obligations and responsibilities of the Servicers 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 a Servicer of all related 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.

manner, or taken any other action, that would constitute a distribution of the

violation of Section 5 of the 1933 Act or require registration pursuant thereto,
and that the Seller has not offered the Rule 144A Securities to any person other
than the Buyer or another "qualified institutional buyer" as defined in Rule

                              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:

                                   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 2.01 [Approval of _______________ as an Approved Servicer under
the Servicer Guide.

         The Company hereby approves _______________ as an approved servicer for
all purposes under the terms of the Servicer Guide.]

         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)

<PAGE>

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.

<PAGE>

         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,

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.

<PAGE>

         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
necessary or appropriate to effect the purposes of such notice of termination,
whether to complete the transfer and endorsement or assignment of the affected
Specially Serviced Mortgage Loans and related documents, or otherwise. The
Special Servicer agrees to cooperate with the Company in implementing the
termination of the Special Servicer's responsibilities and rights hereunder,

agent for administration by it of all amounts in the possession of the Special
Servicer or thereafter be received with respect to the Specially Serviced
Mortgage Loans and the transfer of the] servicing rights back to the Company.

notice to the Company and the Special Servicer appoint a successor special
servicer having the characteristics set forth in clauses (i), (ii) and (iii)
below, and which shall succeed to all rights and assume all of the
responsibilities, duties and liabilities of the Special Servicer under this
Agreement simultaneously with the termination of the Special Servicer's
responsibilities, duties and liabilities under this Agreement. In the event that
the Special Servicer's duties, responsibilities and liabilities under this
Agreement should be terminated pursuant to the foregoing, the Special Servicer
shall discharge such duties and responsibilities during the period from the date
it acquires knowledge of such termination until the effective date thereof with
the same degree of diligence and prudence which it is obligated to exercise
under this Agreement, and shall take no action whatsoever that might impair or
prejudice the rights or financial condition of its successor. The removal of the
Special Servicer shall not become effective until a successor shall be appointed
pursuant to this Section and shall in no event relieve the Special Servicer of
the representations and warranties made pursuant to Section 4.03 and the
remedies available to the Class B Holder and/or the Company under Sections 4.04
and 5.01, it being understood and agreed that the provisions of such Sections
4.04 and 5.01 shall be applicable to the Special Servicer notwithstanding any
such termination of it, or the termination of this Agreement.

net worth of not less than $1,000,000][meet the eligibility requirements of an
approved servicer under the Company's Servicer Guide], (ii) the appointment of
such successor servicer will not result in the downgrading in any rating by any
applicable rating agency of any security issued in connection with the
applicable Pooling and Servicing Agreements, and (iii) have and keep in full

provided herein shall execute, acknowledge and deliver to the Class B Holder and
the Company an instrument accepting such appointment, wherein the successor
shall make the representations and warranties set forth in Section 4.03,
whereupon such successor shall become fully vested with all the rights, powers,
duties, responsibilities, obligations and liabilities of the Special Servicer,
with like effect as if originally named as a party to this Agreement.

         Within 30 days of the appointment of a successor special servicer by
the Class B Holder, the Special Servicer shall prepare, execute and deliver to
the successor entity any and all documents and other instruments, place in such
successor's possession all servicing files related to the Specially Serviced
Mortgage Loans, and do or cause to be done all other acts or things necessary or
appropriate to effect the purposes of such notice of termination [, including
but not limited to the transfer and endorsement of the related Mortgage Notes
and other documents, and the Class B Holder shall do or cause to be done the
preparation and recordation of Assignments of Mortgage and Deeds at the Class B

such rights, powers, duties, responsibilities, obligations and liabilities of
the Special Servicer.

shall send, or shall cause the related servicer to send, to the Class B Holder
all other written reports, documentation, instruments, certificates and
correspondences provided by a servicer under the terms of the Servicer Guide
with respect to any Mortgage Loan that becomes sixty (60) days or more
delinquent.

         (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

<PAGE>

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.

<PAGE>

         (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

<PAGE>

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

                        --------------------------------

          Mortgage Loan Purchase Agreement (the "AGREEMENT"), dated as of May
28, 2003 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 retained 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 May 1, 2003 (the "CUT-OFF DATE") of
approximately $500,669,016 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 May
28, 2003 (the "CLOSING DATE") at the office of Purchaser's counsel in New York,
New York 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 one or more obligors (each
a "MORTGAGOR") and the related 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

<PAGE>

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.

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 * % multiplied by the
principal balance thereof as of the Cut-Off Date plus any accrued and unpaid
interest thereon from the Cut-Off Date to the Closing Date.

* Provided upon request by ABN AMRO Mortgage Corporation.

     (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.

     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

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

     limited to, usury, equal credit opportunity, truth-in-lending and
     disclosure laws, and each Mortgage Loan was not usurious at the time of
     origination;

          (vii) to the best of the Seller's knowledge, all insurance premiums,

     previously due and owing with respect to each Mortgaged Property have been
     paid and all taxes and governmental assessments previously due and owing,

     subject only to (a) the lien of current real property taxes and assessments
     not yet due and payable, (b) covenants, conditions and restrictions, rights
     of way, easements and other matters of public record as of the date of

     to the best of the Seller's knowledge, no event which, with the passage of
     time or with notice and the expiration of any grace or cure period, would
     constitute a default, breach, violation or event of acceleration; and the
     Seller has not waived any default, breach, violation or event of
     acceleration;

          (xiv) that each Mortgage Loan was originated on FNMA or FHLMC uniform
     instruments for the state in which the Mortgaged Property is located;

          (xv) that based upon a representation by each Mortgagor at the time of

     95.63% of the Mortgage Loans measured by principal balance were to be
     secured by owner-occupied residences and approximately 4.37% of the
     Mortgage Loans measured by principal balance were secured by owner-occupied
     second home residences;

          (xvi) that an appraisal of each Mortgaged Property was conducted at
     the time of origination of the related Mortgage Loan, and that each such
     appraisal was conducted in accordance with FNMA or FHLMC criteria, on FNMA
     or FHLMC forms and comparables on at least three properties were obtained;

                                       -7-

<PAGE>

          (xvii) that no Mortgage Loan had a Loan-to-Value Ratio at origination
     in excess of 95.00%;

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

          (xix) each Mortgage Loan was either (A) originated directly by or
     closed in the name of either: (i) a savings and loan association, savings
     bank, commercial bank, credit union, insurance company, or similar
     institution which is supervised and examined by a federal or state
     authority or (ii) a mortgagee approved by the Secretary of Housing and
     Urban Development pursuant to Sections 203 and 211 of the National Housing
     Act or (B) originated or underwritten by an entity employing underwriting
     standards consistent with the underwriting standards of an institution as
     described in subclause (A)(i) or (A)(ii) above;

          (xx) 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;

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

          (xxii) pursuant to the terms of the applicable Mortgage, all buildings
     or other improvements upon each Mortgaged Property are insured by an
     insurer acceptable to FNMA or FHLMC against loss by fire, hazards of
     extended coverage and such other hazards as are customary in the area where
     the Mortgaged Property is located pursuant to insurance policies conforming
     to the requirements of FNMA or FHLMC. If upon origination of any Mortgage
     Loan, the Mortgaged Property was in an area identified in the Federal
     Register by the Federal Emergency Management Agency as having special flood
     hazards (and such flood insurance has been made available) a flood
     insurance policy meeting the requirements of the current guidelines of the
     Federal Insurance Administration is in effect which policy conforms to the
     requirements of FNMA or FHLMC. All individual insurance policies contain a
     standard mortgagee clause naming the Seller and its successors and assigns
     as mortgagee, and all premiums thereon have been paid. Each Mortgage
     obligates the Mortgagor thereunder to maintain the hazard insurance policy
     at the Mortgagor's cost and expense, and on the Mortgagor's failure to do
     so, authorizes the holder of the Mortgage to obtain and maintain such
     insurance at such Mortgagor's cost and expense, and to seek reimbursement
     therefor from the Mortgagor. Where required by state law or regulation, the
     Mortgagors have been given an opportunity to choose the carrier of the
     required hazard insurance policy, provided the policy is not a "master" or
     "blanket" hazard insurance policy covering the common facilities of a
     planned unit development. The hazard insurance policy is the valid and
     binding obligation of the insurer, is in full force and effect, and will be
     in full force and effect and inure to the benefit of the Purchaser upon the
     consummation of the transactions contemplated

                                       -8-

<PAGE>

     by this Agreement. Seller has not engaged in, and has no knowledge of the
     Mortgagor's or any subservicer s having engaged in, any act or omission
     which would impair the coverage of any such policy, the benefits of the
     endorsement provided for herein, or the validity and binding effect of
     either, including, without limitation, no unlawful fee, commission,
     kickback or other unlawful compensation or value of any kind has been or
     will be received, retained or realized by any attorney, firm or other
     person or entity, and no such unlawful items have been received, retained
     or realized by the Seller. All flood insurance and hazard insurance
     premiums have been paid when due;

          (xxiii) each Mortgage Loan has been closed and the proceeds of the
     Mortgage Loan have been fully disbursed and there is no requirement for
     future advances thereunder, and any and all requirements as to completion
     of any on-site or off -site improvement and as to disbursements of any
     escrow funds therefor have been complied with. All costs, fees and expenses
     incurred in making or closing each Mortgage Loan and the recording of the
     related Mortgage were paid, and the applicable Mortgagor is not entitled to
     any refund of any amounts paid or due under the Mortgage Note or Mortgage;

          (xxiv) with respect to each Mortgage Loan with a Loan-to-Value Ratio
     greater than 80%, the excess of the principal balance of such Mortgage Loan
     to the percentage of the appraised value thereof specified by FNMA is and
     will be insured as to payment defaults by a primary mortgage insurance
     policy issued by an insurer, and in a form, acceptable to FNMA or FHLMC.
     All provisions of such primary mortgage insurance policy have been and are
     being complied with, such policy is in full force and effect, and all
     premiums due thereunder have been paid. No action, inaction or event has
     occurred and no state of facts exists that has, or will result in the
     exclusion from, denial of, or defense to coverage. Any Mortgage Loan
     subject to a primary mortgage insurance policy obligates the Mortgagor
     thereunder to maintain the primary mortgage insurance policy and to pay all
     premiums and charges in connection therewith. The mortgage interest rate
     for the Mortgage Loan as set forth on the Mortgage Loan Schedule is net of
     any such insurance premium;

          (xxv) to the best of the Seller's knowledge each Mortgaged Property is
     free from any and all toxic or hazardous substances and there exists no
     violation of any local, state or federal environmental law, rule or
     regulation;

          (xxvi) all inspections, licenses and certificates required to be made
     or issued with respect to all occupied portions of each Mortgaged Property
     and, with respect to the use and occupancy of the same, including, but not
     limited to, certificates of occupancy and fire underwriting certificates,
     have been made or obtained from the appropriate authorities;

          (xxvii) each Mortgage Loan has been properly serviced in accordance
     with all applicable federal, state and local laws, the terms of the
     Mortgage, Mortgage Note and related Mortgage Loan documents and all
     applicable guidelines to any prior mortgagee. With respect to escrow
     deposits and escrow payments, all such payments are in the possession of

                                       -9-

<PAGE>

     the Seller and there exist no deficiencies in connection therewith for
     which customary arrangements for repayment thereof have not been made. All
     escrow payments have been collected in full compliance with state and
     federal law. An escrow of funds is not prohibited by applicable law and has
     been established in accordance with law, and by Servicer's best estimate in
     an amount sufficient to pay for every item which remains unpaid and which
     has been assessed but is not yet due and payable. No escrow deposits or
     escrow payments or other charges or payments due the Seller have been
     capitalized under any Mortgage or any Mortgage Note. Any interest required
     to be paid pursuant to state and local law has been properly paid and
     credited;

          (xxviii) the Mortgage Loan will have a transferable life-of-loan tax
     service contract with First American Real Estate Tax Service or another tax
     service, provided that such tax service is acceptable to the Purchaser;

          (xxix) Each Mortgage Note and Assignment of Mortgage has been, or will
     be, delivered to the Purchaser or its custodian for each Mortgage Loan;

          (xxx) the Mortgage Loan was underwritten in accordance with the
     Seller's underwriting standards in effect at the time the Mortgage Loan was
     originated; and

          (xxxi) no fraud occurred on the part of the Seller, the Mortgagor or,
     to the best of the Seller's knowledge, any third party in connection with
     the origination of the Mortgage Loan.

     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 (except for a breach of that portion of the representation and
warranty relating to any casualty from the presence of hazardous waste or
hazardous substances), (ii) repurchase such Mortgage Loan or Mortgage Loans (or
any property acquired in respect thereof) from the Purchaser at a purchase price
in an amount equal to par plus accrued interest up to the date of repurchase 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

                                      -10-

<PAGE>

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"). 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 purchase price
in an amount equal to par plus accrued interest up to the date of repurchase 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, free and clear of all security interests, liens
and other encumbrances created by this Agreement, 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.

SECTION 9. REPRESENTATIONS, WARRANTIES AND AGREEMENTS OF PURCHASER.

     The Purchaser hereby represents and warrants to the Seller, as of the date
hereof (or such other date as is specified in the related representation or
warranty) as follows:

the laws of the State of Delaware;

     (b) The execution and delivery of this Agreement by the Purchaser and its
performance of and compliance with the terms of this Agreement will not violate

Purchaser or to which any property or assets of the Purchaser is subject;

     (c) The Purchaser has all requisite corporate power, authority and capacity
to enter into this Agreement and to perform the obligations required of it

                         PURSUANT TO SECTION 10(B)(IV)]
                                     -----------------

                        Mortgage Loan Purchase Agreement
                        --------------------------------

          Mortgage Loan Purchase Agreement (the "AGREEMENT"), dated as of May
28, 2003 between ABN AMRO Mortgage Group, Inc. (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 $198,264,572 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 May
28, 2003 (the "CLOSING DATE") at the office of Purchaser's counsel in New York,
New York 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 * % multiplied by the
principal balance thereof as of the Cut-Off Date plus any accrued and unpaid
interest thereon from the Cut-Off Date to the Closing Date.

* Provided upon request by ABN AMRO Mortgage Corporation.

     (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 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

                                       -2-

<PAGE>

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.

     (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 and the Trustee (as defined in the Pooling and
Servicing Agreement, dated as of May 1, 2003 (the "POOLING AND SERVICING
AGREEMENT"), among the Purchaser, as depositor, ABN AMRO Mortgage Group, Inc.,
as a servicer, Washington Mutual Mortgage Securities Corp., as a servicer and
JPMorgan Chase Bank, as trustee) 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, the
Purchaser or the Servicer (as defined in the Pooling and Servicing Agreement)
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.

                                       -3-

instruments (including, without limitation, any UCC financing statements) as may
be necessary, or 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,

     (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 may be necessary to

interest, each in form and substance satisfactory to the Purchaser; and the
Seller hereby grants to the Purchaser, subject to the satisfaction or waiver of
the conditions set forth in SECTION 11 hereof, the right, at the Purchaser's
option, to file any or all such financing statements, amendments, continuation
statements, assignments, certificates and other documents pursuant to the UCC
and otherwise without its signature and hereby irrevocably appoints the
Purchaser, subject to the satisfaction or waiver of the conditions set forth in
SECTION 11 hereof, as its attorney-in-fact to execute, deliver and file any such
financing statements, amendments, continuation statements, assignments,
certificates and other documents in the Seller's name and to perform all other
acts which the Purchaser deems appropriate to perfect or to maintain the
perfection of the security interest; and (ii) notify the Purchaser within five

     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,

          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 (except for a breach
     of that portion of the representation and warranty relating to any casualty
     from the presence of hazardous waste or hazardous substances), (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

                                       -8-

<PAGE>

     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 Purchase
     Price as adjusted for 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, free and clear of
     all security interests, liens and other encumbrances created by this
     Agreement, 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.

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;

     (d) The Purchaser 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

SECTION 12. INDEMNIFICATION.

any and all losses, claims, expenses, damages or liabilities to which Purchaser

liabilities (or actions in respect thereof) arise out of or are based upon any
representation or warranty made by the Seller in SECTION 8(A)(I) THROUGH SECTION
8(A)(VII) 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.

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

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.

     Re: ABN AMRO Mortgage Corporation Purchase of Mortgage Loans
         --------------------------------------------------------

Ladies and Gentlemen:

     As _______________ to ABN AMRO Mortgage Group, Inc., 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 May 28, 2003 (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 or verify, we have relied upon statements and
representations of officers and other representatives

<PAGE>

ABN AMRO Mortgage Corporation
__________ __, 200_
Page 2

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 no 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 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

<PAGE>

would be likely to materially impair the ability of Seller to perform under the
terms of the Purchase Agreement.

     The Opinions expressed herein are limited to matters of federal and
Michigan law and do not purport to cover any matters as to which laws of any
other jurisdiction are applicable. Except as expressly provided herein, this
opinion is being furnished to you solely for your benefit in connection with the
purchase of the Mortgage Loans, and it is not to be used, circulated, quoted or
otherwise referred to for any purpose without my express written consent.

                                         Sincerely,

                                         ABN AMRO Mortgage Group, Inc.
