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

          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.

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 (excluding the servicing rights related thereto) 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 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 (excluding the related servicing
rights) and the related Mortgage Note, the Mortgage and the contents of the
related Mortgage File shall be, upon satisfaction of SUBSECTION 3(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, Washington Mutual Mortgage
Securities Corp., as a servicer, ABN AMRO Mortgage Group, Inc., 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

promptly remitted to the Seller.

agrees to take or cause to be taken such further actions to execute, deliver and

acts which the Purchaser deems appropriate to perfect or to maintain the
perfection of the security interest; and (ii) notify the Purchaser within five

     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;

                                       -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-

     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-

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.

                         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.

SECTION 7. FURTHER ACTIONS; FINANCING STATEMENTS.

     (a) In furtherance of the provisions of SECTION 5(C) hereof, the Seller
agrees to take or cause to be taken such further actions to execute, deliver and
file or cause to be executed, delivered and filed, such further documents and
instruments (including, without limitation, any UCC financing statements) as 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,
and the Purchaser shall cooperate in any such action.

     (b) The Seller shall: (i) promptly execute, deliver, and file any financing
statements, amendments, continuation statements, assignments, certificates and
other documents with respect to such security interest as may be necessary to
enable the Purchaser to perfect or to maintain the perfection of such security
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
(5) days after the occurrence of any of the following: (A) any change in the
Seller's corporate name or any trade name; (B) any change in the Seller's

any merger or consolidation or other change in Seller's identity or material
change in its corporate structure.

          (x) neither the Seller nor any prior holder of any Mortgage has,
     except as the Mortgage File may reflect, modified the Mortgage in any
     material respect; satisfied, cancelled or subordinated such Mortgage in
     whole or in 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
     condominium form of ownership in real property;

          (xii) the condominium projects that include the condominiums that are

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

     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

     or FHLMC forms and comparables on at least three properties were obtained;

          (xvii) that no Mortgage Loan had a Loan-to-Value Ratio at origination
     in excess of 95%;

          (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;


                                       -7-

<PAGE>



          (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

     ss.1.860 G-2(f) of the REMIC provisions or any similar rule;

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

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

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

          Upon discovery by either the Seller, the Purchaser or its designees of
     a breach of any of the foregoing representations or warranties of the
     Seller which materially and adversely affects (1) the value of any of the
     Mortgage Loans actually delivered or (2) the interests of the Purchaser
     therein, the party discovering such breach shall give prompt written notice
     to the other. Within 90 (ninety) days of its discovery or its receipt of
     notice of any such breach of a representation or warranty, the Seller
     shall, with respect to the Mortgage Loan(s) to which such breach relates,
     either (i) cure such breach in all material respects (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
governmental agency, which the Purchaser default might have consequences that

operations of the Purchaser or its properties or might have consequences that

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

of the Purchaser's knowledge). This indemnity will be in addition to any
liability which the Purchaser may otherwise have.

     (c) Promptly after receipt by either the Purchasers or the Seller of notice
of the commencement of any action or proceeding in any way relating to or

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.
