Mortgage Loan Purchase Agreement

            Mortgage Loan Purchase Agreement (the "Agreement"), dated as of
February 27, 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:

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 $255,670,142 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
February 27, 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.

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.

3. Purchase Price.

      A. In exchange for the Mortgage Loans, on the Closing Date, the Purchaser
shall transfer to the Seller by wire transfer in immediately available funds the
purchase price (the "Purchase Price") which is equal to the principal balance
thereof as of the Cut-Off Date plus any accrued and unpaid interest thereon to
such Cut-Off Date.

      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.

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.

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 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


                                      -2-
<PAGE>

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 February 1, 2003 (the "Pooling and Servicing
Agreement"), among the Purchaser, as depositor, ABN AMRO Mortgage Group, Inc.,
as 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.

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.

      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 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


                                      -8-
<PAGE>

      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.

of the following conditions:

      A. The obligations of the Purchaser required to be performed by it on or
prior to the Closing Date pursuant to the terms of this Agreement shall have
been duly performed and complied with and all of the representations and
warranties of the Purchaser under this Agreement shall be true and correct as of
the date hereof and as of the Closing Date, and no event shall have occurred
which, with notice or the passage of time, or both, would constitute a default
under this Agreement, and the Seller shall have received a certificate to that
effect signed by an Authorized Officer of the Purchaser;

      B. The Seller shall have received, or the Seller's attorney shall have
received in escrow, a certificate signed by an Authorized Officer of the

12. Indemnification.

      A The Seller agrees to indemnify and hold harmless the Purchaser against
any and all losses, claims, expenses, damages or liabilities to which Purchaser
may become subject, insofar as such losses, claims, expenses, damages or
liabilities (or actions in respect thereof) arise out of or are 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.

      B The Purchaser agrees to indemnify and hold harmless the Seller solely in
its capacity as seller of the Mortgage Loans against any and all losses, claims,
expenses, damages or liabilities to which the Seller may become subject, insofar
as such losses, claims, expenses, damages or liabilities (or actions in respect
thereof) arise out of or are based upon any representation or warranty made by
the Purchaser in


                                      -11-
<PAGE>

Section 9 hereof on which the Seller has relied, being, or alleged to be,
materially untrue or incorrect (notwithstanding the Purchaser's lack of
knowledge with respect to the substance of any representation or warranty to
which Section 9 applies which is made to the best of the Purchaser's knowledge).
This indemnity will be in addition to any liability which the Purchaser may
otherwise have.

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

13. Notices. All demands, notices and communications hereunder shall be in

the parties hereto, or (b) by the Purchaser if the conditions to the Purchaser's
obligations to closing set forth under Section 10 hereof are not fulfilled as
and when required to be fulfilled or (c) by the Seller if the Purchaser's
obligations under Section 11 hereof are not fulfilled as and when required. In

will pay the out-of-pocket fees and expenses of the Purchaser in connection with
the transactions contemplated by this Agreement and in the event of a
termination pursuant to Section 14(c), the Purchaser agrees that it will pay the
out-of-pocket fees and expenses of the Seller in connection with the

invalid under applicable law, the Agreement shall be ineffective only to such
extent, without invalidating the remainder of this Agreement.

the terms of this Agreement.

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

      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 February 27, 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 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
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.
