WHOLE LOAN PURCHASE AGREEMENT

Whole Loan Purchase Agreement (the "Agreement"), dated as of March 1,
2003 between ABN AMRO Mortgage Group, Inc. (the "Seller") and Washington Mutual
Mortgage Securities Corp. (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 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 March l, 2003 (the "Cut-Off Date") of
approximately $396,056,655 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
March 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.

SECTION 2. Mortgage Loan Schedule.

Attached to this Agreement as Schedule 1 is a listing of the Mortgage
Loans evidenced, in each case, by a promissory note, mortgage note or other
evidence of indebtedness (the "Mortgage Note") evidencing the indebtedness of
one or more obligors (the "Mortgagor') and the related mortgage, deed of trust
or other instrument securing a Mortgage Loan (the "Mortgage") 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.

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 101.35%
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.

(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 by the Seller 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 "Mortgagee 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 (including 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 (including 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 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,
dated as of March 1, 2003, among U.S. Bank National Association, as Trustee
(the, "Trustee"), Washington Mutual Mortgage Securities Corp. as Seller and
Servicer (in such capacity, the "Seller" or the "Servicer") and ABN AMRO
Mortgage Corporation as Depositor (the "Depositor")) 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) 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 location of its chief executive office or principal place of business;
and (C) any merger or consolidation or other change in Seller's identity or
material change in its corporate structure.

default, breach, violation or event of acceleration existing
under the Mortgage or the related Mortgage Note and, 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;

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

15) that based upon a representation by each
Mortgagor at the time of origination or assumption of the
applicable Mortgage Loan, approximately 97.00% of the Mortgage
Loans measured by principal balance were to be secured by
owner-occupied residences and approximately 3.00% of the
Mortgage Loans measured by principal balance were secured by
owner-occupied second home residences;

16) that an appraisal of each Mortgaged Property was

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;

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

18) 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;

19) each Mortgage Loan was either (A) originated

loan association, savings bank, commercial bank, credit union,
insurance company, or similar institution which is supervised

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;

20) 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;

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

22) 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 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;

23) 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;

24) 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;

25) 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;

26) 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;

27) 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 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;

28) 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;

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

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

31) 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.
With respect to representations and warranties contained in Section 8 which are
made to the Seller's knowledge other than the knowledge qualified portions of
Section 8(viii)(5) and Section 8(viii)(13), if it is discovered by either the
Seller or the Purchaser that the substance of such representation and warranty
is inaccurate and such inaccuracy materially and adversely affects the value of
the Mortgage Loan or the Purchaser's interest therein, the Purchaser shall be
entitled to all the remedies to which it would be entitled for a breach of
representation or warranty, including without limitation, the repurchase
requirements contained herein, notwithstanding the Seller's lack of knowledge
with respect to the inaccuracy at the time the representation or warranty was
made. 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 a 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, provided
that, if such Mortgage Loan was conveyed to a pass-through entity for which an
election was made under the real estate mortgage investment conduit ("REMIC")
regulations under the Internal Revenue Code, the Seller shall provide the
Purchaser with an opinion of counsel, reasonably satisfactory to the Purchaser,
that the substitution of the Qualifying Substitute Mortgage Loan (as defined
below) will not affect the status of the pass-through entity as a REMIC. 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"). 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.

(a) 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:

(i) The Purchaser is a corporation duly formed, validly
existing and in good standing under the laws of the State of Delaware;

(ii) 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 the Purchaser's corporate charter or by-laws
or will not conflict with or result in a breach of any of the terms or
provisions of, or constitute a default under, any indenture, mortgage,
deed of trust, loan agreement or other material agreement or instrument
to which the Purchaser is a party or by which the Purchaser or to which
any property or assets of the Purchaser is subject;

(iii) The Purchaser has all requisite corporate power,
authority and capacity to enter into this Agreement and to perform the
obligations required of it hereunder. This Agreement, assuming due
authorization, execution and delivery by the Seller, constitutes a
valid and legally binding obligation of the Purchaser, enforceable
against the Purchaser in accordance with its terms, subject, as to
enforcement, to bankruptcy, insolvency,

reorganization and other similar laws of general applicability relating
to or affecting creditors' rights and to general equity principles,
regardless of whether such enforcement is considered in a proceeding in

connection with the origination of any Mortgage Loan and which insures the

the Seller with respect to a Mortgage Loan shall be forwarded by the Seller to
the Purchaser or its designee by regular mail within five (5) business days of
the Seller's receipt thereof.

mortgage loans in its portfolio if the Mortgage Loans are not
specifically targeted;

(ii) promoting terms available for refinancing by sending
letters or promotional material to the mortgagors of all the mortgage
loans that it owns or services;

(iii) promoting terms available for refinancing by sending
letters or promotional material to the mortgagors of all the mortgage
loans of a specific type (e.g., conventional fixed-rate or conventional
adjustable-rate) that it owns or services;

(iv) promoting terms available for refinancing by sending
letters or promotional material to the mortgagors of all the mortgage
loans that fall within specific interest rate ranges that it owns or
services;

(v) promoting terms available for refinancing by communicating
with mortgagors of mortgage loans in its portfolio that one or more
predictive models indicate a propensity to prepay;

(vi) providing payoff information or otherwise cooperating
with individual Mortgagors who contact it about prepaying any Mortgage
Loan; or

(vii) advising individual Mortgagors who contact it about
prepaying any Mortgage Loan of refinancing terms or streamlined
origination arrangements that are available.

In no event, however, shall the Seller or any affiliate treat mortgage
loans that it holds in its own portfolio and the Mortgage Loans as separate
classes of mortgages for purposes of advertising the availability of refinancing
terms.

All demands, notices and communications hereunder shall be in writing

hypothecated by any party hereto without the written consent of the other party
to this Agreement. Notwithstanding anything to the contrary in this Section 22,
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 General Counsel 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 Whole Loan Purchase
Agreement, dated as of March 1, 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 xxxxx or by which it is bound,
or constitute a default or result in an acceleration under any of the foregoing,
or result in the violation of any law, rule, regulation, order, judgment or
decree to which Seller or its property is subject, which, in any of the above
cases, would materially and adversely affect Seller's ability to perform its
obligations under the Purchase Agreement.

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