Whole Loan Purchase Agreement (the "Agreement"), dated as of December 23,
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 December l, 2003 (the "Cut-Off Date") of approximately
$354,678,057 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
December 23, 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 (the "Mortgagor") and the related mortgages, deeds of trust or other
instruments 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 * % 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 "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 (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

rights) and the related Mortgage Note, the Mortgage and the contents of the

of the documents pertaining to each Mortgage Loan.

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

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

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 93.95% of the Mortgage Loans measured by principal
balance were to be secured by owner-occupied residences and
approximately 6.05% of the Mortgage Loans measured by principal
balance were secured by owner-occupied second home residences;

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 directly by
or closed in the name of either: (i) a savings and loan association,
savings bank, commercial bank, credit union, insurance company, 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;

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 included in the
appraised value thereof, 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) as of the Closing Date, each 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;

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;

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

33) no Loan is a "high-cost home loan" as defined in the
Georgia Fair Lending Act, as amended, or in the New York Predatory
Lending Law, codified as N.Y. Banking Law Section 6-l, N.Y. Gen.
Bus. Law Section 771-a, and N.Y. Real Prop. Acts Law Section 1302,
the Arkansas Home Loan Protection Act, as amended, the Kentucky
Revised Statutes Section 360.100, as amended, or the Florida Home
Loan Protection Act ss.494.007 (the "Florida Act"); no Loan is a
"covered loan" as defined in the District of Columbia Home Loan
Protection Act ss.26-1151.01 (the "D.C. Act"); no Loan is a
"high-rate, high-fee mortgage" as defined in Maine Consumer Credit
Code -- Truth In Lending ss.8-103 (the "Maine Act"); and no Loan is
a "home loan" as defined in Nevada Revised Statutes title 52, as
amended by Assembly Xxxx No. 284, 72nd Session (Nevada 2003) (the
"Nevada Act"); and

34) none of the Mortgage Loans are subject to the Home
Ownership and Equity Protection Act of 1994 or any comparable state
law.

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 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"). If the breach of representation and warranty that gave rise to the
obligation to repurchase or substitute a Loan pursuant to this Section 8 was the
representation set forth in clause (viii)(6) of this Section 8, then the Seller
shall pay to the Trust Fund, concurrently with and in addition to the remedies
provided in the preceding sentence, an amount equal to any liability, penalty or
reasonable expense that was actually incurred and paid out of or on behalf of
the Trust Fund, and that directly resulted from such breach, or if incurred and
paid by the Trust Fund thereafter, concurrently with such payment. 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.

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

mortgagee policy of title insurance which is issued in connection with the
origination of any Mortgage Loan and which insures the Purchaser subsequent to

shall accumulate such payments and forward them to the Purchaser every second
business day via overnight mail. After the first day of the third month
following the month in which the Transfer Date occurs, any payment received by
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.

affiliate from:

(i) advertising its availability for handling refinancings of
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;

or promotional material to the mortgagors of all the mortgage loans of a

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.

SECTION 15. Notices.

All demands, notices and communications hereunder shall be in writing and
shall be deemed to have been duly given if mailed, by registered or certified

and shall survive transfer and sale of the Mortgage Loans to the Purchaser.

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

which shall be an original, but both of which together shall constitute one and
the same agreement.

enforceable by the Seller and the Purchaser and their permitted successors and

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 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 Washington
Mutual Mortgage Securities Corp. (the "Purchaser") pursuant to a Whole Loan
Purchase Agreement, dated as of December 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
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,
