        THIS LOAN PURCHASE AGREEMENT, dated February 12, 2003, is entered into
by and among DLJ Mortgage Capital, Inc., a Delaware corporation (“Seller”),
Credit Suisse First Boston Mortgage Acceptance Corp., a Delaware corporation
(“Purchaser”), U.S. Bank National Association, as indenture trustee (the
“Indenture Trustee”) and Irwin Whole Loan Home Equity Trust 2003-A (the
“Issuer”):

WITNESSETH:

        WHEREAS, Seller, in the ordinary course of its business acquires and
originates mortgage loans and acquired or originated all of the mortgage loans
listed on the Loan Schedule attached as Exhibit A hereto (the “Loans”);

        WHEREAS, the parties hereto desire that: (i) the Seller sell the Loans
to the Purchaser on the Closing Date pursuant to the terms of this Loan Purchase
Agreement together with the Basic Documents, and (ii) the Seller make certain
representations and warranties on the Closing Date;

        WHEREAS, pursuant to the Trust Agreement, the Purchaser will sell the
Loans and transfer all of its rights under this Loan Purchase Agreement to the
Issuer on the Closing Date;

        NOW, THEREFORE, for and in consideration of the sale of the Loans from
Seller to the Purchaser on the date hereof, the Purchaser shall pay to Seller on
the date hereof by wire transfer of immediately available funds the net proceeds
to the Purchaser of the sale of the Notes, less the amount deposited into the
Basis Risk Reserve Fund pursuant to the Indenture, together with the
Certificates, the parties hereto hereby agree as follows:

         Section 1. Transfer of Loans. (a) Seller hereby sells, transfers,
assigns and otherwise conveys to Purchaser (A) the Loans, including the Mortgage
Notes, the Mortgages, any related insurance policies and all other documents in
the related Loan Files and including any Eligible Substitute Loans; (B) pool
insurance policies, hazard insurance policies, and bankruptcy bonds relating to
the foregoing, and (C) all amounts payable after the Cut-off Date to the holders
of the Loans in accordance with the terms thereof. In addition, Seller has
delivered to the Purchaser or the Custodian, as directed by the Purchaser, the
Loan Schedule and the documents listed on Exhibit C.

         (b)   Based on the Initial Certification of the Custodian, the
Indenture Trustee acknowledges receipt by the Custodian of the documents
identified in the Initial Certification and declares that the Custodian holds
such documents and the other documents delivered to the Custodian constituting
the applicable Loan Files, in trust for the exclusive use and benefit of all
present and future Noteholders. The Indenture Trustee acknowledges that it or
the Custodian will maintain possession of the Loans and the Loan Files in the
State of Illinois, as directed by the Purchaser, unless otherwise permitted by
the Rating Agencies.

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

         (c)   The Indenture Trustee agrees to deliver on the Closing Date to
the Purchaser and the Servicer an Initial Certification from the Custodian (to
the extent received by the Indenture Trustee from the Custodian). Based on its
review and examination, and only as to the documents identified in such Initial
Certification, the Custodian, pursuant to the terms of the Custodial Agreement,
will acknowledge that such documents appear regular on their face and relate to
such Loan. Neither the Indenture Trustee nor the Custodian shall be under any
duty or obligation to inspect, review or examine said documents, instruments,
certificates or other papers to determine that the same are genuine,
enforceable, recordable or appropriate for the represented purpose or that they
have actually been recorded in the real estate records or that they are other
than what they purport to be on their face; provided, however, that neither the
Indenture Trustee nor the Custodian shall make any determination as to whether
(i) any endorsement is sufficient to transfer all right, title and interest of
the party so endorsing, as noteholder or assignee thereof, in and to that
Mortgage Note or (ii) any assignment is in recordable form or is sufficient to
effect the assignment of and transfer to the assignee thereof under the mortgage
to which the assignment relates. Not later than 90 days after the Closing Date,
upon receipt of a Final Certification from the Custodian provided for in the
Custodial Agreement, the Indenture Trustee shall deliver to the Purchaser, the
Seller and the Servicer such Final Certification, with any applicable exceptions
noted thereon.

         (d)   If, in the course of such review, the Indenture Trustee is
notified by the Custodian that any document constituting a part of a Loan File
does not meet the requirements of Exhibit C hereto, the Indenture Trustee shall
cause the Custodian to list such as an exception in the Final Certification.

         (e)   The Seller shall promptly correct or cure such defect within 90
days from the date it is so notified of such defect and, if the Seller does not
correct or cure such defect within such period, the Seller shall either (i)
substitute for the related Loan an Eligible Substitute Loan, which substitution
shall be accomplished in the manner and subject to the conditions set forth in
Section 2(d), or (ii) purchase such Loan within 90 days from the date the Seller
was notified of such defect in writing at the Repurchase Price of such Loan if
such defect materially and adversely affects the value of the related Loan or
interests of the Noteholders or the Certificateholders; provided, however, that
if the cure, substitution or repurchase of a Loan pursuant to this provision is
required by reason of a delay in delivery of any documents by the appropriate
recording office, then the Seller shall be given 270 days from the Closing Date
to cure such defect or substitute for, or repurchase such Loan; and further
provided, that the Seller shall have no liability for recording any Assignment
of Mortgage in favor of the Indenture Trustee or for the Servicer's failure to
record such Assignment of Mortgage, and the Seller shall not be obligated to
repurchase or cure any Loan as to which such Assignment of Mortgage is not
recorded. The Indenture Trustee shall deliver written notice to each Rating
Agency within 270 days from the Closing Date indicating each Mortgage (a) which
has not been returned by the appropriate recording office or (b) as to which
there is a dispute as to location or status of such Mortgage. Such notice shall
be delivered every 90 days thereafter until the related Mortgage is returned to
the Custodian. Any substitution shall not be effected prior to the additional
delivery to the Indenture Trustee or the Custodian, of a Request for Release and
the Loan File for any such Eligible Substitute Loan. The Repurchase Price for
any such Loan shall be deposited by the Seller in the Payment Account on or
prior to the Business Day immediately preceding such Payment Date in the month
following the month of repurchase and, upon receipt of such deposit,

2

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

the Custodian, pursuant to the terms of the Custodial Agreement, will release
the related Loan File to the Seller and will execute and deliver at the Seller's
request such instruments of transfer or assignment prepared by the Seller, in
each case without recourse, representation and warranty or as shall be necessary
to vest in the Seller's, or a its designee, the interest of the Purchaser, the
Issuer, and the Indenture Trustee in any Loan released pursuant hereto. It is
understood and agreed that the obligation of the Seller to cure, substitute for
or to repurchase any Loan which does not meet the requirements of this Section
shall constitute the sole remedy respecting such defect available to the
Indenture Trustee, the Purchaser and any Certificateholder against the Seller.

         (f)   All of the Loan Files are being held pursuant to the Custodial
Agreement. Notwithstanding anything to the contrary contained herein, the
parties hereto acknowledge that the functions of the Indenture Trustee with
respect to the custody, acceptance, inspection and release of the Loan Files
pursuant to Sections 1 and 2 hereof shall be performed by the Custodian. In
connection with the assignment of any Loan registered on the MERS(R)System, the
Indenture Trustee shall cause, at the Servicer's expense, as soon as practicable
after the Closing Date, the MERS(R)System to indicate that such Loans have been
assigned by the Seller to the Indenture Trustee in accordance with this Loan
Purchase Agreement, the Owner Trust Agreement and the Indenture for the benefit
of the Noteholders by including (or deleting, in the case of Loans which are
repurchased in accordance with this Agreement) in such computer files (a) the
code "[IDENTIFY INDENTURE TRUSTEE SPECIFIC CODE]" in the field "[IDENTIFY THE
FIELD NAME FOR INDENTURE TRUSTEE]" which identifies the Indenture Trustee and
(b) the code "[IDENTIFY SERIES SPECIFIC CODE NUMBER]" in the field "Pool Field"
which identifies the series of the Notes issued in connection with such Loans.
Indenture Trustee agrees that it will not alter the codes referenced in this
paragraph with respect to any Loan during the term of this Loan Purchase
Agreement unless and until such Loan is repurchased in accordance with the terms
of this Loan Purchase Agreement.

contemplated hereby;

without recourse, representation or warranty as shall be necessary to vest in

Loan shall not be an asset of the Issuer.

        It is understood and agreed that the obligation of Seller to cure any
breach, or to repurchase or substitute for, any Loan as to which such a breach
has occurred and is continuing shall constitute the sole remedy respecting such
breach available to Purchaser, the Servicer, the Issuer, the Certificateholders
(or the Owner Trustee on behalf of the Certificateholders) and the Noteholders
(or the Indenture Trustee on behalf of the Noteholders) against Seller.

the parties hereto that the conveyance by the Seller to the Purchaser pursuant
to this Loan Purchase Agreement of the Loans be, and be construed as, an
absolute sale and assignment by the Seller to the Purchaser. Further, it is not
intended that the conveyance be deemed to be the grant of a security interest in
the Loans by the Seller to the Purchaser to secure a debt or other obligation.
However, in the event that the Loans are held to be property of the Seller, or
if for any reason this Loan Purchase Agreement is held or deemed to create a
security interest in the Loans, then (i) this Loan Purchase Agreement shall be a

Any security agreement, chattel mortgage or equivalent document related to and
delivered in connection with the Loan establishes and creates a valid,
subsisting, enforceable and perfected second lien and second priority security
interest on the property described therein and Seller has full right to sell and
assign the same to Purchaser, provided, however, that any representation as to
the enforceability of any security interest or lien is subject to bankruptcy,
insolvency, reorganization, moratorium or other similar laws affecting the
rights of creditors generally and general principles of equity (whether
considered in a proceeding at law or equity).;

                  (g)     Mechanics' Liens.   To the best of Seller's knowledge
there are no mechanics' or similar liens or claims which have been filed for
work, labor or material (and no rights are outstanding that under law could give
rise to such liens) affecting the related collateral which are or may be liens
prior to or equal to the lien of the related Loan;

                  (h)     Unpaid Taxes.   To the best of Seller's knowledge all
taxes, governmental assessments, insurance premiums, water, sewer and municipal
charges, leasehold payments or ground rents which previously became due and
owing have been paid, or escrow funds have been established in an amount
sufficient to pay for every such escrowed item which remains unpaid and which
has been assessed but is not yet due and payable;

                  (i)     No Defenses.   The Loan is not subject to any right of
rescission, set-off, counterclaim or defense, including, without limitation, the
defense of usury, nor will the operation of any of the terms of the Loan, or the
exercise of any right thereunder, render the Loan unenforceable, in whole or in
part, or subject to any right of rescission, set-off, counterclaim or defense,
including the defense of usury, and no such right of rescission, set-off,
counterclaim or defense has been asserted with respect thereto;

                  (j)     No Damage.  To the best of Seller's knowledge the
Mortgaged Property is not subject to any material damage by waste, fire,
earthquake, windstorm, flood or other casualty. At origination of the Loan there
was, and there currently is, no proceeding pending for the total or partial
condemnation of the Mortgaged Property;

                  (k)     Improvements.  To the best of Seller's knowledge all
improvements subject to any Mortgage which were considered in determining the
appraised value of the Mortgaged Property lie wholly within the boundaries and
building restriction lines of the

unit) and no improvements on adjoining properties encroach upon the related
Mortgaged Property except those which are insured against by a title insurance
policy and all improvements on the property comply with all applicable zoning
and subdivision laws and ordinances;

                  (l)     Recordation.  Seller has delivered or caused to be
delivered to the Purchaser or the Custodian on behalf of the Purchaser the
original Mortgage bearing evidence that such instruments have been recorded in
the appropriate jurisdiction where the Mortgaged Property is located as
determined by Seller (or, in lieu of the original of the Mortgage or the
assignment thereof, a duplicate or conformed copy of the Mortgage or the
instrument of assignment, if any, together with a certificate of receipt from
Seller or the settlement agent who handled the closing of the Loan, certifying
that such copy or copies represent true and correct copy(ies) of the originals)
and that such original(s) have been or are currently submitted to be recorded in
the appropriate governmental recording office of the jurisdiction where the
Mortgaged Property is located) or a certification or receipt of the recording
authority evidencing the same;

                  (m)     Delinquencies.   As of the Cut-off Date, (a) no more
than .51% of the Loans are more than 30 days delinquent; (b) none of the Loans
are more than 60 days delinquent; and (c) none of the Loans are 90 days or more
delinquent;

                  (n)     Original.   The Loan is original and genuine and is
the legal, valid and binding obligation of the maker thereof, enforceable in all
respects in accordance with its terms subject to bankruptcy, insolvency,
moratorium, reorganization and other laws of general application affecting the
rights of creditors and by general equitable principles;

                  (o)     Closed End.   The Loan has been closed and the
proceeds of the 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 the Loan and the recording of the Mortgage were paid, and the
Mortgagor is not entitled to any refund of any amounts paid or due under the
Mortgage Note or Mortgage; and

                  (p)     REMIC Ineligible.   As of the Cut-off Date, not less
than 57% of the Loans, by Cut-off Date Loan Balance, are REMIC Ineligible Loans.
