This agreed-upon procedures engagement was conducted in accordance with attestation standards established by the American Institute of Certified Public Accountants. The sufficiency of these procedures is solely the responsibility of the Specified Parties. Consequently, we make no representation regarding the sufficiency of the procedures described below either for the purpose for which this report has been requested or for any other purpose.

The Loan Sellers are responsible for the information contained in the Data File.

We were instructed by the Loan Sellers to perform the agreed-upon procedures on all Mortgage Loans and all related Mortgaged Properties in the Data File.

A. We compared the Compared Attributes in the Data File to the corresponding information set forth in the Loan File (subject to the Instructions). Where more than one document was indicated, we used the highest priority document that we could locate in the Loan File. The document priority is the order provided by the Loan Sellers, which is summarized on Attachment A, with the highest priority document listed first.

We found such information in the Data File to be in agreement.

B. Using (i) certain information in the Data File and (ii) the Calculation Methodology, we recomputed the Recomputed Attributes in the Data File and compared the results of our recomputations to the corresponding information contained in the Data File.

We found such information in the Data File to be in agreement.

There were no conclusions that resulted from the procedures.

We were not engaged to, and did not, conduct an audit, examination, or review, the objective of which would be the expression of an opinion or conclusion on the Data File. Accordingly, we do not express such an opinion or conclusion. Had we performed additional procedures, other matters might have come to our attention that would have been reported to you.

The procedures performed were applied based on the methodologies, instructions, assumptions, and information provided to us by the Loan Sellers, without verification or evaluation of such methodologies, instructions, assumptions, and information by us; therefore, we express no opinion or any other form of assurance regarding (i) the reasonableness of the methodologies, instructions, assumptions, or information provided to us by the Loan Sellers, (ii) the physical existence of the Mortgage Loans and Mortgaged Properties, (iii) the reliability or accuracy of the documents furnished to us by the Loan Sellers which were used in our procedures, (iv) the adequacy of the disclosures in the Data File, or as to whether any of the statements expressed therein omit any material facts, or (v) matters of legal interpretation.

The procedures performed were not intended to address, nor did they address: (i) the conformity of the origination of the Mortgage Loans to stated underwriting or credit extension guidelines, standards, criteria

2

or other requirements, (ii) the value of collateral securing the Mortgage Loans being securitized, (iii) the compliance of the originators of the Mortgage Loans with federal, state, and local laws and regulations, or (iv) any other factor or characteristic of the Mortgage Loans that would be material to the likelihood that the issuer of the asset-backed security will pay interest and principal in accordance with applicable terms and conditions. The procedures performed were not intended to satisfy any criteria for due diligence published by a nationally recognized statistical rating organization (“NRSRO”).

The terms of our engagement are such that we have no obligation to update this report because of events and transactions that may subsequently occur.

This report is intended solely for the information and use of the Specified Parties. It is not intended to be and should not be used by any other person or entity, including investors and NRSROs, who are not identified in the report as Specified Parties but who may have access to this report as required by law or regulation.
