Management is responsible for the Company’s compliance with those servicing criteria. Our responsibility is to express an opinion on the Company’s compliancebased on our examination.

Our examination was conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States) and, accordingly, included examining, on atest basis, evidence about the Company’s compliance with the servicing criteria specified above and performing such other procedures as we considered necessary in the circumstances. Our examination included testing selected asset-backed transactions andsecurities that comprise the Platform, testing selected servicing activities related to the Platform, and determining whether the Company processed those selected transactions and performed those selected activities in compliance with the servicing criteria. Furthermore, our procedures were limited to the selected transactions and servicing activities performed by the Company during the period covered by this report.  Our procedures were not designed to determine whether errors may have occurred either prior to orsubsequent to our tests that may have affected the balances or amounts calculated or reported by the Company during the period covered by this report for the selected transactions or any other transactions. We believe that our examination provides a reasonable basisfor our opinion.  Our examination does not provide a legal determination on the Company’s compliance with the servicing criteria.

Our examination disclosed the following material noncompliance with servicing criteria 1122(d)(2)(i) and 1122(d)(3)(ii) applicable to the Company as of and for the twelve monthsended December 31, 2007.  Related to servicing criterion 1122(d)(2)(i), in some instances, with respect to certain transactions for which the transaction documents require that funds be deposited into the custodial bank accountson the day funds are received by the Company, funds were not deposited to the custodial bank accounts in accordance with the terms of the transaction documents.  Related to servicing criterion 1122(d)(3)(ii), in some instances,amounts due to investors were not allocated and remitted in accordance with timeframes as specified in the transaction agreements.
