Management is responsible for the Company's compliance with the servicing criteria. Our responsibility is to express an opinion on management's assertion based on our examination. Our examination was conducted in accordance with standards of the Public Company Accounting Oversight Board  (United States) and, accordingly, included examining, on a test basis, evidence about the Company's compliance with the applicable servicing criteria and performing such other procedures as we considered necessary in the circumstances. Our examination included testing of selected asset-backed transactions and securities that comprise the Platform, testing of selected servicing activities related to the Platform, and determining whether the Company processed those selected transactions and performed those s elected activities in compliance with the applicable servicing criteria. 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 detect noncompliance arising from errors that may have occurred prior to or subsequent to our tests that may have affected the balances or amounts calculated or reported by the Company during the period covered by this report. We believe that our examination provides a reasonable basis for our opinion. Our examination does not provide a legal determination on the Company's compliance with the servicing criteria. In our opinion, management's assertion that the Company complied with the aforementioned applicable servicing criteria as of and for the year ended December 31, 2007 for the asset-backed securities transactions backed by prime residential mortgages serviced on the Real Estate ("RE") servicing system where the related asset-backed securities were outstanding during the Reporting Period is fairly stated, in all material respects. /s/ PricewaterhouseCoopers LLP****February 25, 2008
