Management is responsible for MidFirst’s compliance with the servicing criteria. Our responsibility is to express an opinion on management’s assertion about MidFirst’s compliance with the relevant servicing criteria 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 MidFirst’s compliance with the servicing criteria and performing such other procedures as we considered necessary in the circumstances. Our examination included a selection of samples of compliance activities related to the platform during the examination period and determining whether MidFirst performed those activities in compliance with the relevant servicing criteria. Our testing of compliance activities was limited to activities performed by MidFirst during the period covered by this report. Our procedures did not include determining whether errors may have occurred prior to our tests that may have affected the balances or amounts calculated or reported by MidFirst during the period covered by this report forthe selected transactions or any other transaction. We believe that our examination provides a reasonable basis for our opinion. Our examination does not provide a legal determination on MidFirst’s compliance with the servicing criteria.

 

In our opinion, management’s assertion that MidFirst, complied with the servicing criteria related to the aforementioned Mortgage Pass-Through Certificate Security Transactions, backed by the mortgage collateral pledged under such Mortgage Pass-Through Certificate Security Transactions, as of December 31, 2007, and from September 1, 2007, through December 31, 2007, is fairly stated, in all material respects.
