Management is responsible for the Company's compliance with the servicing criteria.  Ourresponsibility is to express an opinion on the Company's compliance with the 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 the Company'scompliance 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 ofselected servicing activities related to the Platform, and determining whether the Company processed those selected transactions and performed those selected activities in compliance with the applicable servicing criteria.  Our procedures were limited to theselected 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 mayhave 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 onthe Company's compliance with the servicing criteria.

Our examination disclosed the following material noncompliance with the servicing criteria set forth in Item 1122(d)(3)(i)(A) and (B) of Regulation AB applicable to the Company during the year ended December31, 2007.  Certain reports to investors did not include certain required information in accordance with terms set forth in the transaction agreements and certain reports to investors did not provide information calculated in accordance with the terms specifiedin the transaction agreements.

 

In our opinion, except for the material noncompliance described in the preceding paragraph, LaSalle Bank National Association complied with the aforementioned applicable servicing criteria as of and for theyear ended December 31, 2007 for the Platform, in all material respects.
