Report of Independent Registered Public Accounting Firm
We have examined management's assertion, included in the accompanying Management's Assertion on Compliance with Item 1122 Criteria, that LaSalle Bank National Association ("LBNA" or "the Company"), a wholly owned subsidiary of LaSalle Bank Corporation, complied with the servicing criteria set forth in Item 1122 (d) of the Securities and Exchange Commission's Regulation AB for individual residential mortgage-backed transactions subsequent to January 1, 2006 where LBNA has been appointed master servicer and where the pool assets for such transactions, master serviced by LBNA, reside on its SBO 2000 loan servicing system ("the Platform") as of and for the year ended December 31, 2006, except for those criteria which the Company has determined are not applicable to the activities performed by them with respect to the Platform covered by this report. See Appendix A of management's assertion for a list of servicing criteria determined by the Company to be applicable to the activities performed by them with respect to the Platform. Management is responsible for the Company's compliance with those servicing criteria. Our responsibility is to express an opinion on management's assertion about 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's compliance with the applicable servicing criteria and performing such other procedures as we considered necessary in the circumstances. Our examination included testing of less than all of the individual mortgage transactions that comprise the platform, testing of less than all of the 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 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 for the selected transactions or any other transactions. 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 servicing criteria as of and for the year ended December 31, 2006 for the Platform is fairly stated, in all material respects.
