Report on Assessment of Compliance with Servicing Criteria

LaSalle Bank National Association (LaSalle) is responsible for assessing compliance with the servicing criteria applicable to it under paragraph (d) of
Item 1122 of Regulation AB (17 C.F.R., 229.1122(d)), as of and for the 12-month period ending December 31, 2007 (the Reporting Period), as set forth in Appendix A hereto. The transactions covered by this report include
mortgage-backed securities transactions for which LaSalle, as trustee, paying agent, or custodian, performed servicing activities, which transactions were initially closed on or after January 1, 2006, and that were registered with the
Securities and Exchange Commission pursuant to the Securities Act of 1933 (the Platform). LaSalle used the criteria set forth in paragraph (d) of Item 1122 of Regulation AB to assess its compliance with the applicable servicing
criteria for the Reporting Period with respect to the Platform. The criteria listed in the column titled Servicing Criteria Inapplicable to LaSalle Bank National Association (as trustee, paying agent, or custodian) on Appendix A hereto
are inapplicable to LaSalle based on the activities it performs in its role as trustee, paying agent, or custodian with respect to the Platform.

Except as
identified on Appendix B hereto, LaSalle has complied, in all material respects, with the applicable servicing criteria identified in Appendix A hereto for the Reporting Period with respect to the Platform taken as a whole.

PricewaterhouseCoopers LLP, an independent registered public accounting firm has issued an attestation report on LaSalles compliance with the applicable servicing
criteria for the Reporting Period.
