           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.
