        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.
