             Report on Assessment of Compliance with Servicing Criteria



Bank of America,  National  Association  ("Bank of  America"),  as  successor by
merger to LaSalle  Bank  National  Association,  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,  2008 (the  "Reporting  Period"),  as set forth in
Appendix A hereto. The transactions  covered by this report include asset-backed
securities,  primarily mortgage-backed securities, for which Bank of America, 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,  as  well  as  transactions  that  were  exempt  from
registration  but  required  an  assessment  of  compliance  with the  servicing
criteria  applicable  to it under  Regulation  AB as  prescribed  in  applicable
transaction  agreements (the "Platform").  Bank of America 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 Bank of America, National Association (as trustee, paying agent,
or custodian)" on Appendix A hereto are inapplicable to Bank of America based on
the activities it performs with respect to the Platform.

Except as identified on Appendix B hereto, Bank of America 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 Bank of America's compliance with the applicable
servicing criteria for the Reporting Period.

             Report of Independent Registered Public Accounting Firm


To the Board of Directors of Bank of America, National Association:

We have examined Bank of America,  National  Association's  (the "Company"),  as
successor by merger to LaSalle Bank National  Association,  compliance  with the
servicing  criteria  set forth in Item  1122(d) of the  Securities  and Exchange
Commission's   Regulation  AB  for  the  asset  backed   securities,   primarily
mortgage-backed  securities for which the Company, 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,  as well as
transactions  that were exempt from  registration  but required an assessment of
compliance with the servicing  criteria  applicable to it under Regulation AB as
prescribed in applicable  transaction  agreements (the "Platform")  described in
the accompanying Report on Assessment of Compliance with Servicing Criteria (the
"Compliance  Statement"),  as of December  31, 2008 and for the year then ended,
excluding criteria  1122(d)(1)(iii) and  1122(d)(4)(iv)-(xiv)  which the Company
has determined are not  applicable to the servicing  activities  performed by it
with  respect to the  Platform.  Management  is  responsible  for the  Company's
compliance  with the servicing  criteria.  Our  responsibility  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's  compliance  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 of
selected 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 the selected  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 may have  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 on the 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  December  31,  2008.  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
specified in the transaction agreements.

In our opinion, except for the material noncompliance described in the preceding
paragraph,   Bank  of   America,   National   Association   complied   with  the
aforementioned  applicable  servicing  criteria  as of and  for the  year  ended
December 31, 2008 for the Platform, in all material respects.
