Compliance with Applicable Servicing Criteria Item 1123 of Regulation AB. American Home Mortgage: Originator
On August 6, 2007, American Home Mortgage Holdings, Inc. and seven affiliates, including American Home Mortgage
Corp., which is an originator of certain of the mortgage loans, each filed voluntary petitions for relief under Chapter 11
of Title 11 of the United States Code in the United States Bankruptcy Court for the District of Delaware (the "Bankruptcy
Court"). Judge Christopher S. Sontchi is presiding over the Debtors' Chapter 11 bankruptcy cases, which are being
jointly administered under Case Number 07-11047. At this time, certain of the Debtors, including American Home
Mortgage Corp., are operating their businesses as "debtors-in-possession" under the jurisdiction of the Bankruptcy
Court. None. None. None. Item 1115(b) of Regulation AB. Information required by Item 1119 has been omitted from this annual report on Form 10-K because it is materially the
same information as has been provided previously in a prospectus timely filed pursuant to Rule 424 promulgated under
the Securities Act of 1933 under the same Central Index Key (CIK) code as this annual report on Form 10-k. LaSalle Bank National Association:
LaSalle Bank National Association's ("LaSalle") Report on Assessment of Compliance with Servicing Criteria for 2007 (the
"2007 Assessment") attached to this Report on Form 10-K describes in Appendix B the following material instance of
noncompliance related to investor reporting: "1122(d)(3)(i)(A) and (B) - During the Reporting Period, certain monthly investor or remittance reports were not
prepared in accordance with the terms set forth in the transaction agreements and certain investor reports did not
provide the information calculated in accordance with the terms specified in the transaction agreements for which certain
individual errors may or may not have been material." The investor reporting errors identified on LaSalle's 2007 Assessment as material instances of noncompliance (the
"Investor Reporting Errors") included, for example, revised delinquency, REO, foreclosure, repurchase, payoff or
modified loan counts, category indicators and/or balances. The conclusion that the Investor Reporting Errors amounted
to a material instance of noncompliance was based primarily on the aggregate number of errors as opposed to the
materiality of any one error. The Investor Reporting Errors were generally caused by human error resulting primarily from high volume monthly data
processing demands that had to be addressed within constricted time frames with less than a full complement of
operational staff. Between the fourth quarter of the Reporting Period and the date of the 2007 Assessment, LaSalle
has employed additional operational staff to accommodate the high volume of monthly investor reporting requirements
and minimize the risk of the Investor Reporting Errors recurring. Other necessary controls are in place to minimize the
risk of such errors. With respect to the specific pool assets and asset-backed securities related to the Investor Reporting Errors, the errors
did not have, and are not reasonable likely in the future to have, any material impact or effect on pool asset
performance, servicing of the pool assets and payments or expected payments on the mortgage-backed securities.
In this transaction, LaSalle served as custodian. Please note that this additional disclosure does not relate to LaSalle's
custodial Servicing Criteria under Item 1122. Item 1114(b)(2) of Regulation AB. Credit Enhancement and Other Support, Except for Certain
