**Material Instances of Noncompliance by LaSalle**

** **

1122(d)(3)(i)(A) and (B) – During the Reporting Period, certain monthly investor or remittance reports were not preparedin 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 havebeen 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 asopposed 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 afull 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 andminimize 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 impactor effect on pool asset performance, servicing of the pool assets and payments or expected payments on the mortgage-backed securities.
