Item 1122 of Regulation AB, Compliance with Applicable Servicing Criteria. The reports on assessment of compliance with the servicing criteria for asset-backed securities and the related attestation reports on such assessments of compliance are attached hereto under Item 15. 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. SunTrust Mortgage, Inc. has assessed its compliance with Applicable Servicing Criteria for the Reporting period and has identified two instances of noncompliance with the servicing criteria as set out in Section 229.1122(d)(1)(iv) and Section 229.1122(d)(2)(vii), respectively. In regards to the former, SunTrust Mortgage, Inc. did not strictly maintain the required fidelity bond coverage amount at all times during 2007. And, in regards to the latter, certain bank reconciliations contained items that required enhanced explanations and that were not fully resolved within 90 calendar days of original identification. As to the issue identified at Section 229.1122(d)(1)(iv), SunTrust Mortgage, Inc. maintained fidelity bond coverage in the amount of $150MM throughout calendar year 2007, which was determined to be insufficient according to applicable FNMA transaction agreement terms. This deficiency was an issue for limited portions of the year and resulted from an increase in the volume of the servicing portfolio. SunTrust Mortgage, Inc. has requested a waiver from FNMA stating this coverage amount is adequate without regard for the size of the residential servicing portfolio, subject to an annual FNMA review. FNMA has verbally agreed to this request, and SunTrust Mortgage, Inc. is working to formalize this agreement. Regarding the issue identified at Section 229.1122(d)(2)(vii), SunTrust Mortgage, Inc. has enhanced its procedures and controls around the relevant reconciliation process to prevent any future compliance concerns.
