                               APPENDIX   B*




1.  The Asserting Party 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, the Asserting Party 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.

2.  As to the issue identified at Section 229.1122(d)(1)(iv), SunTrust
    Mortgage 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 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 is working to formalize this
    agreement.  Regarding the issue identified at Section 229.
    1122(d)(2)(vii), SunTrust Mortgage has enhanced its procedures and
    controls around the relevant reconciliation process to prevent any future
    compliance concerns.
