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(a).

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.  SunTrust Mortgage has enhanced its
procedures and controls around the relevant reconciliation process to
prevent future compliance concerns.

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.



Item 1123 of Regulation AB, Servicer Compliance Statement.

The servicer compliance statements are attached hereto under Item 15(a).
