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.

Although each servicing criterion required by Item 1122(d) of Regulation AB is
addressed in one or more of the Assessments of Compliance with Servicing
Criteria and related Attestation Reports included with this report, the
Servicer's, PHH Mortgage Corporation, Assessment of Compliance
and related Attestation Report did not address each of the servicing criteria
that the Servicer was required to address under the terms of the related
Servicing Agreement. The Servicer has not identified such failure to
provide an Assessment and Attestation for these items as a material failure to
fulfill its obligations under the related servicing agreement in the Servicer
Compliance Statement provided under Item 1123 of Regulation AB, because the
Servicer asserts that those items are not applicable to the Servicer.



Item 1123 of Regulation AB, Servicer Compliance Statement.

The servicer compliance statements are attached hereto under Item 15.
