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).

Assurant, Inc. disclosed the following material noncompliance with the
servicing criteria set forth in Item 1122(d)(4)(xii) of Regulation AB
applicable to Assurant, Inc. during the year ended December 31, 2007. As
required by Item 1122(d)(4)(xii) of Regulation AB, any late payment penalties in
connection with any payment to be made on behalf of an obligor are paid from
the servicer's funds and are not charged to the obligor, unless the late payment
was due to the obligor's error or omission. Assurant, Inc. did not have, during
the Reporting Period, sufficient policies and procedures to capture the
information with respect to the Platform Transactions necessary to determine
compliance with 1122(d)(4)(xii).


Avelo Mortgage, L.L.C. assessed its compliance with the Applicable Servicing
Criteria for the year ended December 31, 2007 and has identified the
following instances of non-compliance with the servicing criterion set forth
in Items 1122(d)(2)(vii)(D) and 1122(d)(4)(x)(C) of Regulation AB with
respect to the Platform (as defined in Avelo Mortgage L.L.C.'s report).
Specifically, account reconciling items were not resolved within 90
calendar days of their original identification, or such other number of
days specified in the transaction agreements, as required by
Item 1122(d)(2)(vii)(D)and Avelo Mortgage, L.L.C. did not return to the
obligor funds held in trust for an obligor within 30 calendar days of full
repayment of the related pool asset, as required by Item 1122(d)(4)(x)(C).

Avelo Mortgage, L.L.C. acknowledges that for a period in 2007, bank accounts
were not reconciled in strict compliance with Reg. AB. To address this
issue, Avelo Mortgage, L.L.C. added additional staff to ensure timely
reconciliations and compliance with Reg AB. As of the date of the audit,
all bank account reconciliations were current. No issues were found or
arose from the delay in reconciling the bank accounts.

Avelo Mortgage, L.L.C. also acknowledges that for a period in 2007, escrow
funds were not returned to the obligor within 30 calendar days of full
repayment in compliance with Reg. AB due to a system issue. A system
enhancement erroneously affected the refund check process. Once the issue
was identified, the system was corrected.

As of the date of the audit, escrow fund refunds have been returned to the
obligor within 30 calendar days and no issues were found or arose from the
delay in returning the funds to the account holders.



Item 1123 of Regulation AB, Servicer Compliance Statement.

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