Item 1117 of Regulation AB, Legal Proceedings.

Legal Proceedings Regarding Countrywide Financial Corporation

Pursuant to a Form 10-K filed by Countrywide Financial Corporation ("the
Company") on February 29, 2008 (Commission File No. 001-8422; CIK No.
0000025191), the parent of Countrywide Home Loan Servicing LP, one of the
servicers and original loan sellers, the Company stated that various
lawsuits alleging claims for derivative relief on behalf of the Company and
securities, retirement plan, and other class action suits have recently been
brought against it and certain current and former officers, directors and
retirement plan administrators in either federal district court in Los Angeles,
California, or state superior court in Los Angeles, or state court in Delaware.
The Company stated that among other things, these lawsuits allege breach of
state law fiduciary duties and violation of the federal securities laws and the
Employee Retirement Income Security Act of 1974 ("ERISA").  The Company stated
that these cases allege, among other things, that the Company did not disclose
complete and accurate information about mortgage lending practices and financial
condition. The Company stated that shareholder derivative cases brought in
federal court are brought on the Company's behalf and do not seek recovery of
damages from the Company.

The Company stated that two consolidated cases alleging claims for derivative
relief on behalf of the Company are also pending in federal district court in
Delaware, and allege, among other things, that certain of the Company's proxy
filings contain incorrect statements relating to the compensation of the Chief
Executive Officer.

The Company stated that various class action lawsuits relating to the proposed
merger with Bank of America have been filed in the state courts of California
and Delaware on behalf of a proposed class of shareholders against the Company,
the Company's directors and Bank of America.  The Company stated that the class
action lawsuits filed in state court in California have been removed to federal
court in Los Angeles and that these lawsuits allege that the Company's directors
breached their fiduciary duties to the Company's shareholders by entering into
the merger agreement with Bank of America and that Bank of America allegedly
aided and abetted those alleged breaches.  The Company stated that, similarly,
the plaintiffs in the shareholder derivative lawsuits brought in California
state and federal court recently have amended their complaints to add similar
class action allegations relating to the proposed merger with Bank of America.

The Company stated that it is difficult to predict the resulting outcome of
these proceedings, particularly where investigations and proceedings are in
early stages.  The Company stated that given the inherent difficulty in
predicting the outcome of legal proceedings, the Company cannot estimate losses
or ranges of losses for legal proceedings where there is only a reasonable
possibility that a loss may be incurred, such as those discussed in the two
immediately preceding paragraphs.  The Company stated that it provides for
potential losses that may arise out of legal proceedings to the extent such
losses are deemed probable and can be estimated.  The Company stated that
although the ultimate outcome of the legal proceedings discussed above cannot be
ascertained at this time, the Company believes that any resulting liability will
not materially affect the consolidated financial position; such resolution,
however, could be material to operating results for a particular future period
depending upon the outcome of the proceedings and the operating results for a
particular period. The Company stated that its assessment is based, in part, on
the existence of insurance coverage.



Item 1119 of Regulation AB, Affiliations and Certain Relationships and Related
Transactions.

The information regarding this Item has been previously disclosed in a 424(b)(5)
filed on January 30, 2007 (Commission File No. 333-132809-47).



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).
