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 us 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.

     Related Transactions.
