       MBIA Announces $1 Billion Share Repurchase Authorization


    ARMONK, N.Y.--(BUSINESS WIRE)--Feb. 1, 2007--MBIA Inc. (NYSE: MBI)
announced today that the Company's board of directors has authorized
the repurchase of up to $1 billion of its outstanding shares in the
open market. This new program will replace the approximately 5 million
shares remaining in the board's August 2004 authorization.

    C. Edward Chaplin, MBIA Chief Financial Officer said, "The new
share repurchase program reflects our strong financial position and
will allow us to manage toward a more efficient capital structure. A
share repurchase program is an excellent way to return cash to
shareholders, thereby improving return on equity and enhancing
shareholder value."

    The Company's ability to buy back stock will be dependent on the
amount of dividends paid to it by MBIA Insurance Corp., which requires
prior approval of the New York State Insurance Department.
Acquisitions in the repurchase program will be made from time to time
in the open market and/or in private transactions as permitted by
securities laws and other legal requirements. The program may be
suspended or discontinued at any time without prior notice.
