§ Includes warrants held by WP X that are exercisable for a total of 25,327,646 shares of Common Stock, as further detailed in Item 5.

Items 5(a) and 5(b) are hereby amended by replacing them in their entirety with the following:

(a) WP X (i) is the beneficial owner of 46,159,252 shares of Common Stock (over which it exercises both voting and investment power) and (ii) is the beneficial owner of warrants exercisable for a total of 25,327,646 shares of Common Stock, collectively representing approximately 30.64% of the outstanding shares of Common Stock (percentages in this Item 5 are based on the 207,954,051 shares of MBIA Common Stock outstanding as of October 30, 2009, based on information included in MBIA’s Form 10-Q (for the period ended September 30, 2009), plus the 25,327,646 shares of Common Stock for which warrants issued to WP X are exercisable and that are included in the amount beneficially owned by WP X above). On December 3, 2009 , WP X received formal approval from the New York State Insurance Department which allows WP X to acquire voting rights with respect to the shares of MBIA Common Stock subject to the Voting Trust Agreement and the Voting Trust II Agreement. Effective as of December 10, 2009, WP X terminated the Voting Trust Agreement and the Voting Trust II Agreement in light of receiving such approval, and as a result WP X obtained voting power and became the direct beneficial owner of the 30,667,683 shares of MBIA Common Stock that had been held in such trusts.

The warrants that are exercisable for a total of 25,327,646 shares of Common Stock are composed of warrants, exercisable for a total of 11,502,704 shares of Common Stock, B-warrants exercisable for a total of 9,824,942 shares of Common Stock and B2-warrants exercisable for a total of 4,000,000 shares of Common Stock.

Due to their respective relationships with WP X and each other, each of the Warburg Pincus Reporting Persons may be deemed to beneficially own, in the aggregate, 71,486,898 shares of Common Stock. Each of WP X LP, WP X LLC, WP Partners, WP, WP LLC, Messrs. Kaye and Landy disclaims beneficial ownership of the shares of Common Stock and the warrants in which WP X has beneficial ownership, except to the extent of any indirect pecuniary interest therein. Except as described in this Item 5(a), no person listed in Item 2 of this Statement is a beneficial owner of the Common Stock or the warrants in which WP X has beneficial ownership.

On December 3, 2009, WP X received formal approval from the New York State Insurance Department which allows WP X to acquire voting rights with respect to the shares of MBIA Common Stock subject to the Voting Trust Agreement and the Voting Trust II Agreement. Effective as of December 10, 2009, WP X terminated the Voting Trust Agreement and the Voting Trust II Agreement in light of receiving such approval, and as a result WP X obtained voting power and became the direct beneficial owner of the 30,667,683 sha res of MBIA Common Stock that had been held in such trusts.

After reasonable inquiry and to the best of our knowledge and belief, the undersigned certify that the information set forth in this statement is true, complete and correct.
