The information set forth in Items 4, 5 and 6 is incorporated herein by reference.
Includes open market purchases of 2,610,097 shares of Common Stock pursuant to open market transactions on March 9, 10 and 12, 2009 by WP X, as set forth on Exhibit 99.2, representing approximately 1.11% of the outstanding shares of Common Stock. The remaining increase in beneficial ownership in this box is due to the inclusion of certain warrants, the exercise of which may be subject to approval by the New York State Insurance Department that WP X expects to receive within 60 days (provided that no assurances can be made as to when or whether such approval will be received). The warrants held by WP X are exercisable for a total of 25,327,646 shares of Common Stock, as further detailed in Item 5. In the event the warrants held by WP X are exercised prior to receipt of such regulatory approval, the underlying shares of Common Stock will be placed into a voting trust agreement.
