(1) Warburg Pincus Private Equity X, L.P., a Delaware limited partnership, together with Warburg Pincus X Partners, L.P., an affiliated Delaware limited partnership (together, "WP X"), is the holder of 68,366,000 shares of Common Stock, 1,709,150 shares of Convertible Participating Voting Preferred Stock, Series B, no par value per share and liquidation preference $4.60 per share ("Series B Preferred Stock"), which convert into 786,209,000 shares of Common Stock upon approval of the Stockholder Proposals (as defined in Note 7), and the Warrant exercisable for 86,625,000 shares of Common Stock or 188,315 shares of Series B Stock, as applicable, as described below in Note 6. (Continued in Footnote 2)
(2) Warburg Pincus X, L.P., a Delaware limited partnership ("WP X LP"), is the general partner of WP X; Warburg Pincus X, LLC, a Delaware limited liability company ("WP X LLC") is the general partner of WP X LP; Warburg Pincus Partners, LLC, a New York limited liability company ("WP Partners") is the sole member of WP X LLC; and Warburg Pincus & Co., a New York general partnership ("WP") is the managing member of WP Partners. Warburg Pincus LLC, a New York limited liability company ("WP LLC") manages WP X, and Messrs. Charles R. Kaye and Joseph P. Landy are each a Managing General Partner of WP and Managing Member and Co-President of WP LLC. The Common Stock, Series B Preferred Stock and the Warrant described above (collectively, the "Securities") are currently held by Warburg Pincus Private Equity X, L.P.; however, Warburg Pincus Private Equity X, L.P. contemplates allocating a portion of the Securities to Warburg Pincus X Partners, L.P.
(3) By reason of the provisions of Rule 16a-1 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), as a Partner of WP and a Member and Managing Director of WP LLC, Mr. David A. Coulter may be deemed to be the beneficial owner of the Common Stock, the Series B Stock and the Warrant held by WP X.
(4) Pursuant to Rule 16a-1(a)(4) of the Exchange Act, Mr. David A. Coulter herein states that this filing shall not be deemed an admission that he is the beneficial owner of any of the Common Stock, the Series B Stock or the Warrant covered by this Statement. Mr. Coulter disclaims beneficial ownership of the Common Stock, the Series B Stock and the Warrant, except to the extent of his pecuniary interest in such Common Stock, Series B Stock or Warrant.
(5) The Warrant is exercisable at $0.22 per share of Common Stock (or, in the event the Warrant is exercised for Series B Stock, an amount equal to $0.22 per share of Common Stock on an as converted basis), subject to adjustments for certain issuances of common stock, stock splits, stock subdivisions, stock reclassifications, stock combinations, other distributions, certain repurchases, business combinations and similar actions.
(6) The Warrant is exercisable, in whole or part, to purchase 86,625,000 shares of Common Stock, if the Stockholder Proposals (as defined in Note 7) have been approved, or exercisable to purchase 188,315 shares of Series B Stock (or 86,625,000 shares of Common Stock on an as-converted basis), if the Stockholder Proposals have not been approved.
(7) WP X holds 1,709,150 shares of Series B Stock (786,209,000 shares of Common Stock on an as-converted basis). Each share of Series B Stock mandatorily converts into 460 shares of Common Stock, subject to customary anti-dilution adjustments, upon the approval of the holders of the Common Stock to approve (i) an increase in the number of authorized shares of Common Stock to at least 10,000,000,000 shares or a larger number that the Board of Directors determines in its reasonable judgment is necessary to permit STSA to comply with its obligations under agreements entered into in connection with certain recapitalization transactions that occurred on August 26, 2010 and (ii) the conversion of shares of Series B Stock and Series D Stock (as defined below) into, and the exercise of each of the Warrant and THL Warrant for, shares of Common Stock (the "Stockholder Proposals"). (Continued in Footnote 8)
(8) The "THLWarrant" has the same terms and conditions, and permits its holder to purchase the same number of shares of Common Stock or Series B Stock, as applicable, as the Warrant. On August 26, 2010, STSA sold 3,881,700 shares of Series D Convertible Participating Voting Preferred Stock, no par value and liquidation preference $4.60 per share (the "Series D Stock") to multiple investors in a private placement. Each share of Series D Stock mandatorily converts into 460 shares of Common Stock, subject to customary anti-dilution adjustments, upon approval of the Stockholder Proposals.
(9) Convertible Participating Voting Preferred Stock, Series B, no par value per share and liquidation preference of $4.60 per share ("Series B Shares").
