Pursuant to the Shareholders’ Agreement, each of TPG and JPMP have the right to elect two directors to the board of directors of the Company so long as it owns 10% or more of the outstanding common stock and one director so long as it owns 2% or more of the common stock. Additionally, the Shareholders’ Agreement places restrictions on each party’s right to transfer their respective shares of common stock without consent of the other party, and grants rights to the other party to participate on the same terms in mutually consented transfers. These provisions will be in effect for a limited time, and terminate earlier if the ownership interest of TPG and JPMP falls below certain levels.  Furthermore, the Shareholders’ Agreement provides that TPG and JPMP can cause the Company to register their shares of common stock in the Company under the Securities Act of 1933 and to maintain a shelf registration statement effective with respect to such shares.
