3

(c)                                  Effective as of the Closing Date, each of the Sponsor Stockholders shall vote all of its Stockholder Shares and shall take all other necessary or desirable actions within its control (whether in the capacity as a stockholder or otherwise, and including, without limitation, attendance at meetings in person or by proxy for purposes of obtaining a quorum and execution of written consents in lieu of meetings), and the Company shall take all necessary and desirable actions within its control (including, without limitation, including in the slate of nominees recommended by the Board the persons designated pursuant to this Section 2.01), so that the following Sponsor Directors shall be elected to the Board at each meeting of the stockholders of the Company:
