1.2 Purchase Agreement and Financing. At any meeting of stockholders of the Company, however called, and in any action by written consent of the Company stockholders (the “Stockholders Meeting”), the Stockholders shall vote all of their respective Stockholders Shares to be voted in favor of the approval of the Financing, and shall not vote in any manner against such Financing.

1.3 Successors. The provisions of this Agreement shall be binding upon the successors in interest to any of the Stockholder Shares.

1.4 Other Rights. Except as provided by this Agreement or any other agreement entered into in connection with the Financing, the Stockholder shall exercise the full rights of a holder of capital stock of the Company with respect to the Stockholder Shares, respectively.

1.5 No Disposition or Encumbrance of Stock. The Stockholder hereby covenants and agrees that, until this Agreement has been terminated in accordance with its terms, except as contemplated by this Agreement, such Stockholder shall not offer or agree to sell, transfer, tender, assign, hypothecate or otherwise dispose of, grant a proxy or power of attorney with respect to, or create or permit to exist any security interest, lien, claim, pledge, option, right of first refusal, agreement, limitation on such Stockholder’s voting rights, charge or other encumbrance of any nature whatsoever (“Encumbrance”) with respect to the Stockholder Shares, directly or indirectly, initiate, solicit or encourage any person to take actions which could reasonably be expected to lead to the occurrence of any of the foregoing; provided, however, that the Stockholder may assign, sell or transfer any Stockholder Shares provided that any such recipient of the Stockholder Shares has delivered to the Company a written agreement in a form reasonably satisfactory to TCP that the recipient shall be bound by, and the Stockholder Shares so transferred, assigned or sold shall remain subject to this Agreement.

1.6 Company Cooperation. The Company hereby covenants and agrees that it will not, and the Stockholder irrevocably and unconditionally acknowledges and agrees that the Company will not (and waives any rights against the Company in relation thereto), recognize any Encumbrance or agreement on any of the Stockholder Shares subject to this Agreement unless the provisions of Section 1.5 have been complied with. The Company agrees to use its reasonable best efforts to ensure that at any time in which any stockholder approval is required, it will cause the Stockholder to vote in favor of the Financing, to become party to and bound by the terms and conditions of this Agreement and the Stockholder Shares held by the Stockholder to be subject to the terms and conditions of this Agreement.
