In furtherance of the foregoing, the Company and the Stockholders agree to promptly hereafter hold a meeting or act by written consent for the purpose of electing the Bison Representatives as directors.

(b) The “ Bison Representatives ” shall initially be Louis N. Caballero and Douglas B. Trussler. At such time, if any, as either Bison Representative is unable to serve as a director, the Bison Representatives shall be such persons as shall be designated from time to time by Purchaser.

two (2) Business Days, and (with respect to each of the foregoing clauses (i) through (iii)) until such Event of Default is no longer existing, Purchaser shall have the right to appoint a majority of the members of the Board of Directors. In furtherance of the foregoing, upon the written demand by Purchaser, the Stockholders agree to hold a meeting or act by written consent to remove such number of existing directors (other than the Bison Representatives) as is necessary, and to cast the number of votes represented by all Interests in favor of persons designated by Purchaser at such time to replace such removed directors (such replacement directors and the Bison Representatives are collectively referred to as the “ Bison Default Representatives” ), in order that Purchaser will have designated at least a majority of the members of the Board of Directors.

(d) The number of authorized directors of the Company shall at no time exceed seven (7) without the written consent of Purchaser.

(e) The Company shall at all times maintain directors’ and officers’ liability insurance coverage for the Bison Representatives and the Bison Default Representatives in amounts adequate and customary for similarly situated public companies (and in no event less favorable to the Bison Representatives and the Bison Default Representatives than any other director). The Company shall promptly reimburse or advance all costs related to board attendance (including, without limitation, business class airfare and hotel accommodations) or the discharge of board duties incurred by the Bison Representatives and the Bison Default Representatives.

(f) If required of the all of the other directors, each of the Bison Representatives and, if applicable, the Bison Default Representatives shall complete a questionnaire, in substantially the form attached hereto as Exhibit A (as may be modified or replaced from time to time, the “ Questionnaire ”), prior to each election of directors of the Company during the term of this Agreement, or upon the death, resignation or removal of a director.

(b) In the event of removal, resignation, incapacity or death of any then Bison Representatives or Bison Default Representatives, the Stockholders or the Company, as the case may be, shall take all actions necessary and appropriate to cause the successor Bison Representatives or Bison Default Representatives to be elected as directors.

(c) The Stockholders or the Company, as the case may be, shall not vote their Interests to remove any director in contravention of any provision of this Agreement; provided , however , that the foregoing shall not preclude the removal of a director for cause.

3. No Liability for Election of Recommended Director . Neither the Company, Purchaser nor any Stockholder, nor any officer, director, stockholder, partner, employee or agent of such party, makes any representation or warranty as to the fitness or competence of the Bison Representatives or the Bison Default Representatives to serve as a director by virtue of such party’s execution of this Agreement or by the act of such party in voting for the Bison Representatives or the Bison Default Representatives pursuant to this Agreement or otherwise.

4. Grant of Irrevocable Proxy . Concurrently with the execution of this Agreement, each Stockholder agrees to deliver to Purchaser a duly executed Irrevocable Proxy and Power of Attorney substantially in the form attached hereto as Exhibit B (the “ Proxy ”), which shall be irrevocable during the term of this Agreement to the fullest extent permissible by law, with respect to the Interests. Each Stockholder expressly acknowledges that such Proxy is coupled with an interest. Each Stockholder hereby revokes any and all prior proxies, powers of attorney or similar authorizations with respect to the Interests to the extent related to the election of directors of the Company or otherwise related to this Agreement.

5. Manner of Voting . The voting of Interests pursuant to this Agreement may be effected in person, by proxy, by written consent or in any other manner permitted by applicable law.

6. Legending of Certificates . If so requested by Purchaser, each Stockholder agrees that the certificates representing the Interests shall bear a legend stating that they are subject to this Agreement and to an irrevocable proxy. Subject to the terms of Section 8, each Stockholder agrees that it shall not transfer any Interests without first having the aforementioned legend affixed to the certificates representing the Interests.

7. Splits, Dividends, etc . In the event of any transaction involving the issuance of securities or other equity interests to the Stockholders with respect to or in replacement of their existing holdings of the Company’s equity, the securities or other interests so issued shall be subject to this Agreement and shall be deemed to be incorporated into the provisions hereof and shall be endorsed with the legend set forth in Section 6.

Any transfer or assignment of any such Interests in violation of this Section 8(a) shall be void and be of no force or effect. All parties hereby agree that, in the event of a transfer of Interests in a public sale pursuant to Rule 144 (or any successor thereto) under the Securities Act of 1933, as amended, the legend referenced in Section 6 hereto shall be removed and this Agreement shall act as authority for the transfer agent to remove such legend in conjunction with the removal of the Securities Act legend pursuant to Rule 144 (or any successor thereto) under the Securities Act of 1933, as amended. In addition, each Stockholder agrees to notify Purchaser of the change in such Stockholder’s Interest and, if requested by Purchaser, execute an amended proxy to reflect the number of shares of capital stock owned directly or beneficially by the Stockholder following the transfer of Interests referenced above.

(b) The Company hereby agrees, and any person acquiring any shares of the Company’s capital stock from the Company is hereby on notice, that any issuance of such securities is conditioned upon such person’s execution and delivery to the parties of a Proxy and a joinder agreement in the form of Exhibit C prior to such issuance.
