(a) Effective as of the execution of this Agreement, each of the Lone Star Value Stockholders on behalf of itself and its respective Affiliates and Associates (as each is defined in Section 13, below) hereby severally and not jointly agrees that it will not, and that it will not permit any of its Affiliates or Associates to, (i) nominate or recommend for nomination any person for election at the 2016 annual meeting of the stockholders of the Company (the “2016 Annual Meeting”), directly or indirectly, (ii) submit any proposal for consideration at, or bring any other business before, the 2016 Annual Meeting, directly or indirectly, or (iii) initiate, encourage or participate in any “withhold” or similar campaign with respect to the 2016 Annual Meeting, directly or indirectly.

Bova and Timothy Whelan (each, a “Lone Star Nominee” and collectively, the “Lone Star Nominees”), each of whom has consented to such appointment and has agreed to serve on the Board, shall be appointed to the Board to fill the resulting vacancies from the increase of the size of the Board, effective on the Effective Date, (iii) the Board shall nominate each of the Lone Star Nominees and each other incumbent member of the Board for election to the Board at the 2016 Annual Meeting (collectively, the “2016 Board Nominees”) and (iv) the Company shall recommend, support and solicit proxies at the 2016 Annual Meeting for each of the 2016 Board Nominees as the Company solicited proxies for each nominee at the annual meeting of stockholders of the Company in 2015.

(d) All 2016 Board Nominees will be required to: (i) comply with all policies, procedures, processes, codes, rules, standards and guidelines applicable to members of the Board; (ii) keep confidential all Company confidential information and not disclose to any third parties discussions or matters considered in meetings of the Board or Board committees; and (iii) complete all reasonable and customary director onboarding documentation required by the Company in connection with the appointment or election of Board members.

(e) The Company agrees that if either Lone Star Nominee is unable to serve as a director, resigns as a director or is removed prior to the Termination Date (as defined in Section 2, below), then the Lone Star Value Stockholders shall have the ability to recommend a substitute person(s); provided that any substitute person recommended by the Lone Star Value Stockholders shall qualify as “independent” pursuant to Nasdaq Stock Market listing standards, and have relevant financial and business experience to fill the resulting vacancy.

Upon the approval of a replacement director nominee by the Nominating Committee and by the Board acting in good faith, the Board will take such actions as to appoint such replacement director to the Board no later than five business days after the Nominating Committee recommendation of such replacement director, and if consistent with the Board’s fiduciary duties, the Board will take such actions as to appoint such replacement director to the Board.

(f) The Company agrees that the Lone Star Nominees shall be considered along with all other Board members for Board committee appointments in connection with the Board’s annual review of committee composition.

(g) The Company agrees that prior to the Termination Date, the Board will not establish an Executive Committee of the Board or delegate to an existing or new committee of the Board responsibilities substantially similar to those of an Executive Committee of the Board.

(“ISS”) and Glass Lewis & Co., LLC (“Glass Lewis”) differs from the Board’s recommendation with respect to any matter other than nominees for election as directors to the Board, the Lone Star Value Stockholders shall have the right to vote in accordance with the recommendation of ISS and Glass Lewis with respect to such matters.

(i) The Company shall use its reasonable best efforts to hold the 2016 Annual Meeting no later than July 3, 2016.
