SETTLEMENT AGREEMENT

Settlement Covenants.

Board Appointment. The Company has been discussing with a Class III director of the Company (the “Incumbent Director”) the possibility of such director retiring and not standing for re-election at the 2016 annual meeting of stockholders of the Company (the “2016 Annual Meeting”). The Company agrees that promptly following the execution of this Agreement, the Company will (i) accept the resignation of the Incumbent Director from the Board of Directors of the Company (the “Board”) and, to fill the vacancy created by accepting such resignation, appoint Thomas W. Dickson (the “New Director”) to the Board as a Class III director and (ii) issue a public statement to the effect that the Company is initiating a process to review strategic alternatives. As a Class III director, the New Director shall stand for election at the 2016 Annual Meeting together with the Company’s other nominees. The Board shall recommend (and shall not change such recommendation in a manner adverse to the New Director unless required to do so by the Board’s fiduciary duties) that the Company’s stockholders vote in favor of the Board’s entire slate (including the New Director) at the 2016 Annual Meeting, and the Company shall use its reasonable best efforts to cause the election of the New Director to the Company’s Board at the 2016 Annual Meeting (including soliciting proxies for the election of such New Director) and otherwise supporting such New Director for election in a manner no less rigorous and favorable than the manner in which the Company supports its other nominees.

Replacements. The Company agrees that if the New Director is unable to serve as a director, resigns as a director or is removed as a director prior to the expiration of the Standstill Period (as defined below), then the Investors shall have the ability to recommend a substitute person(s); provided that any substitute person recommended by the Investors shall qualify as “independent” pursuant to New York Stock Exchange (“NYSE”) listing standards, and have relevant financial and business experience to fill the resulting vacancy. In the event the Nominating and Governance Committee of the Board (the “Nominating Committee”) does not accept a substitute person recommended by the Investors, the Investors will have the right to recommend additional substitute person(s) for consideration by the Nominating Committee. Upon the acceptance of a replacement director nominee by the Nominating Committee, the Board will take such actions as to appoint such replacement director to the Board no later than 5 business days after the Nominating Committee recommendation of such replacement director.

Committees of the Board. The Company agrees that following the Board’s establishment of a committee of the Board to oversee the strategic review contemplated by Section 1(a)(ii) (the “Board Committee”), the New Director shall be appointed as a member of the Board Committee and shall be considered along with all other Board members for Board committee appointments in connection with the Board’s annual review of committee composition.

2016 Annual Meeting.

Effective immediately, each Investor hereby irrevocably withdraws and renounces any intention to nominate any person for election as a director at the 2016 Annual Meeting and agrees not to bring any nominations or other business or proposals before or at the 2016 Annual Meeting.

At the 2016 Annual Meeting, and at each special meeting of stockholders held prior to the expiration of the Standstill Period, each of the Investors agrees to cause the Investor Shares (as defined below) to be present for purposes of establishing a quorum and to cause the Investor Shares to be voted by proxy in favor of (i) the election of any director nominated by the Board and (ii) otherwise in accordance with the Board’s recommendation, including in favor of any other matter recommended for stockholder approval by the Board; provided that to the extent that the recommendation of Institutional Shareholder Services Inc. (“ISS”) or Glass Lewis & Co., LLC (“Glass Lewis”) differs from the Board’s recommendation with respect to any matter other than the election of directors to the Board, the Investors shall have the right to vote the Investor Shares in accordance with the recommendation of ISS or Glass Lewis with respect to such matters; provided further that the Investors may vote the Investor Shares in their discretion with respect to any tender offer, exchange offer, merger, consolidation, business combination or other change-of-control transaction of the Company. “Investor Shares” means any and all shares of voting stock of the Company held beneficially or of record as of an applicable record date by the Investors and, with respect to Investors that are entities, the Affiliates and Associates (as each term is defined below) of such Investors, and, with respect to Investors that are individuals, the Family Members (as defined below) of such Investor.
