     3. Nomination of Ramius Nominee.

          (a) The Company will include one candidate previously recommended to the Company by the Ramius Group in writing, as determined by the Governance and Nominating Committee and the Board of Directors (the “Board”) of the Company in their sole discretion, as a nominee as part of management’s slate for election as a director of the Company at the Annual Meeting (the “Ramius Nominee”). The Company will recommend, support and solicit proxies for the election of the Ramius Nominee in the same manner as for the Company’s other nominees for election at the Annual Meeting. The size of the Board of Directors giving effect to the election of directors at the Annual Meeting will not exceed eight (8).

          (b) The Company agrees that if the Ramius Nominee resigns or is otherwise unable to serve as a director or is removed for cause as a director, the Ramius Group shall be entitled to designate an individual to replace the Ramius Nominee who (i) qualifies as “independent” under the Nasdaq corporate governance standards, (ii) is not an Affiliate of any member of the Ramius Group, (iii) has relevant business and financial experience, and (iv) is reasonably acceptable to the Governance and Nominating Committee of the Company. In the event the Governance and Nominating Committee does not accept a replacement director(s) recommended by the Ramius Group, the Ramius Group will have the right to recommend additional replacement director(s) for consideration by the Governance and Nominating Committee. Upon the acceptance of a replacement director nominee by the Nominating and Corporate Governance Committee, the Board will appoint such replacement director to the Board no later than five (5) business days after the Nominating and Corporate Governance Committee’s recommendation of such replacement director (any such replacement director appointed in accordance with the provisions of this Section 3(b) shall be referred to as the “Ramius Nominee” for the purposes of this Agreement).

     4. Standstill Restrictions.

          (a) Each member of the Ramius Group agrees that, from the date of this Agreement until the date that is the earlier of (x) ten (10) business days prior to the deadline for the submission of stockholder nominations for the 2011 annual meeting of stockholders (the “2011 Annual Meeting”) and (y) one year from the date of this Agreement (the “Standstill Period”), neither it nor any of its Affiliates or Associates under its control or direction will, and it will cause each of its Affiliates and Associates under its control not to, directly or indirectly, in any manner:

               (ii) purchase or cause to be purchased or otherwise acquire or agree to acquire beneficial ownership (as determined under Rule 13d-3 promulgated under the Exchange

               (iii) form, join or in any way participate in any “group” (within the meaning of Section 13(d)(3) of the Exchange Act) with respect to the Common Stock (other than a “group” that includes any Affiliates or Associates of any member of the Ramius Group or all or some lesser number of the persons identified as part of the Ramius Group, but does not include any other members who are not an Affiliate or Associate of any member of the Ramius Group or otherwise currently identified as Ramius Group members as of the date hereof);

               (iv) deposit any Common Stock in any voting trust or subject any Common Stock to any arrangement or agreement with respect to the voting of any Common Stock, other than any such voting trust, arrangement or agreement solely among the Ramius Group;

               (v) control or seek to control the Board, other than through non public communications with the officers and directors of the Company;

               (vi) seek or encourage any person (other than any member of the Ramius Group) to submit nominations in furtherance of a “contested solicitation” for the election or removal of directors with respect to the Company or any solicitation or nomination pursuant to Rule 14a-11 under the Exchange Act;

               (vii) (1) make any proposal for consideration by stockholders at any meeting of stockholders or action by consent in lieu thereof or (2) make any public proposal with respect to a merger, acquisition, disposition or other business combination involving the Company or any of its subsidiaries; provided, however, that nothing herein will limit the ability of (x) any member of the Ramius Group, or its respective Affiliates and Associates, except as otherwise provided in Section 5, to vote its shares of Common Stock on any matter submitted to a vote of the stockholders of the Company or (y) the Ramius Group to announce its opposition to any Board approved proposals related to a merger, acquisition, disposition of all or substantially all of the assets of the Company or other business combination involving the Company;

               (viii) seek, alone or in concert with others, representation on the Board or the removal of any member of the Board, except as specifically contemplated in Section 3; or

          (b) Notwithstanding anything contained herein to the contrary, except as expressly provided in Section 5, each member of the Ramius Group shall be entitled to:

               (i) vote their shares on any proposal duly brought before the Annual Meeting, or otherwise vote on any matter as each member of the Ramius Group determines in its sole discretion; and

          (c) As used in this Agreement, the terms “Affiliate” and “Associate” shall have the respective meanings set forth in Rule 12b-2 promulgated by the SEC under the Exchange Act.

          (d) In the event that the Company is in material breach of its obligations under this Agreement, including, without limitation, a failure to comply in any respect with the provisions of Section 3 of this Agreement, and such breach is not cured within 30 days after written notice thereof is provided to the Company by the Ramius Group, then in addition to any other remedies that the members of the Ramius Group may have, the provisions of this Section 4 shall also terminate.

          (e) In the event that the Ramius Group is in material breach of its obligations under this Agreement, and such breach is not cured within 30 days after written notice thereof is provided to the Ramius Group by the Company, then in addition to any other remedies that the Company may have, the provisions of Section 3 shall also terminate.

     5. Actions by the Ramius Group. At the Annual Meeting, the Ramius Group shall vote, and cause their respective officers, directors, employees and agents to vote, all of the shares of Common Stock beneficially owned by them for (i) each of the Company’s nominees for election to the Board and (ii) the ratification of the appointment of the Company’s independent auditors.
