If and when elected, Mr. Riley will be appointed to the Compensation Committee and Nominating Corporate Governance Committee of the Board, assuming he satisfies applicable legal requirements and listing standards. The Nominating and Corporate Governance Committee will use its reasonable best efforts to appoint one additional member to the Board as promptly as practicable, who shall be unanimously approved by the committee. RIP agreed to withdraw its nomination letter for the 2008 annual meeting. Pursuant to the Settlement Agreement, the Reporting Persons agreed to vote in favor of the Board's slate of nominees at the 2008 annual meeting and all further annual meetings so long as the slate includes Mr. Riley (or his designated replacement) and he has consented to be on such slate. The Reporting Persons also agreed to vote in favor of the proposals submitted by the Board at the 2008 annual meeting and all further annual meetings so long as the slate includes Mr. Riley (or his designated replacement) and he has consented to be on such slate and provided that Mr. Riley (or his designated replacement) has voted in favor of such proposal as a member of the Board. Pursuant to the Settlement Agreement, the Reporting Persons agreed until at least June 30, 2009 and so long as Mr. Riley (or his designated replacement) serves on the Board to various standstill provisions. Under the standstill provision, subject to specified exceptions, the Reporting Persons and their affiliates cannot, without specified prior consent of the Board: (i) effect, offer, participate, propose to effect, or cause any (x) tender offer or exchange offer, merger, acquisition or other business combination involving the Issuer or any of its subsidiaries; (y) any form of business combination or acquisition or other transaction relating to a material amount of assets or securities of the Company or any of its subsidiaries or (z) any form of restructuring, recapitalization or similar transaction with respect to the Issuer or any of its subsidiaries; (ii) acquire, offer or propose to acquire any of the Company's voting securities (or beneficial ownership thereof), or rights or options to acquire any voting securities if it would result in the Reporting Persons and its Affiliates beneficially owning more that 9.9% of the then outstanding Common Stock; (iii) engage in any solicitation of proxies or consents to vote in opposition to the recommendation of the Board; (iv) knowingly seek to influence any person with respect to the voting of any securities of the Company in opposition to the recommendation of the Board; (v) knowingly seek to control or influence the management or the policies of the Company; (vi) seek to control the Board or initiate or take any action to obtain representation on the Board, or seek the removal of any director from the Board; (vii) seek to amend any provision of the Company's Amended and Restated Articles of Incorporation or Amended and Restated Bylaws except as may be approved by the Board; (viii) grant any proxy rights with respect to the Common Stock to any person not designated by the Company; (ix) call or seek to have called any meeting of the shareholders of the Company; (x) propose any matter for submission to a vote of the shareholders of the Company; (xi) execute any written consents, waiver or demand with respect to the Common Stock; (xii) unless required by law, make any public disclosure, announcement or statement in support of any non-Issuer proxy solicitation, concerning the matters described in (i) through (x) above, or negatively commenting upon the Issuer; and (xiii) enter into any agreements with any third party with respect to any of the foregoing. The standstill provisions terminate when Mr. Riley (or his designated replacement) first ceases to serve on the Board, but no earlier than June 30, 2009. CUSIP No. 827057100 13D Page 8 The Settlement Agreement may be terminated by the non-breaching party in the event of a material breach by any party, subject to a five-business day cure period.
