Pursuant to the terms of the Settlement Agreement the Issuer agreed that concurrent with or prior to the next regularly scheduled meeting of the Board, but in any event no later than November 15, 2011, the Board shall take all necessary actions to (i) increase the size of the Board from seven (7) to nine (9) members, effective as of the 2011 annual meeting of stockholders of the Issuer (the “2011 Annual Meeting”) and (ii) nominate Jeffrey S.

Traub for election to the Board at the 2011 Annual Meeting as a Class III director with a term expiring at the Company’s 2013 annual meeting of stockholders (Messrs. McCreary and Traub, the “Starboard Appointees”).  In accordance with the Settlement Agreement, prior to the nomination of the Starboard Appointees, the Compensation and Nominating Committee of the Board shall have reviewed and reasonably approved the qualifications of the Starboard Appointees to serve as members of the Board and recommended to the Board that the Board nominate the Starboard Appointees for election at the 2011 Annual Meeting.

The Issuer further agreed to create an independent advisory committee of the Board following the conclusion of the 2011 Annual Meeting, but in any event no later than February 15, 2012, and to appoint at least one of the Starboard Appointees to such committee.

Starboard agreed, among other things, (i) to withdraw its nomination letter, dated September 12, 2011, nominating Robert Kramer, Jeffrey S. McCreary, Jeffrey C. Smith and Kenneth H. Traub as director candidates to be elected to the Board at the 2011 Annual Meeting, (ii) to withdraw its demand for a stockholder list and other materials pursuant to Section 220 of the Delaware General Corporation Law, (iii) not to nominate any person for election at the 2011 Annual Meeting, (iv) not to submit any proposal for consideration at, or bring any other business before, the 2011 Annual Meeting, directly or indirectly.
