Pursuant to the terms of the Agreement, Mr. Breeden and Mr. Fields will be included in the Company’s slate of director nominees at its 2008 Annual Meeting of Shareholders. In addition, Breeden Capital, Mr. Breeden and Mr. Fields have agreed that, so long as a Breeden Capital nominee remains on the Board of Directors of the Company, Breeden Capital, Mr. Breeden and Mr. Fields:

Breeden Capital, Mr. Breeden and Mr. Fields have also agreed not to sell, transfer or otherwise dispose of any of the Company’s common shares beneficially owned by them from the date of the Agreement until (1) with respect to Breeden Capital, after the date of the 2008 Annual Meeting of Shareholders and (2) with respect to Mr. Breeden or Mr. Fields, until after such time as they are in compliance with the Company’s Director Share Ownership Guidelines.
