Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) Each share of Performance Stock represents a contingent right to receive one share of the Issuer's common stock.
(2) On April 2, 2007, the reporting person was granted 4,366 shares of performance stock whereby 4,366 shares of common stock would be issued to the reporting person after the end of the performance period if a pre-determined performance goal attributable to the Issuer was attained at any time during the performance period (i.e; January 1, 2007 through December 31, 2009). The performance goal was met, based upon the information provided in the Annual Report on Form 10-K for the fiscal year ended December 31, 2007 filed with the Securities and Exchange Commission on 5/16/2008. However, the delivery of the shares of stock will not occur until after the end of the performance period since the delivery of the shares requires the certification by the Issuer's compensation committee that the related performance goal was satisfied, which certification is expected to occur as soon as practicable following the end of the performance period.
(3) Notwithstanding the satisfaction of the performance goal for the performance stock, the issuance of the shares subject to the grant is conditioned on the reporting person not experiencing a termination of service for any reason other than termination without cause, good reason, death or disability prior to the end of the performance period. The shares will be delivered earlier if the issuer experiences a change in control or experiences a termination of service without cause, good reason, death or disability prior to the end of the performance period and the reporting person is employed by the Issuer at such time.
