        <footnote id="F1">Each share of performance stock represents a contingent right to receive one share of the Issuer's common stock.</footnote>
        <footnote id="F2">On April 1, 2008, the reporting person was granted 3,855 shares of performance stock whereby 3,855 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, 2008 through December
 31, 2010).The performance goal was met, based upon the information provided in the Issuer's press release issued on March 2,
 2009. However, 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.</footnote>
        <footnote id="F3">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.</footnote>
