        <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 January 3, 2006, the reporting person was granted 100,000 shares of performance stock whereby 100,000 shares of common
 stock would be issued to the reporting person after the end of the performance period if a predetermined performance goal
 attributable to the Issuer was attained at any time during the performance period (i.e., January 1, 2006 through December
 31, 2008). The performance goal was met, based upon the information provided in the Issuer's press release issued on
 November 2, 2006; 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.</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 prior to the end of
 the performance period. The shares will be delivered earlier if the Issuer experiences a change in control prior to the end
 of the performance period and the reporting person is employed by the Issuer at such time.</footnote>
