        <footnote id="F1">Pursuant to the Issuer's 2004 Stock Incentive Plan, the Reporting Person was granted restricted stock units for service as a non-employee director of the Issuer.  Each restricted stock unit represents a contingent right to receive one share of Common Stock of the Issuer upon the Reporting Person's termination of service as a Board member of the Issuer.  The restricted stock units vest upon the earlier of (i) June 5, 2008 and (ii) the 2008 annual meeting of the stockholders of the Issuer.</footnote>
        <footnote id="F2">The restricted stock units have no voting rights, may not be transferred or otherwise disposed while the Reporting Person is a director of the Issuer and pay dividends in the form of additional restricted stock units at the same time dividends are paid on the Common Stock in an amount equal to the result obtained by dividing (i) the product of (x) the amount of units owned by the Reporting Person on the record date for the dividend on the Common Stock times (y) the dividend per share on the Common Stock by (ii) the closing price of a share of Common Stock on the payment date for the dividend on the Common Stock, which restricted stock units vest immediately upon payment.</footnote>
