        <footnote id="F1">Grant to the Reporting Person of a stock option under the Issuer's Amended and Restated 2002 Stock Option Plan (the &quot;Plan&quot;). 1/36th of the shares subject to the option vest each month after 11/1/08, provided, if the Reporting Person suffers an involuntary termination without cause or a resignation for good reason in connection with a change in control of the Issuer (as defined in the Issuer's Change in Control Severance Plan (the &quot;Severance Plan&quot;)), the unvested shares subject to the option will vest in full.  The option expires ten years after the date of grant.</footnote>
        <footnote id="F2">Grant to the Reporting Person of a stock option under the Plan.  1/48th of the shares subject to the option vest each month after 12/17/11, provided, if the Reporting Person is terminated without cause or resigns for good reason (as defined in the stock option agreement) at any time at which the change in control provisions of the Severance Plan are not applicable, then, in each case, the vesting of the options will be accelerated with respect to the number of shares that would otherwise have vested in the 6 months following termination of employment.  Additionally, if the Reporting Person suffers an involuntary termination without cause or a resignation for good reason in connection with a change in control of the Issuer (as defined in the Severance Plan), the unvested shares subject to the option will vest in full.  The option expires ten years after the date of grant.</footnote>
