        <footnote id="F1">On February 11, 2008, the Reporting Person, a non-employee director of the Issuer, filed a Form 4 reporting the grant of a nonqualified stock option to purchase 12,000 shares under the Issuer's 1995 Equity Incentive Plan.  The 1995 Equity Incentive Plan does not provide for grants to non-employee directors of the Issuer and as a result, the Form 4 filed on February 11, 2008 was in error.</footnote>
