        <footnote id="F1">For Section 16 purposes only, the increases in option exercise prices are deemed to be a cancellation of the old options and the grant of replacement options.  The other terms of the outstanding options (including the vesting of the options) remain unchanged.</footnote>
        <footnote id="F2">On February 18, 2008, the Reporting Person entered into an agreement with the Registrant to amend the exercise prices of certain eligible stock options.  The exercise prices of these eligible options were based on a formula set forth in the Registrant's outstanding warrant agreement, which provides for an exercise price per share equal to the 10-day trailing average closing price per share of the Registrant's common stock prior to the date of grant.  As a result, the exercise prices for these eligible options were less than the closing sale price per share of the Registrant's common stock on the dates of grant.  Pursuant to the amendment agreement, the exercise price per share of each of the eligible options will increase to the closing sale price per share of the Registrant's common stock on the date of grant of that eligible option.</footnote>
        <footnote id="F3">The amount shown in Column 9 reflects the number of Common Shares that may be acquired on exercise of Non-Employee Director Stock Options granted to the Reporting Person on September 21, 2006 pursuant to the 2004 Stock Incentive Plan and does not include shares that may be acquired upon exercise of outstanding Non-Employee Director Stock Options previously reported.</footnote>
