        <footnote id="F2">The first 5,000 are scheduled to vest 1/12th at the end of each month in the 12 months following 7/31/2008. The second 5,000 are scheduled to vest on 7/31/2010 and the third 5,000 on 7/31/2011. If the director leaves the Board prior to 7/31/2009, any unvested options are forfeited. If the director is on the Board at 7/31/2009, all the options will vest as per the above described vesting schedule regardless of whether the director remains on the Board after 7/31/2009.</footnote>
