        <footnote id="F1">On October 1, 2008, COMSYS IT Partners Inc.'s (the &quot;Company&quot;) Compensation Committee (the &quot;Committee&quot;) concluded that the annual EBITDA bonus target for its 2008 executive compensation bonus plan (the &quot;Original EBITDA Target&quot;) was unattainable, and replaced the annual target with a new EBITDA bonus target for the final six months of 2008 (the &quot;New EBITDA Target&quot;) that was lower on an annualized basis than the Original EBITDA Target by approximately 22%.  A portion of Mr. Barker's previous stock option grant on October 1, 2004, was subject to vesting based on meeting the Original EBITDA Target.  As a result of the above adjustments, the stock options subject to the performance vesting were reduced by approximately 25%.  If the New EBITDA Target is met, 50% of the original awards will vest.  If the New EBITDA Target is exceeded, up to 75% of the original awards will vest.</footnote>
