        <footnote id="F1">On June 1, 2009 Gevity HR, Inc. was acquired by TriNet Group, Inc. with TriNet paying $4.00 for each share of Gevity common stock outstanding (the Merger). Dispositions by reporting person in the Merger were approved in advance by the Gevity board of directors.</footnote>
        <footnote id="F2">In connection with the terms of the Merger, restricted stock held by reporting person subject to time vesting was converted into the $4.00 per share merger consideration.</footnote>
        <footnote id="F3">In connection with the terms of the Merger, each stock option was cancelled and reporting person received consideration equal to the number of shares subject of the option multiplied by the difference between the exercise price and $4.00, with no consideration being paid for stock options having exercise prices greater than $4.00.</footnote>
