        <footnote id="F3">Performance Units are not assigned an exercise price.</footnote>
        <footnote id="F4">Reported number of Performance Units acquired is based on GSI attaining 100% of the performance target for fiscal years 2011 and 2012. If GSI exceeds the performance target, the reporting person may receive up to 1.5 times the reported number.
