        <footnote id="F1">This represents the grant of a performance-based restricted stock award that has restrictions that lapse at varying rates based on certain performance-based criteria. The award has an &quot;overdrive&quot; feature that provides that if the Compound Annual Growth Rate (&quot;CAGR&quot;) of the Company's core EPS for FY09 through FY11 is in excess of a certain specified percentage the reporting person is entitled to additional shares. The number of shares listed in Column 4 of Table 1 represents the maximum of shares that may be issued pursuant to the award if the CAGR maximum target is met.</footnote>
        <footnote id="F2">This represents the grant of a performance-based restricted stock award that has restrictions that lapse at varying rates based on certain performance-based criteria. The extent and timing of the lapse of restrictions on the shares subject to the award are based on comparisons of the increase in the market price of the Company's stock and the S&amp;P 500 Composite Stock Index (assuming in each case a reinvestment of dividends) during each of FY09, FY10 and FY11.</footnote>
        <footnote id="F3">This represents the grant of a restricted stock award that has restrictions that lapse at the rate of 30% of the shares on the 1st anniversary of the date of grant (which date of grant was 10/22/08), and 30% of the shares on the 2nd anniversary of the date of grant, and the remaining 40% of the shares on the 3rd anniversary of the date of grant, provided that in all instances the reporting person is an employee of, or consultant (as defined in the relevant Stock Incentive Plan) to the Company or subsidiary.</footnote>
        <footnote id="F4">This represents a performance-based restricted stock award that was granted on October 11, 2005 with restrictions that lapse at varying rates based on certain performance-based criteria. The award included an &quot;overdrive&quot; feature that provided that if the Compound Annual Growth Rate (&quot;CAGR&quot;) of the Company's core EPS for FY06 through FY08 was in excess of a certain specified percentage the reporting person would be entitled to additional shares. The number of shares listed in Column 4 of Table 1 represents the maximum of shares that would have been issued pursuant to the award if the CAGR maximum target had been met.  On October 22, 2008, the reporting person forfeited all of the shares subject to the award because the CAGR minimum target was not met.</footnote>
