        <footnote id="F1">This represents the grant of a performance-based restricted stock unit award that provides for vesting at varying rates based on certain performance-based criteria.  Each restricted stock unit represents the right to receive one share of Common Stock at vesting.  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 FY10 through FY12 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 upon vesting of the award if the CAGR maximum target is met.</footnote>
        <footnote id="F2">This represents the grant of a performance-based restricted stock unit award that provides for vesting at varying rates based on certain performance-based criteria.  Each restricted stock unit represents the right to receive one share of Common Stock at vesting.  The extent and timing of the vesting of the units 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 FY10, FY11 and FY12.</footnote>
        <footnote id="F3">This represents the grant of a restricted stock unit award.  Each restricted stock unit represents the right to receive one share of Common Stock at vesting.  The restricted stock units will become vested at the rate of 30% of the shares on the 1st anniversary of the date of grant (which date of grant was 10/22/09), 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>
