        <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 FY08 through FY10 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">Column 5 of Table I includes 533 shares acquired on June 30, 2007 under the 2002 Employee Stock Purchase Plan of Jabil Circuit, Inc.</footnote>
        <footnote id="F3">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 specified two-month periods in each of 2008, 2009 and 2010.</footnote>
        <footnote id="F4">Stock Appreciation Rights shall vest at the rate of one-twelfth of the initial shares subject to the award one year and three months after the date of grant (which date of grant was 10/24/2007), with an additional one-twelfth of the initial shares subject to the award vesting on the same calendar date of each successive three month period thereafter, with, as a result, all of the initial shares subject to the award vesting by four years from 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 a subsidiary.</footnote>
