        <footnote id="F1">The grant consists of three separate issuances of Restricted Stock Units. The first is 73,696 units vesting as follows: 1/4th of the units vest on September 15, 2020, and 1/16th of the units vest quarterly thereafter. The second is 40,887 units, for which vesting was subject to the satisfaction of both performance-based conditions and timebased criteria. Attainment of performance-based conditions was determined by the Issuer based on results for FYE July 31, 2020, and the time-based vesting criteria are as follows: 1/4th of the units vested on September 15, 2020 and an additional 1/16th of the units will vest quarterly thereafter. The third consists of units for which vesting will be determined based on the Issuer's total shareholder return percentile ranking relative to a set peer group, over a three-year period ending on July 31, 2022.</footnote>
        <footnote id="F2">The number of shares reported in Column 9 of Table II represents the 2019 Performance Stock Unit (&quot;PSU) and the Total Shareholder Return (&quot;TSR&quot;) grants less the number of PSU shares vested as of this Transaction Date.</footnote>
        <footnote id="F3">The Restricted Stock Units vest as follows:  1/16th of the units vest quarterly commencing December 15, 2020, subject to the Reporting Person's continued service to the Issuer through each such vesting date.</footnote>
