Explanation of Responses:

1. 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.

2. The number of shares reported in Column 9 of Table II represents the 2019 Performance Stock Unit ("PSU) and the Total Shareholder Return ("TSR") grants less the number of PSU shares vested as of this Transaction Date.

3. 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.
