Explanation of Responses:

( 1 )Shares sold by Issuer to cover taxes associated with settlement of Restricted Stock Units. ( 2 )The grant consists of three separate issuances of Restricted Stock Units, each with vesting subject to the Reporting Person's continued service to the Issuer. The first is 73,696 units vesting as follows: 1/16th of the units vest quarterly commencing December 15, 2019. The second is 40,887 units, for which vesting was subject to the satisfaction of both performance-based conditions and time-based criteria. Attainment regarding the performance-based conditions was determined by the Issuer's Board of Directors based on the Issuer's 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. ( 3 )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.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
