7. The grant consists of three separate issuance of Restricted Stock Units, each with vesting subject to the Reporting Person's continued service to the Issuer. The first is 1,500 units vesting as follows: 1/16th of the units vest quarterly commencing December 15, 2018. The second is 1,012 units, for which vesting was subject to the satisfaction of both performance-based conditions and timebased criteria. The performance-based conditions were deemed met and exceeded by the Issuer's Board of Directors, and the time-based vesting criteria are as follows: 1/4th of the units vested on September 15, 2019 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, 2021.

8. Each restricted stock unit or performance unit represents a contingent right to receive one share of the Issuer's common stock.

9. These performance stock units are split in two halves, with vesting of each subject to the satisfaction of both performance- and time-based conditions. Performance-based conditions will be satisfied if financial targets, determined by the Issuer, are met for fiscal year 2021 for the first half and fiscal year 2023 for the second half. If the performance-based conditions for fiscal year 2021 are achieved, then the first half will vest based on performance with the following timing: 16.6% will vest on each of September 15, 2021, September 15, 2022, and September 15, 2023, subject to the Reporting Person's continued service to the Issuer. The second half will vest on September 15, 2023 based on achievement under the performance-based conditions for fiscal year 2023, subject to the Reporting Person's continued service to the Issuer.

10. The Restricted Stock Units vest as follows: 1/4 of the units vested on December 15, 2018 and an additional 1/16th of the units vest quarterly thereafter, subject to the Reporting Person's continued service to the Issuer through each such vesting date.

11. The vesting of these Restricted Stock Units ("PSUs") is subject to the satisfaction of performance-based conditions, which will be satisfied if certain performance targets, determined by the Issuer, are met over the course of the Issuer's 2021 fiscal year. If the performance-based conditions are not met, then none of the units will vest. If the performance-based conditions are achieved, then all of the units will vest on September 15, 2021.
