Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) The vesting of these Restricted Stock Units is subject to the satisfaction of both performance-based conditions and time-based criteria. The performance-based conditions will be satisfied if certain financial targets, determined by the Issuer, are met over the course of the Issuer's 2019 fiscal year. If the performance-based conditions for fiscal year 2019 are not met, then none of the shares will vest. If the performance-based conditions for fiscal year 2019 are achieved, as determined by the Issuer, then units will vest as the time-based criteria are satisfied. The time-based vesting criteria are as follows: 1/4th of the units vest on the one year anniversary of the vesting commencement date of September 15, 2018 and an additional 1/16th of the units will vest quarterly thereafter, subject to (1) the previously mentioned fiscal year 2019 performance-based conditions being met, and (2) the Reporting Person's continued service to the Issuer through each such vesting date.
(2) Each Performance Restricted Stock Unit ("Performance RSU") represents a contingent right to receive one share of the Issuer's common stock. Between 0% to 110% of the reported target number of Performance RSUs may be earned, based on the Company's total shareholder return percentile ranking relative to the software companies in the S&P Software and Services Select Industry Index for a three-year cumulative performance period commencing August 1, 2018 and ending July 31, 2021 (the "Performance Measurement Period"). All earned Performance RSUs will vest at the end of the Performance Measurement Period, subject to the Reporting Person's continued service to the Issuer through such vesting date.
(3) The Restricted Stock Units vest as follows: 1/16th of the units vest quarterly commencing December 15, 2018, subject to the Reporting Person's continued service to the Issuer through each such vesting date.
