Explanation of Responses:

( 1 )These PSUs cliff vest at the end of the three-year performance period based on the average performance of the three one-year performance periods. One-year financial targets for each of the three performance measurement periods were set on the grant date. ( 2 )At the end of Year 1, as to 50% of this PSU award (Part 1), the Compensation Committee of the Board of Directors determined, on September 15, 2023, that 101.8% of the performance conditions against the FY23 ARR targets were met resulting in an increase of 216 PSUs earned by the Reporting Person. 33% of Part 1 vested immediately thereafter. 33% of Part 1 will vest at the end of Year 2, and 33% of Part 1 will vest at the end of Year 3. At the end of Year 3, 50% of the PSU award (Part 2) will be determined based on performance against the FY25 ARR targets.
