Explanation of Responses:

Id Content
F1 Performance-Based Restricted Stock Units were previously reported on February 4, 2021, each of which represents a contingent right to receive one share of common stock of ATEN, with vesting subject to the achievement of specified levels of the volume weighted average closing prices of a share of ATEN common stock during any one hundred (100) calendar day trading period between February 2, 2021 and February 2, 2025. The last milestone achievement date occurred on September 2, 2021, as certified by the compensation committee of ATEN on September 11, 2021, resulting in 39,588 units meeting the appropriate performance-based conditions. However, these shares remain subject to time-based vesting conditions and will therefore vest as to one-third (1/3) on September 16, 2021 and an additional one-third (1/3) on each of the first and second anniversaries of September 2, 2021, subject to continued employment. These shares are reflected on Table I.
