Footnotes

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) day trading period between February 2, 2021 and February 2, 2025. The achievement of the first milestone occurred on July 30, 2021, as certified by the compensation committee August 2, 2021, resulting in 9,314 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 August 9, 2021 and an additional one-third (1/3) on each of the first and second anniversaries of July 30, 2021, subject to continued employment. These shares are reflected on Table I.
