        <footnote id="F2">Performance-Based Restricted Stock Units were previously reported on September 25, 2020, 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 July 20, 2020 and July 20, 2024. The achievement date occurred on January 28, 2021, as certified by the compensation committee of ATEN on February 2, 2021, resulting in 3,250 units meeting the appropriate performance-based conditions. These shares will therefore vest as to one-half within thirty (30) days of the date of achievement of the milestone with an additional one-fourth on each of the first and second anniversaries of achievement of the milestone, subject to continued employment.

Upon achievement of a Performance Milestone, vesting is subject to continued employment with the Company through the applicable vesting date, which occurs in three equal installments with the first vesting to occur within thirty (30) days of achievement of the Performance Milestone and an additional one-third (1/3) on each of the first and second anniversaries of the date of achievement of the corresponding Performance Milestone.</footnote>
