        <footnote id="F1">Each restricted stock unit represents a contingent right to receive one share of OSPN common stock.</footnote>
        <footnote id="F2">On August 5, 2022, the reporting person was granted performance stock units (PSUs) that were eligible to be earned based upon the registrant's achievement of specified financial metrics for 2022. On February 23, 2023, the registrant's Compensation Committee determined that the  reporting person had earned 39,200 PSUs based upon the 2022 financial metrics. The earned PSUs will vest on December 31, 2024, assuming the reporting person continues to be employed by the registrant on that date.</footnote>
        <footnote id="F3">The restricted stock units vest over three years starting on February 23, 2023, with one-third of the shares vesting on February 23, 2024 and one-sixth of the shares vesting every six months thereafter.</footnote>
