### Footnotes:

(1) Each restricted stock unit represents a contingent right to receive one share of OSPN common stock.

(2) The restricted stock units vest over three years starting on March 4, 2025, with one-third of the shares vesting on March 4, 2026 and one-sixth of the shares vesting every six months thereafter.

(3) On March 4, 2025, 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 2025. On February 17, 2026, the registrant's Compensation Committee determined that the reporting person had earned 42,511 PSUs based on the 2025 financial metrics. The earned PSUs vested as to 1/3 of the shares on March 4, 2026 and will vest as to an additional 1/3 of the shares on each of December 31, 2026 and December 31, 2027, assuming the reporting person continues to be employed by the registrant on the applicable vesting date.
