        <footnote id="F4">On March 30, 2023 (the &quot;Grant Date&quot;), the Issuer granted Mr. Senkypl nonqualified stock options (the &quot;Stock Options&quot;) to purchase shares of Common Stock at a per share exercise price of $6.00 under the Issuer's 2011 Incentive Plan, as amended (the &quot;Plan&quot;). A majority vote of the Issuer's stockholders subsequently approved an amendment to the Plan at the Issuer's 2023 Annual Meeting of Stockholders, pursuant to which the Stock Options would vest and be exercised prior to the first anniversary of the Grant Date. Accordingly, one eighth (1/8th) of the Stock Options vested on June 30, 2023 and the remainder vested in substantially equal quarterly installments over the next seven (7) quarters. As of December 31, 2025, all 3,062,500 options were fully vested.</footnote>
        <footnote id="F5">The Stock Options have a contractual expiration date of March 30, 2026. Pursuant to the terms of the
Plan, if the expiration date of an option falls during a blackout period, the expiration date is automatically extended until 30 calendar days after the end of such blackout period. As the contractual expiration date of March 30, 2026 fell during a blackout period, the Stock Options remained exercisable until June 15, 2026.</footnote>
