        <footnote id="F1">Represents stock options granted to the Reporting Person as compensation in connection with his appointment as Interim Chief Executive Officer of 374Water Inc. (the &quot;Company&quot;). The vesting commencement date of the stock options is October 7, 2025. 25% of the stock options vest and become exercisable on the vesting commencement date, 25% of the stock options vest and become exercisable 90 days after the vesting commencement date, 25% of the stock options vest and become exercisable 180 days after the vesting commencement date and 25% of the stock options vest and become exercisable 270 days after the vesting commencement date, subject to the Reporting Person's continuing service through each vesting date. (Continues in footnote no. 2)</footnote>
        <footnote id="F2">Notwithstanding the foregoing, the stock options will vest and become exercisable immediately in the event of (i) a change of control of the Company, (ii) the hiring of a full-time Chief Executive Officer for the Company, or (iii) the termination of the Reporting Person other than for cause. Upon vesting, each stock option gives the Reporting Person the right to purchase one share of the Company's Common Stock at the exercise price. The stock options expire on the date which is ten years from the date on which the applicable shares vest, unless earlier terminated in accordance with the stock option grant agreement.</footnote>
