On May 16, 2024 (the "Effective Date"), 374Water Inc.

Mr. Meyers is also eligible to earn an annual fiscal year performance bonus with a target amount equal to 50% of Mr. Meyers' then base-salary (the "Annual Bonus").

Under the Employment Agreement and subject to the terms of the Company's 2021 Equity Incentive Plan (the "Plan"), Mr. Meyers is eligible to receive up to 231,000 Restricted Stock (as defined in the Plan) and 231,000 Options (as defined in the Plan, and collectively, the "Meyers Equity Awards"), vesting as follows: (a) with respect to 115,500 Restricted Stock and 115,500 Options, 25% shall vest on the first anniversary of the Effective Date, and the remaining 75% shall vest in equal increments over the following 36 months; and (b) with respect to the remaining 115,500 Restricted Stock and 115,000 Options, each shall vest in accordance with the Company milestones set forth in Exhibit A of the Employment Agreement. The per share exercise price of the Options will be the Fair Market Value (as defined in the Plan).

If the Employment Agreement is terminated by the Company without “Cause” or by Mr. Meyers for “Good Reason” (each as defined in the Employment Agreement, subject to the Company’s right to cure), he will be entitled to termination benefits, pursuant to which the Company will be obligated to (i) pay Mr. Meyers six months of his then-current annual base salary in six equal installments; (ii) any earned but unpaid Annual Bonus; (iii) coverage to Mr. Meyers and his dependents under the Company’s then current medical, health, and vision insurance plans for six months; and (iv) if such separation occurs on the day of Mr. Meyers’s first year anniversary of employment or after the first anniversary of the Effective Date, (x) a pro-rated Annual Bonus for the fiscal year in which the employment is terminated equal to the pro-rated Annual Bonus that Mr. Meyers would have received based on actual performance for such fiscal year if Mr. Meyers was employed by the Company, and (y) accelerated vesting with respect to the Meyers Equity Awards as if Mr. Meyers had remained employed by the Company through the six-month anniversary of the date of such separation.

The Employment Agreement contains covenants for the benefit of the Company relating to protection of the Company’s confidential information and standard Company indemnification obligations.

The foregoing description of the Employment Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of such agreement, which is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.

The shares of the Company’s common stock and the Company’s common stock underlying the Meyers Equity Awards may be issued, if any, in a private placement transaction that will rely upon an exemption from registration provided by Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”), and/or Regulation D promulgated thereunder, or pursuant to the Company’s Registration Statement on Form S-8, if and when such is filed by the Company with the U.S. Securities and Exchange Commission.

(b) Outside Activities. During the Employment Period, the Executive will be expected to devote Executive’s full working time and attention to the business of the Company, and Executive will not render services to any other business without the prior approval of the CEO. Notwithstanding the foregoing, Executive may manage personal investments, participate in civic, charitable, and academic activities (if in a limited, non-leadership capacity unless a larger role is approved by the CEO), and, subject to prior approval by the CEO, serve on the board of directors (and any committees) and/or as an advisor of other for-profit companies, provided that such activities do not at the time the activity or activities commence or thereafter (a) create an actual or potential business or fiduciary conflict of interest or (b) individually or in the aggregate, interfere materially with the performance of Executive’s duties to the Company.

(c) Additional Conditions. In addition, the Executive shall act in accordance with (i) standing instructions for the position which may be issued by the CEO from time to time; (ii) all reasonable and lawful requests, directions and/or restrictions imposed by the CEO; and (iii) all policies of the Company as prescribed from time to time.

The Executive’s employment by the Company shall continue until this Agreement and the Executive’s employment are terminated pursuant to Section 7 below (the “Employment Period”). For all purposes of the Agreement, no termination of the Executive’s employment shall be deemed to have occurred if the Executive is transferred during the Employment Period to any business entity which is an Affiliate of the Company. As used in this Agreement, the term “Affiliate” means, with respect to any specified person or entity (“Person”), any other Person that, directly or indirectly through one or more intermediaries, controls, is controlled by, or is under common control with, such specified Person.

Thereafter, Executive’s Base Salary shall be periodically reviewed as a part of the Company’s regular review of compensation, and will be determined by the Compensation Committee (the “Compensation Committee”) of the Board of Directors (the “Board”). Any increased base salary shall thereafter constitute the Base Salary for purposes hereof.

(b) Target Bonus. Executive will be eligible for an annual bonus (the “Annual Bonus”) with a target amount equal to 50% of Executive’s then-current annual Base Salary. The Annual Bonus objectives and performance criteria shall be determined in consultation between Executive and the CEO on an annual basis.

7. Termination. Executive's employment may be terminated in any one of the following ways:

3

In the event of a termination for Cause, as enumerated above, Executive shall have no right to any Separation Benefits (as defined in Subsection 6(e) below) or other compensation accruing after the effective date of termination (the “Separation Date”), and no right to bonus not yet due and payable at the time of termination.

(d) Termination Without Cause. At any time after the Effective Date, the Company may terminate the Executive’s employment without Cause.

All other rights and obligations of the Company and Executive under this Agreement shall cease as of the Separation Date, except as otherwise provided in the Confidentiality Agreement (as defined in Section 12 of this Agreement) or any termination notice or separation and release agreement between the Executive and the Company.

4

(c) Separation Benefits. In the event the Company terminates Executive’s employment without Cause or Executive resigns for Good Reason, the Company shall, subject to the provisions of Subsection 8(d), provide Executive with the following benefits:

(i) the Company shall pay an amount equal to six (6) months of Executive’s then-current Base Salary, which shall be paid out in substantially equal installments in accordance with the Company’s payroll practice, as in effect at the time of Executive’s termination, over a six (6) month period following the Separation Date;

(ii) the Company will provide substantially similar coverage under the Company’s then current medical, health, and vision insurance plans to Executive and his eligible dependents for a period of six (6) months provided that Executive continues to make any required employee contribution;

(iii) any earned but unpaid Annual Bonus with respect to any completed performance period or milestone; and

(iv) if such separation occurs on the day of Executive’s first year anniversary of employment or after the first anniversary of the Effective Date, (x) a pro-rated Annual Bonus for the fiscal year in which the employment is terminated equal to the pro-rated Annual Bonus that Executive would have received based on actual performance for such fiscal year if Executive had remained in the employ of the Company, to be paid at the same time annual bonuses are paid by the Company to other executives of the Company for the fiscal year in which Executive’s employment terminated, but no later than March 15^th of the calendar year following the calendar year in which Executive terminated employment, and (y) accelerated vesting with respect to the Executive Awards as if Executive had remained in the employ of the Company through the six month anniversary of the Separation Date.
