NOW, THEREFORE, the parties intending to be legally bound, mutually agree as follows: 1.

(b) In accordance with Section 7(g) of the Employment Agreement, effective January 31, 2024, Executive xxxxxx resigns from all positions held by Executive with the Company and its affiliates. Executive agrees to execute letters of resignation and/or other documents as may be required or requested by the Company and otherwise cooperate fully and take all steps reasonable and necessary to effectuate or evidence the resignation(s) set forth in this Section. (c) As of the Separation Date, Executive shall not be eligible to participate in, or be covered by, any employee benefit plan or program offered by or through the Company, and Executive shall not receive any benefits or payments from the Company, except as otherwise provided in this Agreement, under the terms of applicable benefits plans, or by law. (d) Without regard to whether Executive signs this Agreement, Executive will:

2 (i) be paid any base salary that is accrued but unpaid as of the Separation Date on the first business day after the Separation Date; and (ii) in accordance with Section 7(e) of the Employment Agreement, receive (i) a pro rata base salary payment in the amount of Forty-Two Thousand Three Hundred Three Dollars and Fifty-Seven Cents ($42,303.57), less applicable taxes and withholding deductions, (ii) a one-time contribution in the amount of One Thousand Two Hundred Sixty-Nine Dollars and Ten Cents ($1,269.10) to Executive’s 401K (Safe Harbor) account, all of which is equivalent to Executive’s base salary plus eligible benefits, from February 1, 2024, through March 17, 2024 (the “Remainder Notice Period”), payable on the first business day after the Separation Date; and (iii) continue to be covered through January 31, 2024, under the Company’s group health, dental and vision insurance plans (collectively, the “Health Insurance Plans”) with the same coverage, deductibles and other plan conditions as existed on the Separation Date.
