(the “Company”), a Delaware corporation, and Jeff Black (“Executive”). References below to the “Company” shall include its subsidiaries and affiliates when applicable.

1.Roles and Duties. Subject to the terms and conditions of this Agreement, the Company shall employ Executive as its Senior Vice President and Chief Financial Officer, reporting to the Company’s Chief Executive Officer (“CEO”). Executive shall have such duties and responsibilities as are reasonably determined by the CEO and are consistent with the duties customarily performed by Executive’s position in similarly situated companies. Executive accepts employment upon the terms and conditions set forth herein and agrees to perform such duties and discharge such responsibilities to the best of Executive’s ability. Executive shall devote all of Executive’s business time and energies to the business and affairs of the Company. Notwithstanding the foregoing, nothing herein shall preclude Executive from (i) serving on boards, committees or similar bodies of charitable or nonprofit organizations; (ii) fulfilling limited teaching, speaking and writing engagements; and (iii) managing Executive’s personal investments and affairs; provided, however, that the activities set out in clauses (i)-(iii) shall be limited by Executive to not materially conflicting with the performance of Executive’s duties and responsibilities to the Company or contravene any restrictive covenants or codes of conduct; provided, that with respect to the activities in clauses (ii) and/or (iii), Executive shall notify the Board of such activities.

2.Term of Employment. Executive’s employment hereunder shall commence on the Effective Date and shall continue until terminated hereunder by either party (such term of employment shall be referred to herein as the “Term”), which termination shall be effectuated on no less than thirty (30) days’ written notice to each other (except in the case of Executive’s death).

3.Compensation.

(a)Base Salary. The Company shall pay Executive a base salary (the “Base Salary”) at the annual rate of Four Hundred and Sixty Thousand Dollars ($460,000). The Base Salary shall be payable in substantially equal periodic installments in accordance with the Company’s payroll practices as in effect from time to time. The Company shall deduct from each such installment all amounts required to be deducted or withheld under applicable law or under any employee benefit plan in which Executive participates.

(b)Signing Bonus. You will receive a signing bonus of One Hundred and Twenty-Five Thousand Dollars ($125,000) subject to applicable taxes and withholding, which will be payable no later than thirty (30) days from the Effective Date (the "Signing Bonus"). Upon your resignation without Good Reason or the Company's termination of your employment for Cause (as such terms are defined in the Company’s Amended and Restated Executive Change in Control and Severance Plan (the “Severance Plan”)), in either case occurring within one (1) year of the Effective Date, you shall be required to repay the Signing Bonus in full (gross of taxes) to the Company no later than thirty (30) days after the date of such termination or resignation. If you are

subject to an Involuntary Termination within one (1) year of the Effective Date, the Signing Bonus shall not be repayable to the Company.

(c)Annual Performance Bonus. Executive shall be eligible to receive an annual cash bonus (the “Annual Performance Bonus”) pursuant to the Company’s bonus plan offered to Company executives, with a target equal to 50% of Executive’s then-current Base Salary. The Annual Performance Bonus will be pro-rated for the year 2024. The Annual Performance Bonus will be based on achieving annual performance metrics determined by the Compensation Committee (or the Board) in its sole discretion.

Nothing contained herein shall create or be deemed to create any obligation on the part of the Company to adopt or maintain any health, welfare, retirement or other benefit plan or program at any time or to create any limitation on the Company’s ability to modify or terminate any such plan or program.

(g)Reimbursement of Expenses. The Company shall reimburse Executive for all ordinary and reasonable out-of-pocket business expenses incurred by Executive in furtherance of the Company’s business in accordance with the Company’s policies with respect thereto as in effect from time to time.
