(the “Company”) concerning the terms of your transition from your role as its Chief Legal Officer to your role as a Senior Advisor to the Company. Defined terms used herein but not otherwise defined shall have the same meaning as set forth in either the offer letter agreement that you entered into with the Company dated May 5, 2021 or the Change In Control & Severance Agreement that you entered into with the Company, dated February 23, 2022, attached hereto as Exhibits A and B (the “Employment Agreements”). 1. Transition. March 8, 2024, will be your last day of employment with the Company (the “Last Date of Employment”) as its Chief Legal Officer and you will immediately begin your role as a Senior Advisor to the Company’s CEO on the Last Date of Employment. You will serve in such role as an independent contractor to the Company. For the avoidance of doubt, your transition from an employee to an advisor to the Company as described above will not be deemed to interrupt or terminate your Continuous Service to the Company (as defined in the Company’s 2021 Equity Incentive Plan) and, accordingly, your unvested shares under your RSU Agreements (as defined below) will continue to vest in accordance with the terms of paragraph 4 below during the term of your Advisory Services Agreement (as defined below) or during your provision of Continuous Service to Company in another qualifying capacity. 1. 2. Senior Advisor Role. Under the Senior Advisor role you will provide strategic advice as and when requested by the Company’s CEO and/or General Counsel from time to time on matters affecting the Company's business, operations, projects, and initiatives. The initial term of that relationship will be twelve (12) months from the date of this Agreement and it shall renew for subsequent twelve (12) month terms unless either party provides the other party notice of its intent not to renew at least thirty (30) days prior to the beginning of the next renewal term. During the term of your advisory role, you shall be paid $10,000 per month as compensation. Attached as Exhibit C is the Statement of Work that will be executed concurrently with this Agreement and will govern your provision of such services. The Statement of Work, together with the Archer General Supplier Terms & Conditions referenced in Exhibit C, shall be referred to herein as the “Advisory Services Agreement”. 2. 3. Benefits: In exchange for your agreement to the general release and waiver of claims set forth below and your other promises herein, the Company agrees to provide you with the following transition benefits to be paid, and/or effective, within ten (10) days of the Last Date of Employment: Doc ID: ab77cbe79b3bff24d239253ac77205618019499c EXHIBITS A-C TO THIS EXHIBIT HAVE BEEN OMITTED PURSUANT TO ITEM 601(A)(5) OF REGULATION S-K.

(c) $35,811, which is the amount of your COBRA premiums for twelve (12) months; and 6. (d) 340,498 of your Unvested RSUs shall accelerate and become fully vested as of the Last Date of Employment. 7. By signing below, you acknowledge that you are receiving these benefits in exchange for waiving your rights to claims referred to in this Agreement, and that the benefits fully satisfy all severance and other separation benefit obligations (including, without limitation, accelerated vesting) for which you are or could be eligible pursuant to the Employment Agreements or otherwise. Before taking out any withholding for taxes for any payments described herein, or reporting to the relevant tax authorities, the Company will notify you of the amounts it intends to withhold, and provide you with a reasonable opportunity to provide prompt input on the Company’s calculations; provided, however, that the final determination shall be within the Company’s sole discretion after good faith consideration of your input. 4. RSU Holdings; Continued Vesting. During your employment at the Company, you were issued 1,361,991 restricted stock units (“RSUs”) subject to time based vesting as set forth in the underlying RSU Award Grant Notices and RSU Award Agreements (the “RSU Agreements”). As of your Last Date of Employment, 646,494 of those RSUs will remain unvested (the “Unvested RSUs”), subject to the next sentence. Following the accelerated vesting of 340,498 RSUs on the Last Date of Employment as described above, 305,996 of those RSUs will remain unvested (the “Remaining RSUs”). Subject to your Continuous Service as a Senior Advisor to our CEO or your Continuous Service to the Company in some other qualifying capacity (e.g., board member, employee, etc.) those Remaining RSUs shall continue to vest as follows: Vesting Date Number of Shares To Vest May 15, 2024 62,500 May 15, 2024 22,624 August 15, 2024 62,500 August 15, 2024 22,625 November 15, 2024 22,624 March 1, 2025 22,625 Doc ID: ab77cbe79b3bff24d239253ac77205618019499c
