Dear Bill:

This letter confirms the agreement (“Agreement”) between you and Energous Corporation (the “Company”) concerning the terms of your transition and separation from employment and offers you certain benefits to which you would not otherwise be entitled, conditioned upon your provision of a general release of claims and covenant not to sue now and upon the Separation Date (defined below) as provided herein. If you agree to the terms outlined herein, please sign and return this Agreement to me in the timeframe outlined below.

1. Continued Employment; Other Release Consideration: In exchange for your agreement to the general release and waiver of claims and covenant not to sue set forth below and your other promises herein, the Company agrees to continue your employment on the following terms:

a. Separation Date; Transition Period and Services: Your last day of employment with the Company will be August 16, 2023 (the “Separation Date”). Between now and the Separation Date (the “Transition Period”), you agree to carry out the duties and responsibilities of your position as directed principally by the Company’s executive leadership, including its interim CFO, and to provide other transition services as may reasonably be requested by the Company, including, without limitation, (i) transition of the responsibilities, duties, and knowledge relative to your position, and (ii) if requested by the Company, execution of the Company’s August 2023 10-Q financial statement, providing you shall not be required to sign the 2023 10-Q unless you believe the 10-Q and the required attestations are accurate (the “Transition Services”). During the Transition Period, you will primarily work remotely and come into the Company’s San Jose, California headquarters only when and as requested by the new interim CFO. By signing below, you hereby resign, effective as of the Separation Date, from all officer positions of the Company that you may hold, including, without limitation, the position of Acting Chief Financial Officer of the Company.

c. Separation Compensation: Provided that you adequately provide the Transition Services, then in exchange for your agreement to the general release and waiver of claims and covenant not to sue in this Agreement and as set forth in Exhibit A (the “Second Release”), to be signed no earlier than the Separation Date, and your other promises herein, the Company agrees as follows:

i. Severance: The Company agrees to pay you, in regular bi-weekly installments consistent with the Company’s regular payroll schedule, your regular base salary (as of the Separation Date, which base salary shall not be reduced from the base salary you are receiving on the date you sign this Agreement) for nine (9) months following the Separation Date. The first severance payment will commence on the Company’s first regularly payroll schedule following the Effective Date of the Second Release (as provided therein) (the “First Severance Payment”), provided that, the First Severance Payment shall include any amounts that would otherwise have been payable to you during such time period between the Separation Date and First Severance Payment.

ii. COBRA: Upon your timely election to continue your existing health benefits under COBRA, and consistent with the terms of COBRA and the Company’s health insurance plan, the Company will pay the insurance premiums to continue your existing health benefits for nine (9) months following the Separation Date. You will remain responsible for, and must continue to pay, the portion of premiums, co-payments, etc. that you would have paid had your employment continued.

iii. Restricted Stock Unit Vesting Credit: The Company will provide, and you will receive, additional restricted stock unit vesting credit, as described in Paragraph 5, below.

iv. Reimbursement of Attorneys’ Fees: The Company will reimburse you up to Twenty-Five Thousand Dollars ($25,000) for reasonable legal fees incurred by you directly in connection with the negotiation and execution of this Agreement, through a payment to the Law Offices of Jotham S.

You agree to submit no later than ten (10) business days following the Effective Date of the Second Release (as defined therein) reasonable written proof of having incurred such fees, and the Company shall issue payment to Stein for such documented legal fees no later than ten (10) business days following receipt of such documentation.

Protected Rights: You understand that nothing in the General Release and Waiver of Claims and Covenant Not to Sue paragraphs above, or otherwise in this Agreement, limits your ability to file a charge or complaint with the Equal Employment Opportunity Commission, the National Labor Relations Board, the Occupational Safety and Health Administration, the Securities and Exchange Commission or any other federal, state or local government agency or commission (“Government Agencies”). You further understand that this Agreement does not limit your ability to communicate with any Government Agencies or otherwise participate in any investigation or proceeding that may be conducted by any Government Agency, including providing documents or other information, without notice to the Company. This Agreement does not limit your right to receive an award for information provided to any Government Agencies.

This Agreement shall be afforded the maximum protection allowable under California Evidence Code Section 1152 and/or any other state or federal provisions of similar effect.

12. Complete and Voluntary Agreement: This Agreement, together with Exhibits A and B hereto and the Restricted Stock Unit Agreements, constitute the entire agreement between you and Releasees with respect to the subject matter hereof and supersedes all prior negotiations and agreements, whether written or oral, relating to such subject matter.
