Separation Agreement between SenesTech, Inc. and Nicole Williams dated April 21, 2023

1.End of Employment The Company has decided to end your employment due to missing revenue targets in 2022 and in the first quarter of 2023. Your performance has consistently fallen short of expectations resulting in significant losses in revenue for the company. This constitutes “Cause” as set forth in the Company’s letter agreement with you dated May 1, 2021. Notwithstanding the existence of Cause, the Company is willing to treat the termination of your employment as a termination without Cause provided that you enter into this Agreement. Effective April 20, 2023 (the "Effective Date"), Nicole Williams (the “Employee”), agrees that Employee's employment with the Company is hereby terminated, and Employee further resigns from all positions held by the Employee with the Company, effective as of the Effective Date. Your last day will be April 20, 2023.

2.Continuation of Salary and Benefits.

2.1.Accrued Salary and Paid Time Off. On the next regular payroll date following the Effective Date, the Company will pay the Employee all accrued and unused vacation along with outstanding personal pay accumulated in the field, subject to standard payroll deductions and withholdings. The Employee is entitled to these payments by law.

2.2.Severance. Although the Company has no obligation to do so, if the Employee signs this Agreement, allows it to become effective, and complies with the obligations under this Agreement, then the Company will pay the Employee a severance (the “Severance”) equal to six (6) months from the Effective Date.

Payment shall be an amount equal to Employee's rate of pay on the Effective Date, after the Employee’s acceptance of and compliance with this Agreement and the expiration of the rescission period, subject to standard payroll deductions and withholdings. This offer will remain open for twenty-one (21) days.

2.3.Health Insurance. On the Effective Date and through the Severance period, to the extent provided by the federal COBRA law or, if applicable, state insurance laws, and by the Company’s current group health insurance policies, the Employee will be eligible to continue their group health insurance benefits at their own expense following the Effective Date. The Company will continue to pay Employee contributions of the Employee’s group health insurance (if applicable) for up to six (6) emonths after the Effective Date. Later, the Employee may be able to convert to an individual policy through the provider of the Company’s health insurance, if the Employee wishes. The Employee will be provided with a separate notice describing their rights and obligations under COBRA.

2.4.Stock Options. Upon termination of an Employee’s employment, below are the choices for exercising any stock options the Employee holds with SenesTech, Inc. 

3.3 Termination of Eligibility: Any option granted hereunder shall expire if, for any reason other than his or her death, the optionee ceases to be an Employee of the Corporation or a Parent or Subsidiary thereof.  The expiration will take effect at the earliest of the following times: three (3) months from the date of the occurrence causing termination of eligibility (twelve (12) months if the optionee's eligibility ceases because of his or her disability), provided the optionee retains his or her status as an Employee as defined herein, or upon the date the option expires by its terms. During such four-month period, the option may be exercised in accordance with its terms, but only in respect of the number of shares for which the right to exercise has accrued on the date of termination of employment, or status as a director or independent contractor. The Committee shall decide whether an authorized leave of absence or absence for military or governmental service, or absence for any other reason, shall constitute termination of eligibility for purposes of this Section. This determination shall be subject to review by the Board of Directors.

2.5Other Compensation or Benefits. The Employee acknowledges that, except as expressly provided in this Agreement, they have not earned and will not receive from the Company any additional compensation (including base salary, bonus, incentive compensation, or equity), severance, or benefits before or after the Effective Date with the exception of any vested right they may have under the express terms of a written ERISA-qualified benefit plan (e.g., 401(k) account) or any vested options.

2.6Expense Reimbursements. The Employee agrees that, within ten (10) days of the Effective Date, the Employee will submit their final documented expense reimbursement statement reflecting all business expenses incurred through the Effective Date, if any, for which the Employee requests reimbursement. The Company will reimburse the Employee for these expenses pursuant to its regular business practice.

3.Return of Company Property. The Employee agrees to return to the Company all Company documents, passwords (and all copies thereof) and other Company property which the Employee has in their possession or control, including, but not limited to, Company files, notes, drawings, records, plans, forecasts, reports, studies, analyses, proposals, agreements, financial information, research and development information, sales and marketing information, customer lists, prospect information, pipeline reports, sales reports, operational and personnel information, specifications, code, software, databases, computer-recorded information, tangible property and equipment (including, but not limited to, computers, facsimile machines, mobile telephones, servers), credit cards, entry cards, identification badges and keys; and any materials of any kind which contain or embody any proprietary or confidential information of the Company (and all reproductions thereof in whole or in part). The Employee agrees that they will make a diligent search to locate any such documents, property, and information by the close of business on the Effective Date. If the Employee has used any personally owned computer, server, or e-mail system to receive, store, review, prepare or transmit any Company confidential or proprietary data, materials or information, within fifteen (15) business days after the Effective Date, they shall provide the Company with a computer-useable copy of such information and then permanently delete and expunge such Company confidential or proprietary information from those systems; and the Employee agrees to provide the Company access to their system as requested to verify that the necessary copying and/or

deletion is done. The Employee’s timely compliance with this paragraph is a condition precedent to their receipt of the severance benefits provided under this Agreement.

4.Confidentiality. The provisions of this Agreement will be held in strictest confidence by The Employee and will not be publicized or disclosed by the Employee in any manner whatsoever; provided, however, that: (a) the Employee may disclose this Agreement in confidence to your immediate family and to your attorneys, accountants, tax preparers and financial advisors; and (b) the Employee may disclose this Agreement insofar as such disclosure may be necessary to enforce its terms or as otherwise required by law. In particular, and without limitation, the Employee agrees not to disclose the terms of this Agreement to any current or former Company employee.

5.Non-disparagement. The Employee agrees not to disparage the Company, its officers, directors, employees, shareholders, and agents, in any manner likely to be harmful to its or their/its business, business reputation, or personal reputation; provided that the employee will respond accurately and fully to any question, inquiry or request for information when required by legal process.

6.No Admissions. The Employee understands and agrees that the promises and payments in consideration of this Agreement shall not be construed to be an admission of any liability or obligation by the Company to the Employee or to any other person, and that the Company makes no such admission.

7.Release of Claims. In exchange for the consideration under this Agreement to which the Employee would not otherwise be entitled, the Employee hereby generally and completely releases the Company and its executives, directors, officers, employees, shareholders, partners, agents, attorneys, predecessors, successors, parent and subsidiary entities, insurers, affiliates, and assigns from any and all claims, liabilities and obligations, both known and unknown, that arise out of or are in any way related to events, acts, conduct, or omissions occurring at any time prior to and including the date the Employee signs this Agreement.

Notwithstanding the foregoing, the Employee is not releasing the Company hereby from any obligation to indemnify the Employee pursuant to the Articles and Bylaws of the Company, any valid fully executed indemnification agreement with the Company, applicable law, or applicable directors and officer’s liability insurance. Also, excluded from this Agreement are any claims that cannot be waived by law. The Employee is waiving, however, the right to any monetary recovery should any governmental agency or entity, such as the Equal Employment Opportunity Commission or the Department of Labor, pursue any claims on their behalf. The Employee represent that they have no lawsuits, claims or actions pending in their name, or on behalf of any other person or entity, against the Company or any other person or entity subject to the release granted in this paragraph.

8.ADEA Release.

period has expired, which will be the eighth day after the date that this Agreement is signed by you provided that you do not revoke it (the “Effective Date”).

9.Representations. The Employee hereby represent that they will be paid all compensation owed by the Effective Date and for all hours worked, have received all the leave, and leave benefits and protections for which they are eligible or otherwise, and have not suffered any on-the-job injury for which they have not already filed a workers’ compensation claim.

This Agreement will bind the heirs, personal representatives, successors and assigns of both the Employee and the Company and inure to the benefit of both the Employee and the Company, their heirs, successors, and assigns. If any provision of this Agreement is determined to be invalid or unenforceable, in whole or in part, this determination will not affect any other provision of this Agreement and the provision in question will be modified to be rendered enforceable.
