Re: Confirmatory Employment Letter

Dear Shaun:

This confirmatory employment letter agreement (the “Agreement”) is entered into between Shaun Bagai (“you”) and RenovoRx, Inc. (the “Company” or “we”), effective as of November 11, 2021 (the “Effective Date”), to confirm the terms and conditions of your employment with the Company as of the Effective Date.

1. Title; Position; Location. You will continue to serve as the Company’s Chief Executive Officer. You also will continue to report to the Company’s Board of Directors (the “Board”) and will perform the duties and responsibilities customary for such position and such other related duties as are lawfully assigned by the Company’s Board. You will perform your duties from the Company’s corporate offices located in Los Altos, California (with the exception of any period during which a shelter-in-place order or similar work-from-home arrangement affecting your employment with the Company remains in effect), subject to customary travel as reasonably required by the Company and necessary to perform your job duties.

2. Best Efforts. You will continue to devote your full business time and best efforts to the faithful and loyal performance of your duties to the Company. While you render services to the Company, you will not engage in any other employment, consulting or other business activity (whether full-time or part-time) that would create a conflict of interest with the Company, and any engagement or participation in any outside business activity or business affairs by you will be subject to full disclosure and prior written approval from the Company’s Board or its Compensation Committee, as applicable. By signing this Agreement, you confirm that you have no contractual commitments or other legal obligations that would prohibit you from continuing to perform your duties for the Company.

3. Base Salary. As of the Effective Date, your annual base salary will be $363,000 (“Salary”), which will be payable, less any applicable withholdings, in accordance with the Company’s normal payroll practices. Your annual base salary will be subject to review and adjustment from time to time by our Board or its Compensation Committee, as applicable, in its sole discretion.

4. Annual Bonus. Commencing in the Company’s 2022 fiscal year, you will have the opportunity to earn a target annual cash bonus equal to fifty percent (50%) of your annual base salary earned during the fiscal year, based on achieving performance objectives established by the Board or its Compensation Committee, as applicable, in its sole discretion and payable upon achievement of those objectives, and subject to such terms and conditions, as determined by the Board or its Compensation Committee. Unless determined otherwise by the Board or its Compensation Committee, as applicable, any such bonus will be subject to your continued employment through and until the date of payment, and any such bonus amounts paid will be subject to any applicable withholdings. Your annual bonus opportunity and the applicable terms and conditions may be adjusted from time to time by the Board or its Compensation Committee, as applicable, in its sole discretion.

5. Equity Awards. You will be eligible to receive awards of stock options or other equity awards pursuant to any plans or arrangements the Company may have in effect from time to time. The Board or its Compensation Committee, as applicable, will determine in its sole discretion whether you will be granted any such equity awards and the terms of any such award in accordance with the terms of any applicable plan or arrangement that may be in effect from time to time.

6. Employee Benefits. You will continue to be eligible to participate in the benefit plans and programs established by the Company for its employees from time to time, subject to their applicable terms and conditions, including without limitation any eligibility requirements. The Company will reimburse you for reasonable travel or other expenses incurred by you in the furtherance of or in connection with the performance of your duties under this Agreement, pursuant to the terms of the Company’s expense reimbursement policy as may be in effect from time to time. The Company reserves the right to modify, amend, suspend or terminate the benefit plans, programs, and arrangements it offers to its employees at any time.

7. Severance. You will be eligible to enter into a Change in Control and Severance Agreement (the “Severance Agreement”) applicable to you based on your position within the Company. The Severance Agreement will specify the severance payments and benefits you may become entitled to receive in connection with certain qualifying terminations of your employment with the Company.

8. Confidentiality Agreement/Arbitration. As an employee of the Company, you will continue to have access to certain confidential information of the Company and you may, during the course of your employment, develop certain information or inventions that will be the property of the Company. To protect the interests of the Company, your acceptance of this Agreement confirms that the terms of the Company’s Employee Confidential Information and Invention Assignment Agreement you previously signed with the Company (the “Confidentiality Agreement”) still apply. Further, in the event of any dispute or claim relating to or arising out of our employment relationship, you and the Company agree that any and all disputes between you and the Company shall be fully and finally resolved by binding arbitration, subject to the terms and conditions of the arbitration agreement set forth in Appendix B.

9. At-Will Employment. This Agreement does not imply any right to your continued employment for any period with the Company or any parent, subsidiary, or affiliate of the Company. Your employment with the Company is and will continue to be at-will. Accordingly, you are free to resign at any time, for any reason or for no reason. Similarly, the Company is free to conclude its employment relationship with you at any time, with or without cause, and with or without notice. We request that, in the event of resignation, you give the Company at least two weeks’ notice.

10. Protected Activity Not Prohibited. The Company and you acknowledge and agree that nothing in this Agreement (or any other Company agreement or policy)limits or prohibits you from filing and/or pursuing a charge or complaint with, or otherwise communicating or cooperating with or participating in any investigation or proceeding that may be conducted by, any federal, state or local government agency or commission, including the Securities and Exchange Commission, the Equal Employment Opportunity Commission, the Occupational Safety and Health Administration, and the National Labor Relations Board (“Government Agencies”), including disclosing documents or other information as permitted by law, without giving notice to, or receiving authorization from, the Company. In addition, nothing in this Agreement (or any other Company agreement or policy) is intended to limit your rights to discuss the terms, wages, and working conditions of your employment, nor prevent you from discussing or disclosing information about unlawful acts in the workplace, such as harassment or discrimination or any other conduct that you have reason to believe is unlawful. You further understand that you are not permitted to disclose the Company’s attorney-client privileged communications or attorney work product. In addition, you acknowledge that the Company has provided you with notice in compliance with the Defend Trade Secrets Act of 2016 regarding immunity from liability for limited disclosures of trade secrets. The full text of the notice is attached in Appendix A.

11. Miscellaneous. This Agreement, together with the Confidentiality Agreement, the Severance Agreement and the stock options granted to you by the Company under its Amended and Restated 2013 Equity Incentive Plan and 2021 Omnibus Equity Incentive Plan and the applicable award agreements thereunder, constitute the entire agreement between you and the Company regarding the terms and conditions of your employment, and they supersede and replace all prior negotiations, representations or agreements between you and the Company. This Agreement will be governed by the laws of the State of California but without regard to the conflict of law provision, except that any dispute regarding the enforceability of the arbitration section set forth in Appendix B to this Agreement shall be governed by the Federal Arbitration Act. This Agreement may be modified only by a written agreement signed by a duly authorized officer of the Company (other than yourself) and you.

Appendix B

Arbitration and Equitable Relief

A. Arbitration. IN CONSIDERATION OF MY CONTINUED EMPLOYMENT WITH THE COMPANY, ITS PROMISE TO ARBITRATE ALL EMPLOYMENT-RELATED DISPUTES WITH ME, AND MY RECEIPT OF COMPENSATION AND OTHER COMPANY BENEFITS, AT PRESENT AND IN THE FUTURE, I AGREE THAT ANY AND ALL CONTROVERSIES, CLAIMS, OR DISPUTES THAT I MAY HAVE WITH THE COMPANY (INCLUDING ANY COMPANY EMPLOYEE, OFFICER, DIRECTOR, TRUSTEE, OR BENEFIT PLAN OF THE COMPANY, IN THEIR CAPACITY AS SUCH OR OTHERWISE), ARISING OUT OF, RELATING TO, OR RESULTING FROM MY EMPLOYMENT OR RELATIONSHIP WITH THE COMPANY OR THE TERMINATION OF MY EMPLOYMENT OR RELATIONSHIP WITH THE COMPANY, INCLUDING ANY BREACH OF THIS AGREEMENT, SHALL BE SUBJECT TO BINDING ARBITRATION PURSUANT TO THE FEDERAL ARBITRATION ACT (9 U.S.C. SEC. 1 ET SEQ.) (THE “FAA”). THE FAA’S SUBSTANTIVE AND PROCEDURAL PROVISIONS SHALL EXCLUSIVELY GOVERN AND APPLY WITH FULL FORCE AND EFFECT TO THIS ARBITRATION AGREEMENT, INCLUDING ITS ENFORCEMENT, AND ANY STATE COURT OF COMPETENT JURISDICTION SHALL COMPEL ARBITRATION IN THE SAME MANNER AS A FEDERAL COURT UNDER THE FAA. I FURTHER AGREE THAT, TO THE FULLEST EXTENT PERMITTED BY LAW, I MAY BRING ANY ARBITRATION PROCEEDING ONLY IN MY INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF, REPRESENTATIVE, OR CLASS MEMBER IN ANY PURPORTED CLASS, COLLECTIVE, OR REPRESENTATIVE LAWSUIT OR PROCEEDING. I UNDERSTAND, HOWEVER, THAT NOTHING IN THIS AGREEMENT PREVENTS ME FROM BRINGING A REPRESENTATIVE LAWSUIT OR PROCEEDING AS PERMITTED BY THE CALIFORNIA LABOR CODE’S PRIVATE ATTORNEYS GENERAL ACT OF 2004. TO THE FULLEST EXTENT PERMITTED BY LAW, I AGREE TO ARBITRATE ANY AND ALL COMMON LAW AND/OR STATUTORY CLAIMS UNDER LOCAL, STATE, OR FEDERAL LAW, INCLUDING, BUT NOT LIMITED TO, CLAIMS UNDER TITLE VII OF THE CIVIL RIGHTS ACT OF 1964, THE AMERICANS WITH DISABILITIES ACT OF 1990, THE AGE DISCRIMINATION IN EMPLOYMENT ACT OF 1967, THE OLDER WORKERS BENEFIT PROTECTION ACT, THE WORKER ADJUSTMENT AND RETRAINING NOTIFICATION ACT, THE FAIR LABOR STANDARDS ACT, THE CALIFORNIA FAIR EMPLOYMENT AND HOUSING ACT, THE FAMILY AND MEDICAL LEAVE ACT, THE CALIFORNIA FAMILY RIGHTS ACT, THE CALIFORNIA LABOR CODE, CLAIMS RELATING TO EMPLOYMENT STATUS, CLAIMS RELATING TO COMPENSATION (CASH, EQUITY, BONUS, OR OTHERWISE), CLAIMS RELATING TO CLASSIFICATION, AND CLAIMS OF HARASSMENT, DISCRIMINATION, WRONGFUL TERMINATION, AND BREACH OF CONTRACT. TO THE FULLEST EXTENT PERMITTED BY LAW, I ALSO AGREE TO ARBITRATE ANY AND ALL DISPUTES ARISING OUT OF OR RELATING TO THE INTERPRETATION OR APPLICATION OF THIS AGREEMENT TO ARBITRATE, BUT NOT DISPUTES ABOUT THE ENFORCEABILITY, REVOCABILITY, OR VALIDITY OF THIS AGREEMENT TO ARBITRATE OR THE CLASS, COLLECTIVE, AND REPRESENTATIVE PROCEEDING WAIVER HEREIN. WITH RESPECT TO ALL SUCH CLAIMS AND DISPUTES THAT I AGREE TO ARBITRATE, I HEREBY EXPRESSLY AGREE TO WAIVE, AND DO WAIVE, ANY RIGHT TO A TRIAL BY JURY. I FURTHER UNDERSTAND THAT THIS AGREEMENT TO ARBITRATE ALSO APPLIES TO ANY DISPUTES THAT THE COMPANY MAY HAVE WITH ME. I UNDERSTAND THAT NOTHING IN THIS AGREEMENT REQUIRES ME TO ARBITRATE CLAIMS THAT CANNOT BE ARBITRATED UNDER THE SARBANES-OXLEY ACT OR OTHER LAW THAT EXPRESSLY PROHIBITS ARBITRATION OF A CLAIM NOTWITHSTANDING THE APPLICATION OF THE FAA.

B. Administration of Arbitration. I AGREE THAT ANY ARBITRATION WILL BE ADMINISTERED BY JAMS PURSUANT TO ITS EMPLOYMENT ARBITRATION RULES & PROCEDURES (THE “JAMS RULES”), WHICH ARE AVAILABLE AT http://www.jamsadr.com/rules-employment-arbitration/. IF THE JAMS RULES CANNOT BE ENFORCED AS TO THE ARBITRATION, THEN THE PARTIES AGREE THAT THEY WILL ARBITRATE THIS DISPUTE UTILIZING JAMS COMPREHENSIVE ARBITRATION RULES AND PROCEDURES OR SUCH RULES AS THE ARBITRATOR MAY DEEM MOST APPROPRIATE FOR THE DISPUTE. I AGREE THAT THE ARBITRATOR SHALL HAVE THE POWER TO DECIDE ANY MOTIONS BROUGHT BY ANY PARTY TO THE ARBITRATION, INCLUDING MOTIONS FOR SUMMARY JUDGMENT AND/OR ADJUDICATION, AND MOTIONS TO DISMISS AND DEMURRERS, APPLYING THE STANDARDS SET FORTH FOR SUCH MOTIONS UNDER THE CALIFORNIA CODE OF CIVIL PROCEDURE. I AGREE that the arbitrator shall issue a written decision on the merits. I ALSO AGREE THAT THE ARBITRATOR SHALL HAVE THE POWER TO AWARD ANY REMEDIES AVAILABLE UNDER APPLICABLE LAW, AND THAT THE ARBITRATOR MAY AWARD ATTORNEYS’ FEES AND COSTS TO THE PREVAILING PARTY, WHERE PERMITTED BY APPLICABLE LAW. I agree that the decree or award rendered by the arbitrator may be entered as a final and binding judgment in any court having jurisdiction thereof. I UNDERSTAND THAT THE COMPANY WILL PAY FOR ANY ADMINISTRATIVE OR HEARING FEES CHARGED BY THE ARBITRATOR OR JAMS EXCEPT THAT I SHALL PAY ANY FILING FEES ASSOCIATED WITH ANY ARBITRATION THAT I INITIATE, BUT ONLY SO MUCH OF THE FILING FEES AS I WOULD HAVE INSTEAD PAID HAD I FILED A COMPLAINT IN A COURT OF LAW THAT WOULD HAVE HAD JURISDICTION OVER SUCH COMPLAINT. SUBJECT TO THE FAA’S EXCLUSIVE APPLICABILITY TO THE ENFORCEMENT OF THIS AGREEMENT TO ARBITRATE, I AGREE THAT THE ARBITRATOR SHALL ADMINISTER AND CONDUCT ANY ARBITRATION HEARING OR PROCEEDING APPLYING CALIFORNIA SUBSTANTIVE AND DECISIONAL LAW AND THE CALIFORNIA CODE OF CIVIL PROCEDURE, INCLUDING THE CALIFORNIA CIVIL DISCOVERY ACT. I agree that any arbitration under this Agreement shall be conducted in SANTA CLARA COUNTY, California.

C. Remedy. FOR PURPOSES OF SEEKING PROVISIONAL REMEDIES ONLY, I AGREE THAT THE COMPANY AND I SHALL BE ENTITLED TO PURSUE ANY PROVISIONAL REMEDY PERMITTED BY THE CALIFORNIA ARBITRATION ACT (CALIFORNIA CODE CIV. PROC. § 1281.8), OR OTHERWISE PROVIDED BY THIS AGREEMENT. EXCEPT FOR SUCH PROVISIONAL RELIEF, I AGREE THAT ANY RELIEF OTHERWISE AVAILABLE TO THE COMPANY OR ME UNDER APPLICABLE LAW SHALL BE PURSUED SOLELY AND EXCLUSIVELY IN ARBITRATION PURSUANT TO THE TERMS OF THIS AGREEMENT.

D. Administrative Relief. I UNDERSTAND THAT THIS AGREEMENT DOES NOT PROHIBIT ME FROM PURSUING AN ADMINISTRATIVE CLAIM WITH A LOCAL, STATE, OR FEDERAL ADMINISTRATIVE BODY OR GOVERNMENT AGENCY THAT IS AUTHORIZED TO ENFORCE OR ADMINISTER LAWS RELATED TO EMPLOYMENT, INCLUDING, BUT NOT LIMITED TO, THE DEPARTMENT OF FAIR EMPLOYMENT AND HOUSING, THE EQUAL EMPLOYMENT OPPORTUNITY COMMISSION, THE NATIONAL LABOR RELATIONS BOARD, THE SECURITIES AND EXCHANGE COMMISSION, OR THE WORKERS’ COMPENSATION BOARD. THIS AGREEMENT DOES, HOWEVER, PRECLUDE ME FROM PURSUING A COURT ACTION REGARDING ANY SUCH CLAIM, EXCEPT AS PERMITTED BY LAW.

E. Voluntary Nature of Agreement. I ACKNOWLEDGE AND AGREE THAT I AM EXECUTING THIS AGREEMENT TO ARBITRATE VOLUNTARILY AND WITHOUT ANY DURESS OR UNDUE INFLUENCE BY THE COMPANY OR ANYONE ELSE. I FURTHER ACKNOWLEDGE AND AGREE THAT I HAVE CAREFULLY READ THIS AGREEMENT TO ARTBIRATE AND THAT I HAVE ASKED ANY QUESTIONS NEEDED FOR ME TO UNDERSTAND THE TERMS, CONSEQUENCES, AND BINDING EFFECT OF THIS AGREEMENT TO ARBIBTRATE AND FULLY UNDERSTAND IT, INCLUDING THAT I AM WAIVING MY RIGHT TO A JURY TRIAL. I AGREE THAT I HAVE BEEN PROVIDED AN OPPORTUNITY TO SEEK THE ADVICE OF AN ATTORNEY OF MY CHOICE BEFORE SIGNING THIS AGREEMENT.

Agreed to and accepted:
