Amendment to Director Compensation Plan

On January 28, 2026, our Board of Directors adopted a revised Non-Employee Director Compensation Program and Stock Ownership Guidelines (the “Director Compensation Plan”) in order to allow discretion to the Board in the number of options to be granted to each non-employee director in connection with the Company’s annual grant of stock options, and in the form and amount of the initial equity grant to new directors. A copy of the Director Compensation Plan is filed herewith as Exhibit 10.2.

Appointment of Director

Effective January 28, 2026, our Board appointed Ms. Vanessa Jacoby as a director of our Company. She will replace Dr. Birnbaum as an independent director. Ms. Jacoby was also appointed as Chairperson of our Audit Committee and as a non-chairperson member of our Compensation Committee. We look forward to working with Ms. Jacoby, who brings extensive experience in the biotechnology and life science sectors, having served as a senior financial executive of several private and public companies and has been an active participant on audit committees, responsible for reporting financial results, cyber security matters, Sarbanes Oxley internal controls and other matters, as well as on compensation committees.

Ms. Jacoby currently serves as the Chief Business and Financial Officer for Quanta Therapeutics, Inc., a clinical stage biotechnology company focused on developing best-in-class small molecules inhibitors for RAS-driven cancers. Prior to joining Quanta, Ms. Jacoby served as Chief Financial Officer of Shoreline Biosciences. Prior to joining Shoreline, Ms. Jacoby served as Chief Accounting Officer of Avidity Biosciences, Inc. Prior to Avidity, Ms. Jacoby was Vice President, Finance at PharmAkea, which was acquired by Galecto in 2019. Prior to that, she served as Director of Accounting and Controller at BCI, Inc., and held senior financial roles at Artes Medical and Verenium Corporation. Before joining industry, Ms. Jacoby was an auditor for Ernst & Young. Ms. Jacoby received her M.B.A. from National University and B.S. degree in Business Administration from Fundação Armando Alvares Penteado, Sao Paulo, Brazil. She is a Certified Public Accountant with the State of California (inactive). She currently serves on the board of trustees for the Ruben H. Fleet Science Center in San Diego and is on the board for the Association of Bioscience Financial Officers (ABFO) Southwest chapter.

She will also receive an additional $10,000 annually as Chair of the Audit Committee and $7,500 as a non-chairperson member of the Compensation Committee. We will also reimburse Ms. Jacoby for reasonable expenses in connection with attendance at board and committee meetings.

In conjunction with her appointment to our Board, on January 28, 2026, Ms. Jacoby was automatically granted options to purchase up to 10,000 shares of common stock. The options will vest in three equal installments over a period of three years on the first, second, and third anniversary of the grant or upon change of control.

There are no arrangements or understandings between Ms. Jacoby and any other persons pursuant to which he was appointed to serve on the Board, nor were there any transactions or proposed transactions involving Ms. Jacoby as a participant as required to be disclosed by Item 404(a) of Regulation S-K.

Indemnification and Director Agreement

The indemnification agreement sets forth the circumstances and procedures pursuant to which we agree, by contract, to indemnify our directors and certain of our officers against claims and losses arising from their services as directors and officers. The agreement is substantially identical to the form of indemnification agreement filed as Exhibit 10.1 to our Registration Statement on Form S-1 (File No. 333-135584), as amended, declared effective on January 24, 2007.
