These RSUs, tied to the Company's Initial Public Offering ("IPO"), vested on September 27, 2023.

However, the Company and Dr. Buell agreed that it is in the best interests of the Company and its stockholders for Dr. Buell to forfeit that award in lieu of a new award that will vest over a period of five years (see Explanation of Responses #2). Therefore Dr. Buell is returning the RSU Shares to the Company. Dr Buell has thus made the Company whole for the forfeited award by returning 695,750 shares of Company Common Stock to the Company on October 11, 2023 for no consideration.

However, the Company and Dr. Buell agreed that it is in the best interests of the Company and its stockholders for Dr. Buell to forfeit that award in lieu of a new award that will vest over a period of five years (see Explanation of Responses #2). Therefore Dr. Buell is returning the RSU Shares to the Company. Dr Buell has thus made the Company whole for the forfeited award by returning 695,750 shares of Company Common Stock to the Company on October 11, 2023 for no consideration.
