Officers who also serve on the Board of Directors are not compensated separately for their service on the Board of Directors.

Cash compensation for directors, payable quarterly, is as follows:

Base director compensation - $20,000 per year (except for Dr. Bernards, who was paid an additional annual cash fee of $40,000, in lieu of the annual June 30 grant of stock option as described below, through March 31, 2024)

Member of audit committee – additional $5,000 per year

Member of any other committees – additional $2,500 per year

In conjunction with the Company’s efforts to preserve cash, the Board of Directors approved amendments to this compensation program, such that for the quarters ended June 30, 2024 through December 31, 2025, the non-officer directors (including Dr. Bernards) have received or will receive, in lieu of cash compensation, stock options exercisable for a period of five years, vesting immediately, to purchase common stock at an exercise price based on the closing market price upon issuance, with the amount of such stock options equal to the cash payment such director would otherwise have been entitled to receive for such quarter, divided by their quarterly value as determined pursuant to the Black-Scholes option-pricing model. On September 30, 2025, the Board of Directors approved an amendment to this compensation program such that at each quarter end, each non-officer director will have the choice as to whether to receive their quarterly compensation in cash or in stock options exercisable for a period of five years, vesting immediately, to purchase common stock at an exercise price based on the closing market price upon issuance, with the amount of such stock options equal to the cash payment such director would otherwise have been entitled to receive for such quarter, divided by their quarterly value as determined pursuant to the Black-Scholes option-pricing model.

Equity compensation for directors is as follows:

Appointment of new directors – The Company grants options to purchase 25,000 shares of common stock, exercisable for a period of five years, at the closing market price on the date of grant, vesting 50% on the grant date and the remaining 50% vesting 12.5% on the last day of each calendar quarter beginning in the quarter immediately subsequent to the date of the grant until fully vested, subject to continued service. At the discretion of the Board of Directors, for a nominee to the Board of Directors who is restricted by their respective institution or employer from receiving equity-based compensation, in lieu of the grant of such stock options, the Company may elect to pay a one-time cash fee of $100,000 to such director, payable upfront.

Annual grant of options to directors – Effective on the last business day of the month of June, the Company grants options to purchase 10,000 shares of common stock, exercisable for a period of five years, at the closing market price on the date of grant, vesting 12.5% on the last day of each calendar quarter beginning in the quarter immediately subsequent to the date of grant until fully vested, subject to continued service. If any director has served for less than 12 full calendar months on the grant date, the amount of such stock option grant is prorated based on the length of service of such director. At the discretion of the Board of Directors, for a nominee to the Board of Directors who is restricted by their respective institution or employer from receiving equity-based compensation, in lieu of the grant of such stock options, the Company may elect to pay an annual cash fee of $40,000 to such director, payable quarterly.
