The Company will enter into an indemnification agreement with Mr. Nicholson in connection with his appointment to the Board which is in substantially the same form as that entered into with the other directors of the Company, filed as Exhibit 10.19 to the Company’s Annual Report on Form 10-K filed on March 6, 2024.

Amended and Restated 2021 Equity Incentive Plan and Awards

As described below, on June 12, 2024, at the Annual Meeting, the stockholders of the Company approved the Amended and Restated TScan Therapeutics, Inc. 2021 Equity Incentive Plan (the “Amended and Restated 2021 Plan”). The Amended and Restated 2021 Plan amends the evergreen provision in the current TScan Therapeutics,

Inc. 2021 Equity Incentive Plan (the “Original 2021 Plan”) to provide that shares of the common stock underlying the Company’s outstanding pre-funded warrants shall be added to the outstanding shares of common stock of the Company to which the annual share replenishment will be applied and to increase the number of shares of the common stock reserved for issuance thereunder by 2,000,000 shares.

The Company’s officers and directors are among the persons eligible to receive awards under the Amended and Restated 2021 Plan in accordance with the terms and conditions thereunder. A detailed summary of the Amended and Restated 2021 Plan is set forth in Proposal No. 3 in the Company’s Definitive Proxy Statement on Schedule 14A for the Annual Meeting, which was filed with the U.S. Securities and Exchange Commission on April 30, 2024. Such detailed summary of the Amended and Restated 2021 Plan and the foregoing description of the Amended and Restated 2021 Plan are qualified in their entirety by reference to the full text of the Amended and Restated 2021 Plan, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated by reference herein.

On June 12, 2024, the Board approved stock option awards for an aggregate of 308,750 shares of voting common stock to non-employee directors, with an exercise price equal to the closing price of the voting common stock on such date of grant of $8.88. These stock option awards are subject to vesting schedules, based on the recipient’s continued service to the Company through the vesting date. The awards to the non-employee directors reflect a modification of the Company’s non-employee director policy to grant an option to purchase 47,500 shares (previously 35,000 shares) of our common stock to each non-employee director on the date of each annual meeting of stockholders of our company, which will vest, subject to the director’s continued service on the Board through such vesting date, in full upon the earlier to occur of the first anniversary of the date of grant or the date of the next annual meeting and to make a one-time grant of an option to purchase 23,750 shares of our common stock to any new non-employee director under the Amended and Restated 2021 Plan.
