In connection with the entry into the Support Agreement, as defined and described in Item 4 below, on February 15, 2023, the Reporting Persons terminated the Group Agreement (as defined in the initial Schedule 13D).

The aggregate purchase price of the 1,025,000 Shares directly owned by Mr. Torok is approximately $615,522, including brokerage commissions.

Item 4.

Purpose of Transaction.

Item 4 is h`ereby amended to add the following:

In connection with the Second Merger Amendment (as defined and described below), on February 13, 2023, the Reporting Persons entered into a voting and support agreement (the “Support Agreement”) with the Issuer and CARISMA Therapeutics Inc. (“Carisma”) pursuant to which the Reporting Persons agreed to vote, at the applicable special meeting to be held in connection with the proposed merger between the Issuer and Carisma (the “Merger”), any and all of their Shares in favor of the Merger and related matters.

In connection with the Support Agreement, the Issuer and Carisma announced that on February 13, 2023 they entered into a Second Amendment to the Agreement and Plan of Merger and Reorganization (the “Second Merger Amendment” and such agreement, as amended, the “Merger Agreement”) to, among other things, (i) increase the expected one-time special cash dividend to be paid to the Issuer’s stockholders to $75 million, subject to the terms and conditions set forth therein, (ii) decrease the Issuer’s minimum net cash required at closing from $75 million to $70 million, and (iii) include Mr. Torok as the Issuer’s designee on the combined company’s board of directors as of the effective time of the Merger in place of a current member of the Issuer’s board of directors formerly designated as such. In addition, as part of the Second Merger Amendment, the Issuer and Carisma agreed to revise the form of Contingent Value Rights Agreement to extend the payment obligations to holders of contingent value rights in the event of any sale of the Issuer’s non-cash assets, including Vicineum, to the period between the effective time of the Merger Agreement and March 31, 2027 (previously December 31, 2023).

Pursuant to the terms of the Support Agreement, the Reporting Persons agreed to certain customary standstill provisions lasting from February 13, 2023 until the later of (A) the earlier of (i) 15 days prior to the deadline under the Issuer’s Amended and Restated By-laws for director nominations and stockholder proposals for the Issuer’s 2024 annual meeting of stockholders, (ii) 100 days prior to the first anniversary of the Issuer’s 2023 annual meeting of stockholders (the “2023 Annual Meeting”), and (iii) such date that is 10 business days after the Issuer’s or Carisma’s receipt of notice from any of the Reporting Persons specifying a material breach of the Support Agreement by the Issuer or Carisma that is not cured within such period, and (B) the date when Mr. Torok is no longer on the board of directors of the combined company (the “Standstill Period”). Pursuant to the Support Agreement, in the event that the Issuer or Carisma has not obtained the requisite stockholder vote under the Merger Agreement by April 1, 2023, the Issuer agreed to (i) provide at least 70 days’ advance notice of the 2023 Annual Meeting to the Reporting Persons, (ii) deem any compliant proposals or director nominations received from the Reporting Persons within 10 days of the receipt by the Reporting Persons of such notice as “timely,” and (iii) not hold the 2023 Annual Meeting less than 70 days after said notice.

Pursuant to the Support Agreement, from the effective time of the Merger until the expiration of the Standstill Period, the Reporting Persons also agreed to vote or cause to be voted all of their respective Shares in accordance with the recommendations of the board of directors of the combined company at all stockholder meetings; provided that (i) to the extent that Institutional Shareholder Services Inc. (“ISS”) or Glass Lewis & Co. LLC (“GL”) recommend otherwise with respect to any proposals (other than as related to the election, removal or replacement of directors), each Reporting Person is permitted to vote in accordance with ISS’s or GL’s recommendation and (ii) each Reporting Person is permitted to vote in its sole discretion with respect to any extraordinary transaction requiring a vote of the combined company’s stockholders.

The Support Agreement terminates upon the earliest to occur of (1) the valid termination of the Merger Agreement, (2) any amendment to the Merger Agreement that reduces the amount or changes the form of any consideration payable to the Reporting Persons in the Merger or otherwise materially and adversely affects the Reporting Persons, (3) the expiration of the Standstill Period, (4) solely in the event that either the Issuer or Carisma has not obtained the requisite stockholder vote under the Merger Agreement by such date, April 1, 2023, or (5) the written agreement of all parties thereto.

The foregoing description of the Support Agreement does not purport to be complete and is qualified in its entirety by reference to the Support Agreement, which is attached as Exhibit 99.1 hereto and is incorporated herein by reference.
