Explanation of Responses:

1. Pursuant to the terms of that certain Agreement and Plan of Merger (the "Merger Agreement"), dated as of December 22, 2023, by and among the Issuer, Concentra Biosciences, LLC, a Delaware limited liability company ("Parent") and Concentra Merger Sub II, Inc., a Delaware corporation and a wholly owned subsidiary of Parent ("Merger Sub"), Merger Sub completed a tender offer for shares of common stock of the Issuer (each, a "Share") and thereafter merged with and into the Issuer, effective as of February 14, 2024 (the "Effective Time") with the Issuer surviving the merger.

2. At the Effective Time, each issued and outstanding Share was cancelled and converted into the right to receive (a) $4.05 per Share in cash (the "Cash Amount"), subject to any applicable withholding taxes and without interest, plus (b) one non-transferable contractual contingent value right per Share (each, a "CVR"), which represents the right to receive potential payments, in cash, subject to any applicable tax withholding and without interest, all upon the terms and subject to the conditions as set forth in the Offer to Purchase, as amended, and in the related Letter of Transmittal.

3. Each Issuer restricted stock unit ("Issuer RSU") represents a contingent right to receive one Share.

4. Pursuant to the terms of the Merger Agreement, each outstanding Issuer RSU that was outstanding and unvested immediately prior to the Effective Time vested in full. At the Effective Time, each Issuer RSU then outstanding was cancelled and converted into (i) a cash payment equal to the product of (A) the total number of Shares then underlying such Issuer RSU multiplied by (B) the Cash Amount, without interest and subject to any withholding of taxes; and (ii) one CVR for each Share subject to such Issuer RSU.
