Explanation of Responses:

1. This Form 4 reports securities disposed of pursuant to the terms of the Agreement and Plan of Merger, dated January 18, 2022, (the "Merger Agreement"), among UCB S.A., a societe anonyme formed under the laws of Belgium ("Parent"), Zinc Merger Sub, Inc., a Delaware corporation and an indirect wholly owned subsidiary of Parent ("Purchaser") and the Issuer, pursuant to which Purchaser completed a tender offer for shares of common stock of the Issuer (each, a "Share") and thereafter merged with and into the Issuer (the "Merger") effective as of March 7, 2022 (the "Effective Time"). At the Effective Time, each issued and outstanding Share was canceled and converted into the right to receive $26.00 in cash (the "Cash Amount") plus a contingent value right ("CVR"), which CVR represents the right to receive a contingent payment of $2.00 which amount will become payable, if at all, if a specified milestone is achieved on or prior to December 31, 2023.

2. Upon the terms and subject to the conditions set forth in the Merger Agreement, (a) each outstanding option to purchase Shares (each, a "Company Option") with an exercise price less than $26.00 (each, an "In the Money Option"), was canceled and converted into the right to receive an amount in cash equal to, subject to applicable tax withholding, the product of (i) the excess, if any of the Cash Amount over the exercise price per Share underlying such In the Money Option, multiplied by (ii) the total number of Shares subject to such In the Money Options and one CVR; (b) each Company Option with an exercise price equal to or greater than $26.00 but less than $28.00 (each, an "Out of the Money Option"),

3. (Continued from Footnote 2) was canceled and converted into the right to receive, subject to the terms of the Merger Agreement, if and when (and only if and when) payments in respect of CVRs are required to be made, $28.00 in cash (less the applicable exercise price per Share subject to such Out of the Money Option); (c) each Company Option with an exercise price equal to or greater than $28.00, was canceled for no consideration.
