Explanation of Responses:
(1)  On February 10, 2021 the Reporting Person filed a Form 4 to report sales on February 8, 2021 of an aggregate of 14,206 shares of the issuer's common stock. The Form 4 incorrectly stated that the sales had been made from the Reporting Person's direct holdings. The sales were made by the family trust for which the spouse of the Reporting Person serves as trustee. This Amended Form 4 does not report any new transactions, but rather reflects the correct stock holdings of the family trust as a result of the previously reported February 8, 2021 sales, and correctly reports the direct holdings of the Reporting Person.
(2)  Represents shares held by the Thaler Family Trust for which the spouse of the Reporting Person serves as the trustee.
