**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	Represents a grant of Restricted Stock Units ("RSUs"), which will be settled in shares of the Issuer's common stock upon vesting. 100% of the RSUs will become vested on the date of the Issuer's 2026 Annual Meeting of Stockholders.
(2)	Effective as of September 2, 2025, the terms of 886,886 unvested RSUs granted to the Reporting Person by the Issuer on November 9, 2022 and originally reported by the Reporting Person in Table I of a Form 4 filed on November 14, 2022 and 33,591 unvested RSUs granted to the Reporting Person by the Issuer on December 16, 2021 and originally reported by the Reporting Person in Table I of a Form 4 on December 20, 2021, were amended by the Issuer's board of directors to make them subject to an additional performance-related vesting condition. As a result of such amendment, the shares of the Issuer's common stock underlying such unvested RSUs will no longer be included in the securities beneficially owned by the Reporting Person as reflected in column 5 of Table I. Upon satisfaction of the relevant performance-related vesting condition, the Reporting Person will again report the acquisition of such shares on a Form 4.
