Explanation of Responses:

*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	Restricted stock units convert into common stock on a one-for-one basis.
(2)	Reflects the amount of shares beneficially owned, including shares received due to automatic dividend reinvestment, as of the date of this report.
(3)	On March 1, 2022, the reporting person was granted 47,438 restricted stock units that vest in five equal annual installments beginning March 1, 2023, subject to continued service. Vested shares will be issued to the reporting person as soon as practicable after the vesting date.
(4)	On March 1, 2024, the reporting person was granted 5,439 restricted stock units that vest in three equal annual installments beginning March 1, 2025, subject to continued service. Vested shares will be issued to the reporting person as soon as practicable after the vesting date.
(5)	On March 3, 2025, the reporting person was granted 33,163 restricted stock units of which 4,963 vest in three equal annual installments beginning March 3, 2026, after market close, and 28,200 vest after 3 years, subject to continued service. Vested shares will be issued to the reporting person as soon as practicable after the vesting date.
(6)	On March 2, 2026, the reporting person was granted 4,629 restricted stock units that vest in three equal annual installments beginning March 2, 2027, subject to continued service. Vested shares will be issued to the reporting person as soon as practicable after the vesting date.
(7)	The reporting person's immediately preceding Form 4, filed on March 3, 2026, inadvertently understated the amount of securities beneficially owned following reported transaction(s) by 920 common shares. The understatement was the net effect of two clerical errors. The first was an understatement of 20 shares in the disclosure of directly owned shares disposed of for tax withholding, resulting in an overstatement of 20 shares beneficially owned. To clarify, the Form 4 filed on March 3, 2026 should have disclosed that a total of 3,955 directly owned shares were disposed of for tax withholding (not 3,935 shares). The second clerical error was the omission of 940 directly held shares that had been previously been reported as acquired. The net of these transactions was an understatement of 920 common shares. The amount shown in this table corrects those two inadvertent clerical errors.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
