Explanation of Responses:

( 1 )Represents shares withheld to cover a tax liability in connection with the vesting and settlement of the performance-based restricted stock units and restricted stock units, as applicable, described herein. ( 2 )Represents Common Stock earned by the Reporting Person from a performance-based restricted stock unit award granted in Fiscal Year 2022 due to the achievement of certain performance goals, as determined by the Human Capital and Compensation Committee of the Issuer on May 2, 2024 ( 3 )Each restricted stock unit represents the right to receive one share of the Registrant's common stock. ( 4 )Forfeiture restrictions will lapse for 32,072 restricted stock units on April 27, 2025 and 32,073 restricted stock units on April 27, 2026. Earlier potential lapse of forfeiture events set forth in the Company's severance plans apply to this award.

Remarks: This Form 4/A amends and restates the original Form 4 filed by the reporting person on April 30, 2024 ("Original Form 4"). The Original Form 4 incorrectly reported the acquisition of shares related to a performance award on April 25, 2024. However, the final determination and certification of performance occurred on May 2, 2024. This amendment is deemed to withdraw the transactions that were reported in the Original Form 4 to have occurred on April 25, 2024 and report the acquisition of performance-based shares and related tax withholdings on May 2, 2024 and update the ownership amounts accordingly.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.

* 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).

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