F1	Due to an administrative error, the original Form 4 mistakenly listed the transaction date as March 20, 2024. The transaction actually occurred on March 21, 2024. Accordingly, the exercise price of the stock option is $8.21 per share, as opposed to the exercise price of $9.15 that was listed in the original Form 4.
F2	This option was granted under the Company's 2018 Omnibus Incentive Plan in a transaction exempt under Rule 16b-3 and, except as otherwise provided in the award notice, vests one-fourth on each of the first four anniversaries of the March 21, 2024 grant date.
F3	Due to an administrative error, the original Form 4 mistakenly listed the stock option expiration date as March 20, 2029. The expiration date is actually March 21, 2034.
