In addition, the number of shares available for issuance under the Amended and Restated 2024 Plan may be increased from time to time by shares of Common Stock subject to outstanding awards under the Registrant's 2021 Equity and Incentive Compensation Plan (the "2021 Plan"), the 2018 Equity and Incentive Compensation Plan (the "2018 Plan") and the Amended and Restated 2009 Omnibus Incentive Compensation Plan (the "2009 Plan" and, together with the 2021 Plan and the 2018 Plan, the "Predecessor Plans") that are forfeited, cancelled, expire, settled for cash (in whole or in part) or unearned (in whole or in part), as applicable, after February 3, 2024 at a rate of one share for every one share subject to stock option awards and 1.75 shares for every one share subject to awards other than stock options.  

Note 1c. Estimated solely for calculating the amount of the registration fee, pursuant to paragraphs (c) and (h) of Rule 457 under the Securities Act, on the basis of the average of the high and low sale prices of such securities on the New York Stock Exchange on May 21, 2026, a date within five business days prior to filing.
