(a)Annual Operational Performance Vesting. Effective as of the last day of each of the Company’s fiscal years 2023-2027 and, as applicable, 2028 and 2029 (each, a “performance year”), there shall become vested the portion of the Option as determined in accordance with Section 2(b) below (such portion of the Option that vests for a performance year, the “Annual Amount” for such year). The Option shall become vested and exercisable as of the date that the Committee verifies the Annual Operational Performance per Diluted Share (AOP) for such performance year; provided, however, the vesting hereunder will be effective as to Participant as of the end of the performance year to which such Annual Amount relates (notwithstanding any termination of Participant’s Continuous Service during the period between the end of such performance year and the verification of the AOP and, in such case, notwithstanding the provisions of Section 3.1(b) of the Stock Option Agreement). For each such performance year, the Committee shall verify the AOP, and shall notify the Company’s Chief Executive Officer of its determination with respect thereto, within ten business days after the Company files its annual report on Form 10-K related to such performance year.
(b)Determining the Annual Amount. For each performance year, the Annual Amount for such performance year shall be determined as follows:
X.In each of the performance years from 2023 to 2027, 20% of the total Option shall be eligible to vest based on AOP as determined below. In addition to that 20% for each such year, in each of the performance years 2024 to 2027 and, if applicable, 2028 and 2029, any amount of Options that was eligible to vest in all prior performance years, but that has not yet vested, shall be eligible to vest based on AOP as determined below. For purposes of calculating the Annual Amount of a performance year: (i) the “Already Vested Options” shall mean the total amount of Options that have vested in prior performance years, if any; and (ii) the “Maximum Eligible Amount” shall mean the total amount of Options eligible to vest in such performance year pursuant to the preceding two sentences, plus the Already Vested Options. For the avoidance of doubt, the Annual Amount of a performance year shall not be less than zero.
Y.If the AOP with respect to such performance year is less than the Minimum AOP Target for such year, none of the Maximum Eligible Amount shall vest for that year. If the AOP with respect to such performance year is equal to the Minimum AOP Target for such year, then the



Annual Amount for such year shall be an amount equal to: (i) 25% of the Maximum Eligible Amount; less (ii) the Already Vested Options. If the AOP with respect to such performance year is equal to or greater than the Maximum AOP Target for such year, then the Annual Amount for such year shall be an amount equal to: (a) 100% of the Maximum Eligible Amount; less (b) the Already Vested Options.
Z.If the AOP with respect to such performance year is between the Minimum AOP Target and the Maximum AOP Target for such year, then the Annual Amount for such year shall be an amount equal to: (1) the Maximum Eligible Amount, multiplied by a percentage equal to (i) 25%; plus (ii) the product of (a) 75%, multiplied by (b) a fraction, (x) the numerator of which is an amount equal to the actual AOP for such year, less the Minimum AOP Target for such year, and (y) the denominator of which is an amount equal to the Maximum AOP Target for such year, less the Minimum AOP Target for such year; less (2) the Already Vested Options. For purposes of illustration, the Annual Amount for such year shall be calculated as follows:
Annual Amount =
Maximum Eligible AmountX(25%+(75%XActual AOP - Minimum AOP Target))
Already Vested options
Maximum AOP Target - Minimum AOP Target
(c) Adjustments of Operational Performance Objectives. The AOP targets specified in this Exhibit B are based upon certain revenue and expense assumptions about the future business of the Company as of the date the Option is granted. Accordingly, in the event that, after such date, the Committee determines, in its sole discretion, that any acquisition or disposition of any business by the Company or any dividend or other distribution (whether in the form of cash, Shares, other securities or other property), recapitalization, reclassification, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Shares or other securities of the Company, issuance of warrants or other rights to purchase Shares or other securities of the Company, or change in applicable laws, regulations, or accounting principles occurs such that an adjustment is determined by the Committee to be appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan or with respect to the Option, then the Committee may, in good faith and in such manner as it may deem equitable, adjust the amounts set forth on this Exhibit B (and/or adjust the definitions of Diluted Shares, EBITDA, Indebtedness and Net Debt) to reflect the projected effect of such transaction(s) or event(s) on AOP.
1.6[Exhibit C to the Agreement (Stock Retention Guidelines) is hereby amended by deleting the provisions therein in their entirety and replacing them with the following:
As a condition to receiving the Option grant, Participant acknowledges and agrees to hold a number of options and/or shares with such value and for such period of time as set forth below:
(a) At all times during Participant’s continued employment by the Company, subject to the below provisions, Participant shall hold an aggregate amount of Company equity with a value equal to or greater than [$_______] (the “Retention Limit”). This Retention Limit will supersede any Retention Limit in any prior dated option agreement between the Company and Participant pursuant to the Plan.
For purposes of this Exhibit C, Company equity shall be equal to (i) the Fair Market Value of any Shares held by the Participant plus (ii) the value of vested Options then held by Participant granted pursuant to the Plan, which will be equal to the Fair Market Value of the Shares underlying the Options over the exercise price.
(b) If at any time after the date hereof the aggregate amount of Company equity held by Participant falls below the Retention Limit because of a decline in the Fair Market Value of the Shares, Participant will have three years to reach the Retention Limit (including by purchases of additional Shares on the open market) before the Committee may exercise any remedies under paragraph (d).



(c) Participant shall not be required to purchase any Shares in the open market in order to initially reach the Retention Limit; provided, however, that notwithstanding the foregoing, Participant may not make any sales of vested Options until the Retention Limit is reached, and thereafter, only to the extent that Participant would, at the time of the sale, be in compliance with the Retention Limit, except that: (i) Participant may sell, surrender or otherwise dispose of Shares to the extent necessary to satisfy the payment of the exercise price and any applicable tax withholding in connection with the exercise of any vested Options in accordance with the applicable option agreement; and (ii) Participant may make sales under 10b5-1 plans in existence on the date hereof so long as such sales would be in compliance with any preexisting Retention Limit.
(d) Participant’s failure to comply with the obligations set forth in this Exhibit C shall result in Participant’s forfeiture of all unvested Options unless otherwise determined by the Committee, in its sole discretion.] [For Officers Only]
2.No other Amendments. Except as expressly set forth in this Amendment, the Agreement remains in full force and effect in all respects.
3.Counterparts. This Amendment may be executed in several counterparts, each of which shall be deemed to be an original, but all of which together shall constitute one and the same agreement. The signatures to this Amendment need not all be on a single copy of this Amendment, and may be electronic signatures (e.g., DocuSign) or copies on portable document format (.pdf) rather than originals, and in each case shall be fully effective as though all signatures were originals on the same copy.
