Personal Objectives are reviewed and approved by the Committee for Officers of the Company. Payment of personal objectives is subject to the Company having Net Income for the fiscal year.

(p)“Salary” means the Participant’s base salary rate in effect during the Plan Year (for the avoidance of doubt, excluding bonuses, paid commissions, reimbursed relocation expenses, or any other special pay, but including amounts deferred under any qualified or nonqualified retirement plan of the Company). If a Participant’s Salary changes during the Plan Year, then the Award will be pro-rated to reflect the portion of the year that each Salary was in effect (see Change in Employment Status or Position, below).

(q)“VICP Percentage” means Participant’s participation rate (as a percentage of Salary) under this Plan. The VICP Percentage is based upon the position(s) occupied by the Participant during the Plan Year.

Participation in this Plan is limited to Officers of the Company. A Participant’s VICP Percentage shall be determined and approved by the Committee. Unless otherwise determined by the Committee, a Participant must be employed through the last day of the Plan Year to receive an Award. The Committee, in its sole discretion, may make exceptions to this requirement in the case of Retirement, death or disability or under other circumstances as determined by the Committee. If approved by the Committee, Awards for Participants who leave due to Retirement, disability or death will be in an amount equal to the Award that the Participant would have received had the Participant remained employed through the last day of the Plan Year and then pro-rated by multiplying such amount by a fraction, the numerator of which is the number of days on payroll of the Company (or one of its wholly-owned subsidiaries), and the denominator of which is the number of total days in the Plan Year.

The incentive Performance Goals, each of which stands independently of the others with regard to full Award opportunities, are:

•Revenue

•Personal Objectives

The Performance Goals of an Award and the weighting of the payout relative to threshold, plan target, and full opportunity achievement for each are identified below:

In measuring the degree of attainment of a Performance Goal under this Plan, the Committee reserves the right to adjust, or modify the manner of measuring or evaluating a Performance Goal, for any reason the Committee determines is appropriate, including, but not limited to, by excluding the impact of Extraordinary Events.

Notwithstanding anything in this Plan to the contrary, no Award shall be payable to a Participant under this Plan unless the Company has Net Income for the Plan Year. In the event of results that are below the Revenue and the ROIC threshold levels, only Personal Objectives may have a payout (provided the Participant otherwise satisfies Plan terms); the Revenue and ROIC components have no associated payout until the applicable threshold is exceeded.

(Actual – Threshold) / (Plan Target – Threshold) x [__]% = Revenue Payout %

[__]% + [(Actual – Plan Target) / (Full Opportunity Target – Plan Target) x [__]%] = Revenue Payout %

(Actual – Threshold) / (Plan Target – Threshold) x [__]% = ROIC Payout %

[__]% + [(Actual – Plan Target) / (Full Opportunity Target – Plan Target) x [__]%] = ROIC Payout %

Objective Attainment % x 20% = Personal Objective Payout %

Revenue Payout % + ROIC Payout % + Personal Objective Payout % = Total Incentive Payout %

    

Total Incentive Payout % x VICP Percentage x Participant’s Salary

Eligible participants will be paid Awards on or about November [_, 20_], but in no event later than March [__] of the year following the Plan Year.

Awards to Participants who are hired or promoted to an Officer position after the start of the Plan Year, or who move to a non-Officer position during the Plan Year, are to be pro-rated by multiplying the Award such Participant would have received if employed in an Officer position for the entire year by a fraction, the numerator of which is the number of days in the Plan Year that the Participant spent in an Officer position, and the denominator of which is the total number of days in the Plan Year. If a Participant’s Salary or VICP Percentage changes during the Plan Year, such Participant’s Award will be pro-rated accordingly to reflect the number of days during the Plan Year that each Salary and VICP Percentage was applicable. The Committee may, in its discretion, prorate the Award for a Participant on a leave of absence to reflect only the portion of the Plan Year that the Participant was actively employed to the extent consistent with applicable federal, state, and local laws.

Awards payable hereunder are subject to required tax withholdings and other deductions in accordance with applicable federal, state and local requirements.

The Committee is responsible for the administration of the Plan and its interpretation, including decisions on eligibility, a Participant’s VICP Percentage, and the establishment and determination of the level of achievement of Performance Goals, including Personal Objectives. The Committee’s interpretations and decisions are final and binding. The Committee can amend this Plan at any time for any reason.

Awards under this Plan are considered made under the 2024 OIP and are subject to all the terms and conditions of the 2024 OIP. Compensation under this Plan is subject to the Company’s Compensation Clawback Policy, as it may be amended from

time to time. Nothing in this Plan document or associated communications in any way promises or guarantees the compensation or employment of any Participant with Company or any successor or related company. In the event of a conflict between this Plan and the terms and conditions of a Participant’s employment agreement with the Company (if applicable), the terms and conditions of the Participant’s employment agreement shall govern.
