1.2Status of Plan. The Plan is intended to continue to be an unfunded plan maintained primarily for the purpose of providing deferred compensation for a “select group of management or highly compensated employees” within the meaning of such phrase for purposes of Sections 201(2), 301(a)(3) and 401(a)(1) of ERISA, and as such it is intended that the Plan will continue to be exempt from the participation and vesting, funding, and fiduciary responsibility requirements of Title I of ERISA.

(a)if the Form of Payment for the Account that is to be changed is the earlier of the March of a specified Calendar Year and the first March or September that is at least six months following the Participant’s Separation from Service, then the subsequent election to change the Form of Payment must be made not less than 12 months before March 1 of the specified Calendar Year; if the subsequent election is not timely made, the change shall not be effective and the prior Form of Payment for the Account shall continue to apply; and

(b)regardless of the Form of Payment for the Account that is to be changed, the subsequent election to change the Form of Payment shall not take effect until the 12-month anniversary of the date on which the subsequent election is made; if the Participant has a Separation from Service before the 12-month anniversary of the date on which the subsequent election is made, the change shall not be effective and the prior Form of Payment for the Account shall continue to apply.

8.3Effects of Change to Form of Payment.

(a)Effects. If a subsequent election by a Participant to change the Form of Payment of any Account pursuant to Section 8.1 becomes effective pursuant to Section 8.2,

then (i) the Time of Payment for the affected Account shall be delayed by five years, and (ii) to the extent any benefits accrued under a Participant’s Supplemental Contributions Account or Discretionary Contribution Account(s) before the date of the subsequent election were not subject to a condition on payment imposed pursuant to Section 6.6, such benefits accrued prior to the date of the subsequent election shall become subject to any condition on payment imposed pursuant to Section 6.6.

(b)Examples. The following examples show how the five-year delay is applied:

(i)if the Account was payable on the first March or September that is at least six months following the Participant’s Separation from Service, then the Account will become payable on the first March or September that is at least six months following the five-year anniversary of the Participant’s Separation from Service; and

(ii)if the Account was payable on the earlier of the March of a specified Calendar Year and the first March or September that is at least six months following the Participant’s Separation from Service, then the Account will become payable on the earlier of the March of the fifth Calendar Year following the previously specified Calendar Year and the first March or September that is at least six months following the five-year anniversary of the Participant’s Separation from Service).

8.4Ineligible Accounts. A Participant may not elect to change the Form of Payment of his or her Pre-2024 Entegris Account or any Discretionary Contribution Account.

9.1Hypothetical Investments. The Administrative Committee shall establish from time to time the hypothetical investment(s) made available under the Plan for purposes of valuing Accounts (each, an “Hypothetical Investment”). At any time, the Administrative Committee may, in its discretion, add one or more additional Hypothetical Investments under the Plan. In addition, the Administrative Committee, in its sole discretion, may discontinue any Hypothetical Investment at any time, and provide for the portions of Participants’ Accounts designated to the discontinued Hypothetical Investment to be reallocated to another Hypothetical Investment.

9.2Account Adjustments for Hypothetical Investments. While a Participant’s Accounts do not represent the Participant’s ownership of, or any ownership interest in, any particular assets, the Participant’s Accounts shall be adjusted in accordance with the Hypothetical Investment(s), subject to the conditions and procedures set forth herein or established by the Administrative Committee from time to time. Any notional cash earnings generated under a Hypothetical Investment (such as interest and cash dividends and distributions) shall, at the Administrative Committee’s sole discretion, either be deemed to be reinvested in that Hypothetical Investment or reinvested in one or more other Hypothetical Investment(s) designated by the Administrative Committee. All notional acquisitions and dispositions of Hypothetical Investments under a Participant’s Account shall be deemed to occur at such times as the Administrative Committee shall determine to be administratively feasible in its sole discretion and the Participant’s Accounts shall be adjusted accordingly. In addition, a Participant’s Accounts may be adjusted from time to time, in accordance with procedures and practices established by the Administrative Committee, in its sole discretion, to reflect any notional transactional costs and other fees and expenses relating to the deemed

investment, disposition or carrying of any Hypothetical Investment for the Participant’s Accounts.

9.3Direction of Hypothetical Investments. Subject to the terms of the Plan and applicable laws, the Administrative Committee may allow Participants to designate how they would prefer the aggregate of their Accounts be deemed to be invested among the Hypothetical Investments made available by the Administrative Committee, subject to any limitations, operating rules and procedures as may be required by the Administrative Committee or its designated agents from time to time; provided, however, the Administrative Committee shall have the authority to specify an allocation of all or a portion of any Participant’s Accounts among one or more Hypothetical Investments different from the allocation designated by the Participant, in which case the designation by the Administrative Committee shall control. If Participants are allowed to designate how they would prefer the aggregate of their Accounts be deemed to be invested and one of the Hypothetical Investments made available relates to the ownership interests of the Administrative Committee, the Administrative Committee shall adopt such administrative procedures and limitations on the ability of Participants to allocate Accounts to or out of such Hypothetical Investment as the Administrative Committee determines necessary or advisable to avoid a violation of applicable laws. Each Account shall be adjusted to reflect the aggregate performance of the Hypothetical Investment(s).

9.4No Guarantee of Return. Neither the Company, its Participating Affiliates, the Administrator nor the Administrative Committee make any representation or guarantee regarding whether and to what extent there will be any increase or decrease in the value of a Participant’s Accounts. It is possible that a Participant’s Accounts will go down in value. The Company, its Participating Affiliates, the Administrator and the Administrative Committee shall not be liable or responsible for, and the Participant assumes all risk in connection with, any decrease (or lack of increase) in the Participant’s Accounts.

10.1Payments. Each of a Participant’s Accounts will be paid at the Time of Payment and in the Form of Payment applicable to that Account, as determined pursuant to Section 5.4 for Base Salary Deferral Account, Section 5.5 for a Bonus Deferral Account, and Section 6.3 for the Supplemental Contributions Account, in each case subject to any applicable delay under Section 8.3, and pursuant to Section 6.4 for a Discretionary Contribution Account and Section 7.1 for a Pre-2024 Entegris Account. Notwithstanding the foregoing, in the event of the death of a Participant, the balance of the Participant’s Accounts will be paid to the Participant’s Beneficiary or Beneficiaries in a lump sum no later than December 31 of the Calendar Year following the Calendar Year that includes the date of the Participant’s death.

10.2Amount of Payment. The amount of payment for a Participant’s Account shall be the vested value of an Account (as adjusted pursuant to Article 9) through a date (determined by the Administrative Committee in its sole discretion) preceding the date on which the payment is made.

10.3Installment Payments. In the event that an Account is payable in installments, the amount of each installment will be the value of the Account as of the installment payment date, determined in accordance with Section 10.2, multiplied by a fraction, the numerator of which is one and the denominator of which is the number of remaining payments (e.g., if the Participant elected to have an Account paid in five installments, the first annual installment payment would be the amount of the Participant’s Account multiplied by 1/5, the second

annual installment payment would be the remaining amount of the Participant’s Account multiplied by 1/4, etc.).

10.4Acceleration of Payments. Except as specifically permitted by this Section 10.4 or in other sections of the Plan, no acceleration of the time or schedule of any payment may be made hereunder. Notwithstanding the foregoing, payments may be accelerated hereunder by the Administrative Committee in the following circumstances, subject to and in accordance with the provisions of Section 1.409A-3(j)(4) of the Treasury Regulations:

(a)De Minimis Cash-Out. The Administrative Committee shall have the discretion to require a mandatory lump sum payment of a Participant’s aggregate Accounts, provided that: (i) the payment results in the termination and liquidation of the Participant’s interest in the Plan and all arrangements which would be aggregated with the Plan under Section 409A; and (ii) the payment is not greater than the applicable dollar amount under Section 402(g)(1)(B) of the Code for the Calendar Year of acceleration (e.g., $22,500 for 2023).

(b)Payment of FICA Taxes. The Plan will permit the acceleration of the Time of Payment to pay the Federal Insurance Contributions Act (FICA) taxes imposed on compensation deferred by a Participant under the Plan (the “FICA Amount”). Additionally, the Plan will permit the acceleration of the time or schedule of a payment to pay the income tax at source on wages imposed as a result of the payment of the FICA Amount, and to pay the additional income tax at source on wages attributable to the pyramiding wages and taxes. However, the total payment under this acceleration provision will not exceed the aggregate of the FICA Amount, and the income tax withholding related to such FICA Amount.

(c)Payment upon Income Inclusion under Section 409A. The Plan will permit the acceleration of the time or schedule of a payment to a Participant at any time the Plan fails to meet the requirements of Section 409A. Such payment may not exceed the amount required to be included in income as a result of the failure to comply with the requirements of Section 409A.

10.5Delay of Payments. The Administrative Committee may, in its sole discretion, delay the time of a payment under the Plan to a time otherwise permitted under Section 409A in accordance with the requirements, restrictions and limitations of Section 1.409A-2(b)(7) of the Treasury Regulations.

10.6Actual Date of Payment. To the extent permitted by Section 409A:

(a)If calculation of the amount of a payment is not administratively practicable due to events beyond the control of the Participant (or the Participant’s Beneficiary), the payment may be delayed, provided that the payment must be made as soon as calculation of the amount of the payment is administratively practicable. The inability of the Administrative Committee to calculate the amount or timing of a payment due to a failure of the Participant (or the Participant’s Beneficiary) to provide reasonably available information necessary to make such calculation does not constitute an event beyond the control of the Participant.

(b) If the making of a payment at the date specified under the Plan would jeopardize the ability of the Company to continue as a going concern, the payment may be delayed, provided that the payment must be made as soon as administratively practicable after the making of the payment would not have such effect.

10.7Unforeseeable Emergency. In the event that a Participant experiences an Unforeseeable Emergency, the Participant may petition the Administrative Committee to

receive a partial or full payout of vested amounts credited to the Participant’s Accounts. The Administrative Committee shall determine, in its sole discretion, whether the requested payout shall be made, the amount of the payout and the Account(s) from which the payout will be made; provided, however, that the payout shall not exceed the lesser of the vested balance of the Participant’s Accounts or the amount reasonably needed to satisfy the Unforeseeable Emergency plus amounts necessary to pay taxes reasonably anticipated as a result of the distribution. In making its determination under this Section 10.7, the Administrative Committee shall be guided by the requirements of Section 409A and any other related prevailing legal authorities, and the Administrative Committee shall take into account the extent to which a Participant’s Unforeseeable Emergency is or may be relieved through reimbursement or compensation by insurance or otherwise or by the liquidation by the Participant of his or her assets (to the extent the liquidation of such assets would not itself cause severe financial hardship).

10.8Discharge of Obligations. The payment to a Participant or his or her Beneficiary of the Participant’s Accounts shall discharge all obligations of the Company to such Participant and his or her Beneficiary under the Plan.

10.9Payment to Representative; Uncertainty as to Recipient.

(a)Incompetency. Any person entitled to receive a payment under the Plan shall be presumed to be mentally competent until the date on which the Administrative Committee receives a written notice in a form and manner acceptable to the Administrative Committee that such person is incompetent and that a guardian, conservator or other person legally vested with the interest of his or her estate has been appointed. If a guardian, conservator or other person legally vested with the interest of the estate of any person receiving or claiming payments under the Plan is appointed, payments under the Plan may be made to such guardian, conservator or other person provided that the proper proof of appointment and continuing qualification is furnished in a form and manner acceptable to the Administrative Committee.

(b)Minors. If a distribution is to be made to a minor and no guardian or conservator has been appointed with respect to such minor, payments under the Plan may be made to a parent of such minor or an adult with whom the minor maintains his residence, or to the custodian for such minor under the Uniform Gifts to Minors Act or Uniform Transfers to Minors Act, if such is permitted by the laws of the state in which the minor resides.

(c)Uncertainty. Notwithstanding Section 10.1, the Administrative Committee may, at its option, in the event of doubt as to the proper individual or entity entitled to receive payment under the Plan, pay over any and all sums of money to a court of appropriate jurisdiction, as determined by the Administrative Committee in its sole discretion, to await disposition after determination of the rightful individual or entity entitled thereto by final judgment or otherwise.

(d)Discharge of Liability. Any payments made in accordance with this Section 10.9 shall be a complete discharge of any liability of the Company for such payments. There shall be no accrual of interest or other earnings on payments delayed pending determination of the proper recipient under this Section 10.9.

11.1Designation. Each Participant may designate any person or persons to receive any benefits payable under the Plan upon the Participant’s death, and the designation may be

changed from time to time by the Participant by filing a new designation. Each designation will revoke all prior designations by the same Participant, shall be in the form prescribed by the Administrative Committee, and shall be effective only when filed in writing with the Administrative Committee during the Participant’s lifetime. For Participants who made a beneficiary designation under the Predecessor Plan prior to the Effective Date, such beneficiary designation will apply to the Participant’s benefits under the Plan (including the Participant’s Pre-2024 Entegris Account) until changed from time to time by the Participant by filing a new designation pursuant to this Section 11.1.

11.2No Valid Designation. In the absence of a valid Beneficiary designation, or if, at the time of a Participant’s death, there is no living Beneficiary validly named by the Participant, the Company shall pay the deceased Participant’s Accounts to the Participant’s estate, which shall be considered the Beneficiary for purposes of the Plan.

11.3Uncertainty. If a question arises as to the existence or identity of anyone entitled to receive a death benefit payment under the Plan, or if a dispute arises with respect to any death benefit payment under the Plan, the Company may distribute the payment to the Participant’s estate without liability for any tax or other consequences, or may take any other action which the Administrative Committee deems to be appropriate.

12.1Claims Procedure. A claim for benefits under the Plan shall be adjudicated in accordance with this Article 12. This Article 12 is based on the claims procedures described in Section 2560.503-1 of the Department of Labor Regulations. If any provision of this Article 12 conflicts with the requirements of those regulations, the requirements of those regulations will prevail. If and to the extent that the Plan is determined not to be a “pension plan” for purposes of Section 3(2) of ERISA, any references herein to a Claimant’s rights under ERISA shall be void and inapplicable.

(a) Claim. A Participant, Beneficiary or other person who believes he or she is entitled to any Plan benefit under the Plan (a “Claimant”) may file a claim with the Administrative Committee. A claim must be in writing. The Administrative Committee shall review the claim itself or appoint an individual or entity to review the claim.

(b)Claim Decision. The Claimant shall be notified within 90 days after the claim is filed, whether the claim is allowed or denied, unless the Claimant receives written notice from the Administrative Committee or appointee of the Administrative Committee prior to the end of the 90-day period stating that special circumstances require an extension of the time for decision. Such extension is not to extend beyond the day which is 180 days after the day the claim is filed as long as the Administrative Committee notifies the Claimant of the circumstances requiring the extension, and the date as of which a decision is expected to be rendered. If the Administrative Committee denies the claim, it must provide to the Claimant, in writing or by electronic communication: (i) the specific reasons for such denial; (ii) specific reference to pertinent provisions of the Plan on which such denial is based; (iii) a description of any additional material or information necessary for the Claimant to perfect his or her claim, by providing such material to the Administrative Committee within 45 days, and an explanation why such material or such information is necessary; and (iv) a description of the Plan’s appeal procedures and the time limits applicable to such procedures, including a statement of the Claimant’s right to bring a civil action under Section 502(a) of ERISA following a denial of the appeal of the denial of the benefits claim.

(c)Review Procedures.

(i)A request for review of a denied claim must be made in writing to the Administrative Committee within 60 days after receiving notice of denial. The decision upon review will be made within 60 days after the Administrative Committee’s receipt of a request for review. If the Administrative Committee determines that an extension of time for processing is required, written notice of the extension shall be furnished to the Claimant (which will include the expected date of rendering a decision) prior to the termination of the initial period, but in no event will the extension exceed 60 days.

(ii)The reviewer shall afford the Claimant an opportunity to review and receive, without charge, all relevant documents, information, and records and to submit issues and comments in writing to the Administrative Committee. The reviewer shall take into account all comments, documents, records, and other information submitted by the Claimant relating to the claim regardless of whether the information was submitted or considered in the benefit determination. Upon completion of its review of an adverse initial claim determination, the Administrative Committee will give the Claimant, in writing or by electronic notification, a notice containing: (1) its decision; (2) the specific reasons for the decision; (3) the relevant Plan provisions on which its decision is based; (4) a statement that the Claimant is entitled to receive, upon request and without charge, reasonable access to, and copies of, all documents, records and other information in the Plan’s files which is relevant to the Claimant’s claim for benefit; (5) a statement describing the Claimant’s right to bring an action for judicial review under ERISA Section 502(a); and (6) if an internal rule, guideline, protocol, or other similar criterion was relied upon in making the adverse determination on review, a statement that a copy of the rule, guideline, protocol, or other similar criterion will be provided without charge to the Claimant upon request.

(d)Calculation of Time Periods. For purposes of the time periods specified in this Article 12, the period of time during which a benefit determination is required to be made begins at the time a claim is filed in accordance with the Plan’s procedures without regard to whether all the information necessary to make a decision accompanies the claim. If a period of time is extended due to a Claimant’s failure to submit all information necessary, the period for making the determination shall be tolled from the date the notification is sent to the Claimant until the date the Claimant responds.

(e)Failure of Claimant to Follow Procedures. A Claimant’s compliance with the foregoing provisions of this Article 12 is a mandatory prerequisite to the Claimant’s right to commence arbitration pursuant to Section 12.2 or any other form of any legal action with respect to any claim for benefits under the Plan.

12.2Arbitration of Claims. All claims or controversies arising out of or in connection with the Plan shall, subject to the initial claim and review process provided for in Section 12.1, be resolved through arbitration as provided in this Section 12.2. A Claimant requesting arbitration with respect to a claim must notify the Administrative Committee of such request, in writing, on or before the last day of the 12th month beginning after the date such Claimant received a denial on review following exhaustion of the claim and review process described in Section 12.1. Except as otherwise provided or by mutual agreement of the parties, any arbitration shall be administered by Judicial Arbitration & Mediation Services, Inc. (“JAMS”), in accordance with the JAMS procedure then in effect. The arbitration shall be held in the JAMS office nearest to where the Claimant is or was last employed by the Company or a Participating Affiliate or at a mutually agreeable location. The prevailing party in the arbitration shall have the right to recover its reasonable attorney’s fees, disbursements and costs of the arbitration

(including enforcement of the arbitration decision), subject to any contrary determination by the arbitrator.

12.3Knowledge of Facts by Participant Imputed to Beneficiary. Knowledge of all facts that a Participant knew or reasonably should have known shall be imputed to every Claimant who is or claims to be a Beneficiary of the Participant or otherwise claims to derive an entitlement by reference to the Participant for the purpose of applying the time periods specified in this Article 12.

13.1Amendment. The Administrator may, at any time, amend or modify the Plan in whole or in part; provided, however, that, except to the extent necessary to bring the Plan into compliance with Section 409A, no amendment or modification shall be effective to decrease the value of a Participant’s Account in existence at the time an amendment or modification is made.

13.2Termination. The Administrator reserves the right to terminate and liquidate the Plan in accordance with Section 1.409A-3(j)(4)(ix) of the Treasury Regulations.

14.1Participant Information. Each Participant and Beneficiary must inform the Administrative Committee of any change in his or her address. All notices to any person from the Administrative Committee will be sent to the last known address of such person and there will be no further obligation to such person in the event any such communication is not received by the person. In addition, each Participant and Beneficiary will promptly furnish information to the Administrative Committee as to any and all facts which the Administrative Committee may reasonably require concerning any person affected by the terms of the Plan. The Administrative Committee shall not be obligated to search for any Participant or Beneficiary beyond the sending of a registered letter to the last known address.

14.2Corrections. If any fact relating to a Participant, Beneficiary or any other person has been misstated, the correct fact may be used to determine the amount of benefit payable to him or her or to such other person. If overpayments or underpayments have been made because of such incorrect statement, the amount of any future payments may be appropriately adjusted.

14.3Severability. In case any provision of the Plan shall be illegal or invalid for any reason, said illegality or invalidity shall not affect the remaining parts hereof, but the Plan shall be construed and enforced as if such illegal or invalid provision had never been inserted herein.

14.4Nonassignability. Neither a Participant nor any other person shall have any right to commute, sell, assign, transfer, pledge, anticipate, mortgage or otherwise encumber, transfer, hypothecate, alienate or convey in advance of actual receipt, the amounts, if any, payable hereunder, or any part hereof, which are, and all rights to which are expressly declared to be, unassignable and non-transferable. No part of the amounts payable shall, prior to actual payment, be subject to seizure, attachment, garnishment (except to the extent the Company or a Participating Affiliate may be required to garnish amounts from payments due under the Plan pursuant to applicable law) or sequestration for the payment of any debts, judgments, alimony or separate maintenance owed by a Participant or any other person, be

transferable by operation of law in the event of a Participant’s or any other person’s bankruptcy or insolvency or be transferable to a spouse as a result of a property settlement or otherwise. If any Participant, Beneficiary or successor in interest is adjudicated bankrupt or purports to commute, sell, assign, transfer, pledge, anticipate, mortgage or otherwise encumber transfer, hypothecate, alienate or convey in advance of actual receipt, the amount, if any, payable hereunder, or any part thereof, the Administrative Committee, in its discretion and subject to Section 409A, may cancel such distribution or payment (or any part thereof) to or for the benefit of such Participant, Beneficiary or successor in interest in such manner as the Administrative Committee shall direct.

14.5Loans. No loans to Participants shall be permitted under the Plan.

14.6Not a Contract of Employment. The terms and conditions of the Plan shall not be deemed to constitute a contract of employment between the Company or any Participating Affiliate and any Eligible Employee or Participant. Nothing in the Plan shall be deemed to give an Eligible Employee or Participant the right to be retained in the employment or service of the Company or any Participating Affiliate or to interfere with the right of the Company or a Participating Affiliate to discipline or discharge the Eligible Employee or Participant at any time.

14.7Unsecured General Creditor Status of Participant. Payment to a Participant, Beneficiary or other person hereunder shall be made from assets which shall continue, for all purposes, to be part of the general, unrestricted assets of the Company and no person shall have any interest in any such asset by virtue of any provision of the Plan. The Company’s obligation hereunder shall be an unfunded and unsecured promise to pay money in the future. To the extent that any person acquires a right to receive payments from the Company under the provisions hereof, such right shall be no greater than the right of any unsecured general creditor of the Company and no such person shall have or acquire any legal or equitable right, interest or claim in or to any property or assets of the Company.

14.8Unclaimed Benefits. In the case of a benefit payable on behalf of such Participant, if the Administrative Committee is unable, after reasonable and diligent effort, to locate the Participant or Beneficiary to whom such benefit is payable, such Plan benefit may be forfeited to the Company upon the Administrative Committee’s determination one year after the date the benefit first became payable. Notwithstanding the foregoing, if, subsequent to any such forfeiture, the Participant or Beneficiary to whom such Plan benefit is payable makes a valid claim for such Plan benefit, such forfeited Plan benefit shall be paid by the Company to the Participant or Beneficiary, without interest from the date it would have otherwise been paid. Notification by certified or registered mail to the last known address of the person is deemed a reasonable and diligent effort to locate the person.

14.9Governing Law. Except to the extent preempted by federal law, the provisions of the Plan shall be construed and interpreted according to the internal laws of the Commonwealth of Massachusetts, without regard to its conflicts of laws principles.

14.10Coordination with Other Benefits. The benefits provided for a Participant under the Plan are in addition to any other benefits available to such Participant under any other plan or program for employees of the Company or a Participating Affiliate. The Plan shall supplement and shall not supersede, modify or amend any other such plan or program except as may otherwise be expressly provided.

14.11Taxes.

(a)Tax Withholding. For each Calendar Year in which a deferral amount is being withheld from a Participant pursuant to the Plan or unvested amounts under the Plan

become vested, the Company or the applicable Participating Affiliate shall withhold from the portion of the Participant’s compensation that is not being deferred, all applicable taxes, and any and all other amounts required to be withheld under Federal, state or local law and other applicable guidance. The Company or the applicable Participating Affiliate will also withhold from any payment made under the Plan to a Participant or Beneficiary, and from any amount taxable under Section 409A, all applicable taxes, and any and all other amounts required to be withheld under Federal, state or local law and other applicable guidance, and the amount withheld shall reduce the amount payable to the Participant or Beneficiary.

(b)Compliance with Section 409A. The benefits under the Plan are intended to comply with the requirements of Section 409A, and the Plan and the forms and materials used in the administration and operation of the Plan shall be interpreted and construed in a manner consistent with such intention. Notwithstanding the foregoing, neither the Company nor any Participating Affiliate represent or guarantee that the benefits under the Plan comply with the requirements of Section 409A, and neither the Company nor any Participating Affiliate shall be liable to any Participant, Beneficiary or other person for any Federal, state or local taxes, penalties or interest imposed on such person as a result of a failure to comply with Section 409A. For purposes of Section 409A, payments to be made in a series of installments shall be treated as separate payments.

(c)Participants Should Consult Advisors. Neither the Administrator, the Administrative Committee, the Company, a Participating Affiliate, nor any of the Company’s or Participating Affiliate’s directors, officers, employees or agents make any representation or warranty with respect to the tax (including Section 409A), financial, estate planning or other legal implications of participation in the Plan. Participants should consult with their own tax, financial and legal advisors with respect to their participation in the Plan.

IN WITNESS WHEREOF, the Company has caused the Plan to be executed, effective as of the 1st day of January, 2024.
