Entegris, Inc. 2019 RSU Unit Award Agreement

Award Date. This Agreement shall take effect as of the date specified in the Restricted Stock Plan section on the Overview tab as the Award Date provided to you online at www.stockplanconnect.com (the “Award Date”).

Restricted Stock Units Subject to Award. The Award consists of that number of restricted stock units (the “RSU”) with respect to the Stock that has been approved for the Award to Participant by the Administrator. Each RSU is equivalent to one share of the Stock. The Participant’s rights to the RSU are subject to the restrictions described in this Agreement and in the Plan (which is incorporated herein by reference with the same effect as if set forth herein in full) in addition to such other restrictions, if any, as may be imposed by law.

Meaning of Certain Terms. The term “vest” as used herein with respect to any RSU means the lapsing of the restrictions described herein with respect to such RSU.

Nontransferability of RSUs. The RSU acquired by the Participant pursuant to this Agreement shall not be sold, transferred, pledged, assigned or otherwise encumbered or disposed of except as provided below and in the Plan.

Forfeiture Risk. Except as otherwise provided in this Agreement, if the Participant ceases to be employed or retained by the Company and/or its subsidiaries for any reason any then outstanding and unvested RSU acquired by the Participant hereunder shall be automatically and immediately forfeited. The Participant hereby appoints the Company as the attorney-in-fact of the Participant to take such actions as may be necessary or appropriate to effectuate the cancellation of a forfeited RSU.

Vesting and Settlement of RSUs. The RSU acquired hereunder shall vest in accordance with the provisions of this Article I, Section 1.6 and applicable provisions of the Plan, as follows:

Dividend Equivalent Rights. The Participant shall not be entitled: (i) to receive any dividends or other distributions paid with respect to the Stock to which the RSU relates, or (ii) to vote any Stock with respect to which the RSU relates, unless and until, and only to the extent, the RSU becomes vested and the Participant becomes a stockholder of record with respect to such shares of Stock. Notwithstanding the foregoing, as of each date on which the Company pays an ordinary cash dividend to record owners of shares of Stock, the Participant’s account shall, as of each such dividend date, be credited with a cash amount (without interest) equal to the product of the total number of shares subject to the RSU immediately prior to such dividend date multiplied by the dollar amount of the cash dividend paid per share of Stock by the Company on such dividend date (such amount, the “Dividend Equivalent Amount”). The Dividend Equivalent Amount shall be subject to the same vesting conditions and settlement terms as the RSU shares to which they relate.

Sale of Vested Shares. The Participant understands that Participant will be free to sell any Stock with respect to which the RSU relates once the RSU has vested and settled, subject to (i) satisfaction of any applicable tax withholding requirements with respect to the vesting of such RSU; (ii) the completion of any administrative steps (for example, but without limitation, the transfer of certificates) that the Company may reasonably impose; and (iii) applicable requirements of federal and state securities laws.

Certain Tax Matters. The Participant expressly acknowledges that the award or vesting of the RSU acquired hereunder, may give rise to “wages” subject to withholding. The Participant expressly acknowledges and agrees that Participant’s rights hereunder are subject to Participant promptly paying to the Company all taxes required to be withheld in connection with such award, vesting, settlement and/or payment. Unless the Administrator determines otherwise, such payment of Participant’s withholding tax obligations shall be made through net share settlement procedures whereby that number of the vesting shares needed to cover the withholding tax obligation (calculated using the Fair Market Value of the Company’s stock on the date of vest) shall be cancelled to fund the Company’s payment of the withholding tax obligation and the net shares remaining after such cancellation shall be credited to Participant’s account.

Definitions. Except as otherwise expressly provided, all terms used herein shall have the same meaning as in the Plan. The term “Administrator” means the Management Development & Compensation Committee of the Company’s Board of Directors.

Change in Control    

Retirement. If Participant is an employee of the Company and ceases to be an employee due to retirement with the consent of the Administrator, Participant will be entitled to immediate vesting of

Equitable Adjustments. The Award is subject to adjustment pursuant to Section 15.1 of the Plan.

No Understandings as to Employment etc. The Participant further expressly acknowledges that nothing in the Plan or any modification thereto, in the Award or in this Agreement shall constitute or be evidence of any understanding, express or implied, on the part of the Company to employ or retain the Participant for any period or with respect to the terms of the Participant’s employment or to give rise to any right to remain in the service of the Company or of any subsidiary or affiliate of the Company, and the Participant shall remain subject to discharge to the same extent as if the Plan had never been adopted or the Award had never been made.

Data Protection Waiver. Participant understands and agrees that in order to process and administer the Award and the Plan, the Company and the Administrator may process personal data and/or sensitive personal information concerning the Participant. Such data and information includes, but is not limited to, the information provided in the Award grant package and any changes thereto, other appropriate personal and financial data about Participant, and information about Participant’s participation in the Plan and transactions under the Plan from time to time. Participant hereby gives his or her explicit consent to the Company and the Administrator to process any such personal data and/or sensitive personal information. Participant also hereby gives his or her explicit consent to the Company and the Administrator to transfer any such personal data and/or sensitive personal data outside the country, in which Participant works or is employed, and to the United States. The legal persons granted access to such Participant personal data are intended to include the Company, the Administrator, the outside plan administrator as selected by the Company from time to time, and any other compensation consultant or person that the Company or the Administrator may deem appropriate for the administration of the Plan or the Award. Participant has been informed of his or her right of access and correction to Participant’s personal data by contacting the Company. Participant also understands that the transfer of the information outlined herein is important to the administration of the Award and the Plan and failure to consent to the transmission of such information may limit or prohibit Participant’s participation under the Plan and/or void the Award.

Savings Clause. In the event that Participant is employed or provides services in a jurisdiction where the performance of any term or provision of this Agreement by the Company: (i) will result in a breach or violation of any statute, law, ordinance, regulation, rule, judgment, decree, order or statement of public policy of any court or governmental agency, board, bureau, body, department or authority, or (ii) will result in the creation or imposition of any penalty, charge, restriction, or material adverse effect upon the Company, then any such term or provision shall be null, void and of no effect.

Amendment. The Company may amend the provisions of this Agreement at any time; provided that an amendment that would materially adversely affect the Participant’s rights under this Agreement shall be subject to the written consent of the Participant. No course of conduct or failure or delay in enforcing the provisions of this Agreement shall affect the validity, binding effect or enforceability of this Agreement.

Acts of Misconduct. If Participant has allegedly committed an act of serious misconduct, including, but not limited to, embezzlement, fraud, dishonesty, unauthorized disclosure of trade secrets or confidential information, breach of fiduciary duty or nonpayment of an obligation owed to the

Disputes. The Administrator or its delegate shall finally and conclusively determine any disagreement concerning the Award.

Plan. The terms and provisions of the Plan are incorporated herein by reference, a copy of which has been provided or made available to the Participant. In the event of a conflict or inconsistency between the terms and provisions of the Plan and the provisions of this Agreement, the Plan shall govern and control.

Compliance with Section 409A of the Code. Notwithstanding any other provision of the Plan or this Agreement to the contrary, the Plan and this Agreement shall be construed or deemed to be amended as necessary to remain exempt from or comply with the requirements of Section 409A of the Code and to avoid the imposition of any additional or accelerated taxes or other penalties under Section 409A of the Code. The Committee, in its sole discretion, shall determine the requirements of Section 409A of the Code applicable to the Plan and this Agreement and shall interpret the terms of each consistently therewith. Under no circumstances, however, shall the Company, an Affiliate, or a subsidiary have any liability under the Plan or this Agreement for any taxes, penalties, or interest due on amounts paid or payable pursuant to the Plan and/or this Agreement, including any taxes, penalties, or interest imposed under Section 409A of the Code. In the event that it is reasonably determined by the Company that, as a result of the deferred compensation tax rules under Section 409A of the Code (and any related regulations or other pronouncements thereunder) (the “Deferred Compensation Tax Rules”), benefits that the Participant is entitled to receive under the terms of this Agreement are deferred compensation subject to tax under the Deferred Compensation Tax Rules, (i) the Participant shall not be considered to have terminated employment for purposes hereof until the Participant would be considered to have incurred a “separation from service” within the meaning of the Deferred Compensation Tax Rules and (ii) the Company shall, in lieu of providing such benefit when otherwise due under this Agreement, instead provide such benefit on the first day on which such provision would not result in the Participant incurring any tax liability under the Deferred Compensation Tax Rules; which day, if the Participant is a “specified employee” (within the meaning of the Deferred Compensation Tax Rules), shall, in the event the benefit to be provided is due to the Participant’s “separation from service” (within the meaning of the Deferred Compensation Tax Rules) with the Company and its subsidiaries, be the first day following the six-month period beginning on the date of such separation from service. Each amount to be paid or benefit to be provided under this Agreement shall be construed as a separately identified payment for purposes of the Deferred Compensation Tax Rules, and any payments described in this Agreement that are due within the “short term deferral period” as defined in the Deferred Compensation Tax Rules shall not be treated as deferred compensation unless applicable law requires otherwise.

Successors. The terms of this Agreement shall be binding upon and inure to the benefit of the Company, its successors and assigns, and the Participant and the beneficiaries, executors, administrators, heirs and successors of the Participant.

Entire Agreement. This Agreement and the Plan contain the entire agreement and understanding of the parties hereto with respect to the subject matter contained herein and supersede all prior communications, representations and negotiations in respect thereof; provided, however, that to the extent that the Participant has entered into an employment agreement, severance agreement or change
