(b) RSUs. At the Effective Time, each outstanding time vesting restricted stock unit granted under the Versum Stock Plan (each, a “Versum RSU”) and under the Versum Prior Stock Plan (each, a “Prior Plan Versum RSU”) corresponding to shares of Versum Common Stock shall, in each case, be canceled and converted into that number of restricted stock units corresponding to shares of Entegris Common Stock (each, a “Replacement RSU”) equal to the product of (i) the number of shares of Versum Common Stock subject to such Versum RSU or Prior Plan Versum RSU immediately prior to the Effective Time and (ii) the Exchange Ratio. Each Replacement RSU shall (A) vest and settle on terms (including acceleration events) at least as favorable as were applicable to the corresponding Versum RSU or Prior Plan Versum RSU immediately prior to the Effective Time; and (B) vest in full to the extent the holder of a Replacement RSU is subject to a Covered Termination, with such Replacement RSU settled in shares of Entegris Common Stock as soon as practicable, but in no event later than five (5) Business Days following, such Covered Termination, or such later time as required to comply with Section 409A of the Code.

Following the Effective Time, each Replacement RSU and Substitute RSU shall accrue and be entitled to dividend equivalents to the same extent as the related Versum RSU, Prior Plan Versum RSU or Versum PSU.

(f) Versum Actions. At or prior to the Effective Time, Versum and the Versum Board (and the Versum Compensation Committee), as applicable, shall adopt any resolutions and take any actions that are necessary to effectuate the treatment of Versum Options, Versum RSUs, Prior Plan Versum RSUs, Versum PSUs, Versum DSUs and Versum Dividend Equivalents (collectively, the “Versum Equity Awards”) pursuant toSection 2.3(a) throughSection 2.3(e).

(h) Future Grants of Equity Awards. Notwithstanding anything inSection 2.3(a) throughSection 2.3(e) to the contrary, but subject toSection 7.1(a), to the extent the terms of any Versum Equity Award or Entegris Equity Award (i) granted on or after the date of this Agreement and not in violation of this Agreement or (ii) mutually agreed by the Parties and a holder of any Versum Equity Award (or Converted Award) or Entegris Equity Award expressly provide for treatment in connection with the occurrence of the Effective Time that is different from the treatment prescribed by thisSection 2.3, then in each case of clause (i) and (ii), the terms of such Versum Equity Award (or Converted Award) or Entegris Equity Award, as applicable or so agreed by the Parties and such holder, shall control (and the applicable provisions of thisSection 2.3 shall not apply).

(b) Prior to the Effective Time, Versum shall and, if Versum is unable to, Entegris shall cause the Combined Company as of the Effective Time to, obtain and fully pay the premium for “tail” insurance policies for the extension of (i) the directors’ and officers’ liability coverage of Versum’s existing directors’ and officers’ insurance policies, and (ii) Versum’s existing fiduciary liability insurance policies, in each case for a claims reporting or discovery period of six (6) years from and after the Effective Time (the “Tail Period”) from one or more insurance carriers with the same or better credit rating as Versum’s insurance carrier as of the date of this Agreement with respect to directors’ and officers’ liability insurance and fiduciary liability insurance (collectively, “D&O Insurance”) with terms, conditions, retentions and limits of liability that are at least as favorable to the insureds as Versum’s existing policies with respect to matters existing or occurring at or prior to the Effective Time (including in connection with this Agreement or the Transactions).

(c) Any Indemnified Party wishing to claim indemnification under thisSection 7.14, upon learning of any such Proceeding, shall promptly notify the Combined Company thereof in writing, but the failure to so notify shall not relieve the Combined Company of any liability it may have to such Indemnified Party except to the extent such failure materially prejudices the indemnifying party. In the event of any Proceeding: (i) the Combined Company shall have the right to assume the defense thereof (itbeingunderstood that by electing to assume the defense thereof, the Combined Company will not be deemed to have waived any right to object to the Indemnified Party’s entitlement to indemnification hereunder with respect thereto or assumed any liability with respect thereto), except that if the Combined Company elects not to assume such defense or legal counsel or the Indemnified Party advises that there are issues which raise conflicts of interest between the Combined Company and the Indemnified Party, the Indemnified Party may retain legal counsel satisfactory to them, and the Combined Company shall pay all reasonable and documented fees, costs and expenses of such legal counsel for the Indemnified Party promptly as statements therefor are received;provided,however, that the Combined Company shall be obligated pursuant to thisSection 7.14(c) to pay for only one firm of legal counsel for all Indemnified Parties in any jurisdiction unless the use of one legal counsel for such Indemnified Parties would present such legal counsel with a conflict of interest (provided that the fewest number of legal counsels necessary to avoid conflicts of interest shall be used); (ii) the Indemnified Parties shall cooperate in the defense of any such matter if the Combined Company elects to assume such defense, and the Combined Company shall cooperate in the defense of any such matter if the Combined Company elects not to assume such defense; (iii) the Indemnified Parties shall not be liable for any settlement effected without their prior written consent if the Combined Company elects to assume such defense and the Combined Company shall not be liable for any settlement effected without their prior written consent the Combined Company elects not to assume such defense; (iv) the Combined Company shall not have any obligation hereunder to any Indemnified Party if and when a court of competent jurisdiction shall ultimately determine, and such determination shall have become final, that the indemnified action of such Indemnified Party in the manner contemplated hereby is prohibited by applicable Law; and (v) all rights to indemnification in respect of any such Proceedings shall continue until final disposition of all such Proceedings.

(d) During the Tail Period, all rights to indemnification and exculpation from liabilities for acts or omissions occurring at or prior to the Effective Time and rights to advancement of expenses relating thereto now existing in favor of any Indemnified Party as provided in the Organizational Documents of Versum and its Subsidiaries or any indemnification agreement between such Indemnified Party and Versum or any of its Subsidiaries, in each case, as in effect on the date of this Agreement, shall survive the Transactions unchanged and shall not be amended, restated, repealed or otherwise modified in any manner that would adversely affect any right thereunder of any such Indemnified Party.

(e) If the Combined Company or any of their respective successors or assigns (i) shall consolidate with or merge into any other Person and shall not be the continuing or surviving Person of such consolidation or merger or (ii) shall transfer all or substantially all of its properties and assets to any Person, then, and in each such case, proper provisions shall be made so that the successors and assigns of the Combined Company shall assume all of the obligations set forth in thisSection 7.14.

7.16. Dividends. Versum and Entegris shall coordinate with each other to designate the same record and payment dates for any quarterly dividends or distributions declared in accordance with this Agreement in any calendar quarter in which the Closing Date might reasonably be expected to occur, so that holders of shares of Versum Common Stock do not receive dividends on both shares of Versum Common Stock and Entegris Common Stock received in the Merger in respect of any calendar quarter or fail to receive a dividend on either shares of Versum Common Stock or Entegris Common Stock received in the Merger in respect of any calendar quarter;provided, that the declaration and payment of any dividends on shares of Versum Common Stock or Entegris Common Stock shall be subject to applicable Law and the approval of the Versum Board or Entegris Board, as applicable.

7.17. Section 16 Matters. Versum and Entegris, and the Versum Board and the Entegris Board (or duly formed committees thereof consisting ofnon-employee directors (as such term is defined for the purposes ofRule 16b-3 promulgated under the Exchange Act)), shall, prior to the Effective Time, take all such actions as are reasonably necessary or appropriate to cause the Transactions and any other dispositions of equity securities of Versum or Entegris (including derivative securities) or acquisitions of shares of Entegris Common Stock (including derivative securities) in connection with the Transactions by any individual who is subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to Versum or Entegris or will become subject to such reporting requirements with respect to Entegris, to be exempt underRule 16b-3 promulgated under the Exchange Act, to the extent permitted by applicable Laws.

Each of Versum and Entegris shall give the other Party the opportunity to participate in the defense or settlement of any such stockholder litigation, and no such settlement shall be agreed to without the other Party’s prior written consent (which consent shall not be unreasonably withheld, conditioned or delayed).
