In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a directors, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer, or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.</font></div><div><font><br></font></div><div style="position:relative;width:100%;height:18pt;"><div style="position:absolute;bottom:0;width:100%;"><div><font><br></font></div></div></div><hr style="page-break-after:always"><div style="height:9pt;width:100%;"><div><font><br></font></div></div><div style="text-align:center;"><font style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman',sans-serif;font-size:12pt;font-weight:700;line-height:120%;">SIGNATURES </font></div><div style="text-indent:36pt;margin-top:12pt;"><font style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman',sans-serif;font-size:12pt;font-weight:400;line-height:120%;">Pursuant to the requirements of the Securities Act of 1933, as amended, Entegris, Inc. certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this registration statement on Form S-8 to be signed on its behalf by the undersigned, thereunto duly authorized, in the Town of Billerica, Commonwealth of Massachusetts, on April 29, 2020. &#160;</font></div><div><table style="margin-left:auto;margin-right:auto;border-collapse:collapse;text-align:left;text-indent:0pt;display:inline-table;width:100.000%;"><tr><td style="width:1.0%;"></td><td style="width:50.083%;"></td><td style="width:1.0%;"></td><td style="width:1.0%;"></td><td style="width:3.608%;"></td><td style="width:1.0%;"></td><td style="width:0.1%;"></td><td style="width:1.723%;"></td><td style="width:0.1%;"></td><td style="width:1.0%;"></td><td style="width:38.386%;"></td><td style="width:1.0%;"></td></tr><tr><td colspan="3" style="background-color:rgb(255,255,255, 0.0);text-align:left;vertical-align:bottom;padding-left:1pt;padding-right:1pt;"></td><td colspan="9" style="padding-top:2px;padding-bottom:2px;background-color:rgb(255,255,255, 0.0);text-align:left;vertical-align:top;padding-left:1pt;padding-right:1pt;"><font style="font-size:12pt;font-weight:700;font-family:'Times New Roman',sans-serif;color:#000000;background-color:rgb(255,255,255, 0.0);">ENTEGRIS, INC.</font></td><td colspan="3" style="display:none;"></td><td colspan="3" style="display:none;"></td></tr><tr><td colspan="3" style="height:12pt;background-color:rgb(255,255,255, 0.0);text-align:left;vertical-align:bottom;padding-left:1pt;padding-right:1pt;"></td><td colspan="3" style="height:12pt;background-color:rgb(255,255,255, 0.0);text-align:left;vertical-align:bottom;padding-left:1pt;padding-right:1pt;"></td><td colspan="6" style="height:12pt;background-color:rgb(255,255,255, 0.0);text-align:left;vertical-align:bottom;padding-left:1pt;padding-right:1pt;"></td><td colspan="3" style="display:none;"></td></tr><tr><td colspan="3" style="background-color:rgb(255,255,255, 0.0);text-align:left;vertical-align:bottom;padding-left:1pt;padding-right:1pt;"></td><td colspan="3" style="padding-top:2px;padding-bottom:2px;background-color:rgb(255,255,255, 0.0);text-align:left;vertical-align:top;padding-left:1pt;padding-right:1pt;"><font style="font-size:12pt;font-weight:400;font-family:'Times New Roman',sans-serif;color:#000000;background-color:rgb(255,255,255, 0.0);">By</font></td><td colspan="3" style="padding-top:2px;padding-bottom:2px;background-color:rgb(255,255,255, 0.0);text-align:left;vertical-align:bottom;padding-left:1pt;padding-right:1pt;"><font style="font-size:12pt;font-weight:400;font-family:'Times New Roman',sans-serif;color:#000000;background-color:rgb(255,255,255, 0.0);">&#160;</font></td><td colspan="3" style="padding-top:2px;padding-bottom:2px;background-color:rgb(255,255,255, 0.0);text-align:left;vertical-align:top;padding-left:1pt;padding-right:1pt;"><font style="font-size:12pt;font-weight:400;font-family:'Times New Roman',sans-serif;color:#000000;background-color:rgb(255,255,255, 0.0);">&#47;s&#47;

Item 6. Indemnification of Officers and Directors.
The Registrant is incorporated under the laws of the State of Delaware. Section 145 ("Section 145") of the General Corporation Law of the State of Delaware, as the same exists or may hereafter be amended (the "DGCL"), inter alia, provides that a Delaware corporation may indemnify any persons who were, are or are threatened to be made parties to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of such corporation), by reason of the fact that such person is or was an officer, director, employee or agent of such corporation, or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided that such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the corporation's best interests and, with respect to any criminal action or proceeding, had no reasonable cause to believe that his or her conduct was illegal.
Section 145 further authorizes a corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or enterprise, against any liability asserted against him or her and incurred by him or her in any such capacity, arising out of his or her status as such, whether or not the corporation would otherwise have the power to indemnify him or her under Section 145.
The Registrant's certificate of incorporation provides that the Registrant's directors shall not be liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except to the extent that the exculpation from liabilities is not permitted under the DGCL as in effect at the time such liability is determined. The Registrant's certificate of incorporation provides that the corporation shall indemnify its directors to the full extent permitted by the laws of the State of Delaware. In addition, the Registrant's bylaws provide for indemnification of the registrant's officers and directors to the fullest extent permitted by applicable law.
All of the Registrant's directors and officers are covered by insurance policies maintained by the Registrant against specified liabilities for actions taken in their capacities as such, including liabilities under the Securities Act of 1933.
The Registrant has entered into indemnification agreements with its directors and certain of its executive officers providing for the indemnification of such director or executive officer, as applicable, to the extent legally permissible and the payment of expenses, including counsel fees reasonably incurred in connection with the defense or disposition of any action, suit or other proceeding in which such individual may be involved by reason of such individual being or having been a director or officer of the Registrant.

Item 9. Undertakings.
(a) The undersigned Registrant hereby undertakes:
(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:
(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;
(ii) To reflect in the prospectus any facts or events arising after the effective date of this Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this Registration Statement;
(iii) To include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to such information in this Registration Statement;
provided, however, that paragraphs (a) (1) (i) and (a) (1) (ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in this Registration Statement.
(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
(b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 that is
incorporated by reference in this Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein and the offering of such securities at that time shall be deemed to be initial bona fide offering thereof.
(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the provisions referred to in Item 6 hereof, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a directors, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer, or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.
