BY-LAWS

MATIV HOLDINGS, INC.

(as Amended and Restated on and through July 6, 2022)

CAPITAL STOCK

1. CERTIFICATES

Shares of stock of the corporation may be issued in uncertificated form and need not be represented by certificates, except to the extent that may be required by applicable law or as may be otherwise authorized by the Secretary or Assistant Secretary. Notwithstanding the foregoing, shares of stock represented by a certificate and issued and outstanding shall remain represented by a certificate until surrendered to the corporation. In the event that shares are represented by a certificate, the holder of each such certificated share shall be entitled to have a certificate in such form as the Board of Directors (“Board”) shall from time to time approve, signed by the Chairman of the Board, a Vice Chairman of the Board, the President or a Vice President and by the Treasurer, an Assistant Treasurer, the Secretary or an Assistant Secretary, certifying the number of shares owned by such stockholder. Any or all of the signatures on the certificate and the corporate seal may be facsimiles. In case any officer, transfer agent, or registrar who has signed or whose facsimile signature has been placed upon a certificate shall have ceased to be such officer, transfer agent or registrar before such certificate is issued, it may be issued by the corporation with the same effect as if he were such officer, transfer agent, or registrar at the date of issue. While the corporation is authorized to issue more than one class of stock or more than one series of any class, there shall be set forth on the face or back of each certificate issued a statement that the corporation will furnish without charge to each stockholder who so requests the powers, designations, preferences and relative participating, optional or other special rights of each class of stock or series thereof of the corporation and the qualifications, limitations or restrictions of such preferences and/or rights.

2. RECORD OWNERSHIP

The name and address of each stockholder, the number of shares held thereby, and the date of issuance thereof shall be recorded in the corporation’s books and records. The corporation shall be entitled to treat the holder of record of any share of stock as the holder in fact thereof, and accordingly shall not be bound to recognize any equitable or other claim to or interest in any share on the part of any other person, whether or not it shall have express or other notice thereof, except as required by law.

3. TRANSFER

Transfers of shares of stock represented by certificates shall be made on the books of the corporation only by direction of the person named in the certificate or his attorney, lawfully constituted in writing, and only upon the surrender for cancellation of the certificate therefore and a written assignment of the shares evidenced thereby. Transfers of uncertificated shares of stock shall be made on the books of the corporation upon receipt of proper transfer instructions from the

1

registered owner of the uncertificated shares, an instruction from an approved source duly authorized by such owner or from any lawyer lawfully constituted in writing. The corporation may impose such additional conditions to the transfer of its stock as may be necessary or appropriate for compliance with applicable law or to protect the corporation, a Transfer Agent or the Registrar from liability with respect to such transfer.

4. LOST CERTIFICATES

Any person claiming a stock certificate in lieu of one lost or destroyed shall give the corporation an affidavit as to his ownership of the certificate and of the facts which go to prove its loss or destruction. He shall also, if required by the Board, give the corporation a bond or other indemnification, in such form as may be approved by the Board, sufficient to indemnify the corporation against any claim that may be made against it on account of the alleged loss of the certificate or the issuance of a new certificate.

5. TRANSFER AGENT; REGISTRAR

The corporation shall maintain one or more transfer offices or agencies, each in charge of a transfer agent designated by the Board, where the shares of stock of the corporation shall be transferable. The corporation shall also maintain one or more registry offices, each in charge of a registrar designated by the Board, where such shares of stock shall be registered. The same entity may be both transfer agent and registrar.

6. RECORD DATE; CLOSING TRANSFER BOOKS

So that the corporation may determine the stockholders entitled to notice of or to vote at any meeting of stockholders, or any adjournment thereof, or entitled to express consent to corporate action in writing without a meeting as provided in Article VIII of the Certificate of Incorporation, or entitled to receive payment of any dividend or other distribution or allotment of rights, or entitled to exercise any rights in respect of any change, conversion or exchange of capital stock, or for the purpose of any other lawful action, the Board may fix a record date which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board and which record date shall not be more than sixty (60) days nor less than ten (10) days before the date of such meeting, nor more than ten (10) days from the date upon which the resolution fixing the record date is adopted by the Board in the case of a determination of the stockholders entitled to express consent to corporate action without a meeting, nor more than sixty days before any other action, and only such stockholders as shall be stockholders of record on the date so fixed shall be entitled to such notice of and to vote at such meeting, or to give such consent, or to receive such dividend or other distribution or allotment of rights, or to exercise such rights, or to take such other lawful action, as the case may be, notwithstanding any transfer of any stock on the books of the corporation after any such record date fixed as aforesaid. A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the Board may fix a new record date for the adjourned meeting.

To be timely, a stockholder’s notice to the Secretary must be delivered and received at the principal executive offices of the corporation not less than ninety (90) days nor more than one hundred twenty (120) days prior to the first anniversary date of the annual meeting of stockholders for the preceding year; provided, however, if and only if the annual meeting is not scheduled to held within a period that commences thirty (30) days before such anniversary date and ends thirty (30) days after such anniversary date (an annual meeting date outside such period being referred to herein as an “Other Meeting Date”), such Stockholder Notice shall be given in the manner provided herein by the later of the close of business on (i) the date ninety (90) days prior to such Other Meeting Date or (ii) the tenth day following the date such Other Annual Meeting Date is first publicly announced or disclosed.

5

To be in proper written form, a stockholder’s notice to the Secretary must set forth as to each matter such stockholder proposes to bring before the annual meeting of stockholders: (i) the text of the proposal to be presented, including the text of any resolutions to be proposed for consideration by stockholders; (ii) a brief written statement of the reasons why such stockholder favors the proposal; (iii) whether the stockholder is providing the notice at the request of a beneficial holder of shares, whether the stockholder or any such beneficial holder has any agreement, arrangement or understanding with, or has received any financial assistance, funding or other consideration from any other person with respect to the investment by the stockholder or the beneficial holder in the corporation or the matter such notice relates to, and the details thereof, including the name of such other person (for the purposes of this By-Law 15, the stockholder, any beneficial holder on whose behalf the notice is being delivered, and any persons with whom such agreement, arrangement or understanding exists or from whom such assistance has been obtained are hereinafter collectively referred to as “Interested Persons”); (iv) the name and address of all Interested Persons; (v) a complete listing of the record and beneficial ownership positions (including number or amount) of all equity securities and debt instruments, whether held in the form of loans or capital market instruments, of the corporation or any of its subsidiaries held by all Interested Persons; (vi) whether and the extent to which any hedging, derivative or other transaction is in place or has been entered into within the prior six months preceding the date of delivery of such notice by or for the benefit of any Interested Person with respect to the corporation or its subsidiaries or any of their respective securities, debt instruments or credit ratings, the effect or intent of which transaction is to give rise to gain or loss as a result of changes in the trading price of such securities or debt instruments or changes in the credit ratings for the corporation, its subsidiaries or any of their respective securities or debt instruments (or, more generally, changes in the perceived creditworthiness of the corporation or its subsidiaries), or to increase or decrease the voting power of such Interested Person, and if so, a summary of the material terms thereof; (vii) a brief description of the business proposed to be brought before the annual meeting of stockholders and the reasons for conducting such business at the annual meeting of stockholders; and (viii) a representation that such stockholder is a holder of record of stock of the corporation and intends to appear in person or by proxy at the annual meeting of stockholders to bring such business before the meeting. The corporation may require such stockholder to furnish such other information as may reasonably be required by the corporation in connection with such proposed business. Such notice shall be updated not later than ten (10) days after the record date for the determination of stockholders entitled to vote at the meeting to provide any material changes in the foregoing information as of the record date. As used herein, “beneficially owned” has the meaning provided in Rules 13d-3 and 13d-5 under the Securities Exchange Act of 1934.

No business shall be conducted at the annual meeting of stockholders except business (i) specified in the notice of annual meeting given by or at the direction of the Board, (ii) otherwise brought before the annual meeting by or at the direction of the Board or (iii) brought before the annual meeting in accordance with the procedures set forth in this By-Law 15 or By-Law 19; provided, however, that once business has been properly brought before the annual meeting of stockholders in accordance with such procedures, nothing in this By-Law 15 or By-Law 19 shall be deemed to preclude discussion by any stockholder of any such business. If the chairman of an annual meeting of stockholders determines that business was not properly brought before the meeting in accordance with the foregoing procedures, the chairman shall declare to the meeting that the business was not properly brought before the meeting and such business shall not be transacted.

Notwithstanding the foregoing provisions of this By-Law 15, unless otherwise required by law, if the stockholder (or a qualified representative of the stockholder) does not appear at the meeting of stockholders of the corporation to propose business, such proposed business shall not be transacted, notwithstanding that proxies in respect of such vote may have been received by the corporation.

For purposes of this By-Law 15 and By-Law 19, a matter shall be deemed to have been “publicly announced or disclosed” if such matter is disclosed in a press release reported by the Dow Jones News Service, Associated Press or comparable national news service or in a document publicly filed by the Corporation with the Securities and Exchange Commission.

In no event shall the postponement or adjournment of a stockholder meeting already publicly announced, or any announcement of such postponement or adjournment, commence a new period (or extend any time period) for the giving of notice as provided in this By-Law 15. This By-Law 15 shall not apply to stockholder proposals required to be included in the corporation’s proxy materials pursuant to Rule 14a-8 under the Exchange Act.

The person presiding at any meeting of stockholders, in addition to making any other determinations that may be appropriate to the conduct of the meeting, shall have the power and duty to determine whether notice of nominees and other matters proposed to be brought before a meeting has been duly given in the manner provided in this By-Law 15 or By-Law 19 and, if not so given, shall direct and declare at the meeting that such nominee or other matters are not properly before the meeting and shall not be considered.

BOARD OF DIRECTORS

16. NUMBER, ELECTION AND TERM OF OFFICE

Subject to By-Law 22A, the number of Directors of the corporation shall be fixed by resolution of the Board from time to time and, until otherwise determined, shall not be less than six (6) nor more than twelve (12); provided, however, that no decrease in the number of Directors shall have the effect of shortening the term of an incumbent director. Subject to By-Law 22A, the specific number of Directors constituting the entire Board shall be as authorized from time to time exclusively by the affirmative vote of a majority of the entire Board of Directors (as defined in Article X of the Certificate of Incorporation).

The Board shall be divided into three classes to be known as Class I, Class II and Class III, which shall be as nearly equal in number as possible. Except in case of death, resignation, disqualification, or removal, each director shall serve for a term ending on the date of the third annual meeting of stockholders following the annual meeting at which the director was elected; provided, however, in order to ensure balance among the three classes of Directors, to facilitate Director succession planning or for other similar purposes, the Board may determine that the term of any Director shall end on the date of the first or the second annual meeting of stockholders following an annual meeting at which the Director was elected; provided, further, that no such determination by the Board shall be effective without the express written consent of the Director whose term would be shortened thereby. A person elected as a director shall be deemed a Director

7

as of the time of such election. Despite the expiration of a director’s term, he or she shall continue to serve until his or her successor, if there is to be any, has been elected and has qualified. In the event of any increase or decrease in the authorized number of Directors, the newly created or eliminated directorships resulting from such an increase or decrease shall be apportioned among the three classes of Directors so that the three classes remain as nearly equal in size as possible, with such difference in the number of Directors in any two classes not to exceed one (1). Except as provided elsewhere in these By-Laws, the Directors shall be elected at each annual meeting of stockholders, or at a special meeting of stockholders called for purposes that include the election of Directors, by a plurality vote of shares present in person or represented by proxy at such meeting and entitled to vote and on the election of directors.

17. ELIGIBILITY

A person being a full-time executive employee of the corporation or any of its subsidiaries when first elected a Director of the corporation (an “employee-director”) shall not be eligible to serve as a Director when not an executive employee, whether by reason of resignation, retirement or other cause.

A person not an employee-director shall not be eligible for election or re-election as a Director of the corporation after his 72nd birthday; provided, however, that the Board may waive this age limit by unanimous decision

Any employee-director not eligible to serve as a Director by reason of the foregoing provision shall be eligible to serve as an advisory director, as hereinafter provided for in By-Law 18, until his 72nd birthday.

From the time that is one minute after the Effective Time (for purposes of these By-Laws, as defined in the Merger Agreement (as defined below)) until the date of the annual meeting of stockholders to be held in 2025 (or if an annual meeting of stockholders is not held in 2025, until December 31, 2025) (such period, the “Governance Period”) a person shall not be eligible to serve as a Director if such person was nominated by the Board or any committee thereof and such nomination was not made in accordance with By-Law 22A.

18. ADVISORY DIRECTORS

The Board may at any time appoint or reappoint as an advisory director any person eligible to serve as such under the second paragraph of By-Law 17 whose services as such will be, in the opinion of the Board, of value to the corporation. An advisory director shall be entitled to notice of and to attend and advise at, but not to vote at, meetings of the Board, and any committees thereof to which he shall be designated, and for his services may be paid, in the discretion of the Board, compensation and reimbursement of expenses on the same basis as if he were, a Director. The term of office of each advisory director shall terminate on the earlier of the date when he ceases to be eligible for such position under said paragraph of By-Law 17 or, subject to reappointment, the date of the first meeting of the Board after the annual meeting of stockholders next following his appointment.

19. NOMINATIONS

Subject to the rights of holders of any series of Preferred Stock or any other class of capital stock of the corporation (other than Common Stock) then outstanding, nominations for election of Directors may be made by (i) subject to By-Law 22A, the affirmative vote of a majority of the entire Board or (ii) by any stockholder of record entitled to vote generally in the election of Directors complying with this By-Law 19. Any stockholder of record entitled to vote generally in the election of Directors may nominate one or more persons for election as Directors at a meeting only if a written notice of such stockholder’s intent to make such nomination or nominations meeting the requirements described below, has been given, either by personal delivery or by United States mail, postage prepaid, to the Secretary of the corporation, and received by the corporation, not less than ninety (90) days nor more than one hundred twenty (120) days prior to the first anniversary date of the annual meeting of stockholders for the preceding year (the “Stockholder Notice”); provided, however, if and only if the annual meeting is not scheduled to held within a period that commences thirty (30) days before such anniversary date and ends thirty (30) days after such anniversary date (an annual meeting date outside such period being referred to herein as an “Other Meeting Date”), such Stockholder Notice shall be given in the manner provided herein by the later of the close of business on (i) the date ninety (90) days prior to such Other Meeting Date or (ii) the tenth day following the date such Other Annual Meeting Date is first publicly announced or disclosed. Each such notice to the Secretary shall set forth: (a) whether the stockholder is providing the notice at the request of a beneficial holder of shares, whether the stockholder, any beneficial holder or any nominee has any agreement, arrangement or understanding with, or has received any financial assistance, funding or other consideration from, any other person with respect to the investment by the stockholder or such beneficial holder in the corporation or the nomination or nominations, and the details thereof including the name of such other person (for the purposes of this By-Law 19, the stockholder, any beneficial holder on whose behalf the notice is being delivered, any nominees listed in the notice and any persons with whom such agreement, arrangement or understanding exists or from whom such assistance has been obtained are hereinafter collectively referred to as “Interested Persons”); (b) the name and address of record of all Interested Persons; (c) a complete listing of the record and beneficial ownership positions (including number or amount) of all equity securities and debt instruments, whether held in the form of loans or capital market instruments, of the corporation or any of its subsidiaries held by all Interested Persons; (d) whether and the extent to which any hedging, derivative or other transaction is in place or has been entered into within the prior six (6) months preceding the date of delivery of such notice by or for the benefit of any Interested Person with respect to the corporation or its subsidiaries or any of their respective securities, debt instruments or credit ratings, the effect or intent of which transaction is to give rise to gain or loss as a result of changes in the trading price of such securities or debt instruments or changes in the credit ratings for the corporation, its subsidiaries or any of their respective securities or debt instruments (or, more generally, changes in the perceived creditworthiness of the corporation or its subsidiaries), or to increase or decrease the voting power of such Interested Person, and if so, a summary of the material terms thereof; (e) a representation that the stockholder is a holder of record of shares of the corporation entitled to vote at such meeting and intends to appear in person or by proxy at the meeting to nominate the person or persons specified in the notice; (f) the name, age, business and residence addresses, and principal occupation or employment of each nominee; (g) whether each nominee is eligible for consideration as an independent Director under the relevant standards contemplated by Item 407(a) of Regulation S-K; (h) such other information regarding each nominee proposed by such stockholder as would be required to be included in a proxy statement filed pursuant to the proxy rules of the Securities and Exchange Commission; and (i) the signed consent of each nominee to serve as a Director of the corporation if so elected. The corporation may require any proposed nominee to furnish such other information as may reasonably be required by the corporation to determine the eligibility of such proposed nominee to serve as a

9

Director of the corporation or to be considered “independent” as a Director or as a member of the audit or other committee of the Board under the various rules and standards applicable to the corporation. The presiding officer of the meeting may, if the facts warrant, determine that a nomination was not made in accordance with the foregoing procedure, and if he should so determine, he shall so declare to the meeting and the defective nomination shall be disregarded. Such notice shall be updated not later than ten (10) days after the record date for the determination of stockholders entitled to vote at the meeting to provide any material changes in the foregoing information as of the record date. As used herein, “beneficially owned” has the meaning provided in Rules 13d-3 and 13d-5 under the Securities Exchange Act of 1934.

Notwithstanding anything in this Article 19 to the contrary, in the event that the number of Directors to be elected to the Board is increased and either all of the nominees for Director or the size of the increased Board is not publicly announced or disclosed by the corporation at least 100 days prior to the first anniversary of the preceding year’s annual meeting, a Stockholder Notice shall also be considered timely hereunder, but only with respect to nominees for any new positions created by such increase, if it shall be delivered to the Secretary of the corporation at the principal executive office of the corporation not later than the close of business on the tenth day following the first date all of such nominees or the size of the increased Board shall have been publicly announced or disclosed.

Only such matters shall be properly brought before a special meeting of stockholders as shall have been brought before the meeting pursuant to the corporation’s notice of meeting. In the event the corporation calls a special meeting of stockholders for the purpose of electing one or more directors to the Board, any stockholder may nominate a person or persons (as the case may be), for election to such position(s) as specified in the corporation’s notice of meeting, if the Stockholder Notice required by this Article 19 hereof shall be delivered to the Secretary of the corporation at the principal executive office of the corporation not later than the close of business on the tenth day following the day on which the date of the special meeting and of the nominees proposed by the Board to be elected at such meeting is publicly announced or disclosed.

Notwithstanding the foregoing provisions of this By-Law 19, unless otherwise required by law, if the stockholder (or a qualified representative of the stockholder) does not appear at the annual or special meeting of stockholders of the corporation to present a nomination, such nomination shall be disregarded, notwithstanding that proxies in respect of such vote may have been received by the corporation.

In no event shall the postponement or adjournment of a stockholder meeting already publicly announced, or any announcement of such postponement or adjournment, commence a new period (or extend any time period) for the giving of notice as provided in this By-Law 19.

20. VACANCIES

Subject to the rights of the holders of any series of Preferred Stock or any other class of capital stock of the corporation (other than the Common Stock) then outstanding, any vacancies in the Board for any reason and any newly created Directorships resulting by reason of any increase in the number of Directors may, if occurring prior to the expiration of the term of office in which such vacancy or increase occurs, be filled only by the Board, acting by the affirmative vote of a majority of the remaining Directors then in office, although less than a quorum, and any Directors so elected shall hold office until the next election of the Class to which such Director was appointed and until their successors are elected and qualified or the earlier of such Director’s death, resignation or removal; provided, however, that during the Governance Period, the power of Directors to fill vacancies shall be subject to By-Law 22A

22. RESIGNATION

A Director may resign at any time by giving written notice to the corporation, addressed to the Chief Executive Officer or the Secretary.

(i) indemnify any person who was or is a party or is threatened to be made a party 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 the corporation) by reason of the fact that he is or was a director or officer of the corporation, or is or was serving at the request of the corporation as a director or officer of another corporation, or in the case of an officer or director of the corporation is or was serving as an employee or agent of a partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that his conduct was unlawful; and

21

(ii) indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact he is or was a director or officer of the corporation, or is or was serving at the request of the corporation as a director or officer of another corporation, or in the case of an officer or director of the corporation is or was serving as an employee or agent of a partnership, joint venture, trust or other enterprise against expenses (including attorneys’ fees) actually and reasonably incurred by him in connection with the defense or settlement of such action or suit if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

The corporation shall be required to indemnify an indemnitee in connection with a proceeding (or part thereof) initiated by such indemnitee against the corporation or any of its Directors or employees only if the initiation of such proceeding (or part thereof) by the indemnitee was authorized by the Board. Notwithstanding the foregoing, the corporation shall be required to indemnify an indemnitee in connection with a proceeding seeking to enforce rights to indemnification without the authorization of the Board to the extent that such proceeding is successful on the merits. To the extent that a director or officer of the corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in subsections (i) and (ii), or in defense of any claim, issue or matter therein, he shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by him in connection therewith.

Any indemnification under subsections (i) and (ii) (unless ordered by a court) shall be made by the corporation only as authorized in the specific case upon a determination that indemnification of the director or officer is proper in the circumstances because he has met the applicable standard of conduct set forth in subsections (i) and (ii). Such determination shall be made (1) by a majority vote of the Directors who were not parties to such action, suit or proceedings, even though less than a quorum; or (2) if there are no such Directors, or if such Directors so direct, by independent legal counsel in a written opinion; or (3) by the stockholders.

Expenses (including attorneys’ fees) incurred in defending any civil, criminal, administrative or investigative action, suit or proceeding shall be paid by the corporation in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of the director or officer to repay such amount if it shall ultimately be determined that he is not entitled to be indemnified by the corporation as authorized in this By-Law.

The indemnification and advancement of expenses provided by, or granted pursuant to, the other paragraphs of this By-Law shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any by-law, agreement, vote of stockholders or disinterested Directors or otherwise, both as to action in his official capacity and as to action in another capacity while holding such office, and shall continue as to a person who has ceased to be a director or officer and shall inure to the benefit of the heirs, executors and administrators of such a person.

22

The corporation’s obligation, if any, to indemnify any person who was or is serving at its request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, enterprise or nonprofit entity shall be reduced by any amount such person may collect as indemnification from such other corporation, partnership, joint venture, trust, enterprise or nonprofit entity.

The Board may authorize and direct that insurance be purchased and maintained on behalf of any person who is or was a director or officer of the corporation, or is or was serving at the request of the corporation as a director or officer of another corporation, or in the case of an officer or director of the corporation, is or was serving as an employee or agent of a partnership, joint venture, trust or other enterprise against any liability asserted against him and incurred by him in such capacity, or arising out of his status as such, whether or not the corporation would have the power to indemnify him against such liability under the provisions of this By-Law.

Each director, each member of any committee designated by the Board, and each officer, shall, in the performance of his duties, be fully protected in relying in good faith upon the records of the corporation and upon such information, opinion, reports or statements presented to the corporation by any of the corporation’s officers or employees, or committees of the Board, or by any other person as to matters the director, member or officer reasonably believes are within such other person’s professional or expert competence and who has been selected with reasonable care by or on behalf of the corporation.

54. INSPECTION OF BOOKS

The Directors shall determine from time to time whether, and, to what extent and at what times and places and under what conditions and regulations the accounts and other books and records of the corporation (except such as may by statute be specifically open to inspection) or any of them, shall be open to the inspection of the stockholders, and the stockholders’ rights in this respect are and shall be restricted and limited accordingly.

55. TRANSACTIONS WITH THE CORPORATION

No contract or transaction between the corporation and one or more of its Directors or officers, or between the corporation and any other corporation, partnership, association, or other organization in which one or more of its Directors or officers are directors or officers, or have a financial interest, shall be void or voidable solely for this reason, or solely because the Director or officer is present at or participates in the meeting of the Board or committee thereof which authorizes the contract or transaction, or solely because his or their votes are counted for such purposes, if:

(i) the material facts as to his relationship or interest and as to the contract or transaction are disclosed or are known to the Board or the committee, and the Board or committee in good faith authorizes the contract or transaction by the affirmative votes of a majority of the disinterested Directors, even though the disinterested Directors be less than a quorum; or

23

(ii) the material facts as to his relationship or interest and as to the contract or transaction are disclosed or are known to the stockholders entitled to vote thereon, and the contract or transaction is specifically approved in good faith by vote of the stockholders; or

(iii) the contract or transaction is fair as to the corporation as of the time it is authorized, approved or ratified, by the Board, a committee thereof, or the stockholders.

Common or interested Directors may be counted in determining the presence of a quorum at a meeting of the Board or of a committee which authorizes the contract or transaction.

No other contract or transaction in which a director or officer has an interest and which may, under law, be authorized, approved or ratified by the Board, a committee thereof, or the stockholders shall be void or voidable if authorized, approved or ratified by the body which under law may authorize, approve or ratify such contract or transaction.

56. RATIFICATION

Any transaction questioned on the ground of lack of authority, defective or execution, adverse interest of director, officer, or stockholder, nondisclosure, miscomputation, or the application of improper principles or practices of accounting may be ratified before or after judgment, by the Board or by the stockholders in case less than a quorum of Directors is qualified; and, if so ratified, shall have the same force and effect as if the questioned transaction had been originally duly authorized, and said ratification shall be binding upon the corporation and its stockholders and shall constitute a bar to any claim or execution of any judgment in respect to such questioned transaction.

57. VOTING OF STOCKS

Unless otherwise ordered by the Board, any one of the Chief Executive Officer, the Chairman of the Board, the President, any Vice Chairman of the Board, any Executive Vice President or any Senior Vice President shall have full power and authority, on behalf of the corporation, to consent to or approve of any action by, and to attend, act and vote at any meeting of stockholders of, any company in which the corporation may hold shares of stock, and in giving such consent or approval or at any such meeting shall possess and may exercise any and all rights and powers incident to the ownership of such shares and which as the holder thereof, the corporation might possess and exercise if personally present, and may exercise such power and authority through the execution of proxies or may delegate such power and authority to any other officer, agent or employee of the corporation.

58. WAIVER OF NOTICE

Whenever any notice is required to be given, a waiver thereof in writing signed by, or electronic transmission by (if applicable), the person or persons entitled to the notice, whether before or after the time stated therein, shall be deemed equivalent thereto.

24

The attendance of a stockholder at any stockholder meeting shall constitute a waiver of notice at such meeting, except where the stockholder attends the stockholder meeting for the express purpose of objecting at the beginning of the meeting to the transaction of any business because the meeting is not lawfully called or convened. Neither the business to be transacted at, nor the purpose of, any annual or special meeting of stockholders need be specified in any waiver of notice unless so required by law.

The attendance of a Director at any meeting of the Board shall constitute a waiver of notice of such meeting, except where the Director attends the meeting for the express purpose of objecting at the beginning of the meeting to the transaction of any business because the meeting is not lawfully called or convened. Neither the business to be transacted at, nor the purpose of, any regular or special meeting of the Board need be specified in any notice or waiver of notice of such meeting unless so required by law.

59. DISPENSING WITH NOTICE

No notice need be given to any person with whom communication is made unlawful by any law of the United States or any rule, regulation, proclamation or executive order issued under any such law.

60. FORUM FOR ADJUDICATION OF DISPUTES

Unless the corporation consents in writing to the selection of an alternative forum, the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of the corporation, (ii) any action asserting a claim of breach of a fiduciary duty owed by any Director, officer or other employee of the corporation to the corporation or the corporation’s stockholders, (iii) any action asserting a claim against the corporation or any of its directors, officers or other employees arising pursuant to any provision of the Delaware General Corporation Law, the Certificate of Incorporation or these By-Laws (in each case, as may be amended from time to time), or (iv) any action asserting a claim against the corporation or any of its directors, officers or other employees governed by the internal affairs doctrine of the State of Delaware shall be the Court of Chancery of the State of Delaware or another state court located within the State of Delaware (or, if no state court located within the State of Delaware has jurisdiction, the federal district court for the District of Delaware).

61. AMENDMENTS

Subject to the provisions of the Certificate of Incorporation, these By-Laws may be altered, amended or repealed by the stockholders or by the Board; provided, however, that during the Governance Period, any amendment to the By-Laws effected by the Board that alters, amends or repeals any By-Law amendments that became effective as of the effectiveness of the resolutions under the heading “Immediately Effective Resolutions” in a unanimous written consent adopted by the Board on July 6, 2022, including this By-Law 61 (the “Effective Time Amendments”), shall require the approval of 75% of the entire Board of Directors (as defined in Article X of the Certificate of Incorporation).

25

62. GOVERNANCE PERIOD AMENDMENTS

As of the end of the Governance Period, the Effective Time Amendments shall be of no further force and effect. In case any provision in the Effective Time Amendments is held to be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions of the Effective Time Amendments shall not in any way be affected or impaired thereby and such provision shall be ineffective only to the extent of such invalidity, illegality or unenforceability.

The following emergency provisions are excerpted

from § 110 Delaware General Corporation Law

The Board, either before or during any such emergency, may provide, and from time to time modify, lines of succession in the event that during such emergency any or all officers or agents of the corporation shall for any reason be rendered incapable of discharging their duties.

The Board, either before or during any such emergency, may, effective in the emergency, change the head office or designate several alternative head offices or regional offices, or authorize the officers so to do.

No officer, director or employee acting in accordance with any emergency by-laws shall be liable except for willful misconduct.

To the extent not inconsistent with any emergency by-laws so adopted, the by-laws of the corporation shall remain in effect during any emergency and upon its termination the emergency by-laws shall cease to be operative.

Unless otherwise provided in emergency by-laws, notice of any meeting of the Board during such an emergency may be given only to such of the directors as it may be feasible to reach at the time and by such means as may be feasible at the time, including publication or radio.

To the extent required to constitute a quorum at any meeting of the Board during such an emergency, the officers of the corporation who are present shall, unless otherwise provided in emergency by-laws, be deemed, in order of rank and within the same rank in order of seniority, directors for such meeting.
