Stockholders

Section 1.1. Annual Meetings. An annual meeting of stockholders shall be held for the election of directors at such date, time and place either within or without the State of Delaware, or may not be held at any place, but may instead be held solely by means of remote communication, as may be designated by the Board of Directors (the “Board”) from time to time. Any other proper business may be transacted at the annual meeting.

Section 1.2. Special Meetings. Special meetings of stockholders may be called at any time by the Chairperson of the Board, if any, the Vice Chairperson of the Board, if any, the President or the Board, to be held at such date, time and place either within or without the State of Delaware, or may not be held at any place, but may instead be held by means of remote communication, as may be stated in the notice of the meeting. A special meeting of stockholders shall be called by the Secretary upon the written request, stating the purpose of the meeting, of stockholders who together own of record a majority of the outstanding shares of each class of stock entitled to vote at such meeting.

Section 1.3. Notice of Meetings. Whenever stockholders are required or permitted to take any action at a meeting, a written notice of the meeting shall be given which shall state the place, if any, date and hour of the meeting, the means of remote communications, if any, by which stockholders and proxyholders may be deemed to be present in person and vote at such meeting, the record date for determining the stockholders entitled to vote at the meeting, if such date is different from the record date for determining stockholders entitled to notice of the meeting, and, in the case of a special meeting, the purpose or purposes for which the meeting is called. Unless otherwise provided by law, the written notice of any meeting shall be given not less than ten nor more than sixty days before the date of the meeting to each stockholder entitled to vote at such meeting as of the record date for determining the stockholders entitled to notice of the meeting. If mailed, such notice shall be deemed to be given when deposited in the United States mail, postage prepaid, directed to the stockholder at such stockholder’s address as it appears on the records of Versum Materials, Inc. (the “Corporation”). In addition, if stockholders have consented to receive notices by a form of electronic transmission, then such notice, by facsimile telecommunication, or by electronic mail, shall be deemed to be given when directed to a number or an electronic mail address, respectively, at which the stockholder has consented to receive notice. If such notice is transmitted by a posting on an electronic network together with separate notice to the stockholder of such specific posting, such notice shall be deemed to be given upon the later of (i) such posting, and (ii) the giving of such separate notice. If such notice is transmitted by any other form of electronic transmission, such notice shall be deemed to be given when directed to the stockholder. Notice shall be deemed to have been

given to all stockholders of record who share an address if notice is given in accordance with the “householding” rules set forth in Section 233 of the General Corporation Law of the State of Delaware (the “DGCL”). For purposes of these bylaws, “electronic transmission” means any form of communication, not directly involving the physical transmission of paper, including the use of, or participation in, one or more electronic networks or databases (including one or more distributed electronic networks or databases), that creates a record that may be retained, retrieved and reviewed by a recipient thereof, and that may be directly reproduced in paper form by such recipient through an automated process.

Section 1.4. Adjournments. Any meeting of stockholders, annual or special, may be adjourned from time to time, to reconvene at the same or some other place, and notice need not be given of any such adjourned meeting if the time, place, if any, thereof, and the means of remote communications, if any, thereof are announced at the meeting at which the adjournment is taken. At the adjourned meeting the Corporation may transact any business which might have been transacted at the original meeting. If the adjournment is for more than thirty days, or if after the adjournment a new record date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting. In addition, subject to applicable law, any meeting of stockholders of the Corporation, annual or special, may be postponed by the Board at any time before such meeting has been convened, and such postponement shall be considered a cancellation of the originally noticed meeting. Notice of the postponed meeting shall be given to each stockholder of the Corporation of record entitled to vote at the meeting.

Section 1.5. Quorum. At each meeting of stockholders, except where otherwise provided by law or the certificate of incorporation or these bylaws, the holders of a majority of the outstanding shares of stock entitled to vote on a matter at the meeting, present in person or represented by proxy, shall constitute a quorum. A quorum, once established, shall not be broken by the withdrawal of enough votes to leave less than a quorum. In the absence of a quorum of the holders of any class of stock entitled to vote on a matter, either (i) the holders of such class so present or represented may, by majority vote, adjourn the meeting of such class from time to time in the manner provided by Section 1.4 of these bylaws until a quorum of such class shall be so present or represented or (ii) the chairperson of the meeting may on his or her own motion adjourn the meeting from time to time in the manner provided by Section 1.4 of these bylaws until a quorum of such class shall be so present and represented without the approval of the stockholders who are present in person or represented by proxy and entitled to vote, without notice other than announcement at the meeting.

Section 1.6. Organization. Meetings of stockholders shall be presided over by the Chairperson of the Board, if any, or in the absence of the Chairperson of the Board by the Vice Chairperson of the Board, if any, or in the absence of the Vice Chairperson of the Board by the President, or in the absence of the President by a Vice President, or in the absence of the foregoing persons by a chairperson designated by the Board, or in the absence of such designation by a chairperson chosen at the meeting. The Secretary or in the absence of the Secretary an Assistant Secretary, shall act as secretary of the meeting, but in the absence of the Secretary and any Assistant Secretary the chairperson of the meeting may appoint any person to act as secretary of the meeting. The order of business at each such meeting shall be as

determined by the chairperson of the meeting. The chairperson of the meeting shall have the right and the authority to prescribe such rules, regulations and procedures and to do all such acts and things as are necessary or desirable for the proper conduct of the meeting, including, without limitation, the establishment of procedures for the maintenance of order and safety, limitations on the time allotted to questions or comments on the affairs of the Corporation, restrictions on entry to such meeting after the time prescribed for the commencement thereof and the opening and closing of the voting polls.

Section 1.7. Voting; Proxies. Unless otherwise provided in the certificate of incorporation, each stockholder entitled to vote at any meeting of stockholders shall be entitled to one vote for each share of stock held by such stockholder which has voting power upon the matter in question. Each stockholder entitled to vote at a meeting of stockholders or to express consent or dissent to corporate action in writing without a meeting may authorize another person or persons to act for such stockholder by proxy, but no such proxy shall be voted or acted upon after three years from its date, unless the proxy provides for a longer period. A duly executed proxy shall be irrevocable if it states that it is irrevocable and if, and only as long as, it is coupled with an interest sufficient in law to support an irrevocable power, regardless of whether the interest with which it is coupled is an interest in the stock itself or an interest in the Corporation generally. A stockholder may revoke any proxy which is not irrevocable by attending the meeting and voting in person or by filing an instrument in writing revoking the proxy or another duly executed proxy bearing a later date with the Secretary of the Corporation. Voting at meetings of stockholders need not be by written ballot and need not be conducted by inspectors unless the holders of a majority of the outstanding shares of all classes of stock entitled to vote thereon present in person or represented by proxy at such meeting shall so determine. Directors shall be elected by a plurality of the votes of the shares present in person or represented by proxy at the meeting and entitled to vote on the election of directors. In all other matters, unless otherwise provided by law or by the certificate of incorporation or these bylaws, the affirmative vote of the holders of a majority of the shares present in person or represented by proxy at the meeting and entitled to vote on the subject matter shall be the act of the stockholders.

Section 1.8. Fixing Date for Determination of Stockholders of Record. In order that the Corporation may determine the stockholders entitled to notice of any meeting of stockholders or any adjournment thereof, 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 nor less than ten days before the date of such meeting. If the Board so fixes a date, such date shall also be the record date for determining the stockholders entitled to vote at such meeting unless the Board determines, at the time it fixes such record date, that a later date on or before the date of the meeting shall be the date for making such determination. If no record date is fixed by the Board, the record date for determining stockholders entitled to notice of and to vote at a meeting of stockholders shall be at the close of business on the day next preceding the day on which notice is given, or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held. 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 or, if necessary, any postponement of the meeting effected pursuant to Section 1.4 of these bylaws; provided, however, that the Board may fix a new record date for determination of stockholders entitled to vote at the adjourned

meeting, and in such case shall also fix the record date for stockholders entitled to notice of such adjourned meeting the same or an earlier date as that fixed for determination of stockholders entitled to vote in accordance with the foregoing provisions of this Section 1.8 at the adjourned meeting.

In order that the Corporation may determine the stockholders entitled to consent to corporate action in writing without a meeting, 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 date shall not be more than ten days after the date upon which the resolution fixing the record date is adopted by the Board. If no record date has been fixed by the Board, the record date for determining stockholders entitled to consent to corporate action in writing without a meeting, when no prior action by the Board is required by law, shall be the first date on which a signed written consent setting forth the action taken or proposed to be taken is delivered to the Corporation by delivery to its registered office in the State of Delaware, its principal place of business, or an officer or agent of the Corporation having custody of the book in which proceedings of meetings of stockholders are recorded. Delivery made to the Corporation’s registered office shall be by hand or by certified or registered mail, return receipt requested. If no record date has been fixed by the Board and prior action by the Board is required by law, the record date for determining stockholders entitled to consent to corporate action in writing without a meeting shall be at the close of business on the day on which the Board adopts the resolution taking such prior action.

In order that the Corporation may determine the stockholders entitled to receive payment of any dividend or other distribution or allotment of any rights or the stockholders entitled to exercise any rights in respect of any change, conversion or exchange of 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, and which record date shall be not more than sixty days prior to such action. If no record date is fixed, the record date for determining stockholders for any such purpose shall be at the close of business on the day on which the Board adopts the resolution relating thereto.

Section 1.9. List of Stockholders Entitled to Vote. The Secretary, or such other officer of the Corporation who has charge of the stock ledger of the Corporation, shall prepare and make, at least ten days before every meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting; provided, however, if the record date for determining the stockholders entitled to vote is less than ten days before the meeting date, the list shall reflect the stockholders entitled to vote as of the tenth day before the meeting date, arranged in alphabetical order, and showing the address of each stockholder and the number of shares registered in the name of each stockholder. Nothing in this Section shall require the Corporation to include electronic mail addresses or other electronic content information on such list. Such list shall be open to the examination of any stockholder for any purpose germane to the meeting for a period of at least ten days prior to the meeting: (i) on a reasonably accessible electronic network, provided that the information required to gain access to such list is provided with the notice of the meeting, or (ii) during ordinary business hours, at the principal place of business of the Corporation. In the event that the Corporation determines to make the list available on an electronic network, the Corporation may take reasonable steps to ensure that

such information is available only to stockholders of the Corporation. If the meeting is to be held at a place, then a list of stockholders entitled to vote at the meeting shall be produced and kept at the time and place of the meeting during the whole time thereof and may be examined by any stockholder who is present. If the meeting is to be held solely by means of remote communication, then such list shall also be open to the examination of any stockholder during the whole time of the meeting on a reasonably accessible electronic network, and the information required to access such list shall be provided with the notice of the meeting.

Section 1.10. Consent of Stockholders in Lieu of Meeting. Unless otherwise provided in the certificate of incorporation or by law, any action required by law to be taken at any annual or special meeting of stockholders of the Corporation, or any action which may be taken at any annual or special meeting of such stockholders, may be taken without a meeting, without prior notice and without a vote, if a consent or consents in writing, setting forth the action so taken, shall be signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted and shall be delivered to the Corporation by delivery to (a) its registered office in the State of Delaware by hand or by certified mail or registered mail, return receipt requested, (b) its principal place of business, or (c) an officer or agent of the Corporation having custody of the book in which proceedings of meetings of stockholders are recorded. Every written consent shall bear the date of signature of each stockholder who signs the consent and no written consent shall be effective to take the corporate action referred to therein unless, within sixty days of the earliest dated consent delivered in the manner required by this bylaw to the Corporation, written consents signed by a sufficient number of holders to take action are delivered to the Corporation by delivery to (a) its registered office in the State of Delaware by hand or by certified or registered mail, return receipt requested, (b) its principal place of business, or (c) an officer or agent of the Corporation having custody of the book in which proceedings of meetings of stockholders are recorded.

Any copy, facsimile or other reliable reproduction of a consent in writing may be substituted or used in lieu of the original writing for any and all purposes for which the original writing could be used, provided that such copy, facsimile or other reproduction shall be a complete reproduction of the entire original writing.

Prompt notice of the taking of the corporate action without a meeting by less than unanimous written consent shall be given to those stockholders who have not consented in writing and who, if the action had been taken at a meeting, would have been entitled to notice of the meeting if the record date for notice of such meeting had been the date that written consents signed by a sufficient number of stockholders to take the action were delivered to the Corporation as provided in this Section 1.10.

Unless otherwise specified therein no acceptance of such resignation shall be necessary to make it effective. Any director or the entire Board may be removed, with or without cause, by the holders of a majority of the shares then entitled to vote at an election of directors. Unless otherwise provided in the certificate of incorporation or these bylaws, vacancies and newly created directorships resulting from any increase in the authorized number of directors elected by all of the stockholders having the right to vote as a single class or from any other cause may be filled by a majority of the directors then in office, although less than a quorum, or by the sole remaining director. Any director elected or appointed to fill a vacancy shall hold office until his or her successor is elected and qualified or until his or her earlier death, disqualification, resignation or removal.

Section 2.3. Regular Meetings. Regular meetings of the Board may be held at such places within or without the State of Delaware and at such times as the Board may from time to time determine, and if so determined notice thereof need not be given.

Section 2.6. Quorum; Vote Required for Action. At all meetings of the Board a majority of the then appointed or then elected Board shall constitute a quorum for the transaction of business. The vote of a majority of the directors present at a meeting at which a quorum is present shall be the act of the Board unless the certificate of incorporation or these bylaws shall require a vote of a greater number. In case at any meeting of the Board a quorum shall not be present, the members of the Board present may adjourn the meeting from time to time until a quorum shall be present.

Section 2.7. Organization. Meetings of the Board shall be presided over by the Chairperson of the Board, if any, or in the absence of the Chairperson of the Board by the Vice Chairperson of the Board, if any, or in the absence of the Vice Chairperson of the Board by the President, or in their absence by a chairperson chosen at the meeting. The Secretary, or in the absence of the Secretary an Assistant Secretary, shall act as secretary of the meeting, but in the absence of the Secretary and any Assistant Secretary the chairperson of the meeting may appoint any person to act as secretary of the meeting.

Section 2.8. Action by Directors Without a Meeting. Unless otherwise restricted by the certificate of incorporation or these bylaws, any action required or permitted to be taken at any meeting of the Board, or of any committee thereof, may be taken without a meeting if all members of the Board or of such committee, as the case may be, consent thereto in writing or by electronic transmission, and the writing or writings or electronic transmission or transmissions are filed with the minutes of proceedings of the Board or committee.

Section 2.9. Compensation of Directors. No director serving on the Board or any committee thereof will receive any compensation therefor from the Corporation; provided that nothing herein shall be construed to preclude any director from serving the Corporation in any other capacity and receiving compensation therefor.

Section 3.1. Committees. The Board may designate one or more committees, each committee to consist of one or more of the directors of the Corporation. The Board may designate one or more directors as alternate members of any committee, who may replace any absent or disqualified member at any meeting of the committee. In the absence or disqualification of a member of a committee, the member or members thereof present at any meeting and not disqualified from voting, whether or not such member or members constitute a quorum, may unanimously appoint another member of the Board to act at the meeting in the place of any such absent or disqualified member. Any such committee, to the extent provided in the resolution of the Board or in these bylaws, shall have and may exercise all the powers and authority of the Board in the management of the business and affairs of the Corporation, and may authorize the seal of the Corporation to be affixed to all papers which may require it; but no such committee shall have the power or authority in reference to the following matters: (i) approving or adopting, or recommending to the stockholders, any action or matter (other than the election or removal of directors) expressly required by law to be submitted to stockholders for approval, (ii) adopting, amending or repealing these bylaws or (iii) indemnifying directors.

Section 3.2. Committee Rules. Unless the Board otherwise provides, each committee designated by the Board may adopt, amend and repeal rules for the conduct of its business.

Section 4.1. Officers; Election. As soon as practicable after the annual meeting of stockholders in each year, the Board shall elect a President and a Secretary, and it may, if it so determines, elect from among its members a Chairperson of the Board and a Vice Chairperson of the Board. The Board may also elect one or more Vice Presidents, one or more Assistant Vice Presidents, one or more Assistant Secretaries, a Treasurer and one or more Assistant Treasurers and such other officers as the Board may deem desirable or appropriate and may give any of them such further designations or alternate titles as it considers desirable. Any number of offices may be held by the same person unless the certificate of incorporation or these bylaws otherwise provide.

Section 4.2. Term of Office; Resignation; Removal; Vacancies. Unless otherwise provided in the resolution of the Board electing any officer, each officer shall hold office until his or her successor is elected and qualified or until his or her earlier resignation or removal.

Such resignation shall take effect at the time it is delivered unless the resignation specifies a later effective date or an effective date determined upon the happening of an event or events. Unless otherwise specified therein no acceptance of such resignation shall be necessary to make it effective. The Board may remove any officer with or without cause at any time. Any such removal shall be without prejudice to the contractual rights of such officer, if any, with the Corporation, but the election of an officer shall not of itself create contractual rights. Any vacancy occurring in any office of the Corporation by death, resignation, removal or otherwise, may be filled by the Board at any regular or special meeting.

Section 4.3. Powers and Duties. The officers of the Corporation shall have such powers and duties in the management of the Corporation as shall be stated in these bylaws or in a resolution of the Board which is not inconsistent with these bylaws and, to the extent not so stated, as generally pertain to their respective offices, subject to the control of the Board. The Secretary shall have the duty to record the proceedings of the meetings of the stockholders, the Board and any committees in a book to be kept for that purpose. The Board may require any officer, agent or employee to give security for the faithful performance of his or her duties.

Section 4.4. President. The President shall, subject to the control of the Board and, if there is one, the Chairman of the Board, have general supervision of the business of the Corporation and shall see that all orders and resolutions of the Board are carried into effect. The President shall execute all bonds, mortgages, contracts and other instruments of the Corporation requiring a seal, under the seal of the Corporation, except where required or permitted by law to be otherwise signed and executed and except that the other officers of the Corporation may sign and execute documents when so authorized by these bylaws, the Board or the President. In the absence

or disability of the Chairman of the Board, or if there is no Chairman of the Board, the President shall preside at all meetings of the stockholders and, provided the President is also a director, at the Board. The President shall also perform such other duties and may exercise such other powers as may from time to time be assigned to such officer by these bylaws or by the Board.

Section 4.5. Secretary. The Secretary shall attend all meetings of the Board and all meetings of the stockholders and record all of the proceedings thereat in a book or books to be kept for that purpose; the Secretary shall also perform like duties for committees of the Board when required. The Secretary shall give, or cause to be given, notice of all meetings of the stockholders and special meetings of the Board, and shall perform such other duties as may be prescribed by the Board, the Chairman of the Board or the President, to whom the Secretary shall report. If the Secretary shall be unable or shall refuse to cause to be given notice of all meetings of the stockholders and special meetings of the Board, and if there is no Assistant Secretary, than either the Board or the President may choose another officer to cause such notice to be given. The Secretary shall have custody of the seal of the Corporation and the Secretary or any Assistant Secretary, if there is one, shall have authority to affix the same to any instrument requiring it and when so affixed, it may be attested by the signature of the Secretary or by the signature of any such Assistant Secretary. The Board may give general authority to any other officer to affix the seal of the Corporation and to attest to the affixing by such officer’s signature. The Secretary shall see that all books, reports, statements, certificates and other documents and records required by law to be kept or filed are properly kept or filed, as the case may be.

ARTICLE V

Stock

Section 5.1. Stock Certificates and Uncertificated Shares. The shares of stock in the Corporation shall be represented by certificates, provided that the Board may provide by resolution or resolutions that some or all of any or all classes or series of the Corporation’s stock shall be uncertificated shares. Any such resolution shall not apply to shares represented by a certificate theretofore issued until such certificate is surrendered to the Corporation. Every holder of stock represented by certificates shall be entitled to have a certificate signed by or in the name of the Corporation by the Chairperson or Vice Chairperson of the Board, if any, or the President or a Vice President, and by the Treasurer or an Assistant Treasurer, or the Secretary or an Assistant Secretary, of the Corporation, representing the number of shares of stock registered in certificate form owned by such holder. If such certificate is manually signed by one officer or manually countersigned by a transfer agent or by a registrar, any other signature on the certificate may be a facsimile. 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 such person were such officer, transfer agent or registrar at the date of issue.

Except as otherwise expressly provided by law, the rights and obligations of the holders of uncertificated shares and the rights and obligations of the holders of certificates representing stock of the same class and series shall be identical.

Section 5.2. Lost, Stolen or Destroyed Stock Certificates; Issuance of New Certificates. The Corporation may issue a new certificate of stock or uncertificated shares in the place of any certificate theretofore issued by it, alleged to have been lost, stolen or destroyed, and the Corporation may require the owner of the lost, stolen or destroyed certificate, or such owner’s legal representative, to give the Corporation a bond sufficient to indemnify it against any claim that may be made against it on account of the alleged loss, theft or destruction of any such certificate or the issuance of such new certificate or uncertificated shares.

Section 5.3. Transfers. Stock of the Corporation shall be transferable in the manner prescribed by applicable law and in these bylaws. Transfers of stock shall be made on the books of the Corporation only by the person named in the certificate or by such person’s attorney lawfully constituted in writing and upon the surrender of the certificate therefore, properly endorsed for transfer and payment of all necessary transfer taxes; provided, however, that such surrender and endorsement or payment of taxes shall not be required in any case in which the officers of the Corporation shall determine to waive such requirement. Every certificate exchanged, returned, or surrendered to the Corporation shall be marked “Cancelled,” with the date of cancellation, by the Secretary or Assistant Secretary of the Corporation or the transfer agent thereof. No transfer of stock shall be valid as against the Corporation for any purpose until it shall have been entered in the stock records of the Corporation by an entry showing from and to whom transferred.

ARTICLE VI

Dividends

Section 6.1. Declaration. Dividends upon the capital stock of the Corporation, subject to any restrictions contained in the DGCL or the provisions of the certificate of incorporation, if any, may be declared by the Board at any regular or special meeting. Dividends may be paid in cash, in property or in shares of capital stock, subject to the provisions of the certificate of incorporation.

Section 6.2. Reserves. Before payment of any dividend, there may be set aside out of any funds of the Corporation available for dividends such sum or sums as the Board from time to time, in its absolute discretion, thinks proper as a reserve or reserves to meet contingencies, or for equalizing dividends, or for repairing or maintaining any property of the Corporation, or for such other purpose as the Board shall think conducive to the interest of the Corporation, and the Board may modify or abolish any such reserve in the manner in which it was created.

ARTICLE VII

Indemnification

Section 7.1. The Corporation shall indemnify and hold harmless, to the fullest extent permitted by applicable law as it presently exists or may hereafter be amended, any person

who was or is made or is threatened to be made a party or is otherwise involved in any claim, action, suit, or proceeding, whether civil, criminal, administrative or investigative (a “proceeding”) by reason of the fact that the person, or a person for whom he or she is the legal representative, is or was a director or officer of the Corporation or is or was serving at the request of the Corporation as a director, officer or fiduciary of another corporation or of a partnership, joint venture, trust, nonprofit entity, or other enterprise, including service with respect to employee benefit plans, against all expense, liability and loss (including attorneys’ fees, judgments, fines, ERISA excise taxes or penalties and amounts paid or to be paid in settlement) reasonably incurred or suffered by such person. The right to indemnification conferred in this bylaw shall be a contract right. Except as provided in Section 7.3 with respect to proceedings seeking to enforce rights to indemnification, the Corporation shall indemnify a person in connection with a proceeding initiated by such person or a claim made by such person against the Corporation only if such proceeding or claim was authorized in the specific case by the Board of the Corporation.

Section 7.2. Subject to applicable law, the Corporation shall pay the expenses incurred in defending any proceeding in advance of its final disposition, provided, however, that if and to the extent required by law the payment of expenses incurred by any person covered hereunder in advance of the final disposition of the proceeding shall be made only upon receipt of an undertaking by or on behalf of the affected person to repay all amounts advanced if it should ultimately be determined that such person is not entitled to be indemnified under this Article VII or otherwise.

Section 7.3. If a claim for indemnification (following the final disposition of such proceeding) or advancement of expenses under this Article VII is not paid in full within thirty (30) days, or such other period as might be provided pursuant to contract, after a written claim therefor has been received by the Corporation, the claimant may file suit to recover the unpaid amount of such claim or may seek whatever other remedy might be provided pursuant to contract. In any such action the Corporation shall have the burden of proving that the claimant was not entitled to the requested indemnification or advancement of expenses under applicable law. If successful in whole or in part, claimant shall be entitled to be paid the expense of prosecuting such claim to the fullest extent permitted by law. Neither the failure of the Corporation (including its directors, independent legal counsel or shareowners) to have made a determination prior to the commencement of such action that indemnification of the claimant is proper in the circumstances because the claimant has met the applicable standard of conduct set forth in the DGCL, nor an actual determination by the Corporation (including its directors, independent legal counsel or shareowners) that the claimant has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that the claimant has not met the applicable standard of conduct.

Section 7.4. Any determination regarding whether indemnification of any person is proper in the circumstances because such person has met the applicable standard of conduct set forth in the DGCL shall be made in accordance with the applicable provisions of Section 145 of the DGCL.

Section 7.5. The Corporation may, but shall not be required to, indemnify and hold harmless, to the fullest extent permitted by applicable law as it presently exists or may hereafter be amended, any person who was or is made or is threatened to be made a party or is otherwise involved in any claim, action, suit, or proceeding, whether civil, criminal, administrative or investigative (a “proceeding”) by reason of the fact that the person, or a person for whom he or she is the legal representative, is or was an employee or agent of the Corporation or is or was serving at the request of the Corporation as an employee or agent of another corporation or of a partnership, joint venture, trust, nonprofit entity, or other enterprise, including service with respect to employee benefit plans, against all expense, liability and loss (including attorneys’ fees, judgments, fines, ERISA excise taxes or penalties and amounts paid or to be paid in settlement) reasonably incurred or suffered by such person.

Section 7.6. The rights conferred on any person by this Article VII shall not be exclusive of any other rights which such person may have or hereafter acquire under any statute, provision of the certificate of incorporation, these bylaws, agreement, vote of shareowners or disinterested directors or otherwise.

Section 7.7. Any repeal or modification of the foregoing provisions of this Article VII shall not adversely affect any right or protection hereunder of any person with respect to any act or omission occurring prior to or at the time of such repeal or modification for which indemnification or advancement of expenses is sought.
