(b) Unless otherwise provided for in the Oklahoma General Corporation Act, as in effect at the time (the “Corporation Act”), or in the Corporation’s Certificate of Incorporation, as in effect at the time (the “Certificate of Incorporation”), the written notice of any meeting shall be given not less than ten (10) nor more than sixty (60) days before the date of the meeting to each shareholder entitled to vote at such meeting. If mailed, notice shall be deemed given when deposited in the United States mail, postage prepaid, directed to the shareholder at such shareholder’s address as it appears on the records of the Corporation. An affidavit of the secretary or an assistant secretary or of the stock transfer agent of the Corporation that the notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein.

(c) Notice of any meeting of shareholders shall not be required to be given to any shareholder who shall have waived such notice, and such notice shall be deemed waived by any shareholder who shall have submitted a written waiver of notice or who shall have attended such meeting in person or by proxy, except a shareholder who shall have attended such 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.

(d) Any meeting of the shareholders may be adjourned from time to time to reconvene at the same or some other place by any of the chairman of the Board, the individual designated as the presiding officer of the meeting or a majority of the shareholders present in person or represented by proxy at the meeting and entitled to vote, whether or not a quorum is present, and notice of any adjourned meeting of the shareholders need not be given if the time and place thereof are announced at the meeting at which the adjournment is taken; provided, however, that when the adjournment is for more than thirty (30) 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 shareholder of record entitled to vote at the meeting. At such adjourned meeting at which a quorum shall be present or represented, any business may be transacted which might have been transacted at the original meeting.

Section 2.05Quorum. Subject to the provisions of the Corporation Act or the Certificate of Incorporation, a majority of the shares of stock of the Corporation entitled to vote, the holders of which shall be present in person or represented by proxy, shall constitute a quorum for any meeting of the shareholders of the Corporation or any adjournment thereof. In the absence of a quorum at any meeting or any adjournment thereof, the holders of a majority of the shares entitled to vote thereat who are present in person or by proxy or, if none of the holders of any shares entitled to vote thereat are present, any officer entitled to preside at, or to act as secretary of, such meeting may adjourn such meeting from time to time. At any such adjourned meeting at which a quorum is present, any business may be transacted which might have been transacted at the meeting as originally called.

Section 2.06Voting.

(a) Each shareholder shall, at each meeting of the shareholders, be entitled to vote in person, or by proxy, each share of the stock of the Corporation having voting rights on the matter

in question and which shall have been held by such shareholder and registered in such shareholder’s name on the books of the Corporation:

(i) on the date fixed pursuant to Section 2.07 of these by-laws (the “By-laws”) as the record date for the determination of shareholders entitled to notice of and to vote at such meeting; or

(ii) if no such record date shall have been so fixed, then at the close of business on the day next preceding the day on which notice of the meeting shall be given or if notice of the meeting shall be waived, at the close of business on the day next preceding the day on which meeting shall be held.

(b) Shares of its own stock belonging to the Corporation or to another corporation, limited liability company, partnership or other business entity, if a majority of the shares, membership interests, partnership interests or other applicable equity interests entitled to vote in the election of directors, managers or other similar positions in such other entity is held, directly or indirectly, by the Corporation, shall neither be entitled to vote nor be counted for quorum purposes. Persons holding stock of the Corporation in a fiduciary capacity shall be entitled to vote such stock. Persons whose stock is pledged shall be entitled to vote, unless the transfer by the pledgor on the books of the Corporation shall have expressly empowered the pledgee to vote thereon, in which case only the pledgee, or the pledgee’s proxy, may represent such stock and vote thereon. Shares having voting power standing of record in the names of two or more persons, whether fiduciaries, members of a partnership, joint tenants, tenants in common, tenants by the entirety or otherwise, or with respect to which two or more persons have the same fiduciary relationship, shall be voted in accordance with the provisions of the Corporation Act.

(c) A shareholder entitled to vote at a meeting of shareholders or to express consent or dissent to corporate action in writing without a meeting may authorize another person or persons to act for the shareholder by proxy, but no proxy shall be voted or acted upon after three (3) years from its date, unless the proxy provides for a longer period. The following shall constitute a valid means by which a shareholder may grant such authority:

(i) by executing a writing authorizing another person or persons to act for him or her as proxy. Execution may be accomplished by the shareholder or the shareholder’s authorized officer, director, employee, agent or other authorized person signing the writing or causing his or her signature to be affixed to the writing by any reasonable means including, but not limited to, by facsimile signature; or

(ii) by authorizing another person or persons to act for him or her as proxy by transmitting or authorizing transmission of a facsimile, electronic mail, telegram, cablegram, or other means of electronic transmission capable of being reduced to writing to the person who will be the holder of the proxy or to a proxy solicitation firm, proxy support service organization, or like agent duly authorized by the person who will be the holder of the proxy to receive the transmission; provided, that any facsimile, electronic mail, telegram, cablegram, or other acceptable means of electronic

transmission must either set forth, or be submitted with information from which it can be determined, that such transmission was authorized by the shareholder. If it is determined that a facsimile, electronic mail, telegram, cablegram, or other electronic transmission is valid, the inspectors or, if there are no inspectors, any other person making that determination shall specify the information upon which they relied.

Any copy, facsimile, or other reliable reproduction of the writing or transmission created pursuant to this subsection may be substituted or used in lieu of the original writing or transmission for any and all purposes for which the original writing or transmission could be used; provided, that the copy, facsimile, or other reproduction shall be a complete reproduction of the entire original writing or transmission.

(d) The attendance at any meeting by a shareholder who may theretofore have given a proxy shall not have the effect of revoking the same unless the shareholder (i) shall in writing so notify the secretary of the meeting prior to the voting of a proxy or (ii) votes at the meeting.

(e) At any meeting of the shareholders, all matters, except as otherwise provided in the Certificate of Incorporation, in the By-laws or by law or applicable stock exchange rule, and except for the election of directors, shall be decided by the vote of the holders of shares representing a majority of the voting power of the shareholders present in person or by proxy and entitled to vote thereat and thereon, provided that a quorum is present. With respect to the election of directors at any meeting of the shareholders, each nominee shall be elected by the affirmative vote of a majority of the votes cast with respect to that director’s election by the shareholders present in person or by proxy at the meeting and entitled to vote for the election of directors, provided that a quorum is present and, provided further, that directors shall be elected by a plurality of the votes cast at any meeting of shareholders for which (i) the secretary of the Corporation receives a notice that a shareholder has nominated a person for election to the Board in compliance with the advance notice requirements for shareholder nominees for director set forth in Section 3.03(c) and (d) of these By-laws and (ii) such nomination has not been withdrawn by such shareholder on or before the tenth (10^th) day before the Corporation first mails its notice of meeting for such meeting to the shareholders. The vote at any meeting of the shareholders on any matter need not be by written ballot, except election of directors, unless so directed by the presiding officer of the meeting. On a vote by ballot, each ballot shall be signed by the shareholder voting, or by the shareholder’s proxy, if there be such a proxy, and it shall state the number of shares voted.

Section 2.07Fixing Date for Determination of Shareholders of Record. In order that the Corporation may determine the shareholders entitled to notice of, or to vote at any meeting of shareholders or any adjournment thereof, the Board may fix, in advance, 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 not be more than sixty (60) nor less than ten (10) days before the date of such meeting. If no record date is fixed by the directors, the record date for determining shareholders entitled to notice of or to vote at a meeting of shareholders 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 shareholders entitled to notice of, or to vote at, a meeting of shareholders shall apply to any adjournment of such meeting; provided, however, that the Board may fix a new record date for the adjourned meeting. In order that the Corporation may

determine shareholders entitled to receive payment of any dividend or other distribution, or allotment of any rights, or 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, in advance, 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 not be more than sixty (60) days prior to such action, unless otherwise provided by the Certificate of Incorporation. If, in any case involving the determination of shareholders for any purpose other than notice of or voting at a meeting of shareholders, the Board shall not fix a record date, the record date for determining shareholders for such purpose shall be the close of business on the day on which the Board shall adopt the resolution relating thereto.

Section 2.08List of Shareholders. The secretary of the Corporation shall cause to be prepared and made, at least ten (10) days before every meeting of shareholders, a complete list of the shareholders entitled to vote at the meeting, arranged in alphabetical order, and showing the address of each shareholder and the number of shares registered in the name of each shareholder. Such list shall be open to the examination of any shareholder, for any purpose germane to the meeting, during ordinary business hours, for a period of at least ten (10) days prior to the meeting, either at a place within the city where the meeting is to be held, which place shall be specified in the notice of the meeting, or, if not so specified, at the place where the meeting is to be held. The list shall also be produced and kept at the time and place of the meeting during the entire duration thereof, and may be inspected by any shareholder who is present for any purpose germane to the meeting.

Section 2.09Chairman and Secretary of the Meeting. Meetings of the shareholders shall be presided over by the chairman of the Board or, in his absence, by the next senior officer of the Corporation present. If no senior officers are present, the meeting of shareholders shall be presided over by a presiding officer to be chosen by the shareholders. The secretary of the Corporation, or in such officer’s absence, an assistant secretary, shall act as secretary of the meeting, but if none are present, the presiding officer of the meeting shall appoint a secretary of the meeting.

Section 2.10Inspectors. If at any meeting of the shareholders a vote by written ballot shall be taken on any question, the presiding officer of the meeting may appoint an inspector or inspectors to act with respect to such vote. Each inspector so appointed shall first subscribe an oath to execute faithfully the duties of an inspector at such meeting with strict impartiality and according to the best of such inspector’s ability. Such inspector(s) shall decide upon the qualification of the voters, shall report the number of shares represented at the meeting and entitled to vote on such question, shall conduct and accept the votes, and, when the voting is completed, shall ascertain and report the number of shares voted respectively for and against the question. Reports of the inspector(s) shall be in writing and subscribed and delivered by them to the secretary of the Corporation. The inspector(s) need not be shareholders of the Corporation, and any officer of the Corporation may be an inspector on any question other than a vote for or against a proposal in which such officer shall have a material interest.

Section 2.11Conduct of Meetings.

(a) At an annual meeting of the shareholders, a matter (other than nominations of directors which shall be governed by Sections 3.03(c) and (d) of these By-laws) may only be

considered if it is brought before the meeting: (i) pursuant to the Corporation’s notice of meeting; (ii) by or at the discretion of the Board; or (iii) by any shareholder of the Corporation who is a shareholder of record at the time of giving the notice provided for herein, who shall be entitled to vote at such meeting and who complies with the notice procedures set forth in Section 2.11(b). Nothing in this Section 2.11(a) or 2.11(b) will be deemed to affect the rights of shareholders to request inclusion of proposals in the Company’s proxy statement pursuant to Rule 14a-8 of the Securities Exchange Act of 1934, as amended.

(b) For business to be properly brought before an annual meeting by a shareholder pursuant to Section 2.11(a) above, the shareholder must have given timely notice thereof in writing to the secretary of the Corporation. To be timely, a shareholder’s notice must be received at the Principal Office of the Corporation not less than one hundred twenty (120) calendar days before the first anniversary of the date that the Corporation’s proxy statement was released to shareholders in connection with the previous year’s annual meeting; provided, however, that if the date of the meeting is changed by more than thirty (30) days from the first anniversary date of the previous year’s meeting, notice by a shareholder must be received no later than the close of business on the tenth (10^th) day following the earlier of the day on which notice of the date of the meeting was mailed to shareholders or public disclosure of such date was made. In no event will the postponement or adjournment of an annual meeting, or the public disclosure of the postponement or adjournment of an annual meeting, commence a new time period for the giving of a shareholder’s notice as described above. Such shareholder notice shall set forth as to each matter the shareholder proposes to bring before the meeting: (1) a brief description of and the reasons for proposing such matter at the meeting; (2) with respect to the shareholder giving notice and the beneficial owner, if any, on whose behalf the proposal is being made: (A) the name and address of such person; (B) the class or series and number of shares of the Corporation which are owned beneficially and of record by such person and any affiliates or associates of such person; (C) the name of each nominee holder of shares of all stock of the Corporation owned beneficially but not of record by such person or any affiliates or associates of such person, and the number of such shares of stock of the Corporation held by each such nominee holder, (D) whether and the extent to which any derivative instrument, swap, option, warrant, short interest, hedge or profit interest or other transaction has been entered into by or on behalf of such person, or any affiliates or associates of such person, with respect to stock of the Corporation and (E) whether and the extent to which any other transaction, agreement, arrangement or understanding (including any short position or any borrowing or lending of shares of stock of the Corporation) has been made by or on behalf of such person, or any affiliates or associates of such person, the effect or intent of any of the foregoing being to mitigate loss to, or to manage risk or benefit of stock price changes for, such person, or any affiliates or associates of such person, or to increase or decrease the voting power or pecuniary or economic interest of such person, or any affiliates or associates of such person, with respect to stock of the Corporation; (3) a representation that the shareholder giving notice intends to appear in person or by proxy at the annual meeting to bring such business before the meeting; (4) any material interest of such shareholder of record, the beneficial owner, if any, on whose behalf the proposal is made or any affiliate or associate of any of the foregoing, in such proposal; (5) a description of all agreements, arrangements and understandings between such shareholder, the beneficial owner, if any, on whose behalf the proposal is made or any affiliate or associate of any of the foregoing, and any other person or persons (including their names) in connection with the proposal of such business by such shareholder; and (6) all other information that would be required to be disclosed by such shareholder or the beneficial owner, if any, on whose behalf the proposal

is made as a participant in a solicitation of proxies for the election of directors in a contested election, or would be otherwise required to be disclosed in connection with such solicitation, in each case pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended. The foregoing information shall be supplemented by such shareholder and beneficial owner, if any, not later than ten (10) days after the record date for the meeting to disclose all such information as of the record date.

(c) Notwithstanding anything in these By-laws to the contrary, no business shall be proper at a meeting unless brought before it in accordance with the procedures set forth herein. Further, a shareholder shall also comply with all applicable requirements of the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder with respect to the matters set forth herein.

(d) The chairman of the Board or the individual designated as presiding officer of the meeting shall, if the facts warrant, determine and declare to the meeting that business was not properly brought before the meeting and in accordance with the procedures proscribed herein, and, if the chairman of the Board or the presiding officer of the meeting should so determine, then any such business shall not be transacted.

(e) Notwithstanding anything provided herein to the contrary, the procedures for submission of shareholder proposals have not expanded, altered or affected in any manner whatever, the rights or limitations that may exist regarding the ability of a shareholder of the Corporation to submit a proposal for consideration by shareholders of the Corporation under Oklahoma or federal law.

(a) No director shall vote on a question in which such director is interested, except the election of the chairman of the Board, a chief executive officer, a president, or other officer of the Corporation or members of any committee of the Board, but, in the absence of fraud, no contract or other transaction of the Corporation shall be affected or invalidated in any way by the fact that any of the directors of the Corporation are in any way interested in or connected with any other party to such contract or transaction, or are themselves parties to such contract or transaction, provided, that such interest or connection shall be fully disclosed or otherwise be known to the Board at the meeting of the Board at which such contract or transaction is authorized or confirmed, provided further, that the contract or transaction is fair as to the Corporation at the time authorized or confirmed by the Board, and, provided further, that at the meeting of the Board at which such contract or transaction is to be authorized or confirmed, a quorum be present which may include common or interested directors for purposes of determining the presence of a quorum, and the Board in good faith authorizes or confirms such contract or transaction by the affirmative votes of a majority of the disinterested directors, even though the disinterested directors may be less than a quorum. The mere ownership of stock in another corporation by a director shall not disqualify such director to vote in respect of any transaction between the Corporation and such other corporation, provided, the other provisions of this Section 3.17 are complied with.

(b) No contract or other transaction between the Corporation and any other entity shall be affected by the fact that any of the directors of the Corporation are interested in or are directors, officers, managers or similarly situated representatives of such other entity, if such contract or transaction be made, authorized, or confirmed by the Board in the manner provided in the preceding paragraph, or by any committee of the Board having the requisite authority, by vote of a majority of the members of such committee not so interested; and any director individually may be a party to or may be interested in any contract or transaction of the Corporation, provided, that such contract or transaction shall be approved or ratified by the Board or by any committee of the Board having the requisite authority, in the manner herein set forth.

(c) The Board, in its discretion, may submit any contract or act of the Corporation or of the Board for approval or ratification at any annual meeting of the shareholders, or at any special meeting of shareholders, the notice of which shall state that it is called for the purpose, or in part for the purpose, of considering any such act or contract, and any such contract or act that shall be

approved or be ratified by the vote of the holders of a majority in voting interest of the shares of stock of the Corporation entitled to vote thereat, shall be as valid and as binding upon the Corporation and upon all the shareholders as though it had been approved and ratified by every shareholder of the Corporation.

(d) Any director of the Corporation may vote upon any contract or other transaction between the Corporation and any subsidiary entity notwithstanding the fact that such person is also a director, officer, manager or similarly situated representative of such subsidiary entity.

(e) No contract or agreement between the Corporation and (i) any other corporation or party which owns a majority of the capital stock of the Corporation or (ii) any subsidiary of any such other corporation or party, shall be made or entered into without the affirmative vote of a majority of the whole Board at a regular meeting of the Board.

(f) Notwithstanding anything to the contrary in the foregoing paragraphs of this Section 3.17, in the case of contracts, transactions, and acts of the Corporation, of the Board, or of committees thereof that require shareholder and/or director approval under any provision of the Certificate of Incorporation or of law by a higher proportion of the voting power of the outstanding voting stock than a majority of a quorum of the shareholders or approval by the Independent Directors (as defined and required by the Certificate of Incorporation), ratification by the shareholders and/or approval by the Independent Directors of such contracts, transactions, and acts shall require the affirmative vote of such higher proportion of such voting power and/or approval by the Independent Directors, and any contract, transaction, act, or agreement referred to in the foregoing paragraphs shall be subject to any such applicable provisions of the Certificate of Incorporation or of law.

SHARES AND THEIR TRANSFER

Every certificate surrendered to the Corporation for exchange or transfer shall be canceled, and no new certificate or certificates shall be issued in exchange for any existing certificate until such existing certificate shall have been so canceled, except in cases provided for in Section 7.04 of these By-laws. Notwithstanding the above, the Board may provide by resolution or resolutions that some or all of any and all classes or series of stock of the Corporation may be uncertificated shares, provided, the shares represented by a certificate shall not become uncertificated shares until such time as the certificate for such shares is surrendered to the Corporation and shall have been canceled and, provided further, that any holder of uncertificated shares who makes written request to the Corporation shall be entitled to receive a certificate representing such holder’s shares of the stock in the Corporation.

Section 7.02Transfers of Stock.

shall be made for collateral security, and not absolutely, such fact shall be stated expressly in the entry of transfer if, when the certificate or certificates shall be presented for transfer, both the transferor and the transferee request the Corporation to do so.

Section 7.03Regulations. The Board may make such rules and regulations as it may deem expedient, not inconsistent with these By-laws, concerning the issue, transfer, and registration of certificates for shares and uncertificated shares of the stock of the Corporation.

INDEMNIFICATION

Section 8.01Actions, Suits, or Proceedings Other Than by or in the Right of the Corporation. The Corporation shall 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 the person 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, partnership, limited liability company, joint venture, trust, or other enterprise or as a member of any committee or similar body, against expenses (including attorneys’ fees and expenses), judgments, fines, and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding if the person acted in good faith and in a manner the person 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 the person’s conduct was unlawful. The termination of any action, suit, investigation 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 the person reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action or proceeding, that the person had reasonable cause to believe that the person’s conduct was unlawful.

Section 8.02Actions, Suits, or Proceedings by or in the Right of the Corporation. The Corporation shall 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 that the person 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, partnership, limited liability company, joint venture, trust, or other enterprise against expenses (including attorneys’ fees and expenses) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted in good faith in a manner the person reasonably believed to be in or not opposed to the best interests of the Corporation 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 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 shall deem proper.

Section 8.03Indemnity if Successful. Notwithstanding the other provisions of this Article VIII, to the extent that a present or former director, officer, employee, or agent of the Corporation has been successful on the merits or otherwise in defense of any action, suit, or proceeding referred to in Sections 8.01 and 8.02, or in defense of any claim, issue, or matter therein, the person shall be indemnified against expenses (including attorneys’ fees and expenses) actually and reasonably incurred by such person in connection therewith.

Section 8.04Determination of Right of Indemnification. Any indemnification under Sections 8.01 or 8.02 (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 present or former director, officer, employee, or agent is proper in the circumstances because such person has met the applicable standard of conduct set forth in Sections 8.01 and 8.02. Such determination shall be made (i) by the Board by a majority vote of the directors who were not parties to such action, suit, or proceeding, even though less than a quorum; (ii) by a committee of directors designated by a majority vote of directors, even though less than a quorum; (iii) if there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion; or (iv) by the shareholders.

Section 8.05Advance of Expenses. Expenses (including attorneys’ fees and expenses) incurred by an officer or director in defending a civil or criminal 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 such director or officer to repay such amount if it shall ultimately be determined that such person is not entitled to be indemnified by the Corporation as authorized in this Article VIII. Such expenses (including attorneys’ fees and expenses) incurred by former directors or officers or other employees and agents may be so paid under such terms and conditions, if any, as the Board may deem appropriate.

Section 8.06Provisions of By-laws not Exclusive. The indemnification and advancement of expenses provided by, or granted pursuant to, this Article VIII shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under the Certificate of Incorporation, any by-law, agreement, vote of shareholders or disinterested directors or otherwise, both as to such person’s official capacity and as to action in another capacity while holding such office, it being the policy of the Corporation that indemnification of the persons specified in Sections 8.01 and 8.02 shall be made to the fullest extent permitted by law. The provisions of this Article VIII shall not be deemed to preclude the indemnification of any person who is not specified in Section 8.01 or Section 8.02 but whom the Corporation has the power or obligation to indemnify under the provisions of the Corporation Act, or otherwise.

Section 8.07Insurance. Upon resolution passed by the Board, the Corporation may 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, partnership, limited liability company, joint venture, trust, or other enterprise or as a member of any committee or similar body, against any liability asserted against the person and incurred by the person in any such capacity, or arising out of the person’s status as such, whether or not the Corporation would have the power to indemnify the person against such liability under the provisions of this Article VIII.

Section 8.08Constituent Corporations. For the purposes of this Article VIII, references to “the Corporation” include, in addition to the resulting corporation or other entity, any constituent corporation or entity (including any constituent of a constituent) absorbed in a consolidation or merger which, if its separate existence had continued, would have had power and authority to indemnify its directors, officers, and employees, or agents, so that any person who is or was a director, officer, employee, or agent of such constituent corporation or entity or is or was serving at the request of such constituent corporation or entity as a director, officer, employee, or agent of another corporation, partnership, joint venture, trust, limited liability company or other enterprise or as a member of any committee or similar body shall stand in the same position under the provisions of this Article VIII with respect to the resulting or surviving corporation as such person would have with respect to such constituent corporation if its existence had continued.

(b) For purposes of any determination under Section 8.04, a person shall be deemed to have acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Corporation, or, with respect to any criminal action or proceeding, to have had no reasonable cause to believe such person’s conduct was unlawful, if such person’s action is based on the records or books of account of the Corporation or another enterprise, or on information supplied to such person by the officers of the Corporation or another enterprise in the course of their duties, or on the advice of legal counsel for the Corporation or another enterprise or on information or records given or reports made to the Corporation or another enterprise by an independent certified public accountant or by an appraiser or other expert selected with reasonable care by the Corporation or another

enterprise. The provisions of this Section 8.09(b) shall not be deemed to be exclusive or to limit in any way the circumstances in which a person may be deemed to have met the applicable standard of conduct set forth in Section 8.01 or Section 8.02, as the case may be.
