To be timely, such notice from a stockholder must be delivered to or mailed and received at the principal executive offices of the corporation pursuant to the timely notice requirements set forth in paragraph (b) of this Section 2; provided, however, that if the number of directors to be elected at an annual meeting is increased and there is no public announcement by the corporation naming the nominees for the additional directorships at least one hundred (100) days prior to the anniversary of the date of the previous year’s annual meeting of stockholders, a stockholder’s notice required by this paragraph (d) shall also be considered timely, but only with respect to nominees for the additional directorships, if it shall be delivered to the Secretary at the principal offices of the corporation not later than the close of business on the tenth (10th) day following the day on which public announcement is first made by the corporation.

disclosed in a proxy statement or other filings required to be made in connection with solicitations of proxies for the proposal pursuant to Regulation 14A under the 1934 Act. At the request of the Board of Directors, any person nominated by a stockholder for election as a director shall furnish to the Secretary of the corporation that information required to be set forth in the stockholder’s notice of nomination which pertains to the nominee. No person shall be eligible for election as a director of the corporation at an annual meeting unless nominated in accordance with the procedures set forth in this paragraph (d).

(e) Notwithstanding the foregoing provisions of this Section 2, a stockholder shall also comply with all applicable requirements of the 1934 Act and the rules and regulations thereunder with respect to the matters set forth in this Section 2; provided, however, that any references in these Bylaws to the 1934 Act or the rules and regulations thereunder are not intended to and shall not limit any requirements applicable to nominations or other proposals to be considered pursuant to this Section 2, and compliance with this Section 2 shall be the exclusive means for a stockholder to make nominations or submit other proposals at a meeting (other than, as provided in the last sentence of paragraph (c) of this Section 2, matters brought properly under and in compliance with Rule 14a-8 of the 1934 Act). Nothing in this Section 2 shall be deemed to affect any rights (i) of stockholders to request inclusion of proposals in the corporation’s proxy statement pursuant to Rule 14a-8 under the 1934 Act. or (ii) of the holders of any class or series of Preferred Stock to elect directors pursuant to any applicable provisions of the Certificate of Incorporation, as amended from time to time.

Section 3. Inspectors of Elections. Prior to any meeting of stockholders, the Board of Directors, the Chairman of the Board, a Vice Chairman of the Board, the Chief Executive Officer, the President or any other officer designated by the Board shall appoint one or more inspectors to act at such meeting and make a written report thereof and may designate one or more persons as alternate inspectors to replace any inspector who fails to act. If no inspector or alternate is able to act at the meeting of stockholders, the person presiding at the meeting shall appoint one or more inspectors to act at the meeting. Each inspector, before entering upon the discharge of his or her duties, shall take and sign an oath faithfully to execute the duties of inspector with strict impartiality and according to the best of his or her ability. The inspectors shall ascertain the number of shares outstanding and the voting power of each, determine the shares represented at the meeting and the validity of proxies and ballots, count all votes and ballots, determine and retain for a reasonable period a record of the disposition of any challenges made to any determination by the inspectors and certify their determination of the number of shares represented at the meeting and their count of all votes and ballots. The inspectors may appoint or retain other persons to assist them in the performance of their duties. The date and time of the opening and closing of the polls for each matter upon which the stockholders will vote at a meeting shall be announced at the meeting. No ballot, proxy or vote, nor any revocation thereof or change thereto, shall be accepted by the inspectors after the closing of the polls. In determining the validity and counting of proxies and ballots, the inspectors shall be limited to an examination of the proxies, any envelopes submitted therewith, any information provided by a stockholder who submits a proxy by telegram, cablegram or other electronic transmission from which it can be determined that the proxy was authorized by the stockholder, ballots and the regular books and records of the Corporation, and they may also consider other reliable information for the limited purpose of reconciling proxies and ballots submitted by or on behalf of banks, brokers, their nominees or similar persons which represent more votes than the holder

5

of a proxy is authorized by the record owner to cast or more votes than the stockholder holds of record. If the inspectors consider other reliable information for such purpose, they shall, at the time they make their certification, specify the precise information considered by them, including the person or persons from whom they obtained the information, when the information was obtained, the means by which the information was obtained and the basis for the inspectors’ belief that such information is accurate and reliable.

Section 4. Notice of Annual Meeting. Written notice of the annual meeting stating the place, date and hour of the meeting shall be given to each stockholder entitled to vote at such meeting not less than ten (10) nor more than sixty (60) days before the date of the meeting.

The officer who has charge of the stock ledger of the corporation shall prepare and make, or have prepared and made, at least ten (10) days before every meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting, arranged in alphabetical order, and showing the address of each stockholder and the number of shares registered in the name of each stockholder. Such list shall be open to the examination of any stockholder, 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 whole time thereof, and may be inspected by any stockholder who is present.

Section 6. Special Meetings. Special meetings of the stockholders, for any purpose or purposes, unless otherwise prescribed by statute or by the Certificate of Incorporation, as amended from time to time, may only be called as provided in this Section 6 by the Chairman of the Board or the President and shall be called by the President or Secretary at the request in writing of a majority of the Board of Directors. Such request shall state the purpose or purposes of the proposed meeting. The place, date and time of any special meeting shall be determined by the Board of Directors. Such determination shall include the record date for determining the stockholders having the right of and to vote at such meeting.

Section 7. Notice of Special Meeting. Written notice of a special meeting stating the place, date and hour of the meeting and the purpose or purposes for which the meeting is called shall be given not less than ten (10) nor more than sixty (60) days before the date of the meeting, to each stockholder entitled to vote at such meeting.

Section 8. Action at Special Meeting. Business transacted at any special meeting of stockholders shall be limited to the purposes stated in the notice.

Section 9. Conduct of Business. At every meeting of the stockholders, the Chairman of the Board, or, in his or her absence, the Chief Executive Officer, or, in his or her absence, such other person as may be appointed by the Board, shall act as chairman of the meeting. The Secretary of the corporation or a person designated by the chairman of the meeting shall act as secretary of the meeting. Unless otherwise approved by the chairman of the meeting, attendance at a stockholders’ meeting is restricted to stockholders of record, persons authorized in accordance with Section 12 of this Article II to act by proxy, and officers and directors of the corporation.

The chairman of the meeting shall call the meeting to order, establish the agenda, and conduct the business of the meeting in accordance therewith or, at the chairman’s discretion, it may be conducted otherwise in accordance with the wishes of the stockholders in attendance. The date and time of the opening and closing of the polls for each matter upon which the stockholders will vote at the meeting shall be announced at the meeting.

The chairman shall also conduct each meeting in an orderly manner, rule on the precedence of, and procedure on, motions and other procedural matters, and exercise discretion with respect to such procedural matters with fairness and good faith toward all those entitled to take part. Without limiting the foregoing, the chairman may (a) restrict attendance at any time to bona fide stockholders of record and their proxies and other persons in attendance at the invitation of the presiding officer or Board, (b) restrict use of audio or video recording devices at the meeting, and (c) impose reasonable limits on the amount of time taken up at the meeting on discussion in general or on remarks by any one stockholder. Should any person in attendance become unruly or obstruct the meeting proceedings, the chairman shall have the power to have such person removed from the meeting. The chairman may determine and declare at the meeting that any proposed item of business was not properly brought before the meeting or that a nomination of a person for election as a director of the corporation was not properly made in accordance with the provisions of this Section 9 and, in the case of an annual meeting, Section 2, or in the case of a special meeting, Section 8 above, and if the chairman should so determine, the chairman shall so declare at the meeting and any such business not properly brought before the meeting shall not be transacted and any such defective nomination of a person for election as a director of the corporation shall be disregarded.

Section 10. Quorum and Adjournments.

(a) The holders of a majority of the stock issued and outstanding and entitled to vote at any meeting of the stockholders, present in person or represented by proxy, shall constitute a quorum at all meetings of the stockholders for the transaction of business except as otherwise provided by statute or by the Certificate of Incorporation, as amended from time to time. A quorum, once established, shall not be broken by the withdrawal of enough votes to leave less than a quorum and the votes present may continue to transact business until adjournment. If, however, such quorum shall not be present or represented at any meeting of the stockholders, the stockholders entitled to vote thereat, present in person or represented by proxy, shall have the power to adjourn the meeting from time to time, without notice other than announcement at the meeting, until a quorum shall be present or represented. 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 meeting as originally notified. If the adjournment is for

7

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 stockholder of record entitled to vote at the meeting.

(b) When a quorum is present at any meeting, the vote of the holders of a majority of the stock having voting power present in person or represented by proxy shall decide any question brought before such meeting, except as required by applicable law or by the Certificate of Incorporation, as amended from time to time, or these Bylaws, a different vote is required, in which case such applicable law or express provision shall govern and control the decision of such question. Except as otherwise required by applicable law or by the Certificate of Incorporation, as amended from time to time, or these Bylaws, all elections of directors at which a quorum is present shall be determined by a majority of the votes cast, provided that if the number of nominees exceeds the number of directors to be elected, the directors shall be elected by the vote of a plurality of the votes cast. For purposes of this Section, a “majority of the votes cast” means that the number of shares voted “for” a director exceeds the number of the votes cast “against” a director. If a director is not elected, the director shall tender his or her resignation to the Board of Directors. The Nominating and Corporate Governance Committee will make a recommendation to the Board of Directors on whether to accept or reject such director’s resignation. The Board of Directors will act on the Nominating and Corporate Governance Committee’s recommendation and publicly disclose its decision and the rationale behind it within ninety (90) days from the date of the certification of the election results. The Nominating and Corporate Governance Committee in making its recommendation and the Board of Directors in making its decision may each consider any factors or other information that they consider appropriate and relevant. The director who tenders his or her resignation will not participate in the recommendation of the Nominating and Corporate Governance Committee or the Board of Directors’ decision with respect to his or her resignation, except to respond to requests for information. If a majority of the members of the Nominating and Corporate Governance Committee are subject to this evaluation process, then the independent directors on the Board of Directors (as most recently determined by the Board of Directors pursuant to the applicable guidelines) who are not subject to the evaluation will appoint a Board of Director committee comprised of independent directors who are not being evaluated solely for the purpose of conducting the required evaluation. The special committee will make the recommendation to the Board of Directors otherwise required of the Nominating and Corporate Governance Committee.

If a director’s resignation is accepted by the Board of Directors pursuant to this Bylaw, or if a nominee for director is not elected and the nominee is not an incumbent director, then the Board of Directors may fill the resulting vacancy pursuant to the provisions of Article III, Section 2, or may decrease the size of the board of Directors pursuant to the provisions of Article III, Section 1.

Section 11. Voting Rights and Proxies. Unless otherwise provided in the Certificate of Incorporation, as amended from time to time, each stockholder shall at every meeting of the stockholders be entitled to one (1) vote for each share of stock entitled to vote held of record by such stockholder. Each stockholder of record entitled to vote at a meeting of stockholders may vote in person or may authorize any other person or persons to vote or act for him by written proxy executed by the stockholder or his authorized agent or by a transmission permitted by law

8

and delivered to the Secretary of the corporation. No stockholder may authorize more than one proxy for his shares, and no proxy shall be voted on after three (3) years from its date, unless the proxy provides for a longer period. Any copy, facsimile transmission or other reliable reproduction of the writing or transmission created pursuant to this Section 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 such copy, facsimile transmission or other reproduction shall be a complete reproduction of the entire original writing or transmission.

Section 12. Action Without Meeting. No action shall be taken by the stockholders of the corporation except at an annual or special meeting of stockholders called in accordance with these Bylaws, and no action shall be taken by the stockholders by written consent.

A written waiver of notice, signed by the person entitled thereto, whether before or after the time of the meeting stated therein, shall be deemed equivalent to notice.

Section 8. Quorum. At all meetings of the Board a majority of the directors shall constitute a quorum for the transaction of business and the act of a majority of the directors present at any meeting at which there is a quorum shall be the act of the Board of Directors, except as may be otherwise specifically provided by statute or by the Certificate of Incorporation, as amended from time to time.

Section 9. Action Without Meeting. Unless otherwise restricted by the Certificate of Incorporation, as amended from time to time, or these Bylaws, any action required or permitted to be taken at any meeting of the Board of Directors or of any committee thereof may be taken without a meeting, if all members of the Board or committee thereof, as the case may be, consent thereto in writing or by electronic transmission, and the writing or writings or electronic transmissions are filed with the minutes of proceedings of the Board or committee.

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 of disqualification of a member of a committee, the member or members thereof present at any meeting and not disqualified from voting, whether or not he or they constitute a quorum, may unanimously appoint another member of the Board of Directors 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, 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 amending the Certificate of Incorporation, as amended from time to time, adopting an agreement of merger or consolidation, recommending to the stockholders the sale, lease or exchange of all or substantially all of the corporation’s property and assets, recommending to the stockholders a dissolution of the corporation or a revocation of a dissolution, or amending the Bylaws of the corporation; and, unless the resolution or the Certificate of Incorporation, as amended from time to time, expressly so provide, no such committee shall have the power or authority to declare a dividend or to authorize the issuance of stock.

CERTIFICATES OF STOCK

Section 1. Certificates of Stock. The shares of the corporation shall be represented by certificates, provided, however, that the Board may provide by resolution or resolutions that some or all of any or all classes or series of its stock shall be represented by uncertificated shares, and provided, further, that any such resolution shall not apply to shares represented by a certificate 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, (i) the Chairman or Vice Chairman of the Board of Directors, or the Chief Executive Officer, President or a Vice President, and (ii) the Chief Financial Officer or an Assistant Chief Financial Officer, or the Secretary or an Assistant Secretary of the corporation, certifying the number of shares owned by him, her or it in the corporation.

Certificates may be issued for partly paid shares and in such case upon the face or back of the certificates issued to represent any such partly paid shares, the total amount of the consideration to be paid therefor, and the amount paid thereon shall be specified.

If the corporation shall be authorized to issue more than one class of stock or more than one series of any class, the powers, designations, preferences and relative, participating, optional or other special rights of each class of stock or series thereof and the qualifications, limitations or restrictions of such preferences and/or rights shall be set forth in full or summarized on the face or back of the certificate which the corporation may issue to represent such class or series of stock, provided that, except as otherwise provided in Section 202 of the General Corporation Law of Delaware, in lieu of the foregoing requirements, there may be set forth on the face or back of the certificate which the corporation may issue to represent such class or series of stock, 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 and the qualifications, limitations or restrictions of such preferences and/or rights.

Section 2. Execution of Certificates. Any or all of the signatures on the certificate may be facsimile. In case any officer, transfer agent or registrar who has signed or whose

15

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.

Section 3. Lost Certificates. The Board may direct a new certificate or certificates to be issued in place of any certificate or certificates theretofore issued by the corporation alleged to have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming the certificate of stock to be lost, stolen or destroyed. When authorizing such issue of a new certificate or certificates, the Board may, in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed certificate or certificates, or the owner’s legal representative, to advertise the same in such manner as it shall require and/or to give the corporation a bond in such sum as it may direct as indemnity against any claim that may be made against the corporation with respect to the certificate alleged to have been lost, stolen or destroyed.

Section 4. Transfer of Stock. Upon surrender to the corporation or the transfer agent of the corporation of a certificate for shares duly endorsed or accompanied by proper evidence of succession, assignation or authority to transfer, it shall be the duty of the corporation to issue a new certificate to the person entitled thereto, cancel the old certificate and record the transaction upon its books.

Section 5. Fixing Record Date. In order that the corporation may determine the stockholders entitled to notice of or to vote at any meeting of stockholder or any adjournment thereof, or 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 shall not be more than sixty (60) nor less than ten (10) days before the date of such meeting, nor more than sixty (60) days prior to any other action. 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.

Section 6. Registered Stockholders. The corporation shall be entitled to recognize the exclusive right of a person registered on its books as the owner of shares to receive dividends, and to vote as such owner, and to hold liable for calls and assessments a person registered on its books as the owner of shares and shall not be bound to recognize any equitable or other claim to or interest in such share or shares on the part of any other person, whether or not it shall have express or other notice thereof, except as otherwise provided by the laws of Delaware.

ARTICLE VII

INDEMNIFICATION

Section 1. Indemnification of Directors and Executive Officers. The corporation shall indemnify its directors and executive officers to the fullest extent not prohibited by the Delaware General Corporation Law; provided, however, that the corporation may limit the extent

16

of such indemnification by individual contracts with its directors and executive officers; and, provided, further, that the corporation shall not be required to indemnify any director or executive officer in connection with any proceeding (or part thereof) initiated by such person or any proceeding by such person against the corporation or its directors, officers, employees or other agents unless (i) such indemnification is expressly required to be made by law, (ii) the proceeding was authorized by the Board of the corporation, and (iii) such indemnification is provided by the corporation, in its sole discretion, pursuant to the powers vested in the corporation under the Delaware General Corporation Law.

Section 2. Indemnification of Other Officers, Employees and Other Agents. The corporation shall have power to indemnify its other officers, employees and other agents as set forth in the Delaware General Corporation Law.

Section 3. Good Faith.

(a) For purposes of any determination under this Bylaw, a director or officer shall be deemed to have acted in good faith and in a manner reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, to have had no reasonable cause to believe that any conduct was unlawful, if such director’s or officer’s action is based on information, opinions, reports and statements, including financial statements and other financial data, in each case prepared or presented by:

(1) one or more officers or employees of the corporation whom the director or executive officer believed to be reliable and competent in the matters presented;

(2) counsel, independent accountants or other persons as to matters which the director or executive officer believed to be within such person’s professional competence; and

(3) with respect to a director, a committee of the Board upon which such director does not serve, as to matters within such Committee’s designated authority, which committee the director believes to merit confidence; so long as, in each case, the director or executive officer acts without knowledge that would cause such reliance to be unwarranted.

(b) The termination of any 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 was reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal proceeding, that the person had reasonable cause to believe that his or her consent was unlawful.

(c) The provisions of this Section 3 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 by the Delaware General Corporation Law.

Section 4. Expenses. The corporation shall advance, prior to the final disposition of any proceeding, promptly following request therefor, all expenses actually and reasonably incurred by any director or officer in connection with such proceeding upon receipt of an undertaking by or on behalf of such person to repay said amounts if it should be determined ultimately that such person is not entitled to be indemnified under this Bylaw or otherwise.

17

Notwithstanding the foregoing, unless otherwise determined pursuant to Section 4 of this Bylaw, no advance shall be made by the corporation if a determination is reasonably and promptly made (i) by the Board by a majority vote of a quorum consisting of directors who were not parties to the proceeding, or (ii) if such quorum is not obtainable, or, even if obtainable, a quorum of disinterested directors so directs, by independent legal counsel in a written opinion, that the facts known to the decision-making party at the time such determination is made demonstrate clearly and convincingly that such person acted in bad faith or in a manner that such person did not believe to be in or not opposed to the best interests of the corporation.

Section 5. Enforcement. Without the necessity of entering into an express contract, all rights to indemnification and advances to directors and officers under this Bylaw shall be deemed to be contractual rights and be effective to the same extent and as if provided for in a contract between the corporation and the director or officer. Any right to indemnification or advances granted by this Bylaw to a director or officer shall be enforceable by or on behalf of the person holding such right in any court of competent jurisdiction if (i) the claim for indemnification or advances is denied, in whole or in part, or (ii) no disposition of such claim is made within ninety (90) days of request therefor. The claimant in such enforcement action, if successful in whole or in part, shall be entitled to be paid also the expense of prosecuting his or her claim. The corporation shall be entitled to raise as a defense to any such action that the claimant has not met the standards of conduct that make it permissible under the Delaware General Corporation Law for the corporation to indemnify the claimant for the amount claimed. Neither the failure of the corporation (including its Board of Directors, independent legal counsel or its stockholders) to have made a determination prior to the commencement of such action that indemnification of the claimant is proper in the circumstances because he or she has met the applicable standard of conduct set forth in the Delaware General Corporation Law, nor an actual determination by the corporation (including its Board, independent legal counsel or its stockholders) 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 6. Non-Exclusivity of Rights. The rights conferred on any person by this Bylaw shall not be exclusive of any other right which such person may have or hereafter acquire under any statute, provision of the Certificate of Incorporation, as amended from time to time, Bylaws, 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 office. The corporation is specifically authorized to enter into individual contracts with any or all of its directors, officers, employees or agents respecting indemnification and advances, to the fullest extent not prohibited by the Delaware General Corporation Law.

Section 7. Survival of Rights. The rights conferred on any person by this Bylaw shall continue as to a person who has ceased to be a director, officer, employee or other agent and shall inure to the benefit of the heirs, executors and administrators of such a person.

18

Section 8. Insurance. To the fullest extent permitted by the Delaware General Corporation Law, the corporation, upon approval by the Board of Directors, may purchase insurance on behalf of any person required or permitted to be indemnified pursuant to this Bylaw.

Section 9. Amendments. Any repeal or modification of this Bylaw shall only be prospective and shall not affect the rights under this Bylaw in effect at the time of the alleged occurrence of any action or omission to act that is the cause of any proceeding against any agent of the corporation.

Section 10. Saving Clause. If this Bylaw or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the corporation shall nevertheless indemnify each director and officer to the full extent not prohibited by any applicable portion of this Bylaw that shall not have been invalidated, or by any other applicable law.

Section 11. Certain Definitions. For the purposes of this Bylaw, the following definitions shall apply:

(a) The term “proceeding” shall be broadly construed and shall include, without limitation, the investigation, preparation, prosecution, defense, settlement, arbitration and appeal of, and the giving of the testimony in, any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative.

(d) References to a “director,” “officer,” “employee,” or “agent” of the corporation shall include, without limitation, situations where such person is serving at the request of the corporation as a director, officer, employee, trustee or agent of another corporation, partnership, joint venture, trust or other enterprise.

(e) References to “other enterprises” shall include employee benefit plans; references to “fines” shall include any excise taxes assessed on a person with respect to an employee benefit plan; and references to “serving at the request of the corporation” shall include any service as a director, officer, employee or agent of the corporation which imposes duties on,

19

or involves services by, such director, officer, employee, or agent with respect to an employee benefit plan, its participants, or beneficiaries; and a person who acted in good faith and in a manner he reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner “not opposed to the best interests of the corporation” as referred to in this Bylaw.
