ARTICLE II

STOCKHOLDERS

1. CERTIFICATES REPRESENTING STOCK. Certificates representing stock in the corporation shall be signed by, or in the name of, the corporation by the Chairperson or Vice-Chairperson of the Board of Directors, if any, or by the President or a Vice-President and by the Treasurer, an Assistant Treasurer, the Secretary or an Assistant Secretary of the corporation. Any or all the signatures on any such 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.

Whenever the corporation shall be authorized to issue more than one class of stock or more than one series of any class of stock, and whenever the corporation shall issue any shares of its stock as partly paid stock, the certificates representing shares of any such class or series or of any such partly paid stock shall set forth thereon the statements prescribed by the General Corporation

Law of the State of Delaware (the “Delaware General Corporation Law”). Any restrictions on the transfer or registration of transfer of any shares of stock of any class or series shall be noted conspicuously on the certificate representing such shares.

The corporation may issue a new certificate of stock or uncertificated shares in place of any certificate theretofore issued by it, alleged to have been lost, stolen, or destroyed, and the Board of Directors 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 the corporation 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 any such new certificate or uncertificated shares.

2. UNCERTIFICATED SHARES. Subject to any conditions imposed by the Delaware General Corporation Law, the Board of Directors of the corporation may provide by resolution or resolutions that some or all of any or all classes or series of the stock of the corporation shall be uncertificated shares. Within a reasonable time after the issuance or transfer of any uncertificated shares, the corporation shall send to the registered owner thereof any written notice prescribed by the Delaware General Corporation Law.

3. FRACTIONAL SHARE INTERESTS. The corporation may, but shall not be required to, issue fractions of a share. If the corporation does not issue fractions of a share, it shall (1) arrange for the disposition of fractional interests by those entitled thereto, (2) pay in cash the fair value of fractions of a share as of the time when those entitled to receive such fractions are determined, or (3) issue scrip or warrants in registered form (either represented by a certificate or uncertificated) or bearer form (represented by a certificate) which shall entitle the holder to receive a full share upon the surrender of such scrip or warrants aggregating a full share. A certificate for a fractional share or an uncertificated fractional share shall, but scrip or warrants shall not unless otherwise provided therein, entitle the holder to exercise voting rights, to receive dividends thereon, and to participate in any of the assets of the corporation in the event of liquidation. The Board of Directors may cause scrip or warrants to be issued subject to the conditions that they shall become void if not exchanged for certificates representing the full shares or uncertificated full shares before a specified date, or subject to the conditions that the shares for which scrip or warrants are exchangeable may be sold by the corporation and the proceeds thereof distributed to the holders of scrip or warrants, or subject to any other conditions which the Board of Directors may impose.

4. STOCK TRANSFERS. Upon compliance with provisions restricting the transfer or registration of transfer of shares of stock, if any, transfers or registration of transfers of shares of stock of the corporation shall be made only on the stock ledger of the corporation by the registered holder thereof, or by the registered holder’s attorney thereunto authorized by power of attorney duly executed and filed with the Secretary of the corporation or with a transfer agent or a registrar, if any, and, in the case of shares represented by certificates, on surrender of the certificate or certificates for such shares of stock properly endorsed and the payment of all taxes due thereon.

5. RECORD DATE FOR STOCKHOLDERS. In order that the corporation may

determine the stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof, the Board of Directors 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 of Directors, and which record date shall not be more than sixty nor less than ten days before the date of such meeting. If no record date is fixed by the Board of Directors, the record date for determining stockholders entitled to notice of or 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; provided, however, that the Board of Directors may fix a new record date for 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 of Directors 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 of Directors, and which date shall not be more than sixty days after the date upon which the resolution fixing the record date is adopted by the Board of Directors. If no record date has been fixed by the Board of Directors, the record date for determining the stockholders entitled to consent to corporate action in writing without a meeting, when no prior action by the Board of Directors is required by the Delaware General Corporation 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 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. If no record date has been fixed by the Board of Directors and prior action by the Board of Directors is required by the Delaware General Corporation 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 of Directors 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 of Directors 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 has been fixed by the Board of Directors, the record date for determining stockholders for any such purpose shall be at the close of business on the day on which the Board of Directors adopts the resolution relating thereto.

6. MEANING OF CERTAIN TERMS. As used herein in respect of the right to notice of a meeting of stockholders or a waiver thereof or to participate or vote thereat or to consent or dissent in writing in lieu of a meeting, as the case may be, the term “share” or “shares” or “share of stock” or “shares of stock” or “stockholder” or “stockholders” refers to an outstanding share or shares of stock and to a holder or holders of record of outstanding shares of stock when the corporation is authorized to issue only one class of shares of stock, and said reference is also

intended to include any outstanding share or shares of stock and any holder or holders of record of outstanding shares of stock of any class upon which or upon whom the certificate of incorporation confers such rights where there are two or more classes or series of shares of stock or upon which or upon whom the Delaware General Corporation Law confers such rights notwithstanding that the certificate of incorporation may provide for more than one class or series of shares of stock, one or more of which are limited or denied such rights thereunder; provided, however, that no such right shall vest in the event of an increase or a decrease in the authorized number of shares of stock of any class or series which is otherwise denied voting rights under the provisions of the certificate of incorporation, except as any provision of law may otherwise require.

7. STOCKHOLDER MEETINGS.

(a) TIME. The annual meeting for the election of directors, and for such other business as may be stated in the notice of the meeting, shall be held on the date and at the time fixed, from time to time, by the Board of Directors, provided, that the first annual meeting shall be held on a date within thirteen months after the organization of the corporation, and each successive annual meeting shall be held on a date within thirteen months after the date of the preceding annual meeting. A special meeting shall be held on the date and at the time fixed by the Board of Directors.

(b) PLACE. Annual meetings and special meetings may be held at such place, either within or without the State of Delaware, as the Board of Directors may, from time to time, fix. Whenever the Board of Directors shall fail to fix such place, the meeting shall be held at the registered office of the corporation in the State of Delaware. The Board of Directors may also, in its sole discretion, determine that the meeting shall not be held at any place, but may instead be held solely by means of remote communication as authorized by Section 211(a)(2) of the Delaware General Corporation Law. If a meeting by remote communication is authorized by the Board of Directors in its sole discretion, and subject to guidelines and procedures as the Board of Directors may adopt, stockholders and proxyholders not physically present at a meeting of stockholders may, by means of remote communication participate in a meeting of stockholders and be deemed present in person and vote at a meeting of stockholders whether such meeting is to be held at a designated place or solely by means of remote communication, provided that (a) the corporation shall implement reasonable measures to verify that each person deemed present and permitted to vote at the meeting by means of remote communication is a stockholder or proxyholder, (b) the corporation shall implement reasonable measures to provide such stockholders and proxyholders a reasonable opportunity to participate in the meeting and to vote on matters submitted to the stockholders, including an opportunity to read or hear the proceedings of the meeting substantially concurrently with such proceedings, and (c) if any stockholder or proxyholder votes or takes other action at the meeting by means of remote communication, a record of such vote or other action shall be maintained by the corporation.

(c) CALL. Annual meetings and special meetings may be called by the Board of Directors or by any officer instructed by the Board of Directors to call the meeting.

(d) NOTICE OR WAIVER OF NOTICE. Written notice of all meetings shall be given, which shall state the place, if any, date, and hour of the meeting, the means of remote communication, if any, by which stockholders and proxyholders may be deemed to be present in person and vote at such meeting, and in the case of a special meeting, the purpose or purposes for which the meeting is called. The notice of an annual meeting shall state that the meeting is called for the election of directors and for the transaction of other business which may properly come before the meeting, and shall (if any other action which could be taken at a special meeting is to be taken at such annual meeting) state the purpose or purposes. The notice of any meeting shall also include, or be accompanied by, any additional statements, information, or documents prescribed by the Delaware General Corporation Law. Except as otherwise provided by the Delaware General Corporation Law, the written notice of any meeting shall be given not less than ten days nor more than sixty days before the date of the meeting to each stockholder entitled to vote at such meeting. If mailed, notice is 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 the corporation. If a meeting is adjourned to another time or place, notice need not be given of the adjourned meeting if the time, place, if any, thereof, and the means of remote communications, if any, by which stockholders and proxyholders may be deemed to be present in person and vote at such adjourned meeting 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 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. Whenever notice is required to be given under the Delaware General Corporation Law, certificate of incorporation or bylaws, a written waiver signed by the person entitled to notice, or a waiver by electronic transmission by the person entitled to notice, whether before or after the time stated therein, shall be deemed equivalent to notice. Attendance of a stockholder at a meeting of stockholders shall constitute a waiver of notice of such meeting, except when the stockholder attends the meeting for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened. Neither the business to be transacted at, nor the purpose of, any regular or special meeting of the stockholders need be specified in any written waiver of notice or any waiver by electronic transmission unless so required by the certificate of incorporation or these bylaws. No business other than that stated in the notice shall be transacted at any meeting without the unanimous consent of all the stockholders entitled to vote thereat.

(e) STOCKHOLDER LIST. The officer 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, 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 for a period of at least ten days prior to the meeting 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 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 the list shall 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. If the meeting is to be held solely by means of remote communication, then the 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. The stock ledger shall be the only evidence as to who are the stockholders entitled to examine the stock ledger, the list required by this section or the books of the corporation, or to vote in person or by proxy at any meeting of stockholders.

(f) CONDUCT OF MEETING. Meetings of the stockholders shall be presided over by one of the following officers in the order of seniority and if present and acting - the Chairperson of the Board of Directors, if any, the Vice-Chairperson of the Board of Directors, if any, the President, a Vice-President, or, if none of the foregoing is in office and present and acting, by a chairperson to be chosen by the stockholders. The Secretary of the corporation, or in such Secretary’s absence, an Assistant Secretary, shall act as secretary of every meeting, but if neither the Secretary nor an Assistant Secretary is present the chairperson of the meeting shall appoint a secretary of the meeting.

(g) PROXY REPRESENTATION. 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 3 years from its date, unless the proxy provides for a longer period. A stockholder may execute a writing authorizing another person or persons to act for such stockholder as proxy. Execution may be accomplished by the stockholder or such stockholder’s authorized officer, director, employee or agent signing such writing or causing such person’s signature to be affixed to such writing by any reasonable means including, but not limited to, by facsimile signature. A stockholder may also authorize another person or persons to act for such stockholder as proxy by transmitting or authorizing the transmission of a telegram, cablegram, or other means of electronic transmission 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 such transmission, provided that any such telegram, cablegram or other means of electronic transmission must either set forth or be submitted with information from which it can be determined that the telegram, cablegram or other electronic transmission was authorized by the stockholder. If it is determined that such telegrams, cablegrams or other electronic transmissions are valid, the inspectors or, if there are no inspectors, such other persons making the determination shall specify the information upon which they relied. Any copy, facsimile telecommunication or other reliable reproduction of the writing or transmission created pursuant to Section 212(c) of the Delaware General Corporation Law 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 telecommunication or other

reproduction shall be a complete reproduction of the entire original writing or transmission. 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. A proxy may be made irrevocable regardless of whether the interest with which it is coupled is an interest in the stock itself or an interest in the corporation generally.

(h) INSPECTORS. The Board of Directors, in advance of any meeting, may, but need not, appoint one or more inspectors of election to act at the meeting or any adjournment thereof. If an inspector or inspectors are not appointed, the person presiding at the meeting may, but need not, appoint one or more inspectors. In case any person who may be appointed as an inspector fails to appear or act, the vacancy may be filled by appointment made by the Board of Directors in advance of the meeting or at the meeting by the person presiding thereat. Each inspector, if any, before entering upon the discharge of duties of inspector, shall take and sign an oath faithfully to execute the duties of inspector at such meeting with strict impartiality and according to the best of such inspector’s ability. The inspectors, if any, shall determine the number of shares of stock outstanding and the voting power of each, the shares of stock represented at the meeting, the existence of a quorum, the validity and effect of proxies, and shall receive votes, ballots, or consents, hear and determine all challenges and questions arising in connection with the right to vote, count and tabulate all votes, ballots, or consents, determine the result, and do such acts as are proper to conduct the election or vote with fairness to all stockholders. On request of the person presiding at the meeting, the inspector or inspectors, if any, shall make a report in writing of any challenge, question, or matter determined by such inspector or inspectors and execute a certificate of any fact found by such inspector or inspectors. Except as may otherwise be required by subsection (e) of Section 231 of the Delaware General Corporation Law, the provisions of that Section shall not apply to the corporation.

(i) QUORUM. Except as otherwise required by law, by the certificate of incorporation or by these Bylaws, the holders of a majority of the outstanding shares of stock shall constitute a quorum at a meeting of stockholders for the transaction of any business. The stockholders present may adjourn the meeting despite the absence of a quorum. At any such adjourned meeting at which the requisite amount of stock entitled to vote shall be represented, any business may be transacted at the meeting as originally noticed.

(j) VOTING. Each share of stock shall entitle the holder thereof to one vote. 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. Any other action shall be authorized by a majority of the votes cast except where the Delaware General Corporation Law prescribes a different percentage of votes and/or a different exercise of voting power, and except as may be otherwise prescribed by the provisions of the certificate of incorporation and these Bylaws. In the election of directors, and for any other action, voting need not be by ballot.

8. STOCKHOLDER ACTION WITHOUT MEETINGS. Except as provided by the certificate of incorporation or as any provision of the Delaware General Corporation Law may

otherwise require, any action required by the Delaware General Corporation Law to be taken at any annual or special meeting of stockholders, or any action which may be taken at any annual or special meeting of stockholders, may be taken without a meeting, without prior notice and without a vote, if a consent 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. A telegram, cablegram or other electronic transmission consenting to an action to be taken and transmitted by a stockholder or proxyholder, or by a person or persons authorized to act for a stockholder or proxyholder, shall be deemed to be written, signed and dated for the purposes of this section, provided that any such telegram, cablegram or other electronic transmission sets forth or is delivered with information from which the corporation can determine that the telegram, cablegram or other electronic transmission was transmitted by the stockholder or proxyholder or by a person or persons authorized to act for the stockholder or proxyholder and the date on which such stockholder or proxyholder or authorized person or persons transmitted such telegram, cablegram or electronic transmission. The date on which such telegram, cablegram or electronic transmission is transmitted shall be deemed to be the date on which such consent was signed. No consent given by telegram, cablegram or other electronic transmission shall be deemed to have been delivered until such consent is reproduced in paper form and until such paper shall be delivered to the corporation by delivery to its principal place of business or an officer or agent of the corporation having custody of the book in which the proceedings of meetings of stockholders are recorded, to the extent and in the manner provided by resolution of the Board of Directors. 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. Action taken pursuant to this paragraph shall be subject to the provisions of Section 228 of the Delaware General Corporation Law.

ARTICLE III

DIRECTORS

1. FUNCTIONS AND DEFINITION. The business and affairs of the corporation shall be managed by or under the direction of the Board of Directors of the corporation. The Board of Directors shall have the authority to fix the compensation of the members thereof. The use of the phrase “whole board” herein refers to the total number of directors, which the corporation would have if there were no vacancies.

2. QUALIFICATIONS AND NUMBER. A director need not be a stockholder, a citizen of the United States, or a resident of the State of Delaware. The initial Board of Directors shall consist of one person. Thereafter, the number of directors may be increased or decreased by action of the stockholders or of the directors.

3. ELECTION AND TERM. The first Board of Directors, unless the members thereof shall have been named in the certificate of incorporation, shall be elected by the incorporator or incorporators and shall hold office until the first annual meeting of stockholders and until their successors are elected and qualified or until their earlier resignation or removal. Any director may resign at any time upon notice given in writing or by electronic transmission to the corporation. Such resignation shall take effect at the time specified therein, or if no time is specified, at the time of its receipt by the President or Secretary of the corporation. The acceptance of a resignation shall not be necessary to make it effective. Thereafter, directors who are elected at an annual meeting of stockholders, and directors who are elected in the interim to fill vacancies and newly created directorships, shall hold office until the next annual meeting of stockholders and until their successors are elected and qualified or until their earlier resignation or removal. Except as the Delaware General Corporation Law may otherwise require, in the interim between annual meetings of stockholders or of special meetings of stockholders called for the election of directors and/or for the removal of one or more directors and for the filling of any vacancy in that connection, newly created directorships and any vacancies in the Board of Directors, including unfilled vacancies resulting from the removal of directors for cause or without cause, may be filled by the vote of a majority of the remaining directors then in office, although less than a quorum, or by the sole remaining director.

4. MEETINGS.

(a) TIME. Meetings shall be held at such time as the Board of Directors shall fix, except that the first meeting of a newly elected Board of Directors shall be held as soon after its election as the directors may conveniently assemble.

(d) NOTICE OR ACTUAL OR CONSTRUCTIVE WAIVER. No notice shall be required for regular meetings for which the time and place have been fixed. Written, oral, or any other mode of notice of the time and place shall be given for special meetings in sufficient time for the convenient assembly of the Board of Directors thereat. Whenever notice is required to be given under the Delaware General Corporation Law, certificate of incorporation or bylaws, a written waiver signed by the person entitled to notice, or a waiver by electronic transmission by the person entitled to notice, whether before or after the time stated therein, shall be deemed equivalent to notice. Attendance of any such person at a meeting shall constitute a waiver of notice of such meeting, except when such person attends a meeting for the express purpose of objecting, at the

beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened. Neither the business to be transacted at, nor the purpose of, any regular or special meeting of the Board of Directors need be specified in any written waiver of notice.

(e) QUORUM AND ACTION. A majority of the whole Board shall constitute a quorum except when a vacancy or vacancies prevents such majority, whereupon a majority of the directors in office shall constitute a quorum, provided, that such majority shall constitute at least one-third of the whole Board. A majority of the directors present, whether or not a quorum is present, may adjourn a meeting to another time and place. Except as herein otherwise provided, and except as otherwise provided by the Delaware General Corporation Law, the vote of the majority of the directors present at a meeting at which a quorum is present shall be the act of the Board. The quorum and voting provisions herein stated shall not be construed as conflicting with any provisions of the Delaware General Corporation Law and these Bylaws which govern a meeting of the Board of Directors held to fill vacancies and newly created directorships in the Board of Directors or action of disinterested directors.

Any member or members of the Board of Directors or of any committee designated by the Board of Directors, may participate in a meeting of the Board of Directors, or any such committee, as the case may be, by means of conference telephone or similar communications equipment by means of which all persons participating in the meeting can hear each other.

5. REMOVAL OF DIRECTORS. Except as may otherwise be provided by the Delaware General Corporation Law, any director or the entire Board of Directors may be removed, with or without cause, at any time by the holders of a majority of all the shares then entitled to vote at an election of directors.

6. COMMITTEES. The Board of Directors may by resolution or resolutions passed by a majority of the Board of Directors designate one or more committees, each committee to consist of one or more of the directors of the corporation. The Board of Directors 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 any member of any such committee or committees, 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 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 of Directors, shall have and may exercise all the powers and authority of the Board of Directors in the management of the business and affairs of the corporation with the exception of any power or authority the delegation of which is prohibited by Section 141 of

the Delaware General Corporation Law, and may authorize the seal of the corporation to be affixed to all papers which may require it.

7. WRITTEN ACTION. Any action required or permitted to be taken at any meeting of the Board of Directors or any committee thereof may be taken without a meeting if all members of the Board of Directors or committee, as the case may be, consent thereto in writing or electronic transmission, and the writing or writings or electronic transmission or transmissions are filed with the minutes of proceedings of the Board of Directors or committee. Such filing shall be in paper form if the minutes are maintained in paper form and shall be in electronic form if the minutes are maintained in electronic form.

INDEMNIFICATION OF DIRECTORS AND OFFICERS

1. INDEMNIFICATION. The Corporation shall indemnify, to the full extent authorized or permitted by law, any person made or threatened to be made a party to any action, suit, or proceeding, whether criminal, civil, administrative, or investigative, by reason of the fact that such person or such person’s testator or intestate is or was a director, officer, or employee of the Corporation or serves or served at the request of the Corporation any other enterprise as a director, officer, or employee.

Expenses incurred by any such person in defending any such action, suit, or proceeding shall be paid or reimbursed by the Corporation promptly upon receipt by it of an undertaking of such person to repay such expenses if it shall ultimately be determined that such person is not entitled to be indemnified by the Corporation. The rights provided to any person by this Bylaw

shall be enforceable against the Corporation by such person who shall be presumed to have relied upon it in serving or continuing to serve as a director, officer, or employee. No amendment of this Bylaw shall impair the rights of any person arising at any time with respect to events occurring prior to such amendment.

For purposes of this Article VIII, Section 1, the term “Corporation” shall include any predecessor of the Corporation and any constituent corporation (including any constituent of a constituent) absorbed by the Corporation in a consolidation or merger; the term “other enterprise” shall include any corporation, partnership, joint venture, trust, or employee benefit plan; service “at the request of the Corporation” shall include service as a director, officer, or employee of the Corporation which imposes duties on, or involves services by, such director, officer, or employee with respect to an employee benefit plan, its participants or beneficiaries; any excise taxes assessed on a person with respect to an employee benefit plan shall be deemed to be indemnifiable expenses; and action by a person with respect to an employee benefit plan which such person reasonably believes to be in the interest of the participants and beneficiaries of such plan shall be deemed to be action not opposed to the best interest of the Corporation.

2. NON-EXCLUSIVE REMEDY.
