4

other hand, including, without limitation, all information that would be required to be disclosed pursuant to Rule 404 promulgated under Regulation S-K if the stockholder making the nomination and any beneficial owner on whose behalf the nomination is made, if any, or any affiliate or associate thereof or person acting in concert therewith, were the “registrant” for purposes of such rule and the nominee were a director or executive officer of such registrant; and (d) with respect to each nominee for election or reelection to the Board of Directors, include a completed and signed questionnaire, representation and agreement required by Section 2.08 of these Bylaws. The Corporation may require any proposed nominee to furnish such other information as may reasonably be required by the Corporation to determine the eligibility of such proposed nominee to serve as an independent director of the Corporation or that could be material to a reasonable stockholder’s understanding of the independence, or lack thereof, of such nominee.

(iii) Notwithstanding anything in the second sentence of paragraph (a)(ii) of this Bylaw to the contrary, in the event that the number of directors to be elected to the Board of Directors is increased and there is no public announcement by the Corporation naming all of the nominees for director or specifying the size of the increased Board of Directors at least 100 days prior to the first anniversary of the preceding year’s annual meeting, a stockholder’s notice required by this Bylaw shall also be considered timely, but only with respect to nominees for any new positions created by such increase, if it shall be delivered to the Secretary at the principal executive offices of the Corporation not later than the close of business on the 10^th day following the day on which such public announcement is first made by the Corporation.

(b) Special Meetings of Stockholders. Only such business shall be conducted at a special meeting of stockholders as shall have been brought before the meeting pursuant to the Corporation’s notice of meeting or otherwise by or at the direction of the Board of Directors. Nominations of persons for election to the Board of Directors may be made at a special meeting of stockholders at which directors are to be elected pursuant to the Corporation’s notice of meeting (A) by or at the direction of the Board of Directors or (B) provided that the Board of Directors has determined that directors shall be elected at such meeting, by any stockholder of the Corporation who (i) is a stockholder of record at the time of giving of notice provided for in this Bylaw and at the time of the special meeting, (ii) is entitled to vote at the meeting, and (iii) complies with the notice procedures set forth in this Bylaw as to such nomination. The immediately preceding sentence shall be the exclusive means for a stockholder to make nominations (other than matters properly brought under Rule 14a-8 under the Exchange Act and included in the Corporation’s notice of meeting) before a special meeting of stockholders. In the event that the Corporation calls a special meeting of stockholders for the purpose of electing one or more directors to the Board of Directors, any such stockholder may nominate a person or persons (as the case may be) for election to such position(s) as specified in the Corporation’s notice of meeting, if the stockholder’s notice required by paragraph (a)(ii) of this Bylaw with respect to any nomination (including the completed and signed questionnaire, representation and agreement required by Section 2.08 of this Bylaw) shall be delivered to the Secretary at the principal executive offices of the Corporation not earlier than the close of business on the 120^th day prior to the date of such special meeting and not later than the close of business on the later of the 90^th day prior to the date of such special meeting or, if the first public announcement of the date of such special meeting is less than 100 days prior to the date of such special meeting, the 10^th day following the day on which public announcement is first made of the date of the special meeting and of the nominees proposed by the Board of Directors to be elected at such meeting. In no event shall any adjournment or postponement of a special meeting or the announcement thereof commence a new time period for the giving of a stockholder’s notice as described above.

(c) General.

(i) Only such persons who are nominated in accordance with the procedures set forth in this Bylaw shall be eligible to serve as directors and only such business shall be conducted at a meeting of stockholders as shall have been brought before the meeting in accordance with the procedures set forth in this Bylaw. Except as otherwise provided by law, the Certificate of Incorporation or these Bylaws, the Chairman of the meeting shall have the power and duty to determine whether a nomination or any business proposed to be brought before the meeting was made or proposed, as the case may be, in accordance with the procedures set forth in this Bylaw and, if any proposed nomination or business is not in compliance with this Bylaw, to declare that such defective proposal or nomination shall be disregarded. Unless otherwise required by law, if the stockholder (or a qualified representative of the stockholder) does not appear at the annual or special meeting of stockholders of the Corporation to make a nomination or present a proposal of other business, such nomination shall be disregarded and such proposed business shall not be transacted, notwithstanding that proxies in respect of such vote may have been received by the Corporation. For purposes of this Bylaw, to be considered a qualified representative of the stockholder, a person must be authorized by a writing executed by such stockholder or an electronic transmission delivered by such stockholder to act for such stockholder as proxy at the meeting of stockholders and such person must produce such writing or electronic transmission, or a reliable reproduction of the writing or electronic transmission, at the meeting of stockholders.

(ii) For purposes of this Bylaw, “public announcement” shall mean disclosure in a press release reported by a national news service or in a document publicly filed by the Corporation with the Securities and Exchange Commission pursuant to Section 13, 14 or 15(d) of the Exchange Act and the rules and regulations promulgated thereunder.

(iii) Notwithstanding the foregoing provisions of this Bylaw, a stockholder shall also comply with all applicable requirements of the Exchange Act and the rules and regulations thereunder with respect to the matters set forth in this Bylaw; provided, however, that any references in these Bylaws to the Exchange Act or the rules promulgated thereunder are not intended to and shall not limit the requirements applicable to nominations or proposals as to any other business to be considered pursuant to paragraph (a)(i)(C) or paragraph (b) of this Bylaw. Nothing in this Bylaw 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 Exchange Act or (ii) of the holders of any series of Preferred Stock if and to the extent provided for under law, the Certificate of Incorporation or these Bylaws. Subject to Rule 14a-8 under the Exchange Act, nothing in these Bylaws shall be construed to permit any stockholder, or give any stockholder the right, to include or have disseminated or described in the Corporation’s proxy statement any nomination of director or directors or any other business proposal.

Section 2.08 Submission of Questionnaire, Representation and Agreement. To be eligible to be a nominee for election or reelection as a director of the Corporation and qualified to serve as a director, a person must deliver (in accordance with the time periods prescribed for delivery of notice under Section 2.07 of these Bylaws) to the Secretary at the principal executive offices of the Corporation a written questionnaire with respect to the background and qualification of such person and the background of any other person or entity on whose behalf the nomination is being made (which questionnaire shall be provided by the Secretary upon written request) and a written representation and agreement (in the form provided by the Secretary upon written request) that such person (A) is not and will not become a party to (1) any agreement, arrangement or understanding with, and has not given any commitment or assurance to, any person or entity as to how such person, if elected as a director of the

6

Corporation, will act or vote on any issue or question (a “Voting Commitment”) that has not been disclosed to the Corporation or (2) any Voting Commitment that could limit or interfere with such person’s ability to comply, if elected as a director of the Corporation, with such person’s fiduciary duties under applicable law, (B) is not and will not become a party to any agreement, arrangement or understanding with any person or entity other than the Corporation with respect to any direct or indirect compensation, reimbursement or indemnification in connection with service or action as a director that has not been disclosed therein and (C) in such person’s individual capacity and on behalf of any person or entity on whose behalf the nomination is being made, would be in compliance, if elected as a director of the Corporation, and will comply with all applicable publicly disclosed corporate governance, conflict of interest, confidentiality and stock ownership and trading policies and guidelines of the Corporation.

Section 2.09 Procedure for Election of Directors; Required Vote. Subject to the rights of the holders of any series of Preferred Stock to elect directors under specified circumstances, at all meetings of the stockholders at which directors are to be elected, a plurality of the votes cast by stockholders entitled to vote for the election of such directors shall be sufficient to elect such directors. Except as otherwise provided by applicable law, the Certificate of Incorporation, these Bylaws, the rules or regulations of any stock exchange applicable to the Corporation, or any regulation applicable to the Corporation or its stockholders, in all matters other than the election of directors, the affirmative vote of a majority in voting power of the shares present in person or represented by proxy at the meeting and entitled to vote on the matter shall be the act of the stockholders.

Section 2.10 Inspectors of Elections; Opening and Closing the Polls. The Board of Directors by resolution shall appoint one or more inspectors, which inspector or inspectors may include individuals who serve the Corporation in other capacities, including, without limitation, as officers, employees, agents or representatives, to act at the meetings of stockholders and make a written report thereof. One or more persons may be designated as alternate inspectors to replace any inspector who fails to act. If no inspector or alternate has been appointed to act or is able to act at a meeting of stockholders, the chairman of the meeting shall appoint one or more inspectors to act at the meeting. Each inspector, before discharging 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 have the duties prescribed by law.

The Chairman of the meeting shall fix and announce at the meeting the date and time of the opening and the closing of the polls for each matter upon which the stockholders will vote at a meeting.

Section 2.11 Action Without a Meeting. Only to the extent permitted under the Certificate of Incorporation, any action permitted or required to be taken at a meeting of stockholders, may be taken without a meeting, without prior notice and without a vote, if a consent or consents in writing, setting forth the action so taken, shall be signed by or on behalf of the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted and shall be delivered to the Corporation by delivery to its registered office in the State of Delaware, its principal place of business, or an officer or agent of the Corporation having custody of the book in which proceedings of meetings of stockholders are recorded. Delivery made to the Corporation’s registered office shall be by hand or by certified or registered mail, return receipt requested. An 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 these Bylaws, provided that any such electronic transmission sets forth or is delivered with information from which the Corporation can determine (A) that the electronic transmission was transmitted by the stockholder or proxyholder or by a person or persons authorized to

7

act for the stockholder or proxyholder and (B) the date on which such stockholder or proxyholder or authorized person or persons transmitted such electronic transmission. Any consent by means of electronic transmission shall be deemed to have been signed on the date on which such electronic transmission was transmitted. No consent given by electronic transmission shall be deemed to have been delivered until such consent is reproduced in paper form and until such paper form shall be delivered to the Corporation by delivery to its registered office in the State of Delaware, its principal place of business or an officer or agent of the Corporation having custody of the book or books in which proceedings of meetings of stockholders are recorded. Delivery of a consent given by electronic transmission made to the Corporation’s registered office shall be made by hand or by certified or registered mail, return receipt requested. Notwithstanding the foregoing limitations on delivery, consents given by electronic transmission may be otherwise delivered to the principal place of business of the Corporation or to an officer or agent of the Corporation having custody of the book or books in which proceedings of meetings of stockholders are recorded if, to the extent, and in the manner provided by resolution of the Board of Directors of the Corporation. Any copy, facsimile, or other reliable reproduction of a consent in writing (or reproduction in paper form of a consent by electronic transmission) may be substituted or used in lieu of the original writing (or original reproduction in paper form of a consent by electronic transmission) for any and all purposes for which the original consent could be used, provided that such copy, facsimile, or other reproduction shall be a complete reproduction of the entire original writing (or original reproduction in paper form of a consent by electronic transmission). Prompt notice of the taking of corporate action without a meeting by less than a unanimous written consent shall be given by the Secretary to those stockholders who have not consented in writing and who, if the action had been taken at a meeting, would have been entitled to notice of the meeting if the record date for such meeting had been the date that written consents signed by a sufficient number of the holders to take the action were delivered to the Corporation.

Section 2.12 Effectiveness of Written Consent. Every written consent shall bear the date of signature of each stockholder who signs the consent and no written consent shall be effective to take the corporate action referred to therein unless, within 60 days of the earliest dated written consent received in accordance with Section 2.11, a written consent or consents signed by a sufficient number of holders to take such action are delivered to the Corporation in the manner prescribed in Section 2.11.

Section 2.13 Remote Meetings. If authorized by the Board of Directors in its sole discretion, and subject to such 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:

(a) participate in a meeting of stockholders; and

(b) 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 (i) 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, (ii) 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 (iii) 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.

Subject to the rights, if any, of the holders of any series of Preferred Stock to elect directors under specified circumstances, any vacancy resulting from the death, resignation, removal or disqualification of any director or other cause, or any newly created directorship resulting from any increase in the authorized number of directors, shall be filled exclusively by a majority of the directors then in office, though less than a quorum, or a sole remaining director. Each director so elected shall hold office until the next election of the class for which such director shall have been chosen and until his or her successor shall be elected and shall be qualified, or until his or her earlier death, resignation, removal or disqualification.

Section 3.11 Executive and Other Committees. The Board of Directors may, by resolution adopted by a majority of the Whole Board, designate an Executive Committee to exercise, subject to applicable provisions of law, all the powers of the Board of Directors in the management of the business and affairs of the Corporation when the Board of Directors is not in session, including without limitation the power to declare dividends, to authorize the issuance of the Corporation’s capital stock and to adopt a certificate of ownership and merger pursuant to Section 253 of the General Corporation Law of the State of Delaware, and may, by resolution similarly adopted, designate one or more other committees. The Executive Committee and each such other committee shall consist of two (2) or more directors of the Corporation. The Board of Directors may designate one (1) or more directors as alternate members of any committee, who may replace any absent or disqualified member at any meeting of the committee. Any such committee, other than the Executive Committee (the powers of which are expressly provided for herein), may to the extent permitted by law exercise such powers and shall have such responsibilities as shall be specified in the designating resolution. In the absence or disqualification of any member of such committee or committees, the member or members thereof present at any meeting and not disqualified from voting, whether or not constituting 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. Each committee shall keep written minutes of its proceedings and shall report such proceedings to the Board of Directors when required.

10

A majority of any committee may determine its action and fix the time and place of its meetings, unless the Board of Directors shall otherwise provide. Notice of such meetings shall be given to each member of the committee in the manner provided for in Section 3.08 of these Bylaws. The Board of Directors shall have power at any time to fill vacancies in, to change the membership of, or to dissolve any such committee.

Section 3.12 Action Without Meeting. Unless otherwise restricted by the Certificate of Incorporation, 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 of Directors or any committee thereof, as the case may be, consent thereto in writing or by electronic transmission, and the writing or writings or electronic transmission or transmissions are filed with the minutes or proceedings of the Board of Directors or committee.

Section 3.13 Fees and Compensation. Unless otherwise restricted by the Certificate of Incorporation or these Bylaws, the Board of Directors may, if it so desires, authorize members of the Board of Directors to be compensated for their expenses, if any, of attendance at each regular or special meeting of the Board of Directors. Such compensation may, in the Board’s discretion, also include a fixed sum for each meeting and an annual fee for serving as a director, such as may be allowed by resolution of the Board of Directors. Directors who are officers or employees of the Corporation may receive, if the Board desires, fees for serving as directors. Nothing herein contained shall be construed to preclude any director from serving the Corporation in any other capacity and receiving compensation therefor.

ARTICLE V. CAPITAL STOCK

Section 5.01 Certificated and Uncertificated Stock; Transfers.

(a) Subject to clause (d) below, the shares of stock of the Corporation shall be represented by certificates, provided that the Board of Directors may provide by resolution or resolutions that some or all of any or all classes or series of the Corporation’s stock shall be uncertificated shares. Any such resolution shall not apply to shares represented by a certificate until such certificate is surrendered to the Corporation.

(b) The shares of the stock of the Corporation shall be transferred on the books of the Corporation, in the case of certificated shares of stock, by the holder thereof in person or by such holder’s attorney duly authorized in writing, upon surrender for cancellation of certificate(s) for at least the same number of shares, with an assignment and power of transfer endorsed thereon or attached thereto, duly executed, with such proof of the authenticity of the signature as the Corporation or its agents may reasonably require; and, in the case of uncertificated shares of stock, upon receipt of proper transfer instructions from the registered holder of the shares or by such person’s attorney duly authorized in writing, and upon compliance with appropriate procedures for transferring shares in uncertificated form. No transfer of stock shall be valid as against the Corporation for any purpose until it shall have been entered in the stock records of the Corporation by an entry showing from and to whom transferred.

(c) Every holder of stock in the Corporation represented by certificates shall be entitled to have a certificate signed by, or in the name of the Corporation by, the Chairman of the Board or the Vice Chairman of the Board, or the President or a Vice President, and by the Treasurer or an Assistant Treasurer or the Secretary or an Assistant Secretary, certifying the number and class of shares of stock of the Corporation owned by such holder. Any or all of the signatures on such certificates may be an electronic signature. In case any officer, transfer agent or registrar who has signed or whose electronic signature has been placed upon a certificate has 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 or she were such officer, transfer agent or registrar at the date of issue.

(d) Notwithstanding anything to the contrary in these Bylaws, at all times that the Corporation’s stock is listed on a stock exchange, the shares of the stock of the Corporation shall comply with all direct registration system eligibility requirements established by such exchange, including any requirement that shares of the Corporation’s stock be eligible for issue in uncertificated or book-entry form. All issuances and transfers of shares of the Corporation’s stock

13

shall be entered on the books of the Corporation with all information necessary to comply with such direct registration system eligibility requirements, including the name and address of the person to whom the shares of stock are issued, the number of shares of stock issued and the date of issue. The Board of Directors shall have the power and authority to make such rules and regulations as it may deem necessary or proper concerning the issue, transfer and registration of shares of stock of the Corporation in both the certificated and uncertificated form.

Section 5.02 Last, Stolen, Mutilated or Destroyed Certificates. As a condition to the issue of a new certificate of stock or uncertificated shares in the place of any certificate theretofore issued and alleged to have been lost, stolen, mutilated or destroyed, the Board of Directors, in its discretion, may require the owner of any such certificate, or such owner’s legal representatives, to give the Corporation a bond in such sum and in such form as it may direct or to otherwise indemnify the Corporation against any claim that may be made against it on account of the alleged loss, theft, mutilation or destruction of any such certificate or the issuance of such new certificate or uncertificated shares. Proper evidence of such loss, theft, mutilation or destruction shall be procured for the Board of Directors, if required. The Board of Directors, in its discretion, may authorize the issuance of such new certificate without any bond when in its judgment it is proper to do so.

Section 5.03 Record Owners. Prior to the surrender to the Corporation of the certificate or certificates for shares of stock, or notification to the Corporation of the transfer of uncertificated shares with a request to record the transfer of such share or shares, 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, to vote and to receive notifications as such owner, and otherwise to exercise all of the rights and powers of an owner of such 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 required by law.

Section 5.04 Transfer and Registry Agents. The Corporation may from time to time maintain one or more transfer offices or agencies and registry offices or agencies at such place or places as may be determined from time to time by the Board of Directors.

Section 5.05 Record Date.

(a) In order that the Corporation may determine the stockholders entitled to notice of and 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 and which record date, unless otherwise required by law, shall not be more than 60 nor less than 10 days before the date of such meeting. If no such record date is fixed by the Board of Directors, then the record date shall, unless otherwise required by law, be at the close of business on the day next preceding the day on which notice of such meeting 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.

(b) In order that the Corporation may determine the stockholders entitled to receive payment of any dividend or distribution, or the date for the allotment of rights, or the date when any exercise of any rights, change or conversion or exchange of capital stock shall go into effect, the Board of Directors may fix a record date, which record date shall not precede the date upon which the record date fixing the record date is adopted and which record date shall not be more than 60 days prior to such action. If no such record date is fixed, the record date for determining stockholders for any such purpose shall be at the close of business on the day on which the Board of Directors adopts the resolution relating thereto.

14

(c) In order that the Corporation may determine the stockholders entitled to express 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 record date shall not be more than 10 days after the date upon which the resolution fixing the record date is adopted by the Board of Directors. If no record date for determining stockholders entitled to express consent to corporate action in writing without a meeting has been fixed by the Board of Directors (i) when no prior action of the Board of Directors is required by law, the record date for such purpose 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 in accordance with applicable law, and (ii) if prior action by the Board of Directors is required by law, the record date for such purpose shall be at the close of business on the day on which the Board of Directors adopts the resolution taking such prior action.

ARTICLE VI. AMENDMENTS

Section 6.01 Amendments by Stockholders. These Bylaws may be altered, amended or repealed and new Bylaws may be added by the stockholders at any annual meeting of the stockholders or at any special meeting thereof if notice of the proposed alteration, amendment, repeal or addition is contained in the notice of such special meeting, by the affirmative vote of the holders of a majority of the stock entitled to vote thereat.

Section 6.02 Amendments by the Board of Directors. The Board of Directors may adopt, amend or repeal these Bylaws by the affirmative vote of a majority of the Board of Directors at any regular or special meeting of the Board.

Section 7.03 Dividends. Subject to the provisions of the Certificate of Incorporation, the Board of Directors may, out of funds legally available therefor, declare dividends upon the capital stock of the Corporation as and when they deem expedient, in accordance with law. Before declaring any dividend there may be set apart out of any funds of the Corporation available for dividends such sum or sums as the directors from time to time in their discretion may deem proper for working capital or as a reserve fund to meet contingencies or for equalizing dividends or for such other purposes as the directors may deem conducive to the interests of the Corporation. The Board of Directors may abolish any such reserve at any time.

Section 7.04 Waiver of Notice and Consent. Whenever any notice is required to be given under the provisions of the General Corporation Law of the State of Delaware, the Certificate of Incorporation or these Bylaws, a written waiver, signed by the person or persons entitled to such notice, or a waiver by electronic transmission by the person entitled to notice, whether before or after the time

15

stated therein, shall be deemed equivalent to the giving of such notice. Attendance of a person at a meeting shall constitute a waiver of notice of such meeting, except when the 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 annual, regular or special meeting of the stockholders or the Board of Directors or committee thereof need be specified in any waiver of notice of such meeting.

Section 7.05 Time Periods. Except as otherwise provided in these Bylaws, in applying any provision of these Bylaws which requires that an act be done or not be done a specified number of days prior to an event or that an act be done during a period of a specified number of days prior to an event, calendar days shall be used, the day of the doing of the act shall be excluded and the day of the event shall be included.

Section 7.06 Contracts. Except as otherwise required by law, the Certificate of Incorporation or these Bylaws, any contracts or other instruments may be executed and delivered in the name and on the behalf of the Corporation by such officer or officers of the Corporation as the Board of Directors may from time to time direct. Such authority may be general or confined to specific instances as the Board of Directors may determine. The Chairman of the Board, the Chief Executive Officer, each President, the Chief Financial Officer or any Vice President may execute bonds, contracts, deeds, leases and other instruments to be made or executed for or on behalf of the Corporation. Subject to any restrictions imposed by the Board of Directors or the Chairman of the Board, the Chief Executive Officer, each President, the Chief Financial Officer or any Vice President of the Corporation may delegate contractual powers to others under his or her jurisdiction, it being understood, however, that any such delegation of power shall not relieve such officer of responsibility with respect to the exercise of such delegated power.
