Attendance of a person at a meeting shall constitute a waiver of notice of such meeting, except when the person attends 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.

Section 5. Stockholders List. The officer having charge of the stock ledger of the Corporation shall make, at least 10 days before every meeting of stockholders, a complete list of the stockholders entitled to vote at such meeting arranged in alphabetical order, 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 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. Organization. Meetings of the stockholders shall be presided over by the Chairman of the Board, if any, or if none or in the Chairman of the Board’s absence the Chief Executive Officer, if any, or if none or in the Chief Executive Officer’s absence the President, if any, or if none or in the President’s absence a Vice President, or, if none of the foregoing is present, by a chairman to be chosen by the stockholders entitled to vote who are present in person or by proxy at the meeting. The Secretary of the Corporation, or in the 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 presiding officer of the meeting shall appoint any person present to act as secretary of the meeting.

Section 7. Quorum. The holders of record of a majority of the outstanding shares of capital stock entitled to vote, present in person or represented by proxy, shall constitute a quorum at all meetings of the stockholders, except as otherwise provided by the General Corporation Law of the State of Delaware, as amended (the “DGCL”) or by the Certificate of Incorporation. If a quorum is not present, the holders of a majority of the shares present in person or represented by proxy at the meeting, and entitled to vote at the meeting, may adjourn the meeting to another time and/or place. When a specified item of business requires a vote by a class or series (if the Corporation shall then have outstanding shares of more than one class or series) voting as a class or series, the holders of a majority of the shares of such class or series shall constitute a quorum (as to such class or series) for the transaction of such item of business.

Section 8. Adjourned Meetings. When a meeting is adjourned to another time and place, notice need not be given of the adjourned meeting if the time and place thereof are announced at the meeting at which the adjournment is taken. At the adjourned meeting the Corporation may transact any business which might have been transacted at the original meeting. If the adjournment is for more than 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.

Section 9. 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 is not so 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 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 his or her duties, shall take and sign an oath faithfully to execute the duties of the inspector at such meeting with strict impartiality and according to the best of his or her 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, and the validity and effect of proxies, and shall receive votes or ballots, hear and determine all challenges and questions arising in connection with the right to vote, count and tabulate all votes or ballots, 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 if any challenge, question or matter determined by such inspector or inspectors and execute a certificate of any fact found by such inspector or inspectors. No candidate who is a candidate for an office in an election may serve as an inspector at such election.

Section 10. Vote Required. When a quorum is present, the affirmative vote of the majority of shares present in person or represented by proxy at the meeting and entitled to vote on the subject matter shall be the act of the stockholders, unless (i) by express provisions of an applicable law or of the Certificate of Incorporation a different vote is required, in which case such express provision shall govern and control the decision of such question, or (ii) the subject matter is the election of Directors, in which case Section 2 of ARTICLE III hereof shall govern and control the approval of such subject matter.

Section 11. Voting Rights. Except as otherwise provided by the DGCL, the Certificate of Incorporation or any amendments thereto or these Bylaws, every stockholder shall at every meeting of stockholders be entitled to one vote in person or by proxy for each share of capital stock held by such stockholder.

Section 12. Proxies. 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 him or her by proxy, but no such proxy shall be voted or acted upon after three years from its date, unless the proxy provides for a longer period. A duly executed proxy shall be irrevocable if it states that it is irrevocable and if, and only as long as, it is coupled with an interest sufficient in law to support an irrevocable power. 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. Any proxy is suspended when the person executing the proxy is present at a meeting of stockholders and elects to vote, except that when

such proxy is coupled with an interest and the fact of the interest appears on the face of the proxy, the agent named in the proxy shall have all voting and other rights referred to in the proxy, notwithstanding the presence of the person executing the proxy. At each meeting of stockholders, and before any voting commences, all proxies filed at or before the meeting shall be submitted to and examined by the Secretary of the Corporation or a person designated by the Secretary, and no shares may be represented or voted under a proxy that has been found to be invalid or irregular.

Section 13. Conduct of Meetings. 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 by the person presiding over the meeting. The Board of Directors may adopt by resolution such rules and regulations for the conduct of the meeting of stockholders as it shall deem appropriate. Except to the extent inconsistent with such rules or regulations as may be adopted by the Board of Directors, the person presiding over any meeting of stockholders shall have the right and authority to convene the meeting, to prescribe such rules, regulations and procedures and to do all such acts as, in the judgment of such presiding person, are appropriate for the conduct of the meeting. Such rules, regulations or procedures, whether adopted by the Board of Directors or prescribed by the presiding person of the meeting, may include, without limitation, the following: (i) establishment of an agenda or order of business for the meeting; (ii) rules and procedures for maintaining order at the meeting and safety of those present; (iii) limitation on attendance at or participation in the meeting to stockholders of record of the Corporation, their duly authorized and constituted proxies or such other persons as the presiding person at the meeting shall determine; (iv) restrictions on entry to the meeting after the time fixed for commencement thereof; and (v) limitations on the time allotted to questions or comments by participants. The presiding person at the meeting of stockholders, in addition to making any other determinations that may be appropriate to the conduct of the meeting, shall, if the facts warrant, determine and declare to the meeting that a matter or business was not properly brought before the meeting and, if such presiding person shall so declare to the meeting, any such matter or business not properly brought before the meeting shall not be transacted or considered.

Section 14. Business Brought Before a Meeting; Notice.

(a) Annual Meetings of Stockholders.

(1) At an annual meeting of the stockholders, the nominations of persons for election to the Board of Directors and the proposal of other business to be considered by stockholders may only be made if properly brought before the meeting. To be properly brought before an annual meeting, nominations or other business must be (A) specified in the notice of meeting (or any supplement thereto) given by or at the direction of the Board of Directors, (B) brought before the meeting by or at the direction of the Board of Directors or (C) properly brought before the meeting by a stockholder who was a stockholder of record of the Corporation at the time the notice is delivered to the Secretary of the Corporation pursuant to this Section 14(a) and who complies with the notice procedures set forth in this Section 14(a). The provisions of clause (C) of this Section 14(a)(1) shall be the exclusive means for a stockholder to make nominations or submit other business (other than matters properly brought under Rule 14a- 8 promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and included in the Corporation’s notice of meeting) before an annual meeting of stockholders.

(2) For nominations and other business to be properly brought before an annual meeting by a stockholder pursuant to Section 14(a)(1)(C) of ARTICLE II hereof, the stockholder must have given timely notice thereof in writing to the Secretary of the Corporation and any such proposed business other than nominations of persons for election to the Board of Directors must constitute a proper matter for stockholder action. To be timely, a stockholder’s notice must be delivered to or mailed and received by the Secretary of the Corporation at the principal executive offices of the Corporation not earlier than the close of business on the 120th day nor later than the close of business on the 90th day prior to the first anniversary of the preceding year’s annual meeting (or, in the case of the Corporation’s first annual meeting, not earlier than the close of business on the 120th day nor later than the close of the business on the 90th day prior to the date fixed by the Board of Directors for the first annual meeting); provided, however, that in the event that the date of the annual meeting is more than 30 days before or more than 70 days after such anniversary date, notice by the stockholder to be timely must be so received not earlier than the close of business on the 120th day prior to the date fixed by the Board of Directors for such annual meeting nor later than the close of business on the later of (A) the 90th day prior to the date fixed by the Board of Directors for such annual meeting or (B) the 10th day following the date on which public announcement of the date of such meeting is first made by the Corporation. In no event shall any adjournment or postponement of an annual meeting or the public announcement thereof commence a new time period (or extend any time period) for the giving of a stockholder’s notice as set forth herein.

To be in proper form, a stockholder’s notice to the Secretary of the Corporation, whether given pursuant to this Section 14(a)(2) or Section 14(b) of ARTICLE II hereof must: (A) set forth, as to the stockholder giving the notice and the beneficial owner, if any, on whose behalf the nomination or proposal is made (i) the name and address of such stockholder, as they appear on the Corporation’s books, and of such beneficial owner, if any, (ii) (a) the class or series and number of shares of the Corporation which are, directly or indirectly, owned beneficially and of record by such stockholder and such beneficial owner, (b) a description of any agreement, arrangement or understanding entered into, directly or indirectly, by or on behalf of such stockholder or beneficial owner (including any derivative positions, profit interests, options, warrants, convertible securities, stock appreciation or similar rights, and hedging or swap transactions) having an exercise or conversion privilege or a settlement payment or mechanism at a price related to any class or series of shares of the Corporation or with a value derived in whole or in part from the value of any class or series of shares of the Corporation, whether or not such instrument or right shall be subject to settlement in the underlying class or series of capital stock of the Corporation or otherwise, or otherwise intended to or which may have the effect of directly or indirectly mitigating loss with respect to, or managing risk associated with, or providing any direct or indirect opportunity to profit or share in any profit derived from any increase or decrease in the value of shares of the Corporation, (c) any proxy, contract, arrangement, understanding, or relationship (including borrowed or loaned shares) pursuant to which such stockholder directly or indirectly has a right to vote or control the voting of any shares of any security of the Corporation or the effect of which is to increase or decrease, directly or indirectly, the voting power of such stockholder of beneficial owner, (d) any short interest in any security of the Corporation (for purposes of ARTICLE II hereof, a person shall be deemed to have a short interest in a security if such person directly or indirectly, through any contract, arrangement, understanding, relationship or otherwise, has the opportunity to profit or share in any profit derived from any decrease in the value of the subject security) and (e) any rights to dividends on the shares of the Corporation

owned beneficially by such stockholder that are separated or separable from the underlying shares of the Corporation (all of which information described in this Section 14(a)(2)(A)(ii) shall be supplemented by such stockholder and beneficial owner, if any, not later than 10 days after the record date for the meeting to disclose such ownership as of the record date) and (iii) any other information relating to such stockholder and beneficial owner, if any, that would be required to be disclosed in a proxy statement or other filings required to be made in connection with solicitations of proxies for, as applicable, the proposal and/or for the election of directors in a contested election pursuant to Section 14 of the Exchange Act and the rules and regulations promulgated thereunder; (B) if the notice relates to any business other than a nomination of a Director or Directors that the stockholder proposes to bring before the meeting, set forth (i) a brief description of the business desired to be brought before the meeting, the text of the proposal or business (including the text of any resolutions proposed for consideration and the language of any proposed amendment to the Corporation’s Certificate of Incorporation or Bylaws), the reasons for conducting such business at the meeting and any material interest of such stockholder and beneficial owner, if any, in such business and (ii) a description of all agreements, arrangements and understandings between such stockholder and beneficial owner, if any, and any other person or persons (including their names) in connection with the proposal of such business by such stockholder; and (C) set forth, as to each person, if any, whom the stockholder proposes to nominate for election or reelection to the Board (i) all information relating to such person that would be required to be disclosed in a proxy statement or other filings required to be made in connection with solicitations of proxies for election of directors in a contested election pursuant to Section 14 of the Exchange Act and the rules and regulations promulgated thereunder (including such person’s written consent to being named in the proxy statement as a nominee and to serving as a Director if elected), (ii) a statement whether each such nominee, if elected, intends to tender, promptly following such person’s failure to receive the required vote for election or re-election at the next meeting at which such person would face election or re-election, an irrevocable resignation effective upon acceptance of such resignation by the Board of Directors, in accordance with the Corporation’s Policy regarding the Election of Directors and (iii) a description of all direct and indirect compensation and other material monetary agreements, arrangements and understandings during the past three years, and any other material relationships, between or among such stockholder and beneficial owner, if any, and their respective affiliates and associates, or others acting in concert therewith, on the one hand, and each proposed nominee, and his or her respective affiliates and associates, or others acting in concert therewith, on the 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. 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.

(3) Notwithstanding anything in this Section 14 to the contrary, in the event that the number of directors to be elected by the Board of Directors at an annual meeting is increased and there is no public announcement by the Corporation naming the nominees for the additional directorships at least 100 days prior to the first anniversary of the preceding year’s annual meeting, a stockholder’s notice required by this Section 14 shall be considered timely, but only with respect to the nominees for the additional directorships, if it shall be delivered to the Secretary of the Corporation at the principal executive offices of the Corporation not later than the close of business on the 10th 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. 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 (i) by or at the direction of the Board of Directors or (ii) provided that the Board of Directors has determined that directors shall be elected at such meeting, by any stockholder who is a stockholder of record at the time the notice provided for in this Section 14(b) is delivered to the Secretary of the Corporation, who is entitled to vote at the meeting and upon such election and who complies with the notice procedures set forth in this Section 14(b). In the event 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 entitled to vote in such election of directors 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 stockholders notice required by Section 14(a) of ARTICLE II hereof shall be delivered to the Secretary of the Corporation at the principal executive offices of the Corporation not earlier than the close of business on the 120th day prior to the date fixed by the Board of Directors for such special meeting nor later than the close of business on the later of (i) the 90th day prior to the date fixed by the Board of Directors for such special meeting or (ii) the 10th day following the day on which a public announcement is first made of the date of the special meeting and the nominees proposed by the Board of Directors to be elected at such meeting. In no event shall any adjournment or postponement of an annual meeting or the public announcement thereof commence a new time period (or extend any time period) for the giving of a stockholder’s notice as set forth herein.

(c) General Provisions. Only such persons who are nominated in accordance with the procedures set forth in this Section 14 or the Certificate of Incorporation shall be eligible to be elected at an annual or special meeting of stockholders 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 Section 14. Except as otherwise provided by law, the chairman of the meeting shall have the power and duty (i) 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 Section 14 (including whether the stockholder or beneficial owner, if any, on whose behalf the nomination or proposal is made solicited (or is part of a group which solicited) or did not so solicit, as the case may be, proxies in support of such stockholder’s nominee or proposal in compliance with such stockholder’s representation as required by this Section 14) and (ii) if any proposed nomination or business was not made or proposed in compliance with this Section 14, to declare that such nomination shall be disregarded or that such proposed business shall not be transacted. Notwithstanding the foregoing provisions of this Section 14, if the stockholder (or a qualified representative of the stockholder) does not appear at the annual or special meeting of stockholders to present a nomination or 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 Section 14, to be considered a qualified representative of a stockholder, a

person must be a duly authorized officer, manager or partner of such stockholder or 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 transmissions, at the meeting of the stockholders. Notwithstanding the foregoing provisions of this Section 14, 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 Section 14; 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 any requirements applicable to nominations or proposals as to any other business to be considered pursuant to this bylaw (including Sections 14(a)(1)(C) and 14(b) of ARTICLE II hereof), and compliance with Sections 14(a)(1)(C) and 14(b) of ARTICLE II hereof shall be the exclusive means for a stockholder to make nominations or submit other business (other than matters brought properly under and in compliance with Rule 14a-8 under the Exchange Act). Nothing in this Section 14 is in addition to or in lieu of any requirements under, and nothing in this Section 14 shall be deemed to affect any rights of Stockholders to request inclusion of proposals in the Corporation’s proxy statement pursuant to, Rule 14a-8 promulgated under the Exchange Act. For purposes of this Section 14, “public announcement” shall include disclosure in a press release reported by the Dow Jones News Service, Associated Press or comparable 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.

ARTICLE III

DIRECTORS

Section 1. General Powers. The business and affairs of the Corporation shall be managed by or under the direction of the Board of Directors. In addition to such powers as are herein and in the Certificate of Incorporation expressly conferred upon it, the Board of Directors shall have and may exercise all the powers of the Corporation, subject to the provisions of the laws of the State of Delaware, the Certificate of Incorporation and these Bylaws.

Section 2. Number; Election; Term of Office and Remuneration. Each director shall be at least 18 years old. A director need not be a stockholder, a citizen of the United States or a resident of the State of Delaware. The number of Directors which shall constitute the entire Board of Directors shall be such number as may be fixed from time to time by the Board of Directors. Except as provided in Section 4 of this ARTICLE III, each Director shall be elected by the vote of the majority of the votes cast with respect to the Director at any meeting for the election of directors at which a quorum is present; 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 shares represented in person or by proxy at any such meeting and entitled to vote on the election of Directors. For purposes of this section, a majority of the votes cast means that the number of shares voted “for” a Director must exceed the number of votes cast “against” the Director (with “abstentions” and “broker non-votes” not counted as votes cast with respect to that Director). The Nominating and Corporate Governance Committee has adopted and the Board of Directors has approved a Policy Regarding the Election of Directors under which any Director who is not elected shall offer to tender his or her resignation to the Board of Directors. The Nominating and

Corporate Governance Committee (or, if a majority of such committee did not receive the required number of votes for election or re-election, a majority of the independent directors sitting as a special committee appointed by the Board for this purpose (the “Special Nominating Committee”)) shall make a recommendation to the Board of Directors on whether to accept or reject the resignation, or whether other action should be taken. The Board of Directors shall act on any resignation offer thus tendered, considering any and all factors it deems relevant (including but not limited to the recommendation of the Nominating and Corporate Governance Committee or the Special Nominating Committee, as the case may be), and publicly disclose its decision and the reasons therefore within 90 days from the date of the certification of the election results. The Director whose resignation is under consideration shall abstain from participating in any committee or Board of Directors decision regarding his or her resignation, but otherwise will continue to serve during this 90-day period. Each director shall hold office until his or her resignation is accepted, or if such resignation is not accepted, until the next annual meeting and his or her successor is duly elected and qualified. Directors may be paid reimbursement of their expenses, if any, of attendance at each meeting and may be paid a fixed sum for attendance at each meeting of the Board of Directors or a stated compensation as a Director. No such payment shall preclude any Director from serving the Corporation in any other capacity and receiving compensation therefor. Members of special or standing committees may be allowed like compensation for attending committee meetings or acting as a member of such committees.

Section 3. Removal and Resignation. No Director may be removed from office without the affirmative vote of the holders of at least a majority of the voting power of the then outstanding shares of capital stock entitled to vote generally in the election of Directors voting together as a single class; provided, however, that if the holders of any class or series of capital stock are entitled by the provisions of the Certificate of Incorporation (it being understood that any references to the Certificate of Incorporation shall include any duly authorized certificate of designation) to elect one or more Directors, such Director or Directors so elected may be removed without cause only by the vote of the holders of a majority of the outstanding shares of that class or series entitled to vote. Any Director may resign at any time upon written notice to the Corporation.

Section 4. Vacancies. Vacancies and newly created directorships resulting from any increase in the total number of Directors may be filled only in the manner provided in the Certificate of Incorporation.

Section 5. Annual Meetings. The annual meeting of the Board of Directors shall be held without other notice than this Section 5 immediately after, and at the same place as, the annual meeting of stockholders.

Section 6. Other Meetings and Notice. Regular meetings, other than the annual meeting, of the Board of Directors may be held without notice at such time and at such place as shall from time to time be determined by resolution of the Board of Directors. Special meetings of the Board of Directors may be called by the Chairman of the Board, the Chief Executive Officer (if the Chief Executive Officer is a Director) or, upon the written request of at least a majority of the Directors then in office, the Secretary of the Corporation, on at least 24 hours notice to each Director, either personally, by telephone, by mail or by telecopy.

Section 7. Chairman of the Board, Quorum, Required Vote and Adjournment. The Board of Directors shall elect, by the affirmative vote of a majority of the total number of Directors then in office, a Chairman of the Board, who shall preside at all meetings of the stockholders and Board of Directors at which he or she is present and shall have such powers and perform such duties as the Board of Directors may from time to time prescribe. If the Chairman of the Board is not present at a meeting of stockholders or the Board of Directors, the Chief Executive Officer (if the Chief Executive Officer is a Director and is not also the Chairman of the Board) shall preside at such meeting, and, if the Chief Executive Officer is not present at such meeting, a majority of the Directors present at such meeting shall elect one of their members to so preside. A majority of the total number of Directors then in office shall constitute a quorum for the transaction of business. Unless by express provision of an applicable law, the Certificate of Incorporation or these Bylaws a different vote is required, the vote of a majority of Directors present at a meeting at which a quorum is present shall be the act of the Board of Directors. If a quorum shall not be present at any meeting of the Board of Directors, the Directors present thereat may adjourn the meeting from time to time, without notice other than announcement at the meeting, until a quorum shall be present.

Section 8. Committees. The Board of Directors may, by resolution passed by a majority of the total number of Directors then in office, designate one or more committees, each committee to consist of one or more of the Directors of the Corporation, which to the extent provided in such resolution or these Bylaws shall have, and may exercise, the powers of the Board of Directors in the management and affairs of the Corporation, except as otherwise limited by law. 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. Such committee or committees shall have such name or names as may be determined from time to time by resolution adopted by the Board of Directors. Each committee shall keep regular minutes of its meetings and report the same to the Board of Directors upon request.

Section 9. Committee Rules. Each committee of the Board of Directors may fix its own rules of procedure and shall hold its meetings as provided by such rules, except as may otherwise be provided by a resolution of the Board of Directors designating such committee. Unless otherwise provided in such a resolution, the presence of at least a majority of the members of the committee shall be necessary to constitute a quorum. Unless otherwise provided in such a resolution, in the event that a member and that member’s alternate, if alternates are designated by the Board of Directors, of such committee is or are absent or disqualified, 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 place of any such absent or disqualified member.

Section 10. Communications Equipment. Members of the Board of Directors or any committee thereof may participate in and act at any meeting of the Board of Directors or such committee through the use of a conference telephone or other communications equipment by means of which all persons participating in the meeting can hear and speak with each other, and participation in the meeting pursuant to this Section 10 shall constitute presence in person at the meeting.

Section 11. Waiver of Notice and Presumption of Assent. Any member of the Board of Directors or any committee thereof who is present at a meeting shall be conclusively presumed to have waived notice of such meeting except when such member attends 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. Such member shall be conclusively presumed to have assented to any action taken unless his or her dissent shall be entered in the minutes of the meeting or unless his or her written dissent to such action shall be filed with the person acting as the secretary of the meeting before the adjournment thereof or shall be forwarded by registered mail to the Secretary of the Corporation immediately after the adjournment of the meeting. Such right to dissent shall not apply to any member who voted in favor of such action.

Section 12. Action by Written Consent. 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 such committee, as the case may be, consent thereto in writing, and the writing or writings are filed with the minutes of proceedings of the Board of Directors or such committee.

ARTICLE V

CERTIFICATES OF STOCK

Section 1. Form. The shares 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 its 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. Notwithstanding the adoption of such a resolution by the Board of Directors, every holder of stock represented by certificates and, upon request, every holder of uncertificated shares shall be entitled to have a certificate, signed by or in the name of the Corporation by the Chairman or Vice-Chairman of the Board of Directors, or the President or Vice-President, and by the Treasurer or an Assistant Treasurer, or the Secretary or an Assistant Secretary of the Corporation, representing the number of shares registered in certificate form. Any and all signatures on any such certificate may be facsimiles. 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 he were such officer, transfer agent or registrar at the date of issue. The name of the holder of record of the shares represented thereby, with the number of such shares and the date of issue, shall be entered on the books of the Corporation. Upon compliance with provisions restricting the transfer or registration of transfer of shares of stock, if any, shares of capital stock shall be transferable on the books of the Corporation only by the holder of record thereof in person, or by duly authorized attorney, upon surrender and cancellation of certificates in the case of stock represented by a certificate, for a like number of shares, properly endorsed, and the payment of all taxes due thereon.

Section 2. Lost Certificates. The Board of Directors may direct a new certificate or certificates to be issued in place of any certificate or certificates previously 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 Corporation 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 his or her legal representative, to give the Corporation a bond sufficient to indemnify the Corporation against any claim that may be made against the Corporation on account of the loss, theft or destruction of any such certificate or the issuance of such new certificate.

Section 3. Fixing a Record Date for Stockholder Meetings. 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 60 nor less than 10 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 the close of business on the next day preceding the day on which notice is first given. 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.

Section 4. Fixing a Record Date for Other Purposes. In order that the Corporation may determine the stockholders entitled to receive payment of any dividend or other distribution or allotment or any rights or the stockholders entitled to exercise any rights in respect of any change, conversion or exchange of stock, or for the purposes 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 60 days nor less than 10 days prior to such action. If no record date is fixed, the record date for determining stockholders for any such purpose shall be at the close of business on the day on which the Board of Directors adopts the resolution relating thereto.

Section 5. Registered Stockholders. Prior to the surrender to the Corporation of the certificate or certificates for a share or shares of stock with a request to record the transfer of such share or shares, the Corporation may treat the registered owner as the person entitled to receive dividends, to vote, to receive notifications and otherwise to exercise all the rights and powers of an owner. The Corporation 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.

Section 6. Subscriptions for Stock. Unless otherwise provided for in the subscription agreement, subscriptions for shares shall be paid in full at such time, or in such installments and at such times, as shall be determined by the Board of Directors. Any call made by the Board of Directors for payment on subscriptions shall be uniform as to all shares of the same class or as to all shares of the same series. In case of default in the payment of any installment or call when such payment is due, the Corporation may proceed to collect the amount due in the same manner as any debt due the Corporation.

ARTICLE VI

GENERAL PROVISIONS

Section 1. Dividends. Dividends upon the capital stock of the Corporation, subject to the provisions of the Certificate of Incorporation, if any, may be declared by the Board of Directors at any regular or special meeting, in accordance with applicable law. Dividends may be paid in cash, in property or in shares of the capital stock, subject to the provisions of the Certificate of Incorporation. Before payment of any dividend, there may be set aside out of any funds of the Corporation available for dividends such sum or sums as the Directors from time to time, in their absolute discretion, think proper as a reserve or reserves to meet contingencies, or for equalizing dividends, or for repairing or maintaining any property of the Corporation, or any other purpose and the Directors may modify or abolish any such reserve in the manner in which it was created.

Section 2. Checks, Drafts or Orders. All checks, drafts or other orders for the payment of money by or to the Corporation and all notes and other evidences of indebtedness issued in the name of the Corporation shall be signed by such officer or officers, agent or agents of the Corporation, and in such manner, as shall be determined by resolution of the Board of Directors or a duly authorized committee thereof.

Section 3. Contracts. In addition to the powers otherwise granted to officers pursuant to ARTICLE IV hereof, the Board of Directors may authorize any officer or officers, or any agent or agents, of the Corporation to enter into any contract or to execute and deliver any instrument in the name of and on behalf of the Corporation, and such authority may be general or confined to specific instances.

Section 5. Corporate Seal. The Board of Directors may provide a corporate seal which shall be in the form of a circle and shall have inscribed thereon the name of the Corporation and the words “Corporate Seal, Delaware.” The seal may be used by causing it or a facsimile thereof to be impressed or affixed or reproduced or otherwise.

Section 6. Voting Securities Owned By Corporation. Voting securities in any other Corporation held by the Corporation shall be voted by the Chief Executive Officer, the President or a Vice-President, unless the Board of Directors specifically confers authority to vote with respect thereto, which authority may be general or confined to specific instances, upon some other person or officer. Any person authorized to vote securities shall have the power to appoint proxies, with general power of substitution.

Section 7. Waiver of Notice. Whenever any notice whatsoever is required to be given by law, by the Certificate of Incorporation or by these Bylaws, a waiver of such notice either in writing signed by the person entitled to such notice or such person’s duly authorized attorney, or by electronic transmission or any other available method, whether before, at or after the time stated in such waiver, or by the appearance of such person at such meeting in person or by proxy, shall be deemed equivalent to such notice. Any member of the Board of Directors or any committee thereof who is present at a meeting shall be conclusively presumed to have waived notice of such meeting except when such member attends 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. Such member shall be conclusively presumed to have assented to any action taken unless his or her dissent shall be entered in the minutes of the meeting or unless his or her written dissent to such action shall be filed with the person acting as the secretary of the meeting before the adjournment thereof or shall be forwarded by registered mail to the Secretary of the Corporation immediately after the adjournment of the meeting. Such right to dissent shall not apply to any member who voted in favor of such action.

Section 8. Inspection of Books and Records. The Board of Directors shall have power from time to time to determine to what extent and at what times and places and under what conditions and regulations the accounts and books of the Corporation, or any of them, shall be open to the inspection of stockholders; and no stockholder shall have any right to inspect any account or book or document of the Corporation, except as conferred by the laws of the State of Delaware, unless and until authorized so to do by resolution of the Board of Directors or of the stockholders of the Corporation.

Section 9. Section Headings. Section headings in these Bylaws are for convenience of reference only and shall not be given any substantive effect in limiting or otherwise construing any provision herein.

Section 10. Inconsistent Provisions. In the event that any provision of these Bylaws is or becomes inconsistent with any provision of the Certificate of Incorporation, the DGCL or any other applicable law, the provision of these Bylaws shall not be given any effect to the extent of such inconsistency but shall otherwise be given full force and effect.

ARTICLE VII

EXCLUSIVE FORUM

Unless the Corporation consents in writing to the selection of an alternative forum, the Court of Chancery in the State of Delaware (the “Court of Chancery”) shall be the sole and exclusive forum for any stockholder (including a beneficial owner) to bring: (i) any derivative action or proceeding brought on behalf of the Corporation; (ii) any action asserting a claim of breach of fiduciary duty owed by any director, officer or other employee of the Corporation to the Corporation or the Corporation’s stockholders; (iii) any action asserting a claim against the Corporation, its directors, officers or employees arising pursuant to any provision of the DGCL or the Corporation’s Certificate of Incorporation or these Bylaws; or (iv) any action asserting a claim against the Corporation, its directors, officers or employees governed by the internal affairs doctrine, except for, as to each of “(i)” through “(iv)” above, any claim as to which the Court of Chancery determines that there is an indispensable party not subject to the jurisdiction of the Court of Chancery (and the indispensable party does not consent to the personal jurisdiction of the Court of Chancery within ten days following such determination), which is vested in the exclusive jurisdiction of a court or forum other than the Court of Chancery, or for which the Court of Chancery does not have subject matter jurisdiction. Unless the Corporation consents in writing to the selection of an alternative forum, the federal district courts of the United States of America shall, to the fullest extent permitted by law, be the sole and exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933. To the fullest extent permitted by law, any person or entity purchasing or otherwise acquiring or holding any interest in shares of capital stock of the Corporation shall be deemed to have notice of and consented to the provisions of this ARTICLE VII. If any provision or provisions of this ARTICLE VII shall be held to be invalid, illegal or unenforceable as applied to any person or entity or circumstance for any reason whatsoever, then, to the fullest extent permitted by law, the validity, legality and enforceability of such provisions in any other circumstance and of the remaining provisions of this ARTICLE VII (including, without limitation, each portion of any sentence of this ARTICLE VII containing any such provision held to be invalid, illegal or unenforceable that is not itself held to be invalid, illegal or unenforceable) and the application of such provision to other persons or entities and circumstances shall not in any way be affected or impaired thereby.

ARTICLE VIII
