EFFECTIVE AS OF [            ]

Article I

Stockholders’ Meetings.

1. Place of Meetings. Meetings of the stockholders shall be held at such time and place within or without the State of Delaware as may be designated by the Board of Directors.

2. Annual Meetings. The annual meeting of the stockholders shall be held on such date and at such time and place as the Board of Directors may designate. At such annual meeting, the stockholders shall elect directors, in accordance with the requirements of the Certificate of Incorporation, and transact such other business as may properly be brought before the meeting.

3. Special Meetings. Except as otherwise provided by law, special meetings of the stockholders for any purpose or purposes may only be called by the Chair of the Board, and shall be called by the Chair of the Board or the Secretary at the request in writing of a majority of the Board of Directors.

4. Notice. Written notice of an annual or special meeting shall be given to each stockholder entitled to vote thereat, not less than ten nor more than sixty days prior to the meeting. The date, place and time of the meeting shall be stated in the notice of such meeting delivered to or mailed to stockholders. If mailed, such notice shall be deemed to be given when deposited in the mail, postage prepaid, directed to the stockholder at his address as it appears on the records of the Corporation.

5. Quorum; Adjournments; Postponement. The holders of stock representing a majority of the voting power of all shares of stock issued and outstanding and entitled to vote, present in person or represented by proxy, shall be requisite for and shall constitute a quorum of all meetings of the stockholders, except as otherwise provided by law, by the Certificate of Incorporation or by these By-laws. In the absence of a quorum, holders of stock representing a majority of the voting power of all shares present in person or represented by proxy at the meeting, or the Chair of the meeting, may adjourn any meeting of stockholders, annual or special, from time to time, to reconvene at the same or some other place, until a quorum shall be present or represented. Notice need not be given of any such adjourned meeting if the time and place thereof are announced at the meeting at which the adjournment is taken. Furthermore, after the meeting has been duly organized, the Chair of the meeting may adjourn any meeting of stockholders, annual or special, from time to time, to reconvene at the same or some other place, and notice need not be given of any such adjourned meeting if the time and 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; provided, however, that if the adjournment is for more than thirty (30) days, or if after the adjournment a new record date is fixed for the

adjourned meeting, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting. At the adjourned meeting the Corporation may transact any business which might have been transacted at the original meeting. Any previously scheduled meeting of stockholders may be postponed by the Board of Directors prior to the date previously scheduled for such meeting and the Corporation shall publicly announce such postponement.

6. Voting; Proxies. At each meeting of the stockholders of the Corporation, every stockholder having the right to vote may authorize another person to act for him by proxy. Such authorization must be in writing and executed by the stockholder or his authorized officer, director, employee, or agent. To the extent permitted by law, a stockholder may authorize another person or persons to act for him as proxy by transmitting or authorizing the transmission of an 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 the electronic transmission either sets forth or is submitted with information from which it can be determined that the electronic transmission was authorized by the stockholder. A copy, facsimile transmission or other reliable reproduction of a writing or transmission authorized by this paragraph 6 of Article I may be substituted for or used in lieu of the original writing or electronic transmission for any and all purposes for which the original writing or transmission could be used, provided that such copy, facsimile transmission or other reproduction shall be a complete reproduction of the entire original writing or transmission. No proxy authorized hereby shall be voted or acted upon more than 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 stockholder may revoke any proxy which is not irrevocable by attending the meeting and voting in person or by filing an instrument in writing revoking the proxy or by filing a subsequent duly executed proxy with the Secretary of the Corporation. The vote for directors shall be by ballot. No ballot, proxies or votes, nor any revocations thereof or changes thereto shall be accepted after the time set for the closing of the polls pursuant to paragraph 10 of Article I of these By-laws unless the Court of Chancery upon application of a stockholder shall determine otherwise. Each proxy shall be delivered to the inspectors of election prior to or at the meeting. Unless a greater number of affirmative votes is required by the Certificate of Incorporation, these By-laws, the rules or regulations of any stock exchange applicable to the Corporation, or as otherwise required by law or pursuant to any regulation applicable to the Corporation, if a quorum exists at any meeting of stockholders, stockholders shall have approved any matter, other than the election of directors, if the votes cast by stockholders present in person or represented by proxy at the meeting and entitled to vote on the matter in favor of such matter exceed the votes cast by such stockholders against such matter. A nominee for director shall be elected to the Board of Directors if the votes cast for such nominee’s election exceed the votes cast against such nominee’s election; provided, however, that directors shall be elected by a plurality of the votes cast at any meeting of stockholders for which the Secretary of the Corporation determines that the number of nominees exceeds the number of directors to be elected as of the record date for such meeting. If directors are to be elected by a plurality of the votes cast, stockholders shall not be permitted to vote against a nominee.

7. Inspectors of Election. The Corporation shall, in advance of any meeting of stockholders, appoint one or more inspectors of election to act at the meeting and make a written report thereof. The Corporation may designate one or more persons as alternate inspectors to replace any inspector who fails to act. In the event that no inspector so appointed or designated is able to act at a meeting of stockholders, the Chair of the meeting shall appoint one or more inspectors to act at the meeting. Each inspector, before entering upon the discharge of his duties, shall take and sign an oath faithfully to execute the duties of inspector with strict impartiality and according to the best of his ability. The inspector or inspectors so appointed or designated shall (i) ascertain the number of shares of capital stock of the Corporation outstanding and the voting power of each such share, (ii) determine the shares of capital stock of the Corporation present or represented at the meeting and the validity of proxies and ballots, (iii) count all votes and ballots, (iv) determine and retain for a reasonable period a record of the disposition of any challenges made to any determination by the inspectors, and (v) certify their determination of the number of shares of capital stock of the Corporation present or represented at the meeting and such inspectors’ count of all votes and ballots. Such certification shall specify such other information as may be required by law. In determining the validity and counting of proxies and ballots cast at any meeting of stockholders of the Corporation, the inspectors may consider such information as is permitted by applicable law. No person who is a candidate for an office at an election may serve as an inspector at such election.

8. List of Stockholders Entitled to Vote. At least ten days before every meeting of the stockholders a complete list of the stockholders entitled to vote at said meeting, arranged in alphabetical order, with the post office address of each, and the number of shares held by each, shall be prepared by the Secretary. Such list shall be open to the examination of any stockholder for any purpose germane to the meeting, during ordinary business hours at the Corporation’s headquarters or 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, and shall be produced and kept at the time and place of meeting during the whole time thereof and subject to the inspection of any stockholder who may be present. The original or duplicate stock ledger shall be provided at the time and place of each meeting and shall be the only evidence as to who are the stockholders entitled to examine the list of stockholders or to vote in person or by proxy at such meeting.

9. Organization. Meetings of stockholders shall be presided over by the Chair of the Board, or in his absence by a Chair designated by the Board of Directors, or in the absence of such designation by a Chair chosen at the meeting. The Secretary shall act as secretary of the meeting, but in his absence the Chair of the meeting may appoint any person to act as secretary of the meeting.

10. Conduct of Meetings. 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 shall be announced at such meeting by the Chair of the meeting. The Board of Directors of the Corporation may adopt by resolution such rules or regulations for the conduct of meetings of stockholders as it shall deem appropriate. Except to the extent inconsistent with such rules and regulations as adopted by the Board of Directors, the Chair of any meeting of stockholders shall have the right and authority to prescribe such rules, regulations and procedures and to do all such acts as, in the judgment of such Chair, are appropriate for the proper conduct of the meeting. Such rules,

3

regulations or procedures, whether adopted by the Board of Directors or prescribed by the Chair of the meeting, may include, without limitation, the following: (1) the establishment of an agenda or order of business for the meeting; (2) rules and procedures for maintaining order at the meeting and the safety of those present; (3) limitations 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 Chair shall permit; (4) restrictions on entry to the meeting after the time fixed for the commencement thereof; and (5) limitations on the time allotted to questions or comments by participants. The Chair of any meeting shall determine all matters relating to the conduct of the meeting, including, but not limited to, determining whether any nomination or other item of business has been properly brought before the meeting in accordance with these By-laws, and if the Chair should so determine and declare that any nomination or other item of business has not been properly brought before the meeting, then such business shall not be transacted at such meeting. Unless and to the extent determined by the Board of Directors or the Chair of the meeting, meetings of stockholders shall not be required to be held in accordance with rules of parliamentary procedure.

11. Fixing Date for Determination of Stockholders of Record. In order that the Corporation may determine the stockholders entitled to notice of or to vote at any meeting of the stockholders or any adjournment or postponement thereof, or entitled to receive payment of any dividend or other distribution or allotment of any rights, or entitled to exercise any rights in respect of any change, conversion or exchange of stock or for the purpose of any other lawful action, the Board 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: (1) in the case of determination of stockholders entitled to vote at any meeting of stockholders or adjournment or postponement thereof, shall, unless otherwise required by law, not be more than sixty nor less than ten days before the date of such meeting; and (2) in the case of any other action, shall not be more than sixty days prior to such other action. If no record date is fixed: (a) 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 date next preceding the day on which the meeting is held; and (b) the record date for determining stockholders for any other purpose shall be at the close of business on the day on which the Board of Directors adopts the resolution relating, thereto. A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment or postponement of the meeting; provided, however, that the Board of Directors may fix a new record date for the adjourned or postponed meeting.

12. Consent of Stockholders in Lieu of Meeting. Any action required or permitted to be taken at any annual or special meeting of stockholders of the Corporation 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 the holders of outstanding capital 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 of the capital stock entitled to vote thereon were present and voted, only as provided in and for the period specified in Article TENTH of the Certificate of Incorporation. Such consents 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 the

4

stockholders are recorded. Delivery made to the Corporation’s registered office shall be by hand or by certified or registered mail, return receipt requested. 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 sixty (60) days after the earliest dated consent delivered in the manner required by this paragraph 12 of Article I to the Corporation, written consents signed by a sufficient number of holders to take action are 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 the stockholders are recorded. 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 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 holders to take the action were delivered to the Corporation as provided above in this paragraph 12 of Article I.

13. Notice of Stockholder Proposal. At an annual meeting of the stockholders, only such business shall be conducted as shall have been properly brought before the meeting. To be properly brought before an annual meeting 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) otherwise properly brought before the meeting by or at the direction of the Board of Directors, or (c) otherwise properly brought before the meeting by a stockholder (i) who is a stockholder of record on the date of the giving of the notice provided for in this paragraph 13 of this Article I and on the record date for the determination of stockholders entitled to notice of and to vote at such annual meeting and (ii) who complies with the notice procedures set forth in this paragraph 13 of this Article I. For business to be properly brought before an annual meeting by a stockholder (other than the nomination of a person for election as a director, which is governed by paragraphs 16, 17 and 18 of Article II of these By-laws), the stockholder intending to propose the business (the “Proponent”) must have given timely notice thereof in proper written form to the Secretary of the Corporation. To be timely, a Proponent’s notice must be delivered to or mailed (including by courier) and received by the Secretary at the principal executive offices of the Corporation not less than 90 days nor more than 120 days in advance of the anniversary of the previous year’s annual meeting; provided, however, that in the event the annual meeting is called for a date that is not within 25 days before or after such anniversary date, notice by the stockholder in order to be timely must be so received no later than the close of business on the 10th day following the date on which such notice of the date of the annual meeting was mailed or the public disclosure of the date of the annual meeting was made, whichever first occurs. If no annual meeting was held in the previous year, then a shareholder’s notice, in order to be considered timely, must be received by the Secretary of the Corporation not later than the later of the close of business on the 90th day prior to such annual meeting or the 10th day following the day on which notice of the date of the annual meeting was mailed or public disclosure of such date was made. In no event shall the adjournment or postponement of the annual meeting, or the public announcement of such an adjournment or postponement, commence a new time period (or extend any time period) for the giving of a stockholder’s notice as described above. (For

5

purposes of these By-laws, public disclosure shall be deemed to include a disclosure made in a press release reported by the Dow Jones News Services, Associated Press or a comparable national news service or in a document filed by the Corporation with the Securities and Exchange Commission pursuant to Section 13, 14 or 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)). To be in proper written form, a Proponent’s notice to the Secretary must set forth: (a) as to each matter the Proponent proposes to bring before the annual meeting, a brief description of the business desired to be brought before the annual meeting and the reasons for conducting such business at the annual meeting, and (b) as to the Proponent and the beneficial owner, if any, on whose behalf the proposal is being made, (i) the name and address of each such person, and of any holder of record of the Proponent’s shares as they appear on the Corporation’s books, (ii) (A) the class and number of all shares of capital stock of the Corporation that are owned by each such person (beneficially and of record) and owned by any holder of record of each such person’s shares, as of the date of the Proponent’s notice, and a representation that the Proponent will notify the Corporation in writing of the class and number of such shares owned of record and beneficially by each such person as of the record date for the meeting not later than five business days following the later of the record date or the date notice of the record date is first publicly disclosed and (B) the name of each nominee holder of shares of stock of the Corporation owned but not of record by such person or any affiliates or associates of such person, and the number of such shares of stock of the Corporation held by each such nominee holder, (iii) any material interest of each such person, or any affiliates or associates of each such person, in such business, (iv) a description of any transaction, agreement, arrangement or understanding with respect to such business between or among each such person and any of its affiliates or associates, and any others (including their names) in connection with the proposal of such business and any interest of such person or any affiliates or associates in such business, including the contemplated benefit therefrom to such person or affiliate or associate of such person, and a representation that the Proponent will notify the Corporation in writing of any such transaction, agreement, arrangement or understanding in effect as of the record date for the meeting not later than five business days following the later of the record date or the date notice of the record date is first publicly disclosed, (v) a description of any transaction, agreement, arrangement or understanding (including any derivative instruments, swaps, warrants, short positions, profit interests, options, hedging transactions, borrowed or loaned shares or other transactions) that has been entered into as of the date of the Proponent’s notice by, or on behalf of, each such person or any of its affiliates or associates, the effect or intent of which is to mitigate loss to, manage risk or benefit of share price changes for, or increase or decrease the voting power of each such person or any of its affiliates or associates with respect to shares of stock of the Corporation, and a representation that the Proponent will notify the Corporation in writing of any such transaction, agreement, arrangement or understanding in effect as of the record date for the meeting not later than five business days following the later of the record date or the date notice of the record date is first publicly disclosed, (vi) a representation that the Proponent is a holder of record or beneficial owner of shares of the Corporation entitled to vote at the annual meeting and intends to appear in person or by proxy at the meeting to propose such business, (vii) a representation whether the Proponent intends to deliver a proxy statement and/or form of proxy to holders of at least the percentage of the Corporation’s outstanding shares required to approve the proposal and/or otherwise to solicit proxies from stockholders in support of the proposal, and (viii) any other information relating to each such person that would be required to be disclosed in a proxy statement or other filing

6

required to be made in connection with the solicitation of proxies by each such person with respect to the proposed business to be brought by each such person before the annual meeting pursuant to Section 14 of the Exchange Act and the rules and regulations promulgated thereunder.

14. Compliance with Procedures. Notwithstanding anything in these By-laws to the contrary: (a) no business shall be conducted at any annual meeting except in accordance with the procedures set forth in paragraph 13 of this Article I, and (b) unless otherwise required by law, if a Proponent intending to propose business at an annual meeting pursuant to paragraph 13 of this Article I does not provide the information required under paragraph 13 to the Corporation (including providing the updated information required by clauses (b)(ii), (b)(iv) and (b)(v) of paragraph 13 by the deadlines specified therein), or the Proponent (or a qualified representative of the Proponent) does not appear at the meeting to present the proposed business, such business shall not be transacted, notwithstanding that proxies in respect of such business may have been received by the Corporation. The Chair of the meeting shall, if the facts warrant, determine and declare to the meeting that business was not properly brought before the meeting in accordance with the provisions of paragraph 13 of this Article I, and if he should so determine, he shall so declare to the meeting and any such business not properly brought before the meeting shall not be transacted. Nothing contained in paragraphs 13 and 14 of this Article I 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 under the Exchange Act (or any successor provision).

Article II

Directors.

1. Number; Election; Term. The number of directors which shall constitute the whole Board shall not be less than 5, nor more than 15, the exact number within said limits to be fixed from time to time solely by resolution of the Board, acting by the vote of not less than a majority of the directors then in office. The directors shall be divided into three classes, designated class I, class II and class III. Each class shall consist, as nearly as may be possible, of one-third of the total number of directors constituting the entire Board of Directors. The initial division of the Board of Directors into classes shall be made by the decision of the affirmative vote of a majority of the entire Board of Directors. The term of the initial class I directors shall terminate on the date of the 2014 annual meeting; the term of the initial class II directors shall terminate on the date of the 2015 annual meeting; and the term of the initial class III directors shall terminate on the date of the 2016 annual meeting or, in each case, upon such director’s earlier death, resignation or removal. At each succeeding annual meeting beginning in 2014, successors to the class of directors whose term expires at that annual meeting shall be elected for a three-year term and until their successors are duly elected and qualified. If the number of directors is changed, any increase or decrease shall be apportioned by the Board of Directors among the classes so as to maintain the number of directors in each class as nearly equal as possible, and any additional director of any class elected to fill a vacancy resulting from an increase in such class or from the removal from office, death, disability, resignation or disqualification of a director or other cause shall hold office for a term that shall coincide with the remaining term of that class, but in no case will a decrease in the number of directors have the effect of removing or shortening the term of any incumbent director.

7

2. Vacancies. Subject to the rights of the holders of any one or more series of Preferred Stock then outstanding, if the office of any director becomes vacant for any reason or any new directorship is created by any increase in the authorized number of directors, a majority of the directors then in office, although less than a quorum, may choose a successor or successors or fill the newly created directorship. Any director so chosen shall hold office until the next election of the class for which such director shall have been chosen and until his successor shall be elected and qualified.

3. Duties and Powers. The business and affairs of the Corporation shall be managed by or under the direction of the Board of Directors, which may exercise all such powers of the Corporation and do all such lawful acts and things as are not by statute or by the Certificate of Incorporation or by these By-laws required to be exercised or done by the stockholders.

4. Place of Meetings; Records. The directors may hold their meetings either within or without the State of Delaware and keep the books of the Corporation outside of the State of Delaware at such places as they may from time to time determine.

5. Organizational Meeting. As necessary, the Board of Directors shall meet for the purpose of organization, the election of officers and the transaction of other business, at its first meeting after or immediately prior to each annual meeting of stockholders. Such meeting may be held at any other time or place which shall be specified in a notice given as hereinafter provided for special meetings of the Board of Directors or in a consent and waiver of notice thereof signed by all of the directors.

6. Regular Meetings. Regular meetings of the Board may be held without notice at such time and place either within or without the State of Delaware as shall from time to time be determined by the Board.

7. Special Meetings. Special meetings of the Board may be called by the Chair of the Board, the President or Chief Executive Officer by the mailing of notice to each director at least 48 hours before the meeting or by notifying each director of the meeting at least 24 hours prior thereto either personally, by telephone or by electronic transmission; special meetings shall be called on like notice by the Chair of the Board, the President or Chief Executive Officer or, on the written request of any two directors, by the Secretary, or on such shorter notice as the person or persons calling such meeting may deem necessary or appropriate in the circumstances.

8. Organization. At each meeting of the Board of Directors or any committee thereof, the Chair of the Board of Directors or the chair of such committee, as the case may be, or, in his absence or if there be none, a director chosen by a majority of the directors present, shall act as chair. Except as provided below, the Secretary of the Corporation shall act as secretary at each meeting of the Board and of each committee thereof. In case the Secretary shall be absent from any meeting of the Board of Directors or of any committee thereof, an Assistant Secretary shall perform the duties of secretary at such meeting; and in the absence from any such meeting of the Secretary and all the Assistant Secretaries, the chair of the meeting may appoint any person to act as secretary of the meeting. Notwithstanding the foregoing, the members of each committee of the Board of Directors may appoint any person to act as secretary of any

8

meeting of such committee and the Secretary or any Assistant Secretary of the Corporation may, but need not if such committee so elects, serve in such capacity.

9. Quorum. At all meetings of the Board the presence of a majority of the total number of directors determined by resolution pursuant to paragraph 1 of this Article II to constitute the Board of Directors shall be necessary and sufficient to constitute a quorum for the transaction of business, and the act of a majority of the directors present at any meeting at which there is a quorum shall be the act of the Board of Directors, except as may be otherwise specifically provided by law, by the applicable rules of any securities exchange, by the Certificate of Incorporation or by these By-laws.

10. Committees. The Board of Directors may designate one or more committees, each committee to consist of one or more of the directors of the Corporation. Each member of a committee must meet the requirements for membership, if any, imposed by applicable law and the rules and regulations of any securities exchange or quotation system on which the securities of the Corporation are listed or quoted for trading. Any committee, to the extent permitted by law and provided in the resolution establishing such committee, 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 as the Board of Directors may by resolution duly delegate to it except as prohibited by law, and may authorize the seal of the Corporation to be affixed to all papers which may require it. Each committee shall keep regular minutes and report to the Board of Directors when required. Notwithstanding anything to the contrary contained in this Article II, the resolution of the Board of Directors establishing any committee of the Board of Directors and/or the charter of any such committee may establish requirements or procedures relating to the governance and/or operation of such committee that are different from, or in addition to, those set forth in these By-laws and, to the extent that there is any inconsistency between these By-laws and any such resolution or charter, the terms of such resolution or charter shall be controlling. Nothing herein shall limit the authority of the Board of Directors to appoint other committees consisting in whole or in part of persons who are not directors of the Corporation to carry out such functions as the Board may designate. Unless otherwise provided for in any resolution of the Board of Directors designating a committee pursuant to this paragraph 10 of Article II: (i) a quorum for the transaction of business of such committee shall be a majority of the authorized number of members of such committee; and (ii) the act of a majority of the members of such committee present at any meeting of such committee at which there is a quorum shall be the act of the committee (except as otherwise specifically provided by law, the Certificate of Incorporation or by these By-laws).

11. Presence at Meeting. Members of the Board of Directors or any committee designated by the Board may participate in the meeting of the Board or committee by means of conference telephone or similar communications equipment by means of which all persons in the meeting can hear each other and participate. The ability to participate in a meeting in the above manner shall constitute presence at said meeting for purposes of a quorum and any action thereat.

12. Action Without Meetings. Any action required or permitted to be taken at any meeting of the Board of Directors or any committee designated by the Board may be taken without a meeting, if all members of the Board or committee consent thereto in writing and the writing or writings are filed with the minutes of the proceedings of the Board or committee.

9

13. Compensation. The directors may be paid their expenses, if any, of attendance at each meeting of the Board of Directors and may be paid a fixed sum for attendance at each meeting of the Board of Directors or a stated salary for service as director, payable in cash and/or securities. 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 service as committee members.

14. Interested Directors. No contract or transaction between the Corporation and one or more of its directors or officers, or between the Corporation and any other corporation, partnership, association or other organization in which one or more of its directors or officers are directors or officers or have a financial interest, shall be void or voidable solely for this reason, or solely because the director or officer is present at or participates in the meeting of the Board of Directors or committee thereof which authorizes the contract or transaction, or solely because any such director’s or officer’s vote is counted for such purpose if: (i) the material facts as to the director’s or officer’s relationship or interest and as to the contract or transaction are disclosed or are known to the Board of Directors or the committee, and the Board of Directors or committee in good faith authorizes the contract or transaction by the affirmative votes of a majority of the disinterested directors, even though the disinterested directors constitute less than a quorum; or (ii) the material facts as to the director’s or officer’s relationship or interest and as to the contract or transaction are disclosed or are known to the stockholders entitled to vote thereon, and the contract or transaction is specifically approved in good faith by vote of the stockholders; or (iii) the contract or transaction is fair as to the Corporation as of the time it is authorized, approved or ratified by the Board of Directors, a committee thereof or the stockholders. Common or interested directors may be counted in determining the presence of a quorum at a meeting of the Board of Directors or of a committee which authorizes the contract or transaction.

15. Eligibility to Make Nominations. Nominations of candidates for election as directors at an annual meeting of stockholders or a special meeting of stockholders at which directors are to be elected pursuant to the Corporation’s notice of meeting (an “Election Meeting”) may be made (1) by any stockholder (a) who is a stockholder of record on the date of the giving of the notice provided for in paragraph 16 of this Article II and on the record date for the determination of stockholders entitled to notice of and to vote at such Election Meeting and (b) who complies with the notice procedures set forth in paragraph 16 of this Article II, or (2) by or at the direction of the Board of Directors (or any duly authorized committee thereof); provided, however, that nothing in these By-laws shall be deemed to limit any class voting rights upon the occurrence of dividend arrearages provided to holders of Preferred Stock. In order to be eligible for election as a director, any director nominee must first be nominated in accordance with the provisions of these By-laws.

16. Procedure for Nominations by Stockholders. Any stockholder (i) who is a stockholder of record on the date of the giving of the notice provided for in this paragraph 16 of this Article II and on the record date for the determination of stockholders entitled to notice of and to vote at such Election Meeting and (ii) who complies with the notice procedures set forth in this paragraph 16 of this Article II may nominate one or more persons for such election only if written notice of such stockholder’s intent to make such nomination is delivered to or mailed (including by courier) and received by the Secretary of the Corporation at the principal executive offices of the Corporation. In addition to any other applicable requirements, for a nomination to

The Corporation may require any proposed nominee to furnish such other information as it may reasonably require 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.

17. Compliance with Procedures. If the Chair of the Election Meeting determines that a nomination of any candidate for election as a director was not made in accordance with the applicable provisions of these By-laws, such nomination shall be void. Notwithstanding anything in these By-laws to the contrary, unless otherwise required by law, if a Proponent intending to make a nomination at an annual or special meeting pursuant to paragraph 16 of this Article II does not provide the information required under paragraph 16 to the Corporation (including providing the updated information required by clauses (b)(ii), (b)(iii) and (b)(iv) of paragraph 16 by the deadlines specified therein), or the Proponent (or a qualified representative of the Proponent) does not appear at the meeting to present the nomination, such nomination shall be disregarded, notwithstanding that proxies in respect of such nomination may have been received by the Corporation.

16

person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Corporation, and with respect to any criminal action or proceeding, had no reasonable cause to believe such person’s conduct was unlawful. The Corporation shall be required to indemnify a person in connection with a proceeding (or part thereof) initiated by such person only if the proceeding (or part thereof) was authorized by the Board of Directors of the Corporation.

2. Prepayment of Expenses. The Corporation shall pay the expenses (including attorneys’ fees) incurred by an officer or director of the Corporation in defending any proceeding in advance of its final disposition, except where the officer or director pleads guilty or nolo contendere in a criminal proceeding (excluding traffic violations and other minor offenses), provided, however, that the payment of such expenses shall be made only upon receipt of an undertaking by the director or officer to repay all amounts advanced if it shall ultimately be determined that the director or officer is not entitled to be indemnified. Payment of such expenses incurred by former officers or directors or other employees and agents of the Corporation may be made by the Board of Directors in its discretion upon such terms and conditions, if any, as it deems appropriate.

3. Claims. If a claim for indemnification or payment of expenses (including attorneys’ fees) under this Article is not paid in full within sixty days after a written claim therefor has been received by the Corporation the claimant may file suit to recover the unpaid amount of such claim and, if successful in whole or in part, shall be entitled to be paid the expense of prosecuting such claim.

4. Nonexclusivity of Rights. The right conferred on any person by this Article V shall not be exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under the Certificate of Incorporation, these By-laws, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in such person’s official capacity and as to action in another capacity while holding such office.

6. Certain Definitions. For purposes of this Article V, references to “the Corporation” shall include, in addition to the resulting corporation, any constituent corporation (including any constituent of a constituent) absorbed in a consolidation or merger which, if its separate existence had continued, would have had power and authority to indemnify its directors or officers, so that any person who is or was a director or officer of such constituent corporation, or is or was a director or officer of such constituent corporation serving at the request of such

17

constituent corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, shall stand in the same position under the provisions of this Article V with respect to the resulting or surviving corporation as such person would have with respect to such constituent corporation if its separate existence had continued. For purposes of this Article V, references to “fines” shall include any excise taxes assessed on a person with respect to an employee benefit plan; and references to “serving at the request of the Corporation” shall include any service as a director, officer, employee or agent of the Corporation which imposes duties on, or involves services by, such director or officer with respect to an employee benefit plan, its participants or beneficiaries; and a person who acted in good faith and in a manner such person reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner “not opposed to the best interests of the Corporation” as referred to in this Article V.

7. Survival of Indemnification and Advancement of Expenses. The indemnification and, subject to the discretion of the Board of Directors, advancement of expenses provided by, or granted pursuant to, this Article V shall, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to be a director or officer and shall inure to the benefit of the heirs, executors and administrators of such a person.

8. Other Indemnification. The Corporation’s obligation, if any, to indemnify any person who was or is serving at its request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, enterprise or non profit entity shall be reduced by any amount such person may collect as indemnification from such other corporation, partnership, joint venture, trust, non profit entity, or other enterprise.

9. Amendment or Repeal. Any repeal or modification of the foregoing provisions of this Article V shall not adversely affect any right or protection hereunder of any person in respect of any act or omission occurring prior to the time of such repeal or modification.

10. Indemnification of Employees and Agents. The Corporation may, to the extent authorized from time to time by the Board of Directors, provide rights to indemnification and to the advancement of expenses to employees and agents of the Corporation similar to those conferred in this Article V to directors and officers of the Corporation.

4. Notice. Whenever notice is required to be given by law, the Certificate of Incorporation or these By-laws, a written waiver signed by the person entitled to notice, whether before or after the time stated therein, shall be deemed equivalent to 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. Without limiting the manner by which notice otherwise may be given effectively to stockholders, any notice to stockholders given by the Corporation under applicable law, the Certificate of Incorporation or these By-laws shall be effective if given by a form of electronic transmission if consented to by the stockholder to whom the notice is given. Any such consent shall be revocable by the stockholder by written notice to the Corporation. Any such consent shall be deemed to be revoked if (i) the Corporation is unable to deliver by electronic transmission two (2) consecutive notices by the Corporation in accordance with such consent and (ii) such inability becomes known to the Secretary or Assistant Secretary of the Corporation or to the transfer agent, or other person responsible for the giving of notice; provided, however, that the inadvertent failure to treat such inability as a revocation shall not invalidate any meeting or other action. Notice given by electronic transmission, as described above, shall be deemed given: (i) if by facsimile telecommunication, when directed to a number at which the stockholder has consented to receive notice; (ii) if by electronic mail, when directed to an electronic mail address at which the stockholder has consented to receive notice; (iii) if by a posting on an electronic network, together with separate notice to the stockholder of such specific posting, upon the later of (A) such posting and (B) the giving of such separate notice; and (iv) if by any other form of electronic transmission, when directed to the stockholder.

19

legible form within a reasonable time. The Corporation shall so convert any records so kept upon the request of any person entitled to inspect the same.

7. Checks. All checks, drafts, notes and other orders for the payment of money shall be signed by such officer or officers or agents as from time to time may be designated by the Board of Directors or by such officers of the Corporation as may be designated by the Board to make such designation.
