(c) Without limiting the manner by which notice otherwise may be given effectively to stockholders (including, without limitation, electronic notices permitted by Sections 204(g) and 242(b)(1) of the Delaware General Corporation Law) any notice to stockholders given by the Corporation under any provision of Delaware General Corporation Law, the Certificate of Incorporation, or these Bylaws shall be effective if given by a form of electronic transmission 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 revoked if (i) the Corporation is unable to deliver by electronic transmission two consecutive notices given by the Corporation in accordance with such consent, and (ii) such inability becomes known to the Secretary or an Assistant Secretary of the Corporation or to the transfer agent or other person responsible for the giving of notice; provided, however, the inadvertent failure to treat such inability as a revocation shall not invalidate any meeting or other action. An affidavit of the Secretary or an Assistant Secretary or of the transfer agent or other agent of the Corporation that the notice has been given by a form of electronic transmission shall, in the absence of fraud, be prima facie evidence of the facts stated therein. Notice given pursuant to this subparagraph (c) shall be deemed given: (1) if by facsimile telecommunication, when directed to a number at which the stockholder has consented to receive notice; (2) if by electronic mail, when directed to an electronic mail address at which the stockholder has consented to receive notice; (3) 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 (4) if by any other form of electronic transmission, when directed to the

2

stockholder. For purposes of these Bylaws, “electronic transmission” means any form of communication, not directly involving the physical transmission of paper, that creates a record that may be retained, retrieved and reviewed by a recipient thereof, and that may be directly reproduced in paper form by such a recipient through an automated process.

Section 2.5. Quorum and Voting.

(a) At any meeting of the stockholders, except where otherwise provided by law, the Certificate of Incorporation or these Bylaws, the presence, in person or by proxy, of the holders of a majority of the outstanding shares of stock entitled to vote at any meeting shall constitute a quorum for the transaction of business. Shares of stock, the voting of which at said meeting have been enjoined, or which for any reason cannot be lawfully voted at such meeting, shall not be counted to determine a quorum at said meeting. Any regular or special meeting of the stockholders, whether or not a quorum is present, may be adjourned from day to day or from time to time by the chairman of the meeting or by the vote of the holders of a majority of the shares entitled to vote at said meeting, but no other business shall be transacted at such adjourned meeting. Such adjournment and the reasons therefor shall be recorded in the minutes of the proceedings. The stockholders present at a duly called or convened meeting at which a quorum is present may continue to transact business until adjournment, notwithstanding the withdrawal of enough stockholders to leave less than a quorum.

(b) Except as otherwise provided by law, the Certificate of Incorporation or these Bylaws, all action taken by the holders of a majority of the votes cast on a matter affirmatively or negatively shall be valid and binding upon the Corporation. For purposes of these Bylaws, a share present at a meeting, but for which there is an abstention or as to which a stockholder gives no authority or direction as to a particular proposal or director nominee, shall be counted as present for the purpose of establishing a quorum but shall not be counted as a vote cast, except to the extent permitted by applicable law or the principal securities exchange on which the Corporation’s securities are listed.

Section 2.6. Waiver of Notice.

When all the stockholders of the Corporation are present, in person or by proxy, at any meeting, or when the stockholders not present, in person or by proxy, thereat give their written consent, either before or after such meeting, to the holding thereof at the time and place the meeting is held, and such written consent is made a part of the records of such meeting, the proceedings had at such meeting are valid, irrespective of the manner in which the meeting is called or the place where it is held.

Section 2.7. Voting Rights.

(a) Except as otherwise provided by law, only persons in whose names shares entitled to vote stand on the stock records of the Corporation on the record date for determining the stockholders entitled to vote at said meeting shall be entitled to vote at such meeting. Shares standing in the names of two or more persons shall be voted or represented in accordance with the determination of the majority of such persons, or, if only one of such persons is present in person or represented by proxy, such person shall have the right to vote such shares and such shares shall be deemed to be represented for the purpose of determining a quorum.

(b) Every person entitled to vote or to execute consents shall have the right to do so either in person or by an agent or agents authorized by a written proxy executed by such person or such person’s duly authorized agent, which proxy shall be filed with the Secretary of the Corporation at or before the meeting at which it is to be used. Said proxy so appointed need not be a stockholder. No proxy shall be voted on after the expiration of eleven (11) months from the date of its execution, unless the person executing it specifies therein the length of time for which such proxy is to continue in force, which in no case shall exceed seven (7) years from the date of its execution. Unless and until voted, every proxy shall be revocable at the pleasure of the person who executed it or of such person’s legal representatives or assigns, except in those cases where an irrevocable proxy permitted by statute has been given.

(c) Without limiting the manner in which a stockholder may authorize another person or persons to act for such stockholder as proxy pursuant to Section 2.7(b), the following shall constitute a valid means by which a stockholder may grant such authority:

3

(1) A stockholder may execute a writing authorizing another person or persons to act for such stockholder as proxy. Execution may be accomplished by the stockholder or such stockholder’s authorized officer, director, employee or agent signing such writing or causing his or her signature to be affixed to such writing by any reasonable means including, but not limited to, by facsimile signature or by other means of electronic transmission.

(2) A stockholder may authorize another person or persons to act for such stockholder 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 any such transmission must either set forth or be submitted with information from which it can be determined that the transmission was authorized by the stockholder. Such authorization can be established by the signature of the stockholder on the proxy, either in writing or by a signature stamp, facsimile signature, other means of electronic transmission, or by a number or symbol from which the identity of the stockholder can be determined, or by any other procedure deemed appropriate by the inspectors or other persons making the determination as to due authorization.

If it is determined that such transmissions are valid, the inspectors or, if there are no inspectors, such other persons making that determination shall specify the information upon which they relied.

(d) Any copy, facsimile telecommunication or other reliable reproduction of the writing or transmission created pursuant to Section 2.7(c) may be substituted or used in lieu of the original writing or transmission for any and all purposes for which the original writing or transmission could be used, provided that such copy, facsimile telecommunication or other reproduction shall be a complete reproduction of the entire original writing or transmission.

Section 2.8. Voting Procedures and Inspectors of Elections.

(a) The Corporation shall, in advance of any meeting of stockholders, appoint one or more inspectors 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. If no inspector or alternate is able to act at a meeting of stockholders, the person presiding at the meeting shall appoint one or more inspectors to act at the meeting. Each inspector, before entering upon the discharge of his or her duties, shall take and sign an oath faithfully to execute the duties of inspector with strict impartiality and according to the best of his or her ability.

(b) The inspectors shall (i) ascertain the number of shares outstanding and the voting power of each, (ii) determine the shares represented at a 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 represented at the meeting and their count of all votes and ballots. The inspectors may appoint or retain other persons or entities to assist the inspectors in the performance of the duties of the inspectors.

(c) 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 the meeting. No ballot, proxies or votes, nor any revocations thereof or changes thereto, shall be accepted by the inspectors after the closing of the polls unless the Court of Chancery shall determine otherwise upon application by a stockholder.

(d) In determining the validity and counting of proxies and ballots, the inspectors shall be limited to an examination of the proxies, any envelopes submitted with those proxies, any information provided in accordance with Sections 211(e) or 212(c) of the Delaware General Corporation Law, or any information provided pursuant to Sections 211(a)(2)(B)(i) or (iii) thereof, ballots and the regular books and records of the Corporation, except that the inspectors may consider other reliable information for the limited purpose of reconciling proxies and ballots submitted by or on behalf of banks, brokers, their nominees or similar persons which represent more votes than the holder of a proxy is authorized by the record owner to cast or more votes than the stockholder holds of record. If the inspectors consider other reliable information for the limited purpose permitted herein, the inspectors at the time they make their certification pursuant to Section 2.8(b)(v) shall specify the precise information considered by them including the person or persons from whom they obtained the information, when the information was obtained, the means by which the information was obtained and the basis for the inspectors’ belief that such information is accurate and reliable.

Section 2.9. List of Stockholders.

The officer who has charge of the stock ledger of the Corporation shall prepare and make, at least ten (10) days before every meeting of stockholders, a complete list of the stockholders entitled to vote at said meeting, (or, if the record date for determining the stockholders entitled to vote is less than ten (10) days before the meeting date, the list shall reflect the stockholders entitled to vote on the tenth (10^th) day before the meeting date), arranged in alphabetical order, showing the address of and the number of shares registered in the name of each stockholder. The Corporation need not include electronic mail addresses or other electronic contact information on such list. Such list shall be open to the examination of any stockholder for any purpose germane to the meeting for a period of at least ten (10) days prior to the meeting: (i) on a reasonably accessible electronic network, provided that the information required to gain access to such list is provided with the notice of the meeting, or (ii) during ordinary business hours at the principal place of business of the Corporation. In the event that the Corporation determines to make the list available on an electronic network, the Corporation may take reasonable steps to ensure that such information is available only to stockholders of the Corporation. If the meeting is to be held at a place, then the list shall be produced and kept at the time and place of the meeting during the whole time thereof, and may be inspected by any stockholder who is present. If the meeting is to be held solely by means of remote communication, then the list shall also be open to the examination of any stockholder during the whole time of the meeting on a reasonably accessible electronic network, and the information required to access such list shall be provided with the notice of the meeting.

Section 2.10. Proper Business for Stockholder Meetings

(a) At a meeting of the stockholders, only such business shall be conducted as shall have been properly brought before the meeting. To be properly brought before a meeting, business must be (1) specified in the notice of meeting (or any supplement thereto) given by or at the direction of the Board of Directors, (2) otherwise properly brought before the meeting by or at the direction of the Board of Directors or the Chairman of the Board of Directors, or (3) otherwise properly brought before the meeting by a stockholder of the Corporation who is a stockholder of record at the time of giving the notice provided for herein, who shall be entitled to vote at such meeting and who complies with the notice procedures set forth herein.

(b) In addition to any other applicable requirements for business to be properly brought before a meeting by a stockholder, whether or not the stockholder is seeking to have a proposal included in the Corporation’s proxy statement or information statement under Rule 14a-8 under the Exchange Act, the stockholder must have given timely notice thereof in writing to the Secretary of the Corporation. To be timely as to an annual meeting of stockholders (or in the case of a stockholder seeking to have a proposal included in the Corporation’s proxy statement or information statement), a stockholder’s notice must be delivered to the Secretary at the principal executive office of the Corporation not less than one hundred and twenty (120) calendar days prior to the first anniversary of the date on which the Corporation first mailed, or made available, as applicable, its proxy materials (or, in the absence of proxy materials, its notice of meetings) for the previous year’s annual meeting. However, if the Corporation did not hold an annual meeting the previous year, or if the date of the annual meeting is advanced more than thirty (30) days prior to or delayed by more than thirty (30) days after the anniversary of the preceding year’s annual meeting, then to be timely, notice by the stockholder must be delivered to the Secretary at the Corporation’s principal executive offices not later than the close of business on the tenth (10^th) day following the earlier of the day on which notice of the date of the meeting was mailed to stockholders or public disclosure of such date was made. To be timely as to a special meeting of stockholders, a stockholder notice must be received not later than the call of the meeting as provided for in this Article II. In no event shall any adjournment or postponement of a meeting or the announcement thereof commence a new time period for the giving of a stockholder’s notice as described above. Other than with respect to stockholder proposals relating to director nomination(s), which requirements are set forth in Section 2.10 below and Section 3.3, a stockholder’s notice to the Secretary (whether for an annual meeting or a special meeting) shall set forth as to each matter the stockholder proposes to bring before the meeting: (1) a brief description of the business desired to be brought before the meeting and the reasons for conducting such business at the meeting; (2) the name and address, as they appear on the Corporation’s books, and the name and address of the beneficial owner, if any, on whose behalf the proposal is made; (3) the class and number of shares of the Corporation which are owned beneficially and of record by such stockholder of record and by the beneficial owner, if any, on whose behalf the proposal is made; (4) any material interest of such stockholder of record and the beneficial owner, if any, on whose behalf the proposal is made, in such proposal, (5) as to the stockholder giving the notice and any Stockholder Associated Person (as defined below) or any member of such stockholder’s immediate family sharing the same household, whether and the extent to which any

5

hedging or other transaction or series of transactions has been entered into by or on behalf of, or any other agreement, arrangement, or understanding (including, but not limited to, any short position or any borrowing or lending of shares of stock) has been made, the effect or intent of which is to mitigate loss or increase profit to or manage the risk or benefit of stock price changes for, or to increase or decrease the voting power of, such stockholder, such Stockholder Associated Person, or family member with respect to any share of stock of the Corporation (each, a “Relevant Hedge Transaction”), and (6) as to the stockholder giving the notice and any Stockholder Associated Person or any member of such stockholder’s immediate family sharing the same household, to the extent not set forth pursuant to the immediately preceding clause, (i) whether and the extent to which such stockholder, Stockholder Associated Person, or family member has direct or indirect beneficial ownership of any option, warrant, convertible security, stock appreciation right, or similar right with 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, 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 any other 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 (a “Derivative Instrument”), (ii) any rights to dividends on the shares of the Corporation owned beneficially by such stockholder, Stockholder Associated Person, or family member that are separated or separable from the underlying shares of the Corporation, (iii) any proportionate interest in shares of the Corporation or Derivative Instruments held, directly or indirectly, by a general or limited partnership in which such stockholder, Stockholder Associated Person, or family member is a general partner or, directly or indirectly, beneficially owns an interest in a general partner, and (iv) any performance-related fees (other than an asset-based fee) that such stockholder, Stockholder Associated Person, or family member is entitled to, based on any increase or decrease in the value of shares of the Corporation or Derivative Instruments, if any, as of the date of such notice (which information shall be supplemented by such stockholder and beneficial owner, if any, not later than ten (10) days after the record date for the meeting to disclose such ownership as of the record date). With respect to stockholder proposals relating to director nominations pursuant to Section 3.3, in addition to the information above, the stockholder’s notice shall set forth as to each person whom the stockholder proposes to nominate for election or re-election as a director, (i) the name, age, business address, and residence address of the person, (ii) the principal occupation or employment of the person, (iii) the class and number of shares of the Corporation which are beneficially owned by the person, (iv) a statement whether such person, if elected, intends to tender a resignation effective upon such person’s failure to receive the required vote for re-election at the next meeting at which such person would face re-election and upon acceptance of such resignation by the Board of Directors, in accordance with the Corporation’s Corporate Governance Guidelines, and (v) any other information relating to the person that is required to be disclosed in solicitations for proxies for election of directors, or is otherwise required, in each case pursuant to Regulation 14A under the Exchange Act (including such person’s written consent to being named in the proxy statement as a nominee and to serving as a director if elected).

For purposes of this Section 2.10, “Stockholder Associated Person” of any stockholder shall mean (i) any person controlling or controlled by, directly or indirectly, or acting in concert with, such stockholder, (ii) any beneficial owner of shares of stock of the Corporation owned of record or beneficially by such stockholder and (iii) any person controlling, controlled by or under common control with such Stockholder Associated Person.

Notwithstanding anything in the Bylaws to the contrary, no business shall be conducted at a meeting except in accordance with the procedures set forth in Section 2.1 and this Section 2.10, provided, however, that nothing in this Section 2.10 shall be deemed to preclude discussion by any stockholder of any business properly brought before a meeting in accordance with said procedure. Further, a shareholder shall also comply with all applicable requirements of the Exchange Act and the rules and regulations thereunder with respect to the matters set forth herein.

The Chairman of the Board of Directors or the individual designated as chairman 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 Section 2.1 and this Section 2.10, and if he or she should so determine, he or she shall so declare to the meeting, and any such business not properly brought before the meeting shall not be transacted.

Nothing in this Section 2.10 shall affect the right of a stockholder to request inclusion of a proposal in the Corporation’s proxy statement or information statement pursuant to, and in accordance with, Rule 14a-8 under the Exchange Act.

Section 2.11. Action Without Meeting.

(a) Unless otherwise provided in the Certificate of Incorporation, any action required by statute to be taken at any annual or special meeting of stockholders of the Corporation, or any action which may be taken at any annual or special meeting of such stockholders, may be taken without a meeting, without prior notice and without a vote, if a consent or consents in writing setting forth the action so taken are signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted. To be effective, a written consent must be delivered to the Corporation by delivery to its registered office in Delaware, its principal place of business, or an officer or agent of the Corporation having custody of the book in which proceedings of meetings of stockholders are recorded. Delivery made to a 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 of the earliest dated consent delivered in the manner required by this Section 2.11 to the Corporation, written consents signed by a sufficient number of holders to take action are delivered to the Corporation in accordance with this Section 2.11. 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.

(b) An electronic transmission consent to an action to be taken and transmitted by a stockholder or proxyholder, or by a person or persons authorized to act for a stockholder or proxyholder, shall be deemed to be written, signed and dated for the purposes of this Section 2.11, provided that any such electronic transmission sets forth or is delivered with information from which the Corporation can determine (1) that the electronic transmission was transmitted by the stockholder or proxyholder or by a person or persons authorized to act for the stockholder or proxyholder, and (2) the date on which such stockholder or proxyholder or authorized person or persons transmitted such electronic transmission. The date on which such electronic transmission is transmitted shall be deemed to be the date on which such consent was signed. No consent given by electronic transmission shall be deemed to have been delivered until such consent is reproduced in paper form and until such paper form shall be delivered to the Corporation by delivery to its registered office in the State of Delaware, its principal place of business or an officer or agent of the Corporation having custody of the book in which proceedings of meetings of stockholders are recorded. Delivery made to a Corporation’s registered office shall be made by hand or by certified or registered mail, return receipt requested. Notwithstanding the foregoing limitations on delivery, consents given by electronic transmission may be otherwise delivered to the principal place of business of the Corporation or to an officer or agent of the Corporation having custody of the book in which proceedings of meetings of stockholders are recorded if to the extent and in the manner provided by resolution of the Board of Directors of the Corporation.

(c) 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.

ARTICLE III

BOARD OF DIRECTORS

Section 3.1. Number – Quorum.

(a) The business of the Corporation shall be managed by a Board of Directors, whose number shall be not fewer than nine (9) nor greater than thirteen (13), as the Board of Directors by resolution or the stockholders by amendment of these Bylaws may establish; provided, however, that a reduction in the authorized number of directors shall not remove any director prior to the expiration of such director’s term of office.

(b) A quorum of the Board of Directors shall consist of a majority of the exact number of directors fixed from time to time in accordance with Section 3.1, but not less than one; provided, however, at any meeting, whether a quorum be present or otherwise, a majority of the directors present may adjourn from time to time until the time fixed for the next regular meeting of the Board of Directors, without notice other than by announcement at the meeting. At a meeting at which a quorum is present, unless a different vote be required by law, the Certificate of Incorporation, or these Bylaws, every decision or act of a majority of the directors present made or done when duly assembled shall be valid as the act of the Board of Directors, provided that a minority of the directors, in the absence of a quorum, may adjourn from day to day but may transact no business.

7

(c) With the exception of the first Board of Directors, which shall be elected by the incorporators, and except as provided in Section 3.6, the directors shall be elected by a plurality vote of the votes cast and entitled to vote on the election of directors at any meeting for the election of directors at which a quorum is present.

Section 3.2. Exact Number of Directors.

The exact number of Directors of the Corporation shall be fixed from time to time, within the limits specified in this Article III, by resolution of the Board of Directors or otherwise pursuant to the provisions of Section 3.1.

Section 3.3. Director Nominating Procedure.

(a) In addition to any other applicable requirements, only persons who are nominated in accordance with the following procedures shall be eligible for election as directors. Nominations of persons for election to the Board of Directors of the Corporation may be made at a meeting of stockholders (i) pursuant to the Corporation’s notice of meeting (or any supplement thereto) given by or at the direction of the Board of Directors, (ii) by or at the direction of the Board of Directors, or by any nominating committee or person appointed by the Board of Directors or (iii) by any stockholder of the Corporation who is a stockholder of record at the time of giving of notice provided for in this Section 3.3, who is entitled to vote for the election of directors at the meeting and who complies with the notice procedures set forth in this Section 3.3. The foregoing clause (iii) shall be the exclusive means for a stockholder to make nominations at a meeting of stockholders. A stockholder who complies with the notice procedures set forth in this Section 3.3 is permitted to present the nomination at the meeting of stockholders but is not entitled to have a nominee included in the Corporation’s proxy statement in the absence of an applicable rule of the U.S. Securities and Exchange Commission requiring the Corporation to include a director nomination made by a stockholder in the Corporation’s proxy statement or information statement.

Nominations by stockholders shall be made pursuant to timely notice in writing to the Secretary of the Corporation. To be timely as to an annual meeting, notice by the stockholder must be delivered to the Secretary at the Corporation’s principal executive offices not later than one hundred and twenty (120) calendar days prior to the first anniversary of the date on which the Corporation first mailed, or made available, as applicable, its proxy materials (or, in the absence of proxy materials, its notice of meetings) for the previous year’s annual meeting. However, if the Corporation did not hold an annual meeting the previous year, or if the date of the annual meeting is advanced more than thirty (30) days prior to or delayed by more than thirty (30) days after the anniversary of the preceding year’s annual meeting, then to be timely, notice by the stockholder must be delivered to the Secretary at the Corporation’s principal executive offices not later than the close of business on the tenth (10^th) day following the earlier of the day on which notice of the date of the meeting was mailed to stockholders or public disclosure of such date was made. To be timely as to a special meeting of stockholders at which directors are to be elected, a stockholder notice must be received not later than the close of business on the tenth (10^th) day following the earlier of the day on which notice of the date of the meeting was mailed to stockholders or public disclosure of such date was made. In no event shall any adjournment or postponement of a meeting or the announcement thereof commence a new time period for the giving of a stockholder’s notice as described above. The stockholder’s notice relating to director nomination(s) shall set forth (a) as to each person whom the stockholder proposes to nominate for election or re-election as a director, the information required by Section 2.10(b); (b) as to the stockholder giving the notice, (i) the name and address, as they appear on the Corporation’s books, of such stockholder and (ii) the class and number of shares of the Corporation which are beneficially owned by such stockholder and also which are owned of record by such stockholder; and (c) as to the beneficial owner, if any, on whose behalf the nomination is made, (i) the name and address of such person and (ii) the class and number of shares of the Corporation which are beneficially owned by such person. At the request of the Board, any person nominated by the Board for election as a director shall furnish to the Secretary that information required to be set forth in the stockholder’s notice of nomination which pertains to the nominee. The Corporation may require any proposed nominee to furnish such other information as may reasonably be required by the Corporation to determine the eligibility and/or qualifications of such proposed nominee to serve as a director of the Corporation. The stockholder giving such notice shall indemnify the Corporation in respect of any loss arising as a result of any false or misleading information or statement submitted by the nominating stockholder in connection with the nomination, as provided by Section 112(5) of the Delaware General Corporation Law. No person shall be eligible for election as a director of the Corporation unless nominated in accordance with the procedures set forth herein. These provisions shall not apply to nomination of any persons entitled to be separately elected by holders of preferred stock.

8

(b) Except for the filling of vacancies, as provided for in the Certificate of Incorporation and Section 3.6, no person shall be qualified to serve as a director of the Corporation unless nominated in accordance with the procedures set forth in this Bylaw. The Chairman of the Board of Directors or the individual designated as chairman of the meeting shall, if the facts warrant, determine, and declare to the meeting that a nomination was not made in accordance with the procedures prescribed by these Bylaws, and if the chairman should so determine, that the defective nomination shall be disregarded. Notwithstanding the foregoing provisions of this Bylaw, a stockholder shall also comply with all applicable requirements of the Exchange Act and the rules and regulations thereunder with respect to the matters set forth in this Bylaw.

Section 3.4. Qualification of Directors

The majority of directors of the Board of Directors shall not be officers or employees of the Corporation or any of its subsidiaries and shall not have held such positions at any time during the three years prior to election or selection to the Board of Directors. Whether an individual, who is an officer or employee of the Corporation or any of its subsidiaries, satisfies this qualification requirement will be determined at the time of his or her election or selection.

Section 3.5. Election and Term of Office.

The directors shall be elected at each annual meeting of stockholders, but if, for any cause, any such annual meeting is not held, or the directors are not elected thereat, the directors may be elected as soon as convenient at any special meeting of stockholders held for that purpose in the manner provided in these Bylaws. All directors shall hold office until the next annual meeting of stockholders and until their respective successors are elected and qualified. In no case will a decrease in the number of directors shorten the term of any incumbent director.

Section 3.6. Vacancies; Resignations and Removals.

(a) As provided in the Certificate of Incorporation, except as otherwise required by law and subject to the rights of the holders of any series of stock with respect to such series of stock, unless the Board of Directors otherwise determines, vacancies on the Board of Directors from newly created directorships resulting from any increase in the authorized number of directors or any vacancies on the Board of Directors resulting from the death, resignation, retirement, disqualification, removal from office or other cause shall be filled only by a majority vote of the directors then in office, though less than a quorum, or by a sole remaining director, and not by the stockholders. Each director so elected shall hold office until the unexpired portion of the term of the director whose place shall be vacant and until such director’s successor shall have been duly elected and qualified following the election at the next annual meeting of the stockholders or at any special meeting of stockholders duly called for that purpose prior to such annual meeting.

(b) Any director may resign at any time by delivering a written resignation to the Secretary or by electronic transmission, such resignation to specify whether it will be effective at a particular time, upon receipt by the Secretary or at the pleasure of the Board of Directors. If no such specification is made it shall be deemed effective at the pleasure of the Board of Directors. When one or more of the directors shall resign from the Board of Directors, effective at a future date, a majority of the directors then in office, including those who have so resigned, shall have the power to fill such vacancy or vacancies, the vote thereon to take effect when such resignation or resignations shall become effective. Each director so appointed shall hold office during the unexpired portion of the term of office of the resigning director or directors whose place shall be vacated and until their successors shall have been duly elected and qualified.

Section 3.7. Annual and Regular Meetings.

ARTICLE VIII

INDEMNIFICATION

Section 8.1. Right to Indemnification.

Each person who was or is a party or is threatened to be made a party to or is involved (as a party, witness, or otherwise), in any threatened, pending, or completed action, suit, or proceeding, formal or informal, whether brought in the name of the Corporation or otherwise and whether of a civil, criminal, administrative, or investigative (hereinafter a “Proceeding”), by reason of the fact that he or she, or a person of whom he or she is the legal representative, is or was a director, officer, employee, or agent of the Corporation or is or was serving at the request of the Corporation as a director, officer, employee, or agent of another Corporation or of a partnership, joint venture, trust, or other enterprise, including service with respect to employee benefit plans, whether the basis of the Proceeding is alleged action or inaction in an official capacity as a director, officer, employee, or agent or in any other capacity while serving as a director, officer, employee, or agent (all such individuals being collectively referred to as an “Agent”), shall, subject to the terms of any agreement between the Corporation and such person, be indemnified and held harmless by the Corporation to the fullest extent authorized by the Delaware General Corporation Law, as the same exists or may hereafter be amended or interpreted (but, in the case of any such amendment or interpretation, only to the extent that such amendment or interpretation permits the Corporation to provide broader indemnification rights than were permitted prior thereto), against all charges, costs, expenses, liabilities, and losses (including attorneys’ fees, judgments, fines, ERISA excise taxes or penalties, and amounts paid or to be paid in settlement, and any interest, assessments, or other charges imposed thereon, and any federal, state, local, or foreign taxes imposed on any Agent as a result of the actual or deemed receipt of any payments under this Article VIII) reasonably incurred or suffered by such person in connection with investigating, defending, being a witness in, or participating in (including on appeal), or preparing for any of the foregoing in, any Proceeding (hereinafter “Expenses”) and the such indemnification shall continue as to a person who has ceased to be an Agent and shall inure to the benefit of the heirs, executors, and administrators of such a person; provided, however, that the Corporation shall indemnify any Agent seeking indemnification 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.

Section 8.2. Authority to Advance Expenses.

Expenses incurred by an officer or director (acting in his or her capacity as such) in defending a Proceeding shall be paid by the Corporation in advance of the final disposition of such Proceeding, provided, however, that if required by the Delaware General Corporation Law, as amended, such Expenses shall be advanced only upon delivery to the Corporation of an undertaking by or on behalf of such director or officer to repay such amount if it shall ultimately be determined that he or she is not entitled to be indemnified by the Corporation as authorized in this Article VIII or otherwise. Expenses incurred by other Agents of the Corporation (or by the directors or officers not acting in their capacity as such, including service with respect to employee benefit plans) may be advanced upon such terms and conditions as the Board of Directors deems appropriate. Any obligation to reimburse the Corporation for Expense advances shall be unsecured and no interest shall be charged thereon.

12

Section 8.3. Right of Claimant to Bring Suit.

If a claim under Section 8.1 or 8.2 is not paid in full by the Corporation within thirty (30) days after a written claim has been received by the Corporation, the claimant may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim and, if successful in whole or in part, the claimant shall be entitled to be paid also the expense (including attorneys’ fees) of prosecuting such claim. It shall be a defense to any such action (other than an action brought to enforce a claim for expenses incurred in defending a Proceeding in advance of its final disposition where the required undertaking has been tendered to the Corporation) that the claimant has not met the standards of conduct that make it permissible under the Delaware General Corporation Law for the Corporation to indemnify the claimant for the amount claimed. The burden of proving such a defense shall be on the Corporation. Neither the failure of the Corporation (including its Board of Directors, independent legal counsel, or its stockholders) to have made a determination prior to the commencement of such action that indemnification of the claimant is proper under the circumstances because he or she has met the applicable standard of conduct set forth in the Delaware General Corporation Law, nor an actual determination by the Corporation (including its Board of Directors, independent legal counsel, or its stockholders) that the claimant had not met such applicable standard of conduct, shall be a defense to the action or create a presumption that claimant has not met the applicable standard of conduct.

Section 8.4. Successful Defense.

Notwithstanding any other provision of this Article, to the extent that a director or officer has been successful on the merits or otherwise (including the dismissal of an action without prejudice or the settlement of a proceeding or action without admission of liability) in defense of any proceeding referred to in Section 8.1 or in defense of any claim, issue or matter therein, he or she shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred in connection therewith.

Section 8.5. Non-Exclusivity of Rights.

The rights conferred on any person by this Article VIII shall not be exclusive of any other rights that such person may have or hereafter acquire under any statute, provision of the Certificate of Incorporation, agreement, vote of stockholders or disinterested directors, or otherwise, both as to action in an official capacity and as to action in another capacity while holding such office. To the extent that any provision of the Certificate of Incorporation, agreement, or vote of the stockholders or disinterested directors is inconsistent with these Bylaws, the provision, agreement, or vote shall take precedence.

Section 8.6. Insurance.

The Corporation may purchase and maintain insurance, at its expense, to protect itself and any Agent or another Corporation, partnership, joint venture, trust or other enterprise against any Expense, whether or not the Corporation would have the power to indemnify such person or entity against such Expense under applicable law or the provisions of this Article VIII.

Section 8.7. Expenses as a Witness.

To the extent that any Agent of the Corporation is by reason of such position, or a position with another entity at the request of the Corporation, a witness in any action, suit, or proceeding, he or she shall be indemnified against all costs and expenses actually and reasonably incurred by him or her on his or her behalf in connection therewith.

Section 8.8. Indemnity Agreements.

The Corporation may enter into agreements with any Agent of the Corporation providing for indemnification to the fullest extent permissible under the Delaware General Corporation Law and the Corporation’s Certificate of Incorporation.

13

Section 8.9. Enforcement of Rights.

Without the necessity of entering into an express contract, all rights provided under this Article VIII shall be deemed to be contractual rights and be effective to the same extent and as if provided for in a contract between the Corporation and such Agent. Any rights granted by this Article VIII to an Agent shall be enforceable by or on behalf of the person holding such right in any court of competent jurisdiction.

Section 8.10. Effect of Amendment.

Any amendment, repeal, or modification of this Article VIII that adversely affects any rights provided in this Article VIII to an Agent shall only be effective upon the prior written consent of such Agent.

Section 8.11. Subrogation.

In the event of payment under this Article VIII, the Corporation shall be subrogated to the extent of such payment to all of the rights of recovery of the Agent, who shall execute all papers required and shall do everything that may be necessary to secure such rights, including the execution of such documents necessary to enable the Corporation effectively to bring suit to enforce such rights.

Section 8.12. No Duplication of Payments.

The Corporation shall not be liable under this Article to make any payment in connection with any claim made against the Agent to the extent the Agent has otherwise actually received payment (under any insurance policy, agreement, vote, or otherwise) of the amounts otherwise indemnifiable hereunder.

Section 8.13. Saving Clause.

If this Article VIII or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the Corporation shall nevertheless indemnify each Agent to the fullest extent not prohibited by any applicable portion of this Article VIII that shall not have been invalidated, or by any other applicable law.

ARTICLE IX

Delivery made to a Corporation’s registered office shall be by hand or by certified or registered mail, return receipt requested.

Any notice required to be given to any director may be given by either of the methods hereinabove stated, except that such notice other than one which is delivered personally, shall be sent to such address or (in the case of electronic communication) such e-mail address, facsimile telephone number or other form of electronic address as such director shall have filed in writing or by electronic communication with the Secretary of the Corporation, or, in the absence of such filing, to the last known post office address of such director. If no address of a stockholder or director be known, such notice may be sent to the principal executive office of the Corporation. An affidavit of mailing, executed by a duly authorized and competent employee of the Corporation or its transfer agent appointed with respect to the class of stock affected, specifying the name and address or the names and addresses of the stockholder or stockholders, director or directors, to whom any such notice or notices was or were given, and the time and method of giving the same, shall be conclusive evidence of the statements therein contained. All notices given by mail, as above provided, shall be deemed to have been given as at the time of mailing and all notices given by means of electronic transmission shall be deemed to have been given as at the sending time recorded by the electronic transmission equipment operator transmitting the same. It shall not be necessary that the same method of giving notice be employed in respect of all directors or stockholders, as applicable, but one permissible method may be employed in respect of any one or more, and any other permissible method or methods may be employed in respect of any other or others. The period or limitation of time within which any stockholder may exercise any option or right, or enjoy any privilege or benefit, or be required to act, or within which any director may exercise any power or right, or enjoy any privilege, pursuant to any notice sent to such stockholder in the manner above provided, shall not be affected or extended in any manner by the failure of such a stockholder or such director to receive such notice. Whenever any notice is required to be given under the provisions of the statutes or of the Certificate of Incorporation, or of these Bylaws, a waiver thereof in writing signed by the person or persons entitled to said notice, or a waiver by electronic transmission by the person entitled to notice, whether before or after the time stated therein, shall be deemed equivalent thereto. Whenever notice is required to be given, under any provision of law or of the Certificate of Incorporation or Bylaws of the Corporation, to any person with whom communication is unlawful, the giving of such notice to such person shall not be required and there shall be no duty to apply to any governmental authority or agency for a license or permit to give such notice to such person. Any action or meeting which shall be taken or held without notice to any such person with whom communication is unlawful shall have the same force and effect as if such notice had been duly given. In the event that the action taken by the Corporation is such as to require the filing of a certificate under any provision of the Delaware General Corporation Law, the certificate shall state, if such is the fact and if notice is required, that notice was given to all persons entitled to receive notice except such persons with whom communication is unlawful.
