ARTICLE II

Stockholders

     2.1 Annual Meetings. An annual meeting of stockholders shall be held for the election of directors at such date and time as may be designated by the Board of Directors from time to time. The annual meeting of stockholders may be held at such place, either within or without the State of Delaware, or by means of remote communication, as may be designated by the Board of Directors from time to time; in the absence of any such designation, the annual meeting shall be held at the principal executive offices of the Corporation. At such meeting, the stockholders shall elect directors and transact such other business as may be properly brought before the meeting.

     To be properly brought before the annual meeting, business must be either (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 of the Corporation who (1) is a stockholder of record at the time of giving of notice provided for in this Section 2.1 and at the time of the annual meeting, (2) is entitled to vote at the meeting, and (3) complies with the notice procedures set forth in this Section 2.1. In addition to any other applicable requirements, for business to be properly brought before the annual meeting by a stockholder, the stockholder must have given timely notice thereof in writing to the Secretary of the Corporation. To be timely, a stockholder’s notice must be delivered by a nationally recognized courier service or mailed by first class United States mail, postage or delivery

charges prepaid, and received at the principal executive offices of the Corporation, addressed to the attention of the Secretary of the Corporation, not less than 90 days nor more than 120 days prior to the first anniversary of the date of the preceding year’s annual meeting. If, however, the date of the annual meeting is more than 25 days before or after such anniversary date, notice by a stockholder shall be timely only if so delivered or so mailed and received not later than the close of business on the 10th day following the date of the first public announcement of the date of the annual meeting. Except to the extent otherwise required by law, the adjournment of an annual meeting shall not commence a new time period for the giving of a stockholder’s notice as described above.

     A stockholder’s notice to the Secretary shall set forth as to each matter the stockholder proposes to bring before the annual meeting (i) 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, (ii) the name and record address of the stockholder proposing such business and any beneficial owner on whose behalf the proposal is made, (iii) ownership information as of the date of such notice with respect to the stockholder and any such beneficial owner, (iv) a description of all agreements, arrangements, or understandings (whether written or oral) between or among such stockholder or any beneficial owner, or any affiliates or associates of such person, and any other person or persons (including their names) in connection with the proposal of such business and any material interest of such stockholder or beneficial owner, or any affiliates or associates of such person, in such business, including any anticipated benefit therefrom to such person, or any affiliates or associates of such person, and (v) a representation that the stockholder giving notice intends to appear in person or by proxy at the annual meeting to bring such business before the meeting. Notwithstanding anything in these by-laws to the contrary, no business shall be conducted at the annual meeting except in accordance with the procedures set forth in this Section 2.1; provided, however, that nothing in this Section 2.1 shall be deemed to preclude discussion by any stockholder of any business properly brought before the annual meeting.

     A stockholder providing notice of business proposed to be brought before an annual meeting shall further update and supplement such notice, if necessary, so that the information provided or required to be provided in such notice pursuant to this Section 2.1 shall be true and correct as of the record date for determining the stockholders entitled to receive notice of the annual meeting and such update and supplement shall be delivered to or be mailed and received by the Secretary at the principal executive offices of the Corporation not later than ten (10) business days after the record date for determining the stockholders entitled to receive notice of the annual meeting.

     The Chairman of the Board of Directors (or such other person presiding at the meeting in accordance with Section 2.7 of these by-laws) 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 this Section 2.1, 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.

     For purposes of this Section 2.1 and Section 3.2, “public announcement” means disclosure (i) when made in a press release reported by the Dow Jones News Service, Associated

Press, or comparable national news service, (ii) when filed in a document publicly 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, or (iii) when mailed or otherwise delivered as the notice of the meeting pursuant to Section 2.3.

     For purposes of this Section 2.1 and Section 3.2, “ownership information” with respect to any person means (A) the class or series (if any) and number of shares of the Corporation that are owned beneficially or of record by such person and any affiliates or associates of such person, (B) 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 or with a value derived in whole or in part from the value of any class or series of shares of the Corporation, whether or not such instrument or right shall be subject to settlement in the underlying class or series of capital stock of the Corporation or otherwise (a “Derivative Instrument”) owned beneficially by such person and any other opportunity to profit or share in any profit derived from any increase or decrease in the value of shares of the Corporation, (C) any proxy, contract, arrangement, understanding, or relationship pursuant to which such person has a right to vote any shares of the Corporation, (D) any short interest in any security of the Corporation (for purposes of these by-laws, a person shall be deemed to have a “short interest” in a security if such person has the opportunity to profit or share in any profit derived from any decrease in the value of the subject security), (E) any rights to dividends on the shares of the Corporation owned beneficially by such person that are separated or separable from the underlying shares of the Corporation, (F) any proportionate interest in shares of the Corporation or Derivative Instruments held, directly or indirectly, by a general or limited partnership in which such person is a general partner or, directly or indirectly, beneficially owns an interest in a general partner and (G) any performance-related fees (other than an asset-based fee) that such person 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, including without limitation any such interests held by members of such person’s immediate family sharing the same household.

     Notwithstanding the foregoing provisions of this Section 2.1, a stockholder shall also comply with all applicable requirements of Delaware law and the Securities Exchange Act of 1934 and the rules and regulations thereunder with respect to the matters set forth in this Section 2.1.

     2.2 Special Meetings. Special meetings of stockholders may be called at any time only by the Chairman of the Board of Directors, if any, the Vice Chairman of the Board of Directors, if any, the President or the Board of Directors, to be held at such date, time and place (if any) as may be stated in the notice of the meeting. Business transacted at any special meeting of stockholders shall be limited to the purposes stated in the notice of the meeting.

     2.3 Notice of Meetings. Whenever stockholders are required or permitted to take any action at a meeting, notice of the meeting shall be given in accordance with Section 2.4 which shall state the place (if any), date and hour of the meeting, the means of remote communication (if any) by which stockholders and proxyholders may be deemed to be present in person and vote at such meeting and, in the case of a special meeting, the purpose or purposes for which the

meeting is called. Unless otherwise provided by law, the notice of any meeting shall be given not less than ten nor more than sixty days before the date of the meeting to each stockholder entitled to vote at such meeting.

     2.4 Manner Of Giving Notice. Notice of any meeting of stockholders shall be given personally, by mail, by electronic transmission or by other written communication, addressed to the stockholder at the address, number, electronic mail address or other location of that stockholder appearing on the books of the Corporation or given by the stockholder to the Corporation for the purpose of notice. If no such address, number, email address or other location appears on the Corporation’s books or is given, notice shall be deemed to have been given if sent to that stockholder by mail or telegraphic or other written communication to the Corporation’s principal executive office, or if published at least once in a newspaper of general circulation in the county where that office is located. Notice shall be deemed to have been given at the time when delivered personally or deposited in the mail or, if sent by electronic transmission, as follows: (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.

     An affidavit of mailing or of electronic transmission of any notice or report in accordance with the provisions of this Section 2.4, executed by the Secretary, Assistant Secretary or any transfer agent or other agent, shall be prima facie evidence of the giving of the notice.

     2.5 Adjournments. Any meeting of stockholders, annual or special, may adjourn from time to time to reconvene at the same or some other place (if any), and notice need not be given of any such adjourned meeting if the time and place (if any) thereof are announced at the meeting at which the adjournment is taken. At the adjourned meeting the Corporation may transact any business which might have been transacted at the original meeting. If the adjournment is for more than thirty 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.

     2.6 Quorum. At each meeting of stockholders, except where otherwise provided by law or the certificate of incorporation or these by-laws, the holders of a majority of the outstanding shares of each class of stock entitled to vote at the meeting, present in person or represented by proxy, shall constitute a quorum. For purposes of the foregoing, two or more classes or series of stock shall be considered a single class if the holders thereof are entitled to vote together as a single class at the meeting. In the absence of a quorum the stockholders so present may, by majority vote, adjourn the meeting from time to time in the manner provided by Section 2.5 of these by-laws until a quorum shall attend. Shares of its own capital stock belonging on the record date for the meeting to the Corporation or to another corporation, if a majority of the shares entitled to vote in the election of directors of such other corporation is held, directly or indirectly, by the Corporation, shall neither be entitled to vote nor be counted for quorum purposes; provided, however, that the foregoing shall not limit the right of the

Corporation to vote stock, including but not limited to its own stock, held by it in a fiduciary capacity.

     If authorized by the Board of Directors in its sole discretion, and subject to such guidelines and procedures as the Board of Directors may adopt, stockholders and proxyholders not physically present at a meeting of stockholders may, by means of remote communication:

(1) participate in a meeting of stockholders; and

(2) be deemed present in person and vote at a meeting of stockholders whether such meeting is to be held at a designated place or solely by means of remote communication, provided that (i) the Corporation shall implement reasonable measures to verify that each person deemed present and permitted to vote at the meeting by means of remote communication is a stockholder or proxyholder, (ii) the Corporation shall implement reasonable measures to provide such stockholders and proxyholders a reasonable opportunity to participate in the meeting and to vote on matters submitted to the stockholders, including an opportunity to read or hear the proceedings of the meeting substantially concurrently with such proceedings, and (iii) if any stockholder or proxyholder votes or takes other action at the meeting by means of remote communication, a record of such vote or other action shall be maintained by the Corporation.

     2.7 Organization. Meetings of stockholders shall be presided over by the Chairman of the Board of Directors, if any, or in the absence of the Chairman of the Board of Directors by the President, or in the absence of the President by a Vice President, or in the absence of the foregoing persons by a chairman designated by the Board of Directors, or in the absence of such designation by a chairman chosen at the meeting. The Secretary shall act as secretary of the meeting, or in the absence of the Secretary by an Assistant Secretary, or in their absence the chairman of the meeting may appoint any person to act as secretary of the meeting.

     2.8 Voting; Proxies. Unless otherwise provided in the certificate of incorporation, each stockholder entitled to vote at any meeting of stockholders shall be entitled to one vote for each share of stock held by such stockholder which has voting power upon the matter in question. Each stockholder entitled to vote at a meeting of stockholders or to express consent or dissent to corporate action in writing without a meeting may authorize another person or persons to act for such stockholder by proxy, but no such proxy shall be voted or acted upon after 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, whether in person or by other means provided for in these by-laws or the certificate of incorporation, and voting or by filing an instrument in writing revoking the proxy or another duly executed proxy bearing a later date with the Secretary of the Corporation. Voting at meetings of stockholders need not be by written ballot and need not be conducted by inspectors unless the holders of a majority of the outstanding shares of all classes of stock entitled to vote thereon present in person or by proxy at such meeting shall so determine. If authorized by the Board of Directors, votes may be submitted by electronic

transmission, provided that any such electronic transmission must either set forth or be submitted with information from which it can be determined that the electronic transmission was authorized by the stockholder or proxyholder. With respect to all matters other than the election of directors, unless otherwise provided by law or by the certificate of incorporation or these by-laws, the affirmative vote of the holders of a majority of the shares of all classes of stock present in person or represented by proxy at the meeting and entitled to vote on the subject matter shall be the act of the stockholders, provided that (except as otherwise required by law or by the certificate of incorporation) the Board of Directors may require a larger vote upon any such matter. Where a separate vote by class is required, the affirmative vote of the holders of a majority of the shares of each class present in person or represented by proxy at the meeting shall be the act of such class, except as otherwise provided by law or by the certificate of incorporation or these by-laws.

     Each director shall be elected by the vote of the majority of the votes cast with respect to the director at any meeting for the election of directors at which a quorum is present, provided that the directors shall be elected by the vote of a plurality of the votes cast for the nominees at any meeting for the election of directors where, as of the date that is one day before the date that the Corporation first files its definitive proxy statement (regardless of whether or not thereafter revised or supplemented) with the Securities and Exchange Commission, the number of nominees exceeds the number of directors to be elected at the meeting. For purposes of the preceding sentence, a majority of the votes cast means that the number of shares voted “for” a director must exceed the number of votes cast “against” that director.

     2.9 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 stockholders or any adjournment thereof, or to express consent to corporate action in writing without a meeting, 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, in advance, a record date, which shall not be more than sixty nor less than ten days before the date of such meeting, nor more than sixty days prior to any other action. If no record date is fixed: (1) the record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be at the close of business on the day next preceding the day on which notice is given, or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held; (2) the record date for determining stockholders entitled to express consent to corporate action in writing without a meeting, when no prior action by the Board of Directors is necessary, shall be the day on which the first written consent is expressed; and (3) 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 of the meeting; provided, however, that the Board of Directors may fix a new record date for the adjourned meeting.

     2.10 List of Stockholders Entitled To Vote. The Secretary shall prepare and make, at least ten days before every meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting, arranged in alphabetical order, and showing the address of each stockholder

and the number of shares registered in the name of each stockholder. Nothing contained herein shall require the Corporation to include electronic mail address 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 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 the meeting is to be held at a place, 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 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.

     2.11 Consent of Stockholders in Lieu of Meeting. Unless otherwise provided in the certificate of incorporation, any action required by law 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 in writing, setting forth the action so taken, shall be signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted. 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.

ARTICLE III

Board of Directors

     3.1 Powers; Number; Qualifications. The business and affairs of the Corporation shall be managed by or under the direction of the Board of Directors, except as may be otherwise provided by law or in the certificate of incorporation. The Board of Directors shall consist of one or more members, the number thereof to be determined from time to time by resolution of the Board of Directors. Directors need not be stockholders.

     3.2 Election; Term of Office; Resignation; Removal; Vacancies; Nominations. Each director shall hold office until the annual meeting of stockholders next succeeding his or her election and until his or her successor is elected and qualified or until his or her earlier resignation or removal. Any director may resign at any time upon notice in writing or electronic transmission to the Board of Directors or to the President or the Secretary of the Corporation. Such resignation shall take effect at the time specified therein, and unless otherwise specified therein no acceptance of such resignation shall be necessary to make it effective. Any director or the entire Board of Directors may be removed, with or without cause, by the holders of a majority of the shares then entitled to vote at an election of directors. Unless otherwise provided in the certificate of incorporation or these by-laws, vacancies and newly created directorships resulting from any increase in the authorized number of directors or from any other cause may be

filled by a majority of the directors then in office, although less than a quorum, or by the sole remaining director.

     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 at the annual meeting, by or at the direction of the Board of Directors, may be made by any Nominating Committee or person appointed by the Board of Directors; nominations may also be made by any stockholder of the Corporation who (1) is a stockholder of record at the time of giving of notice provided for in this Section 3.2 and at the time of the meeting, (2) is entitled to vote for the election of directors at the meeting, and (3) complies with the notice procedures set forth in this Section 3.2. Such nominations, other than those made by or at the direction of the Board of Directors, shall be made pursuant to timely notice in writing to the Secretary of the Corporation. To be timely, a stockholder’s notice must be delivered by a nationally recognized courier service or mailed by first class United States mail, postage or delivery charges prepaid, and received at the principal executive offices of the Corporation addressed to the attention of the Secretary of the Corporation not less than 90 days nor more than 120 days prior to the first anniversary of the date of the preceding year’s annual meeting. If, however, the date of the annual meeting is more than 25 days before or after such anniversary date, notice by a stockholder shall be timely only if so delivered or so mailed and received not later than the close of business on the 10th day following the date of the first public announcement of the date of the annual meeting. In the case of a special meeting of stockholders called for the purpose of electing directors, notice by a stockholder shall be timely only if so delivered or so mailed and received within 10 days following the date of the first public announcement of the date of the special meeting. Except to the extent otherwise required by law, the adjournment of an annual meeting or a special meeting shall not commence a new time period for the giving of a stockholder’s notice as described above.

     Such stockholder’s notice to the Secretary shall set forth (a) as to each person whom the stockholder proposes to nominate for election or reelection 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) ownership information with respect to the person, (iv) a statement as to the person’s citizenship, (v) any other information relating to the person that is required to be disclosed in solicitations for proxies for election of directors pursuant to Section 14 of the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (including such person’s written consent to be named in the proxy statement as a nominee and to serve as a director if elected), and (vi) a written statement from each proposed nominee as to whether such proposed nominee, if elected, intends to tender, promptly following such proposed nominee’s election or re-election, an irrevocable resignation effective upon such proposed nominee’s failure to receive the required vote for re-election at any meeting at which such proposed nominee would face re-election and upon acceptance of such resignation by the Board of Directors, in accordance with the Corporation’s Policy of the Board of Directors on Director Elections; and (b) as to the stockholder giving the notice and any beneficial owner on whose behalf the nomination is made, (i) the name and record address of the stockholder and any such beneficial owner, (ii) ownership information as of the date of such notice with respect to the stockholder and any such beneficial owner, (iii) a description of all agreements, arrangements, or understandings (whether written or oral) between or among such

stockholder or any beneficial owner, or any affiliates or associates of such person, and any proposed nominee or any other person or persons (including their names) pursuant to which the nomination(s) are being made by such person, and any material interest of such stockholder or beneficial owner, or any affiliates or associates of such person, in such nomination, including any anticipated benefit therefrom to such person, or any affiliates or associates of such person; (iv) a representation that the stockholder giving notice intends to appear in person or by proxy at the annual meeting or special meeting to nominate the persons named in its notice, (v) a representation whether the stockholder or the beneficial owner, if any, intends, or is part of a group that intends, to deliver a proxy statement or form of proxy to holders of at least the percentage of the Corporation’s outstanding shares required to elect the nominee or otherwise solicit proxies from stockholders in support of the nomination, and (vi) any other information relating to the person that is required to be disclosed in solicitations for proxies for election of directors pursuant to Section 14 of the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder. The Corporation may require any proposed nominee to furnish such other information as may reasonably be required by the Corporation to determine whether such proposed nominee meets the criteria set forth in the Corporation’s Corporate Governance Guidelines to serve as a director of the Corporation, including with regards to the independence of such proposed nominee. No person shall be eligible for election as a director of the Corporation unless nominated in accordance with the procedures set forth herein.

     A stockholder providing notice of any nomination proposed to be made at an annual meeting or special meeting shall further update and supplement such notice, if necessary, so that the information provided or required to be provided in such notice pursuant to this Section 3.2 shall be true and correct as of the record date for determining the stockholders entitled to receive notice of the annual meeting or special meeting and such update and supplement shall be delivered to or be mailed and received by the Secretary at the principal executive offices of the Corporation not later than ten (10) business days after the record date for determining the stockholders entitled to receive notice of the annual meeting or special meeting.

     In connection with any annual meeting, the Chairman of the Board of Directors (or such other person presiding at such meeting in accordance with Section 2.7 of these by-laws) shall, if the facts warrant, determine and declare to the meeting that a nomination was not made in accordance with the foregoing procedure, and if he or she should so determine, he or she shall so declare to the meeting and the defective nomination shall be disregarded.

     Notwithstanding any provision of this Section 3.2 to the contrary, a nomination of persons for election to the Board of Directors may be submitted for inclusion in the Corporation’s proxy materials pursuant to the final rules adopted by the Securities and Exchange Commission (the “SEC”) providing for such nominations and inclusion (“final proxy access rules”), and, if such nomination is submitted under the final proxy access rules, such submission (a) in order to be timely, must be delivered to, or be mailed and received by, the Secretary at the principal executive offices of the Corporation no later than 120 calendar days before the date that the Corporation mailed (or otherwise disseminated) its proxy materials for the prior year’s annual meeting (or such other date as may be set forth in the final proxy access rules for companies without advance notice bylaws); (b) in all other respects, must be made pursuant to, and in

accordance with, the terms of the final proxy access rules, as in effect at the time of the nomination, or any successor rules or regulations of the SEC then in effect; and (c) must provide the Corporation with any other information required by this Section 3.2 for nominations not made under the final proxy access rules except to the extent that requiring such information to be furnished is prohibited by the final proxy access rules. The provisions of this paragraph do not provide stockholders of the Corporation with any rights, nor impose upon the Corporation any obligations, other than the rights and obligations set forth in the final proxy access rules.

     3.3 Regular Meetings. Regular meetings of the Board of Directors may be held at such places within or without the State of Delaware and at such times as the Board of Directors may from time to time determine, and if so determined notice thereof need not be given.

     3.4 Special Meetings. Special meetings of the Board of Directors may be held at any time or place within or without the State of Delaware whenever called by the Chairman of the Board of Directors, if any, by the Vice Chairman of the Board of Directors, if any, by the President or by any two directors. Reasonable notice thereof shall be given by the person or persons calling the meeting.

     3.5 Participation in Meetings by Conference Telephone Permitted. Unless otherwise restricted by the certificate of incorporation or these by-laws, members of the Board of Directors, or any committee designated by the Board of Directors, may participate in a meeting of the Board of Directors or of such committee, as the case may be, by means of conference telephone or similar communications equipment by means of which all persons participating in the meeting can hear each other, and participation in a meeting pursuant to this by-law shall constitute presence in person at such meeting.

     3.6 Quorum; Vote Required for Action. At all meetings of the Board of Directors one third of the entire Board of Directors, but not less than two shall constitute a quorum for the transaction of business. The vote of a majority of the directors present at a meeting at which a quorum is present shall be the act of the Board of Directors unless the certificate of incorporation or these by-laws shall require a vote of a greater number. In case at any meeting of the Board of Directors a quorum shall not be present, the members of the Board of Directors present may adjourn the meeting from time to time until a quorum shall attend.

     3.7 Organization. Meetings of the Board of Directors shall be presided over by the Chairman of the Board of Directors, if any, or in the absence of the Chairman of the Board of Directors by the Vice Chairman of the Board of Directors, if any, or in the absence of the Vice Chairman of the Board of Directors by the President, or in their absence by a chairman chosen at the meeting. The Secretary, or in the absence of the Secretary an Assistant Secretary, shall act as secretary of the meeting, but in the absence of the Secretary and any Assistant Secretary the chairman of the meeting may appoint any person to act as secretary of the meeting.

     3.8 Action by Directors Without a Meeting. Unless otherwise restricted by the certificate of incorporation or these by-laws, any action required or permitted to be taken at any meeting of the Board of Directors, or of any committee thereof, may be taken without a meeting if all members of the Board of Directors or of such committee, as the case may be, consent

thereto in writing or electronic transmission, and the writing or writings or electronic transmission or transmissions are filed with the minutes of proceedings of the Board of Directors or committee. All such actions by written consent or electronic transmission shall have the same force and effect as a unanimous vote of such directors.

     3.9 Compensation of Directors. The Board of Directors shall have the authority to fix the compensation of directors.

ARTICLE IV

Committees

     4.1 Executive Committee. The Board of Directors may, by resolution approved by at least a majority of the authorized number of directors, establish and appoint one or more members of the Board of Directors to constitute an Executive Committee (the “Executive Committee”), with such powers as may be expressly delegated to it by resolution of the Board of Directors. The Executive Committee shall act only in the intervals between meetings of the Board of Directors and shall be subject at all times to the control of the Board of Directors.

     4.2 Committees. In addition to the Executive Committee, the Board of Directors may, by resolution passed by a majority of the whole Board of Directors, designate one or more other committees, each committee to consist of one or more of the directors of the Corporation. The Board of Directors may designate one or more directors as alternate members of any committee, who may replace any absent or disqualified member at any meeting of the committee. In the absence or disqualification of a member of a committee, the member or members thereof present at any meeting and not disqualified from voting, whether or not such member or members constitute a quorum, may unanimously appoint another member of the Board of Directors to act at the meeting in place of any such absent or disqualified member. Any such committee, to the extent provided in the resolution of the Board of Directors, shall have and may exercise all the powers and authority of the Board of Directors in the management of the business and affairs of the Corporation, and may authorize the seal of the Corporation to be affixed to all papers which may require it; but no such committee shall have power or authority in reference to amending the certificate of incorporation (except that a committee may, to the extent authorized in the resolution or resolutions providing for the issuance of shares of stock adopted by the Board of Directors as provided in Section 151(a) of the General Corporation Law of Delaware fix any of the preferences or rights of such shares relating to dividends, redemption, dissolution, any distribution of assets of the Corporation or the conversion into, or the exchange of such shares for, shares of any other class or classes or any other series of the same or any other class or classes of stock of the Corporation), adopting an agreement of merger or consolidation, recommending to the stockholders the sale, lease or exchange of all or substantially all of the Corporation’s property and assets, recommending to the stockholders a dissolution of the Corporation or a revocation of dissolution, removing or indemnifying directors or amending these by-laws; and, unless the resolution expressly so provides, no such committee shall have the power or authority to declare a dividend or to authorize the issuance of stock or adopt a certificate of ownership and merger.

     4.3 Committee Rules. Unless the Board of Directors otherwise provides, the committee designated by the Board of Directors may adopt, amend and repeal rules for the conduct of its business. In the absence of a provision by the Board of Directors or a provision in the rules of such committee to the contrary, a majority of the entire authorized number of members of such committee shall constitute a quorum for the transaction of business, the vote of a majority of the members present at a meeting at the time of such vote if a quorum is then present shall be the act of such committee, and in other respects each committee shall conduct its business in the same manner as the Board of Directors conducts its business pursuant to Article III of these by-laws.

ARTICLE V

Officers

     5.1 Officers; Election. As soon as practicable after the annual meeting of stockholders in each year, the Board of Directors shall elect a President and a Secretary, and it may, if it so determines, elect from among its members a Chairman of the Board of Directors. The Board of Directors may also elect one or more Vice Presidents, one or more Assistant Vice Presidents, one or more Assistant Secretaries, a Treasurer and one or more Assistant Treasurers and such other officers as the Board of Directors may deem desirable or appropriate and may give any of them such further designations or alternate titles as it considers desirable. Any number of offices may be held by the same person; provided, however, that the offices of President and Secretary shall not be held by the same person.

     5.2 Term of Office; Resignation; Removal; Vacancies. Except as otherwise provided in the resolution of the Board of Directors electing any officer, each officer shall hold office until the first meeting of the Board of Directors after the annual meeting of stockholders next succeeding his or her election, and until his or her successor is elected and qualified or until his or her earlier resignation or removal. Any officer may resign at any time upon written notice to the Board of Directors or to the President or the Secretary of the Corporation. Such resignation shall take effect at the time specified therein, and unless otherwise specified therein no acceptance of such resignation shall be necessary to make it effective. The Board of Directors may remove any officer with or without cause at any time. Any such removal shall be without prejudice to the contractual rights of such officer, if any, with the Corporation, but the election of an officer shall not of itself create contractual rights. Any vacancy occurring in any office of the Corporation by death, resignation, removal or otherwise may be filled for the unexpired portion of the term by the Board of Directors at any regular or special meeting.

     5.3 Powers and Duties. The officers of the Corporation shall have such powers and duties in the management of the Corporation as shall be stated in these by-laws or in a resolution of the Board of Directors which is not inconsistent with these by-laws and, to the extent not so stated, as generally pertain to their respective offices, subject to the control of the Board of Directors.

He shall have power to sign all stock certificates, contracts and other instruments of the Corporation which are authorized and shall have general supervision and direction of all of the other officers, employees and agents of the Corporation. The President shall be ex officio, a member of all the standing committees, including the Executive Committee. In the absence of the Chairman of the Board of Directors, the President shall preside at all meetings of the Board of Directors.

     5.6 Vice President. In the absence of the President or in his inability or refusal to act, the Vice President (or in the event there be more than one Vice President, the Vice Presidents in the order designated by the directors, or in the absence of any designation, then in the order of their election) shall perform the duties of the President, and when so acting, shall have all the powers of and be subject to all the restrictions upon the President. The Vice Presidents shall perform such other duties and have such other powers as the Board of Directors may from time to time prescribe.

     5.7 Secretary. The Secretary shall attend all meetings of the Board of Directors and all meetings of the stockholders and record all the proceedings of the meetings of the Corporation and of the Board of Directors in a book to be kept for that purpose and shall perform like duties for the standing committees when required. He shall give, or cause to be given, notice of all meetings of the stockholders and special meetings of the Board of Directors, and shall perform such other duties as may be prescribed by the Board of Directors or president, under whose supervision he shall be. He shall have custody of the corporate seal of the Corporation and he, or an Assistant Secretary, shall have authority to affix the same to any instrument requiring it and when so affixed, it may be attested by his signature or by the signature of such Assistant Secretary. The Board of Directors may give general authority to any other officer to affix the seal of the Corporation and to attest the affixing by his signature.

     5.8 Assistant Secretary. The Assistant Secretary, or if there be more than one, the Assistant Secretaries in the order determined by the Board of Directors (or if there be no such determination, then in the order of their election) shall, in the absence of the Secretary or in the event of his inability or refusal to act, perform the duties and exercise the powers of the Secretary and shall perform such other duties and have such other powers as the Board of Directors may from time to time prescribe.

     5.9 Treasurer. The Treasurer shall have the custody of the corporate funds and securities and shall keep full and accurate accounts of receipts and disbursements in books belonging to the Corporation and shall deposit all moneys and other valuable effects in the name and to the credit of the Corporation in such depositories as may be designated by the Board of Directors. He shall disburse the funds of the Corporation as may be ordered by the Board of Directors, taking proper vouchers for such disbursements, and shall render to the President and the Board of Directors, at its regular meetings, or when the Board of Directors so requires, an account of all his transactions as Treasurer and of the financial condition of the Corporation.

     5.10 Assistant Treasurer. The Assistant Treasurer, or if there shall be more than one, the Assistant Treasurers in the order determined by the Board of Directors (or if there be no such determination, then in the order of their election) shall, in the absence of the Treasurer or in the event of his inability or refusal to act, perform the duties and exercise the powers of the Treasurer and shall perform such other duties and have such other powers as the Board of Directors may from time to time prescribe.

ARTICLE VI

Stock

     6.1 Certificates. The shares of stock of the Corporation shall either be represented by certificates or uncertificated, as determined by the Board of Directors; provided, however, that every holder of stock in the Corporation shall be entitled to have a certificate signed by or in the name of the Corporation by the Chairman or Vice Chairman of the Board of Directors, if any, or the President or a Vice President, and by the Treasurer or an Assistant Treasurer, or the Secretary or any Assistant Secretary, of the Corporation, certifying the number of shares owned by such holder in the Corporation. If such certificate is manually signed by one officer or manually countersigned by a transfer agent or by a registrar, any other signature on the certificate may be a facsimile. In case any officer, transfer agent or registrar who has signed or whose facsimile signature has been placed upon a certificate shall have ceased to be such officer, transfer agent or registrar before such certificate is issued, it may be issued by the Corporation with the same effect as if such person were such officer, transfer agent or registrar at the date of issue.

     Upon the face or back of each stock certificate issued to represent any partly paid shares, or upon the books and records of the Corporation in the case of uncertificated partly paid shares, shall be set forth the total amount of the consideration to be paid therefor and the amount paid thereon shall be stated. If the Corporation shall be authorized to issue more than one class of stock or more than one series of any class, the powers, designations, preferences and relative, participating, optional or other special rights of each class of stock or series thereof and the qualification, limitations or restrictions of such preferences and/or rights shall be set forth in full or summarized on the face or back of the certificate which the Corporation shall issue to represent such class or series of stock, provided that, except as otherwise provided in Section 202 of the General Corporation Law of Delaware, in lieu of the foregoing requirements, there may be set forth on the face or back of the certificate which the Corporation shall issue to represent such class or series of stock, a statement that the Corporation will furnish without charge to each stockholder who so requests the powers, designations, preferences and relative, participating,

optional or other special rights of each class of stock or series thereof and the qualifications, limitations or restrictions of such preferences and/or rights.

     6.2 Lost, Stolen or Destroyed Stock Certificates; Issuance of New Certificates. The Corporation may issue a new certificate of stock in the place of any certificate theretofore issued by it, alleged to have been lost, stolen or destroyed, and the Corporation may require the owner of the lost, stolen or destroyed certificate, or such owner’s legal representative, to give the Corporation a bond sufficient to indemnify it against any claim that may be made against it on account of the alleged loss, theft or destruction of any such certificate or the issuance of such new certificate.

     6.3 Transfer of Stock. Upon surrender to the Corporation or the transfer agent of the Corporation of a certificate for shares duly endorsed or accompanied by proper evidence of succession, assignation or authority to transfer, it shall be the duty of the Corporation to issue a new certificate to the person entitled thereto, cancel the old certificate and record the transaction upon its books. Transfer of uncertificated shares of stock shall be made on the books of the Corporation upon receipt of proper transfer instructions from the registered owner of the uncertificated shares, an instruction from an approved source duly authorized by such owner or from an attorney lawfully constituted in writing. The Corporation may impose such additional conditions to the transfer of its stock as may be necessary or appropriate for compliance with applicable law or to protect the Corporation, a transfer agent or the registrar from liability with respect to such transfer.

     6.4 Fixing Record Date. In order that the Corporation may determine the stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof, or to express consent to corporate action in writing without a meeting, 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, in advance, a record date, which shall not be more than sixty nor less than ten days before the date of such meeting, nor more than sixty days prior to any other action. A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the Board of Directors may fix a new record date for the adjourned meeting.

     6.5 Registered Stockholders. The Corporation shall be entitled to recognize the exclusive right of a person registered on its books as the owner of shares to receive dividends, and to vote as such owner, and to hold liable for calls and assessments a person registered on its books as the owner of shares, and shall not be bound to recognize any equitable or other claim to or interest in such share or shares on the part of any other person, whether or not it shall have express or other notice thereof, except as otherwise provided by the laws of Delaware.

ARTICLE VII

Miscellaneous

     7.1 Fiscal Year. The fiscal year of the Corporation shall be determined by the Board of Directors.

     7.2 Seal. The Corporation may have a corporate seal which shall have the name of the Corporation inscribed thereon and shall be in such form as may be approved from time to time by the Board of Directors. The corporate seal may be used by causing it or a facsimile thereof to be impressed or affixed or in any other manner reproduced.

     7.3 Waiver of Notice of Meetings of Stockholders, Directors and Committees. Whenever notice is required to be given by law or under any provision of the certificate of incorporation or these by-laws, a written waiver thereof, 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. Neither the business to be transacted at, nor the purpose of, any regular or special meeting of the stockholders, directors, or members of a committee of directors need be specified in any written waiver of notice unless so required by the certificate of incorporation or these by-laws.

     7.4 Interested Directors; Quorum. 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 his or her or their votes are counted for such purpose, if: (1) the material facts as to his or her 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 be less than a quorum; or (2) the material facts as to his or her 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 (3) 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.

     7.5 Amendment of By-Laws. These by-laws may be amended or repealed, and new by-laws adopted, by the Board of Directors, but the stockholders entitled to vote may adopt additional by-laws and may amend or repeal any by-law whether or not adopted by them.
