Meetings of Stockholders

SECTION 2.01. Place, Time and Notice. Subject to the laws governing the corporation, meetings of stockholders of the corporation shall be held at the registered office of the corporation or at such other place within or without the State of Delaware and at such time as the Chairman of the Board of Directors or the President of the corporation may determine from time to time or as the Secretary may determine within 10 calendar days after receipt of the written request of a majority of the directors, acting in accordance with such request. The Secretary or any Assistant Secretary shall cause notice of each meeting of stockholders to be given in writing in a manner permitted by the General Corporation Law of the State of Delaware, as amended from time to time (the “DGCL”), not less than 10 days nor more than 60 days prior to the meeting to each stockholder of record entitled to vote at such meeting, subject to such exclusions as are then permitted by the DGCL. The notice shall specify (i) the place, if any, date and time of such meeting, (ii) the means of remote communications,

if any, by which stockholders and proxy holders may be deemed to be present in person and vote at such meeting, (iii) in the case of a special meeting, the purpose or purposes for which such meeting is called, and (iv) such other information as may be required by law or as may be deemed appropriate by the Board of Directors. If the stockholder list referred to in Section 2.10 of these by-laws is made accessible on an electronic network, the notice of meeting shall indicate how the stockholder list can be accessed. If the meeting of stockholders is to be held solely by means of remote communication, the notice of meeting shall provide the information required to access such stockholder list during the meeting.

SECTION 2.02. Special Meetings. Special meetings of the stockholders of the corporation may be called only by the Secretary at the request of (i) a majority of the total number of directors which the corporation at the time would have if there were no vacancies on the Board of Directors (the “Whole Board”) or (ii) any person authorized by the Board of Directors (through a vote of a majority of the Whole Board). Stockholders shall have no right to call a special meeting of stockholders.

SECTION 2.03. Participation in Meetings by Remote Communication. The Board of Directors, acting in its sole discretion, may establish guidelines and procedures in accordance with applicable provisions of the DGCL and any other applicable law for the participation by stockholders and proxyholders in a meeting of stockholders by means of remote communications, and may determine that any meeting of stockholders will not be held at any place but will be held solely by means of remote communication. Stockholders and proxyholders complying with such procedures and guidelines and otherwise entitled to vote at a meeting of stockholders shall be deemed present in person and entitled to vote at a meeting of stockholders, whether such meeting is to be held at a designated place or solely by means of remote communication.

SECTION 2.04. Quorum, Manner of Acting and Adjournment. The holders of record of a majority of the stock issued and outstanding (not including treasury stock) and entitled to vote thereat, present in person or represented by proxy, shall constitute a quorum at all meetings of the stockholders for the transaction of business except as otherwise provided by statute, by the certificate of incorporation or by these by-laws. If, however, such quorum shall not be present or represented at any meeting of the stockholders, the stockholders entitled to vote thereat, present in person or represented by proxy, may, by a majority vote, adjourn the meeting from time to time, without notice other than announcement at the meeting, until a quorum shall be present or represented. At any such adjourned meeting, at which a quorum shall be present or represented, any business may be transacted which might have been transacted at the meeting as originally notified. 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 in accordance with Section 2.01 of these by-laws shall be given to each stockholder of record entitled to vote at the meeting. When a quorum is present at any meeting, the vote of the holders of the majority of the stock having voting power present in person or represented by proxy shall decide any question brought before such meeting, unless the question is one upon which, by express provision of the applicable statute or certificate of incorporation or these by-laws, a different vote is required in which case such express provision shall govern and control the decision of such question. Except upon those questions governed by the aforesaid express provisions,

the stockholders present in person or by proxy at a duly organized meeting can continue to do business until adjournment, notwithstanding withdrawal of enough stockholders to leave less than a quorum.

SECTION 2.05. Organization. At every meeting of the stockholders, the Chairman of the Board, if there be one, or in the case of a vacancy in the office or absence of the Chairman of the Board, one of the following persons present in the order stated: the Lead Director, if there be one, the President, the Managing Directors in their order of rank and seniority, the Senior Vice Presidents in their order of rank and seniority or a chairman designated by the Board of Directors, shall act as the presiding officer, and the Secretary, or, in his absence, an Assistant Secretary, or in the absence of the Secretary and the Assistant Secretaries, a person appointed by the presiding officer, shall act as Secretary.

SECTION 2.06. Voting/Proxies. Each stockholder shall, at every meeting of the stockholders, be entitled to one vote in person or by proxy for each share of capital stock having voting power held by such stockholder. Each stockholder entitled to vote at a meeting of stockholders or to express consent to or dissent from corporate action in writing without a meeting may authorize another person or persons to act for such stockholder by proxy. A stockholder may authorize a valid proxy by executing a written instrument signed by such stockholder, or by 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 transmitting or authorizing an electronic transmission (as defined in Section 9.08 of these by-laws) setting forth an authorization to act as proxy to the person designated as the holder of the proxy, a proxy solicitation firm or a like authorized agent. Proxies by 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. Any copy, facsimile telecommunication or other reliable reproduction of a writing or transmission created pursuant to this section 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 if such copy, facsimile telecommunication or other reproduction is a complete reproduction of the entire original writing or transmission. No proxy shall be voted after three years from its date, unless the proxy provides for a longer period. Every proxy is revocable at the pleasure of the stockholder executing it unless the proxy states that it is irrevocable and applicable law makes it irrevocable. A stockholder may revoke any proxy that is not irrevocable by attending the meeting and voting in person or by filing an instrument in writing revoking the proxy or by filing another duly executed proxy bearing a later date with the Secretary. A proxy shall not be revoked by the death or incapacity of the maker unless, before the vote is counted or the authority is exercised, written notice of such death or incapacity is given to the Secretary.

SECTION 2.07. Notice of Stockholder Business and Nominations.

(A) Annual Meeting of Stockholders.

(1) Nominations of persons for election to the Board of Directors of the corporation and the proposal of business to be considered by the stockholders may be made at an annual meeting of stockholders (a) by or at the direction of the Board of Directors pursuant to a resolution

adopted by a majority of the Whole Board or (b) by any stockholder of the corporation who is entitled to vote at the meeting with respect to the election of directors or the business to be proposed by such stockholder, as the case may be, who complies with the notice procedures set forth in clauses (2) and (3) of paragraph (A) of this Section 2.07 and who is a stockholder of record at the time such notice is delivered to the Secretary as provided below and at the date of the meeting.

(2) For nominations or other business to be properly brought before an annual meeting by a stockholder pursuant to clause (b) of paragraph (A) (1) of this Section 2.07, the stockholder must have given timely notice thereof in writing to the Secretary and such business must be a proper subject for stockholder action under the DGCL. To be timely, a stockholder’s notice shall be delivered to the Secretary at the principal executive office of the corporation not less than 90 days nor more than 120 days prior to the first anniversary of the preceding year’s annual meeting (or, in the case of the 2007 annual meeting, not less than 60 days nor more than 90 days); provided, however, that in the event that the date of the annual meeting is advanced by more than 30 days, or delayed by more than 30 days, from such anniversary date, notice by the stockholder to be timely must be so delivered not earlier than the 120th day prior to such annual meeting and not later than either the close of business on (a) the 10th day following the day on which notice of the date of such meeting was mailed or (b) the 10th day following the day on which public announcement of the date of such meeting is first made, whichever first occurs. Such stockholder’s notice shall set forth (i) as to each person whom the stockholder proposes to nominate for election or re-election as a director, all information relating to such person that is required to be disclosed in solicitations of proxies for election of directors, or is otherwise required, in each case pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended (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; (ii) as to any other business that the stockholder proposes to bring before the meeting, the text of the proposal (including the text of any resolutions proposed for consideration and if such business includes proposed amendments to the certification of incorporation and/or by-laws of the corporation, the text of the proposed amendments), the reasons for conducting such business at the meeting and any material interest in such business of such stockholder and the beneficial owner, if any, on whose behalf the proposal is made; (iii) the name and address of such stockholder, as they appear on the corporation’s books and records, and of such beneficial owner, (iv) the class or series and number of shares of capital stock of the corporation which are owned beneficially and of record by such stockholder and such beneficial owner, (v) a representation that the stockholder is a holder of record of stock of the corporation entitled to vote at such meeting and intends to appear in person or by proxy at the meeting to propose such business or nomination, and (vi) a representation as to whether the stockholder or the beneficial owner, if any, intends or is part of a group which intends (A) to deliver a proxy statement and/or form of proxy to holders of at least the percentage of the corporation’s outstanding capital stock required to elect the nominee or to approve or adopt the proposal or and/or (B) otherwise to solicit proxies from stockholders in support of such nomination or proposal. The foregoing notice requirements shall be deemed satisfied by a stockholder if the stockholder has notified the corporation of his or her intention to present a proposal at an annual meeting in compliance with Rule 14a-8 (or any successor thereof) promulgated under the Exchange Act and such stockholder’s proposal has been included in a proxy statement that has been prepared by the corporation to solicit proxies for such annual meeting.

(3) Notwithstanding anything in the second sentence of paragraph (A) (2) of this Section 2.07 to the contrary, in the event that the number of directors to be elected to the Board of Directors is increased and there is no public announcement naming all of the nominees for director or specifying the size of the increased Board of Directors made by the corporation at least 80 days prior to the first anniversary of the preceding year’s annual meeting, a stockholder’s notice required by paragraph (A) (2) of this Section 2.07 shall also be considered timely, but only with respect to nominees for any new positions created by such increase, if it shall be delivered to the Secretary at the principal executive offices of the corporation not later than the close of business on the 10th day following the day on which such public announcement is first made by the corporation.

(B) Special Meeting of Stockholders. Only such business shall be conducted at a special meeting of stockholders as shall have been brought before the meeting pursuant to the corporation’s notice of meeting and in accordance with these by-laws. Nominations of persons for election to the Board of Directors may be made at a special meeting of stockholders at which directors are to be elected pursuant to the corporation’s notice of meeting (a) by or at the direction of the Board of Directors pursuant to a resolution adopted by a majority of the Whole Board or (b) provided that the Board of Directors has determined that directors shall be elected at such meeting, by any stockholder of the corporation who is a stockholder of record at the time of giving of notice provided for in this Section 2.07, who shall be entitled to vote at the meeting and who complies with the notice procedures set forth in this Section 2.07. In the event the corporation calls a special meeting of stockholders for the purpose of electing one or more directors to the Board of Directors, any such stockholder may nominate a person or persons (as the case may be), for election to such position(s) as specified in the corporation’s notice of meeting, if the stockholder’s notice required by paragraph (A)(2) of this Section 2.07 shall be delivered to the Secretary at the principal executive offices of the corporation not earlier than the close of business on the 120th day prior to such special meeting and not later than the close of business on the later of the 90th day prior to such special meeting or the 10th day following the day on which public announcement is first made of the date of the special meeting and of the nominees proposed by the Board of Directors to be elected at such meeting. In no event shall the public announcement of an adjournment of a special meeting commence a new time period for the giving of a stockholder’s notice as described above.

(C) General.

(1) Only persons who are nominated in accordance with the procedures set forth in this Section 2.07 shall be eligible to serve as directors and only such business shall be conducted at a meeting of stockholders as shall have been brought before the meeting in accordance with the procedures set forth in this Section 2.07.

(2) Except as otherwise provided by law, the certificate of incorporation or this Section 2.07, the presiding officer shall have the power and duty to determine whether a nomination or any business proposed to be brought before the meeting was made in accordance with the procedures set forth in this Section 2.07 and, if any proposed nomination or business is not in compliance with this Section 2.07, to declare that such defective nomination or proposal shall be disregarded.

(3) For purposes of this Section 2.07, “public announcement” shall mean disclosure on a press release reported by the Dow Jones News Service, Associated Press or comparable national news service or in a document publicly filed by the corporation with the Securities and Exchange Commission pursuant to Section 13, 14 or 15(d) of the Exchange Act.

(4) Notwithstanding the foregoing provisions of this Section 2.07, a stockholder shall also comply with all applicable requirements of the Exchange Act and the rules and regulations thereunder with respect to the matters set forth in this Section 2.07. Nothing in this Section 2.07 shall be deemed to affect any rights (i) of stockholders to request inclusion of proposals in the corporation’s proxy materials with respect to a meeting of stockholders pursuant to Rule 14a-8 under Exchange Act or (ii) of the holders of any series of preferred stock or any other series or class of stock (excluding common stock) as set forth in the certificate of incorporation to elect directors under specified circumstances or to consent to specific actions taken by the corporation.

SECTION 2.08. Procedure for Election of Directors; Required Vote. Subject to the rights of the holders of any series of preferred stock or any other series or class of stock as set forth in the certificate of incorporation to elect directors under specified circumstances, election of directors at all meetings of the stockholders at which directors are to be elected shall be by a plurality of the votes cast. Except as otherwise provided by law, the certificate of incorporation, or these by-laws, in all matters other than the election of directors, the affirmative vote of a majority of the stock present in person or represented by proxy at the meeting and entitled to vote on the matter shall be the act of the stockholders.

SECTION 2.09. No Stockholder Action by Written Consent. Subject to the rights of the holders of any series of preferred stock or any other series or class of stock (excluding common stock) set forth in the certificate of incorporation to elect additional directors under specified circumstances or to consent to specific actions taken by the corporation, any action required or permitted to be taken by the stockholders of the corporation must be taken at an annual or special meeting of the stockholders and may not be taken by any consent in writing by stockholders of the corporation.

SECTION 2.10. Voting Lists. The officer who has charge of the stock ledger of the corporation shall prepare and make, at least ten days before every meeting of stockholders (and every adjournment thereof for which a new record date has been set), a complete list of the stockholders entitled to vote at the meeting. The list shall be arranged in alphabetical order showing the address of each stockholder and the number of shares registered in the name of each stockholder. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting, during ordinary business hours, for a period of at least ten days prior to the meeting either at a place within the city where the meeting is to be held, which place shall be specified in the notice of the meeting, or, if not so specified, at the place where the meeting is to be held. The list shall also be produced and kept at the time and place of the meeting during the whole time thereof, and may be inspected by any stockholder who is present. The stock ledger shall be the only evidence as to who are the stockholders entitled by this section to examine the list required by this section or to vote in person or by proxy at any meeting of stockholders.

SECTION 2.11. Inspector of Election. All elections of directors may be, but need not be, by written ballot, unless otherwise provided in the certificate of incorporation; the vote upon any other matter need not be by ballot. In advance of any meeting of stockholders, the Board of Directors may, and when required by law shall, appoint one or more persons to act as inspectors of elections, and may designate one or more alternate inspectors. If no inspector or alternate so appointed by the Board of Directors is able to act, or if no inspector or alternate has been appointed and the appointment of an inspector is required by law, the presiding officer at the meeting shall appoint one or more inspectors to act at the meeting. Each inspector, before entering upon the discharge of the duties of an inspector, shall take and sign an oath faithfully to execute the duties of inspector with strict impartiality and according to the best of his or her ability. The inspectors shall discharge their duties in accordance with the requirements of applicable law.

ARTICLE VII

Certificates of Stock, Transfer, Etc.

SECTION 7.01. Issuance. The shares of stock of the corporation shall be represented by certificates, except to the extent that the Board of Directors has provided by resolution that some or all of any or all classes or series of the stock of the corporation shall be uncertificated shares. Any such resolution shall not apply to any such shares represented by a certificate until such certificate is surrendered to the corporation. Every holder of stock of the corporation represented by certificates shall be entitled to have, and the Board of Directors may in its sole discretion permit, a holder of uncertificated shares to receive upon request, a certificate, signed by the Chairman of the Board, the President or a Vice President and by the Secretary or an Assistant Secretary or the Treasurer or an Assistant Treasurer of the corporation, representing the number of shares registered in certificate form. It shall not be necessary for such certificates to bear the corporate seal, unless required by law. Any of or all the signatures upon such certificate may be a facsimile, engraved or printed. In case any officer, transfer agent or registrar who has signed, or whose facsimile signature has been placed upon, any share certificate shall have ceased to be such officer, transfer agent or registrar, before the certificate is issued, it may be issued with the same effect as if he were such officer, transfer agent or registrar at the date of its issue.

SECTION 7.02. Transfer. 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. No transfer shall be made which would be inconsistent with the provisions of Article 8, Title 6 of the Delaware Uniform Commercial Code—Investment Securities.

SECTION 7.03. Stock Certificates. Stock certificates of the corporation shall be in such form as provided by statute and approved by the Board of Directors. The stock record books and the blank stock certificates books shall be kept by the Secretary or by any agency designated by the Board of Directors for that purpose.

SECTION 7.04. Lost, Stolen, Destroyed or Mutilated Certificates. The Board of Directors may direct a new certificate or certificates to be issued in place of any certificate or certificates theretofore issued by the corporation alleged to have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming the certificate of stock to be lost, stolen or destroyed. When authorizing such issue of a new certificate or certificates, the Board of Directors may, in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed certificate or certificates, or his legal representative, to advertise the same in such manner as it shall require and/or to give the corporation a bond in such sum as it may direct as indemnity against any claim that may be made against the corporation with respect to the certificate alleged to have been lost, stolen or destroyed.

SECTION 7.05. Record Holder of Shares. The corporation shall be entitled to recognize the exclusive right of a person registered on its books as the owner of shares to receive dividends or other distributions, to vote as such owner, and to receive notices 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 the corporation shall have express or other notice thereof, except as otherwise provided by the laws of the State of Delaware.

SECTION 7.06. 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, the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board of Directors, and which record date shall not be more than 60 days nor less than 10 days before the date of such meeting. If no record date is fixed, 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. 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 adjournment meeting.

In order that the corporation may determine the stockholders entitled to receive payment of any dividend or other distribution or allotment of any rights, or entitled to exercise any rights in respect of any change, conversion or exchange of stock or for the purpose of any other lawful action, the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board of Directors, and which record date shall not be more than 60 days prior to the action for which a record date is being established. If no record date is fixed, 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.

ARTICLE VIII

Indemnification

SECTION 8.01. Indemnification.

(A) In General. The corporation shall indemnify, to the full extent permitted by the DGCL and other applicable law, any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (each, a “proceeding”) by reason of the fact that (x) such person is or was serving or has agreed to serve as a director or officer of the corporation or (y) such person, while serving as a director or officer of the corporation, is or was serving or has agreed to serve at the request of the corporation as a director, officer, employee, manager or agent of another corporation, partnership, joint venture, trust or other enterprise or (z) such person is or was serving or has agreed to serve at the request of the corporation as a director, officer or manager of another corporation, partnership, joint venture, trust or other enterprise, or by reason of any action alleged to have been taken or omitted by such person in such capacity, and who satisfies the applicable standard of conduct set forth in the DGCL or other applicable law:

(1) in a proceeding other than a proceeding by or in the right of the corporation, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person or on such person’s behalf in connection with such proceeding and any appeal therefrom, or

(2) in a proceeding by or in the right of the corporation to procure a judgment in its favor, against expenses (including attorneys’ fees) actually and reasonably incurred by such person or on such person’s behalf in connection with the defense or settlement of such proceeding and any appeal therefrom.

(B) Indemnification in Respect of Successful Defense. To the extent that a present or former director or officer of the corporation has been successful on the merits or otherwise in defense of any proceeding referred to in paragraph (A) of this Section 8.01 or in defense of any claim, issue or matter therein, such person shall be indemnified by the corporation against expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection therewith.

(C) Indemnification in Respect of Proceedings Instituted by Indemnitee. Section 8.01(A) does not require the corporation to indemnify a present or former director or officer of the corporation in respect of a proceeding (or part thereof) instituted by such person on his or her own behalf, unless such proceeding (or part thereof) has been authorized by the Board of Directors or the indemnification requested is pursuant to the last sentence of Section 8.03 of these by-laws.

SECTION 8.02. Advance of Expenses. The corporation shall advance all expenses (including reasonable attorneys’ fees) incurred by a present or former director or officer in defending any proceeding prior to the final disposition of such proceeding upon written request of such person

and delivery of an undertaking (which may be unsecured) by such person to repay such amount if it shall ultimately be determined that such person is not entitled to be indemnified by the corporation. The corporation may authorize any counsel for the corporation to represent (subject to applicable conflict of interest considerations) such present or former director or officer in any proceeding, whether or not the corporation is a party to such proceeding.

SECTION 8.03. Procedure for Indemnification. Any indemnification under Section 8.01 of these by-laws or any advance of expenses under Section 8.02 of these by-laws shall be made only against a written request therefor (together with supporting documentation) submitted by or on behalf of the person seeking indemnification or advance. Indemnification may be sought by a person under Section 8.01 of these by-laws in respect of a proceeding only to the extent that both the liabilities for which indemnification is sought and all portions of the proceeding relevant to the determination of whether the person has satisfied any appropriate standard of conduct have become final. A person seeking indemnification or advance of expenses may seek to enforce such person’s rights to indemnification or advance of expenses (as the case may be) in the Delaware Court of Chancery to the extent all or any portion of a requested indemnification has not been granted within 60 days of, or to the extent all or any portion of a requested advance of expenses has not been granted within 20 days of, the submission of such request. All expenses (including reasonable attorneys’ fees) incurred by such person in connection with successfully establishing such person’s right to indemnification or advance of expenses under this Article, in whole or in part, shall also be indemnified by the corporation.

SECTION 8.04. Burden of Proof.

(A) In any proceeding brought to enforce the right of a person to receive indemnification to which such person is entitled under Section 8.01 of these by-laws, the corporation has the burden of demonstrating that the standard of conduct applicable under the DGCL or other applicable law was not met. A prior determination by the corporation (including its Board of Directors or any committee thereof, its independent legal counsel, or its stockholders) that the claimant has not met such applicable standard of conduct does not itself constitute evidence that the claimant has not met the applicable standard of conduct.

(B) In any proceeding brought to enforce a claim for advances to which a person is entitled under Section 8.02 of these by-laws, the person seeking an advance need only show that he or she has satisfied the requirements expressly set forth in Section 8.02 of these by-laws.

SECTION 8.05. Contract Right; Non-Exclusivity; Survival.

(A) The rights to indemnification and advancement of expenses provided by this Article shall be deemed to be separate contract rights between the corporation and each director and officer who serves in any such capacity at any time while these provisions as well as the relevant provisions of the DGCL are in effect, and no repeal or modification of any of these provisions or any relevant provisions of the DGCL shall adversely affect any right or obligation of such director or officer existing at the time of such repeal or modification with respect to any state of facts then or previously existing or any proceeding previously or thereafter brought or threatened based in whole or in

part upon any such state of facts. Such “contract rights” may not be modified retroactively as to any present or former director or officer without the consent of such director or officer.

(B) The rights to indemnification and advancement of expenses provided by this Article shall not be deemed exclusive of any other indemnification or advancement of expenses to which a present or former director or officer of the corporation seeking indemnification or advancement of expenses may be entitled by any agreement, vote of stockholders or disinterested directors, or otherwise.

(C) The rights to indemnification and advancement of expenses provided by this Article to any present or former director or officer of the corporation shall inure to the benefit of the heirs, executors and administrators of such person.

SECTION 8.06. Insurance. The corporation may purchase and maintain insurance on behalf of any person who is or was or has agreed to become a director or officer of the corporation, or is or was serving at the request of the corporation as a director or officer of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against such person and incurred by such person or on such person’s behalf in any such capacity, or arising out of such person’s status as such, whether or not the corporation would have the power to indemnify such person against such liability under the provisions of this Article.

SECTION 8.07. Employees and Agents. The Board of Directors, or any officer authorized by the Board of Directors generally or in the specific case to make indemnification decisions, may cause the corporation to indemnify any present or former employee or agent of the corporation in such manner and for such liabilities as the Board of Directors may determine, up to the fullest extent permitted by the DGCL and other applicable law.

SECTION 8.08. Interpretation; Severability. Terms defined in Sections 145(h) or (i) of the DGCL have the meanings set forth in such sections when used in this Article. If this Article or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the corporation shall nevertheless indemnify each director or officer of the corporation as to costs, charges and expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement with respect to any action, suit or proceeding, whether civil, criminal, administrative or investigative, including an action by or in the right of the corporation, to the fullest extent permitted by any applicable portion of this Article that shall not have been invalidated and to the fullest extent permitted by applicable law.

ARTICLE IX

General Provisions

SECTION 9.01. Dividends. Dividends upon the capital stock of the corporation, subject to the provisions of the certificate of incorporation, if any, may be declared by the Board of

Directors at any regular or special meeting, pursuant to law. Dividends may be paid in cash, in property, or in shares of the capital stock of the corporation, subject to the provisions of the certificate of incorporation. Before payment of any dividend, there may be set aside out of any funds of the corporation available for dividends such sum or sums as the directors from time to time, in their absolute discretion, think proper as a reserve or reserves to meet contingencies, or for equalizing dividends, or for repairing or maintaining any property of the corporation, or for such other purpose as the directors shall think conducive to the interest of the corporation, and the directors may modify or abolish any such reserve in the manner in which it was created.

SECTION 9.02. Annual Statements. The Board of Directors shall present at each annual meeting, and at any special meeting of the stockholders when called for by vote of the stockholders, a full and clear statement of the business and condition of the corporation.

SECTION 9.03. Contracts. Except as otherwise provided in these by-laws, the Board of Directors may authorize any officer or officers (including the Chairman of the Board if such person is also an officer of the corporation), or any agent or agents, to enter into any contract or to execute or deliver any instrument on behalf of the corporation and such authority may be general or confined to specific instances.

SECTION 9.04. Checks. All checks, notes, bills of exchange or other orders in writing shall be signed by such person or persons as the Board of Directors may from time to time designate.

SECTION 9.05. Corporate Seal. The corporate seal shall have inscribed thereon the name of the corporation, the year of its organization and the words “Corporate Seal, Delaware.” The seal may be used by causing it or a facsimile thereof to be impressed or affixed or reproduced or otherwise.

All funds of the corporation shall be deposited from time to time to the credit of the corporation in such banks, trust companies, or other depositories as the Board of Directors may approve or designate, and all such funds shall be withdrawn only upon checks signed by such one or more officers or employees as the Board of Directors shall from time to time determine.

SECTION 9.07. Corporate Records. Every stockholder shall, upon written demand under oath stating the purpose thereof, have a right to examine, in person or by agent or attorney, during the usual hours for business, for any proper purpose, the stock ledger, books or records of account, and records of the proceedings of the stockholders and directors, and make copies or extracts therefrom. A proper purpose shall mean a purpose reasonably related to such person’s interest as a stockholder. In every instance where an attorney or other agent shall be the person who seeks the right to inspection, the demand under oath shall be accompanied by a power of attorney or such other writing which authorizes the attorney or other agent to so act on behalf of the stockholder. The demand under oath shall be directed to the corporation at its registered office in Delaware or at its principal place of business. Where the stockholder seeks to inspect the books and records of the corporation, other than its ledger or list of stockholders, the stockholder shall first establish (1) compliance with the provisions

of this section respecting the form and manner of making demand for inspection of such document; and (2) that the inspection sought is for a proper purpose. Where the stockholder seeks to inspect the stock ledger or list of stockholders of the corporation and has complied with the provisions of this section respecting the form and manner of making demand for inspection of such documents, the burden of proof shall be upon the corporation to establish that the inspection sought is for an improper purpose.

SECTION 9.08. Electronic Transmission. As used in these by-laws “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 9.09. Amendment of By-Laws. These by-laws may be amended, added to, rescinded or repealed at any meeting of the Board of Directors or of the stockholders, provided that notice of the proposed change was given in the notice of the meeting and, in the case of the Board of Directors, in a notice given no less than twenty-four hours prior to the meeting; provided, however, that in the case of amendments by stockholders, notwithstanding any other provisions of these by-laws or any provision of law which might otherwise permit a lesser vote or no vote, but in addition to any affirmative vote of the holders of any series of preferred stock or any other series or class of stock set forth in the certificate of incorporation which is required by law, the certificate of incorporation or these by-laws, the affirmative vote of the holders of shares representing at least 66 2/3% of the voting power of the then outstanding stock of the corporation entitled to vote generally in the election of directors, present or represented by proxy, voting together as a single class, shall be required to alter, amend or repeal Sections 2.02, 2.07, 2.09, 3.02, 3.03 or this Section 9.09 of these by-laws.

SECTION 9.10. Construction. In the event of any conflict between the provisions of these by-laws as in effect from time to time and the provisions of the certificate of incorporation as in effect from time to time, the provisions of the certificate of incorporation shall be controlling.
