     (C)  General . (1) Only such persons who are nominated in accordance with the procedures set forth in this Section 2.03 shall be eligible for election to serve as directors and only such other 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. Except as otherwise provided by law, the Certificate of Incorporation or these By-laws, the Chairman of the Board shall have the power and duty to determine whether a nomination or any other business proposed to be brought before the meeting was made or proposed, as the case may be, in accordance with the procedures set forth in these By-laws (including whether the stockholder or beneficial owner, if any, on whose behalf the nomination is made or other business is being proposed solicited (or is part of a group which solicited) or did not so solicit, as the case may be, proxies in support of such stockholder’s nominee or other business in compliance with such stockholder’s representation as required by clause (d)(iv) of paragraph A(3) of this Section 2.03). If any proposed nomination or other business is not in compliance with these By-laws, the chairman of the meeting of stockholders shall have the power and duty to declare to the meeting that any such nomination or other business was not properly brought before the meeting and in accordance with the provisions of these By-laws, and that such nomination or other business not properly brought before the meeting shall not be transacted. Notwithstanding the foregoing provisions of this Section 2.03, unless otherwise required by law, if the stockholder does not provide the information required under clauses (c)(ii) and (d)(i)-(iii) of paragraph A(3) of this Section 2.03 to the Corporation within five (5) business days following the record date for an annual or special meeting of stockholders of the Corporation or if the stockholder (or a qualified representative of the stockholder) does not appear at the annual or special meeting to present a nomination or other business, such nomination shall be disregarded and such other business shall not be transacted, notwithstanding that proxies in respect of such vote may have been received by the Corporation. For purposes of this Section 2.03, to be considered a qualified representative of the stockholder, a person must be authorized by a writing executed by such stockholder or an electronic transmission delivered by such stockholder to act for such stockholder as proxy at the meeting of stockholders and such person must produce such writing or electronic transmission, or a reliable reproduction of the writing or electronic transmission, at the meeting of stockholders.

     (2) Whenever used in these By-laws, “public announcement” shall mean disclosure: (a) in a press release released by the Corporation, provided such press release is released by the Corporation following its customary procedures, as reported by the Dow Jones News Service, Associated Press or a comparable national news service, or is generally available on internet news sites, or (b) in a document publicly filed by the Corporation with the Securities and Exchange Commission pursuant to Sections 13, 14 or 15(d) of the Exchange Act.

     (3) Nothing in these By-laws shall be deemed to affect any rights of the holders of any class or series of stock having a preference over the Common Stock as to dividends or upon liquidation to elect directors under specified circumstances.

such meeting, and, in the case of a special meeting, the purposes for which the meeting is called, shall be mailed to or transmitted electronically by the Secretary of the Corporation to each stockholder of record entitled to vote thereat. Unless otherwise provided by law, the certificate of incorporation or these by-laws, the notice of any meeting shall be given not less than ten (10) nor more than sixty (60) days before the date of the meeting to each stockholder entitled to vote at such meeting.

Unless otherwise required by law or the Certificate of Incorporation, the holders of a majority of the voting power of the outstanding shares of stock entitled to vote thereat, present in person or represented by proxy, shall constitute a quorum for the transaction of business at all meetings of stockholders. When a quorum is once present to organize a meeting, the quorum is not broken by the subsequent withdrawal of any stockholders.

     Section 2.06. Voting . At all meetings of the stockholders, each stockholder shall be entitled to vote, in person or by proxy, the shares of voting stock owned by such stockholder of record on the record date for the meeting. When a quorum is present or represented at any meeting, the vote of the holders of a majority of the voting power of the shares of stock present in person or represented by proxy and entitled to vote thereon shall decide any question brought before such meeting, unless the question is one upon which, by express provision of law, the rules or regulations of any stock exchange applicable to the Corporation, or applicable law or pursuant to any regulation applicable to the Corporation or its securities, of the Certificate of Incorporation or of these By-laws, a different vote is required, in which case such express provision shall govern and control the decision of such question. Notwithstanding the foregoing sentence, at each meeting of the stockholders for the election of directors at which a quorum is present, each director shall be elected by the vote of the majority of the votes cast; provided, that if as of a date that is ten (10) days in advance of the date the corporation 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, the directors, not exceeding the authorized number of directors as fixed by the Board of Directors in accordance with the Certificate of Incorporation, shall be elected by a plurality of the shares represented in person or by proxy at any such meeting and entitled to vote on the election of directors. For purposes of this Section, a majority of the votes cast means that the number of shares voted ‘for’ a director must exceed the number of shares voted ‘against’ that director. If, for any cause, the Board of Directors shall not have been elected at an annual meeting, they may be elected as soon thereafter as convenient at a special meeting of the stockholders called for that purpose in the manner provided in these By-laws.

A telegram, cablegram or other electronic transmission consenting to an action to be taken and transmitted by a stockholder or proxyholder, or by a person or persons authorized to act for a stockholder or

proxyholder, shall be deemed to be written, signed and dated for the purposes of this Section 2.09 to the extent permitted by law. Any such consent shall be delivered in accordance with Section 228(d)(1) of the DGCL. 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 or electronic transmission and who, if the action had been taken at a meeting, would have been entitled to notice of the meeting if the record date of such meeting had been the date that written consents signed by a sufficient number of stockholders or members to take the action were delivered to the Corporation as provided by law.

Any business may be transacted at the adjourned meeting that might have been transacted at the meeting originally noticed. If the adjournment is for more than thirty (30) days, or if after the adjournment a new record date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting.

     Section 2.11. Remote Communication .

If no record date is fixed: (x) 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; (y) the record date for determining stockholders entitled to express consent to corporate action in writing without a meeting, when no prior action of the Board of Directors is required by law, shall be the first date on which a signed written consent setting forth the action taken or proposed to be taken is delivered to the corporation in accordance with applicable law, or, if prior action by the Board of Directors is required by law, shall be at the close of business on the day on which the Board of Directors adopts the resolution taking such prior action; and (z) 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.

     Section 5.05. Registered Stockholders . Prior to the surrender to the Corporation of the certificate or certificates for a share or shares of stock with a request to record the transfer of such share or shares, the Corporation may treat the registered owner as the person entitled to receive dividends, to vote, to receive notifications, and otherwise to exercise all the rights and powers of an owner. To the fullest extent permitted by law, the Corporation shall not be bound to recognize any equitable or other claim to or interest in such share or shares on the part of any other person, whether or not it shall have express or other notice thereof.

ARTICLE VI

NOTICE AND WAIVER OF NOTICE

     Section 6.01. Notice . If mailed, notice to stockholders shall be deemed given when deposited in the mail, postage prepaid, directed to the stockholder at such stockholder’s address as it appears on the records of the Corporation. Without limiting the manner by which notice otherwise may be given effectively to stockholders, any notice to stockholders may be given by electronic transmission in the manner provided in Section 232 of the DGCL.

     Section 6.02. Waiver of Notice . A written waiver of any notice, signed by a stockholder or director, or waiver by electronic transmission by such person, whether given before or after the time of the event for which notice is to be given, shall be deemed equivalent to the notice required to be given to such person. Neither the business nor the purpose of any meeting need be specified in such a waiver. Attendance at any meeting (in person or by remote communication) shall constitute waiver of notice except attendance 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.

ARTICLE VII

INDEMNIFICATION

     Section 7.01. Indemnification Respecting Third Party Claims.

     (A)  Indemnification of Directors and Officers . The Corporation, to the fullest extent permitted and in the manner required, by the laws of the State of Delaware as in effect from time to time shall indemnify in accordance with the following provisions of this Article any person who was or is made a party to or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding (including any appeal thereof), whether civil, criminal, administrative, regulatory or investigative in nature (other than an action by or in the right of the Corporation), by reason of the fact that such person is or was a director or officer of the Corporation, or, if at a time when he or she was a director or officer of the Corporation, is or was serving at the request of, or to represent the interests of, the Corporation as a director, officer, partner, member, trustee, fiduciary, employee or agent (a “Subsidiary Officer”) of another corporation, partnership, joint venture, limited liability company, trust, employee benefit plan or other enterprise including any charitable or not-for-profit public service organization or trade association (an “Affiliated Entity”), against expenses (including attorneys’ fees and disbursements), costs, judgments, fines, penalties and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful; provided, however, that the Corporation shall not be obligated to indemnify against any amount paid in settlement unless the Corporation has consented to such settlement. The termination of any action, suit or proceeding by judgment, order, settlement or conviction or upon a plea of nolo contendere or its equivalent shall not, of itself, create a presumption that the person did not act in good faith and in a manner which such person reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action or proceeding, that such person had reasonable cause to believe that his or her conduct was unlawful. Notwithstanding anything to the contrary in the foregoing provisions of this paragraph, a person shall not be entitled, as a matter of right, to indemnification pursuant to this paragraph against costs or expenses incurred in connection with any action, suit or proceeding commenced by such person against the Corporation or any Affiliated Entity or any person who is or was a director, officer, partner, member, fiduciary, employee or agent of the Corporation or a Subsidiary Officer of any Affiliated Entity in their capacity as such, but such indemnification may be provided by the Corporation in a specific case as permitted by Section 7.06 of this Article.

     (B)  Indemnification of Employees and Agents . The Corporation may indemnify any employee or agent of the Corporation in the manner and to the same or a lesser extent that it shall indemnify any director or officer under paragraph (A) above in this Section 7.01.

     Section 7.02. Indemnification Respecting Derivative Claims.

     (A)  Indemnification of Directors and Officers . The Corporation, to the fullest extent permitted and in the manner required, by the laws of the State of Delaware as in effect from time to time shall indemnify, in accordance with the following provisions of this Article, any person who was or is made a party to or is threatened to be made a party to any threatened, pending or completed action or suit (including any appeal thereof) brought by or in the right of the Corporation to procure a judgment in its favor by reason of the fact that such person is or was a director or officer of the Corporation, or, if at a time when he or she was a director or officer of the Corporation, is or was serving at the request of, or to represent the interests of, the Corporation as a Subsidiary Officer of an Affiliated Entity against expenses (including attorneys’ fees and disbursements) and costs actually and reasonably incurred by such person in connection with such action or suit if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Corporation, except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the Corporation unless, and only to the extent that, the Court of Chancery of the State of Delaware or the court in which such judgment was rendered shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses and costs as the Court of Chancery of the State of Delaware or such other court shall deem proper. Notwithstanding anything to the contrary in the foregoing provisions of this paragraph, a person shall not be entitled, as a matter of right, to indemnification pursuant to this paragraph against costs and expenses incurred in connection with any action or suit in the right of the Corporation commenced by such Person, but such indemnification may be provided by the Corporation in any specific case as permitted by Section 7.06 of this Article.

     (B)  Indemnification of Employees and Agents . The Corporation may indemnify any employee or agent of the Corporation in the manner and to the same or a lesser extent that it shall indemnify any director or officer under paragraph (A) above in this Section 7.02.

     Section 7.03. Determination of Entitlement to Indemnification . Any indemnification to be provided under Section 7.01 or 7.02 of this Article (unless ordered by a court of competent jurisdiction) shall be made by the Corporation only as authorized in the specific case upon a determination that indemnification is proper under the circumstances because such person has met the applicable standard of conduct set forth in such paragraph. Such determination shall be made in accordance with any applicable procedures authorized by the Board of Directors and in accordance with the DGCL. In the event a request for indemnification is made by any person referred to in paragraph (a) of Section 7.01 or 7.02 of this Article, the Corporation shall use its best efforts to cause such determination to be made not later than 90 days after such request is made.

     Section 7.04. Right to Indemnification in Certain Circumstances.

     (A)  Indemnification of Successful Party . Notwithstanding the other provisions of this Article, to the extent that a director or officer of the Corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in any of paragraphs (A) or (B) of Section 7.01 or 7.02 of this Article, in defense of any claim, issue or matter therein, or in any action, suit or proceeding brought by the director or officer to enforce rights to indemnification or advancement of expenses and costs granted pursuant to this Article, such person shall be indemnified against expenses (including attorneys’ fees and disbursements) and costs actually and reasonably incurred by such person in connection therewith.

To the extent any person who is or was a director or officer of the Corporation has served or prepared to serve as a witness in any action, suit or proceeding (whether civil, criminal, administrative, regulatory or investigative in nature), including any investigation by any legislative body or any regulatory or self-regulatory body by which the Corporation’s business is regulated, by reason of his or her services as a director or officer of the Corporation or his or her service as a Subsidiary Officer of an Affiliated Entity at a time when he or she was a director or officer of the Corporation (assuming such person is or was serving at the request of, or to represent the interests of, the Corporation as a Subsidiary Officer of such Affiliated Entity) but excluding service as a witness in an action or suit commenced by such person (unless such expenses were incurred with the approval of the Board of Directors, a committee thereof or the Chairman, a Vice Chairman or the Chief Executive Officer of the Corporation), the Corporation shall indemnify such person against out-of-pocket costs and expenses (including attorneys’ fees and disbursements) actually and reasonably incurred by such person in

connection therewith and shall use its best efforts to provide such indemnity within 45 days after receipt by the Corporation from such person of a statement requesting such indemnification, averring such service and reasonably evidencing such expenses and costs; it being understood, however, that the Corporation shall have no obligation under this Article to compensate such person for such person’s time or efforts so expended. The Corporation may indemnify any employee or agent of the Corporation to the same or a lesser extent as it may indemnify any director or officer of the Corporation pursuant to the foregoing sentence of this paragraph.

     Section 7.05. Advances of Expenses.

     (A)  Advances to Directors and Officers . To the fullest extent not prohibited by applicable law, expenses and costs, incurred by any person referred to in paragraph (a) of Section 7.01 or 7.02 of this Article in defending a civil, criminal, administrative, regulatory or investigative action, suit or proceeding shall be paid by the Corporation in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking in writing by or on behalf of such person to repay such amount if it shall ultimately be determined that such person is not entitled to be indemnified in respect of such costs and expenses by the Corporation as authorized by this Article.

     Section 7.06. Indemnification Not Exclusive . The provision of indemnification to or the advancement of expenses and costs to any person under this Article, or the entitlement of any person to indemnification or advancement of expenses and costs under this Article, shall not limit or restrict in any way the power of the Corporation to indemnify or advance expenses and costs to such person in any other way permitted by law or be deemed exclusive of, or invalidate, any right to which any person seeking indemnification or advancement of expenses and costs may be entitled under any law, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in such person’s capacity as an officer, director, employee or agent of the Corporation and as to action in any other capacity.

     Section 7.07. Corporate Obligations; Reliance . The rights granted pursuant to this Article shall vest at the time a person becomes a director or officer of the Corporation and shall be deemed to create a binding contractual obligation on the part of the Corporation to directors and officers of the Corporation, and such persons in acting in their capacities as officers or directors of the Corporation or Subsidiary Officers of any Affiliated Entity shall be entitled to rely on such provisions of this Article, without giving notice thereof to the Corporation.

     Section 7.08. Accrual of Claims; Successors . The indemnification and advancement of expenses and costs provided or permitted under the foregoing provisions of this Article shall or may, as the case may be, apply in respect of any expense, cost, judgment, fine, penalty or amount paid in settlement, whether or not the claim or cause of action in respect thereof accrued or arose before or after the effective date of such provisions of this Article.

Any repeal or modification of the provisions of this Article shall be prospective only and shall not adversely affect the rights of any person who is or was a director, officer, employee or agent of the Corporation hereunder at the time of any act or omission occurring prior to such repeal or modification.

     Section 7.09. Insurance . The Corporation may purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the Corporation, or is or was serving at the request of, or to represent the interests of, the Corporation as a Subsidiary Officer of any Affiliated Entity, against any liability asserted against such person and incurred by such person 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 or applicable law.

     Section 7.10. Definitions of Certain Terms . For purposes of this Article: (i) references to “the Corporation” shall include, in addition to the resulting corporation, any constituent corporation (including any constituent of a constituent) absorbed into the Corporation in a consolidation or merger if such corporation would have been permitted (if its corporate existence had continued) under applicable law to indemnify its directors, officers, employees or agents, so that any person who is or was a director, officer, employee or agent of such constituent corporation, or is or was serving at the request, or to represent the interests of, such constituent corporation as a director, officer, employee or agent of any Affiliated Entity shall stand in the same position under the provisions of this Article with respect to the resulting or surviving corporation as such person would have with respect to such constituent corporation if its separate existence had continued; (ii) references to “fines” shall include any excise taxes assessed on a person with respect to an employee benefit plan; (iii) references to “serving at the request of the Corporation” shall include any service as a director, officer, partner, member, trustee, fiduciary, employee or agent of the Corporation or any Affiliated Entity which service imposes duties on, or involves services by, such director, officer, partner, member, trustee, fiduciary, employee or agent with respect to an employee benefit plan, its participants, or beneficiaries; and (iv) a person who acted in good faith and in a manner such person reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner “not opposed to the best interest of the Corporation” as referred to in this Article.
