(b) In addition to any other applicable requirements, for business to be properly brought before an annual meeting by a stockholder pursuant to clause (iii) of paragraph (a) of this Section 2.3, the stockholder must have given timely notice thereof in proper written form to the Secretary of the Corporation and such business must be a proper matter for stockholder action under the Delaware General Corporation Law. To be timely, a stockholder’s notice shall be received by the Secretary at the principal executive offices of the Corporation not less than 90 days nor more than 120 days prior to the first anniversary of the date that the Corporation mailed its proxy statement for the preceding year’s annual meeting of stockholders; provided, however, that in the event that the annual meeting is called for a date that is not within 30 days before or after the anniversary of the preceding year’s annual meeting of stockholders, notice by the stockholder to be timely must be so received not later

than the close of business on the 10th day following the day on which such notice of the date of the meeting was mailed or such public announcement of the date of such meeting is first made, whichever first occurs. To be in proper written form, such stockholder’s notice shall set forth: (a) as to each matter that the stockholder proposes to bring before the meeting (i) a brief description of such business and (ii) the reasons for conducting such business at the meeting; and (b) as to the stockholder giving the notice and the beneficial owner, if any, on whose behalf the proposal is made (i) the name and address, as they appear on the Corporation’s books, of such stockholder and of such beneficial owner; (ii) the class and number of shares of capital stock of the Corporation which are beneficially owned by such stockholder and such beneficial owner; (iii) a description of any arrangements or understandings between such stockholder and any other person (including their names) in connection with the proposal of such business by such stockholder and any material interest in such business of such stockholder and such beneficial owner; (iv) a representation that such stockholder intends to appear in person or by proxy at the annual meeting to bring such business before the meeting; and (v) any other information relating to such stockholder and such beneficial owner that would be required to be disclosed in a proxy statement or other filings required to be made in connection with solicitations of proxies for such matters, or may otherwise be required, in each case pursuant to Section 14 of the Securities Exchange Act of 1934 (the “Exchange Act”) and the rules and regulations promulgated thereunder.

(c) Only such business shall be conducted at an annual meeting of stockholders as shall have been brought before the meeting in accordance with the procedures set forth in this Section 2.3. The chairperson of the meeting shall determine whether any business proposed to be transacted by the stockholders has not been properly brought before the meeting and, if he or she should so determine, the chairperson shall declare that such proposed business was not properly brought before the meeting and such business shall not be presented for stockholder action at the meeting.

SECTION 3. NOTICE OF MEETINGS; WAIVER. Written or printed notice, stating the place, date and hour of the meeting and, in case of a special meeting, the purpose or purposes for which the meeting is called, shall be delivered not less than ten (10), nor more than sixty (60), days before the date of the meeting, either personally or by mail, by or at the direction of the President, the Secretary, or the officer or person calling the meeting, to each stockholder of record entitled to vote at such meeting, and to each holder of other securities having voting power. If mailed, such notice shall be deemed to be delivered when deposited in the Unites States mail, postage prepaid, directed to the stockholder or such other security holder at this address as it appears on the records of the Corporation. An affidavit of the Secretary or an Assistant Secretary or of the transfer agent of the corporation that the notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein. A written waiver of any such notice signed by the person entitled thereto, whether before or after the time stated therein, shall be equivalent to the giving of such notice, and neither the business to be transacted at, nor the purpose of, such meeting need be specified in such waiver. Attendance by a stockholder, whether in person or by proxy, at a stockholders’ meeting shall constitute a waiver of notice of such meeting, except where a 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 was not lawfully called or convened.

SECTION 4. FIXING RECORD DATE. For the purpose of determining stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof, or entitled to receive payment of any dividend, or in order to make a determination of stockholders, such date shall not be more than sixty (60) days, and in case of a meeting of stockholders not less than ten (10) days, prior to the date on which the particular action, requiring such determination of stockholders, is to be taken. If no record date is fixed: (a) the record date for the determination of stockholders entitled to notice of or to vote at 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; (b) the record date for determining stockholders for any other purpose shall be at the

close of business on the day on which the Board of Directors adopts the resolution relating thereto. When a determination of stockholders entitled to notice of or to vote at any meeting of stockholders has been made as provided in this Section, such determination shall apply to any adjournment thereof; provided, however, that the Board of Directors may fix a new record date for the adjourned meeting.

SECTION 5. VOTING LIST. The officer of the Corporation who has charge of the stock ledger of the Corporation shall prepare and make, at least ten (10) days before every meeting of stockholders, a complete list of the stockholders entitled to vote at such meeting, arranged in alphabetical order, with the address of and the number of shares held by each. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting, for a period of at least ten (10) days prior to the meeting, either (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. Such list shall also be produced and kept at the time and place of the meeting during the whole time of the meeting and shall be subject to the inspection of any stockholder who is present. The stock ledger shall be the only evidence as to who are the stockholders entitled to examine the stock ledger, the list of stockholders, or the books of the Corporation, or to vote in person or by proxy at any meeting of stockholders.

SECTION 6. QUORUM. The holders of a majority of the shares outstanding and entitled to vote at a meeting, present in person or represented by proxy, shall constitute a quorum at a meeting of stockholders, except as otherwise provided by statute or by the Certificate of Incorporation. The stockholders present at a duly organized meeting may continue to do business until adjournment, notwithstanding the withdrawal of enough of the stockholders to leave less than quorum. If a meeting cannot be organized because a quorum has not attended, the majority of those present or represented by proxy, and entitled to vote at the meeting, may, except as otherwise provided by law, adjourn the meeting to such time and place as they may determine. When a specified item of business requires a vote by a class or series (if the Corporation shall then have outstanding shares of more than one (1) class or series) voting as a class, the holders of a majority of the shares of such class or series shall constitute a quorum (as to such class or series) for the transaction of such item of business.

SECTION 7. VOTING AT MEETINGS.

7.1 VOTING STOCK. Except as otherwise provided by law or by the Certificate of Incorporation, each stockholder shall have one (1) vote for each share of stock entitled to vote and held of record by such stockholder and a proportionate vote for each fractional share so held. Any action which may be taken at a meeting of the stockholders may be taken without a meeting, without prior notice and without a vote, if a consent in writing, setting for 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 present and voted and shall be filed with the Secretary of the Corporation.

7.2 PROXIES. A stockholder, or the holder of any other security having voting power, may vote either in person or by proxy executed in writing by the stockholder, or by his duly authorized attorney-in-fact. No unrevoked proxy shall be voted or acted upon after three (3) years from the date of its execution, 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 so long as, it is coupled with an interest sufficient in law to support an irrevocable power.

7.3 VOTING OF SHARES OWNED BY OTHER CORPORATIONS. Shares standing in the name of another corporation may be voted by such officer, agent or proxy as the By-Laws of such other corporation may prescribe, or in the absence of such provision, as the board of directors of

such other corporation may determine; or, in the absence of such provision or determination, as the President or Vice President and Secretary or Assistant Secretary of such other corporation may be proxy, duly executed and sealed (but not necessarily acknowledged or verified), designate.

7.4 VOTING OF SHARES OWNED BY FIDUCIARIES. Shares held by an administrator, executor, guardian or conservator may be voted by him, either in person or by proxy, without a transfer of such shares into his name. Shares standing in the name of a trustee may be voted by him, either in person or by proxy, but no trustee shall be entitled to vote shares held by him without a transfer of such shares into his name. It shall not be necessary for such fiduciary to obtain a court order authorizing him to vote such shares. The general proxy of a fiduciary shall be given the same weight and effect as the general proxy of an individual or corporation.

7.5 VOTING OF SECURITIES OWNED BY TWO OR MORE PERSONS. If shares or other securities having voting power stand of record in the names of two or more persons, the right to vote such securities and the effect or such vote shall be determined as provide in Section 217 of the Delaware General Corporation Law.

7.6 VOTING OF SHARES OWNED BY RECEIVERS. Shares standing in the name of a receiver may be voted by such receiver without the transfer thereof into his name if authority so to do be contained in an appropriate order of the court by which such receiver was appointed.

7.7 VOTING OF PLEDGED SHARES. A stockholder whose shares are pledged shall be entitled to vote such shares unless in the transfer by the pledger on the books of the Corporation he has expressly empowered the pledgee to vote thereon, in which case only the pledgee, or his proxy, may represent such stock and vote thereon.

7.8. CONDUCT OF BUSINESS. The Board of Directors of the Corporation may adopt by resolution such rules and regulations for the conduct of any meeting of the stockholders as it shall deem appropriate. Except to the extent inconsistent with such rules and regulations as adopted by the Board of Directors, the chairperson and secretary of any meeting of the stockholders shall have the right and authority to prescribe such rules, regulations and procedures and to do all such acts as, in the judgment of such chairperson or secretary, are appropriate for the proper conduct of the meeting. Such rules, regulations or procedures, whether adopted by the Board of Directors or prescribed by the chairperson of the meeting, may include, without limitation, the following: (i) the establishment of an agenda or order of business for the meeting; (ii) the determination of when the polls shall open and close for any given matter or matters to be voted on at the meeting; (iii) rules and procedures for maintaining order at the meeting and the safety of those present; (iv) limitations on attendance at or participation in the meeting to stockholders of record of the Corporation, their duly authorized and constituted proxies or such other persons as the chairperson of the meeting shall determine; (v) restrictions on entry to the meeting after the time fixed for the commencement thereof; and (vi) limitations on the time allotted to questions or comments by participants.

SECTION 8. INSPECTORS OF ELECTION. In advance of any meeting of stockholders, the Board of Directors, by resolution, the Chairman of the Board, the Chief Executive Officer or the President shall appoint one or more inspectors to act at the meeting and make a written report thereof. One or more other persons may be designated as alternate inspectors to replace any inspector who fails to act. If no inspector or alternate is able to act at a meeting of stockholders, the chairperson of the meeting shall appoint one or more inspectors to act at the meeting. Unless otherwise required by applicable law, inspectors may be, among other things, officers, employees or agents of the Corporation. Each inspector, before entering upon the discharge of the duties of inspector, shall take and sign an oath faithfully to execute the duties of inspector with strict impartiality and according to the best of such inspector’s ability.

The inspector shall have the duties prescribed by law and shall take charge of the polls and, when the vote is completed, shall make a certificate of the result of the vote taken and of such other facts as may be required by applicable law.

Any director elected in accordance with the preceding sentence shall hold office for the remainder of the full term of the class of directors in which the new directorship was created or the vacancy occurred and until such director’s successor shall have been elected and qualified.

ARTICLE VII

INDEMNIFICATION OF DIRECTORS, OFFICERS, AGENTS AND EMPLOYEES

SECTION 1. INDEMNIFICATION IN SUITS AND PROCEEDINGS WITH OTHERS. The Corporation shall indemnify to the fullest extent by 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 (other than an action by or in the right of the Corporation) by reason of the fact that he is or was a director, officer, employee or agent of the Corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorney’s fees), judgments, fines and amounts paid in settlement-actually and reasonably incurred by him in connection with such action, suit or proceeding if he acted in good faith and in a manner he 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 conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, 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 he 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 reasonable cause to believe that his conduct was unlawful. The Corporation shall not be obligated to indemnify any director or officer (or his or her heirs, executors or personal or legal representatives) in connection with a proceeding (or part thereof) initiated by such person unless such proceeding (or part thereof) was authorized or consented to by the Board of Directors.

SECTION 2. INDEMNIFICATION IN DERIVATIVE SUITS. The Corporation shall indemnify to the fullest extent by 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 or suit by or in the right of the Corporation to procure a judgment in its favor by reason of the fact that he is or was a director, officer, employee or agent of the Corporation, or is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against

expenses (including attorney’s fees) actually and reasonably incurred by him in connection with the defense or settlement of such action or suit if he acted in good faith and in a manner he 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 for negligence or misconduct in the performance of his duty to the Corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought 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 which the Court of Chancery or such other court shall deem proper.

SECTION 3. REASONABLE DEFENSE EXPENSES. To the extent that a director, officer, employee or agent of the Corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in Sections 1 and 2 of this Article, or in defense of any claim, issue or matter therein, he shall be indemnified against expenses (including attorneys fees) actually and reasonably incurred by him in connection therewith.

SECTION 4. STANDARD OF CONDUCT AND DETERMINATION. Any indemnification under Section 1 and 2 of this Article (unless ordered by a court) shall be made by the Corporation only as authorized in the specific case upon a determination that indemnification of the director, officer, employee or agent is proper in the circumstances because he has met the applicable standard of conduct set forth in Sections 1 and 2 of this Article.

Such determination shall be made (1) by the Board of Directors by a majority vote of a quorum consisting of directors who were not parties to such action, suit or proceeding, or (2) if such quorum is not obtainable, or, even if obtainable a quorum of disinterested directors so directs, by independent legal counsel in a written opinion, or (3) by the stockholders.

SECTION 5. ADVANCE OF DEFENSE EXPENSES. Expenses incurred in defending a civil or criminal action, suit or proceeding may be paid by the Corporation in advance of the final disposition of such action, suit or proceeding as authorized by the Board of Directors in the manner provided in Section 4 of this Article upon receipt of an undertaking by or on behalf of the director, officer, employee or agent to repay such amount unless it shall ultimately be determined that he is entitled to be indemnified by the Corporation as authorized in this Section.

SECTION 6. NONEXCLUSIVITY OF INDEMNIFICATION. The indemnification provided by this Section shall not be deemed exclusive of any other rights to which those indemnified may be entitled under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in his official capacity and as to action in another capacity while holding such office, and shall continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such person.

SECTION 7. INSURANCE AUTHORIZATION. 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 the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against him and incurred by him in any such capacity, or arising out of his status as such, whether or not the Corporation would have the power to indemnify him against such liability under the provisions of this Section.

SECTION 8. DEFINITION OF “CORPORATION” IN MERGERS. For purposes of this Section, references to “the Corporation” shall include, in the case of a merger or consolidation, in addition

to the resulting Corporation, any constituent corporation (including any constituent of a constituent) absorbed in a consolidation or merger which, if its separate existence had continued, would have had power and authority to indemnify its directors, officers and 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 of such constituent corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, shall stand in the same position under the provisions of this Section with respect to the resulting or supervising corporation as he would have with respect to such constituent corporation if its separate existence had continued.

SECTION 9. OTHER DEFINITIONS. For references to “fines” shall include any excise taxes assessed on a person with respect to an employee benefit plan; and references to “serving at the request of the Corporation” purposes of this Section, reference to “other enterprises” shall include employee benefit plans; shall include any service as a director, officer, employee or agent of the Corporation which imposes duties on, or involves services by, such director, officer, employee, or agent with respect to an employee benefit plan, its participants or beneficiaries; and a person who acted in good faith and in a manner he reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner “not opposed to the best interests of the Corporation” as referred to in this Section.
