Except as otherwise provided by applicable law, the Chairman of the meeting shall

have the power and duty to determine whether a nomination or any 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 this Section 3 and, if any proposed nomination or business is not in compliance with this Section 3, to declare that such defective proposal or nomination shall be disregarded.

(iii) Notwithstanding the foregoing provisions of this Section 3., 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 3. Nothing in this Section 3 shall be deemed to affect any rights (A) of Stockholders to request inclusion of proposals in the Corporation’s proxy statement pursuant to Rule 14a-8 under the Exchange Act; or (B) of the holders of any series of Common Stock or Preferred Stock or any outstanding voting indebtedness to elect Directors under specified circumstances.

Notwithstanding any other provisions of the Certificate of Incorporation of the Corporation and notwithstanding that a lesser percentage may be permitted from time to time by applicable law, no provision of this Section 3 of ARTICLE I may be altered, amended or repealed in any respect, nor may any provision inconsistent therewith be adopted, unless such alteration, amendment, repeal or adoption is approved by the affirmative vote of the holders of at least 80 percent of the combined voting power of the then outstanding shares of the Corporation’s stock entitled to vote generally at elections of Directors voting together as a single class, and at least 80 percent of each class, series and issuance of combined voting power of the then outstanding shares of the Corporation’s stock entitled to vote generally at elections of Directors voting separately as a class, series and issuance.

SECTION 4. Quorum. At any meeting of the stockholders, the holders of a majority in number of the total outstanding shares of stock of the Corporation entitled to vote at such meeting, present in person or represented by proxy, shall constitute a quorum of the stockholders for all purposes, unless the representation of a larger number of shares shall be required by law, by the Certificate of Incorporation or by these Bylaws, in which case the representation of the number of shares so required shall constitute a quorum; provided that at any meeting of the stockholders at which the holders of any class of stock of the Corporation shall be entitled to vote separately as a class, the holders of a majority in number of the total outstanding shares of such class, present in person or represented by proxy, shall constitute a quorum for purposes of such class vote unless the representation of a larger number of shares of such class shall be required by law, by the Certificate of Incorporation or by these Bylaws.

SECTION 5. Adjourned Meetings. Whether or not a quorum shall be present in person or represented at any meeting of the stockholders, the holders of a majority in number of the shares of stock of the Corporation present in person or represented by proxy and entitled to vote at such meeting may adjourn from time to time; provided, however, that if the holders of any class of stock of the Corporation are entitled to vote separately as a class upon any matter at such meeting, any adjournment of the meeting in respect of action by such class upon such matter shall be determined by the holders of a majority of the shares of such class present in person or represented by proxy and entitled to vote at such meeting. When a meeting is adjourned to another time or place, notice need not be given of the adjourned meeting if the time and place thereof are announced at the meeting at which the adjournment is taken. At the adjourned meeting the stockholders, or the holders of any class of stock entitled to vote separately as a class, as the case may be, may transact any business which might have been transacted by them at the original meeting. If the adjournment is for more than thirty (30) days, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting. If after the adjournment a new record date for determination of stockholders entitled to vote is fixed for the adjourned meeting, the Board of Directors shall fix as the record date for determining stockholders entitled to notice of such adjourned meeting the same or an earlier date as that fixed for determination of stockholders entitled to vote at the adjourned meeting, and shall give notice of the adjourned meeting to each stockholder of record as of the record date so fixed for notice of such adjourned meeting.

The chairman of each annual and special meeting shall be the Chairman of the Board of Directors, or such person as shall be appointed by the resolution approved by the affirmative vote of a majority of the total number of directors then serving on the Board of Directors.

The Secretary of the Corporation shall act as Secretary of all meetings of the stockholders; but in the absence of the Secretary, the Chairman may appoint any person to act as Secretary of the meeting. It shall be the duty of the Secretary to prepare and make, at least ten (10) days before every meeting of stockholders, a complete list of stockholders entitled to vote at such meeting (provided, however, if the record date for determining the stockholders entitled to vote is less than ten (10) days before the date of the meeting, the list shall reflect the stockholders entitled to vote as of the tenth day before the meeting date), arranged in alphabetical order and 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 at least ten (10) days prior to the meeting (i) on a reasonably accessible electronic network, provided that the information required to gain access to such list is provided with the notice of meeting or (ii) during ordinary business hours at the principal place of business of the corporation. If the meeting is to be held at a place, then a list of stockholders entitled to vote at the meeting shall be produced and kept at the time and place of the meeting during the whole time thereof and may be examined by any stockholder

who is present. If the meeting is to be held solely by means of remote communication, then the list shall also be open to the examination of any stockholder during the whole time of the meeting on a reasonably accessible electronic network, and the information required to access such list shall be provided with the notice of the meeting.

SECTION 7. Voting; Proxies. Except as otherwise provided in the Certificate of Incorporation or by law, each stockholder shall be entitled to one vote for each share of the capital stock of the Corporation registered in the name of such stockholder upon the books of the Corporation. 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 him 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. When directed by the presiding officer or upon the demand of any stockholder, the vote upon any matter before a meeting of stockholders shall be by ballot. Except as otherwise provided by law, by the Certificate of Incorporation, or by the rules or regulations of any stock exchange applicable to the Corporation, Directors shall be elected by a plurality of the votes cast at a meeting of stockholders by the stockholders entitled to vote in the election and, whenever any corporate action, other than the election of Directors is to be taken, it shall be authorized by a majority of the votes cast at a meeting of stockholders by the stockholders entitled to vote thereon.

Shares of the capital stock of the Corporation belonging 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.

SECTION 8. Inspectors. When required by law or directed by the presiding officer or upon the demand of any stockholder entitled to vote, but not otherwise, the polls shall be opened and closed, the proxies and ballots shall be received and taken in charge, and all questions touching the qualification of voters, the validity of proxies and the acceptance or rejection of votes shall be decided at any meeting of the stockholders by two or more Inspectors who may be appointed by the Board of Directors before the meeting, or if not so appointed, shall be appointed by the presiding officer at the meeting.

ARTICLE V

Indemnification of Directors and Officers

SECTION 1. Nature of Indemnity. The Corporation shall indemnify 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, by reason of the fact that he is or was or has agreed to become a Director or officer of the Corporation, or is or was serving or has agreed to serve at the request of the Corporation as a Director or officer of another corporation, partnership, joint venture, trust or other enterprise, or by reason of any action alleged to have been taken or omitted in such capacity, and may indemnify any person who was or is a party or is threatened to be made a party to such an action, suit or proceeding by reason of the fact that he is or was or has agreed to become an employee or agent of the Corporation, or is or was serving or has agreed to serve at the request of the Corporation as an employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him or on his behalf in connection with such action, suit or proceeding and any appeal therefrom, 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; except that in the case of an action or suit by or in the right of the Corporation to procure a judgment in its favor (1) such indemnification shall be limited to expenses (including attorneys’ fees) actually and reasonably incurred by such person in the defense or settlement of such action or suit, (2) 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 Delaware 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 Delaware Court of Chancery or such other court shall deem proper, and (3) the Corporation shall not be required to indemnify any person in connection with a proceeding initiated by such person unless the proceeding was authorized in the specific case by the Board of Directors.

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.

SECTION 2. Successful Defense. To the extent that a Director or officer has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in Section 1 of this Article V 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 3. Determination that Indemnification is Proper. Any indemnification of a Director or Officer of the Corporation under Section 1 of this Article V (unless ordered by a court) shall be made by the Corporation unless a determination is made that indemnification of the Director or officer is not proper in the circumstances because he has not met the applicable standard of conduct set forth in Section 1. Any indemnification of an employee or agent of the Corporation under Section 1 (unless ordered by a court) may be made by the Corporation upon a determination that indemnification of the employee or agent is proper in the circumstances because he has met the applicable standard of conduct set forth in Section 1. Any 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 a 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 4. Advance Payment of Expenses. Unless the Board of Directors otherwise determines in a specific case, expenses incurred by a Director or officer in defending a civil or criminal 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 by or on behalf of the Director or officer to repay such amount if it shall ultimately be determined that he is not entitled to be indemnified by the Corporation as authorized in this Article V. Such expenses incurred by other employees and agents may be so paid upon such terms and conditions, if any, as the Board of Directors deems appropriate. The Board of Directors may authorize the Corporation’s legal counsel to represent such Director, officer, employee or agent in any action, suit or proceeding, whether or not the Corporation is a party to such action, suit or proceeding.

SECTION 5. Insurance, Contracts and Funding. The Corporation may maintain insurance, at its expense, to protect itself and any Director, officer, employee or agent of the Corporation or another corporation, partnership, joint venture, trust or other enterprise against any expense, liability or loss, whether or not the Corporation would have the power to indemnify such person against such expense, liability or loss under the General Corporation Law of the State of Delaware. The Corporation may enter into contracts with any indemnitee in furtherance of the provisions of this Article V and may create a trust fund, grant a security interest or use other means (including, without limitation, a letter of credit) to ensure the payment of such amounts as may be necessary to effect indemnification as provided in this Article V.

SECTION 6. Survival: Preservation of Other Rights. The foregoing indemnification provisions shall be deemed to be a contract between the Corporation and each Director, officer, employee and agent who serves in any such capacity at any time while these provisions as well as the relevant provisions of the Delaware General Corporation Law are in effect and any repeal or modification thereof shall not affect any right or obligation then existing with respect to any state of facts then or previously existing or any action, suit, or proceeding previously or thereafter brought or threatened based in whole or in part upon any such state of facts. Such a contract right may not be modified retroactively without the consent of such Director, officer, employee or agent.

The indemnification provided by this Article V 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 a person. The Corporation may enter into an agreement with any of its Directors, officers, employees or agents providing for indemnification and advancement of expenses, including attorneys fees that may change, enhance, qualify or limit any right to indemnification or advancement of expenses created by this Article V.

SECTION 6. Severability. If this Article V 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 and may indemnify each employee or agent of the Corporation as to costs, charges and expenses (including attorneys’ fees), judgment, 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 V that shall not have been invalidated and to the fullest extent permitted by applicable law.

SECTION 7. Subrogation. In the event of payment of indemnification to a person described in Section 1 of this Article V, the Corporation shall be subrogated to the extent of such payment to any right of recovery such person may have and such person, as a condition of receiving indemnification from the Corporation, shall execute all documents and do all things that the Corporation may deem necessary or desirable to perfect such right of recovery, including the execution of such documents necessary to enable the Corporation effectively to enforce any such recovery.

SECTION 8. No Duplication of Payments. The Corporation shall not be liable under this Article V to make any payment in connection with any claim made against a person described in Section 1 of this Article V to the extent such person has otherwise received payment (under any insurance policy, bylaw or otherwise) of the amounts otherwise indemnifiable hereunder.

ARTICLE VI

Stock-Seal-Fiscal Year

SECTION 1. Certificates for Shares of Stock. The certificates for shares of stock of the Corporation shall be in such form, not inconsistent with the Certificate of Incorporation, as shall be approved by the Board of Directors. Every holder of stock represented by certificates shall be entitled to have a certificate signed by or in the name of the Corporation by the Chairman of the Board of Directors or the President or a Vice President, and by the Treasurer or an Assistant Treasurer, or the Secretary or an Assistant Secretary, of the Corporation certifying the number of shares owned by such holder in the Corporation. Some or all of the issuances of shares of stock of the Corporation may be issued as uncertificated shares.

In case any officer or officers who shall have signed any such certificate or certificates shall cease to be such officer or officers of the Corporation, whether because of death, resignation or otherwise, before such certificate or certificates shall have been delivered by the Corporation, such certificate or certificates may nevertheless be issued and delivered as though the person or persons who signed such certificate or certificates had not ceased to be such officer or officers of the Corporation.

All certificates for shares of stock shall be consecutively numbered as the same are issued. The name of the person owning the shares represented thereby with the number of such shares and the date of issue thereof shall be entered on the books of the Corporation.

Except as hereinafter provided, all certificates surrendered to the Corporation for transfer shall be canceled, and no new certificates shall be issued until former certificates for the same number of shares have been surrendered and canceled.

SECTION 2. Lost, Stolen or Destroyed Certificates. Whenever a person owning a certificate for shares of stock of the Corporation alleges that it has been lost, stolen or destroyed, he shall file in the office of the Corporation an affidavit setting forth, to the best of his knowledge and belief, the time, place and circumstances of the loss, theft or destruction, and, if required by the Board of Directors, a bond of indemnity or other indemnification sufficient in the opinion of the Board of Directors to indemnify the Corporation and its agents against any claim that may be made against it or them on account of the alleged loss, theft or destruction of any such certificate or the issuance of a new certificate in replacement therefor. Thereupon the Corporation may cause to be issued to such person a new certificate in replacement for the certificate alleged to have been lost, stolen or destroyed. Upon the stub of every new certificate so issued shall be noted the fact of such issue and the number, date and the name of the registered owner of the lost, stolen or destroyed certificate in lieu of which the new certificate is issued.

SECTION 3. Transfer of Shares. Shares of stock of the Corporation shall be transferred on the books of the Corporation by the holder thereof, in person or by his attorney duly authorized in writing, upon surrender and cancellation of certificates for the number of shares of stock to be transferred, except as provided in Section 2 of this Article VI.

SECTION 4. Regulations. The Board of Directors shall have power and authority to make such rules and regulations as it may deem expedient concerning the issue, transfer and registration of certificates for shares of stock of the Corporation.

SECTION 5. Record Date. In order that the Corporation may determine the stockholders entitled to notice of 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, unless otherwise required by law, not be more than sixty (60) nor less than ten (10) days before the date of such meeting. If the Board of Directors so fixes a date, such date shall also be the record date for determining the stockholders entitled to vote at such meeting unless the Board of Directors determines, at the time it fixes such record date, that a later date

on or before the date of the meeting shall be the date for making such determination. If no record date is fixed by the Board of Directors, 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 determination of stockholders entitled to vote at the adjourned meeting, and in such case shall also fix as the record date for stockholders entitled to notice of such adjourned meeting the same or an earlier date as that fixed for determination of stockholders entitled to vote in accordance herewith at the adjourned meeting.

(b) 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 shall not be more than sixty (60) days prior to such other action. If no such record date is fixed, the record date for determining stockholders for any such purpose shall be at the close of business on the day on which the Board of Directors adopts the resolution relating thereto.

SECTION 6. Dividends. Subject to the provisions of the Certificate of Incorporation, the Board of Directors shall have power to declare and pay dividends upon shares of stock of the Corporation, but only out of funds available for the payment of dividends as provided by law.

Subject to the provisions of the Certificate of Incorporation, any dividends declared upon the stock of the Corporation shall be payable on such date or dates as the Board of Directors shall determine. If the date fixed for the payment of any dividend shall in any year fall upon a legal holiday, then the dividend payable on such date shall be paid on the next day not a legal holiday.

SECTION 7. Corporate Seal. The Board of Directors shall provide a suitable seal, containing the name of the Corporation, which seal shall be kept in the custody of the Secretary. A duplicate of the seal may be kept and be used by any officer of the Corporation designated by the Board of Directors, the Chairman of the Board, the Chief Executive Officer, the President, the Chief Operating Officer, or the Chief Financial Officer.

SECTION 8. Fiscal Year. The fiscal year of the Corporation shall be such fiscal year as the Board of Directors from time to time by resolution shall determine.
