Except as otherwise provided in the Certificate of Incorporation, a special meeting of the stockholders of the Corporation may be called at any time by the Board of Directors, the Chairman of the Board or the President and shall be called by the Chairman of the Board, the President or the Secretary at the request in writing of stockholders holding together at least fifty percent (50%) of the number of shares of stock outstanding and entitled to vote at such meeting.

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 the 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.

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.

Such list shall be open, 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, for the ten (10) days next preceding the meeting, to the examination of any stockholder, for any purpose germane to the meeting, during ordinary business hours, and shall be produced and kept at the time and place of the meeting during the whole time thereof and subject to the inspection of any stockholder who may be present.

If any person so appointed fails to appear or act, the vacancy may be filled by appointment in like manner.

SECTION 9. Consent of Stockholders in Lieu of Meeting. Unless otherwise provided in the Certificate of Incorporation, any action required to be taken or which may be taken at any annual or special meeting of the stockholders of the Corporation, may be taken without a meeting, without prior notice and without a vote, if a consent in writing, setting forth the action so taken, shall be signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted.

SECTION 11. Advance Notice Provisions for Business to be Transacted at Annual Meeting. No business may be transacted at an annual meeting of stockholders, other than business that is either (a) specified in the notice of meeting (or any supplement thereto) given by or at the direction of the Board of Directors (or any duly authorized committee thereof), (b) otherwise properly brought before the annual meeting by or at the direction of the Board of

Board of Directors

SECTION 1.

(a) Number and Term of Office. The business and affairs of the Corporation shall be managed by or under the direction of not less than five (5) nor more than eleven (11) Directors, the exact number of which shall be fixed from time to time by the affirmative vote of a majority of the Board of Directors, who need not be stockholders of the Corporation.

The Directors shall, except as hereinafter otherwise provide for filling vacancies, be elected at the annual meeting of stockholders, and shall hold office until their respective successors are elected and qualified or until their earlier resignation or removal. The number of Directors may be altered from time to time by amendment of these Bylaws.

(b) Procedure for Stockholder Election of Directors; Required Vote. At any meeting of the stockholders for the election of directors at which a quorum is present, each director shall be elected by the affirmative vote of a majority of the votes cast with respect to the director, provided that if the number of nominees exceeds the number of directors to be elected, directors shall be elected by the affirmative vote of a plurality of the votes cast. For purposes of this Section 1(b), votes cast shall include votes for, against or to withhold authority for a director. An abstention or broker non-vote shall not count as a vote cast with respect to a director. If an incumbent director fails to be reelected by a majority vote when such a vote is required and offers to resign, and if that resignation is not accepted by the Board of Directors, such director shall continue to serve until the next annual meeting and until his or her successor is duly elected, or his or her earlier resignation or removal. If a director’s resignation is accepted by the Board of Directors or if a nominee for director is not elected and the nominee is not an incumbent director, then the Board of Directors, in its sole discretion, may fill any resulting vacancy pursuant to the provisions of Article II, Section 2 of these Bylaws or may decrease the size of the Board of Directors pursuant to the provisions of Article II, Section 1(a) of these Bylaws.

SECTION 2. Removal, Vacancies and Additional Directors. The stockholders may, at any special meeting the notice of which shall state that it is called for that purpose, remove, with or without cause, any Director and fill the vacancy; provided that whenever any Director shall have been elected by the holders of any class of stock of the Corporation voting separately as a class under the provisions of the Certificate of Incorporation, such Director may be removed and the vacancy filled only by the holders of that class of stock voting separately as a class. Vacancies caused by any such removal and not filled by the stockholders at the meeting at which such removal shall have been made, or any vacancy caused by the death or resignation of any Director or for any other reason, and any newly created directorship resulting from any increase in the authorized number of Directors, may be filled by the affirmative vote of a majority of the Directors then in office, although less than a quorum, and any Director so elected to fill any such vacancy or newly created directorship shall hold office until his successor is elected and qualified or until his earlier resignation or removal.

When one or more Directors shall resign effective at a future date, a majority of the Directors then in office, including those who have so resigned, shall have power to fill such vacancy or vacancies, the vote thereon to take effect when such resignation or resignations shall become effective, and each Director so chosen shall hold office as herein provided in connection with the filling of other vacancies.

Unless otherwise indicated in the notice thereof, any and all business other than an amendment of these Bylaws may be transacted at any special meeting, and an amendment of these Bylaws may be acted upon if the notice of the meeting shall have stated that the amendment of these Bylaws is one of the purposes of the meeting. At any meeting at which every Director shall be present, even though without any notice, any business may be transacted, including the amendment of these Bylaws.

SECTION 6. Quorum. Subject to the provisions of Section 2 of this Article II, a majority of the members of the Board of Directors in office (but in no case less than one-third of the total number of Directors nor less than two Directors) shall constitute a quorum for the transaction of business and the vote of the majority of the Directors present at any meeting of the Board of Directors at which a quorum is present shall be the act of the Board of Directors. If at any meeting of the Board there is less than a quorum present, a majority of those present may adjourn the meeting from time to time.

SECTION 7. Organization. The Chairman of the Board or, in his absence, the President shall preside at all meetings of the Board of Directors.

Any such committee, to the extent provided by resolution passed by a majority of the whole Board, shall have and may exercise all the powers and authority of the Board of Directors in the management of the business and the affairs of the Corporation, and may authorize the seal of the Corporation to be affixed to all papers which may require it; but no such committee shall have the power or authority in reference to amending the Certificate of Incorporation, adopting an agreement of merger or consolidation, recommending to the stockholders the sale, lease or exchange of all or substantially all of the Corporation’s property and assets, recommending to the stockholders a dissolution of the Corporation or the revocation of a dissolution, or amending these Bylaws; and unless such resolution, these Bylaws, or the Certificate of Incorporation expressly so provide, no such committee shall have the power or authority to declare a dividend or to authorize the issuance of stock.
