ARTICLE V NO PREEMPTIVE RIGHTS No holder of any stock of the corporation shall have any preemptive right to purchase, subscribe for, or otherwise acquire any shares of stock of the corporation of any class now or hereafter authorized, or any securities exchangeable for or convertible into such shares. ARTICLE VI EXISTENCE The corporation shall have perpetual existence. ARTICLE VII BOARD OF DIRECTORS; BYLAWS All the powers of the corporation, insofar as the same may be lawfully vested by these Articles of Incorporation in the Board of Directors, are hereby conferred upon the Board of Directors. In furtherance and not in limitation of that power, the Board of Directors shall have the power to make, adopt, alter, amend and repeal from time to time the Bylaws of the corporation, subject to the right of the shareholders entitled to vote with respect thereto to adopt, alter, amend and repeal Bylaws made by the Board of Directors, or to make new Bylaws; provided, however, that the Bylaws shall not be adopted, altered, amended or repealed, or new Bylaws made, by the shareholders of the corporation except by the affirmative vote of the holders of at least two-thirds (2/3) of the votes entitled to be cast thereon at any annual or special meeting of shareholders of the corporation. ARTICLE VIII NUMBER AND TERM OF DIRECTORS The number of directors constituting the entire Board of Directors of the corporation shall be fixed by, or in the manner provided in, the Bylaws of the corporation, provided that such number shall be no less than six and no more than twelve (plus such number of directors as may be elected from time to time pursuant to the terms of any Preferred Stock that may be issued and outstanding from time to time), as determined by the Board of Directors. The directors of the corporation shall be divided into three classes ("Class I," "Class II" and "Class III"), as nearly equal in number as possible, as determined by the Board of Directors. At each annual meeting of shareholders, directors elected to succeed those directors whose terms then expire shall be elected for a term of office to expire at the third succeeding annual meeting of shareholders after their election, with each director to hold office until his or her successor shall have been duly elected and qualified. Notwithstanding the foregoing, whenever the holders of any one or more classes or series of Preferred Stock issued by the corporation shall have the right, voting separately by class or series, to 3 elect directors at an annual or special meeting of shareholders, the election, term of office, filling of vacancies and other features of such directorships shall be governed by the terms of these Articles of Incorporation or the resolution or resolutions adopted by the Board of Directors creating such class or series of Preferred Stock, and such directors so elected shall not be divided into classes pursuant to this Article VIII unless expressly provided by such terms. Any director may be removed from office by the shareholders, but only for cause and only by the affirmative vote of a majority of the votes then entitled to be cast in an election of directors. Any vacancy occurring on the Board of Directors, including, but not limited to, a vacancy created by an increase in the number of directors or the removal of a director, shall be filled only by the affirmative vote of a majority of the directors then in office, even if such majority is less than a quorum of the Board of Directors, or by a sole remaining director. If no director remains in office, any vacancy may be filled by the shareholders. Any director elected to fill a vacancy shall serve until the next election of the class for which such director shall have been chosen. ARTICLE IX SHAREHOLDER VOTE Notwithstanding any other provision of these Articles of Incorporation or any provision of law which might otherwise permit a lesser vote or no vote, the affirmative vote of the holders of at least two-thirds (2/3) of the votes entitled to be cast thereon at any annual or special meeting of the shareholders of the corporation shall be required to amend, alter or repeal Articles VII, VIII, IX and X of these Articles of Incorporation.
