A-1 13 Section 2. Dividends and Distributions. (A) Subject to the rights of the holders of any shares of any series of Preferred Stock (or any similar stock) ranking prior and superior to the Series A Preferred Stock with respect to dividends, the holders of shares of Series A Preferred Stock, in preference to the holders of Common Stock, par value $.01 per share (the "Common Stock"), of the Corporation, and of any other junior stock, shall be entitled to receive, when, as and if declared by the Board of Directors out of funds legally available for the purpose, quarterly dividends payable in cash on the first day of March, June, September and December in each year (each such date being referred to herein as a "Quarterly Dividend Payment Date"), commending on the first Quarterly Dividend Payment Date after the first issuance of a share or fraction of a share of Series A Preferred Stock, in an amount per share (rounded to the nearest cent) equal to the greater of (a) $1 or (b) subject to the provision for adjustment hereinafter set forth, 100 times the aggregate per share amount of all cash dividends, and 100 times the aggregate per share amount (payable in kind) of all non-cash dividends or other distributions, other than a dividend payable in shares of Common Stock or a subdivision of the outstanding shares of Common Stock (by reclassification or otherwise), declared on the Common Stock since the immediately preceding Quarterly Dividend Payment Date or, with respect to the first Quarterly Dividend Payment Date, since the first issuance of any share or fraction of a share of Series A Preferred Stock.

(a) The business and affairs of the Corporation shall be managed by or under the direction of a Board of Directors. The number of directors of the Corporation shall be fixed from time to time by resolution adopted by the affirmative vote of a majority of the entire Board of Directors of the Corporation, except that the minimum number of directors shall be fixed at not fewer than nine and the maximum number of directors shall be fixed at not more than twelve. The directors shall be divided into three classes, designated as Class I, Class II and Class III. Each class shall consist, as nearly as may be possible, of one-third of the total number of directors constituting the entire Board of Directors. At the 1989 annual meeting of shareholders and at each succeeding annual meeting of shareholders, successors to the class of directors whose terms of office expire at that annual meeting shall be elected to hold office for a three-year term, so that the term of office of one class of directors shall expire in each year. Any vacancy occurring on the Board of Directors through death, resignation, retirement, disqualification, removal or other cause, or resulting from an increase, the number of directors, may be filled by the affirmative vote of a majority of the then remaining directors, through less than a quorum, or by the sole remaining director for a term of office continuing only until the next election of directors by the shareholders. If the number of directors is changed, any increase or decrease shall be apportioned among the classes of directors so as to maintain the number of directors in each class as nearly equal as possible, but in no case will a decrease in the number of directors shorten the term of any incumbent director. When the number of directors is increased by the Board of Directors and any newly created directorships are filled by the Board of Directors, there shall be no classification of the additional directors until the next election of directors by the shareholders. (b) Any director may be removed from office at any time either (i) by vote of the holders of two-thirds of the shares entitled to vote at an election of directors, but only for cause, or (ii) by vote of two-thirds of the other directors, with or without cause. (c) Notwithstanding the foregoing paragraphs, whenever the holders of any one or more class or series of Preferred Stock issued by the Corporation shall have the right, voting separately by class or series, to elect directors at an annual or special 31 meeting of shareholders, the election, term of office, filling of vacancies and other features of such directorships shall be governed by the terms of the Articles of Incorporation applicable thereto. The then authorized number of directors of the Corporation shall be increased by the number of additional directors to be elected, and such directors so elected shall not be divided into classes pursuant to this Article SIXTH unless expressly provided by such terms. (d) Nominations for election to the Board of Directors of the Corporation at a meeting of shareholders may be made by the Board of Directors, on behalf of the Board of Directors by any nominating committee appointed by the Board of Directors, or by any shareholder of the Corporation entitled to vote for the election of directors at a meeting. Nominations, other than those made by or on behalf of the Board of Directors, shall be made by notice in writing delivered to or mailed, postage prepaid, and received by the Secretary of the Corporation at least 90 days but no more than 120 days prior to the anniversary date of the immediately preceding annual meeting of shareholders. The notice shall set forth (i) the name and address of the shareholder who intends to make the nomination; (ii) the name, age, business address and, if known, residence address of each nominee; (iii) the principal occupation or employment of each nominee; (iv) the number of shares of stock of the Corporation which are beneficially owned by each nominee and by the nominating shareholder; (v) any other information concerning the nominee that must be disclosed of nominees in proxy solicitations pursuant to Regulation 14A of the Securities Exchange Act of 1934 (or any subsequent provisions replacing such Regulation); and (vi) the executed consent of each nominee to serve as a director of the Corporation, if elected. The chairman of the meeting of shareholders may, if the facts warrant, determine that a nomination was not made in accordance with the foregoing procedures, and if the chairman should so determine, the chairman shall so declare to the meeting and the defective nomination shall be disregarded. 2
