A. Serial Preferred Stock

1. Issuance in Series. Authority is hereby vested in the Board of Directors to divide the Serial Preferred Stock into and cause the Serial Preferred Stock to be issued in series, to designate each series so as to distinguish the shares thereof from the shares of all other series or classes, to fix the number of shares of each series, and to fix and determine the variations in the relative rights and preferences of each series within the limitations hereinafter set forth in this paragraph. All shares of Serial Preferred Stock shall be identical except as to the following relative rights and preferences, which may be fixed and determined by the Board of Directors and as to which there may be variations between different series:

(a) the rate of dividend, if any, payable on shares of such series, the time of payment and the dates from which dividends shall be cumulative if such dividends shall be cumulative, and the extent of participation rights, if any, of the shares of such series;

(b) any right to vote with holders of shares of any other series or class and any right to vote as a class, either generally or as a condition to specified corporate action;

(c) the price at and the terms and conditions on which shares may be redeemed;

(d) the amount payable upon shares in the event of involuntary liquidation;

(e) the amount payable upon shares in the event of voluntary liquidation;

(f) any sinking fund provisions for the redemption or purchase of shares; and

(g) the terms and conditions on which shares may be may be converted, if the shares of any series are issued with the privilege of conversion.

2. Dividends. The holders of the Serial Preferred Stock of each series as to which the Board of Directors shall have specified a rate of dividend shall be entitled to receive, if and when declared payable by the Board of Directors, dividends at the dividend rate for such series, and not exceeding such rate except to the extent of any participation right. Such dividends shall be payable on such dates as shall be specified for such series. Dividends, if cumulative and in arrears, shall not bear interest.

No dividends shall be declared or paid upon or set apart for the Common Stock or for stock of any other class hereafter created ranking junior to the Serial Preferred Stock in respect to dividends or assets (hereinafter called “Junior Stock”), or for any shares of Serial Preferred Stock which are entitled to participate with the Common Stock, and no shares of Serial Preferred Stock, Common Stock or Junior Stock shall be purchased, redeemed or otherwise reacquired for a consideration, nor shall any funds be set aside for or paid to any sinking fund therefor, unless and until (i) full dividends on the outstanding Serial Preferred Stock at the dividend rate or rates therefor, together with the full additional amount required by any participation right, shall have been paid or declared and set apart for payment wish respect to all past dividend periods, to the extent that the holders of the Serial Preferred Stock are entitled to dividends with respect to any past dividend period, and the current dividend period, and (ii) all mandatory sinking fund payments that shall have become due in respect of any series of the Serial Preferred Stock shall have been made. Unless full dividends with respect to all past dividend periods on the outstanding Serial Preferred Stock at the dividend rate or rates therefor, to the extent that holders of the Serial Preferred Stock are entitled to dividends with respect to any particular past dividend period, together with the full additional amount required by any participation right, shall have been paid or declared and set apart for payment and all mandatory sinking fund payments that shall have become due in respect of any series of the Serial Preferred Stock shall have been made, no distributions shall be made to the holders of the Serial Preferred Stock of any series unless distributions are made to the holders of the Serial Preferred Stock of all series then outstanding in proportion to the aggregate amounts of the deficiencies in payments due to the respective series, and all payments shall be applied first, to dividends accrued and in arrears, next, to any amount required by any participation right, and, finally, to mandatory sinking fund payments. The terms “current dividend period” and “past dividend period” mean, if two or more series of Serial Preferred Stock having different dividend periods are at the time outstanding, the current dividend period or any past dividend period, as the case may be, with respect to each such series.

3. Preference on Liquidation. In the event of any liquidation, dissolution or winding up of the Corporation, the holders of the Serial Preferred Stock of each series shall be entitled to receive, for each share thereof, the fixed liquidation price for such series, plus, in case such liquidation, dissolution or winding up shall have been voluntary, the fixed liquidation premium for such series, if any, together in all cases with a sum equal to all dividends, if any, accrued or in arrears thereon and the full additional amount required by any participation right, before any distribution of the assets shall be made to holders of the Common Stock or Junior Stock; but the holders of the Serial Preferred Stock shall be entitled to no further participation in such distribution. If, upon any such liquidation, dissolution or winding up, the assets distributable among the holders of the Serial Preferred Stock shall be insufficient to permit the payment of the full preferential amounts aforesaid, then such assets shall be distributed among the holders of the Serial Preferred Stock then outstanding, ratably in proportion to the full preferential amounts to which they are respectively entitled. A merger of the Corporation into any other corporation, or merger of any other corporation into the Corporation, or consolidation of the

Corporation with any other corporation or a sale or transfer of the property of the Corporation as or substantially as an entirety shall not be deemed to be a liquidation, dissolution or winding up of the Corporation.

B. Common Stock

1. Dividends. Subject to the provisions of law and the rights of holders of shares at the time outstanding of all classes of stock having prior rights as to dividends, the holders of Common Stock at the time outstanding shall be entitled to receive such dividends at such times and in such amounts as the Board of Directors may deem advisable.

2. Liquidation. In the event of any liquidation, dissolution or winding up (whether voluntary or involuntary) of the Corporation, after payment or provision for the payment of all the liabilities and obligations of the Corporation and all preferential amounts to which the holders of shares at the time outstanding of all classes of stock having prior rights thereto shall be entitled, the remaining net assets of the Corporation shall be distributed ratably among the holders of the shares at the time outstanding of Common Stock.

3. Voting. Except to the extent to which the Board of Directors shall have specified voting power with respect to any other class of stock and except as otherwise provided by law, the exclusive voting power shall be vested in the Common Stock, the holder thereof being entitled to one vote for each share of Common Stock at all meetings of the shareholders of the Corporation.

IV. No Preemptive Rights

No holder of shares of the capital stock of the Corporation of any class shall have any preemptive or preferential right to subscribe to or purchase (i) any shares of capital stock of the Corporation, (ii) any securities convertible into such shares or (iii) any options, warrants or rights to purchase such shares or securities convertible into any such shares.

V. Directors

The business and affairs of the Corporation shall be managed by or under the direction of a Board of Directors consisting of such number of directors as may be fixed from time to time in the bylaws or by resolution adopted by the affirmative vote of a majority of the Directors then in office. 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, with one class to be originally elected for a term of one year, another class to be originally elected for a term expiring in two years, and another class to be originally elected for a term of three years. At each succeeding annual meeting of shareholders beginning in 1993, successors to the class of Directors whose term expires at that annual meeting shall be elected for a three-year term. If the number of Directors has changed, any increase or decrease shall be apportioned among the classes 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. A Director shall hold office until the annual meeting for the year in which his term expires and until his successor shall be elected and shall qualify, subject, however, to prior death, resignation, retirement, disqualification or removal from office.

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 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 applicable thereto, and such Directors so elected shall not be divided into classes pursuant to this Article V unless expressly provided by such terms.

If the office of any Director shall become vacant, the Directors then in office, whether or not a quorum, may by majority vote choose a successor who shall hold office until the next annual meeting of shareholders. In such event, the successor elected by the shareholders at that annual meeting shall hold office for a term that shall coincide with the remaining term of the class of Directors to which that person has been elected. Vacancies resulting from the increase in the number of Directors shall be filled in the same manner.

Directors of the Corporation may be removed by shareholders of the Corporation only for cause and with the affirmative vote of at least two-thirds of the outstanding shares entitled to vote.

Advance notice of shareholder nominations for the election of Directors shall be given in the manner provided in the Bylaws of the Corporation.

(c) Agents and Employees. The Board of Directors is hereby empowered, by a majority vote of a quorum of disinterested Directors, to indemnify or contract in advance to indemnify any person not specified in subsection (a) of this Article against liabilities, fines, penalties and claims imposed upon or asserted against him (including amounts paid in settlement) by reason of having been an employee, agent or consultant of the Corporation, whether or not then continuing so to be, and against all expenses (including counsel fees) reasonably incurred by him in connection therewith, to the same extent as if such person were specified as one to whom indemnification is granted in subsection (a) of this Article.

Corporation or any corporation the majority of the voting stock or which is owned directly or indirectly by the Corporation, (ii) every former Director, officer, employee, agent or consultant of the Corporation, (iii) every person who may have served at the request of or on behalf of the Corporation as a Director, officer, employee, agent, consultant or trustee of another corporation, partnership, joint venture, trust or other entity, and (iv) in all of such cases, his executors and administrators.

(f) Change in Control. In the event there has been a change in the composition of a majority of the Board of Directors after the date of the alleged act or omission with respect to which indemnification is claimed, any determination as to indemnification and advancements of expenses with respect to any claim for indemnification made pursuant to Subsection (a) of this Article VI shall be made by special legal counsel agreed upon by the Board of Directors and the proposed indemnitee. If the Board of Directors and the proposed indemnitee are unable to agree upon such special legal counsel, the Board of Directors and the proposed indemnitee each shall select a nominee, and the nominees shall select such special legal counsel.

VII. Shareholder Approval of Certain Transactions

An amendment of the Corporation’s Articles of Incorporation, a plan of merger or share exchange, a transaction involving the sale of all or substantially all the Corporation’s assets other than in the regular course of business and a plan of dissolution shall be approved by the vote of a majority of all the votes entitled to be cast on such transactions by each voting group entitled to vote on the transaction at a meeting at which a quorum of the voting group is present, provided that the transaction has been approved and recommended by at least two-thirds of the Directors in office at the time of such approval and recommendation. If the transaction is not so approved and recommended, then the transaction shall be approved by the vote of eighty percent (80%) or more of all the votes entitled to be cast on such transactions by each voting group entitled to vote on the transaction.
