ARTICLE 8. LIABILITY OF DIRECTORS AND OFFICERS; INDEMNIFICATION. 8.1 LIMITATION OF LIABILITY. The personal liability of the directors and officers of the Corporation for monetary damages shall be eliminated to the fullest extent permitted by the MBCA as it exists on the effective date of these Articles of Incorporation or as such law may be thereafter in effect. No amendment, or repeal of this Article 8.1 shall adversely affect the rights provided hereby with respect to any claim, issue or matter in any proceeding that is based in any respect on any alleged action or failure to act prior to such amendment, or repeal. 8.2 INDEMNIFICATION. The Corporation shall indemnify any person made or threatened to be made a party to any proceeding by reason of the fact that such person is or was a director or officer of the Corporation or any predecessor of the Corporation, or who, while a director or officer of the Corporation, is or was serving at the Corporation’s request as a director, officer, employee, or agent of another corporation, partnership, joint venture, trust, employee benefit plan, or other entity, against expenses (including attorneys’ fees), judgments, fines, excise taxes, and amounts paid in settlement actually and reasonably incurred by such person in connection with such proceeding to the fullest extent authorized or permitted by the MBCA, as now or hereafter in effect.

(2) the aggregate amount of the cash and the Fair Market Value as of the date of the consummation of the Business Combination of consideration other than cash to be received per share by holders of shares of any other class of outstanding Voting Stock shall be at least equal to the highest of the following (it being intended that the requirements of this clause (2) shall be required to be met with respect to every class of outstanding Voting Stock, whether or not the Interested Shareholder has previously acquired any shares of a particular class of Voting Stock): (a) (if applicable) the highest per share price (including any brokerage commissions, transfer taxes and soliciting dealers’ fees) paid by the Interested Shareholder for any shares of such class of Voting Stock acquired by it (i) within the five-year period immediately prior to the Announcement Date or (ii) in the transaction in which it became an Interested Shareholder, whichever is higher;

(b) the Fair Market Value per share of such class of Voting Stock on the Announcement Date or on the Determination Date, whichever is higher; and (c) (if applicable) the highest preferential amount per share to which the holders of shares of such class of Voting Stock are entitled in the event of any liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary. (3) The consideration to be received by holders of a particular class of outstanding Voting Stock (including Common Stock) shall be in cash or in the same form as the Interested Shareholder has previously paid for shares of such class of Voting Stock. If the Interested Shareholder has paid for shares of any class of Voting Stock with varying forms of consideration, the form of consideration for such class of Voting Stock shall be either cash or the form used to acquire the largest number of shares of such class of Voting Stock previously acquired by it. The price determined in accordance with clauses (1) and (2) of this paragraph (B) shall be subject to appropriate adjustment in the event of any stock dividend, stock split, combination of shares or similar event. (4) After such Interested Shareholder has proposed such a Business Combination and prior to the consummation of such Business Combination; (a) except as approved by a majority of the Disinterested Directors, there shall have been no failure to declare and pay at the regular date therefor any full quarterly dividends (whether or not cumulative) on the outstanding Preferred Stock of the Corporation; (b) there shall have been (i) no reduction in the quarterly rate of dividends paid on the Common Stock (except as necessary to reflect any subdivision of the Common Stock), except as approved by a majority of the Disinterested Directors, and (ii) an increase in such quarterly rate of dividends paid on such Common Stock as necessary to reflect any reclassification (including any reverse stock split), recapitalization, reorganization or any similar transaction which has the effect of reducing the number of outstanding shares of the Common Stock, unless the failure so to increase such annual rate is approved by a majority of the Disinterested Directors; and (c) such Interested Shareholder shall not have become the beneficial owner of any additional shares of Voting Stock except as part of the transaction which results in such Interested Shareholder becoming an Interested Shareholder. (5) A proxy or information statement describing the proposed Business Combination and complying with the requirements of the Securities Exchange Act of 1934, as amended (or any subsequent provisions replacing such) (hereinafter referred to as the “Act”), and the rules and regulations of the Securities and Exchange Commission thereunder shall be mailed to the shareholders of the Corporation at least 30 days prior to the consummation of such Business Combination (whether or not such proxy or information statement is required to be mailed pursuant to the Act.)
