Each such Class shall consist, as nearly as possible, of one-third of the total number of directors comprising the entire Board of Directors.

In the event of an increase or decrease in the number of directors, (1) each director then serving as such shall nevertheless continue as a director of the class in which he or she is a member until the expiration of his or her current term, or his or her earlier resignation, removal from office or death; and (2) the newly created or eliminated directorships resulting from such increase or decrease shall be appointed by the Board of Directors, in its sole discretion, among the three classes of directors so as to maintain such classes as nearly equal as possible.

Section 6.4     Removal. No director may be removed from office by the shareholders without cause except by a vote of 80% of the outstanding shares then entitled to vote. Except as otherwise provided by law, cause for removal shall exist only if the Board of Directors has reasonable grounds to believe that the corporation has suffered or will suffer substantial injury as a result of the gross negligence or dishonesty of the directors whose removal is proposed.

Section 6.5     Nominations. Nominations for election to the Board of Directors may be made by the Board of Directors or by any stockholder of any outstanding class of stock of the corporation entitled to vote for the election of directors. Nominations, other than those made by the Board of Directors, must be made in writing and delivered or mailed to the Chairman of the corporation not less than fourteen (14) days nor more than sixty (60) days prior to any meeting of shareholders called for the election of directors; provided, however, if less than twenty-one (21) days’ notice of the meeting is given to shareholders, such nominations shall be mailed or delivered no later than the close of business on the seventh day following the day on which the notice of meeting was mailed. Such notification shall contain the following information to the extent known to the notifying shareholder: (a) the name and address of each proposed nominee; (b) the principal occupation of each proposed nominee; (c) the total number of shares of stock of the corporation that will be voted for each proposed nominee; (d) the name and address of the notifying shareholder; and (e) the number of shares of common stock of the corporation owned by the notifying shareholder.

(b)     An “interested shareholder”:

(1)     Includes any person or group of affiliated persons who beneficially own twenty percent or more of the outstanding voting shares of a corporation; and

(2)     Excludes any person who, in good faith and not for the purpose of circumventing this Article, is an agent, custodial bank, broker, nominee, or trustee for another person, if such other person is not an interested shareholder under Section 7.1(b)(1) of this Article.

(c)     An “affiliated person” is any person who either acts jointly or in concert with, or directly or indirectly controls, is controlled by, or is under common control with another person.

All outstanding shares entitled to vote under applicable law or the Articles of Incorporation shall be entitled to be counted under this Section 7.2, except shares owned by or voted under the control of an interested shareholder may not be counted to determine whether shareholders have approved a transaction for purposes of this Section 7.2. The vote of the shares owned by or voted under the control of an interested shareholder, however, shall be counted in determining whether a transaction is approved under other provisions of applicable law and for purposes of determining a quorum.

Section 7.3     Exemptions. The special shareholder approval provisions of Section 7.2 of this Article shall not apply to a transaction:

(a)     Board Approval. Approved by a majority vote of the board of directors. For such purpose, the vote of directors whose votes are otherwise entitled to be counted under the Articles of Incorporation and applicable law who are directors or officers of, or have a material financial interest in, an interested shareholder, or who were nominated for election as a director as a result of an arrangement with an interested shareholder and first elected as a director within twenty-four months of the proposed transaction, shall not be counted in determining whether the transaction is approved by such directors; or

(b)     Fair Value. In which a majority of directors whose votes are entitled to be

counted under Section 7.3(a) determines that the fair market value of the consideration to be received by noninterested shareholders for shares of any class of which shares are owned by an interested shareholder is not less than the highest fair market value of the consideration paid by any interested shareholder in acquiring shares of the same class within twenty-four months of the proposed transaction.

Section 7.4     Amendment or Repeal of Article VII. This Article may be amended or repealed only by the affirmative vote of the holders of two-thirds of the shares entitled to be counted under this Section 7.4. All outstanding shares entitled to vote under applicable law or the Articles of Incorporation shall be entitled to be counted under this Section 7.4, except shares owned by or voted under the control of an interested shareholder may not be counted to determine whether shareholders have voted to approve the amendment or repeal. The vote of the shares owned by or voted under the control of an interested shareholder, however, shall be counted in determining whether the amendment or repeal is approved under other provisions of applicable law and for purposes of determining a quorum.

Section 7.5     Non-Exclusivity. The requirements imposed by this Article are to be in addition to, and not in lieu of requirements imposed on any transaction by any provision of applicable law, or any other provision of the Articles of Incorporation, or the Bylaws or otherwise.
