The termination of any action, suit or proceedings by judgment, order, settlement, conviction, or upon a plea of nolo contendre or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the Corporation or its Shareholders, and, with respect to any criminal action or proceedings, had reasonable cause to believe that his conduct was unlawful. Section 6.02. INDEMNIFICATION: ACTIONS IN THE RIGHT OF THE CORPORATION. The --------------- ------- -- --- ----- -- --- ----------- Corporation shall indemnify any person who was or is a party to or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the Corporation to procure a judgment in its favor by reasons of the fact that he is or was a director, officer, employee or agent of the Corporation, or is or was serving at the request of -22- the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses (including attorneys' fees) actually and reasonably incurred by him in connection with the defense or settlement of such action or suit if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Corporation or its Shareholders and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable for negligence or misconduct in the performance of his duty to the Corporation unless and only to the extent that the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which such court shall deem proper. Section 6.03. INDEMNIFICATION: MANDATORY AND PERMISSIVE PAYMENTS. (1) To the --------------- --------- --- ---------- -------- extent that a director, officer, employee or agent of the Corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in Section 6.01 or 6.02, or in defense of any claim, issue or matter therein, he shall be indemnified against expenses (including attorneys' fees) actually and reasonably incurred by him in connection therewith. (2) Any indemnification under Sections 6.01 or 6.02 (unless ordered by a court) shall be made by the Corporation only as authorized in the specific case upon a determination that -23- indemnification of the director, officer, employee or agent is proper in the circumstances because he has met the applicable standard of conduct set forth in Section 6.01 and 6.02. Such determination shall be made in either of the following ways: (a) By the Board by a majority vote of a quorum consisting of directors who were not parties to such action, suit or proceeding, except as a greater vote is required by the Articles of Incorporation. (b) If such quorum is not obtainable, or, even if obtainable, a quorum of disinterested directors so directs, by independent legal counsel in a written opinion. (c) By the Shareholders. Section 6.04.
