ARTICLE EIGHT INDEMNIFICATION 8.1 (a) Under the circumstances prescribed in section 8.2 hereof, the corporation shall indemnify and hold harmless any person who was or is a party or is threatened to be made a party 7. to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation), by reason 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 the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if he acted in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of NOLO CONTENDERE or its equivalent, shall not, of itself, create a presumption that the person did not act in a manner which he reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that his conduct was unlawful. (b) Under the circumstances prescribed in section 8.2 hereof, the corporation shall indemnify and hold harmless any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in 8. the right of the corporation to procure a judgment in its favor by reason of the fact he is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of 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; 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 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 the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the court shall deem proper. 8.2 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 8.1 hereof, 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. Except as provided in the preceding sentence and except as may be ordered by a court, any indemnification under section 8.1 hereof shall be made by the 9. corporation only as authorized in the specific case upon a determination that 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 8.1 hereof. Such a determination shall be made (1) by the Board of Directors by a majority vote of a quorum consisting of directors who were not parties to such action, suit or proceeding, or (2) by independent legal counsel employed by the corporation, in a written opinion, if such a quorum is not obtainable, or, even if obtainable a quorum of disinterested directors so directs, or (3) by the affirmative vote of a majority of the shares entitled to vote thereon. 8.3 Expenses incurred in defending a civil or criminal action, suit or proceeding may be paid by the corporation in advance of the final disposition of such action, suit or proceeding as authorized by the Board of Directors generally or as to a specific case or as to a specific person or persons (designated by name, title or class of persons), upon receipt of an undertaking by or on behalf of the director, officer, employee or agent to repay such amount if it shall ultimately be determined that he is not entitled to be indemnified by the corporation as authorized in this Article Eight. 8.4 The provisions for indemnification and advancement of expenses provided by this Article Eight shall not be deemed exclusive of any other rights, in respect of indemnification or otherwise, to which those seeking indemnification may be entitled 10. under any bylaw, agreement, either specifically or in general terms, resolution, or approved by the affirmative vote of the holders of a majority of the shares entitled to vote thereon taken at a meeting the notice of which specified that such bylaw, resolution or agreement would be placed before the shareholders, both as to action by a director, officer, employee or agent in his official capacity and as to action in another capacity while holding such office or position, except that no such other rights, in respect to indemnification or otherwise, may be provided or granted with respect to the liability of any director, officer, employee or agent for (a) any appropriation, in violation of his duties, of any business opportunity of the corporation; (b) acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; (c) liabilities of a director imposed by section 14-2-832 of the Nebraska Business Corporation Act; or (d) any transaction from which the director, officer, employee or agent derived an improper personal benefit. 8.5 (a) The corporation may purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against any liability asserted against him and incurred by him in any such capacity, or arising out of his status as such, whether or not the corporation would have the power to indemnify him against such liability 11. under the provisions of this Article Eight. (b) If any expenses or other amounts are paid by way of indemnification, otherwise than by court order or action by the shareholders or by an insurance carrier pursuant to insurance maintained by the corporation, the corporation shall, not later than the next annual meeting of shareholders unless such meeting is held within three months from the date of such payment, and, in any event within 15 months from the date of such payment, send by first class mail (or if the corporation shall have at the time more than 500 shareholders entitled to vote, by such other means as may be authorized by the Nebraska Business Corporation Act for notices of meetings of shareholders), to its shareholders of record at the time entitled to vote for the election of directors a statement specifying the persons paid, the amounts paid, and the nature and status at the time of such payment of the litigation or threatened litigation. 8.6 As a condition to any such right of indemnification, or to receive advancement of expenses, the corporation may require that it be permitted to participate in the defense of any such action or proceeding through legal counsel designated by the corporation and at the expense of the corporation. 8.7 The rights to indemnification and advancement of expenses provided in this Article Eight shall continue notwithstanding that a person who would otherwise have been entitled to indemnification or advancement of expenses hereunder shall have ceased to be a director, officer, employee or agent, 12. and shall inure to the benefit of the heirs, executors and administrators of such persons. 13.
