TRANSFER OF STOCK

     Section 4. Upon surrender to the corporation or the transfer agent of the corporation of a certificate for shares duly endorsed or accompanied by proper evidence of succession, assignment or authority to transfer, it shall be the duty of the corporation to issue a new certificate to the person entitled thereto, cancel the old certificate and record the transaction upon its books.

     Section 6. The Corporation shall indemnify any person who was or is a party or its threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, except in 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 in connection with such action, suit or proceedings if he acted in good faith and in a manner such person 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 good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the Corporation and that, with respect to any criminal action or proceeding, he had reasonable cause to believe that his conduct was unlawful.

     Section 7. The Corporation shall indemnify 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 the right of the Corporation to procure a judgment in its favor 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 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 which he reasonably believed to be in or not opposed to the best interests of the Corporation; except no indemnification shall be made by the Corporation in respect of any claim, issue or matter as to which such person has 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 determines 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 indemnification for such expenses as the court deems proper.

     Any indemnification under Section 6 or 7 of this Article, unless ordered by a court, shall be made by the 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 Sections 6 and 7. Determination as to such conduct shall be made:

     (1) By the stockholders; or

     (2) By the Board of Directors by majority vote of a quorum consisting of Directors who were not parties to such act, suit or proceeding; or

     (3) If such a quorum of disinterested Directors so orders, by independent legal counsel in a written opinion; or

     (4) If such a quorum of disinterested Directors cannot be obtained, by independent legal counsel in a written opinion.

     A Director, officer, employee or agent of the Corporation who is seeking indemnification shall make a written request for such indemnification to the Board. Upon receipt of such request the Board shall act promptly and in compliance with the procedure set forth above.

     Expenses incurred in defending any proceeding shall be advanced by the Corporation prior to the final disposition of such proceeding upon receipt of an undertaking by or on behalf of the Director, officer, employee or agent to repay such amount unless it shall be determined ultimately that the agent is entitled to be indemnified as authorized in this Section.

     Section 8. The Corporation shall indemnify any Director, officer, employee or agent of the Corporation who has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in this Section, or in defense of any item, issue or matter therein, against expenses, including attorneys’ fees, actually and reasonably incurred by him in connection with such defense.
