The termination of any action, suit or proceeding by judgment, order, settlement or conviction, or on 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 with respect to any criminal action or proceeding had reasonable cause to believe that his conduct was unlawful.

(c) To the extent that a director, officer, employee or agent of a corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in sub-sections (a) and (b), or in defense of any claim, issue or matter therein he shall be indemnified against expenses (including attorney fees) actually and reasonably incurred by him in connection therewith. (d) Any indemnifications under subsections (a) and (b) (unless ordered by a court) shall be made by the corporation only as authorized in the specific case, by reimbursement on a current basis or otherwise, 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 subsections (a) and (b). Such 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 the Board of Directors, whether interested or disinterested, and whether or not a quorum is obtainable, if based upon a written opinion of legal counsel, or (3) by the stockholders. (e) 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.
