The termination of any third party proceeding by judgment, order, settlement, indictment, conviction or upon a plea of nolo contendere or its equivalent, shall not of itself create a presumption that the authorized representative did not act in good faith and in a manner which such person reasonably believed to be in or not opposed to, the best interests of the Corporation, and, with

-12-

respect to any criminal third party proceeding, had reasonable cause to believe that such conduct was unlawful.

SECTION 7.03. Mandatory Indemnification of Authorized Representatives. To the extent that an authorized representative of the Corporation has been successful on the merits or otherwise in defense of any third party or corporate proceeding or in defense of any claim, issue or matter therein, such person shall be indemnified against expenses actually and reasonably incurred by such person in connection therewith.
