         was a director of the Corporation, provided that such person is
         determined in the manner specified in Indiana Code Section 23-1-37-12
         to have met the standard of conduct specified in Indiana Code Section

         director in connection with a proceeding by or in the right of the
         Corporation, the Corporation shall report the indemnification or

         Incorporation, the Corporation's bylaws, any general or specific action
         of the board of directors or the shareholders of the Corporation, or
         any contract relating to indemnification of or the advancement of
         expenses to any director, officer, employee or agent of the
