Based upon the foregoing, and upon our examination of such legal and factual matters as we deem necessary in order to furnish this opinion: 1. It is our opinion that the Shares and the participation interests in the Plan, when issued as contemplated by the Plan, will be duly authorized, legally issued, fully paid and non- assessable, assuming the Shares are not issued for less than par value; and 2. It is our opinion that the provisions of the written Plan document in effect on the date hereof comply with the requirements of the Employee Retirement Income Security Act of 1974 applicable to such provisions. We hereby consent to the filing of this opinion as an exhibit to the Registration Statement. JONES, WALKER, WAECHTER, POITEVENT, CARRERE & DENEGRE By: /s/Margaret F. Murphy Margaret F. Murphy
