The New Capital Securities will be issued under an Amended and Restated Declaration of Trust for the Trust, dated February 5, 1997 (the "Amended Declaration"), among the Corporation, as sponsor, The Chase Manhattan Bank, as property trustee, Chase Manhattan Bank Delaware, as Delaware trustee, and the Administrative Trustees named therein, while the New Junior Subordinated Debentures will be issued under an Indenture, dated as of February 5, 1997 (the "Indenture"), between the Corporation and The Chase Manhattan Bank, as debenture trustee. 2 We have examined such documents and records as we deemed appropriate, including the following: (i) Copy of the Amended and Restated Certificate of Incorporation of the Corporation, certified as of a recent date by the Secretary of State of the State of Delaware; (ii) Copy of the By-Laws of the Corporation, as amended, certified as of a recent date by the Secretary of the Corporation to be a true and complete copy; (iii) Copies, certified by the Secretary of the Corporation to be true and complete copies, of the resolutions duly adopted by the Board of Directors of the Corporation on January 20, 1997 and by the Pricing Committee of the Board of Directors on January 31, 1997 and on February 18, 1997 which, among other things, authorized the filing of the Registration Statement and the exchange of the New Capital Securities, the New Junior Subordinated Debentures and the New Guarantee in the circumstances referred to above; (iv) Minute book records of the Corporation and its subsidiaries; (v) Executed counterparts of the Amended Declaration; (vi) Specimen of the New Capital Security; (vii) Executed counterparts of the Indenture; (viii) Specimen of the New Junior Subordinated Debenture; (ix) Executed counterparts of the New Guarantee; and (x) Executed counterparts of the Registration Rights Agreement, dated as of February 5, 1997 (the "Registration Rights Agreement"), among the Trust, the Corporation and the Initial Purchasers named therein. In addition, as to questions of fact material to our opinions, we have relied upon certificates of officers of the Corporation, the Administrative Trustees of the Trust and public officials. In the course of our examination, we have assumed the legal capacity of all natural persons, the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as certified or photostatic copies and the authenticity of the originals of such latter documents. In making our examination of documents executed by parties other than the Corporation or the Trust, we have assumed that such parties had the power, corporate or other, to enter into and perform all obligations 2 3 thereunder and have also assumed the due authorization by all requisite action, corporate or other, and execution and delivery by such parties of such documents and the validity and binding effect thereof on such parties. Based upon the foregoing, we are of the opinion that: (1) The New Junior Subordinated Debentures have been duly authorized by all requisite corporate action of the Corporation and, when executed and authenticated in the manner provided for in the Indenture and delivered against surrender and cancellation of a like aggregate principal amount of Old Junior Subordinated Debentures as contemplated in the Registration Rights Agreement, the New Junior Subordinated Debentures will constitute valid and binding obligations of the Corporation entitled to the benefits of the Indenture and enforceable against the Corporation in accordance with their terms, except as enforcement thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to or affecting creditors' rights generally or by general equitable principles (regardless of whether considered in a proceeding in equity or at law). (2) The New Guarantee has been duly authorized by all requisite corporate action of the Corporation and, when executed and delivered to The Chase Manhattan Bank, as guarantee trustee, as contemplated in the Registration Rights Agreement, the New Guarantee will constitute a valid and binding agreement of the Corporation, enforceable against the Corporation in accordance with its terms, except as enforcement thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to or affecting creditors' rights generally or by general equitable principles (regardless of whether considered in a proceeding in equity or at law). We are members of the Bar of the State of New York and we express no opinion as to the laws of any jurisdiction other than the laws of the State of New York and the federal laws of the United States of America and the Delaware General Corporation Law. We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference to our firm under the caption "Legal Matters" contained in the Prospectus included therein. In giving this consent, we do not thereby admit that we come within the category of persons whose consent is required under Section 7 of the Securities Act or the Rules and Regulations of the Securities and Exchange Commission thereunder. Very truly yours, /s/ Dewey Ballantine 3
