The Securities are being registered for offering and sale from time to time as provided by Rule 415 under the Act.

The Senior Debt Securities are to be issued under an Indenture, dated as of October 25, 1989, by and between the Company and The Bank of New York Trust Company, N.A., as successor to The First National Bank of Chicago as trustee, as amended by a Supplemental Indenture, dated as of March 18, 2003, by and between the Company and The Bank of New York Trust Company, N.A. as successor to Bank One Trust Company, N.A. as trustee (as so amended, the “Senior Debt Indenture”). The Subordinated Debt Securities are to be issued under an Indenture, dated as of June 4, 2003, by and between the Company and The Bank of New York Trust Company, N.A., as successor to Bank One Trust Company, N.A. as trustee (the “Subordinated Debt Indenture”). The Junior Subordinated Debt Securities are to be issued under an Indenture to be entered into by and between the Company and The Bank of New York Trust Company, N.A., as trustee (the “Junior Subordinated Indenture”).

The Depositary Shares are to be issued under deposit agreements, each between the Company and a depositary to be identified in the applicable agreement (each, a “Deposit Agreement”). The Warrants are to be issued under common stock and preferred stock warrant agreements or debt warrant agreements, as applicable, each between the Company and a warrant agent to be identified in the applicable agreement (each, a “Warrant Agreement”). The Purchase Contracts are to be issued under purchase contract agreements, each between the Company and The Bank of New York Trust Company, N.A., as successor to Bank One Trust Company, N.A., as purchase contract agent (each, a “Purchase Contract Agreement”). The Units may be issued under unit agreements or other agreements, each between the Company and a unit agent to be identified in the applicable agreement (each, a “Unit Agreement”). The Rights are to be issued under the Rights Agreement, dated as of March 12, 1999, by and between the Company and First Chicago Trust Company as rights agent (the “Rights Agreement”).

In connection with the furnishing of the opinions below, I have examined original or copies of the following documents:

1. the Registration Statement;

2. the Senior Debt Indenture (including the form of Senior Debt Securities included therein) filed as Exhibits 4.1 and 4.11 to the Registration Statement;

4. the form of Junior Subordinated Indenture (including the form of Junior Subordinated Debt Securities included therein) filed as Exhibit 4.3 to the Registration Statement;

5. the form of Deposit Agreement (including the form of depositary receipt included therein) filed as Exhibit 4.4 to the Registration Statement;

8. the form of Pledge Agreement filed as Exhibit 4.10 to the Registration Statement; and

9. the Rights Agreement filed as Exhibit 4.6 to the Registration Statement.

In addition, I have examined the Restated Certificate of Incorporation, as amended, and the By-laws, as amended through December 4, 2003, of the Company as in effect on the date of this letter, resolutions of the Company’s Board of Directors, and such other documents, corporate records, certificates of public officials and other instruments as I deemed appropriate.

I have assumed, without independent investigation, the genuineness of all signatures, the legal capacity of all individuals who have executed any of the documents reviewed by me, the authenticity of all documents submitted to me as originals, the conformity to the originals of all documents submitted to me as certified, photostatic, reproduced or conformed copies of valid existing agreements or other documents, the authenticity of the latter documents and that the statements regarding matters of fact in the certificates, records, agreements, instruments and documents that I have examined are accurate and complete.

I have also assumed that at or prior to the time of the execution, issuance, sale and delivery of any of the Securities, the Board of Directors of the Company or the Executive Committee of the Board of Directors of the Company, or any other committee as may be designated by the Board of Directors for such purpose (each, an “Authorized Committee”), as applicable, shall have duly established the terms of such Security (other than the Common Stock and the Rights) and duly authorized the issuance and sale of such Security (other than the Rights) and that such authorization shall not have been modified or rescinded. I have further assumed that none of the terms of any Security to be established subsequent to the date of this letter, nor the execution, issuance, sale and delivery of such Security, nor the compliance by the Company with the terms of such Security will violate any applicable law or will result in a violation of any provision of
