I have also examined originals or copies, certified or otherwise identified to my satisfaction, of such records of the Company and such agreements, certificates of public officials, certificates of officers or other representatives of the Company and others, and such other documents, certificates and records as I have deemed necessary or appropriate as a basis for the opinions set forth herein. In my examination, I have assumed the legal capacity of all natural persons, the genuineness of all signatures, the authenticity of all documents submitted to me as originals, the conformity to original documents of all documents submitted to me as certified, photostatic or facsimile copies and the authenticity of the originals of such latter documents. In making my examination of documents executed by parties other than the Company, I have assumed that such parties had the power, corporate or other, to enter into and perform all obligations 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. I am a member of the Bar in the State of Ohio, and I do not express any opinion as to the laws of any other jurisdiction other than the laws of the United States of America to the extent referred to specifically herein. Insofar as the opinions set forth below relate to the Indenture and the Securities as valid, binding and enforceable obligations of the Company, I have relied solely upon an opinion letter of even date herewith from Skadden, Arps, Slate, Meagher & Flom LLP, New York, New York, with respect to all matters of New York law related thereto. This opinion is limited to the laws, including the rules and regulations, as in effect on the date hereof. Based upon and subject to the foregoing, I am of the opinion that: 1. The Company has been duly incorporated and is validly existing as a corporation in good standing under the laws of Ohio, with corporate power and authority to own its properties and conduct its business as described in the Prospectus. 2. The issuance and sale of the Securities have been duly authorized by the Company; the Securities, when executed and authenticated in accordance with the terms of the Indenture and delivered to and paid for by the Underwriters in accordance with the terms of the Underwriting Agreement, will be valid and binding obligations of the Company entitled to the benefits of the Indenture and enforceable against the Company in accordance with their terms, except (a) to the extent that enforcement thereof may be limited by (i) bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer or other similar laws now or hereafter in effect relating to creditors' rights generally and (ii) general principles of equity (regardless of whether enforceability is considered in a proceeding at law or in equity) and (b) I express no opinion as to Section 515 of the Indenture. 3. The Indenture has been duly authorized, executed and delivered by the Company and is a valid and binding agreement of the Company, enforceable against the Company in accordance with its terms, except (a) to the extent that enforcement thereof may be limited by (i) bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer or other similar laws now or hereafter in effect relating to creditors' rights generally and (ii) general principles of equity (regardless of whether enforceability is considered in a proceeding at law or in equity) and (b) I express no opinion as to Section 515 of the Indenture. I hereby consent to the filing of this opinion with the Commission as Exhibit 5(a) to the Form 8-K. In giving this consent, I do not thereby admit that I am in the category of persons whose consent is required under Section 7 of the Act or the Rules and Regulations of the Commission promulgated thereunder. This opinion is expressed as of the date hereof unless otherwise expressly stated, and I disclaim any undertaking to advise you of any subsequent changes of the facts stated or assumed herein or any subsequent changes in applicable law. Very truly yours, /s/ David L. Santez
