We have reviewed such corporate records, certificates and other documents, and such questions of law, as we have considered necessary or appropriate for the purposes of this opinion. We have assumed that all signatures are genuine, that all documents submitted to us as originals are authentic and that all copies of documents submitted to us conform to the originals. We have assumed further that the Trustee has duly authorized, executed and delivered the Indenture.

We have assumed further that the Company and the Subsidiary Guarantors that are incorporated or formed in the State of Ohio, the State of Arizona, the Commonwealth of Kentucky, the province of Ontario, Canada and the province of Nova Scotia, Canada (such Subsidiary Guarantors, which are listed on Schedule B hereto, the “Non-Covered Guarantors”) are validly existing and in good standing under the laws of the jurisdiction in which each is incorporated or formed, as applicable, and that each has the power, authority and legal right to execute, deliver and perform the Indenture, the Notes and the Guarantees, as applicable. We have assumed further that each of the Company and the Non-Covered Guarantors has duly authorized, executed and delivered the Indenture, the Notes and the Guarantees, as applicable. With respect to all matters of Ohio law, we note that you are relying on an opinion of David Bialosky, Senior

Vice President, General Counsel and Secretary of the Company, which is filed as Exhibit 5.2 to the Company’s Current Report on Form 8-K filed on the date hereof (the “Current Report on Form 8-K”).

We have relied as to certain matters on information obtained from public officials, officers of the Company and the Subsidiary Guarantors, and other sources believed by us to be responsible.

Based upon the foregoing, we are of the opinion that, when (i) the Notes have been duly executed by the Company and authenticated by the Trustee in accordance with the Indenture, and (ii) the Notes and the Guarantees have been duly issued and delivered against payment therefor as contemplated by the Prospectus, the Notes and Guarantees will constitute the valid and binding obligations of the Company and the Subsidiary Guarantors, respectively, enforceable against the Company and the Subsidiary Guarantors, respectively, in accordance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and other laws of general applicability relating to or affecting creditors’ rights and to general equity principles.
