executed in connection therewith and/or referenced herein. We have not independently reviewed, established or verified the accuracy or completeness of the information set forth or certified in such documents. However, we have no reason to believe that the information contained in such documents is not complete and accurate. Except as otherwise expressly stated herein, this opinion should in no way be construed as passing upon the accuracy or completeness of any of the representations or warranties which may be or have been made to you in the Indentures (or documents referenced therein), the Authority Documents, or on any other matters, legal or otherwise, not specifically covered herein.

We further advise you that our representation of the Ohio Guarantors has been limited to this particular matter and, with respect to this particular matter, has been limited and does not involve an overall or detailed knowledge of the affairs, business operations or financial condition, past or present, of the Ohio Guarantors. Furthermore, we have not made any special examination of and are not expressing an opinion regarding the affairs or financial condition of the Ohio Guarantors.

We are qualified to practice law only in the State and we do not purport to be experts on, or to express an opinion herein concerning, the law of any jurisdiction other than the State and the laws of the United States of general application to transactions in the State. We express no opinion as to (i) the laws of any other jurisdiction, (ii) matters of municipal law or the laws of any local agencies within any state or (iii) state or federal tax, securities or antitrust laws. We further express no opinion with respect to the effect of any law other than the law of the State and the federal law of the United States. To the extent that the interpretation, construction or enforcement of the Indentures and the other documents referred to herein may be governed by the laws of any jurisdiction other than that of the State, we have assumed that the laws of such jurisdiction are identical to the laws of the State.

As used herein with respect to the existence or absence of facts, “to our knowledge,” “known to us,” or words or phrases of similar import shall mean, during the course of our representation of the Ohio Guarantors, no information that would give us current actual knowledge of the accuracy or inaccuracy of such statement has come within the conscious awareness of lawyers in our office who are actively involved in preparing this legal opinion or other documents in furtherance of the transaction or who we reasonably believe may have knowledge with respect to the matters addressed in this opinion. Information shall not be deemed to be within our knowledge if such information might have been revealed if there had been undertaken a canvass of all lawyers within our Firm or a general search of the Firm’s files. We have not made and accept no responsibility to make any investigation of the existence or absence of such facts and no inference as to our knowledge of the existence or absence of such facts should be drawn from our representation of the Ohio Guarantors.

In rendering the opinions herein contained, we have assumed the following with your approval:

(i) the legal capacity of each natural person;

(ii) the due formation of all parties to the Indentures (other than the Ohio Guarantors);

(iii) the valid legal existence and good standing of all parties to the Indentures (other than the legal existence of the Ohio Guarantors; provided, however that with respect to the Ohio Guarantors, we will be relying solely upon their respective Certificates of Good Standing described above);

(iv) the genuineness of all signatures;

(v) the authenticity of all documents submitted to us as originals, and the conformity to the originals of all documents submitted to us as certified, conformed, photostatic or telefacsimile copies;

(vi) with respect to all documents examined by us which contained facsimile signatures, that such signatures were the original signature of the party and have the same force and effect as an original signature;

(vii) that with respect to all documents described herein which have been executed by parties other than the Ohio Guarantors, all such parties had the power to enter into and perform all obligations thereunder, that all such other parties were duly authorized by all requisite action to execute, deliver and perform their respective obligations thereunder, that all signatories on all such documents were duly qualified and incumbent parties with the proper authority to execute all such documents, and the due execution and delivery of all such documents and the validity, enforceability and binding effect of all such documents on such other parties; and

(viii) there have been no undisclosed modifications of any provision of any document reviewed by us in connection with the rendering of this opinion and no undisclosed prior waiver of any right or any remedy contained in any of such documents.

This opinion is given solely as of the date hereof. We express no opinion as to future amendments of the Indentures or as to the effect of any other future events.

Based on the foregoing examination, and subject to and relying on the assumptions and other matters referred to above (and subject to the limitations and qualifications contained herein), we are of the opinion that:
