We have also examined and relied upon originals or copies, certified or otherwise identified to our satisfaction, of such records, documents, certificates and other instruments as in our judgment are necessary or appropriate in order to express the opinions hereinafter set forth. As to factual matters, we have assumed the correctness of and relied upon the recitals, statements, representations and warranties of the parties contained in the Indentures and in certificates provided pursuant to or in connection with the Indentures or otherwise provided to us, and we have made no independent inquiries or investigations. For purposes of the opinions on the existence and good standings of the Tennessee Guarantors, we have relied solely upon the certificates of existence issued by the Tennessee Secretary of State on July 2, 2012 and July 3, 2012 for IXT and EDI, respectively.

In making such examination and in expressing our opinions, we have further assumed, without investigation or inquiry:

(a) the due organization and existence of all parties to the Indentures, except to the extent that we express an opinion in Paragraph 1 below regarding the existence of each of the Tennessee Guarantors,

(b) the due execution and delivery of the Indentures by the parties thereto, in substantially the form submitted to us, duly completed in a full, accurate and consistent manner, except to the extent that we express an opinion in Paragraph 3 below regarding the execution and delivery of the Indentures by each of the Tennessee Guarantors,

(c) the due authorization of the Indentures by all parties thereto, except to the extent that we express an opinion in Paragraph 4 below regarding the authorization of the Indentures by each of the Tennessee Guarantors,

(d) that each of the parties to the Indentures has the legal right, power and authority to enter into the Indentures and to consummate the transactions contemplated thereby, except to the extent that we express an opinion in Paragraph 2 below regarding the power and authority of each of the Tennessee Guarantors,

(e) that all signatures on any executed documents furnished to us are genuine, all original documents submitted to us are authentic originals and all certified or other reproductions of documents submitted to us conform to the original documents, and

(f) that the Indentures have been put out of the possession of each of the Tennessee Guarantors and into the possession of an authorized representative of the other party or parties thereto with the intent to create immediately binding contractual obligations.
