For purposes of this opinion, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals and the conformity to the originals of all documents submitted to us as copies. We have also assumed the authority of all persons signing all documents in connection with this opinion other than the Mississippi Guarantors and the due authorization, execution and delivery of all documents by the parties thereto other than the Mississippi Guarantors. As to various facts material to the opinions set forth herein, we have relied upon statements and representations made by the officers and other representatives of the Company and the Mississippi Guarantors, which facts we have not independently verified.

The opinions set forth herein are limited to the law of the State of Mississippi (the “State”) and the applicable federal law of the United States, and we express no opinion herein as to the law of any other jurisdiction.

In rendering the opinions expressed herein, we have assumed, without inquiry or investigation, that there has been no mutual mistake of fact or misunderstanding, fraud, duress, or undue influence involved with respect to any party and that each party has complied with any requirement of good faith, fair dealing and conscionability.

For purpose of this opinion, we have also assumed that:

4. The Indenture has been duly qualified under the Trust Indenture Act of 1939, as amended; and

5. The Company and the Mississippi Guarantors will have obtained any legally required consents, approvals, authorizations and other orders of the Commission and any other federal regulatory agencies necessary for the Exchange Notes to be exchanged, offered and sold in the manner stated in the Registration Statement and any applicable prospectus supplement.

Based upon and subject to the foregoing, we are of the opinion that:

1. Each of the Mississippi Guarantors has been duly incorporated and is validly existing as a corporation in good standing under the laws of the State of Mississippi. Our opinions in this Section 1 are based solely upon our examination of a Certificate of Existence of each of the Mississippi Subsidiaries issued by the Secretary of State of Mississippi dated October 3, 2011 and are limited to the meaning ascribed to such certificates by the said Secretary of State.

2. Each of the Mississippi Guarantors has the corporate power and authority to enter into and perform its obligations under the Indenture and respective Guarantee.

3. Each Mississippi Guarantor has taken all necessary corporate action to authorize the execution of the Indenture and its respective Guarantee.

4. The execution and delivery by each of the Mississippi Guarantors of the Indenture and its respective Guarantee do not, and the performance by the Mississippi Guarantors of their obligations thereunder will not, conflict with or constitute a breach of or default under (or an event which with notice or the passage of time or both would constitute a default under) or violation of any of (i) the respective articles of incorporation or bylaws of the Mississippi Guarantors or (ii) any statute or governmental rule or regulation of the State which is binding upon a Mississippi Guarantor.

5. Under existing provisions of law, no authorization, approval, consent, order, filing or registration of or from any governmental or regulatory body in the State was required in connection with the execution and delivery of the Indenture by the Mississippi Guarantors or is required for the issuance by the Mississippi Guarantors of the Guarantees.
