In rendering the opinions expressed below, (a) we have examined and relied on the originals, or copies certified or otherwise identified to our satisfaction, of such agreements, documents and records of the Issuers, the Guarantors and their respective parents and subsidiaries and such other instruments and certificates of public officials, officers and representatives of the Issuers, the Guarantors and their respective parents and subsidiaries and others as we have deemed necessary or appropriate for the purposes of such opinions, (b) we have examined and relied as to factual matters upon, and have assumed the accuracy of, the statements made in the certificates of public officials, officers and representatives of the Issuers, the Guarantors and their respective parents and subsidiaries and others delivered to us and (c) we have made such investigations of law as we have deemed necessary or appropriate as a basis for such opinions.

In rendering the opinions expressed below, we have assumed, with your permission, without independent investigation or inquiry, (i) the authenticity and completeness of all documents submitted to us as originals, (ii) the genuineness of all signatures on all documents that we examined, (iii) the conformity to authentic originals and completeness of documents submitted to us as certified, conformed or reproduction copies, (iv) the legal capacity of all natural persons executing documents, (v) the power and authority of the Trustee to enter into and perform its obligations under the Indenture, (vi) the due authorization, execution and delivery of the Indenture by the Trustee, (vii) the enforceability of the Indenture against the Trustee, (viii) the power and authority of the Collateral Agents to enter into and perform their obligations under the Indenture, (ix) the due authorization, execution and delivery of the Indenture by the Collateral Agents, (x) the enforceability of the Indenture against the Collateral Agents and (xi) that each of the Lux Issuer, the LLC Issuer and the Other Guarantors (A) has been duly organized under the laws of the jurisdiction of its formation, (B) is validly existing and in good standing under the laws of the jurisdiction of its formation, (C) has the power and authority to execute, deliver and perform its obligations under the Indenture, (D) has taken all necessary actions under the laws of the jurisdiction of its formation to duly authorize the execution and delivery of, and performance of its obligations under the Indenture and (E) to the extent governed by the laws of the jurisdiction of its formation, has duly executed and delivered the Indenture.

Based upon and subject to the foregoing and the qualifications and limitations hereinafter set forth, we are of the opinion that, upon the due execution and issuance of the New Notes by the Issuers and authentication of the New Notes by the Trustee in accordance with the Indenture and delivery of the New Notes against exchange therefor of the Old Notes, pursuant to the exchange offer described in the Registration Statement, (1) the New Notes will constitute valid and binding obligations of the Issuers, enforceable against the Issuers in accordance with their terms, and (2) the Guarantees will constitute valid and binding obligations of the Guarantors, enforceable against the Guarantors in accordance with their terms.
