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, that all copies of documents submitted to us conform to the originals, and that the Exchange Notes have been duly authenticated by the Trustee for the Exchange Notes as provided in the Indenture for the Exchange Notes. We have assumed that each of the Company, the Note Guarantors, and the Trustee is duly organized, validly existing, and in good standing under the laws of its jurisdiction of incorporation. We have relied as to certain matters on information obtained from public officials, officers of the Company, and other sources believed by us to be responsible. Based upon the foregoing, and subject to the qualifications set forth herein, we are of the opinion that the Securities constitute the valid and binding obligations of the Company and the Note Guarantors, respectively, enforceable against the Company and the Note Guarantors 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. The foregoing opinion is subject to the qualifications that we express no opinion as to (i) waivers of defenses or statutory or constitutional rights or waivers of unmatured claims or rights, (ii) rights to indemnification, contribution or exculpation to the extent that they purport to indemnify any party against, or release or limit any party's liability for, its own breach or failure to comply with statutory obligations, or to the extent such provisions are contrary to public policy, or (iii) rights to collection or liquidated damages or penalties on overdue or defaulted obligations. We are members of the bar of the State of New York. We do not purport to be experts in, and do not express any opinion on, any laws other than the law of the State of New York, the Delaware General Corporation Law and the Federal law of the United States of America. We hereby consent to the filing of this opinion as Exhibit 5.1 to the Registration Statement and to the reference to our firm under the heading "Legal Matters" in the Prospectus contained in the Registration Statement. In giving such consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act. Very truly yours, /s/ Covington & Burling Covington & Burling
