The Indentures include the guarantees of the Notes by the Existing Guarantors and the New Guarantors (the “Guarantees”).

In arriving at the opinions expressed below, we have reviewed executed copies of the Indentures.

In addition, we have reviewed the originals or copies certified or otherwise identified to our satisfaction of all such corporate records of the New Guarantors and such other documents, and we have made such investigations of law, as we have deemed appropriate as a basis for the opinions expressed below.

In rendering the opinions expressed below, we have assumed the authenticity of all documents submitted to us as originals and the conformity to the originals of all documents submitted to us as copies. In addition, we have assumed and have not verified the accuracy as to factual matters of each document we have reviewed.

Based on the foregoing, and subject to the further assumptions and qualifications set forth below, it is our opinion that the Guarantees are the valid, binding and enforceable obligations of the New Guarantors, entitled to the benefits of the respective Indenture.

Insofar as the foregoing opinions relate to the validity, binding effect or enforceability of any agreement or obligation of the New Guarantors, (x) we have assumed that such New Guarantor and each other party to such agreement or obligation has satisfied those legal requirements that are applicable to it to the extent necessary to make such agreement or obligation enforceable against it (except that no such assumption is made as to any of the New Guarantors regarding matters of the federal law of the United States of America, the law of the State of New York , the General Corporation Law of the State of Delaware and the Limited Liability Company Act of the State of Delaware that in our experience normally would be applicable to general business entities with respect to such agreement or obligation) and (y) such opinion is subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally and to general principles of equity. In addition, the enforceability of indemnification provisions may be subject to public policy considerations.

The foregoing opinions are limited to the federal law of the United States of America, the law of the State of New York, the General Corporation Law of the State of Delaware and the Limited Liability Company Act of the State of Delaware.

We hereby consent to the filing of this opinion as Exhibit 5.5 to the Registration Statement and to the reference to this firm in the Registration Statement and the related prospectus under the caption “Legal Matters.” In giving this consent, we do not thereby admit that we are experts with respect to any part of the Registration Statement, including this Exhibit, within the meaning of the term “expert” as used in the Securities Act or the rules and regulations of the Commission issued thereunder. The opinions expressed herein are rendered on and as of the date hereof, and we assume no obligation to advise you or any other person, or to make any investigations, as to any legal developments or factual matters arising subsequent to the date hereof that might affect the opinions expressed herein.

Very truly yours,
CLEARY, GOTTLIEB, STEEN & HAMILTON
