In our examination of the aforesaid documents, we have assumed the genuineness of all signatures, the legal capacity of all natural persons, the accuracy and completeness of all documents submitted to us, the authenticity of all original documents, and the conformity to authentic original documents of all documents submitted to us as copies (including telecopies). We have assumed that (i) each of the parties to the Indenture (other than the Company) has all requisite power and authority under all applicable laws, regulations and governing documents to execute, deliver and perform its obligations under the Transaction Documents, as applicable, (ii) each of the parties to the Indenture (other than the Company) has duly authorized, executed and delivered the Transaction Documents, as applicable, (iii) each of the parties to the Indenture (other than the Company) is duly organized, validly existing, and in good standing in all necessary jurisdictions, (iv) the Indenture constitutes a valid and binding obligation, enforceable against all parties thereto (other than the Company, as applicable) in accordance with its terms, (v) there has been no material mutual mistake of fact or misunderstanding or fraud, duress or undue influence in connection with the negotiation, execution or delivery of the Indenture, and (vi) there are and have been no agreements or understandings among the parties, written or oral, and there is and has been no usage of trade or course of prior dealing among the parties that would, in either case, define, supplement or qualify the terms of the Indenture or the Exchange Notes. This opinion letter is given, and all statements herein are made, in the context of the foregoing.

This opinion letter is based as to matters of law solely on the applicable provisions of (i) the Delaware General Corporation Law, as amended, and (ii) the law of the State of New York, (but not including any statutes, ordinances, administrative decisions, rules or regulations of any political subdivision of the State of New York). We express no opinion herein as to any other laws, statutes, ordinances, rules, or regulations. As used herein, the terms “Delaware General Corporation Law, as amended” and “the law of the State of New York” include the statutory provisions contained therein, all applicable provisions of the Delaware and New York Constitutions and reported judicial decisions interpreting these laws. With respect to clause (ii) above, the opinion expressed herein is based on a review of those laws that, in our experience, are generally recognized as applicable to the transactions contemplated in the Documents.

Based upon, subject to and limited by the foregoing, we are of the opinion that following (i) the effectiveness of the Registration Statement, (ii) due delivery to the Company of the Original Notes in exchange for the Exchange Notes as specified in the Registration Rights Agreement, and (iii) due execution, authentication, issuance and delivery of the Exchange Notes as provided in the Indenture, the Exchange Notes will constitute legal and binding obligations of the Company.

In addition to the qualifications, exceptions and limitations elsewhere set forth in this opinion letter, our opinion expressed above is also subject to the effect of: (i) bankruptcy, insolvency, reorganization, receivership, moratorium or other laws affecting creditors’ rights (including, without limitation, the effect of statutory and other

This opinion letter has been prepared for your use in connection with the Registration Statement and speaks as of the date hereof. We assume no obligation to advise you of any changes in the foregoing subsequent to the delivery of this opinion letter.

We hereby consent to the filing of this opinion letter as an exhibit to the Registration Statement and to the reference to this firm under the caption “Legal Matters” in the prospectus constituting a part of the Registration Statement.
