In rendering the opinions set forth below, we have assumed and have not verified (i) the genuineness of the signatures on all documents that we have examined, (ii) the legal capacity of all natural persons, (iii) the authenticity of all documents supplied to us as originals, (iv) the conformity to the authentic originals of all documents supplied to us as certified, photostatic or faxed copies, (v) the authenticity of the originals of such latter documents and (vi) that the Registration Statement, and any amendments thereto (including post-effective amendments), will have become effective and the Exchange Notes will be issued in compliance with applicable federal and state securities laws and in the manner described in the Registration Statement. In conducting our examination of documents, we have assumed the power, corporate or other, of all parties thereto other than the Issuers to enter into and perform all obligations thereunder and have also assumed the due authorization by all requisite action, corporate or other, and the due execution and delivery by such parties of such documents and that, except as set forth in the opining paragraphs below, to the extent such documents purport to constitute agreements, such documents constitute valid and binding obligations of such parties.

        Based upon and subject to the foregoing and the limitations, qualifications, exceptions and assumptions set forth herein, we are of the opinion that:

2.

When the 2019 Exchange Notes (in the form examined by us) have been duly executed by the Issuers, authenticated by the Trustee in accordance with the terms of the 2019 Notes Indenture and issued and delivered upon consummation of the 2019 Notes Exchange Offer against receipt of Original 2019 Notes surrendered in exchange therefor in accordance with the terms of the 2019 Notes Exchange Offer, the 2019 Registration Rights Agreement and the 2019 Notes Indenture, (1) the 2019 Exchange Notes will constitute valid and legally binding obligations of the Issuers and (2) the 2019 Guarantees will constitute valid and legally binding obligations of the Guarantors.

Furthermore, (a) we express no opinion regarding the validity or effect of any provision purporting to establish any obligation of any party as absolute or unconditional regardless of the occurrence or non-occurrence or existence or non-existence of any event or other state of facts or purporting to limit the use of the Indenture in

We also consent to the reference to our firm under the caption "Legal Matters" in the Registration Statement. In giving this consent, we do not thereby admit that we are included in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the SEC.
