We have also examined originals or copies, certified or otherwise identified to our satisfaction, of such records of the Company and the Subsidiary Guarantors and such agreements, certificates of officers or other representatives of the Company and the Subsidiary Guarantors and others, and such other documents, certificates and records as we have deemed necessary or appropriate as a basis for the opinions set forth herein. In rendering the opinions set forth below, we do not express any opinion as to the applicability or effect of any fraudulent transfer or similar law (i) on the issuance of the Exchange Notes and the Guarantees under the Indenture; (ii) on the related transactions contemplated thereby, or (iii) on the enforceability of any of the Indenture, the Exchange Notes or the Guarantees.

Members of our firm are admitted to the bar in the State of New York and Delaware, and we do not express any opinion as to the laws of any other jurisdiction other than the federal laws of the United States of America to the extent specifically referred to herein. Based upon the foregoing and subject to the limitations, qualifications, exceptions and assumptions set forth herein, we are of the opinion that when (i) the Registration Statement becomes effective and the Indenture has been qualified under the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"), and (ii) the Exchange Notes have been duly executed and authenticated in accordance with the terms of the Indenture and have been delivered upon consummation of the Exchange Offer against receipt of Outstanding Notes surrendered in exchange therefor in accordance with the terms of the Exchange Offer, the Exchange Notes and Guarantees will constitute valid and binding obligations of the Company and the Subsidiary Guarantors, respectively, enforceable against the Company and the Subsidiary Guarantors in accordance with their respective terms, except to the extent that the enforcement thereof may be limited by (1) bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or similar laws now or hereafter in effect relating to creditors' rights generally and (2) general principles of equity (regardless of whether enforceability is considered in a proceeding at law or in equity). We hereby consent to the filing of this opinion with the Commission as an exhibit to the Registration Statement. We also consent to the reference to our firm under the captions "Legal Matters" in the Registration Statement.
