To the extent it may be relevant to the opinions expressed herein, we have assumed that (i) all of the parties to the Documents (other than the Company and the DE/NY Guarantors) are validly existing and in good standing under the laws of their respective jurisdictions of organization; (ii) the parties to the Documents (other than the Company and the DE/NY Guarantors) have the power and authority to (a) execute and deliver the Documents, (b) perform their obligations thereunder and (c) consummate the transactions contemplated thereby; (iii) each of the Documents has been duly authorized, executed and delivered by each of the parties thereto (other than the Company and the DE/NY Guarantors), (iv) each of the Documents constitutes a valid and binding obligation of all of the parties thereto (other than as expressly addressed in the opinions below as to the Company and the Guarantors), enforceable against such parties in accordance with their respective terms; (v) all of the parties to the Documents will comply with all of their obligations under the Documents and all laws applicable thereto; (vi) the Exchange Notes will be duly authenticated and delivered by the Trustee in accordance with the terms of the Indentures, against receipt of the Original Notes surrendered in exchange therefor; and (vii) the Exchange Notes and the notations of guarantee evidencing the Exchange Note Guarantees will conform to the specimens thereof examined by us.

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

1. The Exchange Notes, when executed, issued and delivered by the Company in accordance with the terms of the Indentures in exchange for the Original Notes in the manner contemplated by the Registration Statement, will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms.

2. The Exchange Note Guarantees, when the Exchange Notes have been duly executed, issued and delivered in accordance with the terms of the Indentures in exchange for the Original Notes in the manner contemplated by the Registration Statement, will constitute valid and binding obligations of each of the Guarantors, enforceable against the Guarantors in accordance with their terms.

We express no opinion as to the validity, binding effect or enforceability of any provision of any of the Documents:

(i) relating to indemnification, contribution or exculpation;

(ii) containing any purported waiver, release, variation of rights, disclaimer, consent or other agreement of similar effect (all of the foregoing, collectively, a “Waiver”) by the Company or the Guarantors under any of such Documents to the extent limited by provisions of applicable law (including judicial decisions), or to the extent that such a Waiver applies to a right, claim, duty, defense or ground for discharge otherwise existing or occurring as a matter of law (including judicial decisions);

(iii) related to (a) forum selection or submission to jurisdiction (including, without limitation, any waiver of any objection to venue in any court or of any objection that a court is an inconvenient forum) to the extent that the validity or binding effect of such provision is to be considered by any court other than a court of the State of New York, (b) choice of governing law to the extent that the validity or binding effect of any such provision is to be considered by any court other than a court of the State of New York or a federal district court sitting in the State of New York and applying the law of the State of New York, in each case, applying the choice of law principles of the State of New York, (c) service of process or (d) waiver of any rights to trial by jury;

(iv) specifying that provisions thereof may be modified or waived only in writing;

(v) purporting to give any person or entity the power to accelerate obligations without any notice to the obligor;

(vi) specifying that any person may exercise set-off or similar rights other than in accordance with applicable law;

(vii) relating to payment of late charges, interest (or discount or equivalent amounts), premium, “make-whole” payments, collection costs or fees at a rate or in an amount, after or upon the maturity or acceleration of the liabilities evidenced or secured thereby or after or during the continuance of any default or other circumstance, or upon prepayment, that a court would determine in the circumstances to be unreasonable, a penalty or a forfeiture; or

(viii) requiring that any unearned portion of the Original Notes or Exchange Notes issued at a discount be paid upon acceleration or otherwise earlier than the stated final maturity.

We express no opinion as to the effect of any law of any jurisdiction other than the State of New York wherein any party to the Documents may be located or wherein enforcement of any Documents may be sought that limits the rates of interest legally chargeable or collectible.

We express no opinion as to any agreement, instrument or other document (including any agreement, instrument or other document referred to, or incorporated by reference in, the Documents) other than the Documents.

The opinion set forth above is subject to the following qualifications:

A. The opinion is subject to:

(i) bankruptcy, insolvency, reorganization, moratorium and other laws (or related judicial doctrines) now or hereafter in effect relating to or affecting creditors’ rights or remedies generally;

(ii) general principles of equity (including, without limitation, standards of materiality, good faith, fair dealing and reasonableness, equitable defenses and limits as to the availability of equitable remedies) whether such principles are considered in a proceeding in equity or at law; and

(iii) the application of any applicable fraudulent conveyance, fraudulent transfer, fraudulent obligation, or preferential transfer law or any law governing the distribution of assets of any person now or hereafter in effect affecting creditors’ rights and remedies generally.

B. Provisions in the Indentures that provide that the Guarantors’ liability thereunder shall not be affected by (i) actions or failures to act on the part of the holders or the Trustee, (ii) amendments or waivers of provisions of documents governing the guaranteed obligations or (iii) other actions, events or circumstances that make more burdensome or otherwise change the obligations and liabilities of the Guarantors, might not be enforceable under circumstances and in the event of actions that change the essential nature of the terms and conditions of the guaranteed obligations.  With respect to each Guarantor, we have assumed that consideration that is sufficient to support the agreements of each Guarantor under the Documents has been received by each Guarantor.

The opinions expressed herein are limited to the laws of the State of New York and to the extent relevant to the opinions expressed herein, the General Corporation Law of the State of Delaware, the Limited Liability Company Act of the State of Delaware and the Revised Uniform Limited Partnership Act of the state of Delaware, each as currently in effect, and no opinion is expressed with respect to any other laws or any effect that such other laws may have on the opinions expressed herein.  This opinion letter is limited to the matters stated herein, and no opinion is implied or may be inferred beyond the matters expressly stated herein.  This letter is given only as of the time of the effectiveness of the Registration Statement, and we undertake no responsibility to update or supplement this letter after such time.
