Based on the foregoing and on such legal considerations as we deem relevant, we are of the opinion that (a) the Notes constitute valid and legally binding obligations of the Company, enforceable against the Company in accordance with their terms, except as the enforceability thereof is subject to the effect of (i) bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer or conveyance or other similar laws relating to or affecting creditors’ rights generally, (ii) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law) or (iii) any implied covenants of good faith and fair dealing (collectively, the “Enforceability Exceptions”) and (b) the Guarantee constitutes a valid and legally binding obligation of the Guarantor, enforceable against the Guarantor in accordance with its terms, except as the enforceability thereof is subject to the effect of the Enforceability Exceptions.

The opinions set forth above are limited in all respects to matters of the laws of the State of New York, the Delaware LLC Act, the Delaware Revised Uniform Limited Partnership Act and applicable reported judicial decisions, rules and regulations interpreting and implementing those laws, and the federal laws of the United States of America, in each case as in effect on the date hereof. We express no opinion as to the effect of the laws of any other jurisdiction.
