The opinions expressed herein are limited to the laws of the State of Connecticut and I do not express any opinion herein concerning any other law. The Base Indenture provides that it is governed by the laws of the State of New York. To the extent that the opinion expressed herein relates to matters governed by the laws of the State of New York, I have relied, with their permission, as to all matters of New York law, on the opinion of Skadden, Arps, Slate, Meagher & Flom LLP dated the date hereof, which is filed herewith as Exhibit 5.3 to the Company’s Current Report on Form 8-K, and my opinion is subject to the exceptions, qualifications and assumptions contained in such opinion.

The opinions set forth below are subject to the following further qualifications, assumptions and limitations:

I have assumed that the execution and delivery by the Company of each of the Transaction Documents and the performance by the Company of its obligations thereunder do not and will not violate, conflict with or constitute a default under (i) any agreement or instrument to which the Company or any of its properties is subject, (ii) any law, rule or regulation to which the Company or any of its properties is subject (except that I do not make the assumption set forth in this clause (ii) with respect to Opined-on Law (as defined below)), (iii) any judicial or regulatory order or decree of any governmental authority or (iv) any consent, approval, license, authorization or validation of, or filing, recording or registration with any governmental authority;
