We are opining herein solely as to the state laws of the State of New Hampshire. To the extent that the laws of any other jurisdiction govern the matters as to which we are opining herein, we have assumed, with your permission and without independent investigation, that such laws are identical to the state laws of the State of New Hampshire, and we express no opinion as to whether such assumption is reasonable or correct. For purposes of our opinions expressed below, we have assumed that the facts and law governing the future performance of the New Hampshire Guarantors of their respective obligations under the Transaction Documents will be identical to the facts and law governing their performance on the date of this opinion.

Based upon and subject to the foregoing, we are of the opinion that:

1. Each of C.H.P., C.H.R. and DJB is a limited liability company, validly existing and in good standing under the laws of the State of New Hampshire.

2. The execution, delivery and performance of the Transaction Documents by the New Hampshire Guarantors have been duly authorized by all requisite limited liability company action on behalf of the New Hampshire Guarantors, and the Fifth Supplemental Indenture has been duly executed and delivered by the New Hampshire Guarantors.

3. The execution and delivery by the New Hampshire Guarantors of the Transaction Documents and the consummation by the New Hampshire Guarantors of the transactions contemplated thereby do not violate the provisions of the applicable New Hampshire Guarantor’s Organizational Documents.

This opinion is provided as a legal opinion only, and not as a guaranty or warranty of the matters discussed herein. Please note that we are opining only as to the matters expressly set forth herein, and no opinion should be inferred as to other matters. This opinion is based upon currently existing statutes, rules, regulations and judicial decisions and is rendered as of the date hereof, and we disclaim any obligation to advise you of any change in any of the foregoing sources of law or subsequent developments in law or changes in facts and circumstances which might affect any matters or opinions set forth herein.

We hereby consent to the filing of this opinion with the Commission as an exhibit to the Company’s Current Report on Form 8-K to be filed on or about October 10, 2014 in accordance with the requirements of Rule 601(b)(5) of Regulation S-K under the Securities Act and to the use of our name therein and in the Prospectus Supplement under the caption “Legal Matters.” In giving such consent, we do not hereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission.

Very truly yours,
