In rendering this opinion, we have assumed that:

(a) The Indenture has been executed and delivered by the signatories thereof prior to the release and acceptance of this opinion letter, and in substantially identical form as the form sent to us for review;

(b) all documents submitted to us as originals are authentic, true, accurate and complete; and

(c) the documents submitted to us as copies conform to the originals of such documents which are themselves authentic, true, accurate and complete.

In making our examination of documents executed by parties other than Utah Guarantor: (i) we have assumed that each such party has satisfied those legal requirements that are applicable to it to the extent necessary to make such documents enforceable against it, including, without limitation, due authorization by all requisite action, corporate or other, and due execution; and, (ii) we have assumed the delivery, validity and binding effect thereof upon such parties.

As to certain factual matters material to the opinions expressed herein, we have relied, without investigation or independent verification, with your consent, upon certain certificates, statements and representations of officers and other representatives of Utah Guarantor and filed certificates issued by governmental officials, offices or agencies.

Although we have reviewed the Indenture and have made such inquiries as we have deemed appropriate under the circumstances, we have, with your consent, not verified independently the existence or absence of all the facts set forth in the Indenture and documents and agreements ancillary thereto.

Based upon the foregoing, and under applicable Utah law in effect on the date of this opinion, we are of the opinion that:

1. Based on the Utah Guarantor Certificate of Existence, Utah Guarantor is a limited liability company, validly existing and in good standing under the laws of the State of Utah.

2. Utah Guarantor has all necessary power and authority as a limited liability company to execute and deliver the Indenture and to perform its obligations thereunder. The Indenture has been duly executed and delivered by Utah Guarantor and the performance by Utah Guarantor of its obligations thereunder have been duly authorized by all necessary company action on the part of Utah Guarantor.

3. The execution and delivery by Utah Guarantor of the Indenture, and the consummation of the transactions contemplated therein, do not: (a) violate or result in a breach of or default under Utah Guarantor’s Authority Documents; or (b) conflict with or violate any Utah law, rule, regulation or ordinance applicable to Utah Guarantor.

4. No additional authorizations, consents, licenses or approvals are required for the Utah Guarantor’s entry into the Indenture and performance of the Indenture, and no additional authorizations are required for the Utah Guarantor to execute, enter into or perform its obligations under the Indenture.

The foregoing opinions are subject to the following qualifications and limitations, in addition to those stated elsewhere in this letter:

A. We express no opinion as to the legal enforceability of the Indenture, nor respecting compliance with any requirement of Utah or federal securities laws that may arise from the Indenture or the transactions contemplated therein.

B. We express no opinion herein as to the laws of any jurisdiction other than Utah. We express no opinion as to, and assume compliance with, any applicable federal or state securities laws. Our duties and responsibilities with respect to this opinion letter shall at all times and in all respects be governed by and construed in accordance with the internal laws of the State of Utah.

C. In rendering the opinions herein, we call attention to the fact that, although we have acted as special Utah counsel to Utah Guarantor in connection with this transaction, our engagement has been limited to specific matters about which we have been consulted, and there may be matters of a legal nature involving Utah Guarantor about which we have not been consulted and in connection with which we have not represented Utah Guarantor.

This opinion is rendered as of the effective date set forth above, and we express no opinion as to circumstances or events which may occur subsequent to such date. We understand that you will rely as to matters of Utah law, as applicable, upon this opinion in connection with the matters set forth herein. In addition, we understand that Debevoise & Plimpton LLP (“Debevoise”) will rely as to matters of Utah law, as applicable, upon this opinion in connection with an opinion to be rendered by it on the date hereof relating to the Company. In connection with the foregoing, we hereby consent to your and Debevoise’s relying as to matters of Utah law, as applicable, upon this opinion.

We consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference to our firm under the heading “Validity of the Securities” in the Prospectus. In giving such consent, we do not hereby concede that we are within the category of persons whose consent is required under Section 7 of the Act or the rules and regulations of the U.S. Securities and Exchange Commission thereunder.
