The Registration Statement relates to the proposed offers of the Issuers to exchange the 2017 Senior Notes for a like principal amount of the Issuers’ outstanding 8 ¹/4% Senior Notes due 2017 issued in a private offering on November 24, 2009 (the “Original 2017 Notes”) and to exchange the 2018 Senior Notes for a like principal amount of the Issuers’ outstanding 8 ¹/4% Senior Notes due 2018 issued in a private offering on September 23, 2010 (the “Original 2018 Notes,” and with the Original 2017 Notes, the “Original Notes”). The Original Notes were issued pursuant to two Indentures, dated in each case as of the date of the Original Notes, as supplemented, (the “Indentures”), among the Issuers, the Guarantors, and the Bank of New York Mellon, a New York banking corporation, as trustee. This opinion is rendered to you at the request of the Issuers. Capitalized terms used in this letter without definition have the meanings assigned to them in the Indentures.

In connection with this letter, we have examined executed originals or copies of executed originals of each of the following documents, each of which is dated the date hereof or as of the date hereof, unless otherwise noted (collectively, the “Offering Documents”):

6. such other documents, agreements, and instruments as we have deemed necessary or appropriate as a basis for the opinions hereafter expressed.

We have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, and the conformity to authentic original documents of all copies submitted to us as conformed, certified or reproduced copies. We have also assumed the legal capacity of natural persons.

We have assumed with respect to all parties to the Offering Documents, other than the Utah Guarantor (the “Other Parties”): (i) that each Other Party is a natural person or is an entity other than a natural person that has the corporate or other power and authority to execute and deliver the Offering Documents to which it is (or will be) a party and to consummate the transactions contemplated thereby; (ii) that each Other Party has taken all necessary corporate or

We express no opinion herein as to the laws of any jurisdiction other than the State of Utah.
