The issuance of the Initial Notes, the Guarantees in respect of the Initial Notes (collectively, the “Initial Guarantees”) and the Series B Preferred Stock (collectively, the “Initial Securities”) is subject to certain conditions set forth under the caption “The Exchange Offer—Conditions to the Exchange Offer” (the “Closing Conditions”) in the prospectus forming a part of the Registration Statement (the “Prospectus”). In the event the Closing Conditions are satisfied or waived in accordance with the terms of the Prospectus, the Series A Notes and Guarantees in respect of the Series A Notes will be issued pursuant to an indenture (the “Series A Indenture”) dated as of the closing date of the exchange offer as described in the Prospectus (the “Closing Date”) by and among the Company, the Guarantors and U.S. Bank National Association, as trustee (the “Trustee”), the Series B Notes and Guarantees in respect of the Series B Notes will be issued pursuant to an indenture dated as of the Closing Date by and among the Company, the Guarantors and the Trustee (the “Series B Indenture” and together with the Series A Indenture, the “Indentures”), and the Series B Preferred Stock will be issued pursuant to a certificate of designations (the “Certificate of Designations,” together with the Indentures, the “Transaction Documents”) filed with the Secretary of State of Delaware on or before the Closing Date.

Pursuant to the Registration Statement, the Company has offered to exchange claims (the “Exchange Offer”) under the Company’s existing credit agreement (i) with respect to outstanding letters of credit issued under the revolving credit facility (the “LC claims”), (ii) with respect to the outstanding principal amount of term loans, (iii) with respect to the outstanding principal amount of loans issued under the revolving credit facility and (iv) with respect to deferred interest and fees due and outstanding (collectively, the “credit agreement claims”). If the Exchange Offer is consummated, the credit agreement claims will be exchanged for a combination of (A) approximately 3,717,948 shares of Series B Preferred Stock, (B) $140.0 million in aggregate principal amount of Series A Notes, to be allocated among all holders of credit agreement claims other than LC claims on a pro rata basis and (C) subscription rights to all eligible holders of credit agreement claims to purchase for cash on a pro rata basis (subject to oversubscription rights) up to $100.0 million in aggregate principal amount of Series B Notes.

Capitalized terms not otherwise defined herein shall have the same meanings attributed to such terms in the Registration Statement.

You have requested our opinion concerning the discussion set forth in the section entitled “MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS” in the Registration Statement. In providing this opinion, we have assumed (without any independent investigation or review thereof) that:

b. All factual representations, warranties and statements made or agreed to by the parties to the Registration Statement, and other documents relating to the Exchange Offer, are true and accurate as of the date hereof; and

c. The description of the Exchange Offer in the Registration Statement is accurate, the Exchange Offer will be consummated in accordance with such description, without any waiver or breach of any material provision thereof, and the Exchange Offer will be effective under applicable corporate law.

This opinion is based on current provisions of the United States Internal Revenue Code of 1986 (the “Code”), the United States Treasury regulations promulgated thereunder, and the interpretation of the Code and such regulations by the courts and the Internal Revenue Service, as they are in effect and exist at the date of this opinion. It should be noted that statutes, regulations, judicial decisions and administrative interpretations are subject to change at any time and, in some circumstances, with retroactive effect. A material change that is made after the date hereof in any of the foregoing bases for our opinion could adversely affect our conclusion.

Based upon the foregoing, we confirm that the statements set forth in the Prospectus under the heading “MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS,” insofar as they address the consequences of the Exchange Offer to U.S. holders and Non-U.S. holders and discuss matters of U.S. federal tax law and regulations or legal conclusions with respect thereto, and except to the extent stated otherwise therein, are our opinion, subject to the assumptions, qualifications and limitations stated herein and therein.
