Dear Ladies and Gentlemen:

Re:    Centennial Gas Liquids ULC

We have acted as special Alberta counsel to Centennial Gas Liquids ULC, an Alberta unlimited liability corporation (the Alberta Guarantor), in connection with the guarantee by the Alberta Guarantor of certain obligations of NGL Energy Partners LP (the Partnership) and NGL Energy Finance Corp. (the Co-Issuer and together with the Partnership, the Issuers), under their 6.875% Senior Notes due 2021 (the 2021 Exchange Notes) and their 5.125% Senior Notes due 2019 (the 2019 Exchange Notes and together with the 2021 Exchange Notes, the Exchange Notes). The 2021 Exchange Notes are to be issued pursuant to an exchange offer (the 2021 Notes Exchange Offer) in exchange for a like principal amount of the issued and outstanding 6.875% Senior Notes due 2021 (the Old 2021 Notes). The Old 2021 Notes are, and the 2021 Exchange Notes will be, governed by the indenture dated as of October 16, 2013 (the Indenture), by and among, inter alios, the Partnership, the Co-Issuer, the Alberta Guarantor and U.S. Bank National Association, as trustee (the Trustee), as amended and supplemented by the First Supplemental Indenture thereto dated as of December 2, 2013 among the Issuers, the subsidiaries of the Partnership party thereto and the Trustee, and the Second Supplemental Indenture thereto dated as of April 22, 2014 among the Issuers, the subsidiaries of the Partnership party thereto and the Trustee (such indenture, as so amended and supplemented, being referred to herein as the 2021 Notes Indenture). The Old 2019 Notes are, and the 2019 Exchange Notes will be, governed by the indenture dated as of July 9, 2014 (the 2019 Notes Indenture and, together with the 2021 Notes Indenture, the Indentures) among the Issuers, the subsidiaries of the Partnership party thereto and the Trustee.
