ENERGY TRANSFER AFFILIATES TO MOVE FORWARD WITH A GULF COAST LPG EXPORT/IMPORT PROJECT

SHELL SIGNS LONG-TERM LPG EXPORT/IMPORT AGREEMENTS

DALLAS, May 6, 2013 - Sunoco Logistics Partners L.P. (NYSE: SXL), an affiliate of Dallas-based Energy Transfer Partners, L.P. (NYSE: ETP), and Lone Star NGL LLC, a joint venture between ETP and Regency Energy Partners LP (NYSE: RGP), announced today that long-term, fee-based agreements have been executed with Shell Trading US Company (STUSCO) to move forward with a liquefied petroleum gas (LPG) export/import project. STUSCO has committed to the project, known as Mariner South, as an anchor customer.
The Mariner South project will integrate SXL's existing Nederland Marine Terminal and pipeline from Mont Belvieu, Texas to Nederland, Texas with Lone Star's Mont Belvieu fractionation and storage facilities, creating a world class LPG export/import operation in the U.S. Gulf Coast. Mariner South will have an initial capacity of 6 million barrels per month and will be designed to load LPG carriers with an approximate capacity of 550,000 barrels. The Mariner South project is expected to be operational in the first quarter of 2015.
The project will utilize Lone Star's increasing fractionation capacity at Mont Belvieu as well as construction of a new 100,000 barrel per day de-ethanizer to convert propane to international specifications. It also will involve the construction of new refrigerated storage tanks located at the Nederland Terminal to take deliveries into the LPG vessels. The Nederland Terminal will provide 24- hour ship access in the Gulf Coast with a load rate of up to 30,000 barrels per hour. The terminal facility includes existing docks and acreage for future expansion. The project can be expanded to handle additional volumes of products.
"The development of this world class Gulf Coast LPG operation is in response to continued growth in North American NGL production and international demand for LPG supplies," said Steve Spaulding, Executive Vice President of Lone Star NGL. "We are very pleased to have Shell on board as an anchor customer. The Mariner South project is a clear example of the value created from the synergies between Sunoco Logistics and Lone Star assets."
"By working together, Lone Star and Sunoco Logistics will provide an expedited solution to meet the growing customer demand for LPG exports from the Gulf Coast," said Mike Hennigan, President and Chief Executive Officer of Sunoco Logistics. "The Mariner South project builds on the Mariner project franchise we have established in the Northeast to provide comprehensive takeaway solutions for our growing customer base as a direct result of increased shale production."
