On June 25, 2010, Butane Acquisition I LLC, a Delaware limited liability company (“Buyer”) and wholly-owned indirect subsidiary of Sunoco Logistics Partners L.P. (the “Partnership”) entered into a definitive Asset and Membership Interest Purchase and Sale Agreement (the “Purchase Agreement”) with Texon Distributing L.P. (“Texon”) to acquire Texon’s butane blending business for approximately $140 million plus inventory. The business includes certain intellectual property, customer contracts, butane inventories and related assets. The acquired intellectual property includes patents and associated software and other intellectual property rights relating to butane blending technology.

The Purchase Agreement contains representations and warranties, covenants, indemnifications, and closing conditions that are customary for a transaction of this type.

The transaction has received early termination of the Hart-Scott-Rodino waiting period and is expected to close in the early third quarter 2010.

This acquisition is expected to be funded with $100 million debt financing from Sunoco, Inc. under a three-year note at an interest rate of three-month LIBOR plus 275 basis points per annum, with the remainder funded under the Partnership’s revolving credit facility.

The description of the Purchase Agreement herein is qualified in its entirety by the document itself, which will be filed as an exhibit to the Partnership’s Quarterly Report on Form 10-Q for the quarter ended June 30, 2010.

On June 28, 2010, the Partnership issued a press release announcing the signing of the Purchase Agreement. Additional information concerning the transaction was presented to investors in a teleconference call on June 29, 2010. A copy of the press release is attached as Exhibit 99.1, a copy of the slide presentation is attached as Exhibit 99.2, and both are incorporated herein by reference.
