On April 6, 2017, certain subsidiaries of Sunoco LP, a Delaware limited partnership (the “Partnership”) entered into that certain Asset Purchase Agreement (the “Purchase Agreement”), by and among Susser Petroleum Property Company LLC, a Delaware limited liability company (“PropCo”), Sunoco Retail LLC, a Pennsylvania limited liability company (“Sunoco Retail”), Stripes LLC, a Texas limited liability company (“Stripes”), Town & Country Food Stores, Inc., a Texas corporation (“Town & Country”), MACS Retail LLC, a Virginia limited liability company (“MACS,” and, together with PropCo, Sunoco Retail, Stripes and Town & Country, referred to herein collectively as “Sellers,” and each, individually, as a “Seller”), 7-Eleven, Inc., a Texas corporation (“7-Eleven”) and SEI Fuel Services, Inc., a Texas corporation and wholly-owned subsidiary of 7-Eleven (“SEI Fuel,” and, together with 7-Eleven, referred to herein collectively as “Buyers,” and each, individually, as a “Buyer”), and, solely for the purposes referenced therein, the Partnership, Sunoco Finance Corp., a Delaware corporation (“Sunoco Finance”) and Sunoco, LLC, a Delaware limited liability company (“Sunoco, LLC” and, together with the Partnership and Sunoco Finance, referred to herein collectively as “Guarantors,” and each, individually, as a “Guarantor”). Each of the Partnership and Sunoco, LLC have guaranteed Sellers’ obligations under the Purchase Agreement and related ancillary agreements pursuant to a guarantee agreement (the “Guarantee Agreement”) entered into in connection with the Purchase Agreement.

Pursuant to the Purchase Agreement, Sellers have agreed to sell a portfolio of 1,112 company-operated retail fuel outlets in 19 geographic regions, together with ancillary businesses and related assets, including the Laredo Taco Company (the “Business”), for an aggregate purchase price of $3,305,575,000, payable in cash, plus the value of inventory at the closing of the transactions contemplated by the Purchase Agreement (the “Closing”) and the assumption of certain liabilities related to the Business by Buyers. The purchase price is subject to certain adjustments, including (i) those relating to specified items that arise during post-signing due diligence and inspections and (ii) individual properties not ultimately being acquired by Buyers due to the failure to obtain necessary third party consents or waivers or because either Buyers or Sellers exercise their respective rights, under certain circumstances, to cause a specific property to be excluded from the transaction.

The Closing is expected to occur in the second half of 2017, and is subject to the satisfaction or waiver of customary closing conditions for a transaction of this type, including the receipt of any approvals required under the Hart-Scott-Rodino Antitrust Improvements Act of 1976.

The Purchase Agreement contains customary representations, warranties, agreements and other obligations of the parties. Sellers and Buyers have generally agreed to indemnify each other for breaches of the representations, warranties and covenants contained in the Purchase Agreement, subject to certain survival period limitations, deductibles, caps and mini baskets. In addition, Sellers have agreed to indemnify Buyers for certain liabilities, including certain environmental liabilities, related to Sellers’ ownership or operation of the Business prior to the date of the Closing (the “Closing Date”), and Buyers have agreed to indemnify Sellers for certain liabilities, including certain environmental liabilities.

The Purchase Agreement may be terminated by either the Sellers or Buyers under certain limited circumstances, including: (i) by Buyers and Sellers upon written agreement; (ii) by Buyers or Sellers if the Closing has not occurred by the nine month anniversary of the Signing Date, subject to certain extensions, as more particularly set forth in the Purchase Agreement; (iii) by Buyers or Sellers if any governmental entity enacts, issues or enters a final, non-appealable order that has the effect of prohibiting the transaction; (iv) by Buyers or Sellers if certain of the representations and warranties made by Sellers or Buyers, respectively, fail to be true and correct, subject to certain materiality qualifiers as more particularly set forth in the Purchase Agreement; and (v) by Buyers upon the fifth business day after a determination that certain specified diligence matters disclosed to Buyers resulted in or would reasonably be expected to result in losses to Buyers or otherwise have an objectively identifiable adverse impact to the Business with an aggregate value of greater than $50 million.

In connection with the Closing, Sellers and Buyers and their respective affiliates will enter into a number of ancillary agreements, including a fuel supply agreement between Sunoco, LLC and SEI Fuel.

The foregoing descriptions of the Purchase Agreement and the Guarantee Agreement are only summaries, do not purport to be complete, and are subject to, and qualified in their entirety by reference to the Purchase Agreement and the Guarantee Agreement, as applicable, and copies of which are filed as Exhibits 2.1 and 10.1 to this Current Report on Form 8-K and are incorporated herein by reference.
