ITEM 1.01 Entry into a Material Definitive Agreement

Class A Securities Purchase Agreement and Class B Securities Purchase Agreement

On January 19, 2017, Plains Pipeline, L.P. (“Purchaser”), a Texas limited partnership and a wholly owned subsidiary of Plains All American Pipeline, L.P. (“PAA”), entered into (1) a definitive securities purchase agreement (the “Class A Agreement”) with COG Operating LLC (“Class A Seller”), a wholly owned subsidiary of Concho Resources Inc. (“Concho”), pursuant to which Purchaser will acquire all of the outstanding Class A Units of Alpha Holding Company, LLC (the “Company”), the indirect owner of the Alpha Crude Connector gathering system located in the Northern Delaware basin, as described in further detail below, and (2) a definitive securities purchase agreement (the “Class B Agreement” and, together with the Class A Agreement, the “Agreements”) with Frontier Midstream Solutions, LLC (“Class B Seller”), pursuant to which Purchaser will acquire all of the outstanding Class B Units of the Company (collectively, the “Acquisition”).  Upon the closing of the Acquisition, Purchaser will own all of the issued and outstanding equity in the Company.  The total consideration for the Acquisition is approximately $1.215 billion in cash (the “Purchase Price”), subject to adjustment based on working capital amounts as of January 1, 2017, and other routine adjustments as provided in more detail in the Class A Agreement. A cash deposit of $40 million was paid to the Class A Seller upon signing of the Class A Agreement, and the balance of the Purchase Price, as allocated between the Class A Seller and the Class B Seller, is payable in cash upon closing. Subject to clearance under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 and other customary closing conditions, the Acquisition is expected to close in the first half of 2017.  The transactions contemplated by the Class A Agreement and the Class B Agreement are expected to close contemporaneously. The Agreements include representations, warranties, covenants, indemnities, remedies, termination and other customary provisions for a transaction of this nature.

The Company indirectly owns the FERC regulated crude oil gathering system known as “Alpha Crude Connector” (the “System”) located in Eddy and Lea Counties, New Mexico and Culberson, Loving and Winkler Counties, Texas. The System is comprised of 515 miles of gathering and transmission lines and five market interconnects, including PAA’s Basin Pipeline system at Wink. Following closing, PAA intends to make three additional interconnects to PAA’s existing Northern Delaware Basin system as well as additional enhancements intended to increase the system capacity to approximately 350,000 barrels per day, depending on the level of volume at each delivery point.  The System is supported by acreage dedications covering approximately 315,000 gross acres, the majority of which have 10-year terms, and include a significant acreage dedication from Concho, one of the largest Permian Basin producers. In addition, a large area of mutual interest agreement with Concho spans the area immediately around the gathering system.
