  Item 1.01 Entry Into a Material Definitive Agreement.
  On October 24, 2016, Energy Transfer Partners, L.P. ("ETP") entered into a Contribution Agreement (the "Contribution Agreement") by and among NGP X US Holdings, LP ("NGP"), PennTex Midstream Partners, LLC ("PennTex Holdco"), MRD Midstream LLC ("MRD"), WHR Midstream LLC ("WHR"), certain investors signatory thereto (collectively with NGP, PennTex Holdco, MRD and WHR, the "Contributors") and ETP. Pursuant to the terms of the Contribution Agreement, ETP has agreed to a transaction (the "Transaction") in which ETP will acquire from the Contributors all of the outstanding membership interests in PennTex Holdco (the "Holdco Interests"), which wholly owns the general partner of PennTex Midstream Partners, LP ("PTXP").  In addition, ETP has agreed to acquire the following interests in PTXP, representing an aggregate of approximately 65% of the total limited partner interests in PTXP (collectively with the Holdco Interests, the "Subject Interests"):
  •
  all of the outstanding incentive distribution rights in PTXP;
  •
  6,301,596 common units in PTXP; and
  •
  all of the 20,000,000 outstanding subordinated units in PTXP.
  PTXP owns midstream assets strategically located in the Terryville Complex in northern Louisiana that consist of a rich natural gas gathering system, two cryogenic natural gas processing plants totaling 400 million cubic feet per day of capacity, along with residue gas and natural gas liquids (NGLs) pipelines.
  ETP will acquire the Subject Interests for aggregate consideration of approximately $640 million, which will consist of approximately $320 million in cash and approximately $320 million in common units representing limited partner interests in ETP ("ETP Common Units"). The cash portion of the purchase price will be funded with a combination of proceeds from ETP Common Units recently issued under ETP's At-The-Market program and borrowings under its revolving credit facility.  The ETP Common Units to be issued as part of the consideration will be issued and sold in a private transaction exempt from registration under Section 4(a)(2) of the Securities Act of 1933, as amended. The parties expect the transaction to close in the fourth quarter of 2016, subject to customary closing conditions. There can be no assurance that all of the closing conditions will be satisfied or that the anticipated benefits of the Transaction will be realized.
  The Contribution Agreement contains customary representations, warranties, covenants, indemnification obligations and conditions to closing.  In addition, in conjunction with the transaction, Energy Transfer Equity, L.P. has agreed to waive in perpetuity its right to receive distribution in respect of its incentive distribution rights in ETP in the amount of $33 million annually.
  In conjunction with the closing of the Transaction, ETP will enter into an evaluation agreement pursuant to which it will evaluate the potential purchase of all or a portion of the remaining common units in PTXP, but will be under no obligation to do so.
  The above description of the Contribution Agreement is not complete and is qualified in its entirety by reference to the full text of the Contribution Agreement, which is filed hereto as Exhibit 2.1 and is incorporated in this Item 1.01 by reference.
  The above descriptions have been included to provide investors and security holders with information regarding the terms of the Contribution Agreement. They are not intended to provide any other factual information about ETP, the Contributors, PTXP or their respective subsidiaries, affiliates or equity holders.
