Item 1.01. Entry into a Material Definitive Agreement

On August 23, 2016, Range Resources Corporation, a Delaware corporation (“Range”), entered into the following agreements with the applicable indenture trustee:

• a supplemental indenture (the “2021 Supplemental Indenture”) to the Indenture, dated as of May 25, 2011, by and among Range, the guarantors party thereto, and The Bank of New York Mellon Trust Company, N.A., as trustee, governing Range’s 5.75% senior subordinated notes due 2021.

• a supplemental indenture (the “2022 Supplemental Indenture”) to the Indenture, dated as of March 9, 2012, by and among Range, the guarantors party thereto, and The Bank of New York Mellon Trust Company, N.A., as trustee, governing Range’s 5.00% senior subordinated notes due 2022.

• a supplemental indenture (the “2023 Supplemental Indenture” and, together with the 2022 Supplemental Indenture and the 2021 Supplemental Indenture, the “Supplemental Indentures”) to the Indenture, dated as of March 18, 2013, by and among Range, the guarantors party thereto, and U.S. Bank National Association, as trustee, governing Range’s 5.00% senior subordinated notes due 2023.

These Supplemental Indentures are not yet effective. The effectiveness of each of the Supplemental Indentures is conditioned upon, among other things, the consummation of the merger contemplated by the previously-disclosed Agreement and Plan of Merger, dated as of May 15, 2016 (the “Merger Agreement”), by and among Range, Memorial Resource Development Corp. (“Memorial”), and Medina Merger Sub, Inc. (“Merger Sub”). Pursuant to the Merger Agreement (and on the terms and subject to the conditions set forth in the Merger Agreement), Merger Sub would merge with and into Memorial, as a result of which Memorial would become a wholly owned subsidiary of Range (the “Merger”).

The foregoing descriptions of the Supplemental Indentures are qualified in their entirety by reference to the respective Supplemental Indentures themselves, which are each filed herewith as exhibits and incorporated by reference herein.
