Item 1.01 Entry into a Material Definitive Agreement.

As previously disclosed, on March 26, 2018, Legacy Reserves LP, a Delaware limited partnership (the “Partnership”), announced its intent to consummate a transaction that would result in the Partnership and its general partner, Legacy Reserves GP, LLC, a Delaware limited liability company (the “General Partner”), becoming subsidiaries of a newly formed Delaware corporation, Legacy Reserves Inc. (“New Legacy”), and the Partnership’s unitholders and preferred unitholders becoming common stockholders of New Legacy (such transaction referred to herein collectively as the “Corporate Reorganization”). In connection with the Corporate Reorganization, as previously disclosed on March 26, 2018, the Partnership commenced consent solicitations relating to the Partnership’s 8% Senior Notes due 2020 (the “2020 Notes”) and 6.625% Senior Notes due 2021 (the “2021 Notes”).

On April 2, 2018, following receipt of the requisite consents of the holders of the 2020 Notes and the 2021 Notes, as applicable, the Partnership entered into:

Pursuant to the Supplemental Indentures, the parties amended the Indentures to, among other things, (i) exclude the Corporate Reorganization from the definition of “Change of Control” in the Indentures, (ii) permit the Corporate Reorganization, (iii) provide for the issuance of an unconditional and irrevocable guarantee of the 2020 Notes and the 2021 Notes by New Legacy and the General Partner, (iv) provide that certain covenants and other provisions under the Indentures previously applicable to the Partnership and its restricted subsidiaries will apply to New Legacy and its restricted subsidiaries, (v) make certain changes to the restricted payments covenant to reflect that the Partnership will no longer be a publicly traded master limited partnership following the Corporate Reorganization and (vi) effect certain other conforming changes.

The foregoing descriptions of the 2020 Notes Supplemental Indenture and the 2021 Notes Supplemental Indenture do not purport to be complete and are qualified in their entirety by reference to the 2020 Notes Supplemental Indenture and the 2021 Notes Supplemental Indenture, which are filed as Exhibit 4.1 and Exhibit 4.2, respectively, to this Current Report on Form 8-K and incorporated by reference herein.
