Item 8.01 Other Events.

On May 3, 2019, Rhino Resource Partners LP (the “Partnership”), Rhino GP LLC, the Partnership’s general partner (“Rhino GP”) and Royal Energy Resources, Inc. (“Royal”), which owns 100% of the equity interests in Rhino GP, filed a complaint in the Court of Chancery in the State of Delaware against Rhino Resource Partners Holdings LLC (“Holdings”), Weston Energy LLC (“Weston”), Yorktown Partners LLC and certain Yorktown funds (collectively, the “Yorktown entities”), as well as Mr. Ronald Phillips, Mr. Bryan H. Lawrence and Mr. Bryan R. Lawrence.

The complaint alleges that Holdings violated certain representations and negative covenants under the Option Agreement, dated December 30, 2016 among Holdings, the Partnership, and Weston and, as a result of Holdings’ entry into a Restructuring Support Agreement with Armstrong Energy, Inc. (“Armstrong”), its creditors and certain other parties, which agreement was entered into in advance of Armstrong’s filing for bankruptcy relief under Chapter 11 of the United States Code in November 2017. The complaint further alleges that (i) Mr. Phillips violated fiduciary and contractual duties owed to Royal, Rhino GP and the Partnership and solicited, accepted and agreed to accept certain benefits from Holdings, Weston, the Yorktown entities and Messrs. Lawrence and Lawrence without the knowledge or the consent of Royal, Rhino GP or the Partnership and during a period in which Mr. Phillips was the President of Royal and a director on the board of Rhino GP and (ii) Holdings, Weston, the Yorktown entities and Messrs. Lawrence and Lawrence aided and abetted Mr. Phillips’ breaches of his fiduciary duties, tortuously interfered with the observance of Mr. Phillips’ duties under the Partnership’s and Rhino GP’s respective organizational agreements and conferred, offered to confer and agreed to confer benefits on Mr. Phillips without the knowledge or the consent of Royal, Rhino GP or the Partnership.

The complaint seeks (i) the rescission of the Option Agreement, (ii) the return of all consideration thereunder, including 5,000,000 common units representing limited partner interests in the Partnership, (iii) the cancellation of the Series A Preferred Purchase Agreement, dated December 30, 2016, among Royal, Rhino GP, the Partnership (the “Series A Preferred Purchase Agreement”) and Weston, (iv) the invalidation of the Series A preferred units representing limited partner interests in the Partnership issued to Weston pursuant to the Series A Preferred Purchase Agreement and (v) unspecified monetary damages arising from Mr. Phillips’ breaches of fiduciary duties and the other defendants’ aiding and abetting of such breaches.
