On August 20, 2018, Energy XXI Gulf Coast, Inc., a Delaware corporation (“EGC”), learned that Orinoco Natural Resources, LLC, a Virginia limited liability company (“ONR”), has filed a complaint against EGC in the Superior Court of the State of Delaware (the “ONR Complaint”).

As announced by EGC on May 10, 2018, EGC entered into a non-binding term sheet with ONR and certain of its affiliates with respect to a proposed transaction primarily intended to transfer a portion of EGC’s non-core oil and gas assets and related liabilities, including asset retirement obligations, to an affiliate of ONR (the “Potential ONR Transaction”). The non-binding term sheet did not contain an exclusivity provision and was terminable by either party upon the payment of the other party’s documented out-of-pocket expenses, up to $1 million. EGC terminated the non-binding term sheet shortly prior to entering into the Agreement and Plan of Merger with affiliates of Cox Oil LLC (collectively, “Cox”) that was announced on June 18, 2018 (the “Merger Agreement”).

The ONR Complaint alleges, among other things, that EGC breached the non-binding term sheet for the Potential ONR Transaction, as well as the related nondisclosure agreement between EGC and ONR. The case is captioned Orinoco Natural Resources, LLC v. Energy XXI Gulf Coast, Inc. and Intrepid Financial Partners LLC, Case No. N18C-08-141.

The ONR Complaint does not seek to enjoin the transactions contemplated by the Merger Agreement. Instead, the ONR Complaint seeks damages from the defendants in the lawsuit and purports to seek restitution or disgorgement of EGC’s profits from the transactions contemplated by the Merger Agreement.

EGC believes that the ONR Complaint is without merit and intends to defend this lawsuit vigorously.
