Asset Sales Update
The Company has signed a definitive agreement to sell its interest in certain non-operated properties located in the Hugoton Basin in Kansas to an undisclosed buyer for a contract price of $31 million, subject to closing adjustments. The estimated net proceeds from the sale are expected to be added to cash on the Company’s balance sheet. Use of proceeds will be determined by Board and management, which may include share repurchases under the Company’s previously announced share repurchase program, share tenders, and/or reinvestment in higher return projects at Blue Mountain or in the upstream business.

The properties to be sold consist of approximately 2,300 non-operated wells located in Hugoton Basin with proved developed reserves of approximately 74 BCFE¹ and proved developed PV-10 of approximately $30 million¹. The production from these properties will continue to be processed at the Company’s Jayhawk natural gas processing plant located in southwest Kansas.

The sale is expected to close in the second quarter of 2019 with an effective date of March 1, 2019. This transaction is subject to satisfactory completion of title and environmental due diligence, as well as the satisfaction of customary closing conditions.

Blue Mountain Third-Party Dedication
Blue Mountain finalized an agreement with an undisclosed third party to dedicate a portion of its leasehold position in the Merge as an additional customer for natural gas gathering and processing services on Blue Mountain’s system. The dedicated acreage is located in Canadian, Grady, and McClain counties, Oklahoma. The agreement provides a long-term acreage dedication with the potential for incremental volumes as drilling activity advances within the dedicated acreage footprint.
