DALLAS, April 22, 2013 (GLOBE NEWSWIRE) — Cubic Energy, Inc. (NYSE MKT:QBC) (“Cubic” or the “Company”) announces today that it has entered into a definitive agreement to acquire proven reserves, oil & natural gas production and undeveloped leasehold interest in Leon and Robertson Counties, Texas from Gastar Exploration Texas, LP (“GETLP”). The acquisition price to be paid by Cubic is $46,000,000 and includes drilling rights on approximately 16,300 net acres and production of approximately 2,050 boepd (97% gas: 3% oil) using a 6:1 conversion rate. The transaction is expected to close on or before June 5, 2013, subject to customary due diligence and closing adjustments, and with a property purchase price effective January 1, 2013 for purposes of allocating revenues and expenses and capital costs between GETLP and Cubic.

Calvin A. Wallen III, Cubic’s Chairman, CEO & President stated, “We are excited to take the first step in transitioning Cubic to a diversified oil & natural gas company. As Cubic moves forward with additional acquisitions, the East Texas EagleBine Assets will prove to be a critical first step with its upside in the oil rich Cretaceous Zone, including the Eagleford & Woodbine intervals. The asset also gives us great flexibility with the deeper Bossier, a prolific and highly commercial play that we have the option to develop as natural gas pricing improves.”
