Sabine Oil & Gas Announces Amendment to
its Forbearance Agreement to its Second Lien Term Loan Facility

HOUSTON — July 9, 2015 /PRNewswire/ — Sabine Oil & Gas Corporation (OTCQB:SOGC) (the “Company”)  today announced that on July 8, 2015, it signed an amendment to its previously announced forbearance agreement with the lenders under its second lien term loan facility.  The amended forbearance agreement will provide the Company with additional flexibility as it continues discussions with its creditors and their respective professionals regarding the Company’s debt and capital structure.  Pursuant to the amendment to the forbearance agreement, the lenders under the second lien term loan facility have agreed to forbear from exercising remedies until the earlier of (i) certain events of default under the forbearance agreement or second lien term loan facility, (ii) the acceleration or exercise of remedies by any other lender or creditor, and (iii) the earlier of the termination of the forbearance period under the Company’s revolving credit facility and July 15, 2015 (the “Forbearance Period”), with respect to the Company’s currently existing events of default under the second lien term loan facility.  In exchange for agreeing to forbear, the Company has agreed during the Forbearance Period to, among other things, tighten certain covenants under the second lien term loan facility.

As previously announced, the Company has retained financial advisors, Lazard, and legal advisors, Kirkland & Ellis LLP, to advise management and the board of directors on strategic alternatives related to its capital structure.  The Company believes it is in the best interests of its stakeholders to actively address the Company’s debt and capital structure and is continuing discussions with its creditors and their respective professionals. As previously reported, as of May 8, 2015, the Company had a cash balance of approximately $276.9 million, which provides substantial liquidity to fund its current operations. The Company is continuing to pay suppliers and other trade creditors in the ordinary course.

Additional information about the amendment to the forbearance agreement is contained in a report on Form 8-K filed today with the SEC.
