Completion of Balance Sheet Restructuring

Board Changes

Appointment of Corporate Broker

Gulf Keystone is pleased to announce that the Scheme of Arrangement (the "Scheme") in connection with the Balance Sheet Restructuring Transaction (the "Restructuring") announced on 14 July 2016 became effective today. The expected settlement date for the Scheme is 14 October 2016.

In addition, the Company also announces Board changes, which take effect from today. David Thomas and Garrett Soden are appointed as Non-Executive Directors and Cuth McDowell steps down as Non-Executive Director from the Board at the same time.

Finally, the Company announces the appointment of Canaccord Genuity as sole corporate broker.

Restructuring

The Restructuring involves the implementation of a new capital structure to materially strengthen the Company's balance sheet with a significant debt reduction from over US$600 million to US$100 million through the conversion of over US$500 million of existing debt into equity of the Company by way of the Scheme.

In addition, Gulf Keystone has increased its liquidity by raising $25 million through an over-subscribed Open Offer. This improved liquidity allows the Company to implement the near-term investment plan of maintaining production at 40,000 barrels of oil per day ("bopd"), and with the potential to increase production to 55,000 bopd, subject to the Kurdistan Regional Government's Ministry of Natural Resources ("MNR") and MOL's approval.

Admission of and commencement of dealing in 21,910,523,553 new common shares pursuant to the Open Offer and Debt Equitisation are expected to occur on 14 October 2016 (the "Admission date"). Qualifying Shareholders will be notified of their allocation of new common shares within 14 days of the Admission date. Due to the Open Offer being oversubscribed, certain applications made by Shareholders under the Excess Entitlements Facility were scaled back in accordance with the terms of the Open Offer. Excess funds in respect of applications that were not met in full will be returned to the applicant within 14 days of Admission.

Given the challenging set of circumstances that we faced, I am pleased with the outcome of what has been a long and complex process. With its restructured balance sheet, the Company is now in a far stronger position than it has been for several years and we can look forward to continuing to develop Shaikan and rebuilding value for all stakeholders."
