Gulf Keystone Petroleum Ltd. (AIM: GKP)

("Gulf Keystone" or "the Company")

Update on Excalibur litigation and proposed move to the Main Market

On 10 September 2013 the English Commercial Court provided a summary of its decision to dismiss all of the claims asserted by Excalibur Ventures LLC ("Excalibur") against the Company, its two subsidiaries and Texas Keystone Inc. (together the "Defendants") and decided all issues in favour of the Defendants.

The Company today confirms that the English Commercial Court has set 10.30am on 13 December 2013 as the date for both the handing down of its full judgment (the "Judgment") and the hearing of consequential matters, including the costs of the litigation and any application that may be made by Excalibur for permission to appeal the Judgment.

The Company believes that clarity in the Excalibur litigation process is important for the move-up to the Main Market of the LSE. In view of the date for the handing down of the Judgment and Excalibur's right to apply for permission to appeal at the Hearing, (or to the Court of Appeal if the English Commercial Court refuse permission to appeal), the board of Gulf Keystone expects conclusion of the proposed admission to trading on the Main Market to be as soon as practicable in 2014.

Further announcements will be made as appropriate.
