The English Commercial Court in London has set the date and time for its decision in relation to the claims asserted by Excalibur Ventures LLC (Excalibur) against Gulf Keystone Petroleum Limited and its two subsidiaries (the "Companies") and Texas Keystone Inc. (together the "Defendants") as 10.30 a.m. on 10 September 2013 (the "Decision").

The Judge has indicated that he will read in open court his Decision and a summary of his conclusions will be available at www.judiciary.gov.uk on the day. The full, written judgment will not be made public until a later date.

As the Decision will be given in real time in open court and in order to maintain an orderly market in the Company's shares, Gulf Keystone confirms that trading in its shares on AIM will be suspended (the "Suspension") from 7.30 a.m. on 10 September 2013 and this Suspension will remain in place until such time as the Company releases an RNS giving details of the Decision, which is expected to be later the same day.
