Lansdowne Oil & Gas plc (“Lansdowne” or “the Company”)

Licence Update

In June 2008 Lansdowne granted a Farm-In Option to Island Expro Limited, a subsidiary undertaking of Island Oil & Gas plc (“Island”) over the prospective Old Head Gas Trend in Licence 4/07. Island subsequently acquired c 130km of new 2D seismic data over Licence 4/07 at no cost to Lansdowne. This new data is considered by Lansdowne to be a significant improvement on the older data and has been incorporated into the re-mapping of the prospects identified in the southern part of Licence 4/07. Details of the results of this re-evaluation will be included in a full updated Competent Persons Report on all of Lansdowne’s acreage which is anticipated to be released in February 2009.

Under the terms of the Farm-in Option, Island had until December 31st 2008 to commit to drill a well to earn-in to Licence 4/07. No such undertaking was received from Island and this option has now lapsed, with Lansdowne retaining 100% equity in the Licence.
