Drilling Update

In Turkey, the Company expects its first Selmo oil field infill well, the S-54, to commence oil production in a few days. The Company will resume testing the Atesler-1 well shortly upon the arrival of a straddle packer. The packer will isolate certain water bearing zones to determine if a preliminary oil show will be economic to produce. In the Arpatepe field area, the Company is coordinating with its 50% partner, Aladdin Middle East, on the drilling of the Arpatepe-3 well, which is expected to be drilled in the fourth quarter. The Company is also coordinating plans with Aladdin to drill additional exploration and appraisal wells to test other prospect areas on the Arpatepe license.

In Morocco, the Company has drilled the HR-33bis well to a total depth of 3,521 feet and is awaiting logging and perforating tools to test and complete the well. The Company continues to experience drilling difficulties on the OZW-1 exploration well on the Ouezzane-Tissa license.

In Romania, the Company is currently drilling the fourth well of its seven-well 2009 drilling program. The Company plans to commence testing and completion of these four wells beginning in late October. The Company expects to commence drilling the first of three planned exploration wells on the Sud Craiova license in late October. The Sud Craiova wells will target shallow tertiary aged sandstones, which are expected to be natural gas bearing, at a depth of less than 1,000 meters.
