Over the past 18 months, Black Rock Oil & Gas PLC has transformed itself from a cash shell to an exploration company with significant potential by: –Adopting a low risk exploration strategy –Farming-in to acreage that meets these criteria –Creating a balanced portfolio in terms of geographical spread and near-term production –Building an experienced management team to implement this growth strategy Transformation

Summary Attractive acreage; low risk projects Active drilling programme planned in 2006; potential to prove up in excess of 30 million barrels of oil energy equivalent net reserves (Arce, Baul and Monterey) Management team strengthened with appointments to the Board North Sea acreage has potential to transform Black Rock into a significant UK independent over time

The Board Tony Baldry MP, Chairman Ivan Burgess, Chief Executive Officer Dr John Cubitt, Technical Director John Bottomley, Director

Strategy To focus on generating near term cash flow by: –acquiring previously non-commercial or undeveloped discoveries –targeting bypassed pay and acreage adjacent to existing producing fields To balance low risk production with high quality exploration projects –acquiring exploration acreage in known hydrocarbon provinces –avoiding high risk basins and countries –working with successful operators with established track record and local knowledge/expertise –seeking significant equity interests to maximise financial flexibility

2005 Highlights

2005 Tested and flowed oil at Arce 3 in Colombia

Activity Summary

PREDICTION Achieve commercial production in Colombia during 2006

AIM To be cash positive by end of 2007

Dr John Cubitt Technical Director

2006 In 2006, Black Rock is expecting to: –Generate cash flow from a Colombian steam flood –Test two further Colombian oil fields –Undertake an appraisal of a UK gas field –Prove up net reserves of 30 mmboe –Drill a significant UK exploration opportunity

Assets Planned activities summary: Colombia: Middle Magdalena Basin Potential near term cash flow 50% joint venture with Kappa Energy Steam flood testing in early 2006 Arce 4 and 5 to be drilled in Q Potentially producing 2H 2006 Testing Baul and Bukhara Seismic acquisition Exploration well drilling

Arce Oil Field Discovered 1984, shallow heavy oil 3 wells drilled, 30 feet net pay Arce 3 tested 30 bopd with constant water cut Steam testing in early 2006 Estimated gross reserves of 5-10 mmbo Five well pilot project should produce in excess of 115,000 barrels of oil Peak production from Arce could reach 3,200 bopd after 3 years Chicala Oil field is on production using steam flood techniques

Baul Oil Field Baul 3 produced 16,610 barrels of oil from a 14’ sand in Testing in Q2/ Estimated recoverable reserves of 2-3 mmbo of which 1mmbo is contained in the proven 14’ sand Discovered 1960, shallow heavy oil, 5 wells drilled, 100’ net pay

Bukhara Oil Field Discovered 2000, shallow heavy oil 1 well drilled, 175 feet net pay 2005 test inconclusive Re-testing in early 2006 Estimated recoverable reserves up to 75 mmbo

Colombia – Exploration Opportunities (1) Las Quinchas Association Contract Perspective block containing a number of opportunities, ranging from shallow heavy oil to light oil targets in the deep Cretaceous * Operator estimated mean reserves –Acacia (15mmbo*): heavy oil prospect –South Lalinda (10 mmbo*): heavy oil prospect –Rio Viejo/La Tolda (49 mmbo*): light oil, 18,000 ft target depth –Morroa – another deep Cretaceous play One deep Cretaceous test well planned for 2006

Colombia – Exploration Opportunities (2) Awarded in September 2005 as a result of farm-in agreement with Kappa Alhucema Association Contract Similar geology to Las Quinchas – heavy and light oil prospects –Possible extension of Chicala oilfield trend –Northern extension of Morroa lead

Core Assets Planned activities: UKCS farm-in: One well to be drilled in each of 22/14b and 49/8c Offshore UK Perspective acreage adjacent to existing oil and gas fields

Southern Gas Basin Significant Carboniferous gas find, discovered 1989 Monterey Gas Field Well flowed at up to 5 mmcf/day Petrophysics suggests a 300 feet gas column Drilling planned for Q Operator estimated mean recoverable reserves of 165 bcf Development via a 2 well subsea tieback, probably to Markham field Prospect Stinson, on 49/8c; operator estimated mean recoverable reserves of 147 bcf

Northern North Sea 3 targets in the Tertiary, Jurassic and Triassic, significant oil potential Huntingdon Prospect Drilling planned in Q1/Q Operator estimated mean recoverable reserves of 48 mmbo 9 other prospects in Blocks 22/14b and 22/19b
