Oil and Gas East Africa Large Frontier plays Sizeable blocks Deep to ultra deep water Several recent discoveries Material resource potential Multiple play types Multi-TCF gas potential Stable/ progressive governments Favourably located for LNG markets India and Asian Pacific Kenya – Tullow: onshore oil discovery Tanzania – BG: 6, Statoil: 2 deepwater gas discoveries BG Mozambique – Anadarko & Eni discoveries An exciting exploration “hot-spot”

Tanzania – Deepwater activity Incumbents Smaller Africa focussed independents Majors renewed interest Some companies still targeting oil Two producing gas fields with sufficient reserves for domestic demand 4th offshore deepwater licensing round planned in 4Q 2012 Block 12 Block 11 Block 10 Block 9 Block 8 Block 7 Block 6 Block 5 Block 4 Block 3 Two producing fields: Songo Songo & Mnazi Bay Block 2 Block 2 E.

Success in first deepwater wells Farm-in June 2010, 60% of Blocks 1, 3 & 4 BG Operatorship – 1st July 2011 Six successful wells Gas discoveries Still in exploration phase Appraisal program in Q3 / Q4 2012 Also acquired substantial siesmic;5140 sq km 3D followed by 2,500 sq km 3D seismic in Block 1; evaluation ongoing In-country presence in Dar es Salaam and Mtwara – high quality national staff LNG Implementation Agreement and PSA gas terms already in place Tanzania – Significant Progress in Just 12 Months TANZANIA MOZAMBIQUE BG will spend $374m Gross or $199m over the $175m MWO amount. Moving away from 60/40 funding on that $199m means will spend $50m more net ($318m vs. $268m) or 25% of $199m.

Sharing the Operations Supply Base in Mtwara BG Operates the Mtwara Supply base on behalf of other offshore Operators (Petrobras, Statoil, Ophir) Upgrade commenced in 4Q 2011 to enable multiple drilling operations with improvements to benefit existing port users (cashew nut farmers) Tanzanian Ports Authority plans to develop free trade port and export corridor

Agenda 1 BG Group & Global LNG 2 Offshore East Africa – upstream overview 3 Tanzania – success so far Challenges 4

Capacity building initiatives BG scholarship scheme with the British Council and Nelson Mandela African Institute for Science and Technology Support for G&G studies at the University of Dar Es Salaam and University of Dodoma Pilot project for long term industry vocational training with VSO and VETA Mtwara road safety programme in partnership with National Institute of Transport School support program in Mtwara Marine Conservation and livelihoods project in partnership with Mnazi-Bay Ruvuma Estuary Marine Park Several social investment initiatives have been launched both in Mtwara as well as Dar es Salaam.

Operational challenges – remote location Lack of infrastructure and local service industries Deep water drilling Environmentally sensitive Capacity and skills development Piracy Joint initiatives for: Sharing port facilities in Mtwara Mutual Assistance between IOCs/ use of best technology Incident response (e.g. oil spill) Cooperation with Tanzanian navy

Business Environment Challenges Capacity and capability within Government and Parastatals Stability of contractual environment Levels of education and training within general population Direct experience of Oil and Gas Robustness of business systems and processes HSSE

LNG will require huge investment Upstream Liquefaction Shipping Regasification Markets c. 35-45% of investment c. 35-40% of investment c. 20-25% of investment c. 8% of investment $50 - 100 million per exploration well (deepwater) $8 - 20 billion upstream development cost 2 - 6 sq. mile site 3,500 construction personnel $5 - 16 billion downstream development cost $300+ million cost per vessel $5 million voyage cost (fuel, port, charter, boil-off) to India c.120 cargo loadings per year 1 LNG tank can store two Boeing 777’s $600+ million investment $90 - 350 billion gross sales revenue over project life Figures are highly variable depending on project scope and scale

LNG versus oil – illustrative cash flow Based on a generic greenfield LNG project LNG Expansion Oil Billion ($) Time from discovery of reserves LNG LNG development = longer lead times but significant long term benefits

LNG could deliver unprecedented benefits Historic Foreign Direct Investment (FDI) Positive impact on FDI, export earnings and government revenues Enabling legislation needed to maximise benefits Key challenges: Long lead time Political / institutional capacity Petroleum sector reforms Domestic energy expectations Macroeconomic impacts Exchange rate appreciation; “Resource Curse” An LNG project in Tanzania would be transformational for the economy and the country Proposed sector legislation / policies such as Gas policy, Gas Master Plan and Gas Act needs to be enabling and must encourage investments.
