Cairn India Rajasthan – Block Overview  Major discoveries in Rajasthan  ~130 wells drilled, 20 discovers to date  Significant discoveries are Mangala, Aishwariya and Bhagyam  New oil province established – resource base around1 billion barrels  Over US$600m (net risked capital) investment to date  Target Block Production ~150,000bopd Total original block area = 11,108 km 2

Cairn India Northern Field Developments  Field Development Plans  We are aiming for Saraswati and Raageshwari oil fields to be on stream in 2007 subject to GOI approval and finalisation of an oil sales agreement. As of today some wells are available for export of oil  Mangala oil field, including Raageshwari gas field and the Thumbli water aquifer, is the first major field to be developed  Next in line will be Bhagyam / Shakti and Aishwariya oil fields, 6 and 12 months behind Mangala respectively. Detailed design and engineering is being run in parallel  A single MPT (Main Process Terminal) will be constructed to accommodate these fields

Cairn India Northern Field Developments  Field Development Plans (cont)  Other smaller fields will be looked at on a case by case basis as the infrastructure surrounding the larger discoveries are completed e.g. Raageshwari Oil  Cairn continue to appraise further areas of the existing Rajasthan blocks

Cairn India Mangala Field Development  Contract Strategy  Detailed Design Work  Man hour reimbursable at rates  Existing contract for Mangala with Mustang Engineering Houston. Work subcontracted to L&T Valdel in Bangalore and JPK Triune in Delhi  Procurement  Lump sums supply – currently by Cairn, option for main contractors to procure for and on behalf of Cairn  Main Contracts  Based on cost reimbursable rates measurable using RHICOMS  (Rider Hunt International Common Norms)  Bill of quantities with agreed measure on a monthly basis  Commissioning and Start-up will be by Cairn with contractor support at reimbursable man hour rates

Cairn India Mangala Field Development  Local Content Strategy  We are committed to maximising local content levels. Main contractors will be required to meet the minimum local content requirements.  We intend to nominate subcontractors where we feel confident that a local contractor would have the required experience and quality standards required

Cairn India Mangala Field Development  Execution Strategy  Site living and sleeping accommodation will be provided by Cairn through a separate sub-contract. We would expect any site offices to be provided by the individual contractors. Cairn will provide and give access to any land required for offices and storage of materials.  We would expect personnel to be rotated out of site  Procurement of key long lead equipment is being carried out by Cairn from their India HQ at Gurgaon.  Manufacturing and materials will be based on preferred Indian content

Cairn India Mangala Field Development  Execution Strategy (cont)  Main Contracts, preferred Indian JV or partner contractors with experience and capability, execution to mechanical completion, bulk procurement  Contact split as follows  Main Civil Contractor  Main Mechanical  Main Instrument and Electrical  Pipeline (s)  Camp Provider  Freight forwarding  ICS (integrated Control System)

Cairn India Mangala Field Development  Execution Strategy (cont)  Main Civil Work Scope  All civil engineering work with in the development area. To include roads, all building, tank, plant and process equipment and pipe work foundations, excavations, underground concrete tanks and separation pits and the like.  Main Mechanical Work Scope  All mechanical equipment installation, hook-up and mechanical commissioning to hand over. To include all site erected tanks and associated pipe work.

Cairn India Northern Field Developments  Payment  Cairn Finances are in place as widely reported.  Work will be carried out on RHICOMS. Work will be measure monthly and appropriate valuation submitted for payment.  Mobilisations and de-mobilisations to site are Lump Sum  Cairn are implementing a SAP financial system such that all payments will be expedited effectively

Cairn India Northern Field Developments  Project Objectives  Schedule – to meet 2009 production target  Quality - to meet international standards and achieve greater than 98% reliability of the process plant in continuous operation  Safety – zero fatalities and a TCRF of less than 0.7  Environmental – to have zero releases and minimal long term environmental impact  Cost - to meet approved budgets

Cairn India Northern Field Developments  Core Issues  Remote location little or no infrastructure  Low indigenous skill base in Rajasthan but who have high expectations  Water supply currently aim to develop water aquifers at Thumbli but this will be in parallel with construction work  Safety is always a challenge but zero fatalities is a must

Cairn India Northern Field Developments  Expectations  We expect to have RFQ’s for Mangala developments issued by the end third quarter of Long lead items by end first quarter 2007  We expect to place all main contracts by end of 2 Q 07  Expected start dates on site as follows :  Civil End 2Q 2007  Mechanical End 3Q2007  E&I End 3Q 2007  Pipeline (infield) End 4Q 2007
