Malaysian Risk Service Contract

21Corporate Presentation December 2012

Background

Coastal entered into a Risk Service Contract with PETRONAS for the development of the Kapal, Banang and Meranti fields (KBM) offshore Peninsular Malaysia

Coastal will be a 70% partner and a local Malaysian contractor (to be named later) will be a 30% partner

The contract requires the drilling of 17 wells: 10 wells at Kapal, 4 wells at Banang and 3 wells at Meranti

Once the wells are drilled, Coastal will operate the production facilities and coordinate oil liftings, operating cost disbursements, etc.

There are existing discoveries at each field. Coastal estimates recoverable oil could be anywhere from 15 to 35 Mmbbl

Additional upside from exploration prospects

Page 22: Corporate Presentation December 2012.ppt€¦ · *Per RPS Energy, Ltd. Reserve evaluation as of March 31, 2012 ... 2,300 onshore T hailand, 3,700 boepd Mala ysia (3Q commencement)

22Corporate Presentation December 2012

Overview of Terms

The contract duration is 8 years ; the KBM SFRSC model strikes a balance in sharing of risks with fair returns for development and production of already discovered fields

PETRONAS remains the project owner while Contractors (Coastal and partners) are the service provider

Contractor will incur upfront costs for Petroleum Development and Operations and will be reimbursed upon first commercial production; the contractor will also be entitled to a Remuneration Fee per barrel from a pre-determined percentage of the field revenue

The reimbursement and remuneration are tied to cost and production performances; priority of payment shall be cost reimbursement of CAPEC and OPEX, followed by Remuneration Fee

Contractors are subjected to the Corporate Income Tax Act (CITA) and not the Petroleum Income Tax Act (PITA). Corporate tax payable by the Contractor Group under CITA is at the prevailing rate of 25%

Anticipated Costs / Timeline

First oil from Kapal field is expected beginning of 3Q13

The Capital Expenditure (CAPEX) of KBM Cluster is estimated to be USD320 million over 3 years

Coastal expects to fast track development of the fields using MOPUs and FSOs similar to how it has fast tracked development of its Gulf of Thailand assets

Further Exploration Potential

Richest source facies in the Songkhla basin are found within the lower Oligocene balanced-fill lake phase, an extensive carbonate‐rich interval with analogies to the Qingshankou and Nenjiang source strata in the Songliao Basin of China

Reservoirs associated with this lake type include lake marginal carbonate strata, lake marginal beach deposits, and deltaic facies that would tend to be restricted to the lake margin

Source rock is currently sitting in oil window; start of oil window is estimated to be between 6,250 - 10,000 feet

Thickness of source rock ranges from 77 feet to 300 feet in the center of the basin
