PTTEP’s initial investment in Australia since late 2007 Perth office Darwin Logistic Base Truscott Airfield Cash Currently, PTTEP or PTTEPAA has our portfolio of 19 permits including non-operating and operating. Besides Montara, we have Cash Maple gas fields to be developed. Completed Maple-2 drilling in July (flow rate: 30 MMSCFD of natural gas and 696 BBL/D of condensate), proving the potential after successful Cash-2 well in 2011. Completed 3D seismic acquisition in 2012. Processing 3D data and re-mapping field to confirm  reserves. Ongoing studies on upstream, alternative development, partnership, and project viability. As a NOC company, we are committed to bring LNG to Thailand (nation energy security). In short-term plan, we are focusing on delivery these two current operated projects - Montara and Cash Maple – and on other 10+ permits in our portfolio which are mostly exploration and appraisal program. We have to maximize value of our existing assets. JV partners are welcome. In long-term, we plan to seek additional M&A opportunities and acquire interest either op. or non-op. in near-production assets. Bidding for further exploration footprint expansion is one of the plan. Number of Permits Exploration Retention Production Total Operating 7 4 5 16 Non-Operating 3 10 19

Experience Sharing : Risk vs Rewards Geological complexity Huge resource base – both conventional & unconventional High cost of operations (e.g. FX, labor) Potential investment opportunity Logistics and Project management Political stability Stringent environmental and safety regulations Supportive Government + Macro: Australia is geographically very relevant for PTT as it is an extension of the southern corridor and close PNG, TE, Indonesia and New Zealand. In addition to servicing Pacific basin, its LNG cargoes are capable of serving Indian ocean, and can have a big role to play in Thailand’s energy security. Australia is likely to remain a net exporter of hydrocarbons in foreseeable future. Macro: Australia has a stable political regime and the government is pro-investments in oil and gas. It has very attractive fiscal terms with 40% PRRT, 30% corporate tax and full cost recovery. Government is actively promoting investments in exploration by allowing up to 50% additional upliftment of certain exploration costs in frontier areas - Upstream market is extremely competitive and G to G relations add little distinctiveness. Execution challenges given the labor shortage and tight environmental and safety regulations Australia has huge hydrocarbon potential and is relatively underexplored Conventional oil and gas resources are 31 bboe with a similar amount of Yet to Find resources CBM potential of Australia is suggested to be even bigger than conventional oil and gas Renewable energy Australia remains as PTTEP’s growth hub. PTTEP’s goal of being a valued long-term investor in the Australian O&G industry and transforming our safety and environmental practices to meet the Australian Government’s expectations

Key Takeaway ASEAN Market is huge with high potential buyer. Thailand is an attractive choice for Australian investors to do business and invest in manufacturing industry because of its strategic location and excellent infrastructure. As Thailand is net energy importer country, Australia can play key role in supplying LNG to match with Thailand’s needs. PTTEP, Thailand NOC investing in Australia, has successfully applied lessons learned and best practice to corporate and subsidiaries roll out. PTT Group welcomes Australian companies as partners in upstream and downstream. We are pleased to support Australian companies in doing business in our region.
