By: /s/ Kazuya Imai ---------------------------------------- Name: Kazuya Imai Title: Senior Executive Managing Officer Chief Financial Officer June 10, 2005 Mitsui & Co., Ltd For Immediate Release To whom it may concern FINAL INVESTMENT DECISION ON LNG EXPANSION ANNOUNCED FOR NORTH WEST SHELF ------------------------------------------------------------------------- PROJECT IN WESTERN AUSTRALIA ---------------------------- Japan Australia LNG (MIMI) Pty., Ltd ("MIMI"), which is an ultimately owned equally by Mitsubishi Corporation and Mitsui & Co., Ltd., made a final investment decision on 10 June 2005 to expand the North West Shelf Venture's onshore liquefied natural gas plant in Western Australia, together with all of the venture's participants. The participants in the North West Shelf Venture are: Woodside Energy Ltd. (operator); BHP Billiton (North West Shelf) Pty Ltd ; BP Developments Australia Pty Ltd; ChevronTexaco Australia Pty Ltd ; Japan Australia LNG (MIMI) Pty Ltd; and Shell Development (Australia) Proprietary Limited. The NWS Venture's current LNG capacity is 11.7 million tonnes a year from its four-train integrated facility in conjunction with a fourth train, the construction of which was completed in last August. The expansion project will install an additional fifth train to process 4.2 million tonnes of liquefied natural gas a year in order to strengthen production capacity. Start-up of the operation is expected to be around mid-2008 for supply to the Asian market, where continuous active demand is expected. The production capacity will increase 40% to 15.9 million tonnes a year, and total expenditures for the fifth train and associated facility amount to 160 billion yen (MIMI's share; around 27 billion yen). LNG is regarded as an energy resource with low environmental impact compared with coal and crude oil, and demand for it is expected to grow further. The increment in supply from a politically stable country such as Australia should contribute to the reliable procurement of energy resources for Japan. Annual LNG demand in the Asian region including Japan was 90 million tonnes in 2004 and is forecasted to increase by 30% by 2010.

History; The North West Shelf Project ("NWS") is a natural gas development located around 130 km off the northwest coast of Western Australia that is based on huge gas and condensate fields discovered in the early 1970s. The project is Australia's largest resource investment, producing and supplying not only LNG but also crude oil, condensate, LPG, etc. The investment participants each hold a 1/6th (16.67%) share of the project. The sales of condensate commenced in 1984, and the supply of LNG to Japanese customers, such electric power and gas companies, began in 1989. In addition, the Wanaea oil field and Cossack oil field were discovered in 1989, and crude oil and LPG production from these fields went on stream in 1995. 2. Production results and forecast; The annual production results of LNG, crude oil, condensate, LPG (not including gas for domestic consumption) in 2004 totaled around 440,000 barrels oil equivalent per day. The expansion project to install a fifth train is expected to increase LNG, condensate and LPG production to around 580,000 barrels oil equivalent per day in 2009, when the operation of the fifth LNG processing train will start.
