Total and Samsung to expand the capacity of the Daesan plant in South Korea.

Paris, October 26, 2005 — Total and Samsung have decided to expand their common petrochemicals plant in Daesan (50%/50%) located on the west coast of South Korea. The global investment close to 600 million dollars will both expand and modernise the facilities improving the overall energy efficiency.

The steam cracker will be revamped to achieve a capacity of 850,000 tons per year of ethylene versus a current capacity of about 650,000 tons per year. An olefins conversion unit will be added to increase the production of propylene. The project also includes a new polypropylene line more than doubling the current capacity of 250,000 tons and a debottlenecking of the styrene monomer unit.

In the first phase of the project, the steam cracker and the styrene monomer will be revamped by mid-2007. In the second phase of the project, the new polypropylene and olefins conversion units will start-up approximately six months later.

The project will reinforce Total Petrochemicals commercial position within the fast growing Asian markets. Much of the new styrene monomer and polypropylene production from the Daesan plant will supply the Chinese packaging, automotive and consumer products markets.

This investment supports Total’s strategy to further develop in Asia with a target to double its polymer equity production by 2010.
