PRESS RELEASE
April 26, 2005

INEOS Group Holdings plc (‘INEOS Group’ or ‘The Company’) announces today that it has acquired BASF’s US and Canadian polystyrene business. The acquisition will be made by the Company’s wholly owned subsidiary, INEOS Americas LLC.

The business comprises a 400 kt/a manufacturing facility at Joliet, Illinois producing general purpose polystyrene (GPPS) and high-impact polystyrene (HIPS). Polystyrene is a versatile thermoplastic resin that is used in many applications, such as packaging, toys, electronic goods, magnetic and optical media, construction and appliance components.

The business employs 140 people including the Joliet workforce and management plus sales and marketing support at various locations who will transfer to INEOS at completion. The business will be operated as a separate division of INEOS Group.

“This is a business which ideally meets our acquisition criteria with excellent people, assets and market positions and the heritage of a major chemical company. As the second largest polystyrene facility in North America this acquisition gives us an excellent platform to enter the global styrenics business” according to INEOS Group Chairman, Jim Ratcliffe.

Completion of the transaction awaits approval by the Federal Trade Commission in the United States.

The acquisition will be funded by an extension to our Interim Finance Facility, which we previously announced in February 2005. The Interim Finance Facility represents an interim position to enable the Company to proceed with its planned investments before a full refinancing takes place, likely to be later in the year.
