Jacobs Wins INEOS Fluor Contract to Build Next Generation Refrigerant Plant.

PASADENA, Calif. -- Jacobs Engineering Group Inc. (NYSE:JEC) announced today that it has been selected by INEOS Fluor to provide project management, construction management, engineering, and procurement services for the expansion of KLEA 125 (HFC 125 refrigerant) production at INEOS Fluor's Runcorn facility in England. INEOS Fluor is planning to increase production capacity to around 14,000 tons in response to demand for alternatives to hydrochlorofluorocarbon (HCFC) refrigerants.

Officials did not disclose the contract value, but noted that the first phase of the expansion plan is due for completion in 2005.

KLEA 125 has been manufactured on a smaller multi-product facility at INEOS Fluor's Runcorn facility. Its use is vital as a component in many non-flammable, energy efficient refrigerants, designed to replace CFCs and HCFCs that are being phased out under the Montreal Protocol on Substances that Deplete the Ozone Layer. Following this investment the unit will be dedicated to HFC 125 production.

"The demand for this refrigerant underscores the importance of HFCs as end users continue to replace HCFCs such as R-22, driven by requirements under the Montreal Protocol," comments Dirk Gekiere, operations vice president, INEOS Fluor. "Our investment in KLEA 125 will enable us to meet increasing customer demand for high quality refrigerants. To meet these needs it is vital that we have a contractor with a proven track record that we can trust to complete the project on time and to budget. Jacobs understands our demand for high standards and shares our passion for excellence. In them we are confident that we have the right partner for the job."

In making the announcement, Jacobs Group Vice President John McLachlan stated, "We are delighted at this opportunity to support our client with this strategically important project."

Note to editors:

--Jacobs, with over 35,000 employees and revenues approaching $5.0 billion, provides technical, professional, and construction services globally.

--INEOS Fluor is a world leading specialities business built on expertise and innovation in fluorine chemistry. The company is focused on the supply of fluorine-based products, technology, and services across a number of major industries from pharmaceuticals to automotive, speciality polymers to refrigeration and air-conditioning. It has manufacturing facilities at Runcorn in the UK; Mihara, Japan; and St Gabriel in the United States. The company employs around 400 people world-wide.

--HFC 125 is typically used in blended refrigerants such as: R-407C (HFC134a, HFC 125, & HFC 32) and R-410A (HFC 125 & HFC 32). R-410A is used in an increasing number of new air-conditioning systems to replace HCFC 22. It is more efficient than both R-22 and hydrocarbons and is considered to be the best environmental solution in these applications.

--Hydrofluorocarbon (HFC) refrigerants have enabled companies around the world to replace chlorofluorocarbons (CFCs) & hydrochlorofluorocarbons (HCFCs). These products are the most rigorously tested chemicals ever; they are non-flammable, recyclable, easy to handle and highly energy efficient, which is why industry regards them as the products of choice in a range of applications.

--HFCs are widely used in refrigeration and air-conditioning applications and underpin the most cost effective, energy efficient technology for commercial refrigeration systems. Their use spans automotive and office air-conditioning, domestic and supermarket refrigeration, and transport and chiller systems.
