With the purchase of Aristech Chemical Corporation's 1.5 billion pounds of polypropylene capacity, Sunoco placed itself among the top five producers of polypropylene. The acquisition added two strategically located production facilities. The first located in Neal, West Virginia, uses state-of-the-art manufacturing technology and is centrally located within the largest polypropylene consuming markets. The second plant located in LaPorte, Texas started its newest line in September 1999 and is capable of producing a wide range of specialized value-added products. These production facilities coupled with customer-focused operating personnel, deliver consistent, quality products that meet or exceed our customers' expectations.

Our newly acquired polypropylene product line is comprehensive and is used in everything from baby diapers to automobile bumpers. The newest line at LaPorte provides the ability to further differentiate our product line making specialized products for future markets. A customer-focused Technical Service and Product Development group supports the product line. Whether its assisting in fine tuning a customer's process to maximize

production or developing a new product that meets a customer's specific needs, the technical group works closely with our customers to deliver a quick response.

The polypropylene business acquired from Aristech delivers a broad product line, excellent technical support, quick response, and a willingness to make new products for demanding applications. To this Sunoco adds financial discipline and a streamlined organizational structure which gives this polypropylene business the strength to endure the downturns in the market and to continue to deliver value to our customers.
