TULSA, Okla.--(BUSINESS WIRE)--Nov. 15, 2007--Syntroleum Corporation (NASDAQ: SYNM) today reported that Louisiana Governor Kathleen Babineaux Blanco and Dynamic Fuels, LLC have announced Geismar, Louisiana, as the site for Dynamic Fuels' new plant to produce renewable diesel and jet fuel. The $135 million facility will have a capacity of 5,000 barrels per day and is scheduled for completion in 2010.

Dynamic Fuels, LLC is a 50/50 venture between Syntroleum Corporation and Tyson Foods, Inc. (NYSE: TYS) to construct and operate multiple renewable synthetic fuel facilities. Dynamic Fuels selected Lion Copolymer's Geismar plant as the site for their first facility. The Geismar plant will have a capacity of 75 million gallons per year and will utilize Syntroleum's Biofining(TM) technology and feedstock supplied by Tyson Foods, Inc.

"The site provides excellent people, infrastructure and utilities with an outstanding safety and environmental record," said Jeff Bigger, senior vice president of Syntroleum Corporation. "We look forward to working with Lion and expect that installing our plant within the existing complex will minimize cost while keeping Dynamic Fuels on schedule for production in 2010."

In a press release issued yesterday by the State of Louisiana Economic Development office, Governor Blanco said, "I want to thank Dynamic Fuels for choosing Louisiana to create high-paying technical jobs and making the capital investment necessary to employ this new proprietary technology. This decision will allow even more Louisiana agricultural by-products to be converted into premium value-added products."

"The state of Louisiana, including Governor Blanco, the economic development team and local officials, have been outstanding partners to work with throughout our site selection process," said Jeff Webster, senior vice president of Tyson Renewable Products Division. "This marks another important milestone in the execution of our strategy of leveraging access to animal by-products, our trading skills and industry relationships to become a premier player in renewable energy."
