ISE Corporation Signs Exclusive Biodiesel Co-Marketing Agreement for Marketing Biodiesel to Heavy Duty Vehicle Market

SAN DIEGO, CA--(Marketwire - March 12, 2008) - ISE Corporation (ISE), a leading supplier of hybrid drive systems for heavy duty vehicles, and a subsidiary of Renewable Energy Group, Inc. (REG), one of the nation's largest producers and marketers of high quality biodiesel, have entered into an exclusive biodiesel co-marketing agreement for marketing REG-produced biodiesel to ISE hybrid drive system customers. ISE will market and promote REG-produced biodiesel to certain approved customers in conjunction with ISE's hybrid drive system products. The use of biodiesel to fuel ISE's diesel-hybrid drive systems will enable customers to substantially lower their greenhouse gas emissions, in addition to the NOx and PM emissions reductions already enabled by ISE's diesel-hybrid drive systems.

Initial target market segments will include transit buses, refuse vehicles and port drayage vehicles in the United States. Under the agreement, ISE will introduce REG-produced biodiesel to certain ISE hybrid drive system customers. REG will contract directly with such customers to provide high quality biodiesel and injection equipment which allows biodiesel to be mixed with petroleum diesel at any blend level. ISE will assist REG in identifying customer depot locations, number of vehicles, existing fuel tank sizes, and potential locations for biodiesel utilization.

"We are excited about making biodiesel available to our customers and look forward to collaborating with REG in this important project," said David Mazaika, CEO of ISE Corporation. "With REG providing biodiesel direct to our customers, this will accelerate broader use of this reasonably priced, environmentally sensitive fuel, while substantially reducing greenhouse gas emissions from these heavy duty vehicles."

"Municipalities, government fuel purchases and fleet operators are increasingly demanding high quality biodiesel to help meet state and federal emissions requirements and meet their constituents' demands for ways to 'go green,'" explained Jon R. Scharingson, REG's Director of Marketing. "REG is excited to enter into this partnership with ISE as a way to offer large volumes of high quality biodiesel to be distributed to a market segment looking to adopt environmentally sustainable transportation options."

Biodiesel can easily be introduced into diesel-hybrid fleets. Biodiesel is mixed with petroleum diesel at any blend level; the most popular mix is currently B20 (20 percent biodiesel and 80 percent petroleum diesel). Pure biodiesel, or B100, marketed by REG is guaranteed to meet or exceed the industry quality specification.
