LS9'S ULTRACLEAN DIESEL(TM) RECEIVES EPA REGISTRATION

SOUTH SAN FRANCISCO, CA - April 13, 2010 - LS9, the Renewable Petroleum Company(TM), today announced that its UltraClean Diesel(TM), a diesel replacement product offering an 85% reduction in carbon footprint, was officially registered by the United States Environment Protection Agency (EPA). As a registered fuel, LS9's UltraClean Diesel(TM) can be sold commercially in the United States.

"This registration clears the way for LS9 to help reduce greenhouse gas emissions by bringing to market a low-carbon, advanced biofuel that can be used in today's engines," said Bill Haywood, LS9's Chief Executive Officer. "This is yet another significant achievement for LS9 and a huge breakthrough for advanced biofuels."

The chemical composition for LS9's UltraClean Diesel(TM) is compatible with the existing infrastructure and has a more desirable environmental footprint than conventional diesel. Production of LS9 UltraClean Diesel(TM) provides an 85% reduction in greenhouse gas emissions when compared to conventional petroleum diesel. In addition, LS9 UltraClean Diesel(TM) is free of benzene, a common carcinogen, and contains only trace amounts or sulfur, both of which are generally associated with conventional diesel products.

LS9 is the low-cost producer of advanced biofuels products. LS9's UltraClean Diesel(TM) is the only finished diesel replacement directly produced by fermentation of renewable raw materials in a single step. The company's proprietary one-step process has higher yields and removes additional production costs associated with the multi-step processes required by other advanced biofuel technologies. LS9's technology also results in superior products that are designed to optimize overall performance. LS9 genetically engineers microorganisms to precisely produce fuels with improved properties such as cetane, volatility, oxidative stability and cold-flow.

In addition to low-carbon transportation fuels, LS9's proprietary one-step fermentation process is capable of producing high-value chemicals used in making industrial and consumer products.
