AMYRIS : Cosan and Amyris Forming Novvi S.A. for Global Production and Commercialization of Renewable Base Oils

Cosan S.A. Industria e Comércio (BM&FBovespa:CSAN3) and Amyris, Inc. (NASDAQ:AMRS) announced today that they have executed a Joint Venture Implementation Agreement as the final step toward the commencement of operations in Novvi S.A., the Brazilian company established for the worldwide development, production and commercialization of renewable base oils made from Biofene®, Amyris's renewable farnesene. The companies executed in December 2010 an agreement to set the preliminary terms and the general conditions to conduct a set of business, technical and commercial studies and tests with the goal to assess the feasibility of the formation and implementation of a Joint Venture. The parties have now completed feasibility studies and are establishing the operating joint venture entity.

Novvi plans to commercialize a line of synthetic, renewable base oils for the lubricants market. Novvi's base oils are designed to improve upon key environmental metrics including biodegradability, toxicity and renewability when compared with petroleum-sourced base oils, while delivering performance characteristics comparable to Group III and Group IV base oils. Novvi expects to source Biofene initially from Amyris production facilities, convert it through chemical processing into high-end renewable base oils and market and distribute these base oils worldwide. Longer term, Novvi may construct dedicated Biofene production facilities.

"The formation of Novvi provides another important channel for commercialization of Biofene, and we are pleased to have Cosan as our partner in this," said Paulo Diniz, chief executive officer of Amyris Brasil. "We expect Novvi to introduce its first products starting next year."

"We have completed the market studies and production capabilities assessment and are now ready to operate our joint venture with Amyris," said Nelson Gomes, head of Cosan Lubricants. "The combination of Amyris's Biofene infrastructure and technology platform with our feedstock capabilities and supply and distribution infrastructure creates the foundation for Novvi to become the leader in high-performance renewable synthetic base oils."
