About Verenium Corporation (VRNM):

Cambridge-based Verenium Corporation is a leader in the development and commercialization of cellulosic ethanol, an environmentally-friendly and renewable transportation fuel, as well as high-performance specialty enzymes for applications within the biofuels, industrial, and health and nutrition markets. The Company possesses integrated, end-to-end capabilities in pre- treatment, novel enzyme development, fermentation, engineering, and project development and is moving rapidly to commercialize its proprietary technology for the production of ethanol from a wide array of feedstocks, including sugarcane bagasse, dedicated energy crops, agricultural waste, and wood products. In addition to the vast potential for biofuels, a multitude of large-scale industrial opportunities exist for the Company for products derived from the production of low-cost, biomass-derived sugars.

Verenium's Specialty Enzyme business harnesses the power of enzymes to create a broad range of specialty products to meet high-value commercial needs. Verenium's world class R&D organization is renowned for its capabilities in the rapid screening, identification, and expression of enzymes-proteins that act as the catalysts of biochemical reactions.

Verenium recently completed a significant upgrade of one of the nation's first operational cellulosic ethanol pilot facilities located in Jennings, Louisiana and expects to achieve mechanical completion of a 1.4 million gallon-per-year, demonstration-scale facility to produce cellulosic ethanol by the end of 2007. In addition, the Company's process technology has been licensed by Tokyo-based Marubeni Corp. and Tsukishima Kikai Co., LTD and has been incorporated into BioEthanol Japan's 1.4 million liter-per-year cellulosic ethanol plant in Osaka, Japan -- the world's first commercial-scale plant to produce cellulosic ethanol from wood construction waste.
