Largest Cleantech Quarter Ever, Cleantech Grows to the Sixth Largest Venture Capital Investment Sector

ANN ARBOR, MI, December 8, 2005 - According to the Q3 2005 Cleantech Venture MonitorTM, cleantech investment totaled more than $425 million in 69 separate Q3 deals. This is the largest quarter ever recorded for the cleantech category, representing a 15.3% increase from Q2 2005. In the 3rd quarter of 2005 Cleantech captured 8.1% of the $5.263 billion of venture capital invested in North America overall, up significantly from 6.1% in the previous quarter. Cleantech now ranks 6th in size behind Software, Biotechnology, Telecommunications, Medical Devices and Equipment and Semiconductors. The Monitor is compiled by the Cleantech Venture Network LLC, a for-profit membership organization bringing insight, opportunities and relationships to investors, entrepreneurs and service providers interested in clean technology.

"The cleantech sector continues to garner increased attention from major companies, including the recent announcement by British Petroleum to commit more than $8 billion over the next ten years into alternative and renewable energy, we will continue to see the tremendous growth reflected in the Q3 2005 numbers," said Nicholas Parker, chairman and co-founder of the Cleantech Venture Network LLC. "As we look forward to the year ahead we believe that we will see the number and range of capital committed to cleantech deals continue to grow at an exceptional, but measured tempo."

"In late October Cleantech Venture Forum VIII in Washington DC attracted more than 300 attendees and featured cleantech comments and observations from Senator Hillary Rodham Clinton, Under Secretary of Energy David Garman and William McDonough among many other insightful presentations," said Keith Raab, CEO and co-founder. "We are thrilled to bring the Cleantech Venture ForumTM back to San Francisco in 2006. The event will again be held at the San Francisco Marriot from March 21-23, as we look to continue the organization's successful cleantech deal flow services and research efforts into the New Year."

The most active investor in Q3 was EnerTech Capital with five investments in the quarter. Chrysalix Energy, Draper Fisher Jurvetson and Kleiner, Perkins, Caufield & Byers participated in a total of three financings each.
