SAN BRUNO, CA ­ May 21, 2008 ­ VantagePoint Venture Partners, one of the nation's premier venture

existing team of exceptional leaders who contribute experience and expertise to a diverse and increasing

particular interest in distributed generation, electric transport and biofuels. Woolsey has been a senior
advisor to VantagePoint since 2006 and former Director of Central Intelligence (1993-95). "He brings a

landscape to assist entrepreneurial companies as they navigate the CleanTech terrain and reach global
scale," said Stephan Dolezalek, Managing Director and Head of the CleanTech Practice Group.

Edwards joins the Firm from Morgan Stanley where he covered the CleanTech industry as an equity
research analyst focused on the solar, wind, storage, efficiency, and biofuels markets. He is steeped in
the market dynamics of the CleanTech industry and possesses a valuable perspective that will benefit
portfolio companies as they move from development to commercialization and into the public markets.

Van den Berg joined the Firm in 2006 with more than 25 years technology and industry experience.
Having participated in building three successful companies in the energy, water and semiconductor
sectors, he contributes a rare depth of operating experience and technical knowledge to our portfolio
companies. Van den Berg is focused on solar, lighting, storage and smart grid technologies. He works
with key portfolio companies Bridgelux, Miasole and Angstrom Power.

VantagePoint has established a leading CleanTech Practice with the team, resources and relationships
necessary to meet the large and rapidly growing opportunity. "The scope of the issues being addressed --
energy security, climate change, clean water and resource scarcity -- represents an opportunity of
substantial magnitude, and we have assembled a team that knows how to build companies that will have
significant impact and transform their industries," said Alan Salzman, Managing Partner and CEO,
VantagePoint Venture Partners.
