Co-Founders of Diamondhead Ventures Join Forces with Onset Ventures

Shared Values, Synergies Bring Two Early Stage VC Firms Together

MENLO PARK, CA – October 1, 2007 – ONSET Ventures today announced that the two founding partners of Diamondhead Ventures, Raman Khanna and David Lane, will join ONSET Ventures as Managing Directors of ONSET V. The pair's long-time experience and successful track record in early-stage investments, particularly in the information technology (IT) sector, will be synergistic with ONSET's venture craftsmanship focus, and will uniquely enhance its IT investment team.

The two partners, whose Diamondhead Ventures fund has co-invested and worked with ONSET over the years, will continue their oversight of that fund while immediately participating in ongoing investments in ONSET's most recent $200 million fund, ONSET V.

"Because of the rich opportunities available, we have been eager to expand our investment team in the IT sector – one of our historical areas of focus," said Rob Kuhling, Managing Director of ONSET. "It is unusual to find individuals who have not only a wealth of experience in the sector, but closely share our values and philosophies about crafting successful businesses. After having worked with Raman and David over the years, the potential for great synergy became increasingly apparent to both teams, and today we've institutionalized it."

Of particular relevance, said ONSET Managing Director Terry Opdendyk, is that at Diamondhead Ventures, Khanna and Lane systematically nurtured a rich ecosystem of top-tier university, industry, corporate, and financial alliances that they credit highly for the superior returns to date of their fund. "Not only do we strongly believe in this strategy," said Opdendyk, "but in combination with our own network, it becomes a formidable platform for finding and developing new opportunities and entrepreneurs."

Khanna and Lane founded Diamondhead Ventures in 2000 with the formation of Diamondhead I, a $140 million fund. Since that time, the partners have made 21 investments in information technology. These investments have included Series A financings of Cavium Networks (NASDAQ: CAVM) and UPEK, which has recently filed an S-1 registration statement. The fund has, to date, generated returns to its investors that puts it at the high-end of the top quartile of all 2000-vintage funds.

"Our successful investment model is based on leveraging a unique set of university and industry relationships to identify and source emerging technology opportunities," said Raman Khanna. "With many of ONSET's recent IT investments coming out of universities, it is clear that ONSET holds a similar view of the power of such relationships. In addition, we share with our new partners a belief that medical technology is another fertile area for investing in the future, which is also one of ONSET's strong suits. We envision a powerful combination." Khanna and Lane's "ecosystem" includes leading researchers at Stanford University, University of California at Berkeley, Carnegie Mellon University, and the University of Southern California, among others.

David Lane further outlined the synergies with ONSET: "In working alongside ONSET during the last decade, we have found that the firm shares with us a 'roll up your sleeves' attitude combined with pragmatic, milestone driven management processes. There are many ways to practice venture capital, but ONSET's 'venture craftsmanship' approach is very similar to how we practice."

Moreover, Diamondhead's Venture Advisors will be involved with ONSET Ventures as well. Both Lane and Khanna will continue to manage the Diamondhead I fund and its investments.

"We are big believers in the early-stage venture capital model, but today there are fewer and fewer firms that are genuinely focused on it," said Jamey Sperans of Morgan Stanley, a long-time investor in ONSET Ventures. "I have known both firms for many years and am a big supporter of their distinctive hands-on approach. The addition of David and Raman to ONSET is very exciting."

About ONSET Ventures

ONSET Ventures specializes in providing an ideal mix of start-up, follow-on, and intellectual capital to entrepreneurs and early-stage technology ventures to help transform world-class ideas into sustainable and valuable businesses, through a process of "venture craftsmanship." The firm has backed over 100 companies since 1984 and now has more than $700 million under management.

ONSET's venture craftsmanship, refined over 20 years, includes a highly-optimized tool set for risk and capital management, and a shirt-sleeves style of active collaboration with entrepreneurs that leverages the firm's substantial operating experience. That collaboration frequently begins before the closing of any financing, and typically continues throughout the life of the venture. This approach, which has become the hallmark of the firm, has resulted in a crafting of ventures that have consistently met their operational and financing milestones. In addition, it has resulted in a franchise that not only brings successful, serial entrepreneurs back to ONSET Ventures time and again, but also attracts investors who want the increasingly rare opportunity to participate in very early stage venture investing.

ONSET Ventures focuses exclusively on information- and medical technology-based start-ups, and has a long history of successful ventures in each of these sectors.
