Southern California Financial Industry Veteran Joins Silicon Valley Bank

Expertise and Community Connection of Former Comerica Ventures SVPComplement Seasoned Venture Capital and Emerging Technology Team

Palo Alto, CA - September 23, 2002 - Silicon Valley Bank, a wholly owned subsidiary of Silicon Valley Bancshares (SVB), today announced that Tim Bubnack has joined its Southern California Venture Capital and Emerging Technology division. Bubnack previously served in senior executive positions at Comerica Ventures, Inc. and Comerica Capital Advisors and augments the Bank's already considerable connections and experience in Southern California with more than 13 years of technology investment and financial expertise.

"Tim is a seasoned veteran with a successful track record in providing debt and equity products to early stage and growth technology companies," said Terry Bess, Southern California region manager. "He is well-known and respected in the Southern California financial community and his decision to join us sends a strong signal that Silicon Valley Bank is the right place for startup and emerging tech investment."

As a Director at the Bank's San Diego offices, Tim will serve as the venture capital liaison for Southern California focusing primarily on local emerging technology clients. In this new role, he will focus on identifying new banking and investment opportunities, and take an active role in managing existing client relationships. This includes a key role in support of the Bank's venture capital clientele in Southern California.

"Our San Diego office has grown by 25 percent in the past year, as we've added staff to accommodate our increased share of the local market and support our continued market expansion," said Managing Director, John Otterson. "Tim knows from long experience what it takes for a start-up technology company to grow and ultimately succeed; his financial experience will be a tremendous addition to an already seasoned team."

Before joining SVB, Tim served as senior vice president of Comerica Ventures and Comerica Capital Advisors, where he was responsible for identifying and assessing venture investment opportunities. Before joining Comerica, he was Senior Vice President of Imperial Bank's Southern California Emerging Growth Division, which he co-founded in February of 1998. Prior to Imperial, Tim was a Vice President with First Interstate Bank's Corporate Banking Division in San Diego.

"I have a great passion for working with entrepreneurs and helping early-stage technology companies develop into industry leaders. Silicon Valley Bank is committed to serving the entrepreneur and the venture capital community and is better positioned than any bank locally or nationally to support the transition from early stage to industry leader," Bubnack said.

Tim holds a bachelor's degree in business economics from the University of San Diego and is very active in the local professional community. He is involved in UCSD CONNECT, the Software and Industry Council, the San Diego Venture Group, and the Southern California Tech Coast Angels. He is also a member of the Board of Directors of the San Diego Regional Technology Alliance, an advisory board member of San Diego State's Entrepreneurial Management Center, and an advisory committee member of University of San Diego's Donald P. Shiley Center for Science and Technology.
