PALO ALTO, Calif.--(BUSINESS WIRE)--

Hercules Technology Growth Capital, Inc. (NASDAQ:HTGC), the premier specialty finance company providing venture debt and equity to venture capital and private equity backed technology and life science companies at all stages of development, today announced that it has surpassed $1 billion in originations since its founding in 2003.

With the recent financing of Glam Media, Inc., in March 2008, Hercules now has surpassed $1 billion in total venture debt and equity commitments to more than 110 portfolio companies across the technology and life sciences industries. Within those industries, Hercules' funding has been focused on communications and networking, semiconductors, medical devices, biopharmaceuticals, wireless communications, social networking and other select Web 2.0 companies. The company has provided growth capital to companies at various stages of development, such as Ekos Corporation, Jab Wireless, Inc., and hi5 Networks, Inc.

    Moreover, notable investments in the past five months include:

    --  Providing $20 million in debt financing to Kamada Ltd., an
        Israeli biopharmaceutical company, in January 2008.

    --  Participating in $150 million syndicate financing for The
        Generations Network, Inc., an online network of family history
        Web sites. Hercules provided $17.5 million in debt and
        $500,000 equity capital in December 2007.

    --  Extending $20 million of venture debt to WildTangent, one of
        the leading online game networks, in November 2007.

    --  Participating in $85 million syndicate financing for Zayo
        Bandwidth, a regional provider of fiber based bandwidth
        services. Hercules provided $25 million of debt financing in
        November 2007.

Hercules also noted that, since 2003, 12 portfolio companies have been acquired or completed an IPO, thereby providing Hercules' portfolio companies with efficient exit paths and liquidity.

"This milestone achievement demonstrates Hercules' continued success and leadership in the venture capital community coupled with our firm's growing brand awareness," said Manuel A. Henriquez, co-founder, chairman and chief executive officer of Hercules. "Hercules continues to experience growth despite the current conditions surrounding the financial services industry. The company's unique positioning within the venture capital community allows Hercules to continue to develop a strong pipeline and provide needed growth financing to companies in the technology and life sciences fields."

"In addition, while concerns continue to loom over today's IPO market, venture backed companies' M&A activities have proven to offer a clearer and more successful exit path for many of our portfolio companies," Henriquez added. "We look forward to continue supporting the growth and development of other emerging growth companies in order to help them reach important milestones."
