Hercules Technology's Portfolio Company, Interwise, is To Be Acquired by AT&T for $121 Million, Marking the Sixth Announced Acquisition of a Hercules Portfolio Company in 2007

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 noted that its portfolio company, Interwise, a leading global provider of voice, Web and video conferencing services to businesses, has entered into an agreement to be acquired by AT&T Inc. (NYSE: T) for approximately $121 million in cash. The announcement of this transaction marks the sixth acquisition of one of Hercules' portfolio companies in 2007.

Hercules initially provided $3 million in venture debt financing to Interwise in September 2005 thus allowing the company access to growth capital without the dilutive effects of traditional venture capital. In addition, Hercules expects to report a realized gain from its warrant position in its fourth quarter financial results.

"The agreement of the acquisition of Interwise clearly demonstrates Hercules' ability to help our portfolio companies to grow and achieve important milestones through our extensive growth capital financing solutions as well as provide value to our investors through our warrant positions in portfolio companies," said Manuel A. Henriquez, co-founder, chairman and chief executive officer of Hercules. "We congratulate Interwise on this agreement to be acquired and the future opportunities it will bring to the company."

AT&T announced its agreement to acquire Interwise through one of its subsidiaries on October 1, 2007. The transaction, which is expected to close in the fourth quarter, strategically aligns Interwise's innovative IP-based conferencing and collaboration solution with AT&T's enterprise networking, communications and collaboration services, global MPLS-based IP network and its industry-leading conferencing portfolio of services.

Following the acquisition, the company will operate as a business unit within AT&T Global Business Services, which serves the largest enterprises around the world and is led by Group President Ronald E. Spears. AT&T expects to retain Interwise's management team and its domestic and international operations, including its R&D center in Israel.
