SpaceVest Portfolio Companies to Present at Mid-Atlantic Venture Association's Capital Connection Event; Four Companies Illustrate Venture Capital Firm's Diversified Investment Approach.

RESTON, Va. -- SpaceVest, a venture capital firm that invests in companies leveraging advanced technologies to provide solutions for rapidly growing markets, today announced that four of its portfolio companies will be presenting at Capital Connection 2005, the region's top venue for bringing together entrepreneurs and venture investors. The four companies (Arc Second, Inc., Telarix, Nextreme Thermal Solutions, and Blue Ridge Networks) represent the diversity of the venture capital firm's investments and expertise in satellite, communications, semiconductor and networking technologies.

"These companies beat out a pool of highly-qualified applicants because the selection committee believed that they were attractive investment candidates," says Rich Harris, managing director at SpaceVest. "Capital Connection uses the same selection criteria as a venture capitalist would use when looking at companies for potential investment. Their selection also shows that these sectors are highly attractive to investors."

The four companies will be presenting their business plans and discussing their products with some of the nation's most prominent venture investors. Arc Second, Inc., provides proprietary Indoor GPS-based position determination solutions for applications in multiple industries. Telarix delivers the leading Interconnect Business Optimization software solution, which provides telecommunications companies the ability to easily manage costs and drive profitability on their interconnect networks. Blue Ridge Networks is a leading provider of high security Virtual Private Network (VPN) appliances and managed services. Nextreme Thermal Solutions created a thin film thermoelectric materials technology for the semiconductor chip cooling market.

"The MAVA selection process is a rigorous one, and we're honored to be a part of this esteemed venture fair," says Nextreme CEO Jesko von Windheim. "We look forward to the opportunity to showcase our offering."

Produced by the Mid-Atlantic Venture Association (MAVA), Capital Connection 2005 is one of the nation's most successful and influential venture events. Over the years, MAVA venture fairs have helped to shape the region's entrepreneurial economy, generating more than $2.4 billion of venture investments in the presenting companies.
