SAN JOSE, Calif.--(BUSINESS WIRE)--May 16, 2002

Establishes new sales offices to leverage

market opportunities and meet business needs

Corrigent Systems, today announced the relocation of its corporate headquarters and the opening of two new sales offices in Texas and Massachusetts.

Founded in September 2000, Corrigent's original headquarters was located in San Francisco, California, but due to recent corporate expansion and market opportunities, the company has relocated to San Jose, California.

"Corrigent Systems is continuing to gain traction with our customer base," said Shane Eleniak, vice president of product management and sales. "The relocation of our corporate headquarters and the opening of our two new sales offices will allow us to better serve our customers' needs and continue the expansion of our organization."

A leading provider of metro-optical transport products, Corrigent Systems has developed the CM-100(TM) series, a carrier-class, packet-centric optical transport solution utilizing Resilient Packet Ring (RPR) technology. RPR, a new MAC layer technology being standardized in the IEEE (802.17 Workgroup), was designed to combine SONET carrier-class functionalities with Ethernet's high bandwidth utilization and granularity. It enables a genuine alternative to SONET transport for packet networks, providing carriers with resiliency, fast protection and restoration comparable to those of SONET networks. Additionally, it offers a packet-centric bandwidth management scheme that delivers a cost effective transport solution over ring based topologies.

Corrigent's innovative network architecture offers a complete transport solution to carriers by supporting a highly efficient use of network resources, thus overwhelmingly reducing capital costs. Because it easily fits into today's operational processes, it eliminates the operational hurdle and associated costs, which is often a major barrier that carriers face when introducing packet-centric transport technologies to their existing SONET networks.

"By utilizing the best of RPR and MPLS technologies, Corrigent's CM-100 series offers the most optimized solution for carriers today," said Eleniak.
