LOUISVILLE, Kentucky--(BUSINESS WIRE)--July 25, 2000

Darwin Networks, a leading provider of high-speed Internet access and network solutions, was recently selected to provide services for the entire portfolio of properties owned and operated by PS Business Parks, Inc. (AMEX: PSB).

PS Business Parks is a fully integrated, self-managed real estate investment trust (REIT) with more than 150 office park facilities located in several Southern, Midwestern and Western states, concentrated in California, Texas, Oregon, Virginia and Maryland. These facilities are used for manufacturing, assembly, storage, warehousing, distribution, research and development activities.

Darwin Networks will service the PS Business Parks properties using its proven high-speed wireless, wireline and satellite technologies, providing each individual client with cost-effective, dependable and secure Wide Area Network (WAN) solutions and high-speed Internet access.

"Our selection of Darwin Networks is another example of our continued commitment to provide our tenants with access to services that support their long-term growth," said Jeff Reinstein, vice president of PS Business Parks. "What sets Darwin Networks apart from other Internet access providers is its willingness to provide services in circumstances where other companies would not."

Within the commercial market, Darwin Networks concentrates on small and mid-sized enterprises that need the same high-speed connectivity as larger organizations, but don't have the resources to secure dedicated fiber optic connections. As economical alternatives for the nation's millions of small to mid-sized businesses, Darwin Networks offers fixed wireless, wireline (e.g. DSL, T1) and even satellite-based solutions.

"Our partnership with PS Business Parks further solidifies its reputation as an innovative commercial property company focused on the future of technology," said Joel Coleman, president of Darwin Networks' Commercial Division. "They recognize that high-speed Internet access is essential to businesses in the new electronic economy, and that our guaranteed services will help keep them ahead of their competition."
