WASHINGTON, D.C., April 24, 2002 - Cogent Communications Group, Inc., (AMEX: COI) a Tier One, optical ISP announced today that it acquired a significant portion of the portfolio of real estate access agreements from OnSite Access, Inc., a BLEC communications provider that filed Chapter 11 in May, 2001 in the United States Bankruptcy Court for the Southern District of New York.

An overwhelming majority of the access agreements selected by Cogent pertain to buildings located in New York City. Also included are select buildings located in Dallas, Philadelphia, San Francisco, and Chicago.

"Having the ability to individually select building access agreements to perfectly complement our existing portfolio really adds value to this deal," said Dave Schaeffer, Chief Executive Officer, Cogent Communications. "Acquisitions such as this one really help to accelerate our business plan and shorten the length of time between initiating contact with the building owner and actually providing service to the owner's tenants."

The deal will add an additional 16 Million square feet to Cogent's portfolio of over 3,400 building access agreements totaling close to one billion square feet of space. The buildings selected from OnSite Access were all previously qualified as Cogent targets for high speed Internet access. Many of the buildings already have tenants that have placed orders with Cogent, but access agreements had yet to be negotiated with the owners.
