Covad Positioned to Gain From Expansion of Business DSL; Research Firm Gartner Names Covad Among Business DSL Market Leaders.

SAN JOSE, Calif. -- Covad Communications Group, Inc. (AMEX:DVW), a leading national provider of integrated voice and data communications, today announced its inclusion in a report from industry research firm Gartner, Inc. titled "Business-Class Digital Subscriber Line Services in North America." In the report, Gartner names Covad as one of eight business-class DSL market leaders in the US. Covad offers a broad portfolio of DSL solutions for businesses and is building what will be the nation's largest next-generation DSL network, scheduled for completion later this year.

"In my eight years at Covad I've seen the focus of our DSL business evolve from consumer offers for wholesale partners to business-class solutions sold directly," said David McMorrow, Covad executive vice president of sales and marketing. "There has always been a strong market for business-class DSL and Covad is better positioned than ever to capture that demand and grow our revenues."

Gartner forecasts the number of business-class DSL lines in service to grow from more than 4.3 million at the end of 2005 to about 11.85 million by the end of 2010. Part of this growth is attributed to the emergence of ADSL 2+, a next-generation DSL technology that Covad is deploying in 11 markets nationwide.

"Covad is a DSL pioneer and one of a small number of leaders in the DSL market in the U.S.," said Dan O'Connell, research director at Gartner. "The deployment of ADSL 2+ positions Covad to remain among the top DSL providers going forward."

By the end of 2006, Covad will have the capability to offer ADSL 2+ in Atlanta, Chicago, Los Angeles, New York, Miami, Philadelphia, San Diego and Washington, DC. Those markets join San Francisco, San Jose, Seattle and Dallas, where Covad's next generation network is already in service.
