DSL.net Receives Strategic Investment from MegaPath with Option to Acquire DSL.net.

WALLINGFORD, Conn. -- DSL.net, Inc. (OTCBB: DSLN), a leading nationwide provider of broadband communications services to businesses, today announced that MegaPath Inc., a privately held company and leading provider of Virtual Private Network (VPN) solutions and other managed IP services to businesses nationwide, has made a strategic investment in DSL.net which will allow MegaPath to acquire substantially all of the equity of DSL.net upon receiving regulatory and shareholder approvals.

"DSL.net is known for offering its broadband customers high performance and reliability, over our own network, through innovative service offerings designed to increase our customers' productivity and business profitability," said David Struwas, Chief Executive Officer of DSL.net. "By combining DSL.net's and MegaPath's infrastructure and service offerings, we will be in a position to offer customers outstanding network performance and the most comprehensive set of managed IP services available anywhere. This is great news for both companies' customers."

DSL.net currently offers services via its own facilities in over 350 collocations located in Vermont, New Hampshire, Massachusetts, Connecticut, Pennsylvania, Rhode Island, New York, New Jersey, Delaware, Maryland, Virginia and Washington, D.C.

As the leading IP Managed Service Provider (MSP) in North America, MegaPath can offer DSL.net customers expanded broadband coverage throughout the U.S. and Canada. MegaPath can also provide a full range of integrated security, IP telephony, remote access and site-to-site IP VPN services to augment DSL.net's network services. The acquisition, once completed, will give MegaPath access to DSL.net's broadband facilities and network expertise to deliver these services throughout the Northeast and Mid-Atlantic regions, which have the highest concentration of businesses in the United States.

"This strategic investment gives us the opportunity to accelerate MegaPath's growth and improve its profitability, while also providing us with greater control over the quality of service we offer our customers," said Craig Young, Chairman and Chief Executive Officer of MegaPath. "We are eager to help DSL.net customers grow their businesses by leveraging our wide array of managed IP services, expanded network reach, and additional operational and engineering resources. Moreover, the combined company would offer the financial strength and market leadership that enterprise customers look for when selecting a service provider to manage their business-critical communications."

The strategic investment by MegaPath was funded in part by certain of MegaPath's existing investors, which include Fidelity Ventures, Rho Ventures, U.S. Venture Partners, Columbia Capital, Trident Capital and Boston Millennia Partners.

Both companies will continue to operate separately in a "business as usual" manner until the acquisition occurs, which is expected to happen on or about year end, although this date is subject to change.
