Business/Technology Editors

ANDOVER, Mass.--(BUSINESS WIRE)--April 20, 2000

-- Relationship Will Add Advanced Multi-Media Features And Boost

Performance For Both GeoDial Wholesale Access

and NaviOne Solution Suite --

NaviPath(TM), Inc., a majority-owned operating company of CMGI, Inc., today announced a strategic alliance with Akamai Technologies, Inc. (NASDAQ: AKAM). The agreement adds new capabilities and performance enhancements to The NaviPath Technology Platform, an innovative network architecture that is the foundation for NaviPath's GeoDial(TM) (wholesale access service) and NaviOne(TM) solution suite (branded services). In addition, NaviPath announced the release of GeoDial Version 4.

As a result of the relationship with Akamai, NaviPath will deploy Akamai's Web servers in key points of presence within the NaviPath network. By placing Akamai's servers in these key locations, and thus Akamai's leading EdgeAdvantage(TM) technology, NaviPath will improve its performance and reliability in delivering all forms of Web content, streaming media and applications from top Web properties to NaviPath's extensive base of wholesale and branded services' customers.

NaviPath will provide Akamai with fast and reliable Internet connectivity for improving the speed and performance of popular, high-bandwidth Web sites. NaviPath will also be among the first dial access networks to join Akamai's Accelerated Network Program. "Akamai is excited to join forces with NaviPath to provide enhanced Internet performance solutions," said George Conrades, Chairman & Chief Executive Officer of Akamai. "The combination of NaviPath's broad reaching access service and their extensive subscriber base provides Akamai with an ideal environment to speed delivery of Web content."

NaviPath & Akamai's Accelerated Network Program

Through Akamai's Accelerated Network Program, NaviPath, among other network providers and dial access services, has joined forces with Akamai to place Akamai servers in their network to improve Web performance to both dial and broadband subscribers. Unique to the Akamai and NaviPath relationship is the recognized value of deploying Akamai's technology within NaviPath's private transit Internet connectivity rather than that of traditional public peering. This approach provides Internet connectivity for customers that depend on the Internet as a strategic resource, enabling NaviPath to provide uninterrupted services and predictable pricing plans to its customers.

"Akamai is changing the way content, applications and streaming media are delivered on the Web, and many of the busiest sites are adopting the Akamai service for optimal performance," said TC Browne, Chief Executive Officer of NaviPath. "Our GeoDial access service and NaviOne solution suite will greatly benefit from the deployment of Akamai's servers throughout our high performance network."

GeoDial v.4 Introduced

Like its predecessor, version 4 of GeoDial leverages NaviPath's powerful network architecture to avoid Internet congestion, enabling ISPs to offer high-performance access services while at the same time lowering their costs per subscriber. The new features in GeoDial v.4 include:

--New Packet Filtering capabilities that enable NaviPath customers to apply custom filters to individual subscriber sessions.

--User Disconnect Utility that allows NaviPath customers to disconnect their subscribers on demand.

--Managed high speed "Tail Circuit" Services, an optional service whereby NaviPath provides, maintains and monitors the customer's high-speed connection to NaviPath's network.

"NaviPath continues to add powerful management capabilities to our GeoDial access service while maintaining price/performance leadership in the marketplace," said Brendon Howe, VP of marketing at NaviPath. "By including advanced management tools, new filtering capabilities and managed high speed connectivity- and backing them with guaranteed service level agreements -NaviPath continues to set the standard in wholesale access services."

Service Expansion

NaviPath estimates that its GeoDial access service now covers more than 85 percent of the US online major market population. In addition, coverage in Canada was launched this week. Along with superior Internet access services, NaviPath provides organizations with branded 24x7 customer service and support from its Network Management Center (NMC). Through the NMC, NaviPath proactively monitors network and systems components, subscriber connections and Internet connectivity on behalf of its clients and customers, and provides a second level of support for service requests and emergencies. In addition, NaviPath's online management tools supply network activity and subscriber usage information essential to customers' management capability.
