Mangosoft Reaches Milestone And Signs 100th Var To Reseller And Solutions Provider Program

Cachelink Pro Software Greatly Speeds Up Web Access For Any Size Organization; Gives VARs a Unique, Cost-effective Product

Westborough, MA - December 15, 2000: Mangosoft, Inc. (Nasdaq BB: MGOF), developers of Internet business enabling software and services, today announced that it has signed its 100th value-added reseller (VAR) to the Mangosoft Platinum Partner Program. Launched in August of this year, the VAR program is focused on solutions providers who can rapidly integrate Mangosoft's (R) Pro Web caching software into solutions for small-to-mid size businesses, schools, and other organizations looking to maximize Internet access speed.

Cachelink Pro is the only software-based, LAN-wide Web cache product designed to significantly increase the speed and performance of Internet access for any size organization. Solution providers combine Cachelink software with networking hardware for a powerful, easy-to-administer solution that produces immediate results and requires no additional training to use.

The national program includes large and small resellers who have an intimate knowledge of the business landscape in their regions and are focused on the integration of computing solutions such as Mangosoft's Cachelink Pro software. A sampling of Mangosoft's resellers includes: Integrated IT Solutions, Aegis Associates, CEJ Computer Business, Needle Technology, Quest, RetroFit Technologies, and Scion Computers.

"The response to the program has been tremendous," said Jim Yearick, product manager at Mangosoft for Cachelink Pro. "As VAR's continue to incorporate Cachelink Pro into their service offerings, they can provide their customers significantly better Internet performance without the expense of upgrading service levels at their ISP's. That's a very strong value proposition for them to offer."

Mangosoft recently received an order for 800 Cachelink licenses from a systems integrator in California who will install the product into a Michigan school system.

The rapid success of the Mangosoft program is fueled by the distribution agreement signed earlier this year with Marketlink Technologies, LLC, a national outsource sales and marketing organization for the computer channel. Under the agreement, Marketlink markets and sells Mangosoft's Cachelink Pro Web caching software to value-added resellers (VARs), independent software vendors (ISVs), integrators, and other solution providers.

Furthering its distribution efforts, Mangosoft also announced that 3Com Corporation expects to begin shipping its (R) LAN Modem products with Cachelink Pro by the end of the year. The two companies announced an agreement earlier in the year to combine products and allow small businesses to accelerate Internet access without the cost of higher-speed Internet access.
