Compatible Systems Inks Installation and Support Pact with Data General; On-Site Support Program Now Available for Industry-Leading IntraPort VPN Line.

BOULDER, Colo.--(BUSINESS WIRE)--July 12, 1999--

Compatible Systems Corporation today announced that it has signed an agreement with Data General Corporation (NYSE:DGN) of Westboro, Mass. under which Data General will perform on-site installation and maintenance of Compatible Systems' award-winning IntraPort family of VPN Access Servers.

The On-Site Support Program (OSSP) is an option available to customers of the Compatible Systems Total Care Support Program (TCSP), the company's premium support offering.

"We are the industry leader in hardware-based VPNs," said Matt McConnell, president and CEO of Compatible Systems Corporation. "Our IntraPort products are getting a great reception at Fortune 2500 enterprise accounts and Network Service Providers (NSPs). These customers have consistently asked for an on-site installation and maintenance program. Now we're partnering with Data General, one of the most respected names in IT support services, to provide that capability."

The Total Care Support Program provides round-the-clock access to Compatible Systems' support staff. When a TCSP customer with the OSSP option requires on-site installation or maintenance, Compatible Systems will notify Data General to dispatch a trained Data General technician to the customer site from one of more than 270 Data General support centers located throughout the world.

"No matter what the reach of the enterprise or service provider network, Data General has the means to provide quality on-site maintenance," says Mike Mancuso, vice president, US sales and support, at Data General. "Virtual Private Networks deliver great power and flexibility. We can help companies get the VPN running quickly and smoothly, just about anywhere that Compatible Systems products are sold."

While Compatible Systems will continue to include its no-cost telephone and web-based Integrated Support Package with every product, the Total Care Support Program with the On-Site Support Program option provides additional fee-based services for customers who require on-site installation and maintenance support. Under the program, a qualified service technician can be on the customer's site within just a few hours in the U.S., Canada, much of Western Europe and elsewhere.

"Our customers are making significant investments in virtual private networking," McConnell adds. "The On-Site Service Program is just another way for us to help ensure that these customers get the maximum return on their investments."
