Comprehensive solution capitalizes on strengths of mixed Windows NT Workstation 4.0 and Windows NT Server 4.0 and UNIX® environment

Waterloo, ON, November 10^th, 1998: Mortice Kern Systems Inc. (MKS) (TSE:MKX) today announced a solution to finally bring to an end the pain corporations suffer in trying to fit together disparate Windows NT Workstation 4.0 and Windows NT Server 4.0 and UNIX operating systems.

The MKS Toolkit^® Update Edition is targeted directly at corporate Windows NT systems administrators and developers who suffer the pains of working with two essential, but very different computing environments — Windows NT and UNIX. The MKS offering is an upsell to the Microsoft Windows NT Services for UNIX Add-On Pack, also officially released today by Microsoft Corporation® (Nasdaq:MSFT). The availability of both products brings to corporate customers unsurpassed UNIX programming and systems management capabilities on the Windows NT platform, enabling companies to finally knit together the two operating systems.

"Our enterprise customers are deploying Windows NT Workstation and Windows NT Server alongside UNIX systems and they are grappling with the issue of total enterprise interoperability. Through the delivery of our Windows NT Services for UNIX Add-On Pack, Microsoft has chosen to tackle this challenge head on, solving customer problems today. MKS extends the Microsoft offering further by providing additional programming and management capabilities," says Frank Artale, general manager for enterprise systems management at Microsoft Corp.

"Customers such as Lucent, Siemens, Intel and Salomon Smith Barney have all experienced the challenge of knitting together Windows NT and UNIX in the enterprise, and all of these companies have turned to MKS to provide an answer. No one else in the market can match MKS's history and experience in providing the most powerful and sophisticated solution to address the technological challenge of interoperability," says Randall Howard, MKS chairman and CEO. "Microsoft's attention to the issue of enterprise interoperability, with the release of the Windows NT Services for UNIX, now gives these customers a readily available and completely workable solution. MKS is very pleased to work with Microsoft to extend the solution for customers that much further."
