Ottawa, Ont.— September 2, 1999 — MAINSOURCE Software Corporation today announced that Daniel (Dan) Roy has joined the company to head up marketing, sales and channel development. Dan joins the company from Newbridge Networks Corporation where he held various senior management positions which included launching Newbridge into the frame relay and packet switching business and the implementation of the firm's affiliate and technology partnering programs.

Also joining the company as Vice President, Healthcare Business Development is Dr. Christopher Skinner.

" We are very excited about the addition of Dan and Chris to our team and look forward to continued growth of the company with them onboard", remarked Randy Senske, President and CEO, MAINSOURCE Software Corporation. "They complement the existing senior team comprising myself, Paul Duff, Vice President Business Development and Brian Murphy, CFO and Treasurer. The key executives are now in place to support the strong growth anticipated for the MAINSOURCE team to 100+ people from the current team of 20."

"What impressed me about MAINSOURCE was its understanding of production class information systems and the product architecture", said Dan Roy. "A new paradigm for the Internet is developing that will enable the next generation of web based business applications. With its state-of-the-art content management solution built around Level 7 Information Switching technology, the company is well positioned to take the lead in this area. Level 7 Information Switches handle information as objects that are routed intelligently based on their attributes. By integrating the MAINSOURCE content management solution into the web, it is transformed into a virtual, global object database enabling any type of information to be managed in a highly structured and efficient manner that can be scaled to support unlimited-sized systems. The impact on Internet Service Providers (ISPs), Application Service Providers (ASPs) and the Enterprise promises to be very significant and this is what attracted me to MAINSOURCE", explained Mr. Roy.

Dr. Skinner, who is also a practicing neurologist, noted that "This technology will revolutionize how we deliver health care information to clinical providers using secure web access. This approach allows health care organizations to share information in a secure fashion without disrupting their existing infrastructures. It also frees healthcare institutions from being dependent on single vendor solutions and is a major enabler for regionalization of healthcare resources across Canada and North America."
