MAINSOURCE Appoints Independent Board of Directors

Ottawa, Ont.—September 22, 1999—MAINSOURCE Software Corporation today announced completion of the formation of an independent Board of Directors with the appointment of Robert Ashe, Deborah Weinstein and Claude Haw. Robert Ashe, Senior Vice President, Worldwide Customer Services at Cognos Incorporated, has led the charge for more than 15 years in the enterprise software market. Deborah Weinstein is a senior partner at LaBarge Weinstein and has considerable experience in guiding emerging technology companies. Claude Haw has been at Newbridge Networks Corporation for the past 11 years, most recently as Vice President of Business Development where he was responsible for the highly successful Affiliated-company program which included a portfolio of more than 15 technology start-up companies. Claude also becomes Chairman of the Board for MAINSOURCE.

“We are very pleased to have attracted these strong industry players to complement the MAINSOURCE team. They will help to guide us through the planned rapid growth phase for the company”, said Randy Senske, President, CEO and Founder. The Board of Directors also includes Randy Senske and Dan Roy, Executive Vice President. Paul Duff, Vice President, Business Development and Founder serves as Secretary for the company.

“MAINSOURCE is extremely well positioned to take advantage of the high growth in deployment of Web-based information systems, with their unique Level 7 information delivery architecture and products, that are capable of addressing the complexity demanded by today’s content management solutions,” remarked Rob Ashe. “I’m pleased to bring my knowledge of delivering strong enterprise software solutions to help the company attain its goals”.

“It is great to be able to join the Board of a start-up that has both a seasoned management team with more than 150 years of combined industry experience and a sophisticated product which is already shipping”, said Deborah Weinstein. “This is not a typical start-up.”

“I was attracted to MAINSOURCE because of the tremendous market size and opportunity,” added Claude Haw. “Every enterprise, ISP (Internet Service Provider) and ASP (Application Service Provider) understands the need to effectively manage their information and content needs. Many are only now realizing that they will need a highly scalable, distributed and robust solution to meet the requirements of their customers. MAINSOURCE has the right product at the right time in my opinion.”

MAINSOURCE expects to close a financing round of US $2 million in October to fuel the planned growth in R&D, implement an aggressive sales and marketing campaign and position the company to become the dominant solution provider in this explosive web content management market.
