MatrixOne Integrates MitemView to Improve Legacy System Communication and Collaboration

Software Integration Improves Access to Data and Transactions Through the Value Chain to Increase Productivity and Reduce Costs

Menlo Park, Calif. and Chelmsford, Mass. - March 29, 2001 - MatrixOne, Inc. (NASDAQ: MONE), the first in Intelligent Collaborative Commerce^TM, and MITEM Corporation, a leading provider of legacy integration software for conducting real-time e-Business, today announced the integration of MitemView® into MatrixOne's eMatrix^TM platform. This agreement will enable MatrixOne customers to easily access data and transactions from virtually any legacy system in a completely non-invasive way, requiring no changes or additions to existing systems and reducing both the cost and implementation time.

MatrixOne's eMatrix framework and business applications improve the flow of information, integrate business processes and facilitate collaboration among partners, suppliers and customers. The addition of MitemView to the eMatrix platform will enable eMatrix users and other trading partners to communicate effectively and efficiently regardless of legacy enterprise applications, development languages or database structures in place.

Additionally, the MITEM Adaplet provides true real-time application integration, providing users with the most current information rather than out-of-date batch updates or data from day-old replicated databases. This provides more accurate information to the user, increasing productivity and ensuring reliable decision processing of eMatrix data.

"As customers seek to improve productivity and reliable data processing across multiple legacy systems, it will become increasingly important to employ software that allows for easy access to data and transactions," said Mark Bierschied, director of integrated e-Business solutions for MatrixOne. "This integration with MitemView ensures that current or prospective MatrixOne customers can achieve easy access to information with minimum disruption to their existing business processes."

The integration of any character-based application into the eMatrix platform is now made possible because MitemView functions independently of hardware, operating systems and database structures. Rather, the software uses the existing application interface - typically a terminal data stream - as a high-speed channel to the existing business logic. As a result, eMatrix customers enjoy more flexibility in the applications they can use and decreased maintenance costs, as well as increased return on investment on their legacy systems.

"MITEM Corporation is excited to contribute to the success of MatrixOne's eMatrix collaborative commerce solution," said Martin Fincham, MITEM's vice president of marketing. "This pre-built and tested integration between MitemView and eMatrix will improve efficiency and profitability throughout the value chain."
