Westford, Mass., May 26, 2005  - MatrixOne, Inc. (NASDAQ: MONEE), a leading provider of collaborative product lifecycle management (PLM) solutions for the value chain , today announced the successful completion of this year's Global Customer Conference (GCC 2005) in Nashville, TN. Throughout the conference, over 40 MatrixOne customers presented their company's PLM case studies to several hundred conference attendees. Many of the sessions focused on how MatrixOne PLM provides a "return on innovation," helping product companies drive top-line revenue growth and bottom-line profitability.

The conference kicked off with an executive panel composed of industry-leaders and MatrixOne customers including, Johnson & Johnson Consumer Products Company, Sony Ericsson and Trane, who all shared their experiences in using MatrixOne's PLM solutions to address their most critical product development challenges-reducing design and development costs, extending design expertise across the enterprise, improving product quality and accelerating time to market.

In addition, in a series of presentations entitled "I'm an Innovator," speakers such as Boeing Australia Ltd., Keppel Corporation, Nortel, Phillips Semiconductor and Schlumberger identified the powerful techniques they have employed in conjunction with MatrixOne's PLM solutions to maximize product development through-out the product lifecycle. Although each company faced its own unique internal challenges and market requirements, each highlighted how MatrixOne provides the ideal product development platform and focused solutions necessary to manage the increasingly complex world of product development.

"These global champions are examples of how to drive innovation throughout the product development process, while delivering on increasingly complex customer expectations," said Mark F. O'Connell, president and CEO of MatrixOne, and a keynote speaker at the event. "GCC is one of the most valuable ways for us to hear the voice of the customer and then work together to deliver on their vision."

Bruce Richardson, chief research officer for AMR Research, delivered a keynote presentation entitled, "Welcome to the Innovation Era," discussing 10 bold ideas for the PLM market-and challenging an audience full of manufacturing leaders to focus on new markets for their products, to pursue product differentiation wherever possible and to leverage globalization and the supply chain for real growth opportunities.

In addition, the conference featured a variety of sessions and forums focusing on industries such as aerospace & defense, automotive, consumer products, footwear & apparel, high tech/electronics, machinery/industrial, medical devices and semiconductors. In these sessions and forums MatrixOne customers including Agilent, LSI Logic, New Balance, Possis Medical, Procter & Gamble and many others discussed specific industry challenges and shared their experiences in overcoming them.
