Seminar to Discuss How PLM Solutions Can Help Semiconductor Companies Meet New Technology Challenges and Speed Time-to-Market for New Innovations

WESTFORD, Mass.—(BUSINESS WIRE)—April 3, 2006— MatrixOne, Inc. (NASDAQ: MONE), a leading provider of collaborative product lifecycle management (PLM) solutions for the value chain(TM), today announced that it will be hosting a free seminar focused on the product development challenges specifically facing semiconductor companies in India. The seminar is taking place on April 6th at the Leela Palace Hotel in Bangalore, and is jointly sponsored by D'GIPRO, the leading EDA tools solutions provider in India. The seminar will analyze how PLM solutions can help companies in this industry better manage challenges like the move to 65nm design, system-on-a-chip (SOC) development, globally dispersed design teams and the change in cycle times brought on by increasing manufacturer and consumer demand.

Questions to be addressed include:

-- Does your design team currently have a unified way to manage all design data and project issues?

-- How are your design teams deploying a best practices release methodology?

-- Could the team benefit if you established a common standard for data management and project information?

-- Would your design teams be able to improve their efficiency if you could guarantee they are working with the up-to-date releases of design data, IP and libraries?

-- Would your design teams be able to track down and rapidly fix inadvertent errors if all the changes and decisions made by the extended team were completely auditable and captured by your system--providing what-when-why information via a simple browser-based interface?

What:        Free seminar entitled: 
             "Maximizing Return on Collaborative Innovation."
