MONE Matrixone (MM)

Industry-Specific Solutions Help Semiconductor Companies Integrate Electronic Design and Product Management Processes to Improve Information Sharing, Collaboration and Time-to-Market MatrixOne, Inc. (NASDAQ: MONE), a leading provider of collaborative product lifecycle management (PLM) solutions for the value chain(TM), announced today that it will be demonstrating its semiconductor industry-specific PLM solutions at the annual DATE 2006 conference, Europe's largest forum for the electronic design engineering community. MatrixOne will be located at Booth # B9 during the show, which is taking place this week (March 6-10, 2006) at ICM, MESSE in Munich, Germany. At the show, visitors to the MatrixOne booth will be able to see demonstrations of its latest industry-specific PLM Accelerators--the MatrixOne Semiconductor Accelerator for Enterprise Project Management(TM) and the MatrixOne Semiconductor Accelerator for Design-to-Manufacturing(TM). Both of these solutions enable semiconductor companies and IC design organizations to address the complex business challenges involved with taking large scale development projects from conceptual design through to the manufacturing hand-off. These solutions allow semiconductor manufacturers to rapidly implement industry-specific best practices, with a lower risk and a faster return on investment than other PLM solutions that have not been tailored to the specific needs of semiconductor companies and design organizations. In addition, MatrixOne will also be showing the MatrixOne Synchronicity(R) Developer Suite(TM) solution, which is an advanced design data management environment already in use at 12 of the world's top 15 semiconductor companies. Developer Suite provides designers with improved performance and support for a broad range of EDA applications and operating platforms, facilitating global, multi-site development that can lower cycle times, increase quality and improve return on product development. -0- *T What: MatrixOne representatives will be on-site at the annual DATE 2006 show to demonstrate the latest semiconductor-specific electronic design/product lifecycle management solutions.
