MatrixOne Releases Synchronicity Developer Suite V4.1, Increases Productivity and Reduces Cost of Developing Semiconductors

Westford, Mass. - November 1, 2004 - MatrixOne, Inc. (NASDAQ: MONE), a leading provider of collaborative product lifecycle management (PLM) solutions for the value chainTM, today announced the availability of its Synchronicity® Developer Suite™ V4.1. The Synchronicity Developer Suite includes ProjectSync®, which raises design predictability with multi-site project-based issue tracking and communications, and DesignSync®, which makes design data available to the entire project team, no matter where they are located, in a safe, efficient, managed manner. Developer Suite V4.1 introduces a new DesignSync package, DesignSync CTS™ (Custom Type System). DesignSync CTS allows customers to extend DesignSync's core EDA Data Awareness™ and create a plug-in to recognize and manage data from other EDA tools that are not supported out of the box.

MatrixOne is the only semiconductor design data management provider that offers production-level integrations to multiple data formats from leading EDA vendors such as Cadence® OpenAccess, Cadence CDBA, and Synopsys® Milkyway™. With the addition of DesignSync CTS, the Synchronicity Developer Suite now has the ability to interface to any EDA tool, even customer proprietary tools.

Developer Suite V4.1 is the first Synchronicity-based product release since Synchronicity was acquired by MatrixOne in August of this year and demonstrates MatrixOne's dedication to extending and enhancing the Synchronicity product line. Future product releases will further extend the capabilities of the two product lines and add compelling new solutions for semiconductor design data management to the MatrixOne solutions portfolio.

"Executives in semiconductor companies are being forced to radically change the way they delivery new products to the market. Today's increased competition, the need to dramatically reduce product cycle times and cost and the challenges of a global and distributed product development environment have created the need for breakthrough design, collaboration and management solutions for the semiconductor industry," said Mark F. O'Connell, President and Chief Executive Officer of MatrixOne. "The new release of MatrixOne's Synchronicity Developer Suite 4.1 brings to market the latest advances in collaborative solutions to provide semiconductor companies with the competitive advantage to achieve their time-to-market objectives and drive growth through innovation."

Developer Suite V4.1 is also the only data management solution to provide self-updating data mirrors. DesignSync mirrors provide semiconductor development teams shared access to dynamically managed design data, which enables them to collaborate in real-time while saving dramatic amounts of file space and system network resources. Developer Suite V4.1 also introduces a tiered mirror structure that enables primary mirrors to populate data to secondary mirrors.

This configuration dramatically reduces network resources required to develop semiconductors in a distributed development environment. This further automates and accelerates the ability to get design data to teams in locations throughout the world while further reducing the amount of network traffic. As part of the self-updating, tiered architecture, DesignSync provides a web-based single point of creation and management for the self-updating mirrors which contributes to Developer Suite's low system administration overhead.

Developer Suite V4.1 also introduces revolutionary SmartVault™ technology, which automatically optimizes and manages data storage decisions for the engineer. By merely defining some simple thresholds, the storage format selection and conversions are automatically handled by DesignSync. This enables consistent application of data format types and policies and eliminates the need for the user to perform the data conversion. This results in major savings in storage resources and valuable developer time.

In addition, Developer Suite V4.1 bundles a new version of ProjectSync, which raises design predictability with multi-site project and issue tracking and communications no matter where they are located. Included amongst numerous enhancements are the ability to view file attachments directly from the datasheet, email notifications inn HTML, the ability to share saved queries, and numerous other labor saving collaborative capabilities.

The Developer Suite continues to be supported on all major platforms including Solaris, HP-UX, Windows, and RedHat Linux including Red Hat Enterprise Edition.

Pricing and Availability
Developer Suite V4.1 is broadly available now and is priced from $4500 per user depending on configuration.
