WESTFORD, MA---Feb 11, 2002--- Teradyne's [NYSE:TER] Assembly Test Division, a global leader in electronics testing and production solutions, announced today that Sun Microsystems has selected GR Force/SCE™ for inclusion in Sun Microsystems' discrete manufacturing solution. The announcement was made at the ARC Advisory Group's Manufacturing Strategies for the Plant Floor Forum, in Orlando, Florida.

Sun's solution is a comprehensive offering to meet the needs of discrete manufacturers worldwide. GR Force/SCE provides the supply chain execution functionality for Sun's offering. GR Force/SCE is a high performance, high availability collaborative manufacturing execution system. It provides up-to-the-minute production information that enhances customer responsiveness and increases manufacturing efficiency to optimize collaborative manufacturing across a distributed, international, multi-company supply chain.

"Leveraging Teradyne for Sun's manufacturing solution makes sense, since as a customer, Sun has been using their supply chain execution solutions for some time," said William Gerould, group manager discrete manufacturing at Sun Microsystems. "This latest version of GR Force/SCE, 100% built from the ground up using Sun's JavaTM 2 Platform, Enterprise Edition (J2EE™) technology, should provide Sun as well as our manufacturing partners and customers with all the benefits of the Java platform right on the factory floor."

GR Force/SCE software helps manufacturers of highly engineered complex products meet their business objective of minimizing inventory by providing real-time shop floor information to manufacturers and their partners via the Internet. GR Force/SCE also increases manufacturing throughput by identifying production bottlenecks in real-time, and it decreases time to market by electronically managing engineering changes.

"We are very excited to be working with Sun in the discrete manufacturing sector," said Ron Lindell, manager of ATD's Supply Chain Software business unit. "By upgrading their supply chain execution infrastructure to GR Force/SCE, discrete manufacturers will be able to exercise much greater control over their critical manufacturing activities and become significantly more efficient and cost effective."

GR Force/SCE is an open industry standards based enterprise solution that easily integrates with other factory and corporate information systems using XML interfaces. It provides the lowest total cost of ownership through a browser based thin-client and a Java 2 Enterprise Edition (J2EE) compliant application server. GR Force/SCE enables management by exception by monitoring system variables such as statistical process control parameters and automatically notifying people and supply chain event management systems when a threshold is crossed on the factory floor.
