Telelogic Sells Additional Licenses of Tau®/Architect(TM) Prior to General Availability

Telelogic Sells Additional Licenses of Tau®/Architect(TM) Prior to General Availability - Cellon Predicts Substantial Quality Improvements from Using One Tool and One Language for All Development Activities - Malmö, Sweden and IRVINE, California- October 7, 2002 - Telelogic (Stockholm Exchange: TLOG), the leading global provider of solutions for advanced systems and software development, today announced that it has signed a license agreement with Cellon, the world's largest independent wireless design house. The agreement provides Cellon's engineers with access to Telelogic's new visual system engineering tool Tau/Architect, which was introduced today. The agreement also includes licenses of Telelogic DocExpress® for automated documentation. Tau/Architect is ideal for system engineers who want to model large and complex systems using an industry accepted visual language. This innovative tool is part of Telelogic's new Tau Generation2 family of products, which also includes Tau/Developer(TM) for real-time software development and Tau/Tester(TM) for automated software testing, which was introduced in May 2002. Cellon France - the French operating unit of Cellon International - selected Tau/Architect to help streamline its development environment and deploy a single-vendor development solution based on the Unified Modeling Langauge(TM) (UML(TM)). The company plans to utilize Tau/Architect in the design and development of wireless communication devices. "We were looking for a UML-based tool that would cover all development phases: system analysis, specification, modeling and implementation," said Pascal Breut, Software Director at Cellon. "Telelogic has a tremendous track record for providing powerful tools to the software industry, and our evaluations proved that not only did the new Tau/Architect meet all our requirements, it enabled us to replace a number of diverse tools with just this one tool." Tau/Architect supports the current industry-standard visual development language UML that is maintained by the Object Management Group(TM) (OMG(TM)). The tool also includes many of the advanced features proposed for the next major revision of the language known as UML 2.0. "We believe Tau/Architect will provide a number of crucial benefits," continued Mr. Breut at Cellon. "First, the tool methodology will help our teams focus on architecture and design issues at an early stage. Secondly, it will contribute to ensuring the reliability of our development process covering modeling, simulation and application generation. Thirdly, it provides one common, visual language for all users, which will improve communication and documentation. Finally, it embodies many of the features of the evolving UML 2.0, which ensures that Tau/Architect is a future-proof technology that our organization can grow with." "We are very proud that Telelogic Tau/Architect was selected by Cellon," said Ingemar Ljungdahl, Telelogic's Chief Technology Officer. "By leveraging the industry-standard language UML, with many of the capabilities of the evolving UML 2.0 proposal included, Tau/Architect provides tremendous benefits to modern development organizations in terms of productivity, quality and predictability."
