Telelogic Lands First Customer for Tau®/Developer(TM) and Tau/Architect(TM) Prior to General Availability -Hughes Network Systems Will Use Telelogic's New Tools to Develop Satellite and Wireless Communications Products- 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 Hughes Network Systems, the world's leading provider of broadband satellite network solutions for businesses and consumers, has purchased Telelogic Tau/Developer and Telelogic Tau/Architect prior to general availability. Both Tau/Architect and Tau/Developer were launched earlier today. Along with Tau/Tester(TM), which was introduced in May 2002, these products represent Telelogic's next generation of development tools, known as Tau Generation2. With Tau Generation2 companies can for the first time deploy across the entire enterprise an integrated, multi-user visual tool solution that supports and accelerates the entire application development lifecycle - from system analysis and specification to real-time software design, implementation and testing - all within the same state-of-the-art, productivity-enhancing development environment. Using the Unified Modeling Language(TM) (UML(TM)) to visualize the development process, Tau/Developer and Tau/Architect enable significant increases in productivity to be realized compared to labor intensive manual programming approaches. "We were looking for an advanced UML-based modeling tool to aid in the development of our mobile satellite products," said Nigel Bartlett, Director of Wireless Communication Software at Hughes Network Systems. "Tau/Developer and Tau/Architect will enable our architects, systems engineers and software developers to improve the development process. We can use a single tool for analysis, design and auto code generation. Because the tools are based on open standards, they fit easily into our existing development environment." "As current users of our Tau UML Suite and Tau SDL Suite, Hughes Network Systems has already experienced first hand the productivity and quality benefits that advanced automated development tools can provide," said Anders Lidbeck, President and CEO of Telelogic. "With the introduction of Tau/Developer and Tau/Architect, Telelogic has once again raised the bar on productivity and quality. Hughes Network Systems has seen the potential benefits of deploying our new Tau Generation2 tools and we expect many other companies around the world involved in advanced systems and software development to do the same."

About Telelogic Tau/Developer Telelogic Tau/Developer is a stand-alone visual tool for UML-based design, analysis and development of advanced real-time applications. Targeted at software engineers, it can be easily integrated with Telelogic or other third-party products. Using Tau/Developer's model- driven approach and field-proven automatic application generation capabilities, software developers can shift their focus from traditional labor-intensive code-centric programming to high quality, high productivity development. About Telelogic Tau/Architect Tau/Architect is a modern, model-based system engineering tool for the analysis and specification of advanced systems. Tau/Architect supports comprehensive modeling of large and complex systems using UML, resulting in precise, easy-to-understand specifications.
