• Wind River Platform will meet National Security Agency's Highest Evaluation Assurance Certification Level--EAL 7
• Boeing's C-130AMP Scheduled to use Wind River's Safe and Secure Platform technology

ALAMEDA, Calif.--March 30, 2004--As part of its Safe and Secure Program, Wind River Systems, Inc. (Nasdaq: WIND), the global leader in device software optimization (DSO), today announced that it is partnering with Smiths Aerospace to extend Wind River Platform Safety Critical ARINC 653 to meet the National Security Agency's highest evaluation assurance certification level, EAL 7. Platform for Safety Critical ARINC 653 will further solidify Wind River's position as the leading provider of safe and secure systems for the military and aerospace industry.

By working with Smiths Aerospace, Wind River Platform for Safety Critical ARINC 653 with security certification will be used in Boeing's C-130 Avionics Modernization Program. Under the C-130 Avionics Modernization Program, Boeing will develop a modern, common cockpit avionics system for the approximately 500 C-130 transport aircraft in Air Force service.

"Developing a secure run-time environment that meets safety and security certifications is a significant development effort that requires expertise in project management, device software, safety and security. Smiths and Wind River have enjoyed a long history of collaborating together on projects and programs, and working toward EAL 7 security certification is the next step in this partnership," said Gerry Vossler, Director - Technology Development of Smiths Aerospace.

Wind River Platform for Safety Critical ARINC 653 will be based on a Multiple Independent Level Security (MILS) architecture, evaluated to the highest level in the Common Criteria process. A MILS environment is capable of housing and transferring data at varying security levels--secret, classified and unclassified--in a manner conformant with national security policies. A MILS environment also has secure partitioning, which gives customers the flexibility of adding applications at a later date, without having to go through the costly and time-consuming process of re-certifying the entire system. In addition to security, Wind River Platform for Safety Critical ARINC 653 is certifiable to DO-178B Level A for safety certification.

"Developing technology capable of reaching EAL 7 certification is a significant step forward in secure device software operating system technology," said Dave Fraser, chief marketing officer for Wind River. "To work with Smiths Aerospace and be used by Boeing on the C-130 AMP program is an honor, and Wind River is proud to be developing safe and secure technologies that will help strengthen our country's security infrastructure."

• Highly optimized device software enables customized, localized programming feeds and targeted content through IntelliStar

ALAMEDA, Calif.--March 29, 2004--Wind River Systems, Inc (NASDAQ: WIND), the global leader in device software optimization (DSO), today announced that The Weather Channel engaged Wind River for product development and realization of their new IntelliStar system--a next-generation, geography-specific TV programming system and device. By relying on Wind River to develop the Thunderstorm PCI card, the brains of the IntelliStar, The Weather Channel leveraged Wind River's device software expertise and technology portfolio to architect, develop, deliver and field test the IntelliStar. IntelliStar will be used by TV program distributors nationally, including Cox Communications, Comcast Communications, DirecTV, Charter Cable, and National Cable Television Cooperative.

IntelliStar is the basis of the next generation WEATHER STAR®, The Weather Channel's unique broadcast localization system. The localization of broadcasts allows The Weather Channel to target relevant weather, programming and advertising content to its viewers. Some 2,000 IntelliStar-based systems will be deployed to cable headends across the country reaching an estimated 50 million viewers by the fall of 2004.

"The IntelliStar provides our customers with immediate enhancements and opens the way for future programming advances and support for new revenue services," said Brian Shield, executive vice president and Chief Information Officer at The Weather Channel. "Wind River provided us with he device software and services expertise that were required to reach a new level of programming advances that include robust content and sophisticated localization capabilities. By using Wind River's services, we were able to get IntelliStar to market on time and with a reduced bill of materials (BOM)."

The IntelliStar provides sophisticated capabilities in television broadcasting with support for localized and targeted content. Technically, the IntelliStar device can support SDI or analog video input, render real-time graphics and play stored content (e.g. data, movie files, ads, etc.) providing a richer, more contextually relevant experience for the viewer. All of the content generated or played through the IntelliStar can be output on the analog and digital-tier simultaneously allowing the IntelliStar to easily interoperate within a digital cable head-end.

"By leveraging Wind River's expertise in software optimization, The Weather Channel was able to deliver this next generation product more efficiently and set the stage for future revenue opportunities," said Brad Murdoch, vice president of Alliances for Wind River.
