FARNBOROUGH AIR SHOW, LONDON, July 23, 2002 - Wind River Systems, Inc. (Nasdaq: WIND), a leading provider of software and services for connected devices, today awarded the European Space Agency (ESA) its "Cool Customer Design" award for the PROBA (Project for On-Board Autonomy) micro-satellite system the first ESA spacecraft with fully autonomous capabilities. The PROBA satellite operates virtually unaided by ESA staff on the ground with the help of Wind River's market-leading VxWorks real-time operating system (RTOS). PROBA is currently in orbit 600 kilometers above the Earth's surface, testing the validity of self-functioning space technologies and performing several scientific activities to monitor the health of our planet.

"We chose Wind River's VxWorks operating system for PROBA because of its robustness and proven reliability on space missions," said Dominique Baudoux, Space Business Unit Program Manager for Spacebel the subcontractor responsible for providing PROBA's flight software. "Because PROBA operates virtually unaided, we needed a trustworthy operating system capable of reliable operation while in space. PROBA is thus far a great success and we are very pleased with the software."

PROBA was launched via rocket by the Indian Space Research Organization and sent into orbit on October 22, 2001. Despite being very small in size and weight, the satellite boasts an extensive range of advanced capabilities and instrumentation. PROBA has the ability to observe the same spot on Earth from a number of different angles, and has already provided scientists with detailed environmental images through its compact high resolution imaging spectrometer (CHRIS) the main payload onboard the spacecraft. Data from the lightweight instrument are sent automatically from PROBA to ESA's ground station in Redu, Belgium, allowing scientists to develop tools for environmental monitoring, forest cataloging, crop forecasting and marine science.

Wind River's VxWorks RTOS controls all on-board functions of the PROBA satellite. The unique capabilities of the VxWorks RTOS also help enable PROBA to upload new versions of software as it orbits the earth. This functionality is based on Wind River's robust 'incremental linking' technology. The scalability of the VxWorks RTOS also proved extremely important, as the operating system memory footprint was reduced to a minimum while reliably controlling all on-board instruments, tests and communications. The VxWorks kernel accounts for less than ten percent of the total lines of code on-board PROBA.

"Wind River has a strong history in space exploration including major projects with NASA and other agencies like the ESA, which speaks to the proven reliability of our technology," said Steve Blackman, director of marketing for Wind River's aerospace and defense business unit. "Developers of spacecraft have been able to leverage Wind River's integrated, commercial-off-the-shelf software solutions and development tools to get to market much faster than by developing their own solutions or turning to other COTS vendors."

During its projected two-year lifetime, PROBA will be performing a series of scientific and housekeeping activities that can be planned, controlled and monitored by both the ground team and the satellite's on-board computer. Functions that will be tested for autonomy possibilities include scheduling and planning of scientific experiments, data collection, communications between PROBA, scientific users, and the ground team, management of routine satellite functions, and failure detection. Most satellites currently require interaction between the ground and the spacecraft to carry out similar activities.

Wind River today announced that the company continues to drive technology to new heights by providing a network stack that supports the next generation Internet Protocol, known as IPv6. The first product generally available is WindNet IPv6.

• Japan, the Asia Pacific region, Europe and the rest of the world suffer from a shortage of IP addresses and are looking to companies such as Wind River to provide them IPv6 technology.
• Global customers who want to develop next generation communications products ranging from small/home office appliances, consumer electronics and network infrastructure equipment can turn to Wind River.
• As an extension to its market-leading embedded operating system, VxWorks, Wind River's IPv6 product offering will help the new protocol proliferate broadly in all manner of connected devices.
• Current "early adopter" customers include Siemens and Hughes Network Systems.

ALAMEDA, CA and TOKYO, JAPAN - July 17, 2002 - Wind River Systems, Inc. Nasdaq:WIND), a leading provider of software and services for connected devices, today announced the release of WindNet IPv6 (Internet Protocol version 6). Developed in concert with one of Wind River's lead customers, Siemens (NYSE: SI), WindNet IPv6 provides the protocol and integrated networking support required to efficiently leverage IPv6 technology - the world's next-generation IP protocol that will serve as the foundation for all Internet traffic. Join Wind River's Webcast on August 7, 2002 to learn more about IPv6. Pre-registration is available at http://seminar2.techonline.com/~wrsamerica22/aug0702/.

"Currently, IP version 4 (IPv4) supports up to four billion IP addresses, yet the number of connected devices ranging from desktop PCs and cell phones to wireless automotive applications continue to increase at a rapid pace. The IPv4 address space will soon be exhausted, making it imperative that companies provide technology to support this growth," said Dave Fraser, group vice president of products at Wind River. "By providing our global customers with IPv6 products, Wind River will help to enable the future growth of a connected world and accelerate Internet communications."

"Hughes Network Systems has been using Wind River's software in selected products for more than 12 years", said John Kenyon, senior vice president, software engineering at Hughes Network Systems." Their VxWorks operating system, IPv4 stack, and home gateway routing software have helped us to achieve improved time-to-market and higher product quality, and we now look forward to implementing IPv6 in the future."

IPv6 is expected to replace the current Internet Protocol version IPv4 used throughout the Internet. IPv6 is designed to enable future growth of the Internet by enhancing the current IP protocol standard. It includes the ability to provide a virtually unlimited amount of user addresses for networks and systems connected to the Internet, and improved data security features. Because there are a finite number of IPv4 user addresses, which are being quickly exhausted by the rapid deployment of new usages of the Internet, IPv6 is quickly gaining support in Japan, the Asia Pacific region and Europe where IP addresses are in short supply.

The auto-configuration mechanism built into IPv6 provides another key advantage over IPv4, enabling customers to connect any device to the Internet without having to configure complicated network parameters. The new protocol also enables Internet traffic requiring varying qualities of service to be supported, facilitating a rich mix of voice, video, and data communications.

WindNet IPv6 is a full-featured implementation of the internationally accepted IPv6 networking standards. Designed with special attention to performance, scalability, and hardware portability, the new product leverages Wind River's experience as the world's leading provider of embedded technology. WindNet IPv6 is also fully integrated with Wind River's market-leading VxWorks real-time operating system, Tornado development tools, device management products and related networking protocols - giving developers all necessary components to build and manage IPv6-enabled products. Finally, the product is prepared to support the IPsec security protocol that provides authentication and encryption for Internet traffic. Customers can use Wind River's IPsec implementation as the foundation for creating secure virtual private networks (VPNs) and secure end-to-end communication.

In addition, WindNet IPv6 can be used in 3G wireless applications. Wireless networking vendors need IPv6 if their products are to effectively communicate with one another. With the proliferation of globally routable IP-aware devices, such as cell phones, video-game consoles and PDAs - combined with the increasing demand for wireless Web access - migration to IPv6 is becoming a necessity.

"Siemens requires IPv6 technology for the development of next generation wireless telephony and infrastructure equipment (3G). Through our long-standing relationship with Wind River, Siemens looked to Wind River to develop and integrate an IPv6 protocol stack into our various products," said Director of R&D Klaus Hjorth of Siemens Mobile Networks. "Through Wind River's dedication to the future of IPv6, Siemens will be able to offer its customers next generation Internet technology."

Availability
WindNet IPv6 is currently available for "early adopter" customers and will be available generally by September 2002. Additional WindNet IPv6 products to include a stack tuned for routing applications, routing protocols, remote access, security, management and voice over IP.
