Subject: Intel to Acquire Wind River Systems, Inc.

INTEL CONFIDENTIAL, NOT FOR EXTERNAL DISTRIBUTION

***DO NOT DISTRIBUTE TO YOUR STAFF UNTIL AFTER THE NEWS***

We are pleased to announce that Intel has entered into a definitive agreement to acquire Wind River Systems, Inc., headquartered in Alameda, California. Wind River is the leading software vendor for embedded systems and mobile devices and posted revenue of $360M in FY 2009.

Intel will, subject to prior regulatory and shareholder approval, acquire all of Wind River’s outstanding common stock for $11.50 per share, valued at $884 million ($775 inclusive of options and net of cash)

Wind River, founded in 1981, designs and develops operating systems, middleware, and software design tools for a broad spectrum of embedded and mobile devices, making them an excellent fit with Intel’s growth areas. Wind River’s products and technologies can be found in over 500 million devices worldwide and more than 40,000 software developers design with its products.

At the close of the deal, Wind River will operate as a wholly owned subsidiary of Intel, reporting to SSG. The goal is to allow Wind River to operate business-as-usual and minimize disruptions. They will continue to operate out of their current facilities. Additionally, there will be an Intel Program Manager in SSG that will manage the relationship between Intel and Wind River.

Until the program office is fully formed, the transition team contacts include:

•       Renee James •       Mike Scoggins •       Dave Law •       Chi Miller Business Owner HR Legal Finance

If you have questions, please direct them to the transition team.
