First Amendment to Amended and Restated Rights Agreement



 Exhibit 4.2 
 FIRST AMENDMENT TO AMENDED AND RESTATED RIGHTS AGREEMENT 
 This FIRST AMENDMENT, dated as of
June 4, 2009 (this “Amendment”), to Amended and Restated Rights Agreement, dated as of September 29, 2006 (the “Agreement”), between Wind River Systems, Inc., a Delaware corporation (the
“Company”), and American Stock Transfer and Trust Company, as rights agent (the “Rights Agent”). 
 RECITALS 
 WHEREAS, Intel Corporation, a Delaware corporation (“Parent”), APC II Acquisition
Corporation, a Delaware corporation and a wholly-owned subsidiary of Parent (“Purchaser”) and the Company contemplate entering into an Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which it is
proposed that Purchaser make a cash tender offer to acquire all of the issued and outstanding shares of common stock of the Company (as it may be amended from time to time, the “Offer”), to be followed by a merger of Purchaser with
and into the Company, with the Company surviving the merger as a wholly-owned subsidiary of Parent, upon the terms and subject to the conditions of the Merger Agreement. 
 WHEREAS, pursuant to Section 27 of the Agreement, prior to the Distribution Date, the Company and the Rights Agent shall, if the Company so directs, from time to time supplement and amend any provision of
the Agreement without the approval of any holders of the Rights. 
 WHEREAS, no Distribution Date has occurred, and no person has been
an Acquiring Person. 
 WHEREAS, concurrently with the execution and delivery of the Merger Agreement, and as a condition and
inducement to Parent’s willingness to enter into the Merger Agreement, Parent, Purchaser and certain stockholders of the Company (the “Stockholders”) are entering into a Tender and Support Agreement, dated as of the date hereof
(the “Stockholder Agreement”), providing that, among other things, the Stockholders shall (i) tender their Company Shares (as such term is defined in the Merger Agreement) into the Offer, and (ii) vote their Company Shares
in favor of the Merger, if applicable, in each case subject to the conditions set forth therein. 
 WHEREAS, the Board of Directors of
the Company has resolved that an amendment to the Agreement as set forth herein is necessary and desirable in connection with the foregoing and to exempt the Merger Agreement, the Offer, the Stockholder Agreement and the other transactions
specifically contemplated thereby from the application of the Amendment, and has approved this Amendment. 
 WHEREAS, the Company
intends to modify the terms of the Agreement in certain respects as set forth herein, and in connection therewith, is entering into this Amendment and directing the Rights Agent to enter into this Amendment.
