This Amendment No. 4 to the Schedule TO is being filed on behalf of rStar and Gilat. All of the information set forth in the Offer to Exchange/Prospectus and related Letter of Transmittal, each as may be amended from time to time, and any prospectus supplement or other supplement thereto related to the Exchange Offer and filed with the SEC by Gilat and/or rStar, is hereby incorporated by reference in answer to Items 1 through 11 of the Schedule TO, and is supplemented by the information specifically provided herein. rStar and Gilat commenced the Exchange Offer on March 28, 2002. However, in accordance with applicable SEC rules and regulations, rStar and Gilat temporarily suspended the Exchange Offer on April 1, 2002 until such time as rStar stockholders were provided with an updated offer to exchange/prospectus containing Gilat's audited financial statements for the fiscal year ended December 31, 2001. These financial statements are contained in the updated Offer to Exchange/Prospectus dated June 25, 2002, which is filed as Exhibit (a)(4) hereto. Accordingly, by means of mailing to rStar stockholders the updated Offer to Exchange/Prospectus dated June 25, 2002, and all related documents, including the Letter of Transmittal, which is filed as Exhibit (a)(1)(A) hereto, rStar and Gilat have resumed the Exchange Offer and have extended the expiration date for the Exchange Offer to 12:00 Midnight, New York City time, Thursday, July 25, 2002. rStar stockholders are advised that the Offer to Exchange/Prospectus dated June 25, 2002 contains updated information concerning rStar and Gilat and should be referred to instead of the Offer to Exchange/Prospectus dated March 28, 2002.
