At the same time, rStar mailed to its stockholders a Notice of Annual Meeting and Proxy Statement, relating to its Annual Meeting to be held on April 30, 2002. rStar and Gilat also announced that, in accordance with SEC rules and regulations, the exchange offer, pursuant to which rStar shareholders are offered the right to exchange shares of rStar common stock for Gilat Ordinary Shares and cash, has been temporarily suspended until such time as an amendment to the Offer to Exchange containing Gilat's audited financial statements for the fiscal year ended 2001 is mailed to rStar stockholders. Applicable SEC rules and regulations require that, during the entire time that the exchange offer for shares of rStar common stock is open, the audited financial statements of Gilat included in the Offer to Exchange must be no more than 15 months old. This means that as of today, an amendment to the Offer to Exchange that includes Gilat's audited financial statements for the year ended 2001 must be filed with the U.S. Securities Exchange Commission and mailed to rStar stockholders. While there can be no assurance, Gilat and rStar expect that the required amendment including those financial statements will be filed in the next few weeks. rStar shareholders are encouraged to review the terms of the exchange offer contained in the Offer to Exchange. However, during the period beginning April 1, 2002 and until an amendment including Gilat's audited 2001 financial statements is mailed to rStar stockholders or the exchange offer is otherwise terminated, the exchange offer will be temporarily suspended, rStar stockholders are asked not to tender their shares and any tenders of shares of rStar common stock WILL NOT BE ACCEPTED by the exchange agent. Stockholders who submit to the exchange agent the letter of transmittal or any share certificates before the required amendment to the Offer to Exchange is filed will have such materials returned to them. The amendment containing Gilat's audited 2001 financial statements will be mailed to all rStar stockholders to whom the Offer to Exchange was mailed, at which time rStar and Gilat will also issue a joint press release announcing the re-commencement of the exchange offer and the new expiration date. The expiration date of the exchange offer will be extended to a date 20 business days after the date that the amendment containing Gilat's audited 2001 financial statements is first mailed to rStar stockholders. Tenders may be withdrawn at any time before the expiration date of the exchange offer, as extended for the 20 business day period, as described above. Notwithstanding the temporary suspension of the exchange offer, rStar intends to hold its Annual Meeting on April 30, 2002. At that meeting rStar stockholders are being asked to, among other things, approve the proposed acquisition by rStar of StarBand Latin America from Gilat. Accordingly, rStar stockholders are asked to review the Notice of Meeting a Proxy Statement which has been delivered to them and return the enclosed proxy card as soon as practicable.
