Filed by General Motors Corporation Subject Company - General Motors Corporation and Hughes Electronics Corporation and EchoStar Communications Corporation Pursuant to Rule 425 under the Securities Act of 1933 and Deemed Filed Pursuant to Rule 14a-12 under the Securities Exchange Act of 1934 Commission File No.: 333-84472 The following was distributed to Hughes and PanAmSat employees on September 26, 2002: September 26, 2002 TO: Hughes and PanAmSat Employees I know you have read with extreme interest, as I have, all the news articles regarding our merger that have appeared in the past few days. I'd like to clarify some of the details for you. First, you should know that Hughes and GM representatives met with the Justice Department Antitrust Division Tuesday, and we were assured that the staff recommendations regarding approval of the merger have not been made. We are still engaged in discussions with both the Justice Department and Federal Communications Commission, and the review process is ongoing. Also, there was speculation in yesterday's Los Angeles Times that a management-led buyout of DIRECTV was under consideration, and that DIRECTV President Roxanne Austin had discussed this possibility with senior leaders at DIRECTV. Roxanne has denied any such discussions, and I can personally assure you that no such alternatives are being considered. I should also point out that any decisions on the future of Hughes and its operating companies always will be made by General Motors and Hughes corporate leaders, not by individual operating companies. I would also like to remind all employees that any comments or speculation regarding confidential or sensitive business information to the press or other third parties are not only inappropriate, they are very unproductive, and violate company policy. Let me reiterate that the leaders of Hughes and GM are thoroughly committed to completing our proposed merger with EchoStar. I strongly believe that this merger is the best outcome for our company, our customers, and our shareholders. Our management focus is on completing the merger while running our businesses as efficiently and competitively as possible, so that we enter the merger as a stronger and healthier company and give a running start to the newly merged enterprise. We have delivered a letter to the Los Angeles Times communicating these points, and a copy of that letter is available on our website. Thanks, as always, for your patience regarding the merger and your persistence in striving for excellence in your business.
