("HCI"), Hughes Communications Galaxy, Inc. ("HCG") and Hughes Communications Satellite Services, Inc. ("HCSS", and, collectively with GM, HCI and HCG, the "Reporting Persons") with respect to the shares of common stock, par value $.01 per share ("Common Stock"), of PanAmSat Corporation (the "Company"). The responses to Item 2 (Identity and Background), Item 4 (Purpose of Transaction), Item 5 (Interest in Securities of the Issuer), Item 6 (Contracts, Arrangements, Understandings or Relationships with respect to Securities of the Issuer) and Item 7 (Material to be filed as Exhibits) are hereby amended as follows: Item 2: Identity and Background. ------------------------ This statement is being filed jointly by GM, HCI, HCG and HCSS. Each of HCI, HCG and HCSS is a California corporation. The address of each of HCI's, HCG's and HCSS' principal office is 200 N. Sepulveda Blvd., El Segundo, California 90245. The names, business addresses, principal businesses and citizenship of each of the directors and executive officers of each of HCI, HCG and HCSS are set forth on Schedule I hereto and incorporated by reference herein. The principal businesses of HCI, HCG and HCSS are to act as holding companies. HCG and HCSS are wholly-owned subsidiaries of HCI. HCI is a wholly-owned subsidiary of Hughes Telecommunications & Space Company ("HTS"); and HTS is a wholly-owned subsidiary of Hughes Electronics Corporation ("Hughes"). Hughes is a wholly-owned subsidiary of GM. During the last five years, none of the Reporting Persons nor, to the best of their knowledge, any of the executive officers or directors of any of the Reporting Persons, has been (i) convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and, as a result of such proceeding, was or is subject to a judgment, decree or final order enjoining such future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws. Item 4. Purpose of Transaction. ---------------------- GM, Hughes and The News Corporation Limited have entered into a Stock Purchase Agreement, dated as of April 9, 2003 (the "Stock Purchase Agreement"). In connection with the Stock Purchase Agreement, Hughes and GM have entered into a Separation Agreement, dated as of April 9, 2003 (the "Separation Agreement"), which provides for the split-off of Hughes from GM. Simultaneously with the closing under the Stock Purchase Agreement and if the conditions contained in the Stock Purchase Agreement are satisfied or waived (these conditions include, among other things, obtaining U.S. antitrust and Federal Communications Commission approvals, obtaining appropriate approvals of GM's stockholders and obtaining a favorable ruling as to certain tax matters from the Internal Revenue Service), Hughes will be split off from GM. After the split-off, Hughes will no 6 longer be a subsidiary of GM and, as a result, GM will no longer be deemed to be the beneficial owner of any shares of Common Stock of the Company. As previously disclosed on Schedule 13D, (i) on May 16, 1997, HCI received 106,622,807 shares of Common Stock in exchange for HCI and certain of its subsidiaries contributing the assets and liabilities comprising substantially all of HCI's satellite services business to the Company and (ii) on April 30, 1998 and May 1, 1998, HCI purchased an aggregate of 14,189,368 additional shares of Common Stock. On October 30, 2001, HCI transferred 17,729,545 shares of Common Stock to HCSS, 88,605,390 shares of Common Stock to HCG and retained 14,477,240 shares of Common Stock. Except as discussed above, none of the Reporting Persons has any present plan or proposal which relates to, or could result in, any of the events referred to in paragraphs (a) through (j), inclusive, of Item 4 of Schedule 13D. Item 5: Interest in Securities of the Issuer. ------------------------------------ (a) The responses of the Reporting Persons to Rows (11) through (13) of the cover pages of this Amendment No. 6 are incorporated herein by reference. As of March 31, 2003, the Reporting Persons beneficially owned the number of shares of Common Stock listed below, representing approximately the percentage of the outstanding shares of Common Stock set forth opposite such number (based on 150,028,729 shares of Common Stock outstanding as of March 31, 2003). ---------------------------------------------- -------------------------------------------- ---------------------------------------- Person Number of Shares Percent of Class ------ ---------------- ---------------- ---------------------------------------------- -------------------------------------------- ---------------------------------------- General Motors Corporation 120,812,175 80.5% ---------------------------------------------- -------------------------------------------- ---------------------------------------- Hughes Communications, Inc. 14,477,240 9.6% ---------------------------------------------- -------------------------------------------- ---------------------------------------- Hughes Communications Galaxy, Inc. 88,605,390 59.1% ---------------------------------------------- -------------------------------------------- ---------------------------------------- Hughes Communications 17,729,545 11.8% Satellite Services, Inc. ---------------------------------------------- -------------------------------------------- ---------------------------------------- (b) The responses of the Reporting Persons to (i) Rows (7) through (10) of the cover pages of this Amendment No. 6 and (ii) Item 5(a) hereof are incorporated herein by reference. GM, acting through Hughes and HTS, indirectly has sole power to vote or direct the vote, and to dispose or to direct the disposition of the shares of Common Stock. As a result, GM may be deemed to beneficially own the shares of Common Stock directly owned by HCI, HCG and HCSS. 7 (c) Not Applicable. (d) Except as stated in this Item 5, to the best of the knowledge of the Reporting Persons, no other person has the right to receive dividends from, or the proceeds from the sale of, the shares of Common Stock owned by the Reporting Persons.
