Item 1.  Changes in Control of the Registrant.
- ----------------------------------------------

         On May 16, 1997, Hughes Communications, Inc. ("HCI") and PanAmSat
International Systems, Inc. (formerly known as PanAmSat Corporation, "Old
PanAmSat") combined their satellite operations pursuant to an Agreement and Plan
of Reorganization, dated as of September 20, 1996, as amended as of April 4,
1997 (the "Reorganization Agreement"), between HCI and certain of its
subsidiaries and Old PanAmSat (the "Merger"). The Merger was consummated through
the merger of a wholly owned subsidiary of a newly formed holding company (such
holding company, "New PanAmSat"), with and into Old PanAmSat and a contribution
of the satellite services business of HCI to New PanAmSat, with the result that
Old PanAmSat became a wholly owned subsidiary of New PanAmSat and New PanAmSat
became the owner and operator of the HCI satellite services business. Following
the Merger, Old PanAmSat was renamed PanAmSat International Systems, Inc. and
New PanAmSat was renamed PanAmSat Corporation. Upon consummation of the Merger,
each direct or indirect holder of each outstanding share of stock, par value
$0.01 per share, of Old PanAmSat received, at such holder's election (the
"Elections"), (i) one share of common stock, par value $0.01 per share of New
PanAmSat ("New PanAmSat Common Stock"), (ii) $15 in cash plus one-half share of
New PanAmSat Common Stock or (iii) $30 in cash, subject to proration. As a
result of the Elections and in accordance with the Reorganization Agreement and
the Stock Contribution and Exchange Agreement dated as of September 20, 1996
(the "Univisa Contribution Agreement") among Grupo Televisa, S.A. a Mexican
corporation ("Televisa"), Satellite Company, LLC, a Nevada limited liability
company ("S Company"), New PanAmSat and HCI, Elections to receive $30 in cash
were prorated, resulting in each such Election receiving approximately $16.38 in
cash and 0.45 shares of New PanAmSat Common Stock in exchange for each share of
common stock of Old PanAmSat.

         In exchange for the contribution of the existing satellite services
business of HCI and certain of its subsidiaries, HCI received 106,622,807 shares
of New PanAmSat Common Stock, an amount equal to 71.5% of New PanAmSat's issued
and outstanding Common Stock. Prior to the Merger, Old PanAmSat had been
controlled by the former holders of Old PanAmSat's Class A Common Stock, subject
to certain veto rights of the former holder of Old PanAmSat's Class B Common
Stock. For a discussion of arrangements and understandings among members of the
former controlling stockholders of Old PanAmSat and the new controlling
stockholder of New PanAmSat with respect to the election of directors and other
matters, reference is made to the Amended and Restated Stockholder Agreement,
dated as of May 16, 1997, by and among Magellan International, Inc., HCI, S
Company and the former holders of Class A Common Stock of Old PanAmSat, which is
filed herewith and is incorporated herein by reference.

         Pursuant to an Assurance Agreement dated September 20, 1996, among
Hughes Electronics, a Delaware Corporation ("HE"), Old PanAmSat, New PanAmSat
and S Company, HE agreed to lend up to $1.725 billion to New PanAmSat on the
closing date of the Merger. HE borrowed from General Motors the funds necessary
to provide the new financing and such funds were loaned to New PanAmSat by an
affiliate of HE, Hughes Network Systems Inc., pursuant to a loan agreement (the
"Loan Agreement"). The Loan Agreement provides for a three year term loan
bearing interest at a rate of 2% above the London Interbank Offering Rate (which
interest rate is subject to renegotiation if New PanAmSat attains an investment
grade credit rating or Old PanAmSat ceases to be subject to restrictions (a) on
making restricted payments and (b) on pledging its assets contained in the
indentures governing Old PanAmSat's existing indebtedness and the certificate of
designation for Old PanAmSat's Preferred Stock). New PanAmSat is required to pay
seven quarterly installments of $50 million each commencing August 1, 1998, with
the balance of the loans payable on May 1, 2000. Under the Loan Agreement, New
PanAmSat is required to make certain prepayments of principal upon the
occurrence of certain events, including (i) the issuance of equity, (ii) the
issuance or incurrence of debt evidenced as a new borrowing in excess of
$5,000,000, (iii) the sale of assets with a fair market value in excess of
$10,000,000 of New PanAmSat or its material subsidiaries, if the proceeds
therefrom are not reinvested in New PanAmSat or its material subsidiaries within
180 days and (iv) the receipt of insurance proceeds in excess of $5,000,000, if
such proceeds are not reinvested in New PanAmSat or its material subsidiaries.
The Loan Agreement contains covenants that prohibit or limit, among other
things, pledges of


                                  Page 2 of 7



New PanAmSat's assets and the incurrence of certain indebtedness and requires
that New PanAmSat and its subsidiaries maintain a certain consolidated net
worth. New PanAmSat's obligations under the Loan Agreement are guaranteed by
Hughes Communications Services, Inc., Hughes Communications Japan, Inc., and
Hughes Communications Carrier Services, Inc., subsidiaries of New PanAmSat. All
obligations of New PanAmSat and its subsidiaries under the Loan Agreement are
subject to restrictions imposed on them under the indentures governing Old
PanAmSat's existing indebtedness and the certificate of designation for Old
PanAmSat's preferred stock; additionally, neither New PanAmSat nor any of its
subsidiaries are prohibited under the Loan Agreement from taking any action
thereunder which it is permitted to take under such indentures or certificate of
designation.

         Immediately prior to the Merger, in a separate but related transaction
(the "Univisa Contribution") and pursuant to the Univisa Contribution Agreement,
New PanAmSat acquired from S Company all of the capital stock of PanAmSat
International Holdings, Inc. (formerly known as Univisa, Inc.), a Delaware
corporation, which is the indirect holder of all of the outstanding Old PanAmSat
Class B Common Stock. As consideration for the Univisa Contribution, S Company
received for its shares of Old PanAmSat Class B Common Stock, $611,501,153 in
cash and 6,239,594 shares of New PanAmSat Common Stock, following the Share
Repurchase and the DTH Sale (as defined below). Concurrently with the Merger and
immediately following the Univisa Contribution, 7.5 million shares of New
PanAmSat Common Stock received by S Company in connection with the Univisa
Contribution were repurchased by New PanAmSat for $225 million (the "Share
Repurchase"). Following the Share Repurchase, DTH, LLC, a Delaware limited
liability company and designee of Televisa, purchased for $225 million all of
Old PanAmSat's rights to purchase from Televisa equity interests in certain
joint ventures to be formed to offer direct-to-home services in Latin America
and the Iberian Peninsula, pursuant to the DTH Option Purchase Agreement dated
as of September 20, 1996 between Old PanAmSat, Televisa and S Company (the "DTH
Sale").

         The total amount of funds paid by New PanAmSat as consideration in the
Merger and the Univisa Contribution Agreement was approximately $1.725 billion,
including (i) approximately $1.5 billion paid to the former holders of Old
PanAmSat's Class A Common Stock, Old PanAmSat's Ordinary Common Stock and
options to acquire Old PanAmSat's Ordinary Common Stock and the former
beneficial holder of Old PanAmSat's Class B Common Stock, and (ii) $225 million,
to fund the Share Repurchase.


Item 2.  Acquisition or Disposition of Assets.
- ----------------------------------------------

         As disclosed above, New PanAmSat acquired Old PanAmSat as a result of
the Merger. See Item 1.
