ITEM 5.  OTHER EVENTS.

         On December 31, 2001, Liberty Media Corporation ("Liberty") and its
subsidiaries, Liberty Media International, Inc. ("LMI") and Liberty Global, Inc.
("Liberty Global") entered into an Amended and Restated Agreement and Plan of
Restructuring and  Merger (the "Merger Agreement") with New UnitedGlobalCom,
Inc. ("New United"), UnitedGlobalCom, Inc. ("United"), a newly formed merger
subsidiary of New United ("Merger Sub"), and certain major stockholders of
United (the "Founders"). A copy of the Merger Agreement is attached as Exhibit
7(c)(1) to this Form 8-K. The Merger Agreement amends and restates in its
entirety the Agreement and Plan of Restructuring and Merger, dated December 3,
2001, among Liberty, LMI, Liberty Global, New United, United, Merger Sub and
the Founders, a copy of which agreement was filed as an exhibit to Liberty's
Current Report on Form 8-K dated December 5, 2001(the "Original Merger
Agreement"). The Merger Agreement amended the transactions contemplated by the
Original Merger Agreement primarily in order to provide for the conversion of
United's Series B preferred stock, Series C preferred stock and Series D
preferred stock into shares of New United Class A common stock in the merger
rather than shares of new series of United preferred stock, as had been
contemplated by the Original Merger Agreement.
