ITEM 5. OTHER EVENTS.

      On October 9, 2001, the Registrant announced that its wholly-owned
subsidiary, Liberty UPC Bonds, Inc. (the "Offeror"), had commenced an offer to
purchase for cash, upon the terms and subject to the conditions set forth in the
Offer to Purchase, dated October 9, 2001, and the accompanying letter of
transmittal (collectively, the "Offer"), for the principal amounts specified in
the Offer to Purchase of, and at prices designated by the holders within the
ranges specified in the Offer to Purchase for, the notes issued by United
Pan-Europe Communications N.V., a corporation organized under the laws of The
Netherlands ("UPC"), specified in the Offer to Purchase.

      The purchase price for each series of notes subject to the Offer will be
determined by the "Modified Dutch Auction" procedure, whereby the Offeror will
select the single lowest price specified by tendering holders within a price
range set forth in the Offer to Purchase that will enable the Offeror to
purchase the principal specified in the Offer to Purchase for that series. The
Offer is conditioned on the Offeror receiving valid, unwithdrawn tenders of
notes representing at least 30% of all series of notes subject to the Offer and
on the other conditions contained in the Offer to Purchase being satisfied, or
waived, on the expiration date. The Offer is scheduled to expire at 11:59 p.m.,
New York City time, on November 6, 2001, unless extended.

      This Form 8-K is qualified in its entirety by (i) the text of the Offer to
Purchase and accompanying letter of transmittal; (ii) a press release, dated
