                                VOTING AGREEMENT

         This Voting Agreement (this "AGREEMENT") dated as of January 30, 2002,
is entered into among New UnitedGlobalCom, Inc., a Delaware corporation that

Stock to be contributed to United in exchange for an equal number of shares of
the Class B Common Stock, par value $0.01 per share, of United ("CLASS B COMMON
STOCK"). It is a condition to the consummation of the transactions contemplated
by the Merger Agreement, including without limitation the Merger, that United
and the Founders each execute and deliver this Agreement.

the manner of the election of the Board of Directors of United that will become

                  members of the Board or, if greater, such number of members of
                  the Board (rounded up to the next whole number) equal to

         (b)      Each Founder and its Permitted Transferees shall vote or cause

                  right to vote or direct the voting) for the election to the
                  Board of those persons nominated in accordance with this
                  Section 2 and will not seek the removal of any director (other
                  than a Founder Director) except for cause; provided that, if
                  the Liberty Parties request that the Controlling Principals

                  Controlling Principals will vote or cause to be voted all

                  constituency provided for in Section 2(a) and to give effect

                  created by the resignation, removal, incapacity or death of

events occurs, the "TERMINATION DATE").

         Section 4. APPLICABLE LAW, JURISDICTION. This Agreement shall be
governed by Colorado law without regard to conflicts of law rules. The parties
hereby irrevocably submit to the exclusive jurisdiction of any Colorado State or
United States Federal court sitting in Colorado over any action or proceeding
arising out of or relating to this Agreement or any agreement contemplated
hereby, and the undersigned hereby irrevocably agree that all claims in respect
of such action or proceeding shall be heard and determined in such State or
Federal court. The undersigned further waive any objection to venue in such
State and any objection to any action or proceeding in such State on the basis
of a non-convenient forum. Each party hereby IRREVOCABLY WAIVES ANY RIGHT TO A
TRIAL BY JURY in any proceeding brought with respect to this Agreement or the
transactions contemplated hereby.

         Section 5. REMEDIES. Each of the parties acknowledges and agrees that
in the event of any breach of this Agreement, the nonbreaching party would be
irreparably harmed and could not be made whole by monetary damages. Accordingly,
the parties to this Agreement, in addition to any other remedy to which they may
be entitled hereunder or at law or in equity, shall be entitled to compel
specific performance of this Agreement.

         Section 6. HEADINGS. The headings in this Agreement are for convenience
only and are not to be considered in interpreting this Agreement.

         Section 7. COUNTERPART EXECUTION. This Agreement may be executed in any
number of counterparts, each of which shall be deemed an original but all of
which will constitute a single agreement.

         Section 8. PARTIES IN INTEREST. Nothing in this Agreement, express or
implied, is intended to confer upon any Person other than the parties hereto and
their Permitted Transferees, and their permitted successors and assigns any
benefits, rights or remedies, except that Liberty is an intended beneficiary of
this Agreement. Neither this Agreement nor the rights or obligations of any
party may be assigned or delegated (other than to a Permitted Transferee in
accordance with the terms of the Stockholders Agreement) by operation of law or
otherwise without the prior written consent of the Controlling Principals and
United.

         Section 9. SEVERABILITY. The invalidity or unenforceability of any
provision of this Agreement in any application shall not affect the validity or
enforceability of such provision in any other application or the validity or
enforceability of any other provision.

         Section 10. INTERPRETATION. As used herein, except as otherwise
indicated herein or as the context may otherwise require, the words "include,"
"includes" and "including" are deemed to


                                       4

<Page>

be followed by "without limitation" whether or not they are in fact followed by
such words or words of like import; the words "hereof," "herein," "hereunder"
and comparable terms refer to the entirety of this Agreement and not to any
particular section hereof; any pronoun shall include the corresponding
masculine, feminine and neuter forms; the singular includes the plural and vice
versa; references to any agreement or other document are to such agreement or
document as amended and supplemented from time to time; references to "Section"
or another subdivision are to a section or subdivision hereof; and all
references to "the date hereof," "the date of this Agreement" or similar terms
(but excluding references to the date of execution hereof) refer to the date
first above written, notwithstanding that the parties may have executed this
Agreement on a later date.

         Section 11. RULES OF CONSTRUCTION. The parties hereto agree that they
have been represented by counsel during the negotiation, preparation and
execution of this Agreement and, therefore, waive the application of any law,
regulation, holding or rule of construction providing that ambiguities in an
agreement or other document will be construed against the party drafting such
agreement or document.

         Section 12. WAIVERS AND AMENDMENTS. No waiver of any provision of this
Agreement shall be deemed a further or continuing waiver of that provision or a
waiver of any other provision of this Agreement. This Agreement may not be
amended nor may any provision hereof be waived except in a writing signed by all
parties and Liberty or its successor. United may waive any provision of this
Agreement that imposes obligations on or restricts the rights of or actions by
the Founders and their Permitted Transferees only with the prior approval of a
majority of the Board.
