ITEM 3.  SOURCE AND AMOUNT OF FUNDS AND OTHER CONSIDERATION

         On September 30, 1999, Liberty purchased 4,929,668 shares of the
Issuer's Class B Common Stock, par value $.01 per share (the "United Class B
Common Stock"), in a privately negotiated transaction, from Apollo Cable
Partners, L.P., then a major stockholder of United, and Lawrence F. DeGeorge and
Lawrence J. DeGeorge, then members of United's board of directors, for a
purchase price of $100 per share. Each share of United Class B Common Stock is
convertible into one share of United Class A Common Stock at the election of the
holder without consideration. On November 30, 1999, the Issuer effected a
2-for-1 stock split, as a result of which Liberty received an additional
4,929,668 shares of United Class B Common Stock. Liberty's shares of United
Class B Common Stock are registered in the name of Liberty Global, Inc., a
subsidiary of Liberty ("Liberty Global").

         On June 26, 2000, Liberty purchased 345,000 shares of United Class A
Common Stock on the open market at the prices set forth on Schedule 2 to this
statement. On June 27, 2000, Liberty purchased 250,000 shares of United Class A
Common Stock on the open market at the prices set forth on Schedule 2 to this
Statement. These shares are registered in the name of Liberty Global.

         On February 23, 2001, Liberty Global purchased 568,000 shares of United
Class A Common Stock on the open market at the prices set forth on Schedule 2 to
this Statement.

         On December 3, 2001, in connection with Liberty's execution of the
Agreement and Plan of Restructuring and Merger, dated December 3,2001 (the
"Original Merger Agreement") among Liberty, Liberty Media International, Inc., a
subsidiary of Liberty ("LMI"), Liberty Global, United, New UnitedGlobalCom, Inc.
("New United"), United/New United Merger Sub, Inc., a wholly owned subsidiary of
New United ("Merger Sub"), and several major stockholders of United (the
"Founders"), a subsidiary of Liberty purchased (a) 11,976,048 shares of United
Class A Common Stock for an aggregate purchase price of $20 million (the "Note
Shares"), and (b) 14,970 shares of United Class A Common Stock for an aggregate
purchase price of $25,000 from the Issuer in privately negotiated transactions.

         Liberty obtained the funds to make the purchases described above from
its available cash.

ITEM 4.  PURPOSE OF TRANSACTION.

         The purpose of the transactions described in Item 3 was to increase
Liberty's ownership interest in United.

         On December 31, 2001, Liberty, LMI, Liberty Global, United, New United
Merger Sub and the Founders entered into an Amended and Restated Agreement and
Plan of Restructuring and Merger (the "Merger Agreement"). The Merger Agreement
amended and restated the Original Merger Agreement in all respects. Pursuant to
the terms, and subject to the conditions, of the Merger Agreement, on the
closing date the following transactions will occur: (a) Liberty will
contribute, or cause to be contributed, the Note Shares and all of the shares
of United Class B Common Stock owned by it to New United in exchange for an
equal number of


                                  Page 4 of 20

shares of the Class C Common Stock, par value $0.01 per share, of New United
("New United Class C Common Stock"), (b) the Founders will contribute, by means
of a merger of several limited liability companies wholly owned by the Founders,
all of the shares of United Class B Common Stock held by them to New United in
exchange for an equal number of shares of New United's Class B Common Stock, par
value $0.01 per share ("New United Class B Common Stock"), (c) immediately after
the contributions described in (a) and (b), Merger Sub will merge with and into
United, with United as the surviving entity in such merger (the "Merger"),
resulting in United becoming a subsidiary of New United and each share of United
Class A Common Stock and United Class B Common Stock then outstanding (other
than any such shares held by New United) being converted into one share of New
United's Class A Common Stock, par value $0.01 per share ("New United Class A
Common Stock"), (d) as a result of the Merger, each share of United's preferred
stock (other than United's Series E preferred stock) will be converted into
shares of New United Class A Common Stock, and each share of United's Series E
preferred stock (all of which shares will be owned by certain of the Founders)
will be converted into a class of common stock of United, as the surviving
entity in the Merger, and (e) immediately following the Merger, Liberty will
contribute, or cause ; to be contributed, to New United (i) exchangeable notes
issued by United Pan-Europe Communications, N.V. ("UPC"), a subsidiary of
United, and one of UPC's subsidiaries, (ii) certain debt securities issued by
UPC and (iii) $200 million in cash, in exchange for additional shares of
New United Class C Common Stock.

         The New United Class C Common Stock, all of which will be held by
Liberty and its affiliates, will be entitled to ten votes per share and will
vote together with the New United Class A and Class B Common Stock on all
matters other than the election of directors. The New United Class A Common
Stock will be entitled to one vote per share and the New United Class B Common
Stock will be entitled to ten votes per share. The New United Class C Common
Stock, voting as a separate class, will be entitled to elect four members of
New United's twelve member board of directors. The New United Class A and Class
B Common Stock, voting as a single class, will be entitled to elect the
remaining eight members of New United's board of directors. Following the
Merger, and based upon the Reporting Person's current ownership of United Class
A Common Stock, the Reporting Person will beneficially own New United Class C
Common Stock and New United Class A Common Stock representing approximately 72%
of the economic interest in New United and approximately 94% of the voting
power of New United on all matters other than the election of directors. By
virtue of its beneficial ownership of New United Class C Common Stock, Liberty
will be entitled to elect four members of New United's board of directors and
the holders of the New United Class A and Class B Common Stock will be entitled
to elect the remaining eight members of New United's board of directors. New
United will hold securities representing approximately 99.5% of the common
equity and voting interest in United (except in the election of directors) and
entitling New United to elect one-half of the directors of United. Certain
Founders, as the former holders of United's Series E preferred stock, will hold
shares of Class A common stock of United, as the surviving entity in the Merger,
representing the remaining approximately 0.5% common equity and voting interest
in United (except in the election of directors) and entitling such Founders to
elect the other one-half of United's directors. Under the certificate of
incorporation of New United, New United will not be permitted to take action
with respect to any of the following matters without the consent of a majority
of the directors elected by the holders of Class C Common Stock:

         -        the acquisition or disposition of assets or issuance of equity
                  securities in any twelve-month period exceeding 30% of New
                  United's market capitalization (excluding a sale, by merger or
                  otherwise, by New United of all or substantially all of its
                  assets or a reorganization of entities affiliated with New
                  United, provided that the holders of New United Class C Common
                  Stock are treated equally with holders of New United


                                  Page 5 of 20

                  Class B Common Stock and all holders of New United Class B
                  Common Stock are treated equally);

         -        the issuance of any shares of New United Class C Common Stock
                  (other than pursuant to certain proportional purchase rights
                  of the holders) or the issuance of any options exercisable for
                  New United Class B Common Stock in excess of three million
                  shares in the aggregate;

         -        the replacement of New United's Chief Executive Officer with
                  anyone other than Michael T. Fries, John F. Riordan, Gene W.
                  Schneider and Mark L. Schneider;

         -        any amendment to New United's certificate of incorporation or
                  bylaws that would adversely affect the rights of holders of
                  New United Class B Common Stock or New United Class C Common
                  Stock or any of their respective affiliates;

         -        any material transaction between New United and any of its
                  officers or directors or family members or affiliates of such
                  persons, other than employment contracts entered into in the
                  normal course of business;

         -        an amendment to the certificate of incorporation of United
                  that would adversely affect the rights of New United or the
                  holders of New United Class C Common Stock prior to the
                  exchange of all shares of United Class A Common Stock for New
                  United Class A Common Stock pursuant to a certain exchange
                  agreement contemplated by the Merger Agreement;

         -        any issuance of preferred stock of United;

         -        any disposition of or waiver of rights with respect to any
                  indebtedness of UPC held by New United; or

         -        any change in New United's principal accounting firm.

         Under the certificate of incorporation of New United, if, prior to
such time as United is no longer subject to the change of control provisions of
the indentures described in section (c) of Item 6 of this Statement under
"Appraisal; Voting Rights," New United issues shares of New United Class B
Common Stock and such issuance, together with any prior issuances of New United
Class B Common Stock as to which the holders of New United Class C Common Stock
did not have purchase rights under the certificate of incorporation of New
United, results in the voting power held by the holders of New United Class C
Common Stock being reduced below 90% of the voting power held by the holders of
New United Class C Common Stock immediately prior to such issuance or the first
such issuance, each holder of shares of New United Class C Common Stock will be
entitled to acquire additional shares of New United Class C Common Stock from
New United that would restore the voting power of such holder of New United
Class C Common Stock to 100% of its voting power immediately prior to such
issuance or the first such issuance (whichever is greater). Holders of New
United Class C Common Stock may acquire such New United Class C Common Stock
pursuant to this purchase right by purchasing it from New United for cash or
other form of consideration acceptable to New United and/or exchanging shares
of New United Class A Common Stock on a one-for-one basis. The holders of New
United Class C Common Stock will not be entitled to the foregoing purchase
rights in respect of any issuance of New United Class B Common Stock in an
amount such that, immediately following such issuance, the persons who were
holders of equity securities immediately prior to such issuance then hold less
than 30% of the voting power of New United's outstanding equity securities
in the election of directors generally.

         The foregoing description of the Merger Agreement is qualified in its
entirety by reference to the text of the Merger Agreement which is incorporated
herein by reference as Exhibit 7(a) hereto.

         At the closing of the Merger, the Reporting Person will enter into the
Stockholders Agreement and Standstill Agreement described in Item 6 of this
Statement, the forms of which are attached as exhibits to the Merger Agreement.
The Merger Agreement provides that, pending the closing of the Merger or
termination of the Merger Agreement, the parties will abide by the terms
provided for the Stockholders Agreement and Standstill Agreement as if all
references therein to New United were references to United and all references to
New United Class C Common Stock were references to United Class B Common Stock;
except that (a) the maximum percentage of United Common Stock that Liberty and
its controlled affiliates will be permitted to acquire thereunder, on a fully
diluted basis, will be limited to the sum of (i) the percentage beneficially
owned by them immediately after the execution and delivery of the


                                  Page 6 of 20

Merger Agreement (including that represented by the Note Shares and the other
shares of United Class A Common Stock purchased by a subsidiary of Liberty from
United on December 3, 2001), plus (ii) the percentage represented by any shares
acquired by them from (x) other parties to the Stockholders Agreement, including
United, and (y) pursuant to a release agreement, dated February 22, 2001, among
UPC, United, Liberty and LMI (the "UPC Release"), plus (iii) the percentage
represented by an additional 20 million shares; and (b) the Note Shares and any
shares acquired by Liberty and its controlled affiliates in reliance on clause
(a)(iii) above will not be exchangeable for shares of United Class B Common
Stock pursuant to the share exchange right provided for in the Stockholders
Agreement. Further, pending the closing of the Merger or termination of the
Merger Agreement, Liberty and its affiliates will be entitled to vote their
shares of United common stock in their full discretion with respect to any
action or transaction that would have required the approval of the directors
elected by the holders of New United Class C Common Stock if taken by New United
or that would be inconsistent with the provisions of the Merger Agreement. If
the Merger Agreement is terminated prior to closing, then the parties will
negotiate in good faith to enter into a stockholders agreement similar to the
Stockholders Agreement and a standstill agreement similar to the Standstill
Agreement, modified as described in the second sentence of this paragraph. The
Stockholders Agreement and Standstill Agreement, the forms of which are
incorporated into this Statement as Exhibits 7(b) and 7(c) respectively, and the
descriptions thereof in Item 6 are hereby incorporated by reference into this
Item 4.

         On December 21, 2001, United, New United, Liberty  and another company
entered into a letter agreement(as amended through the date hereof, the "Letter
Agreement") in which United granted its revocable consent, for purposes of the
Merger Agreement, to a tender offer and consent solicitation for any and all of
United's $1,375,000,000 principal amount at maturity 10 3/4% Senior Secured
Discount Notes due 2008 of United (the "Senior Secured Notes") by a company (the
"Purchaser") in which Liberty would have a minority interest (the "Bond Offer
and Consent Solicitation"). United has agreed pursuant to the Letter Agreement
that, subject to the successful completion of the Bond Offer and Consent
Solicitation, it will extend the payment date for the balance of the
indebtedness evidenced by promissory notes in the aggregate principal amount of
$310,000,000 payable by a subsidiary of Liberty to a subsidiary of United until
the second anniversary of the earlier of the closing of the Merger or the
termination of the Merger Agreement, and has agreed that those notes may be
paid, in addition to the manner provided in the Merger Agreement, with Senior
Secured Notes. Liberty has agreed to sell and New United has agreed to purchase,
after the Merger and if the Bond Offer and Consent Solicitation is successfully
completed, Liberty's entire interest in the Purchaser. New United has also
agreed to purchase from Liberty, under certain circumstances, any Senior Secured
Notes that Liberty may acquire from the Purchaser through a prepayment or
redemption of securities of the Purchaser held by Liberty.

         The Reporting Person intends to continuously review its investment in
the Issuer, and may in the future (subject to the terms of the Merger Agreement)
determine to (1) acquire additional securities of the Issuer, through open
market purchases, private agreements or otherwise, (2) dispose of all or a
portion of its interest in the Issuer or (3) take any other available course of
action, which could involve one or more of the types of transactions or have one
or more of the results described in the next paragraph of this Item 4.
Notwithstanding anything contained herein, the Reporting Person specifically
reserves the right to change its intention with respect to any or all of such
matters. In reaching any decision as to its course of action (as well as to the
specific elements thereof), the Reporting Person currently expects that it would
take into consideration a variety of factors, including, but not limited to, the
following: (A) the Issuer's business and prospects; (B) other developments

         -        any action similar to any of those enumerated in this

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER.

         (a) The Reporting Person presently beneficially owns 23,013,354 shares
of United Class A Common Stock, which includes 9,859,336 shares of United Class
A Common Stock issuable upon conversion of shares of the United Class B Common
Stock held by the Reporting Person. As of August 31, 2001, the Issuer had
outstanding 86,030,256 shares of United Class A Common Stock (including
5,569,240 shares of United Class A Common Stock held by UPC, but not including
35,708 shares of United Class A Common Stock held by the Issuer as treasury
shares) and 19,027,134 shares of United Class B Common Stock according to
representations and warranties made by the Issuer in the Merger Agreement. Each
share of United Class B Common Stock is convertible into one share of United
Class A Common Stock at the election of the holder without consideration. Each
share of United Class A Common Stock has one vote per share, and each share of
United Class B Common Stock has ten votes per share. Accordingly, the Reporting
Person beneficially owns approximately 21.3% of the outstanding United Class A
Common Stock and 38.8% of the Issuer's outstanding voting power.

         Except as described on Schedule 3, which is incorporated herein, to the
knowledge of the Reporting Person, none of the Schedule 1 Persons beneficially
owns any shares of United Class A Common Stock.

         The Reporting Person may be deemed to be a member of a group with the
other parties to the Merger Agreement. The Reporting Person disclaims being a
member of any such group and disclaims beneficial ownership of any securities of
the Issuer held by any such other party.

                                  Page 8 of 20

         (b) Except as described in Item 4 above and Item 6 below, the Reporting
Person has the sole power to direct the voting of the Shares and to direct the
disposition of the Shares.

         (c) The information included in Items 3 and 6 is hereby incorporated by
reference into this Item 5(c).

         (d) None.

         (e) Not applicable.



ITEM 6.  CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT
         TO SECURITIES OF THE ISSUER.

         (a) Merger Agreement

         The information regarding the Merger Agreement included in Item 4 of
this Statement and the text of the Merger Agreement incorporated herein as
Exhibit 7(a) are hereby incorporated by reference into this Item 6(a).

         (b) Stockholders Agreement

         At the closing of the Merger, New United, Liberty and Liberty Global
(together with their permitted transferees, the "Liberty Parties") and certain
Founders (together with their permitted transferees, the "Founder Parties") will
enter into a Stockholders Agreement, the material terms of which include the
following:

         Limitations on Conversion. Until such time as the provisions of certain
outstanding indentures of United and certain of its subsidiaries that require
the issuer to offer to repurchase the bonds issued thereunder upon a change of
control of United are rendered inapplicable (either by redemption of the bonds
or defeasance, waiver or amendment of the relevant provisions of such
indentures) or such a change of control occurs, other than as a result of a
breach of the Standstill Agreement by Liberty, the Liberty Parties will not
convert any shares of New United Class C Common Stock into New United Class A
Common Stock if, after giving effect to the conversion, the Liberty Parties
would have more than 50% of the combined voting power of the New United Class A
Common Stock and New United Class B Common Stock outstanding or would have more
voting power than the New United Class A Common Stock and New United Class B
Common Stock owned by the Founder Parties. This limitation on the Liberty
Parties' right to convert (a) will terminate if the aggregate voting power of
the shares of New United Class A common stock and New United Class B common
stock beneficially owned by any person or group (other than a group that is
controlled by certain of the Founders and that consists solely of Founders)
exceeds either 50% of the total voting power of New United or the voting power
held by the Founder Parties and (b) will not apply to conversions made by the
Liberty Parties in connection with a sale or hedging transaction or any related
pledges of their shares.

         Change of Control Covenants. Subject to specified exceptions for
governmental licenses, New United will not take or permit any action that would
result in it being subject to any


                                  Page 9 of 20

covenants restricting the ability of United, New United or any of their
affiliates to effect a change of control, other than such covenants contained in
certain existing indentures to which United is currently subject, unless any
such change of control involving or caused by the action of any Liberty Party
(other than a tranfer of control, if control were obtained, by a Liberty Party
to a third party) is exempted from the application and effects of any such
restrictive covenants. New United will not take or permit any action to extend
or perpetuate the existing change of control covenants beyond the maturity date
of the bonds issued under its outstanding indentures.

         Rights of First Offer. Subject to specified exceptions, no Liberty
Party may transfer any shares of New United Class B or Class C Common Stock
except to permitted transferees, or convert any such shares to New United Class
A Common Stock, unless it first offers the Founders the opportunity to purchase
the shares, and no Founder Party may transfer any shares of New United Class B
Common Stock except to permitted transferees, or convert any such shares to New
United Class A Common Stock, unless it first offers the Liberty Parties the
opportunity to purchase the shares. If either the Liberty Parties or the Founder
Parties decline to exercise their right of first offer, then the party proposing
to transfer shares of New United Class B or Class C Common Stock to a third
party must convert the shares to New United Class A Common Stock immediately
prior to such transfer, unless, in the case of a proposed transfer by the
Founder Parties, the number of shares being transferred by all Founder Parties
to the same transferee represents at least a majority of all shares of New
United Class B Common Stock owned by the Founder Parties, their permitted
transferees, and any other person that the Founder Parties have designated to
purchase shares from the Liberty Parties pursuant to the Founder Parties' right
of first offer. Prior to any event that permits the conversion of New United
Class C Common Stock into New United Class B Common Stock, the number of shares
that the Liberty Parties may transfer to a third party, when taken together with
the number of shares of New United Class A Common Stock previously transferred
to a third party following their conversion from New United Class B or Class C
Common Stock, shall not exceed the number of shares of New United Class A Common
Stock acquired after the closing of the Merger from persons other than New
United (including upon conversion of New United Class C Common Stock) or the
Founder Parties, plus the number of shares of New United Class A Common Stock
that the Liberty Parties receive in the Merger upon conversion of any United
Class A Common Stock acquired after December 3, 2001.

         Permitted Transfers. The Liberty Parties and Founder Parties may
transfer their shares of New United Class B common stock and New United Class C
common stock to permitted transferees without having to first offer them to any
other party. The Founder Parties' permitted transferees include other Founders,
family members and heirs of the Founders and partnerships or trusts owned by or
for the benefit of the Founders. The Liberty Parties' permitted transferees
include Liberty and any entity controlled by Liberty. The parties may pledge
their shares of New United Class B and Class C Common Stock in loan and hedging
transactions; provided that the applicable pledgee does not become a registered
holder of the shares and agrees to comply with the right of first offer
provisions of the Stockholders Agreement, with shortened notice and exercise
periods, in connection with any foreclosure on the pledged shares. Pledges of
the Founders' shares that were in existence prior to May 25, 2001 are also
allowed under the agreement.

         Tag-Along Rights. If the Liberty Parties propose to transfer a majority
of their shares of New United Class B and Class C Common Stock to persons other
than permitted transferees, and


                                 Page 10 of 20

the Founder Parties do not purchase such shares, then the Founder Parties will
be entitled to transfer a proportionate amount of their shares of New United
Class B Common Stock to the same purchaser on no less favorable terms. If the
Founder Parties propose to transfer a majority of their shares of New United
Class B Common Stock to persons other than permitted transferees, and the
Liberty Parties do not purchase such shares, then the Liberty Parties will be
entitled to transfer a proportionate amount of their New United Class A, Class B
and/or Class C Common Stock to the same purchaser on no less favorable terms.

         Drag-Along Rights. If the Founder Parties propose to transfer a
majority of their New United Class B Common Stock to an unaffiliated third party
that is not a permitted transferee, and the Liberty Parties do not purchase such
shares, then the Founder Parties can require the Liberty Parties to transfer to
the same transferee on terms no less favorable than those on which the Founder
Parties transfer their shares, at the election of the Liberty Parties, either
(i) all of their shares of New United Class B and Class C Common Stock, (ii) all
of their New United common stock or (iii) a proportionate amount of each class
of New United common stock that they own; provided that the Liberty Parties will
be required to transfer all of their New United common stock if, in connection
with the proposed transfer by the Founder Parties, Mr. Gene W. Schneider, G.
Schneider Holdings, Co., The Gene W. Schneider Family Trust, Mr. Mark L.
Schneider and The MLS Family Partnership LP propose to transfer all shares of
New United common stock beneficially owned by them, which shares of common stock
include shares of New United Class B Common Stock representing at least 40% of
the greater of the number of shares of New United Class B Common Stock owned by
them on the date of the Stockholders Agreement and the number of shares of
United Class B Common Stock owned by them on June 25, 2000.

         Exchange of Shares. New United will, on request, permit Liberty and its
affiliates to exchange any shares of New United Class A Common Stock owned by
them for shares of New United Class C Common Stock, or, following the conversion
of New United Class C Common Stock, New United Class B Common Stock, on a
one-for-one basis. New United will, upon request and subject to applicable laws,
permit Liberty and its affiliates to exchange any shares of capital stock of
UPC, and any other affiliate of New United (which shares were acquired from UPC
or such affiliate), for shares of New United Class C Common Stock or, following
the conversion of the New United Class C Common Stock, New United Class B Common
Stock. Without limiting the generality of the foregoing, at anytime after UPC is
entitled to convert shares of its Series 1 Convertible Preference Shares held by
Liberty to UPC ordinary shares, (i) Liberty will be entitled to exchange such
shares for New United Class C Common Stock or, following the conversion of the
New United Class C Common Stock, New United Class B Common Stock, and (ii) New
United will be entitled to call such shares from Liberty in exchange for shares
of New United Class C Common Stock or, following the conversion of the New
United Class C Common stock, New United Class B Common Stock, provided such
exchange is tax-free to Liberty, in either case on terms specified in the
Stockholders Agreement.

         Termination. The tag-along provisions, the drag-along provisions and
the limitations on the conversion of shares of New United Class C common stock
into shares of New United Class A common stock terminate on June 25, 2010,
unless the Stockholders Agreement is terminated earlier. The Stockholders
Agreement will terminate as to any Liberty Party or Founder Party the voting
power of whose equity securities is reduced below 10% of the voting power of
United such party held on June 25, 2000. The Stockholders Agreement will
terminate in its entirety on the first to occur of (a) all of the Founders and
their permitted transferees or Mr. Gene W. Schneider and Mr. Mark L. Schneider


                                 Page 11 of 20

and their permitted transferees (other than the other Founders) holding less
than 40% of the greater of the number of shares of New United Class B Common
Stock owned by them on the date of the Stockholders Agreement and the number of
shares of United Class B Common Stock owned by them on June 25, 2000 (assuming
for such purpose that any shares transferred by such persons to a Liberty Party
continue to be owned by such person) or (b) the transfer by the Founder Parties
of a majority of their New United Class B Common Stock to one or more Liberty
Parties or one or more unaffiliated third parties.

         The foregoing description of the Stockholders Agreement is qualified in
its entirety by reference to the form of the Stockholders Agreement, which is
included in the Merger Agreement as exhibit 7.7 thereto and is incorporated
herein by reference as Exhibit 7(b) hereto. The Merger Agreement is incorporated
by reference as Exhibit 7(a) hereto.

         (c) Standstill Agreement

         At the closing of the Merger, New United, Liberty and Liberty Global
will enter into a Standstill Agreement, the material terms of which include the
following:

         Limitation on Acquiring Securities and Other Actions. The Liberty
Parties will not acquire common stock of New United in an amount that would
cause their percentage of the total common stock of New United outstanding, on a
fully-diluted basis, to exceed the greater of (a) the sum of (i) the percentage
beneficially owned by them immediately after the closing of the transactions
contemplated by the Merger Agreement, plus (ii) the percentage represented by
any shares acquired by them from (x) other parties to the Stockholders
Agreement, including New United, and (y) from UPC pursuant to the UPC Release,
plus (iii) the percentage represented by an additional 25 million shares;
provided that the number determined by clauses (a)(i) and (a)(iii) shall not
exceed 81%, and (b) the sum of 81% plus the percentage determined by clause
(a)(ii)(x). Liberty will not (a) solicit proxies with respect to New United's
voting securities, (b) form, join or participate in a group if such group's
ownership of New United voting securities would exceed the maximum share
ownership percentage described in this paragraph, unless certain Founders are
part of such group, (c) deposit any New United voting securities into a voting
trust or subject them to a voting agreement or similar arrangement, (d) solicit
or encourage offers for New United from persons other than Liberty Parties or
Founders or (e) call a meeting of stockholders or seek amendments to New
United's bylaws without the consent of New United's board of directors. Liberty
will not be in breach of the restrictions on its maximum share ownership if its
share ownership exceeds the maximum percentage specified solely because of any
action taken by New United in respect of which no Liberty Party takes any action
other than in its capacity as a holder of equity securities of New United,
including, for example, a tender offer by New United to acquire shares of its
common stock that Liberty elects not to accept or the issuance of a dividend by
New United payable in cash or stock that the Liberty Parties elect to receive in
stock.

         Appraisal; Voting Rights. No Liberty Party will exercise appraisal
rights as to any matter. Liberty will cause its shares to be present at meetings
of New United stockholders so as to be counted for quorum purposes. Except for
certain matters as to which Liberty or the directors elected by the holders of
New United Class C Common Stock have approval rights, whether under the New
United certificate of incorporation, the Standstill Agreement or other agreement
entered into in connection with the Merger Agreement, or which, pursuant to the
bylaws of New United are required to be approved by the board of directors prior
to being submitted to the stockholders (in any such case, if such approval has
not been obtained), Liberty will vote its shares of common stock on all matters
submitted to a vote of stockholders, other than the election or removal of
directors or a merger, sale or similar transaction involving New


                                 Page 12 of 20

United, either as recommended by New United's board of directors or in the same
proportion as all other holders of common stock of New United. Liberty will vote
its shares of New United common stock against any merger, consolidation,
recapitalization, dissolution or sale of all or substantially all of New
United's assets not approved by New United's board of directors.

         Until such time as the provisions of certain outstanding indentures of
United and certain of its subsidiaries that require the issuer to offer to
repurchase the bonds issued thereunder upon a change of control of United are
rendered inapplicable (either by redemption of the bonds or defeasance, waiver
or amendment of the relevant provisions of such indentures) or a change of
control occurs, other than as a result of a breach of the Standstill Agreement
by Liberty, Liberty will vote its shares in the election of directors in its
sole discretion. Following such time, Liberty will be entitled to nominate four
members of New United's board of directors or, if greater, a number equal to at
least 33 1/3% of New United's board of directors, and the Founder Parties will
be entitled to nominate the same number of directors. New United's board of
directors will nominate the remaining members of the board of directors. The
Liberty Parties will then be obligated to vote their shares of common stock of
New United in favor of such nominees to the board of directors and, unless
requested to do so by the Founders, will not vote to remove any board members
nominated by the Founders except for cause.


         Limitations on Issuing High Vote Securities. New United will not issue
any New United Class B Common Stock or other equity security having more votes
per share than New United Class A Common Stock, or rights to acquire any such
securities, other than to Liberty Parties and their controlled affiliates,
except that New United may issue up to an aggregate of 3 million shares of New
United Class B Common Stock upon exercise of options outstanding at the time of
the closing of the Merger or subsequently issued options, and New United may,
on a majority vote of its board of directors, issue preferred stock convertible
into New United Class B Common Stock (but with no other conversion rights, no
voting rights other than as are customary in preferred stocks and no special
rights), provided that such preferred stock cannot be so converted prior to
such time as United is no longer subject to the change of control provisions of
the indentures described above, and the total number of shares of New United
Class B Common Stock issuable upon conversion of such options and preferred
stock must be less than the number of shares that would, if issued after such
time as United is no longer subject to such change of control provisions in
such indentures, entitle the Liberty Parties to exercise the purchase rights
described below.

         Limitations on Transfer. Subject to certain exceptions, no Liberty
Party may transfer any equity securities of New United, unless the transfer is
(i) to Liberty or a controlled affiliate of Liberty that is or becomes a party
to the Standstill Agreement, (ii) to one more underwriters in connection with a
public offering, (iii) to one or more Founders or purchasers designated thereby
pursuant to the right of first offer provisions of the Stockholders Agreement,
provided that any such transferee, if other than a Founder, becomes subject to
the Stockholders Agreement and, if other than a Founder or


                                 Page 13 of 20

permitted transferee of a Founder, the Standstill Agreement, (iv) pursuant to
the tag-along and drag-along provisions of the Stockholders Agreement or (v)
otherwise made in accordance with the provisions of the Stockholders Agreement;
provided that in the case of a transfer pursuant to clause (ii) or (v), if the
transfer is to a non-affiliate, the transferring Liberty Party has no reason to
believe that any person or group would obtain more than ten percent of New
United's voting power in the election of directors as a result of the transfer.
The Liberty Parties may pledge their equity securities to financial institutions
in connection with loan and hedging transactions that comply with the
Stockholders Agreement.

         Offers for New United. If any person makes an offer to (i) acquire
equity securities of New United from New United or from one or more of its
stockholders by public offer, (ii) acquire all or substantially all of New
United's assets or (iii) effect a merger, consolidation, share exchange or
similar transaction, New United will give Liberty notice of such offer promptly
upon receipt thereof, or, if giving such notice would violate any applicable law
or agreement, promptly after public announcement of such offer. In no event will
New United give Liberty notice of such an offer less than 10 days prior to
accepting it. If New United does not reject such an offer within 5 days, then
any Liberty Party or its affiliates may propose a competing offer to New
United's board of directors, and the board of directors will in the exercise of
its fiduciary duties consider in good faith waiving any provision of the
Standstill Agreement that would restrict actions that might be taken by a
Liberty Party or its affiliates in support of such a competing offer.

         If New United proposes to sell all or substantially all of its assets,
effect a merger, consolidation, share exchange or similar transaction or issue
New United Class B Common Stock in an amount  sufficient that Liberty would not
be entitled to exercise its purchase rights described below, then New United
will give Liberty notice of such proposal and will give Liberty an opportunity
to propose an alternative transaction to New United's board of directors.

         Purchase Right. If, following such time as United is no longer subject
to the change of control provisions of the indentures described above under
"Appraisal; Voting Rights," New United issues equity securities having more
votes per share than the New United Class A Common Stock and such issuance,
together with any prior issuance of high vote securities as to which the
Liberty Parties did not have purchase rights, results in the voting power of
the Liberty Parties' equity securities being reduced below 90% of their voting
power prior to such issuance or the first such issuance, the Liberty Parties
will be entitled to acquire a number of additional shares of New United Class B
Common Stock from New United that would restore the Liberty Parties' voting
power to 100% of what it was prior to such issuance or the first such issuance
(whichever is greater). Liberty may acquire such New United Class B Common
Stock by purchasing it from New United for cash or other form of consideration
acceptable to New United and/or by exchanging shares of New United Class A
Common Stock on a one-for-one basis. The Liberty Parties will not be entitled
to the foregoing purchase rights in respect of any issuance of New United Class
B Common Stock in an amount such that, immediately following such issuance, the
persons who were holders of equity securities immediately prior to such
issuance then hold less than 30 percent of the voting power of New United's
outstanding equity securities in the election of directors generally.

         Preemptive Right. If, at any time after the signing of the Standstill
Agreement, New United proposes to issue any New United Class A Common Stock or
rights to acquire New United Class A Common Stock, the Liberty Parties will have
the right, but not the obligation, to


                                 Page 14 of 20

purchase a portion of such issuance sufficient to maintain their then existing
equity percentage in New United on terms at least as favorable as those given to
any third party purchasers. This preemptive right will not apply to (i) the
issuance of New United Class A Common Stock or rights to acquire New United
Class A Common Stock in connection with the acquisition of a business from a
third party not affiliated with New United or any Founder, which business is
directly related to the then existing business of New United and its
subsidiaries, (ii) the issuance of options to acquire New United Class A Common
Stock to employees pursuant to employee benefit plans approved by New United's
board of directors (such options and all shares issued pursuant thereto not to
exceed 10% of New United's outstanding common stock), (iii) equity securities
issued as a dividend on all equity securities or upon a subdivision or
combination of all outstanding equity securities, or (iv) equity securities
issued upon the exercise of rights outstanding as of the closing of the Merger
or as to the issuance of which the Liberty Parties had the right to exercise
their preemptive rights.

         Termination. The Standstill Agreement will terminate on June 25, 2010,
except for the restrictions on New United's ability to issue additional high
vote securities and the Liberty Parties' purchase and preemptive rights;
provided that the Agreement will terminate in its entirety upon termination of
the Stockholders Agreement.

         The foregoing description of the Standstill Agreement is qualified in
its entirety by reference to the form of the Standstill Agreement, which is
included in the Merger Agreement as exhibit 7.10 thereto and is incorporated
herein by reference as Exhibit 7(c) hereto. The Merger Agreement has been
incorporated herein by reference as Exhibit 7(a) to this Statement.
