and accepted by Verio during the term of this Agreement. Commissions will not be

    this Agreement.

    (c) Verio shall provide to Web Agent a commission statement containing a
    mathematical representation of the calculation of the commission due to Web
    Agent, including any appropriate deductions, discounts and adjustments,
    under this Section 9 and in accordance with Exhibit 1.

    (d) The remuneration structure in this Section 9 is agreed to be the sole
    compensation and remuneration to Web Agent for the performance of its
    services under this Agreement.

    (e) If at any time during the term of this Agreement, customers originated
    by Web Agent (as determined pursuant to Exhibit 1) are greater than or equal
    to twenty-five (25) at the end of a calendar month, Web Agent will be
    designated a "Medallion Web Agent." If at any time during the term of this
    Agreement, customers originated by Web Agent are less than twenty- five
    (25), Web Agent shall lose its designation as a "Medallion Web Agent" until
    such time that customers originated by Web Agent are twenty-five (25) or
    more in a calendar month. If upon the expiration or termination of this
    Agreement for any reason Web Agent is a

<PAGE>

    "Medallion Web Agent", Web Agent shall be eligible for the "Residual
    Option." The "Residual Option" provides that Verio shall have the right to
    elect, in its sole discretion, either to (1) continue paying the Fixed
    Commission due and owing on an monthly basis for customers originated by Web
    Agent during the term of the Agreement until the expiration of the service
    agreements for such customers ("Option 1") or (2) pay Web Agent a onetime
    payment ("Option 2"). Option 2 will be calculated by multiplying eighteen
    (18) by the applicable monthly service charge for Services listed on Exhibit
    1 generated by customers originated by Web Agent in the month prior to the
    expiration or termination of the Agreement ("Residual Revenue") and
    multiplying the Residual Revenue by the applicable commission percentage
    ("Residual Commission") as set forth on Exhibit 1. Verio reserves the right
    to apply either Option 1 or Option 2 above to any combination of customers
    generated by Web Agent prior to the expiration or termination of this
    Agreement. If at the end of the initial two-year term or any Extension of
    this Agreement, customers originated by Web Agent are twenty-four (24) or
    less, Verio shall not extend this Agreement. Verio reserves the right, in
    its sole discretion, to discontinue the payment of commissions for any such
    customers and Verio shall have no further obligations to Web Agent for any
    commissions under this Agreement.

shall be for Web Agent's account. Web Agent shall not be entitled to
reimbursement from Verio for any such expenses and shall hold Verio harmless
therefrom.

behalf of Verio. Web Agent may, however, hold itself out specifically as a
value-added "Authorized Web Agent" of Verio in the course of fulfilling its
obligations hereunder. Furthermore, it is agreed that neither party is a
fiduciary or quasi-fiduciary of the other. Accordingly, it is agreed that
nothing in this Agreement shall be (i) construed as constituting Web Agent as

originated by Web Agent RELATIVE TO VERIO's SERVICES PURSUANT TO THIS AGREEMENT
and all information relating to such customers, and all of Verio's other
property and assets in the Territory. Verio shall maintain its absolute and
unrestricted right to manage its business, to sign all documents on its behalf,
to decide on its behalf, and to carry on its business separately and solely
according to its full power and discretion. Web Agent shall have no powers to
enter into any agreements for or on behalf of Verio.

(c) Each party agrees to indemnify, defend, save and hold the other party
harmless from and against all liabilities, damages, judgments, claims, costs and
expenses, including, but not limited to, reasonable attorneys' fees incurred by
the other party, as a result of or arising out of any breach of obligation,
warranty or representation in this Agreement by the other party ("Claim"). Each
party shall have the right to defend itself against any such Claim.

or other representatives, and to appoint other authorized sales representatives,
both within and outside of the geographic areas in which Web Agent operates.

and marketing materials, maintenance techniques, credit policies, advertising,
promotions, marketing techniques and prices, or to Verio's customers developed
by Web Agent during the course of this Agreement (collectively "Verio
Confidential Information"), shall be deemed to be confidential to Verio and
shall remain the exclusive property of Verio during and after the term of this
Agreement. Web Agent acknowledges and agrees that Verio Confidential Information
has been developed by Verio through substantial expenditures of time, money and
effort and constitutes unique and valuable property of Verio. Web Agent shall
keep in strict secrecy and confidence all Verio Confidential Information and
shall not during the term of this Agreement or thereafter use Verio Confidential
Information for its own benefit or disclose or permit any of its employees or
agents to disclose, through any medium, Verio Confidential Information to any
other person.

(b) Upon termination or expiration of this Agreement or upon request, Web Agent
shall return all Verio Confidential Information to Verio and certify in writing
that it has returned all such information to Verio and has not kept copies
thereof in any medium.

(c) Web Agent agrees not to solicit any customers of Verio, whether or not
originated by Web Agent, for Web hosting, e-commerce and other Internet presence
services for a period of two (2) years after termination or expiration of this
Agreement

(a) Disclaimer of Warranties. Unless Verio notifies Web Agent otherwise, Verio
disclaims all warranties with regard to services rendered under this Agreement,
including all implied warranties of merchantability and fitness for a particular
purpose. Web Agent shall extend no warranties or guarantees without the
pre-approval OF Verio, orally or in writing, in the name of Verio or which would
bind Verio with respect to the performance, design, quality, merchantability, or
fitness for a particular purpose of the Service.

(b) Limitation of Liability. Neither Verio nor its BranchEs, subsidiaries,
suppliers OR parent corporations shall be liable to Web Agent or any third party
for special, consequential, incidental, indirect, tort or cover damages,

use the services, delay of delivery and implementation, or loss of profits,
data, business or goodwill, whether or not such party has been advised or is
aware of the possibility of such damages. Verio'S liability for all claims of
any kind arising out of or relating to this Agreement shall be limited solely to
money damages and shall not exceed the amount of commissions due Web Agent.

(c) No Liability for Expiration or Lawful Termination. Neither party shall have
the right to recover damages or to indemnification of any nature, whether by way

made in connection with the business contemplated by this Agreement, due to the
expiration or permitted or lawful termination of this Agreement. EACH PARTY

        evidence of insolvency; or

        (iii) Verio is unable to provide the Service by reason of any law, rule,
        regulation, or order of any municipal, state or federal authority,

the highest applicable Tax rate, in each case in effect with respect to that Tax
for the Taxable period or any portion of the Taxable period to which the

Adjustment. For purposes of determining such additional Taxes incurred or to be
incurred, the following assumptions will be used: (a) in the case of any Income
Tax, the highest marginal Tax rate or, in the case of any other Tax, the highest
applicable Tax rate, in each case in effect with respect to that Tax for the
Taxable period or any portion of the Taxable period to which the indemnification
payment relates; and (b) such determination shall be made without regard to
whether any actual additional Taxes will in fact be realized with respect to the

             CONTRIBUTIONS, REORGANIZATION AND RELATED TRANSACTIONS

         2.1 Pre-Closing Restructuring Transactions. Prior to and as a condition
precedent of the Closing, the parties shall effect or cause to be effected the
following transactions:

                  (a) Each of the Founders will contribute, convey, transfer,
assign and deliver, free and clear of all Liens and Restrictions, except as set
forth in Section 5.7 of the Founders Disclosure Schedule, all and not less than
all of the shares of United Class B Stock held by such Founder as indicated next
to such Founder's name on Schedule 2.1(a) (collectively, the "Founder Shares"),
in each case together with the right to receive all unpaid dividends and
distributions declared or otherwise payable with respect to such Founder Shares
and associated stock purchase rights, if any, to newly-formed single-member
limited liability companies organized under the laws of the State of Delaware
(each a "Founder Newco"). At all times from the organization of each Founder
Newco until the Closing (i) no Person other than the Founder contributing shares
of United Class B Stock to such Founder Newco shall own any equity interest
whatsoever in such Founder Newco, (ii) the limited liability company membership
interests in such Founder Newco shall be owned by the applicable Founder free
and clear of any Liens and Restrictions, and such Founder Newco shall have no
assets, other than Founder Shares and shares of United Class A Stock issued to
such Founder Newco upon conversion of Founder Shares pursuant to the following
sentence, and no liabilities or obligations, known or unknown, whether absolute,
accrued, fixed, contingent or otherwise, other than its obligations under the
applicable Founder Newco Merger Agreement. Each Founder will cause its
applicable Founder Newco to convert an adequate number of the Founder Shares
held by it into an equal number of shares of United Class A Stock in order to
ensure that, after giving effect to the Founder Newco Mergers and the
contribution contemplated by Section 2.2(a), New United will not own 50% or more
of the voting power of United prior to the consummation of the United/New United
Merger.

                  (b) Gene W. Schneider ("Schneider"), as the sole stockholder
of New United, will cause the Certificate of Incorporation ("New United
Charter") and By-laws ("New United By-laws") of New United to be restated as set
forth in Exhibits 2.1(b)-1 and 2.1(b)-2, respectively.

                  (c) Immediately prior to the Closing, one or more Controlling
Principals will purchase from United an aggregate of 1,500 shares of United
Series E Preferred Stock for the purchase price set forth in, and otherwise
pursuant to the terms of, one or more Subscription Agreements between each such
Controlling Principal and United, in the form attached hereto as Exhibit 2.1(c)
(each a "Subscription Agreement").

         2.2 Contributions and Restructuring. At the Closing, upon the terms and
subject to the conditions set forth in this Agreement and in the order set forth
below (and otherwise substantially concurrently):

                  (a) (i) Schneider will contribute, convey, transfer, assign
and deliver to New United, free and clear of all Liens and Restrictions, one
share of United Class A Stock, together with the right to receive all unpaid
dividends and distributions declared or otherwise payable with respect to such
share of United Class A Stock and associated stock purchase rights, if any, as a
contribution to the capital of New United, and New United shall accept such
share of United Class A Stock as a contribution to its capital and Schneider
shall not receive any other consideration in exchange for such contribution,
(ii) Liberty Global will contribute, convey, transfer, assign and deliver, or
cause to be contributed, conveyed, transferred, assigned and delivered, to New
United, free and clear of all Liens and Restrictions, all, but not less than
all, of the shares of United Class B Stock held by Liberty Global as indicated
next to Liberty Global's name on Schedule 2.2 hereto (the "Liberty Global
Shares"), together with the right to receive all unpaid dividends and
distributions declared or otherwise payable with respect to such Liberty Global
Shares and associated stock purchase rights, if any, and New United shall accept
all, but not less than all, the Liberty Global Shares and issue and deliver to
Liberty Global, or to the applicable Contributing Party or Contributing Parties,
in exchange therefor a number of shares of New United Class C Stock equal to the
number of Liberty Global Shares so contributed (the "Liberty Global
Consideration Shares"), (iii) Liberty will contribute, convey, transfer, assign
and deliver, or cause to be contributed, conveyed, transferred, assigned and
delivered, to New United, free and clear of all Liens and Restrictions, all, but
not less than all, of the Note Shares, together with the right to receive all
unpaid dividends and distributions declared or otherwise payable with respect to
such Note Shares and associated stock purchase rights, if any, and New United
shall accept all, but not less than all, the Note Shares and issue and deliver
to Liberty, or to the applicable Contributing Party or Contributing Parties, in
exchange therefor a number of shares of New United Class C Stock equal to the
number of Note Shares so contributed (the "Liberty Consideration Shares") and
(iv) New United will convert the Liberty Global Shares into an equal number of
shares of United Class A Stock. Immediately prior to the contributions described
in clauses (ii) and (iii) of the previous sentence, there shall be no
outstanding shares of capital stock or other securities or ownership interests
of New United other than one share of New United Class A Stock held,
beneficially and of record, by Schneider.

                  (b) The Founders and New United will cause each of the Founder
Newcos to merge with and into New United (each, a "Founder Newco Merger") with
the limited liability company membership interests of each Founder Newco being
converted into an aggregate

                                       14
<PAGE>

number of shares of New United Class B Stock equal to the number of shares of
United Common Stock held by such Founder Newco at the time of such mergers (the
"Founder Consideration Shares"). Each of these mergers will be consummated
pursuant to an Agreement and Plan of Merger substantially in the form attached
hereto as Exhibit 2.2(b) (each, a "Founder Newco Merger Agreement"). Prior to or
simultaneous with the Founder Newco Mergers, any Liens and Restrictions on
shares of United Common Stock held by each Founder Newco, including as set forth
in Section 5.7 of the Founder Disclosure Schedule, shall be fully and
unconditionally released (without any liability whatsoever to New United or any
of its Subsidiaries or Affiliates) in accordance with instruments and documents
that are reasonably satisfactory to New United and the Liberty Parties and, from
and after the Founder Newco Mergers, such shares of United Common Stock shall be
free and clear of any Liens or Restrictions whatsoever. New United will be the
surviving entity in each of the Founder Newco Mergers.

                  (c) United, New United and United/New United Merger Sub shall
effect the United/New United Merger, as described in Section 2.5 below.

                  (d) Liberty Media will contribute, convey, transfer, assign
and deliver, or cause to be contributed, conveyed, transferred, assigned and
delivered, to New United, free and clear of all Liens and Restrictions:

                           (i)      all of the Belmarken Notes (or any proceeds
                                    thereof) and all of Liberty Sub's rights and
                                    obligations under the Belmarken Loan
                                    Agreements; and

                           (ii)     an amount of cash equal to US $200,000,000
                                    (the "Cash Contribution"); and

                           (iii)    all of the Liberty UPC Bonds or, in the
                                    event of any refinancing or restructuring
                                    of, or similar transaction with respect to,
                                    any of UPC's indebtedness, the proceeds, if
                                    any, received in exchange for any of the
                                    Liberty UPC Bonds in such transaction (the
                                    "Restructuring Proceeds");

and New United shall issue and deliver to Liberty Media or the applicable
Contributing Party or Contributing Parties at the Closing, the following shares
of New United Class C Stock (the "Liberty Contribution Shares"):

                                    Liberty Sub's rights and obligations under

                                    pursuant to Section 2.2(d)(i), a number of

                                    interest accrued on such amount from and

                                    of New United Class C Stock equal to the
                                    quotient of (A) the Liberty UPC Bond Cost
                                    divided by (B) US $1.53;

provided that (A) if the quotient obtained by dividing the sum of the Belmarken
Notes Value plus the amount of the Cash Contribution plus the Liberty UPC Bond
Cost plus US $20,000,000 (such sum, the "Liberty Contribution Value"), by the
sum of the total number of Liberty Contribution Shares determined in accordance
with clauses (1), (2) and (3) above plus 11,976,048 (such sum, the "Total
Liberty Shares"), is greater than US $5.00, New United shall issue and deliver
to Liberty at the Closing a sufficient number of additional shares of New United
Class C Stock (the "Additional Liberty Shares") so that the quotient obtained by
dividing the Liberty Contribution Value by the sum of the Total Liberty Shares
plus the Additional Liberty Shares is equal to US $5.00 and (B) if the quotient
obtained by dividing the Liberty Contribution Value by the Total Liberty Shares
is less than US $5.00, the number of Liberty Contribution Shares issued and
delivered by New United to Liberty pursuant to this Section 2.2(d) shall be
reduced by a number of shares of New United Class C Stock so that the quotient
obtained by dividing the Liberty Contribution Value by the number of Liberty
Contribution Shares issued and delivered to Liberty by New United is equal to US
$5.00. For purposes of each provision of this Agreement other than this Section
2.2(d) any Additional Liberty Shares issued and delivered pursuant to this
Section 2.2(d) shall be deemed to be Liberty Contribution Shares.

                  (e) Liberty Media, LMI and New United will enter into an
agreement pursuant to which New United will acknowledge that Liberty, LMI and
their respective Affiliates are intended beneficiaries of the covenants and
agreements set forth in Sections 7.11 and 11.15 of the Loan Agreement, dated as
of May 25, 2001, among Belmarken Holding B.V., UPC, UPC Internet Holding B.V.
and Liberty Sub, and New United will agree that it will not amend, modify or
waive in any respect or terminate any of such covenants or agreements without
the prior written consent of Liberty and LMI (the "No Waiver Agreement").

                  (f) If Liberty or Liberty Global causes any Person to make all
or part of the contributions described in clauses (a) or (d) above, each such
Person shall become a party to this Agreement and the applicable Transaction
Documents (each such Person, a "Contributing Party").

         2.3 Repayment of Indebtedness.

                  (a) Except as contemplated by the Notes Tender Letter
Agreement, at the Closing, immediately following the consummation of the
transactions set forth in Section 2.2, or such later date as may be acceptable
to United, Liberty shall repay, or cause to be repaid, in full the unpaid
balance of the principal amount of the $310,000,000 Notes together with all
accrued and unpaid interest thereon (the "Note Repayment Amount") to UIPI either
by the delivery of cash or, as described below, Liberty 2009 Notes, or such
other form of consideration as may be acceptable to United. Upon receipt of the
Note Repayment Amount or, if earlier, upon the assumption by New United of the
obligations represented by the $310,000,000 Notes, United shall irrevocably
release, and shall cause each of its Controlled Affiliates that is a beneficiary
of Liberty Media's guaranty of the repayment of the indebtedness evidenced by
the $310,000,000 Notes (the "Liberty Guaranty") to irrevocably release, Liberty
from all of its obligations under the Liberty Guaranty. Notwithstanding anything
contained in the December 7 Letter Agreement, the $310,000,000 Notes or the
Liberty Guaranty and except as contemplated by the Notes Tender Letter
Agreement, (i) the balance of the indebtedness evidenced by the $310,000,000
Notes shall not be due and payable until the Closing Date or such later date as
may be acceptable to United or as contemplated by the Notes Tender Letter
Agreement; provided, however, that if this Agreement is terminated without the
occurrence of the Closing, then, except as contemplated by the Notes Tender
Letter Agreement, the balance of such indebtedness will be due and payable in
cash on the date of termination of this Agreement or such later date as may be
acceptable to United, (ii) prior to the Closing, Liberty Argentina may assign
the $310,000,000 Notes, in whole or in part, to Liberty and (iii) Liberty may
repay, or cause to be repaid, the balance of the indebtedness evidenced by the
$310,000,000 Notes, in whole or in part, by the delivery of Liberty 2009 Notes,
or such other form of consideration as may be acceptable to United or as
contemplated by the Notes Tender Letter Agreement, to UIPI at the Closing or
such later date as may be acceptable to United or as contemplated by the Notes
Tender Letter Agreement. If Liberty repays, or causes to be repaid, any or all
of the balance of the indebtedness evidenced by the $310,000,000 Notes by the
delivery of Liberty 2009 Notes, (A) such Liberty 2009 Notes shall (1) except as
set forth herein, be substantially identical to Liberty's Senior Notes, due
2009, that were originally issued on July 7, 1999 (the "Existing Liberty
Notes"), (2) not, when delivered to UIPI, be registered pursuant to the
Securities Act, (3) be issued with an aggregate principal amount equal to the
portion of the Note Repayment Amount that is being repaid by delivery of such
Liberty 2009 Notes, and (4) bear interest on the principal amount thereof at a
rate per annum equal to the market yield on the Existing Liberty Notes as of the
date such Liberty 2009 Notes are delivered to UIPI (determined in the manner set
forth on Schedule 2.3), and (B) Liberty, United and UIPI shall, in connection
with any such delivery of Liberty 2009 Notes, enter into a registration rights
agreement with respect to the Liberty 2009 Notes in the form attached hereto as
Exhibit 2.3 (the "Liberty 2009 Notes Registration Rights Agreement").

                  (b) (i) United shall not and shall cause each of its
Subsidiaries at any time holding Liberty 2009 Notes not to, transfer any Liberty
2009 Notes to any Person other than a Person that is a wholly owned Subsidiary
of United without first complying with the provisions of this Section 2.3(b). If
United or a United Subsidiary holding any Liberty 2009 Notes (the "Notes
Holder") desires to transfer any Liberty 2009 Notes to a Person that is not a
wholly owned Subsidiary of United, such Notes Holder shall first deliver written
notice to Liberty by telecopy (a "Liberty Notice") on the fifth Business Day
prior to the date on which the Notes

                                       17
<PAGE>

Holder intends to transfer such Liberty 2009 Notes (the "Transfer Date"),
setting forth the number of Liberty 2009 Notes such Notes Holder intends to
transfer on the Transfer Date (expressed as an aggregate principal amount) and
setting forth a time on the Transfer Date at which the Notes Holder will deliver
the Offer Notice telephonically as described in the following sentence, which
time shall be after 7:00 a.m. and prior to 8:00 a.m. (in each case, Denver,
Colorado time). On the Transfer Date, at the time set forth in the Liberty
Notice, the Notes Holder shall telephonically offer (the "Offer Notice") to sell
Liberty a number of Liberty 2009 Notes (expressed as an aggregate principal
amount) equal to the number of Liberty 2009 Notes set forth in the Liberty
Notice (the "Offered Notes"), free and clear of all Liens and Restrictions, for
cash in an amount per Liberty 2009 Note specified by the Notes Holder (expressed
as a percentage of the principal amount of each Liberty 2009 Note so offered).

                    (ii) If Liberty desires to purchase all, but not less than
all, of the Offered Notes, Liberty may accept such Offer Notice by notifying the
Notes Holder telephonically at the telephone number specified in the Offer
Notice at or prior to 10:00 a.m. (Denver, Colorado time) on the Transfer Date of
its intention to purchase the Offered Notes (the "Purchased Notes") for a cash
purchase price per Purchased Note as set forth in the Offer Notice (the
"Acceptance Notice"). The telephonic delivery of a timely Acceptance Notice
shall constitute a binding obligation of Liberty and the Notes Holder. Liberty
and the Notes Holder shall, on the Transfer Date and promptly following the
telephonic delivery of an Acceptance Notice, execute and deliver a customary
agreement for the purchase and sale of the Purchased Notes, which agreement
shall contain representations and warranties on the part of the Notes Holder
that the Purchased Notes are, and will be at the closing of the sale of the
Purchased Notes to Liberty, owned by such Notes Holder, beneficially and of
record, and are not, and at the time of such closing will not be, subject to any
Liens or Restrictions whatsoever. The sale of the Purchased Notes to Liberty
shall be consummated on the third Business Day following the Transfer Date.

                    (iii) If Liberty does not telephonically deliver an
Acceptance Notice to the Notes Holder agreeing to purchase all of the Offered
Notes, the Notes Holder may, on the Transfer Date, sell all, but not less than
all, the Offered Notes for a cash purchase price per Offered Note that is no
less than the purchase price per Offered Note set forth in the Offer Notice to a
bona fide third party. Any sale of Offered Notes pursuant to the previous
sentence shall be consummated no later than the third Business Day following the
Transfer Date. If the Notes Holder does not sell the Offered Notes on the
Transfer Date or does not consummate the sale thereof on or before the third
Business Day following the Transfer Date, the Offered Notes may not be
transferred without again complying with the procedures set forth in this
Section 2.3(b).

         2.4 Certain Adjustments. If at any time after the Original Agreement
Date United or New United effects any stock dividend, stock split, reverse stock
split, recapitalization or reclassification affecting the shares of its common
stock or preferred stock of any class or series, or otherwise effects any
transaction that changes such shares into any other securities (including
securities of another entity) or effects any other dividend or distribution
(other than a normal cash dividend payable out of current or retained earnings)
on such shares, then the exchange ratios (including the number and kind of
shares) set forth in this Agreement for any transaction not consummated prior to
such event will, as appropriate, be adjusted to reflect such event.

cancellation or acceleration) under, or result in a Lien on any of the assets of

                                    the industries in which United and its
                                    Subsidiaries operate generally (none of
                                    which has resulted or is reasonably likely
                                    to result in a United Material Adverse
                                    Effect or a New United Material Adverse
                                    Effect).

                  (h) Absence of Certain Developments. Since June 30, 2001,
other than as otherwise permitted, contemplated or required by this Agreement or
the other Transaction Documents, (x) the business of United and each of its
Subsidiaries has been operated only in the ordinary course, (y) to United's
knowledge, except to the extent disclosed in Section 6.1(h) of the United
Disclosure Schedule, no event has occurred and no condition exists that,
individually or together with other events and conditions, has had or, insofar
as United can reasonably foresee, is reasonably likely to have, a United
Material Adverse Effect or a New United Material Adverse Effect, and (z) there
has been no material change in the accounting methods, practices or policies of
United or any of its Subsidiaries except as required by changes in GAAP.

                  (i) Legal Compliance. Except as set forth in the United 2001
Commission Filings or in Section 6.1(i) of the United Disclosure Schedule,
United and its Subsidiaries (x) are in compliance with, and have conducted their
respective businesses so as to comply with, the terms of their respective
Licenses and all applicable Laws, and (y) have all Licenses that are required to
operate their respective businesses, except in such cases where the failure to
so comply or to have such Licenses, either individually or in the aggregate, has
not had and is not reasonably expected to have a United Material Adverse Effect
or a New United Material Adverse Effect. Without limiting the generality of the
foregoing, the operations of the businesses, assets and facilities of United
and, to United's knowledge, its Subsidiaries are in compliance with all
applicable Environmental and Health Laws, if any, except where the failure to
comply has not had and is not reasonably expected to have a United Material
Adverse Effect or a New United Material Adverse Effect.

                  (j) Taxes. Except as otherwise set forth in Section 6.1(j) of
the United Disclosure Schedule:

                           (i)      Each of United and each of United's
                                    Subsidiaries identified in Paragraph A. of
                                    Section 6.1(j) of the United Disclosure
                                    Schedule (the "Material United
                                    Subsidiaries") has timely filed all material
                                    Tax Returns that it was required to file.
                                    All such Tax Returns are true and complete
                                    in all material respects. All material Taxes
                                    owed by United and the Material United
                                    Subsidiaries (whether or not shown on any
                                    Tax Return) have been timely paid. There are
                                    no Liens for material Taxes (other than for
                                    current Taxes not yet due and payable or for
                                    items being contested in good faith and for
                                    which there are adequate reserves in
                                    accordance with GAAP on the books of the
                                    applicable entity) on any of the assets of
                                    United or the Material United Subsidiaries.

                           (ii)     Each of United and each of the Material
                                    United Subsidiaries has withheld and paid
                                    all material Taxes required to have been

                                       38

                                    withheld and paid in connection with amounts
                                    paid or owing to any employee, independent
                                    contractor or other third party.

                           (iii)    No material deficiencies for any Taxes have
                                    been proposed, asserted or assessed against
                                    United or any of the Material United
                                    Subsidiaries that are not adequately
                                    reserved for in accordance with GAAP in all
                                    cases applied on a consistent basis. No Tax
                                    Returns of United or any of the Material
                                    United Subsidiaries are currently the
                                    subject of an audit.

                           (iv)     None of United or the Material United
                                    Subsidiaries has any current non-contingent
                                    liability for the Taxes of any Person (other
                                    than United and its Subsidiaries) under
                                    Treasury Regulations Section 1.1502-6 (or
                                    any similar provision of state, local, or
                                    foreign law), as a transferee or successor,
                                    by Contract, or otherwise.

                           (v)      If the income of United or any of the
                                    Material United Subsidiaries was required
                                    under federal, state, local, or foreign tax
                                    rules, to be included on a consolidated,
                                    unitary, combined or other such Tax Return
                                    filed by a Person other than any of United
                                    or the Material United Subsidiaries, each
                                    such group has filed all material Tax
                                    Returns that it was required to file with
                                    respect to United or any of the Material
                                    United Subsidiaries for each period during
                                    which United or any of the Material United
                                    Subsidiaries was a member of such group. All
                                    such material Tax Returns were correct and
                                    complete in all material respects insofar as
                                    they relate to United and the Material
                                    United Subsidiaries. All material Taxes owed
                                    by such group with respect to United and the
                                    Material United Subsidiaries (whether or not
                                    shown on a Tax Return) have been paid for
                                    each taxable period during which United or
                                    any of the Material United Subsidiaries was
                                    a member of its respective group.

                           (vi)     The normal period within which to examine
                                    and/or assess Taxes on the income of United
                                    or any of the Material United Subsidiaries
                                    has not been extended with respect to any
                                    such Person by waiver of, or agreement to
                                    extend, the applicable statute of
                                    limitations or otherwise.

                           (vii)    Neither United nor any of the Material
                                    United Subsidiaries has filed a consent
                                    under Section 341(f) of the Code.

                           (viii)   Neither United nor any of the Material
                                    United Subsidiaries has made any payments,
                                    nor are any of them obligated to make any
                                    payments, and none of them is a party to any
                                    agreement that under certain circumstances
                                    could obligate it to make any payments as a
                                    result of the transactions contemplated by
                                    this Agreement or the other Transaction

                           (ix)     United has not taken any action and has no
                                    present plan or intention to take any action

                           (xi)     Other than the Material United Subsidiaries,
                                    none of United's subsidiaries would,

                                    considered in the aggregate, constitute a
                                    "significant subsidiary" of United as such
                                    term is defined in Section 1-02(w) of
                                    Regulation S-X promulgated under the
                                    Exchange Act; provided that, for such
                                    purposes the term "5 percent" shall be
                                    substituted in each instance in which the
                                    term "10 percent" appears in Section 1-02(w)
                                    of Regulation S-X.

                  (k) Contracts and Commitments. Except for Contracts entered
into after June 30, 2001 that are disclosed in Section 6.1(k) of the United
Disclosure Schedule, all Contracts to which United or any of its Subsidiaries is
a party or by which any of them or their respective businesses or assets are
bound that are to be performed in whole or in part after the date hereof and
that are required to be filed with the Commission as "material contracts"
pursuant to Item 601 of Regulation S-K have been filed with the United 2001
Commission Filings. Except as disclosed in Section 6.1(k) of the United
Disclosure Schedule, there is no material Contract or Judgment binding upon
United or any of its Subsidiaries (i) that has had or could reasonably be
expected to have the effect of prohibiting or materially impairing any current
business practice of, or the conduct of business as currently conducted by,
United or its Subsidiaries or limiting the right of United or any of its
Subsidiaries to compete in any line of business, (ii) that purports to or would
bind New United or any of its Subsidiaries or any of the Liberty Parties or any
of their respective Affiliates after giving effect to the transactions
contemplated hereby or (iii) in respect of which, whether before or after giving
effect to the transactions contemplated hereby or by the other Transaction
Documents, any act or omission of any of the Liberty Parties or any of their
respective Affiliates would result in a violation or breach thereof, or
constitute (with or without the giving of notice or lapse of time or both), or
permit any Person to declare, a default or event of default thereunder, or give
rise to any right of termination, cancellation, amendment,

                                       40

thereunder, or give rise to or accelerate any obligation (including, without
limitation, any obligation to, or to offer to, repurchase, prepay, repay or make
increased payments) or result in the loss or modification of any rights or
benefits thereunder, or result in any Lien or Restriction on any of the assets
of, or otherwise have any material adverse effect on, United or any of its
Affiliates. True and complete copies of all Contracts listed in the United
Commission Filings or in Section 6.1(k) of the United Disclosure Schedule have
been provided to Liberty Media. Each of United and its Subsidiaries has
fulfilled in all material respects, or taken all actions necessary to enable it
to fulfill in all material respects when due, its obligations under each of such
Contracts to which it is a party, and none of United or any or its Subsidiaries
is in breach or violation of, or in default (with or without the giving of
notice or lapse of time or both) under any of such Contracts, which breach,
violation or default individually or in the aggregate would reasonably be
expected to have a United Material Adverse Effect or a New United Material
Adverse Effect.

                  (l) Intangible Property. Except as set forth in the United
2001 Commission Filings or Section 6.1(l) of the United Disclosure Schedule, one
or more of United and its Subsidiaries owns, or is licensed or otherwise
possesses legally enforceable rights to use, all Intellectual Property that is
used in the business of United and its Subsidiaries as currently conducted,
except to the extent that the failure to have such rights has not had and is not
reasonably likely to have a United Material Adverse Effect. Except as set forth
in the United 2001 Commission Filings or Section 6.1(l) of the United Disclosure
Schedule and except, in the case of clauses (iii) and (iv), to the extent that
any of the following has not had and is not reasonably likely to have a United
Material Adverse Effect, (i) neither United nor any of its Subsidiaries has
received notice of any claim of infringement of the rights of others with
respect to any patents, trademarks, service marks, trade names, copyrights or
other Intellectual Property used or owned by United or any of its Subsidiaries,
(ii) neither United nor any of its Subsidiaries has any knowledge that United or
any of its Subsidiaries is infringing upon or otherwise violating, or has
infringed upon or otherwise violated, the rights of any third party with respect
to any patent, trademark, trade name, service mark, copyright or other
Intellectual Property, (iii) no current or former employee of United or any of
its Subsidiaries is or was a party to any confidentiality agreement and/or

of any activity that such employee was hired to perform, and (iv) none of United
or any of its Subsidiaries is currently using or has in the past used without
appropriate authorization, any confidential information or trade secrets of any
third party. Since January 1, 1997, neither United nor any of its Subsidiaries
has received any notice alleging such conduct.

                  (m) Interested Party Transactions. Except to the extent
reflected in the United 2001 Commission Filings, Section 6.1(m) of the United
Disclosure Schedule lists all transactions between United or any of its
Subsidiaries, on the one hand, and any director, executive officer (or immediate
family member of such director or executive officer) or stockholder of United or
(other than United) any of its Subsidiaries, on the other hand, in which the

the transactions contemplated by the Stock Purchase Agreements, dated as of the

Amendment Date, United has provided Liberty Media with a true and complete copy
of the Stock Purchase Fairness Opinion, and Liberty Media hereby acknowledges
receipt thereof.

                  (r) Vote Required. The only vote of stockholders of United
required under the DGCL, NASD requirements and the certificate of incorporation
and bylaws of United in order to approve the transactions contemplated by this
Agreement and the other Transaction Documents is the affirmative vote in favor
of the United/New United Merger and the other transactions contemplated by this
Agreement and the other Transaction Documents of a majority of the total number
of votes entitled to be cast by the holders of the issued and outstanding shares
of United Class A Stock and United Class B Stock voting as a single class, and
no other vote or approval of or other action by the holders of any capital stock

                  (v) Priority Telecom. Neither United nor any of its

owned, leased or operated by it or the nature of the business conducted by it
makes such qualification necessary, except where the failure to be so duly
qualified or licensed and in good standing, individually or in the aggregate,
would not have (1) a Material Adverse Effect on New United and its Subsidiaries,
taken as a whole, or (2) a material adverse effect on the ability of New United
to perform its obligations under, and consummate the transactions contemplated
by, this Agreement and the other Transaction Documents (each of clauses (1) and
(2) above, a "New United Material Adverse Effect"). True and complete copies of
the New United Charter (in the form in which it will be restated pursuant to

                                    to which New United or any of its
                                    Subsidiaries is a party or by which New

delivering and performing their respective obligations under this Agreement and
the other Transaction Documents.

                                    no, and following the United/New United
                                    Merger, New United and its Subsidiaries will
                                    have no, liability, commitment or obligation

                                    or contingent or otherwise. As of

                                    contingent or otherwise, other than (i) in
                                    the case of Subsidiaries of New United,
                                    liabilities, commitments and obligations of
                                    Liberty Sub, which liabilities, commitments
                                    and obligations were in existence
                                    immediately prior to the Closing and (ii)
                                    liabilities, obligations and commitments of

                                    Agreement and the other Transaction
                                    Documents to which it is a party.

                  (h) Absence of Certain Developments. Since the date of the
most recent balance sheet included in the Available New United Commission
Filings, other than as otherwise permitted, contemplated or required by this
Agreement or the other Transaction Documents, (i) the business of New United and
each of its Subsidiaries has been operated only in the ordinary course, (ii) no
event has occurred and no condition exists that, individually or together with
other events and conditions, has had or, insofar as New United can reasonably
foresee, is reasonably likely to have, a New United Material Adverse Effect, and
(iii) there has been no change in the accounting methods, practices or policies
of New United or any of its Subsidiaries.

                  (i) Legal Compliance. New United and its Subsidiaries (x) are
in compliance with, and have conducted their respective businesses so as to
comply with, the terms of their respective Licenses and all applicable Laws, and
(y) have all Licenses that are required to operate their respective businesses,
except in such cases where the failure to so comply or to have such Licenses,
either individually or in the aggregate, has not had and is not reasonably
expected to have a New United Material Adverse Effect. Without limiting the
generality of the foregoing, the operations of the businesses, assets and
facilities of New United and its Subsidiaries are in compliance with all
applicable Environmental and Health Laws, if any, except where the failure to
comply has not had and is not reasonably expected to have a New United Material
Adverse Effect.

                  (j) Contracts; No Breach. Each of New United and its
Subsidiaries has fulfilled in all material respects, or taken all actions
necessary to enable it to fulfill in all material respects when due, its
obligations under each Contract to which it is a party or by which it or any of
its assets are bound and none of New United or any of its Subsidiaries is in
breach or violation of, or in default (with or without the giving of notice or
lapse of time or both) under, and no circumstance or condition exists that could
give rise to, or permit any other Person to, declare a default under, any of the
Contracts to which it is a party or by which it or its assets are bound, which
breach, violation or default individually or in the aggregate would reasonably
be expected to have a New United Material Adverse Effect.

                  (k) Section 203 and Similar Laws. Pursuant to the New United
Charter and the certificate of incorporation of United/New United Merger Sub,
neither Section 203 of the

                                       49
<PAGE>

Delaware General Corporation Law nor any similar provision of any other Law is
applicable to business combinations involving New United or any of its
Subsidiaries.

                  (l) No Investment Company. New United is not, and immediately
following the consummation of the transactions contemplated hereby and by the
other Transaction Documents New United shall not be, an "investment company"
subject to the registration requirements of, or regulation as an investment
company under, the Investment Company Act of 1940.

                  (m) Registration Statement; Proxy Statement. The Registration
Statement and the Proxy Statement, except for any information supplied by any
Liberty Party in writing expressly for purpose of inclusion therein, shall not
at the time the Registration Statement is declared effective by the Commission,
on the date the Proxy Statement is first mailed to the stockholders of United,
at the time of the United Stockholders Meeting or on the Closing Date contain
any untrue statement of a material fact or omit to state any material fact
required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading.

each case to the same extent as though the applicable agreement had been
executed and delivered by the parties thereto on the Original Agreement Date;

contrary, nothing contained in this Section 7.1(b) shall be deemed to (1)
restrict United, UPC, United A/P, UPC Polska, Inc. or Poland Communications,
Inc. or any of their respective "Subsidiaries" and "Restricted Affiliates" (as
such terms are defined in the indentures to which these Persons are party) from
taking any action if and to the extent that such a restriction would violate the
indentures binding on such Persons or (2) restrict UPC or any of its
Subsidiaries from taking any action if and to the extent that such a restriction
would violate the Belmarken Loan Agreements or UPC's Senior Secured Credit
Facility dated as of October 26, 2000. United shall promptly after obtaining
knowledge thereof notify Liberty of the occurrence of any event that
individually or together with any other event has had or is reasonably likely to
have a United Material Adverse Effect or New United Material Adverse Effect.

                  (c) Except as expressly contemplated by Section 2.1(a) hereof
and except with the prior written consent of each of United and the Liberty
Parties, no Founder or Founder Newco shall sell, transfer or otherwise dispose
of or create any Lien or Restriction on any limited liability company membership
interest in any Founder Newco or any of the shares of United Class B Stock or,
in the case of a Founder Newco, United Class A Stock owned by it or any interest
therein, or take or omit to take any action that would or could reasonably be
expected to result in the failure of the conditions precedent set forth in this
Agreement to the parties' obligations to consummate the transactions
contemplated hereby and by the other Transaction Documents to be satisfied. Each
Founder shall promptly after obtaining knowledge thereof notify each of United
and the Liberty Parties of the occurrence of any event that has had or is
reasonably likely to have a Founder Material Adverse Effect with respect to such
Founder.

                  (d) Each party hereto shall promptly give written notice to
the others upon becoming aware of the occurrence or, to its knowledge, impending
or threatened occurrence, of any event that is reasonably likely to cause or
constitute a breach of any of its representations, warranties or covenants
hereunder as if its representations or warranties were then being made.

                  (e) United shall not, and shall not permit any of its
Subsidiaries to, take any action to satisfy a UPC Stock Purchase Option (as
defined in the Priority Telecom Shareholders

                                       53
<PAGE>

Agreement) through the issuance or delivery of securities of United or any of
its Subsidiaries (including UPC but excluding Priority Telecom) without the
prior written consent of Liberty.

                  (f) United shall take or cause to be taken such action as may
be necessary to ensure that any default under or acceleration of any of the
liabilities of United A/P or any of its Subsidiaries, or a bankruptcy or similar
event involving United A/P or any of its Subsidiaries, at any time (whether
before or at any time after the Closing) would not (with or without the giving
of notice or lapse of time or both) result in the acceleration of, or give rise
to the right to accelerate, any of the indebtedness of United or any of its
Subsidiaries. Without limiting the generality of the foregoing, the parties
acknowledge that the covenant set forth in this Section 7.1(f) shall not be
satisfied if any Contract (including any Contract evidencing or relating to
indebtedness) to which United A/P or any of its Subsidiaries is or becomes a
party or pursuant to which any of their respective assets are or become bound
restricts in any manner the actions of, or imposes any obligation, liability or
commitment on, New United or any of its Subsidiaries or United or any of its
Subsidiaries except, in the case of United and its Subsidiaries, as disclosed on
Schedule 7.1(f). For purposes of this Section 7.1(f), the Subsidiaries of United
A/P shall include Austar United Communications Limited and its Subsidiaries.

                  (g) United shall take or cause to be taken such action as may
be necessary to exempt the Liberty Parties and their respective Affiliates from
the effect of any Contract among only United and one or more of its Controlled
Affiliates or among only Controlled Affiliates of United (i) that purports to or
would bind any of the Liberty Parties or any of their respective Affiliates
after giving effect to the transactions contemplated hereby or (ii) in respect
of which, whether before or after giving effect to the transactions contemplated
hereby, any act or omission of any of the Liberty Parties or any of their
respective Affiliates would result in a violation or breach thereof, or
constitute (with or without due notice or lapse of time or both), or permit any
Person to declare, a default or event of default thereunder, or give rise to any
right of termination, cancellation, amendment, acceleration, repurchase,
prepayment or repayment or to increased payments thereunder, or give rise to or
accelerate any obligation (including, without limitation, any obligation to, or
to offer to, repurchase, prepay, repay or make increased payments) or result in
the loss or modification of any rights or benefits thereunder, or result in any
Lien or Restriction on any of the assets of, or otherwise have any adverse
effect on, United or any of its Affiliates.

B.2. of Section 6.1(b) of the United Disclosure Schedule and (B) shall be
reduced by the number of shares of United Class A Stock underlying any options
granted after August 31, 2001 to the Amendment Date, all of which options United
represents and warrants comply with the provisions of this Section 7.1(h)
(including with respect to the exercise prices thereof) and (2) which, except
for any Class B Options described in paragraph B.2. of Section 6.1(b) of the
United Disclosure Schedule, may only be options to purchase shares of United
Class A Stock) (and no stock appreciation rights, restricted stock awards or any
other grants under United's 1993 Stock Option Plan or otherwise other than such
options to purchase shares of Common Stock) may be granted, provided that any
such option shall have a per share exercise

                                       54
<PAGE>

price equal to or greater than either (x) the per share average of the Closing
Prices for New United Class A Stock for the 30 consecutive Trading Days
beginning on and including the first Trading Day following the Closing Date or
(y) US $5.00 per share (unless a higher price is required pursuant to the terms
of the relevant United Stock Option Plan). Any such option shall specify (which
specification shall not be subject to change for any reason whatsoever), at the
time of the grant thereof, whether the exercise price thereof shall be as set
forth in clause (x) or (y) of the previous sentence.

                  (i) United shall promptly provide and shall use commercially
reasonable efforts to cause United A/P to promptly provide, Liberty with true
and complete copies of any notices or correspondence received by United or any
of its subsidiaries or by United A/P or any of its subsidiaries relating to any
default, acceleration or breach of, or potential default, acceleration or breach
of, or dispute regarding, any material Contract evidencing or securing any
outstanding indebtedness of United or any of its subsidiaries or United A/P or
any of its subsidiaries or pursuant to which any such outstanding indebtedness

connection with the transactions contemplated hereby or by the other Transaction
Documents, and shall submit the same to its stockholders for their approval.
United will, through its Board of Directors, recommend to its stockholders the

the United/New United Merger and each such other matter. Liberty Global will not
transfer record or beneficial ownership of any United Class B Stock prior to the
Closing except to a Controlled Affiliate of Liberty and unless the transferee,
simultaneous with such transfer, executes a counterpart to this Agreement and
thereupon becomes bound hereby to the same extent as Liberty Global (including
the obligation, subject to the satisfaction or waiver of the terms and
conditions of this Agreement, to take any actions that Liberty Global is
required to take at the Closing). No amendment to or modification or waiver of
any of the provisions of any of the Transaction Documents shall be authorized,
recommended or approved without the prior written consent of the Liberty
Parties.

Condition. United and New United shall respond promptly to any comments of the
Commission and shall use all commercially reasonable efforts to cause the Proxy

declared effective as promptly as practicable after such filing. Following the
effectiveness of the Registration Statement, United shall promptly mail the
definitive Proxy Statement to its stockholders. Each of United and New United
will notify the Liberty Parties promptly of the receipt of any comments from the
Commission or its staff or any other government officials and of any request by
the Commission or its staff or such other government officials for amendments or
supplements to the Registration Statement, the Proxy Statement or any filing
incorporated therein or for additional information, and will supply the Liberty
Parties with copies of all correspondence between it and any of its
representatives, on the one hand, and the Commission or its staff or any other
government officials on the other hand, with respect to the Registration
Statement, the Proxy Statement, the transactions contemplated by this Agreement

Registration Statement or any other filing with the Commission in connection
with this Agreement, the other Transaction Documents or the transactions
contemplated hereby or thereby, such party shall promptly inform the other
parties of such occurrence. United and New United shall promptly prepare and

the transactions contemplated hereby or thereby to comply in all material
respects with the applicable provisions of the Securities Act and the Exchange
Act. To the extent information regarding any Liberty Party or any of their
respective Subsidiaries is required for the preparation of the Proxy Statement
or Registration Statement, the Liberty Parties shall promptly provide such
information to United and New United upon request.

                  (b) Until consummation of the transactions contemplated by

to preserve the tax-free nature of each of the transactions contemplated by

and all Claims incident or relating to or resulting from (a) any inaccuracy in
or any breach of any representation or warranty of United or New United
contained in this Agreement or in any certificate delivered by or on behalf of
United or New United pursuant to this Agreement, (b) any nonperformance or
breach of any covenant or agreement of United or New United contained in this
Agreement or any other Transaction Document, (c) any Claim brought by a third
party against a New United Indemnified Party in respect of any untrue statement
of a material fact in the Proxy Statement or Registration Statement, or omission
to state any material fact required to be stated therein, or necessary in order
to make the statements therein, in light of the circumstances under which they
were made, not misleading, except to the extent that such untrue statement or
omission was based upon information provided by or on behalf of a Liberty Party
in writing expressly for purposes of inclusion in the Proxy Statement or
Registration Statement, and (d) all obligations and liabilities of whatever kind
and nature, primary or secondary, direct or indirect, absolute or contingent,
known or unknown, whether arising before, on or after the Closing Date arising
out of or relating to the Belmarken Loan Agreements or any Restructuring
Transaction, other than to the extent such obligation or liability arises out of
a breach of a representation, warranty, covenant or agreement of the Liberty
Parties contained in this Agreement. Subject to written notice of such claim for
indemnification being given to United within the appropriate survival period
referred to in Section 15.1, United hereby agrees to indemnify and hold New
United and its directors, officers, employees, Controlled Affiliates, agents,
successors and assigns (collectively, the "United Indemnified Parties") harmless
from and against any and all Losses resulting from, based upon, arising out of
or otherwise in respect of, and all Claims incident or relating to or

                                       75

resulting from (a) any inaccuracy in or any breach of any representation or
warranty of United contained in this Agreement or in any certificate delivered
by or on behalf of United pursuant to this Agreement, (b) any nonperformance or
breach of any covenant or agreement of United contained in this Agreement or any
other Transaction Document and (c) any Claim brought by a third party against a
United Indemnified Party in respect of any untrue statement of a material fact
in the Proxy Statement or Registration Statement, or omission to state any
material fact required to be stated therein, or necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading, except to the extent that such untrue statement or omission was
based upon information provided by or on behalf of a Liberty Party in writing
expressly for purposes of inclusion in the Proxy Statement or Registration
Statement.

         15.5 Defense of Action.

                  (a) Any Person seeking indemnification under Section 15.2,
15.3 or 15.4 (the "Indemnified Party") with respect to any third party claim,
investigation, action, suit or proceeding (collectively, an "Action") shall
promptly give notice of such Action to the party from which such indemnification
is sought (the "Indemnifying Party"). The Indemnified Party's failure to so
notify the Indemnifying Party of any Action shall not release the Indemnifying
Party, in whole or in part, from its obligations to indemnify under this
Article, except to the extent that the Indemnified Party's failure to so notify
actually prejudices the Indemnifying Party's ability to defend against such
Action. The Indemnified Party shall be entitled, at the sole expense and
liability of the Indemnifying Party, to exercise full control of the defense,
compromise or settlement of any such Action unless the Indemnifying Party,
within a reasonable time after the giving of such notice by the Indemnified
Party, shall (i) deliver a written confirmation to such Indemnified Party that
the indemnification provisions of Section 15.2, 15.3 or 15.4 (as the case may
be) are applicable to such Action and that, subject to the remaining provisions
of this Article XV, the Indemnifying Party will indemnify such Indemnified Party
in respect of such Action pursuant to the terms of Section 15.2, 15.3 or 15.4
(as the case may be), (ii) notify such Indemnified Party in writing of the
Indemnifying Party's intention to assume the defense thereof, and (iii) retain
legal counsel reasonably satisfactory to such Indemnified Party to conduct the
defense of such Action.

                  (b) The Indemnified Party and the Indemnifying Party shall
cooperate with the party assuming the defense, compromise or settlement of any
such Action in accordance herewith in any manner that such party reasonably may
request. If the Indemnifying Party so assumes the defense of any such Action,
the Indemnified Party shall have the right to employ separate counsel and to
participate in (but not control) the defense, compromise, or settlement thereof,
but the fees and expenses of such counsel shall be the expense of such
Indemnified Party unless (i) the Indemnifying Party has specifically agreed to
pay such fees and expenses, (ii) any relief other than the payment of money
damages is sought against the Indemnified Party or (iii) the Indemnified Party
shall have been advised by its counsel that there may be one or more legal
defenses available to it that are different from or additional to those
available to the Indemnifying Party or that there may be a conflict of interest
between the Indemnifying Party and the Indemnified Party in the conduct of the
defense of such Action (in either of which cases the Indemnifying Party shall
not have the right to direct the defense, compromise or settlement of

                                       76
<PAGE>

such Action on behalf of the Indemnified Party), and in any such case the
reasonable fees and expenses of such separate counsel shall be borne by the
Indemnifying Party, it being understood and agreed, however, that the
Indemnifying Party shall not be liable for the fees and expenses of more than
one separate firm of attorneys at any time for the Indemnified Party together
with its Affiliates, unless there shall be a conflict of interest between the
Indemnified Party and an Affiliate thereof, in which case the Indemnifying Party
shall not be liable for the fees and expenses of more than an aggregate of two
separate firms of attorneys at any time for the Indemnified Party and its
Affiliates. No Indemnified Party shall settle or compromise or consent to entry
of any judgment with respect to any such Action for which it is entitled to
indemnification hereunder without the prior written consent of the Indemnifying
Party, unless the Indemnifying Party shall have failed, after reasonable notice
thereof, to undertake control of such Action in the manner provided above in
this Section 15.5. The Indemnifying Party shall not, without the written consent
of the Indemnified Party, settle or compromise or consent to entry of any
judgment with respect to any such Action (x) in which any relief other than the
payment of money damages is or may be sought against any Indemnified Party, or
(y) that does not include as an unconditional term thereof the giving by the
claimant, party conducting such investigation, plaintiff or petitioner to such
Indemnified Party of a release from all liability with respect to such Action.

                  (c) If the indemnification provisions contained in this
Article XV and the indemnification provisions contained in Article XIII are both
applicable with respect to any particular matter, then the indemnification
provisions contained in Article XIII shall be controlling and shall apply for
all purposes as to such matter.

         15.6 Limitations on Indemnification for Breach of Representations and
Warranties. No indemnification by a Liberty Party or New United under Section
15.2 or 15.4 hereof in respect of an inaccuracy in or breach of any
representation or warranty in this Agreement or in any certificate delivered
pursuant hereto (other than, in each case, the Basket Exceptions, as defined
below), shall be due and payable (a) in respect of any individual claim unless
such claim equals or exceeds US $1,000,000, and (b) unless the aggregate amount
of such claims equal to or in excess of US $1,000,000 exceeds US $150,000,000
(the "Basket Amount"), whereupon the applicable Liberty Party or New United, as
the case may be, shall be obligated to pay only the excess of the aggregate
amount of such claims for indemnification over the Basket Amount. The
indemnification obligations under Sections 15.2 and 15.4 in respect of an
inaccuracy in or breach of any of the following representations or warranties
(collectively, the "Basket Exceptions") will not be subject to the limitations
of the preceding sentence: the representations and warranties in Sections 4.3,
6.1(d) and 6.2(d) ("Brokers' and Finders' Fees"); the representations and
warranties in Sections 4.5 ("Ownership of United Class B Stock"); the
representations and warranties in Sections 4.2 (fifth sentence only and only as
such sentence relates to (1) the certificates or articles of incorporation and
bylaws of the Liberty Parties and (2) Delaware Law), 6.1(c)(ii) (second sentence
only and only as such sentence relates to (1) the certificate of incorporation
and bylaws of United, (2) Delaware law and (3) any Contract evidencing or
securing any outstanding indebtedness of United or any of its Subsidiaries or
pursuant to which any such outstanding indebtedness was incurred) and 6.2(c)(ii)
("Consents and No Conflicts"); the representations and warranties in Sections
4.4, 6.1(e) and 6.2(e) ("Legal Proceedings"); the representations and warranties
in Sections 6.1(k) ("Contracts and Commitments") (last sentence only) and 6.2(j)
("Contracts; No Breach"); the representations and warranties in Section
6.1(f)(iv) ("United

                                       77
<PAGE>

A/P"); the representations and warranties in Sections 6.1(o) and 6.2(k)
("Section 203 and Similar Laws"); the representations and warranties in the
eighth sentence of Section 6.2(b)(i), that the shares of New United stock to be
issued pursuant to this Agreement and the other Transaction Documents have been
duly authorized and when issued will be validly issued, fully paid,
nonassessable and free of preemptive rights and Liens and Restrictions; the
representations and warranties in Section 6.1(j)(ix) ("Taxes"); the
representations and warranties in Section 4.7 ("Belmarken Notes"); the
representations and warranties in Section 4.11 ("Liberty UPC Bonds"); and the
representations and warranties in Sections 6.2(g)(iii) with respect to the
absence of New United liabilities. In the event of any inaccuracy in or any
breach of any representation or warranty in this Agreement or in any certificate
delivered pursuant hereto, if such representation or warranty contains a
materiality qualifier (including without limitation a reference to a Material
Adverse Effect, a Material Adverse Change, a Liberty Material Adverse Effect, a
New United Material Adverse Effect or a United Material Adverse Effect) then
such materiality qualifier shall be considered for purposes of determining
whether there has been any inaccuracy or breach subject to indemnification under
this Article XV, but such materiality qualifier shall not be considered for
purposes of determining whether any claim pursuant to this Article XV equals or
exceeds the monetary thresholds set forth in clauses (a) and (b) above.

         15.7 Insurance Proceeds. The amount that any party may be required to
pay to another party pursuant to this Article XV shall be reduced
(retroactively, if necessary) by any insurance proceeds or refunds actually
recovered by or on behalf of the applicable Indemnified Party in reduction of
the related Losses and Claims. If an Indemnified Party shall have received the
payment required by this Article XV from the Indemnifying Party in respect of
Losses and Claims and shall subsequently receive insurance proceeds in respect
of such Losses and Claims, then the Indemnified Party shall promptly repay to
the Indemnifying Party a sum equal to the amount of such insurance proceeds or
refunds actually received, net of costs and expenses, but not exceeding the
amount paid by the Indemnifying Party in respect of such Losses and Claims.

         15.8 Exclusive Monetary Remedy; No Consequential Damages. The parties
hereto hereby acknowledge and agree that their sole and exclusive remedy for
monetary damages with respect to any and all claims relating to the subject
matter of this Agreement (except damages resulting from the commission of fraud
with respect to the subject matter of this Agreement) shall be pursuant to the
indemnification provisions set forth in Articles XIII and XV; provided, however,
that nothing in this Section 15.8 shall limit in any way the availability of
specific performance, injunctive relief or other equitable remedies to which a
party may otherwise be entitled. In no event shall any party hereto be liable to
another party hereto for such other party's lost profits, lost revenues or other
indirect or consequential damages.

                                  ARTICLE XVI

                            TERMINATION OF AGREEMENT

         16.1 Termination. This Agreement may be terminated and the transactions
contemplated hereby and by the other Transaction Documents abandoned at any time
prior to the Closing (i) by the mutual written consent of United and Liberty,
(ii) by Liberty if United shall not have obtained the Exchange Ratio Fairness
Opinion and the Indenture Fairness Opinion on or before January 15, 2002, or
(iii) by either United or Liberty by giving written notice of

                                       78
<PAGE>

termination to the other if the Closing shall not have occurred on or before
February 28, 2002; provided, however, that (A) if the United Stockholders
Meeting has not been held on or before February 28, 2002, but (1) the United
Stockholders Meeting is scheduled to occur on or before March 29, 2002 and (2)
the Proxy Statement was mailed to United's Stockholders on or before February
14, 2002, then such date shall be extended to March 29, 2002, (B) if the Closing
has not occurred solely because a "Default" or "Event of Default" within the
meaning of the Indenture shall have occurred and be continuing (other than any
"Event of Default" within the meaning of Sections 6.1(a), 6.1(b), 6.1(e), 6.1(g)
or 6.1(h) of the Indenture) and, as a result of the continuance of such
"Default" or "Event of Default," the condition to closing set forth in Section
11.1 (insofar as it relates to Section 6.1(c)(ii)(z)) shall not have been
satisfied, such "Default" or "Event of Default" is of a type that is amenable to
cure without violation of the terms of this Agreement and United is, and has
been since becoming aware of such "Default" or "Event of Default," vigorously
pursuing the cure of such "Default" or "Event of Default," such date shall be
extended once to the earliest of (1) April 13, 2002 and (2) 14 days from the
date that, but for the occurrence or continuance of such "Default" or "Event of
Default," all of the conditions to Closing (except for the delivery of
consideration, instruments, certificates and opinions to be delivered at the
Closing) were or could have been satisfied, and (C) if the Closing shall not
have occurred on or before February 28, 2002 solely because an "Acceleration
Notice" has been given (and not rescinded) pursuant to Section 6.2 of the
Indenture, and as a result the condition to Closing set forth in Section 11.9
has not been satisfied, but United is vigorously contesting such Acceleration
Notice in an appropriate legal forum in good faith, then such date shall be
extended to the earliest of (1) April 29, 2002, (2) such date that United is no
longer vigorously contesting such Acceleration Notice in an appropriate legal
forum in good faith and (3) such date that such Acceleration Notice is
rescinded; provided further, however, that the right to terminate this Agreement
under clause (iii) shall not be available to United, on the one hand, or
Liberty, on the other hand, if the failure of the Closing to occur prior to such
date was a result of, in the case of United, any breach by United or any of its
Affiliates or, in the case of Liberty, any breach by any Liberty Party or any of
its Affiliates, of any of the representations, warranties, covenants or
agreements of such Person contained herein or in the other Transaction
Documents.

         16.2 Limitation of Liabilities in the Event of Termination. In the
event of any termination of this Agreement pursuant to Section 16.1, this
Agreement shall forthwith become wholly void and of no further force and effect
and there shall be no liability on the part of any of the parties hereto or
their respective Affiliates, officers or directors by reason hereof except (i)
that the provisions of Sections 2.3(a)(i) (proviso only), 7.14(b), 7.14(c),
7.14(d), this Section 16.2, Section 16.3 and Article XVII shall survive the
termination of this Agreement, and (ii) nothing herein shall relieve any party
hereto from liability for any breach by it or any of its Affiliates of any of
its or their representations, warranties, covenants or agreements made herein or
in the other Transaction Documents.

         16.3 Stockholder Arrangements. In the event of any termination of this
Agreement pursuant to Section 16.1, Liberty, United and the Founders will in
good faith negotiate agreements providing for stockholder and standstill
obligations and containing terms substantially similar to those provided for in
the forms of Stockholders Agreement and Standstill Agreement included as
exhibits to this Agreement, provided that (a) the "Maximum Percentage" or
similar provision in such agreements shall be computed in a manner consistent
with the methodology set forth in Section 7.23(c) hereof, (b) the Note Shares
and any shares of United

                                       79
<PAGE>

Class A Stock acquired by Liberty and its Controlled Affiliates in reliance on
clause (a)(iii) of the definition of "Maximum Percentage" shall not, pursuant to
such agreements, be exchangeable into shares of United Class B Stock as provided
in Section 10(a) of the Stockholders Agreement.

                                  ARTICLE XVII

                                  MISCELLANEOUS

         17.1 Expenses. Except as set forth specifically herein, each party
hereto shall pay its own expenses (including fees and expenses of legal counsel,
investment bankers, brokers or other representatives or consultants) in
connection with the transactions contemplated hereby (whether or not such
transactions are consummated). United shall pay, or cause to be paid, (a) all
filing fees in connection with any filings under the HSR Act required to be made
by Schneider or by Liberty Media or any of its subsidiaries and (b) all filing
fees and other costs and expenses of any kind whatsoever (including fees and
expenses of counsel) in connection with obtaining or making any consents,
approvals or waivers of, notices to or filings with any third parties or
Governmental Authorities that are required to be obtained or made as a result of
the Closing occurring on any date after November 30, 2001. In the event of any
proceeding to enforce this Agreement, the prevailing party shall be entitled to
receive from the losing party all reasonable costs and expenses, including the
reasonable fees of attorneys, accountants and other experts, incurred by the
prevailing party in investigating and prosecuting (or defending) such action at
trial or upon any appeal.

         17.2 Entire Agreement; Release. This Agreement (together with the
Schedules and Exhibits annexed hereto) and the other Transaction Documents
contain, and are intended as, a complete statement of all of the terms of the
agreements among the parties and their respective Affiliates with respect to the
matters provided for herein and therein, and, whether or not the Closing occurs,
supersede and discharge any previous agreements and understandings between the
parties with respect to those matters, including the Original Agreement (except
for the Disclosure Schedules provided pursuant thereto), the Letter Agreement
and the August 1999 Agreement; provided, however, that (1) the Founders'
Agreement, dated as of September 30, 1999, among certain of the Founders shall
survive the execution of the Original Agreement and the execution of this
Agreement in accordance with its terms with respect to the Founders that are
party thereto, (2) the Notes Tender Letter Agreement shall survive the execution
hereof in accordance with its terms, and (3) the letter agreement, dated
September 18, 2000, between United and Liberty Media (the "September 18 Letter
Agreement") shall survive the execution hereof in accordance with its terms,
except that (i) references therein to the "June 2000 Agreement" shall be deemed
to refer to the Letter Agreement and the reference in the third paragraph
thereof to the "Sum of the Parts" method set forth in paragraph 5 of Exhibit A
to the "June 2000 Agreement" shall instead be deemed to refer to the
Sum-of-the-Parts method described in paragraph 5 of the Letter Agreement, and
(ii) the September 18 Letter Agreement shall terminate immediately upon the
occurrence of the Closing. Each of United, on the one hand, and Liberty and LMI,
on the other hand, furthermore, hereby releases and forever discharges each
other party and their respective Affiliates of and from any and all claims,
causes of action and liabilities of any kind whatsoever, now existing or
hereafter arising, whether known or unknown, that arise out of or in any way
relate to the Letter Agreement, its inducement, its

negotiation, the negotiation of definitive documents to consummate the
transactions contemplated by it or its alleged non-performance, including,
without limitation, claims for fraud, misrepresentation, non-disclosure,
promissory estoppel, equitable estoppel, breach of express contract, breach of
implied contract or breach of the covenant of good faith and fair dealing.

         17.3 Governing Law; Waiver of Jury Trial, Etc. This Agreement shall be
governed by and construed in accordance with the laws of the State of Colorado
applied to contracts made and wholly performed in such State, without regard to
principles governing conflicts of law, except to the extent that the United/New
United Merger and the Founder Newco Mergers are necessarily governed by the laws
of the State of Delaware. Each of the parties (a) will submit itself to the
non-exclusive jurisdiction of any federal court located in the State of Colorado
or any Colorado state court having subject matter jurisdiction in the event any
dispute arises out of this Agreement, (b) agrees that venue will be proper as to
any proceeding brought in any such court with respect to such a dispute, (c)
will not attempt to deny or defeat such personal jurisdiction or venue by motion
or other request for leave from any such court and (d) WAIVES ANY RIGHT TO A
TRIAL BY JURY in any proceeding brought with respect to this Agreement or the
transactions contemplated hereby.

contained herein shall be deemed invalid or unenforceable by the laws of the
jurisdiction wherein it is to be enforced, such covenants or provisions shall be
considered divisible as to such portion and such covenants or provisions shall

provisions as are enforceable by the court or other body having jurisdiction of

amended and reformed, shall be valid and binding as though the invalid or

other Persons.

         17.11 Counterparts. This Agreement may be executed by the parties
hereto in separate counterparts, each of which when so executed and delivered
shall be an original, but all such counterparts shall together constitute one

         17.12 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 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, including the Exhibits, Disclosure Schedules and other Schedules
hereto, and not to any particular article, section or other subdivision hereof
or Exhibit, Disclosure Schedule or Schedule hereto; the phrase "made available"
means that the information referred to has been made available if requested by
the party hereto to whom such information is to be made available; any pronoun
shall include the corresponding masculine, feminine and neuter forms;

                                       83

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 any statute or regulation are to it as amended
and supplemented from time to time, and to any corresponding provisions of
successor statutes or regulations; references to "Article," "Section" or another
subdivision or to an "Exhibit" or "Schedule" are to an article, section or
subdivision hereof or an "Exhibit" or " Schedule" hereto; all references to a
"Disclosure Schedule" shall be deemed to refer to the relevant Disclosure
Schedule provided pursuant to the Original Agreement; and all references to "the
date hereof," "the date of this Agreement" or similar terms (but excluding (1)
such references as otherwise described in Articles IV, V and VI, and (2)
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. In this Agreement, except as otherwise specifically provided, any
reference to any event, change, condition or effect being "material" with
respect to any Person or group of Persons means any material event, change,
condition or effect related to the condition (financial or otherwise),
properties, assets (including intangible assets), liabilities, business,
operations, results of operations or prospects of such Person or group of
Persons. In this Agreement, any reference to a "Material Adverse Change" or
"Material Adverse Effect" with respect to any Person or group of Persons means
any event, change or effect that is materially adverse to the condition
(financial or otherwise), properties, assets, liabilities, business, operations,
results of operations or prospects of such Person and its Subsidiaries, taken as
a whole, except to the extent that such change, event or effect is attributable
to or results from (i) changes affecting the securities or capital markets or
economic conditions generally in the country or countries in which such Person
or group of Persons conduct their businesses, (ii) changes affecting the
industries in which such Person or group of Persons operate generally (as
opposed to changes affecting any such Person or group of Persons specifically or
predominantly), (iii) the effect of the public announcement of this Agreement or
the pendency of the transactions contemplated hereby and by the other
Transaction Documents, or (iv) changes in GAAP. In this Agreement, any reference
to a party's "knowledge" means such party's actual knowledge after due inquiry
of officers, directors and other key employees of such party reasonably believed
to have knowledge of such matters. Any reference herein to a "day" or number of
"days" (without the explicit qualification of "Business") shall be deemed to
refer to a calendar day or number of calendar days. If any action or notice is
to be taken or given on or by a particular calendar day, and such calendar day
is not a Business Day, then such action or notice may be taken or given on the
next succeeding Business Day.

                  17.13 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.

                  All shares of any one series of the Preferred Stock shall be

                  expressly provided in the Preferred Stock Designation for a
                  series of Preferred Stock, the holders of shares of such
                  series shall have no voting rights except as may be required
                  by the laws of the State of Delaware. Further, unless
                  otherwise expressly provided in the Preferred Stock
                  Designation for a series of Preferred Stock, no consent or

                  shares of Preferred Stock or the number of authorized shares
                  of any series thereof (but not below the number of authorized
                  shares of Preferred Stock of such series, as the case may be,
                  then outstanding). Except as may be provided by the Board of
                  Directors in a Preferred Stock Designation or by applicable
                  law, shares of any series of Preferred Stock that have been
                  redeemed (whether through the operation of a sinking fund or
                  otherwise) or purchased by the Corporation, or which, if
                  convertible or exchangeable, have been converted into or
                  exchanged for shares of stock of any other class or series
                  shall have the status of authorized and unissued shares of
                  Preferred Stock and may be reissued as a part of the series of
                  which they were originally a part or may be reissued as part
                  of a new series of Preferred Stock to be created by resolution
                  or resolutions of the Board of Directors or as part of any

                  the Corporation, whether voluntary or involuntary, after
                  payment or provision for payment of the debts and liabilities
                  of the Corporation and subject to the prior payment in full of
                  the preferential amounts to which any series of Preferred
                  Stock is entitled, the holders of shares of Common Stock of
                  all classes shall share equally, on a share for share basis,
                  in the assets of the Corporation remaining for distribution to
                  its common stockholders. Neither the consolidation or merger
                  of the Corporation with or into any other Person or Persons
                  nor the sale, transfer or lease of all or substantially all of
                  the assets of the Corporation shall itself be deemed to be a

         (a)      Classification and Election of Directors

                  (i)      The business and affairs of the Corporation shall be
                           managed by a Board of Directors. The number of
                           directors shall be fixed by the Bylaws, but shall not
                           be fewer than nine nor more than twelve. Until the
                           first meeting of the stockholders of the Corporation
                           at which directors are elected following the
                           occurrence of a Class B Event, four directors (or
                           such greater number as represents not less than
                           one-third of the total number of directors then
                           authorized, rounded upwards to the nearest whole
                           number) shall be designated as "Class C Directors"
                           and will be elected by the holders of a majority of
                           the outstanding Class C Common Stock voting as a
                           separate class. Any directors that are not designated
                           as Class C Directors shall be designated as "Regular
                           Directors" and will be elected (A) prior to the
                           occurrence of a Class B Event, by the holders of a
                           plurality of the combined voting power of the
                           outstanding Class A Common Stock and Class B Common
                           Stock, voting together as a single class and (B) from
                           and after the occurrence of a Class B Event, by the
                           holders of a plurality of the combined voting power
                           of the outstanding Class A Common Stock, Class B
                           Common Stock and Class C Common Stock, voting
                           together as a single class. All directors will be
                           designated as Regular Directors immediately prior to
                           the election of directors at the first meeting of
                           stockholders of the Corporation at which directors
                           are elected following the occurrence of a Class B
                           Event.

                  (ii)     The Regular Directors and the Class C Directors shall
                           be divided as evenly as possible into three classes,
                           designated Class I, Class II and Class III, and each
                           such class shall include at least one Class C
                           Director at all times that directors are designated
                           as Class C Directors. If the number of directors is
                           not evenly divisible by three, the remainder
                           positions shall be allocated first to Class III and
                           then to Class II. The terms of the Class I Directors
                           shall expire at the annual meeting of stockholders in
                           2003; the terms of the Class II Directors shall
                           expire at the annual meeting of stockholders in 2004;
                           and the terms of the Class III Directors shall expire
                           at the annual meeting of stockholders in 2005. At
                           each annual meeting of stockholders of the
                           Corporation, the successors of that class of
                           directors whose term expires at that meeting shall be
                           elected to hold office for a term expiring at the
                           annual meeting of stockholders of the Corporation
                           held in the third year following the year of their
                           election.

                            NEW UNITEDGLOBALCOM, INC.

                                    ARTICLE I

                                     Offices

         Section 1.01 Business Offices. The corporation may have such offices,
either within or outside Delaware, as the board of directors may from time to
time determine or as the business of the corporation may require.

         Section 1.02 Registered Office. The registered office of the
corporation required by the Delaware General Corporation Law to be maintained in
Delaware shall be as set forth in the certificate of incorporation, unless
changed as provided by law.

                                   ARTICLE II

                                  Stockholders

         Section 2.01 Annual Meeting. An annual meeting of the stockholders
shall be held on such date as may be determined by the board of directors, for
the purpose of electing directors and for the transaction of such other business
as may come before the meeting. If the day fixed for the annual meeting shall be
a legal holiday, such meeting shall be held on the next succeeding business day.
If the election of directors shall not be held on the day designated herein for
any annual meeting of the stockholders, or at any adjournment thereof, the board
of directors shall cause the election to be held at a meeting of the
stockholders as soon thereafter as conveniently may be. Failure to hold an
annual meeting as required by these bylaws shall not invalidate any action taken
by the board of directors or officers of the corporation.

         Section 2.02 Special Meetings. Special meetings of the stockholders,
for any purpose or purposes, unless otherwise prescribed by law or the
certificate of incorporation, may be called only by the board of directors
pursuant to a resolution approved by the affirmative vote of a majority of the
directors then in office, by the chairman of the board of directors or at the
request of holders of Common Stock (as defined in the certificate of
incorporation) representing a majority of the Total Voting Power (as defined in
the certificate of incorporation) of the corporation. Such resolution of the
board of directors or request by the holders of Common Stock shall state the
purpose or purposes of the proposed meeting.

<PAGE>

         Section 2.03 Place of Meeting. Each meeting of the stockholders shall
be held at such place, either within or outside Delaware, as may be designated
in the notice of meeting, or, if no place is designated in the notice, at the
principal office of the corporation.

         Section 2.04 Notice of Meetings. Except as otherwise required by law,
notice in writing or by electronic transmission of each meeting of the
stockholders stating the place, day and hour of the meeting, the means of remote
communications, if any, by which stockholders and proxy holders may be deemed to
be present in person and vote at such meeting and, in the case of a special
meeting, the purpose or purposes for which the meeting is called, shall be
given, either personally (including delivery by private courier) or by first
class, certified or registered mail, or by electronic transmission, to each
stockholder of record entitled to notice of such meeting, not less than ten nor
more than 60 days before the date of the meeting. Such notice shall be deemed to
be given, if personally delivered, when delivered to the stockholder, and, if
mailed, when deposited in the United States mail, postage prepaid, directed to
the stockholder at his address as it appears on the records of the corporation,
and if by electronic transmission, when posted on an electronic network or
directed to the stockholder at an electronic mail address at which the
stockholder has consented to receive notice. If notice of two consecutive annual
meetings and all notices of meetings to any stockholder during the period
between such two consecutive annual meetings, or all, and at least two, payments
(if sent by first class mail) of dividends or interest on securities during a
12-month period, have been mailed or directed addressed to such person at his
address as shown on the records of the corporation and have been returned
undeliverable, the giving of such notice to such person shall not be required
until another address for such person is delivered to the corporation. When a
meeting is adjourned to another time or place, notice need not be given of the
adjourned meeting if the time and place thereof are announced at the meeting at
which the adjournment is taken. At the adjourned meeting the corporation may
transact any business that might have been transacted at the original meeting.
If the adjournment is for more than 30 days, or if after the adjournment a new
record date is fixed for the adjourned meeting, notice of the adjourned meeting
shall be given to each stockholder of record entitled to vote at the meeting in
accordance with the foregoing provisions of this Section 2.04.

         Section 2.05 Fixing Date for Determination of Stockholders of Record.
For the purpose of determining stockholders entitled to notice of or to vote at
any meeting of stockholders or any adjournment thereof, or entitled to receive
payment of any dividend or other distribution or allotment of any rights, or
entitled to exercise any rights in respect of any change, conversion or exchange
of stock or for any other lawful action, the board of directors may fix, in
advance, a date as the record date for any such determination of stockholders,
which date shall be not more than 60 nor less than ten days before the date of
such meeting, and not more than 60 days prior to any other action. If no record
date is fixed then the record date shall be, for determining stockholders
entitled to notice of or to vote at a meeting of stockholders, the close of
business on the day next preceding the day on which notice is given, or, if
notice is waived, the close of business on the day next preceding the day on
which the meeting is held, or, for determining stockholders for any other
purpose, the close of business on the day on which the board of directors adopts
the resolution relating thereto. A determination of stockholders of record
entitled to notice of or to vote at a meeting of stockholders shall apply to any
adjournment of the

                                       2
<PAGE>

meeting; provided, however, that the board of directors may fix a new record
date for the adjourned meeting.

         Section 2.06 Voting List. The officer who has charge of the stock
ledger of the corporation shall prepare and make, at least ten days before every
meeting of stockholders, a complete list of the stockholders entitled to vote at
the meeting, arranged in alphabetical order, and showing the address of each
stockholder and the number of shares registered in the name of each stockholder.
Nothing contained in this Section 2.06 shall require the corporation to include
electronic mail addresses or other electronic contact information on such list.
Such list shall be open to the examination of any stockholder, for any purpose
germane to the meeting, for a period of at least ten days prior to the meeting,
either (a) on a reasonably accessible electronic network, provided that the
information required to gain access to such list is provided with the notice of
the meeting, or (b) during ordinary business hours, at a place within the city
where the meeting is to be held, which place shall be specified in the notice of
the meeting, or, if not so specified, at the place where the meeting is to be
held. In the event that the corporation determines to make the list available on
an electronic network, the corporation may take reasonable steps to ensure that
such information is available only to stockholders of the corporation. If the
meeting is to be held at a place, the list shall also be produced and kept at
the time and place of the meeting during the whole time thereof, and may be
inspected by any stockholder who is present. If the meeting is to be held solely
by means of remote communication, then the list shall also be open to the
examination of any stockholder during the whole time of the meeting on a
reasonably accessible electronic network, and the information required to access
such list shall be provided with the notice of the meeting.

         Section 2.07 Proxies. Each stockholder entitled to vote at a meeting of
stockholders may authorize another person or persons to act for him by proxy,
but no such proxy shall be voted or acted upon after three years from its date,
unless the proxy provides for a longer period.

         Section 2.08 Quorum and Manner of Acting. At all meetings of
stockholders, a majority of the combined voting power of the outstanding shares
of the corporation entitled to vote, represented in person or by proxy, shall
constitute a quorum. If a quorum is present, the affirmative vote of a majority
of the votes held by shares represented at a meeting at which a quorum is
present and entitled to vote on the subject matter shall be the act of the
stockholders, unless the vote of a greater proportion or number or voting by
classes is otherwise required by law, the certificate of incorporation or these
bylaws. In the absence of a quorum, a majority of the shares so represented may
adjourn the meeting from time to time in accordance with Section 2.04, until a
quorum shall be present or represented.

         Section 2.09 Nominations for the Election of Directors. Except as
otherwise provided in the certificate of incorporation with respect to Class C
Directors (as defined in certificate of incorporation), nominations for election
to the board of directors must be made by the board of directors or by a
committee appointed by the board of directors for such purpose or by any
stockholder of any outstanding class of capital stock of the corporation
entitled to vote for the election of directors. Except as otherwise provided in
the certificate of incorporation with respect to Class C Directors (as defined
in certificate of incorporation), nominations by stockholders must be preceded
by timely notification in writing to the secretary of the

                                       3
<PAGE>

corporation. To be timely, a stockholder's notice shall be delivered to the
secretary at the principal executive offices of the corporation not later than
the close of business on the ninetieth (90th) day nor earlier than the close of
business on the one hundred twentieth (120th) day prior to the first anniversary
of the preceding year's annual meeting; provided, however, that in the event
that the date of the annual meeting is advanced more than thirty (30) days prior
to or delayed by more than thirty (30) days after the anniversary of the
preceding year's annual meeting, notice by the stockholder to be timely must be
so delivered not earlier than the close of business on the one hundred twentieth
(120th) day prior to such annual meeting and not later than the close of
business on the later of the ninetieth (90th) day prior to such annual meeting
or the tenth (10th) day following the day on which public announcement of the
date of such meeting is first made. Such notification shall contain the written
consent of each proposed nominee to serve as a director if so elected and the
following information as to each proposed nominee and as to each person, acting
alone or in conjunction with one or more other persons as a partnership, limited
partnership, syndicate or other group, who participates or is expected to
participate in making such nomination or in organizing, directing or financing
such nomination or solicitation of proxies to vote for the nominee:

                  (a) the name, age, residence address, and business address of
each proposed nominee and of each such person;

                  (b) the principal occupation or employment, the name, type of
business and address of the corporation or other organization in which such
employment is carried on of each proposed nominee and of each such person;

                  (c) the amount of stock of the corporation owned beneficially,
either directly or indirectly, by each proposed nominee and each such person;
and

                  (d) a description of any arrangement or understanding of each
proposed nominee and of each such person with each other or any other person
regarding future employment or any future transaction to which the corporation
will or may be a party.

         The presiding officer of the meeting shall have the authority to
determine and declare to the meeting that a nomination not preceded by
notification made in accordance with the foregoing procedure shall be
disregarded.

         Section 2.10 Other Stockholder Proposals. For business other than the
nomination for election of directors to be properly brought before any meeting
by a stockholder, the stockholder must have given timely notice thereof in
writing to the secretary of the corporation. To be timely, a stockholder's
notice shall be delivered to the secretary at the principal executive offices of
the corporation not later than the close of business on the ninetieth (90th) day
nor earlier than the close of business on the one hundred twentieth (120th) day
prior to the first anniversary of the preceding year's annual meeting; provided,
however, that in the event that the date of the annual meeting is advanced more
than thirty (30) days prior to or delayed by more than thirty (30) days after
the anniversary of the preceding year's annual meeting, notice by the
stockholder to be timely must be so delivered not earlier than the close of
business on the one hundred twentieth (120th) day prior to such annual meeting
and not later than the close of business on the later of

                                       4
<PAGE>

the ninetieth (90th) day prior to such annual meeting or the tenth (10th) day
following the day on which public announcement of the date of such meeting is
first made. A stockholder's notice to the secretary shall set forth as to each
matter the stockholder proposes to bring before the meeting:

                  (a) a brief description of the business desired to be brought
before the meeting and the reasons for conducting such business at the meeting;

                  (b) the name and address, as they appear on the corporation's
books, of the stockholder proposing such business, and the name and address of
the beneficial owner, if any, on whose behalf the proposal is made;

                  (c) the class and number of shares of the corporation which
are owned beneficially and of record by such stockholder of record and by the
beneficial owner, if any, on whose behalf of the proposal is made; and

                  (d) any material interest of such stockholder of record and
the beneficial owner, if any, on whose behalf the proposal is made in such
business.

                                   ARTICLE III

                               Board of Directors

         Section 3.01 General Powers. The business and affairs of the
corporation shall be managed by or under the direction of its board of
directors, except as otherwise provided in the Delaware General Corporation Law
or the certificate of incorporation.

         Section 3.02 Number, Tenure and Qualifications. The number of directors
of the corporation shall be as set forth in the certificate of incorporation.
The board of directors shall be divided as evenly as possible into three classes
as provided in the certificate of incorporation. At each annual meeting of
stockholders, the successors of the class of directors whose term expires at
that meeting shall be elected to hold office for a term expiring at the annual
meeting of stockholders held in the third year following the year of their
election. Each director shall hold office until his successor shall have been
elected and qualified or until his earlier death, resignation or removal.
Directors need not be residents of Delaware or stockholders of the corporation.

         Section 3.03 Resignation. Any director may resign at any time by giving
notice to the corporation in writing or by electronic transmission. A director's
resignation shall take effect upon receipt or, if a different time of
effectiveness is specified therein, at the time specified therein. Unless
otherwise specified therein, the acceptance of such resignation shall not be
necessary to make it effective.

         Section 3.04 Regular Meetings. A regular meeting of the board of
directors shall be held immediately after and at the same place as the annual
meeting of stockholders, or as soon

                                       5
<PAGE>

thereafter as conveniently may be, at the time and place, either within or
without Delaware, determined by the board, for the purpose of electing officers
and for the transaction of such other business as may come before the meeting.
Failure to hold such a meeting, however, shall not invalidate any action taken
by any officer then or thereafter in office. The board of directors may provide
by resolution the time and place, either within or outside Delaware, for the
holding of additional regular meetings without other notice than such
resolution.

         Section 3.05 Special Meetings. Special meetings of the board of
directors may be called only by the chief executive officer or any member of the
board of directors. Any such special meeting may take place at any convenient
place, either within or outside Delaware.

         Section 3.06 Meetings by Telephone. Unless otherwise restricted by the
certificate of incorporation, members of the board of directors may participate
in a meeting of such board by means of conference telephone or other
communications equipment by means of which all persons participating in the
meeting can hear each other, and such participation in a meeting in such manner
shall constitute presence in person at the meeting.

         Section 3.07 Notice of Meetings. Notice of each meeting of the board of
directors (except those regular meetings for which notice is not required)
stating the place, day and hour of the meeting shall be given to each director
at least five days prior thereto by the mailing of written notice by first
class, certified or registered mail, or at least two days prior thereto by
personal delivery (including delivery by private courier) of written notice or
by telephone, telegram, telex, cablegram or other similar method, except that in
the case of a meeting to be held pursuant to Section 3.06 notice may be given by
telephone one day prior thereto. The method of notice need not be the same to
each director. Notice shall be deemed to be given when deposited in the United
States mail, with postage thereon prepaid, addressed to the director at his
business or residence address, when delivered or communicated to the director or
when the telegram, telex, cablegram or other form of notice is personally
delivered to the director or delivered to the last address of the director
furnished by him to the corporation for such purpose. Neither the business to be
transacted at nor the purpose of any meeting of the board of directors need be
specified in the notice or waiver of notice of such meeting.

         Section 3.08 Quorum and Manner of Acting. Except as otherwise may be
required by law, the certificate of incorporation (including, without
limitation, paragraph (b) of Article Fifth thereof) or these bylaws, a majority
of the number of directors fixed in accordance with these bylaws, present in
person, shall constitute a quorum for the transaction of business at any meeting
of the board of directors, and the vote of a majority of the directors present
at a meeting at which a quorum is present shall be the act of the board of
directors. If less than a quorum is present at a meeting, the directors present
may adjourn the meeting from time to time without further notice other than
announcement at the meeting, until a quorum shall be present. No director may
vote or act by proxy or power of attorney at any meeting of the board of
directors.

         Section 3.09 Action Without a Meeting. Any action required or permitted
to be taken at any meeting of the board of directors or of any committee thereof
may be taken without a meeting, without prior notice and without a vote, if all
members of the board or committee, as the case may be, consent thereto in
writing or by electronic transmission and the writing or

                                       6
<PAGE>

writings or electronic transmission or transmissions are filed with the minutes
of the proceedings of the board or committee, as the case may be.

         Section 3.10 Executive and Other Committees.

                  (a) The board of directors may designate one or more
committees, each committee to consist of one or more of the directors of the
corporation. The board may designate one or more directors as alternate members
of any committee, who may replace any absent or disqualified member at any
meeting of the committee. In the absence or disqualification of a member of a
committee, the member or members present at any meeting and not disqualified
from voting, whether or not such member or members constitute a quorum, may
unanimously appoint another member of the board of directors to act at the
meeting in the place of any such absent or disqualified member. Any such
committee, to the extent provided in the resolution of the board of directors,
shall have and may exercise all the powers and authority of the board of
directors in the management of the business and affairs of the corporation, and
may authorize the seal of the corporation to be affixed to all papers which may
require it; but no such committee shall have the power or authority in reference
to the following matters: (a) approving or adopting, or recommending to the
stockholders, any action or matter expressly required by the Delaware General
Corporation Law to be submitted to stockholders for approval or (b) adopting,
amending or repealing any bylaw of the corporation. The delegation of authority
to any committee shall not operate to relieve the board of directors or any
member of the board from any responsibility imposed by law. Subject to the
foregoing, the board of directors may provide such powers, limitations and
procedures for such committees as the board deems advisable. To the extent the
board of directors does not establish other procedures, each committee shall be
governed by the procedures set forth in Sections 3.04 (except as they relate to
an annual meeting), 3.05 through 3.09 and 7.01 and 7.02 as if the committee were
the board of directors. Each committee shall keep regular minutes of its
meetings, which shall be reported to the board of directors when required and
submitted to the secretary of the corporation for inclusion in the corporate
records.

         Section 3.11 Compensation. Unless otherwise restricted by the
certificate of incorporation, the board of directors shall have the authority to
fix the compensation of directors. The directors may be paid their expenses, if
any, of attendance at each meeting of the board of directors and each meeting of
any committee of the board of which he is a member and may be paid a fixed sum
for attendance at each such meeting or a stated salary or both a fixed sum and a
stated salary. No such payment shall preclude any director from serving the
corporation in any other capacity and receiving compensation therefor.

         Section 3.12 Certain Actions. The corporation shall not, and shall not
agree or commit to, and shall not permit any of its direct or indirect
subsidiaries to or agree or commit to, effect any transaction, or series of
related transactions, that involves (a) the issuance, delivery or payment of any
consideration (whether through the payment of cash, the issuance or delivery of
any securities, the transfer of assets or otherwise) by the corporation and any
of its direct or indirect subsidiaries having an aggregate fair market value in
excess of $10 million or (b) the incurrence, guarantee or assumption by the
corporation or any of its direct or indirect subsidiaries of any liabilities,
commitments or obligations, whether absolute, accrued, fixed,

                                       7
<PAGE>

contingent or otherwise, in an aggregate amount in excess of $10 million unless
such transaction, or series of related transactions, has first been reviewed and
approved by (x) the board of directors or (y) a committee of the board of
directors to which the board of directors has specifically delegated authority
with respect to such transaction or series of related transactions.

                                   ARTICLE IV

                                    Officers

shall consist of a chairman of the board, chief executive officer, a president,
a chief operating officer, a chief financial officer, a secretary and such other
officers, including a vice-chairman or vice-chairmen of the board, one or more
vice-presidents, a treasurer and a controller, as may from time to time be
elected or appointed by the board. In addition, the board of directors or the
chief executive officer may elect or appoint such assistant and other
subordinate officers, including assistant vice-presidents, assistant secretaries
and assistant treasurers, as it or he shall deem necessary or appropriate. Any
number of offices may be held by the same person, except that no person may
simultaneously hold the offices of president and secretary.

         Section 4.02 Election and Term of Office. Except as provided in the
certificate of incorporation and Sections 4.01 and 4.06 of these bylaws, the
officers of the corporation shall be elected by the board of directors annually
at the first meeting of the board held after each annual meeting of the
stockholders as provided in Section 3.04. If the election of officers shall not
be held as provided herein, such election shall be held as soon thereafter as
may be convenient. Each officer shall hold office until his successor shall have
been duly elected and shall have qualified or until the expiration of his term
in office if elected or appointed for a specified period of time or until his
earlier death, resignation or removal.

         Section 4.03 Compensation. Officers shall receive such compensation for
their services as may be authorized or ratified by the board of directors and no
officer shall be prevented from receiving compensation by reason of the fact
that he is also a director of the corporation. Election or appointment as an
officer shall not of itself create a contract or other right to compensation for
services performed by such officer.

         Section 4.04 Resignation. Any officer may resign at any time, subject
to any rights or obligations under any existing contracts between the officer
and the corporation, by giving notice to the corporation in writing or by
electronic transmission. An officer's resignation shall take effect upon receipt
or, if a different time of effectiveness is specified therein, at the time
stated therein. Unless otherwise specified therein, the acceptance of such
resignation shall not be necessary to make it effective.

         Section 4.05 Removal. Unless otherwise provided in the certificate of
incorporation, any officer may be removed at any time by the board of directors,
or, in the case of assistant and other subordinate officers, by the chief
executive officer, whenever in its or his judgment, as the case may be, the best
interests of the corporation will be served thereby, but such removal shall

                                       8
<PAGE>

be without prejudice to the contract rights, if any, of the person so removed.
Election or appointment of an officer shall not in itself create contract
rights.

         Section 4.06 Vacancies. Except as otherwise provided in the certificate
of incorporation, a vacancy occurring in any office by death, resignation,
removal or otherwise may be filled by the board of directors or the chief
executive officer.

                                    ARTICLE V

                                      Stock

         Section 5.01 Issuance of Shares. The issuance or sale by the
corporation of any shares of its authorized capital stock of any class,
including treasury shares, shall be made only upon authorization by the board of
directors, except as otherwise may be provided by law. Every issuance of shares
shall be recorded on the books of the corporation maintained for such purpose by
or on behalf of the corporation.

         Section 5.02 Transfer of Shares. Upon presentation and surrender to the
corporation or to a transfer agent of the corporation of a certificate of stock
duly endorsed or accompanied by proper evidence of succession, assignment or
authority to transfer, payment of all transfer taxes, if any, and the

discharge of any adverse claims of which the corporation has notice, the
corporation or the transfer agent shall issue a new certificate to the person
entitled thereto, cancel the old certificate and record the transaction on the
books maintained for such purpose by or on behalf of the corporation. No
transfer of shares shall be effective until it has been entered on such books.
The corporation or a transfer agent of the corporation may require a signature

effective before making any transfer. Transfers of uncertificated shares shall
be made in accordance with applicable provisions of law.

         Section 5.03 Registered Holders. The corporation shall be entitled to

duties and shall be entitled to such compensation as may be agreed.

                                   ARTICLE VI

                                 Indemnification

         Section 6.01 Directors and Officers. The corporation shall indemnify
its directors and officers to the fullest extent not prohibited by the Delaware
General Corporation Law or any other applicable law; provided, however, that the
corporation may modify the extent of such indemnification by individual
contracts with its directors and officers; and, provided, further, that the
corporation shall not be required to indemnify any director or officer in
connection with any proceeding (or part thereof) initiated by such person unless
(i) such indemnification is expressly

                                       11
<PAGE>

required to be made by law, (ii) the proceeding was authorized by the Board of
Directors of the corporation, (iii) such indemnification is provided by the
corporation, in its sole discretion, pursuant to the powers vested in the
corporation under the Delaware General Corporation Law or any other applicable
law or (iv) such indemnification is required to be made under Section 6.04.

         Section 6.02 Employees and Other Agents. The corporation shall have
power to indemnify its employees and other agents as set forth in the Delaware
General Corporation Law or any other applicable law. The Board of Directors
shall have the power to delegate the determination of whether indemnification
shall be given to any such person to such officers or other persons as the Board
of Directors shall determine.

         Section 6.03 Expenses.

                  (a) The corporation shall advance to any person who was or is
a party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative, by reason of the fact that he is or was a director or officer of
the corporation, or is or was serving at the request of the corporation as a
director or officer of another corporation, partnership, joint venture, trust or
other enterprise, prior to the final disposition of the proceeding, promptly
following request therefor, all expenses incurred by any director or officer in
connection with such proceeding upon receipt of an undertaking by or on behalf
of such person to repay said amounts if it should be determined ultimately that
such person is not entitled to be indemnified under this Article VI or
otherwise.

                  (b) Notwithstanding the foregoing, unless otherwise determined
pursuant to Section 6.05, no advance shall be made by the corporation to an
officer of the corporation (except by reason of the fact that such officer is or
was a director of the corporation, in which event this paragraph shall not
apply) in any action, suit or proceeding, whether civil, criminal,
administrative or investigative, if a determination is reasonably and promptly
made (i) by the Board of Directors by a majority vote of a quorum consisting of
directors who were not parties to the proceeding, or (ii) if such quorum is not
obtainable, or, even if obtainable, a quorum of disinterested directors so
directs, by independent legal counsel in a written opinion, that the facts known
to the decision-making party at the time such determination is made demonstrate
clearly and convincingly that such person acted in bad faith or in a manner that
such person did not believe to be in or not opposed to the best interests of the
corporation.

         Section 6.04 Enforcement. Without the necessity of entering into an
express contract, all rights to indemnification and advances to directors and
officers under this Article VI shall be deemed to be contractual rights and be
effective to the same extent and as if provided for in a contract between the
corporation and the director or officer. Any right to indemnification or
advances granted by this Article VI to a director or officer shall be
enforceable by or on behalf of the person holding such right in any court of
competent jurisdiction if (i) the claim for indemnification or advances is
denied, in whole or in part, or (ii) no disposition of such claim is made within
ninety (90) days of request therefor. The claimant in such enforcement action,
if successful in whole or in part, shall be entitled to be paid also the expense
of prosecuting his claim. In connection with any claim for indemnification, the
corporation shall be entitled to raise as a defense to any such action that the
claimant has not met the standards of conduct that make

                                       12
<PAGE>

it permissible under the Delaware General Corporation Law or any other
applicable law for the corporation to indemnify the claimant for the amount
claimed. In connection with any claim by an officer of the corporation (except
in any action, suit or proceeding, whether civil, criminal, administrative or
investigative, by reason of the fact that such officer is or was a director of
the corporation) for advances, the corporation shall be entitled to raise a
defense as to any such action clear and convincing evidence that such person
acted in bad faith or in a manner that such person did not believe to be in or
not opposed to the best interests of the corporation, or with respect to any
criminal action or proceeding that such person acted without reasonable cause to
believe that his conduct was lawful. Neither the failure of the corporation
(including its Board of Directors, independent legal counsel or its
stockholders) to have made a determination prior to the commencement of such
action that indemnification of the claimant is proper in the circumstances
because he has met the applicable standard of conduct set forth in the Delaware
General Corporation Law or any other applicable law, nor an actual determination
by the corporation (including its Board of Directors, independent legal counsel
or its stockholders) that the claimant has not met such applicable standard of
conduct, shall be a defense to the action or create a presumption that claimant
has not met the applicable standard of conduct. In any suit brought by a
director or officer to enforce a right to indemnification or to an advancement
of expenses hereunder, the burden of proving that the director or officer is not
entitled to be indemnified, or to such advancement of expenses, under this
Article VI or otherwise shall be on the corporation.

         Section 6.05 Non-Exclusivity of Rights. The rights conferred on any
person by this Article VI shall not be exclusive of any other right which such
person may have or hereafter acquire under any applicable statute, provision of
the certificate of incorporation, bylaws, agreement, vote of stockholders or
disinterested directors or otherwise, both as to action in his official capacity
and as to action in another capacity while holding office. The corporation is
specifically authorized to enter into individual contracts with any or all of
its directors, officers, employees or agents respecting indemnification and
advances, to the fullest extent not prohibited by the Delaware General
Corporation Law or any other applicable law.

         Section 6.06 Survival of Rights. The rights conferred on any person by
this Article VI shall continue as to a person who has ceased to be a director,
officer, employee or other agent and shall inure to the benefit of the heirs,
executors and administrators of such a person.

         Section 6.07 Insurance. To the fullest extent permitted by the Delaware
General Corporation Law, or any other applicable law, the corporation, upon
approval by the Board of Directors, may purchase insurance on behalf of any
person required or permitted to be indemnified pursuant to this Article VI.

         Section 6.08 Amendments. Any repeal or modification of this Article VI
shall only be prospective and shall not affect the rights under this Article VI
in effect at the time of the alleged occurrence of any action or omission to act
that is the cause of any proceeding against any agent of the corporation.

         Section 6.09 Severability. If this Article VI or any portion hereof
shall be invalidated on any ground by any court of competent jurisdiction, then
the corporation shall nevertheless

                                       13
<PAGE>

indemnify each director and officer to the full extent not prohibited by any
applicable portion of this Article VI that shall not have been invalidated, or
by any other applicable law. If this Article VI shall be invalid due to the
application of the indemnification provisions of another jurisdiction, then the
corporation shall indemnify each director and officer to the full extent under
applicable law.

         Section 6.10 Certain Definitions. For the purposes of this Article VI,
the following definitions shall apply:

                  (a) The term "proceeding" shall be broadly construed and shall
include, without limitation, the investigation, preparation, prosecution,
defense, settlement, arbitration and appeal of, and the giving of testimony in,
any threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative.

                  (b) The term "expenses" shall be broadly construed and shall
include, without limitation, court costs, attorneys' fees, witness fees, fines,
amounts paid in settlement or judgment and any other costs and expenses of any
nature or kind incurred in connection with any proceeding.

                  (c) The term "corporation" shall include, in addition to the
resulting corporation, any constituent corporation (including any constituent of
a constituent) absorbed in a consolidation or merger which, if its separate
existence had continued, would have had power and authority to indemnify its
directors, officers, and employees or agents, so that any person who is or was a
director, officer, employee or agent of such constituent corporation, or is or
was serving at the request of such constituent corporation as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise, shall stand in the same position under the provisions
of this Article VI with respect to the resulting or surviving corporation as he
would have with respect to such constituent corporation if its separate
existence had continued.

                  (d) References to a "director," "executive officer,"
"officer," "employee," or "agent" of the corporation shall include, without
limitation, situations where such person is serving at the request of the
corporation as, respectively, a director, executive officer, officer, employee,
trustee or agent of another corporation, partnership, joint venture, trust or
other enterprise.

                  (e) References to "other enterprises" shall include employee
benefit plans; references to "fines" shall include any excise taxes assessed on
a person with respect to an employee benefit plan; and references to "serving at
the request of the corporation" shall include any service as a director,
officer, employee or agent of the corporation which imposes duties on, or
involves services by, such director, officer, employee, or agent with respect to
an employee benefit plan, its participants, or beneficiaries; and a person who
acted in good faith and in a manner he reasonably believed to be in the interest
of the participants and beneficiaries of an employee benefit plan shall be
deemed to have acted in a manner "not opposed to the best interests of the
corporation" as referred to in this Article VI.

                                  Miscellaneous

         Section 7.01 Waivers of Notice. Whenever notice is required to be given
by law, by the certificate of incorporation or by these bylaws, a written waiver
thereof, signed by the person entitled to said notice or a waiver by electronic
transmission by the person entitled to notice, whether before or after the time
stated therein, shall be deemed equivalent to notice. Attendance of a person at
a meeting or (in the case of a stockholder) by proxy shall constitute a waiver
of notice of such meeting, except when the person attends a meeting for the
express purpose of objecting, at the beginning of the meeting, to the
transaction of any business because the meeting was not lawfully called or
convened. Neither the business to be transacted at, nor the purpose of, any
meeting need be specified in any written waiver of notice or waiver of notice by
electronic transmission unless required by these bylaws to be included in the
notice of such meeting.

         Section 7.02 Presumption of Assent. A director or stockholder of the
corporation who is present at a meeting of the board of directors or
stockholders at which action on any corporate matter is taken shall be presumed
to have assented to the action taken unless his dissent shall be entered in the
minutes of the meeting or unless he shall file his written dissent to such
action with the person acting as the secretary of the meeting before the
adjournment thereof or shall forward such dissent by registered mail to the
secretary of the corporation immediately after the adjournment of the meeting.
Such right to dissent shall not apply to a director or stockholder who voted in
favor of such action.

         Section 7.03 Voting of Securities by the Corporation. Unless otherwise
provided by resolution of the board of directors, on behalf of the corporation
the chairman of the board, chief executive officer, chief operating officer,
chief financial officer, president, secretary, treasurer or any vice-president
shall attend in person or by substitute appointed by him, or shall execute
written instruments appointing a proxy or proxies to represent the corporation
at, all meetings of the stockholders of any other corporation, association or
other entity in which the corporation holds any stock or other securities, and
may execute written waivers of notice with respect to any such meetings. At all
such meetings and otherwise, the chairman of the board, chief executive officer,
chief operating officer, chief financial officer, president, secretary,
treasurer or any vice-president, in person or by substitute or proxy as
aforesaid, may vote the stock or other securities so held by the corporation and
may execute written consents and any other instruments with respect to such
stock or securities and may exercise any and all rights and powers incident to
the ownership of said stock or securities, subject, however, to the
instructions, if any, of the board of directors.

         Section 7.04 Seal. The corporate seal of the corporation shall be in
such form as adopted by the board of directors, and any officer of the
corporation may, when and as required, affix or impress the seal, or a facsimile
thereof, to or on any instrument or document of the corporation.

                                       15

         Section 7.05 Fiscal Year. The fiscal year of the corporation shall be
as established by the board of directors.

                             SUBSCRIPTION AGREEMENT

UnitedGlobalCom, Inc.
4643 South Ulster Street, Suite 1300
Denver, Colorado 80237

Ladies and Gentlemen:

         1. Subscription. The undersigned, [___________] (the "Purchaser"),
intending to be legally bound, hereby purchases from UnitedGlobalCom, Inc. (the
"Company"), and the Company hereby sells to the Purchaser, [______] shares of
the Series E Convertible Preferred Stock, par value $0.01 per share, of the
Company (the "Preferred Stock") for an aggregate purchase price of
[__________](1) (the "Purchase Price") payable (i) in cash or (ii) in cash at
least to the extent of the aggregate par value of the Preferred Stock, and the
remainder by delivery of a promissory note made by the Purchaser payable to the
Company with a principal amount equal to the Purchase Price less the aggregate
par value of the Preferred Stock (a "Promissory Note"). Any Promissory Note
delivered in payment of any portion of the Purchase Price shall provide for full
recourse to the Purchaser in the event of the nonpayment thereof, shall provide
for the accrual of interest at a fair market rate and contain other terms and
conditions consistent with an arm's-length, fair market transaction, all of
which terms shall be reasonably acceptable to Liberty Media Corporation
("Liberty Media").

         The Preferred Stock is convertible into shares of Class A Common Stock,
par value $0.01 per share (the "Class A Stock" and, together with the Preferred
Stock, the "Securities"), of the Company on the terms and conditions set forth
in the Certificate of Designation establishing the Preferred Stock (the
"Certificate of Designation").

         2. Deliveries. Concurrently with the execution and delivery hereof, (a)
the Purchaser is delivering the Purchase Price to the Company by wire transfer
of immediately available funds in accordance with instructions from the Company
and, if applicable, by delivery of a Promissory Note and (b) the Company is
delivering to the Purchaser a certificate, in the name of the Purchaser and duly
executed by appropriate officers of the Company, representing the Preferred
Stock purchased hereby.

         3. Representations and Warranties of the Purchaser. The Purchaser
hereby acknowledges, represents, warrants and agrees as follows:

--------
(1) The per share purchase price of the Series E Preferred Stock will be equal
to 1/1,500th of the product (rounded up to the nearest cent) of (a) the lesser
of (1) $5.00 and (2) the Average Market Price of the United Class A Stock as of
the Closing Date, multiplied by (b) a number equal to (1) the quotient of X
divided by Y minus (2) X. For purposes of the foregoing, "X" shall be equal to
the aggregate number of shares of United Class A Stock and United Class B Stock
issued and outstanding immediately prior to the Closing and "Y" shall be equal
to 0.995049505.

<PAGE>

                  (a) None of the Securities have been registered under the
Securities Act of 1933, as amended (the "Securities Act"), or any state
securities laws. The Purchaser understands that the offering and sale of the
Securities is intended to be exempt from registration under the Securities Act
by virtue of Section 4(2) thereof, and analogous provisions of state securities
laws, based, in part, upon the representations, warranties and agreements
contained in this Subscription Agreement.

                  (b) The Purchaser has received copies of the Certificate of
Designation, the SEC Filings (as defined below) and all other documents
requested by the Purchaser, has carefully reviewed such documents in their
entirety and understands the information contained therein. For purposes of this
Subscription Agreement, "SEC Filings" shall mean the Company's: (i) preliminary
proxy statement filed with the Securities and Exchange Commission ("SEC") on
January 25, 2001; (ii) registration statement filed with the SEC on [________],
(iv) Form 10-K for the year ended December 31, 2000; (iv) Forms 10-Q filed with
the SEC for the quarters ended March 31, 2001, June 30, 2001 and September 30,
2001; and (v) Form 8-K filed with the SEC on June 1, 2001.

                  (c) Neither the SEC nor any state securities commission has
passed upon or endorsed the merits of this offering of Securities or made any
findings or determination as to the fairness of the terms of this offering for
investment.

                  (d) In evaluating the suitability of an investment in the
Company, the Purchaser has not relied upon any representation or other
information (oral or written) by or from the Company other than as stated in the
Certificate of Designation and the SEC Filings.

                  (e) The Purchaser has taken no action that would give rise to
any claim by any person for brokerage commissions, finders' fees or the like
relating to this Subscription Agreement or the transactions contemplated hereby.

                  (f) The Purchaser, together with his attorneys, accountants,
purchaser representatives and tax advisors (collectively, the "Advisors"), has
such knowledge and experience in financial, tax, and business matters so as to
enable him to utilize the information made available to him in connection with
the offering of the Securities to evaluate the merits and risks of an investment
in the Securities and to make an informed investment decision with respect
thereto.

                  (g) The Purchaser is not relying on information provided by
the Company with respect to the financial, tax and other economic considerations
of an investment in the Securities, and in such regard the Purchaser has relied
on the advice of, and has consulted with, only his own Advisors.

                  (h) The Purchaser is acquiring the Securities solely for his
own account for investment and not with a view to resale or distribution
thereof.

                  (i) The Purchaser acknowledges that he must bear the economic
risk of an investment in the Securities indefinitely because none of the
Securities may be sold,

                                       2
<PAGE>

hypothecated or otherwise disposed of unless subsequently registered under the
Securities Act and applicable state securities laws or an exemption from
registration is available. In addition, Section 8 of this Subscription Agreement
imposes certain further restrictions on the transfer of the Preferred Stock.
Legends shall be placed on the certificates evidencing the Securities to the
effect that such Securities have not been registered under the Securities Act or
applicable state securities laws and that such Securities are subject to certain
restrictions on transfer imposed by this Subscription Agreement, and appropriate
notations to such effect will be made in the Company's stock transfer books.

                  (j) The Purchaser has adequate means of providing for his
current needs and foreseeable personal contingencies and has no need for his
investment in the Securities to be liquid.

                  (k) The Purchaser is aware that an investment in the
Securities involves significant risks.

                  (l) The Purchaser is an "accredited investor," within the
meaning of Rule 501(a) of Regulation D under the Securities Act ("Regulation
D"), because (i) he is a natural person who has a net worth or joint net worth
with his spouse in excess of $1,000,000 as of the date hereof; (ii) he is a
natural person who had an individual income in excess of $200,000 in each of the
two most recent calendar years [or a joint income with his spouse in excess of
$300,000 in each of those years] and has a reasonable expectation of reaching
the same income level in the current year; and (iii) he is a director and an
executive officer of the Company. As used in this Subscription Agreement, the
term "net worth" means the excess of total assets over total liabilities.(2)

                  (m) The Purchaser has had the opportunity to obtain any
additional information necessary to verify the accuracy of the SEC Filings and
all other documents received or reviewed by him in connection with the purchase
of the Securities and has had the opportunity to meet with representatives of
the Company and to have them answer any questions and provide additional
information regarding the terms and conditions of this particular investment and
the finances, operations, business and prospects of the Company deemed relevant
by the Purchaser and all such questions have been answered and requested
information provided to his full satisfaction.

                  (n) The Purchaser represents to the Company that the
information contained herein is complete and accurate and understands that such
information is being relied upon by the Company in determining the availability
of an exemption from registration under Federal and State securities laws in
connection with the offering and sale of the Securities. The Purchaser further
represents and warrants that he will notify the Company immediately upon the
occurrence of any material change therein occurring prior to the Company's
issuance of any Securities.

----------
(2) This representation is subject to change depending upon whether the
Purchaser is a natural person or a business entity and, with respect to the
bracketed portion, the state of the Purchaser's residence.

                                       3
<PAGE>

                  (o) The Purchaser has significant prior investment experience,
including investment in non-listed and non-registered securities. The Purchaser
has a sufficient net worth to sustain a loss of his entire investment in the
Securities if such a loss should occur. The Purchaser's overall commitment to
investments that are not readily marketable is not excessive in view of his net
worth and financial circumstances and the purchase of the Securities will not
cause such commitment to become excessive. The investment is a suitable one for
the Purchaser.

                  (p) If the Purchaser is paying a portion of the Purchase Price
by delivery of a Promissory Note, the Purchaser has, and shall maintain at all
times until such time that the Purchaser's obligations under the Promissory Note
are satisfied in full, unencumbered assets (other than the Securities) having an
aggregate value sufficient for the repayment of the Purchaser's obligations
under the Promissory Note

         4. Representations and Warranties of the Company. The Company hereby
represents and warrants to the Purchaser as follows:

                  (a) The Company is duly incorporated, validly existing and in
good standing under the laws of its state of incorporation.

                  (b) The Company has duly authorized by all requisite corporate
action the issuance and sale of the Preferred Stock in accordance with the terms
of this Subscription Agreement and the issuance of the Class A Stock upon
conversion of the Preferred Stock in accordance with the Certificate of
Designation.

         5. Indemnification. The Purchaser agrees to indemnify and hold harmless
the Company, its officers, directors, employees, agents, control persons and
affiliates against all losses, liabilities, claims, damages, and expenses
(including, but not limited to, any and all expenses incurred in investigating,
preparing, or defending against any litigation commenced or threatened) by
reason of or arising out of any actual or alleged false representation or
misrepresentation or warranty or breach or omission to state a material fact by
the Purchaser of any agreement herein or in any other document delivered in
connection with this Subscription Agreement.

         6. Binding Effect. The Purchaser hereby acknowledges and agrees that
this Subscription Agreement shall survive the death or disability of the
Purchaser and shall be binding upon and inure to the benefit of the parties and
their heirs, executors, administrators, successors, legal representatives, and
permitted assigns.

         7. Notices. Any notice or other communication required or permitted to
be given hereunder shall be in writing and shall be mailed by certified mail,
return receipt requested, or personally delivered to the party to whom it is to
be given (a) if to Company, at the address set forth above, or (b) if to the
Purchaser, at the address set forth on the signature page hereof (or, in either
case, to such other address as the party shall have furnished in writing in

address which shall be deemed given at the time of receipt thereof. Any notice
or other communication personally delivered shall be deemed given at the time of
such personal delivery.

         8. Assignability; Transfer Restrictions. This Subscription Agreement
and the rights, interests and obligations hereunder are not transferable or
assignable by the Purchaser. The Purchaser further agrees that he shall not, (a)
offer, transfer, pledge, encumber, contract to do any of the foregoing or
otherwise transfer or dispose of, whether or not for or without consideration
("Transfer"), directly or indirectly, any of the Securities to any person or
other entity whatsoever except in accordance with all applicable laws, including
Federal and State securities laws, or (b) Transfer, directly or indirectly, any
shares of Preferred Stock to any person or other entity whatsoever without the
prior written consent of Liberty Media, and that any purported Transfer in
violation of (a) or (b) shall be null and void.

         9. Applicable Law. This Subscription Agreement shall be governed by and
construed in accordance with the internal laws of the State of Colorado without
regard to its conflicts of law principles. The Purchaser hereby irrevocably
submits to the jurisdiction of any Colorado State or United States Federal court
sitting in the City and County of Denver over any action or proceeding arising
out of or relating to this Subscription Agreement or any agreement contemplated
hereby, and the Purchaser hereby irrevocably agrees that all claims in respect

party against whom enforcement of such modification, waiver or consent is
sought.

                  (b) The Purchaser's representations and warranties made in
this Subscription Agreement shall survive the execution and delivery hereof and

the Company's receipt of a written request (the "Request") from all Purchasers
holding Registrable Notes that the Company effect the registration under the
Securities Act of all such Registrable Notes (the date of such receipt being the
"Request Date"), the Company will use commercially reasonable efforts to (a)
prepare and, as soon as practicable but not later than 60 days following the
Request Date, file with the SEC a Shelf Registration Statement on an appropriate
form under the 1933 Act covering resales of the Registrable Notes, which shall
include a plan of distribution requested by the Purchasers holding all of the

effective in order to permit the Prospectus forming part thereof to be usable by
the Named Purchasers for a period of 180 days following the date on which the
Shelf Registration Statement becomes effective, or for such shorter period that
will terminate when all Registrable Notes covered by the Shelf Registration
Statement have been sold pursuant to the Shelf Registration Statement, exchanged
or redeemed in accordance with their terms or otherwise cease to be outstanding
or become saleable pursuant to Rule 144(k) under the 1933 Act (the
"Effectiveness Period"), and (d) notwithstanding any other provisions hereof,
ensure that (i) the Shelf Registration Statement and any amendment thereto and
any Prospectus forming part thereof and any supplement thereto complies in all
material respects with the 1933 Act and the rules and regulations thereunder,
(ii) the Shelf Registration Statement and any amendment thereto does not, when
it becomes effective, contain an untrue statement of a material fact or omit to
state a material fact required to be stated therein

                                       3
<PAGE>

or necessary to make the statements therein not misleading and (iii) any
Prospectus forming part of the Shelf Registration Statement, and any supplement
to such Prospectus (as amended or supplemented from time to time), does not
include an untrue statement of a material fact or omit to state a material fact
necessary in order to make the statements, in light of the circumstances under
which they were made, not misleading. Notwithstanding the foregoing, if during
the Effectiveness Period, the Company is unable to file with the SEC, or have
reviewed or declared effective, a Shelf Registration Statement due to the
application of Rule 3-01(c) of Regulation S-X (a "Blackout Period"), then the
applicable Effectiveness Period shall be extended (A) in the case of the Company
being unable to file (or the SEC advising the Company that it will not review
the Shelf Registration Statement until financial statements for the most recent
fiscal year of the Company are included in the filing), for a period equal to
the Blackout Period plus 45 calendar days and (B) in the case of the Company's
having filed a Shelf Registration Statement (and not having been informed by the
SEC to the effect set forth in the preceding parenthetical) but being unable to
have it declared effective, for a period equal to the Blackout Period plus ten
calendar days. Notwithstanding the foregoing, in no event shall an Effectiveness
Period exceed a period of 270 calendar days.

         The Company shall not permit any securities other than Registrable
Notes to be included in the Shelf Registration Statement. The Company further
agrees, if necessary, to supplement or amend the Shelf Registration Statement
and the Prospectus, as required by Section 3(b) below, and to furnish to the
Named Purchasers copies of any such supplement or amendment as promptly as
reasonably practicable after filing with the SEC.

         2.2 Expenses. The Company shall pay all Registration Expenses in
connection with the registration pursuant to Section 2.1 hereof. In addition to
such Registration Expenses, if a Named Purchaser incurs any underwriting
expenses, discounts, commissions, transfer taxes or other selling costs, if any,
relating to the sale or disposition of such Named Purchaser's Registrable Notes
pursuant to the Shelf Registration Statement, the Company shall reimburse such
Named Purchaser for any such expenses incurred in an amount not to exceed 0.50%
of the aggregate principal amount of the Registrable Notes sold or disposed of
in such transaction.

         2.3 Effectiveness. (a) The Company will be deemed not to have used
commercially reasonable efforts to cause the Shelf Registration Statement to
become, or to remain, effective during the requisite period if the Company
voluntarily takes any action that would, or omits to take any action which
omission would, result in any Shelf Registration Statement not being declared
effective or in the Named Purchasers covered thereby not being able to offer and
sell their Registrable Notes during that period as and to the extent
contemplated hereby, unless (i) such action is required by applicable law, or
(ii) such action is taken by the Company in good faith and for valid business
reasons (not including avoidance of the Company's obligations hereunder),
including the acquisition or divestiture of assets, so long as the Company
promptly thereafter complies with the requirements of Section 3(j) hereof, if
applicable.

         Notwithstanding anything to the contrary contained herein, if at any
time after the filing or effectiveness of a Shelf Registration Statement the
Company determines, in its reasonable business judgment, that such registration
and the offering of Registrable Notes pursuant thereto could interfere with or
otherwise adversely affect any financing, acquisition, corporate reorganization,
or other material transaction or development involving the Company, or require

                                       4
<PAGE>

the Company to disclose matters that otherwise would not be required to be
disclosed at such time, then the Company may require the suspension by Named
Purchasers, for a period of up to 45 calendar days (during which time the
Effectiveness Period, if applicable, will be suspended and which time the
Effectiveness Period will resume and will be extended for a period equal to such
suspension period), of the distribution of any of the Registrable Notes pursuant
to such Shelf Registration Statement by giving written notice to the Named
Purchasers. Any such notice need not specify the reasons for such suspension if
the Company determines, in its reasonable business judgment, that doing so would
interfere with or adversely affect such transaction or development or would
result in the disclosure of material non-public information to such Named
Purchasers. Any such suspension shall continue until the earlier to occur of the
expiration of such 45-calendar-day period and the determination of the Company,
notice of which is given to the Named Purchasers, that such registration and
offering would no longer have an effect described in the first sentence of this
paragraph. The Company may not require the suspension by Named Purchasers of the
distribution of Registrable Notes pursuant to this paragraph more than twice.

         (b) A Shelf Registration Statement will not be deemed to have become
effective unless it has been declared effective by the SEC; provided, however,
that if, after it has been declared effective, the offering of Registrable Notes
pursuant to a Shelf Registration Statement is interfered with by any stop order,
injunction or other order or requirement of the SEC or any other governmental
agency or court, the Shelf Registration Statement will be deemed not to have
become effective during the period of such interference, until the offering of
Registrable Notes pursuant to the Shelf Registration Statement may legally
resume.

         3. Registration Procedures.

         In connection with the obligations of the Company with respect to the
Shelf Registration Statement, the Company shall:

                  (a) prepare and file with the SEC a Shelf Registration

rules and regulations thereunder applicable to them with respect to the
disposition of all Registrable Notes covered by the Shelf Registration Statement

including financial statements and schedules and, if the Named Purchaser so
requests, all exhibits in order to facilitate the public sale or other
disposition of the Registrable Notes; and (iii) hereby consent to the use of the
Prospectus or any amendment or supplement thereto by each of the Named
Purchasers in connection with the offering and sale of the Registrable Notes
covered by the Prospectus or any amendment or supplement thereto;

                  (d) use commercially reasonable efforts to register or qualify
the Registrable Notes under all applicable state securities or "blue sky" laws
of such jurisdictions as any Named Purchaser and each underwriter of an
underwritten offering of Registrable Notes shall reasonably request by the time

and all other acts and things which may be reasonably necessary or advisable to
enable each such Named Purchaser and underwriter to consummate the disposition
in each such jurisdiction of the Registrable Notes owned by such Named
Purchaser; provided, however, that the Company shall not be required to (i)
qualify as a foreign corporation or as a dealer in securities in any
jurisdiction where it would not otherwise be required to qualify but for this
Section 3(d), (ii) take any action which would subject it to general service of
process or taxation in any such jurisdiction where it is not then so subject, or
(iii) conform its capitalization or the composition of its assets at the time to

Company contained in any underwriting agreement, securities sales agreement or
other similar agreement, if any, relating to the offering cease to be true and
correct in all material respects, (v) of the happening of any event or the
discovery of any facts during the period the Shelf Registration Statement is

the related Prospectus untrue in any material respect or which requires the
making of any changes in the Shelf Registration Statement or Prospectus in order
to make the statements therein not misleading, (vi) of the receipt by the
Company of any notification with respect to the suspension of the qualification

the Company that a post-effective amendment to the Shelf Registration Statement
would be appropriate;

                  (f) furnish to a single counsel for the Named Purchasers

statements and schedules (without documents incorporated therein by reference
and all exhibits thereto, unless requested);

                  (i) facilitate the timely preparation, and delivery to DTC (if
permissible under DTC's rules) of, a global certificate representing the
Registrable Notes that are available for sell under the Shelf Registration
Statement, which certificate shall not bear any restrictive legends, and
simultaneously with the delivery of such certificate, cause the cancellation of
the certificates representing Registrable Notes delivered to the Purchasers on
the Closing Date;

                  (j) upon the occurrence of any event or the discovery of any
facts, such as contemplated by Sections 3(e)(v) and 3(e)(vii) hereof, as
promptly as practicable after the occurrence of such an event, use commercially
reasonable efforts to prepare a supplement or post-effective amendment to the
Shelf Registration Statement or the related Prospectus or any document
incorporated therein by reference or file any other required document so that,
as thereafter delivered to the purchasers of the Registrable Notes, such
Prospectus will not contain at the time of such delivery any untrue statement of
a material fact or omit to state a material fact necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading. At such time as such public disclosure is otherwise made or the
Company determines that such disclosure is not necessary, in each case to
correct any misstatement of a material fact or to include any omitted material

forms and documents required to be filed with the SEC to enable the Indenture to

         business acquired by the Company for which financial statements are, or
         are required to be, included in the Shelf Registration Statement)
         addressed to the underwriters, such letters to be in customary form and
         covering matters of the type customarily covered in "cold comfort"

                  (v) if an underwriting agreement is entered into, cause the
         same to set forth indemnification provisions and procedures
         substantially equivalent to the indemnification provisions and
         procedures set forth in Section 4 hereof with respect to the
         underwriters and all other parties to be indemnified pursuant to said
         Section or, at the request of any underwriters, in the form customarily
         provided to such underwriters in similar types of transactions; and

                  (vi) deliver such documents and certificates as may be
         reasonably requested and as are customarily delivered in similar
         offerings to the Named Purchasers and the managing underwriters, if
         any.

The above shall be done at (i) the effectiveness of the Shelf Registration
Statement (and each post-effective amendment thereto) and (ii) each closing
under any underwriting or similar agreement as and to the extent required
thereunder;

                                       8
<PAGE>

                  (n) at least ten Business Days prior to filing the Shelf
Registration Statement or any amendment to the Shelf Registration Statement or
the Prospectus or any supplement to the Prospectus, provide copies of such
document to the Named Purchasers and their counsel and to the underwriter or
underwriters of an underwritten offering of Registrable Notes, if any, make such
changes in any such document prior to the filing thereof as the Named Purchasers
or their counsel or the underwriter or underwriters reasonably request and not
file any such document in a form to which the Named Purchasers or their counsel
or any underwriter shall not have previously been advised and furnished a copy
of or to which the Named Purchasers or their counsel or any underwriter shall
reasonably object, and make the representatives of the Company available for
discussion of such document as shall be reasonably requested by the Named
Purchasers or their counsel or any underwriter; provided, however, that the
rights of each Named Purchaser pursuant to this Section 3(n) shall survive only
for so long as such Named Purchaser holds any principal amount of Registrable
Notes;

                  (o) otherwise comply with all applicable rules and regulations
of the SEC and make available to its security holders, as soon as reasonably
practicable, an earnings statement covering at least 12 months which shall
satisfy the provisions of Section 11(a) of the 1933 Act and Rule 158 thereunder;
and

                  (p) cooperate and assist in any filings required to be made
with the National Association of Securities Dealers, Inc. and in the performance
of any customary due diligence investigation by any underwriter and its counsel.

         The Company may (as a condition to any Purchaser's participation in the
Shelf Registration) require each Purchaser to furnish to the Company such
information regarding itself and the proposed distribution by it of its
Registrable Notes as the Company may from time to time reasonably request in
writing for use in connection with the Shelf Registration Statement or
Prospectus included therein, including without limitation, information specified
in Item 507 of Regulation S-K under the 1933 Act.

         Each Named Purchaser agrees that, upon receipt of any notice from the
Company of the happening of any event or the discovery of any facts, each of the
kind described in Section 3(e)(v) hereof, such Named Purchaser will forthwith
discontinue disposition of Registrable Notes pursuant to the Shelf Registration
Statement until such Named Purchaser's receipt of the copies of the supplemented
or amended Prospectus contemplated by Section 3(j) hereof, and, if so directed
by the Company, such Named Purchaser will deliver to the Company (at its
expense) all copies in such Named Purchaser's possession, other than permanent
file copies then in such Named Purchaser's possession, of the Prospectus
covering such Registrable Notes current at the time of receipt of such notice.

         If any of the Registrable Notes covered by any Shelf Registration
Statement are to be sold in an underwritten offering, the underwriter or
underwriters and manager or managers that will manage such offering will be
selected by the Named Purchasers, provided such selection is reasonably
acceptable to the Company. No Named Purchaser may participate in any
underwritten registration hereunder unless such Named Purchaser (a) agrees to
sell its Registrable Notes on the basis provided in any underwriting
arrangements approved by the Persons entitled hereunder to approve such
arrangements, and (b) completes and executes all

                                       9
<PAGE>

questionnaires, powers of attorney, indemnities, underwriting agreements and
other documents required under the terms of such underwriting arrangements.

         4. Indemnification; Contribution.

                  (a) The Company agrees to indemnify and hold harmless each
Named Purchaser, each Person who participates as an underwriter (any such Person
being an "Underwriter"), each of the respective directors and officers of each
of the foregoing, and each Person, if any, who controls any Named Purchaser or
Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of
the 1934 Act as follows:

                  (i) against any and all loss, liability, claim, damage and
         expense, as incurred, arising out of any untrue statement or alleged
         untrue statement of a material fact contained in the Shelf Registration
         Statement (or any amendment or supplement thereto) pursuant to which
         Registrable Notes were registered under the 1933 Act, including all
         documents incorporated therein by reference, or the omission or alleged
         omission therefrom of a material fact required to be stated therein or
         necessary to make the statements therein not misleading, or arising out
         of any untrue statement or alleged untrue statement of a material fact
         contained in any Prospectus (or any amendment or supplement thereto) or
         the omission or alleged omission therefrom of a material fact necessary
         in order to make the statements therein, in the light of the
         circumstances under which they were made, not misleading;

                  (ii) against any and all loss, liability, claim, damage and
         expense, as incurred, to the extent of the aggregate amount paid in
         settlement of any litigation, or any investigation or proceeding by any
         governmental agency or body, commenced or threatened, or of any claim
         based upon any such untrue statement or omission, or any such alleged
         untrue statement or omission; provided that (subject to Section 4(d)
         below) any such settlement is effected with the written consent of the
         Company; and

                  (iii) against any and all expense, as incurred (including the
         fees and disbursements of counsel chosen by any indemnified party as
         provided herein), reasonably incurred in investigating or defending
         against any litigation, or any investigation or proceeding by any
         governmental agency or body, commenced or threatened, or any claim
         based upon any such untrue statement or omission, or any such alleged
         untrue statement or omission, to the extent that any such expense is
         not paid under subparagraph (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss,
liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Company by or
on behalf of a Named Purchaser or Underwriter expressly for use in the Shelf
Registration Statement (or any amendment thereto) or any Prospectus (or any
amendment or supplement thereto), and provided further, that the Company shall
not indemnify any Underwriter or any Person who controls such Underwriter from
any loss, liability, claim or damage (or expense incurred in connection
therewith) alleged by any Person who purchased Registrable Notes from such
Underwriter if the untrue statement, omission or allegation thereof

                                       10
<PAGE>

upon which such loss, liability, claim or damage is based was made in (i) any
preliminary prospectus, if a copy of the Prospectus (as then amended or
supplemented if the Company shall have furnished any amendments or supplements
thereto) was not sent or given by or on behalf of such Underwriter to such
Person at or prior to the written confirmation of the sale of Registrable Notes
to such Person, and if the Prospectus (as so amended or supplemented) corrected
the untrue statement or omission giving rise to such loss, claim, damage or
liability; (ii) any Prospectus used by such Underwriter or any Person who
controls such Underwriter, after such time as the Company advised the
Underwriters that the filing of a post-effective amendment or supplement thereto
was required, except the Prospectus as so amended or supplemented, if the
Prospectus as amended or supplemented by such post-effective amendment or
supplement would not have given rise to such loss, liability, claim or damage;
or (iii) any Prospectus used after such time as the obligation of the Company to
keep the same current and effective has expired.

                  (b) Each Named Purchaser severally, but not jointly, agrees to
indemnify and hold harmless the Company, any other Named Purchaser, each
Underwriter, if any, and each of their respective directors and officers, and
each Person, if any, who controls the Company, such other Named Purchaser or
Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of
the 1934 Act, against any and all loss, liability, claim, damage and expense
described in the indemnity contained in Section 4(a) hereof, as incurred, but
only with respect to untrue statements or omissions, or alleged untrue
statements or omissions, made in the Shelf Registration Statement (or any
amendment thereto) or any Prospectus included therein (or any amendment or
supplement thereto) in reliance upon and in conformity with written information
with respect to such Named Purchaser furnished to the Company by or on behalf of
such Named Purchaser expressly for use in the Shelf Registration Statement (or
any amendment thereto) or such Prospectus (or any amendment or supplement
thereto); provided, however, that no such Named Purchaser shall be liable for
any claims hereunder in excess of the amount of net proceeds received by such
Named Purchaser from the sale of Registrable Notes pursuant to the Shelf
Registration Statement.

                  (c) Each indemnified party shall give written notice as
promptly as reasonably practicable to each indemnifying party of any action or
proceeding commenced against it in respect of which indemnity may be sought
hereunder, and the indemnifying party shall assume the defense thereof,
including the employment of counsel satisfactory to the indemnified party, and
the payment of all expenses. Any omission to so notify an indemnifying party
shall not relieve such indemnifying party from any liability hereunder to the
extent it is not materially prejudiced as a result thereof and in any event
shall not relieve it from any liability which it may have otherwise than on
account of this indemnity agreement. Any such indemnified party shall have the
right to employ separate counsel in any such action or proceeding and to
participate in the defense thereof, but the fees and expenses of such separate
counsel shall be paid by such indemnified party unless (i) the indemnifying
party has agreed to pay such fees and expenses or (ii) the indemnifying party
shall have failed to assume the defense of such action or proceeding and employ
counsel reasonably satisfactory to the indemnified party in any such action or
proceeding or (iii) the named parties to any such action or proceeding
(including any impleaded parties) include both such indemnified party and
indemnifying party, and the indemnified party shall have been advised by its
counsel that there may be a conflict of interest between such indemnified party
and indemnifying party in the conduct of the defense of such action (in which
case, if such indemnified party notifies the indemnifying party in writing that
it elects to employ

                                       11
<PAGE>

separate counsel at the expense of the indemnifying party, the indemnifying
party shall not have the right to assume the defense of such action or
proceeding on behalf of such indemnified party), it being understood, however,
that the indemnifying party shall not, in connection with any one such action or
proceeding or separate but substantially similar or related actions or
proceedings arising out of the same general allegations or circumstances, be
liable for the reasonable fees and expenses of more than one separate firm of
attorneys (unless the members of such firm are not admitted to practice in a
jurisdiction where an action is pending, in which case the indemnifying party
shall pay the reasonable fees and expenses of one additional firm of attorneys
to act as local counsel in such jurisdiction, provided the services of such
counsel are substantially limited to that of appearing as attorneys of record)
at any time for all indemnified parties, which firm shall be designated in
writing by the indemnified party. No indemnifying party shall, without the prior
written consent of the indemnified parties, settle or compromise or consent to
the entry of any judgment with respect to any litigation, or any investigation
or proceeding by any governmental agency or body, commenced or threatened, or
any claim whatsoever in respect of which indemnification or contribution could
be sought under this Section 4 (whether or not the indemnified parties are
actual or potential parties thereto), unless such settlement, compromise or
consent (A) includes an unconditional release of each indemnified party from all
liability arising out of such litigation, investigation, proceeding or claim and
(B) does not include a statement as to or an admission of fault, culpability or
a failure to act by or on behalf of any indemnified party.

                  (d) If at any time an indemnified party shall have requested
an indemnifying party to reimburse the indemnified party for fees and expenses
of counsel, such indemnifying party agrees that it shall be liable for any
settlement of the nature contemplated by Section 4(a)(ii) hereof effected
without its written consent if (i) such settlement is entered into more than 45
days after receipt by such indemnifying party of the aforesaid request, (ii)
such indemnifying party shall have received notice of the terms of such
settlement at least 30 days prior to such settlement being entered into, and
(iii) such indemnifying party shall not have reimbursed such indemnified party
in accordance with such request prior to the date of such settlement.

                  (e) If the indemnification provided for in this Section 4 is
for any reason unavailable to hold harmless an indemnified party (other than by
reason of the first sentence of Section 4(c) hereof) in respect of any losses,
liabilities, claims, damages or expenses referred to therein, then each
indemnifying party shall contribute to the aggregate amount of such losses,
liabilities, claims, damages and expenses incurred by such indemnified party, as
incurred, in such proportion as is appropriate to reflect the relative fault of
the Company on the one hand and the Named Purchasers on the other hand in
connection with the statements or omissions which resulted in such losses,
liabilities, claims, damages or expenses, as well as any other relevant
equitable considerations.

         The relative fault of the Company on the one hand and the Named
Purchasers on the other hand shall be determined by reference to, among other
things, whether any such untrue or alleged untrue statement of a material fact
or omission or alleged omission to state a material fact relates to information
supplied by or on behalf of the Company or the Named Purchasers and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.

                                       12
<PAGE>

         The Company and the Purchasers agree that it would not be just and
equitable if contribution pursuant to this Section 4 were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to above in this Section 4. The aggregate
amount of losses, liabilities, claims, damages and expenses incurred by an
indemnified party and referred to above in this Section 4 shall be deemed to
include any legal or other expenses reasonably incurred by such indemnified
party in investigating, preparing or defending against any litigation, or any
investigation or proceeding by any governmental agency or body, commenced or
threatened, or any claim whatsoever based upon any such untrue or alleged untrue
statement or omission or alleged omission.

         No Person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the 1933 Act) shall be entitled to contribution from any Person
who was not guilty of such fraudulent misrepresentation.

         For purposes of this Section 4, each Person, if any, who controls a
Named Purchaser within the meaning of Section 15 of the 1933 Act or Section 20
of the 1934 Act shall have the same rights to contribution as such Named
Purchaser, and each Person, if any, who controls the Company within the meaning
of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same
rights to contribution as the Company.

         5. Miscellaneous.

         5.1 Rule 144 and Rule 144A. For so long as the Company is subject to
the reporting requirements of Section 13 or 15 of the 1934 Act, the Company
covenants that it will file the reports required to be filed by it under the
1933 Act and Section 13(a) or 15(d) of the 1934 Act and the rules and
regulations adopted by the SEC thereunder. If the Company ceases to be so
required to file such reports, the Company covenants that it will upon the
request of any Purchaser deliver to a prospective purchaser such information as
is necessary to permit sales pursuant to Rule 144A under the 1933 Act to the
extent required from time to time to enable such Purchaser to sell its Notes
without registration under the 1933 Act within the limitation of the exemptions
provided by (i) Rule 144 under the 1933 Act, as such Rule may be amended from
time to time, (ii) Rule 144A under the 1933 Act, as such Rule may be amended
from time to time, or (iii) any similar rules or regulations hereafter adopted
by the SEC. Upon the request of any Purchaser, the Company will deliver to such
Purchaser a written statement as to whether it has complied with such
requirements. The Company's obligations under this Section 5.1 shall terminate
upon the consummation of the Effectiveness Period.

         5.2 Regulation M. Each Purchaser covenants with the Company that, with
respect to any Notes owned or held by such Purchaser that such Purchaser
continues to own or hold at any time on or after the 90th day following the
effective date of the Shelf Registration Statement, such Purchaser will, upon
receipt of written notice from the Company of the Company's intention to bid for
or purchase any Note or any security of the same class and series as the Notes
(within the meaning of Regulation M promulgated by the SEC (or any successor or
equivalent rule or regulation, "Regulation M")) or to take any other action,
directly or indirectly, the taking of which would be proscribed by Regulation M
during a distribution of the Notes, such Purchaser will, and will cause its
"affiliated purchasers" (as defined in Rule 100 of Regulation M) to, cease
distributing the Notes for such period of time as the Company may reasonably
deem

                                       13
<PAGE>

necessary so that the action or actions proposed to be taken, directly or
indirectly, by it may be taken in full compliance with Regulation M.

         5.3 No Inconsistent Agreements. The Company has not entered into and
the Company will not after the date of this Agreement enter into any agreement
which is inconsistent with the rights granted to the Purchasers under this
Agreement or otherwise conflicts with the provisions hereof. The rights granted
to the Purchasers hereunder do not and will not for the term of this Agreement
in any way conflict with the rights granted to the holders of the Company's
other issued and outstanding securities under any such agreements.

         5.4 Amendments and Waivers. The provisions of this Agreement, including
the provisions of this sentence, may not be amended, modified or supplemented,
and waivers or consents to departures from the provisions hereof may not be
given unless the Company has obtained the written consent of the Purchasers.

         5.5 Notices. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand delivery, registered
first-class mail, telecopier, or any courier guaranteeing overnight delivery (a)
if to a Purchaser, at the most current address given by such Purchaser to the
Company by means of a notice given in accordance with the provisions of this
Section 5.5, which address initially is the address set forth in the Merger
Agreement with respect to UGC; and (b) if to the Company, initially at the
Company's address set forth in the Merger Agreement, and thereafter at such
other address of which notice is given in accordance with the provisions of this
Section 5.5.

         All such notices and communications shall be deemed to have been duly
given: at the time delivered by hand, if personally delivered; two Business Days
after being deposited in the mail, postage prepaid, if mailed; when receipt is
acknowledged, if telecopied; and on the next Business Day if timely delivered to
an air courier guaranteeing overnight delivery.

         Copies of all such notices, demands, or other communications shall be
concurrently delivered by the Person giving the same to the Trustee under the
Indenture, at the address specified in such Indenture.

         5.6 Assignment; Successor and Assigns. Each Purchaser may assign its
rights and obligations under this Agreement only to a Subsidiary of such
Purchaser (any such Subsidiary, a "Permitted Assignee") to whom such Purchaser
has transferred its Notes. This Agreement shall inure to the benefit of and be
binding upon (a) the successors and assigns of the Company and (b) the Permitted
Assignees of the Purchasers; provided that nothing in this Section 5.6 shall be
deemed to permit any assignment, transfer or other disposition of Notes in
violation of the terms of this Agreement, the Merger Agreement or the Indenture.
If any Permitted Assignee shall acquire Notes, in any manner, whether by
operation of law or otherwise, such Notes shall be held subject to all of the
terms of this Agreement, and by taking and holding such Notes such Permitted
Assignee shall be conclusively deemed to have agreed to be bound by and to
perform all of the terms and provisions of this Agreement, including the
restrictions on resale set forth in this Agreement and, if applicable, the
Merger Agreement, and such Permitted Assignee shall be entitled to receive the
benefits hereof, in each case as if such Permitted Assignee were a

                                       14
<PAGE>

"Purchaser" hereunder. Any transferee of Notes that is not a Subsidiary of a
Purchaser shall not be entitled to the benefits of this Agreement.

         5.7 Specific Enforcement. Without limiting the remedies available to
the Purchasers, the Company acknowledges that any failure by the Company to
comply with its obligations under Sections 2.1 through 2.3 hereof may result in
material irreparable injury to the Purchasers for which there is no adequate
remedy at law, that it would not be possible to measure damages for such
injuries precisely and that, in the event of any such failure, the Purchasers
may obtain such relief as may be required to specifically enforce the Company's
obligations under Sections 2.1 through 2.3 hereof.

         5.8 Counterparts. This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

         5.9 Headings. The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

         5.10 GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK WITHOUT REGARD TO THE
PRINCIPLES OF CONFLICT OF LAWS THEREOF.

         5.11 Severability. In the event that any one or more of the provisions
contained herein, or the application thereof in any circumstance, is held
invalid, illegal or unenforceable, the validity, legality and enforceability of
any such provision in every other respect and of the remaining provisions
contained herein shall not be affected or impaired thereby.

                                       15

         IN WITNESS WHEREOF, the parties have executed this Agreement as of the

                                       OF
                             UNITEDGLOBALCOM, INC.

     FIRST: The name of the corporation (the "Corporation") is:

                               UGC Holdings, Inc.

     SECOND: The address of the Corporation's registered office in the State of
Delaware is 1209 Orange Street in the City of Wilmington, County of New Castle.
The name of the Corporation's registered agent at that address is The
Corporation Trust Company.

     THIRD: The purpose of the Corporation is to engage in any lawful act or
activity for which a corporation may be organized under the General Corporation
Law of the State of Delaware.

     FOURTH: (a) Authorized Shares.

        The total number of shares of capital stock that the Corporation shall
        have authority to issue is 1,156,031 which shall be divided into the
        following classes:

        (i)  1,500 shares shall be of a class designated Class A Common Stock,
           par value $0.01 per share ("Class A Common Stock");

        (ii) 1,500 shares shall be of a class designated Class B Common Stock,
           par value $0.01 per share ("Class B Common Stock"); and

        (iii) 301,500 shares shall be of a class designated Class C Common
           Stock, par value $0.01 per share ("Class C Common Stock" and,
           together with the Class A Common Stock and the Class B Common Stock,
           the "Common Stock"); and

        (iv) 851,531 shall be of a class designated Preferred Stock, par value

        Each share of Class A Common Stock, Class B Common Stock and Class C
        Common Stock shall be identical in all respects except as otherwise set
        forth in this Certificate of Incorporation (as it may from time to time
        hereafter be amended or restated, this "Certificate"). The number of
        authorized shares of Class A Common Stock, Class B Common Stock or Class
        C Common Stock may be increased or decreased (but not below the number
        of shares thereof outstanding and, in the case of the Class C Common
        Stock, the number reserved for issuance upon conversion of the Class A
        Common Stock) by an amendment to this Certificate approved by the
        affirmative vote of the holders of a majority of the combined voting
        power of the Class A Common Stock, Class B Common Stock and Class C
        Common Stock, voting together as a single class and without separate

        entire board of directors shall be equal to eight, (ii) four directors
        will be elected by the holders of a plurality of the Class A Common
        Stock (the "Class A Directors"), and (iii) four directors will be
        elected by the holders of a plurality of the Class B Common Stock (the
        "Class B Directors"). The Class C Common Stock will not vote in the
        election of directors. From and after such time as no Class A Common
        Stock is outstanding, the directors shall no longer be classified as
        "Class A Directors" and "Class B Directors," and all of the directors
        shall be elected by the holders of a majority of the Class B Common
        Stock.

     (b) Term of Office; Vacancies.

        A director shall hold office until his or her successor shall be elected

        to the office of a Class A Director, however caused, shall be filled by
        a majority of the Class A Directors then in office or by a sole
        remaining Class A Director. Any vacancy with respect to the office of a
        Class B Director, however caused, shall be filled by a majority of the
        Class B Directors then in office or by a sole remaining Class B
        Director. From and after such time as no shares of Class A Common Stock
        are outstanding, any newly created directorship resulting from an
        increase in the number of directors or any other vacancy with respect to
        the office of a director, however caused, shall be filled by a majority
        of the directors then in office or by a sole remaining director. Any
        director elected as provided above by one or more directors to fill a
        newly created directorship or other vacancy shall, without regard to the
        class in which the vacancy occurred, hold office until the next
        succeeding annual meeting of stockholders and until his or her successor

        directors constituting the Board of Directors shall shorten the term of
        any incumbent director.

     (c) Removal.

        Any or all of the Class A Directors may be removed from the Board of
        Directors with or without cause only upon the affirmative vote of the
        holders of at least 66 2/3 percent of the combined voting power of the

        without cause, upon the affirmative vote of the holders of a majority of
        the combined voting power of the Class B Common Stock, voting as a
        separate class. From and after such time as no Class A Common Stock is
        outstanding, any or all of the directors may be removed from the Board
        of Directors, with or without cause, upon the affirmative vote of the
        holders of a majority of the Class B Common Stock, voting as a separate
        class.

     (d) Required Vote.

        taken by the Board of Directors may be taken only upon the affirmative
        vote or consent in writing of (i) a majority of all directors then in
        office, (ii) a majority of the Class A Directors then in office and
        (iii) a majority of the Class B Directors then in office. From and after
        such time as no Class A Common Stock is outstanding, any action to be
        taken by the Board of Directors may be taken only upon the affirmative
        vote of a majority of the directors then in office.

     (a) Right to Indemnification.

        party or is otherwise involved in any action, suit or proceeding,
        whether civil, criminal, administrative or investigative (a

        required to indemnify or make advances to a Person in connection with a
        proceeding (or part thereof) initiated by such Person only if the

        the Corporation.

     (b) Prepayment of Expenses.

        The Corporation shall pay the expenses (including attorneys' fees)
        incurred by a director or officer in defending any proceeding in advance
        of its final disposition, provided, however, that the payment of
        expenses incurred by a director or officer in advance of the final
        disposition of the proceeding shall be made only upon receipt of an
        undertaking by the director or officer to repay all amounts advanced if
        it should be ultimately determined that the director or officer is not
        entitled to be indemnified under this Article Seventh or otherwise.

     (c) Claims.

        If a claim for indemnification or payment of expenses under this Article
        Seventh is not paid in full within 60 days after a written claim
        therefor has been received by the Corporation, the claimant may file
        suit to recover the unpaid amount of such claim and, if successful in
        whole or in part, shall be entitled to be paid the expense of
        prosecuting such claim. In any such action the Corporation shall have
        the burden of proving that the claimant was not entitled to the
        requested indemnification or payment of expenses under applicable law.

     (d) Non-Exclusivity of Rights.

        The rights conferred on any Person by this Article Seventh shall not be
        exclusive of any other rights that such Person may have or hereafter
        acquire under any statute, provision of this Certificate, the Bylaws,
        agreement, vote of stockholders or resolution of disinterested directors
        or otherwise.

     (e) Other Indemnification.

        The Corporation's obligation, if any, to indemnify any person who was or
        is serving at its request as a director, officer, employee or agent of
        another corporation, partnership, joint venture, trust, enterprise or
        nonprofit entity shall be reduced by any amount such person may collect
        as indemnification from such other corporation, partnership, joint
        venture, trust, enterprise or nonprofit entity.

     EIGHTH: Any action that may be taken at any annual or special meeting of
the stockholders may be taken without a meeting, without prior notice and
without a vote, if a consent or consents in writing, setting forth the action so
taken, shall be signed by the holders of outstanding stock having not less than
the minimum number of votes that would be necessary to authorize or take such
action at a meeting at which all shares entitled to vote thereon were present
and voted and shall be delivered to the Secretary of the Corporation.

                                   ARTICLE II

                                  STOCKHOLDERS

SECTION 2.01  Annual Meeting.  An annual meeting of the stockholders shall be
held on such date as may be determined by the board of directors, for the
purpose of electing directors and for the transaction of such other business as
may come before the meeting. If the day fixed for the annual meeting shall be a
legal holiday, such meeting shall be held on the next succeeding business day.
If the election of directors shall not be held on the day designated herein for
any annual meeting of the stockholders, or at any adjournment thereof, the board
of directors shall cause the election to be held at a meeting of the
stockholders as soon thereafter as conveniently may be. Failure to hold an
annual meeting as required by these bylaws shall not invalidate any action taken
by the board of directors or officers of the corporation.

SECTION 2.02  Special Meetings.  Except as otherwise required by law or in the
certificate of incorporation, special meetings of the stockholders, for any
purpose or purposes, unless otherwise prescribed by statute, may be called only
by the board of directors pursuant to a resolution approved by the affirmative
vote of a majority of directors then in office, by the chairman of the board of
directors, or at the request of holders of a majority of the Class A Common
Stock, Class B Common Stock and Class C Common Stock (as each such term is
defined in the certificate of incorporation), voting together as a single class.
Such request shall state the purpose or purposes of the proposed meeting.

SECTION 2.03  Place of Meeting.  Each meeting of the stockholders shall be held
at such place, either within or outside Delaware, as may be designated in the
notice of meeting, or, if no place is designated in the notice, at the principal
office of the corporation.

SECTION 2.04  Notice of Meetings.  Except as otherwise required by law, notice
in writing or by electronic transmission of each meeting of the stockholders
stating the place, day and hour of the meeting, the means of remote
communications, if any, by which stockholders and proxy holders may be deemed to
be present in person and vote at such meeting and, in the case of a special
meeting, the purpose or purposes for which the meeting is called, shall be
given, either personally (including delivery by private courier) or by first
class, certified or registered mail, or by electronic transmission, to each
stockholder of record entitled to notice of such meeting, not less than ten nor
more than 60 days before the date of the meeting. Such notice shall be deemed to
be given, if personally delivered, when delivered to the stockholder, and, if
mailed, when deposited in the United States mail, postage prepaid, directed to
the stockholder at his address as it appears on the records of the corporation,
and if by electronic transmission, when posted on an electronic network or
directed to the stockholder at an electronic mail address at which the
stockholder has consented to receive notice. If notice of two consecutive annual
meetings and all notices of meetings or the taking of action by written consent
without a meeting to any stockholder during the period between such two
consecutive annual meetings, or all, and at least two, payments (if sent by

                                       1
<PAGE>

first class mail) of dividends or interest on securities during a 12-month
period, have been mailed or directed addressed to such person at his address as
shown on the records of the corporation and have been returned undeliverable,
the giving of such notice to such person shall not be required until another
address for such person is delivered to the corporation. When a meeting is
adjourned to another time or place, notice need not be given of the adjourned
meeting if the time and place thereof are announced at the meeting at which the
adjournment is taken. At the adjourned meeting the corporation may transact any
business that might have been transacted at the original meeting. If the
adjournment is for more than 30 days, or if after the adjournment a new record
date is fixed for the adjourned meeting, notice of the adjourned meeting shall
be given to each stockholder of record entitled to vote at the meeting in
accordance with the foregoing provisions of this Section 2.04.

SECTION 2.05  Fixing Date for Determination of Stockholders of Record.  For the
purpose of determining stockholders entitled to notice of or to vote at any
meeting of stockholders or any adjournment thereof, or entitled to receive
payment of any dividend or other distribution or allotment of any rights, or
entitled to exercise any rights in respect of any change, conversion or exchange
of stock or for any other lawful action, the board of directors may fix, in
advance, a date as the record date for any such determination of stockholders,
which date shall be not more than 60 nor less than ten days before the date of
such meeting, and not more than 60 days prior to any other action. If no record
date is fixed then the record date shall be, for determining stockholders
entitled to notice of or to vote at a meeting of stockholders, the close of
business on the day next preceding the day on which notice is given, or, if
notice is waived, the close of business on the day next preceding the day on
which the meeting is held, or, for determining stockholders for any other
purpose, the close of business on the day on which the board of directors adopts
the resolution relating thereto. A determination of stockholders of record
entitled to notice of or to vote at a meeting of stockholders shall apply to any
adjournment of the meeting; provided, however, that the board of directors may
fix a new record date for the adjourned meeting. Notwithstanding the foregoing
provisions of this Section 2.05, the record date for determining stockholders
entitled to take, or receive notice of, corporate action in writing without a
meeting as provided in Section 2.11 shall be determined as provided in such
Section.

SECTION 2.06  Voting List.  The officer who has charge of the stock ledger of
the corporation shall prepare and make, at least ten days before every meeting
of stockholders, a complete list of the stockholders entitled to vote at the
meeting, arranged in alphabetical order, and showing the address of each
stockholder and the number of shares registered in the name of each stockholder.
Nothing contained in this Section 2.06 shall require the corporation to include
electronic mail addresses or other electronic contact information on such list.
Such list shall be open to the examination of any stockholder, for any purpose
germane to the meeting, for a period of at least ten days prior to the meeting,
either (a) on a reasonably accessible electronic network, provided that the
information required to gain access to such list is provided with the notice of
the meeting, or (b) during ordinary business hours, at a place within the city
where the meeting is to be held, which place shall be specified in the notice of
the meeting, or, if not so specified, at the place where the meeting is to be
held. In the event that the corporation determines to make the list available on
an electronic network, the corporation may take reasonable steps to ensure that
such information is available only to stockholders of the corporation. If the
meeting is to be held at a place, the list shall also be produced and kept at
the time and place of the meeting during the whole time thereof, and may be
inspected by any stockholder who is present. If the meeting is to be held solely
by means of remote communication, then the list shall also be open to the
examination of any stockholder during the whole time of the meeting on a
reasonably accessible electronic network, and the information required to access
such list shall be provided with the notice of the meeting.

SECTION 2.07  Proxies.  Each stockholder entitled to vote at a meeting of
stockholders or to express consent or dissent to corporate action in writing
without a meeting may authorize another person or persons to act for him by
proxy, but no such proxy shall be voted or acted upon after three years from its
date, unless the proxy provides for a longer period.

SECTION 2.08  Quorum and Manner of Acting.  At all meetings of stockholders, a
majority of the combined voting power of the outstanding shares of the
corporation entitled to vote, represented in person

                                       2
<PAGE>

or by proxy, shall constitute a quorum. If a quorum is present, the affirmative
vote of a majority of the shares represented at a meeting at which a quorum is
present and entitled to vote on the subject matter shall be the act of the
stockholders, unless the vote of a greater proportion or number or voting by
classes is otherwise required by law, the certificate of incorporation or these
bylaws. In the absence of a quorum, a majority of the shares so represented may
adjourn the meeting from time to time in accordance with Section 2.04, until a
quorum shall be present or represented.

SECTION 2.09  Action Without a Meeting.

     (a)  Written Consent.  Unless otherwise provided in the certificate of
     incorporation, any action required or permitted to be taken at any meeting
     of the stockholders may be taken without a meeting, without prior notice
     and without a vote, if a consent in writing, setting forth the action so
     taken, shall be signed by the holders of outstanding stock having not less
     than the minimum number of votes that would be necessary to authorize or
     take such action at a meeting at which all shares entitled to vote thereon
     were present and voted (which consent may be signed in counterparts). Every
     written consent shall bear the date of signature of each stockholder who
     signs the consent and no written consent shall be effective to take the
     corporate action referred to therein unless, within 60 days of the earliest
     dated consent delivered to the corporation in the manner required by the
     Delaware General Corporation Law, written consents signed by a sufficient
     number of stockholders to take the action are delivered to the corporation
     in the manner required by the Delaware General Corporation Law.

     (b)  Determination of Stockholders Entitled to Act By Consent.  For
     purposes of determining stockholders entitled to consent to corporate
     action in writing without a meeting, the board of directors may fix, in
     advance, a date as the record date for any such determination of
     stockholders, which date shall be not more than ten days after the date
     upon which the resolution fixing the record date is adopted by the board of
     directors. If no record date has been fixed by the board of directors, the
     record date for determining stockholders entitled to consent to corporate
     action in writing without a meeting, when no prior action by the board of
     directors is required by the Delaware General Corporation Law, shall be the
     first date on which a signed written consent setting forth the action taken
     or proposed to be taken is delivered to the corporation in the manner
     required by the Delaware General Corporation Law. If no record date has
     been fixed by the board of directors and prior action by the board of
     directors is required by the Delaware General Corporation Law, the record
     date for determining stockholders entitled to consent to corporate action
     in writing without a meeting shall be the close of business on the day on
     which the board of directors adopts the resolution taking such prior
     action.

     (c)  Notice to Non-Consenting Stockholders.  Prompt written notice of the
     taking of corporate action without a meeting by less than unanimous written
     consent shall be given to those stockholders who have not consented in
     writing. Such notice shall be given in accordance with the applicable
     provisions of Section 2.04.

                                  ARTICLE III

                               BOARD OF DIRECTORS

SECTION 3.01  General Powers.  The business and affairs of the corporation shall
be managed by or under the direction of its board of directors, except as
otherwise provided in the Delaware General Corporation Law or the certificate of
incorporation.

SECTION 3.02  Number, Tenure and Qualifications.  Except as otherwise provided
in the certificate of incorporation, the number of directors of the corporation
and the manner of electing such directors shall be as set forth from time to
time in a resolution of the board of directors. Directors shall be elected at
each annual meeting of stockholders. Each director shall hold office until his
successor shall have been elected and qualified or until his earlier death,
resignation or removal. Directors need not be residents of Delaware or
stockholders of the corporation.

                                       3

SECTION 3.03  Resignation.  Any director may resign at any time by giving notice
to the corporation in writing or by electronic transmission. A director's
resignation shall take effect upon receipt or, if a different time of
effectiveness is specified therein, at the time specified therein. Unless
otherwise specified therein, the acceptance of such resignation shall not be
necessary to make it effective.

SECTION 3.04  Regular Meetings.  A regular meeting of the board of directors
shall be held immediately after and at the same place as the annual meeting of
stockholders, or as soon thereafter as conveniently may be, at the time and
place, either within or without Delaware, determined by the board, for the
purpose of electing officers and for the transaction of such other business as
may come before the meeting. Failure to hold such a meeting, however, shall not
invalidate any action taken by any officer then or thereafter in office. The
board of directors may provide by resolution the time and place, either within
or outside Delaware, for the holding of additional regular meetings without
other notice than such resolution.

SECTION 3.05  Special Meetings.  Special meetings of the board of directors may
be called only by the board of directors pursuant to a resolution approved by
the affirmative vote of a majority of the directors then in office. The
resolution calling the special meeting of the board of directors may fix any
convenient place, either within or outside Delaware, as the place for holding
any special meeting of the board of directors.

SECTION 3.06  Meetings by Telephone.  Unless otherwise restricted by the
certificate of incorporation, members of the board of directors may participate
in a meeting of such board by means of conference telephone or other
communications equipment by means of which all persons participating in the
meeting can hear each other, and such participation in a meeting in such manner
shall constitute presence in person at the meeting.

SECTION 3.07  Notice of Meetings.  Notice of each meeting of the board of
directors (except those regular meetings for which notice is not required)
stating the place, day and hour of the meeting shall be given to each director
at least five days prior thereto by the mailing of written notice by first
class, certified or registered mail, or at least two days prior thereto by
personal delivery (including delivery by private courier) of written notice or
by telephone, telegram, telex, cablegram or other similar method, except that in
the case of a meeting to be held pursuant to Section 3.07 notice may be given by
telephone one day prior thereto. The method of notice need not be the same to
each director. Notice shall be deemed to be given when deposited in the United
States mail, with postage thereon prepaid, addressed to the director at his
business or residence address, when delivered or communicated to the director or
when the telegram, telex, cablegram or other form of notice is personally
delivered to the director or delivered to the last address of the director
furnished by him to the corporation for such purpose. The business to be
transacted at, or the purpose of, any meeting of the board of directors shall be
specified in the notice or waiver of notice of such meeting.

SECTION 3.08  Quorum and Manner of Acting.  Except as otherwise may be required
by law, the certificate of incorporation (including, without limitation,
paragraph (d) of Article Fifth thereof) or these bylaws, a majority of the
number of directors fixed in accordance with these bylaws, present in person,
shall constitute a quorum for the transaction of business at any meeting of the
board of directors, and the vote of a majority of the directors present at a
meeting at which a quorum is present shall be the act of the board of directors.
If less than a quorum is present at a meeting, the directors present may adjourn
the meeting from time to time without further notice other than announcement at
the meeting, until a quorum shall be present. No director may vote or act by
proxy or power of attorney at any meeting of the board of directors.

SECTION 3.09  Action Without a Meeting.  Any action required or permitted to be
taken at any meeting of the board of directors or of any committee thereof may
be taken without a meeting, without prior notice and without a vote, if all
members of the board or committee, as the case may be, consent thereto in
writing or by electronic transmission and the writing or writings or electronic
transmission or transmissions are filed with the minutes of the proceedings of
the board or committee, as the case may be.

                                       4

SECTION 3.10  Executive and Other Committees.  The board of directors may
designate one or more committees, each committee to consist of one or more of
the directors of the corporation. The board may designate one or more directors
as alternate members of any committee, who may replace any absent or
disqualified member at any meeting of the committee. In the absence or
disqualification of a member of a committee, the member or members present at
any meeting and not disqualified from voting, whether or not such member or
members constitute a quorum, may unanimously appoint another member of the board
of directors to act at the meeting in the place of any such absent or
disqualified member. Any such committee, to the extent provided in the
resolution of the board of directors, shall have and may exercise all the powers
and authority of the board of directors in the management of the business and
affairs of the corporation, and may authorize the seal of the corporation to be
affixed to all papers which may require it; but no such committee shall have the
power or authority in reference to the following matters: (a) approving or
adopting, or recommending to the stockholders, any action or matter expressly
required by the Delaware General Corporation Law to be submitted to stockholders
for approval or (b) adopting, amending or repealing any bylaw of the
corporation. The delegation of authority to any committee shall not operate to
relieve the board of directors or any member of the board from any
responsibility imposed by law. Subject to the foregoing, the board of directors
may provide such powers, limitations and procedures for such committees as the
board deems advisable. To the extent the board of directors does not establish
other procedures, each committee shall be governed by the procedures set forth
in Sections 3.04 (except as they relate to an annual meeting), 3.05 through 3.09
and 7.01 and 7.02 as if the committee were the board of directors. Each
committee shall keep regular minutes of its meetings, which shall be reported to
the board of directors when required and submitted to the secretary of the
corporation for inclusion in the corporate records.

SECTION 3.11  Compensation.  Unless otherwise restricted by the certificate of
incorporation, the board of directors shall have the authority to fix the
compensation of directors. The directors may be paid their expenses, if any, of
attendance at each meeting of the board of directors and each meeting of any
committee of the board of which he is a member and may be paid a fixed sum for
attendance at each such meeting or a stated salary or both a fixed sum and a
stated salary. No such payment shall preclude any director from serving the
corporation in any other capacity and receiving compensation therefor.

                                   ARTICLE IV

                                    OFFICERS

SECTION 4.01  Number and Qualifications.  The officers of the corporation shall
consist of a chairman of the board, chief executive officer, a president, a
secretary and such other officers, including a vice-chairman or vice-chairmen of
the board, one or more vice-presidents, a treasurer and a controller, as may
from time to time be elected or appointed by the board. In addition, the board
of directors or the chairman of the board may elect or appoint such assistant
and other subordinate officers, including assistant vice-presidents, assistant
secretaries and assistant treasurers, as it or he shall deem necessary or
appropriate. Any number of offices may be held by the same person, except that
no person may simultaneously hold the offices of president and secretary.

SECTION 4.02  Election and Term of Office.  Except as provided in Sections 4.01
and 4.06, the officers of the corporation shall be elected by the board of
directors annually at the first meeting of the board held after each annual
meeting of the stockholders as provided in Section 3.06. If the election of
officers shall not be held as provided herein, such election shall be held as
soon thereafter as may be convenient. Each officer shall hold office until his
successor shall have been duly elected and shall have qualified or until the
expiration of his term in office if elected or appointed for a specified period
of time or until his earlier death, resignation or removal.

SECTION 4.03  Compensation.  Officers shall receive such compensation for their
services as may be authorized or ratified by the board of directors and no
officer shall be prevented from receiving compensation by reason of the fact
that he is also a director of the corporation. Election or appointment as

                                       5
<PAGE>

an officer shall not of itself create a contract or other right to compensation
for services performed by such officer.

SECTION 4.04  Resignation.  Any officer may resign at any time, subject to any
rights or obligations under any existing contracts between the officer and the
corporation, by giving notice to the corporation in writing or by electronic
transmission. An officer's resignation shall take effect upon receipt or, if a
different time of effectiveness is specified therein, at the time stated
therein. Unless otherwise specified therein, the acceptance of such resignation
shall not be necessary to make it effective.

SECTION 4.05  Removal.  Any officer may be removed at any time by the board of
directors, or, in the case of assistant and other subordinate officers, by the
president (whether or not such officer was appointed by the chief executive
officer), whenever in its or his judgment, as the case may be, the best
interests of the corporation will be served thereby, but such removal shall be
without prejudice to the contract rights, if any, of the person so removed.
Election or appointment of an officer shall not in itself create contract
rights.

SECTION 4.06  Vacancies.  A vacancy occurring in any office by death,
resignation, removal or otherwise may be filled by the board of directors, or,
if such office may be filled by the chairman of the board as provided in Section
4.01, by the chairman of the board, for the unexpired portion of the term.

SECTION 4.07  Authority and Duties.  The officers of the corporation shall have
the authority and shall exercise the powers and perform the duties specified
below and as may be additionally specified by the chairman of the board, the
board of directors or these bylaws (and in all cases where the duties of any
officer are not prescribed by the bylaws or the board of directors, such officer

authority to transfer, payment of all transfer taxes, if any, and the
satisfaction of any other requirements of law, including inquiry into and
discharge of any adverse claims of which the corporation has notice, the
corporation or the transfer agent shall issue a new certificate to the person
entitled thereto, cancel the old certificate and record the transaction on the
books maintained for such

                                       7

purpose by or on behalf of the corporation. No transfer of shares shall be
effective until it has been entered on such books. The corporation or a transfer
agent of the corporation may require a signature guaranty or other reasonable
evidence that any signature is genuine and effective before making any transfer.
Transfers of uncertificated shares shall be made in accordance with applicable
provisions of law.

SECTION 5.03  Registered Holders.  The corporation shall be entitled to
recognize the exclusive right of a person registered on its books as the owner
of shares to receive dividends, and to vote as such owner, and to hold liable
for calls and assessments a person registered on its books as the owner of
shares, and shall not be bound to recognize any equitable or other claim to or
interest in such share or shares on the part of any other person, whether or not
it shall have express or other notice thereof, except as otherwise provided by
the laws of Delaware.

SECTION 5.04  Transfer Agents, Registrars and Paying Agents.  The board of
directors may at its discretion appoint one or more transfer agents, registrars
and agents for making payment upon any class of stock, bond, debenture or other
security of the corporation. Such agents and registrars may be located either
within or outside Delaware. They shall have such rights and duties and shall be
entitled to such compensation as may be agreed.

                                   ARTICLE VI

                                INDEMNIFICATION

SECTION 6.01  Directors and Officers.  The corporation shall indemnify its
directors and officers to the fullest extent not prohibited by the Delaware
General Corporation Law or any other applicable law; provided, however, that the
corporation may modify the extent of such indemnification by individual
contracts with its directors and officers; and, provided, further, that the
corporation shall not be required to indemnify any director or officer in
connection with any proceeding (or part thereof) initiated by such person unless
(i) such indemnification is expressly required to be made by law, (ii) the
proceeding was authorized by the Board of Directors of the corporation, (iii)
such indemnification is provided by the corporation, in its sole discretion,
pursuant to the powers vested in the corporation under the Delaware General
Corporation Law or any other applicable law or (iv) such indemnification is
required to be made under Section 6.04.

SECTION 6.02  Employees and Other Agents.  The corporation shall have power to
indemnify its employees and other agents as set forth in the Delaware General
Corporation Law or any other applicable law. The Board of Directors shall have
the power to delegate the determination of whether indemnification shall be
given to any such person to such officers or other persons as the Board of
Directors shall determine.

SECTION 6.03  Expenses.

     (a)  The corporation shall advance to any person who was or is a party or
     is threatened to be made a party to any threatened, pending or completed
     action, suit or proceeding, whether civil, criminal, administrative or
     investigative, by reason of the fact that he is or was a director or
     officer of the corporation, or is or was serving at the request of the
     corporation as a director or officer of another corporation, partnership,
     joint venture, trust or other enterprise, prior to the final disposition of
     the proceeding, promptly following request therefor, all expenses incurred
     by any director or officer in connection with such proceeding upon receipt
     of an undertaking by or on behalf of such person to repay said amounts if
     it should be determined ultimately that such person is not entitled to be
     indemnified under this Article VI or otherwise.

     (b)  Notwithstanding the foregoing, unless otherwise determined pursuant to
     Section 6.05, no advance shall be made by the corporation to an officer of
     the corporation (except by reason of the fact that such officer is or was a
     director of the corporation, in which event this paragraph shall not apply)
     in any action, suit or proceeding, whether civil, criminal, administrative
     or investigative, if a determination is reasonably and promptly made (i) by
     the Board of Directors by a majority vote of a

                                       8
<PAGE>

     quorum consisting of directors who were not parties to the proceeding, or
     (ii) if such quorum is not obtainable, or, even if obtainable, a quorum of
     disinterested directors so directs, by independent legal counsel in a
     written opinion, that the facts known to the decision-making party at the
     time such determination is made demonstrate clearly and convincingly that
     such person acted in bad faith or in a manner that such person did not
     believe to be in or not opposed to the best interests of the corporation.

SECTION 6.04  Enforcement.  Without the necessity of entering into an express
contract, all rights to indemnification and advances to directors and officers
under this Article VI shall be deemed to be contractual rights and be effective
to the same extent and as if provided for in a contract between the corporation
and the director or officer. Any right to indemnification or advances granted by
this Article VI to a director or officer shall be enforceable by or on behalf of
the person holding such right in any court of competent jurisdiction if (i) the
claim for indemnification or advances is denied, in whole or in part, or (ii) no
disposition of such claim is made within ninety (90) days of request therefor.
The claimant in such enforcement action, if successful in whole or in part,
shall be entitled to be paid also the expense of prosecuting his claim. In
connection with any claim for indemnification, the corporation shall be entitled
to raise as a defense to any such action that the claimant has not met the
standards of conduct that make it permissible under the Delaware General
Corporation Law or any other applicable law for the corporation to indemnify the
claimant for the amount claimed. In connection with any claim by an officer of
the corporation (except in any action, suit or proceeding, whether civil,
criminal, administrative or investigative, by reason of the fact that such
officer is or was a director of the corporation) for advances, the corporation
shall be entitled to raise a defense as to any such action clear and convincing
evidence that such person acted in bad faith or in a manner that such person did
not believe to be in or not opposed to the best interests of the corporation, or
with respect to any criminal action or proceeding that such person acted without
reasonable cause to believe that his conduct was lawful. Neither the failure of
the corporation (including its Board of Directors, independent legal counsel or
its stockholders) to have made a determination prior to the commencement of such
action that indemnification of the claimant is proper in the circumstances
because he has met the applicable standard of conduct set forth in the Delaware
General Corporation Law or any other applicable law, nor an actual determination
by the corporation (including its Board of Directors, independent legal counsel
or its stockholders) that the claimant has not met such applicable standard of
conduct, shall be a defense to the action or create a presumption that claimant
has not met the applicable standard of conduct. In any suit brought by a
director or officer to enforce a right to indemnification or to an advancement
of expenses hereunder, the burden of proving that the director or officer is not
entitled to be indemnified, or to such advancement of expenses, under this
Article VI or otherwise shall be on the corporation.

SECTION 6.05  Non-Exclusivity of Rights.  The rights conferred on any person by
this Article VI shall not be exclusive of any other right which such person may
have or hereafter acquire under any applicable statute, provision of the
certificate of incorporation, bylaws, agreement, vote of stockholders or
disinterested directors or otherwise, both as to action in his official capacity
and as to action in another capacity while holding office. The corporation is
specifically authorized to enter into individual contracts with any or all of
its directors, officers, employees or agents respecting indemnification and
advances, to the fullest extent not prohibited by the Delaware General
Corporation Law or any other applicable law.

SECTION 6.06  Survival of Rights.  The rights conferred on any person by this
Article VI shall continue as to a person who has ceased to be a director,
officer, employee or other agent and shall inure to the benefit of the heirs,
executors and administrators of such a person.

SECTION 6.07  Insurance.  To the fullest extent permitted by the Delaware
General Corporation Law, or any other applicable law, the corporation, upon
approval by the Board of Directors, may purchase insurance on behalf of any
person required or permitted to be indemnified pursuant to this Article VI.

SECTION 6.08  Amendments.  Any repeal or modification of this Article VI shall
only be prospective and shall not affect the rights under this Article VI in
effect at the time of the alleged occurrence of any action or omission to act
that is the cause of any proceeding against any agent of the corporation.

                                       9
<PAGE>

SECTION 6.09  Severability.  If this Article VI or any portion hereof shall be
invalidated on any ground by any court of competent jurisdiction, then the
corporation shall nevertheless indemnify each director and officer to the full
extent not prohibited by any applicable portion of this Article VI that shall
not have been invalidated, or by any other applicable law. If this Article VI
shall be invalid due to the application of the indemnification provisions of
another jurisdiction, then the corporation shall indemnify each director and
officer to the full extent under applicable law.

SECTION 6.10  Certain Definitions.  For the purposes of this Article VI, the
following definitions shall apply:

     (a)  The term "proceeding" shall be broadly construed and shall include,
     without limitation, the investigation, preparation, prosecution, defense,
     settlement, arbitration and appeal of, and the giving of testimony in, any
     threatened, pending or completed action, suit or proceeding, whether civil,
     criminal, administrative or investigative.

     (b)  The term "expenses" shall be broadly construed and shall include,
     without limitation, court costs, attorneys' fees, witness fees, fines,
     amounts paid in settlement or judgment and any other costs and expenses of
     any nature or kind incurred in connection with any proceeding.

     (c)  The term "corporation" shall include, in addition to the resulting
     corporation, any constituent corporation (including any constituent of a
     constituent) absorbed in a consolidation or merger which, if its separate
     existence had continued, would have had power and authority to indemnify
     its directors, officers, and employees or agents, so that any person who is
     or was a director, officer, employee or agent of such constituent
     corporation, or is or was serving at the request of such constituent
     corporation as a director, officer, employee or agent of another
     corporation, partnership, joint venture, trust or other enterprise, shall
     stand in the same position under the provisions of this Article VI with
     respect to the resulting or surviving corporation as he would have with
     respect to such constituent corporation if its separate existence had
     continued.

     (d)  References to a "director," "executive officer," "officer,"
     "employee," or "agent" of the corporation shall include, without
     limitation, situations where such person is serving at the request of the
     corporation as, respectively, a director, executive officer, officer,
     employee, trustee or agent of another corporation, partnership, joint
     venture, trust or other enterprise.

     (e)  References to "other enterprises" shall include employee benefit
     plans; references to "fines" shall include any excise taxes assessed on a
     person with respect to an employee benefit plan; and references to "serving
     at the request of the corporation" shall include any service as a director,
     officer, employee or agent of the corporation which imposes duties on, or
     involves services by, such director, officer, employee, or agent with
     respect to an employee benefit plan, its participants, or beneficiaries;
     and a person who acted in good faith and in a manner he reasonably believed
     to be in the interest of the participants and beneficiaries of an employee
     benefit plan shall be deemed to have acted in a manner "not opposed to the
     best interests of the corporation" as referred to in this Article VI.

                                  ARTICLE VII

                                 MISCELLANEOUS

SECTION 7.01  Waivers of Notice.  Whenever notice is required to be given by
law, by the certificate of incorporation or by these bylaws, a written waiver
thereof, signed by the person entitled to said notice or a waiver by electronic
transmission by the person entitled to notice, whether before or after the time
stated therein, shall be deemed equivalent to notice. Attendance of a person at
a meeting or (in the case of a stockholder) by proxy shall constitute a waiver
of notice of such meeting, except when the person attends a meeting for the
express purpose of objecting, at the beginning of the meeting, to the
transaction of any business because the meeting was not lawfully called or
convened. Neither the business to be transacted at, nor the purpose of, any
meeting need be specified in any written waiver of notice or waiver of notice by
electronic transmission unless required by these bylaws to be included in the
notice of such meeting.

                                       10

SECTION 7.02  Presumption of Assent.  A director or stockholder of the
corporation who is present at a meeting of the board of directors or
stockholders at which action on any corporate matter is taken shall be presumed
to have assented to the action taken unless his dissent shall be entered in the
minutes of the meeting or unless he shall file his written dissent to such
action with the person acting as the secretary of the meeting before the
adjournment thereof or shall forward such dissent by registered mail to the
secretary of the corporation immediately after the adjournment of the meeting.
Such right to dissent shall not apply to a director or stockholder who voted in
favor of such action.

SECTION 7.03  Voting of Securities by the Corporation.  Unless otherwise
provided by resolution of the board of directors, on behalf of the corporation
the chairman of the board, chief executive officer, president, secretary,
treasurer or any vice-president shall attend in person or by substitute
appointed by him, or shall execute written instruments appointing a proxy or
proxies to represent the corporation at, all meetings of the stockholders of any
other corporation, association or other entity in which the corporation holds
any stock or other securities, and may execute written waivers of notice with
respect to any such meetings. At all such meetings and otherwise, the chairman
of the board, chief executive officer, president, secretary, treasurer or any
vice-president, in person or by substitute or proxy as aforesaid, may vote the
stock or other securities so held by the corporation and may execute written
consents and any other instruments with respect to such stock or securities and
may exercise any and all rights and powers incident to the ownership of said
stock or securities, subject, however, to the instructions, if any, of the board
of directors.

SECTION 7.04  Seal.  The corporate seal of the corporation shall be in such form
as adopted by the board of directors, and any officer of the corporation may,
when and as required, affix or impress the seal, or a facsimile thereof, to or
on any instrument or document of the corporation.

SECTION 7.05  Fiscal Year.  The fiscal year of the corporation shall be as
established by the board of directors.

SECTION 7.06  Amendments.  These bylaws may be amended or repealed only in the
manner set forth in the certificate of incorporation.

                         PURSUANT TO SECTION 151 OF THE
                GENERAL CORPORATION LAW OF THE STATE OF DELAWARE

                                   ----------

                  UNITEDGLOBALCOM, INC., a corporation organized and existing
under the General Corporation Law of the State of Delaware (the "Issuer"), does
hereby certify that (i) pursuant to authority conferred upon the Board of
Directors of the Issuer by its Second Restated Certificate of Incorporation, as
amended to date, and pursuant to the provisions of Section 151 of the Delaware
General Corporation Law (the "DGCL"), the Board of Directors of the Issuer has
authorized the creation and issuance of shares of the Issuer's Series E
Convertible Preferred Stock (the "Series E Preferred Stock") and appointed a
committee to fix the designations, preferences and rights of such Series E
Preferred Stock and (ii) the following resolution fixing the designations,
preferences and rights of such Series E Preferred Stock was duly adopted by such
committee of the Board of Directors of the Issuer on ____________, 2002, which
resolution remains in full force and effect. Certain capitalized terms used
herein are defined in Section 7.

                  RESOLVED, that pursuant to the authority expressly granted to
                  and vested in the Board of Directors of the Issuer by the
                  provisions of its Second Restated Certificate of Incorporation
                  as amended from time to time (the "Certificate of
                  Incorporation"), and pursuant to Section 151(g) of the General

<PAGE>

                  Delaware, from the 3,000,000 shares of Preferred Stock, $0.01
                  par value per share, of the Issuer authorized to be issued
                  pursuant to the Certificate of Incorporation (the "Preferred
                  Stock"), there shall be a series of Preferred Stock designated
                  the Series E Convertible Preferred Stock, having the number of
                  shares and, to the extent that the designations, powers,
                  preferences and relative and other special rights and the
                  qualifications, limitations and restrictions of such Preferred
                  Stock are not stated and expressed in the Certificate of
                  Incorporation, the powers, preferences and relative and other
                  special rights and the qualifications, limitations and
                  restrictions thereof, as follows:

1.       Designation and Number of Shares

                  1.1 The series of Preferred Stock will be known as the Series
E Convertible Preferred Stock.

                  1.2 The Series E Preferred Stock will consist of 1,500 shares
of the authorized but unissued shares of Preferred Stock of the Issuer.

2.       Dividends, Distributions, Subdivisions, Combinations and
         Reclassifications

                  2.1 Holders of Series E Preferred Stock will not be entitled
to receive any dividends or distributions with respect to shares of Series E
Preferred Stock except as set forth in Section 5 hereof.

                  2.2 The Issuer may not make or pay any distribution or
dividend in shares of Series E Preferred Stock, and may not effect any
subdivision, combination or reclassification of shares of Series E Preferred
Stock.

3.       Ranking

                  3.1 The Series E Preferred Stock will, with respect to
distributions upon the liquidation, winding up or dissolution of the Issuer,
rank:

                           (a) senior to (i) all classes of Common Stock and
(ii) each series of Preferred Stock that is established after the date of this
Certificate of Designation, the terms of which do not expressly provide that
such series will rank senior to or on a parity with the Series E Preferred Stock
as to distributions upon the liquidation, winding up or dissolution of the
Issuer (collectively, with the Common Stock, referred to as the "Junior
Securities");

                           (b) on a parity with each series of Preferred Stock
issued that is established after the date of this Certificate of Designation,
the terms of which expressly provide that such series will rank on a parity with
the Series E Preferred Stock as to distributions upon the liquidation, winding
up or dissolution of the Issuer (collectively referred to as "Parity
Securities"); and

                                       2
<PAGE>

                           (c) junior to (i) each series of Preferred Stock that
is authorized as of the date hereof and (ii) each series of Preferred Stock that
is established after the date of this Certificate of Designation, the terms of
which expressly provide that such series will rank senior to the Series E
Preferred Stock as to distributions upon liquidation, winding up or dissolution
of the Issuer (collectively referred to as "Senior Securities").

4.       Conversion

                  4.1 If the Merger Agreement is terminated, then, following
such termination, each share of Series E Preferred Stock shall automatically
convert into [__________] shares of Class A Stock (as adjusted from time to time
to appropriately reflect the effect of any stock splits, reverse splits, stock
dividends, combinations and other similar events affecting the shares of Class A
Stock and occurring after the date of issuance of the Series E Preferred
Stock).(1)

                  4.2 On the effective date of the conversion of the Series E
Preferred Stock pursuant to Section 4.1, all rights with respect to the shares
of Series E Preferred Stock so converted, including the rights, if any, to
receive notices, will terminate, except the rights of Holders thereof to (1)
receive certificates for the number of shares of Class A Stock into which such
shares of Series E Preferred Stock have been converted; and (2) exercise the
rights to which they are entitled as Holders of Class A Stock.

                  4.3 The Issuer shall at all times reserve and keep available
for issuance upon the conversion of the Series E Preferred Stock, free from
preemptive rights, such number of its authorized but unissued shares of Class A
Stock as will from time to time be sufficient to permit the conversion of all
outstanding shares of Series E Preferred Stock, and shall take all action
required to increase the authorized number of shares of each class of Class A
Stock if at any time there shall be insufficient authorized unissued shares of
Class A Stock to permit such reservation or to permit the conversion of all
outstanding shares of Series E Preferred Stock.

                  4.4 If any shares of Class A Stock that would be issuable upon
conversion pursuant to this Section 4 require registration with or approval of
any Governmental Authority before such shares may be issued upon conversion, the
Issuer will as expeditiously as possible cause such shares to be duly registered
or approved, as the case may be. The Issuer will use commercially reasonable
efforts to list the shares of Class A Stock required to be delivered upon
conversion of shares of Series E Preferred Stock prior to such delivery upon the
principal national securities exchange or association, if any, upon which the
outstanding Class A Stock is listed at the time of such delivery.

--------
(1) Each share of Series E Preferred Stock will convert pursuant to this
provision into a number of shares of United Class A Stock equal to 1/1,500th of
the result (rounded down to the nearest share) of (A) the quotient of X divided
by Y minus (B) X. For purposes of the foregoing, "X" shall be equal to the
aggregate number of shares of United Class A Stock and United Class B Stock
outstanding immediately prior to the Closing and "Y" shall be equal to
0.995049505.

                                       3
<PAGE>

                  4.5 The issuance or delivery of certificates evidencing shares
of Class A Stock upon the conversion of shares of Series E Preferred Stock shall
be made without charge to the Holder of shares of Series E Preferred Stock for
such certificates or for any tax in respect of the issuance or delivery of such
certificates or the securities represented thereby, and such certificates shall
be issued or delivered in the respective names of the Holders of the shares of
Series E Preferred Stock so converted. Certificates for shares of Series E
Preferred Stock shall bear such legends as the Issuer shall from time to time
reasonably deem appropriate.

                  4.6 No fractional shares of Class A Stock or securities
representing fractional shares of Class A Stock will be issued upon conversion
of the Series E Preferred Stock. If more than one share of Series E Preferred
Stock is held by a particular Holder at the time of such conversion, the number
of full shares of Class A Stock that shall be issuable upon conversion thereof
shall be computed on the basis of the aggregate number of shares of Series E
Preferred Stock held by such Holder. Any fractional shares of Class A Stock
shall instead be rounded down to the nearest whole share if such fraction is
less than 0.5 and rounded up to the nearest whole share if such fraction is
equal to or greater than 0.5 and the Issuer shall issue upon such conversion the
appropriate number of full shares of Class A Stock.

                  4.7 Each share of Class A Stock delivered to a Holder as a
result of the conversion of any shares of Series E Preferred Stock pursuant to
this Section 4 shall be accompanied by any rights associated generally with each
other share of Class A Stock outstanding as of the effective date of the
conversion.

5.       Liquidation Preference

                  5.1 Upon any voluntary or involuntary liquidation, dissolution
or winding up of the Issuer, a Holder of a share of Series E Preferred Stock
will be entitled to be paid, out of assets of the Issuer available for
distribution, the Liquidation Preference of such share, and no other amount with
respect to such share, before any distribution is made on any Junior Securities.

                  5.2 If, upon any voluntary liquidation, dissolution or winding
up of the Issuer, the amounts payable with respect to the Liquidation Preference
of the Series E Preferred Stock and the liquidation preferences of all other
Parity Securities are not paid in full, the Holders of the Series E Preferred
Stock and the Parity Securities will share pro rata in proportion to the full
distribution to which each would otherwise be entitled in such liquidation,
dissolution or winding up.

                  5.3 Neither the sale, conveyance, exchange or transfer (for
cash, shares of stock, securities or other consideration) of all or
substantially all of the property or business of the Issuer (other than in
connection with the winding up of its business), nor the merger (including
without limitation the New United/Old United Merger) or consolidation of the
Issuer with or into any other Person, will be deemed to be a dissolution,
liquidation, or winding up, voluntary or involuntary, of the Issuer.

6.       No Voting Rights

                  6.1 Holders of the Series E Preferred Stock have no voting
rights except as required by law.

<PAGE>

                  6.2 To the fullest extent permitted by law and the Certificate
of Incorporation of the Issuer, any action that may be taken by a vote of the
Series E Preferred Stock voting as a separate class may be taken without a
meeting, without prior notice and without a vote if a consent or consents in
writing, setting forth the action so taken, shall be signed by the Holders of
outstanding shares of Series E Preferred Stock having not less than the minimum
number of votes that would be necessary to authorize or take such action at a
meeting at which all shares of Series E Preferred Stock entitled to vote thereon
were present and voted and shall be delivered to the Issuer by delivery to its
registered office in the State of Delaware, the Issuer's principal place of
business, or an officer or agent of the Issuer having custody of the books in

for any purpose or purposes, unless otherwise prescribed by statute, may be
called only by the Chairman of the board of directors or by the board of
directors pursuant to a resolution approved by the affirmative vote of a
majority of directors then in office. Such request shall state the purpose or
purposes of the proposed meeting.

         Section 2.03 Place of Meeting. Each meeting of the stockholders shall
be held at such place, either within or outside Delaware, as may be designated
in the notice of meeting, or, if no place is designated in the notice, at the
principal office of the corporation.

         Section 2.04 Notice of Meetings. Except as otherwise required by law,
notice in writing or by electronic transmission of each meeting of the
stockholders stating the place, day and hour of the meeting, the means of remote
communications, if any, by which stockholders and proxy holders may

                                       1
<PAGE>

be deemed to be present in person and vote at such meeting and, in the case of a
special meeting, the purpose or purposes for which the meeting is called, shall
be given, either personally (including delivery by private courier) or by first
class, certified or registered mail, or by electronic transmission, to each
stockholder of record entitled to notice of such meeting, not less than ten nor
more than 60 days before the date of the meeting. Such notice shall be deemed to
be given, if personally delivered, when delivered to the stockholder, and, if
mailed, when deposited in the United States mail, postage prepaid, directed to
the stockholder at his address as it appears on the records of the corporation,
and if by electronic transmission, when posted on an electronic network or
directed to the stockholder at an electronic mail address at which the
stockholder has consented to receive notice. If notice of two consecutive annual
meetings and all notices of meetings or the taking of action by written consent
without a meeting to any stockholder during the period between such two
consecutive annual meetings, or all, and at least two, payments (if sent by
first class mail) of dividends or interest on securities during a 12-month
period, have been mailed or directed addressed to such person at his address as
shown on the records of the corporation and have been returned undeliverable,
the giving of such notice to such person shall not be required until another
address for such person is delivered to the corporation. When a meeting is
adjourned to another time or place, notice need not be given of the adjourned
meeting if the time and place thereof are announced at the meeting at which the
adjournment is taken. At the adjourned meeting the corporation may transact any
business that might have been transacted at the original meeting. If the
adjournment is for more than 30 days, or if after the adjournment a new record
date is fixed for the adjourned meeting, notice of the adjourned meeting shall
be given to each stockholder of record entitled to vote at the meeting in
accordance with the foregoing provisions of this Section 2.04.

         Section 2.05 Fixing Date for Determination of Stockholders of Record.
For the purpose of determining stockholders entitled to notice of or to vote at
any meeting of stockholders or any adjournment thereof, or entitled to receive
payment of any dividend or other distribution or allotment of any rights, or
entitled to exercise any rights in respect of any change, conversion or exchange
of stock or for any other lawful action, the board of directors may fix, in
advance, a date as the record date for any such determination of stockholders,
which date shall be not more than 60 nor less than ten days before the date of
such meeting, and not more than 60 days prior to any other action. If no record
date is fixed then the record date shall be, for determining stockholders
entitled to notice of or to vote at a meeting of stockholders, the close of
business on the day next preceding the day on which notice is given, or, if
notice is waived, the close of business on the day next preceding the day on
which the meeting is held, or, for determining stockholders for any other
purpose, the close of business on the day on which the board of directors adopts
the resolution relating thereto. A determination of stockholders of record
entitled to notice of or to vote at a meeting of stockholders shall apply to any
adjournment of the meeting; provided, however, that the board of directors may
fix a new record date for the adjourned meeting. Notwithstanding the foregoing
provisions of this Section 2.05, the record date for determining stockholders
entitled to take, or receive notice of, corporate action in writing without a
meeting as provided in Section 2.11 shall be determined as provided in such
Section.

         Section 2.06 Voting List. The officer who has charge of the stock
ledger of the corporation shall prepare and make, at least ten days before every
meeting of stockholders, a complete list of the stockholders entitled to vote at
the meeting, arranged in alphabetical order, and showing the address of each
stockholder and the number of shares registered in the name of each stockholder.
Nothing contained in this Section 2.06 shall require the corporation to include
electronic mail addresses or other electronic contact information on such list.
Such list shall be open to the examination of any stockholder, for any purpose
germane to the meeting, for a period of at

                                       2
<PAGE>

least ten days prior to the meeting, either (a) on a reasonably accessible
electronic network, provided that the information required to gain access to
such list is provided with the notice of the meeting, or (b) during ordinary
business hours, at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or, if not so
specified, at the place where the meeting is to be held. In the event that the
corporation determines to make the list available on an electronic network, the
corporation may take reasonable steps to ensure that such information is
available only to stockholders of the corporation. If the meeting is to be held
at a place, the list shall also be produced and kept at the time and place of
the meeting during the whole time thereof, and may be inspected by any
stockholder who is present. If the meeting is to be held solely by means of
remote communication, then the list shall also be open to the examination of any
stockholder during the whole time of the meeting on a reasonably accessible
electronic network, and the information required to access such list shall be
provided with the notice of the meeting.

         Section 2.07 Proxies. Each stockholder entitled to vote at a meeting of
stockholders or to express consent or dissent to corporate action in writing
without a meeting may authorize another person or persons to act for him by
proxy, but no such proxy shall be voted or acted upon after three years from its
date, unless the proxy provides for a longer period.

         Section 2.08 Quorum and Manner of Acting. At all meetings of
stockholders, a majority of the combined voting power of the outstanding shares
of the corporation entitled to vote, represented in person or by proxy, shall
constitute a quorum. If a quorum is present, the affirmative vote of a majority
of the shares represented at a meeting at which a quorum is present and entitled
to vote on the subject matter shall be the act of the stockholders, unless the
vote of a greater proportion or number or voting by classes is otherwise
required by law, the certificate of incorporation or these bylaws. In the
absence of a quorum, a majority of the shares so represented may adjourn the
meeting from time to time in accordance with Section 2.04, until a quorum shall
be present or represented.

         Section 2.09 Action Without a Meeting.

            (a) Written Consent. Unless otherwise provided in the certificate of
incorporation, any action required or permitted to be taken at any meeting of
the stockholders may be taken without a meeting, without prior notice and
without a vote, if a consent in writing, setting forth the action so taken,
shall be signed by the holders of outstanding stock having not less than the
minimum number of votes that would be necessary to authorize or take such action
at a meeting at which all shares entitled to vote thereon were present and voted
(which consent may be signed in counterparts). Every written consent shall bear
the date of signature of each stockholder who signs the consent and no written
consent shall be effective to take the corporate action referred to therein
unless, within 60 days of the earliest dated consent delivered to the
corporation in the manner required by the Delaware General Corporation Law,
written consents signed by a sufficient number of stockholders to take the
action are delivered to the corporation in the manner required by the Delaware
General Corporation Law.

            (b) Determination of Stockholders Entitled to Act By Consent. For
purposes of determining stockholders entitled to consent to corporate action in
writing without a meeting, the board of directors may fix, in advance, a date as
the record date for any such determination of stockholders, which date shall be
not more than ten days after the date upon which the resolution fixing the
record date is adopted by the board of directors. If no record date has been
fixed by the board of directors, the record date for determining stockholders
entitled to consent to corporate action in writing without a meeting, when no
prior action by the board of directors is required by the

                                       3
<PAGE>

Delaware General Corporation Law, shall be the first date on which a signed
written consent setting forth the action taken or proposed to be taken is
delivered to the corporation in the manner required by the Delaware General
Corporation Law. If no record date has been fixed by the board of directors and
prior action by the board of directors is required by the Delaware General
Corporation Law, the record date for determining stockholders entitled to
consent to corporate action in writing without a meeting shall be the close of
business on the day on which the board of directors adopts the resolution taking
such prior action.

            (c) Notice to Non-Consenting Stockholders. Prompt written notice of
the taking of corporate action without a meeting by less than unanimous written
consent shall be given to those stockholders who have not consented in writing.
Such notice shall be given in accordance with the applicable provisions of
Section 2.04.

                                   ARTICLE III

                               Board of Directors

         Section 3.01 General Powers. The business and affairs of the
corporation shall be managed by or under the direction of its board of
directors, except as otherwise provided in the Delaware General Corporation Law
or the certificate of incorporation.

         Section 3.02 Number, Tenure and Qualifications. The number of directors
of the corporation and the manner of electing such directors shall be as set
forth in the certificate of incorporation. Directors shall be elected at each
annual meeting of stockholders. Each director shall hold office until his
successor shall have been elected and qualified or until his earlier death,
resignation or removal. Directors need not be residents of Delaware or
stockholders of the corporation.

         Section 3.03 Resignation. Any director may resign at any time by giving
notice to the corporation in writing or by electronic transmission. A director's
resignation shall take effect upon receipt or, if a different time of
effectiveness is specified therein, at the time specified therein. Unless
otherwise specified therein, the acceptance of such resignation shall not be
necessary to make it effective.

         Section 3.04 Regular Meetings. A regular meeting of the board of
directors shall be held immediately after and at the same place as the annual
meeting of stockholders, or as soon thereafter as conveniently may be, at the
time and place, either within or without Delaware, determined by the board, for
the purpose of electing officers and for the transaction of such other business
as may come before the meeting. Failure to hold such a meeting, however, shall
not invalidate any action taken by any officer then or thereafter in office. The
board of directors may provide by resolution the time and place, either within
or outside Delaware, for the holding of additional regular meetings without
other notice than such resolution.

         Section 3.05 Special Meetings. Special meetings of the board of
directors may be called only by the Chief Executive Officer or any member of the
board of directors. The notice of the special meeting of the board of directors
may fix any convenient place, either within or outside Delaware, as the place
for holding any special meeting of the board of directors.

         Section 3.06 Meetings by Telephone. Unless otherwise restricted by the
certificate of incorporation, members of the board of directors may participate
in a meeting of such board by means of conference telephone or other
communications equipment by means of which all persons participating in the
meeting can hear each other, and such participation in a meeting in such manner
shall constitute presence in person at the meeting.

         Section 3.07 Notice of Meetings. Notice of each meeting of the board of
directors (except those regular meetings for which notice is not required)
stating the place, day and hour of the meeting shall be given to each director
at least five days prior thereto by the mailing of written notice by first
class, certified or registered mail, or at least two days prior thereto by
personal delivery (including delivery by private courier) of written notice or
by telephone, telegram, telex, cablegram or other similar method, except that in
the case of a meeting to be held pursuant to Section 3.06 notice may be given by
telephone one day prior thereto. The method of notice need not be the same to
each director. Notice shall be deemed to be given when deposited in the United
States mail, with postage thereon prepaid, addressed to the director at his
business or residence address, when delivered or communicated to the director or
when the telegram, telex, cablegram or other form of notice is personally
delivered to the director or delivered to the last address of the director
furnished by him to the corporation for such purpose. The business to be
transacted at, or the purpose of, any meeting of the board of directors shall be
specified in the notice or waiver of notice of such meeting.

         Section 3.08 Quorum and Manner of Acting. Except as otherwise may be
required by law, the certificate of incorporation (including, without
limitation, paragraph (d) of Article Fifth thereof) or these bylaws, a majority
of the number of directors fixed in accordance with these bylaws, present in
person, shall constitute a quorum for the transaction of business at any meeting
of the board of directors, and the vote of a majority of the directors present
at a meeting at which a quorum is present shall be the act of the board of
directors. If less than a quorum is present at a meeting, the directors present
may adjourn the meeting from time to time without further notice other than
announcement at the meeting, until a quorum shall be present. No director may
vote or act by proxy or power of attorney at any meeting of the board of
directors.

         Section 3.09 Action Without a Meeting. Any action required or permitted
to be taken at any meeting of the board of directors or of any committee thereof
may be taken without a meeting, without prior notice and without a vote, if all
members of the board or committee, as the case may be, consent thereto in
writing or by electronic transmission and the writing or writings or electronic
transmission or transmissions are filed with the minutes of the proceedings of
the board or committee, as the case may be.

         Section 3.10 Executive and Other Committees. The board of directors may
designate one or more committees, each committee to consist of one or more of
the directors of the corporation. The board may designate one or more directors
as alternate members of any committee, who may replace any absent or
disqualified member at any meeting of the committee. In the absence or
disqualification of a member of a committee, the member or members present at
any meeting and not disqualified from voting, whether or not such member or
members constitute a quorum, may unanimously appoint another member of the board
of directors to act at the meeting in the place of any such absent or
disqualified member. Any such committee, to the extent provided in the
resolution of the board of directors, shall have and may exercise all the powers
and authority of the board of directors in the management of the business and
affairs of the corporation, and may authorize the seal of the corporation to be
affixed to all papers which may require it; but no such committee shall have the
power or authority in reference to the following matters: (a) approving or

                                       5
<PAGE>

adopting, or recommending to the stockholders, any action or matter expressly
required by the Delaware General Corporation Law to be submitted to stockholders
for approval or (b) adopting, amending or repealing any bylaw of the
corporation. The delegation of authority to any committee shall not operate to
relieve the board of directors or any member of the board from any
responsibility imposed by law. Subject to the foregoing, the board of directors
may provide such powers, limitations and procedures for such committees as the
board deems advisable. To the extent the board of directors does not establish
other procedures, each committee shall be governed by the procedures set forth
in Sections 3.04 (except as they relate to an annual meeting), 3.05 through 3.09
and 7.01 and 7.02 as if the committee were the board of directors. Each
committee shall keep regular minutes of its meetings, which shall be reported to
the board of directors when required and submitted to the secretary of the
corporation for inclusion in the corporate records.

         Section 3.11 Compensation. Unless otherwise restricted by the
certificate of incorporation, the board of directors shall have the authority to
fix the compensation of directors. The directors may be paid their expenses, if
any, of attendance at each meeting of the board of directors and each meeting of
any committee of the board of which he is a member and may be paid a fixed sum
for attendance at each such meeting or a stated salary or both a fixed sum and a
stated salary. No such payment shall preclude any director from serving the
corporation in any other capacity and receiving compensation therefor.

                                   ARTICLE IV

                                    Officers

vice-presidents, a treasurer and a controller, as may from time to time be
elected or appointed by the board. In addition, the board of directors or the
chief executive officer may elect or appoint such assistant and other
subordinate officers, including assistant vice-presidents, assistant secretaries
and assistant treasurers, as it or he shall deem necessary or appropriate. Any
number of offices may be held by the same person, except that no person may
simultaneously hold the offices of president and secretary.

         Section 4.02 Election and Term of Office. Except as provided in
Sections 4.01 and 4.06, the officers of the corporation shall be elected by the
board of directors annually at the first meeting of the board held after each
annual meeting of the stockholders as provided in Section 3.04. If the election
of officers shall not be held as provided herein, such election shall be held as
soon thereafter as may be convenient. Each officer shall hold office until his
successor shall have been duly elected and shall have qualified or until the
expiration of his term in office if elected or appointed for a specified period
of time or until his earlier death, resignation or removal.

         Section 4.03 Compensation. Officers shall receive such compensation for
their services as may be authorized or ratified by the board of directors and no
officer shall be prevented from receiving compensation by reason of the fact
that he is also a director of the corporation. Election or appointment as an
officer shall not of itself create a contract or other right to compensation for
services performed by such officer.

                                       6
<PAGE>

         Section 4.04 Resignation. Any officer may resign at any time, subject
to any rights or obligations under any existing contracts between the officer

electronic transmission. An officer's resignation shall take effect upon receipt
or, if a different time of effectiveness is specified therein, at the time
stated therein. Unless otherwise specified therein, the acceptance of such
resignation shall not be necessary to make it effective.

         Section 4.05 Removal. Any officer may be removed at any time by the
board of directors, or, in the case of assistant and other subordinate officers,
by the chief executive officer, whenever in its or his judgment, as the case may
be, the best interests of the corporation will be served thereby, but such
removal shall be without prejudice to the contract rights, if any, of the person
so removed. Election or appointment of an officer shall not in itself create
contract rights.

         Section 4.06 Vacancies. A vacancy occurring in any office by death,
resignation, removal or otherwise may be filled by the chief executive officer.

         Section 4.07 Authority and Duties. The officers of the corporation
shall have the authority and shall exercise the powers and perform the duties

            (a) The corporation shall advance to any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative, by reason of the fact that he is or was a director or officer of
the corporation, or is or was serving at the request of the corporation as a
director or officer of another corporation, partnership, joint venture, trust or
other enterprise, prior to the final disposition of the proceeding, promptly
following request therefor, all expenses incurred by any director or officer in
connection with such proceeding upon receipt of an undertaking by or on behalf
of such person to repay said amounts if it should be determined ultimately that
such person is not entitled to be indemnified under this Article VI or
otherwise.

            (b) Notwithstanding the foregoing, unless otherwise determined
pursuant to Section 6.05, no advance shall be made by the corporation to an
officer of the corporation (except by reason of the fact that such officer is or
was a director of the corporation, in which event this paragraph shall not
apply) in any action, suit or proceeding, whether civil, criminal,
administrative or investigative, if a determination is reasonably and promptly
made (i) by the Board of Directors by a majority vote of a quorum consisting of
directors who were not parties to the proceeding, or (ii) if such quorum is not
obtainable, or, even if obtainable, a quorum of disinterested directors so
directs, by independent legal counsel in a written opinion, that the facts known
to the decision-making party at the time such determination is made demonstrate
clearly and convincingly that such person acted in bad faith or in a manner that
such person did not believe to be in or not opposed to the best interests of the
corporation.

         6.04 Enforcement. Without the necessity of entering into an express
contract, all rights to indemnification and advances to directors and officers
under this Article VI shall be deemed to be contractual rights and be effective
to the same extent and as if provided for in a contract between the corporation
and the director or officer. Any right to indemnification or advances granted by
this Article VI to a director or officer shall be enforceable by or on behalf of
the person holding such right in any court of competent jurisdiction if (i) the
claim for indemnification or advances is denied, in whole or in part, or (ii) no
disposition of such claim is made within ninety (90) days of request therefor.
The claimant in such enforcement action, if successful in whole or in part,
shall be entitled to be paid also the expense of prosecuting his claim. In
connection with any claim for indemnification, the corporation shall be entitled
to raise as a defense to any such action that the claimant has not met the
standards of conduct that make it permissible under the Delaware General
Corporation Law or any other applicable law for the corporation to indemnify the
claimant for the amount claimed. In connection with any claim by an officer of
the corporation (except in any action, suit or proceeding, whether civil,
criminal, administrative or investigative, by reason of the fact that such
officer is or was a director of the corporation) for advances, the corporation
shall be entitled to raise a defense as to any such action clear and convincing
evidence that such person acted in bad

                                       10
<PAGE>

faith or in a manner that such person did not believe to be in or not opposed to
the best interests of the corporation, or with respect to any criminal action or
proceeding that such person acted without reasonable cause to believe that his
conduct was lawful. Neither the failure of the corporation (including its Board
of Directors, independent legal counsel or its stockholders) to have made a
determination prior to the commencement of such action that indemnification of
the claimant is proper in the circumstances because he has met the applicable
standard of conduct set forth in the Delaware General Corporation Law or any
other applicable law, nor an actual determination by the corporation (including
its Board of Directors, independent legal counsel or its stockholders) that the
claimant has not met such applicable standard of conduct, shall be a defense to
the action or create a presumption that claimant has not met the applicable
standard of conduct. In any suit brought by a director or officer to enforce a
right to indemnification or to an advancement of expenses hereunder, the burden
of proving that the director or officer is not entitled to be indemnified, or to
such advancement of expenses, under this Article VI or otherwise shall be on the
corporation.

         6.05 Non-Exclusivity of Rights. The rights conferred on any person by
this Article VI shall not be exclusive of any other right which such person may
have or hereafter acquire under any applicable statute, provision of the
certificate of incorporation, bylaws, agreement, vote of stockholders or
disinterested directors or otherwise, both as to action in his official capacity
and as to action in another capacity while holding office. The corporation is
specifically authorized to enter into individual contracts with any or all of
its directors, officers, employees or agents respecting indemnification and
advances, to the fullest extent not prohibited by the Delaware General
Corporation Law or any other applicable law.

         6.06 Survival of Rights. The rights conferred on any person by this
Article VI shall continue as to a person who has ceased to be a director,
officer, employee or other agent and shall inure to the benefit of the heirs,
executors and administrators of such a person.

         6.07 Insurance. To the fullest extent permitted by the Delaware General
Corporation Law, or any other applicable law, the corporation, upon approval by
the Board of Directors, may purchase insurance on behalf of any person required
or permitted to be indemnified pursuant to this Article VI.

         6.08 Amendments. Any repeal or modification of this Article VI shall
only be prospective and shall not affect the rights under this Article VI in
effect at the time of the alleged occurrence of any action or omission to act
that is the cause of any proceeding against any agent of the corporation.

         6.09 Severability. If this Article VI or any portion hereof shall be
invalidated on any ground by any court of competent jurisdiction, then the
corporation shall nevertheless indemnify each director and officer to the full
extent not prohibited by any applicable portion of this Article VI that shall
not have been invalidated, or by any other applicable law. If this Article VI
shall be invalid due to the application of the indemnification provisions of
another jurisdiction, then the corporation shall indemnify each director and
officer to the full extent under applicable law.

         6.10 Certain Definitions. For the purposes of this Article VI, the
following definitions shall apply:

            (a) The term "proceeding" shall be broadly construed and shall
include, without limitation, the investigation, preparation, prosecution,
defense, settlement, arbitration and appeal of, and the giving of testimony in,
any threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative.

nature or kind incurred in connection with any proceeding.

            (c) The term "corporation" shall include, in addition to the
resulting corporation, any constituent corporation (including any constituent of
a constituent) absorbed in a consolidation or merger which, if its separate
existence had continued, would have had power and authority to indemnify its
directors, officers, and employees or agents, so that any person who is or was a
director, officer, employee or agent of such constituent corporation, or is or
was serving at the request of such constituent corporation as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise, shall stand in the same position under the provisions
of this Article VI with respect to the resulting or surviving corporation as he
would have with respect to such constituent corporation if its separate
existence had continued.

            (d) References to a "director," "executive officer," "officer,"
"employee," or "agent" of the corporation shall include, without limitation,
situations where such person is serving at the request of the corporation as,
respectively, a director, executive officer, officer, employee, trustee or agent
of another corporation, partnership, joint venture, trust or other enterprise.

            (e) References to "other enterprises" shall include employee benefit
plans; references to "fines" shall include any excise taxes assessed on a person
with respect to an employee benefit plan; and references to "serving at the
request of the corporation" shall include any service as a director, officer,
employee or agent of the corporation which imposes duties on, or involves

employee benefit plan, its participants, or beneficiaries; and a person who
acted in good faith and in a manner he reasonably believed to be in the interest
of the participants and beneficiaries of an employee benefit plan shall be
deemed to have acted in a manner "not opposed to the best interests of the
corporation" as referred to in this Article VI.

                                   ARTICLE VII

by law, by the certificate of incorporation or by these bylaws, a written waiver
thereof, signed by the person entitled to said notice or a waiver by electronic
transmission by the person entitled to notice, whether before or after the time
stated therein, shall be deemed equivalent to notice. Attendance of a person at
a meeting or (in the case of a stockholder) by proxy shall constitute a waiver
of notice of such meeting, except when the person attends a meeting for the
express purpose of objecting, at the beginning of the meeting, to the
transaction of any business because the meeting was not lawfully called or
convened. Neither the business to be transacted at, nor the purpose of, any
meeting need be specified in any written waiver of notice or waiver of notice by
electronic transmission unless required by these bylaws to be included in the
notice of such meeting.

         Section 7.02 Presumption of Assent. A director or stockholder of the

<PAGE>

the minutes of the meeting or unless he shall file his written dissent to such
action with the person acting as the secretary of the meeting before the
adjournment thereof or shall forward such dissent by registered mail to the
secretary of the corporation immediately after the adjournment of the meeting.
Such right to dissent shall not apply to a director or stockholder who voted in
favor of such action.

         Section 7.03 Voting of Securities by the Corporation. Unless otherwise
provided by resolution of the board of directors, on behalf of the corporation
the chairman of the board, chief executive officer, chief operating officer,
chief financial officer, president, secretary, treasurer or any vice-president
shall attend in person or by substitute appointed by him, or shall execute
written instruments appointing a proxy or proxies to represent the corporation
at, all meetings of the stockholders of any other corporation, association or
other entity in which the corporation holds any stock or other securities, and
may execute written waivers of notice with respect to any such meetings. At all
such meetings and otherwise, the chairman of the board, chief executive officer,
chief operating officer, chief financial officer, president, secretary,
treasurer or any vice-president, in person or by substitute or proxy as
aforesaid, may vote the stock or other securities so held by the corporation and
may execute written consents and any other instruments with respect to such
stock or securities and may exercise any and all rights and powers incident to
the ownership of said stock or securities, subject, however, to the
instructions, if any, of the board of directors.

         Section 7.04 Seal. The corporate seal of the corporation shall be in
such form as adopted by the board of directors, and any officer of the
corporation may, when and as required, affix or impress the seal, or a facsimile

SECTION 2.  Action by Founders or Liberty Parties.

Whenever this Agreement contemplates any action to be taken by the Founder
Parties, each of the Founder Parties shall act at the direction of Controlling
Principals and Controlling Principals shall be (and hereby are) authorized in
such circumstances to take any contemplated action on behalf of all of the
Founder Parties. The Liberty Parties and United will be entitled to rely, as
binding on all the Founders, on any instrument signed by Controlling Principals
and on any representation by a Principal that such Principal is a Controlling
Principal or by a group of Principals that such Principals are Controlling
Principals. Whenever this Agreement contemplates any action to be taken by the
Liberty Parties or their Affiliates, each such party shall act at the direction
of Liberty and Liberty shall be (and hereby is) authorized to take any
contemplated action on behalf of all of the Liberty Parties. The Founder Parties
and United will be entitled to rely, as binding on all the Liberty Parties, on
any instrument signed by Liberty.

SECTION 3.  Limitation on Conversion of Class C Stock; Other Covenants.

     (a)  Prior to a Conversion Event, the Liberty Parties will not convert
     shares of Class C Stock into Class A Stock if, after giving effect to such
     conversion, the aggregate voting power of the shares of Class A Stock and
     Class B Stock then owned by the Liberty Parties would (x) exceed 50% of the
     combined voting power of the shares of Class A Stock and Class B Stock then
     outstanding, or (y) constitute a greater percentage of the combined voting
     power of the shares of Class A Stock and Class B Stock then outstanding
     than the percentage represented by the aggregate voting power of the shares
     of Class A Stock and Class B Stock then Beneficially Owned by the Founder
     Parties, provided that the limitations set forth in clauses (x) and (y) on
     the Liberty Parties' right to convert the Class C Stock (i) will terminate
     if the aggregate voting power of the shares of Class A Stock and Class B
     Stock Beneficially Owned by any other Person or Group (other than a Group
     that is controlled by one or more Controlling Principals and consists
     solely of Founder Parties) exceeds either of such percentages and (ii) will
     not apply to any conversion of Class C Stock into Class A Stock in
     connection with a sale or hedging transaction or to any related pledge
     involving Class A Stock.

     (b)  Without the prior written consent of Liberty, which consent may be
     granted or withheld in Liberty's sole discretion, United will not take any
     action and will not permit any action to be taken on its behalf, and will
     use its best commercially reasonable efforts to prevent any action from
     being taken by or on behalf of any of its Affiliates, that would result in
     United, Old United or any of their respective Affiliates being subject to
     or bound by any Change of Control Covenant, unless any Change of Control
     involving or caused by the action of Liberty, Liberty Global or any of
     their respective Affiliates (other than a transfer by any of the foregoing
     to an unaffiliated third party of Control of United, if such Control is
     obtained in the future) is exempted from the application and effects of
     such Change of Control Covenant. United will not be deemed to be in breach
     of the foregoing as a result of its or its Affiliates entering into or
     maintaining in the ordinary course of business a License granted by a
     Governmental Authority that includes a Change of Control Covenant provided
     that (i) such License is of the kind and nature that customarily requires
     approval of the Governmental Authority granting the same for a Change of
     Control, (ii) the applicable Change of Control Covenant includes only terms
     customarily imposed by such Governmental Authority in similar
     circumstances, (iii) the maximum penalty for breach of such Change of
     Control Covenant is termination of the applicable License, and (iv) United
     used its best commercially reasonable efforts to obtain the exemption from
     the application and effects of such Change of Control Covenant contemplated
     by the preceding sentence. Without the prior written consent of Liberty,
     which consent may be granted or withheld in Liberty's sole discretion,
     United will not take any action or permit any

                                       7
<PAGE>

     action to be taken that would, or fail to take any action or permit any
     action to be omitted where such failure or omission would, extend or
     perpetuate the applicability of any Change of Control Covenant in effect as
     of May 25, 2001 under the Current Bonds beyond the maturity date in effect
     as of May 25, 2001 of the Current Bonds to which they relate. United will
     use its best commercially reasonable efforts to take such actions as will
     cause the conditions necessary to permit the conversion in full of the
     Class C Stock into Class B Stock to be satisfied.

     (c)  If, following the occurrence of a Class B Event, any vote or other
     action of United's stockholders is required in connection with the
     acquisition of shares of Class B Stock by a Liberty Party or any of its
     Affiliates pursuant to their purchase rights under the Standstill
     Agreement, United and the Founders and their Permitted Transferees will use
     their respective best commercially reasonable efforts to cause such vote or
     other action to be taken, including calling a special meeting of
     stockholders or soliciting a written consent of stockholders, and voting
     all Equity Securities held by such Persons at such meeting in person or by
     proxy or signing a written consent of stockholders in lieu of a meeting.

SECTION 4.  Founders' Right of First Offer.

     (a)  No Liberty Party shall Transfer any Subject Shares to any Person other
     than a Permitted Transferee in compliance with Section 6, or convert any
     Subject Shares to Class A Stock, unless, prior to such Transfer or
     conversion, the Liberty Parties first offer to sell the Subject Shares
     proposed to be Transferred or converted (the "Liberty Offered Shares") to
     the Founders by delivering a written notice (a "Liberty Offer Notice") to
     the Founders. The Liberty Offer Notice shall state the number and class of
     Liberty Offered Shares and the price per share (the "Liberty Offer Price")
     at which such Liberty Party is offering the Liberty Offered Shares to the
     Founders and shall constitute a binding, irrevocable offer, subject to the
     provisions of this Section 4, to sell the Liberty Offered Shares to the
     Founders and any Designated Purchaser (as defined below) at the Liberty
     Offer Price. Prior to the occurrence of a Conversion Event, the number of
     Liberty Offered Shares proposed to be Transferred, when taken together with
     the aggregate number of shares of Class A Stock, received upon conversion
     of Subject Shares, Beneficial Ownership of which shares of Class A Stock
     was theretofore Transferred by a Liberty Party, other than to a Permitted
     Transferee or a Founder Party or Designated Purchaser or to United, shall
     not exceed the sum of the total number of shares of Class A Stock of which
     the Liberty Parties acquired Beneficial Ownership after the date hereof
     (from Persons other than United (including upon the conversion of Class C
     Stock) or the Founder Parties) plus the total number of shares of Class A
     Stock received in the United/New United Merger upon conversion of shares of
     Class A Common Stock, par value $0.01 per share, of Old United acquired by
     the Liberty Parties after December 3, 2001. In order to accept the offer of
     the Liberty Offered Shares, Controlling Principals must deliver a written
     notice of acceptance (a "Founder Acceptance Notice") to the Liberty Parties
     agreeing to purchase all, but not less than all, of the Liberty Offered
     Shares at the Liberty Offer Price. In order to be effective, a Founder
     Acceptance Notice must (i) be signed by Controlling Principals (either
     personally or by a duly authorized agent), (ii) designate which Founders
     and Designated Purchasers are to purchase the Liberty Offered Shares and
     the number of shares to be purchased by each such Founder and Designated
     Purchaser and (iii) be delivered to the Liberty Parties no later than 5:00
     p.m. Denver, Colorado time on the last day of (A) if such Liberty Offer
     Notice relates to a number of Subject Shares, the conversion of which to
     Class A Stock would not reduce the aggregate voting power for the election
     of directors of Equity Securities subject to this Agreement below 80% of
     the total voting power for the election of directors of all Equity
     Securities outstanding, in each case calculated as if all Class C Stock had
     been converted to Class B Stock, the two-Business Day period (a
     "Two-Business Day Election Period") following the date the Liberty Offer
     Notice is given; or (B) in all other cases, the sixty-day period (a
     "Sixty-Day Election Period") following the date the Liberty Offer Notice is
     given. A duly completed and delivered Founder Acceptance Notice shall
     constitute a binding irrevocable agreement by the Controlling Principals
     signing such notice and the Founders and Designated Purchasers named
     therein to purchase the Liberty Offered Shares at the Liberty Offer Price
     as provided in this Section 4. If a Founder

                                        8
<PAGE>

     Acceptance Notice meeting the requirements specified above is not delivered
     within the specified election period, then the Founders will be deemed to
     have rejected the offer of the Liberty Offered Shares.

     (b)  Upon delivery of a Founder Acceptance Notice meeting the requirements
     specified above within the specified election period, the Liberty Parties
     will be obligated to sell, and the Controlling Principals and the Founders
     and Designated Purchasers named in such Founder Acceptance Notice will be
     jointly and severally obligated to buy, all of the Liberty Offered Shares
     at the Liberty Offer Price. The closing of such purchase and sale shall
     occur at such time and place as the parties thereto may agree, but in any
     event no later than (i) the fifth Business Day after the Liberty Offer
     Notice is given, in the case of a Liberty Offer Notice with a Two-Business
     Day Election Period, or (ii) the 180th day after the Liberty Offer Notice
     is given, in the case of a Liberty Offer Notice with a Sixty-Day Election
     Period (each, an "Outside Closing Date"). The purchase and sale will be
     without representation or warranty, except that each party to the
     transaction will represent and warrant that it has all requisite power and
     authority to enter into the transactions, and the Liberty Parties
     transferring the shares will represent and warrant that they are
     transferring valid title to such shares and such shares are being
     transferred free and clear of any Lien or Restriction other than those
     created by this Agreement, any other Transaction Agreement or the parties
     taking delivery of such shares. Payment of the purchase price shall be in
     immediately available United States Dollars. A "Designated Purchaser" means
     any Person other than a Founder designated in a Founder Acceptance Notice
     as a purchaser of Liberty Offered Shares. As a condition to acquiring any
     Liberty Offered Shares pursuant to this Section 4, a Designated Purchaser
     must execute and deliver an instrument, in form and substance reasonably
     acceptable to United and the Liberty Parties, by which such Designated
     Purchaser agrees (i) to be subject to all of the obligations of a Founder
     Party under this Agreement and the Voting Agreement but, except for a
     Designated Purchaser that is a Permitted Transferee, to have none of the
     rights of a Founder Party hereunder or thereunder and (ii) in the case of a
     Designated Purchaser that is not a Permitted Transferee, to be subject to
     all of the obligations of a Liberty Party under the Standstill Agreement
     but to have none of the rights of a Liberty Party thereunder. Without
     limiting the generality of the foregoing, except for the imposition of the
     foregoing obligations on a Designated Purchaser, no Designated Purchaser
     that is not a Permitted Transferee will be considered a Founder Party for
     any purpose hereunder, including the termination provisions set forth in
     Section 13. Immediately following the Transfer of Liberty Offered Shares to
     a Founder or Designated Purchaser pursuant to this Section 4, such shares
     shall be converted to Class A Stock, or, if (i) then permissible under the
     United Charter, or (ii) such conversion would not result in a "Change of
     Control" pursuant to the Current Indentures as then in effect, Class B
     Stock, provided that if the Liberty Offered Shares are Class B Stock, such
     shares need not be converted into Class A Stock.

     (c)  If (i) the Founders reject or are deemed to reject the offer of the
     Liberty Offered Shares set forth in a Liberty Offer Notice, or (ii) the
     Founders accept such offer but the purchase and sale of all of the Liberty
     Offered Shares does not occur by the applicable Outside Closing Date for
     any reason other than the Liberty Parties' failure to comply with their
     respective obligations under Section 4(b), then the Liberty Parties shall
     be free to Transfer the Liberty Offered Shares (or, if applicable, convert
     the Liberty Offered Shares into shares of Class A Stock); provided that, in
     the case of a Transfer:

        (A)  such Liberty Offered Shares are converted into Class A Stock prior
        to the Transfer, and

        (B)  in the case of a Liberty Offer Notice with a Sixty-Day Election
        Period, the Transfer occurs at a price per share equal to or higher than
        the Liberty Offer Price within 60 days after the applicable of (x) the
        last day of the Sixty-Day Election Period, if the offer set forth in the
        Liberty Offer Notice was rejected or deemed rejected or (y) the
        applicable Outside Closing Date, if the closing of the sale of the
        Liberty Offered Shares pursuant to the Liberty Offer Notice did not
        occur by such date; or

                                        9
<PAGE>

        (C)  in the case of a Liberty Offer Notice with a Two-Business Day
        Election Period, the Transfer either occurs in accordance with Clause
        (B) above or, if the Liberty Offer Price specified in the applicable
        Liberty Offer Notice was the market price of the Class A Stock (or, if
        the Class B Stock is then publicly traded, the Class B Stock) at the
        time of such Liberty Offer Notice, the Transfer occurs at a price not
        less than the then current market price of the Class A Stock (whether
        higher or lower than the Liberty Offer Price) within 15 days after the
        applicable of (x) the last day of the Two-Business Day Election Period,
        if the offer set forth in the Liberty Offer Notice was rejected or
        deemed rejected or (y) the applicable Outside Closing Date, if the
        closing of the sale of the Liberty Offered Shares pursuant to the
        Liberty Offer Notice did not occur by such date.

Any purported Transfer of Subject Shares in violation of this Section 4 shall be
void and ineffective as against both the transferring Liberty Party and the
proposed transferee, and any purported conversion of Subject Shares in violation
of this Section 4 shall be void and ineffective.

SECTION 5.  Liberty Parties' Right of First Offer.

     (a)  No Founder Party shall Transfer any Subject Shares to any Person other
     than a Permitted Transferee in compliance with Section 6 or convert any
     Subject Shares to Class A Stock, unless, prior to such Transfer or
     conversion, such Founder Party first offers to sell the Subject Shares
     proposed to be Transferred or converted (the "Founder Offered Shares") to
     the Liberty Parties by delivering a written notice (a "Founder Offer
     Notice") to the Liberty Parties. The Founder Offer Notice shall state the
     number and class of Founder Offered Shares and the price per share (the
     "Founder Offer Price") at which such Founder Party is offering the Founder
     Offered Shares to the Liberty Parties and shall constitute a binding,
     irrevocable offer, subject to the provisions of this Section 5, to sell the
     Founder Offered Shares to the Liberty Parties at the Founder Offer Price.
     In order to accept the offer of the Founder Offered Shares, Liberty must
     deliver a written notice of acceptance (a "Liberty Acceptance Notice") to
     the offering Founder Party agreeing to purchase, or to cause another
     Liberty Party or a Permitted Transferee to purchase, all, but not less than
     all, of the Founder Offered Shares at the Founder Offer Price. In order to
     be effective, a Liberty Acceptance Notice must (i) be signed by Liberty and
     (ii) be delivered to the offering Founder Party no later than 5:00 p.m.
     Denver, Colorado time on the last day of the thirty day period (a "Founder
     Election Period") following the date the Founder Offer Notice is given. A
     duly completed and delivered Liberty Acceptance Notice shall constitute a
     binding irrevocable agreement by Liberty to purchase, or to cause another
     Liberty Party or a Permitted Transferee to purchase, the Founder Offered
     Shares at the Founder Offer Price as provided in this Section 5. If a
     Liberty Acceptance Notice meeting the requirements specified above is not
     delivered within the specified election period, then the Liberty Parties
     will be deemed to have rejected the offer of the Founder Offered Shares.

     (b)  Upon delivery of a Liberty Acceptance Notice meeting the requirements
     specified above within the specified election period, the offering Founder
     Party will be obligated to sell, and Liberty will be obligated to purchase,
     or to cause another Liberty Party or a Permitted Transferee to purchase,
     all of the Founder Offered Shares at the Founder Offer Price. The closing
     of such purchase and sale shall occur at such time and place as the parties
     thereto may agree, but in any event no later than the 60th day after the
     Founder Offer Notice is given (provided that such 60 day period may be
     extended for up to an additional 90 days to the extent that the acquisition
     of the Founder Offered Shares requires any Governmental Approval that has
     not been obtained during that period). The purchase and sale will be
     without representation or warranty, except that each party to the
     transaction will represent and warrant that it has all requisite power and
     authority to enter into the transactions, and the Founder Party
     transferring the shares will represent and warrant that it is transferring
     valid title to such shares and such shares are being transferred free and
     clear of any Lien or Restriction other than those created by this
     Agreement, any other Transaction Agreement or the parties taking delivery
     of such shares. Payment of the purchase price shall be in immediately
     available United States Dollars. As a condition to acquiring any Founder
     Offered Shares, a Permitted Transferee of a Liberty Party that is not then
     a party to this Agreement must execute and deliver an instrument, in form
     and substance

                                       10
<PAGE>

     reasonably acceptable to United and the Controlling Principals, by which
     such Permitted Transferee agrees to be subject to all of the rights and
     obligations of a Liberty Party under this Agreement and the Standstill
     Agreement.

     (c)  If (i) the Liberty Parties reject or are deemed to reject the offer of
     the Founder Offered Shares set forth in a Founder Offer Notice, or (ii) the
     Liberty Parties accept such offer but the purchase and sale of all of the
     Founder Offered Shares does not occur within the time period specified in
     Section 5(b) (as extended, if applicable, the "Liberty Purchase Period")
     for any reason other than the Founders' failure to comply with their
     respective obligations under Section 5(b), then the Founder Party
     delivering the Founder Offer Notice shall be free to Transfer the Founder
     Offered Shares (or, if applicable, convert the Founder Offered Shares into
     shares of Class A Stock), provided that, in the case of a Transfer:

        (A)  the Transfer occurs at a price per share equal to or higher than
        the Founder Offer Price within 60 days after the applicable of (x) the
        last day of the Founder Election Period if the offer set forth in the
        Founder Offer Notice was rejected or deemed rejected or (y) the last day
        of the Liberty Purchase Period if the closing of the sale of the Founder
        Offered Shares pursuant to the Founder Offer Notice did not occur by
        such date, and

        (B)  unless the aggregate number of Founder Offered Shares then being
        Transferred by all Founder Parties to the same transferee represents at
        least a majority of the aggregate amount of Subject Shares Beneficially
        Owned by all Founders and their Permitted Transferees and Designated
        Purchasers, such Founder Offered Shares are converted into shares of
        Class A Stock prior to the Transfer.

Any purported Transfer of Subject Shares in violation of this Section 5 shall be
void and ineffective as against both the transferring Founder Party and the
proposed transferee, and any purported conversion of Subject Shares in violation
of this Section 5 shall be void and ineffective.

SECTION 6.  Permitted Transfers.

     (a)  The Liberty Parties and any Founder Party may Transfer Subject Shares
     to their respective Permitted Transferees without being obligated to first
     deliver a First Offer Notice to any other party, provided that the
     Permitted Transferee undertakes in writing to be subject to each of the
     terms of this Agreement, and in the case of a Permitted Transferee of a
     Liberty Party, the Standstill Agreement and, in the case of Permitted
     Transferees of the Founder Parties, the Voting Agreement and is then
     subject to the rights and obligations that apply to the Liberty Parties, in
     the case of Permitted Transferees of a Liberty Party, or the Founder
     Parties, in the case of Permitted Transferees of a Founder Party. Any
     purported Transfer to a Permitted Transferee shall be void and ineffective
     as against both the transferring Liberty Party or Founder Party, and the
     Permitted Transferee, if the Permitted Transferee fails to become subject
     to this Agreement and subject to the rights and obligations of the
     transferring Liberty Party or Founder Party.

     (b)  A Founder Party or Liberty Party may pledge or grant a security
     interest in Subject Shares, or Rights to acquire Subject Shares, to a
     financial institution to secure a bona fide loan made to such Founder Party
     or Liberty Party, or in connection with a hedging transaction with a
     financial institution, without becoming obligated to deliver a First Offer
     Notice; provided that the lender or counter-party (i) may not become the
     registered holder of Subject Shares as a consequence thereof, (ii) agrees
     in writing with the pledging party (in an agreement which expressly
     provides that United and the non-pledging party (the Liberty Parties or the
     Founders, as applicable) are third-party beneficiaries thereof) that such
     secured party shall not foreclose upon or Transfer any Subject Shares
     pursuant to the exercise of its remedies with respect to such pledge or
     security interest unless it first complies with the provisions of Section 4
     as if it were a Liberty Party, in the case of a pledge of Subject Shares
     held by a Liberty Party, and the provisions of Section 5 as if it were a
     Founder Party, in the case of a pledge of Subject Shares held by a Founder
     Party, and, in either case, if the applicable offer is rejected or deemed
     rejected or the purchase and sale of the offered shares fail for

                                       11
<PAGE>

     any reason to occur, it converts the Subject Shares subject to such pledge
     or security interest into Class A Stock prior to such foreclosure or
     Transfer. Notwithstanding the foregoing reference to the provisions of
     Section 4 and 5, for pledges made to secure loans (or notional amounts in
     the case of hedging transactions) of less than $15 million, (1) the maximum
     election period shall be one (1) Business Day (rather than the Sixty-Day
     Election Period provided in Section 4 or the thirty-day Founder Election
     Period provided in Section 5) and (2) the closing of any purchase and sale
     of the pledged shares by the Liberty Parties or the Founders, as
     applicable, pursuant to the exercise of their first offer rights shall
     occur within three (3) Business Days of the delivery of a First Offer
     Notice by the secured party.

     (c)  Those pledges of common stock of Old United that were in effect on May
     25, 2001 and are identified on Appendix I hereto, and which apply to
     Subject Shares as of the date hereof, shall not be deemed to have been made
     in violation of the foregoing provisions of this Agreement, provided that
     the pledging parties use their best commercially reasonable efforts to
     obtain the agreement of the applicable lender or counter-party contemplated
     by Section 6(b).

SECTION 7.  Tag-Along Rights.

     (a)  If (i) (A) the Liberty Parties propose to Transfer Liberty Offered
     Shares representing a majority of the Class B and Class C Stock then
     Beneficially Owned by the Liberty Parties or, when taken together with all
     prior Transfers of such stock other than to a Permitted Transferee or the
     Founders and their Designated Purchasers, a number of shares equal to a
     majority of such stock Beneficially Owned by the Liberty Parties as of the
     date hereof, in either case pursuant to a Liberty Offer Notice or Liberty
     Offer Notices delivered in accordance with Section 4, (B) the Founders and
     their Designated Purchasers fail to purchase such Liberty Offered Shares
     and (C) the Liberty Parties propose to Transfer the Class A Stock obtained
     by the conversion of such Liberty Offered Shares to a Person other than a
     Permitted Transferee, or (ii) (A) the Founder Parties propose to Transfer
     Founder Offered Shares representing a majority of the Class B Stock then
     Beneficially Owned by all Founder Parties, or, when taken together with all
     prior Transfers of such stock other than to a Permitted Transferee or the
     Liberty Parties, a number of shares equal to a majority of such stock
     Beneficially Owned by the Founders and their Permitted Transferees as of
     the date hereof, in either case pursuant to a Founder Offer Notice or
     Founder Offer Notices delivered in accordance with Section 5, (B) the
     Liberty Parties fail to purchase such Founder Offered Shares and (C) the
     Founder Parties propose to Transfer such Founder Offered Shares to a Person
     other than a Permitted Transferee, the proposed transferor(s) (the
     "Transferor") must first deliver a notice (a "Tag-Along Notice") to the
     Founders, if the Transferor is one or more Liberty Parties, or to the
     Liberty Parties, if the Transferor is one or more Founder Parties, setting
     forth (w) the number of shares of Class A Stock or shares of Class B Stock
     proposed to be Transferred (which shall be the same as the number of
     Subject Shares subject to the applicable First Offer Notice), (x) the price
     per share of Class A Stock or per share of Class B Stock at which the
     shares of Class A Stock or shares of Class B Stock are proposed to be
     Transferred (which shall be equal to or greater than the price per share
     set forth in the applicable First Offer Notice), (y) all Liens and
     Restrictions to which the shares of Class A Stock or shares of Class B
     Stock proposed to be Transferred will be subject, and (z) whether the
     shares of Class A Stock or shares of Class B Stock proposed to be
     Transferred are to be sold for cash or other consideration and the other
     terms of the proposed Transfer.

     (b)  The Liberty Parties (if the Transferor is one or more Founder Parties)
     or the Founder Parties (if the Transferor is one or more Liberty Parties)
     (the applicable of the foregoing, the "Tag-Along Group") shall have the
     right (the "Tag-Along Right"), exercisable by written notice delivered to
     the Transferor not later than 15 Business Days following the date the
     Tag-Along Notice is given, to elect to Transfer up to an aggregate number
     of shares of Class B Stock and/or Class C Stock (and/or, if the Tag-Along
     Group consists of one or more Liberty Parties, Class A Stock) owned by the
     members of the Tag-Along Group equal to the number determined by
     multiplying the number of shares of Class B Stock (or Class A Stock if the
     Transferor is a Liberty Party) proposed to be transferred by the Transferor
     by a fraction the numerator of which is the number of shares of Class B
     Stock and

                                       12
<PAGE>

     Class C Stock (and, if the Tag-Along Group consists of one or more Liberty
     Parties, Class A Stock) then owned in the aggregate by the members of the
     Tag-Along Group and the denominator of which is the total number of shares
     of Class B Stock and Class C Stock then owned in the aggregate by the
     Transferor and the members of the Tag-Along Group (and, if the Tag-Along
     Group consists of one or more Liberty Parties, shares of Class A Stock then
     owned by members of the Tag-Along Group). The shares of Common Stock
     Transferred by the Liberty Parties pursuant to the exercise of a Tag-Along
     Right may include shares of Class A Stock, but only up to an aggregate
     number of shares of Class A Stock in any such Transfer equal to the number
     determined by multiplying the total number of shares of Common Stock that
     may be Transferred by the Liberty Parties pursuant to such Tag-Along Right
     (computed in accordance with the preceding sentence) by a fraction, the
     numerator of which is the number of shares of Class A Stock then owned in
     the aggregate by the Liberty Parties and the denominator of which is the
     total number of shares of Common Stock then owned in the aggregate by the
     Liberty Parties. The Tag-Along Right shall be allocated among the members
     of the Tag-Along Group by Liberty (in the case of the Liberty Parties) or
     the Controlling Principals (in the case of the Founder Parties). The number
     of shares to be Transferred by the Transferor shall be reduced by the
     number of shares to be sold by the parties to this Agreement that exercise
     Tag-Along Rights ("Exercising Holders").

     (c)  The terms on which any Transferor required to deliver a Tag-Along
     Notice actually Transfers its shares of Class B Stock or shares of Class A
     Stock shall not be more favorable, and shall include no more cash, than the
     terms on which Exercising Holders Transfer their shares of Common Stock.
     Exercising Holders may be required to make the same representations,
     warranties, covenants and agreements as are given by the Transferor in
     connection with any Transfer pursuant to this Section 7, but only insofar
     as they relate to such Exercising Holder's ownership of the Common Stock
     subject to the Transfer, are representations or warranties regarding the
     approval, authorization or enforceability of such action, or are covenants
     or agreements to the effect that such Exercising Holder will take such
     commercially reasonable actions as may be necessary for the Transfer to
     lawfully occur and which the Transferor has also agreed to take (other than
     any such actions which can reasonably be taken only by the Transferor).

If any Liberty Party or Founder Party exercises its Tag-Along Right, the
Transferor required to deliver a Tag-Along Notice shall cause the documents
relating to the Transfer of its shares of Class A Stock or shares of Class B
Stock to the proposed transferee to be amended so that such documents include as
parties the Exercising Holders, and so as to provide that the proposed
transferee shall acquire from such Exercising Holders the number of shares of
Common Stock held by such Exercising Holders as to which the Tag-Along Right has
been exercised. The closing of the sale of Common Stock by any Exercising Holder
pursuant to this Section 7 shall, to the extent legally practicable, take place
at the same time and place as the closing of the Transfer by any Transferor
giving rise to the Tag-Along Right. At such closing, (x) the Exercising Holders
shall deliver to the transferee certificates representing the Common Stock
subject to the Transfer, free and clear of any Lien or Restriction (if the
Transferor's shares are being transferred free and clear of any Lien or
Restriction) other than those created by this Agreement, another Transaction
Agreement, the Transferor or the transferee, (y) the transferee shall deliver to
the Exercising Holders the consideration to be paid for such Common Stock in
accordance with the terms of the purchase and sale of such Common Stock and of
the Common Stock of the Transferor, and (z) subject to the preceding paragraph,
the Exercising Holders shall execute such other documents and take such other
actions as are reasonably necessary to consummate the sale of such Common Stock
and are also being taken by the Transferor (other than any such actions as can
reasonably be taken only by the Transferor). Any shares of Class C Stock
Transferred to a transferee pursuant to this Section shall be converted
immediately prior to such Transfer to Class A Stock or, if then permissible
under the United Charter, Class B Stock.

Any purported Transfer of Common Stock in violation of this Section 7 shall be
void and ineffective as against both the Transferor and the proposed transferee.

SECTION 8.  Drag-Along Rights.

     (a)  If (A) the Founder Parties propose to Transfer Founder Offered Shares
     in an amount equal to the greater of (1) a number of shares that represents
     a majority of the Class B Stock then Beneficially Owned by all Founders and
     their Permitted Transferees or (2) a number of shares that, when taken
     together with all shares of Class B Stock previously Transferred to Persons
     other than Permitted Transferees or the Liberty Parties, represents a
     majority of the Class B Stock Beneficially Owned by the Founders and their
     Permitted Transferees as of the date hereof, in either case, pursuant to a
     Founder Offer Notice or Founder Offer Notices delivered in accordance with
     Section 5, (B) the Liberty Parties fail to purchase such Founder Offered
     Shares and (C) the Founder Parties propose to Transfer such Founder Offered
     Shares to an unaffiliated third party that is not a Permitted Transferee,
     then the Controlling Principals may deliver a notice (a "Drag-Along
     Notice") to the Liberty Parties setting forth (w) the number of shares of
     Class B Stock proposed to be Transferred (which shall be the same as the
     number of Subject Shares subject to the applicable Founder Offer Notice),
     (x) the price per share at which the shares of Class B Stock are proposed
     to be Transferred (which shall be equal to or greater than the price per
     share set forth in the applicable Founder Offer Notice), (y) all Liens and
     Restrictions to which the shares of Class B Stock proposed to be
     Transferred will be subject, and (z) whether the Class B Stock proposed to
     be Transferred is to be sold for cash or other consideration and the other
     terms of the proposed Transfer.

     (b)  Upon receipt of a Drag-Along Notice, the Liberty Parties will be
     required to Transfer to the proposed transferee, at the Liberty Parties'
     election, (i) all shares of Class B Stock and Class C Stock Beneficially
     Owned by the Liberty Parties as to which they have dispositive power, (ii)
     all shares of Common Stock Beneficially Owned by the Liberty Parties as to
     which they have dispositive power or (iii) the Proportionate Number of
     Shares Beneficially Owned by the Liberty Parties (and, in the case of a
     Transfer pursuant to this clause (iii), such Proportionate Number of Shares
     Beneficially Owned by the Liberty Parties shall be comprised of shares of
     Common Stock of each class in the same relative proportions as the Liberty
     Parties' aggregate Beneficial Ownership of each such class bears to the
     Liberty Parties' aggregate Beneficial Ownership of Common Stock of all
     classes); provided, however, that if, in connection with the proposed
     Transfer by the Founders, Mr. Gene W. Schneider, G. Schneider Holdings,
     Co., a Colorado limited partnership, The Gene W. Schneider Family Trust,
     Mr. Mark L. Schneider and The MLS Family Partnership LP propose to Transfer
     to the proposed transferee all shares of Common Stock Beneficially Owned by
     them, which shares of Common Stock include shares of Class B Stock
     representing at least 40% of the greater of (x) the number of shares of
     Class B Stock Beneficially Owned by them in the aggregate as of the date
     hereof and (y) the number of shares of Class B common stock of Old United
     Beneficially Owned by them in the aggregate as of June 25, 2000, in each
     case appropriately adjusted for stock splits, stock dividends and other
     similar events, then the Liberty Parties will be required to Transfer to
     the proposed transferee all shares of Common Stock Beneficially Owned by
     them as to which they have dispositive power.

     (c)  The Liberty Parties may require that any Transfer with respect to
     which the Founders exercise their Drag-Along Rights be structured as a
     transaction in which all holders of Class B Stock and Class C Stock are
     treated equally with respect to all shares of Common Stock being
     transferred and that is a tax-free transaction for the Liberty Parties.

     (d)  Upon exercise by the Founders of Drag-Along Rights, the terms on which
     the Liberty Parties actually Transfer their Common Stock shall not be less
     favorable, and (subject to clause (c) above) shall not include less cash,
     than the terms on which the Founder Parties Transfer their Class B Stock.
     The Liberty Parties may be required to make the same representations,
     warranties, covenants and agreements as are given by the Founder Parties in
     connection with any Transfer pursuant to this Section 8, but only insofar
     as they relate to the Liberty Parties' ownership of the Common Stock
     subject to the Transfer, are representations or warranties regarding
     approval, authorization or enforceability of such action, or are covenants
     or agreements to the effect that the Liberty Parties will take such
     commercially reasonable actions as may be necessary for the Transfer to
     lawfully occur and

                                       14
<PAGE>

     which the Founder Parties have also agreed to take (other than any such
     action which can reasonably be taken only by the Founders).

Upon exercise by the Founders of Drag-Along Rights, the Founders shall cause the
documents relating to the Transfer of their Class B Stock to the proposed
transferee to be amended so that such documents include as parties the Liberty
Parties, and so as to provide that the proposed transferee shall acquire from
the Liberty Parties the number of shares of Common Stock determined in
accordance with Section 8(b). Except as otherwise required in order to satisfy
Section 8(c), the closing of the sale of Common Stock by the Liberty Parties
pursuant to this Section 8 shall, to the extent legally practicable, take place
at the same time and place as the closing of the Transfer by the Founder
Parties. At such closing, (x) the Liberty Parties shall deliver to the
transferee certificates representing the Common Stock subject to the Transfer,
free and clear of any Lien or Restriction (if the Founder Parties' shares are
being transferred free and clear of any Lien or Restriction) other than those
created by this Agreement, any other Transaction Agreement or the transferee,
(y) the transferee shall deliver to the Liberty Parties the consideration to be
paid for such Common Stock in accordance with the terms of the purchase and sale
of such Common Stock and of the Class B Stock of the Founder Parties, and (z)
subject to the preceding paragraph, the Liberty Parties shall, to the same
extent as the Founder Parties with respect to the Class B Stock being
transferred by them, execute such other documents and take such other
commercially reasonable actions as may be necessary to consummate the sale of
such Common Stock (other than any such action which can reasonably be taken only
by the Founders). Any shares of Class C Stock Transferred to a transferee
pursuant to this Section 8 shall be converted immediately following such
Transfer to Class A Stock or, if (i) then permissible under the United Charter
or (ii) such conversion would not result in a "Change of Control" pursuant to
the Current Indentures as then in effect, Class B Stock.

SECTION 9.  All Shares.

All Equity Securities at any time Beneficially Owned by the Liberty Parties or
the Founders or any of their Permitted Transferees shall be subject to the terms
of this Agreement.

SECTION 10.  Exchange of Shares.

     (a)  United will, on request of Liberty and subject to applicable Law and
     listing requirements, permit any Liberty Party or its Affiliates to
     exchange any shares of Class A Stock or Class B Stock Beneficially Owned by
     such Liberty Party or Affiliate for shares of Class C Stock or, following
     the conversion of the Class C Stock, Class B Stock on a one-for-one basis.

     (b)  United will, on request of Liberty and subject to applicable Law and
     listing requirements, permit any Liberty Party or its Affiliates to
     exchange capital stock of UPC (or capital stock of any other Affiliate of
     United (including, for purposes of this Section 10, any Person in which
     United, directly or indirectly, Beneficially Owns 50% or more of the equity
     securities, without regard to voting power in the election of directors))
     Beneficially Owned by such Liberty Party or Affiliate (which shares were
     acquired from UPC or such Affiliate) for shares of Class C Stock or,
     following the conversion of the Class C Stock, Class B Stock on the basis
     provided in subsection (c) of this Section 10 and otherwise on such basis
     as Liberty and United may agree, including the receipt of required fairness
     opinions. United will use commercially reasonable efforts to structure any
     such exchange so that it is tax-free to Liberty.

     (c)  Without limiting the generality of the foregoing, at any time and from
     time to time after the occurrence of an event that, upon the giving of
     notice by UPC would entitle UPC to convert the shares of its Series 1
     Convertible Preference Shares A ("UPC Convertible Shares") Beneficially
     Owned by Liberty into ordinary shares of UPC ("UPC Ordinary Shares") (i)
     Liberty will have the right to put all or any portion of the UPC
     Convertible Shares or the UPC Ordinary Shares received on conversion or
     redemption of the UPC Convertible Shares or on exercise of warrants to
     United in exchange for shares of Class C Stock, or, following the
     conversion of the Class C Stock, Class B Stock, valued at the Agreed United
     Per Share Value (as defined in (and determined in accordance

                                       15
<PAGE>

     with) Schedule 10(c) to this Agreement, except that any values ascribed to
     United's direct or indirect investment in UPC Ordinary Shares and UPC
     Convertible Shares shall not exceed the values ascribed to such securities
     pursuant to the following sentence), and (ii) provided such exchange is
     tax-free to Liberty, United will have the right to call such UPC
     Convertible Shares or UPC Ordinary Shares from Liberty in exchange for
     shares of Class C Stock, or, following the conversion of the Class C Stock,
     Class B Stock, valued at the Average Market Price (as defined in the Merger
     Agreement) of the Class A Stock. For purposes of such put or call: (A) the
     value of UPC Convertible Shares will be as agreed by Liberty and United or,
     subject to Section 10(d), if they have not agreed on such value within ten
     days after the date notice of exercise of a put or call is given, as
     determined by an independent investment banking firm selected by the
     parties taking into account, among other things, the average closing sale
     price of the UPC Ordinary Shares for the period of 20 trading days
     preceding the date of such notice, and (B) UPC Ordinary Shares will be
     valued at the Average Market Price (as defined in the Merger Agreement) of
     the UPC Ordinary Shares as of the date notice of exercise of a put or call
     is given. If Liberty elects to exercise a put, United will use commercially
     reasonable efforts to structure the exchange transaction so that it is
     tax-free to Liberty.

     (d)  If Liberty and United are unable to agree on the value of UPC
     Convertible Shares and are unable to agree on the selection of an
     investment banking firm to make such determination within the ten day
     period provided in Section 10(c)(A), then either party may select such
     investment banking firm by delivering written notice of such selection to
     the other party at any time after the expiration of such ten day period;
     provided however, that if the party receiving such a notice, within ten
     days after the receipt thereof, delivers written notice to the other party
     designating an alternate investment banking firm, then the two investment
     banking firms identified by the parties shall select a third investment
     banking firm, which shall determine the value of the UPC Convertible Shares
     as contemplated by Section 10(c)(A).

SECTION 11.  Endorsement of Certificates.

     (a)  United shall endorse upon the certificate for each of the Equity
     Securities Beneficially Owned by the Liberty Parties and the Founders a
     legend substantially the same as the following legend:

        "The securities represented by this certificate are subject to a
        [Stockholders Agreement and a Standstill Agreement [in the case of such
        securities held by Liberty Parties]], a [Stockholders Agreement and a
        Voting Agreement [in the case of such securities held by Founders]],
        each dated as of                     , 2002, copies of which are
        available from UnitedGlobalCom, Inc. upon request, and any sale, pledge,
        hypothecation, transfer, assignment or other disposition of such
        securities is subject to such Stockholders Agreement and [Standstill
        Agreement] [Voting Agreement]."

     (b)  Upon surrender to United of any certificate representing any Equity
     Securities or Rights disposed of by a Liberty Party or any Affiliate of a
     Liberty Party in a transaction described in Section 5(a)(ii) or (v) of the
     Standstill Agreement or in clause (ii), (iii) or (iv) of the definition of
     Transfer in Section 1, United shall promptly cause to be issued (i) to the
     transferee or transferees of such Equity Securities or Rights one or more
     certificates without the legend set forth in Section 11(a) and (ii) to the
     holder of Equity Securities or Rights represented by such certificates so
     surrendered one or more certificates representing such Equity Securities or
     Rights, if any, as shall not have been so disposed of, with the legend set
     forth in Section 11(a). Upon termination of this Agreement pursuant to
     Section 13 and the surrender to United of any certificate representing
     Equity Securities or Rights, United shall cause to be issued to the holder
     of such Equity Securities or Rights one or more certificates without the
     legend set forth in Section 11(a).

                                       16

SECTION 12.  Representations and Warranties.

Each of the Liberty Parties, on the one hand, and the Founders and United, on
the other, severally and not jointly, represent and warrant to each other as of
the date of this Agreement as follows:

     (a)  Such party has the right, power, legal capacity and authority to enter
     into and perform such party's obligations under this Agreement, and this
     Agreement constitutes such party's valid and binding obligation,
     enforceable against such party in accordance with its terms, subject, as to
     enforceability, to applicable bankruptcy, insolvency, fraudulent
     conveyance, reorganization, moratorium and similar laws affecting
     creditor's rights and remedies generally, and to general principles of
     equity, including principles of commercial reasonableness, good faith and
     fair dealing (regardless of whether enforcement is sought in a proceeding
     at law or in equity).

     (b)  Such party has obtained all authorizations, permits, approvals or
     consents of any Persons, as well as all authorizations, permits, approvals
     or consents of any Governmental Authorities, necessary to enter into and
     perform such party's obligations under this Agreement, except as would not,
     individually or in the aggregate, materially adversely affect such party's
     ability to perform its obligations under this Agreement.

     (c)  Such party is the lawful and Beneficial Owner of record of the Equity
     Securities set forth opposite such party's name in Appendix I, free and
     clear of any Lien or Restriction, except for those created by this
     Agreement or any other Transaction Agreement, or as otherwise set forth in
     Appendix I. In the case of a Founder, the number of equity securities of
     Old United Beneficially Owned by such party as of June 25, 2000 is also set
     forth on Appendix I.(1)

     (d)  This Agreement and the transactions it contemplates do not conflict
     with any applicable Law or any agreement to which such party is a party or
     constitute a default under any such agreement, except as would not,
     individually or in the aggregate, materially adversely affect such party's
     ability to perform its obligations under this Agreement.

SECTION 13.  Term and Termination.

     (a) The Liberty Parties' covenants set forth in Section 3(a), the parties'

1.  The "Agreed United Per Share Value" for purposes of Section 10(c) of the
Agreement shall be equal to the SOP Value of United, determined in accordance
with the terms of the following paragraphs.

2.  Promptly following the date notice is given of the exercise of a put
pursuant to Section 10(c), Liberty and United shall negotiate in good faith to
determine the SOP Value of United.

3.  (a) If within ten days following the date notice of an exercise of a put
pursuant to Section 10(c) is given (or such longer period as Liberty and United
may agree) Liberty and United have not agreed upon the SOP Value of United, the
determination of such SOP Value shall be determined in accordance with the
appraisal procedures set forth in this paragraph 3.

(b)  No later than the fifteenth day after the expiration of the ten-day (or
longer) period referred to in paragraph 3(a) (the "Selection Date"), Liberty and
United shall each notify the other of the nationally recognized investment
banking firm (an "Appraiser") selected by it to determine the SOP Value of
United (unless prior thereto the parties have jointly selected an Appraiser). If
either party fails to select or timely notify the other party of its selection
of an Appraiser, then the determination of the SOP Value of United shall be made
by the Appraiser selected by the other party. Each Appraiser shall deliver a
written report (the "Appraisal Report") to Liberty and United setting forth such
Appraiser's determination of the SOP Value of United within 20 days of the
Selection Date.

(c)  If there is only one Appraiser, the SOP Value of United shall be deemed to
be the SOP Value as determined by such Appraiser. If there are two Appraisers,
and if the higher of the Appraisers' respective determinations of such SOP Value
is not more than 120% of the lower of such determinations, then the SOP Value of
United shall be equal to the average of such two determinations. If the higher
of the respective determinations of such SOP Value is more than 120% of the
lower of such determinations, then the two Appraisers shall jointly select a
third Appraiser within five days following the date on which the last of the two
Appraisal Reports was delivered, and each such Appraiser shall furnish the third
Appraiser with its work product used in preparing its Appraisal Report;
provided, however, that if the first two Appraisers have not selected the third
Appraiser within 10 days, either Liberty or United may cause the American
Arbitration Association of New York to appoint such third Appraiser. Such third
Appraiser shall deliver its Appraisal Report of its determination of the SOP
Value of United within 20 days of its appointment, and in such case such SOP
Value shall be equal to the average of the two closest determinations; provided,
however, that if the difference between the highest and middle determinations is
no more than 105% and no less than 95% of the difference between the middle and
lowest determinations, then the SOP Value of United shall be equal to such
middle determination. For these purposes, if any such Appraiser expresses its
determination of the SOP Value of United as a range of values, such Appraiser's
determination of such SOP Value shall be deemed to be the midpoint of such range
of values. The determination of the SOP Value of United in accordance with the
provisions of this Schedule 10(c) shall be final, binding and conclusive, in the
absence of manifest error.

(d)  Each of Liberty and United shall use its commercially reasonable efforts to
cause its designated Appraiser to timely deliver its Appraisal Report, If,
pursuant to the foregoing procedures, a third determination is required, each of
Liberty and United shall use its commercially reasonable efforts to cause its
designated Appraiser to promptly take all actions necessary for the joint
selection by such two Appraisers of the third Appraiser and to promptly make
available to such third Appraiser the work product of such Appraiser relating to
its determination of the SOP Value of United and shall also take all reasonable
actions that are necessary in order to cause such third Appraiser to timely
deliver its Appraisal Report.

(e)  All fees and expenses of any Appraiser conducting an appraisal in
accordance with this Schedule 10(c) shall be paid by the party or parties
retaining such Appraiser. If a single Appraiser or a third Appraiser is retained
pursuant to this Schedule 10(c), the fees and expenses of such Appraiser shall
be split equally between Liberty and United.

<PAGE>

4.  For purposes of this Schedule 10(c), the "SOP Value" of United shall be
equal to a sum-of-the-parts valuation of such Person on a per share basis. For
purposes of such sum-of-the-parts valuation (i) any publicly traded capital
stock held by United, directly or indirectly through a wholly-owned Subsidiary
(as defined in the Merger Agreement), shall be deemed to have a value equal to
the Average Market Price (as defined in the Merger Agreement) of such capital
stock on the relevant date of determination and (ii) any non-publicly traded
interest in any business held by United (a "Non-Public Interest") shall be
deemed to have a value equal to the price (on an equity-value basis and net of
taxes if a taxable sale is assumed), on the relevant date of determination, that
a willing buyer having full knowledge of all relevant facts would pay to buy
such Non-Public Interest in a single arm's-length transaction in which neither
party is under any compulsion to sell or buy and no other consideration is paid
or business relationships entered into.

SECTION 2.  Certain Covenants.

     (a)  Without limitation of any other applicable provision hereof or of any
     other Transaction Agreement, without the prior written consent of Liberty,
     which consent may be granted or withheld in Liberty's sole discretion, Old
     United will not take any action and will not permit any action to be taken
     on its behalf, and will use its best commercially reasonable efforts to
     prevent any action from being taken by or on behalf of any of its
     Affiliates, that would result in New United, Old United or any of their
     respective Affiliates being subject to or bound by any Change of Control
     Covenant, unless any Change of Control involving or caused by the action of
     Liberty, Liberty Global, LMI or any of their respective Affiliates (other
     than a transfer by any of the foregoing to an unaffiliated third party of
     Control of New United, if such Control is obtained in the future) is
     exempted from the application and effects of such Change of Control
     Covenant. Old United will not be deemed to be in breach of the foregoing as
     a result of its or its Affiliates entering into or maintaining in the
     ordinary course of business a License granted by a Governmental Authority
     that includes a Change of Control Covenant provided that (i) such License
     is of the kind and nature that customarily requires approval of the
     Governmental Authority granting the same for a Change of Control, (ii) the
     applicable Change of Control Covenant includes only terms customarily
     imposed by such Governmental Authority in similar circumstances, (iii) the
     maximum penalty for breach of such Change of Control Covenant is
     termination of the applicable License, and (iv) Old United used its best
     commercially reasonable efforts to obtain the exemption from the
     application and effects of such Change of Control Covenant contemplated by
     the preceding sentence. Without the prior written consent of Liberty, which
     consent may be granted or withheld in Liberty's sole discretion, Old United
     will not take any action or permit any action to be taken that would, or
     fail to take any action or permit any action to be omitted where such
     failure or omission would, extend or perpetuate the applicability of any
     Change of Control Covenant in effect as of May 25, 2001 under the Current
     Bonds beyond the maturity date in effect as of May 25, 2001 of the Current
     Bonds to which they relate. Old United will use its best commercially
     reasonable efforts to take such actions as will cause the conditions
     necessary to permit the conversion in full of the New United Class C Stock
     into New United Class B Stock to be satisfied.

                                        4
<PAGE>

     (b)  Without limitation of any other applicable provision hereof or of any
     other Transaction Agreement, without the prior written consent of Liberty,
     Old United shall not, and shall not permit any of its Controlled Affiliates
     to, (i) (A) enter into, or issue, assume or adopt, any Contract that would
     be or that purports to be binding upon Liberty or any of its Affiliates or
     any of their respective assets, or (B) enter into, or issue, assume or
     adopt, any material Contract in respect of which any act or omission of
     Liberty or any of its Affiliates would result in a violation or breach
     thereof, or constitute (with or without due notice or lapse of time or
     both), or permit any Person to declare, a default or event of default
     thereunder, or give rise to any right of termination, cancellation,
     amendment, acceleration, repurchase, prepayment or repayment or to
     increased payments thereunder, or give rise to or accelerate any material
     obligation (including, without limitation, any obligation to, or to offer
     to, repurchase, prepay, repay or make increased payments) or result in the
     loss or modification of any material rights or benefits thereunder, or
     result in any Lien or Restriction on any of the material assets of, or
     otherwise have any adverse effect on, Old United or any of its Affiliates,
     or (ii) amend or modify any Contract described in clause (i) of this
     sentence; provided however, that this Section 2(b) shall not restrict Old
     United from subjecting itself or any of its Controlled Affiliates to a
     Change of Control Covenant to the extent permitted under Section 2(a).

SECTION 3.  Termination.  This Agreement shall terminate as to any Liberty Party
the voting power of whose Beneficially Owned Equity Securities (together with
that of its Permitted Transferees and Controlled Affiliates) is reduced to 10%
or less of the voting power of equity securities in Old United that such Liberty
Party (together with its Permitted Transferees and Controlled Affiliates)
Beneficially Owned as of June 25, 2000. For purposes of this Section 3, the
voting power of outstanding shares of New United Class C Stock, if any, shall be
calculated as if such shares had been converted into shares of New United Class
B Stock.

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 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 may 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.  Notices.  All notices and other communications hereunder shall be
delivered to the parties hereto in the same manner as set forth in the Merger
Agreement.

SECTION 8.  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 9.  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 except in a writing signed by all parties.

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 be followed by "without

                                       5

limitation" whether or not they are in fact followed by such words or words of

include the corresponding masculine, feminine and neuter forms; the singular
includes the plural and vice versa; references to any agreement or other

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.  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 13.  Parties in Interest.  Nothing in this Agreement, express or
implied, is intended to confer upon any Person other than the parties hereto,
their Permitted Transferees, in the case of the Liberty Parties, and their
permitted successors and assigns, any benefits, rights or remedies. Neither this
Agreement nor the rights or obligations of any party may be assigned or

Transferee) by operation of law or otherwise without the prior written consent
of Liberty and Old United. Notwithstanding the foregoing, any Person that
succeeds to Liberty's rights and obligations under the Stockholders Agreement
and the Standstill Agreement shall be entitled, as an express third party
beneficiary, to all of the rights of Liberty hereunder to the same extent as if
all references to Liberty herein referred to such Person.

        Liberty), and (B) cause the auditors of any such 3-09 Person to provide
        to Liberty such auditors' written consent to the inclusion of or

        such auditors in connection with the delivery of their consent to
        Liberty and timely provision by Liberty to such other auditors of
        preliminary versions of such filing. The determination as to whether a
        Person qualifies as a 3-09 Person shall be made in the reasonable
        judgment of Liberty and its auditors.

        (vi)  United shall not effect any acquisition, merger, exchange or other
        transaction pursuant to which United would acquire a Person that would

        statements prepared in accordance with GAAP that comply in all respects
        with Regulation S-X, including, without limitation, Rule 3-05 of
        Regulation S-X.

        (vii)  United shall, and shall use its best efforts to cause each 3-09

        auditors, books and records and furnish promptly to such Liberty Persons
        such financial and operating data and other information concerning its
        business, properties, personnel and affairs as such Liberty Persons will
        from time to time reasonably request and instruct the officers,
        directors, employees, counsel and auditors of United and each 3-09
        Person to discuss business operations, affairs and assets of United and
        each 3-09 Person and otherwise fully cooperate with each Liberty Person
        in its review of the business and financial affairs of United and each
        3-09 Person, in each case to the extent reasonably necessary to enable
        Liberty to comply timely with its reporting obligations under the
        Exchange Act. In addition, if at any time Liberty and its auditors, in
        their reasonable judgment, determine that the financial statements of
        United or any 3-09 Person (any such Person, a "Non-Complying Person")
        were not prepared in accordance with GAAP, do not

                                        6

        Non-Complying Person to (A) suspend the services of its current auditors
        and (B) afford to the Liberty Persons access to all books, records and

     Securities to be counted for quorum purposes. Except for (A) those matters

                                       6
<PAGE>

     pursuant to this Agreement, the Stockholders Agreement or the United

     Agreement, is required to be approved by Liberty, if such approval has not

     is required to be reviewed, voted upon and approved by the Board or a
     committee thereof, if such matter has not been reviewed, voted upon and
     approved by the required vote of the Board or a committee thereof, in any
     such case prior to the time such matter is presented to the stockholders of
     United for their approval, each Liberty Party will vote its Common Stock
     (i) with respect to any matter submitted for approval of stockholders of
     United (other than those referred to in clauses (ii) and (iii) below), in
     such Liberty Party's sole discretion, either (x) in the manner recommended
     by a majority of the Board or (y) in the same proportion as the holders of
     the remaining Common Stock vote with respect to such matter, (ii) against
     any merger, consolidation, recapitalization, dissolution or sale of all or
     substantially all of the assets of United not approved by the Board, and
     (iii) with respect to the election or removal of directors (x) following
     the occurrence of a Class B Event, as provided in Section 3(b) below, and
     (y) otherwise, in its sole discretion. Notwithstanding the foregoing, the
     Liberty Parties will be entitled to vote their Common Stock in favor of any
     proposal to approve or necessary to implement the transactions expressly
     contemplated by the Transaction Agreements, whether or not approval is
     recommended by the Board. No Liberty Party will exercise appraisal rights
     as to any matter.

     (b)  Following the occurrence of a Class B Event,

        (i)  The Liberty Parties shall have the right to nominate four members
        of the Board or, if greater, such number of members of the Board
        (rounded up to the next whole number) equal to 33 1/3% of the
        then-authorized number of members of the Board (each such nominee, a
        "Liberty Director"); pursuant to the Voting Agreement, the Controlling
        Principals will have the right to nominate four members of the Board or,
        if greater, such number of members of the Board (rounded up to the next
        whole number) equal to 33 1/3% of the then-authorized number of members
        of the Board (each such nominee, a "Controlling Principal Director");
        and the Board will nominate the remaining members of the Board.

        (ii)  The Liberty Parties will vote or cause to be voted all Equity
        Securities owned by them (or with respect to which they have the right
        to vote or direct the voting) that have the right to vote generally in
        the election of directors for the election to the Board of those persons
        nominated in accordance with this Section 3(b) and Section 3(c) and will
        not seek the removal of any director (other than a Liberty Director)
        except for cause; provided that, if the Controlling Principals request
        that the Liberty Parties vote in favor of the removal of any Controlling
        Principal Director, the Liberty Parties will vote or cause to be voted
        all Equity Securities owned by them (or with respect to which they have
        the right to vote or direct the voting) that have the right to vote on
        such matter in favor of the removal of such Controlling Principal
        Director.

        (iii)  The approval of the Liberty Directors shall be required for all
        matters set forth in paragraph (b) of Article Fifth of the United
        Charter as in effect on the date hereof, without regard to any
        limitation that would otherwise apply as a result of the Class C Stock
        ceasing to be outstanding.

     (c)  United shall take all necessary or desirable action (including,
     without limitation, nominating the Liberty Directors) in order to cause the
     Board to have the constituency provided for in Section 3(b) and to give
     effect to this Section 3. In the absence of any nomination by the Liberty
     Parties of a Liberty Director, the person or persons previously nominated
     by the Liberty Parties and then serving shall be re-nominated if still
     eligible to serve as provided herein. The Liberty Parties may request, and
     vote in favor of, the removal of any Liberty Director, with or without
     cause. The Liberty Parties will have the right to nominate a person to fill
     any vacancy on the Board created by the resignation, removal, incapacity or
     death of any Liberty Director. Pursuant to the Voting Agreement, the
     Controlling Principals will have the right to nominate a person to fill any
     vacancy on the Board created by the resignation, removal, incapacity or
     death of any Controlling Principal Director.

SECTION 4.  Certain United Covenants.

     (a)  If any consents, approvals, waivers or other action by, or notices to,
     filings with or applications or submissions to, any Governmental Authority
     or other third party are needed for any Liberty Party or any Controlled
     Affiliate of a Liberty Party to exercise any rights under this Agreement,
     any other Transaction Agreement or the United Charter (including the
     purchase rights and approval rights of the holders of Class C Stock set
     forth therein) or for the exercise of the approval rights of the Class C
     Directors or Liberty Directors under the United Charter, this Agreement and
     the New United Covenant Agreement, respectively, United shall cooperate
     with Liberty and use its best commercially reasonable efforts to obtain and
     assist Liberty in obtaining the necessary consents, approvals, waivers and
     other actions, and making the necessary notices, filings, applications and
     submissions.

     (b)  United will not issue, grant or sell any shares of Class B Stock, any
     Equity Securities convertible into or exercisable or exchangeable for Class
     B Stock (contingently or otherwise) or that have a greater vote per share
     (on an as-converted basis or otherwise) than the Class A Stock (whether
     generally, in the election of directors or generally other than in the
     election of directors) (collectively, "High-Vote Securities") or any Rights
     to acquire any of the foregoing, other than to a Liberty Party or
     Controlled Affiliate thereof, unless and until the Class C Stock has become
     convertible in full into Class B Stock, except that (x) United may issue up
     to an aggregate of three million shares of Class B Stock upon exercise of
     Assumed Options and Permitted Options, and (y) United may, on majority vote
     of the Board and compliance with applicable legal requirements, issue
     shares of a series of its preferred stock convertible into Class B Stock,
     but with no other conversion rights, no voting rights other than the
     limited voting rights customary in preferred stocks, and no other special
     rights, provided that such convertible preferred stock shall not be
     convertible into Class B Stock until the Class C Stock has become fully
     convertible into Class B Stock, and the aggregate number of shares of Class
     B Stock issuable upon conversion of all such preferred stock and the
     exercise of the Assumed Options and the Permitted Options shall be less
     than the number of shares that, if issued in one or more transactions
     following the occurrence of a Conversion Event, would entitle the Liberty
     Parties to exercise the purchase rights set forth in Section 7A (it being
     understood that such issuances will be taken into account in determining
     the Liberty Parties' entitlement to exercise such purchase rights).

     (c)  United will not issue, grant or sell any options exercisable for Class
     B Stock other than the Permitted Options without Liberty's prior consent.

SECTION 5.  Dispositions of Equity Securities.

     (a)  No Liberty Party shall Transfer or permit any of its Controlled
     Affiliates to Transfer Beneficial Ownership of any Equity Securities,
     unless the Transfer is (i) a Transfer to Liberty or a Controlled Affiliate
     of Liberty that is or becomes a party to this Agreement in accordance with
     Section 2(c); (ii) a Transfer of Class A Stock to one or more underwriters
     in connection with a bona fide public offering registered under the
     Securities Act; (iii) a Transfer to a Founder or Designated Purchaser
     pursuant to Section 4 of the Stockholders Agreement, provided that the
     transferee, if other than a Founder, delivers to United an undertaking to
     be bound by all provisions of the Stockholders Agreement and, in the case
     of a Designated Purchaser that is not a Permitted Transferee, this
     Agreement; (iv) a Transfer pursuant to Section 7 or 8 of the Stockholders
     Agreement; or (v) a Transfer of Class A Stock that otherwise complies with
     the terms of the Stockholders Agreement, provided that, in the case of a
     Transfer pursuant to clause (ii) or this clause (v) other than to an
     Affiliate, the transferring Liberty Party has no reason to believe that any
     Person or Group would hold as a result of such a Transfer of Beneficial
     Ownership more than ten percent of the Voting Power in the election of
     directors as of the date of such Transfer.

     (b)  The Liberty Parties may pledge or grant a security interest in Equity
     Securities to a financial institution to secure a bona fide loan made to a
     Liberty Party or in connection with a hedging

                                        8
<PAGE>

     transaction with a financial institution, so long as the Liberty Party
     complies with Section 6(b) of the Stockholders Agreement.

     (c)  Any attempted Transfer in violation of this Agreement shall be void.

SECTION 6.  Offers for United.

     (a)  If any Person shall make an offer (an "Offer"): (i) to acquire from
     United or from one or more stockholders thereof (by tender or exchange
     offer or other public offer), or both (the "Offeree"), Equity Securities of
     United, (ii) to acquire all, or substantially all, the assets of United, or
     (iii) to effect a merger, consolidation, statutory share exchange or
     similar transaction between or involving United and another Person, then
     United shall give Liberty notice of such Offer promptly upon receipt by
     United thereof or, if such disclosure of the existence or terms of such
     Offer is prohibited by the terms thereof or if counsel for United
     determines that such disclosure prior to a public announcement of such
     Offer may violate or result in the violation of applicable United States
     securities laws, promptly after the public announcement of such Offer. In
     no event will United give Liberty notice of such Offer less than ten days
     prior to acceptance of such Offer.

     (b)  If any such Offer is made or proposed to an Offeree and not rejected
     within five days, any Liberty Party or an Affiliate thereof may propose a
     competing offer to the Board and the Board shall in the exercise of its
     fiduciary duties consider in good faith waiving any provisions of this
     Agreement that would restrict actions that might be taken by a Liberty
     Party or its Affiliates in support of such competing offer or the
     transactions contemplated thereby.

     (c)  If United proposes (a "Proposal") to effect a sale of all or
     substantially all of the assets of United or a merger, consolidation,
     statutory share exchange or similar transaction between or involving United
     and another Person or to issue in any transaction Class B Stock in an
     amount such that the Liberty Parties' purchase rights would not apply to
     such issuance (whether as a result of clause (h)(ii) of Article Fourth of
     the United Charter or Section 7A(d) of this Agreement), then United shall
     give Liberty notice of such Proposal and, prior to taking any action to
     effectuate the same, United shall give Liberty the opportunity to propose
     (or to cause an Affiliate of Liberty to propose) an alternative transaction
     to the Board. If Liberty or an Affiliate thereof proposes an alternative
     transaction to the Proposal to the Board, the Board shall in the exercise
     of its fiduciary duties consider in good faith waiving any provisions of
     this Agreement that would restrict actions that might be taken by Liberty
     or its Affiliates in support of such alternative transaction.

     (d)  United shall not enter into any agreement or make any covenant that
     would preclude it from complying with this Section 6.

SECTION 7A.  Purchase Rights -- High-Vote Securities.

     (a)  If, following the occurrence of a Conversion Event, United issues,
     grants or sells any High-Vote Securities (including upon conversion,
     exercise or exchange of previously issued Rights) and after giving effect
     thereto, together with any prior issuances of Class B Stock with respect to
     which the Liberty Parties did not have any purchase rights pursuant to this
     Section 7A, including any issuance of Class B Stock or other High-Vote
     Securities contemplated by Section 4(b) (which issuance for purposes of
     this Section 7A shall be deemed to have occurred as of the later of the
     actual issuance of such Class B Stock or other High-Vote Securities and
     immediately after the occurrence of a Conversion Event), the combined
     voting power (whether in the election of directors or otherwise) of the
     Liberty Parties' Equity Securities is equal to or less than 90% of the
     combined voting power thereof immediately prior to either such issuance or
     the first such issuance (or deemed issuance), the Liberty Parties will be
     entitled, subject to applicable legal requirements (which United will use
     its best commercially reasonable efforts to cause to be satisfied or
     waived), to acquire from United additional shares of Class B Stock, in the
     manner provided in this Section 7A, in an amount sufficient to restore the
     combined voting power of the Equity Securities owned by the Liberty Parties
     to 100% of the combined voting power of the Liberty Parties' Equity
     Securities immediately prior to either such issuance or the first such
     issuance or deemed issuance (whichever is greater, in the case of

                                       9
<PAGE>

     multiple issuances) (appropriately adjusted for other acquisitions or
     dispositions of Equity Securities by the Liberty Parties following such
     first issuance or deemed issuances). For purposes of this Section 7A, the
     voting power of the Liberty Parties' Equity Securities shall in all cases
     be calculated as if any High-Vote Securities that are convertible into, or
     exercisable or exchangeable for, Class B Stock had been converted into or
     exercised or exchanged for Class B Stock.

     (b)  The Liberty Parties will be entitled to restore their voting power in
     United as provided above by, at their election:

        (i)  subject to applicable Law and listing requirements, surrendering
        shares of Class A Stock in exchange for Class B Stock on a one-for-one
        basis;

        (ii)  purchasing from United additional shares of Class B Stock for a
        purchase price per share, payable in cash or such other form of
        consideration as may be acceptable to United, equal to (x) the issue
        price per share of the Class B Stock equivalent of the High-Vote
        Securities so issued (which if paid other than in cash or shares of
        Class A Stock shall be the fair market value of the consideration so
        paid) or (y) with respect to any High-Vote Securities that were issued
        in exchange for shares of Class A Stock, the average of the Closing
        Prices (as defined in the United Charter as in effect on the date
        hereof) per share of the Class A Stock for the ten consecutive trading
        days preceding (A) the date on which the additional shares of Class B
        Stock are purchased or (B) the date on which such High-Vote Securities
        were issued, whichever yields the lower price, in each case
        appropriately adjusted to reflect the effect of any stock splits,
        reverse splits, combination, stock dividends or other events affecting
        the Class B Stock; or

        (iii)  any combination of the foregoing.

     (c)  If the Liberty Parties become entitled to acquire additional Class B
     Stock by purchase or exchange pursuant to the purchase rights contemplated
     by this Section 7A, United shall provide notice of such entitlement to
     Liberty within five Business Days after the issuance of any High-Vote
     Securities that alone or together with any prior issuances has reduced the
     voting power of the Liberty Parties' Equity Securities by ten percent or
     more. The right of the Liberty Parties to acquire additional Class B Stock
     shall then be contingent upon Liberty's (i) delivering a notice to United
     within ten days after receipt of United's notice, in which notice Liberty
     states that it or one or more other Liberty Parties or Controlled
     Affiliates will acquire additional Class B Stock pursuant to its purchase
     rights, and (ii) tendering the applicable consideration for such additional
     Class B Stock within 30 days after the later of receipt by Liberty of
     United's notice and the date of the issuance of High-Vote Securities that
     has reduced the voting power of the Liberty Parties' Equity Securities by
     ten percent or more (subject to extension for up to 60 additional days if
     required to obtain Governmental Approval or for any applicable waiting
     periods to expire or terminate).

     (d)  Notwithstanding the foregoing, if United issues Class B Stock in any
     transaction in an amount such that, immediately following such issuance,
     the Persons who were holders of outstanding Equity Securities immediately
     prior to such issuance of Class B Stock then hold in the aggregate less
     than 30 percent of the voting power of United's outstanding Equity
     Securities in the election of directors generally, then the Liberty Parties
     will not have a right to restore or maintain their voting power in United
     pursuant to such purchase rights.

SECTION 7B.  Preemptive Rights -- Class A Securities.

     (a)  If at any time after the execution and delivery of this Agreement
     United issues, grants or sells any Class A Securities, the Liberty Parties
     shall have the right, subject to applicable legal requirements (which
     United will use its best commercially reasonable efforts to cause to be
     satisfied or waived), but not the obligation, to acquire from United a
     portion of such Class A Securities up to an amount sufficient to permit the
     Liberty Parties to maintain the percentage of the total outstanding Common
     Stock represented by the Liberty Parties' Equity Securities immediately
     prior to the issuance of such Class A Securities, assuming for purposes of
     calculating such percentage that all Rights, if any, constituting Class A
     Securities held by the Liberty Parties or to be issued, granted or

                                       10
<PAGE>

     sold in such transaction have been duly converted, exchanged or exercised
     in full (whether or not then convertible, exchangeable or exercisable). If
     United desires to issue any Class A Securities, it will first give written
     notice (an "Issuance Notice") thereof to the Liberty Parties stating the
     number of Class A Securities proposed to be issued, granted or sold, the
     date such Class A Securities are proposed to be issued, granted or sold
     (which date shall be no more than 60 days nor less than 20 days after the
     date such Issuance Notice is delivered to Liberty), the total per share
     consideration to be received by United upon issue, grant or sale of such
     Class A Securities (which consideration may, in the case of an underwritten
     public offering for cash of Class A Stock or Rights convertible into or
     exchangeable or exercisable for Class A Stock, may be expressed as a range
     of per share prices (provided that such range shall be no more than the
     lesser of (A) 50% of the lowest price in such range and (B) $5 per share))
     and any other material terms of the proposed transaction. Within 20 days
     following receipt of an Issuance Notice, any Liberty Party may exercise its
     rights under this Section 7B by giving written notice (a "Preemption
     Notice") to that effect to United, which notice shall specify the maximum
     number of Class A Securities that such Liberty Party elects to purchase.
     Failure to deliver a Preemption Notice within such 20 day period will
     constitute a waiver of the rights granted by this Section 7B as to the
     particular issuance of Class A Securities specified in the Issuance Notice.

     (b)  The per share price to be paid upon exercise of the rights granted
     under this Section 7B with respect to any issuance, grant or sale of Class
     A Securities shall be the lower of the lowest per share consideration at
     which Class A Securities are issued, granted or sold in such issuance and
     the consideration per share specified in the applicable Issuance Notice.
     The consideration for which Class A Securities are offered or proposed to
     be offered will be determined as follows: (i) in case of the proposed
     issuance of Class A Securities for cash, the consideration per share will
     be the amount of cash per share to be received by United after any
     underwriting discounts and (ii) in the case of a proposed issuance of Class
     A Securities in whole or in part for consideration other than cash, the
     value of the consideration other than cash will be the fair market value of
     that consideration. The purchase price shall be payable in cash or such
     other form of consideration as may be reasonably acceptable to United, in
     an amount equal to the price per share of the Class A Securities so issued
     (which if paid other than in cash shall be the fair market value of the
     consideration so paid).

     (c)  Upon delivery of a Preemption Notice in accordance with Section 7B(a),
     United and the Liberty Parties delivering such Preemption Notice will enter
     into a purchase and sale agreement pursuant to which United will be
     obligated to sell and such Liberty Parties will be obligated to buy the
     Class A Securities specified in such Preemption Notice for the
     consideration per share determined in accordance with Section 7B(b). The
     parties will make representations and warranties customary for similar
     stock purchase transactions, including, in the case of United,
     representations that all filings made by it pursuant to the Exchange Act
     and the Securities Act are complete and accurate in all material respects,
     that the most recent financial statements provided by United to Liberty
     pursuant to Section 2(e) of the New United Covenant Agreement fairly
     present the financial condition and results of operations of United and its
     subsidiaries as of the dates and for the periods covered thereby and that
     United has no material undisclosed liabilities. There shall be no
     conditions to the parties' obligation to close such purchase and sale other
     than (1) the closing of the issuance, grant or sale of the balance of the
     Class A Securities covered by the Issuance Notice, (2) the absence of any
     material breach of any of the representations and warranties described
     above, assuming such representations and warranties had been made both on
     the date of the Issuance Notice and on the closing date of such purchase
     and sale agreement, and (3) in the case of the Liberty Parties' obligation
     to close, (A) the issuance, grant or sale of the balance of the Class A
     Securities specified in the Issuance Notice being on the terms specified
     therein (including, in the case of an underwritten public offering for cash
     of Class A Stock or Rights, the final price of such public offering being
     within the range set forth in the Issuance Notice) and (B) the issuance,
     grant or sale of such Class A Securities occurring within 20 days before or
     after the date specified therefor in the Issuance Notice.

                                       11
<PAGE>

     (d)  Each issuance of Class A Securities to a Liberty Party must be on
     terms not less favorable to such Liberty Party than the most favorable
     terms on which United issues or proposes to issue in the transaction in
     connection with which the preemptive right is being exercised Class A
     Securities to any other Person (without discrimination based on differences
     in the number or amount of Class A Securities to be acquired). Without
     limiting the generality of the immediately preceding sentence, (i) each
     Liberty Party must be given the same options and rights of election, if
     any, as to the kind(s) or amount(s) of consideration to be paid or
     delivered for Class A Securities as any other purchaser is given or was
     proposed to be given in the Issuance Notice and (ii) the purchase price to
     be paid by each Liberty Party upon exercise of its rights under this
     Section 7B will be paid upon terms which are not less favorable than those
     on which the Class A Securities are sold to any other purchaser, unless
     those terms provide for payment in a manner which could not reasonably be
     duplicated by any Liberty Party, such as the transfer of specific property
     to United, in which event such payment will be in cash or such other form
     of consideration as may be reasonably acceptable to United, equal to the
     price per share of the Class A Securities so issued (which if paid other
     than in cash shall be the fair market value of the consideration so paid).
     The giving of an Issuance Notice shall constitute the representation and
     warranty by United to each Liberty Party that (A) the proposed issuance is
     not subject to conditions, contingencies or material terms not disclosed in
     the Issuance Notice or in the accompanying documents delivered therewith;
     and (B) neither the amount or kind of consideration offered by any other
     purchaser of the Class A Securities nor any other terms of the proposed
     issuance or of any other transaction or proposed transaction with such
     purchaser or any of its Affiliates have been established for the purpose of
     circumventing, increasing the cost of exercising or otherwise impairing the
     Liberty Parties' preemptive rights under this Section 7B.

     (e)  Notwithstanding the foregoing, the Liberty Parties will not be
     entitled to acquire Class A Securities pursuant to this Section 7B with
     respect to (i) any issuance or sale of Class A Securities in connection
     with the acquisition of a business (A) from a third party that is not an
     Affiliate of United or of any Founder and (B) that is directly related to
     the then existing businesses conducted by United and its Controlled
     Affiliates, (ii) any issuance or grant of options to purchase shares of
     Class A Stock to employees of United pursuant to an employee benefit plan
     approved by the Board, but only to the extent that the percentage of the
     total outstanding Class A Stock issued and issuable pursuant to all options
     to purchase shares of Common Stock granted pursuant to all such employee
     benefit plans (irrespective of when such options were issued) does not
     exceed 10% of the total outstanding Common Stock of United, (iii) Equity
     Securities issued as a dividend to all holders of Equity Securities or upon
     any subdivision or combination of all shares of Equity Securities, or (iv)
     any issuance of Class A Stock pursuant to the exercise of Rights as to
     which the Liberty Parties shall have been afforded the opportunity to
     exercise their preemptive rights pursuant to this Section 7B.

     (f)  If the Liberty Parties waive or are deemed to have waived the
     preemptive rights granted under this Section 7B with respect to any
     proposed issuance of Class A Securities specified in an Issuance Notice,
     then United shall be free to issue, sell or grant the Class A Securities
     described in such Issuance Notice without the participation of any Liberty
     Party; provided that such issuance, sale or grant closes within 60 days
     after the date of the applicable Issuance Notice and is on terms no more
     favorable to any purchaser than the terms proposed in such Issuance Notice.
     United shall not issue, sell or grant any Class A Securities after any such
     60 day period without again complying with this Section 7B. The provisions
     of this Section 7B shall apply successively to each and every issuance of
     Class A Securities.

SECTION 8.  Representations and Warranties.

Each of the Liberty Parties, severally and not jointly, on the one hand, and
United, on the other, represent and warrant to each other as of the date of this
Agreement as follows:

     (a)  Such party has the right, power, legal capacity and authority to enter
     into and perform its obligations under this Agreement, and this Agreement
     constitutes such party's valid and binding obligation, enforceable in
     accordance with its terms, subject, as to enforceability, to applicable

                                       12
<PAGE>

     bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium
     and similar laws affecting creditors' rights and remedies generally, and to
     general principles of equity, including principles of commercial
     reasonableness, good faith and fair dealing (regardless of whether
     enforcement is sought in a proceeding at law or in equity).

     (b)  Such party has obtained all authorizations, permits, approvals or
     consents of any Persons, including all authorizations, permits, approvals
     or consents of any Governmental Authorities, necessary to enter into and
     perform its obligations under this Agreement, except as would not,
     individually or in the aggregate, adversely affect such party's ability to
     perform its obligations under this Agreement.

     (c)  This Agreement and the transactions it contemplates do not conflict
     with any applicable Law or any agreement to which it is a party or
     constitute a default under any such agreement, except as would not,
     individually or in the aggregate, adversely affect such party's ability to
     perform its obligations under this Agreement.

SECTION 9.  Legend.

     (a)  United shall cause a legend substantially similar to the following
     effect to be placed on each certificate representing any Equity Securities
     or Rights issued to each Liberty Party or its Affiliates:

        "The securities represented by this certificate are subject to a
        Stockholders Agreement and a Standstill Agreement, each dated as of
                       , 2002, copies of which are available from
        UnitedGlobalCom, Inc. upon request, and any sale, pledge, hypothecation,
        transfer, assignment or other disposition of such securities is subject
        to such Stockholders Agreement and Standstill Agreement."

     (b)  Upon surrender to United of any certificate representing any Equity
     Securities or Rights disposed of by a Liberty Party in a transaction
     described in Section 5(a)(ii) or (v), or in clauses (ii), (iii) or (iv) of
     the definition of Transfer in Section 1, United shall promptly cause to be
     issued (i) to the transferee or transferees of such Equity Securities or
     Rights one or more certificates without the legend set forth in Section
     9(a) and (ii) to the holder of Equity Securities or Rights represented by
     such certificates so surrendered one or more certificates representing such
     Equity Securities or Rights, if any, as shall not have been so disposed of,
     with the legend set forth in Section 9(a). Upon termination of this
     Agreement pursuant to Section 11 below and the surrender to United of any
     certificate representing Equity Securities or Rights, United shall cause to
     be issued to the holder of such Equity Securities or Rights one or more
     certificates without the legend set forth in Section 9(a).

SECTION 10.  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 11.  Termination.  The provisions of this Agreement other than Sections
4, 7A and 7B will expire on June 25, 2010, provided that this Agreement will
terminate in its entirety (except as provided in the following sentence) at such
time (whether earlier or later) as the Stockholders Agreement terminates in
accordance with its terms or by the mutual consent of the Controlling Principals
and Liberty. United's obligations under Section 9(b) shall survive the
termination of this Agreement.

SECTION 12.  Notices.  All notices, requests, demands and other communications
required or permitted hereunder shall be in writing, shall be deemed to have
been duly given when delivered personally or, sent by telecopy, or recognized
service providing for guaranteed delivery, addressed as follows:

on the basis of a non-convenient forum. Each party hereby IRREVOCABLY WAIVES ANY

their Permitted Transferees, in the case of the Liberty Parties, and their
permitted successors and assigns any benefits, rights or remedies. Except as
contemplated by the definitions of "Liberty" and "Transfer" neither this

Transferee), by operation of law or otherwise without the prior written consent
of Liberty and United.

SECTION 18.  Severability.  The invalidity or unenforceability of any provision
of this Agreement in any application shall not affect the validity or

this Agreement and not to any particular article, section or other subdivision
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 any statute or regulation are to
it as amended and supplemented from time to time, and to any corresponding

executed this Agreement on a later date. Any reference herein to a "day" or
number of "days" (without the explicit qualification of "Business") shall be
deemed to refer to a calendar day or number of calendar days. If any action or
notice is to be taken or given on or by a particular calendar day, and such

given on the next succeeding Business Day.

                               REGISTRATION RIGHTS

2.1      DEMAND REGISTRATION.

                  (a) Liberty Media or its designee, on behalf of the Liberty
Holders, shall be entitled to make written requests from time to time for Demand
Registration of all or any part of the Registrable Securities held by the
Liberty Holders, provided that each such Demand Registration must be in respect
of Registrable Securities representing not less than the lower of (A) 10% of the
Initial Amount or, with respect to Registrable Securities other than shares of
Class A Stock, a number of such other securities having a fair market value
(based on the average of the closing prices of such securities on the principal
stock exchange or interdealer quotation system on which such securities are
traded for the five consecutive trading days immediately preceding the date of
the written request for such Demand Registration or, if such securities are not
publicly traded, as determined in good faith by the Company's Board of
Directors) equal to at least 10% of the product of (x) the Initial Amount,
multiplied by (y) the average of the closing prices of the Class A Stock on the
principal stock exchange or interdealer quotation system on which the Class A
Stock is traded for the same five trading day period or (B) all of the
Registrable Securities held by the Liberty Holders. Notwithstanding the
foregoing, the Company shall not be obligated to effect more than a total of
five (5) Demand Registrations and Liberty Media and any designee of Liberty
Media may make no more than two requests for a Demand Registration in any
12-month period.

                  (b) Any request for a Demand Registration will specify the
aggregate number and kind of Registrable Securities proposed to be sold and will
also specify the intended method of disposition thereof. A registration will not
count as a Demand Registration until it has become effective and at least 90% of
the Registrable Securities requested to be included in such Demand Registration
have been registered and sold.

                  (c) Upon receipt of any request for a Demand Registration by
Liberty Media or its designee, the Company shall promptly (but in any event
within ten days) give written notice of such proposed Demand Registration to
each of the Liberty Holders that, according to the stock transfer book of the
Company, holds Registrable Securities, and all such Liberty Holders (including
their respective direct or indirect transferees) shall have the right,
exercisable by written notice to the Company within 20 days of their receipt of
the Company's notice, to elect to include in such Demand Registration such
portion of their Registrable Securities as they may request. All such Persons
requesting to have their Registrable Securities included in a Demand
Registration in accordance with the preceding sentence shall be deemed to be
"Requesting Holders" for purposes of this Section 2.1.

                                       3
<PAGE>

                  (d) If Liberty Media or its designee so elects, the offering
of such Registrable Securities pursuant to such Demand Registration shall be in
the form of a "firm commitment" underwritten offering. The Company shall have
the right to select the Underwriters to be used in connection with any offering
under this Section 2.1, provided that such Underwriters, including the managing
Underwriters, shall be reasonably satisfactory to the Requesting Holders that
hold a majority of the Registrable Securities requested to be included in such
Demand Registration. Any request for Demand Registration may specify that
Registrable Securities are to be sold pursuant to a Shelf Registration.

                  (e) The Company will have the right to preempt any Demand
Registration with a primary registration by giving written notice, within ten
Business Days after the request for such Demand Registration was given, of such
intention to Liberty Media indicating that the Company has identified a specific
business need and use for the proceeds of the sale of such securities and had
contemplated such sale of securities prior to the date such written request was
given, and the Company shall use commercially reasonable efforts to effect a
primary registration within 90 days of such notice. In the ensuing primary
registration, the Liberty Holders will have the Piggyback Registration rights
set forth in Section 2.2 hereof. If the Company thereafter decides to abandon
its intention to pursue such sale of securities, it shall give notice thereof to
Liberty Media within two Business Days following the Company's decision. The
Company may exercise the right to preempt a Demand Registration only once in
each 360-day period; provided, that during each 360-day period the Company shall
use its reasonable best efforts to permit a period of at least 180 consecutive
days during which the Liberty Holders may effect a Demand Registration.

                  (f) If a Demand Registration involves an underwritten offering
and the managing Underwriter(s) advise the Company and the Requesting Holders in
writing that, in its opinion, the number of securities requested to be included
in such registration (including securities of the Company that are not
Registrable Securities) exceeds the number that can be sold in such offering
without adversely affecting the price of the offering, the Company will include
in such registration the Registrable Securities requested to be included in such
registration. If the number of Registrable Securities requested to be included
in such registration exceeds the number that, in the opinion of such managing
underwriter, can be sold in such offering, the number of such Registrable
Securities to be included in such Demand Registration shall be allocated pro
rata among all Requesting Holders on the basis of the relative number of
Registrable Securities then held by each such Requesting Holder (provided that
the number of Registrable Securities thereby allocated to any Requesting Holder
for inclusion in such Demand Registration that exceeds such Requesting Holder's
request shall be reallocated among the remaining Requesting Holders in like
manner) or in such other manner as the Requesting Holders may agree. If the
number of Registrable Securities requested to be included in such Demand
Registration is less than the number that, in the opinion of the managing
Underwriter(s), can be sold in such offering without adversely affecting the
price of the offering, the Company may include in such registration the
securities the Company proposes to sell up to the number of securities that, in
the opinion of the managing Underwriter(s), can be so sold in such offering. If
the number of Registrable Securities requested to be included in such Demand
Registration plus the number of securities proposed to be included in such
Demand Registration by the Company is less than the number that, in the opinion
of the managing Underwriter(s), can be sold in such offering without adversely
affecting the price of the offering, the securities requested to be

                                       4
<PAGE>
included in such Demand Registration by other Persons whose requests have been
approved by the Company may be included in such Demand Registration up to the
number of securities that, in the opinion of the managing Underwriter(s), can be
so sold. If any Registrable Securities requested to be registered pursuant to a
Demand Registration under this Section 2.1 are excluded from registration
hereunder, then the Liberty Holder(s) having Registrable Securities excluded
shall have the right to withdraw all, or any part, of their Registrable
Securities from such registration prior to its effectiveness.

2.2      PIGGYBACK REGISTRATION

                  (a) If the Company proposes to file a registration statement
under the Securities Act with respect to an offering of securities for the
account of any Person other than a Liberty Holder or for its own account (other
than a registration statement on Form S-4 or S-8 (or any substitute form that
may be adopted by the Commission)), the Company shall give written notice of
such proposed filing to the Liberty Holders as soon as reasonably practicable
(but in no event less than 15 days before the anticipated filing date),
undertaking to provide each Liberty Holder the opportunity to register on the
same terms and conditions such number of Registrable Securities as such Liberty
Holder may request (a "Piggyback Registration"). Each Liberty Holder will have
five Business Days after any such notice is given to notify the Company as to
whether it wishes to participate in a Piggyback Registration (which notice shall
not be deemed to be a request for a Demand Registration); provided that should a
Liberty Holder fail to provide timely notice to the Company, such Holder will
forfeit any rights to participate in the Piggyback Registration with respect to
such proposed offering. If the registration statement is filed on behalf of a
Person other than the Company, the Company will use its best efforts to have the
amount of Registrable Securities that the Liberty Holders wish to sell included
in the registration statement. If the Company or the Person for whose account
such offering is being made shall determine in its sole discretion not to
register or to delay the proposed offering, the Company may, at its election,
provide written notice of such determination to the Liberty Holders and (i) in
the case of a determination not to effect the proposed offering, shall thereupon
be relieved of the obligation to register such Registrable Securities in
connection therewith, and (ii) in the case of a determination to delay a
proposed offering, shall thereupon be permitted to delay registering such
Registrable Securities for the same period as the delay in respect of the
proposed offering. If the Piggyback Registration involves an underwritten public
offering, any Liberty Holder that requested that Registrable Securities be
included therein may elect, by written notice given to the Company prior to the
effective date of the registration statement therefor, not to register such
Registrable Securities in connection with such Piggyback Registration. As
between the Company and the Selling Holders, the Company shall be entitled to
select the Underwriters in connection with any Piggyback Registration.

                  (b) If a Piggyback Registration involves an underwritten
offering and the managing Underwriter(s) advise the Company in writing that, in
its opinion, the amount of securities requested to be included in such
registration by all selling securityholders and the Company, if applicable,
exceeds the amount which can be sold in such offering without adversely
affecting the price of such offering, then the Company will include in such
Piggyback Registration (A) if such Piggyback Registration relates to a primary
offering initiated by the Company, (i) first, the securities proposed to be sold
by the Company, (ii) second, to the extent the number of securities proposed to
be included in such Piggyback Registration by the

                                       5
<PAGE>

Company is less than the number of securities which the Company has been advised
by the managing Underwriter(s) can be sold in such offering without having the
adverse effect referred to above, the Registrable Securities requested to be
included in such Piggyback Registration by the Liberty Holders (provided that if
the number of such Registrable Securities, in combination with the number of
securities proposed to be included in such Piggyback Registration by the
Company, exceeds the number which the Company has been advised can be sold in
such offering without having the adverse effect referred to above, the number of
such Registrable Securities included in such Piggyback Registration shall be
allocated pro rata among all such Liberty Holders on the basis of the relative
number of Registrable Securities that each of the Liberty Holders has requested
to be included in such Piggy Registration or in such other manner as such
Liberty Holders may agree); and (B) if such Piggyback Registration relates to a
secondary offering initiated by any Person other than a Liberty Holder, (i)
first, the securities requested to be included in such registration by such
other Person (to the extent that the number of such securities does not exceed
the number of securities which the Company has been advised by the managing
Underwriter(s) can be sold in such offering without having the adverse effect
described above), (ii) second, to the extent the number of securities requested
to be included in such registration by such other Person is less than the number
of securities which the Company has been advised by the managing Underwriter(s)
can be sold in such offering without having the adverse effect referred to
above, the Registrable Securities requested to be included in such Piggyback
Registration by the Liberty Holders (provided that if the number of such
Registrable Securities, in combination with the securities of such other Person
to be included in such Piggyback Registration, exceeds the number which the
Company has been advised by the managing Underwriter(s) can be sold in such
offering without having the adverse effect referred to above, the number of such
Registrable Securities of the Liberty Holders included in such Piggyback
Registration shall be allocated pro rata among all such Liberty Holders on the
basis of the relative number of Registrable Securities each such Liberty Holder
has requested to be included in such Piggyback Registration or in such other
manner as such Liberty Holders may agree) and (iii) third, to the extent the sum
of the number of securities requested to be included in such Piggyback
Registration by such other Person plus the number of Registrable Securities
proposed to be included in such Piggyback Registration by the Liberty Holders is
less than the number of securities which the Company has been advised by the
managing Underwriter(s) can be sold in such offering without having the adverse
effect referred to above, the securities proposed to be sold by the Company (to
the extent that the number of such securities does not exceed, in combination
with the securities of such other Person and the Liberty Holders to be included
in such Piggyback Registration, the number of securities which the Company has
been advised by the managing Underwriter(s) can be sold in such offering without
having the adverse effect described above). If as a result of the provisions of
this Section 2.2(b) any Liberty Holder is not entitled to include all
Registrable Securities in a Piggyback Registration that such Liberty Holder has
requested to be so included, such Liberty Holder may withdraw such Liberty
Holder's request to include Registrable Securities in such Piggyback
Registration prior to its effectiveness.

                  (c) The Company shall not grant any piggyback registration or
similar rights to any Person that would provide such Person with piggyback
registration or similar rights that are senior to or pari passu with the rights
granted to the Liberty Holders hereunder.

                                   ARTICLE III

                             REGISTRATION PROCEDURES

3.1      FILINGS; INFORMATION

         In connection with the registration and offering of Registrable
Securities pursuant to Sections 2.1 and 2.2 hereof, the Company will use its
reasonable best efforts to effect the registration and offering of such
Registrable Securities as promptly as is reasonably practicable, and in
connection with any such request:

                  (a) The Company will expeditiously prepare and file with the
Commission a registration statement on any form for which the Company then
qualifies and that counsel for the Company shall deem appropriate and available
for the sale of the Registrable Securities to be registered thereunder in
accordance with the intended method of distribution thereof, and use its
reasonable best efforts to cause such filed registration statement to become and
remain effective for such period, not to exceed 180 days (or two years, in the
case of a Shelf Registration), as may be reasonably necessary to effect the sale
of the Registrable Securities registered thereunder; provided that if the
Company shall furnish to the Selling Holders a certificate signed by the
Company's Chairman, President or any Executive Vice-President or Vice-President
stating that the Company's Board of Directors has determined in good faith that
it would be detrimental or otherwise disadvantageous to the Company or its
stockholders for such a registration statement to be filed as expeditiously as
possible or for Registrable Securities to be offered pursuant to an effective
Shelf Registration, because the disclosure of information in any related
prospectus or prospectus supplement would materially interfere with any
acquisition, financing or other material event or transaction which is then
intended and the public disclosure of which at the time would be materially
prejudicial to the Company, the Company may postpone the filing or effectiveness
of a registration statement or any offering of Registrable Securities pursuant
to an effective Shelf Registration for a period of not more than 90 days;
provided that during each 360-day period the Company shall use its reasonable
best efforts to permit a period of at least 180 consecutive days during which
the Company will effect the registration of Registrable Securities or any
offering of Registrable Securities pursuant to an effective Shelf Registration
in accordance with this Agreement; and provided, further, that if (i) the
effective date of any registration statement filed pursuant to a Demand
Registration would otherwise be at least 45 calendar days, but fewer than 90
calendar days, after the end of the Company's fiscal year, and (ii) the
Securities Act requires the Company to include audited financials as of the end
of such fiscal year, the Company may delay the effectiveness of such
registration statement for such period as is reasonably necessary to include
therein its audited financial statements for such fiscal year.

                  (b) The Company will, if requested, prior to filing such
registration statement or any amendment or supplement thereto, furnish to the
Selling Holders, and each applicable managing Underwriter, if any, copies
thereof, and thereafter furnish to the Selling Holders and each such
Underwriter, if any, such number of copies of such registration statement,
amendment and supplement thereto (in each case including all exhibits thereto
and documents incorporated by reference therein) and the prospectus included in
such registration statement (including each

                                       7
<PAGE>

preliminary prospectus) as the Selling Holders or each such Underwriter may
reasonably request in order to facilitate the sale of the Registrable Securities
by the Selling Holders.

                  (c) After the filing of the registration statement, the
Company will promptly notify the Selling Holders of any stop order issued or, to
the Company's knowledge, threatened to be issued by the Commission and take all
reasonable actions required to prevent the entry of such stop order or to remove
it if entered.

                  (d) The Company will use its commercially reasonable efforts
to qualify the Registrable Securities for offer and sale under such other
securities or blue sky laws of the appropriate jurisdictions in the United
States; keep each such registration or qualification (or exemption therefrom)
effective during the period in which such registration statement is required to
be kept effective; and do any and all other acts and things which may be
reasonably necessary or advisable to enable each Selling Holder to consummate
the disposition of the Registrable Securities owned by such Selling Holder in
such jurisdictions; provided that the Company will not be required to (i)
qualify generally to do business in any jurisdiction where it would not
otherwise be required to qualify but for this paragraph 3.1(d), (ii) subject
itself to taxation in any such jurisdiction or (iii) consent to general service
of process in any such jurisdiction.

                  (e) The Company will as promptly as is practicable notify the
Selling Holders, at any time when a prospectus relating to the sale of the
Registrable Securities is required by law to be delivered in connection with
sales by an Underwriter or dealer, of the occurrence of any event requiring the
preparation of a supplement or amendment to such prospectus so that, as
thereafter delivered to the purchasers of such Registrable Securities, such
prospectus will not contain an untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading and promptly make available to the Selling Holders and to
the Underwriters any such supplement or amendment. Upon receipt of any notice of
the occurrence of any event of the kind described in the preceding sentence,
Selling Holders will forthwith discontinue the offer and sale of Registrable
Securities pursuant to the registration statement covering such Registrable
Securities until receipt by the Selling Holders and the Underwriters of the
copies of such supplemented or amended prospectus and, if so directed by the
Company, the Selling Holders will deliver to the Company all copies, other than
permanent file copies then in the possession of Selling Holders, of the most
recent prospectus covering such Registrable Securities at the time of receipt of
such notice. If the Company shall give such notice, the Company shall extend the
period during which such registration statement shall be maintained effective as
provided in Section 3.1(a) hereof by the number of days during the period from
and including the date of the giving of such notice to the date when the Company
shall make available to the Selling Holders such supplemented or amended
prospectus.

                  (f) The Company will enter into customary agreements
(including an underwriting agreement in customary form) and take such other
actions (including, without limitation, participation in road shows and investor
conference calls) as are required in order to expedite or facilitate the sale of
such Registrable Securities.

                  (g) At the request of any Underwriter in connection with an
underwritten offering the Company will furnish (i) an opinion of counsel,
addressed to the Underwriters,

                                       8
<PAGE>

covering such customary matters as the managing Underwriter may reasonably
request and (ii) a comfort letter or comfort letters from the Company's
independent public accountants covering such customary matters as the managing
Underwriter may reasonably request.

                  (h) If requested by the managing Underwriter or any Selling
Holder, the Company shall promptly incorporate in a prospectus supplement or
post-effective amendment such information concerning the Underwriters or Selling
Holders as the managing Underwriter or any Selling Holder reasonably requests to
be included therein, including without limitation, with respect to the
Registrable Securities being sold by such Selling Holder, the purchase price
being paid therefor by the Underwriters and with respect to any other terms of
the underwritten offering of the Registrable Securities to be sold in such
offering, and promptly make all required filings of such prospectus supplement
or post effective amendment.

                  (i) The Company shall promptly make available for inspection
by any Selling Holder or Underwriter participating in any disposition pursuant
to any registration statement, and any attorney, accountant or other agent or
representative retained by any such Selling Holder or Underwriter (collectively,
the "Inspectors"), all financial and other records, pertinent corporate
documents and properties of the Company (collectively, the "Records"), as shall
be reasonably necessary to enable them to exercise their due diligence
responsibility, and cause the Company's officers, directors and employees to
supply all information requested by any such Inspector in connection with such
registration statement; provided, however, that unless the disclosure of such
Records is necessary to avoid or correct a misstatement or omission in the
registration statement or the release of such Records is ordered pursuant to a
subpoena or other order from a court of competent jurisdiction, the Company
shall not be required to provide any information under this subparagraph (i) if
(A) the Company believes, after consultation with counsel for the Company, that
to do so would cause the Company to forfeit an attorney-client privilege that
was applicable to such information or (B) if either (1) the Company has
requested and been granted from the Commission confidential treatment of such
information contained in any filing with the Commission or documents provided
supplementally or otherwise or (2) the Company reasonably determines in good
faith that such Records are confidential and so notifies the Inspectors in
writing, unless prior to furnishing any such information with respect to (A) or
(B) such Holder of Registrable Securities requesting such information agrees to
enter into a confidentiality agreement in customary form and subject to
customary exceptions; provided further, however, that each Holder of Registrable
Securities agrees that it will, upon learning that disclosure of such Records is
sought in a court of competent jurisdiction, give notice to the Company and
allow the Company, at its expense, to undertake appropriate action to prevent
disclosure of the Records deemed confidential.

                  (j) The Company shall cause the Registrable Securities
included in any registration statement to be (i) listed on each securities
exchange, if any, on which similar securities issued by the Company are then
listed, or (ii) authorized to be quoted and/or listed (to the extent applicable)
on the Nasdaq National Market if the Registrable Securities so qualify.

                  (k) The Company shall provide a CUSIP number (if one has not
already been provided) for the Registrable Securities included in any
registration statement not later than the effective date of such registration
statement.

                  (l) The Company shall cooperate with each Selling Holder and
each Underwriter participating in the disposition of such Registrable Securities
and their respective counsel in connection with any filings required to be made
with the National Association of Securities Dealers, Inc.

                  (m) The Company shall during the period when the prospectus is
required to be delivered under the Securities Act, promptly file all documents
required to be filed with the Commission pursuant to Sections 13(a), 13(c), 14
or 15(d) of the Exchange Act.

                  (n) The Company will make generally available to its security
holders, as soon as reasonably practicable, an earnings statement covering a
period of 12 months, beginning within three months after the effective date of
the registration statement, which earnings statement shall satisfy the
provisions of Section 11(a) of the Securities Act and the rules and regulations
of the Commission thereunder.

         The Company may require Selling Holders promptly to furnish in writing
to the Company such information regarding such Selling Holders, the plan of
distribution of the Registrable Securities and other information as the Company
may from time to time reasonably request or as may be legally required in
connection with such registration.

3.2      REGISTRATION EXPENSES

         In connection with any registration effected hereunder, the Company

Inc., (ii) fees and expenses of compliance with securities or blue sky laws

                                   ARTICLE IV

                        INDEMNIFICATION AND CONTRIBUTION

4.1      INDEMNIFICATION BY THE COMPANY

         The Company agrees to indemnify and hold harmless each Selling Holder
and its Affiliates and their respective officers, directors, partners,
stockholders, members, employees, agents and representatives and each Person (if
any) that controls a Selling Holder within the meaning of either Section 15 of
the Securities Act or Section 20 of the Exchange Act, from and

                                       10
<PAGE>

against any and all losses, claims, damages, liabilities, costs and expenses
(including reasonable attorneys' fees) caused by, arising out of, resulting from
or related to any untrue statement or alleged untrue statement of a material
fact contained or incorporated by reference in any registration statement or
prospectus relating to the Registrable Securities (as amended or supplemented if
the Company shall have furnished any amendments or supplements thereto) or any
preliminary prospectus, or caused by any omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, except insofar as such losses, claims,
damages or liabilities are caused by or based upon any information furnished in
writing to the Company by or on behalf of such Selling Holder expressly for use
therein or by the Selling Holder's failure to deliver a copy of the final
prospectus after the Company has furnished the Selling Holder with copies of the
same and such final prospectus corrected errors or omissions in a preliminary
prospectus that are the basis of such losses, claims, damages or liabilities.
Such indemnity shall remain in full force and effect regardless of any
investigation made by or on behalf of any Selling Holder or its Affiliates and
shall survive the transfer of the Registrable Securities by such Selling Holder.

4.2      INDEMNIFICATION BY SELLING HOLDERS

         Each Selling Holder agrees to indemnify and hold harmless the Company,
its officers and directors, and each Person, if any, that controls the Company
within the meaning of either Section 15 of the Securities Act or Section 20 of
the Exchange Act to the same extent as the foregoing indemnity from the Company
to each Selling Holder, but only with reference to information furnished in
writing by or on behalf of such Selling Holder expressly for use in any
registration statement or prospectus relating to the Registrable Securities, or
any amendment or supplement thereto, or any preliminary prospectus. Each such
Selling Holder's liability under this Section 4.2 shall be limited to an amount
equal to the net proceeds (after deducting the underwriting discount and
expenses) received by such Selling Holder from the sale of such Registrable
Securities by such Selling Holder. The obligation of each Selling Holder shall
be several and not joint.

4.3      CONDUCT OF INDEMNIFICATION PROCEEDINGS

         In case any proceeding (including any governmental investigation) shall
be instituted involving any Person in respect of which indemnity may be sought
pursuant to Section 4.1 or Section 4.2, such Person (the "Indemnified Party")
shall promptly so notify the Person against whom such indemnity may be sought
(the "Indemnifying Party") in writing; provided that the failure of the
Indemnified Party to give notice as provided herein shall not relieve the
Indemnifying Party of its obligations under this Article IV with respect to such
proceeding except to the extent that the Indemnifying Party is actually and
materially prejudiced by such failure to give notice. The Indemnifying Party
shall be entitled to participate in such proceeding and, subject to the
following sentence, assume the defense thereof with counsel retained by the
Indemnifying Party (the fees and expenses of which counsel shall be paid by the
Indemnifying Party) provided that such counsel is reasonably satisfactory to the
Indemnified Party. In any such proceeding, any Indemnified Party shall have the
right to retain its own counsel, but, after notice from the Indemnifying Party
of its election to assume the defense of such proceeding and of its retention of
counsel reasonably satisfactory to the Indemnified Party whose representation of
the Indemnified Party would not present such counsel with a conflict of
interest, the

                                       11
<PAGE>

Indemnifying Party shall not be liable for the fees and expenses of separate
counsel retained by the Indemnified Party subsequently incurred in connection
with the defense of such proceeding (other than reasonable costs of
investigation), unless (i) the Indemnifying Party and the Indemnified Party
shall have mutually agreed to the retention of such separate counsel or (ii) the
named parties to or targets of any such proceeding (including any impleaded
parties) include both the Indemnified Party and the Indemnifying Party and the
Indemnified Party shall have reasonably concluded that there may be legal
defenses available to it which are different from or additional to those
available to the Indemnifying Party (in which case the Indemnifying Party shall
not be entitled to assume the defense of such proceeding on the Indemnified
Party's behalf). It is understood that the Indemnifying Party shall not, in
connection with any proceeding or related proceedings in the same jurisdiction,
be liable for the fees and expenses of more than one separate firm of attorneys
(in addition to any local counsel) at any time for all such Indemnified Parties,
and that all such fees and expenses shall be reimbursed as they are incurred. In
the case of any such separate firm for the Indemnified Parties, such firm shall
be designated in writing by the Indemnified Parties. The Indemnifying Party
shall not be liable for any settlement of any proceeding effected without its
written consent, but if settled with such consent (not to be unreasonably
withheld), or if there be a final judgment for the plaintiff, the Indemnifying
Party shall indemnify and hold harmless such Indemnified Parties from and
against any loss or liability (to the extent stated above) by reason of such
settlement or judgment. No Indemnifying Party will consent to entry of any
judgment or enter into any settlement which does not include as an unconditional
term thereof the giving by the claimant or plaintiff to the Indemnified Party of
a release from all liability in respect of such claim or proceeding.

4.4      CONTRIBUTION

         If the indemnification provided for in this Article IV is unavailable
to an Indemnified Party in respect of any losses, claims, damages or liabilities
in respect of which indemnity is to be provided hereunder, then each such
Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall to the
fullest extent permitted by law contribute to the amount paid or payable by such
Indemnified Party as a result of such losses, claims, damages or liabilities in
such proportion as is appropriate to reflect the relative fault of such party in
connection with the statements or omissions that resulted in such losses,
claims, damages or liabilities, as well as any other relevant equitable
considerations. The relative fault of the Company and a Selling Holder shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by such party and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.

         The Company and each Selling Holder agree that it would not be just and
equitable if contribution pursuant to this Section 4.4 were determined by pro
rata allocation or by any other method of allocation that does not take account
of the equitable considerations referred to in the immediately preceding
paragraph. The amount paid or payable by an Indemnified Party as a result of the
losses, claims, damages or liabilities referred to in the immediately preceding
paragraph shall be deemed to include, subject to the limitations set forth
above, any legal or other expenses reasonably incurred by such Indemnified Party
in connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Article IV, no Selling Holder shall be
required to contribute any amount in excess of the amount by which the

                                       12
<PAGE>

net proceeds of the offering (after deducting the underwriting discount and
expenses) received by such Selling Holder exceeds the amount of any damages
which such Selling Holder has otherwise been required to pay by reason of such
untrue or alleged untrue statement or omission or alleged omission. No person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to contribution from any Person who was
not guilty of such fraudulent misrepresentation.

                                    ARTICLE V

                                  MISCELLANEOUS

5.1      PARTICIPATION IN UNDERWRITTEN REGISTRATIONS

         No Person may participate in any underwritten registered offering
contemplated hereunder unless such Person (a) agrees to sell its securities on
the basis provided in any underwriting arrangements approved by the Persons
entitled hereunder to approve such arrangements, (b) completes and executes all
questionnaires, powers of attorney, custody arrangements, indemnities,
underwriting agreements and other documents reasonably required under the terms
of such underwriting arrangements and this Agreement and (c) furnishes in
writing to the Company such information regarding such Person, the plan of
distribution of the Registrable Securities and other information as the Company
may from time to time request or as may be legally required in connection with
such registration; provided, however, that no such Person shall be required to
make any representations or warranties in connection with any such registration
other than representations and warranties as to (i) such Person's ownership of
his or its Registrable Securities to be sold or transferred free and clear of
all liens, claims and encumbrances, (ii) such Person's power and authority to
effect such transfer and (iii) such matters pertaining to compliance with
securities laws as may be reasonably requested; provided further, however, that
the obligation of such Person to indemnify pursuant to any such underwriting
agreements shall be several, not joint and several, among such Persons selling
Registrable Securities, and the liability of each such Person will be in
proportion to, and provided further that such liability will be limited to, the
net amount received by such Person from the sale of such Person's Registrable
Securities pursuant to such registration.

5.2      RULE 144

         The Company covenants that it will file any reports required to be
filed by it under the Securities Act and the Exchange Act and that it will take
such further action as the Liberty Holders may reasonably request to the extent
required from time to time to enable the Liberty Holders to sell Registrable
Securities without registration under the Securities Act within the limitation
of the exemptions provided by Rule 144 under the Securities Act, as such Rule
may be amended from time to time, or any similar rule or regulation hereafter
adopted by the Commission. Upon the request of any Liberty Holder, the Company
will deliver to such Liberty Holder a written statement as to whether it has
complied with such reporting requirements.

<PAGE>

5.3      HOLDBACK AGREEMENTS

         For so long as the Liberty Holders own 10% or more of any class of
capital stock of the Company, subject to their rights pursuant to Sections 2.1
and 2.2 hereof, each Liberty Holder and the Company agrees that if requested by
the managing Underwriters in an underwritten public offering of equity
securities of the Company (including debt securities convertible or exchangeable
for such equity securities), whether for the account of the Company or another
Person, it will not effect any public offer to sell, sale or distribution,
including pursuant to Rule 144 under the Securities Act, of any equity security
of the Company (or any such convertible or exchangeable debt security), in each
case other than as part of such underwritten public offering and subject to
other customary exceptions, during the seven days prior to, and during the
180-day period (or such lesser period as the managing Underwriters may require)
beginning on the effective date of the registration statement for such
underwritten offering (or, in the case of an offering pursuant to a Shelf
Registration, the pricing date for such underwritten offering), provided that in
connection with such underwritten offering each officer and director of the
Company and each Founder is subject to restrictions identical to those imposed
on the Liberty Holders.

5.4      TERMINATION

         The registration rights granted under this Agreement will terminate at
such time as there shall no longer be any Registrable Securities.

5.5      AMENDMENTS, WAIVERS, ETC.

         This Agreement may not be amended, waived or otherwise modified or
terminated except by an instrument in writing signed by the Company and the
holders of at least 50% of the Registrable Securities then held by all the
Liberty Holders.

5.6      COUNTERPARTS

         This Agreement may be executed in one or more counterparts, all of
which shall be considered one and the same agreement. Each party need not sign
the same counterpart.

5.7      ENTIRE AGREEMENT

         This Agreement constitutes the entire agreement and supersedes all
prior agreements and understandings, both written and oral, among the parties
with respect to the subject matter hereof.

5.8      GOVERNING LAW

         This Agreement shall be governed by, and construed in accordance with,
the internal laws of the State of Colorado regardless of the laws that might
otherwise govern under applicable principles of conflicts of law thereof.

5.9      ASSIGNMENT OF REGISTRATION RIGHTS

         Each Liberty Holder may assign all or any part of its rights under this
Agreement to any Person to whom such Liberty Holder sells, transfers, assigns or
pledges Registrable Securities. If a Liberty Holder shall assign its rights
pursuant to this Agreement in connection with the transfer of less than all its
Registrable Securities, such Liberty Holder shall also retain its rights with
respect to its remaining Registrable Securities.

5.10     NOTICES

         All notices, demands, requests, consents, approvals or other
communications (collectively, "Notices") required or permitted to be given

                               EXCHANGE AGREEMENT

         This Exchange Agreement (this "Agreement") dated as of _________ __,
2002, is entered into among New UnitedGlobalCom, Inc., a Delaware corporation
that upon the effectiveness of the Merger described under "Background" below
will be renamed UnitedGlobalCom, Inc. ("United"), and each of the individuals
indicated as a "Stockholder" on the signature pages hereto (the "Stockholders").

                                   Background

         As contemplated by the Amended and Restated Agreement and Plan of
Restructuring and Merger, dated as of December 31, 2001 (the "Merger
Agreement"), among UnitedGlobalCom, Inc., a Delaware corporation that upon the
effectiveness of the Merger will be renamed UGC Holdings, Inc. ("Old United"),
United, United/New United Merger Sub, Inc., a Delaware corporation ("Merger
Sub"), Liberty Media Corporation, a Delaware corporation, Liberty Media
International, Inc., a Delaware corporation, Liberty Global, Inc., a Delaware
corporation, and the Persons indicated as "Founders" on the signature pages
thereto, the Stockholders have purchased and are the record and beneficial
holders of an aggregate of 1,500 shares of the Series E Preferred Stock, par
value $0.01 per share, of Old United (the "Preferred Shares"). In the merger
(the "Merger") of Merger Sub with and into Old United contemplated by the Merger
Agreement, the Preferred Shares will be converted into an aggregate of 1,500
shares of the Class A Common Stock, par value $0.01 per share ("Surviving Entity
Class A Stock"), of Old United as the surviving entity in the Merger (the
"Surviving Entity"). Pursuant to the terms of the Surviving Entity's Restated
Certificate of Incorporation (the "Surviving Entity Charter"), (a) immediately
upon any transfer of a share of Surviving Entity Class A Stock to any Person
other than a Permitted Transferee who is also a Principal or a Related Party,
such share of Surviving Entity Class A Stock shall automatically convert into
one share of the Class C Common Stock, par value $0.01 per share ("Surviving
Entity Class C Stock"), of the Surviving Entity and (b) immediately upon the
occurrence of a Class B Event, each outstanding share of Surviving Entity Class
A Stock shall automatically convert into one share of Surviving Entity Class C
Stock. The parties hereto desire to set forth the terms upon which the
Stockholders may exchange shares of Surviving Entity Class C Stock with United
for shares of Class A Stock, par value $0.01 per share ("United Class A Stock"),
of United. It is a condition to the consummation of the transactions
contemplated by the Merger Agreement, including the Merger, that United and the
Stockholders each execute and deliver this Agreement.

                                    Agreement

         In consideration of the foregoing premises and for other good and

number of newly issued shares of United Class A Stock equal to the product of
(a) the number of shares of Surviving Entity Class C Stock surrendered for
exchange in accordance with this Agreement and (b) the Exchange Rate in effect

other than a Permitted Transferee who is also a Principal or a Related Party.
Notwithstanding anything in the foregoing to the contrary, no Stockholder shall
be entitled to cause United to exchange any shares of Surviving Entity Class C

delivered a Promissory Note pursuant to a Subscription Agreement in payment of
the Purchase Price of any shares of Old United Series E Preferred Stock, unless
such Stockholder's liability under any such Promissory Note has been satisfied
in full. If the Stockholder's liability under a Promissory Note is satisfied by
means of any transaction or arrangement involving such Stockholder or any
Affiliate of such Stockholder becoming indebted to United, such indebtedness (or
any substitute or successor arrangement) shall provide for full recourse to the
Stockholder or the relevant Affiliate in the event of the nonpayment thereof,
shall provide for the payment of interest at a fair market rate and contain
other terms and conditions consistent with an arm's length, fair market
transaction, all of which terms shall be reasonably acceptable to

Liberty. The Stockholder or the relevant Affiliate shall maintain at all times
from the incurrence of such indebtedness until such time that such indebtedness
is satisfied in full, unencumbered assets in an amount sufficient for the
repayment of such indebtedness.

         Section 3. No Fractional Shares. No fractional shares of United Class A
Stock shall be issued upon the exchange of shares of Surviving Entity Class C
Stock. If more than one share of Surviving Entity Class C Stock is surrendered
for exchange by the same holder at the same time, the number of full shares of
United Class A Stock that shall be issuable upon exchange thereof shall be
computed on the basis of the aggregate number of shares of Surviving Entity
Class C Stock so surrendered for exchange. Any fractional shares of United Class
A Stock shall instead be rounded down to the nearest whole share if such
fraction is less than 0.5 and rounded up to the nearest whole share if such
fraction is equal to or greater than 0.5 and United shall issue in such exchange
the appropriate number of full shares of United Class A Stock.

         Section 4. Procedure for Exchange. A Stockholder desiring to exchange
any shares of Surviving Entity Class C Stock pursuant to this Agreement shall
surrender the certificate or certificates representing the shares of Surviving
Entity Class C Stock to be exchanged, duly endorsed and accompanied by
instruments of transfer to the Secretary of United. Upon receipt by the
Secretary of the foregoing certificate or certificates and instruments of
transfer, United shall cause to be issued to the Stockholder who surrendered
such certificate or certificates, or such Stockholder's nominee or nominees, the
appropriate number of shares of United Class A Stock and shall issue and deliver
to such Stockholder, or such Stockholder's nominee or nominees, a certificate or
certificates representing such shares. Any such exchange shall be deemed to have
been effected at the close of business on the date such shares are surrendered
for exchange in accordance with this Agreement, and the Person or Persons
entitled to receive the shares of United Class A Stock issuable upon such
exchange shall be treated for all purposes as the record holder or holders of
such shares of United Class A Stock on that date. A number of shares of United
Class A Stock equal to the sum of (a) the number of shares issuable upon
exchange of shares of Surviving Entity Class C Stock held by Stockholders from
time to time plus (b) the number of shares issuable upon exchange of shares of
Surviving Entity Class C Stock issuable upon conversion of shares of Surviving
Entity Class A Stock outstanding from time to time shall be set aside and
reserved for issuance upon such exchange.

conditions agreed upon by the parties hereto, and no other agreements, oral or
otherwise, regarding the subject matter hereof shall have any effect unless in
writing and executed by the parties after the date of this Agreement.

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, and only a State or Federal
