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

1,500,000 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.

number of shares of Surviving Entity Class C Stock surrendered for exchange in

------------
(1) The initial Exchange Rate will be equal to 1/1,500,000th of the result
    (rounded to the nearest 1/10,000th of a share) of (A) the quotient of X
    divided by Y minus (B) X. For purposes of the foregoing, "X" shall be equal

any shares of Surviving Entity Class A Stock or Surviving Entity Class C Stock
to any Person 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 Stock held by such Stockholder pursuant to this
Agreement if such Stockholder 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.

SECTION 5.  Entire Agreement.  This Agreement contains all the terms and
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.

SECTION 6.  Applicable Law, Jurisdiction.  This Agreement shall be governed by
Colorado law without regard to conflicts of law rules. The parties hereby
irrevocably submit to the exclusive jurisdiction of any Colorado State or United
States Federal court sitting in Colorado, and only a State or Federal court
sitting in Colorado will have any jurisdiction 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

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 8.  Headings.  The headings in this Agreement are for convenience only
and are not to be considered in interpreting this Agreement.

SECTION 9.  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.

implied, is intended to confer upon any Person other than the parties hereto and
their permitted successors and assigns any benefits, rights or remedies;
provided that, Liberty is an intended beneficiary of the provisions set forth in
the antepenultimate, penultimate and final sentences of Section 2, and each of
the parties hereto acknowledges and agrees that Liberty would be irreparably
harmed by any breach of such provisions, and could not be made whole by monetary
damages. Accordingly, Liberty, in addition to any other remedy to which it may
be entitled at law or in equity as an intended beneficiary of such provisions,
shall be entitled to compel specific performance of such provisions. Neither
this Agreement nor the rights or obligations of any party may be assigned or
delegated by operation of law or otherwise without the prior written consent of
each of the parties hereto; provided that, any Person that is a Permitted
Transferee who is also a Principal or a Related Party and who is the transferee
of any shares of Surviving Entity Class A Stock or Surviving Entity Class C
Stock shall, in connection with such transfer, execute a counterpart of this
Agreement and thereupon become a party to and subject to the terms of this
Agreement as a "Stockholder."

SECTION 11.  Severability.  The invalidity or unenforceability of any provision
of this Agreement in any application shall not affect the validity or

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

may have executed this Agreement on a later date.

SECTION 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.

SECTION 14.  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 of the parties hereto.

                             1993 STOCK OPTION PLAN

                (AS AMENDED AND RESTATED EFFECTIVE JUNE 1, 2001)

                                    ARTICLE I

                                  INTRODUCTION

         1.1 ESTABLISHMENT. United International Holdings, Inc., a Delaware
corporation ("UIH"), effective June 1, 1993, established the United
International Holdings, Inc. 1993 Stock Option Plan (the "Plan") for certain
employees of the Company (as defined in subsection 2.1(e)) and certain
consultants to the Company. UIH changed its name to UnitedGlobalCom, Inc.
effective as of July 23, 1999. The name of the Plan has been changed
accordingly, effective as of August 27, 1999, to UnitedGlobalCom, Inc. 1993
Stock Option Plan.

         1.2 PURPOSES. The purposes of the Plan are to provide those who are
selected for participation in the Plan with added incentives to continue in the
long-term service of the Company and to create in such persons a more direct
interest in the future success of the operations of the Company by relating
incentive compensation to increases in shareholder value, so that the income of
those participating in the Plan is more closely aligned with the income of the
Company's shareholders. The Plan is also designed to provide a financial
incentive that will help the Company attract, retain and motivate the most
qualified employees and consultants.

         1.3 EFFECTIVE DATE; AMENDMENT. The initial effective date of the Plan
was June 1, 1993. The Plan is amended and restated, as of March 24, 2000, to
incorporate all amendments since the initial effective date. The provisions of
the Plan, as so amended and restated, shall apply to any Option (as defined in
subsection 2.1(l)) granted on or after March 24, 2000, and, to the extent that
the provisions of this amended and restated Plan do not adversely affect the
Option, shall also apply to Options granted prior to March 24, 2000.

                                   ARTICLE II

                                   DEFINITIONS

however, that for purposes of Incentive Options granted pursuant to the Plan, an
"Affiliated Corporation" means any parent or subsidiary of UnitedGlobalCom as
defined in Section 424 of the Code.

                                   ARTICLE III

                               PLAN ADMINISTRATION

         3.1 GENERAL . The Committee shall be responsible for administration of
the Plan. The Committee shall consist of members of the Board who are empowered
hereunder to take actions in administration of the Plan. Members of the
Committee shall be appointed from time to time by the Board, shall serve at the
pleasure of the Board and may resign at any time upon written notice to the
Board. The Committee shall be so constituted that it satisfies the requirement
of "disinterested administration" imposed by Rule 16b-3 promulgated by the
Securities and Exchange Commission under the Securities Exchange Act of 1934, as
such rule may be amended from time to time, and each successor applicable rule
thereunder. The Committee shall determine the form or forms of the Option
Certificates and other agreements with Option Holders that shall evidence the
particular provisions, terms, conditions, rights and duties of UnitedGlobalCom
and the Option Holders with respect to Options granted pursuant to the Plan,
which provisions need not be identical except as may be provided herein;
provided, however, that Eligible Consultants shall not be eligible to receive
Incentive Options. The Committee may from time to time adopt such rules and
regulations for carrying out the purposes of the Plan as it may deem proper and
in the best interests of the Company. The Committee may correct any defect,
supply any omission or reconcile any inconsistency in the Plan or in any
agreement entered into hereunder in the

                                        3
<PAGE>
manner and to the extent it shall deem expedient and it shall be the sole and
final judge of such expediency. No member of the Committee shall be liable for
any action or determination made in good faith. The determinations,
interpretations and other actions of the Committee pursuant to the provisions of
the Plan shall be binding and conclusive for all purposes and on all persons.

                                   ARTICLE IV

                            STOCK SUBJECT TO THE PLAN

         4.1 NUMBER OF SHARES. The total number of Shares as to which Options
may be granted pursuant to the Plan shall be 9,200,000 in the aggregate. Such
number shall be adjusted in accordance with the provisions of Section 4.2.
Shares issued upon the exercise of Options shall be applied to reduce the
maximum number of Shares remaining available for use under the Plan. Shares
underlying expired or terminated and unexercised Options are available for grant
of Options under the Plan. Shares withheld by the Company pursuant to Section
10.2 and Shares used to pay the Option Price are not available for the grant of
Options under the Plan. The Company shall at all times during the term of the
Plan and while any Options are outstanding retain as authorized and unissued
Stock, or as treasury Stock, at least the number of Shares from time to time
required under the provisions of the Plan, or otherwise assure itself of its
ability to perform its obligations hereunder.

         4.2 ADJUSTMENTS FOR STOCK SPLIT, STOCK DIVIDEND, ETC. If
UnitedGlobalCom shall at any time increase or decrease the number of its
outstanding Shares by means of payment of a stock dividend or any other
distribution upon such Shares payable in Stock, or through a stock split,
subdivision, consolidation, combination, reclassification or recapitalization
involving the Stock, or change in any way the rights and privileges of such
Shares, then the numbers, rights and privileges of the following shall be
increased, decreased or changed in like manner as if the corresponding Shares
had been issued and outstanding, fully paid and nonassessable at the time of
such occurrence: (a) the Shares as to which Options may be granted under the
Plan; and (b) the Shares then subject to each outstanding Option. Upon any
occurrence described in this Section 4.2, the total Option Price under each then
outstanding Option shall remain unchanged but shall be apportioned ratably over
the increased or decreased number of Shares subject to the Option.

         4.3 ADJUSTMENTS FOR CERTAIN DISTRIBUTIONS OF PROPERTY. If
UnitedGlobalCom shall at any time distribute with respect to its Stock assets or
securities of other persons (excluding cash dividends or distributions payable
out of capital surplus and dividends or other distributions referred to in
Section 4.2 or 4.4), then the Option Price of outstanding Options shall be
adjusted to reflect the fair market value of the assets or securities
distributed, UnitedGlobalCom shall provide for the delivery upon exercise of
such Options of cash in an amount equal to the fair market value of the assets
or securities distributed or a combination of such actions shall be taken, all
as determined by the Committee in its discretion. Fair market value of the
assets or securities distributed for this purpose shall be as determined by the
Committee.

         4.4 DISTRIBUTIONS OF CAPITAL STOCK AND INDEBTEDNESS. If
UnitedGlobalCom shall at any time distribute with respect to its Stock shares of
its capital stock (other than Stock) or evidences of indebtedness, then a
proportionate part of such capital stock and evidences of indebtedness shall be
set aside for each outstanding Option and, upon the exercise of such Option,
delivered to the Option Holder.

                                        4
<PAGE>

         4.5 NO RIGHTS AS STOCKHOLDER. An Option Holder shall have none of the
rights of a stockholder with respect to the Shares subject to an Option until
such Shares are transferred to the Option Holder upon the exercise of such
Option. Except as provided in this Article IV, no adjustment shall be made for
dividends, rights or other property distributed to stockholders (whether
ordinary or extraordinary) for which the record date is prior to the date such
Shares are so transferred.

         4.6 FRACTIONAL SHARES. No adjustment or substitution provided for in
this Article IV shall require UnitedGlobalCom to issue a fractional share. The
total substitution or adjustment with respect to each Option shall be limited by
deleting any fractional share.

         4.7 DETERMINATION BY THE COMMITTEE, ETC. Adjustments under this Article
IV shall be made by the Committee, whose determinations with regard thereto
shall be final and binding.

                                    ARTICLE V

                                  PARTICIPATION

         5.1 IN GENERAL. In accordance with the provisions of the Plan, the
Committee shall, in its sole discretion, select Option Holders from among
Eligible Employees and Eligible Consultants to whom Options will be granted and
shall specify the number of Shares subject to each Option and such other terms
and conditions of each Option as the Committee may deem necessary or desirable
and consistent with the terms of the Plan. Eligible Employees shall be selected
from the employees of the Company who are performing services in the management,
operation and growth of the Company, and contribute, or are expected to
contribute, to the achievement of long-term corporate objectives. Eligible
Consultants shall be selected from the consultants and other individuals who
provide services to the Company with respect to the operation and growth of the
Company and who contribute, or are expected to contribute, to the achievement of
long-term corporate objectives. Eligible Employees and Eligible Consultants may
be granted from time-to-time one or more Options. The grant of each such Option
shall be separately approved by the Committee, and receipt of one such Option
shall not result in automatic receipt of any other Option. Upon determination by
the Committee that an Option is to be granted to an Eligible Employee or
Eligible Consultant, written notice shall be given to such person, specifying
the terms, conditions, rights and duties related thereto.

         5.2 MAXIMUM SHARE GRANT. The maximum number of Shares that may be
subject to all Options granted to an Option Holder in a calendar year is 500,000
Shares.

                                   ARTICLE VI

                                  STOCK OPTIONS

         6.1 GRANT OF OPTIONS TO ELIGIBLE EMPLOYEES AND ELIGIBLE CONSULTANTS.
Coincident with or following designation for participation in the Plan, Eligible
Employees and Eligible Consultants may be granted one or more Options. The
Committee in its sole discretion shall designate whether an Option is an
Incentive Option or a Non-Qualified Option. Incentive Stock Options may be
granted only to Eligible

                                        5

<PAGE>

Employees. The Committee may grant both an Incentive Option and a Non-Qualified
Option to an Eligible Employee at the same time or at different times. Incentive
Options and Non-Qualified Options, whether granted at the same time or at
different times, shall be deemed to have been awarded in separate grants and
shall be clearly identified, and in no event shall the exercise of one Option
affect the right to exercise any other Option or affect the number of shares for
which any other Option may be exercised. An Option shall be considered as having
been granted on the date specified in the grant resolution of the Committee.

         6.2 OPTION CERTIFICATES. Each Option granted under the Plan shall be
evidenced by a written stock option certificate or agreement (an "Option
Certificate") issued by UnitedGlobalCom in the name of the Option Holder and in
such form as may be approved by the Committee. The Option Certificate shall
incorporate and conform to the terms and conditions set forth herein as well as
such other terms and conditions that are not inconsistent as the Committee may
consider appropriate in each case.

         6.3 CERTAIN OPTION TERMS. Options granted pursuant to the Plan shall
have terms and conditions consistent with the following in addition to the terms
and conditions set forth elsewhere herein:

                  (a) NUMBER OF SHARES. Each Option Certificate shall state that
it covers a specified number of shares of Stock, as determined by the Committee.

                  (b) PRICE. Each Option shall have an Option Price that is
determined by the Committee. Incentive Stock Options shall have an Option Price
that is equal to or greater than the Fair Market Value of the Stock on the date
the Option is granted.

                  (c) DURATION OF AND EXERCISE OF OPTIONS. Each Option
Certificate shall state the period of time, determined by the Committee, within
which the Option may be exercised by the Option Holder (the "Option Period").
The Option Period must end, in all cases, not more than ten years from the date
the Option is granted. Each Option shall become exercisable (vest) over such
period of time, as determined by the Committee.

                  (d) TERMINATION OF EMPLOYMENT OR SERVICE, DEATH, DISABILITY,
ETC. The Committee may specify the period after which an Option may be exercised
following termination of the employment of an Eligible Employee or termination
of relationship with an Eligible Consultant. The effect of this subsection
6.3(d) shall be limited to determining the consequences of a termination and
nothing in this subsection 6.3(d) shall restrict or otherwise interfere with the
Company's discretion with respect to the termination of any person's employment
or other relationship. If the Committee does not so specify, the following shall
apply:

                           (i) If the employment or consulting relationship of
an Option Holder by or with the Company terminates for any reason other than
death or Disability within six months after the date the Option is granted or if
the employment or consulting relationship of the Option Holder by or with the
Company is terminated within the Option Period for cause, as determined by the
Company, the Option shall thereafter be void for all purposes. As used in this
subsection 6.3(d), "cause" shall mean a gross violation, as determined by the
Company, of the Company's established policies and procedures.

                           (ii) If the employment or consulting relationship of
the Option Holder terminates because the Option Holder becomes Disabled within
the Option Period, the Option may be exercised by the Option Holder (or, in the
case of his death after becoming disabled, by those entitled to

                                        6
<PAGE>

do so under his will or by the laws of descent and distribution) within one year
following such termination (if otherwise within the Option Period), but not
thereafter. In any such case, the Option may be exercised only as to the Shares
as to which the Option had become exercisable on or before the date of
termination because of Disability.

                           (iii) If the Option Holder dies within the Option
Period, while employed by the Company, while a consultant to the Company or
within the three-month period referred to in (iv) below, the Option may be
exercised by those entitled to do so under his will or by the laws of descent
and distribution within one year following the his death (if otherwise within
the Option Period), but not thereafter. In any such case the Option may be
exercised only as to the Shares as to which the Option had become exercisable on
or before the date of the Option Holder's death.

                           (iv) If the employment or consulting relationship of
the Option Holder by or with the Company terminates within the Option Period for
any reason other than for cause, Disability or death, and such termination
occurs more than six months after the Option is granted, any Incentive Option
may be exercised by the Option Holder within three months following the date of
such termination (if otherwise within the Option Period), but not thereafter,
and any Non-Qualified Option may be exercised by the Option Holder within one
year following the date of such termination (if otherwise within the Option
Period), but not thereafter.

                  (e) CONSIDERATION FOR GRANT OF OPTION. The Committee may
require each Eligible Employee who is granted an Option to agree to remain in
the employment of the Company, at the pleasure of the Company, for a continuous
period of at least six months after the date an Option is granted, at the salary
rate or other compensation in effect on the date of such agreement or at such
changed rate as may be fixed, from time to time, by the Company. Nothing in this
paragraph shall offset or impair the Company's right to terminate the employment
of any employee. The Committee may require each Eligible Consultant who is
granted an Option to agree to comply with all of the terms and conditions or
specified terms and conditions of the agreement between such Eligible Consultant
and the Company. If an Option Holder violates any such agreement,
UnitedGlobalCom may, in its sole discretion, rescind the transfer of any Shares
to the Option Holder pursuant to the exercise of any portion of the Option. Upon
notice of any such rescission, the Option Holder will deliver promptly to the
Company certificates representing the Shares, duly endorsed for transfer to the
Company.

                  (f) EXERCISE, PAYMENTS, ETC.

                           (i) MANNER OF EXERCISE. The method for exercising
each Option granted hereunder shall be by delivery to UnitedGlobalCom of written
notice specifying the number of Shares with respect to which such Option is
exercised. The purchase of such Shares shall take place at the principal offices
of UnitedGlobalCom within thirty days following delivery of such notice, at
which time the Option Price of the Shares shall be paid in full by any of the
methods set forth below or a combination thereof. Except as set forth in the
next sentence, the Option shall be exercised when the Option Price for the
number of shares as to which the Option is exercised is paid to UnitedGlobalCom
in full. If the Option Price is paid by means of a broker's loan transaction
described in subsection 6.3(f)(ii)(D), in whole or in part, the closing of the
purchase of the Stock under the Option shall take place (and the Option shall be
treated as exercised) on the date on which, and only if, the sale of Stock upon
which the broker's loan was based has been closed and settled, unless the Option
Holder makes an irrevocable written election, at the time of exercise of the
Option, to have the exercise treated as fully effective for all purposes upon

                                        7
<PAGE>

receipt of the Option Price by UnitedGlobalCom regardless of whether or not the
sale of the Stock by the broker is closed and settled. A properly executed
certificate or certificates representing the Shares shall be delivered to or at
the direction of the Option Holder upon payment therefor. If Options on less
than all shares evidenced by an Option Certificate are exercised,
UnitedGlobalCom shall deliver a new Option Certificate evidencing the Option on
the remaining shares upon delivery of the Option Certificate for the Option
being exercised.

                           (ii) MANNER OF PAYMENT. The exercise price shall be
paid by any of the following methods or any combination of the following methods
at the election of the Option Holder, or by any other method approved by the
Committee upon the request of the Option Holder:

                                    (A) in cash;

                                    (B) by certified check, cashier's check or
other check acceptable to the Company, payable to the order of UnitedGlobalCom;

                                    (C) by delivery to UnitedGlobalCom of
certificates representing the number of shares then owned by the Option Holder,
the Fair Market Value of which equals the purchase price of the Stock purchased
pursuant to the Option, properly endorsed for transfer to UnitedGlobalCom;
provided however, that no Option may be exercised by delivery to UnitedGlobalCom
of certificates representing Stock, unless such Stock has been held by the
Option Holder for more than six months or such other period as specified by the
Committee; for purposes of this Plan, the Fair Market Value of any shares of
Stock delivered in payment of the purchase price upon exercise of the Option
shall be the Fair Market Value as of the exercise date; the exercise date shall
be the day of delivery of the certificates for the Stock used as payment of the
Option Price; or

                                    (D) by delivery to UnitedGlobalCom of
irrevocable instructions to a broker to deliver to UnitedGlobalCom promptly the
amount of the proceeds of the sale of all or a portion of the Stock or of a loan
from the broker to the Option Holder required to pay the Option Price.

                  (g) DATE OF GRANT. An Option shall be considered as having
been granted on the date specified in the grant resolution of the Committee.

                  (h) WITHHOLDING.

                           (i) Non-Qualified Options. Upon exercise of an
Option, the Option Holder shall make appropriate arrangements with the Company
to provide for the amount of additional withholding required by Sections 3102
and 3402 of the Code and applicable state income tax laws, including payment of
such taxes through delivery of shares of Stock or by withholding Stock to be
issued under the Option, as provided in Article X.

                           (ii) Incentive Options. If an Option Holder makes a
disposition (as defined in Section 424(c) of the Code) of any Stock acquired
pursuant to the exercise of an Incentive Option prior to the expiration of two
years from the date on which the Incentive Option was granted or prior to the
expiration of one year from the date on which the Option was exercised, the
Option Holder shall send written notice to the Company at the Company's
principal place of business of the date of such

                                        8
<PAGE>

disposition, the number of shares disposed of, the amount of proceeds received
from such disposition and any other information relating to such disposition as
the Company may reasonably request. The Option Holder shall, in the event of
such a disposition, make appropriate arrangements with the Company to provide
for the amount of additional withholding, if any, required by Sections 3102 and
3402 of the Code and applicable state income tax laws.

         6.4 RESTRICTIONS ON INCENTIVE OPTIONS.

                  (a) INITIAL EXERCISE. The aggregate Fair Market Value of the
Shares with respect to which Incentive Options are exercisable for the first
time by an Option Holder in any calendar year, under the Plan or otherwise,
shall not exceed $100,000. For this purpose, the Fair Market Value of the Shares
shall be determined as of the date of grant of the Option.

                  (b) TEN PERCENT STOCKHOLDERS. Incentive Options granted to an
Option Holder who owns, directly and indirectly (within the meaning of Section
424(d) of the Code), 10% or more of the total combined voting power of all
classes of stock of UnitedGlobalCom shall have an Option Price equal to 110% of
the Fair Market Value of the Shares on the date of grant of the Option and the
Option Period for any such Option shall not exceed five years.

         6.5 SHAREHOLDER PRIVILEGES. No Option Holder shall have any rights as
a shareholder with respect to any shares of Stock covered by an Option until the
Option Holder becomes the holder of record of such Stock, and no adjustments
shall be made for dividends or other distributions or other rights as to which
there is a record date preceding the date such Option Holder becomes the holder
of record of such Stock, except as provided in Article IV.

                                   ARTICLE VII

                   CHANGE IN CONTROL; CORPORATE REORGANIZATION

         7.1 CHANGE IN CONTROL.

                  (a) If a Change in Control (as defined below) occurs under
(c)(i) below without the prior approval of at least a majority of the members of
the Board unaffiliated with such person or under (c)(ii) below, all Options
shall become exercisable in full, regardless of whether all conditions of
exercise relating to length of service have been satisfied and shall remain so,
whether or not Option Holder remains an employee or consultant of the Company.

                  (b) If a Change in Control (as defined below) occurs under
(c)(i) below with the prior approval of at least a majority of the members of
the Board unaffiliated with such person and (i) the Option Holder's employment
is terminated within six (6) months after such Change of Control or (ii) the
Option Holder is assigned duties materially different in any respect to such
Option Holder's duties, authority or responsibilities prior to such Change of
Control, all Options shall become exercisable in full, regardless of whether all
conditions of exercise relating to length of service have been satisfied and
shall remain so, whether or not Option Holder remains an employee or consultant
of the Company.

                                        9
<PAGE>

                  (c) "Change in Control" is deemed to have occurred if (i) a
person (as such term is used in Section 13(d) of the Exchange Act) becomes the
beneficial owner (as defined in Rule 13d-3 under the Exchange Act) of shares of
UnitedGlobalCom having more than 50% of the total number of votes that may be
cast for the election of directors of UnitedGlobalCom and after such acquisition
such person has the ability, through share ownership contract or otherwise, to
elect persons constituting a majority of the Board; or (ii) individuals who
constitute the directors of UnitedGlobalCom at the beginning of a 24-month
period (together with any new or replacement directors as approved by a vote of
at least a majority of the members of the Board in office immediately prior to
such period and of the new and replacement directors so approved) cease to
constitute at least 2/3 of all directors at any time during such period;
provided, however, any increased ownership by Liberty Media Corporation or its
wholly-owned subsidiaries pursuant to the terms set forth in that certain
Agreement dated as of May 25, 2001, among UnitedGlobalCom, Liberty Media
Corporation and Liberty Media International, Inc., shall not be deemed a Change
in Control for purposes of this Plan.

         7.2 REORGANIZATION. If a Change in Control has not occurred and one of
the following events has occurred and if the notice required by Section 7.3
shall have first been given, the Plan and all Options then outstanding hereunder
shall automatically terminate and be of no further force and effect whatsoever,
without the necessity for any additional notice or other action by the Board or
UnitedGlobalCom: (a) the merger or consolidation of UnitedGlobalCom with or into
another corporation (other than a consolidation or merger in which
UnitedGlobalCom is the continuing corporation and which does not result in any
reclassification or change of outstanding shares of stock; or (b) the sale or
conveyance of the property of UnitedGlobalCom as an entirety or substantially as
an entirety (other than a sale or conveyance in which UnitedGlobalCom continues
as holding company of an entity or entities that conduct the business or
business formerly conducted by UnitedGlobalCom); or (c) the dissolution or
liquidation of UnitedGlobalCom.

         7.3 REQUIRED NOTICE. At least 30 days' prior written notice of any
event described in Section 7.2 shall be given by UnitedGlobalCom to each Option
Holder, unless in the case of the events described in clauses (a) or (b) of
Section 7.2, UnitedGlobalCom, or the successor or purchaser, as the case may be,
shall make adequate provision for the assumption of the outstanding Options or
the substitution of new options for the outstanding Options on terms comparable
to the outstanding Options, except that the Option Holder shall have the right
thereafter to purchase the kind and amount of securities or property or cash
receivable upon such merger, consolidation, sale or conveyance by a holder of
the number of Shares that would have been receivable upon exercise of the Option
immediately prior to such merger, consolidation, sale or conveyance (assuming
such holder of Stock failed to exercise any rights of election and received per
share the kind and amount received per share by a majority of the non-electing
shares). The provisions of this Article VII shall similarly apply to successive
mergers, consolidations, sales or conveyances. Such notice shall be deemed to
have been given when delivered personally to an Option Holder or when mailed to
an Option Holder by registered or certified mail, postage prepaid, at such
Option Holder's address last known to the Company.

         7.4 ACCELERATION OF EXERCISABILITY. Option Holders notified in
accordance with Section 7.3 may exercise their Options at any time before the
occurrence of the event requiring the giving of notice (but subject to
occurrence of such event), regardless of whether all conditions of exercise
relating to length of service have been satisfied.

                                  ARTICLE VIII

                           EMPLOYMENT; TRANSFERABILITY

         8.1 SERVICE. Nothing contained in the Plan or in any Option granted
under the Plan shall confer upon any Option Holder any right with respect to the
continuation of his employment by, or consulting relationship with, the Company,
or interfere in any way with the right of the Company, subject to the terms of
any separate employment agreement or other contract to the contrary, at any time
to terminate such services or to increase or decrease the compensation of the
Participant from the rate in existence at the time of the grant of an Option.
Whether an authorized leave of absence, or absence in military or government
service, shall constitute a termination of service shall be determined by the
Committee at the time of its occurrence.

         8.2 OTHER EMPLOYEE BENEFITS. The amount of any compensation deemed to
be received by an Option Holder as a result of the exercise of an Option shall
not constitute "earnings" with respect to which any other employee benefits of
such person are determined, including without limitation benefits under any
pension, profit sharing, life insurance or salary continuation plan.

         8.3 TRANSFERABILITY.

                  (a) GENERAL RULE: NO LIFETIME TRANSFERS. An Option shall not
be transferable by the Option Holder except by will or pursuant to the laws of
descent and distribution. An Option shall be exercisable during the Option
Holder's lifetime only by him or her, or in the event of Disability or
incapacity, by his or her guardian or legal representative. The Option Holder's
guardian or legal representative shall have all of the rights of the Option
Holder under this Plan.

                  (b) INTERVIVOS TRANSFER TO CERTAIN FAMILY MEMBERS. The
Committee may, however, provide at the time of grant or thereafter that the
Option Holder may transfer a Non-Qualified Option to a member of the Option
Holder's immediate family, a trust of which members of the Option Holder's
immediate family are the only beneficiaries, or a partnership of which members
of the Option Holder's immediate family or trusts for the sole benefit of the
Option Holder's immediate family are the only partners (the "InterVivos
Transferee"). Immediate family means the Option Holder's spouse, issue (by birth
or adoption), parents, grandparents, siblings (including half brothers and
sisters and adopted siblings) and nieces and nephews. No transfer shall be
effective unless the Option Holder shall have notified the Company of the
transfer in writing and has furnished a copy of the documents that effect the
transfer to the Company. The InterVivos Transferee shall be subject to all of
the terms of this Plan and the Option, including, but not limited to, the
vesting schedule, termination provisions, and the manner in which the Option may
be exercised. The Committee may require the Option Holder and the InterVivos
Transferee to enter into an appropriate agreement with the Company providing
for, among other things, the satisfaction of required tax withholding with
respect to the exercise of the transferred Option and the satisfaction of any
Stock retention requirements applicable to the Option Holder, together with such
other terms and conditions as may be specified by the Committee. Except to the
extent provided otherwise in such agreement, the InterVivos Transferee shall
have all of the rights and obligations of the Option Holder under this Plan;
provided that the InterVivos Transferee shall not have any Stock withheld to pay
withholding taxes pursuant to Section 10.2 unless the agreement referred to in
the preceding sentence specifically provides otherwise.

                                       11
<PAGE>

                  (c) NO TRANSFER OF ISOS. During the Option Holder's lifetime
the Option Holder may not transfer an Incentive Option under any circumstances.

                  (d) NO ASSIGNMENT. No right or interest of any Option Holder
in an Option granted pursuant to the Plan shall be assignable or transferable
during the lifetime of the Option Holder, either voluntarily or involuntarily,
or be subjected to any lien, directly or indirectly, by operation of law, or
otherwise, including execution, levy, garnishment, attachment, pledge or
bankruptcy, except as set forth above.

                                   ARTICLE IX

                              GENERAL RESTRICTIONS

         9.1 INVESTMENT REPRESENTATIONS. UnitedGlobalCom may require any person
to whom an Option is granted, as a condition of exercising such Option, to give
written assurances in substance and form satisfactory to UnitedGlobalCom and its
counsel to the effect that such person is acquiring the Stock for his own
account for investment and not with any present intention of selling or
otherwise distributing the same, and to such other effects as UnitedGlobalCom
deems necessary or appropriate in order to comply with Federal and applicable
state securities laws. Legends evidencing such restrictions may be placed on the
Stock certificates.

         9.2 COMPLIANCE WITH SECURITIES LAWS. Each Option shall be subject to
the requirement that, if at any time counsel to UnitedGlobalCom shall determine
that the listing, registration or qualification of the shares subject to such
Option upon any securities exchange or under any state or federal law, or the
consent or approval of any governmental or regulatory body, is necessary as a
condition of, or in connection with, the issuance or purchase of shares
thereunder, such Option may not be accepted or exercised in whole or in part
unless such listing, registration, qualification, consent or approval shall have
been effected or obtained on conditions acceptable to the Committee. Nothing
herein shall be deemed to require UnitedGlobalCom to apply for or to obtain such
listing, registration or qualification.

         9.3 CHANGES IN ACCOUNTING RULES. Except as provided otherwise at the
time an Option is granted, notwithstanding any other provision of the Plan to
the contrary, if, during the term of the Plan, any changes in the financial or
tax accounting rules applicable to Options shall occur which, in the sole
judgment of the Committee, may have a material adverse effect on the reported
earnings, assets or liabilities of the Company, the Committee shall have the
right and power to modify as necessary, any then outstanding and unexercised
Options as to which the applicable services or other restrictions have not been
satisfied.

                                    ARTICLE X

                                   WITHHOLDING

         10.1 WITHHOLDING REQUIREMENT. UnitedGlobalCom's obligations to deliver
shares of Stock upon the exercise of any Option shall be subject to the Option
Holder's satisfaction of all applicable federal, state and local income and
other tax withholding requirements.

                                       12
<PAGE>

         10.2 WITHHOLDING WITH STOCK. At the time the Committee grants an
Option or at any time thereafter, it may, in its sole discretion, grant the
Option Holder an election to pay all such amounts of tax withholding, or any
part thereof, by electing (a) to have UnitedGlobalCom withhold from shares
otherwise issuable to the Option Holder, shares of Stock having a value equal to
the amount required to be withheld or such lesser amount as may be elected by
the Option Holder; provided however, that the amount of Stock so withheld shall
not exceed the minimum amount required to be withheld under the method of
withholding that results in the smallest amount of withholding, or (b) to
transfer to UnitedGlobalCom a number of shares of Stock that were acquired by
the Option Holder more than six months prior to the transfer to UnitedGlobalCom
and that have a value equal to the amount required to be withheld or such lesser
amount as may be elected by the Option Holder. All elections shall be subject to
the approval or disapproval of the Committee. The value of shares of Stock to be
withheld shall be based on the Fair Market Value of the Stock on the date that
the amount of tax to be withheld is to be determined (the "Tax Date"). Any such
elections by Option Holders to have shares of Stock withheld for this purpose
will be subject to the following restrictions:

                  (a) All elections must be made prior to the Tax Date.

                  (b) All elections shall be irrevocable.

                  (c) If the Option Holder is an officer or director of
UnitedGlobalCom within the meaning of Section 16 of the 1934 Act ("Section 16"),
the Option Holder must satisfy the requirements of such Section 16 and any
applicable Rules thereunder with respect to the use of Stock to satisfy such tax
withholding obligation.

                                   ARTICLE XI

                                  MISCELLANEOUS

         11.1 EXPIRATION. The Plan shall terminate whenever the Board adopts a
resolution to that effect. If not sooner terminated by the Board, the Plan shall
terminate and expire on June 1, 2003. After termination, no additional Options
shall be granted under the Plan, but the Company shall continue to recognize
Options previously granted.

         11.2 AMENDMENTS, ETC. The Board may from time to time amend, modify,
suspend or terminate the Plan. Nevertheless, no such amendment, modification,
suspension or termination shall, without the consent of the Option Holder,
impair any Option previously granted under the Plan or deprive any Option Holder
of any Shares that he may have acquired through or as a result of the Plan.

         11.3 TREATMENT OF PROCEEDS. Proceeds from the sale of Stock pursuant
to Options granted under the Plan shall constitute general funds of
UnitedGlobalCom.

         11.4 SECTION HEADINGS. The section headings are included herein only
for convenience, and they shall have no effect on the interpretation of the
Plan.

         11.5 SEVERABILITY. If any article, section, subsection or specific
provision is found to be illegal or invalid for any reason, such illegality or
invalidity shall not affect the remaining provisions of the Plan, and the Plan
shall be construed and enforced as if such illegal and invalid provision had
never been set forth in the Plan.

         11.6 GENDER AND NUMBER. Except when otherwise indicated by the
context, the masculine gender shall include the feminine gender, and the
definition of any term herein in the singular shall also include the plural.
