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:

     (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

------------

(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.
                                        1

     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, 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

                                        2
<PAGE>

     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.

     (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.

(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.
