                                  SCHEDULE 13D
                               (Amendment No. 3)

                                  Statement of

                           TELE-COMMUNICATIONS, INC.

                        Pursuant to Section 13(d) of the
                        Securities Exchange Act of 1934

                                 in respect of

                                    DMX INC.
                         (Commission File No. 0-18806)


ITEM 1.  Security and Issuer

         Tele-Communications, Inc., a Delaware corporation ("TCI"), hereby
amends and supplements its Statement on Schedule 13D (the "Statement"), with
respect to the common stock, $.01 par value (the "Common Stock"), of DMX Inc.,
a Delaware corporation ("DMX").  DMX's principal executive offices are located

Pursuant to Rule 13d-2(c) of the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), this Amendment No. 3 also restates the Statement and each
subsequent amendment.


ITEM 2.  Identity and Background

         This Amendment No. 3 is being filed by TCI whose principal business
address is 5619 DTC Parkway, Englewood, Colorado 80111.

         TCI, through its subsidiaries and affiliates, is principally engaged in

business since the early 1950's.  Prior to August 1994, TCI was named
TCI/Liberty Holding Company and TCIC was named Tele-Communications, Inc.

         Schedule 1 attached to this Amendment No. 3 to the Statement contains
the following information concerning each director, executive officer or
controlling person of TCI:  (i) name and residence or business address, (ii)
principal occupation or employment; and (iii) the name, principal business and
address of any corporation or other organization in which such employment is
conducted.  Schedule 1 is incorporated herein by reference and replaces the
Schedule previously filed with the Statement.

         To the knowledge of TCI, each of the persons named on Schedule 1 (the
"Schedule 1 Persons") is a United States citizen.  During the last five years,
neither TCI nor any of the Schedule 1 Persons (to the knowledge of TCI) has
been convicted in a criminal proceeding (excluding traffic violations or
similar misdemeanors).  During the last five years, neither TCI nor any of the
Schedule 1 Persons (to the knowledge of TCI) has been a party to a civil
proceeding of a judicial or administrative body of competent jurisdiction and,
as a result of such proceeding, is or was subject to a judgment, decree or
final order enjoining future violations of, or prohibiting or mandating
activities subject to, federal or state securities laws or finding any
violation with respect to such laws.

August 1994 Business Combination

         On August 4, 1994, at Special Meetings of Stockholders of TCIC and
Liberty Media Corporation ("LMC"), there was approved and adopted an Agreement
and Plan of Merger, dated as of January 27, 1994, as amended, which provided
for, among other things, the business combination of TCIC and LMC resulting in
the companies becoming wholly owned subsidiaries of TCI (the "Business
Combination").  The Business Combination became effective on August 4, 1994
upon certain filings with state authorities.  Upon the effectiveness of the
Business Combination, TCI became the indirect beneficial owner of all of the
Common Stock owned by TCIC.

         The foregoing summary of the Business Combination is qualified in its
entirety by reference to the complete terms, provisions and conditions thereof
set forth in the Proxy Statement of LMC and TCIC and the Prospectus of TCI
filed on June 23, 1994 (the "Proxy Statement/Prospectus") by such parties as
part of Registration Statement on Form S-4 (No. 33-54263).  The Registration
Statement and Proxy Statement/Prospectus were incorporated herein by reference
and were so filed herewith as Exhibit A in the original Statement.


ITEM 3.  Source and Amount of Funds or Other Consideration

         TCI currently beneficially owns, directly and through certain of its
subsidiaries, 27,100,687 shares of the Common Stock.  The Common Stock was

reported transactions and in connection with three recent transactions.  The
information set forth below describes the previously reported and recent
transactions and states the source and amount of the consideration used in the
transactions.

Acquisition Pursuant to the Business Combination

        In connection with the Business Combination described in Item 2 above,
TCI acquired indirect beneficial ownership of 3,409,063 shares of the Common
Stock.  The consideration for the acquisition of such Common Stock was the
consideration given in the Business Combination which is described in the Proxy
Statement/Prospectus under the heading "THE MERGER AGREEMENT -- Consideration
to be Received in the Mergers".

August 1995 Purchase of the Common Stock

        TCI used its working capital as the source of the funds for the
acquisition of 2,000,000 shares of the Common Stock purchased by TCI Turner
Preferred, Inc. on August 29, 1995 (the "August 1995 Securities").  The August
1995 Securities were purchased for a total cash purchase price of $5,000,000.

January 1996 Purchase of the Common Stock

        TCI used its working capital as the source of the funds for the
acquisition of 650,000 shares of the Common Stock purchased by TCI on January
2, 1996 and January 8, 1996 (the "January 1996 Securities").  The January 1996
Securities were purchased in three transactions for a total cash purchase price
of $1,520,918.  On January 2, 1996, TCI purchased 340,000 shares of the Common
Stock for $2.31 per share for a total purchase price of $786,250. On January 8,
1996, TCI purchased 140,000 shares of the Common Stock for $2.4062 per share
for a total purchase price of $336,868.  On January 8, 1996, TCI purchased
170,000 shares of the Common Stock for $2.34 per share for a total purchase
price of $397,800.

May 1996 Acquisitions of the Common Stock

        TCI used its working capital as the source of the funds for the
acquisition on May 17, 1996 of 5,700,000 shares of the Common Stock from
Stephen A. Wynn.  The acquisition was pursuant to a Stock Purchase Agreement,
dated as of May 13, 1996, between Mr. Wynn and TCI.  A copy of the Stock
Purchase Agreement is attached hereto as Exhibit 7(B) and is hereby
incorporated by reference.  Such shares were purchased for $2 per share for a
total cash purchase price of $11,400,000.

        Additionally, TCI used its working capital as the source of the funds
for the acquisition on May 17, 1996 of 4,500,000 shares of the Common Stock
from DMX.  The acquisition was pursuant to a Stock Purchase Agreement, dated as
of May 14, 1996, between DMX and TCI.  A copy of the Stock Purchase Agreement
is attached hereto as Exhibit 7(C) and is hereby

incorporated by reference.  Such shares were purchased for $2 per share for a
total cash purchase price of $9,000,000.  The Common Stock acquired in these
two transactions shall be referred to herein as the "May 1996 Securities".
        
        In addition, United Artists Programming International, Inc., an
indirect majority owned subsidiary of TCI ("UAPI"), acquired 10,841,624 shares
of the Common Stock from DMX in connection with a merger (the "Merger")
pursuant to the terms of an Agreement and Plan of Merger, dated as of August
28, 1995, as amended, among DMX, TCI-Euromusic, Inc. ("TCI-E"), and UAPI (the
"Merger Agreement").  The Merger Agreement is attached hereto as Exhibit 7(D) 
and is hereby incorporated by reference.

        In connection with the Merger, TCI-E was merged with and into DMX and
DMX was the surviving corporation in the Merger.  The Merger was effective as
of May 17, 1996.

        Prior to the Merger, UAPI owned all of the outstanding shares of common
stock of TCI-E.  As consideration in the Merger for such ownership interest in
TCI-E, UAPI received 10,841,624 shares of the Common Stock in exchange for all
of the shares of TCI-E common stock.  In addition, two promissory notes in the
aggregate principal amount of $24,637,091 owed by DMX-Europe N.V. ("DMX-E") to
TCI-E were canceled.  Prior to the Merger, DMX owned 51% and TCI-E owned 49% of
the issued and outstanding shares of DMX-E.


ITEM 4. Purpose of Transaction

        In connection with the Merger, Tele-Communications International, Inc.,
a majority owned subsidiary of TCI, received the right to appoint two directors
to the board of directors of DMX.  Donne F. Fisher and Leo J. Hindery, Jr. were
appointed to the board of DMX to satisfy this requirement and to fill immediate
vacancies created by the resignations of Stephen A. Wynn and W. Thomas Oliver. 
Donne Fisher currently serves as a director of TCI and serves as a consultant
to TCI.  Mr. Fisher served as an officer of TCI until January 1996. 
Additionally, Mr. Hindery serves as chief executive officer of InterMedia
Partners, a multi-system cable television operator.  TCI has various
investments in InterMedia Partners and its related entities.

        In addition, there is an informal, non-binding understanding between
TCI and a majority of the existing directors of DMX that TCI may recommend the
appointment of two additional candidates for election to the board of 
directors of DMX.  TCI plans to exercise its right to recommend the appointment
of such candidates in the near future.

        Additionally, due to the current financial condition of DMX, management
of DMX and the board of directors of DMX are continually reviewing alternatives
and strategies for improving the financial performance of DMX.  No assurance
can be given that the outcome of this review by DMX management will not require
a change in TCI's present investment in DMX or require an extraordinary
corporate transaction as described in the next paragraph.

<PAGE>   7
Cusip No. 23323Q104



        Except as otherwise described herein, neither TCI nor, to the best of
its knowledge, any of its executive officers, directors or controlling persons,
have any present plans or proposals which relate to or would result in:  (i)
any acquisition by any person of additional securities of DMX, or any
disposition of securities of DMX; (ii) any extraordinary corporate transaction,
such as a merger, reorganization or liquidation, involving DMX or any of its
subsidiaries; (iii) any sale or transfer of a material amount of assets of DMX
or any of its subsidiaries; (iv) any change in the present board of directors
or management of DMX, including any plans or proposals to change the number or
term of directors or to fill any existing vacancies on the board; (v) any
material change in the present capitalization or dividend policy of DMX; (vi)
any other material change in DMX's business or corporate structure; (vii) any
changes in DMX's charter, by-laws, or other instruments corresponding thereto
or other actions which may impede the acquisition of control of DMX by any
person; (viii) any delisting from a national securities exchange or any loss of
authorization for quotation in an inter-dealer quotation system of a registered
national securities association of a class of securities of DMX; (ix) any
termination of registration pursuant to section 12(g)(4) of the Exchange Act of
a class of equity securities of DMX; or (x) any action similar to any of those
enumerated above.

        Notwithstanding the foregoing paragraph, TCI may determine to change
its investment intent with respect to DMX at any time in the future.  In
reaching any conclusion as to its future course of action, TCI will take into
consideration various factors, such as DMX's business and prospects, other
developments concerning DMX, other business opportunities available to TCI,
developments with respect to the business of TCI, and general economic and
stock market conditions, including, but not limited to, the market price of the
Common Stock of DMX.  TCI reserves the right, depending on other relevant
factors, to acquire additional shares of the Common Stock of DMX in open market
or privately negotiated transactions, to dispose of all or a portion of its
holdings of shares of the Common Stock of DMX or to change its intention with
respect to any or all of the matters referred to in this Item.

                            STOCK PURCHASE AGREEMENT

        This STOCK PURCHASE AGREEMENT (the "Agreement") is entered into as of
the 13th day of May, 1996 by and between TELE-COMMUNICATIONS, INC., a Delaware
corporation (the "Purchaser") and STEPHEN A. WYNN (the "Seller").

                                    RECITALS

        WHEREAS, an affiliate of Purchaser and Seller are currently
shareholders of DMX Inc., a Delaware corporation (the "Company"); and

        WHEREAS, on the terms and subject to the conditions contained herein,
Purchaser desires to purchase 5,700,000 shares of the Company's common stock
("the Shares") from the Seller; and

        WHEREAS, the Seller desires to sell all, but not less than all, of the
Shares to Purchaser.

        NOW, THEREFORE, in consideration of the above premises and of the
mutual covenants and agreements contained herein, and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged,
Purchaser and the Company do hereby agree as follows:

        1.       Purchase and Sale of the Shares. On the terms and subject to
the conditions contained herein, Purchaser shall purchase from Seller, and
Seller shall sell to the Purchaser, the Shares for the amount of $11,400,000
(the "Purchase Price").

        2.       Closing. The closing of the purchase and sale of the Shares
(the "Closing") shall be held at the offices of Irell & Manella, 1800 Avenue of
the Stars, Los Angeles, CA, or at such other location as is agreed by the
parties, as soon as practicable following the execution of this Agreement and
in all events, not later than the later of the satisfaction of the conditions
to the parties' obligations hereunder and the date on which the Company's
merger with TCI-Euromusic, Inc. is consummated. The purchase shall be completed
by (i) Seller's delivery of certificates evidencing the Shares together with
stock powers sufficient to cause the Shares to be transferred to the name of
Purchaser or its designee, and (ii) Purchaser's delivery to Seller by wire
transfer of the Purchase Price pursuant to the instructions previously
delivered to Purchaser. If the Closing has not occurred prior to June 1, 1996,
then either party may terminate this Agreement; provided, however, that no
party may so terminate this Agreement if that party is in default of its
obligations hereunder.

                     REPRESENTATIONS AND WARRANTIES OF DMX

                 DMX hereby represents and warrants to the Investor as follows:

                 2.1      Organization. DMX is a corporation duly organized,
validly existing and in good standing under the laws of Delaware and has the
requisite corporate power and authority to own, lease and operate its
properties and to carry on its business in the manner now being conducted and
is duly qualified or licensed to do business as a foreign corporation in good
standing in all the jurisdictions in which the ownership of its property or the
conduct of its business requires such qualification, except such jurisdictions
in which its failure to be so qualified or licensed will have no material
adverse effect on its financial condition, results of operations, liabilities,
assets or business.
<PAGE>   2
                 2.2      Corporate Power and Authority of DMX. DMX has the 
full corporate power and authority to execute and deliver this Agreement and 
to perform its obligations under this Agreement. The execution, delivery and
performance of this Agreement by DMX have been authorized by all necessary
corporate actions required by law, DMX's Certificate of Incorporation or its
Bylaws or otherwise required to be taken to authorize the execution, delivery
and performance of this Agreement and the consummation of the transactions
contemplated hereby. This Agreement is a valid and binding agreement of DMX,
enforceable in accordance with its terms, except that enforceability of Section
4.7 hereof may be subject to limitations of public policy under federal and
state securities laws.

                 2.3      No Breach. The execution and delivery of this
Agreement by DMX do not, and the performance by DMX of its obligations under,
and the consummation by DMX of the transactions contemplated by, this Agreement
will not, (a) violate or conflict with the Certificate of Incorporation or
Bylaws of DMX, (b) in any material respect, constitute a breach or default (or
an event that with notice or lapse of time or both would become a breach or
default) or give rise to any lien or any third-party right of termination,
cancellation, modification or acceleration under any instrument or agreement to
which DMX is a party or by which DMX or any of its assets is bound or (c)
in any material respect, constitute a violation of any statute, law, ordinance,
rule or regulation.

                 2.4      Governmental Consents and Approvals. Neither the
execution and delivery of this Agreement by DMX nor the consummation of the
transactions contemplated by this Agreement by DMX will require any consent,
approval, authorization or permit of, or filing with or notification to, any
Governmental Authority.

                 2.5      Capital Structure. At the date hereof, the authorized
capital stock of DMX consists of (i) 100,000,000 shares of common stock, $.01
par value (the "Common Stock"), of which 44,244,970 shares are issued and
outstanding. As is more fully described on Exhibit A hereto, as of the date of
this Agreement there are also outstanding options and rights to purchase
4,330,833 shares of Common Stock. All of the Shares to be issued pursuant to
this Agreement, when issued in accordance with the terms of the Agreement, will
be duly authorized, validly issued, fully paid and nonassessable. Except as set
forth in Exhibit A, there are no outstanding subscriptions, options, calls,
rights, warrants, convertible securities, unsatisfied preemptive rights or
other agreements or commitments of any character obligating DMX to issue (or
reserve for issuance) or to transfer or sell any shares of its capital stock of
any class.

                 2.6      SEC Filing. DMX has heretofore furnished the Investor
with a complete copy of DMX's Annual Report on Form 10-K for its fiscal year

for the fiscal quarter ended December 31, 1995, a Quarterly Report on Form 10-Q
for the fiscal quarter ended March 31, 1996 (the "March 10-Q"), and a
definitive proxy statement (the "Proxy Statement") for DMX's Meeting of
Stockholders held on March 12, 1996 (collectively, the "SEC Filings"), which
have previously been filed with the Securities and Exchange Commission ("SEC").
The SEC Filings when filed with the SEC complied in all material respects with
the Securities Exchange Act of 1934, as amended (the "Exchange Act")





                                      -2-

and the rules and regulations thereunder. The March 10-Q is the only regular or
periodic report required to be filed by DMX pursuant to Sections 13 and 14 of
the Exchange Act with the SEC since March 31, 1996. The Annual Report
describes, among other things, the business, operations and principal
properties of DMX in accordance with the requirements of the applicable report
form. As of the date of their filing, the SEC Filings did not contain any
untrue statement of a material fact or omit to state any material fact
necessary in order to make the statements therein not misleading. Except as
disclosed in the SEC Filings, since March 31, 1996, there have been no material
changes in the business, results of operations, financial condition or
properties of DMX required to be reported to the SEC pursuant to the Exchange
Act as of the Closing.

          loans to, Guaranteed any obligations of, or made any equity 
          investments in any person, except for loans, guarantees, obligations

                                  ARTICLE III
                 REPRESENTATIONS AND WARRANTIES OF THE INVESTOR

          The Investor represents and warrants to DMX as follows:

          3.1      Authorization. This Agreement has been duly authorized,
executed and delivered by the Investor and constitutes its valid and legally
binding obligation.

          3.2      Investment Representation. The Investor is acquiring the
Shares as principal for its own account and not with a view to, or for sale in
connection with, any distribution thereof, nor with any present intention of
selling or otherwise disposing of same.

          3.3      Receipt of Information. The Investor and its representatives
have reviewed this Agreement, and all Exhibits hereto, the SEC Filings and all
other documents and materials DMX has provided to it in connection with the
transactions contemplated by this Agreement. The Investor and its
representatives have had access to and an opportunity to review all documents
and other materials requested of DMX and have been given an opportunity to ask
such questions of DMX concerning the terms and conditions of the sale of the
Shares and the business, operations, financial condition, assets and liabilities
of DMX and other relevant matters as they have deemed necessary or desirable and
have been given all such information as they have requested, in order to
evaluate the merits and risks of the investment contemplated herein.

          3.4      Brokers. The Investor has not entered into any agreement for
the payment of any broker's or finder's fee or commission in connection with the

<PAGE>   5
          3.5      Private Placement. The Investor understands that the Shares
have not been registered under the United States Securities Act of 1933 (the
"1933 Act") or registered or qualified under any state securities laws on the
grounds that such Shares are being issued in a transaction exempt from the
registration requirements of the 1933 Act and the registration or qualification
requirements of applicable state securities laws, and that the Shares must be
held indefinitely unless such Shares are subsequently registered under the 1933
Act and qualified or registered under applicable state securities laws or an
exemption from registration and qualification is available, and that, except as
otherwise provided in this Agreement, DMX is under no obligation to register or
qualify the Shares. DMX may require an opinion of the Investor's counsel prior
to authorizing the registration of any transfer of Shares in reliance on an
exemption from registration or qualification to the effect that the transfer is
exempt from such registration or qualification. The Investor shall hold harmless
DMX and its directors, officers, employees and agents against any loss or
liability from any disposition of Shares by it in violation of this Section 3.5.

          3.6      Principal Office. The location of the Investor's principal
executive and business office is at the Investor's address set forth in Section
5.5 below.

within the meaning of Rule 501 of Regulation D promulgated under the 1933 Act
and has such knowledge and experience in financial and business matters that it
is capable of evaluating the merits and risks of the investment to be made
hereunder by it and it is able to bear the economic risk of its investment. The
Investor (i) has total assets in excess of $5,000,000, (ii) was not formed for
the purpose of investing in the Shares, and (iii) has business or investments
other than the investment in the Shares.

          3.8      Preexisting Relationship. The Investor either (i) has a
preexisting personal or business relationship with DMX or any of its officers,
directors or controlling persons or an affiliate of DMX, or (ii) by reason of
its business or financial experience or the business or financial experience of
its professional advisor(s) who is (are) unaffiliated with and who is (are) not
compensated, directly or indirectly, by DMX, or any affiliate or selling agent
of DMX, the Investor can reasonably be assumed to have the capacity to protect
its own interests in connection with this transaction.

          3.9      Legends. The Investor acknowledges that each certificate or
other document evidencing the Shares shall be endorsed with the legends set
forth below:

                   (a)  "THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED
                         UNDER THE UNITED STATES SECURITIES ACT OF 1933, AND 
                         MAY NOT BE SOLD, TRANSFERRED, ASSIGNED, PLEDGED OR

                         TO AUTHORIZE ANY TRANSFER OF THE SHARES IN RELIANCE
                         ON AN EXEMPTION FROM REGISTRATION UNTIL IT HAS 
                         RECEIVED AN OPINION OF COUNSEL, REASONABLY
                         SATISFACTORY TO THE COMPANY AND ITS COUNSEL, THAT SUCH
                         REGISTRATION IS NOT REQUIRED."

                    (b)  If required by the authorities of any state in
                         connection with the issuance or sale of the Shares,

          3.9      Confidentiality. The Investor shall keep confidential
and shall not use the Confidential Information provided to it by DMX or Its
agents in connection with the transactions contemplated hereby. As used herein,
the term "Confidential Information" shall mean any trade secrets or nonpublic
information of DMX which has been designated as such by DMX prior to its
disclosure to Investor. The foregoing notwithstanding, Confidential Information
will not be deemed to include (1) information in Investor's possession,
otherwise than as a result of Investor's confidential or fiduciary relationship
with DMX, prior to the disclosure thereof by DMX, (11) information which is in
the public domain through no act or omission of Investor, (iii) information
which is disclosed to Investor by a third party which did not acquire the
information under an obligation of confidentiality, or (iv) information which

                                   ARTICLE IV
                              REGISTRATION RIGHTS

          4.1     Pendent Registration Rights.

                  (a)      If at any time during the period beginning on the
date of the Closing and ending on the third anniversary of the Closing, DMX
proposes to file, on its behalf and/or on behalf of any of its securities
holders, a new registration statement relating to the Common Stock of DMX under
the 1933 Act (a "Registration Statement") other than in connection with (i) a
dividend reinvestment, employee stock purchase, option or similar plan, (ii) a
merger, consolidation or reorganization or (iii) a rights offering to
stockholders, DMX shall give written notice to the Investor at least 30 days
before the filing with the SEC of such Registration Statement. Such notice
shall offer to include in such filing that number of Registrable Shares (as
defined herein) then held by the Investor as the Investor may request pursuant
to written notice to DMX within 20 days after the date of mailing of such
offer, stating, in such request the intended method of distribution of such
Registrable Shares. DMX shall thereupon include in such filing that amount of
the Investor's Registrable Shares so requested by the Investor and, subject to
its right to withdraw such filing, shall use its best efforts to effect
registration under the 1933 Act of such Registrable Shares. For purposes of
this Article IV, any rights in respect of the Registrable Shares granted to the
Investor shall also be available to any person controlled by, controlling, or
under common control with the Investor (an


                                      -6-
<PAGE>   7
"Affiliate"). As used herein, "Registrable Shares" means the Shares and any
other shares of Common Stock held by the Investor or an Affiliate, and all
references in this Article IV to the Investor will be deemed to be applicable
to an Affiliate that holds Registrable Shares.

                 (b)      The right of the Investor to have its Registrable
Shares included in any Registration Statement in accordance with the provisions
of this Section 4.1 shall be subject to the following conditions:

                 (i)      the number of occasions on which registration may be
requested shall be unlimited.

                 (ii)     Investor may not request the registration pursuant to
this Section 4.1 of less than an aggregate of 10,000 Registrable Shares
(subject to splits and combinations after the date hereof (unless the Investor
is requesting registration of all Registrable Shares then held by DMX and its
Affiliates) pursuant to any one Registration Statement; and

                 (iii)    if such registration shall be in connection with an
underwritten public offering and if the managing underwriters shall advise DMX
in writing that in their good faith opinion the number of securities requested
to be included in such Registration Statement exceeds the number which can be
sold in an orderly manner in such offering, DMX shall include in such
registration, first, securities which DMX proposes to sell, if any, or if none
of the securities will be registered for sale by DMX, the securities requested
to be registered by the shareholder(s) initially requesting such registration,
second, securities which other shareholders of DMX with registration rights
granted prior to the date hereof which are superior to those of the Investor
propose to sell, and third, the Registrable Shares requested to be included in
such Registration Statement by the Investor and other shareholders with
registration rights not superior to the Investor, pro rata among the Investor
and such other shareholders (if all such Common Stock may not be sold) on the
basis of the number of shares of Common Stock owned by the Investor and such
other shareholders.

                 (c)      Notwithstanding the foregoing, DMX in its sole
discretion may determine not to file the Registration Statement or to delay the
offering as to which the notice specified herein is given and, thereupon, shall
be relieved of its obligation to register or shall be permitted to delay
registering, as the case may be, any Registrable Shares requested to be
included therein without any liability to the Investor.

                 (d)      Any request by the Investor to include Registrable
Shares in a Registration Statement shall express the Investor's present intent
to offer the Registrable Shares to be included in the Registration Statement
for distribution and contain an undertaking to provide all such information and
materials and to take all such actions as may be required in order to permit
DMX to comply with all applicable requirements of the SEC (including disclosure
in writing to DMX of the method or methods of distribution contemplated by the
Investor from time to time) and to obtain acceleration of the effective date of
the Registration Statement.

         4.2     Demand Registration Rights.

                 (a)      If at any time during the period beginning on the
date of the Closing and ending on the third anniversary of the Closing, DMX
receives a written request therefor from the Investor, DMX shall prepare and
file a Registration Statement under the 1933 Act covering the Registrable
Shares which are the subject of such request and shall use its best efforts to
cause such Registration Statement to become effective, provided, however, that
DMX shall not be required to effect a registration under this Section 4.2
within six months of any prior registration in which Registrable Shares could
have been included under Section 4.1 hereof and in which all such Registrable
Shares requested for inclusion, if any, were included.

                 (b)      DMX shall be obligated to prepare, file and cause to
become effective no more than three Registration Statements pursuant to this
Section 4.2. DMX shall not be required by this Section 4.2 to effect a
registration of Registrable Shares pursuant to any Registration Statement
unless 500,000 (or all, if less than 500,000) Registrable Shares then held by
the Investor are covered thereby.

                 (c)      If a registration requested pursuant to this Section
4.2 is an underwritten registration in which the obligation of the underwriters
is to take all of the Registrable Shares to be sold if any are to be taken. DMX
and other security holders of DMX may include securities in such registration
without the consent of the Investor unless the managing underwriters of such
registration advise DMX in writing that in their opinion such inclusion would
adversely affect the successful marketing of the Registrable Shares to be
included in such registration.

                 (d)      DMX shall be entitled to postpone for a reasonable
period of time (but not exceeding 90 days) (the "Postponement Period") the
filing of any Registration Statement otherwise required to be prepared and
filed by it pursuant to this Section 4.2 if DMX determines, in its reasonable
judgment, that such registration and offering would interfere with any
financing, acquisition, corporate reorganization or other material transaction
involving DMX or any of its affiliates or would require premature disclosure
thereof and promptly gives the Investor written notice of such determination,
which notice shall contain a general statement of the reasons for such
postponement and an approximation of the anticipated delay. If DMX shall so
postpone the filing of a Registration Statement, the Investor shall have the
right to withdraw the request for registration by giving written notice to DMX
within 30 days after receipt of the notice of postponement and, in the event of
such withdrawal, such request shall not be counted for purposes of the requests
for registration to which the Investor is entitled pursuant to this Section
4.2.

                 The Investor may, before such Registration Statement becomes
effective, withdraw its Registrable Shares from sale, provided that such
Registration Statement shall be counted for purposes of Section 4.2(b) hereof
unless the Investor agrees to pay the out-of-pocket expenses of DMX incurred in
respect of such registration.

         4.3     Additional Registration Procedures. If, at any time and 
from time to time, DMX is required to effect the registration of 
Registrable Shares for the Investor under the 1933 Act, then DMX shall:

                 (a)      Before filing a Registration Statement or prospectus
or any amendments or supplements thereto, furnish to the Investor and its
counsel draft copies of all such documents proposed to be filed or used
(including, at the request of the Investor, all documents incorporated therein
by reference and all exhibits, including those incorporated by reference), a
reasonable amount of time prior to such proposed filing or use, which documents
will be subject to the reasonable review of the Investor, and DMX will
undertake to remove from the Registration Statement all Registrable Shares
included therein at the request of the Investor if the Investor shall
reasonably object to any such filing;

                 (b)      Notify the Investor, promptly after it shall receive
notice thereof, of the time when such Registration Statement has become
effective with the SEC or an amendment to such Registration Statement or a
supplement to any prospectus forming a part of such Registration Statement has
been filed;

                 (c)      Notify the Investor promptly of any request by the
SEC, or any other federal or state governmental authority, for the amending or
supplementing of such Registration Statement or prospectus or for additional
information;

                 (d)      For a period of at least 90 days from the effective
date of the Registration Statement, prepare and file with the SEC such
amendments and supplements to such Registration Statement and prospectus used
in connection therewith as may be necessary to keep such Registration Statement
effective and to comply with the provisions of the 1933 Act with respect to the
offer of the Registrable Shares covered by such Registration Statement;

                 (e)      Furnish to the Investor such number of copies of the
prospectus (including any preliminary prospectus or supplemental or amended
prospectus) as the Investor may reasonably request in order to facilitate the
sale and distribution of the Registrable Shares in accordance with the 1933 Act
and the intended methods of disposition set forth in such prospectus or
supplement;

                 (f)      Notify the Investor in writing, in the event DMX
believes the last prospectus filed pursuant to Rule 424 under the 1933 Act in
connection with the Registration Statement may contain misleading statements or
material omissions, in which case the Investor agrees to cease utilizing such
prospectus for the sale of Registrable Shares and DMX agrees, as soon
thereafter as practicable, to prepare and file with the SEC such amendment or
supplement to such prospectus as may be necessary to meet the requirements of
the 1933 Act;

                 (g)      Advise the Investor, promptly after it receives
notice or obtains knowledge thereof, of the issuance of any stop order by the
SEC suspending the effectiveness of such

Registration Statement or of the issuance by any state securities commission or
other regulatory authority of any order suspending the qualification or
exemption from qualification of any of the Registrable Shares under state
securities or Blue Sky laws or the initiation or threatening of any proceeding
for that purpose and promptly use its best efforts to prevent the issuance of
any such order by the SEC or to obtain its withdrawal at the earliest possible
moment if such order should be issued;

                 (h)      Make available for inspection by any underwriter in
any disposition pursuant to such Registration Statement, and any attorney,
accountant or other agent retained by any underwriter or the Investor, all
financial and other records reasonably necessary for such persons to
demonstrate that they have conducted a "reasonable investigation" of the
matters described in the Registration Statement, as that term is described in
Section 11 of the 1933 Act, and cause DMX's officers, directors, employees and
independent accountants to supply all information reasonably requested by the
Investor or any such underwriter, attorney, accountant or agent in connection
therewith;

                 (i)      Use its best efforts to register or qualify the
Registrable Shares covered by each Registration Statement under such securities
or Blue Sky laws of such jurisdictions as the Investor and the managing
underwriters may reasonably request; provided that DMX shall not be required to
execute any general consent to service of process or to qualify as a foreign
corporation or as a dealer in securities in any jurisdiction where it is not so
qualified;

                 (j)      If the offering is to be underwritten, enter into
such agreements (including an underwriting agreement in such form, scope and
substance as is customary in underwritten offerings, provided that the
indemnification provisions of any underwriting agreement shall be substantially
as set forth in Section 4.7 hereof) and take all such other actions in
connection therewith in order to expedite or facilitate the disposition of such
Registrable Shares and, in such connection: (i) make customary representations
and warranties to the Investor and the underwriters covering the matters
customarily covered in opinions in underwritten offerings; (ii) obtain opinions
of counsel to DMX and updates thereof (which counsel and opinions (in form,
scope and substance) shall be reasonably satisfactory to the underwriters and
the Investor and its counsel) addressed to the Investor and the underwriters
covering the matters customarily covered in opinions in underwritten offerings;
(iii) obtain customary "cold comfort" letters and updates thereof from the
independent certified public accountants addressed to the Investor and the
underwriters covering matters of the type customarily covered in "cold comfort"
letters in underwritten offerings; and (iv) deliver such other customary
documents and certificates as may be requested by the Investor or its counsel
and the underwriters;

                 (k)      Comply with all applicable rules and regulations of
the SEC relating to the Registration Statement;

                 (l)      Use its reasonable efforts to take all other steps
necessary to effect the registration of the Registrable Shares contemplated
hereby;

<PAGE>   11
                 (m)      If any of the Registrable Shares are to be sold in an
underwritten public offering pursuant to this Agreement, DMX shall promptly
notify the Investor as to its selection of the managing underwriters for the
offering; and

                 (n)      Cause such Registrable Shares to be listed on the
principal exchange or exchanges on which DMX's common stock is then listed or
to be included in NASDAQ if such common stock is then a NASDAQ security.

                 4.4      Reporting Requirements Under the Securities Exchange
Act of 1934. DMX shall timely file such information, documents, and reports as
the SEC may require or prescribe under either Section 13 or 15(d) (whichever is
applicable) of the Exchange Act. DMX shall, whenever requested by the Investor,
notify the Investor in writing whether DMX has, as of the date specified by the
Investor, complied with the Exchange Act reporting requirements to which it is
subject for a period prior to such date as shall be specified by the Investor.
DMX acknowledges and agrees that the purposes of the requirements contained in
this Section 4.4 are: (a) to enable the Investor to comply with the current
public information requirement contained in Paragraph (c) of Rule 144 under the
1933 Act should the Investor ever wish to dispose of any of the Shares acquired
by it without registration under the 1933 Act in reliance upon Rule 144 (or any
equivalent successor provision or similar rule hereafter adopted); and (b) to
qualify DMX for the use of registration statements on Form S-3, or its
equivalent successor form, in connection with secondary distributions of
securities of DMX. DMX shall use its best efforts to qualify for the use of Form
S-3, or its equivalent successor form, with respect to secondary distributions.
In addition, DMX shall take such other measures and file such other information,
documents, and reports as shall hereafter be required by the SEC as a condition
to the availability of Rule 144 under the 1933 Act (or any equivalent successor
provision or similar rule hereafter adopted), including, without limitation,
using its best efforts to assure that there shall be available at all times
adequate public information with respect to DMX and the Common Stock. The
obligation to make available adequate public information and otherwise take such
measures necessary to maintain the availability of Rule 144 shall continue in
the event that DMX shall cease to become subject to the filing requirements of
Section 13 or Section 15(d) of the Exchange Act.

                 4.5      Expenses. All expenses incident to DMX's performance
of or compliance with its undertaking in this Article IV, including, without
limitation, all registration and filing fees (other than registration and
filing fees in excess of $5,000 imposed by state securities or Blue Sky laws),
printing expenses, messenger and delivery expenses, and fees and disbursements
of counsel for DMX and all independent certified public accountants,
underwriters (excluding discounts and commissions and transfer taxes) and other
persons retained by DMX (all such expenses being herein called "Registration
Expenses"), will be borne by DMX, whether or not such Registration Statement
becomes effective. DMX will, in all events, pay its internal expenses
(including, without limitation, all salaries and expenses of its officers and
employees performing legal or accounting duties), the expense of any annual
audit and the expense of any liability insurance.

         4.6     Investor's Obligations.

                 (a)      The Investor agrees upon the filing of a Registration
Statement covering the Registrable Shares, if requested by the managing
underwriters in an underwritten offering, not to effect any public sale or
distribution of securities of DMX of the same class as the securities included
in such Registration Statement, during the 10-day period prior to, and during
the five-day period beginning on, the closing date of each underwritten offering
made pursuant to such Registration Statement, to the extent timely notified in
writing by DMX or the managing underwriters.

                 (b)      Whenever registration of any Registrable Shares is
being effected, DMX may require the Investor to furnish to DMX such information
regarding the distribution of such securities and such other information to be
included in such Registration Statement as DMX may from time to time reasonably
request in writing.

         4.7     Indemnification, Contribution.

                 (a)      In the event of any registration of any Registrable
Shares under the 1933 Act pursuant to this Agreement, DMX shall indemnify and
hold harmless, to the full extent permitted by law and without limitation as to
time, the Investor, each of its directors, officers, employees and agents and
each person, if any, who controls the Investor (within the meaning of the 1933
Act or the Exchange Act), and the respective directors, officers, employees and
agents of any such controlling person, any underwriter for the Investor and
each affiliate of the Investor or any such underwriter within the meaning of
the 1933 Act (collectively, the "Indemnified Persons"), against any losses,
claims, damages or liabilities, joint or several, to which any Indemnified
Person may become subject, under the 1933 Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of, or are based upon, any untrue statement or alleged untrue statement of any
material fact contained in or incorporated by reference into such Registration
Statement or preliminary prospectus (if used prior to the effective date of
such Registration Statement) or final or summary prospectus contained therein
(if used during the period DMX is required to keep the Registration Statement
effective), or any amendment or supplement thereto, or arise out of, or are
based upon, the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements made therein
(in the case of a prospectus or form of prospectus or supplement thereto, in
light of the circumstances under which they are made) not misleading, and will
reimburse each Indemnified Person for any legal or any other expenses
reasonably incurred by it in connection with investigating or defending any
such action or claim (excluding any amounts paid in settlement of any
litigation, commenced or threatened, if such settlement is effected without the
prior written consent of DMX, which consent shall not be unreasonably
withheld); provided, however, that DMX will not be liable to a particular
Indemnified Person in any such case (i) to the extent that any such loss,
claim, damage, liability or expense arises out of, or is based upon, an untrue
statement or omission or alleged untrue statement or alleged omission made in
said Registration Statement, said preliminary prospectus or said final or
summary prospectus or any amendment or supplement thereto, in reliance upon and
in conformity with written


                                      -12-
<PAGE>   13
information furnished to DMX by that Indemnified Person or by the Investor
specifically for use in the preparation thereof, (ii) DMX has advised the
Investor of the occurrence of an event described in Section 4.3(f) and the
Investor has sold Registrable Shares notwithstanding such notice prior to
receipt of a supplement or amended prospectus or (iii) to the extent any such
loss, claim, damage, liability or expense are caused by the Investor's failure,
where required, to deliver a copy of the Registration Statement or prospectus;
and provided further that the indemnity agreement contained in this Section
4.7(a) with respect to any preliminary prospectus shall not inure to the
benefit of any Indemnified Person in respect of any loss, claim, damage,
liability or action asserted by someone who purchased Registrable Shares from
such person if (i) a copy of the final prospectus (as the same may be amended
or supplemented) in connection with such Registration Statement was not sent or
given to such person with or prior to written confirmation of the sale, (ii)
such final prospectus shall correct the untrue statement or alleged untrue
statement, or omission or alleged omission, which is the basis of such loss,
claim, liability or action, and (iii) there would have been no such liability
but for the failure to deliver such final prospectus by the Investor.

                 (b)      In the event of any registration of Registrable
Shares under the 1933 Act pursuant to this Agreement, the Investor shall
indemnify and hold harmless, to the full extent permitted by law and without
limitation as to time, DMX, each of its directors, officers, employees and
agents and each person, if any, who controls DMX (within the meaning of the
1933 Act or the Exchange Act), and the respective directors, officers,
employees and agents of any such controlling person, any underwriter and each
affiliate of DMX or any such underwriter within the meaning of the 1933 Act
(collectively, the "Indemnified Persons"), against any losses, claims, damages
or liabilities, joint or several, to which DMX or any Indemnified Person may
become subject, under the 1933 Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of, or
are based upon, any untrue statement or alleged untrue statement of any
material fact contained in or incorporated by reference into such Registration
Statement or preliminary prospectus or final or summary prospectus contained
therein, or any amendment or supplement thereto, or arise out of or are based
upon the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements made therein (in the
case of a prospectus or form of prospectus or supplement thereto, in light of
the circumstances under which they are made) not misleading, and will reimburse
such Indemnified Person for any legal or other expenses reasonably incurred by
it in connection with investigating or defending any such action or claim
(excluding any amounts paid in settlement of any litigation, commenced or
threatened, if such settlement is effected without the prior written consent of
the Investor, which consent shall not be unreasonably withheld); but in all
such cases only if, and to the extent that, any such loss, claim, damage,
liability or expense arises out of or is based upon an untrue statement or
alleged untrue statement or omission or alleged omission therein made in
reliance upon and in conformity with written information furnished to DMX by
the Investor specifically for use in the preparation thereof. DMX shall be
entitled to receive indemnities from underwriters, selling brokers, dealer
managers and similar securities industry professionals participating in the
distribution, to the same extent as provided above with respect to information
so furnished in writing by such persons specifically for inclusion in any
prospectus or Registration Statement.

<PAGE>   14
                 (c)      Promptly after receipt by a party entitled to
indemnification under Section 4.7(a) or 4.7(b) hereof of notice of the
commencement of any action, such indemnified party will, if a claim in respect
thereof is to be made against the indemnifying party under either of such 
Sections, notify the indemnifying party in writing of the commencement thereof.
In case any such action is brought against the indemnified party and it shall so
notify the indemnifying party of the commencement thereof, the indemnifying
party shall be entitled to participate in, and, to the extent that it so chooses
and acknowledges its obligation to indemnify the indemnified party for any loss,
claim, liability or expense suffered by the indemnified party, if any, in
connection with the action, to assume the defense thereof with counsel
reasonably satisfactory to such indemnified party and, after notice from the
indemnifing party that it so chooses to assume the defense of the action, such
indemnifying party shall not be liable for any legal or other expenses
subsequently incurred by such indemnified party in connection with the defense
thereof, unless the named parties to any such action, claim or proceeding
(including any impleaded parties) include both such indemnified party and the
indemnifying party, and such indemnified party shall have been advised by
counsel that there may be one or more legal defenses available to it which are
different from or additional to those available to the indemnifying party (in
which case, if such indemnified party notifies the indemnifying party in writing
that it elects to employ separate counsel at the expense of the indemnifying
party, the indemnifying party shall not have the right to assume the defense of
such action, claim 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, claim or proceeding or separate but substantially similar
or related actions, claims or proceedings in the same jurisdiction 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 (together with
appropriate local counsel) at any time for all such indemnified parties, unless
in the reasonable judgment of such indemnified party a conflict of interest may
exist between such indemnified party and any other indemnified parties with
respect to such action, claim or proceeding, in which event the indemnifying
party shall be obligated to pay the fees and expenses of such additional counsel
or counsels); provided, however, that if the indemnifying party fails to take
reasonable steps necessary to diligently defend such claim within 20 days after
receiving notice from the indemnified party that the indemnified party believes
the indemnifying party has failed to take such steps, the indemnified party may
assume its own defense and the indemnifying party shall be liable for any
expenses therefor. The indemnity agreements in this Section 4.7 shall be in
addition to any liabilities which the indemnifying parties may have pursuant to
law.

                 (d)      If the indemnification provided for in this Section
4.7 from the indemnifying party is unavailable to an indemnified party
hereunder in respect of any losses, claims, damages, liabilities or expenses
referred to herein, then the indemnifying party, in lieu of indemnifying such
indemnified party, shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages, liabilities or
expenses in such proportion as is appropriate to reflect the relative fault of
the indemnifying party and indemnified parties in connection with the actions
or inactions which resulted in such losses, claims, damages, liabilities or
expenses, as well as any other relevant equitable considerations. The relative
fault of such indemnifying party and indemnified parties shall be determined by
reference to, among other things, whether any action in question, including any
untrue or alleged untrue statement of a material fact, has been made by, or


                                      -14-
<PAGE>   15
related to information supplied by, such indemnifying party or indemnified
parties, and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such action. The amount paid or payable
by a party as a result of the losses, claims, damages, liabilities and expenses
referred to above shall be deemed to include, subject to the limitations set
forth in Section 4.7(c), any legal or other fees or expenses reasonably
incurred by such party in connection with any investigation or proceeding.

                 The parties hereto agree that it would not be just and
equitable if contribution pursuant to this Section 4.7(d) were determined by
pro rata allocations or by any other method of allocation which does not take
account of the equitable considerations referred to in the immediately
preceding paragraph. 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.

                 (e)      The indemnification and contribution provided for in
this Section 4.7 shall remain in full force and effect regardless of any
investigation made by or on behalf of the indemnified party and will survive
the transfer of Registrable Shares. If indemnification is available under this
Section 4.7, the indemnifying parties shall indemnify each indemnified party to
the full extent provided in Sections 4.7(a) and (b) without regard to the 
relative fault of said indemnifying party or indemnified party or any other 
equitable consideration provided for in Section 4.7(d).

                                   ARTICLE V
                            MISCELLANEOUS PROVISIONS

                 5.1      Waiver. This Agreement shall not be altered or
amended except by a written instrument executed by DMX and the Investor. Any
waiver of any term, covenant, agreement or condition contained in this
Agreement shall not be deemed a waiver of any other term, covenant, agreement
or condition, and any waiver of any default in such term, covenant, agreement or
condition shall not be deemed a waiver of any later default thereof or of any
default of any other term, covenant, agreement or condition.

                 5.2      Severability. In the event that any one or more of
the provisions of this Agreement shall be invalid, illegal or unenforceable,
all other provisions hereof shall be given effect separately therefrom and
shall not be affected thereby.

                 5.3      Expenses. Except as otherwise provided herein, the
parties hereto shall be responsible for their own fees and expenses incurred in
connection with this Agreement.

                 5.4      Press Releases. All press releases or other public
communications relating to this Agreement or the transactions contemplated
hereby will require the prior approval of the Investor and DMX, unless counsel
has advised either party that such release or other public communication must
immediately be issued and the issuing party has not been able, despite its good
faith efforts, to secure the prior approval of the other party.

                          AGREEMENT AND PLAN OF MERGER

         This Agreement and Plan of Merger (this "Agreement"), dated as of
August 28, 1995, is made by and among United Artists Programming International,
Inc., a Delaware corporation ("UAPI"), TCI-Euromusic, Inc., a Colorado
corporation ("TCI-E"), and DMX Inc., a Delaware corporation ("Acquiror").

                             PRELIMINARY STATEMENTS

         UAPI is the owner of all the issued and outstanding capital stock of
TCI-E. TCI-E is the holder of two promissory notes (individually a "Note" and
together the "Notes") dated May 19, 1993, one in the principal amount of
$24,436,000 payable by International Cablecasting Technologies Europe N.V.
d/b/a DMX Europe N.V. ("DMX-E"), and the other in the principal amount of
$564,000 payable by DMX. TCI-E also owns 19,216 shares of capital stock of
DMX-E (the "DMX-E Stock").

         The Boards of Directors of TCI-E and Acquiror have each determined
that it is in the best interests of their respective corporations and
shareholders that TCI-E merge with and into Acquiror (the "Merger"), as a
result of which UAPI, as the sole shareholder of TCI-E immediately prior to the
Merger, would become a stockholder of Acquiror.

         The parties intend that, for federal income tax purposes, the Merger
will qualify as a tax-free reorganization within the meaning of Section
368(a)(1)(A) of the Code, and this Agreement is adopted as a plan of
reorganization.

the Delaware Corporation Law.

                                   ARTICLE II
                                   THE MERGER

         2.1     Closing and Closing Date. As soon as practicable after the
satisfaction or, to the extent permitted by law, waiver of the conditions set
forth in Article VII, (but not later than three Business Days after the
satisfaction or waiver of the conditions set forth in Section 7.1 (other than
the condition in Section 7.1 (c)), Section 7.2(e) and Section 7.3(d)), and
immediately prior to the filing of the Articles of Merger and the Certificate
of Merger, a closing of the transactions contemplated by this Agreement (the
"Closing") will take place at the offices of Manatt, Phelps & Phillips, 11355
West Olympic Boulevard, Los Angeles, California or such other location as the
parties may agree. The date on which the Closing occurs is referred to in this
Agreement as the "Closing Date."

         2.2     The Merger. Subject to the terms and conditions of this
Agreement, the Colorado Corporation Law and the Delaware Corporation Law, at
the Effective Time TCI-E will be merged with and into Acquiror, the separate
existence of TCI-E will cease and Acquiror will continue as the corporation
surviving the Merger (the "Surviving Corporation"). From and after the
Effective Time, and without any further action on the part of any Person, the
Merger will have all the effects provided by applicable law, including Section
7-111-106 of the Colorado Corporation Law and Section 259 of the Delaware
Corporation Law, the effects described in Section 3.1 with respect to the
capital stock of TCI-E and, subject to applicable law, the following additional
effects:

                 (a)      Certificate of Incorporation. At the Effective Time,
the Certificate of Incorporation of Acquiror will continue to be the
Certificate of Incorporation of the Surviving Corporation, and such Certificate
of Incorporation may thereafter be amended as provided therein and by the
Delaware Corporation Law.

                 (b)      Bylaws. At the Effective Time, the Bylaws of
Acquiror, as in effect immediately prior to the Effective Time, will continue
to be the Bylaws of the Surviving Corporation, and such Bylaws may thereafter
be amended or repealed in accordance with their terms and the Certificate of
Incorporation of the Surviving Corporation and as provided by the Delaware
Corporation Law.

<PAGE>   9
                 (c)      Directors. At the Effective Time, the directors of
Acquiror immediately prior to the Effective Time, together with the two
directors appointed pursuant to Section 6.9, will be the directors of the
Surviving Corporation, each to hold office in accordance with the Certificate
of Incorporation and Bylaws of the Surviving Corporation and the Delaware
Corporation Law and until the earlier of such director's resignation or removal
or until such director's successor is duly elected and qualified, as the case
may be.

                 (d)      Officers. At the Effective Time, the officers of
Acquiror immediately prior to the Effective Time will continue as the officers
of the Surviving Corporation, each to hold office in accordance with the
Certificate of Incorporation and Bylaws of the Surviving Corporation and the
Delaware Corporation Law and until the earlier of such officer's resignation or
removal or until such officer's successor is duly appointed and qualified, as
the case may be.

         2.3     Effective Time of the Merger. Subject to the terms and
conditions in this Agreement, the parties will (a) prepare, sign and
acknowledge, in accordance with the Colorado Corporation Law, articles of
merger (the "Articles of Merger") and deliver the Articles of Merger to the
Secretary of State of the State of Colorado for filing pursuant to the Colorado
Corporation Law on the Closing Date and (b) prepare, execute and acknowledge,
in accordance with the Delaware Corporation Law, a certificate of merger (the
"Certificate of Merger") and deliver the Certificate of Merger to the Secretary
of State of the State of Delaware for filing pursuant to the Delaware
Corporation Law on the Closing Date.  The Merger will become effective upon the
later of the filing of the Articles of Merger with the Secretary of State of
the State of Colorado and the filing of the Certificate of Merger with the
Secretary of State of the State of Delaware.  As used in this Agreement, the
"Effective Time" means the later of the time at which the Articles of Merger
are filed with the Secretary of State of the State of Colorado and the time at
which the Certificate of Merger is filed with the Secretary of State of the
State of Delaware.

                                  ARTICLE III
                          CONVERSION OF CAPITAL STOCK

         3.1     Conversion of Stock. At the Effective Time, by virtue of the
Merger and without any action on the part of the holder of any shares of
capital stock of any corporation:

                 (a)      Each share of common stock, $1.00 par value per
share, of TCI-E ("TCI-E Common Stock") issued and outstanding immediately prior
to the Effective Time will be converted into and will thereafter evidence and
become that number of validly issued, fully paid and nonassessable shares of
Acquiror Common Stock equal to the Conversion Number. If any holder of TCI-E
Common Stock is entitled to receive a fraction of a share of Acquiror Common
Stock, the number of shares of Acquiror Common Stock issuable to such holder
will be rounded to the nearest whole number.

                 (b)      Each share of the capital stock of Acquiror issued
and outstanding immediately prior to the Effective Time will remain issued and
outstanding.





                                      -5-
<PAGE>   10
         3.2     Conversion Number. For purposes of this Agreement:

                 (a)      The "Conversion Number" will be equal to the quotient
(rounded to the nearest one-thousandth) of the TCI-E Common Stock Value divided
by the Acquiror Common Stock Value (rounded to the nearest one-thousandth).

                 (b)      The "TCI-E Common Stock Value" will equal the
quotient of the TCI-E Value divided by the number of shares of TCI-E Common
Stock issued and outstanding immediately prior to the Effective Time.

                 (c)      The "Acquiror Common Stock Value" will be $2.50,
subject to adjustment as provided below:

                          (i) If before the Effective Time there occurs the
ex-dividend date or record date with respect to (A) a dividend or other
distribution on outstanding shares of any class of capital stock of Acquiror in
the form of shares of Acquiror Common Stock, (B) a subdivision of the then
outstanding shares of Acquiror Common Stock into a greater number of shares of
Acquiror Common Stock or (C) a combination of the then outstanding shares of
Acquiror Common Stock into a smaller number of shares of Acquiror Common Stock,
then the Acquiror Common Stock Value then in effect will be adjusted by
multiplying it by a fraction, the numerator of which is the number of shares of
Acquiror Common Stock outstanding immediately before the event giving rise to
such adjustment and the denominator of which is the number of shares of
Acquiror Common Stock outstanding immediately after such event.

                          (ii)    If before the Effective Time there occurs the
ex-dividend date or record date with respect to a dividend or other
distribution on outstanding shares of Acquiror Common Stock in the form of
cash, securities or other assets (other than any cash dividend payable out of
earnings or any dividend or distribution in the form of Acquiror Common Stock),
then the Acquiror Common Stock Value then in effect will be adjusted by
multiplying it by a fraction, the numerator of which is the Average Trading
Price of Acquiror Common Stock on the record date (or if earlier, the
ex-dividend date) of such dividend or distribution less the amount of cash or
the fair market value on such date (as reasonably determined by Acquiror's
Board of Directors) of the portion of the securities or other assets so to be
distributed that is applicable to one share of Acquiror Common Stock, and the
denominator of which is the Average Trading Price of Acquiror Common Stock on
such date.

                          (iii)   If any event involving dividends or
distributions with respect to, or any change in the number of, outstanding
shares of capital stock of Acquiror occurs as to which the other provisions of
this Section 3.2(c) are not strictly applicable but the failure to make an
adjustment in the Acquiror Common Stock Value would be inconsistent with the
general intent and principles reflected in such provisions, or if strictly
applicable would be inconsistent with the general intent and principles
reflected in such provisions, then Acquiror, by action of its Board of
Directors,





                                      -6-
<PAGE>   11
will make an adjustment, on a basis that Acquiror's Board of Directors
determines reasonably and in good faith is consistent with such general intent
and principles. Acquiror will respond reasonably and in good faith to any
request by UAPI that Acquiror's Board of Directors make a determination
pursuant to this Section 3.2(c). Acquiror may, at its election, request that
UAPI approve such an adjustment, and if UAPI grants such approval, Acquiror
will be deemed to have acted reasonably and in good faith in making that
adjustment. The failure of Acquiror to request such approval or of UAPI to
approve such a request will not be construed as in any way affecting the rights
of any of the parties.

                 (d)      "Average Trading Price" of Acquiror Common Stock will
equal, as of a particular date, the average of the reported closing market
prices of such stock for the 10 consecutive trading days ending on the day
prior to the date of determination. The closing market price for each day in
question will be the last sale price, regular way or, if no such sale takes'
place on such day, the average of the closing bid and asked prices, regular
way, in either case as reported in the principal consolidated transaction
reporting system of the principal national securities exchange on which such
stock is listed or admitted to trading or, if such stock is not listed or
admitted to trading on any national securities exchange, the last quoted sale
price or, if no such sale price is quoted, the average of the high bid and low
asked prices in the over-the-counter market, as reported by the Nasdaq National
Market System ("Nasdaq") or such other system then in use or, if on any such
trading day such capital stock is not quoted by any such organization, the
average of the closing bid and asked prices as furnished by the professional
market maker who has been most active in making a market in such capital stock
during the preceding 12 months. The Average Trading Price of such stock will be
appropriately adjusted to reflect the effects of any stock dividend, stock
split, reclassification, recapitalization or combination affecting such stock,
the record date or ex-dividend date of which occurs during the period in which
the Average Trading Price is to be determined.

                 (e)      The "TCI-E Value" means the sum, calculated as of the
Effective Time. of (i) $120,100 plus (ii) the unpaid principal balance of the
Notes plus (iii) all accrued and unpaid interest on the Notes as of August 28,
1995, minus (iv) the amount, not to exceed $ 1,600,000, by which the aggregate
amount payable by DMX-E to Acquiror exceeds the aggregate amount payable by
Acquiror to DMX-E (the "DMX-E Payable"). The calculation of amounts payable by
DMX-E to Acquiror will be made in accordance with the Technology License and
Services Agreement dated May 19, 1993, between Acquiror and DMX-E.

         3.3     Procedures for Determining TCI-E Value.

                 (a)      At least five Business Days before the Closing Date,
(i) TCI-E will deliver to Acquiror a schedule setting forth the amount of each
item required to calculate the TCI-E Value as of the Closing Date pursuant to
Section 3.2(e) other than the DMX-E Payable and (ii) Acquiror will deliver to
TCI-E Acquiror's calculation of the DMX-E Payable as of the Closing Date. TCI-E
and Acquiror will make available to each other before the Closing all
information that the other reasonably requests in support of the calculations
provided pursuant to the preceding sentence.





                                      -7-
<PAGE>   12
                 (b)      If neither Acquiror nor TCI-E provides a written
notice of disagreement with the other's calculation at least two Business Days
before the Closing Date, the calculation of the TCIE Value and the Conversion
Number based on the amounts so provided will be final, conclusive and
nonappealable.

                 (c)      If either Acquiror or TCI-E provides a written notice
of disagreement with the other's calculations within the period specified in
Section 3.3(b), the calculation of the TCI-E Value using the amounts provided
pursuant to Section 3.3(a) (the "Disputed TCI-E Value") will be used to
calculate the Conversion Number and the failure of the parties to agree on such
calculations will not be cause for postponement of the Closing. Acquiror and
UAPI will negotiate in good faith to resolve any such dispute for a period of
30 days after the Closing. At the end of such period, if the dispute has not
been resolved or the negotiation period has not been extended by agreement
between UAPI and Acquiror, the dispute will be referred to an independent
public accounting firm selected by agreement of UAPI and Acquiror (or, if UAPI
and Acquiror cannot agree to the selection of such a firm within five days
after the end of such 30-day period, an independent public accounting firm
selected by KPMG Peat Marwick), which firm will render its decision as to
whether Acquiror's position is correct, UAPI's position is correct or some
position between the two is correct (together with an explanation of the basis
therefor) to the parties to the dispute not later than 30 days following
submission of the dispute to it, which decision will be final, conclusive and
nonappealable. The fees and expenses of such accounting firm will be paid
one-half by Acquiror and one-half by UAPI.

                 (d)      If the TCI-E Value as finally determined is less than
the Disputed TCI-E Value, UAPI will deliver to Acquiror for cancellation
certificates representing the shares of Acquiror Class B Common Stock in excess
of those required to be issued, together with all nontaxable distributions, if
any, made with respect to such shares after the date of their issuance. Any
cash dividends or other taxable distributions payable with respect to such
shares during the period of time that the shares were outstanding will be
retained by the holder of such shares notwithstanding the cancellation of such
shares. If the TCI-E Value as finally determined is greater than the Disputed
TCI-E Value, Acquiror will deliver to the Person entitled to such shares
certificates representing the appropriate number of shares of Acquiror Common
Stock, together with any dividends or distributions to which such Person would
have been entitled had such shares been issued at the Closing.

         3.4     Exchange of Certificates. At the Closing, (a) UAPI will
deliver to Acquiror certificates representing all the issued and outstanding
shares of TCI-E Common Stock and Acquiror will deliver to UAPI (or such other
Person as UAPI may designate in writing) certificates representing the number
of shares of Acquiror Common Stock to be issued in the Merger pursuant to this
Agreement (subject, in case there is a Disputed TCI-E Value, to final
determination pursuant to Section 3.3), which shares of Acquiror Common Stock
will be deemed to be issued at the Effective Time and (b) UAPI will deliver or
cause to be delivered to Acquiror the Notes and certificates representing the
DMX-E Stock held by TCI-E.

                                   ARTICLE IV
                REPRESENTATIONS AND WARRANTIES OF TCI-E AND UAPI

         TCI-E and UAPI jointly and severally represent and warrant to Acquiror

         4.1     Organization and Authority; Binding Effect. Each of TCI-E and
UAPI is a corporation duly organized, validly existing and in good standing
under the laws of its state of incorporation and has all requisite corporate
power and authority to execute and deliver, to perform its obligations under,
and to consummate the transactions contemplated by, this Agreement. TCI-E has
all requisite corporate power and authority to own, lease and operate its
properties and to carry on its business as now being conducted and is duly
qualified to do business in each jurisdiction in which the properties owned,
leased or operated by it or the nature of the business conducted by it makes
such qualification necessary, except where the failure so to be qualified would
not have a material adverse effect on the financial condition, results of
operations, liabilities, assets or business of TCI-E. All necessary corporate
action required to be taken by or on behalf of TCI-E and UAPI by applicable
law, the Certificate or Articles of Incorporation and Bylaws of TCI-E and UAPI
or otherwise to authorize (a) the approval, execution and delivery on behalf of
TCI-E and UAPI of this Agreement and (b) the performance by each of TCI-E and
UAPI of its obligations under this Agreement and the consummation of the
transactions contemplated by this Agreement has been taken. Assuming that this
Agreement constitutes a valid, binding and enforceable agreement of Acquiror,
this Agreement constitutes a valid and binding agreement of each of TCI-E and
UAPI, enforceable against each of them in accordance with its terms, except (x)
as enforcement of this Agreement may be limited by applicable bankruptcy,
insolvency, moratorium, or similar laws of general application relating to or
affecting creditors' rights, including the effect of statutory or other laws
regarding fraudulent conveyances and preferential transfers and (y) for
limitations imposed by general principles of equity. TCI-E has delivered to
Acquiror true and complete copies of its Articles of Incorporation and Bylaws.

         4.2     No Breach. The execution and delivery of this Agreement by
TCI-E and UAPI do not, and the consummation of the transactions contemplated by
this Agreement by TCI-E and UAPI will not, (a) violate or conflict with the
Articles or Certificate of Incorporation or Bylaws of TCI-E or UAPI or (b) in
any material respect, constitute a breach or default (or an event that with
notice or lapse of time or both would become a breach or default) or give rise
to any lien or any third-party right of termination, cancellation, modification
or acceleration under any instrument or agreement to which TCI-E or UAPI is a
party or by which either of them or assets of either of them is bound or (c)
subject to obtaining the approvals and making the filings described in Section
4.3, in any material respect, violate any statute, law, ordinance, rule or
regulation applicable to TCI-E, UAPI or assets of either of them.

         4.3     Governmental Consents and Approvals. Neither the execution and
delivery of this Agreement by TCI-E and UAPI nor the consummation of the
transactions contemplated by this Agreement will require any consent, approval,
authorization or permit of, or any filing with or notification to, any
Governmental Authority, except for (a) filing of the Certificate of Merger, the





                                      -9-

waiting period under, the HSR Act.

outstanding 1,000 shares of TCI-E Common Stock. All issued and outstanding
shares of TCI-E Common Stock were validly issued, are fully paid and
nonassessable and are owned beneficially and of record by UAPI.  There are no
options, warrants, calls, subscriptions or other commitments obligating TCI-E
or UAPI to issue (or reserve for issue), transfer or sell any securities of
TCI-E. There is no voting trust or other agreement to which either TCI-E or
UAPI is a party with respect to the voting of capital stock of TCI-E.

         4.5     Assets and Liabilities of TCI-E.

                 (a)      Assets. TCI-E has no material assets other than (i)
its rights under this Agreement, (ii) the DMX-E Stock and (iii) its rights

                 (b)      Liabilities. Except for (i) its obligations under the
instruments and agreements evidencing the Note Rights, (ii) its obligations
under this Agreement and (iii) its obligations for amounts payable to one or

authority to own, lease and operate its properties and to carry on its business
as now being conducted and is duly qualified to do business in each
jurisdiction in which the properties owned, leased or operated by it or the

Acquiror of the transactions contemplated by, this Agreement will not, (a)

Acquiror, (b) in any material respect, constitute a breach or default (or an
event that with notice or lapse of time or both would become a breach or
default) or give rise to any lien or any third-party right of termination,
cancellation, modification or acceleration under any instrument or agreement to
which Acquiror is a party or by which Acquiror or any of its assets is bound or
(c) subject to obtaining the approvals and making the filings described in
Section 5.3, in any material respect, constitute a violation of any statute,

Directors of Acquiror has, by resolution duly adopted at a meeting duly called

Act with the SEC since June 30, 1995. The Annual Report describes, among other
things, the business, operations and principal properties of Acquiror in
accordance with the requirements of the applicable report form. As of the date
of their filing, the Acquiror SEC Filings did not contain any untrue statement
of a material fact or omit to state any material fact necessary in order to
make the statements therein not misleading.  Except as disclosed in the
Acquiror SEC Filings, since June 30, 1995, there have been no material changes
in the business, results of operations, financial condition or properties of
Acquiror required to be reported to the SEC pursuant to the Exchange Act.

portion of any of its properties or assets (real, personal or mixed, tangible
or intangible), except in the ordinary course of business and consistent with
past practice;

                 (f)      declared, paid or set aside for payment any dividend
or other distribution in respect to its capital stock or redeemed, purchased or

tangible or intangible) to, or entered into any agreement or arrangement with,
any of its officers or directors or any Affiliate of any of its officers or
directors except for directors' fees, compensation to officers at rates not
exceeding the rates of compensation reflected in the Acquiror SEC Filings and
the grant of options as disclosed in Schedule 5.4(a); or

                 (i)      entered into any transaction not in the ordinary
course of business;

                 (j)      except with respect to DMX-E, made any loans to,

except for loans, guarantees, obligations or equity investments in amounts
which are not material; or

                 (k)      agreed, whether in writing or otherwise, to take any
action described in this Section.

         5.8     Brokers and Finders. Neither Acquiror nor any of its officers,
directors, employees, or Affiliates has employed any broker or finder or

         6.1     Access to Information. Between the date of this Agreement and
the Effective Time, TCI-E and Acquiror each will (a) give the other party and
its authorized representatives reasonable access, during regular business hours
upon reasonable notice, to all offices and other facilities of such party and
its subsidiaries and to all books and records of such party and its
subsidiaries, (b) permit the other party to make such reasonable inspections of
the offices, facilities, books, and records described in clause (a) as it may
require and (c) cause its officers and those of its subsidiaries to furnish the
other party with such financial and operating data and other information with
respect to the business and properties of TCI-E or Acquiror and its
subsidiaries, as the case may be, as the other party may from time to time
reasonably request. All such access and information obtained by either TCI-E or
Acquiror and their respective authorized representatives will be subject to
Section 6.2.

         6.2     Confidentiality. No party will issue any press release or make
any other public announcement regarding this Agreement or the transactions
contemplated hereby without the consent of the other parties. Each party will
hold, and will cause its employees, consultants, advisors and agents to hold,
in confidence, the terms of this Agreement and any non-public information
concerning the other party obtained pursuant to this Agreement. Notwithstanding
the preceding, a party may disclose such information to the extent required by
law (including disclosure requirements under federal and state securities
laws), but the party proposing to disclose such information will first notify
and consult with the other party concerning the proposed disclosure, to the
extent reasonably feasible. Each party also may disclose such information to
employees, consultants, advisors, agents and actual or potential lenders or
equity investors whose knowledge is necessary to facilitate the consummation of
the transactions contemplated by this Agreement. Each party's obligation to
hold information in confidence will be satisfied if it exercises the same care
with respect to such information as it would exercise to preserve the
confidentiality of its own similar information.

         6.3     Reasonable Best Efforts. Each of the parties to this Agreement
will use its reasonable best efforts to take, or cause to be taken, all
appropriate action, and to do, or cause to be done, all things necessary,
proper or advisable under applicable law to consummate and make effective the
transactions contemplated by this Agreement in the most expeditious manner
practicable, including the satisfaction of all conditions to the Merger.

         6.4     Notification. Each party to this Agreement will, in the event
of, or promptly after obtaining knowledge of the occurrence or threatened
occurrence of, any fact or circumstance that would cause or constitute a breach
of any of its representations and warranties set forth herein, give notice
thereof to the other parties and will use its reasonable best efforts to
prevent or remedy such breach.

         6.5     Meeting of Stockholders of Acquiror. Acquiror will take all
action necessary, in accordance with the Delaware Corporation Law and its
Certificate of Incorporation and Bylaws, to





                                      -15-
<PAGE>   20
duly call, give notice of, convene and hold a meeting of its stockholders as
promptly as practicable, to consider and vote upon the adoption and approval of
this Agreement (as an agreement of merger under Section 252 of the Delaware
Corporation Law), the Merger and the other transactions contemplated by this
Agreement, to the extent such approval is required by the Delaware Corporation
Law, Acquiror's Certificate of Incorporation and Part III of Schedule D to the
By-Laws of the National Association of Securities Dealers, Inc. The stockholder
vote required for the adoption and approval of this Agreement, the Merger and
the other transactions contemplated by this Agreement will be the vote required
by the Delaware Corporation Law and Acquiror's Certificate of Incorporation.
Subject to the fiduciary duty of the Board of Directors of Acquiror under
applicable law, Acquiror will use its reasonable best efforts to secure the
vote of stockholders required by the Delaware Corporation Law and Acquiror's
Certificate of Incorporation to effect such transactions within 90 days after
the date of this Agreement.

         6.6     Regulatory and Other Authorizations.

                 (a)      Governmental Consents. TCI-E and Acquiror will use
their respective reasonable best efforts to obtain all authorizations,
consents, orders and approvals of federal, state, local and foreign regulatory
bodies and officials and non-governmental third parties that may be or become
necessary for its respective execution and delivery of, and the performance of
its respective obligations pursuant to, this Agreement, and will cooperate
fully with the other parties in promptly seeking to obtain all such
authorizations, consents, orders and approvals.

                 (b)      HSR Act Filings. As soon as practicable after the
execution of this Agreement, but in any event no later than 15 days after such
execution, UAPI and Acquiror each will complete and file, or cause to be
completed and filed, any notification and report required to be filed under the
HSR Act. Each of the parties will take any additional action that may be
necessary, proper or advisable, will cooperate to prevent inconsistencies
between their respective filings and will furnish to each other such necessary
information and reasonable assistance as the other may reasonably request in
connection with its preparation of necessary filings or submissions under the
HSR Act. Notwithstanding anything to the contrary in this Agreement, if UAPI,
in its sole opinion, considers a request from a Governmental Authority for
additional data and information in connection with the HSR Act to be unduly
burdensome, UAPI and TCI-E may terminate this Agreement.

         6.7     Further Assurances. Each of the parties to this Agreement will
execute such documents and other instruments and take such further actions as
may be reasonably required or desirable to carry out the provisions of this
Agreement and consummate the transactions contemplated by this Agreement or, at
and after the Closing Date, to evidence the consummation of the transactions
contemplated by this Agreement. Upon the terms and subject to the conditions of
this Agreement, each of the parties to this Agreement will take or cause to be
taken all actions and to do or cause to be done all other things necessary,
proper, or advisable to consummate and make effective as promptly as
practicable the transactions contemplated by this Agreement and to obtain in a
timely manner all necessary waivers, consents and approvals and to effect all
necessary registrations and filings.

         6.8     Tax Matters.

                 (a)      UAPI Obligations.

                          (i)     UAPI will be liable for, will pay, and will
indemnify and hold the Surviving Corporation harmless against, all Taxes
payable by TCI-E attributable to any taxable period ending at or before the
Effective Time ("TCI-E Taxes") and any liabilities, losses, damages, costs and
expenses (including court costs and reasonable professional fees incurred in
the investigation, defense or settlement of any claims covered by this
indemnity) attributable to any such TCI-E Taxes.

                          (ii)    UAPI will be entitled to any credits or
refunds of TCI-E Taxes payable or allocable to TCI-E or its shareholders at any
time, and UAPI will indemnify and hold harmless the Surviving Corporation
against any subsequent disallowance of such credits or refunds.

                          (iii)   UAPI will be responsible for the preparation
and filing of all Tax Returns relating to TCI-E Taxes for all taxable periods
that end at or before the Effective Time, including returns with respect to
such periods that are due after the Closing Date, and UAPI will be responsible
for the payment of all Taxes payable by TCI-E shown to be due thereon.

                          (iv)    UAPI will be designated as the agent for
TCI-E with respect to TCI-E Taxes, and will have the sole authority to deal
with any matters relating to TCI-E Taxes, including the filing of amended
returns, except that such authority will not include a change of accounting
method or revocation of tax elections that reasonably could be expected to have
an adverse effect on the Surviving Corporation after the Effective Time.

                          (v)     Acquiror will promptly inform UAPI whenever
any taxing authority asserts a claim, makes an assessment or otherwise disputes
the amount of any TCI-E Taxes. UAPI, at its cost and expense, will have the
right to control any resulting proceedings and to determine whether and when to
settle any such claim, assessment or dispute.

                 (b)      Acquiror Obligations.

                          (i)     Acquiror will be liable for, will pay, and
will indemnify and hold UAPI and its Affiliates harmless against, all Taxes (A)
payable by the Surviving Corporation attributable to any taxable period
beginning at or after the Effective Time or (B) resulting from the failure of
the Merger to qualify as a tax-free reorganization under Section 368(a) of the
Code to the extent such failure results from any action or omission by
Acquiror, and, in each case, any and all liabilities, losses, damages, costs
and expenses (including court costs and reasonable professional fees incurred
in the investigation, defense or settlement of any claims covered by this
indemnity) attributable to any such Taxes.





                                      -17-
<PAGE>   22
                          (ii)    Whenever any taxing authority asserts a claim
or makes an assessment for Taxes for which Acquiror is or may be liable under
Section 6.8(b)(i), UAPI will promptly inform Acquiror. Acquiror, at its cost
and expense, will have the night to control any resulting proceedings and to
determine whether and when to settle any such claim, assessment or dispute.

                 (c)      Other Taxes.     Except as otherwise provided in
Section 6.8(a) and Section 6.8(b), all Taxes will be the responsibility of the
taxpayer on which they are imposed, and any refunds and credits of Taxes will
be for the account of the taxpayer responsible for such Taxes.

                 (d)      Cooperation. The parties will cooperate with each
other in a timely manner in the preparation and filing of any Tax Returns, the
payment of any Taxes in accordance with this Agreement, the conduct of any
audit or other proceeding and otherwise to effect the provisions of this
Agreement relating to Taxes. Each party will execute and deliver such powers of
attorney and make available such other documents as are necessary to carry out
the intent of this Section 6.8. Each party will notify the other party of any
audit adjustments that do not result in a tax liability to that party but can
reasonably be expected to affect Tax Returns of the other party.

                 (e)      Retention of Records. Acquiror, TCI-E and UAPI will
(i) retain records, documents, accounting data and other information (including
computer data) necessary for the preparation and filing of all Tax Returns or
the audit of such returns and (ii) give to each other reasonable access to such
records, documents, accounting data and other information (including computer
data) to its personnel (and will insure their cooperation) and to its premises,
for the purpose of the review or audit of such Tax Returns to the extent
relevant to an obligation or liability of a party under this Agreement.

                 (f)      Payments, Disputes. Except as otherwise provided in
this Section 6.8, any amounts owed by any party to any other party under this
Section 6.8 will be paid within 15 days after notice from the party entitled to
such payment. If any party entitled to indemnification under this Section 6.8
has not paid the amount for which such party is entitled to indemnification and
such amount is being contested before the appropriate Governmental Authority in
good faith, the indemnifying party will not be required to make payment to the
indemnified party until an appropriate Governmental Authority determines
finally that payment is due. If the parties cannot agree on any calculation of
any liabilities under this Section 6.8, such calculation (but not the
determination of whether any liability in fact exists) will be made by an
independent public accounting firm acceptable to the disputing parties. The
decision of such firm will be final and binding. The fees and expenses incurred
in connection with such calculation will be borne equally by the disputing
parties.

                 (g)      Termination of Liabilities. Notwithstanding any other
provision in this Agreement, the liabilities of UAPI and Acquiror for any Taxes
under this Section 6.8 will apply only to Taxes properly assessed before the
expiration of the applicable statute of limitations for such Taxes.





                                      -18-
<PAGE>   23
                 (h)      Other Covenants. Neither Acquiror nor any of its
Affiliates will take any action or fail to take any action if such action taken
by Acquiror or any of its Affiliates or such failure to act by Acquiror or any
of its Affiliates would cause the Merger not to qualify as a reorganization
under Section 368(a) of the Code.

         6.9     Board Representation.

                 (a)      Initial Appointments. Acquiror will take such action
as may be required to cause one designee of UAPI and one designee of TCI Turner
Preferred, Inc. to be appointed to serve as directors of Acquiror, effective as
of the Effective Time, until their successors are duly elected and qualified.

                 (b)      Subsequent Action. So long as UAPI or any one or more
of its Affiliates, in the aggregate, beneficially own (within the meaning of
Rule 13d-3 under the Exchange Act) at least 20% of the outstanding shares of
Acquiror Common Stock at the date on which the Board of Directors of Acquiror
selects its proposed nominee for election to the Board of Directors (the
"Selection Date"), Acquiror will use its reasonable best efforts, consistent
with the fiduciary duties of its Board of Directors and applicable law: (i) to
include in its proxy statement for each meeting of Acquiror's stockholders at
which directors are to be elected a recommendation by Acquiror's Board of
Directors that one person designated by UAPI and one person designated by TCI

any covenant, agreement or obligation of TCI-E or UAPI contained in this

the conduct of the business of TCI-E, which act, omission, event or
circumstance occurred or existed prior to the Effective Time, other than any
liability or obligation of TCI-E under the instruments and agreements
evidencing the Note Rights (the "Assumed Liabilities"); and

                 (b)      all claims, actions, suits, proceedings, demands,
judgments, assessments, fines, interest, penalties, costs and expenses
(including settlement costs and reasonable legal, accounting, experts' and
other fees, costs-and expenses) incident or relating to or resulting from any
of the foregoing.

         9.2     Indemnification by Acquiror. Acquiror will indemnify, defend
and hold harmless UAPI and its Affiliates, and the shareholders, directors,
officers, employees, agents, successors and assigns of any of such Persons,

<PAGE>   28
"Action"), which Action is subject to indemnification under this Agreement,
such party (the "Indemnified Party") will give reasonable written notice to the
party from whom indemnification is claimed (the "Indemnifying Party"). The
Indemnified Party will 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, (a)
admits in writing to the Indemnified Party the Indemnifying Party's liability
to the Indemnified Party for such Action under the terms of this Article IX,
(b) notifies the Indemnified Party in writing of the Indemnifying Party's
intention to assume such defense, (c) provides evidence reasonably satisfactory

Action in accordance with this Agreement in any manner that such party
reasonably may request. If the Indemnifying Party so assumes the defense of any
such Action. the Indemnified Party will have the right to employ separate
counsel and to participate in (but not control) the defense, compromise or
settlement of the Action, but the fees and expenses of such counsel will be at
the expense of the Indemnified Party unless (i) the Indemnifying Party has
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 is advised by its counsel that there may be one or more defenses
available to it which are different from or additional to those available to
the Indemnifying Party, and in any such case that portion of the fees and
expenses of such separate counsel that are reasonably related to matters
covered by the indemnity provided in this Article IX will be paid by the
Indemnifying Party. No Indemnified Party will settle or compromise any such
Action for which it is entitled to indemnification under this Agreement without
the prior written consent of the Indemnifying Party, unless the Indemnifying
Party has failed, after reasonable notice, to undertake control of such Action
in the manner provided in this Section 9.3. No Indemnifying Party will settle
or compromise any such Action (A) in which any relief other than the payment of
money damages is sought against any Indemnified Party or (B) in the case of any
Action relating to the Indemnified Party's liability for any Tax, if the effect
of such settlement would be an increase in the liability of the Indemnified
Party for the payment of any Tax for any period beginning after the Closing
Date, unless the Indemnified Party consents in writing to such compromise or
settlement.
