collectively as the "COMPANIES" and individually as a "COMPANY", and DMX and
Purchaser will be referred to collectively as the "SHAREHOLDERS" and
individually as a "SHAREHOLDER".

     WHEREAS, the Companies are wholly owned direct and indirect subsidiaries of
DMX;

     WHEREAS, the Companies are in significant financial difficulty, and without
additional financial support will be placed into insolvency proceedings;
Purchaser has informed the Board of Directors of DMX that in his opinion the
business operations of the Companies are viable and potentially valuable; the
Board of Directors of DMX has determined that DMX will not provide any further
financial support for the Companies;

     WHEREAS, Purchaser has offered to use his best efforts to secure other
financing to permit the Companies to continue operations and, if Purchaser is
able to effect an agreement with the creditors and potential equity investors to
reorganize the operations of the Companies (the "REORGANIZATION"), to acquire
certain interests in the Companies;

     WHEREAS, in connection with the acquisition by Purchaser of certain
interests in the Companies, the ownership of DMX-NV and DMX-UK will be
restructured to make DMX-NV a subsidiary of DMX-UK, and the capital structure of
DMX-UK will be recapitalized;

     WHEREAS, Purchaser will deliver a continuing guaranty pursuant to which
Purchaser will agree to guarantee certain liabilities associated with the
operations of the Companies;

     WHEREAS, the Board of Directors of DMX believes it is in the best interest
of DMX's shareholders to enter into this Agreement and to provide Purchaser with
an opportunity to reorganize the operations of the Companies;

     WHEREAS, if Purchaser is unable to effect the Reorganization, then DMX will
subscribe for shares of a corporation newly organized by Purchaser to effect the
<PAGE>
 
distribution of the DMX digital audio service in Europe, pursuant to that
certain Subscription and Shareholders Agreement of even date herewith (the

          promissory note payable by DMX to the order of TCI-Euromusic, Inc.,
          which note was acquired by DMX in the merger of TCI-Euromusic, Inc.
          with and into DMX, including all unpaid interest accrued thereon (the
          entire note shall be referred to as the "NOTE"), together with a
          corresponding interest in the rights of DMX pursuant to any
          instruments or loan agreements associated with the Note (the

          (iii) a 90 percent interest in all other outstanding indebtedness, if

applicable Blue Sky laws (or taking such action as may be necessary to secure an
exemption from qualification, if available) of the offer and sale of the

in a timely manner prior to or promptly following the Closing.  Purchaser will
cooperate in obtaining any such qualification or exemption.

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

Instruments, or the Indebtedness, and if such amendment, compromise, or
forgiveness (i) occurs concurrently with the Closing, (ii) occurs pursuant to
binding contracts in effect at the time of the Closing, (iii) occurs within six
months of the Closing and is part of the Reorganization, or (iv) occurs as part

amend, compromise, or forgive the interests that it has retained in the Note,
the Instruments, and the Indebtedness in the same manner, in a proportionate
amount, and for the same consideration, if any, in a proportionate amount.

DMX-UK, or DMX-NV to any person for any reason or purpose, except that (i) after
the consummation of transactions contemplated by this Agreement, Purchaser may
use or disclose such information related to the Companies, (ii) Purchaser may
disclose information to the extent that disclosure of such information is

will keep such information confidential, (iii) such information is or becomes
publicly available otherwise than by disclosure in violation of this Section

Capital by providing to the contributors of such funds, services, or property,
equity interests in DMX-UK (or a successor company) either through the issuance
of shares by DMX-UK or from the Purchased Interests held by Purchaser after the
Closing; provided, however, that Purchaser shall have no affirmative obligation
to provide the Initial Capital other than through the use of newly issued stock
of DMX-UK and the Purchased Interests.  Such arrangements shall not create any
liability of DMX-UK to Purchaser.  After DMX-UK has received the Initial
Capital, Purchaser shall have no further obligation under this Section 5.2.5 to
dispose of the Purchased Interests for the benefit of the Companies.

          5.2.6  OWNERSHIP OF DMX-NV.  For so long as DMX or any transferee

provided, however, that after such time as Purchaser is no longer in control of
DMX-UK, Purchaser shall be obligated under this Section 5.2.6 only to use his
best efforts to cause DMX-UK to maintain such ownership.

for ten years or any applicable limitation period, including extensions thereof,
whichever is longer.  The Companies shall afford to DMX and its counsel,
accountants and other representatives reasonable access upon prior written
notice to all such books, corporate records and other documents, including, at
DMX's expense, copies of relevant documents.  In lieu of retaining any such

Common Shares into which the Preference Shares may be converted), DMX-UK (or any
successor company) shall include in the slate of nominees recommended by DMX-
UK's management to shareholders for election as directors at each annual meeting
of its shareholders, one nominee designated by DMX.  In the event that any such
designee of DMX shall cease to serve as a director for any reason (including
removal for cause), DMX-UK or its successor shall use its best efforts to fill
such vacancy with a designee of DMX.

and bears a fixed dividend; (ii) securities offered to the public generally
pursuant to a registration statement or pursuant to Regulation A under the
Securities Act (or comparable provisions of foreign law); or (iii)  Common

     8.2  TAG-ALONG RIGHTS.
          ---------------- 

          8.2.1  RIGHT TO PARTICIPATE IN SALE.  If a Selling Shareholder, at any
                 ----------------------------                                   
time or from time to time, enters into an agreement (whether oral or written) to

Along Sale by selling up to the number of its shares of Stock (the "TAG-ALONG
ALLOTMENT") equal to the product of (A) the total number of shares of Stock

immediately prior to the Tag-Along Sale.  Any such sales by the Tag-Along
Sellers shall be on the same terms and conditions as the proposed Tag-Along Sale
by the Selling Shareholder.  For purposes of this calculation, shares of
Preference or other securities convertible into Common Shares shall be treated
as the equivalent of the number of Common Shares into which such Preference or
other securities could be converted.

          8.2.2  EXCEPTIONS TO TAG-ALONG RIGHTS.  The foregoing notwithstanding,
                 ------------------------------                                 
Section 8.2 and Section 8.4 shall not apply to any Transfer of shares of Stock

satisfaction of indebtedness that arose prior to the Closing Date, (iii) that
occurs concurrently with the Closing, (iv) that occurs pursuant to a binding

or otherwise as part of an arrangement with creditors of the Companies, or (vii)
that occurs as consideration for the contribution of the Initial Capital as
described in Section 5.2.5, above.

          8.2.3  PROCEDURES FOR TAG-ALONG SALE.  The Selling Shareholder shall
                 -----------------------------                                
promptly provide each Tag-Along Seller with written notice (the "SALE NOTICE")
setting forth the terms and conditions of the proposed Transfer.  Each Tag-Along
Seller shall provide written notice (the "TAG-ALONG NOTICE") to the Selling
Shareholder and the Company within 15 days after receiving the Sale Notice.  The
Tag-Along Notice shall set forth the number of shares of Stock, if any, such
Tag-Along Seller elects to include in the Tag-Along Sale, which shall not exceed
the Tag-Along Allotment of such Tag-Along Seller as calculated pursuant to
Section 8.2.1, above.  The Selling Shareholder shall determine the aggregate
number of shares to be sold by each Tag-Along Seller in the Tag-Along Sale in
accordance with the terms hereof, and the Tag-Along Notices given by such Tag-
Along Sellers shall constitute their respective binding agreements to sell such
shares on the terms and conditions applicable to such sale (including the
requirements of this Section 8.2); provided, however, that the Tag-Along Sellers
                                   --------  -------                            
shall not be obligated to sell such shares in the Tag-Along Sale unless the sale
of the shares of the Selling Shareholders is consummated.  If the proposed
purchaser does not purchase the shares of the Tag-Along Sellers as required
under this Section 8.2, then the Selling Shareholder shall sell the entire
amount of the shares specified in the Sale Notice, and shall implement the
proposed Tag-Along Sale by purchasing from the Tag-Along Sellers the number of
shares specified by each Shareholder in its Tag-Along Notice; provided, however,
that the Selling Shareholder shall not be obligated to purchase such shares if
the sale specified in the Sale Notice is not consummated.

                                     -18-
<PAGE>
 
     If a Tag-Along Notice is not received by the Selling Shareholder from any
of the Tag-Along Sellers within the 15-day period specified above, the Selling
Shareholder shall have the right to sell or otherwise transfer the Stock to the
proposed purchaser without any participation by such other Shareholders, but
only on the terms and conditions stated in the notice to such Tag-Along Sellers
and only if such sale occurs not later than 90 days following the expiration of
the 15-day period specified above.

     8.3   APPLICATION OF TAG-ALONG RIGHTS TO INDIRECT TRANSFER OF STOCK.
           -------------------------------------------------------------  
If (i) a Selling Shareholder exchanges Stock for an equity interest in any
entity, or (ii) a Selling Shareholder sells Stock to any entity that is owned or
controlled by the Selling Shareholder and the Stock constitutes more that 25
percent of the fair market value of the assets of the entity, then the Tag-Along
Sellers' rights to participate in a Transfer shall attach to any Transfer of the
Selling Shareholder's interest in that entity.  If the proposed purchaser

shall implement the proposed Tag-Along Sale by purchasing from the Tag-Along
Sellers the number of shares of Stock specified by each Shareholder in its Tag-
Along Notice; provided, however, that the Selling Shareholder shall not be

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

          8.4.1  RIGHT TO REQUIRE SALE.  If Purchaser and all Purchaser
                 ---------------------                                 
Affiliates agree to sell 100 percent of the Common Shares and other stock of
DMX-UK held by them to a third person who is not affiliated with or related to
Purchaser in any manner that could allow Purchaser or a Purchaser Affiliate to
enjoy an economic benefit attributable to the sale that would not be enjoyed by
DMX (any such party, a "THIRD PARTY", and any such transaction, a "DRAG-ALONG
SALE"), then DMX or any Permitted Transferee of DMX (a "DRAG-ALONG SELLER"),
subject to Sections 8.4.1, 8.4.2, and 8.4.3 shall sell to such Third Party, upon
the demand by Purchaser, 100 percent of Common Shares and Preference held by the
Drag-Along Seller on the date of the Drag-Along Notice (as defined in Section
8.4.2, below), at the same proportionate price and on the same terms and
conditions as Purchaser has agreed with such Third Party; provided, however,
                                                          --------  ------- 
that the terms of such Drag-Along Sale shall provide (i) that the only
representation and warranty or covenant which any Drag-Along Seller shall be
required to make in connection with the Drag-Along Sale is a representation and
warranty with respect to its own ownership of the shares to be sold by it and
its ability to convey title thereto free and clear of liens, encumbrances or
adverse

                                     -19-
<PAGE>
 
claims and (ii) that the liability of any Drag-Along Seller with respect to any
representation and warranty made in connection with the Drag-Along Sale is the
several liability of that Drag-Along Seller (and not joint with any other
person) and that such liability is limited to the amount of proceeds actually
received by that Drag-Along Seller in the Drag-Along Sale.  If the Drag-Along
Sale is in the form of a merger transaction, each Drag-Along Seller shall vote
its shares in favor of such merger and shall not exercise any rights of
appraisal or dissent afforded under applicable law.

          8.4.2  DRAG-ALONG NOTICE.  Prior to making any Drag-Along Sale, if
                 -----------------                                          
Purchaser elects to exercise the rights afforded under Section 8.4, Purchaser
shall provide each Drag-Along Seller with written notice (the "DRAG-ALONG
NOTICE") not less than twenty (20) days prior to the proposed date of the Drag-
Along Sale (the "DRAG-ALONG SALE DATE").  The Drag-Along Notice shall set forth:
(i) the name and address of the Third Party; (ii) the proposed amount and form
of consideration to be paid per share and the terms and conditions of payment
offered by the Third Party; (iii) the aggregate number of shares held of record
by Purchaser as of the date of the Drag-Along Notice; (iv) the Drag-Along Sale
Date; and (v) confirmation that the proposed Third Party has agreed to purchase
the Drag-Along Seller's Stock in accordance with the terms hereof.
 
          8.4.3  NON-CASH CONSIDERATION.  The provisions of Section 8.4 shall
                 ----------------------                                      
not apply unless the only consideration to be received in the Drag-Along Sale
consists of cash and securities for which an active trading market exists (it
being understood that an active trading market shall be conclusively deemed to
exist for a particular security if that security is listed on the New York Stock
Exchange, the American Stock Exchange, the NASDAQ National Market System, the
NASDAQ Small Cap Market, the UK Stock Exchange, or the Alternative Investment
Market and that the failure of the security to be so listed shall not per se
                                                                      --- --
determine that an active trading market does not exist).

          8.5  TERMINATION OF TAG-ALONG AND DRAG-ALONG RIGHTS.  Sections 8.2,
               ----------------------------------------------                
8.3 and 8.4 shall terminate (i) with respect to Stock held by DMX or a Permitted
Transferee of DMX that is transferred to any transferee other than a Permitted
Transferee, when that Stock is so transferred, or (ii) with respect to all the
Stock held by DMX and all Permitted Transferees of DMX, at such time after DMX-
UK's initial registered public offering as all Stock held by DMX and its
Permitted Transferees can be sold within a given three-month period without
compliance with the registration requirements of the Securities Act pursuant to
Rule 144, or another applicable exemption of equivalent effect, supported by a
written opinion of legal counsel for DMX-UK which shall be

                                     -20-

reasonably satisfactory in form and substance to legal counsel for DMX.

or any similar federal statute and the rules and regulations of the Commission
thereunder, all as the same shall be in effect at the time.

     "HOLDER" shall mean DMX or a transferee of registration rights under
      ------

or ordering of the effectiveness of such registration statement.

      ----------------------                                                
stock of DMX-UK held by DMX after the consummation of the transactions

stock or preference stock upon any stock split, stock dividend,
recapitalization, conversion, or similar event, which have not been sold to the
public.

     "REGISTRATION EXPENSES" shall mean all expenses incurred by DMX-UK in
      ---------------------

any holder.

     1.2  REQUESTED REGISTRATION.
          ---------------------- 

          1.2.1 PARITY WITH PURCHASER.  DMX-UK shall provide Holder with the
                ---------------------                                       
same demand registration rights, if any, that are provided to Purchaser or any
Purchaser Affiliate under any existing contract or any contract entered into in
the future by DMX-UK and Purchaser or any Purchaser Affiliate.  DMX-UK shall
provide DMX with notice of any such registration rights.

          1.2.2 MODIFICATIONS AS APPLIED TO DMX.  If the registration rights
                -------------------------------                             
that are used to define the demand registration rights of Holder call for
calculations or determine rights based on the number of shares of DMX-UK held by
Purchaser or any Purchaser Affiliate or based upon a minimum number of shares
which must be registered, such provision shall apply to Holder with the
following modification.  Any such provision shall apply to Holder using as a
standard that number of shares of DMX-UK which bears the same relationship to
the total number of shares of DMX-UK owned by Holder as the number of shares
called for in that provision bears to the total number of shares of DMX-UK owned
by Purchaser or any Purchaser Affiliate.

     1.3  DMX-UK REGISTRATION.
          ------------------- 

          1.3.1 NOTICE OF REGISTRATION.  If, at any time or from time to time,
                ----------------------                                        
DMX-UK shall determine to register any of its securities, either for its own
account or the account of a holder or holders of DMX-UK's securities, other than
(i) a registration relating solely to employee benefit plans on Form S-1 or S-8
or similar forms which may be promulgated in the future, (ii) a registration on
Form S-4 or similar form which may be promulgated in the future relating solely
to a Securities and Exchange Commission Rule 145 transaction, or (iii) a
registration undertaken pursuant to Section 1.2.1, above, DMX-UK will:

          (a) promptly give to each Holder written notice thereof (which shall
include a list of the jurisdictions in which DMX-UK intends to attempt to
qualify such securities under the applicable Blue Sky or other state securities
laws); and

          (b) include in such registration (and any related qualification under
Blue Sky laws or other compliance), and in any underwriting involved therein,
all Registrable Securities specified in a written request or requests made by
any Holder or Holders within 20 days after receipt by such Holder of such
written notice from DMX-UK.

                                      -2-
<PAGE>
 
          1.3.2  UNDERWRITING.  If the registration of which DMX-UK gives notice
                 ------------                                                   
is for a registered public offering involving an underwriting, DMX-UK shall so
advise the Holders as a part of the written notice given pursuant to Section
1.3.1. In such event the right of any Holder to registration pursuant to Section
1.3 shall be conditioned upon such Holder's agreeing to participate in such
underwriting and in the inclusion of such Holder's Registrable Securities in the
underwriting to the extent provided herein. All Holders proposing to distribute
their securities through such underwriting shall (together with DMX-UK and the
other holders distributing their securities through such underwriting) enter
into an underwriting agreement in customary form with the underwriter or
underwriters selected for such underwriting by DMX-UK or by the other holders
whose securities are being registered. Notwithstanding any other provision of
this Section 1.3, if the underwriter determines that marketing factors require a
limitation of the number of shares to be underwritten, DMX-UK shall so advise
all Holders and the other holders distributing their securities through such
underwriting. The number of Registrable Securities and other securities that may
be included in the registration and underwriting shall be allocated among all
holders thereof on the following basis: (i) first to the securities to be
registered by DMX-UK for its own account, if any; (ii) second, to holders of
securities other than Purchaser or any Purchaser Affiliate who are exercising
contractual "demand" registration rights; (iii) then to holders of securities
(including Holders, Purchaser, and any Purchaser Affiliate) who are exercising
contractual, "piggyback" registration rights; and (iv) finally to other holders
of securities of DMX-UK. As among those holders of equal priority suffering such
cut-back, the cut-back shall be in proportion, as nearly as practicable, to the
respective amounts of securities entitled to inclusion in such registration held
by such holders at the time of filing the registration statement. If at any time
Purchaser or any Purchaser Affiliate is granted registration rights that would
provide them higher priority or more protection against a cut-back than is
described in the preceding two sentences, then DMX-UK shall afford the same
priority or protection to the Holders. If any Holder disapproves of the terms of
any such underwriting, he may elect to withdraw therefrom by written notice to
DMX-UK and the underwriter. Any securities excluded or withdrawn from such
underwriting shall be withdrawn from such registration.

     1.4  EXPENSES OF REGISTRATION.  All Registration Expenses incurred in
          ------------------------                                        
connection with any registration, qualification or compliance pursuant to
Sections 1.3 shall be borne pro rata by those selling securities pursuant to
such registration.  All Registration Expenses incurred in connection with
registration, qualification or compliance pursuant to Section 1.2.1 shall be
borne by DMX-UK and the Holders selling securities pursuant to such registration
on the same basis as

                                      -3-
<PAGE>
 
provided in the registration rights afforded to Purchaser or any Purchaser
Affiliate.  All Selling Expenses relating to securities registered by the
Holders or other holders shall be borne by the Holders or other holders of such
securities pro rata on the basis of the number of shares so registered.

     1.5  REGISTRATION PROCEDURES.  In the case of each registration,
          -----------------------                                    
qualification or compliance effected by DMX-UK pursuant to this Exhibit 7.1,
DMX-UK will:

          (a) Keep each Holder advised in writing as to the initiation of each
registration, qualification and compliance and as to the completion thereof.

          (b) Keep such registration, qualification or compliance effective for
a period of 120 days or until the Holder or Holders have completed the
distribution described in the registration statement relating thereto, whichever
first occurs.

          (c) Furnish such number of prospectuses and other documents incident
thereto as a Holder from time to time may reasonably request.

          (d) Prepare and file with the SEC such amendments and supplements to
such registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
Act with respect to the disposition of all securities covered by such
registration statement.

          (e) Use its best efforts to register and qualify the securities
covered by such registration statement under such other securities or Blue Sky
laws of such jurisdictions as shall be reasonably requested by the Holders,
provided that DMX-UK shall not be required in connection therewith or as a
condition thereto to qualify to do business or to file a general consent to
service of process in any such states or jurisdictions.

          (f) In the event of any underwritten public offering, enter into and
perform its obligations under an underwriting agreement, in usual and customary
form, with the managing underwriter of such offering.  Each Holder participating
in such underwriting shall also enter into and perform its obligations under
such an agreement.

          (g) Notify each Holder of Registrable Securities covered by such
registration statement at any time when a prospectus relating thereto is
required to be delivered under the Act of the happening of any event as a result
of which the prospectus included in such registration statement, as then in
effect, includes an untrue statement of material fact or omits to state a
material fact required to be stated therein or

                                      -4-
<PAGE>
 
necessary to make the statements therein not misleading in the light of the
circumstances then existing.

          (h) At the request of any Holder requesting registration of
Registrable Securities pursuant to this Exhibit 7.1, on the date that such
Registrable Securities are delivered to the underwriters for sale in connection
with an underwritten registration pursuant to this Exhibit 7.1, (i) furnish an
opinion dated such date, of the counsel representing DMX-UK for the purposes of
such registration, addressed to the underwriters and, if such counsel is also
representing the Holders requesting registration of Registrable Securities, to
such Holders, and (ii) use its best efforts to furnish a letter dated such date,
from the independent certified public accountants of DMX-UK, addressed to the
underwriters and to the Holders.

     1.6  INDEMNIFICATION.
          --------------- 

          1.6.1 INDEMNIFICATION BY DMX-UK.  DMX-UK will indemnify and defend
                -------------------------                                   
each Holder, each of its officers and directors and partners, and each person
controlling such Holder within the meaning of Section 15 of the Securities Act,
with respect to which registration, qualification or compliance has been
effected pursuant to this Exhibit 7.1, and each underwriter, if any, and each
person who controls any underwriter within the meaning of Section 15 of the
Securities Act, against all expenses, claims, losses, damages and liabilities
(or actions in respect thereof), including any of the foregoing incurred in
settlement of any litigation, commenced or threatened, arising out of or based
on any untrue statement (or alleged untrue statement) of a material fact
contained in any registration statement, prospectus, offering circular or other
document, or any amendment or supplement thereto, incident to any such
registration, qualification or compliance, or based on any omission (or alleged
omission) to state therein a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances in which
they were made, not misleading, or any violation by DMX-UK of any rule or
regulation promulgated under the Securities Act applicable to DMX-UK and
relating to action or inaction required of DMX-UK in connection with any such
registration, qualification or compliance, and will pay to each such Holder,
each of its officers and directors and partners, and each person controlling
such Holder, each such underwriter and each person who controls any such
underwriter, as incurred, any legal and any other expenses reasonably incurred
in connection with investigating, preparing or defending any such claim, loss,
damage, liability or action; provided, however, that DMX-UK will not be liable
to any such case to the extent that any such claim, loss, damage, liability or
expense arises out of or is based on any untrue statement or omission or alleged
untrue statement or omission, made in reliance upon and in conformity with
written

                                      -5-
<PAGE>
 
information furnished to DMX-UK by an instrument duly executed by a Holder or
underwriter and stated to be specifically for use therein or any violation by a
Holder or underwriter of any rule of regulation promulgated under the Securities
Act applicable to such Holder or such underwriter in connection with such
registration.

          1.6.2 INDEMNIFICATION BY HOLDERS.  Each Holder will, if Registrable
                --------------------------                                   
Securities held by such Holder are included in the securities as to which such
registration, qualification or compliance is being effected, indemnify and
defend DMX-UK, each of its directors and officers, each underwriter, if any, of
DMX-UK's securities covered by such a registration statement, each person who
controls DMX-UK or such underwriter within the meaning of Section 15 of the
Securities Act, and each other such Holder, each of its officers and directors
and partners and each person controlling such Holder within the meaning of
Section 15 of the Securities Act, against all expenses, claims, losses, damages
and liabilities (or actions in respect thereof) including any of the foregoing
incurred in settlement of any litigation commenced or threatened, arising out of
or based on any untrue statement (or alleged untrue statement) of a material
fact contained in any such registration statement, prospectus, offering circular
or other document, or any amendment or supplement thereto, incident to any such
registration, qualification or compliance or based on any omission (or alleged
omission) to state therein a material fact required to be stated therein or
necessary to make the statements therein, in the light of the circumstances in
which they were made, not misleading, or any violation by such Holder of any
rule or regulation promulgated under the Securities Act applicable to such
Holder in connection with such registration, and will pay to DMX-UK, such other
Holders, such directors, officers, partners, persons, underwriters or control
persons, as incurred, any legal or any other expenses reasonably incurred in
connection with investigating, preparing or defending any such claim, loss,
damage, liability or action, in each case to the extent, but only to the extent,
that such expenses, claims, losses, damages or liability arise out of or are
based upon (i) such an untrue statement (or alleged untrue statement) or
omission (or alleged omission) is made in such registration statement,
prospectus, offering circular or other document or any amendment or supplement
thereto in reliance upon and in conformity with written information furnished to
DMX-UK by an instrument duly executed by such Holder and stated to be
specifically for use therein, or (ii) any such violation by such Holder of any
rule or regulation promulgated under the Securities Act applicable to such
Holder in connection with such registration; provided, however, that the
obligations of such Holder hereunder shall be limited to an amount equal to the
greater of (x) the proceeds to such Holder of Registrable Securities sold as
contemplated herein, or (y) the out-of-pocket expenses incurred by DMX-UK (not
including defense costs or amounts

                                      -6-
<PAGE>
 
paid to those claiming against DMX-UK) in connection with any such registration
that cannot by completed as a result of the untrue statement or violation of
such Holder that gives rise to the indemnity obligation under this Section.

          1.6.3 PROCEDURES.  Each party entitled to indemnification under this
                ----------                                                    
Section 1.6 (the "Indemnified Party") shall give notice to the party required to
provide indemnification (the "Indemnifying Party") promptly after such
Indemnified Party has actual knowledge of any claim as to which indemnity may be
sought, and shall permit the Indemnifying Party to assume the defense of any
such claim or any litigation resulting therefrom, provided that counsel for the
Indemnifying Party, who shall conduct the defense of such claim or litigation,
shall be approved by the Indemnified Party (whose approval shall not be
unreasonably withheld), and the Indemnified Party may participate in such
defense at its own expense, and provided further that the failure of any
Indemnified Party to give notice as provided herein shall not relieve the
Indemnifying Party of its obligations under this Section 1.6 unless such failure
resulted in actual detriment to the Indemnifying Party.  Notwithstanding the
above, however, if representation of one or more Indemnified Parties by the
counsel retained by the Indemnifying Party would be inappropriate due to actual
conflicting interests between such Indemnified Parties (the "Conflicting
Indemnified Parties") and any other party represented by such counsel in such
proceeding, then such Conflicting Indemnified Parties shall have the right to
retain one separate counsel, chosen by the holders of a majority of the
Registrable Securities included in the registration, at the expense of the
Indemnifying Party.  No Indemnifying Party, (i) in the defense of any such claim
or litigation, shall, except with the consent of each Indemnified Party, which
consent shall not be unreasonably withheld, consent to entry of any judgment or
enter into any settlement which does not include as an unconditional term
thereof the giving by the claimant or plaintiff to such Indemnified Party of a
release from all liability in respect to such claim or litigation, or (ii) shall
be liable for amounts paid in any settlement if such settlement is effected
without the consent of the Indemnifying Party, which consent shall not be
unreasonably withheld.

     1.7  INFORMATION BY HOLDER.  The Holder or Holders of Registrable
          ---------------------                                       
Securities included in any registration shall furnish to DMX-UK such information
regarding such Holder or Holders and the distribution proposed by such Holder or
Holders as DMX-UK may request in writing and as shall be required in connection
with any registration, qualification or compliance referred to in this Exhibit
7.1.

     1.8  RULE 144 REPORTING.  With a view to making available the benefits of
          ------------------                                                  
certain rules and regulations of the Commission which may at any time permit the
sale of the

                                      -7-
<PAGE>
 
Restricted Securities to the public without registration, after such time as a
public market exists for the common stock of DMX-UK, DMX-UK agrees to each of

2.   RIGHTS OF DMX-UK WITH RESPECT TO THE CHANNELS

     2.1  GRANT OF LICENSE.  Subject to the terms of this Agreement, DMX hereby
grants to DMX-UK and DMX-UK hereby accepts, the exclusive, non-transferable,
royalty-free license and right during the Term to market, distribute and license
the Channels to Subscribers and to Use the signal of the Channels, the Service
Technology, and the Technical Accessories in the Territory.  This Agreement does
not give DMX-UK any right or license to distribute or to Use the Channels, the
Service Technology, or the Technical Accessories outside of the Territory.

     2.2  FAILURE TO EXPLOIT LICENSE.  DMX-UK agrees to Exploit the Channels in
substantially all of the Territory; provided, however, that DMX's only remedy
for the failure by DMX-UK to Exploit the Channels shall be to take the actions
described in this Section 2.2.  If DMX-UK fails to Exploit the Channels in a
substantial portion of the Territory, and does not cure such failure to Exploit
within ninety (90) days of notice by DMX, then at the conclusion of such ninety
day period the license granted pursuant to Sections 2.1 and 2.4 shall become a
non-exclusive license and DMX shall be relieved of its obligations under Section
2.10, below.  If DMX-UK fails to Exploit the Channels in any country that is a
part of the Territory, and does not cure such failure to Exploit within ninety
(90) days of notice by DMX, then at the conclusion of

                                      -4-
<PAGE>
 
such ninety day period the license granted pursuant to Section 2.1 and 2.4 shall
become a non-exclusive license with respect to such country and DMX shall be
relieved of its obligations under Section 2.10, below, with respect to such
country.  All or any part of the Territory that becomes non-exclusive pursuant
to this Section 2.2 shall be referred to as a "NON-EXCLUSIVE TERRITORY", and the
date on which that Non-Exclusive Territory becomes non-exclusive pursuant to
this Section 2.2 shall be referred to as the "NON-EXCLUSIVE DATE".  If DMX does
not Exploit the Channels within a Non-Exclusive Territory within 180 days of the
Non-Exclusive Date, and if DMX-UK does Exploit the Channels within that Non-
Exclusive Territory within 180 days of the Non-Exclusive Date, then the license
granted pursuant to Sections 2.1 and 2.4 shall again become an exclusive license
for that Non-Exclusive Territory and the rights of DMX-UK under Section 2.10,
below, with respect to that Non-Exclusive Territory shall be restored.

     2.3  SUBLICENSE.  During the Term DMX-UK shall be entitled to sublicense
third parties to redistribute the Channels in the Territory, provided that such
sublicensing does not entitle such sublicensee to do any act or thing which if
done by DMX-UK would be a breach of the terms of this Agreement.

     2.4  TECHNICAL ACCESSORIES.  During the Term and subject to the other
restrictions described in this Agreement, DMX-UK shall have the exclusive right
to Use in the Territory any Technical Accessories included within the signal of
the Channels for any lawful purpose, including, but not limited to close
captioning, games, sweepstakes, contests, advertising and promotions.  DMX-UK
shall obtain any license or authorization required under applicable law for such
use, and shall not use the Technical Accessories in a jurisdiction in any manner
which is not lawful in that jurisdiction.  If DMX-UK determines in its sole
discretion not to use any part of the Technical Accessories, DMX-UK may license
such Technical Accessories to DMX or to another third party for any lawful
purpose.

     2.5  CENSORSHIP AND PROGRAM SUBSTITUTION.  DMX acknowledges and agrees that
the Channels may be subject to censorship by certain government authorities and
may be edited by them or by DMX-UK according to guidelines and directives
prescribed by such authorities ("CONTENT SUPERVISION AUTHORITIES") prior to
distribution within certain countries in the Territory.  DMX-UK shall have the
right to edit programs and, with the prior approval of DMX where reasonably
possible, which approval shall not be unreasonably withheld, substitute programs
solely in order to comply with codes, practices, directives or orders from the
Content Supervision Authorities.  To enable DMX-UK to meet with and comply with
any governmental programming standards and practices and other governmental and
regulatory directives, DMX-UK may retransmit

                                      -5-
<PAGE>
 
the Channels with a delay from the time the signal is received.  Except as
expressly provided in this Agreement, including this Section 2.5, DMX-UK shall
use the Channels without insertion (whether of advertising or otherwise),
deletion, or editing.

     2.6  INSERTION OF LOGO AND MARK OF DMX-UK.  DMX-UK shall have the right to
use its own logo, station identity mark, trade name, service mark or other
identifiers within the Channels as part of its network identity and branding
within the DMX-UK Service.

     2.7  INCLUDING CHANNELS IN DMX-UK SERVICE; ADDITION OF CHANNELS.  DMX-UK
shall be entitled, in its sole discretion, to include any or all of the Channels
in the DMX-UK Service.  DMX-UK shall be entitled, at its sole discretion, to
create and distribute additional channels within the DMX-UK Service and within
the Territory; provided, however, that DMX shall have to right to approve
(acting reasonably) such additional channels that are distributed with the
Channels.  DMX-UK may request that DMX create such additional Channels or
Territory-Specific Channels on terms and conditions to be agreed between the
Parties, or DMX-UK may create such channels itself or through the engagement of
third parties.  Any such additional channels created by or on behalf of DMX-UK
shall be owned solely by DMX-UK.

     2.8  COMMERCIAL ANNOUNCEMENTS.  DMX-UK shall be entitled, in its sole
discretion, to include commercial announcements within the Channels distributed
to Commercial Establishments, so long as such commercial announcements relate
specifically to the Commercial Establishment to which such Channels are
distributed.  Furthermore, DMX-UK shall be entitled to include in the Channels
the same types of commercial announcements and/or advertisements that DMX
includes in the Channels as provided to its Customers.  Except as provided
herein, no commercial announcements will be included in any of the Channels.

     2.9  RESTRICTIONS ON USE.  In order to ensure the integrity of the Channels
and compliance with the restrictions that may be applicable to the underlying
programming, sound recording, music and statutory use permits, DMX-UK shall not,
and the rights granted herein shall not be interpreted to grant DMX-UK or any
other person any right to:

          2.9.1     Record, make or manufacture any recordings or other
          reproductions of any Channel for commercial use, other than to effect
          distribution as part of the DMX-UK Service; or

          2.9.2  Transmit, re-transmit or authorize the transmission or re-
          transmission of any Channel outside the Territory.

                                      -6-
<PAGE>
 
DMX-UK shall not distribute the Channels over any medium or in any manner that
does not permit DMX-UK to institute adequate controls to prevent the reception,
transmission or re-transmission of any Channel outside the Territory by any
person.  Controls imposed by DMX-UK that are equivalent to the controls imposed
by DMX in the United States on the same medium to prevent unauthorized
transmission or retransmission shall be deemed to be adequate controls for
purposes of the preceding sentence.  Notwithstanding anything else contained in
this Agreement, the transmission of the Channels outside the Territory solely
because a portion of the footprint of the satellite used by DMX-UK falls outside
the geographical boundaries of the Territory shall not violate DMX-UK's
obligations under this Agreement if (i) DMX-UK does not otherwise Exploit or Use
the Channels outside the Territory, and (ii) substantially all of the footprint
of the satellite used by DMX-UK falls within the Territory.

     2.10 NON-COMPETITION.  DMX agrees that during the Term it will not
distribute the Channels or any of them in the Territory via any medium, nor will
DMX authorize any other person to do the same.  Notwithstanding the foregoing,
DMX shall be entitled to distribute video channels or music services other than
the Channels in the Territory, so long as the format of such other music
services is not substantially similar to that of the Channels.

     2.11 DELETION OF CHANNEL.  At any time and from time to time, DMX shall be
entitled, in its sole discretion, to delete one or more Channels from the
Channels offered to its Customers, and upon such deletion such Channel shall
cease to be available to DMX-UK.  DMX may not delete a Channel pursuant to this
Section 2.11 unless, at least thirty days before the effective date of such
deletion, DMX provides to DMX-UK (i) notice of the deletion, (ii) one or more
disks inscribed with the music programming for the Channel as of the date of the
notice, and (iii) a copy of the software prepared by DMX to select the music for
such Channel; provided, however, that in order to delete a Channel, DMX shall
not be required to provide any software or other intellectual property that DMX
does not own or otherwise have right to transfer to DMX-UK.  The provisions of
Section 6.3 shall apply to the use by DMX-UK of any items provided pursuant to
this Section 2.11.

     2.12 ENHANCEMENTS AND MAINTENANCE.  DMX shall provide Enhancements and
Maintenance to DMX-UK at the same time as DMX provides Enhancements and
Maintenance to DMX's Customers.

3.   DELIVERY AND DISTRIBUTION

     3.1  DELIVERY OF THE CHANNELS.  DMX shall deliver to DMX-UK at the Delivery
Site digital audio signals of the Channels, to enable DMX-UK to Use the signal

DMX's Denver studio to the Designated Satellite.

     3.3  CHANGE IN DESIGNATED SATELLITE.   DMX-UK shall provide written notice
to DMX of any planned permanent change in the Designated Satellite not less than
ninety (90) days prior to such change.  If a temporary change in the Designated
Satellite is required, DMX and DMX-UK shall each use their reasonable efforts
(including the earliest practicable notice by DMX-UK to DMX of such events) to
avoid any interruption of or disruption in delivery of the Channels to the
Subscribers.  DMX-UK shall be responsible for all costs associated with any
permanent or temporary change in the Designated Satellite, including
administrative and technical costs of aligning or setting reception equipment.

4.   LICENSE OF TRADEMARKS

     4.1  LICENSE TO TRADEMARKS FOR PROMOTIONAL PURPOSES.  DMX hereby grants to
DMX-UK for the Trademark Term a non-exclusive, non-transferable, royalty-free
license to use the DMX Marks for the distribution, marketing and promotion of
the Channels to Subscribers and potential Subscribers within the Territory.

     4.2  APPROVAL RIGHTS.  DMX-UK shall not use the DMX Marks in distribution,
marketing, promotion or advertising without the prior written approval of such
use by DMX.  In its sole discretion, DMX shall be entitled to provide DMX-UK

to the use of the DMX Marks on such proposed Promotional Materials, and, in the
event of an objection, DMX shall state its reasons for such objection.  In the
event that DMX does not object to the use of the DMX Marks within such ten (10)
day period, such use shall be deemed to be approved

                                      -8-
<PAGE>
 
and the proposed Promotional Materials may be used.  Upon request, DMX-UK shall
provide DMX with samples of all approved Promotional Materials as used by DMX-

the Trademark Term or the termination of this Agreement ("TRADEMARK TERMINATION

Subscribers and potential Subscribers within the Territory, DMX-UK shall be
entitled to refer to the Channels in its promotional materials as "formerly

the Incremental Costs paid to DMX for the period to which such audit relates
have been over-reported by DMX by more than five percent (5%), in which case DMX
shall pay the cost of the audit.  All information obtained by DMX-UK as a result
of such audit shall be treated as Confidential Information in accordance with
the provisions of Section 7 of this Agreement.

permitted by this Agreement.   At no time shall DMX-UK adopt or use, without the
prior written consent of DMX, any variation of the DMX Marks or any work or mark
likely to be similar to, or confused with, the DMX Marks.  Any and all goodwill
arising from the use by DMX-UK of the DMX Marks shall inure solely to the
benefit of DMX.  As may be required by law, DMX-UK will at its expense record

authorities in Territory, and DMX will cooperate in effecting such recordation
and registration.  DMX-UK shall not assert any claim to the DMX Marks or such
goodwill, either during or after the Term of this Agreement, and DMX-UK shall
not take any action that could be detrimental to the goodwill associated with
the DMX Marks.

     to making such disclosure) and shall seek confidential treatment of such
     information;

          7.1.2  as part of its reporting or review procedure to its parent
     company, its auditors, its attorneys and potential investors; provided,

          8.2.3  DMX-UK is under no contractual or other legal obligation which

DMX-UK Service complies in all aspects with the regulatory requirements in the

10.  INDEMNIFICATION

     10.1 INDEMNIFICATION.  Each Party shall indemnify and hold the other Party
harmless from and against any and all claims, liabilities, costs and expenses,
including attorneys fees and costs, arising out of any breach by such Party of
any of its respective representations, warranties or covenants herein contained.
In addition, without limiting the foregoing, DMX-UK shall indemnify and hold DMX
harmless against any and all claims, liabilities, costs and expenses, including
attorneys fees and costs, arising from and in connection with (i) any non-
payment of any amounts payable in respect of copyrights, and music and sound
recording performance and reproduction rights, arising from the distribution of
the Channels in the Territory; (ii) any assertion by any third party that the
distribution, promotion, and other exploitation of the Channels, and any
programming contained therein, violate or infringe upon any rights of such third
party in the Territory, unless such third party is not a creditor (as of the
date of this Agreement), receiver or trustee of the Companies and the claims of
such third party derive from a purported grant of rights by DMX to the third
party that is inconsistent with this Agreement; or (iii) the failure of DMX-UK
to obtain or maintain proper governmental authority to distribute the Channels
in the Territory.

     10.2 PROCEDURE FOR INDEMNIFICATION.  The Party entitled to indemnification
hereunder (the "INDEMNIFIED PARTY") shall notify the other Party hereto (the
"INDEMNIFYING PARTY") in writing of the claim or action for which such indemnity
applies. The Indemnifying Party shall undertake the defense of any such claim or
action and permit the Indemnified Party to participate therein at the
Indemnified Party's own expense. The settlement of any such claim or action by
an Indemnified Party, without the Indemnifying Party's prior written consent,
shall release the Indemnifying Party from its obligations hereunder with respect
to such claim or action so settled.  The Indemnifying Party shall not settle or
otherwise dispose of any claim without the prior written consent of the
Indemnified Party, which consent shall not be unreasonably withheld.

     11.2  TERMINATION FOR BREACH.  This Agreement may be terminated by a party
(the "Noticing Party") as follows:

          11.2.1  thirty (30) days following written notice by the Noticing
     Party to the other Party (the "Noticed Party") of any material inaccuracy
     of a representation made by the Noticed Party herein or in the Stock
     Purchase Agreement or of a material breach by the Noticed Party of any of
     its obligations hereunder or under the Stock Purchase Agreement, if such
     misrepresentation or breach is not cured within the thirty (30) day period
     following such notice;

          11.2.2  immediately upon written notice by the Noticing Party to the
     Noticed Party if the Noticed Party has made a voluntary petition for
     protection under the bankruptcy laws, or if the Noticed Party has taken any
     similar action in consequence of debt;

          11.2.3  thirty (30) days following written notice by the Noticing
     Party to the Noticed Party if the Noticed Party has been the subject of the
     filing of an involuntary petition in bankruptcy, or if any distress or
     attachment is levied or any receiver is appointed in respect of the
     business or a substantial part of the property or assets of the Noticed
     Party, unless such petition, distress, attachment, or receiver is dismissed
     within such thirty-day period; or

          11.2.4  upon thirty (30) days prior written notice by the Noticing
     Party to the Noticed Party if any event of Force Majeure shall continue for
     a period of sixty (60) consecutive days.

The exercise of any right to termination under this Section 11.2 is not an
exclusive remedy, and the Noticing Party may in addition exercise any other
remedy available to it in law or equity.

foregoing, neither party shall by reason of the expiration or termination of
this Agreement be liable to the other for compensation or damage on account of
the loss of present or prospective profits on distribution or anticipated
distribution of the Channels, or expenditures, investments or commitments made
in connection therewith.  Upon the expiration or termination of this Agreement,
