ITEM 2:   ACQUISITION AND DISPOSITION OF ASSETS

     Pursuant to the letter agreement, dated as of May 19, 1999, the terms and
conditions of which had been previously reported in the Report on Form 8-K of
TCI Music, Inc. (the "Prior 8-K"), on July 15, 1999, MTV Networks ("MTVN"), a
division of Viacom International Inc. ("Viacom"), TCI Music, Inc. (the
"Company") and Liberty Media Corporation ("Liberty") entered into an
Organization Agreement and other related organizational and transactional
agreements and other documents pursuant to which the Company and MTVN formed
MTVN Online L.P., a Delaware limited partnership ("Music.co"). Music.co's
business will be to develop, operate, manage, market, distribute and license
text, audio and video music, music-related and music-themed services online and
engage in reasonably related activities, including e-commerce applications and
consumer oriented commercial transactions (the "Business"). Pursuant to the
Organization Agreement, (i) the Company caused its subsidiaries SonicNet, Inc.
and The Box Worldwide Inc. to contribute substantially all of their respective
assets and businesses, and the stock of their respective subsidiaries which
exclusively conduct their respective international businesses, subject to
certain exceptions, to separate limited liability companies, the membership
interests in which were then contributed to Music.co and (ii) MTVN contributed
to Music.co the assets and businesses owned or controlled by it that constituted
all of its current or planned assets and businesses engaged, or to be engaged,
exclusively in the Business, including those assets and businesses used
exclusively in connection with the MTV.com, VH1.com and Imagine Radio
businesses, and all wholly owned international assets and businesses engaged
exclusively in the Business, subject to certain exceptions. For their respective
contributions, the Company received an aggregate 10% limited partnership
interest in Music.co and MTVN received an aggregate 90% general and limited
partnership interest in Music.co.

                                       2
<PAGE>

     Under the terms of the Music.co Partnership Agreement, the Company is
entitled to designate one member of the management committee of Music.co and
will have certain approval rights with respect to enumerated actions by
Music.co, subject to certain conditions. MTVN is entitled to appoint a majority
of the members of the management committee of Music.co.

     In the Parent Agreement and Guaranty the Company and Liberty have each
agreed not to, and to cause their respective controlled affiliates not to, own,
operate or make an investment in the Business (other than the investment in
Music.co) or in the business of operating any cable or satellite audio/video
television services, digital or analog, that principally or in large part are
devoted to music-related or music-themed programming (the "Television
Business"), in each case subject to certain exceptions, until the first to occur
of (a) three years (in the case of the restrictions relating to the Business) or
five years (in the case of the restrictions relating to the Television Business)
after the Closing and (b) such date as MTVN ceases to own the largest percentage
of the equity in Music.co and to have the right to designate the most members of
the management committee or board of directors of Music.co.

     In addition, pursuant to the Parent Agreement and Guaranty MTVN has agreed
that, subject to certain exceptions, if MTVN, directly or through a controlled
affiliate, acquires, makes an investment in or otherwise operates the Business
other than through Music.co at any time during the

                                       3
<PAGE>

five-year period following the Closing, it will provide the Company the right to
purchase a pro-rata interest in such business or assets so long as the Minimum
Percentage Condition (as defined) is satisfied. MTVN has also agreed, for the
same period, not to promote the Business as owned or operated by any of its
affiliates (other than Music.co) on any of its cable television services except
on commercial terms.

     Under the Music.co Partnership Agreement and the Parent Agreement and
Guaranty, the parties have also agreed to certain restrictions on their ability
to transfer their respective partnership interests in Music.co, first offer
rights of MTVN with respect to certain proposed transfers by the Company of its
interest; pro rata drag along rights of MTVN and pro rata tag along rights of
the Company with respect to  proposed transfers by MTVN of a controlling
interest in Music.co; certain preemptive rights of the Company, and certain
registration rights of the Company.  In addition, during a specified period
following the fifth anniversary of the Closing, the Company may require MTVN to
purchase all of its interest in Music.co, and during a specified period
following the sixth anniversary of the Closing, MTVN may require the Company to
sell the Company's interest in Music.co, in each case at a price based on the
public trading price of Music.co's stock if it is then a public company or on
the appraised fair market value of Music.co if it is not then publicly held.

     The Organization Agreement, Music.co Partnership Agreement and Parent
Agreement and Guaranty also contain other terms and conditions customary to
transactions of this kind.  In connection with the formation of Music.co,
Music.co, MTVN and certain of their respective affiliates entered

                                       4
<PAGE>

into the license agreement, promotion agreement and services agreements
contemplated by the May 19 letter agreement.

the Music.co Partnership Agreement is included as Exhibit 2.2, a copy of the
Parent Agreement and Guaranty is included as Exhibit 2.3, and a copy of the

Partnership is included as Exhibit 99.1 to this Form 8-K. Such documents,
together with the Prior 8-K, are hereby incorporated by reference into this
Item 2, and the foregoing descriptions of such agreements and documents are
qualified in their entirety by reference to such Exhibits and the Prior 8-K.

         UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

The following unaudited proforma condensed combined financial information has
been prepared to give proforma effect to the investment in Music.co.  The
investment in Music.co has been accounted for as a sale between unaffiliated
parties.

The unaudited proforma condensed combined balance sheet as of March 31, 1999 and
the unaudited proforma condensed combined statements of operations for the three
months ended March 31, 1999 and for the year ended December 31, 1998 give
proforma effect to the exchange of SonicNet and The Box, for a 10% ownership
interest in Music.co and the related tax effects of the investment.  The
unaudited proforma information gives effect to the transactions as if they had
occurred as of March 31, 1999, for the unaudited condensed combined balance
sheet and as of January 1, 1998 for the unaudited condensed combined statements
of operations.

The unaudited proforma condensed combined balance sheet and condensed combined
statement of operations do not purport to represent what TCI Music's results of
operations would have actually been if the foregoing transaction had, in fact
occurred on January 1, 1998.  The unaudited proforma condensed combined balance
sheet and condensed combined statement of operations should be read in
conjunction with the historical audited consolidated financial statements of TCI
Music.

Exchanged assets
- - ----------------
a    Amounts reflect the carrying values of the assets and liabilities of
     SonicNet and The Box (contributed by TCI Music to Music.co in exchange for
     a 10% ownership interest in Music.co.) as if such assets were
     deconsolidated from TCI Music on March 31, 1999.

Investment in Music.co
- - ----------------------
b    TCI Music will record its 10% ownership interest in Music.co at the
     ascribed fair value of $150 million (such ascribed fair value has been
     estimated by management and is subject to final valuation procedures). TCI
     Music will account for its investment in Music.co under the cost method.
     The contribution of SonicNet and The Box in exchange for the 10% interest
     in Music.co will be accounted for as a sale for financial reporting
     purposes and accordingly, it is expected that TCI Music will recognize a
     gain on the transaction. An illustration of the gain computation, on a
     proforma basis at March 31, 1999 is as follows:

          (g)  With respect to any director, employee, consultant, agent or
independent contractor of any Tune Subsidiary or Box Italy who is not a SonicNet
LLC Employee or a Box-MTVN Employee, and whose employment or services cannot be
completely terminated prior to the consummation of the Closing due to any
applicable Laws, the Partnership or MTVN, as applicable, shall assist in the

reasonable efforts to obtain rebates of all launch fees paid to any cable system

               -------------------------
rights under the Access Provisions to TCI Music in connection with certain
recently-announced proposed transactions between Liberty and TCI Music, then to
the extent that AT&T provides or otherwise enables the functionalities necessary
to provide interactive television applications over the AT&T Systems, and TCI
Music decides to provide an interactive music and music related transaction
channel (an "Interactive Music Channel"), TCI Music agrees to offer to the
Partnership the opportunity to enter into a joint venture with TCI Music to
provide such channel, the terms and conditions of such joint venture to be
subject to the terms of the Access Provisions, as they may be amended, and upon
the formation of such joint venture, the Partnership agrees to offer (which
offer shall remain outstanding for 30 days) to license to such joint venture the
rights to the database being licensed pursuant to the Database License Agreement
on terms no less favorable than those of the Database License Agreement.
Formation of such a joint venture will also be subject to TCI Music and the
Partnership's formulation of a mutually acceptable business plan and to the
execution and delivery of reasonably acceptable definitive documentation
regarding the joint venture.  In the event the Partnership and TCI Music do not
enter into such joint venture, neither such Person will have any further
obligation under this Section 3.3, but such failure shall not affect any of TCI
Music's obligations under Section 4.2 of the Parent Agreement.  In the event
that Liberty does not assign its rights under the Access Provisions as they may
be amended to TCI Music, Liberty will not be obligated by the terms of this
Section

without limitation, its obligations under Section 6 thereof; and

               (iv)  refrain from taking any action following the Closing, and

shall not create, incur, permit to exist or have outstanding any Lien on any of
the SonicNet Trademarks. In the event that the Telstra Agreement is terminated
prior to its scheduled expiration, not renewed by Telstra, or if renewed by

forth herein regarding the SonicNet LLC Assets which constitute Intellectual
Property, pursuant to an instrument of conveyance in form and substance
reasonably satisfactory to SonicNet LLC and SonicNet, and thereafter shall be
owned exclusively by SonicNet LLC.

          (c)  Upon a breach of the Telstra Agreement by any party thereto other
than SonicNet (which breach gives SonicNet the right to terminate the Telstra
Agreement), SonicNet shall immediately, to the extent provided for in the
Telstra Agreement, terminate such Agreement.

expenditures of Box Holland in accordance with the projected Business Plan for
Box Holland (1998-2001) as previously furnished to MTVN, but in no event more
than $1.3 million in the aggregate; provided, however, that prior to any such
                                    --------  -------
advance, Box certifies that the conditions to such advance have been satisfied.
If the interest in Box Holland of Box's applicable subsidiary is sold or
otherwise disposed of, Box will repay such advances out of, but only to the
extent of, the cash proceeds actually received by it or its Affiliates from such
sale, and otherwise shall have no obligation or liability with respect to such
advances. To the extent such cash proceeds are sufficient therefor, the amount
to be repaid will include simple interest of 6% per annum.

breach of, or failure to perform or comply with, any covenant or agreement set
forth in this Agreement or in any Contribution Agreement or in any certificate

                      ---------------------    ---
the applicable Person or Persons required hereunder to provide indemnification
pursuant to this Article 7.  The indemnified party's failure to so notify the

indemnifying party of any such matter shall not release the indemnifying party,
in whole or in part, from its obligations to indemnify under this Article 7,

except to the extent the indemnified party's failure to so notify actually
prejudices the indemnifying party's ability to defend such action.  If the facts
giving rise to such indemnification shall involve any actual or threatened claim
or demand by or against a third party, the indemnifying party shall be entitled
to control the defense or prosecution of such claim or demand in the name of the
indemnified party, with counsel satisfactory to the indemnified party, if (x) it
notifies the indemnified party in writing of its intention to do so within 20
days of its receipt of such notice, without prejudice, however, to the right of
the indemnified party to participate therein through counsel of its own
choosing, which participation shall be at the indemnified party's expense unless
(i) the indemnified party shall have been advised by its counsel that use of the
same counsel to represent both the indemnifying party and the indemnified party
would present a conflict of interest (which shall be deemed to include any case
where there may be a legal defense or claim available to the indemnified party
which is different from or additional to those available to the indemnifying
party) or (ii) the indemnifying party shall fail to defend or prosecute in good
faith such claim or demand within a reasonable time, in

which case the reasonable fees of counsel for the indemnified party shall be for
the account of indemnifying party and the indemnifying party shall not have the
right to direct the defense of such action on behalf of the indemnified party,
and (y) it agrees to accept full responsibility indemnify and hold harmless the
indemnified party in accordance herewith in respect of the claim or demand.
Whether or not the indemnifying party chooses to defend or prosecute such claim,
the Partnership and the parties hereto shall cooperate in the prosecution or
defense of such claim and shall furnish such records, information and testimony
and attend such conferences, discovery proceedings, hearings, trials and appeals
as may reasonably be requested in connection therewith. The indemnifying party
shall not settle or permit the settlement of any such third party claim or
action in which any relief other than the payment of money damages is sought
against the indemnified party without the prior written consent of the
indemnified party. The indemnified party shall not settle or permit the
settlement of any claim or action for which it is entitled to indemnification
without the prior written consent of the indemnifying party, unless the
indemnifying party shall have failed to assume the defense thereof after the
notice referred to in the first sentence of this Section 7.8, and in the manner
                                                 -----------
provided above.

          7.9. Subrogation.  In the event of any indemnification made pursuant
               -----------
to a third party claim, the indemnifying party shall be subrogated to the extent
of such payment to all of the rights of recovery of the indemnified party, who
shall execute all papers required and shall do everything that may be necessary
to secure such rights, including the execution of such documents necessary to
enable the indemnifying party effectively to bring suit to enforce such rights.

          8.7. No Presumption. This Agreement shall be construed without
               --------------
regard to any presumption or rule requiring construction or interpretation

          8.8. Binding on Viacom.  The parties acknowledge that MTVN is a
               -----------------
division of Viacom and that, consequently, Viacom is obligated to perform the

parties agree that the representations and warranties set forth in Sections
4.1(a), 4.2(a), 4.2(b), 4.3 and 4.7, insofar as they purport to relate to MTVN,

Entity may assign its rights and obligations under this Agreement to one or more
Affiliates of MTVN which is directly or indirectly wholly-owned (and including
for this purpose Imagine) by Viacom, Inc.; provided that, in connection with any
                                           --------
such assignment, the applicable MTVN Entity executes and delivers to TCI Music
an instrument, in form and substance reasonably satisfactory to TCI Music, by
which such MTVN Entity guarantees the performance of any such assignee's
obligations hereunder.  TCI Music may assign any or all of its rights and
obligations under this Agreement to any of its wholly-owned subsidiaries;
provided that, in connection with any such assignment, TCI Music executes and
- - --------
delivers to MTVN an instrument, in form and substance reasonably satisfactory to
MTVN, by which TCI Music guarantees the performance of any such assignee's
obligations hereunder.  No party to this Agreement may assign any of its rights
or obligations under this Agreement except as specifically provided in this
Section 8.9.  The terms of this Agreement shall be binding upon and inure to the
benefit of the parties hereto and their respective successors and permitted
assigns.  Any assignment of rights hereunder in violation hereof shall be null
and void ab initio.  Nothing in this Agreement, whether express or implied,
         -- ------
shall be construed to give any Person (other than the parties hereto and their
successors and permitted assigns) any legal or equitable right, remedy or claim
under or in respect of this Agreement or any covenants, conditions or provisions
contained herein.  None of the provisions of this Agreement shall be for the
benefit of or enforceable by any third party except the provisions of Article 7
shall be enforceable by all Indemnified Parties.

          8.10.  Waivers; Remedies.  The observance of any term of this
                 -----------------

term, but any such waiver shall be effective only if

in a writing signed by the party or parties against which such waiver is to be
asserted and only in the specific instance and for the specific purpose for
which given. Except as otherwise provided herein, no failure or delay of any
party in exercising any power or right under this Agreement shall operate as a
waiver thereof, nor shall any single or partial exercise of any such right or
power, or any abandonment or discontinuance of steps to enforce such right or
power, preclude any other or further exercise thereof or the exercise of any
other right or power.

          8.11.  Further Assurances.  Upon reasonable request from time to time,
                 ------------------
each of MTVN and TCI Music and their respective Controlled Affiliates shall
execute and deliver all documents and instruments and do all other acts that may
be reasonably necessary or desirable to carry out the intent and purposes of
this Agreement and give effect to the exercise by a party of its rights
hereunder.

          8.12.  Public Announcements.  No party shall make or shall permit any
                 --------------------
of its Affiliates to make any public announcement about the transactions
contemplated by this Agreement without the prior written consent of the other
parties hereto, which consent shall not be unreasonably withheld or delayed.
Notwithstanding any other provision contained herein, any party or Affiliate of
such party may at any time make announcements which are required by applicable
law or the rules of any national stock exchange or stock association so long as
the party or Affiliate so required to make the announcement, promptly upon
learning of such requirement, notifies the other parties of such requirement and
discusses with the other parties in good faith the exact wording of any such
announcement.

          8.13.  Costs and Expenses.  Each party shall be solely responsible for
                 ------------------

court sitting in the County of New York or any federal court of the United
States of America sitting in the Southern District of New York, and any

recognition or enforcement of any judgment relating hereto.  Each party hereby
irrevocably and unconditionally agrees that any suit, action or proceeding
against it by any other party to this Agreement with respect to this Agreement
or any Contribution Agreement shall be instituted only in any New York State
court sitting in the County of New York or any federal court sitting in the
Southern District of New York, as the party instituting such suit, action or

suit on the judgment or in any other manner provided by law.

court from any such court. Each party hereby irrevocably waives, to the fullest

court does not have jurisdiction over such party. Each party hereby irrevocably
waives the right to a jury trial in any suit, action or proceeding arising out
of or related to this Agreement or any Contribution Agreement.

          (c)    Each party hereby irrevocably and unconditionally consents to

     Section 2.07.    Purpose.  Subject to, and upon the terms and conditions

manage, market, promote, distribute and license text, audio and/or video music,
music-related and/or music-themed services online and (b) engage in activities
reasonably related thereto, including e-commerce applications and consumer
oriented commercial transactions related thereto.  Services that are intended
principally to be delivered to internet browsers or software with browser
functionality, even if such browsers or browser functionality are operating
through a set-top box or a television set and/or are used to deliver video clips
or video programs, shall be included in the Business.  The terms "browsers" and
"browser functionality" for purposes of the foregoing shall refer to software
consisting of or containing a graphical user interface which provides the
capability for the user to exercise substantial control over the selection,
timing, sequence and configuration of content being viewed, when such software
is used to view content that has been specifically adapted to be subject to such
user controls, and is not primarily intended to be viewed in a linear,
sequential manner.  Notwithstanding anything to the contrary contained herein,
businesses that are substantially similar to the businesses traditionally
conducted by television, cable and satellite television program services, and
businesses presently described as "near video on demand" and "video on demand"
shall not be considered to be within the Business.  The Partnership shall have
all the powers now or hereafter conferred by the laws of the State of Delaware
on limited

                                     -14-

partnerships formed under the Act and, subject to the limitations of this
Agreement, may do any and all lawful acts or things that are necessary,
appropriate, incidental or convenient for the furtherance and accomplishment of
the purposes and businesses of the Partnership. Notwithstanding the foregoing,

deems appropriate with respect to any assets relating to the programming service
owned by Box or Box LLC and any FCC Licenses relating thereto.

     Section 2.08.    Property Ownership.  Subject to Section 2.02 and except as
                      ------------------              ------------
otherwise expressly provided herein, all assets and property, whether real,
personal or mixed, tangible or intangible, including contractual rights, owned
or possessed by the Partnership shall be held or possessed in the name of the
Partnership; all such assets, property and rights shall be deemed to be owned or
possessed by the Partnership as an entity, and none of the Partners individually
shall have any separate ownership in such assets, property or rights.  Each
Partner's Partnership Interest is personal property for all purposes.

                                  ARTICLE III

                              PARTNERSHIP CAPITAL
                              -------------------

     Section 3.01.    Percentage Interests.
                      --------------------

            (a)       The "Percentage Interest" of each Partner as of any date
shall be equal to the percentage obtained by dividing (i) the aggregate amount
of all Capital Contributions made by such Partner in cash and the Agreed Value
of all Capital Contributions made by such Partner other than in cash as of such
date by (ii) the aggregate amount of all Capital Contributions made by all the
Partners in cash and the Agreed Value of all Capital Contributions made by all
the Partners other than in cash as of such date. The Percentage Interest of a
Stockholder Group shall be the percentage equal to the sum of the Percentage
Interests of all the Partners in such Stockholder Group. The initial Percentage
Interest of each Partner as of the date of this Agreement is as follows:

     VLLC ........................................................     1%
     interest as the General Partner

          ........................................................    69%
     interest as a Limited Partner

     Imagine .....................................................    20%
     interest as a Limited Partner

     SonicNet ....................................................  8.75%
     interest as a Limited Partner

     Box .........................................................  1.25%
     interest as a Limited Partner

            (b)       For purposes of this Agreement, (i) VLLC is treated as
though it holds a single Partnership Interest, even though it holds a portion of
its Partnership Interest as a General Partner, (ii) the combined Partnership
Interest of VLLC and Imagine and their Permitted Transferees may be referred to
as the "MTVNS Partnership Interest" and (iii) the combined Partnership Interest
of SonicNet and Box and their Permitted Transferees may be referred to as

                                     -15-
<PAGE>

the "Tune Partnership Interest." Whenever this Agreement requires that notice be
given to, or any rights be given to, Tune or MTVNS, they shall be given to both
SonicNet and Box and their Permitted Transferees or to both VLLC and Imagine and
their Permitted Transferees, respectively. Whenever this Agreement permits
rights to be exercised by Tune, on the one hand, or MTVNS, on the other hand,
SonicNet or Box (or both) and their Permitted Transferees, on the one hand, or
VLLC or Imagine (or both) and their Permitted Transferees, on the other hand,
may exercise such rights, respectively. Notwithstanding anything in this
Agreement to the contrary, the Partners intend that MTVNS shall hold one
ninetieth (1/90) of its Partnership Interest as a General Partner and eighty-
nine ninetieths (89/90) of its Partnership Interest as a Limited Partner.
Accordingly, the amount of any Capital Contributions made by MTVNS pursuant to
Article III and any allocations and distributions to MTVNS pursuant to Article
- - -----------                                                            -------
IV or Article V shall, except as otherwise provided therein, be allocated one
- - --    ---------
ninetieth (1/90) to the Partnership Interest held by MTVNS as a General Partner
and eighty-nine ninetieths (89/90) to the Partnership Interest held by MTVNS as
a Limited Partner. In the event that the Partnership Interest of a Partner is
otherwise increased or decreased pursuant to this Agreement, the amount of the
increase or decrease, as the case may be, shall be allocated in accordance with
the intent of this paragraph.

     Section 3.02.    Contribution of Partnership Assets.  On the Closing Date,
                      ----------------------------------
each Partner shall transfer to the Partnership those assets specified in the
Contribution Agreement to which such Partner is a party, and the Agreed Value of
such assets shall be as set forth on Schedule 1; such assets shall be
                                     ----------
transferred to the Partnership in accordance with the applicable Contribution
Agreement.  As a result of such transfer, the Capital Accounts of each Partner
will be credited with an amount equal to the Agreed Value of the assets
contributed by such Partner.  Prior to the Closing Date, each Partner has made
Pre-Closing Capital Contributions in an amount equal to the amount set forth
opposite such Partner's name in Schedule 1, and the Capital Accounts will be
                                ----------
credited with the amounts of such Capital Contributions.  At the Closing each
Partner shall make a Closing Capital Contribution in the amount set forth
opposite its name on Schedule 1, and the Capital Accounts will be credited with
                     ----------
the amounts of such Capital Contributions.

     Section 3.03.    Additional Capital Contributions.
                      --------------------------------

               (a)    Each Budget shall set forth any Capital Contributions
which are expected to be necessary to fund Partnership Costs during the Fiscal
Year covered by such Budget, which Capital Contributions shall be designated as
Required Contributions and/or Non-Required Contributions, depending upon whether
such Partner has made Capital Contributions in excess of its Maximum Capital
Contribution Obligations. All Capital Contributions shall be deemed to be
Required Capital Contributions until such time as the applicable Partner has
contributed an amount in cash or property (excluding its Pre-Closing Capital
Contribution, Closing Capital Contribution, and contributions under the
applicable Contribution Agreement) having an Agreed Value equal to its Maximum
Capital Contribution Obligation, and thereafter all such Capital Contributions
with respect to such Partner will be Non-Required Capital Contributions. Each
Partner shall make all such Capital Contributions within 30 days of the date
provided for in the Budget, so long as a Capital Call is given therefor, except
that either Partner may elect not to make all or any portion of a Non-Required
Contribution. All such Capital Contributions shall be made pro-rata in
accordance with the Partners' Percentage Interests,

                                     -16-
<PAGE>

except to the extent a Partner elects not to make all or any portion of a Non-
Required Contribution.

          (b)  Subject to the limitations of this Agreement, if the Management
Committee determines that additional Capital Contributions are necessary from
time to time to fund Partnership Costs in excess of that provided for in any
then relevant Budget or pursuant to any prior Capital Call, the Management
Committee shall cause the Chief Executive Officer to deliver a Capital Call to
each Partner.  Subject to the election of any Partner not to make all or any
portion of a Non-Required Contribution, the Partners shall make all additional
Capital Contributions pro rata in proportion to their Percentage Interests on
the Payment Date specified in the Capital Call requesting such additional
Capital Contributions; provided, however, that no Partner shall be required to
                       --------  -------
make an additional Capital Contribution in an amount in excess of the amount
which, when taken together with the aggregate amount of all previous Capital
Contributions (excluding, without duplication, those made pursuant to Section
                                                                      -------
3.02 and the Pre-Closing and Closing Capital Contribution) made by such Partner,
- - ----
exceeds such Partner's Maximum Capital Contribution Obligation.

          (c)  In the event that Tune elects not to make any portion of a
Capital Contribution or fails to do so on or before the relevant Payment Date,
MTVNS and/or any other Person(s) designated by MTVNS may make such portion of
Capital Contribution (or any portion thereof) and, thereafter the Percentage
Interests of each Partner shall be adjusted so that they are in proportion to
the relative cumulative Capital Contributions by each Partner; provided,
                                                               --------
however, that no such additional Non-Required Capital Contribution shall be made
- - -------
if such additional Non-Required Capital Contribution and the related adjustment
to the Percentage Interests would, on a pro forma basis, cause the Percentage
Interest for the Tune Partnership Interest to be less than the lesser of (i) 5%
and (ii) the percentage equal to one-half of the excess of (x) ten percent over
(y) the Percentage Interest of any portion of the Tune Partnership Interest
Transferred to a Person other than a Permitted Transferee. In the event the
circumstances described in the proviso of the preceding sentence apply, MTVNS
and/or any other Person(s) designated by MTVNS may loan the Partnership the
amount of such Capital Contribution (or portion thereof), in which event such
loan(s) shall be subject to Section 3.05.
                            ------------

     Section 3.04.    Partnership Funds.  The funds of the Partnership shall be
                      -----------------
deposited in such bank accounts or invested in such investments as shall be
designated by the Management Committee.  Partnership funds shall not be
commingled with those of any other Person without the consent of the Management
Committee.  The Partnership shall not lend or advance funds to, or guarantee any
obligation of, a Partner or any Affiliate thereof without the prior written
consent of the Management Committee.

     Section 3.05.    Partner Loans; Other Borrowings.  Subject to any
                      -------------------------------
applicable approval required by Article VI, in order to satisfy the
                                ----------
Partnership's financial needs, the Partnership may, if so determined by the
Management Committee, (i) borrow from banks, lending institutions or other
unrelated third parties, and may pledge Partnership properties or the production
of income therefrom to secure and provide for the repayment of such loans and
(ii) borrow funds from any Partner or an Affiliate of a Partner on an unsecured
basis and on market terms.  Loans made by a Partner or an Affiliate of a Partner
(a "Partner Loan") shall be

                                     -17-
<PAGE>

evidenced by a promissory note of the Partnership on the terms and in the form
approved by the lending Partner and the Management Committee. Unless a Partner
declines to make such loan, Partner Loans shall be made pro rata in accordance
with the respective Percentage Interests of the Partners (or in such other
proportion as the Partners may agree). Partner Loans shall be repaid to the
Partners at such times as the Partnership has sufficient funds to permit such
repayment without jeopardizing the Partnership's ability to meet its other
obligations on a timely basis. Nothing contained in this Agreement or in any
promissory note issued by the Partnership hereunder shall require the
Partnership or any Partner to pay interest or any amount as a penalty at a rate
exceeding the maximum amount of interest permitted to be collected from time to
time under applicable usury laws. If the amount of interest or of such penalty
payable by the Partnership or any Partner on any date would exceed the maximum
permissible amount, it shall be automatically reduced to such amount, and
interest or the amount of the penalty for any subsequent period, to the extent
less than that permitted by applicable usury laws, shall, to that extent, be
increased by the amount of such reduction.

Partner having a negative Adjusted Capital Account balance.  The Partnership
shall pay in full all Partner Loans (in accordance with the order of payment
contemplated by Section 10.02(c)(iii)) prior to making any cash distributions to

the Partners.  Except as otherwise contemplated by Section 10.02 or Section

                    -----------------------
of this Agreement, if for any Fiscal Year there is a net decrease in Partnership
Minimum Gain, each Partner shall be specially allocated items of Partnership
income and gain for such year (and, if necessary, for succeeding years) in an
amount equal to such Partner's share of the net decrease in Partnership Minimum
Gain, determined in accordance with Regulations Section 1.704-2(g), except as
otherwise provided in Regulations Sections 1.704-2(f)(2), 1.704-2(f)(3), 1.704-
(2)(f)(4), and 1.704-2(f)(5). Allocations pursuant to the previous sentence
shall be made in proportion to the respective amounts required to be allocated
to each Partner pursuant thereto. The items to be so allocated shall be
determined in accordance with Regulations Section 1.704-2(f)(6). This Section
                                                                      -------
5.02(b) is intended to comply with the minimum gain chargeback requirement of
- - -------
Regulations Section 1.704-2(f) and shall be interpreted consistently therewith.

               (c)  Partner Minimum Gain Chargeback.  Notwithstanding any other
                    -------------------------------
provision of this Agreement, if during a Fiscal Year there is a net decrease in
Partner Nonrecourse Debt Minimum Gain, each Partner who has a share of that
Partner Nonrecourse Debt Minimum Gain (determined in accordance with Regulations
Section 1.704-2(i)(5)) as of the beginning of such year shall be specially
allocated items of Partnership income and gain for such year (and, if necessary,
for succeeding years) in an amount equal to such Partner's share of the net
decrease in Partner Nonrecourse Debt Minimum Gain, determined in accordance with
Regulations Section 1.704-2(i)(4) (and taking into account the exceptions
provided therein).  Allocations pursuant to the previous sentence shall be made
in proportion to the respective amounts required to be allocated to each Partner
pursuant thereto.  The items to be so allocated shall be determined in
accordance with Regulations Section 1.704-2(i)(4).  This Section 5.02(c) is
                                                         ---------------
intended to comply with the minimum gain chargeback requirement in Regulations
Section 1.704-2(i)(4) and shall be interpreted consistently therewith.

               (d)  Partner Nonrecourse Deductions.  Any Partner Nonrecourse
                    ------------------------------
Deductions for any Fiscal Year or other period shall be specially allocated to
the Partner who bears the economic risk of loss with respect to the Partner
Nonrecourse Debt to which such Partner Nonrecourse Deductions are attributable
in accordance with Regulations Section 1.704-

                                     -19-
<PAGE>

2(i). If more than one Partner bears the economic risk of loss with respect to
the Partner Nonrecourse Debt, then the Partner Nonrecourse Deductions
attributable to that Partner Nonrecourse Debt shall be allocated among the
Partners based upon the ratio in which they bear the economic risk of loss.

          (e)  Qualified Income Offset.  In the event that any Partner
               -----------------------
unexpectedly receives any adjustments, allocations or distributions described in
Regulations Section 1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5), or 1.704-
1(b)(2)(ii)(d)(6), items of Partnership income and gain shall be specifically
allocated to such Partner in an amount and manner sufficient to eliminate, to
the extent required by the Regulations promulgated under Section 704(b) of the
Code, the deficit balance, if any, in its Adjusted Capital Account created by
such adjustments, allocations or distributions as quickly as possible.  This
provision is intended to be a "qualified income offset" described in Regulations
Section 1.704-1(b)(2)(ii)(d) and is to be interpreted in a manner consistent
therewith.

          (f)  Offsetting Allocations. In the event that any item of Partnership
               ----------------------
income, gain, loss, deduction or Section 705(a)(2)(B) Expenditure is allocated
pursuant to Section 5.02(b), (c), (d) or (e), subsequent items of Partnership
            --------------------------------
income, gain, loss, deduction or Section 705(a)(2)(B) Expenditure (as determined
for purposes of computing Net Income or Net Loss) shall, to the extent
consistent with Sections 5.02(b), (c), (d) and (e),  be allocated among the
                ----------------------------------
Partners so as to eliminate as quickly as possible on a proportionate basis,
with respect to each Partner, any disparity between (i) the sum of (x) such
Partner's Capital Account balance and (y) such Partner's share of Partnership
Minimum Gain and Partner Nonrecourse Debt Minimum Gain determined in accordance
with Regulations Section 1.704-2(g) and (i)(5) and (ii) the Capital Account
which such Partner would have had if all Partnership Minimum Gain and Partner
Nonrecourse Debt Minimum Gain had been realized and all allocations of Net
Income and Net Loss had been made pursuant to Section 5.02(a) (without giving
                                              ---------------
effect to the reference therein to Section 5.02 (b), (c), (d), (e) and (f)).
                                   ---------------------------------------

          (g)  Reallocations.  Notwithstanding the foregoing provisions, to the
               -------------
extent that any item of income, gain, deduction, or loss of any Partner (or any
Affiliate thereof) is required to be reallocated to the Partnership pursuant to
Code Section 482 or otherwise, or any item of income, gain, deduction or loss is
imputed to the Partnership as a result of a transaction between the Partnership
and any Partner (or any Affiliate thereof), such item shall be allocated in its
entirety to such Partner.

          (h)  IPO.  Notwithstanding the foregoing provisions, in the event that
               ---
the Partnership is liquidated in conjunction with an IPO as described in Section
1.2 of the Parent Agreement and Guaranty and the number of Shares to be
distributed to the Tune Partners is increased pursuant to Section 1.2 of the
Parent Agreement and Guaranty, Net Income and Net Loss for the Fiscal Year in
which the liquidation occurs shall be allocated in such a manner that the
Capital Account balances of the Partners immediately prior to the distribution
of Shares in such liquidation (but after taking into account distribution of any
other assets and recognition of gain or loss with respect to the Shares pursuant
to clause (C) of the proviso in the definition of Net Income or Net Loss) shall
be in proportion to the number of Shares to be distributed to the Partners
pursuant to Section 1.2 of the Parent Agreement and Guaranty.

     Section 5.03.    Allocations for Federal Income Tax Purposes.  The
                      -------------------------------------------
Partnership's ordinary income and losses, capital gains and losses and other tax
items as determined for federal income tax purposes shall be allocated to the
Partners in the same manner as the corresponding "book" items are allocated
pursuant to Section 5.02.  Notwithstanding the foregoing sentence, federal
            ------------
income tax items relating to Section 704(c) Property shall be allocated among
the Partners in accordance with Section 704(c) of the Code or Regulations
Section 1.704-1(b)(2)(iv)(f), as applicable, using the remedial method of
regulations Section 1.704-3(d) to take into account the difference between the
fair market value and the tax basis of such Section 704(c) Property as of the
date of its contribution to the Partnership or revaluation pursuant to Section
                                                                       -------
5.01(b).  Credits shall be allocated in accordance with the allocation of the
- - -------
deduction for the Partnership expenditure which gave rise to the credit.  Items
described in this Section 5.03 shall neither be credited nor charged to the
                  ------------
Capital Accounts of the Partners.

     Section 5.04.    Prorated Allocations.  In the event of a Transfer of any
                      --------------------
Partnership Interest, regardless of whether the transferee is already a Partner
or becomes an additional, substitute or successor Partner, all items of income,
gain, loss and deduction attributable to such Partnership Interest for the
Fiscal Year in which the Transfer occurs shall be allocated between the
transferor and the transferee on the basis of the ownership of such Partnership
Interest during such Fiscal Year.  Subject to Section 706 of the Code, such
allocation shall be made either by prorating items of income, gain, loss and
deduction for such year based upon the number of days that such Partnership
Interest was owned by the transferor and the transferee, respectively, or in
accordance with a closing of the books on an interim basis on the date on which
the Transfer occurred, as determined by the Management Committee.

     Section 5.05.    Taxation.
                      --------

               (a)    The Partners intend that the Partnership shall be treated
as a "partnership" for federal, state and local income and franchise tax
purposes, and each Partner agrees to take all actions reasonably necessary to
achieve such intent.

               (b)   In the event of a Transfer of all or part of a Partner's
Partnership Interest, the Chief Executive Officer shall at the request of the
transferee cause the Partnership to elect, pursuant to Section 754 of the Code,
to adjust the basis of the Partnership's property; provided, however, that the
                                                   --------  -------
tax items attributable to any such basis adjustment shall be allocated solely to
such transferee and such transferee shall reimburse the Partnership promptly for
all costs associated with such basis adjustment, including bookkeeping,
appraisal and other similar costs.

               (c)   Except as otherwise expressly provided herein, all other
elections required or permitted to be made by the Partnership under the Code (or
applicable state or local tax law) shall be made in such manner as may be
determined by the Chief Executive Officer to be in the best interests of the
Partners as a group.

     Section 5.06.   Fiscal Year.  The fiscal year of the Partnership ("Fiscal
                     -----------
Year") for tax and accounting purposes shall end on the last day of December of
each year.

such interest shall be accrued or paid.

                         MANAGEMENT OF THE PARTNERSHIP
                         -----------------------------

     Section 6.01.    Management Committee.
                      --------------------

          (a)  There is hereby established a Management Committee for the
Partnership (the "Management Committee").  Prior to the initial closing of the
IPO, the Management Committee shall consist of nine Representatives, (i) with
one Representative designated by Tune so long as (x) the Percentage Interest of
the Tune Partnership Interest (including Partnership Interests held by the Tune
Stockholder Group) is at least 5% (excluding any Partnership Interests issued or
granted (including Partnership Interests issued upon exercise of any option,
warrant or other right to acquire Partnership Interests) in any transaction or
transactions with respect to which Tune has no preemptive rights pursuant to
Section 12.02 hereof), (y) neither Tune, TCI Music nor any of their Controlled
- - -------------
Affiliates is in material default under this Agreement or any of the Additional
Agreements to which it is a party and (z) none of the Tune Stockholder Group has
Transferred any portion of its Partnership Interest to any Person that is not a
Permitted Transferee (the satisfaction of the foregoing clauses (x), (y) and
(z), the "Tune Minimum Condition"), and (ii) with the remaining Representatives
designated by MTVNS. One Representative designated by MTVNS shall be chairperson
of the Management Committee.  The Persons selected to be the initial
Representatives of each Partner, effective as of the date hereof are listed on
Schedule 2 hereto. The Representatives of each Partner shall at all times be
- - ----------
executive officers or other full-time employees of either such Partner or an
Affiliate of such Partner.  Each Representative shall have one vote on all
matters, which vote may be cast in person or by proxy.

          (b)  Any Partner may, at any time, by written notice to the other
Partner, remove any or all of its Representatives, with or without cause, and
appoint substitute Representative(s) to serve in their stead. Each Partner shall
be entitled to name an alternate Representative to serve in the place of any
Representative appointed by such Partner should any such Representative not be
able to attend a meeting or meetings. Each Partner shall bear the costs incurred
by each Representative or alternate designated by it to serve on the Management
Committee, and no Representative or alternate shall be entitled to compensation
from the Partnership for serving in such capacity.

          (c)  In the event any Representative dies or is unwilling or unable to
serve as such or is removed from office by the Partner that designated him or
her, such Partner shall promptly designate a successor to such Representative.
Such successor shall be appointed as soon as possible, but in no event later
than 30 days after the day such vacancy first occurs.

          (d)  The written notice of a Partner's appointment of a Representative
or alternate shall in each case set forth such Representative's or alternate's
business and residence addresses and business telephone number.  Each Partner
shall promptly give written

                                     -22-
<PAGE>

notice to the other Partner of any change in the business or residence address
or business telephone number of any of its Representatives.

          (e)  Each Partner shall cause its Representative(s) on the Management
Committee to comply with the terms of this Agreement.  In the absence of prior
written notice to the contrary, any action taken by a Representative shall, so
far as the other Partner is concerned, be deemed to have been duly authorized by
the Partner that appointed such Representative.

     Section 6.02.    Meetings of the Management Committee.
                      ------------------------------------

          (a)  The initial meeting of the Management Committee shall take place
on such date and at such time and place as the Partners agree. The Management
Committee shall hold a regular meeting in the fourth quarter of each year to
approve the Proposed Budgets and Proposed Business Plans and otherwise at the
call of the Chief Executive Officer or any Representative. The Management
Committee may meet by means of telephone, conference telephone or similar
communications equipment. Unless a longer notice period is established by the
Management Committee, at least seven Business Days prior notice of any regular
meeting and at least three Business Days' prior notice of a special meeting
shall be given. Any Representative of a Partner may waive notice to such Partner
of any meeting in writing before, at or after such meeting. The attendance of
any Representative of a Partner at a meeting shall constitute a waiver by such
Partner of notice of such meeting, except when such Representative attends a
meeting for the express purpose of objecting to the transaction of any business
because the meeting was not properly called. Except as otherwise determined by
the Management Committee, all regular meetings of the Management Committee shall
be held at the principal office of the Partnership.

          (b)  At any meeting of the Management Committee, the presence or
participation of at least one Representative for each Partner, in person or by
proxy, shall constitute a quorum for the taking of any action, provided that (i)
                                                               --------
all Partners have received prior written notice of such meeting or have waived
such notice as provided in Section 6.02(a); and (ii) no Representative can
                           ---------------
refrain from attending a meeting of the Management Committee in order to deny
the establishment of a quorum.  All actions required or permitted to be taken by
the Management Committee may be taken, in lieu of a meeting, by written consent
(which may be executed in counterparts) of the Representatives of the Partners;
copies of all written consents shall be provided to all Representatives.  All
actions to be taken by the Management Committee shall be by the votes (or
written consent) required in Section 6.05 or 6.06.  Each Representative entitled
                             --------------------
to vote at a meeting of the Management Committee may authorize another Person to
act for him by proxy, provided that such proxy must be signed by the
                      --------
Representative and shall be revocable by such Representative at any time prior
to such meeting.  Minutes of each meeting of the Management Committee shall be
prepared and circulated to the Representatives.  Written consents to any action
taken by the Management Committee shall be filed with the minutes.

     Section 6.03.    Officers of the Partnership.  The Partnership shall have
                      ---------------------------
such officers (the "Officers") as the Management Committee may determine from
time to time, it being agreed by the Partners that MTVNS will appoint the Chief
Executive Officer, subject to consultation with Tune so long as Tune is entitled
to designate a Representative on the Management Committee pursuant to Section
                                                                      -------

<PAGE>

Fred Seibert. The Chief Executive Officer shall be responsible for and exercise
control over the Partnership, except for those matters referred to as Committee
Decisions or Extraordinary Decisions. Except as provided above or as otherwise
determined by the Management Committee, the Chief Executive Officer shall (x)
have such powers as are usually exercised by a comparably designated officer of
a Delaware corporation and (y) have the power to bind the Partnership through
the exercise of such powers to the extent consistent with the terms of this
Agreement. The Chief Executive Officer (or his or her designee) shall attend the
meetings of the Management Committee unless otherwise requested by the
Management Committee and shall provide such reports with respect to the business
of the Partnership as may be requested by the Management Committee. The Chief
Executive Officer may be removed with or without cause, subject, however, to
obligations under any employment agreement with the Chief Executive Officer, by
vote of a majority of the Management Committee.

     Section 6.04.    Budget and Business Plan.
                      ------------------------

          (a)  The Initial Budget and Initial Business Plan are attached hereto
as Schedules 3 and 4, respectively.  The Initial Budget includes an income
   -----------------
statement prepared on an accrual basis which shall generally detail the revenues
and expenses projected for the Partnership's Business through the end of 1999
and a cash flow statement which shall generally detail the receipts and
disbursements projected for the Partnership's business through the end of 1999
and the amount of any corresponding cash deficiency or surplus, together with
any contemplated additional Capital Contributions or contemplated borrowings of
the Partnership.

          (b)  The Chief Executive Officer shall submit annually to the
Management Committee no later than November 1, commencing November 1, 1999 (i) a
proposed Budget (each a "Proposed Budget"), which shall include any anticipated
Capital Calls for the forthcoming Fiscal Year in substantially the same detail
as the Initial Budget and (ii) a proposed Business Plan (a "Proposed Business
Plan") for the Fiscal Year covered by the Proposed Budget or a longer period.
Such Proposed Budget shall be prepared on a basis consistent with the Initial
Budget and, when available, the Partnership's audited financial statements. If
any Proposed Budget, Proposed Business Plan, Initial Budget or Initial Business
Plan, as the case may be, is approved by the Management Committee, then such
Proposed Budget, Proposed Business Plan, Initial Budget or Initial Business
Plan, as the case may be, shall be considered approved and shall constitute the
"Budget" or the "Business Plan," as the case may be, for all purposes of this
Agreement and shall supersede any previously approved Budget or Business Plan,
as the case may be. If a Proposed Budget, Proposed Business Plan, Initial Budget
or Initial Business Plan, as the case may be, is not approved by the Management
Committee within 21 days of its receipt thereof, then the Partners shall cause
their Representatives on the Management Committee to cooperate in good faith and
confer with the Chief Executive Officer for the purpose of attempting to arrive
at a Budget or Business Plan, as the case may be, that can secure the approval
of the Management Committee.

          (c)  If, notwithstanding the foregoing procedures, on January 1 of any
Fiscal Year no Proposed Budget has been approved by the Management Committee for
such Fiscal Year, then the Budget for the prior Fiscal Year, adjusted (without
duplication) to reflect (a) increases in the Consumer Price Index during the
prior year and (b)  increases or decreases

                                     -24-
<PAGE>

resulting from the following events, shall govern until such time as the
Management Committee approves a new Proposed Budget:

               (i)    the operation of escalation, de-escalation or other
     provisions in contracts in effect at the time of approval of the prior
     Fiscal Year's Budget solely as a result of the passage of time or the
     occurrence of events beyond the control of the Partnership to the extent
     such contracts are still in effect and have not been terminated;

               (ii)   elections made in any prior Fiscal Year under contracts
     contemplated by the Budget for such prior Fiscal Year regardless of which
     party to such contracts makes such election;

               (iii)  increases or decreases in expenses annualized effect of
     employee additions or reductions during the prior Fiscal Year contemplated
     by the Budget for such prior Fiscal Year;

               (iv)   interest expense attributable to any loans made to the
     Partnership (including Partner Loans);

               (v)    increases in overhead expenses in an amount equal to the
     total of overhead expenses reflected in the Budget for the prior Fiscal
     Year multiplied by the increase in the Consumer Price Index for the prior
     year, but in no event more than 5%;

               (vi)   the anticipated incurrence of costs during such Fiscal
     Year for any legal, accounting and other professional fees or disbursements
     in connection with events or changes not contemplated at the time of
     preparation of the Budget for the prior Fiscal Year;

               (vii)  the continuation of the effects of a decision made by
     the Management Committee or the Partners in the prior Fiscal Year with
     respect to any of the matters referred to in Section 6.05 or 6.06 that are
                                                  ------------    ----
     not reflected in the Budget for the prior Fiscal Year; provided, however,
                                                            --------  -------
     that no matter for which approval pursuant to Section 6.06 was required and
                                                   ------------
     obtained in one Fiscal Year shall be extended to the next Fiscal Year,
     except to the extent such matter was not fully executed during the first
     Fiscal Year, unless such matter is specifically approved pursuant to
     Section 6.06 for the year in question; and

               (viii) decreases in expense attributable to non-recurring
     items reflected in the prior Fiscal Year's Budget.

     Except as otherwise provided herein, any Budget established pursuant to
this Section 6.04(c) shall be deemed to have been approved by the Management
     ---------------
Committee.

Section 6.04 and is not approved by the Management Committee, the Business Plan

                                       --------
approved pursuant to Section 6.04(b) (as opposed to a Budget that is deemed
                     ---------------
approved pursuant to Section 6.04(c)), the Business Plan then in effect
                     ----------------
(including the aggregate amount of additional Capital Contributions contemplated
for the applicable Fiscal Year) shall be deemed to be amended so that the Fiscal
Year therein corresponding to the Fiscal Year for which such Budget has been
approved shall be consistent with such Budget.

     Section 6.05.    Actions Requiring Approval by a Majority of the Management
                      ----------------------------------------------------------
Committee.  Subject to Section 6.06, except to the extent expressly provided for
- - ---------              ------------

     employees with any form of equity interests in the Partnership or the

6.01(a), the Partnership may not take any action with respect to any of the

following matters (each, an "Extraordinary Decision") without the prior approval
of a majority of the Management Committee, which majority shall include the

               (i)    the consent to or implementation of any amendment to this
     Agreement in such a way as may adversely affect the rights of Tune and

     limiting the foregoing or any other provision of this Agreement, the

     Management Committee than MTVNS or, through contractual or other
     arrangements, assert greater control over the Partnership than MTVN.

     Section 6.07.    Limitation of Agency.  No Partner shall have any authority
                      --------------------
to act for or to assume any obligation or responsibility on behalf of the

by written agreement between the

                                     -27-
<PAGE>

Partners, or (iii) as provided herein. No Partner shall have any authority to
act for or assume any obligation or responsibility on behalf of another Partner
except as approved in writing by such other Partner. In addition to the other
remedies specified herein, each Partner agrees to indemnify and hold the
Partnership and the other Partner or any Affiliate thereof or any partner,
shareholder, director, officer, employee or agent of any of the foregoing
harmless from and against any claim, demand, loss, damage, liability or expense
(including reasonable attorneys' fees and disbursements and amounts paid in
settlement, but excluding any indirect, special or consequential damages)
incurred by or against such other Partner or the Partnership and arising out of
or resulting from any action taken by the indemnifying Partner in violation of
this Section 6.07.
     ------------

     Section 6.08.    Liability of Partners and Representatives.  Without
                      -----------------------------------------
limiting the duty of the General Partner under Delaware law to act in good
faith, except as set forth in Section 6.10, no Partner, former Partner or
                              ------------
Representative or former Representative, no Affiliate of any thereof, nor any
partner, shareholder, director, officer, employee or agent of any of the
foregoing, shall be liable, in damages or otherwise, to the Partnership or any
Partner for any act or failure to act in such Person's capacity as a Partner or
Representative or otherwise on behalf of the Partnership unless such act or
omission constituted fraudulent or willful misconduct, was performed or omitted
in bad faith or constituted gross negligence or in violation of this Agreement.
Each Partner, former Partner and Representative or former Representative, each
Affiliate of any thereof, and each partner, shareholder, director, officer,
employee and agent of any of the foregoing, shall be indemnified and held
harmless by the Partnership from and against any liability for damages and
expenses, including reasonable attorneys' fees and disbursements and amounts
paid in settlement, resulting from any threatened, pending or completed action,
suit or proceeding relating to or arising out of such Person's acts or omissions
in such Person's capacity as a Partner or Representative or (except as provided
in Section 6.07) otherwise involving such Person's activities on behalf of the
   ------------
Partnership, except to the extent that such damages or expenses result from the
bad faith, gross negligence, fraud or willful misconduct of such indemnified
Person or a violation by such Person of this Agreement or an agreement between
such Person and the Partnership.  Any indemnity by the Partnership under this
Section 6.08 shall be provided out of and to the extent of Partnership assets
- - ------------
only.  Notwithstanding anything to the contrary set forth in this Agreement,
except as otherwise expressly required by law, a Limited Partner, in its
capacity as such, shall have no liability in excess of (i) the amount of its
Capital Contribution, (ii) its share of any undistributed profits and assets of
the Partnership and (iii) the amount of any distributions wrongfully distributed
to it.

     Section 6.09.    Indemnification.  Any Person asserting a right to
                      ---------------
indemnification under Section 6.07 or 6.08 shall so notify the Partnership or
                      ------------    ----
the other Partners, as the case may be, in writing.  The indemnified Person's
failure to so notify the indemnifying Person of any such matter shall not
release the indemnifying Person, in whole or in part, from its obligations to
indemnify under this Section 6.09, except to the extent the indemnified Person's
                     ------------
failure to so notify actually prejudices the indemnifying Person's ability to
defend such action. If the facts giving rise to such indemnification shall
involve any actual or threatened claim or demand by or against a third party,
the indemnifying Person shall be entitled to control the defense or prosecution
of such claim or demand in the name of the indemnified Person, with counsel
satisfactory to the indemnified Person, if it notifies the indemnified Person in
writing of its

                                     -28-
<PAGE>

intention to do so within 20 days of its receipt of such notice, without
prejudice, however, to the right of the indemnified Person to participate
therein through counsel of its own choosing, which participation shall be at the
indemnified Person's expense unless (i) the indemnified Person shall have been
advised by its counsel that use of the same counsel to represent both the
indemnifying Person and the indemnified Person would present a conflict of
interest (which shall be deemed to include any case where there may be a legal
defense or claim available to the indemnified Person which is different from or
additional to those available to the indemnifying Person), or (ii) the
indemnifying Person shall fail vigorously to defend or prosecute such claim or
demand within a reasonable time, in which case the reasonable fees of counsel
for the indemnified Person shall be for the account of the indemnifying Person
and the indemnifying Person shall not have the right to direct the defense of
such action on behalf of the indemnified Person. Whether or not the indemnifying
Person chooses to defend or prosecute such claim, the Partnership and the
parties hereto shall cooperate in the prosecution or defense of such claim and
shall furnish such records, information and testimony and attend such
conferences, discovery proceedings, hearings, trials and appeals as may
reasonably be requested in connection therewith. The indemnifying Person shall
not settle or permit the settlement of any such third party claim or action in
which any relief other than the payment of money damages is sought against the
indemnified Person without the prior written consent of the indemnified Person
which consent shall not be unreasonably withheld. The indemnified Person shall
not settle or permit the settlement of any claim or action for which it is
entitled to indemnification without the prior written consent of the
indemnifying Person, unless the indemnifying Person shall have failed to assume
the defense thereof after the notice referred to in the first sentence of this
Section 6.09, and in the manner provided above.

     Section 6.10.    Right of Partners Against Partnership and General Partner
                      ---------------------------------------------------------
in Certain Events.  Notwithstanding anything herein to the contrary, so long as
- - -----------------
the Tune Minimum Condition is met and MTVNS owns a majority of the Partnership
Interests, in the event that the Partnership defaults under any of the
Programming License Agreement, the Trademark License Agreement or the Technology
Sharing and License Agreement, and, as a result of any such breach, MTVN or any
Controlled Affiliate seeks to terminate any such agreement pursuant to its
rights as Licensor thereunder, Tune shall have the right to bring and maintain
an action against the Partnership and/or the General Partner with respect to
such breach and, if applicable, a related breach of the duty of good faith; in
the event of any liability of the Partnership or the General Partner in any such
action, the General Partner shall not be entitled to any indemnification
hereunder from the Partnership. Tune shall be entitled to be reimbursed its
costs and reasonable expenses in bringing and maintaining such action without
regard to the outcome of such action.

     Section 6.11.    Temporary Right to Direct Management Committee.  In the
                      ----------------------------------------------
event of any breach by the Partnership of any of the Programming License
Agreement, the Trademark License Agreement or the Technology Sharing and License
Agreement in the circumstances set forth in Section 6.10 and the Partnership's
failure to cure such breach during the initial applicable cure period, then MTVN
shall take such actions, for a period of 30 days following the expiration of
such initial cure period, as may be reasonably requested by Tune to cause such
breach to be cured, including directing the Management Committee to take action,
subject to its fiduciary duties, to cause the Partnership to cure such breach as
requested by Tune.

two Business Days' notice from a Partner, the Partnership shall also provide
each Partner with a reasonable opportunity during ordinary business hours to
review and make copies of all work papers related to such schedule and
information or to any return provided under Section 7.03(b). The Tax Matters

this Agreement, the transferred Partnership Interest shall continue to be
subject to all the provisions of this Agreement, including the provisions of
this Article VIII, except that no transferee of the Tune Partnership Interest
     ------------
(other than a Permitted Transferee which is a member of the Tune Stockholder

any Disposition of all or any portion of the Tune Partnership Interest after the

withdraw from the Partnership, except with the prior written consent of the
other Partners.  Unless otherwise expressly agreed by the other Partners, the

Interest to a Permitted Transferee of such Partner without the consent of the
other Partners, provided that, unless otherwise agreed by the nontransferring
Partners, such Disposition (whether considered alone or taken together with
prior Dispositions) would not cause the Partnership to lose its status as a
Partnership for federal income tax purposes and would not result in the
violation of any applicable law.

it complies with Section 8.05(a) to the extent applicable and (ii) Tune and any

Permitted Transferee of Tune may Dispose of any or all of its Partnership

     Section 8.04.    Right of First Offer.
                      --------------------

     In the event that Tune or any Permitted Transferee of Tune desires to
Dispose of any or all of the Tune Partnership Interest at any time or from time
to time after the end of the Restricted Period to a Person other than a
Permitted Transferee, it shall notify MTVNS in writing of such desire at least
30 days prior to making any such Disposition.  MTVNS or its designee may, at any
time during such 30-day period prior to any such desired Disposition make an
offer to purchase such portion of the Tune Partnership Interest that Tune or its
Permitted Transferee has indicated it desires to Dispose of, which offer, if
accepted, shall constitute a valid and binding agreement subject to the
applicable provisions of Section 8.06.  Tune or any Permitted Transferee of Tune
shall, if requested by MTVNS, negotiate in good faith for a 30-day period
following the delivery of such notice by MTVNS or its designee (the "Negotiation
Period") to reach an agreement for the sale of the Tune Partnership Interest to
MTVNS.  If no such agreement is reached, MTVNS may confirm its prior offer or
make a new offer to Tune regarding the purchase of such portion of the Tune
Partnership Interest, which reconfirmed or new offer, if made, shall, if
accepted, constitute a valid and binding agreement subject to the applicable
provisions of Section 8.06.  If Tune or its Permitted Transferee elects to
accept such offer, it shall do so on the terms and subject to the conditions
specified in such offer (but MTVNS or its designee shall be obligated to pay
interest on the purchase price for any period from 90 days after acceptance of
such offer until the consummation thereof at an annual rate equal to LIBOR plus
1% unless the delay in such consummation is primarily attributable to any act or
failure to take a required action on the part of Tune or such Permitted
Transferee); if it elects not to accept such offer or if MTVNS fails to make any
such offer, Tune or its Permitted Transferee may, for a period of 180 days (or
270 days, if pursuant to a binding agreement entered into within 100 days) after
the earlier of (i) the receipt of the last bona fide offer from MTVNS or its
designee or (ii) the expiration of the Negotiation Period or the 30 day prior
notice period, if MTVNS does not request it to negotiate, Dispose of or agree to
Dispose of any or all of its Partnership Interest to any Person other than MTVNS
or its designee (x) if no such offer was made by MTVNS or its designee, at any
price or on any terms or conditions subject to compliance with the applicable
provisions of this Agreement, or (y) if any such offer was made, on terms
(including price (evaluated on an after-tax basis)) and other terms and
conditions, taken as a whole, which are no more favorable to the transferee than
those set forth in the last bona fide offer made by MTVNS or its designee.

     Section 8.05.    Tag Along; Drag Along.
                      ---------------------

          (a)         If at any time after the end of the Restricted Period and
prior to the sixth anniversary thereof, MTVNS and/or its Permitted Transferee(s)
(the "Transferring Partner") receives a bona fide third party offer (other than
in connection with a Disposition to a Permitted Transferee) to purchase or
otherwise acquire, in a single transaction or series of related transactions, an
aggregate amount of Partnership Interests such that the prospective
transferee(s) (together with their Affiliates) would beneficially own more than
50% of the total Capital Accounts of the Partners which such Transferring
Partner desires to accept, then such Transferring Partner shall offer to Tune
and/or its Permitted Transferee(s) (the "Other Partner(s)") the right to
participate in the proposed sale by written notice (the "Tag Along Notice")
delivered within 10 days after its tentative decision to accept such offer and
specifying

                                     -33-
<PAGE>

in reasonable detail the identity of the prospective transferee(s) and the terms
and conditions of such transaction(s). The Other Partner(s) may elect to
participate in the contemplated transaction(s) by delivering written notice to
the Transferring Partner within 15 days after delivery of the Tag Along Notice.
Each Other Partner shall be entitled to transfer the same fraction of its
interest in the Partnership as is transferred by the Transferring Partner (the
"Tag Along Transfer Fraction") and to receive an amount therefor which shall be
equal to (x) the product of (i) the Tag Along Transfer Fraction and (ii) such
Other Partner's Capital Account, plus (y) the "Premium Amount," if any, and
minus (z) the "Discount Amount," if any. The Premium Amount shall be equal to
the product of (i) (a) the excess, if any, of the purchase price for the
Transferred Interest over the Capital Account attributable to such Transferred
Interest divided by (b) the Percentage Interest in the Partnership represented
by such Transferred Interest, and (ii) the Percentage Interest in the
Partnership represented by the fraction of the Other Partner's interest in the
Partnership that is to be transferred pursuant to this Section. The Discount
Amount shall be equal to the product of (i)(a) the excess, if any, of the
Capital Account attributable to such Transferred Interest over the purchase
price for the Transferred Interest divided by (b) the Percentage Interest in the
Partnership represented by such Transferred Interest, and (ii) the Percentage
Interest in the Partnership represented by the fraction of the Other Partner's
interest in the Partnership that is to be transferred pursuant to this Section.
For this purpose, "Transferred Interest" means the interest in the Partnership
to be sold by the Transferring Partner. If the Disposition of the Transferring
Partner's Partnership Interest is pursuant to a series of related transactions,
then the purchase price for the interest of the Other Partner(s) shall be
determined as above by using the weighted average of the amounts offered to the
Transferring Partner. Each Transferring Partner shall use reasonable efforts to
obtain the agreement of the prospective transferee(s) to the participation of
the Other Partner(s) in any such contemplated transaction(s), and no
Transferring Partner shall transfer any of its Partnership Interests to any
prospective transferee if such prospective transferee(s) declines to allow the
participation of the Other Partner(s).

          (b)         If at any time after the end of the Restricted Period and
prior to the sixth anniversary thereof, the Transferring Partner receives a bona
fide third party offer to purchase or otherwise acquire, in a single transaction
or series of transactions, an aggregate amount of Partnership Interests such
that the prospective transferee(s) (together with their Affiliates) would
beneficially own more than 50% of the total Capital Accounts of the Partners and
otherwise control the Partnership through control of a majority of the
Representatives which such Transferring Partner desires to accept, then the
Transferring Partner shall provide each of the Other Partner(s) with notice of
such offer, and, if the Transferring Partner so elects, notice that the
Transferring Partner requires the Other Partner(s) to participate in such sale
with respect to the same percentage of its or their Partnership Interests as are
proposed to be sold by the Transferring Partner (the "Drag Along Notice")
delivered within 10 days after its tentative decision to accept such offer and
specifying in reasonable detail the identity of the prospective transferee(s)
and the terms and conditions of such transaction(s). The Other Partner(s) will
thereafter be required to include its or their Partnership Interests in such
sale and to use its or their reasonable efforts to cooperate in such sale. If
the Transferring Partner elects to exercise its rights under this Section
                                                                  -------
8.05(b), it may require each Other Partner to transfer up to the same fraction
- - -------
of its or their interest in the Partnership as is transferred by the
Transferring Partner in such transaction or series of related transactions (the
"Drag Along Transfer Fraction"), and to

                                     -34-
<PAGE>

receive an amount therefor which shall be equal to (x) the product of (i) the
Drag Along Transfer Fraction and (ii) such Other Partner's Capital Account, plus
(y) the Premium Amount, if any, and minus (z) the Discount Amount, if any. The
Premium Amount shall be equal to the product of (i) (a) the excess, if any, of
the purchase price for the Transferred Interest over the Capital Account
attributable to such Transferred Interest divided by (b) the Percentage Interest
in the Partnership represented by such Transferred Interest, and (ii) the
Percentage Interest in the Partnership represented by the fraction of the Other
Partner's interest in the Partnership that is to be transferred pursuant to this
Section. The Discount Amount shall be equal to the product of (i)(a) the excess,
if any, of the Capital Account attributable to such Transferred Interest over
the purchase price for the Transferred Interest divided by (b) the Percentage
Interest in the Partnership represented by such Transferred Interest, and (ii)
the Percentage Interest in the Partnership represented by the fraction of the
Other Partner's interest in the Partnership that is to be transferred pursuant
to this Section. For this purpose, "Transferred Interest" means the interest in
the Partnership to be sold by the Transferring Partner. If the Disposition of
the Transferring Partner's interest in the Partnership is pursuant to a series
of related transactions, then the purchase price for the interest of the Other
Partner(s) shall be determined as above by using the weighted average of the
amounts offered to the Transferring Partner. Notwithstanding the foregoing,
MTVNS shall have no rights to require Tune to participate in a sale pursuant to
this Section 8.05(b) if MTVNS Disposes of less than all of its Partnership
     ---------------
Interest in a transaction or series of transactions that will result in, by
agreement or arrangement with the applicable transferee of such Partnership
Interest, Viacom Inc. and its Affiliates holding a 50% or greater interest in
the Partnership or otherwise controlling the Partnership, either directly or
through the acquisition or ownership of a direct or indirect interest in the
transferee of such Partnership Interest, within twelve months of such
Disposition.

          (c)         In connection within any purchase and sale of an Other
Partner's Partnership Interest pursuant to Section 8.05(a) or 8.05(b), such
                                           ---------------    -------
Other Partner shall become a party to any agreement with the purchaser but shall
not be required to make any representation and warranty other than
representations and warranties that (i) upon payment of the applicable purchase
price therefor, the applicable purchaser shall own such Partnership Interest
free and clear of any Liens other than any Liens created by this Agreement, any
Additional Agreement, MTVNS or such purchaser, (ii) such Other Partner has the
necessary corporate, partnership or limited liability company (as applicable)
power and authority to Dispose of such Partnership Interest and (iii) such
Disposition has been duly and validly authorized by all necessary corporate,
partnership or limited liability company (as applicable) action on the part of
such Other Partner and is not in violation of any laws, agreements or decrees
applicable to such Other Partner. The rights set forth in Sections 8.05(a) and
                                                          ----------------
8.05(b) shall survive any purported exercise of such rights with respect to any

proposed acquisition in the event such proposed acquisition is not consummated.

     accountants and other costs and expenses reasonably incurred by the
     Partnership as a result of such Disposition shall be paid by the transferee
     of a Partnership Interest;

               (ii)   the transferee of a Partnership Interest shall, by written
     instrument in form and substance reasonably satisfactory to the
     nontransferring Partners (and, in the case of clause (C) below, the
     transferor Partner), (A) make representations and warranties to the
     nontransferring Partners equivalent to those set forth in Article XIII, (B)
     accept and adopt the terms and provisions of this Agreement and, in the
     event of a Disposition of any portion of the Tune Partnership Interest, the
     Parent Agreement and (C) assume the obligations of the transferor Partner
     under this Agreement with respect to the transferred Partnership Interest,
     whereupon the transferor Partner shall be released from all such
     obligations and unless expressly assumed by the transferee with the consent
     of the Management Committee, except for (x) those obligations or
     liabilities of the transferor Partner arising out of a breach of this
     Agreement prior to the date of such Disposition or pursuant to Section
                                                                    -------
     6.09, Section 8.06(b), Section 12.03, and Section 15.14 and (y) those
     ----  ---------------  -------------      -------------
     obligations or liabilities of the transferor Partner based on events
     occurring, arising or maturing prior to the date of Disposition (other
     than, in the case of a Disposition or Transfer of a Partnership Interest by
     one Partner to another Partner or its designee, any such obligation or
     liability referred to in this clause (y) that is taken into account in the
     determination of the purchase price for the transferor Partner's
     Partnership Interest);

               (iii)  if required by the Management Committee, the transferee
     shall deliver to the Management Committee evidence of the authority of such
     Person to become a Partner and to be bound by all of the terms and
     conditions of this Agreement and the transferee and transferor shall each
     execute and deliver such other instruments and such opinions of counsel as
     the Management Committee reasonably deem necessary or appropriate to
     effect, and as a condition to, such Disposition, including amendments to
     the Certificate or any instrument filed with the State of Delaware or any
     other state or governmental agency;

               (iv)   no Disposition shall result in termination of, relieve the
     Partnership, the transferor Partner or any of its Affiliates from or
     otherwise affect any of the obligations or liabilities of the Partnership,
     the transferor Partner or any of its Affiliates under, any agreement
     between the transferor Partner or such Affiliate and the Partnership
     (including any Additional Agreement), except to the extent otherwise
     provided therein or otherwise agreed by the Management Committee;

               (v)    if required by the Management Committee, the transferee
     shall deliver to the Partnership an opinion, satisfactory in form and
     substance to the nontransferring Partners, of counsel reasonably
     satisfactory to the Management Committee to the effect that the Disposition
     of the Partnership Interest would not cause the Partnership to lose its
     status as a Partnership for federal income tax purposes; and

                                     -36-
<PAGE>

               (vi)   the Disposition of a Partnership Interest shall comply
     with all applicable state and federal securities laws and regulations and
     all other applicable laws.

          (b)     Any such Disposition of a Partner's Partnership Interest to
another Partner (or such Partner's designee) in accordance with this Article
VIII or Article XII shall be consummated as soon as practicable.  If any
Disposition of a Partner's Partnership Interest in accordance with this Article
                                                                        -------
VIII or Article XII requires the consent, approval, waiver, or authorization of
- - ----    -----------
any Governmental Entity, or the filing with any Governmental Entity and the
expiration of any waiting period, as a condition to the valid Disposition of
such Partner's Partnership Interest to the proposed transferee thereof, then
each of the time periods provided in this Article VIII or Article XII, as
                                          ------------    -----------
applicable, shall be suspended for the period of time during which any such
consent, approval, waiver, or authorization is being diligently pursued or until
any such waiting period expires; provided, however, that in no event shall the
                                 --------  -------
suspension of any time period pursuant to this Section 8.06 exist for more than
                                               ------------
180 days.  Subject to Section 8.06(c), each of the Partners agrees to use its
                      ---------------
diligent efforts to obtain, or to assist the affected Partner or Partnership in
obtaining, any such consent, approval, waiver, or authorization and shall
cooperate and use its diligent efforts to respond as promptly as practicable to
all inquiries received by it, by the affected Partner or by the Partnership from
any Governmental Entity for initial or additional information or documentation
in connection therewith.  In the event any such consent, approval, waiver or
authorization is not obtained or the expiration of any such waiting period does
not occur within such 180-day period, then if the proposed Disposition is to
MTVNS or its designee pursuant to Section 12.03 or Section 8.04, MTVNS shall,
                                  -------------    ------------
within 20 days of the earlier of the expiration of such 180 day period or such
date as it becomes probable that such consent or approval will not be received,
designate another Person to purchase the Partnership Interests proposed to be
acquired (which Person MTVNS shall in good faith believe would be an acceptable
purchaser of such Partnership Interest for purposes of obtaining such consent,
approval or expiration) at the same purchase price required to be paid for such
Partnership Interest, or at a lower price, in which case MTVNS shall pay to Tune
and/or its Permitted Transferees, as applicable, the excess of the specified
purchase price over such lower price.  Such sale to such a designee shall be
consummated as soon as practicable, but in no case more than 90 days following
the appointment of such alternate purchaser.

          (c)     Notwithstanding any provisions hereof to the contrary, nothing
contained in this Agreement shall obligate any of the Partners or any of their
respective Affiliates to take any action to consummate the Disposition of a
Partnership Interest and the other transactions contemplated hereby, the
consummation of which is dependent or conditioned on the receipt of any
governmental or regulatory approval or consent, in the event that the approval
or consent so received specifically includes conditions or restrictions in
addition to those imposed by laws and regulations of general applicability as in
effect from time to time (including conditions in addition to those imposed by
existing laws and regulations which require the prior approval of any
Governmental Entity to the taking of any action or the consummation of any
transaction), the direct or indirect effect of which is or would be, to
restrict, limit or otherwise subject to penalty any of the Partners or their
respective Affiliates in the ownership of their respective assets or the conduct
of their respective businesses. For purposes of the foregoing, a condition,
restriction or limitation arising out of any such approval or consent shall be
deemed to

                                     -37-

be a restriction or limitation on any such Person (regardless of whether such
Person is a party to or otherwise legally obligated by such consent or approval)
to the extent that the taking of an action or the consummation of a transaction
by such Person would result in any such Person or its Affiliates being in breach
or violation of such consent or approval or otherwise causing such consent or
approval to terminate or expire.

if:

     Partnership Interest, or suffers such Disposition to occur, except as
     permitted by this Agreement; provided, however, that, so long as no
                                  --------  -------
     foreclosure action has commenced with respect to such Partnership Interest,
     no Event of Default shall be considered to have occurred for 30 days
     following the involuntary encumbrance of all or any part of such
     Partnership Interest if during such 30-day period such Partner acts
     diligently to, and does, remove any such encumbrance, including effecting
     the posting of a bond to prevent foreclosure where necessary;

               (ii)   any Partner fails to make all or any portion of any
     Required Contribution when due and such failure continues for more than
     five days following notice thereof from the Chief Executive Officer or
     MTVNS;

               (iii)  Such Partner or any Affiliate of such Partner willfully
     fails to perform or violates any other material term or condition of this
     Agreement (except to the extent any such failure to perform or violation
     results from or arises out of a good faith dispute with respect to this
     Agreement) and such failure or violation continues for 30 days after
     written notice thereof has been given by the other Partner (or if such
     failure or violation is not a failure to pay money and is of such a nature
     that it cannot reasonably be cured within such 30-day period, but it is
     curable and such Partner in good faith begins efforts to cure it within
     such 30-day period and continues diligently to do so, such reasonable
     additional period thereafter to effect the cure (but no more than an
     additional 30 days)); or

     Partnership in contravention of the terms of this Agreement (other than
     solely by virtue of the Bankruptcy of such Partner).

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

          (a)         Upon the occurrence and during the continuance of an Event
of Default, (i) the Defaulting Partner shall have no right to designate any
Representatives pursuant to Section 6.01 and (ii) any appointment of any
                            ------------
Representatives previously designated by the Defaulting Partner to the
Management Committee shall be void and of no effect until such time as such
Event of Default is cured in full or waived by each Non-Defaulting Partner (as
defined below), and no other Event of Default with respect to such Defaulting
Partner has occurred and is continuing. In all other respects a Defaulting
Partner shall continue to have all of the rights and obligations of a Non-
Defaulting Partner under this Agreement and applicable law. Commencing on the
date that any Partner loses its right to designate Representatives pursuant to
this Section 9.02 until the earlier of the date that such Partner (i) regains
     ------------
the right to designate Representatives under this Agreement or (ii) Disposes of
all of its Partnership Interest in accordance with this Agreement, such Partner
shall be permitted to send one representative to act as an observer to each
meeting of the Management Committee.  Such observer shall not be permitted to
vote or participate in such meeting and may be asked to leave the meeting at any
point during which the Management Committee is discussing matters relating to
such Partner.  In such event the quorum requirements for the Management
Committee shall be appropriately revised to the extent necessary to carry on the
business of the Partnership.

          (b)         Upon the occurrence and during the continuance of an Event
of Default, with respect to a Defaulting Partner, the other Partner (assuming no
Events of Default are continuing with respect to it) (the "Non-Defaulting
Partner"), in addition to any other rights it may have hereunder or under any
applicable law, may elect to seek to enjoin such default or to obtain specific
performance of a Defaulting Partner's obligations or Damages (as defined below)
in respect of such Event of Default. The foregoing remedies shall not be deemed
mutually exclusive, and selection or resort to any thereof shall not preclude
selection or resort to the others. The resort to any remedy pursuant to this
ection 9.02(b) shall not for any purpose be deemed to be a waiver of any other
- - --------------
remedy available hereunder or under applicable law and the failure to elect a
remedy within the time period provided in the preceding paragraph shall not be
presumed to be a waiver of such Event of Default.

          (c)         Unless an Event of Default or resort to such remedy has
been waived as set forth in the immediately preceding paragraph, the Partnership
or the Non-Defaulting Partner shall be entitled to recover from the Defaulting
Partner in an appropriate proceeding any and all damages, losses and expenses
(including reasonable attorneys' fees and disbursements) (collectively,
"DAMAGES") suffered or incurred by the Partnership or the Non-Defaulting Partner
as a result of such Event of Default.

          (a)          The Management Committee shall cause to be prepared a
statement of the assets and liabilities of the Partnership as of the date of

and properties of the Partnership shall be liquidated as promptly as possible,
and receivables collected, all in an orderly and business-like manner so as not
to involve undue sacrifice. Notwithstanding the foregoing, the Management
Committee may determine not to sell, or authorize the sale of, all or any
portion of the assets and properties of the Partnership, in which event such
assets and properties shall be distributed in kind pursuant to Section 10.02(c).

all other assets and properties of the Partnership shall be applied and
distributed as follows in the following order of priority:

     Partnership (except for Partner Loans and any other amounts which may be
     owed to any Partner) and the expenses of liquidation;

               (ii)      to establish any reserves as the Management Committee,
     in accordance with sound business judgment, deems reasonably necessary for
     any contingent or unforeseen liabilities or obligations of the Partnership,
     which reserves may be paid over by the Management Committee to an escrow
     agent selected by it to be held by such agent for the purpose of (x)

     unpaid principal amount of the Partner Loans on a pro rata basis to each

     total amount in each Partner's Capital Account (as adjusted in accordance
     with Section 5.01) to reflect allocations of Net Income and Net Loss

     (including any items thereof resulting from distributions of assets in
     kind). Any distribution pursuant to this Section 10.02(c)(iv) shall be made

     prior to the later of (A) the end of the Partnership taxable year in which
     the liquidation of the Partnership occurs or (B) 90 days after the date of
     such liquidation. Distributions pursuant to this Section 10.02(c)(iv) may

     the purposes of liquidating Partnership assets, collecting amounts owed to
     the Partnership and paying any contingent or unforeseen liabilities or
     obligations of the Partnership or of any Partner arising out of or in
     connection with the Partnership. The assets of any such trust shall be
     distributed to the Partners from time to time, in the reasonable discretion
     of the Management Committee, in the same proportions as the amount
     distributed to such trust by the Partnership would otherwise have been
     distributed to the Partners pursuant to this Agreement.

               (d)     Except with respect to the Reorganization, nothing
contained in this Section 10.02 shall be construed to limit the Management

Committee's discretion to attempt to sell the Partnership's business and assets
as a going concern following the occurrence of an Event of Termination, provided
that the proceeds of such sale shall be applied and distributed as provided in
Section 10.02(c), and provided, further, that if such a sale cannot be effected
- - ---------------       --------  -------
within six months after the occurrence of an Event of Termination (or such
longer or shorter period as the Partners may agree) then the Management
Committee shall promptly proceed to wind-up the affairs of the Partnership as
provided above in this Section 10.02.

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

     Section 11.01.    Related Party Transactions Generally.
                       ------------------------------------

               (a)     Prior to consummation of the IPO, any Related Party
Transaction(s) shall be undertaken and conducted on an arm's length basis and on
terms, in the aggregate, no less favorable to the Partnership than could be
obtained from an unaffiliated third party. Tune shall have the right,
exercisable no more than once during a twelve-month period, to designate a
Person who is not an Affiliate of any Partner (the "Auditor"), subject to the
approval of MTVNS, which approval shall not be unreasonably withheld, to audit
any Related Party Transaction(s) conducted during the period since any previous
such audit. If the Auditor determines that (i) the Related Party Transactions
undertaken or conducted during such period were, in the aggregate, not on arm's
length terms and on terms which were less favorable to the Partnership than
those that could be obtained from an unaffiliated third party and (ii) the
difference between (x) the economic value of each such Related Party Transaction
and (y) the economic value of such transaction had it been entered into on an
arm's length basis with an unaffiliated third party, in the aggregate, exceeds
the greater of (1) 10% of the aggregate economic value of each Related Party
Transaction whose economic value exceeds that of the economic value of such
transaction had it been entered into with an unaffiliated third party (each such
Related Party Transaction, a "Subject Transaction") and (2) $1,000,000, then the
terms of each such Subject Transaction shall be modified such that, for all
future periods covered by such

                                     -41-
<PAGE>

transaction, such Related Party Transaction will be on terms no less favorable
than those which could be obtained from an unaffiliated third party and the
Affiliates of MTVNS which were parties to such Related Party Transaction shall
reimburse the Partnership retroactively to the time such Subject Transaction(s)
was implemented for the full economic value by which such Related Party
Transaction exceeded the value of an arm's-length transaction with an
unaffiliated third party, in each case as determined by the Auditor ("Auditor's
Findings") and MTVNS shall pay the costs and expenses associated with such audit
(the "Audit Costs"). If the Auditor determines that no such payment or
modification is required, Tune shall pay for such Audit Costs.

               (b)     If any Partner disagrees with the Auditor's Findings,
such Partner (the "Notifying Party") shall deliver a written notice thereof (the
"Dispute Notice") to the other Partners (the "Receiving Party") within 30 days
after receipt of the Auditor's Findings. If no Dispute Notice is received within
such 30-day period, the Auditor's Findings shall be final and binding on the
Partners and the Partnership. Upon receipt by the Receiving Party of the Dispute
Notice, MTVNS and Tune shall negotiate in good faith to resolve any disagreement
with respect to the Auditor's Findings. If MTVNS and Tune are unable to agree
with respect to the Auditor's Findings within 30 days after receipt by the
Receiving Party of the Dispute Notice, MTVNS and Tune shall promptly submit
their dispute to an arbitrator with no material relationship to MTVNS or Tune or
their respective Affiliates, selected by the Notifying Party and reasonably
satisfactory to the Receiving Party, for a binding resolution. The cost of the
arbitration will be borne as determined by the arbitrator.

     Section 11.02.    Related Party Transactions in Excess of $1,000,000.
                       --------------------------------------------------

               (a)     Prior to consummation of the IPO, in the event that the
Partnership or any Controlled Affiliate thereof proposes to engage in a Related
Party Transaction(s) which involves in the aggregate amounts (or has economic
value) (in any one transaction or in a series of related transactions) in excess
of $1,000,000, the Partnership shall, prior to entering into or engaging in such
Related Party Transaction, deliver written notice to Tune of its intent to enter
into such Related Party Transaction, which notice will contain an accurate and
complete description of such Related Party Transaction (a "Related Party
Transaction Notice"). Within ten days after its receipt of such notice, Tune may
either (x) approve such transaction in writing by notice to the Partnership
(with such approval deemed granted in the event Tune fails to raise an objection
to such Related Party Transaction within 10 days following receipt of such
notice of the Related Party Transaction) or (y) object in writing to such
Related Party Transaction. If Tune so approves (or such approval is deemed
granted), then the Partnership may engage in such Related Party Transaction on
the terms set forth in its notice to Tune. If Tune so objects, it shall
thereafter promptly designate a Person who is not an Affiliate of any Partner
(the "Appraiser"), subject to the approval of MTVNS, which approval shall not be
unreasonably withheld, to review the financial terms of such proposed Related
Party Transaction(s). If the Appraiser determines (the "Appraiser's Findings")
that the difference between (x) the economic value of such proposed Related
Party Transaction and (y) the economic value of such transaction if entered into
on an arm's length basis with an unaffiliated third party, equals or exceeds 10%
of the net present value (using a 10% discount rate) of the economic value of
such proposed Related Party Transaction, then the Partnership and the other
party to such Related Party Transaction shall elect either not to engage in the
proposed Related Party Transaction(s) or to modify its financial terms

                                     -42-
<PAGE>

such that, for all future periods covered by such transaction, such Related
Party Transaction will be on terms no less favorable than those which could be
obtained from an unaffiliated third party. The cost and expenses associated with
such Appraisal shall be borne by Tune unless the Partnership determines not to
enter into the transaction or the transaction requires adjustment as specified
above, in which case such costs and expenses shall be borne by MTVNS.

               (b)     If any Partner disagrees with the Appraiser's Findings,
such Partner (the "Appraiser Notifying Party") shall deliver a written notice
thereof ("Appraiser Dispute Notice") to the other Partners (the "Appraiser
Receiving Party") within 30 days after receipt of the Appraiser's Findings. If
no Appraiser Dispute Notice is received within such 30-day period, the
Appraiser's Findings shall be final and binding on the Partners and the
Partnership. Upon receipt by the Appraiser Receiving Party of the Appraiser
Dispute Notice, MTVN and Tune shall negotiate in good faith to resolve any
disagreement with respect to the Appraiser's Findings. If MTVN and Tune are
unable to agree with respect to the Appraiser's Findings within 30 days after
receipt by the Appraiser Receiving Party of the Appraiser Dispute Notice, MTVN
and Tune shall promptly submit their dispute to an arbitrator with no material
relationship to MTVN or Tune or their respective Affiliates selected by the
Appraiser Notifying Party and reasonably satisfactory to the Appraiser Receiving
Party for a binding resolution. The cost of the arbitration will be borne as
determined by the arbitrator.

     Section 11.03.    Basis of Evaluation.  In evaluating the economic value
                       -------------------
of a Related Party Transaction as compared to a transaction with an unaffiliated
third party, the Auditor or Appraiser, as the case may be, shall determine the
economic value of a transaction with an unaffiliated third party based upon a
transaction with respect to the same or a reasonably similar service or product
(regardless of whether such service or product is unique, it being understood,
however, that the Auditor or Appraiser is entitled to assign a premium to the
unique aspects of a product or service), to be provided by Persons which are
similarly situated or comparable to the Persons which are to be parties to the
Related Party Transaction.

     Section 11.04.    No Breach.  If the terms of any Related Party
                       ---------
Transaction are modified as provided in this Article XI and any obligations
                                             ----------
arising from such modification are satisfied, no party to such Related Party
Transaction shall be in breach of any obligation hereunder solely by reason of
having entered into such Related Party Transaction on the original terms.

                                  ARTICLE XII

                   CERTAIN PROVISIONS RELATING TO INTERESTS
                   ----------------------------------------

     Section 12.01.    Adjustment of Tune's Percentage Interest.  If, by the
                       ----------------------------------------
Offering Expiration Date, the IPO has not been consummated, Tune may, by written
notice to the Partnership (the "Tune Notice"), within the six-month period
commencing on the Offering Expiration Date, require that the Tune Partnership
Interest Value as of the Offering Expiration Date be determined. If the Tune
Partnership Interest Value as of the Offering Expiration Date is determined to
be less than the Target Value and provided that neither TCI Music nor Tune nor
any of their Controlled Affiliates is in material default of its obligations
under this Agreement or the Additional Agreements, then the Partnership, without
any additional consideration (other

                                     -43-
<PAGE>

than any nominal consideration required by law) from Tune, shall (subject to the
last sentence of this Section 12.01) increase (in the same proportions) Tune's
                      -------------
Percentage Interest and Capital Account balance (and correspondingly reduce
MTVN's Percentage Interest and Capital Account balance) so the Tune Partnership
Interest Value (based on Tune's Percentage Interest as increased pursuant to
this Section 12.01) as of the Offering Expiration Date shall be equal to the
     -------------
Target Value (as reduced proportionally to reflect any Disposition of any
portion of the Tune Partnership Interest prior to the Offering Expiration Date);
provided, however, that such Percentage Interest shall in no event exceed 15%
- - --------  -------
(or such lesser percentage which equals 150% of Tune's Percentage Interest on
the Offering Expiration Date); and provided, further, however, that Tune may
                                   --------  ------- --------
elect to defer receipt and the effectiveness of such increase until the first to
occur of (x) the IPO, (y) such date as Tune shall request such increase or (z)
the first anniversary of the Offering Expiration Date.

     Section 12.02.    Preemptive Rights.  MTVNS and Tune, so long as Tune is
                       -----------------
permitted to designate one Representative to the Management Committee pursuant
to Sections 6.01(a), shall have certain preemptive rights as follows:
   ----------------

               (a)     If the Partnership wishes to issue any Partnership
Interests or rights to acquire such Partnership Interests (in either case, the
"Offered Interests") after the date hereof to any Person, the Partnership shall
give each Partner at least 15 days prior written notice of any proposed
issuance, which notice shall disclose in reasonable detail the proposed terms
and conditions of such issuance (the "Issuance Notice"). Upon receipt of the
Issuance Notice, each Partner shall have the right to elect to purchase, at the
same price and on the terms stated in the Issuance Notice, a percentage of
Offered Interests equal to the product of (x) such Partner's Percentage
Interest, multiplied by (y) the total Percentage Interest represented by all of
the Offered Interests to be issued. Those Partners electing to purchase Offered
Interests shall be referred to as "Electing Partners". Such election is to be
made by each Partner by delivering written notice to the Partnership and the
other Partners within 15 days after receipt by such Partner of the Issuance
Notice (the "Acceptance Period"). The delivery of such notice by an Electing
Partner shall constitute a binding offer by such Electing Partner to purchase
that portion of the Offered Interest specified in such notice on the terms set
forth in the Issuance Notice, which offer shall be irrevocable for a period of
90 days following its delivery to the Partnership. The Partnership shall be
required to accept any such offer from an Electing Partner and issue such
Partnership Interests to it so long as such Electing Partner has offered to
purchase its proportionate share of the Offered Interests as provided above.

               (b)     If Tune and its Permitted Transferees have not elected to
purchase their percentage of the Offered Interests, MTVNS and its Permitted
Transferees shall have the right to elect to purchase such percentage of the
Offered Interests (the "Excess Interests"), by giving written notice of such
election to the Partnership within 10 days after the Acceptance Period, so long
as all of the Excess Interests are to be purchased by the Electing Partners.

               (c)     If Tune does not elect to purchase its share of the
Offered Interests pursuant to Section 12.02(a), then Tune and its Permitted
                              ----------------
Transfereesshall have no right to purchase any Offered Interests pursuant to
this Section 12.02, and/or if MTVNS fails to purchase its Offered Interests (or
     -------------
all Offered Interests, if Tune is not an Electing Partner) the Partnership

                                     -44-
<PAGE>

may, at its election, during a period of 90 days following the expiration of the
Acceptance Period, sell and issue such Offered Interests not elected to be
purchased to such other Person at a price and upon terms no more favorable to
such Person than those stated in the Issuance Notice; provided that as a
condition to such sale, such Person acquiring the Offered Interests becomes a
party to this Agreement and the ultimate parent entity of such Person becomes a
party to the Parent Agreement and Guaranty on such terms as the Management
Committee shall reasonably approve. In the event the Partnership has not so sold
the Offered Interests within such 90-day period, the Partnership shall not
thereafter issue or sell any of such Offered Interests or any other additional
Partnership Interests without first offering such securities to each Partner in
the manner provided in this Section 12.02.
                            -------------

               (d)     If Tune and its Permitted Transferees and/or MTVNS and
its Permitted Transferees give the Partnership notice, pursuant to the
provisions of this Section 12.02, that Tune and its Permitted Transferees and/or
                   -------------
MTVNS and its Permitted Transferees (as the case may be) desire to purchase all
of the Offered Interests as to which they have the right to purchase pursuant to
this Section 12.02, such sale shall be consummated within ten days after the
     -------------
Acceptance Period. In the event that any proposed issuance is for a
consideration other than cash, the Partners will be entitled to pay cash for
each share or other unit, in lieu of such other consideration, in the amount
determined in good faith by the Management Committee in accordance with Section
                                                                        -------
6.06 (to the extent a purchaser is an Affiliate of Viacom) to constitute the
- - ----
Fair Market Value of such consideration other than cash to be paid per share or
other unit or, to the extent Tune and the Partnership so agree, to deliver
property or securities having an Agreed Value equal to such Fair Market Value.

               (e)     The preemptive rights contained in this Section 12.02
                                                               -------------
shall not apply to (i) the grant or sale of Partnership Interests or rights to
acquire Partnership Interests to officers, directors, consultants,
Representatives or employees of the Partnership or its Controlled Affiliates
approved after the date hereof by the Management Committee in accordance with
Sections 6.05 and 6.06 or to the sale or issuance of Partnership Interests to
- - ------------      ----
directors, employees or consultants of MTVN or Viacom pursuant to an employee,
consultant or director option plan in compliance with this Agreement or (ii) the
issuance of Partnership Interests to the public in the IPO or thereafter;
provided, however, that after the IPO Tune shall have preemptive rights with
- - --------  -------
respect to any offering of Partnership Interests or rights to acquire
Partnership Interests made to MTVN or its Affiliates.

     Section 12.03.    Put and Call.
                       ------------

               (a)     At any time during the 60-day period commencing on the
fifth anniversary of the Closing Date, each Subject Transferee may, by written
notice to MTVNS (the "Put Notice"), require MTVNS to purchase all, but not less
than all, of the Tune Partnership Interest held by such Subject Transferee. Any
such purchase or sale shall be effected, for cash, on the date which is the
120th day following the fifth anniversary of this Agreement, or (if not a
Business Day) the next following Business Day (the "Put Closing Date") and at a
price equal to the product of (x) the Tune Partnership Interest Value with
respect to the aggregate amount of the Tune Partnership Interests covered by the
Put Notices (the "Put Interest") as of the fifth anniversary of the date hereof
and (y) a fraction, the numerator of which is the Percentage

                                     -45-
<PAGE>

Interest of the Put Interest on the Put Closing Date and the denominator of
which is the Percentage Interest of the Put Interest on such fifth anniversary
(excluding, in each case, any changes in such Percentage Interest resulting
other than from a Disposition of any portion of the Put Interest during such
period) (the "Put Purchase Price"). The Put Purchase Price will be allocated
proportionately among all Subject Transferees electing to exercise the Put and
selling their Tune Partnership Interests to MTVNS. The Put Purchase Price shall
bear interest at an annual rate of LIBOR plus 1% for any period from the date
which is 90 days after the date of the Put Notice until the Put Closing Date
unless the delay in such consummation is primarily attributable to any act or
failure to take a required action on the part of Tune or such subject
Transferee. A "Subject Transferee" shall mean each of (i) Tune or its Permitted
Transferees or (ii) a transferee of any or all of the Tune Partnership Interest
which acquired such Tune Partnership Interest in accordance with the terms of
this Agreement; provided, that no transferee acquiring any or all of the Tune
                --------
Partnership Interest in a public market transaction (so long as such sale to
such transferee in such public market transaction was made in accordance with
this Agreement) shall be a Subject Transferee; provided, further, that a Subject
                                               --------  -------
Transferee holding Tune Partnership Interests acquired both (A) pursuant to this
Agreement (other than in a public market transaction) and (B) in a public market
transaction, shall be a Subject Transferee only as to the Tune Partnership
Interests not acquired in a transaction referred to in clause (B) above.

               (b)     At any time during the 60-day period commencing on the
sixth anniversary of the Closing Date, MTVNS (whether or not it is then a
Partner) may, by written notice to each Subject Transferee (the "Call Notice"),
require each Subject Transferee to sell to MTVNS all, but not less than all, of
the Tune Partnership Interest. Any such purchase or sale shall be effected, for
cash, on the date which is the 120th day following the sixth anniversary of this
Agreement, or (if not a Business Day) the next following Business Day (the "Call
Closing Date"), and at a price equal to the product of (x) the Tune Partnership
Interest Value as of the sixth anniversary of the date hereof and (y) a
fraction, the numerator of which is the Percentage Interest of the Tune
Partnership Interest on the Call Closing Date and the denominator of which is
the Percentage Interest of the Tune Partnership Interest on such sixth
anniversary (excluding, in each case, any changes in such Percentage Interest
resulting other than from a Disposition of any portion of the Tune Partnership
Interest during such period) (the "Call Purchase Price"). The Call Purchase
Price shall bear interest at an annual rate of LIBOR plus 1% for any period from
the date which is 90 days after the date of the Call Notice until the Call
Closing Date unless the delay in such consummation is primarily attributable to
any act or failure to take a required action on the part of Tune or such Subject
Transferee.

               (c)     If a Put Notice or Call Notice is delivered, as the case
may be, then MTVNS and Tune shall proceed with the closing of the purchase (the
"PUT/CALL CLOSING") in accordance with Section 8.06(b) as follows:
                                       ---------------

                   (i)     The Put/Call Closing shall be held at the principal
     office of the Partnership on the Put Closing Date or Call Closing Date, as
     the case may be, or at such other place or on such other date as MTVNS and
     Tune may agree, provided that MTVNS shall have the right to designate
     another reasonably convenient location to avoid stamp duty or other
     transfer taxes to the extent that it is not unlawful to do so.

                                     -46-
<PAGE>

                   (ii)    At the Put/Call Closing, MTVNS shall purchase (or
     cause its designee to purchase) all but not less than all of the applicable
     Tune Partnership Interest for the Put Purchase Price or the Call Purchase
     Price, as the case may be, and against payment of such price in cash, the
     Subject Transferee(s) shall deliver all such documents and instruments as
     are reasonably necessary to transfer, and shall be deemed to have
     transferred and to have represented and warranted to MTVNS that it has
     transferred, good title to the Partnership Interests being sold to MTVNS,
     free and clear of all liens, other than those created by this Agreement or
     any Additional Agreement or created by MTVNS.

                   (iii)   Subject to Section 8.06(b), the obligation of MTVNS
                                      ---------------
and Tune to proceed with the Put/Call Closing shall be conditioned upon, and the
scheduled Put Closing Date or Call Closing Date, as the case may be, shall be
extended to 10 days following the last to occur of, the receipt of all material
governmental and regulatory consents, approvals or waivers that may be required
in connection with the purchase and sale of the Tune Partnership Interest (other
than any such consent or approval which has, if permitted by law, been waived by
MTVNS or Tune, as applicable, in which case MTVNS or Tune, as applicable, shall
indemnify and hold harmless Tune or MTVNS, as applicable, for all losses,
damages and expenses incurred by Tune or MTVNS, as applicable, their respective
Affiliates and their respective partners, shareholders, members, directors,
officers, employees and agents as a result of MTVNS' or Tune's (as the case may
be) decision to so proceed with the Put/Call Closing pursuant to an instrument
reasonably satisfactory to Tune or MTVNS, as applicable); provided, however,
                                                          --------- --------
that Tune shall not be obligated to sell, and MTVNS shall not be obligated to
purchase, such interest to the extent that proceeding in such transaction would
violate any law, rule or regulation applicable to TCI Music or MTVN or their
respective Controlled Affiliates or their respective businesses or assets, or
subject any of the foregoing to any injunction, or other equitable remedy of any
court or government entity. MTVNS and Tune shall each use all reasonable efforts
in cooperation with each other promptly to make all filings, give all notices
and secure all consents, approvals and waivers that may be required in
connection with the purchase and sale of the Tune Partnership Interests.

                   (iv)    Upon consummation of the purchase of all of the Tune
     Partnership Interest, Tune shall cease to be a Partner or to have any
     right, title or interest in or to the Partnership.

                                   ARTICLE I

               REORGANIZATION OF PARTNERSHIP TO CORPORATE FORM;
               ------------------------------------------------
                            INITIAL PUBLIC OFFERING
                            -----------------------

     Section 1.1.  Reorganization in Corporate Form.
                   --------------------------------

          (a)  The parties hereto agree to take such steps as may be reasonably
necessary to cause the Partnership to be reorganized as, or to cause its assets
and liabilities to be contributed to, a Delaware corporation (which will be
wholly-owned by the Partnership or the Partners prior to the IPO, as defined
below), in connection with the IPO or, if the Chief Executive Officer of the
Partnership determines in good faith that it is appropriate, in advance of the
IPO in order to avoid adverse tax consequences to the Partners (the
"Reorganization").  The Partners acknowledge that the Partnership will not be
 --------------
the entity to go public in the IPO unless agreed by all Partners.  For any
period during which Newco is not a wholly-owned subsidiary of the Partnership,
the parties shall enter into or cause their respective Controlled Affiliates to
enter into a stockholders agreement (the "Newco Stockholders Agreement"), which
                                          ----------------------------
shall provide that the parties and their respective Controlled Affiliates, as
applicable, shall continue to be bound by, and entitled to the benefits of, the
following provisions of the Partnership Agreement, mutatis mutandis, subject to
                                                   ------- --------
the terms and conditions and applicable time periods contained therein (except
to the extent otherwise provided herein): provisions relating to capital
contributions (Section 3.03); provisions relating to management and governance
(Article VI (including Sections 6.10 and 6.11)); restrictions on transfer
(Section 8.01); rights of first offer (Section 8.04); "tag along/drag along"
rights (Section 8.05); provisions relating to Tune's audit rights with respect
to Related Party Transactions (Article XI); preemptive rights (Section 12.02);
put and call rights (Section 12.03); and restrictions on competition (Article
XIV); provided, however, that the provisions relating to capital contributions
      --------  -------
and to management and governance shall cease to apply upon the consummation of
the IPO; and provided further that the provisions with respect to the right of
             -------- -------
first offer shall be modified as follows:  (x) in the event that Newco has
consummated an IPO and the Shares (as defined below) are publicly traded, (i)
the two 30-day periods shall be reduced to one period of five Business Days, to
run concurrently (i.e., a Tune Partner must notify MTVN of its intention to sell
                  ----
five days before selling, and MTVN has through the fifth day to make an offer),
(ii) any offer to be made by MTVNS or its designee must be made at the then-
current market price (i.e. at the opening of business on the date such offer is
                      ----
made) or higher, (iii) the 180-day period shall be reduced to five Business Days
and (iv) the price at and terms on which the Shares may be sold during such five
Business Day period shall be the market price and market terms (including terms
relating to block sales) at the time of sale; (y) such right of first offer
shall not apply to any sale by a Tune Partner or a Permitted Transferee of a
Tune Partner pursuant to any exercise of its registration rights granted
pursuant to this Agreement (including any such public sale occurring following
the exercise of such registration rights where Newco determines such
registration rights are not available (and therefore refuses to register such
Shares) because of the type of sale contemplated (for example, because such
Shares can be sold pursuant to Rule 144) or where Newco elects not to register
such Shares because of events related to Newco (for example, where Newco
suspends its obligation to register such

                                       2
<PAGE>

shares pursuant to Article III of this Agreement); and (z) in the event of a
sale to MTVNS or its designee pursuant to the right of first offer where a Tune
Partner had initially proposed a public market sale, the 180-day period for
which the closing may be suspended will be reduced to a 20 day period, and the
90 day period within which a designated substitute purchaser is required to
close a sale shall be reduced to 60 days). The parties hereto agree to cause
Newco, promptly, upon its organization, to agree to be bound by this Agreement
as if it were a party hereto. The certificate of incorporation and bylaws of
Newco and the Newco Stockholders Agreement are referred to as the "Newco
                                                                   -----
Organizational Documents".
- - ------------------------

          (b)  The parties hereto further agree that, upon the effectiveness of
the Reorganization and provided that (i) neither TCI Music nor any of its
Controlled Affiliates is then in material default under this Agreement, the
Partnership Agreement or the Additional Agreements, (ii) the Tune Partners
beneficially own at least 5% of the outstanding Shares (as defined below)
(excluding any Shares issued or granted in any transaction or transactions with
respect to which TCI Music had no preemptive rights pursuant to any provision
comparable to Section 12.02 of the Partnership Agreement (or where the
Partnership Interests in respect of which such Shares were issued or granted
were originally issued or granted in a transaction with respect to which the
Tune Partners did not have preemptive rights pursuant to Section 12.02 of the
Partnership Agreement)), and (iii) none of the Tune Partners has Disposed of any
Partnership Interests or Shares to any Person that is not a Permitted
Transferee, each party shall take such steps as are reasonably necessary
(including causing such party's director designees to take such actions as are
necessary) to nominate for election and to vote all Shares of Newco beneficially
owned by such party in favor of the election of one designee of TCI Music as a
member of the Board of Directors of Newco.

     Section 1.2.  The Initial Public Offering.
                   ---------------------------

          (a)  The parties hereto intend that Newco conduct an initial
registered public offering of the common stock of Newco (the "Shares") no later
                                                              ------
than the Offering Expiration Date which results in the Shares being publicly
traded and listed on the Nasdaq Stock Market or a national securities exchange
(the "IPO"). As used herein the term "Shares" includes all shares of common
      ---                             ------
stock of Newco and any other shares of capital stock of Newco issued in respect
of such shares as a result of stock splits, stock dividends, reclassification,
recapitalizations, mergers, consolidations or similar events. References in this
Agreement to amounts or percentages of Shares as of or on any particular date
shall be deemed to refer to amounts or percentages after giving effect to any
applicable events contemplated by the preceding sentence. References herein to
Shares acquired in a transaction with respect to which TCI Music did not have
preemptive rights pursuant to the provisions of the Newco Stockholders Agreement
comparable to Section 12.02 of the Partnership Agreement shall include Shares
issued in respect of Partnership Interests which were acquired by the applicable
Person in a transaction with respect to which the Tune Partners did not have
preemptive rights under Section 12.02 of the Partnership Agreement.

<PAGE>

          (b)  If the IPO is consummated while Newco is owned by the
Partnership, the Partnership shall be liquidated immediately following or
contemporaneously with the IPO, and, provided that neither TCI Music nor any of
its Controlled Affiliates is in material default of its obligations under this
Agreement, the Partnership Agreement or the Additional Agreements, the number of
Shares distributed to the Tune Partners in respect of their interests in the
Partnership shall be increased, if necessary (without the payment of any
additional consideration other than the payment of the par value for any newly-
issued Shares), above the number that would otherwise be so distributed so that
the number of Shares so distributed shall have an aggregate value (with each
such Share valued for this purpose at the price to the public listed on the
cover page of the final prospectus delivered in connection with such IPO) equal
to at least the Target Value (as reduced proportionally to reflect any
Disposition by any Tune Partner of any portion of the Tune Partnership Interest
prior to the IPO other than to a Permitted Transferee); provided, however, that
                                                        --------  -------
the number of Shares distributed to the Tune Partners shall not exceed 15% (or
such lesser percentage which equals 150% of the Percentage Interest of the Tune
Partners immediately prior to the IPO other than to a Permitted Transferee) of
the total number of Shares outstanding immediately prior to the IPO.

          (c)  If (i) Newco consummates an IPO (except under the circumstances
described in Section 1.2(b) above) and (ii) the aggregate value of the Shares
held by the Tune Partners (with each Share valued for such purpose at the price
to the public listed on the cover page of the final prospectus delivered in
connection with such IPO) at the time of such IPO is less than the Target Value
(as reduced proportionally to reflect any Disposition by any Tune Partner of any
portion of the Tune Partnership Interest or of any Shares prior to the IPO other
than to a Permitted Transferee) and provided that neither TCI Music nor any of
its Controlled Affiliates is in material default of their obligations under this
Agreement, the Partnership Agreement or the Additional Agreements, then the
parties hereto shall cause Newco to promptly issue to the Tune Partners (without
the payment of additional consideration, other than the payment of the par value
for the Shares) such additional number of Shares as is required to cause the
aggregate value of Shares (valued as provided above) held by the Tune Partners
to equal the Target Value (as reduced proportionally to reflect any Disposition
by any Tune Partner of any portion of the Tune Partnership Interest or of any
Shares prior to the IPO other than to a Permitted Transferee); provided,
                                                               --------
however, that the number of Shares to be held by the Tune Partners after such
- - -------
issuance shall in no event exceed 15% (or such lesser percentage which equals
150% of the percentage of outstanding Shares held by the Tune Partners
immediately prior to the IPO) of the total Shares outstanding immediately prior
to the IPO (but after the issuance of such additional Shares).

     Section 1.3.  No Public Offering.
                   ------------------

          (a)  In the event that Newco has been formed but has not consummated
the IPO on or before the Offering Expiration Date and the Tune Partners then
hold Shares rather than Partnership Interests, TCI Music shall be entitled to
request that the Private Share Valuation (as defined below) as of the Offering
Expiration Date of the Shares held by the Tune Partners be determined.  Such
election shall be made by written notice to MTVN and Newco delivered

                                       4
<PAGE>

within six months after the Offering Expiration Date. If the Private Share
Valuation as of the Offering Expiration Date of the Shares held by the Tune
Partners is determined to be less than the Target Value and provided that
neither TCI Music nor any of its Controlled Affiliates is in material default of
their obligations under this Agreement, the Partnership Agreement or the
Additional Agreements, then Newco shall promptly issue to the Tune Partners
(without the payment of additional consideration, other than the payment of the
par value for the Shares) such additional number of Shares as is required to
cause the aggregate Private Share Valuation of the Shares held by the Tune
Partners as of the Offering Expiration Date to equal the Target Value; provided,
                                                                       --------
however, that the number of Shares to be held by the Tune Partners after such
- - -------
issuance shall in no event exceed 15% (or such lesser percentage which equals
150% of the percentage of outstanding Shares held by the Tune Partners on the
Offering Expiration Date) of the then outstanding Shares; and provided, further,
                                                              --------  -------
however, that the Tune Partners may elect to defer receipt of such additional
- - -------
Shares (in such number as determined above) until the first to occur of the (x)
the IPO, (y) such date as the Tune Partners shall request such receipt or (z)
the first anniversary of the Offering Expiration Date.

          (b)  For purposes hereof, "Private Share Valuation" shall mean the
                                     -----------------------
amount determined pursuant to the following procedure, which determination shall
be final and binding on the parties hereto. Upon receipt by MTVN of the written
notice from TCI Music to MTVN and Newco provided for in Section 1.3(a) above,
MTVN and TCI Music shall attempt to mutually agree on the Fair Market Value as
of the Offering Expiration Date of the Shares held by the Tune Partners. If the
parties are unable to reach agreement within 60 days after such notice is
received by MTVN, each party shall, within 30 days thereafter, retain an
investment bank to determine the Fair Market Value as of the Offering Expiration
Date of the Shares held by the Tune Partners. If any party fails to retain an
investment bank within such 30-day period, the investment bank retained shall be
the sole investment bank to make such determination. Each investment bank (or in
the event either party fails to retain an investment bank, the sole investment
bank) shall submit its estimation of such Fair Market Value within 45 days from
the date of its selection. If the determinations of Fair Market Value as of the
Offering Expiration Date of the Shares held by the Tune Partners by the
investment banks differ by less than 10% of the average of the two
determinations, such Fair Market Value shall be the average of the two
determinations. If such determinations vary by more than 10% of the average of
such two determinations, the two investment banks shall promptly designate a
third investment bank which shall be unaffiliated with any of the first two
investment banks and shall not have had any significant affiliation with, or
engagement for, any of the parties hereto or any Affiliate of any of the parties
during the two years prior to its selection. The third investment bank shall
select one of the two determinations as the Fair Market Value as of the Offering
Expiration Date of the Shares held by the Tune Partners within 30 days from the
date of its selection. In determining the Private Share Valuation, the
investment bank or banks shall be instructed to assume the continuation of the
Promotion Agreement in accordance with its terms.

     Section 1.4.  Going Private.  In the event that, following the IPO, MTVN
                   -------------
(or a Controlled Affiliate of Viacom Inc.) engages or causes Newco to engage in
a "Rule 13e-3 transaction" (as such term is defined in Rule 13e-3 under the
Securities Exchange Act of 1934, as

                                       5
<PAGE>

amended (the "1934 Act")) with respect to Newco, MTVN (or such Controlled
              --------
Affiliate of Viacom Inc.) shall offer TCI Music and its Controlled Affiliates an
opportunity to continue their existing proportionate equity interest in Newco
vis-a-vis MTVN (or Viacom Inc. or a Controlled Affiliate of Viacom Inc.) by
participation in such Rule 13e-3 transaction with Viacom Inc. and its Controlled
Affiliates after such transaction on the same basis as Viacom Inc. and its
Controlled Affiliates.

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

     Section 2.1.  Guaranties.
                   ----------

          (a)  Each Guarantor (as defined below) hereby unconditionally and
irrevocably guarantees (this "Guaranty") to an Other Partner (as defined below),

performed by Box under the License Agreement dated as of the date hereof between
The Box Worldwide LLC and Box and the Box Holland Promissory Note dated as of
the date hereof from The Box Worldwide-Europe, B.V. to the Partnership (the
obligations under such License Agreement and such Promissory Note being referred
to as the "Box Obligations") (collectively, the "Guaranteed Obligations"), in
           ---------------                       ----------------------
the case of the obligations described in clauses (i) and (ii) when and as the
same shall become due under the Partnership Agreement and the Contribution
Agreements, as the case may be.

     As used in this Section 2.1, (i) the term "Guarantor" shall mean each of
                                                ---------
MTVN and TCI Music, (ii) the term "Related Partner" shall mean each of VLLC and
                                   ---------------
Imagine, with respect to MTVN as Guarantor, and each of SonicNet and Box, with
respect to TCI Music as Guarantor, and (iii) the term "Other Partner" shall
                                                       -------------
mean, with respect to MTVN, each of SonicNet and Box, and with respect to TCI
Music, each of VLLC and Imagine, and/or, in each case, any immediate or
subsequent successor to or transferee of the Partnership Interest (as such term
is defined in the Partnership Agreement) originally held by such person.

     Notwithstanding anything to the contrary in this Guaranty, (i) the terms
"Related Partner" and "Other Partner," respectively, shall not mean (x) any
 ---------------       -------------
transferee of the Partnership Interest of a Related Partner or Other Partner
(except to the extent that obligations of a Related Partner

                                       6
<PAGE>

under the Partnership Agreement expressly survive a transfer by the Other
Partner to a transferee other than a Permitted Transferee), as the case may be,
other than a Permitted Transferee or (y) any immediate or subsequent successor
to or transferee of the Partnership Interest of a transferee referred to in
clause (x), and (ii) a Guarantor shall not be deemed to have guaranteed hereby
any obligation (monetary or otherwise) of any such transferee or successor other
than a Permitted Transferee, and a Guaranty shall not inure to the benefit of
any such transferee or successor other than a Permitted Transferee.

          (b)  Each Guarantor shall not cause or suffer a Related Partner
voluntarily to institute any proceeding seeking to adjudicate a Related Partner
a bankrupt or insolvent, or seeking liquidation, winding up, reorganization,
arrangement, adjustment, protection, relief or composition of the Partner or its
debts under any law relating to bankruptcy, insolvency or relief of debtors, or
seeking the entry of an order for relief or the appointment of a receiver,
trustee or other similar official for it or for any part of its property, in
each case unless in connection with the institution by Guarantor itself of any
such proceeding; provided, however, that, without limitation of the other
                 --------  -------
provisions of this Guaranty, nothing in this Section 2.1(b) shall require a
Guarantor to provide any funds to a Related Partner for the payment or discharge
of the Partner's obligations.

          (c)  Each Guarantor waives any and all notices of the creation,
renewal, extension or accrual of any of the Guaranteed Obligations and notice or
proof of reliance by an Other Partner on this Guaranty or acceptance of this
Guaranty. The Guaranteed Obligations shall conclusively be deemed to have been
created, contracted or incurred in reliance on this Guaranty, and all dealings
between an Other Partner and/or its Affiliates, on the one hand, and a Related
Partner and/or its Affiliates, on the other hand, in connection with the
Partnership Agreement and the Contribution Agreements shall likewise
conclusively be presumed to have been had or consummated in reliance on this
Guaranty, and the LMA and the Box Obligations shall also conclusively be
presumed to have been entered into in reliance on this Guaranty. The Guarantor
also waives diligence, presentment, demand for payment, protest and notice of
nonpayment or dishonor and all other notices and demands whatsoever relating to
the Guaranteed Obligations or the requirement that the Partnership or an Other
Partner proceed first against a Related Partner or any other guarantor of the
Guaranteed Obligations or otherwise exhaust any right, power or remedy under the
Partnership Agreement or the Contribution Agreements, as the case may be, giving
rise to such Guaranteed Obligations before proceeding hereunder. The Guarantor
covenants that this Guaranty shall not be discharged except by complete payment
and performance of the Guaranteed Obligations.

          (d)  The obligations of each Guarantor hereunder shall constitute a
present and continuing guarantee of payment and not of collectability only,
shall be absolute and unconditional, shall not be subject to any counterclaim,
setoff, deduction or defense the Guarantor may have against an Other Partner, a
Related Partner, the Partnership or any other person (other than counterclaims,
setoffs, deductions or defenses available to the Related Partner under or in
respect of the Partnership Agreement, the Contribution Agreements, the LMA and
the Box Obligations, as the case may be), and shall remain in full force and
effect until all

                                       7
<PAGE>

Guaranteed Obligations have been satisfied and performed in full, without regard
to any event whatsoever (whether or not the Guarantor shall have any knowledge
or notice thereof or shall have consented thereto), including, without
limitation:

               (i)   any amendment or modification of or supplement to the
     Partnership Agreement, the Contribution Agreements, the LMA, the Box
     Obligations or this Guaranty, any assignment or transfer of any of the
     rights, obligations, duties or covenants of any party to the Partnership
     Agreement, the Contribution Agreements, the LMA, the Box Obligations or
     this Guaranty, any renewal or extension of time for the performance of any
     of the Guaranteed Obligations, or any furnishing or acceptance of security
     so furnished or accepted for any of the Guaranteed Obligations;

               (ii)  any waiver, consent, extension, forbearance, release or
     substitution of security or other action or inaction under or in respect of
     the Partnership Agreement, the Contribution Agreements, the LMA, the Box
     Obligations or this Guaranty, or any excise of, or failure to exercise, any
     right, remedy or power in respect hereof or thereof;

               (iii) any bankruptcy, insolvency, marshaling of assets and
     liabilities, arrangements, readjustment, composition, receivership,
     assignment for the benefit of creditors, liquidation or similar proceedings
     with respect to a Related Partner or Guarantor;

               (iv)  the dissolution, sale or other disposition of all or
     substantially all of the assets of a Related Partner, a Guarantor, an Other
     Partner or the Partnership; or

               (v)   any default by a Related Partner or Guarantor under, or any
     invalidity or any unenforceability of, or any misrepresentation by a
     Related Partner or Guarantor in, or any irregularity or other defect in,
     the Partnership Agreement, the Contribution Agreements, the LMA, the Box
     Obligations or this Guaranty or any other instrument or agreement.

     Any term of this Guaranty to the contrary notwithstanding, if at any time
any amount (constituting a Guaranteed Obligation) paid or payable by a Related
Partner is rescinded or must otherwise be restored or returned, whether upon or
as a result of the appointment of a custodian, receiver or trustee or similar
officer for a Related Partner or any substantial part of its assets, or the
insolvency, bankruptcy or reorganization of a Related Partner or otherwise, the
Guarantor's obligations hereunder with respect to such payment shall be
reinstated as though such payment had been due but not made at such time.

          (e)  Each Guarantor will not exercise any rights which it may have
acquired against a Related Partner by way of subrogation, by any payment made
hereunder or otherwise, or accept any payment on account of such subrogation
rights, unless and until all of the Guaranteed Obligations of the Related
Partner for which performance is then due have been fully satisfied.

          (f)  Each Guarantor may at any time elect to pay or otherwise perform
any Guaranteed Obligation, which shall operate (subject to the last sentence of
clause (d) of this Section 2.1) as a discharge and release of a Related Partner
from such Guaranteed Obligation to an Other Partner or the Partnership (but not
to the Guarantor as subrogee); provided, however, that no such election shall
                               --------  -------
release a Related Partner from any of its other Guaranteed Obligations.

          (g)  The obligations of each Guarantor hereunder with respect to
Guaranteed Obligations shall apply, in addition and not in limitation of the
obligations of the Guarantor with respect to a Related Partner, to each
immediate or subsequent successor to or transferee of the Partnership Interest
of the Partner who is a Permitted Transferee with the same force and effect as
would be the case if such successor or transferee had originally be named as a
"Related Partner" hereunder.

          (h)  Neither Guarantor may assign its rights or delegate its duties
hereunder, except to any entity into which it may be merged or with which it may
be consolidated or to which it may transfer all or substantially all of its
assets, without the prior written consent of each Other Partner.

          (i)  The Guaranty by each Guarantor is intended solely for the benefit
of, and shall inure to the benefit of and may be enforced solely by, each Other
Partner and its successors and permitted assigns under the Partnership Agreement
(including without limitation any successor of each Other Partner), and may not
be relied on, nor is it enforceable by, any other Person.

each Person holding an equity interest in the Tune Partners and it covenants and

                                  ARTICLE III

                              REGISTRATION RIGHTS
                              -------------------

     Section 3.1.  Demand Rights.
                   -------------

          (a)  The Tune Partners shall have the right, at any time after the
consummation of the IPO, upon written notice and subject to the provisions of
this Article III, to require Newco to prepare and file as soon as practicable
after receipt of such notice and use its reasonable best efforts to cause to
become effective as soon as practicable thereafter a registration statement (a
"Registration Statement") under the Securities Act of 1933, as amended (the
 ----------------------
"Securities Act"), with respect to the resale of all Shares requested by the
 --------------
Tune Partners to be so registered (a "Demand Registration"); provided, however,
                                      -------------------    --------  -------
that Newco shall not be required to violate the terms of any "lock-up" or
"standstill" provisions relating to any securities offering by it by which it
may be bound.

          (b)  Notwithstanding anything to the contrary contained herein, Newco
shall have no obligation to prepare, file and cause to become effective the
Registration Statement (i) unless the Shares to be registered pursuant to the
Registration Statement constitute at least 25% of the Shares beneficially owned
by the Tune Partners as of the date of the notice requesting such registration
or (ii) if Newco delivers to TCI Music an opinion of counsel to the effect that
all such Shares for which registration was requested may be sold in a single
transaction without registration under the Securities Act. Furthermore, Newco
shall not be obligated to prepare, file and cause to become effective
Registration Statements for more than two such registrations pursuant to this
Section 3.1.

                                       10
<PAGE>

          (c)  If the selling Tune Partner so elects, it may cause the public
offering or distribution of the Shares pursuant to a Demand Registration to be
pursuant to a firm commitment underwriting, the managing underwriter of which
shall be a nationally recognized investment banking firm selected by the selling
Tune Partner and approved by Newco (which approval shall not be unreasonably
withheld). Newco shall enter into the same underwriting agreement as shall the
selling Tune Partner, containing representations, warranties, indemnities, and
agreements reasonably acceptable to Newco and not substantially different from
those customarily made by an issuer in underwriting agreements with respect to
secondary distributions. If (i) a Demand Registration is for a firm commitment
underwritten public offering and the managing underwriter thereof determines in
good faith that the aggregate number of Shares to be offered thereby exceeds the
total number of Shares that may be successfully offered at an estimated initial
price per share to the public that is at least equal to the minimum initial
price per Share (which shall not be higher than the market price at the time of
designation) to the public that has been designated in writing at the time of
the notice referred to in Section 3.1(a) by the selling Tune Partner, and/or
(ii) a Demand Registration is delayed more than 30 days pursuant to Section
3.3(b) prior to being declared effective, and in either case no Shares are sold
pursuant to such Demand Registration, then the selling Tune Partner shall have
the right to reduce or withdraw its request for such registration by giving
written notice to the Company to such effect, in which event, in the case of a
withdrawal, such registration shall not be deemed to have occurred for purposes
of the last sentence of Section 3.1(b).

          (d)  The selling Tune Partners may elect to withdraw their Shares from
inclusion in a Demand Registration; provided that, except for a withdrawal
pursuant to the last sentence of Section 3.1(c), notwithstanding such
withdrawal, such registration shall be deemed to have occurred for the purposes
of the last sentence of Section 3.1(b), unless the selling Tune Partners pay
(pro rata, in proportion to the number of Shares requested by them to be
included in such registration) within 30 days after any such withdrawal, all of
the out-of-pocket expenses of Newco incurred in connection with such
registration.  Neither Newco nor any Person that is not a Tune Partner shall
participate in any Demand Registration unless the selling Tune Partners
otherwise agree.

          (e)  A Demand Registration shall not be deemed to have been effected
until such registration has been effective (and not subject to any stop order,
injunction or other order or requirement of the Securities and Exchange
Commission (the "SEC") or other Governmental Entity for any reason) for a period
of 150 days following the date on which such registration was declared
effective, or, if earlier, the date on which all Shares requested to be
registered thereunder have been sold.

          (f)  Newco shall not grant to any other Person the right to include
any other Shares in any Registration Statement filed pursuant to this Section
3.1.

<PAGE>

     Section 3.2.  Piggy-Back Rights.
                   -----------------

          (a)  For so long as the Tune Partners beneficially own at least 1% of
the Shares outstanding, each time that Newco intends to proceed with the actual
preparation and filing of a registration statement under the Securities Act for
its own account or the account of any member of the MTVN Stockholder Group in
connection with the proposed offer and sale (including in connection with the
IPO) for money of any securities of Newco (other than a registration statement
on Form S-4 or Form S-8 or any successor to either such form), Newco will give
at least 20 days written notice of its election to TCI Music. Upon the written
request of TCI Music to Newco given within 10 days after receipt of any such
notice from Newco, Newco will, except as herein provided, use its reasonable
best efforts to cause all Shares for which TCI Music has requested registration
to be included in such registration statement, all to the extent requisite to
permit the sale or other disposition by the Tune Partners of the Shares to be so
registered, with TCI Music paying any direct incremental expenses attributable
to the registration of such Shares; provided, however, that (i) nothing herein
                                    --------  -------
shall prevent Newco from, at any time, abandoning or delaying any such
registration initiated by it; (ii) if Newco determines not to proceed with a
registration after the registration statement has been filed with the SEC, Newco
shall complete the registration for the benefit of the Tune Partners if TCI
Music wishes to proceed with a public offering of such Shares and agrees, along
with any other selling shareholder also electing to proceed, to bear its pro
rata share of expenses reasonably incurred by Newco as the result of such
registration of such Shares after Newco has decided not to proceed; (iii) for
purposes of this sentence, the use by Newco of reasonable best efforts shall not
require Newco to materially reduce the amount or sale price of the securities it
proposes to distribute for its own account; and (iv) Newco shall not be required
to violate the terms of any "lock-up" or "standstill" provisions relating to any
securities offering by which it may be bound. If any registration pursuant to
this Section 3.2 shall be underwritten in whole or in part, (A) Newco may
require that the Shares requested for inclusion pursuant to this Section 3.2 be
included in the underwriting on the same terms and conditions as the Shares
otherwise being sold through the underwriters and (B) the selling Tune Partners
may elect, in writing not less than three Business Days prior to the effective
date of the registration statement filed in connection with such registration,
not to register their Shares in connection with such registration. No
registration effected under this Section 3.2 shall relieve Newco of its
obligation to effect Demand Registrations in accordance with Section 3.1.

          (b)  In connection with a registration under this Section 3.2, Newco
may enter into an underwriting agreement in such customary form as shall have
been negotiated and agreed to by Newco with the underwriter or underwriters
selected for such underwriting by Newco.  Notwithstanding any other provision of
this Section 3.2, if in the opinion of the managing underwriter the inclusion of
Shares owned by the Tune Partners in a registration statement would materially
reduce the amount or sale price of the other securities to be included in such
registration, Newco may reduce, to as low as zero, the number of Shares to be
included by the Tune Partners in the registration and underwriting under this
Section 3.2, to the extent necessary to cause inclusion of such Shares not to be
materially detrimental to the registration filed pursuant to this Section 3.2.

     Section 3.3.  General Provisions.
                   ------------------

          (a)  If and whenever Newco is required by the provisions of this
Article III to effect the registration of Shares owned by the Tune Partners
under the Securities Act, Newco will:

               (i)    subject to the terms and conditions of this Article III,
     as expeditiously as possible, prepare and file with the SEC a registration
     statement with respect to such Shares, and use its reasonable best efforts
     to cause such registration statement to become and remain effective for
     such period as may be reasonably necessary to effect the sale of such
     Shares, but in no event longer than 150 days;

               (ii)   prepare and file with the SEC such amendments to such
     registration statement and supplements to the prospectus contained therein
     as may be necessary to keep such registration statement effective for such
     period as may be reasonably necessary to effect the sale of such Shares,
     but in no event longer than 150 days;

               (iii)  furnish to TCI Music such reasonable number of copies of
     the registration statement, preliminary prospectus, final prospectus and
     such other documents as TCI Music may reasonably request in order to
     facilitate the public offering of such Shares;

               (iv)   prepare and promptly file with the SEC and promptly notify
     TCI Music of the filing of such amendment or supplement to such
     registration statement or prospectus as may be necessary to correct any
     statements or omission if, at the time when a prospectus relating to such
     Shares is required to be delivered under the Securities Act, any event
     shall have occurred as the result of which any such prospectus or any other
     prospectus as then in effect would include an untrue statement of a
     material fact or omit to state any material fact necessary to make the
     statements therein, in the light of the circumstances in which they were
     made, not misleading and promptly provide to TCI Music sufficient copies of
     such amended or supplemented prospectus so that it can be delivered to the
     purchasers of the Shares as required by the Securities Act and the
     regulations thereunder; and

               (v)    advise TCI Music, promptly after it shall receive notice
     or obtain knowledge thereof, of the issuance of any stop order by the SEC
     suspending the effectiveness of such registration statement or the
     initiation or threatening of any proceeding for that purpose, promptly use
     its reasonable best efforts to prevent the issuance of any stop order or to
     obtain its withdrawal if such stop order should be issued and promptly
     notify Tune of the forbearance, lifting or withdrawal of such stop order or
     proceeding.

               (vi)   notify TCI Music, (A) when a registration statement
     becomes effective, (B) when the filing of a post-effective amendment to a
     registration statement or

                                       13
<PAGE>

     supplement to a prospectus is required, when the same is filed, and in the
     case of a post-effective amendment, when the same becomes effective, and
     (C) of any request by the SEC for any amendment of or supplement to a
     Registration Statement or any prospectus relating thereto or for additional
     information;

               (vii)  register or qualify the Shares covered by a Registration
     Statement under the securities or blue sky laws of such jurisdictions in
     the United States as the selling Tune Partners shall reasonably request,
     and do any and all other acts and things which may be necessary to enable
     each Tune Partner whose Shares are covered by such Registration Statement
     to consummate the disposition in such jurisdictions of such Shares;
     provided, however, that Newco shall in no event be required to qualify to
     --------  -------
     do business as a foreign corporation or a dealer in any jurisdiction where
     it is not so qualified, to conform its capitalization or the composition of
     its assets at the time to the securities or blue sky laws of such
     jurisdiction, to execute or file any general consent to service of process
     under the laws of any jurisdiction, to take any action that would subject
     it to service of process in suits other than those arising out of the offer
     and sale of the Shares covered by such Registration Statement, or to
     subject itself to taxation in any jurisdiction where it has not theretofore
     done so; and

               (viii) cause the Shares covered by a Registration Statement to
     be listed on the principal exchange or exchanges or qualified for trading
     on the principal over the counter market on which the common stock of Newco
     is then listed or traded upon the sale of such Shares pursuant to such
     Registration Statement.

               (ix)   at least three Business Days prior to filing a
     registration statement or any amendment or supplement thereto, furnish to
     TCI Music and each underwriter, if any, of the Shares covered by such
     registration statement copies of such registration statement, amendment or
     supplement as proposed to be filed (excluding documents to be incorporated
     by reference therein) which registration statement, amendment or supplement
     will be subject to reasonable review and comments by TCI Music and such
     underwriter insofar as such documents relate to TCI Music or its Controlled
     Affiliates or such underwriter (and their respective attorneys) during such
     three-Business Day period, and Newco will not file any registration
     statement, any prospectus or any amendment or supplement thereto containing
     any statements with respect to TCI Music or its Controlled Affiliates to
     which TCI Music shall reasonably object in writing.

               (x)    furnish to TCI Music and the underwriter, if any, such
     number of copies of such registration statement, each amendment and
     supplement thereto (in each case including all exhibits thereto and
     documents incorporated by reference therein), the prospectus included in
     such registration statement (including each preliminary prospectus) and
     such other documents as TCI Music or such underwriter may reasonably
     request in order to facilitate the disposition of the Shares.

                                       14
<PAGE>

               (xi)   make available for inspection by TCI Music, any
     underwriter participating in any disposition pursuant to such registration
     statement and any attorney, accountant or other professional retained by
     TCI Music or such underwriter (collectively, the "Inspectors"), all
                                                       ----------
     financial and other records, pertinent corporate documents and properties
     of Newco (collectively, the "Records") as shall be reasonably necessary to
                                  -------
     enable them to exercise their due diligence responsibility, so long as such
     Inspectors execute a confidentiality agreement with respect thereto in form
     and substance reasonably satisfactory to Newco, and cause Newco's officers,
     directors and employees to supply all information reasonably requested by
     any Inspectors in connection with such registration statement.

               (xii)  furnish to TCI Music and to each underwriter, if any, a
     signed counterpart of (i) an opinion or opinions of counsel to Newco
     addressed to TCI Music and such underwriter on which opinion both TCI Music
     and such underwriter are entitled to rely and (ii) a comfort letter or
     comfort letters from Newco's independent public accountants, each in
     customary form and covering such matters of the type customarily covered by
     opinions or comfort letters, as the case may be, as TCI Music or the
     managing underwriter therefor reasonably requests.

               (xiii) make available to its security holders, as soon as
     reasonably practicable, an earnings statement covering a period of 12
     months, beginning within three months after the effective date of the
     registration statement, which earnings statement shall satisfy the
     provisions of Section 11(a) of the Securities Act.

TCI Music, upon receipt of any notice from Newco of the happening of any event
of the kind described in paragraph (iv) or (v) above, will forthwith
discontinue, and cause its Affiliates to discontinue, disposition of the Shares
until TCI Music's receipt of the copies of the supplemented or amended
prospectus contemplated by paragraph (iv) above or until it is advised in
writing by Newco that the use of the prospectus may be resumed and has received
copies of any additional or supplemental filings which are incorporated by
reference in the prospectus.  If so directed by Newco, TCI Music will deliver to
Newco or destroy all copies, other than permanent file copies then in the
possession of TCI Music or its Affiliates, of the prospectus required to be
supplemented or amended.

          (b)  Notwithstanding anything to the contrary in this Agreement, if at
any time after the filing of a registration statement (i) in the case of any
registration statement for a firm commitment underwritten offering of Shares,
before it is declared effective by the SEC, or (ii) in the case of any other
registration statement, before or after it is declared effective by the SEC,
Newco determines, in its reasonable good faith business judgment, that such
registration and the offering of Shares covered by such registration would
interfere with or otherwise adversely affect any financing, acquisition,
corporate reorganization or other material transaction or development involving
Newco or any of its Controlled Affiliates or require Newco to disclose material
matters regarding itself or such Controlled Affiliates that otherwise would not
be required to be disclosed at such time, then Newco may require the suspension
of the distribution of any Shares (a

                                       15
<PAGE>

"Blackout Period") by giving notice to TCI Music. Any such notice need not
- - ----------------
specify the reasons for such suspension if Newco determines, in its reasonable
good faith business judgment, that doing so would interfere with or adversely
affect such transaction or development or would result in the disclosure of
material nonpublic information. In the event that such notice is given, then
until Newco has determined, in its reasonable good faith business judgment, that
such registration and distribution would no longer materially interfere with the
matters described in the preceding sentence and has given notice thereof to TCI
Music, Newco's obligations under this Article III will be suspended, provided
that such suspension shall not exceed the first to occur of (x) the filing of
Newco's next SEC filing and (y) 90 days. Newco shall extend the period of time
Newco is required to maintain effective any registration statement required
pursuant to clauses (i) and (ii) of paragraph (a) hereof by a length of time
equal to the aggregate length of the Blackout Periods. In the event of any
suspension of a registration pursuant to this Section 3.3(b), the selling Tune
Partners shall be entitled to withdraw from such registration upon written
notice to Newco.

          (c)  Newco's obligations to Tune under this Article III will be
conditioned on compliance with the following:

               (i)    TCI Music and its Affiliates will cooperate with Newco in
     connection with the preparation of the applicable registration statement,
     and for so long as Newco is obligated to keep such registration statement
     effective, TCI Music and its Affiliates will provide to Newco, in writing
     in a timely manner, for use in such registration statement (and expressly
     identified in writing as such), all information regarding TCI Music and its
     Affiliates and such other information as may be required by applicable law
     to enable Newco to prepare such registration statement and the related
     prospectus covering the applicable Shares owned by the selling Tune
     Partners and to maintain the currency and effectiveness thereof, so long as
     Newco executes a confidentiality agreement in form and substance reasonably
     satisfactory to TCI Music in the event any Confidential Information is
     requested by Newco;

               (ii)   TCI Music and its Affiliates will permit Newco and its
     representatives and agents to examine such documents and records and will
     supply in a timely manner any information as they may reasonably request in
     connection with the offering or other distribution of Shares by the Tune
     Partners;

               (iii)  TCI Music and its Affiliates will enter into such
     agreements with Newco and any broker-dealer or similar securities industry
     professional containing representations, warranties, indemnities and
     agreements as are customarily entered into and made by a seller of
     securities and such seller's controlling shareholders with respect to
     secondary distributions under similar circumstances;

               (iv)   during such time as TCI Music and its Affiliates may be
     engaged in a distribution of the Shares, TCI Music and its Affiliates will
     comply with all applicable laws, including Regulation M promulgated under
     the 1934 Act, and, to the

                                       16
<PAGE>

     extent required by such laws, will, among other things: (A) not engage in
     any stabilization activity in connection with the securities of Newco in
     contravention of such rules; (B) distribute the Shares acquired by it
     solely in the manner described in the applicable registration statement;
     (C) if required by applicable law, rules or regulations, cause to be
     furnished to each agent or broker-dealer to or through whom such Shares may
     be offered, or to the offeree if an offer is made directly by TCI Music and
     its Affiliates, such copies of the applicable prospectus (as amended and
     supplemented to such date) and documents incorporated by reference therein
     as may be required by such agent, broker-dealer or offeree, provided that
     Newco shall provide TCI Music with an adequate number of copies thereof;
     and (D) not bid for or purchase any securities of Newco; and

               (v)    on notice from Newco of the happening of any of the events
     specified in Section 3.3(a)(iv) or (v), or that, as set forth in Section
     3.3(b), requires the suspension by TCI Music and its Affiliates of the
     distribution of any of the Shares owned by the Tune Partners, then TCI
     Music and its Affiliates will cease offering or distributing the Shares
     owned by the Tune Partners until the offering and distribution of the
     Shares owned by the Tune Partners may recommence in accordance with the
     terms hereof and applicable law.

          (d)  Except as otherwise provided with respect to registrations
terminated by Newco, Newco shall bear the following fees, costs and expenses in
connection with its obligations under this Article III: all registration, filing
fees, printing expenses, all internal Newco expenses, the premiums and other
costs of policies of insurance against liability arising out of the public
offering, and all legal fees and disbursements and other expenses of complying
with state securities or blue sky laws of any jurisdiction in which Shares to be

and accountants for TCI Music and its Affiliates, underwriting discounts and
commissions and transfer taxes for TCI Music and its Affiliates and other direct
selling expenses incurred by TCI Music and its Affiliates not expressly included
above shall be borne by TCI Music and its Affiliates.

          (e)  Newco shall indemnify and hold harmless the selling Tune
Partners, and each Person, if any, who controls the selling Tune Partners within
the meaning of the Securities Act, from and against any and all claims, losses,
damages, liabilities, costs and expenses to which the selling Tune Partners or
any such controlling Person may become subject under the Securities Act or
otherwise, insofar as such claims, losses, damages, liabilities, costs or
expenses arise out of or are based on any untrue statement or alleged untrue
statement of any material fact contained in any registration statement filed by
Newco pursuant to this Article III which relates to Shares owned by the selling
Tune Partners, any 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 therein, in light of the circumstances in which they were made,
not misleading, except insofar as any such claim, loss, damage, liability, costs
or expense arises out of or is based upon an untrue statement or alleged untrue
statement or omission or alleged omission so made in conformity with information
furnished by TCI Music or its Affiliates or such controlling Person

                                       17
<PAGE>

specifically for inclusion in such registration statement; provided, however,
                                                           -----------------
that the foregoing indemnity is subject to the condition that, insofar as it
relates to any untrue statement or alleged untrue statement, omission or alleged
omission made in a preliminary prospectus but eliminated or remedied in a
prospectus, such indemnity agreement shall not inure to the benefit of the
selling Tune Partner or any Person who controls the selling Tune Partner if (A)
Newco complied with all of its notification and delivery obligations as provided
herein, (B) such claim, loss, damage, liability, cost or expense relates to the
matter so eliminated or remedied in the final prospectus and (C) the selling
Tune Partner or its Affiliates failed to deliver a copy of the prospectus at or
prior to the time such action is required by the Securities Act; provided,
                                                                 --------
further, that the foregoing indemnity is also subject to the condition that,
- - -------
insofar as it relates to any untrue statement or alleged untrue statement,
omission or alleged omission made in a prospectus attributable solely to facts
or events which occur after the effective date of the registration statement,
which untrue statement or alleged untrue statement, omission or alleged omission
is eliminated or completely remedied in an amendment or supplement to the
prospectus, such indemnity agreement shall not inure to the benefit of the
selling Tune Partner or any Person who control the selling Tune Partner or any
of its Affiliates, if, having previously been furnished by or on behalf of Newco
with copies of the prospectus as so amended or supplemented, in lieu thereof the
selling Tune Partner or its Affiliates delivered the prospectus without such
amendment or supplement.

          (f)  TCI Music shall indemnify and hold harmless Newco and any
underwriter (as defined in the Securities Act) for Newco, and each Person, if
any, who controls the Newco or such underwriter within the meaning of the
Securities Act from and against any claims, losses, damages, liabilities, costs
or expenses to which Newco or any such underwriter or controlling Person may
become subject under the Securities Act or otherwise, insofar as such claims,
losses, damages, liabilities, costs or expenses are caused by any untrue or
alleged untrue statement of any material fact contained in any registration
statement filed by Newco pursuant to this Article III which relates to Shares
owned by any Tune Partner or any of its Affiliates, any prospectus contained
therein or any amendment or supplement thereto, and arise out of or are based
upon the omission or the 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, in each case
to the extent, but only to the extent, that such untrue statement or alleged
untrue statement or omission or alleged omission was so made in reliance upon
and in strict conformity with written information furnished by TCI Music or its
Affiliates specifically for inclusion in such registration statement, prospectus
or amendment or supplement thereto).

          (g)  Except to the extent otherwise provided in this Section 3.3(g), a
party obligated to provide indemnification under Section 3.3(e) or (f) shall
reimburse each party entitled to such indemnification the costs of investigating
and defending any claim, loss, damage, liability, cost or expense giving rise to
such indemnification obligation.  Promptly after receipt by an indemnified party
pursuant to the provisions of paragraph (e) and (f)  of this Section 3.3 of
notice of commencement of any action involving the subject matter of the
foregoing indemnity provisions, such indemnified party will, if a claim thereof
is to be made against the indemnifying party pursuant to the provisions of said
paragraph (e) and (f) promptly notify the indemnifying

                                       18
<PAGE>

party of the commencement thereof, but the omission to so notify the
indemnifying party will not relieve it from any liability which it may have to
any indemnified party, except to the extent that the indemnifying party is
materially prejudiced by the failure to give such prompt notice. If such action
is brought against any indemnified party and it notifies the indemnifying party
of the commencement thereof, the indemnifying party shall have the right to
participate therein, and, to the extent that it may wish, jointly with any other
indemnifying party similarly notified, to assume the defense thereof so long as
it agrees to accept full responsibility to indemnify and hold harmless the
indemnified party in accordance herewith in respect of such action. After notice
from the indemnifying party to such indemnified party of its election so to
assume the defense thereof, the indemnifying party will not be liable to such
indemnified party pursuant to the provisions of said paragraph (e) and (f) for
any legal or other expense subsequently incurred by such indemnified party in
connection with the defense thereof other than reasonable costs of
investigation, unless (i) the indemnified party shall have been advised by its
counsel that use of the same counsel to represent both the indemnifying party
and the indemnified party would present a conflict of interest (which shall be
deemed to include any case where there may be a legal defense or claim available
to the indemnified party which is different from or additional to those
available to the indemnifying party) or (ii) the indemnifying party shall fail
vigorously to defend or prosecute such claim or demand within a reasonable time,
in which case the fees of counsel for the indemnified party shall be for the
account of the indemnifying party and the indemnifying party shall not have the
right to direct the defense of such action on behalf of the indemnified party.
The indemnifying party shall not be liable for any settlement of any proceeding
effected without its written consent but if settled with such consent, or if
there be a final judgment for the plaintiff, the indemnifying party shall
indemnify and hold harmless such indemnified parties from and against any loss
or liability (to the extent stated above) by reason of such settlement or
judgment. No indemnifying party shall, without the prior written consent of the
indemnified party, effect any settlement of any pending or threatened proceeding
in respect of which any indemnified party is or could have been a party and
indemnity could have been sought hereunder by such indemnified party, unless
such settlement includes an unconditional release of such indemnified party from
all liability arising out of such proceeding.

          (h)  The registration rights granted to TCI Music and its Controlled
Affiliates pursuant to this Article III are not assignable, except to the extent
any Partnership Interests or Shares are Disposed of to a Permitted Transferee or
other Controlled Affiliate in accordance with the terms of the Partnership
Agreement, the Newco Stockholder Agreement and/or this Agreement.  Any
assignment not permitted hereunder shall be null and void ab initio.

          (i)  If the indemnification provided for under Sections 3.3(e) or (f),
as applicable, is unavailable to or insufficient to hold the indemnified party
harmless under such Section in respect of any claim, loss, damage, liability,
cost or expense referred to therein (a "Liability") for any reason other than as
                                        ---------
specified therein, then the indemnifying party shall contribute to the amount
paid or payable by such indemnified party as a result of such claims, losses,
damages, liabilities, costs or expenses (i) in such proportion as is appropriate
to reflect the relative benefits received by the indemnifying party on the one
hand and such indemnified party on the other from the subject offering or
distribution or (ii) if the allocation provided by clause (i)

                                       19
<PAGE>

of this sentence is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i)
of this sentence but also the relative fault of the indemnifying party on the
one hand and such indemnified party on the other in connection with the
statements or omissions which resulted in such Liability as well as any other
relevant equitable considerations. The relative benefits received by the
indemnifying party on the one hand and the indemnified party on the other hand
shall be deemed to be in the same proportion as the net proceeds of the offering
or other distribution (after deducting expenses) received by the indemnifying
party bears to the net proceeds of the offering or other distribution (after
deducting expenses) received by the indemnified party. The relative fault shall
be determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by (or omitted to be supplied
by) Newco or the selling Tune Partners, the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission, the relative benefits received by each party from the sale of the
Shares and any other equitable considerations appropriate under the
circumstances. The amount paid or payable by an indemnified party as a result of
the Liability referred to above in this Section 3.3(i) shall be deemed to
include any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating or defending any such action or claim. No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

          (j)  Notwithstanding anything herein to the contrary, the parties
agree that the obligations and liability of the selling Tune Partners with
respect to any registration in which any Tune Partner participates pursuant to
Section 3.1 or 3.2 whether from indemnification pursuant to Section 3.3(f),
contribution pursuant to Section 3.3(i), or otherwise shall not in any event
exceed, in the aggregate, the amount of net proceeds received by such selling
Tune Partner from the sale of the Shares sold by such Tune Partner in such
registration.

applicable Controlled Affiliate to, divest it, unless (i) the Board of Directors
of SonicNet, Box, Liberty or TCI Music or such Controlled Affiliate shall have
been advised by outside counsel that the approval by such Board of such sale to

breach by such directors of their fiduciary duties owed to third parties or
stockholders other than stockholders of TCI Music or its parent entities, (ii)
such Divestiture would violate the provisions of any contract to which SonicNet,
Box, Liberty, TCI Music or such Controlled Affiliate is a party (other than
contracts entered into with a primary purpose referred to in the last sentence
of Section 4.2(c)), or (iii) such Divestiture would trigger any tax liability
for SonicNet, Box, Liberty or TCI Music or such Controlled Affiliate which is
material to SonicNet, Box, Liberty or TCI Music and would otherwise not be
triggered; provided, however, that in the event of the occurrence of any of the
           --------  -------
circumstances referred to in clauses (i)-(iii) above, such obligation to make a
Divestiture shall arise at such subsequent time during the restricted period (as
set forth in Section 4.2(a) or (b) as applicable) applicable hereto, if any, as
such potential breach of fiduciary duty or potential breach of contract or such
adverse tax consequence may be reasonably avoided.

     Section 4.3.  Exclusivity

business or assets; provided that this provision shall not apply to (i) any
children's services, including children's music services regardless of the means
of distribution of such services; (ii) the delivery of content purely ancillary
to a business that is not the Business, provided that the ancillary content that
may be delivered relates solely to MTVN and its operations; (iii) investment or
acquisitions of less than 3% (and, after the third anniversary of the Closing
Date, 25%) of the outstanding equity interest in any person or entity; (iv) the
acquisition or operation of any interest in a company or assets not principally

excess of 35% of the fair market value of the assets or revenues of such
acquired company or assets); or (v) any current or future business conducted by
any of the entities listed on Schedule I hereto to the extent such businesses
were not contributed to the Partnership by an MTVN Partner.

             (b)   For a period of five years from the Closing, MTVN will not
promote the Business as owned or operated by any Affiliate of MTVN (other than
the Partnership or Newco) on its cable television services except on commercial
terms.

             (c)   Notwithstanding the foregoing, the covenants set forth in
Section 4.3(a) and (b) shall be of no force or effect in the event that (i)

remedy to have such obligations or such Restrictive Covenant specifically
enforced by any court having jurisdiction, it being acknowledged and agreed that
any such breach or threatened breach will cause irreparable injury to the other

parties.  Nothing in this Section 4.5 shall be construed to limit the right of
any party hereto to collect money damages in the event of a breach of any such
obligation or Restrictive Covenant.  The parties hereto acknowledge that the
restrictions contained in Sections 2.3, 4.1, 4.2 and 4.3 are reasonable and

portion of the covenants or agreements contained in Sections 2.3, 4.1, 4.2 or
4.3, or the application thereof, is construed to be invalid or unenforceable,

regard to the invalid or unenforceable portions. If any such covenant or
agreement is held to be unenforceable in equity because of the area covered, the
duration thereof, or the scope thereof, then the court making such determination
will have the power to reduce the area and/or duration and/or limit the scope
thereof, and the covenant or agreement will then be enforceable in equity in its
reduced form.

                   ------------------
substantially all of Liberty's assets and businesses to (i) Liberty Media Group

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

          (a)       Following the IPO, the Tune Partnership Interest Value (as
otherwise defined in the Partnership Agreement or in the corresponding provision
of the Newco Stockholders Agreement) shall be the product of the Current Market
Price of one Share and the number of Shares that compromise the Tune Partnership
Interest.

     The "Current Market Price" for a security shall be the average of the
reported last sales prices for the 40 consecutive Trading Days before the date
of the applicable Put Notice or Call Notice, as the case may be.

     The reported last sales price of a security for each Trading Day shall be:

     (i)  the reported last sales price, regular way, as reported on the New
          York Stock Exchange Composite Tape; or

     (ii) if the security is not listed or admitted to trading on the New York
          Stock Exchange, on the National Market tier of The Nasdaq Stock
          Market; or

                                       30
<PAGE>

     (iii)  if the security is not listed or admitted to trading on the National
            Market tier of the Nasdaq Stock Market at such time, in the
            principal consolidated or composite transaction reporting system on
            the principal national securities exchange on which such security is
            listed or admitted to trading; or

     (iv)   if such security is not quoted on such National Market tier or any
            national securities exchange, the average of the highest bid and
            lowest asked prices on such day as reported on The Nasdaq Stock
            Market.

As used herein, the term "Trading Days" means a day on which the New York Stock
Exchange, each national securities exchange on which the security is listed and
The Nasdaq Stock Market are open for business, provided that if no sales of the
security takes place on such day on the relevant exchange or stock market
determined under the immediately preceding sentence, such day shall not be a
Trading Day.

            (b)     If TCI Music exercises its right to acquire an interest in
any business or assets pursuant to Section 4.3 of this Agreement, then such
interest shall be deemed to be part of the Tune Partnership Interest for all
purposes under Section 12.03 of the Partnership Agreement (and the corresponding
provision of the Newco Organizational Documents). If such interest is not in a
Publicly Traded security, its value shall be determined in the same manner as
provided for the determination of the Tune Partnership Interest Value in the
Partnership Agreement (or the corresponding provision of the Newco
Organizational Documents). If such interest is in a Publicly Traded security,
then its value shall be determined as provided in subsection (a) of this Section
5.16. A security shall be considered to be "Publicly Traded" as of any date if
on such date (i) the security is registered under Section 12(b) or 12(g) of the
1934 Act and (ii) the security is listed for trading on a national securities
exchange registered under the 1934 Act or traded in the over-the-counter market
and quoted on The Nasdaq Stock Market.
