benefits incurred on or after the Closing by Box-MTVN Employees or their
dependents. For purposes of this paragraph (n), a health care claim shall be
deemed to be incurred when the services giving rise to the claim are performed
and not when the employee is billed for such services or submits a claim for
benefits.

                  (o) TCI Music, SonicNet and Box shall be responsible for
providing any continuation of group health coverage to SonicNet LLC Employees or
Box-MTVN Employees or their dependents required by Section 4980B of the Code or

coverage to MTVN-Partnership Employees or their dependents required by COBRA

MTVN-Partnership Employee with respect to any period after the Closing; and MTVN

any Box-MTVN Employee with respect to any period after the Closing.

                  (q) Sections 3.1 (l) through (p) shall not apply to employees
of Box Italy or the Tune Subsidiaries other than SonicNet LLC or Box LLC.

                  (r) In the event that the Partnership or any of its Affiliates
terminates any employee of The Box Argentina S.A., it shall do so in accordance
with any procedures required by local Laws.

                  3.2. Rebates of Launch Fees. TCI Music will use its
commercially reasonable efforts to obtain rebates of all launch fees paid to any
cable system to which it or its subsidiaries may be entitled under the
applicable affiliation agreements relating to Box or its subsidiaries
("Rebates") . TCI Music will promptly pay over to the Partnership any Rebates
that it or any of its subsidiaries receive as a result of such efforts or
otherwise.

                  3.3. Interactive Music Channel. In the event that Liberty
assigns its 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
3.3. This Section 3.3 is not intended to obviate any of the obligations of
Liberty, TCI Music or their Controlled Affiliates under the provisions of
Section 4.2 of the Parent Agreement.

                  3.4.     The Telstra Agreement.

                                                                              19


                           (i) comply with the provisions of Section 10
(Confidentiality) of the Telstra Agreement;

                           (ii) designate and maintain one or more SonicNet
Sites, as defined in the Telstra Agreement, including a World Wide Web site
branded "Addicted to Noise" (the "Telstra SonicNet Sites"), similar in nature to
the currently existing SonicNet Sites with links to the TMPL Site (as defined in
the Telstra Agreement) site and an exclusive feed with respect to the content
developed for the Telstra SonicNet Sites for the TMPL Site similar to the feed
currently provided by the SonicNet Sites;

                           (iii) grant to SonicNet for it to grant to TMPL (as
defined in the Telstra Agreement) the exclusive license in respect of such
Telstra SonicNet Sites and Software (as defined in the Telstra Agreement)
contemplated by Section 3.1 of the Telstra Agreement, and provide to SonicNet
such services, products, notices and other items that SonicNet may require in
order to comply with all of SonicNet's covenants and obligations set forth in
the Telstra Agreement, and otherwise cooperate with and assist SonicNet in
complying, in a timely manner, with its covenants and obligations under the
Telstra Agreement, including, without limitation, its obligations under Section
6 thereof; and

                           (iv) refrain from taking any action following the
Closing, and during the term or any renewal by TMPL of the Telstra Agreement,
that would result in or cause a breach by SonicNet of its warranties to TMPL
contained in Section 9.1 of the Telstra Agreement.

                  (b) SonicNet shall not renew the Telstra Agreement, shall not
transfer any Trademarks (as defined in the Telstra Agreement), which Trademarks
are set forth on Schedule 3.4(b) hereto ("SonicNet Trademarks"), to anyone
(other than TMPL or their successors or assigns, except as consideration or
partial consideration for an early termination of the Telstra Agreement) 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
Telstra then after the expiration of the renewal term, all of SonicNet's rights
in and to the SonicNet Trademarks in the Territory (as defined in the Telstra
Agreement) , whether registered or unregistered, including the good will
associated therewith, shall, within 10 days after the expiration of the last of
SonicNet's obligations under the Telstra Agreement (including the conclusion of
any period following such termination during which SonicNet's activities in the
Territory are restricted or limited by the Telstra Agreement, be conveyed to
SonicNet LLC, free and clear of all Liens, and SonicNet will make
representations and warranties to SonicNet LLC comparable to those set 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.

                  3.5. The EMAP Agreements. With respect to the IP Rights
Agreement and the Share Purchase Agreement (capitalized terms used in this
Section 3.5 and not otherwise defined in this Section 3.5 or in this Agreement
shall have the meanings assigned to such terms in the EMAP Agreements):

                  (a) The Partnership shall, and shall cause its Controlled
Affiliates (all at the sole expense of Box) to provide to Box such Business
Information related to Box and access to Books and Records and title deeds of

operating costs and capital 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.

                  (b) The Partnership shall, and shall cause its applicable
Controlled Affiliates to, license to Box pursuant to the Box Holland License

extent necessary to enable Box or SonicNet or their respective subsidiaries to
meet their obligations under, and so as not to breach or be in breach of,

                                                                              21


the Telstra Agreement, the EMAP Agreements or the applicable Box Excluded

commercially reasonable efforts to negotiate with the other parties to the
Telstra Agreement and the EMAP Agreements for appropriate amendments to or
terminations of such agreement that would limit or eliminate the obligations of
Box and SonicNet and their applicable subsidiaries thereunder, provided that
none of TCI Music, Box nor SonicNet shall be obligated to make any material
expenditure in order to accomplish the same.

                  3.8. Cooperation for Financial Reporting. The Tune Entities
shall cooperate with the Partnership, or any successor, and shall provide the
Partnership, or any successor, access to all relevant financial information, to

financial reporting requirements of applicable law. Box shall provide the
Partnership with copies of all of its historical audited financial statements
and shall cause its auditors to cooperate with the Partnership in connection

this Agreement.

Partnership pursuant to the Imagine Contribution Agreement or the VLLC
Contribution Agreement), except for any such Contract providing for payments to
or by Imagine or VLLC, as the case may be, over the remaining term of such
Contracts of no more than $5,000 individually or $50,000 in the aggregate for
all such non-scheduled Contracts. Except as disclosed on Schedule 4.5(b), after
giving effect to the contribution to VLLC of the VLLC Assets (i) all such
Contracts are valid and binding on, and enforceable against, Imagine or VLLC, as
the case may be, in accordance with their terms, except as such enforceability

conveyance, reorganization or affecting creditors' rights generally and except
to the extent that injunctive or other equitable relief is within the discretion
of a court and each of such Contracts is, to the knowledge of Imagine or VLLC,
as the case may be, valid and binding on, and enforceable against the other
parties thereto, except as such enforceability may be limited by applicable laws
relating to bankruptcy, insolvency, fraudulent conveyance, reorganization or
affecting creditors' rights generally and except to the extent that injunctive
or other equitable relief is within the discretion of a court, (ii) none of
MTVN, Imagine, VLLC, or, to the knowledge of Imagine and VLLC, any other party
to any such Contract is in breach thereof or default thereunder, and (iii) there

Imagine and VLLC, any event that, with the giving of notice or the lapse of time
or both, would constitute such a breach or default, except with respect to the
foregoing clauses (i)-(iii) for all such failures to be valid, binding and
enforceable and such breaches, defaults, events and disputes which would not,
individually or in the aggregate, reasonably be expected to have a material
adverse effect on the Imagine Assets and the VLLC Assets, taken as a whole;
provided, however, that any qualification in this Section 4.5 as to knowledge
shall not apply to the extent any other party to a Contract is MTVN or a
Controlled Affiliate of MTVN.

                  4.6. No Changes. Except as set forth on Schedule 4.6, since

<PAGE>   30
                                                                              24

Business of the Partnership and which would not interfere with or frustrate the
transactions contemplated by this Agreement and otherwise only in the ordinary
course of business consistent with past practices, and since December 31, 1998,
there has not been: (i) any material adverse change in the businesses
constituting the MTVN Contribution, except for material adverse changes that may
have resulted from the public announcement of the execution of the MOU, or (ii)
any termination of any Contract to which any of Imagine, MTVN (insofar as it
relates to the MTVN Contribution) or VLLC is a party (other than Imagine
Excluded Contracts and Contracts which expire in accordance with their terms and
Contracts to which MTVN and its Controlled Affiliates are the only parties,
except for any such termination which would not, individually or in the
aggregate, reasonably be expected to have a material adverse effect on the
Imagine Assets and the VLLC Assets, taken as a whole.

                  4.7. No Brokerage. There is no investment banker, broker,
finder or other similar intermediary which has been retained by any MTVN Entity
or is authorized to act on behalf of any MTVN Entity or any Affiliates thereof
or any of their officers and directors who might be entitled to any fee or
commission from Liberty, any of the Tune Entities or any Affiliates thereof, the
Partnership or any of its subsidiaries upon consummation of the transactions
contemplated by this Agreement or the Operative Agreements.

                  4.8. Absence of Litigation. Except as set forth on Schedule

pending or, to the knowledge of any MTVN Entity, threatened against any MTVN
Entity or their business and operations insofar as it relates to the Imagine
Assets or the VLLC Assets, at law or in equity, before or by any arbitrator or
Governmental Entity, except for any such actions, suits, investigations, claims,
arbitrations or litigations which would not, individually or in the aggregate,
reasonably be expected to have a material adverse effect on the Imagine Assets
and the VLLC Assets, taken as a whole. No MTVN Entity is currently operating
under or subject to any order, award, judgment, writ, decree, determination or
injunction, in any such case specific to the use by any MTVN Entity of the
Imagine Assets or the VLLC Assets, of any arbitrator or Governmental Entity.

                  4.9.     No Real Property; Totality and Condition of Assets.

                  (a) Neither Imagine (solely with respect to the Imagine
Assets) nor VLLC, after giving effect to the contribution to VLLC of the VLLC
Assets, owns, leases or has any interest in any real property which are
exclusive to its businesses.

                  (b) Each of Imagine and VLLC, after giving effect to the
contribution to VLLC of the VLLC Assets, is the sole owner of and has good title
to or a valid leasehold interest in the Imagine Assets and the VLLC Assets,
respectively, free and clear of any Liens, except for and subject only to Liens
listed in Schedule 4.9(b) and those which would not, individually or in the
aggregate be expected to have a material adverse effect on the Imagine Assets
and the VLCC Assets, taken as a whole. The Imagine Assets and the VLLC Assets
are in all material respects in good operating condition and repair in
accordance with normal and customary industry practices for items of comparable
age and use, reasonable wear and tear excepted.

                  4.10.    Compliance with Laws; Permits.

                  (a) Each of the MTVN Entities is in compliance, in all
material respects, with all Laws applicable to its use and operation of the
Imagine Assets, the VLLC Asset and the Domain Names.

                  (b) Each of the MTVN Entities has obtained and holds all
Permits (collectively, the "MTVN Permits") necessary in order to use and operate
the Imagine Assets, the VLLC Assets as currently used and operated, none of
which has been modified or rescinded and all of which were validly issued and
are in full force and effect. No event has occurred and is continuing that
permits, or after notice or lapse of time or both would permit, any modification
or termination of any MTVN Permit. Each of the MTVN Entities has all rights

obligations relating to the MTVN Contribution or the Domain Names other than (i)
the VLLC Liabilities and the Imagine Liabilities being assumed by the
Partnership pursuant to the VLLC and Imagine Contribution Agreements (which,
with respect to periods prior to the Closing, are limited to certain accounts

arising after, and with respect to the period following, the Closing under the

consummation of the transactions contemplated by this Agreement, will (A)
increase the amount of any payments or benefits otherwise payable under any
Assigned MTVN Employment Contract, (B) result in the acceleration of the time of
payment, exercisability, funding or vesting of any such payments or benefits, or

under any Assigned MTVN Employment Contract; and

                          (iv) No payment or series of payments that would

right, title or interest of VLLC under the Trademark License Agreement, the
Partnership Agreement, the Technology Sharing and License Agreement and the

contribute the same as contemplated under this Agreement without any conflict
with or infringement of the rights of others, and such rights will not be

come into conflict with any Intellectual Property of third parties, and are not
presently so interfering, infringing, misappropriating or in conflict therewith,

or violated any of the Intellectual Property of any other Person, and (without

                            SURVIVAL; INDEMNIFICATION

                  7.1. Survival. All representations, warranties, covenants and
agreements contained in this Agreement or in any schedule, exhibit, certificate,
agreement, document or statement delivered pursuant hereto shall survive
indefinitely after (and not be affected in any respect by) the Closing and any
investigation conducted by any party hereto; provided, however, that the

related thereto and in any certificate delivered in connection herewith with
respect to any of those representations and warranties will terminate and expire
on the second anniversary of the Closing Date except as follows: (a) the
representations and warranties which relate expressly or by necessary
implication to Taxes, ERISA or other employment or labor matters (as modified by
the schedules related thereto) will survive until the expiration of the
applicable statutes of limitations (including all periods of extension and
tolling); (b) the representations and warranties which relate expressly or by
necessary implication to the environment or environmental Laws (as modified by
the schedules related thereto) will survive for a period of five years from the

indefinitely. After a representation and warranty has terminated and expired, no
indemnification will or may be sought pursuant to this Article 7 on the basis of
a breach or inaccuracy of that representation and warranty by any Person who
would have been entitled pursuant to this Article 7 to indemnification on the
basis of a breach or inaccuracy of that representation and warranty prior to its
termination and expiration; provided that in the case of each representation and
warranty that will terminate and expire as provided in this Section 7.1, no
claim presented in writing for indemnification pursuant to this Article 7 on the
basis of a breach or inaccuracy of that representation and warranty prior to its
termination and expiration will be affected in any way by that termination and
expiration.

warranty of any of the MTVN Entities and the Losses arising from such inaccuracy
or breach for purposes of this indemnity, such representation and warranty shall
be read as if it were not qualified by materiality, including, without
limitation, qualifications indicating accuracy in all material respects, or
accuracy except to the extent the inaccuracy will not have a material adverse
effect); provided, the MTVN Entities shall not be required to indemnify the Tune
Indemnified Parties or the Partnership Indemnified Parties under this Section
7.2(a) for any Losses arising out of a breach of any of the representations or
warranties contained herein insofar as they relate to (x) the failure to
disclose the need for any consents required in connection with nonassignment or
change of control provisions in connection with the transactions contemplated
hereby or (y) any termination or breach or other effect of the failure to obtain
a waiver or consent in connection with the transactions contemplated hereby; and
provided further that the indemnification under this clause (a), insofar as it

Partnership pursuant to the applicable Contribution Agreements, shall be for the
benefit only of the Partnership Indemnified Parties and not the Tune Indemnified
Parties.

perform, satisfy and discharge any of their respective covenants, agreements,
undertakings, liabilities or obligations under this Agreement and the

however, that the indemnification under this clause (c) shall be for the benefit
only of the Partnership Indemnified Parties and not the Tune Indemnified

representation or warranty of any of TCI Music, SonicNet or Box and the Losses
arising from such inaccuracy or breach for purposes of this indemnity, such
representation and warranty shall be read as if it were not qualified by
materiality, including, without limitation, qualifications indicating accuracy
in all material respects, or accuracy except to the extent the inaccuracy will
not have a material adverse effect); provided, TCI Music, SonicNet and Box shall
not be required to indemnify the MTVN Indemnified Parties or the Partnership
Indemnified Parties under this Section 7.3(a) for any Losses arising out of a
breach of any of the representations or warranties set forth herein insofar as

effect of the failure to obtain a waiver or consent in connection with the
transactions contemplated hereby; and provided further that the indemnification
under this clause (a), insofar as it relates to any assets or businesses
contributed or to be contributed to the Partnership or to any liabilities or
obligations assumed or to be assumed by the Partnership pursuant to the

were incurred since the date thereof in the ordinary course of business and
consistent with past practice and are not in excess of historical amounts for
comparable periods (but not including liabilities or obligations relating to any
Tune Benefit Plan) and (y) for periods from and after the Closing arising under
the Tune Assigned Contracts; provided, however, that the indemnification under
this clause (c) shall be for the benefit only of the Partnership Indemnified
Parties and not the MTVN Indemnified Parties; and provided further that nothing
contained in the foregoing shall limit the liabilities and obligations of the
Partnership pursuant to Sections 3.4, 3.5 and 3.6 of this Agreement.

                  (d) any Taxes imposed on any of the Tune Entities attributable

hold the MTVN Indemnified Parties and the Partnership Indemnified Parties,
without duplication, harmless from and against, and agree promptly to defend any
such Indemnified Party from and reimburse any such Indemnified Party for, any
and all Losses which any such Indemnified Party may suffer or incur, or become

Agreement or in any instrument or certificate delivered by it in accordance
herewith (it being understood and agreed that, notwithstanding anything to the
contrary contained in this Agreement, to determine if there had been an

                  (b) any failure by Liberty to carry out, perform, satisfy and
discharge any of its covenants, agreements, undertakings, liabilities or
obligations under this Agreement or the Parent Agreement.

                  7.5. Indemnification by the Partnership. The Partnership shall
indemnify and hold the MTVN Indemnified Parties and the Tune Indemnified Parties
harmless from and against, and agree promptly to defend any such Indemnified
Party from and reimburse any such Indemnified Party for, any and all Losses
which any such Indemnified Party may suffer or incur, or become subject to
(including, with respect to TCI Music, any Losses suffered or incurred by any
affiliated entity under the Irrevocable Standby Letter of Credit dated January
13, 1999 in the amount of $459,000 issued by Bank of America NT & SA for the
benefit of TM Park Avenue Associates), arising out of or resulting from, without
duplication, (a) any failure by the Partnership to carry out, perform, satisfy
and discharge any of its covenants, agreements, undertakings, liabilities or
obligations under this Agreement and the Contribution Agreements to which it is
a party, (b) the VLLC Liabilities and the Imagine Liabilities, (c) the Box LLC
Liabilities and the SonicNet LLC Liabilities, (d) any liabilities which arise
out of a breach or violation of any non-assignment or change of control
provision insofar as such breach or violation resulted from or arose out of
(including as a result of a claim of anticipatory breach of contract) the
consummation of the transactions contemplated hereby, including any failure to
obtain any consent or waiver, and (e) all other liabilities assumed by the
Partnership (but only to the extent so assumed) under any Contribution
Agreements or under any other Contract entered into by or assigned or
contributed to, or to be assigned or contributed to, the Partnership in
connection herewith; provided, however, that the Partnership shall not be
obligated to indemnify
<PAGE>   52
                                       46


any indemnified party with respect to any obligations that relate to pre-Closing
periods (other than those relating to certain accounts payable, accrued
expenses, prepayments and similar working capital items identified on the
balance sheets attached to Schedule 4.12 or 6.17 hereto or of the same types as
such items reflected on the balance sheet which were incurred since the date
thereof in the ordinary course of business and consistent with past practice and
are not in excess of historical amounts for comparable periods) or arise out of
a breach or violation prior to the Closing of any provision (other than a
non-assignment or change in control provision insofar as it relates to the
consummation of the transactions contemplated hereby, for which the Partnership
shall provide indemnity under clause (d) above) of any Contract assigned or
contributed to the Partnership in connection herewith.

                  7.6. Tipping Amount; Limitation on Indemnification.
Notwithstanding any other provision in this Agreement to the contrary, the MTVN
Entities shall not be obligated to pay any claims for indemnification under
Section 7.2(a), TCI Music, SonicNet and Box shall not be obligated to pay any
claims for indemnification under Section 7.3(a) and Liberty shall not be
obligated to pay any claims for indemnification under Section 7.4(a) (other
than, in each case, any such claim based on a No Basket Representation), unless,
in each case, the total Losses giving rise to such claims under Section 7.2(a),
7.3(a) or 7.4(a), as applicable, exceed $3,000,000 (the "Tipping Amount");
provided that if, in any such case, the aggregate amount of such Losses exceeds
the Tipping Amount, then the applicable indemnifying party shall be obligated to
pay the full amount of such Losses, including the Tipping Amount, except for a
deductible amount of $1,500,000. Notwithstanding anything to the contrary in
this Agreement, no group of indemnifying parties' cumulative indemnity
obligations under any of Sections 7.2(a), 7.3(a) or 7.4(a), excluding
indemnification claims for Losses arising out of any inaccuracy or breach of the
No Basket Representations, shall exceed $150,000,000, it being understood that
an obligation for indemnity under Section 7.2(a), 7.3(a) or 7.4(a), on the one
hand, and any other paragraph of Section 7.2, 7.3 or 7.4, on the other hand,
shall be deemed to be an obligation under Section 7.2(a), 7.3(a) or 7.4(a) for
purposes of the foregoing $150,000,000 limitation, but not for purposes of the
Tipping Amount.

                  7.7. Exclusive Remedy. The rights and remedies of the parties
hereto under this Article 7 are exclusive and in lieu of any and all other
rights and remedies which the parties hereto may have against the other under
this Agreement or any Contribution Agreement, with respect to (x) the breach or
inaccuracy of any representation or warranty made (or deemed made) by a party
hereto in or pursuant to this Agreement or any Contribution Agreement or (y) any
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
delivered by it in accordance herewith or therewith; provided, however, that
this sentence shall not limit the rights of the parties hereto to seek specific
performance of any provision of this Agreement or any Contribution Agreement.

                  7.8. Indemnification Procedures. Any Party asserting a right
to indemnification under Section 7.2, 7.3, 7.4 or 7.5 shall so notify in writing
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
<PAGE>   53
                                                                              47


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.

                  8.2. Governing Law. This Agreement and the rights and
obligations of the parties hereto, and any claims or disputes relating thereto,
shall be governed by and construed under and in accordance with the laws of the
State of New York, excluding the choice of law rules thereof.

                  8.3. Severability. If any provision of this Agreement shall be
held to be illegal, invalid or unenforceable, that provision will be enforced to
the maximum extent permissible so as to effect the intent of the parties and the
validity, legality and enforceability of the remaining provisions shall not in
any way be affected or impaired thereby. If necessary to effect the intent of
the parties, the parties will negotiate in good faith to amend this Agreement to
replace the unenforceable language with enforceable language which as closely as
possible reflects such intent.

                  8.4. Amendments. This Agreement may be modified or amended
only by a written amendment signed by each party hereto.

                  8.5. Counterparts. This Agreement may be executed in one or
more counterparts (and all signatures need not be on any one such counterpart),
with all such counterparts together constituting one and the same instrument.

                  8.6. Entire Agreement. This Agreement contains the entire
agreement of the parties with respect to the subject matter hereof and
supersedes any and all prior agreement and understandings, whether written or
oral, with respect to the subject matter hereof, including the MOU.

                  8.7. No Presumption. This Agreement shall be construed without
regard to any presumption or rule requiring construction or interpretation
against the party drafting or causing any instrument to be drafted.

                  8.8. Binding on Viacom. The parties acknowledge that MTVN is a
division of Viacom and that, consequently, Viacom is obligated to perform the
obligations to be paid or performed by MTVN hereunder. Insofar as this Agreement
refers to MTVN in the context of an operating business, it shall refer only to
the operating unit or units of Viacom that on a day-to-day basis operate the
business of MTV: Music Television or VH1 Music First. In addition, 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, relate
to Viacom.

                  8.9. Parties in Interest; Limitation on Rights of Others. Any
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
<PAGE>   55
                                       49


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
Agreement may be waived (either generally or in a particular instance and either
retroactively or prospectively) by the party or parties entitled to enforce such
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

for itself and its property, to the exclusive jurisdiction of any New York State
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
appellate court from any such court, in any suit, action or proceeding arising
out of or relating to this Agreement or any Contribution Agreement, or for
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
proceeding may elect in its sole discretion. Each party also hereby irrevocably
and unconditionally agrees that a final judgment in any such suit, action or
proceeding shall be conclusive and may be enforced in other jurisdictions by
suit on the judgment or in any other manner provided by law.

                  (b) Each party hereby irrevocably and unconditionally waives,
to the fullest extent it may legally and effectively do so, any objection which
it may now or hereafter have to the laying of venue of any suit, action or
proceeding arising out of or relating to this Agreement or any Contribution
Agreement 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, and any appellate
court from any such court. Each party hereby irrevocably waives, to the fullest
extent permitted by law, the defense of an inconvenient forum to the maintenance

right to object, with respect to such suit, action or proceeding, that such
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 service of process in the manner provided for the giving of notices pursuant
to this Agreement or any Contribution Agreement. Nothing in this Agreement or
any Contribution Agreement shall affect the right of either party to serve
process in any other manner permitted by law.
