the MTV Programming (as defined below) for use in connection with the Business
(as defined below) upon the terms and conditions set forth herein;

         WHEREAS, simultaneously herewith MTVN and VLLC are entering into a
Trademark License Agreement (the "Trademark License Agreement") pursuant to
which, among other things, MTVN is granting a license to VLLC to use certain
trademarks owned by MTVN for use in connection with the Business; and

         WHEREAS, the parties agree in principle that the Licensed Services (as
defined below) shall be the primary vehicle for showcasing the MTV Programming

music-themed online service in a manner which would be injurious to the Licensed
Services; and

         WHEREAS, immediately after the execution of this Agreement VLLC shall
assign to the Partnership (as defined below) all of VLLC's rights and

         would require MTVN or any of its Affiliates other than VLLC to make any
         payment on a direct or incremental basis to any Person as a result of
         such use thereof.

                           (ii) VLLC acknowledges that it is familiar with the
         high standards, quality, style and image of programming produced by
         MTVN and its Controlled Affiliates and agrees to use the MTV
         Programming in a manner that is consistent with such high standards,
         quality, style and image and in accordance with the terms of this
         Agreement.

                           (iii) VLLC shall be responsible for securing all
         necessary performing rights licenses or other authorizations, including
         all costs therefor, necessary for the lawful transmission of the MTV
         Programming being licensed to VLLC hereunder. To the extent that any
         licenses or other authorizations are required of any Person in order
         for VLLC to satisfy its obligation under this provision, VLLC shall
         notify MTVN of the need for such rights and MTVN may, at its sole and
         exclusive discretion to be exercised in good faith, secure such rights
         in its own name at VLLC's expense.

                           (iv) VLLC may include programming other than MTV
         Programming or Additional MTV Programming ("Non-MTV Programming") as
         part of the Business operated by it, provided that it does so in a
         manner that does not result in a likelihood of confusion regarding the
         source of the Non-MTV Programming and the MTV Programming or Additional
         MTV Programming.

                           (v) MTVN may from time to time notify VLLC of any
         country or jurisdiction within the Territory in which MTV Programming
         or Additional MTV Programming is not to be used in connection with the
         Licensed Services because MTVN has determined that such use may
         infringe upon the rights of any Person or is otherwise determined by
         MTVN in the exercise of its reasonable judgment to be contrary to any
         laws, in violation of a court order or likely to cause material
         impairment of MTVN's relations with talent, industry or any government.
         Upon receipt of such notice VLLC will terminate its use of the MTV
         Programming in connection with the Licensed Services in such country or
         jurisdiction, in that, if technically feasible and commercially
         reasonable, VLLC will block transmission to such country or
         jurisdiction, and otherwise will not target any MTV Programming to such
         country or jurisdiction (such as by use of advertising or marketing
         materials, local language or programming selections tailored to such
         country or jurisdiction). Prior to first using any MTV Programming in
         connection with the Licensed Services in any country or jurisdiction
         within the Territory, VLLC shall give notice to MTVN of its intent to
         do so, and VLLC shall not do so if, following such notice to MTVN, VLLC
         receives notice from MTVN that such use may infringe upon the rights of
         any Person or is otherwise determined by MTVN in the exercise of
         reasonable judgment to be likely to cause material impairment of MTVN's
         relations with talent, industry or any government. Without limiting the
         foregoing, pursuant to MTVN's agreements related to the Tricast/Asia
         joint venture referenced in Schedule A, and for as long as such
         agreements are binding on MTVN, VLLC shall have no right to own or
         operate any Licensed Service which is targeted to 15 - 24 year old
         audiences in Asia (as defined in accordance with the definition of the
         Asia "territory" set forth in paragraph 1 of Schedule 1 to the Parent
         Agreement) and branded with any of the following trademarks or service
         marks: MTV, MTV: MUSIC TELEVISION, MTV: MUSIC TELEVISION & Design, MTV
         ONLINE, MTV ONLINE & Design, or MTV.COM.

                           (vi) VLLC shall not have the right to display, or
         transmit or deliver for display by an end user, any MTV Programming
         intended for a single exhibition or viewing of more than ten (10)
         minutes in length regardless of whether, in the case of transmission or
         delivery in downloadable format, downloadable in a single file or in
         multiple files.

                  (d) Acceptance and Rejection of MTV Programming. MTVN shall,
on an ongoing basis, apprise VLLC as to, and shall be reasonably available to
discuss, the availability of MTV Programming for use by VLLC in accordance with
Section 2(a). In furtherance of the purposes of the parties recited herein, VLLC
will notify MTVN from time to time of any MTV Programming which VLLC selects for
delivery to it for use hereunder and MTVN shall thereafter deliver to VLLC, in
accordance with the provisions of Section 2(l) hereof, the requested MTV
Programming, provided that MTVN will not be required to deliver any programming
or program elements which at the time of MTVN's receipt of such request no
longer meets the definition of MTV Programming as set forth in Section 1 hereof.

                  (e) Contribution to Capital. The license under this Agreement
shall be a royalty-free contribution to capital from MTVN to VLLC.

                  (f) Potential Infringement. VLLC shall use its reasonable best
efforts to monitor and to promptly call to MTVN's attention the existence of any
materials which could reasonably be considered to be an infringement of any
element of the MTV Programming (a "Potential Infringement"). In the event of any
Potential Infringement, MTVN shall have the sole right, after consultation with
VLLC in the event such Potential Infringement concerns subject matter within the
Business, to determine whether a proceeding should be brought against any third
parties. In the event that MTVN decides to take action against such third
parties, VLLC agrees to use its reasonable best efforts to cooperate fully with
MTVN to prosecute such action and to furnish any documentary evidence or
evidentiary materials that MTVN may reasonably require, but that MTVN shall have
sole control over such action, including any settlement thereof. In addition,
VLLC undertakes to use its reasonable best efforts to assist and cooperate with
MTVN in the prosecution of any lawsuits, legal actions or other proceedings
which, in the opinion of MTVN, are necessary or advisable to protect the rights
in the MTV Programming; provided, however, that VLLC shall not be required to
incur or pay any costs or expenses (other than de minimis amounts) occasioned by
such cooperation, and shall be reimbursed by MTVN for such expenditures VLLC
does make, including, at MTVN's request, participating in such proceedings as a
party. All damages, profits, penalties, and other consideration or compensation
which may be recovered in connection with such action shall be solely for the
account of MTVN.

                  (g) Maintenance of Intellectual Property Rights in MTV
Programming.

                           (i) MTVN shall have the sole right to protect (via
         registration, renewal, recordation or otherwise, as applicable) the
         intellectual property rights in the MTV Programming throughout the
         world. Under no circumstances shall VLLC take any action or permit any
         action to be taken to register, renew, record or otherwise protect the
         MTV Programming without the prior written consent of MTVN.

                           (ii) VLLC shall assist and cooperate with MTVN, at
         MTVN's request and expense, in registering, renewing, recording or
         otherwise protecting the MTV Programming, and shall execute and deliver
         any documents, affidavits, user information and other materials
         requested by MTVN to be executed and delivered, by VLLC in connection
         therewith including, without limitation, if MTVN considers it
         advisable, the recording of VLLC as a licensee or registered user of
         any or all of the MTV Programming in any jurisdiction with any
         Governmental Entity or other authority. VLLC shall execute and deliver
         any documents submitted to VLLC by MTVN for this purpose. Likewise, if
         any such recording is to be terminated or canceled, VLLC shall execute
         any documents, affidavits, and related materials submitted to it by
         MTVN for this purpose. Without limitation of the foregoing, both during
         the Term and after the expiration or termination of this Agreement,
         VLLC shall, upon MTVN's request, acknowledge in writing MTVN's (or its
         wholly owned subsidiaries') prior exclusive right, title and interest
         in and to the MTV Programming.

                           (iii) VLLC shall not, under any circumstances, either
         during the Term or after the expiration or termination of this
         Agreement, attempt to register, renew, record or otherwise protect or
         use any copyright, trademark, service mark or trade name which is the
         same as, which contains or which is substantially similar to any MTV
         Programming or any element thereof which is protectable by intellectual
         property laws in any way. After the termination of this Agreement, VLLC
         shall not falsely hold forth, declare, or in any way suggest that it
         has any connection whatsoever with MTVN or any television programming
         services produced by MTVN or its Controlled Affiliates, or any element
         of the MTV Programming. VLLC further agrees that it will not take any
         action that it knows or should know will, or is reasonably likely to,
         subject any MTV Programming to ridicule or disrepute. Notwithstanding
         the foregoing, VLLC agrees that it will not take any such action that
         it knows or should know will, or is reasonably likely to subject Viacom
         International, Inc., or any of its Affiliates, to ridicule or disrepute
         unless otherwise agreed by MTVN.

                           (iv) VLLC shall further comply, at VLLC's expense,
         with all requirements of the Berne Convention, the Universal Copyright
         Convention and any other copyright or similar rights protection laws,
         treaties or provisions, as MTVN deems necessary to obtain or maintain
         protection of the MTV Programming. To the extent that any filings are
         necessary in order for VLLC to satisfy its obligation under this
         provision, VLLC shall notify MTVN of the need for such filings and MTVN
         may, at its sole and exclusive discretion to be exercised in good
         faith, make such filings in its own name at VLLC's expense.

                  (h) Right of Approval of Materials. VLLC agrees not to use,
procure or permit the use of any MTV Programming until such use has been
approved by MTVN which approval shall not be unreasonably withheld or delayed.
Once the use of MTV Programming has been approved by MTVN, VLLC thereafter may
continue to use such MTV Programming, strictly in accordance with the terms of
the approval granted and without altering in any way such MTV Programming or the
manner in which it is used under this Agreement. Notwithstanding the foregoing,
however, MTVN has the continuing right to reexamine any use of any item of the
<PAGE>   8
                                                                               8

MTV Programming by VLLC, and may at any time require VLLC to cease using any
such item or otherwise modify such use if reasonably necessary in MTVN's
judgment to avoid infringement, violation of law or court order or material
impairment of MTVN's relations with talent, industry or any government.

                  (i) VLLC's Reporting. From time to time during the Term, VLLC
shall report to MTVN all information that MTVN may reasonably require regarding
VLLC's use of the MTV Programming.

                  (j) Additional Terms. VLLC agrees to use the MTV Programming
strictly in accordance with this Agreement, and such standards, specifications
and instructions concerning the manner of presentation or use of MTV Programming
as are issued by MTVN (in writing) to VLLC from time to time (such standards,
specifications and instructions being referred to collectively as the
"Additional Terms"). Each reference herein to this Agreement shall be deemed to
be a reference to the terms of this Agreement as supplemented or modified (i) by
the Additional Terms, as in effect from time to time, and (ii) with respect to
any particular use of any MTV Programming, by the terms of the approval of such
use granted by MTVN pursuant to this Agreement.

                  (k) Additional MTV Programming. MTVN shall, on an ongoing
basis, apprise VLLC as to, and shall be reasonably available to discuss, the
availability of Additional MTV Programming for use by VLLC. VLLC will notify
MTVN from time to time of any Additional MTV Programming which VLLC would like
to select for delivery to it for use hereunder and MTVN shall thereafter deliver
to VLLC, in accordance with the provisions of Section 2(l) hereof, the requested
Additional MTV Programming, provided that MTVN will not be required to deliver
any programming or program elements which at the time of MTVN's receipt of such
request no longer meets the definition of Additional MTV Programming as set
forth in Section 1 hereof. Notwithstanding the foregoing, (i) MTVN shall not be
required to deliver to VLLC any Additional MTV Programming unless MTVN has
received VLLC's commitment to pay any amounts actually required to be paid to
any Person to obtain the rights necessary to exhibit such Additional MTV
Programming in the manner VLLC intends to exhibit it or to any entity designated
by MTVN promptly after receipt of an invoice therefor, as the case may be; and
(ii) MTVN shall provide reasonable cooperation, but shall have no obligation to
obtain the rights or negotiate with or obtain agreements from any Person to
accept such amounts for the purpose of making Additional MTV Programming
available for VLLC; provided further, that in the event VLLC desires to
negotiate for or obtain any such rights or agreements from a third party, VLLC
and MTVN will consult with one another, and VLLC agrees not to approach any
third party for the purpose of negotiating or obtaining such rights without
first obtaining MTVN's prior written consent, which consent will not be withheld
by MTVN unless it has a good faith business reason for withholding such consent.
To the extent and for the period that MTVN obtains the rights to such
programming and licenses it to VLLC, such Additional MTV Programming shall be
deemed to be MTV Programming for purposes of this Agreement.

                  (l) Delivery of MTV Programming.

                           (i) MTVN shall use its reasonable efforts to make
         available on a timely basis to VLLC any MTV Programming licensed
         hereunder, subject to restrictions or constraints imposed by any
         Governmental Entity. MTVN shall deliver any MTV Programming to VLLC in
         sufficient time for use in accordance with the proposed schedules of
         VLLC, provided that MTVN receives a copy of such proposed use schedules
         within a reasonable number of days prior to the proposed use of such
         MTV Programming. Any materials containing MTV Programming supplied to
         VLLC shall be and shall remain at all times the exclusive property of
         MTVN and, while in VLLC's possession or responsibility, any loss or
         damage shall be at the sole risk of VLLC. VLLC shall take reasonable
         precautions to safeguard all materials in its possession that are
         specified in this subparagraph and shall use its reasonable efforts to
         prevent any theft, unauthorized use, copying or duplication by others
         of any materials furnished by MTVN or duplicated by VLLC.

                           (ii) MTVN shall use its reasonable efforts to deliver
         MTV Programming in the format requested by VLLC. Upon the request of
         MTVN, VLLC shall reimburse MTVN for the costs of alterations to the
         format of MTV Programming which are requested by VLLC.

                           (iii) VLLC agrees to return all original materials
         supplied under this Agreement within a reasonable time period after
         their receipt from MTVN, provided that, subject to the immediately
         succeeding sentence, VLLC may duplicate and return copies of such
         original materials. At MTVN's direction, VLLC shall either (A) return
         to MTVN any or all materials supplied under this Agreement within a
         reasonable time period after their permitted use, including any copies
         or duplicates of any or all such materials (collectively, "MTV
         Materials") or (B) within ten (10) days after their permitted use (x)
         erase or destroy, as the case may be, such MTV Materials and (y)
         deliver to MTVN a certificate of erasure or destruction, as the case
         may be, which certificate shall be in a form satisfactory to MTVN.

                           (iv) All costs including, without limitation, dubbing
         costs and transportation costs (including, without limitation, all
         taxes, duties, customs charges, second use fees, insurance and
         forwarding charges) directly attributable to the delivery of the MTV
         Programming by MTVN to VLLC and the return by VLLC to MTVN of any MTV
         Materials (including the cost of erasure and certifying same, where
         required by MTVN) shall be borne by VLLC. All costs relating to the
         conversion of the tapes, disks and other forms of transmission from one
         format to another format in connection with the use thereof by VLLC
         shall be borne by VLLC. All risk of loss or damages to any MTV
         Materials when such MTV Materials are in transit or the custody of VLLC
         shall be borne solely by VLLC.

                  (m) Reservation of Rights.

                           (i) MTVN reserves all rights not expressly granted to
         VLLC in this Agreement. Without limitation of the foregoing, VLLC shall
         have no right to use any MTV Programming, except in such manner and at
         such times as are expressly provided in this Agreement. Without
         limitation of the foregoing, VLLC shall have no right to use any
         trademarks, tradenames or other intellectual property rights of MTVN or
         its licensors embodied in the MTV Programming except as part of the MTV
         Programming and as expressly licensed pursuant to Section 2(a) hereof
         or in the Trademark License Agreement.

                           (ii) Without limitation of clause (i) above, MTVN
         retains all merchandising rights with respect to the MTV Programming.
         VLLC acknowledges and agrees that it shall have no right to develop,
         manufacture or sell any merchandise of any nature whatsoever
         incorporating the MTV Programming, except upon receipt of the prior
         written authorization from MTVN.

                           (iii) The licenses granted herein are nontransferable
         and do not include any right to sublicense or grant further licenses
         with respect to any MTV Programming, provided, however, that VLLC shall
         have the right to exercise the licenses granted hereunder through its
         wholly-owned subsidiaries.

                  (n) VLLC Programming. In the event that VLLC creates
programming or obtains any rights from any Person for the use of any programming
that would allow VLLC to license or sublicense such rights ("VLLC Programming"),
MTVN shall have both the Right of First Negotiation and the Right of First
Refusal with respect to the licensing or sublicensing by VLLC of the VLLC
Programming. For purposes of this Section 2(n), "Right of First Negotiation"
shall mean, with respect to an opportunity of VLLC to license or sublicense
rights in VLLC Programming (the "Opportunity"), the right of MTVN to be the
first Person that VLLC offers the Opportunity to and/or negotiates with
regarding the Opportunity, and includes the obligation of VLLC to negotiate in
good faith for a reasonable period of time with MTVN regarding the Opportunity.
If the parties cannot negotiate terms and conditions in good faith mutually
acceptable to them within thirty (30) days, VLLC shall be free to negotiate with
any other non-affiliated Person with respect to the Opportunity, subject to
MTVN's Right of First Refusal. For purposes of this Section 2(n), "Right of
First Refusal" shall mean, with respect to an Opportunity, the right of MTVN to
be notified of all of the material terms of any bona fide proposed transaction
with any Person (who shall be identified in the notice) regarding the
Opportunity to have the exclusive option for a period of thirty (30) days to
contract with VLLC on the same terms as those described in the notice with
respect to the Opportunity. If MTVN does not exercise such option within such
thirty (30) day period, or sooner expressly rejects such option, VLLC shall
thereupon be free to contract with any non-affiliated Person with respect to the
Opportunity, on terms no less favorable to VLLC than those set forth in the
notice, for a period of ninety (90) days. If VLLC does not so contract with any
non-affiliated Person within such ninety (90) day period, the notice and option
provisions and the foregoing procedures hereof shall again apply with respect to
such Opportunity.

                   SECTION 3. COPYRIGHT AND TRADEMARK NOTICES

                  To the extent that MTV Programming provided to VLLC contains a
copyright/trademark notice, VLLC shall use such MTV Programming without deletion
or alteration of the copyright/trademark notice. No other copyright/trademark
notice whatsoever may be included by VLLC on the MTV Programming unless MTVN has
given VLLC prior written consent thereto, except that in the event that any MTV
Programming provided to VLLC does not contain a copyright/trademark notice, VLLC
shall insure that, one or the other of the following copyright/trademark notices
or a shorter notice as approved by MTVN from time to time appears in the MTV
Programming prior to its use by VLLC:

                  "(C)Copyright {Insert Year} MTV Networks. All Rights Reserved.
                  MTV and MTV logos are trademarks of MTV Networks, a division
                  of Viacom International Inc."

                  (C)Copyright {Insert Year} MTV Networks. All Rights Reserved.
                  VH1 Music First and VH1 logos are trademarks of MTV Networks,
                  a division of Viacom International Inc.

MTVN may, at any time and from time to time, require the addition of a similarly
customary copyright or trademark notice or change the copyright/trademark notice
referred to above and VLLC agrees to act in accordance with such requirements.

                        SECTION 4. CERTAIN VLLC COVENANTS

                  (a) Cooperation with MTVN Representatives. VLLC agrees to
provide reasonable access to its facilities to MTVN representatives, to
cooperate fully with the reasonable requests of such representatives and to work
expeditiously and cooperatively with such representatives to resolve promptly
any reasonable concerns of MTVN whatsoever regarding VLLC's fulfillment of its
obligations under this Agreement in order to ensure the protection of all of the
MTV Programming.

                  (b) Storing and Indexing of all Physical Materials. VLLC
agrees to provide space to store and index all physical materials including, but
not limited to, disks and tapes containing the MTV Programming, and to provide
in connection therewith security facilities and personnel, including a vault or
other security procedures, and including log-in, log-out requirements which, in
each case, are as favorable as those which are provided to any other physical
materials in the possession of VLLC.

                  (c) Agreements Regarding Intellectual Property Rights in MTV
Programming. VLLC shall not, under any circumstances, either during the Term or
after the expiration or termination of this Agreement, make any claim, institute
any proceeding or launch any attack or suit, in any jurisdiction, with respect
to MTVN's use, ownership, right, title or interest in any MTV Programming or any
intellectual property rights as they are embodied therein, existing during the
Term of this Agreement.

                       SECTION 5. CONFIDENTIAL INFORMATION

                  Each of VLLC and its wholly-owned subsidiaries shall, and
shall use its reasonable best efforts to cause its and their respective
officers, directors, employees, attorneys, accountants, and agents
(collectively, "Agents") to, keep secret and retain in strictest confidence any
and all Confidential Information, and shall not disclose such Confidential
Information, and shall use its reasonable best efforts to cause its Agents not
to disclose such Confidential Information, to any Person other than VLLC, its
wholly-owned subsidiaries, or their respective Agents, except (i) for such
disclosures as may be required by law or legal process, disclosures to VLLC's
counsel, or disclosures pursuant to any listing agreement with, or the rules or
regulations of, any securities exchange on which securities of VLLC or any such
wholly-owned subsidiaries are listed or traded (in which event VLLC shall so
notify MTVN as promptly as practicable (and, if possible, prior to making such
disclosure) and shall seek confidential treatment of such information) (ii) as
may be necessary to establish or enforce its rights hereunder; and (iii) with
the prior written consent of MTVN. For purposes of this Section 5,

                  "CONFIDENTIAL INFORMATION" shall mean (1) the terms of this
Agreement and (2) all business and technical information relating to MTVN's
businesses that is proprietary to MTVN or otherwise not available to the general
public; provided, however, that such Confidential Information shall not include
any information that (a) is or has become generally available to the public
other than as a result of a disclosure by VLLC, its Controlled Affiliates or its
Agents, (b) has been independently developed by VLLC or a Controlled Affiliate
of VLLC or (c) is, or becomes available to VLLC or a Controlled Affiliate of
VLLC on a non-confidential basis from a third party having no obligation of
confidentiality to a party hereto and which has not itself received such
information directly or indirectly in breach of any obligation of
confidentiality.

             SECTION 6. REPRESENTATIONS, WARRANTIES AND INDEMNITIES

                  (a) MTVN's Representations and Warranties. MTVN represents and

         authority to enter into and perform this Agreement; the execution,

                           (ii) This Agreement is a legal, valid and binding
         obligation of MTVN enforceable against MTVN in accordance with its
         terms, except (x) as such enforceability may be limited by bankruptcy,

         creditors' rights generally and (y) to the extent that equitable
         remedies, such as injunctive relief or specific performance, are within
         the discretion of courts of competent jurisdiction.

MTVN assumes no liability for infringement of third party intellectual property
rights.

                  (b) VLLC's Representations and Warranties. VLLC represents and
warrants that:

                           (i) VLLC is a limited liability company duly formed,
         validly existing and in good standing as a limited liability company
         under the laws of the State of Delaware and has the requisite limited
         liability company power and authority to own, lease and operate its
         assets and its businesses as currently being conducted.

                           (ii) VLLC has the requisite limited liability company

         insolvency or other similar laws affecting the enforcement of
         creditors' rights generally and (ii) to the extent that equitable

                  (c) Indemnification.

                           (i) Each party indemnifies and holds the other party
         and their respective Affiliates and the officers, directors,
         shareholders, employees and agents of any of the foregoing (the
         "Indemnified Parties") harmless against any liability, losses, damages,
         penalties, claims, actions, suits, judgments or settlements of any
         nature or kind (including reasonable costs of investigation, reasonable
         attorneys', accountants' and expert witnesses' fees, and reasonable
         expenses payable to third parties) incurred by any such Person by
         reason of the untruth of or any breach of such party's representations
         and warranties contained herein or any failure by such party to perform
         any agreement or covenant contained in this Agreement.

                           (ii) For purposes of this Section 6(c), any Person or
         entity liable to indemnify an Indemnified Party shall be known as an
         "Indemnifying Party". The Indemnified Party shall notify the
         Indemnifying Party as soon as practicable after the Indemnified Party
         receives notice of or otherwise has actual knowledge of such claim, and
         shall provide to the Indemnifying Party as soon thereafter as
         practicable all information and documentation necessary to support and
         verify the claim being asserted, and the Indemnifying Party shall be
         given access to all books and records in the possession or control of
         the Indemnified Party which the Indemnifying Party reasonably
         determines to be related to such claim.

                                                                              14

                           (iii) Promptly after receipt by an Indemnified Party
         of notice of the commencement by any Person of any action, suit or
         proceeding which might result in the Indemnifying Party becoming
         obligated to indemnify or make any other payment to the Indemnified
         Party under this Section 6(c), the Indemnified Party shall, if a claim
         in respect thereof is to be made against the Indemnifying Party
         pursuant to this Section 6, notify the Indemnifying Party promptly in
         writing of the commencement thereof. The failure of the Indemnified
         Party to so notify the Indemnifying Party shall not relieve the
         Indemnifying Party from any liability which it may have on account of
         this indemnification or otherwise, except to the extent that the
         Indemnifying Party is materially prejudiced thereby. The Indemnifying
         Party shall have the right, within thirty days after being so notified,
         to assume the defense (at its expense) of such action, suit or
         proceeding with counsel reasonably satisfactory to the Indemnified
         Party; provided, however, that VLLC, as the Indemnifying Party, shall
         have no right to so assume, and MTVN shall have the sole right to so
         assume (at the expense of VLLC), the defense of any such action, suit
         or proceeding to the extent such action, suit or proceeding relates to
         intellectual property rights in the MTV Programming. In any such
         action, suit or proceeding the defense of which the Indemnifying Party
         shall have so assumed, the Indemnified Party shall have the right to
         participate therein and retain its own counsel at its own expense;
         provided, however, that such Indemnified Party's counsel shall be
         retained at the Indemnifying Party's expense if (A) the Indemnified
         Party and the Indemnifying Party so agree or (B) the named parties to
         any such action, suit or proceeding (including the impleaded parties)
         include both the Indemnified Party and the Indemnifying Party and
         representation of both the Indemnified Party and the Indemnifying Party
         by the same counsel would be inappropriate due to actual or potential
         differing interests between them. The Indemnifying Party shall promptly
         defend any claim subject to indemnification hereunder, but no
         Indemnifying Party shall settle any claim without the prior approval of
         the Indemnified Party, which approval shall not be unreasonably
         withheld. To the extent that the settlement of such an action or
         proceeding, the defense of which has been assumed by the Indemnifying
         Party, involves payment of money, the Indemnifying Party shall have the
         right, in consultation with the Indemnified Party, to settle those
         aspects dealing only with the payment of money. Notwithstanding the
         foregoing, in connection with any such defense or settlement (which
         defense has been assumed by the Indemnifying Party in accordance with
         this clause (iii)), the Indemnifying Party shall not enter into a
         consent decree or consent to judgment involving injunctive or other
         non-monetary relief or consent to an injunction without the Indemnified
         Party's written consent, which consent shall not be unreasonably
         withheld. The Indemnified Party shall cooperate, and shall use its
         reasonable best efforts to cause its employees and the employees of any
         of their respective wholly owned subsidiaries (in the case of VLLC) or
         Controlled Affiliates (in the case of MTVN) to cooperate with the
         Indemnifying Party in the defense of any action, suit or proceeding
         assumed by the Indemnifying Party. Notwithstanding any and all of the
         foregoing, to the extent that any claim arises out of or is related to
         the MTV Programming, any intellectual property rights therein, or any
         use of the MTV Programming, Licensor shall have the sole right to
         select counsel for the defense of such claim and to control the
         defense, settlement or compromise of such claim.

                           (iv) Each Indemnifying Party's obligation under this
         Section 6(c) shall (A) not affect the other party's right to seek any
         remedy upon a default by the Indemnifying Party under this Agreement
         and (B) survive the termination for any reason of this Agreement.

                          SECTION 7. REQUIRED INSURANCE

                  (a) Liability Insurance. At all times during the term of this
Agreement, VLLC shall provide and maintain at VLLC's sole cost and expense,
general public liability insurance protecting VLLC and MTVN against claims
brought in connection with the Business in an amount not less than Five Million
Dollars ($5,000,000.00) per occurrence, combined single limit, and designating
MTVN as an additional insured.

                  (b) Certificate of Insurance. A certificate of the policy
required to be provided by VLLC pursuant to Section 7(a) shall be delivered to
MTVN within thirty (30) days after the execution of this Agreement. Said
insurance policy shall be timely renewed, and upon each renewal VLLC shall
deliver a renewal Certificate of Insurance to MTVN prior to the expiration date
of the existing term of the said policy. Should VLLC fail to supply MTVN with
such certificate or renewal certificate within the foregoing time limits,
provided that MTVN has given written notice to VLLC and VLLC has failed to
provide such certificate within ten (10) days after such notice, MTVN may, in
VLLC's name and on VLLC's behalf, provide any such insurance as to which such
certificates are not supplied and MTVN shall be reimbursed forthwith by VLLC for
all sums so expended.

                       SECTION 8. TERMINATION OF AGREEMENT

                  (a) This Agreement may be terminated by the mutual written
consent of MTVN and the Partnership.

                  (b) This Agreement shall terminate automatically in the event
of (i) expiration or termination of the Trademark License Agreement for any
reason whatsoever, or (ii) any insolvency of VLLC or its permitted assignee or
upon the appointment of any receiver, administrator, liquidator, or trustee to
take possession of the properties of VLLC or its permitted assignee or upon the
winding-up, sale, consolidation, merger or any sequestration by a Governmental
Entity of VLLC or its permitted assignee.

                  (c) In the event that the use of any of the MTV Programming is
determined to infringe intellectual property rights of others in any given

terminate this Agreement as to any such MTV Programming in such country or
jurisdiction upon notice to VLLC.

                  (d) MTVN may terminate this Agreement in the event of a breach
of any material provision hereof by VLLC, including but not limited to the
provisions of Sections 2, 3, 4, 5, 6, and 10, provided that MTVN has given VLLC

identified the nature of the breach, and within the thirty

                                                                              16

(30) day notice period VLLC has failed to cure the asserted breach; provided,
however, that if any such event shall occur and remain uncured after such
initial 30 day cure period, then, if at the time of such breach, MTVN owned a
majority of outstanding equity ownership of Licensee and at such time the Tune
Stockholder Group met the Tune Minimum Condition (as defined in the Partnership
Agreement) then, MTVN shall give further written notice thereof to the Tune
Stockholder Group and VLLC, and Tune shall in accordance with the provisions of
the Partnership Agreement have an additional period of thirty (30) days to
effect such cure and MTVN shall not be entitled to terminate this Agreement
until the conclusion of such additional 30 day cure period.

                  (e) Upon expiration or termination of this Agreement for any
reason, VLLC shall execute any documents requested by MTVN to confirm the
ownership by MTVN or any of its wholly owned subsidiaries of its right, title
and interest in and to any of the MTV Programming, and immediately cease all
uses of the MTV Programming. In addition, VLLC shall deliver as soon as
reasonably practicable following the termination of this Agreement for any
reason (but in any event within thirty (30) days of such termination) as
directed by MTVN, all MTV Materials and all other materials on which the MTV
Programming is used by VLLC, including, without limitation, all tapes, disks or
other forms of transmission, or any copies of all or any part thereof, or shall
certify the destruction of all such materials.

                  (f) Upon expiration or termination of this Agreement for any
reason, VLLC's right to use the MTV Programming will terminate immediately, and
this Agreement shall cease except that all obligations of the parties under this
Agreement which accrue or are due with respect to periods prior to, or as of,
such termination or expiration, and all obligations which expressly survive the
expiration or termination of this Agreement shall continue in full force and
effect subsequent to and notwithstanding the expiration or termination of this
Agreement.

                  (g) Upon expiration or termination of this Agreement for any
reason, VLLC shall discontinue immediately all use of the MTV Programming, and
cooperate with MTVN and any of its appointed agents to inform the appropriate
authorities of such termination. All rights in the MTV Programming shall remain
the property of MTVN upon expiration or termination.

         This Agreement and all of the provisions hereof shall be binding upon
and inure to the benefit of the parties hereto and their respective successors
and permitted assigns, but neither this Agreement nor any of the rights,

connection with the Reorganization, the Partnership shall assign all of its
rights and obligations hereunder to the corporate successor to all or
substantially all of the Partnership's assets pursuant to an assignment and
assumption agreement in form and substance reasonably satisfactory to MTVN and

hereunder.

                  (a) VLLC acknowledges that the rights of MTVN hereunder are of
a unique and original character giving them peculiar value, the loss of which
cannot be compensated in damages in an action at law. VLLC further agrees and
acknowledges that, in addition to all other rights that MTVN may have, MTVN
shall be entitled as a matter of right without further notice to VLLC, to obtain
injunctive and/or other equitable relief as may be provided by law against any
threatened, potential or actual breach by VLLC of any of the provisions hereof.

                  (b) All remedies, rights, undertakings, obligations and
agreements contained in this Agreement shall be cumulative and none thereof
shall be in limitation of any other remedy, right, undertaking, obligation or
agreement of any party.

                          SECTION 11. ENTIRE AGREEMENT

agreement and understandings, whether written or oral, with respect to the
subject matter hereof, including the letter agreement dated May 19, 1999 among
Viacom International Inc., Liberty Media Corporation, and TCI Music, Inc.

                            SECTION 12. COUNTERPARTS

                  (a) Each party hereby irrevocably and unconditionally submits,

party hereby irrevocably waives, to the fullest extent permitted by law, the
defense of an inconvenient forum to the maintenance of such suit, action or
proceeding in any such court and further waives the 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.

                       SECTION 16. THIRD PARTY BENEFICIARY

         For so long as the Tune Stockholder Group meets the Tune Minimum
Condition, TCI Music shall be a third party beneficiary of MTVN's obligations to
the Partnership hereunder insofar as and only to the extent that it shall be
entitled to enforce the Partnership's rights hereunder in a separate cause of
action for the benefit of the Partnership. The Partnership shall indemnify and
hold harmless TCI Music from and against any costs and expenses (including
reasonable attorneys' fees) incurred by it in pursuing such a cause of action if
such cause of action is resolved in favor of the Partnership and/or TCI Music.
Except as set forth in the first sentence of this Section 16, this Agreement is
for the sole benefit of the parties hereto and their respective successors and
permitted assigns and nothing herein, express or implied, is intended to or
shall confer upon any Person other than such parties any legal or equitable
right, benefit or remedy of any nature whatsoever under or by reason of this
Agreement.

              SECTION 17. CONSENTS AND APPROVALS; WAIVERS; REMEDIES

         All consents and approvals which may be given under this Agreement
shall, as a condition of their effectiveness, be in writing. The granting by a
party hereto of any consent to or approval of any act requiring consent or
approval under the terms of this Agreement, or the failure on the part of a
party to object to any such action taken without the required consent or
approval, shall not be deemed a waiver by the party whose consent was required
of its right to require such consent or approval for any other act. The
observance of any provision 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.

                              SECTION 18. SURVIVAL

         The provisions contained in this Agreement in Sections 2(f), 2(g),
4(c), 5, 6, 10, 13, 14, 15, 16, 20 and this Section 18 shall survive the
termination of this Agreement.

                            SECTION 19. 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
<PAGE>   20
                                                                              20

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.

                        SECTION 20. RULES OF CONSTRUCTION

                  (a) The definitions in this Agreement shall apply equally to

neuter forms.

                  (b) The words "include", "includes" and "including" shall be
deemed to be followed by the phrase "without limitation".

                  (c) The words "herein", "hereof" and "hereunder" and words of

require.

                  (d) Unless the context shall otherwise require, any references
to any agreement or other instrument or statute or regulation are to it as
amended and supplemented from time to time (and, in the case of a statute or
regulation, to any successor provisions).

                  (e) Any reference in this Agreement to a "day" or number of
"days" (without the explicit qualification of "Business") shall be interpreted
as a reference to a calendar day or number of calendar days. If any action or
notice is to be taken or given on or by a particular calendar day, and such
calendar day is not a Business Day, then such action or notice shall be deferred
until, or may be taken or given on, the next Business Day.

                  (f) 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.

                              SECTION 21. AMENDMENT

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

                            SECTION 22. FORCE MAJEURE

         In the event that during the Term, either party is unable to perform
its obligations under this Agreement by reason of causes beyond its reasonable
control including but not limited to civil or industrial disturbances, acts of
God, strikes, floods, natural disasters, riots, insurrections,
<PAGE>   21
                                                                              21

embargoes, blockages, restrictions or regulations or orders of any Governmental
Entity, then such non-performance shall not be deemed to be a breach of this
Agreement and shall be deemed excused but only for so long as the causes of such
non-performance shall remain in effect; provided, however, that the party so
affected shall use its reasonable best efforts to avoid or remove such causes of
nonperformance and shall continue performance hereunder with the utmost dispatch
whenever such causes are removed. In the event the force majeure event(s) result
in the non-performance of this Agreement for a continuous two-year period (the
"Force Majeure Period"), this Agreement shall then terminate with respect to the
jurisdiction(s) in the Territory affected by such force majeure event(s);
provided, however, that such termination shall not become effective until MTVN
has provided VLLC with ten (10) days prior written notice of such termination.
Such notice may be provided to VLLC any time after the Force Majeure Period.

                        SECTION 23. HEADINGS AND CAPTIONS

                          SECTION 24. 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 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 WITNESS WHEREOF, the parties hereto have executed and delivered this
Agreement as of the day and year first above written.

assign's Controlled Affiliates. Such promotion shall be for no consideration
payable by VLLC or its permitted assigns and includes advertising, VJ mentions,
text on screen, web links or other promotional support by MTV, VH1 and any other
programming service that MTVN Controls, in a manner and in amounts to be
determined by MTVN in its sole discretion; provided that such promotion shall be
(x) vigorous, to the extent consistent with MTVN's normal operation of its
businesses other than the Business, and (y) generally consistent in overall
effort with promotions provided by other similarly situated media companies in
relation to the promotion of the internet businesses of their subsidiaries and
Affiliates. During the period commencing on the date hereof until the fifth
anniversary of the date hereof, such promotion shall have an aggregate fair
market value of not less than $100 million, as valued by the CEO of VLLC or its
permitted assign (or if the CEO has a conflict of interest due to arrangements
between the CEO and MTVN, the most senior officer of VLLC or its permitted
assign not so conflicted). For purposes of the foregoing, Mr. Fred Seibert shall
not, for as long as he is CEO of the Partnership, be deemed to have a conflict
of interest so long as no material part of his compensation is directly
dependent on the performance of MTV, VH-1 or any programming service that MTVN
Controls. All promotional services provided by MTVN pursuant to this Section
2(a) shall be in accordance with, and shall not violate, any laws, rules or
regulations of any Governmental Entity, and the provision of such promotional
services shall not violate the rights of any third party.

                  (b) During the term of this Agreement, VLLC shall pay to MTVN
a promotion fee of $5,000,000 per calendar quarter which amount shall be payable
on the last

                                                                               3

business day of each calendar quarter and shall be the sole consideration
payable by VLLC for the promotional activities described in Section 2(a).

         3. Term. The term of this Agreement shall commence on the date hereof,
and unless earlier terminated pursuant to Section 6 hereof, terminate on the
later of (x) the fifth anniversary of the date hereof or (y) the second
anniversary of the first date that the MTVN Stockholder Group owns in the
aggregate less than 50% of the outstanding equity interests of VLLC or its
permitted assign.

         4. VLLC Obligations. VLLC will, at no cost to MTVN, promote the
programming services of MTVN in a reasonable manner requested by MTVN subject to
the approval not to be unreasonably withheld of the CEO of VLLC or its permitted
assign (or if the CEO has a conflict of interest due to arrangements between the
CEO and MTVN, the most senior officer of VLLC or its permitted assign, not so
conflicted. For purposes of the foregoing, Mr. Fred Seibert shall not, for as
long as he is CEO of the Partnership, be deemed to have a conflict of interest
so long as no material part of his compensation is directly dependent on the
performance of MTV, VH-1 or any programming service that MTVN Controls.

         5. Indemnification.

                  (a) Each party shall at all times defend, indemnify and hold
the other party, its Affiliates, officers, directors, agents and employees
harmless from and against any and all liabilities, costs, losses or expenses,
including reasonable attorneys' fees, it or they may incur by reason of any
third-party claim or suit arising solely in connection with (i) such other
party's use of the indemnifying party's material provided to such other party
for promotional purposes pursuant to this Agreement or (ii) such indemnifying
party's gross negligence, willful misconduct or willful breach of this
Agreement; provided, however, that VLLC (or its permitted assign) shall not be
required to indemnify MTVN to the extent such claim arose from an act or
omission of VLLC (or its permitted assign) made at the request of MTVN for
MTVN's sole benefit. Each party agrees to promptly notify the other party in
writing of an indemnifiable claim, but the failure to so notify shall not
relieve an indemnifying party of any liability which it may have to an
indemnified party except to the extent the indemnifying party is materially
prejudiced by the failure to give such prompt notice.

                  (b) An indemnifying party shall have the right to participate
in and assume the defense of any such third party claim for which
indemnification is sought. The party claiming indemnification shall have the
right to employ separate counsel in any such action and to participate in the
defense thereof but the fees and expenses of such separate counsel shall not be
at the expense of the party against whom indemnification is sought 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
indemnifying party shall not have the right to direct the defense of such action
on behalf of the indemnified party, and the indemnifying party
<PAGE>   4
                                                                               4

shall pay the reasonable fees and expenses of the indemnified party's counsel.
Except as otherwise provided above, a party obligated to provide indemnification
under Section 5(a) 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.

                  (c) An indemnifying party shall not be liable for any
settlement of any proceeding effected without its written consent (which consent
shall not be unreasonably withheld), but if settled with such consent, or if
there be a final judgment for the plaintiff, the indemnifying party shall
indemnify and hold harmless the 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
indemnifying 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.

         6. Termination.

                  (a) Either party may terminate this Agreement in the event of
a material breach by the other party, provided that (i) such party has given the
breaching party thirty (30) days written notice of such breach, identified the
nature of the breach, and within such thirty-day cure period the breaching party
has failed to cure the asserted breach and (ii) this Agreement may not be
terminated due to VLLC's failure to make any payment contemplated by Section
2(b). The parties agree that for so long as the MTVN Stockholder Group (x) owns
at least 50.1% of the outstanding equity interests of the Partnership or (y) is
entitled to designate pursuant to the Partnership Agreement a majority of the
Management Committee of the Partnership or, following the Reorganization, a
majority of the Board of Directors of the corporate successor to the
Partnership, MTVN shall not have any right to terminate this Agreement under
this Section 6(a) as a result of or based upon any breach by the Partnership of
this Agreement.

                  (b) MTVN may terminate this Agreement upon 10 days prior
notice in the event that TCI Music and its subsidiaries cease to own an equity
interest in the Partnership.

                  (c) By either party upon written notice to the other party if
such other party shall file a petition in bankruptcy or insolvency, or a
petition for reorganization or adjustment of debts or for the appointment of a
receiver or trustee of all as a substantial portion of its property, or shall
make an assignment for the benefit of creditors, or if a petition in bankruptcy
or other petition described in this paragraph is filed against such other party
and shall not be discharged within 60 days thereafter.

         7. Notices. Except as expressly provided herein, notices and other
communications provided for herein shall be in writing and shall be delivered by
hand or overnight courier service, mailed (certified or registered mail, postage

or to such other address or attention of such other party or Person as any party
shall advise the other party in writing. All notices and other communications
given to a party in accordance with the provisions of this Agreement shall be
deemed to have been given (i) three Business Days after the same are sent by
certified or registered mail, postage prepaid, return receipt requested, (ii)
when delivered by hand or transmitted by facsimile (confirmation received)
unless delivered on a day which is not a Business Day or after 5:00 p.m., local
time, at the place of receipt, in which case such notice shall be deemed to have
been given on the next succeeding Business Day or (iii) one Business Day after
the same are sent by a reliable overnight courier service, with acknowledgment
of receipt.

         8. Force Majeure. No failure or omission by a party hereto in the
performance of any of its obligations under this Agreement shall be deemed a
breach of this Agreement nor shall it create any liability, if the same shall
arise from any cause or causes beyond the control of the party, including, but
not limited to, the following, which, for the purpose of this Agreement, shall
be regarded as beyond the control of the party in question: acts of God, acts or
omissions of any government, any rules, regulations, or orders issued by any
Governmental Entity, fire, storm, flood, earthquake, accident, war, rebellion,
insurrection, riot, invasion, strikes and lockouts; provided, however, that the
party so affected shall use its reasonable best efforts to avoid or remove such
causes of nonperformance and shall continue performance hereunder with the
utmost dispatch whenever such causes are removed.

         9. Waiver of Default. No consent or waiver, express or implied, by
either party with respect to any breach or default by the other party hereunder
shall be deemed or construed to be a consent or waiver with respect to any other
breach or default by any party of the same provision or any other provision of
this Agreement. No waiver of any provision of this Agreement shall be effective
unless in writing and signed by the party against which enforcement thereof is
to be sought. Failure on the part of a party to complain of any act or failure
to act of the other party or

                                                                               6

to declare such party in default shall not be deemed or constitute a waiver of
any rights hereunder.

         10. Assignment. This Agreement and all of the provisions hereof shall
be binding upon and inure to the benefit of the parties hereto and their
respective successors and permitted assigns, but neither this Agreement nor any
of the rights, interests or obligations hereunder shall be assigned by any party
hereto (whether by operation of law or otherwise) without the prior written
consent of the other party hereto except that immediately after the execution of
this Agreement as part of VLLC's initial contribution to the Partnership, VLLC
shall assign all of its rights and obligations hereunder (other than its
obligation under Section 2(b)) to the Partnership and the Partnership shall
accept and assume the same in accordance with the terms of the VLLC
Contribution, Assignment and Assumption Agreement dated as of the date hereof
between VLLC and the Partnership, whereupon the Partnership shall be substituted
for VLLC in all respects (other than Section 2(b)) as fully as if it had been an
original party hereto. Upon such assignment and assumption, VLLC shall be
released from all of its obligations hereunder other than under Section 2(b). In
connection with the Reorganization, the Partnership shall assign all of its
rights and obligations hereunder (but not VLLC's obligations under Section 2(b))
to the corporate successor to all or substantially all of the Partnership's
assets pursuant to an assignment and assumption agreement in form and substance
reasonably satisfactory to MTVN and such corporate successor, and such corporate
successor shall accept and assume the same. Upon such assignment and assumption,
the Partnership shall be released from all of its obligations hereunder.

         11. Governing Law. This Agreement shall be governed by, and construed
and enforced in accordance with, the laws of the State of New York, without
giving effect to any of its conflicts of law provisions.

         12. Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall be considered one and the same agreement, and
shall become effective when one or more counterparts shall have been signed by
each party and delivered to the other party.

         13. Headings. The headings of the sections of this Agreement are for
convenience of reference only and shall not modify, define or limit any of the
terms or provisions of this Agreement.

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

         15. Entire Agreement. The provisions of this Agreement set forth the
entire agreement and understanding between the parties as to the subject matter
hereof and supersede all prior agreements, oral or written, and other
communications between the parties hereto or among the parties to the MOU (as
defined below) relating to the subject matter hereof, including the letter
agreement ("MOU") dated May 19, 1999 among Viacom, Liberty and TCI Music.

                                                                               7

         16. 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.

         17. 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, including without limitation
throughout Section 2(b), 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.

         18. Specific Performance. The rights of the parties under this
Agreement are unique and, accordingly, the parties shall have the right, in
addition to such other remedies as may be available to any of them at law or in
equity, to enforce their rights hereunder by actions for specific performance.

         19. Third Party Beneficiary. For so long as the Tune Stockholder Group
is entitled to designate a Representative to the Management Committee of the
Partnership pursuant to the Partnership Agreement, TCI Music shall be a third
party beneficiary of MTVN's obligations to the Partnership hereunder insofar as
and only to the extent it relates to the right to enforce on behalf of the
Partnership the Partnership's rights hereunder in a separate cause of action for
the benefit of the Partnership. The Partnership shall indemnify and hold
harmless TCI Music from and against any costs and expenses (including reasonable
attorneys' fees) incurred by it in pursuing such a cause of action if such cause
of action is resolved in favor of the Partnership and TCI Music. Except as set
forth in the first sentence to this Section 19, this Agreement is for the sole
benefit of the parties hereto and their respective successors and permitted
assigns and nothing herein, express or implied, is intended to or shall confer
upon any other Person any legal or equitable right, benefit or remedy of any
nature whatsoever under or by reason of this Agreement.
