Item 5.           OTHER EVENTS

         On May 19, 1999, MTV Networks, a division of Viacom International Inc.
("MTVN") and the Company entered into a binding Letter Agreement to form and
operate MTVN Online L.P., a Delaware limited partnership ("Music.co").
Music.co's business will be to develop, operate, manage, market, distribute and
license text, audio and video music, music-related and music-themed services
online and engage in reasonably related activities, including e-commerce
applications and consumer oriented commercial transactions (the "Business").
With certain exceptions (the "Excluded Assets"), the Company has agreed to cause
its subsidiaries SonicNet, Inc. and The Box Worldwide Inc. to contribute to
Music.co substantially all of their respective assets and businesses, and the
stock of their respective subsidiaries which exclusively conduct their
respective international businesses. MTVN will contribute to Music.co the assets
and businesses owned or controlled by it that constitute all of its current or
planned assets and businesses engaged, or to be engaged, exclusively in the
Business, including those assets and businesses used exclusively in connection
with the MTV.com, VH1.com and Imagine Radio businesses, and all wholly owned
international assets and businesses engaged exclusively in the Business. For
their respective contributions, the Company (including Box and SonicNet) will
receive an aggregate 10% limited partnership interest in Music.co and MTVN will
receive an aggregate 90% general and limited partnership interest in Music.co.
With respect to the Excluded Assets, Music.co will provide Box or SonicNet, as
applicable, with certain products and services so that the Company may comply
with its commitments with respect to such assets.

         Music.co will also receive a royalty-free license to use certain of the
brandnames, logos, tradenames and trademarks of MTV and VH1, and a royalty-free,
with certain exceptions, license to use certain intellectual property and
technology of MTV and VH1, in each case in connection with the Business. The
foregoing license will generally be an exclusive license with respect to the
Business.

         MTVN has also agreed to promote the Business on MTV and VH1 until the
later of five years from the closing of the transactions contemplated by the
Letter Agreement (the "Closing") or two years after MTVN and its affiliates
cease to own at least 5% of the equity in Music.co. This promotional agreement
will terminate earlier if the Company ceases to own any equity investment in
Music.co. Such promotion over the five-year period from the Closing has an
aggregate market value of at least $100 million.

         The Company will not be required to make any contributions to Music.co
in excess of $10 million, which includes amounts expended to fund the assets
being contributed from the date of the Letter Agreement to the Closing.

         The Company will be entitled to designate one member of the management
committee of Music.co and will have certain approval rights with respect to
enumerated actions by Music.co, subject to certain conditions.




<PAGE>   3

         The Letter Agreement states the parties' intention that Music.co become
a public company within two years after the Closing. If the stock of Music.co
that the Company would receive for its partnership interest would have an
aggregate value of less than a specified amount at the time of the initial
public offering of Music.co based on the offering price to the public in such
offering, then Music.co is obligated to make such adjustments as may be
necessary to cause the Company's Music.co shares to have an aggregate value
(based on the public offering price) of at least the specified amount or to
represent at least 15% of the outstanding Music.co shares, whichever results in
the issuance of the fewest shares. If the initial public offering of Music.co
has not occurred by the second anniversary of the Closing (subject to a 60-day
extension under certain circumstances), an equivalent provision will apply to
adjust the Company's partnership interest in Music.co based on the fair market
value of Music.co, on a going concern or liquidation basis, whichever yields the
higher valuation, determined through an appraisal process.

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

         MTVN has agreed that, subject to certain exceptions, if MTVN, directly
or through a controlled affiliate, acquires, makes an investment in or otherwise
operates the Business other than through Music.co at any time during the
five-year period following the Closing, it will provide the Company the right to
purchase a pro-rata interest in such business or assets so long as certain
conditions as to the Company's equity interest in Music.co are satisfied. MTVN
has also agreed, for the same period, not to promote the Business as owned or
operated by any of its affiliates (other than Music.co) on any of its cable
television services except on commercial terms.

         The Letter Agreement may be terminated by mutual consent of the
parties; by any party not in material breach of its obligations if the Closing
has not occurred by July 15, 1999; by any party if consummation of the
transactions has been enjoined by a final non-appealable order, or by any party
if the conditions to its obligations to close are impossible to satisfy,
provided that such party has not breached it obligations under the Letter
Agreement so as to render it impossible to satisfy the conditions to its
obligations to close.

         The Letter Agreement also contains other customary terms and conditions
in an agreement of this type.

         In connection with the negotiation of the Letter Agreement, the Company
entered into an agreement dated May 18, 1999, with AT&T Broadband & Internet
Services, Inc. ("AT&T Broadband"), as an inducement to AT&T Broadband to enter
into a revised affiliation agreement with MTVN for the distribution of MTVN's
services on AT&T Broadband cable systems. AT&T Broadband's entering into this
agreement was a condition of MTVN entering into the Letter Agreement. Pursuant
to this agreement, on the first to occur of the closing of Music.co's initial
public offering and the second anniversary of the Closing under the Letter
Agreement (or the fifth anniversary of the Closing, if extended by AT&T
Broadband because the public offering has not occurred by the second anniversary
of the Closing), the Company will become obligated to pay AT&T Broadband an
amount equal to 10% of the Excess Value (as defined below) of its equity
interest in Music.co, but in no event more than $30 million, nor less than $15
million. The Excess Value means the amount by which (a) the average market price
or appraised fair market value of the Company's equity interest in Music.co
exceeds (b) the sum of (x) the lesser of a specified amount and the value
determined pursuant to the Letter Agreement for purposes of determining whether
to adjust Music.co's interest and (y) any additional capital contributions made
by the Company to Music.co. The Company may pay such amount in cash or shares of
its Series A Common Stock (valued at market). AT&T Broadband also agreed to
negotiate in good faith to enter into an agreement with the Company or a joint
venture between the Company and Music.co for AT&T Broadband to provide and
enable the functionalities necessary to provide to AT&T digital subscribers an
interactive music and music-related transaction/commerce channel to be developed
by the Company or such joint venture.

A copy of the Letter Agreement is included as Exhibit 2.1, a copy of the
agreement with AT&T Broadband is included as Exhibit 10.42 and a copy of the
Company's and Viacom's press release with respect to the Letter Agreement is
included as Exhibit 99.1 to this Form 8-K. Such documents are incorporated by
reference into this Item 5, and the foregoing description of such documents is

                           (i)      If the approval of the Federal
                                    Communications Commission ("FCC") of the
                                    transfer of the low power television station
                                    licenses from Box to Music.co has not been
                                    obtained by the Closing, such licenses will
                                    not be transferred until such approval is
                                    received and Box and Music.co will enter
                                    into a customary LMA agreement for
                                    situations similar to this situation
                                    pursuant to which, to the extent legally
                                    permissible, Music.co will retain all
                                    revenues and bear all expenses and
                                    liabilities attributable to such stations
                                    and which LMA agreement will remain in
                                    effect until the applicable FCC approvals
                                    are obtained; and

                           (ii)     If approval by Argentine governmental
                                    authorities ("Argentine Approval") of the
                                    transfer of Box Argentina, S.A. ("Box
                                    Argentina"), is required and has not been
                                    obtained by the Closing, then Box Argentina,
                                    S.A. will not be transferred until such
                                    approval is obtained and, if legally
                                    permissible under Argentine law, Box and
                                    Music.co will enter into an agreement
                                    pursuant to which Music.co will operate Box
                                    Argentina and will retain all revenues and
                                    bear all expenses and liabilities
                                    attributable to Box Argentina until the
                                    applicable Argentine Approval is obtained;
                                    provided that if such arrangement is not
                                    legally permissible, the parties will enter
                                    into another mutually satisfactory
                                    arrangement.

         4. Access to Information. Prior to Closing, each of Tune and MTVN shall
make available to each other during regular business hours and upon reasonable
prior notice all books and records relating to the MTVN Contribution and the
Tune Contribution regardless of location (and except as otherwise provided
herein, all other books and records which have material information relating to
the MTVN Contribution and the Tune Contribution and which a reasonable person
would anticipate reviewing in connection with the transactions contemplated by
this Music.co Agreement) (the "Confidential Information"). Each party shall be
obligated to maintain the confidentiality of the Confidential Information in
accordance with the terms and conditions set forth in the Term Sheet. In
addition, prior to the Closing Tune shall cause Box and SonicNet to provide MTVN
with reasonable access to all employees of Box and SonicNet and otherwise
cooperate with and assist MTVN in conducting MTVN's due diligence relating to
Box and SonicNet. To the extent requested by MTVN, prior to the Closing Tune
shall also provide MTVN with reasonable access to all employees of Tune who are
engaged in the businesses of Box or SonicNet.

         5. Assignability. This Music.co Agreement and the Definitive
Agreements, including the right to form Music.co hereunder, may be fully
assigned by (i) MTVN to one or more affiliates of MTVN which is directly or
indirectly wholly-owned (and including for this purpose Imagine Radio) by Viacom
Inc., provided that MTVN guarantees, to Tune's reasonable satisfaction,
performance of such assignee's obligations hereunder and thereunder and (ii)
Tune

                                                                               4


to any of its wholly-owned subsidiaries, so long as such entities remain
wholly-owned subsidiaries of Tune and that Tune guarantees, to MTVN's reasonable
satisfaction, performance of such assignee's obligations hereunder and
thereunder. Any assignment by any party hereto in violation of this Section 5
shall be null and void ab initio.

         6. Definitive Agreements. MTVN will prepare the initial drafts of, and
MTVN, Tune and Liberty shall use their reasonable best efforts to enter into,
contribution agreements, a limited partnership agreement, the License Agreement,
the Promotion Agreement, the Services Agreement, Box License Agreement, a
Liberty, MTVN and Tune parent agreement and guarantee (with no Liberty guarantee
of Tune's obligations) and other agreements required to reflect the terms
described herein, including related schedules, each of which shall reflect the
terms set forth herein or in the Term Sheet, and further containing such other
terms as are customary and appropriate in connection therewith (collectively,
the "Definitive Agreements") on or before the Closing date established pursuant
to Section 2 hereof; however, the parties hereto agree that this Music.co
Agreement contains the principal terms and conditions of the transactions
contemplated hereby and that it shall be binding upon and enforceable by the
parties hereto with respect to the matters covered hereby until a Definitive
Agreement is signed which covers all or a portion of such matters, at which time
this Music.co Agreement will no longer apply to the matters covered by such
Definitive Agreement (but will continue to govern with respect to any matters
not covered by such Definitive Agreement unless otherwise expressly provided in
such Definitive Agreement). At such time as Definitive Agreements are executed
which cover all matters covered hereby or state that they are intended to be
exclusive of all matters covered hereby, this Music.co Agreement shall be
terminated and shall be of no further force or effect. Accordingly, whether or
not any or all of the Definitive Agreements are executed, MTVN, Tune and Liberty
shall consummate the Closing on the basis and subject to the conditions set
forth in this Music.co Agreement, and MTVN, Tune and Liberty shall be bound by
the terms and provisions of this Music.co Agreement to the extent not covered by
any executed Definitive Agreement unless otherwise agreed upon by Tune, Liberty
and MTVN. The Definitive Agreements shall contain (i) the covenants,
representations and agreements contained in this Music.co Agreement, (ii) a
representation by Tune that, as of the date of this Music.co Agreement and as of
the Closing, except for contracts entered into after the date hereof with the
consent of MTVN, neither Music.co nor any of its subsidiaries shall be subject
to any non-competition provision, exclusivity provision, output or requirement
contract or right of first refusal or other similar contractual restrictions on
its ability to conduct its business (collectively, the "Restrictive Provisions")
by virtue of Music.co's assumption either directly or through a subsidiary of
any contract or other arrangement of SonicNet or Box or any of their
subsidiaries or as a result of Music.co being a successor to either SonicNet or
Box, other than such Restrictive Provisions as would apply solely to the Tune
Contribution as the case may be and other than those set forth in the contracts
and arrangements referred to in the Contract Binder Index dated May 18, 1999
attached as Schedule I and (iii) from the appropriate party, customary
representations regarding title to the assets being contributed to Music.co,
sufficiency of assets being contributed and/or services or assets being made
available to Music.co, corporate authority, no conflicts, contracts, historical
financial statements and intellectual property rights, since December 31, 1998
no event of material adverse change for Box or SonicNet (other than the Material
Adverse Change Exclusions), and other customary representations for transactions
of this type, subject to customary qualifications (including (whether or not
customary) exceptions for nonassignment and change in control provisions
(including the effect of the failure to obtain a

                                                                               5


waiver of or consent under any such provision), the matters referred to in
paragraph 3(c), and any other matters expressly disclosed to the other party in
writing prior to the execution of this Music.co Agreement) (collectively, the
"Customary Representations"), which Customary Representations shall be made as
of the date of this Music.co Agreement and as of the Closing, (iv) covenants
requiring MTVN to operate the businesses included in the MTVN Contribution, and
Tune to cause Box and Sonic Net to operate the businesses included in the Tune
Contribution, in a manner consistent with this Music.co Agreement, and other
customary covenants for transactions of this type, including covenants to
cooperate in obtaining required third party approvals, but excluding any
covenants not to compete or similar covenants other than the covenants contained
in the Term Sheet under the headings "Non-Compete" and "Exclusivity"
(collectively, the "Customary Covenants"), (v) customary indemnities from the
applicable party relating to the representations (including the Customary
Representations) and covenants (including the Customary Covenants) made or
deemed made herein (it being understood that indemnities as to contributions
shall be made to Music.co and that indemnities by Liberty shall relate only to
its obligations arising under the heading "Non-Compete" in the Term Sheet or in
the applicable Definitive Agreement), which indemnity for representations
(including the Customary Representations and the representation of Tune
contained in clause (ii)) will be subject to a $1.75 million tipping basket and
a $150 million cap (provided that once such tipping threshold is met, the
indemnifying party will be liable for the first dollar and up to the full $150
million cap hereunder) (collectively, the "Customary Indemnities"), (vi)
customary indemnities by Music.co to the applicable contributing party with
respect to the performance of contracts assigned to and obligations assumed by
Music.co and the operation of the contributed businesses after the Closing,
except that Music.co shall not be obligated to indemnify any contributing party
with respect to obligations to the extent that they relate to pre-Closing
periods (other than accounts payable, accrued expenses, prepayments and similar
working capital items) 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) of an assigned contract (the "Music.co Indemnity"), and (vii) other
terms customary for transactions of this type (collectively, the "Other
Customary Terms"). Without limitation of the foregoing, from the date thereof
through the consummation of the Closing or the earlier termination of this
Music.co Agreement in accordance with its terms, Tune agrees that it will not
permit (x) SonicNet or Box or any of their subsidiaries to enter into or renew
any affiliation agreement or amend any of the terms of any existing affiliation
agreement which is part of the Tune Contribution without the prior written
consent of MTVN, (y) Box or any of its subsidiaries to exercise its option under
any existing affiliation agreement to roll out Box Service onto any cable or
other system, and (z) Box or SonicNet or any of their subsidiaries to enter
into, renew or amend any agreement involving any significant expenditure or
obligation which Music.co. would be obligated to pay or bear after the Closing.
Notwithstanding the foregoing, Tune shall be permitted to cause SonicNet or Box
to amend their respective agreements or take other actions, but only to the
extent necessary to effectuate the arrangements referred to in Schedule 1 to the
Term Sheet, to effectuate assignments thereof as contemplated by this Music.co
Agreement and/or to eliminate or limit any Restrictive Provision. The Definitive
Agreements shall not contain any conditions to the obligation of any party to
consummate the Closing other than the conditions set forth in Section 3 hereof.
The parties agree that if and to the extent Definitive Agreements containing the
provisions of this Music.co Agreement and the Customary Representations, the
Customary Covenants, the Customary Indemnities, the Music.co Indemnity, and the
Other Customary Terms (with respect to the transactions contemplated by such
Definitive Agreement) are not executed by all parties prior to

                                                                               6


Closing, this Music.co Agreement shall be deemed to contain the applicable
Customary Representations, the Customary Covenants, the Customary Indemnities,
the Music.co Indemnity, and the Other Customary Terms, which shall be binding
upon and enforceable by the parties hereto as if set forth in Definitive
Agreements. Any dispute regarding the deemed terms of any Definitive Agreement,
including any Customary Representation, Customary Covenant, Customary Indemnity,
the Music.co Indemnity, or Customary Other Term shall be resolved by bringing an
appropriate action before a court of competent jurisdiction referenced in
Section 12. At the Closing or when the Closing is deemed to have occurred,
Liberty and MTVN will deliver a writing (the "SSI Notice") to Satellite
Services, Inc. ("SSI") notifying SSI that the Closing has occurred, thereby
causing the affiliation agreement between SSI and MTVN (the "SSI Affiliation
Agreement") to become effective.

         7. Termination. This Music.co Agreement shall terminate and its
provisions shall become null and void (except for the obligation to maintain the
confidentiality of the Confidential Information contained in Section 4, which
shall survive and remain in full force and effect and except that such
termination shall not relieve any party for any liability for any breach arising
prior to such termination) with respect to all the parties hereto upon the
happening of any of the following:

                  (a) by the mutual written consent of the parties hereto;

                  (b) by any of MTVN, Tune or Liberty if the Closing has not
         taken place by July 15, 1999 and the terminating party is not in
         material breach of its obligations under this Music.co Agreement;

                  (c) by any of MTVN, Tune or Liberty if any court of competent
         jurisdiction has issued a final non-appealable order, stay, injunction
         or decree restraining or prohibiting the consummation of the
         transactions contemplated by this Music.co Agreement; or

                  (d) by any of MTVN, Tune or Liberty if the conditions to such
         party's obligations to consummate the transactions contemplated by this
         Music.co Agreement are impossible to satisfy; provided, that the
         terminating party shall not have breached its obligations under this
         Music.co Agreement and as a result of such breach rendered the
         conditions to its obligations to consummate the transactions
         contemplated by this Music.co Agreement impossible to satisfy.

         8. Specific Performance. The parties recognize the unique nature of the
obligations of each party hereunder and therefore agree that each party shall be
entitled to specific performance of the obligations of the other parties set
forth in this Music.co Agreement, including without limitation the obligation to
deliver the SSI Notice.

         9. Costs and Expenses. Each party shall be solely responsible for the
payment of its own costs and expenses incurred in connection with the
negotiation and closing of the transactions contemplated hereby. Filing fees,
and sales and transfer taxes in connection with the consummation of the
transactions contemplated hereby will be borne by Music.co. Each party
represents and warrants to the other parties that it did not engage the services
of a broker in

                                                                               7


connection with this Music.co Agreement, and each party shall indemnify and hold
the other parties harmless from any breach of the foregoing representation and
warranty.

         10. Disclosure. The parties will mutually agree on the form of any
public announcement or press release to be issued with respect to the subject
matter of this Music.co Agreement; provided, however, that neither party shall
be required to obtain the consent of any other party for any disclosure required
by law or by the rules of any national securities exchange, but such required
disclosure may only be made after there has been meaningful consultation with
the other party.

         11. Counterparts. This letter 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.

         12. Governing Law; Submission to Jurisdiction. This Music.co 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. Each party to this Music.co Agreement hereby irrevocably and
unconditionally: (i) agrees that any suit, action or proceeding against it by
any other party to this Music.co Agreement with respect to this Music.co
Agreement may be instituted, and that any suit, action or proceeding by such
party against any other party with respect to this Music.co Agreement shall be
instituted, only in the Supreme Court of the State of New York, County of New
York, or the U.S. District Court for the Southern District of New York (and
appellate courts from any of the foregoing), as the party instituting such suit,
action or proceeding may elect in its sole discretion, (ii) consents and
submits, for itself and its property, to the jurisdiction of such courts for the
purpose of any such suit, action or proceeding instituted against it by the
other, (iii) 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, and (iv) waives the right to a
jury trial in any such suit, action or proceeding.

         13. Certain Actions. Beginning promptly after the date hereof, the
parties will cooperate to take such action as is necessary to effectuate the
arrangements regarding Excluded Tune Assets as are described on Schedule 1 to
the Term Sheet.

         14. No Presumption. This Music.co Agreement and the Definitive
Agreements 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.

         15. Entire Agreement. This Music.co 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. Each party represents and
warrants to the other parties that (i) it has the requisite corporate power and
authority to execute, deliver and perform this Music.co Agreement, and (ii) this
Music.co Agreement constitutes the legal, valid and binding obligation of such
party and is enforceable against such party in accordance with its terms.

         16. Binding on Viacom. The parties acknowledge that MTVN is a division
of Viacom International Inc. and that consequently Viacom International Inc. is
obligated to perform the obligations to be paid or performed by MTVN hereunder;
provided that the use of the term "MTVN" in the Term Sheet in the sections
entitled "MTVN Contribution," "Officers," and "Exclusivity" shall refer only to
the operating unit or units of Viacom International Inc. that on a day-to-day
basis operate the business of MTV or VH-1.

         17. Tune and Liberty. Each of the obligations under this Music.co
Agreement of Liberty and Tune are several and not joint.

         18. No Solicitation. From the date hereof until the Closing, neither
Liberty, Tune nor any of their Controlled Affiliates (as hereinafter defined)
(other than Box, SonicNet or its subsidiaries) will hire any person that is an
employee of SonicNet or Box or their subsidiaries at anytime during the period
from the date hereof to the Closing without the prior written consent of MTVN.
From the date hereof until the second anniversary of the Closing, neither
Liberty, Tune nor any of their Controlled Affiliates will hire any person who
becomes an employee of Music.co or any of its subsidiaries upon consummation of
the Closing without the prior written consent of MTVN. Neither Liberty, Tune nor
any of their Controlled Affiliates will solicit for employment any employee of
Music.co or any of its subsidiaries for so long as Tune or any of its affiliates
owns an equity interest in Music.co.

         19. Music.co Adherence. As soon as is practicable after organization of
Music.co, MTVN will cause Music.co to execute a counterpart of this Music.co
Agreement becoming a party thereto and accepting all its rights and obligations
hereunder.

         20. Controlled Affiliates. A Controlled Affiliate of any person is an
affiliate as to which such person possesses, directly or indirectly, the
affirmative power to direct or cause the direction of the management and

interests or other ownership interests, by contract, by membership or
involvement in the board of directors, management committee or other management
structure of such affiliate, or otherwise).

                                    Agreement, the licenses granted under the

                                    terms and conditions reasonably necessary to
                                    protect MTVN's ownership of such

                                    promote the programming services of MTVN in

INTERIM OPERATIONS;
FUNDING OBLIGATIONS:


                                    Tune will cause SonicNet and Box to continue
                                    to operate the assets and businesses being
                                    contributed by them prior to the Closing of
                                    the transactions contemplated hereby in the
                                    ordinary course and in accordance with the
                                    budget attached to this Term Sheet (the
                                    "Tune Budget"). MTVN will continue to
                                    operate the assets and businesses being
                                    contributed by it prior to the Closing in a
                                    manner which it reasonably believes will
                                    further the Business of Music.co and which
                                    will not interfere with or frustrate the
                                    transactions contemplated hereby; provided
                                    that (i) if such operations involve a
                                    related party transaction as described below
                                    under the section entitled "Related Party
                                    Transactions" for which a special audit
                                    right is required, then MTVN shall grant
                                    Tune a special audit right as to the
                                    transaction and (ii) such operations will
                                    not require Tune to exceed its $10 million
                                    required capital contribution ceiling. From
                                    the date hereof until the Closing, each of
                                    MTVN and Tune shall and shall cause their
                                    respective subsidiaries to fund its
                                    respective assets and businesses to be
                                    contributed to Music.co with sufficient
                                    capital to fund operations and, in the case
                                    of Tune, such funding shall be in accordance
                                    with the Tune Budget (such funding, the
                                    "Pre-Closing Capital Contribution"). It is
                                    agreed that such Pre-Closing Capital
                                    Contributions shall include MTVN's and
                                    Tune's overhead allocations on the following
                                    basis: For MTVN, overhead shall be charged
                                    and allocated in the same manner as it will
                                    be charged and allocated to Music.co after
                                    the Closing. For Tune, overhead shall be
                                    charged and allocated in the same manner as
                                    historically charged and allocated to Box
                                    and SonicNet and as reflected in the Tune
                                    Budget. Each of MTVN and Tune shall provide
                                    the other with periodic reports regarding
                                    the level of capital contributions to its
                                    businesses. At the Closing, MTVN and Tune
                                    will disclose their respective Pre-Closing
                                    Capital Contributions and if either party's
                                    Pre-Closing Capital Contribution is less
                                    than its pro-rata share (based on the
                                    party's interest in the equity of Music.co)
                                    of the parties' combined Pre-Closing Capital
                                    Contribution, such party shall contribute to

                                    obligations in respect of such assets and

                                    reimburse Music.co retroactively to the time
                                    such related party transaction was
                                    implemented for the full cost of the benefit
                                    of such transaction as determined by the
                                    auditor ("Auditor's Findings") and MTVN
                                    shall be required to pay for such audit;
                                    otherwise, Tune shall be required to pay for
                                    such audit. If either party disagrees with
                                    the Auditor's Findings, such party (the
                                    "Notifying Party") shall deliver a written
                                    notice thereof ("the Dispute Notice") to the
                                    other party (the "Receiving Party") within
                                    30 days after receipt of the Auditor's
                                    Findings. If no Dispute Notice is received
                                    by the Receiving Party within such 30-day
                                    period, the Auditor's Findings shall be
                                    final and binding on MTVN and Tune. Upon
                                    receipt by the Receiving Party of the
                                    Dispute Notice, MTVN and Tune shall
                                    negotiate in good faith to resolve any
                                    disagreement with respect to the Auditor's
                                    Findings. If MTVN and Tune are unable to
                                    agree with respect to the Auditor's Findings
                                    within 30 days after receipt by the
                                    Receiving Party of the Dispute Notice, MTVN
                                    and Tune shall promptly submit their dispute
                                    to an arbitrator with no material
                                    relationship to MTVN or Tune, selected by
                                    the Notifying Party and reasonably
                                    satisfactory to the Receiving Party, for a
                                    binding resolution. The cost of the
                                    arbitration will be borne as determined by
                                    the arbitrator.


                                    Prior to the IPO, in the event that MTVN or
                                    any Controlled Affiliate of MTVN engages in
                                    a related party transaction not contemplated
                                    by the Related Party Agreements which
                                    involves amounts (in any one transaction or
                                    in a series of related transactions) in
                                    excess of $1,000,000, MTVN must present such
                                    transactions to Tune. It is agreed that the
                                    issuance of equity by or options to purchase
                                    equity in Music.co to employees of MTVN or
                                    Viacom Inc. shall not constitute a related
                                    party transaction unless such equity is
                                    issued to such employee in lieu of regular
                                    compensation and; provided, that such
                                    issuances in the aggregate shall not exceed
                                    10% of the outstanding equity of Music.co.
                                    Tune may approve such transactions; however,
                                    if Tune declines to

                                    approve such transaction, Tune may designate
                                    an independent third party appraiser (the
                                    "Appraiser"), who shall be reasonably
                                    acceptable to MTVN, to determine the
                                    fairness of the financial terms of such
                                    transaction. If the Appraiser determines
                                    (the "Appraiser's Findings") that the
                                    transaction(s) is unfair to Music.co by an
                                    amount equal to 10% or more of the aggregate
                                    net present value (using a 10% discount
                                    rate) of the financial terms of such
                                    transaction(s), MTVN shall elect either not
                                    to engage in the transaction(s) or to modify
                                    the financial terms in order to put such
                                    transaction on an arm"s length basis for
                                    future periods and to reimburse Music.co
                                    retroactively to the time such related party
                                    transaction was implemented for the full
                                    cost of the benefit of such transaction as
                                    determined by the Appraiser. Otherwise, MTVN
                                    and Music.co may engage in the transaction
                                    as originally presented to Tune. The cost of
                                    such appraisal shall be borne by Tune unless
                                    MTVN determines not to enter into the
                                    transaction or such transaction requires an
                                    adjustment as specified above, in which case
                                    such costs shall be borne by MTVN. If either
                                    party disagrees with the Appraiser's
                                    Findings, such party (the "Appraiser
                                    Notifying Party") shall deliver a written
                                    notice thereof ("Appraiser Dispute Notice")
                                    to the other party (the "Appraiser Receiving
                                    Party") within 30 days after receipt of the
                                    Appraiser's Findings. If no Appraiser
                                    Dispute Notice is received by the Appraiser
                                    Receiving Party within such 30-day period,
                                    the Appraiser's Findings shall be final and
                                    binding on MTVN and Tune. Upon receipt by
                                    the Appraiser Receiving Party of the
                                    Appraiser Dispute Notice, MTVN and Tune
                                    shall negotiate in good faith to resolve any
                                    disagreement with respect to the Appraiser's
                                    Findings. If MTVN and Tune are unable to
                                    agree with respect to the Appraiser's
                                    Findings within 30 days after receipt by the
                                    Appraiser Receiving Party of the Appraiser
                                    Dispute Notice, MTVN and Tune shall promptly
                                    submit their dispute to an arbitrator with
                                    no material relationship to MTVN or Tune
                                    selected by the Appraiser Notifying Party
                                    and reasonably satisfactory to the Appraiser
                                    Receiving Party for a binding resolution.
                                    The cost of the arbitration will be borne as
                                    determined by the arbitrator.

OFFICERS:                           Music.co shall have a Chief Executive
                                    Officer. The Chief Executive Officer (and,
                                    for so long as the Minimum Percentage
                                    Condition is met, any successor) shall be
                                    nominated by MTVN, subject to consultation
                                    with Tune. The Chief Executive Officer may
                                    be removed with or without cause (subject to
                                    the obligations of any employment agreement
                                    with such officer) by a vote of the majority
                                    of the Management Committee.

CAPITAL CONTRIBUTIONS:              The Management Committee of Music.co may
                                    request that MTVN and Tune make additional
                                    contributions to Music.co from time to time
                                    prior to the IPO (each an "Additional
                                    Contribution" which term shall be deemed to
                                    include the Closing Contributions and the
                                    Pre-Closing Capital Contributions) in order
                                    to fund its operations in accordance with
                                    the approved budget. Such Additional
                                    Contributions shall be made by MTVN and Tune
                                    on a pro-rata basis (based on their
                                    percentage Interests) as required by and in
                                    accordance with then current budgets up to
                                    an aggregate amount of (x) $90 million in
                                    the case of MTVN, and (y) $10 million in the
                                    case of Tune, in each case taking into
                                    account the Closing Contribution and
                                    Pre-Closing Capital Contributions.


                                    Without limiting MTVN's rights and remedies
                                    in the event Tune fails to make a required
                                    Additional Contribution, in the event Tune
                                    fails to make an Additional Contribution,
                                    MTVN or any third party may contribute the
                                    Tune amount as equity, in which case Tune's
                                    percentage interest in Music.co shall be
                                    diluted to the percentage that the aggregate
                                    amount of capital contributions made by Tune
                                    bears to the aggregate amount of all capital
                                    contributions to Music.co by its partners
                                    assuming an initial valuation of the Tune
                                    Contribution (excluding any Additional
                                    Contribution) equal to $*; provided,

                                    would result in Tune's percentage interest
                                    in Music.co being diluted to less than 5%
                                    (or such proportionate lower percentage as
                                    appropriate if Tune has sold any equity in
                                    Music.co.), shall be made as unsecured debt
                                    (on market terms), rather than as equity.

PUBLIC OFFERING:                    The parties acknowledge their intention that

                                    and listed on The Nasdaq Stock Market or a
                                    national securities exchange. For the
                                    avoidance of doubt, the failure of such IPO
                                    to occur prior to such date shall not be a
                                    breach.


                                    In conjunction with the IPO, the parties
                                    shall take such steps as may be reasonably
                                    necessary to cause Music.co to be rolled up
                                    into a Delaware corporation immediately
                                    prior to the IPO. The certificate of

                                    shall incorporate the management and

                                    Upon receipt by MTVN of the Tune Notice,

                                    agree on the fair market value of the Tune
                                    Partner's Shares or Interests. If the

                                    60 days after the Tune Notice was received
                                    by MTVN, each of MTVN and Tune shall retain
                                    within 30 days thereafter an investment bank
                                    to determine the fair market value of the

                                    bank which shall be unaffiliated with any of
                                    the first two investment banks and shall not

                                    investment bank shall select one of the two
                                    determinations which it believes is the fair
                                    market value of such Shares or Interests
                                    within thirty (30) days from the date of its
                                    selection. The determination of the fair
                                    market value in accordance with the
                                    foregoing procedure shall be final and
                                    binding on the parties and shall be the
                                    "Private Share Valuation". The determination
                                    of the Private Share Valuation of the Tune
                                    Partner's Shares or Interests shall be based
                                    on a valuation of Music.co on the greater of
                                    a going concern or liquidation basis. In
                                    addition, such valuation shall assume the
                                    continuation of the Promotion Agreement in
                                    accordance with its then current terms.

                                    shall offer the Tune Partners an opportunity

                                    in Music.co on the same basis as the MTVN
                                    Partners (taking into account their relative
                                    equity interests in Music.co) instead of
                                    being cashed out in such transaction.

                                    exceptions with the primary purpose of

                                    competition provisions pursuant to which
                                    such acquisition is permitted, at such time

                                    Music.co at a price not in excess of the
                                    fair market value of the consideration paid
                                    and if Music.co declines to purchase such
                                    competing business, Liberty or Tune must, or
                                    must cause the Controlled Affiliate to,
                                    divest it, unless (i) the Board of Directors
                                    of Liberty or Tune or such Controlled
                                    Affiliate shall have been advised by outside
                                    counsel that the approval by such Board of
                                    such sale to Music.co or divestiture (a
                                    "Disposition") is reasonably likely to
                                    constitute a breach by such directors of
                                    their fiduciary duties owed to third parties
                                    or stockholders other than stockholders of
                                    Tune or its parent entities, (ii) such
                                    Disposition would violate the provisions of
                                    any contract to which Liberty, Tune or such
                                    Controlled Affiliate is a party (other than
                                    contracts entered into with a primary
                                    purpose referred to in the last sentence of
                                    the preceding paragraph), or (iii) such
                                    Disposition would trigger any tax liability
                                    for Liberty or Tune or such Controlled
                                    Affiliate which is material to Liberty or
                                    Tune and would otherwise not be triggered;
                                    provided, however, that in the event of the
                                    occurrence of any of the circumstances
                                    referred to in clauses (i)-(iii) above, such
                                    obligation to make a Disposition shall arise
                                    at such subsequent time during the
                                    restricted period applicable thereto, if
                                    any, as such potential breach of fiduciary
                                    duty or potential breach of contract or such
                                    adverse tax consequence may be reasonably
                                    avoided.

                                    Imagine Radio so long as its performance
                                    hereunder is guaranteed by MTVN in
                                    accordance with Section 5 of the Letter
                                    Agreement), in each case so long as any such
                                    member of a Stockholder Group remains a
                                    wholly-owned direct or indirect subsidiary
                                    of Tune, Liberty or Viacom Inc., as

                                    A direct or indirect pledge of an Interest
                                    in Music.co to secure indebtedness for money

                                    transaction shall not constitute a transfer
                                    of an Interest prior to foreclosure on such
                                    pledge, so long as there is no voting proxy

                                    After the Restricted Period, MTVN will have
                                    a right of first offer on customary terms
                                    with respect to any transfer of Tune's
                                    Shares (other than transfers permitted
                                    pursuant to this section during the
                                    Restricted Period), except with respect to
                                    Tune Shares offered to the public pursuant
                                    to Tune's Registration Rights referred to
                                    below; provided that in determining whether
                                    MTVN's offer is higher than a third party
                                    offer pursuant to this right of first offer,
                                    such offers shall be evaluated on an after
                                    tax basis.


                                    After the end of the Restricted Period until
                                    the sixth anniversary of the Closing, if
                                    MTVN intends to sell a controlling interest
                                    in Music.co in one transaction or a series
                                    of related transactions, (i) MTVN will have
                                    pro-rata drag-along rights vis-a-vis Tune
                                    and (ii) Tune will have pro-rata tag-along
                                    rights vis-a-vis MTVN; provided, however,
                                    that such drag-along rights will not be
                                    available to MTVN in a sale of less than all
                                    of its interest in Music.co if it structures
                                    a transaction in such a manner that as a
                                    result of an agreement or arrangement with
                                    the acquiring entity MTVN will end up with a

                                    or through the acquisition of an interest in
                                    the acquiring entities) within a 12 month
                                    period after such sale and provided that if
                                    MTVN sells a controlling interest in
                                    Music.co in a series of related
                                    transactions, Tune's tag along and drag
                                    along shall be at the related weighted

PREEMPTIVE RIGHTS:

                                    Prior to the IPO and for so long as the
                                    Minimum Percentage Condition is satisfied,
                                    Tune will have the right to participate, on
                                    a pro-rata basis, in connection with any
                                    issuance of additional Interests or Shares,
                                    (i) other than with respect to the sale of
                                    Interests or Shares to directors, employees
                                    or consultants of Music.co, MTVN or Viacom
                                    International Inc. pursuant to an employee,
                                    consultant or director option plan or (ii)
                                    in a public offering. Following the IPO and
                                    for so long as Tune satisfies the Minimum
                                    Percentage Condition, Tune will be entitled
                                    to participate on a pro-rata basis with MTVN
                                    in connection with any offering of Shares to
                                    MTVN.

CONFIDENTIALITY:                    Except as and to the extent required by law,
                                    each party will keep confidential any
                                    information obtained from the other party in
                                    connection with the transactions
                                    contemplated by this Term Sheet. If
                                    negotiations of the agreements contemplated
                                    by this Term Sheet are terminated, each
                                    party will return to the other applicable
                                    party all information obtained by such party
                                    from the other party in connection with the
                                    transactions contemplated by this Term Sheet
                                    and shall destroy all written materials,
                                    memoranda, notes and other writings prepared
                                    which are based upon or otherwise reflect
                                    the information. Any information not
                                    returned or destroyed, including without
                                    limitation, any oral information, shall
                                    remain subject to the confidentiality
                                    obligations.

EXPENSES:                           Except as otherwise set forth herein, each
                                    party will bear its own costs and expenses
                                    arising in connection with the transactions
                                    contemplated hereby.

FREEDOM OF ACTION:

                                    Liberty, Tune, MTVN and Viacom Inc. (and
                                    their respective directors, officers,
                                    employees, shareholders and affiliates) will
                                    not have any obligation to present any
                                    business opportunity to Music.co or to
                                    refrain from engaging in any business other
                                    than as expressly provided in the
                                    Non-Competition or Exclusivity provisions,
                                    as applicable.

REGISTRATION RIGHTS:

                                    (a) Upon the written request by Tune,
                                    Music.co will effect the registration under
                                    the Securities Act of 1933, as amended (the
                                    "Securities Act"), of such amount of Shares

                                                                              24


                                    held by the Tune Stockholder Group as are
                                    specified in such notice; provided, however,
                                    that (i) Music.co shall not be required to
                                    effect any registration pursuant to such
                                    request unless such request covers at least
                                    25% of such Shares, (ii) Tune shall not be
                                    entitled to more than two (2) such completed
                                    registrations (of the full amount of Shares
                                    for which registration is requested), (iii)
                                    Music.co shall not be required to register
                                    Shares if Music.co delivers to Tune an
                                    opinion of counsel to the effect that all
                                    such Shares for which registration was
                                    requested may be sold in a single
                                    transaction without registration under the
                                    Securities Act and (iv) Tune may not
                                    exercise a demand right in order to cause
                                    the IPO. Music.co shall pay all costs and
                                    expenses of such registration, other than
                                    underwriting commissions or direct selling
                                    expenses. Tune may register Shares in the
                                    IPO, subject to underwriter cutbacks, as one
                                    of its piggyback rights (see below);
                                    provided, that the offering of Tune Shares
                                    in the IPO may be cut back to avoid
                                    triggering any tax liabilities for any party
                                    hereto in connection with Music.co's
                                    incorporation.


                                    (b) So long as the Tune Stockholder Group
                                    owns at least 1% of the outstanding Shares
                                    or Interests, Music.co will provide Tune
                                    with at least twenty (20) days written
                                    notice of its plan to proceed with any
                                    registration under the Securities Act (other
                                    than a registration on Form S-4 or Form S-8
                                    or similar or successor forms utilized in
                                    the future), regarding a proposed offering

                                    would also be subject to Tune and Music.co"s
                                    formulation of a mutually acceptable

                                    they may be amended to Tune, Liberty will
                                    not be obligated by the terms of this

innovative and comprehensive presence in music content and commerce on the

with Lee Masters and to expand on the long and close relationship we've had

and SonicNet in to a venture with the MTV Networks' online music business is a
superb way to build significant value for our shareholders. We believe this
enterprise will be the dominant player in the Internet music space. On a
