                          IMCLONE SYSTEMS INCORPORATED

                   5 1/2% CONVERTIBLE SUBORDINATED NOTE DUE 2005

         This Note is one of a duly authorized issue of Notes of the Company,
designated as its 5 1/2% Convertible Subordinated Notes due 2005 (herein called
the "Notes"), limited to the aggregate principal amount of $200,000,000
($240,000,000, if the option is fully exercised by the Initial Purchasers) all
issued or to be issued under and pursuant to an Indenture dated as of February
29, 2000 (herein called the "Indenture"), between the Company and The Bank of
New York, as trustee (herein called the "Trustee"), to which Indenture and all
indentures supplemental thereto reference is hereby made for a description of
the rights, limitations of rights, obligations, duties and immunities thereunder
of the Trustee, the Company and the holders of the Notes.

         In case an Event of Default (as defined in the Indenture) shall have
occurred and be continuing, the principal of, premium, if any, and accrued
interest (including Liquidated Damages (as defined in the Registration Rights
Agreement), if any) on all Notes may be declared by either the Trustee or the
holders of not less than 25% in aggregate principal amount of the Notes then
outstanding, and upon said declaration shall become, due and payable, in the
manner, with the effect and subject to the conditions provided in the Indenture.

         The Indenture contains provisions permitting the Company and the
Trustee, with the consent of the holders of not less than a majority in
aggregate principal amount of the Notes at the time outstanding, to execute
supplemental indentures adding any provisions to or changing in any manner or
eliminating any of the provisions of the Indenture or of any supplemental
indenture or modifying in any manner the rights of the holders of the Notes;
provided, however, that no such supplemental indenture shall (i) extend the
fixed maturity of any Note, or reduce the rate or extend the time of payment of
interest thereon, or reduce the principal amount thereof or premium, if any,
thereon, or reduce any amount payable upon redemption thereof, or impair the
right of any Noteholder to institute suit for the payment thereof, or make the
principal thereof or interest or premium, if any, thereon payable in any coin or
currency other than that provided in the Notes, or modify the provisions of the
Indenture with respect to the subordination of the Notes in a manner adverse to
the Noteholders in any material respect, or change the obligation of the Company
to redeem any Note upon the happening of a Fundamental Change (as defined in the
Indenture) in a manner adverse to the holder of the Notes, or impair the right
to convert the Notes into Common Stock subject to the terms set forth in the
Indenture, including Section 15.6 thereof, without the consent of the holder of
each Note so affected or (ii) reduce the aforesaid percentage of Notes, the
holders of which are required to consent to any such supplemental indenture,
without the consent of the holders of all Notes then outstanding. Subject to the
provisions of the Indenture, the holders of a majority in aggregate principal
amount of the Notes at the time outstanding may on behalf of the holders of all
of the Notes waive any past default or Event of Default under the Indenture and
its consequences except a default in the payment of interest (including
Liquidated Damages, if any) or any premium on, or the principal of, any of the
Notes, or a failure by the Company to convert any Notes into Common Stock of the
Company, or

                                       4
<PAGE>   7
a default in the payment of the redemption price pursuant to Article Three of
the Indenture, or a default in respect of a covenant or provisions of the
Indenture which under Article Eleven of the Indenture cannot be modified without
the consent of the holders of each or all Notes then outstanding or affected
thereby. Any such consent or waiver by the holder of this Note (unless revoked
as provided in the Indenture) shall be conclusive and binding upon such holder
and upon all future holders and owners of this Note and any Notes which may be
issued in exchange or substitution hereof, irrespective of whether or not any
notation thereof is made upon this Note or such other Notes.

         The indebtedness evidenced by the Notes is, to the extent and in the
manner provided in the Indenture, expressly subordinated and subject in right of
payment to the prior payment in full of all Senior Indebtedness of the Company,
whether outstanding at the date of the Indenture or thereafter incurred, and
this Note is issued subject to the provisions of the Indenture with respect to
such subordination. Each holder of this Note, by accepting the same, agrees to
and shall be bound by such provisions and authorizes the Trustee on its behalf
to take such action as may be necessary or appropriate to effectuate the
subordination so provided and appoints the Trustee his attorney-in-fact for such
purpose.

         No reference herein to the Indenture and no provision of this Note or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and any premium and interest
(including Liquidated Damages, if any) on this Note at the place, at the
respective times, at the rate and in the coin or currency herein prescribed.

         Interest on the Notes shall be computed on the basis of a 360-day year
of twelve 30-day months.

         The Notes are issuable in fully registered form, without coupons, in
denominations of $1,000 principal amount and any integral multiple of $1,000. At
the office or agency of the Company referred to on the face hereof, and in the
manner and subject to the limitations provided in the Indenture, without payment
of any service charge but with payment of a sum sufficient to cover any tax,
assessment or other governmental charge that may be imposed in connection with
any registration or exchange of Notes, Notes may be exchanged for a like
aggregate principal amount of Notes of any other authorized denominations.

         The Notes may be provisionally redeemed by the Company, in whole or in
part, at any time prior to March 6, 2003, at a redemption price equal to $1,000
per aggregate principal amount of notes to be redeemed plus accrued and unpaid
interest, if any (including Liquidated Damages Amount, if any) to the date of
redemption if (i) the closing price of the Common Stock shall have exceeded 150%
of the conversion price then in effect for at least 20 trading days in any
consecutive 30-trading day period and (ii) if the redemption would occur before
March 1, 2002, the shelf registration statement covering resales of the Notes
and the Common Stock, issuable upon conversion of the Notes, is effective and
available for use and is expected to remain effective and available for use for
the 30 days immediately following the date of

                                       5
<PAGE>   8

         redemption. The Company shall mail notice of any provisional redemption
within five trading days of a consecutive 30-trading day period.

         Upon any such provisional redemption, the Company shall make an
additional Additional Payment (as defined in the Indenture) with respect to the
Notes called for redemption to holders as of the date of mailing of the notice
of provisional redemption in an amount equal to $152.54 per $1,000 Note, minus
the amount of any interest the Company actually paid on such Note prior to the
Notice Date. The Company shall make the Additional Payment on all Notes called
for provisional redemption, including any Notes converted after the date of
mailing of the notice of provisional redemption and prior to the date of
redemption.

         At any time on or after March 6, 2003, and prior to maturity, the Notes
may be redeemed at the option of the Company, in whole or in part, upon mailing
a notice of such redemption not less than 30 days but not more than 60 days
before the date fixed for redemption to the holders of Notes at their last
registered addresses, all as provided in the Indenture, at the following
optional redemption prices (expressed as percentages of the principal amount),
together in each case with accrued and unpaid interest (including Liquidated
Damages, if any) to, but excluding, the date fixed for redemption:

<S>                                                                       <C>

</TABLE>

and 100% on March 1, 2005; provided, however, that if the date fixed for
redemption is on a March 1 or September 1, then the interest payable on such
date shall be paid to the holder of record on the preceding February 15 or
August 15, respectively.

         The Company may not redeem the Notes if a default in the payment of
interest or premium, if any, on the Notes has occurred and is continuing.

         The Notes are not subject to redemption through the operation of any
sinking fund.

         If a Fundamental Change occurs at any time prior to maturity of the
Notes, the Notes will be redeemable on the 30th day after notice thereof (the
"Repurchase Date") at the option of the holder of the Notes at a redemption
price equal to 100% of the principal amount thereof, together with accrued
interest to (but excluding) the date of redemption; provided, however, that, if
such Repurchase Date is a March 1 or September 1, the interest payable on such
date shall be paid to the holder of record of the Notes on the preceding
February 15 or August 15, respectively. The Notes will be redeemable in
multiples of $1,000 principal amount. The Company shall mail to all holders of
record of the Notes a notice of the occurrence of a Fundamental Change and of
the redemption right arising as a result thereof on or before the 10th day after
the occurrence of such

                                       6
<PAGE>   9
Fundamental Change. For a Note to be so redeemed at the option of the holder,
the Company must receive at the office or agency of the Company maintained for
that purpose in accordance with the terms of the Indenture, such Note with the
form entitled "Option to Elect Repayment Upon a Fundamental Change" on the
reverse thereof duly completed, together with such Note, duly endorsed for
transfer, on or before the 30th day after the date of such notice of a
Fundamental Change (or if such 30th day is not a Business Day, the immediately
succeeding Business Day).

         Subject to the provisions of the Indenture, the holder hereof has the
right, at its option, at any time after the original issuance of any Notes
through the close of business on the final maturity date of the Notes, or, as to
all or any portion hereof called for redemption, prior to the close of business
on the Business Day immediately preceding the date fixed for redemption (unless
the Company shall default in payment due upon redemption thereof), to convert
the principal hereof or any portion of such principal which is $1,000 or an
integral multiple thereof into that number of shares of the Company"s Common
Stock (as such shares shall be constituted at the date of conversion) obtained
by dividing the principal amount of this Note or portion thereof to be converted
by the Conversion Price of $110.18, as may adjusted from time to time as
provided in the Indenture, upon surrender of this Note, together with a
conversion notice as provided in the Indenture (the form entitled "Conversion
Notice" on the reverse hereof), to the Company at the office or agency of the
Company maintained for that purpose in accordance with the terms of the
Indenture, or at the option of such holder, the Corporate Trust Office, and,
unless the shares issuable on conversion are to be issued in the same name as
this Note, duly endorsed by, or accompanied by instruments of transfer in form
satisfactory to the Company duly executed by, the holder or by his duly
authorized attorney. No adjustment in respect of interest on any Note converted
or dividends on any shares issued upon conversion of such Note will be made upon
any conversion except as set forth in the next sentence. If this Note (or
portion hereof) is surrendered for conversion during the period from the close
of business on any record date for the payment of interest to the close of
business on the Business Day preceding the following interest payment date and
either (x) has not been called for redemption on a redemption date that occurs
during such period or (y) is not to be redeemed in connection with a Fundamental
Change on a Repurchase Date that occurs during such period, this Note (or
portion hereof being converted) must be accompanied by an amount, in New York
Clearing House funds or other funds acceptable to the Company, equal to the
interest payable on such interest payment date on the principal amount being
converted; provided, however, that no such payment shall be required if there
shall exist at the time of conversion a default in the payment of interest on
the Notes. No fractional shares will be issued upon any conversion, but an
adjustment and payment in cash will be made, as provided in the Indenture, in
respect of any fraction of a share which would otherwise be issuable upon the
surrender of any Note or Notes for conversion. A Note in respect of which a
holder is exercising its right to require redemption upon a Fundamental Change
may be converted only if such holder withdraws its election to exercise such
right in accordance with the terms of the Indenture. Any Notes called for
redemption, unless surrendered for conversion by the holders thereof on or
before the close of business on the Business Day preceding the date fixed for
redemption, may be deemed to be redeemed from the holders of such Notes for an
amount equal to the applicable redemption price, together with accrued but
unpaid interest

                                       7

(including Liquidated Damages, if any) to (but excluding) the date fixed for
redemption, by one or more investment banks or other purchasers who may agree
with the Company (i) to purchase such Notes from the holders thereof and convert
them into shares of the Company"s Common Stock and (ii) to make payment for such
Notes as aforesaid to the Trustee in trust for the holders.

         Upon due presentment for registration of transfer of this Note at the
office or agency of the Company maintained for that purpose in accordance with
the terms of the Indenture, a new Note or Notes of authorized denominations for
an equal aggregate principal amount will be issued to the transferee in exchange
thereof; subject to the limitations provided in the Indenture, without charge
except for any tax, assessment or other governmental charge imposed in
connection therewith.

         The Company, the Trustee, any authenticating agent, any paying agent,
any conversion agent and any Note registrar may deem and treat the registered
holder hereof as the absolute owner of this Note (whether or not this Note shall
be overdue and notwithstanding any notation of ownership or other writing hereon
made by anyone other than the Company or any Note registrar) for the purpose of
receiving payment hereof, or on account hereof, for the conversion hereof and
for all other purposes, and neither the Company nor the Trustee nor any other
authenticating agent nor any paying agent nor other conversion agent nor any
Note registrar shall be affected by any notice to the contrary. All payments
made to or upon the order of such registered holder shall, to the extent of the
sum or sums paid, satisfy and discharge liability for monies payable on this
Note.

         No recourse for the payment of the principal of or any premium or
interest on this Note, or for any claim based hereon or otherwise in respect
hereof, and no recourse under or upon any obligation, covenant or agreement of
the Company in the Indenture or any supplemental indenture or in any Note, or
because of the creation of any indebtedness represented thereby, shall be had
against any incorporator, stockholder, employee, agent, officer or director or
subsidiary, as such, past, present or future, of the Company or of any successor
corporation, either directly or through the Company or any successor
corporation, whether by virtue of any constitution, statute or rule of law or by
the enforcement of any assessment or penalty or otherwise, all such liability
being, by acceptance hereof and as part of the consideration for the issue
hereof, expressly waived and released.

         This Note shall be deemed to be a contract made under the laws of New
York, and for all purposes shall be construed in accordance with the laws of New
York, without regard to principles of conflicts of laws.

         Terms used in this Note and defined in the Indenture are used herein as
therein defined.

Mischief hereby agrees to transfer, or cause to be transferred, in such
circumstances, to the Company all of the Mischief Partnership Units issued
pursuant to Section 4.1 in exchange for that number and kind of shares of

to the Company in exchange for Company Common Stock on a pro rata basis in
accordance with the previous proviso.

         3.2.     Mischief Share Closing. Unless the parties hereto shall agree

pursuant to this Agreement and the other Operative Agreements to be delivered
by the Company to Shareholder at the Mischief Share Closing.

Alternatively, if MTVNO is entitled to and makes the election in the first
proviso of Section 3.1, then Mischief shall deliver, or cause to be delivered,
to the Company all of the Mischief Partnership Units, and the Company shall
accept and acquire such Mischief Partnership Units from Mischief, and deliver in
exchange therefor the amount of Company Common Stock required by Section 3.1
above. Mischief shall take all action necessary for the Company to be admitted

date of this Agreement and on and as of the Mischief Share Closing Date, except
for representations and warranties that speak as of a specific date or time
(which need only be true and correct in all material respects as of such date or
time); provided, however, that the failure of any such representation or
warranty to be so true and correct shall not provide a basis for MTVNO not to
consummate the Mischief Share Closing so long as (i) the Losses known by MTVNO
to be indemnifiable by Shareholder as of the date of the closing of the IPO do
not exceed the value (as determined in accordance with the provisions of Section
10.6 hereof) of the Pledged Shares immediately prior to the consummation of the

         (b)      MTVNO shall have performed and complied in all material
respects with all covenants and agreements required by this Agreement to be

                                    ARTICLE 7

                     REPRESENTATIONS AND WARRANTIES OF MTVNO

         MTVNO hereby represents and warrants to Mischief and Shareholder, as
follows:

         7.1.     Formation; Existence. MTVNO is a partnership, validly existing
under the laws of the State of Delaware, and has the requisite partnership power
and authority to own, lease and operate its assets and businesses as currently
being conducted, except in any such case as would not have a material adverse
effect on its ability to perform its obligations hereunder.

         7.2.     Due Authority; Valid, Binding and Enforceable.

         (a)      MTVNO has the requisite partnership power and authority to
enter into and perform this Agreement and the other Operative Agreements to
which it is a party; the execution, delivery and performance by it of this
Agreement and of the other Operative Agreements to which it is a party have been
duly authorized by all required partnership action on its part and, if required,
by its partners, and this Agreement and the other Operative Agreements to which
it is a party have been duly executed and delivered by it.

         (b)      This Agreement and the other Operative Agreements to which it
is a party are legal, valid and binding obligations of MTVNO, enforceable
against it in accordance with their respective terms, except as such
enforceability may be limited by bankruptcy, insolvency, fraudulent conveyance,
reorganization or other similar laws affecting the enforcement of creditors'
rights generally and except to the extent that injunctive or other equitable
relief is within the discretion of a court of competent jurisdiction.

         7.3.     No Violation of Laws or Agreements. Except for the notice and
preemptive rights under the Partnership Agreement, the execution, delivery, and
performance by MTVNO of this Agreement and the other Operative Agreements to
which it is a party and the consummation by it of the transactions contemplated
hereby and thereby with respect to MTVNO do not and will not, (a) violate,
conflict with or result in the breach of any provision of its certificate of
limited partnership or the Partnership Agreement, or (b) violate, conflict with,
result

<PAGE>   25
                                                                              20

in a breach of, or constitute a default (or an event which would, with the
passage of time or the giving of notice or both, constitute a default) under,
require any consent under, or notice to, or filings with or result in or permit
the termination, amendment, modification, acceleration, suspension, revocation
or cancellation of, or result in the creation or imposition of any Lien of any
nature whatsoever upon any of its assets, or give to others any interests or
rights therein under (i) any license, plan, Permit or Contract to which it is a
party or (ii) any judgment, injunction, writ, award, decree, restriction,
ruling, or order of any court, arbitrator or Governmental Entity or any
applicable constitution, or Law, to which it is subject with such exceptions as,
individually and in the aggregate, would not have a material adverse effect on
its ability to perform its obligations under this Agreement and the other
Operative Agreements to which it is a party. Except for the notice and
preemptive rights under the Partnership Agreement, no filing, consent, waiver,
approval or authorization of any Governmental Entity or of any third party on
the part of MTVNO is required in connection with the execution, delivery and
performance of this Agreement and the other Operative Agreements to which it is
a party or the consummation of the transactions contemplated hereby or thereby.

         7.4.     Issuance of Partnership Units and Company Common Stock. The
issued and outstanding Partnership Units immediately following the execution,
delivery and performance of this Agreement and the other Operative Agreements
are as indicated in Amendment No. 2. The Mischief Partnership Units are free and
clear of all Liens (other than those contemplated by the Operative Agreements)
and have been duly authorized and validly issued and have not been issued in
violation of any preemptive rights or, assuming the representations and
warranties of Shareholder in this Agreement are true and correct, securities
laws. The Company Common Stock will be, when issued at the Mischief Share
Closing, duly authorized, free and clear of all Liens (other than those
contemplated by the Operative Agreements) and will be validly issued, fully paid
and non-assessable, and will not have been issued in violation of any preemptive
rights or, assuming the representations and warranties of Shareholder in this
Agreement are true and correct, securities laws. The Company will be, as of the
date of the consummation of the IPO, a corporation duly incorporated, validly
existing and in good standing as a corporation under the laws of the State of
Delaware and the issuance by the Company of Company Common Stock will not (a)
violate, conflict with or result in the breach of any provision of the
certificate of incorporation or by-laws of the Company, or (b) violate, conflict
with, result in a breach of, or constitute a default (or an event which would,
with the passage of time or the giving of notice or both, constitute a default)
under, require any consent under, or notice to, or filings with or result in or
permit the termination, amendment, modification, acceleration, suspension,
revocation or cancellation of, or result in the creation or imposition of any
Lien of any nature whatsoever upon any of the businesses or assets of the
Company or give to others any interests or rights therein under any Contract of
the Company, except in any case under this clause (b) as would not, individually
or in the aggregate, have a material adverse effect on the businesses or assets
of the Company.

         7.5.     Securities Act Matters. Subject to the terms and conditions of
this Agreement, at the Mischief Share Closing, the Company will acquire the
Mischief Shares under this Agreement for its own account and not with a view to
any distribution thereof in violation of the Securities Act. The Company
acknowledges and agrees that the Mischief Shares acquired pursuant to this
Agreement have not been and will not be registered under the Securities Act (or

<PAGE>   26
                                                                              21

any state or foreign securities Laws) and may not be reoffered, sold, assigned,
transferred, pledged, encumbered, or otherwise disposed of in the absence of
such registration or an available exemption from such registration requirements.

                                    ARTICLE 8

                                    COVENANTS

         8.1.     Partnership Agreement. Simultaneously herewith, Mischief,
Shareholder, MTVNO, VLLC, Imagine MTVN Online, SonicNet and Box have executed
and delivered, each to the other, Amendment No. 2, amending the Partnership
Agreement.

         8.2.     Employment Agreement.  Simultaneously herewith, Shareholder
and MTVNO have executed and delivered, each to the other, the Employment
Agreement.

         8.3.     Pledge Agreement.  Simultaneously herewith, Shareholder and
Mischief have executed and delivered to MTVNO the Pledge Agreement.

         8.4.     Conduct of Mischief Business Prior to Mischief Share Closing.
Except as contemplated in this Agreement, from the date hereof to the Mischief
Share Closing Date, Mischief and Shareholder, as the case may be, will not (i)
carry on any business or operations of any kind whatsoever through Mischief,
except for ministerial actions required to maintain Mischief's corporate
existence and the collection of any Receivables, (ii) amend any of Mischief's
organizational documents, (iii) declare or pay any dividends on or make other
distributions in respect of any of Mischief's capital stock other than cash
dividends, (iv) redeem, repurchase or otherwise acquire, or split, combine or
reclassify, any Mischief Shares, (v) issue, agree to issue, deliver, sell,
award, pledge, dispose of or otherwise encumber or authorize or propose the
issuance, delivery, sale, award, pledge, disposition or other encumbrance of,
any shares of Mischief's capital stock of any class or any securities
convertible into or exchangeable for, or any rights, warrants or options to
acquire, any such shares or convertible or exchangeable securities, (vi) create,
incur or assume any indebtedness for borrowed money, whether or not in the
ordinary course of business, (vii) change any method of accounting or accounting
practice except as required by GAAP as in effect from time to time or (viii)
make any material tax election (other than an S-corporation election and a
change in its fiscal year to December 31) or change in tax accounting of
Mischief. For the avoidance of doubt, from the date hereof, Shareholder agrees
not to sell, exchange, assign, transfer, pledge, hypothecate or otherwise
dispose of any of the Mischief Shares, except to MTVNO. In addition, Shareholder
agrees that immediately prior to the consummation of the Mischief Share Closing
he will cause to be satisfied, and he will assume, all obligations and
liabilities of Mischief.

         8.5.     Non-Competition. (a) For purposes of this Agreement,
"Non-Compete Parties" means any and all of MTVNO, any subsidiary of MTVNO or
other Affiliate of MTVNO controlled by Viacom, the Company or any of its or
their successors or assigns. Each of Mischief and Shareholder agree that it or
he, as the case may be, shall not, prior to the third anniversary of the date
hereof (the "Non-Compete Period"), directly or indirectly, individually or for,
with or through any other Person (which shall be deemed to include any equity
participation

<PAGE>   27
                                                                              22

in any other Person), (i) acquire or own in any manner any interest or
investment in (whether as a security holder, creditor or otherwise) any Person
that directly or indirectly owns, operates, manages or distributes a business
that directly competes with the Business (a "Competing Business"), (ii)
participate in, advertise or promote in any manner any Competing Business, or
(iii) be employed by or serve as an employee, manager, agent, officer or
director of, or consultant to, any Person that engages, directly or indirectly,
in a Competing Business, in each case, in any state or other jurisdiction
worldwide in which any Non-Compete Party is engaged in such business; provided,
however, that nothing herein shall be construed to prevent Shareholder from
owning, as an investment, up to 1% of a class of equity securities issued by any
competitor of any Non-Compete Party that is publicly traded and registered under
Section 12 of the Securities and Exchange Act of 1934, as amended; provided,
further, that the provisions of this non-competition agreement shall not apply
to Mischief on and after the Mischief Share Closing Date. The parties intend
that the covenant contained in the preceding sentence shall be construed as a
series of separate covenants, one for each county and city included within each
state or other jurisdiction and, except for geographic coverage, each such
separate covenant shall be deemed identical. The parties agree that the
covenants deemed included in this Section are, taken as a whole, reasonable in
their geographic scope and their duration and no party shall raise any issue of
the reasonableness of the scope or duration of the covenants in any proceeding
to enforce any such covenants. If, in any judicial proceeding, a court shall
refuse to enforce any separate covenant, then the unenforceable covenant shall
be modified in order to make it acceptable to the court and enforced
accordingly, or, if necessary, deemed eliminated to the extent necessary to
permit the remaining separate covenants to be enforced.

         (b)      For a period of three years after the date hereof, Shareholder
agrees that he shall not, directly or indirectly, for himself or for any other
Person, attempt to employ or enter into any employment, consulting or similar
relationship or arrangement, directly or indirectly, with any employee or former
employee of Mischief or the Non-Compete Parties, unless such employee or former
employee has not been employed by Mischief or the Non-Compete Parties, as the
case may be, for a period of more than six months.

         (c)      It is acknowledged and agreed by the parties hereto that a
breach by Mischief or Shareholder of any of the covenants contained in this
Section 8.5 will cause irreparable harm and damage to the Non-Compete Parties,
the monetary amount of which may be virtually impossible to ascertain. As a
result, Mischief and Shareholder hereby acknowledge and agree that the
Non-Compete Parties shall be entitled to an injunction from any court of
competent jurisdiction enjoining and restraining any violation of any or all of
the covenants contained in this Section 8.5 by Mischief or Shareholder or any of
its or their Affiliates, either directly or indirectly, and that such right to
injunction shall be cumulative and in addition to whatever other remedies the
Non-Compete Parties may possess.

         8.6. Shareholder's Put Right.

         (a)      In the event that an IPO fails to close by the second
anniversary of the date hereof, at any time during the 60-day period commencing
on such anniversary, Shareholder and Mischief may, by irrevocable written notice
from Shareholder to MTVNO (the "Put Notice"), require MTVNO or an entity
designated by MTVNO to purchase, subject to the provisions of

<PAGE>   28
                                                                              23

Section 8.6(b)(iii) below, all, but not less than all, of both (i) the
Partnership Units owned by Shareholder and any Permitted Transferees of
Shareholder and Mischief and (ii) the Mischief Shares. Any such purchase shall
be effected, for cash, on the date which is the earlier of (x) the 90th day
following the second anniversary of the date hereof, or (y) the 30th day
following MTVNO's receipt of the Put Notice (or, in either case, if not a
Business Day the next following Business Day) (the "Put Closing Date"), and at a
total price for all such Partnership Units and Mischief Shares equal to
$4,700,000 (the "Put Purchase Price"). Mischief and Shareholder shall cause
their respective Permitted Transferees to participate in any such purchase or
sale for no additional consideration. The Put Purchase Price will be allocated
proportionately (in relationship to Partnership Units beneficially owned) among
all of Mischief, Shareholder and any of their Permitted Transferees selling
their Partnership Units and Mischief Shares to MTVNO or its designee upon
exercise of the Put.

         (b)      If a Put Notice is delivered, then MTVNO and/or its designee
and Mischief, Shareholder and any of their Permitted Transferees shall proceed
with the closing of the purchase (the "Put Closing") as follows:

                  (i)      The Put Closing shall be held at the principal office
of MTVNO on the Put Closing Date, or at such other place or on such other date
as MTVNO shall designate that is a reasonably convenient location to avoid stamp
duty or other transfer taxes to the extent that it is not unlawful to do so.

                  (ii)     At the Put Closing, MTVNO shall purchase (or cause
its designee to purchase) all but not less than all of both the applicable
Partnership Units and the Mischief Shares for the Put Purchase Price, and
against payment of such price in cash, Mischief, Shareholder and each of their
Permitted Transferees, as the case may be, shall deliver all such documents and
instruments as are reasonably necessary to transfer, and shall represent and
warrant to MTVNO that it has transferred, good and marketable title to the
applicable Partnership Units and the Mischief Shares being sold to MTVNO or its
designee, free and clear of all Liens, other than those created by this
Agreement or created by MTVNO.

                  (iii)    The obligation of MTVNO or its designee to proceed
with the Put Closing shall be subject to the satisfaction of the terms and
conditions (with reference to the Mischief Shares portion of the Put Closing) of
Sections 3.3 and 3.4 relating to a transfer of Mischief Shares (substituting the
Put Closing and the Put Closing Date for the references to the Mischief Share
Closing and the Mischief Share Closing Date, respectively); provided, however,
that in the event that (i) the conditions specified in Section 3.4 hereof are
not satisfied on the Put Closing Date and (ii) the Losses known by MTVNO to be
indemnifiable by Shareholder as of the Put Closing Date exceed the value (as
determined in accordance with the provisions of Section 10.6 hereof) of the
Pledged Shares immediately prior to the consummation of the Put Closing, MTVNO
may, in its sole discretion, elect to require that Mischief instead transfer, or
cause to be transferred, and Mischief hereby agrees to transfer, or cause to be
transferred, in such circumstances, to the Company all of the Mischief
Partnership Units issued pursuant to Section 4.1 in exchange for that number and
kind of shares of Company Common Stock which Shareholder would otherwise have
been entitled to receive for his Mischief Shares. The obligation of MTVNO or its
designee to proceed with the Put Closing shall also be conditioned

<PAGE>   29
                                                                              24

upon, and the scheduled Put Closing Date, shall be extended to 10 days following
the last to occur of, the receipt of all material governmental and regulatory
consents, approvals or waivers that may be required in connection with the
purchase and sale of the applicable Partnership Units and the Mischief Shares
(other than any such consent or approval which has, if permitted by law, been
waived by MTVNO or its designee).

                                    ARTICLE 9

                               REGISTRATION RIGHTS

         9.1.     Demand Rights.

         (a)      From and after the first anniversary of the consummation of
the IPO, Shareholder and his Permitted Transferees (each, a "Mischief
Stockholder"), and collectively, the "Mischief Stockholder Group," shall have
the right, upon written notice from Shareholder to the Company and subject to
the provisions of this Article 9, to require the Company to prepare and file as
soon as practicable after receipt of such notice and use its reasonable best
efforts to cause to become effective as soon as practicable thereafter a
registration statement (a "Registration Statement") under the Securities Act of
1933, as amended (the "Securities Act" ), with respect to the resale of all
Registrable Shares requested by the Mischief Stockholder Group to be so
registered (a "Demand Registration"); provided, however, that the Company shall
not be required to violate the terms of any "lock-up" or "standstill" provisions
relating to any securities offering by it by which it may be bound by an
underwriter; provided, further, that if the Company determines, in its
reasonable good faith business judgment, that the filing of such Registration
Statement and the offering of Registrable Shares covered thereby would interfere
with or otherwise adversely affect any financing, acquisition, corporate
reorganization or other material transaction or development involving the
Company or any of its Affiliates or require the Company to disclose material
matters regarding itself or such Affiliates that otherwise would not be required
to be disclosed at such time, then the Company may delay the filing of such
Registration Statement for a period of up to sixty days.

         (b)      Notwithstanding anything to the contrary contained herein, the
Company shall have no obligation to prepare, file and cause to become effective
the Registration Statement if the Company delivers to Shareholder an opinion of
counsel (which counsel may be an employee of MTVNO or its Affiliates) to the
effect that all such Registrable Shares for which registration was requested may
be publicly sold in a single transaction without registration under the
Securities Act pursuant to Rule 144 thereunder. Furthermore, the Company shall
not be obligated to prepare, file and cause to become effective Registration
Statements for more than one such registration pursuant to this Section 9.1.

         (c)      If the selling Mischief Stockholder Group so elects, it may
cause the public offering or distribution of the Registrable Shares pursuant to
the Demand Registration to be pursuant to a firm commitment underwriting, the
managing underwriter of which shall be a nationally recognized investment
banking firm selected by the Company and approved by Shareholder, such approval
not to be unreasonably withheld. The Company shall enter into the same
underwriting agreement as shall the selling Mischief Stockholder Group,
containing

<PAGE>   30
                                                                              25

representations, warranties, indemnities, and agreements acceptable to the
Company and not substantially different from those customarily made by an issuer
in underwriting agreements with respect to secondary distributions. If (i) the
Demand Registration is for a firm commitment underwritten public offering and
the managing underwriter thereof determines in good faith that the aggregate
number of Registrable Shares to be offered thereby exceeds the total number of
Registrable Shares that may be successfully offered at an estimated initial
price per share to the public that is at least equal to the minimum initial
price per Registrable Share (which shall not be higher than the market price at
the time of designation) to the public that has been designated in writing at
the time of the notice referred to in Section 9.1(a) by the Shareholder, and/or
(ii) the Demand Registration is delayed more than 30 days pursuant to Section
9.3(b) of this Agreement prior to being declared effective, and in either case
no Registrable Shares are sold pursuant to such Demand Registration, then the
selling Mischief Stockholder Group shall withdraw its request for such
registration by giving written notice to the Company to such effect, in which
event, such registration shall not be deemed to have occurred for purposes of
the last sentence of Section 9.1(b).

         (d)      The selling Mischief Stockholder Group may elect to withdraw
their Registrable Shares from inclusion in a Demand Registration; provided that,
except for a withdrawal pursuant to the last sentence of Section 9.1(c),
notwithstanding such withdrawal, such registration shall be deemed to have
occurred for the purposes of the last sentence of Section 9.1(b).

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

         (f)      The Company shall have the right, and may grant to any other
Person the right, to include any other Registrable Shares in any Registration
Statement filed pursuant to this Section 9.1.

         9.2.     Piggy-Back Rights.

         (a)      From and after the six (6) month anniversary of the
consummation of the IPO until the third anniversary of the consummation of the
IPO, each time that the Company intends to proceed with the actual preparation
and filing of a registration statement under the Securities Act for its own
account in connection with the proposed offer and sale for money of any
securities of the Company (other than a registration statement on Form S-4 or
Form S-8 or any successor to either such form), the Company will give at least
20 days written notice of its election to Shareholder. Upon the written request
of Shareholder to the Company given within 10 days after receipt of any such
notice from the Company, the Company will, except as herein provided, use its
reasonable efforts to cause all Registrable Shares for which Shareholder has
requested registration to be included in such registration statement, all to the
extent requisite to permit the sale or other disposition by the Mischief
Stockholder Group of the Registrable Shares

<PAGE>   31
                                                                              26

to be so registered; provided, however, that (i) nothing herein shall prevent
the Company from, at any time, abandoning or delaying any such registration
initiated by it and thereupon the Company shall have no obligation to complete a
registration for the benefit of the Mischief Stockholder Group; (ii) for
purposes of this sentence, the use by the Company of reasonable efforts shall
not require the Company to reduce the amount or sale price of the securities it
proposes to distribute for its own account; (iii) the Company shall not be
required to violate the terms of any "lock-up" or "standstill" provisions
relating to any securities offering by which it may be bound; (iv) the number of
requests for registration pursuant to this Section 9.2(a) by Shareholder shall
not exceed two; (v) the rights granted under this Section 9.2 shall be equal in
priority to the rights of any other Person now having, or hereafter granted,
similar piggy-back rights with respect to Company Common Stock; and (vi) the
provisions of Section 9.1(b) shall apply equally with respect to the obligation
of MTVNO under this Section 9.2(a). If any registration pursuant to this Section
9.2 shall be underwritten in whole or in part, (A) the Company may require that
the Registrable Shares requested for inclusion pursuant to this Section 9.2 be
included in the underwriting on the same terms and conditions as the Registrable
Shares otherwise being sold through the underwriters and (B) the selling
Mischief Stockholder Group may elect through Shareholder, in writing not less
than fifteen Business Days prior to the effective date of the registration
statement filed in connection with such registration, not to register their
Registrable Shares in connection with such registration. No registration
effected under this Section 9.2 shall relieve the Company of its obligation to
effect the Demand Registration in accordance with Section 9.1.

         (b)      In connection with a registration under this Section 9.2, the
Company may enter into an underwriting agreement in such customary form as shall
have been negotiated and agreed to by the Company with the underwriter or
underwriters selected for such underwriting by the Company. Notwithstanding any
other provision of this Section 9.2, if in the opinion of the managing
underwriter the inclusion of Registrable Shares owned by the Mischief
Stockholder Group in a registration statement would reduce the amount or sale
price of the other securities to be included in such registration, the Company
may reduce (pro rata with other selling shareholders), to as low as zero, the
number of Registrable Shares to be included by the Mischief Stockholder Group in
the registration and underwriting under this Section 9.2, to the extent
necessary to cause inclusion of such Registrable Shares not to be detrimental to
the registration filed pursuant to this Section 9.2.

         9.3.     General Registration Provisions.

         (a)      If and whenever the Company is required by the provisions of
this Article 9 to effect the registration of Registrable Shares owned by the
Mischief Stockholder Group under the Securities Act, the Company will:

                  (i)      subject to the terms and conditions of this Article
9, prepare and file with the SEC a registration statement with respect to such
Registrable Shares, and use its reasonable best efforts to cause such
registration statement to become and remain effective for such period as may be
reasonably necessary to effect the sale of such Registrable Shares, but in no
event longer than 90 days;

<PAGE>   32
                                                                              27

                  (ii)     prepare and file with the SEC such amendments to such
registration statement and supplements to the prospectus contained therein as
may be necessary to keep such registration statement effective for such period
as may be reasonably necessary to effect the sale of such Registrable Shares,
but in no event longer than 90 days;

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

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

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

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

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

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

<PAGE>   33
                                                                              28

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

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

         (b)      Notwithstanding anything to the contrary in this Agreement, if
at any time after the filing of a registration statement (i) in the case of any
registration statement for a firm commitment underwritten offering of
Registrable Shares, before it is declared effective by the SEC, or (ii) in the
case of any other registration statement, before or after it is declared
effective by the SEC, the Company determines, in its reasonable good faith
business judgment, that such registration and the offering of Registrable Shares
covered by such registration would interfere with or otherwise adversely affect
any financing, acquisition, corporate reorganization or other material
transaction or development involving the Company or any of its Affiliates or
require the Company to disclose material matters regarding itself or such
Affiliates that otherwise would not be required to be disclosed at such time,
then the Company may require the suspension of the distribution of any
Registrable Shares (a "Blackout Period") by giving notice to Shareholder. Any
such notice need not specify the reasons for such suspension if the Company
determines, in its reasonable good faith business judgment, that doing so would
interfere with or adversely affect such transaction or development or would
result in the disclosure of material nonpublic information. In the event that
such notice is given, then until the Company has determined, in its reasonable
good faith business judgment, that such registration and distribution would no
longer materially interfere with the matters described in the preceding sentence
and has given notice thereof to Shareholder, the Company's obligations under
this Article 9 will be suspended. The Company shall extend the period of time
the Company is required to maintain effective any registration statement
required pursuant to clauses (i) and (ii) of paragraph (a) of this Section 9.3
by a length of time equal to the aggregate length of the Blackout Periods. In
the event of any suspension of a registration pursuant to this Section 9.3(b),
the selling Mischief Stockholder Group shall be entitled to withdraw from such
registration upon written notice to the Company.

         (c)      The Company's obligations to the Mischief Stockholder Group
under this Article 9 will be conditioned on compliance with the following in
connection with the preparation, filing and use of a Registration Statement:

<PAGE>   34
                                                                              29

                  (i)      Shareholder, the Mischief Stockholder Group and their
respective Affiliates will cooperate with the Company in connection with the
preparation of the applicable registration statement, and for so long as the
Company is obligated to keep such registration statement effective, Shareholder,
the Mischief Stockholder Group and their respective Affiliates will provide to
the Company, in writing in a timely manner, for use in such registration
statement (and expressly identified in writing as such), all information
regarding Shareholder, the Mischief Stockholder Group and their respective
Affiliates and such other information as may be required by applicable law to
enable the Company to prepare such registration statement and the related
prospectus covering the applicable Registrable Shares owned by the selling
Mischief Stockholder Group and to maintain the currency and effectiveness
thereof, so long as the Company executes a confidentiality agreement in form and
substance reasonably satisfactory to Shareholder in the event any confidential
information is requested by the Company;

                  (ii)     Shareholder, the Mischief Stockholder Group and their
respective Affiliates will permit the Company and its representatives and agents
to examine such documents and records and will supply in a timely manner any
information as they may reasonably request in connection with the offering or
other distribution of Registrable Shares by the Mischief Stockholder Group;

                  (iii)    Shareholder, the Mischief Stockholder Group and their
respective Affiliates will enter into such agreements with the Company and any
broker-dealer or similar securities industry professional containing
representations, warranties, indemnities and agreements as are customarily
entered into and made by a seller of securities and such seller's controlling
shareholders with respect to secondary distributions under similar
circumstances;

                  (iv)     during such time as Shareholder, the Mischief
Stockholder Group and their respective Affiliates may be engaged in a
distribution of the Registrable Shares, Shareholder, the Mischief Stockholder
Group and their respective Affiliates will comply with all applicable laws,
including Regulation M promulgated under the Securities Exchange Act of 1934, as
amended, and, to the extent required by such laws, will, among other things: (A)
not engage in any stabilization activity in connection with the securities of
the Company in contravention of such rules; (B) distribute the Registrable
Shares acquired by it solely in the manner described in the applicable
registration statement; (C) if required by applicable law, rules or regulations,
cause to be furnished to each agent or broker-dealer to or through whom such
Registrable Shares may be offered, or to the offeree if an offer is made
directly by Shareholder, the Mischief Stockholder Group and their respective
Affiliates, such copies of the applicable prospectus (as amended and
supplemented to such date) and documents incorporated by reference therein as
may be required by such agent, broker-dealer or offeree, provided that the
Company shall provide Shareholder with an adequate number of copies thereof; and
(D) not bid for or purchase any securities of the Company; and

                  (v)      on notice from the Company of the happening of any of
the events specified in Section 9.3(a)(iv) or (v), or that, as set forth in
Section 9.3(b), requires the suspension by Shareholder, the Mischief Stockholder
Group and their respective Affiliates of the distribution of any of the
Registrable Shares owned by the Mischief Stockholder Group, then Shareholder,
the Mischief Stockholder Group and their respective Affiliates will cease
offering

<PAGE>   35
                                                                              30

or distributing the Registrable Shares owned by the Mischief Stockholder Group
until the offering and distribution of the Registrable Shares owned by the
Mischief Stockholder Group may recommence in accordance with the terms hereof
and applicable law.

         (d)      Except as otherwise provided with respect to registrations
terminated by the Company, the Company shall bear the following fees, costs and
expenses in connection with its obligations under this Article 9: all
registration, filing fees, printing expenses, all internal Company expenses and
the premiums and other costs of policies of insurance against liability arising
out of the public offering. Fees and disbursements of counsel and accountants
for Shareholder, the Mischief Stockholder Group and their respective Affiliates,
underwriting discounts and commissions and transfer taxes for Shareholder, the
Mischief Stockholder Group and their respective Affiliates and other direct
selling expenses incurred by Shareholder, the Mischief Stockholder Group and
their respective Affiliates not expressly included above shall be borne by
Shareholder, the Mischief Stockholder Group and their respective Affiliates.

         (e)      The Company shall indemnify and hold harmless each selling
Mischief Stockholder, and each Person, if any, who controls a selling Mischief
Stockholder within the meaning of the Securities Act, from and against any and
all claims, losses, damages, liabilities, costs and expenses to which the
selling Mischief Stockholder or any such controlling Person may become subject
under the Securities Act or otherwise, insofar as such claims, losses, damages,
liabilities, costs or expenses arise out of or are based on any untrue statement
or alleged untrue statement of any material fact contained in any registration
statement filed by the Company pursuant to this Article 9 which relates to
Registrable Shares owned by the selling Mischief Stockholder, any prospectus
contained therein or any amendment or supplement thereto, or arise out of or are
based upon the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances in which they were made, not misleading, except
insofar as any such claim, loss, damage, liability, costs or expense arises out
of or is based upon an untrue statement or alleged untrue statement or omission
or alleged omission so made in conformity with information furnished by
Shareholder, the Mischief Stockholder Group and their respective Affiliates or
such controlling Person specifically for inclusion in such registration
statement; provided, however, that the foregoing indemnity is subject to the
condition that, insofar as it relates to any untrue statement or alleged untrue
statement, omission or alleged omission made in a preliminary prospectus but
eliminated or remedied in a prospectus, such indemnity agreement shall not inure
to the benefit of the selling Mischief Stockholder or any Person who controls
the selling Mischief Stockholder if (A) the Company complied with all of its
notification and delivery obligations as provided herein, (B) such claim, loss,
damage, liability, cost or expense relates to the matter so eliminated or
remedied in the final prospectus and (C) the selling Mischief Stockholder or its
Affiliates failed to deliver a copy of the prospectus at or prior to the time
such action is required by the Securities Act; provided, further, that the
foregoing indemnity is also subject to the condition that, insofar as it relates
to any untrue statement or alleged untrue statement, omission or alleged
omission made in a prospectus attributable solely to facts or events which occur
after the effective date of the registration statement, which untrue statement
or alleged untrue statement, omission or alleged omission is eliminated or
completely remedied in an amendment or supplement to the prospectus, such
indemnity agreement shall not inure to the benefit of the selling Mischief
Stockholder or any Person who controls the selling Mischief Stockholder or any
of their

<PAGE>   36
                                                                              31

Affiliates, if, having previously been furnished by or on behalf of the Company
with copies of the prospectus as so amended or supplemented, in lieu thereof the
selling Mischief Stockholder or its Affiliates delivered the prospectus without
such amendment or supplement.

         (f)      Shareholder shall indemnify and hold harmless the Company and
any underwriter (as defined in the Securities Act) for the Company, and each
Person, if any, who controls the Company or such underwriter within the meaning
of the Securities Act from and against any claims, losses, damages, liabilities,
costs or expenses to which the Company or any such underwriter or controlling
Person may become subject under the Securities Act or otherwise, insofar as such
claims, losses, damages, liabilities, costs or expenses are caused by any untrue
or alleged untrue statement of any material fact contained in any registration
statement filed by the Company pursuant to this Article 9 which relates to
Registrable Shares owned by any Mischief Stockholder or any of its Affiliates,
any prospectus contained therein or any amendment or supplement thereto, and
arise out of or are based upon the omission or the alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances in which they were made, not
misleading, in each case to the extent, but only to the extent, that such untrue
statement or alleged untrue statement or omission or alleged omission was so
made in reliance upon and in strict conformity with written information
furnished by Shareholder, the Mischief Stockholder Group or their respective
Affiliates specifically for inclusion in such registration statement, prospectus
or amendment or supplement thereto).

         (g)      Except to the extent otherwise provided in this Section
9.3(g), a party obligated to provide indemnification under Section 9.3(e) or (f)
shall reimburse each party entitled to such indemnification the costs of
investigating and defending any claim, loss, damage, liability, cost or expense
giving rise to such indemnification obligation. Promptly after receipt by an
indemnified party pursuant to the provisions of paragraphs (e) and (f) of this
Section 9.3 of notice of commencement of any action involving the subject matter
of the foregoing indemnity provisions, such indemnified party will, if a claim
thereof is to be made against the indemnifying party pursuant to the provisions
of said paragraph (e) and (f) promptly notify the indemnifying party of the
commencement thereof, but the omission to so notify the indemnifying party will
not relieve the indemnifying party from any liability which it may have to any
indemnified party, except to the extent that the indemnifying party is
materially prejudiced by the failure to give such prompt notice. If such action
is brought against any indemnified party and it notifies the indemnifying party
of the commencement thereof, the indemnifying party shall have the right to
participate therein, and, to the extent that it may wish, jointly with any other
indemnifying party similarly notified, to assume the defense thereof so long as
it agrees to accept full responsibility to indemnify and hold harmless the
indemnified party in accordance herewith in respect of such action. After notice
from the indemnifying party to such indemnified party of its election so to
assume the defense thereof, the indemnifying party will not be liable to such
indemnified party pursuant to the provisions of said paragraph (e) and (f) for
any legal or other expense subsequently incurred by such indemnified party in
connection with the defense thereof other than reasonable costs of
investigation, unless (i) the indemnified party shall have been advised by its
counsel that use of the same counsel to represent both the indemnifying party
and the indemnified party would present a conflict of interest (which shall be
deemed to include any case where there may be a legal defense or claim available
to the indemnified party which is different

<PAGE>   37
                                                                              32

from or additional to those available to the indemnifying party) or (ii) the
indemnifying party shall fail vigorously to defend or prosecute such claim or
demand within a reasonable time, in which case the fees of counsel for the
indemnified party shall be for the account of the indemnifying party and the
indemnifying party shall not have the right to direct the defense of such action
on behalf of the indemnified party. The indemnifying party shall not be liable
for any settlement of any proceeding effected without its written consent but if
settled with such consent, or if there be a final judgment for the plaintiff,
the indemnifying party shall indemnify and hold harmless such indemnified
parties from and against any loss or liability (to the extent stated above) by
reason of such settlement or judgment. No indemnifying party shall, without the
prior written consent of the indemnified party, effect any settlement of any
pending or threatened proceeding in respect of which any indemnified party is or
could have been a party and indemnity could have been sought hereunder by such
indemnified party, unless such settlement includes an unconditional release of
such indemnified party from all liability arising out of such proceeding.

         (h)      The registration rights granted to the Mischief Stockholder
Group pursuant to this Article 9 are not assignable. Any assignment not
permitted hereunder shall be null and void ab initio.

         (i)      If the indemnification provided for under Sections 9.3(e) or
(f), as applicable, is unavailable to or insufficient to hold the indemnified
party harmless under such Section in respect of any claim, loss, damage,
liability, cost or expense referred to therein (a "Liability") for any reason
other than as specified therein, then the indemnifying party shall contribute to
the amount paid or payable by such indemnified party as a result of such claims,
losses, damages, liabilities, costs or expenses (i) in such proportion as is
appropriate to reflect the relative benefits received by the indemnifying party
on the one hand and such indemnified party on the other from the subject
offering or distribution or (ii) if the allocation provided by clause (i) of
this sentence is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i)
of this sentence but also the relative fault of the indemnifying party on the
one hand and such indemnified party on the other in connection with the
statements or omissions which resulted in such Liability as well as any other
relevant equitable considerations. The relative benefits received by the
indemnifying party on the one hand and the indemnified party on the other hand
shall be deemed to be in the same proportion as the net proceeds of the offering
or other distribution (after deducting expenses) received by the indemnifying
party bears to the net proceeds of the offering or other distribution (after
deducting expenses) received by the indemnified party. The relative fault shall
be determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by (or omitted to be supplied
by) the Company or the selling Mischief Stockholder Group, the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission, the relative benefits received by each party from
the sale of the Registrable Shares and any other equitable considerations
appropriate under the circumstances. The amount paid or payable by an
indemnified party as a result of the Liability referred to above in this Section
9.3(i) shall be deemed to include any legal or other expenses reasonably
incurred by such indemnified party in connection with investigating or defending
any such action or claim. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of

<PAGE>   38
                                                                              33

the Securities Act) shall be entitled to contribution from any person who was
not guilty of such fraudulent misrepresentation.

         (j)      Notwithstanding anything herein to the contrary, the parties
agree that the obligations and liability of the selling Mischief Stockholder
Group with respect to any registration in which any Mischief Stockholder
participates pursuant to Section 9.1 or 9.2 whether from indemnification
pursuant to Section 9.3(f), contribution pursuant to Section 9.3(i), or
otherwise shall not in any event exceed, in the aggregate, the amount of net
proceeds received by such selling Mischief Stockholder from the sale of the
Registrable Shares sold by such Mischief Stockholder in such registration.

                                   ARTICLE 10

                            SURVIVAL; INDEMNIFICATION

         10.1.    Survival. All representations, warranties, covenants and
agreements contained in this Agreement or in any schedule, exhibit, certificate,
agreement, document or statement delivered pursuant hereto shall survive the
assignment and assumption of the Acquired Assets and the Assumed Liabilities and
the Mischief Share Closing (if it occurs) and not be affected in any respect by
any investigation conducted by any party hereto; provided, however, that the
representations and warranties set forth in Articles 5, 6 and 7 will terminate
and expire on the second anniversary of the date hereof. After a representation
and warranty has terminated and expired, no indemnification will or may be
sought pursuant to this Article 10 on the basis of a breach or inaccuracy of
that representation and warranty by any Person who would have been entitled
pursuant to this Article 10 to indemnification on the basis of a breach or
inaccuracy of that representation and warranty prior to its termination and
expiration; provided that in the case of each representation and warranty that
will terminate and expire as provided in this Section 10.1, no claim presented
in writing for indemnification pursuant to this Article 10 on the basis of a
breach or inaccuracy of that representation and warranty prior to its
termination and expiration will be affected in any way by that termination and
expiration.

         10.2.    Indemnification by Shareholder. Shareholder shall indemnify
and hold MTVNO and its partners and their respective shareholders, employees,
officers, directors, agents and Affiliates (and following the Mischief Share
Closing, Mischief)(collectively, the "MTVNO Indemnified Parties"), without
duplication, harmless from and against, and agree promptly to defend any such
Indemnified Party from and reimburse any such Indemnified Party for, any and all
Losses which any such Indemnified Party may suffer or incur, or become subject
to, arising out of or resulting from, without duplication:

         (a)      any breach or inaccuracy as of the date of this Agreement, as
of the Mischief Share Closing Date or as of the Put Closing Date of any of the
representations and warranties made by Shareholder in or pursuant to this
Agreement or in any instrument or certificate delivered by Mischief or
Shareholder in accordance herewith;

<PAGE>   39
                                                                              34

         (b)      any failure by Mischief or Shareholder to carry out, perform,
satisfy and discharge any of its covenants, agreements, undertakings,
liabilities or obligations under this Agreement; and

         (c)      any liability or obligation of Mischief which is not included
in the Assumed Liabilities.

         10.3.    Indemnification by MTVNO. MTVNO shall indemnify and hold
Mischief and its shareholders, employees, officers, directors, agents and
Affiliates (the "Mischief Indemnified Parties"), harmless from and against, and
agree promptly to defend any such Indemnified Party from and reimburse any such
Indemnified Party for, any and all Losses which any such Indemnified Party may
suffer or incur, or become subject to, arising out of or resulting from, without
duplication:

         (a)      any breach or inaccuracy as of the date of this Agreement of
any of the representations and warranties made by MTVNO in or pursuant to this
Agreement or in any instrument or certificate delivered by it in accordance
herewith;

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

         (c)      the Assumed Liabilities (but only to the extent so assumed).

         10.4.    Indemnification Procedures. Any party asserting a right to
indemnification under Section 10.2 or 10.3 shall so notify in writing the
applicable Person or Persons required hereunder to provide indemnification
pursuant to this Article 10. The indemnified party's failure to so notify the
indemnifying party of any such matter shall not release the indemnifying party,
in whole or in part, from its obligations to indemnify under this Article 10
except to the extent that the indemnifying party is materially prejudiced by
such failure. If the facts giving rise to such indemnification shall involve any
actual or threatened claim or demand by or against a third party, the
indemnifying party shall be entitled to control the defense or prosecution of
such claim or demand in the name of the indemnified party, with counsel
reasonably satisfactory to the indemnified party, if (x) it notifies the
indemnified party in writing of its intention to do so within 20 days of its
receipt of such notice, without prejudice, however, to the right of the
indemnified party to participate therein through counsel of its own choosing,
which participation shall be at the indemnified party's expense unless (i) the
indemnified party shall have been advised by its counsel that use of the same
counsel to represent both the indemnifying party and the indemnified party would
present a conflict of interest (which shall be deemed to include any case where
there may be a legal defense or claim available to the indemnified party which
is different from or additional to those available to the indemnifying party) or
(ii) the indemnifying party shall fail to defend or prosecute in good faith such
claim or demand within a reasonable time, in which case the reasonable fees of
counsel for the indemnified party shall be for the account of indemnifying party
and the indemnifying party shall not have the right to direct the defense of
such action on behalf of the indemnified party, (y) it agrees to accept full
responsibility indemnify and hold harmless the indemnified party in accordance
herewith in respect of the claim or demand and (z) the indemnifying party has
sufficient financial resources in order to

<PAGE>   40
                                                                              35

indemnify for the full amount of any potential liability in connection with such
claim. Whether or not the indemnifying party chooses to defend or prosecute such
claim, the parties hereto shall cooperate in the prosecution or defense of such
claim and shall furnish such records, information and testimony and attend such
conferences, discovery proceedings, hearings, trials and appeals as may
reasonably be requested in connection therewith. No party shall settle or permit
the settlement of any such third party claim or action without the prior written
consent of the other party, unless the settlement contains a full release of the
other party from all liabilities or obligations with respect to the related
claim or action.

         10.5.    No Contribution from Mischief. Notwithstanding anything
contained in this Agreement to the contrary, Shareholder acknowledges and agrees
that it has no right of contribution from or remedy against Mischief as a result
of any indemnification it is required to make under or arising out of a breach
of any warranty or representation relating to Mischief or covenant of Mischief
in this Agreement or in any certificate, document or other instrument delivered
in connection herewith or therewith, and Shareholder hereby releases, waives and
forever discharges any right to indemnification, reimbursement or contribution
that he may have at any time against Mischief arising out of the
representations, warranties, covenants and agreements contained in this
Agreement or in any certificate, document or other instrument delivered in
connection herewith or therewith.

         10.6.    Limitations on Indemnification . Notwithstanding anything to
the contrary in this Agreement, (i) Shareholder shall not be responsible for any
Losses under Section 10.2(a) and (c), excluding indemnification claims for
Losses arising out of any inaccuracy or breach of the representations and
warranties contained in Section 5.13 or any Losses arising from Mischief's or
Shareholder's failure to satisfy the liabilities set forth on the Closing
Liability Schedule, until the cumulative aggregate amount of such Losses
(excluding any such Losses to the extent recovered by MTVNO from any third party
under any contract with such party or under any applicable insurance policy (net
of any increase in insurance premiums)) exceeds $100,000, and then only to the
extent of such excess, and (ii) no group of indemnifying parties' cumulative
indemnity obligations under any of Sections 10.2(a) and (c), excluding
indemnification claims for Losses arising out of any inaccuracy or breach of the
representations and warranties contained in Sections 5.1, 5.2 and 5.3, shall
exceed $2,500,000. For purposes of this Article 10, Losses shall be determined
on a net after-tax basis. MTVNO agrees that it will first satisfy the
indemnification obligations of Shareholder under this Article 10 by exercising
its rights under, and subject to the terms of, the Pledge Agreement. Each party
hereto agrees that, prior to the IPO, the value of the Pledged Shares for
purposes of satisfaction of Losses pursuant to this Article 10 will be equal to
the greater of (x) $15 per Partnership Unit (adjusted to reflect any split,
combination or reclassification of Partnership Units after the date hereof) and
(y) the fair market value of such Partnership Units as determined in good faith
by the board of directors of the Company.

         10.7.    Exclusive Remedy. The remedies provided for in this Article 10
shall be the sole remedies, contractual or otherwise, of the indemnified parties
and shall preclude assertion by the indemnified parties of any other rights or
the seeking of any other remedies against the indemnifying parties with respect
to this Agreement and the transactions contemplated hereby; provided, however,

                                   ARTICLE 11

                                  MISCELLANEOUS

         11.1.    Table of Contents; Headings. The table of contents and
headings of the Articles, Sections and other subdivisions 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.

         11.2.    Governing Law. This Agreement and the rights and obligations
of the parties hereto, and any claims or disputes relating thereto, shall be
governed by and construed under and in accordance with the laws of the State of
New York, without regard to the choice of law rules thereof.

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

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

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

         11.6.    Entire Agreement. This Agreement and the other Operative
Agreements contain the entire agreement of the parties with respect to the
subject matter hereof and supersede any and all prior agreement and
understandings, whether written or oral, with respect to the subject matter
hereof.

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

         11.8.    Parties in Interest; Limitation on Rights of Others. MTVNO may
assign its rights and obligations under this Agreement to one or more Affiliates
of MTVNO; provided, that no such assignment shall relieve MTVNO of its
obligations hereunder and any such assignment shall be approved by Viacom. No
party to this Agreement may assign any of its rights or delegate any of its
obligations under this Agreement except as specifically provided in this Section
11.8. The terms of this Agreement shall be binding upon and inure to the benefit
of the parties hereto and their respective heirs, successors (including any
successor to the business

                                                                              37

of MTVNO) and permitted assigns. Any assignment of rights hereunder in violation
hereof shall be null and void ab initio. Except for the provisions of Article 10
and Section 8.5 hereunder, nothing in this Agreement, whether express or
implied, shall be construed to give any Person (other than the parties hereto
and their heirs, successors (including any successor to the business of MTVNO)
and permitted assigns) any legal or equitable right, remedy or claim under or in
respect of this Agreement or any covenants, conditions or provisions contained
herein. MTVNO will cause the Company to perform all of the Company's obligations
hereunder and under the other Operative Agreements. Notwithstanding any
provision herein to the contrary, the Company may assign any of its rights and
obligations, including such rights and obligations under Article 3 hereof,
without the consent of Mischief or Shareholder, to an Affiliate of the Company;
provided, that no such assignment shall relieve MTVNO of its obligations with
respect to the Company hereunder.

         11.9.    Waivers; Remedies. The observance of any term of this
Agreement may be waived (either generally or in a particular instance and either
retroactively or prospectively) by the party or parties entitled to enforce such
term, but any such waiver shall be effective only if in a writing signed by the
party or parties against which such waiver is to be asserted and only in the
specific instance and for the specific purpose for which given. Except as
otherwise provided herein, no failure or delay of any party in exercising any
power or right under this Agreement shall operate as a waiver thereof, nor shall
any single or partial exercise of any such right or power, or any abandonment or
discontinuance of steps to enforce such right or power, preclude any other or
further exercise thereof or the exercise of any other right or power.

         11.10.   Further Assurances. After the date hereof, for no further
consideration, Mischief and Shareholder shall perform all such other acts and
shall execute, acknowledge and deliver all such assignments, transfers, consents
and other documents as MTVNO or its counsel may reasonably request (i) to vest
in MTVNO, and protect MTVNO's right, title and interest in, and enjoyment of,
the business of Mischief and the Acquired Assets or (ii) to carry out the intent
and purposes of this Agreement and give effect to the exercise by MTVNO of its
rights hereunder. In accordance with the foregoing, promptly following the date
of this Agreement, but in no event later than the Mischief Share Closing Date,
Mischief or Shareholder shall provide MTVNO with evidence of satisfaction of the
obligations and liabilities of Mischief indicated on the Closing Liability
Schedule. Furthermore, in order to effectuate the intent of this Section 11.10,
and without limiting any of the provisions hereof, but subject to the provisions
of Section 10.4, Mischief hereby constitutes and appoints MTVNO, its successors
and assigns and each of the officers and employees thereof, its true and lawful
attorneys-in-fact, with full power of substitution, in the name of MTVNO or in
the name of Mischief or otherwise, but for the benefit of MTVNO:

         (a)      to demand and collect, to endorse and deposit, or to
compromise, settle or release all property of any character and any other items
conveyed, transferred and assigned hereby;

         (b)      to endorse and deposit checks and drafts and to demand and
collect, compromise, settle or release all claims and rights conveyed,

         (c)      to institute and prosecute all proceedings which any such
attorney-in-fact may deem appropriate in order to collect, assert or enforce any
claim, right, title and interest of Mischief of any kind in or to the Acquired
Assets conveyed, transferred or assigned hereby;

         (d)      to defend, compromise or settle any and all actions, suits or
proceedings in respect of the Acquired Assets conveyed, transferred and assigned
hereby; and

         (e)      to undertake any and all other acts or execute any instruments
which any such attorney-in-fact may deem proper in order to provide MTVNO with
the use and benefit of the Acquired Assets conveyed, transferred and assigned
hereby.

         Mischief acknowledges that the foregoing powers are coupled with an
interest and may not be revoked in any manner or for any reason. MTVNO shall be
entitled to retain for its own account any amounts collected pursuant to the
foregoing powers, including any amounts payable as interest in respect thereof.
No attorney-in-fact shall bear any liability for any action or failure to act
pursuant hereto, except for such attorney-in-fact's gross negligence or willful
misconduct.

         11.11.   Public Announcements. No party hereto shall make, or shall
permit any of its Affiliates to make, any public announcement about the
transactions contemplated by this Agreement without the prior written consent of
the other parties hereto, which consent shall not be unreasonably withheld or
delayed.

         11.12.   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 consummated or contemplated hereby;
provided, however, that Shareholder shall be responsible for all such costs and
expenses of Mischief; provided, further, that MTVNO shall be solely responsible
for and shall pay any sales, use, transfer or similar Taxes imposed upon the
conveyance of the Acquired Assets contributed hereby.
