2.1(c), such MTVi Named Site and web page to be chosen by MTVi in its sole
discretion based on the genre of such artist, the genre of the Application and
any desire to provide branded product or event tie-ins (the "Featured
Application").  Any Featured Application that is linked from any home page of an
MTVi Named Site shall be exclusive to MTVi, and shall not be licensed by Beatnik
to appear on any other Website, whether controlled by Beatnik or otherwise, for
a period of forty-five (45) days beginning on the day the link to the

Agreement.

     (b)  Throughout the Term, MTVi shall place at least one hyperlink that

<PAGE>

                                                                               5

promotional activities related to such Featured Application known to Beatnik.
MTVi shall select one, two or three of such Top Line Artists for such Featured
Application for the month within ten (10) business days of its receipt of the
Artist List. Beatnik shall use commercially reasonable efforts to deliver one
Featured Application monthly within thirty (30) days ("Development Period")
after MTVi's notice to Beatnik of MTVi's selection of Top Line Artist. Once MTVi
has delivered such notice of its selection of Top Artists to Beatnik, as
information on additional limitations with respect to such choices becomes
available to Beatnik, Beatnik shall promptly provide MTVi written notice of such
additional limitations applicable to the corresponding selections for the
Featured Application. MTVi may reject any of the selections for the Featured
Application based only on (i) any such additional limitations provided in the
most recent written notice from Beatnik or (ii) combination of such additional
limitations provided in the most recent written notice from Beatnik together
with the limitations previously disclosed to MTVi by Beatnik, so long as such
rejection is provided within five (5) business days after MTVi's receipt of such
written notice of the limitations on which MTVi is basing such rejection;
provided, however, it is agreed MTVi cannot base any such rejection on
--------  -------
limitations or parameters that MTVi has otherwise agreed to in this Agreement.
If MTVi rejects all of its selections for the Featured Application (for a month)
pursuant to the foregoing, then (x) Beatnik will use commercial reasonable
efforts to propose other choices of Top Line Artists for the Featured
Application, (y) MTVi will use commercially reasonable efforts to propose one
artist for a Featured Application, and (z) if the delivery of the Featured
Application is not made within the applicable Development Period, MTVi will be
deemed to have fulfilled the obligations under Section 2.1(b) during such 30 day
period under this Agreement for the purposes of determining whether the related
milestone event has occurred. For the purposes of this Section 2.1(c) only,
written notice may be provided by a E-mail or facsimile in each case with
receipt thereof confirmed, in addition to the methods specified in Section 18.
The current running promotions with Lucy Pearl and Smash Mouth are deemed to
satisfy Beatnik's obligations under the first two months of the Term for
purposes of Section 2.1 and when MTVi has complied with the requirements of
Section 2.1(b) with respect to any such Featured Application, MTVi shall be
deemed to have met its obligations with respect to such Featured Application and
the related milestone event shall be deemed to have occurred.

     (d)  All Featured Applications shall be compatible with and playable by
the standard Beatnik plug-in module or some other Beatnik software module made
available to the public by Beatnik at no charge.

     (e)  Beatnik shall have the right to disclose to its potential third party
licensors that the Featured Application may be displayed via the MTVi Affiliate
Sites and that such MTVi Affiliate Sites may link to such Featured Application.

pursuant to this Section 2.1 shall include the name and logo of Beatnik, in
compliance with Beatnik's Trademark Usage Guidelines attached hereto as Schedule
C.

     (g)  In any monthly period during the term that Beatnik fails to deliver a
Featured Application from among MTVi's choices made by MTVi in accordance with
the terms hereunder, due to reasons other than any delay substantially resulting
from MTVi's failure to provide timely notice of MTVi's selections of Top Line
Artists, MTVi shall be deemed to have met its obligations under Section 2.1(b)
for such month and for the purposes of determining whether the related milestone
event has occurred.  Any failure of Beatnik to adequately host the Featured
Application shall not in any way require MTVi to take any further action in
order to meet its obligations hereunder.  Notwithstanding anything to the
contrary herein, MTVi shall not be obligated to provide a Home Page Promotion
more than twelve (12) times in any annual period.

2.2. Co-Branded Pages.

     (a)  Within thirty (30) days after the Effective Date, MTVi shall provide
Beatnik a proposed production schedule for the design and creation of Web pages

approve the production schedule or the parties will mutually agree on an amended
production schedule for such design and creation.  The Co-Branded Pages will be
placed on one or more of the MTVi Named Sites.  The Co-Branded Pages may also be
placed on other MTVi Affiliate Sites by mutual agreement of the parties.  The
Co-Branded Pages will be continuously hosted for the duration of this agreement
and will appear and be hosted completely on the MTVi Named Site.  Except for any
Application, MTVi will have sole responsibility for hosting and maintaining the
Co-Branded Pages at its sole expense.  The Co-Branded Pages shall only be
viewable by a visitor who links to them directly from a hyperlink placed on a
MTVi Named Site or the Beatnik Website or through a stored URL (e.g., bookmark
or similar index storage mechanism).

     (b)  Each Co-Branded Page will display certain proprietary features of
both the MTVi Named Site and Beatnik, including trademarks, logos, or links to
either Beatnik Content, Applications, or MTVi content.  MTVi and Beatnik will
collaborate on the "look and feel" of the Co-Branded Pages including, but not
limited to, the display, appearance and placement of the parties' respective
names and/or brands and of advertising displayed on the Co-Branded Pages.  The
"look and feel" of the Co-Branded Pages shall be developed by MTVi, subject to
the reasonable approval of Beatnik. Notwithstanding the foregoing, in no case
shall MTVi be obligated to include any Beatnik Content on the Co-Branded Pages
which is co-branded with any third party without the prior written consent of
MTVi.

     (c)  MTVi shall place at least five (5) hyperlinks from five (5) different
webpages residing anywhere within the MTVi Named Sites to the Co-Branded Pages,

artists' webpages, MTVi shall permit Beatnik to include such a hyperlink on any
Application that may be linked to via such Co-Branded Page, subject to MTVi's
prior approval in regards to the

                                                                               7

hyperlink's appearance and in accordance with the rights and restrictions
contained in the grant.

     (d)  Beatnik shall host any and all Applications that are mutually agreed
upon as elements of the Co-Branded Pages.  Beatnik shall make its reasonable
efforts to furnish Applications for such purpose, including procuring any
underlying intellectual property rights necessary, and to adequately host and
maintain such Applications in the manner necessary in order for MTVi to fulfill
its obligations to Beatnik hereunder.

     (e)  As between MTVi and Beatnik, MTVi shall own the copyright in and to
the Co-Branded Pages, except the Beatnik Content, the Beatnik Technology,
Beatnik Marks and Applications owned by Beatnik or its licensors, as applicable.
Nothing in the foregoing shall grant or transfer ownership or any right to the
Beatnik name and logo, Beatnik Content, Beatnik Technology or Applications to

interest in and to the Beatnik Content, Beatnik Technology, Beatnik Marks and

Site, as determined by MTVi in its sole discretion (the "S-Track Clips").  The
S-Track Clips shall be compatible with and playable by the standard Beatnik
plug-in or some other Beatnik software made available to the public at no cost.
Beatnik will make available such S-Track Clips within five (5) days of the
Effective Date.  In no case shall an S-Track Clip contain any sound component

Track Clip is being used by such MTVi Affiliate Site.

     (b)  MTVi will Sonify at least ten (10) webpages on the MTVi Named Sites,
none of which may be more than two (2) clicks below the homepage of such Site.

judgment of MTVi and Beatnik and not to be unreasonably withheld or delayed, and
(ii) standard, generally applicable technical limitations.

     (b)  MTVi reserves the right to redesign or modify the organization,
structure, "look and feel," navigation and other elements of any portion of the
MTVi Affiliate Sites.  In the event such modifications materially affect the
promotional placements for Beatnik described above, MTVi will promptly notify
Beatnik and provide Beatnik with a comparable package of promotional placements
which are reasonably satisfactory to Beatnik.  No such redesign or modification
to the MTVi Affiliate Sites provided for in this Section will affect the
Impressions guarantee in this Agreement.

     (c)  No Beatnik button, banner, or logo:  (i) shall have dimensions larger
than 468 pixels wide by 60 pixels high, (ii) shall contain more than six seconds
of "looped" animation, (iii) be a file size of no greater than 20K, or (iv)

and regulations, including, without limitation, consumer protection laws and
rules and regulations governing product claims, truth in labeling, and false
advertising. The foregoing limitations on the Beatnik buttons, banners and logos
are based on the industry standard, and if the industry standard changes, then
the limitations will be adjusted accordingly, subject to the mutual agreement of
the parties not to be unreasonably withheld.

     (d)  During the Term, MTVi shall deliver at least 2 Million Impressions
per month in aggregate; provided, however, that at least 80% of such Impressions

Impressions delivered during the previous month.
<PAGE>

                                                                               9

     (e)  In the event that MTVi fails to deliver the guaranteed number of
Impressions specified above, MTVi will "make good" the shortfall by providing
Beatnik with a number of substitute Impressions equal to such shortfall by
providing additional hyperlinks to Beatnik content on the MTVi Affiliate Sites
as soon as reasonably possible, but in no event later than sixty (60) days after
the month in which such shortfall occurred; provided that if the shortfall
occurs in the number of Impressions applicable to the MTVi Named Sites, only
Impressions on such MTVi Named Sites may be used to "make good" the shortfall.
If MTVi is unable to "make good" the shortfall within such sixty (60) day
period, MTVi will provide Beatnik with an equivalent number of Impressions as
part of the additional advertising provided to Beatnik pursuant to Section 4,
without charge.  The foregoing "make good" provision sets forth the entire
liability of MTVi, and Beatnik's sole remedy, for MTVi's breach of its
guaranteed Impression obligations.

Branded Pages contain a hyperlink to another Application, such linked

appear on any Application accessed through the Co-Branded Pages shall comply
with the requirements of any MTVi Affiliate Site e-commerce contractual
requirements.  No Application accessed from the Co-Branded Pages will contain
any advertising other than as expressly permitted herein.  At the time any
Featured Application or any other Application linked to by the Co-Branded Pages

User with an announcement that the User has the option to sign-up for a
newsletter mailing list for an MTVi related newsletter.

press release announcing the progress of any of the activities described in this
Agreement, including that Beatnik is the featured technology platform for user
interactive music remix web browsing tools for MTVi. Beatnik shall provide MTVi
with quotes and product specifications for the press release. Any such press
release shall be subject to Beatnik's comments and approval in its sole
discretion. Any press release mutually agreed by prior written consent of both
parties shall be promptly released. Upon execution of this Agreement, MTVi and
Beatnik shall prepare and release a press release announcing this relationship,
the content of which will be mutually approved by the prior written consent of
both parties. Notwithstanding the foregoing, each party agrees that it shall not
use the name, logo or otherwise refer to the other party or the existence of
this agreement (directly or indirectly) in any media release, public
announcement, public disclosure or promotional campaign without the prior
written consent of the other party, which consent shall not be unreasonably
withheld, except as required by law. Each party further agrees that no press
release shall be released if either

financial statements and business records relevant to the transactions set forth

accrued interest running from the date payments should have been made had the

the heading "First Anniversary Milestones" or (ii) the date eighteen months
after the date hereof in the case of the event listed under the heading
"Eighteen Month Milestone," then on the date such event occurs (or is deemed to

Shares shall no longer be subject to forfeiture to Beatnik under this Agreement
and Beatnik shall, within 10  business days, cause the legend referred to in

Shares.  During the period that any Share is subject to forfeiture by Beatnik
under this Agreement, such Share shall be referred to herein as a "Restricted
Share."

     (d)  If a milestone event does not occur or has not been satisfied and

result of) Beatnik's action or inaction or the occurrence of an event under

requisite Beatnik Content, Application, Mixman Studio or Beatnik Technology to
MTVi, then for all purposes of this Agreement the milestone event shall be
deemed to have occurred.

     (e)  (i)   With respect to any Restricted Share, for the period from the
date hereof until the date on which any such Restricted Share is no longer
subject to forfeiture to Beatnik pursuant to Section 22(b) or (c) hereof, MTVi
may not sell, transfer, pledge, or otherwise encumber or dispose of such
Restricted Share and such Restricted Share shall not be transferable, including,
but not by way of limitation, by execution, levy, garnishment, attachment,
pledge, or in any other similar manner.

          (ii)  The Shares shall not be transferred except in accordance with
this Agreement (including pursuant to Section 3.6 of the Stock Purchase
Agreement which is incorporated herein pursuant to Section 22(a)) or the Amended
and Restated Rights Agreement, dated as of the date hereof by and among Beatnik
and the shareholders listed on Exhibit A thereto, as each may be amended,
modified and supplemented from time to time.

     (f)  If there is a dispute between the parties as to whether a milestone
event has occurred, is deemed to have occurred or has been satisfied or waived,
the parties will arrange for Lorraine Harriton and Nicholas Butterworth to
discuss the matter and attempt to resolve any dispute.

     (g)  The stock certificates evidencing the Shares shall be delivered to
MTVi on the date hereof.  All certificates representing Restricted Shares shall
bear the following legend reflecting the applicability of this Agreement to the
Restricted Shares represented by such certificate.  Beatnik shall cause such
legend to be removed from the certificates representing each Restricted Share on
the date such share is no longer subject to forfeiture by Beatnik pursuant to
Section 22(b) or (c) hereof.

          THIS CERTIFICATE IS SUBJECT TO, AND IS TRANSFERABLE ONLY UPON
          COMPLIANCE WITH, THE PROVISIONS OF THE AGREEMENT AMONG MTVI AND
          BEATNIK DATED MARCH 10, 2000.  SUCH AGREEMENT PROHIBITS THE TRANSFER
          OF THESE SHARES UNTIL CERTAIN MILESTONES ARE MET.  ANY TRANSFER OF
          THESE SHARES IN VIOLATION OF SUCH AGREMEENT SHALL BE NULL AND VOID.  A
          COPY OF THE ABOVE REFERENCED AGREEMENT IS ON FILE AT THE PRINCIPAL
          OFFICES OF BEATNIK.

     (h)  The stock certificates evidencing the Shares that are delivered
hereunder shall bear restrictive legends to the extent required by Section 3.7
of the Stock Purchase Agreement which is incorporated herein pursuant to Section
22(a).

     (i)  If MTVi fails to comply with any of its obligations under this
Agreement and such obligations comprise Milestone Events listed on Schedule E,
then Beatnik's sole remedy with respect to such noncompliance by MTVi shall be
the forfeiture of Restricted Shares pursuant to this Section 22.

                                                                              21

23.  Miscellaneous.

     (a)  This Agreement contains the entire understanding of the parties
hereto relating to the subject matter hereof and cannot be changed or terminated
except by an instrument signed by both an officer of MTVi and an officer of
Beatnik.  This Agreement supersedes all prior and contemporaneous
understandings, agreements and discussions between the parties with respect to
the subject matter hereof, including without limitation, the letter agreement
between the parties dated as of February 16, 2000.  A waiver by either party of
any term or condition of this Agreement in any instance shall not be deemed or
construed as a waiver of such term or condition for the future, or of any
subsequent breach thereof. All remedies, rights, undertakings, obligations and
agreements contained in this Agreement shall be cumulative and none of them
shall be in limitation of any other remedy, right, undertaking, obligation or
agreement of either party.

     (b)  Notwithstanding anything to the contrary herein, the parties hereto
shall be deemed independent contractors and nothing herein shall be construed as
establishing a joint venture or partnership.

     (c)  This Agreement shall be deemed entered into the State of New York,
and the validity, interpretation and legal effect of this Agreement shall be
governed by the laws of the State of New York applicable to contracts entered
into and performed entirely within the State of New York, with respect to the
determination of any claim, dispute or disagreement which may arise out of the
interpretation, performance, or breach of this Agreement.

     (d)  The parties hereto are sophisticated and have had the opportunity to
be represented by lawyers throughout the negotiation of this Agreement.  As a
consequence, the parties do not believe that the presumptions of any laws or
rules relating to the interpretation of contracts against the drafter of any
particular clause should be applied in this case and therefore waive their
effects.

     (e)  This Agreement shall not become effective until executed by the
parties hereto.

     (f)  Each party shall bear its own legal fees incurred in connection with
the transactions contemplated hereby, provided, however, that if any party to
this Agreement seeks (i) to enforce its rights under this Agreement by legal
proceedings or otherwise or (ii) damages arising from and relating to a breach
of any representation, warranty, covenant or agreement made hereunder, the non-
prevailing party shall pay all costs and expenses incurred by the prevailing
party, including, without limitation, all reasonable attorneys' fees.

     (g)  This Agreement may be executed in one or more counterparts, each of
which shall be deemed an original, and all of which, when taken together, shall
constitute one and the same instrument.

                           Trademark Usage Guidelines

BEATNIK TRADEMARK USAGE GUIDELINES
----------------------------------

Beatnik's Trademarks and Logos
------------------------------

     The following words and logos are trademarks of Beatnik, Inc. in the United
States and/or other countries:

     "Beatnik(R)"

     "Mixman(R)"

     Beatnik Logo

     The foregoing shall be referred to herein, collectively, as the "Beatnik
Marks."

Guidelines for Usage
--------------------

     Beatnik has established the following set of Guidelines to be followed in
all collateral, advertising, and related activities in which Beatnik's logo and
trademarks are used.

Graphic Element
---------------

     Always use production-quality art (electronic or camera-ready) to reproduce
the Beatnik name and/or logo.

Trademark Requirements
----------------------

1.  At the first mention of a Beatnik trademark in the body or printed or on-
line material, proper notice of trademark ownership ( e.g.  or (R)) must appear.
If the first mention is in a headline, the  or (R) does not have to appear at
that mention, provided there is text following where the notice does appear.

2.  When writing about Beatnik, its products or technology, trademarks must be
used as adjectives.

3.  Advertising and all other printed materials must include credit lines for
Beatnik products and/or technologies.  If more than one Beatnik trademark is
used, all trademarks may be incorporated into one sentence.  A sample credit
line that meets these criteria is as follows:

     The following are trademarks of Beatnik, Inc.:  Beatnik(R)  Mixman(R)  and
the Beatnik logo.

Quality Control and Ownership
-----------------------------

1.  MTVi shall ensure that all advertisements, marketing materials or other
documents on which Beatnik's Marks are placed (the "Marked Materials") shall not
reflect adversely upon the good name of Beatnik. MTVi acknowledges that if the
Marked Materials distributed by MTVi were of inferior quality in design,
material or workmanship, the substantial good will which Beatnik has established
and now possesses through Beatnik's Marks would be impaired. Accordingly, MTVi
agrees that the Marked Materials shall be of high standard and

of such nature, style, appearance and quality as shall be adequate and suited to
the protection of the Marks and the goodwill associated therewith.

2.  MTVi shall submit for approval, free of cost, two samples to Beatnik of
Marked Materials prior to their dissemination or distribution in order to allow
Beatnik to determine whether (a) such Marked Materials are compliant with this
Agreement, and (b) such Marked Materials are of a high standard and of such
nature, style, appearance and quality as to be adequate and suited to the
protection and enhancement of Beatnik's Marks and the goodwill associated
therewith.  If Beatnik disapproves of any sample of the Marked Materials,
Beatnik shall provide MTVi with the specific reasons for such disapproval within
ten (10) working days after receipt thereof.  Failure of Beatnik to approve or
disapprove such samples within such ten (10) working day period shall
automatically be deemed approval thereof.  Once such Marked Materials have been
approved by Beatnik, MTVi shall not institute any material changes in the
standards, specifications or quality of the Marked Materials, without first
obtaining the approval of Beatnik to such Marked Materials as changed.

3.  Beatnik shall have the right to conduct spot checks at MTVi's facilities and
elsewhere on Marked Materials.

display such Beatnik's Marks in conjunction with, any other names or trademarks
except with Beatnik's prior written approval.  MTVi shall not use any of
Beatnik's Marks or any confusingly similar or diluting mark, term or design,
except as expressly authorized in this Agreement, and MTVi shall not attempt to
register or aid any third party in using or attempting to register any such
mark, term or design.  MTVi shall not use any of Beatnik's Marks in any manner
that will indicate that it is using such mark other than as a licensee.

6.  Refusal to submit samples, or non-compliance with this Agreement and these
guidelines will result in Beatnik's right to revoke MTVi's license to use
Beatnik's Marks.

7.  Beatnik's Marks and the goodwill associated therewith are and remain
Beatnik's exclusive property.  MTVi shall acquire no right, title or interest in
Beatnik's Marks or the goodwill associated therewith other than the limited
right to use Beatnik's Marks, as described by the express terms of this
Agreement.  All usage of Beatnik's Marks shall inure to Beatnik's benefit.  MTVi
shall not at any time do or suffer to be done any act which would impair
Beatnik's Marks or the goodwill associated therewith.  MTVi shall take any
actions reasonable requested by Beatnik, including the execution of instruments,
that may be necessary or appropriate to record Beatnik's rights to Beatnik's
Marks in any jurisdiction and perfect these rights in Beatnik's name. MTVi
agrees to take no action inconsistent with Beatnik's ownership of and interest
in Beatnik's Marks, or assist any third party in doing any of the same.  Under
no circumstances will anything in this Agreement be construed as granting, by
implication, estoppel or otherwise, any licenses or rights in Beatnik's Marks
not explicitly granted to MTVi herein.

8.  MTVi shall promptly notify Beatnik in writing of any actual or suspected
infringement of Beatnik's Marks by a third party of which MTVi becomes aware and
of any available evidence thereof.  MTVi shall cooperate, at Beatnik's expense,
with Beatnik's efforts to investigate, terminate and recover damages for any
actual or suspected infringement of the trademarks or logo.

     Beatnik reserves the right to amend this Schedule at anytime.  MTVi shall
                                              ---------
use commercially reasonable efforts to cease use and/or distribution of the
existing non-conforming Marked Materials, within ten (10) days after Beatnik
makes the amendments to this Schedule available to MTV.

legal actions or other proceedings which, in the option of MTVi, are necessary

      remaining balance of the loan at the time of your termination, including
      interest on the remaining principal at the reasonable fixed commercial
      rate of six percent (6.0%).

      3.4. Termination for Other Than Cause. In the event that the Company
           --------------------------------
      elects to terminate you for other than "Cause" (as defined below), you
      will be entitled to receive two (2) weeks of compensation for every four
