Warrant shall be exercisable at any time and from time to time during the period
(the "Exercise Period") commencing on the date hereof and ending on the earlier

and adjustments herein set forth.

          1.   Exercise of Warrant; Limitation on Exercise; Payment of Taxes.
               -------------------------------------------------------------

          1.1   Exercise of Warrant.
                -------------------

          (a)  Cash Exercise.  This Warrant may be exercised by the
               -------------
Warrantholder by (i) the surrender of this Warrant to the Company, with a duly
executed Exercise Form specifying the number of Warrant Shares to be purchased,
during normal business hours on any Business Day during the Exercise Period and
(ii) the delivery of payment to the Company, for the account of the Company, by
cash, wire transfer of immediately available funds to a bank account specified
by the Company, or by certified or bank cashier's check, of the Exercise Price
for the number of Warrant Shares specified in the Exercise Form in lawful money
of the United States of America.  The Company agrees that such Warrant Shares
shall be deemed to be issued to the Warrantholder as the record holder of such
Warrant Shares as of the close of business on the date on which this Warrant
shall have been surrendered and payment made for the Warrant Shares as
aforesaid.  A stock certificate or certificates for the Warrant Shares specified
in the Exercise Form shall be delivered to the Warrantholder as promptly as
practicable, and in any event within 10 days, thereafter.  The stock certificate
or certificates so delivered shall be in denominations of 100 shares each or
such lesser or greater denominations as may be reasonably specified by the
Warrantholder in the Exercise Form.  If this Warrant shall have been exercised
only in part, the Company shall, at the time of delivery of the stock
certificate or certificates, deliver to the Warrantholder a new Warrant
evidencing the rights to purchase the remaining Warrant Shares, which new
Warrant shall in all other respects be identical with this Warrant.  No
adjustments shall be made on Warrant Shares issuable on the exercise of this
Warrant for any cash dividends paid or payable to holders of record of Common
Stock prior to the date as of which the Warrantholder shall be deemed to be the
record holder of such Warrant Shares.

     (b)  Net Issue Exercise.  In lieu of exercising this Warrant pursuant to
          ------------------
Section 1.1(a), this Warrant may be exercised by the Warrantholder by the
surrender of this Warrant to the Company, with a duly executed Exercise Form
marked to reflect net issue exercise and specifying the number of Warrant Shares
to be purchased, during normal business hours on any Business Day during the
Exercise Period. The Company agrees that such Warrant Shares shall be deemed to
be issued to the Warrantholder as the record holder of such Warrant Shares as of
the close of business on the date on which this Warrant shall have been
surrendered as aforesaid. Upon such exercise, the Warrantholder shall be
entitled to receive shares equal to the value of this Warrant (or the portion
thereof being canceled) by surrender of this Warrant to the Company together
with notice of such election in which event the Company shall issue to
Warrantholder a number of shares of the Company's Common Stock computed as of
the date of surrender of this Warrant to the Company using the following
formula:

          X = Y(A-B)
              ------
                A

Where  X =  the number of shares of Common Stock to be issued to Warrantholder
            under this Section 1.1(b);

       Y =  the number of shares of Common Stock otherwise purchasable under
            this Warrant (at the date of such calculation);

       A =  the Fair Market Value (as defined below) of one share of the
            Company's Common Stock (at the date of such calculation);

       B =  the Exercise Price (as adjusted to the date of such calculation).

     (c)  Fair Market Value.  For purposes of Section 1.1(b) "Fair Market Value"
          -----------------
of one share of the Company's Common Stock shall mean the fair market value per
share of the Company's Common Stock on the date such notice was received by the
Company as reasonably determined by the Board of Directors of the Company;
provided, however, that in the event this Warrant is issued within fifteen days
prior to the Company's initial public offering, the fair market value shall be
equal to the price at which the Board reasonably believes such shares will be
sold to the public in such offering.

     (d)  Other Rights and Obligations.  Ownership of the Warrant and Warrant
          ----------------------------
Shares shall (i) entitle the Warrantholder to any and all rights and benefits,
and (ii) impose upon the Warrantholder the same obligations, in each case, which
are applicable to Holders of Registrable Securities, as set forth in that
certain Beatnik, Inc. Amended and Restated Rights Agreement, dated as of
December 14, 1999.

     1.2  Payment of Taxes.  The issuance of certificates for Warrant Shares
          ----------------
shall be made without charge to the Warrantholder for any stock transfer or
other issuance tax in respect thereto; provided, however, that the Warrantholder
                                       -----------------
shall be required to pay any and all taxes which may be payable in respect of
any transfer involved in the issuance and delivery of any certificate in a name
other than that of the then Warrantholder as reflected upon the books of the
Company.

                                      -2-
<PAGE>

     1.3  Information.  Upon receipt of a written request from a Warrantholder,
          -----------
the Company agrees to deliver promptly to such Warrantholder a copy of its
current publicly available financial statements and to provide such other
publicly available information concerning the business and operations of the
Company as such Warrantholder may reasonably request in order to assist the
Warrantholder in evaluating the merits and risks of exercising the Warrant and
to make an informed investment decision in connection with such exercise.

     2.   Restrictions on Transfer; Restrictive Legends.
          ---------------------------------------------

     2.1  Restrictions on Transfer; Compliance with Securities Laws.  The
          ---------------------------------------------------------
Warrant Shares issued upon the exercise of the Warrant may not be transferred or
assigned in whole or in part without compliance with all applicable federal and
state securities laws by the transferor and transferee (including the delivery
of investment representation letters and legal opinions reasonably satisfactory
to the Company, if such are requested by the Company).  The Warrantholder, by
acceptance hereof, acknowledges that this Warrant and the Warrant Shares to be
issued upon exercise hereof are being acquired solely for the Warrantholder's
own account and not as a nominee for any other party, and for investment, and
that the Warrantholder will not offer, sell or otherwise dispose of any Warrant
Shares to be issued upon exercise hereof except under circumstances that will
not result in a violation of the Securities Act or any state securities laws.
Upon exercise of this Warrant, the Warrantholder shall, if requested by the
Company, confirm in writing, in a form satisfactory to the Company, that the
Warrant Shares so purchased are being acquired solely for the Warrantholder's
own account and not as a nominee for any other party, for investment, and not
with a view toward distribution or resale.

     2.2  Restrictive Legends.  This Warrant shall (and each Warrant issued in
          -------------------
substitution for this Warrant issued pursuant to Section 4 shall) be stamped or
otherwise imprinted with a legend in substantially the following form:

     "THIS WARRANT IS NOT TRANSFERABLE. ANY SHARES ACQUIRED UPON THE
     EXERCISE OF THIS WARRANT HAVE NOT BEEN REGISTERED UNDER THE
     SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD OR
     OTHERWISE TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE
     REGISTRATION STATEMENT FILED UNDER SUCH ACT OR PURSUANT TO AN
     EXEMPTION FROM REGISTRATION UNDER SUCH ACT."

Except as otherwise permitted by this Section 2, each stock certificate for
Warrant Shares issued upon the exercise of any Warrant and each stock
certificate issued upon the direct or indirect transfer of any such Warrant
Shares shall be stamped or otherwise imprinted with a legend in substantially
the following form:

     "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
     REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY
     NOT BE SOLD OR OTHERWISE TRANSFERRED EXCEPT PURSUANT TO AN
     EFFECTIVE REGISTRATION STATEMENT FILED UNDER SUCH ACT OR PURSUANT
     TO AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT."

                                      -3-
<PAGE>

     Notwithstanding the foregoing, the Warrantholder may require the Company to
issue a stock certificate for Warrant Shares without a legend if (i) such
Warrant Shares, as the case may be, have been registered for resale under the
Securities Act or sold pursuant to Rule 144 under the Securities Act (or a
successor rule thereto) or (ii) the Warrantholder has received an opinion of
counsel reasonably satisfactory to the Company that such registration is not
required with respect to such Warrant Shares.

     3.   Reservation and Registration of Shares, etc.
          --------------------------------------------

     The Company covenants and agrees that all Warrant Shares which are issued
upon the exercise of this Warrant will, upon issuance, be validly issued, fully
paid and nonassessable and free from all taxes, liens, security interests,
charges and other encumbrances with respect to the issue thereof, other than
taxes in respect of any transfer occurring contemporaneously with such issue.
The Company further covenants and agrees that, during the Exercise Period, the
Company will at all times have authorized and reserved, and keep available free
from preemptive rights, a sufficient number of shares of Common Stock to provide
for the exercise of the rights represented by this Warrant and will, at its
expense, upon each such reservation of shares, procure such listing of such
shares of Common Stock (subject to issuance or notice of issuance) as then may
be required on all stock exchanges on which the Common Stock is then listed or
on Nasdaq.

     4.   Representations and Covenants of Warrantholder.
          ----------------------------------------------

     This Warrant has been entered into by the Company in reliance upon the
following representations and covenants of the Warrantholder.

     4.1  Investment Purpose.  The right to acquire the Warrant Shares will be
          ------------------
acquired for investment and not with a view to the sale or distribution of any
part thereof, and the Warrantholder has no present intention of selling or
engaging in any public distribution of the same except pursuant to a
registration or exemption.

     4.2  Private Issue.  The Warrantholder understands (i) that the Warrant
          -------------
Shares issuable upon exercise of this Warrant are not registered under the
Securities Act (or a successor rule thereto) or qualified under applicable state
securities laws on the ground that the issuance contemplated by this Warrant
will be exempt from the registration and qualifications requirements thereof,
and (ii) that the Company's reliance on such exemption is predicated on the
representations set forth in this Section 4.

     4.3  Financial Risk.  The Warrantholder has such knowledge and experience
          --------------
in financial and business matters as to be capable of evaluating the merits and
risks of its investment, and has the ability to bear the economic risks of its
investment.

     4.4  Indefinite Holding Period.  The Warrantholder understands that it may
          -------------------------
be required to hold the Warrant Shares for an indefinite period.  The
Warrantholder also understands that any sale of its rights as the Warrantholder
to purchase the Warrant Shares which might be made by it in reliance upon Rule
144 under the Securities Act may be made only in accordance with the terms and
conditions of that Rule.

                                      -4-
<PAGE>

     4.5  Accredited Investor.  Warrantholder is an "accredited investor" within
          -------------------
the meaning of the Securities and Exchange Rule 501 of Regulation D, as
presently in effect.

     5.   Exchange, Loss or Destruction of Warrant.
          ----------------------------------------

     Upon receipt by the Company of evidence satisfactory to it of the loss,
theft, destruction or mutilation of this Warrant and, in the case of loss, theft
or destruction, of such bond or indemnification as the Company may require, and,
in the case of such mutilation, upon surrender and cancellation of this Warrant,
the Company will execute and deliver a new Warrant of like tenor.  The term
"Warrant" as used in this Agreement shall be deemed to include any Warrants
issued in substitution or exchange for this Warrant.

     6.   Ownership of Warrant.
          --------------------

     The Company may deem and treat the person in whose name this Warrant is
registered as the holder and owner hereof (notwithstanding any notations of
ownership or writing hereon made by anyone other than the Company) for all
purposes and shall not be affected by any notice to the contrary.

     7.   Certain Adjustments.
          -------------------

     7.1  The number of Warrant Shares purchasable upon the exercise of this
Warrant and the Exercise Price shall be subject to adjustment as follows:

     (a)  Stock Dividends.  If at any time prior to the exercise of this Warrant
          ---------------
in full (i) the Company shall fix a record date for the issuance of any stock
dividend payable in shares of Common Stock, or other distribution, or any right
to subscribe for, purchase or otherwise acquire any shares of stock of any class
or any other securities or property, or to receive any other right or (ii) the
number of shares of Common Stock shall have been increased by a subdivision or
split-up of shares of Common Stock, then, on the record date fixed for the
determination of holders of Common Stock entitled to receive such dividend or
immediately after the effective date of subdivision or split-up, as the case may
be, the number of shares of Common Stock to be delivered upon exercise of this
Warrant will be increased so that the Warrantholder will be entitled to receive
the number of shares of Common Stock that such Warrantholder would have owned
immediately following such action had this Warrant been exercised immediately
prior thereto, and the Exercise Price will be adjusted as provided below in
paragraph (f).

     (b)  Combination of Stock.  If at any time prior to the exercise of this
          --------------------
Warrant in full the number of shares of Common Stock outstanding shall have been
decreased by a combination of the outstanding shares of Common Stock, then,
immediately after the effective date of such combination, the number of shares
of Common Stock to be delivered upon exercise of this Warrant will be decreased
so that the Warrantholder thereafter will be entitled to receive the number of
shares of Common Stock that such Warrantholder would have owned immediately
following such action had this Warrant been exercised immediately prior thereto,
and the Exercise Price will be adjusted as provided below in paragraph (f).

     (c)  Reorganization, etc.  If at any time prior to the exercise of this
          -------------------
Warrant in full any capital reorganization of the Company, or any
reclassification of the Common Stock, or any

                                      -5-
<PAGE>

consolidation of the Company with or merger of the Company with or into any
other person or any sale, lease or other transfer of all or substantially all of
the assets of the Company to any other person, shall be effected in such a way
that the holders of Common Stock shall be entitled to receive stock, other
securities or assets (whether such stock, other securities or assets are issued
or distributed by the Company or another person) with respect to or in exchange
for Common Stock, then, upon exercise of this Warrant the Warrantholder shall
have the right to receive the kind and amount of stock, other securities or
assets receivable upon such reorganization, reclassification, consolidation,
merger or sale, lease or other transfer by a holder of the number of shares of
Common Stock that such Warrantholder would have been entitled to receive upon
exercise of this Warrant had this Warrant been exercised immediately before such
reorganization, reclassification, consolidation, merger or sale, lease or other
transfer, subject to adjustments that shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Section 7.

     (d)  Fractional Shares.  No fractional shares of Common Stock or scrip
          -----------------
shall be issued to any Warrantholder in connection with the exercise of this
Warrant.  Instead of any fractional shares of Common Stock that would otherwise
be issuable to such Warrantholder, the Company will pay to such Warrantholder a
cash adjustment in respect of such fractional interest in an amount equal to
that fractional interest of the then current Fair Market Value per share of
Common Stock.

     (e)  Carryover.  Notwithstanding any other provision of this Section 7, no
          ---------
adjustment shall be made to the number of shares of Common Stock to be delivered
to the Warrantholder (or to the Exercise Price) if such adjustment represents
less than 1% of the number of shares to be so delivered, but any lesser
adjustment shall be carried forward and shall be made at the time and together
with the next subsequent adjustment which together with any adjustments so
carried forward shall amount to 1% or more of the number of shares to be so
delivered.

     (f)  Exercise Price Adjustment.  Whenever the number of Warrant Shares
          -------------------------
purchasable upon the exercise of the Warrant is adjusted, as herein provided,
the Exercise Price payable upon the exercise of this Warrant shall be adjusted
by multiplying such Exercise Price immediately prior to such adjustment by a
fraction, of which the numerator shall be the number of Warrant Shares
purchasable upon the exercise of the Warrant immediately prior to such
adjustment, and of which the denominator shall be the number of Warrant Shares
purchasable immediately thereafter.

     (g)  No Duplicate Adjustments.  Notwithstanding anything else to the
          ------------------------
contrary contained herein, in no event will an adjustment be made under the
provisions of this Section 7 to the number of Warrant Shares issuable upon
exercise of this Warrant or the Exercise Price for any event if an adjustment
having substantially the same effect to the Warrantholder as any adjustment that
otherwise would be made under the provisions of this Section 7 is made by the
Company.

     7.2  No Adjustment for Dividends.  Except as provided in Section 7.1, no
          ---------------------------
adjustment in respect of any dividends shall be made during the term of the
Warrant or upon the exercise of this Warrant.

                                      -6-
<PAGE>

     7.3  Notice of Adjustment.  Whenever the number of Warrant Shares or the
          --------------------
Exercise Price of such Warrant Shares is adjusted, as herein provided, the
Company shall promptly mail by first class, postage prepaid, to the
Warrantholder, notice of such adjustment or adjustments and a certificate of the
chief financial officer of the Company setting forth the number of Warrant
Shares and the Exercise Price of such Warrant Shares after such adjustment,
setting forth a brief statement of the facts requiring such adjustment and
setting forth the computation by which such adjustment was made.

     8.   Notices of Corporate Action.
          ---------------------------

     In the event of

     (a)  any taking by the Company of a record of the holders of any class of
securities for the purpose of determining the holders thereof who are entitled

securities or property, or to receive any other right, or

     (b)  any capital reorganization of the Company, any reclassification or
