     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, but in
no event more than five (5) business days after the date of Company's receipt of
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

                                      -1-


exercise of this Warrant for any cash dividends paid or payable to holders of
record of Series C 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 Series C 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 Series C Stock to be issued to
                Warrantholder under this Section 1.1(b);

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

           A =  the fair market value of one share of the Company's Series C
                Stock (at the date of such calculation);

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

     (c)  Automatic Exercise.  In the event that (a) the Warrantholder has not
          ------------------
exercised this Warrant by 11:59 p.m. on the last day of the Exercise Period and
(b) such exercise would result in the issuance of Warrant Shares to the
Warrantholder based on the formula set forth for a net issue exercise in Section
1.1(b), the Warrantholder shall be deemed to have exercised this Warrant as of
the close of business on such date for all of the Warrant Shares issuable upon
exercise of this Warrant in accordance with the net issue exercise provision set
forth in Section 1.1(b).

     (d)  Fair Market Value. For purposes of Sections 1.1(b) and 1.1(c), the
          -----------------
fair market value of Warrant Shares on the date of calculation shall mean with
respect to each share of Warrant Stock:

          (i)  if the exercise is in connection with an initial public offering
     of the Company's Common Stock, and if the Company's Registration Statement
     relating to such public offering has been declared effective by the
     Securities and Exchange Commission, then the fair market value per share
     shall be the product of (x) the initial

                                      -2-


     "Price to Public" specified in the final prospectus with respect to the
     offering and (y) the number of shares of Common Stock into which each share
     of Warrant Stock is convertible at the date of calculation;

          (ii)   if this Warrant is exercised after, and not in connection with,
     the Company's initial public offering, and if the Company's Common Stock is
     traded on a securities exchange or The Nasdaq Stock Market ("Nasdaq") or
     actively traded over-the-counter:

                 (A)  if the Company's Common Stock is traded on a securities
     exchange or The Nasdaq Stock Market, the fair market value shall be deemed
     to be the product of (x) the average of the closing prices over a twenty
     (20) trading day period ending the trading day before date of exercise and
     (y) the number of shares of Common Stock into which each share of Warrant
     Shares is convertible on such date; or

                 (B)  if the Company's Common Stock is actively traded over-the-
     counter, the fair market value shall be deemed to be the product of (x) the
     average of the closing bid or sales price (whichever is applicable) over
     the twenty (20) trading day period ending the date before the date of
     exercise and (y) the number of shares of Common Stock into which each share
     of Warrant Shares is convertible on such date; or

          (iii)  if neither (i) nor (ii) are applicable, the Market Price of the
     Warrant Shares as of a specified day shall be determined in good faith by
     written resolution of the Board of Directors of the Company.

     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.

     1.3  Information. Upon receipt of a written request from a Warrantholder
          -----------
received before the Company's initial public offering, the Company agrees to
deliver promptly to such Warrantholder a copy of its current financial
statements.

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

     2.1  Restrictions on Transfer. If the Company has not yet completed
          ------------------------
its initial public offering, the Warrant Shares issued upon the exercise of the
Warrant may not be transferred or assigned in whole or in part without the
written consent of the company and 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
restriction set forth in this Section 2.1 will terminate upon the termination of
the Recording and Promotions Agreement.

                                      -3-


     2.2  Restrictive Legends. This Warrant shall (and each Warrant issued
          -------------------
in substitution for this Warrant issued pursuant to Section 5 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."

     Notwithstanding the foregoing, the Warrantholder may require the Company to
issue a stock certificate for Warrant Shares without a legend if (a) 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 (b) 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 Series C 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 Series C Stock
(subject to issuance or notice of issuance) as then may be required on all stock
exchanges on which the Series C 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-


     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 (a) that the Warrant
          -------------
Shares issuable upon exercise of this Warrant are not registered under the 1933
Act 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 (b) 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 1933 Act may be made only in accordance with the terms and
conditions of that Rule.

     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 reasonably 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 entity 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)  Conversion or Redemption of Series C Preferred Stock. Should all of
          ----------------------------------------------------
the Company's Series C Stock be, or if outstanding would be, at any time prior
to the expiration of this Warrant or any portion thereof, redeemed or converted
into shares of the Company's Common Stock in

                                      -5-


accordance with the Company's Amended and Restated Articles of Incorporation,
then this Warrant shall immediately become exercisable for that number of shares
of the Company's Common Stock equal to the number of shares of the Common Stock
that would have been received if this Warrant had been exercised in full and the
Series C Stock received thereupon had been simultaneously converted immediately
prior to such event, and the Exercise Price shall be immediately adjusted to
equal the quotient obtained by dividing (x) the aggregate Exercise Price of the
maximum number of shares of Series C Preferred Stock for which this Warrant was
exercisable immediately prior to such conversion or redemption, by (y) the
number of shares of Common Stock for which this Warrant is exercisable
immediately after such conversion or redemption.

     (b)  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 Series C Stock or (ii) the number of shares of
Series C Stock shall have been increased by a subdivision or split-up of shares
of Series C Stock, then, on the record date fixed for the determination of
holders of Series C 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 Series C 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 Series C 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 (g).

     (c)  Combination of Stock. If at any time prior to the exercise of this
          --------------------
Warrant in full the number of shares of Series C Stock outstanding shall have
been decreased by a combination of the outstanding shares of Series C Stock,
then, immediately after the effective date of such combination, the number of
shares of Series C 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 Series C 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 (g).

     (d)  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 Series C Stock, or any 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 Series C 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 Series C 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 Series C 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.

                                      -6-


     (e)  Fractional Shares. No fractional shares of Series C Stock or scrip
          -----------------
shall be issued to any Warrantholder in connection with the exercise of this
Warrant. Instead of any fractional shares of Series C 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
Series C Stock.

     (f)  Carryover.  Notwithstanding any other provision of this Section 7, no
          ---------
adjustment shall be made to the number of shares of Series C Stock to be
delivered to the Warrantholder (or to the Exercise Price) if such adjustment
represents less than one percent (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 one percent (1%) or more of
the number of shares to be so delivered.

     (g)  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.

     (h)  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.

     7.3  Notice of Adjustment and Warrant Termination.  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.
The Company shall promptly mail by first class, postage prepaid mail to the
Warrantholder, at least thirty (30) days before the end of the Exercise Period,
notice of termination of the Exercise Period.  In such an event, the
Warrantholder will be bound by the provisions of Section 1.1(c).

                                      -7-


     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
to receive any dividend 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

     (b)  any capital reorganization of the Company, any reclassification or
recapitalization of the capital stock of the Company or any Change of Control,
or

     (c)  any voluntary or involuntary dissolution, liquidation or winding-up
of the Company,

the Company will mail to the Warrantholder a notice specifying (i) the date or
expected date on which any such record is to be taken for the purpose of such
dividend, distribution or right and the amount and character of any such
dividend, distribution or right, (ii) the date or expected date on which any
such reorganization, reclassification, recapitalization, Change of Control,
dissolution, liquidation or winding-up is to take place and the time, if any
such time is to be fixed, as of which the holders of record of Series C Stock
(or other securities) shall be entitled to exchange their shares of Series C
Stock (or other securities) for the securities or other property deliverable
upon such reorganization, reclassification, recapitalization, Change of Control,
dissolution, liquidation or winding-up and (iii) that in the event of a Change
of Control, the Warrants are exercisable immediately prior to the consummation
of such Change of Control.  Such notice shall be mailed at least twenty (20)
days prior to the date therein specified, in the case of any date referred to in
the foregoing subdivision (i), and at least twenty (20) days prior to the date
therein specified, in the case of the date referred to in the foregoing
subdivision (ii).
