OTHERWISE TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION THEREOF UNDER SUCH ACT
OR PURSUANT TO RULE 144 OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE
CORPORATION AND ITS COUNSEL THAT SUCH REGISTRATION IS NOT REQUIRED.

                           WARRANT TO PURCHASE STOCK

Corporation:             Replay Networks, Inc., a California corporation
Number of Shares:        11,000 (subject to Section 1.9)
Class of Stock:          Common (subject to Section 1.9)
Initial Exercise Price:  $7.50 per share (subject to Section 1.9)
Issue Date:              May 31, 1999
Expiration Date:         May 31, 2004 (Subject to Article 4.1)

     THIS WARRANT CERTIFIES THAT, in consideration of the payment of $1.00 and
for other good and valuable consideration, IMPERIAL BANCORP or registered
assignee ("Holder") is entitled to purchase the number of fully paid and
nonassessable shares of the class of securities (the "Shares") of the
corporation (the "Company") at the initial exercise price per Share (the
"Warrant Price") all as set forth above and as adjusted pursuant to Article 2 of
this Warrant, subject to the provisions and upon the terms and conditions set
forth in this Warrant.

ARTICLE 1. EXERCISE
           --------

     1.1  Method of Exercise. Holder may exercise this Warrant by delivering
          ------------------
this Warrant and a duly executed Notice of Exercise in substantially the form
attached as Appendix 1 to the principal office of the Company. Unless Holder is
exercising the conversion right set forth in Section 1.2, Holder shall also
deliver to the Company a check for the aggregate Warrant Price for the Shares
being purchased.

     1.2  Conversion Right. In lieu of exercising this Warrant as specified in
          ----------------
Section 1.1, Holder may from time to time convert this Warrant, in whole or in
part, into a number of Shares determined by dividing (a) the aggregate fair
market value of the Shares or other securities otherwise issuable upon exercise
of this Warrant minus the aggregate Warrant Price of such Shares by (b) the fair
market value of one Share. The fair market value of the Shares shall be
determined pursuant to Section 1.5.

     1.3  Omitted.
          -------

     1.4  Omitted.
          -------


     1.5  Fair Market Value. If the Shares are traded regularly in a public
          -----------------
market, the fair market value of the Shares shall be the closing price of the
Shares (or the closing price of the Company's stock into which the Shares are
convertible) reported for the business day immediately before Holder delivers
its Notice of Exercise to the Company. If the Shares are not regularly traded in
a public market, the Board of Directors of the Company shall determine fair
market value in its reasonable good faith judgment. The foregoing
notwithstanding, if Holder advises the Board of Directors in writing that Holder
disagrees with such determination, then the Company and Holder shall promptly
agree upon a reputable investment banking firm to undertake such valuation. If
the valuation of such investment banking firm is greater than that determined by
the Board of Directors, then all fees and expenses of such investment banking
firm shall be paid by the Company. In all other circumstances, such fees and
expenses shall be paid by Holder.

     1.6  Delivery of Certificate and New Warrant. Promptly after Holder
          ---------------------------------------
exercises or converts this Warrant, the Company shall deliver to Holder
certificates for the Shares acquired and, if this Warrant has not been fully
exercised or converted and has not expired, a new Warrant representing the
Shares not so acquired.

     1.7  Replacement of Warrants. On receipt of evidence reasonably
          -----------------------
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery of an
indemnity agreement reasonably satisfactory in form and amount to the Company
or, in the case of mutilation, or surrender and cancellation of this Warrant,
the Company at its expense shall execute and deliver, in lieu of this Warrant, a
new warrant of like tenor.

     1.8  Repurchase on Sale, Merger, or Consolidation of the Company.
          -----------------------------------------------------------

          1.8.1.  "Acquisition". For the purpose of this Warrant, "Acquisition"
                  -------------
means any sale, license, or other disposition of all or substantially all of the
assets (including intellectual property) of the Company, or any reorganization,
consolidation, or merger of the Company where the holders of the Company's
securities before the transaction beneficially own less than 50% of the
outstanding voting securities of the surviving entity after the transaction.

          1.8.2.  Assumption of Warrant. If upon the closing of any Acquisition
                  ---------------------
the successor entity assumes the obligations of this Warrant, then this Warrant
shall be exercisable for the same securities, cash, and property as would be
payable for the Shares issuable upon exercise of the unexercised portion of this
Warrant as if such Shares were outstanding on the record date for the
Acquisition and subsequent closing. The Warrant Price shall be adjusted
accordingly. The Company shall use reasonable efforts to cause the surviving
corporation to assume the obligations of this Warrant.

          1.8.3.  Nonassumption. If upon the closing of any Acquisition the
                  -------------
successor entity does not assume the obligations of this Warrant and Holder has
not otherwise exercised this Warrant in full, then the unexercised portion of
this Warrant shall be deemed to have been automatically converted pursuant to
Section 1.2 and thereafter Holder shall participate in the Acquisition on the
same terms as other holders of the same class of securities of the Company.


     1.9  Adjustment in Underlying Stock Price and Exercise Price. If on or
          -------------------------------------------------------
before July 31, 1999, the Company sells and issues to any investors, preferred
stock with aggregate gross proceeds to the Company of at least $8,000,000, this
Warrant shall concurrent with the issuance of such shares of preferred stock
automatically be adjusted to instead be exercisable for shares of the same
series and class and bearing the same rights, preferences, and privileges, of
such shares of stock, with the Warrant Price hereunder adjusted to equal the per
share purchase price of such stock, and the number of such shares subject to
this Warrant adjusted to equal (i) Fifty Thousand Dollars ($50,000), divided by
(ii) such modified per share Warrant Price.

ARTICLE 2. ADJUSTMENTS TO THE SHARES.
           -------------------------

     2.1  Stock Dividends, Splits, Etc. If the Company declares or pays a
          ----------------------------
dividend on its common stock payable in common stock, or other securities or
subdivides the outstanding common stock into a greater amount of common stock,
then upon exercise of this Warrant, for each Share acquired, Holder shall
receive, without cost to Holder, the total number and kind of securities to
which Holder would have been entitled had Holder owned the Shares of record as
of the date the dividend or subdivision occurred.

     2.2  Reclassification, Exchange or Substitution. Upon any reclassification,
          ------------------------------------------
exchange, substitution, or other event that results in a change of the number
and/or class of the securities issuable upon exercise or conversion of this
Warrant, Holder shall be entitled to receive, upon exercise or conversion of
this Warrant, the number and kind of securities and property that Holder would
have received for the Shares if this Warrant had been exercised immediately
before such reclassification, exchange, substitution, or other event. Such an
event shall include any automatic conversion of the outstanding or issuable
securities of the Company of the same class or series as the Shares to common
stock purser to the terms of the Company's Articles of Incorporation upon the
closing of a registered public offering of the Company's common stock. The
Company or its successor shall promptly issue to Holder a new Warrant for such
new securities or other property. The new Warrant shall provide for adjustments
which shall be as nearly equivalent as may be practicable to the adjustments
provided for in this Article 2 including, without limitation, adjustments to the
Warrant Price and to the number of securities or property issuable upon exercise
of the new Warrant. The provisions of this Section 2.2 shall similarly apply to
successive reclassifications, exchanges, substitutions, or other events.

     2.3  Adjustments for Combinations, Etc. If the outstanding Shares are
          ---------------------------------
combined or consolidated, by reclassification or otherwise, into a lesser number
of shares, the Warrant Price shall be proportionately increased and the number
of shares purchasable upon exorcise of this warrant shall be proportionately
decreased.

     2.4  Adjustments for Diluting Issuances. The Warrant Price and the number
          ----------------------------------
of Shares issuable upon exercise of this Warrant shall be subject to adjustment,
from time to time, in the manner set forth on Exhibit B, in the event (i) the
Warrant is adjusted to be exercisable for preferred stock as specified in
Section 1.9 above in combination with (ii) the occurrence of Diluting Issuances
(as defined on Exhibit B).


     2.5  No Impairment. The Company shall not, by amendment of its Articles of
          -------------
Incorporation or through a reorganization, transfer of assets, consolidation,
merger, dissolution, issue, or sale of securities or any other voluntary action,
avoid or seek to avoid the observance or performance of any of the terms to be
observed or performed under this Warrant by the Company, but shall at all times
in good faith assist in carrying out all the provisions of this Article 2 and in
taking all such action as may be necessary or appropriate to protect Holder's
rights under this Article against impairment. If the Company takes any action
affecting the Shares or its common stock other than as described above that
adversely affects Holder's rights under this Warrant, the Warrant Price shall be
adjusted downward and the number of Shares issuable upon exercise of this
Warrant shall be adjusted upward in such a manner that the aggregate Warrant
Price of this Warrant is unchanged.

     2.6  Certificate as to Adjustments. Upon each adjustment of the Warrant
          -----------------------------
Price, the Company at its expense shall promptly compute such adjustment, and
furnish Holder with a certificate of its Chief Financial Officer setting forth
such adjustment and the facts upon which such adjustment is based. The Company
shall, upon written request, furnish Holder a certificate setting forth the
Warrant Price in effect upon the date thereof and the series of adjustments
leading to such Warrant Price.

ARTICLE 3. REPRESENTATIONS AND COVENANTS OF THE COMPANY.
           --------------------------------------------

     3.1  Representations and Warranties. The Company hereby represents and
          ------------------------------
