                           WARRANT TO PURCHASE STOCK

Issuer: CKG Media.com, Inc., a Delaware corporation
Number of Shares: 35,000, subject to adjustment
Class of Stock: Common Stock, $0.001 par value per share
Exercise Price: $0.63 per share, subject to adjustment
Issue Date: October 28, 1999
Expiration Date: October 28, 2006

          THIS WARRANT CERTIFIES THAT, for the agreed upon value of $1.00 and
for other good and valuable consideration, SILICON VALLEY BANK ("Holder") is
entitled to purchase from CKG Media.com, Inc., a Delaware corporation (the
"Company"), Thirty-Five Thousand (35,000) shares of the Company's common stock,
par value $0.001 per share ("Common Stock"), for a purchase price per share of
Sixty Three Cents ($0.63 )(the "Exercise Price").  The number of shares of
Common Stock for which this Warrant is at any time and from time to time
exercisable (the "Shares") and the Exercise Price for the Shares each is subject
to adjustment pursuant to the terms and conditions set forth in this Warrant.

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

          1.1  Method of Exercise.  Holder may exercise this Warrant by
               ------------------
delivering 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 Exercise 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 Exercise 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 1.4.

          1.3  Intentionally Omitted.
               ---------------------
<PAGE>

          1.4  Fair Market Value.  If the Shares are traded in a public market,
               -----------------
the fair market value of the Shares shall be the average closing price of the
Shares (or the closing price of the Company's stock into which the Shares are
convertible) reported for the ten (10) trading days immediately before Holder
delivers its Notice of Exercise to the Company.  If the Shares are not 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 by ten percent (10%) or more, 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.

          1.5  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.

          1.6  Replacement of Warrant.  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, on 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.

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

               1.7.1.    "Acquisition".  For the purpose of this Warrant,
                         -------------
"Acquisition" means any sale, transfer, license, or other disposition of all or
substantially all of the assets 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.
"Acquisition" shall not be deemed to include any issuance of securities by the
Company for financing purposes or in connection with capital raising efforts.

               1.7.2.    Assumption of Warrant.  Upon the closing of any
                         ---------------------
Acquisition, the successor entity shall assume the obligations of this Warrant,
and 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 Exercise Price shall
be adjusted accordingly.

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

                                      -2-
<PAGE>

Common Stock into a greater amount of Common Stock, or, if the Shares are
securities other than Common Stock, subdivides the Shares in a transaction that
increases the amount of Common Stock into which the Shares are convertible, 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.  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 Exercise 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 of
               ---------------------------------
the class or series of securities issuable upon exercise or conversion of this
Warrant are combined or consolidated, by reclassification or otherwise, into a
lesser number of shares, the Exercise Price shall be proportionately increased.

          2.4  No Impairment.  The Company shall not, by amendment of its
               -------------
Certificate of Incorporation or By-laws 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 or the
Registration Rights Agreement (defined below) by the Company, but shall at all
times in good faith assist in carrying out of all the provisions of this Warrant
and in taking all such action as may be necessary or appropriate to protect
Holder's rights under this Warrant against impairment.

          2.5  Fractional Shares.  No fractional Shares shall be issuable upon
               -----------------
exercise or conversion of the Warrant and the number of Shares to be issued
shall be rounded down to the nearest whole Share.  If a fractional share
interest arises upon any exercise or conversion of the Warrant, the Company
shall eliminate such fractional share interest by paying Holder an amount
computed by multiplying the fractional interest by the fair market value of a
full Share.

          2.6  Certificate as to Adjustments.  Upon each adjustment as provided
               -----------------------------
in this Warrant of the number of Shares or the Exercise 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

                                      -3-
<PAGE>

written request, furnish Holder a certificate setting forth the number of Shares
and/or the Exercise Price in effect upon the date thereof and the series of
adjustments leading to such number of Shares and/or Exercise Price.
