                                 COMMON STOCK

                         PURCHASE WARRANT CERTIFICATE

                             Dated: June 17, 1999

                       Thirty Thousand (30,000) Warrants

                  To Purchase Up To Thirty Thousand (30,000)

   Shares of Common Stock, $.001 Par Value Per Share, of CKG Media.com, Inc.

     CKG MEDIA.com, Inc., (d/b/a Phase2Media) a Delaware corporation and its
successors, and assigns (the "Company"), hereby issues to SLG Graybar Sublease,
LLC and its permissible successors and assigns (the "Warrant Holder" or
"Holder") these warrants (the "Warrants" or the "Warrant") and certifies that,
for value received, Holder shall, on the terms and subject to the conditions
hereof, be entitled to purchase from the Company, from time to time in
accordance with the provisions hereof, until five (5) years from the date hereof
(the "Expiration Date") up to an aggregate of Thirty Thousand (30,000) shares
(the "Shares" or "Warrant Shares") of the Company's Common Stock, par value .001
per share (the "Securities") at an exercise price equal to $2.50 per share (the
"Per Share Exercise Price").

     1.  Vesting and Exercise of Warrant.  (a) Subject to the provisions of
         -------------------------------
Section 11 below, this Warrant shall vest on the earlier of (i) the delivery of
the "Premises" (as that term is defined in the lease, dated as of June 17, 1999,
between the Company and SLG Graybar
<PAGE>

Sublease, LLC ("SLG") (the "Lease")) by SLG to the Company in accordance with
the terms of the Lease, or (ii) the expiration or waiver of the Company's
cancellation rights pursuant to Insert 16A to the Lease. Upon the vesting of
this Warrant in accordance with the provisions of the immediately preceding
sentence, this Warrant shall be exercisable in whole or in part at any time and
from time to time on or before the Expiration Date.

          (b)  Subsequent to the Vesting of this Warrant in accordance with the
provisions of Section 1(a) above, upon presentation and surrender of this Common
Stock Purchase Warrant Certificate ("Warrant Certificate" or this
"Certificate"), with the attached Form of Election to Purchase duly executed, at
the principal office of the Company at 420 Lexington Avenue, Suite 2102-3, New
York, NY 10170, together with payment to the Company in the amount of the Per
Share Exercise Price multiplied by the number of Warrant Shares being purchased
(the "Aggregate Exercise Price") this Warrant shall be deemed to be exercised.
The Aggregate Exercise Price may be paid at the election of the Holder, as
follows (or any combination of the following): (i) in United States currency by
cash or delivery of a certified check or bank draft payable to the order of the
Company or by wire transfer to the Company, (ii) by cancellation of such number
of the Shares otherwise issuable to the Holder upon such exercise as shall be
specified in such Form of Election to Purchase such that the excess of the
aggregate "Current Market Price" (as hereinbelow defined) of such specified
number of Shares on the date of exercise over the portion of the Per Share
Exercise Price attributable to such Shares shall equal the Per Share Exercise
Price attributable to the Shares to be issued upon such exercise, in which case
such amount shall be deemed to have been paid to the Company and the number of
Shares issuable upon such exercise shall be reduced by such specified number, or
(iii) by surrender to the Company for cancellation certificates representing
Shares of the Company owned by the Holder (properly endorsed for transfer in
blank with signature guaranteed) having a Current Market Price on the date of
exercise equal to the aggregate Per Share Exercise Price with respect to the
number of Shares being exercised.  As used herein, the term "Current Market
Price" shall mean, on any date specified herein, the average of the daily
"Market Price" (as that term is defined hereinbelow) during the ten (10)
consecutive trading days commencing fifteen (15) trading days before such date
of exercise, except that, if on any such date the Shares are not listed or
admitted for trading on any national securities exchange or quoted on the over-
the-counter market, the Current Market Price shall be the Market Price on such
date.  As used herein, the term "Market Price" shall mean, on any date specified
herein, the amount per Share, equal to (a) the last reported sale price of such
Share, regular way, on such date or, in case no such sale takes place on such
date, the average of the closing bid and asked prices thereof, regular way, on
such date, in either case as officially reported on the principal national
securities exchange on which such Shares are then listed or admitted for
trading, or (b) if such Shares are not then listed or admitted for trading on
any national securities exchange but is designated as a National Market System
security by The Nasdaq Stock Market, the last reported trading price per Share
on such date, or (c) if there shall have been no trading on such date or if the
Shares are not designated as a National Market System security by The Nasdaq
Stock Market but has been designated as a Smallcap security by The Nasdaq Stock
Market or is quoted on The Nasdaq Stock Market's (or any successor market's)
over-the-counter market or on its electronic bulletin

                                       2
<PAGE>

board, the average of the closing bid and asked prices per Share on such date as
shown by The Nasdaq Stock Market's (or any successor market's) automated
quotation system, over-the-counter market or electronic bulletin board, as the
case may be, or (d) if such Shares are not then listed or admitted for trading
on any national exchange or quoted on The Nasdaq Stock Market, over-the-counter
market, or electronic bulletin board, the fair value thereof (as of a date which
is within twenty (20) days of the date as of which the determination is to be
made) determined in good faith by the Board of Directors of the Company;
provided, however that in the event that the Holder in good faith disagrees with
--------  -------
the determination made by the Company's Board of Directors, and the Holder and
the Company cannot agree on an appropriate value with respect to the Shares
within five (5) days thereafter, then the determination of the appropriate value
of the Shares shall be made by an independent investment banking firm agreed
upon by the Company and Holder. In the event that the Company and Holder cannot
agree upon an independent investment banking firm, then each of the Company and
Holder shall choose an independent investment banking firm and the two
independent investment banking firms shall designate a third independent
investment banking firm that shall make such determination. Any independent
investment banking firm shall take all relevant factors into account in making
such determination, including but not limited to appropriate discounts for
minority interests and lack of liquidity. The Company and the Holder shall share
equally all costs and expenses of any nature whatsoever in connection with
obtaining such valuation of the Shares, including but not limited to any fees
and disbursements of any independent investment banking firm contacted or
retained hereunder. Upon receipt of the Aggregate Exercise Price, the Company,
or the Company's transfer agent, as the case may be, shall deliver to the
Warrant Holder hereof, certificates of the Securities which in the aggregate
represent the number of Warrant Shares being purchased. All or less than all of
the Warrants represented by this Certificate may be exercised and, in case of
the exercise of less than all, the Company, upon surrender hereof, will deliver
to the Warrant Holder a new Warrant Certificate or Certificates of like tenor
and dated the date hereof entitling said Warrant Holder to purchase the number
of Warrant Shares represented by this Certificate which have not been exercised.

     2.   Exchange and Transfer.  Upon presentation and surrender to the Company
          ---------------------
of this Certificate at any time prior to the exercise hereof, this certificate
may be exchanged, alone or with other Certificates of like tenor registered in
the name of the same Warrant Holder, for another Certificate or Certificates
(collectively, the "New Certificate(s)") of like tenor in the name of such
Warrant Holder. The New Certificate(s) shall be exercisable for the aggregate
number of Warrant Shares as the Certificate or Certificates surrendered. All
references herein to Certificate or Certificates shall be deemed to include any
New Certificate(s).

     2.1  When Exercise Effective.   Each exercise of this Warrant shall be
          -----------------------
deemed to have been effected immediately prior to the close of business on the
"Business Day" (as hereinbelow defined) on which the Certificate, Form of
Election to Purchase Shares and the Aggregate Exercise Price (if the Warrant is
being exercised in accordance with the provisions of Section 1(b)(i) and/or
Section 1(b)(iii) above) shall have been received by the Company as provided in
Section 2.  At such time, the Holder or Holders in whose name or names any
certificate or

                                       3
<PAGE>

certificates for Shares shall be issuable upon the exercise of the Warrant shall
be deemed to have become the holder or holders of record thereof for all
purposes. As used herein, the term "Business Day" shall mean any day other than
Saturday or Sunday or a day on which commercial banking institutions in the City
of New York are authorized by law to be closed. In the event that the Expiration
Date is not a Business Day, the Expiration Date shall automatically be deemed to
be the next succeeding Business Day immediately subsequent to such date.

     2.2  Delivery of Stock Certificates, etc.; Charges, Taxes and Expenses.  As
          -----------------------------------------------------------------
soon as practicable after each exercise of this Warrant, in whole or in part,
and in any event within five (5) Business Days thereafter, the Company shall
cause to be issued in the name of and delivered to the Holder hereof, a
certificate or certificates for the number of Shares (or other securities as the
case may be) to which the Holder shall be entitled upon such exercise plus, in
lieu of issuance of any fractional share to which the Holder would otherwise be
entitled, if any, a check for the amount of cash equal to the same fraction
multiplied by the Current Market Price per share on the date of exercise.

     3.   Rights and Obligations of Warrant Holder of this Certificate.  The
          ------------------------------------------------------------
Holder of this Certificate shall not, by virtue hereof, be entitled to any
rights of a stockholder in the Company, either at law or in equity; provided,
however, that in the event any certificate representing Shares or other
securities is issued to the Holder hereof upon exercise of some or all of the
Warrants, such Holder shall, for all purposes, be deemed to have become the
Holder of record of such Shares in accordance with Section 2.1 above. The rights
of the Holder of this Certificate are limited to those expressed herein and the
Holder of this Certificate, by his or its acceptance hereof, consents to and
agrees to be bound by and to comply with all the provisions of this Certificate,
including without limitation all the obligations imposed upon the Warrant Holder
hereof by Section 6. In addition, the Warrant Holder of this Certificate, by
accepting the same, agrees that the Company may deem and treat the person in
whose name this Certificate is registered on the books of the Company as the
absolute, true and lawful owner for all purposes whatsoever, and the Company
shall not be affected by any notice to the contrary.

     4.   Shares.  (a)  The Company covenants and agrees that all Shares
          ------
issuable upon the exercise of this Warrant Certificate will, upon delivery, be
duly and validly authorized and issued, fully-paid and non-assessable, and free
from all stamp-taxes, liens, and charges with respect to the purchase thereof.

          (b)  The Company covenants and agrees that it will at all times
reserve and keep available an authorized number of Shares and other applicable
Securities sufficient to permit the exercise in full of all outstanding options,
warrants and rights, including the Warrants.

     5.   Legended Certificates.  All certificates representing Shares issuable
          ---------------------
upon the exercise of Warrants shall bear restrictive legends substantially in
the form of the bold face language appearing on Page 1 of this Warrant
Certificate to the effect that the Shares represented by such certificate have
not been registered under the Securities Act of 1933, as amended and the

                                       4
<PAGE>

rules and regulations promulgated thereunder (the "Securities Act"), or
qualified under any state securities laws and the Shares may not be sold or
transferred in the absence of such registration and qualification or an
exemption thereof.

     6.   Disposition of Warrants or Shares.  The Holder of this Warrant
          ---------------------------------
Certificate, by his acceptance thereof, agrees that (a) no public distribution
of Warrants or Shares will be made in violation of the provisions of the
Securities Act, and (b) during such period as delivery of a prospectus with
respect to Warrants or Shares is required by the Securities Act, no public
distribution of Warrants or Shares will be made in a manner or on terms
different from those set forth in, or without delivery of, a prospectus then
meeting the requirements of Section 10 of the Securities Act and in compliance
with all applicable state securities laws. The Holder of this Certificate and
each transferee hereof further agrees that if any distribution of any of the
Warrants or Shares is proposed to be made by them otherwise than by delivery of
a prospectus meeting the requirements of Section 10 of the Securities Act, such
action shall be taken only after receipt by the Company of an opinion of
Company's counsel, to the effect that the proposed distribution will not be in
violation of the Securities Act or of applicable state law. Furthermore, it
shall be a condition to the transfer of the Warrants that any transferee thereof
deliver to the Company his or its written agreement to accept and be bound by
all of the terms and conditions contained in this Warrant Certificate.

     7.   "Piggyback" Registration.
          ------------------------

          (a)  At any time after the effective date of a registration statement
relating to the initial public offering of the Company's securities under
Section 5 of the Securities Act, the Company shall thereafter determine to
proceed with the actual preparation and filing of a registration statement under
the Securities Act in connection with the proposed offer and sale of any of its
securities by the Company solely on behalf of any of the Company's security
holders and not for the Company's own account (other than a registration
statement on Form S-4, S-8 or other successor or comparable form), the Company
shall give written notice of its determination (the "Piggyback Notice") to all
Holders of "Registrable Securities" (as that term is hereinafter defined) at
least thirty (30) days prior to filing such registration statement.  As used
herein, the term Registrable Securities shall mean all Warrant Shares that have
actually been issued or that are issuable upon the exercise of this Warrant.
Upon the written request from the holder of any Registrable Securities within
twenty (20) days after the giving of the Piggyback Notice, the Company shall,
except as herein provided, cause such Registrable Securities to be included in
such registration statement, all to the extent required to permit the sale or
other disposition by the prospective seller or sellers of the Registrable
Securities to be so registered; provided, however, that nothing herein shall
                                --------  -------
prevent the Company from, at any time, abandoning or delaying any such Company
initiated registration.  If any registration pursuant to this Section 7 shall be
underwritten in whole or in part, the Company may require that the Registrable
Securities requested for inclusion pursuant to this Section 7 be included in the
underwriting on the same terms and conditions as the securities otherwise being
sold through the underwriter(s).  In the event that in the good faith judgment
of a managing underwriter of such public offering that the

                                       5
<PAGE>

inclusion of all of the Registrable Securities originally covered by a request
for registration would materially adversely affect the successful marketing of
the securities offered by the Company, the number of shares of Registrable
Securities otherwise to be included in the underwritten public offering may be
eliminated or reduced pro rata among all selling security holders requesting
such registration (including any selling security holder not subject to this
agreement) as required by the managing underwriter. To the extent only a portion
of the Registrable Securities are included in the underwritten public offering,
those Registerable Securities that are excluded from the underwritten public
offering shall be withheld from the market by the holders thereof for a period,
not to exceed 270 days, which the managing underwriter reasonably determines is
necessary to effect the underwritten public offering.

     There shall not be any limit to the number of piggyback registrations may
be requested by the holders of Registrable Securities.

          (b)  (i)  Each holder of Registrable Securities agrees, by acquisition
of such Registrable Securities, if timely requested in writing by the managing
underwriter in an underwritten public offering, not to make any short sale of,
loan, grant any option for the purchase of or effect any public sale or
distribution, including a sale pursuant to Rule 144 (or any successor provision
having similar effect) under the Securities Act of any registrable securities or
any other equity security of the Company (or any security convertible into or
exchangeable or exercisable for any equity security of the Company) (except as
part of such underwritten registration), during the nine business days (as such
term is used in Regulation M under the Securities Exchange Act of 1934, as
amended) prior to, and during the time period reasonably requested by the
managing underwriter not to exceed 90 days, beginning on the effective date of
the applicable registration statement.

               (ii) The Company agrees that (i) if timely requested in writing
by the managing underwriter in an underwritten public offering, not to make any
short sale of, loan, grant any option for the purchase of or effect any public
sale or distribution of any of the Company's equity securities (or any security
convertible into or exchangeable or exercisable for any of the Company's equity
securities) during the nine business days (as such term is used in Regulation M
under the Securities Exchange Act) prior to, and during the time period
reasonably requested by the managing underwriter not to exceed 90 days,
beginning on the effective date of the applicable registration statement (except
as part of such underwritten registration pursuant to registrations on Form S-4
or S-8 or any successor form to such forms), and (ii) it will cause each holder
of equity securities (or any security convertible into or exchangeable or
exercisable for any of its equity securities) of the Company purchased from the
Company at any time after the date of this Agreement (other than in a registered
public offering) to so agree.

          (c)  Whenever the Company is required by the provisions of Section 7
hereof to effect the registration of Registrable Securities under the Securities
Act, the Company shall:

               (i)  prepare and file with the Securities and Exchange Commission
(the

                                       6
<PAGE>

"SEC") a registration statement with respect to the Registrable Securities, and
use its best efforts to cause such registration statement to become and remain
effective as promptly as practicable for such period as may be reasonably
necessary to effect the sale of such Registrable Securities, not to exceed nine
(9) months;

               (ii)  prepare and file with the SEC such amendments to such
registration statement and supplements to the prospectus contained therein as
may be necessary to keep such registration statement effective for such period
as may be reasonably necessary to effect the sale of the Registrable Securities,
not to exceed nine (9) months;

               (iii) furnish to any Holder participating in such registration (a
"Participating Holder") such reasonable number of copies of the registration
statement, preliminary prospectus, final prospectus and such other documents as
such Participating Holder may reasonably request in order to facilitate the
public offering of the Participating Holder's securities;

               (iv)  use its best efforts to register or qualify the Registrable
Securities covered by such registration statement under such state securities or
blue sky laws of such jurisdiction, except that the Company shall not for any
purpose be required to execute a general consent to service of process or to
qualify to do business as a foreign corporation in any jurisdiction wherein it
is not so qualified;

               (v)   notify the Participating Holders, promptly after it shall
receive notice thereof, of the time when such registration statement or a
supplement to any prospectus forming a part of such registration statement has
become effective;

               (vi)  prepare and file with the SEC, any amendments or
supplements to such registration statement or prospectus which are required
under the Securities Act or the rules and regulations thereunder in connection
with the distribution of the Warrant Shares by the Participating Holders;

               (vii) prepare and promptly file with the SEC and promptly notify
the Participating Holders of the filing of such amendment or supplement to such
registration statement or prospectus as may be necessary to correct any
statements or omissions if, at the time when a prospectus relating to such
Registrable Securities is required to be delivered under the Securities Act, any
event shall have occurred as the result of which any such prospectus or any
other prospectuses then in effect would include an untrue statement of a
material fact or omit to state any material fact necessary to make the
statements therein, in the light of the circumstances in which whey were made,
not misleading;

          (d)  advise the Participating Holders, promptly after it shall receive
notice or obtain knowledge thereof, of the issuance of any stop order by the
Division of Enforcement of the SEC suspending the effectiveness of such
registration statement or the initiation or

                                       7
<PAGE>

threatening of any proceeding for that purpose and promptly use its best efforts
to prevent the issuance of any stop order or to obtain its withdrawal if such
stop order should be issued; and

          (e)  indemnify and hold harmless each Participating Holder against any
and all losses, claims, damages or liabilities to which such Participating
Holder shall become subject, under the Securities Act or otherwise, that arise
out of or are based upon any untrue statement or alleged untrue statement of any
material fact contained in the registration statement or prospectus thereunder
or any amendment or supplement thereto, or any related preliminary prospectus,
or arise out of or are based upon any omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading; provided, however, that no such
                                   --------  -------
indemnification shall be available to any Participating Holder with respect to,
and to the extent there is liability attributable to, written information
provided by a Participating Holder to the Company for use in such registration
statement or prospectus.

          (f)  All fees, costs and expenses of and incidental to the
registration of Registrable Securities (as specified in this Section 7(f)) in
connection with any registration hereunder, shall be borne by the Company if
registration is requested pursuant to Section 7 hereof; provided, however, that
                                                        --------  -------
Participating Holders shall bear their pro rata share of the underwriting
discount and commissions and transfer taxes. The costs and expense of
registration to be borne by the Company shall include all registration, filing
fees, printing expenses, fees and disbursements of counsel and accountants for
the Company, and all legal fees and disbursements and other expenses of
complying with state securities or blue sky laws of any jurisdiction in which
the securities to be offered are to be registered and qualified. Any other
expenses actually incurred by the Participating Holders (including but not
limited to any fees and disbursements of counsel, accountants or other advisors
retained by Participating Holders) not included above shall be borne in all
cases by the Participating Holders.

     8.   Anti-Dilution.  If the Company at any time or from time to time while
          -------------
this Warrant Certificate is outstanding shall declare or pay, without
consideration, any dividend on the Shares payable in Shares, or shall effect a
subdivision of the outstanding Shares into a greater number of Shares (by stock
split, reclassification or otherwise other than by the payment of a dividend in
Shares or in any right to acquire Shares), or if the outstanding Shares shall be
combined or consolidated, by reclassification or otherwise, into a lesser number
of Shares, then the number of Shares issuable upon the exercise of this Warrant
Certificate and the Per Share Exercise Price shall be appropriately adjusted
such that immediately after the occurrence of any such event, the proportionate
number of Shares issuable immediately prior to the occurrence of such event
shall be the number of Shares issuable subsequent to the occurrence of such
event.

     9.   Consolidation, Merger.  In the event that the Company, after the date
          ---------------------
hereof (a) shall consolidate with or merge into any other person or entity and
shall not be the continuing or surviving corporation of such consolidation or
merger, or (b) shall permit any other person or entity to consolidate with or
merge into the Company and the Company shall be the continuing or surviving
person or entity but, in connection with such consolidation or merger, the
Shares or

                                       8
<PAGE>

other securities shall be changed into or exchanged for stock or other
securities of any other person or entity or cash or any other property, then,
and in the case of each such transaction, proper provision shall be made so
that, upon the basis and the terms and in the manner provided in this Warrant,
the Holders of this Warrant, upon the exercise hereof at any time after the
consummation of such transaction, shall be entitled to receive (at the aggregate
Per Share Exercise Price in effect at the time of such consummation for all
Shares or other securities issuable upon such exercise immediately prior to such
consummation), in lieu of the Shares or other securities issuable upon such
exercise prior to such consummation, the securities, cash or other property to
which such Holder would actually have been entitled as a stockholder upon such
consummation if such Holder had exercised this Warrant immediately prior
thereto, subject to adjustments (subsequent to such consummation) as nearly
equivalent as possible to the adjustments provided for elsewhere in this Warrant
Certificate.

     10.  Notices.   Except as otherwise specified herein to the contrary, all
          -------
notices, requests, demands and other communications required or desired to be
given hereunder shall only be effective if given in writing by hand, by
certified or registered mail, return receipt requested, postage prepaid, or by

THIS WARRANT AND THE SHARES ISSUABLE HEREUNDER HAVE NOT BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, PLEDGED, OR
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

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.
