hereinafter set forth. Capitalized terms used in this Warrant and not otherwise
defined herein shall have the respective meanings specified in Section 7 hereof.

     1.   Term.  The right to subscribe for and purchase shares of Warrant Stock
          ----
represented hereby shall commence on the date of issuance of this Warrant and
shall expire two (2) years from the date of issuance, at 5:00 p.m., eastern

     2.   Method of Exercise Payment; Issuance of New Warrant; Transfer and
          -----------------------------------------------------------------
Exchange.
--------

     (a)  Time of Exercise.  The purchase rights represented by this Warrant may
          ----------------
be exercised in whole or in part at any time and from time to time during the
Term.

     (b)  Method of Exercise.  The Holder hereof may exercise this Warrant, in
          ------------------
whole or in part, by the surrender of this Warrant (with the exercise form
attached hereto duly executed) at the principal office of the Issuer, and by the
payment to the Issuer of an amount of consideration therefor equal to the
Warrant Price in effect on the date of such exercise multiplied by the number of
shares of Warrant Stock with respect to which this Warrant is then being
exercised, payable at such Holder's election (i) by certified or official bank
check or (ii) by surrender to the Issuer for cancellation of a portion of this
Warrant representing that number of unissued shares of Warrant Stock which is
equal to the quotient obtained by dividing (A) the product obtained by
multiplying the Warrant Price by the number of shares of Warrant Stock being
purchased upon such exercise by (B) the difference obtained by subtracting the
Warrant Price from the Per Share Market Value as of the date of such exercise,
or (iii) by a combination of the foregoing methods of payment selected by the
Holder of this Warrant.  In any case where the consideration payable upon such
exercise is being paid in whole or in part pursuant to the provisions of clause
(ii) of this subsection (b), such exercise shall be accompanied by written
notice from the Holder of this Warrant specifying the manner of payment thereof
and containing a calculation showing the number of shares of Warrant Stock with
respect to which rights are being surrendered thereunder and the net number of
shares of Common Stock to be issued after giving effect to such surrender.

     (c)  Issuance of Stock Certificates.  In the event of any exercise of the
          ------------------------------
rights represented by this Warrant in accordance with and subject to the terms
and conditions hereof, (i) certificates for the shares of Warrant Stock so
purchased shall be dated the date of such exercise and delivered to the Holder
hereof within a reasonable time, not exceeding three (3) Trading Days after such
exercise, and the Holder hereof shall be deemed for all purposes to be the
Holder of the shares of Warrant Stock so purchased as of the date of such
exercise, and (ii) unless this Warrant has expired, a new Warrant representing
the number of shares of Warrant Stock, if any, with respect to which this
Warrant shall not then have been exercised (less any amount thereof which shall
have been canceled in payment or partial payment of the Warrant Price as

                                      -2-
<PAGE>

hereinabove provided) shall also be issued to the Holder hereof at the Issuer's
expense within such time.

     (d)  Transferability of Warrant.  Subject to Section 2(e), this Warrant may
          --------------------------
be transferred by a Holder without the consent of the Issuer.  If transferred
pursuant to this subsection and subject to the provisions of subsection (e) of
this Section 2, this Warrant may be transferred on the books of the Issuer by
the Holder hereof in person or by duly authorized attorney, upon surrender of
this Warrant at the principal office of the Issuer, properly endorsed (by the
Holder executing an assignment in the form attached hereto) and upon payment of
any necessary transfer tax imposed upon such transfer.  This Warrant is
exchangeable at the principal office of the Issuer for Warrants for the purchase
of the same aggregate number of shares of Warrant Stock, each new Warrant to
represent the right to purchase such number of shares of Warrant Stock as the
Holder hereof shall designate at the time of such exchange.  All Warrants issued
on transfers or exchanges shall be dated the Original Issue Date and shall be
identical with this Warrant except as to the number of shares of Warrant Stock
issuable pursuant hereto.

     (e)  Compliance with Securities Laws.
          --------------------------------

          (i)  The Holder of this Warrant, by acceptance hereof, acknowledges
     that this Warrant or the shares of Warrant Stock to be issued upon exercise
     hereof are being acquired solely for the Holder's own account and not as a
     nominee for any other party, and for investment, and that the Holder will
     not offer, sell or otherwise dispose of this Warrant or any shares of
     Warrant Stock to be issued upon exercise hereof except pursuant to an
     effective registration statement, or an exemption from registration, under
     the Securities Act and any applicable state securities laws.

          (ii) Except as provided in paragraph (iii) below, this Warrant and all
     certificates representing shares of Warrant Stock issued upon exercise
     hereof shall be stamped or imprinted with a legend in substantially the
     following form:

     THIS WARRANT AND THE SHARES OF COMMON STOCK ISSUABLE UPON EXERCISE HEREOF
     HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
     "SECURITIES ACT"), OR ANY STATE SECURITIES LAWS AND MAY NOT BE EXERCISED BY
     OR ON BEHALF OF ANY U.S. PERSON, OR SOLD, TRANSFERRED, ASSIGNED, PLEDGED OR
     HYPOTHECATED OR OTHERWISE DISPOSED OF UNLESS REGISTERED UNDER THAT ACT AND
     UNDER APPLICABLE STATE SECURITIES LAWS OR BID.COM INTERNATIONAL INC. (THE
     "COMPANY") SHALL HAVE RECEIVED AN OPINION, IN FORM, SCOPE AND SUBSTANCE
     REASONABLY ACCEPTABLE TO THE COMPANY, OF COUNSEL WHO IS REASONABLY
     ACCEPTABLE TO THE COMPANY THAT REGISTRATION OF SUCH SECURITIES UNDER THAT
     ACT AND UNDER THE PROVISIONS OF APPLICABLE FEDERAL AND STATE SECURITIES
     LAWS IS NOT REQUIRED.

     THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN QUALIFIED FOR DISTRIBUTION
     AND SALE WITHIN THE PROVINCE OF ONTARIO, CANADA AND MAY NOT BE DISTRIBUTED
     OR SOLD IN SUCH PROVINCE OR TO A

                                      -3-
<PAGE>

     RESIDENT THEREOF FOR A PERIOD OF NINETY (90) DAYS FOLLOWING THE DATE OF
     ISSUANCE OF THIS CERTIFICATE EXCEPT (A) PURSUANT TO A PROSPECTUS FOR WHICH
     A RECEIPT HAS BEEN ISSUED BY THE ONTARIO SECURITIES COMMISSION OR (B)
     PURSUANT TO AN AVAILABLE EXEMPTION FROM SUCH PROSPECTUS REQUIREMENT.

          (iii)  The restrictions imposed by this subsection (e) upon the
     transfer of this Warrant or the shares of Warrant Stock to be purchased
     upon exercise hereof shall terminate (A) when such securities shall have
     been resold pursuant to being effectively registered under the Securities
     Act or (B) upon the Issuer's receipt of an opinion of counsel to the
     Issuer, in form and substance reasonably satisfactory to the Issuer,
     addressed to the Issuer to the effect that such restrictions are no longer
     required to ensure compliance with the Securities Act and state securities
     laws.  Whenever such restrictions shall cease and terminate as to any such
     securities, the Holder (unless the Holder is then an Affiliate of the
     Company) thereof shall be entitled to receive from the Issuer (or its
     transfer agent and registrar), without expense (other than applicable
     transfer taxes, if any), new Warrants (or, in the case of shares of Warrant
     Stock, new stock certificates) of like tenor not bearing the applicable
     legend required by paragraph (ii) above relating to the Securities Act and
     applicable state securities laws.

     3.   Stock Fully Paid; Reservation and Listing of Shares; Covenants.
          --------------------------------------------------------------

     (a)  Stock Fully Paid.  The Issuer represents, warrants, covenants and
          ----------------
agrees that all shares of Warrant Stock which may be issued upon the exercise of
this Warrant or otherwise hereunder will, upon issuance in accordance with the
terms of the Warrant, be duly authorized, validly issued, fully paid and non-
assessable and free from all taxes and liens, security interest, charges and
encumbrances of any nature whatsoever created by or through the Issuer.  The
Issuer further represents, warrants, covenants and agrees that during the period
within which this Warrant may be exercised, the Issuer will at all times have
authorized and reserved for the purpose of the issue upon exercise of this
Warrant a sufficient number of shares of Common Stock to provide for the
exercise of this Warrant.

     (b)  Reservation.  If any shares of Common Stock required to be reserved
          -----------
for issuance upon exercise of this Warrant or as otherwise provided hereunder
require registration or qualification with any governmental authority under any
federal or state law before such shares may be so issued, the Issuer will in
good faith use its best efforts as expeditiously as possible at its expense to
cause such shares to be duly registered or qualified.  If the Issuer shall list
any shares of Common Stock on any securities exchange or market it will, at its
expense, list thereon, maintain and increase when necessary such listing, of,
all shares of Warrant Stock from time to time issued upon exercise of this
Warrant or as otherwise provided hereunder, and, to the extent permissible under
the applicable securities exchange rules, all unissued shares of Warrant Stock
which are at any time issuable hereunder, so long as any shares of Common Stock
shall be so listed.  The Issuer will also so list on each securities exchange or
market, and will maintain such listing of, any other securities which the Holder
of this Warrant shall be entitled to receive upon the exercise of this Warrant
if at the time any securities of the same class shall be listed on such
securities exchange or market by the Issuer.

                                      -4-
<PAGE>

     (c)  Covenants.  The Issuer shall not by any action including, without
          ---------
limitation, amending the Certificate of Incorporation or the by-laws of the
Issuer, or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities or any other action, avoid or
seek to avoid the observance or performance of any of the terms or provisions of
this Warrant, but will at all times in good faith carry out all such terms or
provisions and take all such actions as may be necessary or appropriate to
protect the rights of the Holder hereof against dilution (to the extent
specifically provided herein) or impairment.  Without limiting the generality of
the foregoing, the Issuer will (i) not permit the par value, if any, of its
Common Stock to exceed the then effective Warrant Price, (ii) take all such
action as may be reasonably necessary in order that the Issuer may validly and
legally issue fully paid and nonassessable shares of Common Stock, free and
clear of any liens, security interests, charges, claims, encumbrances and
restrictions (other than as provided herein) upon the exercise of this Warrant,
and (iii) obtain all such authorizations, exemptions or consents from any public
regulatory body having jurisdiction thereof as may be necessary to enable the
Issuer to perform its obligations under this Warrant.

     (d)  Loss, Theft, Destruction of Warrants.  Upon receipt of evidence
          ------------------------------------
satisfactory to the Issuer of the ownership of and the loss, theft, destruction
or mutilation of any Warrant and, in the case of any such loss, theft or
destruction, upon receipt of indemnity or security satisfactory to the Issuer
or, in the case of any such mutilation, upon surrender and cancellation of such
Warrant, the Issuer will make and deliver, in lieu of such lost, stolen,
destroyed or mutilated Warrant, a new Warrant of like tenor and representing the
right to purchase the same number of shares of Common Stock.

     (e)  Rights and Obligations under the Registration Rights Agreement.  The
          --------------------------------------------------------------
shares of Warrant Stock are entitled to the benefits and subject to the terms of
the Registration Rights Agreement dated as of even date herewith between the
Issuer and the Holders listed on the signature pages thereof (as amended from
time to time, the "Registration Rights Agreement").  The Issuer shall keep or
cause to be kept a copy of the Registration Rights Agreement, and any amendments
thereto, at its chief executive office and shall furnish, without charge, copies
thereof to the Holder upon request.

     4.   Adjustment of Warrant Price and Warrant Share Number.  The number and
          ----------------------------------------------------
kind of Securities purchasable upon the exercise of this Warrant and the Warrant
Price shall be subject to adjustment from time to time upon the happening of
certain events as follows:

     (a)  Recapitalization, Reorganization, Reclassification, Consolidation,
          ------------------------------------------------------------------
Merger or Sale.
--------------

          (i) In case the Issuer after the Original Issue Date shall do any of
     the following (each, a "Triggering Event"): (a) consolidate with or merge
     into any other Person and the Issuer shall not be the continuing or
     surviving Person of such consolidation or merger, or (b) permit any other
     Person to consolidate with or merge into the Issuer and the Issuer shall be
     the continuing or surviving Person but, in connection with such
     consolidation or merger, any Capital Stock of the Issuer shall be changed
     into or exchanged for Securities of any other Person or cash or any other
     property, or (c) transfer all or substantially all of its properties or
     assets to any other Person, or (d) effect a capital reorganization or
     reclassification of its Capital Stock, then, and in the case of

                                      -5-
<PAGE>

     each such Triggering Event, proper provision shall be made so that, upon
     the basis and the terms and in the manner provided in this Warrant, the
     Holder of this Warrant shall be entitled, at the option of such Holder, (x)
     upon the exercise hereof at any time after the consummation of such
     Triggering Event, to the extent this Warrant is not exercised prior to such
     Triggering Event, to receive at the Warrant Price in effect at the time
     immediately prior to the consummation of such Triggering Event in lieu of
     the Common Stock issuable upon such exercise of this Warrant prior to such
     Triggering Event, the Securities, cash and property to which such Holder
     would have been entitled upon the consummation of such Triggering Event if
     such Holder had exercised the rights represented by this Warrant
     immediately prior thereto, subject to adjustments (subsequent to such
     corporate action) as nearly equivalent as possible to the adjustments
     provided for in Section 4 hereof.

          (ii) Notwithstanding anything contained in this Warrant to the
     contrary, the Issuer will not effect any Triggering Event unless, prior to
     the consummation thereof, each Person (other than the Issuer) which may be
     required to deliver any Securities, cash or property upon the exercise of
     this Warrant as provided herein shall assume, by written instrument
     delivered to, and reasonably satisfactory to, the Holder of this Warrant,
     (A) the obligations of the Issuer under this Warrant (and if the Issuer
     shall survive the consummation of such Triggering Event, such assumption
     shall be in addition to, and shall not release the Issuer from, any
     continuing obligations of the Issuer under this Warrant) and (B) the
     obligation to deliver to such Holder such shares of Securities, cash or
     property as, in accordance with the foregoing provisions of this subsection
     (a), such Holder shall be entitled to receive.

     (b)  Subdivision or Combination of Shares.  If the Issuer, at any time
          ------------------------------------
while this Warrant is outstanding, shall subdivide or combine any shares of
Common Stock, (i) in case of subdivision of shares, the Warrant Price shall be
proportionately reduced (as at the effective date of such subdivision or, if the
Issuer shall take a record of holders of its Common Stock for the purpose of so
subdividing, as at the applicable record date, whichever is earlier) to reflect
the increase in the total number of shares of Common Stock outstanding as a
result of such subdivision, or (ii) in the case of a combination of shares, the
Warrant Price shall be proportionately increased (as at the effective date of
such combination or, if the Issuer shall take a record of holders of its Common
Stock for the purpose of so combining, as at the applicable record date,
whichever is earlier) to reflect the reduction in the total number of shares of
Common Stock outstanding as a result of such combination.

     (c)  Certain Dividends and Distributions.  If the Issuer, at any time while
          -----------------------------------
this Warrant is outstanding, shall:

          (i) Stock Dividends.  Pay a dividend in, or make any other
              ---------------
     distribution to its stockholders (without consideration therefor) of,
     shares of Common Stock, the Warrant Price shall be adjusted, as at the date
     the Issuer shall take a record of the holders of the Issuer's Capital Stock
     for the purpose of receiving such dividend or other distribution (or if no
     such record is taken, as at the date of such payment or other
     distribution), to that price determined by multiplying the Warrant Price in
     effect immediately prior to such record date (or if no such record is
     taken, then immediately prior to such payment or

                                      -6-
<PAGE>

     other distribution), by a fraction (1) the numerator of which shall be the
     total number of shares of Common Stock outstanding immediately prior to
     such dividend or distribution, and (2) the denominator of which shall be
     the total number of shares of Common Stock outstanding immediately after
     such dividend or distribution (plus in the event that the Issuer paid cash
     for fractional shares, the number of additional shares which would have
     been outstanding had the Issuer issued fractional shares in connection with
     said dividends); or

          (ii) Other Dividends.  Pay a dividend on, or make any distribution of
               ---------------
     its assets upon or with respect to (including, but not limited to, a
     distribution of its property as a dividend in liquidation or partial
     liquidation or by way of return of capital), the Common Stock (other than
     as described in clause (i) of this subsection (c) or a cash dividend or
     distribution), or in the event that the Company shall offer options or
     rights to subscribe for shares of Common Stock, or issue any Common Stock
     Equivalents, to all of its holders of Common Stock, then on the record date
     for such payment, distribution or offer or, in the absence of a record
     date, on the date of such payment, distribution or offer, the Holder shall
     receive what the Holder would have received had it exercised this Warrant
     in full immediately prior to the record date of such payment, distribution
     or offer or, in the absence of a record date, immediately prior to the date
     of such payment, distribution or offer

     (d)  Other Action Affecting Common Stock.  In case after the Original Issue
          -----------------------------------
Date the Issuer shall take any action affecting its Common Stock, other than an
action described in any of the foregoing subsections (a) through (d) of this
Section 4, inclusive, and the failure to make any adjustment would not fairly
protect the purchase rights represented by this Warrant in accordance with the
essential intent and principle of this Section 4, then the Warrant Price shall
be adjusted in such manner and at such time as the Board may in good faith
determine to be equitable in the circumstances.

     (e)  Adjustment of Warrant Share Number.  Upon each adjustment in the
          ----------------------------------
Warrant Price pursuant to any of the foregoing provisions of this Section 4, the
Warrant Share Number shall be adjusted, to the nearest one hundredth of a whole
share, to the product obtained by multiplying the Warrant Share Number
immediately prior to such adjustment in the Warrant Price by a fraction, the
numerator of which shall be the Warrant Price immediately before giving effect
to such adjustment and the denominator of which shall be the Warrant Price
immediately after giving effect to such adjustment.  If the Issuer shall be in
default under any provision contained in Section 3 of this Warrant so that
shares issued at the Warrant Price adjusted in accordance with this Section 4
would not be validly issued, the adjustment of the Warrant Share Number provided
for in the foregoing sentence shall nonetheless be made and the Holder of this
Warrant shall be entitled to purchase such greater number of shares at the
lowest price at which such shares may then be validly issued under applicable
law.  Such exercise shall not constitute a waiver of any claim arising against
the Issuer by reason of its default under Section 3 of this Warrant.

     (f)  Form of Warrant after Adjustments.  The form of this Warrant need not
          ---------------------------------
be changed because of any adjustments in the Warrant Price or the number and
kind of Securities purchasable upon the exercise of this Warrant.

                                      -7-
<PAGE>

     5.   Notice of Adjustments.  Whenever the Warrant Price or Warrant Share
          ---------------------
Number shall be adjusted pursuant to Section 4 hereof (for purposes of this
Section 5, each an "adjustment"), the Issuer shall cause its Chief Financial
Officer to prepare and execute a certificate setting forth, in reasonable
detail, the event requiring the adjustment, the amount of the adjustment, the
method by which such adjustment was calculated (including a description of the
basis on which the Board made any determination hereunder), and the Warrant
Price and Warrant Share Number after giving effect to such adjustment, and shall
cause copies of such certificate to be delivered to the Holder of this Warrant
promptly after each adjustment.  Any dispute between the Issuer and the Holder
of this Warrant with respect to the matters set forth in such certificate may at
the option of the Holder of this Warrant be submitted to one of the national
accounting firms currently known as the "big five" selected by the Holder,
provided that the Issuer shall have ten (10) days after receipt of notice from
such Holder of its selection of such firm to object thereto, in which case such
Holder shall select another such firm and the Issuer shall have no such right of
objection.  The firm selected by the Holder of this Warrant as provided in the
preceding sentence shall be instructed to deliver a written opinion as to such
matters to the Issuer and such Holder within thirty (30) days after submission
to it of such dispute.  Such opinion shall be final and binding on the parties
hereto.  The fees and expenses of such accounting firm shall be paid by the
Issuer.

     6.   Fractional Shares.  No fractional shares of Warrant Stock will be
          -----------------
issued in connection with and exercise hereof, but in lieu of such fractional
shares, the Issuer shall make a cash payment therefor equal in amount to the
product of the applicable fraction multiplied by the Per Share Market Value then
in effect.
