THIS WARRANT AND THE SECURITIES ISSUABLE UPON ITS EXERCISE (TOGETHER, THE
"SECURITIES") HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED (THE "ACT"), AND MAY NOT BE TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE
REGISTRATION UNDER THE ACT OR IN A TRANSACTION WHICH QUALIFIES AS AN EXEMPT
TRANSACTION UNDER THE ACT AND THE RULES AND REGULATIONS PROMULGATED THEREUNDER.

Date: September 28, 1999

                                 Commerx, Inc.

                   Series B Preferred Stock Purchase Warrant

     Commerx, Inc., a Delaware corporation (the "Company"), hereby certifies
that, for value received, David Dill (the "Holder"), or assigns, is entitled,
subject to the terms set forth below, to purchase from the Company, at any time
and from time to time during the period beginning on the closing of a private
placement of the Company's Series B Preferred Stock and ending on September 28,
2004, an aggregate number of fully paid and non-assessable shares of the
Company's Series B Preferred Stock at the "Purchase Price" (as hereinafter
defined), subject to the provisions of Paragraph 3 hereof, determined by a
fraction, the numerator of which is fifteen percent (.15) multiplied by
$1,000,000, plus accrued and unpaid interest under the Company's Convertible
Note issued to the holder concurrently with this Warrant, and the denominator of
which is the Purchase Price.  "Purchase Price" shall mean the conversion price
of the Series B Preferred Stock as determined by paragraph 4 of the Convertible
Note.  "Series B Preferred Stock" shall mean, unless the context otherwise
requires, the Series B Preferred Stock issued in accordance with a proposed
amendment to the Company's Certificate of Incorporation, which stock shall have
the rights and preferences substantially as set forth in the Term Sheet attached
hereto and which stock shall be convertible into the Company's Common Stock at
the applicable conversion price as determined by paragraph 4 of the Convertible
Note.  Notwithstanding the foregoing, the Purchase Price and the number and
character of shares issuable under this Warrant are subject to adjustment as set
forth in Paragraph 3.  If the Company consummates an initial public offering of
its common stock prior to exercise of this Warrant, then this Warrant shall be
null and void and the Company shall issue a replacement warrant for the purchase
of Common Stock on equitable terms.  This Warrant and any replacement warrant is
herein called the "Warrant."

     1.  EXERCISE OF WARRANT.  The purchase rights evidenced by this Warrant
shall be exercised by the holder hereof by surrendering this Warrant, with the
form of subscription at the end hereof duly executed by such holder, to the
Company at its office at 350 North LaSalle Street, Suite 1000, Chicago, Illinois
60610, or such other address as the Company may specify by written notice to the
registered holder hereof, accompanied by payment, in cash, by certified or
official bank check or by wire transfer of an amount equal to the Purchase Price
multiplied by the number of shares being purchased pursuant to such exercise of
the Warrant.

          1.1.  Partial Exercise.  This Warrant may be exercised for less than
                ----------------
the full number of shares of Series B Preferred Stock, in which case the number
of shares receivable upon the exercise of this Warrant as a whole, and the sum
payable upon the exercise of this Warrant as a whole, shall be proportionately
reduced. Upon any such partial exercise, the Company at its expense will
forthwith issue to the holder hereof a new Warrant or Warrants of
<PAGE>

like tenor calling for the number of shares of Series B Preferred Stock as to
which rights have not been exercised, such Warrant or Warrants to be issued in
the name of the holder hereof or his nominee (upon payment by such holder of any
applicable transfer taxes).

          1.2.  Net Issue Exercise.
                ------------------

               (1)  In lieu of exercising this Warrant, holder may elect to
receive shares equal to the value of this Warrant (or the portion thereof being
canceled) by surrender of this Warrant at the principal office of the Company
together with notice of such election in which event the Company shall issue to
holder that number of shares of the Company's Series B Preferred Stock computed
using the following formula:

                                  X = Y(A-B)
                                      ------
                                         A

Where

          X.   the number of shares of Series B Preferred Stock to be issued to
               Holder.

          Y.   the number of shares of Series B Preferred Stock purchasable
               under this Warrant.

          A.   the fair market value of one share of the Company's Series B
               Preferred Stock.

          B.   the Purchase Price (as adjusted to the date of such
               calculations).

          (2)  For purposes of this Section, the fair market value of one share
of the Company's Series B Preferred Stock shall be the applicable conversion
price of the Series B Preferred Stock.

     2.   DELIVERY OF STOCK CERTIFICATES ON EXERCISE.  As soon as practicable
after the exercise of this Warrant and payment of the Purchase Price, and in any
event within ten (10) days thereafter, the Company, at its expense, will cause
to be issued in the name of and delivered to the holder hereof a certificate or
certificates for the number of fully paid and non-assessable shares or other
securities or property to which such holder shall be entitled upon such
exercise, plus cash in lieu of any fractional share to which such holder would
otherwise be entitled.  The Company agrees that the shares so purchased shall be
deemed to be issued to the holder hereof as the record owner of such shares as
of the close of business on the date on which this Warrant shall have been
surrendered and payment made for such shares as aforesaid.

     3.   ANTI-DILUTION PROVISIONS AND OTHER ADJUSTMENTS.  In order to prevent
dilution of the right granted hereunder, the Purchase Price shall be subject to
adjustment from time to time in accordance with the provisions of the Company's
Series B Preferred Stock.

     If any event occurs as to which, in the opinion of the Board of Directors
of the Company, the provisions of the Company's Series B Preferred Stock
relating to anti-dilution and other adjustments are not strictly applicable or
if strictly applicable would not fairly protect the rights
<PAGE>

of the holder of this Warrant in accordance with the essential intent and
principles of such provisions, then the Board of Directors shall make an
adjustment in the application of such provisions, in accordance with such
essential intent and principles, so as to protect such rights as aforesaid.

     4.   NO DILUTION OR IMPAIRMENT.  The Company will not, by amendment of its
charter or through reorganization, consolidation, merger, dissolution, sale of
assets or any other voluntary action, avoid or seek to avoid the observance or
performance of any of the terms of this Warrant, but will at all times in good
faith assist in the carrying out of all such terms and in the taking of all such
action as may be necessary or appropriate in order to protect the rights of the
holder hereof against dilution or other impairment.  The Company shall at all
times take all such action as may be necessary or appropriate in order that the
Company may validly and legally issue fully paid and non-assessable stock upon
the exercise of this Warrant.

     5.   RESERVATION OF STOCK ISSUABLE ON EXERCISE OF WARRANTS.  The Company
shall at all times reserve and keep available out of its authorized but unissued
stock, solely for the issuance and delivery upon the exercise of this Warrant
and other similar Warrants, such number of its duly authorized shares of Series
B Preferred Stock as from time to time shall be issuable upon the exercise of
this Warrant and all other similar Warrants at the time outstanding.  All of the
shares of Series B Preferred Stock issuable upon exercise of this Warrant, when
issued and delivered in accordance with the terms hereof, will be duly
authorized, validly issued, fully-paid and non-assessable.

     6.   REPLACEMENT OF WARRANT.  Upon 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) upon delivery of an
indemnity agreement (with surety if reasonably required) in an amount reasonably
satisfactory to it, or (in the case of mutilation) upon surrender and
cancellation thereof, the Company will issue, in lieu thereof, a new Warrant of
like tenor.

     7.   REMEDIES.  The Company stipulates that the remedies at law of the
holder of this Warrant in the event of any default by the Company in the
performance of or compliance with any of the terms of this Warrant are not and
will not be adequate, and that the same may be specifically enforced.

     8.   REGISTRATION RIGHTS.  The shares of Series B Preferred Stock issuable
upon exercise of this Warrant and securities issued upon conversion of such
stock are subject to the registration rights granted to Series B Preferred
Stockholders.

     9.   NEGOTIABILITY.  This Warrant is issued upon the following terms, to
all of which each taker or owner hereof consents and agrees:

          (a) Absent an effective registration statement under the Securities
Act of 1933, as amended (the "Act"), covering the disposition of this Warrant or
the shares of Series B Preferred Stock issued or issuable upon exercise hereof,
the holder will not sell or transfer any or all of such Warrant or shares, as
the case may be, without first providing the Company with an opinion of counsel
(which may be counsel for the Company) to the effect that such sale or
<PAGE>

transfer will be exempt from the registration and prospectus delivery
requirements of the Act. Each certificate representing shares of Series B
Preferred Stock issued pursuant to this Warrant shall bear a legend in
substantially the following form on the face thereof:

          THESE SECURITIES HAVE NOT BEEN REGISTERED
          UNDER THE SECURITIES ACT OF 1933 OR APPLICABLE
          STATE SECURITIES LAWS AND MAY BE TRANSFERRED
          OR RESOLD ONLY IN COMPLIANCE WITH SUCH
          SECURITIES LAWS.

Any certificate representing securities issued at any time in exchange or
substitution for any certificate bearing such legend (except a certificate
issued upon completion of a distribution under a registration statement covering
the securities represented) shall also bear such legend unless, in the opinion
of counsel to the Company, the securities represented thereby may be transferred
as contemplated by such holder without violation of the registration
requirements of the Act.

          (b) Any person in possession of this Warrant properly endorsed is
authorized to represent itself as absolute owner hereof and is granted power to
transfer absolute title hereto by endorsement and delivery hereof to a bona fide
purchaser hereof for value; each prior taker or owner waives and renounces all
of its equities or rights in this Warrant in favor of every such bona fide
purchaser, and every such, bona fide purchaser shall acquire title hereto and to
all rights represented hereby.

          (c) Until this Warrant is transferred on the books of the Company, the
Company may treat the registered holder of this Warrant as the absolute owner
hereof for all purposes without being affected by any notice to the contrary.

          (d) Prior to the exercise of this Warrant, the holder hereof shall not
be entitled to any rights of a shareholder of the Company with respect to shares
for which this Warrant shall be exercisable, including, without limitation, the
right to vote, to receive dividends or other distributions or to exercise any
preemptive rights, and shall not be entitled to receive any notice of any
proceedings of the Company, except as provided herein.

          (e) The Company shall not be required to pay any Federal or state
transfer tax or charge that may be payable in respect of any transfer involved
in the transfer or delivery of this Warrant or the issuance or conversion or
delivery of certificates for Series B Preferred Stock in a name other than that
of the registered holder of this Warrant or to issue or deliver any certificates
for Series B Preferred Stock upon the exercise of this Warrant until any and all
such taxes and charges shall have been paid by the holder of this Warrant or
until it has been established to the Company's satisfaction that no such tax or
charge is due.

Date: September 28, 1999

                                 Commerx, Inc.

                   Series B Preferred Stock Purchase Warrant

     Commerx, Inc., a Delaware corporation (the "Company"), hereby certifies
that, for value received, Jeff Garwood (the "Holder"), or assigns, is entitled,
subject to the terms set forth below, to purchase from the Company, at any time
and from time to time during the period beginning on the closing of a private
placement of the Company's Series B Preferred Stock and ending on September 28,
2004, an aggregate number of fully paid and non-assessable shares of the
Company's Series B Preferred Stock at the "Purchase Price" (as hereinafter
defined), subject to the provisions of Paragraph 3 hereof, determined by a
fraction, the numerator of which is fifteen percent (.15) multiplied by
$600,000, plus accrued and unpaid interest under the Company's Convertible Note
issued to the holder concurrently with this Warrant, and the denominator of
which is the Purchase Price.  "Purchase Price" shall mean the conversion price
of the Series B Preferred Stock as determined by paragraph 4 of the Convertible
Note.  "Series B Preferred Stock" shall mean, unless the context otherwise
requires, the Series B Preferred Stock issued in accordance with a proposed
amendment to the Company's Certificate of Incorporation, which stock shall have
the rights and preferences substantially as set forth in the Term Sheet attached
hereto and which stock shall be convertible into the Company's Common Stock at
the applicable conversion price as determined by paragraph 4 of the Convertible
Note.  Notwithstanding the foregoing, the Purchase Price and the number and
character of shares issuable under this Warrant are subject to adjustment as set
forth in Paragraph 3.  If the Company consummates an initial public offering of
its common stock prior to exercise of this Warrant, then this Warrant shall be
null and void and the Company shall issue a replacement warrant for the purchase
of Common Stock on equitable terms.  This Warrant and any replacement warrant is
herein called the "Warrant."

     1.   EXERCISE OF WARRANT.  The purchase rights evidenced by this Warrant
shall be exercised by the holder hereof by surrendering this Warrant, with the
form of subscription at the end hereof duly executed by such holder, to the
Company at its office at 350 North LaSalle Street, Suite 1000, Chicago, Illinois
60610, or such other address as the Company may specify by written notice to the
registered holder hereof, accompanied by payment, in cash, by certified or
official bank check or by wire transfer of an amount equal to the Purchase Price
multiplied by the number of shares being purchased pursuant to such exercise of
the Warrant.

          1.1.  Partial Exercise.  This Warrant may be exercised for less than
                ----------------
the full number of shares of Series B Preferred Stock, in which case the number
of shares receivable upon the exercise of this Warrant as a whole, and the sum
payable upon the exercise of this Warrant as a whole, shall be proportionately
reduced. Upon any such partial exercise, the Company at its expense will
forthwith issue to the holder hereof a new Warrant or Warrants of
<PAGE>

like tenor calling for the number of shares of Series B Preferred Stock as to
which rights have not been exercised, such Warrant or Warrants to be issued in
the name of the holder hereof or his nominee (upon payment by such holder of any
applicable transfer taxes).

          1.2.  Net Issue Exercise.
                ------------------

               (1)  In lieu of exercising this Warrant, holder may elect to
receive shares equal to the value of this Warrant (or the portion thereof being
canceled) by surrender of this Warrant at the principal office of the Company
together with notice of such election in which event the Company shall issue to
holder that number of shares of the Company's Series B Preferred Stock computed
using the following formula:

                                   X =Y(A-B)
                                      ------
                                         A

Where

          X.   the number of shares of Series B Preferred Stock to be issued to
               Holder.

          Y.   the number of shares of Series B Preferred Stock purchasable
               under this Warrant.

          A.   the fair market value of one share of the Company's Series B
               Preferred Stock.

          B.   the Purchase Price (as adjusted to the date of such
               calculations).

          (2)  For purposes of this Section, the fair market value of one share
of the Company's Series B Preferred Stock shall be the applicable conversion
price of the Series B Preferred Stock.

     2.   DELIVERY OF STOCK CERTIFICATES ON EXERCISE.  As soon as practicable
after the exercise of this Warrant and payment of the Purchase Price, and in any
event within ten (10) days thereafter, the Company, at its expense, will cause
to be issued in the name of and delivered to the holder hereof a certificate or
certificates for the number of fully paid and non-assessable shares or other
securities or property to which such holder shall be entitled upon such
exercise, plus cash in lieu of any fractional share to which such holder would
otherwise be entitled.  The Company agrees that the shares so purchased shall be
deemed to be issued to the holder hereof as the record owner of such shares as
of the close of business on the date on which this Warrant shall have been
surrendered and payment made for such shares as aforesaid.

     3.   ANTI-DILUTION PROVISIONS AND OTHER ADJUSTMENTS.  In order to prevent
dilution of the right granted hereunder, the Purchase Price shall be subject to
adjustment from time to time in accordance with the provisions of the Company's
Series B Preferred Stock.

     If any event occurs as to which, in the opinion of the Board of Directors
of the Company, the provisions of the Company's Series B Preferred Stock
relating to anti-dilution and other adjustments are not strictly applicable or
if strictly applicable would not fairly protect the rights
<PAGE>

of the holder of this Warrant in accordance with the essential intent and
principles of such provisions, then the Board of Directors shall make an
adjustment in the application of such provisions, in accordance with such
essential intent and principles, so as to protect such rights as aforesaid.

     4.   NO DILUTION OR IMPAIRMENT.  The Company will not, by amendment of its
charter or through reorganization, consolidation, merger, dissolution, sale of
assets or any other voluntary action, avoid or seek to avoid the observance or
performance of any of the terms of this Warrant, but will at all times in good
faith assist in the carrying out of all such terms and in the taking of all such
action as may be necessary or appropriate in order to protect the rights of the
holder hereof against dilution or other impairment.  The Company shall at all
times take all such action as may be necessary or appropriate in order that the
Company may validly and legally issue fully paid and non-assessable stock upon
the exercise of this Warrant.

     5.   RESERVATION OF STOCK ISSUABLE ON EXERCISE OF WARRANTS.  The Company
shall at all times reserve and keep available out of its authorized but unissued
stock, solely for the issuance and delivery upon the exercise of this Warrant
and other similar Warrants, such number of its duly authorized shares of Series
B Preferred Stock as from time to time shall be issuable upon the exercise of
this Warrant and all other similar Warrants at the time outstanding.  All of the
shares of Series B Preferred Stock issuable upon exercise of this Warrant, when
issued and delivered in accordance with the terms hereof, will be duly
authorized, validly issued, fully-paid and non-assessable.

     6.   REPLACEMENT OF WARRANT.  Upon 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) upon delivery of an
indemnity agreement (with surety if reasonably required) in an amount reasonably
satisfactory to it, or (in the case of mutilation) upon surrender and
cancellation thereof, the Company will issue, in lieu thereof, a new Warrant of
like tenor.

     7.   REMEDIES.  The Company stipulates that the remedies at law of the
holder of this Warrant in the event of any default by the Company in the
performance of or compliance with any of the terms of this Warrant are not and
will not be adequate, and that the same may be specifically enforced.

     8.   REGISTRATION RIGHTS.  The shares of Series B Preferred Stock issuable
upon exercise of this Warrant and securities issued upon conversion of such
stock are subject to the registration rights granted to Series B Preferred
Stockholders.

     9.   NEGOTIABILITY.  This Warrant is issued upon the following terms, to
all of which each taker or owner hereof consents and agrees:

          (a) Absent an effective registration statement under the Securities
Act of 1933, as amended (the "Act"), covering the disposition of this Warrant or
the shares of Series B Preferred Stock issued or issuable upon exercise hereof,
the holder will not sell or transfer any or all of such Warrant or shares, as
the case may be, without first providing the Company with an opinion of counsel
(which may be counsel for the Company) to the effect that such sale or
<PAGE>

transfer will be exempt from the registration and prospectus delivery
requirements of the Act. Each certificate representing shares of Series B
Preferred Stock issued pursuant to this Warrant shall bear a legend in
substantially the following form on the face thereof:

          THESE SECURITIES HAVE NOT BEEN REGISTERED
          UNDER THE SECURITIES ACT OF 1933 OR APPLICABLE
          STATE SECURITIES LAWS AND MAY BE TRANSFERRED
          OR RESOLD ONLY IN COMPLIANCE WITH SUCH
          SECURITIES LAWS.

Any certificate representing securities issued at any time in exchange or
substitution for any certificate bearing such legend (except a certificate
issued upon completion of a distribution under a registration statement covering
the securities represented) shall also bear such legend unless, in the opinion
of counsel to the Company, the securities represented thereby may be transferred
as contemplated by such holder without violation of the registration
requirements of the Act.

          (b)  Any person in possession of this Warrant properly endorsed is
authorized to represent itself as absolute owner hereof and is granted power to
transfer absolute title hereto by endorsement and delivery hereof to a bona fide
purchaser hereof for value; each prior taker or owner waives and renounces all
of its equities or rights in this Warrant in favor of every such bona fide
purchaser, and every such, bona fide purchaser shall acquire title hereto and to
all rights represented hereby.

          (c)  Until this Warrant is transferred on the books of the Company,
the Company may treat the registered holder of this Warrant as the absolute
owner hereof for all purposes without being affected by any notice to the
contrary.

          (d)  Prior to the exercise of this Warrant, the holder hereof shall
not be entitled to any rights of a shareholder of the Company with respect to
shares for which this Warrant shall be exercisable, including, without
limitation, the right to vote, to receive dividends or other distributions or to
exercise any preemptive rights, and shall not be entitled to receive any notice
of any proceedings of the Company, except as provided herein.

          (e)  The Company shall not be required to pay any Federal or state
transfer tax or charge that may be payable in respect of any transfer involved
in the transfer or delivery of this Warrant or the issuance or conversion or
delivery of certificates for Series B Preferred Stock in a name other than that
of the registered holder of this Warrant or to issue or deliver any certificates
for Series B Preferred Stock upon the exercise of this Warrant until any and all
such taxes and charges shall have been paid by the holder of this Warrant or
until it has been established to the Company's satisfaction that no such tax or
charge is due.
