                             DIGITALWORK.COM, INC.

                          STOCK SUBSCRIPTION WARRANT

                                               December 22, 1999

1.   General.
     -------

          (a)  THIS CERTIFIES that, for value received, Dell USA, L.P. ("Dell"),
or assigns, is entitled to subscribe for and purchase from DIGITALWORK.COM,
INC., a Delaware corporation (the "Corporation"), at any time or from time to
time during the period (the "Exercise Period") commencing with the date hereof
and ending on the second anniversary of the date hereof, on the terms and
subject to the provisions hereinafter set forth, up to 150,000 of shares
(subject to adjustment as provided herein) of fully paid and non-assessable
shares of Series D Preferred Stock, $0.005 par value, of the Corporation, at a
price per share (the "Warrant Price") of $8.36 or in the event the Preferred
Stock shall prior to exercise or exchange of this Warrant have been converted
into Common Stock, $0.005 par value (the "Common Stock") of the Corporation as a
result of an automatic conversion event (as defined in Article IV, Section 3.2
of the Amendment of the Amended and Restated Certificate of Incorporation of the
Corporation), that number of shares of Common Stock into which such number of
shares of Preferred Stock is converted ("Mandatory Conversion Event") at any
time or from time to time during the Exercise Period.

The shares of capital stock of the Corporation issuable upon exercise or
exchange of this Warrant are sometimes hereinafter referred to as the "Warrant
Shares," and, in connection therewith, all references herein to Warrant Shares
shall mean Preferred Stock until the occurrence of a Mandatory Conversion Event,
and upon and at all times after, the occurrence of a Mandatory Conversion Event,
shall mean Common Stock.

2.   Exercise of Warrant.
     -------------------

          The rights represented by this Warrant may be exercised by the holder
hereof in whole or in part, at any time or from time to time during the Exercise
Period, by the surrender of
<PAGE>

this Warrant (properly endorsed) at the office of the Corporation at 230 West
Monroe Street, Suite 1950, Chicago, Illinois 60606, or at such other agency or
office of the Corporation in the United States of America as it may designate by
notice in writing to the holder hereof at the address of such holder appearing
on the books of the Corporation, and by payment (either in cash, by check, by
cancellation of indebtedness and/or in shares of capital stock of the
Corporation valued at Fair Market Value (as hereinafter defined) on the date of
such exercise) to the Corporation of the Warrant Price for each Warrant Share
being purchased. In the event of the exercise of the rights represented by this
Warrant, a certificate or certificates for the Warrant Shares so purchased,
registered in the name of the holder, and if this Warrant shall not have been
exercised for all of the Warrant Shares, a new Warrant, registered in the name
of the holder hereof, of like tenor to this Warrant, shall be delivered to the
holder hereof within a reasonable time, not exceeding ten days, after the rights
represented by this Warrant shall have been so exercised. The person in whose
name any certificate for Warrant Shares is issued upon exercise of this Warrant
shall for all purposes be deemed to have become the holder of record of such
shares on the date on which the Warrant was surrendered and payment of the
Warrant Price and any applicable taxes was made, irrespective of the date of
delivery of such certificate, except that, if the date of such surrender and
payment is a date when the stock transfer books of the Corporation are closed,
such person shall be deemed to have become the holder of such shares at the
close of business on the next succeeding date on which the stock transfer books
are open.

3.   Exchange of Warrant.
     -------------------
          (a)  In addition to, and independent of, the rights of the holder of
this Warrant set forth in Section 2 hereof, the holder hereof may at any time or
from time to time elect to receive, without the payment by the holder of any
additional consideration, that number of Warrant Shares determined as
hereinafter provided in this Section 3 by the surrender of this Warrant or any
portion hereof to the Corporation, accompanied by an executed Notice of Exchange
in substantially the form thereof attached hereto (the "Net Issue Election").
Thereupon, the Corporation shall issue to the holder hereof such number of fully
paid and nonassessable Warrant Shares as is computed using the following
formula:

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

where X =  the number of Warrant Shares to be issued to the holder pursuant to
           this Section 3.

      Y =  the number of Warrant Shares covered by this Warrant in respect of
           which the Net Issue Election is made pursuant to this Section 3.

      A =  the Fair Market Value (as hereinafter defined) of one Warrant Share
           determined at the time the Net Issue Election is made pursuant to
           this Section 3 (the "Determination Date").

      B =  the Warrant Price in effect under this Warrant at the time the Net
           Issue Election is made pursuant to this Section 3.

                                       2
<PAGE>

For purposes of the above calculation, "Fair Market Value" of one Warrant Share
as of the Determination Date shall mean:

               (i)   if as a result of a Mandatory Conversion Event the Warrant
Shares mean Common Stock as set forth in Section 1, then (A) if the Common Stock
of the Corporation is not then traded on a national securities exchange, the
average of the closing prices quoted on the National Association of Securities
Dealers, Inc. Automated Quotation National Market System, if applicable, or the
average of the last bid and asked prices of the Common Stock quoted in the over-
the-counter-market or (B) if the Common Stock is then traded on a national
securities exchange, the average of the high and low prices of the Common Stock
listed on the principal national securities exchange on which the Common Stock
is so traded, in each case for the twenty (20) trading days immediately
preceding the Determination Date;

               (ii)  in the event of a Warrant Exchange in connection with a
Corporate Transaction, the value per share of Common Stock received or
receivable by each holder thereof (assuming, in the case of a sale of assets,
the Corporation is liquidated immediately following such sale and the
consideration paid to the Corporation is immediately distributed to its
stockholders); and

               (iii) in all other circumstances, the fair market value per share
of Common Stock as determined by (i) the Corporation's Board of Directors in
good faith after taking into consideration all factors it deems appropriate,
including, without limitation, recent sale and offer prices of the capital stock
of the Corporation in private transactions negotiated at arm's length, or (ii) a
nationally recognized independent investment banking firm jointly selected by
the Corporation and the holder of this Warrant or, if such selection cannot be
made within five business days after delivery of the Notice of Exchange referred
to above, by a nationally recognized independent investment banking firm
selected by the American Arbitration Association then obtaining, at the sole
discretion of AOL.

The closing of any Warrant Exchange shall take place at the offices of the
Corporation on the date specified in the Notice of Exchange (the "Exchange
Date"), which shall be not less than five and not more than 30 days after the
delivery of such Notice.  At such closing, the Corporation shall issue and
deliver to the holder or its designee a certificate or certificates for the
Warrant Shares to be issued upon such Warrant Exchange, registered in the name
of the holder or such designee, and if such Warrant Exchange shall not have been
for all Warrant Shares, a new Warrant, registered in the name of the holder, of
like tenor to this Warrant for the number of shares still subject to this
Warrant following such Warrant Exchange.

4.   Adjustment of Warrant Price.
     ---------------------------

          (a)  The Warrant Price and number of Warrant Shares shall be subject
to adjustment from time to time as follows:

               (i)  If, at any time during the Exercise Period, the number of
shares of Common Stock outstanding is increased by a stock dividend payable in
shares of Common

                                       3
<PAGE>

Stock or by a subdivision or split-up of shares of Common Stock, then, following
the record date fixed for the determination of holders of Common Stock entitled
to receive such stock dividend, subdivision or split-up, the Warrant Price shall
be appropriately decreased and the number of shares of Preferred Stock issuable
upon the exercise of this Warrant or the Common Stock issuable upon conversion
of the Preferred Stock shall be appropriately increased, in each case in
proportion to such increase in outstanding shares.

               (ii)  If, at any time during the Exercise Period, the number of
shares of Common Stock outstanding is decreased by a combination of the
outstanding shares of Common Stock, then, following the record date for such
combination, the Warrant Price shall be appropriately increased and the number
of shares of Preferred Stock issuable upon the exercise of this Warrant or the
Common Stock issuable upon conversion of the Preferred Stock shall be
appropriately decreased, in each case, in proportion to such decrease in
outstanding shares.

               (iii) All calculations under this Section 4 shall be made to the
nearest one tenth (1/10) of a cent or to the nearest one tenth (1/10) of a
share, as the case may be.

          (b)  Whenever the Warrant Price shall be adjusted as provided in this
Section 4 the Corporation shall forthwith file, at the office of the Corporation
or any transfer agent designated by the Corporation for the Common Stock, a
statement, signed by its chief financial officer, showing in detail the facts
requiring such adjustment and the adjusted Warrant Price.  The Corporation shall
also cause a copy of such statement to be sent by first-class certified mail,
return receipt requested, postage prepaid, to each holder of a Warrant at his or
its address appearing on the Corporation's records.  Where appropriate, such
copy may be given in advance and may be included as part of a notice required to
be mailed under the provisions set forth immediately below.

          (c)  In the event the Corporation shall propose to take any action of
the types described in Section 4(a)(i) or (ii) or Section 11, the Corporation
shall give notice to each holder of a Warrant in the manner set forth herein,
which notice shall specify the record date, if any, with respect to any such
action and the date on which such action is to take place.  Such notice shall
also set forth such facts with respect thereto as shall be reasonably necessary
to indicate the effect of such action (to the extent such effect may be known at
the date of such notice) on the Warrant Price then in effect and the number,
kind or class of shares or other securities or property which shall be delivered
or purchasable upon the occurrence of such action or deliverable upon exercise
of this Warrant.  In the case of any action which would require the fixing of a
record date, such notice shall be given at least 20 days prior to the date so
fixed, and in case of all other action, such notice shall be given at least 30
days prior to the taking of such proposed action.  Failure to give such notice,
or any defect therein, shall not affect the legality or validity of any such
action.

                                       4

5.   Covenants as to Preferred Stock.
     --------------------------------

               (a)  The Corporation covenants and agrees that all shares of
Preferred Stock which may be issued upon the exercise of the rights represented
by this Warrant, and all shares of Common Stock which may be issued upon the
conversion of the Preferred Stock will, upon issuance, be validly issued, fully
paid and non-assessable and free from all taxes, liens and charges with respect
to the issuance thereof. The Corporation further covenants and agrees that the
Corporation will from time to time take all such action as may be requisite to
assure that the stated or par value per share of the Preferred Stock and the
Common Stock is at all times equal to or less than the then effective Warrant
Price per share of Preferred Stock issuable upon exercise of this Warrant. The
Corporation further covenants and agrees that the Corporation will at all times
have authorized and reserved, free from preemptive rights, a sufficient number
of (a) shares of its Preferred Stock to provide for the exercise of the rights
represented by this Warrant and (b) shares of Common Stock to provide for the
conversion of the Preferred Stock issuable upon exercise of this Warrant. The
Corporation further covenants and agrees that if any shares of capital stock to
be reserved for the purpose of the issuance of shares of Preferred Stock upon
the exercise of this Warrant require registration with or approval of any
governmental authority under any Federal or state law before such shares may be
validly issued or delivered upon exercise, then the Corporation will in good
faith and expeditiously as possible endeavor to secure such registration or
approval, as the case may be. If and so long as the Preferred Stock or Common
Stock issuable upon the exercise of the rights represented by this Warrant is
listed on any national securities exchange, the Corporation will, if permitted
by the rules of such exchange, list and keep listed on such exchange, upon
official notice of issuance, all shares of such capital stock.

               (b)  The Corporation further covenants and agrees that the holder
hereof will be entitled to the benefits of any adjustment prior to the exercise
hereof pursuant to any anti-dilution protection and any notice of adjustment of
the conversion price provided to the holders of Preferred Stock in accordance
with the Corporation's Certificate of Incorporation.

6.   No Shareholder Rights.
     ---------------------

               This Warrant shall not entitle the holder hereof to any voting
rights or other rights as a shareholder of the Corporation.

7.   Restrictions on Transfer.
     ------------------------

               The holder of this Warrant acknowledges that neither this Warrant
nor the Warrant Shares have been registered under the Securities Act of 1933, as
amended (the "Securities Act") and the holder of this Warrant agrees that no
sale, transfer, assignment, hypothecation or other disposition of this Warrant
or the Warrant Shares shall be made in the absence of (a) current registration
statement under the Securities Act as to this Warrant or the Warrant Shares and
the registration or qualification of this Warrant or the Warrant Shares under
any applicable state securities laws is then in effect or (ii) an opinion of
counsel reasonably satisfactory to the Corporation to the effect that such
registration or qualification is not required.

                                       5

Each certificate or other instrument for Warrant Shares issued upon exercise of
this Warrant shall, if required under the Securities Act or the rules
promulgated thereunder, be imprinted with a legend substantially to the
foregoing effect.

8.   Rights of the Holder.
     --------------------

          (a)  Anything contained herein to the contrary notwithstanding, the
     shares of Preferred Stock issuable upon exercise of this Warrant and the
     Common Stock issuable upon conversion of such shares of Preferred Stock
     shall be entitled to all rights and benefits accorded thereto in any
     investor rights or shareholders or similar agreement between and/or among
     the Corporation and the holders of the Preferred Stock, and the Corporation
     shall take all actions and shall execute and deliver all documents
     necessary or desirable, including any amendments to such agreement(s) to
     make the holder a party thereto.

          (b)  Anything contained herein to the contrary notwithstanding, the
     holder of this Warrant shall be entitled to the rights set forth on
     Exhibit A hereto.
     ---------

 9.  Transfer of Warrant; Amendment.
     ------------------------------

     Subject to the restriction set forth in Section 7, this Warrant and all
rights hereunder are transferable, in whole, or in part, at the agency or office
of the Corporation referred to in Section 2, by the holder hereof in person or
by duly authorized attorney, upon surrender of this Warrant properly endorsed;
provided, however, that prior to the IPO, transfers by any holder of this
--------  -------
Warrant to a person or entity other than an affiliate of such holder shall
require the prior written consent of the Corporation.  Each taker and holder of
this Warrant, by taking or holding the same, consents and agrees that this
Warrant, when endorsed, in blank, shall be deemed negotiable, and, when so
endorsed the holder hereof may be treated by the Corporation and all other
persons dealing with this Warrant as the absolute owner hereof for any purposes
and as the person entitled to exercise the rights represented by this Warrant,
or to the transfer hereof on the books of the Corporation, any notice to the
contrary notwithstanding; but until each transfer on such books, the Corporation
may treat the registered holder hereof as the owner hereof for all purposes.

10.  Reorganizations, Etc.  In case, at any time during the Exercise Period, of
     --------------------
any capital reorganization, of any reclassification of the stock of the
Corporation (other than a change in par value or from par value to no par value
or from no par value to par value or as a result of a stock dividend or
subdivision, split-up or combination of shares), or the consolidation or merger
of the Corporation with or into another corporation (other than a consolidation
or merger in which the Corporation is the continuing operation and which does
not result in any change in the Common Stock) or of the sale of all or
substantially all the properties and assets of the Corporation as an entirety to
any other corporation, this Warrant shall, after such reorganization,
reclassification, consolidation, merger or sale, be exercisable for the kind and
number of shares of stock or other

                                       7
<PAGE>

securities or property of the Corporation or of the corporation resulting from
such consolidation or surviving such merger or to which such properties and
assets shall have been sold to which such holder would have been entitled if he
had held the Preferred Stock issuable upon the exercise of this Warrant or the
Common Stock issuable upon conversion of the Preferred Stock immediately prior
to such reorganization, reclassification, consolidation, merger or sale. In any
such reorganization or other action or transaction described above, appropriate
provision shall be made with respect to the rights and interests of the holder
of this Warrant to the end that the provisions hereof (including, without
limitation, provisions for adjustments of the Warrant Price and of the number of
shares purchasable and receivable upon the exercise of this Warrant) shall
thereafter be applicable, as nearly as may be, in relation to any shares of
stock, securities or assets thereafter deliverable upon the exercise hereof.

11.  Lost, Stolen, Mutilated or Destroyed Warrant.  If this Warrant is lost,
     --------------------------------------------
stolen, mutilated or destroyed, the Corporation may, on such terms as to
indemnity or otherwise as it may in its discretion impose (which shall, in the
case of a mutilated Warrant, include the surrender thereof), issue a new Warrant
of like denomination and tenor as the Warrant so lost, stolen, mutilated or
destroyed.  Any such new Warrant shall constitute an original contractual
obligation of the Corporation, whether or not the allegedly lost, stolen,
mutilated or destroyed Warrant shall be at any time enforceable by anyone.

12.  Modification and Waiver.  This Warrant and any provision hereof may be
     -----------------------
changed, waived, discharged or terminated only by an instrument in writing
signed by the party against which enforcement of the same is sought.

13.  Notices.  All notices, advices and communications to be given or otherwise
     -------
made to any party to this Agreement shall be deemed to be sufficient if
contained in a written instrument delivered in person or by telecopier or duly
sent by first class registered or certified mail, return receipt requested,
postage prepaid, or by overnight courier, or by electronic mail, with a copy
thereof to be sent by mail (as aforesaid) within 24 hours of such electronic

14.  Binding Effect on Successors; Survival.  This Warrant shall be binding upon

acquisition of all or substantially all of the Corporation's assets.  All of the
obligations of the Corporation relating to the Preferred Stock issuable upon the

be governed by, the laws of the Commonwealth of Virginia.

16.  Fractional Shares.  No fractional shares shall be issued upon exercise of
     -----------------
this Warrant.  The Corporation shall, in lieu of issuing any fractional share,
pay the holder entitled to such fraction a sum in cash equal to such fraction
multiplied by the then Fair Market Value of one Warrant Share.
