                  WARRANT TO PURCHASE SERIES E PREFERRED STOCK

         This Warrant is issued, for good and valuable consideration of $1.00,
receipt of which is hereby acknowledged, to SDK Incorporated (the
"Warrantholder"), by ProBusiness, Inc., a California corporation (the "Company")
located at 5934 Gibraltar, Pleasanton, California 94566. Unless otherwise
stated, all capitalized terms herein have the meaning provided in the Warrant
Purchase Agreement between the Warrantholder, T. J. Bristow, Elizabeth S.
Bristow, Magdalena Shushan, Laurence Shushan and the Company dated November 14,
1996 (the "Warrant Purchase Agreement").

         14. Purchase of Shares. Subject to the terms and conditions hereinafter
set forth, the Warrantholder is entitled, upon surrender of this Warrant at the
principal office of the Company (or at such other place as the Company shall
notify the holder hereof in writing), to purchase from the Company, if and to
the extent permitted by law, 20,250 fully paid and nonassessable shares of
Series E Preferred Stock of the Company (the "Shares") at an exercise price of
$7.94 per share, subject to adjustment as provided in Section 7 hereof (the
"Warrant Price"), payable in cash or by check unless exercised pursuant to
Section 4 hereof.

         15. Exercise Period. The purchase rights represented by this Warrant
shall become exercisable on the date that Britannia Hacienda V Limited
Partnership ("Landlord") notifies the Company that the work to be constructed by
Landlord pursuant to Section 2.4 and Exhibit C of the



                                      -1-
   2
Build-to-Suit Lease dated September 27, 1996 between Landlord and the Company
(the "Lease Agreement") on the shell and core of the Building (as that term is
defined in the Lease Agreement) and the first phase of the interior improvements
of the Building (as more particularly described in the Lease Agreement) is
substantially complete (as that term is defined in the Lease Agreement) and such
work is, in fact, substantially complete. The period during which the purchase
rights represented by this Warrant are exercisable (the "Exercise Period") shall
end on the earlier of (i) five (5) years after the date of the consummation of a
public offering of the Company that triggers the automatic conversion of Series
E Preferred Stock of the Company into Common Stock under the Company's Articles
of Incorporation (an "Initial Public Offering") or (ii) eight (8) years from the
date of this Warrant as set forth on the first page hereof.

         16. Method of Exercise. While this Warrant remains outstanding and
exercisable in accordance with Section 2 above, the holder may exercise, in
whole or in part, the purchase rights evidenced hereby. Such exercise shall be
effected by:

                  (i) the surrender of this Warrant, together with the Form of
Subscription attached hereto as Exhibit 1, duly filled in and executed by the
Warrantholder, to the Secretary of the Company at its principal offices; and

                  (ii) the payment to the Company of an amount equal to the
aggregate purchase price for the Shares being purchased, unless exercised
pursuant to Section 4 hereof.

         17. Conversion Right. During the Exercise Period (and subject to the
conditions set forth in Section 2) and in lieu of exercising this Warrant as
specified in Section 3, Warrantholder may from time to time convert this
Warrant, in whole or in part (but not for a fraction of a share), 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 Warrant Price of such Shares by (b) the fair market value of
one Share.

         18. Fair Market Value. The fair market value per share of the Shares
shall be equal to: (i) if the Common Stock issuable upon conversion of the
Shares is listed on a national stock exchange or over the counter market, then
the price per share listed on such national stock exchange, or the average of
the final "bid" and "asked" prices reported on such over the counter market, at
the close of business on the date of exercise as reported in the Wall Street
Journal multiplied by the quotient of (x) $7.94 divided by (y) the Series E
Conversion Price (as defined in the Company's Articles of Incorporation); or
(ii) if the Common Stock issuable upon the conversion of the Shares is not
listed on a national stock exchange or over the counter market, the Board of
Directors of the Company shall determine the fair market value per share of the
Shares in its reasonable good faith judgment.

         19. Certificates for Shares; Partial Exercise. Upon the exercise of the
purchase rights evidenced by this Warrant, one or more certificates for the
Shares so purchased shall be issued to the Warrantholder as soon as practicable
thereafter. In the case of a partial exercise, unless the purchase rights
evidenced hereby have expired, the Company shall issue to the Warrantholder a
new Warrant,


                                       -2-
   3
dated as of the same date as this Warrant, for the number of Shares, if any,
which remain exercisable hereunder.


         20. Adjustment of Number of Shares and Warrant Price. The number and
kind of securities purchasable upon the exercise of the purchase rights
evidenced by this Warrant and the Warrant Price shall be subject to adjustment
from time to time upon the occurrence of certain events, as follows:

                   (i) Subdivision or Combination of Shares. If the Company at
any time while this Warrant remains outstanding and unexpired shall subdivide or
combine the class of the Company's securities purchasable upon exercise of this
Warrant, whether by way of stock split, stock dividend, recapitalization or
otherwise, the Warrant Price shall, in the case of a subdivision, be
proportionately decreased or, in the case of a combination, be proportionately
increased.

                  (ii) Adjustment of Number of Shares. Upon each adjustment in
the Warrant Price, the number of Shares of the class of the Company's securities
purchasable upon exercise of this Warrant shall, in the case of an increase in
the Warrant Price, be proportionately decreased or, in the case of a decrease in
the Warrant Price, be proportionately increased, in either case to the nearest
whole share.

                  (iii) Reorganization, Reclassification, Consolidation, Merger
or Sale. In case of any reclassification or change of outstanding securities of
the class purchasable upon exercise of this Warrant (other than as set forth in
Section 7(i)) as a result of any reorganization of the capital stock of the
Company, or any consolidation or merger of the Company with another corporation,
or the sale of substantially all of the Company's assets to another corporation,
the Company or its successor, as applicable, shall execute a new Warrant
providing that the Warrantholder shall have the right to exercise such new
Warrant for, in lieu of each share of the class of the Company's securities
theretofore purchasable upon exercise of this Warrant, the kind and amount of
shares of stock, other securities, money and property receivable upon such
reclassification or change by a holder of one share of the class of the
Company's securities theretofore purchasable upon exercise of this Warrant. Such
new Warrant shall provide for adjustments which shall be as nearly equivalent as
may be practicable to the adjustments provided for in this Section 7. The
provisions of this Section 7(iii) shall apply similarly to successive
reclassifications and changes.

                  (iv) Dividends in Stock or Property. If at any time or from
time to time prior to commencement of the Exercise Period the holders of the
Company's Common Stock or of any other class of the Company's securities
purchasable upon exercise of this Warrant shall, as a class, receive or become
entitled to receive, without payment therefor, any shares of stock or other
securities of the Company, any rights or options to acquire or subscribe for any
such shares of stock or other securities, or any other property (including cash)
distributable other than as a cash dividend (collectively, a "Distribution"),
and if no adjustment is made pursuant to Section 7(i), (ii) or (iii) above with
respect to such Distribution, then in each such case, the Warrantholder shall,
upon exercise of this Warrant, be entitled to receive, in addition to the shares
otherwise purchasable upon exercise of this Warrant and without payment of any
additional consideration therefor, the amount of stock, other securities and
other property (other than cash distributed as a cash dividend) which the
Warrantholder would hold or be

                                      -3-
   4
entitled to receive on the date of such exercise had the Warrantholder been the
holder of record, as of the date of such Distribution, of the shares purchased
by the Warrantholder upon such exercise.

                   (v) Certain Other Events. If any change in the shares of the
class of the Company's securities purchasable upon exercise of this Warrant or
any other event occurs as to which the other provisions of this Section 7 are
not strictly applicable or if strictly applicable would not fairly protect the
reasonable expectations of Warrantholder with respect to its purchase rights
under this Warrant, then the Board of Directors of the Company shall make an
adjustment in the number and class of shares purchasable under this Warrant, the
Warrant Price or the other terms and provisions of this Warrant, so as to
protect such reasonable expectations of Warrantholder by giving Warrantholder,
upon exercise of this Warrant for the same aggregate Warrant Price payable for
full exercise of this Warrant prior to such event, the total number, class and
kind of shares (or the closest then available equivalent thereto) as
Warrantholder would have owned had this Warrant been exercised prior to such
event and had Warrantholder continued to hold such shares until after the event
requiring such adjustment.

         21. Notice of Adjustments. Whenever the Warrant Price or other terms of
this Warrant shall be adjusted pursuant to Section 7 hereof, the Company shall
deliver to the Warrantholder a certificate signed by the Company's chief
financial officer describing, in reasonable detail, the event requiring the
adjustment and the newly adjusted Warrant Price and, as applicable, the kind and
amount of shares of stock, other securities, money or property purchasable
hereunder after giving effect to such adjustment.

         22. Fractional Shares. No fractional shares shall be issued in
connection with any exercise hereunder, but in lieu of any such fractional
shares the Company shall make a cash payment therefor in an amount equal to the
difference between the fair market value of such fractional Share as of the date
of exercise and the Warrant Price then in effect with respect to such fractional
Share.

         23. Reservation of Shares. The Company covenants that it will at all
times keep available such number of authorized shares of its Series E Preferred
Stock and Common Stock issuable upon conversion of such Series E Preferred
Stock, free from all preemptive rights with respect thereto, as will be
sufficient to permit the exercise of this Warrant for the full number of Shares
specified herein. The Company further covenants that such Shares, when issued
pursuant to the exercise of this Warrant, and the Common Stock issuable upon
conversion of the Shares, when issued pursuant to such conversion, will be duly
and validly issued, fully paid and non-assessable and free from all taxes, liens
and charges with respect to the issuance thereof.

         24. Rights Prior to Exercise. Prior to exercise of this Warrant, this
Warrant shall not entitle the Warrantholder to any rights of a shareholder with
respect to the Shares, including (without limitation) the right to vote such
Shares, receive preemptive rights or be notified of shareholder meetings, nor
shall this Warrant entitle such Warrantholder to any notice or other
communication concerning the business or affairs of the Company except as set
forth in Section 22 hereof.

         25. Representations of Warrantholder. Warrantholder hereby represents
and warrants to the Company, with respect to its purchase of this Warrant and
the underlying securities issuable upon the

                                      -4-
   5
exercise of this Warrant, that the representations and warranties made by
Warrantholder to the Company in Section 2 of the Warrant Purchase Agreement are
true and correct in all material respects as of the date of this Warrant.

         26. Registration Rights. The registration rights of the Warrantholder
with respect to this Warrant and the underlying securities are set forth in the
Registration Rights Agreement dated December 1, 1989 between the Company and the
persons named therein as amended by the Twentieth Amendment to Registration
Rights Agreement, dated the date hereof, by and among the Company and the
Warrantholders set forth therein.

         27. Non-Assignability and Non-Transferability of Warrant. This Warrant
is not assignable or otherwise transferable by the Warrantholder without the
prior written consent of the Company, except that Warrantholder shall be
entitled to transfer this Warrant, without the Company's consent but with prior

terms of the Warrant Purchase Agreement and this Warrant. The terms and
provisions of this Warrant shall inure to the benefit of, and be binding upon,
Warrantholder and the Company and their respective permitted successors and
assigns.

         28. Governing Law. This Warrant shall be governed by the laws of the

of all or substantially all of the Company's assets in any one transaction or
series of related transactions. All of the obligations of the Company relating
to the Series E Preferred Stock issuable upon the exercise of this Warrant shall

                                      -5-
