                                    ADDENDUM
                                       TO
                             STOCK OPTION AGREEMENT

            The following provisions are hereby incorporated into, and are
hereby made a part of, that certain Stock Option Agreement (the "Option
Agreement") by and between EXULT, INC. (the "Corporation") and ("Optionee")
evidencing the stock option (the "Option") granted on this date to Optionee
under the terms of the Corporation's 1999 Special Executive Stock Option/Stock
Issuance Plan, and such provisions shall be effective immediately. All
capitalized terms in this Addendum, to the extent not otherwise defined herein,
shall have the meanings assigned to them in the Option Agreement.

                        INVOLUNTARY TERMINATION FOLLOWING
                              CORPORATE TRANSACTION

            1. To the extent the Option is, in connection with a Corporate
Transaction, to be assumed in accordance with Paragraph 6 of the Option
Agreement, none of the Option Shares shall vest on an accelerated basis upon the
occurrence of that Corporate Transaction, and Optionee shall accordingly
continue, over his or her period of Service following the Corporate Transaction,
to vest in the Option Shares in one or more installments in accordance with the
provisions of the Option Agreement. However, upon an Involuntary Termination of
Optionee's Service within eighteen (18) months following such Corporate
Transaction, all the Option Shares at the time subject to the Option shall
automatically vest in full on an accelerated basis so that the Option shall
immediately become exercisable for all the Option Shares as fully-vested shares
and may be exercised for any or all of those Option Shares as vested shares. The
Option shall remain so exercisable until the earlier of (i) the Expiration Date
or (ii) the expiration of the one (1)-year period measured from the date of the
Involuntary Termination.

            2. For purposes of this Addendum, an INVOLUNTARY TERMINATION shall
mean the termination of Optionee's Service by reason of:

               (i) Optionee's involuntary dismissal or discharge by the
        Corporation for reasons other than for Misconduct, or

               (ii) Optionee's voluntary resignation following (A) a change in
        Optionee's position with the Corporation (or Parent or Subsidiary
        employing Optionee) which materially reduces Optionee's duties and
        responsibilities or the level of management to which he or she reports,
        (B) a reduction in Optionee's level of compensation (including base
        salary, fringe benefits and target bonuses under any
        corporate-performance based incentive programs) by more than fifteen
        percent (15%) or (C) a relocation of Optionee's place of employment by
        more than fifty (50) miles, provided and only if such change, reduction
        or relocation is effected by the Corporation without Optionee's consent.

            3. The provisions of Paragraph 1 of this Addendum shall govern the
period for which the Option is to remain exercisable following the Involuntary
Termination of Optionee's Service within eighteen (18) months after the
Corporate Transaction and shall supersede any provisions to the contrary in
Paragraph 5 of the Option Agreement. The provisions of this Addendum shall also
supersede any provisions to the contrary in Paragraph 18 of the Option Agreement
concerning the deferred exercisability of the Option.

            IN WITNESS WHEREOF, EXULT, INC. has caused this Addendum to be
executed by its duly-authorized officer as of the Effective Date specified
below.
