                                    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 Ask Jeeves, Inc. (the "Corporation") and
____________________________ ("Optionee") evidencing the stock option (the
"Option") granted this day to Optionee under the terms of the Corporation's 1999
Equity Incentive Plan, and such provisions are 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/AUTHORIZED RESIGNATION FOLLOWING
                     CHANGE IN CONTROL/BUSINESS SEGMENT SALE

        1. To the extent the Option is to be assumed or otherwise continued in
effect in connection with a Change in Control or Business Segment Sale, the
Option shall not, upon the occurrence of that Change in Control or Business
Segment Sale, accelerate as to any of the shares at the time subject to the
Option (the "Option Shares"), and the Option shall accordingly continue, over
Optionee's period of Continuous Service following such Change in Control or
Business Segment Sale, to vest and become exercisable for those Option Shares in
one or more installments in accordance with the normal vesting schedule for the
Option set forth in the Option Agreement (the "Vesting Schedule"). However,
immediately upon an Involuntary Termination of Optionee's Continuous Service
within twelve (12) months following such Change in Control or Business Segment
Sale or an Authorized Resignation in connection with such Change in Control or
Business Segment Sale, Optionee shall, for purposes of such Vesting Schedule, be
credited with an additional twelve (12) months of Continuous Service so that the
Option, to the extent not otherwise fully vested and exercisable for all the
Option Shares, shall become immediately exercisable for that additional number
of Option Shares equal to the incremental number of shares for which the Option
would have vested and become exercisable in accordance with the Vesting Schedule
had Optionee completed an additional twelve (12) months of Continuous Service at
the time of his or her Involuntary Termination or Authorized Resignation. In no
event, however, shall the number of Option Shares for which the Option vests and
becomes exercisable on such an accelerated basis exceed the number of shares as
to which the Option is not otherwise actually vested and exercisable, in
accordance with the Vesting Schedule, immediately prior to the effective date of
such Involuntary Termination or Authorized Resignation.

        2. The Option as accelerated pursuant to this Addendum shall remain so
exercisable until the earlier of (i) the expiration date of the Option set forth
in the Option Agreement or (ii) the sooner termination of the Option in
accordance with the applicable provisions of the Option Agreement or Section 11
of the Plan.

        immediately thereafter beneficially owned, directly or indirectly and in
        substantially the same proportion, by the persons who beneficially owned

        such transaction;

                        (B) any stockholder-approved sale, transfer or other

        to the elections of Board members) outstanding immediately after the
        consummation of such transaction or series of related transactions,
        whether such transaction involves a direct issuance from the Corporation

for purposes of this Agreement, to constitute grounds for termination for
