                             STOCK OPTION AGREEMENT

                  The following provisions are hereby incorporated into, and are
hereby made a part of, that certain Stock Option Agreement dated 2~ (the "Option
Agreement") by and between Infoseek Corporation (the "Corporation") and 1~
("Optionee") evidencing the stock option (the "Option") granted on such date to
Optionee under the terms of the Corporation's 1996 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. Should there occur an Involuntary Termination of Optionee's
Service within twelve (12) months following a Corporate Transaction in which the
Option is assumed or replaced, then the Option (or replacement grant), to the
extent outstanding at the time but not otherwise fully exercisable, shall
automatically accelerate so that the Option shall immediately become exercisable
for all the Option Shares at the time subject to the Option and may be exercised
for any or all of those Option Shares as fully vested shares of Common Stock.
The Option shall remain so exercisable until the earlier of (i) the Expiration
Date of the option term or (ii) the expiration of the one (1)-year period
measured from the date of such 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 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
         level of responsibility, (B) a reduction in Optionee's level of
         compensation (including base salary, fringe benefits and participation
         in any corporate-performance based bonus or 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 (or the replacement grant) is to remain
exercisable following the Involuntary Termination of Optionee's Service within
twelve (12) months after the Corporate Transaction in which the Option is
assumed or replaced and shall supersede any provisions to the contrary in
Paragraph 5 of the Option Agreement.
