                                FIRST AMENDMENT
                                       TO
            SERIES A PREFERRED STOCK SUPPLEMENTAL PURCHASE AGREEMENT


Preamble

         This First Amendment to Series A Preferred Stock Supplemental Purchase
Agreement (this "First Amendment") is made as of the 18th day of March, 1996
(the "Effective Date"), by and between Infoseek Corporation, a California
corporation (the "Company"), and the Applied Computing Systems Institute of
Massachusetts, Inc., a tax exempt charitable Massachusetts corporation
("Investor").  This First Amendment amends the Series A Preferred Stock
Supplemental Purchase Agreement (the "Original Agreement") which the Investor
and the Company made as of the 22nd day of July, 1994.  All capitalized terms
not specifically defined in this First Amendment are as defined in the Original
Agreement.

Recital

         Based upon intervening events since the Original Agreement, the
Investor and the Company desire to provide that the Investor shall retain
one-half of the Shares and shall forfeit the other one-half of the Shares.  The
Investor and the Company desire to instruct the Escrow Agent accordingly.
Investor and the Company are concurrently amending the License to reduce the
royalty rate on certain gross revenues and to make corresponding changes
concerning the vesting of the Shares.

Agreement

         Based upon the premises contained in the above Recital, and the mutual
promises below, the Company and the Investor hereby agree as follows:

         The Investor and the Company hereby agree that the Initial Shares
shall be deemed to have vested as of January 1, 1995, and that the Secondary
Shares shall be deemed as of the Effective Date to never vest and therefore
will be returned free of charge to the Company.  However, the Company agrees
that for purposes of calculating the number of Series E Preferred shares which
the Investor may purchase pursuant to exercise of Investor's "Participation
Right" granted pursuant to the Amended and Restated Investors' Rights Agreement
dated May 4, 1995, the Investor shall be deemed to own 746,316 rather than
373,158 Series A Preferred shares.  The Investor has executed and delivered to
the Company, who has delivered to the Escrow Holder, the Attachment A
Assignment Separate From Certificate to effect the return of the Secondary
Shares.  As a result, the Investor and the Company hereby instruct the Escrow
Holder to mail the share certificate representing the Initial Shares to the
Investor and to mail the share certificates representing the Secondary Shares
to the Company to cancel.  Thus, the Investor and the Company confirm and agree
that the entire

equity interest of the Investor in the Company as of the Effective Date
consists of 373,158 shares of Series A Preferred Stock: however, the Investor's
Participation Right for purposes of the Company's Series E Preferred Stock
financing shall continue to be calculated as if the Investor's equity ownership
remained at 746,316 shares of Series A Preferred Stock.  The Investor and the
Company hereby release the Escrow Holder for its actions to date in maintaining
possession of the Initial and Secondary Shares. As a result of the foregoing,
the Investor and the Company hereby agree that Sections 1.3 and 6.2 are deleted
from the Original Agreement as of the Effective Date as is the second sentence
of Section 7.10.

         This First Amendment constitutes the entire agreement between the
parties with respect to its subject matter and supersedes all prior or
concurrent agreements between the parties, written or oral, regarding its
subject matter.  Except as amended by this First Amendment, the Original
Agreement remains in full force and effect.  The parties are concurrently
entering into an amendment to the License to alter the royalty rate and to make
changes to correspond to this First Amendment regarding the Shares and the
Investors Rights Agreement has been amended subsequent to the date of the
Original Agreement.  This First Amendment shall be governed by California law.
Any dispute arising under this First Amendment shall be subject to arbitration
as provided in Section 15 of the License.

Authorized Signatures

         For purposes of binding the parties to the terms and conditions of
this First Amendment to Series A Preferred Stock Supplemental Purchase
Agreement, duly authorized representatives of the parties have signed their
names as of the date first above written.
