EXECUTION VERSION

         International Subsidiaries. Company may inform Microsoft that a
         subsidiary that is wholly owned, directly or indirectly, by Company
         will be responsible for the obligations of Company under this Agreement
         with respect to the market served by that wholly-owned subsidiary. Any
         such notification or delegation by Company shall not limit Company's
         obligations and liabilities to Microsoft under this Agreement, and
         Company hereby agrees to guarantee all such obligations and liabilities
         in the relevant market. without limitation of the foregoing, Company
         has informed Microsoft that (i) Overture Ireland, its wholly-owned
         subsidiary, shall be responsible for Company's obligations relating to
         the MSN Search Site in the UK market, the MSN Search Site in Germany,
         the MSN Search Site in France, (ii) Overture Japan, its wholly-owned
         subsidiary, shall be responsible for Company's obligations relating to
         the MSN Search Site in Japan and (iii) Overture Korea, its wholly-owned
         subsidiary, shall be responsible for Company's obligations relating to
         the MSN Search Site in Korea.

8.       A new Section 3.2.3.3 will be added as follows:

         3.2.3.3  Korea. For the twelve-month period beginning May 1, 2003 and
                  ending April 30, 2004 ("Guaranteed Phase for MSN Korea"),
                  Company will pay to Microsoft the greater of (i) the Revenue
                  Share Payment for the MSN Search Site in Korea as set forth in
                  Section 3.2.2 and (ii) the Guaranteed Payment for MSN Search
                  Site in Korea (as defined below).

                  For the purposes of this Section 3.2.3.3, "Guaranteed Payment
                  for the MSN Search Site in Korea" means the [*] (not to exceed
                  the maximum in Table 4, column D) from the MSN Search Site in
                  Korea.

                  If Microsoft fails to deliver the Minimum Queries rendering to
                  the URL http://search.msn.co.kr before April 30, 2004, then
                  the Guaranteed Phase for MSN Korea will extend until all such
                  guaranteed Queries are delivered (the "Guaranteed Phase
                  Extension for MSN Korea"). During the Guaranteed Phase
                  Extension for MSN Korea, Company will not be required to make
                  any additional Guaranteed Payments, but Company will continue
                  to be required to make Revenue Share Payments. Once the
                  Guaranteed Phase for MSN Korea has concluded, Company shall
                  pay Microsoft pursuant to Section 3.2.2 for Gross Revenue from
                  the MSN Search Site in Korea.

                                     Table 4

9.       Section 3.2.4 will be deleted in its entirety and replaced with the
         following:

         3.2.4    Company will make all payments due to Microsoft per Section
                  3.2.1 and 3.2.2 in U.S. Dollars, or other currency as mutually
                  agreed by the parties within forty-five (45) days after the
                  end of each calendar month. All payments will be accompanied
                  by a statement showing in reasonable detail the basis for the
                  payment(s). Company and Microsoft will mutually agree on
                  whether Company will make a single payment for all amounts due
                  hereunder or separate payments for individual markets. The

                  payments relating to the Korea Search Site.

10.      Section 7.2 will be deleted in its entirety and replaced with the
         following:

         7.2      Microsoft Extension Right. Microsoft may - at its sole
                  discretion and in writing - opt to extend the Main Period Term
                  for two (2) additional two-year periods for one or more
                  markets covered by this Agreement; provided that one of the
                  markets is the U.S (English-speaking). The first option to
                  extend ("First Extension") will allow Microsoft to extend the
                  Main Period Term for a two-year period commencing on January
                  1, 2005 and continuing until December 31, 2006, provided
                  Microsoft notifies Company in writing on or before September
                  30, 2004 of its intention to enter into the First Extension.
                  The second option to extend ("Second Extension") will allow
                  Microsoft to extend the Main Period Term for an additional two
                  (2) year period commencing on January 1, 2007 and continuing
                  until December 31, 2008, provided Microsoft notifies Company
                  in writing on or before September 30, 2006 of its intention to
                  enter into the Second Extension. In order for Microsoft to
                  exercise the Second Extension, Microsoft must have exercised
                  the First Extension for the same MSN Search Site(s). If
                  Microsoft elects to extend the Main Period Term according to
                  this Section 7.2, the percentage of revenue Company pays to
                  Microsoft will be determined by Section 3.2.1 and 3.2.2.

Defined terms herein have the same meaning as set forth in the Agreement, except
as otherwise provided.
