(1)  The Republic of Finland ("Finland");

     and

(2)  The Kingdom of Sweden ("Sweden").

WHEREAS, Finland and Sweden entered into the Shareholders' Agreement, dated as

certain matters relating to the merger of Telia AB and Sonera Corporation;

WHEREAS, Finland and Sweden now desire to make certain amendments to the
Agreement;

NOW, THEREFORE, the parties hereto hereby agree as follows:

1.   The following definition is added to Section 1:

     "TeliaSonera" means TeliaSonera AB (publ).

2.   Section 4.1.2(ii) of the Agreement is hereby replaced by the following:

     "Carl Bennett, a current member of the Board of Directors of TeliaSonera,
     shall be appointed, and shall serve as, Deputy Chairman of the Board of
     Directors of TeliaSonera at least until the closing of the Annual General
     Meeting of shareholders of TeliaSonera to be held in 2005";

3.   The proviso following directly after Section 4.1.2(v) of the Agreement is
     hereby replaced by the following:

     "provided, however, that, in connection with the Annual General Meeting of
     shareholders of TeliaSonera to be held in 2003, one (1) of the members
     referred to in subparagraph (iv) above shall be replaced with one (1) new
     independent member who is currently not a member of the Board of Directors
     of Sonera or the Board of Directors of Telia to be nominated by the new
     Nomination Committee of TeliaSonera in accordance with Section 4.1.3., who
     shall serve at least until the closing of the General Meeting of
     shareholders of TeliaSonera to be held in 2004"

     The remnant of the proviso following directly after Section 4.1.2(v), from
     "and provided..." to "the requirements of Section 4.1.1." shall remain
     unchanged.

4.   Finland and Sweden hereby acknowledge and agree that except as specifically
     supplemented and amended, changed or modified hereby, the Agreement shall
     remain in full force and effect in accordance with its terms.

5.   This Amendment shall be governed by and construed in accordance with the
     substantive laws of Sweden. Any dispute, controversy or claim concerning
     the validity, scope, meaning, construction, application or effect of this

     Finnish Central Chamber of Commerce. Each party to this Amendment shall
     appoint one arbitrator and the two arbitrators shall appoint a third
