     12, 2002, GRAVITY owns the rights over Ragnarok, and shall appoint Sunny as
     its agent for conducting the domestic sales of Ragnarok.

2.   The Original Agreement shall take precedence over all the terms and
     conditions set out in the Marketing Agreement dated December 19, 2001. The
     Original Agreement, however, shall take precedence over this Agreement only
     in case of conflicts and contradictions therewith.
