     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.

     consist of the following and may be changed by a mutual agreement of the
     parties:

          the use of Ragnarok as described in (a) above; and

     this Agreement, such CD-Rom sales shall be included as part of Sunny's
     sales activities as agent for the term of this agreement.

     under any circumstances, sell or service Ragnarok in other territories, and
     shall not exercise its rights over Ragnarok beyond the scope of the rights
     granted herein.

     sales agency agreements for the benefit of GRAVITY.

     Terms of Use on Ragnarok IP Service, and shall be proportional to the

     and conditions, including the Terms of Use on Ragnarok IP Service or the

     case shall be as specified in Article 2, Section 7, Subsection C, of the
