WHEREAS, Licensor and Licensee ("Parties" collectively) entered into an
Exclusive Ragnarok Online License and Distribution Agreement ("The Agreement"),
dated June 13th, 2002.

WHEREAS, Parties to the Agreement now desire to amend the Agreement as specified
below.

NOW, THEREFORE, the parties agree as follows:

1.       EXTEND THE TERM OF THE AGREEMENT:

         Parties agreed to extend the Agreement for Two(2) years ("Renewed
         Term") from the expiration date with conditions stated below in this
         Amendment. The newly extended term of the Agreement shall be from March
         4th, 2005 to March 4th, 2007.

2.       TERMS AND CONDITIONS:

         (1)      Licensee shall pay One Million United States Dollars
                  (US$1,000,000) to Licensor as License Extension Fees. The
                  License Extension Fees shall be paid in four(4) equal parts
                  according to the following schedule:

                  US$250,000 payable on December 1st, 2004

                  US$250,000 payable on September 1st, 2005

         In case the Agreement is extended beyond March 4th, 2007, it is
         understood that License Extension Fee will be waived.

         (2)      Licensee agrees to increase the Royalty rate ("New Royalty")
                  from Thirty(30%) percent of the Service-Sales Amount (as
                  defined in Article 1.12 and Article 5.1 of the Agreement) to
                  Thirty-Five (35%) percent of the Service-Sales Amount. The New
                  Royalty will be effective from March 4th 2005 to March 4th,
                  2007.

                  In case the Agreement is extended beyond March 4th, 2007, it
                  is understood that Royalty rate, Thirty-Five (35%) percent of
                  the Service-Sales Amount, will not be changed.

         (3)      No later than three (3) months prior to the expiration of
                  Renewed Term specified on this Amendment, Licensor shall give
                  Licensee the first right of negotiation for a period of thirty
                  (30)days for an extension of Agreement for an additional term
                  ("Extended Term") for the Game. The additional extension shall
                  be on the same terms and conditions as stated above (Article
                  2.1 and Article 2.2). If no agreement in writing is made
                  between the Parties for renewal or re-execution of a license
                  agreement after such negotiation period, this Agreement shall
                  expire without any further extension or renewal.

IN WITNESS WHEREOF, the Parties have executed this Amendment the day and year
first above-written.

GRAVITY CORPORATION,                     ASIASOFT INTERNATIONAL COMPANY LIMITED.
