ARTICLE 11. (ASP SERVICE STANDARDS)

<PAGE>

     1.   In providing the ASP Service, WTC shall satisfy the ASP Service
          Standards requested by SKT with respect to the following items:

          (1)  Lag time in the searching or downloading of the calling tone data
               through mobile phones.

          (2)  Lag time in connecting to the website.

          (3)  Lag time in transmitting a Message.

          (4)  Downtime in the ASP Service due to the ASP Service System.

     2.   The specific numerical criteria relating to the items set forth in
          clause 1 shall be proposed by SKT and determined by the mutual
          agreement of the Parties.

     3.   If WTC fails to satisfy the ASP Service Standards set forth in clause
          1, SKT may request remedial measures. Within 15 days of receiving such
          request, WTC shall perform such measures absent a special reason and
          shall promptly give written notice to SKT as to the result of such
          measures. If the failure to satisfy the ASP Service Standards is due
          to WTC's negligence or intentional act, such notice by WTC shall not
          serve to hold WTC harmless from its liabilities.

                               OF THE ASP SERVICE

          the ASP Service System, SKT shall pay the ASP Service Fee to WTC on a
          monthly basis, as set forth in clause 3.

     2.   The Parties shall not compute the ASP Service Fee until May 31, 2002.

          writing the ASP Service Fee based on the criteria set forth in the
          following table.

[__] = MATERIAL OMITTED: CONFIDENTIAL TREATMENT HAS BEEN REQUESTED AND FILED
SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION.

<PAGE>

     4.   WTC hereby acknowledges that the Fixed Charge, which serves as the
          basis for computing the Application Service Fee, is not based upon the
          amount SKT charges the COLORing Service Subscriber, but upon the
          amount SKT collects from the COLORing Service Subscriber. WTC further
          acknowledges that SKT will not include those COLORing Service
          Subscribers that do not pay the Fixed Charge in the computation of the
          ASP Service Fee. In the case of any difference in the amount of the
          ASP Service Fee as computed by each Party, the amount of the ASP
          Service Fee computed by SKT shall be controlling if the difference is
          less than 10%. If the difference is more than 10%, the amount of the
          ASP Service Fee shall be determined by mutual agreement of the
          Parties.

ARTICLE 13. (PAYMENT METHODS FOR THE ASP SERVICE FEE AND DISPUTE RESOLUTION)

     1.   SKT shall provide to WTC in each month data collected from SKT's
          billing system relating to the ASP Service Fee. By the tenth day of
          the following month, WTC shall submit to SKT an invoice for the
          Application Service Fee, together with its official opinion as to
          SKT's billing data and computation. The invoice shall be in a format
          mutual agreed by the Parties.

     2.   If there is no dispute as to the billing data, SKT shall, within 14
          days following the receipt of the invoice described in clause 1, pay
          the Application Service Fee to WTC.

     3.   If there is a dispute as to the billing data described in clause 1,
          SKT may, within 14 days following the receipt of the invoice, demand
          that WTC provide an explanation or data comparison. WTC shall, within
          15 days following the receipt of such notice, provide a written
          explanation or data comparison.

     4.   In the case of the preceding clause, SKT shall not be responsible for
          any liability arising from the delay in performing its payment
          obligation with respect to the Application Service Fee.

ARTICLE 14. (TRIAL COLORING SERVICE)

     Following mutual agreement with WTC, SKT may provide a trial COLORing
     Service for a limited time. The ASP Service Fee shall not be computed
     during this time period.

          Party may terminate this Agreement.

               liquidation, workout, composition, corporate restructuring or
               bankruptcy.

          (2)  Either party becomes unable to properly perform its obligations
               hereunder due to becoming subject to enforcement proceedings such
               as provisional seizure, seizure, provisional disposition or
               auction.

          (3)  Either party becomes unable to properly perform its obligations
               hereunder due to law, court order or governmental order.

ARTICLE 17. (POST-EFFECTIVE PERIOD)

               If this Agreement expires or terminates in accordance with

          post-effective period of six (6) months from the date of such expiry
          or termination and may renew the effective period for one time up to
          additional six (6) months. During the post-effective period, WTC must
          continue to provide the ASP Service, and computation of the ASP
          Service Fee as set forth in Article 12 shall continue to be effective.
