Company Limited.

         The Joint Venture Agreement is hereby amended ax follows:

         Section 3.3 of the Joint Venture Agreement

         Whereas WTSCO has agreed to contribute to the JVC "2 MMIS channels
within Bangkok of at least 8 MHz of bandwidth each separated by at least 16 MHz
of bandwidth" it has now been determined that. the 16 MHz separation may not be
enough to utilize the equipment to be supplied by WLGS.

         Should it be determined by WLGS, that for technical reasons, the
bandwidth separation must be no less than 36 MHz, WTSCO shall replace one or
both of the MMDS channels to ensure a separation of at least 36 MHz.

         Any reasonable costs associated with this change shall be home
initially by WLGS subject to repayment under Article 6 of the Joint Venture
Agreement. regarding profit distribution.

         This Addendum shall take effect immediately when signed by both parties
and shall be attached to the Joint Venture Agreement and be made a part thereof.

Agreed and Accepted:
WTSCO                                           Witness
