                                BY AND BETWEEN
                              TRANS COSMOS, INC.

RECITALS

1.  Primus and TCI are parties to a certain Joint Venture Agreement ("JVA")

4.  Pursuant to the First Amendment, Best Career KK was added as a party to the
JVA and was issued 500 shares of stock in Primus KK. Best's shares were

shares.  TCI currently owns 85.7% of the stock of Primus KK and Primus owns
14.3% of such stock.

Amendment, TCI shall cause Primus KK to transfer 5% of TCI's interest in Primus

                                                                               1
