      Re:   American Depositary Receipts for Common Shares of Digiwave
            Technologies Inc.
            --------------------------------------------------------------------

Ladies and Gentlemen:

      We refer to the  registration  statement to be filed on Form F-6 under the
Securities  Act of 1933  (the  "Registration  Statement")  by the  legal  entity
created by the  agreement  (the  "Deposit  Agreement")  for issuance of American
Depositary Shares ("ADSs")  evidenced by American  Depositary  Receipts ("ADRs")
for common shares of Digiwave Technologies Inc., for which you propose to act as
Depositary.

      We are of the opinion that the ADSs covered by the Registration Statement,
when issued in accordance  with the terms of the Deposit  Agreement,  will, when
sold,  be legally  issued and will  entitle  the  holders  thereof to the rights
specified in the Deposit Agreement and the ADRs.

      This  opinion  may  be  used  by  you as an  exhibit  to the  Registration
Statement.

                                               Very truly yours,

                                               /s/ Emmet, Marvin & Martin LLP
                                               ------------------------------
