         Re:      Registration Statement on Form S-8

Dear Sirs,

We have examined the Registration Statement on Form S-8 to be filed by you with
the Securities and Exchange Commission on or about April 5, 2001 (the
"Registration Statement"), in connection with the registration under the
Securities Act of 1933, as amended, of 3,500,000 additional ordinary shares
(which will be represented by 3,500,000 American Depositary Shares of the
Company) in the capital of the Company reserved for issuance under the 1996
Supplemental Stock Plan (the "1996 Plan") (the "Shares").

As your legal counsel, we have examined the 1996 Plan and are familiar with the
proceedings proposed to be taken by you in connection with the issuance of the
Shares under the 1996 Plan.

It is our opinion that the Shares will be, if issued in the manner referred to
in the 1996 Plan, on application by the Optionees under the said Plan for the
Shares and pursuant to the respective agreements that accompany the Plan,
legally and validly issued and fully paid.

We consent to the use of this opinion as an exhibit to the Registration
Statement on Form S-8 and further consent to the use of our name, wherever
appearing in the said Registration Statement, including any Prospectus
constituting a part thereof and any amendments thereto.

Yours faithfully,

/s/ BINCHYS
