                                               November 5, 2008


Citibank, N.A.
ADR Department
388 Greenwich Street
New York, New York 10013

Ladies and Gentlemen:

      We have acted as U.S. counsel to Citibank, N.A. (the "Depositary") in
connection with the registration on Form F-6 (the "Registration Statement")
under the Securities Act of 1933 (the "Securities Act"), of American depositary
shares ("ADSs") evidenced by American depositary receipts ("ADRs"), each ADS
representing the right to receive one-fifth of one fully paid share of common
stock (the "Shares") of Ubisoft Entertainment SA, a company incorporated under
the laws of France (the "Company").

      Subject to any provision of French law or regulation and the terms of the
Shares, we advise you that, when the Shares have been legally issued, we are of
the opinion that the ADSs, when issued in accordance with the terms of the ADRs
and the Registration Statement, will be legally issued and will entitle the
registered holders of the ADSs to the rights specified in the applicable ADRs.

      The foregoing opinion is limited to the laws of the State of New York and
the federal laws of the United States of America. We are expressing no opinion
as to the laws of any other jurisdiction.

      We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement. In giving such consent, we do not thereby admit that we
come within the category of persons whose consent is required under Section 7 of
the Securities Act.

                                                 Very truly yours,


                                                 /s/ Thacher Proffitt & Wood LLP
