Dear Sirs:
We hereby inform that, on the present date, I filed a request for arbitration before International Chamber of Commerce - ICC against Casino Guichard Perrachon, Segisor and Sudaco Participações Ltda. (jointly "Casino"), in accordance with the Shareholders' Agreeement dated as of November 27th, 2006 ("Shareholders' Agreeement").
The arbitration procedure, which is subject to applicable confidentiality provisions, is aimed at ensuring that Casino complies with the Shareholders' Agreement and refrain from further actions that violate the rights and obligations of my position as Chairman of the Board of Directors.
I will keep the Company informed of any deployment related to it. I require to the company's management, if it is the case, to publicly disclose the entire content of this letter to the market.
Sincerely,
Abilio dos Santos Diniz
