Piedade was elected as Sonae's Executive Director (Chief Development Officer).
In light of this change, Joao Nonell Günther Amaral announced his resignation as
member of the Company's Board of Directors.

This notice, including the resolution proposals to be considered at the
Extraordinary General Meeting, are based on a request by the Company's
shareholder Flybird Holding Oy ("Flybird Holding"), a company controlled by
