EXPLANATORY NOTE

This Amendment No. 1 to Schedule 13D is being filed to reflect the acquisition by Brookfield Property Partners L.P. (“BPY”) of common shares of Brookfield Office Properties Inc. (“BPO”) pursuant to an exchange offer to acquire any or all of the common shares of BPO that it does not currently own (the “Offer”).

Item 3 of this Schedule 13D is hereby supplemented as follows:
