The Company wishes to advise shareholders that section 1.9 of the Initial Announcement stating that all conditions precedent relating to the Acquisition had been met, was not correct. Accordingly shareholders are advised that there remains one outstanding condition precedent prior to finalising the Acquisition: • an exemption from the Takeover Regulation Panel (“TRP”) for the Acquisition to be exempted from the application of the provisions of Part B and Part C of the Companies Act and the Takeover Regulations or, to the extent that such exemption cannot be obtained, the approval of the TRP being obtained for the implementation of the Acquisition; The Company is confident that this condition precedent will be met timeously.
