2.	I irrevocably and unconditionally consent to (and shall procure that each of  my Related Persons irrevocably and unconditionally consents to):

(a)

the inclusion of references to me, and particulars of this undertaking and my or, if applicable, my Related Persons legal and beneficial holdings of relevant securities of the Company in the Scheme Press Announcement and any Scheme Document or in a press announcement in relation to Offer (the “Offer Press Announcement”) and any Offer Document, and any other announcement made, or document issued, by or on behalf of the Bidder or the Company in connection with the Acquisition; and

(b)

include any new, increased or revised scheme of arrangement or offer for the acquisition by Bidco of all of the issued and to be issued share capital of the Company (other than that already owned by Bidco or any entity in the same group as the Bidder).
