                 Recommended cash Offer for Datamonitor 

      Completion of compulsory acquisition of Datamonitor Shares


On 14 May 2007, Informa announced the terms of a recommended cash offer to be
made by Informa Acquisitions for Datamonitor at a price of 650 pence per
Datamonitor Share. The Offer Document containing details of the offer was posted
to Datamonitor Shareholders on the same day. The Offer was declared
unconditional in all respects on 13 July 2007.

On 31 July 2007, having received acceptances in respect of more than 90 per
cent of the Datamonitor Shares to which the Offer related, Informa Acquisitions
posted a formal notice (the 'Notice') pursuant to section 979 of the Companies
Act 2006 (the 'Act') to each Datamonitor Shareholder who had not yet validly
accepted the Offer. The Notice set out Informa Acquisitions' intention to apply
the provisions of sections 979 to 982 of the Act to compulsorily acquire all
outstanding Datamonitor Shares on the terms of the Offer.

Informa Acquisitions announces that pursuant to those provisions, Informa
Acquisitions has now acquired 100 per cent of the issued share capital of
Datamonitor. The Offer is therefore now closed and no longer capable of
acceptance.

Terms defined in the Offer Document dated 14 May 2007 have the same meanings in
this announcement.
