This   announcement   may   contain   forward-looking   statements,    including
'forward-looking  statements'  within the meaning of the United  States  Private

'anticipates',  'intends'  or the  negative  of these  terms and  other  similar
expressions of future performance or results,  including financial objectives to
2010,  and  their  negatives  are  intended  to  identify  such  forward-looking
statements. These forward-looking statements are based upon current expectations
and assumptions regarding  anticipated  developments and other factors affecting
the Group.  They are not  historical  facts,  nor are they  guarantees of future
performance.   Because  these  forward-looking   statements  involve  risks  and
uncertainties,  there are important  factors that could cause actual  results to
differ  materially  from those  expressed  or  implied by these  forward-looking
statements,   including,  among  others,  competitive  pricing  and  activities,
consumption  levels,  costs,  the  ability to maintain  and manage key  customer
relationships  and supply chain sources,  currency  values,  interest rates, the
ability to integrate acquisitions and complete planned divestitures, the ability
to complete  planned  restructuring  activities,  physical risks,  environmental
risks,  the  ability to manage  regulatory,  tax and legal  matters  and resolve
pending  matters within current  estimates,  legislative,  fiscal and regulatory
developments,  political,  economic  and  social  conditions  in the  geographic
markets  where the Group  operates and new or changed  priorities of the Boards.
Further  details of potential  risks and  uncertainties  affecting the Group are
described  in the  Group's  filings  with the London  Stock  Exchange,  Euronext
Amsterdam and the US Securities  and Exchange  Commission,  including the Annual
Report & Accounts on Form 20-F. These  forward-looking  statements speak only as
of the date of this  announcement.  Except as required by any  applicable law or
regulation,  the Group  expressly  disclaims any  obligation or  undertaking  to
release  publicly  any updates or revisions  to any  forward-looking  statements
contained herein to reflect any change in the Group's  expectations  with regard
thereto or any change in events,  conditions or  circumstances on which any such
statement is based.
