SAFE HARBOUR STATEMENT:

This   announcement   may   contain   forward-looking   statements,    including
'forward-looking  statements'  within the meaning of the United  States  Private
Securities   Litigation   Reform  Act  of  1995.   Words   such  as   'expects',
'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,  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.
