The directors of Thomson accept responsibility for the information
contained in this announcement. To the best of the knowledge and belief of
the directors of Thomson (who have taken all reasonable care to ensure such
is the case), the information contained herein for which they accept
responsibility is in accordance with the facts and does not omit anything

DEALING DISCLOSURE REQUIREMENTS

Under the provisions of Rule 8.3 of the Takeover Code (the 'Code'), if
any person is, or becomes, 'interested' (directly or indirectly) in 1% or
more of any class of 'relevant securities' of Thomson or of Reuters, all
'dealings' in any 'relevant securities' of that company (including by means
of an option in respect of, or a derivative referenced to, any such 'relevant
securities') must be publicly disclosed by no later than 3.30 pm (London
time) on the London business day following the date of the relevant
transaction. This requirement will continue until the date on which the
acquisition of Reuters becomes, or is declared, unconditional, lapses or is
otherwise withdrawn or on which the 'offer period' otherwise ends. If two or
more persons act together pursuant to an agreement or understanding, whether
formal or informal, to acquire an 'interest' in 'relevant securities' of
Thomson or Reuters, they will be deemed to be a single person for the purpose
of Rule 8.3.

Under the provisions of Rule 8.1 of the Code, all 'dealings' in 'relevant
securities' of Thomson or Reuters by Thomson or Reuters, or by any of their
respective 'associates', must be disclosed by no later than 12.00 noon
(London time) on the London business day following the date of the relevant
transaction.

A disclosure table, giving details of the companies in whose 'relevant
securities' 'dealings' should be disclosed, and the number of such securities
in issue, can be found on the Takeover Panel's website at
www.thetakeoverpanel.org.uk. 'Interests in securities' arise, in summary, 
when a person has long economic exposure, whether conditional or absolute, to 
changes in the price of securities. In particular, a person will be treated 
as having an 'interest' by virtue of the ownership or control of securities, 
or by virtue of any option in respect of, or derivative referenced to, 
securities.

Terms in quotation marks are defined in the Code, which can also be found
on the Panel's website. If you are in any doubt as to whether or not you are
required to disclose a 'dealing' under Rule 8, you should consult the Panel.
