Thomson and Reuters Receive Regulatory Clearance

Acquisition Expected to Close week of April 13, 2008

STAMFORD, Conn., LONDON, February 2008 - The Thomson Corporation (NYSE: TOC; TSX: TOC) and Reuters (LSE: RTR, NASDAQ: RTRSY) today announced that the European Commission (EC), US Department of Justice (DOJ) and Canadian Competition Bureau (CCB) have given approval for Thomson’s proposed acquisition of Reuters.

In order to obtain clearance, Thomson has agreed to sell a copy of the Thomson Fundamentals (Worldscope) database and Reuters has agreed to sell a copy of the Reuters Estimates, Reuters Aftermarket Research and Reuters Economics (EcoWin) databases. The sales include copies of the databases, source data and training materials, as well as certain contracts and employees connected to the databases.

Thomson and Reuters retain full ownership of the relevant databases and these undertakings do not affect Thomson’s and Reuters ongoing business or capabilities in these areas. The two companies are not required to complete the sales prior to the closing of the acquisition. All regulatory approvals needed to close the transaction have now been obtained.

Thomson and Reuters will each now seek shareholder and court approvals. The companies expect the transaction to close the week of April 13, 2008.

Tom Glocer, currently CEO of Reuters and CEO designate of Thomson Reuters, said: “This is an important step toward completing the transaction and creating what we believe will be the leading provider of information and related applications to businesses and professionals around the world.”

Richard J, Harrington, President and CEO of The Thomson Corporation, said: “We were pleased to receive regulatory approval on both sides of the Atlantic today. Our constructive discussions with the EC, DOJ and CCB, and their subsequent approvals reflect the thorough understanding the regulators gained of our businesses and the industries we operate in.”

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 Transaction 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.
