Thomson and Reuters Provide Regulatory Update

he Thomson Corporation (NYSE: TOC; TSX: TOC) and Reuters (LSE: RTR, NASDAQ: RTRSY) today announced that they have agreed with the U.S. Department of Justice (DOJ) to align more closely its regulatory review timetable for Thomson’s proposed acquisition of Reuters with that of the European Commission (EC). The DOJ and EC have been working cooperatively with one another in their reviews. As a result, the DOJ is now expected to render a decision on or about the date on which the EC makes its decision.

Thomson and Reuters have had productive discussions with the DOJ and EC. Given the highly complementary nature of their businesses, the two companies have a high degree of confidence that the acquisition will receive clearance on an expedited timetable.

Thomson and Reuters expect the transaction to close early in the second quarter of 2008. While the regulatory review process continues, integration planning efforts associated with the acquisition are proceeding on course.

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will continue until the date on which the Transaction becomes, or is declared, unconditional, lapses or is otherwise withdrawn or on which the ’offer period’ otherwise ends.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.
