THOMSON AND REUTERS PROVIDE REGULATORY UPDATE

EC confirms that its regulatory review will proceed to Phase 2

Timing agreement signed with the U.S. Department of Justice

Technical amendment signed to reflect U.S. regulatory review process

STAMFORD, Conn., LONDON, October 8, 2007 — The Thomson Corporation (NYSE: TOC; TSX: TOC), and Reuters (LSE: RTR, NASDAQ: RTRSY) today provided an update on the ongoing European and U.S. regulatory processes related to Thomson’s proposed acquisition of Reuters.

The European Commission (EC) has informed the two companies that it will proceed to a Phase 2 review of the proposed transaction to give it more time to examine the transaction and its impact on the competitive environment.  Competitive conditions in the industry where Thomson Financial and Reuters operate are complex and constantly evolving.  Both companies will continue to work with the EC to help narrow and resolve the issues which the EC has indicated require further review.  The companies currently anticipate that the Phase 2 review will be completed during the first quarter of 2008.

In the U.S., the two companies have signed a timing agreement with the Department of Justice related to its regulatory review. Under the timing agreement, the Department of Justice will provide Thomson and Reuters with a decision by January 15, 2008.

Thomson and Reuters also announced that they have agreed to a technical amendment related to the U.S. regulatory pre-condition described in their announcement of May 15, 2007.  The purpose of the amendment is to reflect the actual review procedure being conducted by the Department of Justice and the companies’ original intent in drafting the U.S. regulatory pre-condition.  For technical reasons related to the dual listed company (DLC) structure contemplated for Thomson-Reuters, the transaction is not subject to the filing and waiting period requirements of the U.S. Hart-Scott-Rodino Antitrust Improvements Act of 1976 as had been contemplated and reflected in the original wording of the U.S. regulatory pre-condition. As previously announced, the Department of Justice has been conducting a review of the transaction similar to a Hart-Scott-Rodino review, as is common for a transaction of this size.

Commenting on these regulatory developments, Tom Glocer, currently CEO of Reuters and CEO designate of Thomson-Reuters said, “Today’s developments bring clarity and transparency to the regulatory timetables on both sides of the Atlantic.  Our discussions with both sets of regulators have been constructive and have developed in line with our expectations. Thomson and Reuters remain committed to working with them through to the end of their investigations.  Customer feedback to the proposed transaction has been overwhelmingly positive, and we are hopeful that we can work with the regulators to expedite the process and complete the transaction in or around the first quarter of 2008.”

Richard J. Harrington, President and CEO of The Thomson Corporation, added, “We continue to believe a combined Thomson-Reuters will enhance competition as well as customer value.”

The text of the revised pre-condition related to the U.S. regulatory review is attached to this news release.

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.
