JERSEY CITY/LONDON, July 11, 2005 - Thomson TradeWeb, part of The Thomson Corporation (NYSE: TOC; TSX: TOC), a leading global provider of integrated information solutions to professional customers, announced today that TradeWeb's 2nd quarter volume for its 12 online marketplaces surpassed $10.3 trillion - up a remarkable 63% from the same period last year. This growth spanned multiple marketplaces and was principally driven by customers executing larger-sized trades online. Approximately 62% of TradeWeb's 2nd quarter volume came from trades of greater than $100 million in size, up from 50% for the same period last year.

Jim Toffey, CEO of Thomson TradeWeb said, "Our results clearly demonstrate that institutional investors and dealers around the globe have become accustomed to executing very large trades electronically. We expect this trend to continue as market professionals become more aware of the speed, efficiency, and superior price discovery that TradeWeb provides for trades of any size. Electronic trading has become a natural evolutionary step in the development of efficient markets."

Lee Olesky, President of Thomson TradeWeb added, "While TradeWeb continues to build significant momentum in its most mature liquid markets, such as European Governments, it is also leading the way in developing online marketplaces for derivatives and expanding its franchise internationally."
