Euro and Dollar IRS Platform - Already Seeing Positive Results

JERSEY CITY/LONDON, October 6,2005- Thomson TradeWeb, part of The Thomson Corporation (NYSE: TOC; TSX: TOC), a leading global provider of integrated information solutions to financial professionals, announced today that TradeWeb's 3rd quarter volume reached $11 trillion across its 13 online marketplaces. This record volume was up 57% over the same period last year and was principally driven by a continued growth in large trades being executed electronically along with more TBA-MBS volume moving online. Approximately 64% of TradeWeb's 3rd quarter volume came from trades of greater than $100 million in size, up from 52% for the same period the previous year. TradeWeb's record results have also been positively impacted by incremental trading volume coming from its new online markets, including Tri-party Repurchase Agreements and Euro- and US dollar-denominated Interest Rate Swaps.

In late October, TradeWeb will be launching its new online market for credit default swap index products. It will provide efficient trade execution and processing for new CDS trades, unwinds and assignments using ISDA's newly released Novation Protocol. It will also provide users with a real-time link with DTCC's Deriv/SERV for accurate and timely trade matching and position management. Ten leading CDS dealers have committed to providing liquidity over TradeWeb's new CDS online marketplace.

Jim Toffey, CEO of Thomson TradeWeb commented, "TradeWeb continues to experience strong growth by providing institutional investors and dealers efficient online markets that enable trade execution and processing for large, small, simple or complex transactions. We also take pride in our ability to bring innovation to the fixed-income markets. For example, with our recent launch of online markets for OTC derivatives, we have built a world-class industry solution that helps buy-side and sell-side firms better manage the complex world of interest rate swap and credit default swap trading and processing."

Lee Olesky, President of Thomson TradeWeb added, "In many respects, TradeWeb is at the beginning of a new phase in its business with expansion into credit markets, OTC derivatives and new geographical regions. Our latest European offering, Euro Interest Rate Swaps, is going from strength to strength and, coupled with the recent addition of US dollar Swaps, has proved a very welcome addition to the platform with our European customers."
