JERSEY CITY, NJ (October 4, 2004) - Thomson TradeWeb, a unit of The Thomson Corporation (NYSE:TOC; TSX: TOC), announced today that Barclays Capital has started providing liquidity in TBA-MBS securities for its customers over TradeWeb, the leading dealer-to-customer online market for fixed-income. Barclays Capital, the investment banking division of Barclays Bank Plc., is an active market maker in seven additional TradeWeb marketplaces including U.S. Treasuries, European governments, Agencies, Agency Discount Notes, ECP, Pfandbriefe, and Supras. Over the past quarter, Barclays Capital has consistently ranked among the Top 3 dealers in TradeWeb Treasury volume market share.

In joining TradeWeb TBA-MBS, Barclays Capital extends its reach into the residential mortgage pass-through market, where more than 350 major institutional investors use TradeWeb to access the liquidity of 17 dealers and trade more than $36 billion in volume each day. Other members of TradeWeb's TBA-MBS dealer group Credit Suisse First Boston, Goldman Sachs, Lehman Brothers, Merrill Lynch, Citigroup, Morgan Stanley, Deutsche Bank, JPMorgan, Greenwich Capital, ABN AMRO, Bear Stearns, UBS Investment Bank, Banc of America Securities, Countrywide Securities, Freddie Mac SSandamp;TG, and Wachovia Securities.

Tom Hamilton, Managing Director and Head of Mortgage Trading at Barclays Capital, added, "Barclays Capital is strongly committed to delivering high quality services and liquidity for mortgage investors and our participation on TradeWeb TBA-MBS helps in achieving these objectives."

TradeWeb TBA-MBS has rapidly transformed the TBA-MBS mortgage marketplace.
