FOR IMMEDIATE RELEASE

Nine Global Dealers and Thomson Financial Form Premier

Electronic Trading Venture Using TradeWeb

STAMFORD, CT, October 11, 2007 — Thomson Financial, an operating unit of The Thomson Corporation (TSX: TOC, NYSE: TOC) and the parent company of TradeWeb,  today announced it plans to form a strategic partnership with nine of the world’s leading global dealers to drive the expansion of electronic trading using the TradeWeb platform. TradeWeb is the world’s leading multi-dealer-to-customer marketplace for fixed income and derivatives linking 35 leading dealers, including the nine investors, with over 2,200 buy-side customers.

The partnership will utilize TradeWeb’s established market position to create a global multi-asset class execution venue for clients. Under the terms of the agreement, the dealers will invest approximately $180 million to purchase a minority stake in TradeWeb’s established markets. Separately, Thomson and the dealers will fund additional investment in asset class expansion.

As part of the overall partnership, Thomson Financial will contribute its equity trading-related assets, including AutEx and the Thomson Order Routing network to TradeWeb.  AutEx is an industry leader in providing equity indications of interest (“IOIs”). Thomson Order Routing is a leading global FIX network, with more than 6,000 connections to over 700 customers around the world.

The dealers that have agreed to invest in TradeWeb are: Credit Suisse, Deutsche Bank, Goldman Sachs, JPMorgan, Lehman Brothers, Merrill Lynch, Morgan Stanley, The Royal Bank of Scotland, and UBS. All nine firms have committed to participate in TradeWeb’s markets, including interest rate swaps, providing a significant opportunity for institutional investors to benefit from the efficiencies of electronic trading.

This deal is expected to provide a number of advantages to clients, including:

—The opportunity to create a unified platform for the trading of fixed income, derivatives and equities markets;

—Integrated multi-asset class trade processing;

—Access to a deep pool of dealer liquidity for interest rate swaps;

—Accurate pricing information off which to drive analytics and modeling;

—True multi-asset and cross-asset class trading, enabling clients to execute advanced trading strategies that are now becoming commonplace, especially with hedge funds and other leveraged investors; and

—Greater market transparency, increased trading effectiveness and reduced operational complexity for both the buy-side and sell-side.

Under the terms of the agreement, Thomson Financial will become a preferred distributor of TradeWeb’s market data.

“This new venture is a demonstration of Thomson Financial’s commitment to working with its dealers and customers to drive performance,” said Sharon Rowlands, CEO of Thomson Financial. “It will marry TradeWeb’s proven technology and operational skills with the support of a world-class group of dealers to provide global, one-stop trading and straight-through processing for our customers.”

TradeWeb was acquired by Thomson Financial in 2004, a year in which trading volumes totaled $26.2 trillion. Since then trading has continued to increase, with clients executing more than $51.2 trillion in trades in 2006, an increase of 95% over 2004. Trading in the first half of 2007 reached $30.6 trillion, a year-on-year increase of 22%.

“This partnership is a natural step forward in the evolution of the online financial marketplace, taking us closer to the time when almost all trading is electronic,” said Jim Toffey, CEO of Thomson TradeWeb. “TradeWeb is ideally positioned to seize this opportunity, and expand e-trading for our clients on one platform through organic growth and through acquisition. The end-game is to be the leading global network where markets meet.”

“At this stage in the evolution of the electronic markets, especially interest rate swaps, the partnership of leading dealers with TradeWeb’s global distribution and technology, is a powerful combination. New investment by the dealers, and ongoing support from Thomson, position us uniquely to continue to work with the wider buy-side and sell-side community to expand our business,” said Lee Olesky, President of Thomson TradeWeb.

Toffey, Olesky, and Billy Hult, Managing Director and Head of U.S. Markets, will retain the same positions in the new venture.

“The dealers are pleased to partner with TradeWeb to provide our clients with the transparency, price discovery and efficiency of electronic execution,” said Vic Simone, Global Head of Principal Strategic Investments for Goldman Sachs, on behalf of the dealer consortium. “Together, we will provide new solutions that reduce technology complexity, increase settlement accuracy and drive best-execution pricing.”

The transaction is expected to close in the next few months, pending regulatory approval.  TradeWeb will maintain its global headquarters in Jersey City, NJ. Average daily trading volume on TradeWeb exceeds $250 billion.

TradeWeb will continue to work closely with Thomson Financial on developing new and innovative solutions for non-traders.

Merrill Lynch acted as financial advisor and Fried, Frank, Harris, Shriver & Jacobson LLP acted as legal advisor to Thomson on the transaction. Cleary Gottlieb Steen & Hamilton LLP acted as legal advisor to the group of investing dealers.
