THOMSON FINANCIAL AND STREAMVPN PARTNER TO DELIVER ALPHA NETWORK ON THOMSON ONE

Leading Equity Research Filter Fully Integrated in Thomson ONE Platform,
Enabling Money Managers and Analysts to Tailor Flow of Research to Their Needs

London, July 5, 2005 --Thomson Financial, an operating unit of The Thomson Corporation (NYSE: TOC, TSX: TOC), and leading provider of information and technology solutions to the worldwide financial community, today announced a partnership with StreamVPN to deliver StreamVPN’s Alpha Network across the Thomson ONE solution. Alpha Network, a service employed by some of the world's largest buyside and sellside firms, helps fund managers identify and assess the trading ideas best suited to their particular investment criteria.

Alpha Network, first launched in Europe in 2003, filters broker supplied actionable ideas, much as stock screening tools find stocks meeting specified criteria. The buyside client sets the screening parameters, nominating specific sellside firms and individuals and creating other filters such as focus industries, market cap, geographic location and long or short. Brokers input their high conviction ideas meeting these criteria through a web-based private network which then tracks the performance of those ideas - providing a basis for allocating commissions based on value added.

"The integration of Alpha Network into Thomson ONE complements Thomson Financial’s breadth of premium research content and analysis, and underscores our commitment to provide our customers with a tailored solution specific to their needs," said Eric Frank, global managing director, Investment Management, Thomson Financial. "Through this partnership, our customers will be able to access one of the market’s most innovative tools for capturing alpha-generating ideas provided by the sellside"

"We are delighted to offer our existing and future clients the opportunity to access their Alpha Networks through Thomson ONE," said Simon Merchant, StreamVPN’s CEO. "Thomson ONE’s premium research content and analysis is the perfect context for portfolio managers to access the customized flow of high conviction ideas provided by the Alpha Network. Our Partnership with Thomson is an exciting step in the global roll-out of our Alpha Network services."

Thomson ONE is a new model for the information business. Its open framework is the most flexible in the industry, integrating Thomson Financial content and products, relevant third-party applications and proprietary content in solutions that are configured to the workflows of end users and the objectives of their businesses.
