Lehman Brothers Joins TradeWeb’s Euro Interest Rate Swaps Platform

--Thomson TradeWeb IRS now offers forward dates and off-benchmark swaps - the first available electronically on a multi-dealer system -- 

LONDON, 13 June 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 Lehman Brothers will be a liquidity provider on TradeWeb's fast-growing electronic Euro Interest Rate Swaps platform. Lehman Brothers, the global investment bank with a prominent fixed income franchise, is an active market maker in interest rate derivatives.

The firm's endorsement of electronic Interest Rate Swaps trading in the dealer-to-client space underscores the growing market demand for TradeWeb's proven technology. Lehman Brothers joins the IRS platform's founding members JPMorgan, Barclays Capital, Morgan Stanley, Dresdner Kleinwort Wasserstein, HSBC and ABN AMRO, and more dealers are preparing to join the system.

TradeWeb also announced that its IRS platform has been significantly expanded to offer forward starting interest rate swaps and off-benchmark swaps. Using TradeWeb Swaps 'request for quote' (RFQ) model, institutional investors can now tailor their transaction beyond plain vanilla swaps to incorporate specific termination dates and other parameters. TradeWeb is the only electronic multi-dealer system to offer this new functionality.

The extended trading platform is the only one of its kind to be fully integrated with ISDA confirmation functionality, providing further efficiencies to the buy- and sell-side, including significant reductions in operational risk, and improvements in operational efficiency.

Lee Olesky, President of Thomson TradeWeb, commented: "Electronic Swaps trading has been rapidly accepted across the buy- and sell-side markets, and we are very pleased to count Lehman Brothers among our leading liquidity providers. Our initial group of buy-side customers has more than doubled since we launched the interest rate swaps platform in February, and we expect to have some 100 customers across Europe by the end of the year. Additionally, we remain on track for adding other currencies and enhancing functionality further in the coming months."

Thomas Siegmund, Head of Interest Rates Trading at Lehman Brothers said: "Electronic connectivity with our clients on a competitive IRS trading platform augments our growing Fixed Income franchise to a global clientele. A multi-dealer platform covering the complete trade cycle is a natural choice for Lehman Brothers."

Guido Behrendt, Head of Asset Swaps at Deutsche Postbank AG, commented: "TradeWeb is establishing itself as an important tool for us when trading interest rate swaps. We are very pleased with the system -- it is fast, flexible and easy to use."
