In connection with the offering, Thomson has applied to list its common shares on the New York Stock Exchange. The offering includes 14,615,385 newly issued common shares from Thomson and 23,384,615 common shares currently held by Woodbridge. 5,700,000 additional common shares currently held by Woodbridge are subject to an over-allotment option at the discretion of the underwriters of the offering. Proceeds from the offering are expected to range from $1.3 billion to $1.5 billion (depending upon the exercise of the over-allotment option), of which approximately $500 million will come from the issue of new shares by Thomson and the balance from the sale of shares currently held by Woodbridge. Thomson will not receive any proceeds from the sale of shares by Woodbridge. Proceeds received by Thomson will be used for general corporate purposes including the repayment of existing indebtedness. Thomson expects this offering to be completed by the end of the second quarter of 2002. Merrill Lynch & Co. and Morgan Stanley will act as joint bookrunning managing underwriters for the proposed offering. RBC Capital Markets, Bear, Stearns & Co. Inc., Credit Suisse First Boston, Goldman, Sachs & Co., TD Securities and UBS Warburg will act as co-managers. -more- 4
