NEW YORK, NY - March 4, 2009 - Thomson Reuters (NYSE: TRI; TSX: TRI; LSE: TRIL; NASDAQ: TRIN) today announced that long-term incentive awards of performance restricted share units (PRSUs) and stock options were granted on March 3, 2009 to the following individuals:

Name	Title	PRSUs	Options
Thomas H. Glocer	Chief Executive Officer	77,070	366,960

James C. Smith	Chief Executive Officer, Professional division	39,780	189,400
Devin Wenig	Chief Executive Officer, Markets division	39,780	189,400

PRSUs will vest on March 1, 2012 upon completion of a three-year performance cycle (2009-2011) and will entitle holders to receive Thomson Reuters Corporation common shares if threshold performance goals are met. The final number of PRSUs that vest will vary from 0% to 200% of the initial number awarded, based 50% on Thomson Reuters adjusted EPS growth and 50% on its return on invested capital (ROIC) performance at the end of the three-year period. PRSUs will also accumulate additional units based on notional equivalents of dividends paid on Thomson Reuters Corporation common shares. The accumulated dividends, which are credited only on the shares actually earned, will be paid at the time that underlying shares are distributed.

Options will vest 25% per year over four years. The exercise price for the options granted is US$23.25 per share, which was the closing price of Thomson Reuters Corporation's common shares on the New York Stock Exchange on March 2, 2009. The options will expire 10 years from the grant date.

In addition, Mr. Daleo received 8,048 Thomson Reuters Corporation common shares today in connection with the vesting of PRSUs previously granted to him as long-term incentive awards for the three-year performance period that ended on December 31, 2008.
