Thomson Reuters to Acquire Complinet

Global financial compliance services leader to expand Thomson Reuters compliance offerings to financial and legal markets

NEW YORK, June 3, 2010 - Thomson Reuters, the world's leading source of intelligent information
for businesses and professionals, today announced that it will acquire
Complinet, a leading provider of global compliance information solutions for
financial services institutions and their advisers. Terms of the deal,
expected to close in the second quarter, were not disclosed.

Regulation is a major driving force shaping financial services globally,
and every indication is that this trend will only increase. Complinet, which
is based in London and has more than 200 employees, brings a leading market
position, powerhouse brand, strong management team, and assets across the
entire global regulatory compliance workflow to Thomson Reuters.

"Across the globe, our customers are increasingly focused on information
and software solutions that address their needs in governance, risk and
compliance. The acquisition of Complinet, when coupled with the deep
resources of our existing legal and financial services businesses, will take
Thomson Reuters to a leadership position in this fast-growing market," said
Thomas H. Glocer, chief executive officer, Thomson Reuters.

"I am pleased that Complinet with its talented team will be joining our
company."

Complinet's services are seen as a tremendous complement to Thomson
Reuters existing professional information and software assets, and to its
base of customers in global legal and financial markets. The deal also will
further Thomson Reuters vision to provide end-to-end financial service
compliance solutions, while building upon Complinet's already-strong market
position. Together, Thomson Reuters and Complinet will help firms make
intelligent commercial decisions based on a deeper and more connected
understanding of all regulatory risks.

Chris Pilling, Complinet CEO and founder, said the deal with Thomson
Reuters is the important next step in Complinet's natural evolution. "The
acquisition by Thomson Reuters will allow Complinet to fully realize its
vision, backed by the reach and resources of Thomson Reuters," he said.
"Current customers will only see improvements to the unique services and
quality they have come to expect from Complinet. Moving forward, we will see
the true potential of this business when aligned with the scale and global
footprint of Thomson Reuters."

Pilling will continue to lead Complinet and the business will continue to
serve its clients as before. Pilling will report to Peter Warwick, chief
executive officer of Thomson Reuters, Legal, and will work closely with
businesses pan-Thomson Reuters to fully leverage current global regulatory
compliance assets within both the Markets and Professional divisions.
