Thomson Reuters to Acquire Sabrix

Tax & Accounting business adds to ONESOURCE corporate solutions for global transaction tax

NEW YORK, November 16 - Thomson Reuters (NYSE: TRI; TSX: TRI), the world's leading source of
intelligent information for businesses and professionals, today announced
that its Tax & Accounting business has signed a definitive agreement to
acquire Sabrix, Inc, a leading global provider of transaction tax management
software applications and related services. Headquartered in San Ramon, CA,
with additional operations in Oregon and London, all 160 Sabrix employees
will transfer into Tax & Accounting upon the close of the transaction, which
is expected in December 2009.

"This acquisition fulfills our vision of delivering a comprehensive
global solution for corporations in the area of transaction tax, especially
companies with a multinational presence" said Roy M. Martin, Jr., President
and CEO of Tax & Accounting. "Sabrix offerings, which cover rates and rules
for 170 countries, will be integrated with our existing local transaction tax
software and services to form a total solution for corporate customers in the
U.S., the U.K. and Europe."

Transaction tax, also known around the world as indirect tax, VAT, GST or
sales & use tax, trails only corporate and personal income taxes in its
pervasiveness among country governments.

"Sabrix applications can process an unlimited number of transactions,
control audit exposure, and reduce the total cost of sales tax, use tax, and
VAT compliance," said Brian Peccarelli, president of Corporate Software &
Services for Tax & Accounting. "Additionally, the Sabrix Managed Tax
Service(TM) offers finance departments of small-to-medium sized businesses an
outsourced transaction tax compliance service."

"We have collaborated with Thomson Reuters for years," said Steve Adams,
president and CEO of Sabrix. "We look forward to working alongside the
well-known and respected brands of the Tax & Accounting business, including
ONESOURCE and Checkpoint, so that Sabrix clients can continue to achieve
compliance with confidence in the most efficient and effective manner
possible."

Terms of the transaction were not disclosed.
