                    IRI COMMENTS ON PROCTER & GAMBLE DECISION

CHICAGO - DECEMBER 13, 2002 - Information Resources, Inc. (NASDAQ: IRIC), a
leading provider of consumer behavior insights to the consumer packaged goods
(CPG) industry, was informed today that Procter & Gamble will not be renewing
its U.S. market measurement business with the Company. The current contract
expires in July 2003.

"Obviously, we are surprised and disappointed with Procter & Gamble's decision,"
said Joe Durrett, IRI Chairman and CEO. "P&G is one of our largest clients and
their loss will certainly be felt. Although we will no longer be P&G's primary
U.S. market measurement supplier, we have had a strong and collaborative
partnership with P&G in many other areas and we hope and expect that this
relationship will continue. The fact that the contract runs through the middle
of next year gives us some time to fully determine and take the necessary
actions required to offset this loss of business. In the meantime, we remain
committed to serving and delivering value and innovation to our customers, as
well as continuing to maintain a strong balance sheet," said Durrett.
