STAMFORD, Conn. -- (BUSINESS WIRE) -- May 6, 2002 -- Information Holdings Inc.
(NYSE: IHI - news) announced that it has entered into an agreement to acquire
essentially all of the assets of Aurigin Systems, Inc. (Aurigin) for cash
consideration of approximately $12.4 million and the assumption of certain
liabilities.

The company expects to complete the transaction within two weeks.

Aurigin provides intellectual property (IP) management systems, used primarily
by corporations to search, analyze, annotate and group patent information, as
well as proprietary corporate data. Aurigin will be integrated with the
MicroPatent unit of IHI's Intellectual Property Group. The Company expects that
Aurigin, which has been operating under Chapter 11 bankruptcy protection, will
become profitable following a 3-6 month transition period.

Commenting on the transaction, Mason Slaine, President & CEO said, "Aurigin
represents an important strategic acquisition for IHI. With previous equity
investments approximating $65 million, Aurigin has been able to develop highly
advanced IP analytical tools. When combined with MicroPatent's comprehensive IP
databases, the patented Aurigin technologies will enable us to offer
unparalleled value-added IP management solutions."
