                       OTHER MANAGEMENT CHANGES ANNOUNCED

PARIS, FRANCE, AND MOUNTAIN VIEW, CALIF. - Aug. 1, 2000 - ILOG (NASDAQ and
EURO.NM: ILOG) today announced the appointment of Jean-Francois Abramatic,
chairman of the World Wide Web Consortium (W3C), as senior vice president of
research and development, reporting to president and chief executive officer,
Pierre Haren. Abramatic has been a member of ILOG's board of directors since
1994 and is resigning from this position upon joining the ILOG management team.

Other management changes announced today are the appointment of Christian
Deutsch to the newly created position of vice president of operations, the
departures of Stuart Bagshaw, chief operating officer, and Manuel Montalban,
vice president and general manager of the Telecommunications Business Division,
and the appointment of Eric Brisson as Montalban's successor.

Abramatic was responsible for establishing the W3C European host at INRIA (the
French national institute for computer science) in partnership with the
Massachusetts Institute of Technology (MIT) in 1995, becoming W3C chairman the
following year. During his tenure, W3C membership grew to more than 400
organizations, having become an international consortium with a presence in
Africa, Asia, Australia, Europe and North America. To date, W3C has developed
more than 20 recommendations for technologies critical to Web architecture,
including HTML, CSS and XML. Abramatic will remain as W3C chairman to give W3C
the time to evolve its management organization. Abramatic is former director of
development and industrial relations for INRIA, as well as former associate
director of the MIT Laboratory for Computer Science. He received an engineering
degree from Ecole des Mines, Nancy, France, in 1971 and a Ph.D. from the
University of Paris VI in 1980. "I have known Pierre Haren since 1984 and have
watched ILOG grow," said Abramatic. "I also served on ILOG's board during the
last six years and was impressed with the company's business strategy. If I were
to choose the most logical place for me in the industry, this was it. ILOG's
advanced technologies are increasingly being accepted as key components of the
Internet infrastructure, and I'm looking forward to helping lead the on-going
effort to bring these powerful technologies to e-Business, since they can play
an important role enabling customer self-service and providing a richer web
experience for users." Patrick Albert, ILOG's co-founder and chief technology
officer and executive vice president of core research and development, continues
as ILOG's chief technology officer, focusing on the company's longer-term
technical strategies and directions.
