Second Quarter Press Release

             GENTIA SOFTWARE REPORTS RECORD SECOND QUARTER REVENUES
             ------------------------------------------------------

          Continues to Dominate Networked Business Intelligence Market
                  Success in Competing for Blue Chip Customers
                           New Strategic Partnerships

BOSTON, July 31, 1997 - Gentia Software plc (Nasdaq: GNTIY - formerly Planning
Sciences International plc) developer of the world's only networked business
intelligence environment for enterprise-wide deployment, today reported net
income of $544,000 or $0.05 per share, on record second quarter revenues of $8.1
million. In last year's second quarter the company's net income was $574,000 or
$0.05 per share, on revenues of $6.1 million.

Paul Rolph, chairman and chief executive officer, noted that Gentia's revenue in
this year's second quarter was 16% higher than in the preceding quarter and 33%
higher than in the comparable period of 1996.

"Our gains in the U.S. market have been particularly strong," Mr. Rolph said.
"After formal competitive assessment, in the second quarter, Gentia was selected
by major American corporations including J.P. Morgan and Company, Federal
Express, Sun Microsystems and Hewlett-Packard. In addition, we announced
partnerships with Sybase and Informix that we expect to contribute significantly
to our continued success."

Mr. Rolph said Gentia sees great opportunities to accelerate its momentum and
increase its market share by making a significantly greater investment in sales
and marketing in the second half of 1997.

"We intend to seize these opportunities, and we believe that doing so will
enhance our ability to continue rapid rates of growth in 1998 and beyond," he
said. "Gentia Software sees itself as being in a battle for market share. We
know we have the technology to win that battle, and we are going to be
relentless in our pursuit of success."

Mr. Rolph said Gentia is continuing to win more than 80 per cent of competitive
bid situations in which it is a candidate. He said the new "Networked Business
Intelligence" marketing campaign, initiated by worldwide marketing vice
president Scott Silk, is proving to be an important factor in revenue growth.

"We also changed our company name from Planning Sciences International plc to
Gentia Software plc at the end of the second quarter," Mr. Rolph said. "Though
the costs of this change had a moderately adverse impact on the quarter's net
income, the change is more than worth the cost. The new name reinforces both our
product brand and our position as the world leader in Networked Business
Intelligence."

In this year's second quarter the company had noteworthy competitive success not
only in the U.S. but also in Europe, where it has been selected recently by
accounts such as Swiss Reinsurance in the financial sector.

Approximately 42% of Gentia's first half 1997 revenues came from the U.S., while
27% came from the U.K. This compares with 39% from the U.S. and 40% from the
U.K. a year earlier. While U.S. sales have exceeded Gentia's targets, a recent
failure to meet objectives in the U.K. has led to extensive staffing and
structural changes there.

"The change we've made in our U.K. sales operations have been far-reaching," Mr.
Rolph said. "The problems that made those changes necessary have now been
addressed, and our actions have cleared the way to greatly improved performance.
I am confident of better results in the U.K. by year-end."

He said the company also plans to enter the Japanese market by the end of 1997.
