                         PERSISTENCE SOFTWARE ANNOUNCES
                        SECOND QUARTER FINANCIAL RESULTS

         SAN MATEO, CALIF. -- JULY 24, 2003 -- Persistence(R) Software (NASDAQ:
PRSW), a leading provider of data services software for distributed data access
and management, today announced financial results for the second quarter ended
June 30, 2003.

         For the quarter, revenues were $2,876,000, compared with $2,523,000 for
the first quarter of 2003. The Company reported a net loss of $624,000, or
$(0.26) per share compared with a net loss of $1,008,000 or $(0.42) per share
for the first quarter of 2003. Revenues for the second quarter last year were
$5,730,000 with a net profit of $215,000 or $.10 per share. All per share
numbers have been adjusted to reflect a 1-for-10 reverse stock split that was
effected in the second quarter of 2003.

          Cash balances at June 30, 2003 were $ 6.2 million compared to $7.1
million as of March 31, 2003 and $7.3 million as of June 30, 2002.

            Christopher Keene, chief executive officer of Persistence Software,
Inc., commented, "We were pleased to see the license revenue component grow by
28 percent compared to the first quarter of 2003. At the same time, our loss
narrowed by 38 percent from the first quarter of this year as we continue to
conservatively manage expenses."

         Mr. Keene continued "Yesterday we announced that NetJets(R), the
fractional jet ownership leader and pioneer, has successfully deployed
Persistence's data services architecture, which integrates and continuously
synchronizes all information within the business so that critical applications
all have the same up-to-date information about customers, planes and crews. This
customer is indicative of the wide range of applications where Persistence's
Data Services products can improve the efficiency for sharing and distributing
critical data."

         The Company will discuss these results in a conference call scheduled
for 4:15 p.m. Eastern July 24, 2003. Interested parties can access the call by
