                         PERSISTENCE SOFTWARE ANNOUNCES
                         FIRST QUARTER FINANCIAL RESULTS

         SAN MATEO, CALIF. -- APRIL 24, 2003 -- Persistence(R) Software (NASDAQ:
PRSW), a provider of data services software for distributed data access and
management, today announced financial results for the first quarter ended March
31, 2003.

         For the quarter, revenues were $2,523,000, compared with $2,161,000 for
the first quarter of 2002. The Company reported a net loss of $1,008,000, or
$(0.04) per share, compared with a net loss of $3,309,000, or $(0.16) per share
for the same period last year. The Company reported a 35 percent decrease in
operating expenses, compared to the first quarter of last year. Cash balances at
March 31, 2003 were $7,101,000 compared to $7,189,000 for the same period last
year.
         Revenues for the prior quarter, ended December 31, 2002, were
$2,551,000 with a net loss of $1,897,000 or $(0.09) per share.

         During the quarter, the Company closed several new EdgeXtend clients,
including a major content management company and an international real-time
project management firm.

         Christopher Keene, chief executive officer of Persistence Software,
Inc., commented, " Although economic conditions remain challenging, we saw clear
validation in Q1 that increasing the number of customer pilots is the key to
growing revenue. We performed more pilots in the last three months than we did
in all of 2002. Even better, two of those pilots turn into revenue during the
quarter."

         Mr. Keene continued, "During the first quarter, we tightened our
strategic focus to address critical business problems in the financial and
transportation markets. In the financial market, we position EdgeXtend Data
Services as a way to meet the regulatory requirements of the Patriot Act for
better aggregation of counterparty reference data. In the transportation market,
we position EdgeXtend as a way to improve operating efficiency with continuously
up-to-date distribution of scheduling data."

         Mr. Keene concluded, "Last year we announced a sale of EdgeXtend for
IBM Websphere to Fiducia, the IT provider for hundreds of German banks.
Fiducia's application is now going into deployment and they are beginning to
realize significant cost and performance benefits delivered by EdgeXtend.
Earlier this week, we issued a press release in which both the Chief Software
Architect of Fiducia and the IBM Websphere Vice President spoke publicly for the
first time about their reasons for choosing EdgeXtend. We believe the success of
the Fiducia branch banking renewal project marks an important validation of the
strategy we have pursued since last year of partnering with market leaders such
as IBM."

         "Our disciplines in spending resulted in a 35 percent reduction in
operating expenses compared to the first quarter of 2002," commented Christine
Russell, Persistence's chief financial officer. "We ended the quarter with a

                                      -1-


cash position of more than $7 million on hand, and receivables increased nearly
60 percent while deferred revenue stayed relatively flat compared to the prior
quarter. Our gross margin at 81 percent for the quarter exceeded the 79 percent
we posted for the full year 2002, which is a positive. We will continue to
carefully manage our cash and our expenses as we navigate these challenging
economic conditions."

         THE COMPANY WILL DISCUSS THESE RESULTS IN A CONFERENCE CALL SCHEDULED
FOR 4:15 P.M. EASTERN APRIL 24, 2003. INTERESTED PARTIES CAN ACCESS THE CALL BY
DIALING (800) 289-0436 OR BY ACCESSING THE WEB CAST AT WWW.PERSISTENCE.COM. A
