          EPICOR RELEASES PRELIMINARY ESTIMATE OF FINANCIAL PERFORMANCE
                      FOR THE SECOND FISCAL QUARTER OF 1999

         IRVINE, Calif., July 7, 1999 -- Epicor Software Corporation (NASDAQ:
EPIC), today released preliminary financial performance estimates for the second
fiscal quarter ended June 30, 1999. For the quarter, the company expects to
report total revenue slightly below that of its first fiscal quarter with
earnings per share at or near breakeven.

         The company believes that its revenue and earnings growth were
adversely affected by several factors including continuing merger-related sales
performance issues and a general industry-wide slowdown in demand for ERP
software. Second quarter results were also impacted by the reclassification of
the company's Impresa operation (from an asset held for sale) to an on-going
entity.

         "We expect revenue levels in the third and fourth quarters of the
current fiscal year to be similar to those of the second quarter, principally
due to an industry-wide slowdown," said George Klaus, chairman, president and
CEO of Epicor. "We do not believe this reflects the long-term growth prospects
of either the enterprise software market or Epicor. Notwithstanding these
industry trends, we remain confident that the merger of Platinum and DataWorks
brought together the resources necessary for Epicor to emerge as the leading
supplier of business performance solutions. We are firmly committed to operating
and positioning our business for long-term success."

         The company plans to report final second fiscal quarter financial
results on July 29, 1999.
