| NEON(R) Systems, Inc. (Nasdaq: NESY) announced today record results for both the third quarter of its fiscal year 2000 and for the nine months ended
 December 31, 1999.  The record third quarter results were driven by a 59%
 increase in license revenue over the comparable fiscal 1999 quarter.  Total
 revenues for the current nine-month period have increased 52% over the
 comparable fiscal 1999 nine-month period.
 Total revenues for the third quarter of fiscal 2000 increased 52% to a
 record $8.9 million, compared with revenues of $5.8 million in the third
 quarter of fiscal 1999.  NEON Systems also achieved record-setting
 profitability in the quarter with net income and diluted earnings per share of
 $1.5 million and $0.14, a 50% increase, compared to net income and diluted
 earnings per share of $968,000 and $0.14 for the same period in fiscal 1999.
 The diluted earnings per share calculation for the quarter ended
 December 31, 1998 does not include the 3,041,000 new common shares issued by
 NEON Systems in its March 1999 IPO.
 Total revenues for the nine months ended December 31, 1999 were
 $21.1 million, a $7.3 million, or 52% increase over revenues of $13.8 million
 for the first nine months of the prior year.  For the nine months ended
 December 31, 1999, net income and diluted earnings per share were $3.4 million
 and $0.32, respectively, a 146% increase, compared to net income and diluted
 earnings per share of $1.4 million and $0.20, respectively, for the nine
 months ended December 31, 1998.  The diluted earnings per share calculation
 for the nine months ended December 31, 1998 does not include the new shares
 issued by NEON Systems in its March 1999 IPO.
 "The end of the calendar year quarter continues to be a strong growth
 quarter for our business," said President and CEO of NEON Systems, Joe Backer.
 "We are particularly pleased with the strong license revenue growth
 performance due to continuing customer and prospect enthusiasm for high
 performance, scaleable, and secure software solutions for their e-business
 initiatives.  We are optimistic as we enter a new market period in which our
 customers will not be distracted by Y2K issues and are free to focus on new
 business applications and e-commerce initiatives which will benefit from our
 unique solutions."
