million in the same quarter last year, a decrease of 15 percent. Support and
services revenue was $33.3 million, compared with $32.3 million in the same

"We were able to deliver solid results for the quarter. Our focus on vertical

nuclear, transportation and federal sectors during the quarter," said Chip
Drapeau, president and CEO, MRO Software. "With our healthy balance sheet we are
able to continue investing in solutions and activities that will help to grow
the Company."

"The Company's earnings, operating margins and cash balances continued to
improve this quarter," said Peter Rice, CFO, MRO Software. "For the fourth
quarter of fiscal 2004, we expect revenues to be in the range of $47 to $49
million, and we expect earnings to be in the range of $0.12 to $0.16 per share
on a GAAP basis, and between $0.14 to $0.18 per share on a pro forma basis.
Based on these expectations, the Company reaffirms its guidance for fiscal year
2004 total revenue growth of approximately 5 percent and pro forma earnings
growth of approximately 50 percent above fiscal 2003 results. Looking ahead for
fiscal year 2005, we expect total revenue growth of five percent and pro forma
earnings growth in the range of 10 to 15 percent for the full fiscal year."

Note:

     In this press release, the Company announced its earnings per share (EPS)
     on a GAAP and pro forma basis. Pro forma net income for fiscal year 2004
     and 2003 is adjusted to exclude the amortization of acquired technology and
     other intangibles and their related tax effects.

     Management believes that such pro forma EPS is useful to investors, first
     because it is important for investors to receive information in a form that
     is consistent with the Company's past practice, and second because the
     Company's amortization of acquired technology and other intangibles is
     substantially fixed, and is relatively large in comparison with the
     absolute value of the Company's operating income. The Company believes that
     by focusing on the impact of expenses that are to a greater extent subject
     to control by the Company's management, pro forma EPS provides investors
     with a more direct perspective on the performance of the Company and its
     management.
