MRO SOFTWARE REPORTS SECOND QUARTER RESULTS

Vertical Solutions Drive MAXIMO Results

BEDFORD, Mass., April 15, 2004 - MRO Software, Inc. (Nasdaq: MROI), the leading

the Company's second quarter ended March 31, 2004.

Total revenues for the second quarter were $44.6 million compared with $39.4
million for the second quarter last year, an increase of 13 percent. On a GAAP
basis, the Company reported net income for the second quarter of $1.4 million or
$0.05 per diluted share, compared with a net loss of $0.2 million or $0.01 per
share for the second quarter of fiscal 2003.

Pro forma net income (see Schedule A) for the second quarter was $2.0 million,
or $0.08 per diluted share compared with pro forma net income of $0.5 million,
or $0.02 per diluted share for same quarter last year. Pro forma results are
adjusted for the amortization of acquired technology and other intangibles and
the related tax effects.

For the second quarter, revenues from software license sales were $11.5 million,
compared with $7.7 million for the same quarter last year, an increase of 49
percent. Support and services revenues were $33.2 million for the second
quarter, compared with $31.7 million for the same quarter last year, an increase
of 5 percent.

During the second quarter, the Company sold 215 software licenses. Customers
across a range of industries and geographies purchased MRO Software products
during the quarter including: ABB Global, Aramark, Aventis Pharma, China
National Offshore Oil Company (CNOOC), Cornell University, Fort Worth Water
Department, Honda Manufacturing, National Park Service, Sarasota County
Utilities, Seagate, State of Michigan, Scottish and Southern Energy, Taylor
Woodrow Construction, Thames Water International Business Systems, The British
Library, U.S. Army, U.S. Department of Energy, U.S. Department of Defense, U.S.
Navy and the University of Western Australia.

The balance sheet as of March 31, 2004 contained $96.5 million in cash and
marketable securities and no long-term debt. For the second quarter, deferred
revenue increased to $32.1 million, and days sales outstanding (DSO) improved to
62 days.



"We continue to focus and execute on our two most important initiatives -
industry solutions and MAXIMO 6," said Chip Drapeau, president and CEO, MRO
Software. "With our industry-specific MAXIMO solutions we are able to
differentiate MAXIMO from the competition and drive deeper into our core
markets. At the same time, our investment in MAXIMO 6 will deliver the next
generation of functionality for our traditional customer base, and open the door
into new markets, impacting our performance in calendar 2005."

"I'm pleased with the financial strength of the Company," said Peter Rice,
executive vice president and CFO, MRO Software. "During the quarter we reduced
DSO and generated more than $6 million in cash to bolster our already strong
balance sheet. As a result, we are well positioned to fund our current and
future growth initiatives."

Rice continued, "For fiscal year 2004, the Company reaffirms its expectation for
earnings to grow into the range of $0.30-$0.40 per share on a GAAP basis or
$0.40-$0.50 per share on a pro forma basis. These expected earnings are based on
revenue growth of approximately 5 percent above fiscal 2003 results.
Specifically, for the third quarter of fiscal 2004, we expect revenues to be in
the range of $45 to $47 million, and we expect earnings to be in the range of
$0.08 to $0.10 per share on a GAAP basis, and between of $0.10 to $0.12 per
share on a pro forma basis."

Expected results on a pro forma basis are adjusted for the amortization of
acquired technology and other intangibles and the related tax effects.

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 the 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 comparision 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.
