              BMC SOFTWARE REPORTS FIRST QUARTER FINANCIAL RESULTS

     HOUSTON -- (July 27, 2004) -- BMC Software, Inc. [NYSE: BMC] today
announced financial results for its fiscal 2005 first quarter ended June 30,
2004.

      BMC Software's net earnings excluding special items for the first quarter
of fiscal 2005 were $32.1 million, or $0.14 per diluted common share, which
compares to $0.03 a year ago and the Company's revised guidance range of $0.11
to $0.14 provided earlier this month. The fiscal 2005 first quarter net earnings
on a GAAP basis were $51.8 million, or $0.23 per share, which compares to a net
loss of $6.1 million, or a loss of $0.03 per share, in the first quarter of
fiscal 2004. Included in the financial tables is a reconciliation of results
excluding special items and GAAP results.

      Total revenues in the first quarter of fiscal 2005 were $326.0 million, an
increase of 5 percent compared to the first quarter of fiscal 2004, and was
within the Company's revised guidance of $318.0 million to $328.0 million
provided earlier this month. Operating expenses, excluding special items, were
$299.0 million, compared to $321.5 million in the same quarter of fiscal 2004.

      "The first quarter presented a challenging revenue environment for our
industry and for BMC. While disappointed with our revenue performance, which was
in part due to weakness in the United States, I was pleased with our expense
controls and improved operating margins in the quarter," said Bob Beauchamp,
president and CEO, BMC Software.

      BMC Software maintained its strong financial position with cash flow from
operations in the quarter of $90.1 million. The cash and marketable securities
balance was $1.2 billion, and the total deferred revenue balance was $1.39
billion.

     BMC Software continued its stock repurchase program by spending $20.0
million to repurchase approximately 1.2 million shares during the first fiscal
quarter. Approximately $287 million remains in this program.

     License bookings in the first quarter of fiscal 2005 were $83.6 million, a
decrease of 20 percent compared to the first quarter of fiscal 2004. The
following table illustrates license bookings:

*License bookings measure the value of new license contracts signed during the
quarter, including both the amount that goes to the income statement and the
amount that goes to the deferred license revenue account on the balance sheet.
License bookings can be calculated by adding license revenues to the net change
in the deferred license revenue balance.

     SECOND QUARTER AND FISCAL 2005 GUIDANCE

     The Company expects second quarter revenues to be in the $340 to $355
million range and expects second quarter earnings per share excluding special
items to be in the $0.12 to $0.16 range. These expectations include an estimated
$10 million in revenues and a negative earnings per share impact of one cent
related to the recent acquisition of Marimba. Second quarter estimates do not
include an estimated $0.05 per share of amortization of acquired technology and
intangibles, exclusive of the Marimba acquisition.

     The Company expects fiscal 2005 revenues to be in the $1.46 to $1.49
billion range and expects fiscal 2005 earnings per share excluding special items
to be in the $0.64 to $0.74 range. These expectations include an estimated $30
million in revenues and a negative earnings per share impact of two cents
related to the recent acquisition of Marimba. Fiscal 2005 estimates do not
include an estimated $0.20 per share of amortization of acquired technology and
intangibles, exclusive of the Marimba acquisition.

     NON-GAAP FINANCIAL MEASURES

     This press release includes financial measures for net earnings, earnings
per share (EPS) and operating expenses that exclude certain charges and,
therefore, have not been calculated in accordance with U.S. generally accepted
accounting principles (GAAP). A detailed reconciliation between the GAAP results
and results excluding special items (non-GAAP) is included with the financial
tables accompanying this press release. BMC Software has provided these non-GAAP
measures in its press releases reporting historical financial results because
the Company believes these measures provide a consistent basis for comparison
between quarters, as they are not influenced by certain non-cash or
non-recurring expenses and are therefore useful to investors in helping them
understand the financial condition of BMC Software by focusing on the
performance of its core operations. Management uses these non-GAAP financial
measures internally to evaluate the Company's performance and as a key variable
in determining management compensation. These non-GAAP measures should not be
considered an alternative to GAAP, and these non-GAAP measures may not be
comparable to information provided by other companies.

     This news release contains both historical information and forward-looking
information. Statements of plans, objectives, strategies and expectations for
future operations and results, identified by words such as "believe,"
"anticipate," "expect," "estimate" and "guidance" are forward-looking
statements. Numerous important factors affect BMC Software's operating results
and could cause BMC Software's actual results to differ materially from the
results indicated by this press release or by any other forward-looking
statements made by, or on behalf of, BMC Software, and there can be no assurance
that future results will meet expectations, estimates or projections. These
factors include, but are not limited to, the following: 1) BMC Software's
revenues and earnings are subject to a number of factors, including the
significant percentage of quarterly sales typically closed at the end of each
quarter, that make estimation of operating results prior to the end of a quarter
extremely uncertain; 2) BMC Software's operating costs and expenses are
relatively fixed over the short term; 3) increased competition and pricing
pressures could adversely affect BMC Software's earnings; 4) growth in BMC
Software's mainframe revenues is dependent on demand for significant additional
mainframe MIPS capacity; 5) BMC Software's maintenance revenue could decline if
maintenance renewal rates decline or if license revenues do not grow; 6) new
software products and product strategies may not be timely introduced or
successfully adopted; 7) BMC Software's quarterly cash flow from operations is
and has been volatile and is dependent upon a number of factors described in BMC
Software's filings with the SEC; 8) BMC Software's effective tax rate is subject
to quarterly fluctuation and any change in such tax rate could affect the
Company's earnings; and 9) the additional risks and important factors described
in BMC Software's quarterly reports on Form 10-Q and in its Annual Report to
Stockholders on Form 10-K for the fiscal year ended March 31, 2004 and other
filings with the SEC. BMC Software undertakes no obligation to update
information contained in this release.
