              BMC SOFTWARE ANNOUNCES PRELIMINARY FINANCIAL RESULTS
                          FOR FIRST QUARTER FISCAL 2005


HOUSTON -- (July 7, 2004) -- BMC Software, Inc. (NYSE: BMC) today released
preliminary financial results for the first quarter of fiscal 2005. BMC Software
preliminarily estimates total revenues for the first quarter ended June 30, 2004
to be in the range of $318 million to $328 million, which is below the estimated
revenue range of $345 million to $355 million that the Company provided in
April. Earnings per share excluding special items for the first quarter of
fiscal 2005 are preliminarily estimated to be in the range of $0.11 to $0.14 per
diluted common share, which compares to the earnings per share estimated range
of $0.12 to $0.16 provided by the Company in April. First quarter of fiscal 2005
earnings per share on a GAAP basis are preliminarily estimated to be in the
range of $0.19 to $0.22 per diluted common share. The difference between the
earnings per share excluding special items and the GAAP earnings per share is
that the earnings per share excluding special items does not include $0.05 per
diluted common share related to amortization of acquired technology and
intangibles and a benefit of $0.13 per diluted common share related to a recent
settlement of a United States tax audit. BMC Software will report final first
quarter results on July 27th.

         At the end of the quarter, the Company experienced delays in customer
purchasing decisions among larger accounts, primarily in the United States. The
Company completed 9 license transactions worldwide in excess of $1 million in
the first quarter of fiscal 2005, compared to 16 license transactions in excess
of $1 million in the same quarter of last year.

         License bookings are estimated to be down 20 to 26 percent compared to
the first quarter of last year. License bookings measure the value of new
license contracts signed


                                       5


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.

          A conference call to discuss preliminary first quarter results is
scheduled for today at 4:00 p.m. central time. Those interested in participating

The preliminary financial estimates and statements concerning BMC Software's
future prospects contained in this press release are "forward-looking
statements" under the Private Securities Litigation Reform Act of 1995. The
preliminary estimates of revenues, earnings per share and license bookings
contained in this press release are subject to change. BMC Software will report
final financial results for the June 2004 quarter on July 27th after it has had
additional time for the collection and compilation of additional financial data.
These final financial results for the June 2004 quarter could be materially
different from the estimates in this press release. Numerous important factors
affect BMC Software's operating results and could cause BMC Software's actual
results to differ materially from forecasts and estimates or from 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 continued 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
continue to 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; and 8) the additional
risks and important factors described in BMC Software's quarterly reports on


                                       7


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.
