Supplemental schedule of noncash financing and investing activities (in
thousands):

In October 1999, the Company acquired all of the stock of OPUS 2 Revenue
Technologies, Inc. ("OPUS"), pursuant to the terms of a stock purchase
agreement. The purchase price of $4.8 million for OPUS consists of an up-front
payment of both cash of $3.8 million and MICROS stock valued at $1.0 million.
The Company issued 24,510 shares (in whole shares) of restricted common stock to
the former owners (See note 5 of Notes to Consolidated Financial Statements).
Additionally, the selling shareholders may be entitled to earn certain earn-out
payments. The payment, if any, and the amount shall be determined by an earn-out
formula, based on OPUS' future financial performance.

In December 1999, the Company acquired all of the stock of Stanley Hayman and
Company, Inc ("Hayman") and MICROS of South Florida, Inc ("MSF"). Hayman and MSF
are affiliate companies with substantially similar shareholders. The purchase

December 1999 and paid in January 2000 (See note 5 of Notes to Consolidated
Financial Statements). Additionally, the selling shareholders may be entitled to
earn certain earn-out payments. The payment, if any, and the amount shall be
determined by an earn-out formula, based on Hayman's and MSF's collective future
financial performance.

2.      New accounting standards

        In December 1999, the Securities and Exchange Commission issued Staff
        Accounting Bulletin (SAB) No. 101, "Revenue Recognition in Financial
        Statements". This statement will not have an impact on the Company's
        consolidated financial position, results of operations or cash flows.

3.      Legal proceedings

        MICROS is and has been involved in legal proceedings arising in the
        normal course of business. The Company is of the opinion, based upon
        presently available information and the advice of counsel concerning
        pertinent legal matters, that any resulting liability should not have a
        material adverse effect on the Company's results of operations or
        financial position.

        On March 25, 1997, Budgetel Inns, Inc. ("Budgetel") filed suit against
        MICROS in the United States Federal District Court in the Eastern
        District of Wisconsin. Budgetel alleges, among other things, that MICROS
        breached a March 1993 software support agreement by failing to provide
        full support to this software package licensed to Budgetel in 1993.
        MICROS filed its answer to the complaint in September of 1999. MICROS
        also filed a counterclaim against Budgetel, alleging breach of contract
        and defamation. The litigation is currently in the discovery phase.
        While the ultimate outcome of litigation is uncertain, and while
        litigation is inherently difficult to predict, the Company is of the
        opinion, based upon presently available information and the advice of
        counsel concerning pertinent legal matters, that resulting liability, if
        any, should not have a material adverse effect on the Company's results
        of operations or financial position.


4.      Net income per share

        Basic net income per common share is computed by dividing net income by
        the weighted-average number of shares outstanding. Diluted net income
        per share includes the dilutive effect of stock options.

5.      Acquisitions

        During the quarter the Company acquired five companies. The combined
        purchase price was $11.8 million, consisting of cash, MICROS stock, and
        debt. The total goodwill value as of December 31, 1999, was $11.5
        million.

        In October 1999, the Company acquired all of the stock of OPUS 2 Revenue
        Technologies, Inc. ("OPUS"), pursuant to the terms of a stock purchase
        agreement. Based in Portsmouth, New Hampshire, OPUS engages in the
        development, marketing and sale of yield and revenue management software
        systems designed for the hospitality industry. The purchase price of
        $4.8 million for OPUS consists of an up-front payment of both cash and
        MICROS stock. An additional payment of $.5 million was paid in January
        2000 for the purchase of Opus. Goodwill related to this acquisition was
        $5.8 million at December 31, 1999, and is being amortized over seven
        years. Additionally, the former shareholders have the right to earn: (i)
        three earn-out payments based on OPUS revenues, for the three periods

Item 2.  Management's Discussion and Analysis of Financial Condition and Results
         of Operations

Results of Operations - Second Quarter and Six Month Comparisons

        The Company recorded diluted net income of $0.48 per common share in the
second quarter of fiscal 2000, compared with diluted net income of $0.37 per
share in the second quarter of fiscal 1999. Net income for the six months ended
December 31, 1999, on a diluted basis, was $0.78 per share compared with $0.57
per common share for the first six months of fiscal 1999. For the quarter and
year-to-date, the increased net income was primarily due to higher sales volumes
generating a higher gross margin in absolute dollars and lower operating
expenses as a percentage of sales.

        Revenue of $102.7 million for the second quarter of fiscal 2000
increased $22.2 million, or 27.5%, compared to the same period last year. For
the first six months of fiscal 2000, revenue increased $42.9 million to $190.2
million, or 29.2%, over the same period in fiscal 1999. A comparison of the
sales mix for fiscal years 2000 and 1999 is as follows:

        For the quarter, both hardware and software sales continued to increase
in absolute dollars, but declined as a percentage of sales primarily due to the
continued growth of the Company's service business. Service sales increased in
absolute dollars and as a percentage of total sales for the second quarter in
comparison to the prior year primarily due to increased installation revenue. On
a year-to-date basis, hardware sales increased as a percentage of total sales
while software sales decreased. Hardware sales increased primarily due to
increased sales of the Company's own PCWS ("PC Workstation"). Service sales
increased in absolute dollars and as a percentage of total sales on a
year-to-date basis primarily due to increased installation and support revenues.

        Combined hardware and software revenues for the second quarter of fiscal
2000 increased $12.7 million, or 24.9%, while service revenues increased $9.4
million, or 32.0%, over the same period a year earlier. On a year-to-date basis,
hardware and software sales increased $24.6 million, or 26.6%, while service
revenues increased $18.3 million, or 33.5%, over the same period a year earlier.

        Cost of sales, as a percentage of revenue, increased to 51.8% for the
second quarter of fiscal 2000 from 50.7% for the second quarter of fiscal 1999.
For the first six months of fiscal 2000 and 1999, cost of sales, as a percentage
of revenue, was 52.3% and 50.5% respectively. Cost of sales for hardware and
software products, as a percentage of related revenue, was 54.0% in the second
quarter of fiscal 2000 compared to 52.2% for the same quarter a

year earlier and 54.5% compared to 51.1% for the first six months of fiscal 2000
and 1999, respectively. For the quarter, this increase was the result of
increased sales of lower margin third party software. The year to date increase
is primarily due to the increase of hardware sales as a percentage of total
hardware and software sales.

        Service costs, as a percentage of service revenue, increased to 48.2% in
the second quarter of fiscal 2000 compared to 47.9% in the same quarter in
fiscal 1999. Service costs, as a percentage of service revenue, decreased to
48.6% in the first six months of fiscal 2000 compared to 49.4% for the same
period in fiscal 1999. The second quarter increase in comparison to the prior
year was due to additional expenses incurred to resolve potential Year 2000
issues. The year-to-date decrease in comparison to the prior year was due to
continued expansion of the Company's customer base and the ability of the
Company to increase service revenues at a rate in excess of service costs.

        Selling, general and administrative expenses increased $5.0 million, or
22.5%, in the second quarter of fiscal 2000 compared to the same period last
year. As a percentage of revenue, selling, general and administrative expenses
decreased to 26.6% in the second quarter of fiscal 2000 compared to 27.7% in the
second quarter of fiscal 1999. For the first six months of fiscal 2000, selling,
general and administrative expenses, as a percentage of revenue, were 27.4%
compared to 28.6% for the same period a year earlier. For both the quarter and
year-to-date, these decreases are due to sales growth at a rate in excess of
these expenses.

        Research and development expenses (exclusive of capitalized software
development costs), which consist primarily of internal and sub-contracted labor
costs, increased $0.8 million, or 22.4%, in the second quarter of fiscal 2000
compared to the same period a year earlier. Actual research and development
expenditures, including capitalized software development costs of $1.7 million
in the second quarter of fiscal 2000 and $2.1 million in the second quarter of
fiscal 1999, increased $0.4 million, or 7.1%, compared to the same period a year
earlier. This increase in absolute dollars for the three-month period is
primarily due to increased expenditures for the Company's restaurant business.
For the first six months of fiscal 2000, research and development expenses
(exclusive of capitalized software development costs), which consist primarily
of internal and sub-contracted labor costs, increased $0.9 million, or 12.0%,
compared to the same period a year earlier. Actual research and development
expenditures for the first six months of fiscal 2000, including capitalized
software development costs of $3.2 million, decreased $.5 million, or 3.9%,
compared to the same period a year earlier. The decrease in absolute dollars for
the six-month period is primarily due to decreased expenditures in the Company's
hotel business during the second quarter of fiscal 2000.

        Office closure costs relate to follow-on costs incurred in the first
quarter of fiscal 1999 associated with the Company's fourth quarter of fiscal
1998 permanent closure of its facility in Munich, Germany. These costs relate to
the relocation of former Munich employees to their new places of employment
within the Company.

        Income from operations for the second quarter of fiscal 2000 was $14.7
million, or 14.4% of revenue, compared to income of $11.4 million, or 14.2% of
revenue, in the same period a year earlier. For the first six months of fiscal
2000, income from operations was $24.8 million compared to income of $18.3
million a year earlier. For both the second quarter and first six months of
fiscal 1999, the Company's higher dollar income from operations is primarily due
to higher sales volumes generating a higher gross margin in absolute dollars.

        Interest expense decreased $0.3 million to $0.3 million, or 49.5%, for
the second quarter of fiscal 2000 from $0.6 million for the same period a year
ago. Interest expense for the first six months in fiscal 2000 was $0.4 million
compared to $1.3 million, a decrease of 66.2%, for the comparable period in
fiscal 1999. The quarter and year-to-date decrease was primarily due to the
Company's lower overall debt level during the first six months of fiscal 2000 in
comparison to the same period a year ago.

        The effective tax rate for the second quarter and year-to-date of fiscal
year 2000 was 40.5% compared to 40.0% for the second quarter and year-to-date of
fiscal year 1999. The increase is due to a shift in the mix of earnings towards
countries with higher tax rates.

Year 2000

        In 1997, the Company created a corporate-wide Year 2000 project team
representing all business units of the Company. The "Year 2000 Issue" is the
result of computer programs being written using two digits rather than four to
define the applicable year. Any of the Company's computer programs that have a
time-sensitive software may recognize a date using "00" as the year 1900 rather
than the year 2000. The team was divided into three segments, each of which was
tasked with analyzing one of the following three sets of issues: (i) Year 2000
compliance issues with respect to Company internal information technology
systems and non-information technology systems; (ii) Year 2000 compliance issues
with respect to the information systems of certain key Company vendors and
suppliers; and (iii) Year 2000 compliance issues with respect to Company
products that the Company sells and licenses to its worldwide customer base.

        On the basis of information currently available, MICROS believes that it
did not experience any material problems relating to the Year 2000 issues. While
MICROS did uncover certain minor issues relating to date dependent data, none
were material and all were promptly addressed. Accordingly, the Year 2000 task
force has been disbanded, and any remaining issues that may surface will be
handled through the Company's customer service organization. Nonetheless, the
Company will continue to monitor products to attempt to assure that there are no
uncorrected problems. While the Company believes it has diligently addressed the
Year 2000 issues and that it has satisfactorily resolved any Year 2000 problems,
it is possible hitherto undetected problems could be uncovered in the future.

Year 2000 Compliance Costs

        To date, the Company has expensed all incremental costs related to the
Year 2000 analysis and remediation efforts. Internal and external costs
specifically associated with modifying software for the Year 2000 have been
charged to expense as incurred. All of these costs were funded through operating
cash flows. Management's current estimate (including the Year 2000 issues
identified to date) is that the costs associated with the Year 2000 issue should
not have a material adverse effect on the results of operations or financial
position of the Company in any given quarter. To date, not including the costs
incurred to upgrade the Company's internal management information systems, the
Company has incurred approximately $2.0 million in expenditures related to the
Year 2000 issue. Costs capitalized to date to implement the Company's new Year
2000 compliant internal management information systems, which address a large
variety of informational and processing needs, are approximately $7.4 million.

Euro Conversion

        On January 1, 1999, certain member nations of the European Economic and
Monetary Union ("EMU") adopted a common currency, the Euro. For a three-year
transition period, both the Euro and individual participants' currencies will
remain in circulation. After June 30, 2002, the Euro will be the sole legal
tender for EMU countries. The adoption of the Euro will affect a multitude of
financial systems and business applications as the commerce of these nations
will be transacted in the Euro and the existing national currency during the
transition period. As of December 31, 1999, of the eleven countries currently
admitted to the EMU, the Company has subsidiary operations in six of those
countries and distributor relationships in the remaining five countries.

        MICROS is currently addressing Euro related issues and its impact on
information systems, currency exchange rate risk, taxation, contracts,
competition and pricing. Action plans currently being implemented are expected
to result in compliance with all laws and regulations; however, there can be no
certainty that such plans will be successfully implemented or that external
factors will not have an adverse effect on the Company's operations. Moreover,
there is still some uncertainty with respect to the interpretation of certain
Euro regulations, and the impact of the regulations on the Company's Euro
implementation. Any costs associated with the adoption of the Euro will be
expensed as incurred and the Company currently does not expect these costs to be
material to its results of operations, financial condition or liquidity.

Liquidity and Capital Resources

        The Company has a $45.0 million multi-currency unsecured committed line
of credit, which was renewed during the second quarter of fiscal 2000 for an
additional one-year period, expiring on December 31, 2000. The line of credit
was increased from $35.0 million to $45.0 million pursuant to an amendment
entered into during the second quarter of fiscal 1999. The Company

has the one-time option to convert the line of credit into a three-year secured
term loan upon expiration of the line of credit. In addition, the Company has a
credit facility from a European bank in the amount of DM 15.0 million
(approximately $7.7 million at the December 31, 1999 exchange rate). Under the
terms of this facility, the Company may, at its option, borrow in the form of a
line of credit or in the form of term debt.

        As of December 31, 1999, the Company had borrowed approximately $2.6
million and has approximately $50.1 million available. There were no borrowings
under the line of credit. The Company's DM-denominated borrowings under these
credit facilities amounted to DM 5.0 million (approximately $2.6 million at the
December 31, 1999 exchange rate).

        As the Company has significant international operations, its
DM-denominated borrowings do not represent a significant foreign exchange risk.
On an overall basis, the Company monitors its cash and debt positions in each
currency in an effort to reduce its foreign exchange risk.

        Net cash provided by operating activities for the six months ended
December 31, 1999 was $22.2 million. The Company used $16.7 million in investing
activities, primarily for the purchase of acquisitions, purchase of an equity
interest and the purchase of property, plant and equipment. Net financing
activities for the first six months of fiscal 2000 provided $5.1 million,
primarily for the issuance of common stock.

        The Company anticipates that its cash flow from operations along with
available lines of credit, in conjunction with other lines of credit for which
the Company may be eligible or lines of credit to be renewed, are sufficient to
provide the working capital needs of the Company for the foreseeable future. The
Company anticipates that its property, plant and equipment expenditures for
fiscal 2000 will continue to increase approximately $6.0 million over fiscal
1999 expenditures, of which approximately $4.7 million will be for the purchase
of furniture and fixtures and leasehold improvements for its new headquarters
building.

Summary

        The Company has recently experienced rapid revenue growth at a rate that
it believes has significantly exceeded that of the global market for
point-of-sale computer systems and property management information systems
products for the hospitality industry. Although the Company currently
anticipates continued revenue growth at a rate in excess of such market, and
therefore an increase in its overall market share, it does not expect to
maintain growth at recent levels and there can be no assurance that any
particular level of growth can be achieved. In addition, due to the competitive
nature of the market, the Company continues to experience gross margin pressure
on its products and service offerings, and the Company expects this to continue.
There can be no assurance that the Company will be able to continue to increase
sufficiently sales of its higher margin products, including software and
services, to prevent future declines in the Company's overall gross margin.

        Moreover, some of the statements contained herein not based on historic
facts are forward-looking statements that involve risks and uncertainties. Past
performance is not necessarily a strong or reliable indicator of future
performance. Actual results could differ materially from past results, estimates
or projections. Some of the additional risks and uncertainties are: product
demand and market acceptance, including demand and acceptance for the new OPERA
products and the newest versions of the 3700 POS and 3400 QSR systems;
implementation of a cost-effective service structure capable of servicing
increasingly complex software systems in increasingly more remote locations;
achieving increased sales of higher margin software products; hiring and
retention of qualified employees with sufficient technical expertise; adverse
economic or political conditions; unexpected currency fluctuations; impact of
competitive products and pricing on margins; product development delays;
technological difficulties associated with new product releases, including those
with respect to the Fidelio next generation integrated property management and
central reservation system technologies; and controlling expenses. These and
other risks are disclosed in the Company's releases and SEC filings, including
in the section titled "Business and Investment Risks; Information Relating to
Forward-Looking Statements", in the Company's Annual Report on Form 10-K for the
Fiscal Year ended June 30, 1999.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk

        The Company has experienced rapid growth internationally. MICROS'
significant international business and presence does expose the Company to
certain market risks, such as currency, interest rate and political risks. With
respect to currency risk, the Company transacts business in over 26 different
currencies through its foreign subsidiaries. The fluctuation of currencies
impacts sales and profitability. Frequently, sales and the costs associated with
such sales are not always denominated in the same currency. Given the fact that
the Company transacts business in many different currencies, adverse declines in
certain currencies can be offset by favorable advances in other currencies.
While the Company has not to date invested in financial instruments designed to
protect against currency fluctuations, the Company will continue to evaluate the
need to do so in the future.

        Additionally, the Company is subject to interest rate fluctuations in
foreign countries to the extent that the Company elects to borrow in the local
foreign currency. In the past, this has not been an issue of concern as the
Company has the capacity to elect to borrow in other currencies with more
favorable interest rates. While the Company has not to date invested in
financial instruments designed to protect against interest rate fluctuations,
the Company will continue to evaluate the need to do so in the future.

        Further, the Company is subject to political risk, especially in
developing countries with uncertain or unstable political structures or regimes.
The Company is also subject to the effects of, and changes in, laws and
regulations, other activities of governments, agencies and similar
organizations, especially in light of the current weak Asian economic
conditions, which may prompt certain legislative reform. The Company does not
believe at this time that it is exposed to unusual political risk that could
have a material adverse impact on the Company.

        Finally, the Company's unsecured committed line of credit bears interest
at a floating rate of interest. It does not invest in financial instruments
designed to protect against interest rate fluctuations, although it will
continue to evaluate the need to do so in the future.

                           Part II - Other Information


Item 1.     Legal Proceedings

        MICROS is and has been involved in legal proceedings arising in the
normal course of business. The Company is of the opinion, based upon presently
available information and the advice of counsel concerning pertinent legal
matters, that any resulting liability should not have a material adverse effect
on the Company's results of operations or financial position.

        On March 25, 1997, Budgetel Inns, Inc. ("Budgetel") filed suit against
MICROS in the United States Federal District Court in the Eastern District of
Wisconsin. Budgetel alleges, among other things, that MICROS breached a March
1993 software support agreement by failing to provide full support to this
software package licensed to Budgetel in 1993. MICROS filed its answer to the
complaint in September of 1999. MICROS also filed a counterclaim against
Budgetel, alleging breach of contract and defamation. The litigation is
currently in the discovery phase. While the ultimate outcome of litigation is
uncertain, and while litigation is inherently difficult to predict, the Company
is of the opinion, based upon presently available information and the advice of
counsel concerning pertinent legal matters, that resulting liability, if any,
should not have a material adverse effect on the Company's results of operations
or financial position.

Items 2 and 3.  Changes in Securities and Use of Proceeds

        No events occurred during the quarter covered by the report that would
require a response to this item.

Item 4.     Submission of Matters to a Vote of Security Holders

        The annual meeting of shareholders was held on November 19, 1999. A
