1.   BASIS OF PRESENTATION

     The information at December 31, 1998 and 1999 and for the three month
periods then ended is unaudited, but includes all adjustments (consisting only
of normal recurring entries) which the Company's management believes to be
necessary for the fair presentation of the financial position, results of
operations, and changes in cash flows for the periods presented. The
accompanying interim condensed consolidated financial statements should be read
in conjunction with the financial statements and related notes included in the
Company's Annual Report on Form 10-K for the fiscal year ended September 30,
1999. Certain information and notes normally included in financial statements
prepared in accordance with generally accepted accounting principles have been
condensed or omitted pursuant to the Securities and Exchange Commission rules
and regulations. Interim results of operations for the three month period ended
December 31, 1999 are not necessarily indicative of operating results for the
full fiscal year.

2.   STOCK REPURCHASE PROGRAM

     In February 1998, the Company announced that it would be initiating a stock
repurchase program of up to $6,000 of common stock to use to meet requirements
of its employee stock option and stock purchase plans. No minimum number or
value of shares to be repurchased has been fixed nor has a time limit as to the
duration of the program been established.

     On October 29, 1999, the Company's Board of Directors approved a new stock
repurchase program authorizing the Company to repurchase an additional $10,000
of common stock to use to meet requirements of its employee stock option and
stock purchase plan. No minimum number or value of shares to be repurchased has
been fixed for the new program nor has a time limit as to the duration of the
program been established.

     No shares were repurchased by the Company during the quarter ended December
31, 1999 under either of the repurchase plans. The Company reissued 125 shares
which had been purchased under the February 1998 Plan during the quarter ended
December 31, 1999.

4.   NET INCOME PER COMMON SHARE

     In February, 1997, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 128 (SFAS 128), Earnings per
Share. This Statement, which the Company adopted with the quarter ended December
31, 1997, establishes and simplifies standards for computing and presenting
earnings per share. SFAS 128 requires restatement of all previously reported
earnings per share data that are presented.

     Basic earnings per share is determined by dividing net income applicable to
common stockholders by the weighted average number of common shares outstanding
during the period. Diluted earnings per share is determined by dividing net
income applicable to common stockholders by the weighted average number of
common shares and common share equivalents outstanding during the period. Common
share equivalents are included in the diluted earnings per share calculation
when dilutive. Common share equivalents consisting of common stock issuable upon
exercise of outstanding common stock options are computed using the treasury
stock method.

     The computation of basic and diluted earnings per share for the three
months ended December 31, 1998 and 1999 is as follows:

5.   SEGMENT INFORMATION AND GEOGRAPHIC AREAS

     Effective October 1, 1998, the Company adopted Statement of Financial
Accounting Standards No. 131 (SFAS 131), Disclosures About Segments of an
Enterprise and Related Information. SFAS 131 superceded Statement of Financial
Accounting Standards No. 14 (SFAS 14), Financial Reporting for Segments of a
Business Enterprise. SFAS 131 establishes standards for disclosures about
operating segments, products and services, geographic areas, and major
customers. Management has determined that the Company operates in one industry
segment: the design, development, sale, service, and support of proprietary
software products. Substantially all of the Company's revenues are derived from
the licensing of software products and providing related consulting, support,
and training services.

       ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                            AND RESULTS OF OPERATIONS

     All statements contained herein that are not historical facts, including
but not limited to, statements regarding anticipated future revenue and expense
levels and capital requirements, the Company's future product development and
marketing plans, the Company's ability to generate cash from operations, and the
Company's ability to attract and retain employees, are based on current
expectations. These statements are forward looking in nature, involve a number
of risks and uncertainties, as more fully described under "Factors Affecting
Future Performance" and are made pursuant to the Private Securities Litigation
Reform Act of 1995. Actual results may differ materially from those described in
the forward-looking statements.

RESULTS OF OPERATIONS

     The Company's revenue is derived from two sources: software license fees
and services revenue. Software license fees include revenue from non-cancelable
software license agreements entered into between the Company and its customers
with respect to both the Companies' products and third party products marketed
and/or distributed by the Company. The Company's service revenue is comprised of
software maintenance fees and fees for consulting and training services.
Maintenance revenue is recognized ratably over the maintenance period.
Consulting service revenue is recognized as the services are performed.

     The following table sets forth for the periods indicated the Company's
condensed consolidated statement of operations data expressed as a percentage of
total revenue and the percentage of dollar increase period over period for the
three months ended December 31, 1998 and 1999:

QUARTER ENDED DECEMBER 31, 1999 COMPARED TO QUARTER ENDED DECEMBER 31, 1998

     REVENUE. Total revenue decreased 22%, from $30.1 million for the quarter
ended December 31, 1998 to $23.5 million for the quarter ended December 31,
1999. The Company believes that the decrease was primarily due to potential
customers deciding to postpone software acquisitions to focus on their internal
Year 2000 compliance issues.

     Revenue in North America (United States and Canada) including the Cort
Payroll Unit decreased 21%, from $27.7 million for the quarter ended December
31, 1998 to $21.7 million for the quarter ended December 31, 1999. This is
representative of 93% of total revenue for the first quarter of fiscal year 2000
compared to 92% of total revenue for the first quarter of fiscal year 1999. EMEA
(Europe, Middle East and Africa) revenue decreased 15% from $2.0 million for the
quarter ended December 31, 1998 to $1.7 million for the quarter ended December
31, 1999 while its percentage of total revenue remained unchanged at 7%. Other
international regions, including Asia-Pacific and Latin America, contributed
less than 1% of total revenue for the first quarter of fiscal year 1999 and less
than 2% for the first quarter of fiscal year 1998.

     Software license fee revenue decreased 56%, from $8.5 million for the
quarter ended December 31, 1998 to $3.8 million for the quarter ended December
31, 1999. The Company believes the decrease was primarily due to potential
customers deciding to postpone software acquisitions to focus on their internal
Year 2000 compliance issues.

     Service revenue decreased 8%, from $21.5 million for the quarter ended
December 31, 1998 to $19.8 million for the quarter ended December 31, 1999. This
decrease was due primarily to a decrease in demand for the Company's service
offerings due to lower software license fees.

     The table below summarizes the composition of and decrease in the Company's
services revenue.

</TABLE>

     COST OF SOFTWARE LICENSE FEES. Cost of software license fees consists
primarily of royalties on the sale of third party products, amortization expense
related to capitalized software and the cost of product media, manuals and
shipping. Cost of software license fees decreased 19%, from $1.9 million for the
quarter ended December 31, 1998 to $1.6 million for the quarter ended December
31, 1999. Cost of software license fees as a percentage of software license fee
revenue increased from 23% for the quarter ended December 31, 1998 to 42% for
the quarter ended December 31, 1999. The decrease in the dollar amount was
primarily due to a decrease in royalties on third party product software sales.

     COST OF SERVICES. Cost of services consists of costs to provide product and
technical support, consulting services and training services to licensees of the
Company's software products. Cost of services decreased 8%, from $9.5 million
for the quarter ended December 31, 1998 to $8.7 million for the quarter ended
December 31, 1999. Cost of services as a percentage of service revenue remained
constant at 44% for the quarters ended December 31, 1998 and 1999. The decrease
in the dollar amount is due to lower third party consulting fees. For the
quarter ended December 31, 1999, the cost of services relating to the
discontinued product lines was $923 (see Note 7 to the condensed consolidated
financial statements).

     RESEARCH AND DEVELOPMENT. Research and development expenses consist
primarily of engineering personnel, related facilities and computer and
communications overhead, and third party contractor costs reduced by capitalized
software development costs and, when applicable, research funding. Research and
development expenses decreased 5% from $5.3 million for the quarter ended
December 31, 1998 to $5.0 million for the quarter ended December 31, 1999.
Research and development expense as a percentage of total revenue was 17% for
the fiscal year ended December 31, 1998 and 21% for the fiscal year ended
December 31, 1999. The decrease in the dollar amount is due to a reduction of
development costs related to the Infinium Financials for Windows NT and Infinium
Human Resources for Windows NT products. The Company decided to discontinue new
release development for those products in September 1999. For the quarter ended
December 31, 1999, the research and development expense relating to the
discontinued


                                       11
<PAGE>   12


product lines was $1,177 (see Note 7 to the condensed consolidated financial
statements).

     SALES AND MARKETING. Sales and marketing expenses consist primarily of
salaries, commissions, travel, promotional expenses, facilities and computers
and communications costs for direct sales offices. Sales and marketing expenses
decreased 16% from $9.9 million for the quarter ended December 31, 1998 to $8.3
million for the quarter ended December 31, 1999. The decrease was primarily due
to a decrease in commission expense associated with lower revenue. Sales and
marketing expense as a percentage of total revenue was 33% and 35% for the first
quarter of fiscal year 1999 and fiscal year 2000, respectively.

     GENERAL AND ADMINISTRATIVE. General and administrative expenses consist
primarily of salaries of executive and administrative personnel and related
facilities and computers and communication overhead, as well as provisions for
doubtful accounts, insurance, investor relations and outside professional fees.
General and administrative expenses increased 13% from $2.4 million for the
quarter ended December 31, 1998 to $2.7 million for the quarter ended December
31, 1999. General and administrative expense as a percentage of total revenue
was 8% and 12% for the first quarter of fiscal year 1999 and fiscal year 2000,
respectively. The increase in dollar amount was primarily due to a slight
increase in staffing and higher outside professional fees.

     PROVISION FOR INCOME TAXES. The provision for federal, state and foreign
income changed from $0.5 million representing an effective income tax rate of
32% for the quarter ended December 31, 1998 to a tax benefit of $0.9 million
representing an effective income tax rate of 37% for the quarter ended December
31, 1999.

LIQUIDITY AND CAPITAL RESOURCES

     As of December 31, 1999, the Company had cash, cash equivalents and
marketable securities of $39.4 million resulting from a net use of cash, cash
equivalents and marketable securities of $7.8 million during the first three
months of fiscal year 2000. Operating activities consumed $6.4 million, $0.6
million was used to fund capitalized software, $0.7 was used for purchases of
computers and equipment and the acquisition of iT-Soft consumed an additional
$0.7 million. Proceeds from the exercise of stock options and employee stock
purchase plan provided $0.7 million.

     Days sales outstanding ("DSO") increased to 62 days at December 31, 1999
compared to 47 days at September 30, 1999. The Company calculates DSO by
dividing the ending accounts receivable balance, net of allowance for doubtful
accounts, by the annualized revenue for the quarter, multiplied by 360. The
Company believes that this method of deriving DSO is indicative of actual
results due to the cyclical nature of software license and service transactions,
which are often consummated nearer the end of the quarter, as well as the
fluctuation of transactions from one quarter to the next. The increase in DSO is
primarily due to the decrease in revenue for the quarter ended December 31,
1999.

     Deferred revenue decreased $1.9 million, from $37.8 million at September
30, 1999 to $35.9 million at December 31, 1999. The decrease in deferred revenue
primarily resulted from a decrease in the deferred consulting services component
due to lower customer bookings during the quarter ended December 31, 1999.

     The Company believes that cash, cash equivalents and marketable securities
on hand and cash flows from operations will be sufficient to fund its operations
at least through fiscal 2000. While operating activities may provide cash in
certain periods, to the extent the Company experiences growth in the future, the
Company anticipates that its operating and investing activities may use cash,
and consequently, such growth may require the Company to obtain additional
sources of financing.

IMPACT OF THE YEAR 2000

The Year 2000 issue relates primarily to computer software and operating systems
in which dates have been abbreviated. Unless corrected, these systems may
recognize the date of "January 1, 2000" as "January 1, 1900." As a result,
computer software and operating systems used by many companies may need to be


                                       12
<PAGE>   13


upgraded to comply with Year 2000 requirements. The Company instituted a Year
2000 project in which Year 2000 issues were assessed and addressed in the
development of its software systems, its relationships with third parties, and
its internal operating systems.

Since the end of calendar 1999, the Company has not experienced any material
issues or failures related to the Year 2000.

FACTORS AFFECTING FUTURE PERFORMANCE

The factors affecting the Company's future performance have not changed
significantly from those enumerated in the Company's Annual Report on Form 10-K
for the year ended December 31, 1999.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The following discussion about the Company's market risk involves
forward-looking statements. Actual results could differ materially from those
discussed in the forward-looking statements. The Company is exposed to market
risk related to changes in interest rates and foreign currency exchange rates.
The Company does not use derivative financial instruments for speculative or
trading purposes.

INTEREST RATE RISK
The Company is exposed to market risk from changes in interest rates primarily
through its investing and borrowing activities. In addition, the Company's
ability to finance future acquisition transactions may be impacted if the
Company is unable to obtain appropriate financing at acceptable rates. The
Company's investing strategy to manage interest rate exposure is to invest in
short-term, highly liquid investments. The Company maintains a portfolio of
highly liquid cash equivalents and short-term investments. At December 31, 1999,
the fair value of the Company's short-term investments approximated market
value.

FOREIGN CURRENCY RISK
The Company faces exposure to movements in foreign currency exchange rates.
These exposures may change over time as business practices evolve and could have
a material adverse effect on the Company's business, financial condition and
results of operations. The Company does not use derivative financial instruments
to hedge foreign currency exposures or for trading. Historically, the Company's
primary exposures have been related to the operations of its foreign
subsidiaries. In the quarter ended December 31, 1999, the net impact of foreign
currency changes was not material. The introduction of the Euro as a common
currency for most members of the European Monetary Union took place in the
Company's fiscal year 1999.
