                          PLATINUM SOFTWARE CORPORATION

         NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                DECEMBER 31, 1997


BASIS OF PRESENTATION

The accompanying unaudited condensed consolidated financial statements present
the financial position of Platinum Software Corporation (the "Company") as of
December 31, 1997 and June 30, 1997, the results of its operations for the three
and six months ended December 31, 1997 and 1996, and its cash flows for the six
months ended December 31, 1997 and 1996, and have been prepared by the Company
in accordance with generally accepted accounting principles and pursuant to the
rules and regulations of the Securities and Exchange Commission (the "SEC").
Certain information and footnote disclosures normally included in the financial
statements prepared in accordance with generally accepted accounting principles
have been condensed or omitted pursuant to such rules and regulations, although
the Company believes that the disclosures in these financial statements are
adequate to make the information presented not misleading. The unaudited
condensed consolidated financial statements should be read in conjunction with
the financial statements and notes thereto included in the Company's Annual
Report on Form 10-K for the year ended June 30, 1997.

In the opinion of management, the unaudited condensed consolidated financial
statements contain all adjustments (consisting only of normal recurring
adjustments) necessary for a fair presentation of the Company's financial
position, results of operations and cash flows.

The results of operations for the six months ended December 31, 1997, are not
necessarily indicative of the results of operations to be expected for the
entire fiscal year ending June 30, 1998.

REVENUE RECOGNITION

Revenue is recognized from licenses of software upon contract execution,
shipment of products and when the Company has performed all of its significant
contractual obligations. When a software license agreement obligates the Company
to provide more than one software module, all license revenue under the
agreement is deferred until all modules achieve general availability and are
delivered, except when the license agreement contains a specific financial
remedy in the event the unavailable module is not delivered. In such instance,
revenue is deferred in the amount attributable to the specific financial remedy.
The Company generally does not provide any post-contract customer service or
support as part of the software license fee; however, when such services are
provided for in the license agreement, an appropriate portion of the license fee
is deferred and amortized over the service or support period. The Company's
customers may enter into maintenance agreements with the Company and such
revenue is recognized ratably over the term of the agreement. Revenue from
consulting services is recognized as services are provided.

BASIC AND DILUTED NET INCOME (LOSS) PER SHARE

In 1997, the Financial Accounting Standards Board issued Statement of Financial
Accounting Standards No. 128, Earnings Per Share. Statement 128 replaced the
previously reported primary and fully diluted earnings per share with basic and
diluted earnings per share. Basic net income (loss) per share is computed by
dividing net income (loss) by the weighted average number of shares of common
stock outstanding during the period. Diluted income (loss) per share is computed
by dividing net income (loss) by the weighted average number of shares of common
stock and common stock equivalents outstanding during the period. Common stock
equivalents were antidilutive for the three and six months ended December 31,
1996, and, therefore, excluded from the calculation of diluted net loss per
share for such periods. All earnings per share amounts for all periods have been
presented and, where necessary, restated to conform with the provisions of
Statement 128.

FISCAL 1998 ACQUISITION

On November 14, 1997, the Company acquired FocusSoft, Inc. ("FocusSoft"), a
privately held provider of enterprise resource planning and distribution
software based in Louisville, Kentucky. The acquisition was structured as a
triangular merger whereby FocusSoft became a wholly owned subsidiary of the
Company. As consideration for the acquisition, the Company issued 2,474,794
shares of common stock in exchange for all of the outstanding shares of common
stock of FocusSoft. The exchange ratio used with respect to the FocusSoft shares
was 24.747937 (i.e., each share of FocusSoft common stock converted into
24.747937 shares of the Company's common stock.) In addition, the Company
assumed all of the employee stock options of FocusSoft, which translated into
stock options to acquire 225,206 shares of common stock of the Company. Ten
percent of the shares issued in the merger, or 247,480 shares, were placed into
an escrow for a period of one year to cover indemnification claims in connection
with the transaction. The transaction was accounted for as a pooling of
interests, and accordingly, the accompanying condensed consolidated financial
statements have been restated to incorporate the financial position, results of
operations and cash flows of FocusSoft for all periods presented.

FISCAL 1997 ACQUISITION

On June 30, 1997 the Company acquired Clientele Software, Inc. ("Clientele") a
privately held provider of help desk automation software based in Portland,
Oregon. As consideration for the acquisition, the Company issued 887,636 shares
of common stock in exchange for all of the outstanding shares of common stock of
Clientele. The exchange ratio used with respect to the conversion of the
Clientele shares was .19761 (i.e., each share of Clientele common stock
converted into .19761 shares of the Company's common stock). In addition, the
Company assumed all of the outstanding employee stock options of Clientele,
which translated into stock options to acquire 212,356 shares of common stock of
the Company. Ten percent of the shares issued in the merger, or 88,764 shares,
were placed into an escrow for a period of one year to cover indemnification
claims in connection with the transaction. The transaction was accounted for as
a pooling of interests, and accordingly, the accompanying condensed consolidated
financial statements have been restated to incorporate the financial position,
results of operations and cash flows of Clientele for all periods presented.

FISCAL 1996 AND 1997 RESTRUCTURINGS

During the second quarter of fiscal 1996, the Company restructured its business
operations. The restructuring included the cessation of the marketing of the
version of the Company's Platinum SQL Enterprise product that runs on the
Sybase/UNIX server platform as well as the elimination of the Company's direct
sales force for its Platinum SQL Enterprise product line. The restructuring
resulted in a charge of $3.3 million which was recorded in the second quarter of
fiscal 1996. Such amount included approximately $1.2 million for severance and
other extended benefit costs related to the reduction in force, $1.2 million for
lease termination and buyout costs related to the closure of facilities and
$872,000 in asset write-downs and other costs.

In February 1996, the Company had another reduction in force of approximately 40
people. This reduction in force resulted in an additional restructuring charge
of $2.3 million which was recorded in the third quarter of fiscal 1996. Such
amount included approximately $300,000 for severance and other extended benefit
costs related to the reduction in force, $625,000 in lease termination and
buyout costs related to the closure of facilities and $1.4 million in asset
write-downs and other costs.

In June 1997, the Company underwent another restructuring as a result of the
Clientele acquisition. This resulted in an additional restructuring charge of
$1.6 million which was recorded in the fourth quarter of fiscal 1997. Such
amount included approximately $1.1 million for excess facility costs, as well as
approximately $500,000 for severance and other extended benefit costs. During
the six months ended December 31, 1997, the Company paid approximately $636,000
for severance, lease termination and other costs relating to the 1996 and 1997
restructurings.

CONTINGENCIES

The Company is subject to miscellaneous legal proceedings in the normal course
of business and other legal proceedings. The Company is currently defending
these proceedings and claims, and anticipates that it will be able to resolve
these matters in a manner that will not have a material adverse effect on the
Company's financial position, results of operations or cash flows.

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

RESULTS OF OPERATIONS

Net income for the second quarter of fiscal 1998 was $2.0 million, or $0.07 per
share, as compared to a net loss of $581,000, or $(0.03) per share, for the
comparable quarter of fiscal 1997. Net income for the first six months of fiscal
1998 was $3.3 million or $0.11 per share, as compared to a net loss of $2.7
million, or $(0.12) per share, for the comparable period of fiscal 1997. The
following summarizes the significant aspects related to the Company's results of
operations.

Revenues

Revenues were approximately $21.7 million and $14.3 million for the three months
ended December 31, 1997 and 1996, respectively, representing an increase of 52%.
Revenues were approximately $39.9 million and $26.4 million for the six months
ended December 31, 1997 and 1996, respectively, representing an increase of 51%.
The increase for the three and six months ended December 31, 1997 reflected a
general increase in license and service revenues, as discussed below.

Total license fee revenues were approximately $11.7 million and $7.7 million for
the three months ended December 31, 1997 and 1996, respectively, representing an
increase of 51% and approximately $21.7 million and $13.7 million for the six
months ended December 31, 1997 and 1996, respectively, representing an increase
of 59%.

License fee revenues for the Company's Platinum SQL product were approximately
$7.0 million and $4.3 million for the three months ended December 31, 1997 and
1996, respectively, representing an increase of 61% and approximately $12.5
million and $7.6 million for the six months ended December 31, 1997 and 1996,
respectively, representing an increase of 65%. The increases resulted primarily
from the re-establishment of the Company's direct sales force, an overall
increase in personnel in the direct sales force, additional direct mail
marketing campaigns and an increased effort to sell Platinum SQL
internationally.


                                       8

License fee revenues for the Platinum for DOS and Platinum for Windows products
were approximately $1.7 million and $2.0 million for the three months ended
December 31, 1997 and 1996, respectively, representing a decrease of 12% and
approximately $3.7 million and $3.5 million for the six months ended December
31, 1997 and 1996, respectively, representing an increase of 5%. The increase
for the six months ended December 31, 1997 resulted primarily from increased
domestic demand created by the commercial availability of a complete suite of
Platinum for Windows core modules during the quarter ended December 31, 1997.
The complete set of Platinum for Windows core modules were first available in
December 1996. The decrease for the three months ended December 31, 1997
resulted primarily from the increased effort to sell and provide Platinum SQL as
the preferred financial application solution internationally due in part to the
Company's decision not to complete the localizations of the Platinum for DOS and
Platinum for Windows products.

License fee revenues for the Clientele products were approximately $1.9 million
and $1.0 million for the three months ended December 31, 1997 and 1996,
respectively, representing an increase of 96% and approximately $3.4 million and
$1.8 million for the six months ended December 31, 1997 and 1996, respectively,
representing an increase of 85%. The increases resulted primarily from the
increased experience and expertise of the Company's telesales employees, the
addition of a direct sales force, as well as the telesales and marketing efforts
during the three and six months ended December 31, 1997.

License fee revenues for the Platinum SQL Advanced Distribution and Advanced
Manufacturing applications (formerly named FocusSoft Millenia) were
approximately $1.0 million and $199,000 for the three months ended December 31,
1997 and 1996, respectively, representing an increase of 396% and approximately
$2.1 million and $263,000 for the six months ended December 31, 1997 and 1996,
respectively, representing an increase of 636%. The increases resulted from the
expansion of the direct sales force, the release of version 5.0 of the product
with enhanced distribution and manufacturing functionality, increased marketing
efforts and additional relationships with financial application vendors
recommending the products.

International license fee revenues were approximately $3.0 million and $2.2
million for the three months ended December 31, 1997 and 1996, respectively,
representing an increase of 36% and approximately $5.7 million and $3.9 million
for the six months ended December 31, 1997 and 1996, respectively, representing
an increase of 46%. The increases were primarily due to the increases in license
fee revenues for all of the Company's products as well as increased sales
efforts in the international markets for the Platinum SQL product as described
above.

Consulting and professional services revenue increased 112% from revenues of
$2.6 million in the three months ended December 31, 1996 to $5.6 million in the
three months ended December 31, 1997 and increased 93% from revenues of $5.0
million in the six months ended December 31, 1996 to $9.7 million in the six
months ended December 31, 1997. The increase in the three and six months ended
December 31, 1997 was primarily attributable to the Company's increased focus in
late fiscal 1997 and fiscal 1998 on providing consulting and implementation
services to customers and an effort to increase the utilization of professional
services personnel.

Support services revenue increased 13% from revenues of $3.8 million in the
three months ended December 31, 1996 to $4.3 million in the three months ended
December 31, 1997 and increased 12% from revenues of $7.4 million in the six
months ended December 31, 1996 to $8.3 million in the six months ended December
31, 1997. The increases were primarily attributable to an overall rise in the
installed base of end-users of Platinum SQL and an increased effort to renew
customers on maintenance contracts which effort the Company commenced in early
fiscal 1997.

Gross Profit

Gross profit increased as a percentage of revenues from 65% for the three months
ended December 31, 1996 to 67% for the three months ended December 31, 1997.
Gross profit increased as a percentage of revenues from 64% for the six months
ended December 31, 1996 to 67% for the six months ended December 31, 1997. The
increase in gross profit percentage was primarily due to higher license fee
revenues as a percentage of total revenues, which have higher margins than
consulting and professional services revenues.


                                       9

<PAGE>   10

Operating Expenses

Total operating expenses increased from $10.0 million for the three months ended
December 31, 1996 to $13.0 million for the three months ended December 31, 1997.
Total operating expenses increased from $19.9 million for the six months ended
December 31, 1996 to $24.5 million for the six months ended December 31, 1997.
The increases were primarily attributable to the re-establishment of a direct
sales force for the Company's Platinum SQL product which commenced in the fourth
quarter of fiscal 1996 and an overall increase in direct sales and professional
services personnel. Total operating expenses as a percentage of revenues were
60% and 70% for the three months ended December 31, 1997 and 1996, respectively.
Total operating expenses as a percentage of revenues were 61% and 76% for the
six months ended December 31, 1997 and 1996, respectively. Included in operating
expenses for the three and six months ended December 31, 1997 were approximately
$800,000 in one-time charges for the FocusSoft acquisition. See "Notes to
Unaudited Condensed Consolidated Financial Statements."

Sales and marketing expenses were approximately $7.8 million and $6.0 million
for the three months ended December 31, 1997 and 1996, respectively, or
approximately 36% and 42% of total revenues. Sales and marketing expenses were
approximately $15.0 million and $11.5 million for the six months ended December
31, 1997 and 1996, respectively, or approximately 38% and 44% of total revenues.
The dollar amount increases resulted from the growth of the direct sales force
for the Company's Platinum SQL product.

General and administrative expenses were approximately $2.1 million and $1.6
million for the three months ended December 31, 1997 and 1996, respectively, or
approximately 10% and 11% of total revenues. General and administrative expenses
were approximately $3.4 million and $3.6 million for the six months ended
December 31, 1997 and 1996, respectively, or approximately 9% and 14% of total
revenues. Included in the three and six months ended December 31, 1997 were
approximately $800,000 of one-time acquisition costs related to the FocusSoft
acquisition. Excluding the acquisition costs, the decreases were primarily due
to the reduction of legal reserves of $500,000 from the six months ended
December 31, 1996 to the six months ended December 31, 1997, and the increase in
the fair value of a note receivable from a divestiture as part of the fiscal
1994 restructuring which was previously written off, which were offset in part
by an increase in the provision for additional bad debts.

Software development expenditures were approximately $3.2 million and $2.7
million for the three months ended December 31, 1997 and 1996, respectively,
before capitalization of software costs of approximately $130,000 and $269,000,
respectively. Software development expenditures were approximately $6.3 million
and $5.6 million for the six months ended December 31, 1997 and 1996,
respectively, before capitalization of software costs of approximately $251,000
and $769,000, respectively. Upon the release for general availability of the
Company's software products, the Company amortizes capitalized software
development costs over a five year period. Such amortization is included in cost
of revenues. The percentage of capitalized software development costs to total
software development costs was 4% for the three months ended December 31, 1997
and 10% for the three months ended December 31, 1996. The percentage of
capitalized software development costs to total software development costs was
4% for the six months ended December 31, 1997 and 14% for the six months ended
December 31, 1996. During the three and six months ended December 31, 1997,
costs were capitalized for the creation of translations into different languages
for the Platinum SQL and Platinum for Windows products and for the Job Cost
module for Platinum for Windows and Job Shop and Engineer to Order for the
Platinum SQL Advanced Distribution and Advanced Manufacturing applications.
During the three and six months ended December 31, 1996, costs were capitalized
for the multi-currency functionality for Platinum SQL.

Other Income

Other income for the three months ended December 31, 1997 and 1996, was
approximately $565,000 and $143,000, respectively. Other income for the six
months ended December 31, 1997 and 1996, was approximately $1.1 million and
$342,000, respectively. The increase primarily resulted from additional interest
earned on the Company's cash and cash equivalents and short-term investments,
and an increase of $298,000 in the fair value of an investment.

Provision for Income Taxes

The Company has not provided a provision for income taxes for the quarter ended
December 31, 1997 due to the Company's utilization of operating loss
carryforwards. A valuation allowance had been provided against such operating
loss carryforwards.

Year 2000 Problems of Third Parties

It is possible that the currently installed computer systems, software products
or other business systems of the Company's distributors, resellers, suppliers,
manufacturers or customers, working either alone or in conjunction with other
software systems, will not accept input of, store, manipulate and output dates
in the Year 2000 or thereafter without error or interruption (the "Year 2000
Problem"). The Company's software products are not subject to the Year 2000
Problem, however, the Company is querying its distributors, resellers,
suppliers, manufacturers and customers as to their progress in identifying and
addressing Year 2000 Problems. The expenses of the Company's efforts or the
expenses or liabilities to which the Company may become subject as a result of
such problems, are not expected to have a material adverse effect on the
Company's business, results of operations, cash flows and financial condition.

FINANCIAL CONDITION

Liquidity and Capital Resources

As of December 31, 1997, the Company's principal sources of liquidity included
cash and cash equivalents of approximately $4.5 million. Cash and cash
equivalents decreased by approximately $2.3 over the June 30, 1997 balance
primarily due to cash used in operations principally from significant cash
outlays in the first six months of fiscal 1998 for the fiscal 1997 year-end
sales and professional services commissions owed and for costs related to the
FocusSoft acquisition. The Company had working capital of $3.8 million at June
30, 1997 as compared to working capital of $8.2 million at December 31, 1997.
The increase was primarily attributable to the increase in accounts receivable
and to the reduction of accounts payable and accrued expenses.

The Company paid approximately $636,000 in severance, lease and other costs
related to the fiscal 1996 and 1997 restructurings during the six months ended
December 31, 1997. At December 31, 1997, the Company had a $2.0 million cash
obligation related to lease termination and other costs of the fiscal 1996 and
1997 restructurings. These obligations will be funded from existing cash
reserves, working capital and operations.

The Company has taken steps to significantly reduce its operating expenses,
through several reductions in work force over the past two years, as well as the
disposition of several business units. In connection with such restructurings
the Company will incur additional cash outlays of approximately $2.0 million.
See "Fiscal 1996 and 1997 Restructurings." If the Company is not successful in
achieving targeted revenues or positive cash flow from operations, the Company
may be required to take actions to align its operating expenses with its reduced
revenues, such as reductions in work force, or other expense cutting measures or
seeking additional debt or equity financing. There can be no assurance that the
Company would be able to reduce expenses or secure additional financing on
reasonable terms or at all.

The Company is dependent upon its ability to generate cash flow from license
fees and other operating revenues, as well as the collection of its outstanding
accounts receivable to maintain current liquidity levels. The Company believes
that its current cash reserves, together with existing sources of liquidity,
will satisfy the Company's projected short-term liquidity and other cash
requirements for the next 12 months.

CERTAIN FACTORS THAT MAY AFFECT FUTURE RESULTS

        FORWARD LOOKING STATEMENTS. This quarterly report contains certain
forward looking statements within the meaning of Section 27A of the Securities
and Exchange Act of 1933, as amended, and Section 21E of the Securities and
Exchange Act of 1934, as amended, that involve risks and uncertainties. In
addition, the Company may from time to time make oral forward looking
statements. Actual results are uncertain and may be impacted by the following
factors, among others, which may cause the actual results to differ materially
from those projected in the forward looking statement. Because of these and
other factors that may affect the Company's operating results, past performance
should not be considered an indicator of future performance and investors should
not use historical results to anticipate results or trends in future periods.


                                       11

        LIQUIDITY. The Company's cash and cash equivalents decreased from $6.7
million at June 30, 1997 to $4.5 million at December 31, 1997, principally due
to cash used in operations. The Company incurred significant cash outlays in the
first six months of fiscal 1998 for fiscal 1997 year-end sales and professional
services commissions and for costs related to the FocusSoft acquisition. In
addition, there will be further cash outlays estimated at approximately $614,000
in connection with the second quarter fiscal 1996 restructuring, $126,000 in
connection with the third quarter fiscal 1996 restructuring and $1.2 million in
connection with the fiscal 1997 restructuring. If the Company is not successful
in achieving targeted revenues or positive cash flow from operations, the
Company may be required to take actions to align its operating expenses with its
reduced revenues, such as reductions in work force or other expense cutting
measures, or seek additional debt or equity financing. There can be no assurance
that the Company would be able to reduce expenses or secure additional financing
on reasonable terms or at all.

        FLUCTUATIONS IN QUARTERLY OPERATING RESULTS. The Company's operating
results can vary substantially from period-to-period. The Company's quarterly
operating results fluctuate in part due to the number and timing of new product
introductions and enhancements, discontinuance of product lines, the timing of
product orders and shipments, recognition of deferred revenue upon the Company's
completion of its contractual obligations, marketing and product development
expenditures and promotional programs. A significant portion of the Company's
quarterly revenues are recorded in the final month of the quarter, with a
concentration of such revenues in the final 10 business days of that month.
Also, the timing of the closing of direct sales in the latter part of each
quarter increases the risk of quarter-to-quarter fluctuations. Accordingly, the
Company believes that period-to-period comparisons of its results of operations
are not necessarily meaningful and should not be relied upon as an indication of
future performance. If revenues do not meet the Company's expectations in any
given quarter, operating results may be adversely affected. There can be no
assurance that the Company will be profitable in any quarter or at all.

        HORIZONTAL PRODUCT STRATEGY. As part of its business strategy, the
Company intends to expand its product offerings to include application software
products that are complementary to financial accounting, manufacturing and
distribution, sales force automation and help desk applications. This strategy
may involve acquisitions, investments in other businesses that offer
complementary products, joint development agreements or licensing of technology
agreements. See "Fiscal 1997 Acquisition" and "Fiscal 1998 Acquisition" in the
Notes to the Unaudited Condensed Consolidated Financial Statements. Such
acquisitions are, and any future acquisitions or investments would be
accompanied by the risks commonly encountered in the acquisitions of businesses.
Some of these risks include, among other things, the integration of previously
distinct businesses into one business unit, the substantial management time
devoted to such activities, the potential disruption of the Company's ongoing
business, undisclosed liabilities, the failure to realize anticipated benefits
(such as synergies and cost savings), and issues related to product integration
and transition (such as development, distribution and customer support). The
Company expects that the consideration paid in future acquisitions, if any,
would be in the form of stock, rights to purchase stock, cash or a combination
thereof. Dilution to existing stockholders and earnings per share may result to
the extent that shares of stock or other rights to purchase stock are issued in
connection with any such future acquisitions. Some of the risks associated with
joint development agreements or technology licenses include development delays,
product bugs or errors, issues related to the integration or transition of the
new products, such as providing adequate customer support, effectively selling
and marketing the new product and coordinating development efforts.

        DEPENDENCE ON DISTRIBUTION CHANNELS. The Company distributes its
Platinum for DOS and Platinum for Windows products exclusively through
third-party distributors and Value Added Resellers ("VARs"), and distributes its
Platinum SQL software product through a direct sales force as well as through
VARs and distributors. The Company's distribution channel includes distributors,
VARs and Authorized Consultants, which consist primarily of professional firms.
Although no one of these distribution channel members is responsible for any
material amount of the Company's license fees, the Company's results of
operations could be adversely affected if significant numbers of its VARs or
Authorized Consultants were to cease distributing or recommending the Company's
products or were to choose to emphasize competing products. Generally, the
Company's agreements with its VARs and Authorized Consultants do not require
them to exclusively offer or recommend the Company's products and may be
terminated by either party with or without cause.

        In the fourth quarter of fiscal 1996, the Company reestablished a direct
sales force for its middle market client server financial software product,
Platinum SQL. There can be no assurance that the direct sales force will not
cause conflicts with the Company's VAR channel.


                                       12


<PAGE>   13

        The Company's Platinum SQL product was first introduced on a limited
basis to the network of VARs during the quarter ended December 31, 1994.
Platinum SQL, a client/server financial software application designed to run on
Microsoft Windows NT, Microsoft SQL server and Sybase SQL server, is a more
technically complex product than Platinum for Windows and Platinum-DOS and
requires additional skill and training to successfully implement. The Company
presently has over 70 authorized VARs who have completed training from which
approximately 30 VARs generate greater than 90% of the indirect sales of
Platinum SQL and is actively seeking additional skilled VARs to sell Platinum
SQL. Delays in training VARs or recruiting additional skilled VARs could
adversely impact the Company's ability to generate license revenues from its
Platinum SQL product line.

        DEPENDENCE ON PLATINUM SQL PRODUCT LINE. Platinum SQL, which is a
successor product to Platinum SQL Enterprise, which was first introduced in June
1992, and to Platinum SQL NT, which was first introduced in December 1994, is an
integrated financial and management information software product for use on
client/server computing systems. It is common for complex programs such as
Platinum SQL to contain undetected errors when first released or subsequently
enhanced, which are discovered only after the product has been used with many
different computer systems and in varying applications. The inability of the
Company to correct any serious errors, or any significant delay in correcting
any serious errors could have a material adverse effect on the Company's results
of operations. In addition, there can be no assurance that significant technical
problems will not be discovered, or if discovered, corrected in a timely manner.
Technical problems with the current release of the database platforms on which
Platinum SQL operate could impact sales of these Company products, and any
significant technical problems could have a material adverse effect on the
Company's results of operations.

        NEW PRODUCT INTRODUCTIONS. The Company's future success will depend upon
its ability to develop and successfully introduce new products, enhance its
current products on a timely basis and increase customer acceptance of its
existing products. The Company has three principal product lines, Platinum for
Windows (including Platinum for DOS), Platinum SQL (including financial
accounting, distribution and manufacturing applications) and Clientele. The
Company continues to provide maintenance and support services for its Platinum
SQL Enterprise product for existing customers. Platinum SQL was released in the
quarter ended December 31, 1994 and some of the core accounting modules of
Platinum for Windows were released during the quarters ended December 31, 1996,
June 30, 1996 and December 31, 1995. Version 4.2 of Platinum SQL, which will
include enhanced consolidation capabilities and new on-line planning wizards and
troubleshooting utilities as well as maintenance fixes, is scheduled for release
in the fourth fiscal quarter of 1998. See "Forward Looking Statements." Version
3.0 of Clientele, which will include sales force automation, is scheduled for
release in the third fiscal quarter of 1998. See "Forward Looking Statements."
In the past, the Company has occasionally experienced delays in the introduction
of new products and product enhancements. There can be no assurance that the
Company will be successful in developing and marketing these new products or
product enhancements on a timely basis or that the Company will not experience
significant delays in introducing new products in the future, which could have a
material adverse effect on the Company's results of operations. In addition,
there can be no assurance that new products or product enhancements developed by
the Company will achieve market acceptance.

        COMPETITION. The computer software industry is intensely competitive and
rapidly changing. A number of companies offer products similar to the Company's
products that target the same markets. Some of the Company's existing
competitors, as well as a number of new potential competitors, have larger
technical staffs, more established and larger marketing and sales organizations
and significantly greater financial resources than the Company. There can be no
assurance that competitors will not develop products that are superior to the
Company's products or that achieve greater market acceptance. The Company's
future success will depend significantly upon its ability to increase its share
of its target markets and to license additional products and product
enhancements to existing customers. There can be no assurance that the Company
will be able to compete successfully or that competition will not have a
material adverse effect on the Company's financial condition and results of
operations.

<PAGE>   14

        EXPOSURE TO RAPID TECHNOLOGICAL CHANGE. The market for the Company's
financial accounting and other line of business software products is
characterized by rapid technological advances, changes in end-user requirements,
frequent new product introductions and enhancements and evolving industry
standards. The introduction of products embodying new technologies and the
emergence of new industry standards could render the Company's existing products
and products under development obsolete and unmarketable. The Company's future
success will depend upon its ability to address the increasingly sophisticated
needs of its customers by enhancing its current products and by developing and
introducing on a timely basis new products that keep pace with technological
developments and emerging industry standards, respond to evolving end user
requirements and achieve market acceptance. Any failure by the Company to
anticipate or adequately respond to technological developments or end-user
requirements, or any significant delays in product development or introduction,
could result in a loss of competitiveness or reduced revenues. If the Company is
unable, for technological or any other reason, to develop, introduce and sell
its products in a timely manner, the Company's business, operating results and
financial condition would be materially adversely affected. From time to time,
the Company or its present or future competitors may announce new products,
capabilities or technologies that have the potential to replace or shorten the
life cycles of the Company's existing products. There can be no assurance that
announcements of currently planned or other new products will not cause
customers to delay or alter their purchasing decisions in anticipation of such
products, which could have a material adverse effect on the Company's business,
operating results and financial condition.

        DEPENDENCE ON KEY PERSONNEL. The Company's success depends on the
continued service of key management personnel, including L. George Klaus, Chief
Executive Officer, William Pieser, Senior Vice President, Marketing and Business
Development, and Ken Lally, Senior Vice President, Worldwide Field Operations.
None of the Company's key personnel is subject to an employment agreement for a
specified time duration with the Company. In addition, the competition to
attract, retain and motivate qualified technical, sales and operations personnel
is intense. The Company has at times experienced, and continues to experience,
difficulty in recruiting qualified personnel, particularly in software
development and customer support. There can be no assurance that the Company can
retain its key personnel or attract other qualified personnel in the future. The
failure to attract or retain such persons could have a material adverse effect
on the Company's business, operating results, cash flows and financial
condition.

        RISKS ASSOCIATED WITH INTERNATIONAL SALES. In fiscal 1995, 1996 and
1997, international sales represented approximately 31%, 32% and 30%,
respectively, of the Company's revenues, and the Company believes that its
future growth is dependent in part upon its ability to increase revenues in
international markets. The Company intends to attempt to continue to expand its
operations outside of the United States and enter additional international
markets, which will require significant management attention and financial
resources. There can be no assurance, however, that the Company will be able to
successfully maintain or expand its international sales. International sales are
subject to inherent risks, including changes in regulatory requirements, tariffs
and other barriers, fluctuating exchange rates, difficulties in staffing and
managing foreign sales and support operations and the possibility of greater
difficulty in accounts receivable collection. There can be no assurance that any
of these factors will not have a material adverse effect on the Company's future
international sales and, consequently, on the Company's business, operating
results, cash flows and financial condition. See "Management's Discussion and
Analysis of Financial Conditions and Results of Operations."

        DEPENDENCE ON CLIENT/SERVER ENVIRONMENT. The Company's development
tools, application products and consulting and education services are intended
to help organizations build, customize or deploy solutions that operate in a
client/server computing environment. The client/server market is relatively new,
and there can be no assurance that organizations will continue to adopt
client/server environments or that customers of the Company that have begun the
migration to a client/server environment will broadly implement this model of
computing. The Company's future financial performance will depend in large part
on continued growth in the market for client/server software applications and
related services, which in turn will depend in part on the growth in the number
of organizations implementing client/server computing environments and the
number of applications developed for use in those environments. There can be no
assurance that these markets will continue to grow or that the Company will be
able to respond effectively to the evolving requirements of these markets. If
the market for client/server application products and services does not grow in
the future, or grows more slowly than the Company anticipates, or if the Company
fails to respond effectively to evolving requirements of this market, the
Company's business, financial condition and results of operations would be
materially adversely affected.

        SHARES ELIGIBLE FOR FUTURE SALE. As of February 5, 1998, the Company had
22,889,613 shares of common stock outstanding. There are presently 2,435,000
shares of Series B Preferred Stock and 213,803 shares of Series C Preferred
Stock outstanding. Each share of Series B Preferred Stock is convertible into
one share of common stock, as adjusted for stock dividends, combinations or
splits at the option of the holder. Each share of Series C Preferred Stock is
convertible into ten shares of common stock, as adjusted for stock dividends,
combinations or splits at the option of the holder. As a result, the Series B
and Series C Preferred Stock are convertible into 2,435,000 and 2,138,030 shares
of common stock, respectively. The holders of the Series B and Series C
Preferred Stock have the right to cause the Company to register the sale of the
shares of common stock issuable upon conversion of the Series B and Series C
Preferred Stock. Also, the Company has approximately 4,700,000 shares subject to
stock options which are issuable to employees under employee option plans. As a
result, a substantial number of shares of common stock will be eligible for sale
in the public market at various times in the future. Sales of substantial
amounts of such shares could adversely affect the market price of the Company's
common stock.

        POSSIBLE VOLATILITY OF STOCK PRICES. The market prices for securities of
technology companies, including the Company, have been volatile. Quarter to
quarter variations in operating results, changes in earnings estimates by
analysts, announcements of technological innovations or new products by the
Company or its competitors, announcements of major contract awards and other
events or factors may have a significant impact on the market price of the
Company's Common Stock. In addition, the securities of many technology companies
have experienced extreme price and volume fluctuations, which have often been
unrelated to the companies' operating performance. These conditions may
adversely affect the market price of the Company's Common Stock.

        Because of these and other factors affecting the Company's operating
results, past financial performance should not be considered an indicator of
future performance, and investors should not use historical trends to anticipate
results or trends in future periods.
