Note A - Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of
Pegasystems Inc. (the "Company") presented herein have been prepared in
accordance with accounting principles generally accepted in the United States of
America and with the instructions to Form 10-Q and Article 10 of Regulation S-X.
In the opinion of management, all adjustments (consisting of normal recurring
accruals) considered necessary for a fair presentation have been included.
Operating results for the three-month period ended March 31, 2001 are not
necessarily indicative of the results that may be expected for the full year
ending December 31, 2001.  The Company suggests that these condensed
consolidated financial statements be read in conjunction with the consolidated
financial statements and notes thereto for the year ended December 31, 2000,
included in the Company's 2000 Annual Report on Form 10-K filed with the
Securities and Exchange Commission ("SEC").

Note B - Revenue Recognition

The Company's revenue is derived from two principal sources: software license
fees and services fees. Software license fees are generally payable on a monthly
basis under license agreements, which generally have a five-year term and may be
renewed for additional years at the customer's option. The present value of
future license payments is generally recognized as revenue upon customer
acceptance. A portion of the fee from each arrangement is deferred and
recognized as installment receivable interest income over the license term. In
the case of software license agreement renewals, license fee revenue is
recognized upon the commencement of the new license terms.

The Company's services revenue is comprised of fees for implementation,
consulting, maintenance, and training services. Software license customers are
offered the option to enter into an annual maintenance contract requiring the
customer to pay a monthly maintenance fee renewable on a year-to-year basis.
Prepaid maintenance fees are deferred based on their estimated fair value and
are recognized ratably over the term of the maintenance agreement. The Company's
software implementation agreements typically require the Company to provide a
specified level of implementation services for a specified fee, typically with
additional implementation services available at an hourly rate. Implementation
fees for time and material projects are recognized as incurred. Implementation
fees for fixed price projects are recognized once the fair value of services and
any other elements to be delivered under the arrangement can be determined.
Costs associated with fixed price contracts are expensed as incurred. Prior to
the point at which the fair value of the elements of a contract can be
determined, revenue recognition is limited to amounts equal to costs incurred
during the reporting period, resulting in no gross profit. Once the fair values
of the elements of a contract are apparent, profit associated with the services
elements will begin to be recognized. Training and consulting fees are generally
recognized as the services are provided.

Basic earnings (loss) per share is computed based on the weighted average number
of common shares outstanding during the period.  Diluted earnings (loss) per
share includes, to the extent inclusion of such shares would be dilutive to
earnings per share, the effect of outstanding options and warrants, computed
using the treasury stock method.  For the three-months ended March 31, 2001 and
2000, 6,259,051 and 5,137,389 potential shares, respectively, have been excluded
from the calculation, as such effect would be anti-dilutive.

Note E - Commitments and Contingencies

Company Litigation
------------------

Ernst & Young Case.  On June 9, 2000, the Company, Alan Trefler, the Company's
Chief Executive Officer, and Ira Vishner (a former chief financial officer of
the Company) filed a complaint against Ernst & Young LLP ("Ernst & Young") and
Alan B. Levine (a former partner of Ernst & Young) in Massachusetts state court
("the Complaint"). The Complaint alleged that the defendants committed
professional malpractice, breached contractual and fiduciary duties owed to the
Company, and issued false and misleading public statements, in


                                                                    Page 8 of 17


connection with advice that Ernst & Young rendered to the Company to record $5
million in revenue in its financial statements for the second fiscal quarter
ended June 30, 1997 pursuant to a series of contracts between the Company and
First Data Resources, Inc. (the "FDR Contracts"). The Complaint sought
compensatory damages, including contribution for losses and other costs incurred
in connection with certain class action securities litigation, now settled,
arising out of the Company's accounting for the FDR Contracts. On April 5, 2001,
the court dismissed the Complaint, finding that it was subject to the dispute
resolution procedures set forth in an engagement letter between the Company and
Ernst & Young. Pursuant to those dispute resolution procedures, on April 19,
2001, the Company and Messrs. Trefler and Vishner, through counsel, notified
Ernst & Young and Mr. Levine of their intention to submit the dispute that was
the subject of the court action to mediation. If mediation is unsuccessful, the
dispute resolution procedures provide that the dispute be submitted to
arbitration.

SEC Investigation.  In May 1999, the Boston office of the SEC issued a Formal
Order of Private Investigation of the Company and unidentified individuals,
currently or formerly associated with the Company, concerning past accounting
matters, financial reports, and other public disclosures and trading activity in
the Company's securities during 1997 and 1998. The Company continues to
cooperate fully with the investigation.

Note F - Restructuring

During the three months ended December 31, 2000, the Company recorded a one-time
restructuring charge of $1.0 million for the severance of 75 employees in
various locations and certain costs associated with leased facilities.
Approximately $0.2 million of additional depreciation expense was recorded due
to reduced economic life of the leased facilities to be closed or idled under
the restructuring plan. Restructuring activity associated with leased facilities
is expected to be completed by the third quarter of 2001.  As of December 31,
2000, $0.8 million of accrued severance remained unpaid.  As of March 31, 2001,
$0.1 million of accrued severance remained unpaid.

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

Historically, the timing of the Company's revenue has been unpredictable.  The
timing of license revenue recognition is related to the completion of
implementation services and acceptance of the licensed software by the customer,
the timing of which has proven difficult to predict accurately.  The Company is
more focused on closing larger but fewer license transactions than in the past.
This may increase the volatility of the Company's quarterly operating results.

Three Months Ended March 31, 2001 Compared to Three Months Ended March 31, 2000

Total revenue for the three months ended March 31, 2001 ("first quarter of
2001") increased 27% to $22.8 million from $18.0 million in the three months
ended March 31, 2000 ("first quarter of 2000").  The increase in total revenue
was due to an increase in software license revenue.

Software license revenue for the first quarter of 2001 increased 79% to $10.9
million from $6.1 million in the first quarter of 2000.  The increase was due
primarily to software license lease renewals.  An increase in perpetual license
revenues to $1.5 million was offset by reduced revenues from new and add-on
leases.  Of the total increase in revenue, $0.6 million was due to improved
accounting estimates relating to the revenue attributable to the inflation
adjustment provisions contained in the Company's long-term software license
agreements.  These improved accounting estimates will continue to benefit the
remaining quarters of 2001.  A significant portion of the Company's software
license revenue is from existing customers.

Services revenue from the first quarter of 2001 at $11.9 million was consistent
with the first quarter of 2000.


                                                                   Page 9 of 17


Deferred revenue balances increased to $6.7 million as of March 31, 2001 from
$5.1 million as of December 31, 2000, due primarily to annual maintenance
billings in the first quarter of 2001 that are taken to revenue ratably during
the year.

Cost of Revenue

Cost of software license revenue for the first quarter of 2001 increased 11% to
$0.65 million from $0.59 million in the first quarter of 2000.  Cost of software
license includes the amortization associated with a stock purchase warrant
issued by the Company in June 1997, and the Company's acquisition of software
for resale.  The increase was due to additional software acquired by the
Company, which is being amortized over three years.  Cost of software license as
a percentage of license revenue decreased to 6% from 10% in the first quarter of
2000 due to the increase in license revenue.

Cost of services consists primarily of the costs of providing implementation,
consulting, maintenance, and training services.  Cost of services for the first
quarter of 2001 increased 10% to $9.5 million from $8.6 million for the first
quarter of 2000.  Cost of services as a percentage of services revenue increased
to 79% for the first quarter of 2001 from 72% for the first quarter of 2000.
The increases were due to higher incentive compensation and benefits accruals
and third party contracted consultants billed to customers, partially offset by
the impact of the reduction in headcount implemented in the first quarter of
2001.  Incentive compensation increased due to a combination of enhanced
incentive opportunities and better performance versus goals.

Operating Expenses

Research and development expenses for the first quarter of 2001 increased 27% to
$5.0 million from $3.9 million for the first quarter of 2000. The increase was
due to higher incentive compensation and benefits accruals, contracted
resources, and the redeployment of internal resources as part of the
restructuring.  As a percentage of total revenue, research and development
expenses were 22% for the first quarter of 2001 and the first quarter of 2000.

Selling and marketing expenses for the first quarter of 2001 decreased to $4.9
million from $5.0 million for the first quarter of 2000.  As a percentage of
total revenue, selling and marketing expenses decreased to 22% for the first
quarter of 2001 from 28% for the first quarter of 2000.  The decreases were due
to reduced discretionary spending such as travel and infrastructure costs,
partially offset by higher incentive compensation accruals.

General and administrative expenses for the first quarter of 2001 increased 15%
to $3.0 million from $2.6 million for the first quarter of 2000. The increase
was due to higher incentive compensation and benefits accruals, corporate
insurance costs, and miscellaneous tax accruals.  As a percentage of total
revenue, general and administrative expenses decreased to 13% for the first
quarter of 2001 from 14% for the first quarter of 2000.

Installment Receivable Interest Income

Installment receivable interest income, which consists of the portion of all
license fees under long-term software license lease agreements that is
attributable to the time value of money, increased to $1.5 million in the first
quarter of 2001 from $0.9 million in the first quarter of 2000.  This increase
was due to improved accounting estimates regarding the amount of interest income
earned and higher average discount rates.  A portion of the fee from each
license lease arrangement is initially deferred and recognized as installment
receivable interest income over the rest of the license term.  For purposes of
the present value calculations, the discount rate used has varied between 6.25%
and 8.00% for the past few years.

Other Interest Income, net

Other interest income, net, decreased to $0.2 million in the first quarter of
2001 from $0.4 million in the first quarter of 2000, due to lower average
balances of cash and cash equivalents.



                                                                   Page 10 of 17


Other Income (Expense), net

Other income (expense), net, which consists primarily of currency exchange gains
or losses and reseller development funds received from third-party vendors of
computer hardware products, was a $0.1 million loss for the first quarter of
2001, compared to a small gain in the first quarter of 2000.  This decrease was
due primarily to larger currency exchange losses, partially offset by increased
reseller development funds received.

Provision for Income Taxes

The tax provision of $0.3 million for the first quarter of 2001 related to
foreign subsidiary income tax, compared to a very small provision in the first
quarter of 2000.

Liquidity and Capital Resources

Since its inception, the Company has funded its operations primarily through
cash flow from operations, bank borrowings, and proceeds from the Company's
public stock offerings.  At March 31, 2001, the Company had cash and cash
equivalents of $20.1 million and working capital of $47.1 million.

Net cash provided by operations for the first quarter of 2001 was $3.1 million
compared with a small amount used in operations in the first quarter of 2000.
The increase was due primarily to improved collections of annual billings,
partially offset by increased operating expenses.  Billings during the first
quarter include annual license and maintenance amounts for some customers,
typically resulting in more cash collections during the first quarter than in
following quarters.

Net cash used in investing activities was $0.1 million for the first quarter of
2001, compared to $0.3 million in the first quarter of 2000.  The change was due
to a reduction in expenditures for equipment and improvements and a reduction in
other long-term assets.

Financing activities used $27 thousand of cash during the first quarter of 2001,
compared with providing $0.9 million during the first quarter of 2000.  This
change was mostly due to fewer exercises of stock options and a change made last
year in the timing of the sale of stock under the Company's Employee Stock
Purchase Plan ("ESPP").  The ESPP sales were during the first and fourth
quarters of 2000, and will be during the second and fourth quarters of 2001.

The Company believes that current cash and cash equivalents will be sufficient
to fund the Company's operations for the near term.  There can be no assurance,
however, that changes in the Company's plans or other events affecting the
Company's operations will not result in materially accelerated or unexpected
expenditures.  In addition, there can be no assurance that additional capital,
if needed, will be available on reasonable terms, if at all, at such time as
required by the Company.

Inflation

Inflation has not had a significant impact on the Company's operating results to
date, and the Company does not expect it to have a significant impact in the
future.  The Company's license and maintenance fees are typically subject to
annual increases based on recognized inflation indexes.


                                                                   Page 11 of 17


Forward-Looking Statements

Certain statements contained in this Form 10-Q/A may be construed as "forward-
looking statements" as defined in the Private Securities Litigation Reform Act
of 1995.  These statements involve various risks and uncertainties which could
cause the Company's actual results to differ from those expressed in such
forward-looking statements.  These risks and uncertainties include the effect of
losses from prior periods, liquidity issues, regulatory proceedings, seasonal
variation of the Company's operations and fluctuations in the Company's
quarterly results, rapid technological change involving the Company's products
and those of competitors, delays in product development and implementation, the
technological compatibility of the Company's products with its customers'
systems, the Company's dependence on customers in the financial services market,
intense competition in the markets for the Company's products, risk of non-
renewal by current customers, and other risks and uncertainties.  Further
information regarding those factors which could cause the Company's actual
results to differ materially from any forward-looking statements contained
herein is provided below.

The Company is being investigated by the Securities and Exchange Commission.  In
May of 1999, the Boston office of the SEC issued a Formal Order of Private
Investigation of the Company and certain individuals, currently or formerly
associated with the Company, concerning past accounting matters, financial
reports and other public disclosures and trading activity in the Company's
securities during 1997 and 1998. Such investigation may result in the SEC
imposing fines on the Company or taking other measures that may have a material
adverse impact on the Company's financial position or results of operations. In
addition, regardless of the outcome of the investigation, it is likely that the
Company will incur substantial defense costs and that such investigation will
cause a diversion of management time and attention. Finally, the negative
publicity resulting from the investigation has made and may continue to make it
more difficult for the Company to close sales, which in turn could have a
material adverse impact on the Company's financial position or results of
operations.

The Company had material weaknesses in its internal control environment.  The
Company's independent public accountants identified material weaknesses in the
Company's internal control environment in connection with their audits of the
Company's 1997, 1998 and 1999 financial statements. This has had and may
continue to have a material adverse impact on the Company's reputation, which in
turn could have a material adverse impact on the Company's financial position or
results of operations. The Company has added resources to its finance function
and is working diligently with the suggestions of the auditors to improve
internal control. In connection with the audit of the Company's 2000 financial
statements the independent auditors have indicated that they will not issue a
material weakness letter.

Mr. O'Halloran, the Company's Chief Financial Officer, has indicated his
intention to retire during the second quarter of 2001.

The Company's stock price has been volatile.  Quarterly results have fluctuated
and are likely to continue to fluctuate significantly. The market price of the
Company's common stock has been and may continue to be highly volatile. Factors
that are difficult to predict, such as quarterly revenues and operating results,
statements and ratings by financial analysts, overall market performance and the
outcome of litigation, will have a significant effect on the price for shares of
the Company's common stock. Revenues and operating results have varied
considerably in the past from period to period and are likely to vary
considerably in the future. The Company plans product development and other
expenses based on anticipated future revenue. If revenue falls below
expectations, financial performance is likely to be adversely affected because
only small portions of expenses vary with revenue. As a result, period-to-period
comparisons of operating results are not necessarily meaningful and should not
be relied upon to predict future performance.

The timing of license revenues is related to the completion of implementation
services and product acceptance by the customer, the timing of which has been
difficult to predict accurately.  There can be no


                                                                   Page 12 of 17

assurance that the Company will be profitable on an annual or quarterly basis or
that earnings or revenues will meet analysts' expectations. Fluctuations may be
particularly pronounced because a significant portion of revenues in any quarter
is attributable to product acceptance or license renewal by a relatively small
number of customers. Fluctuations also reflect a policy of recognizing revenue
upon product acceptance or license renewal in an amount equal to the present
value of the total committed payments due during the term. Customers generally
do not accept products until the end of a lengthy sales cycle and an
implementation period, typically ranging from one to six months but in some
cases significantly longer. In addition, the Company is more focused on closing
larger but fewer license transactions than in the past. This may increase the
volatility in the Company's quarterly operating results. Risks over which the
Company has little or no control, including customers' budgets, staffing
allocation, and internal authorization reviews, can significantly affect the
sales and acceptance cycles. Changes dictated by customers may delay product
implementation and revenue recognition.

THE COMPANY WILL NEED TO DEVELOP NEW PRODUCTS, EVOLVE EXISTING ONES, AND ADAPT
TO TECHNOLOGY CHANGE.  Technical developments, customer requirements,
programming languages and industry standards change frequently in the Company's
markets. As a result, success in current markets and new markets will depend
upon the Company's ability to enhance current products, to develop and introduce
new products that meet customer needs, keep pace with technology changes,
respond to competitive products, and achieve market acceptance. Product
development requires substantial investments for research, refinement and
testing. There can be no assurance that the Company will have sufficient
resources to make necessary product development investments. Pegasystems may
experience difficulties that will delay or prevent the successful development,
introduction or implementation of new or enhanced products. Inability to
introduce or implement new or enhanced products in a timely manner would
adversely affect future financial performance. The Company's products are
complex and may contain errors. Errors in products will require the Company to
ship corrected products to customers. Errors in products could cause the loss of
or delay in market acceptance or sales and revenue, the diversion of development
resources, injury to the Company's reputation, or increased service and warranty
costs which would have an adverse effect on financial performance.

THE COMPANY HAS HISTORICALLY SOLD TO THE FINANCIAL SERVICES MARKET.  This market
is consolidating rapidly, and faces uncertainty due to many other factors. The
Company has historically derived a significant portion of its revenue from
customers in the financial services market, and its future growth depends, in
part, upon increased sales to this market. Competitive pressures, industry
consolidation, decreasing operating margins within this industry, currency
fluctuations, geographic expansion and deregulation affect the financial
condition of the Company's customers and their willingness to pay. In addition,
customers' purchasing patterns are somewhat discretionary. As a result, some or
all of the factors listed above may adversely affect the demand by customers.
The financial services market is undergoing intense domestic and international
consolidation. In recent years, several customers have been merged or
consolidated. Future mergers or consolidations may cause a decline in revenues
and adversely affect the Company's future financial performance.

IF EXISTING CUSTOMERS DO NOT RENEW THEIR LICENSES, THE COMPANY'S FINANCIAL
RESULTS MAY SUFFER.  A significant portion of total revenue has been
attributable to license renewals. While historically a substantial majority of
customers have renewed their licenses, there can be no assurance that a
substantial majority of customers will continue to renew expiring licenses. A
decrease in license renewals absent offsetting revenue from other sources would
have a material adverse effect on future financial performance. In addition,
possible transition to a perpetual or prepaid extended term license may have a
material adverse impact on the amount of license renewal revenues in future
periods.

THE COMPANY DEPENDS ON CERTAIN KEY PERSONNEL, AND MUST BE ABLE TO ATTRACT AND
RETAIN QUALIFIED PERSONNEL IN THE FUTURE.  The business is dependent on a number
of key, highly skilled technical, managerial, consulting, sales, and marketing
personnel, including Mr. Trefler, the Company's Chief Executive Officer. The
loss of key personnel could adversely affect financial performance. The Company
does not have any key-man



                                                                   Page 13 of 17


life insurance on any officers or employees and does not plan to put any in
place. The Company's success will depend in large part on its ability to hire
and retain qualified personnel. The number of potential employees who have the
extensive knowledge of computer hardware and operating systems needed to
develop, sell and maintain its products is limited, and competition for their
services is intense, and there can be no assurance that the Company will be able
to attract and retain such personnel. If the Company is unable to do so, the
Company's business, operating results, and financial condition could be
materially adversely affected.

The market for the Company's offerings is increasingly and intensely
competitive, rapidly changing, and highly fragmented.  The market for customer
relationship management software and related implementation, consulting and
training services is intensely competitive and highly fragmented. The Company
currently encounters significant competition from internal information systems
departments of potential or existing customers that develop custom software. It
also competes with companies that target the customer interaction and workflow
markets and professional services organizations that develop custom software in
conjunction with rendering consulting services. Competition for market share and
pressure to reduce prices and make sales concessions are likely to increase.
Many competitors have far greater resources and may be able to respond more
quickly and efficiently to new or emerging technologies, programming languages
or standards or to changes in customer requirements or preferences. Competitors
may also be able to devote greater managerial and financial resources to
develop, promote and distribute products and provide related consulting and
training services. There can be no assurance that the Company will be able to
compete successfully against current or future competitors or that the
competitive pressures faced by the Company will not materially adversely affect
its business, operating results, and financial condition.

The Company relies on certain third-party relationships.  The Company has a
number of relationships with third parties that are significant to sales,
marketing and support activities and product development efforts. The Company
relies on relational database management system applications and development
tool vendors, software and hardware vendors, and consultants to provide
marketing and sales opportunities for the direct sales force and to strengthen
the Company's products through the use of industry-standard tools and utilities.
The Company also has relationships with third parties that distribute its
products. In particular, the Company relies on its relationship with First Data
Corporation for the distribution of products to the credit card market, with
PFPC Inc. for distribution of products to the mutual fund market and on Carreker
Inc. for the distribution of its products to the banking industry. There can be
no assurance that these companies, most of which have significantly greater
financial and marketing resources, will not develop or market products that
compete with those of the Company in the future or will not otherwise end their
relationships with or support of the Company.

The Company may face product liability and warranty claims. The Company's
license agreements typically contain provisions intended to limit the nature and
extent of the Company's risk of product liability and warranty claims. There is
a risk that a court might interpret these terms in a limited way or could hold
part or all of these terms to be unenforceable. Also, there is a risk that these
contract terms might not bind a party other than the direct customer.
Furthermore, some of the Company's licenses with its customers are governed by
non-U.S. law, and there is a risk that foreign law might give the Company less
or different protection. Although the Company has not experienced any material
product liability claims to date, a product liability suit or action claiming a
breach of warranty, whether or not meritorious, could result in substantial
costs and a diversion of management's attention and the Company's resources.

The Euro's adoption imposes product and market risks.  A new currency, the
"Euro", was introduced in certain Economic and Monetary Union ("EMU") countries
in early 1999. It is expected that by 2002, all participating EMU countries will
use the Euro as their single currency. As a result, software used by many
companies headquartered or maintaining a subsidiary in a participating EMU
country is expected to be Euro-enabled. All companies headquartered or
maintaining a subsidiary in an EMU country will need to be Euro-enabled. These
changes will change budgetary, accounting and fiscal systems in companies and
public administration, and require the simultaneous handling of parallel
currencies and conversion of legacy data.


                                                                   Page 14 of 17


These requirements may curb market demand for the Company's products because the
budgets and priorities of its customers and prospective customers may change.
The Company is monitoring the rules and regulations as they become known in
order to make any changes to its software products that the Company deems
necessary to comply with such rules and regulations. Although the Company
believes that its most recent products address these requirements, there can be
no assurance that the rules and regulations will not change and that the
Company's software will contain all of the necessary changes or meet all Euro
requirements. Any inability to comply with the Euro requirements could have an
adverse effect on the Company's business, operating results and financial
condition.

The Company faces risks from operations and customers based outside of the U.S.
Sales to customers headquartered outside of the United States represented
approximately 26%, 21% and 23% of the Company's total revenue in 2000, 1999 and
1998, respectively. The Company, in part through its wholly owned subsidiaries
based in the United Kingdom, Singapore, and Australia, markets products and
renders consulting and training services to customers based in Canada, the
United Kingdom, France, Germany, the Netherlands, Switzerland, Ireland, Mexico,
Sweden, Australia, Austria, Hong Kong, and Singapore. The Company has
established offices in continental Europe and in Australia. The Company believes
that its continued growth will necessitate expanded international operations
requiring a diversion of managerial attention and financial resources. The
Company anticipates hiring additional personnel to accommodate international
growth, and the Company may also enter into agreements with local distributors,
representatives, or resellers. If the Company is unable to do one or more of
these things in a timely manner, the Company's growth, if any, in its foreign
operations will be restricted, and the Company's business, operating results,
and financial condition could be materially and adversely affected.

In addition, there can be no assurance that the Company will be able to maintain
or increase international market demand for its products. Most of the Company's
international sales are denominated in U.S. dollars. Accordingly, any
appreciation of the value of the U.S. dollar relative to the currencies of those
countries in which the Company distributes its products may place the Company at
a competitive disadvantage by effectively making its products more expensive as
compared to those of its competitors. Additional risks inherent in the Company's
international business activities generally include unexpected changes in
regulatory requirements, increased tariffs and other trade barriers, the costs
of localizing products for local markets and complying with local business
customs, longer accounts receivable patterns and difficulties in collecting
foreign accounts receivable, difficulties in enforcing contractual and
intellectual property rights, heightened risks of political and economic
instability, the possibility of nationalization or expropriation of industries
or properties, difficulties in managing international operations, potentially
adverse tax consequences (including restrictions on repatriating earnings and
the threat of "double taxation"), enhanced accounting and internal control
expenses, and the burden of complying with a wide variety of foreign laws. There
can be no assurance that one or more of these factors will not have a material
adverse effect on the Company's foreign operations, and, consequentially, the
Company's business, operating results, and financial condition.

The Company faces risks related to intellectual property claims or appropriation
of its intellectual property rights.  The Company relies primarily on a
combination of copyright, trademark and trade secrets laws, as well as
confidentiality agreements to protect its proprietary rights. In October 1998,
the Company was granted a patent by the United States Patent and Trademark
Office relating to the architecture of the Company's systems. There can be no
assurance that such patent will not be invalidated or circumvented or that
rights granted thereunder or the description contained therein will provide
competitive advantages to the Company's competitors or others. Moreover, despite
the Company's efforts to protect its proprietary rights, unauthorized parties
may attempt to copy aspects of the Company's products or to obtain the use of
information that the Company regards as proprietary. In addition, the laws of
some foreign countries do not protect the Company's proprietary rights to as
great an extent as do the laws of the United States. There can be no assurance
that the Company's means of protecting its proprietary rights will be adequate
or that the Company's competitors will not independently develop similar
technology.


                                                                   Page 15 of 17


The Company is not aware that any of its products infringe the proprietary
rights of third parties. There can be no assurance, however, that third parties
will not claim infringement by the Company with respect to current or future
products. The Company expects that software product developers will increasingly
be subject to infringement claims as the number of products and competitors in
the Company's industry segment grows and the functionality of products in
different industry segments overlaps. Any such claims, with or without merit,
could be time-consuming, result in costly litigation, cause product shipment
delays, or require the Company to enter into royalty or licensing agreements.
Such royalty or licensing agreements, if required, may not be available on terms
acceptable to the Company or at all, which could have a material adverse effect
upon the Company's business, operating results, and financial condition.


                                                                   Page 16 of 17

about Market Risk," in the Company's Annual Report on Form 10-K for the year

Part II - Other Information:

Item 1.  Legal Proceedings

Ernst & Young Case.  On June 9, 2000, the Company, Alan Trefler, the Company's
Chief Executive Officer, and Ira Vishner (a former chief financial officer of
the Company) filed a complaint against Ernst & Young LLP ("Ernst & Young") and
Alan B. Levine (a former partner of Ernst & Young) in Massachusetts state court
("the Complaint"). The Complaint alleged that the defendants committed
professional malpractice, breached contractual and fiduciary duties owed to the
Company, and issued false and misleading public statements, in connection with
advice that Ernst & Young rendered to the Company to record $5 million in
revenue in its financial statements for the second fiscal quarter ended June 30,
1997 pursuant to a series of contracts between the Company and First Data
Resources, Inc. (the "FDR Contracts"). The Complaint sought compensatory
damages, including contribution for losses and other costs incurred in
connection with certain class action securities litigation, now settled, arising
out of the Company's accounting for the FDR Contracts.  On April 5, 2001, the
court dismissed the Complaint, finding that it was subject to the dispute
resolution procedures set forth in an engagement letter between the Company and
Ernst & Young.  Pursuant to those dispute resolution procedures, on April 19,
2001, the Company and Messrs. Trefler and Vishner, through counsel, notified
Ernst & Young and Mr. Levine of their intention to submit the dispute that was
the subject of the court action to mediation.  If mediation is unsuccessful, the
dispute resolution procedures provide that the dispute be submitted to
arbitration.

SEC Investigation.  In May 1999, the Boston office of the SEC issued a Formal
Order of Private Investigation of the Company and unidentified individuals,
currently or formerly associated with the Company, concerning past accounting
matters, financial reports, and other public disclosures and trading activity in
the Company's securities during 1997 and 1998. The Company continues to
cooperate fully with the investigation.
