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 generally accepted accounting principles for interim financial
information and with the instructions to Form 10-Q and Article 10 of Regulation
S-X. Accordingly, they do not include all of the information and footnotes
required by generally accepted accounting principles for complete financial
statements. 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 and six-month periods ended June 30,
1997 are not necessarily indicative of the results that may be expected for the
year ended December 31, 1997. The Company suggests that these interim condensed
consolidated financial statements be read in conjunction with the consolidated
financial statements and notes thereto for the year ended December 31, 1996,
included in the Company's Annual Report to Stockholders filed with the
Securities and Exchange Commission.


Note B - Net Income Per Share

Net income per common share is based on the weighted average number of common
shares and common share equivalents.

In February 1997, the Financial Accounting Standards Board issued Statement No.
128, "Earnings per Share," which is effective for the Company beginning with its
December 31, 1997 annual report. The Company will be required to change the
method currently used to compute earnings per share and to restate all prior
periods. Under the new requirements for calculating primary earnings per share,
the dilutive effect of stock options will be excluded. There is no change to
either primary or fully diluted net income per share for the quarters ended June
30, 1996 and June 30, 1997 using the new method.

                      Management's Discussion and Analysis
                of Financial Condition and Results of Operations


Results of Operations

Three and Six Months Ended June 30, 1997 Compared to 
Three and Six Months Ended June 30, 1996

Revenue

Total revenue for the three months ended June 30, 1997 (the "1997 Three Month
Period") increased 89.7% to $12.2 million from $6.4 million for the three months
ended June 30, 1996 (the "1996 Three Month Period"). Total revenue for the six
months ended June 30, 1997 (the "1997 Six Month Period") increased 88.5% to
$21.5 million from $11.4 million for the six months ended June 30, 1996 (the
"1996 Six Month Period"). These increases were primarily due to an increase in
software license revenue.

Software license revenue for the 1997 Three Month Period increased 131.9% to
$9.0 million from $3.9 million for the 1996 Three Month Period. Software license
revenue for the 1997 Six Month Period increased 141.8% to $15.5 million from
$6.4 million for the 1996 Six Month Period. The increase in software license
revenue was primarily attributable to software license acceptances by new
customers, software license agreement renewals, and extended software usage by
existing customers.

Services revenue for the 1997 Three Month Period increased 26.2% to $3.3 million
from $2.6 million for the 1996 Three Month Period. Services revenue for the 1997
Six Month Period increased 20.2% to $6.0 million from $5.0 million for the 1996
Six Month Period. The increase in services revenue was primarily attributable to
increased implementation services for new customers, additional consulting
services provided to existing customers, and to a lesser extent, increased
maintenance revenue from a larger installed product base.

Cost of Revenue

Cost of software license for the 1997 Three Month Period decreased 91.7% to
$0.01 million from $0.1 million for the 1996 Three Month Period, and decreased
as a percentage of total revenue from 1.8% for the 1996 Three Month Period to
0.1% for the 1997 Three Month Period. As a percentage of software license
revenue, cost of software license decreased from 3.1% for the 1996 Three Month
Period to 0.1% for the 1997 Three Month Period. As a percentage of software
license revenue, cost of software license decreased from 3.7% for the 1996 Six
Month Period to 0.1% for the 1997 Six Month Period. Software development costs
were fully amortized during 1996 and no software development costs were
capitalized during the 1997 Three or Six Month Period.

Cost of services for the 1997 Three Month Period increased 48.2% to $2.3 million
from $1.6 million for the 1996 Three Month Period. Cost of services for the 1997
Six Month Period increased 46.0% to $4.4 million from $3.0 million for the 1996
Six Month Period. Cost of services as a percentage of total revenue decreased
from 24.6% for the 1996 Three Month Period to 19.2% for the 1997 Three Month
Period. This decrease was due to the growth in the Company's total revenue. Cost
of services as a percentage of total revenue decreased from 26.3% for the 1996
Six Month Period to 20.3% for the 1997 Six Month Period. Cost of services as a
percentage of services revenue increased from 61.5% for the 1996 Three Month
Period to 72.2% for the 1997 Three Month Period. Cost of services as a
percentage of services revenue increased from 59.8% for the 1996 Six Month
Period to 72.7% for the 1997 Six Month Period. These increases were both
primarily due to the buildup of new staff, primarily in the Company's regional
offices, and use of the Company's service personnel to build templates which can
be reused in other customer applications.




Form 10-Q                                                          Page 8 of 12

Operating Expenses

Research and development expenses for the 1997 Three Month Period increased
57.2% to $3.0 million from $1.9 million for the 1996 Three Month Period.
Research and development expenses for the 1997 Six Month Period increased 54.0%
to $5.4 million from $3.5 million for the 1996 Six Month Period. The level of
increase in research and development expenses reflects the Company's strategy of
leveraging existing product functionality by shifting its historical investment
in research and development to a more sales-oriented focus. As a percentage of
total revenue, research and development expenses declined from 29.8% for the
1996 Three Month Period to 24.7% for the 1997 Three Month Period. As a
percentage of total revenue, research and development expenses declined from
30.9% for the 1996 Six Month Period to 25.3% for the 1997 Six Month Period. Both
of these declines were due to the growth in the Company's total revenue.

Selling and marketing expenses for the 1997 Three Month Period increased 218.4%
to $4.1 million from $1.3 million for the 1996 Three Month Period. As a
percentage of total revenue, selling and marketing expenses increased from 19.9%
for the 1996 Three Month Period to 33.4% for the 1997 Three Month Period.
Selling and marketing expenses for the 1997 Six Month Period increased 192.3% to
$6.6 million from $2.3 million for the 1996 Six Month Period. As a percentage of
total revenue, selling and marketing expenses increased from 19.8% for the 1996
Six Month Period to 30.7% for the 1997 Six Month Period. These increases were
primarily attributable to the hiring of additional direct sales and marketing
personnel, commission payments on new sales increased investment in marketing
support activities and materials, additional trade show activities, preparations
for the Company's User Meetings, and the opening of additional regional offices.

General and administrative expenses for the 1997 Three Month Period increased
49.2% to $0.6 million from $0.4 million for the 1996 Three Month Period. General
and administrative expenses for the 1997 Six Month Period increased 47.2% to
$1.2 million from $0.8 million for the 1996 Six Month Period. These increases
were due to increased investment in the infrastructure needed to support the
Company's accelerated growth. General and administrative expenses declined as a
percentage of total revenue from 6.2% for the 1996 Three Month Period to 4.9%
for the 1997 Three Month Period and from 6.9% for the 1996 Six Month Period to
5.4% for the 1997 Six Month Period due to the growth in the Company's total
revenue.

License Interest Income

License interest income which is the portion of all license fees due under
software license agreements which was not recognized upon product acceptance or
license renewal increased 11.3% from $0.38 million for the 1996 Three Month
Period to $0.42 million for the 1997 Three Month Period. License interest income
increased 6.6% from $0.75 million for the 1996 Six Month Period to $0.80 million
for the 1997 Six Month Period due to the increase in the Company's installed
customer base.

Provision for Income Taxes

The provisions for federal, state and foreign taxes were $0.6 million and $1.4
million for the 1996 Three Month Period and the 1997 Three Month Period,
respectively. The provisions for federal, state and foreign taxes were $0.9
million and $2.5 million for the 1996 Six Month Period and the 1997 Six Month
Period, respectively. The effective tax rate decreased from 39.0% for 1996 Three
and Six Month Periods to 38.0% for the 1997 Three and Six Month Periods. These
decreases were due to the reinstatement by the Internal Revenue Service of the
research and development tax credit in May 1996 and tax benefits to the Company
following employee stock option exercises.

Liquidity and Capital Resources

Since its inception, the Company had funded its operations primarily through
cash flow from operations and bank borrowings. In July 1996, the Company issued
and sold 2.7 million shares of Common Stock in connection with its initial
public offering. Proceeds to the Company from such offering were approximately
$30.1 million. In 



Form 10-Q                                                          Page 9 of 12

January 1997, the Company issued and sold 1.8 million shares of Common Stock in
connection with a second public offering. Proceeds to the Company from such
offering were approximately $52.4 million. At June 30, 1997, the Company had
cash and cash equivalents of approximately $72.5 million and working capital of
approximately $87.7 million. The Company's approach of charging license fees
payable in installments over the term of its licenses has historically deferred
the receipt of cash and, prior to its initial public offering, had limited the
availability of working capital.

Net cash used by operating activities for the 1997 Six Month period was $2.4
million, primarily due to an increase in accounts receivable, partially offset
by an increase in deferred revenue and accounts payable and accrued expenses.

Net cash used by investing activities was $1.6 million during the 1997 Six Month
Period due to the purchase of property and equipment consisting mainly of
computer hardware and software and furniture and fixtures to support the
Company's growing employee base.

Net cash provided by financing activities was $52.4 million during the 1997 Six
Month Period mainly due to the completion of the Company's second public
offering.

The Company's capital commitments consist primarily of operating leases for
office space and equipment. At June 30, 1997, the Company's commitments under
non-cancellable operating leases for office space with terms in excess of one
year totaled $0.7 million, $1.4 million and $0.6 million for 1997, 1998 and
1999, respectively. The Company's total payments under such leases was $0.7
million for the 1997 Six Month Period.

The Company's $5.0 million revolving credit line, which expired on June 30,
1997, was renewed with the same bank and has a maturity date of June 30, 1999.
At June 30, 1997, the Company had no borrowings under its revolving credit line.
The Company's credit agreement prohibits the payment of dividends, has
profitability requirements and requires maintenance of specified levels of
tangible net worth and certain financial ratios.

The Company recorded no bad debt expense in the 1997 Six Month Period.

The Company believes that the net proceeds from its two recent public offerings
together with cash generated by operations and availability under its bank
credit facility will be sufficient to fund the Company's operations for at least
the next year. However, there can be no assurance that additional capital beyond
the amounts currently forecasted by the Company will not be required or that any
such required additional capital 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, nor does the Company expect it to have a significant impact in the future
due to the fact that the Company's license and maintenance fees are typically
subject to annual increases based on recognized inflation indexes.
