                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)

1.   BASIS OF PRESENTATION.

     The financial statements included herein have been prepared by the Company,
without audit, pursuant to the rules and regulations of the Securities and
Exchange Commission. Certain information and footnote disclosures normally
included in financial statements prepared in accordance with generally accepted
accounting principles have been condensed or omitted pursuant to such rules and
regulations. The Company believes that the disclosures are adequate to make the
information presented not misleading. However, it is suggested that these
financial statements be read in conjunction with the Company's audited financial
statements for the year ended December 31, 1997, included in its 1997 Annual
Report on Form 10-K/A.

     This financial information reflects, in the opinion of management, all
adjustments of a normal recurring nature necessary to present fairly the results
for the interim periods.  Results of interim periods may not be indicative of
results for the full year.

2.  RESTATEMENT RELATED TO ACQUIRED IN-PROCESS RESEARCH AND DEVELOPMENT

     The accompanying consolidated financial statements as of and for three- and
six-month periods ended June 30, 1998 have been restated to reflect a change in
the original accounting for the amount and allocation of the purchase price
related to the Company's acquisition of SQLBench in December 1997 as described
further in the Company's 1997 Annual Report on Form 10-K/A filed with the
Securities and Exchange Commission on March 27, 2000.

     Under the revised accounting, the value ascribed to the acquired IPR&D was
reduced from $9.1 million to $0.1 million, the value assigned to acquire
completed technology was increased from $1.0 million to $3.0 million, and
goodwill of $7.5 million was recorded.  The principal effects of this
restatement on previously reported consolidated financial statements as of June
30, 1998 and for three- and six-month periods ended June 30, 1998 are set forth
below (in thousands, except per share data):

     Options to purchase 174,000 and 664,000 shares of common stock outstanding
at June 30, 1998 and 1997, respectively, were excluded from the calculation of
diluted earnings per share because the exercise prices of those options exceeded
the average market price of common stock for the three month periods ended June
30, 1998 and 1997, respectively. Options to purchase 629,000 shares of common
stock outstanding at June 30, 1997 were excluded from the calculation of
diluted earnings per share because the exercise prices of those options exceeded
the average market price of common stock for the six-month period ended June 30,
1997. Options to purchase 1,784,000 shares of common stock outstanding at June
30, 1998 were excluded from the calculation of diluted earnings per share for
the six-month period ended June 30, 1998 because their inclusion would be anti-
dilutive.

4.   In March 1998, the Company entered into an agreement with a vendor whereby
the vendor licensed specific software to the Company for purposes of marketing
and distribution.  Under the terms of the agreement, the Company paid a
nonrefundable non-recurring engineering and initial license fee ("NRE") of
$480,000 during the second quarter of 1998 and $300,000 of the guaranteed
$500,000 royalties, the remainder of which will be paid by September 30, 1998.
The NRE fee is being amortized into cost of software revenue over two years,
beginning in the second quarter of 1998, and the royalty expense will be
recognized as cost of software revenue based upon sales of the related product.
As of June 30, 1998, there were minimal sales of the related product.

5.   In April 1998, the Company entered into a nine year lease commitment for
40,500 to 67,500 square feet, effective August 1, 1998, which expires in October
2007.  The Company has the right to terminate the lease on September 30, 2004
for a fee of approximately $2.2 million.

6.   The Company recorded provisions for state income taxes of $30,000 and
$8,000 for the second quarter of 1998 and 1997, respectively, and a total of
$56,000 for the six month periods ended June 30, 1998 and 1997, but no
provisions for federal income taxes due to utilization of net operating loss
carryforwards.

7.   Effective January 1, 1998, the Company adopted Statement of Financial
Accounting Standards No. 130 ("SFAS 130"), "Reporting Comprehensive Income".
SFAS 130 requires the reporting of comprehensive income in addition to net
income from operations. Comprehensive income is a more inclusive reporting
methodology that includes disclosure of certain financial information that
historically has not been recognized in the calculation of net income. The
adoption of SFAS 130 had no impact on the Company's net income or stockholders'
equity. Total comprehensive income (loss), net of taxes, for the three and six
months ended June 30, 1998, was $70,000 and $(46,000), respectively, which
consists of net income (loss) and the net changes in foreign currency
translation adjustment. For the three and six months ended June 30, 1997,
comprehensive income equaled net income.

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

RESTATEMENT RELATED TO ACQUIRED IN-PROCESS RESEARCH AND DEVELOPMENT

     The accompanying consolidated financial statements as of and for the three-
and six-month periods ended June 30, 1998 have been restated to reflect a change
in the original accounting for the amount and allocation of the purchase price
related to the Company's acquisition of SQLBench in December 1997 as described
further in the Company's 1997 Annual Report on Form 10-K/A filed with the
Securities and Exchange Commission on March 27, 2000.  Under the revised
accounting recorded as of December 31, 1997, the value ascribed to the acquired
IPR&D was reduced from $9.1 million to $0.1 million, the value assigned to
acquired completed technology was increased from $1.0 million to $3.0 million,
and goodwill of $7.5 million was recorded.

     The principal effects of this restatement on previously reported results of
operations for the three-month period ended June 30, 1998 were an increase in
total operating expenses from $6.7 million to $7.1 million for the impact of
amortization of acquired intangible assets, a corresponding decrease in net
income from $618,000 to $78,000, and a decrease in net income per share from
$0.07 to $0.01.  The principal effects of this restatement on previously
reported results of operations for the six-month period ended June 30, 1998 were
an increase in total operating expenses from $13.0 million to $13.7 million for
the impact of amortization of acquired intangible assets, a corresponding
decrease in net income from $1.0 million to a net loss of $49,000, and a
decrease in net income per share from $0.12 to a net loss per share of
$0.01.

REVENUE

     Revenue from Software.  Software revenue increased 56% to $6.0 million
during the second quarter of 1998 from $3.9 million in the second quarter of
1997.  For the six month period ended June 30, 1998, software revenue increased
49% to $11.7 million from $7.9 million for the first six months of 1997.  The
increases in software revenue are primarily the result of increased unit
shipments due to an increase in the demand for automated testing products; the
introduction of new and upgraded products; increased market acceptance of the
families of products including Web application testing and load testing products
introduced in 1997; and expansion of sales and marketing activities.  The
absolute dollar increase in software revenue came largely through the direct
domestic channel.  International revenue accounted for 13% and 11% of total
software revenue in the second quarter of 1998 and 1997, respectively.  For the
six months ended June 30, 1998 and 1997 respectively, international revenue
accounted for 13% and 10% of total software revenue.

     In addition, the mix of software revenue changed during the three and six
months ended June 30, 1998 from the three and six months ended June 30, 1997.
SilkTest and SilkPerformer, which target the e-commerce testing markets, were
not available until May 1997 and September 1997, respectively.  SilkTest and
SilkPerformer represented 52% and 47% of total software revenue in the three and
six months ended June 30, 1998, respectively.  SilkTest represented 18% and 9%
of total software revenue in the three and six months ended June 30, 1997,
respectively.  QA Performer and SilkPerformer, which target the load testing
markets, in total represented 19% and 18% of total software revenue in the three
and six months ended June 30, 1998, respectively.  QA Performer represented 2%
of total software revenue in the three and six months ended June 30, 1997,
respectively.

     Revenue from Services. Service revenue increased 87% to $2.8 million during
the second quarter of 1998 from $1.5 million in the second quarter of 1997
driven by the increase in maintenance revenue and training and consulting
revenue related to the increase in software licenses sold. For the three month
period ended June 30, 1998, training and consulting revenue increased 200% and
maintenance revenue increased 35% over the comparable period in 1997. For the
six month period ended June 30, 1998, service revenue increased 58% to $4.6
million from $2.9 million for the corresponding prior year period. For the six
month period ended June 30, 1998, training and consulting revenue increased
101%, while maintenance revenue increased 36% over the comparable period in
1997. These increases were driven largely by an increase in software licenses
sold. The increase in training and consulting revenue is also due to the
introduction of the LiveQuality scenario testing solutions, which consist of a
combination of product and consulting services, in the second quarter of 1998.


                                       7

COST OF REVENUE

     Cost of Software.  Cost of software increased 283% to $720,000 during the
second quarter of 1998 from $188,000 in the second quarter of 1997.  For the six
month period ended June 30, 1998, cost of software increased 237% to $1.3
million from $387,000 for the six month period ended June 30, 1997. As a percent
of software revenue, costs in the current quarter increased to 12% from 5% in
the corresponding prior year period. For the six month period ended June 30,
1998, cost of software as a percent of software revenue increased to 11% from 5%
in the corresponding prior year period. These increases are due to the
amortization of intangible assets primarily related to the SQLBench acquisition,
the internationalization of QA Partner, and the NRE fee noted below. These
increases are also attributable to the cost of upgrading the installed base with
new versions of various products as well as royalties payable to third
parties.

     In March 1998, the Company entered into an agreement with a vendor whereby
the vendor licensed specific software to the Company for purposes of marketing
and distribution.  Under the terms of the agreement, the Company paid a
nonrefundable non-recurring engineering and initial license fee ("NRE") of
$480,000 during the second quarter of 1998 and $300,000 of the guaranteed
$500,000 royalties, the remainder of which will be paid by September 30, 1998.
The NRE fee is being amortized into cost of software revenue over two years,
beginning in the second quarter of 1998, and the royalty expense will be
recognized as cost of software revenue based upon sales of the related product.
As of June 30, 1998, there were minimal sales of the related product. The
amortization and the guaranteed royalty payments may cause the cost of software
to increase as a percentage of revenue.

     Cost of Services.  Cost of services increased 91% to $1.3 million during
the second quarter of 1998 from $677,000 in the second quarter of 1997.  For the
six month period ended June 30, 1998, cost of services increased 68% to $2.0
million from $1.2 million for the six months ended June 30, 1997.  For the three
months ended June 30, 1998 and 1997, cost of services as a percent of services
revenue was 46%.  For the six months ended June 30, 1998, cost of services as a
percent of services revenue increased to 45% from 42% in the corresponding prior
year period.  The increases, in absolute dollars, in the current quarter over
the prior year and for the current six months over the comparable six month
period in the prior year are largely due to the fact that the Company began to
use third party consultants to assist in LiveQuality solution implementations in
the second quarter of 1998.  The Company expects to continue using third party
consultants in the future.  The increases are also due to the increase in the
number of employees in both the training and consulting and technical support
groups.

OPERATING EXPENSES

     Sales and Marketing. Sales and marketing expenses increased 47% to $4.2
million during the second quarter of 1998 from $2.8 million in the second
quarter of 1997.  For the six months ended June 30, 1998, sales and marketing
expenses increased 49% to $8.0 million from $5.4 million for the first six
months of 1997.  Sales and marketing expenses were 47% and 53% of total revenue
in the second quarter of 1998 and 1997, respectively, and 49% and 50% of total

                                       8
<PAGE>

revenue during the six month periods ended June 30, 1998 and 1997, respectively.
The absolute dollar increases in the current quarter over the prior year and for
the current six months over the comparable six month period in the prior year
are largely due to increases in the number of sales personnel, commissions as a
result of higher revenue levels, and travel costs.

     Research and Development.  Research and development expenses increased 29%
to $1.7 million during the second quarter of 1998 from $1.3 million in the
second quarter of 1997.  For the six months ended June 30, 1998, research and
development expenses increased 33% to $3.2 million from $2.4 million for the
first six months of 1997.  Research and development expenses were 19% and 24% of
total revenue in the second quarter of 1998 and 1997, respectively, and 20% and
22% of total revenue during the six month periods ended June 30, 1998 and 1997,
respectively.  The absolute dollar increases in the current quarter over the
prior year and for the current six months over the comparable six month period
in the prior year are largely due to the increase in the number of employees,
including employees from the December 1997 SQLBench acquisition.

     General and Administrative.  General and administrative expenses increased
16% to $905,000 during the second quarter of 1998 from $783,000 in the second
quarter of 1997.  For the six months ended June 30, 1998, general and
administrative expenses increased 13% to $1.8 million from $1.6 million for the
first six months of 1997.  General and administrative expenses were 10% and 15%
of total revenue during the second quarter of 1998 and 1997, respectively, and
11% and 15% of total revenue during the six month periods ended June 30, 1998
and 1997, respectively.  The absolute dollar increases in the current quarter
over the prior year and for the current six months over the comparable six month
period in the prior year are largely attributable to increased employment of
both executive and administrative personnel and increased professional fees
associated with the growth of the Company.

     Amortization of Goodwill.  Amortization of goodwill increased 100% to
$377,000 during the second quarter of 1998 from $0 in the second quarter of
1997.  For the six months ended June 30, 1998, amortization of goodwill
increased 100% to $753,000 from $0 for the first six months of 1997.
Amortization of goodwill was 4.3% and 0% of total revenue during the second
quarter of 1998 and 1997, respectively, and 4.6% and 0% of total revenue during
the six-month periods ended June 30, 1998 and 1997, respectively.  The absolute
dollar increases in amortization are attributable to the acquisition of SQLBench
in the fourth quarter of 1997.

OTHER INCOME, NET

     Other income, net decreased 24% to $413,000 during the second quarter of
1998 from $546,000 in the second quarter of 1997.  For the six months ended June
30, 1998, other income, net decreased 25% to $814,000 from $1.1 million for the
first six months of 1997.  These decreases are largely due to interest expense
of $97,000 and $191,000 recognized in the second quarter of 1998 and the six
month period ended June 30, 1998, respectively, related to the subordinated
notes payable which were issued in December 1997.

PROVISION FOR INCOME TAXES

     The Company recorded provisions for state income taxes of $30,000 and
$8,000 for the second quarter of 1998 and 1997, respectively, and a total of
$56,000 for the six month periods ended June 30, 1998 and 1997, but no
provisions for federal income taxes due to utilization of net operating loss
carryforwards.

LIQUIDITY AND CAPITAL RESOURCES

     In the first six months of 1998, the Company used $1.1 million for
operating activities, resulting from the growth in accounts receivable and other
current assets, offset by net income and deferred revenue.

     The Company generated $13.7 million from investing activities in the first
six months of 1998, mainly as a result of maturities of short-term investments.

     The Company generated funds from financing activities of $1.4 million in
the first six months of 1998, related to the exercise of stock options and
issuance of stock pursuant to the employee stock purchase plan.

     In April 1998, the Company entered into a nine year lease commitment for
40,500 to 67,500 square feet, effective August 1, 1998, which expires in October
2007.  The Company has the right to terminate the lease on September 30, 2004
for a fee of approximately $2.2 million.

     Future minimum payments under the lease are as follows (in thousands):

     Long-term cash requirements, other than normal operating expenses, are
anticipated for the completion of the new corporate headquarters facility, the
development of new software products and enhancements of existing products, the
opening of additional international offices, and the possible acquisition of
software products or technologies complementary to the Company's business.

     Assuming there is no significant change in the Company's business, the
Company believes that the existing cash and short-term investments as well as
cash flows from operations will be sufficient to meet its working capital
requirements for at least the next twelve months.

YEAR 2000 COMPLIANCE

     The Company recognizes that it must ensure that its products and operations
will not be adversely impacted by year 2000 software failures (the "Year 2000
issue") which can arise in time-sensitive software applications which utilize a
field of two digits to define the applicable year. In such applications, a date
using "00" as the year may be recognized as the year 1900 rather than the year
2000. In general, the Company expects to resolve Year 2000 issues through
planned replacement or upgrades. In addition, the Company expects that any costs
incurred to modify its internal systems will not be material. Although
management does not expect Year 2000 issues to have a material impact on its
business or future results of operations, there can be no assurance that there
will not be interruptions of operations or other limitations of system
functionality or that the Company will not incur significant costs to avoid such
interruptions or limitations.

IMPORTANT FACTORS RELATED TO FORWARD-LOOKING STATEMENTS AND ASSOCIATED RISKS

     This Quarterly Report on Form 10-Q/A contains forward-looking statements
within the meaning of Section 27A of the Securities Act of 1933 and Section 21E
of the Securities Exchange Act of 1934.  The Company's actual results could
differ materially from those set forth in the forward-looking statements.
Various important factors, including but not limited to the following, may cause
the Company's future results to differ materially from those set forth in the
forward-looking statements: risks associated with the Company's limited
operating history; the dependence upon license revenues from the Company's
principal products; uncertainties regarding the development of the automated
software testing marketplace; the dependence upon the growth of a viable
commercial marketplace for the Internet's World Wide Web and Internet-related
products; changes in technology and industry standards; the Company's ability to
develop and introduce product enhancements and new products; risks related to
the management of the Company's growth; risks related to the Company's ability
to integrate acquisitions already completed as well as others that may occur;
risks related to the development of the Company's sales and marketing strategy;
risks related to Year 2000 compliance of the Company's internal systems; the
Company's ability to attract, train and retain qualified personnel; the
development of an international market and distribution channel for the
Company's products; the Company's ability to develop strategic partnerships; the
timing of the receipt of orders from major customers; increased competition,
including competition from the recent consolidation in the automated software
quality market; and general economic conditions.  In addition, the Company has
significantly changed the executive management team and the sales management
team under the direction of a new Chief Executive Officer.  In conjunction with
these management changes, the Company has refocused its sales and marketing
approach to focus on e-commerce applications.  There can be no assurance that
the Company will be able to effectively manage such change.  Furthermore, a
significant portion of the Company's revenue within a quarter is typically not
realized until late in that quarter.  As a result, it may be difficult for the
Company to predict its total revenue for a quarter or to quickly adapt its
spending levels within a quarter to reflect changes in demand for its products.
The market price of the Company's common stock has been, and in the future will
likely be, subject to significant fluctuations in response to variations in
quarterly operating results and other factors, such as announcements of
technological innovations or new products by the Company or its competitors, or
other events.  For a more detailed discussion of those factors affecting future
operating results, see the discussion contained in the Company's Annual Report
on Form 10-K/A for the year ended December 31, 1997, under the heading "Certain
Factors Affecting Future Operating Results".
