                                    PART I

ITEM 1.   BUSINESS

GENERAL

     Segue Software, Inc. is a leader in automated testing for software
reliability.  The Company's products are used by quality assurance professionals
and software developers to improve software quality, reduce development costs
and shorten the time required to develop and deploy software applications.  The
Company's products integrate test planning, creation, execution, management and
analysis to provide automated functionality and load testing of software
applications. The Company's products are used to test software applications
across various components of distributed, multi-platform client/server systems
as well as applications deployed on the World Wide Web.

     During 1997, Segue introduced new technology to provide automated software
testing for Web-enabled software applications extending the Company's
distributed testing capabilities beyond distributed client/server applications
with GUI front ends.  Segue also began to focus on load testing in 1997, through
an OEM/reseller arrangement with a third party software vendor. On December 30,
1997, the Company acquired both the third party software vendor and the
developer of the product, SQLBench International, Inc. and ARC - Dr. Ambichl &
Dr. Reindl Communication GmbH (formerly named ARC Dr. Ambichl & Dr. Reindl OEG),
hereafter referred to as "SQLBench".  See Note B to the Consolidated Financial
Statements.  These new product offerings formed the basis for a significant
refocus of the Company's marketing and sales initiatives beginning in the fourth
quarter of 1997.

     In the fourth quarter of 1997, the Company began focusing its marketing and
sales efforts on the electronic commerce ("e-commerce") and Internet
applications market with a solution sales approach for its customers.  The
Company believes that it can provide its customers with an automated testing
solution which can be of strategic value.  This decision to refocus the
Company's marketing and sales efforts was based on the belief that this is a
fast-growing segment of the automated software testing market.  The Company
introduced its cross-browser regression testing tool, SilkTest, in May 1997 to
address this market.  The Company also believes that its Web load testing
product, SilkPerformer, introduced in September 1997, is positioned to model or
simulate load on Web-based applications for this market.

                                       2
<PAGE>
 
     In order to offer this testing solution consisting of products and
consulting, the Company reorganized its sales force structure beginning in the
fourth quarter of 1997. The Company formed an enterprise sales group consisting
of teams of one strategic sales representative and one technical support
engineer. This group focuses on e-commerce solution sales. At the same time, the
Company reconfigured its telesales force into a product sales group focused on
selling regression and load testing products primarily to the distributed
client/server market. This reorganization was accomplished under the direction
of a new domestic sales management team put in place in the fourth quarter of
1997.

     The new sales focus and structure was launched under the direction of a new
Chief Executive Officer who joined the Company in September 1997 and was fueled
in large part by the evolution of the Company's regression testing products
addressing Web-based applications. This new focus also emphasizes the Company's
load testing product line.

     Since these changes were implemented in the fourth quarter of 1997, the
Company does not have significant data to determine whether these initiatives
will be well received by its customers or whether the e-commerce market will
grow significantly.

     Segue was incorporated in California in 1988 and reincorporated in Delaware
in March 1996.

INDUSTRY BACKGROUND

     As businesses expand the use of technology to manage information and
processes, and as software has become a more important component in the delivery
of their products and services, consistent and effective operation of software
applications has become more critical to their success.  These applications are
increasingly deployed in both client/server configurations and on the World Wide
Web.  According to Brendan Conway of the Gartner Group, "Software, which
connects people to process, has become the blood supply to today's living
enterprise.  If it becomes infected, so does the business process of the
organization."  As client/server software is increasingly utilized to support
mission-critical applications, effective software quality management and testing
is required to avoid defects.  As Web-based applications are increasingly being
used to support commerce, the up-time reliability and accuracy of those commerce
applications are critical to the success of those companies.

     Unlike mainframe environments, where applications, operating systems and
hardware were designed by a single vendor as an integrated solution,
client/server systems and Web-based systems consist of component layers of
applications, middleware, operating systems, databases, browsers, servers,
processors and network technology designed separately by multiple vendors. For
example, in a client/server configuration, a Microsoft Windows95 client might
send requests to a router installed on a Microsoft NT server that distributes
them to an Oracle database located on a Sun Solaris server.  There is a higher
probability for application instability or failure when the component layers of
client/server applications and Web-based applications are developed separately
by multiple vendors and integrated to form a business system.

                                       3
<PAGE>
 
     The transition to client/server environments has occurred in two phases. In
the first phase, client/server application logic exists on either the client or
the server. Typically the business logic is supported by the client and only the
data resides on the database server. In the second phase, referred to as
distributed client/server, application logic and business data are distributed
among multiple client, middleware and server layers. Now Web-based, e-commerce
applications are being added to the client/server environments, adding another
layer of complexity to the environments.

     Distributed client/server computing and Web applications present enormous
challenges to quality assurance professionals and software developers.
Moreover, advances in client/server software development tools have enabled
rapid development of client/server applications.  The complexity of distributed
client/server environments, and rapid application development, greatly increase
the likelihood that a combination of events will cause an application or system
to fail or produce unintended results ("bugs").  At the same time, competitive
pressures force software developers to compress development schedules in order
to shorten time to deployment.

     To date, quality assurance professionals and software developers have
primarily used manual testing techniques to test software application functions
and features.  Manual testing is slow, tedious and difficult to replicate in a
systematic manner, and is often performed at the end of the development process
when bugs are difficult and costly to correct.  As a result, quality assurance
professionals and software developers have begun to invest in automated software
testing tools.

     Traditional automated testing tools, which are designed for a specific
component on a particular platform, do not adequately address the complexities
of distributed client/server computing.  First, they are not designed to
validate distributed application logic and data. Second, tests created by these
tools become obsolete when a component is replaced or upgraded. Third,
traditional automated testing tools are unable to recover when a bug is
encountered in the component being tested, meaning that truly unattended testing
in a distributed environment is impossible with such tools.  Finally, they do
not deliver the capability to design, create, manage and reuse tests across
multiple platforms and system configurations, resulting in additional costs and
time spent on the software development and quality assurance processes.

     In addition to automated testing tools, defect tracking and load testing
are important components of the automated testing solution. With integrated
defect tracking, the quality assurance department and the software development
organization can work more closely in the process of finding, tracking and
fixing software errors. By building load testing into the application testing
process early in the development cycle, the performance of the application in a
"real world" environment can be tested as well.

SERVICES

     The Company supplements all of its product offerings with training,
consulting and technical support services. The Company's services are designed
to promote a clear and consistent approach to automated testing and to
facilitate the penetration of the Company's products into a broader market. As
of February 28, 1998, these services were provided by 23 employees.

     Training and Consulting. The Company offers training courses and consulting
services in support of its product families. The training courses are held
regionally in selected U.S. cities or at the customer site. The Company has two
principal objectives for its fee-based training courses and consulting services:
to produce the agreed-upon deliverables for the projects and to enhance the
customers' understanding of the Company's methodologies and techniques. The
Company has recently begun to offer e-commerce testing consulting services in
order to assist companies in a more rapid and successful adoption of regression
and load testing for Web-based applications.

     Support Services. The Company offers annual maintenance contracts for an
annual fee to customers who have entered into license agreements for the use of
the Company's software products. The Company provides customer service and
support through its internal technical support organization. Support services
include the maintenance of the Company's software products in accordance with
specifications contained in the user's guide for such products and access to

                                       6
<PAGE>
 
technical support personnel. This support includes technical support through the
Company's internal customer support group via phone, fax and e-mail
communications. Customers who are under an active software maintenance contract
are entitled to product upgrades and enhancements, when and if released. The
Company's distributors and some of its channel partners provide initial
telephone support to end-users.

SALES AND MARKETING

     The Company sells its products through four channels: a direct sales force;
telesales representatives; a channel partner program; and international
distributors and resellers.  The Company has made a significant investment in
sales and marketing in each of the last two years. As of February 28, 1998, the
Company's sales and marketing force consisted of 69 employees.

     Direct Sales. The Company has historically relied principally on direct
sales of its products. The Company has recently structured its domestic direct
sales force into an enterprise sales group consisting of teams of one strategic
sales representative and one technical support engineer. As of February 28,
1998, the Company's direct sales force consisted of 33 employees. The Company
has nine sales offices throughout the United States and Canada and one sales
office in the United Kingdom. The Company intends to hire additional sales and
support personnel to broaden its direct selling and distribution capabilities.

     Telesales. The Company recently separated its telesales representatives
into a product sales group selling principally to the distributed client/server
market. As of February 28, 1998, the Company's telesales force totaled six
employees.

     Channel Partner Programs.  In 1995, the Company established its Channel
Partner Programs, which aim to generate revenues from alternate channels.  These
programs consist of the following: Value Added Resellers (VARs), Business
Integration Partners and Technology Integration Providers.  Current partners
include Andersen Consulting, Interim Technology and INTERSOLV.

     International Sales.  In international markets, the Company utilizes
distributors in ten countries, which are supported by six members of the
Company's international sales organization.  The Company derived approximately
11%, 8% and 7% of its total product sales from international customers in 1997,
1996 and 1995, respectively.

     In support of its sales efforts, the Company conducts sales training
courses, targeted marketing programs, including direct mail, public relations,
advertising, seminars, trade shows and telemarketing, and ongoing customer and
third party communications programs. The Company also seeks to stimulate
interest in computer and software quality management tools through a public
relations program, speaking engagements, white papers, technical notes and other
publications. The Company has established a home page on the Internet's World
Wide Web, where potential customers can access information about the Company and
its products.

BACKLOG

     The time between order and delivery of the Company's products is generally
quite short. The number of orders, as well as the size of individual orders, can
vary substantially from month to month.  Because of the short period between
order receipt and shipment of products, the Company typically does not have a
backlog of unfilled orders.

RESEARCH AND DEVELOPMENT

     The Company has made substantial investments in research and product
development.  The Company's research and development is conducted by project
teams consisting of development and quality assurance engineers and technical
writers.  The Company uses many of its own products and methodologies in its
development process.  The Company organizes development and quality assurance
schedules to optimize usage of automated tests by starting script development
very early in the development life cycle.  The Company's research and
development staff originates, produces and tests many of the Company's prototype
products.  The research and development department consults with the Company's
sales and marketing staff and utilizes the feedback from customer support and
training to ensure the satisfaction of its current customers. The Company also
licenses technology from vendors to be embedded in its product for resale or to
be resold as products by the Company.

     The Company's research and development organization for regression testing
products is located at the Company headquarters in Newton Centre, MA.  The
Company also has nine developers in Austria who are focused on the development
of load testing products.  These employees joined the Company as part of the
acquisition of SQLBench.  See Note B to the Consolidated Financial Statements.

     Research and development expenses were $4.9 million in 1997, $3.8 million
in 1996 and $2.3 million in 1995. The staff grew to 51 employees as of February
28, 1998 from 35 as of February 28, 1997. The Company intends to continue making
significant investments in research and development to develop new products,
expand the capabilities of its Web application testing products and to
internationalize all of the Company's products.

COMPETITION

     The market for software quality management tools is new, intensely
competitive, rapidly evolving and subject to rapid technological change.  The
Company's competitors offer a variety of products and services to address this
market.  The Company currently encounters direct competition from a number of
public and private companies such as Mercury Interactive Corporation, Rational
Software Corporation and Compuware Corporation.  In addition, the possible
entrance of new competitors may intensify competition in the software quality
management market.  Many of the Company's current and possible future
competitors have significantly greater financial, technical, marketing and other
resources than the Company, and many have well established relationships

                                       8
<PAGE>
 
with current and potential customers of the Company. It is also possible that
alliances among competitors may emerge and rapidly acquire significant market
share. The Company also expects that competition will increase as a result of
software industry consolidations. Increased competition may result in price
reductions, reduced gross margins and loss of market share, any of which would
materially adversely affect the Company's business, operating results and
financial condition. There can be no assurance that the Company will be able to
compete effectively against current and future competitors.

     The Company believes that the principal competitive factors affecting its
market include product features and functionalities, such as flexibility,
scalability, ease-of-integration, ease-of-implementation, ease-of-use, quality,
performance, price and total cost of ownership; customer service and support;
company reputation and financial viability; and effectiveness of sales and
marketing efforts.  Although the Company believes that it currently competes
effectively with respect to such factors, there can be no assurance that the
Company will be able to maintain its competitive position against current and
potential competitors.

PROPRIETARY TECHNOLOGY

     The Company primarily relies upon a combination of trademark, copyright and
trade secret laws and employee and third-party non-disclosure agreements to
protect its proprietary rights in its products.  The Company has one patent, but
there can be no assurance that this patent would be upheld if challenged.  There
can be no assurance that the Company's competitors will not independently
develop technologies that are substantially equivalent or superior to the
Company's technology.  There can also be no assurance that the measures taken by
the Company to protect its proprietary rights will be adequate to prevent
misappropriation of the technology or independent development by others of
similar technology.  In addition, the laws of various countries in which the
Company's products may be sold may not protect the Company's products and
intellectual property rights to the same extent as the laws of the United
States.  There can be no assurance that third parties will not assert
intellectual property infringement claims against the Company or that any such
claims will not require the Company to enter into royalty arrangements or result
in costly litigation.  The Company is not aware of any patent infringement
charge or any violation of other proprietary rights claimed by any third party
relating to the Company or the Company's products.  However, the computer
software market is characterized by frequent and substantial intellectual
property litigation.  Intellectual property litigation is complex and expensive,
and the outcome of such litigation is difficult to predict.  The Company
believes that, due to the rapid pace of technological innovation for software
quality management products, the Company's ability to establish and maintain a
position of technology leadership in the industry is dependent more upon the
skills of its development personnel than upon the legal protections afforded its
existing technology.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS

     Segue Software, Inc. is a leader in automated testing for software
reliability.  The Company's products are used by quality assurance professionals
and software developers to improve software quality, reduce development costs
and shorten the time required to develop and deploy software applications.  The
Company's products integrate test planning, creation, execution, management and
analysis to provide automated functionality and load testing of software
applications.  The Company's products are used to test software applications
across various components of distributed, multi-platform client/server systems
as well as applications deployed on the World Wide Web.

     During 1997, Segue introduced new technology to provide automated software
testing for Web-enabled software applications extending the Company's
distributed testing capabilities beyond distributed client/server applications
with GUI front ends.  Segue also began to focus on load testing in 1997, through
an OEM/reseller arrangement with a third party software vendor.  On December 30,
1997, the Company acquired both the third party software vendor and the
developer of the product, SQLBench International, Inc. and ARC - Dr. Ambichl &
Dr. Reindl Communication GmbH (formerly named ARC Dr. Ambichl & Dr. Reindl OEG),
hereafter referred to as "SQLBench".  See Note B to the Consolidated Financial
Statements.  These new product offerings formed the basis for a significant
refocus of the Company's marketing and sales initiatives beginning in the fourth
quarter of 1997.

     The Company began focusing its marketing and sales efforts on the e-
commerce and Internet applications market with a solution sales approach for its
customers. By doing so, the Company believes it can provide its customers with
an automated testing solution which can be of strategic value.

     The new sales focus was launched under the direction of a new Chief
Executive Officer who joined the Company in September 1997 and was fueled in
large part by the evolution of the Company's regression testing products to
address Web-based applications. This new focus also emphasizes the Company's
load testing product line.

REVENUE

TOTAL REVENUE

     Total revenue increased 28% to $21.8 million in 1997 and 53% to $17.0
million in 1996 from $11.1 million in 1995.

     Total revenue primarily consists of software and services revenue. Software
revenue consists of revenue from the granting of perpetual licenses to use the
Company's products. Services revenue consists of revenue from maintenance,
training and consulting. The Company sells its licenses through its direct sales
force, telesales, international distributors and channel partners.

                                       15

REVENUE FROM SOFTWARE

     Software revenue increased 25% to $15.8 million in 1997 and 51% to $12.6
million in 1996 from $8.3 million in 1995.  The increases in software revenue
are primarily the result of increased unit shipments in each of the respective
periods.  These increased unit shipments were due to an increase in the demand
for automated testing products; the introduction by the Company of new and
upgraded products; increased market acceptance of the families of products
including its Web application testing products and load testing products
introduced in 1997; and expansion of the Company's sales and marketing
activities.

     In 1997, the Company introduced a Web application testing product,
SilkTest, and load testing products, SilkPerformer and QA Performer. Revenues
from these three new products represented 18%, 5% and 3% of total product
revenue, respectively.

     The increase in unit shipments came largely through the direct domestic
channel.  Revenue from the domestic indirect channel accounted for 8%, 5% and 5%
of total product revenue in 1997, 1996 and 1995, respectively.  International
revenue accounted for 11%, 8% and 7% of total product revenue in 1997, 1996 and
1995, respectively.

     In addition, the mix of software license revenue changed in 1997.  Prior to
1997, the Company had no revenue from either the e-commerce testing or load
testing markets.  Revenues from those markets totaled 23% and 8% of total
product revenue in 1997.

REVENUE FROM SERVICES

     Services revenue increased 37% to $6.0 million in 1997 and 67% to $4.4
million in 1996 from $2.6 million in 1995. The increases in revenue from
services are principally the result of the increased volume of maintenance,
training and consulting services, primarily due to the expansion of the
installed base of users of the Company's products. Maintenance revenue increased
46% to $4.1 million in 1997 and 75% to $2.8 million in 1996 from $1.6 million in
1995. Training and consulting revenue increased 19% to $1.9 million in 1997 and
60% to $1.6 million in 1996 from $1.0 million in 1995.

COST OF REVENUE

COST OF SOFTWARE

     Cost of software includes documentation reproduction costs, product
packaging, product media, employment costs for processing and distribution,
amortization of intangible assets and royalties due to third parties for their
software included in the Company's products or sold separately by the Company.
These costs increased 68% to $1,095,000 in 1997 and 107% to $651,000 in 1996
from $315,000 in 1995. As a percentage of software revenue, cost of software

                                       16
<PAGE>
 
was 7% in 1997, 5% in 1996 and 4% in 1995. The increase in the cost of software
revenue in each period primarily reflects the increased volume of units sold.
The increase in the cost of software revenue in 1997 is also attributable to
royalty expense related to the sale of the Company's load testing products which
were licensed from a third party software provider until December 30, 1997 (see
Note J to the Consolidated Financial Statements).

COST OF SERVICES

     Cost of services consists principally of employment-related costs for the
Company's customer support staff, which provides services under maintenance
contracts, and the Company's training and consulting staff, as well as the cost
of materials and facilities used in training customers.  Cost of services
increased 52% to $2.6 million in 1997 and 43% to $1.7 million in 1996 from $1.2
million in 1995.  As a percentage of services revenue, cost of services was 43%,
39% and 45% in 1997, 1996 and 1995, respectively.  The increases in the cost of
services are largely the result of the increase in the number of employees in
both the training and consulting and technical support groups, from 18 employees
as of February 28, 1997 to 23 employees as of February 28, 1998.  This increase
is also attributable to costs related to the delivery of training and consulting
services, such as travel and equipment rental.  The Company expects to expand
its customer support, training and consulting capabilities in 1998.

OPERATING EXPENSES

SALES AND MARKETING

     Sales and marketing expenses consist primarily of salaries, commissions and
related costs of Company personnel and promotional marketing programs, including
advertising, brochures, direct mail programs and seminars.  Sales and marketing
expenses increased 40% to $11.9 million in 1997 and 58% to $8.5 million in 1996
from $5.4 million in 1995.  The principal reasons for the increases in sales and
marketing expenses in all periods were increases in the number of sales and
marketing personnel, increases in commissions as a result of higher revenue
levels and increases in promotional marketing programs.  The staff grew to 69
employees as of February 28, 1998 from 52 as of February 28, 1997.  Sales and
marketing expenses increased as a percentage of revenue to 55% in 1997 from 50%
in 1996 and 49% in 1995, respectively, as a result of significant increases in
the number of sales staff hired by the Company and in the Company's promotional
marketing programs.  The sales organization was restructured in the fourth
quarter of 1997 to focus on the Company's e-commerce market initiative.
Historically, the Company's costs for the sales and marketing organization have
totaled between 40% and 50% of revenue on an annual basis.  However, in 1997, as
noted above, the cost of the sales and marketing organization grew to 55% of
revenue.  These increases are largely related to the restructuring of the sales
organization to focus on e-commerce solution selling and the hiring of a new
sales management team.  The Company intends to continue this increase in
spending for sales and marketing in 1998, both internationally and domestically,
principally related to hiring additional sales personnel and the related travel,
training and commission costs.

                                       17
<PAGE>
 
     There can be no assurance that these increased expenditures or the re-
structuring of the sales organization will result in increased revenue or
improvement in the effectiveness of the sales organization.

RESEARCH AND DEVELOPMENT

     Research and development expenses consist primarily of the employment-
related costs for engineering and technical personnel associated with developing
new products or enhancing existing products, for quality assurance personnel and
for product documentation specialists to provide user product documentation and
tutorials. To date, all of the Company's internal costs for research and
development have been charged to operations as incurred since the amount of
software development costs qualifying for capitalization has been insignificant.
Research and development expenses increased 30% to $4.9 million in 1997 and 67%
to $3.8 million in 1996 from $2.3 million in 1995. The increases are mainly
attributable to increases in the number of research and development employees.
The staff grew to 51 employees as of February 28, 1998 from 35 as of February
28, 1997. The Company intends to continue making significant investments in
research and development to develop new products, expand the capabilities of its
Web application testing products and to internationalize all of the Company's
products.

     During 1997, the Company introduced several new products including SilkTest
(a regression testing product for Web applications), SilkPerformer (a load
testing product for Web applications) and QA Partner Blue (a Year 2000
regression testing product). Additionally, in January 1998, the Company further
enhanced its SilkTest product by adding support for the JAVA programming
language.

     As a result of the acquisition of SQLBench on December 30, 1997, the
Company now has nine developers located in Austria who are focusing on the
development and enhancement of the Company's load testing products.

GENERAL AND ADMINISTRATIVE

     General and administrative expenses consist principally of employment-
related costs for executive and administrative personnel, professional fees,
consulting fees, system support costs and other general corporate expenses.
General and administrative expenses increased 32% to $3.2 million in 1997 and
43% to $2.4 million in 1996 from $1.7 million in 1995. The increases in all
periods are attributable to increased employment of both executive and
administrative personnel and increases in professional fees, system support
costs and other general corporate expenses. The staff growth has occurred in
executive, finance and human resources and has been necessary to support the
growth of the Company. The Company anticipates that general and administrative
expenses will increase in 1998 due to the growth in management systems and
administrative infrastructure.

                                       18

NON-RECURRING CHARGES

     In the fourth quarter of 1997, the Company recognized a charge of $9.1
million related to the write-off of purchased research and development in
process in conjunction with the SQLBench acquisition and $718,000 consisting of
severance and accelerated vesting of options related to the resignation of the
Company's former President and Chief Executive Officer (see Note K to the
Consolidated Financial Statements).

     The non-recurring charge in 1995 totaled $449,000 and consisted of
severance and the purchase of vested options for common stock granted to the
Company's President and Chief Executive Officer who had held that position from
1991 until June 30, 1995.

LITIGATION SETTLEMENT

     On September 30, 1996, the Company entered into a definitive agreement with
a plaintiff to settle litigation brought against the Company and certain of its
current and former employees. The Company recorded a charge of $744,000 in the
third quarter of fiscal 1996 to cover the settlement and other expenses incurred
in connection therewith.

OTHER INCOME (EXPENSE), NET

     Other income (expense), net is comprised primarily of interest income from
cash, cash equivalents and short-term investments.  On April 2, 1996, the
Company completed an initial public offering of common stock and received net
proceeds of $39.5 million.  As a result of the Company's receipt and investment
of the offering proceeds, other income has increased substantially over prior
periods.  Prior to 1997, interest income was partially offset by interest
expense related to the Company's convertible debt. As of December 31, 1996, all
of the Company's convertible debt was converted into common stock of the
Company.

PROVISION FOR INCOME TAXES

     The Company had a provision for income taxes of $56,000 and $20,000 in 1997
and 1996, respectively, principally for state taxes.  There was no provision for
income taxes in 1995.  As of December 31, 1997, the Company had federal net
operating loss carryforwards of approximately $4.5 million and state net
operating loss carryforwards of $1.8 million as well as $821,000 of federal tax
credit carryforwards available for income tax purposes.  These carryforwards
generally expire in the years 1998 through 2012 and may be subject to annual
limitations as a result of changes in the Company's ownership.  Management of
the Company has evaluated the positive and negative evidence impacting the
realizability of its deferred tax assets, which are comprised principally of net
operating loss carryforwards and tax credits.  Based on the weight of the
available evidence, it is more likely than not that all of the deferred tax
assets will not be realized, and accordingly the deferred tax assets have been
fully reserved.  Management re-evaluates the positive and negative evidence on a
quarterly basis.

                                       19

NET INCOME (LOSS)

     For the year ended December 31, 1997, the Company had a net loss of
$9,588,000 compared with net income of $641,000 for the year ended December 31,
1996 and a net loss of $303,000 for the year ended December 31, 1995.

     Net income for 1997, excluding the non-recurring charges, would have been
$225,000.

LIQUIDITY AND CAPITAL RESOURCES

     Cash, cash equivalents and short-term investments decreased to $37.4
million as of December 31, 1997 from $41.2 million as of December 31, 1996. In
1996, cash, cash equivalents and short term investments increased from $442,000
as of December 31, 1995, primarily as a result of the funds raised in the
Company's initial public offering of common stock.

     The Company generated $1.4 million and $2.1 million from operations in 1997
and 1996, respectively. In 1997, funds provided by operating activities were
primarily affected by the growth in accounts receivable. In 1996, funds provided
by operating activities were primarily the result of net income and growth in
accrued expenses and deferred revenue, partially offset by growth in accounts
receivable and other current assets.

     The Company generated $13.6 million and utilized $35.4 million for
investing activities in 1997 and 1996, respectively. Funds generated in 1997
were largely the result of the maturity of short-term investments, partially
offset by $4.4 million related to the SQLBench acquisition and $1.3 million
related to capital expenditures for computer equipment, software and furniture.
The investing activities in 1996 involved the investment of the initial public
offering proceeds in short-term investments, generally in U.S. Government and
government agency securities, and the purchase of computer equipment, software
and furniture.

     The Company generated funds from financing activities of $925,000 and $40.0
million in 1997 and 1996, respectively. In 1997, funds generated from financing
activities resulted from the exercise of stock options. In 1996, the Company
generated $39.5 million from its initial public offering of common stock and
$445,000 from the exercise of stock options.

     In the second quarter of 1998, the Company expects to enter into a nine
year lease commitment for 40,500 to 67,500 square feet, effective August 1,
1998, at an annual rental rate of approximately $2.2 million. The lease 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.

     Long-term cash requirements, other than normal operating expenses, are
anticipated for the development of new software products and enhancements of
existing products, the opening of additional international offices, and the

                                      20
<PAGE>
 
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.

RECENT ACCOUNTING PRONOUNCEMENTS

     In June 1997, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) No. 130, "Reporting
Comprehensive Income". This statement requires that changes in comprehensive
income be shown in a financial statement that is displayed with the same
prominence as other financial statements. The statement is effective for annual
periods beginning after December 15, 1997, and the Company will adopt its
provisions in fiscal 1998. Reclassification for earlier periods is required for
comparative purposes. Management does not expect the statement to have a
material impact on the Company's financial disclosures.

     In June 1997, the FASB issued SFAS No. 131 ("SFAS 131"), "Disclosure about
Segments of an Enterprise and Related Information", which changes the manner in
which public companies report information about their operating segments. SFAS
131, which is based on the management approach to segment reporting, establishes
requirements to report selected segment information quarterly and to report
entity-wide disclosures about products and services, major customers, and the
geographic locations in which the entity holds assets and reports revenue.
Management is currently evaluating the effects of this change on its reporting
of segment information. The Company will adopt SFAS 131 for its fiscal year
ending December 31, 1998.

     In October 1997, Statement of Position 97-2, "Software Revenue Recognition"
("SOP 97-2"), was issued which provides guidance on applying generally accepted
accounting principles in recognizing revenue on software transactions. SOP 97-2
is effective for transactions entered into in fiscal years beginning after
December 15, 1997. The Company will adopt the guidelines of SOP 97-2 as of
January 1, 1998 and does not expect adoption to have a material impact on the
Company's financial results.

CERTAIN FACTORS AFFECTING FUTURE OPERATING RESULTS

     Statements made or incorporated in this Form 10-K include a number of
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. Forward-
looking statements include, without limitation, statements containing the words
"anticipates", "believes", "expects", "intends", "future" and words of similar
import which express management's belief, expectations or intentions regarding
the Company's future performance. The Company's actual results could differ
materially from those set forth in the forward-looking statements. Certain
factors that might cause such a difference are discussed below.

                                      21
<PAGE>
 
Short Operating History; Accumulated Deficit. 

     The Company was founded in 1988 to provide software porting services to
independent software vendors. In 1992, the Company reorganized its business to
focus on the development and marketing of automated testing software for the
quality assurance market. The Company shipped its first automated testing
product, QA Partner, in the quarter ended March 31, 1993. Accordingly, the
Company has a limited operating history and, although the Company has
experienced growth in recent periods, continued growth at the same rate is not
sustainable and is not necessarily indicative of future operating results.
Losses have resulted in an accumulated deficit of approximately $12.7 million as
of December 31, 1997. The Company had a net loss of $303,000 in 1995, net income
of $641,000 in 1996 and a net loss of $9.6 million in 1997, which includes a
charge of $9.1 million for purchased research and development in process. The
limited operating history of the Company makes the prediction of future results
difficult and, therefore, there can be no assurance that the Company will
sustain revenue growth or achieve profitability on a consistent basis.

Potential Fluctuations in Operating Results. 

     The Company may experience significant fluctuations in future quarterly
operating results, which may be caused by many factors, including: the timing of
introductions of new products or product enhancements by the Company or its
competitors; personnel changes; the size and timing of individual orders;
software bugs or other product quality problems; competition and pricing;
customer order deferrals in anticipation of new products or product
enhancements; reduction in demand for automated software testing products;
changes in operating expenses; product mix; and general economic conditions. A
substantial portion of the Company's operating expenses are related to
personnel, facilities and marketing programs. The level of spending for such
expenses cannot be adjusted quickly and is based, in significant part, on the
Company's expectations of future revenues. If actual revenue levels are below
management's expectations, results of operations are likely to be adversely
affected. In addition, the Company does not typically experience order backlog.
Furthermore, the Company has often recognized a substantial portion of its
revenues in the last month of a quarter, with these revenues frequently
concentrated in the last weeks or days of a quarter. As a result, product
revenues in any quarter are substantially dependent on orders booked and shipped
in the latter part of that quarter, and revenues for any future quarter are not
predictable with any significant degree of accuracy. For these reasons, the
Company believes that period-to-period comparisons of its results of operations
are not necessarily meaningful and should not be relied upon as indications of
future performance. Moreover, although the Company has not historically
experienced seasonal fluctuations in its revenue or results of operations, such
fluctuations are not uncommon in the software industry and may affect the
Company in the future.

Dependence on Principal Product. 

     To date, the Company has derived substantially all of its revenues from
licenses of QA Partner and related products and from fees for related services.
As a result, any factors adversely affecting the sales of QA Partner, such as
increased price competition or the introduction of technologically superior
products, could have a material adverse effect on the Company. The Company's
future financial performance will depend in significant part on its ability to
develop and introduce new releases of QA Partner with enhanced features and
functionalities and related products. In 1997, the Company introduced a Web
application testing product, SilkTest, and load testing products, SilkPerformer
and QA Performer. Revenues from these three new products represented 18%, 5% and

                                      22
<PAGE>
 
3% of total product revenue, respectively. The Company has refocused its sales
and marketing organization on the sale of these new products with an emphasis on
the e-commerce market. There can be no assurance that these products will be
successfully developed or achieve market acceptance.

Emerging Market.

     The market for automated software testing products is relatively new and
undeveloped. Marketing and sales techniques in the automated software testing
marketplace, as well as the bases for competition, are not well established.
There can be no assurance as to the extent that a significant market for
automated software testing products will develop or the extent to which the
Company's products will be accepted in that market. Although the Company
believes that the current trend toward increased use of automated software
testing will continue, a majority of software testing is still carried out
manually, and there can be no assurance that the automated software testing
market will enjoy continued growth.

     The commercial market for products and services designed for use on the
Internet, Intranet and Extranet has only recently begun to develop. The success
of the Company's products focused on e-commerce and Internet applications will
depend on the growth of the market and on the Company's ability to continue to
enhance its products to work with all of the prevalent technologies driving
Internet applications. There can be no assurance that the Company will be able
to effectively adapt its products to the prevalent technologies being used on e-
commerce applications or to successfully compete in the market for Internet-
related products and services.

Management of Growth.

     The Company has recently experienced a period of rapid growth, including
increases in the number of orders, customers and employees. Such growth has
placed, and may continue to place, strains on the Company's management,
operations and systems. The Company's ability to compete effectively will
depend, in part, upon its ability to expand, improve and effectively utilize its
operational, management, marketing, sales and financial systems as necessitated
by changes in the Company's business. Any failure by the Company's management to
effectively anticipate, implement and manage the changes required to sustain the
Company's growth could have a material adverse effect on the Company's business,
financial condition and results of operations. 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.

Management of Growth Through Acquisitions.

     The Company's product range and customer base have increased in the recent
past due in part to acquisitions. The Company may acquire additional businesses
or product lines in the future. The probability of success of any acquisition
may be dependent upon the Company's ability to integrate the acquired business
or products successfully and to retain key personnel associated with the
acquisition. Failure to do so, or a material increase in the cost of
integration, could cause actual results to differ from those projected in
management's forward-looking statements.

Year 2000 Compliance.

     The Year 2000 compliance issue concerns the inability of computerized
information systems to accurately calculate, store or use a date after 1999.
This could result in a system failure or miscalculations causing disruptions of
operations.

     The Company is in the process of conducting an assessment of its core
internal and external computer information systems and is taking the necessary
steps to understand the nature and extent of the work required to make its
systems, in those situations in which the Company is required to do so, Year
2000 compliant. These steps may require the Company to modify, upgrade or
replace some of its internal financial and operational systems. The total cost
of bringing all internal systems, equipment and operations into Year 2000
compliance has not been fully quantified. The Company continues to evaluate the
estimated costs associated with these compliance efforts. While these efforts
involve additional costs, the Company believes, based on available information,
that these costs will not have a material adverse effect on its business,
financial condition or results of operations. However, if these efforts are not
completed on time, or if the cost of updating or replacing the Company's
information systems exceeds the Company's current estimates, the Year 2000 issue
could have a material impact on the Company's ability to meets its financial and
reporting requirements and/or on its financial results. Further, no estimates
can be made as to any potential adverse impact resulting from the failure of
third-party service providers and vendors to prepare for the Year 2000. The
Company is attempting to identify those risks as well as to receive compliance
certificates from all third parties that have a material impact on the Company's
operations, but the cost and timing of third party Year 2000 compliance is not
within the Company's control and no assurances can be given with respect to the
cost or timing of such efforts or the potential effects of any failure to
comply.

Rapidly Changing Technology; New Products; Risk of Product Defects.

     The market for computer software products is generally characterized by
rapidly changing technology and frequent new product introductions that can
render existing products obsolete or unmarketable. The Company believes that a
major factor in its future success will be its ability to develop and introduce
in a timely manner enhancements to its existing products and new products that
will gain market acceptance. If the Company is unable to introduce new products
and respond to industry changes on a timely basis, its business could be
materially adversely affected. Software products as complex as those offered by
the Company may contain undetected errors or failures when first introduced or
as new versions are released. Although the Company has not experienced material
adverse effects resulting from undetected errors in the past, there can be no
assurance that errors will not be found in new products after commencement of
commercial shipments, resulting in loss of or delay in market acceptance, which
could have a material adverse effect upon the Company's business, financial
condition and results of operations. Further, because the Company is in the
quality assurance business, any errors in its software could harm the Company's
reputation in the quality assurance software market and make it more difficult
for the Company to sell its products.

Competition.

     The market for software quality management tools is new, intensely
competitive and subject to rapid technological change. The Company expects
competition to intensify in the future. The Company currently encounters direct
competition from a number of public and private companies including Mercury
Interactive Corporation, Rational Software Corporation and Compuware 

                                      24
<PAGE>
 
Corporation. Due to the expansion of the market for software quality management
tools, the Company may face competition from new entrants in the software
quality management industry, possibly including the Company's resellers or
current customers. There can be no assurance that the Company's current and
potential competitors will not develop software quality management tools that
may be more effective or achieve greater market acceptance than the Company's
current or future products or that the Company's technologies and products would
not be rendered obsolete by such developments. Many of the Company's current and
potential competitors have longer operating histories, greater name recognition,
larger installed customer bases, and significantly greater financial, technical
and marketing resources than the Company. The Company may also face increased
competition from the recent consolidation of several companies in the automated
software quality market. As a result, these competitors may be able to adapt
more quickly to new or emerging technologies and changes in customer
requirements, or to devote greater resources to the promotion and sale of their
products than the Company. An increase in competition could result in price
reductions and loss of market share. Such competition and any resulting
reduction in profitability could have a material adverse effect on the Company's
business, financial condition and results of operations.

Dependence on Key Personnel.

     The Company's success depends upon its ability to attract and retain highly
skilled technical, managerial and sales personnel. Competition for such
qualified sales, marketing and software development personnel in the computer
industry in general, and the automated software testing industry in particular,
is intense. Future results will depend on the Company's ability to attract and
retain such personnel, and the failure to do so could have a material adverse
effect on the Company's ability to develop and market competitive products and
its ability to achieve projected operating results.

International Activities.

     The Company derived approximately 11% of its total product sales from
international customers in 1997. The international market for software products
is highly competitive and the Company expects to face substantial competition in
this market from established and emerging companies. Risks inherent in the
Company's international business activities also include currency fluctuations,
imposition of government controls, export license requirements, restrictions on
the export of critical technology, political and economic instability, tailoring
of products to local requirements, trade restrictions, changes in tariffs and
taxes, difficulties in staffing and managing international operations, longer
accounts receivable payment cycles and the burdens of complying with a wide
variety of foreign laws and regulations. To the extent that the Company is
unable to expand international sales in a timely and cost-effective manner, the
Company's business could be materially adversely affected.

Development of Indirect Channels; Potential for Channel Conflict.

     Although the Company has not historically sold significant amounts of its
products through indirect channels, the Company intends to continue to develop
channel sales as part of its growth strategy. In 1995, the Company established
its Channel Partner Program. The Company licenses its products to its channel
partners at a discount and such partners relicense the products to end-users.
The Company's agreements with its channel partners are non-exclusive and provide
the channel partners with 60-day price protection. Because the Company's channel
partners generally order the Company's products after they have received
purchase orders, there is no requirement that the Company repurchase any 


                                      25
<PAGE>
 
product. The Company selects its channel partners based on the partner's
financial viability, product expertise and market focus. In order for the
Company's strategy to broaden market penetration through its Channel Partner
Program to be successful, the Company must increase its unit sales to offset the
discount it is providing the channel partners. There can be no assurance that
the Company will succeed in the development of these channels. Moreover, selling
through indirect channels may limit the Company's contact with the end users of
its products. As a result, the Company's ability to accurately forecast sales,
evaluate customer satisfaction and recognize emerging customer requirements may
be hindered and its ability to develop and maintain customer goodwill may be
limited. In addition, the Company's strategy of marketing its products directly
to end users and indirectly through its channel program and through distributors
may result in distribution channel conflicts. Although the Company has attempted
to manage its distribution channels in a manner to avoid potential conflicts,
there can be no assurance that channel conflicts will not materially adversely
affect its relationships with existing channel partners or distributors or
adversely affect its ability to attract new channel partners and distributors.
In addition, there can be no assurance that the Company's resellers will be able
to effectively market the Company's products or that they will not commence the
sale of competitive products. In 1996, the Company entered into an OEM
arrangement with INTERSOLV whereby INTERSOLV has the right to resell QA Partner
and related products to its customers. The Company has no assurance that this
will be a successful sales channel for the Company's products or that it will
not result in significant channel conflict.

Product Liability.

     In selling its products, the Company relies primarily on "shrink wrap"
licenses that contain, among other things, provisions protecting against the
unauthorized use, copying and transfer of the licensed program and limiting the
Company's exposure to potential product liability claims. However, these
licenses are not signed by the licensees and the provisions of these licenses,
including the provisions limiting the Company's exposure to product liability
claims, may therefore be unenforceable under the laws of certain jurisdictions.

Intellectual Property and Proprietary Rights.

     The Company currently relies on a combination of trademark, copyright and
trade secret laws and contractual provisions to protect its proprietary rights
in its products. The Company presently has no registered copyrights. The Company
has a patent but there can be no assurance that the patent would be upheld if
challenged. There can be no assurance that the Company's competitors will not
independently develop technologies that are substantially equivalent or superior
to the Company's technology. There can also be no assurance that the measures
taken by the Company to protect its proprietary rights will be adequate to
prevent misappropriation of the technology or independent development by others
of similar technology. In addition, the laws of various countries in which the
Company's products may be sold may not protect the Company's products and
intellectual property rights to the same extent as the laws of the United
States. There can be no assurance that third parties will not assert
intellectual property infringement claims against the Company or that any such
claims will not require the Company to enter into royalty or cross-license
arrangements or result in costly litigation. In the event of litigation to
determine the validity of any third party claims, such litigation could result
in significant expense to the Company and divert the efforts of the Company's
technical and management personnel, whether or not such litigation is determined
in favor of the Company.

Stock Market Volatility.

     Market prices for securities of software companies have generally been
volatile. In particular, the market price of the Company's common stock has been
and may continue to be subject to significant fluctuations as a result of
factors affecting the computer industry or the securities markets in general.
These factors include, but are not limited to, quarterly variations,
announcements of technological innovations by the Company or competitors,
announcements of mergers or acquisitions by the Company or competitors, changes
in prices by the Company or competitors, change in product mix, and change in
revenue or revenue growth rates for geographic areas or products.

                       REPORT OF INDEPENDENT ACCOUNTANTS



To the Board of Directors and
Stockholders of Segue Software, Inc.:

We have audited the accompanying consolidated balance sheets of Segue Software,
Inc. as of December 31, 1997 and 1996, and the related consolidated statements
of operations, stockholders' equity and cash flows for each of the three years
in the period ended December 31, 1997.  These financial statements are the
responsibility of the Company's management.  Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Segue Software,
Inc. as of December 31, 1997 and 1996, and the consolidated results of its
operations and its cash flows for each of the three years in the period ended
December 31, 1997, in conformity with generally accepted accounting principles.

A.   DESCRIPTION OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES:

Description of Business

     The Company develops, markets and supports integrated software solutions
for the automated functionality and load testing and quality management of
client/server software applications. The Company also provides maintenance,
training and consulting services in support of its product offerings. The
Company operates in one industry segment and no customer accounted for 10% or
more of total revenue in 1997, 1996 or 1995.

Principles of Consolidation

     The consolidated financial statements include the accounts of the Company
 and its subsidiaries. All significant intercompany transactions and balances
 have been eliminated in consolidation.

Revenue Recognition

     Revenue from software license fees is recognized upon shipment and receipt
of a signed purchase order or contract. At the time the Company recognizes
revenue from the sale of software products, collection is probable, no
significant vendor obligations remain and the costs of insignificant support
obligations, if any, are accrued. Maintenance revenue associated with initial
product license contracts is recognized ratably over the initial term, which is
generally one year. Maintenance revenue for annual contracts is deferred and
recognized ratably over the term of agreement. Revenue from training and
consulting services is recognized as the related services are performed. Royalty
revenue is recognized based upon the sale of the related products.

     The Company typically does not grant to its customers a contractual right
to return software products. When approved by management, however, the Company
has accepted returns of certain software products and has provided an allowance
for those specific products. The Company also provides reserves for customer
receivable balances which are considered potentially uncollectible. The
Company's allowances amounted to $345,000, $200,000 and $150,000 as of December
31, 1997, 1996 and 1995, respectively. The provision charged to general and
administrative expenses was $362,000, $489,000 and $249,000 in 1997, 1996 and
1995, respectively, and write-offs against the allowances were $217,000,
$439,000 and $139,000 in 1997, 1996 and 1995, respectively.

Deferred Revenue

     Service revenue (maintenance, training and consulting) which is not yet
earned is included in deferred revenue.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)


Research and Development and Software Development Costs

     Research and development expenditures are charged to operations as
incurred. Software development costs subsequent to the establishment of
technological feasibility are capitalized and amortized to cost of software.
Based on the Company's product development process, technological feasibility is
established upon completion of a working model. Costs incurred by the Company
between completion of the working model and the point at which the product is
ready for general release have been insignificant.

Income Taxes

     The Company uses the liability method of accounting for income taxes. Under
this method, deferred tax liabilities and assets are determined based on the
differences between the tax and financial reporting basis of assets and
liabilities and are measured using the tax rates and laws that will be in effect
when the differences are expected to reverse. The Company provides a valuation
allowance against net deferred tax assets if, based upon the available evidence,
it is more likely than not that some or all of the deferred tax assets will not
be realized.

Cash Equivalents and Short-Term Investments

     The Company considers all highly liquid investments purchased with a
maturity of three months or less to be cash equivalents. Short-term investments
are those with maturities in excess of three months but less than one year. All
cash equivalents and short-term investments have been classified as available-
for-sale and are reported at fair value with unrealized gains and losses
included in stockholders' equity. For the years ended December 31, 1997 and
1996, unrealized gains and losses on available-for-sale securities were
insignificant.

Property and Equipment

     Property and equipment are stated at cost. Expenditures for major
improvements which substantially increase the useful lives of assets are
capitalized. Repair and maintenance costs are expensed as incurred. Depreciation
is provided on a straight-line basis over the useful lives of the assets,
generally three to five years. Amortization of leasehold improvements is
computed on a straight-line basis over the remaining term of the lease.

     Upon retirement or sale, the cost of the assets disposed and the related
accumulated depreciation and amortization are removed from the accounts and any
resulting gain or loss is included in the determination of net income.

Completed Technology and Other Assets

     Completed technology of $1.0 million is included in other assets and is
carried at cost less accumulated amortization, which is being provided on a
straight-line basis over a period of three years, its estimated useful life (see
Note B).

     Long-lived assets to be held and used are recorded at cost. Management
reviews long-lived assets and the related intangible assets for impairment
whenever events or changes in circumstances indicate the carrying amount of such
assets may not be recoverable. Recoverability of these assets is determined by
comparing the forecasted undiscounted net cash flows of the operation to which
the assets relate, to the carrying amount including associated intangible assets
of such operation. In addition, the Company's evaluation considers non-financial
data such as market trends, product development cycles and changes in
management's market emphasis.

Concentration of Credit Risk

     The Company invests its cash, cash equivalents and short-term investments
primarily in U.S. Government and government agency securities, investment-grade
commercial paper and money market accounts. The Company has established
guidelines relative to credit ratings, diversification and maturities that
maintain safety and liquidity. The Company has not experienced any losses on its
cash, cash equivalents and short-term investments to date.

     The Company sells its products principally through a direct sales force
domestically and through distributors outside of the United States to customers
in a broad range of industries. The Company performs ongoing credit evaluations
of its customers but does not require collateral or other security to support
customer receivables. The Company maintains reserves for credit losses and such
losses have been within management's expectations.

Use of Estimates

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results may differ from those estimates.

Reclassification

     Certain prior year amounts have been reclassified to conform to the current
year presentation.

Stock-Based Compensation

     Statement of Financial Accounting Standards No. 123 ("SFAS 123"),
"Accounting for Stock-Based Compensation", allows companies to either account
for stock-based compensation under the provisions of SFAS 123 or under the
provisions of Accounting Principles Board Opinion No. 25 ("APB 25"), "Accounting
for Stock Issued to Employees", but requires pro forma disclosure in the notes
to the financial statements as if the measurement provisions of SFAS 123 had
been adopted. The Company has continued to account for its stock-based

compensation in accordance with the provisions of APB 25.

Recent Accounting Pronouncements

     In June 1997, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) No. 130, "Reporting
Comprehensive Income". This statement requires that changes in comprehensive
income be shown in a financial statement that is displayed with the same
prominence as other financial statements. The statement is effective for annual
periods beginning after December 15, 1997, and the Company will adopt its
provisions in fiscal 1998. Reclassification for earlier periods is required for
comparative purposes. Management does not expect the statement to have a
material impact on the Company's financial disclosures.

     In June 1997, the FASB issued SFAS No. 131 ("SFAS 131"), "Disclosure about
Segments of an Enterprise and Related Information", which changes the manner in
which public companies report information about their operating segments. SFAS
131, which is based on the management approach to segment reporting, establishes
requirements to report selected segment information quarterly and to report
entity-wide disclosures about products and services, major customers, and the
geographic locations in which the entity holds assets and reports revenue.
Management is currently evaluating the effects of this change on its reporting
of segment information. The Company will adopt SFAS 131 for its fiscal year
ending December 31, 1998.

     In October 1997, Statement of Position 97-2, "Software Revenue Recognition"
("SOP 97-2"), was issued which provides guidance on applying generally accepted
accounting principles in recognizing revenue on software transactions. SOP 97-2
is effective for transactions entered into in fiscal years beginning after
December 15, 1997. The Company will adopt the guidelines of SOP 97-2 as of
January 1, 1998 and does not expect adoption to have a material impact on the
Company's financial results.

B.   ACQUISITIONS:

     On December 30, 1997, the Company acquired both SQLBench International,
Inc. and ARC - Dr. Ambichl & Dr. Reindl Communication GmbH (formerly named ARC
Dr. Ambichl & Dr. Reindl OEG), privately-held developers of Web-based load
testing technology (hereafter referred to as "SQLBench"). Since the acquisition
of each company was contingent upon both companies being acquired, the
transaction was accounted for as a single business combination using the
purchase method. The combined purchase had an aggregate consideration of
approximately $10.1 million, including transaction costs, and consisted of
approximately $4.4 million in cash paid from the Company's existing cash
balances, $4.4 million in subordinated notes payable and the issuance of 144,000
restricted shares of the Company's common stock with a fair value of $1.0
million. The purchase price was allocated to $1.0 million of completed
technology, which is being amortized over three years, and $9.1 million to
purchased research and development in process. The purchased research and
development in process of $9.1 million had not reached technological
feasibility, had no alternative future use and was valued using expected future

cash flows, discounted for risks and uncertainties related to the target markets
and the completion of the products. Consequently, at the date of acquisition,
the $9.1 million allocated to purchased research and development in process was
recorded as a non-recurring charge.

     Set forth below are unaudited pro forma combined results of operations of
the Company and SQLBench for the years ended December 31, 1997 and 1996 as if
the SQLBench acquisition had been completed at the beginning of each year

indicative of future results of operations or results of operations that would
have been reported for the periods indicated had the acquisition of SQLBench
been completed as of January 1, 1997 or 1996 (amounts in thousands, except per

C.   DEVELOPMENT CONTRACTS AND ROYALTY ARRANGEMENTS:

     In 1991, the Company entered into a development agreement with Lotus
Development Corporation to develop and provide support for certain versions of a
product. The Company in turn subcontracted certain work to a third party to
assist in the development. Development was completed in 1992. The Company earns
royalties on sales of the product developed under this agreement. The Company
also must pay a certain percentage of the royalties received to the third party
who assisted with development. For the years ended December 31, 1997 and 1996,
there were no royalties earned pursuant to this agreement. During the year ended
December 31, 1995, the Company earned $101,000 pursuant to this agreement.

     In addition, the Company participates in other royalty arrangements with
third parties and expenses such amounts as revenues from the related products
are recognized.

     Depreciation and amortization of property and equipment amounted to
$996,000, $591,000, and $258,000 during the years ended December 31, 1997, 1996
and 1995, respectively.

E.   SUBORDINATED NOTES PAYABLE:

     In conjunction with the SQLBench acquisition, the Company issued $4.4
million of subordinated notes payable that bear interest at prime rate (8.5% at
December 31, 1997).

     Subject to certain acceleration terms set forth below, the notes mature on
December 30, 2002. Interest is payable in arrears semi-annually beginning on
June 30, 1998 and on each December 31 and June 30 thereafter. If the holders of
the notes terminate employment with the Company prior to December 30, 2000, no
interest shall accrue with respect to any period following such termination. In
the event that the note holders are either (i) employed by the Company as of the
dates set forth below or (ii) terminated by the Company without cause or by
reason of death or permanent disability, payments under the notes shall be made
according to the following schedule (in thousands):

                          ------
     Total                $4,415 
</TABLE>

     The Company's Convertible Subordinated Notes were converted into 654,200
shares of common stock during the year ended December 31, 1996 at $1.00 per
share.

F.   STOCKHOLDERS' EQUITY:

Common Stock

     In February 1996, the Board of Directors of the Company voted for the
following, which were approved by the stockholders on February 16, 1996: (i) the
reincorporation of the Company from a California corporation to a Delaware
corporation; (ii) an amendment of the Company's Certificate of Incorporation

                                     F-12
<PAGE>

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

to increase the number of authorized shares of common stock and preferred stock
to 30 million and 9 million shares, respectively; (iii) the designation of 4
million shares of such 9 million shares of preferred stock as Series A preferred
stock; (iv) the changing of the per share par value of the common stock and
preferred stock from no par value to $.01 par value; (v) the amendment and
restatement of the Company's 1989 Incentive and Non-Qualified Stock Option Plan,
pursuant to which, among other things, the number of shares of common stock
reserved for issuance pursuant to options granted pursuant to the plan was
increased to 2,450,000 shares, the name of the plan was changed to the 1996
Amended and Restated Incentive and Non-Qualified Stock Option Plan (the "Option
Plan"), and stock option grants to non-employee directors were authorized; and
(vi) the Employee Stock Purchase Plan, which permits eligible employees to
purchase common stock of the Company up to a maximum of 100,000 shares of common
stock.

     In May 1997, the stockholders of the Company approved the increase of
550,000 shares of common stock reserved for issuance pursuant to options granted
pursuant to the Option Plan.

     In April 1996, the Company consummated an initial public offering of
3,162,500 shares of the Company's common stock ($.01 par value) at an initial
public offering price of $18.00 per share. The total shares issued pursuant to
the initial public offering consisted of 2 million shares sold by the Company,
750,000 shares sold by selling shareholders, and an additional 412,500 shares
sold by the Company pursuant to the underwriters' over-allotment option.
Proceeds to the Company, net of underwriters' discount and associated costs of
$858,000, were approximately $39.5 million. Concurrent with the closing of the
offering, all outstanding shares of Series A preferred stock were converted into
common stock.

     In February 1994, the Company sold 500,000 shares of Series A preferred
stock at a purchase price of $2.00 per share and received aggregate proceeds of
$1.0 million in cash. The Company paid $75,000 in related issuance costs. This
transaction included the sale of 375,000 shares of Series A preferred stock and
the issuance of a non-qualified stock option to purchase 125,000 shares of
Series A preferred stock exercisable at $2.00 per share, to an investor who
became a member of the Board of Directors. The option vested over three years
and provided that vesting of the option may be accelerated by the Board of
Directors or upon occurrence of certain events, including a public offering,
merger or liquidation. This option was exercised immediately prior to the
closing of the initial public offering. The Company had also entered into a
consulting agreement with this member of the Board of Directors. The Company
paid no amounts in 1997 or 1996. In 1995, the Company paid a total of $120,000.

     In conjunction with the SQLBench acquisition, the Company issued
approximately 144,000 shares of unregistered restricted stock which by agreement
cannot be sold or otherwise disposed of for two years from the acquisition date.

Stock Compensation Plans

     As of December 31, 1997, the Company has two stock-based compensation plans
(the "Plans"). The Company applies APB 25 in accounting for the Plans. Had
compensation cost for the Company's Plans been determined based on the fair
value at the grant dates for awards under those Plans consistent with the
methodology of SFAS 123, the Company's net income (loss) and income (loss) per
share would have been adjusted to the pro forma amounts indicated below (in
thousands, except per share data):

</TABLE>


     For the years ended December 31, 1997, 1996 and 1995, total compensation
cost recognized in pro forma loss for stock-based employee compensation awards
was $2,123,000, $1,152,000 and $84,000, respectively.

     Since the SFAS 123 method of accounting has not been applied to options
granted prior to January 1, 1995, the resulting compensation cost may not be
representative of that to be expected in future years.

Stock Option Plan

     The Option Plan provides for the grant of common stock options, for which
there were 3 million shares of common stock reserved.

     Incentive stock options (ISOs) may be granted to any officer or employee of
the Company. Nonqualified stock options may be granted to any officer, employee,
consultant, director or other agent of the Company. In the case of ISOs, the
exercise price shall be at least 100% (110% in certain cases) of the fair market
value of the common stock on the date of grant. Options become exercisable at
varying rates, generally over three or four years, as determined by the Board of
Directors.

     Subject to certain exceptions defined under the Option Plan, options expire
10 years from the date of grant. As of December 31, 1997, 1996 and 1995, options
to purchase 877,000, 628,000 and 415,000 shares, respectively, were exercisable
with a weighted average exercise price of $4.88, $2.51 and $1.43 per share,
respectively. 

     The weighted average fair value of the stock options granted during 1997,
1996 and 1995 was $5.78, $7.30 and $.68 per share, respectively. For the
computation in accordance with SFAS 123, the fair value of each stock option
grant is estimated on the date of grant using the Black-Scholes option pricing
model with the following weighted average assumptions used for grants in 1997,
1996 and 1995, respectively: risk-free interest rate of 6.1%, 5.9% and 7.1%;
dividend yield of 0%; expected life of five years; and expected volatility of
60%, 47% and 0%.

     For various price ranges, weighted average information for options
outstanding at December 31, 1997 were as follows:

Employee Stock Purchase Plan

     On February 12, 1996, the Company established the Segue Software, Inc. 1996
Employee Stock Purchase Plan, under which eligible employees may purchase shares
of the Company's common stock through payroll deductions.  The shares can be
purchased for 85% of the lower of the beginning or ending fair market value of
each six-month segment within the offering period. Purchases are limited to 10%
of an employee's annual compensation.  A total of 100,000 shares of the
Company's common stock are reserved for issuance under the stock purchase plan,
of which approximately 37,000 shares have been issued as of December 31, 1997.
No shares had been issued as of December 31, 1996.

     For the computation in accordance with SFAS 123, the fair value of the
employees' purchase rights is estimated using the Black-Scholes model with the
following assumptions for 1997 and 1996: risk-free interest rate of 5.3% and
5.4%; dividend yield of 0%; expected life of six months; and expected volatility
of 60%.

G.   NET INCOME (LOSS) PER SHARE:

     Effective December 31, 1997, the Company adopted Statement of Financial
Accounting Standards No. 128 ("SFAS 128"), "Earnings Per Share". Under the new
standard, primary and fully diluted earnings per share were replaced with basic
and diluted earnings per share. All net income (loss) per common share amounts
have been restated to conform to the requirements of SFAS 128.

     Options to purchase 584,000 weighted average shares of common stock at an
average exercise price of $8.32 per share were outstanding for the year ended
December 31, 1997, but were not included in the calculation of diluted net loss
per common share because their inclusion would have been antidilutive.  Options
to purchase 24,000 weighted average shares of common stock at an average
exercise price of $21.44 were outstanding for the year ended December 31, 1996,
but were not included in the calculation of diluted net income per common share
because the options' exercise prices were greater than the average market price
of the common shares for the period.  Options to purchase 1.2 million weighted
average shares of common stock at an average exercise price of $1.72 per share
were outstanding for the year ended December 31, 1995, but were not included in
the calculation of diluted net loss per common share because their inclusion
would have been antidilutive.

H.   EMPLOYEE SAVINGS PLAN:

     On November 1, 1990, the Company established the Segue Software, Inc.
401(k) Plan, under which all employees may make contributions to their
respective participant accounts. The Company may, at its discretion, make
matching contributions on behalf of its employees. Employees must have completed
two years of service to be eligible for the Company's contributions. No matching
contributions were made during the years ended December 31, 1997, 1996 and 1995.

     The Company had a provision for income taxes of $56,000 and $20,000 in 1997
and 1996, respectively, principally for state taxes. There was no provision for
income taxes in 1995. As of December 31, 1997, the Company had federal net
operating loss carryforwards of approximately $4.5 million and state net
operating loss carryforwards of $1.8 million, of which $3,119,000 relates to
deductions attributable to the exercise of non-qualified stock options and
employees' disposition of stock acquired through incentive stock options, as
well as $821,000 of federal tax credit carryforwards available for income tax
purposes. These carryforwards generally expire in the years 1998 through 2012
and may be subject to annual limitations as a result of changes in the Company's
ownership. Management of the Company has evaluated the positive and negative
evidence impacting the realizability of its deferred tax assets, which are
comprised principally of net operating loss carryforwards and tax credits. Based
on the weight of the available evidence, it is more likely than not that all of
the deferred tax assets will not be realized, and accordingly the deferred tax
assets have been fully reserved. Management re-evaluates the positive and
negative evidence on a quarterly basis.

     The Company leases facilities for its headquarters in Massachusetts under
non-cancelable operating leases that expire in 1998. The Company also leases
certain U.S. and foreign sales offices and certain equipment under various
leases with lease terms ranging from month-to-month up to three years. Certain
of these leases contain renewal options. The agreements generally require the
payment of utilities, real estate taxes, insurance and repairs. Future minimum
payments under the facilities and equipment leases with non-cancelable terms are
as follows as of December 31, 1997 (in thousands):

     Rent expense for the years ended December 31, 1997, 1996 and 1995 amounted
to $680,000, $585,000 and $263,000, respectively.

Royalty Commitments

     In November 1996, the Company entered into an agreement with a vendor who
licensed specific software to the Company for purposes of marketing and
distribution.  Under the terms of the agreement, the Company was required to pay
$1.0 million in royalties by December 31, 1997.  As of December 31, 1996, the
Company had paid $100,000 and recorded a minimum royalty commitment of $900,000.
Royalty expense was recognized based upon the sale of the related product.  As
of December 31, 1997, the Company had paid $800,000 in total and recognized
royalty expense of $170,000 related to the royalty agreement.  In December 1997,
the Company acquired the vendor (see Note B) with the existing royalty agreement
being terminated. The remaining prepaid royalty of $630,000 was refunded to the
Company in conjunction with the acquisition.

K.   NON-RECURRING CHARGES:

     In the fourth quarter of 1997, the Company recognized a charge of $9.1
million related to the write-off of purchased research and development in
process in conjunction with the SQLBench acquisition and $718,000 consisting of
severance and accelerated vesting of options related to the resignation of the
Company's former President and Chief Executive Officer. The charge of $718,000
consisted of $195,000 in severance and $523,000 in accelerated vesting of
options for common stock.

     For the year ended December 31, 1995, severance charges reflect costs
incurred pursuant to an employment separation agreement dated as of June 30,
1995 between the Company and its former Chief Executive Officer.

     On September 30, 1996, the Company entered into a definitive agreement with
a plaintiff, a software company located in Cambridge, MA, to settle litigation
brought against the Company and certain of its current and former employees. The
Company recorded a charge of $744,000 during the third quarter of 1996 to cover
the settlement and other expenses incurred in connection therewith.

M.   SUBSEQUENT EVENT:

     In the second quarter of 1998, the Company expects to enter into a nine
year lease commitment for 40,500 to 67,500 square feet, effective August 1,
1998, at an annual rental rate of approximately $2.2 million. The lease expires

("Buyer"), SGE Merger Corp., a Delaware corporation and a wholly owned
subsidiary of Buyer ("Merger Sub"), SQLBench International, Inc., a Georgia

which include Klaus K. Obermeier and Susan P. Obermeier, (the "Stockholders"
and, together with SQLBench, the "Sellers").


                              W I T N E S S E T H
                              - - - - - - - - - -

     WHEREAS, the SQLBench Stockholders own of record and beneficially all of
the issued and outstanding capital stock of SQLBench, consisting of 10,000
shares of SQLBench's Common Stock, $.10 par value per share (said shares being
referred to herein as the "SQLBench Shares"); and

     WHEREAS, the SQLBench Stockholders desire to sell all of the SQLBench
Shares to Buyer, and Buyer desires to acquire all of the SQLBench Shares
pursuant to a forward triangular merger.

     NOW, THEREFORE, in order to consummate said purchase and sale and in
consideration of the mutual agreements set forth herein, the parties hereto
agree as follows:

hereto shall cause the Certificate of Merger to be filed with the Secretary of

with, Section 14-2-1105 of the Georgia Code and (b) publication of notice of
merger to be made as required by Section 14-2-1105.1 of the Georgia Code.  The
Merger shall be effective as of the date of filing of the Certificate of Merger
(the "Effective Time").

          1.1.4  Certificate of Incorporation.  From and after the Effective 
                 ----------------------------
Time, the Certificate of Incorporation of Merger Sub, as in effect immediately

Incorporation of the Surviving Corporation, and shall thereafter continue in
effect until amended as provided therein and in accordance with the Delaware

          1.1.7  Conversion of Shares.  At the Effective Time, by virtue of the
                 --------------------                                          
Merger, the manner and the basis of converting the shares of capital stock of

the "Shares") shall, by virtue of the Merger and without any action on the part
of the Stockholders or SQLBench, be converted into the right to receive the
following consideration (the "Merger Consideration"):

Amount") divided by 10,000 (the "Per Share Cash Consideration Amount"); and

                      (ii) that fraction of Buyer Common Stock, the numerator of
which equals 143,885 and the denominator of which equals 10,000.  The aggregate

                 (b)  all of the certificates representing the SQLBench Shares,
by virtue of the Merger and without any action on the part of the Stockholders
or SQLBench, shall be deemed to be no longer outstanding, shall not be
transferable on the books of the Surviving Corporation, and shall represent
solely the right to receive the amount determined pursuant to Section 1.1.7(a)
hereof.

          1.1.8  Manner of Payment.  At the Effective Time, Buyer shall (i) pay
                 -----------------

Stockholders, the Note (as defined below) and (iii) deliver to the Stockholders'
Representative for the account of the Stockholders, the Buyer Shares.

     1.2  Promissory Note.  At the Effective Time, Buyer shall execute and

subordinated promissory note of Buyer (the "Note") in a principal amount equal
to $696,200, such Note to be dated the date of the Closing and to be in
substantially the form of Exhibit 1.2 attached hereto.  At such time or times as
                          -----------                                           
any amounts become due and payable under the Note in accordance with the terms
thereof, Buyer shall pay or cause to be paid to the Stockholders'
Representative, as paying agent, in immediately available funds, the amounts
then due and payable under the Note, such amounts so deposited with
Stockholders' Representative to be distributed by the Stockholders'
Representative in the manner provided in, and otherwise to be subject to the
terms of, this Agreement.  At such time as all obligations under the Note are
satisfied in full, the Stockholders' Representative shall deliver to Buyer the
Note marked "CANCELED."

     1.3  Lock-up Agreement.  Each Stockholder agrees not to sell, pledge,
          -----------------                                               
encumber or otherwise transfer or dispose of all or any portion of the Buyer
Shares issued to such Stockholder hereunder during the two (2) year period
following the Closing Date.  Buyer may impose stop-transfer instructions with
respect to the Buyer Shares subject to the foregoing restriction until the end
of such two (2) year period.

     1.4  Stockholders' Representative.
          ---------------------------- 

                 (a)  In order to administer efficiently (i) the implementation
of the Agreement by the Stockholders, (ii) the waiver of any condition to the
obligations of the Stockholders to consummate the transactions contemplated
hereby and (iii) the settlement of any dispute with respect to the Agreement,
the Stockholders hereby designate Mr. Klaus Obermeier as their representative
(the "Stockholders' Representative").

                 (b)  The Stockholders hereby authorize the Stockholders'
Representative (i) to take all action necessary in connection with the
implementation of the Agreement on behalf of the Stockholders, the waiver of any
condition to the obligations of the Stockholders to consummate the transactions
contemplated hereby or the settlement of any dispute, (ii) to give and receive

                                       3
<PAGE>
 
to take any and all additional action as is contemplated to be taken by or on
behalf of the Stockholders by the terms of this Agreement.

                 (c)  In the event that the Stockholders' Representative dies,
becomes legally incapacitated or resigns from such position, Susan P. Obermeier
shall fill such vacancy and shall be deemed to be the Stockholders'
Representative for all purposes of this Agreement; however, no change in the
Stockholders' Representative shall be effective until Buyer is given notice of
it by the Stockholders.

                 (d)  All decisions and actions by the Stockholders'
Representative shall be binding upon all of the Stockholders, and no Stockholder
shall have the right to object, dissent, protest or otherwise contest the same.

                 (e)  By their execution of this Agreement, the Stockholders
agree that:

                      (i)    Buyer shall be able to rely conclusively on the
instructions and decisions of the Stockholders' Representative as to any actions
required or permitted to be taken by the Stockholders or the Stockholders'
Representative hereunder, and no party hereunder shall have any cause of action
against Buyer for any action taken by Buyer in reliance upon the instructions or
decisions of the Stockholders' Representative;

                      (ii)   all actions, decisions and instructions of the
Stockholders' Representative shall be conclusive and binding upon all of the
Stockholders and no Stockholder shall have any cause of action against the
Stockholders' Representative for any action taken, decision made or instruction
given by the Stockholders' Representative under this Agreement, except for fraud
or willful breach of this Agreement by the Stockholders' Representative;

                      (iii)  remedies available at law for any breach of the
provisions of this Section 1.4 are inadequate; therefore, Buyer shall be
entitled to temporary and permanent injunctive relief without the necessity of
proving damages if Buyer brings an action to enforce the provisions of this
Section 1.4; and

                      (iv)   the provisions of this Section 1.4 are independent
and severable, shall constitute an irrevocable power of attorney, coupled with
an interest and surviving death, granted by the Stockholders to the
Stockholders' Representative and shall be binding upon the executors, heirs,
legal representatives and successors of each Stockholder.

                 (f)  All fees and expenses incurred by the Stockholders'
Representative shall be paid by the Stockholders.

     1.5  Closing.  The transactions contemplated by this Agreement shall be

                 (b)  Except as set forth on Schedule 2.8 hereto, SQLBench has
                                             ------------
in accordance with applicable law filed all federal, state, local and foreign
tax returns required to be filed by it through the date hereof, and all such
returns correctly and accurately set forth the amount of any Taxes relating to
the applicable period. A list of all federal, state, local and foreign income
tax returns filed with respect to SQLBench for taxable periods ended on or after
October 22, 1996, are set forth in Schedule 2.8 hereto, and said Schedule
                                   ------------
indicates those returns that have been audited or currently are the subject of
an audit. SQLBench has delivered to Buyer correct and complete copies of all
federal, state, local and foreign income tax returns listed on said Schedule,
and of all examination reports and statements of deficiencies assessed against
or agreed to by SQLBench with respect to said returns. SQLBench is not required
to file a foreign tax return, or to pay any Stockholders' foreign taxes, in
connection with the business conducted by SQLBench.

                 (c)  Neither the Internal Revenue Service nor any other
governmental authority is now asserting or, to the knowledge of the
Stockholders, threatening to assert against SQLBench any deficiency or claim for
additional Taxes. No claim has ever been made by an authority in a jurisdiction
where SQLBench does not file reports and returns that SQLBench is or may be
subject to taxation by that jurisdiction. There are no security interests on any
of the assets of SQLBench that arose in connection with any failure (or alleged
failure) to pay any Taxes. None of the Sellers has entered into a closing
agreement pursuant to Section 7121 of the Internal Revenue Code of 1986, as
amended, (the "Code").

                 (d)  There has not been any audit of any tax return filed by
SQLBench for any tax period, no audit of any tax return of SQLBench is in
progress, and SQLBench has not been notified by any tax authority that any such
audit is contemplated or pending. No extension of time with respect to any date
on which a tax return was or is to be filed by SQLBench is in force, and no
waiver or agreement by SQLBench is in force for the extension of time for the
assessment or payment of any Taxes.

                 (e)  None of the Sellers has been (and has no liability for
unpaid Taxes because it once was) a member of an "affiliated group" (as defined
in Section 1504(a) of the Code). SQLBench has never filed, nor has it been
required to file, a consolidated, combined or unitary tax return with any other
entity. SQLBench does not own, nor has it ever owned, a direct or indirect
interest in any trust, partnership, corporation or other entity, nor is any such
interest necessary to conduct the business of SQLBench, and Buyer is not
acquiring from any Seller an interest in any such entity (except for the capital
stock of SQLBench). No such entity is a party to any tax sharing agreement.

                 (f)  None of the Sellers is a "foreign person" within the
meaning of Section 1445 of the Code and Treasury Regulations Section 1.1445-2.

                 (g)  For purposes of this Agreement, all references to Sections
of the Code shall include any predecessor provisions to such Sections.

          -------------------                                                   
the reserve for bad debts set forth on the Base Balance Sheet) are or will be at

setoff or counterclaim.  SQLBench does not have any accounts or loans receivable

any director, officer or employee of SQLBench, and all accounts and loans
receivable from any such person, firm or corporation shall be paid in cash prior
to the Closing.

          --------------------------                                            
there has not been:

                 (i)   any change in the financial condition, properties,
assets, liabilities, business or operations of SQLBench which change by itself
or in conjunction with all other such changes, has been materially adverse with
respect to SQLBench;

                 (ii)  any contingent liability incurred by SQLBench as
guarantor or otherwise with respect to the obligations of others or any
cancellation of any debt or claim owing to, or waiver of any material right of,
SQLBench;

                 (iii) any mortgage, encumbrance or lien placed on any of the

provided by SQLBench or the conduct of SQLBench's business since the date of the
Base Balance Sheet regardless of whether claims in respect thereof have been
asserted), other than obligations and liabilities incurred in the ordinary
course of business consistent with the terms of this Agreement (it being
understood that product or service liability claims shall not be deemed to be
incurred in the ordinary course of business);

                 (v)   any purchase, sale or other disposition, or any agreement
or other arrangement for the purchase, sale or other disposition, of any of the
properties or assets of SQLBench other than in the ordinary course of business;

                 (vi)  any damage, destruction or loss, whether or not covered
by insurance, materially and adversely affecting the properties, assets or
business of SQLBench;

                 (viii) any agreement or understanding whether in writing or
otherwise, for SQLBench to take any of the actions specified in paragraphs (i)

     2.11 Ordinary Course.  Since the date of the Base Balance Sheet, SQLBench
          ---------------                                                     
has conducted its business and operations only in the ordinary course and

the assets identified on Schedule 2.11 hereto outside of the ordinary course of
                         -------------

reflected in the Base Balance Sheet.  Buyer and Merger Sub consent to such
transfer.

     2.12 Banking Relations.  All of the arrangements which SQLBench has with
          -----------------

                                                                   -------------
hereto, indicating with respect to each of such arrangements the type of
arrangement maintained (such as checking account, borrowing arrangements, safe
deposit box, etc.) and the person or persons authorized in respect thereof.

     2.13 Intellectual Property.
          --------------------- 

                 (a)  Except as set forth in the License and Distribution
Agreement between SQLBench and ARC - Dr. Ambichl & Dr. Reindl Communication GmbH
dated November 1, 1996, SQLBench owns no right, title or interest in or to any
patents, copyrights, technology, software, software tools, know-how, processes,
trade secrets, trademarks, service marks, trade names and other technology or
proprietary rights developed or discovered in connection with or contained in
the SQLBench and SQLBench.web products (the "SQLBench Products"). Except as set
forth in Schedule 2.13, SQLBench owns all right, title and interest in and to
all patents, copyrights, technology, software, software tools, know-how,
processes, trade secrets, trademarks, service marks, trade names and other
proprietary rights used in or necessary for the conduct of SQLBench's business
as conducted to the date hereof or contemplated, free and clear of all liens,
claims and encumbrances (including without limitation distribution rights) (all
of which are referred to as "Proprietary Rights"). The foregoing representation
as it relates to Third Party Technology (as hereinafter defined) is limited to
SQLBench's interest pursuant to the Third Party Licenses (as hereinafter
defined), all of which are valid and enforceable and in full force and effect
and which grant SQLBench such right to Third Party Technology as are employed in
or necessary to the business of SQLBench as conducted or proposed to be
conducted prior to the Closing Date.

          (b) Schedule 2.13 hereto contains an accurate and complete description
              -------------                                                     
of (i) all patents, trademarks (with separate listings of registered and
unregistered trademarks), trade names, and registered and unregistered
copyrights in or related to the SQLBench Products owned by SQLBench, all
applications and registration statements therefor, and a list of all licenses
and other agreements relating thereto, and (ii) a list of all licenses and other
agreements with third parties (the "Third Party Licenses") relating to any
software, technology, know-how, or processes that SQLBench is licensed or
otherwise authorized by

                                       11
<PAGE>
 
such third parties to use, market, distribute or incorporate into products
distributed by SQLBench (such software, technology, know-how and processes are
collectively referred to as the "Third Party Technology"). All of SQLBench's
trademark or trade name registrations related to the SQLBench Products and all
of SQLBench's copyrights in any of the SQLBench Products are valid and in full
force and effect; and consummation of the transactions contemplate hereby will
not alter or impair any such rights. There is no material default by any party
to any Third Party License and all of SQLBench's rights thereunder are freely
assignable. To the knowledge of the Sellers, the licensors under such Third
Party Licenses have and had all requisite power and authority to grant the
rights purported to be conferred thereby. True and complete copies of such Third
Party Licenses, and any amendments thereto, have been provided to Buyer.

                 (c)  No claims have been asserted against SQLBench or any of
the Stockholders (and neither SQLBench nor any of the Stockholders is aware of
any claims which are likely to be asserted against SQLBench or any of the
Stockholders or which have been asserted against others) by any person
challenging SQLBench's use or distribution of any patents, trademarks, trade
names, copyrights, trade secrets, software, technology, know-how or processes
utilized by SQLBench (including, without limitation, the Third Party Technology)
or challenging or questioning the validity or effectiveness of any license or
agreement relating thereto (including, without limitation, the Third Party
Licenses). To the Sellers' knowledge, there is no valid basis for any claim of
the type specified in the immediately preceding sentence which could in any way
relate to or interfere with the continued enhancement and exploitation by
SQLBench of any of the SQLBench Products. None of the SQLBench Products nor the
use of any patents, trademarks, trade names, copyrights, software, technology,
know-how or processes by SQLBench in its current business infringes on the
rights of, constitutes misappropriation of, or in any way involves unfair
competition with respect to, any proprietary information or intangible property
right of any third person or entity, including without limitation any trade
secret, copyright, trademark or trade name, or, to the knowledge of the Sellers,
any patent.

                 (d)  All licenses or other agreements pursuant to which the
Sellers have granted rights to others in Proprietary Rights owned or licensed by
the Sellers are listed on Schedule 2.13. All of such licenses or agreements are
in full force and effect, there is no default by any party thereto and all of
Sellers' rights thereunder are freely assignable. True and complete copies of
all such licenses or other agreements, and any amendments thereto, have been
provided to Buyer. Except as set forth in Schedule 2.13, the Sellers have not
granted any third party any right to manufacture, reproduce, distribute, market
or exploit any of the SQLBench Products or any adaptations, translations, or
derivative works based on the SQLBench Products or any portion thereof,
including, without limitation, as a value added reseller. Except with respect to
the rights of third parties to the Third Party Technology, no third party has
any right to manufacture, reproduce, distribute, market or exploit any
underlying works or materials of which any of the SQLBench Products are a
"derivative work" as that term is defined in the United States Copyright Act,
Title 17, U.S.C. Section 101.

                 (e)  Except as set forth on Schedule 2.13, no designs,
                                             ------------- 
drawings, specifications, source code, object code, documentation, flow charts
or diagrams incorporating, embodying or reflecting any of the SQLBench Products
at any stage of their development (the "SQLBench Components") were written,
developed and created in whole or in part by any employee of SQLBench with or
without the assistance of any third party or entity or were created by third
parties (including, without limitation, each of the Stockholders), who assigned
ownership of their rights to SQLBench in any manner. The Sellers have at all
times used commercially reasonable efforts to treat the SQLBench Products and
the SQLBench Components as containing trade secrets and have not disclosed or
otherwise dealt with such items in such a manner as to cause the loss of such
trade secrets by release into the public domain.

                 (f)  To the Sellers' knowledge, no employee of SQLBench is in
violation of any term of any employment contract, patent disclosure agreement or
any other contract or agreement relating to the relationship of any such
employee with SQLBench or, to the best of the Sellers' knowledge, any other
party, including, without limitation, any previous employer, because of the
nature of the business conducted by SQLBench or proposed to be conducted by
SQLBench.

                 (g)  Each person presently or previously employed by SQLBench
(including independent contractors, if any) employed in a research and
development or other technical position has executed a confidentiality and non-
disclosure agreement previously provided to Purchaser or its representatives.
Such confidentiality and non-disclosure agreements constitute valid and binding
obligations of SQLBench and such person, enforceable in accordance with their
respective terms. To the best of SQLBench's and each of the Stockholder's
knowledge, neither the execution or delivery of such agreements, nor the
carrying on of SQLBench's business as employees by such persons, nor the conduct
of SQLBench's business as currently anticipated, will conflict with or result in
a breach of the terms, conditions or provisions of or constitute a default under
any contract, covenant or instrument under which any of such persons is
obligated.  SQLBench is not making unauthorized use of any confidential
information or trade secrets of any person, including, without limitation, any
former employer or any past or present employee of SQLBench. Neither SQLBench
nor, to the knowledge of the Sellers, any of SQLBench's employees have any
agreements or arrangements with any persons other than SQLBench related to
confidential information  or trade secrets of such persons or restricting any
such employee's ability to engage in business activities of any nature.

                 (h)  No product liability or warranty claims which individually
or in the aggregate could exceed Five Thousand Dollars ($5,000) have been
communicated to or threatened against SQLBench nor, to the best of the Sellers'
knowledge, is there any specific situation, set of facts or occurrence that
provides a basis for such claim. SQLBench has provided to Buyer an accurate list
of all errors or "bugs" in the SQLBench Products which are contained in the

2.8 hereto, and said Schedule indicates those returns that have been audited or
- ---
currently are the subject of an audit. ARC has delivered to Buyer correct and
complete copies of all federal, state, local and foreign income tax returns
listed on said Schedule, and of all examination reports and statements of
deficiencies assessed against or agreed to by ARC with respect to said returns.

                 (c)    Neither the Internal Revenue Service nor any other
governmental authority is now asserting or, to the knowledge of the Sellers,
threatening to assert against ARC any deficiency or claim for additional Taxes.
No claim has ever been made by an authority in a jurisdiction where ARC does not
file reports and returns that ARC is or may be subject to taxation by that
jurisdiction. There are no security interests on any of the assets of ARC that
arose in connection with any failure (or alleged failure) to pay any Taxes.

                 (d)    No extension of time with respect to any date on which a
tax return was or is to be filed by ARC is in force, and no waiver or agreement
by ARC is in force for the extension of time for the assessment or payment of
any Taxes.

                 (e)    None of the Sellers has been (and has no liability for
unpaid Taxes because it once was) a member of an "affiliated group." ARC has
never filed, nor has it been required to file, a consolidated, combined or
unitary tax return with any other entity. ARC does not own, nor has it ever
owned, a direct or indirect interest in any trust, partnership, corporation or
other entity, nor is any such interest necessary to conduct the business of ARC,
and Buyer is not acquiring from any Seller an interest in any such entity. No
such entity is a party to any tax sharing agreement.

                 (f)    ARC has made all necessary and required contributions
under applicable social security systems with respect to employees of ARC and
non-employee contractors of ARC.

     2.9  Accounts Receivable.  All of the accounts receivable of ARC (less the
          -------------------                                                  
reserve for bad debts set forth on the Base Balance Sheet) are or will be at the
Closing valid and enforceable claims, fully collectible and subject to no setoff
or counterclaim.  ARC does not have any accounts or loans receivable from any
person, firm or corporation which is affiliated with either ARC or from any
director, officer or employee of ARC, and all accounts and loans receivable from
any such person, firm or corporation shall be paid in cash prior to the Closing.

     2.10 Absence of Certain Changes.  Other than the conversion of ARC from an
          --------------------------                                           
OEG to a GmbH, since the date of the Base Balance Sheet, there has not been:

                        (i)   any change in the financial condition, properties,
assets, liabilities, business or operations of ARC which change by itself or in
conjunction with all other such changes, has been materially adverse with
respect to ARC;

                        (ii)  any contingent liability incurred by ARC as
guarantor or otherwise with respect to the obligations of others or any
cancellation of any debt or claim owing to, or waiver of any material right of,
ARC;

                        (iii) any mortgage, encumbrance or lien placed on any of
the assets or properties of ARC which remain in existence on the date hereof or
will remain on the Closing Date;

                        (iv)  any obligation or liability of any nature incurred
by ARC whether accrued, absolute, contingent or otherwise, asserted or
unasserted (including without limitation liabilities for Taxes due or to become
due or contingent or potential liabilities relating to products or services
provided by ARC or the conduct of ARC's business since the date of the Base
Balance Sheet regardless of whether claims in respect thereof have been
asserted), other than obligations and liabilities incurred in the ordinary
course of business consistent with the terms of this Agreement (it being
understood that product or service liability claims shall not be deemed to be
incurred in the ordinary course of business);

<PAGE>
 
                        (v)    any purchase, sale or other disposition, or any
agreement or other arrangement for the purchase, sale or other disposition, of
any of the properties or assets of ARC other than in the ordinary course of
business;

                        (vi)   any damage, destruction or loss, whether or not
covered by insurance, materially and adversely affecting the properties, assets
or business of ARC;

                        (vii)  any other transaction entered into by ARC other
than transactions in the ordinary course of business; or

                        (viii) any agreement or understanding whether in writing
or otherwise, for ARC to take any of the actions specified in paragraphs (i)
through (viii) above.

     2.11 Ordinary Course.  Other than the conversion of ARC from an OEG to a
          ---------------                                                    
GmbH, since the date of the Base Balance Sheet, ARC has conducted its business
and operations only in the ordinary course and consistently with its prior
practices.

     2.12 Banking Relations.  All of the arrangements which ARC has with any
          -----------------

                                                               -------------
hereto, indicating with respect to each of such arrangements the type of
arrangement maintained (such as checking account, borrowing arrangements, safe
deposit box, etc.) and the person or persons authorized in respect thereof.

     2.13 Proprietary Rights.
          ------------------ 

                 (a)    Except as set forth in Schedule 2.13, ARC owns all
right, title and interest in and to all patents, copyrights, technology,
software, software tools, know-how, processes, trade secrets, trademarks,
service marks, trade names and other proprietary rights used in or necessary for
the conduct of ARC's business as conducted to the date hereof or contemplated,
including, without limitation, the technology and all proprietary rights
developed or discovered in connection with or contained in ARC's products (the
"ARC Products"), free and clear of all liens, claims and encumbrances (including
without limitation distribution rights) (all of which are referred to as
"Proprietary Rights"). The foregoing representation as it relates to Third Party
Technology (as hereinafter defined) is limited to ARC's interest pursuant to the
Third Party Licenses (as hereinafter defined), all of which are valid and
enforceable and in full force and effect and which grant ARC such right to Third
Party Technology as are employed in or necessary to the business of ARC as
conducted or proposed to be conducted prior to the Closing Date.

                 (b)    Schedule 2.13 hereto contains an accurate and complete
                        -------------
description of (i) all patents, trademarks (with separate listings of registered
and unregistered trademarks), trade names, and registered and unregistered
copyrights in or related to the ARC Products, all applications and registration
statements therefor, and a list of all licenses and other agreements relating
thereto, and (ii) a list of all licenses and other agreements with third

                                       13
<PAGE>
 
parties (the "Third Party Licenses") relating to any software, technology, know-
how, or processes that ARC is licensed or otherwise authorized by such third
parties to use, market, distribute or incorporate into products distributed by
ARC (such software, technology, know-how and processes are collectively referred
to as the "Third Party Technology"). All of ARC's trademark or trade name
registrations related to the ARC Products and all of ARC's copyrights in any of
the ARC Products are valid and in full force and effect; and consummation of the
transactions contemplate hereby will not alter or impair any such rights. There
is no material default by any party to any Third Party License and all of ARC's
rights thereunder are freely assignable. To the knowledge of the Sellers, the
licensors under such Third Party Licenses have and had all requisite power and
authority to grant the rights purported to be conferred thereby. True and
complete copies of such Third Party Licenses, and any amendments thereto, have
been provided to Buyer.

                 (c)    No claims have been asserted against ARC or any of the
Stockholders (and neither ARC nor any of the Stockholders is aware of any claims
which are likely to be asserted against ARC or any of the Stockholders or which
have been asserted against others) by any person challenging ARC's use or
distribution of any patents, trademarks, trade names, copyrights, trade secrets,
software, technology, know-how or processes utilized by ARC (including, without
limitation, the Third Party Technology) or challenging or questioning the
validity or effectiveness of any license or agreement relating thereto
(including, without limitation, the Third Party Licenses). To the Sellers'
knowledge, there is no valid basis for any claim of the type specified in the
immediately preceding sentence which could in any way relate to or interfere
with the continued enhancement and exploitation by ARC of any of the ARC
Products. None of the ARC Products nor the use of any patents, trademarks, trade
names, copyrights, software, technology, know-how or processes by ARC in its
current business infringes on the rights of, constitutes misappropriation of, or
in any way involves unfair competition with respect to, any proprietary
information or intangible property right of any third person or entity,
including without limitation any trade secret, copyright, trademark or trade
name, or, to the knowledge of the Sellers, any patent.

                 (d)    All licenses or other agreements pursuant to which the
Sellers have granted rights to others in Proprietary Rights owned or licensed by
the Sellers are listed on Schedule 2.13. All of such licenses or agreements are
in full force and effect, there is no default by any party thereto and all of
Sellers' rights thereunder are freely assignable. True and complete copies of
all such licenses or other agreements, and any amendments thereto, have been
provided to Buyer.  Except as set forth in Schedule 2.13, the Sellers have not
                                           -------------                      
granted any third party any right to manufacture, reproduce, distribute, market
or exploit any of the ARC Products or any adaptations, translations, or
derivative works based on the ARC Products or any portion thereof, including,
without limitation, as a value added reseller. Except with respect to the rights
of third parties to the Third Party Technology, no third party has any right to
manufacture, reproduce, distribute, market or exploit any underlying works or
materials of which any of the ARC Products are a "derivative work" as that term
is defined in the United States Copyright Act, Title 17, U.S.C. Section 101.

                 (e)    Except as set forth on Schedule 2.13, all designs,
                                               ------------- 
drawings, specifications, source code, object code, documentation, flow charts
and diagrams incorporating, embodying or reflecting any of the ARC Products at
any stage of their development (the "ARC Components") were written, developed
and created solely and exclusively by employees of ARC without the assistance of
any third party or entity or were created by third parties (including, without
limitation, each of the Stockholders), who assigned ownership of their rights to
ARC in valid and enforceable consultant confidentiality and invention assignment
agreements. All such employees and third parties have executed waivers of any
right, title or interest in the ARC Products and ARC Components pursuant to
documents prepared by Buyer's counsel. The Sellers have at all times used
commercially reasonable efforts to treat the ARC Products and the ARC Components
as containing trade secrets and has not disclosed or otherwise dealt with such
items in such a manner as to cause the loss of such trade secrets by release
into the public domain.

                 (f)    To the Sellers' knowledge, no employee of ARC is in
violation of any term of any employment contract, patent disclosure agreement or
any other contract or agreement relating to the relationship of any such
employee with ARC or, to the best of the Sellers' knowledge, any other party,
including, without limitation, any previous employer, because of the nature of
the business conducted by ARC or proposed to be conducted by ARC.

                 (g)    Each person presently or previously employed by ARC
(including independent contractors, if any) employed in a research and
development or other technical position has executed a confidentiality and non-
disclosure agreement previously provided to Purchaser or its representatives.
Such confidentiality and non-disclosure agreements constitute valid and binding
obligations of ARC and such person, enforceable in accordance with their
respective terms. To the best of ARC's and each of the Stockholder's knowledge,
neither the execution or delivery of such agreements, nor the carrying on of
ARC's business as employees by such persons, nor the conduct of ARC's business
as currently anticipated, will conflict with or result in a breach of the terms,
conditions or provisions of or constitute a default under any contract, covenant
or instrument under which any of such persons is obligated. ARC is not making
unauthorized use of any confidential information or trade secrets of any person,
including, without limitation, any former employer or any past or present
employee of ARC. Neither ARC nor, to the knowledge of the Sellers, any of ARC's
employees have any agreements or arrangements with any persons other than ARC
related to confidential information or trade secrets of such persons or
restricting any such employee's ability to engage in business activities of any
nature.

                 (h)    No product liability or warranty claims which
individually or in the aggregate could exceed Five Thousand Dollars ($5,000)
have been communicated to or threatened against ARC nor, to the best of the
Sellers' knowledge, is there any specific situation, set of facts or occurrence
that provides a basis for such claim. ARC has provided to Buyer an accurate list
of all errors or "bugs" in the ARC Products which are contained in the computer
databases which ARC maintains for the purpose of tracking errors and "bugs" in
its software. Such list is set forth as Schedule 2.13 (h).

                 (i)    Prior to the date hereof, the Stockholders transferred
all rights, title and interest of the Stockholders in the ARC Products to ARC,
and the Stockholders have no rights, title or interest in the ARC Products.

     2.14 Contracts.  Except for contracts, commitments, plans, agreements and
          ---------

                        (iv)   any other contracts or agreements creating any
obligations of ARC of $5,000 or more per annum with respect to any such contract
or agreement not specifically disclosed elsewhere in this Agreement;

                        (v)    any contract or agreement providing for the
purchase of all or substantially all of its requirements of a particular product
from a supplier;

                        (vi)   any contract or agreement which by its terms does
not terminate or is not terminable without penalty by such entity or any

                        (vii)  any contract not made in the ordinary course of
business;

                        (viii) any contract or agreement for the purchase of any
fixed asset for a price in excess of $5,000 whether or not such purchase is in
the ordinary course of business;

                        (ix)   no agreements, contracts or commitments that
provide for the sale, licensing or distribution by ARC of any of its products,
technology, know-how, trademarks or trade names. Section 2.14 hereof sets forth
                                                 ------------                  
all of the maintenance obligations of ARC without regard to the dollar amount of
such obligation;

                        (x)    any contract containing covenants limiting the
freedom of such entity to compete in any line of business or with any person or
entity;

                        (xi)   any license agreement (as licensor or licensee);

                        (xii)  any indenture, mortgage, promissory note, loan
agreement, guaranty or other agreement or commitment for the borrowing of money;
or

                        (xiii) any contract or agreement with any officer,
employee, director or stockholder of ARC or with any persons or organizations
controlled by or affiliated with any of them.

ARC is not in default under any such contracts, commitments, plans, agreements
or licenses described in said Schedule, and none of the Sellers have any
knowledge of conditions or facts which with notice or passage of time, or both,
would constitute a default.

     Without limiting the provisions of Section 2.13, except for the License and
Distribution Agreement between ARC and SQLBench International, Inc., ARC has not
granted to any third party (including, without limitation, OEMs and site license
customers) any rights to reproduce or manufacture any of the ARC Products, nor
has ARC granted to any third party any exclusive rights of any kind with respect
to any of the ARC Products, including, without limitation, territorial
exclusivity or exclusivity with respect to particular versions, implementations
or translations of any of the ARC Products, nor has ARC granted any third party
any right to market any of the ARC Products under any "private label"
arrangements pursuant to which ARC is not identified as the source of such
goods.

     2.15 Litigation.  There is no litigation or governmental or administrative
          ----------

covenants and obligations herein or in any schedule, exhibit, certificate or
financial statement delivered by any party to the other party incident to the
transactions contemplated hereby are material, shall be deemed to have been
relied upon by the other party and shall survive the Closing regardless of any

any breach of this Agreement or any document or instrument related hereto or in
any Schedule, exhibit or certificate delivered pursuant hereto.

                 (b)    Subject to Section 9.1(c) below, any breach by the

incurred by or made against the Buyer as a result of such breach and then to
collect the balance, if any, directly from the Sellers.

                 (c)    Notwithstanding the foregoing, the Sellers shall not
have any liability to Buyer for any breach of or noncompliance with this
Agreement (and with any other document executed by any of the Sellers in
connection herewith), including by way of set off from any future payments that
Buyer is required to make pursuant to the Note, unless (a) the aggregate amount
of all Losses shall exceed $25,000, and thereafter, Sellers shall only be liable
for Losses in excess of said $25,000; and (b) such claim, except claims with
respect to Section 2.8 or Section 2.13 which may be asserted until the
expiration of the applicable statue of limitations, is asserted against the
Sellers (whether or not such Losses have actually been incurred) on or before
the third anniversary of the Closing Date. Buyer agrees to reasonably cooperate
to minimize Losses.

                 (d)    Notwithstanding the foregoing, Buyer shall not have any
liability to any Seller for breach of or noncompliance with this Agreement or
with any other document executed by Buyer in connection herewith except the Note
or the Employment Agreements, unless and until (a) the aggregate amount of all
Losses shall exceed $25,000, in which case, Buyer shall thereafter only be
liable for Losses in excess of said $25,000; and (b) such claim is asserted
against Buyer (whether or not such Losses have been actually incurred) on or

                     SPECIAL TERMINATION AND VESTING PLAN
                     ------------------------------------


     1.   Executives Covered.  This Special Termination and Vesting Plan (the
          ------------------                                                 
"Plan") shall apply to all executive employees with the title of President,
Chief Executive Officer, Chief Financial Officer, Chief Technical Officer,
Senior Vice President and Executive Vice President (each, a "Covered Executive;"
collectively, the "Covered Executives") of Segue Software, Inc. (the "Company")
or any of its subsidiaries or affiliates.

     2.   Certain Definitions.  For purposes of this Plan, the following terms
          -------------------                                                 
shall have the following meanings:

          (a)  Change in Control.  A "Change in Control" shall mean the
               -----------------                                       
     occurrence of any one of the following events:

               (i)    any "person," as such term is used in Sections 13(d) and
          14(d) of the Securities Exchange Act of 1934 (the "Act") (other than
          the Company, any of its subsidiaries, any trustee, fiduciary or other
          person or entity holding securities under any employee benefit plan or
          trust of the Company, or any of its subsidiaries), together with all
          "affiliates" and "associates" (as such terms are defined in Rule 12b-2
          under the Act) of such person, shall become the "beneficial owner" (as
          such term is defined in Rule 13d-3 under the Act), directly or
          indirectly, of securities of the Company representing 50% or more of
          the then outstanding shares of Common Stock of the Company (the
          "Stock") (other than as a result of an acquisition of securities
          directly from the Company); or

               (ii)   persons who, as of the date hereof, constitute the
          Company's Board of Directors (the "Incumbent Directors") cease for any
          reason, including, without limitation, as a result of a tender offer,
          proxy contest, merger or similar transaction, to constitute at least a
          majority of the Board, provided that any person becoming a director of
          the Company subsequent to the date hereof whose election or nomination
          for election was approved by a vote of at least a majority of the
          Incumbent Directors shall, for purposes of this Plan, be considered an
          Incumbent Director; or

               (iii)  the stockholders of the Company shall approve (A) any
          consolidation or merger of the Company or any subsidiary of the
          Company where the shareholders of the Company, immediately prior to
          the consolidation or merger, would not, immediately after the
          consolidation or merger, beneficially own (as such term is defined in
          Rule 13d-3 under the Act), directly or indirectly, shares representing
          in the aggregate 50% of the voting shares of the corporation issuing
          cash or securities in the consolidation or merger (or of its ultimate
          parent corporation, if any), (B) any sale, lease, exchange or other
<PAGE>
 
          transfer (in one transaction or a series of transactions contemplated
          or arranged by any party as a single plan) of all or substantially all
          of the assets of the Company or (C) any plan or proposal for the
          liquidation or dissolution of the Company.

          Notwithstanding the foregoing, a "Change in Control" shall not be
     deemed to have occurred for purposes of the foregoing clause (i) solely as
     the result of an acquisition of securities by the Company which, by
     reducing the number of shares of Stock outstanding, increases the
     proportionate number of shares of Stock beneficially owned by any person to
     50% or more of the shares of Stock then outstanding; provided, however,
                                                          --------  ------- 
     that if any such person shall thereafter become the beneficial owner of any
     additional shares of Stock (other than pursuant to a share split, stock
     dividend, or similar transaction), then a "Change in Control" shall be
     deemed to have occurred for purposes of the foregoing clause (i).

          (b)  Terminating Event.  A "Terminating Event" shall mean any of the
               -----------------                                              
     following events:

               (i)  termination by the Company of the employment of the Covered
          Executive with the Company for any reason other than for Cause or the
          death of the Covered Executive.  "Cause" shall mean, and shall be
          limited to, the occurrence of any one or more of the following events:

                    (A) a willful act of dishonesty by the Covered Executive
               with respect to any matter involving the Company or any
               subsidiary or affiliate; or

                    (B) conviction of the Covered Executive of a crime involving
               moral turpitude; or

                    (C) the deliberate or willful failure by the Covered
               Executive (other than by reason of the Covered Executive's
               physical or mental illness, incapacity or disability) to
               substantially perform the Covered Executive's duties with the
               Company and the continuation of such failure for a period of 30
               days after delivery by the Company to the Covered Executive of
               written notice specifying the scope and nature of such failure
               and its intention to terminate the Covered Executive for Cause.

               A Terminating Event shall not be deemed to have occurred pursuant
          to this Section 2(b)(i) solely as a result of the Covered Executive
          being an employee of any direct or indirect successor to the business
          or assets of the Company, rather than continuing as an employee of the
          Company following a Change in Control.  For purposes of clauses (A)
          and (C) of this Section 2(b)(i), no act, or failure to act, on the
          Covered Executive's part shall be deemed

                                       2
<PAGE>
 
          "willful" unless done, or omitted to be done, by the Covered Executive
          without reasonable belief that the Covered Executive's act, or failure
          to act, was in the best interest of the Company and its subsidiaries
          and affiliates; or

               (ii) termination by the Covered Executive of the Covered
          Executive's employment with the Company for Good Reason.  "Good
          Reason" shall mean the occurrence of any of the following events:

                    (A) a substantial adverse change, not consented to by the
               Covered Executive, in the nature or scope of the Covered
               Executive's responsibilities, authorities, powers, functions, or
               duties from the responsibilities, authorities, powers, functions,
               or duties exercised by the Covered Executive immediately prior to
               the Change in Control; or

                    (B) a reduction in the Covered Executive's annual base
               salary as in effect on the date of adoption of this Plan or as
               the same may be increased from time to time except for across-
               the-board salary reductions similarly affecting all or
               substantially all management employees; or

                    (C) the relocation of the Company's offices at which the
               Covered Executive is principally employed immediately prior to
               the date of a Change in Control to a location more than fifty
               (50) miles from such offices, or the requirement by the Company
               for the Covered Executive to be based anywhere other than the
               Company's offices at such location, except for required travel on
               the Company's business to an extent substantially consistent with
               the Covered Executive's business travel obligations immediately
               prior to the Change in Control; or

                    (D) the failure by the Company to pay to the Covered
               Executive any portion of his compensation or to pay to the
               Covered Executive any portion of an installment of deferred
               compensation under any deferred compensation program of the
               Company within fifteen (15) days of the date such compensation is
               due without prior written consent of the Covered Executive; or

                    (E) the failure by the Company to obtain an effective
               agreement from any successor to assume and agree to perform this
               Agreement.

     Any termination by the Covered Executive of such Covered Executive's
employment with the Company for any reason other than Good Reason shall not be
deemed to be a Terminating Event hereunder.

     3.   Special Termination Benefits.  Subject to the provisions of Section 4
          ----------------------------                                         
below, in the event that a Terminating Event occurs with respect to a Covered
Executive within one (1) year after a Change in Control, such Covered Executive
shall be provided with the following Special Termination Benefits:

          (a) the Company shall pay to the Covered Executive an amount equal to
     the base salary received by the Covered Executive in the calendar year
     immediately prior to the Change in Control, determined prior to any
     reductions for pre-tax contributions to a cash or deferred arrangement or a
     cafeteria plan.  Said amount shall be paid in periodic installments in
     accordance with the Company's usual practice for its senior executives;

          (b) the Company shall continue to provide health, dental, long-term
     disability, and life insurance benefits to the Covered Executive, on the
     same terms and conditions as though the Covered Executive had remained an
     active employee, for a period of twelve (12) months; and

          (c) the Company shall provide COBRA benefits to the Covered Executive
     following the end of the period referred to in Section 3(b) above, such
     benefits to be determined as though employment had terminated at the end of
     such period.

     4.   Adjustments in Special Termination Benefits.  The Special Termination
          -------------------------------------------                          
Benefits payable pursuant to Section 3 above shall be adjusted as follows:

          (a) All payments shall be reduced by the amount of any severance pay
     benefits payable to any officer under any employment, change in control or
     special termination agreement or severance pay benefits or notice pay to
     any employee under any "tin parachute," WARN, or similar law.

          (b) In the event that the Special Termination Benefits payable to any
     Covered Executive pursuant to this Plan, together with any payments to or
     for the benefit of the Covered Executive under any other agreement or plan
     pursuant to which the Covered Executive is entitled to receive payments or
     benefits, in the aggregate exceeds the amount that may be deducted by the
     entity making the payment by reason of the operation of Section 280G of the
     Internal Revenue Code of 1986, as amended, the amount of the Special
     Termination Benefits shall be reduced to the maximum which may be deducted
     by such entity.

          (c) All payments will be subject to usual and customary tax
     withholding.

          (d) Notwithstanding anything to the contrary contained herein, the
Special Termination Benefits payable pursuant to Section 3 above shall be
subject to the Covered Executive's continued compliance with any non-compete,
confidentiality or other obligations of such Covered Executive pursuant to any
written agreement between the Company and the Covered Executive.

     5.   Vesting of Options.  In the event that a Terminating Event occurs with
          ------------------                                                    
respect to a Covered Executive within one (1) year after a Change in Control,
notwithstanding anything to the contrary contained in the Company's Amended and
Restated Incentive and Non-qualified Stock Option Plan (as amended from time to
time, the "Option Plan"), any option agreement granted under the Option Plan or
any other agreement between the Company and a Covered Executive pursuant to
which options to purchase shares of Stock of the Company have been or are
granted (including, without limitation, the definition of "cause" contained
therein), upon such Terminating Event, all outstanding options held by such
Covered Executive, whether or not previously exercisable by such Covered
Executive, shall become exercisable by the Covered Executive.

     6.   Enforceability.  If any portion or provision of this Plan shall to any
          --------------                                                        
extent be declared illegal or unenforceable by a court of competent
jurisdiction, then the remainder of this Plan, or the application of such
portion or provision in circumstances other than those as to which it is so
declared illegal or unenforceable, shall not be affected thereby, and each
portion and provision of this Plan shall be valid and enforceable to the fullest
extent permitted by law.

     7.   Effect on Other Plans.  Nothing in this Plan shall be construed to
          ---------------------                                             
limit the rights of the Covered Executive under the Company's benefit plans,
programs or policies except as otherwise provided in Section 3 hereof, and
except that the Covered Executive shall have no rights to any severance benefits
under any severance pay plan.

     8.   Obligations of Successors.  In addition to any obligations imposed by
          -------------------------                                            
law upon any successor to the Company, the Company will use its best efforts to
require any successor (whether direct or indirect, by purchase, merger,
consolidation or otherwise) to all or substantially all of the business or
assets of the Company to expressly assume and agree to perform this Plan in the
same manner and to the same extent that the Company would be required to perform
if no such succession had taken place.

     9.   Amendment or Termination of Plan.  The Company may amend or terminate
          --------------------------------                                     
this Plan at any time or from time to time; provided, however, that no such
                                            --------  -------              
amendment or termination shall, without the written consent of the Covered
Executives, in any material adverse way affect the rights of a Covered Executive
with respect to benefits earned prior to the date of amendment or termination.

     10.  No Contract for Continuing Services.  This Plan shall not be construed
          -----------------------------------                                   
as creating any contract for continued services between the Company and any
Covered Executive and nothing herein contained shall give any Covered Executive
the right to be retained as an employee of the Company.

     11.  Governing Law.  This Plan shall be construed, administered, and
          -------------                                                  
enforced in accordance with the laws of the Commonwealth of Massachusetts.

                                                               December 11, 1997


BY HAND
- -------

Ms. Elisabeth Elterman
66 Brookline Street
Newton, MA 02167

Dear Elisabeth:

     This letter will confirm the agreement that we have reached regarding your 
resignation. The purpose of this agreement is to establish an amicable 
arrangement for ending our relationship, to release Segue Software, Inc. (the 
"Company") from any liability to you and to permit you to receive fair and 
reasonable separation pay and related benefits.

     With that understanding, you and the Company agree as follows:

     1.    Resignation
           -----------

     You have resigned from your employment, your office of President and your 
directorship with the Company effective December 31, 1997 ("your resignation 
date").

     2.    Severance Pay
           -------------

     During the period January 1, 1998 through December 31, 1998, the Company 
will pay you $180,000 as severance, payable in twenty-four equal payments of 
$7,500 each, less applicable withholdings and deductions, on the Company's 
regular bi-weekly paydays.

     3.    Benefits
           --------

     You may continue your participation in the Company's group family medical 
and family dental plans for the 18-month period following your resignation date 
pursuant to the provisions of COBRA.  The Company will pay your premium expenses
with respect to the group medical and dental plans until the earlier of December
31, 1998 or the date on which you otherwise become employed; thereafter, your 
participation in these plans will be at your own expense.

     The Company has been informed by its insurance agent that you will be 
permitted to continue your group term life insurance coverage under the 
Company's policy with The Guardian through December 31, 1998.  The Company has 
also been informed by its insurance agent that you will be permitted to convert 
your group life insurance coverage with The Guardian to an

Ms. Elisabeth Elterman

Page 2


individual whole life policy with a death benefit of $180,000 within 31 days of
December 31, 1998. Our insurance agent has informed us that no medical 
examination will be necessary if you exercise your conversion right within that 
time.

     All other benefits, except as expressly provided elsewhere in this 
Agreement, will cease as of December 31, 1997.

     4.    Stock Options
           -------------

     Any options that you hold to purchase shares of the Company's Common Stock 
pursuant to its 1996 Amended and Restated incentive and Non-Qualified Stock 
Option Plan or any predecessor plan that are not vested at the time of your 
resignation (the "previously unvested options") will accelerate and vest as of 
December 31, 1997.  Nothwithstanding anything to the contrary contained in your
option agreements with respect to the previously unexercised options, your right
to exercise the previously unvested options will continue until September 30, 
1998.

     Pursuant to the terms of your option agreements, your right to exercise 
those options that vested prior to your resignation date will expire on March 
31, 1998.

     5.    Release of Claims
           -----------------

     In exchange for the payments described in paragraphs 2, 3 and 4 above, you
voluntarily agree to release the Company, its affiliates, subsidiaries,
successors and assigns, and their current and former officers, directors,
shareholders, employees, and agents in their official and personal capacities
(collectively referred to as the "Releasees") generally from all claims, demands
and liabilities of every name and nature, known or unknown, which exist or have
existed up to and including the date you sign this letter, including but not
limited to claims relating to your employment by and resignation from the
Company, including but not limited to wrongful discharge claims, breach of
contract claims, discrimination claims (including without limitation claims of
age discrimination under the Age Discrimination in Employment Act), tort claims,
statutory claims, claims for wages, bonuses, incentive compensation, vacation
pay or any other compensation or benefits, and claims for compensation or
punitive damages or attorneys fees; provided, however, that this release shall
not affect your vested rights under the Company's 401(k) retirement savings
plan.

     You acknowledge that, in entering into this agreement, the Company does not
admit that it violated any legal or other obligation to you.

you or the Company has engaged in any financial irregularities or possible 
violations of disclosure requirements or other laws.

     7.    Confidentiality
           ---------------

     You agree to keep the existence and terms of this Agreement in the 
strictest confidence and to not reveal the terms of this Agreement to any 
persons except your immediate family, your attorney and your financial advisors,
provided they also agree to keep the information confidential.

     8.    Return of Company Property
           --------------------------

           ---------

     The Company will continue your voicemail through March 31, 1998.  Your

           -------------------------------------------------

     11.   Future Cooperation
           ------------------

     You agree to cooperate reasonably with the Company and all of its

contemplation, prosecution and defense of all phases of existing, past and 
future litigation about which the Company believes you have

knowledge or information and, in doing so, to make yourself available at 
mutually convenient times and in all reasonable locations. The Company will pay 
you in advance for any pre-approved costs to be incurred in connection with your
cooperation pursuant to this paragraph, or if you incur travel expenses which 
are approved in advance by the Company, the Company will reimburse you for those
approved expenses incurred by you on or within 10 days of receipt of itemized 
bills (with receipts attached).  The reasonableness of expenses is to be 
determined under the Company's business travel policy.  For all time (except 
testimony at depositions, hearings or trials) you expend in cooperating with the
Company or any of its affiliates pursuant to this paragraph after December 31, 
1998, you shall, in addition to the Company's payment of expenses, be 
compensated at the rate of $100 per hour.

     12.   Non-Disparagement
           -----------------

     You will refrain from making any disparaging statements, taking any 
actions, or conducting yourself in any way that adversely affects the reputation
or goodwill of the Company and/or its affiliated companies and their officers, 
directors, shareholders, employees and agents.  Senior officers of the Company 
will be instructed not to make disparaging statements about you.

     13.   Legal Representation
           --------------------

     This agreement is a legally binding document and your signature will commit
you to its terms.  You acknowledge that you have been advised to discuss all 
aspects of this agreement with your attorney, that you have carefully read and 
fully understand all of the provisions of this agreement and that you are

     14.   Other Provisions
           ----------------

     You acknowledge that you have been given the opportunity to consider this 
agreement for twenty-one (21) days before signing it.  If you sign this 
agreement within less than twenty-one (21) days of the date of its delivery to 
you, you acknowledge that such decision was entirely voluntary and that you had 
the opportunity to consider this agreement for the entire twenty-one (21) day 
period.  For a period of seven (7) days from the date you sign this agreement, 
you have the right to revoke this agreement by written notice to the

between us, except the

     This AGREEMENT, made as of December 11, 1997, by and between Segue 
Software, Inc. (the "Company") and Elisabeth Elterman ("Elterman"), amends and 
supplements that certain letter agreement between the parties, dated December

     1. The Company shall use its best efforts to maintain the effectiveness of 
its registration on Form S-8 covering the issuance of shares under the Company's
1996 Amended and Restated Incentive and Non-Qualified Stock Option Plan or any 
predecessor plan thereof. In the event that such effectiveness shall lapse at a 
time when the right of Elterman to exercise any said option has not expired, 
such right to exercise shall be extended for a period of 90 days subsequent to 
the re-establishment of such effectiveness.

     2. The Company warrants and represents that as of the date hereof, it is
unaware of any claims or causes of action, of any kind, against Elterman arising
out of her relationship with the Company as a director, officer or employee.
