                                     PART I

ITEM 1. BUSINESS

GENERAL

         SPSS Inc. was incorporated in Illinois in 1975 under the name "SPSS,
Inc." and was reincorporated in Delaware in May 1993 under the name "SPSS Inc."
Unless the context otherwise requires, the term "SPSS" or "the Company" refers
to SPSS Inc., a Delaware corporation, its Illinois predecessor, and its
subsidiaries. SPSS is a multinational company that provides software and
professional services for discovering what customers want and predicting what
they will do. The Company's products and services, individually and in
combination, are primarily used by commercial organizations to integrate and
analyze market, customer, and operational data in the process of formulating
strategies and programs to interact with their customers more effectively. This
process is commonly called "data mining" or "data analysis using advanced
analytical techniques."

         Especially when combined into comprehensive analytical solutions, SPSS
products and professional services enable commercial organizations to better
target their marketing and sales programs, including:

         o        attracting new customers more efficiently;

         o        increasing sales to existing customers by improving
                  cross-selling, up-selling, and retention;

         o        forecasting and monitoring results, such as sales performance;

         o        facilitating more effective electronic commerce; and

         o        better allocating scarce resources across marketing programs.



                                       3
<PAGE>   4

         In the public sector, SPSS products and services are primarily used for
improving interactions with constituents, the detection of fraud and
non-compliance, academic research, and teaching data analysis techniques at
colleges and universities.

         The Company's products offer:

         o        a wide array of data access and data management capabilities;

         o        an extensive range of analytical techniques not found in
                  spreadsheets, query and reporting, or OLAP (On-Line Analytical
                  Processing) software; and

         o        various capabilities for the deployment of the results of
                  analyses to decision-makers or their integration into
                  databases, operational systems, and the worldwide web.

The Company's major software products include the SPSS and Clementine product
lines for general data mining and analysis (particularly in customer
relationship management applications), the Quantime, In2itive, and Surveycraft
product lines for professional market research, and the VentoMap product line
for business performance measurement. SPSS also markets certain products, most
notably SigmaPlot and SYSTAT, primarily for use in scientific research.

         In its 24 years of operation, SPSS has become a widely recognized name
in analytical software. The Company plans to leverage this leadership position
to take advantage of the increased demand for software and services that enable
organizations to systematically analyze and present data for use in
decision-making. This increased demand is particularly apparent in decisions
related to developing programs for attracting or retaining customers, as well as
forecasting and monitoring the results of such programs. The Company's
management believes that growth in the availability of data about, and
competition for, customers has substantially expanded the market for its
solutions. Further contributing to this increased demand are new versions of
certain SPSS products that effectively process large volumes of data, other new
products for the deployment of analytical results, and new service offerings for
the integration and analysis of customer data, especially information collected
at web sites.

         In summer 1993, SPSS completed an initial public offering of common
stock, $.01 par value. The common stock is listed on the Nasdaq National Market
under the symbol "SPSS." In early 1995, the Company and some stockholders sold
1,865,203 shares of common stock in a public offering.

RECENT DEVELOPMENTS

         In April 1997, SPSS entered into a 15-year sublease agreement to
sublease approximately 100,000 square feet of space in the Sears Tower in
Chicago, Illinois. During 1998, this space became the principal office space of
the Company.

         In September 1997, SPSS acquired approximately 97% of the outstanding
shares of capital stock of Quantime Limited, a corporation organized under the
laws of England in exchange for 863,049 shares of common stock of SPSS. As a
result of this transaction, Edward Sherman Ross, formerly a director of
Quantime, beneficially acquired 441,635 shares of SPSS common stock. In November
1997, SPSS acquired the remaining shares of capital stock of Quantime in
exchange for 28,175 shares of common stock of SPSS. Quantime is a developer of
software products for firms in the market research industry. Within SPSS,
Quantime is part of a business unit focused exclusively on market research
companies worldwide.



                                       4
<PAGE>   5

         In November 1997, SPSS acquired all of the outstanding shares of
capital stock of In2itive Technologies A/S, a corporation organized under the
laws of Denmark, in exchange for 140,727 shares of common stock of SPSS.
In2itive is a developer of software products for firms in the market research
industry. Within SPSS, In2itive joins Quantime as part of a business unit
focused exclusively on market research companies worldwide.

         In November 1998, SPSS acquired all of the outstanding shares of
capital stock of Surveycraft Pty Ltd., a corporation organized under the laws of
Australia, for approximately $1,700,000. Surveycraft is a developer of software
products for firms in the market research industry, and was the first such
entity to support Asian languages. Within SPSS, Surveycraft joins In2itive and
Quantime as part of a business unit focused exclusively on market research
companies worldwide.

         On December 31, 1998, SPSS acquired all of the outstanding shares of
capital stock of Integral Solutions Limited ("ISL"), a corporation organized
under the laws of England, for an aggregate purchase price of approximately
$7,000,000. SPSS may be required to make additional payments up to approximately
$7,000,000 in future years to the former owners of ISL based upon the attainment
of specific operating results. An additional payment of approximately $3,900,000
was made in January 2000. The additional payments will be recorded as an
adjustment to the purchase price paid by SPSS for the stock of ISL in the
periods in which the payments are determinable. ISL is a developer of software
products for data mining. SPSS plans to further develop these ISL products to
create a comprehensive data mining workbench targeted at large organizations as
part of its overall strategy for more enterprise-wide sales of SPSS software and
services.

         On November 29, 1999, SPSS acquired all of the outstanding shares of
Vento Software, Inc. in exchange for 546,060 shares of common stock of SPSS.
Vento's assets include the VentoMap product line, a series of industry-specific
software products for business performance measurement, and a proprietary
methodology for the delivery of related professional services. SPSS plans to
further develop these Vento products and integrate its data mining capabilities,
as well as use the Vento professional services methodology as the basis for
expanded consulting activities supporting the implementation of its analytical
solutions.

         On December 24, 1999, SPSS acquired the VerbaStat software program from
DataStat, S.A., a corporation organized under the laws of Belgium, for
approximately $1,000,000. VerbaStat is a software tool for computer aided coding
of open-ended survey questions. SPSS plans to further develop this product and
integrate its capabilities into its next-generation solution for firms in the
market research industry.

INDUSTRY BACKGROUND

         The analysis of data using advanced analytical techniques, whether
traditional statistical methods such as factor analysis and regression, or other
methods such as neural networks and decision trees, enables decision-makers to
draw reliable conclusions from numerical information about a given subject. Such
systematic analysis of numbers goes back to the seventeenth century, when
statistics were used in determining insurance and annuity rates, as well as by
political leaders in developing more effective economic policies. The
fundamental purpose and power of this kind of data analysis remains the same
today: to help decision makers understand and resolve problems by uncovering the
causes underlying current conditions and predicting future events. Such benefits
are particularly apparent in contemporary data mining applications, which often
involve the examination of extremely large amounts of data stored



                                       5
<PAGE>   6

in specialized databases known as "data warehouses" or "data marts," as well as
in analyzing data directly related to activities on the world wide web.

         SPSS has historically developed and marketed its products and services
for a wide range of data analysis applications. Recently, the Company began to
focus more specifically upon the analysis of data related to customer attitudes
and behavior. SPSS believes that demand for its analytical capabilities will
continue to grow as decision-making becomes more complex, as the consequences of
decisions (particularly those related to customer requirements) become more
significant, and as more data is available for analysis. To meet this demand,
colleges and universities are training increasing numbers of people in the use
of appropriate analytical methods. In addition, new technology has made more
usable and affordable the application of advanced analysis to large data sets,
as well as the distribution of analytical results to wider audiences within an
organization.

         Vendors providing spreadsheets, query and reporting tools, and OLAP
software serve the largest part of the general market for data analysis
software. The widespread use of these tools is due to their effectiveness in
providing basic summaries of historical data, such as what sales were by region,
how many customers purchased a particular product, or what the default rate was
on loans.

         A smaller yet sizable and growing part of the market uses more advanced
analytical capabilities for dealing with issues of causality and prediction.
Such capabilities enable corporations to predict sales for the upcoming season,
determine the best targets for a new product, or distinguish good and bad credit
risks prior to extending credit terms. Spreadsheet, query and reporting, and
OLAP software usually lack the advanced analytical capabilities to build the
predictive models needed to address these types of questions.

         SPSS believes the worldwide demand for its analytical solutions will
grow as:

     o    competition for customers accelerates dramatically due to the
          combination of increasingly global markets, deregulation in many
          industries, and the ubiquity of information on the web;

     o    commercial and public sector organizations demand more accountability
          for spending and on invoices from suppliers;

     o    organizations require more useful information from the increasing
          amount of data being collected, organized, and stored;

     o    the number of people with a working knowledge of analytical methods
          continues to grow significantly; and

     o    easier-to-use software, increases in computing power, and additional
          options for the deployment of results eliminate many historical
          barriers to the use of advanced analytical capabilities.

MARKETS

         SPSS customers come from various industries and use SPSS products in a
wide range of applications. The Company focuses, however, on the following
market areas:

Customer Relationship Management. Firms in various industries use SPSS software
and services to improve customer interactions, including:



                                       6
<PAGE>   7

     o    targeting promotional campaigns;

     o    test-marketing new products;

     o    identifying changing customer characteristics;

     o    measuring customer satisfaction;

     o    forecasting sales; and

     o    streamlining and personalizing web sites and other applications.

Business Intelligence. Firms in various industries use SPSS software and
services to analyze information in corporate databases, particularly data
warehouses, for an extensive range of applications. The Company's technology
extends the capabilities provided by other business intelligence tools such as
OLAP software, query and reporting programs, ETL
(extraction-transformation-load) products, and multidimensional data stores.
Moreover, SPSS software for business performance measurement gives executives
the ability to monitor critical day-to-day operations by viewing key performance
indicators and drilling down for more information as needed.

Market Research. Almost all of the top market research firms worldwide use the
Company's software and services to conduct the process of survey research, from
designing questionnaires to collecting data through multiple sources (especially
telephone and the web) to producing customized tabulations to developing
advanced analytical models.

Government. SPSS software and services are used in almost every country of the
world, at all levels of government, and in civilian as well as defense agencies.
The Company's products, for example, are used as part of the efforts of the
Internal Revenue Service of the United States to modernize its tracking systems,
furnish critical information used by many municipal public safety agencies, have
become the standard marketing tools in the recruitment programs of the United
States Armed Forces, and are employed as a statistical system for many national
census programs.

Education. SPSS software is used at virtually every major college and
university. In addition to their use in teaching statistics at the undergraduate
and graduate levels, the Company's products are used in academic research of all
types. Academic administrators also use SPSS software to monitor aspects of
their operations, such as attrition rates, changes in the demographic profile of
student populations, and the success of fund-raising activities.

Scientific Research. SPSS products are used in a wide variety of research and
development efforts across academic, government, and corporate institutions. The
Company's software provides data analysis and presentation tools in such
applications as pharmacology, clinical trials, environmental monitoring, and
experimental modeling.

ANALYTICAL SOLUTIONS AND SOFTWARE PRODUCTS

         The Company's software products enable its customers to analyze data,
including the generation of reports, graphs, and models, on a wide variety of
computing platforms. Many of these software products can be used either
stand-alone or as part of an integrated system. SPSS provides services with its
products, such as developing plans to align analytical efforts with
organizational goals, collecting and storing data, building predictive models,
and deploying the results of analyses throughout an organization. Certain
combinations of software products and professional services are marketed by SPSS
as "analytical solutions."




                                       7
<PAGE>   8

     In general, SPSS software products are:

     o   comprehensive in function, spanning the process of analysis from data
         access to advanced predictive techniques;

     o   modular, allowing customers to purchase only the functionality they
         need;

     o   integrated, enabling the use of multiple SPSS products in combination
         to tackle particularly complex problems;

     o   embeddable, facilitating the integration of SPSS analytical
         capabilities into other systems, including web sites;

     o   tailored to desktop operating environments for greater ease-of-use,
         including browser-based environments for the delivery of results;

     o   available on most popular computing platforms, and

     o   for some products, localized for use in France, Germany, Italy,
         Poland, Japan, Taiwan, Korea, China, and Spanish-speaking countries.

         SPSS products are most often used in combination, particularly in
customer relationship management applications. Such combinations are required
because customers receive different types of value from different types of
analysis of the same data. For example, a customer might use the SPSS market
research products to collect information about its customers' preferences and
integrate this data with operational and purchased demographic information in a
data warehouse. The customer might then analyze the data with one or more SPSS
data mining and analysis products to create customer profiles for use in
marketing programs to attract certain types of prospects. Finally, the customer
could monitor the performance of these marketing programs with the SPSS business
performance measurement products.

         There are four categories of SPSS products:

         1. Data mining and analysis products, for examining data in databases,
         data warehouses, and other file types. In customer relationship
         management applications, these products are primarily used to segment
         customers by various outcomes, such as the purchase of a product or the
         renewal of a contract, as well as to predict their future behavior and
         the actions of prospects with similar profiles. SPSS offerings for data
         mining and analysis are in either the SPSS or Clementine product lines.

         o        The SPSS product line provides a broad range of statistical
                  methods. Users create tables, graphs, OLAP reports, and
                  predictive models in both desktop and distributed computing
                  environments. While there are some variations according to the
                  version and computing platform, a typical configuration in a
                  customer relationship management application is an SPSS Base
                  and related add-on and stand-alone products. The SPSS Base
                  includes the user interface, data connectivity, data editing,
                  reporting, graphing, and general statistical capabilities.
                  Add-on products require the SPSS Base to operate and become
                  seamlessly integrated with it upon installation. These
                  optional offerings provide additional functionality specific
                  to a particular type of analysis. Stand-alone products do not
                  require the SPSS Base to operate and perform specific
                  applications, such as facilitating certain types of data entry
                  or



                                       8
<PAGE>   9

                  performing certain kinds of advanced analysis. These
                  stand-alone products are developed by SPSS or third parties.
                  See "Business - Reliance on Third Parties." Certain
                  stand-alone products in the SPSS product line are particularly
                  notable because their capabilities provide value to
                  organizations beyond what is typically realized with
                  general-purpose statistical products. AnswerTree, for example,
                  enables highly visual decision-trees to be used for developing
                  customer profiles. DecisionTime creates time-series forecasts,
                  which can then be distributed for review and scenario analysis
                  by managers and executives with its companion product, WhatIf?
                  SmartViewer Web Server distributes the results of analysis to
                  decision-makers via the web. SmartScore deploys the results of
                  analyses into operational systems, including web sites, as
                  well as into databases or data warehouses.

         o        The Clementine product line offers advanced analytical
                  capabilities for a variety of data mining applications in
                  desktop and distributed computing environments. With its
                  unique user interface, Clementine enables operating managers
                  to easily incorporate their business knowledge with data to
                  develop predictive models. Models built in Clementine can then
                  be deployed for use in other software applications with the
                  Clementine Solution Publisher. While the SPSS and Clementine
                  product families are already usable together, the Company
                  plans to more tightly integrate their functionality in the
                  future.

         2. Business performance measurement products. The VentoMap product line
         enables executives to monitor the effectiveness of their operations,
         particularly with respect to customer relationship management items
         such as retention rates, the number of new sales, and average account
         size. Each implementation is based on a data model specific to an
         industry or application and includes the use of a proprietary process
         for identifying key performance indicators ("KPIs") appropriate to that
         business. Executives can easily view these KPIs and then drill down for
         more detailed information to get a better understanding of what caused
         the results.

         3. Market research products. The Quantime, In2itive, and Surveycraft
         product lines provide comprehensive solutions for professionals in the
         market research industry. These sets of offerings have their particular
         strengths: the Quantime products, for example, are distinguished by
         their extensive functionality, while the In2itive products feature a
         more modern user interface, and the Surveycraft products are more
         easily localized for use in Asian markets. The Company plans to combine
         the strengths of these product lines, as well as improve their ability
         to communicate with other SPSS products, in its next-generation
         solution for market research professionals.

         4. Scientific products. Scientists and engineers in various technical
         applications use the SigmaPlot and SYSTAT product lines for data
         presentation and analysis.

         SPSS software products have received numerous favorable reviews from
trade and other publications. Some of the analytical capabilities of the
products are available as components, which software developers can integrate
into their own applications. A full range of services, including consulting,
training, and technical support, is available for all products.


SOFTWARE PRICING

         The Company's licensing and pricing alternatives vary widely depending
upon the product, platform, and quantities licensed.



                                       9
<PAGE>   10

         For the SPSS product line, list prices in North America for perpetual
single-user licenses of desktop products are approximately $999 for the SPSS
Base and range from $299 to $2,499 for other products. Multi-user network and
site licenses can be significantly higher and require annual payments. List
prices of annual licenses for SPSS product line products on mainframes,
minicomputers, UNIX workstations, and Windows NT servers range from $4,500 to
$15,000, while perpetual licenses run from $10,000 to over $30,000. SPSS
licenses outside of North America are more often sold as annual licenses.

         Clementine is available under all license types listed above, with a
typical sale of between $50,000 and $75,000.

         VentoMap installations usually involve the combination of a perpetual
license for the software and a consulting engagement to determine the KPIs and
build the data warehouse. The price of VentoMap installations typically ranges
from $500,000 to $1,000,000.

         Although available on perpetual licenses, the market research products
are most often licensed on an annual basis, where the amount of the annual fee
depends on the number of modules involved in the customer's configuration and
the number of users of each module. Such annual fees range from approximately
$1,000 to over $1 million. The rate of renewal of these licenses has
historically been very high (over 90%).

         Science products are usually sold as perpetual licenses for between
$500 and $1,300, with discounts for volume purchases. Multi-user and site
licenses are also available and require annual payments.

PUBLICATIONS AND STUDENT SOFTWARE

         SPSS authors and regularly updates a number of publications that
include user manuals and instructional texts. The Company also develops student
versions of its SPSS Base and SYSTAT products, which are designed for classroom
use with SPSS textbooks or other instructional materials. Since February 1993,
the College Division of Prentice Hall, under the terms of a semi-exclusive,
worldwide agreement, has distributed SPSS publications and student software. See
"Business-Prentice Hall Agreement." SPSS also has arrangements with other
publishers to include the SPSS Student Version in textbooks with data sets
specific to the text.

TRAINING AND CONSULTING

         SPSS offers a comprehensive training program with courses covering
product operations, data analytical concepts, and particular analytical
applications. These courses are regularly scheduled in cities around the world.
Organizations may also contract for on-site SPSS training tailored to their
specific requirements.

         The Company offers consulting and customization services, where an
engagement may involve the development of plans to align analytical efforts with
organizational goals, the collection and organization of data, the building of
predictive models, and the deployment of the results of analyses throughout an
organization.



                                       10

SALES AND MARKETING

         The SPSS sales and marketing strategy emphasizes its ability to deliver
high value products and analytical solutions, particularly for customer
relationship management, business intelligence, market research, and business
performance measurement applications. The Company's management believes its data
mining and advanced analysis capabilities are the keys to differentiating SPSS
from its competitors.

         SPSS markets and sells its products and services primarily through a
well-developed, worldwide direct sales and telesales organization. Historically,
advertising, direct mail, tradeshow attendance, and customer references have
proven the most effective ways of generating new sales for the telesales
organization. Although varying widely, sales made by the telesales organization
are typically completed within 30 days and average about $1,400. The Company's
database of existing customers provides an effective source for selling add-on
products, upgrades, and training or consulting services. Customers regularly
receive direct mail from SPSS on its products and services.

         As SPSS increases its emphasis on the sale of higher-priced products
and analytical solutions, the Company is increasing the size of its direct sales
force along with its pre-sales support staff and consulting personnel. Most of
this direct sales force is now organized by industry to better understand the
business issues facing executives in that industry and more effectively relate
SPSS products and analytical solutions to their needs. For large sales
opportunities, SPSS sales representatives and technical sales personnel
personally visit prospects to make presentations, give product demonstrations,
and provide pre-sales consulting. SPSS also has partner relationships with other
leading companies, which represent additional channels for sales and leads for
the Company's higher-priced offerings.

         In addition to its headquarters in Chicago, SPSS has sales offices
across the United States, including the Washington D.C. area, New York, San
Francisco, Cincinnati, Denver, and Miami. The SPSS international sales operation
consists of thirteen sales offices in Europe and the Pacific Rim, as well as
over 60 licensed distributors. Overall, SPSS is represented in over 50
countries. Transactions are customarily made in local currencies.

         Student versions are published by Prentice Hall and sold by more than
300 Prentice Hall sales representatives working directly with faculty on college
campuses worldwide. The arrangement also permits Prentice Hall to bundle its
various textbooks on statistics, market research, and quality improvement with
SPSS student versions.

         Current users of SPSS products comprise a significant source of new
sales leads. Also important are the expert reviews of SPSS software in trade and
market-specific publications. The Company's marketing communications program
includes advertising in trade and market-specific publications, advertising on
the worldwide web, direct mail, exhibiting at trade shows, participating in and
speaking at professional association meetings, sponsoring seminars for prospects
and customers, publishing its customer magazine and conducting user group
meetings.

CUSTOMER SERVICE AND TECHNICAL SUPPORT

         SPSS provides extensive customer service and technical support by
telephone, fax, mail and the worldwide web, promoting customer satisfaction and
obtaining feedback on new products. Technical support services provided to all
licensees include assistance in product installation and operation, as well



                                       11
<PAGE>   12

as limited consulting in the selection of different analytical methods and the
interpretation of results. Additional technical support services are available
on a fee basis.

PRODUCT DEVELOPMENT

         SPSS plans to continue expanding its product offerings through the
development of new software products, the enhancement of existing products, the
acquisition of technologies and businesses complementary to the Company's
existing product lines, and the formation of partnerships with value-added
resellers or other third parties serving selected markets. The Company's product
development strategy is primarily focused on improving:

         o        improving the scalability of its products to work with larger
                  data sets;

         o        expanding the ability of its products to integrate with other
                  applications and be tailored to customer-specific
                  requirements; and

         o        enhancing the ways results of analyses can be deployed
                  throughout an organization, making them readily accessible to
                  decision-makers as well as used in various operational systems
                  and web sites; and

         o        extending the formidable analytical capacity already available
                  in its products.

         The Company's specialists in user interface design, software
engineering, quality assurance, product documentation, and the development of
analytical algorithms are responsible for maintaining and enhancing the quality,
usability, and accuracy of all SPSS software. The product development
organization is also responsible for authoring and updating all user
documentation and other publications. In addition, SPSS maintains ongoing
relationships with third-party software developers for the development of
specialized software products and the acquisition of technology that can be
embedded in SPSS products.

         Most statistical algorithms used by SPSS in its products are published
for the convenience of its customers. SPSS employs full-time statisticians who
regularly research and evaluate new algorithms and statistical techniques for
inclusion in the Company's products. SPSS also employs statistically-trained
professionals in its documentation, quality assurance, software design and
software engineering groups.

         SPSS intends to continue to invest in product development. In
particular, the Company's 2000 development plan includes additional server
versions of offerings in the SPSS product line and updates to the SPSS product
line and related server versions, Clementine, SmartViewer Web Server, Quantime,
In2itive, SYSTAT, SigmaPlot, and other products. SPSS also intends to further
develop analytical components, which are products designed for use by software
developers for integration into other applications.

         In the past, SPSS has experienced delays in the introduction of new
products and product enhancements, primarily due to difficulties with particular
operating environments and problems with technology provided by third parties.
These delays have varied depending upon the size and scope of the project and
the nature of the problems encountered. From time to time SPSS discovers "bugs"
in its products, which are resolved through maintenance releases or periodic
updates, depending on the seriousness of the defect.

         The SPSS product development staff currently includes approximately 193
professionals organized into groups for software design, algorithm development,
software engineering, documentation, quality assurance, and product
localization. The Company's expenditures for product development,



                                       12
<PAGE>   13

including capitalized software, were approximately $19.6 million in 1997, $22.8
million in 1998, and $27.6 million in 1999.

         SPSS also uses independent contractors in its product development
efforts. Sometimes the Company uses these contractors to obtain technical
knowledge and capability that it lacks internally. For example, contractors are
engaged to perform conversions of SPSS products to computing platforms with
which SPSS is unfamiliar or which are too costly to acquire for development
purposes. SPSS has outsourced maintenance, conversion, and new programming for
some products to enable its internal development staff to focus on products that
are of greater strategic significance. The Company sometimes uses independent
contractors to augment its development capacity at a lower cost.

MANUFACTURING AND ORDER FULFILLMENT

         To assure speed and efficiency in the manufacturing, order fulfillment,
and delivery of its products, SPSS entered into an agreement with IBM in
February 1993. From April 1993 to December 1996, IBM performed all diskette and
CD-ROM duplication, documentation printing, packaging, warehousing, fulfillment,
and shipping of SPSS products in the Western Hemisphere for SPSS. In January
1997, the IBM agreement was replaced with a similar agreement with Banta Global
Turnkey. These services were recently expanded worldwide. SPSS believes that,
because of the capacity of these third party distribution centers and their
around-the-clock operation, it can easily adapt to peak period demand, quickly
manufacture new products for distribution, and effectively respond to
anticipated sales volumes.

COMPETITION

         The Company's traditional market for statistical software is both
highly competitive and fragmented. SPSS is among the largest companies in the
statistical software market and, based upon sales and comparative assessments in
trade publications, the Company believes that it competes effectively against
its competitors, particularly on desktop computing platforms. SPSS considers its
primary worldwide competitor to be the larger and better financed SAS Institute.
StatSoft Inc., Mathsoft, and Minitab, Inc. are also competitors, although their
annual revenues from statistical products are believed to be considerably less
than the revenues of SPSS. In addition to competition from other statistical
software companies, SPSS also faces competition from providers of software for
specific statistical applications.

         In the data mining, customer relationship management, and business
performance measurement markets, SPSS faces competition from many larger and
better funded companies, including SAS, IBM, HNC, NCR, Oracle, and others, as
well as recent entrants, such as Attune, E.piphany, and Net Perceptions, many of
whom specialize in customer relationship management in e-commerce settings. With
the exception of SAS, the Company believes that these competitors do not
currently offer the range of analytical capability available from SPSS and, as a
result, are both competitors and potential partners for the Company's
technology.

         SPSS holds a dominant position in the market for solutions to the
market research industry. The Company believes that there are no competitors in
this market who are larger and better financed; the annual revenues of such
vendors as Sawtooth Software, Computers for Marketing Corporation, and Pulse
Train Technology are estimated to be considerably less than the Company's
revenues from its market research products and services.



                                       13
<PAGE>   14

         In all markets, SPSS competes primarily on the basis of the usability,
functionality, performance, reliability, and connectivity of its software
products. The significance of each of these factors varies depending upon the
anticipated use of the software and the analytical training and expertise of the
customer. To a lesser extent, SPSS competes on the basis of price and thus
maintains pricing and licensing policies to meet market demand. The Company
believes it is able to compete successfully due to the graphical user interface,
comprehensive analytical capabilities, efficient performance characteristics,
local language versions, consistent quality, and connectivity features of its
software products, as well as its worldwide distribution capabilities and widely
recognized name.

         In the future, SPSS may face competition from other new entrants into
its markets. SPSS could also experience competition from companies in other
sectors of the broader market for business intelligence software, such as
providers of OLAP and analytical application software, as well as from companies
in other sectors of the broader market for customer relationship management
applications, such as providers of sales force automation and collaborative
software, who could add enhanced analytical functionality to their existing
products. Some of these potential competitors have significantly more capital
resources, marketing experience, and research and development capabilities than
SPSS. Competitive pressures from the introduction of new products by these
companies or other companies could have a material adverse effect on SPSS.

INTELLECTUAL PROPERTY

         SPSS attempts to protect its proprietary software with trade secret
laws and internal nondisclosure safeguards, as well as copyrights and
contractual restrictions on copying, disclosure and transferability that are
incorporated into its software license agreements. SPSS licenses its software
only in the form of executable code, with contractual restrictions on copying,
disclosures and transferability. Except for licenses of its products to users of
large system products and annual licenses of its desktop products, SPSS licenses
its products to end-users by use of a "shrink-wrap" license, as is customary in
the industry. It is uncertain whether these license agreements are legally
enforceable. The source code for all of the Company's products is protected as a
trade secret and as unpublished copyrighted work. In addition, SPSS has entered
into confidentiality and nondisclosure agreements with its key employees.
Despite these restrictions, the possibility exists for competitors or users to
copy aspects of the Company's products or to obtain information which SPSS
regards as a trade secret. SPSS has no patents, and judicial enforcement of
copyright laws and trade secrets may be uncertain, particularly outside of North
America. Preventing unauthorized use of computer software is difficult, and
software piracy is expected to be a persistent problem for the packaged software
industry. These problems may be particularly acute in international markets.

         SPSS uses a variety of trademarks with its products. Management
believes the following are material to its business:

         o        SPSS is a registered trademark used in connection with
                  virtually all of the Company's products

         o        Clementine is a registered trademark used in connection with
                  the Company's acquired product line from Integral Solutions
                  Limited;

         o        WhatIf? and DecisionTime are the subject of pending
                  applications for registration.

         o        AnswerTree is a registered trademark and is an add on product
                  to the SPSS product family;



                                       14
<PAGE>   15

         o        SmartViewer is a registered trademark and is an add on product
                  to the SPSS product family;

         o        Vento and VentoMap are registered trademarks used in
                  connection with the Company's acquired Vento products on all
                  platforms;

         o        Quantime is an unregistered trademark used in connection with
                  the Company's acquired Quantime products on all platforms;

         o        In2itive Technologies is a registered trademark in Denmark and
                  is used in connection with the Company's acquired In2itive
                  products on all platforms;

         o        Surveycraft is an unregistered trademark used in connection
                  with the Company's acquired Surveycraft products;

         o        SYSTAT is a registered trademark used in connection with the
                  Company's SYSTAT products on all platforms;

         o        SigmaPlot is a registered trademark used in connection with
                  the Company's acquired products on all platforms; and

         o        allclear is a registered trademark used in connection with the
                  Company's acquired Clear products on all platforms.

         Some of these trademarks comprise portions of other SPSS trademarks.
SPSS has registered some of its trademarks in the United States and some of its
trademarks in a number of other countries, including the Benelux countries,
France, Germany, the United Kingdom, Japan, Singapore and Spain. Registration of
a trademark confers a number of advantages over reliance on common law rights.
Registration of a trademark generally presumes the validity of the mark and the
registrant's ownership of and exclusive right to use the mark and, in some
jurisdictions, constitutes constructive notice of ownership sufficient to
eliminate any defense of good faith adoption or use after the date of
registration.

         Due to the rapid pace of technological change in the software industry,
SPSS believes that patent, trade secret, and copyright protection are less
significant to its competitive position than factors such as the knowledge,
ability, and experience of the Company's personnel, new product development,
frequent product enhancements, name recognition, and ongoing reliable product
maintenance and support.

         SPSS believes that its products and trademarks and other proprietary
rights do not infringe the proprietary rights of third parties. There can be no
assurance, however, that third parties will not assert infringement claims in
the future.

RELIANCE ON THIRD PARTIES

         SPSS entered into a perpetual nonexclusive license agreement, the HOOPS
agreement, with Autodesk Inc. that permits SPSS to incorporate a graphics
software program known as the HOOPS Graphics System into the Company's products.
Under the terms of the HOOPS agreement, SPSS is required to pay royalties to
Autodesk based on the amount of revenues received by SPSS from products that
incorporate the HOOPS Graphics System. SPSS may terminate the HOOPS agreement at
any time.



                                       15
<PAGE>   16

Autodesk may terminate the HOOPS agreement on the occurrence of a material,
uncured breach of the HOOPS agreement by SPSS.

         SPSS also licenses certain other software programs from third-party
developers and incorporates them into its products. Many of these licenses are
exclusive worldwide agreements that terminate on various dates. SPSS believes
that it will be able to renew non-perpetual licenses or obtain substitute
products if needed.

BANTA GLOBAL TURNKEY SOFTWARE DISTRIBUTION AGREEMENT

         In January 1997, SPSS entered into an agreement with Banta Global
Turnkey (Banta) under which Banta manufactures, packages, and distributes SPSS
software products to its customers worldwide. The Banta agreement had an initial
three-year term, and automatically renews thereafter for successive periods of
one year. The Banta agreement was renewed in January 2000. Either party may
terminate this agreement with 180 days written notice. If Banta terminates the
agreement for convenience or for any reason other than for cause, then during
the 180-day notice period Banta will assist SPSS in finding a new vendor. If
either party materially breaches its obligations, the other party may terminate
the Banta agreement for cause by written notice. This termination notice for
cause must specifically identify the breach or breaches, upon which the
termination based and will be effective 180 days after the notice is received by
the other party, unless the breach(es) is (are) corrected during the 180 days.

PRENTICE HALL AGREEMENT

         SPSS entered into an agreement with Prentice Hall in February 1993.
Under this agreement, SPSS granted to Prentice Hall the exclusive, worldwide
right to publish and distribute all SPSS publications, including student
versions of SPSS for DOS and Windows. The initial agreement had a five-year term
which ended in 1998.

         SPSS entered into a new five-year contract with Prentice Hall in April
1998. Prentice Hall has an option to renew this contract for five additional
years if it pays SPSS $2,750,000 or more during the term of this agreement. If
Prentice Hall does not pay SPSS $1,100,000 by the end of the second year of the
contract, SPSS has the option to make Prentice Hall's right to distribute
Student Versions non-exclusive. The key differences in the new contract are: 1)
Prentice Hall may only operate in certain geographic territories instead of
having worldwide rights; 2) Prentice Hall only has rights to certain books and
SPSS may sell any book (previously SPSS had to purchase the books from Prentice
Hall); and (3) SPSS can, within certain guidelines, license other publishers to
bundle versions of the SPSS Student Version with their textbooks.

COMPUTER SOFTWARE DEVELOPMENT COMPANY

         In 1981, SPSS entered into a software development agreement with the
Computer Software Development Company to obtain funding of approximately $2
million for development of software including two large system products, SPSS
Graphics and SPSS Tables, and one desktop product, SPSS/PC+ Tables. SPSS entered
into two software purchase agreements with Computer Software Development under
which SPSS is required to pay Computer Software Development royalties through
the year 2001 based on a percentage of "net revenues" (as defined in the
agreements) from large system software products developed with Computer Software
Development funds. Under these agreements, SPSS incurred royalties payable of
approximately $249,000 in 1997, $234,000 in 1998 and $237,000 in



                                       16

1999 to Computer Software Development. Norman Nie, the Chairman of the Board of
SPSS, is a limited partner of Computer Software Development.

SEASONALITY

         The Company's quarterly operating results fluctuate due to several
factors, including:

         o        the number and timing of product updates and new product
                  introductions;

         o        delays in product development and introduction;

         o        purchasing schedules of its customers;

         o        changes in foreign currency exchange rates;

         o        product and market development expenditures;

         o        the timing of product shipments;

         o        changes in product mix; and

         o        timing and cost of acquisitions and general economic
                  conditions.

         If forecasts of future revenues fall below expectations, operating
results may be adversely affected because the Company's expense levels are to a
large extent based on these forecasts. Accordingly, SPSS believes that
quarter-to-quarter comparisons of its results of operations may not be
meaningful and should not be relied upon as an indication of future performance.
SPSS has historically operated with very little backlog because its products are
generally shipped as orders are received. As a result, revenues in any quarter
are dependent on orders shipped and licenses renewed in that quarter. SPSS has
experienced a seasonal pattern in its operating results, with the fourth quarter
typically having the highest operating income. For example, excluding special
general and administrative, merger-related, and acquired in-process technology
charges, the percentage of the Company's operating income realized in the fourth
quarter was 36% in 1997, 35% in 1998 and 38% in 1999. In addition, the timing
and amount of the Company's revenues are affected by a number of factors that
make estimation of operating results prior to the end of a quarter uncertain. A
significant portion of the Company's operating expenses is relatively fixed, and
planned expenditures are based primarily on revenue forecasts. More
specifically, in the fourth quarter, the variable profit margins on modest
increases in sales volume at the end of the quarter are significant. If SPSS
fails to achieve these fourth quarter revenue increases, then a material
reduction in net income for the fourth quarter and the full year could result.
Generally, if revenues do not meet the Company's expectations in any given
quarter, operating results will be adversely affected. SPSS cannot provide
assurance that profitability on a quarterly or annual basis in the future.

EMPLOYEES

         SPSS has approximately 919 employees, approximately 520 domestically,
and 399 internationally. Of the approximate 919 employees, there are
approximately 561 in sales and marketing, 193 in product development and 166 in
general and administrative. SPSS believes it has generally good relationships
with its employees. None of the Company's employees are members of labor unions.

         The Company's revenues from operations outside of North America
accounted for approximately 50%, in 1997, 47% in 1998 and 50% in 1999. SPSS
expects that revenues from international operations will continue to represent a
large percentage of its net revenues and that this percentage may increase,
particularly as the Company continues to translate its products into additional
languages. Various risks may affect international operations, including greater
difficulties in accounts receivable collection, longer payment cycles, exposure
to currency fluctuations, political and economic instability, and the burdens of
complying with a wide variety of foreign laws and regulatory requirements. SPSS
also believes that it is exposed to greater levels of software piracy in
international markets because of the weaker protection afforded intellectual
property in some foreign jurisdictions. As SPSS expands its international
operations, the risks described above could increase and have a material adverse
effect on SPSS. See "Business - Sales and Marketing," "Management's Discussion
and Analysis of Financial Condition and Results of Operations," and Note 2,
Domestic and Foreign Operations, of the "Notes to Consolidated Financial
Statements."

ITEM 2. PROPERTIES

         The Company's principal administrative, marketing, training and product
development and support facilities are located in Chicago, Illinois. During
1997, SPSS entered into a 15-year sublease agreement to sublease approximately
100,000 square feet of office space in the Sears Tower. This space became the
principal Chicago offices of SPSS in 1998. The aggregate annual gross rental
payment on this lease was approximately $1,749,000 in 1999.

         In addition, SPSS leases office space in California, Colorado,
Massachusetts, Virginia, New York, Pennsylvania, Ohio, Florida, The Netherlands,
The United Kingdom, Germany, Sweden, France, Singapore, Australia, Japan,
Denmark, and India.

         SPSS believes its facilities are suitable and adequate for its present
needs. The Company plans to expand its facilities in 2000 in Chicago, the United
Kingdom, Denmark, and Australia.

ITEM 3. LEGAL PROCEEDINGS

         Currently, there is no material pending legal proceeding to which SPSS
or any of its subsidiaries is a party or to which any of their property is
subject.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

         Not applicable.

As of March 17, 2000, there were 458 holders of record of the Company's common
stock.

         SPSS has never declared or paid any cash dividends on its capital
stock. The Company currently intends to retain its earnings to fund future
ongoing operations and future capital requirements of its businesses. SPSS does
not anticipate paying any cash dividends in the foreseeable future. See
"Management's Discussion and Analysis of Financial Conditions and Results of
Operations -- Liquidity and Capital Resources."

RECENT SALES OF UNREGISTERED SECURITIES

         On November 29, 1999, SPSS acquired Vento Software, Inc., a Florida
corporation, in exchange for 546,060 shares of SPSS common stock in an
acquisition accounted for as a pooling of interests, pursuant to an acquisition
agreement among SPSS, Vento and the shareholders of Vento. The sale of stock to
the Vento shareholders was exempt from registration pursuant to Section 4(2) of
the Securities Act because the sale did not involve a public offering of stock.
A Registration Statement on Form S-3 was subsequently filed and became effective
on February 24, 2000.

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

OVERVIEW

         The original Statistical Package for the Social Sciences was introduced
in 1969, and SPSS was incorporated in 1975. The first SPSS products were almost
exclusively used by academic researchers working on mainframe systems. SPSS has
subsequently transformed and enhanced its core product technology, broadened its
customer base into the corporate and government sectors, significantly expanded
its sales and marketing capabilities, acquired ten corporate entities and
product offerings, and adapted its products to changing hardware and software
technologies. Approximately 68% of 1999 revenues came from sales to customers in
corporate settings, with another 18% in academic institutions and 14% in
government agencies.

         In recent years, SPSS has experienced a significant shift in the
sources of its revenues. Between 1995 and 1999, revenues from its analytical
solutions increased from less than 1% to over 12% of total net revenues and
market research revenues rose from 17% to 23%. In contrast, revenue from SPSS
statistical products and services declined from 82% to 65% of net revenues.
Management expects these trends to continue in 2000.

</TABLE>


COMPARISON OF TWELVE MONTHS ENDED DECEMBER 31, 1997, 1998 AND 1999.

Net Revenues. Net revenues increased from $111,106,000 in 1997 to $123,472,000
in 1998, an increase of 11% from 1997, and to $141,930,000 in 1999, and an
increase of 15% from 1998. These increases were primarily due to growth in
analytical solutions revenues of 122% in 1998 and 99% in 1999, as well as
increases in market research revenues of 18% in 1998 and 28% in 1999. Growth in
analytical solutions revenues in 1998 was primarily due to the introduction of
new data mining products, while such increases in 1999 were primarily due to
additional new data mining products and sales of the newly acquired Clementine
products. Growth in market research revenues in 1998 was primarily due to sales
of the telephony product for data collection, while such increases in 1999 were
primarily due to the introduction of a new web data collection product,
revenues from the newly acquired Surveycraft products and an increased number of
large transactions with major customers. Offsetting this revenue growth were
increases in statistics revenue of 4% in 1998 and 3% in 1999, primarily due to
shifts in sales and marketing resources toward developing the higher-growth
markets for analytical solutions, as well as reflecting the lower overall growth
rate in the market for general-purpose statistical products. Revenues were
adversely affected by foreign currency exchange rates for the three years
described.



                                       23
<PAGE>   24

Cost of Revenues. Cost of revenues consists of costs of goods sold, amortization
of capitalized software development costs, and royalties paid to third parties.
Cost of revenues increased from $9,835,000 in 1997, to $10,048,000 in 1998 and
to $12,663,000 in 1999. These costs increased 2% in 1998 due to higher sales
levels and 26% in 1999 due to higher sales levels and higher amounts of
capitalized software amortized. As a percentage of net revenues, cost of
revenues decreased from 9% in 1997 to 8% in 1998 and increased to 9% in 1999.

Sales and Marketing. Sales and marketing expenses increased from $54,503,000 in
1997 to $60,413,000 in 1998 and to $68,277,000 in 1999, an increase of 11% in
1998 and 13% in 1999. These increases were due to expansion of the domestic and
international sales and marketing organizations, as well as increased salary,
commission and payroll-related expenses. Sales and marketing expenses were
partially offset by the effects of changes in foreign currency exchange rates
each year. As a percentage of net revenues, sales and marketing expenses
decreased from 49% in 1997 and 1998 to 48% in 1999.

Product Development. Product development expenses increased from $18,081,000 in
1997 to $20,862,000 in 1998 and to $24,983,000 in 1999 (net of the effect of
capitalized software development costs of $1,564,000 in 1997, $1,933,000 in 1998
and $2,593,000 in 1999) an increase of 15% in 1998 and an increase of 20% in
1999. In the same periods, the Company's expense for amortization of capitalized
software and product translations, included in cost of revenues was $1,703,000
in 1997, $1,892,000 in 1998 and $3,182,000 in 1999. The increases in product
development expenses were primarily due to staff increases, salary increases and
recruiting fees. As a percentage of net revenues, product development expenses
increased from 16% in 1997 to 17% in 1998 and to 18% in 1999.

General and Administrative. General and administrative expenses decreased from
$12,283,000 in 1997 to $9,427,000 in 1998 and increased to $9,773,000 in 1999, a
decrease of 23% in 1998 and an increase of 4% in 1999. The decrease in 1998 was
primarily attributable to reductions in costs and personnel in the acquired
Clear, Jandel, and Quantime entities. The increase in 1999 was due to additional
administrative staff, primarily information systems personnel. This expense
decreased as a percentage of net revenues from 11% in 1997 to 8% in 1998 to 7%
in 1999.

Special General and Administrative Charges. Special general and administrative
charges related to the write-off of certain assets in connection with
integration procedures associated with the acquisitions of DeltaGraph, Quantime,
and In2itive were $5,616,000 in 1997. SPSS evaluated the fair value of assets
recorded through prior acquisitions and identified certain intangible assets
which had no future value. The respective balances of these assets were written
off during 1997. SPSS also re-evaluated the fair value of assets acquired
through prior acquisitions and identified certain intangible assets which had a
reduced future value. The respective balances of these assets were also written
down during 1997. Special general and administrative charges were $445,000 in
1998 and represented the write-off of duplicate capitalized software development
costs on platforms such as UNIX and Open VMS products as a result of the
acquisitions of Surveycraft and Integral Solutions.

Merger-related. SPSS incurred merger-related costs of $4,306,000 in 1997,
$1,948,000 in 1998 and $1,611,000 in 1999 related to acquisitions accounted for
as poolings of interests, which costs include professional fees, employee
severance payments, facility costs and various other expenses. SPSS incurred
merger-related costs of $1,948,000 in 1998 related to acquisitions accounted for
under the purchase method, which costs include employee sign-on bonuses,
employee severance, facility costs, and various other expenses. Included in
these costs is a charge for the consolidation of the Company's United Kingdom
facilities of $1,307,000 in 1997 and a recovery of $280,000 in 1998 when the
plan was revised based on the acquisition of Integral Solutions. The United
Kingdom facility consolidation plan



                                       24
<PAGE>   25

was established to achieve cost efficiencies through the elimination of
redundant facilities and includes accruals of $526,000 for estimated lease
charges, $286,000 for estimated property tax charges, $207,000 for the write-off
of leasehold improvements and $8,000 for dilapidation charges. The United
Kingdom facility consolidation plan was revised in 1999 when SPSS was unable to
secure suitable facilities in a competitive London real estate market. This led
to a recovery of $803,000 in 1999. Included in 1999 merger-related costs were
expenses related to management and sales force restructuring, employee sign-on
bonuses, professional fees, and various other expenses.

Acquired In-Process Technology. Acquired in-process technology costs were
$421,000 in 1997 and related to an acquisition of a software product from
DeltaPoint. Acquired in-process technology costs were $3,552,000 in 1998 and
related to the acquisitions of Surveycraft and Integral Solutions accounted for
under the purchase method. Acquired in-process technology costs were $128,000 in
1999 and related to an acquisition of the VerbaStat software product from
DataStat.

In November 1998, SPSS acquired all of the outstanding capital stock of
Surveycraft, a provider of market research software in the Pacific Rim. A
portion of the purchase price was attributable to acquired in-process
technology, as the development work associated with the project had not reached
technological feasibility and was believed to have no alternative future use
other than as market research software. SPSS carefully assessed the fair value
of the acquired in-process technology using an income approach. Future cash
flows were projected over five years discounted to present value using a
discount rate of 18%. SPSS believes the discount rate is appropriate given the
level of risk of unsuccessful completion of the technology as it was estimated
to be approximately 85% complete, both in terms of costs invested as of the
acquisition date relative to completion costs and technical achievements. In
projecting the future revenue streams from the project, SPSS considered many
factors including competition, market growth estimates, time to market and
additional sales and marketing leverage which SPSS could provide to the
Surveycraft products.

In December 1998, SPSS acquired all of the outstanding capital stock of Integral
Solutions, a leading provider of data mining software. A portion of the purchase
price was attributable to acquired in-process technology, as the development
work associated with several projects had not reached technological feasibility
and were believed to have no alternative future use other than as data mining
tools. SPSS carefully assessed the fair value of the acquired in-process
technology using an income approach. Future cash flows were projected over five
years discounted to present value using discount rates ranging from 34% to 37%
depending on the project and the market risks associated with each of the
research and development projects and resulting products. Specific consideration
was given to the stage of development of each research and development effort,
which ranged from 23% to 82% complete, both in terms of costs invested as of the
acquisition date relative to completion costs and technical achievements. In
projecting the future revenue streams from the projects, SPSS considered many
factors including competition, market growth estimates, time to market and
additional sales and marketing leverage which SPSS could provide to the Integral
Solutions products.

In December 1999, SPSS acquired the VerbaStat software program, a software tool
for computer aided coding of open-ended survey questions, from DataStat. A
portion of the purchase price was attributable to acquired in-process
technology, as the development work associated with the program had not reached
technological feasibility and were believed to have no alternative future use.
SPSS carefully assessed the fair value of the acquired in-process technology
using an income approach. Future cash flows were projected over five years
discounted to present value using a discount rate of 20% based on the project
and the market risks associated with the research and development project and
resulting product. Specific consideration was given to the stage of development
of the research and development effort,



                                       25
<PAGE>   26

which was 75% complete, both in terms of costs invested as of the acquisition
date relative to completion costs and technical achievements. SPSS anticipates
incurring approximately $25,000 of additional research and development costs
over a short time frame with anticipated completion date in 2000. In projecting
the future revenue streams from the project, SPSS considered many factors
including competition, market growth estimates, time to market and additional
sales and marketing and leverage which SPSS could provide to the VerbaStat
product.

Net Interest Income (Expense). Net interest income was $375,000 in 1997 and
$333,000 in 1998 primarily due to interest earned on short-term investments. Net
interest expense was ($529,000) in 1999 primarily due to interest expense
incurred on the line-of-credit.

Other Income (Expense). Other income (expense) consists mainly of foreign
exchange transactions. The foreign exchange amounts were ($488,000) in 1997,
($238,000) in 1998 and $119,000 in 1999.

Provision for Income Taxes. The provision for income taxes consisted of
$3,189,000 in 1997, $8,404,000 in 1998 and $8,621,000 in 1999. During 1997, the
provision for income taxes represented a tax rate of 44%, excluding the effect
of Japanese withholding taxes on monies transferred out of Japan in 1997, and
the non-deductibility of some Quantime expenses. During 1998, the provision for
income taxes represented a tax rate of approximately 38%, excluding the effect
of Japanese withholding taxes on monies transferred out of Japan in 1998, and
certain expenses related to the Surveycraft and Integral Solutions acquisitions.
During 1999, the provision for income taxes represented a tax rate of
approximately 36%, excluding the effect of Japanese monies transferred out of
Japan in 1999.

LIQUIDITY AND CAPITAL RESOURCES

         The Company's long-term debt as of December 31, 1999 is a mortgage on
property in the United Kingdom, and the balance of the purchase price due to
DataStat, S.A. for the acquisition of the VerbaStat product. As of December 31,
1999, SPSS held approximately $16,770,000 of cash. Funds in 1998 were used
primarily for payments related to the Company's acquisitions, as well as for
capital expenditures including, new computer systems for use in internal product
development, and leasehold improvements and furnishings for the Company's new
office space in the Sears Tower in Chicago, Illinois. Funds in 1999 were used
primarily for payments related to SPSS' acquisitions, as well as new computer
systems for use in internal product development and expenditures made for an
office move in Sweden.

         In June 1999, SPSS revised its loan agreement with American National
Bank and Trust Company of Chicago. Under the new loan agreement, SPSS has an
available $10,000,000 unsecured line of credit with American National, under
which borrowings bear interest at either the prime interest rate or the
Eurodollar Rate, depending on the circumstances. As of December 31, 1999, SPSS
had $9,000,000 outstanding under this line of credit. The Company's agreement
with American National requires SPSS to comply with certain specified financial
ratios and tests, and, among other things, restricts the Company's ability to:

         o        incur additional indebtedness;

         o        create liens on assets;

         o        make investments;

         o        engage in mergers, acquisitions or consolidations where SPSS
                  is not the surviving entity;



                                       26
<PAGE>   27

         o        sell assets;

         o        engage in select transactions with affiliates; and

         o        amend its organizational documents or make changes in its
                  capital structure, and also requires SPSS to be Year 2000
                  compliant in software and other information processing
                  capabilities.

         Also in June 1999, SPSS entered into an amendment to the loan agreement
with American National. This amendment makes an additional $10,000,000 available
to SPSS for the acquisition of assets and further requires that SPSS meet all
original requirements of the loan agreement and give American National the
opportunity to use any proceeds from a public offering of equity or debt
securities to retire outstanding amounts on the line of credit.

         SPSS anticipates the amounts available from cash and cash equivalents
on hand, under its line of credit, and cash flows generated from operations,
will be sufficient to fund the Company's operations and capital requirements for
the foreseeable future. However, no assurance can be given that changing
business circumstances will not require additional capital for reasons that are
not currently anticipated or that the necessary additional capital will then be
available to SPSS on favorable terms or at all.

         The Company's capital expenditures, primarily for computer systems and
office furniture totaled approximately $4,400,000 in 1999 and are projected to
total approximately $8,500,000 in 2000 and $5,500,000 in 2001. Capital
expenditures during 2000 will include new computers, primarily for use in
internal product development, replacement of its systems for accounting and
order entry, as well as furnishings and other equipment related to the move of
the Company's facilities in Kilburn, UK, and expansion of facilities in Chicago,
Miami, Woking, UK, Denmark, and Australia. SPSS does not believe that the
implementation of its business strategy will require substantial additional
capital expenditures in comparison with historical levels of product development
costs and other expenses.

INTERNATIONAL OPERATIONS

         Significant growth in the Company's international operations also
occurred from 1995 to 1999. Revenues from international operations comprised
approximately 47% to 52% of total net revenues between 1995 and 1999. They were
approximately 50% of total net revenues in 1999.

         Following the reorganization of its international operations in 1990,
SPSS has maintained substantially the same direct sales and telesales
organizations worldwide. The international sales organization uses more
independent distributors than does the domestic sales organization, primarily in
countries without an SPSS sales office. Management believes the profit margins
associated with the Company's domestic and international operations are
essentially the same.

         As international revenues increase, SPSS may experience additional
foreign currency exchange risk. To mitigate these effects, SPSS hedges its
transaction exposure (i.e., the effect on earnings and cash flows of changes in
foreign exchange rates on receivables and payables denominated in foreign
currencies). SPSS does not hedge its foreign currency exposure in a manner that
would entirely eliminate the effects of changes in foreign exchange rates on the
Company's consolidated net income. Accordingly, the Company's reported revenues
and net income have been and in the future may be affected by the changes in
foreign exchange rates.

YEAR 2000

         The Company spent approximately $1.5 million to address issues with the
year 2000 date change. The Company has not experienced business disruption or
incurred significant expenses in 2000 related to the date change.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES OF MARKET RISKS

         The Company's market risk disclosures pursuant to item 7A are not
material and are therefore not required.

                          INDEPENDENT AUDITORS' REPORT



The Board of Directors and Stockholders
SPSS Inc.:

We have audited the consolidated financial statements of SPSS Inc. and
subsidiaries (the "Company") as listed in the accompanying index. In connection
with our audits of the consolidated financial statements, we also have audited
the financial statement schedule as listed in the accompanying index. These
consolidated financial statements and the financial statement schedule are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements and the financial statement
schedule 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 consolidated financial statements referred to above present
fairly, in all material respects, the financial position of SPSS Inc. and
subsidiaries as of December 31, 1998 and 1999, and the results of their
operations, and their cash flows for each of the years in the three-year period
ended December 31, 1999, in conformity with generally accepted accounting
principles. Also in our opinion, the related financial statement schedule, when
considered in relation to the basic consolidated financial statements taken as a
whole, presents fairly, in all material respects, the information set forth
therein.

                           SPSS INC. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         (a) Description of Business

         SPSS Inc. ("SPSS" or the "Company") is a multinational company that
provides software and professional services for discovering what customers want
and predicting what they will do. The Company's products and services,
individually and in combination, are primarily used by commercial organizations
to integrate and analyze market, customer, and operational data in the process
of formulating strategies and programs to interact with their customers more
effectively. This process is commonly called "data mining" or "data analysis
using advanced analytical techniques."

         Analytical solutions include products and services, sold separately or
in combination, for customer relationship management, business intelligence, and
business performance measurement applications. Market research includes
products and services, sold separately or in combination, for survey design,
implementation, and analysis in the market research industry. Statistics
include products and services, sold separately or in combination, for general
purpose statistical analysis.

         (b) Principles of Consolidation

         The consolidated financial statements include the accounts of SPSS Inc.
and its wholly-owned subsidiaries. All intercompany accounts and transactions
have been eliminated in consolidation.

         (c) Use of Estimates

         Management of SPSS has made a number of estimates and assumptions
relating to the reporting of assets and liabilities and the disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting periods.
Actual results could differ from those estimates.

         (d) Software Revenue Recognition

         SPSS primarily recognizes revenue from product licenses, net of an
allowance for estimated returns and cancellations, at the time the software is
delivered. Revenue from certain product license agreements is recognized upon
contract execution, product delivery, and customer acceptance.

         Revenue from postcontract customer support ("PCS" or "maintenance")
agreements, including PCS bundled with product licenses, is recognized ratably
over the term of the related PCS agreements. Some product licenses include
commitments for insignificant obligations, such as technical and other support,
for which an accrual is provided.

         Revenue from training, consulting, publications, and other items is
recognized as the related products or services are delivered or rendered.

         On January 1, 1998, SPSS adopted AICPA Statement of Position ("SOP")
97-2, Software Revenue Recognition, which specifies the criteria that must be
met prior to SPSS recognizing revenues from software sales. The adoption of SOP
97-2 in 1998 has not had a material impact on the Company's financial position
or results of operations.



                                       36
<PAGE>   37

         (e) Software Development Costs

         Software development costs incurred by SPSS in connection with the
Company's long-term development projects are capitalized in accordance with
Statement of Financial Accounting Standards ("SFAS") No. 86, Accounting for the
Costs of Computer Software to Be Sold, Leased, or Otherwise Marketed. SPSS has
not capitalized software development costs relating to development projects
where the net realizable value is of short duration, as the effect would be
immaterial. SPSS reviews capitalized software development costs each period and,
if necessary, reduces the carrying value of each product to its net realizable
value.

         (f) Earnings per Share

         In the fourth quarter of 1997, SPSS adopted SFAS No. 128, Earnings Per
Share, which established new methods for computing and presenting earnings per
share ("EPS") and replaced the presentation of primary and fully-diluted EPS.
Basic earnings per share is based on the weighted average number of shares
outstanding and excludes the dilutive effect of unexercised common stock
equivalents. Diluted earnings per share is based on the weighted average number
of shares outstanding and includes the dilutive effect of unexercised common
stock equivalents.

</TABLE>


         (g) Depreciation and Amortization

         Depreciation of buildings is provided over thirty years on a
straight-line method. Furniture and equipment is depreciated using the
straight-line method over the estimated useful lives of the assets, which range
from three to eight years. Leasehold improvements are amortized on the
straight-line method over the remaining terms of the respective leases.
Capitalized software costs are amortized on a straight-line method over three to
five years based upon the expected life of each product. This method



                                       37
<PAGE>   38

results in greater amortization than the method based upon the ratio of current
year gross product revenue to current and anticipated future gross product
revenue.

         As of January 1, 1998, SPSS adopted SOP 98-1, Accounting for the Costs
of Computer Software Developed or Obtained for Internal Use. This standard
requires that certain costs related to the development or purchase of
internal-use software be capitalized and amortized over the estimated useful
life of the software. SOP 98-1 also requires that costs related to the
preliminary project stage and post-implementation/operations stage of an
internal-use computer software development project be expensed as incurred.
During 1998 and 1999, SPSS capitalized $873,000 and $739,000 and amortized
$6,000 and $23,000, respectively, of internal-use computer software.

         (h) Income Taxes

         SPSS follows SFAS No. 109, Accounting for Income Taxes. SFAS No. 109
requires the asset and liability method of accounting for income taxes in which
deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases and operating loss and tax credit carryforwards. Deferred tax assets and
liabilities are measured using enacted tax rates expected to apply to taxable
income in the years in which those temporary differences are expected to be
recovered or settled. Under SFAS No. 109, the effect on deferred tax assets and
liabilities of a change in tax rates is recognized in income in the period that
includes the enactment date.

         (i) Stock Option Plans

         Prior to January 1, 1996, SPSS accounted for its stock option plans in
accordance with the provisions of Accounting Principles Board ("APB") Opinion
No. 25, Accounting for Stock Issued to Employees, and related interpretations.
As such, compensation expense would be recorded on the date of grant only if the
current market price of the underlying shares exceeded the exercise price. On
January 1, 1996, SPSS adopted SFAS No. 123, Accounting for Stock-Based
Compensation, which permits entities to recognize as expense over the vesting
period the fair value of all stock-based awards on the date of grant.
Alternatively, SFAS No. 123 also allows entities to continue to apply the
provisions of APB No. 25 and provide pro forma net income disclosures for
employee stock option grants made in 1995 and future years as if the fair-value
based method defined in SFAS No. 123 had been applied. SPSS has elected to
continue to apply the provisions of APB Opinion No. 25 and provide the pro forma
disclosures required by SFAS No. 123.

         (j) Inventories

         Inventories, consisting of finished goods, are stated at the lower of
cost or market. Cost is determined using the first-in, first-out method.

         (k) Goodwill

         The excess of the cost over the fair value of net assets acquired is
recorded as goodwill and amortized on a straight-line basis over 10 to 15 years.
Accumulated amortization was $793,000 and $1,331,000 as of December 31, 1998 and
1999, respectively.



                                       38
<PAGE>   39

         (l) Foreign Currency Translation

         The translation of the applicable foreign currencies into U.S. dollars
is performed for balance sheet accounts using current exchange rates in effect
at the balance sheet date and for revenue and expense accounts using the average
exchange rates during the period. The gains or losses resulting from such
translation are included in stockholders' equity. Gains or losses resulting from
foreign currency transactions are included in "other income and expense" in the
statement of income.

         (m) Fair Value of Financial Instruments

         The fair values of financial instruments were not materially different
from their carrying values.

         (n) Cash and Cash Equivalents

         Cash and cash equivalents are comprised of highly liquid investments
with original maturity dates of less than three months.

         (o) Long-Lived Assets

         Long-lived assets to be held and used are reviewed for impairment
whenever events or changes in circumstances indicate that the carrying amount
should be evaluated. Impairment is measured by comparing the carrying value to
the estimated and undiscounted future cash flows expected to result from the use
of the assets and their eventual disposition. SPSS has determined that as of
December 31, 1999, there has been no impairment in the carrying values of the
long-lived assets.

         (p) Reclassifications

         Where appropriate, some items relating to the prior years have been
reclassified to conform to the presentation in the current year.

(4) ACQUISITIONS

         In May 1997, SPSS purchased all of DeltaPoint Inc.'s assets primarily
relating to and comprising DeltaGraph computer software products for $910,000.
The transaction was accounted for as an asset purchase, and, accordingly the
acquired assets were recorded at their estimated fair market values. The $8,000
excess of the purchase price over the fair market values of the assets was
recorded as goodwill.

         In September 1997, SPSS acquired approximately 97% of the outstanding
shares of capital stock of Quantime Limited ("Quantime"), a corporation
organized under the laws of England, in exchange for 863,049 shares of Common
Stock. In November 1997, SPSS acquired the remaining shares of capital stock of
Quantime in exchange for 28,175 shares of Common Stock. The acquisition was
accounted for as a pooling of interests and, accordingly, the consolidated
financial statements have been restated as if SPSS and Quantime had been
combined for all periods presented. Quantime is a developer of market research
products.

         In November 1997, SPSS acquired the outstanding shares of capital stock
of In2itive Technologies A/S ("In2itive"), a corporation organized under the
laws of Denmark, in exchange for 140,727 shares of Common Stock in a merger
accounted for as a pooling of interests and, accordingly, the consolidated
financial statements have been restated as if SPSS and In2itive had been
combined for all periods presented. In2itive is a computer software company
specializing in market research software. SPSS will continue to operate the
In2itive business principally from the In2itive headquarters in Copenhagen,
Denmark.

         In November 1998, SPSS acquired all of the outstanding shares of
capital stock of Surveycraft Pty. Ltd. ("Surveycraft") for an aggregate purchase
price of approximately $1,700,000. The Surveycraft acquisition was accounted for
as a purchase and, accordingly, the acquired assets and liabilities have been
recorded at their estimated fair values. In the fourth quarter of 1998, SPSS
recorded charges of approximately $863,000 representing a one-time write-off of
acquired in-process technology and other merger-related costs. Surveycraft is a
computer software company specializing in market research software. In 1999 SPSS
consolidated the Surveycraft business into its Australia and Cincinnati offices.
Also in 1999, some assumed liabilities were revalued, and goodwill was decreased
by $371,000.

         On December 31, 1998, SPSS acquired all of the outstanding shares of
capital stock of Integral Solutions Limited ("Integral Solutions"), a
corporation incorporated under the laws of England, from the shareholders of
Integral Solutions (the "Shareholders"). The stock purchase occurred pursuant to
the Stock Purchase Agreement between SPSS and the Shareholders in the United
Kingdom (the "Agreement") dated as of December 31, 1998. SPSS acquired Integral
Solutions from the Shareholders for approximately $7,000,000 plus some
Contingent Payments (as defined in the Agreement) of up to approximately
$7,000,000 based on future results of the acquired business (the "Purchase
Price"). An additional payment of approximately $3,900,000 was made in January
2000. Additional payments will be recorded as an adjustment to purchase price in
the periods in which such payments are determinable. The Integral Solutions
acquisition was accounted for as a purchase and, accordingly, the acquired
assets and liabilities have been recorded at their estimated fair values. In the
fourth quarter of 1998, SPSS recorded charges of approximately $5,053,000
representing a one-time write-off of acquired in-process technology and other
merger-related costs. Integral Solutions is a leading full-service data mining
company, supplying consultancy and training. In 1999 Integral Solutions office
lease expired



                                       42

and personnel were moved to the existing SPSS UK Ltd offices in Woking, England.
Also in 1999, some assumed liabilities were revalued, and goodwill was increased
by $227,000.

         The following summary presents information concerning the purchase
price allocations for the acquisitions accounted for under the purchase method
for the year ended December 31, 1998.

         (1) Purchase price included costs associated with the acquisition and
acquired deferred tax liabilities.

         SPSS incurred significant costs and expenses in connection with these
acquisitions, including professional fees, employees' severance and various
other expenses. Such expenses were recorded as part of the purchase price in
connection with the Surveycraft and Integral Solutions acquisitions accounted
for as purchases.

         On November 29, 1999, SPSS acquired all of the outstanding shares of
capital stock of Vento Software, Inc. ("Vento"), a corporation incorporated
under the laws of Florida, from the shareholders of Vento in exchange for
546,060 shares of Common Stock in a stock acquisition accounted for as a pooling
of interests and, accordingly, the consolidated financial statements have been
restated as if SPSS and Vento had been combined for all periods presented. In
the fourth quarter of 1999, SPSS recorded charges of approximately $1,948,000
representing merger-related costs for expenses relating to management and sales
force restructuring, employee sign-on bonuses, professional fees and various
other expenses. Vento is an analytical solutions software company whose assets
include the VentoMap product line, a series of industry-specific software
products for business performance measurement, and a proprietary methodology for
the delivery of related professional services. SPSS plans to further develop
these Vento products and integrate its data mining capabilities, as well as use
the Vento professional services methodology as a basis for expanded consulting
activities supporting the implementation of its analytical solutions.

         LITIGATION

         SPSS is subject to certain legal proceedings and claims that have
arisen in the ordinary course of business and have not been adjudicated.
Management currently believes the ultimate outcome of these matters will not
have a material adverse effect on the Company's results of operations or
financial position.


(6) OTHER NON-CURRENT LIABILITIES

         SPSS has a mortgage on its freehold property which houses the SPSS
Limited offices in London, England. The mortgage is held by Norwich Union
Investment Management of Norwich, England and is a fixed 12.04%, 30-year
mortgage expiring in January 2010. The annual principal and interest payments
total British Pounds Sterling (GBP) 109,692 (approximately $177,000). The
current portion of this debt is GBP 29,453 (approximately $53,000), and is
included in "Other accrued liabilities". The non-current balance as of December
31, 1999 is GBP 575,056 (approximately $929,000).

         In December 1999, SPSS entered into an asset purchase agreement with
DataStat, S.A. for the purchase of the VerbaStat product. Under the terms of the
agreement, SPSS will pay DataStat twelve quarterly installment payments of
$83,333. The current portion of this debt is approximately $250,000, and is
included in "Other accrued liabilities."

(7) FINANCING ARRANGEMENTS

         In May 1998, SPSS entered into a loan agreement with American National
Bank and Trust Company of Chicago. Under the agreement, SPSS has an available
$10,000,000 unsecured line of credit. At December 31, 1999, SPSS had $9,000,000
in borrowings under this credit agreement. In June 1999, SPSS entered into a
second loan agreement with American National, under which SPSS has available an
additional $10,000,000 unsecured line of credit. At December 31, 1999, SPSS had
no borrowings under its second credit agreement. Borrowings against each
agreement bear

         The valuation allowance decreased $1,256,000 in 1997, remained
unchanged in 1998, and decreased $867,000 in 1999. In assessing the
realizability of deferred tax assets, management considers whether it is more
likely than not that some portion or all of the deferred tax assets will not be
realized. The ultimate realization of deferred tax assets is dependent upon the
generation of future taxable income during the periods in which those temporary
differences become deductible. Management considers the scheduled reversal of
deferred tax liabilities, projected future taxable income, and tax planning
strategies in making this assessment.

         As of December 31, 1999, Jandel had net operating loss carryforwards of
approximately $285,000 for Federal purposes, expiring in the year 2010. Due to
the merger with SPSS, Jandel's ability to utilize net operating loss
carryforwards may be affected.

         As of December 31, 1999, SPSS A/S had a Denmark net operating loss
carryforward of approximately $2,692,000, which begins to expire in 2000.

         As of December 31, 1999, SPSS had a Federal research and
experimentation credit carryforward of approximately $523,000, which begins to
expire in 2000.

(10) EMPLOYEE BENEFIT PLANS

          Effective February 1, 1995, SPSS amended its 401(k) savings plan.
Qualified employees may participate in the savings plan by contributing up to
the lesser of 15% of eligible compensation or $9,240 in a calendar year.
Beginning in 1999, SPSS made a matching contribution of $500 for employees in
the plan the entire year, which resulted in a $192,000 contribution by SPSS
recorded as compensation expense. Also in 1999, the plan year was amended to
begin on December 31 of each year and end on December 30.

          In 1993, SPSS implemented an employee stock purchase plan. The SPSS
purchase plan provides that eligible employees may contribute up to 10% of their
base salary per quarter towards the quarterly purchase of SPSS common stock. The
employee's purchase price is 85% of the fair market value of the stock at the
close of the first business day after the quarterly offering period. The total
number of shares issuable under the purchase plan is 100,000. During 1997,
11,256 shares were issued under the purchase plan at market prices ranging from
$24.25 to $29.875. During 1998, 18,663 shares were issued under the purchase
plan at market prices ranging from $19.25 to $23.75. During 1999, 18,249 shares
were issued under the purchase plan at market prices ranging from $16.75 to
$25.50. SPSS recorded $47,000, $54,000 and $52,000 in compensation expense
related to the purchase of these shares in 1997, 1998 and 1999, respectively.

(11) RESEARCH AND DEVELOPMENT LIMITED PARTNERSHIPS

         SPSS entered into agreements with limited partnerships in 1981, 1982
and 1985 to perform research and development for new and existing computer
software. Certain of the general and limited partners of these partnerships are
officers of SPSS and under these agreements, SPSS incurred royalty expense to
the partnerships of $319,000, $235,000 and $237,000, for the years ended
December 31, 1997, 1998 and 1999.

(12) STOCK OPTIONS

         On January 16, 1992, SPSS adopted a Stock Option Plan for some key
employees. Options vest either immediately or over a four-year period. In
September 1994, SPSS granted options to purchase 150,000 shares of common stock
to the principal owners of SYSTAT. In addition, in June 1995, the stockholders
of SPSS adopted the 1995 Equity Incentive Plan which authorizes the Board of
Directors,



                                       48
<PAGE>   49

under some conditions, to grant stock options and shares of restricted stock to
directors, officers, other key executives, employees and independent
contractors.

         SPSS applies APB Opinion No. 25 and related interpretations in
accounting for its plans. All options under the plans have been granted at
exercise prices not less than the market value at the date of the grant.
Accordingly, no compensation cost has been recognized for its fixed stock option
plans. Had compensation cost for the Company's stock option plans been
determined consistent with SFAS No. 123, the Company's net income available to
stockholders would have been decreased to the pro forma amounts indicated below:

         Under the stock option plans, the exercise price of each option equals
the market value of the Company's stock on the date of grant. For purposes of
calculating the compensation costs consistent with SFAS No. 123, the fair value
of each 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 fiscal 1997, 1998 and 1999, respectively; no expected dividend yield;
expected volatility of 25% in 1997 and 1998, and 39 percent in 1999; risk free
interest rates of 5.57%, 5.30% and 6.43%, respectively, and expected lives of 8
years. Additional information regarding options is as follows:

exercise price of the options by tendering by attestation SPSS common stock. In
that case, the Board could grant these "reload" options in an amount equal to
the number of shares of SPSS common stock that the option holder tendered by
attestation.

(2) In satisfaction of applicable SEC regulations, the table shows the potential
realizable values of these options, upon their latest possible expiration date,
at arbitrarily assumed annualized rates of stock price appreciation of five and
ten percent over the term of the options. The potential realizable value columns
of the table illustrate values that might be realized upon exercise of the
options at the end of the ten-year period starting with their vesting
commencement dates, based on the assumptions shown above. Because actual gains
will depend upon the actual dates of exercise of the options and the future
performance of the common stock in the market, the amounts shown in this table
may not reflect the values actually realized. No gain to the named executive
officers is possible without an increase in stock price which will benefit all
stockholders proportionately. Actual gains, if any, on option exercises and
common stock holdings are dependent on the future performance of the common
stock and general stock market conditions. There can be no assurance that the
potential realizable values shown in this table will be achieved, or that the
stock price will not be lower or higher than projected at five and ten percent
assumed annualized rates of appreciation.

(3) Options shown in the table for Mr. Durrell are options granted to Valletta.

EMPLOYMENT AGREEMENTS

         SPSS entered into an employment agreement with Jack Noonan on January
14, 1992. This employment agreement provides for a one-year term with automatic
one-year extensions unless Mr. Noonan or SPSS gives a written termination notice
at least 90 days before the expiration of the initial term or any extension. It
also provides for a base salary of $225,000 during the initial term, together
with the same benefits provided to other employees of SPSS. The Board of
Directors annually reviews Mr. Noonan's base compensation and increased it to
$235,000 for 1993, 1994, 1995, 1996 and 1997, to $242,500 in 1998, and to
$256,500 in 1999. If SPSS terminates Mr. Noonan's employment without cause, SPSS
must pay Mr. Noonan an amount equal to 50% of Mr. Noonan's annual base salary in
effect at the time of termination. This amount is payable in 12 equal monthly
installments. However, if Mr. Noonan finds other employment at a comparable
salary, the Company's obligation to make these payments ceases. The employment
agreement requires Mr. Noonan to refrain from disclosing confidential
information of SPSS and to abstain from competing with SPSS during his
employment and for a period of one year after employment ceases. Only Mr. Noonan
and Mr. Durrell, through a management services agreement with Valletta described
in "Management Services Agreement" below, are employed through an employment or



                                       58

similar agreement. However, SPSS does have confidentiality and work-for-hire
agreements with many of its key management and technical personnel.

MANAGEMENT SERVICES AGREEMENT

         SPSS has entered into a management services agreement with Valletta,
which requires that Ian Durrell's services are provided to SPSS. Either Valletta
or SPSS may terminate the agreement at any time upon 30 days' written notice. If
SPSS terminates the agreement under the 30-day notice provision without cause,
Valletta is entitled to termination payments equal to 50% of its annual
compensation then in effect in six equal monthly installments. The agreement
further provides that if specified performance standards are satisfied, Valletta
is to receive annual compensation at a rate established by the Board of
Directors plus incentive compensation. For 1999, Valletta's aggregate
compensation, including bonus, was $338,500. The management services agreement
requires Valletta to refrain from disclosing confidential information about SPSS
and to abstain from competing with SPSS during the term of the management
services agreement and for a period of eighteen months thereafter. Mr. Durrell
has agreed to be bound by the terms and conditions of the management services
agreement and to act as Vice-President, International and to head the Company's
non-western hemisphere operations.

CONSULTING AGREEMENT

         SPSS has entered into a consulting agreement, dated as of January 1,
1997, with Norman H. Nie Consulting L.L.C., an Illinois Limited Liability
Company. Nie Consulting is to provide thirty (30) hours per month of consulting
services on various matters relating to the business of SPSS. This consulting
agreement provides for a one-year term with automatic one-year extensions unless
Nie Consulting or SPSS gives a written notice of termination at least 30 days
prior to the expiration of the initial term or any extension. SPSS may terminate
this consulting agreement for cause, in which event SPSS shall pay Nie
Consulting all accrued but unpaid compensation. The agreement also provides that
Nie Consulting is to receive annual compensation of $80,800 and reimbursement of
reasonable out of pocket expenses incurred in performing services under the
consulting agreement. The consulting agreement requires that the Nie Consulting
refrain from disclosing confidential information about SPSS during the term of
the consulting agreement and for a period of five years after its expiration. In
addition, the consulting agreement requires that Nie Consulting abstain from
competing with SPSS during his consultancy and for a period of one-year after
the consultancy ceases.

CHANGE OF CONTROL AGREEMENTS

         On May 1, 1998, SPSS entered into change of control agreements with its
named executive officers. These agreements provide certain benefits to any one
or more officers who is terminated or constructively terminated following a
change of control. The agreements provide that, if the executive is terminated
without cause or constructively terminated within two years following a change
of control, then the executive may receive benefits including a severance
package equal to the greater of (a) the aggregate cash compensation received in
the immediately preceding fiscal year, or (b) two times the executive's base
salary received in the immediately preceding fiscal year; the accelerated
vesting of all previously unvested options; and participation in the same health
and welfare benefits he or she received at any time within 120 days of the
change of control for eighteen months following that date of such termination.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

         Messrs. Goldstein, Blair and Lutz were directors and members of the
Compensation Committee during the last fiscal year. None of the members of the
Compensation Committee has ever been an officer or employee of SPSS or any of
its subsidiaries.

REPORT OF THE COMPENSATION COMMITTEE

To: The Board of Directors

         The Compensation Committee of the Board of Directors is composed
entirely of directors who have never served as officers of SPSS. The
Compensation Committee develops and administers the compensation programs for
the Company's executive officers. After consideration of the Compensation
Committee's recommendations, the entire Board of Directors reviews and approves
the base salaries, bonuses and the stock option and benefit programs for the
Company's executive officers. In 1999, the Board approved the Compensation
Committee's recommendations in all material respects.

         Compensation Philosophy. SPSS has three principal objectives in its
executive compensation programs:

                  1. It strives to relate its total compensation for senior
         management to the achievement of financial benchmarks designed to build
         shareholder value.

                  2. It rewards outstanding individual performance.

                  3. It strives to structure its entire compensation package in
         a manner which is competitive with other executive compensation
         packages in the software industry, so that it will attract and retain
         highly capable key executives responsible for the success of SPSS and
         provide fair compensation for the responsibilities undertaken by those
         executives.

These goals are met through a combination of salary, bonuses, stock options and
other benefits. SPSS is committed to increasing the proportion of the senior
executives' compensation which is performance-based, and therefore variable, and
to focus on building shareholder value as the primary measure of performance. To
the extent practicable, the Compensation Committee's objective is to align the
executive officers' financial interests with those of shareholders by focusing
on specific financial objectives that the Compensation Committee believes will
enhance shareholder value and through the grant of additional options pursuant
to the Company's option plan, the opportunity for management to purchase
additional shares on advantageous terms under the Company's Employee Stock
Purchase Plan and through present stock ownership and options.

         The Compensation Committee focuses principally on the Company's
financial performance--specifically operating and net income--in determining the
amount of bonuses for the executive officers. Therefore, bonuses for these
officers are a function of the Company's overall financial performance relative
to budgeted goals. In keeping with the Company's commitment to increasing the
proportion of the senior executives' compensation which is performance-based,
base salary levels are designed to increase in comparatively small amounts and
bonus compensation is designed so that it can increase or decrease significantly
depending on the Company's overall financial performance.



                                       60
<PAGE>   61

         The Compensation Committee works with the Chief Executive Officer (the
"CEO") to determine the base salary of the other executive officers, to
establish targets for the annual bonus program and to allocate the bonus pool
among the executive officers. Consistent with the Compensation Committee's
philosophy of shifting the proportion of compensation away from fixed to
variable types of compensation, the Compensation Committee has targeted growth
in total compensation to come from the bonus and other incentive forms of
compensation. At the beginning of each year, the Compensation Committee
establishes certain budgeted objectives for operating income. The total amount
allocated to the annual bonus pool is dependent upon the degree to which
budgeted goals are achieved.

         Under the Company's Third Amended and Restated 1995 Equity Incentive
Plan, the Compensation Committee is authorized to make grants of stock options
to executive officers. The Compensation Committee normally approves grants once
a year and occasionally in connection with significant corporate events. During
1999, the Compensation Committee awarded stock options to executive officers. In
determining the size of the option grants, the Compensation Committee considers
the impact of the grants on existing shareholders' stock ownership positions and
the prospective value of the options as a performance incentive. The number of
options previously awarded to and held by executive officers is reviewed and is
one factor in determining the size of current option grants.

         The Compensation Committee has established a stock option program for
which only policy-making senior executives of SPSS are eligible. Acceleration of
the vesting of the options granted to the executive officers as of January, 1999
was contingent upon SPSS achieving certain 1999 revenue and profit levels
established by the Board of Directors. Such options are customarily granted in
the first half of the calendar year after budgetary targets have been
established. The acceleration of these options is earned only if SPSS exceeds,
by a significant percentage established by the Compensation Committee, the
budgeted performance goals for SPSS operating and net income approved by the
Board. In the event of a major corporate event, the Compensation Committee may
change these goals.

         In addition to SPSS performance, the Compensation Committee also takes
into account exceptional individual performance in determining bonus awards,
although it does not assign a specified percentage of senior executive bonus
compensation to this.

         Chief Executive Officer Compensation. The Compensation Committee also
determines the CEO's base salary and bonus, employing largely the same
principles described above, except that the amount of the CEO's bonus is purely
a function of the financial performance of SPSS measured against the operating
and net income goals established by the Compensation Committee and approved by
the Board at the beginning of each year. The Compensation Committee believes
that it has established a total compensation package which compares favorably to
industry standards. The Compensation Committee considers the total salary and
incentive compensation provided to chief executives of similar companies,
although it does not target a specific percentile range within this group of
similar companies' chief executive compensation in determining the CEO's
compensation.

         The Compensation Committee recommends stock option grants reflecting
the importance of Mr. Noonan's contribution to SPSS and the importance of
aligning Mr. Noonan's interest in SPSS with that of stockholders. In 1999, Mr.
Noonan received twice the number of stock options received by the other
policy-making senior executives. The Compensation Committee recommended grants
to Mr. Noonan of stock options to acquire 50,000 shares of common stock at
$20.50 per share effective January 4, 1999. These options vest in the same
manner as the stock options for the other senior executives.



                                       61
<PAGE>   62

         Mr. Noonan's bonus is determined in the same manner as the other
policy-making senior executives, except that no portion of Mr. Noonan's bonus is
based on exceptional individual performance. It is the Compensation Committee's
view that the CEO's compensation should be based solely on the financial
performance of SPSS and that, for the CEO, exceptional individual performance is
so closely aligned with SPSS financial performance that the CEO's bonus should
be based solely on overall SPSS financial performance.

         Tax Considerations. To the extent readily determinable and as one of
the factors in its consideration of compensation matters, the Compensation
Committee considers the anticipated tax treatment to SPSS and to the executive
officers of various payments and benefits. Some types of compensation payments
and their deductibility (e.g., the spread on exercise of non-qualified options)
depend upon the timing of an executive's vesting or exercise of previously
granted rights. Interpretations of and changes in the tax laws and other factors
beyond the Compensation Committee's control also affect the deductibility of
compensation. For these and other reasons, SPSS will not necessarily and in all
circumstances limit executive compensation to the amount which is permitted to
be deductible as an expense of SPSS under Section 162(m) of the Internal Revenue
Code. The Compensation Committee will consider various alternatives to
preserving the deductibility of compensation payments and benefits to the extent
reasonably practicable and to the extent consistent with its other compensation
objectives.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

TRANSACTIONS WITH NORMAN NIE

         Dr. Nie received 5,000 options for his services as Chairman of the
Board in 1999 and $80,800 for product development work on a part-time basis. Dr.
Nie is a limited partner in Computer Software Development Company, a research
and development limited partnership to which SPSS incurred royalty expense of
$249,000 in 1997, $234,000 in 1998 and $237,000 in 1999.

STOCKHOLDERS AGREEMENT

         In connection with the Company's initial public offering, SPSS and the
individuals and entities who were stockholders before the initial public
offering entered into an agreement containing registration rights with respect
to outstanding capital stock of SPSS and granting to each of the Nie Trust and
Morgan Stanley Venture Capital Fund, so long as they own beneficially more than
12.5% of the capital stock of SPSS, the right to designate one nominee (as part
of the management slate) in each election of directors at which directors of the
class specified for the holder are to be elected. Since the completion of the
February 1995



                                       65
<PAGE>   66

offering, Morgan Stanley Venture Capital Fund owned less than 12.5% and
currently owns no capital stock of SPSS. Currently, the Nie Trust owns less than
12.5% of the Capital Stock of SPSS.

         As required by the stockholders agreement, the holders of restricted
securities constituting more than seven percent of the outstanding shares at any
time may require SPSS to register under the Securities Act all or any portion of
the restricted securities held by the requesting holder or holders for sale in
the manner specified in the notice. SPSS is not bound to honor the request
unless the proceeds from the registered sale can reasonably be expected to
exceed $5,000,000. SPSS estimates that the cost of complying with demand
registration rights would be approximately $50,000 for a single registration.

         All of the stockholders who acquired their shares before the initial
public offering have piggyback registration rights, which entitle them to seek
inclusion of their common stock in any registration by SPSS, whether for its own
account or for the account of other security holders or both (except with
respect to registration on Forms S-4 or S-8 or another form not available for
registering restricted securities for sale to the public). In the event of a
request to have shares included in a registration statement filed by SPSS for
its own account, the Company's underwriters may generally reduce, pro rata, the
amount of common stock to be sold by the stockholders if the inclusion of all
such securities would be materially detrimental to the Company's offering.
