ITEM 1. BUSINESS
 
   The discussion below contains certain forward-looking statements [as such
term is defined in Section 21E of the Securities Exchange Act of 1934, as
amended (the "Exchange Act")] that are based on the beliefs of the management
of PLATINUM technology International, inc. and its subsidiaries (collectively,
the "Company" or "PLATINUM"), as well as assumptions made by, and information
currently available to, the Company's management. The Company's actual growth,
results, performance and business prospects and opportunities in 1999 and
beyond could differ materially from those expressed in, or implied by, such
forward-looking statements. See "Item 7. Management's Discussion and Analysis
of Financial Condition and Results of Operations--Special Note Regarding
Forward-Looking Statements" on page 33 for a discussion of risks, uncertainties
and other factors that could cause or contribute to such material differences.
 
Company Overview
 
   The Company develops, markets and supports software products, and provides
related professional services, that help organizations manage and improve their
information technology ("IT") infrastructures, which consist of all the data,
systems and applications that are used to run businesses. The Company's
products and services help IT departments, primarily in large and data
intensive organizations, minimize risk, improve service levels, and leverage
information to make better business decisions. The Company's products typically
perform fundamental functions, such as automating operations, maintaining the
operating efficiency of systems and applications, and ensuring data access and
integrity. They help organizations operate and manage large, complex,
distributed environments containing multiple computing platforms, database
management systems, applications, and operating systems that span mainframe,
midrange, and PC/LAN computing environments, including MVS, UNIX, Windows, and
Windows NT. The Company's products also support multiple database management
systems, such as the DB2 family, Oracle, Sybase, Microsoft SQL Server, UDB, and
Informix. In addition, the Company's products provide support for packaged
applications such as SAP, PeopleSoft, Baan, and Oracle Financials.
 
Market Overview
 
   Companies today rely on their IT infrastructures to keep their businesses
operating efficiently. As organizations have moved from host-based computing
systems to open systems environments, the deployment, management, maintenance
and productive use of IT has become increasingly complex. These open computing
environments service numerous end-users spread across various locations and
consist of a diverse set of applications, computing platforms (including
mainframes, minicomputers, workstations and desktop PCs/LANs), relational
database management systems ("RDBMSs"), operating systems (including UNIX,
Windows, Windows NT, and MVS) and media, including intranets and the Internet.
These open environments are also dynamic; users, as well as hardware and
software resources, are frequently added, removed or changed; and new, mission-
critical applications are continually being developed and deployed. The Company
believes that, due to the complexities of these new computing environments,
organizations are increasingly seeking to purchase IT management products and
services from a smaller number of vendors that can provide complete, flexible
and integrated solutions for managing and improving the IT infrastructures that
run their businesses.
 
Company Structure
 
   The Company's 1998 structure consisted of four business units focused on
product development and marketing and the Global Consulting Organization, a
business unit focused on providing consulting and education services worldwide.
The Company's four product business units were Database Management, Systems
Management, Application Infrastructure Management, and Data Warehousing and
Decision Support.
 
 
                                       2
<PAGE>
 
   In the first quarter of 1999, the Company replaced its existing product
business units with two core business units: Enterprise Management and
Application Lifecycle & Knowledge Management. The Company's Database Management
and Systems Management business units were merged to create the new Enterprise
Management business unit, which focuses on three key product lines: DB2
solutions, PLATINUM ProVision, and Security. The Company's Application
Infrastructure Management, and Data Warehousing and Decision Support business
units were merged to create the new Application Lifecycle & Knowledge
Management business unit, which focuses on three key product lines: ADvantage,
End-to-End Data Warehousing, and TransCentury. The Company's Internet Commerce
division is currently being folded into its Application Lifecycle & Knowledge
Management business unit.
 
   The Company consolidated its offerings into these two business units in
order to capitalize on its strengths and align more closely with customer
needs. This new structure is designed to better enable the Company to address
the two critical factors facing companies today: driving operational efficiency
by ensuring high-performance and availability of the systems that run the
business day in and day out (Enterprise Management); and driving the business
forward by delivering new applications and leveraging information (Application
Lifecycle & Knowledge Management).
 
   See Note 17 of the Notes to Consolidated Financial Statements included
elsewhere herein for further information regarding the Company's segment and
geographic information.
 
Product Strategy
 
   The Company is focused on delivering products and services that offer
customers maximum flexibility and functionality, while addressing the
increasing demand for simplified vendor relationships by building complete
solutions to IT problems. Through a combination of an aggressive acquisition
program and vigorous internal product development efforts, the Company
assembled the core competencies needed to create complete infrastructure
management solutions. Devoting substantial resources to integrating its
products and technologies, the Company is now leveraging the breadth of its
product lines and its professional services capabilities to provide complete,
customized solutions for IT infrastructure problems. These solutions include
product suites, which are sets of integrated products drawn together from
multiple product lines of the Company; point (stand-alone) products; and
product bundles, which are sets of software tools that are packaged together
but do not necessarily have the level of integration that defines a suite. The
Company also offers a wide array of professional services, including
consulting, systems integration, and educational and certification programs,
both in conjunction with and independent of software product sales.
 
   The Company's product suites provide complete solutions to companies' IT
infrastructure problems, eliminating the need for them to license single
products from many different vendors. The Company's products are designed to
permit a customer to either purchase prepackaged integrated suites or to choose
individual products and later add other products as needed. The cornerstone of
the Company's integration efforts is a set of shared components that give the
Company's products a common look and feel, common installation and
distribution, and common communication, data and events handling. Integration
components are built into individual products so that, as customers purchase
additional Company products, the newly acquired and previously installed
products can begin working together immediately.
 
   These integrated product offerings allow businesses to experience
comprehensive benefits without having to deal with multiple products or
multiple vendors. The Company has designed product suites that address IT
infrastructure problems that are shared by businesses from various industries,
as well as product suites that target IT infrastructure problems that are
unique to specific industries. For example, in early 1998, the Company began
shipping its ProVision suite of integrated tools for enterprise management,
which is the Company's most significant integrated offering of products to
date. ProVision enables companies to manage applications, databases, networks,
servers, and the Internet in an integrated fashion, providing capabilities for
job management, performance management and analysis, database administration,
database backup and recovery, security, and software distribution.
 
                                       3
<PAGE>
 
   The Company is also creating solutions for the needs of specific industries,
as well as general business needs. For example, during 1996, the Company
released PLATINUM RiskAdvisor, a data warehouse decision support application
developed specifically for the insurance industry. The Company is also enabling
its products and suites for application with Enterprise Resource Planning
(ERP), E-Commerce, and Internet/intranet/web and offers a broad set of
solutions for the Year 2000 problem. Additionally, in late 1996, the Company
formed specialty consulting practice groups within its professional services
business unit, including groups dedicated to Year 2000 solutions and
Internet/intranet technologies.
 
   Evidencing the increasing demand from the Company's customers for these
comprehensive solutions, the Company completed 147 transactions of over $1
million during 1998, as compared to 102 such transactions during 1997 and 55
such transactions during 1996. Each of these large transactions included
licenses for software product suites or bundles, along with future upgrades and
maintenance; software consulting services; or both product licenses and related
consulting services.
 
Business Units and Product Lines
 
   The Company currently develops and markets software products through its two
business units: Enterprise Management and Application Lifecycle & Knowledge
Management.
 
 Enterprise Management
 
   The Company has merged its Database Management and Systems Management
business units to create the new Enterprise Management business unit, which is
focused on three key product lines: DB2 solutions, PLATINUM ProVision, and
Security. This new structure consolidates the Company's ProVision product
development and marketing efforts, which is expected to accelerate product
delivery and streamline interaction and support for the sales organization.
 
  DB2 Product Line
 
   The Company provides a leading set of tools and utilities for DB2 database
management, including backup and recovery, database administration, database
design, and performance analysis. By automating administrative and maintenance
tasks, these software solutions enable users to achieve the highest performance
levels possible, increase data availability, automate arduous administrative
tasks while eliminating human error, and deliver new products or enhancements
to end-users faster and with more flexibility. Principal DB2 product sets
include the following:
 
  . PLATINUM Catalog Facility (PCF)--a complete set of tools that automates
    and streamlines the DBA's day-to-day tasks, reducing human error while
    keeping complete control of the database environment in the DBA's hands.
    PCF enables DBAs to automate DB2 object and data migrations; incorporate
    changes from DB2 test environments into production environments; manage
    the physical structure of databases; and manage DB2 security privileges.
 
  . Performance Analyzers--a complete set of tools that companies can rely on
    for start-to-finish performance analysis of their DB2 applications and
    systems. Capabilities include advanced analysis for monitoring and
    maintaining efficient SQL; analysis of DB2 subsystem performance and
    resource use; and database monitoring, analysis, forecasting, and tuning.
 
  . DB2 Fast Utilities--a complete set of utilities that enable DBAs to
    perform routine tasks substantially faster than can be done with native
    DB2 utilities. These tools maximize data availability to increase system
    performance and provide substantial savings in system resources, such as
    CPU and disk space.
 
  ProVision Product Line
 
   The Company offers a modular, integrated suite of tools for enterprise
management that enables companies to streamline management of applications,
databases, networks, and servers. ProVision enables
 
                                       4
<PAGE>
 
companies to reduce the costs and risks associated with managing their IT
infrastructures, while improving service levels, availability, and
productivity. ProVision's management disciplines include job management,
performance management and analysis, database administration, database backup
and recovery, security, and software distribution. Because integration is built
into each ProVision tool, organizations can implement one or more tools, and
add more tools as needed, to solve their most immediate IT problems. ProVision
began shipping in early 1998. Principal ProVision disciplines include the
following:
 
  . Automated Operations--tools that simplify management and monitoring of
    multiple jobs in distributed environments, providing centralized control
    of job execution across heterogeneous platforms and flexible features,
    such as self-correcting job control and automated restart and recovery
    capabilities.
 
  . Enterprise Performance Management--tools for monitoring, managing, and
    improving the performance of applications, databases, networks, servers,
    and the Internet. These tools enable organizations to proactively
    increase system availability, reduce downtime, and improve service levels
    enterprise-wide.
 
  . Open Systems Database Utilities--utilities for open systems databases
    (e.g., Oracle, Sybase, Microsoft SQL Server, and Informix) that
    accelerate routine database maintenance tasks, such as loads and database
    reorganizations, quick extraction of data from databases, and
    optimization of database structures.
 
  Security Product Line
 
   The Company offers AutoSecure, a complete portfolio of security products
that helps organizations manage risk within their IT infrastructures,
addressing all aspects of the IT environment that need to be protected,
including networks, servers and workstations, users, applications and services,
and information and data. AutoSecure protects information by preventing
unauthorized access to data and system resources in distributed environments;
provides single sign-on for users to applications and services they are
authorized to use, whether they are on mainframes, distributed systems or PCs;
and provides a single point for user registration in other security systems.
 
 Application Lifecycle & Knowledge Management
 
   To help customers quickly adapt applications and access information to
create competitive advantage, the Company has merged its Application
Infrastructure Management and Data Warehousing and Decision Support business
units to create the new Application Lifecycle & Knowledge Management business
unit, which is focused on three key product lines: ADvantage, End-to-End Data
Warehousing, and TransCentury. This consolidation helps the Company leverage
synergistic solutions and capabilities, such as data modeling (ERwin) and
metadata management (Repository) technologies, which support both application
development and data warehousing customers. For example, while ERwin is
integral to the Company's data warehouse solutions, especially with its
integration into DecisionBase, it is also core to the Company's ADvantage
offering. Likewise, the Company's Repository initiative with Microsoft is as
important to its ADvantage solution as it is to its Data Warehousing solution.
 
  ADvantage Product Line
 
   The Company offers ADvantage, an integrated suite of tools which provides an
application development infrastructure that enables organizations to deliver
applications on time and on budget. ADvantage helps organizations automate and
improve the processes for building, managing and delivering applications. These
products include tools for integrated project and process management, data and
component modeling, construction, testing, application deployment and software
distribution, integrated change and configuration management, and decision
support. These products facilitate the development of sophisticated, high-
performance applications and improve the overall productivity and quality of
development efforts. Principal ADvantage products include the following:
 
  . Modeling--tools that help organizations build strong information
    technology architectures by defining business processes and creating
    "blueprints" of application and data requirements and their
 
                                       5
<PAGE>
 
   relationships. These tools enable organizations to more easily reuse and
   share data and application components, and improve communication between
   business and development teams.
 
  . Change Management--tools that help development staff track and manage
    changes when building large, distributed application systems. By
    synchronizing development activities across heterogeneous platforms and
    MVS throughout the application development lifecycle, these change
    management tools help ensure more successful projects.
 
  . Decision Support for Application Development--a decision-support tool
    (ADvisor) that helps IT executives and development managers minimize the
    risks and costs associated with the applications that run their
    businesses by providing the information needed to ensure on-time, on-
    budget delivery of applications. ADvisor delivers the critical project
    information organizations need to manage application development as a
    core business process.
 
  End-to-End Data Warehousing Product Line
 
   The Company offers an integrated set of solutions for all major data
warehousing functions, including data transformation and movement, data
warehouse management, metadata management and repository, and decision support.
The Company plans to leverage and reposition these products to address the
emerging demand for knowledge management solutions. The Company's data
warehousing products help organizations build, manage and maintain data
warehouses. A data warehouse is a data store that gives end-users full access
to periodically consolidated, historical data for making business decisions and
analyzing trends without jeopardizing the performance of mission-critical
operations. Warehousing tools can capture data in many forms on numerous
platforms, transfer it to multiple database platforms and provide users with
the means to access and manage such information. Repository tools play a key
role in data warehouses as places for centralized control and as collection
points for status information concerning the warehouses and their activities.
 
   The Company's products enable organizations to better leverage their
corporate data investments by allowing end-users to derive maximum value and
insight from information. These products ensure enterprise-wide data access and
enable complex data analysis and reporting so that users can effectively
identify business trends and make informed decisions. Principal data warehouse
products include the following:
 
  . DecisionBase--a tool for metadata-based data extraction, transformation,
    and movement that enables companies to build data marts and data
    warehouses fast and maintain them easily, without sacrificing future
    flexibility. It combines graphical mapping with sophisticated
    transformation and movement capabilities and seamless integration with
    the industry-leading repository technology, which provides a common
    storage place for all enterprise-wide metadata. This single source
    ensures data consistency across the organization.
 
  . Repository--serves as a central point of control, enabling organizations
    to easily manage, maintain and access vast amounts of corporate data,
    applications, and systems in a heterogeneous environment. Repository
    provides information such as where data is located, who created and who
    maintains data, what application processes the data drives, and what
    relationship the data has with other data.
 
  . Decision Support Solutions--tools and applications that meet the decision
    support needs of business users and IT, while enabling organizations to
    build an architecture that adapts to future growth and change. Solutions
    include powerful tools for rapidly building custom decision support
    applications; tools that provide advanced online analytical processing
    (OLAP) capabilities for data warehouse environments; and business
    applications that are ready to use.
 
  TransCentury Product Line
 
   The Company offers TransCentury, an end-to-end "find-it, fix-it, test-it"
solution to the computing problem created by the Year 2000 date change.
TransCentury Year 2000 solutions cover compliance efforts from start to finish,
from mainframes to desktops. TransCentury also helps companies more effectively
plan
 
                                       6
<PAGE>
 
resources and reduce the costs and time associated with addressing the Year
2000 problem. TransCentury combines tools and technologies made available
through internal development, acquisitions, and marketing agreements.
 
  Internet Infrastructure
 
   The Company's Internet Commerce division is currently being folded into its
Application Lifecycle & Knowledge Management business unit. Raveler, the
Company's complete Internet infrastructure solution, is a set of products that
assists companies in the creation, deployment, and management of web content.
It is a content management system for sophisticated enterprise-wide web
implementations that integrates web operations into existing IT
infrastructures. Raveler gives managers a "bird's-eye" view of the status of
web projects for internal, external, or customer use. IT professionals can
automate thousands of tasks, including server uploads. From their desktops,
content creators can protect intellectual property by automatically versioning,
distributing, displaying, testing, and sharing their work with authorized co-
workers.
 
Professional Services
 
   As part of its strategy to provide complete solutions for Global 10,000 IT
organizations, the Company's Global Consulting Organization offers a range of
professional services, including consulting services, systems integration, and
educational and certification programs, in support of, and independent of, its
products. These services help businesses plan, construct and manage
infrastructures in which complex software products can be used. These services
can improve and accelerate customization, implementation and deployment of the
Company's software products. The Company believes that more rapid and effective
implementation of its software products will lead to increased customer
satisfaction and greater follow-on sales. For these reasons, the Company is now
packaging professional services as a standard feature of its product sales. As
of March 15, 1999, the Company employed approximately 1,610 persons in
professional services.
 
   Consulting Services. The Company is focusing significant effort on
developing and expanding its consulting services group. Primarily developed
through recent acquisitions of consulting services companies, this group
provides consulting services that help Global 10,000 companies manage risks,
manage the implementation of new technologies and products, and optimize their
current computing environments. Areas of expertise span systems and database
and systems management, information management, security, Year 2000
reengineering, application lifecycle management, Internet/intranet development,
and electronic commerce. The Company's consultants provide flexible,
customizable solutions as well as prepackaged solutions. They can serve all of
an organization's software consulting needs, from strategy and organization to
implementation.
 
   Educational Programs. The Company believes that its training and education
services play an important role in increasing market awareness of its software
products among IT personnel, including application developers, database
administrators and end-users. Offering a comprehensive curriculum that supports
leading technologies, the Company conducts a set of training courses designed
to deal with the critical issue of skills management. These courses cover
several key technology areas of IT infrastructure management and are held at
various training centers in the United States and throughout the Company's
international operations. The Company also offers professional certification
training, on-site computer-based training courses and self-led Internet-based
training courses that users may complete in their own offices or homes.
 
Product Development
 
   The Company pursues its product development strategy by various means,
including internally developing new software products and product enhancements,
and forming alliances with leading technology companies. Additionally, the
Company has in the past acquired, and may in the future acquire, products,
technologies and businesses complementary to the Company's existing product
lines. The Company has formed separate in-house development teams to
efficiently integrate acquired products and technologies into existing product
lines. During 1996, 1997 and 1998, product development and support expenses of
the Company were $170,145,000,
 
                                       7
<PAGE>
 
$203,497,000 and $242,641,000, respectively. As of March 15, 1999, the Company
employed approximately 1,980 persons in product development and support.
 
   Internal Development. The Company will continue to rely on the internal
development of products to expand its product lines. The Company believes its
expertise and experience give it a competitive advantage in developing products
that address increasingly complex environments and that meet evolving customer
needs. In order to fully exploit acquired software development personnel, and
to access new sources of talent, the Company has established approximately 37
independent development facilities. These development facilities are
interconnected via video conferencing, e-mail, Lotus Notes and other
communication technologies, and use various hardware, operating systems and
database systems which give the Company the ability to simulate the
environments of its customers. These facilities have responsibility for their
products and receive guidance from the Company's Chief Technology Office and
business unit management teams to foster interoperability.
 
   Technology Relationships. To reinforce its commitment to providing
interoperable solutions for managing IT infrastructures, the Company has
implemented its PLATINUM Partners Program, whereby the Company has established
strategic and technology relationships with other leading IT vendors. The
Company believes that in order to provide solutions for heterogeneous computing
environments, it will need to continue to establish and maintain key
relationships with leading technology companies. The Company's current partners
include IBM, Hewlett-Packard, Oracle, Microsoft, SAP, and Peoplesoft. These
technical and marketing alliances provide the Company early access to product
information and pre-release software.
 
   Acquisitions. The Company has in the past reviewed, and may in the future
review, acquisition candidates with leading-edge products and technologies that
could enhance the Company's product portfolio. The technologies associated with
the products of the previously acquired businesses are being incorporated into
the Company's existing internally developed products and are being used in
developing new products. In addition to providing the Company with new products
and technologies, these acquisitions have provided the Company with experienced
teams of product developers who now staff the Company's independent development
facilities. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations--Results of Operations--Costs and Expenses--Merger
Costs," "--Acquired In-Process Technology" and "--Recent Developments."
 
Product Licenses
 
   The Company provides its software products to customers under non-exclusive,
non-transferable license agreements (including standard shrink-wrap licenses
for certain products). As is customary in the software industry, in order to
protect its intellectual property rights, the Company does not sell or transfer
title to its software products to customers. Under the Company's current
standard form license agreement, licensed software may be used solely for the
customers' internal operations and only on designated hardware at specified
sites, which may be comprised of a stand-alone computer, a single network
server with multiple terminals or multiple network servers with multiple
terminals.
 
   Licenses for the Company's software are almost exclusively perpetual,
although annual and monthly licenses are also offered. License fees may be due
upon execution by the customer of the applicable product agreement or may be
payable over time for contracts involving multi-year commitments for
maintenance and product upgrades. List prices are based upon the size of the
processor, number of servers and/or number of users, depending upon the type of
license and product being licensed. The Company's published list prices include
discounts for suite, enterprise and multi-site licenses. Licenses generally
include more than one product. Under the Company's current standard form
license agreement, maintenance is renewed on an annual basis by the customer
paying the current maintenance fee. See "Technical Support and Maintenance."
 
Sales and Marketing
 
   The Company employs a multi-faceted sales strategy. For software products,
the Company utilizes telemarketers, an inside sales force, an outside sales
force, product seminars, user group participation, direct

mail, print and web-based advertising, and web promotions. The Company also
utilizes certain indirect sales channels, such as distributors, VAR and OEM
relationships for selected products.
 
   Domestic (U.S.) Software Sales. Since January 1, 1997, the Company has
organized its domestic direct sales force by regions throughout the United
States. The Company formerly combined the domestic and Canadian sales forces to
represent the North American sales force. As of March 15, 1999, the Company had
approximately 580 domestic direct sales representatives.
 
   Generally, for domestic software product licenses, the Company's
telemarketing specialists call prospective customers to identify and qualify
leads. Once a lead has been qualified, the prospective client is turned over to
the inside sales force, which predominantly supports the direct sales force by
developing sales leads and arranging product evaluations. Established sales
leads are then typically forwarded to the direct sales force, which visits
customer sites to assist with trials, demonstrate product features and close
sales transactions. For certain sales to smaller customers, as well as the
licensing of standard shrink-wrap products, the inside sales force may handle
the full sales cycle for completing such transactions.
 
   International Software Sales. The Company generally markets its products
overseas through a network of wholly-owned subsidiaries. Generally, these
subsidiaries use an approach similar to that used by the Company domestically.
As of March 15, 1999, the Company had approximately 275 international (non-
U.S.) direct sales representatives and had subsidiaries in Australia, Austria,
Belgium, Brazil, Canada, China, Denmark, Finland, France, Germany, Greece, Hong
Kong, Indonesia, Italy, Japan, Korea, Malaysia, Mexico, the Netherlands,
Norway, Philippines, Portugal, Singapore, South Africa, Spain, Sweden,
Switzerland, Taiwan, Thailand, United Arab Emirates, and the United Kingdom.
The Company expects that it will establish other foreign subsidiaries in the
future to meet its strategic objectives. The Company also markets its products
through independent distributors in Argentina, Chile, Colombia, Egypt, India,
Israel, Lebanon, Peru, Saudi Arabia, Turkey, Uruguay, and Venezuela.
 
   Global Accounts. The Company now designates certain large, geographically
dispersed entities as "global accounts." Each of these accounts is managed, on
a worldwide basis, by a single executive who focuses his or her attention on
the diverse needs of the enterprise.
 
   Professional Services. The Company's direct software sales force is
complemented by a specialized direct sales force, which specializes in
consulting services and educational programs.
 
   User Group Leadership. The Company believes that its sales and marketing
efforts have also been greatly enhanced by participation in domestic and
international user groups. The Company plays a major role in the activities of
the International DB2 Users Group, the International Oracle Users Group, the
International Sybase Users Group and other smaller user groups, and expects to
continue to do so in the future.
 
Technical Support and Maintenance
 
   The Company's in-house technical support group, situated at various sites
throughout the U.S., provides pre-sale, installation and post-sale support,
including toll-free telephone support during regular business hours, to current
users and potential customers evaluating the Company's products. The technical
support group also offers seven-day, 24-hour toll-free telephone service for an
additional fee. The Company believes that effective technical support during
product evaluation substantially contributes to product acceptance and that
post-sale support has been, and will continue to be, a substantial factor in
customer satisfaction.
 
   The Company offers a maintenance program for its software products, which
consists of product enhancements, updated products and technical support.
Maintenance is typically provided without additional charge during the warranty
period defined in the Company's license agreements. Under the Company's
standard license agreement, customers renew maintenance support on an annual
basis by paying the current maintenance fee. Customers may also commit for
maintenance and product support over extended periods of time.

Competition
 
   The Company operates in highly competitive markets and expects competition
to increase. The Company's competitors include relational database, systems
software, application development, and data warehousing vendors. However, the
Company believes that none of its competitors compete in all of the Company's
markets, which include data, systems and applications. The Company believes
that organizations are increasingly seeking to purchase IT management products
and services from a smaller number of vendors that can provide complete,
flexible and integrated solutions for managing and improving organizations' IT
infrastructures. Many of the Company's current and prospective competitors have
significantly greater financial, technical, and marketing resources than the
Company. In addition, many prospective customers may have the internal
capability to implement solutions to their IT infrastructure problems.
 
   The competitive factors affecting the market for the Company's software
products include the following: product functionality, integration, performance
and reliability; demonstrable economic benefits for users relative to cost;
quality of customer support and user documentation and ease of installation;
vendor reputation, experience and financial stability; and price.
 
   The Company believes that it has competed effectively to date and that its
ability to remain competitive will depend, to a great extent, upon its ongoing
performance in the areas of product development and customer support. To be
successful in the future, the Company must respond promptly and effectively to
the challenges of technological change and its competitors' innovations by
continually enhancing its own product offerings. Performance in these areas
will, in turn, depend upon the Company's ability to attract and retain highly
qualified technical personnel in a competitive market for experienced and
talented software developers. The Company also may continue its strategy to
acquire IT infrastructure products and technologies and businesses which have
developed such products and technologies.
 
   In addition, the Company encounters competition from a broader range of
firms in the market for professional services. Many of the Company's current
and prospective competitors in the professional services business have
significantly greater financial, technical and marketing resources than the
Company. The competitive factors affecting the market for the Company's
professional services include the following: breadth and quality of services
offered, vendor reputation and the ability to retain qualified technical
personnel.
 
Intellectual Property Rights
 
   The Company has historically relied upon a combination of contractual
rights, trademarks, trade secrets and copyright laws to establish and protect
its proprietary rights in its products. The Company also holds some patents and
believes that patents are becoming increasingly important to the software
industry. Consequently, the Company is taking actions to further protect its
proprietary rights through software patents. The Company's license agreements
restrict a customer's use of the Company's software and prohibit disclosure to
third persons. Notwithstanding those restrictions, it may be possible for
unauthorized persons to obtain copies of the Company's software products. The
Company believes that because of the rapid pace of technological change in the
computer software industry, the legal protections for its products are less
significant factors in the Company's success than the knowledge, ability and
experience of the Company's employees, the frequency of product enhancements,
and the timeliness and quality of support services provided by the Company. The
Company registers its product names and other trademarks in the United States
and certain foreign countries. The Company sells its products in foreign
countries that may afford less intellectual property rights protection than
currently afforded in the United States.
 
Employees
 
   As of March 15, 1999, the Company employed approximately 5,830 persons,
including 1,850 in sales, marketing and related activities, 1,980 in product
development and support, 1,610 in professional services, and 390 in management,
administration and finance. The Company's success is highly dependent on its
ability to
 
                                       10
<PAGE>
 
attract and retain qualified employees. Competition for employees is intense in
the software industry. None of the Company's employees is represented by a
labor union or is the subject of a collective bargaining agreement. The Company
has never experienced a work stoppage and believes that its employee relations
are good.
 
ITEM 2. PROPERTIES
 
   The Company's principal administrative, marketing, training, and product
development and support facilities are located in Oakbrook Terrace, Illinois,
where the Company leases approximately 363,000 square feet under leases
terminating in April 2003. The Company also leases approximately 175,000 square
feet of administrative, marketing, sales and product development space in
Lisle, Illinois, near the Company's headquarters, under leases terminating in
January and October 2003. In addition, the Company leases space for
approximately 122 sales offices and product development facilities throughout
the United States, ranging in size from approximately 150 to 45,000 square
feet.
 
ITEM 3. LEGAL PROCEEDINGS
 
   Computer Associates' International, Inc., and L'Agence pour la Protection
des Programmes V. La Societe Faster, S.A.R.L. (Commercial Court of Bobigny,
Paris, France). Altai, Inc. ("Altai"), a wholly-owned subsidiary of the
Company, has been involved in a suit in France concerning copyright
infringement claims identical to those on which Altai previously prevailed
against Computer Associates International, Inc. ("CAI")
in the United States. In January 1995, the French court issued a decision
rejecting CAI's claim of copyright infringement. CAI subsequently appealed this
decision to a French appellate court. In May 1998, the U.S. Supreme Court
denied Altai's petition for certiorari on motions that the U.S. court decisions
are binding with respect to the French case. On October 23, 1998, the French
appellate court upheld in all pertinent parts the decision of the French lower
court. CAI's right to appeal the decision of the appellate court expired on
March 16, 1999.
 
   The Company is also subject to certain other legal proceedings and claims
which have arisen in the ordinary course of business and which have not been
fully adjudicated. Management currently believes the ultimate outcome of such
matters and those described above will not have a material adverse effect on
the Company's results of operations or financial position.
 
ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
 
   No matters were submitted to a vote of security holders during the fourth
quarter of 1998.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
        RESULTS OF OPERATIONS
 
   The discussion and analysis below contains certain forward-looking
statements (as such term is defined in Section 21E of the Exchange Act) that
are based on the beliefs of the management of the Company, as well as
assumptions made by, and information currently available to, the Company's
management. The Company's actual growth, results, performance and business
prospects and opportunities in 1999 and beyond could differ materially from
those expressed in, or implied by, such forward-looking statements. See "--
Special Note Regarding Forward-Looking Statements" on page 33 for a discussion
of risks, uncertainties and other factors that could cause or contribute to
such material differences.
 
General
 
   The Company develops, markets and supports software products, and provides
related professional services, that help organizations manage and improve their
IT infrastructures, which consist of data, systems and applications. The
Company has two operating segments consisting of software and professional
services. Throughout 1998, the Company's software segment was organized into
four business units consisting of database management, systems management,
application infrastructure management, and data warehousing and decision
support. During the first quarter of 1999, the Company realigned its software
segment into two business units consisting of (1) enterprise management and (2)
application lifecycle and knowledge management. The Company's products and
services help IT infrastructure departments, primarily in large and data-
intensive organizations, minimize risk, improve service levels and leverage
information to make better business decisions. As an integral part of the
Company's growth strategy, it has consummated a number of significant business
combinations, some of which have been accounted for using the pooling-of-
interests method. As a result, the Company's consolidated financial statements
are presented as if the Company and such acquired companies had been
consolidated for all periods presented. Information regarding the Company in
this Management's Discussion and Analysis of Financial Condition and Results of
Operations gives retroactive effect to these acquisitions. In addition, the
Company has consummated a number of acquisitions accounted for as purchases, in
which cases the acquired businesses have been included in the Company's results
of operations beginning with the effective dates of the acquisitions.

 Revenues
 
   The Company's revenues are derived from three sources: (1) license and
upgrade fees for licensing the Company's proprietary and other parties'
software products and providing additional processing capacity on already-
licensed products, (2) maintenance fees for maintaining, supporting and
providing updates and enhancements to software products, and (3) revenues from
the Company's professional services business. Total revenues for 1998 were
$968,206,000, an increase of $229,326,000, or 31%, over 1997 total revenues of
$738,880,000. Total revenues in 1997 increased $185,396,000, or 34%, over 1996
revenues of $553,484,000.
 
 
                                       15

   The Company has a diversified customer base, with no single customer
representing greater than 10% of its total revenues generated in 1998, 1997 or
1996. The Company estimates that sales to repeat customers represented over 82%
of its revenues generated in 1998.
 
   Revenues from domestic (U.S.) customers represented 71%, 74% and 72% of the
Company's total revenues in 1998, 1997 and 1996, respectively. Domestic
revenues are generated primarily by the Company's direct sales force (which
visits customer sites to assist with trials, demonstrate product features and
close sales transactions) and inside sales force (which predominantly supports
the direct sales force by developing sales leads and arranging product
evaluations), as well as a telemarketing organization.
 
   Revenues from international customers, principally in Western Europe,
represented 29%, 26% and 28% of the Company's total revenues in 1998, 1997 and
1996, respectively. The Company generates the majority of its international
revenues through a network of wholly-owned subsidiaries, primarily utilizing a
direct sales force. Over the past two years, the Company has invested
significantly in the global marketplace, increasing its focus on international
sales efforts and expanding its international operations. For a discussion of
foreign currency exchange risk, see "--Foreign Currency Exchange Rates" and
"Item 7A. Quantitative and Qualitative Disclosures About Market Risk."
 
   The Company recognizes revenues from its software sales using the criteria
specified in the American Institute of Certified Public Accountants Statement
of Position 97-2, "Software Revenue Recognition," which was adopted on January
1, 1998. The adoption of Statement of Position 97-2 has not had a material
impact on the Company's financial position or results of operations for the
year ended December 31, 1998.
 
   The Company has continued to enter into an increasing number of higher
dollar value sales transactions with customers, primarily attributable to sales
of product bundles and integrated product suites. These transactions are
typically completed pursuant to multi-year contracts and include product
licenses, future upgrades and maintenance, sometimes also bundled with
professional services. During 1998, the Company entered into 147 sales
transactions having a total value of at least $1,000,000, of which 30 had a
total value of at least $3,000,000 and four had a total value of at least
$10,000,000. During 1997, the Company entered into 102 sales transactions
having a total value of at least $1,000,000, of which 20 had a total value of
at least $3,000,000 and three had a total value of at least $10,000,000.
 
   The table below sets forth, for the periods indicated, the Company's primary
sources of revenues expressed as a percentage of total revenues.

   Software Products. Software products revenues represented 56%, 56% and 52%
of total revenues in 1998, 1997 and 1996, respectively. In 1998, software
products revenues increased 32% to $542,578,000 from $410,369,000 in 1997, as a
result of increases of 43%, 61%, 4% and 1%, respectively, experienced by the
Company's database management, systems management, application infrastructure
management, and data
 
                                       16
<PAGE>
 
warehousing and decision support business units. From 1996 to 1997, software
products revenues increased 42% from $289,125,000 to $410,369,000. The Company
believes the growth in software products revenues over the past three years has
resulted from the continued marketplace acceptance of the Company's products
across all business units, the Company's aggressive expansion of its sales and
marketing efforts, and continuous
increases in the Company's product offerings. The increase in product offerings
has resulted in part from the acquisitions of businesses and technologies. The
substantial majority of the increases in software products revenues in 1998 and
1997 resulted from increases in the volume of sales of existing products. A
smaller, but still significant, portion of the increases related to sales of
newly introduced products, while only a small percentage was attributable to
price increases. During 1998 and 1997, the Company expanded its customer base,
increased sales of product bundles and integrated product suites, and executed
increasingly larger sales transactions. The Company's database management
(principally products relating to IBM's DB2 relational database management
software), systems management, application infrastructure management and data
warehousing and decision support business units represented 40%, 31%, 16% and
13%, respectively, of total software products revenues in 1998; 37%, 26%, 20%
and 17%, respectively, of total software products revenues in 1997; and 34%,
24%, 25% and 17%, respectively, of total software products revenues in 1996.
 
   Maintenance. Maintenance revenues in 1998 increased 23% over 1997 to
$171,711,000, and 1997 maintenance revenues of $139,912,000 represented an
increase of 22% over 1996 maintenance revenues of $114,579,000. Maintenance
revenues are derived from recurring fees charged to perpetual license customers
and the implicit first-year maintenance fees bundled in certain software
product sales. The Company provides maintenance customers with technical
support and product enhancements. Maintenance revenues are deferred and
recognized ratably over the term of the agreement. The increases during 1998
and 1997 were primarily attributable to the expansion of the Company's
installed customer base, from which maintenance fees are derived. Because
maintenance fees are implicit in certain new software product licenses, the
increase in software licensing transactions also contributed to the increase in
maintenance revenues. In 1998, the Company's database management, systems
management, application infrastructure management, and data warehousing and
decision support business units represented 39%, 23%, 20% and 18%,
respectively, of total maintenance revenues.
 
   Professional Services. Professional services revenues are associated with
the Company's consulting services business and educational programs. In 1998,
professional services revenues increased 35% to $253,917,000 from $188,599,000
in 1997. From 1996 to 1997, professional services revenues increased 26% from
$149,780,000. The growth in professional services revenues during 1998 was
primarily attributable to an increase in billable consultants, as well as a
higher ratio of billable hours to total hours worked ("utilization rate"). To a
lesser extent, increases in rates charged per billable hour, as well as
revenues associated with recently acquired consulting businesses, contributed
to this growth. The increase in professional services revenues during 1997 was
primarily due to an increase in billable consultants, as well as a higher
utilization rate. To a much lesser extent, increases in rates charged per
billable hour contributed to this growth. Additionally, the revenues generated
by the Company's new specialty consulting services practices, established near
the end of 1996, contributed to the increase in professional services revenues
during 1997.
 
 Costs and Expenses
 
   Total expenses for 1998 were $947,889,000, an increase of 13% over 1997
expenses of $841,021,000, which represented an increase of 28% over 1996
expenses of $655,093,000. Excluding restructuring charges, merger costs,
acquired in-process technology charges and special general and administrative
charges (collectively, "Special Charges"), which are discussed more fully
below, total expenses for 1998 were $869,888,000, an increase of $175,040,000,
or 25%, compared to $694,848,000 for 1997. Total expenses, excluding Special
Charges, increased 19% in 1997 as compared to $581,570,000 in 1996. Total
expenses, excluding Special Charges, represented 90%, 94% and 105% of total
revenues for 1998, 1997 and 1996, respectively. As a percentage of total
revenues, total expenses, excluding Special Charges, decreased during
 
                                       17
<PAGE>
 
1998 and 1997 due primarily to the Company's continued cost containment
efforts, as well as integration of acquisitions.
 
   Professional Services. Costs of professional services increased to
$235,914,000 in 1998, from $170,847,000 in 1997 and $145,443,000 in 1996. The
increases in these expenses during 1998 and 1997 were primarily attributable to
an increase in the number of consultants. Greater commission and bonus expenses
associated with higher professional services revenues in each year also
contributed to the increases. Costs of professional services represented 93%,
91% and 97% of professional services revenues in 1998, 1997 and 1996,
respectively. Costs of professional services in relation to professional
services revenues increased during 1998 as compared with 1997 primarily due to
less profitable Year 2000 contracts, lower than anticipated demand for the
Company's training offerings and severance costs related to international
operations. During 1997, as part of the Company's overall restructuring plan,
the Company realigned its professional services business through the
consolidation of redundant functions.
 
   Product Development and Support. Product development and support expenses
increased to $242,641,000 in 1998, from $203,497,000 in 1997 and $170,145,000
in 1996. The increases in these expenses in 1998 and 1997 were primarily
attributable to an increase in the number of product development and support
personnel from approximately 1,400 at December 31, 1996 to approximately 1,625
at December 31, 1997 and approximately 2,290 at December 31, 1998, and
increases in internal IT support costs. Product development and support
expenses represented 25%, 28% and 31% of total revenues in 1998, 1997 and 1996,
respectively. During 1997, the Company began consolidating certain product
development and support efforts to coincide with its product integration focus.
As a result of these consolidation efforts, the Company reduced product
development and support expenses as a percentage of total revenues during 1998
and 1997.
 
   In 1998, 1997 and 1996, the Company capitalized $60,343,000, $41,143,000 and
$27,246,000, respectively, of internal software development costs, net of
related amortization expense, 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." Product development and
support expenses plus capitalized internal software development costs, net of
related amortization expense, were $303,129,000 in 1998, $244,640,000 in 1997
and $197,391,000 in 1996, which amounted to 42%, 44% and 49%, respectively, of
software product and maintenance revenues for these years.
 
   Sales and Marketing. Sales and marketing expenses increased to $318,453,000
in 1998, from $263,986,000 in 1997 and $218,435,000 in 1996. The increase in
sales and marketing expenses during 1998 was primarily attributable to costs
associated with the significant expansion of the domestic and international
outside sales forces, as well as higher commission and bonus expenses related
to the increase in software products revenues. Sales and marketing expenses
represented 33%, 36% and 39% of total revenues in 1998, 1997 and 1996,
respectively. The decrease in sales and marketing expenses as a percentage of
total revenues during 1998, as compared to 1997, was primarily attributable to
continuing benefits derived from the Company's 1997 restructuring plan, as well
as revenue growth exceeding certain sales and marketing fixed costs. During the
second quarter of 1997, the Company realigned its inside sales force to be more
compatible with its strategy of providing complete IT infrastructure solutions
and to correspond with the restructuring plan. This realignment resulted in a
significant reduction in the inside sales force. The Company also consolidated
certain remote sales facilities. Consequently, sales and marketing expenses as
a percentage of total revenues decreased during 1997.
 
   General and Administrative. General and administrative expenses increased to
$60,941,000 in 1998, from $50,158,000 in 1997 and $42,230,000 in 1996. The
increase during 1998 was primarily attributable to higher employee-related
expenses resulting from recent acquisitions and increases in legal expenses
related to certain on-going legal proceedings. The increase in general and
administrative expenses in 1997, as compared to 1996, was primarily due to the
costs associated with integrating recently acquired businesses and maintaining
the infrastructure to support the restructured company, including
administrative system upgrade expenses and associated consulting fees, as well
as the amortization of intangible assets relating to the Company's
 
                                       18
<PAGE>
 
convertible debt offerings. General and administrative expenses represented 6%,
7% and 8% of total revenues in 1998, 1997 and 1996, respectively. As a
percentage of total revenues, general and administrative expenses
have decreased during 1998 and 1997 due to the Company's continual cost
containment efforts, as well as integration of acquisitions.
 
   Special General and Administrative Charges. Special general and
administrative charges were $10,982,000 for 1998, $13,513,000 for 1997, and
$1,978,000 for 1996. During 1998, the company re-evaluated the fair value of
certain assets acquired from prior acquisitions in conjunction with the
integration procedures initiated in the second quarter of 1997. Specific assets
which were deemed to have no future value were written off in 1998. The 1998
charges also included certain non-recurring legal expenses. In the second
quarter of 1997, the Company performed integration procedures related to past
acquisition activity in conjunction with, but not specifically as part of, the
restructuring plan executed during that period. Accordingly, the Company
evaluated the fair value of assets recorded through prior acquisitions and
identified certain trade receivables, prepaid expenses and intangible assets
which had no future value. The respective balances of these assets were written
off during the second quarter of 1997. The Company also expensed severance and
other employee benefits for certain employees of acquired companies who were
terminated as a result of the integration efforts. The Company recorded total
charges of $13,513,000 in the quarter ended June 30, 1997 in connection with
the integration procedures discussed above. During 1996, the Company's wholly-
owned subsidiary, Logic Works (acquired as of May 28, 1998) changed the
depreciable lives of its computer equipment and wrote-down certain other
assets, which resulted in a special general and administrative charge of
$1,978,000.
 
   Restructuring Charges. In August 1996, the Company's wholly-owned
subsidiary, LBMS (acquired as of May 12, 1998), executed a plan to restructure
its operations. During the second half of 1996, LBMS recorded a restructuring
charge of $14,109,000, net of $3,512,000 in sublease rentals and recoveries
from the sale of a product line. The restructuring charge consisted primarily
of abandoned lease costs, severance and other personnel costs and write-offs of
excess equipment and other assets. During 1997, LBMS recorded a restructuring
benefit of $1,490,000 related to sublease rental activity. This benefit was
offset against the Company's restructuring charge recorded in 1997.
 
   In the fourth quarter of 1996, the Company's wholly-owned subsidiary, Logic
Works (acquired as of May 28, 1998), implemented a restructuring plan to
streamline its operations by reducing its workforce, consolidating and
reorganizing certain operations and writing off certain fixed assets and other
impaired assets. The plan included the closing and moving of several offices
and the termination of approximately 25 employees across all departments. Logic
Works recorded a charge of $2,203,000 relating to this restructuring. The
Company had $10,963,000 of accrued restructuring costs at December 31, 1996.
 
   During the second quarter of 1997, the Company executed a restructuring plan
to consolidate its sales, marketing, business development and product
development operations to achieve cost efficiencies through the elimination of
redundant functions. These redundancies resulted primarily from businesses
acquired over the previous three years. The Company also realigned its business
units and inside sales force to redirect focus on its strongest product lines
and better integrate the efforts of certain product development teams. As part
of the plan, the Company reduced its worldwide work force by approximately 10%,
eliminating approximately 400 positions, primarily in the areas of product
development and support, marketing and inside sales and, to a lesser extent,
professional services and administration.
 
   The Company recorded a one-time charge of $57,319,000 during the second
quarter of 1997 related to the restructuring plan. This charge was offset by a
restructuring benefit of $1,490,000 recorded by LBMS resulting in a net
consolidated charge of $55,829,000. The restructuring charge included the
following expenses: $24,032,000 for facility-related costs, including a reserve
for estimated lease obligations associated with the closing of office
facilities; $3,510,000 for write-offs of excess equipment, furniture and
fixtures; $19,413,000 for write-offs of capitalized software costs and other
intangible assets related to the termination of development efforts for certain
discontinued products, as well as penalties for the cancellation of
distributorship agreements
 
                                       19
<PAGE>
 
for such products; and $10,364,000 for severance and other employee-related
costs of the terminated staff. Of the $57,319,000 restructuring charge, the
Company paid out approximately $17,784,000 and wrote off $19,687,000 of non-
cash charges during 1997. The Company had $29,321,000 of accrued restructuring
costs at December 31, 1997.
 
   During 1998, the Company recognized a restructuring benefit of $10,964,000
related to the Company's occupation of previously vacated facilities and the
relief of obligations under cancelled lease agreements, as well as sublease
rental activity. This restructuring benefit represents the recovery of certain
restructuring
charges recorded by the Company in the second quarter of 1997, as discussed
above. The Company also paid approximately $10,682,000 during 1998 related to
previously accrued restructuring costs. The Company had $7,675,000 of accrued
restructuring costs at December 31, 1998. The Company anticipates that
approximately $2,390,000 of these costs will be paid during 1999, $1,576,000
during 2000, $1,550,000 during 2001, $1,419,000 during 2002 and $740,000 after
2002. For a discussion of the Company's 1999 restructuring, see "--Recent
Developments."
 
   Merger Costs. Merger costs were $40,065,000, $8,927,000 and $5,782,000 in
1998, 1997 and 1996, respectively. Merger costs relate to acquisitions
accounted for as poolings of interests and include investment banking and other
professional fees, employee severance payments, costs of closing excess office
facilities and various other expenses. The significant increase in merger costs
in 1998 related primarily to the Company's acquisitions of Mastering, LBMS and
Logic Works. The Company may incur merger costs in connection with future
acquisitions accounted for as poolings of interests, which would reduce
operating and net income in the periods in which the acquisitions are
consummated. For a discussion of the Company's acquisition of Memco Software,
Ltd. ("Memco"), see "--Recent Developments." See also "--Recent Developments"
for information regarding the Company's announcement on January 27, 1999 that
the Company was suspending any new acquisition activity, for at least the next
six months, to focus solely on strengthening the Company's core operations.
 
   Acquired In-Process Technology. Acquired in-process technology charges were
$37,918,000, $67,904,000 and $49,451,000 in 1998, 1997 and 1996, respectively.
Acquired in-process technology charges relate to acquisitions of software
companies and product technologies accounted for under the purchase method, in
which portions of the purchase prices were allocated to acquired in-process
technology and expensed immediately because the technologies acquired had not
reached technological feasibility based on the status of design and development
activities.
 
   In June 1998, the Company acquired network monitoring technology from Geneva
Software, Inc. ("Geneva Software"). A portion of the purchase price was
attributed 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 a network monitoring
device. The in-process technology involved new major monitoring capabilities
for hubs, routers and switches, along with several performance capabilities.
 
   The Company carefully assessed the fair value of the acquired in-process
technology using an income approach. Future cash flows were projected over five
years and discounted to present value using a discount rate of approximately
20%. The Company believes the discount rate is appropriate given the level of
risk of unsuccessful completion of the technology, considering it was estimated
to be approximately 70% complete as of the acquisition date. The Company
anticipates incurring approximately $1,000,000 of additional research and
development costs, with an anticipated completion date of June 1999. In
projecting the future revenue streams from the project, the Company considered
many factors including competition, network management growth estimates, time
to market, and additional sales and marketing leverage, as well as the impact
of larger transactions upon global enterprises to which Geneva Software was not
accustomed.
 
   In June 1998, the Company acquired mainframe asset management and cost
modeling capabilities from Systems Management Solutions, Inc. ("SMS"). A
portion of the purchase price was attributed to acquired in-process technology,
as the development work associated with the project had not reached
technological
 
                                       20

feasibility and was believed to have no alternative future use other than for
asset management and cost modeling. The in-process technology involved
implementing the mainframe technology design onto additional mid-range
platforms such as UNIX and NT.
 
   The Company carefully assessed the fair value of the acquired in-process
technology using an income approach. Future cash flows were projected over five
years and discounted to present value using a discount rate of 20%. The Company
believes the discount rate is appropriate given the level of risk of
unsuccessful completion of the technology considering it was estimated to be
over two-thirds complete as of the acquisition date. The Company has brought
this technology to feasibility, incurring approximately $400,000 of additional
research and development costs. In projecting the future revenue streams from
the project, the Company considered many factors including competition, asset
management growth estimates, time to market and additional sales and marketing
leverage, as well as impact of larger transactions upon global enterprises to
which SMS was not accustomed.
 
   In June 1998, the Company acquired modeling technologies from ICON
Computing, Inc. ("ICON"). A portion of the purchase price was attributed to
acquired in-process technology, as development work associated with the
projects had not reached technological feasibility and was believed to have no
alternative future use other than as modeling tools.
 
   The Company 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%. The Company
believes the discount rate is appropriate given the level of risk of
unsuccessful completion of the technologies as they were estimated to be over
50% complete as of the acquisition date. The Company anticipates incurring
approximately $1,200,000 of additional research and development costs, with an
anticipated completion date of December 1999. In projecting the future revenue
streams from the projects, the Company considered many factors including
competition, market growth estimates, time to market and additional sales and
marketing leverage, as well as the impact of larger transactions upon global
enterprises to which ICON was not accustomed.
 
   In October 1998, the Company acquired enterprise-wide directory service and
software solutions from OpenDirectory Pty Limited and OpenDirectory, Inc.
(collectively, "OpenDirectory"). A portion of the purchase price was attributed
to acquired in-process technology, as the development work associated with the
projects had not reached technological feasibility and was believed to have no
alternative future use other than as directory service tools. The in-process
technology involved new major functionality, security, performance and
management capabilities to the directory technology. Furthermore, the in-
process technology involved critical operational features required by the
market, including strong encryption capabilities, certificate administration, a
database port using open database connectivity, major throughput enhancements,
load sharing, Year 2000 compliance, internationalization and integration with
other technologies of the Company.
 
   The Company carefully assessed the fair value of the acquired in-process
technology using an income approach. Future cash flows of the projects were
projected over five to seven years discounted to present value using a discount
rate of 25%. The Company believes the discount rate is appropriate given the
level of risk of unsuccessful completion of the technologies as they were
estimated to be approximately 50% complete as of the acquisition date. The
Company anticipates incurring approximately $2,500,000 of additional research
and development costs with an anticipated completion date of April 2000. In
projecting the future revenue streams from the projects, the Company considered
many factors including competition, market growth estimates, time to market and
additional sales and marketing leverage, as well as the impact of larger
transactions upon global enterprises to which OpenDirectory was not accustomed.
 
   During 1998, the Company also acquired eight other software businesses and
product technologies. Portions of the purchase prices were attributed to
acquired in-process technology, as the development work associated with the
projects had not reached technological feasibility and were believed to have no
alternative future use. The Company anticipates incurring approximately
$6,000,000 of additional research and
 
                                       21

development costs over a short time frame and expects these projects to be
completed within the next 12 to 18 months.
 
   The following summary presents information concerning the purchase price
allocations for the acquisitions accounted for under the purchase method during
1998.

(1) Purchase prices include costs associated with the acquisition.
(2) During the fourth quarter of 1998, the Company changed its estimate of
    allocating purchase price and reduced its acquired in-process technology
    expense by $4,827,000 and increased goodwill by the same amount.

   The forecasts used in valuing acquired in-process technologies were based
upon assumptions the Company believed to be reasonable but which were
inherently uncertain and unpredictable. For this reason, actual results may
vary from projected results. The Company did not assume in its valuation model
any material change in its profit margins or any material increases in selling,
general and administrative expenses as a result of the acquisitions.
 
   Without successful completion of the remaining research and development
efforts on the acquired in-process technologies, including integration with the
Company's existing products, the end result would be to fail to fulfill the
products' design specifications and, in turn, fail to meet market requirements.
As a result, the Company would not realize the future revenues and profits
attributed to the acquired in-process research and development. Ultimately, the
Company would fail to realize the expected return on such investments. The
Company has not planned any significant expense reductions or synergies as a
result of the acquisitions and thus does not believe that the failure to
achieve the projected results from the acquired in-process technologies would
have a material impact on the Company as a whole.
 
   The Company believes that it will complete the projects in a timely manner
and within original cost estimates. Significant efforts are necessary to
develop the acquired in-process technology into commercially viable products,
principally related to the completion of all designing, prototyping, coding,
scalability verification and testing activities that are required to establish
that the proposed technologies would meet their design specifications. The
acquired in-process technology projects are expected to begin to result in
material cash flows in 12 to 24 months subsequent to their completion, assuming
their successful completion.
 
   The Company has reviewed its projections of revenues and estimated costs of
completion for acquisitions involving acquired in-process technology
consummated from 1993 through 1997. The Company has compared these projections
with actual revenues and costs and determined that, in the aggregate, the
average margin of error between the estimated and actual results was 5-10%.
 
   The Company may continue to incur charges for acquired in-process technology
in connection with future acquisitions, which would reduce operating and net
income for the periods in which the acquisitions are consummated. See "--Recent
Developments" below.
 
                                       22

 Operating Loss
 
   For the reasons discussed above, the Company generated operating income of
$20,317,000 in 1998, as compared to an operating loss of $102,141,000 in 1997
and an operating loss of $101,609,000 in 1996. The Company had operating
margins of 2%, (14)% and (18)% in 1998, 1997 and 1996, respectively. The
Special Charges incurred in 1997 and 1996 contributed significantly to the
operating losses and negative operating margins experienced by the Company.
Excluding the Special Charges, the Company would have reported operating income
of $98,318,000 in 1998, operating income of $44,032,000 in 1997 and an
operating loss of $28,086,000 in 1996. Excluding such charges, the Company
would have reported operating margins of 10%, 6% and (5)% in 1998, 1997 and
1996, respectively. During 1998 and 1997, the Company improved its operating
margin, excluding Special Charges, through its cost containment efforts and the
savings realized from the restructuring plan. The Company may continue to incur
acquisition-related charges, as well as expenses related to the integration of
acquired businesses, which could materially adversely affect operating results
in the periods in which such acquisitions are consummated and in subsequent
periods.
 
 Other Income
 
   Other income was $10,253,000 in 1998 as compared to $20,497,000 in 1997 and
$8,075,000 in 1996. The decrease in other income in 1998, as compared to 1997,
was primarily attributable to the interest expense on the Company's convertible
subordinated notes issued in December 1997 and lower unrealized holding gains
on
certain trading securities, the market values of which decreased during 1998.
The decrease in other income during 1998, as compared to 1997, was partially
offset by greater interest income related to higher cash and investment
balances during 1998 and greater realized gains on sales of investment
securities. The increase in other income during 1997, as compared to 1996, was
primarily attributable to unrealized holding gains that resulted from the
reclassification of certain available-for-sale securities into the trading
classification; unrealized holding gains on trading securities, the market
values of which increased during 1997; and realized gains on sales of
investment securities. The increase in other income during 1997, as compared to
1996, was partially offset by interest expense on the Company's convertible
subordinated notes issued in November 1996 and December 1997. Because
unrealized holding gains and losses for trading securities are reflected in
pre-tax earnings, fluctuations in the market value of these securities are
continuously recorded as additions to, or deductions from, other income until
the securities are sold. See "--Liquidity and Capital Resources."
 
 Income Taxes
 
   The Company recognized income tax expense of $33,038,000 in 1998, an income
tax expense of $23,459,000 in 1997 and an income tax benefit of $9,752,000 in
1996. The income tax expense recorded in 1997 included an additional expense of
$5,070,000 recorded in the second quarter of 1997, to reduce the Company's
deferred tax asset to a level that more likely than not will be realized in
future periods.
 
   The Company has available approximately $333,270,000 of net operating loss
carryforwards and $10,574,000 of tax credit carryforwards, which are available
to reduce future Federal income taxes, if any. The net operating loss
carryforwards expire between 2004 and 2018. The tax credit carryforwards expire
between 2002 and 2018. Some of the Company's tax carryforwards are subject to
limitations as to the amounts that may be used in any particular future year.
 
 Net Loss
 
   For the reasons discussed above, the Company incurred a net loss of
$2,468,000 in 1998, as compared to $106,128,000 in 1997 and $87,194,000 in
1996. The Special Charges incurred in these years contributed significantly to
the net losses experienced by the Company.

Recent Developments
 
   Effective January 1, 1999, the Company reorganized its legal structure into
a holding company structure, under which the operations of the Company are
conducted through direct and indirect wholly-owned subsidiaries. Certain of
these subsidiaries, including PLATINUM technology IP, inc. and PLATINUM
technology, inc. (collectively, the "Obligor Subsidiaries") commenced
substantive operations. The corporate structural changes were made to reflect
the Company's global focus and to provide greater operational flexibility, as
well as allow for more efficient tax planning in the future. The Obligor
Subsidiaries were established with de minimis capitalizations from the Company
as of December 31, 1998. The Obligor Subsidiaries are joint and several
obligors on the 1996 Notes (as defined below) and the 1997 Notes (as defined
below) previously issued by the Company. There are currently no significant
restrictions on the Company's ability to obtain funds from the Obligor
Subsidiaries.
 
   On January 27, 1999, the Company announced a suspension of any new
acquisition activity, for at least the next six months, to focus solely on
strengthening its core operations.
 
   On February 22, 1999, the Company announced a restructuring plan to
streamline operations, increase profitability, and deliver greater value to
customers and shareholders. The Company believes that this restructuring plan
will yield approximately $90 million in annual savings and significantly
increase operating margins. As a result of these actions, the Company expects
to incur a one-time charge of approximately $90 to $110 million in the first
quarter of 1999.
 
   On February 23, 1999, the Company and a major financial services company
announced the formation of a new finance entity, PLATINUM technology Global
Finance ("Global Finance"). Global Finance was established to provide the
Company's enterprise software customers with customized financing solutions
designated to better control and reduce their overall information technology
costs. The Company anticipates that Global Finance will be operational
beginning in the second quarter of 1999.
 
   On March 29, 1999, the Company acquired all of the outstanding ordinary
shares of Memco Software, Ltd. ("Memco"), a leading provider of information
security software, in exchange for 13,751,923 shares of the Company's Common
Stock. The Company also assumed Memco stock options which converted into
options to purchase 3,279,498 shares of the Company's Common Stock. This
transaction is expected to be accounted for as a pooling of interests. Costs
incurred in connection with this transaction will be expensed in the first
quarter of 1999.
 
   On March 29, 1999, the Company and Computer Associates International, Inc.
("CA") announced the execution of a merger agreement pursuant to which CA has
agreed to acquire the Company through a cash tender offer. Under the terms of
the merger agreement, a wholly-owned subsidiary of CA will offer to purchase
all outstanding shares of the Company's Common Stock for $29.25 per share.
Consummation of the tender offer is subject to certain conditions, including
the condition that at least a majority of the outstanding shares of the
Company's Common Stock be tendered and not withdrawn. Consummation of the
tender offer is also subject to the expiration or termination of any applicable
antitrust waiting period. Following completion of the tender offer and subject
to certain conditions, the Company will merge into the subsidiary of CA, with
the Company surviving as a wholly-owned subsidiary of CA. The transactions are
currently expected to be completed in mid-1999.
 
Liquidity and Capital Resources
 
   The Company's cash, cash equivalents and investments were $302,072,000 and
$358,204,000 at December 31, 1998 and 1997, respectively.
 
   For the year ended December 31, 1998, cash and cash equivalents decreased
$43,099,000, from $233,024,000 at December 31, 1997 to $189,925,000 at December
31, 1998. This decrease was primarily attributable to payments for purchased
and developed software of $90,894,000 and for acquisitions of $55,132,000,
offset by cash provided by operating activities of $96,137,000 and proceeds
from the exercise of stock options and from the Company's employee stock
purchase plan of $59,588,000.
 
                                       24
<PAGE>
 
   For the year ended December 31, 1997, cash and cash equivalents increased
$54,363,000, from $178,661,000 at the beginning of the year to $233,024,000 at
the end of the year. This increase was attributable primarily to net proceeds
of $144,967,000 from the issuance of convertible notes and net cash provided by
operating activities of $49,242,000, offset by cash used in investing
activities of $156,292,000.
 
   For the year ended December 31, 1996, cash and cash equivalents increased
from $148,992,000 at the beginning of the year to $178,661,000 at the end of
the year, with the primary sources of cash being the net proceeds from the
issuance of convertible notes of $110,783,000 and from the issuance of common
stock of $49,973,000, offset principally by cash used in investing activities
of $115,238,000.
 
   In recent years, the Company's sources of liquidity have primarily been
funds from capital markets and sales of installment receivables. The Company
believes the funding available to it from these sources, as well as cash flows
from operations, will be sufficient to satisfy its working capital and debt
service requirements for the foreseeable future. The Company's capital
requirements are primarily dependent on management's business plans regarding
the levels and timing of investments in existing and newly acquired businesses
and technologies. These plans and the related capital requirements may change
based upon various factors, such as the Company's strategic opportunities,
developments in the Company's markets, the timing of closing and integrating
acquisitions and the conditions of financial markets.
 
   The Company had trade and installment accounts receivable, net of
allowances, of $417,955,000 and $279,919,000 as of December 31, 1998 and 1997,
respectively. The Company sells software products and services to customers in
diversified industries and geographic regions and, therefore, has no
significant concentration of credit risk. Historically, a substantial amount of
the Company's revenues have been recorded in the third month of any given
quarter, with a concentration of such revenues in the last week of the third
month. This trend results in a high balance of accounts receivable relative to
reported revenues at the end of any quarterly reporting period.
 
   The Company sells a significant portion of its installment receivables to
third parties. Installment receivables represent amounts collectible on long-
term financing arrangements and include fees for product licenses, upgrades and
maintenance, sometimes also bundled with professional services contracts.
Installment receivables are generally financed over five years, with interest
payable on the license and upgrade portions only. Over the past three years,
the Company executed an increasingly greater number and higher dollar value of
sales transactions having long-term financing arrangements, primarily
attributable to sales of product bundles and integrated product suites.
Consequently, the Company's volume of installment receivable sales increased
significantly over the past two years. The Company anticipates that the
operations of Global Finance will result in the direct financing of the
Company's customers by Global Finance, as compared with the Company's current
practice of recording and subsequently selling certain installment receivable
balances.
 
   The Company receives proceeds equal to the entire installment receivable
balance sold to a third party finance company, net of an amount representing
the interest to be earned by the finance company. The finance company collects
customer remittances over the term of the agreement. Proceeds from the sale of
receivables were approximately $319,782,000, $206,916,000 and $129,328,000 for
the years ended December 31, 1998, 1997 and 1996, respectively. Accounts
receivable sold with recourse were $19,373,000 for the year ended December 31,
1996. There were no accounts receivable sold with recourse for the years ended
December 31, 1998 and 1997, and as of December 31, 1998, there were no
remaining potential recourse obligations for accounts receivable sold with
recourse. The Company has an agreement with a third party that provides for
potential recourse obligations in the form of a loss pool based on the
performance of the related accounts receivable portfolio. Under the terms of
that agreement, potential recourse obligations at December 31, 1998 were
approximately $20,000,000. Based on the credit ratings of the underlying
obligors to the accounts receivable and the performance history of the accounts
receivable portfolio, the Company has assessed the exposure related to these
recourse obligations and does not expect the potential liability to have a
material adverse effect on the Company's future results of operations.
 
 
                                       25
<PAGE>
 
   The Company's installment receivables are recorded net of unamortized
discounts and deferred maintenance fees. When these receivables are sold, the
Company reduces the gross installment receivable balance. Additionally, the
Company reclassifies the deferred maintenance, which was previously reflected
as a reduction of the related installment receivable balance, to a liability.
The deferred maintenance is recognized into income ratably over the term of the
maintenance agreement.
 
   The Company had long-term acquisition-related payables of $6,388,000 and
$18,320,000 and other long-term obligations of $266,422,000 and $267,239,000 as
of December 31, 1998 and 1997, respectively. The convertible subordinated notes
issued by the Company in November 1996 and December 1997 constituted the
majority of the balances in long-term obligations at December 31, 1998 and
1997. The Company completed an offering of convertible subordinated notes due
December 15, 2002 in December 1997 (the "1997 Notes"). The 1997 Notes bear
interest at 6.25% annually, and the holders of the 1997 Notes have the option
to convert them into shares of Common Stock, at any time prior to maturity, at
a conversion price of $36.05 per share. The 1997 Notes are redeemable at the
option of the Company, in whole or in part, at any time during the 12-month
period commencing December 15, 2000 at 102.5% of their principal amount and
during the 12-month period commencing December 15, 2001 at 101.25% of their
principal amount. The Company received proceeds, net of issuance costs, of
$144,967,000 from the offering of the 1997 Notes. The Company completed an
offering of convertible subordinated notes due November 15, 2001 in November
1996 (the "1996 Notes"). The 1996 Notes bear interest at 6.75% annually, and
the holders of the 1996 Notes have the option to convert them into shares of
Common Stock, at any time prior to maturity, at a conversion price of $13.95
per share. The 1996 Notes are redeemable at the option of the Company, in whole
or in part, at any time during the 12-month period commencing November 15, 1999
at 102.7% of their principal amount and during the 12-month period commencing
November 15, 2000 at 101.35% of their principal amount. The Company received
proceeds, net of issuance costs, of $110,783,000 from the offering of the 1996
Notes. The Company currently has total debt service obligations of
approximately $35,000,000 for 1999, consisting primarily of obligations to pay
interest on the 1996 Notes and the 1997 Notes, as well as acquisition-related
payables. Based on current outstanding indebtedness, the Company estimates its
debt service requirements to be approximately $15,000,000, $129,000,000 and
$156,000,000 for 2000, 2001 and 2002, respectively, which amounts include the
outstanding principal balance of the 1996 Notes in 2001 and the outstanding
principal balance of the 1997 Notes in 2002.
 
   The Company currently has an unsecured bank line of credit for an aggregate
of $65,000,000 with American National Bank and Trust Company of Chicago, under
which borrowings bear interest at rates ranging from approximately LIBOR plus
1.25% to the bank's prime rate. As of March 23, 1999, the Company had no
outstanding borrowings under this line of credit, but had aggregate letters of
credit outstanding for approximately $12,846,000, with expiration dates ranging
from May 1999 to April 2000. These letters of credit reduce the balance
available under its lines of credit. Under the credit agreement, the Company
has agreed: (i) to maintain a ratio of current assets to current liabilities of
at least 1.0 to 1.0; (ii) to maintain a tangible net worth of not less than
$275,000,000; and (iii) to maintain a ratio of total liabilities to tangible
net worth of not more than 1.0 to 1.0. Additionally, the Company has a line of
credit with Fuji Bank for approximately $2,134,000 (based upon current exchange
rates), under which borrowings bear interest at a rate of 2.125%. As of March
23, 1999, the Company had outstanding borrowings of approximately $1,067,000
under this line of credit.
 
Foreign Currency Exchange Rates
 
   Historically, the Company has derived a significant portion of its revenues
from international sales. The Company's total level of foreign sales and the
profitability of these sales could be materially adversely affected by exchange
rate fluctuations. To date, fluctuations in foreign currency exchange rates
have not had a material effect on the Company's results of operations or
liquidity. However, the Company closely monitors its foreign operations and net
asset position to ascertain the need for hedging foreign currency exchange
risk. Since 1997, the only exposure related to foreign currency exchange for
which the Company has considered hedging appropriate has been related to short-
term intercompany balances. These non-functional currency balances are hedged
by purchases and sales of forward exchange contracts to reduce this exchange
rate exposure. At December 31, 1998, the Company held an aggregate of
approximately $32,692,000 in notional amount of
 
                                       26
<PAGE>
 
forward exchange contracts. As the Company's operations expand in international
regions outside Western Europe, where the Company's international operations
are currently concentrated, the Company may increasingly need to hedge foreign
currency exchange risk. See also "Item 7A. Quantitative and Qualitative
Disclosures About Market Risk."
 
Year 2000 Considerations
 
 Demand for the Company's Products and Services
 
   The Company sells certain software products, and provides related consulting
services, which assist customers in solving their own Year 2000 problems. For
obvious reasons, the demand for these products has been created by the
impending arrival of the Year 2000. Demand for certain of the Company's other
products may also be generated by customers who are replacing or upgrading
software to accommodate the Year 2000 date change. As a result, demand for some
of the Company's products and services may diminish as the Year 2000 arrives,
which could negatively impact the Company's revenue growth rate. Additionally,
because the Company believes that some of its customers are allocating a
substantial portion of their 1999 IT budgets to Year 2000 compliance, sales of
certain of the Company's traditional product offerings may be adversely
affected through the end of 1999.
 
 Compliance of the Company's Products
 
   The Company believes that substantially all of the products that it
currently sells or maintains are now Year 2000 compliant. These products have
met rigorous compliance criteria and have undergone extensive testing to detect
any Year 2000 failures. In general, these Year 2000 compliance efforts have
been part of the Company's ongoing software development process, and the
Company estimates that the associated incremental costs have totaled less than
$10,000,000. Despite these efforts, certain of the Company's products may
contain undetected Year 2000 problems, and customers of the Company who have
discontinued maintenance may be running old product versions that are not
compliant.
 
   The Company licenses a small percentage of the products that it sells from
third parties. Although these products have generally been warranted to the
Company as Year 2000 compliant, they have generally not been subject to the
same extensive Company testing as those products developed or acquired by the
Company. The Company has therefore been engaged in and is nearing the end of an
aggressive effort, working with its third party product suppliers, and
conducting its own tests, to obtain a very high level of assurance of Year 2000
compliance.
 
   Under certain circumstances, the Company may decide to acquire software
products that are not currently Year 2000 compliant. There can be no assurance
that the Company will be successful in bringing such products into compliance
prior to January 1, 2000, particularly any products acquired in late 1999. The
Company is developing contingency plans to inform customers if any Year 2000
problems remain.
 
   Because the Company's products are typically used in high volume information
systems that are critical to its customers' operations, business interruptions,
loss or corruption of data or other major problems resulting from a failure of
a product to process data correctly could have significant adverse consequences
to its customers. Although the Company believes that its software license
agreements provide it with substantial protection against liability, the
Company cannot predict whether or to what extent any legal claims will be
brought against the Company, or whether the Company will otherwise be adversely
affected, as a result of any such adverse consequence to its customers.
Similarly, the Company may face legal claims or suffer other adverse
consequences as a result of any information system failures of companies for
which the Company has provided consulting services.
 
 Internal Systems and Technical Infrastructure
 
   The Company has implemented a comprehensive program, with a dedicated
project manager, to address Year 2000 issues in the Company's internal systems,
including IT and non-IT systems, and technical
 
                                       27
<PAGE>
 
infrastructure. As part of this program, the Company is analyzing Year 2000
compliance with respect to the services, building systems and equipment at the
properties at which the Company operates. It is also verifying that other third
parties upon which the Company relies, including payroll and employee benefit-
related service providers and financial institutions, are or will be compliant.
 
   The Company believes that its Year 2000 internal systems and technical
infrastructure compliance program is approximately 85% complete and that the
remainder will be completed well in advance of January 1, 2000. This program
includes eight phases: (1) inventorying of all of the Company's software and
hardware (completed); (2) identifying and testing all internal mission critical
business applications and correcting any Year 2000 problems in these
applications (expected to be completed by the end of March 1999); (3)
identifying the interfaces from the mission critical business applications to
third party systems and confirming the compliance of these third party systems
(all of these systems are expected to be compliant by the first quarter of
1999); (4) identifying critical vendors in purchasing and travel (vendor
questionnaire responses are now being reviewed); (5) informing the Company's
internal user community about this Year 2000 program (an intranet site has been
established and is regularly updated); (6) educating the Company's internal
user community about Year 2000 issues and monitoring user compliance (in
progress since fourth quarter of 1998); (7) identifying noncritical vendors and
confirming their Year 2000 compliance (planned for the second quarter of 1999);
(8) preparing contingency plans for mission critical business applications,
technical infrastructure and critical vendors (in progress and expected to be
completed by September 1999).
 
   The Company expects that it will not incur any significant incremental costs
for replacement or upgrading of systems that are not Year 2000 compliant, and
it estimates that total personnel expenses relating to the Company's
remediation program will be approximately $1,900,000. Therefore, the Company
does not believe that the costs associated with the program will have a
material effect on the Company's financial condition or results of operations.
 
   The Company believes that, although its risk of operational disruption from
systems failures due to Year 2000 problems is minimal, the Company could suffer
adverse consequences as a result of interruptions in electrical power,
telecommunications or other critical third party infrastructure services. In a
worst case scenario, Company computer systems could be rendered inoperable, and
the Company could be unable to develop or support its products. The Company is
currently developing a specific contingency plan to deal with these issues.
This plan, which is expected to be completed by May 1999, is expected to
provide for relocation of employees and reliance on Company owned electrical
generators and cellular telephones.
 
Other Risks And Uncertainties That Could Affect Future Operating Results
 
   In addition to the risks discussed above under "--Foreign Currency Exchange
Rates" and "--Year 2000 Considerations," below under "--Quarterly Comparisons"
and elsewhere in this Annual Report on Form 10-K, the following risks,
uncertainties and other factors could affect the Company's future business,
financial condition and results of operations.
 
 Rapid Technological Change; Reliance on New Products and Markets
 
   The Company expects the market for its products to continue to be subject to
frequent and rapid changes in technology and customer preferences. The
emergence of new product technologies and industry standards could cause the
Company's existing products to become obsolete and unmarketable. The Company's
growth and future financial performance will depend upon its ability to develop
and introduce new products and enhance existing products to accommodate the
latest technological advances and customer requirements. If the Company fails
to anticipate or adequately respond in a timely fashion to changes in
technology and customer preferences, its business, financial condition or
results of operations could be materially adversely affected. Additionally, the
Company's future growth and financial performance will be adversely affected if
(1) new products developed by the Company are not accepted in the marketplace;
(2) other software vendors develop and market products which are superior to
the Company's products and gain greater acceptance in the marketplace; or (3)
customers delay purchases in anticipation of technological changes.
 
 
                                       28
<PAGE>
 
 Dependence on Mainframe Products
 
   The Company derives a significant percentage of its revenues from products
for mainframe computers and believes that mainframes will continue to be an
integral part of organizations' open systems IT environments. However, there
has been debate in the marketplace regarding the future role of mainframe
computers. Although the Company now derives a majority of its revenues from
non-mainframe products and services, if there were a decline in utilization of
mainframe computers, the Company's business, financial condition and results of
operations could be materially adversely affected.
 
 Risks of Reliance on an Acquisition Strategy
 
   The Company has grown largely through the acquisition of businesses and
technologies. Since mid-1994, the Company has acquired 48 businesses and 31
technologies. The Company believes that its future growth depends, in part,
upon the continued success of this acquisition strategy. In the future, the
Company may not be able to successfully identify, acquire on favorable terms or
integrate suitable businesses or technologies. The Company may also face
increased competition for acquisition opportunities, which may adversely affect
its ability to complete suitable acquisitions and may increase the costs of
completing acquisitions. An acquisition strategy involves a number of other
risks and challenges, including the following: (1) diversion of management's
attention; (2) integration of the operations and personnel of acquired
companies; (3) incorporation of acquired products into existing product lines;
(4) adverse short-term effects on reported operating results; (5) amortization
of acquired intangible assets; (6) assumption of liabilities of acquired
companies; (7) potential dilutive effect on the Company's stockholders from
continued issuance of common stock as consideration for acquisitions; (8)
adverse effect of acquisition-related charges, costs and expenses on operating
and net income; (9) potential loss of key employees; and (10) difficulty of
presenting a unified corporate image.
 
 Highly Competitive Markets
 
   The Company operates in the highly competitive markets of information
technology infrastructure products and professional services, and the Company
expects competition to increase. Many of the Company's current and prospective
competitors have significantly greater financial, technical and marketing
resources than the Company. In addition, many prospective customers have the
internal capability to implement solutions to their information technology
infrastructure problems.
 
 Risk of Damage Claims and Costs Resulting from Product Defects
 
   Upon release, the Company's software products typically contain certain
errors or bugs which are usually resolved through the regular maintenance and
updating process. However, products may contain more serious errors, failures
or bugs which may not be discovered until the Company has delivered the
products to customers. As a result of serious failures or bugs, (1) the
Company's customers could suffer major business interruptions or other problems
which could lead to claims for damages against the Company; (2) customers may
delay their purchases of products until they are satisfied that the problems
have been resolved; (3) customers may decide not to purchase the defective
products or other Company products; (4) customers who have already received the
defective products may return them for refunds and possibly may bring other
claims against the Company; (5) the Company may need to devote significant
financial and product development resources to fix software defects; and (6)
the Company may be forced to delay the introduction of new products or new
versions of existing products. The Company believes that its software license
agreements provide it with substantial protection against liability. In
addition, the Company possesses "errors and omissions" insurance covering the
Company in the event it is held responsible for losses suffered by its
customers due to product defects. Nevertheless, the Company may be found liable
for customer losses, and its insurance may not be adequate to cover such
losses. If the Company's products contain serious failures or bugs, the
Company's business, results of operations or financial condition may be
materially adversely affected.

 Dependence on Proprietary Technology
 
   The Company's success is heavily dependent upon its proprietary software
technology. The Company establishes and protects its proprietary rights through
a combination of contractual rights, trademarks, trade secrets, patents and
copyright laws. However, the steps the Company has taken to protect its
proprietary rights may not be adequate to prevent the unauthorized use or
imitation of its products. Additionally, the Company has derived a significant
percentage of its revenues from sales in foreign countries. Certain of these
countries may afford less protection to proprietary technology rights than is
provided under United States laws. The Company does not believe that its
products or technologies materially infringe on the intellectual property
rights of others. However, infringement claims may be asserted against the
Company in the future. Any claim or litigation, with or without merit, or an
adverse determination in such claims or litigation, could be costly and could
have a material adverse effect on its results of operations and financial
condition.
 
   Dependence on DB2
 
   The Company expects to continue to derive a significant portion of its
revenues from licensing products that enhance the performance of IBM's DB2
software for managing mainframe corporate databases. If IBM decreases its
commitment to DB2 or there is a decline in the market's acceptance and
utilization of DB2, the Company's business could be materially adversely
effected. Also, if IBM enhances DB2 and thereby renders the Company's products
obsolete or devotes more resources to developing and marketing IBM's own DB2
tools, the Company's business, results of operations or financial condition
could be materially adversely affected.
 
 Dependence on Relationships with Relational Database Vendors
 
   The Company must develop and maintain close relationships with leading
database vendors to compete effectively. For example, the Company has entered
into alliances with Oracle Systems Corp., Sybase, Inc. and Informix Software,
Inc. If the Company fails to maintain existing relationships or establish new
relationships with database vendors, the Company's business, results of
operations and financial condition could be materially adversely affected.
 
 The Company's Net Losses and Its Ability to Satisfy Future Debt Obligations
 
   If the Company does not achieve its anticipated revenues and operating
income and continues to incur losses in the future, its ability to pay interest
on, or ultimately pay the principal amount of, its indebtedness could become
impaired. If it does not meet its cash requirements out of cash flow from
operations and available borrowings, it may not be able to obtain alternative
financing or may not be permitted to do so under the terms of its existing
financing arrangements. If it does not arrange for sufficient financing, its
ability to respond to changing business and economic conditions, to make future
acquisitions, to absorb adverse operating results or to fund capital
expenditures or increased working capital requirements may be adversely
affected. The Company could also become more vulnerable to industry downturns
and competitive pressures. See "--Liquidity and Capital Resources."
 
 Risks of International Sales
 
   In addition to the risks associated with foreign currency exchange rate
fluctuations, the Company is subject to other risks generally associated with
doing international business, including the following: (1) longer payment
cycles; (2) difficulty of managing remote offices; (3) greater difficulties in
accounts receivable collection; (4) burdens of complying with a wide variety of
foreign laws; and (5) exposure to general foreign economic declines and
political conditions.
 
 
                                       30

 Risks of Consulting Services Business
 
   The Company is subject to the risks associated with a consulting services
business, including (1) dependence on reputation with existing customers; (2)
volatility of workload; and (3) dependence on ability to attract and retain
qualified technical personnel. Also, the Company may derive a substantial
portion of its future consulting services revenue from the performance of
services under fixed-price contracts. The Company may not be able to perform in
a profitable manner under these contracts, particularly in the field of
software development, where cost overruns occur frequently.
 
 Dependence on Key Personnel
 
   The Company's success depends largely on the skills, experience and efforts
of its key management, marketing, product development, professional services
and operational personnel, including key personnel of acquired companies.
Because competition for qualified personnel in the software industry is
intense, the Company may face increasing difficulty in hiring, training and
integrating new employees and keeping current valued employees required for the
Company's continued growth. Further, certain key members of the management of
acquired companies may not continue with the combined businesses. If the
Company encounters difficulty in attracting and retaining key employees, the
Company's business, results of operations and financial condition could be
materially adversely affected. The Company's success depends in large part on
the skills and efforts of Andrew J. Filipowski, the Company's Chairman,
President and Chief Executive Officer, and Paul L. Humenansky, the Company's
Executive Vice President--Product Development and Chief Operations Officer. The
Company has not entered into non-competition agreements with Messrs. Filipowski
or Humenansky or any of its other key personnel and has not obtained "key man"
life insurance covering these individuals.
 
Recently Issued Accounting Pronouncements
 
   In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities." The Company is
required to adopt the provisions of SFAS No. 133 beginning with its March 31,
2000 interim financial statements. This statement provides a comprehensive
standard for the recognition and measurement of derivatives and hedging
activities. The Company is currently evaluating the impact of this standard on
its financial statements.
 
Quarterly Comparisons
 
   The following tables set forth an unaudited summary of quarterly financial
data. This quarterly information has been prepared on the same basis as the
annual consolidated financial statements and, in management's opinion, reflects
all adjustments necessary for a fair presentation of the information for the
periods presented. The operating results for any quarter are not necessarily
indicative of results for any future period.
 
   The Company has experienced a seasonal pattern in its operating results,
with the fourth quarter typically having the highest total revenues and
operating income in a given year. For example, 33%, 33% and 32% of the
Company's total revenues in 1998, 1997 and 1996, respectively, were generated
in the fourth quarter. Further, revenues from the fourth quarter of 1997 were
higher than the first quarter of 1998. The Company believes the seasonality of
its revenue results primarily from the budgeting cycles of its software product
customers and the structure of the Company's sales commission and bonus
programs. In addition, the Company's software products revenues may vary
significantly from quarter to quarter depending upon other factors, such as the
timing of new product announcements and releases by the Company and its
competitors.
 
                                       31
<PAGE>
 
The Company operates with relatively little backlog, and substantially all of
its software products revenues in each quarter result from sales made in that
quarter.

or misappropriation, to maintain or enhance its relationships with relational

statements to reflect new events or changed circumstances.
 
ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
 
   Interest Rate Risk--The Company is exposed to the impact of changes in
interest rates primarily due to the manner in which the Company manages its
investment portfolio. As stated in the Company's written policy, the goal of
the investment portfolio is preservation of principal and every effort is made
to limit default, market, liquidity and reinvestment risk. The vast majority of
the investment portfolio consists of money market instruments, corporate bonds
and asset backed securities. Speculative use of any security of any kind,
including derivative products, is prohibited in the investment portfolio.
 
                                       33
<PAGE>
 
   To mitigate risk associated with the investment portfolio, the Company
invests only in securities that have been rated as high quality by national
rating agencies. The vast majority of these securities have a maturity date
within six months. The portfolio is reviewed on a periodic basis, and
subsequently adjusted in the event that the credit rating of any security held
in the portfolio has deteriorated. Amounts invested with any one issuer are
limited to reduce default risk. Only securities with active secondary markets
are purchased to ensure future liquidity.
 
   Foreign Currency Exchange Risk--The Company conducts business on a global
basis through subsidiaries in multiple countries utilizing major international
currencies. The Company is, therefore, exposed to movement in currency exchange
rates. The Company continues to maintain a program, utilizing forward foreign
exchange contracts, designed to hedge currency exposures related to certain
nonfunctional assets and liabilities resulting from intercompany balances. By
written policy, the Company does not enter into any type of foreign exchange
contract for trading or speculative purposes.
 
   Gains and losses on the foreign exchange forward contracts are included in
other income and offset foreign exchange gains and losses from the revaluation
of intercompany balances denominated in currencies other than the functional
currency of the reporting entity. The forward contracts generally have a
maturity of one month and are executed only with major financial institutions.
 
   Equity Price Risk--The Company has several minimal investments in the
marketable equity securities of publicly traded companies. All of these
investments, as of December 31, 1998, were considered available-for-sale, with
any unrealized gains or losses deferred as a component of stockholders' equity.
The largest of these holdings was the Company's investment in Memco, with a
December 31, 1998 fair value of $16.6 million. All other equity investments are
immaterial.
 
   The Company utilizes a "Value-at-Risk" (VaR) model to determine the maximum
potential one-day loss in the fair value of its interest rate, foreign exchange
and equity price sensitive instruments. The VaR model estimates were made
assuming normal market conditions and a 95% confidence level. There are various
modeling techniques that can be used in the VaR calculations. The calculations
the Company performed were based on the variance-covariance statistical
modeling technique and included all interest rate sensitive instruments,
foreign exchange derivative contracts and equity investments. The VaR estimate
utilized historical interest rates, foreign exchange rates and equity prices
from the past year to estimate volatility and correlation of these rates and
prices in the future.
 
   As of December 31, 1998, the following amounts represented the potential
loss in fair value that the Company could incur from adverse changes in
interest rates, foreign exchange rates or equity prices for a one-day period.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1.  Summary of Significant Accounting Policies
 
 Nature of Operations
 
   PLATINUM technology International, inc. and its subsidiaries (collectively,
the "Company" or "PLATINUM") develop, market and support software products, and
provide related professional services, that help organizations manage and
improve their information technology ("IT") infrastructures, which consist of
data, systems and applications. The Company's products and services help IT
departments, primarily in large and data-intensive organizations, minimize
risk, improve service levels and leverage information to make better business
decisions. The Company's products typically perform fundamental functions such
as automating operations, maintaining the operating efficiency of systems and
applications and ensuring data access and integrity. The Company markets and
supports its products and services principally through its own sales
organization, including an international network of wholly-owned subsidiaries.
Throughout 1998, the Company's software segment was organized into four
business units consisting of database management, systems management,
application infrastructure management, and data warehousing and decision
support.
 
 Use of Estimates
 
   In preparing the consolidated financial statements in conformity with
generally accepted accounting principles, the Company's management makes
estimates and assumptions that affect the reported amounts of assets and
liabilities and 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.
 
 Principles of Consolidation
 
   The consolidated financial statements include the accounts of the Company
and its subsidiaries. All intercompany accounts and transactions are eliminated
in consolidation.
 
 Revenue Recognition
 
    Revenues from software product sales of perpetual and fixed-term license
agreements are recognized upon product delivery and customer acceptance, when
all significant contractual obligations are satisfied and the collection of the
resulting receivables is reasonably assured. Software product sales under
extended payment terms are discounted to present value. Revenues from
maintenance fees implicit in software product sales or separately priced
maintenance agreements are recognized on a straight-line basis over the
maintenance period.
 
   Professional service revenues are derived from the Company's consulting
services business and educational programs. These revenues are comprised of
both time and material contracts and fixed-price contracts. Time and material
contract revenues are recognized as services are performed. Fixed-price
contract revenues are recognized based on the percentage-of-completion method.
 
   On January 1, 1998, the Company adopted AICPA Statement of Position ("SOP")
97-2, "Software Revenue Recognition," which specifies the criteria that must be
met for 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.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 
 Cash Equivalents and Investment Securities
 
   Cash equivalents are comprised of highly liquid investments with original
maturities of three months or less. Investment securities consist primarily of
corporate bonds with original maturities of less than one year, mortgage-backed
and other asset-backed securities with original maturities generally ranging
from three to thirty years, and marketable equity securities. The Company
classifies its investment securities as either available-for-sale or trading
and reports them at fair value. The consolidated financial statements reflect
investment securities classified as held-to-maturity which were acquired
through the Company's acquisition of Mastering, Inc. ("Mastering"), as
discussed in Note 2.
 
   Available-for-sale securities represent those securities that do not meet
the classification of held-to-maturity and are not actively traded. Trading
securities represent those securities which the Company intends to buy or sell
in the near term for the purpose of generating profits on increases in market
values. For available-for-sale securities, unrealized holding gains and losses,
net of income taxes, are reported as a separate component of stockholders'
equity. For trading securities, unrealized holding gains and losses are
reflected in pre-tax earnings. For securities transferred from available-for-
sale to the trading classification, any unrealized holding gains or losses at
the date of transfer are recognized in pre-tax earnings immediately.
 
 Property and Equipment
 
   Property and equipment are stated at cost. Depreciation is computed using
the straight-line method based on the estimated useful lives, generally three
to seven years, of the various classes of property and equipment. Amortization
of leasehold improvements is computed over the shorter of the lease term or the
estimated useful life of the asset.
 
 Purchased and Developed Software
 
   Software development costs are accounted for 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." Costs associated
with the planning and designing phase of software development, including coding
and testing activities necessary to establish technological feasibility, are
classified as product development and expensed as incurred. Once technological
feasibility has been determined, additional costs incurred in development,
including coding, testing and documentation, are capitalized.
 
   Amortization of purchased and developed software is provided on a product-
by-product basis over the estimated economic life of the software, generally
four years, using the straight-line method. This method generally results in
greater amortization expense per year than the method based on the ratio of
current year gross product revenue to current and anticipated future gross
product revenue. Amortization commences when a product is available for general
release to customers. Unamortized capitalized costs determined to be in excess
of the net realizable value of a product are expensed at the date of such
determination.
 
 Excess of Cost Over Net Assets Acquired
 
   Excess of cost over net assets acquired is amortized on a straight-line
basis over the expected period to be benefited, generally seven to 15 years.
Adjustments to the carrying value of excess of cost over net assets acquired
are made if the sum of expected future net cash flows from the business
acquired is less than book value.
 
 Income Taxes
 
   Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to temporary differences between the financial
statement carrying amounts of existing assets and liabilities and their
 
                                      F-7
<PAGE>
 
            PLATINUM technology International, inc. AND SUBSIDIARIES
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 
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. The effect on deferred tax assets and
liabilities of a change in tax rates is recognized in earnings in the period of
enactment.
 
 Fair Value of Financial Instruments and Long-Lived Assets
 
   The Company has reviewed the following financial instruments and determined
that their fair values approximated their carrying values as of December 31,
1998 and 1997: cash and cash equivalents; trade and installment receivables;
accrued interest and other current assets; refundable income taxes;
acquisition-related payables; accounts payable and other accrued liabilities;
and long-term obligations, excluding convertible subordinated notes. Investment
securities are discussed in Note 3, and convertible subordinated notes are
discussed in Note 12.
 
   On January 1, 1996, the Company adopted SFAS No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of,"
under which the Company has reviewed long-lived assets and certain intangible
assets and determined that their carrying values as of December 31, 1998 are
recoverable in future periods.
 
 Earnings Per Share
 
   In the fourth quarter of 1997, the Company 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 with basic ("Basic") and 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. Because the Company
reported a net loss for the years ended December 31, 1998, 1997 and 1996, per
share amounts have been presented under the Basic method only.
 
   Had the Company reported net income for the years ended December 31, 1998,
1997 and 1996, the weighted average number of shares outstanding would have
potentially been diluted by the following common equivalent securities (not
including the effects of applying the treasury stock method to outstanding
stock options or the if-converted method to convertible securities):

   Additionally, net income applicable to common stockholders for the years
ended December 31, 1998, 1997 and 1996 would have been increased by adding back
interest expense, net of income taxes, related to the convertible subordinated
notes of $11,994,000, $5,870,000 and $501,000, respectively.
 
 Foreign Currency Translation and Transactions
 
   The financial position and results of operations of the Company's foreign
subsidiaries are measured using the local currency as the functional currency.
Accordingly, assets and liabilities are translated into U.S. dollars

using current exchange rates as of the balance sheet date. Revenues and
expenses are translated at average exchange rates prevailing during the year.
Translation adjustments arising from differences in exchange rates are included
as a separate component of stockholders' equity. Gains and losses resulting
from foreign currency transactions are included in the consolidated statement
of operations.
 
 Derivative Financial Instruments
 
   In the ordinary course of business, the Company enters into forward exchange
contracts to minimize the short-term impact of foreign currency fluctuations on
assets and liabilities denominated in currencies other than the functional
currency of the reporting entity. All foreign exchange forward contracts
designated and effective as hedges of firm commitments are treated as hedges.
 
   Forward exchange contracts are reported at fair value within short-term
investment securities. Fair values of forward exchange contracts are determined
using published rates. Gains and losses on the forward exchange contracts are
included in other income and expense and offset foreign exchange gains and
losses from the revaluation of intercompany balances denominated in currencies
other than the functional currency of the reporting entity. Realized and
unrealized holding gains and losses on the forward exchange contracts are
reported within operating activities in the statement of cash flows.
 
 Stock-Based Compensation
 
   On January 1, 1996, the Company adopted SFAS No. 123, "Accounting for Stock-
Based Compensation," which permits entities to recognize the compensation
expense associated with the fair value of all stock-based awards on the date of
grant. Alternatively, SFAS No. 123 allows entities to continue to apply the
provisions of Accounting Principles Board ("APB") Opinion No. 25, "Accounting
for Stock Issued to Employees," and provide pro forma disclosures as if the
fair value method defined in SFAS No. 123 had been applied. The Company has
elected to apply the provisions of APB Opinion No. 25 and provide the pro forma
disclosures of SFAS No. 123.
 
 Transfers and Servicing of Financial Assets and Extinguishments of Liabilities
 
   On January 1, 1997, the Company adopted SFAS No. 125, "Accounting for
Transfers and Servicing of Financial Assets and Extinguishments of
Liabilities," which distinguishes transfers of financial assets that are sales
from transfers that are secured borrowings. The Company sells installment
receivables to third party finance companies in the normal course of business.
During 1998, all such transactions were accounted for as sales in accordance
with SFAS No. 125.
 
 Supplemental Cash Flow Disclosure
 
   Income tax refunds received by the Company amounted to $445,000, $524,000
and $307,000 in 1998, 1997 and 1996, respectively. Cash paid for income taxes
in 1998, 1997 and 1996 was $1,180,000, $2,877,000 and $3,642,000, respectively.
Cash paid for interest in 1998, 1997 and 1996 was $18,101,000, $8,603,000 and
$1,206,000, respectively.

shares of Common Stock. The Company did not restate the consolidated financial
statements to reflect the results of Vayda for the periods preceding the

developer of internet commerce web sites, in exchange for 204,173 shares of
Common Stock, which had a Market Value of approximately $5,400,000 at the time
of the acquisition. In addition, the Company assumed stock options which
converted into options to purchase 77,267 shares of Common Stock. The Company
did not restate the consolidated financial statements to reflect the results of
Vivid for the periods preceding the acquisition. As a result, the retained
earnings of Vivid were recorded as of the acquisition date, causing a
$3,522,000 addition to the Company's accumulated deficit in 1998. This
adjustment is reflected in the consolidated statements of stockholders' equity.
 
 Purchase Transactions
 
   The Company has also made a number of acquisitions that have been accounted
for under the purchase method. Accordingly, purchase prices have been allocated
to identifiable tangible and intangible assets acquired and liabilities assumed
based on their estimated fair values. Amounts allocated to acquired in-process
technology have been expensed at the time of acquisition. Excess of cost over
net assets acquired is amortized on a straight-line basis over the expected
period to be benefited, generally seven to 15 years. The consolidated
statements of operations reflect the results of operations of the purchased
companies since the effective dates of the acquisitions.
 
   To determine the fair market value of the acquired in-process technology,
the Company considered the three traditional approaches of value: the cost
approach, the market approach and the income approach. The Company relied
primarily on the income approach, whereupon fair market value is a function of
the future revenues expected to be generated by an asset, net of all allocable
expenses and charges for the use of contributory assets. The future net revenue
stream is discounted to present value based upon the specific level of risk
associated with achieving the forecasted asset earnings. The income approach
focuses on the income producing capability of the acquired assets and best
represents the present value of the future economic benefits expected to be
derived from these assets.
 
   The Company determined that the acquired in-process technologies had not
reached technological feasibility based on the status of design and development
activities that required further refinement and testing. The development
activities required to complete the acquired in-process technologies included
additional coding, cross-platform porting and validation, quality assurance
procedures and customer beta testing.
 
   The acquired technologies represent unique and emerging technologies, the
application of which is limited to the Company's IT infrastructure strategy.
Accordingly, these acquired technologies have no alternative future use other
than the use for which the technologies were designed.
 
   Effective January 1996, the Company acquired all of the outstanding capital
stock of Advanced Systems Technologies, Inc. ("AST"), a leading developer of
performance management tools, in exchange for approximately $445,000 in cash
plus 344,640 shares of Common Stock, which had a Market Value of approximately
$5,800,000 at the time of the acquisition.

banking and other professional fees, write-downs of certain assets, employee
severance payments, costs of closing excess office facilities and various other

certain operating results by such businesses. The amount of these payments was
not determinable at December 31, 1998. Additional payments will be charged to

   During 1998 and 1997, the Company reclassified certain available-for-sale
securities to trading because the Company intended to sell the securities at
various dates in the near future to benefit from increases in the market price
of those securities. Unrealized holding gains from reclassified securities of
approximately $10,149,000, previously reported as a separate component of
stockholders' equity in the amount of $6,089,000 (net of income taxes), were
recognized in pre-tax earnings for the year ended December 31, 1998. Unrealized
holding gains from reclassified securities of approximately $19,829,000,
previously reported as a separate component of stockholders' equity in the
amount of $11,897,000 (net of income taxes), were recognized in pre-tax
earnings for the year ended December 31, 1997. The Company sold a portion of
its trading securities during 1998 and 1997 and consequently reclassified the
corresponding unrealized gains to realized gains.
 
   During 1998, the Company transferred its trading securities to available-
for-sale because the Company no longer had the intent to sell such securities
in the near future.

   Installment accounts receivable represent amounts collectible on long-term
financing arrangements and include fees for product licenses, upgrades and
maintenance, sometimes also bundled with professional services contracts.
Installment receivables are generally financed over three to five years and are
recorded net of unamortized discounts, deferred maintenance fees and allowances
for uncollectible amounts.
 
   The Company sells a significant portion of its installment receivables to
third parties. When these receivables are sold, the Company reduces the gross
installment receivable balance. Additionally, the Company reclassifies the
deferred maintenance to an obligation, which was previously reflected as a
reduction of the related installment receivable balance. The deferred
maintenance is recognized ratably into income over the term of the maintenance
agreement.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 
 
   Proceeds from the sale of installment receivables for 1998, 1997 and 1996
were approximately $319,782,000, $206,916,000 and $129,328,000, respectively.
There were no accounts receivable sold with recourse for the years ended
December 31, 1998 and 1997. As of December 31, 1998 and 1997, there were no
potential recourse obligations for accounts receivable sold with recourse
previous to 1997.
 
   The Company has an agreement with a third party that provides for potential
recourse obligations in the form of a loss pool based on the performance of the
related accounts receivable portfolio. Based on the terms of that agreement,
potential recourse obligations at December 31, 1998 were approximately
$20,000,000. Based on the credit ratings of the underlying obligors to the
accounts receivable and the performance history of the accounts receivable
portfolio, the Company has assessed the exposure related to these recourse
obligations and does not expect the potential liability to have a material
adverse effect on the Company's future results of operations.
 
7. Employee Benefit Plans
 
   The Company has various defined contribution retirement plans (401(k) and
profit sharing) for qualified employees. Employer contributions made under the
plans totaled $4,766,000, $1,846,000 and $1,189,000 in 1998, 1997 and 1996,
respectively.
 
8. Lines of Credit
 
   At December 31, 1998, the Company had an unsecured bank line of credit for
an aggregate of $65,000,000, under which borrowings bear interest at rates
ranging from approximately LIBOR plus 1.25% to the bank's prime rate. This line
of credit is subject to limitations based upon certain financial covenants. At
December 31, 1998, there were no borrowings outstanding under this line of
credit. Additionally, the Company has a line of credit with a Japanese bank for
approximately $2,152,000 (based upon current exchange rates), under which
borrowings bear interest at a rate of 2.125%. As of December 31, 1998, the
Company had outstanding borrowings of approximately $1,197,000 under this line
of credit.
 
   At December 31, 1998, the Company had aggregate letters of credit
outstanding for approximately $6,383,000, with expiration dates ranging from
February 1999 to April 2000. These letters of credit reduce the balance
available under the lines of credit.
 
9. Stock Options and Employee Stock Purchase Plan
 
   As of December 31, 1998, the Company had seven stock option plans, which are
described below, as well as several plans that have been assumed pursuant to
acquisitions. The Company applies APB Opinion No. 25 in accounting for its
plans. Accordingly, no compensation cost has been recognized for its fixed
stock option plans and its employee stock purchase plan (the "Stock Purchase
Plan").
 
   Had compensation cost for the Company's stock option plans and the Stock
Purchase Plan been determined consistent with SFAS No. 123, the Company's net
loss and net loss per share would have been the pro forma amounts indicated
below for the years ended December 31, 1998, 1997 and 1996:

   Under SFAS No. 123, the pro forma compensation expense related to the
Company's stock option plans and Stock Purchase Plan, before effects for income
taxes, was approximately $46,500,000, $23,575,000 and $13,775,000 in 1998, 1997
and 1996, respectively.
 
   Excluding stock option plans assumed pursuant to acquisitions, the Company
has seven stock option plans ("Company Plans"). The Employee Incentive
Compensation Plan, 1994 Stock Incentive Plan, 1991 Option Plan, 1989 Option
Plan and the 1998 Broad Based Option Plan provide for the granting of options
to employees for up to an aggregate of 36,160,000 shares. The Chief Executive
Option Plan provides for the granting of options for up to 1,600,000 shares to
the Company's Chief Executive Officer and President. Under the Directors'
Option Plan, the Company may grant options for up to 500,000 shares to non-
employee directors.
 
   In general, the options granted under the Company Plans, excluding the
Directors' Option Plan, during 1998, 1997 and 1996, have similar provisions.
Under these plans, the Company has granted both non-qualified and incentive
stock options, with the exception of the 1998 Broad Based Plan which granted
only non-qualified stock options. Options granted under the Company Plans,
excluding the Directors' Option Plan, have an exercise price equal to the
closing market price of the Company's stock on the date of grant, have a legal
life of ten years, and typically vest in equal annual installments over a four-
year period beginning one year from the date of grant. Certain options granted
prior to 1995 have a legal life of fifteen years. The specific provisions of
any grant are determined by the Compensation Committee of the Board of
Directors or another designated committee.
 
   Under the Directors' Option Plan, only non-qualified options have been
granted. These options have an exercise price equal to the closing market price
of the Company's stock on the date of grant and have a legal life of ten years.
The options granted in 1995 under this plan vested immediately, while those
granted in 1996, 1997 and 1998 vest annually over a three-year period beginning
one year from the date of grant.
 
   As discussed in Note 2, the Company has assumed various option grants
related to certain acquisitions. The assumption of these option grants resulted
in the deemed issuance by the Company of options for 3,861,832, 1,603,835 and
1,723,316 shares in 1998, 1997 and 1996, respectively. The options assumed
reflect outstanding options at the time of acquisition. The provisions of the
assumed options are generally the same as those provided for in the original
option agreements.
 
   In 1996, the Company began offering the Stock Purchase Plan to its employees
who work more than 20 hours per week. Under this plan, the Company is
authorized to issue up to 5,000,000 shares (excluding shares assumed to be
issued pursuant to acquisitions) of Common Stock. Under terms of the Stock
Purchase Plan and current policies of the administrative committee, employees
may elect each year to withhold between one and 50 percent of their cash
compensation through regular payroll deductions to purchase Common Stock,
subject to Internal Revenue Service limitations. The purchase price of the
stock is 85 percent of the lower of the price at the grant date, which is the
beginning of the plan year (March 1, or September 1 for employees with a start
date between March 1 and August 31) or the exercise date, which is the end of
each plan quarter (February 28, May 31, August 31 and November 30). As of
December 31, 1998, approximately 59% of eligible employees were participating
in the Stock Purchase Plan. Under the Stock Purchase Plan, the Company sold
1,585,766, 985,755 and 281,725 shares to employees in 1998, 1997 and 1996,
respectively (including amounts relating to acquired companies).
 
   The fair value of the stock option grants is estimated using the Black-
Scholes option-pricing model, with the following weighted-average assumptions
used for stock option grants in 1998, 1997 and 1996, respectively: weighted
average option price, which equals the fair market value at date of grant, of
$20.24, $14.96 and $14.24; expected dividend yields of 0% for all years;
expected volatility of 64%, 61% and 55%; risk-free

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 
interest rates of 4.66%, 5.66% and 6.37%; and an expected life of five years
for all years. The fair value of the employees' purchase rights pursuant to
the Stock Purchase Plan are estimated using the Black-Scholes option-pricing
model, with the following weighted-average assumptions used for purchase
rights granted in 1998, 1997 and 1996, respectively: average fair market value
of $22.67, $13.75 and $10.75; average option price of $15.36, $11.69 and
$9.14; expected dividend yield of 0% for each year; expected volatility of
64%, 61% and 55%; average risk-free interest rate of 4.69%, 5.52% and 5.42%;
and expected life of three months for each year.
 
   Stock option plan activity during the years ended December 31, 1998, 1997
and 1996 was as follows:

10. Preferred Stock
 
   On December 23, 1997, the Company agreed, pursuant to a stock purchase
agreement, to issue to Intel 1,768,421 shares of its Preferred Stock, which
had a fair market value of approximately $42,000,000 on the date of
subscription, in exchange for certain product technologies and other
intangible assets. The shares of Preferred Stock were subscribed for as of
December 31, 1997 and subsequently issued on January 14, 1998.
 
   The holders of the Preferred Stock have the option to convert, at any time,
each share of Preferred Stock into one share of Common Stock. Each share of
Preferred Stock will automatically convert into one share of Common Stock upon
the transfer by any holder of Preferred Stock in a non-permitted transfer. In
the event of a liquidation of the Company, the holders of the Preferred Stock
are entitled to receive $23.75 per share plus the amount of any declared but
unpaid dividends. The conversion and liquidation terms are subject to
adjustment based upon subsequent changes in equity interests.

   The net change in the valuation allowance during 1998, 1997 and 1996 was an
increase of $7,750,000, $43,365,000 and $18,490,000, respectively.
 
   The Company has reduced gross deferred tax assets by a valuation allowance
to reflect the estimated amount of deferred tax assets which will, more likely
than not, be realized. The net deferred tax asset at December 31, 1998 reflects
management's estimate of the amount that will be realized as a result of future
profitability. The amount of the deferred tax asset considered realizable could
be reduced if estimates of future taxable income are reduced.
 
   At December 31, 1998, the Company had approximately $333,270,000 of net
operating loss carryforwards and $10,574,000 of tax credit carryforwards, which
are available to reduce future Federal income taxes, if any. The net operating
loss carryforwards expire between 2004 and 2018. The tax credit carryforwards
expire between 2002 and 2018. The Company's ability to utilize the net
operating loss carryforwards and available tax credits may be limited due to
changes in ownership as a result of business combinations.
 
12. Convertible Subordinated Notes
 
   In November 1996, the Company issued $115,000,000 of convertible
subordinated notes (the "1996 Notes") due November 15, 2001, bearing interest
at 6.75% annually. Interest is payable semi-annually on May 15 and November 15.
The holders of the Notes have the option to convert them into shares of Common
Stock, at any time prior to maturity, at a conversion price of $13.95 per
share. The Notes are redeemable at the option of the Company, in whole or in
part, at any time during the twelve-month period commencing November 15, 1999
at 102.7% of their principal amount and during the twelve-month period
commencing November 15, 2000

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 
at 101.35% of their principal amount. During 1998 and 1997, $36,000 and
$10,000, respectively, of the 1996 Notes were converted to Common Stock. As of
December 31, 1998, $114,954,000 of the 1996 Notes were outstanding.
 
   The Company estimated the fair value of the 1996 Notes as of December 31,
1998 and 1997 at approximately $170,132,000 and $236,879,000, respectively,
based upon their trading price on the Nasdaq SmallCap Market on that date.
 
   In December 1997, the Company issued $150,000,000 of convertible
subordinated notes (the "1997 Notes") due December 15, 2002, bearing interest
at 6.25% annually. Interest is payable semi-annually on June 15 and December
15, commencing June 15, 1998. The holders of the 1997 Notes have the option to
convert them into shares of Common Stock, at any time prior to maturity, at a
conversion price of $36.05 per share. The 1997 Notes are redeemable at the
option of the Company, in whole or in part, at any time during the twelve-month
period commencing December 15, 2000 at 102.5% of their principal amount and
during the twelve-month period commencing December 15, 2001 at 101.25% of their
principal amount. As of December 31, 1998, $150,000,000 of the 1997 Notes were
outstanding.
 
   The Company estimated the fair value of the 1997 Notes as of December 31,
1998 and 1997 at approximately $131,820,000 and $159,375,000, respectively,
based upon their bid price in the convertible debentures market on that date.
 
   For the years ended December 31, 1999, 2000, 2001 and 2002, aggregate annual
maturities of the 1996 Notes and the 1997 Notes are $0, $0, $114,954,000 and
$150,000,000, respectively.
 
13. Restructuring
 
   In August 1996, the Company's wholly-owned subsidiary, LBMS (acquired as of
May 12, 1998), executed a plan to restructure its operations. During the second
half of 1996, LBMS recorded a restructuring charge of $14,109,000, net of
$3,512,000 in sublease rentals and recoveries from the sale of a product line.
The restructuring charge was comprised primarily of abandoned lease costs,
severance and other personnel costs and write-offs of excess equipment and
other assets. During 1997, LBMS recorded a restructuring benefit of $1,490,000
related to sublease rental activity. This benefit was offset against the
Company's restructuring charge recorded in 1997, as discussed below.
 
   In the fourth quarter of 1996, the Company's wholly-owned subsidiary, Logic
Works (acquired as of May 28, 1998), implemented a restructuring plan to
streamline its operations by reducing its workforce, consolidating and
reorganizing certain operations and writing off certain fixed assets and other
impaired assets. The plan included the closing and moving of several offices
and the termination of approximately 25 employees across all departments. Logic
Works recorded a charge of $2,203,000 relating to this restructuring.
 
   In May 1997, the Company executed a restructuring plan to consolidate its
sales, marketing, business development and product development operations to
achieve cost efficiencies through the elimination of redundant functions. These
redundancies resulted primarily from businesses acquired over the previous
three years. The Company also realigned its business units and inside sales
force to redirect focus on its strongest product lines and better integrate the
efforts of certain product development teams. As part of the plan, the Company
reduced its worldwide work force by approximately 10%, eliminating
approximately 400 positions primarily in the areas of product development and
support, marketing and inside sales and, to a lesser extent, professional
services and administration.
 
   The Company recorded a restructuring charge of $57,319,000 during the second
quarter of 1997 related to the restructuring plan. The restructuring charge
included the following expenses: facility-related costs, including

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 
a reserve for estimated lease obligations associated with the closing of office
facilities; write-offs of excess equipment, furniture and fixtures; write-offs
of capitalized software costs and other intangible assets related to the
termination of development efforts for certain discontinued products, as well
as penalties for the cancellation of distributorship agreements for such
products; and severance and other employee-related costs of the terminated
staff.
 
   During 1998, the Company recognized a restructuring benefit of $10,964,000
related to the Company's occupation of previously vacated facilities and the
relief of obligations under cancelled lease agreements, as well as sublease
rental activity. This restructuring benefit represents the recovery of certain
restructuring charges recorded by the Company in the second quarter of 1997, as
discussed above.
 
   The following table summarizes the Company's restructuring activity for the
years ended December 31, 1998 and 1997:

14. Derivative Financial Instruments
 
   The Company conducts business on a global basis in numerous major
international currencies and is, therefore, exposed to adverse movements in
foreign currency exchange rates. The Company has established a foreign currency
hedging program utilizing forward foreign exchange contracts to reduce certain
currency exposures. These contracts hedge exposures associated with
nonfunctional currency assets and liabilities denominated in Japanese,
Australian, Canadian, numerous Asian and various European currencies. At the
present time, the Company hedges only those currency exposures associated with
certain nonfunctional currency assets and liabilities resulting from
intercompany balances and does not generally hedge anticipated foreign currency
cash flows. The Company does not enter into forward exchange contracts for
trading purposes.

   Gains and losses on the foreign currency forward exchange contracts are
included in other income and offset foreign exchange gains and losses from the
revaluation of intercompany balances denominated in currencies other than the
functional currency of the reporting entity. The Company's forward contracts
generally have original maturities of one month.
 
   The table below provides information as of December 31, 1998 about the
Company's foreign currency forward exchange contracts, including notional
values of outstanding forward contracts purchased and sold and the unrealized
gains or losses recorded for each contract.

   While the notional or contract amounts of the Company's forward exchange
contracts provide one measure of the volume of these transactions, they do not
represent the Company's full exposure to credit risk. The Company faces
additional risks if the banking counterparties are unable to meet the terms of
the agreements. The Company has established policies to minimize such risks and
will only execute forward exchange contracts with major financial institutions.
The Company has assessed the potential exposure related to default by such
institutions to be minimal.

19. Subsequent Events
 
   Effective January 1, 1999, the Company reorganized its legal structure into
a holding company structure, under which the operations of the Company are
conducted through direct and indirect wholly-owned subsidiaries. Certain of
these subsidiaries, including PLATINUM technology IP, inc. and PLATINUM
technology, inc. (collectively, the "Obligor Subsidiaries") commenced
substantive operations. The corporate structural changes were made to reflect
the Company's global focus and to provide greater operational flexibility, as
well as allow for more efficient tax planning in the future. The Obligor
Subsidiaries were established with de minimis capitalizations from the Company
as of December 31, 1998. The Obligor Subsidiaries are joint and several
obligors on the 1996 Notes and the 1997 Notes previously issued by the Company.
There are currently no significant restrictions on the Company's ability to
obtain funds from the Obligor Subsidiaries.
 
   On February 22, 1999, the Company announced a restructuring plan to
streamline operations, increase profitability, and deliver greater value to
customers and shareholders. The Company believes that this restructuring plan
will yield approximately $90 million (unaudited) in annual savings and
significantly increase operating margins. As a result of these actions, the
Company expects to incur a one-time charge of approximately $90 to $110 million
(unaudited) in the first quarter of 1999.
 
   On March 29, 1999, the Company acquired all of the outstanding ordinary
shares of Memco Software, Ltd. ("Memco"), a leading provider of information
security software, in exchange for 13,751,923 shares of the Company's Common
Stock. The Company also assumed Memco stock options which converted into
options to purchase 3,279,498 shares of the Company's Common Stock. This
transaction is expected to be accounted for as a pooling of interests. Costs
incurred in connection with this transaction will be expensed in the first
quarter of 1999.

   On March 29, 1999, the Company and Computer Associates International, Inc.
("CA") announced the execution of a merger agreement pursuant to which CA has
agreed to acquire the Company through a cash tender offer. Under the terms of
the merger agreement, a wholly-owned subsidiary of CA will offer to purchase
all outstanding shares of the Company's Common Stock for $29.25 per share.
Consummation of the tender offer is subject to certain conditions, including
the condition that at least a majority of the outstanding shares of the
Company's Common Stock be tendered and not withdrawn. Consummation of the
tender offer is also subject to the expiration or termination of any applicable
antitrust waiting period. Following completion of the tender offer and subject
to certain conditions, the Company will merge into the subsidiary of CA, with
the Company surviving as a wholly-owned subsidiary of CA. The transactions are
currently expected to be completed in mid-1999.

                          INDEPENDENT AUDITORS' REPORT
 
The Stockholders and Board of Directors
PLATINUM technology International, inc.:
 
   We have audited the accompanying consolidated balance sheets of PLATINUM
technology International, inc. and subsidiaries as of December 31, 1998 and
1997 and the related consolidated statements of operations, comprehensive loss,
stockholders' equity, and cash flows for each of the years in the three-year
period ended December 31, 1998. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements based on our audits. We did
not audit the financial statements of Mastering, Inc. and Logic Works, Inc.,
wholly-owned subsidiaries, which statements reflect total assets constituting
13 percent in 1997, and total revenues constituting 12 percent and 12 percent
in 1997 and 1996, respectively, of the related consolidated totals. Those
statements were audited by other auditors whose reports have been furnished to
us and our opinion, insofar as it relates to the amounts for Mastering, Inc.
and Logic Works, Inc., is based solely on the reports of the other auditors.
 
   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 and the reports of the other
auditors provide a reasonable basis for our opinion.
 
   In our opinion, based on our audits and the reports of the other auditors,
the consolidated financial statements referred to above present fairly, in all
material respects, the financial position of PLATINUM technology International,
inc. and subsidiaries as of December 31, 1998 and 1997, and the results of
their operations and their cash flows for each of the years in the three-year
period ended December 31, 1998, in conformity with generally accepted
accounting principles.

The Stockholders and Board of Directors of
PLATINUM technology International, inc.:
 
   Under date of February 8, 1999 (except as to Note 19, which is as of March
29, 1999), we reported on the consolidated balance sheets of PLATINUM
technology International, inc. and subsidiaries as of December 31, 1998 and
1997, and the related consolidated statements of operations, comprehensive
loss, stockholders' equity and cash flows for each of the years in the three-
year period ended December 31, 1998, as contained in the 1998 annual report to
stockholders. These consolidated financial statements and our report thereon
are included in the annual report on Form 10-K for the year ended December 31,
1998. Our report is based in part on the reports of other auditors. In
connection with our audits of the aforementioned consolidated financial
statements, we also audited the related consolidated financial statement
schedule. The financial statement schedule is the responsibility of the
Company's management. Our responsibility is to express an opinion on the
financial statement schedule based on our audits.
 
   In our opinion, based on our audits and the reports of the other auditors,
such consolidated 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.

                            SEVERANCE PAY AGREEMENT
                            -----------------------


     This Severance Pay Agreement ( this "Agreement") is made and entered into
as of the 31st  day of August, 1998 by and between PLATINUM technology, inc., a
Delaware corporation (together with its subsidiaries, the "Company"), and Tom A.
Slowey (the "Executive").

                                   WITNESSETH
                                   ----------

     WHEREAS, Executive has certain unique expertise, skills, contacts and
experience relating to the Company's business;

     WHEREAS, Executive is currently employed by the Company and the Company
believes that the continuation of such employment is material to the continued
success of the Company;

     WHEREAS, in light of the fact that the Company is publicly-held, the
Company recognizes and acknowledges that it is necessary, to retain Executive,
to provide certain security to Executive in the event that a Change in Control
(as defined below) of the Company should occur; and

     WHEREAS, to that end, the Company desires to provide for severance pay to
Executive in the event that Executive's employment with the Company is
terminated in connection with or as a result of a Change in Control, on the
terms and conditions set forth herein.

     NOW, THEREFORE, in consideration of the mutual covenants and agreements
contained herein, and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereby agree as
follows:

1.   Certain Definitions.  As used in this Agreement the following initially
capitalized terms shall have the following meanings:

     a.  Severance Pay Rate:  The annual rate of compensation payable by the
Company to Executive as severance pay, which shall be equal to the sum of the
greatest amount of each of (i) the base salary plus (ii) the incentive
compensation, respectively, paid to Executive during any trailing 12 month
period or periods (it being expressly understood that the 12 month periods
utilized to determine base salary and incentive compensation may be different)
during the 36 month period preceding termination of Executive's employment with
the Company; provided, however, if Executive's annual base salary rate at the
time of termination is greater than his base salary in the greatest trailing 12
month period, then such annual base salary rate shall be utilized for purposes
of this Section 1(a).

     b.  Payout Period:  A period of 36 months from the effective date of the
termination of Executive's employment with the Company.

                                       1
<PAGE>
 
     c.  Bonus Amount:  The product of (1) the higher of (i) the annual bonus
paid or payable, including by reason of any deferral, to the Executive by the
Company or its affiliate companies for the most recently completed fiscal year
prior to termination of Executive's employment with the Company, or (ii) the
average annualized (for any fiscal year consisting of less than twelve full
months) bonus paid or payable to the Executive by the Company or its affiliated
companies in respect of the three fiscal years immediately preceding the fiscal
year in which the Change in Control occurs, or (iii) Executive's targeted annual
bonus for the fiscal year in which the Change in Control occurs and (2) a
fraction, the numerator of which is the number of days in the current fiscal
year through the date on which Executive's employment is terminated, and the
denominator of which is 365.

     d.  Aggregate Severance Pay: The sum of (1) the Bonus amount, plus (2)
the product obtained by multiplying: (i) the Severance Pay Rate divided by
twelve; by (ii) the number of months in the applicable Payout Period.

     e.  Change in Control:  The first to occur of the following:

          1.   The acquisition by any individual, entity or group (within the
               meaning of Section 13(d)(3) or 14(d)(2) of the Securities
               Exchange Act of 1934, as amended (the "Exchange Act")) (a
               "Person") of beneficial ownership (within the meaning of Rule
               13d-3 promulgated under the Exchange Act) of twenty percent (20%)
               or more of either (A) the then-outstanding shares of common stock
               of the Company (the "Outstanding Company Common Stock") or (B)
               the combined voting power of the then-outstanding voting
               securities of the Company entitled to vote generally in the
               election of directors (the "Outstanding Company Voting
               Securities"); provided, however, that for purposes of this
               subsection (i), the following acquisitions shall not constitute a
               Change in Control: (A) any acquisition directly from the Company
               other than in connection with the acquisition by the Company or
               its affiliates of a business, (B) any acquisition by the Company,
               (C) any acquisition by any employee benefit plan (or related
               trust) sponsored or maintained by the Company or any corporation
               controlled by the Company, (D) any acquisition by a lender to the
               Company pursuant to a debt restructuring of the Company, or (E)
               any acquisition by any corporation pursuant to a transaction
               which complies with clauses (A), (B) and (C) of subsection (3) of
               this Section 1(e);

                                       2
<PAGE>
 
          2.   Individuals who, as of the date hereof, constitute the Board (the
               "Incumbent Board") cease for any reason to constitute at least a
               majority of the Board; provided, however, that any individual
               becoming a director subsequent to the date hereof whose election,
               or nomination for election by the Company's shareholders, was
               approved by a vote of at least a majority of the directors then
               comprising the Incumbent Board shall be considered as though such
               individual were a member of the Incumbent Board, but excluding,
               for this purpose, any such individual whose initial assumption of
               office occurs as a result of an actual or threatened election
               contest with respect to the election or removal of directors or
               other actual or threatened solicitation of proxies or consents by
               or on behalf of a Person other than the Board;

          3.   Consummation of a reorganization, merger or consolidation of the
               Company or any direct or indirect subsidiary of the Company or
               sale or other disposition of all or substantially all of the
               assets of the Company (a "Business Combination"), in each case,
               unless, following such Business Combination, (A) all or
               substantially all of the individuals and entities who were the
               beneficial owners, respectively, of the Outstanding Company
               Common Stock and Outstanding Company Voting Securities
               immediately prior to such Business Combination beneficially own,
               directly or indirectly, more than sixty percent (60%) of,
               respectively, the then-outstanding shares of common stock and the
               combined voting power of the then outstanding voting securities
               entitled to vote generally in the election of directors, as the
               case may be, of the corporation resulting from such Business
               Combination (which shall include for these purposes, without
               limitation, a corporation which as a result of such transaction
               owns the Company or all or substantially all of the Company's
               assets either directly or through one or more subsidiaries) in
               substantially the same proportions as their ownership,
               immediately prior to such Business Combination of the Outstanding
               Company Common Stock and Outstanding Company Voting Securities,
               as the case may be, (B) no Person (excluding any corporation
               resulting from such Business Combination or any employee benefit
               plan (or related trust) of the Company or such corporation
               resulting from such Business Combination and any Person
               beneficially owning, immediately prior to such Business
               Combination, directly or indirectly, 20% or more of the
               Outstanding Common Stock or Outstanding Voting Securities, as the
               case may be) beneficially owns, directly or indirectly, twenty
               percent (20%) or more of, respectively, the then outstanding
               shares of common stock of the corporation resulting from such
               Business Combination, or the combined voting power of the then
               outstanding voting securities of such corporation entitled to
               vote generally in the election of directors and (C) at least a
               majority of the members of the board of directors of the
               corporation resulting from such Business Combination were members
               of the Incumbent Board at the time of 

                                       3
<PAGE>
 
               the execution of the initial agreement, or of the action of the
               Board, providing for such Business Combination; or

          4.   Approval by the shareholders of the Company of a complete
               liquidation or dissolution of the Company other than to a
               corporation which would satisfy the requirements of clauses (A),
               (B) and (C) of Subsection (3) of this Section 1(e), assuming for
               this purpose that such liquidation or dissolution was a Business
               Combination.

     f.  Good Cause:  The determination by board of directors of the Company, in
good faith and in the exercise of its reasonable judgment, that Executive has
committed an act or acts which constitute (i) a felony which reasonably could be
expected to have a material adverse impact on the Company or the ability of
Executive to perform his duties to the Company in connection with his
employment, (ii) dishonesty or fraud with respect to the Company having a
material adverse impact on the Company, excluding for this purpose an isolated
and inadvertent action not taken in bad faith by Executive and which Executive
promptly takes reasonable actions to remedy after the board of directors has
delivered written notice thereof to Executive, or (iii) willfully engaging in
one or more acts, or willfully omitting to act, which is demonstrably and
materially damaging to the Company or any of its subsidiaries.  For purposes of
this Agreement, an act or failure to act on Executive's part shall be considered
"willful" only if it was done or omitted to be done by him not in good faith,
and shall not include any act or failure to act resulting from any incapacity of
Executive.  Notwithstanding the foregoing, Executive may not be terminated for
Good Cause unless and until (1) the Executive shall have committed acts which
constitute Good Cause as set forth in this Section 1(f), and (2) there shall
have been delivered to him a copy of a resolution duly adopted by a seventy-five
percent (75%) affirmative vote of the membership of the Board of Directors of
the Company (the "Board") (excluding Executive, if he is then a member) at a
meeting of the Board called and held for such purpose (after giving Executive
reasonable notice specifying the nature of the grounds for such termination and
not less than 30 days to correct the acts or omissions complained of, if
correctable, and affording Executive the opportunity, together with his counsel,
to be heard before  the Board) finding that Executive was guilty of conduct
which constitutes Good Cause as set forth in this Section 1(f).

     g.  Good Reason:   The occurrence of any of the following:  (i) the
assignment to Executive of duties materially inconsistent with the status of
Executive's position with the Company or the diminution in the nature or status
of Executive's duties and powers and Executive's responsibilities in connection
with such duties and powers excluding for this purpose an isolated,
insubstantial and inadvertent action not taken in bad faith and which is
remedied by the Company promptly after receipt of notice thereof given by the
Executive; (ii) a requirement by the Company that Executive relocate his primary
residence outside of the area comprising a 50 mile radius around the then
current location of such residence (the "Area"); (iii) any requirement for
Executive to spend on a regular basis a greater number of days per month or a
greater number of consecutive days away from the Area, excluding any days of
travel initiated by Executive or travel agreed to by the Company and Executive
and provided that Executive agrees to travel consistent with past practice

                                       4
<PAGE>
 
and as reasonably required to perform the responsibilities of his position
consistent with past practice; (iv) the reduction of Executive's base salary;
(v) a change in the composition of the plan pursuant to which Executive is
eligible for incentive compensation such that Executive's ability to earn such
incentive compensation is significantly diminished; or (vi) reduction in the
benefits provided or made available by the Company to Executive or the portion
of the cost of such benefits borne by the Company, other than modifications of
benefits under general benefit plans which are available to substantially all
full time employees.

          For purposes of this Section, any good faith determination of "Good
Reason" made by the Executive shall be conclusive.

2.   Termination of Employment; Severance Pay.  If Executive's employment with
the Company is terminated by Executive for Good Reason or by the Company, other
than for Good Cause, then the Company shall:

     a.  pay to Executive, during the applicable Payout Period, the Aggregate
Severance Pay as follows:

          (i) if such termination occurs at any time during the period beginning
     on the [60th] day preceding the occurrence of a Change in Control and
     ending on the first anniversary of the occurrence of such Change in Control
     (the "Initial Period"), then the applicable Payout Period shall be 36
     months; or

          (ii) if such termination occurs at any time during the period
     beginning immediately following the expiration of the Initial Period and
     ending on the second anniversary of such Change in Control (the "Extended
     Period"), then the applicable Payout Period shall be 24 months; and

     b.  if such termination occurs during the Initial Period, pay the Bonus
Amount to Executive in a lump sum in cash within 30 days after the date of
Executive's termination of employment; and

     c.  if such termination occurs during the Initial Period or the Extended
Period, during the one year period following termination of Executive's
employment with the Company or its affiliated companies the Executive and/or the
Executive's family, as the case may be, shall be eligible for participation in
and shall receive all benefits under welfare benefit plans, practices, policies
and programs provided by the Company and its affiliated companies (including,
without limitation, medical, prescription, dental, disability, salary
continuance, employee life, group life, accidental death and travel accident
insurance plans and programs) to the extent applicable generally to other peer
executives of the Company and its affiliated companies, but in no event shall
such plans, practices, policies and programs provide the Executive with benefits
which are less favorable, in the aggregate, than the most favorable of such
plans, practices, policies and programs in effect for the 

                                       5
<PAGE>
 
Executive at any time during the 90-day period immediately preceding the
occurrence of the Change in Control or, if more favorable to the Executive,
those provided generally at any time after the occurrence of the Change in
Control to other peer executives of the Company and its affiliated companies.

     The Aggregate Severance Pay shall be payable, at the Severance Pay Rate, in
accordance with the Company's or its successor's standard payroll practices
during the applicable Payout Period.  In lieu of regular payments of the
Aggregate Severance Pay during the Payout Period, Executive shall be entitled to
receive, upon Executive's written election delivered within 10 business days
following the termination of Executive's employment with the Company, a lump sum
payment equal to the present value of the stream of monthly payments of the
Aggregate Severance Pay during the Payout Period, for purposes of which each
monthly payment shall be equal to the Severance Pay Rate divided by twelve.  For
purposes of this computation, present value shall be determined in accordance
with Internal Revenue Code (the "Code") Section 280G, using a discount rate
equal to 120% of the applicable Federal Rate (determined under Section 1274(d)
of the Code), compounded semi-annually, determined as of the date of Executive's
election to receive the lump sum payment provided for herein.

3.   Gross Up for Excise Tax Liability. If it shall be determined that any
payment received or to be received by Executive under this Agreement or any
other agreement, plan or program which provides for additional compensation to
be paid to the Executive upon the occurrence of a Change in Control (a
"Payment"), would be subject to the excise tax imposed by Section 4999 of the
Internal revenue Code of 1986, as amended (the "Excise Tax"), then the Company
shall pay to Executive an additional payment (a "Gross-Up Payment") in an amount
necessary to reimburse Executive, on an after-tax basis, for the Excise Tax and
for any federal, state and local income tax and excise tax (including any
interest and penalties imposed with respect to such taxes) that may be imposed
by reason of the Payment.  For purposes of determining the amount of any Gross-
Up Payment, Executive shall be deemed to pay federal, state and local income
taxes at the highest applicable marginal rate of taxation in the calendar year
in which such Gross-Up Payment is to be made.  All determinations required to be
made under this Section 3, including whether a Gross-Up Payment is required and
the amount of such Gross-Up Payment shall be made by the firm of independent
certified public accountants then retained by the Company (the "Accounting
Firm") which shall provide, in writing, detailed supporting calculations both to
the Company and Executive within 15 business days of the request for such
determination.  Such request may be made by either party.  The Company shall pay
the fees and expenses of the Accounting Firm in connection with any
determinations hereunder.  The Gross-Up Payment shall be paid by the Company
within 10 days of the Accounting Firm's determination of the amount thereof.

     In the event that the Excise Tax is determined to exceed the amount taken
into account hereunder at the time the Gross-up Payment is made, including by
reason of any payment the existence or amount of which cannot be determined at
the time of the Gross-up Payment, the Company shall make an additional Gross-up
Payment in respect of such excess (plus any interest and penalties payable with
respect to such excess) at the time that the amount of such excess is 

                                       6
<PAGE>
 
finally determined.

     In the event that the Excise Tax is subsequently determined to be less than
the amount determined by the Accounting Firm, the Executive shall repay to the
Company at the time that the amount of such reduction in Excise Tax is finally
refunded to or otherwise realized as a benefit by Executive, the portion of the
Gross-up Payment that would not have been paid, plus interest on the amount of
such repayment at the rate provided in Section 1274(b)(2)(B) of the Code.

     The Executive shall notify the Company in writing of any claim by the
Internal Revenue Service that would require payment by the Company of the Gross-
Up Payment.  If the Company elects to contest such claim, the Executive shall:

               (i)    give the Company any information reasonably requested by
                      the Company relating to such claim,

               (ii)   take such action to contest such claim as the Company (or
                      its counsel) shall reasonably request, and

               (iii)  cooperate with the Company in good faith in order to
                      effectively contest such claim.

The Company shall bear and pay directly all costs and expenses (including
additional interest and penalties) incurred in connection with such contest and
shall indemnify and hold the Executive harmless, on an after-tax basis, for any
Excise Tax or income tax (including interest and penalties with respect thereto)
imposed as a result of such contest, and the Executive agrees to prosecute such
contest to a determination as the Company shall determine; provided, however,
the Company shall advance the amount of any payment pending the contest to the
Executive and shall indemnify the Executive with respect to any taxes (including
penalties and interest, if any) which may be imposed in connection with the
advance of such funds.

4.   No Duty to Mitigate.  The Executive shall not be required or have any duty
or obligation to mitigate the amount of any payment provided for under this
Agreement by seeking other employment or otherwise.  In addition, no payment to
be provided to Executive pursuant to this Agreement shall be reduced by any
compensation or other amount earned or collected by Executive at any time before
or after the termination of Executive's employment with the Company.

5.   Cooperation.

                                       7
<PAGE>
 
     a.  Executive agrees to cooperate with the Company (including following
Executive's termination of employment for any reason), provided that such
cooperation would not unreasonably interfere with the business activities or
employment obligations of the Executive, by making himself available to testify
on behalf of the Company or any subsidiary or affiliate of the Company, in any
action, suit, or proceeding, whether civil, criminal, administrative, or
investigative, and to assist the Company, or any subsidiary or affiliate of the
Company, in any such action, suit, or proceeding, by providing information and
meeting and consulting with the Board and its representatives or counsel, or
representatives or counsel of or to the Company, or any subsidiary or affiliate
of the Company, as requested; provided, however, this subsection (a) shall not
apply to any action between the Executive and the Company to enforce this
Agreement.  The Company agrees to reimburse Executive, on an after-tax basis,
for all expenses actually incurred in connection with his provision of testimony
or assistance.

     b.  Executive agrees, as a condition to receipt of the termination payments
and benefits provided hereunder, that he will execute a release agreement, in a
form satisfactory to the Company, releasing any and all claims arising out of
Executive's employment (other than claims made pursuant to any indemnities
provided under the articles or by-laws of the Company, under any directors or
officers liability insurance policies maintained by the Company, under any
employee benefit plans or executive compensation plans of the Company, or
enforcement of this Agreement).

6.   Intellectual Property Rights.

     a.  Executive agrees that the Company will be the sole owner of any and all
of Executive's "Discoveries" and "Work Product" made during the term of his
employment with the Company.  For these purposes "Discoveries" means all
inventions, discoveries, improvements, and copyrightable works (including,
without limitation, any information relating to the Company's software products,
source code, know-how, processes, designs, algorithms, computer programs and
routines, formulae, techniques, developments or experimental work, work-in-
progress, or business trade secrets) made or conceived or reduced to practice by
Executive, whether or not potentially patentable or copyrightable in the United
States or elsewhere.  For purposes of this Agreement, "Work Product" means any
and all work product relating to Discoveries.

     b.  Executive shall promptly disclose to the Company all Discoveries and
Work Product.  All such disclosures must include complete and accurate copies of
all source code, object code or machine-readable copies, documentation, work
notes, flow-charts, diagrams, test data, reports, samples, and other tangible
evidence or results (collectively, "Tangible Embodiments") of such Discoveries
or Work Product.  All Tangible Embodiments of any Discoveries or Work Product
will be deemed to have been assigned to the Company as a result of the act of
expressing any Discovery or Work Product therein.

     c.  Executive hereby assigns and agrees to assign to the Company all of his
interest in any country in any and all Discoveries and Work Product, whether
such interest arises under patent law, copyright law, trade-secret law,
semiconductor chip protection law, or otherwise.  Without 

                                       8
<PAGE>
 
limiting the generality of the preceding sentence, Executive hereby authorizes
the Company to make any desired changes to any part of any Discovery or Work
Product, to combine it with other materials in any manner desired, and to
withhold Executive's identity in connection with any distribution or use thereof
alone or in combination with other materials. This assignment and assignment
obligation applies to all Discoveries and Work Product arising during
Executive's employment with the Company (or its predecessors), whether pursuant
to this Agreement or otherwise.

     d.  At the request of the Company, Executive shall promptly and without
additional compensation execute any and all patent applications, copyright
registration applications, waivers of moral rights, assignments, or other
instruments that the Company deems necessary or appropriate to apply for or
obtain Letters Patent of the United States or any foreign country, copyright
registrations or otherwise to protect the Company's interest in such Discovery
and Work Product, the expenses for which will be borne by the Company.
Executive hereby irrevocably designates and appoints the Company and its duly
authorized officers and agents as his agents and attorneys-in-fact to, if the
Company is unable for any reason to secure Executive's signature to any lawful
and necessary document required or appropriate to apply for or execute any
patent application, copyright registration application, waiver of moral rights,
or other similar document with respect to any Discovery and Work Product
(including, without limitation, renewals, extensions, continuations, divisions,
or continuations in part), (I) act for and in his behalf, (ii) execute and file
any such document, and (iii) do all other lawfully permitted acts to further the
prosecution of the same legal force and effect as if executed by him; this
designation and appointment constitutes an irrevocable power of attorney coupled
with an interest.

     e.  To the extent that any Discovery or Work Product constitutes
copyrightable or similar subject matter that is eligible to be treated as a
"work made for hire" or as having similar status in the United States or
elsewhere, it will be so deemed.  This provision does not alter or limit
Executive's other obligations to assign intellectual property rights as provided
above.

     f.  The obligations of Executive set forth in this Section 6 (including,
without limitation, the assignment obligations) will survive and continue
beyond the termination of Executive's employment and termination of this
Agreement with respect to Discoveries and Work Product conceived or made by
Executive alone or in concert with others during Executive's employment with the
Company.  Those obligations will be binding upon Executive, his executors,
administrators, and other representatives.

7.   Exposure to Proprietary Information.

     a.  As used in this Agreement, "Proprietary Information" means all
information of a business or technical nature that relates to the Company
including, without limitation, all information about software products whether
currently released or in development, all inventions, discoveries, improvements,
copyrightable work, source code, know-how, processes, designs, algorithms,
computer programs and routines, formulae and techniques, and any information
regarding the business of any customer or supplier of the Company or any other
information that the Company is 

                                       9
<PAGE>
 
required to keep confidential. Notwithstanding the preceding sentence, the term
"Proprietary Information" does not include information that is or becomes
publicly available through no fault of Executive.

     b.  Executive acknowledges that the Proprietary Information constitutes a
protectible business interest of the Company, and covenants and agrees that
during and after the term of his employment by the Company or, he will not,
directly or indirectly, disclose, furnish, make available or utilize any of the
Proprietary Information, other than in the proper performance of his duties for
the Company.  Executive's obligations under this Section 7 with respect to
particular Proprietary Information will survive expiration or termination of
this Agreement and Executive's employment with the Company, and will terminate
only at such time (if any) as the Proprietary Information in question becomes
generally known to the public other than through a breach of Executive's
obligations under this Section 7.

     c.  Executive acknowledges that all records, documents, and Tangible
Embodiments containing or of Proprietary Information prepared by Executive or
coming into his possession by virtue of his employment by the Company are and
will remain the property of the Company.  Upon termination of his employment
with the Company, Executive shall immediately return to the Company all such
items in his possession and all copies of such items.

8.   Equitable Remedies.

     a.  Executive acknowledges and agrees that the agreements and covenants set
forth in Sections 6, 7, and 8 are reasonable and necessary for the protection of
the Company's business interests, that irreparable injury will result to the
Company if Executive breaches any of the terms of said covenants, and that in
the event of Executive's actual or threatened breach of any such covenants, the
Company will have no adequate remedy at law.  Executive accordingly agrees that,
in the event of any actual or threatened breach by him of any of said covenants,
the Company will be entitled to immediate injunctive and other equitable relief,
without bond and without the necessity of showing actual monetary damages.
Nothing in this Section 8 will be construed as prohibiting the Company from
pursuing any other remedies available to it for such breach or threatened
breach, including the recovery of any damages that it is able to prove.

     b.  Each of the covenants in Sections 6, 7, and 8 will be construed as
independent of any other covenants or other provisions of this Agreement.

     c.  In the event of any judicial determination that any of the covenants in
Sections 6, 7, and 8 are not fully enforceable, it is the intention and desire
of the parties that the court treat said covenants as having been modified to
the extent deemed necessary by the court to render them reasonable and
enforceable, and that the court enforce them to such extent.

9.   Termination.  The Company may terminate this Agreement at any time, for any
reason or no reason by written notice to Executive, provided that a Change in
Control has not yet occurred at the 

                                       10
<PAGE>
 
time such notice is given and does not occur within 90 days after the notice of
termination has been given by the Company to Executive, and in such cases such
purported termination shall be of no effect and this Agreement shall continue
and may not be terminated by the Company.

10.  Miscellaneous.  Any notice or other communication required or permitted
hereunder shall be in writing and shall be deemed to have been properly given
(a) if sent by United States mail, certified or registered, (b) if sent prepaid
by overnight courier, or (c) when delivered in person to the following

     d.  Counterparts.  This Agreement may be executed simultaneously in one or
more 

                                       11
<PAGE>
 
counterparts, each of which shall be deemed an original but all of which
together shall constitute one and the same instrument.

     e.  Entire Agreement.  Subject to the rights, benefits and obligations
provided for under any executive compensation and employee benefit plans of the
Company, this Agreement represents the entire agreement and understanding of the
parties hereto with respect to the matters set forth herein. This Agreement

waived, only by a written instrument signed by the parties hereto or, in the
case of a waiver, by the party waiving compliance.

     f.  Waivers.  No delay on the part of any party in exercising any right,
power or privilege hereunder shall operate as a waiver thereof.  Nor shall any
waiver on the part of any party of any such right, power or privilege hereunder,

preclude any other or further exercise thereof or the exercise of any other
right, power or privilege hereunder.

     g.  Headings.  The headings in this Agreement are inserted for convenience
only and are not to be considered in the interpretation or construction of the
provisions hereof.

     h.  Arbitration.  Except for any claim or dispute which gives rise or could
give rise to equitable relief under this Agreement, at the request of the
Executive any disagreement, dispute, controversy or claim arising out of or
relating to this Agreement or the breach hereof shall be settled exclusively and
finally by binding arbitration.  The arbitration shall be conducted in
accordance with the Commercial Arbitration Rules of the American Arbitration
Association (hereinafter referred to as "AAA Rules").  Such arbitration shall be
conducted in Chicago, Illinois, or in such other city as the parties to the
dispute may designate by mutual consent.  The arbitral tribunal shall consist of
three arbitrators (or such lesser number as may be agreed upon by the parties)
selected according to the procedure set forth in the AAA Rules in effect on the
date hereof and the arbitrators shall be empowered to order any remedy which is
appropriate to the proceedings and issues presented to them.  The chairman of
the arbitral tribunal shall be appointed by the American Arbitration Association
from among the three arbitrators so selected.  Any party to a decision rendered
in such arbitration proceedings may seek an order enforcing the same by any
court having jurisdiction.

     i.  No Strict Construction.  The language used in this Agreement will be
deemed to be the language chosen by Executive and the Company to express their
mutual intent, and no rule of strict construction will be applied against
Executive or the Company.

     j.  Legal Expenses. Executive shall be entitled to recover any expenses for
attorney's fees and disbursements incurred by him in connection with enforcing
his rights under this Agreement whether or not Executive is successful in
asserting such rights; provided, however, that no

                                       12
<PAGE>
 
reimbursement shall be made of such expenses relating to any unsuccessful
assertion of rights if and to the extent that Executive's assertion of such
rights was in bad faith or frivolous, as determined by independent counsel
mutually acceptable to Executive and the Company and made without reference to
or not related to a Change in Control. Amounts payable to Executive hereunder
which are not paid when due to be paid shall bear interest from their due date
at the prime rate of interest published from time to time in the Midwest edition
of the Wall Street Journal plus two percent (2%).

     k.  Non-Transferability.  Neither this Agreement nor the rights or
obligations hereunder of the parties hereto shall be transferable or assignable
by Executive, except in accordance with the laws of descent and distribution.

hereunder, and shall assign this Agreement, to any Successor (as hereinafter
defined) which, by operation of law or otherwise, continues to carry on
substantially the business of the Company prior to the event of succession, and
the Company shall, as a condition of the succession, require such Successor to
agree to assume the  Company's obligations and be bound by this Agreement.  For
purposes of this Agreement, "Successor" shall mean any person that succeeds to,
or has the practical ability to control (either immediately or with the passage
of time), the Company's business directly, by merger or consolidation, or
indirectly, by purchase of the Company's voting securities or all or
substantially all of its assets, or otherwise.

     l.  No Offsets.  The amounts required to be paid by the Company to
Executive pursuant to this Agreement shall not be subject to offset,
counterclaim, recoupment, defense or other claim, right or action which the
Company may have against Executive or others, other than with respect to any
amounts that are owed to the Company by Executive due to his receipt of Company
funds as a result of his fraudulent activity.  The foregoing and other
provisions of this Agreement notwithstanding, all payments to be made to
Executive under this Agreement will be subject to required withholding taxes and
other required deductions.

     IN WITNESS WHEREOF, the Company and Executive have signed or caused a duly
authorized representative to sign this Agreement as of the day and year written
above.

                    PLATINUM technology International, inc.
                            SEVERANCE PAY AGREEMENT
                            -----------------------



     This Severance Pay Agreement ( this "Agreement") is made and entered into
as of the 31st day of August, 1998 by and between PLATINUM technology, inc., a
Delaware corporation (together with its subsidiaries, the "Company"), and Paul
A. Tatro (the "Executive").

                                   WITNESSETH
                                   ----------

     WHEREAS, Executive has certain unique expertise, skills, contacts and
experience relating to the Company's business;

     WHEREAS, Executive is currently employed by the Company and the Company
believes that the continuation of such employment is material to the continued
success of the Company;

     WHEREAS, in light of the fact that the Company is publicly-held, the
Company recognizes and acknowledges that it is necessary, to retain Executive,
to provide certain security to Executive in the event that a Change in Control
(as defined below) of the Company should occur; and

     WHEREAS, to that end, the Company desires to provide for severance pay to
Executive in the event that Executive's employment with the Company is
terminated in connection with or as a result of a Change in Control, on the
terms and conditions set forth herein.

     NOW, THEREFORE, in consideration of the mutual covenants and agreements
contained herein, and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereby agree as
follows:

1.   Certain Definitions.  As used in this Agreement the following initially
capitalized terms shall have the following meanings:

     a.  Severance Pay Rate:  The annual rate of compensation payable by the
Company to Executive as severance pay, which shall be equal to the sum of the
greatest amount of each of (i) the base salary plus (ii) the incentive
compensation, respectively, paid to Executive during any trailing 12 month
period or periods (it being expressly understood that the 12 month periods
utilized to determine base salary and incentive compensation may be different)
during the 36 month period preceding termination of Executive's employment with
the Company; provided, however, if Executive's annual base salary rate at the
time of termination is greater than his base salary in the greatest trailing 12
month period, then such annual base salary rate shall be utilized for purposes

     e.  Change in Control:  The first to occur of the following:

         1.    The acquisition by any individual, entity or group (within the
               meaning of Section 13(d)(3) or 14(d)(2) of the Securities
               Exchange Act of 1934, as amended (the "Exchange Act")) (a
               "Person") of beneficial ownership (within the meaning of Rule
               13d-3 promulgated under the Exchange Act) of twenty percent (20%)
               or more of either (A) the then-outstanding shares of common stock
               of the Company (the "Outstanding Company Common Stock") or (B)
               the combined voting power of the then-outstanding voting
               securities of the Company entitled to vote generally in the
               election of directors (the "Outstanding Company Voting
               Securities"); provided, however, that for purposes of this
               subsection (i), the following acquisitions shall not constitute a
               Change in Control: (A) any acquisition directly from the Company
               other than in connection with the acquisition by the Company or
               its affiliates of a business, (B) any acquisition by the Company,
               (C) any acquisition by any employee benefit plan (or related

               Company pursuant to a debt restructuring of the Company, or (E)
               any acquisition by any corporation pursuant to a transaction

               this Section 1(e);

                                       2
<PAGE>
 
          2.   Individuals who, as of the date hereof, constitute the Board (the
               "Incumbent Board") cease for any reason to constitute at least a
               majority of the Board; provided, however, that any individual
               becoming a director subsequent to the date hereof whose election,
               or nomination for election by the Company's shareholders, was
               approved by a vote of at least a majority of the directors then
               comprising the Incumbent Board shall be considered as though such
               individual were a member of the Incumbent Board, but excluding,
               for this purpose, any such individual whose initial assumption of
               office occurs as a result of an actual or threatened election
               contest with respect to the election or removal of directors or
               other actual or threatened solicitation of proxies or consents by
               or on behalf of a Person other than the Board;

          3.   Consummation of a reorganization, merger or consolidation of the
               Company or any direct or indirect subsidiary of the Company or
               sale or other disposition of all or substantially all of the
               assets of the Company (a "Business Combination"), in each case,
               unless, following such Business Combination, (A) all or
               substantially all of the individuals and entities who were the
               beneficial owners, respectively, of the Outstanding Company
               Common Stock and Outstanding Company Voting Securities
               immediately prior to such Business Combination beneficially own,
               directly or indirectly, more than sixty percent (60%) of,
               respectively, the then-outstanding shares of common stock and the
               combined voting power of the then outstanding voting securities
               entitled to vote generally in the election of directors, as the
               case may be, of the corporation resulting from such Business
               Combination (which shall include for these purposes, without
               limitation, a corporation which as a result of such transaction
               owns the Company or all or substantially all of the Company's
               assets either directly or through one or more subsidiaries) in
               substantially the same proportions as their ownership,
               immediately prior to such Business Combination of the Outstanding
               Company Common Stock and Outstanding Company Voting Securities,
               as the case may be, (B) no Person (excluding any corporation
               resulting from such Business Combination or any employee benefit
               plan (or related trust) of the Company or such corporation
               resulting from such Business Combination and any Person
               beneficially owning, immediately prior to such Business
               Combination, directly or indirectly, 20% or more of the
               Outstanding Common Stock or Outstanding Voting Securities, as the
               case may be) beneficially owns, directly or indirectly, twenty
               percent (20%) or more of, respectively, the then outstanding
               shares of common stock of the corporation resulting from such
               Business Combination, or the combined voting power of the then
               outstanding voting securities of such corporation entitled to
               vote generally in the election of directors and (C) at least a
               majority of the members of the board of directors of the
               corporation resulting from such Business Combination were members
               of the Incumbent Board at the time of 

                                       3
<PAGE>
 
               the execution of the initial agreement, or of the action of the
               Board, providing for such Business Combination; or

          4.   Approval by the shareholders of the Company of a complete
               liquidation or dissolution of the Company other than to a
               corporation which would satisfy the requirements of clauses (A),
               (B) and (C) of Subsection (3) of this Section 1(e), assuming for
               this purpose that such liquidation or dissolution was a Business
               Combination.



     f.  Good Cause:  The determination by board of directors of the Company, in
good faith and in the exercise of its reasonable judgment, that Executive has
committed an act or acts which constitute (i) a felony which reasonably could be
expected to have a material adverse impact on the Company or the ability of
Executive to perform his duties to the Company in connection with his
employment, (ii) dishonesty or fraud with respect to the Company having a
material adverse impact on the Company, excluding for this purpose an isolated
and inadvertent action not taken in bad faith by Executive and which Executive
promptly takes reasonable actions to remedy after the board of directors has
delivered written notice thereof to Executive, or (iii) willfully engaging in
one or more acts, or willfully omitting to act, which is demonstrably and
materially damaging to the Company or any of its subsidiaries.  For purposes of
this Agreement, an act or failure to act on Executive's part shall be considered
"willful" only if it was done or omitted to be done by him not in good faith,
and shall not include any act or failure to act resulting from any incapacity of
Executive.  Notwithstanding the foregoing, Executive may not be terminated for
Good Cause unless and until (1) the Executive shall have committed acts which
constitute Good Cause as set forth in this Section 1(f), and (2) there shall
have been delivered to him a copy of a resolution duly adopted by a seventy-five
percent (75%) affirmative vote of the membership of the Board of Directors of
the Company (the "Board") (excluding Executive, if he is then a member) at a
meeting of the Board called and held for such purpose (after giving Executive
reasonable notice specifying the nature of the grounds for such termination and
not less than 30 days to correct the acts or omissions complained of, if
correctable, and affording Executive the opportunity, together with his counsel,
to be heard before  the Board) finding that Executive was guilty of conduct
which constitutes Good Cause as set forth in this Section 1(f).



     g.  Good Reason:   The occurrence of any of the following:  (i) the
assignment to Executive of duties materially inconsistent with the status of
Executive's position with the Company or the diminution in the nature or status
of Executive's duties and powers and Executive's responsibilities in connection
with such duties and powers excluding for this purpose an isolated,
insubstantial and inadvertent action not taken in bad faith and which is
remedied by the Company promptly after receipt of notice thereof given by the
Executive; (ii) a requirement by the Company that Executive relocate his primary
residence outside of the area comprising a 50 mile radius around the then
current location of such residence (the "Area"); (iii) any requirement for
Executive to spend on a regular basis a greater number of days per month or a
greater number of consecutive days away from the Area, excluding any days of
travel initiated by Executive or travel agreed to by the Company and Executive
and provided that Executive agrees to travel consistent with past practice

                                       4
<PAGE>
 
and as reasonably required to perform the responsibilities of his position
consistent with past practice; (iv) the reduction of Executive's base salary;
(v) a change in the composition of the plan pursuant to which Executive is
eligible for incentive compensation such that Executive's ability to earn such
incentive compensation is significantly diminished; or (vi) reduction in the
benefits provided or made available by the Company to Executive or the portion
of the cost of such benefits borne by the Company, other than modifications of
benefits under general benefit plans which are available to substantially all
full time employees.

          For purposes of this Section, any good faith determination of "Good
Reason" made by the Executive shall be conclusive.

2.   Termination of Employment; Severance Pay.  If Executive's employment with
the Company is terminated by Executive for Good Reason or by the Company, other
than for Good Cause, then the Company shall:

     a.  pay to Executive, during the applicable Payout Period, the Aggregate
Severance Pay as follows:

          (i) if such termination occurs at any time during the period beginning
     on the [60th] day preceding the occurrence of a Change in Control and
     ending on the first anniversary of the occurrence of such Change in Control
     (the "Initial Period"), then the applicable Payout Period shall be 36
     months; or

          (ii) if such termination occurs at any time during the period
     beginning immediately following the expiration of the Initial Period and
     ending on the second anniversary of such Change in Control (the "Extended
     Period"), then the applicable Payout Period shall be 24 months; and



     b.  if such termination occurs during the Initial Period, pay the Bonus
Amount to Executive in a lump sum in cash within 30 days after the date of
Executive's termination of employment; and



     c.  if such termination occurs during the Initial Period or the Extended
Period, during the one year period following termination of Executive's
employment with the Company or its affiliated companies the Executive and/or the
Executive's family, as the case may be, shall be eligible for participation in
and shall receive all benefits under welfare benefit plans, practices, policies
and programs provided by the Company and its affiliated companies (including,
without limitation, medical, prescription, dental, disability, salary
continuance, employee life, group life, accidental death and travel accident
insurance plans and programs) to the extent applicable generally to other peer
executives of the Company and its affiliated companies, but in no event shall
such plans, practices, policies and programs provide the Executive with benefits
which are less favorable, in the aggregate, than the most favorable of such
plans, practices, policies and programs in effect for the 

                                       5
<PAGE>
 
Executive at any time during the 90-day period immediately preceding the
occurrence of the Change in Control or, if more favorable to the Executive,
those provided generally at any time after the occurrence of the Change in
Control to other peer executives of the Company and its affiliated companies.

     The Aggregate Severance Pay shall be payable, at the Severance Pay Rate, in
accordance with the Company's or its successor's standard payroll practices
during the applicable Payout Period.  In lieu of regular payments of the
Aggregate Severance Pay during the Payout Period, Executive shall be entitled to
receive, upon Executive's written election delivered within 10 business days
following the termination of Executive's employment with the Company, a lump sum
payment equal to the present value of the stream of monthly payments of the
Aggregate Severance Pay during the Payout Period, for purposes of which each
monthly payment shall be equal to the Severance Pay Rate divided by twelve.  For
purposes of this computation, present value shall be determined in accordance
with Internal Revenue Code (the "Code") Section 280G, using a discount rate
equal to 120% of the applicable Federal Rate (determined under Section 1274(d)
of the Code), compounded semi-annually, determined as of the date of Executive's
election to receive the lump sum payment provided for herein.

3.   Gross Up for Excise Tax Liability. If it shall be determined that any
payment received or to be received by Executive under this Agreement or any
other agreement, plan or program which provides for additional compensation to
be paid to the Executive upon the occurrence of a Change in Control (a
"Payment"), would be subject to the excise tax imposed by Section 4999 of the
Internal revenue Code of 1986, as amended (the "Excise Tax"), then the Company
shall pay to Executive an additional payment (a "Gross-Up Payment") in an amount
necessary to reimburse Executive, on an after-tax basis, for the Excise Tax and
for any federal, state and local income tax and excise tax (including any
interest and penalties imposed with respect to such taxes) that may be imposed
by reason of the Payment.  For purposes of determining the amount of any Gross-
Up Payment, Executive shall be deemed to pay federal, state and local income
taxes at the highest applicable marginal rate of taxation in the calendar year
in which such Gross-Up Payment is to be made.  All determinations required to be
made under this Section 3, including whether a Gross-Up Payment is required and
the amount of such Gross-Up Payment shall be made by the firm of independent
certified public accountants then retained by the Company (the "Accounting
Firm") which shall provide, in writing, detailed supporting calculations both to
the Company and Executive within 15 business days of the request for such
determination.  Such request may be made by either party.  The Company shall pay
the fees and expenses of the Accounting Firm in connection with any
determinations hereunder.  The Gross-Up Payment shall be paid by the Company
within 10 days of the Accounting Firm's determination of the amount thereof.

     In the event that the Excise Tax is determined to exceed the amount taken
into account hereunder at the time the Gross-up Payment is made, including by
reason of any payment the existence or amount of which cannot be determined at
the time of the Gross-up Payment, the Company shall make an additional Gross-up
Payment in respect of such excess (plus any interest and penalties payable with
respect to such excess) at the time that the amount of such excess is 

                                       6
<PAGE>
 
finally determined.

     In the event that the Excise Tax is subsequently determined to be less than
the amount determined by the Accounting Firm, the Executive shall repay to the
Company at the time that the amount of such reduction in Excise Tax is finally
refunded to or otherwise realized as a benefit by Executive, the portion of the
Gross-up Payment that would not have been paid, plus interest on the amount of
such repayment at the rate provided in Section 1274(b)(2)(B) of the Code.

     The Executive shall notify the Company in writing of any claim by the
Internal Revenue Service that would require payment by the Company of the Gross-
Up Payment.  If the Company elects to contest such claim, the Executive shall:

               (i)    give the Company any information reasonably requested by
                      the Company relating to such claim,

               (ii)   take such action to contest such claim as the Company (or
                      its counsel) shall reasonably request, and

               (iii)  cooperate with the Company in good faith in order to
                      effectively contest such claim.


The Company shall bear and pay directly all costs and expenses (including
additional interest and penalties) incurred in connection with such contest and
shall indemnify and hold the Executive harmless, on an after-tax basis, for any
Excise Tax or income tax (including interest and penalties with respect thereto)
imposed as a result of such contest, and the Executive agrees to prosecute such
contest to a determination as the Company shall determine; provided, however,
the Company shall advance the amount of any payment pending the contest to the
Executive and shall indemnify the Executive with respect to any taxes (including
penalties and interest, if any) which may be imposed in connection with the
advance of such funds.

4.   No Duty to Mitigate.  The Executive shall not be required or have any duty
or obligation to mitigate the amount of any payment provided for under this
Agreement by seeking other employment or otherwise.  In addition, no payment to
be provided to Executive pursuant to this Agreement shall be reduced by any
compensation or other amount earned or collected by Executive at any time before
or after the termination of Executive's employment with the Company.


5.   Cooperation.

                                       7
<PAGE>
 
     a.  Executive agrees to cooperate with the Company (including following
Executive's termination of employment for any reason), provided that such
cooperation would not unreasonably interfere with the business activities or
employment obligations of the Executive, by making himself available to testify
on behalf of the Company or any subsidiary or affiliate of the Company, in any
action, suit, or proceeding, whether civil, criminal, administrative, or
investigative, and to assist the Company, or any subsidiary or affiliate of the
Company, in any such action, suit, or proceeding, by providing information and
meeting and consulting with the Board and its representatives or counsel, or
representatives or counsel of or to the Company, or any subsidiary or affiliate
of the Company, as requested; provided, however, this subsection (a) shall not
apply to any action between the Executive and the Company to enforce this
Agreement.  The Company agrees to reimburse Executive, on an after-tax basis,
for all expenses actually incurred in connection with his provision of testimony
or assistance.

     b.  Executive agrees, as a condition to receipt of the termination payments
and benefits provided hereunder, that he will execute a release agreement, in a
form satisfactory to the Company, releasing any and all claims arising out of
Executive's employment (other than claims made pursuant to any indemnities
provided under the articles or by-laws of the Company, under any directors or
officers liability insurance policies maintained by the Company, under any
employee benefit plans or executive compensation plans of the Company, or
enforcement of this Agreement).

6.   Intellectual Property Rights.

     a.  Executive agrees that the Company will be the sole owner of any and all
of Executive's "Discoveries" and "Work Product" made during the term of his
employment with the Company.  For these purposes "Discoveries" means all
inventions, discoveries, improvements, and copyrightable works (including,
without limitation, any information relating to the Company's software products,
source code, know-how, processes, designs, algorithms, computer programs and
routines, formulae, techniques, developments or experimental work, work-in-
progress, or business trade secrets) made or conceived or reduced to practice by
Executive, whether or not potentially patentable or copyrightable in the United
States or elsewhere.  For purposes of this Agreement, "Work Product" means any
and all work product relating to Discoveries.

     b.  Executive shall promptly disclose to the Company all Discoveries and
Work Product.  All such disclosures must include complete and accurate copies of
all source code, object code or machine-readable copies, documentation, work
notes, flow-charts, diagrams, test data, reports, samples, and other tangible
evidence or results (collectively, "Tangible Embodiments") of such Discoveries
or Work Product.  All Tangible Embodiments of any Discoveries or Work Product
will be deemed to have been assigned to the Company as a result of the act of
expressing any Discovery or Work Product therein.

     c.  Executive hereby assigns and agrees to assign to the Company all of his
interest in any country in any and all Discoveries and Work Product, whether
such interest arises under patent law, copyright law, trade-secret law,
semiconductor chip protection law, or otherwise.  Without 

                                       8
<PAGE>
 
limiting the generality of the preceding sentence, Executive hereby authorizes
the Company to make any desired changes to any part of any Discovery or Work
Product, to combine it with other materials in any manner desired, and to
withhold Executive's identity in connection with any distribution or use thereof
alone or in combination with other materials. This assignment and assignment
obligation applies to all Discoveries and Work Product arising during
Executive's employment with the Company (or its predecessors), whether pursuant
to this Agreement or otherwise.

     d.  At the request of the Company, Executive shall promptly and without
additional compensation execute any and all patent applications, copyright
registration applications, waivers of moral rights, assignments, or other
instruments that the Company deems necessary or appropriate to apply for or
obtain Letters Patent of the United States or any foreign country, copyright
registrations or otherwise to protect the Company's interest in such Discovery
and Work Product, the expenses for which will be borne by the Company.
Executive hereby irrevocably designates and appoints the Company and its duly
authorized officers and agents as his agents and attorneys-in-fact to, if the
Company is unable for any reason to secure Executive's signature to any lawful
and necessary document required or appropriate to apply for or execute any
patent application, copyright registration application, waiver of moral rights,
or other similar document with respect to any Discovery and Work Product
(including, without limitation, renewals, extensions, continuations, divisions,
or continuations in part), (I) act for and in his behalf, (ii) execute and file
any such document, and (iii) do all other lawfully permitted acts to further the
prosecution of the same legal force and effect as if executed by him; this
designation and appointment constitutes an irrevocable power of attorney coupled
with an interest.

     e.  To the extent that any Discovery or Work Product constitutes
copyrightable or similar subject matter that is eligible to be treated as a
"work made for hire" or as having similar status in the United States or
elsewhere, it will be so deemed.  This provision does not alter or limit
Executive's other obligations to assign intellectual property rights as provided
above.

     f.  The obligations of Executive set forth in this Section 6 (including,
without limitation, the assignment obligations) will survive and continue
beyond the termination of Executive's employment and termination of this
Agreement with respect to Discoveries and Work Product conceived or made by
Executive alone or in concert with others during Executive's employment with the
Company.  Those obligations will be binding upon Executive, his executors,
administrators, and other representatives.

7.   Exposure to Proprietary Information.

     a.  As used in this Agreement, "Proprietary Information" means all
information of a business or technical nature that relates to the Company
including, without limitation, all information about software products whether
currently released or in development, all inventions, discoveries, improvements,
copyrightable work, source code, know-how, processes, designs, algorithms,
computer programs and routines, formulae and techniques, and any information
regarding the business of any customer or supplier of the Company or any other
information that the Company is 

                                       9
<PAGE>
 
required to keep confidential. Notwithstanding the preceding sentence, the term
"Proprietary Information" does not include information that is or becomes
publicly available through no fault of Executive.

     b.  Executive acknowledges that the Proprietary Information constitutes a
protectible business interest of the Company, and covenants and agrees that
during and after the term of his employment by the Company or, he will not,
directly or indirectly, disclose, furnish, make available or utilize any of the
Proprietary Information, other than in the proper performance of his duties for
the Company.  Executive's obligations under this Section 7 with respect to
particular Proprietary Information will survive expiration or termination of
this Agreement and Executive's employment with the Company, and will terminate
only at such time (if any) as the Proprietary Information in question becomes
generally known to the public other than through a breach of Executive's
obligations under this Section 7.

     c.  Executive acknowledges that all records, documents, and Tangible
Embodiments containing or of Proprietary Information prepared by Executive or
coming into his possession by virtue of his employment by the Company are and
will remain the property of the Company.  Upon termination of his employment
with the Company, Executive shall immediately return to the Company all such
items in his possession and all copies of such items.

8.   Equitable Remedies.

     a.  Executive acknowledges and agrees that the agreements and covenants set
forth in Sections 6, 7, and 8 are reasonable and necessary for the protection of
the Company's business interests, that irreparable injury will result to the
Company if Executive breaches any of the terms of said covenants, and that in
the event of Executive's actual or threatened breach of any such covenants, the
Company will have no adequate remedy at law.  Executive accordingly agrees that,
in the event of any actual or threatened breach by him of any of said covenants,
the Company will be entitled to immediate injunctive and other equitable relief,
without bond and without the necessity of showing actual monetary damages.
Nothing in this Section 8 will be construed as prohibiting the Company from
pursuing any other remedies available to it for such breach or threatened
breach, including the recovery of any damages that it is able to prove.

     b.  Each of the covenants in Sections 6, 7, and 8 will be construed as
independent of any other covenants or other provisions of this Agreement.

     c.  In the event of any judicial determination that any of the covenants in
Sections 6, 7, and 8 are not fully enforceable, it is the intention and desire
of the parties that the court treat said covenants as having been modified to
the extent deemed necessary by the court to render them reasonable and
enforceable, and that the court enforce them to such extent.

9.   Termination.  The Company may terminate this Agreement at any time, for any
reason or no reason by written notice to Executive, provided that a Change in
Control has not yet occurred at the 

                                       10
<PAGE>
 
time such notice is given and does not occur within 90 days after the notice of
termination has been given by the Company to Executive, and in such cases such

                longer than twelve (12) months from the date of issuance.

          (v)   the Borrower shall have delivered to the Issuer at such times 
                and in such manner as the Issuer may reasonably prescribe such
                documents and materials as may be required pursuant to the terms

                                       18
<PAGE>
 
                of the proposed Facility Letter of Credit and the proposed
                Facility Letter of Credit shall be reasonably satisfactory to
                the Issuer as to form and content; and

          (vi)  as of the date of issuance, no order, judgment or decree of any
                court, arbitrator or governmental authority shall purport by its
                terms to enjoin or restrain the Issuer from issuing the Facility
                Letter of Credit and no law, rule or regulation applicable to
                the Issuer and no request or directive (whether or not having
                the force of law) from any governmental authority with
                jurisdiction over the Issuer shall prohibit or request that the
                Issuer refrain from the issuance of Facility Letters of Credit
                generally or the issuance of that Facility Letter of Credit.

          2.2.3  Procedure for Issuance of Facility Letters of Credit. (a) The
Borrower shall give the Issuer one Business Day's prior written notice of any
requested issuance of a Facility Letter of Credit under this Agreement (except
that, in lieu of such written notice, the Borrower may give the Issuer
telephonic notice of such request if confirmed in writing by delivery to the
Issuer (i) immediately of a telecopy of the written notice required hereunder
which has been signed by an Authorized Officer containing all information
required to be contained in such written notice and (ii) promptly (but in no
event later than the requested time of issuance) of a copy of the written notice
required hereunder containing the original signature of an Authorized Officer);
such notice shall be irrevocable and shall specify the stated amount of the
Facility Letter of Credit requested, the effective date (which day shall be a
Business Day) of issuance of such requested Facility Letter of Credit, the date
on which such requested Facility Letter of Credit is to expire (which date shall
be a Business Day and shall in no event be later than twelve (12) months from
the issuance date), the purpose for which such Facility Letter of Credit is to
be issued, and the Person for whose benefit the requested Facility Letter of
Credit is to be issued and the currency in which it is to be issued, if not U.S.
Dollars.  At the time such request is made, the Borrower shall also provide the
Issuer with a copy of the form of the Facility Letter of Credit it is requesting
be issued.  Such notice, to be effective, must be received by the Issuer not
later than 2:00 P.M. (Chicago time) or the time agreed upon by the Issuer and
the Borrower on the last Business Day on which notice can be given under this
Section 2.2.3(a). The Issuer shall within one Business Day of any requested
issuance of a Facility Letter of Credit forward to the Lenders a copy of the
Borrower's request for the issuance of a Facility Letter of Credit hereunder.

     (b) Subject to the terms and conditions of this Section 2.2.3 and provided
that the applicable conditions set forth in Sections 4.2 and 2.2.2 hereof have
been satisfied, the Issuer shall, on the requested date, issue a Facility Letter
of Credit on behalf of the Borrower in accordance with the Issuer's usual and
customary business practices.

     (c) The Issuer shall not extend or amend any Facility Letter of Credit
unless the requirements of this Section 2.2.3 are met as though a new Facility
Letter of Credit was being requested and issued.

          2.2.4  Reimbursement Obligations.

     (a) The Borrower agrees to pay to the Issuer, for the account of the
Lenders, as applicable, the amount of all Reimbursement Obligations, interest
and other amounts payable to the Issuer under or in connection with any Facility
Letter of Credit immediately when due, irrespective of any claim, set-off,
defense or other right which the Borrower or any Subsidiary may have at any time
against the Issuer or any other Person, under all circumstances, including
without limitation, any of the following circumstances:

          (i)   any lack of validity or enforceability of this Agreement or any
                of the other Loan Documents;

          (ii)  the existence of any claim, setoff, defense or other right which
                the Borrower or any Subsidiary may have at any time against a
                beneficiary named in a Facility Letter of Credit or any
                transferee of any Facility Letter of Credit (or any Person for
                whom any such transferee may be acting), the Issuer, any Lender,
                or any other Person, whether in connection with this Agreement,
                any Facility Letter of Credit, the transactions contemplated
                herein or any unrelated transactions (including any underlying
                transactions between the Borrower or any Subsidiary and the
                beneficiary named in any Facility Letter of Credit);

          (iii) any draft, certificate or any other document presented under
                the Facility Letter of Credit proving to be forged, fraudulent,
                invalid or insufficient in any respect or any statement therein
                being untrue or inaccurate in any respect;

          (iv)  the surrender or impairment of any security for the performance
                or observance of any of the terms of any of the Loan Documents;
                or

          (v)   the occurrence of any Default or Unmatured Default.

     (b) The Issuer shall promptly notify the Borrower of any draw under a
Facility Letter of Credit.  The Borrower shall reimburse the Issuer, for the
account of the Lenders, as applicable, for drawings under a Facility Letter of
Credit issued by it no later than the Business Day after the payment by the
Issuer.  Unless the Borrower shall have made such payment to the Issuer on such
date, the Borrower shall be deemed to have elected to fulfill its Reimbursement
Obligation by requesting a Loan in an amount equal to the amount paid by the
Issuer in respect of such drawing under the Letter of Credit.  No Borrowing
Notice from the Borrower shall be required and such Loan shall be disbursed by
the Lenders notwithstanding any failure to satisfy any conditions for
disbursement of a Loan set forth in Article IV hereof (including restatement of
all representations and warranties) and, to the extent of the Loans so
disbursed, the Reimbursement Obligation of the Borrower hereunder shall be
deemed satisfied.  If any Reimbursement Obligation with respect to any Facility
Letter of Credit is not paid by the Borrower and there is no

                                       20
<PAGE>
 
availability to make a Loan under Section 2.1, then the Reimbursement Obligation
shall bear interest from the date of the relevant drawing under the pertinent
Facility Letter of Credit until the fifth Business Day following such drawing at
the Alternate Base Rate in effect for each such day and thereafter until paid at
the interest rate for past due Alternate Base Rate Loans calculated in
accordance with Section 2.11.

          2.2.5  Participation. (a) Immediately upon issuance by the Issuer of
any Facility Letter of Credit in accordance with the procedures set forth in
Section 2.2.3, each Lender shall be deemed to have irrevocably and
unconditionally purchased and received from the Issuer (without recourse or
warranty to the Issuer) an undivided interest and participation equal to its Pro
Rata Share in such Facility Letter of Credit (including, without limitation, all
obligations of the Borrower with respect thereto) and any security therefor or
guaranty pertaining thereto; provided, that a Facility Letter of Credit issued
by the Issuer shall not be deemed to be a Facility Letter of Credit for purposes
of this Section 2.2.5 if the Issuer shall have received written notice from any
Lender on or before one Business Day prior to the date of its issuance of such
Facility Letter of Credit that one or more of the conditions contained in
Section 4.2 is not then satisfied, and, in the event the Issuer receives such a
notice, it shall have no further obligation to issue any Facility Letter of
Credit until such notice is withdrawn by that Lender or such condition has been
effectively waived in accordance with the provisions of this Agreement.

     (b) In the event that the Issuer makes any payment under any Facility
Letter of Credit and the Borrower shall not have repaid such amount to the
Issuer pursuant to Section 2.2.4, the Issuer shall promptly notify each Lender
of such failure, and each Lender shall promptly and unconditionally pay to the
Agent for the account of the Issuer the amount of such Lender's Pro Rata Share
of the unreimbursed amount of any such payment.  If any Lender fails to make
available to the Issuer, any amounts due to the Issuer pursuant to this Section
2.2.5(b), the Issuer shall be entitled to recover such amount, together with
interest thereon at the Federal Funds Effective Rate, for the first three
Business Days after such Lender receives such notice and thereafter, at the
Alternate Base Rate, payable (i) on demand, (ii) by setoff against any payments
made to the Issuer for the account of such Lender or (iii) by payment to the
Issuer by the Agent of amounts otherwise payable to such Lender under this
Agreement.  The failure of any Lender to make available to the Agent its Pro
Rata Share of the unreimbursed amount of any such payment shall not relieve any
other Lender of its obligation hereunder to make available to the Agent its Pro
Rata Share of the unreimbursed amount of any payment on the date such payment is
to be made, but no Lender shall be responsible for the failure of any other
Lender to make available to the Agent its Pro Rata Share of the unreimbursed
amount of any payment on the date such payment is to be made.

     (c) Whenever the Issuer receives a payment on account of a Reimbursement
Obligation, including any interest thereon, it shall pay, on the same Business
Day the payment is received if received before noon (Chicago time) and on the
next Business Day if received after noon (Chicago time), to each Lender which
has funded its participating interest therein, in immediately available funds,
an amount equal to such Lender's Pro Rata Share thereof.

                                       21
<PAGE>
 
     (d) The obligations of a Lender to make payments to the Issuer with respect
to a Facility Letter of Credit shall be absolute, unconditional and irrevocable,
not subject to any counterclaim, set-off, qualification or exception whatsoever
and shall be made in accordance with the terms and conditions of this Agreement
under all circumstances.

     (e) In the event any payment by the Borrower or any Subsidiary received by
the Issuer with respect to a Facility Letter of Credit and distributed to the
Lenders on account of their participations is thereafter set aside, avoided or
recovered from the Issuer or the Agent in connection with any receivership,
liquidation, reorganization or bankruptcy proceeding, each Lender which received
such distribution shall, upon demand by the Agent or the Issuer, contribute such
Lender's Pro Rata Share of the amount set aside, avoided or recovered together
with interest at the rate required to be paid by the Agent or the Issuer upon
the amount required to be repaid by it.

          2.2.6  Compensation for Facility Letters of Credit.  The Borrower
agrees to pay to the Issuer a letter of credit fee equal to (i) 1% per annum on
the average daily undrawn amount (calculated at the U.S. Dollar Equivalent) of
each outstanding Standby Letter of Credit for the period from and including the
date of issuance of such Standby Letter of Credit to and including the
expiration of such Standby Letter of Credit, payable annually in advance and
(ii) a fee to be negotiated between the Borrower and the Issuer at the time of
issuance of a Commercial Letter of Credit, such fee to be payable annually in
advance. The letter of credit fees shall be distributed to the Lenders on a
monthly basis in accordance with their respective Pro Rata Shares.  Such fees
are nonrefundable and the Borrower shall not be entitled to any rebate of any
portion thereof if a Facility Letter of Credit does not remain outstanding
through its stated expiry date or for any other reason.  The Borrower further
agrees to pay to the Issuer, on demand, such other customary and reasonable
administrative fees, charges and expenses of the Issuer in respect of the
issuance, negotiation, acceptance, amendment, transfer and payment of a Letter
of Credit or otherwise payable pursuant to the application and related
documentation under which such Facility Letter of Credit is issued in accordance
with a schedule of fees provided by the Issuer to the Borrower.

          2.2.7  Letter of Credit Collateral Account.  The Borrower hereby
agrees that it will, until the final expiration date of any Facility Letter of
Credit and thereafter as long as any amount is payable to the Issuer or the
Lenders in respect of any Facility Letter of Credit and whether or not this
Agreement is then in effect, maintain a special collateral account (the "Letter
of Credit Collateral Account") at the Agent's office at the address specified
pursuant to Article XIV, in the name of the Borrower but under the sole dominion
and control of the Agent, for the benefit of the Lenders and in which the
Borrower shall have no interest other than as set forth in Section 9.1.  If this
Agreement terminates and any Letters of Credit remain outstanding beyond the
Facility Termination Date, the Borrower shall, prior to the Facility Termination
Date, (i) deposit in the Letter of Credit Collateral Account for the benefit of
the Agent and the Lenders, an amount equal to 100% of the sum of the aggregate
maximum amount remaining available to be drawn under the remaining outstanding
Facility Letters of Credit (assuming compliance with all conditions

                                       22
<PAGE>
 
for drawing thereunder), (herein the "Collateral Amount"), or (ii) deliver to
the Agent for the benefit of the Lenders, assets of the type described in the
definition of "Cash and Cash Equivalents" having a face amount, which when
discounted at the Agent's customary advance rate for collateral of that type, is
at least equal to the Collateral Amount, plus such pledge agreements, financing
statements, control agreements and other documents requested by the Agent in
order to perfect a first and prior perfected security interest in such assets in
favor of the Agent and the Lenders or (iii) provide the Agent for the benefit of
the Lenders with a letter(s) of credit in an aggregate amount at least equal to
the Collateral Amount, such letter(s) of credit to be in form and substance, and
issued by banks, satisfactory to the Agent. Such Letter of Credit Collateral
Account shall be maintained by the Agent in accordance with the provisions of
Section 9.1. The Agent will invest any funds on deposit from time to time in the
Letter of Credit Collateral Account in assets of the type described in said
"Cash and Cash Equivalent" definition, as directed by the Borrower from time to
time.

          2.2.8  Nature of Obligations. (a) As among the Borrower, the Issuer
and the Lenders, the Borrower assumes all risks of the acts and omissions of, or
misuse of the Facility Letters of Credit by, the respective beneficiaries of the
Facility Letters of Credit.  In furtherance and not in limitation of the
foregoing, the Issuer and the Lenders shall not be responsible for (i) the
forms, validity, sufficiency, accuracy, genuineness or legal effect of any
document submitted by any party in connection with the application for and
issuance of any Facility Letter of Credit, even if it should in fact prove to be
in any or all respects invalid, insufficient, inaccurate, fraudulent or forged;
(ii) the validity or sufficiency of any instrument transferring or assigning or
purporting to transfer of assign a Facility Letter of Credit or the rights or
benefits thereunder or proceeds thereof, in whole or in part, which may prove to
be invalid or ineffective for any reason; (iii) failure of the beneficiary of a
Facility Letter of Credit to comply fully with conditions required in order to
draw upon such Facility Letter of Credit; (iv) errors, omissions, interruptions
or delays in transmission or delivery of any messages, by mail, cable,
telegraph, telex or otherwise; (v) errors in interpretation of technical terms;
(vi) misapplication by the beneficiary of a Facility Letter of Credit of the
proceeds of any drawing under such Facility Letter of Credit; and (viii) any
consequences arising from causes beyond the control of the Issuer or the Lenders
and to the extent not avoidable by the Issuer or the Lender by the observance of
reasonable commercial standards prevailing in the geographic area where the
Agent is located.  Notwithstanding the foregoing, nothing contained herein shall
be deemed to relieve the Issuer or any Lender from responsibility for any of the
foregoing consequences to the extent arising from the Issuer or such Lender's
willful or intentional breach of the terms hereof or its gross negligence.

     (b) In furtherance and extension and not in limitation of the specific
provisions hereinabove set forth, any action taken or omitted by the Issuer or
any Lender under or in connection with the Facility Letters of Credit or any
related certificates, if taken or omitted in good faith, shall not put the
Issuer or such Lender under any resulting liability to the Borrower or relieve
the Borrower of any of its obligations hereunder to the Issuer, the Agent or any
Lender.

                                       23

     2.3  Ratable Loans.  Each Advance hereunder shall consist of Loans made
from the several Lenders ratably in proportion to the ratio that their
respective Commitments bear to the Aggregate Commitment.

     2.4  Types of Advances.  The Advances may be Alternate Base Rate Advances
or Eurodollar Advances, or a combination thereof, selected by the Borrower in
accordance with Sections 2.8 and 2.9.

     2.5  Commitment Fee; Reductions in Aggregate Commitment.  The Borrower
agrees to pay to the Agent for the account of each Lender a commitment fee of 20
basis points per annum on the daily unborrowed portion of such Lender's
Commitment from the date hereof to and including the Facility Termination Date,
payable on each Payment Date hereafter and on the Facility Termination Date.  In
calculating the unborrowed portion of a Lender's Commitment, the undrawn amount
of any outstanding Commercial Letters of Credit will not be considered usage,
but the undrawn amount of any outstanding Standby Letters of Credit will be
considered usage.

     The Borrower may permanently reduce the Aggregate Commitment in whole, or
in part ratably among the Lenders in integral multiples of $5,000,000 upon at
least ten Business Days' written notice to the Agent, which notice shall specify
the amount of any such reduction, provided, however, that the amount of the
Aggregate Commitment may not be reduced below the aggregate principal amount of
the outstanding Advances and Facility Letter of Credit Obligations.  All accrued
commitment fees shall be payable on the effective date of any termination of the
obligations of the Lenders to make Loans hereunder.

     2.6  Minimum Amount of Each Advance.  Each Eurodollar Advance shall be in
the minimum amount of $1,000,000 (and in multiples of $100,000 in excess
thereof), and each Alternate Base Rate Advance shall be in the minimum amount of
$100,000 (and in multiples of $10,000 in excess thereof), provided, however,
that any Alternate Base Rate Advance may be in the amount of the unused
Aggregate Commitment.

     2.7  Optional Principal Payments.  The Borrower may from time to time pay,
without penalty or premium, all outstanding Alternate Base Rate Advances, or, in
a minimum aggregate amount of $100,000 and in integral multiples of $10,000 in
excess thereof, any portion of the outstanding Alternate Base Rate Advances upon
two Business Days' prior notice to the Agent.  A Eurodollar Advance may be paid
prior to the last day of the applicable Eurodollar Interest Period only upon
payment of any amounts due under Section 3.4 in connection with such prepayment.

     2.8  Method of Selecting Types and Eurodollar Interest Periods for New
Advances.  The Borrower shall select the Type of Advance and, in the case of
each Eurodollar Advance, the Eurodollar Interest Period applicable to each
Advance from time to time.  The Borrower shall give the Agent irrevocable notice
(a "Borrowing Notice") not later than 10:00 a.m. (Chicago time) at least one
Business Day before the Borrowing Date of each Alternate Base Rate Advance, and
two Business Days before the Borrowing 

                                       24

<PAGE>
 
Date for each Eurodollar Advance, specifying:

          (i)   the Borrowing Date, which shall be a Business Day, of such
                Advance,

          (ii)  the aggregate amount of such Advance,

          (iii) the Type of Advance selected, and

          (iv)  in the case of each Eurodollar Advance, the Eurodollar Interest
                Period applicable thereto.

The Agent shall give each Lender notice of the Borrowing Notice on the Business
Day on which such Borrowing Notice was received by Agent.  Not later than noon
(Chicago time) on each Borrowing Date, each Lender shall make available its Loan
or Loans, in funds immediately available in Chicago to the Agent at its address
specified pursuant to Article XIV.  The Agent will make the funds so received
from the Lenders available to the Borrower at the Agent's aforesaid address.

     2.9  Conversion and Continuation of Outstanding Advances. Alternate Base
Rate Advances shall continue as Alternate Base Rate Advances unless and until
such Alternate Base Rate Advances are converted into Eurodollar Advances.  Each
Eurodollar Advance shall continue as a Eurodollar Advance until the end of the
then applicable Eurodollar Interest Period therefor, at which time such
Eurodollar Advance shall be automatically converted into a Alternate Base Rate
Advance unless the Borrower shall have given the Agent a Conversion/Continuation
Notice requesting that, at the end of such Eurodollar Interest Period, such
Eurodollar Advance either continue as a Eurodollar Advance for the same or
another Interest Period. Subject to the terms of Section 2.6, the Borrower may
elect from time to time to convert all or any part of an Advance of any Type
into any other Type or Types of Advances; provided that any conversion of any
Eurodollar Advance shall be made on, and only on, the last day of the Eurodollar
Interest Period applicable thereto.  The Borrower shall give the Agent
irrevocable notice (a "Conversion/Continuation Notice") of each conversion of an
Advance or continuation of a Eurodollar Advance not later than 10:00 a.m.
(Chicago time) at least one Business Day, in the case of a conversion into a
Alternate Base Rate Advance, or two Business Days, in the case of a conversion
into or continuation of a Eurodollar Advance, prior to the date of the requested
conversion or continuation, specifying:

          (i)   the requested date which shall be a Business Day, of such
                conversion or continuation,

          (ii)  the aggregate amount and Type of the Advance which is to be
                converted or continued, and

          (iii) the amount and Type(s) of Advance(s) into which such Advance is
                to be converted or continued and, in the case of a conversion
                into or 

                                       25
<PAGE>
 
               continuation of an Alternate Base Rate Advance, the duration of
               the Eurodollar Interest Period applicable thereto.

     2.10  Changes in Interest Rate, etc. Each Alternate Base Rate Advance shall
bear interest on the outstanding principal amount thereof, for each day from and
including the date such Advance is made or is converted from a Eurodollar
Advance into an Alternate Base Rate Advance pursuant to Section 2.9 to but
excluding the date it becomes due or is converted into a Eurodollar Advance
pursuant to Section 2.9 hereof, at a rate per annum equal to the Alternate Base
Rate for such day.  Changes in the rate of interest on that portion of any
Advance maintained as an Alternate Base Rate Advance will take effect
simultaneously with each change in the Alternate Base Rate.  Each Eurodollar
Advance shall bear interest on the outstanding principal amount thereof from and
including the first day of the Interest Period applicable thereto to (but not
including) the last day of such Eurodollar Interest Period at the interest rate
determined as applicable to such Eurodollar Advance.  No Eurodollar Interest
Period may end after the Facility Termination Date.

     2.11  Rates Applicable After Default.  Notwithstanding anything to the
contrary contained in Section 2.8 or 2.9, during the continuance of a Default or
Unmatured Default the Required Lenders may, at their option, by notice to the
Borrower (which notice may be revoked at the option of the Required Lenders
notwithstanding any provision of Section 9.2 requiring unanimous consent of the
Lenders to changes in interest rates), declare that no Advance may be made as,
converted into or continued as a Eurodollar Advance.  During the continuance of
a Default, the Required Lenders may, at their option, by notice to the Borrower
(which notice may be revoked at the option of the Required Lenders
notwithstanding any provision of Section 9.2 requiring unanimous consent of the
Lenders to changes in interest rates), declare that (i) each Eurodollar Advance
shall bear interest for the remainder of the applicable Eurodollar Interest
Period at the rate otherwise applicable to such Eurodollar Interest Period plus
2% per annum and (ii) each Alternate Base Rate Advance shall bear interest at a
rate per annum equal to the Alternate Base Rate plus 2% per annum.

     2.12  Method of Payment.  All payments of the Obligations hereunder shall 
be made, without setoff, deduction, or counterclaim, in immediately available
funds to the Agent at the Agent's address specified pursuant to Article XIV, or
at any other Lending Installation of the Agent specified in writing by the Agent
to the Borrower, by noon (local time) on the date when due and shall be applied
ratably by the Agent among the Lenders. Each payment delivered to the Agent for
the account of any Lender shall be delivered by the Agent to such Lender on the
same Business Day such payment is received if received prior to noon (Chicago
time) and on the next Business Day if received after noon (Chicago time), shall
be in the same type of funds that the Agent received and shall be delivered to
its address specified pursuant to Article XIV or at any Lending Installation
specified in a notice received by the Agent from such Lender. When directed by
telephonic, facsimile or written notice, from an Authorized Officer, the Agent
is hereby authorized to charge the account of the Borrower maintained with ANB
for each payment of principal, interest and fees as it becomes due hereunder.

                                       26
<PAGE>
 
     2.13  Notes; Telephonic Notices.  Each Lender is hereby authorized to 
record the principal amount of each of its Loans and each repayment on the
schedule attached to its Note, provided, however, that neither the failure to so
record nor any error in such recordation shall affect the Borrower's obligations
under such Note. The Borrower hereby authorizes the Lenders and the Agent to
extend, convert or continue Advances, effect selections of Types of Advances and
to transfer funds based on telephonic notices made by any Person or Persons the
Agent or any Lender in good faith believes to be acting on behalf of the
Borrower. The Borrower agrees to deliver promptly to the Agent a written
confirmation signed by an Authorized Officer, if such confirmation is requested
by the Agent or any Lender, of each telephonic notice. If the written
confirmation differs in any material respect from the action taken by the Agent
and the Lenders, the records of the Agent and the Lenders shall govern absent
manifest error.

     2.14  Interest Payment Dates; Interest and Fee Basis.  Interest accrued on
each Alternate Base Rate Advance shall be payable on each Payment Date,
commencing with the first such date to occur after the date hereof, on any date
on which the Alternate Base Rate Advance is prepaid, whether due to acceleration
or otherwise, and at maturity.  Interest accrued on that portion of the
outstanding principal amount of any Alternate Base Rate Advance converted into a
Eurodollar Advance on a day other than a Payment Date shall be payable on the
date of conversion.  Interest accrued on each Eurodollar Advance shall be
payable on the last day of its applicable Interest Period, on any date on which
the Eurodollar Advance is prepaid, whether by acceleration or otherwise, and at
maturity.  Interest accrued on each Eurodollar Advance having a Eurodollar
Interest Period longer than three months shall also be payable on the last day
of each three-month interval during such Eurodollar Interest Period.  Interest
and commitment fees shall be calculated for actual days elapsed on the basis of
a 360-day year.  Interest shall be payable for the day an Advance is made but
not for the day of any payment on the amount paid if payment is received prior
to noon (local time) at the place of payment.  If any payment of principal of or
interest on an Advance shall become due on a day which is not a Business Day,
such payment shall be made on the next succeeding Business Day and, in the case
of a principal payment, such extension of time shall be included in computing
interest in connection with such payment.

     2.15  Notification of Advances, Interest Rates, Prepayments and Commitment
Reductions.  Promptly after receipt thereof (and on the same Business Day as
received by the Agent with respect to Borrowing and Conversion/Continuation
Notices), the Agent will notify each Lender of the contents of each Aggregate
Commitment reduction notice, Borrowing Notice, Conversion/Continuation Notice,
and repayment notice received by it hereunder.  The Agent will notify each
Lender of the interest rate applicable to each Eurodollar Advance within two
Business Days of determination of such interest rate and will give each Lender
prompt notice of each change in the Alternate Base Rate.

     2.16  Lending Installations.  Each Lender may book its Loans at any Lending
Installation selected by such Lender and may change its Lending Installation
from time to time.  All terms of this Agreement shall apply to any such Lending
Installation and the 

                                       27
<PAGE>
 
Notes shall be deemed held by each Lender for the benefit of such Lending
Installation. Each Lender may, by written or telex notice to the Agent and the
Borrower, designate a Lending Installation through which Loans will be made by
it and for whose account Loan payments are to be made.

     2.17  Non-Receipt of Funds by the Agent.  Unless the Borrower or a Lender,
as the case may be, notifies the Agent prior to the date on which it is
scheduled to make payment to the Agent of (i) in the case of a Lender, the
proceeds of a Loan or (ii) in the case of the Borrower, a payment of principal,
interest or fees to the Agent for the account of the Lenders, that it does not
intend to make such payment, the Agent may assume that such payment has been
made.  The Agent may, but shall not be obligated to, make the amount of such
payment available to the intended recipient in reliance upon such assumption.
If such Lender or the Borrower, as the case may be, has not in fact made such
payment to the Agent, the recipient of such payment shall, on demand by the
Agent, repay to the Agent the amount so made available together with interest
thereon in respect of each day during the period commencing on the date such
amount was so made available by the Agent until the date the Agent recovers such
amount at a rate per annum equal to (i) in the case of payment by a Lender, the
Federal Funds Effective Rate for such day or (ii) in the case of payment by the
Borrower, the interest rate applicable to the relevant Loan.

     2.18  Mandatory Prepayments.

          2.18.1  Change in Control.  Within 30 Business Days prior to the
consummation of any transaction which would cause a Change in Control and which
is scheduled to close prior to the Facility Termination Date, the Borrower shall
notify (a "Change in Control Notice") the Agent of such expected transaction,
including within such Change in Control Notice the expected closing date of such
transaction, if known by the Borrower.  The Agent shall promptly deliver a copy
of such notice to each Lender.  Within 10 Business Days of receipt of such
Change in Control Notice by the Agent and the Lenders, the Required Lenders may,
at their option, give notice to the Agent and the Borrower that the Lenders
elect to terminate their Commitment hereunder.  Unless an earlier date is
otherwise agreed upon between the Borrower, the Agent and the Required Lenders,
the Aggregate Commitment shall terminate simultaneously with the closing of such
transaction and the Borrower shall repay at such time all outstanding Advances,
together with accrued interest thereon, any accrued fees with respect to the
Aggregate Commitment, any costs, losses or expenses incurred by the Lenders in
connection with such prepayment payable by the Borrower pursuant to Section 3.4,
provide cash collateral for all outstanding Facility Letters of Credit in
accordance with Section 2.18.4 and pay any other obligations of the Borrower to
the Lenders hereunder.

     For purposes of this Agreement, the term "Change in Control" shall mean
each of the following: (i) any Person or "group" (as such term is defined in
Section 13(d) of the Securities Act of 1934, as said Act is amended from time to
time), other than a Subsidiary or employee benefit plan of Borrower, which is
not as of the Effective Date the legal or beneficial owner of fifty percent
(50%) or more of the common Stock of the Borrower or 

                                       28
<PAGE>
 
voting securities of the Borrower representing fifty percent (50%) or more of
the combined voting power of all voting securities of the Borrower, becomes the
owner of fifty percent (50%) or more of such common Stock or voting securities
after the Effective Date; or (ii) approval by the stockholders of the Borrower
of any merger, reorganization or consolidation with respect to which the Persons
who were the respective legal and beneficial owners of the Borrower's Stock
immediately before such merger, reorganization or consolidation do not
thereafter beneficially and legally own, directly or indirectly, more than 50%
of both the common Stock and/or combined voting power of the securities of the
corporation or other entity which results from such merger, reorganization or
consolidation.

          2.18.2  Outstandings Exceed Aggregate Commitment.  If at any time for
any reason, the total of the then outstanding Advances plus the amount of the
U.S. Dollar Equivalent of all Facility Letter of Credit Obligations exceeds the
Aggregate Commitment, as then in effect, the Borrower shall immediately prepay
Advances and/or provide cash collateral in accordance with Section 2.18.4 in an
amount sufficient so that after giving effect thereto, the total of the
outstanding Advances plus the amount of the U.S. Dollar Equivalent of the
Facility Letter of Credit Obligations does not exceed the Aggregate Commitment.

          2.18.3  U.S. Dollar Equivalent.  Mandatory prepayments that would
otherwise be required pursuant to Section 2.18.2 solely as a result of
fluctuations in Exchange Rates from time to time shall only be required to be
made on the last Business Day of each month on the basis of the Exchange Rate in
effect on such Business Day.

          2.18.4  Letter of Credit Collateral Account.  Upon a mandatory
prepayment pursuant to this Section 2.18, the Borrower shall, upon request of
the Agent, deliver to the Agent security for the Facility Letters of Credit in
accordance with, and on the same terms and conditions as those set forth in,
Section 2.2.7, in an amount equal to, in the case of Section 2.18.1, 100% of the
sum of the aggregate maximum amount remaining available to be drawn under the
outstanding Facility Letters of Credit (assuming compliance with all conditions
for drawing thereunder) which will remain outstanding after the Facility
Termination Date and in the case of 2.18.2, an amount sufficient to cause the
sum of the outstanding Advances plus the U. S. Dollar Equivalent of the Facility
Letters of Credit not collateralized to not exceed the Aggregate Commitment.
Such Letter of Credit Collateral Account shall be maintained by the Agent in
accordance with the provisions of Section 9.1.

     2.19  Application of Payments with Respect to Defaulting Lenders.  No
payments of principal, interest or fees delivered to the Agent for the account
of any Defaulting Lender shall be delivered by the Agent to such Defaulting
Lender.  Instead, such payments shall, for so long as such Defaulting Lender
shall be a Defaulting Lender, be held by the Agent, and the Agent is hereby
authorized and directed by all parties hereto to hold such funds in escrow and
apply such funds as follows:
 
          (i)  First, if applicable, to any payments due to the Issuer pursuant
               to 

                                       29
<PAGE>
 
               Section 2.2.5(b); and

          (ii) Second, to Loans required to be made by such Defaulting Lender on
               any Borrowing Date to the extent such Defaulting Lender fails to
               make such Loans.

     Notwithstanding the foregoing, upon the termination of the Aggregate
Commitment and the payment and performance of all of the Obligations (other than
those owing to a Defaulting Lender), any funds then held in escrow by the Agent
pursuant to the preceding sentence shall be distributed to each Defaulting
Lender, pro rata in proportion to amounts that would be due to each Defaulting
Lender but for the fact that it is a Defaulting Lender.


                                  ARTICLE III

                            CHANGE IN CIRCUMSTANCES
                            -----------------------
     
     3.1  Yield Protection.  If, on or after the date of this Agreement, the
adoption of any law or any governmental or quasi-governmental rule, regulation,
policy, guideline or directive (whether or not having the force of law), or any
amendment to any existing law, rule, regulation, policy, guideline or directive
or any change in the interpretation thereof, by any governmental or quasi-
governmental authority, central bank, or comparable agency charged with the
interpretation or administration thereof, or compliance by any Lender or
applicable Lending Installation with any request or directive (whether or not
having the force of law) of any such authority, central bank or comparable
agency;

          (i)   subjects any Lender or any applicable Lending Installation to 
                any tax, duty, charge or withholding on or from payments due
                from the Borrower (excluding federal taxation of the overall net
                income of any Lender or applicable Lending Installation), or
                changes the basis of taxation of payments to any Lender in
                respect of its Loans or any Facility Letters of Credit or other
                amounts due it hereunder, or

          (ii)  imposes or increases or deems applicable any reserve, 
                assessment, insurance charge, special deposit or similar
                requirement against assets of, deposits with or for the account
                of, or credit extended by, any Lender or any applicable Lending
                Installation (other than reserves and assessments taken into
                account in determining the interest rate applicable to
                Eurodollar Advances), or

          (iii) imposes any other condition the result of which is to increase
                the cost to any Lender or any applicable Lending Installation of
                making, funding or maintaining loans or reduces any amount
                receivable by any Lender or any applicable Lending Installation
                in connection with loans, or requires any Lender or any
                applicable Lending Installation to make any payment calculated
                by reference to the amount of loans held or interest received by
                it, by an amount deemed material by

                                       30
<PAGE>
 
               such Lender,

and the result of any of the foregoing is to increase the cost to such Lender or
applicable Lending Installation of making or maintaining its Loans, Facility
Letters of Credit or Commitment or to reduce the return received by such Lender
or applicable Lending Installation in connection with its Loans, Facility
Letters of Credit or Commitment, then, within 15 days of demand by such Lender,
the Borrower shall pay such Lender that portion of such increased expense
incurred or reduction in an amount received which such Lender determines is
attributable to making, funding and maintaining its Loans, any Facility Letters
of Credit and its Commitment.  Notwithstanding the foregoing, no Lender shall be
permitted to request payment hereunder for any increased cost or reduction in
amount received which was incurred more than 180 days prior to the date payment
is requested.

     3.2  Changes in Capital Adequacy Regulations.  If a Lender determines the
amount of capital required or expected to be maintained by such Lender, any
Lending Installation of such Lender or any corporation controlling such Lender
is increased as a result of a Change, then, within 15 days of demand by such
Lender, the Borrower shall pay such Lender the amount necessary to compensate
for any shortfall in the rate of return on the portion of such increased capital
which such Lender determines is attributable to this Agreement, its Loans or its
issuance of or participation in Facility Letters of Credit or its obligation to
make Loans or issue or participate in Facility Letters of Credit hereunder
(after taking into account such Lender's policies as to capital adequacy).
"Change" means (i) any change after the date of this Agreement in the Risk-Based
Capital Guidelines or (ii) any adoption of or change in any other law,
governmental or quasi-governmental rule, regulation, policy, guideline,
interpretation, or directive (whether or not having the force of law) after the
date of this Agreement which affects the amount of capital required or expected
to be maintained by any Lender or any Lending Installation or any corporation
controlling any Lender.  "Risk-Based Capital Guidelines" means (i) the risk-
based capital guidelines in effect in the United States on the date of this
Agreement, including transition rules, and (ii) the corresponding capital
regulations promulgated by regulatory authorities outside the United States
implementing the July 1988 report of the Basle Committee on Banking Regulation
and Supervisory Practices Entitled "International Convergence of Capital
Measurements and Capital Standards," including transition rules, and any
amendments to such regulations adopted prior to the date of this Agreement.

     3.3  Availability of Types of Advances.  If any Lender determines that
maintenance of its Eurodollar Loans at a suitable Lending Installation would
violate any applicable law, rule, regulation, or directive, whether or not
having the force of law, or if the Required Lenders determine that (i) deposits
of a type and maturity appropriate to match fund Eurodollar Advances are not
available or (ii) the interest rate applicable to a Type of Advance does not
accurately reflect the cost of making or maintaining such Advance, then the
Agent shall suspend the availability of the affected Type of Advance and if
maintenance of such Eurodollar Loans would violate any applicable law, rule,
regulation or directive, whether or not having the force of law, require any
Eurodollar Advances of the affected Type to be repaid, subject to the payment of
any funding 

                                       31
<PAGE>
 
indemnification amounts required by Section 3.4.

     3.4  Funding Indemnification.  If any payment of a Eurodollar Advance
occurs on a date which is not the last day of the applicable Interest Period,
whether because of acceleration, prepayment or otherwise, or a Eurodollar
Advance is not made, converted, or continued on the date specified by the
Borrower for any reason other than default by the Lenders, the Borrower will
indemnify each Lender for any loss or cost incurred by it resulting therefrom,
including, without limitation, any loss or cost in liquidating or employing
deposits acquired to fund or maintain the Eurodollar Advance.

     3.5  Lender Statements; Limitations on Liability, Survival of Indemnity.
To the extent reasonably possible, each Lender shall designate an alternate
Lending Installation with respect to its Eurodollar Loans to reduce any
liability of the Borrower to such Lender under Sections 3.1 and 3.2 or to avoid
the unavailability of a Type of Advance under Section 3.3, so long as such
designation is not disadvantageous to such Lender. The Borrower shall not be
liable to a Lender under Sections 3.1 or 3.2 above for any such increased costs
whose imposition was caused solely by the willful or intentional breach by such
Lender of the terms of this Agreement or by such Lender's gross negligence or
willful misconduct.  Each Lender shall deliver a written statement of such
Lender to the Borrower (with a copy to the Agent) as to the amount due, if any,
under Section 3.1, 3.2 or 3.4.  Such written statement shall set forth in
reasonable detail the calculations upon which such Lender determined such amount
and shall be presumptively correct in the absence of manifest error.
Determination of amounts payable under such Sections in connection with a
Eurodollar Loan shall be calculated as though each Lender funded its Eurodollar
Loan through the purchase of a deposit of the type and maturity corresponding to
the deposit used as a reference in determining the Eurodollar applicable to such
Loan, whether in fact that is the case or not.  Unless otherwise provided
herein, the amount specified in the written statement of any Lender shall be
payable on demand after receipt by the Borrower of such written statement.  The
obligations of the Borrower under Sections 3.1, 3.2 and 3.4 shall survive
payment of the Obligations and termination of this Agreement.


                                   ARTICLE IV

                CONDITIONS PRECEDENT; WITHHOLDING TAX EXEMPTION
                -----------------------------------------------

     4.1  Initial Advance.  The Lenders shall not be required to make the
initial Advance (or the Issuer issue the initial Facility Letter of Credit)

for its own account and the account of the Lenders under this Agreement and the
Borrower has furnished to the Agent with sufficient copies for the Lenders:

          (i)   Copies of the articles of incorporation (or other applicable

          (ii)   Copies, certified by the Secretary or Assistant Secretary of 
                 the Borrower and each Guarantor, of its by-laws and of its

                 bodies, if any are deemed necessary by counsel for any Lender)
                 authorizing the execution of the Loan Documents or the
                 Guaranties, as applicable.

          (iii)  An incumbency certificate, executed by the Secretary or
                 Assistant Secretary of the Borrower and each Guarantor, which
                 shall identify by name and title and bear the signature of the
                 officers of the Borrower or such Guarantor authorized to sign
                 the Loan Documents or the Guaranties, whichever is applicable,
                 and to make borrowings hereunder, upon which certificate the
                 Agent and the Lenders shall be entitled to rely until informed
                 of any change in writing by the Borrower or the applicable
                 Guarantor.

          (iv)   A certificate, signed by the chief financial officer of the
                 Borrower, stating that on the initial Borrowing Date and after
                 giving effect to the execution of this Agreement no Default or
                 Unmatured Default has occurred and is continuing and the
                 representations and warranties contained in Article V are true
                 and correct as of such date.

          (v)    A written opinion of the Borrower's counsel, addressed to the
                 Lenders in substantially the form of Exhibit "B" hereto.

          (vi)   Notes payable to the order of each of the Lenders.

          (vii)  Written money transfer instructions, in substantially the form

                 transfer authorizations as the Agent may have reasonably
                 requested.

          (viii) Consents to the amendments included herein executed by each of
                 the Guarantors.

          (ix)   Such other documents as any Lender or its counsel may have
                 reasonably requested.

     4.2  Each Advance.  The Lenders shall not be required to make any Advance
nor shall the Issuer be required to issue any Facility Letter of Credit (other
than an Advance that, after giving effect thereto and to the application of the
proceeds thereof, does not increase the aggregate amount of outstanding
Advances), unless on the applicable Borrowing Date or issuance date:

                                       33
<PAGE>
 
          (i)    There exists no Default or Unmatured Default.

          (ii)   The representations and warranties contained in Article V are
                 true and correct as of such Borrowing Date (or issuance date)
                 except to the extent any such representation or warranty is
                 stated to relate solely to an earlier date, in which case such
                 representation or warranty shall be true and correct on and as
                 of such earlier date.

          (iii)  All legal matters incident to the making of such Advance or the
                 issuance of a Facility Letter of Credit shall be satisfactory
                 to the Lenders and their counsel, or the Issuer or its counsel,
                 whichever is applicable.

     Each Borrowing Notice with respect to each such Advance and each request to
issue a Facility Letter of Credit shall constitute a representation and warranty
by the Borrower that the conditions contained in Sections 4.2(i) and (ii) have
been satisfied.  Any Lender or the Issuer may require a duly completed
compliance certificate in substantially the form of Exhibit "C" hereto as a
condition to making an Advance or issuing a Facility Letter of Credit.

     4.3  Withholding Tax Exemption. At least five Business Days prior to the
first date on which interest or fees are payable hereunder for the account of
any Lender, each Lender that is not incorporated under the laws of the United
States of America, or a state thereof, agrees that it will deliver to each of
the Borrower and the Agent two duly completed copies of United States Internal
Revenue Service Form 1001 or 4224, certifying in either case that such Lender is
entitled to receive payments under this Agreement and the Notes without
deduction or withholding of any United States federal income taxes.  Each Lender
which so delivers a Form 1001 or 4224 further undertakes to deliver to each of
the Borrower and the Agent two additional copies of such form (or a successor
form) on or before the date that such form expires (currently, three successive
calendar years for Form 1001 and one calendar year for Form 4224) or becomes
obsolete or after the occurrence of any event requiring a change in the most
recent forms so delivered by it, and such amendments thereto or extensions or
renewals thereof as may be reasonably requested by the Borrower or the Agent, in
each case certifying that such Lender is entitled to receive payments under this
Agreement and the Notes without deduction or withholding of any United States
federal income taxes, unless an event (including without limitation any change
in treaty, law or regulation) has occurred prior to the date on which any such
delivery would otherwise be required which renders all such forms inapplicable
or which would prevent such Lender from duly completing and delivering any such
form with respect to it and such Lender advises the Borrower and the Agent that
it is not capable of receiving payments without any deduction or withholding of
United States federal income tax.

                         REPRESENTATIONS AND WARRANTIES
                         ------------------------------

     5.1  Inducement.  To induce Lenders to enter into this Agreement and to
make the Loans and to induce the Issuer to issue Facility Letters of Credit,
Borrower makes the representations and warranties set forth in Sections 5.2
through 5.21 of this Agreement, which representations and warranties shall
survive the execution and delivery of this Agreement and the Loan Documents and
the making of the Loans and the issuance of the Facility Letters of Credit,
until such time as Borrower has indefeasibly paid and performed all the
Obligations owed to Lenders, Issuer and the Agent.  For purposes of this
Agreement, the "best knowledge" of Borrower shall mean the knowledge which a
reasonable, prudent, experienced individual in similar business circumstances
would have after a diligent inquiry into the subject matter at issue.
 
     5.2  Status.  Borrower: (i) is a duly organized and validly existing
corporation in good standing under the laws of the State of Delaware; (ii) has
the power and authority to own its property and assets and to transact the
business in which it is engaged or presently proposes to engage; and (iii) has
duly qualified and is authorized to do business and is in good standing as a
foreign corporation in every jurisdiction of every Governmental Authority in
which it owns or leases real property or in which the nature of its business
requires it to be so qualified, including but not limited to the State of
Illinois unless the failure to be so qualified could not have a Material Adverse
Effect.  Each Material Subsidiary: (i) is a corporation or similar limited
liability entity duly organized or created and validly existing under the laws
of its jurisdiction of incorporation or creation; (ii) has the power and
authority to own its property and assets and to transact the business in which
it is engaged or presently purposes to engage and (iii) has duly qualified
and/or is authorized to do business and, to the extent applicable, is in good
standing, as a foreign corporation or otherwise, in every jurisdiction of every
Governmental Authority in which it owns or leases real property or in which the
nature of its business requires it to be so qualified or authorized unless the
failure to be so qualified or authorized would not have a Material Adverse
Effect.  Borrower and each Material Subsidiary have paid and will continue to
pay all taxes, Charges, levies and other fees associated with such
qualifications or authorizations to the extent failure to pay would have a
Material Adverse Effect, and shall maintain the same in full force and effect.
 
     5.3  Power and Authority.  Borrower has full power and authority to
execute, deliver and perform the terms and provisions of each of the Loan
Documents and the Notes.  Borrower has taken all necessary and proper corporate
or other action to authorize its execution, delivery and performance of and
under such Loan Documents.  Borrower duly has executed and delivered each such
Loan Document, and each such Loan Document constitutes Borrower's legal, valid
and binding obligations, enforceable against it in accordance with said Loan
Documents' terms, except as bankruptcy, insolvency, similar laws which affect
creditors' rights generally or general equity principles may limit such
enforceability.
 
     5.4  Securities Matters.  Borrower did not issue any of its Stock or other
securities of any type or nature in violation of any securities or similar laws
of any 

                                       35
<PAGE>
 
Governmental Authority, nor, to Borrower's best knowledge, did any of its
Subsidiaries issue any of its Stock or securities of any type or nature in
violation of any securities or similar laws of any Governmental Authority.
 
     5.5  No Violation.  Neither Borrower's execution, delivery or performance
of, nor compliance with the terms and provisions of the Loan Documents nor the
consummation by the Borrower of the transactions contemplated by the Loan
Documents, either currently or with the passage of time or granting of notice,
will: (i) contravene any applicable provision of any law, statute, rule,
regulation, order, writ, injunction or decree of any court or Governmental
Authority; (ii) conflict or be inconsistent with or result in any breach of, any
terms, covenants, conditions or provisions of, constitute a default under, or
result in the creation or imposition of (or the obligation to create or impose)
any Lien upon any property or assets of Borrower or any Material Subsidiary,
pursuant to the terms of any indenture, mortgage, deed of trust, agreement,
bond, note, insurance policy, license or other instrument to which Borrower or
any Material Subsidiary is a party or by which Borrower or any Material
Subsidiary or any property or assets of Borrower or any Material Subsidiary are
bound or to which Borrower or any Material Subsidiary may be subject; or (iii)
will contravene, constitute a violation of constitute a default under or in any
manner conflict with the Articles of Incorporation, bylaws or other

furnished by or on behalf of Borrower or any of its Material Subsidiaries to

Material Subsidiaries have fulfilled and performed all of their material
obligations under each such Permit. No event has occurred or condition or state
of facts exists which constitutes, or after notice or lapse of time or both,
would constitute, a material breach or default under any such Permit, or would

<PAGE>
 
Permit and such default and/or revocation would have a Material Adverse Effect.
Neither Borrower or any Material Subsidiary has received notice of cancellation,
of default or of any material dispute concerning any such Permit. Each such
Permit is valid, subsisting and in full force and effect and to Borrower's best

(including, without limitation, all Environmental Laws), and all orders,
judgments, writs and decrees of any Governmental Authority applicable to any of
them or any of their assets both prior to closing and giving effect to the
closing of the Loan Documents where failure to so comply would have a Material
Adverse Effect.  To Borrower's best knowledge, there have been no legislative or
regulatory proposals adopted or pending which could have a Material Adverse
Effect on Borrower's or its Material Subsidiaries or businesses.
 
          5.13.2  Export Assurance.  Irrespective of any disclosure Borrower or
any Subsidiary may make to Agent or the Lenders of any ultimate destination for
any software products licensed, sold or distributed by Borrower or any
Subsidiary, Borrower and its Subsidiaries shall not export or re-export,
directly or indirectly, any software products or any technical data derived
therefrom, without first obtaining all necessary approvals or required export
licenses to do so from the United States Department of Commerce or any agency of
the United States Government or of any Other Nation or Governmental Authority
having jurisdiction over such transaction, if required by an applicable statute,
regulation, order, judgment or decree.  Borrower represents, warrants and
covenants to Agent and the Lenders that Borrower and its Subsidiaries do not
intend to and shall not, without the prior written consent (if required) of the
"Office of Export Administration of the U.S. Department of Commerce",
Washington, D.C. 20230, transmit or ship any software products or modifications
thereto or products thereof, directly or indirectly to the Peoples Republic of
China or to any group Q, S, V, Y or Z country specified in Section 770 of the
Export Administration Regulations or any Supplements thereto issued by the U.S.

     5.14  No Threatened Insolvency.  Any Advance or Facility Letter of Credit
requested by Borrower or extended by Lenders or Issuer to or on behalf of
Borrower under this Agreement does not currently and to Borrower's best
knowledge will not in the future render Borrower insolvent.  Neither Borrower
nor any of Borrower's Material Subsidiaries are contemplating either the filing
of a petition under the Bankruptcy Code, or any other or similar law of any
Governmental Authority involving insolvency, or liquidation of all or a major
portion of their property.  No Person has filed or to Borrower's best knowledge
is contemplating filing any petition under any such law against Borrower or its
Material Subsidiaries.  Borrower and, to Borrower's best knowledge each of its

                                       38
<PAGE>
 
Material Subsidiaries, are now and at all times hereafter until and including
the date upon which all Obligations are indefeasibly repaid in full to Agent,
Issuer and the Lenders, solvent and generally paying their debts as they mature.
Borrower has capital sufficient to carry on its business and transactions and
all business and transactions in which it is about to engage.  Borrower now owns
and shall at all times during the term of this Agreement own property which, at
a fair valuation, is greater than the sum of its debts.
 
     5.15  Tax Returns.  To the best of its knowledge, Borrower itself has filed
and, each of its Material Subsidiaries has filed, on a timely basis all federal,
state, county and local income, excise, withholding, value added, property,
sales, use, franchise or other tax returns, declarations or reports which any
state, local, municipal, or federal authority of any Governmental Authority
required Borrower or its Material Subsidiaries to file on or before the
Effective Date.  All such tax returns, declarations and reports of Borrower, and
to Borrower's best knowledge its Material Subsidiaries, were true and correct,
and accurately reflected all taxable income and tax liabilities of Borrower and,
to Borrower's best knowledge its Material Subsidiaries, for all periods such
reports covered.  Borrower and to Borrower's best knowledge its Material
Subsidiaries have paid all taxes, interest and penalties, (if any), which became
due pursuant to such returns or pursuant to any assessment which has become
payable, except where payment is being contested in good faith and adequate
reserves have been provided on the Borrower's or such Material Subsidiary's
books and records.
 
     5.16  Financial Statements. Borrower has provided Agent and the Lenders 
with unaudited financial statements prepared by Borrower's management, which
cover the nine (9) month period ended September 30, 1998 (the "Unaudited
Financials"). The Unaudited Financials and all other financial information,
statements, warranties, projections, balance sheets, cash flow statements and
reports which Borrower provides to Agent and the Lenders shall be referred to
collectively in this Agreement as the "Financial Statements". The Financial
Statements which Borrower has delivered or will deliver to Agent and the Lenders
in the future will fully and fairly present the financial condition of Borrower
and its Subsidiaries, and the results of their business operations for the
respective periods indicated in such Financial Statements. The Financial
Statements were prepared in conformity with GAAP and are on a consolidated basis
with all of Borrower's Subsidiaries.
 
     5.17  Undisclosed Liabilities. The most recent ending date of the Unaudited
Financials shall be referred to in this Agreement as the "Balance Sheet Date".
Borrower and its Material Subsidiaries have no debts or liabilities of any type
or nature, whether accrued, absolute or contingent, determined or undetermined,
whether due or to become due (including without limitation unasserted claims
whether known or unknown, liabilities for taxes of any type, penalties, fees or
interest) other than those reflected in the Unaudited Financials dated as of the
Balance Sheet Date, those liabilities incurred in the ordinary course of
business since the Balance Sheet Date, and those liabilities which could not
have a Material Adverse Effect.  Neither Borrower nor any Material Subsidiary
have incurred any liability or debt which has or to Borrower's best knowledge
will have a Material Adverse Effect.  Except as identified on attached and
incorporated Schedule

                                       39
<PAGE>
 
5.17, since the Balance Sheet Date, neither Borrower nor its Material
Subsidiaries have experienced any Material Adverse Effect, and have not incurred
any material or unusual forward or long-term commitments. No fact or condition
exists, is contemplated or is to Borrower's best knowledge threatened which
might reasonably be expected to cause any such material adverse change in the
future.
 
     5.18  COBRA.  Except as would not be material: (i) Borrower and each
Material Subsidiary to which COBRA (as hereinafter defined) is applicable, has
provided each of their former employees with the right to continue his or her
respective insurance program with Borrower or applicable Material Subsidiary, in
compliance with all relevant provisions of the Code, as modified by the
Consolidated Omnibus Budget Reconciliation Act of 1985 ("COBRA"), including all
amendments to COBRA as contained in the Tax Reform Act of 1986, or any
subsequent legislation, (ii) there are no commitments, whether contractual in
nature or based upon any representation, warranty or other undertaking of
Borrower or such Material Subsidiary, which would preclude Borrower or such
Material Subsidiary from increasing the cost charged to individuals for
participating in any continuing medical benefit coverage, or (iii) except for
COBRA or as may be required under any state continuation coverage laws, Borrower
and such Material Subsidiaries have not established any employee benefit plan
which constitutes a "welfare benefit plan" within the meaning of Section 3(l) of
ERISA, providing for continuing benefits or coverage for any participant or
beneficiary of a participant after such participant's termination of employment
with Borrower or such Material Subsidiary.
 
     5.19  Intellectual Property.  Borrower directly or indirectly owns, is
licensed or otherwise possesses legally enforceable rights to use, all patents,
trademarks, trade names, service marks, copyrights and any applications
therefore, computer software products, and tangible or intangible property
information or material (excluding packaged commercially available software
programs generally available to the public which have been licensed to Borrower
or a Subsidiary pursuant to end-user licenses) ("Intellectual Property") that
are material to the business of Borrower and its Subsidiaries as currently
conducted by them.  Except as provided on Schedule 5.19, there is no claim
pending or, to Borrower's best knowledge, threatened, against Borrower or a
Subsidiary with respect to any alleged infringement of any trademark, service
mark, trade name, copyright, patent or trade secret owned by another person that
could reasonably be expected to have a Material Adverse Effect.  Except as
provided on Schedule 5.19, there is no claim or action pending or to Borrower's
best knowledge threatened concerning any Intellectual Property.
 
     5.20  ERISA.  As of the Effective Date, all Plans satisfy all minimum
funding standards of Section 302 of ERISA and Section 412 of the Code and no
material Reportable Event or material Termination Event exists concerning any
such Plan of Borrower or any member of Borrower's ERISA Controlled Group.
Neither Borrower nor any member of Borrower's ERISA Controlled Group has
incurred, or expects to incur, any withdrawal liability under Section 4201 of
ERISA to any Multiemployer Plan.
 
     5.21  Subsidiaries.  Schedule 5.21 hereto contains an accurate list of all
Subsidiaries of the Borrower as of the Effective Date, setting forth their
respective

stock owned by the Borrower or the other Subsidiaries. All of the issued and

authorized and issued and are fully paid and non-assessable, to the extent these
terms have local meanings substantially the same as their meanings under the law
chosen by the parties as governing this Agreement.

due provided, however, that it shall not constitute a default hereunder if the
Borrower or Material Subsidiary is contesting such default by appropriate
proceedings diligently conducted and the holder or holders have not commenced
suit or taken an action to foreclose on, or otherwise attach, any property of
the Borrower or such Material Subsidiary.

to bankruptcy, insolvency or reorganization or relief of debtors or fail to file
an answer or other pleading denying the material allegations of any such
proceeding filed against it, (v) take any corporate action to authorize or
effect any of the foregoing actions set forth in this Section 8.6 or (vi) fail
to contest in good faith any appointment or proceeding described in Section 8.7.

     8.7  Without the application, approval or consent of the Borrower or any of
its Material Subsidiaries, a receiver, trustee, examiner, liquidator or similar
official shall be appointed for the Borrower or any of its Material Subsidiaries
or any Substantial Portion of its or their Property, or a proceeding described
in Section 8.6(iv) shall be instituted against the Borrower or any of its
Material Subsidiaries and such appointment continues undischarged or such
proceeding continues undismissed or unstayed for a period of 60 consecutive
days.

     8.8  Any court, government or governmental agency shall condemn, seize or

twelve-month period ending with the month in which any such Condemnation occurs,
constitutes a Substantial Portion.

     8.9  The Borrower or any of its Subsidiaries shall fail within 30 days to

     8.11  The Borrower or any of its Subsidiaries shall be the subject of any
proceeding or investigation pertaining to the release by the Borrower or any of
its Subsidiaries, or any other Person of any toxic or hazardous waste or
substance into the environment, or any violation of any federal, state or local
environmental, health or safety law or regulation, which, in either case, could
reasonably be expected to have a Material Adverse Effect.

     8.12  Any Guaranty shall fail to remain in full force or effect or any
action shall be taken to discontinue or to assert the invalidity or
unenforceability of any Guaranty, or any Guarantor shall fail to comply with any
of the terms or provisions of any Guaranty to which it is a party, or any
Guarantor denies that it has any further liability under any Guaranty to which
it is a party, or gives notice to such effect.

     8.13  Any event or condition shall occur or exist with respect to the

                                   ARTICLE IX

                 ACCELERATION, WAIVERS, AMENDMENTS AND REMEDIES
                 ----------------------------------------------

     9.1  Acceleration.

     (a) If any Default described in Section 8.6 or 8.7 occurs, (i) the
obligations of the Lenders to make Loans hereunder and the obligation of the
Issuer to issue Facility Letters of Credit shall automatically terminate and the
Obligations shall immediately become due and payable without presentment,
demand, protest or notice of any kind, all of which the Borrower hereby
expressly waives and without any election or action on the part of the Agent or
any Lender and (ii) the Borrower will be and become thereby unconditionally
obligated, without the need for demand or the necessity of any act or evidence,
to deliver to the Agent, at its address specified pursuant to Article XIV, for
deposit into the Letter of Credit Collateral Account, an amount (the "Collateral
Shortfall Amount") equal to the excess, if any, of

     (A) 100% of the sum of the aggregate maximum amount remaining available to

                                       54
<PAGE>
 
be drawn under the Facility Letters of Credit (assuming compliance with all
conditions for drawing thereunder) issued by the Issuer and outstanding as of
such time, minus

     (B) the amount on deposit in the Letter of Credit Collateral Account at
such time that is free and clear of all rights and claims of third parties and
that has not been applied by the Lenders against the Obligations.

     (b) If any Default occurs and is continuing (other than a Default described
in Section 8.6 or 8.7), (i) the Required Lenders may terminate or suspend the
obligations of the Lenders to make Loans and the obligation of the Issuer to
issue Facility Letters of Credit hereunder, or declare the Obligations to be due
and payable, or both, whereupon the Obligations shall become immediately due and
payable, without presentment, demand, protest or notice of any kind, all of
which the Borrower hereby expressly waives and (ii) the Required Lenders may,
upon notice delivered to the Borrower and in addition to the continuing right to
demand payment of all amounts payable under this Agreement, make demand on the
Borrower to deliver (and the Borrower will, forthwith upon demand by the
Required Lenders and without necessity of further act or evidence, be and become
thereby unconditionally obligated to deliver), to the Agent, at its address
specified pursuant to Article XIV, for deposit into the Letter of Credit
Collateral Account an amount equal to the Collateral Shortfall Amount.

     (c) If at any time while any Default is continuing or after the Commitments
of the Lenders have been terminated, the Agent determines that the Collateral
Shortfall Amount at such time is greater than zero, the Agent may make demand on
the Borrower to deliver (and the Borrower will, forthwith upon demand by the
Agent and without necessity of further act or evidence, be and become thereby
unconditionally obligated to deliver), to the Agent as additional funds to be
deposited and held in the Letter of Credit Collateral Account an amount equal to
such Collateral Shortfall Amount at such time.

     (d) The Agent may at any time or from time to time after funds are
deposited in the Letter of Credit Collateral Account, apply such funds to the
payment of the Obligations and any other amounts as shall from time to time have
become due and payable by the Borrower to the Lenders under the Loan Documents.

     (e) Neither the Borrower nor any Person claiming on behalf of or through
the Borrower shall have any right to withdraw any of the funds held in the
Letter of Credit Collateral Account.  After all of the Obligations have been
indefeasibly paid in full, any funds remaining in the Letter of Credit
Collateral Account shall be returned by the Agent to the Borrower or paid to
whoever may be legally entitled thereto at such time.

     (f) The Agent shall exercise reasonable care in the custody and
preservation of any funds held in the Letter of Credit Collateral Account and
shall be deemed to have exercised such care if such funds are accorded treatment
substantially equivalent to that which the Agent accords its own property, it
being understood that the Agent shall not have any responsibility for taking any
necessary steps to preserve rights against any Persons with respect to any such
funds.

                                       55

     If, within 15 days after acceleration of the maturity of the Obligations or
termination of the obligations of the Lenders to make Loans hereunder and the
obligation of the Issuer to issue Facility Letters of Credit hereunder as a
result of any Default (other than any Default as described in Section 8.6 or 8.7
with respect to the Borrower) and before any judgment or decree for the payment
of the Obligations due shall have been obtained or entered, the Required Lenders
(in their sole discretion) shall so direct, the Agent shall, by notice to the
Borrower, rescind and annul such acceleration and/or termination.

     9.2  Amendments. Subject to the provisions of this Article IX, the Required
Lenders (or the Agent with the consent in writing of the Required Lenders) and
the Borrower may enter into agreements supplemental hereto for the purpose of
adding or modifying any provisions to the Loan Documents or changing in any
manner the rights of the Lenders or the Borrower hereunder or waiving any
Default hereunder; provided, however, that notwithstanding anything to the
contrary contained herein, no amendment, modification, change or waiver shall be
effective without consent of all the Lenders to:

          (i)    extend the maturity of the principal of, or interest on, any
                 Note or of any of the other Obligations;
          (ii)   increase or forgive the principal amount of any Note or of any
                 of the other Obligations or decrease the rate of interest
                 thereon;
          (iii)  change the date of payment of principal of, or interest on, any
                 Note or of any of the other Obligations;
          (iv)   change the amount of the Commitment of any Lender (except for a
                 ratable decrease in the Commitments of all Lenders);
          (v)    change the method of calculation utilized in connection with
                 the computation of interest and fees;
          (vi)   change the manner of pro rata application by the Agent of
                 payments made by the Borrower, or any other payments required
                 hereunder or under the other Loan Documents;
          (vii)  release any Guarantor;
          (viii) modify this Section or the definition of "Required Lenders";
                 and
          (ix)   permit the Borrower to assign its rights under this Agreement.

No amendment of any provision of this Agreement relating to the Agent shall be
effective without the written consent of the Agent. The Agent may waive payment
of the fee required under Section 13.3.2 without obtaining the consent of any
other party to this Agreement.

     9.3  Preservation of Rights. No delay or omission of the Lenders or the
Agent to exercise any right under the Loan Documents shall impair such right or
be construed to be a waiver of any Default or an acquiescence therein, and the
making of a Loan or the issuance of a Facility Letter of Credit notwithstanding
the existence of a Default or the inability of the Borrower to satisfy the
conditions precedent to making such Loan or issuing such Facility Letter of
Credit shall not constitute any waiver or acquiescence. Any

                                       56
<PAGE>
 
single or partial exercise of any such right shall not preclude other or
further exercise thereof or the exercise of any other right, and no waiver,
amendment or other variation of the terms, conditions or provisions of the Loan
Documents whatsoever shall be valid unless in writing signed by the Lenders
required pursuant to Section 9.2, and then only to the extent in such writing
specifically set forth. All remedies contained in the Loan Documents or by law
afforded shall be cumulative and all shall be available to the Agent, the
Issuer, and the Lenders until the Obligations have been paid in full.


                                   ARTICLE X

                               GENERAL PROVISIONS
                               ------------------

     10.1 Survival of Representations.  All representations and warranties of
the Borrower contained in this Agreement shall survive delivery of the Notes and
the making of the Loans and the issuance of the Facility Letters of Credit
herein contemplated.

     10.2 Governmental Regulation.  Anything contained in this Agreement to the
contrary notwithstanding, no Lender shall be obligated to extend credit to the
Borrower in violation of any limitation or prohibition provided by any
applicable statute or regulation.

     10.3 Taxes.  Any taxes (excluding federal income taxes on the overall net
income of any Lender) or other similar assessments or charges made by any
governmental or revenue authority in respect of the Loan Documents shall be paid
by the Borrower, together with interest and penalties, if any.

     10.4 Headings.  Section headings in the Loan Documents are for convenience
of reference only, and shall not govern the interpretation of any of the
provisions of the Loan Documents.

     10.5 Entire Agreement.  The Loan Documents embody the entire agreement and
understanding among the Borrower, the Agent, the Issuer and the Lenders and
supersede all prior agreements and understandings among the Borrower, the Agent,
the Issuer and the Lenders relating to the subject matter thereof other than the
fee letter described in Section 11.14.

     10.6 Several Obligations; Benefits of this Agreement.  The respective
obligations of the Lenders hereunder are several and not joint and no Lender
shall be the partner or agent of any other (except to the extent to which the
Agent is authorized to act as such). The failure of any Lender to perform any of
its obligations hereunder shall not relieve any other Lender from any of its
obligations hereunder. This Agreement shall not be construed so as to confer any
right or benefit upon any Person other than the parties to this Agreement and
their respective successors and assigns.

     10.7 Expenses; Indemnification.  The Borrower shall reimburse the Agent for
any
 
                                       57
<PAGE>
 
costs, internal charges and out-of-pocket expenses (including reasonable
attorneys' fees) paid or incurred by the Agent in connection with the
preparation, negotiation, execution, delivery, review, amendment, modification,
and administration of the Loan Documents, provided that Borrower shall not be
obligated to reimburse the Agent for legal fees in connection with the
preparation and execution of the Loan Documents for any amounts in excess of
$15,000. The Borrower also agrees to reimburse the Agent and the Lenders for any
costs and out-of-pocket expenses (including reasonable attorneys' fees and time
charges of attorneys for the Agent and the Lenders, which attorneys may be
employees of the Agent or the Lenders) paid or incurred by the Agent or any
Lender in connection with the collection and enforcement of the Loan Documents.
The Borrower further agrees to indemnify the Agent and each Lender, its
directors, officers and employees against all losses, claims, damages,
penalties, judgments, liabilities and expenses (including, without limitation,
all expenses of litigation or preparation therefor whether or not the Agent or
any Lender is a party thereto) which any of them may pay or incur arising out of
or relating to this Agreement, the other Loan Documents, the transactions
contemplated hereby or the direct or indirect application or proposed
application of the proceeds of any Loan or Facility Letter of Credit hereunder
except to the extent that they are determined by a court of competent
jurisdiction in a final and non-appealable order to have directly resulted from
the negligence, gross negligence, or willful misconduct of the party seeking
indemnification. The obligations of the Borrower under this Section shall
survive the termination of this Agreement.

     10.8   Numbers of Documents. All statements, notices, closing documents,
and requests hereunder shall be furnished to the Agent with sufficient
counterparts so that the Agent may furnish one to each of the Lenders.

     10.9   Accounting.  Except as provided to the contrary herein, all
accounting terms used herein shall be interpreted and all accounting
determinations hereunder shall be made in accordance with GAAP, except that any
calculation or determination which is to be made on a consolidated basis shall
be made for the Borrower and all its Subsidiaries, including those Subsidiaries,
if any, which are unconsolidated on the Borrower's audited financial statements.

     10.10  Severability of Provisions.  Any provision in any Loan Document that
is held to be inoperative, unenforceable, or invalid in any jurisdiction shall,
as to that jurisdiction, be inoperative, unenforceable, or invalid without
affecting the remaining provisions in that jurisdiction or the operation,
enforceability, or validity of that provision in any other jurisdiction, and to
this end the provisions of all Loan Documents are declared to be severable.

     10.11  Nonliability of Lenders.  The relationship between the Borrower, the
Lenders, the Issuer, and the Agent shall be solely that of borrower, lender and
letter of credit issuer. Neither the Agent, the Issuer, nor any Lender shall
have any fiduciary responsibilities to the Borrower. Neither the Agent, the
Issuer, nor any Lender undertakes any responsibility to the Borrower to review
or inform the Borrower of any matter in connection with any phase of the
Borrower's business or operations. The Borrower
 
                                       58
<PAGE>
 
agrees that neither the Agent, the Issuer, nor any Lender shall have liability
to the Borrower (whether sounding in tort, contract or otherwise) for losses
suffered by the Borrower in connection with, arising out of, or in any way
related to, the transactions contemplated and the relationship established by
the Loan Documents, or any act, omission or event occurring in connection
therewith, unless it is determined by a court of competent jurisdiction in a
final and non-appealable order that such losses resulted from the gross
negligence or willful misconduct of the party from which recovery is sought.
Neither the Agent, the Issuer, nor any Lender shall have any liability with
respect to, and the Borrower hereby waives, releases and agrees not to sue for,
any special, indirect or consequential damages suffered by the Borrower in
connection with, arising out of, or in any way related to the Loan Documents or
the transactions contemplated thereby.

     10.12  Confidentiality.  The Agent, the Issuer, and each Lender agree to
hold any confidential information which it may receive from the Borrower or any
Subsidiary pursuant to this Agreement in confidence, except for disclosure (i)
to its Affiliates and to other Lenders and their respective Affiliates, (ii) to
legal counsel, accountants, and other professional advisors to that Lender or to
a Transferee, (iii) to regulatory officials, (iv) to any Person as requested
pursuant to or as required by law, regulation, or legal process, (v) to any
Person in connection with any legal proceeding to which that Lender is a party,
and (vi) permitted by Section 13.4.


                                   ARTICLE XI

                                   THE AGENT
                                   ---------

     11.1   Appointment; Nature of Relationship.  American National Bank and
Trust Company of Chicago is hereby appointed by the Lenders as the Agent
hereunder and under each other Loan Document, and each of the Lenders
irrevocably authorizes the Agent to act as the contractual representative of
such Lender with the rights and duties expressly set forth herein and in the
other Loan Documents. The Agent agrees to act as such contractual representative
upon the express conditions contained in this Article XI. Notwithstanding the
use of the defined term "Agent," it is expressly understood and agreed that the
Agent shall not have any fiduciary responsibilities to any Lender by reason of
this Agreement or any other Loan Document and that the Agent is merely acting as
the representative of the Lenders with only those duties as are expressly set
forth in this Agreement and the other Loan Documents. In its capacity as the
Lenders' contractual representative, the Agent (i) does not hereby assume any
fiduciary duties to any of the Lenders, (ii) is a "representative" of the
Lenders within the meaning of Section 9-105 of the Uniform Commercial Code and
(iii) is acting as an independent contractor, the rights and duties of which are
limited to those expressly set forth in this Agreement and the other Loan
Documents. Each of the Lenders hereby agrees to assert no claim against the
Agent on any agency theory or any other theory of liability for breach of
fiduciary duty, all of which claims each Lender hereby waives.

                                       59
<PAGE>
 
     11.2   Powers.  The Agent shall have and may exercise such powers under the
Loan Documents as are specifically delegated to the Agent by the terms of each
thereof, together with such powers as are reasonably incidental thereto. The
Agent shall have no implied duties to the Lenders, or any obligation to the
Lenders to take any action thereunder except any action specifically provided by
the Loan Documents to be taken by the Agent.

     11.3   General Immunity.  Neither the Agent nor any of its directors,
officers, agents or employees shall be liable to the Borrower, the Lenders or
any Lender for any action taken or omitted to be taken by it or them hereunder
or under any other Loan Document or in connection herewith or therewith except
for its or their own gross negligence or willful misconduct.

     11.4   No Responsibility for Loans, Recitals, etc. Neither the Agent nor
any of its directors, officers, agents or employees shall be responsible for or
have any duty to ascertain, inquire into, or verify (i) any statement, warranty
or representation made in connection with any Loan Document or any borrowing
hereunder; (ii) the performance or observance of any of the covenants or
agreements of any obligor under any Loan Document, including, without
limitation, any agreement by an obligor to furnish information directly to each
Lender; (iii) the satisfaction of any condition specified in Article IV, except
receipt of items required to be delivered to the Agent; (iv) the validity,
enforceability, effectiveness, sufficiency or genuineness of any Loan Document
or any other instrument or writing furnished in connection therewith; or (v) the
value, sufficiency, creation, perfection or priority of any interest in any
collateral security.

     11.5   Action on Instructions of Lenders.  The Agent shall in all cases be
fully protected in acting, or in refraining from acting, hereunder and under any
other Loan Document in accordance with written instructions signed by the
Required Lenders (or all the Lenders, if required hereunder), and such
instructions and any action taken or failure to act pursuant thereto shall be
binding on all of the Lenders and on all holders of Notes. The Lenders hereby
acknowledge that the Agent shall be under no duty to take any discretionary
action permitted to be taken by it pursuant to the provisions of this Agreement
or any other Loan Document unless it shall be requested in writing to do so by
the Required Lenders. The Agent shall be fully justified in failing or refusing
to take any action hereunder and under any other Loan Document unless it shall
first be indemnified to its satisfaction by the Lenders pro rata against any and
all liability, cost and expense that it may incur by reason of taking or
continuing to take any such action.

     11.6   Employment of Agents and Counsel.  The Agent may execute any of its
duties as Agent hereunder and under any other Loan Document by or through
employees, agents, and attorneys-in-fact and shall not be answerable to the
Lenders, except as to money or securities received by it or its authorized
agents, for the default or misconduct of any such agents or attorneys-in-fact
selected by it with reasonable care. The Agent shall be entitled to advice of
counsel concerning all matters pertaining to the agency hereby created and its
duties hereunder and under any other Loan Document.

                                       60
<PAGE>
 
     11.7   Reliance on Documents; Counsel.  The Agent shall be entitled to rely
upon any Note, notice, consent, certificate, affidavit, letter, telegram,
statement, paper or document believed by it to be genuine and correct and to
have been signed or sent by the proper person or persons, and, in respect to
legal matters, upon the opinion of counsel selected by the Agent, which counsel
may be an employee of the Agent.

     11.8   Agent's Reimbursement and Indemnification.  The Lenders agree to
reimburse and indemnify the Agent ratably in proportion to their respective
Commitments (or, if the Commitments have been terminated, in proportion to their
Commitments immediately prior to such termination) (i) for any amounts not
reimbursed by the Borrower for which the Agent is entitled to reimbursement by
the Borrower under the Loan Documents, (ii) for any other expenses incurred by
the Agent on behalf of the Lenders and not reimbursed by the Borrower under the
Loan Documents, in connection with the preparation, execution, delivery,
administration and enforcement of the Loan Documents and (iii) for any
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind and nature whatsoever which may be
imposed on, incurred by or asserted against the Agent in any way relating to or
arising out of the Loan Documents or any other document delivered in connection
therewith or the transactions contemplated thereby, or the enforcement of any of
the terms thereof or of any such other documents, provided that no Lender shall
be liable for any of the foregoing to the extent they arise from the gross
negligence or willful misconduct of the Agent. The obligations of the Lenders
under this Section 11.8 shall survive payment of the Obligations and termination
of this Agreement.

     11.9   Notice of Default. The Agent shall not be deemed to have knowledge
or notice of the occurrence of any Default or Unmatured Default hereunder unless
the Agent has received written notice from a Lender or the Borrower referring to
this Agreement describing such Default or Unmatured Default and stating that
such notice is a "notice of default". In the event that the Agent receives such
a notice, the Agent shall give prompt notice thereof to the Lenders.

     11.10  Rights as a Lender.  In the event the Agent is a Lender or the
Issuer, the Agent shall have the same rights and powers hereunder and under any
other Loan Document as any Lender or Issuer and may exercise the same as though
it were not the Agent, and the term "Lender", "Lenders" or "Issuer" shall, at
any time when the Agent is a Lender or Issuer, unless the context otherwise
indicates, include the Agent in its individual capacity. The Agent may accept
deposits from, lend money to, and generally engage in any kind of trust, debt,
equity or other transaction, in addition to those contemplated by this Agreement
or any other Loan Document, with the Borrower or any of its Subsidiaries in
which the Borrower or such Subsidiary is not restricted hereby from engaging
with any other Person. The Agent, in its individual capacity, is not obligated
to remain a Lender or the Issuer.

     11.11  Lender Credit Decision.  Each Lender acknowledges that it has,
independently and without reliance upon the Agent or any other Lender and based
on the financial statements prepared by the Borrower and such other documents
and information
            
                                      61
<PAGE>
 
as it has deemed appropriate, made its own credit analysis and decision to enter
into this Agreement and the other Loan Documents. Each Lender also acknowledges
that it will, independently and without reliance upon the Agent or any other
Lender and based on such documents and information as it shall deem appropriate
at the time, continue to make its own credit decisions in taking or not taking
action under this Agreement and the other Loan Documents.

     11.12  Information.  The Agent shall promptly deliver to the Lenders
copies of all financial statements, written reports and other written
information delivered by the Borrower to the Agent in compliance with the terms
of this Agreement and any written requests by the Borrower for amendments or
waivers to the Agreement. The Agent agrees that upon receipt by it of a written
request from a Lender that such Lender wants information from the Borrower
pursuant to Section 6.3.5(E) and Section 6.3.7 and specifying the information it
wants, the Agent shall promptly request such information from the Borrower and
will cooperate with the Lender to obtain the information desired by such Lender.
The Agent shall have no responsibility for the timeliness, sufficiency, accuracy
or completeness of any information supplied by the Borrower or for any
interpretation or use thereof by the Lender. Agent's sole responsibility
hereunder shall be to request the Borrower to provide the information.

     11.13  Successor Agent.  The Agent may resign at any time by giving written
notice thereof to the Lenders and the Borrower, such resignation to be effective
upon the appointment of a successor Agent or, if no successor Agent has been
appointed, forty-five days after the retiring Agent gives notice of its
intention to resign. The Agent may be removed at any time with or without cause
by written notice received by the Agent from the Required Lenders, such removal
to be effective on the date specified by the Required Lenders. Upon any such
resignation or removal, the Required Lenders shall have the right to appoint, on
behalf of the Borrower and the Lenders and with the consent of the Borrower, a
successor Agent. If no successor Agent shall have been so appointed by the
Required Lenders and consented to by the Borrower within thirty days after the
resigning Agent's giving notice of its intention to resign, then the resigning
Agent may appoint, on behalf of the Borrower and the Lenders, a successor Agent.
If the Agent has resigned or been removed and no successor Agent has been
appointed, the Lenders may perform all the duties of the Agent hereunder and the
Borrower shall make all payments in respect of the Obligations to the applicable
Lender and for all other purposes shall deal directly with the Lenders. No
successor Agent shall be deemed to be appointed hereunder until such successor
Agent has accepted the appointment. Any such successor Agent shall be a
commercial bank having capital and retained earnings of at least $750,000,000.
Upon the acceptance of any appointment as Agent hereunder by a successor Agent,
such successor Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the resigning or removed Agent. Upon
the effectiveness of the resignation or removal of the Agent, the resigning or
removed Agent shall be discharged from its duties and obligations hereunder and
under the Loan Documents. After the effectiveness of the resignation or removal
of an Agent, the provisions of this Article X shall continue in effect for the
benefit of such Agent in respect of any actions taken or omitted to be taken by
it while it was acting as the Agent hereunder and under

     11.14  Agent's Fee.  The Borrower agrees to pay to the Agent, for its own
account, the fees agreed to by the Borrower and the Agent pursuant to that
certain letter agreement dated April 4, 1997, as amended August 28, 1997, or as
otherwise agreed from time to time.


                                  ARTICLE XII

                            SETOFF; RATABLE PAYMENTS
                            ------------------------

     12.1   Setoff.  In addition to, and without limitation of, any rights of
the Lenders under applicable law, if the Borrower becomes insolvent, however
evidenced, or any Default occurs, any and all deposits (including all account
balances, whether provisional or final and whether or not collected or
available) and any other Indebtedness at any time held or owing by any Lender to
or for the credit or account of the Borrower may be offset and applied toward
the payment of the Obligations owing to such Lender, whether or not the
Obligations, or any part hereof, shall then be due.

     12.2   Ratable Payments.  If any Lender, whether by setoff or otherwise,
has payment made to it upon its Loans (other than payments received pursuant to
Section 3.1, 3.2 or 3.4) in a greater proportion than that received by any other
Lender, such Lender agrees, promptly upon demand, to purchase a portion of the
Loans held by the other Lenders so that after such purchase each Lender will
hold its ratable proportion of Loans. If any Lender, whether in connection with
setoff or amounts which might be subject to setoff or otherwise, receives
collateral or other protection for its Obligations or such amounts which may be
subject to setoff, such Lender agrees, promptly upon demand, to take such action
necessary such that all Lenders share in the benefits of such collateral ratably
in proportion to their Loans. In case any such payment is disturbed by legal
process, or otherwise, appropriate further adjustments shall be made.

     If an amount to be setoff is to be applied to Indebtedness of the Borrower
to a Lender, other than Indebtedness evidenced by any of the Notes held by such
Lender or a Facility Letter of Credit Obligation, such amount shall be applied
first to the Obligations and only after the Obligations are paid in full and
discharged shall it be applied to Indebtedness not evidenced by the Notes or
Facility Letter of Credit.

               BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS
               -------------------------------------------------

     13.1   Successors and Assigns.  The terms and provisions of the Loan
Documents

                                      63
<PAGE>
 
shall be binding upon and inure to the benefit of the Borrower and the Lenders
and their respective successors and assigns, except that (i) the Borrower shall
not have the right to assign its rights or obligations under the Loan Documents
and (ii) any assignment by any Lender must be made in compliance with Section
13.3. Notwithstanding clause (ii) of this Section, any Lender may at any time,
without the consent of the Borrower or the Agent, assign all or any portion of
its rights under this Agreement and its Notes to a Federal Reserve Bank;
provided, however, that no such assignment to a Federal Reserve Bank shall
release the transferor Lender from its obligations hereunder. The Agent may
treat the payee of any Note as the owner thereof for all purposes hereof unless
and until such payee complies with Section 13.3 in the case of an assignment
thereof or, in the case of any other transfer, a written notice of the transfer
is filed with the Agent. Any assignee or transferee of a Note agrees by
acceptance thereof to be bound by all the terms and provisions of the Loan
Documents. Any request, authority or consent of any Person, who at the time of
making such request or giving such authority or consent is the holder of any
Note, shall be conclusive and binding on any subsequent holder, transferee or
assignee of such Note or of any Note or Notes issued in exchange therefor.

     13.2   Participations.

            13.2.1  Permitted Participants; Effect.  Any Lender may, in the
ordinary course of its business and in accordance with applicable law, at any
time sell to one or more banks or other entities ("Participants") participating
interests in any Loan owing to such Lender, any Note held by such Lender, any
Commitment of such Lender or any other interest of such Lender under the Loan
Documents. In the event of any such sale by a Lender of participating interests
to a Participant, such Lender's obligations under the Loan Documents shall
remain unchanged, such Lender shall remain solely responsible to the other
parties hereto for the performance of such obligations, such Lender shall remain
the holder of any such Note for all purposes under the Loan Documents, all
amounts payable by the Borrower under this Agreement shall be determined as if
such Lender had not sold such participating interests, and the Borrower and the
Agent shall continue to deal solely and directly with such Lender in connection
with such Lender's rights and obligations under the Loan Documents. No
Participant shall be permitted to make any claims itself under Article III, but
may make claims through its applicable Lender, but only to the extent that the
facts and circumstances giving rise to such claims also apply to the applicable
Lender.

            13.2.2  Voting Rights.  Each Lender shall retain the sole right to
approve, without the consent of any Participant, any amendment, modification or
waiver of any provision of the Loan Documents other than any amendment,
modification or waiver with respect to any Loan, Facility Letter of Credit or
Commitment in which such Participant has an interest which forgives principal,
interest or fees or reduces the interest rate or fees payable with respect to
any such Loan, Facility Letter of Credit or Commitment, postpones any date fixed
for any regularly-scheduled payment of principal of, or interest or fees on, any
such Loan, Facility Letter of Credit or Commitment, releases any Guarantor of
any such Loan, Facility Letter of Credit or releases any substantial portion of
collateral, if any, securing any such Loan or Facility Letter of Credit.

                                       64
<PAGE>
 
            13.2.3  Benefit of Setoff.  The Borrower agrees that each
Participant shall be deemed to have the right of setoff provided in Section 12.1
in respect of its participating interest in amounts owing under the Loan
Documents to the same extent as if the amount of its participating interest were
owing directly to it as a Lender under the Loan Documents, provided that each
Lender shall retain the right of setoff provided in Section 12.1 with respect to
the amount of participating interests sold to each Participant. The Lenders
agree to share with each Participant, and each Participant, by exercising the
right of setoff provided in Section 12.1, agrees to share with each Lender, any
amount received pursuant to the exercise of its right of setoff, such amounts to
be shared in accordance with Section 12.2 as if each Participant were a Lender.

     13.3 Assignments.

            13.3.1  Permitted Assignments.  Any Lender may, in the ordinary
course of its business and in accordance with applicable law, at any time assign
to one or more banks or other entities ("Purchasers") all or any part of its
rights and obligations under the Loan Documents. Such assignment shall be
substantially in the form of Exhibit "D" hereto or in such other form as may be
agreed to by the parties thereto. The consent of the Borrower and the Agent
shall be required prior to an assignment becoming effective with respect to a
Purchaser which is not a Lender or with respect to a Purchaser who is an
Affiliate where said assignment immediately results in the imposition of
increased costs pursuant to Article III hereof; provided, however, that if a
Default has occurred and is continuing, the consent of the Borrower shall not be
required to any assignment. Such consent shall not be unreasonably withheld or
delayed.

            13.3.2  Effect; Effective Date.  Upon (i) delivery to the Agent of a
notice of assignment, substantially in the form attached as Exhibit "I" to
Exhibit "D" hereto (a "Notice of Assignment"), together with any consents
required by Section 13.3.1, and (ii) payment of a $4,000 fee to the Agent for
processing such assignment, such assignment shall become effective on the
effective date specified in such Notice of Assignment. The Notice of Assignment
shall contain a representation by the Purchaser to the effect that none of the
consideration used to make the purchase of the Commitment and Loans under the
applicable assignment agreement are "plan assets" as defined under ERISA and
that the rights and interests of the Purchaser in and under the Loan Documents
will not be "plan assets" under ERISA. On and after the effective date of such
assignment, such Purchaser shall for all purposes be a Lender party to this
Agreement and any other Loan Document executed by the Lenders and shall have all
the rights and obligations of a Lender under the Loan Documents, to the same
extent as if it were an original party hereto, and no further consent or action
by the Borrower, the Lenders or the Agent shall be required to release the
transferor Lender with respect to the percentage of the Aggregate Commitment and
Loans assigned to such Purchaser. Upon the consummation of any assignment to a
Purchaser pursuant to this Section 13.3.2, the transferor Lender, the Agent and
the Borrower shall make appropriate arrangements so that replacement Notes are
issued to such transferor Lender and new Notes or, as appropriate, replacement
Notes, are issued to such Purchaser, in each case in principal

                                       65
<PAGE>
 
amounts reflecting their Commitment, as adjusted pursuant to such assignment.

     13.4  Dissemination of Information.  The Borrower authorizes each Lender to
disclose to any Participant or Purchaser or any other Person acquiring an
interest in the Loan Documents by operation of law (each a "Transferee") and any
prospective Transferee any and all information in such Lender's possession
concerning the creditworthiness of the Borrower and its Subsidiaries; provided
that each Transferee and prospective Transferee agrees to be bound by Section
10.12 of this Agreement.

     13.5  Tax Treatment.  If any interest in any Loan Document is transferred 
to any Transferee which is organized under the laws of any jurisdiction other
than the United States or any State thereof, the transferor Lender shall cause
such Transferee, concurrently with the effectiveness of such transfer, to comply
with the provisions of Section 4.3.

     14.1  Notices.  Except as otherwise permitted by Section 2.13 with respect
to borrowing notices, all notices, requests and other communications to any

Borrower, the Issuer or the Agent, at its address or facsimile number set forth

its address or facsimile number set forth below its signature hereto or (z) in
the case of any party, such other address or facsimile number as such party may
hereafter specify for the purpose by notice to the Agent and the Borrower.  Each
such notice, request or other communication shall be effective (i) if given by
facsimile transmission, when transmitted to the facsimile number specified in
this Section and confirmation of receipt is received, (ii) if given by mail, 72
hours after such communication is deposited in the mails with first class
postage prepaid, addressed as aforesaid or (iii) if given by any other means,
when delivered at the address specified in this Section; provided that notices
to the Agent under Article II shall not be effective until received.

     14.2  Change of Address.  The Borrower, the Agent, the Issuer and any 
Lender may each change the address for service of notice upon it by a notice in
writing to the other parties hereto.

     15.1  Counterparts.  This Agreement may be executed in any number of
counterparts, all of which taken together shall constitute one agreement, and
any of the parties hereto may execute this Agreement by signing any such
counterpart.  This Agreement shall be effective when it has been executed by the
Borrower, the Agent and the Lenders and each party has notified the Agent by
telex or telephone, that it has taken such action.

     15.2  Amendment and Restatement.  This Agreement constitutes an amendment
and restatement of the Prior Credit Agreement, which Prior Credit Agreement is

however, that the Obligations governed by the Prior Credit Agreement shall
remain outstanding and in full force and effect and provided further that this
Agreement does not constitute a novation of such Obligations.

     16.1  CHOICE OF LAW.  THE LOAN DOCUMENTS (OTHER THAN THOSE CONTAINING A

COURT AND IRREVOCABLY WAIVES ANY OBJECTION IT MAY NOW OR HEREAFTER HAVE AS TO
THE VENUE OF ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN SUCH A COURT OR THAT
SUCH COURT IS AN INCONVENIENT FORUM.  NOTHING HEREIN SHALL LIMIT THE RIGHT OF
THE AGENT, THE ISSUER OR ANY LENDER TO BRING PROCEEDINGS AGAINST THE BORROWER IN
THE COURTS OF ANY OTHER JURISDICTION.  ANY JUDICIAL PROCEEDING BY THE BORROWER
AGAINST THE AGENT OR ANY LENDER OR ANY AFFILIATE OF THE AGENT, THE ISSUER, OR

$____________                                                  December 21, 1998


     PLATINUM technology, inc., a Delaware corporation (the "Borrower"),
promises to pay to the order of __________________________________ (the 
"Lender") the lesser of the principal sum of __________________ Dollars or the
aggregate unpaid principal amount of all Loans made by the Lender to the
Borrower pursuant to Article II of the Agreement (as hereinafter defined), in
immediately available funds at the main office of American National Bank and
Trust Company of Chicago in Chicago, Illinois, as Agent, together with interest
on the unpaid principal amount hereof at the rates and on the dates set forth in
the Agreement.  The Borrower shall pay the principal of and accrued and unpaid
interest on the Loans in full on the Facility Termination Date.

     The Lender shall, and is hereby authorized to, record on the schedule
attached hereto, or to otherwise record in accordance with its usual practice,
the date and amount of each Loan and the date and amount of each principal
payment hereunder.  Subject to the terms of the Agreement, the Borrower may
repay and reborrow at any time prior to the Facility Termination Date.

     This Note is one of the Notes issued pursuant to, and is entitled to the
benefits of, the Credit Agreement dated as of December 21, 1998, (which, as it
may be amended or modified and in effect from time to time, is herein called the
"Agreement"), among the Borrower, the lenders party thereto, including the
Lender, and American National Bank and Trust Company of Chicago, as Agent, to
which Agreement reference is hereby made for a statement of the terms and
conditions governing this Note, including the terms and conditions under which

                                                         __________, 19__

The Agent and the Lenders who are parties to the
Credit Agreement described below.

Gentlemen/Ladies:

     We are counsel for PLATINUM technology, inc. (the "Borrower"), and have
represented the Borrower in connection with its execution and delivery of a
Credit Agreement dated as of December 21, 1998 (the "Agreement") among the
Borrower, the Lenders named therein, and American National Bank and Trust
Company of Chicago, as Agent, and providing for Advances and Facility Letters of
Credit in an aggregate principal amount not exceeding $65,000,000 at any one
time outstanding.  All capitalized terms used in this opinion and not otherwise
defined herein shall have the meanings attributed to them in the Agreement.

     We have examined the Borrower's articles of incorporation, by-laws,
resolutions, the Loan Documents and such other matters of fact and law which we
deem necessary in order to render this opinion.  Based upon the foregoing, it is
our opinion that:

     l.   The Borrower and each Material Subsidiary are corporations duly
incorporated, validly existing and in good standing under the laws of their
states of incorporation and have all requisite authority to conduct their
business in each jurisdiction in which their business is conducted.

     2.   The execution and delivery of the Loan Documents by the Borrower and
the performance by the Borrower of the Obligations have been duly authorized by
all necessary corporate action and proceedings on the part of the Borrower and
will not:

          (a) require any consent of the Borrower's shareholders;

          (b) violate any law, rule, regulation, order, writ, judgment,
     injunction, decree or award binding on the Borrower or any of its Material
     Subsidiaries or the Borrower's or any Material Subsidiary's articles of
     incorporation or by-laws or any indenture, instrument or agreement binding
     upon the Borrower or any of its Subsidiaries; or

          (c) result in, or require, the creation or imposition of any Lien
     pursuant to the provisions of any indenture, instrument or agreement
     binding upon the Borrower or any of its Subsidiaries.

     3.   The Loan Documents have been duly executed and delivered by the
Borrower and constitute legal, valid and binding obligations of the Borrower
enforceable in 

                                     B-1
<PAGE>
 
accordance with their terms except to the extent the enforcement thereof may be
limited by bankruptcy, insolvency or similar laws affecting the enforcement of
creditors' rights generally and subject also to the availability of equitable
remedies if equitable remedies are sought.

     4.   There is no litigation or proceeding against the Borrower or any of
its Subsidiaries which, if adversely determined, could reasonably be expected to
have a Material Adverse Effect.

     5.   No approval, authorization, consent, adjudication or order of any
governmental authority, which has not been obtained by the Borrower or any of
its Subsidiaries, is required to be obtained by the Borrower or any of its
Material Subsidiaries in connection with the execution and delivery of the Loan
Documents, the borrowings under the Agreement, the issuance of any Facility
Letters of Credit or in connection with the payment by the Borrower of the
Obligations.

     6.   The Obligations constitute senior indebtedness which is entitled to 
the benefits of the subordination provisions of all outstanding Subordinated
Indebtedness.

     This opinion may be relied upon by the Agent, the Lenders and their
participants, assignees and other transferees.


                              Very truly yours,

                              ___________________________

                              ASSIGNMENT AGREEMENT

     This Assignment Agreement (this "Assignment Agreement") between
__________________________ (the "Assignor") and __________________ (the
"Assignee") is dated as of _________________, 19__.  The parties hereto agree as
follows:

     1.   PRELIMINARY STATEMENT.  The Assignor is a party to a Credit Agreement
(which, as it may be amended, modified, renewed or extended from time to time is
herein called the "Credit Agreement") described in Item 1 of Schedule 1 attached
hereto ("Schedule 1").  Capitalized terms used herein and not otherwise defined
herein shall have the meanings attributed to them in the Credit Agreement.

     2.   ASSIGNMENT AND ASSUMPTION.  The Assignor hereby sells and assigns to
the Assignee, and the Assignee hereby purchases and assumes from the Assignor,
an interest in and to the Assignor's rights and obligations under the Credit
Agreement such that after giving effect to such assignment the Assignee shall
have purchased pursuant to this Assignment Agreement the percentage interest
specified in Item 3 of Schedule 1 of all outstanding rights and obligations
under the Credit Agreement relating to the facilities listed in Item 3 of
Schedule 1 and the other Loan Documents.  The aggregate Commitment (or Loans and
participations in the Facility Letters of Credit, if the applicable Commitment
has been terminated) purchased by the Assignee hereunder is set forth in Item 4
of Schedule 1.

     3.   EFFECTIVE DATE.  The effective date of this Assignment Agreement (the
"Effective Date") shall be the later of the date specified in Item 5 of Schedule
1 or two Business Days (or such shorter period agreed to by the Agent) after a
Notice of Assignment substantially in the form of Exhibit "I" attached hereto
has been delivered to the Agent.  Such Notice of Assignment must include any
consents required to be delivered to the Agent by Section 13.3.1 of the Credit
Agreement.  In no event will the Effective Date occur if the payments required
to be made by the Assignee to the Assignor on the Effective Date under Sections
4 and 5 hereof are not made on the proposed Effective Date.  The Assignor will
notify the Assignee of the proposed Effective Date no later than the Business
Day prior to the proposed Effective Date.  As of the Effective Date, (i) the
Assignee shall have the rights and obligations of a Lender under the Loan
Documents with respect to the rights and obligations assigned to the Assignee
hereunder and (ii) the Assignor shall relinquish its rights and be released from
its corresponding obligations under the Loan Documents with respect to the
rights and obligations assigned to the Assignee hereunder.

     4.   PAYMENTS OBLIGATIONS.  On and after the Effective Date, the Assignee
shall be entitled to receive from the Agent all payments of principal,
reimbursement payments under Facility Letters of Credit, interest and fees with
respect to the interest assigned hereby.  The Assignee shall advance funds
directly to the Agent with respect to 

                                      D-1
<PAGE>
 
all Loans and reimbursement payments made on or after the Effective Date with
respect to the interest assigned hereby. In consideration for the sale and
assignment of Loans and participations in the Letters of Credit hereunder, (i)
the Assignee shall pay the Assignor, on the Effective Date, an amount equal to
the principal amount of the portion of all Floating Rate Loans assigned to the
Assignee hereunder and (ii) with respect to each Fixed Rate Loan made by the
Assignor and assigned to the Assignee hereunder which is outstanding on the
Effective Date, (a) on the last day of the Eurodollar Interest Period therefor
or (b) on such earlier date agreed to by the Assignor and the Assignee or (c) on
the date on which any such Fixed Rate Loan either becomes due (by acceleration
or otherwise) or is prepaid (the date as described in the foregoing clauses (a),
(b) or (c) being hereinafter referred to as the "Payment Date"), the Assignee
shall pay the Assignor an amount equal to the principal amount of the portion of
such Fixed Rate Loan assigned to the Assignee which is outstanding on the
Payment Date. If the Assignor and the Assignee agree that the Payment Date for
such Fixed Rate Loan shall be the Effective Date, they shall agree to the
interest rate applicable to the portion of such Loan assigned hereunder for the
period from the Effective Date to the end of the existing Eurodollar Interest
Period applicable to such Fixed Rate Loan (the "Agreed Interest Rate") and any
interest received by the Assignee in excess of the Agreed Interest Rate shall be
remitted to the Assignor. In the event interest for the period from the
Effective Date to but not including the Payment Date is not paid by the Borrower
with respect to any Fixed Rate Loan sold by the Assignor to the Assignee
hereunder, the Assignee shall pay to the Assignor interest for such period on
the portion of such Fixed Rate Loan sold by the Assignor to the Assignee
hereunder at the applicable rate provided by the Credit Agreement. In the event
a prepayment of any Fixed Rate Loan which is existing on the Payment Date and
assigned by the Assignor to the Assignee hereunder occurs after the Payment Date
but before the end of the Eurodollar Interest Period applicable to such Fixed
Rate Loan, the Assignee shall remit to the Assignor the excess of the prepayment
penalty paid with respect to the portion of such Fixed Rate Loan assigned to the
Assignee hereunder over the amount which would have been paid if such prepayment
penalty was calculated based on the Agreed Interest Rate. The Assignee will also
promptly remit to the Assignor (i) any principal payments received from the
Agent with respect to Fixed Rate Loans prior to the Payment Date and (ii) any
amounts of interest on Loans and fees and reimbursement payments received from
the Agent which relate to the portion of the Loans and Facility Letters of
Credit assigned to the Assignee hereunder for periods prior to the Effective
Date, in the case of Floating Rate Loans or fees, or the Payment Date, in the
case of Fixed Rate Loans, and not previously paid by the Assignee to the
Assignor.* In the event that either party hereto receives any payment to which
the other party hereto is entitled under this Assignment Agreement, then the
party receiving such amount shall promptly remit it to the other party hereto.

*Each Assignor may insert its standard payment provisions in lieu of the payment
terms included in this Exhibit.

     5.   FEES PAYABLE BY THE ASSIGNEE.  The Assignee shall pay to the Assignor
a fee on each day on which a payment of interest or fees is made under the
Credit Agreement with respect to the amounts assigned to the Assignee hereunder
(other 

                                      D-2
<PAGE>
 
than a payment of interest or commitment fees for the period prior to the
Effective Date or, in the case of Fixed Rate Loans, the Payment Date, which the
Assignee is obligated to deliver to the Assignor pursuant to Section 4 hereof).
The amount of such fee shall be the difference between (i) the interest or fee,
as applicable, paid with respect to the amounts assigned to the Assignee
hereunder and (ii) the interest or fee, as applicable, which would have been
paid with respect to the amounts assigned to the Assignee hereunder if each
interest rate was ___ of 1%  less than the interest rate paid by the Borrower or
if the [commitment fee/ Facility Letter of Credit fee] was ___ of 1% less than
the commitment fee paid by the Borrower, as applicable.  In addition, the
Assignee agrees to pay ___% of the recordation fee required to be paid to the
Agent in connection with this Assignment Agreement.

     6.   REPRESENTATIONS OF THE ASSIGNOR; LIMITATIONS ON THE ASSIGNOR'S
LIABILITY.  The Assignor represents and warrants that it is the legal and
beneficial owner of the interest being assigned by it hereunder and that such
interest is free and clear of any adverse claim created by the Assignor.  It is
understood and agreed that the assignment and assumption hereunder are made
without recourse to the Assignor and that the Assignor makes no other
representation or warranty of any kind to the Assignee.  Neither the Assignor
nor any of its officers, directors, employees, agents or attorneys shall be
responsible for (i) the due execution, legality, validity, enforceability,
genuineness, sufficiency or collectability of any Loan Document, including
without limitation, documents granting the Assignor and the other Lenders a
security interest in assets of the Borrower or any guarantor, (ii) any
representation, warranty or statement made in or in connection with any of the
Loan Documents, (iii) the financial condition or creditworthiness of the
Borrower or any guarantor, (iv) the performance of or compliance with any of the
terms or provisions of any of the Loan Documents, (v) inspecting any of the
Property, books or records of the Borrower, (vi) the validity, enforceability,
perfection, priority, condition, value or sufficiency of any collateral securing
or purporting to secure the Loans and the Facility Letters of Credit or (vii)
any mistake, error of judgment, or action taken or omitted to be taken in
connection with the Loans or the Loan Documents.

     7.   REPRESENTATIONS OF THE ASSIGNEE.  The Assignee (i) confirms that it
has received a copy of the Credit Agreement, together with copies of the
financial statements requested by the Assignee and such other documents and
information as it has deemed appropriate to make its own credit analysis and
decision to enter into this Assignment Agreement, (ii) agrees that it will,
independently and without reliance upon the Agent, the Assignor or any other
Lender and based on such documents and information at it shall deem appropriate
at the time, continue to make its own credit decisions in taking or not taking
action under the Loan Documents, (iii) appoints and authorizes the Agent to take
such action as agent on its behalf and to exercise such powers under the Loan
Documents as are delegated to the Agent by the terms thereof, together with such
powers as are reasonably incidental thereto, (iv) agrees that it will perform in
accordance with their terms all of the obligations which by the terms of the
Loan Documents are required to be performed by it as a Lender, (v) agrees that

From:     [NAME OF ASSIGNOR] (the "Assignor")

          [NAME OF ASSIGNEE] (the "Assignee")

     1.   We refer to that Credit Agreement (the "Credit Agreement") described
in Item 1 of Schedule 1 attached hereto ("Schedule 1").  Capitalized terms used
herein and not otherwise defined herein shall have the meanings attributed to
them in the Credit Agreement.

     2.   This Notice of Assignment (this "Notice") is given and delivered to
[the Borrower and] the Agent pursuant to Section [13.3.2] of the Credit
Agreement.

     3.   The Assignor and the Assignee have entered into an Assignment
Agreement, dated as of ___________, 19__ (the "Assignment"), pursuant to which,
among other things, the Assignor has sold, assigned, delegated and transferred
to the Assignee, and the Assignee has purchased, accepted and assumed from the
Assignor the percentage interest specified in Item 3 of Schedule 1 of all
outstandings, rights and obligations under the Credit Agreement relating to the
facilities listed in Item 3 of Schedule 1.  The Effective Date of the Assignment
shall be the later of the date specified in Item 5 of Schedule 1 or two Business
Days (or such shorter period as agreed to by the Agent) after this Notice of
Assignment and any consents and fees required by Sections 13.3.1 and 13.3.2 of
the Credit Agreement have been delivered to the Agent, provided that the
Effective Date shall not occur if any condition precedent agreed to by the
Assignor and the Assignee has not been satisfied.

     4.   The Assignor and the Assignee hereby give to the Borrower and the
Agent notice of the assignment and delegation referred to herein.  The Assignor
will confer with the Agent before the date specified in Item 5 of Schedule 1 to

<PAGE>
 
and will confer with the Agent to determine the Effective Date pursuant to
Section 3 hereof if it occurs thereafter. The Assignor shall notify the Agent if
the Assignment Agreement does not become effective on any proposed Effective

the Assignor and the Assignee. At the request of the Agent, the Assignor will
give the Agent written confirmation of the satisfaction of the conditions
precedent.

     5.   The Assignor or the Assignee shall pay to the Agent on or before the

     6.   If Notes are outstanding on the Effective Date, the Assignor and the
Assignee request and direct that the Agent prepare and cause the Borrower to
execute and deliver new Notes or, as appropriate, replacements notes, to the

agree to deliver to the Agent the original Note received by it from the Borrower
upon its receipt of a new Note in the appropriate amount.

     7.   The Assignee advises the Agent that notice and payment instructions
are set forth in the attachment to Schedule 1.

     8.   The Assignee hereby represents and warrants that none of the funds,
monies, assets or other consideration being used to make the purchase pursuant
to the Assignment are "plan assets" as defined under ERISA and that its rights,
benefits, and interests in and under the Loan Documents will not be "plan
assets" under ERISA.

     9.   The Assignee authorizes the Agent to act as its agent under the Loan
Documents in accordance with the terms thereof.  The Assignee acknowledges that
the Agent has no duty to supply information with respect to the Borrower or the
Loan Documents to the Assignee until the Assignee becomes a party to the Credit
Agreement.*

*May be eliminated if Assignee is a party to the Credit Agreement prior to the
Effective Date.

     This summarizes Platinum technology, inc.'s ("PTI") action on reorganizing
PTI into a holding company structure.  As shown on the attached chart, the new
organization will result in the current PTI becoming a holding company with no
operations.  The name "Platinum technology, inc." will be moved down to the
operating subsidiary level.  PTI will then have three new subsidiaries (one
first tier and two second tier):/1/

     The intellectual property ("IP") holding company -- this will be the first
          tier subsidiary which will hold all intellectual property and license
          it for use by the other subsidiaries;

     1.   The principal operating company -- this will be owned by the IP
          Holding Company and will own all of the domestic assets, employ the
          domestic operating personnel and conduct all the domestic business;

     The international holding company ("IHC") -- this will be owned by the IP
          Holding Company, will have exclusive foreign distribution rights to
          the firm's software and outbound international IP rights will be
          channeled through this company.

     The mechanics of the transaction in broad brush strokes are as follows:

I.   Create New Operating Company.
     ---------------------------- 

     Current PTI establishes a newly formed wholly owned Delaware corporation.
          At conclusion of the reorganization current PTI will be renamed so
          that the operating company is Platinum technology, inc.

     Current PTI assigns to the new operating sub all of PTI's operating assets,
          liabilities and contracts.  The non operating items retained by the
          current PTI will be cash, investments, stock in subsidiaries (foreign
          and domestic), convertible notes payable, and any outstanding debt
          under any credit agreement.  In return for this contribution, PTI
          would receive the stock of the newco, a promissory note payable from
          newco to PTI, and agreements for the operating company to use and
          exploit PTI's current intellectual property and develop all future
          intellectual property which in turn would be owned by the new
          intellectual property holding company.

     All domestic operations would then be conducted out of the new operating
          company.

II.  Create International Holding Company ("IHC").
     -------------------------------------------- 

     Current PTI also forms an international holding company which will be an
          off-shore entity organized in the Netherlands.

     When the IP Holding Company is formed (see III below), the IHC is
          contributed to the IP Holding Company and becomes a subsidiary of the
          IP Holding Company.  The IHC will then be granted an exclusive license
          from the IP Holding Company for distributing 

- - ------------------------
/1/ Additionally, the existing acquired subsidiaries would continue to exist and
    be transferred to and owned by the intellectual property holding company.
    New acquisitions in the future to be paid for in PTI stock would be done
    through new first tier subsidiaries which might later be dropped down and
    become wholly owned by the IP Holding Company.
<PAGE>
 
          PTI's intellectual property rights off-shore.

     The stock of all (or a vast majority of) existing foreign subsidiaries will
          also be transferred to the IHC.

     Any foreign subsidiaries that have development operations will contract
          directly with the IP Holding Company to develop future intellectual
          property for the account of the IP Holding Company.

III. Create IP Holding Company:
     ------------------------- 

     Current PTI forms a new Delaware corporation, the sole business of which
          will be to hold and license all of the PTI intellectual property.

     Current PTI will contribute all its intellectual property to the IP Holding
          Company and the stock of all the other subsidiaries (i.e., the new
          operating company, the new international holding company and other
          existing acquisition subsidiaries) in return for the stock of IP
          Holding Company and a note.  The new operating company and the other
          subsidiaries will then be subsidiaries of the IP Holding Company.

     The IP Holding Company licenses the intellectual property to the new
          operating company.  The new operating company also agrees to develop
          future intellectual property for the account of the IP Holding
          Company.

  Credit Agreement Issues
  -----------------------

     Each of the new operating company, the IHC and IP Holding Company would
          guaranty or become a co-obligor under PTI's Amended and Restated
          Credit Agreement with American National Bank and Trust Company of
          Chicago, as Agent, and the lenders party thereto (the "Credit
          Agreement"). In addition, each of Platinum Technology UK Limited,
          Platinum Technology GmbH, and each other foreign subsidiary which is
          or becomes a Material Subsidiary as defined in the Credit Agreement
          would guaranty PTI's obligations thereunder.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS



To Mastering, Inc.:

We have audited the consolidated balance sheet of Mastering, Inc. (formerly 
Eagle River Interactive, Inc.), a Delaware corporation, and subsidiaries as of 
December 31, 1997, and the related consolidated statements of operations, 
stockholders' equity (deficit) and cash flows for each of the two years in the 
period ended December 31, 1997, not presented separately herein. These financial
statements are the responsibility of the Company's management. Our 
responsibility is to express an opinion on these financial statements based on 
our audits.

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

In our opinion, the financial statements referred to above, not presented 
separately herein, present fairly, in all material respects, the consolidated 
financial position of Mastering, Inc. and subsidiaries as of December 31, 1997, 
and the consolidated results of their operations and their cash flows for each 
of the two years in the period ended December 31, 1997, in conformity with 
generally accepted accounting principles.

The Board of Directors

We have audited the accompanying consolidated balance sheet of Logic Works, Inc.

financial statement schedule II - valuation and qualifying accounts for the 
years ended December 31, 1997 and 1996. These financial statements and schedule 
are the responsibility of the Company's management. Our responsibility is to 
express an opinion on these financial statements and 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 consolidated financial position of Logic 
Works, Inc. and subsidiaries at December 31, 1997, and the consolidated results 
of their operations and their cash flow for the years ended December 31, 1997 
and 1996, in conformity with generally accepted accounting principles. Also, in 
our opinion, the related financial statement schedule, when considered in 
relation to the basic financial statements taken as a whole, presents fairly in 
all material respects the information set forth therein.
