PART I.

ITEM 1.  BUSINESS

GENERAL

       USDATA Corporation (the "Company"), is a global supplier of
component-based production software that is designed to help customers reduce
operating costs, shorten cycle times and improve product quality in their
manufacturing operations. The Company's software enables manufacturers to access
more accurate and timely information - whether they are on the plant-floor, in
the office, or around the globe. The Company's solutions span a wide range of
manufacturing processes, from monitoring equipment to tracking product flow, and
are designed to integrate seamlessly with customers' existing manufacturing and
business software. This combination of product breadth and ease of integration
is intended to provide a total plant solution that defines new levels of
manufacturing performance and gives customers a distinct competitive advantage.
Now in its 25th year, the Company has a strong global presence with more than
45,000 installs located in more than 60 countries throughout the world, 19
offices worldwide and a global network of distribution and support partners.

         The Company is committed to solving customer problems and increasing
productivity in the manufacturing and production environments through
technological innovation. The Company's products are noted for high performance,
ease-of-use and support of enterprise computing environments. The Company's
customers are in a wide variety of industries including; chemical, oil and gas,
food, beverage, automotive, aerospace, telecommunications, electronics,
transportation and other industries.

         The Company's family of software products, marketed under the names of
FactoryLink, Xfactory, Connector, Analysis and Smart Manager provide a powerful
set of software tools and applications designed for users who are technically
competent but who may not be experienced software programmers.

         In the latter part of 1999 the Company formed its new eMake division
which is focused on the "make" or production area of the manufacturing supply
chain. Through the eMake division, the Company intends to provide a suite of
Internet applications that will include a real-time production portal with
secure, online shop-floor visibility and an eBusiness trading market designed
specifically for manufacturers. The eMake division includes the operations of
Smart Shop Software Inc., an enterprise business solution subsidiary of the
Company with integrated accounting to shop floor processes for make-to-order
small and medium size manufacturers marketed as Smart Manager. The Smart Shop
Software unit includes the assets of Smart Shop Software, Inc. (Idaho), which
were acquired by the Company in mid-1999.

PRODUCTS AND SERVICES

OVERVIEW

         The Company develops, markets and supports component-based software
products for customers requiring enterprise-wide, open systems solutions for the
manufacturing and production markets. These software products provide customers
real-time component-based computer applications that provide interactive,
dynamic and graphical interfaces to manufacturing and production operations.
These applications collect, consolidate and communicate information about an
automated manufacturing process, typically drawn from complex operating sources
or from multiple sites throughout an enterprise, and enable the user to interact
with and control plant-wide processes. The real-time information provided by the
Company's products enables customers to reduce operating costs, improve product
quality and increase overall throughput and productivity.

         The Company's flagship software product, FactoryLink(R), is a
manufacturing process solution used to develop custom supervisory control and
data acquisition ("SCADA") and human machine interfaces ("HMI") for the
supervision and control of a broad range of automated processes. FactoryLink is
a real-time application server product that enables manufacturers to connect to
plant floor devices, consolidate and process data and communicate the data to
decision-makers throughout the manufacturing enterprise. FactoryLink gives
manufacturers the accurate and timely production information they need to make
effective decisions throughout the enterprise. FactoryLink, as the plant server,
is the centerpiece of a real-time data distribution architecture.

         In mid-1998, the Company introduced Xfactory(R), a manufacturing
execution solution ("MES") product which incorporates Microsoft's newest
technologies and is built on Microsoft's Distributed Internet Applications
("DNA") architecture. Xfactory enables manufacturing plants to more easily and
quickly automate their production processes and is the first visual object
modeling MES.

         In 1999, the Company introduced two new products: USDATA Connector,
which enables connectivity to higher level business systems and USDATA Analysis,
which provides real-time access to and analysis of a customer's information.


                                       2

         In conjunction with the purchase of Smart Shop Software, Inc. in mid
1999, the Company acquired the Smart Manager software product with integrated
accounting to shop floor processes for make-to-order small and medium size
manufacturers.

BACKGROUND AND MARKET DEMAND

         Traditional Enterprise Resource Planning ("ERP") systems have
product-centric views of the manufacturing enterprise. These business systems
provide decision-makers with an excellent understanding of product attributes
including material costs, bill of materials, labor costs and other attributes.
However, these business systems generally have no concept of the target process
parameters for actually producing finished goods or the actual process
parameters and conditions that occurred to generate specific lots of finished
goods.

         Traditional process control systems have an excellent process-centric
view of manufacturing. They understand how things are made, target process
parameters and material movement. However, process control systems generally do
not have any concept of the actual product made - lot numbers, yield, quality
attributes, costing information, etc.

         To make effective and efficient production decisions, both types of
information - product and process - must be used. This integration raises a
fundamental issue of how to create communication between the disparate nature of
business and process control systems. The Company's products are designed to
integrate business and process control systems for any production focused
enterprise.

FACTORYLINK(R)

         FactoryLink allows customers to collect and monitor data from disparate
process control systems. FactoryLink acts as hub for real-time information that
may be used by various decision makers interested in the real-time status of the
production process. In 1999, a new version of FactoryLink was released that
enhances the product's already solid reputation for reliability, scalability and
flexibility.

         To simplify connecting to plant floor devices, the Company includes
support for OLE for Process Control ("OPC") in FactoryLink, making it an
interoperable server that can collect and distribute data throughout a
multi-vendor manufacturing environment. FactoryLink's extensive database
connectivity and interfaces to MES and ERP products allow it to function as the
automation system hub, much broader than just HMI. Customers can now leverage
their existing investments in various HMIs and build an integrated system,
thereby eliminating existing islands of automation.

         The FactoryLink software enables a customer to:

     o   Create easy to use, real-time supervisory control applications that
         provide dynamic graphical representations of manufacturing and other
         automated processes;

     o   Design, test and build an automation application without computer
         programming knowledge through the use of an interactive graphical
         interface, pull-down menus, mouse-driven, point-and-click commands and
         fill-in-the-blank configuration tables;

     o   Develop automation applications that are portable and scaleable from
         low-end to high-end systems;

     o   Deploy completed applications easily and economically throughout an
         enterprise that may use different types of computer hardware and
         operating systems;

     o   Provide an upgrade path by allowing easy  modification of applications
         in response to customers' changing business needs; and

     o   Maintain completed applications in an efficient and cost effective
         manner.

         FactoryLink's architecture permits the user to pick and choose the
exact functionality required for a particular application. It allows the user to
design high performance, real-time systems capable of handling large amounts of
data. Techniques for exception processing, message compression and high-speed
data transfer achieve optimal functionality under this architectural
arrangement.

         In 1998, the Company released Year 2000 ready versions on all major
FactoryLink platforms historically supported by the Company, including DOS,
UNIX, OS/2, Microsoft Windows, NT and Windows 95. To provide the Company's


                                       3
<PAGE>   4


customers with a convenient means to obtain information regarding Year 2000
readiness of its products, the Company has maintained a web site
(www.usdata.com) with the latest information regarding Year 2000 readiness for
its products, including a statement of what it means when a product is
designated as Year 2000 ready. No significant Year 2000 related problems have
been reported with the Company's software products with the transition from 1999
into early 2000.

Xfactory(R)

         Xfactory is an MES product, which incorporates Microsoft's newest
technologies and is built on Microsoft's DNA architecture. Xfactory enables
manufacturing plants to more easily and quickly automate their production
processes and is the first visual object modeling MES. Xfactory bridges the gap
between the plant floor and ERP systems. The Company develops, markets and
supports Xfactory software products for customers requiring enterprise-wide,
open systems solutions for production management and leveraging business and
planning systems. The Xfactory software product enables customers to develop
versatile and flexible MES applications for production management, product
tracking, product scheduling, and genealogy tracking for manufacturing and
production processes. The information provided by the Company's products enables
customers to reduce operating costs, improve product quality and increase
overall throughput and productivity.

         In December 1999, the Company launched the latest release of Xfactory.
This latest release, Xfactory version 1.4, enables manufacturers of all sizes to
track and improve production processes "on the fly." Version 1.4 is intended to
deliver unparalleled performance and reliability for even the most demanding,
large-scale, production processes.

         Xfactory software enables a customer to:

     o   Utilize a fixed data base scheme, where the objects themselves are
         stored in the same database;

     o   Effectively convert the plant network into an intelligent event routing
         entity, allowing the customer to effortlessly send and receive local
         and remote event notifications;

     o   Maintain object-oriented programming that allows base objects to
         incorporate properties, events and methods, thereby easing the demands
         of large-scale software development and applying object modeling to the
         manufacturing plant itself;

     o   Utilize a three-tiered architecture that is intended to provide greater
         security, optimized client database connections, centralized
         management, thin clients and distributed processing for greater speed
         and throughput than is found in traditional single-tiered architectures
         (Xfactory clients reside on Tier 1, components in the Microsoft
         Transaction Server on Tier 2 and a client/server relational database on
         Tier 3); and

     o   To incorporate Xfactory functionality into environments such as Visual
         Basic, C/C++, Microsoft Office, Oracle Forms and SCADA packages, such
         as FactoryLink, because Xfactory is component based and Internet
         compatible.

USDATA CONNECTOR

         In the latter part of 1999 the Company introduced the USDATA Connector
product. USDATA Connector links the plant floor to the supply chain and
higher-level business systems. USDATA Connector is designed to enable disparate
systems throughout the enterprise to operate as one and, in conjunction with the
Company's production suite of software, to provide visibility to the status of
the customers order at any point in the manufacturing process. In this regard,
USDATA Connector assists manufacturers in achieving a real-time supply chain
allowing them to better meet changing customer needs and increasing market
demands.

USDATA ANALYSIS

         In late 1999 the Company also introduced its USDATA Analysis product.
USDATA Analysis turns production data into valuable information available from
any web browser. This product is the result of USDATA's intuitive production
modeling environment coupled with the capabilities of TopTier Software's
hyper-relational technology. USDATA Analysis provides integration of Xfactory
data with MySAP.com and Baan Data Navigator capabilities, allowing information
to be exported to Microsoft Excel or Access for further manipulation, or to be
saved in each user's USDATA Analysis desktop.

EMAKE SERVICES AND SOLUTIONS


         The Company established the eMake division to enable eMake to become a
premier provider of Internet-based manufacturing software and services from the
plant-floor to the executive office, across the supply chain. The Company
anticipates that the eMake division will enable B2B real-time visibility,
production and commerce. The Company intends to develop and implement an eMake
suite of Internet applications that will deliver a real-time production portal
with secure, online shop floor visibility and an eBusiness trading market that
is designed specifically for manufacturers.


         The Company expects that its initial focus for the eMake division will
be the development and implementation of the eMake Small Manufacturing Edition
products, which is designed for smaller make-to-order manufacturers, typically
with annual revenues less than $50 million. The Company intends to use the
expertise of the Smart Shop Software unit as the core of this offering. The
Company also expects to focus the eMake division on the development and
implementation of the eMake Production Edition, which is intended to provide
solutions to larger manufacturers in the electronics assembly and automotive
industries. The Company currently anticipates that the eMake Production Edition
will be introduced in late 2000. The Company also intends to provide eMake
division customers with a variety of services and solutions, including Internet
supply chain connectivity, web browser interfacing, production system management
and material resource planning capabilities.


MARKETING, SALES AND DISTRIBUTION

         The Company's sales and support organization includes channel
management personnel, a corporate business development group for lead
generation, a technical resource group and a network of authorized worldwide
distributors that acquire licenses for the Company's products at a discount and
remarket and provide training, customer support and consulting services to
end-users. The Company's sales and support organization combines its internal
resources with the resources, expertise and customer base of qualified third
party distributors, remarketers and integrators. The Company's internal sales
and marketing organization consisted of 48 persons as of December 31, 1999 and
is based in Richardson, Texas. The Company has field sales locations in 19 other
cities in the United States and in Belgium, England, Denmark, Germany, France
and Italy.

         The Company goes to market via a network of distributors, referred to
as tier one partners ("TOPs"). As of December 31, 1999, approximately 40 such
TOPs delivered in excess of 90% of the Company's products to system integrators
and the ultimate end-users. This indirect strategy is critical to the Company's
success and future growth because each TOP functions as a virtual extension of
the Company's sales, service and support. Typically, the business model of TOPs
is primarily driven by industrial software revenues and related products. TOPs
generally have value-added products and services that are additive to the
Company's core products, and TOPs generally work cooperatively with a community
of local system integrators that actually perform project work for the end-user.

         In support of its channel sales efforts, the Company conducts
comprehensive marketing programs that include direct mail, public relations,
advertising, seminars, trade shows and ongoing customer communications programs.
The Company also seeks to stimulate interest in its products and to keep its
customers informed of advances in application development technology through
demonstrations, promotional seminars, publications, technical notes and
newsletters.

CUSTOMER SERVICE

         The Company believes a high level of customer service and technical
support is critical to customer satisfaction, especially since many of the
Company's customers use its products to develop complex, large-scale
applications on which the success of their organizations may depend. The Company
has established, and intends to continue to enhance and expand, an integrated,
highly skilled channel service and technical support organization.

         The Company provides first level, localized support through its highly
qualified and experienced TOPs. Support engineers are networked utilizing a
single knowledge based system that is intended to enable quick and efficient
transfer of data, software corrections and up to date technical information. In
addition to frequent interaction between the Company's support personnel and the
TOPs engineers, the Company also conducts regular training sessions to enhance
the technical knowledge and working relationship in this support community.
Annual software support agreements are available to customers in various forms.

         The Company also provides customer support for its products via the
web, allowing users access to the latest software fixes, FAQ's (frequently asked
questions), detailed examples and on-line trouble shooting/problem submission.
The Company also maintains a FactoryLink Certified Integration Partner Program.
Members of this program have access to specific vertical market and industry
expertise and established relationships with prominent hardware and software.

         The Company offers comprehensive training classes to customers and
third-party remarketers. Training classes are offered through in-house training
facilities in Richardson, Texas, in facilities in Brussels, Belgium and through
its authorized training TOPs throughout the world. The training curriculum is a
comprehensive program of application development training in a hands-on,

                                       5
<PAGE>   6


lab-based training environment. The Company is also able to provide on-site
training when required by customers.



CUSTOMERS

         Since the introduction of the FactoryLink software product in 1986, the
Company has licensed more than 45,000 copies of the product worldwide for use in
the chemical, oil and gas, food, beverage, public utility, pharmaceutical, pulp
and paper, automotive, aerospace, electronics, telecommunications, water
treatment, transportation and numerous other industries. Established end users
include Anheuser-Busch Companies, Inc., Ford Motor Company, Goodyear Tire &
Rubber Company, Hewlett-Packard Company, Michelin Tire Corporation and Nestle
Food Company. In the year ended December 31, 1999, no single end user of the
Company's products accounted for more than 10% of the Company's total revenues.

         Sales to foreign clients (primarily in Europe) continue to be a
significant source of revenue for the Company. For the year ended December 31,
1999, the Company realized revenues from its international operations of $13.7
million (51% of revenues), as compared with $12.9 million for the comparable 12
month period (56% of revenues) ended December 31, 1998. Most of the Company's
international revenues were derived from sales and services related to
FactoryLink software products. See also Note 11 to Notes to Consolidated
Financial Statements for additional information on export revenues.

         The Company has maintained a long-term partner relationship with
Schneider Automation. Schneider and its predecessors have been purchasing for
resale a private label, OEM version of FactoryLink from the Company since 1989
and accounted for $4.9 million and $4.1 million or 18% and 18%, respectively, of
total revenues for the years ended December 31, 1999 and 1998, respectively.

         The Company's eMake division, including the Smart Shop Software unit,
serves a broad base of customers. Over 12,000 client licenses of the Company's
Smart Shop Software unit product, Smart Manager, have been installed with
make-to-order manufacturers since the introduction of the product by Smart Shop
Software, Inc. (Idaho), the predecessor to the Smart Shop Software unit.

PRODUCT INNOVATION AND DEVELOPMENT

         The Company's product development efforts are focused on expanding the
Company's portfolio of software products as well as maintaining the
competitiveness of its current products, including development of future
releases, improvements in the ease of use of its products and creation of new
application modules and development tools as well as the development of new
products that enable manufacturing performance improvement. The independence of
its products from underlying hardware platforms, GUIs, RDBMSs, networks and
other technologies and standards gives the Company the flexibility to evaluate a
wide range of new opportunities to expand the current scope of its products. The
Company's development activities generally are driven by market requirements and
to the extent possible leverage known technologies and architectures.

          The Company's eMake division product development efforts primarily
have been focused on the new eMake solutions and services including preparation
for application service provider hosting, web-based marketing and fulfillment,
and product enhancements.

         During the years ended December 31, 1999 and 1998, the Company invested
approximately $5.4 million and $5.2 million, respectively, in product
development including $2.5 million of capitalized software development costs in
both 1999 and 1998. In the years ended December 31, 1999 and 1998, the Company
expended 11%, and 12%, respectively, of its total revenues on product
development, net of capitalized software. The Company anticipates that it will
continue to commit substantial resources to product development in the future.

COMPETITION

         The software markets in which the Company participates are intensely
competitive and are subject to rapid changes in technology and frequent
introductions of new computer platforms and software standards. As a result, the
Company must continue to enhance its current products and to develop new
products in a timely fashion to maintain and improve its position in this
industry. The Company competes generally on the basis of product features and
functions, product architecture, the ability to run on a variety of computer
platforms and operating systems, technical support and other related services,
ease of product integration with third party applications software, price and
performance.

         The Company's FactoryLink product competes with a number of software
suppliers, including Intellution, owned by Emerson Electric, GEF Automation,
owned by FEF-Fuanuc, Rockwell Software, owned by Rockwell Automation and


                                       6
<PAGE>   7


Wonderware Corporation, owned by Siebe plc, as well as large PLC and DCS
manufacturers that provide similar software along with their hardware products.

         The Company's Xfactory product competes with a number of software
suppliers, including GR Software, owned by Genrad Corporation, Consilium owned
by Applied Materials, Promis Systems owned by Brooks Automation, Camstar Systems
Inc., RWT Corporation, as well as smaller software companies that provide
similar software.

         The Company's Smart Manager product competes with a number of software
suppliers, including Visual Manufacturing, owned by Lilly Software, Made2Manage,
Job Boss Software and Epicor.

         Additionally, certain businesses develop these types of systems
internally. Many of the Company's existing and potential competitors have longer
operating histories and significantly greater financial, technical, sales,
marketing and other resources than the Company. Certain of these organizations
also have greater name recognition and a larger installed product base than the
Company. The Company's competitors could introduce products in the future with
more features and lower prices than the Company's product offerings. These
organizations could also bundle existing or new products with other products or
systems to compete with the Company. As the market for industrial automation and
process control software products develops, a number of companies with
significantly greater resources than the Company could attempt to increase their
presence in this market by acquiring or forming strategic alliances with
competitors of the Company. Any of these events could have a material adverse
effect on the Company's business, prospects, operations and financial condition.

BACKLOG

         The Company typically ships software products within a short period of
time after acceptance of purchase orders. Accordingly, the Company typically
does not have a material backlog of unfilled orders for its software products,
and revenues in any quarter are substantially dependent on orders booked in the
quarter. Any significant weakening in customer demand would therefore have an
almost immediate adverse impact on the Company's operating results and on the
Company's ability to maintain profitability.

INTELLECTUAL PROPERTY

         The Company holds patents in the United States covering control systems
that employ the features embodied in its FactoryLink product. The Company has
registered its "USDATA," "FactoryLink" and "Xfactory" trademarks with the U.S.
Patent and Trademark office, as well as in several foreign countries.

         The Company regards its software as proprietary and attempts to protect
it with a combination of patent, copyright, trademark and trade secret law,
license agreements, nondisclosure and other contractual provisions and technical
measures. The Company requires employees to sign an agreement not to disclose
trade secrets and other proprietary information.

         The Company's software products generally are licensed to end-users
under a perpetual, non-transferable, nonexclusive license that stipulates which
modules can be used and how many concurrent controllers may use them. The
Company relies primarily on "shrink wrap" licenses for the protection of its
products. A shrink wrap license agreement is a printed and/or electronic license
agreement included with the packaged software that sets forth the terms and
conditions under which the purchaser can use the product and binds the purchaser
by its acceptance and purchase of the software to such terms and conditions. In
addition, in some instances the Company licenses its products under agreements
that give licensees limited access to the source code of the Company's products.

         The Company believes that existing intellectual property laws and other
protective measures afford only limited practical protection for the Company's
software. Furthermore, the laws of some foreign countries do not protect the
Company's proprietary rights to the same extent as do the laws of the United
States. Shrink-wrap licenses typically are not signed by the licensee and
therefore may be unenforceable under the laws of certain jurisdictions.
Accordingly, despite precautions taken by the Company, it may be possible for
unauthorized third parties to copy or reverse-engineer certain portions of the
Company's products or to obtain and use information that the Company regards as
proprietary.

         While the Company's competitive position could be threatened by its
inability to protect its proprietary information, the Company believes that,
because of the rapid pace of innovation within its industry, factors such as the
technological and creative skills of the Company's personnel are more important
to establishing and maintaining a technology leadership position within the
industry than are the various legal protections available for its technology.

         As the number of software products in the industry increases and the
functionality of these products further overlaps, the Company believes that
software programs could increasingly become the subject of infringement claims.
Although the Company's products have not been the subject of an infringement
claim, there can be no assurance that third parties will not assert infringement
claims against the Company in the future or that any such assertion will not
result in costly litigation or require the Company to obtain a


                                       7

license to use the intellectual property rights of such parties. In addition,
there can be no assurance that such a license would be available on reasonable
terms or at all.

EMPLOYEES

         As of December 31, 1999, the Company had approximately 204 full-time
employees. None of the Company's employees are subject to a collective
bargaining agreement, and the Company has not experienced any work stoppage. The
Company believes that its relations with its employees are good.

ITEM 2.     PROPERTIES

         The Company leases approximately 50,000 square feet of office space in
Richardson, Texas. The lease agreement for this office space was due to expire
in 2000. In February 2000, the Company amended the lease to extend the lease
term to 2010 and increase leased office space by approximately 30,000 square
feet in equal increments by mid-2000 and 2001. The Company leases additional
office space in other cities in the United States and in Europe. The Company
considers its leased real property adequate for its current and reasonably
foreseeable needs. The Company believes that suitable additional or alternative
space will be available as needed to accommodate the expansion of corporate
operations and additional sales offices.

ITEM 3.     LEGAL PROCEEDINGS

         The Company is involved in various legal actions incidental to the
normal conduct of its business. The Company does not believe that the ultimate
resolution of these actions will have a material adverse effect on the Company.

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

         None.

Stock. The Company currently intends to retain future earnings for use in its
business and, therefore, does not anticipate paying any cash dividends in the
foreseeable future. Future dividends, if any, will depend on, among other
things, the Company's results of operations, capital requirements, restrictions
in loan agreements and financial condition and on such other factors as the
Company's Board of Directors may, at its discretion, consider relevant.

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

OVERVIEW

         USDATA Corporation (the "Company"), is a global supplier of
component-based production software that is designed to help customers reduce
operating costs, shorten cycle times and improve product quality in their
manufacturing operations. The Company's software enables manufacturers to access
more accurate and timely information - whether they are on the plant-floor, in
the office, or around the globe. The Company's solutions span a wide range of
manufacturing processes, from monitoring equipment to tracking product flow, and
are designed to integrate seamlessly with customers' existing manufacturing and
business software. This combination of product breadth and ease of integration
is intended to provide a total plant solution that defines new levels of
manufacturing performance and gives customers a distinct competitive advantage.
Now in its 25th year, the Company has a strong global presence with more than
45,000 installs located in more than 60 countries throughout the world, 19
offices worldwide and a global network of distribution and support partners.

         Revenues have been generated primarily from licenses of the Company's
FactoryLink, Xfactory and Smart Manager software and secondarily from technical
support and service agreements, training classes and product related services.
The support and service agreements are generally one-year, renewable contracts
entitling a customer to certain software upgrades and technical support. Support
and service revenue represented approximately 11%, 12% and 11% of revenues
during the years ended December 31, 1999, 1998, and 1997, respectively.


                                       10
<PAGE>   11


         Included in the FactoryLink family of products are versions 6.5 and
6.6, real-time information Windows NT and Windows 98/95 platforms, supporting
powerful client access environments and technologies and providing Year 2000
("Y2K") readiness. In addition, the Company offers FactoryLink WebClient, which
provides the ability to view and control any FactoryLink server running
Microsoft Windows NT using a simple web browser.

         Xfactory, which was introduced in mid-1998, is a manufacturing
execution software ("MES") product that incorporates Microsoft's newest
technologies and is built on Microsoft's Distributed Internet Applications
("DNA") architecture. Xfactory enables manufacturing plants to more easily and
quickly automate their production processes and is the first visual object
modeling MES. The Xfactory software product enables customers to develop
versatile and flexible MES applications for production management, product
tracking, product scheduling and genealogy tracking for manufacturing and
production processes.

         In December 1999, the Company released Xfactory version 1.4 which gives
manufacturers of all sizes the ability to track and improve production processes
"on the fly." Version 1.4 is intended to deliver unparalleled performance and
reliability for even the most demanding, large-scale, production processes.

         In August 1999, the Company acquired the business of Smart Shop
Software, Inc. (Idaho), ("Smart Shop") which provides business software for
make-to-order small and medium sized manufacturers (see Note 2 "Acquisitions"),
principally the Smart Manager software product.

         During 1999, the Company also announced the formation of its new eMake
division, which is focused on the "make" or production area of the manufacturing
supply chain. Through the eMake division, the Company intends to provide a suite
of Internet applications that will include integrated product solutions and
real-time visibility across the supply chain. The Company's strategy is to
leverage its extensive manufacturing knowledge through Internet applications to
help companies maximize their back office production and create the eMake portal
for front office visibility into the production operations of the supply chain.
Initial product availability is targeted for early to mid 2000 and the Company
anticipates that the division initially will focus on horizontal make-to-order
solutions for smaller manufacturers and industry solutions for larger-scale
automotive and electronics assembly. This division also includes the Smart Shop
Software products and operations.

         The Company focuses its sales efforts through selected distributors
capable of providing the level of support and expertise required in the
real-time manufacturing and process control application market. The Company
currently has seven channel support locations in the United States and six
internationally to support its sales efforts through its network of
distributors.

       Effective July 1, 1998, the Company sold its Auto ID hardware integration
and servicing business ("Systems Operations"). In conjunction therewith, during
the first quarter of 1998, the Company reported a loss of $1.25 million related
to the disposal thereof and $469 thousand related to operations through the date
of disposal.

         This document contains "forward-looking statements" within the meaning
of the Private Securities Litigation Reform Act of 1995 regarding revenues,
margins, operating expenses, earnings, growth rates and certain business trends
that are subject to risks and uncertainties that could cause actual results to

         Total revenues for 1999 were $27.0 million, an increase of $4.2 million
or 18%, compared to 1998. The increase was primarily a result of a $2.8 million
increase in software licensing and support revenue related to the Company's
USDATA product division, which includes its FactoryLink and Xfactory product
lines, as well as $1.4 million of revenues from the Company's eMake product
division. North American and international revenues were 49% and 51%,
respectively, of total revenues during 1999. North American and international
revenues increased 34% and 6%, respectively, in 1999 compared to 1998.

         Selling and product materials expenses increased $1.2 million or 7% in
1999 compared to 1998. This increase is primarily a result of increased product
materials cost of $.3 million, a $.2 million increase in marketing expenses from
the Company's USDATA product division and a $.7 million increase in marketing
expenses from the Company's eMake product division. Selling and product
materials expenses as a percentage of revenues decreased to 65.8% for the year
ended December 31, 1999 from 72.5% for the same period in 1998.

         Product development expenses (net of capitalized software development
costs), which consisted primarily of labor costs, increased $.2 million in 1999
compared to 1998. The increase is attributable to eMake development expenses of
$.4 million and development efforts for the Xfactory product line, offset by a
decrease in contract engineering development activities related to the


                                       12

FactoryLink product line. The Company capitalized $2.5 million of development
expenses in both 1999 and 1998, primarily related to the next major version of
the FactoryLink product.

         General and administrative expenses increased $.5 million or 8% for the
year ended December 31, 1999. This increase is primarily attributable to Smart
Shop's general and administrative expenses of $.4 million, which are included in
the eMake product division. General and administrative expenses as a percentage
of revenues decreased to 23.9% for the year ended December 31, 1999 from 26.1%
for the same period in 1998, as a significant portion of general and
administrative expenses are fixed in nature.

         In connection with the acquisition of Smart Shop, the Company recorded
$1.7 million in charges, including non-cash compensation of $659 thousand,
amortization of acquired intangible assets of $595 thousand and a charge of $476
thousand to write-off acquired in-process research and development.

         The Company experienced a loss from continuing operations of $2.4
million in 1999 versus a loss of $2.1 million in 1998. The increase in loss from
continuing operations was primarily the result of the acquisition related
charges of $1.7 million and eMake related costs associated with developing
technology, building the infrastructure, start-up and Smart Shop operating
expenses.

COMPARISON OF YEARS ENDED DECEMBER 31, 1998 AND 1997

         Total revenues for 1998 were $22.9 million, an increase of $.5 million
or 2% compared to 1997. During 1998, the Company's software licensing revenues
increased 11% compared to 1997 and overall unit shipments of software licenses
increased at an even greater rate, particularly in products for the Microsoft
Windows NT and Windows 95 platforms while products for Unix and other operating
systems platforms declined compared to the prior year. The net result of this
product mix shift was reflected in lower overall average selling prices (ASPs)
for the Company's products which partially offset the positive impact of
increased unit shipments. However, during the latter part of 1998 the Company's
ASPs began to stabilize as over 90% of all unit shipments were for Windows NT
and Windows 95 platforms in 1998 compared to 80% in 1997. Revenues from product
related consulting declined substantially from 1997 reflecting the Company's
decision to refer nearly all such activity to its channel distribution partners.
North American revenues decreased by 22% while international revenues increased
34% in 1998 compared to 1997. North American revenues and International revenues
were 44% and 56% of total revenues, respectively.

         Selling and product materials expenses as a percent of revenues was
72.5% in 1998. Selling and product materials expenses decreased $1.1 million in
1998 compared to 1997 due to decreased product materials costs of $1.4 million
as the result of replacement of printed product documentation with compact disk
(CD) based product documentation and decreased capitalized software development
amortization costs resulting from all such capitalized costs being fully
amortized except for development costs related to future unreleased products,
offset by an increase in marketing activities resulting from the Xfactory
product introduction, demonstration CD's, sales collateral material, as well as
seminars and travel related to training activities for the Company's channel
partners.

         Product development expenses (net of capitalized software development
cost), which consisted primarily of labor costs, decreased $.9 million or 25% in
1998 compared to 1997. Actual product development expenditures, including
capitalized software development costs of $2.5 million in 1998 and $2.2 million
in 1997, decreased $.3 million or 5.6% in 1998 compared to 1997. The development
of the double-byte functionality supporting the Japanese, Chinese and Korean
languages in 1997 was one of the primary factors in the higher level of spending
in 1997 compared to 1998.

         General and administrative costs decreased $1.4 million or 19% in 1998
compared to 1997. As a percent of revenues, general and administrative decreased
to 26.1% in 1998 versus 32.9% in 1997. The decrease from 1997 was primarily
attributable to decreased provisions for bad debt expenses and organizational
restructuring expenses.

         The Company experienced a loss from continuing operations of $2.1
million in 1998 versus a loss of $3.9 million in 1997. The decrease in the loss
from continuing operations was primarily generated by an increase of $1.9
million in gross profit due to improved gross profit margins in combination with
increased revenues and a decrease of $2.0 million in operating expenses,
partially offset by a significant reduction in the tax benefit resulting from
the Company's inability to utilize tax net operating loss carrybacks in 1998
compared to 1997.

         Discontinued operations incurred a loss of $1.7 million in 1998
resulting from the loss on disposal and the loss from operations until the date
of disposal compared to income of $.2 million in 1997. The loss on disposal and
from operations until the date of disposal in 1998 were both affected by
declining revenues compared to prior years.

LIQUIDITY AND CAPITAL RESOURCES

         The Company's operating activities provided $1.2 million of cash for
the year ended December 31, 1999 compared to $.4 million for the same period in
1998, primarily due to improved collections on accounts receivable. Cash used in
investing activities was $10.1 million for the year ended December 31, 1999
primarily due to the acquisition of Smart Shop for $6.4 million in cash, plus
transaction costs of $.2 million. In addition, the Company invested $1.0 million
in capital equipment, primarily computers and equipment, and $2.5 million in
capitalized software development costs. The Company received $10.0 million in
cash related to the issuance of 1,204,819 shares of its common stock for $5.0
million and 50,000 shares of its Series A preferred stock for $5.0 million.

         The Company's capital asset requirements are generally funded through
internally generated funds. The Company anticipates that capital equipment
expenditures will be approximately $1.1 million in 2000.

         Working capital was approximately $3.1 million at December 31, 1999,
compared with approximately $3.0 million at December 31. 1998.

         On February 8, 2000 and March 24, 2000, the Company received $2.5
million and $2.5 million, respectively, in financings from a wholly owned
subsidiary of Safeguard. The Company has not finalized the terms and provisions
of these financings.

         The Company's liquidity needs are expected to arise primarily from
funding continued development, enhancement and support of its current and new
software products, and the related selling and marketing expenses. The Company
is in the process of seeking additional public or private debt or equity
financing to fund future growth opportunities or acquisitions. No assurance can
be given, however, that such debt or equity financing will be available to the
Company on terms and conditions acceptable to the Company, if at all.

YEAR 2000 COMPLIANCE

       The Company has evaluated the Year 2000 ("Y2K") issue and adjusted all
known date-sensitive systems and equipment for Y2K compliance. The assessment,
remediation and testing phases of the Y2K project are complete. The Company has
not encountered any material problems in its critical systems or products
subsequent to December 31, 1999 related to the Y2K issue and has not encountered
any material problems with its third party vendors and suppliers. The Company
will continue to monitor new issues or concerns relative to Y2K.

       To date, the Company has not incurred any material costs of compliance
with Y2K for its internal IT and non-IT computer systems. For primarily
operational purposes, the Company had been upgrading PCs and individual
applications running thereon throughout 1999, 1998 and 1997. The Company's
internal resources performed virtually all of the Y2K readiness issues and the
Company plans to use its internal resources to address any issues that may yet
arise.

       Although the Company to date has not experienced any significant problems
associated with Y2K, the Company cannot be certain that unexpected Y2K
compliance problems of its products, computer systems or the systems of its
vendors, customers and service providers, will not occur. Any such problems
could have a material adverse affect on the Company's business, financial
condition or operating results.

RECENT ACCOUNTING PRONOUNCEMENTS

         In June 1998, the Financial Accounting Standards Board released
Statement No. 133, "Accounting for Derivative Instruments and Hedging
Activities" ("SFAS 133"), as amended by SFAS No. 137, which is effective for
fiscal years beginning after June 15, 2000. Earlier application for certain
provisions of this standard is permitted. SFAS 133 establishes accounting and
reporting standards for derivative instruments. The Statement requires that an
entity recognize all derivatives as either assets or liabilities in the
financial statements and measure those instruments at fair value, and it defines
the accounting for changes in the fair value of the derivatives depending on the
intended use of the derivative. SFAS 133 is not expected to have a material
impact on the Company's consolidated results of operations, financial position
or cash flows.

ITEM 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

         The Company's exposure to market risk associated with changes in
interest rates relates to its variable rate bank note payable of $276,000.
Interest rate risk is estimated as the potential impact on the Company's results
of operations or financial position due to a hypothetical change of 50 basis
points in quoted market prices. This hypothetical change would not have a
material effect on the Company's results of operations and financial position.

ITEM 8.     FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

         The consolidated financial statements and supplementary data of the
Company begins on page F-1 of this report. Such information is hereby
incorporated by reference into this Item 8.

ITEM 9.     CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND
FINANCIAL DISCLOSURE

         On November 11, 1999, we dismissed PricewaterhouseCoopers LLP as our
independent accountants and engaged KPMG LLP as our independent accountants. We
have retained KPMG LLP for the current year ending December 31, 2000. Our Audit
Committee participated in and approved the decision to change independent
accountants. The reports of PricewaterhouseCoopers LLP on the financial
statements for the past two fiscal years contained no adverse opinion or
disclaimer of opinion and were not qualified or modified as to uncertainty,
audit scope or accounting principle. In connection with its audits for the two
most recent fiscal years and through November 11, 1999, we have had no
disagreements with PricewaterhouseCoopers LLP on any matter of accounting
principles or practices, financial statement disclosure, or auditing scope or
procedure, which disagreements if not resolved to the satisfaction of
PricewaterhouseCoopers LLP would have caused them to make reference thereto in
their report on the financial statements for such years. PricewaterhouseCoopers
LLP furnished us with a letter addressed to the Securities and Exchange
Commission stating that it agreed with the above statements. A copy of the
letter, dated November 15, 1999, is filed as Exhibit 16 to our Current Report on
Form 8-K, filed with the Securities and Exchange Commission on November 11,
1999.

         A representative of KPMG LLP is expected to be present at the annual
meeting and will have an opportunity at the meeting to make a statement if he or
she desires to do so, and will be available to respond to appropriate questions.

                          INDEPENDENT AUDITORS' REPORT


THE STOCKHOLDERS AND BOARD OF DIRECTORS OF
USDATA CORPORATION:

         We have audited the accompanying consolidated balance sheet of USDATA
Corporation and subsidiaries as of December 31, 1999, and the related
consolidated statements of operations and comprehensive loss, stockholders'
equity, and cash flows for the year then ended. In connection with our audit of
the consolidated financial statements, we also have audited the financial
statement schedule as listed in the accompanying index. The consolidated
financial statements and financial statement schedule are the responsibility of
the Company's management. Our responsibility is to express an opinion on the
consolidated financial statements and financial statement schedule based on our
audit.

         We conducted our audit 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 our audit provides a reasonable basis for our opinion.

         In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of USDATA
Corporation and subsidiaries as of December 31, 1999, and the results of their
operations and their cash flows for the year then ended 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.

                        REPORT OF INDEPENDENT ACCOUNTANTS


TO THE BOARD OF DIRECTORS AND STOCKHOLDERS OF USDATA CORPORATION

In our opinion, the consolidated balance sheet and the related consolidated
statements of operations and comprehensive income, of stockholders' equity and
of cash flows listed in the index appearing under Item 14 (a) (1) and (2) on
page 16 present fairly, in all material respects, the financial position of
USDATA Corporation and its subsidiaries (the "Company") at December 31, 1998 and
the results of their operations and their cash flows for each of the two years
in the period ended December 31, 1998, in conformity with generally accepted
accounting principles. 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 of these
statements in accordance with generally accepted auditing standards which
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, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for the opinion expressed above.

and its wholly-owned subsidiaries. All intercompany accounts and transactions
have been eliminated.

CASH EQUIVALENTS

       The Company considers all highly liquid investments purchased with
maturities of three months or less at the time of purchase to be cash
equivalents.

PROPERTY AND EQUIPMENT

       Property and equipment are stated at original cost. Maintenance and
repairs are charged to expense as incurred, and the costs of additions and major
betterments and replacements are capitalized. Depreciation is provided in
amounts which amortize costs over the estimated useful lives of the related
assets, generally three to five years, utilizing the straight-line method.
Leasehold improvements are amortized over the lesser of the term of the
respective leases or estimated useful life of the improvement.

CAPITALIZED SOFTWARE

       Software development costs incurred prior to establishing technological
feasibility are charged to operations and included in product development costs.
Software development costs incurred after establishing technological
feasibility, and purchased software costs, are capitalized and amortized on a
product-by-product basis when the product is available for general release to
customers. Annual amortization, charged to cost of sales, is the greater of the
amount computed using the ratio that current gross revenues for a product bear
to the total of current and anticipated future gross revenues for that product,
or the straight-line method over the remaining estimated economic life of the
product. The total computer software development costs capitalized for 1999,
1998 and 1997 were $2.5 million, $2.5 million, and $2.2 million, respectively.
The total costs amortized and charged to operations for 1998 and 1997 were $.4
million and $1.4 million, respectively. No costs were amortized in 1999.

SOFTWARE HELD FOR RESALE

         In 1998, the Company purchased the underlying source code for a certain
software product, which is held for resale in the ordinary course of business.
The original purchase costs of such software were capitalized and are being
amortized utilizing the straight-line method over the estimated economic life of
three years. Total costs amortized and charged to cost of sales for 1999 and
1998 were $237 thousand and $59 thousand, respectively.

EXCESS OF COST OVER FAIR VALUE OF NET ASSETS OF BUSINESS ACQUIRED

         The excess of cost over fair value of net assets of business acquired
is being amortized on a straight-line basis over a period of 5 years.
Accumulated amortization was $427 thousand at December 31, 1999. The Company
continually evaluates the excess of cost over fair value of net assets of
businesses acquired for indications of impairment based on the forecasted
undiscounted cash flow from the related business activity. The amount of
goodwill impairment, if any, is measured based upon projected discounted future
operating cash flows using a discount rate reflecting the Company's average cost
of funds. The assessment of the recoverability of excess cost over fair value of
net assets of business acquired will be impacted if estimated future operating
cash flows are not achieved. The Company believes that no such impairment has
occurred and that no reduction in estimated useful lives is warranted.

INTANGIBLE AND OTHER ASSETS

         Intangible and other assets includes identifiable intangible assets
acquired, consisting of $1.7 million in developed technology, less accumulated
amortization of $147 thousand, and $251 thousand in assembled work force, less
$21 thousand in accumulated amortization, at December 31, 1999. These intangible
assets are amortized on a straight-line basis over the expected useful lives of
the assets of five years.

IMPAIRMENT OF LONG-LIVED ASSETS

       Long-lived assets and certain identifiable intangibles are reviewed for
impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable. Recoverability of assets to
be held and used is measured by a comparison of the carrying amount of an asset
to future net cash flows expected to be generated by the asset. If such assets
are considered to be impaired, the impairment is measured by the amount by which
the carrying amount of the assets exceeds the fair value of the assets. Assets
to be disposed of are reported at the lower of the carrying amount or fair value
less cost to sell.

REVENUE RECOGNITION

         Revenue from the licensing of software products is generally recognized
when the following criteria have been met: (a) a written contract for the
license of software has been executed, (b) the Company has delivered the product
to the customer, (c) the license fee is fixed or determinable, and (d)
collectibility of the resulting receivable is deemed probable. Revenue from
software support maintenance agreements is recognized ratably over the contract
term, generally not exceeding one year. Sales return rights are provided to
certain customers, under specified conditions. Revenues are presented net of
estimated returns, which historically have not been significant.

STOCK-BASED COMPENSATION

       In 1996, the Company adopted Statement of Financial Accounting Standards
("SFAS") No. 123, "Accounting for Stock-Based Compensation", which gives
companies the option to adopt the fair value method for expense recognition of
employee stock options and other stock-based awards or to continue to account
for such items using the intrinsic value method as outlined under Accounting
Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees"
("APB 25"), with pro forma disclosure of net income as if the fair value method
had been applied.

The Company has elected to continue to apply APB 25 for stock options and other
stock based awards and has disclosed pro forma net income (loss) as if the fair
value method had been applied.

INCOME TAXES

       Income taxes are accounted for under the asset and liability method. This
method results in the recognition of deferred tax liabilities and assets for the
expected future tax consequences of temporary differences between the carrying
amounts and the tax basis of assets and liabilities.

FINANCIAL INSTRUMENTS

       The carrying values of cash equivalents, accounts receivable and accounts
payable approximate fair value due to their short maturities. The carrying value
of the Company's bank note payable at December 31, 1999 approximates fair value
as this note payable bears interest at market rates.

NET LOSS PER SHARE OF COMMON STOCK

        Net loss per share of common stock is presented in accordance with the
provisions of SFAS No. 128, Earnings Per Share. Under SFAS No. 128, basic loss
per share excludes dilution for potentially dilutive securities and is computed
by dividing income or loss available to common stockholders by the weighted
average number of common shares outstanding during the period. Diluted
earnings(loss) per share reflects the potential dilution that could occur if
securities or other contracts to issue common stock were exercised or converted
into common stock. Potentially dilutive securities are excluded from the
computation of diluted earnings(loss) per share when their inclusion would be
antidilutive.

       Options to purchase 1.7 million, 1.2 million, and 1.2 million shares of
common stock for 1999, 1998 and 1997, respectively, and warrants to acquire 0.7
million, 0.8 million and 0.8 million shares of common stock for 1999, 1998 and
1997, respectively, were not included in the computation of diluted earnings per
share as their impact would be antidilutive.

FOREIGN CURRENCY TRANSLATION

         The Company translates the balance sheets of its foreign subsidiaries
using year-end exchange rates and translates statement of operations amounts
using the average exchange rates in effect during the year. The gains and losses
resulting from the change in exchange rates from year to year have been reported
separately as a component of accumulated other comprehensive income (loss) in
stockholders' equity. Gains and losses resulting from foreign currency
transactions are included in the statements of operations.

CONCENTRATION OF CREDIT RISK

         The Company licenses software and provides services to established
companies. The Company performs credit evaluations of its customers and
generally does not require collateral. The Company maintains reserves for
estimated credit losses. At December 31, 1999, the Company had two customers
with outstanding accounts receivable balances of approximately $1.3 million and
$1.7 million, respectively. In addition, these customers represented
approximately 18% and 6%, respectively, of the Company's revenues for 1999. At
December 31, 1998, the Company had one customer with an outstanding accounts
receivable balance of approximately $1.2 million. This customer represented
approximately 18% and 13% of the Company's revenues for 1998 and 1997,
respectively.

2.       ACQUISITION

         On August 6, 1999, the Company completed its acquisition of
substantially all of the assets and certain liabilities of Smart Shop Software,
Inc. ("Smart Shop") for $6.4 million in cash, plus transaction costs of $.2
million. This acquisition has been accounted for under the purchase method of
accounting. The excess purchase price over the estimated fair value of net
tangible assets has been allocated to various intangible assets, consisting of
developed technology of $1.8 million, assembled work force of $251 thousand and
goodwill of $5.2 million, all of which are being amortized to expense on a

straight-line basis over 5 years. Accumulated amortization at December 31, 1999
was $147 thousand, $21 thousand and $427 thousand, respectively. In addition,
$476 thousand of the purchase price was allocated to in-process research and
development costs. In-process research and development relates to several of
Smart Shop's research and development projects at various stages of development
related to Smart Manager 7.0, on which version Smart Shop began development in
March 1999. The value assigned to in-process research and development was
determined based on management's estimates of the percentage of completion of
the underlying development efforts, resulting net cash flows from Smart Manager
7.0 and the discounting of such cash flows back to their present value. The
results of the acquired business have been included in the consolidated
financial statements since the date of acquisition of August 6, 1999.

         In connection with the acquisition, the Company also issued 500,000
shares of common stock to certain former shareholders of Smart Shop who became
employees of the Company. The shares of common stock are held in escrow as
collateral for performance under the purchase agreement and shall be released
from escrow to the shareholders in six tranches each six months following the
closing date of August 6, 1999. In connection with these shares, deferred stock
compensation of $1.9 million was recorded in stockholders' equity. The deferred
stock compensation is being recognized as compensation expense over 36 months,
as the restrictions lapse. The Company recorded a non-cash compensation charge
of $659 thousand for the period ended December 31, 1999 related to the initial
amortization of this compensation charge.

         The following unaudited pro forma information presents the results of
operations of the Company as if the acquisition had occurred on January 1, 1999
and on January 1, 1998 and excludes the write-off of acquired in-process
research and development.

         At December 31, 1999, the Company had net operating loss carryforwards
of approximately $11.1 million, which will expire beginning in 2018.

         In assessing the realizability of deferred tax assets, the Company
considers whether it is more likely than not that some portion or all of the
deferred tax assets will not be realized. The ultimate realization of deferred
tax assets depends on the generation of future taxable income during the periods
in which those temporary differences become deductible. The Company considers
the scheduled reversal of deferred tax liabilities, projected future taxable
income, and tax planning strategies in making this assessment. Based upon these
considerations, the Company has fully reserved all deferred tax assets to the
extent such assets exceed deferred tax liabilities.

6.     DISCONTINUED OPERATIONS


         Effective July 1, 1998, the Company sold its Auto ID hardware
integration and servicing business ("Systems Operations"). In conjunction
therewith, during the first quarter of 1998, the Company reported a loss of
$1.25 million related to the disposal thereof and $469 thousand related to
operations through the date of disposal. As a result of this action, the
Company's revenues and operating expenses for the periods presented herein
reflect only the Software Operations with the net results of the Systems
Operations reported on its statements of operations under the caption
"Discontinued Operations". Revenues related to the Systems Operations were $3.1
million and $12.9 million for the years ended December 31, 1998 and 1997,
respectively.

7.     STOCKHOLDERS' EQUITY AND REDEEMABLE CONVERTIBLE PREFERRED STOCK

PREFERRED STOCK

         The board of directors is authorized, subject to certain limitations
and without stockholder approval, to issue up to 2.2 million shares of preferred
stock in one or more series and to fix the rights and preferences of each
series. In 1999, the board of directors designated 100,000 shares of authorized
but unissued preferred stock as Series A convertible preferred stock.

REDEEMABLE CONVERTIBLE PREFERRED STOCK

         On August 6, 1999, the Company issued through a private placement
50,000 shares of the Company's Series A convertible Preferred Stock for $5.0
million to a wholly-owned subsidiary of Safeguard Scientifics, Inc.
("Safeguard"), the Company's primary shareholder. The Series A Preferred Stock
has a par value of $.01 per share and a liquidation preference of $100 per share
plus cumulative dividends and interest. The Company is obligated to redeem the
shares at $100 per share plus accumulated dividends and interest at any time
after December 31, 2002. Dividends on the Series A Preferred Stock are
cumulative and payable at a rate of $8.00 per share per annum and in preference
to any dividends on the Company's common stock. Cumulative dividends are
interest bearing. The preferred stock is convertible at any time into shares of
common stock of the Company or into shares of common stock of any majority owned
subsidiary of the Company, at the election of the holder at a conversion rate of
$4.65 per share of common stock. At December 31, 1999, the aggregate redemption
value was $5,167 thousand based on cumulative dividends and interest of $167
thousand.

WARRANTS TO PURCHASE COMMON STOCK

         In 1994, the Company issued warrants to Safeguard and a director of the
Company to purchase common stock of the Company. The warrants entitled Safeguard
and the director to purchase 698,238 and 77,582 shares, respectively, of common
stock of the Company at an exercise price of $3.02 per share. These warrants
expire in November 2001. In December 1999, the director exercised his warrant to
purchase 77,582 shares of the Company's common stock. Warrants to purchase
698,238 shares of common stock are outstanding at December 31, 1999.

8.   EQUITY COMPENSATION PLANS

         In 1994, the Company adopted the 1994 Equity Compensation Plan (the
1994 Plan), which provides for stock options to be granted to employees,
independent contractors and directors. The 1994 Plan was amended in 1999 to
provide for the issuance of up to 2,500,000 shares of common stock pursuant to
the grant of incentive stock options (ISO), non-qualified stock options (NSO),
stock appreciation rights (SARs) and restricted stock awards. Options issued
under the 1994 Plan generally vest over a four-year period and are exercisable
up to eight years from the date of grant at a price per share equal to the fair
market value of the underlying stock on the date of grant. The 1994 Plan also
authorizes an automatic grant of options to purchase 15,000 shares of common
stock to certain eligible directors upon initial election to the board of
directors and a further grant of options to purchase 3,000 shares of common
stock following the completion of each two-year period of service. Options
granted to directors have a eight-year term and vest over four years. At
December 31, 1999, there were 253,000 shares available for future grant under
the 1994 Plan.

         The Company applies APB Opinion No. 25 in accounting for its stock
option grants under these plans, which are described above. Accordingly, no
compensation cost has been recognized for its stock option plans. If

OTHER

         The Company has other contingent liabilities resulting from litigation,
claims and commitments incident to the ordinary course of business. Management
believes that the ultimate resolution of such contingencies will not have a
materially adverse effect on the financial position or results of operations of
the Company.

13.    SEGMENT INFORMATION AND CONCENTRATION OF CREDIT RISK

           The Company defines its operations as operating segments based on two
distinct product divisions - the USDATA product division, which includes its
FactoryLink and Xfactory product lines, and the eMake product division, which
develops and distributes internet applications that deliver integrated
production solutions and real-time visibility across the supply chain and
includes the Company's recently acquired Smart Shop unit. The Company uses
revenues and income (loss) from continuing operations, which consists of
revenues less operating expenses, to measure segment operations.

         The amounts presented in the 1999 third quarter have been restated from
those amounts reported in the Company's 1999 Form 10-Q for the quarter ended
September 30, 1999 to reflect the inclusion of the Smart Shop operations from
the closing date of the acquisition, August 6, 1999. Amounts previously reported
included the Smart Shop operations as of the effective date of the acquisition,
July 1, 1999. The third quarter amounts have also been restated to give effect
to the amortization of goodwill and other identifiable intangibles over a
five-year useful life as opposed to the twenty-year amortization period
initially used.

         Earnings per share calculations are based on the weighted average
number of shares outstanding in each period; therefore, the sum of the earnings
per share amounts for the quarters does not necessarily equal the year-to-date
earnings per share.

                           CERTIFICATE OF DESIGNATION

                                       FOR
                            SERIES A PREFERRED STOCK
                                       OF
                               USDATA CORPORATION


          The undersigned, Robert L. Drury, the Chief Financial Officer of
USDATA Corporation, does hereby certify that:

          (a) he is, and at all times mentioned herein was, the duly elected and
          acting Chief Financial Officer of USDATA Corporation, a Delaware
          corporation (the "Corporation"); and

          (b) pursuant to Section 151 of the Delaware General Corporation Law,
          the Board of Directors of the Corporation adopted the following
          preamble and resolution on August 4, 1999:

          WHEREAS, the Corporation's Certificate of Incorporation authorizes a
class of stock designated Preferred Stock (the "Preferred Stock"), comprised of
2,200,000 shares, par value $0.01 per share, provides that such Preferred Stock
may be issued from time to time in one or more series, and vests authority in
the Board of Directors of the Corporation to fix or alter the rights,
preferences, restrictions and other terms and conditions of any wholly unissued
series of Preferred Stock;

     NOW, THEREFORE, BE IT:

          RESOLVED, that, the Board of Directors of the Corporation does hereby
designate 100,000 shares of authorized but unissued Preferred Stock as "Series A
Preferred Stock," and does hereby designate the voting powers, preferences and
relative participation, optional or other special rights and qualifications,
limitations or restrictions of the Series A Preferred Stock as follows:

          1. Dividends.

               a. The holders of the Series A Preferred Stock shall be entitled
to receive cumulative dividends at the rate of $8.00 per share per annum (as
adjusted for any stock dividends, combinations, splits or similar events)
whether or not earned or declared. Any accumulated dividends shall bear interest
at the rate of 8.00% per annum compounded annually. Such dividends and interest
thereon shall be payable, at the election of the Corporation, in additional
shares of Series A Preferred Stock (valued at $100.00 per share, as adjusted for
any stock dividends, combinations, splits or similar events) or in cash, (i)
when, as and if declared by the Board of Directors of the Corporation or (ii)
upon conversion of all of the Series A Preferred Stock to Common Stock pursuant
to Section 5 below.


<PAGE>   2


               b. No dividends or distributions of any sort (other than a
dividend payable solely in the Common Stock of the Corporation) shall be
declared or paid by the Corporation on any Common Stock of the Corporation so
long as any accrued dividends on the Series A Preferred Stock remain unpaid.

               c. In the event that the Corporation shall declare a dividend or
distribution payable in securities of other persons, evidences of indebtedness
issued by the Corporation or other persons, or options or rights to purchase any
such securities or evidences of indebtedness or other assets (including cash),
to the holders of Common Stock of the Corporation, then the holders of the
Series A Preferred Stock shall be entitled to a proportionate share of any such
dividend or distribution as though the holders of the Series A Preferred Stock
were the holders of the number of shares of Common Stock of the Corporation into
which their respective shares of Series A Preferred Stock are convertible as of
the record date fixed for the determination of the holders of the Common Stock
of the Corporation entitled to receive such dividend or distribution.

               d. All numbers relating to calculation of cumulative dividends or
the payment of dividends on the Series A Preferred Stock in kind shall be
subject to equitable adjustment in the event of any stock dividend, stock split,
combination, reorganization, recapitalization, reclassification or other similar
event involving a change in the capital structure of the Series A Preferred
Stock.

          2. Liquidation Preference.

               a. In the event of any liquidation, dissolution or winding up of
the Corporation, whether voluntary or involuntary, the holders of the Series A
Preferred Stock shall be entitled to receive, prior and in preference to any
distribution of any of the assets or surplus funds of the Corporation to the
holders of the Common Stock or any other series of Preferred Stock by reason of
their ownership thereof, an amount equal to $100.00 (as adjusted for any stock
dividends, combinations, splits or similar events) plus all accrued but unpaid
dividends and interest thereon (the "Liquidation Amount") for each share of
Series A Preferred Stock then held by them. If upon the occurrence of such
event, the assets and funds thus distributed among the holders of the Series A
Preferred Stock shall be insufficient to permit the payment to such holders of
the full Liquidation Amount, then the entire assets and funds of the Corporation
legally available for distribution shall be distributed ratably among the
holders of the Series A Preferred Stock in proportion to the aggregate
Liquidation Amount each such holder is otherwise entitled to receive. The
holders of Series A Preferred Stock shall have the right to convert such shares
into Common Stock, in accordance with Section 5 hereof, at any time prior to or
in connection with any liquidation, dissolution or winding up of the
Corporation.

               b. After payment to the holders of the Series A Preferred Stock
of the amounts set forth in Section 2.a. above, the entire remaining assets and
funds of the Corporation legally available for distribution, if any, to the
Corporation's stockholders shall be distributed among the holders of the Common
Stock and the Series A Preferred Stock in proportion to the shares of Common
Stock then held by them and the shares of Common Stock which they then have the
right to acquire upon conversion of the shares of Series A Preferred Stock then
held by them.


                                       2
<PAGE>   3


               c. For purposes of this Section 2, at the written direction of
holders of at least a majority of the shares of Series A Preferred Stock then
outstanding, (i) any acquisition of the Corporation by means of merger or other
form of corporate reorganization in which outstanding shares of the Corporation
are exchanged for securities or other consideration issued or paid, or caused to
be issued or paid, by the acquiring entity or its subsidiary (other than a mere
reincorporation transaction) or (ii) a sale, lease or conveyance of all or
substantially all of the assets of the Corporation (upon such written direction,
each event described in (i) and (ii), a "Corporate Transaction"), shall be
treated as a liquidation, dissolution or winding up of the Corporation and shall
entitle the holders of Series A Preferred Stock to receive at the closing of
such Corporate Transaction in cash, securities or other property (valued as
provided in Section 2.d. below) the amounts specified in Section 2.a. above. The
provisions of this Section 2 shall not apply to any reorganization, merger or
consolidation involving (1) only a change in the state of incorporation of the
Corporation, (2) a merger of the Corporation with or into a wholly-owned
subsidiary of the Corporation that is incorporated in the United States of
America, or (3) an acquisition by merger, reorganization or consolidation of
another corporation (a) in which the Corporation is substantively the surviving
corporation, the Corporation continues to operate thereafter as a going concern
and the Corporation is not the target in such acquisition, and (b) that (i) is
approved by the Board of Directors of the Corporation, (ii) does not result in
the holders of the Corporation's Common Stock and Preferred Stock immediately
prior thereto holding less than 50% of the outstanding voting securities of the
surviving corporation immediately thereafter and (iii) does not involve a
recapitalization of the Series A Preferred Stock.

               d. Whenever the distribution provided for in this Section 2 shall
be payable in securities or property other than cash, the value of such
distribution shall be the fair market value of such securities or other property
as determined in good faith by the Board of Directors. The Liquidation Amount
shall in all events be paid in cash; provided, however, that if the Liquidation
Amount is otherwise payable in connection with a consolidation or merger of the
Corporation, or sale of substantially all of the capital stock of the
Corporation, then each holder of the Series A Preferred Stock shall receive
payments with respect to the Series A Preferred Stock in the same form of
consideration as is payable with respect to the Common Stock. In the event of
any business combination or acquisition involving the Corporation which is
intended to be treated as a "pooling of interests" for accounting purposes under
Accounting Principles Board Opinion No. 16, the acquisition consideration
(including any shares of capital stock or other securities to be delivered or
exchanged by the acquiring corporation) shall be reallocated among the holders
of Series A Preferred Stock in an appropriate manner to give economic effect to
the essential intent and purposes of Sections 2.a and 2.c.

          3. Redemption.

               a. At any time after December 31, 2002, the holders of a majority
of the outstanding shares of Series A Preferred Stock shall have the option to
require the Corporation to redeem (a "Mandatory Redemption") all, but not less
than all, of the Series A Preferred Stock then outstanding at a price per share
of Series A Preferred Stock equal to the Liquidation Amount. The holders of
shares of Series A Preferred Stock may exercise such option by giving written
notice (the "Redemption Notice") to the Corporation of such election. Such
Mandatory Redemption shall be effected, and the Corporation shall be obligated
to redeem


                                       3
<PAGE>   4


all outstanding shares of Series A Preferred Stock, to the extent that it may
lawfully do so, in three equal annual installments each equal to one-third of
the number of shares of Series A Preferred Stock outstanding at the time such
option is exercised. The redemption dates for any such Mandatory Redemption
shall be the 45th day after receipt by the Corporation of such Redemption Notice
and the first and second anniversaries of such 45th day (each, a "Mandatory
Redemption Date").

               b. If the funds of the Corporation legally available for
redemption of Series A Preferred Stock on any Mandatory Redemption Date are
insufficient to redeem the total number of shares of Series A Preferred Stock to
be redeemed on such Mandatory Redemption Date, those funds that are legally
available shall be used to redeem the maximum possible number of shares of
Series A Preferred Stock ratably among the holders of such shares to be redeemed
on the basis of the redemption amounts due with respect to the shares held by
each such holder. At any time and from time to time thereafter when additional
funds of the Corporation are legally available for redemption of shares of
Series A Preferred Stock, such funds shall be used to immediately redeem the
balance of the shares which the Corporation has become obligated to redeem on
any Mandatory Redemption Date but which it has not redeemed. Such shares shall
be redeemed ratably among the holders of such shares to be redeemed on the basis
of the redemption amounts due with respect to the balance of the shares held by
each such holder which the Corporation became obligated to redeem on such
Mandatory Redemption Date but which have not been redeemed. Such funds shall not
be used for any other purpose, including the redemption of any shares of Series
A Preferred Stock which the Corporation is obligated to redeem on any subsequent
date.

          4. Voting Rights. Each holder of shares of Series A Preferred Stock
shall be entitled to the number of votes equal to the number of whole shares of
Common Stock into which such shares of Series A Preferred Stock could be
converted and shall have voting rights and powers equal to the voting rights and
powers of such Common Stock (except as otherwise expressly provided herein or as
required by law, voting together with the Common Stock as a single class) and
shall be entitled to notice of any stockholders' meeting in accordance with the
Bylaws of the Corporation and the Delaware General Corporation Law. Fractional
votes shall not, however, be permitted and any fractional voting rights
resulting from the above formula (after aggregating all shares into which shares
of Series A Preferred Stock held by each holder could be converted) shall be
rounded to the nearest whole number (with one-half being rounded upward). Such
determination of "whole shares" shall be based upon the aggregate number of
shares of Series A Preferred Stock held by each holder, and not upon each share
of Series A Preferred Stock so held by the holder. Each holder of Common Stock
shall be entitled to one vote for each share of Common Stock held. Except as
otherwise expressly provided in the Certificate of Incorporation, the holders of
shares of Series A Preferred Stock and Common Stock shall vote together (or
render written consents in lieu of a vote) as a single class on all matters
submitted to the stockholders of the Corporation.

          5. Conversion. The holders of the Series A Preferred Stock shall have
conversion rights as follows (the "Conversion Rights"):

               a. Right to Convert. Each share of Series A Preferred Stock shall
be convertible, at the option of the holder thereof, at any time at the office
of the Corporation or any


                                       4
<PAGE>   5


transfer agent for such stock, into such number of fully paid and nonassessable
shares of Common Stock as is determined by dividing $100.00 plus all accrued but
unpaid dividends and interest thereon by the conversion price applicable to such
share (the "Conversion Price"), determined as hereinafter provided, in effect on
the date the certificate is surrendered for conversion. The Conversion Price at
which shares of Common Stock shall be deliverable upon conversion of shares of
the Series A Preferred Stock initially shall be $4.65 per share of Common Stock.
Such initial Conversion Price shall be adjusted as hereinafter provided.

               b. Mechanics of Conversion. Before any holder of Series A
Preferred Stock shall be entitled to convert the same into shares of Common
Stock, such holder shall surrender the certificate or certificates therefor,
duly endorsed, at the office of the Corporation or of any transfer agent for
such stock, and shall give written notice to the Corporation at such office that
such holder elects to convert the same and shall state therein the name or names
in which such holder wishes the certificate or certificates for shares of Common
Stock to be issued. The Corporation shall, as soon as practicable thereafter,
issue and deliver at such office to such holder of Series A Preferred Stock, a
certificate or certificates for the number of shares of Common Stock to which
such holder shall be entitled as aforesaid. Such conversion shall be deemed to
have been made immediately prior to the close of business on the date of
surrender of the shares of Series A Preferred Stock to be converted, and the
person or persons entitled to receive the shares of Common Stock issuable upon
such conversion shall be treated for all purposes as the record holder or
holders of such shares of Common Stock on such date.

               c. Adjustments to Conversion Price for Certain Diluting Issues.

                    (i) Special Definitions. For purposes of this Section 5.c.,
the following definitions apply:

                         (1) "Options" shall mean rights, options, or warrants
to subscribe for, purchase or otherwise acquire either Common Stock or
Convertible Securities (defined below) other than any such right, option, or
warrants covered by Section 5.c.4(B) below.

                         (2) "Original Issue Date" shall mean the date on which
a share of Series A Preferred Stock was first issued.

                         (3) "Convertible Securities" shall mean any evidences
of indebtedness, shares (other than Common Stock and Series A Preferred Stock)
or other securities convertible into or exchangeable for Common Stock.

                         (4) "Additional Shares of Common Stock" shall mean all
shares of Common Stock issued (or, pursuant to Section 5.c.(iii), deemed to be
issued) by the Corporation after the Original Issue Date, other than shares of
Common Stock issued (or deemed issued):

                               (A) upon conversion of shares of Series A
Preferred Stock;


                                       5
<PAGE>   6


                               (B) to outside directors, officers, employees and
consultants pursuant to the Corporation's 1994 Equity Compensation Plan or
Employee Stock Purchase Plan or other employee stock plan (the "Employee
Stock"), provided that (i) the issuance of such shares is or has been approved
by a majority of the members of the Board of Directors or any duly constituted
committee thereof and (ii) the number of shares of Employee Stock does not
exceed an aggregate of 2,700,000 shares (as adjusted for any stock dividends,
combinations, splits or similar events) regardless of whether issued by the
Corporation prior to the date hereof;

                               (C) as a dividend or distribution on Series A
Preferred Stock; or

                               (D) for which adjustment of the Conversion Price
is made pursuant to Section 5.d.

                    (ii) No Adjustment of Conversion Price. Any provision herein
to the contrary notwithstanding, no adjustment in the Conversion Price shall be
made in respect of the issuance of Additional Shares of Common Stock unless the
consideration per share (determined pursuant to Section 5.c.(v) hereof) for an
Additional Share of Common Stock issued or deemed to be issued by the
Corporation is less than the Conversion Price in effect on the date of, and
immediately prior to such issue. In computing each adjusted Conversion Price,
the result shall be rounded to five decimal places, and such adjustment shall be
made separately in each instance, and in the event the adjustment therefrom
results in a change of the Conversion Price of less than $0.01, no adjustment to
the then Conversion Price shall be made, but the amount of said adjustment
calculated thereby shall be carried forward to successive occasions until such
adjustments in the aggregate equal or exceed $0.01.

                    (iii) Deemed Issue of Additional Shares of Common Stock. In
the event the Corporation at any time or from time to time after the Original
Issue Date shall issue any Options or Convertible Securities or shall fix a
record date for the determination of holders of any class of securities then
entitled to receive any such Options or Convertible Securities, then the maximum
number of shares (as set forth in the instrument relating thereto without regard
to any provisions contained therein designed to protect against dilution) of
Common Stock issuable upon the exercise of such Options or, in the case of
Convertible Securities and Options therefor, the conversion or exchange of such
Convertible Securities, shall be deemed to be Additional Shares of Common Stock
issued as of the time of such issue or, in case such a record date shall have
been fixed, as of the close of business on such record date, provided further
that in any such case in which Additional Shares of Common Stock are deemed to
be issued:

                         (1) no further adjustments in the Conversion Price
shall be made upon the subsequent issue of Convertible Securities or shares of
Common Stock upon the exercise of such Options or conversion or exchange of such
Convertible Securities;

                         (2) if such Options or Convertible Securities by their
terms provide, with the passage of time or otherwise, for any increase in the
consideration payable to the Corporation, or decrease in the number of shares of
Common Stock issuable, upon


                                       6
<PAGE>   7


the exercise, conversion or exchange thereof, the Conversion Price computed upon
the original issue thereof (or upon the occurrence of a record date with respect
thereto), and any subsequent adjustments based thereon, shall, upon any such
increase or decrease becoming effective, be recomputed to reflect such increase
or decrease insofar as it affects such Options or the rights of conversion or
exchange under such Convertible Securities (provided, however, that no such
adjustment of the Conversion Price shall affect Common Stock previously issued
upon conversion of the Series A Preferred Stock);

                         (3) no readjustment pursuant to clause (1) or (2) above
shall have the effect of increasing the Conversion Price to an amount which
exceeds the lower of (a) the Conversion Price on the original adjustment date,
or (b) the Conversion Price that would have resulted from any issuance of
Additional Shares of Common Stock between the original adjustment date and such
readjustment date.

                    (iv) Adjustment of Conversion Price Upon Issuance of
Additional Shares of Common Stock. In the event the Corporation, at any time
after the Original Issue Date, shall issue Additional Shares of Common Stock
(including Additional Shares of Common Stock deemed to be issued pursuant to
Section 5.c.(iii)) without consideration or for a consideration per share less
than the Conversion Price in effect on the date of and immediately prior to such
issue, then and in such event, the Conversion Price shall be reduced,
concurrently with such issue, to a price (calculated to the nearest cent)
determined by multiplying the Conversion Price by a fraction, the numerator of
which shall be the number of shares of Common Stock outstanding immediately
prior to such issue plus the number of shares of Common Stock which the
aggregate consideration received by the Corporation for the total number of
Additional Shares of Common Stock so issued would purchase at the Conversion
Price in effect immediately prior to such issuance, and the denominator of which
shall be the number of shares of Common Stock outstanding immediately prior to
such issue plus the number of such Additional Shares of Common Stock so issued.
For the purpose of the above calculation, the number of shares of Common Stock
outstanding immediately prior to such issue shall be calculated on a fully
diluted basis, as if all shares of Series A Preferred Stock and all Convertible
Securities had been fully converted into shares of Common Stock and any
outstanding Options or other Convertible Securities had been fully exercised
(and the resulting securities fully converted into shares of Common Stock, if so
convertible) as of such date. The provisions of this Section 5.c may be waived
in any instance (without the necessity of convening any meeting of stockholders
of the Corporation) upon the written approval of the holders of a majority of
the outstanding shares of Series A Preferred Stock.

                    (v) Determination of Consideration. For purposes of this
Section 5.c., the consideration received by the Corporation for the issue of any
Additional Shares of Common Stock shall be computed as follows:

                         (1) Cash and Property: Such consideration shall:

                               (A) insofar as it consists of cash, be computed
at the aggregate amount of cash received by the Corporation;


                                       7
<PAGE>   8


                               (B) insofar as it consists of property other than
cash, be computed at the fair value thereof at the time of such issue, as
determined in good faith by the Board of Directors; and

                               (C) in the event Additional Shares of Common
Stock are issued together with other shares or securities or other assets of the
Corporation for consideration which covers both, be the proportion of such
consideration so received in exchange for the Additional Shares of Common Stock,
computed as provided in clauses (A) and (B) above, as determined in good faith
by the Board of Directors.

                         (2) Options and Convertible Securities. The
consideration per share received by the Corporation for Additional Shares of
Common Stock deemed to have been issued pursuant to Section 5.c.(iii), relating
to Options and Convertible Securities shall be determined by dividing

                               (A) the total amount, if any, received or
receivable by the Corporation as consideration for the issue of such Options or
Convertible Securities, plus the minimum aggregate amount of additional
consideration (as set forth in the instruments relating thereto, without regard
to any provision contained therein designed to protect against dilution) payable
to the Corporation upon the exercise of such Options or the conversion or
exchange of such Convertible Securities, or in the case of Options for
Convertible Securities, the exercise of such Options for Convertible Securities
and the conversion or exchange of such Convertible Securities, by

                               (B) the maximum number of shares of Common Stock
(as set forth in the instruments relating thereto, without regard to any
provision contained therein designed to protect against the dilution) issuable
upon the exercise of such Options or conversion or exchange of such Convertible
Securities.

               d. Adjustments to Conversion Price for Stock Dividends and for
Combinations or Subdivisions of Common Stock. In the event that the Corporation
at any time or from time to time after the Original Issue Date shall effect a
(i) subdivision of the outstanding shares of Common Stock into a greater number
of shares of Common Stock (by stock dividend, stock split, reclassification or
otherwise), or (ii) combination or consolidation of the outstanding shares of
Common Stock into a lesser number of shares of Common Stock (by reclassification
or otherwise), then the Conversion Price in effect immediately prior to such
event shall, concurrently with the effectiveness of such event, be
proportionately decreased or increased, as appropriate. In the event that the
Corporation shall declare or pay, without consideration, any dividend on the
Common Stock payable in Common Stock or in any right to acquire Common Stock for
no consideration, then the Corporation shall be deemed to have subdivided the
outstanding shares of Common Stock by an amount of shares equal to the maximum
number of shares issuable through such dividend and/or upon exercise of such
rights to acquire Common Stock.

               e. Adjustments to Conversion Price for Reclassification and
Reorganization. If the Common Stock issuable upon conversion of the Series A
Preferred Stock shall be changed into the same or a different number of shares
of any other class or classes of


                                       8
<PAGE>   9


stock, whether by capital reorganization, reclassification or otherwise (other
than as provided for in Section 5.d. above or in connection with a Corporate
Transaction), the Conversion Price then in effect shall, concurrently with the
effectiveness of such reorganization or reclassification, be proportionately
adjusted so that the Series A Preferred Stock shall be convertible into, in lieu
of the number of shares of Common Stock which the holders would otherwise have
been entitled to receive, a number of shares of such other class or classes of
stock equivalent to the number of shares of Common Stock that would have been
subject to receipt by the holders upon conversion of the Series A Preferred
Stock immediately before that change.

               f. No Impairment. The Corporation shall not, by amendment of its
Certificate of Incorporation or the Certificate of Incorporation of any
Subsidiary (as hereinafter defined) through any reorganization, transfer of
assets, consolidation, merger, dissolution, issue or sale of securities or any
other voluntary action, avoid or seek to avoid the observance or performance of
any of the terms to be observed or performed hereunder by the Corporation or any
Subsidiary, but shall at all times in good faith assist in the carrying out of
all the provisions of this Section 5 and in the taking of all such action as may
be necessary or appropriate in order to protect the Conversion Rights of the
holders of the Series A Preferred Stock against impairment.

               g. Certificates as to Adjustments. Upon the occurrence of each
adjustment or readjustment of the Conversion Price pursuant to this Section 5,
the Corporation at its expense shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and prepare and furnish to each
holder of Series A Preferred Stock a certificate executed by the Corporation's
President or Chief Financial Officer setting forth such adjustment or
readjustment and showing in detail the facts upon which such adjustment or
readjustment is based. The Corporation shall, upon the written request at any
time of any holder of Series A Preferred Stock, furnish or cause to be furnished
to such holder a like certificate setting forth (i) such adjustments and
readjustments, (ii) the Conversion Price at the time in effect, and (iii) the
number of shares of Common Stock and the amount, if any, of other property which
at the time would be received upon the conversion of the Series A Preferred
Stock.

               h. Notices of Record Date. In the event that the Corporation
shall propose at any time to effect any reclassification or recapitalization, to
merge or consolidate with or into any other entity, or sell, lease or convey all
or substantially all of its assets, or to liquidate, dissolve or wind up, then,
in connection with each such event, the Corporation shall send to the holders of
Series A Preferred Stock: (1) at least 20 days prior written notice of the date
on which a record shall be taken for such event and specifying the date on which
such event shall occur; and (2) at least 20 days prior written notice of the
record date for determining rights to vote, if any, in respect of such event.

               i. Issue Taxes. The Corporation shall pay any and all issue and
other taxes that may be payable in respect of any issue or delivery of shares of
Common Stock on conversion of shares of Series A Preferred Stock pursuant
hereto; provided, however, that the Corporation shall not be obligated to pay
any transfer taxes resulting from any transfer requested by any holder in
connection with any such conversion.


                                       9
<PAGE>   10


               j. Reservation of Stock Issuable Upon Conversion. The Corporation
shall at all times reserve and keep available out of its authorized but unissued
shares of Common Stock, solely for the purpose of effecting the conversion of
the shares of the Series A Preferred Stock, such number of its shares of Common
Stock as shall from time to time be sufficient to effect the conversion of all
outstanding shares of the Series A Preferred Stock; and if at any time the
number of authorized but unissued shares of Common Stock shall not be sufficient
to effect the conversion of all then outstanding shares of the Series A
Preferred Stock, the Corporation shall take such corporate action as may, in the
opinion of its counsel, be necessary to increase its authorized but unissued
shares of Common Stock to such number of shares as shall be sufficient for such
purpose, including, without limitation, engaging in best efforts to obtain the
requisite stockholder approval of any necessary amendment to this Certificate of
Incorporation.

               k. Fractional Shares. No fractional share shall be issued upon
the conversion of any share or shares of Series A Preferred Stock. All shares of
Common Stock (including fractions thereof) issuable upon conversion of more than
one share of Series A Preferred Stock by a holder thereof shall be aggregated
for purposes of determining whether the conversion would result in the issuance
of any fractional share. If, after the aforementioned aggregation, the
conversion would result in the issuance of a fraction of a share of Common
Stock, the Corporation shall, in lieu of issuing any fractional share, pay the
holder otherwise entitled to such fraction a sum in cash equal to the fair
market value of such fraction on the date of conversion (as determined in good
faith by the Board of Directors).

               l. Notices. Any notice required by the provisions of this Section
5 to be given to the holders of shares of Series A Preferred Stock shall be
deemed given if deposited in the United States mail, postage prepaid, and
addressed to each holder of record at his address appearing on the books of the
Corporation.

               m. Option to Convert to Securities of Subsidiary. At the option
of any holder of Series A Preferred Stock, such holder shall have the right (but
not the obligation) to convert in the manner provided in this Section 5.m any
share of Series A Preferred Stock then held by it into fully paid and
nonassessable shares of the common stock ("Subsidiary Common Stock") of any
direct or indirect subsidiary of the Corporation more than 50% of the
outstanding voting securities of which are owned directly or indirectly by the
Corporation (each, a "Subsidiary"). Such right may be exercised by delivery to
the Corporation of the certificates representing the shares of Series A
Preferred Stock to be converted together with written notice of such exercise
specifying the applicable Subsidiary. The number of shares of Subsidiary Common
Stock into which any share of Series A Preferred Stock is convertible under
Section 5.m shall be equal to the quotient obtained by dividing the aggregate
Fair Market Value (and hereinafter defined) of the number of shares of Common
Stock into which a share of Series A Preferred Stock is then convertible under
Section 5.a above by the Fair Market Value of a share of Subsidiary Common
Stock. As used herein, the term "Fair Market Value" shall mean (a) as of any
date and with respect to a share of the Corporation's Common Stock, the average
of the closing prices of the Corporation's Common Stock on the NASDAQ National
Market (or such other quotation system or securities exchange upon which the
Corporation's Common Stock is then traded) as reported by the NASDAQ National
Market or such exchange or other quotation system for the consecutive 30-day
trading period immediately preceding such date, and (b) as of any date and with
respect to a share of Subsidiary Common Stock, the most recent price per


                                       10
<PAGE>   11


share at which shares of such Subsidiary Common Stock were issued and sold by
such Subsidiary in an arm's length transaction with an unaffiliated third party
(or if lower, the price per share in a transaction with an affiliate),
including, if applicable, the exercise price per share in any options, rights or
warrants to subscribe for or otherwise acquire Subsidiary Common Stock
("Subsidiary Options") or Subsidiary Convertible Securities (as hereinafter
defined) or the conversion price per share in any securities convertible into or
exchangeable for Subsidiary Common Stock ("Subsidiary Convertible Securities").
The Corporation shall take, and shall cause the related Subsidiary to take, all
actions necessary to issue any shares of Subsidiary Common Stock issuable under
this Section 5.m and to cause such shares to be duly authorized, validly issued,
fully paid and nonassessable, including, without limitation, amending such
Subsidiary's Certificate of Incorporation to increase the number of shares of
Subsidiary Common Stock issuable thereunder, if necessary, and pay, on the
holders behalf, any consideration required to accomplish the foregoing. The
Corporation shall notify each holder of shares of Series A Preferred Stock of
any sale of Subsidiary Common Stock, Subsidiary Options or Subsidiary
Convertible Securities by a Subsidiary at least fifteen business days before
such sale is consummated. Any such notice shall be in writing and shall describe
the securities to be issued and sold by such Subsidiary and the consideration to
be received by it in connection therewith.

          6. Restrictions and Limitations. So long as any shares of Series A
Preferred Stock remain outstanding, in addition to any other vote required by
the Delaware General Corporation Law, the vote or written consent or written
agreement of the holders of at least a majority of the then outstanding shares
of the Series A Preferred Stock, voting as a separate class, shall be required
in order to:

                    (i)  alter, amend or modify the rights, preferences or
privileges of the Series A Preferred Stock;

                    (ii) increase the authorized number of shares of the Series
A Preferred Stock or issue any additional shares of Series A Preferred Stock
other than shares issued in payment of dividends on the outstanding share of
Series A Preferred Stock pursuant to Section 1.a above;

                    (iii) authorize or issue, or obligate itself to issue, any
other equity security (including any security convertible into or exercisable
for any equity security) senior to or on a parity with the Series A Preferred
Stock as to dividend rights, liquidation preferences or redemption rights;

                    (iv) redeem, purchase or otherwise acquire any shares of
Common Stock or Preferred Stock (or pay into a sinking fund for such purpose);
provided, however, that this restriction shall not apply to any redemption
pursuant to Section 3 or to the repurchase of shares of Common Stock at the
original purchase price from employees, officers, directors or other persons
performing services for this Corporation;

                    (v)  merge or consolidate with or into any other entity or
sell, lease or convey any substantial portion of the Corporation's assets,
provided, however, that the provisions of this clause (v) shall not apply to any
reorganization, merger or consolidation


                                       11
<PAGE>   12


involving (1) only a change in the state of incorporation of the Corporation,
(2) a merger of the Corporation with or into a wholly-owned subsidiary of the
Corporation that is incorporated in the United States of America, or (3) an
acquisition by merger, reorganization or consolidation of another corporation
(a) in which the Corporation is substantively the surviving corporation, the
Corporation continues to operate thereafter as a going concern and the
Corporation is not the target in such acquisition, and (b) that (i) is approved
by the Board of Directors of the Corporation, (ii) does not result in the
holders of the Corporation's Common Stock and Preferred Stock immediately prior
thereto holding less than 50% of the outstanding voting securities of the
surviving corporation immediately thereafter and (iii) does not involve a
recapitalization of the Series A Preferred Stock.;

                    (vi) alter, amend or modify the Corporation's Certificate of
Incorporation or Bylaws; or

                    (vii) amend or modify any existing employee incentive stock
plan of the Corporation to increase the number of shares of Common Stock
issuable thereunder, or create any new employee incentive stock plan for
employees, officers, directors or consultants of the Corporation.

          7. No Reissuance of Series A Preferred Stock. No share or shares of
Series A Preferred Stock acquired by the Corporation by reason of redemption,
purchase, conversion or otherwise shall be reissued, and all such shares shall
be cancelled, retired and restored to the status of undesignated Preferred
Stock.

     IN WITNESS WHEREOF, this Certificate of Designation has been signed by the
Chief Financial Officer of the Corporation this 6th day of August, 1999.

                            STOCK PURCHASE AGREEMENT


     THIS STOCK PURCHASE AGREEMENT is made as of the 6th day of August, 1999, by
and among USDATA Corporation, a Delaware corporation (the "Company"), and
Safeguard Delaware, Inc. (the "Investor").

     THE PARTIES HEREBY AGREE AS FOLLOWS:

     1.   Purchase and Sale of Stock.


     1.1  Sale and Issuance of Stock.

     (a) The Company shall adopt and file with the Secretary of State of
Delaware on or before the Closing (as defined below) a Certificate of
Designation for Series A Preferred Stock in the form attached hereto as Exhibit
A (the "Certificate").

     (b) Subject to the terms and conditions of this Agreement, the Investor
agrees to purchase at the Closing, and the Company agrees to sell and issue to
the Investor at the Closing, that number of shares of the Company's Series A
Preferred Stock, par value $0.01 per share (the "Series A Preferred Stock"), set
forth opposite the Investor's name on Schedule A hereto at an aggregate purchase
price of $5,000,000. The rights, privileges and preferences of the Series A
Preferred Stock shall be as stated in the Certificate.

     (c) Subject to the terms and conditions of this Agreement, the Investor
agrees to purchase at the Closing, and the Company agrees to sell and issue to
the Investor at the Closing, that number of shares of the Company's Common
Stock, par value $0.01 per share (the "Common Stock"), set forth opposite the
Investor's name on Schedule A hereto at an aggregate purchase price of
$5,000,000.

     1.2 Closing. The purchase and sale of the Series A Preferred Stock and the
Common Stock to be issued and sold hereunder (collectively, the "Stock") shall
take place at 10:00 a.m., central time, on August 6, 1999, or at such other time
as the Company and the Investor mutually agree upon (which time is designated as
the "Closing").

     1.3 Consideration. At the Closing, the Company shall deliver to the
Investor certificates representing the Stock being sold hereunder against
payment of the purchase price therefor by wire transfer.

     2. Representations and Warranties of the Company. The Company hereby
represents and warrants to the Investor that, except as set forth on the
Disclosure Schedule attached hereto as Schedule B (the "Disclosure Schedule")
furnished to the Investor and its special counsel, which exceptions shall be
deemed to be representations and warranties as if made hereunder:

     2.1 Organization, Good Standing and Qualification. Each of the Company and
each of its subsidiaries is a corporation duly organized, validly existing and
in good standing under the laws of the state of its formation and has all
requisite corporate power and authority to


<PAGE>   5

carry on its business as now conducted and as proposed to be conducted. Each of
the Company and each of its subsidiaries is duly qualified to transact business
and is in good standing in each jurisdiction in which the failure to so qualify
would have a material adverse effect on its business, properties, results of
operation or financial condition.

     2.2 SEC Reports; Financial Statements. The Common Stock, par value $0.01
per share, of the Company is registered under Section 12(b) or (g) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the
Company is in full compliance with its reporting and filing obligations under
the Exchange Act. The Company has delivered to the Investor (a) its annual
reports to stockholders and its Annual Reports on Form 10-K for its last two
fiscal years and (b) all of its Quarterly Reports on Form 10-Q and each other
report, registration statement or definitive proxy statement filed with the
Securities and Exchange Commission (the "SEC") since the beginning of such two
fiscal years (collectively, the "SEC Reports"). The SEC Reports (other than
Quarterly Reports on Form 10-Q filed prior to the latest Annual Report on Form
10-K filed by the Company) do not (as of their respective dates) contain any
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary to make the statements therein, in the light of
the circumstances under which they were made, not misleading. The audited and
unaudited financial statements of the Company included in the SEC Reports (the
"Financial Statements") have been prepared in accordance with generally accepted
accounting principles applied on a consistent basis (except as stated in such
Financial Statements or the notes thereto) and fairly present the financial
position of the Company and its consolidated subsidiaries as of the dates
thereof and the results of their operations and changes in financial position
for the periods then ended. Except as disclosed by the Company in the SEC
Reports, since the end of the most recent of such fiscal years, there has been
no material adverse change in the business, properties, financial condition or
results of operations of the Company and its subsidiaries taken together, and
there is no existing condition, event or series of events which reasonably would
be expected to have a material adverse effect on the business, properties,
financial condition or results of operations of the Company and its subsidiaries
taken together, or the ability of the Company to perform its obligations under
this Agreement or the Investors' Rights Agreement (as defined below).

     2.3 Capitalization and Voting Rights

     (a) The authorized capital of the Company consists of:

The execution, delivery and performance of this Agreement and the Investors'
Rights Agreement and the consummation of the transactions contemplated hereby
and thereby will not result in any such violation or be in conflict with or
constitute, with or without the passage of time and giving of notice, either a
default under any such provision, agreement, instrument, contract, document,

results in the creation of any lien, charge or encumbrance upon any assets of
the Company or any of its subsidiaries or the suspension, revocation,

authorization, or approval applicable to the Company or any of its subsidiaries,

     3. Representations and Warranties of the Investor. The Investor hereby
represents and warrants that:

     3.1 Authorization. The Investor has full power and authority to enter into
this Agreement and the Investors' Rights Agreement, and each such Agreement
constitutes its valid and legally binding obligation, enforceable in accordance
with its terms.

     3.2 Purchase Entirely for Own Account. This Agreement is made with the
Investor in reliance upon the Investor's representation to the Company, which by
the Investor's execution of this Agreement the Investor hereby confirms, that
the Stock to be received by the Investor and the Common Stock issuable upon
conversion of the Series A Preferred Stock will be acquired for investment for
the Investor's own account, not as a nominee or agent, and not with a view to
the resale or distribution of any part thereof, and that the Investor has no
present intention of selling, granting any participation in, or otherwise
distributing the same. By executing this Agreement, the Investor further
represents that the Investor does not have any contract, undertaking, agreement
or arrangement with any person to sell, transfer or grant participations to such
person or to any third person, with respect to any of the Stock or Common Stock
issuable upon conversion of the Series A Preferred Stock.

     3.3 Disclosure of Information. The Investor believes it has received all
the information it considers necessary or appropriate for deciding whether to
purchase the Stock. The Investor further represents that it has had an
opportunity to ask questions and receive answers from the Company regarding the
terms and conditions of the offering of the Stock and the business, properties,
prospects and financial condition of the Company. The foregoing, however, does
not limit or modify the representations and warranties of the Company in Section
2 of this Agreement or the right of the Investor to rely thereon.

                                       4
<PAGE>   8

     3.4 Investment Experience. The Investor is an investor in securities of
companies in the development stage and acknowledges that it is able to fend for
itself, can bear the economic risk of its investment, and has such knowledge and
experience in financial or business matters that it is capable of evaluating the
merits and risks of the investment in the Stock. The Investor also represents it
has not been organized for the purpose of acquiring the Stock.

     3.5 Accredited Investor. The Investor is an "accredited investor" within
the meaning of SEC Rule 501 of Regulation D, as presently in effect.

     3.6 Restricted Securities. The Investor understands that the shares of
Stock it is purchasing are characterized as "restricted securities" under the
federal securities laws inasmuch as they are being acquired from the Company in
a transaction not involving a public offering and that under such laws and
applicable regulations such securities may be resold without registration under
the Act, only in certain limited circumstances. In this connection, the Investor
represents that it is familiar with SEC Rule 144, as presently in effect, and
understands the resale limitations imposed thereby and by the Act.

     3.7 Further Limitations on Disposition. Without in any way limiting the
representations set forth above, the Investor further agrees not to make any
disposition of all or any portion of the Stock or Common Stock issuable upon
conversion of the Series A Preferred Stock unless and until the transferee has
agreed in writing for the benefit of the Company to be bound by this Section 3
and the Investors' Rights Agreement, and:

     (a) There is then in effect a Registration Statement under the Act covering
such proposed disposition and such disposition is made in accordance with such
Registration Statement; or

     (b) If reasonably requested by the Company, the Investor shall have
furnished the Company with an opinion of counsel, reasonably satisfactory to the
Company that such disposition will not require registration of such shares under
the Act.

     3.8 Legends. It is understood that the certificates evidencing the Stock or
Common Stock issuable upon conversion of the Series A Preferred Stock may bear
one or all of the following legends:

     (a) "These securities have not been registered under the Securities Act of
1933, as amended. They may not be sold, offered for sale, pledged or
hypothecated in the absence of a registration statement in effect with respect
to the securities under such Act or an opinion of counsel satisfactory to the
Company that such registration is not required or unless sold pursuant to Rule
144 of such Act."

     (h) Any legend required by the securities laws of any applicable
jurisdictions.

     (c) Any legend required by the Investors' Rights Agreement or other
applicable agreement.

(or such period as the parties shall otherwise agree) following the date of
notification (the "Notice Date") by one party to the other(s) of the existence
of such Dispute, then any such Dispute shall be resolved in the following
manner.

<PAGE>   12

     (c) Any action, suit or proceeding where the amount in controversy as to at
least one party, exclusive of interest and costs, exceeds $100,000 ("Summary
Proceeding"), arising out of or relating to a Dispute which has not been

(the "Delaware Superior Court") as a summary proceeding pursuant to Rules

unconditionally (A) submits to the jurisdiction of the Delaware Superior Court
for any Summary Proceeding, (B) agrees not to commence any Summary Proceeding
except in the Delaware Superior Court, (C) waives, and agrees not to plead or to
make, any objection to the venue of any Summary Proceeding in the Delaware
Superior Court, (D) waives, and agrees not to plead or to make any claim that
any Summary Proceeding brought in the Delaware Superior Court has been brought
in an improper or otherwise inconvenient forum, (E) waives, and agrees not to
plead or to make, any claim that the Delaware Superior Court lacks personal

controversy as to at least one party, exclusive of interest and costs, does not
exceed $100,000 (a "Proceeding"), arising out of or relating to a Dispute is
brought, the parties to such Proceeding agree to make application to the
Delaware Superior Court to proceed under the Summary Proceeding Rules. Until
such time as such application is rejected, such Proceeding shall be treated as a
Summary Proceeding and all of the foregoing provisions of Section 6.10(c)
relating to Summary Proceedings shall apply to such Proceeding.

     (e) If a Summary Proceeding is not available to resolve any Dispute
hereunder, the controversy or claim shall be settled by arbitration conducted on
a confidential basis, under the U.S. Arbitration Act, if applicable, and the
then current Commercial Arbitration Rules of the American Arbitration
Association (the "Association") strictly in accordance with the terms of this
Agreement and the substantive law of the State of Delaware including law in
respect of any statute of limitations. The arbitration shall be conducted at the
Association's regional office located in Philadelphia, Pennsylvania by three
arbitrators, at least one of whom shall be knowledgeable in telecommunications,
one of whom shall be an attorney and one of whom shall be a member of a "Big
Five" accounting firm familiar with telecommunications. Absent mutual agreement
of the parties, the arbitrators specified in the preceding sentence shall be
appointed pursuant to the Commercial Arbitration Rules of the Association. The
arbitrators are not empowered to award damages in excess of compensatory damages
and each party hereby irrevocably waives any right to recover damages in excess
of compensatory damages with respect to any such Dispute. Judgment upon the
arbitrators' award may be entered and enforced in any court of competent
jurisdiction.

     (f) Neither party shall be precluded hereby from securing equitable
remedies in courts of any jurisdiction, including, but not limited to, temporary
restraining orders and preliminary injunctions to protect its rights and
interests but shall not be sought as a means to avoid or stay arbitration or
Summary Proceeding.

                                       9
<PAGE>   13

this contract pending final resolution of any Dispute, unless to do so would be
impossible or impracticable under the circumstances.

the observance of any term of this Agreement may be waived (either generally or
in a particular instance and either retroactively or prospectively), only with
the written consent of the Company, the holders of a majority of the Common
Stock issued or issuable upon conversion of the Series A Preferred Stock issued
hereunder and the holders of a majority of the Common Stock issued hereunder.
Any amendment or waiver effected in accordance with this paragraph shall be
binding upon each holder of any securities purchased under this Agreement at the
time outstanding (including securities into which such securities are
convertible), each future holder of all such securities, and the Company.

     6.12 Severability. If one or more provisions of this Agreement are held to
be unenforceable under applicable law, such provision shall be excluded from
this Agreement and the balance of the Agreement shall be interpreted as if such
provision were so excluded and shall be enforceable in accordance with its
terms.

     6.13 Aggregation of Stock. All shares of the Stock held or acquired by
affiliated entities or persons shall be aggregated together for the purpose of
determining the availability of any rights under this Agreement.

     6.14 Publicity. Neither the Company nor the Investor shall take any action,
or permit any of its employees, consultants, officers, directors or stockholders
to take any action, which may result in the public disclosure of the
transactions effected hereby or the identity of the Investor, unless required by
law. If the Company determines that it is required by law to disclose these
transactions or the identity of the Investor, it shall, at a reasonable time
before making any such disclosure, consult with each Investor regarding such
disclosure and seek confidential treatment of this Agreement and all schedules
and exhibits hereto.

     6.15 Entire Agreement. This Agreement and the documents referred to herein
constitute the entire agreement among the parties and no party shall be liable
or bound to any other party in any manner by any warranties, representations, or
covenants except as specifically set forth herein or therein.

     NOW, THEREFORE, in consideration of the foregoing and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows:

distribution with respect to, or in exchange for or in replacement of such
shares of Common Stock;

     (f) the number of shares of "Registrable Securities then outstanding" shall

the SEC, and all amendments and supplements to such registration statement,
including post-effective amendments, in each case, including the prospectus
contained therein, all exhibits thereto and all documents incorporated or deemed
to be incorporated by reference therein.

     1.2 SHELF REGISTRATION.

     (a) The Company shall prepare and, not later than the first anniversary of
the date hereof, shall file with the SEC a Shelf Registration Statement with
respect to resales of the Registrable Securities from time to time in accordance
with the methods of distribution elected by the Holders of the Registrable
Securities and set forth in such Shelf Registration Statement and thereafter
shall use its best efforts to cause such Shelf Registration Statement to be
declared effective under the Act prior to the first anniversary of the date
hereof. The Company shall supplement or amend the Shelf Registration Statement
if required by the rules, regulations or instructions applicable to the
registration form used by the Company for the Shelf Registration Statement, if
required by the Act, the 1934 Act or the SEC.

     (b) The Company shall keep the Shelf Registration Statement continuously
effective under the Act in order to permit the prospectus forming a part thereof
to be usable by all Holders until the earliest of (i) the fifth anniversary of
the date hereof, (ii) the date as of which all Registrable Securities have been
transferred pursuant to Rule 144 under the Securities Act (or any similar
provision then in force), and (iii) such date as of which all Registrable
Securities have been sold pursuant to the Shelf Registration Statement (in any
such case, such period being called the "Shelf Registration Period"). The
Company shall: (i) subject to Section 1.2(c), prepare and file with the SEC such
amendments and post-effective amendments to the Shelf



                                        2
<PAGE>   6

Registration Statement as may be necessary to keep the Shelf Registration
Statement continuously effective for the Shelf Registration Period; (ii) subject
to Section 1.2(c), cause the related prospectus to be supplemented by any
required supplement, and as so supplemented to be filed pursuant to Rule 424 (or
any similar provisions then in force) under the Act; and (iii) comply in all
material respects with the provisions of the Act with respect to the disposition
of all securities covered by the Shelf Registration Statement during the
applicable period in accordance with the intended methods of disposition by the
sellers thereof set forth in such Shelf Registration Statement as so amended or
such prospectus as so supplemented.

     (c) The Company may suspend the use of the prospectus forming a part of the
Shelf Registration Statement for two periods not to exceed an aggregate of 60
days in any twelve-month period for valid business reasons, to be determined by
the Company in its reasonable judgment (not including avoidance of the Company's
obligations hereunder), including, without limitation, the acquisition or
divestiture of assets, public filings with the SEC, pending corporate
developments and similar events. The Company shall provide written notice to the
Holders of any such suspension.

     1.3 COMPANY REGISTRATION. If (but without any obligation to do so) the
Company proposes to register (including for this purpose a registration effected
by the Company for stockholders other than the Holders) any securities under the
Act in connection with the public offering of such securities solely for cash
(other than a registration relating solely to the sale of securities to
participants in a Company stock plan, a registration on Form S-4 (or its
successor) relating to an offering of shares in connection with any acquisition
of any entity or business, a registration on any form which does not include
substantially the same information as would be required to be included in a
registration statement covering the sale of the Registrable Securities or a
registration in which the only Common Stock being registered is Common Stock
issuable upon conversion of debt securities or exercise of warrants which are
also being registered) and the Registrable Securities have not theretofore been
included in a Shelf Registration Statement pursuant to Section 1.2 that remains
effective, the Company shall, at such time, promptly give each Holder written
notice of such registration. Upon the written request of each Holder given
within 20 days after mailing of such notice by the Company, the Company shall,
subject to the provisions of Section 1.8, cause to be registered under the Act
all of the Registrable Securities that each such Holder has requested to be
registered. The obligations of the Company under this Section 1.3 with respect
to any particular offering may be waived at any time upon the written consent of
Holders a majority of the outstanding Registrable Securities. The right of any
Holder to request inclusion of Registrable Securities held by it in any
registration pursuant to this Section 1.3 shall terminate if all shares of
Registrable Securities held or entitled to be held upon conversion by such
Holder are eligible to be sold under Rule 144 under the Act during any 90-day
period. In any event, such right shall terminate on the fifth anniversary of the
date hereof.

     1.4 OBLIGATIONS OF THE COMPANY. Whenever required under this Section 1 to
effect the registration of any Registrable Securities, the Company shall, as
expeditiously as reasonably possible:

     (a) prepare and file with the SEC a registration statement with respect to
such Registrable Securities and use its best efforts to cause such registration
statement to become


                                        3
<PAGE>   7

effective, and in the case of a registration under Section 1.3 or 1.14 hereof,
upon the request of the Holders of a majority of the Registrable Securities
registered thereunder, keep such registration statement effective for a period
of up to 120 days or, if earlier, until the distribution contemplated in such
registration statement has been completed; provided, however, that such 120-day
period shall be extended for a period of time equal to the period the Holder
refrains from selling any securities included in such registration at the
request of an underwriter of Common Stock (or other securities) of the Company;

     (b) prepare and file with the SEC such amendments and supplements to such
registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
Act with respect to the disposition of all securities covered by such
registration statement;

     (c) furnish to the Holders such numbers of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
Act, and such other documents as they may reasonably request in order to
facilitate the disposition of Registrable Securities owned by them;

     (d) use its best efforts to register and qualify the securities covered by
such registration statement under such other securities or Blue Sky laws of such
jurisdictions as shall be reasonably requested by the Holders; provided,
however, that the Company shall not be required in connection therewith or as a
condition thereto to qualify to do business or to file a general consent to
service of process in any such states or jurisdictions in which it is not, at
the time, so qualified or otherwise subject itself to general taxation in any
such states or jurisdictions;

     (e) in the event of any underwritten public offering, enter into and
perform its obligations under an underwriting agreement, in usual and customary
form, with the managing underwriter of such offering, it being understood and
agreed that each Holder participating in such underwriting shall also enter into
and perform its obligations under such an agreement;

     (f) notify each Holder of Registrable Securities covered by such
registration statement in writing at any time when a prospectus relating thereto
is required to be delivered under the Act of the happening of any event as a
result of which the prospectus included in such registration statement, as then
in effect, includes an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading in the light of the circumstances then existing;

     (g) cause all such Registrable Securities registered pursuant hereunder to
be listed on each securities exchange on which similar securities issued by the
Company are then listed;

     (h) provide a transfer agent and registrar for all Registrable Securities
registered pursuant hereunder and a CUSIP number for all such Registrable
Securities, in each case not later than the effective date of such registration;

     (i) use its best efforts to obtain the withdrawal of any order suspending
the effectiveness of any such registration statement or the lifting of any
suspension of the

                                        4
<PAGE>   8

qualification (or exemption from qualification) of any of the Registrable
Securities for offer or sale in any jurisdiction at the earliest possible time;
and

     (j) cooperate in all necessary respects with (A) counsel in preparation of
the customary legal opinions and (B) accountants in preparation of the customary
comfort letters.

     1.5 FURNISH INFORMATION. It shall be a condition precedent to the
obligations of the Company to take any action pursuant to this Section 1 with
respect to the Registrable Securities of any selling Holder that such Holder
shall furnish to the Company such information regarding itself, the Registrable
Securities held by it, and the intended method of disposition of such securities
as shall be required to effect the registration of such Holder's Registrable
Securities.

     1.6 EXPENSES OF SHELF REGISTRATION. All expenses other than underwriting
discounts and commissions incurred in connection with registrations, filings or
qualifications pursuant to Section 1.2, including (without limitation) all
registration, filing and qualification fees, printers' and accounting fees, fees
and disbursements of counsel for the Company and the reasonable fees and
disbursements, which shall not exceed $25,000, of one counsel for the selling
Holders (to be selected by the Holders holding a majority of the Registrable
Securities) shall be borne and paid by the Company.

     1.7 EXPENSES OF COMPANY REGISTRATION. The Company shall bear and pay all
expenses incurred in connection with any registration, filing or qualification
of Registrable Securities with respect to the registrations pursuant to Section
1.3 for each Holder (which right may be assigned as provided in Section 1.13),
including (without limitation) all registration, filing, and qualification fees,
printers and accounting fees relating or apportionable thereto and the fees and
disbursements, which shall not exceed $25,000, of one counsel for the selling
Holders (to be selected by the holders of a majority of the Registrable
Securities to be registered), but excluding underwriting discounts and
commissions relating to Registrable Securities.

     1.8 UNDERWRITING REQUIREMENTS. In connection with any offering involving an
underwriting of shares of the Company's capital stock under Section 1.3, the
Company shall not be required to include any of the Holders' securities in such
underwriting unless they accept the terms of the underwriting as agreed upon
between the Company and the underwriters selected by it (or by other persons
entitled to select the underwriters), and then only in such quantity as the
underwriters determine in their sole discretion will not, jeopardize the success
of the offering by the Company. If the total amount of securities, including
Registrable Securities, requested by stockholders to be included in such
offering exceeds the amount of securities sold other than by the Company that
the underwriters determine in their sole discretion is compatible with the
success of the offering, then the Company shall be required to include in the
offering only that number of such securities, including Registrable Securities,
which the underwriters determine in their sole discretion will not jeopardize
the success of the offering. The securities so included shall be apportioned (a)
first to Holders selling Registrable Securities pro rata according to the total
amount of Registrable Securities entitled to be included therein owned by each
selling Holder and (b) second, to the extent determined by the underwriters to
be compatible with the offering, to other stockholders.

                                        5
<PAGE>   9

     1.9 DELAY OF REGISTRATION. No Holder shall have any right to obtain or seek
an injunction restraining or otherwise delaying any such registration as the
result of any controversy that might arise with respect to the interpretation or
implementation of this Section 1.

     1.10 INDEMNIFICATION. In the event any Registrable Securities are included
in a registration statement under this Section 1:

     (a) to the extent permitted by law, the Company will indemnify and hold
harmless each Holder, any underwriter (as defined in the Act) for such Holder
and each person, if any, who controls such Holder or underwriter within the
meaning of the Act or the 1934 Act, against any losses, claims, damages, or
liabilities (joint or several) to which they may become subject under the Act,
the 1934 Act or other federal or state law, insofar as such losses, claims,
damages, or liabilities (or actions in respect thereof) arise out of or are
based upon any of the following statements, omissions or violations
(collectively a "Violation"): (i) any untrue statement or alleged untrue
statement of a material fact contained in such registration statement, including
any preliminary prospectus or final prospectus contained therein or any
amendments or supplements thereto, (ii) the omission or alleged omission to
state therein a material fact required to be stated therein, or necessary to
make the statements therein not misleading, or (iii) any violation or alleged
violation by the Company of the Act, the 1934 Act, any state securities law or
any rule or regulation promulgated under the Act, the 1934 Act or any state
securities law; and the Company will pay to each such Holder, underwriter or
controlling person, as incurred, any legal or other expenses reasonably incurred
by them in connection with investigating or defending any such loss, claim,
damage, liability, or action; provided, however, that the indemnity agreement
contained in this subsection 1.10(a) shall not apply to: (x) amounts paid in
settlement of any such loss, claim, damage, liability, or action if such
settlement is effected without the consent of the Company (which consent shall
not be unreasonably withheld); (y) any such loss, claim, damage, liability, or
action to the extent that it arises out of or is based upon a Violation which
occurs in reliance upon and in conformity with written information furnished
expressly for use in connection with such registration by any such Holder,
underwriter or controlling person; (z) any such loss, claim, damage, liability
or action to the extent that it arises out of or is based upon such Holder's or
underwriter's failure to deliver a copy of the registration statement or
prospectus or any amendments or supplements thereto;

     (b) to the extent permitted by law, each selling Holder will indemnify and
hold harmless the Company, each of its directors, each of its officers who has
signed the registration statement, each person, if any, who controls the Company
within the meaning of the Act, any underwriter, any other Holder selling
securities in such registration statement and any controlling person of any such
underwriter or other Holder, against any losses, claims, damages, or liabilities
(joint or several) to which any of the foregoing persons may become subject,
under the Act, the 1934 Act or other federal or state law, insofar as such
losses, claims, damages, or liabilities (or actions in respect thereto) arise
out of or are based upon any Violation, in each case to the extent (and only to
the extent) that such Violation occurs in reliance upon and in conformity with
written information furnished by such Holder expressly for use in connection
with such registration; and each such Holder will pay, as incurred, any legal or
other expenses reasonably incurred by any person intended to be indemnified
pursuant to this subsection 1.10(b), in connection with investigating or
defending any such loss, claim, damage, liability, or


                                        6
<PAGE>   10
action; provided, however, that the indemnity agreement contained in this
subsection 1.10(b) shall not apply to amounts paid in settlement of any such
loss, claim, damage, liability or action if such settlement is effected without
the consent of the Holder, which consent shall not be unreasonably withheld;
provided, that, in no event shall any indemnity under this subsection 1.10(b)
exceed the gross proceeds from the offering received by such Holder;

     (c) promptly after receipt by an indemnified party under this Section 1.10
of notice of the commencement of any action (including any governmental action),
such indemnified party will, if a claim in respect thereof is to be made against
any indemnifying party under this Section 1.10, deliver to the indemnifying
party a written notice of the commencement thereof and the indemnifying party
shall have the right to participate in, and, to the extent the indemnifying
party so desires, jointly with any other indemnifying party similarly noticed,
to assume the defense thereof with counsel mutually satisfactory to the parties;
provided, however, that an indemnified party (together with all other
indemnified parties which may be represented without conflict by one counsel)
shall have the right to retain one separate counsel, with the fees and expenses
to be paid by the indemnifying party, if representation of such indemnified
party by the counsel retained by the indemnifying party would be inappropriate
due to actual or potential differing interests between such indemnified party
and any other party represented by such counsel in such proceeding. The failure
to deliver written notice to the indemnifying party within a reasonable time of
the commencement of any such action, if prejudicial to its ability to defend
such action, shall relieve such indemnifying party of any liability to the
indemnified party under this Section 1.10, but the omission so to deliver
written notice to the indemnifying party will not relieve it of any liability
that it may have to any indemnified party otherwise than under this Section
1.10;

     (d) if the indemnification provided for in this Section 1.10 is held by a
court of competent jurisdiction to be unavailable to an indemnified party with
respect to any loss, liability, claim, damage, or expense referred to therein,
then the indemnifying party, in lieu of indemnifying such indemnified party
hereunder, shall contribute to the amount paid or payable by such indemnified
party as a result of such loss, liability, claim, damage, or expense in such
proportion as is appropriate to reflect the relative fault of the indemnifying
party on the one hand and of the indemnified party on the other in connection
with the statements or omissions that resulted in such loss, liability, claim,
damage, or expense as well as any other relevant equitable considerations. The
relative fault of the indemnifying party and of the indemnified party shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission to state a material fact
relates to information supplied by the indemnifying party or by the indemnified
party and the parties' relative intent, knowledge, access to information, and
opportunity to correct or prevent such statement or omission. In no event shall
any contribution by a Holder under this subsection 1.10(d) exceed the gross
proceeds from the offering received by such Holder. In no event shall a person
or entity guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Act) be entitled to contribution from any person or entity who was
not guilty of fraudulent misrepresentation;

     (e) notwithstanding the foregoing, to the extent that the provisions on
indemnification and contribution contained in the underwriting agreement entered
into in connection with the underwritten public offering are in conflict with
the foregoing provisions, the provisions in the underwriting agreement shall
control; and

                                        7
<PAGE>   11

     (f) the obligations of the Company and Holders under this Section 1.10
shall survive the completion of any offering of Registrable Securities in a
registration statement under this Section 1, and otherwise.

     1.11 REPORTS UNDER SECURITIES EXCHANGE ACT OF 1934. The Company shall cause
its Common Stock to continue to be registered under Sections 12(b) or 12(g) of
the 1934 Act, shall comply in all respects with its reporting and filing
obligations under the 1934 Act, and shall not take any action or file any
document (whether or not permitted by the 1934 Act or the rules thereunder) to
terminate or suspend such registration or to terminate or suspend its reporting
and filing obligations under the 1934 Act. The Company shall take all action
necessary to continue the listing or trading of its Common Stock on any national
securities exchange or the Automated Quotation System of the National
Association of Securities Dealers on which Common Stock is listed or traded, and
shall comply in all respects with its reporting, filing and other obligations
under the bylaws or rules of such exchange or association. The Company will
furnish to any Holder, so long as the Holder owns any Registrable Securities,
forthwith upon request (i) a written statement by the Company that it has
complied with the reporting requirements of SEC Rule 144, the Act and the 1934
Act or that it qualifies as a registrant whose securities may be resold pursuant
to Form S-3 under the Act, (ii) a copy of the most recent annual or quarterly
report of the Company and such other reports and documents as are filed by the
Company under the 1934 Act, and (iii) such other information as may be
reasonably requested in availing any Holder of any rule or regulation of the SEC
which permits the selling of any such securities without registration or
pursuant to such form.

     1.12 ASSIGNMENT OF REGISTRATION RIGHTS. The rights to cause the Company to
register Registrable Securities pursuant to this Section 1 may be assigned (but
only with all related obligations) by a Holder to (a) any partner or retired
partner of any holder which is a partnership, (b) any family member or trust for
the benefit of any individual holder, or (c) any transferee or assignee who,
after such assignment or transfer, holds at least 15% of the then outstanding
Registrable Securities, provided: (i) the Company is, within a reasonable time
after such transfer, furnished with written notice of the name and address of
such transferee or assignee and the securities with respect to which such
registration rights are being assigned; (ii) such transferee or assignee agrees
in writing to be bound by and subject to the terms and conditions of this
Agreement; and (iii) such assignment shall be effective only if immediately
following such transfer the further disposition of such securities by the
transferee or assignee is restricted under the Act.

     1.13 LIMITATIONS ON SUBSEQUENT REGISTRATION RIGHTS. From and after the date
of this Agreement, the Company shall not, without the prior written consent of
the Holders of a majority of the outstanding Registrable Securities then
outstanding, enter into any agreement with any holder or prospective holder of
any securities of the Company which would allow such holder or prospective
holder to interfere with or otherwise limit a Holder's registration rights under
this Agreement.

     1.14 REQUEST FOR REGISTRATION.

     (a) If the Company shall at any time during the Shelf Registration Period
be ineligible to use Form S-3 or Form S-3 shall be for any reason unavailable to
register the

                                        8
<PAGE>   12

Registrable Securities under the rules and regulation of the SEC, and the
duration of such ineligibility or unavailability exceeds or is expected to
exceed 60 days, the Holders shall have the right by a written request from the
Holders of a majority of the Registrable Securities then outstanding to the
Company, to require the Company to file a registration statement under the Act
covering the resales of at least 25% of the Registrable Securities then
outstanding (or a lesser percent if the anticipated aggregate offering price,
net of underwriting discounts and commissions, would exceed $10,000,000). Upon
its receipt of such a written request, the Company shall given written notice of
such request to all Holders within ten days thereof. The Company shall file as
soon as practicable, and in any event within 90 days of the receipt of such
request, a registration statement under the Act covering resales of all
Registrable Securities which Holders request to be registered, subject to the
limitations of subsection 1.14(b).

     (b) If the Holders initiating the registration request hereunder (the
"Initiating Holders") intend to distribute the Registrable Securities covered by
their request by means of an underwriting, they shall so advise the Company as a
part of their request made pursuant to subsection 1.14(a) and the Company shall
include such information in the written notice referred to in subsection
1.14(a). The managing underwriter shall be selected by a majority in interest of
the Initiating Holders and shall be reasonably acceptable to the Company. In
such event, the right of any Holder to include his Registrable Securities in
such registration shall be conditioned upon such Holder's participation in such
underwriting and the inclusion of such Holder's Registrable Securities in the
underwriting to the extent provided herein. All Holders proposing to distribute
their securities through such underwriting shall (together with the Company as
provided in subsection 1.4(e)) enter into an underwriting agreement in customary
form with the underwriter or underwriters selected for such underwriting.
Notwithstanding any other provision of this Section 1.14, if the underwriter
advises the Initiating Holders in writing that marketing factors require a
limitation of the number of shares to be underwritten, then the Initiating
Holders shall so advise all Holders of Registrable Securities which would
otherwise be underwritten pursuant hereto, and the number of shares of
Registrable Securities that may be included in the underwriting shall be
allocated among all Holders thereof, including the Initiating Holders, in
proportion (as nearly as practicable) to the amount of Registrable Securities of
the Company owned by each Holder.

     (c) The Company shall not be obligated to effect, or to take any action to
effect, any registration pursuant to this Section 1.14(a) after the Company has
effected two registrations pursuant to this Section 1.14(a) and such
registrations have been declared or ordered effective; provided however, that a
registration will not count as a registration pursuant to this Section 1.14(a)
unless the Holders requesting registration are able to register the offering of
and sell at least 50% of the shares of Registrable Securities that they have
requested be included in such registration.

     2.  RIGHTS OFFERING.

     2.1 RIGHTS.

     (a) As used herein, the term "Subsidiary" shall mean, with respect to the
Company, any direct or indirect subsidiary of the Company more than 50% of the
outstanding voting securities of which are owned directly or indirectly by the
Company. The Company shall,


                                        9
<PAGE>   13

upon receipt of a Rights Offering Notice (as defined below), cause the
Subsidiary designated as the "Relevant Subsidiary" in connection therewith (the
"Relevant Subsidiary"), to grant to the holders of the common stock of Safeguard
rights (the "Rights") to purchase from such Relevant Subsidiary such number of
shares of such Relevant Subsidiary's common stock as determined by Safeguard up
to a maximum of 40% of the sum of (i) all issued shares of common stock of such
Relevant Subsidiary, and (ii) all shares of common stock of such Relevant
Subsidiary subject to issuance pursuant to options, warrants or other
agreements, plans, instruments or understandings, all as of the effective date
of the registration statement relating to such Rights (the "Rights Registration
Statement"). The Rights shall be issued in an offering (the "Rights Offering")
pursuant to the Rights Registration Statement, shall be exercisable for a period
of no greater than 45 days after the commencement of the Rights Offering and
shall be transferable by the holder thereof during that period. The Company
shall cause the Relevant Subsidiary to engage an investment banking firm
selected by the Company, subject to the reasonable approval of Safeguard, which
firm shall underwrite, on a standby, firm commitment basis, any portion of the
offered common stock of the Relevant Subsidiary not purchased through the
exercise of Rights. The Company shall also engage legal counsel selected by
Safeguard, subject to the reasonable approval of a majority of the Board of
Directors of the Company, which counsel shall represent the Relevant Subsidiary
in connection with the conduct of the Rights Offering. The exercise price of the
Rights shall be determined by negotiation among the Relevant Subsidiary, the
underwriters and the selling stockholders, if any. Prior to the commencement of
the Rights Offering, the Company shall use its best efforts to cause (and shall
cause the Relevant Subsidiary to use its best efforts to cause) any holder of
more than 1% of the Relevant Subsidiary's common stock (or rights to acquire
more than 1% of the Relevant Subsidiary's common stock) and the Relevant
Subsidiary's officers and directors to execute and deliver to the underwriter of
the Rights Offering a market stand-off agreement. Such market stand-off
agreement shall provide that, during the period of duration specified by the
Relevant Subsidiary and the underwriter of common stock or other securities of
the Relevant Subsidiary following the effective date of the Rights Registration
Statement, such persons shall not, to the extent requested by the Relevant
Subsidiary and such underwriter, directly or indirectly sell, offer to sell,
contract to sell (including, without limitation, any short sale), grant any
option to purchase or otherwise transfer or dispose of (other than to donees who
agree to be similarly bound) any securities of the Relevant Subsidiary held by
them at any time during such period except common stock included in such Rights
Registration Statement.

     (b) Safeguard may initiate a Rights Offering with respect to any Subsidiary
by giving written notice to the Company (a "Rights Offering Notice") at any time
during the Rights Exclusivity Period (as hereinafter defined) at such time as
the total market value of such Subsidiary is at least $35,000,000, which
determination shall be made in good faith, upon request by Safeguard from time
to time, by the Board with the assistance and advice of such experts or
consultants as the Board may choose to retain, if any. The obligations of the
Company pursuant to this Section 2.1 shall commence on the date hereof and
expire on August 6, 2004 (such period, the "Rights Exclusivity Period"), unless
a registration statement relating to a Rights Offering has been filed with the
SEC by such date, in which case the Rights covered by such Registration
Statement shall not expire until 150 days after the date such filing was made.

     (c) The Company agrees that it will not (i) sell or otherwise transfer any
of the capital stock of any Subsidiary owned by it, (ii) permit any Subsidiary
to merge or consolidate


                                       10
<PAGE>   14

with any other person or entity other than the Company or another Subsidiary or
sell, lease or otherwise transfer any substantial portion of any Subsidiary's
assets, or (iii) permit any Subsidiary to undertake any registration of any of
its securities under the Act or the 1934 Act other than pursuant to this Section
2.1, in any case, prior to the earlier of the expiration of the Rights
Exclusivity Period or the completion of a Rights Offering with respect to such
Subsidiary, except with the consent of Safeguard.

     (d) Upon closing of a Rights Offering with respect to any Subsidiary,
Safeguard's right to require such Subsidiary to conduct any further Rights
Offerings under this Section 2 and any Directed Shares Offering under Section 3
below shall terminate.

     2.2 SPLIT. After Safeguard has notified the Company of its intention to
commence a Rights Offering, the Company shall, prior to the filing of the Rights
Registration Statement with respect thereto as provided hereinafter (or at such
earlier date as agreed to by the Company and Safeguard), take all such actions
as shall be necessary to cause the Relevant Subsidiary to cause a split of its
authorized common stock in such ratio as Safeguard shall determine. All
references to share amounts in this Agreement other than as specifically noted
shall be deemed to refer to share amounts prior to such split.

     2.3 REGISTRATION STATEMENT. Upon notice by Safeguard to the Company of its
intention to commence a Rights Offering, the Company shall cause the Relevant
Subsidiary to promptly prepare a Rights Registration Statement to register under
the Act, the Rights and the shares of the common stock of the Relevant
Subsidiary to be acquired upon exercise of the Rights (the "Rights Shares"). The
Company covenants that such Rights Registration Statement and the prospectus
included therein shall be in form reasonably satisfactory to Safeguard, shall
comply in all material respects with the Act and the rules and regulations of
the SEC promulgated thereunder, shall not contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading and shall conform with the provisions of
Section 1.4 hereof.

     2.4 REGISTRATION PROCESS. The Company shall use its best efforts to cause
the Relevant Subsidiary to cause the Rights Registration Statement to be filed
with the SEC and to become effective as promptly as practicable in accordance
with Section 1.4 hereof. The Company shall cause the Relevant Subsidiary to
prepare and file with the SEC, promptly upon Safeguard's request, any amendments
or supplements to the Rights Registration Statement or the related prospectus
that, in Safeguard's opinion, may be necessary or advisable in connection with
the Rights Offering, subject to the reasonable approval of counsel for the
Relevant Subsidiary. The Company shall not permit the Relevant Subsidiary to
file any amendment or supplement to the Rights Registration Statement or the
related prospectus unless (A) it has furnished Safeguard with a copy of such
amendment or supplement a reasonable time prior to filing and (B) Safeguard has
not reasonably objected to such amendment or supplement by notice to the Company
within 10 days of receipt of such copy. The Company shall not issue (and shall
not permit the Relevant Subsidiary to issue) any advertisement, press release,
mailing or other solicitation material of which Safeguard reasonably disapproves
by prompt written notice to the Company after receiving reasonable notice
thereof. The Company shall cause the Relevant Subsidiary to comply with the Act
and the rules and regulations thereunder in connection with



                                       11
<PAGE>   15

the Rights Offering and, until the termination of the Rights Offering, the
Company shall cause the Relevant Subsidiary to use its best efforts to qualify
the Rights Shares under the securities laws of all jurisdictions in which
qualification is required and there are holders of Safeguard common stock and to
continue such qualifications in effect during the exercise period of the Rights.
At the time of mailing the prospectus relating to the Rights Offering and at the
time of the closing of the Rights Offering, Safeguard shall be entitled to
receive (A) from the Company and the Relevant Subsidiary such certificates and
documents evidencing compliance with such representations and warranties of the
Company and the Relevant Subsidiary as Safeguard shall reasonably request of the
Company, and (B) from the counsel and independent accountants of the Company and
the Relevant Subsidiary such opinions and documents as Safeguard may reasonably
request thereof as if it were applicable to the Rights Offering.

     2.5 USE OF PROCEEDS. The Company shall cause the Relevant Subsidiary to
apply all proceeds of the Rights Offering first to the payment of the expenses
of the Rights Offering and thereafter to general working capital purposes or
such other purposes as shall be described in the related prospectus and agreed
to by Safeguard.

     2.6 REGISTRATION SERVICES.

     (a) Services. Safeguard shall diligently and in a timely fashion assist the
Company and the Relevant Subsidiary in structuring the Rights Offering, in
preparing the necessary registration statement and related disclosure
documentation, in clearing the Rights Offering with the SEC and applicable state
securities authorities and shall provide such other services and assistance in
connection with the Rights Offering as the Company or the Relevant Subsidiary
shall reasonably request. Nothing contained herein shall require Safeguard to
provide to the Company or the Relevant Subsidiary any services or assistance
which, if rendered by Safeguard, would require Safeguard to register as a
broker-dealer under Section 15 of the Exchange Act or any state securities laws,
or as an investment adviser under the Investment Advisor Act of 1940, as
amended.

     (b) Working Group. The Company shall cause the counsel, auditors,
employees, officers and consultants of the Company and the Relevant Subsidiary
to render such assistance in consummating the Rights Offering, at the expense of
the Company, as is customary in the consummation by a company of its initial
public offering. In addition, in rendering services under this Section 2.6,
Safeguard may engage special legal counsel, one or more rights, registrar and
transfer agents, and such other consultants as Safeguard may deem necessary or
desirable in connection with the Rights Offering, subject to the reasonable
approval of the Company, the expenses of which shall be paid by the Company and
which are not included in the reimbursement described in Subsection 2.6(c)
below. In addition, Safeguard may require the Relevant Subsidiary to engage a
registered broker-dealer of Safeguard's designation, subject to the reasonable
approval of the Company, to provide such services in connection with the Rights
Offering as Safeguard may deem reasonably necessary or desirable, including
without limitation, to effect or underwrite the offering of the Rights or the
Rights Shares in states in which applicable state laws require that a registered
broker-dealer effect such offering.

     (c) Expenses. The Company shall bear all reasonable costs and expenses of
the Rights Offering, including, but not limited to, the Relevant Subsidiary's
printing, legal and



                                       12
<PAGE>   16

accounting fees and expenses, SEC and NASD filing fees and "Blue Sky" fees and
expenses; provided, however, that the Company shall have no obligation to pay or
otherwise bear any portion of the underwriters' discounts attributable to the
Rights Shares not being offered and sold by the Relevant Subsidiary, or the fees
and expenses of counsel for the selling holders of Rights Shares in connection
with the registration of the Rights Shares if other than counsel to the Relevant
Subsidiary. The Company shall reimburse Safeguard for its internal expenses
incurred under this Section 2 by payment of $50,000 on a nonaccountable basis,
such payment to be made on the earlier of the closing of the Rights Offering or
90 days after the Registration Statement is filed.

     2.7 INDEMNIFICATION. In connection with the Rights Offering:

     (a) to the extent permitted by law, the Company will indemnify and hold
harmless Safeguard, any underwriter (as defined in the Act) for Safeguard and
each person, if any, who controls Safeguard or underwriter within the meaning of
the Act or the 1934 Act, against any losses, claims, damages, or liabilities
(joint or several) to which they may become subject under the Act, the 1934 Act
or other federal or state law, insofar as such losses, claims, damages, or
liabilities (or actions in respect thereof) arise out of or are based upon any
of the following statements, omissions or violations (collectively a
"Violation"): (i) any untrue statement or alleged untrue statement of a material
fact contained in such registration statement, including any preliminary
prospectus or final prospectus contained therein or any amendments or
supplements thereto, (ii) the omission or alleged omission to state therein a
material fact required to be stated therein, or necessary to make the statements
therein not misleading, or (iii) any violation or alleged violation by the
Company or the Relevant Subsidiary of the Act, the 1934 Act, any state
securities law or any rule or regulation promulgated under the Act, the 1934 Act
or any state securities law; and the Company will pay to Safeguard and each
underwriter or controlling person, as incurred, any legal or other expenses
reasonably incurred by them in connection with investigating or defending any
such loss, claim, damage, liability, or action; provided, however, that the
indemnity agreement contained in this subsection 2.7(a) shall not apply to: (x)
amounts paid in settlement of any such loss, claim, damage, liability, or action
if such settlement is effected without the consent of the Company (which consent
shall not be unreasonably withheld); (y) any such loss, claim, damage,
liability, or action to the extent that it arises out of or is based upon a
Violation which occurs in reliance upon and in conformity with written
information furnished expressly for use in connection with such registration by
Safeguard or the underwriter or controlling person; (z) any such loss, claim,
damage, liability or action to the extent that it arises out of or is based upon
Safeguard's or the underwriter's failure to deliver a copy of the registration
statement or prospectus or any amendments or supplements thereto;

     (b) to the extent permitted by law, Safeguard will indemnify and hold
harmless the Relevant Subsidiary, each of its directors, each of its officers
who has signed the registration statement, each person, if any, who controls the
Relevant Subsidiary within the meaning of the Act, any underwriter, any other
Holder selling securities in such registration statement and any controlling
person of any such underwriter or other Holder, against any losses, claims,
damages, or liabilities (joint or several) to which any of the foregoing persons
may become subject, under the Act, the 1934 Act or other federal or state law,
insofar as such losses, claims, damages, or liabilities (or actions in respect
thereto) arise out of or are based upon any Violation, in each case to the
extent (and only to the extent) that such Violation occurs in


                                       13
<PAGE>   17

reliance upon and in conformity with written information furnished by Safeguard
expressly for use in connection with such registration; and Safeguard will pay,
as incurred, any legal or other expenses reasonably incurred by any person
intended to be indemnified pursuant to this subsection 2.7(b), in connection
with investigating or defending any such loss, claim, damage, liability, or
action; provided, however, that the indemnity agreement contained in this
subsection 2.7(b) shall not apply to amounts paid in settlement of any such
loss, claim, damage, liability or action if such settlement is effected without
the consent of Safeguard, which consent shall not be unreasonably withheld;
provided, that, in no event shall any indemnity under this subsection 2.7(b)
exceed the gross public offering price of all such securities offered by
Safeguard and sold pursuant to such registration statement;

     (c) promptly after receipt by an indemnified party under this Section
2.7(c) of notice of the commencement of any action (including any governmental
action), such indemnified party will, if a claim in respect thereof is to be
made against any indemnifying party under this Section 2.7, deliver to the
indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party
(together with all other indemnified parties which may be represented without
conflict by one counsel) shall have the right to retain one separate counsel,
with the fees and expenses to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential differing
interests between such indemnified party and any other party represented by such
counsel in such proceeding. The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such
action, if prejudicial to its ability to defend such action, shall relieve such
indemnifying party of any liability to the indemnified party under this Section
2.7, but the omission so to deliver written notice to the indemnifying party
will not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 2.7;

     (d) if the indemnification provided for in this Section 2.7 is held by a
court of competent jurisdiction to be unavailable to an indemnified party with
respect to any loss, liability, claim, damage, or expense referred to therein,
then the indemnifying party, in lieu of indemnifying such indemnified party
hereunder, shall contribute to the amount paid or payable by such indemnified
party as a result of such loss, liability, claim, damage, or expense in such
proportion as is appropriate to reflect the relative fault of the indemnifying
party on the one hand and of the indemnified party on the other in connection
with the statements or omissions that resulted in such loss, liability, claim,
damage, or expense as well as any other relevant equitable considerations. The
relative fault of the indemnifying party and of the indemnified party shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission to state a material fact
relates to information supplied by the indemnifying party or by the indemnified
party and the parties' relative intent, knowledge, access to information, and
opportunity to correct or prevent such statement or omission. In no event shall
any contribution by Safeguard under this subsection 2.7(d) exceed the gross
public offering price of all such securities offered by Safeguard and sold
pursuant to such registration statement. In no event shall a person or entity
guilty of fraudulent misrepresentation (within the



                                       14
<PAGE>   18

meaning of Section 11(f) of the Act) be entitled to contribution from any person
or entity who was not guilty of fraudulent misrepresentation;

     (e) notwithstanding the foregoing, to the extent that the provisions on
indemnification and contribution contained in the underwriting agreement entered
into in connection with the underwritten public offering are in conflict with
the foregoing provisions, the provisions in the underwriting agreement shall
control; and

     (f) the obligations of the Company and Safeguard under this Section 2.7
shall survive the completion of the Rights Offering.

     3. DIRECTED SHARES OFFERING.

     3.1 DIRECTED SHARES REGISTRATION. Safeguard shall have the right to require
the Company to cause any Subsidiary to file a registration statement on Form S-1
for the registration of shares of the Subsidiary's common stock pursuant to this
Section 3 at such time as the total market value of such Subsidiary is at least
$35,000,000 (the "Directed Shares Offering"). Such registration statement shall
register common stock (i) sufficient in number to satisfy the Directed Shares
requirement described below and (ii) with an aggregate offering price, prior to
underwriting discounts and commissions, of at least $10,000,000. In connection
with such Directed Shares Offering, the Company shall cause the applicable
Subsidiary to adjust its authorized shares as requested by Safeguard in order to
facilitate distribution of Directed Shares to its stockholders. The Company
shall cause the applicable Subsidiary to engage (i) an underwriter or
underwriters selected by Safeguard, subject to the reasonable approval of a
majority of the Board of Directors of the Company, and (ii) legal counsel
selected by Safeguard, subject to the reasonable approval of a majority of the
Board of Directors of the Company, which counsel shall represent the applicable
Subsidiary in connection with the conduct of the Directed Shares Offering.

     3.2 DIRECTED SHARES SUBSCRIPTION PROGRAM. In connection with the Directed
Shares Offering, the Company shall cause the applicable Subsidiary to:

     (a) provide in the related underwriting agreement a right for Safeguard to
designate persons (the "Safeguard Designees") who may purchase from the
underwriter(s) shares of the Relevant Subsidiary's common stock (the "Directed
Shares") at the public offering price of such Subsidiary's common stock in the
Directed Shares Offering (the "IPO Price"); and

     (b) use its best efforts to cause such Subsidiary to cause the underwriters
of the Directed Shares Offering to allow the Safeguard Designees to purchase at
the IPO Price that number of Directed Shares equal to the greater of (i) 20% of
the shares of common stock offered by such Subsidiary in such Directed Shares
Offering or (ii) 10% of the number of shares of Safeguard Common Stock
outstanding on the record date set by Safeguard for distribution of Directed
Shares (or subscription rights therefor) to its stockholders. Upon closing of
the Directed Shares Offering with respect to any Subsidiary and sale of the
number of shares set forth in this Section 3.2(b), Safeguard's right to require
the Company to cause such Subsidiary to conduct a Rights Offering pursuant to
Section 2 above shall terminate. The Company shall reimburse Safeguard for its
internal expenses incurred under this Section 3 by payment of


                                       15
<PAGE>   19

$50,000 on a nonaccountable basis, such payment to be made on the earlier of the
closing of the Directed Shares Offering or 90 days after the Registration
Statement is filed.
